NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

Note 1. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements reflect the consolidated operations of Insulet Corporation and its subsidiaries (“Insulet” or the “Company”). The unaudited consolidated financial statements have been prepared in United States dollars, in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of the consolidated financial statements in conformity with GAAP requires management to make use of estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results may differ from those estimates. In management’s opinion, the unaudited consolidated financial statements contain all normal recurring adjustments necessary for a fair statement of the interim results reported. Operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2020, or for any other subsequent interim period.

The year-end balance sheet data was derived from audited consolidated financial statements. These unaudited consolidated financial statements do not include all of the annual disclosures required by GAAP; accordingly, they should be read in conjunction with the Company’s audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Accounts Receivable and Allowance for Credit Losses

Trade accounts receivable consist of amounts due from third-party payors, customers and intermediaries and are presented at amortized cost. The allowance for credit losses reflects an estimate of losses inherent in the Company’s accounts receivable portfolio determined based on historical experience, specific allowances for known troubled accounts and other available evidence. Accounts receivable are written off when management determines they are uncollectable.

The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. The Company has identified the following portfolio segments and measures the allowance for credit losses using the following methods:

Direct Customer Receivables—The Company measures expected credit losses on direct customer receivables using an aging methodology. The risk of loss for direct customer receivables is higher than other portfolios. The Company relies on third-party payors to accept and timely process claims and on direct consumers to have the ability to pay. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and supportable forecasts.

Distributor Receivables—The Company measures expected credit losses on distributor receivables using an individual reserve methodology. The risk of loss in this portfolio is low based on the Company’s historical experience. The estimate of expected credit losses considers payment history as well as credit ratings of the distributors, in addition to current conditions and supportable forecasts.

National Healthcare System Receivables—The Company measures expected credit losses on national healthcare system receivables using an individual reserve methodology. The risk of loss in this portfolio is low based on the Company’s historical experience. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and supportable forecasts.

Shipping and Handling Costs

Shipping and handling costs are included in selling, general and administrative expenses and were $1.9 million and $2.3 million for the three months ended June 30, 2020 and 2019, respectively, and were $3.8 million and $4.9 million for the six months ended June 30, 2020 and 2019, respectively.

Fair Value Measurements

Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. To measure fair value of assets and liabilities, the Company uses the following fair value hierarchy based on three levels of inputs:

Level 1—observable inputs, such as quoted prices in active markets for identical assets or liabilities;

Level 2—significant other observable inputs that are observable either directly or indirectly; and

Level 3—significant unobservable inputs for which there are little or no market data, which require the Company to develop its own assumptions.

Table of Contents

Certain of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other liabilities are carried at cost, which approximates their fair value because of their short-term maturity. See Notes 3 and 8 for financial assets and liabilities held at carrying amount on the consolidated balance sheet and Note 4 for investments measured at fair value on a recurring basis.

Reclassification of Prior Period Amounts

Certain reclassifications have been made to prior period amounts to conform to the current period financial statement presentation. A portion of facility costs and certain information technology costs have been allocated from selling, general and administrative to research and development expenses based on square foot and system usage, respectively. In addition, certain quality assurance costs were reclassified from research and development expenses to selling, general and administrative expenses. The net impact of these adjustments was a $0.7 million and $1.3 million increase to research and development expenses and a corresponding decrease to selling, general and administrative expenses for the three and six months ended June 30, 2020, respectively. There was no change to previously reported operating or net income. Further, the Company reclassified the $1.6 million change in unbilled receivables from the change in accounts and unbilled receivables to the change in prepaid expenses and other assets in the prior year statement of cash flows. This reclassification had no effect on previously reported net cash provided by operating activities.

Recently Adopted Accounting Standards

Effective January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) 2016-13, Credit Losses (Topic 326) (“ASU 2016-13”). ASU 2016-13 requires financial assets measured at amortized cost, such as the Company’s trade receivables and contract assets, to be presented net of expected credit losses, which may be estimated based on relevant information such as historical experience, current conditions and future expectation for each pool of similar financial assets. The new guidance also requires enhanced disclosures related to trade receivables and associated credit losses. The Company adopted ASU 2016-13 using the modified retrospective method, whereby the guidance is applied prospectively as of the date of adoption and prior periods are not restated. The cumulative effect of adopting ASU 2016-13 resulted in a $1.1 million increase to the opening balance of accumulated deficit upon adoption related to an increase in the allowance for credit losses on accounts receivable.

The following table presents the activity in the allowance for credit losses for the three and six months ended June 30, 2020, comprised primarily of our direct consumer receivable portfolio. The allowance for credit losses of other portfolios is insignificant.


(in millions)	Three Months Ended June 30, 2020		Six Months Ended June 30, 2020
Credit losses at the beginning of the period	$	4.1	$	3.8
Effect of adoption	—		1.1
Credit losses at the beginning of the period after adoption	4.1		4.9
Provision for expected credit losses	2.0		2.6
Write-offs charged against allowance	(1.6)		(3.1)
Recoveries of amounts previously written-off	0.1		0.2
Credit losses at the end of the period	$	4.6	$	4.6

Effective January 1, 2020, the Company adopted ASU 2017-04, Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 requires an entity to measure the impairment of goodwill assigned to a reporting unit as the amount by which the carrying value of the assets and liabilities of the reporting unit, including goodwill, exceeds the reporting units’ fair value. The adoption of this guidance had no impact on the consolidated financial statements.

