Karman Holdings shares were lower in Tuesday trading as investors focused on the company’s annual-report timing after Karman filed a Form 12b-25 late-notice for its Form 10-K for the year ended December 31, 2025. The notice cited the need for additional time to complete procedures related to preparing and auditing its consolidated financial statements, and it said meeting the original deadline would have required unreasonable effort or expense.

In the late-filing notice, Karman indicated it expected to file the 10-K within the standard 15-day extension period permitted under SEC rules. The company also said it did not anticipate any material changes to the financial information previously furnished in its Form 8-K and did not expect significant changes in results of operations versus the prior year.

Even when a company frames a delay as procedural, late filings often pressure shares because they can raise uncertainty around internal reporting processes, audit completion, and the timing of future disclosures. The move comes after Karman’s 10-K was ultimately signed April 2, 2026 and filed shortly thereafter, highlighting that investors remain sensitive to any perceived slippage in reporting cadence.
