INSULET CORPORATION

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

Note 1. Nature of the Business

Insulet Corporation (“Insulet”) is primarily engaged in the development, manufacturing and sale of its proprietary Omnipod ® System, an innovative, discreet and easy-to-use continuous insulin delivery system for people with insulin-dependent diabetes. The Omnipod System consists of two product lines: the Omnipod Insulin Management System (“Omnipod”), which Insulet has been selling since 2005, and its next generation Omnipod DASH TM Insulin Management System (“Omnipod DASH” or “DASH”). Insulet began a full market release of Omnipod DASH in the United States at the end of the first quarter of 2019. Collectively, these products are referred to as the “Omnipod System”.

In addition to using the Omnipod System for insulin delivery, Insulet also partners with global pharmaceutical and biotechnology companies to tailor the Omnipod System technology platform for the delivery of their drugs across other therapeutic areas. The majority of Insulet's drug delivery revenue currently consists of sales to Amgen supplying the Neulasta ® Onpro ® kit, an innovative delivery system for Amgen’s white blood cell booster to help reduce the risk of infection during intense chemotherapy.

Note 2 . Basis of Presentation

Basis of Presentation

The accompanying financial statements reflect the consolidated operations of Insulet and its subsidiaries (the “Company”). The unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions in the application of certain of its significant accounting policies that may materially affect the reported amounts of assets, liabilities, equity, revenue 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 nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2019 , or for any other subsequent interim period.

The year-end balance sheet data was derived from audited consolidated financial statements. These consolidated financial statements do not include all of the annual disclosures required by U.S. 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, 2018 .

Shipping and Handling Costs

Shipping and handling costs are included in general and administrative expenses and were $ 2.2 million for both the three months ended September 30, 2019 and 2018 and were $ 7.1 million and $ 4.6 million for the nine months ended September 30, 2019 and 2018 , respectively.

Reclassification of Prior Period Amounts

Certain reclassifications have been made to prior period amounts to conform to the current period financial statement presentation. Software license costs have been reallocated from general and administrative expenses to research and development and sales and marketing expenses based on license usage. These reclassifications have no effect on previously reported net income.

Recently Adopted Accounting Standards

Effective January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 and its related amendments (collectively referred to as ASC 842), which amends the guidance in former ASC Topic 840, Leases. The new standard requires lessees to recognize right-of-use (“ROU”) assets and lease liabilities on the balance sheet for those leases classified as operating leases. The Company adopted ASC 842 on January 1, 2019 using the modified retrospective method, whereby the new guidance is applied prospectively as of the date of adoption and prior periods are not restated. The Company elected the practical expedients that permit the Company to not reassess (1) whether any expired or existing contracts are or contain leases, (2) the lease classification for any expired or existing leases, and (3) any initial direct costs for any existing leases as of the effective date. The Company also excludes leases with an expected term of less than one year from the application of ASC 842. Upon the adoption, the Company recorded ROU assets of $ 8.8 million and operating lease liabilities of $ 10.8 million on its consolidated balance sheet. The difference between the approximate value of the ROU assets and the approximate value of the lease obligations was primarily attributable to a former cease-use liability. See Note 11 for additional information regarding leases.

Effective January 1, 2019, the Company early adopted ASU 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”). ASU 2018-15 requires certain costs to implement a cloud computing arrangement that is a service contract to be capitalized consistent with the rules applicable to internal-use software

Table of Contents

capitalization projects. The Company adopted this new guidance effective January 1, 2019, prospectively. The Company defers eligible costs related to the implementation of cloud computing arrangements within other current and non-current assets and amortizes such costs over the expected term of the hosting arrangement to the same income statement line as the associated cloud operating expenses. Adoption of this standard resulted in the Company capitalizing $ 0.4 million and $ 2.4 million of cloud computing implementation costs for the three and nine months ended September 30, 2019 , respectively.

