Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies and Estimates	Basis of presentation and summary of significant accounting policies and estimates Basis of presentation The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"), including those for interim financial information, and with the instructions for Quarterly Reports on Form 10-Q and Article 10 of Regulation S-X issued by the U.S. Securities and Exchange Commission (the "SEC"). In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation of the Company's financial position, results of operations and cash flows for the periods presented. The results of operations for such periods are not necessarily indicative of the results that may be expected for any future period. The accompanying financial statements should be read in conjunction with the audited financial statements and the related notes thereto for the year ended December 31, 2025 included in the Company's Annual Report on Form 10-K filed with the SEC on March 6, 2026. Certain information and disclosures normally included in the annual financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, have been condensed or omitted. Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification ("ASC") and Accounting Standards Update ("ASU") issued by the Financial Accounting Standards Board ("FASB"). Basis of consolidation These condensed consolidated financial statements include the financial statements of Xeris and its subsidiaries. All intercompany transactions have been eliminated. Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses included in the financial statements and accompanying notes. Actual results could differ from those estimates. Revenue recognition The Company applies the guidance in ASC Topic 606, Revenue from Contracts with Customers, to all contracts with customers within the scope of the standard. The Company sells product primarily to wholesalers or a specialty pharmacy that subsequently resell to retail pharmacies or patients. The Company enters into arrangements with payors, group purchasing organizations, and healthcare providers that provide for government-mandated or privately-negotiated rebates, chargebacks and discounts related to the Company's products. The Company currently sells Recorlev, Gvoke, and Keveyis in the United States only. Revenue is recognized when the Company's customer (e.g., a wholesaler or specialty pharmacy) obtains control of promised goods or services, which is when the Company's obligations under the terms of the contract with the customer are satisfied, based on the consideration the Company expects to receive in exchange for those goods or services. Revenues are recorded at the net product sales price, which includes estimated allowances for patient copay assistance programs, prompt payment discounts, payor rebates, chargebacks, service fees, and product returns, all of which are recorded at the time of sale to the pharmaceutical wholesaler or other customer. The Company applies significant judgments and estimates in determining some of these allowances. If actual results differ from its estimates, adjustments are made to these allowances in the period in which the actual results or updates to estimates become known. Such revenue is reported as product revenue, net in the condensed consolidated statements of operations and comprehensive loss. Additionally, the Company earns revenue from research collaborations for the use of Xeris' proprietary formulation technology platforms and royalties from branded products. Such revenue is recognized as earned in accordance with contract terms when it can be reasonably estimated and collectability is reasonably assured. This revenue is reported as royalty, contract and other revenue in the condensed consolidated statements of operations and comprehensive loss. The aggregate amount of the transaction price allocated to research collaboration performance obligations that are unsatisfied as of the end of the reporting period is $5.0 million. Concentration of credit risk For the three and six months ended June 30, 2026, four customers accounted for 99% and 98% of the Company's gross product revenue, respectively. For the three and six months ended June 30, 2025, four customers accounted for 96% of the Company's gross product revenue. At June 30, 2026 and December 31, 2025, the same four customers accounted for 97% and 92% of the trade accounts receivable, net, respectively. New accounting pronouncements Adopted accounting standards In November 2024, the FASB issued ASU 2024-04, Debt - Debt with Conversion and Other Options (Subtopic 470-20) - Induced Conversions of Convertible Debt Instruments. The FASB issued final guidance to clarify the requirements for determining whether to account for certain early settlements of convertible debt instruments as induced conversions. The guidance, which is based on a consensus-for-exposure of the Emerging Issues Task Force (EITF), is intended to address issues that stakeholders encountered when applying the guidance on induced conversions in Accounting Standards Codification (ASC or Codification) 470-20, Debt — Debt with Conversion and Other Options, to certain settlements of cash convertible debt instruments. For all entities, the guidance is effective for fiscal years beginning after December 15, 2025, and interim reporting periods within those fiscal years. Early adoption is permitted for all entities that have adopted ASU 2020-06, which simplified an issuer’s accounting for certain financial instruments with characteristics of liabilities and equity. The Company adopted this standard in the first quarter of 2026 and it did not have an immediate impact on the Company's Financial Statements and related disclosures. Pending accounting standards In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40), which requires disaggregated disclosure of income statement expenses for public business entities (PBEs). The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. ASU 2024-03 is effective for all PBEs for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The Company is evaluating the timing and effects of the adoption of this standard on the Company's disclosures. In January 2025, the FASB issued ASU 2025-01, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Topic 220). This standard clarifies the effective date of ASU 2024-03 to annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. The Company is evaluating the timing and effects of the adoption of this standard on the Company's disclosures.
