Item 1A. Risk Factors

In addition to the following risk factor and the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risk factors discussed in Part I, Item 1A of our Annual Report on Form 10-K (2021 10-K) for the year ended December 31, 2021 and any subsequent filings with the Securities and Exchange Commission (SEC), which could materially affect our business, financial condition, results of operations, cash flows or future results. The risks and uncertainties discussed below, in our 2021 10-K and in any subsequent filings with the SEC are not the only ones facing our business. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may materially adversely affect our business, cash flows, financial condition and/or results of operations. The risk factor below updates, and should be read together with, the risk factors disclosed in Part I, Item 1A of our 2021 10-K. Please also read the cautionary notice regarding forward-looking statements in Part I, Item 2 of this Quarterly Report on Form 10-Q under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations."

If the number or percentage of patients with higher-paying commercial insurance declines, if the average rates that commercial payors pay us decline, if commercial plans subject patients to restriction in plan designs, or if we are unable to maintain contracts with payors with competitive terms, including, without limitation, reimbursement rates, scope and duration of coverage and in-network benefits, it could have a material adverse effect on our business, results of operations, financial condition and cash flows.

A substantial portion of our U.S. dialysis net patient services revenues for the three and six months ended June 30, 2022 was generated from patients who have commercial payors as their primary payor. The majority of these patients have insurance policies that pay us on terms and at rates that are generally significantly higher than Medicare rates. As such our revenue and net income levels are sensitive to the number of our patients with higher-paying commercial insurance coverage and the percentage of our patients under higher paying commercial plans relative to government-based programs. The payments we receive from commercial payors generate nearly all of our profit and all of our nonacute dialysis profits come from commercial payors.

When traditional or original Medicare ("Medicare") becomes the primary payor for a patient, the payment rate we receive for that patient decreases from the commercial plan rate to the lower Medicare payment rate. If the number of our patients who have Medicare or another government-based program as their primary payor increases, it could negatively impact the percentage of our patients covered under commercial insurance plans. There are a number of factors that could drive a decline in the number or percentage of our patients covered under commercial insurance plans, including, among others, a continued decline in the rate of growth of the ESRD patient population, improved mortality, changes in the patient's or a family member's employment status, reduced availability of commercial health plans or reduced coverage by such plans through the ACA exchanges or otherwise due to changes to the laws, marketplace, healthcare regulatory system or otherwise. Commercial payors could also cease paying in the primary position after providing 30 months of coverage resulting in potentially material reductions in payment as the patient moves to Medicare primary. Declining macroeconomic conditions could also negatively impact the percentage of our patients covered under commercial insurance plans. To the extent there are job losses in the U.S., we could experience a decrease in the number of patients covered under commercial plans and/or an increase in uninsured and underinsured patients independent of whether general economic conditions improve. If we experience higher numbers of uninsured or underinsured patients, it also would result in an increase in uncollectible accounts.

Our arrangements and negotiations with payors also impact the number or percentage of patients with higher-paying commercial insurance. We continuously are in the process of negotiating existing and potential new agreements with commercial payors who aggressively negotiate terms with us, and we can make no assurances about the ultimate results of these negotiations or the timing of any potential rate changes resulting from these negotiations. Sometimes many significant agreements are being renegotiated at the same time. We believe payor consolidations have significantly increased the negotiating leverage of commercial payors, and ongoing consolidations may continue to increase this leverage in the future. In addition, our agreements and rates with commercial payors may be impacted by new business activities of these commercial payors as well as steps that these commercial payors have taken and may continue to take to control the cost of and/or the eligibility for access to the services that we provide, including, without limitation, relative to products on and off the healthcare

exchanges. These efforts could impact the number of our patients who are eligible to enroll in commercial insurance plans, and remain on the plans, including plans offered through healthcare exchanges. We continue to experience downward pressure on some of our rates with commercial payors as a result of these and other general conditions in the market, including, among other things, as employers seek to shift to less expensive options for medical services or as commercial payors dedicate increased focus on dialysis services.

