Basis of Presentation and Principles of Consolidation

The Company’s Condensed Consolidated Financial Statements (unaudited) and related disclosures as of September 30, 2026 and for the three and nine months ended September 30, 2026 and 2025 are unaudited. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. These financial statements follow the same accounting policies and methods of their application as the Company’s most recent annual consolidated financial statements. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. In the Company’s opinion, these financial statements include all normal and recurring adjustments necessary for the fair statement of the results for the interim period. The results of operations for the three and nine months ended September 30, 2026 are not necessarily indicative of the results to be expected for the full year, due to the seasonality of our business.

The Company prepares its financial statements in accordance with the rules and regulations of the SEC. The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

Recent Accounting Pronouncements

Recently Issued Accounting Pronouncements

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which improves and clarifies the guidance regarding when disclosures should be provided in interim reporting periods. This standard is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The amendments can be applied either prospectively or retrospectively to any or all prior periods presented in the financial statements. The Company plans to adopt this ASU on its effective date and anticipates no material impact to the interim disclosures.

In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities, which establishes authoritative guidance on the accounting for government grants, including grants related to an asset and grants related to income. This standard specifies the timing of recognition, the two available approaches to record the grant (the deferred income and the cost accumulation approach) and requires disclosure consistent with current disclosure requirements. The standard is effective for annual reporting periods beginning after December 15, 2028, and interim reporting periods within those annual reporting periods, with early adoption permitted. The Company plans to adopt this ASU on its effective date and is currently evaluating the impacts this amendment will have on its consolidated financial statements and required disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40). This pronouncement requires disaggregated disclosure of income statement expenses for public business entities. In January 2025, the FASB issued ASU 2025-01, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date, which clarified the effective date of this standard. This standard requires disclosure in tabular format of disaggregation of relevant expense captions presented on the income statement by certain natural expense categories with certain related qualitative disclosures within the notes to the financial statements. The ASU does not change the expense captions an entity presents on the income statement. The standard is effective for fiscal years beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. The Company plans to adopt this ASU on its effective date on a retrospective basis for all prior periods presented in the financial statements.
