Item 1. Business

General

Welltower Inc. (NYSE:WELL), an S&P 500 company headquartered in Toledo, Ohio, is driving the transformation of health care infrastructure. The company invests with leading seniors housing operators, post-acute providers and health systems to fund the real estate and infrastructure needed to scale innovative care delivery models and improve people’s wellness and overall health care experience. Welltower™, a real estate investment trust (“REIT”), owns interests in properties concentrated in major, high-growth markets in the United States (“U.S.”), Canada and the United Kingdom (“U.K.”), consisting of seniors housing, post-acute communities and outpatient medical properties. More information is available on the Internet at www.welltower.com. The information on our website is not incorporated by reference in this Annual Report on Form 10-K, and our web address is included as an inactive textual reference only.

Our primary objectives are to protect stockholder capital and enhance stockholder value. We seek to pay consistent cash dividends to stockholders and create opportunities to increase dividend payments to stockholders as a result of annual increases in net operating income and portfolio growth. To meet these objectives, we invest across the full spectrum of seniors housing and health care real estate and diversify our investment portfolio by property type, relationship and geographic location.

On March 7, 2022, we announced our intent to complete an UPREIT reorganization. In February 2022, the company formerly known as Welltower Inc. ("Old Welltower") formed WELL Merger Holdco Inc. ("New Welltower") as a wholly owned subsidiary, and New Welltower formed WELL Merger Holdco Sub Inc. ("Merger Sub") as a wholly owned subsidiary. On April 1, 2022, Merger Sub merged with and into Old Welltower, with Old Welltower continuing as the surviving corporation and a wholly owned subsidiary of New Welltower (the "Merger"). In connection with the Merger, Old Welltower's name was changed to "Welltower OP Inc.", and New Welltower inherited the name "Welltower Inc." Effective May 24, 2022, Welltower OP Inc. ("Welltower OP") converted from a Delaware corporation into a Delaware limited liability company named Welltower OP LLC (the "LLC Conversion"). Following the LLC Conversion, New Welltower's business continues to be conducted through Welltower OP and New Welltower does not have substantial assets or liabilities, other than through its investment in Welltower OP.

Welltower Inc. is the initial member and majority owner of Welltower OP, with an approximate ownership interest of 99.751% as of December 31, 2022. Welltower Inc. issues equity from time to time, the net proceeds of which it is obligated to contribute as additional capital to Welltower OP. All debt including credit facilities, senior notes and secured debt is incurred by Welltower OP, and Welltower Inc. has fully and unconditionally guaranteed all existing and future senior unsecured notes.

Unless stated otherwise or the context otherwise requires, references to "Welltower" mean Welltower Inc. and references to "Welltower OP" mean Welltower OP LLC. References to “we,” “us,” “our” or the “company” mean collectively Welltower, Welltower OP and those entities/subsidiaries owned or controlled by Welltower and/or Welltower OP.

Portfolio of Properties

Please see “Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operation – Executive Summary – Company Overview” for a table that summarizes our portfolio as of December 31, 2022.

Property Types

We invest in seniors housing and health care real estate and evaluate our business through three reportable segments: Seniors Housing Operating, Triple-net and Outpatient Medical. For additional information regarding our segments, please see Note 18 to our consolidated financial statements. The accounting policies of the segments are the same as those described in the summary of significant accounting policies in Note 2 to our consolidated financial statements. The following is a summary of our various property types.

Seniors Housing Operating

Our Seniors Housing Operating properties include seniors apartments, independent living and independent supportive living, continuing care retirement communities, assisted living, Alzheimer's/dementia care and include care homes with or without nursing (U.K.), which assist with activities of daily living that preserve a person's mobility and social systems to promote cognitive engagement. Our properties include stand-alone properties that provide one level of service, combination properties that provide multiple levels of service and communities or campuses that provide a wide range of services. Properties are primarily held in joint venture entities with operating partners. We utilize the structure authorized by the REIT Investment Diversification and Empowerment Act of 2007, which is commonly referred to as a “RIDEA” structure (the provisions of the Internal Revenue Code authorizing the RIDEA structure were enacted as part of the Housing and Economic Recovery Act of 2008).

Seniors Apartments Seniors apartments generally refer to age-restricted multi-unit housing with self-contained living units for older adults, usually aged 55+ who are able to care for themselves. Seniors apartments generally do not offer other additional services such as meals.

Independent Living and Independent Supportive Living (Canada) Independent living and independent supportive living generally refers to age-restricted, multifamily properties with central dining that provide residents access to meals and other services such as housekeeping, linen service, transportation and social and recreational activities.

Continuing Care Retirement Communities Continuing care retirement communities typically include a combination of detached homes and properties offering independent living, assisted living and/or long-term/post-acute care services on one campus. These communities appeal to residents because there is no need to relocate when health and medical needs change. Resident payment plans vary, but can include entrance fees, condominium fees and rental fees. Many of these communities also charge monthly maintenance fees in exchange for a living unit, meals and some health services.

Assisted Living Assisted living refers to state-regulated rental properties that provide independent living services, but also provide supportive care from trained employees to residents who require assistance with activities of daily living, including, but not limited to, management of medications, bathing, dressing, toileting, ambulating and eating.

Alzheimer’s/Dementia Care Alzheimer's/Dementia Care refers to state-regulated rental properties that generally provide assisted living and independent living services, but also provide supportive care to residents with memory loss, Alzheimer's disease and/or other types of dementia. Amenities vary, but may include enhanced security, specialized design features and memory-enhancing therapies that promote relaxation and help slow cognitive decline.

Care Homes with or without Nursing (U.K.) Care homes without nursing, regulated by the Care Quality Commission ("CQC”), are rental properties that provide essentially the same services as U.S. assisted living. Care homes with nursing, also regulated by the CQC, are licensed daily rate or rental properties where most individuals require 24-hour nursing and/or medical care. Generally, these properties are licensed for various national and local reimbursement programs. Unlike the U.S., care homes with nursing in the U.K. generally do not provide post-acute care.

Our Seniors Housing Operating segment accounted for 72%, 68% and 67% of total revenues for the years ended December 31, 2022, 2021 and 2020, respectively. As of December 31, 2022, we had relationships with 43 operators to manage our Seniors Housing Operating properties. In each instance, our partner provides management services to the properties pursuant to an incentive-based management contract. We rely on our partners to effectively and efficiently manage these properties. For the year ended December 31, 2022, our relationship with Sunrise Senior Living accounted for approximately 20% of our Seniors Housing Operating segment revenues and 14% of our total revenues. Additionally Revera accounted for approximately 8% of our Seniors Housing Operating segment revenues and 6% our total revenues. Revera owns a controlling interest in Sunrise Senior Living.

Triple-net

Our Triple-net properties offer services including independent living and independent supportive living (Canada), assisted living, continuing care retirement communities, Alzheimer's/dementia care and care homes with or without nursing (U.K.) described above, as well as long-term/post-acute care. Our properties include stand-alone properties that provide one level of service, combination facilities that provide multiple levels of service, and communities or campuses that provide a wide range of services. We invest primarily through acquisitions, development and joint venture partnerships. Our properties are primarily leased to operators under long-term, triple-net master leases that obligate the tenant to pay all operating costs, utilities, real estate taxes, insurance, building repairs, maintenance costs and all obligations under certain ground leases. We are not involved in property management.

Long-Term/Post-Acute Care Facilities Post-acute care is at the leading edge of reducing health care costs while improving quality. These high-impact centers help patients recover from illness or surgery with the goals of getting the patient home and healed faster and reducing hospital readmission rates. Our long-term/post-acute care properties generally offer skilled nursing/post-acute care, inpatient rehabilitation and long-term acute care services. Skilled nursing/post-acute care refers to licensed daily rate or rental properties where most individuals require 24-hour nursing and/or medical care. Generally, these properties are licensed for Medicaid and/or Medicare reimbursement in the U.S. or provincial reimbursement in Canada. All properties offer some level of rehabilitation services. Some properties focus on higher acuity patients and offer rehabilitation units specializing in cardiac, orthopedic, dialysis, neurological or pulmonary rehabilitation. Inpatient rehabilitation properties provide intensive inpatient services after illness, injury or surgery to patients able to tolerate and benefit from three hours of rehabilitation per day. Long-term acute care properties provide inpatient services for patients with complex medical conditions that require more intensive care, monitoring or emergency support than is available in most skilled nursing/post-acute care properties.

Our Triple-net segment accounted for 16%, 19% and 17% of total revenues for the years ended December 31, 2022, 2021 and 2020, respectively. For the year ended December 31, 2022, our revenues related to our relationship with ProMedica Health System ("ProMedica") accounted for approximately 26% of our Triple-net segment revenues and 4% of total revenues. In December 2022, ProMedica relinquished to Welltower its 15% interest in 147 skilled nursing facilities previously owned by the Welltower/ProMedica joint venture in exchange for a lease modification, which relieved ProMedica from its lease obligation on the 147 skilled nursing properties and amended the lease on the remaining 58 assisted living and memory care properties that

continue to be held by the Welltower/ProMedica joint venture. The 58 assisted living and memory care assets continue to be operated by ProMedica and backed by the existing guaranty. Concurrently, Welltower and Integra Healthcare Properties ("Integra") entered into master leases for the skilled nursing portfolio. Approximately 15 regional operators will enter into subleases with Integra to operate the properties. Also in December 2022 and January 2023, we sold to Integra a 15% ownership interest in 85 of those skilled nursing facilities and Integra is expected to buy into the remaining 62 assets throughout 2023.

For the year ended December 31, 2022, our revenues related to our relationship with Genesis Healthcare ("Genesis") accounted for approximately 2% of our Triple-net segment revenues and less than 1% of our total revenues. During 2020, Genesis indicated substantial doubt as to their ability to continue as a going concern. As a result, effective July 1, 2020, we recognized reserves for all existing straight-line rent receivable balances of $91,025,000 as a reduction to rental income and now recognize rental income from Genesis on a cash basis. Additionally, in March 2021, we entered into definitive agreements to substantially exit our operating relationship with Genesis. As of December 31, 2022, our relationship with Genesis was comprised of one property owned 100% by us and leased to Genesis, a loan balance net of allowance for credit losses of $168,949,000, approximately 9.5 million shares of GEN Series A common stock and a 25% ownership stake in an unconsolidated joint venture that includes two master leases for 28 properties operated by Genesis.

Outpatient Medical

Outpatient Medical Buildings Demand for outpatient medical services is growing as more procedures are performed safely and efficiently outside the hospital setting. State-of-the-art outpatient centers are needed in accessible, consumer-friendly locations. Our portfolio of outpatient medical buildings is an integral part of creating health care provider connectivity in local markets and generally include physician offices, ambulatory surgery centers, diagnostic facilities, outpatient services and/or labs. Approximately 87% of our outpatient medical building portfolio is affiliated with health systems (buildings directly on or adjacent to hospital campuses or with tenants that are satellite locations for the health system and its physicians). We typically lease our outpatient medical buildings to multiple tenants and provide varying levels of property management. Our Outpatient Medical segment accounted for 12%, 13% and 16% of total revenues for each of the years ended December 31, 2022, 2021 and 2020, respectively. No single tenant exceeds 20% of segment revenues.

Investments

Providing high-quality and affordable health care to an aging global population requires vast investments and infrastructure development. We invest in seniors housing and health care real estate primarily through acquisitions, developments and joint venture partnerships. For additional information regarding acquisition and development activity, please see Note 3 to our consolidated financial statements. Our portfolio creates opportunities to connect partners across the continuum of care and drive efficiency. We seek to diversify our investment portfolio by property type, relationship and geographic location. In determining whether to invest in a property, we focus on the following: (1) the experience of the obligor’s/partner’s management team; (2) the historical and projected financial and operational performance of the property; (3) the credit of the obligor/partner; (4) the security for any lease or loan; (5) the real estate attributes of the building and its location; (6) the capital committed to the property by the obligor/partner; and (7) the operating fundamentals of the applicable industry.

We monitor our investments through a variety of methods determined by the type of property. Our asset management process for seniors housing properties generally includes review of monthly financial statements and other operating data for each property, review of obligor/partner creditworthiness, property inspections, and review of covenant compliance relating to licensure, real estate taxes, letters of credit and other collateral. Our internal property management division manages and monitors the outpatient medical portfolio with a comprehensive process including review of, among other things, tenant relations, lease expirations, the mix of health service providers, hospital/health system relationships, property performance, capital improvement needs, and market conditions.

Investment Types

Real Property Our properties are primarily comprised of land, buildings, improvements and related rights. Our triple-net properties are generally leased to operators under long-term operating leases. The leases generally have a fixed contractual term of 12 to 15 years and contain one or more five to 15-year renewal options. Certain of our leases also contain purchase options, a portion of which could result in the disposition of properties for less than full market value if the options were to be exercised. Most of our rents are received under triple-net leases requiring the operator to pay rent and all additional charges incurred in the operation of the leased property. The tenants are required to repair, rebuild and maintain the leased properties. Substantially all these operating leases are designed with escalating rent structures. Leases with fixed annual rental escalators are generally recognized on a straight-line basis over the initial lease period, subject to a collectability assessment. Rental income related to leases with contingent rental escalators is generally recorded based on the contractual cash rental payments due for the period.

At December 31, 2022, approximately 96% of our triple-net properties were subject to master leases. A master lease is a lease of multiple properties to one tenant entity under a single lease agreement. From time to time, we may acquire additional properties that are then leased to the tenant under the master lease. The tenant is required to make one monthly payment that represents rent on all the properties that are subject to the master lease. Typically, the master lease tenant can exercise its right to purchase the properties or to renew the master lease only with respect to all leased properties at the same time. We believe this bundling feature benefits us because the tenant cannot limit the purchase or renewal to better performing properties and terminate the leasing arrangement with respect to poorer performing properties. This spreads our risk among the entire group of properties within the master lease. The bundling feature should provide a similar advantage to us if the master lease tenant is in bankruptcy. Subject to certain restrictions, a debtor in bankruptcy has the right to assume or reject its unexpired leases and executory contracts. In the context of integrated master leases such as ours, our tenants in bankruptcy would be required to assume or reject the master lease as a whole, rather than deciding on a property by property basis.

