Smart Money Convergence

GFF does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

Griffon Corp (GFF) filed this 8-K solely to recast financials from its fiscal-year 2025 10-K, retroactively classifying sold or wound-down operations as discontinued operations for fiscal 2025, 2024, and 2023. The actions driving this include the completed joint venture involving AMES North America and ONCAP-affiliated businesses (closed June 9, 2026), the sale of AMES Australasia into a management-led JV (closed July 31, 2026), and the cessation of AMES U.K. operations as of March 31, 2026. The company also now operates as one reportable segment. The recast appears in Exhibit 99.1, but the 8-K is not an amendment or restatement of the original 10-K, and the filing excerpt doesn't include any proceeds or financial numbers.

Griffon (GFF) closed the sale of its AMES Australasia business on July 31, 2026, to a joint venture put together by that business's management with backing from Australian financial investors. The deal follows the Share Sale Agreement signed in June; at closing, the JV's parent company, TopCo, issued a PIK note to a Griffon subsidiary, and Griffon also signed a side letter covering transfer of the equity and note to other Griffon units, advancement of certain financing costs to be reimbursed by the JV, and a delayed independent director appointment. The 8-K excerpt doesn't give the PIK note's full terms or the sale price.