Note 2. Revenue and Contract Acquisition Costs

The following table summarizes the Company’s disaggregated revenues:

Product Warranty Costs

The Company provides a four-year warranty on Personal Diabetes Managers (“PDMs”) sold in the United States and Europe and a five-year warranty on PDMs sold in Canada and may replace Pods that do not function in accordance with product specifications. The Company estimates its warranty at the time the product is shipped based on historical experience and the estimated cost to service the claims. Since the Company continues to introduce new products and versions, the anticipated performance of the product over the warranty period is also considered in estimating warranty reserves. Warranty expense is recorded in cost of revenue in the consolidated statements of operations. Cost to service the claims reflects the current product cost.

The following table is a summary of the activity related to the Company’s product warranty liability:

Note 9. Commitments and Contingencies

Legal Proceedings

Between May 5, 2015 and June 16, 2015, three class action lawsuits were filed by shareholders in the U.S. District Court, for the District of Massachusetts, against the Company and certain then current and former executives of the Company. Two suits subsequently were voluntarily dismissed. Arkansas Teacher Retirement System v. Insulet, et al., 1:15-cv-12345, (“ATRS”) alleged that the Company (and certain then current and former executives) committed violations of Sections 10(b) and 20(a) and Rule 10b-5 of the Securities Exchange Act of 1934 by making allegedly false and misleading statements about the Company’s business, operations and prospects. On February 8, 2018, the parties executed a binding stipulation of settlement, under which all claims were released, and a payment was made into an escrow account for the plaintiffs and the class they purport to represent. On August 6, 2018, the Court issued an order approving the settlement, but took the plaintiffs’ motion for fees and expenses under advisement, which motion remains pending. The Company had previously accrued fees and expenses in connection with this matter for the amount of the final settlement liability that was not covered by insurance, the amount of which was not material to the Company’s consolidated financial statements.

In addition, on April 26, 2017, a derivative action (Walker v. DeSisto, et al., 1:17-cv-10738) (“Walker”) was filed, and on October 13, 2017, a second derivative action (Carnazza v. DeSisto, et al., 1:17-cv-11977) (“Carnazza”) was filed, both on behalf of the Company, each by a shareholder in the U.S. District Court for the District of Massachusetts against the Company (as a nominal defendant) and certain individual then current and former officers and directors of the Company. The allegations in the actions are substantially similar to those alleged in the securities class action. The actions seek, among other things, damages, disgorgement of certain types of compensation or profits, and attorneys’ fees and costs. On July 11, 2018, the parties executed a binding stipulation of settlement, under which all claims were released, and a payment of attorneys’ fees and reimbursement of expenses will be paid to plaintiffs’ counsel, subject to the Court’s approval. On July 13, 2018, the plaintiffs filed a motion for preliminary approval of the settlement, which is pending. The Company expects that such fees and expenses payable to plaintiff’s counsel will be covered by the Company’s insurance.

In June 2020, Roche Diabetes Care, Inc. (“Roche”) filed a patent infringement lawsuit against the Company in the United States District Court for the District of Delaware alleging that the Company’s manufacture and sale of its Omnipod Insulin Management System, Omnipod Starter Kit and Omnipod 10 Pod Pack in the United States infringed Roche’s now-expired U.S. Patent 7,931,613. Roche is seeking monetary damages and attorneys’ fees and costs. Since the patent expired in 2019, Roche is not seeking injunctive relief and the lawsuit will have no impact on ongoing sales of the Company’s products. The Company believes that it has meritorious defenses to Roche’s claims and intends to vigorously defend against them. At this time, based on available information regarding this litigation, the Company is unable to reasonably assess the ultimate outcome of this case or determine an estimate, or range of estimates, of potential losses. The court has not yet set a schedule for the case.

Table of Contents

In July 2020, the Company filed a patent infringement claim against Roche Diabetes Care Limited (“Roche Ltd.”) in the United Kingdom alleging that Roche Ltd.’s manufacture and sale of the Accu-Chek® Solo insulin pump and its consumable components infringes European Patent No. 1 335 764 in the United Kingdom. The Company is seeking an injunction to last until expiry of the patent and monetary damages.

The Company is, from time to time, involved in the normal course of business in various legal proceedings, including intellectual property, contract, employment and product liability suits. Other than as described above, the Company does not expect the outcome of these proceedings, either individually or in the aggregate, to have a material adverse effect on its results of operations.

Fees to Former European Distributor

Following the expiration of an agreement with a former European distributor on June 30, 2018, the Company was required to pay a quarterly per-unit fee for Omnipod sales to certain customers of the former European distributor for a one-year period through June 30, 2019. The Company recognized a liability and an associated intangible asset for this fee as qualifying sales occurred. The methodology applicable for determining the total fee under the distribution agreement is subject to an active arbitration proceeding in Switzerland. The final amount of the fee could vary significantly depending on the number of customers who count for purposes of calculating the fee under the terms of the agreement. The Company estimates that the final aggregate fee is in the range of $5 million to $55 million. As of both June 30, 2020 and December 31, 2019, the Company had $2.7 million accrued related to this matter. The associated gross intangible asset was $7.8 million at both June 30, 2020 and December 31, 2019.

