Setup

Gibraltar Industries (ROCK, ≈$1.15B cap) closed a transformative $1.335B all-cash acquisition of OmniMax International on February 2, 2026 — doubling down on residential building products with $1.3B of new debt. Today's 8-K/A amendment filed the required audited OmniMax standalone and pro forma combined financials, producing the first public look at the target's books. Only two sell-side analysts cover the combined company.

What the filing says

OmniMax FY2025 standalone: revenue $517.6M, operating income $38.5M, OCF -$6.6M (vs +$12.0M in 2024). The target carried $620.9M debt at SOFR+5.75% (9.9% avg rate) under PE ownership. Gibraltar refinanced at SOFR+2.00-2.25%, unlocking an estimated ≈$23-25M annual pre-tax interest savings. Pro forma combined FY2025: net sales $1.653B, operating income $129M, net income $36.9M. Reported pro forma EPS: $1.23 — suppressed by $41.4M of OmniMax intangible amortization ($530M customer relationships / 15yr + $110M trade names / 18yr). Add back after-tax ≈ $2.33 adj EPS, before rate arb flowing through and before $27-35M synergy run-rate (excluded from pro forma by company election).

Separately, CEO Bosway bought 7,000 shares for $273K (avg $39.15) between March 9-13, and Director Metcalf bought 12,444 shares for $502K at $40.35 on March 10 — both code P open-market, verified via primary Form 4.

What the market thinks

Forward P/E on GAAP pro forma ≈ 32x. On fully-loaded adj cash EPS ($2.33 + rate arb $0.55 + partial synergies $0.40 → ≈$3.25-3.75 by 2027): 10-12x. Analyst targets $65-86 (n=2). Options thin — max pain $45 (May 15 expiry), 125-day IV 64.9%, implied P(-25% drawdown by Aug 21) ≈ 27%. Our view of that tail: 10-12%.

Why the gap exists

Three reasons, ranked:

1. Coverage gap. 2 analysts on a now-$1.65B revenue company. Slow consensus formation.
2. GAAP optics. Pro forma $1.23 headline anchors screens to 32x P/E. The $41.4M non-cash amortization and excluded synergies mask cash earnings.
3. Cyclical skepticism. Residential BP cycle at trough (HMI 36, ABI <50 for 13 months). Market pricing it as broken, not bottoming.

Cross-ticker evidence recontextualizes point 3: $9.1M director-level open-market buying across 5 residential BP peers in the same 9-day window — BLDR Director Levy $4.38M, POOL Director Perez De La Mesa $2.1M, PATK Director Welch $1.14M, ROCK $775K, GFF Director Alpert $80K. Five independent boards triangulating the same cyclical-trough thesis.

Risks (ranked by impact)

1. OmniMax was burning cash under PE. FY2025 OCF -$6.6M. Three nested acquisitions (Millennium Dec-24, Hancock Feb-25, Nu-Ray Oct-25 = $250M in 10 months). Gibraltar inherits three still-integrating deals inside the one it's integrating.
2. Leverage. 3.7x post-close, covenant steps 5.25x → 4.25x. Interest burden $75-85M/year. $1.3B at SOFR = $1.6M per 1/8% rate move.
3. HMI retailer channel -7.8%. Sector-wide per FBIN/GFF/TTAM commentary. Exogenous, not execution failure, but not resolved.
4. Renewables racking/foundations sale. June 30 management deadline, no buyer identified, weak solar market (ITC uncertainty).

Catalysts

• ~May 6-8: Q1 2026 earnings, first combined quarter. Tests synergy pace and organic trajectory.
• ~June 30: Renewables disposition deadline (70%).
• Mid-May: HD/LOW Q1 earnings — Pro vs DIY split adjudicates the cycle-bottom thesis.

What would change our mind

• Q1 2026 synergy guide REDUCED (vs $27M near-term / $35M by 2028) → integration behind plan
• HD/LOW Q1 prints show DIY weakness worsening AND Pro momentum fading → cycle not bottoming
• Renewables sale fails or requires further impairment → deleverage path breaks
• CEO/Director sell any shares post-Q1 → insider conviction was bottom-fishing, not cycle-bottom conviction

Evidence

Memo LR: 1.5 — bullish, market underweighting the GAAP/cash optics gap and the cross-ticker insider signal. Direction high-confidence; magnitude capped by honest acknowledgment that idio is ≈42% and this is a factor trade with a coverage-gap kicker, not pure stock-specific alpha.