0.375 % Convertible Senior Notes

In September 2019, the Company issued $ 800.0 million aggregate principal amount of 0.375 % Convertible Senior Notes due September 2026 (the “ 0.375 % Notes”). The interest rate on the notes is 0.375 % per annum, payable semi-annually in arrears in cash in March and September of each year. The 0.375 % Notes are convertible into the Company's common stock at an initial conversion rate of 4.4105 shares of common stock per $1,000 principal amount of the 0.375 % Notes, which is equivalent to a conversion price of approximately $ 226.73 per share, subject to adjustment under certain circumstances. The 0.375 % Notes will be convertible prior to the close of business on the business day immediately preceding June 1, 2026 only under certain circumstances and during certain periods, and will be convertible on or after June 1, 2026 until the close of business on the second scheduled trading day immediately preceding the maturity date (September 1, 2026).

The Company recorded a debt discount of $ 213.0 million related to the 0.375 % Notes resulting from the allocation of a portion of the proceeds to the fair value of the conversion feature reflecting a nonconvertible debt borrowing rate of 5.29 % per annum. This debt discount was recorded as additional paid-in capital and is being amortized as non-cash interest expense over the seven -year term of the 0.375 % Notes. The Company also incurred debt issuance costs and other expenses related to the 0.375 % Notes of approximately $ 19.8 million , of which $ 5.3 million was reclassified as a reduction to the value of the conversion feature allocated to equity. The remaining $ 14.5 million of debt issuance costs is presented as a reduction of debt in the consolidated balance sheet and is being amortized using the effective interest method as non-cash interest expense over the seven year term of the 0.375 % Notes. The net proceeds of $ 780.2 million were used to fund the redemption of the Company's 1.25 % Convertible Senior Notes due September 2021 and for the purchase of capped call options (“Capped Calls”), both of which are discussed below.

The 0.375 % Notes contain provisions that allow for additional interest to holders of the notes upon failure to timely file documents or reports that the Company is required to file with the Securities and Exchange Commission. The additional interest is at a rate of 0.5 % per annum of the principal amounts of the notes outstanding for a period of 360 days . If the Company merges or consolidates with a foreign entity, then additional taxes may be required to be paid by the Company under the terms of the 0.375 % Notes. The Company determined that the higher interest payments required and tax payments required in certain circumstances are considered embedded derivatives and should be bifurcated and accounted for at fair value. The Company assesses the value of the embedded derivatives at each balance sheet date. The derivatives had nominal value at the balance sheet date.

In conjunction with the issuance of the Convertible Senior Notes, the Company paid $ 85.4 million to enter into Capped Calls on the Company’s common stock with certain counterparties, which was recorded as a reduction to additional paid-in capital on the consolidated balance sheet. By entering into the Capped Calls, the Company expects to reduce the potential dilution to its common stock (or, in the event the conversion is settled in cash, to provide a source of cash to settle a portion of its cash payment obligation) in the event that at the time of conversion its stock price exceeds the conversion price under the Convertible Senior Notes. The Capped

Table of Contents

Calls have an initial strike price of $ 335.90 per share, which represents a premium of 100 % over the last reported sale price of the Company’s common stock of $ 167.95 per share on the date of the transaction (September 3, 2019). The Capped Calls cover 3.5 million shares of common stock.

1.25 % Convertible Senior Notes

During the three months ended September 30, 2019 , the Company repurchased $ 225.0 million in principal of 1.25 % Convertible Senior Notes due September 2021 ( $ 202.9 million net of discount and issuance costs) for total consideration of $ 648.0 million . The total consideration was comprised of $ 453.6 million in cash and $ 194.4 million representing the fair value of the 1.16 million shares issued. The Company allocated $ 438.6 million of the settlement to the fair value of the equity component and $ 209.4 million to the debt component, which resulted in a $ 6.5 million loss on extinguishment for both the three and nine months ended September 30, 2019 .

