Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

These interim unaudited condensed consolidated financial statements have been prepared in accordance with GAAP as established by the FASB for interim financial information and with the instructions to Form 10-Q and should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. The results of operations for interim periods are not necessarily indicative of the results of operations for the full year.

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, and reported amounts of revenues and expenses. On an ongoing basis, management evaluates its estimates based upon historical experience, observance of trends, information available from outside sources, and various other assumptions that management believes to be reasonable under the circumstances. Actual results may differ from these estimates under different conditions or assumptions.

In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of financial position, results of operations, and cash flows at the dates and for the periods presented have been included.

Recent Accounting Pronouncements - Adopted and Issued, not yet Adopted

Recent Accounting Pronouncements – Adopted

In July 2025, the FASB issued Accounting Standards Update ("ASU") 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. This ASU provides optional relief by providing entities with a practical expedient and private companies an accounting policy election when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under Topic 606. For public entities, the update is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2025. The Company adopted the update for the condensed consolidated financial statements issued for the three months ended March 31, 2026. As of March 31, 2026, the Company did not elect the practical expedient

and the update's policy election for private companies is not applicable to the Company. Adoption of ASU 2025-05 does not have a material impact on the Company’s condensed consolidated financial statements.

There were no other applicable material accounting pronouncements that have been adopted during the three month period ended March 31, 2026.

Recent Accounting Pronouncements – Issued, not yet Adopted

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 eliminates the traditional stages for internal use software (preliminary, development, post-implementation) used to determine when to capitalize costs. Instead, capitalization begins when both management has authorized and committed funding for the project and it is probable the project will be completed and the software will be used as intended. The amendments will be effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The Company expects to adopt the update for the annual financial statements issued for the year ending December 31, 2027, and is currently reviewing the impact that the adoption of ASU 2025-06 may have on the consolidated financial statement disclosures.

On March 6, 2024, the SEC adopted new Climate Disclosure Rules, which would have required companies to publish information that describes the climate-related risks that are reasonably likely to have a material impact on a company’s business or consolidated financial statements. The final rules would have required companies to disclose material climate-related risks, activities to mitigate or adapt to such risks, information about the companies’ board of directors’ oversight of climate-related risks and management’s role in managing climate-related risks, and information on any climate-related targets or goals that are material to the companies’ business, results of operations or financial condition. On March 15, 2024, the U.S. Court of Appeals for the Fifth Circuit granted an administrative stay of the SEC’s final Climate Disclosure Rules, in response to legal challenges unaffiliated with the Company. On March 27, 2025, the SEC voted to end its defense of its Climate Disclosure Rules. On April 24, 2025, the U.S. Court of Appeals for the Eighth Circuit (the “Court”) granted an order to hold in abeyance the cases regarding the validity of the SEC's final Climate Disclosure Rules. On September 12, 2025, the Court issued an order continuing the abeyance until the SEC reconsiders the Climate Disclosure Rules via notice-and-comment or renews its defense of the Climate Disclosure Rules. The Company will continue to monitor updates to the Climate Disclosure Rules and potential impacts on the consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This ASU requires disaggregated disclosure of certain income statement expenses for public entities. For public entities, the update is effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. The Company expects to adopt the update for the annual financial statements issued for the year ending December 31, 2027, and is currently reviewing the impact that the adoption of ASU 2024-03 may have on the consolidated financial statement disclosures.

There were no other recent applicable material accounting pronouncements that have been issued, but not yet adopted as of March 31, 2026.
