TABLE OF CONTENTS

PART I

Overview

Insulet Corporation (“we” or the “Company”) is primarily engaged in the development, manufacture and sale of its proprietary Omnipod® System, a continuous insulin delivery system for people with insulin-dependent diabetes, which we have been selling since 2005. The Omnipod System includes: the Omnipod Insulin Management System (“Classic Omnipod”), the Omnipod DASH® Insulin Management System (“Omnipod DASH”), and the Omnipod® 5 Automated Insulin Delivery System (“Omnipod 5”). In addition, substantially all of our Drug Delivery revenue consists of sales of pods to Amgen for use in the Neulasta® Onpro® kit, a delivery system for Amgen’s Neulasta to help reduce the risk of infection after intense chemotherapy.

Market Opportunity: Management of Diabetes

Diabetes is a chronic, life-threatening disease for which there is no known cure. It is caused by the body’s inability to produce or effectively utilize the hormone insulin, which prevents the body from adequately regulating blood glucose levels. Glucose, the primary source of energy for cells, must be maintained at certain concentrations in the blood in order to permit optimal cell function and health. In people with diabetes, blood glucose levels fluctuate between very high levels, a condition known as hyperglycemia, and very low levels, a condition called hypoglycemia. Hyperglycemia can lead to serious short-term complications, such as confusion, vomiting, dehydration, and loss of consciousness and long-term complications, such as blindness, kidney disease, nervous system disease, occlusive vascular diseases, stroke, cardiovascular disease, or death. Hypoglycemia can lead to confusion, loss of consciousness, or death.

Diabetes is typically classified as either type 1 or type 2:

• Type 1 diabetes is characterized by the body’s nearly complete inability to produce insulin. It is frequently diagnosed during childhood or adolescence. Individuals with type 1 diabetes require daily insulin therapy to survive. We estimate that approximately five million people have type 1 diabetes in the countries we currently serve.

• Type 2 diabetes, the more common form, is characterized by the body’s inability to either properly utilize insulin or produce enough insulin. Historically, type 2 diabetes has occurred in later adulthood, but its incidence is increasing among the younger population, due primarily to increasing obesity. Initially, many people with type 2 diabetes attempt to manage their diabetes with improvements in diet, exercise, and/or oral medications. As their diabetes advances, some individuals progress to multiple drug therapies, which often include insulin therapy. We estimate that approximately six million people have insulin-intensive type 2 diabetes in the countries we currently serve.

We estimate that approximately 40% of the type 1 diabetes population in the United States and even less of the international type 1 diabetes population use insulin pump therapy. An even smaller portion of the U.S. and international insulin-intensive type 2 diabetes population use insulin pump therapy. We believe these factors present a significant available market for the Omnipod System globally.

Throughout this Annual Report on Form 10-K, we refer to both type 1 diabetes and insulin-intensive type 2 diabetes as insulin-dependent diabetes.

Diabetes Management Challenges

Diabetes is often frustrating and difficult for people to manage. Blood glucose levels can be affected by the carbohydrate and fat content of meals, exercise, stress, illness, impending illness, hormonal releases, variability in insulin absorption, and changes in the effects of insulin on the body. For people with insulin-dependent diabetes, many corrections, consisting of the administration of additional insulin or ingestion of additional carbohydrates, are needed throughout the day in order to maintain blood glucose levels within normal ranges. Achieving this result can be very difficult with multiple daily injections of insulin. Individuals with diabetes attempting to control their blood glucose levels tightly to prevent the long-term complications associated with fluctuations in blood glucose levels are at greater risk for overcorrection and hypoglycemia. As a result, many people have difficulty managing their diabetes. Additionally, the time spent managing fluctuations in blood glucose levels and the fear associated with hypoglycemia can be incredibly stressful for individuals with diabetes and their families.

Current Insulin Therapy

People with insulin-dependent diabetes need a continuous supply of insulin, known as basal insulin, to provide for background metabolic needs. In addition to basal insulin, people with insulin-dependent diabetes require supplemental insulin, known as bolus insulin, to compensate for carbohydrates ingested during meals or snacks or for a high blood glucose level caused by other physiological reasons. There are two primary types of insulin therapy practiced today: multiple daily injections (“MDI”) therapy using syringes or insulin pens and pump therapy using insulin pumps.

MDI therapy involves the administration of fast-acting insulin before meals (bolus) to lower blood glucose levels to a healthy range. MDI therapy may also require a separate injection of a long-acting (basal) insulin, to control glucose levels between meals; typically, once or twice per day. By comparison, insulin pump therapy uses only fast-acting insulin to fulfill both mealtime (bolus) and background (basal) requirements. Insulin pump therapy allows individuals to customize their bolus and basal insulin doses to meet their insulin needs throughout the day and is intended to more closely resemble the physiologic function of a healthy pancreas.

Insulin pumps perform continuous subcutaneous insulin infusion and typically use a programmable device and an infusion set to administer insulin into the body. Insulin pump therapy has been shown to provide numerous advantages relative to MDI therapy. For example, insulin pump therapy eliminates individual insulin injections, delivers insulin more accurately and precisely than injections, often improves HbA1c (a common measure of blood glucose levels) over time, provides greater flexibility with meals, exercise, and daily schedules, and can reduce severe low blood glucose levels. We believe that these advantages, along with technological advancements, including the use of continuous glucose monitoring technology and automated insulin device (“AID”) algorithms, and increased awareness of insulin pump therapy will continue to generate demand for insulin pump devices.

Our Solution: The Omnipod System

The Omnipod System is a continuous insulin delivery system that provides all the benefits of insulin pump therapy in a unique way. We believe the Omnipod System’s innovative proprietary design and differentiated features allow people with insulin-dependent diabetes to live their lives and manage their diabetes, with unprecedented freedom, comfort, convenience, and ease.