Note 13. Income Taxes

The Company’s effective tax rate for the three and six months ended June 30, 2020 was 17.2% and 17.0%, compared with 25.6% and 12.3% for the three and six months ended June 30, 2019. Income tax benefits have not been recorded for losses in jurisdictions where valuation allowances exist against net deferred tax assets, primarily in the United States. As of June 30, 2020 and December 31, 2019, the Company maintained a full valuation allowance against its U.S. net deferred tax assets based on the determination that it is not more likely than not these future benefits will be realized. The Company had no uncertain tax positions at both June 30, 2020 and December 31, 2019.

In April 2020, new interpretations of a German tax law related to intellectual property and withholding tax were released. The Company is evaluating whether these new interpretations, applicable to corporate multinationals, will have an impact on the consolidated financial statements.

Note 14. Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted net income per share is computed using the weighted average number of common shares outstanding and, when dilutive, common share equivalents from outstanding stock options and restricted stock units (using the treasury-stock method), and potential common shares from the Company’s convertible notes (using the if-converted method). The weighted-average number of common shares used in the computation of basic and diluted net income per share were as follows:


	Three Months Ended June 30,			Six Months Ended June 30,
(in millions)	2020	2019	2020	2019
Weighted average number of common shares outstanding, basic	64,370,791	59,844,991	63,627,231	59,601,365
Stock options	1,086,474	1,479,713	1,129,985	1,513,886
Restricted stock units	121,248	161,621	212,971	217,200
Weighted average number of common shares outstanding, diluted	65,578,513	61,486,325	64,970,187	61,332,451

The number of common share equivalents excluded from the computation of diluted net income per share because either the effect would have been anti-dilutive, or the performance criteria related to the units had not yet been met, were as follows:


	Three Months Ended June 30,			Six Months Ended June 30,

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the accompanying notes included in this quarterly report. The following discussion may contain forward-looking statements that reflect our plans, estimates and beliefs and involve risks, uncertainties and assumptions. Our actual results could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to these differences include those discussed under the headings “Risk Factors” and “Forward-Looking Statements” in both our annual report on Form 10-K for the year ended December 31, 2019 and in this quarterly report.

Overview

We are primarily engaged in the development, manufacture and sale of our proprietary Omnipod^® System (“Omnipod”), an innovative, continuous insulin delivery system for people with insulin-dependent diabetes. There are two primary types of insulin therapy practiced today: multiple daily injection (“MDI”) therapy using syringes or insulin pens; and pump therapy using insulin pumps. Insulin pumps are used to perform continuous subcutaneous insulin infusion, or insulin pump therapy, and typically use a programmable device and an infusion set to administer insulin into a person’s body. Insulin pump therapy has been shown to provide people with insulin-dependent diabetes with numerous advantages relative to MDI therapy. The Omnipod System features a small, lightweight, self-adhesive disposable tubeless Omnipod device (“Pod”) that is worn on the body for up to three days at a time; and its wireless companion, the handheld Personal Diabetes Manager. The Omnipod System, which features discreet and easy-to-use devices communicates wirelessly, provides for virtually pain-free automated cannula insertion and eliminates the need for traditional MDI therapy or the use of traditional pump and tubing. We believe that the Omnipod System’s unique proprietary design and features allow people with insulin-dependent diabetes to manage their diabetes with unprecedented freedom, comfort, convenience and ease.

In addition to the diabetes market space, we have partnered with pharmaceutical and biotechnology companies to tailor the Omnipod System technology platform for the delivery of non-insulin subcutaneous drugs across other therapeutic areas. Most of our drug delivery revenue currently consists of sales of Pods to Amgen for use in the Neulasta^® Onpro^® kit, an innovative delivery system for Amgen’s white blood cell booster to help reduce the risk of infection after intense chemotherapy.

Our mission is to improve the lives of people with diabetes. To assist in achieving this mission, we are focused on the following key strategic imperatives:

•delivering consumer-focused innovation;

•ensuring the best customer experience globally;

•expanding our global footprint; and

•driving operational excellence.

Our long-term financial objective is to sustain profitable growth. To achieve this goal, we expect our efforts in 2020 to focus primarily on the pivotal trial in the United States for Omnipod 5, powered by Horizon™ (“Omnipod 5”), our automated insulin delivery system. In order to support our continued growth and the expected launch of Omnipod 5 in the first half 2021, we continue to focus on adding capacity to our U.S. manufacturing plant. During the first quarter of 2020, we began producing salable product on our second manufacturing line in the U.S. and we plan to install a third line in the second half of 2020, on which production is expected in 2021.

Additionally, in 2020, we had planned to further roll out our Omnipod DASH^TM Insulin Management System (“Omnipod DASH”), our next generation digital mobile Omnipod platform, in Europe and Canada and enter five new countries in Western Europe and the Middle East to expand the commercial sale of Omnipod and our global footprint. We are still committed to the further roll out of Omnipod DASH and to entering new countries, although the timing has shifted to early 2021 primarily due to the coronavirus pandemic discussed under Recent Developments below. This change in expected timing will not have a material impact on our 2020 revenues since we did not expect these actions to have a meaningful contribution in 2020, although they are expected to contribute to our long-term growth.

Finally, we plan to continue our product development efforts and expand awareness of and access to our products. Achieving the above strategic imperatives is expected to require additional investments in certain initiatives and personnel, as well as enhancements to our supply chain operation capacity, efficiency and effectiveness.

