8-K - KAISER ALUMINUM CORP (0000811596) (Filer)
Earnings Release Classification · 95% confidence The document is a Form 8-K filed with the SEC, dated April 22, 2026, reporting preliminary, unaudited financial results for the quarter ended March 31, 2026. It specifically states that the press release with the financial results is furnished as an exhibit and incorporated by reference. The document is short (3,715 characters) and primarily serves as a current report to announce the earnings release rather than containing the full financial statements or detailed analysis itself. According to the rules, such a document is classified as an Earnings Release (ER) because it announces quarterly financial results highlights. The presence of a press release with preliminary results aligns with the ER category rather than a full Interim/Quarterly Report (IR) or Annual Report (10-K).