Omnipod DASH			Omnipod 5

The Omnipod System features two discreet and easy-to-use devices that eliminates the need for the external tubing required with conventional pumps:

• a small, lightweight, self-adhesive disposable tubeless Omnipod device (“Pod”) that the user fills with insulin and wears directly on the body. It can be worn in multiple locations, including the abdomen, hip, back of upper arm, upper thigh, or lower back. The

Risks Related to Our Business and Industry

We currently rely on sales of the Omnipod System, and tailored versions of the Omnipod System in our Drug Delivery product line, to generate nearly all our revenue.

Our main product is the Omnipod System, from which we expect to continue to derive nearly all our revenue. Accordingly, our ability to continue to generate revenue is highly reliant on our ability to market and sell the Omnipod System and to retain consumers who currently use the product. Our sales of the Omnipod System may be negatively impacted by many factors, including:

• failure of the Omnipod System to achieve and maintain wide acceptance among opinion leaders in the diabetes treatment community, insulin-prescribing physicians, third-party payors, and people with insulin-dependent diabetes;

• manufacturing problems or capacity constraints;

• actual or perceived quality problems;

• reductions in reimbursement rates or coverage policies relating to the Omnipod System by third-party payors;

• claims that any portion of the Omnipod System infringes on intellectual property rights of others;

• adverse regulatory or legal actions relating to the Omnipod System;

• damage, destruction or loss of any of the facilities where our products are manufactured or stored or of the equipment therein;

• failure to successfully open or expand new facilities;

• the inability of users to continue paying for our products;

• attrition rates of consumers who cease using the Omnipod System;

• competitive pricing;

• results of clinical studies relating to the Omnipod System or our competitors’ products; and

• development of an effective patch pump by one or more competitors.

If any of these events occurs, our ability to generate revenue could be significantly reduced, which would adversely affect our business, financial condition, and results of operations.

If we fail to expand and maintain an effective sales force or successfully develop our relationships with intermediaries, our business, prospects and brand may be materially and adversely affected.

In addition to promoting, marketing, and selling the Omnipod System through our own direct sales force, we also utilize domestic and international intermediaries to distribute our product to users. We need to expand our distribution network to maintain and grow our business and revenue. We cannot assure you that we will be able to successfully develop our relationships with third-party intermediaries. If we fail to do so, our sales could fail to grow or could decline, and our ability to grow our business could be adversely affected. Intermediaries that are in the business of selling other medical products may not devote a sufficient level of resources and the support required to generate awareness of our products and grow or maintain product sales. If our intermediaries are unwilling or unable to market and sell our products, or if they do not perform to our expectations, we could experience delayed or reduced market acceptance and sales of our products, which would adversely affect our business, financial condition, and results of operations.

Our ability to grow our revenue depends in part on our retaining a high percentage of our customers.

A key to driving our revenue growth is the retention of a high percentage of our customers. We have developed retention programs aimed at both healthcare professionals and consumers, which include appeals assistance, ongoing customer communications, newsletters, support, training, and an automatic re-order program for certain customers. We have had a satisfactory customer retention rate; however, we cannot assure you that we will maintain this retention rate in the future. Current uncertainty in global economic conditions, competition, higher levels of unemployment, changes in insurance reimbursement levels, and negative financial news may negatively affect product demand. If demand for our products fluctuates as a result of economic conditions or otherwise, our ability to attract and retain customers could be harmed. The failure to retain a high percentage of our customers could negatively impact our revenue growth and may have a material adverse effect on our business, financial condition, and results of operations.

If we do not effectively manage our rapid growth, our business resources may become strained and we may not be able to deliver the Omnipod System in a timely manner, which could harm our results of operations.

As we continue to expand the number of customers we serve, driven in large part by significant demand for Omnipod 5, we expect to continue to increase our manufacturing capacity, our personnel, and the scope of our sales and marketing efforts. This growth, as well as any other growth that we may experience in the future, will provide challenges to our organization and may strain our management and operations resources, including our customer service. In order to manage future growth, we will be required to improve existing, and implement new, sales and marketing efforts, distribution channels, and customer support procedures. The form and function of our enterprise information technology systems will need to change and be improved upon as our business needs change. For example, we are currently working to implement a new enterprise resource planning system and significantly upgrade our customer relationship management system. We will also need to manage our supply chain and manufacturing effectively, including our sourcing of materials such as semiconductor chips. We may also need to partner with additional third-party suppliers to manufacture certain components of the Omnipod System and install additional manufacturing lines. A transition to new suppliers may result in additional costs or delays. We may misjudge the amount of time or resources that will be required to effectively manage any anticipated or unanticipated growth in our business, or we may not be able to manufacture sufficient inventory, or attract, hire and retain sufficient personnel to meet our needs. If we cannot scale our business appropriately, maintain control over expenses or otherwise adapt to anticipated and unanticipated growth, our business resources may become strained, we may not be able to deliver the Omnipod System in a timely manner, and our results of operations may be adversely affected.

Failure to secure or retain adequate coverage or reimbursement for our products by third-party payors could adversely affect our business, financial condition, and results of operations.

