DexCom, Inc.
Notes to Condensed Consolidated Financial Statements
(Unaudited)


1. Organization and Significant Accounting Policies


Organization and Business

We are a medical device company primarily focused on the design, development and commercialization of continuous glucose monitoring, or CGM, systems for the management of diabetes and metabolic health by patients, caregivers, and clinicians around the world. Unless the context requires otherwise, the terms “we,” “us,” “our,” the “company,” or “Dexcom” refer to DexCom, Inc. and its subsidiaries.


Basis of Presentation and Principles of Consolidation

We have prepared the accompanying unaudited condensed consolidated financial statements in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial information and with the instructions to Form 10-Q and Article 10 of Securities and Exchange Commission, or SEC, Regulation S-X. Accordingly, they do not include all of the information and disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments, which include only normal recurring adjustments considered necessary for a fair presentation, have been included.

Operating results for the three months ended March 31, 2026 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2026.

These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto for the fiscal year ended December 31, 2025 included in the Annual Report on Form 10-K that we filed with the SEC on February 12, 2026.

These condensed consolidated financial statements include the accounts of DexCom, Inc. and our wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

We have reclassified certain prior period amounts to conform to the current period presentation.

We determine the functional currencies of our international subsidiaries by reviewing the environment where each subsidiary primarily generates and expends cash. For international subsidiaries whose functional currencies are the local currencies, we translate the financial statements into U.S. dollars using period-end exchange rates for assets and liabilities and average exchange rates for each period for revenue, costs and expenses. We include translation-related adjustments in comprehensive income and in accumulated other comprehensive income in the equity section of our condensed consolidated balance sheets. We record gains and losses resulting from transactions with customers and vendors that are denominated in currencies other than the functional currency and from certain intercompany transactions in other income, net in our condensed consolidated statements of operations.


Significant Accounting Policies

There were no material changes during the three months ended March 31, 2026 to our significant accounting policies as described in Note 1 “Organization and Significant Accounting Policies” to the financial statements in Part II, Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.


Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires us to make certain estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and the disclosures made in the accompanying notes. Areas requiring significant estimates include pharmacy rebates, inventory reserves, loss contingencies, and the amount of our worldwide tax provision. Despite our intention to establish accurate estimates and use reasonable assumptions, actual results may differ from our estimates.

Table of Contents


Concentration of Credit Risk

Financial instruments which potentially subject us to concentrations of credit risk consist primarily of cash, cash equivalents, short-term marketable securities, and accounts receivable. We limit our exposure to credit risk by placing our cash and investments with a few major financial institutions. We have also established guidelines regarding diversification of our investments and their maturities that are designed to maintain principal and maximize liquidity. We review these guidelines periodically and modify them to take advantage of trends in yields and interest rates and changes in our operations and financial position. We monitor the creditworthiness of our customers based on historical trends, the financial condition of our customers, and external market factors.


Contract Balances

Contract balances represent amounts presented in our condensed consolidated balance sheets when either we have transferred goods or services to the customer or the customer has paid consideration to us under the contract. These contract balances include accounts receivable and deferred revenue. Payment terms vary by contract type and type of customer and generally range from 30 to 90 days.

As of March 31, 2026 and December 31, 2025, accounts receivable included unbilled amounts of $16.9 million. We expect to invoice and collect all unbilled accounts receivable within twelve months.

We record deferred revenue when cash payments have been received prior to satisfaction of the related performance obligation. Our performance obligations are generally satisfied within twelve months of the initial contract date. As of March 31, 2026 and December 31, 2025, the current deferred revenue balances were not material.


Net Income Per Share

Basic net income per share attributable to common stockholders is calculated by dividing the net income attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted average number of common shares outstanding during the period and, when dilutive, potential common share equivalents.

Potentially dilutive common shares consist of shares issuable from restricted stock units, or RSUs, performance stock units, or PSUs, and our senior convertible notes. Other instruments, including warrants and sales‑based milestones, are evaluated when applicable. Potentially dilutive common shares issuable upon vesting of RSUs and PSUs are determined using the average share price for each period under the treasury stock method. Potentially dilutive common shares issuable upon conversion of our senior convertible notes are determined using the if-converted method.

The following table sets forth the computation of basic and diluted net income per share:



	Three Months Ended March 31,
(In millions, except per share data)	2026		2025
Net income	$	199.5	$	105.4
Add back interest expense, net of tax attributable to assumed conversion of senior convertible notes	1.6		2.9
Net income - diluted	$	201.1	$	108.3

Net income per common share
Basic	$	0.52	$	0.27
Diluted	$	0.51	$	0.27

Basic weighted average shares outstanding	385.1		391.1
Dilutive potential securities:


RSUs and PSUs	0.8		0.7
Senior convertible notes	7.7		15.7

Diluted weighted average shares outstanding	393.6		407.5

Outstanding anti-dilutive securities not included in the calculations of diluted net income per share attributable to common stockholders were as follows:

Recent Accounting Guidance

Recently Adopted Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-04, Debt-Debt with Conversion and Other Options. The ASU clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. The ASU is effective for annual reporting periods beginning after December 15, 2025, and interim periods within those annual reporting periods, with early adoption permitted. The ASU may be applied on either a prospective or a retrospective basis. We adopted this standard in the first quarter of 2026 on a prospective basis and there was no material impact on our condensed consolidated financial statements.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses. The ASU requires disaggregated disclosure of certain costs and expenses in the notes to the financial statements. The ASU is effective for annual reporting periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. The ASU may be applied on either a prospective or a retrospective basis. We are currently evaluating the impact of this standard on our disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting. The ASU clarifies interim disclosure requirements and the applicability of Topic 270. The ASU is effective for annual reporting periods beginning after December 15, 2027, and interim periods within those annual reporting periods, with early adoption permitted. The ASU may be applied on either a prospective or a retrospective basis. We are currently evaluating the impact of this standard on our disclosures.