In October 2019, the Company repurchased the remaining $ 120.0 million in principal of 1.25 % Convertible Senior Notes due September 2021 ( $ 108.3 million net of discount and issuance costs) for total consideration of $ 315.0 million . The total consideration was comprised of $ 210.0 million in cash and $ 105.0 million representing the fair value of the 0.7 million shares issued. The Company allocated $ 203.7 million of the settlement to the fair value of the equity component and $ 111.4 million to the debt component, which resulted in a $ 3.1 million loss on extinguishment, which will be recorded during the fourth quarter of 2019.

Note 6. Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period, excluding unvested restricted common shares. Diluted net income (loss) per share is computed using the weighted average number of common shares outstanding and, when dilutive, potential 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 debt (using the if-converted method).

The table below sets forth the components used in the computation of basic and diluted net income (loss) per share for the three and nine months ended September 30, 2019 and 2018. Because the Company reported a net loss for the nine months ended September 30, 2018 , all potential dilutive common shares have been excluded from the computation of the diluted net loss per share for the nine months ended September 30, 2018 , as the effect would have been anti-dilutive.

For the three and nine months ended September 30, 2019 , certain potential outstanding shares from stock options, restricted stock units and convertible debt were excluded from the computation of diluted net income per share because the effect of including these items was anti-dilutive. Additionally, certain performance-based restricted stock units were excluded from the computation of diluted net income per share because the underlying performance conditions for such restricted stock units had not yet been met.

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 goods sold in the consolidated statements of operations. Cost to service the claims reflects the current product cost. A reconciliation of the changes in the Company’s product warranty liability is as follows:

Note 10 . 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 individual 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 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. 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 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.

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. Although the Company is unable to quantify the exact financial impact of any of these matters, the Company believes that none of these currently pending matters will have an outcome material to its financial condition or business.

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 September 30, 2019 the Company had recognized $ 7.8 million for fees related to Omnipod devices sold to qualifying customers during the period from July 1, 2018 through June 30, 2019.

Note 11 . Leases

As discussed in Note 2, ASC 842 requires lessees to recognize ROU assets and lease liabilities on the balance sheet based on the present value of the future minimum lease payments over the lease term at commencement date. As the Company's leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at lease commencement in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

As of September 30, 2019 , the Company leased certain office spaces, laboratory space, warehouse space and automobiles, all of which were classified as operating leases. Certain of the Company's operating leases include escalating rental payments. Some leases include the option to extend for up to 5 years , and some include options to terminate the leases at certain times within the lease term. As of September 30, 2019 , the Company included options to extend that are reasonably certain to be exercised in the operating lease assets and liabilities.

The Company's total operating lease cost, which is recorded in general and administrative expenses in the consolidated statements of operations, was $ 1.2 million and $ 3.0 million for the three and nine months ended September 30, 2019 , respectively. For the three and nine months ended September 30, 2018 , total rental expense was $ 0.9 million and $ 2.6 million , respectively. Cash paid for amounts included in the measurement of lease liabilities was $ 1.0 million and $ 2.6 million for three and nine months ended September 30, 2019 , respectively.

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, 2018 and in this quarterly report.

Overview

We are primarily engaged in the development, manufacturing and sale of our proprietary Omnipod ® System (“Omnipod”), an innovative, discreet and easy-to-use 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 the person’s body. Insulin pump therapy has been shown to provide people with insulin-dependent diabetes with numerous advantages relative to MDI therapy. We estimate that approximately one-third of the Type 1 diabetes population in the United States and less than one-fifth of the Type 1 diabetes population outside of the United States use insulin pump therapy. An even smaller portion of the Type 2 diabetes population in and outside of the United States who are insulin-dependent use insulin pump therapy. The Omnipod System features two discreet, easy-to-use devices: a small, lightweight, self-adhesive disposable tubeless Omnipod device (“Pod”) that is worn on the body for approximately three days at a time; and its wireless companion, the handheld Personal Diabetes Manager (“PDM”). The Omnipod System 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’s unique proprietary design and features allow people with insulin-dependent diabetes to manage their diabetes with unprecedented freedom, comfort, convenience, and ease.