We expect that sales of the Omnipod System, which, in the U.S., occur only through the pharmacy channel for Omnipod 5 and primarily through the pharmacy channel for Omnipod DASH, will be limited unless a substantial portion of the sales price of the Omnipod System is paid for by third-party payors, including private insurance companies, health maintenance organizations, preferred provider organizations, federal and state government healthcare agencies, intermediaries, Medicare, Medicaid and other managed care providers. In the United States, we currently have contracts establishing reimbursement for

the Omnipod System with national and regional third-party payors and government agencies that provide reimbursement in all 50 states. Medicare Part D Plan Sponsors may provide coverage for the Omnipod System under the Medicare Part D prescription drug program, which requires negotiating with third-party payors in order to provide our product through the pharmacy channel in the United States. While we anticipate entering into additional contracts with other intermediaries and third-party payors, we cannot assure you that our efforts will be successful, which could limit the availability of the Omnipod System. In addition, these contracts can generally be terminated by the third-party payor without cause. Healthcare market initiatives in the United States may also lead

Overview

Our mission is to improve the lives of people with diabetes. We are primarily engaged in the development, manufacture, and sale of our proprietary Omnipod System, a continuous insulin delivery system for people with insulin-dependent diabetes. The Omnipod System features a small, lightweight, self-adhesive disposable tubeless Omnipod device that the user fills with insulin and wears directly on the body for up to three days at a time, which delivers personalized doses of insulin, and the PDM or Controller, a wireless handheld device that programs the Pod with the user’s personalized insulin-delivery instructions and wirelessly monitors the Pod’s operation.

The Omnipod System, includes: Classic Omnipod, its next generation Omnipod DASH, and the most recent generation Omnipod 5, all of which eliminate the need for multiple daily injections using syringes or insulin pens or the use of pump and tubing. Omnipod DASH features a secure Bluetooth enabled Pod and PDM with a color touch screen user interface supported by smartphone connectivity. Omnipod 5, which builds on our Omnipod DASH mobile platform, is a tubeless automated insulin delivery system, that integrates with a continuous glucose monitor (“CGM”) to manage blood sugar and is fully controlled by a compatible personal smartphone or Omnipod 5 Controller. The CGM is sold separately by a third party. In addition, substantially all of our Drug Delivery revenue consists of sales of pods to Amgen for use in the Neulasta® Onpro® kit, a delivery system for Amgen’s Neulasta to help reduce the risk of infection after intense chemotherapy.

Our long-term financial objective is to sustain profitable growth. To achieve this goal, our efforts have been focused on the launch of Omnipod 5, which in 2022 received FDA clearance for individuals aged two years and older with type 1 diabetes. Our limited market release of Omnipod 5 in the United States began in the first quarter, and in the third quarter we launched our U.S. full market release. We are also working to bring Omnipod 5 to our international markets. We recently received CE Mark approval under the European MDR, and we are currently focused on further building our international teams and advancing our regulatory, reimbursement, and market development efforts. We plan to launch Omnipod 5 in the U.K. and Germany in 2023 and to continue our international roll out more broadly in 2024.

In 2022, we completed our Omnipod 5 type 2 diabetes feasibility study and plan to begin a pivotal trial in 2023 with the goal of expanding Omnipod 5’s indication to type 2 users. Additionally, to accelerate our efforts to secure reimbursement for Omnipod 5, we have fully enrolled individuals in a randomized control trial in the U.S. and enrollment will begin soon in France. We also continue to expand market access and awareness of Omnipod through our direct to consumer advertising programs and through growing our presence in the U.S. pharmacy channel, where access to Omnipod 5 and Omnipod DASH is simpler and affordable, as no up-front investment is required. As we continue our growth in the pharmacy channel, we plan to phase-out our Classic Omnipod in the U.S. in 2023, since the vast majority of our customer base is no longer using this product.

Additionally, we continue to increase our presence within our existing markets and expand internationally in a targeted and strategic manner. We opened an office in Dubai to serve as our primary local presence and regional infrastructure in the Middle East, launched Omnipod in Saudi Arabia, and expanded into the United Arab Emirates.

We have also been taking steps to continue strengthening our global manufacturing capabilities. We are optimizing our operations in China by consolidating our production in that region into one location. Further, in 2022 we broke ground on a new manufacturing plant in Malaysia to support our international expansion strategy, further ensure product supply, and drive higher gross margins over time. We expect to begin production at this new manufacturing facility in 2024.

Finally, we continue to focus on our product development efforts, including AID offerings, such as choice of continuous glucose monitor and smartphone integration, and enhancing the customer experience through digital product and data capabilities. We have also developed a basal-only Pod for individuals with type 2 diabetes and submitted our 510(k) application to the FDA in November. We expect commercialization of the basal-only Pod in 2024.

Results of Operations

The discussion of our results of operations for 2020 has been omitted from this Form 10-K but can be found in Item 7. Management’s Discussion and Analysis and Results of Operations in our Form 10-K for the fiscal year ended December 31, 2021 filed with the Securities and Exchange Commission on February 24, 2022.

Factors Affecting Operating Results

Our Pods are intended to be used continuously for up to three days and then be replaced with a new disposable Pod. We recently achieved a milestone of 360,000 estimated global customers using Omnipod, including over 100,000 U.S. customers using the Omnipod 5. As we grow our customer base, we expect to generate an increasing portion of our revenues through recurring sales of our disposable Pods, which provides recurring revenue. Our recurring revenue business model, alongside the Omnipod System’s unique patented design enables us to provide pump therapy at a low or no up-front investment in regions where reimbursement allows for it. Our pay-as-you-go pricing model also reduces the risk to third-party payors.

During 2022, we issued two voluntary MDCs, one in October for our Omnipod DASH PDM related to its battery and the other in November for our Omnipod 5 Controller related to the charging port and cable. In addition to the estimated liability we recorded in 2022, we have a performance obligation to replace Omnipod DASH PDMs and Omnipod 5 Controllers sold subsequent to the MDC issuances, which is expected to negatively impact gross margins and net income in 2023, most notably in the first half of the year.

