Installed Building Products Buys Old Dominion Group for $698 Million

Installed Building Products has agreed to acquire Old Dominion Group at an enterprise value of $698 million, net of $27 million in transaction bonuses, in a cash-and-stock deal that pushes the installer's commercial revenue share from roughly 20% to 28%.

The buyer funded the consideration with approximately 60% cash and 40% newly issued IBP shares handed to Old Dominion shareholders. That structure matters: equity consideration dilutes existing owners but preserves balance-sheet capacity — a point CFO Michael Miller was quick to stress. "The transaction has been structured to preserve meaningful financial flexibility, and we expect continued strong cash flow generation to support the reduction of acquisition-related leverage over time," Miller said.

What does Old Dominion bring to the deal?

Old Dominion generated approximately $370 million in revenue and $68 million in adjusted EBITDA in the twelve months ended September 30, 2026. On those figures, IBP is paying roughly 10.3 times trailing adjusted EBITDA for the target — before crediting any of the promised synergies.

Old Dominion folds into IBP's existing $50 million commercial mechanical insulation business to create a platform of roughly $420 million in combined revenue. The target serves healthcare, education, manufacturing, industrial facilities and data centers — end markets IBP describes as mission-critical and higher-growth than its core residential base.

CEO Jeff Edwards framed the deal as a strategic broadening rather than a bolt-on. "The acquisition of ODG represents a significant step forward in our strategy to expand our presence in commercial and complementary building products," Edwards said. He added that the combination "supports meaningful opportunities to deepen customer and vendor relationships, expand our geographic reach and serve a broader range of high-growth commercial and industrial projects." What the statement does not say is how much revenue overlap, if any, the two businesses share — the geographic and customer detail beyond end markets is thin.

How much cost savings are on the table?

IBP expects $6 million to $8 million in annualized cost savings within 24 months, principally from procurement and administrative efficiencies. Set against Old Dominion's $68 million adjusted EBITDA, that is a modest 9% to 12% uplift — a conservative synergy target by acquisition standards.

The company also expects the transaction to be immediately accretive to revenue growth, adjusted operating margins and adjusted earnings per share. Miller repeated the claim in his own words: "We expect the acquisition of ODG to be immediately accretive to our revenue, adjusted margins, and adjusted earnings per share, further strengthening IBP's financial profile and long-term earnings potential." Immediate accretion claims are standard deal language; the margin math will only be testable when IBP reports its first combined quarters.

Who runs the business now?

Old Dominion keeps its regional brands and existing operating leadership under CEO Jeff Davoud. Approximately 75 leaders and managers will receive equity ownership opportunities aligned with the combined company — an unusual retention mechanism at that scale for a deal of this size.

Jeff Davoud defended the arrangement in personal terms. "Broadening ownership is a way to recognize those contributions and strengthen what we've built together for the future," he said, adding that the shared incentives are "tied directly to multi-year growth and operational execution." His framing echoes a sale rationale as much as a growth plan.

Founder Roddy Davoud, who started the company 45 years ago, endorsed the buyer. "I am pleased that ODG is joining a company, in IBP, that cares both for their employees and their operational excellence," he said.

What about the $180 million incentive pool?

Separately, IBP approved performance-based inducement awards for up to 50 incoming non-executive employees. The awards carry an aggregate target grant-date value of $180 million and a maximum potential issuance of 2.5 million shares. Payout depends on financial and operational milestones measured over three- and five-year periods, plus continued service — meaning the full cost only lands if the combined business performs.

Goldman Sachs and BofA Securities advised IBP financially, with Calfee, Halter & Griswold as legal counsel. William Blair advised Old Dominion, and Williams Mullen served as its legal counsel. The deal's real test begins at the first post-close earnings report, when IBP must show the accretion it has already promised.