2. Fair Value Measurements

Assets and Liabilities Measured at Fair Value on a Recurring Basis

We estimate the fair values of our Level 1 financial instruments, which are in active markets, using unadjusted quoted market prices for identical instruments.

We obtain the fair values of our Level 2 financial instruments, which are not in active markets, from a primary professional pricing source that uses quoted market prices for identical or comparable instruments, rather than direct observations of quoted prices in active markets. Fair values obtained from this professional pricing source can also be based on pricing models whereby all significant observable inputs, including maturity dates, issue dates, settlement dates, benchmark yields, reported trades, broker-dealer quotes, issue spreads, benchmark securities, bids, offers or other market related data, are observable or can be derived from, or corroborated by, observable market data for substantially the full term of the asset.

We estimate the fair values of our Level 3 financial instruments based on unobservable inputs and other estimation techniques due to the absence of quoted market prices and inherent lack of liquidity.

The following table summarizes financial assets that we measured at fair value on a recurring basis as of March 31, 2026, classified in accordance with the fair value hierarchy:

Foreign Currency and Derivative Financial Instruments

As we conduct business globally in many currencies, we are exposed to foreign exchange rate changes. To limit this exposure, we enter into foreign currency forward contracts to hedge monetary assets and liabilities, including intercompany loans, denominated in non-functional currencies. Our foreign currency forward contracts are not designated as hedging instruments. Therefore, changes in the fair values of these contracts are recognized in earnings, thereby offsetting the current earnings effect of the related foreign currency assets and liabilities. The duration of these contracts are generally one to six months. The derivative gains and losses are included in other income, net in our condensed consolidated statements of operations.

As of March 31, 2026 and December 31, 2025, the notional amounts of outstanding foreign currency forward contracts were $252.4 million and $229.3 million, respectively. The resulting impact on our condensed consolidated financial statements from currency hedging activities was not significant for the three months ended March 31, 2026 and March 31, 2025.

We monitor the costs and the impact of foreign currency risks upon our financial results as part of our risk management program. We do not use derivative financial instruments for speculation or trading purposes or for activities other than risk management. We do not require and are not required to pledge collateral for these financial instruments and we do not carry any master netting arrangements to mitigate the credit risk.

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

In accordance with authoritative guidance, we measure certain non-financial assets and liabilities at fair value on a non-recurring basis. These measurements are usually performed using the discounted cash flow method or cost method and Level 3 inputs. These include items such as non-financial assets and liabilities initially measured at fair value in a business combination and non-financial long-lived assets measured at fair value for an impairment assessment. In general, non-financial assets, including goodwill, intangible assets, and property and equipment, are measured at fair value when there are indicators of impairment and are recorded at fair value only when an impairment is recognized.

Table of Contents

Our non-marketable equity investments without readily determinable fair values are accounted for under the measurement alternative. As such, we measure these investments at cost less impairment, adjusted for any observable price changes in orderly transactions for the identical or a similar investment of the same issuer. It is impracticable for us to estimate the fair value of these investments on a recurring basis due to the fact that these entities are privately held and limited information is available. We include the carrying values of these investments in other assets in our condensed consolidated balance sheets. Adjustments to the carrying values of these investments as a result of observable price changes and impairments are recorded in other income, net in our condensed consolidated statements of operations.

The carrying values of our non-marketable equity investments were $219.5 million as of March 31, 2026 and $218.0 million as of December 31, 2025. During the three months ended March 31, 2026 and March 31, 2025, we did not record any upward adjustments.

For our non-marketable equity investments held as of March 31, 2026, the cumulative upward adjustments for observable price changes were $82.5 million and cumulative downward adjustments and impairments were not significant.

During the three months ended March 31, 2026 and March 31, 2025, net unrealized gains (losses) on non-marketable equity investments were not significant.

There were no significant impairment losses on assets and liabilities measured at fair value on a non-recurring basis during the three months ended March 31, 2026 and March 31, 2025.

As of March 31, 2026, the estimated market values of our short-term debt securities with contractual maturities up to 12 months and up to 18 months were $1.08 billion and $212.2 million, respectively. As of December 31, 2025, the estimated market value of our short-term debt securities with contractual maturities up to 12 months was $1.08 billion. Gross realized gains and losses on sales of our short-term debt securities for the three months ended March 31, 2026 and March 31, 2025 were not significant.

We periodically review our portfolio of debt securities to determine if any investment is impaired due to credit loss or other potential valuation concerns. For debt securities where the fair value of the investment is less than the amortized cost basis, we have assessed at the individual security level for various quantitative factors including, but not limited to, the nature of the investments, changes in credit ratings, interest rate fluctuations, industry analyst reports, and the severity of impairment. Unrealized losses on available-for-sale debt securities at March 31, 2026 were primarily due to changes in interest rates, including market credit spreads, and not due to increased credit risks associated with specific securities. Accordingly, we have not recorded an allowance for credit losses. We do not intend to sell these investments and it is not more likely than not that we will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity.