Our negotiations with commercial payors may relate to commercial fee-for-service contracts, value-based care (VBC) contracts in which we share risk with commercial payors, as well as contracts to provide dialysis services to Medicare Part C MA patients. If we fail to maintain contracts with payors and other healthcare providers with competitive or favorable terms, either with respect to commercial plans, commercial VBC contracts, MA plans or otherwise, including, without limitation, with respect to reimbursement rates, scope and duration of coverage and in-network benefits, contract term or termination rights, or if we fail to accurately estimate the price for and manage our medical costs in an effective manner, whether due to inflationary pressures or otherwise, such that the profitability of our commercial or other value-based products is negatively impacted, it could have a material adverse effect on our business, results of operations, financial condition and cash flows. The ultimate result of our negotiations with payors cannot be predicted as they occur in a highly competitive environment and are influenced by marketplace dynamics such as those previously discussed. Among other things, these negotiations may result in termination or non-renewals of existing agreements, decreases in contracted rates, and reduction in the number of our patients that are covered by commercial plans, and we may not be able to enter into new agreements on competitive terms or at all. In the event that our ongoing negotiations with commercial payors result in overall rates reductions in excess of overall rate increases, the cumulative effect could have a material adverse effect on our business, results of operations, financial condition and cash flows. In addition, to the extent that these negotiations result in a reduction in the number of our patients covered by plans with commercial payors, it could have a material adverse effect on our business, results of operations, financial condition and cash flows. A material portion of both our commercial revenue and MA revenue is concentrated with a limited number of commercial payors, and any changes impacting our highest paying commercial payors or our relationships with these payors will have a disproportionate impact on us.

Certain payors have been attempting to design and implement plans that restrict access to ESRD coverage both in the commercial and individual market. Among other things, these restrictive plan designs seek to limit the duration and/or the breadth of ESRD benefits, limit the number of in-network providers, set arbitrary provider reimbursement rates, or otherwise restrict access to care, all of which may result in a decrease in the number of patients covered by commercial insurance or the reimbursement rate for ESRD services, among other things. Payors have also disputed the scope and duration of ESRD benefit coverage under their plans, and, among other things, have required patients to seek Medicare coverage for ESRD treatments. On June 21, 2022, the U.S. Supreme Court issued a decision in the matter of Marietta Memorial Hospital Employee Health Benefit Plan, et al. v. DaVita Inc. et al., a case evaluating the scope of the Medicare Secondary Payor Act (MSPA), deciding that a group health plan that provides limited benefits for outpatient dialysis, but does so uniformly for all plan participants, does not violate the terms of the MSPA because the plan treats all patients uniformly, regardless of whether a participant has ESRD and regardless of whether the participant is eligible for Medicare. For additional information, see Note 7 to the consolidated financial statements included in this report. We cannot reasonably estimate the ultimate impact of the U.S. Supreme Court’s decision at this time, as there is significant uncertainty as to, among other things, whether and to what extent payors may seek to design and implement plans to restrict access to ESRD in light of the decision; whether and how regulators and legislators will respond to the decision, including whether they will issue regulatory guidance or adopt new legislation; how courts will interpret other anti-discriminatory provisions that may apply; whether there could be other potential negative impacts of the decision and any resultant plan behavior on our commercial or government mix or the number of our patients covered by commercial insurance; and the timing of each of these items. Irrespective of any legislative or regulatory action in response to the decision, if more plans seek to implement plan designs that discourage or prevent ESRD patients from retaining their commercial coverage, it may lead to a decrease in the number of patients with commercial plans, the duration of benefits for patients under commercial plans and/or a decrease in the payment rates we receive, any of which could have a material adverse effect on our business, results of operations, financial condition and cash flows.

In addition, some commercial payors are pursuing or have incorporated policies into their provider manuals limiting or refusing to accept charitable premium assistance from non-profit organizations, such as the American Kidney Fund, which may impact the number of patients who are able to afford commercial plans. Paying for coverage is a significant financial burden for many patients, and ESRD disproportionately affects the low-income population. Charitable premium assistance supports continuity of coverage and access to care for patients, many of whom are unable to continue working full-time as a result of their severe health condition. Many patients with commercial and government insurance also rely on financial assistance from charitable organizations, such as the American Kidney Fund. Certain payors have challenged our patients' and other providers' patients' ability to utilize assistance from charitable organizations for the payment of premiums, including, without limitation, through litigation and other legal proceedings. The use of charitable premium assistance for ESRD patients has also faced challenges and inquiries from legislators, regulators and other governmental authorities, and this may continue. In addition,