We have also experienced and expect to continue to experience challenges stemming from the global supply chain disruption that began during the coronavirus pandemic (“COVID-19”); however, to date we have been able to successfully mitigate this disruption and ensure uninterrupted supply to our customers by increasing our inventory levels and taking other measures. While our mitigation efforts and inflation have and are expected to continue to negatively impact gross margins and net income in 2023, we intend to continue to work to improve productivity to help offset these costs.

Comparison of the Years Ended December 31, 2022 and December 31, 2021

Revenue

(1) Constant currency revenue growth is a non-GAAP financial measure which should be considered supplemental to, and not a substitute for, our reported financial results prepared in accordance with GAAP. See “Management’s Use of Non-GAAP Measures.”

Total revenue for 2022 increased $206.5 million, or 18.8%, to $1,305.3 million, compared with $1,098.8 million in 2021. Constant currency revenue growth of 22.2% was primarily driven by higher volume and, to a lesser extent, favorable sales channel mix.

U.S. Omnipod

U.S. Omnipod revenue for 2022 increased $233.3 million, or 35.8%, to $884.8 million, compared with $651.5 million in 2021. This increase was primarily due to higher Omnipod 5 and Omnipod DASH volumes driven by growing our customer base and, to a lesser extent, growth through the pharmacy channel, where Pods have a higher average selling price due in part to the fact that we offer the PDM/Controller for no charge. Existing customer conversions to Omnipod 5 also contributed to the revenue increase as some users fill both their starter kit and their first month of refills simultaneously.

U.S. Omnipod revenue for 2022 includes $249.9 million of related party revenue, compared with $58.2 million in 2021. The $191.7 million increase primarily resulted from a shift in certain revenues from one distributor to another as we worked to extend our reach through the pharmacy channel. Additional information regarding our related party transactions is provided in Note 5 to our consolidated financial statements.

In 2023, we expect strong Omnipod revenue growth driven by continued volume growth of Omnipod 5 in the pharmacy channel, continued adoption of Omnipod DASH, and the benefits of our recurring revenue model.

International Omnipod

International Omnipod revenue for 2022 increased $3.1 million, or 0.9%, to $363.0 million, compared with $359.9 million in 2021. Excluding the 11.2% unfavorable impact of currency exchange, the remaining 12.1% increase was primarily due to higher volumes as we continue to expand awareness and access to Omnipod DASH, partially offset by increased competition from AID systems. In 2023, we expect higher International Omnipod revenue due to continued volume growth driven by the ongoing adoption of Omnipod DASH, partially offset by competition from AID systems and an unfavorable impact of currency exchange.

Drug Delivery

Drug Delivery revenue for 2022 decreased $29.9 million, or 34.2%, to $57.5 million, compared with $87.4 million in 2021. This decrease was primarily driven by a decline in production volume due to lower demand from our partner. In 2023, we expect Drug Delivery revenue to decline due to a lower demand forecast from our partner.

Operating Expenses

Cost of Revenue

Cost of revenue for 2022 increased $153.0 million, or 44.1%, to $499.7 million, compared with $346.7 million in 2021. Gross margin was 61.7% in 2022, compared with 68.4% in 2021. The 6.7 point decrease in gross margin was primarily driven by a $57.9 million net charge, or 4.5 points, associated with the voluntary MDCs we issued in 2022. The decrease was also driven by higher expected production costs in the U.S. as manufacturing continues to ramp and become a larger portion of our total production and higher costs associated with Omnipod 5 production. These decreases were partially offset by higher average selling price due to growth in the pharmacy channel, where Pods have a higher average selling price due in part to the fact that we offer the PDM/Controller for no charge.

We expect gross margin for 2023 to be in the range of 65% to 66%. We anticipate gross margin to increase due to significant costs associated with the MDCs in 2022, most of which we do not expect to recur in 2023 and higher volume in the pharmacy channel and favorable geographical sales mix. We believe these increases will be partially offset by continued higher production costs as we further scale U.S. manufacturing, unfavorable product line mix due to higher costs associated with Omnipod 5 production, and higher costs as we contend with inflation.

Research and Development

Research and development expenses for 2022 increased $20.1 million, or 12.6%, to $180.2 million, compared with $160.1 million in 2021. This increase was primarily due to year-over-year headcount additions to support our continued investment in development of Omnipod products, partially offset by lower outside services used for clinical activities. We expect research and development spending in 2023 to increase compared with 2022 as we continue to invest in advancing our innovation and clinical pipeline and contend with inflation.

Selling, General and Administrative

Selling, general and administrative expenses for 2022 increased $121.8 million, or 26.1%, to $587.8 million, compared with $466.0 million in 2021. This increase was primarily attributable to year-over-year headcount additions, mainly to support information technology and commercial operations and $25.2 million of legal charges related to the settlement of a patent infringement lawsuit, associated legal fees, and the settlement of a contract dispute. To a lesser extent, these increases were due to an increase in investments to expand market acceptance and access to Omnipod, higher travel and entertainment expenses due to increased activity as COVID-19 restrictions have lifted, an increase in software license fees driven by investments in new systems to support our growing business and headcount additions, and higher amortization of cloud computing implementation costs. Additionally, selling, general and administrative expenses include $3.4 million of costs associated with the retirement and advisory services of our former chief executive officer. These increases were partially offset by a decrease in direct-to-consumer advertising resulting from the timing of spend.

We expect selling, general and administrative expenses to increase in 2023 compared with 2022 due to investments in our operating structure to facilitate operational efficiencies and continued growth, including customer support and a new enterprise

resource planning system. Additionally, we plan to make investments to support the Omnipod System, including market acceptance and access, and the phased launch of Omnipod 5 in our international markets.