(1) Net proceeds are calculated by deducting the initial purchasers’ discounts and estimated costs directly related to the offering from the aggregate principal amount of the applicable series of notes.

(2) Subject to adjustments as defined in the applicable indentures.

(3) The 2028 Notes may be settled upon conversion in cash, stock, or a combination thereof, solely at our discretion.

We use the if-converted method for assumed conversion of our senior convertible notes to compute the weighted average shares of common stock outstanding for diluted earnings per share.

No principal payments are due on any of our senior convertible notes prior to maturity. Other than restrictions relating to certain fundamental changes and consolidations, mergers or asset sales and customary anti-dilution adjustments, the indentures relating to our senior convertible notes include customary terms and covenants, including certain events of default after which the senior convertible notes may be due and payable immediately.

2028 Capped Call Transactions

In May 2023, in connection with the offering of the 2028 Notes, we entered into privately negotiated capped call transactions, or the 2028 Capped Calls, with certain financial institutions. The 2028 Capped Calls cover, subject to anti-dilution adjustments substantially similar to those applicable to the 2028 Notes, the number of shares of our common stock initially underlying the 2028 Notes. The 2028 Capped Calls are expected generally to reduce potential dilution to our common stock upon conversion of the 2028 Notes and/or offset any cash payments that we are required to make in excess of the principal amount of converted 2028 Notes, as the case may be, with such reduction and/or offset subject to a cap. The 2028 Capped Calls have an initial cap price of $212.62 per share, subject to adjustments, which represents a premium of 80% over the closing price of our common stock of $118.12 per share on the Nasdaq Global Select Market on May 2, 2023. The cost to purchase the 2028 Capped Calls of $101.3 million was recorded as a reduction to additional paid-in capital in our condensed consolidated balance sheets as the 2028 Capped Calls met the criteria for classification in stockholders’ equity.

Conversion Rights for Senior Convertible Notes

Holders of our outstanding senior convertible notes have the right to require us to repurchase for cash all or a portion of their notes at 100% of their principal amount, plus any accrued and unpaid interest, upon the occurrence of a fundamental change (as defined in the applicable indenture relating to the notes). We are also required to increase the conversion rate for holders who convert their notes in connection with certain fundamental changes occurring prior to the maturity date or following the delivery by Dexcom of a notice of redemption.

Table of Contents

The following table outlines the conversion options related to our 2028 Notes:


Summary of Conversions Rights at the Option of the Holders for the 2028 Notes, or the Notes

Conversion Rights at the Option of the Holders						Holders of the Notes have the ability to convert all or a portion of their notes in multiples of $1,000 principal amount, at their option prior to 5:00 p.m., New York City time, on the business day immediately preceding February 15, 2028 for the 2028 Notes only under the following circumstances:

Circumstance 3						If we call any or all of the Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date (only with respect to the notes called or deemed called for redemption)


Circumstance 4						Upon the occurrence of specified corporate events

(2) Circumstance 5 is available on or after February 15, 2028 for the 2028 Notes.


Summary of Conversion Right at the Option of the Company for the 2028 Notes

Conversion Right at Our Option(1)						Dexcom may redeem for cash all or part of the Notes, at its option, if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which Dexcom provides notice of redemption. The redemption price will be equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest to, but excluding, the redemption date

Amended Credit Agreement

Terms of the Amended Credit Agreement

In June 2023, we entered into the First Amendment to the Second Amended and Restated Credit Agreement, as amended, or the Amended Credit Agreement, which we had previously entered into in October 2021. The Amended Credit Agreement is a five-year revolving credit facility, or the Credit Facility, that provides for an available principal amount of $200.0 million which can be increased up to $500.0 million at our option subject to customary conditions and approval of our lenders. The Amended Credit Agreement will mature on October 13, 2026. Borrowings under the Amended Credit Agreement are available for general corporate purposes, including working capital and capital expenditures.

The following table sets forth information related to availability and outstanding borrowings on our Amended Credit Agreement as of March 31, 2026:



(In millions)
Available principal amount	$	200.0
Letters of credit sub-facility	25.0
Outstanding borrowings	—
Outstanding letters of credit	8.8
Total available balance	$	191.2

Revolving loans under the Amended Credit Agreement bear interest at our choice of one of three base rates plus a range of applicable rates that are based on our leverage ratio. The minimum and maximum range of applicable rates per annum with respect to any ABR Loan, Term Benchmark Revolving Loan, or RFR Revolving Loan, each as defined in the Amended Credit Agreement under the captions “ABR Spread”, “Term Benchmark”, and “RFR Spread”, or “Unused Commitment Fee Rate”, respectively, are outlined in the following table:


Range	ABR Spread	Term Benchmark/RFR Spread	Unused Commitment Fee Rate
Minimum	0.375%	1.375%	0.175%
Maximum	1.000%	2.000%	0.250%

Our obligations under the Amended Credit Agreement are guaranteed by our existing and future wholly-owned domestic subsidiaries, and are secured by a first-priority security interest in substantially all of the assets of Dexcom and the guarantors, including all or a portion of the equity interests of our domestic subsidiaries and first-tier foreign subsidiaries but excluding real property and intellectual property (which is subject to a negative pledge). The Amended Credit Agreement contains covenants that limit certain indebtedness, liens, investments, transactions with affiliates, dividends and other restricted payments, subordinated indebtedness and amendments to subordinated indebtedness documents, and sale and leaseback transactions of Dexcom or any of its domestic subsidiaries. The Amended Credit Agreement also requires us to maintain a maximum leverage ratio and a minimum fixed charge coverage ratio. We were in compliance with these covenants as of March 31, 2026.

