11-K
Audit Report / Information Classification · 95% confidence The document is titled "FORM 11-K" which is an annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934. It is for the fiscal year ended December 31, 2025. The text contains audited financial statements, including statements of net assets and changes in net assets available for benefits, plus notes to the financial statements. It also includes the report of the independent registered public accounting firm (auditor's opinion) on the Plan's financial statements. The document is comprehensive, includes substantive financial data and the auditor's opinion, which confirms it is not just an announcement but the full report itself. "FORM 11-K" is the annual report for employee benefit plans, akin to an Annual Report but distinct from a 10-K which is for general corporate filings. Given the content and form designation, this filing best matches an Audit Report / Information (AR) because it is a standalone audited report of the 401(k) savings plan's financial statements, rather than a broader corporate annual report (10-K) or other category. Therefore, the correct classification is AR with high confidence. FY 2025

11-K
Annual Report Classification · 95% confidence The document is a Form 11-K filed with the U.S. Securities and Exchange Commission, which is an annual report for employee benefit plans. It includes audited financial statements, notes to financial statements, and a report of an independent registered public accounting firm. The content is specific to The ATI Retirement Plan, detailing financial positions as of December 31, 2025 and 2024, contributions, investments, and plan descriptions. It contains comprehensive financial data and analysis related to the plan, consistent with an official annual report rather than an announcement or certification. Therefore, the correct classification is annual report related to employee benefit plan filings, which aligns with the Annual Report category (10-K) in the context of specific SEC employee benefit plan filings like Form 11-K.