Our Outpatient Medical portfolio is primarily self-managed and consists mainly of multi-tenant properties leased to health care providers. Our leases typically include increasers and some form of operating expense reimbursement by the tenant. As of December 31, 2022, 62% of our portfolio included leases with full pass through, 31% with a partial expense reimbursement (modified gross) and 7% with no expense reimbursement (gross). Our outpatient medical leases are non-cancellable operating leases that have a weighted-average remaining term of seven years at December 31, 2022 and are often credit enhanced by security deposits, guarantees and/or letters of credit.

Construction We provide funds for the construction of properties for tenants primarily as part of long-term operating leases. We capitalize certain interest costs associated with funds used for the construction of properties owned by us. The amount capitalized is based upon the amount advanced during the construction period using the rate of interest that approximates our company-wide cost of financing. Our interest expense is reduced by the amount capitalized. The construction period commences upon initial funding and terminates upon the earlier of the completion of the applicable property or the end of a specified period. During the construction period, we advance funds to the tenants in accordance with agreed upon terms and conditions which require, among other things, periodic site visits by a company representative. During the construction period, we generally require an additional credit enhancement in the form of payment and performance bonds and/or completion guarantees. At December 31, 2022, we had outstanding construction investments of $1,021,080,000 and were committed to provide additional funds of approximately $1,883,449,000 to complete construction for consolidated investment properties. We also provide for construction loans which, depending on the terms and conditions, could be treated as loans or investments in unconsolidated entities.

Loans Our real estate loans are typically structured to provide us with interest income, principal amortization and transaction fees. Real estate loans consist of mortgage loans and other real estate loans which are primarily collateralized by a first, second or third mortgage lien, a leasehold mortgage on, or an assignment of the partnership interest in the related properties, corporate guarantees and/or personal guarantees. Non-real estate loans are generally corporate loans with no real estate backing. At December 31, 2022, we had outstanding loans, net of allowances, of $1,180,012,000 with an interest yield of approximately 9.9% per annum. Our yield on loans depends upon a number of factors, including the stated interest rate, average principal amount outstanding during the term of the loan and any interest rate adjustments. The loans outstanding at December 31, 2022 are generally subject to one to 15-year terms with principal amortization schedules and/or balloon payments of the outstanding principal balances at the end of the term.

Investments in Unconsolidated Entities Investments in entities that we do not consolidate but for which we can exercise significant influence over operating and financial policies are reported under the equity method of accounting. At December 31, 2022, we had investments in unconsolidated entities of $1,499,790,000. Our investments in unconsolidated entities generally represent interests ranging from 10% to 88% in real estate assets. Under the equity method of accounting, our share of the investee’s earnings or losses is included in our consolidated results of operations. The initial carrying value of investments in unconsolidated entities is based on the amount paid to purchase the entity interest inclusive of transaction costs. We evaluate our equity method investments for impairment based upon a comparison of the estimated fair value of the equity method investment to its carrying value. When we determine a decline in the estimated fair value of such an investment below its carrying value is other-than-temporary, an impairment is recorded.

In Substance Real Estate Additionally, we provide loans to third parties for the acquisition, development and construction of real estate. Under these arrangements, it is possible that we will participate in the expected residual profits of the project through the sale, refinancing or acquisition of the property. We evaluate the characteristics of each arrangement, including its risks and rewards, to determine whether they are more similar to those associated with a loan or an investment in real estate. Arrangements with characteristics implying real estate joint ventures are treated as in substance real estate investments, accounted for using the equity method, and are presented as investments in unconsolidated entities. We have made loans related to 21 properties with a carrying value of $649,267,000 as of December 31, 2022, which are classified as in substance real estate investments.

Principles of Consolidation

The consolidated financial statements are in conformity with U.S general accepted accounting principles (“U.S. GAAP”) and include the accounts of our wholly-owned subsidiaries and joint venture entities that we control, through voting rights or other means. All material intercompany transactions and balances have been eliminated in consolidation.

At inception of joint venture transactions, we identify entities for which control is achieved through means other than voting rights (“variable interest entities” or “VIEs”) and determine which business enterprise is the primary beneficiary of its operations. A VIE is broadly defined as an entity where either (i) the equity investors as a group, if any, do not have a controlling financial interest, or (ii) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support. We consolidate investments in VIEs when we are determined to be the primary beneficiary. Accounting Standards Codification Topic 810, "Consolidations", requires enterprises to perform a qualitative approach to determining whether or not a VIE will need to be consolidated. This evaluation is based on an enterprise’s ability to direct and influence the activities of a VIE that most significantly impact that entity’s economic performance.

For investments in joint ventures, U.S. GAAP may preclude consolidation by the sole general partner in certain circumstances based on the type of rights held by the limited partner(s). We assess the limited partners’ rights and their impact on our consolidation conclusions, and we reassess if there is a change to the terms or in the exercisability of the rights of the limited partners, the sole general partner increases or decreases its ownership of limited partnership interests, or there is an increase or decrease in the number of outstanding limited partnership interests. We similarly evaluate the rights of managing members of limited liability companies.

Borrowing Policies

We utilize a combination of debt and equity to fund investments. Generally, we intend to issue unsecured, fixed-rate public debt with long-term maturities to approximate the maturities on our triple-net leases and investment strategy. For short-term purposes, we may borrow on our primary unsecured credit facility or issue commercial paper. We typically replace these borrowings with long-term capital such as senior unsecured notes or common stock. When terms are deemed favorable, we may invest in properties subject to existing mortgage indebtedness. In addition, we may obtain secured financing for unleveraged properties in which we have invested or may refinance properties acquired on a leveraged basis. In certain agreements with our lenders, we are subject to restrictions with respect to secured and unsecured indebtedness.

Competition

We compete with other real estate investment trusts, real estate partnerships, private equity and hedge fund investors, banks, insurance companies, finance/investment companies, government-sponsored agencies, taxable and tax-exempt bond funds, health care operators, developers and other investors in the acquisition, development, leasing and financing of health care and seniors housing properties. We compete for investments based on a number of factors including relationships, certainty of execution, investment structures and underwriting criteria. Our ability to successfully compete is impacted by economic and demographic trends, availability of acceptable investment opportunities, our ability to negotiate beneficial investment terms, availability and cost of capital, construction and renovation costs and applicable laws and regulations.

The operators/tenants of our properties compete with properties that provide comparable services in the local markets. Operators/tenants compete for patients and residents based on a number of factors including quality of care, reputation, physical appearance of properties, location, services offered, family preferences (including a preference for home health services instead of residing in one of our communities), physicians, staff and price. We also face competition from other health care facilities for tenants, such as physicians and other health care providers that provide comparable facilities and services.

For additional information on the risks associated with our business, please see “Item 1A — Risk Factors” of this Annual Report on Form 10-K.

Environmental, Social and Governance

Environmental, Social and Governance ("ESG") Approach We are committed to operating in a responsible, transparent and sustainable manner. Our leadership (through the ESG Steering Committee launched in 2022) and Board of Directors (through the Nominating Corporate/Governance Committee), oversee and advance our ESG initiatives. We recognize that focusing on ESG engagement, integration and impact benefit our stakeholders and are fundamental to our business. Our corporate responsibility and sustainability strategy is focused on adopting leading ESG practices across our business and we were recognized for our leadership in this space over the past year in the following ways:

• Recognized at the Management band level with a CDP score of “B” for taking coordinated action on climate issues;

• Raised MSCI ESG rating from AA to AAA;

• Listed in the FTSE4Good Index since 2012;

• Recognized by the U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy as an ENERGY STAR Partner of the Year for the fourth consecutive year and maintained the level of Sustained Excellence, the EPA’s highest recognition within the ENERGY STAR program;

• Maintained top 30% (3rd decile) ISS Quality Score ranking for each Governance, Environment and Social;

• Named to the Bloomberg Gender-Equality Index for the fourth consecutive year;

• Maintained Prime status under the ISS-ESG Corporate rating for the fourth consecutive year;

• Improved GRESB score and maintained GRESB Green Star status;

• Named by S&P Global in the 2022 edition of The Sustainability Yearbook;

• Recognized by Labrador as a 2022 Transparency Award winner in the real estate industry for our clear and concise disclosure of relevant information to stakeholders in our annual proxy statement, Form 10-K, and investor relations website

• Named to the top 30 percent of Newsweek’s America’s Most Responsible Companies list for the fourth consecutive year; and

• Named to Sustainalytics 2022 Top-Rated ESG Companies list.

Environmental We strive to reduce our environmental impact by increasing energy and water efficiency, reducing greenhouse gas emissions, and by investing in projects that reduce energy and water consumption that meet our rate of return threshold. After several years of portfolio and program evolution, along with our increased ability to collect data in partnership with our operators and tenants, our property-level sustainability dataset (energy, greenhouse gas ("GHG"), water, and waste) is evolving to become a set of tools for benchmarking. A portion of our self-managed Outpatient Medical portfolio is benchmarked in EPA ENERGY STAR Portfolio Manager ("ESPM") and we regularly engage with our operators and tenants on ENERGY STAR, utility bill aggregators, utility companies, and others to add to our number of ESPM benchmarked properties throughout our portfolio.

We have employee, tenant, operator/manager and vendor engagement programs in place, focused on operational strategies to drive energy and water efficiency. We have issued guidance with accompanying training to assist them to successfully benchmark our buildings and to engage them to improve energy and water efficiency, as well as increase their recycling diversion rates.

In December 2019, we issued our inaugural green bond of $500,000,000 of 2.700% senior unsecured notes due 2027 and in March 2022 we issued an additional green bond of $550,000,000 of 3.85% senior unsecured notes due 2032. The net proceeds from the offerings have been, and continue to be, used to fund energy efficiency, water conservation and green building projects. As of September 30, 2022, we have utilized $572,090,000 of proceeds from these issuances on such projects.

We understand that as we continue to make our operations and buildings more sustainable, we also have a responsibility to effectuate the same in our supply chain and our purchasing decisions. As such, we partner with suppliers that offer take back programs for their products, look for the ENERGY STAR label when purchasing eligible items, seek to purchase office supply products that contain recycled content and purchase paper products that are either Forest Stewardship Council or Sustainable Forestry Initiative certified.

Social We value and are committed to our employees. We believe that a diverse workplace produces a variety of perspectives, motivates employees and helps us understand and better serve our stakeholders, and the communities in which we do business. As of December 31, 2022, our U.S. employees self-identified as follows:

Ethnicity						Male						Female
Asian						7		%				9		%
Black or African American						4		%				8		%
Hispanic or Latino						8		%				7		%
Native Hawaiian or Other Pacific Islander						—		%				1		%
Two or More Races						1		%				2		%
White						80		%				73		%
						100		%				100		%
Gender						51		%				49		%

We have reinforced our already strong commitment to diversity and inclusion through our Diversity Council and support of our eight employee network groups ("ENGs"). Our ENGs include women, families, racial and ethnic minorities, military, young professionals, and those who identify as LGBTQI+ and their allies. Our ENGs provide support, education, networking opportunities and community belonging for our employees. Our support of diversity and inclusion through our Diversity

Council and ENGs, taken together with other employee initiatives, such as tailored messaging, training and discussions on equality and belonging, support our efforts to compete for and foster talent and inclusiveness in an ever-changing workforce.

In addition, we have several social initiatives in place that are focused on fostering a more diverse workforce, engaging with our communities and promoting the health and well-being of our employees, tenants and residents. The Welltower Charitable Foundation (the "Foundation") financially supports charitable initiatives related to aging, health care, the environment, education and the arts. Since its inception, the Foundation has provided more than $42 million in cash and in-kind support. We encourage our employees to give back to the community by matching their contributions and donating their time to eligible charitable organizations. Funds are also allocated to each of our ENGs to make charitable contributions in support of their programming efforts. Additionally, the Foundation facilitates presentations for charities to compete in the Give-WELL campaign. This campaign enables our employees to present and vote for charities that will receive donations from the Foundation. During 2022, we sponsored our third annual Day of Giving so our employees could collaborate to make an impact with local charitable organizations through volunteer opportunities. See Human Capital section below for additional information regarding employee initiatives and programs.

Governance Our commitment to diversity starts at the top with a highly knowledgeable, skilled and diverse Board of Directors. As of December 31, 2022, our ten Directors self-identified as follows:

Board Composition
Ethnicity												Gender
Asian						10		%				Male						60		%
Black or African American						20		%				Female						40		%
Hispanic or Latino						20		%										100		%
White						50		%
						100		%

Nine of our ten Directors are independent and the independent Chair of our Board is held by a Black/African American male. Four of five, or 80%, of our Board committees are chaired by either a Female (2), Hispanic/Latino (1) or Black/African American (1) Director.

Additional information regarding our ESG programs and initiatives is available in our 2021 Environmental, Social and Governance Report (located on our website at www.welltower.com). Information on our website, including our Environmental, Social and Governance Report or sections thereof, is not incorporated by reference into this Annual Report.

Human Capital

Our employees are our greatest asset. As of December 31, 2022, we had 514 employees (491 located in United States, 14 in the United Kingdom, eight in Canada and one in Luxembourg). We are committed to the success of our people and the unique combination of skills and experiences they bring to achieving our mission.

Employee Engagement High employee engagement and satisfaction are critical to attracting and retaining top talent. During 2022, we conducted an employee engagement survey through an independent third party, measuring our progress on important employee issues such as manager relationships, employee empowerment, performance management and resources and support, and identifying opportunities for growth and improvement. The 2022 overall engagement score improved over the 2021 engagement score as a result of managers taking action on the 2021 results.

Employee Development Programs and Performance Management Development through the talent pipeline, recognizing and rewarding performance and providing opportunities for continued growth are the cornerstones of our Human Capital strategy. We offer employees resources, trainings and tools designed to develop future leaders, advance careers and attract and retain talent including but not limited to our robust early career programs, formal mentorship and coaching programs, manager development training, skill development courses and education assistance. During 2022, we continued executive management coaching programs to equip leaders with structured 360 feedback, customized development plans and guidance on company-wide succession planning. For some leaders, we partnered with a virtual coaching platform that scales individual access to expert coaches, training opportunities and enables behavioral change through award-winning artificial intelligence. For our senior vice presidents, we partnered with an independent advisory firm to provide one-on-one coaching, including an extensive 360 feedback process to focus on maximizing their executive leadership potential.