Recent Developments

A novel strain of coronavirus (“COVID-19”) was identified in China in December 2019, and subsequently declared a pandemic by the World Health Organization in March 2020. The COVID-19 outbreak in China resulted in abnormally low production at our contract manufacturer in China during the first two months of the year, which resulted in incremental depreciation expense for under-utilized plant capacity for those two months. In response to this outbreak, we took measures to ensure our ability to continue to provide product to our customers, including providing manufacturing incentives to our contract manufacturer in China and utilizing expedited, but more costly, shipping measures to transport product from China. In addition, we implemented strict screening and additional sanitation measures.

Table of Contents

China, where we manufacture a significant portion of our products, has begun to experience recovery from COVID-19 and we have been able to produce at normal capacity since March. Additionally, our second highly automated manufacturing line in our U.S. manufacturing plant has provided additional manufacturing redundancy to help mitigate manufacturing risks stemming from COVID-19. Once fully ramped, we expect the two highly-automated lines in our U.S. manufacturing plant to provide us with capacity in the U.S. that is equivalent to all our current lines in China. Refer to Item 1A. Risk Factors for a discussion of COVID-19 risks.

Revenue

Total revenue for the three months ended June 30, 2020 increased $49.2 million, or 27.8%, to $226.3 million, compared with $177.1 million for the three months ended June 30, 2019. Constant currency revenue growth of 28.8% was primarily driven by higher volume and, to a lesser extent, favorable sales channel mix.

Total revenue for the six months ended June 30, 2020 increased $87.6 million, or 26.0%, to $424.3 million, compared with $336.7 million for the six months ended June 30, 2019. Constant currency revenue growth of 27.1% was primarily driven by higher volume and, to a lesser extent, favorable sales channel mix.

U.S. Omnipod

U.S. Omnipod revenue for the three months ended June 30, 2020 increased $30.7 million, or 31.3%, to $128.8 million, compared with $98.1 million for the three months ended June 30, 2019. This increase was primarily due to higher volumes driven by growing our customer base, and to a lesser extent, an increase in days-on-hand inventory at distributors due to both continued growth of DASH adoption and COVID-19. The increase was also due to growth through the pharmacy channel, where Pods have a higher average selling price due in part to the fact that we offer the PDM for no charge.

U.S. Omnipod revenue for the six months ended June 30, 2020 increased $61.2 million, or 33.2%, to $245.4 million, compared with $184.2 million for the six months ended June 30, 2019. This increase was primarily due to higher volumes driven by growing our customer base, and to a lesser extent, an increase in days-on-hand inventory at distributors due to both continued growth of DASH adoption and COVID-19. The increase was also due to growth through the pharmacy channel, where Pods have a higher average selling price due in part to the fact that we offer the PDM for no charge. For full year 2020, we expect strong Omnipod revenue growth driven by continued market penetration and volume growth of Omnipod DASH, primarily in the pharmacy channel. We expect this revenue growth to be partially offset by the impact of lower new Omnipod starts stemming from COVID-19.

International Omnipod

International Omnipod revenue for the three months ended June 30, 2020 increased $10.5 million, or 16.7%, to $73.2 million, compared with $62.7 million for the three months ended June 30, 2019. Excluding the 3.0% unfavorable impact of currency exchange,

Table of Contents

the remaining 19.7% increase in revenue was primarily driven by higher volumes as we continue to expand awareness and access to the Omnipod and, to a lesser extent, an increase in days-on-hand inventory at distributors due to COVID-19.

International Omnipod revenue for the six months ended June 30, 2020 increased $26.7 million, or 22.3%, to $146.3 million, compared with $119.6 million for the six months ended June 30, 2019. Excluding the 3.2% unfavorable impact of currency exchange, the remaining 25.5% increase in revenue was primarily driven by higher volumes as we continue to expand awareness and access to the Omnipod and, to a lesser extent, an increase in days-on-hand inventory at distributors due to COVID-19. Similar to in the U.S, for the full year 2020, we expect higher International Omnipod revenue due to continued volume growth and market penetration. We expect this revenue growth to be partially offset by the impact of lower new Omnipod starts stemming from COVID-19.

Drug Delivery

Drug Delivery revenue for the three months ended June 30, 2020 increased $8.0 million, or 49.1%, to $24.3 million, compared with $16.3 million for the three months ended June 30, 2019, due to increased demand driven by COVID-19 and shift in the timing of production between the first and second quarter.

Drug Delivery revenue for the six months ended June 30, 2020 was relatively level compared with the six months ended June 30, 2019. For full year 2020, we expect Drug Delivery revenue to increase due to a higher demand forecast resulting from COVID-19.

Cost of Revenue

Cost of revenue for the three months ended June 30, 2020 increased $23.1 million, or 38.1%, to $83.8 million, compared with $60.7 million for the three months ended June 30, 2019. Gross margin was 63.0% for the three months ended June 30, 2020, compared with 65.7% for the three months ended June 30, 2019. The 270 basis point decrease in gross margin was primarily due to start-up costs and inefficiencies related to our new U.S. manufacturing operations, and $3.4 million for recruiting and screening expenses, expedited shipping costs and manufacturing incentives associated with our contract manufacturer in China as a result of the coronavirus pandemic. This decrease was partially offset by a higher average selling price due to growth in the pharmacy channel.