Non-Operating Items

Interest Expense, Net

Interest expense, net for 2022 decreased $34.5 million, or 56.4%, to $26.7 million, compared with $61.2 million in 2021. This decrease was primarily driven by the adoption of Accounting Standards Update 2020-06, Accounting for Convertible Debt Instruments and Contracts in an Entity's Own Equity (“ASU 2020-06”), which eliminated most of the non-cash interest expense associated with our convertible notes. Refer to Recently Adopted Accounting Standard in Note 2 to our consolidated financial statements for additional information.

Loss on Extinguishment of Debt

During 2021, we incurred a $42.4 million loss on extinguishment of debt related to the repurchase and conversion of all of our outstanding 1.375% Notes. Refer to Note 15 to our consolidated financial statements for additional information.

Other Expense, Net

Other expense, net for 2022 decreased $0.8 million to $1.1 million, compared with $1.9 million in 2021. The decrease was primarily driven by an increase in unrealized foreign currency gains, which was partially offset by realized foreign currency losses.

Income Tax Expense

Income tax expense was $5.2 million on pre-tax income of $9.8 million for 2022 and $3.7 million on pre-tax income of $20.5 million for 2021. Our effective tax rate was 53.4% and 18.2% for 2022 and 2021, respectively. The increase in our effective tax rate was primarily driven by a decrease in pre-tax income in the U.S. where we have net operating loss carryforwards to reduce taxable profits and a full valuation allowance against deferred tax assets. Refer to Note 22 to our consolidated financial statements for additional information on our income tax expense.

Adjusted EBITDA

The table below presents reconciliations of Adjusted EBITDA, a non-GAAP financial measure, to net income, the most directly comparable financial measure prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”):

(1) Represents net charge recorded for the estimated costs associated with the voluntary MDCs. Refer to Note 13 to our consolidated financial statements for additional information.

(2) Includes a $20.0 million charge to settle patent infringement litigation with Roche, associated legal fees, and a $3.6 million charge to settle a contract dispute. Refer to Note 17 to our consolidated financial statements for additional information.

(3) Represents costs associated with the retirement and advisory services of our former chief executive officer, including $2.3 million of accelerated stock-based compensation expense.

(4) Relates to the repurchase and conversion of all of our outstanding 1.375% Notes. Refer to Note 15 to our consolidated financial statements for additional information.

Non-GAAP Financial Measures

Management uses the following non-GAAP financial measures:

Constant currency revenue growth represents the change in revenue between current and prior year periods using the exchange rate in effect during the applicable prior year period. We present constant currency revenue growth because we believe it provides meaningful information regarding our results on a consistent and comparable basis. Management uses this non-GAAP financial measure, in addition to financial measures in accordance with GAAP, to evaluate our operating results. It is also one of the performance metrics that determines management incentive compensation.

Adjusted EBITDA represents net income (loss) plus net interest expense, income tax expense (benefit), depreciation and amortization, stock-based compensation expense and other significant transactions or events, such as legal settlements, medical device corrections, and loss on extinguishment of debt, that affect the period-to-period comparability of our operating performances, as applicable. We present Adjusted EBITDA because management uses it as a supplemental measure in assessing our operating performance, and we believe that it is helpful to investors, and other interested parties as a measure of our comparative operating performance from period to period. Adjusted EBITDA is a commonly used measure in determining business value and we use it internally to report results.

These non-GAAP financial measures should be considered supplemental to, and not a substitute for, our reported financial results prepared in accordance with GAAP. In addition, the above definitions may differ from similarly titled measures used by others. Non-GAAP financial measures exclude the effect of items that increase or decrease our reported results of operations; accordingly, we strongly encourage investors to review our consolidated financial statements in their entirety.

Liquidity and Capital Resources

Capitalization

The following table contains several key measures to gauge our financial condition and liquidity at the end of each year:

The increase in debt and the decrease in stockholders’ equity was primarily due to the adoption of ASU 2020-06. Refer to Recently Adopted Accounting Standard in Note 2 to our consolidated financial statements for additional information.

Convertible Debt

To finance our operations and global expansion, we have periodically issued convertible senior notes, which are convertible into our common stock. As of December 31, 2022, the following notes were outstanding:

(1) Per $1,000 face value of notes.

In connection with the issuance of the 0.375% Convertible Senior Notes (“0.375% Notes”), we purchased capped call options (“Capped Calls”) on our common stock. By entering into the Capped Calls, we expect to reduce the potential dilution to our common stock (or, in the event the conversion is settled in cash, to provide a source of cash to settle a portion of our cash payment obligation) in the event that at the time of conversion our stock price exceeds the conversion price under the 0.375% Notes. The Capped Calls have an initial strike price of $335.90 per share and cover 3.5 million shares of our common stock.

Credit Agreement

We have a $100 million three-year senior secured revolving credit facility (“Revolving Credit Facility”), which expires in 2024. At December 31, 2022, no amount was outstanding under the Revolving Credit Facility. The Revolving Credit Facility contains a covenant to maintain a specified leverage ratio under certain conditions when there are amounts outstanding under the facility.

It also contains other customary covenants, none of which are considered restrictive to our operations. Additionally, we have a seven year term loan, which matures in 2028, that contains covenants restricting or limiting our ability to incur additional indebtedness, make asset dispositions, create or permit liens, sell, transfer or exchange assets, guarantee certain indebtedness, and make acquisitions and other investments. Additional information regarding our debt is provided in Note 15 to the consolidated financial statements.

We believe that our current liquidity will be sufficient to meet our projected operating, investing, and debt service requirements for at least the next twelve months.