Compensation and Benefits In addition to salary, our compensation and benefits programs include annual short term incentive bonuses, long-term incentive stock awards, retirement plans, an employee stock purchase plan, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off, parental and caregiver leave, senior wellness leave, employee assistance programs, tuition assistance and health and wellness reimbursement programs, among many others. With the assistance of independent third parties, we annually evaluate and benchmark the competitiveness of our compensation and benefits programs focusing on fair pay practices that reward performance and support the needs of our employees.

Health, Safety and Wellness The success of our business is fundamentally connected to the safety and well-being of our employees, tenants, operators and managers, and their residents and visitors, as the case may be. We provide our employees and their families with access to numerous innovative, flexible and convenient health and wellness programs that support physical, mental and financial well-being. While COVID-19 continued in 2022, our focus remained on providing a safe office environment for our employees while continuing to allow for remote work, hybrid work and flexible work schedules where feasible. With the support of the varying work arrangements and a geographically dispersed workforce, we continued to develop ways to best support our people. We improved our employee experience by growing our internal communication platform (intranet), enhancing connectivity and collaboration. The mobile application created an easily accessible digital home-base where all company communications, including important office announcements, must-read company articles and external media engagements are located. Additional communication tools, including podcasts, town hall meetings, team events (virtually and in person) and dedicated communication channels for ENGs, demonstrate our commitment to ensuring employee alignment and engagement. Although workplace injuries are minimal, our safety committee implemented a workforce injury root cause analysis program to ensure we focus on future incident prevention and improvement.

Certain Government Regulations

United States

Health Law Matters — Generally

Typically, operators of seniors housing facilities do not receive significant funding from government programs and are largely subject to state laws, as opposed to federal laws. Operators of long-term/post-acute care facilities and hospitals do receive significant funding from government programs, and these facilities are subject to extensive regulation, including federal and state laws covering the type and quality of medical and/or nursing care provided, ancillary services (e.g., respiratory, occupational, physical and infusion therapies), qualifications of the administrative personnel and nursing staff, the adequacy of the physical plant and equipment, reimbursement and rate setting and operating policies. In addition, as described below, operators of these facilities are subject to extensive laws and regulations pertaining to health care fraud and abuse, including, but not limited to, the federal Anti-Kickback Statute (“AKS”), the federal Stark Law (“Stark Law”), and the federal False Claims Act (“FCA”), as well as comparable state laws. Hospitals, physician group practice clinics, and other health care providers that operate in our portfolio are subject to extensive federal, state, and local licensure, registration, certification, and inspection laws, regulations, and industry standards, as well as other conditions of participation in federal and state government programs such as Medicare and Medicaid. Further, operators of long-term care facilities are required to have in place compliance and ethics programs that meet the requirements of federal laws and regulations. Our tenants’ failure to comply with applicable laws and regulations could result in, among other things: loss of accreditation; denial of reimbursement; imposition of fines; suspension, decertification, or exclusion from federal and state health care programs; loss of license; or closure of the facility. See risk factors “The requirements of, or changes to, governmental reimbursement programs, such as Medicare or Medicaid, could have a material adverse effect on our obligors’ liquidity, financial condition and results of operations, which could adversely affect our obligors’ ability to meet their obligations to us” and “Our operators’ or tenants’ failure to comply with federal, state, local, and industry-regulated licensure, certification and inspection laws, regulations, and standards could adversely affect such operators’ or tenants’ operations, which could adversely affect our operators’ and tenants’ ability to meet their obligations to us” in “Item 1A – Risk Factors” below. Moreover, in light of certain arrangements that Welltower may pursue with healthcare entities who are directly subject to laws and regulations pertaining to health care fraud and abuse, and, given that certain of our arrangements are structured under the provisions of the REIT Investment Diversification and Empowerment Act of 2007 ("RIDEA"), certain health care fraud and abuse laws and data privacy laws could apply directly to Welltower. See risk factor "We assume operational and legal risks with respect to our properties managed in RIDEA structures that could have a material adverse effect on our business results of operations, and financial condition" in "Item 1A - Risk Factors" below.

Licensing and Certification

The primary regulations that affect seniors housing facilities are state licensing and certification laws. For example, certain health care facilities are subject to a variety of licensure and certificate of need (“CON”) laws and regulations. Where applicable, CON laws generally require, among other requirements, that a facility demonstrate the need for (1) constructing a new facility, (2) adding beds or expanding an existing facility, (3) investing in major capital equipment or adding new services, (4) changing the ownership or control of an existing licensed facility or (5) terminating services that have been previously approved through the CON process. Certain state CON laws and regulations may restrict the ability of operators to add new properties or expand an existing facility’s size or services. In addition, CON laws may constrain the ability of an operator to transfer responsibility for operating a particular facility to a new operator.

With respect to licensure, generally our long-term/post-acute care facilities are required to be licensed by the applicable state regulatory authority and certified for participation in Medicare, Medicaid and other federal and state health care programs. The failure of our operators to maintain or renew any required license or regulatory approval as well as the failure of our operators to correct serious deficiencies identified in a compliance survey could require those operators to discontinue operations at a property. In addition, if a property is found to be out of compliance with Medicare, Medicaid or other federal or state health care program conditions of participation, the property operator may be excluded from participating in those government health care programs.

Reimbursement

The reimbursement methodologies applied to health care facilities continue to evolve. Federal and state authorities have considered and implemented and may continue seeking to implement new or modified reimbursement methodologies, including value-based reimbursement methodologies that may negatively impact health care property operations. Likewise, third-party payors may continue imposing greater controls on operators, including through changes in reimbursement rates and fee structures. The impact of any such changes, if implemented, may result in a material adverse effect on our portfolio. No assurance can be given that current revenue sources or levels will be maintained. Accordingly, there can be no assurance that payments under a government health care program are currently, or will be in the future, sufficient to fully reimburse the property operators for their operating and capital expenses.

• Seniors Housing Facilities The majority of the revenues received by the operators of U.S. seniors housing facilities are from private pay sources. The remaining revenue source is primarily Medicaid provided under state waiver programs for home and community-based care. There can be no guarantee that a state Medicaid program operating pursuant to a waiver will be able to maintain its waiver status. Rates paid by self-pay residents are set by the facilities and are determined by local market conditions and operating costs. Generally, facilities receive a higher payment per day for a private pay resident than for a Medicaid beneficiary who requires a comparable level of care. The level of Medicaid reimbursement varies from state to state. Thus, the revenues generated by operators of our assisted living facilities may be adversely affected by payor mix, acuity level, or changes in Medicaid eligibility and reimbursement levels.

*•*Long-Term/Post-Acute Care Facilities The majority of the revenues received by the operators of these facilities are from the Medicare and Medicaid programs, with the balance representing reimbursement payments from private payors and patients. Consequently, changes in federal or state reimbursement policies may adversely affect an operator’s ability to cover its expenses, including our rent or debt service. Long-term/post-acute care facilities are subject to periodic pre- and post-payment reviews and other audits by federal and state authorities. A review or audit of a property operator’s claims could result in recoupments, denials or delay of payments in the future. Due to the significant judgments and estimates inherent in payor settlement accounting, no assurance can be given as to the adequacy of any reserves maintained by our property operators to cover potential adjustments to reimbursements or to cover settlements made to payors.

◦Medicare Reimbursement Generally, long-term/post-acute care facilities are reimbursed by Medicare under prospective payment systems, which generally provide reimbursement based upon a predetermined fixed amount per episode of care and are updated by CMS, an agency of the Department of Health and Human Services (“HHS”) annually. There is a risk under these payment systems that costs will exceed the fixed payments, or that payments may be set below the costs to provide certain items and services. Further, there is risk that Medicare Skilled Nursing Facility ("SNF") payment reforms may impact our tenants and operators. In addition, the HHS Office of Inspector General has released recommendations to address SNF billing practices and Medicare payment rates, which may impact our tenants and operators. In September 2022, HHS announced that additional data about the ownership of all Medicare-certified nursing homes will be released to the public. This information will make it easier for stakeholders (such as state licensing officials, state and federal law enforcement and researchers) and the public to identify common owners of nursing homes across different nursing home locations. The information will also allow for greater accessibility to information regarding facilities' performance and any common ownership links among facilities with poor performance. CMS announced it is increasing scrutiny and oversight over the country's poorest performing nursing facilities by strengthening requirements for completion of the Special Focus Facility Program and increasing enforcement actions against facilities that fail to demonstrate improvement, including denial of payment and potential loss of Medicare certification.

*◦*Medicaid Reimbursement Many states reimburse SNFs using fixed daily rates, which are applied prospectively based on patient acuity and the historical costs incurred in providing patient care. In most states, Medicaid does not fully reimburse the cost of providing services. Certain states are attempting to slow the rate of Medicaid growth by freezing rates or restricting eligibility and benefits. In addition, Medicaid reimbursement rates may decline if state revenues in a particular state are not sufficient to fund budgeted expenditures.

*•*Medicare Reimbursement for Physicians, Hospital Outpatient Departments (“HOPDs”), and Ambulatory Surgical Centers (“ASCs”) Changes in reimbursement to physicians, HOPDs and ASCs may further affect our tenants and operators. Generally, Medicare reimburses physicians under the Physician Fee Schedule, while HOPDs and ASCs are reimbursed under prospective payment systems. The Physician Fee Schedule and the HOPD and ASC prospective payment

systems are updated annually by CMS. These annual Medicare payment regulations have resulted in lower net pay increases than providers of those services have often expected. In addition, the Medicare and Children’s Health Insurance Program Reauthorization Act of 2015 (“MACRA”) includes payment reductions for providers who do not meet government quality standards. The implementation of pay-for-quality models like those required under MACRA has the potential to produce funding disparities that could adversely impact some provider tenants in outpatient medical buildings and other health care properties. Changes in Medicare Advantage plan payments may also indirectly affect our operators and tenants that contract with Medicare Advantage plans.

*•*Health Reform Laws The Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 (collectively, the “Health Reform Laws”) dramatically altered how health care is delivered and reimbursed in the U.S. and any substantial changes may directly impact us or the operators and tenants of our properties. Other health reform measures could be implemented as a result of political, legislative, regulatory and administrative developments and judicial proceedings. On February 28, 2022, President Biden announced reforms to be implemented by CMS to ensure that: (a) every nursing home provides a sufficient number of staff who are adequately trained to provide high-quality care; (b) poorly performing nursing homes are held accountable for improper and unsafe care and immediately improve their services or are cut off from taxpayer dollars; and (c) the public has better information about nursing home conditions so that they can find the best available options. These reforms include minimum staffing requirements, reinforced safeguards against unnecessary medications, more funding for inspection activities, increased scrutiny on poor performers and expanded financial penalties and other sanctions. We cannot predict whether the existing Health Reform Laws, or future health care reform legislation, executive order, or regulatory changes, will have a material impact on our operators’ or tenants’ property or business.

Fraud & Abuse Enforcement

Long-term/post-acute care facilities (and seniors housing facilities that receive Medicaid payments) are subject to federal, state, and local laws, regulations, and applicable guidance that govern the operations and financial and other arrangements that may be entered into by health care providers. Certain of these laws, such as the AKS and Stark Law, prohibit direct or indirect payments of any kind for the purpose of inducing or encouraging the referral of patients for medical products or services reimbursable by government health care programs. Other government health program laws require providers to furnish only medically necessary services and submit to the government valid and accurate statements for each service. Our operators and tenants that receive payments from federal health care programs, such as Medicare and Medicaid, are subject to substantial financial penalties under the Civil Monetary Penalties Act and the FCA upon a finding of noncompliance with such laws. In addition, states may also have separate false claims acts, which, among other things, generally prohibit health care providers from filing false claims or making false statements to receive payments. Federal and state FCAs contain "whistleblower" provisions that permit private individuals to bring health care fraud enforcement claims on behalf of the government. Still other laws require providers to comply with a variety of safety, health and other requirements relating to the condition of the licensed property and the quality of care provided. Sanctions for violations of these laws, regulations and other applicable guidance may include, but are not limited to, criminal and/or civil penalties and fines, loss of licensure, immediate termination of government payments, exclusion from any government health care program, damage assessments and imprisonment. In certain circumstances, violation of these rules (such as those prohibiting abusive and fraudulent behavior) with respect to one property may subject other facilities under common control or ownership to sanctions, including exclusion from participation in the Medicare and Medicaid programs, as well as other government health care programs, and revocation of healthcare licenses. In the ordinary course of its business, a property operator is regularly subjected to inquiries, investigations and audits by the federal and state agencies that oversee these laws and regulations.

Prosecutions, investigations or whistleblower actions could have a material adverse effect on a property operator’s liquidity, financial condition, and operations, which could adversely affect the ability of the operator to meet its financial obligations to us. In addition, government investigations and enforcement actions brought against the health care industry have increased dramatically over the past several years and are expected to continue. The costs for an operator of a health care property associated with both defending such enforcement actions and the undertakings in settling these actions can be substantial and could have a material adverse effect on the ability of an operator to meet its obligations to us. In addition, Welltower could potentially be directly subject to these health care fraud and abuse laws, as well as potential investigation or enforcement, as a result of our RIDEA-structured arrangements, and certain collaboration or other arrangements we may pursue with stakeholders who are directly subject to these laws.