Cost of revenue for the six months ended June 30, 2020 increased $41.3 million, or 36.4%, to $154.9 million, compared with $113.6 million for the six months ended June 30, 2019. Gross margin was 63.5% for the six months ended June 30, 2020, compared with 66.3% for the six months ended June 30, 2019. The 280 basis point decrease in gross margin was primarily due to start-up costs and inefficiencies related to our new U.S. manufacturing operations as well as two months of higher depreciation expense for under-utilized plant capacity, recruiting and screening expenses, expedited shipping costs and manufacturing incentives totaling $6.5 million associated with our contract manufacturer in China as a result of the coronavirus pandemic. This decrease was partially offset by higher average selling price due to growth in the pharmacy channel. We expect full year 2020 gross margin to be approximately 63%, which reflects an estimated $7 to $10 million of costs resulting from the coronavirus pandemic, in addition to start-up costs and inefficiencies as we continue to ramp up our U.S. manufacturing operations, partially offset by continued improvements in our global manufacturing and supply chain operations and the move into the pharmacy channel in the United States.

Research and Development Expenses

Research and development expenses for the three months ended June 30, 2020 increased $1.2 million, or 3.6%, to $34.2 million, compared with $33.0 million for the three months ended June 30, 2019. This increase was primarily due to spend related to Omnipod 5, partially offset by reduced spend on Omnipod DASH, which was launched in the prior year period.

Research and development expenses for the six months ended June 30, 2020 increased $4.2 million, or 6.4%, to $69.7 million, compared with $65.5 million for the six months ended June 30, 2019. This increase was primarily due to spend related to Omnipod 5, partially offset by reduced spend on Omnipod DASH, which was launched in the prior year period. We expect research and development spending for the full year 2020 to increase compared with 2019.

Selling, General and Administrative Expenses

Selling general and administrative expenses for the three months ended June 30, 2020 increased $5.0 million, or 6.6%, to $80.8 million, compared with $75.8 million for the three months ended June 30, 2019. This increase was primarily attributable to investments in initiatives to support our growth, as well as headcount year over year, primarily associated with the expansion of our U.S. sales force. These increases were partially offset by a decrease in travel and entertainment expenses due to reduced activity resulting from COVID-19.

Selling general and administrative expenses for the six months ended June 30, 2020 increased $22 million, or 15.4%, to $164.7 million, compared with $142.7 million for the six months ended June 30, 2019. This increase was primarily attributable to investments in customer support and other initiatives to support our growth, as well as headcount year over year, primarily associated with the expansion of our U.S. sales force. These increases were partially offset by a decrease in travel and entertainment expenses due to reduced activity resulting from COVID-19. We expect selling, general and administrative expenses for the full year 2020 to increase compared with 2019 due to expansion of our U.S. sales force and customer support personnel and investments in our operating structure to facilitate our continued growth.

Non-Operating Items

Interest Expense, Net

Net interest expense increased $5.3 million to $11.1 million for the three months ended June 30, 2020, compared with $5.8 million for the three months ended June 30, 2019. This increase was driven by a $3.4 million increase in non-cash interest expense associated with our 0.375% Notes issued in September 2019, a $1.2 million decrease in interest income due to lower market rates and a shift in a portion of our investment portfolio to more liquid investments and a $1.0 million decrease in capitalized interest primarily due to the placement of our first U.S. manufacturing line into service during the second quarter of 2019.

Net interest expense increased $10.6 million to $21.2 million for the six months ended June 30, 2020, compared with $10.6 million for the six months ended June 30, 2019. This increase was driven by a $6.9 million increase in non-cash interest expense associated with our 0.375% Notes issued in September 2019 and a $2.8 million decrease in capitalized interest primarily due to the placement of our first U.S. manufacturing line into service during the second quarter of 2019, as well as a $1.5 million decrease in interest income due to lower market rates and a shift in a portion of our investment portfolio to more liquid investments.

Other Income, Net

During the three months ended June 30, 2020, we had other income, net of $1.0 million, compared with $0.1 million for the three months ended June 30, 2019. The increase in other income was primarily driven by unrealized foreign currency gains due to the change in exchange rates.

During the six months ended June 30, 2020, we had other income, net of $1.0 million, compared with $2.3 million for the six months ended June 30, 2019, The decrease in other income was primarily driven by a $1.8 million insurance recovery for damaged inventory in excess of our cost received during the six months ended June 30, 2019.

Income Tax Expense, Net

Income tax expense was $3.0 million and $0.5 million for the three months ended June 30, 2020 and 2019, respectively. This resulted in effective tax rates of 17.2% and 25.6% for the three months ended June 30, 2020 and 2019, respectively. The decrease in the effective tax rate was driven by a shift in expected geographic mix of income.

Income tax expense was $2.5 million and $0.8 million for the six months ended June 30, 2020 and 2019, respectively. This resulted in effective tax rates of 17.0% and 12.3% for the six months ended June 30, 2020 and 2019, respectively. The increase in the effective tax rate was driven by a shift in expected geographic mix of income.

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”):

Non-GAAP Financial Measures

Management uses the following non-GAAP financial measures:

Constant currency revenue growth measures the change in revenue between current and prior year periods using a constant currency, 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 accounting principles generally accepted in the United States (“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 and other significant unusual items, 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, securities analysts and other interested parties as a measure of our comparative operating performance from period to period. We recognize Adjusted EBITDA as a commonly used measure in determining business value and as such, use it internally to report results. It is also one of the performance metrics that determines management incentive compensation.