Summary of Cash Flows

Operating Activities

Net cash provided by operating activities of $119.0 million in 2022 was primarily attributable to net income, as adjusted for depreciation and amortization and stock-based compensation expense, partially offset by a $2.5 million working capital cash outflow. The working capital outflow was driven by a $36.8 million increase in prepaid expenses and other assets, a $51.8 million increase in accounts receivable, and a $49.1 million increase in inventories, partially offset by a $137.6 million increase in accrued expenses and other liabilities. The increase in prepaid expenses and other assets was primarily driven by an increase in cloud computing implementation costs. The increase in accounts receivable was primarily due to an increase in sales in the U.S. pharmacy channel, which has longer payment terms, partially offset by a decrease in unbilled accounts receivable related to lower production volumes of our Drug Delivery product. The increase in inventories was primarily driven by a planned inventory build to satisfy demand. Finally, the increase in accrued expenses and other liabilities was primarily driven by the voluntary MDCs issued for our Omnipod DASH PDMs and Omnipod 5 Controllers, an increase in rebates due to growth in the pharmacy channel and an increase in compensation costs due to higher incentive compensation achievement and head count additions.

Net cash used in operating activities of $68.1 million in 2021 was primarily attributable to net income, as adjusted for depreciation and amortization, loss on extinguishment of debt, non-cash interest, and stock-based compensation expense, partially offset by a $263.6 million working capital cash outflow. The working capital outflow was driven by a $154.4 million increase in inventories, a $71.3 million increase in accounts receivable and a $46.7 million increase in prepaid expenses and other assets, partially offset by a $24.4 million increase in accrued expenses and other liabilities. The increase in inventories was primarily driven by a planned inventory build to satisfy demand and the addition of our third highly automated manufacturing line. The increase in accounts receivable was primarily due to an increase in sales in the U,S. pharmacy channel, which has longer payment terms. The increase in prepaid expenses and other assets was primarily driven by an increase in cloud computing implementation costs. Finally, the increase in accrued expenses and other liabilities was primarily driven by an increase in rebates due to growth in the pharmacy channel and higher compensation costs due to an increase in both incentive compensation achievement and head count.

Investing Activities

We had $191.1 million of net cash used in investing activities in 2022, compared with $82.7 million in 2021.

Capital Spending—Capital expenditures were $122.9 million and $111.9 million in 2022 and 2021, respectively, and primarily related to the purchase of equipment to increase our manufacturing capacity. We expect capital expenditures for 2023 to decrease compared with 2022 given our significant investments to build capacity in 2022, including acceleration of some of our spending on machinery and equipment for our new Malaysia manufacturing facility that is under construction. We expect to fund our capital expenditures using existing cash.

*Investments in Developed Software—*Investments in developed software were $12.9 million and $10.8 million in 2022 and 2021, respectively, and primarily related to investments in projects to support our cloud-based capabilities.

Acquisitions and Investments—In 2022, we paid $26.0 million to acquire substantially all the assets related to the manufacture and production of shape-memory alloy wire assemblies that are used in the production of Omnipods from Dynalloy, Inc. and $21.5 million to acquire developed technology and patents from AGC. In addition we paid $7.8 million for strategic investments in two private companies.

Sales of Marketable Securities—The $40.0 million decrease in cash receipts from maturities of marketable securities in 2021 was driven by the prior year shift of a portion of our investment portfolio to investments that are classified as cash equivalents.

Financing Activities

We had $40.3 million of net cash used in financing activities in 2022, compared with $40.7 million of net cash provided by financing activities in 2021.

Debt Issuance and Repayment—During 2022, we made $24.5 million in aggregate principal payments on our equipment financings, mortgage, and term loan, compared with $22.3 million in 2021. The $2.2 million increase is due to entering the term loan and an additional equipment financing in the second and third quarters of 2021, respectively. During 2021, we received net proceeds of $489.5 million from the issuance of the term loan and used $460.9 million of cash to partially fund the repurchase of a portion of our 1.375% Notes. We also received net proceeds of $43.1 million from the equipment financing transaction entered into in 2021.

*Prepayments of Finance Lease Obligation—*During 2022, we made $15.3 million in upfront payments upon entering into an agreement to acquire real estate in Malaysia. Refer to Note 14 to the consolidated financial statements for additional information regarding this lease.

Option Exercises and Employee Stock Purchase Plan Proceeds—Total proceeds from option exercises and issuance of employee stock purchase plan shares were $16.3 million and $23.5 million in 2022 and 2021, respectively. The $7.2 million decrease was primarily driven by option exercises in the prior year by our former chief executive officer who retired in 2018.

Payment of Taxes for Restricted Stock Net Settlements—Payments for taxes related to net restricted and performance stock unit settlements were $16.8 million and $28.2 million in 2022 and 2021, respectively. The $11.4 million decrease was primarily driven by vesting of performance stock units in the prior year by our former chief executive officer who retired in 2018.

Commitments and Contingencies

Contractual Obligations—A summary of our contractual obligations and commitments for debt, operating lease obligations and other obligations at December 31, 2022 is presented in the following table:

(1)Interest on debt and lease obligations are projected for future periods using the interest rates in effect as of December 31, 2022. Certain of these projected interest payments may differ in the future based on changes in market interest rates. Additional information regarding our leases is provided in Note 14 to the consolidated financial statements.

(2)Excludes the impact of the interest rate swaps discussed in Note 16 to our consolidated financial statements.

(3)Purchase obligations include commitments for the purchase of Omnipod System components, commitments related to establishing additional manufacturing capabilities, and other commitments for purchases of goods or services in the normal course of business. These commitments are derived from purchase orders, supplier contracts and open orders based on projected demand information.