As of March 31, 2026, we have other guarantee facilities related to certain international operations that are partially collateralized, which are included in non-current “Other assets” on our condensed consolidated balance sheets. These facilities are not significant to the condensed consolidated financial statements.

5. Contingencies


Litigation

We are subject to various claims, complaints and legal actions that arise from time to time in the normal course of business, including commercial insurance, product liability, intellectual property and employment related matters. In addition, from time to time we may bring claims or initiate lawsuits against various third parties with respect to matters arising out of the ordinary course of our business, including commercial and employment related matters.

Due to uncertainty surrounding the securities class action litigation, the derivative actions, and the G6 and G7 Class Action Litigation, we are unable to reasonably estimate the ultimate outcome of any of the litigation matters at this time. We intend to defend against these claims vigorously in all of these actions.

We do not believe we are party to any other currently pending legal proceedings, the outcome of which could have a material adverse effect on our business, financial condition, or results of operations. There can be no assurance that existing or future legal proceedings arising in the ordinary course of business or otherwise will not have a material adverse effect on our business, financial condition, or results of operations.


6. Income Taxes

We estimate our annual effective tax rate to be 22.7% for the full year 2026, which differs from the U.S. federal statutory rate due to state and foreign income taxes, federal taxation of international operations, and nondeductible executive compensation, partially offset by federal tax credits generated. Our actual effective tax rate of 26.0% for the three months ended March 31, 2026 compared to the estimated annual effective tax rate of 22.7%, was higher primarily due to shortfalls recognized for employee share-based compensation, net of disallowed executive compensation.

The Organization for Economic Co-operation and Development’s, or OECD, Pillar Two Initiative introduced a 15% global minimum tax for certain multinational groups exceeding minimum annual global revenue thresholds. As of March 31, 2026, the global minimum tax rules enacted in countries in which we operate, including the transitional safe harbor provisions, do not have a material impact on our condensed consolidated financial statements.

7. Stockholders’ Equity

Share-Based Compensation

Our share-based compensation expense is associated with RSUs, PSUs, and our Employee Stock Purchase Plan, or ESPP. The following table summarizes our share-based compensation expense included in our condensed consolidated statements of operations:



	Three Months Ended March 31,
(In millions)	2026		2025
Cost of sales	$	2.8	$	3.2
Research and development	11.6		12.8
Selling, general and administrative	28.9		18.2
Total share-based compensation expense	$	43.3	$	34.2

As of March 31, 2026, unrecognized estimated compensation costs related to RSUs and PSUs totaled $312.0 million and are expected to be recognized over a weighted-average period of approximately 2.4 years.

Share Repurchase Program and Treasury Shares

In April 2025, our Board of Directors authorized and approved a share repurchase program of up to $750.0 million of our outstanding common stock, with a repurchase period ending no later than June 30, 2026, or the 2025 Share Repurchase Program. Repurchases of our common stock under the 2025 Share Repurchase Program may be made from time to time in the open market, in privately negotiated transactions or by other methods, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, at our discretion, and in accordance with the limitations set forth in Rule 10b-18 promulgated under the Exchange Act and other applicable federal and state laws and regulations. The timing of any repurchases will depend on market conditions and will be made at our discretion. The 2025 Share Repurchase Program does not obligate us to repurchase any dollar amount or number of shares of our common stock, and the program may be extended, modified, suspended, or discontinued at any time.

During the three months ended March 31, 2026, we did not repurchase any shares of our common stock under the 2025 Share Repurchase Program. During the twelve months ended December 31, 2025, we repurchased 7.7 million shares of our common stock for $500.0 million under the 2025 Share Repurchase Program.

During the three months ended March 31, 2026, 0.5 million of common shares were withheld to satisfy employee tax withholding obligations related to net share settlement.

Repurchased shares of our common stock are held as treasury shares until they are reissued or retired. We have not yet determined the ultimate disposition of repurchased shares and consequently we continue to hold them as treasury shares rather than retiring them. Authorization of future stock repurchase programs is subject to the final determination of our Board of Directors.

8. Business Segment and Geographic Information

We manage our business on a global consolidated basis within one operating and one reportable segment, which is consistent with how our chief operating decision maker (CODM), our President and Chief Executive Officer, reviews our business, makes investment and resource allocation decisions, and assesses operating performance. The majority of our revenue is generated in the United States. Our reportable segment derives revenues from the sale of disposable sensors and our Reusable Hardware.

The measures of segment profit or loss that are most consistent with U.S. GAAP used by the CODM to assess performance and allocate resources are operating income and net income. Our CODM also reviews total assets, as reported on our condensed consolidated balance sheets, and purchases of property and equipment, as reported on our condensed consolidated statements of cash flows.

Our CODM uses operating income and net income to evaluate income generated from segment assets (return on assets) in deciding whether to reinvest profits into the Company, monitor budget versus actual results, acquire companies, or invest in other companies.

The following table sets forth our segment information for revenue, measures of segment profit or loss, and significant expenses:

Revenue by Customer Sales Channel and Geographic Region

We sell our CGM systems through a direct sales organization and through distribution arrangements that allow distributors to sell our products. We also disaggregate our revenue by our two primary geographical markets, the United States and International, based on the geographic location to which we deliver the components.