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

As of June 30, 2020, we had $779.1 million in cash and cash equivalents and $88.8 million of investments in marketable securities. 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. As of June 30, 2020, we had $78.7 million in capital commitments.

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 June 30, 2020, the following notes were outstanding:


Issuance Date	Coupon	Principal Outstanding (in millions)		Due Date	Initial Conversion Rate per Share of Common Stock	Conversion Price per Share of Common Stock
November 2017	1.375%	$	402.5	November 2024	10.7315	$	93.2
September 2019	0.375%	800.0		September 2026	4.4105	$	226.7
Total		$	1,202.5

Additional information regarding our debt issuances is provided in Note 8 to the consolidated financial statements.

Summary of Cash Flows

(in millions)	2020		2019
Cash provided by (used in):
Operating activities	$	22.8	$	20.4
Investing activities	80.6		(31.8)

Net increase in cash and cash equivalents	$	565.4	$	6.0

Operating Activities

Net cash provided by operating activities of $22.8 million for the six months ended June 30, 2020 was primarily attributable to net income, as adjusted for non-cash interest, depreciation and amortization, and stock-based compensation, partially offset by a $46.9 million working capital cash outflow driven by a $13.9 million decrease in accounts payable, accrued expenses and other current liabilities, a $14.0 million increase in prepaid expenses and other assets and a $13.8 million increase in accounts receivable. The decrease in accounts payable, accrued expenses and other current liabilities was driven by the annual payout of cash bonuses for performance in the prior year. The increase in prepaid expenses and other assets was driven by an increase unbilled revenue resulting

Table of Contents

from an increase in demand for our Drug Delivery product. The $13.8 million increase in accounts receivable was primarily due to an increase in International Omnipod revenue and sales in the U.S. pharmacy channel, both of which generally have longer payment terms.

Investing Activities

Net cash provided by investing activities was $80.6 million for the six months ended June 30, 2020, compared with net cash used in investing activities of $31.8 million for six months ended June 30, 2019.

Capital Spending—Capital expenditures were $51.7 million for the six months ended June 30, 2020 and primarily related to equipment to increase our manufacturing capacity. Capital expenditures of $91.9 million for the six months ended June 30, 2019 were primarily associated with the construction of our manufacturing and corporate headquarters facility in Acton, Massachusetts. For the full year 2020, we expect capital expenditures to be relatively consistent with 2019 as we continue to expand manufacturing capacity to support our growth and the launch of Omnipod 5 in the first half of 2021. We expect to fund our capital expenditures using a combination of existing cash and investments as well as cash generated from operations.

Purchases and Sales of Investments—Net sales of marketable securities were $132.8 million for the six months ended June 30, 2020, compared with $65.1 million for the six months ended June 30, 2019. The increase in net sales of marketable securities was driven by a shift in a portion of our investment portfolio to investments that are classified as cash equivalents.

Financing Activities

Net cash provided by financing activities was $464.9 million for the six months ended June 30, 2020, compared with net cash provided by financing activities of $17.7 million for six months ended June 30, 2019.

Issuance of Common Stock—During the six months ended June 30, 2020, we sold 2.4 million common shares for $478.7 million in an underwritten registered offering. Net proceeds from the offering were $477.5 million. The proceeds provide us with additional liquidity to mitigate risk and allow us to continue investing in the growth of our business and our strategic initiatives.

Option Exercises and Payment of Taxes for Restricted Stock Net Settlements—Total proceeds from option exercises were $14.2 million and $25.6 million for the six months ended June 30, 2020 and 2019, respectively. The $11.4 million decrease in proceeds from option exercises was primarily driven by the retirement of former executives in the prior year period. Payments for taxes related to net restricted and performance stock unit settlements were $26.8 million and $7.9 million for the six months ended June 30, 2020 and 2019, respectively. The $18.9 million increase in payments for taxes related to restricted stock net settlements was primarily due to a higher achievement percentage on performance stock units vested in the first quarter of 2020 compared to the prior year.

Commitments and Contingencies

Following the expiration of an agreement with a former European distributor on June 30, 2018, we were required to pay a quarterly per-unit fee for Omnipod sales to certain customers of the former European distributor for a one-year period through June 30, 2019. The methodology applicable for determining the total fee under the distribution agreement is subject to an active arbitration proceeding in Switzerland. The final amount of the fee could vary significantly depending on the number of customers who count for purposes of calculating the fee under the terms of the agreement. We estimate that the final aggregate fee for the applicable twelve-month period could be in the range of $5 million to $55 million, of which $5.1 million had been paid as of June 30, 2020.

Legal Proceedings

The significant estimates and judgments related to establishing litigation reserves are discussed under “Legal Proceedings” in Note 9 to the consolidated financial statements included in this Form 10-Q.

Off-Balance Sheet Arrangements

As of June 30, 2020, we had various outstanding letters of credit and bank guarantees totaling $2.9 million, none of which is individually significant. We have restricted cash that serves as collateral for these outstanding letters of credit and bank guarantees that are included in cash and cash equivalents on our consolidated balance sheet.

Critical Accounting Policies and Estimates

The preparation of our consolidated financial statements in conformity with 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.