Federal and State Data Privacy and Security Laws

The Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), as amended by the Health Information Technology for Economic and Clinical Health Act, and numerous other state and federal laws govern the collection, security, dissemination, use, access to and confidentiality of personal information, including individually identifiable health information. Violations of these laws may result in substantial civil and/or criminal fines and penalties. The costs to a business such as ours or to an operator of a health care property associated with developing and maintaining programs and systems to comply with data privacy and security laws, defending against privacy and security related claims or enforcement actions and

paying any assessed fines, can be substantial. Moreover, such costs could have a material adverse effect on the ability of an operator to meet its obligations to us. Finally, data privacy and security laws and regulations continue to develop, including with regard to HIPAA and U.S. state privacy laws. The California Consumer Privacy Act has been amended by the California Privacy Rights Act. These updates and the Virginia Consumer Data Protection Act went into effect January 1, 2023. Similar comprehensive privacy laws from Colorado, Connecticut and Utah will go into effect in 2023. As we use data to better inform our investments and the efficacy of care in our communities, these developments may add potential uncertainty and costs towards compliance obligations, business operations or transactions that depend on data. These new privacy laws may create restrictions or requirements in our, our operators' and other business partners' use, sharing and securing of data. New privacy and security laws could require substantial investment in resources to comply with regulatory changes as privacy and security laws proliferate in divergent ways or impose additional obligations, and potentially create new privacy related legal risks.

United Kingdom

In the U.K., care home services are principally regulated by the Health and Social Care Act 2008 (as amended) and other regulations. This legislation subjects service providers to a number of legally binding “Fundamental Standards” and requires, amongst other things, that all persons carrying out “Regulated Activities” in the U.K., and the managers of such persons, be registered. Providers of care home services are also subject (as data controllers) to laws governing their use of personal data (including in relation to their employees, clients and recipients of their services). These laws currently take the form of the U.K.’s Data Protection Act 2018 and the U.K. General Data Protection Regulation (collectively “U.K. DP Laws”). U.K. DP Laws impose a significant number of obligations on controllers with the potential for fines of up to 4% of annual worldwide turnover or £17.5 million, whichever is greater. Further, to the extent that an entity established in the U.K. or any other jurisdiction offers goods or services to individuals in the European Economic Area, that entity may also be subject to the E.U. General Data Protection Regulation ("E.U. GDPR"). Similarly, the E.U. GDPR imposes obligations on controllers with the potential for fines of up to 4% of annual worldwide turnover or €20 million, whichever is greater. Entities incorporated in or carrying on a business in the U.K., as well as individuals residing in the U.K., are also subject to the U.K. Bribery Act 2010. The U.K. has national minimum wage legislation with a maximum fine for non-payment of £20,000 per worker and employers who fail to pay will be banned from being a company director for up to 15 years. In addition, the Working Time and Holiday Pay Bill 2019-2021 is currently going through the U.K. Parliament, which makes provision for the expiration of the Working Time Regulations 1998, provides for additional regulations governing working time and makes provisions for holiday pay for employees.

Canada

Senior living residences in Canada are provincially regulated. Within each province, there are different categories for senior living residences that are generally based on the level of care sought and/or required by a resident (e.g. assisted or retirement living, senior living residences, residential care, long-term care). In some of these categories and depending on the province, residences may be government funded, or the individual residents may be eligible for a government subsidy, while other residences are exclusively private-pay. The governing legislation and regulations vary by province, but generally the object of the laws is to set licensing requirements and minimum standards for senior living residences, and regulate operations. These laws empower regulators in each province to take a variety of steps to ensure compliance, conduct inspections, issue reports and generally regulate the industry.

Our operations in Canada are subject to privacy legislation, including, in certain provinces, privacy laws specifically related to personal health information. Although the obligations of senior living residences in the various provinces differ, they all include the obligation to protect personal information. Under some of these laws, notification to the regulator in the event of an actual or suspected privacy breach is mandatory. The powers of privacy regulators and penalties for violations of privacy law vary according to the applicable law or are left to the courts. In September 2021, the province of Quebec adopted significant amendments to its privacy legislation, including a new enforcement scheme with significant penalties and fines: up to CAD $10 million or 2% of global turnover (whichever is greater) for administrative monetary penalties and up to CAD $25 million or 4% of global turnover for penal fines. The amendments will go into effect in three stages: (i) a few provisions on September 22, 2022, (ii) most provisions on September 22, 2023 (including the new enforcement scheme), and (iii) one provision on September 23, 2024. Senior living residences may also be subject to laws pertaining to residential tenancy, provincial and/or municipal laws applicable to fire safety, food services, zoning, occupational health and safety, public health and the provision of community health care and funded long-term/post-acute care.

Taxation

The following summary of the taxation of the Company and the material U.S. federal income tax consequences to the holders of the equity of the Company and the debt securities of the Company and Welltower OP (defined below) is for general information only and is not tax advice. This summary does not address all aspects of taxation that may be relevant to certain types of holders of stock or securities (including, but not limited to, insurance companies, tax-exempt entities, financial institutions or broker-dealers, persons holding shares of common stock as part of a hedging, integrated conversion, or constructive sale transaction or a straddle, traders in securities that use a mark-to-market method of accounting for their securities, investors in pass-through entities and non-U.S. corporations and persons who are not citizens or residents of the United States).

This summary does not discuss all of the aspects of U.S. federal income taxation that may be relevant to you in light of your particular investment or other circumstances. In addition, this summary does not discuss any state or local income taxation or non-U.S. income taxation or other non-U.S. tax consequences. This summary is based on current U.S. federal income tax laws. Subsequent developments in U.S. federal income tax law, including changes in law or differing interpretations, which may be applied retroactively, could have a material effect on the U.S. federal income tax consequences of purchasing, owning and disposing of our securities as set forth in this summary. Before you purchase our securities, you should consult your own tax advisor regarding the particular U.S. federal, state, local, non-U.S. and other tax consequences of acquiring, owning and selling our securities.

General

Prior to the Reorganization on April 1, 2022, whereby the Company’s predecessor, which had been known as Welltower Inc. until that date (“Old Welltower”), became a wholly owned subsidiary of WELL Merger Holdco Sub Inc. in a transaction intending to qualify as a reorganization under section 368(a)(1)(F) of the Internal Revenue Code of 1986, as amended (the “Code”). In connection with the Reorganization, Old Welltower changed its name to Welltower OP Inc., WELL Merger Holdco Sub Inc. changed its name to Welltower Inc. and Old Welltower became a “qualified REIT subsidiary” of the Company. Effective on May 24, 2022, Welltower OP Inc. converted from a Delaware corporation into a Delaware limited liability company named Welltower OP LLC (under both names, “Welltower OP”). Prior to the Reorganization, Old Welltower elected to be taxed as a REIT and was organized and operated in a manner intended to qualify as a REIT. As a result of the Reorganization, the Company is treated as a continuation of Old Welltower for U.S. federal income tax purposes and references in this summary to “the Company,” “us,” or “we” include references to Old Welltower unless otherwise specified or clearly required by the context.

We have been organized and operated in a manner intended to qualify as a REIT and we intend to continue to operate in such a manner as to qualify as a REIT, but there can be no assurance that we will qualify or remain qualified as a REIT. Qualification and taxation as a REIT depend upon our ability to meet a variety of qualification tests imposed under U.S. federal income tax law with respect to our income, assets, distributions and share ownership, as discussed below under “Qualification as a REIT.”

In any year in which we qualify as a REIT, in general, we will not be subject to U.S. federal income tax on that portion of our REIT taxable income or capital gain that is distributed to stockholders. We may, however, be subject to tax at normal corporate rates on any taxable income or capital gain not distributed. If we elect to retain and pay income tax on our net capital gain, stockholders would be taxed on their proportionate shares of our undistributed net capital gain and would receive a refundable credit for their shares of any taxes paid by us on such gain.

Despite qualifying as a REIT, we may be subject to U.S. federal income and excise tax as follows:

• To the extent that we do not distribute all of our net capital gain or distribute at least 90%, but less than 100%, of our “REIT taxable income,” as adjusted, we will be subject to tax on the undistributed amount at regular corporate tax rates;

• If we have net income from the sale or other disposition of “foreclosure property” that is held primarily for sale to customers in the ordinary course of business or other non-qualifying income from foreclosure property, such income will be taxed at the highest corporate rate;

• Any net income from prohibited transactions (which are, in general, sales or other dispositions of property held primarily for sale to customers in the ordinary course of business, other than dispositions of foreclosure property) will be subject to a 100% tax;

• If we fail to satisfy either the 75% or 95% gross income tests (as discussed below), but nonetheless maintain our qualification as a REIT because certain other requirements are met, we will be subject to a 100% tax on an amount equal to (1) the gross income attributable to the greater of (i) 75% of our gross income over the amount of qualifying gross income for purposes of the 75% gross income test (discussed below) or (ii) 95% of our gross income over the amount of qualifying gross income for purposes of the 95% gross income test (discussed below) multiplied by (2) a fraction intended to reflect our profitability;

• If we fail to distribute during each year at least the sum of (1) 85% of our REIT ordinary income for the year, (2) 95% of our REIT capital gain net income for such year (other than capital gain that we elect to retain and pay tax on) and (3) any undistributed taxable income from preceding periods, we will be subject to a 4% excise tax on the excess of such required distribution over amounts actually distributed; and

• We will be subject to a 100% tax on certain amounts from certain transactions involving our “taxable REIT subsidiaries” that are not conducted on an arm’s length basis. See “Investments in Taxable REIT Subsidiaries.”

We have acquired assets from “C” corporations in carryover basis transactions and may do so again in the future. A “C” corporation is generally defined as a corporation that is required to pay full corporate level U.S. federal income tax. If we recognize gain on the disposition of such assets during the five-year period beginning on the date on which the assets were acquired by us, then, to the extent of the assets’ “built-in gain” (e.g., the excess of the fair market value of the asset over the adjusted tax basis of the asset, in each case determined as of the beginning of the five-year period), we will be subject to tax on the gain at the highest regular corporate rate applicable. The results described in this paragraph with respect to the recognition of built-in gain assume that the “C” corporation did not make and was not treated as making an election to treat the built-in gain assets as sold to an unrelated party. For our assets that are subject to the built-in gains tax, the potential amount of built-in gains tax will be an additional factor when considering a possible sale of such assets within the five-year period beginning on the date on which the assets were acquired by us. See Note 19 to our consolidated financial statements for additional information regarding the built-in gains tax.

Qualification as a REIT

A REIT is defined as a corporation, trust or association:

(1) which is managed by one or more trustees or directors;

(2) the beneficial ownership of which is evidenced by transferable shares or by transferable certificates of beneficial interest;

(3) which would be taxable as a domestic corporation but for the U.S. federal income tax law relating to REITs;

(4) which is neither a financial institution nor an insurance company;

(5) the beneficial ownership of which is held by 100 or more persons in each taxable year of the REIT except for its first

taxable year;

(6) not more than 50% in value of the outstanding stock of which is owned during the last half of each taxable year, excluding its first taxable year, directly, indirectly or constructively, by or for five or fewer individuals (which includes certain entities) (the “Five or Fewer Requirement”); and

(7) which meets certain income and asset tests described below.

Conditions (1) to (4), inclusive, must be met during the entire taxable year and condition (5) must be met during at least 335 days of a taxable year of 12 months or during a proportionate part of a taxable year of less than 12 months. For purposes of condition (6), pension funds and certain other tax-exempt entities are treated as individuals, subject to a “look-through” exception in the case of certain pension funds.

Based on publicly available information, we believe we have satisfied the share ownership requirements set forth in (5) and (6) above. In addition, Article VI of our by-laws provides for restrictions regarding ownership and transfer of shares. These restrictions are intended to assist us in continuing to satisfy the share ownership requirements described in (5) and (6) above but may not ensure that we will, in all cases, be able to satisfy such requirements.

We have complied with, and will continue to comply with, tax regulatory rules to send annual letters to certain of our stockholders requesting information regarding the actual ownership of our stock. If, despite sending the annual letters, we do not know, or after exercising reasonable diligence would not have known, whether we failed to meet the Five or Fewer Requirement, we will be treated as having met the Five or Fewer Requirement. If we fail to comply with these tax regulatory rules, we will be subject to a monetary penalty. If our failure to comply were due to intentional disregard of the requirement, the penalty would be increased. However, if our failure to comply were due to reasonable cause and not willful neglect, no penalty would be imposed.

For purposes of the REIT income and asset tests our assets and income will include any asset owned and any income earned directly or indirectly through a disregarded entity, including a “qualified REIT subsidiary,” and a proportionate share of the assets of, and any income earned through, any entity we own that is treated as a partnership for U.S. federal income tax purposes, including Welltower OP. A corporation will qualify as a “qualified REIT subsidiary” if 100% of its stock is owned by a REIT, and the REIT does not elect to treat the subsidiary as a taxable REIT subsidiary.

We will own substantially all of our assets and earn substantially all of our income through Welltower OP and its direct or indirect subsidiaries. Prior to the LLC Conversion, Welltower OP was treated as a “qualified REIT subsidiary,” provided that we continue to qualify as a REIT. After the LLC Conversion, Welltower OP became a disregarded entity for U.S. federal income tax purposes until the admission of additional regarded members, at which time Welltower OP became a regarded entity treated as a partnership for U.S. federal income tax purposes.

Although we intend for any partnership in which we have acquired or will acquire an interest, directly or indirectly (a “Subsidiary Partnership”), to operate in a manner consistent with the requirements for our qualification as a REIT, we will be an indirect limited partner or non-managing member in some of the Subsidiary Partnerships. Though we nonetheless expect that

all such Subsidiary Partnerships will be required to operate in a manner consistent with the requirements for our qualification as a REIT, if a Subsidiary Partnership in which we own an interest but do not have control takes or expects to take actions that could jeopardize our status as a REIT or require us to pay tax, we may be forced to dispose of our interest in such entity. In addition, it is possible that a Subsidiary Partnership could take an action which could cause us to fail a gross income or asset test and that we would not become aware of such action in time for us to dispose of our interest in the Subsidiary Partnership or take other corrective action on a timely basis. In that case, we could fail to qualify as a REIT unless we were able to qualify for a statutory REIT “savings” provision, which could require us to pay a significant penalty tax to maintain our REIT qualification.

Income Tests There are two separate percentage tests relating to our sources of gross income that we must satisfy each taxable year:

• At least 75% of our gross income (excluding gross income from certain sales of property held primarily for sale) generally must be directly or indirectly derived each taxable year from “rents from real property,” dividends or other distributions on, and gain (other than gain from prohibited transactions) from the sale or other disposition of, REIT shares, mortgages on real property, other income from investments relating to real property or certain income from qualified temporary investments (the “75% gross income test”).

