Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation |
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 and nine months ended September 30, 2025 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2025. 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, 2024 included in the Annual Report on Form 10-K that we filed with the SEC on February 18, 2025. 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 (loss) 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.

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.

Use of Estimates |
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, excess and obsolete inventories, 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.
Concentration of Credit Risk |
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
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. Accounts receivable as of September 30, 2025 and December 31, 2024 included unbilled accounts receivable of $16.6 million and $15.2 million, respectively. 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. The deferred revenue balances related to performance obligations that will be satisfied after twelve months were $8.5 million as of September 30, 2025 and $9.5 million as of December 31, 2024. These balances are included in other long-term liabilities in our condensed consolidated balance sheets.
Net Income Per Share |
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, 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.
Recent Accounting Guidance |
Recent Accounting Guidance
Recently Issued Accounting Pronouncements Not Yet Adopted In December 2023, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or 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. We will adopt the standard on December 31, 2025. 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 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 are currently evaluating the impact of this standard on our condensed consolidated financial statements.