We have been selling the Omnipod since 2005 and currently sell both direct to customers, through distribution partners and most recently through the pharmacy channel. The Omnipod is currently available in multiple countries in Europe, as well as in the United States, Canada and Israel. On July 1, 2018 we assumed all commercial activities (including, among other things, distribution, sales, marketing, training and support) for our Omnipod System across Europe following the expiration of an agreement with our former European distributor.

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 subcutaneous drugs across other therapeutic areas. The majority of our drug delivery revenue currently consists of sales of Pods to Amgen supplying the Neulasta ® Onpro ® kit, an innovative delivery system for Amgen’s white blood cell booster to help reduce the risk of infection during intense chemotherapy.

In June 2018, the FDA cleared our Omnipod DASH TM Insulin Management System (“Omnipod DASH”) for commercial distribution. The Omnipod Dash is our next-generation digital mobile Omnipod platform, featuring a secured Bluetooth enabled Pod and PDM with a touch screen color user interface supported by smartphone connectivity. We began a full market release of Omnipod DASH in the United States at the end of the first quarter of 2019.

During the second quarter of 2019, we began producing product from our new highly-automated manufacturing facility in Acton, Massachusetts. We expect that, following start up related activities, the new facility will allow us to lower our manufacturing costs, increase supply redundancy, add capacity closer to our North American customer base and support growth.

Third Quarter 2019 Revenue Results:

Total revenue increased 27% year over year to $ 192.1 million and consisted of the following:

• U.S. Omnipod revenue of $ 109.5 million , an increase of 34% ;

• International Omnipod revenue of $ 67.7 million , an increase of 35% ; and

• Drug Delivery revenue of $ 14.9 million , a decrease of 21% .

Our long-term financial objective is to sustain profitable growth. We expect our efforts for the remainder of 2019 to focus primarily on product and business model innovation and product development, including the continued roll out of Omnipod DASH, expanding market penetration, working with Medicare, Medicaid and commercial payors and intermediaries to further expand access, and ramping up production at our new, highly automated U.S. manufacturing facility. Achieving these objectives is expected to require additional investments in certain initiatives and personnel, as well as enhancements to our supply chain operation capacity, efficiency and effectiveness.

Revenue

Total revenue for the three months ended September 30, 2019 increased $41.0 million , or 27% , to $192.1 million , compared with the three months ended September 30, 2018 , due to continued growth in our U.S. and International Omnipod revenue. U.S. Omnipod revenue increased $27.5 million , or 34% , to $109.5 million , primarily due to higher volumes driven by growing our customer base, the launch of Omnipod DASH and growth through the pharmacy channel. International Omnipod revenue increased $17.5 million , or 35% , to $67.7 million over the same period in 2018. The growth in International Omnipod revenue was primarily driven by higher volumes as we continue to expand awareness and access to the Omnipod. Drug Delivery revenue decreased $4.0 million , or 21% , to $14.9 million , compared with the three months ended September 30, 2018, as a result of updated production planning with our partner.

Total revenue for the nine months ended September 30, 2019 increased $129.9 million , or 33% , to $528.8 million , compared with the nine months ended September 30, 2018 , due to strong growth in our International and U.S. Omnipod revenue. International Omnipod revenue increased $70.3 million , or 60% , to $187.4 million , primarily due to the continued adoption of our product and more favorable pricing as a result of our shift to direct sales of the Omnipod in Europe in July 2018. U.S. Omnipod revenue increased $63.4 million , or 28% , to $293.6 million , primarily due to higher volumes as we continue to expand awareness of and access to the Omnipod. Drug Delivery revenue decreased $3.7 million , or 7% , to $47.8 million , compared with the nine months ended September 30, 2018 .

