Griffon Corporation (NYSE:GFF) (the "Company" or "Griffon") today announced it has entered into a definitive agreement to sell its AMES Australasia business to a joint venture it is forming with an investment group led by the management of AMES Australasia with support from Australian financial investors.

Under the terms of the agreement, Griffon will receive $185 million at closing and $50 million in a subordinated note in the joint venture. Griffon will hold a 49% equity interest in the joint venture post-closing. The remaining 51% ownership of the joint venture will be held by an investment group led and controlled by Simon Hupfeld, who upon closing will become the Executive Chairman of the business.

"This joint venture will best position AMES Australasia to serve its valued customers while generating both immediate and longer-term value for Griffon shareholders," said Ronald J. Kramer, Chairman and CEO of Griffon. "We have confidence this management team, which has grown the business from a modest provider of wheelbarrows to a category leader in home and lifestyle products for consumers and professionals, will continue its long track record of exceptional performance."

"We are thrilled to embark on this next chapter for our business and the people behind it," said Mr. Hupfeld. "This joint venture gives us the platform to accelerate the growth of the business while continuing to benefit from our strong partnership with Griffon. We are deeply committed to our customers, our people, our suppliers and the communities we serve, and we look forward to building on the strong foundation we have established together."

The joint venture will be financed through committed debt financing, equity from the joint venture partners, and the Griffon subordinated note. This transaction is subject to customary closing conditions and is expected to be completed by Griffon's fiscal year ending in September 2026.

Goldman Sachs & Co. LLC acted as financial advisor to Griffon and provided committed debt financing for the joint venture. Houlihan Lokey Capital, Inc. acted as financial advisor to Griffon's Board. Clayton Utz acted as legal counsel to Griffon. Ashurst Australia acted as legal counsel to the investment group led by the management of AMES Australasia.