• At least 95% of our gross income (excluding gross income from certain sales of property held primarily for sale) generally must be directly or indirectly derived each taxable year from any of the sources qualifying for the 75% gross income test and from dividends (including dividends from taxable REIT subsidiaries) and interest (the “95% gross income test”).

Income from hedging and non-U.S. currency transactions is excluded from the 95% and 75% gross income tests if certain requirements are met but otherwise will constitute gross income which does not qualify under the 95% or 75% gross income tests.

Rents received by us will qualify as “rents from real property” for purposes of satisfying the gross income tests for a REIT only if several conditions are met:

• The amount of rent must not be based in whole or in part on the income or profits of any person, although rents generally will not be excluded merely because they are based on a fixed percentage or percentages of receipts or sales.

• Rents received from a tenant will not qualify as rents from real property if the REIT, or an owner of 10% or more of the REIT, directly or constructively owns 10% or more of the tenant, unless the tenant is our taxable REIT subsidiary and certain other requirements are met with respect to the real property being rented.

• If rent attributable to personal property leased in connection with a lease of real property is greater than 15% of the total rent received under the lease, then the portion of rent attributable to such personal property will not qualify as “rents from real property.”

• For rents to qualify as rents from real property, we generally must not furnish or render services to tenants, other than through a taxable REIT subsidiary or an “independent contractor” from whom we derive no income, except that we may directly provide services that are usually or customarily rendered in the geographic area in which the property is located in connection with the rental of real property for occupancy only or are not otherwise considered rendered to the occupant for the occupant’s convenience.

• We may lease “qualified health care properties” on an arm’s-length basis to a taxable REIT subsidiary if the property is operated on behalf of such subsidiary by a person that qualifies as an “independent contractor” and that is, or is related to a person that is, actively engaged in the trade or business of operating health care facilities for any person unrelated to us or our taxable REIT subsidiary (such person, an “eligible independent contractor”). If this is the case, the rent that the REIT receives from the taxable REIT subsidiary generally will be treated as “rents from real property.” A “qualified health care property” includes any real property and any personal property that is, or is necessary or incidental to the use of, a hospital, nursing facility, assisted living facility, congregate care facility, qualified continuing care facility, or other licensed facility that extends medical or nursing or ancillary services to patients and is operated by a provider of such services that is eligible for participation in the Medicare program with respect to such facility.

A REIT is permitted to render a de minimis amount of impermissible services to tenants of a property and still treat amounts received with respect to that property as rent from real property. The amount received or accrued by the REIT during the taxable year for the impermissible services with respect to a property may not exceed 1% of all amounts received or accrued by the REIT directly or indirectly from the property. The amount received for any service or management operation for this purpose shall be deemed to be not less than 150% of the direct cost of the REIT in furnishing or rendering the service or providing the management or operation. Furthermore, impermissible services may be furnished to tenants by a taxable REIT subsidiary subject to certain conditions, which would permit us to still treat rents received with respect to the property as rent from real property.

The term “interest” generally does not include any amount if the determination of the amount depends in whole or in part on the income or profits of any person, although an amount generally will not be excluded from the term “interest” solely by reason of being based on a fixed percentage of receipts or sales or by reason of being based on the income or profits of a debtor which derives substantially all of its income with respect to the property securing such debt from the leasing of substantially all of such property to tenants, to the extent that the rents paid by the tenants would qualify as rents from real property if the Company earned such amounts directly.

If we fail to satisfy one or both of the 75% or 95% gross income tests for any taxable year, we may nevertheless qualify as a REIT for such year if we are eligible for certain relief provisions provided by the Internal Revenue Code. These relief provisions generally will be available if (1) following our identification of the failure, we file a schedule for such taxable year describing each item of our gross income, and (2) the failure to meet such tests was due to reasonable cause and not due to willful neglect. It is not now possible to determine the circumstances under which we may be entitled to the benefit of these relief provisions. If these relief provisions apply, a 100% tax is imposed on an amount equal to (1) the gross income attributable to (i) 75% of our gross income over the amount of qualifying gross income for purposes of the 75% gross income test and (ii) 95% of our gross income over the amount of qualifying gross income for purposes of the 95% gross income test, multiplied by (2) a fraction intended to reflect our profitability. The Secretary of the Treasury is given broad authority to determine whether particular items of income or gain qualify under the 75% and 95% gross income tests and to exclude items from the measure of gross income for such purposes.

Asset Tests Within 30 days after the close of each quarter of our taxable year, we must also satisfy several tests relating to the nature and diversification of our assets determined in accordance with generally accepted accounting principles. At least 75% of the value of our total assets must be represented by real estate assets (including interests in real property, interests in mortgages on real property or on interests in real property, shares in other REITs and debt instruments issued by publicly offered REITs), cash, cash items (including receivables arising in the ordinary course of our operation), government securities and qualified temporary investments (the “75% asset test”). Although the remaining 25% of our assets generally may be invested without restriction, we are prohibited from owning securities representing more than 10% of either the vote (the “10% vote test”) or value (the “10% value test”) of the outstanding securities of any issuer other than another REIT or a taxable REIT subsidiary. Further, no more than 20% of our total assets may be represented by securities of one or more taxable REIT subsidiaries (the “20% asset test”) and no more than 5% of the value of our total assets may be represented by securities of any non-governmental issuer other than a qualified REIT subsidiary (the “5% asset test”), another REIT or a taxable REIT subsidiary. Each of the 10% vote test, the 10% value test and the 20% and 5% asset tests must be satisfied at the end of each quarter. There are special rules which provide relief if the value-related tests are not satisfied due to changes in the value of the assets of a REIT.

Certain items are excluded from the 10% value test, including: (1) straight debt securities meeting certain requirements; (2) any loan to an individual or an estate; (3) any rental agreement described in Section 467 of the Internal Revenue Code, other than with a “related person”; (4) any obligation to pay rents from real property; (5) certain securities issued by a state or any subdivision thereof, the District of Columbia, a non-U.S. government, or any political subdivision thereof, or the Commonwealth of Puerto Rico; (6) any security issued by a REIT; and (7) any other arrangement that, as determined by the Secretary of the Treasury, is excepted from the definition of security (“10% Value Excluded Securities”). If a REIT, or its taxable REIT subsidiary, holds (1) straight debt securities of a corporate or partnership issuer and (2) securities of such issuer that are not 10% Value Excluded Securities and have an aggregate value greater than 1% of such issuer’s outstanding securities, the straight debt securities will be included in the 10% value test.

A REIT’s interest as a partner in a partnership is not treated as a security for purposes of applying the 10% value test to securities issued by the partnership. Further, any debt instrument issued by a partnership that is not a 10% Value Excluded Security will not be a security for purposes of applying the 10% value test (1) to the extent of the REIT’s interest as a partner in the partnership or (2) if at least 75% of the partnership’s gross income (excluding gross income from prohibited transactions) would qualify for the 75% gross income test. For purposes of the 10% value test, a REIT’s interest in a partnership’s assets is determined by the REIT’s proportionate interest in any securities issued by the partnership (other than the excluded securities described in the preceding paragraph).

If a REIT or its “qualified business unit” uses a non-U.S. currency as its functional currency, the term “cash” includes such non-U.S. currency, but only to the extent such non-U.S. currency is (i) held for use in the normal course of the activities of the REIT or “qualified business unit” which give rise to items of income or gain that are included in the 95% and 75% gross income tests or are directly related to acquiring or holding assets qualifying under the 75% asset test, and (ii) not held in connection with dealing or engaging in substantial and regular trading in securities.

With respect to corrections of failures as to violations of the 10% vote test, the 10% value test or the 5% asset test, a REIT may avoid disqualification as a REIT by disposing of sufficient assets to cure a violation due to the ownership of assets that do not exceed the lesser of 1% of the REIT’s assets at the end of the relevant quarter or $10,000,000, provided that the disposition occurs within six months following the last day of the quarter in which the REIT first identified the violation. For violations of any of the REIT asset tests due to reasonable cause and not willful neglect that exceed the thresholds described in the preceding

sentence, a REIT can avoid disqualification as a REIT after the close of a taxable quarter by taking certain steps, including disposition of sufficient assets within the six month period described above to meet the applicable asset test, paying a tax equal to the greater of $50,000 or the highest corporate tax rate multiplied by the net income generated by the non-qualifying assets during the period of time that the assets were held as non-qualifying assets and filing a schedule with the Internal Revenue Service that describes the non-qualifying assets.

Investments in Taxable REIT Subsidiaries REITs may own more than 10% of the voting power and value of securities in taxable REIT subsidiaries. Unlike a qualified REIT subsidiary, other disregarded entity or partnership, the income and assets of a taxable REIT subsidiary are not attributable to the REIT for purposes of satisfying the income and asset ownership requirements applicable to REIT qualification. We and any taxable corporate entity in which we own an interest, directly or indirectly, are allowed to jointly elect to treat such entity as a “taxable REIT subsidiary.”

Certain of our subsidiaries have elected or will elect taxable REIT subsidiary status. Taxable REIT subsidiaries are subject to full corporate level U.S. federal taxation on their earnings but are permitted to engage in certain types of activities that cannot be performed directly by REITs without jeopardizing the REIT status of their parent REIT. The taxes to which our taxable REIT subsidiaries are subject will reduce the cash available for such taxable REIT subsidiaries to distribute as dividends to us.

The Internal Revenue Service may redetermine amounts from transactions between a REIT and its taxable REIT subsidiary where there is a lack of arm’s-length dealing between the parties. Any taxable income allocated to, or deductible expenses allocated away, from a taxable REIT subsidiary would increase its tax liability. Further, certain amounts from certain transactions involving a REIT and its taxable REIT subsidiaries could be subject to a 100% tax if not conducted on an arm’s length basis.

A taxable REIT subsidiary does not include any corporation that directly or indirectly operates or manages a lodging facility or a health care facility unless such facility is operated on behalf of such subsidiary by a person that is an independent contractor and certain other requirements are met. The failure of a subsidiary of ours to qualify as a taxable REIT subsidiary as a result of operating a lodging facility or a health care facility could have an adverse effect on the Company’s ability to comply with the REIT income and asset tests, and thus could impair the Company’s ability to qualify as a REIT unless the Company could avail itself of certain relief provisions under the Code.

For tax years beginning after December 31, 2022, the Inflation Reduction Act of 2022 (“IRA”) imposes among other things, a 15% Corporate Alternative Minimum Tax (“Corporate AMT”) on certain U.S. corporations with average adjusted financial statement income in excess of $1 billion. Although, by its terms, the Corporate AMT is not applicable to REITs, it is not certain whether or how the Corporate AMT would apply to our TRSs.

In December 2022, Treasury issued Notice 2023-7, indicating its intention to propose regulations and provide other guidance regarding the Corporate AMT and issuing certain interim rules on which taxpayers may rely. Until further regulations and guidance from the IRS and Treasury are released, the impact of the Corporate AMT on our TRSs is uncertain and it is possible that our taxable REIT subsidiaries will be subject to material U.S. federal income taxes under the Corporate AMT.

Investments in REIT Subsidiaries The Company, through Welltower OP, owns and may acquire direct or indirect interests in one or more entities that have elected or will elect to be taxed as REITs under the Code (each, a “Subsidiary REIT”). A Subsidiary REIT is subject to the various REIT qualification requirements and other limitations described herein that are applicable to the Company. If a Subsidiary REIT were to fail to qualify as a REIT, then (i) that Subsidiary REIT would become subject to U.S. federal income tax and (ii) the Subsidiary REIT’s failure to qualify could have an adverse effect on the Company’s ability to comply with the REIT income and asset tests, and thus could impair the Company’s ability to qualify as a REIT unless the Company could avail itself of certain relief provisions under the Code.

Annual Distribution Requirements In order to avoid being taxed as a regular corporation, we are required to make distributions (other than capital gain distributions) to our stockholders which qualify for the dividends paid deduction in an amount at least equal to (1) the sum of (i) 90% of our “REIT taxable income” (computed without regard to the dividends paid deduction and our net capital gain) and (ii) 90% of the after-tax net income, if any, from foreclosure property, minus (2) a portion of certain items of non-cash income. These distributions must be paid in the taxable year to which they relate, or in the following taxable year if declared before we timely file our tax return for that year and if paid on or before the first regular distribution payment after such declaration. Prior to 2014, with respect to all REITs the amount distributed could not be preferential. This means that every stockholder of the class of stock to which a distribution is made must be treated the same as every other stockholder of that class, and no class of stock may be treated otherwise than in accordance with its dividend rights as a class (the “preferential dividend rule”). The preferential dividend rule no longer applies to publicly offered REITs, however, the rule is still applicable to REITs which are not publicly offered, which would include several of our Subsidiary REITs. To the extent that we do not distribute all of our net capital gain or distribute at least 90%, but less than 100%, of our “REIT taxable income,” as adjusted, we will be subject to tax on the undistributed amount at regular corporate tax rates. As discussed above, we may be subject to an excise tax if we fail to meet certain other distribution requirements. Although we intend to make timely distributions sufficient to satisfy these annual distribution requirements for subsequent years, economic, market, legal, tax or other factors could limit our ability to meet those requirements.

It is also possible that, from time to time, we may not have sufficient cash or other liquid assets to meet the 90% distribution requirement, or to distribute such greater amount as may be necessary to avoid income and excise taxation, due to, among other things, (1) timing differences between (i) cash receipts and cash expenditures and (ii) the inclusion of income and deduction of expenses in arriving at our taxable income, or (2) the payment of expenditures that may not be deductible to us. In the event that timing differences occur, we may find it necessary to arrange for borrowings or, if possible, pay dividends in the form of taxable stock dividends in order to meet the distribution requirement.