For 2019, we expect strong Omnipod revenue growth driven by continued market penetration, partially offset by lower Drug Delivery revenue. Internationally, we expect higher revenues primarily due to increasing sales volume as a result of greater awareness and availability of the Omnipod and more favorable pricing for the first half of the year as a result of our mid-2018 transition to direct sales in Europe. In the U.S., we expect higher revenues primarily due to an increase in sales volume as a result of expanded payor coverage, greater awareness and availability of the Omnipod, the launch of Omnipod DASH, commercial expansion strategies and the move into the pharmacy channel.

Cost of Revenue

Cost of revenue for the three months ended September 30, 2019 increased $ 19.9 million , or 41% , to $ 69.0 million , compared with the same period in 2018 and increased $ 43.6 million , or 31% , to $182.6 million for the nine months ended September 30, 2019 , compared with the same prior year period. These increases in cost of revenue were driven by higher sales volumes as well as start-up costs and inefficiencies related to our new U.S. manufacturing operations, partially offset by continued improvements in manufacturing and supply chain operations.

Gross Margin

Gross margin for the three months ended September 30, 2019 decreased 340 basis points to 64.1% , compared with the same period in 2018 . The decrease in gross margin, which we expected, was primarily due to start-up costs and inefficiencies related to our new U.S. manufacturing operations, partially offset by favorable Omnipod mix from the launch of DASH in the U.S. and the move into the pharmacy channel, as well as favorable customer mix internationally.

Gross margin for the nine months ended September 30, 2019 increased 40 basis points to 65.5% , compared with the same period in 2018 . The increase in gross margin was primarily due to favorable pricing following the expiration of our former distribution agreement in Europe and lower product cost as a result of continued improvements in manufacturing and supply chain operations. As expected, these increases were partially offset by start-up costs and inefficiencies related to our new U.S. manufacturing operations. We expect full year 2019 gross margin to be relatively consistent with 2018, which reflects the benefits of continued improvements in manufacturing and supply chain operations, the full year effect of our mid-2018 transition to direct commercial operations in Europe and the move into the pharmacy channel. This is expected to be offset by start-up costs and inefficiencies as we ramp up our new U.S. manufacturing operations.

Research and Development

Research and development expenses for the three months ended September 30, 2019 increased $8.4 million , or 38% , to $ 30.8 million , compared with the same period in 2018 . This increase was primarily due to an increase in research and development expenses related to Omnipod DASH and our Omnipod Horizon TM automated insulin delivery system.

Research and development expenses for the nine months ended September 30, 2019 increased $ 33.6 million or 55% , to $95.0 million compared with the same prior year period. This increase was primarily due to an increase in research and development expenses related to Omnipod DASH and our Omnipod Horizon TM automated insulin delivery system. Research and development expenses also increased due to engineering and operational costs, such as training and start up activities, associated with our newly constructed U.S. manufacturing facility. We expect research and development spending for the full year 2019 to increase compared with 2018.

Sales and Marketing

Sales and marketing expenses for the three months ended September 30, 2019 increased $11.8 million , or 33% , to $ 47.7 million , compared with the same period in 2018 . This increase was primarily attributable to investments to support the expansion of our U.S. sales force.

Sales and marketing expenses for the nine months ended September 30, 2019 increased $ 31.2 million , or 30% , to $ 136.8 million compared with the same prior year period. This increase was primarily attributable to investments to support our mid-2018 transition to direct sales of Omnipod in Europe as well as the expansion of our U.S. sales force. We expect sales and marketing expenses for the full year 2019 to increase compared with 2018 due to additional expansion of our U.S. sales force and customer support personnel to support our continued growth and the full year effect of our transition to direct sales in Europe.

General and Administrative

General and administrative expenses for the three months ended September 30, 2019 decreased $9.3 million , or 25% , to $ 27.5 million , compared with the same period in 2018 . This decrease was primarily attributable to severance-related charges in the prior year period related to the retirement of our former CEO, including stock based compensation for the acceleration of share-based award vesting, partially offset by increased personnel-related costs related to 2018 hires to support the establishment of our direct operations in Europe.