The following table presents our revenue disaggregated by major sales channel and geographic region:




	Three Months Ended March 31,
	2026						2025
(In millions)	United States		International		Total		United States		International		Total
Distributor	$	796.9	$	213.4	$	1,010.3	$	720.6	$	159.4	$	880.0
Direct	35.4		146.2		181.6		29.9		126.1		156.0
Total revenue	$	832.3	$	359.6	$	1,191.9	$	750.5	$	285.5	$	1,036.0

During the three months ended March 31, 2026, and March 31, 2025, no individual country outside the United States generated revenue that represented more than 10% of our total revenue.

Overview


			Who We Are
			We are a medical device company primarily focused on the design, development and commercialization of continuous glucose monitoring, or CGM, systems for the management of diabetes and metabolic health by patients, caregivers, and clinicians around the world. We received approval from the Food and Drug Administration, or FDA, and commercialized our first product in 2006. We launched our latest generation systems, the Dexcom G7 Continuous Glucose Monitoring System, or G7, in 2023, and the Dexcom G7 15 Day Continuous Glucose Monitoring System, or G7 15 Day, in late 2025. In August 2024, we launched Stelo, our biosensor designed for adults with prediabetes and Type 2 diabetes who do not use insulin, as the first over-the-counter glucose biosensor in the U.S. Unless the context requires otherwise, the terms “we,” “us,” “our,” the “company,” or “Dexcom” refer to DexCom, Inc. and its subsidiaries.


			Global Presence
			We have built a direct sales organization in North America and certain international markets to call on health care professionals, such as endocrinologists, physicians and diabetes educators, who can educate and influence patient adoption of continuous glucose monitoring. To complement our direct sales efforts, we have entered into distribution arrangements in North America and several international markets that allow distributors to sell our products.


			Future Developments
			Product Development: We plan to develop future generations of technologies that are focused on improved performance and convenience and that will enable intelligent insulin administration. Over the longer term, we plan to continue to develop and improve networked platforms with open architecture, connectivity and transmitters capable of communicating with other devices. We also intend to expand our efforts to accumulate CGM patient data and metrics and apply predictive modeling and machine learning to generate interactive CGM insights that can inform patient behavior.


			Partnerships: We continue to support partnerships with insulin pump companies and companies or institutions developing insulin delivery systems, including automated insulin delivery systems. With the introduction of Stelo, we are also pursuing and supporting development partnerships with consumer technology product companies that seek to provide metabolic health insights to their customers.


			New Opportunities: We are also exploring how to extend our offerings to other opportunities, including for people with pre-diabetes, people who are obese, people who are pregnant, and people in the hospital setting. Eventually, we may apply our technological expertise to products beyond glucose monitoring.

Critical Accounting Estimates

The discussion and analysis of our financial condition and results of operations are based on our condensed consolidated financial statements, which we have prepared in accordance with GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements as well as the reported revenue and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and judgments. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We believe that the estimates, assumptions and judgments involved in the accounting policies described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, have the greatest potential impact on our financial statements, so we consider them to be our critical accounting policies and estimates. There were no material changes to our critical accounting estimates during the three months ended March 31, 2026.

Revenue

We generate our revenue from the sale of disposable sensors and our reusable transmitter and receiver, collectively referred to as Reusable Hardware. We expect that the revenue we generate from the sales of our products will fluctuate from quarter to quarter. We typically experience seasonality, with lower sales in the first quarter of each year compared to the immediately preceding fourth quarter. This seasonal sales pattern relates to U.S. annual insurance deductible resets and unfunded flexible spending accounts.

Cost of sales

Cost of sales includes direct labor and materials costs related to each product sold or produced, including assembly, test labor and scrap, as well as factory overhead supporting our manufacturing operations. Factory overhead includes facilities, material procurement and control, manufacturing engineering, quality assurance, supervision and management. These costs are primarily salary, fringe benefits, share-based compensation, facility expense, supplies and purchased services. All of our manufacturing costs are included in cost of sales. In addition, amortization of certain licensing related intangibles are also included in cost of sales.

Research and development

Our research and development expenses primarily consist of engineering and research expenses related to our sensing technology, clinical trials, regulatory expenses, quality assurance programs, employee compensation, and business process outsourcers.

Selling, general and administrative

Our selling, general and administrative expenses primarily consist of employee compensation for our executive, financial, sales, marketing, information technology and administrative functions. Other significant expenses include commissions, marketing and advertising, IT software license costs, insurance, professional fees for our outside legal counsel and independent auditors, litigation expenses, patent application expenses and consulting expenses.

Other income, net

Other income, net consists primarily of interest and dividend income on our cash, cash equivalents and short-term marketable securities portfolio, foreign currency transaction gains and losses resulting from the effects of foreign currency fluctuations, realized and unrealized gains and losses on marketable and non-marketable equity investments, including changes in fair value, and interest expense related to our senior convertible notes.

						Three Months Ended March 31, 2026 Compared to Three Months Ended March 31, 2025

Revenue						The revenue increase was primarily driven by increased sales volume of our disposable sensors due to the continued growth of our worldwide customer base. We added approximately 600,000 to 700,000 net customers, excluding Stelo customers, to our worldwide customer base in 2025. The increase was offset by pricing headwinds due to channel mix and rebate eligibility.


Cost of sales & Gross profit						The increase in gross profit and gross profit margin percentage in the first quarter of 2026 compared to the first quarter of 2025 was primarily driven by increased sales volume, improved manufacturing efficiencies, higher production volumes, and a more favorable manufacturing mix, which resulted in better absorption of fixed costs. The increase in gross margin was attributable to the implementation of additional quality testing and material validation efforts relative to the prior year. Cost of sales decreased primarily as a result of these efficiencies.

