| Revision of prior period financial statements |
Note 23. Revision of prior period financial statements As discussed in Note 1 (Organization and basis of presentation), a summary of the revisions to the Company’s previously reported financial statements is presented below. In evaluating whether its previously issued consolidated financial statements were materially misstated, the Company applied the guidance in Accounting Standard Codification (ASC) Topic 250, Accounting Changes and Error Corrections, including ASC Topic 250-10-S99-1 (SAB Topic 1.M), Assessing Materiality, and ASC Topic 250-10-S99-2 (SAB Topic 1.N), Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements. The Company evaluated the materiality of the extended warranty misstatement and the Other Misstatements, in consideration of both quantitative and qualitative factors, and determined that they were not material, individually or in the aggregate, to any previously issued consolidated financial statements. However, correcting these misstatements in the current period would have been material to the consolidated financial statements for the three and six months ended June 30, 2026, and would be material to the Company’s forecasted consolidated results of operations for the year ending December 31, 2026. Accordingly, the Company has revised the applicable prior period financial statements presented herein and will reflect these revisions in future filings that include the affected periods.