CMS or another regulatory agency or legislative authority may issue a new rule or guidance that challenges or restricts charitable premium assistance. If any of these challenges to kidney patients' use of premium assistance is successful or restrictions are imposed on the use of financial assistance from such charitable organizations or if organizations providing such assistance are no longer available such that kidney patients are unable to obtain, or continue to receive or receive for a limited duration, such financial assistance, it may restrict the ability of dialysis patients to obtain and maintain optimal insurance coverage and could have a material adverse effect on our business, results of operations, financial condition and cash flows. In addition, if our assumptions about how kidney patients will respond to any change in financial assistance from charitable organizations are incorrect, it could have a material adverse effect on our business, results of operations, financial condition and cash flows.

Our negotiations and relationships with payors may also be impacted by legislative or regulatory developments and associated legal rulings. For example, the final rules for the 21st Century Cures Act, which are described in detail in Part I, Item 1. Business of the 2021 10-K under the heading "Government Regulation—21**st Century Cures Act," broadened ESRD patient access to certain enhanced benefits offered by MA plans. While these rules increased our MA plan enrollment for ESRD benefits in their first year, the potential ultimate impact of this change in benefit eligibility remains subject to change as market participants continue to adjust to this new regulatory environment. As an example, the removal of objective time and distance standards relating to network adequacy for outpatient dialysis centers for MA plans that was included in the final rules may adversely impact the number of ESRD patients that select MA plans and also may result in the Company not being an in-network provider for significant MA plans in the event MA plans attempt to use this revision to the rules to limit or restrict their networks. If kidney patients choose not to enroll in MA plans or choose to leave MA plans, whether due to network adequacy standards or otherwise, or if we fail to provide education to kidney patients in the manner specified by CMS, we could be subject to certain clinical, operational, financial and legal risks, which could have a material adverse effect on our business, results of operations, financial condition and cash flows. In addition, recent price transparency regulations require most group health plans and health insurance issuers in the group and individual markets to make certain pricing and patient responsibility information publicly available. For further detail on these regulations, see the discussion in Part I, Item 1. Business of the 2021 10-K under the heading "Government Regulation—Price Transparency Rules." On July 1, 2022, enforcement began of the requirement that plans publish machine readable files that include negotiated rates for all covered items and services with all providers and out-of-network allowed amounts. To comply with these requirements, plans have begun to publish these files and make them available to the public. The information that has been made available to date is highly diverse and complex. While the ultimate impact of these requirements remains uncertain, any changes by group health plans, health insurance issuers in the group and individual markets, or consumer choices resulting from these requirements could have a material adverse impact on our business, results of operations, and financial condition, and our reputation could be materially harmed. We could also experience a further decrease in the payments we receive for services if changes to the marketplace or the healthcare regulatory system result in fewer patients covered under commercial plans or an increase of patients covered under more restrictive commercial plans, or plans with lower reimbursement rates, among other things. For additional details regarding potential legislative or regulatory changes, the specific risks we face in connection with any decrease in payments we receive for services due to, for example, fewer patients being covered under commercial plans or an increase of patients covered under more restrictive commercial plans, or plans with lower reimbursement rates, please see Part I, Item 1. Business of the 2021 10-K under the heading "Government Regulation" and the discussion in the risk factor included in Part I, Item 1A. of the 2021 10-K under the heading "Changes in federal and state healthcare legislation or regulations could have a material adverse effect on our business, results of operations, financial condition and cash flows."

As noted, the foregoing dynamics of our arrangements and negotiations with commercial payors each may have an impact on, among other things, our ability to enter into and maintain contracts with payors with competitive terms, including, without limitation, reimbursement rates, scope and duration of coverage and in-network benefits as well as the number or percentage of our patients with higher-paying commercial insurance. If, as a result of these or other dynamics, we experience a decline in the average rates that commercial payors pay us or a reduction in the number of patients with ESRD coverage under higher-paying commercial plans either in total or relative to the number of patients under government-based programs that pay at lower rates or an increase in the number of patients that are uninsured or underinsured, it could have a material adverse effect on our business, results of operations, financial condition and cash flows.