Table of Contents



						Three Months Ended March 31, 2026 Compared to Three Months Ended March 31, 2025

Research and development expense						Research and development expense was relatively flat due to the timing of project spend. We continue to believe that focused investments in research and development are critical to our future growth and competitive position in the marketplace, and to the development of new and enhanced products and services that are central to our core business strategy.





Selling, general and administrative expense						Selling, general and administrative expense increased primarily due to $15.9 million in higher compensation and related costs and $15.1 million in incremental investments in advertising and marketing costs.


Other income, net						Other income, net, decreased primarily due to $9.0 million in lower interest and dividend income driven by a decrease in the average invested balances and changes in market interest rates.


Income tax expense						The income tax expense recorded for the three months ended March 31, 2026 and March 31, 2025 was primarily attributable to income tax expense from normal, recurring operations increased by discrete impact of shortfalls recognized for share-based compensation for employees, net of nondeductible executive compensation. The decrease in our effective tax rate for the three months ended March 31, 2026 compared to the same period in 2025 is primarily attributable to the commencement of our Malaysia tax holiday and higher pretax income in the current period.

Liquidity and Capital Resources


Overview, Capital Resources, and Capital Requirements

Our principal sources of liquidity are our existing cash, cash equivalents and marketable securities, cash generated from operations, proceeds from our senior convertible notes issuances, and access to our Credit Facility. Our primary uses of cash have been for research and development programs, selling and marketing activities, capital expenditures, acquisitions of businesses, and debt service costs.

We expect that cash provided by our operations may fluctuate in future periods as a result of a number of factors, including fluctuations in our operating results, working capital requirements and capital deployment decisions. We have historically invested our cash primarily in U.S. dollar-denominated, investment grade, highly liquid obligations of U.S. government agencies, commercial paper, corporate debt, and money market funds. Certain of these investments are subject to general credit, liquidity and other market risks. The general condition of the financial markets and the economy may increase those risks and may affect the value and liquidity of investments and restrict our ability to access the capital markets.

Our future capital requirements will depend on many factors, including but not limited to:

The evolution of the international expansion of our business and the revenue generated by sales of our approved products and any future products;

Our ability to efficiently scale our operations to meet demand for our current and any future products;

The success of our research and development efforts;

The expenses we incur in manufacturing, developing, selling and marketing our products;

The costs, timing and risks of delays of additional regulatory approvals;

The costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;

The quality levels of our products and services;

The emergence of competing or complementary technological developments;

The terms and timing of any collaborative, licensing and other arrangements that we may establish; and

The third-party reimbursement of our products for our customers;

The rate of progress and cost of our clinical trials and other development activities;

The acquisition of businesses, products and technologies and our ability to integrate and manage any acquired businesses, products and technologies.

We expect that existing cash and short-term investments and cash flows from our future operations will generally be sufficient to fund our ongoing core business. As current borrowing sources become due, we may be required to access the capital markets for additional funding. As we assess inorganic growth strategies, we may need to supplement our internally generated cash flow with outside sources. In the event that we are required to access the debt market, we believe that we will be able to secure reasonable borrowing rates. As part of our liquidity strategy, we will continue to monitor our current level of earnings and cash flow generation as well as our ability to access the market in light of those earning levels.

A substantial portion of our operations are located in the United States, and the majority of our sales since inception have been made in U.S. dollars. As we continue to expand internationally, we will be subject to additional foreign exchange currency risk. See “Foreign Currency Exchange Risk” in Part II, Item 7A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, for more information.

Main Sources of Liquidity

Cash, cash equivalents and short-term marketable securities

Our cash, cash equivalents and short-term marketable securities totaled $2.42 billion as of March 31, 2026. None of those funds were restricted and $2.10 billion (approximately 87%) of those funds were located in the United States.

Cash flows from Operations

For the three months ended March 31, 2026, we had positive cash flows of $525.6 million from operating activities. We anticipate that we will continue to generate positive cash flows from operations for the foreseeable future.

Senior Convertible Notes

We received net proceeds of $1.23 billion in May 2023 from the 2028 Notes offering. We used $289.9 million of the net proceeds from the offering of the 2028 Notes to purchase capped call transactions and repurchase shares of our common stock in May 2023. We intend to use the remainder of the net proceeds for general corporate purposes and capital expenditures, including working capital needs. We may also use the net proceeds to expand our current business through in-licensing or acquisitions of, or investments in, other businesses, products or technologies; however, we do not have any significant commitments with respect to any such acquisitions or investments at this time.

In connection with the 2028 Notes offering, we purchased the 2028 Capped Calls. See Note 4 “Debt” to the condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for more information about our senior convertible notes and the 2028 Capped Calls.

Amended Credit Agreement

As of March 31, 2026, we had no outstanding borrowings, $8.8 million in outstanding letters of credit, and a total available balance of $191.2 million under the Amended Credit Agreement. We monitor counterparty risk associated with the institutional lenders that are providing the Credit Facility. We currently believe that the Credit Facility will be available to us should we choose to borrow under it. Revolving loans will be available for general corporate purposes, including working capital and capital expenditures. See Note 4 “Debt” to the condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for more information on the Amended Credit Agreement.