General and administrative expenses for the nine months ended September 30, 2019 increased $ 0.9 million , or 1% , to $ 82.6 million compared with the same prior year period. This increase was primarily attributable to increased personnel-related costs related to 2018 hires to support the establishment of our direct operations in Europe and increased depreciation related to our new headquarters facility, partially offset by severance-related charges in the prior year period related to the retirement of our former CEO, including stock based compensation for the acceleration of share-based award vesting. We expect general and administrative expenses for 2019 to increase compared with 2018 as we continue to grow our business and make investments in our operating structure to support growth as well as due to the effect of our transition to direct commercial operations in Europe.

Table of Contents

Interest Expense, Net of Portion Capitalized

Interest expense, net, for the three months ended September 30, 2019 increased $2.5 million, or 37%, to $ 9.4 million , compared with the same period in 2018 . This increase was primarily due to non-cash interest expense associated with our new 0.375% Notes.

Interest expense, net for the nine months ended September 30, 2019 increased $1.6 million, or 7%, to $23.6 million compared with the same prior year period. This increase was primarily due to non-cash interest expense associated with our new 0.375% Notes. We expect interest expense for the full year 2019 to increase compared with 2018 due to the interest associated with our new 0.375% Notes.

Loss on Extinguishment of Long-term Debt

During the three and nine months ended September 30, 2019 we incurred a $6.5 million loss on extinguishment of debt related to the repurchase of a portion of our 1.25% Notes.

Other (Expense) Income, Net

Other (expense) income, net for the three months ended September 30, 2019 decreased $1.9 million, to expense of $0.1 million, compared with the same period in 2018 . This decrease was primarily due to unrealized foreign exchange loss.

Other (expense) income, net for the nine months ended September 30, 2019 increased $0.7 million, to $5.9 million compared with the same prior year period. This increase was primarily due to a $1.8 million insurance settlement received, partially offset by unrealized foreign exchange loss.

Liquidity and Capital Resources

As of September 30, 2019 , we had $419.9 million in cash and cash equivalents and $216.6 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.

To lower our manufacturing costs, increase supply redundancy, add capacity closer to our North American customer base and support growth, we constructed a highly-automated manufacturing facility in Acton, Massachusetts, from which we began producing product during the second quarter of 2019. This facility also serves as our global headquarters. Capital expenditures in both 2018 and 2019 were above historic levels due to funding the construction of the Acton facility and related equipment purchases. From the purchase of the facility in late 2016 through September 30, 2019 , capital expenditures for the construction of the Acton facility and related equipment purchases have been approximately $293.6 million . In 2019, we expect to invest additional capital in this facility to support our growth, funded by our existing cash and investments as well as cash generated from operations. As of September 30, 2019 , we had $27.9 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. In September 2019, we issued $800.0 million aggregate principal amount of 0.375% Convertible Senior Notes due September 2026. The net proceeds of $780.2 million were used to fund the redemption of our 1.25% Convertible Senior Notes due September 2021 and for the purchase of 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 its stock price exceeds the conversion price under the Convertible Senior Notes. The Capped Calls have an initial strike price of $335.90 per share, and cover 3.5 million shares of common stock. Note 5 to the consolidated financial statements provides additional information regarding the debt issuance, repayment and Capped Calls.