Under certain circumstances, including in the event of a deficiency determined by the Internal Revenue Service, we may be able to rectify a resulting failure to meet the distribution requirement for a year by paying “deficiency dividends” to stockholders in a later year, which may be included in our deduction for distributions paid for the earlier year. Thus, we may be able to avoid being disqualified as a REIT and/or taxed on amounts distributed as deficiency dividends; however, we will be required to pay applicable penalties and interest based upon the amount of any deduction taken for deficiency dividend distributions.

Failure to Qualify as a REIT If we fail to qualify for taxation as a REIT in any taxable year, we will be subject to U.S. federal income tax on our taxable income at regular corporate rates. Distributions to stockholders in any year in which we fail to qualify as a REIT will not be deductible by us. As a result, we anticipate that our failure to qualify as a REIT would reduce the cash available for distribution by us to our stockholders. In addition, if we fail to qualify as a REIT, we will not be required to distribute any amounts to our stockholders, and all distributions to stockholders will be taxable as regular corporate dividends to the extent of our current and accumulated earnings and profits. In such event, corporate stockholders may be eligible for the dividends-received deduction. In addition, non-corporate stockholders, including individuals, may be eligible for the preferential tax rates on qualified dividend income. Non-corporate stockholders, including individuals, generally may deduct up to 20% of dividends from a REIT, other than capital gain dividends and dividends treated as qualified dividend income, for taxable years beginning before January 1, 2026 for purposes of determining their U.S. federal income tax, subject to certain holding period requirements and other limitations. If we fail to qualify as a REIT, such stockholders may not claim this deduction with respect to dividends paid by us. Unless entitled to relief under specific statutory provisions, we also will be disqualified from taxation as a REIT for the four taxable years following the year during which qualification was lost. It is not possible to state whether in all circumstances we would be entitled to statutory relief. Failure to qualify for even one year could result in our need to incur indebtedness or liquidate investments in order to pay potentially significant resulting tax liabilities.

In addition to the relief described above under “Income Tests” and “Asset Tests,” statutory relief is available in the event that we violate a provision of the Internal Revenue Code that would result in our failure to qualify as a REIT if: (1) the violation is due to reasonable cause and not due to willful neglect; (2) we pay a penalty of $50,000 for each failure to satisfy the provision; and (3) the violation does not include a violation described under “Income Tests” or “Asset Tests” above. It is not now possible to determine the circumstances under which we may be entitled to the benefit of these relief provisions.

Material U.S. Federal Income Tax Consequences to Holders of Our Stock and the Debt Securities of the Company and Welltower OP

The following discussion is a summary of the material U.S. federal income tax consequences to you of acquiring, owning and disposing of stock of the Company or debt securities of the Company or Welltower OP. This discussion is limited to holders who hold stock of the Company or debt securities of the Company or Welltower OP as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances, including the alternative minimum tax. In addition, except where specifically noted, it does not address consequences relevant to holders subject to special rules, including, without limitation:

• U.S. expatriates and former citizens or long-term residents of the United States;

• U.S. holders (as defined below) whose functional currency is not the U.S. dollar;

• persons holding stock or debt securities as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment;

• banks, insurance companies, and other financial institutions;

• REITs or regulated investment companies;

• brokers, dealers or traders in securities;

• “controlled foreign corporations,” “passive foreign investment companies,” and corporations that accumulate earnings to avoid U.S. federal income tax;

• S corporations, partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes (and investors therein);

• tax-exempt organizations or governmental organizations;

• persons subject to special tax accounting rules as a result of any item of gross income with respect to stock or debt securities being taken into account in an applicable financial statement;

• persons deemed to sell stock or debt securities under the constructive sale provisions of the Code; and

• persons who hold or receive our stock pursuant to the exercise of any employee stock option or otherwise as compensation.

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT INTENDED AS TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF OUR STOCK OR DEBT SECURITIES ARISING UNDER OTHER U.S. FEDERAL TAX LAWS (INCLUDING ESTATE AND GIFT TAX LAWS), UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

For purposes of this discussion, a “U.S. holder” is a beneficial owner of stock of the Company or debt securities of the Company or Welltower OP that, for U.S. federal income tax purposes, is or is treated as:

• an individual who is a citizen or resident of the United States;

• an entity classified as a corporation created or organized under the laws of the United States, any state thereof or the District of Columbia;

• an estate the income of which is subject to U.S. federal income tax regardless of its source; or

• a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code) or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

For purposes of this discussion, a “non-U.S. holder” is any beneficial owner of our stock or debt securities that is neither a U.S. holder nor an entity treated as a partnership for U.S. federal income tax purposes.

If an entity treated as a partnership for U.S. federal income tax purposes holds our stock or debt securities, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding stock of the Company or debt securities of the Company or Welltower OP and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

Taxation of Taxable U.S. Holders of Our Stock

Distributions Generally Distributions out of our current or accumulated earnings and profits will be treated as dividends and, other than with respect to capital gain dividends and certain amounts which have previously been subject to corporate level tax, as discussed below, will be taxable to our taxable U.S. holders as ordinary income when actually or constructively received. See “Tax Rates” below. As long as we qualify as a REIT, these distributions will not be eligible for the dividends-received deduction in the case of U.S. holders that are corporations or, except to the extent described in “Tax Rates” below, the preferential rates on qualified dividend income applicable to non-corporate U.S. holders, including individuals. For purposes of determining whether distributions to holders of our stock are out of our current or accumulated earnings and profits, our earnings and profits will be allocated first to our outstanding preferred stock, if any, and then to our outstanding common stock.

To the extent that we make distributions on our stock in excess of our current and accumulated earnings and profits allocable to such stock, these distributions will be treated first as a tax-free return of capital to a U.S. holder to the extent of the U.S. holder’s adjusted tax basis in such shares of stock. This treatment will reduce the U.S. holder’s adjusted tax basis in such shares of stock by such amount, but not below zero. Distributions in excess of our current and accumulated earnings and profits and in excess of a U.S. holder’s adjusted tax basis in its shares will be taxable as capital gain. Such gain will be taxable as long-term capital gain if the shares have been held for more than one year. Dividends we declare in October, November, or December of any year and which are payable to a holder of record on a specified date in any of these months will be treated as both paid by us and received by the holder on December 31 of that year, provided we actually pay the dividend on or before January 31 of the following year. U.S. holders may not include in their own income tax returns any of our net operating losses or capital losses.

U.S. holders that receive taxable stock distributions, including distributions partially payable in our common stock and partially payable in cash, would be required to include the full amount of the distribution (i.e., the cash and the stock portion) as a dividend (subject to limited exceptions) to the extent of our current and accumulated earnings and profits for U.S. federal income tax purposes, as described above. The amount of any distribution payable in our common stock generally is equal to the amount of cash that could have been received instead of the common stock. Depending on the circumstances of a U.S. holder, the tax on the distribution may exceed the amount of the distribution received in cash, in which case such U.S. holder would

have to pay the tax using cash from other sources. If a U.S. holder sells the common stock it received in connection with a taxable stock distribution in order to pay this tax and the proceeds of such sale are less than the amount required to be included in income with respect to the stock portion of the distribution, such U.S. holder could have a capital loss with respect to the stock sale that could not be used to offset such income. A U.S. holder that receives common stock pursuant to such distribution generally has a tax basis in such common stock equal to the amount of cash that could have been received instead of such common stock as described above, and has a holding period in such common stock that begins on the day immediately following the payment date for the distribution.

Capital Gain Dividends Dividends that we properly designate as capital gain dividends will be taxable to our taxable U.S. holders as a gain from the sale or disposition of a capital asset held for more than one year, to the extent that such gain does not exceed our actual net capital gain for the taxable year. U.S. holders that are corporations may, however, be required to treat up to 20% of certain capital gain dividends as ordinary income.

Retention of Net Capital Gains We may elect to retain, rather than distribute as a capital gain dividend, all or a portion of our net capital gains. If we make this election, we would pay tax on our retained net capital gains. In addition, to the extent we so elect, our earnings and profits (determined for U.S. federal income tax purposes) would be adjusted accordingly, and a U.S. holder generally would:

• include its pro rata share of our undistributed capital gain in computing its long-term capital gains in its U.S. federal income tax return for its taxable year in which the last day of our taxable year falls, subject to certain limitations as to the amount that is includable;

• be deemed to have paid its share of the capital gains tax imposed on us on the designated amounts included in the U.S. holder’s income as long-term capital gain;

• receive a credit or refund for the amount of tax deemed paid by it; and

• increase the adjusted tax basis of its stock by the difference between the amount of includable gains and the tax deemed to have been paid by it.

In addition, a U.S. holder that is a corporation is required to appropriately adjust its earnings and profits for the retained capital gains in accordance with Treasury Regulations. These Treasury Regulations have not yet been promulgated so the appropriate method for making such adjustment is unclear.

Passive Activity Losses and Investment Interest Limitations Distributions we make and gain arising from the sale or exchange of our stock by a U.S. holder will not be treated as passive activity income. As a result, U.S. holders generally will not be able to apply any “passive losses” against this income or gain. A U.S. holder generally may elect to treat capital gain dividends, capital gains from the disposition of our stock and income designated as qualified dividend income, as described in “Tax Rates” below, as investment income for purposes of computing the investment interest limitation, but in such case, the holder will be taxed at ordinary income rates on such amount. Other distributions made by us, to the extent they do not constitute a return of capital, generally will be treated as investment income for purposes of computing the investment interest limitation.

Dispositions of Our Stock Except as described below under “Redemption or Repurchase by Us,” if a U.S. holder sells or disposes of shares of our stock, it will recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference between the amount of cash and the fair market value of any property received on the sale or other disposition of the shares and the holder’s adjusted tax basis in the shares. This gain or loss, except as provided below, will be long-term capital gain or loss if the holder has held such stock for more than one year. However, if a U.S. holder recognizes a loss upon the sale or other disposition of stock that it has held for six months or less, after applying certain holding period rules, the loss recognized will be treated as a long-term capital loss to the extent the U.S. holder received distributions from us which were required to be treated as long-term capital gains. The deductibility of capital losses is subject to limitations.

Redemption or Repurchase by Us A redemption or repurchase of shares of our stock will be treated under Section 302 of the Code as a distribution (and taxable as a dividend to the extent of our current and accumulated earnings and profits as described above under “Distributions Generally”) unless the redemption or repurchase satisfies one of the tests set forth in Section 302(b) of the Code and is therefore treated as a sale or exchange of the redeemed or repurchased shares. The redemption or repurchase generally will be treated as a sale or exchange if it:

• is “substantially disproportionate” with respect to the U.S. holder,

• results in a “complete redemption” of the U.S. holder’s stock interest in us, or

• is “not essentially equivalent to a dividend” with respect to the U.S. holder,

all within the meaning of Section 302(b) of the Code.

In determining whether any of these tests has been met, shares of our stock, including common stock and other equity interests in us, considered to be owned by the U.S. holder by reason of certain constructive ownership rules set forth in the Code, as well as shares of our stock actually owned by the U.S. holder, generally must be taken into account. Because the determination as to whether any of the alternative tests of Section 302(b) of the Code will be satisfied with respect to the U.S. holder depends upon the facts and circumstances at the time that the determination must be made, U.S. holders are advised to consult their tax advisors to determine such tax treatment.

If a redemption or repurchase of shares of our stock is treated as a distribution, the amount of the distribution will be measured by the amount of cash and the fair market value of any property received. See “Distributions Generally.” A U.S. holder’s adjusted tax basis in the redeemed or repurchased shares generally will be transferred to the holder’s remaining shares of our stock, if any. If a U.S. holder owns no other shares of our stock, under certain circumstances, such basis may be transferred to a related person or it may be lost entirely. Prospective investors should consult their tax advisors regarding the U.S. federal income tax consequences of a redemption or repurchase of our stock.

If a redemption or repurchase of shares of our stock is not treated as a distribution, it will be treated as a taxable sale or exchange in the manner described under “Dispositions of Our Stock.”

Tax Rates Currently, the maximum tax rate for non-corporate taxpayers for (1) long-term capital gains, including certain “capital gain dividends,” generally is 20% (although depending on the characteristics of the assets which produced these gains and on designations which we may make, certain capital gain dividends may be taxed at a 25% rate) and (2) “qualified dividend income” generally is 20%. In general, dividends payable by REITs are not eligible for the reduced tax rate applicable to qualified dividend income, except to the extent that certain holding period requirements have been met and the REIT’s dividends are attributable to dividends received from taxable corporations (such as its taxable REIT subsidiaries) or to income that was subject to tax at the corporate/REIT level (for example, if the REIT distributed taxable income that it retained and paid tax on in the prior taxable year). Capital gain dividends will only be eligible for the rates described above to the extent that they are properly designated by us as “capital gain dividends.” As mentioned above, U.S. holders that are corporations may be required to treat up to 20% of some capital gain dividends as ordinary income. In addition, non-corporate U.S. holders, including individuals, generally may deduct up to 20% of dividends from a REIT, other than capital gain dividends and dividends treated as qualified dividend income, for taxable years beginning before January 1, 2026 for purposes of determining their U.S. federal income tax (but not for purposes of the 3.8% Medicare tax), subject to certain holding period requirements and other limitations.

Taxation of Tax-Exempt U.S. Holders of Our Stock

Dividend income from us and gain arising upon a sale of shares of our stock generally should not be unrelated business taxable income (“UBTI”) to a tax-exempt U.S. holder, except as described below. This income or gain will be UBTI, however, to the extent a tax-exempt U.S. holder holds its shares as “debt-financed property” within the meaning of the Code. Generally, “debt-financed property” is property the acquisition or holding of which was financed through a borrowing by the tax-exempt holder.

For tax-exempt U.S. holders that are social clubs, voluntary employee benefit associations or supplemental unemployment benefit trusts exempt from U.S. federal income taxation under Sections 501(c)(7), (c)(9) or (c)(17) of the Code, respectively, income from an investment in our shares will constitute UBTI unless the organization is able to properly claim a deduction for amounts set aside or placed in reserve for specific purposes so as to offset the income generated by its investment in our shares. These prospective investors should consult their tax advisors concerning these “set aside” and reserve requirements.