Short-term Liquidity Requirements

As of March 31, 2026, our short-term liquidity requirements primarily consist of regular operating costs, interest payments related to our 2028 Notes, capital expenditures for the development of our manufacturing facilities and office spaces, and short-term material cash requirements as described below. As of March 31, 2026, we had a working capital ratio of 1.95 and a quick ratio of 1.58, which indicates that our current assets are sufficient to cover our short-term liabilities. We expect to incur significant capital expenditures for the next year as we continue to invest in equipment and our manufacturing facilities.

We believe that our cash, cash equivalents, and marketable securities balances, projected cash contributions from our commercial operations, and borrowings under our Credit Facility will be sufficient to meet our anticipated seasonal working capital needs, all capital expenditure requirements, material cash requirements as described herein, and meet other liquidity requirements associated with our operations for at least the next 12 months. We may continue to use cash to repurchase shares of our common stock, including pursuant to the 2025 Share Repurchase Program, or for other strategic initiatives that strengthen our foundation for long-term growth.

Long-term Liquidity Requirements

Our long-term liquidity requirements primarily consist of interest and principal payments related to our 2028 Notes, capital expenditures for the development of our manufacturing facilities and office spaces, and long-term material cash requirements as described below. As of March 31, 2026, we had a debt-to-assets ratio of 0.19, which indicates that our total assets are sufficient to cover our debts. As demand grows for our products, we will continue to expand global operations to meet demand through investments in manufacturing and operations. We expect to meet our long-term liquidity requirements from our main sources of liquidity as described above to support our future operations, capital expenditures, acquisitions, and other liquidity requirements associated with our operations beyond the next 12 months.

Table of Contents

As of March 31, 2026, we have outstanding senior convertible notes classified as long-term that will mature in May 2028. However, the outstanding principal of our senior convertible notes could be converted into cash and/or shares of our common stock prior to maturity once certain conditions are met. See Note 4 “Debt—Senior Convertible Notes” to the condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for information on conversion rights prior to maturity.

Material Cash Requirements

From time to time in the ordinary course of business, we enter into a variety of purchase arrangements including but not limited to, purchase arrangements related to capital expenditures, components used in manufacturing, and research and development activities. As of March 31, 2026, there were no material changes to our contractual obligations outside the ordinary course of business.

Our obligations under the 2028 Notes include both principal and interest payments. Prior to the maturity of the 2028 Notes in May 2028, the notes may be converted into cash and/or shares of our common stock if certain conditions are met. Any conversion prior to maturity may result in repayment of the principal amounts due under the 2028 Notes sooner than the scheduled repayment.

As market conditions warrant, we may, from time to time, repurchase our outstanding debt securities or shares of our common stock, including pursuant to the 2025 Share Repurchase Program, in the open market, in privately negotiated transactions, by exchange transaction or otherwise. Such repurchases, if any, will depend on prevailing market conditions, our liquidity and other factors and may be commenced or suspended at any time. The amounts involved and total consideration paid may be material. See Note 7 “Stockholders’ Equity—Share Repurchase Program and Treasury Shares” to the condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for more information about our 2025 Share Repurchase Program.

See Note 4 “Debt” to the condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for more information about the terms of the Amended Credit Agreement, our senior convertible notes, and the 2028 Capped Calls.

We are party to various leasing arrangements, primarily for office, manufacturing and warehouse space that expire at various times through 2040, including any renewal options that we are reasonably certain to exercise. We also have land leases in Penang, Malaysia that expire in 2082 and Athenry, Ireland that expire in 3023 related to our international manufacturing facilities. We anticipate incurring significant expenditures related to the build-out of our manufacturing facilities and investment in equipment. See Note 5 “Leases and Other Commitments—Leases” to the consolidated financial statements in Part II, Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 for more information about our leases. There were no material changes to our lease obligations during the three months ended March 31, 2026.

ITEM 4 - CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Regulations under the Exchange Act require public companies to maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Disclosure controls and procedures include, without limitation, controls and other procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is accumulated and timely communicated to management, including our President and Chief Executive Officer (our principal executive officer) and Chief Financial Officer (our principal financial officer), recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Our management, with the participation of our President and Chief Executive Officer and our Chief Financial Officer, conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on their evaluation as of March 31, 2026, our President and Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective at a reasonable assurance level as of such date.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitation on Effectiveness of Controls

It should be noted that any system of controls, including ours, however well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the system are met. The design of any control system is based, in part, upon the benefits of the control system relative to its costs. Control systems can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. In addition, over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of these and other inherent limitations of control systems, we cannot guarantee that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

PART II. OTHER INFORMATION


ITEM 1 - LEGAL PROCEEDINGS

Securities Class Actions

Between August 21 and October 9, 2024, three substantially similar putative class action complaints were filed against us and certain of our executive officers in the United States District Court for the Southern District of California. On December 13, 2024, the court appointed lead plaintiff and consolidated the three actions (now captioned In re Dexcom, Inc. Class Action Securities Litigation, Lead Case No.: 24-cv-1485-RSH-VET). On January 27, 2025, lead plaintiff filed a consolidated complaint. The consolidated complaint alleges violations of the Exchange Act against us and certain of our current and former executive officers for allegedly making false and misleading statements between April 28, 2023 and July 25, 2024, with respect to our expected revenue for fiscal 2024 and ability to capitalize on our growth potential. On March 13, 2025, we filed a motion to dismiss the consolidated complaint. On May 14, 2025, the court granted the motion to dismiss with leave to amend. On May 28, 2025, lead plaintiff filed an amended consolidated complaint. On June 11, 2025, we filed a motion to dismiss the amended consolidated complaint. On September 9, 2025, the court granted in part and denied in part the motion to dismiss. On October 7, 2025, defendants answered the amended consolidated complaint. On October 10, 2025, defendants filed a motion for judgment on the pleadings as to the two surviving challenged statements. On January 7, 2026, the court granted defendants’ motion for judgment on the pleadings with leave to amend. On February 6, 2026, lead plaintiff filed a second amended consolidated complaint. On February 20, 2026, we filed a motion to dismiss the second amended complaint. On March 20, 2026, we filed a reply in support of the motion. The court has not scheduled any oral argument on the motion.

