Gibraltar Industries agreed on November 16, 2025 to acquire OmniMax International, a residential roofing accessories and rainwater products maker, from Arundel Square Garden LLC for $1.335 billion in cash, subject to customary adjustments. The company expects the deal to close in the first half of 2026 and says it will not need a shareholder vote, but it will rely on about $1.8 billion of committed bank financing and expects post-deal leverage of 3.7x 2025 adjusted EBITDA including synergies.
Key points