We believe that our accounting policies for revenue recognition, accounts receivable and allowance for credit losses, product warranty and contingencies are based on, among other things, judgments and assumptions made by management that include inherent risks and uncertainties. There have been no significant changes to the above critical accounting policies or in the underlying accounting assumptions and estimates used in such policies from those disclosed in our annual consolidated financial statements and

Table of Contents

accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2019, except our accounting policy for our allowance for doubtful accounts (now termed allowance for credit losses). As of January 1, 2020, we adopted Accounting Standards Update (“ASU”) 2016-13, Credit Losses (Topic 326), as described in Note 1 to the consolidated financial statements in this Form 10-Q.

Accounting Standards Issued and Not Yet Adopted

In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 eliminates certain exceptions in the current guidance regarding the approach for intraperiod tax allocations, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This new guidance also simplifies the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies such things as the accounting for transactions that result in a step up in the tax basis of goodwill. The guidance is effective for us beginning in the first quarter of 2021 with early adoption permitted. We are currently evaluating the impact of this guidance on our consolidated financial statements.

In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the accounting for convertible instruments by eliminating certain separation models. Under ASU 2020-06, a convertible debt instrument will generally be reported as a single liability at its amortized cost with no separate accounting for embedded conversion features. Consequently, the interest rate of convertible debt instruments will be closer to the coupon interest rate. In addition, ASU 2020-06 eliminates the treasury stock method to calculate diluted earnings per share for convertible instruments and requires the use of the if-converted method. The guidance is effective for us beginning in the first quarter of 2022 with early adoption permitted. The adoption of this standard will have no impact on our diluted earnings per share as we calculate earnings per share using the if-converted method. We are currently evaluating the impact of the remaining provisions on our consolidated financial statements.

The risk factors discussed in “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019 and in this Quarterly Report 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. Actual results could differ materially from those projected in the forward-looking statements; accordingly, you should not rely upon forward-looking statements as predictions of future events. We expressly disclaim any obligation to update these forward-looking statements other than as required by law.

Based on the evaluation, our chief executive officer and chief financial officer concluded that, as of that date, our disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the three months ended June 30, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

Information regarding our material pending legal proceedings, which is incorporated herein by reference, is provided in Note 9 to the consolidated financial statements in this Form 10-Q.

Item 1A. Risk Factors

Please refer to the “Risks Factors” section in our Annual Report on Form 10-K for the year ended December 31, 2019 for a discussion of risks to which our business, financial condition, results of operations and cash flows are subject. Other than as set forth below, there have been no material changes to the risk factors disclosed in the aforementioned Annual Report.

Our financial condition and results of operations have been and may to continue to be adversely affected by the recent coronavirus outbreak.

A novel strain of coronavirus (COVID-19) was identified in China in December 2019, and subsequently declared a pandemic by the World Health Organization in March 2020. To date, this outbreak, which has surfaced in nearly all regions around the world, and preventative measures taken to contain or mitigate the outbreak, have caused, and are continuing to cause, business slowdown or shutdown in affected areas and disruption in the financial markets globally. This has led to a significant increase in unemployment and a loss of employee-sponsored insurance coverage for many people in the United States. As a result, consumers may reduce their spending and our customer attrition rate may increase, which could have a material adverse effect on our business, sales, financial condition and results of operations.

The COVID-19 pandemic also has the potential to significantly impact our supply chain if the manufacturing plants that produce our products or product components, the distribution centers where we manage our inventory, or the operations of our logistics and other service providers, including third parties that sterilize our products, are disrupted, temporarily closed or experience worker shortages for a sustained period of time. Although China, where we manufacture a significant portion of our product, has begun to experience recovery and we are currently producing at pre-COVID-19 levels, should China suffer a COVID-19 relapse, it could hinder our ability to produce product and have a material adverse effect on our business and results of operations.

The further spread of COVID-19, and the requirements to take action to help limit the spread of the illness, may impact our ability to carry out our business as usual. For example, the COVID-19 pandemic may divert healthcare resources away from the conduct of clinical trials and interruption in the operations of the U.S. Food and Drug Administration and comparable foreign regulatory agencies, which could delay product approval timelines. Further, we could experience limitations on employee resources that would otherwise be focused on the conduct of preclinical studies and clinical trials, including because of sickness of employees or their families, the requirement for employees to avoid contact with large groups of people and the reliance on working from home. The continued spread of COVID-19 may also slow potential enrollment of clinical trials, reduce the number of eligible patients for our clinical trials and impact our ability to recruit principal investigators and site staff. As a result of the COVID-19 pandemic, including related governmental guidance or requirements, many of our employees are working from home, which may negatively impact productivity and cause other disruptions to our business. In addition, if the pandemic continues, we may experience a decline in sales activities, which may hinder new patient starts and negatively impact our revenue growth.