As of September 30, 2019 , the following notes were outstanding:

Issuance Date	Coupon	Principal Outstanding (in thousands)	Due Date	Initial Conversion Rate per Share of Common Stock	Conversion Price per Share of Common Stock
September 2016	1.250%	$ 119,988	September 2021	17.1332	$58.37
November 2017	1.375%	402,500	November 2024	10.7315	$93.18
September 2019	0.375%	800,000	September 2026	4.4105	$226.73
Total		$ 1,322,488

In October 2019, we repurchased the remaining $120.0 million in principal of 1.25% Convertible Senior Notes due September 2021 ($108.3 million net of discount and issuance costs) for total consideration of $315.0 million. The total consideration was comprised of

Table of Contents

$210.0 million in cash and $105.0 million representing the fair value of the 0.7 million shares issued. We expect to allocate $203.7 million of the settlement to the fair value of the equity component and $111.4 million to the debt component, resulting in a loss on extinguishment of $3.1 million, which will be recorded during the fourth quarter of 2019.

Operating Activities

Net cash provided by operating activities of $51.5 million for the nine months ended September 30, 2019 was primarily attributable to net income, as adjusted for non-cash interest, stock-based compensation, depreciation and amortization, partially offset by a $30.3 million working capital cash outflow driven by an increase in inventories. The increase in inventories was primarily due to an increase in raw materials and work-in-process related to the start up of our U.S. manufacturing plant and an increase in finished goods with the addition of inventory held in Europe.

Net cash provided in operating activities of $5.5 million for the nine months ended September 30, 2018 was primarily attributable to net income, as adjusted for stock-based compensation, non-cash interest, depreciation and amortization, partially offset by a $54.5 million working capital cash outflow. The working capital outflow was driven by a $25.3 million increase in inventories to support higher demand for our product and a $24.6 million increase in accounts and unbilled receivables driven by our shift to direct sale of the Omnipod in Europe and unbilled revenue resulting from the adoption of ASC 606 on January 1, 2018.

Investing Activities

During the nine months ended September 30, 2019 , net cash used in investing activities was $19.6 million , compared with $143.7 million for the nine months ended September 30, 2018 .

Capital Spending —Capital expenditures were $114.6 million and $124.9 million for the nine months ended September 30, 2019 and 2018 , respectively, primarily associated with the construction of our manufacturing and corporate headquarters facility in Acton, Massachusetts . For the full year 2019, we expect capital expenditures to be relatively consistent with 2018 as we continue to expand capacity in our U.S. operations to support our growth and profitability objectives. 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 —During the nine months ended September 30, 2019 , net sales of marketable securities were $101.4 million , compared with net purchases of marketable securities of $16.2 million for the nine months ended September 30, 2018 .

Financing Activities

During the nine months ended September 30, 2019 , net cash provided by financing activities was $275.9 million , compared with net cash used in financing activities of $7.1 million for the nine months ended September 30, 2018 .

Debt Issuance and Repayment —As previously discussed under “Convertible Debt” during the nine months ended September 30, 2019 , we received net proceeds of $780.2 million from the issuance of 0.375% Notes. We used $453.6 million of the proceeds to partially fund the redemption of a portion of our outstanding 1.25% Notes and $85.4 million to purchase Capped Calls. During the nine months ended September 30, 2018 , we paid $6.7 million to settle all of our outstanding 2% Notes.

Option Exercises and Issuance of Shares Under Employee Stock Purchase Plan ( “ ESPP ” ) —Total proceeds from option exercises and issuance of common stock under ESPP were $42.9 million and $13.5 million for the nine months ended September 30, 2019 and 2018 , respectively. Payments for taxes related to net restricted share settlements were $8.2 million and $13.8 million for the nine months ended September 30, 2019 and 2018 , respectively.

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. We 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. We estimate that the final aggregate fee could be in the range of $5 million to $55 million, of which $5.1 million had been paid as of September 30, 2019 .

Refer to Note 11 to the consolidated financial statements included in this Form 10-Q for information regarding our leases.

Legal Proceedings

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

Off-Balance Sheet Arrangements

As of September 30, 2019 , we did not have any off-balance sheet arrangements.

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.

We believe that our accounting policies for revenue recognition, fair value measurements, accounts receivable and allowance for doubtful accounts, inventories, product warranty costs, convertible debt, commitments and contingencies and stock-based compensation 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 accompanying notes included in our Annual Report on Form 10-K filed for the year ended December 31, 2018.

