# Gibraltar to sell D.S. Brown infrastructure unit to Saint-Gobain for $208M cash; close seen in Q4 2026

## Summary
- Securities Purchase Agreement dated Oct 14, 2026 calls for D.S.B. Holding Corp. to sell all DSB stock to GCP Applied Technologies Inc., an affiliate of Saint-Gobain.
- Buyer pays $208.0 million in cash at closing, subject to customary working capital, indebtedness, cash and transaction expense adjustments; Gibraltar is party only for insurance/tax indemnity terms.
- Closing expected before end of calendar year 2026, conditioned on HSR antitrust clearance, no injunction and accurate reps; no Gibraltar stockholder vote required.
- Either side may terminate if closing has not occurred by Jan 31, 2027, subject to up to five automatic 30-day extensions for HSR delays; material breach gives a cure-period termination right.
- Chairman/CEO Bill Bosway cites portfolio simplification and focus on building products and structures; expected highly tax efficient proceeds will accelerate debt reduction entering 2027.