Notwithstanding the above, however, a portion of the dividends paid by a “pension-held REIT” may be treated as UBTI as to certain trusts that hold more than 10%, by value, of the interests in the REIT. A REIT will not be a “pension-held REIT” if it is able to satisfy the “not closely held” requirement without relying on the “look-through” exception with respect to certain trusts or if such REIT is not “predominantly held” by “qualified trusts.” As a result of restrictions on ownership and transfer of our stock contained in our charter, we do not expect to be classified as a “pension-held REIT,” and as a result, the tax treatment described above should be inapplicable to our holders. However, because our common stock is (and, we anticipate, will continue to be) publicly traded, we cannot guarantee that this will always be the case.

Taxation of Non-U.S. Holders of Our Stock

The following discussion addresses the rules governing U.S. federal income taxation of the acquisition, ownership and disposition of our stock by non-U.S. holders. These rules are complex, and no attempt is made herein to provide more than a brief summary of such rules. Accordingly, the discussion does not address all aspects of U.S. federal income taxation and does not address other federal, state, local or non-U.S. tax consequences that may be relevant to a non-U.S. holder in light of its particular circumstances. We urge non-U.S. holders to consult their tax advisors to determine the impact of U.S. federal, state, local and non-U.S. income and other tax laws and any applicable tax treaty on the acquisition, ownership and disposition of shares of our stock, including any reporting requirements.

Distributions Generally Distributions (including any taxable stock distributions) that are neither attributable to gains from sales or exchanges by us of United States real property interests (“USRPIs”) nor designated by us as capital gain dividends (except as described below) will be treated as dividends of ordinary income to the extent that they are made out of our current or accumulated earnings and profits. Such distributions ordinarily will be subject to withholding of U.S. federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty, unless the distributions are treated as effectively connected with the conduct by the non-U.S. holder of a trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment in the United States to which such

dividends are attributable). Under certain treaties, however, lower withholding rates generally applicable to dividends do not apply to dividends from a REIT. Certain certification and disclosure requirements must be satisfied for a non-U.S. holder to be exempt from withholding under the effectively connected income exemption. Dividends that are treated as effectively connected with a U.S. trade or business generally will not be subject to withholding but will be subject to U.S. federal income tax on a net basis in the same manner as dividends paid to U.S. holders are subject to U.S. federal income tax. Any such dividends received by a non-U.S. holder that is a corporation may also be subject to an additional branch profits tax at a 30% rate (applicable after deducting U.S. federal income taxes paid on such effectively connected income) or such lower rate as may be specified by an applicable income tax treaty.

Except as otherwise provided below, we expect to withhold U.S. federal income tax at the rate of 30% on any distributions made to a non-U.S. holder unless:

(1) a lower treaty rate applies and the non-U.S. holder furnishes an Internal Revenue Service Form W-8BEN or W-8BEN-E (or other applicable documentation) evidencing eligibility for that reduced treaty rate; or

(2) the non-U.S. holder furnishes an Internal Revenue Service Form W-8ECI (or other applicable documentation) claiming that the distribution is income effectively connected with the non-U.S. holder’s trade or business.

Distributions in excess of our current and accumulated earnings and profits will not be taxable to a non-U.S. holder to the extent that such distributions do not exceed the adjusted tax basis of the holder’s stock, but rather will reduce the adjusted tax basis of such stock. To the extent that such distributions exceed the non-U.S. holder’s adjusted tax basis in such stock, they generally will give rise to gain from the sale or exchange of such stock, the tax treatment of which is described below. However, such excess distributions may be treated as dividend income for certain non-U.S. holders. For withholding purposes, we expect to treat all distributions as made out of our current or accumulated earnings and profits. However, amounts withheld may be refundable if it is subsequently determined that the distribution was, in fact, in excess of our current and accumulated earnings and profits, provided that certain conditions are met.

Capital Gain Dividends and Distributions Attributable to a Sale or Exchange of United States Real Property Interests Distributions to a non-U.S. holder that we properly designate as capital gain dividends, other than those arising from the disposition of a USRPI, generally should not be subject to U.S. federal income taxation, unless:

(1) the investment in our stock is treated as effectively connected with the conduct by the non-U.S. holder of a trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment in the United States to which such dividends are attributable), in which case the non-U.S. holder will be subject to the same treatment as U.S. holders with respect to such gain, except that a non-U.S. holder that is a corporation may also be subject to a branch profits tax of up to 30%, as discussed above; or

(2) the non-U.S. holder is a nonresident alien individual who is present in the United States for 183 days or more during the taxable year and certain other conditions are met, in which case the non-U.S. holder will be subject to U.S. federal income tax at a rate of 30% on the non-U.S. holder’s capital gains (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of such non-U.S. holder (even though the individual is not considered a resident of the United States), provided the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

Pursuant to the Foreign Investment in Real Property Tax Act, which is referred to as “FIRPTA,” distributions to a non-U.S. holder that are attributable to gain from sales or exchanges by us of USRPIs, whether or not designated as capital gain dividends, will cause the non-U.S. holder to be treated as recognizing such gain as income effectively connected with a U.S. trade or business. Non-U.S. holders generally would be taxed at the regular rates applicable to U.S. holders, subject to any applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals. We also will be required to withhold and to remit to the Internal Revenue Service 21% of any distribution to non-U.S. holders attributable to gain from sales or exchanges by us of USRPIs. Distributions subject to FIRPTA may also be subject to a 30% branch profits tax in the hands of a non-U.S. holder that is a corporation. The amount withheld is creditable against the non-U.S. holder’s U.S. federal income tax liability. However, any distribution with respect to any class of stock that is “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market located in the United States is not subject to FIRPTA, and therefore, not subject to the 21% U.S. withholding tax described above, if the non-U.S. holder did not own more than 10% of such class of stock at any time during the one-year period ending on the date of the distribution. Instead, such distributions generally will be treated as ordinary dividend distributions and subject to withholding in the manner described above with respect to ordinary dividends. Furthermore, distributions to “qualified foreign pension funds” or entities all of the interests of which are held by “qualified pension funds” are exempt from FIRPTA. Non-U.S. holders should consult their tax advisors regarding the application of these rules.

Retention of Net Capital Gains Although the law is not clear on the matter, it appears that amounts we designate as retained net capital gains in respect of our stock should be treated with respect to non-U.S. holders as actual distributions of capital gain dividends. Under this approach, the non-U.S. holders may be able to offset as a credit against their U.S. federal income tax liability their proportionate share of the tax paid by us on such retained net capital gains and to receive from the Internal

Revenue Service a refund to the extent their proportionate share of such tax paid by us exceeds their actual U.S. federal income tax liability. If we were to designate any portion of our net capital gain as retained net capital gain, non-U.S. holders should consult their tax advisors regarding the taxation of such retained net capital gain.

Sale of Our Stock Except as described below under “Redemption or Repurchase by Us,” gain realized by a non-U.S. holder upon the sale, exchange or other taxable disposition of our stock generally will not be subject to U.S. federal income tax unless such stock constitutes a USRPI. In general, stock of a domestic corporation that is a “United States real property holding corporation,” or USRPHC, will constitute a USRPI. We believe that we are a USRPHC. Our stock will not, however, constitute a USRPI so long as we are a “domestically controlled qualified investment entity.” A “domestically controlled qualified investment entity” includes a REIT in which at all times during a five-year testing period less than 50% in value of its stock is held directly or indirectly by non-United States persons, subject to certain rules. For purposes of determining whether a REIT is a “domestically controlled qualified investment entity,” a person who at all applicable times holds less than 5% of a class of stock that is “regularly traded” is treated as a United States person unless the REIT has actual knowledge that such person is not a United States person. Because our common stock is (and, we anticipate, will continue to be) publicly traded, no assurance can be given that we are or will continue to be a “domestically controlled qualified investment entity.”

Even if we do not qualify as a “domestically controlled qualified investment entity” at the time a non-U.S. holder sells our stock, gain realized from the sale or other taxable disposition by a non-U.S. holder of such stock would not be subject to U.S. federal income tax under FIRPTA as a sale of a USRPI if:

(1) such class of stock is “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market such as the New York Stock Exchange; and

(2) such non-U.S. holder owned, actually and constructively, 10% or less of such class of stock throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition or the non-U.S. holder’s holding period.

In addition, dispositions of our stock by “qualified foreign pension funds” or entities all of the interests of which are held by “qualified foreign pension funds” are exempt from FIRPTA. Non-U.S. holders should consult their tax advisors regarding the application of these rules.

Notwithstanding the foregoing, gain from the sale, exchange or other taxable disposition of our stock not otherwise subject to FIRPTA will be taxable to a non-U.S. holder if either (a) the investment in our stock is treated as effectively connected with the conduct by the non-U.S. holder of a trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment in the United States to which such gain is attributable), in which case the non-U.S. holder will be subject to the same treatment as U.S. holders with respect to such gain, except that a non-U.S. holder that is a corporation may also be subject to the 30% branch profits tax (or such lower rate as may be specified by an applicable income tax treaty) on such gain, as adjusted for certain items, or (b) the non-U.S. holder is a nonresident alien individual who is present in the United States for 183 days or more during the taxable year and certain other conditions are met, in which case the non-U.S. holder will be subject to a 30% tax on the non-U.S. holder’s capital gains (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the non-U.S. holder (even though the individual is not considered a resident of the United States), provided the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses. In addition, even if we are a domestically controlled qualified investment entity, upon disposition of our stock, a non-U.S. holder may be treated as having gain from the sale or other taxable disposition of a USRPI if the non-U.S. holder (1) disposes of such stock within a 30-day period preceding the ex-dividend date of a distribution, any portion of which, but for the disposition, would have been treated as gain from the sale or exchange of a USRPI and (2) acquires, or enters into a contract or option to acquire, or is deemed to acquire, other shares of that stock during the 61-day period beginning with the first day of the 30-day period described in clause (1), unless such class of stock is “regularly traded” and the non-U.S. holder did not own more than 10% of such class of stock at any time during the one-year period ending on the date of the distribution described in clause (1).

If gain on the sale, exchange or other taxable disposition of our stock were subject to taxation under FIRPTA or otherwise as a result of being effectively connected with the conduct by the non-U.S. holder of a trade or business within the United States, the non-U.S. holder would be required to file a U.S. federal income tax return and would be subject to regular U.S. federal income tax with respect to such gain in the same manner as a taxable U.S. holder (subject to any applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals). In addition, if the sale, exchange or other taxable disposition of our stock were subject to taxation under FIRPTA, and if shares of the applicable class of our stock were not “regularly traded” on an established securities market, the purchaser of such stock generally would be required to withhold and remit to the Internal Revenue Service 15% of the purchase price.

Redemption or Repurchase by Us A redemption or repurchase of shares of our stock will be treated under Section 302 of the Code as a distribution (and taxable as a dividend to the extent of our current and accumulated earnings and profits) unless the redemption or repurchase satisfies one of the tests set forth in Section 302(b) of the Code and is therefore treated as a sale or exchange of the redeemed or repurchased shares. See “Redemption or Repurchase by Us” under “Taxation of Taxable U.S. Holders of Our Stock” above. Qualified shareholders and their owners may be subject to different rules, and should consult

their tax advisors regarding the application of such rules. If the redemption or repurchase of shares is treated as a distribution, the amount of the distribution will be measured by the amount of cash and the fair market value of any property received. See “Distributions Generally” above. If the redemption or repurchase of shares is not treated as a distribution, it will be treated as a taxable sale or exchange in the manner described above under “- Sale of Our Stock.”

Taxation of Holders of Debt Securities of the Company or Welltower OP

The following summary describes the material U.S. federal income tax consequences of acquiring, owning and disposing of debt securities of the Company or Welltower OP. This discussion assumes the debt securities will be issued with less than a statutory de minimis amount of original issue discount for U.S. federal income tax purposes. In addition, this discussion is limited to persons purchasing the debt securities for cash at original issue and at their original “issue price” within the meaning of Section 1273 of the Code (i.e., the first price at which a substantial amount of the debt securities is sold to the public for cash).

U.S. Holders

Payments of Interest. Interest on a debt security generally will be taxable to a U.S. holder as ordinary income at the time such interest is received or accrued, in accordance with such U.S. holder’s method of accounting for U.S. federal income tax purposes.

Sale or Other Taxable Disposition A U.S. holder will recognize gain or loss on the sale, exchange, redemption, retirement or other taxable disposition of a debt security. The amount of such gain or loss generally will be equal to the difference between the amount received for the debt security in cash or other property valued at fair market value (less amounts attributable to any accrued but unpaid interest, which will be taxable as interest to the extent not previously included in income) and the U.S. holder’s adjusted tax basis in the debt security. A U.S. holder’s adjusted tax basis in a debt security generally will be equal to the amount the U.S. holder paid for the debt security. Any gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if the U.S. holder has held the debt security for more than one year at the time of such sale or other taxable disposition. Otherwise, such gain or loss will be short-term capital gain or loss. Long-term capital gains recognized by certain non-corporate U.S. holders, including individuals, generally will be taxable at reduced rates. The deductibility of capital losses is subject to limitations.

Non-U.S. Holders

Payments of Interest. Interest paid on a debt security to a non-U.S. holder that is not effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States generally will not be subject to U.S. federal income tax or withholding, provided that:

• the non-U.S. holder does not, actually or constructively, own 10% or more of the total combined voting power of all classes of our voting stock;

• the non-U.S. holder is not a controlled foreign corporation related to us through actual or constructive stock ownership; and

• either (1) the non-U.S. holder certifies in a statement provided to the applicable withholding agent under penalties of perjury that it is not a United States person and provides its name and address; (2) a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business and holds the debt security on behalf of the non-U.S. holder certifies to the applicable withholding agent under penalties of perjury that it, or the financial institution between it and the non-U.S. holder, has received from the non-U.S. holder a statement under penalties of perjury that such holder is not a United States person and provides the applicable withholding agent with a copy of such statement; or (3) the non-U.S. holder holds its debt security directly through a “qualified intermediary” (within the meaning of the applicable Treasury Regulations) and certain conditions are satisfied.