Off-Balance Sheet Arrangements

As of December 31, 2022, we had various letters of credit totaling $18.6 million. During 2022, the Company entered into a $20 million uncommitted letter of credit facility. In conjunction with the execution of an agreement to acquire real estate in Malaysia, including land and building, a letter of credit of $17.2 million was issued under this facility to backstop a bank guarantee for the same amount. The bank guarantee serves as security for the building while under construction. Additional information regarding our letters of credit is provided in Note 17 to the consolidated financial statements.

Critical Accounting Policies and Estimates

The preparation of our consolidated financial statements in conformity with U.S. GAAP requires management to use judgment in making estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. The following accounting policies are based on, among other things, judgments and assumptions made by management that include inherent risks and uncertainties. Management’s estimates are based on the relevant information available at the end of each period.

Revenue Recognition

We recognize revenue when a customer obtains control of the promised products in an amount that reflects the net consideration to which we expect to be entitled. We sell products both through distributors, who resell the products to consumers, and directly to consumers. Transaction price is typically based on contracted rates less any estimates of claim denials and historical reimbursement experience, guidelines and payor mix, and less estimated variable consideration adjustments, including rebates. Recognizing revenue requires us to exercise judgment and use estimates that can have a significant impact on the amount and timing of revenue we report. We exercise significant judgment when we determine variable consideration adjustments. The amount of variable consideration that is included in the transaction price is included in revenue only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. We estimate reductions to our revenues for rebates paid to distributors in the United States and Canada and pharmacy benefit managers (“PBM”) in the United States. Rebates are based on contractual arrangements, which may vary. Our estimates are based on products sold, historical experience, trends, specific known market events and, as available, channel inventory data. Rebates charged against gross sales amounted to $247.1 million, $143.3 million and $82.5 million in 2022, 2021 and 2020, respectively. Provisions for rebates, sales discounts, and returns are accounted for as a reduction of sales when revenue is recognized and are included within accounts receivable trade or accrued expenses and other current liabilities on our consolidated balance sheets, based upon the recipient of the rebate. If the actual amounts of consideration that we receive differ from our estimates, we adjust our estimates, which affects reported revenue in the period that such variances become known.

Our Drug Delivery product line includes sales of a modified version of the Omnipod to pharmaceutical and biotechnology companies who use our technology as a delivery method for their drugs. Revenue from the Drug Delivery product was $57.5 million for 2022. Revenue for this product line is recognized as the product is produced. Accounting for Drug Delivery revenue requires us to select a method to measure progress towards the satisfaction of the performance obligation. This election of the most meaningful measure of progress by which to recognize Drug Delivery revenue requires the application of judgment. We elected the input method and selected a blend of cost and time to produce as the measure of progress. Accordingly, revenue is recognized over time using a blend of costs incurred to date relative to total estimated costs at completion and time incurred to date relative to total production time to measure progress toward the satisfaction of our performance obligations. We believe that both incurred cost and elapsed time reflect the value generated, which best depicts the transfer of control to the customer. Contract costs include third-party costs as well as an allocation of manufacturing overhead. Changes from quarter to quarter in quantity and stage of production of in-process inventory could have a significant quarterly impact on revenue.

Product Warranty

We provide a four-year warranty on our PDMs and Controllers sold in the United States and Europe and a five-year warranty on PDMs sold in Canada. In addition, we may replace Pods that do not function in accordance with product specifications. We estimate our warranty obligation at the time the product is shipped based on historical experience and the estimated cost to service the claims, which include the current product cost, reclaim costs, shipping and handling costs and direct and incremental distribution and customer service support costs. Since we continue to introduce new products and versions, the anticipated performance of the product over the warranty period is also considered in estimating warranty reserves. Changes to the actual replacement rates, which are evaluated quarterly, could have a material impact on our estimated warranty reserve.

In 2022, we issued voluntary MDCs for the Omnipod DASH PDM and the Omnipod 5 Controller and accrued an associated warranty reserve of $68.9 million, which was subsequently reduced by $11.0 million primarily due to significantly fewer customers requesting a replacement Omnipod DASH PDM prior to our updated PDM being available. The remaining $54.6 million warranty reserve at December 31, 2022 includes an estimate regarding the number of:

• customers expected to request a replacement Omnipod 5 Controller;

• PDMs/Controllers that will be distributed by third parties and the cost of distribution assistance outside the U.S.;

• additional customer support personnel, their cost and the length of time they will be needed; and

• old PDMs expected to be returned for disposal and the cost of reclaim

Changes in these assumptions could have a material impact on our estimated warranty reserve related to the MDCs.

Intangible Assets

Certain of our intangible assets have been acquired through business combinations or asset purchases that include multiple components, both of which have required us to perform valuations. Our valuations involve assumptions, including, revenue and/or revenue growth rates associated with acquired assets, customer attrition rates, discount rate rates, royalty rates, tax rates, expected product development plans, product lifecycles, and obsolescence.

In 2022, we entered into an Asset Purchase Agreement pursuant to which we made a one-time payment of $25.0 million for the acquisition of technology and patents and the release of future obligations to AGC, including any future royalty obligations. This amount, together with transaction costs, was allocated between the assets acquired and the settlement component based on estimated relative fair value. The valuation of these intangible assets included assumptions based on future revenues, royalty rates, and obsolescence curves related to our Omnipod 5 product. In addition, since certain of the intangible assets were classified as defensive assets, the valuation included an assumption related to the probability that a claim made by Insulet would be successful. As a result of the relative fair value allocation, values of $12.0 million and $9.5 million were assigned to acquired technology and patents, respectively, and the settlement component was estimated to have a value of $3.6 million. Changes in these assumptions could impact the values assigned to the intangible assets acquired and, accordingly have a material impact on the amount attributed to the settlement component in our results of operations.

