Trex Company (TREX) raised its second quarter and full year 2026 guidance, while also naming Specialty Building Products as its sole national distributor. This combination puts near term revenue expectations and market access in sharper focus.

The updated guidance and expanded Specialty Building Products partnership come after a mixed performance, with the share price gaining 21.21% year to date but the 1 year total shareholder return declining 36.59%. This indicates that longer term momentum has been weaker than recent trading suggests.
