Installed Building Products, Inc.

▲ Bull Case

• ◆ROIC durability is structurally underappreciated. IBP held 30%+ ROIC through the 2023 housing slowdown when starts fell 15% from peak. The combination of asset-light branches, scale purchasing discount on insulation, IECC 2021 per-home revenue uplift, and disciplined acquisitions at 4–7x EBITDA produces ~22% returns on incremental capital deployed — a compounding flywheel that survives every modern cycle.
• ◆Non-cyclical M&A engine adds $170–230M of revenue per year regardless of housing. IBP has averaged 10–13 deals/year for 5+ consecutive years through COVID, the 2022 rate shock, and the 2023 slowdown. With BLD removed from public-installer competition for sellers, IBP's relative position in the seller market strengthens, not weakens.
• ◆Multiple gap to strategic-buyer comp is now wide enough to matter. QXO paid 14x EBITDA for BLD; IBP trades at ~9.4x. Even at a justifiable strategic-control premium of 12x (still below BLD takeout), IBP would be worth ~$280/share. A strategic-interest disclosure event would re-rate the stock independent of organic fundamentals.

▼ Bear Case

• ◆Higher for longer suppresses housing starts through FY27 — if mortgage rates remain at 6.5%+ and SF starts stagnate at 900–950K, IBP's organic same-branch growth runs flat-to-negative for 2 more years, and the multiple compresses back to ~14x P/E on a housing cyclical narrative reset (Step_15 bear case → $151).
• ◆National homebuilder pricing power reasserts in a weaker market. D.R. Horton and Lennar account for an outsized share of IBP's volume; in a soft demand environment, they have proven willing to push back on installer pricing, potentially reversing 2021–2022 IECC-driven per-home revenue gains and compressing IBP gross margins from 32.7% toward 31%.
• ◆Acquisition multiple inflation from PE roll-up competition — if 5–6x EBITDA acquisitions creep to 8–9x as private equity competes harder for fragmented services, IBP's Stream B value compounder compresses from 22% incremental ROIC to ~15–17%, materially shrinking the M&A contribution to per-share intrinsic value.

“The Street is divided on whether IBP is a high-quality compounder priced as a cyclical (our variant view) or a housing cyclical correctly priced for the current rate environment (consensus view). Bulls argue ROIC of 30%+ has been demonstrated through cycle and deserves quality-compounder multiple of 19–22x; Bears argue 2026 organic growth deceleration proves IBP can't escape housing and deserves cyclical multiple of 13–16x. The QXO–BLD deal at 14x EBITDA partially settles this debate in the bulls' favor, validating that the cyclical multiple compression has gone too far. But Street tends to discount take-out scenarios in standalone valuation. Sub-debate: Whether IBP's commercial/heavy-commercial pivot is meaningful enough to materially de-cyclical the business.”

• ◆Mortgage rate decline to 5.5–6.0% unlocking pent-up housing demand and accelerating SF starts to 1.1M+
• ◆QXO–BLD close in Q3 2026 removes IBP's primary public peer, structurally elevating IBP's strategic value and sparking strategic-interest speculation
• ◆IECC 2021 adoption by remaining ~20 states adds $800–2,000 per-home insulation revenue in covered geographies
• ◆Commercial / heavy-commercial growth offsetting residential weakness, providing a new organic growth lever
• ◆Counter-cyclical acquisition acceleration if soft housing market produces willing sellers at 4–5x EBITDA
• ◆Spray-foam mix shift continues lifting per-home revenue and gross margin

• ◆Mortgage rates stay at 7%+ through FY27 suppressing SF starts to 900–950K — primary base-case risk
• ◆Homebuilder pricing power assertion in soft demand environment — compresses gross margin 100–200bps
• ◆CEO succession — Jeff Edwards is irreplaceable; departure without credible successor triggers meaningful multiple compression
• ◆PE-driven acquisition multiple inflation (5–6x → 8–9x) eroding Stream B value and breaking M&A flywheel
• ◆Tariffs on building materials (steel, aluminum, petrochemicals) creating margin friction despite 60–90 day pass-through lag
• ◆2008-style severe housing recession (low probability ~10% but non-zero; IBP compresses to $80–90)
• ◆Acquisition integration failures clustering in single year triggering goodwill impairment and undermining M&A narrative