Inventory Reserves

We reduce the carrying value of inventories for items that are potentially excess, obsolete, or slow-moving based on changes in customer demand, technology developments, or other economic factors in order to state inventories at net realizable value. Factors influencing these adjustments include inventories on hand compared to estimated future usage and sales. During 2022, we charged $8.4 million to the consolidated statement of operations for excess and obsolete inventory, including $4.8 million related to the phase-out of Classic Omnipod. The determination of this charge involved assumptions regarding the number of PDMs expected to be utilized to satisfy warranty claims during the phase-out period and the length of time we will continue to offer Classic Omnipod outside the United States.

Forward-Looking Statements

This Annual Report on Form 10-K contains forward-looking statements. Forward-looking statements relate to future events or our future financial performance. We generally identify forward looking statements by terminology such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “intends,” “targets,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these terms or other similar words. These statements are only predictions. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, results of operations, and financial condition.

Forward-looking statements involve risks, uncertainties, and assumptions. Actual results may differ materially from those expressed in these forward-looking statements. You should not put undue reliance on any forward-looking statements.

The risk factors discussed in “Risk Factors” could cause our results to differ materially from those expressed in forward-looking statements. In addition, there may be other risks and uncertainties that we are unable to predict at this time or that we currently do not expect to have a material adverse effect on our business. We expressly disclaim any obligation to update these forward-looking statements other than as required by law.

Interest Rate Risk

Our exposure to changes in interest rates is associated with borrowings under our Revolving Credit Facility and our Term Loan, both of which are variable-rate debt. At December 31, 2022, no amounts were outstanding under our Revolving Credit Facility. In May 2021, we entered into two interest rate swap agreements to effectively convert $480.0 million of our term loan borrowings from a variable rate to a fixed rate. These interest rate swaps are intended to mitigate the exposure to fluctuations in interest rates and qualify for hedge accounting treatment as cash flow hedges. A 100 basis point increase or decrease in interest rates as of December 31, 2022 would decrease or increase our annual earnings, respectively, by approximately $0.1 million.

Market Price Sensitive Instruments

As of December 31, 2022, we had outstanding debt related to our convertible senior notes recorded on our consolidated balance sheet of $788.8 million, net of unamortized discount and issuance costs totaling $11.2 million. Changes in the fair value of our outstanding debt, which could be impacted by changes in interest rates, are not recorded in these consolidated financial statements as the debt is accounted for at cost less unamortized discount and issuance costs. The fair value of the convertible senior notes, which was $1,038.7 million as of December 31, 2022, is also impacted by changes in our stock price.

In order to reduce potential equity dilution, in connection with the issuance of the $800.0 million aggregate principal amount of 0.375% Notes, we entered into Capped Calls. We expect the Capped Calls to reduce the potential dilution to our common stock

(or, in the event the conversion is settled in cash, to provide a source of cash to settle a portion of our cash payment obligation) in the event that at the time of conversion our stock price exceeds the conversion price under the 0.375% Notes. The Capped Calls have an initial strike price of $335.90 per share and cover 3.5 million shares of common stock.

Foreign Currency Exchange Risk

Foreign currency risk arises from our investments in subsidiaries owned and operated in non-U.S. countries. Such risk is also a result of transactions with customers in countries outside the United States. Approximately 28% of our revenue was denominated in foreign currencies for the year ended December 31, 2022. As our business in regions outside of the United States continues to increase, we will be increasingly exposed to foreign currency exchange risk related to our foreign operations. The cost of revenue related to revenue generated outside of the United States is primarily denominated in U.S. dollars; however, operating costs related to these revenues are largely denominated in the same respective currencies, thereby partially limiting our transaction risk exposure. Fluctuations in the rate of exchange between the United States dollar and foreign currencies, primarily the Euro, British Pound and Canadian Dollar, could adversely affect our financial results, including our revenues, revenue growth rates, gross margins, income and losses as well as assets and liabilities.

We have intercompany receivables and payables from our foreign subsidiaries that are denominated in foreign currencies, principally the Euro, the British pound and the Canadian dollar. Fluctuations from the beginning to the end of a reporting period result in the revaluation of our foreign currency-denominated intercompany receivables and payables, generating currency translation gains or losses. Net realized and unrealized gains (losses) from foreign currency transactions are included in other (expense) income, net in the consolidated statement of operations and amounted to a loss of $1.3 million for the year ended December 31, 2022.

Our financial statements as of December 31, 2022 and 2021 and for each of the three years in the period ended December 31, 2022, and the Report of the Registered Independent Public Accounting Firm are included in this report as listed in the index.

Insulet Corporation

Opinions on the financial statements and internal control over financial reporting

We have audited the accompanying consolidated balance sheets of Insulet Corporation (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2022 and 2021, and the related consolidated statements of operations, comprehensive income, changes in stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2022, and the related notes and financial statement schedule included under Item 15(a) (collectively referred to as the “financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in the 2013 Internal Control*—*Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022 in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on criteria established in the 2013 Internal Control*—*Integrated Framework issued by COSO.

Change in accounting principle

As discussed in Note 2 to the financial statements, the Company changed its method of accounting for convertible debt in 2022 due to the adoption of Accounting Standards Update 2020-06, Debt – Debt With Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.

Basis for opinions

The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and limitations of internal control over financial reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical audit matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex

Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2022. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2022, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at a reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the three months ended December 31, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Management’s assessment included an evaluation of the design of the Company’s internal control over financial reporting and testing of the operational effectiveness of our internal control over financial reporting.
