Principles of Consolidation and Basis of Presentation

The condensed consolidated financial statements include the accounts of Tempus AI, Inc. and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated financial statements and accompanying notes were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial information and include the assets, liabilities, revenue and expenses of all wholly owned subsidiaries. Investments in unconsolidated entities in which the Company does not have a controlling financial interest, but has the ability to exercise significant influence, are accounted for under the equity method of accounting. Investments in unconsolidated entities in which the Company is not able to exercise significant influence are accounted for under the cost method of accounting. Certain information and disclosures

normally included in the annual consolidated financial statements prepared in accordance with GAAP have been omitted. Accordingly, the unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Form 10-K for the year ended December 31, 2025. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and reflect, in management’s opinion, all the adjustments of a normal, recurring nature that are necessary for the fair statement of the Company’s financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the results expected for the full year or any other period.

In the opinion of the Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of its financial position as of March 31, 2026 and its results of operations for the three months ended March 31, 2026 and 2025, and cash flows for the three months ended March 31, 2026 and 2025. The condensed consolidated balance sheet at December 31, 2025, was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements.

The Company believes that its existing cash and cash equivalents and marketable equity securities at March 31, 2026 will be sufficient to allow the Company to fund its current operating plan through at least a period of one year from the date of issuance of this Quarterly Report on Form 10-Q. As the Company continues to incur losses, its transition to profitability is dependent upon a level of revenues adequate to support the Company’s cost structure. Future capital requirements will depend on many factors, including the timing and extent of spending on research and development activities and growth related expenditures.

Other than described below, there have been no changes to the Company’s significant accounting policies described in the “Notes to the Consolidated Financial Statements” included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 that have had a material impact on the Company’s consolidated financial statements and accompanying notes.

Use of Estimates

Use of Estimates

The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and classifications of assets and liabilities, revenue and expenses, and the related disclosures of contingent assets and liabilities in the condensed consolidated financial statements and accompanying notes. The most significant estimates are related to revenue, accounts receivable, stock-based compensation, operating lease liabilities, the useful lives of property, equipment, capitalized software and intangible assets, and the cash flows used in determining the fair value of acquired intangible assets. Actual results could differ from those estimates.

Capitalized Software

Capitalized Software

In accordance with ASC 350-40, Internal-Use Software, the Company capitalizes eligible software development costs for the Company's internally developed projects that are not intended for sale or externally marketed. Internal-use software costs are recorded at cost less accumulated amortization in Capitalized software on the condensed consolidated balance sheets. The Company adopted ASU 2025-06 on January 1, 2026 using a prospective transition basis. Under ASU 2025-06, development costs for applicable projects will begin capitalization when management commits to funding a software project and it is probable that the project will be completed and the software will be used to perform the function intended. The Company capitalizes costs directly attributable to the development, design and implementation of the internal use software. Any costs incurred during subsequent efforts to upgrade and enhance the functionality of the software are also capitalized. Capitalized software costs are amortized on a straight-line basis when the capitalized software is ready for its intended use over the estimated useful life of the software, which is typically three to five years.

Recently Adopted Accounting Standards / Recently Issued Accounting Pronouncements Not Yet Adopted

Recently Adopted Accounting Standards

In November 2024, the FASB issued ASU 2024-04, “Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments”, which clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as induced conversions. The Company adopted the standard on January 1, 2026 on a prospective basis. The adoption of this standard did not have a material impact on the Company's financial statements.

In July 2025, the FASB issued ASU No. 2025-05, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets". ASU 2025-05 provides a practical expedient that in developing reasonable and supportable forecasts as part of estimating expected credit losses, all entities may assume that current conditions as of the balance sheet date do not change for the remaining life of the asset. The Company adopted the standard on January 1, 2026 on a prospective basis. The Company elected the practical expedient provided by the standard which allows the Company to assume that current macroeconomic conditions as of the balance sheet date persist for the remaining contractual life of current accounts receivable. The adoption of this standard did not have a material impact on the Company's financial statements.

In September 2025, the FASB issued ASU 2025-06, “Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software.” ASU-2025-06 revises the recognition guidance for internal-use software by eliminating the previous model based on software development stages and introducing a principles-based approach. Under the new guidance, capitalization begins when management has authorized and committed to funding the project, and it is probable that the software will be completed and used for its intended purpose. The Company early adopted the standard on January 1, 2026 using a prospective transition approach. The adoption of this standard did not have a material impact on the Company's financial statements. Refer to Note 6 for additional information over the Company's capitalized software.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income (Topic 220): Disaggregation of Income Statement Expenses.” ASU 2024-03 requires additional disclosures aimed at enhancing the transparency and decision usefulness of income statement expenses. This ASU is effective for fiscal years beginning after December 15, 2026 as well as interim periods beginning after December 15, 2027 and may be applied either prospectively to financial statements issued for reporting periods after the effective date of this ASU or retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact of the guidance on the related disclosures.

In September 2025, the FASB issued ASU No. 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606), which amends the existing guidance to (a) reduce the cost and complexity of evaluating whether contracts with features based on the operations or activities of one of the parties to the contract are derivatives, (b) better portray the economics of those contracts in the financial statements, and (c) reduce diversity in practice resulting from the broad application of the current guidance and changing business environment. The amendments also are expected to reduce diversity in practice by clarifying the applicability of Topic 606, Revenue from Contracts with Customers, to share-based noncash consideration from a customer for the transfer of goods or services. This ASU is effective for fiscal years beginning after December 15, 2026. The Company is currently evaluating the impact of the guidance on the related disclosures.

In December 2025, the FASB issued ASU 2025-11, “Interim Reporting (Topic 270): Narrow-Scope Improvements.” ASU 2025-11 clarifies interim disclosure requirements and the applicability of Topic 270. The update provides clarity about current interim requirements. The amendments in this update also include a disclosure principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The amendments in this ASU are required to be adopted for interim periods within annual reporting periods beginning after December 15, 2027 and can be adopted using either a prospective or retrospective method. Early adoption is permitted. The Company is currently evaluating the impact of the guidance on the related disclosures.

In December 2025, the FASB issued ASU 2025-12, Codification Improvements. This ASU represents changes to the ASC that clarify, correct errors in or make other improvements to a variety of topics that are intended to make it easier to understand and apply, including amendments to clarify the calculation of earnings per share when a loss from continuing operations exists. This ASU is effective for fiscal years beginning after December 15, 2026 and interim periods within those fiscal years, with early adoption permitted. Entities are required to apply the amendments to ASC 260 retrospectively. All other amendments may be applied prospectively or retrospectively. The Company is currently evaluating the impact of the guidance on the related disclosures.