The extent of the impact of the COVID-19 pandemic on our business and financial performance, including our ability to execute our near-term and long-term business strategies and initiatives in the expected time frame, will depend on future developments, including the duration and severity of the pandemic, which are uncertain and cannot be predicted. In addition, the pandemic could cause an economic slowdown of potentially extended duration and lead to a global depression. Any sustained disruption in the capital markets from the COVID-19 pandemic could negatively impact our ability to raise capital. If the macro-economic disruption continues for pro-longed periods, we may need to raise additional capital and capital may not be available on acceptable terms, or at all. While we have a strong balance sheet as of June 30, 2020, in part due to the completion of a public offering of common stock in May 2020, and currently do not need to raise additional capital, should the opportunity arise to raise capital on favorable terms, we may choose to do so in order to minimize this risk. We cannot predict when the macro-economic disruption stemming from the coronavirus will ebb or when the economy will return to pre-coronavirus levels, if at all.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings Between May 5, 2015 and June 16, 2015, three class action lawsuits were filed by shareholders in the U.S. District Court, for the District of Massachusetts, against the Company and certain then current and former executives of the Company. Two suits subsequently were voluntarily dismissed. Arkansas Teacher Retirement System v. Insulet, et al., 1:15-cv-12345, (“ATRS”) alleged that the Company (and certain then current and former executives) committed violations of Sections 10(b) and 20(a) and Rule 10b-5 of the Securities Exchange Act of 1934 by making allegedly false and misleading statements about the Company’s business, operations and prospects. On February 8, 2018, the parties executed a binding stipulation of settlement, under which all claims were released, and a payment was made into an escrow account for the plaintiffs and the class they purport to represent. On August 6, 2018, the Court issued an order approving the settlement, but took the plaintiffs’ motion for fees and expenses under advisement, which motion remains pending. The Company had previously accrued fees and expenses in connection with this matter for the amount of the final settlement liability that was not covered by insurance, the amount of which was not material to the Company’s consolidated financial statements. In addition, on April 26, 2017, a derivative action (Walker v. DeSisto, et al., 1:17-cv-10738) (“Walker”) was filed, and on October 13, 2017, a second derivative action (Carnazza v. DeSisto, et al., 1:17-cv-11977) (“Carnazza”) was filed, both on behalf of the Company, each by a shareholder in the U.S. District Court for the District of Massachusetts against the Company (as a nominal defendant) and certain individual then current and former officers and directors of the Company. The allegations in the actions are substantially similar to those alleged in the securities class action. The actions seek, among other things, damages, disgorgement of certain types of compensation or profits, and attorneys’ fees and costs. On July 11, 2018, the parties executed a binding stipulation of settlement, under which all claims were released, and a payment of attorneys’ fees and reimbursement of expenses will be paid to plaintiffs’ counsel, subject to the Court’s approval. On July 13, 2018, the plaintiffs filed a motion for preliminary approval of the settlement, which is pending. The Company expects that such fees and expenses payable to plaintiff’s counsel will be covered by the Company’s insurance. In June 2020, Roche Diabetes Care, Inc. (“Roche”) filed a patent infringement lawsuit against the Company in the United States District Court for the District of Delaware alleging that the Company’s manufacture and sale of its Omnipod Insulin Management System, Omnipod Starter Kit and Omnipod 10 Pod Pack in the United States infringed Roche’s now-expired U.S. Patent 7,931,613. Roche is seeking monetary damages and attorneys’ fees and costs. Since the patent expired in 2019, Roche is not seeking injunctive relief and the lawsuit will have no impact on ongoing sales of the Company’s products. The Company believes that it has meritorious defenses to Roche’s claims and intends to vigorously defend against them. At this time, based on available information regarding this litigation, the Company is unable to reasonably assess the ultimate outcome of this case or determine an estimate, or range of estimates, of potential losses. The court has not yet set a schedule for the case. In July 2020, the Company filed a patent infringement claim against Roche Diabetes Care Limited (“Roche Ltd.”) in the United Kingdom alleging that Roche Ltd.’s manufacture and sale of the Accu-Chek® Solo insulin pump and its consumable components infringes European Patent No. 1 335 764 in the United Kingdom. The Company is seeking an injunction to last until expiry of the patent and monetary damages. The Company is, from time to time, involved in the normal course of business in various legal proceedings, including intellectual property, contract, employment and product liability suits. Other than as described above, the Company does not expect the outcome of these proceedings, either individually or in the aggregate, to have a material adverse effect on its results of operations. Fees to Former European Distributor Following the expiration of an agreement with a former European distributor on June 30, 2018, the Company was required to pay a quarterly per-unit fee for Omnipod sales to certain customers of the former European distributor for a one-year period through June 30, 2019. The Company recognized a liability and an associated intangible asset for this fee as qualifying sales occurred. The methodology applicable for determining the total fee under the distribution agreement is subject to an active arbitration proceeding in Switzerland. The final amount of the fee could vary significantly depending on the number of customers who count for purposes of calculating the fee under the terms of the agreement. The Company estimates that the final aggregate fee is in the range of $5 million to $55 million. As of both June 30, 2020 and December 31, 2019, the Company had $2.7 million accrued related to this matter. The associated gross intangible asset was $7.8 million at both June 30, 2020 and December 31, 2019.

Income Taxes	Jun. 30, 2020
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rate for the three and six months ended June 30, 2020 was 17.2% and 17.0%, compared with 25.6% and 12.3% for the three and six months ended June 30, 2019. Income tax benefits have not been recorded for losses in jurisdictions where valuation allowances exist against net deferred tax assets, primarily in the United States. As of June 30, 2020 and December 31, 2019, the Company maintained a full valuation allowance against its U.S. net deferred tax assets based on the determination that it is not more likely than not these future benefits will be realized. The Company had no uncertain tax positions at both June 30, 2020 and December 31, 2019. In April 2020, new interpretations of a German tax law related to intellectual property and withholding tax were released. The Company is evaluating whether these new interpretations, applicable to corporate multinationals, will have an impact on the consolidated financial statements.