Accounting Standards Issued and Not Yet Adopted

In January 2017, the Financial Accounting Standards Board (“FASB”) issued 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 unit's fair value. The guidance is effective for us beginning in the first quarter of 2020. Early adoption is permitted. We do not expect the adoption of this guidance to impact our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Credit Losses (Topic 326) (“ASU 2016-13”). ASU 2016-13 requires financial assets measured at amortized cost, such as 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 guidance is effective for us beginning in the first quarter of 2020. The adoption of this guidance is expected to increase the level of disclosures related to our trade receivables, but is not expected to have a material impact on our consolidated financial statements.

FORWARD-LOOKING STATEMENTS

This quarterly report on Form 10-Q 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.

The outcomes of the events described in these forward-looking statements are subject to risks, uncertainties and assumptions. These risks and uncertainties include, but are not limited to:

• risks associated with our dependence on our principal product platform, the Omnipod, and our ability to design, develop, manufacture and commercialize future products;

• our ability to reduce production costs and increase customer orders and manufacturing volumes;

• adverse changes in general economic conditions;

• impact of healthcare reform laws;

• our ability to raise additional funds in the future on acceptable terms or at all;

• supply problems or price fluctuations with sole source or third-party suppliers on which we are dependent;

• our inability to secure and retain adequate coverage or reimbursement from third-party payors for the Omnipod or future products and potential adverse changes in reimbursement rates or policies relating to the Omnipod or future products;

• failure of our contract manufacturers or component suppliers to comply with the U.S Food and Drug Administration's quality system regulations;

• the potential violation of the Foreign Corrupt Practices Act or any other international, federal or state laws prohibiting “kickbacks” or protecting the confidentiality of customer health information or other protected personal information, or any challenge to or investigation into our practices under these laws;

• product liability lawsuits that may be brought against us, including stemming from off-label use of our product;

• breaches or failures of our product or information technology systems, including by cyberattack;

• reduced retention rates of our customer base;

• unfavorable results of clinical studies relating to the Omnipod or future products, or the products of our competitors;

• future publication of articles or announcement of positions by diabetes associations or other organizations that are unfavorable to the Omnipod;

• the concentration of substantially all of our manufacturing operations at a single location in China and substantially all of Insulet's inventory at a single location in Massachusetts;

• our ability to attract and retain personnel;

• our ability to manage our growth;

• fluctuations in quarterly results of operations;

• risks related to future sales of our common stock or the conversion of any of our convertible debt;

• anti-takeover provisions in our organizational documents.

The risk factors discussed in “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2018 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

Table of Contents

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.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Our financial instruments consist of cash, cash equivalents, short-term and long-term investments, accounts receivable, accounts payable, accrued expenses, debt and long-term obligations. The primary objectives of our investment strategy are to preserve principal, maintain proper liquidity to meet operating needs and maximize yields. To minimize our exposure to an adverse shift in interest rates, we invest mainly in short-term investments and cash equivalents. We do not believe that a 10% change in interest rates would have a material impact on the fair value of our investment portfolio or our interest income.

As of September 30, 2019 , we had outstanding convertible debt on our consolidated balance sheet of $985.8 million , net of unamortized discount and issuance costs totaling $336.7 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 debt, which is disclosed in Note 5 to the consolidated financial statements, is also impacted by changes in our stock price.

Our business is subject to risks, including, but not limited to: unique economic conditions, changes in political climate, differing tax structures, other regulations and restrictions, and foreign exchange rate volatility. A substantial portion of our operations are located in the United States; however, 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. 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 will continue to monitor and evaluate our internal processes relating to foreign currency exchange, including the potential use of hedging strategies.

Item 4. Controls and Procedures

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 September 30, 2019 . 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 September 30, 2019 , 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 that occurred during the three months ended September 30, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
