Gibraltar Industries’ plan to acquire OmniMax International for $1.335 billion marks one of the sector’s largest recent moves toward supplier consolidation, with direct implications for distributors in the roofing accessories and rainware markets. The deal significantly expands Gibraltar’s residential building-products platform and creates a manufacturer with broader reach, a larger brand portfolio, and greater pricing and procurement influence across distribution channels.
OmniMax — whose brands include Amerimax, Berger, Flamco, Verde, Millennium Metals, Nu-Ray Metals, and Hancock Enterprises — is expected to generate $565 million in adjusted net sales in 2025. Gibraltar said the acquisition will be immediately margin-accretive, supported by $35 million in expected cost synergies by 2028 and approximately $100 million in cash-tax benefits. Once closed, more than 80% of Gibraltar’s revenue and adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) will come from its residential segment.
The combination brings together two suppliers with deep ties to home-improvement retailers and building-product distributors. For distributors, the deal indicates a more concentrated supplier base in a category where availability, fill rates, and SKU breadth directly influence jobsite performance and contractor loyalty. A larger, integrated Gibraltar-OmniMax platform could streamline vendor management and create more unified national programs, but it may also narrow sourcing alternatives in regions where both companies already hold significant share.
Gibraltar highlighted the opportunity to merge operating systems, manufacturing processes, and localized service footprints — changes that could improve supply-chain consistency for distributors, particularly during peak roofing and repair seasons. The company’s integration plan centers on aligning production networks, leveraging logistics efficiencies, and extending business-process discipline across the combined enterprise. If successful, distributors could see steadier lead times and fewer stockouts in categories that are prone to seasonal and weather-driven volatility.
At the same time, Gibraltar’s larger scale and projected efficiency gains could influence channel pricing and margin structures. The company expects stronger cash flow and a clear path to deleveraging — from an estimated 3.7 times adjusted EBITDA at closing to 2.0 to 2.5 times within two years — providing resources to invest in product expansion, customer programs, and footprint growth.
Gibraltar secured committed financing from Bank of America, Wells Fargo, and KeyBanc Capital Markets to support the transaction, which is expected to close in the first half of 2026 pending regulatory approval. The acquisition has been unanimously approved by Gibraltar’s board and does not require a shareholder vote.
For distributors, the Gibraltar-OmniMax deal underscores an accelerating trend: scale is reshaping the building-products supplier landscape, and manufacturers with broader portfolios and tighter operational control are positioning themselves as more dominant partners in an increasingly competitive channel.
