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 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.

We have prepared the accompanying unaudited 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.

These 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, 2023 included in the Annual Report on Form 10-K that we filed with the SEC on February 8, 2024.

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 loss in the equity section of our 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 (expense), net in our consolidated statements of operations.

The preparation of consolidated financial statements in conformity with GAAP requires us to make certain estimates and assumptions that affect the amounts reported in our consolidated financial statements and the disclosures made in the accompanying notes. Areas requiring significant estimates include rebates, excess or obsolete inventories and the valuation of inventory, accruals for litigation contingencies, and the amount of our worldwide tax provision and the realizability of deferred tax assets. Despite our intention to establish accurate estimates and use reasonable assumptions, actual results may differ from our estimates.

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.

Contract balances represent amounts presented in our 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.

Our performance obligations are generally satisfied within twelve months of the initial contract date. The deferred revenue balances related to performance obligations that will be satisfied after twelve months were $7.4 million as of March 31, 2024 and December 31, 2023. These balances are included in other long-term liabilities in our consolidated balance sheets. Revenue recognized in the period from performance obligations satisfied in previous periods was not material for the periods presented.

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, warrants, our senior convertible notes, and collaborative sales-based milestones. Potentially dilutive common shares issuable upon vesting of RSUs, PSUs, and exercise of warrants 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. In periods of net losses, we exclude all potentially dilutive common shares from the computation of the diluted net loss per share for those periods as the effect would be anti-dilutive.

In November 2023, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly reviewed by the chief operating decision maker, or CODM, and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The ASU also allows, in addition to the measure that is most consistent with U.S. GAAP, the disclosure of additional measures of segment profit or loss that are used by the CODM in assessing segment performance and deciding how to allocate resources. All disclosure requirements under ASU 2023-07 are also required for public entities with a single reportable segment. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, on a retrospective basis, with early adoption permitted. We are currently evaluating the impact of this standard on our disclosures.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures. The ASU requires greater disaggregation of information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The ASU applies to all entities subject to income taxes and is intended to help investors better understand an entity’s exposure to potential changes in jurisdictional tax legislation and assess income tax information that affects cash flow forecasts and capital allocation decisions. The ASU is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The ASU should be applied on a prospective basis although retrospective application is permitted. We are currently evaluating the impact of this standard on our disclosures.

On March 6, 2024, the SEC adopted SEC Release Nos. 33-11275; 34-99678, The Enhancement and Standardization of Climate-Related Disclosures for Investor, to require the disclosure of certain climate-related information in registration statements and annual reports, including Scope 1 and 2 emissions and information about climate-related risks that have materially impacted, or are reasonably likely to have a material impact on, a company’s business strategy, results of operations, or financial condition. In addition, under the final rules, certain disclosures related to severe weather events and other natural conditions will be required in audited financial statements. The disclosure requirements will begin phasing in for our reports and registration statements including financial information in the fiscal year ending December 31, 2025. On April 4, 2024, the SEC issued an order staying the final rules until the completion of judicial review. We are currently evaluating the impact of this final rule on our disclosures.