On October 27, 2025, a putative class action complaint was filed against us and certain of our executive officers in the United States District Court for the Southern District of New York (captioned Prime v. Dexcom, Inc., et al, Case No.: 1:25-cv-08912). The complaint alleges violations of the Exchange Act against us and certain of our executive officers for allegedly making false and misleading statements between July 26, 2024 and September 17, 2025, with respect to the accuracy, reliability, and functionality of our G7 device, as well as our enhancements to and manufacturing of the device. A lead plaintiff has been appointed and filed an amended complaint on April 10, 2026. Our deadline to respond to the amended complaint is June 9, 2026.

Derivative Actions

Between September 13 and April 14, 2025, three putative stockholders filed derivative lawsuits against us and certain of our current and former executive officers and directors in the United States District Court for the Southern District of California. The derivative complaints allege factual allegations largely tracking allegations made in the In re Dexcom, Inc. Securities Class Action Litigation and seek, among other things, damages and restitution to be paid to the Company by the individual defendants, punitive damages, and attorney’s fees and costs. These actions have been consolidated (captioned In Re: Dexcom, Inc. Stockholder Derivative Litigation, Lead Case No.: 24-cv-1645-RSH-VET), and are currently stayed pending a resolution of the motion to dismiss in the In re Dexcom, Inc. Securities Class Action Litigation.

On September 25, 2025, an additional derivative lawsuit was filed against us and certain of our current and former executive officers and directors in the Court of Chancery of the State of Delaware. The allegations largely track those made in the In re Dexcom, Inc. Securities Class Action Litigation and seek, among other things, damages and restitution to be paid to the Company by the individual defendants, punitive damages, and attorney’s fees and costs. This action is currently stayed pending a resolution of the motion to dismiss in the In re Dexcom, Inc. Securities Class Action Litigation.

On March 24, 2026, Dexcom’s board members and certain of its current and former executives were named as defendants in a complaint filed as a stockholder derivative action in the Southern District of California (captioned Bud & Sue Frashier Family Trust U/A Dated 5/5/98 v. Jacob S. Leach, et al., Case No. 3:26-cv-01852-AGS-SBC (S.D. Cal. March 24, 2026). The Company is named as a nominal defendant. The case makes similar allegations to those in the securities class action complaint filed in the Southern District of New York. The parties are negotiating a stay pending the resolution of the securities class action.

G6 and G7 Class Action Litigation

Between September 29, 2025, and January 8, 2026, various plaintiffs, purported users of G6 or G7 devices, filed six overlapping putative class action complaints against us. Four of the complaints originally were filed and are pending in the United States District Court for the Southern District of California (Levens, et al. v. Dexcom, Inc., No. 3:25-cv-02565-BJC-BLM; Estravit v. Dexcom, Inc., No. 3:25-cv-02845-BJC-BLM; Dalora v. Dexcom, Inc., No. 3:25-cv-03210-BJC-BLM; and Dickinson, et al. v. Dexcom, Inc., No. 3:26-cv-00102-BJC-BLM); one of the complaints originally was filed in United States District Court for the Central District of California, and subsequently transferred to the United States District Court for the Southern District of California (Grisoli, et al. v. Dexcom, Inc., No. 3:25-cv-03488-BJC-BLM); and one of the complaints was filed and is pending in the Superior Court of Los Angeles County, California (Chatelain v. Dexcom, Inc., No. 25STCV30722). Plaintiffs in all six actions allege they overpaid for G6 and/or G7 devices or components that were worth less than the purchase price because, among other reasons, G6 and/or G7 devices or components they purchased allegedly were adulterated or misbranded under federal law; G6 and/or G7 devices or components they purchased allegedly failed to perform as advertised; and because we allegedly misled patients and providers about the safety, accuracy, efficacy, and reliability of G6 and/or G7 devices or components. Plaintiffs in each action assert various state law consumer protection, express and implied warranty, common law, and Magnuson-Moss Warranty Act claims, and seek, among other things, damages for economic losses, restitution, disgorgement, injunctive relief, and attorneys’ fees and costs. Plaintiffs seek to represent nationwide classes and state-specific subclasses of individuals.

Federal Court Class Actions

The five cases in the United States District Court for the Southern District of California have been deemed related cases and have been assigned to a single judge. On December 30, 2025, and January 5, 2026, plaintiffs filed motions to consolidate the federal court cases, to appoint interim class counsel, and to establish a briefing schedule on competing motions to appoint interim class counsel. The motions remain pending. The Court has stayed Dexcom’s deadlines to respond to the complaints in all of the federal court actions pending the anticipated filing of a consolidated complaint.

State Court Class Action

The putative class action pending in Los Angeles County Superior Court has been stayed in favor of the federal class actions. The parties must submit a joint status report on the status of the federal class actions no later than August 19, 2026.

We intend to vigorously defend against such claims; however, we cannot be certain of the outcome of our ongoing proceedings and, if determined adversely to us, our business and financial condition may be adversely affected.
