Griffon Corporation is a global enterprise with a market capitalization of $4.9 billion, positioning itself as a significant player in the construction materials and home & building products sector. Trading at $106.30 as of August 6, 2026, the stock has appreciated 50% over the preceding twelve months, indicating robust investor confidence in the company's strategic execution and market positioning.

Often, executives who sell into a surging stock are trimming a modest holding, but Mehmel is working from a deep one, keeping roughly 753,000 shares, worth about $80 million, even after this sale. That scale is the context that matters because parting with 37,000 shares as the price spiked on earnings looks like a long-tenured operator taking a little off a large position, not stepping away from it. The earnings that lifted the stock, meanwhile, were solid. Griffon grew fiscal third-quarter revenue 7% to $481 million and reaffirmed full-year guidance of $1.8 billion in revenue and $458 million in adjusted EBITDA. Alongside the results, management set a new leverage target of 1.5 to 2.5 times net debt to EBITDA, the firm said on its earnings call a signal it sees its balance sheet in better shape after years of heavier borrowing. And that debt load is still the thing to watch: Griffon carries well over a billion in long-term debt, and the new target only matters if softer demand doesn't undercut the cash flow paying it down