If a non-U.S. holder does not satisfy the requirements above, such non-U.S. holder will be subject to withholding tax of 30%, subject to a reduction in or an exemption from withholding on such interest as a result of an applicable tax treaty. To claim such entitlement, the non-U.S. holder must provide the applicable withholding agent with a properly executed Internal Revenue Service Form W-8BEN or W-8BEN-E (or other applicable documentation) claiming a reduction in or exemption from withholding tax under the benefit of an income tax treaty between the United States and the country in which the non-U.S. holder resides or is established.

If interest paid to a non-U.S. holder is effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment in the United States to which such interest is attributable), the non-U.S. holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the non-U.S. holder must furnish to the applicable withholding agent a valid Internal Revenue Service Form W-8ECI, certifying that interest paid on a debt security is not subject to withholding tax because it is effectively connected with the conduct by the non-U.S. holder of a trade or business within the United States.

Any such effectively connected interest generally will be subject to U.S. federal income tax at the regular rates. A non-U.S. holder that is a corporation may also be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected interest, as adjusted for certain items.

The certifications described above must be provided to the applicable withholding agent prior to the payment of interest and must be updated periodically. Non-U.S. holders that do not timely provide the applicable withholding agent with the required certification, but that qualify for a reduced rate under an applicable income tax treaty, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the Internal Revenue Service. Non-U.S. holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

Sale or Other Taxable Disposition A non-U.S. holder will not be subject to U.S. federal income tax on any gain realized upon the sale, exchange, redemption, retirement or other taxable disposition of a debt security (such amount excludes any amount allocable to accrued and unpaid interest, which generally will be treated as interest and may be subject to the rules discussed above in “Payments of Interest”) unless:

• the gain is effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment in the United States to which such gain is attributable); or

• the non-U.S. holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met.

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular rates. A non-U.S. holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

A non-U.S. holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on gain realized upon the sale or other taxable disposition of a debt security, which may be offset by U.S. source capital losses of the non-U.S. holder (even though the individual is not considered a resident of the United States), provided the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

Non-U.S. holders should consult their tax advisors regarding any applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

U.S. Holders A U.S. holder may be subject to information reporting and backup withholding when such holder receives payments on stock of the Company or debt securities of the Company or Welltower OP or proceeds from the sale or other taxable disposition of such stock or debt securities (including a redemption or retirement of a debt security). Certain U.S. holders are exempt from backup withholding, including corporations and certain tax-exempt organizations. A U.S. holder will be subject to backup withholding if such holder is not otherwise exempt and:

• the holder fails to furnish the holder’s taxpayer identification number, which for an individual is ordinarily his or her social security number;

• the holder furnishes an incorrect taxpayer identification number;

• the applicable withholding agent is notified by the Internal Revenue Service that the holder previously failed to properly report payments of interest or dividends; or

• the holder fails to certify under penalties of perjury that the holder has furnished a correct taxpayer identification number and that the Internal Revenue Service has not notified the holder that the holder is subject to backup withholding.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the Internal Revenue Service. U.S. holders should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption.

Non-U.S. Holders Payments of dividends on stock of the Company or interest on debt securities of the Company or Welltower OP generally will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person and the holder either certifies its non-U.S. status, such as by furnishing a valid Internal Revenue Service Form W-8BEN, W-8BEN-E or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the Internal Revenue Service in connection with any distributions on stock of the Company or interest on debt securities of the Company or Welltower OP paid to the non-U.S. holder, regardless of whether such distributions constitute a dividend or whether any tax was actually withheld. In addition,

proceeds of the sale or other taxable disposition of such stock or debt securities (including a retirement or redemption of a debt security) within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a United States person, or the holder otherwise establishes an exemption. Proceeds of a disposition of such stock or debt securities conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Copies of information returns that are filed with the Internal Revenue Service may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the non-U.S. holder resides or is established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a non-U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the Internal Revenue Service.

Medicare Contribution Tax on Unearned Income

Certain U.S. holders that are individuals, estates or trusts are required to pay an additional 3.8% tax on, among other things, dividends on stock, interest on debt obligations, and capital gains from the sale or other disposition of stock or debt obligations, subject to certain limitations. U.S. holders should consult their tax advisors regarding the effect, if any, of these rules on their ownership and disposition of our stock or debt securities.

Additional Withholding Tax on Payments Made to Non-U.S. Accounts

Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such sections commonly referred to as the Foreign Account Tax Compliance Act (“FATCA”)) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on stock of the Company, interest on debt securities of the Company or Welltower OP, in each case paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in clause (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on stock of the Company or interest on debt securities of the Company or Welltower OP. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of stock or debt securities on or after January 1, 2019, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued. Because we may not know the extent to which a distribution is a dividend for U.S. federal income tax purposes at the time it is made, for purposes of these withholding rules we may treat the entire distribution as a dividend.

Non-U.S. holders should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in stock of the Company or debt securities of the Company or Welltower OP.

Other Tax Consequences

State, local and non-U.S. income tax laws may differ substantially from the corresponding U.S. federal income tax laws, and this discussion does not purport to describe any aspect of the tax laws of any state, local or non-U.S. jurisdiction, or any U.S. federal tax other than income tax. You should consult your tax advisor regarding the effect of state, local and non-U.S. tax laws with respect to our tax treatment as a REIT and on an investment in our stock or debt securities.

In addition, the tax laws and regulations in non-U.S. jurisdictions may impose costs and expenses on the Company, its subsidiaries, and assets and investments of the Company held in non-U.S. jurisdictions (including the costs of compliance with and filings under applicable laws, rules and regulations). The Company has substantial assets, and will likely be subject to tax, reporting, legal, regulatory, and other obligations, in the U.K. and Canada. The treatment of an entity for U.S. federal income tax purposes may not be determinative of its treatment for certain state, local, or non-U.S. tax purposes.

Tax Aspects of Our Investments in Welltower OP and Subsidiary Partnerships

The following discussion summarizes certain U.S. federal income tax considerations applicable to our direct or indirect investments in subsidiary partnerships (including Welltower OP).

Classification as Partnerships We are required to include in our income our distributive share of Welltower OP’s and Subsidiary Partnerships’ income and are entitled to deduct our distributive share of Welltower OP’s and Subsidiary Partnerships’ losses only if the applicable partnership is classified for U.S. federal income tax purposes as a partnership rather than as a corporation or association taxable as a corporation. An organization will be classified as a partnership, rather than as a corporation, for U.S. federal income tax purposes if it (1) is treated as a partnership under Treasury regulations relating to entity classification (the “check-the-box regulations”) and (2) is not a “publicly traded partnership” taxable as a corporation.

Under the check-the-box regulations, an unincorporated entity with at least two members may elect to be classified either as an association taxable as a corporation or as a partnership. Generally, if such an entity fails to make an election, it generally will be treated as a partnership for U.S. federal income tax purposes. We believe that Welltower OP is classified as a partnership for U.S. federal income tax purposes.

A publicly traded partnership is a partnership whose interests are traded on an established securities market or are readily tradable on a secondary market (or the substantial equivalent thereof). While interests in Welltower OP and Subsidiary Partnership will not be traded on an established securities market, they could possibly be deemed to be traded on a secondary market or its equivalent due to the redemption rights enabling the limited members to dispose of their interests. A publicly traded partnership will not, however, be treated as a corporation for any taxable year if 90% or more of the partnership’s gross income for such year consists of certain passive-type income, including (as may be relevant here) real property rents, gains from the sale or other disposition of real property, interest, and dividends (the “90% Passive Income Exception”). The income requirements applicable to us in order for us to qualify as a REIT under the Code and the definition of qualifying income under the Passive Income Exception are very similar. Although differences exist between these two income tests, we do not believe that these differences would cause Welltower OP or Subsidiary Partnerships not to satisfy the 90% Passive Income Exception applicable to publicly traded partnerships.

If for any reason Welltower OP or a Subsidiary Partnership were taxable as a corporation, rather than as a partnership, for U.S. federal income tax purposes, our ability to qualify as a REIT could be jeopardized. See “Income Tests” and “Asset Tests.” In addition, any change in Welltower OP’s or a Subsidiary Partnership’s status for tax purposes might be treated as a taxable event, in which case we might incur tax liability without any related cash distribution. See “Annual Distribution Requirements.” Further, items of income and deduction of Welltower OP or a Subsidiary Partnership would not pass through to its members, and its members would be treated as shareholders for tax purposes. Consequently, Welltower OP or a Subsidiary Partnership would be required to pay income tax at corporate tax rates on its net income, and distributions to its members would constitute dividends that would not be deductible in computing such Welltower OP’s or Subsidiary Partnership’s taxable income.

Members, Not Partnership, Subject to Tax Except as discussed below in “Revised Partnership Audit Rules,” a partnership itself is not a taxable entity for U.S. federal income tax purposes. Rather, we are required to take into account our allocable share of each partnership’s income, gains, losses, deductions and credits for any taxable year of the partnership ending during our taxable year, without regard to whether we have received or will receive any distribution from such partnership.

Partnership Allocations Although a partnership agreement generally will determine the allocation of income and losses among partners, such allocations will be disregarded for tax purposes if they do not comply with the provisions of Section 704(b) of the Code and the Treasury regulations promulgated thereunder. If an allocation is not recognized for U.S. federal income tax purposes, the item subject to the allocation will be reallocated in accordance with the partners’ interests in the partnership, which will be determined by considering all of the facts and circumstances relating to the economic arrangement of the partners with respect to such item. Welltower OP’s and each Subsidiary Partnerships’ allocations of taxable income, gain and loss are intended to comply with the requirements of Section 704(b) of the Code and the Treasury regulations promulgated thereunder.

Tax Allocations with Respect to Certain Properties Pursuant to Section 704(c) of the Code, income, gain, loss and deduction attributable to appreciated or depreciated property that is contributed to a partnership in exchange for an interest in the partnership must be allocated in a manner such that the contributing partner is charged with, or benefits from, respectively, the unrealized gain or unrealized loss associated with the property at the time of the contribution. The amount of such unrealized gain or unrealized loss is generally equal to the difference between the fair market value of contributed property at the time of contribution and the adjusted tax basis of such property at the time of contribution (a “Book-Tax Difference”). Such allocations are solely for U.S. federal income tax purposes and do not affect the book capital accounts or other economic or legal arrangements among the partners. Welltower OP’s partnership agreement requires such allocations to be made in a manner permitted under Section 704(c) of the Code.

In general, the members who contribute property to Welltower OP will be allocated depreciation deductions for tax purposes which are lower than such deductions would be if determined on a pro rata basis. In addition, in the event of the disposition of any of the contributed assets (including our properties) which have a Book-Tax Difference, all gain or loss attributable to such Book-Tax Difference (to the extent not previously taken into account) will generally be allocated to the contributing members, including us, and other members will generally be allocated only their share of income attributable to gain or loss, if any, occurring after such contribution. This will tend to eliminate the Book-Tax Difference over the life of Welltower OP. However, the special allocation rules of Section 704(c) do not always entirely eliminate the Book-Tax Difference on an annual basis or with respect to a specific taxable transaction such as a sale. Thus, the carryover basis of the contributed assets in the hands of Welltower OP may cause us to be allocated lower depreciation and other deductions, and possibly an amount of taxable gain in the event of a sale of such contributed assets in excess of the economic or book income allocated to us as a result of such sale.

A Book-Tax Difference may also arise as a result of the revaluation of property owned by a partnership in connection with certain types of transactions, including in connection with certain non-prorata contributions of assets to, or distributions of assets by, Welltower OP in exchange for, or in redemption of, interests in Welltower OP. In the event of such a revaluation, the members (including us) who were members in the partnership immediately prior to the revaluation will be required to take any Book-Tax Difference created as a result of such revaluation into account in substantially the same manner as under the Section 704(c) rules discussed above. This would result in us being allocated income, gain, loss and deduction for tax purposes in amounts different than the economic or book income allocated to us by the partnership.

The application of Section 704(c) to Welltower OP may cause us to recognize taxable income in excess of cash proceeds, which might adversely affect our ability to comply with the REIT distribution requirements. See “Annual Distribution Requirements.” The foregoing principles also apply in determining our earnings and profits for purposes of determining the portion of distributions taxable as dividend income. The application of these rules over time may result in a higher portion of distributions being taxed as dividends than would have occurred had we purchased the contributed or revalued assets at their agreed values.

Treasury has issued regulations requiring partnerships to use a “reasonable method” for allocating items affected by Section 704(c) of the Code and outlining several reasonable allocation methods. We have the discretion to determine which of the methods of accounting for Book-Tax Differences (specifically approved in the Treasury regulations) will be elected with respect to any properties contributed to or revalued by Welltower OP. We have not determined which method of accounting for Book-Tax Differences will be elected for properties contributed to or revalued by Welltower OP in the future.

Basis in Partnership Interest Our adjusted tax basis in a partnership interest generally is equal to:

• the amount of cash and the adjusted tax basis of any other property contributed (or deemed contributed) by us to the partnership;

• increased by our allocable share of the partnership’s income, and

• reduced, but not below zero, by

◦our allocable share of the partnership’s loss, and

◦the amount of cash and the basis of any property distributed (or deemed distributed) to us.

If the allocation of our distributive share of the partnership’s loss would reduce the adjusted tax basis of our partnership interest in the partnership below zero, the recognition of such loss will be deferred until such time as the recognition of such loss would not reduce our adjusted tax basis below zero. To the extent that the partnership’s distributions (including deemed distributions) would reduce our adjusted tax basis below zero, such distributions would constitute taxable gain to us, which could be treated as ordinary income or long-term or short-term capital gain.

Partnership Audit Rules A partnership (and not its partners) must pay any “imputed underpayments,” consisting of delinquent taxes, interest, and penalties deemed to arise out of an audit of the partnership, unless certain alternative methods are available and the partnership elects to utilize them. The Internal Revenue Service has issued regulations providing details on many of these provisions, but it is still not entirely clear how all of these rules will be implemented. Accordingly, it is possible that in the future, we and/or any partnership in which we are a partner could be subject to, or otherwise bear the economic burden of, U.S. federal income tax, interest, and penalties resulting from a U.S. federal income tax audit.
