Comfort Systems reported Q3 2026 earnings of $13.91 per share, beating consensus estimates by 9.44%, with revenues of $3.77 billion exceeding expectations by 12.45%. The stock has gained 50.1% year-to-date.

However, the company received a Zacks Rank #3 (Hold) rating due to mixed estimate revisions, and its industry ranks in the bottom 31% of Zacks industries. Lennox International is expected to report results on October 28 with projected earnings of $7.18 per share.

Dycom Industries' Building Systems segment delivered exceptional Q2 results with a 24.5% adjusted EBITDA margin and $97.2M EBITDA on $397.5M revenue, driven by strong data center demand. The company raised fiscal 2027 revenue guidance to $1.58-$1.65B but expects margins to normalize to high teens-low 20s. Industry peers Sterling Infrastructure and Comfort Systems USA are similarly capitalizing on data center infrastructure demand with strong margin expansion.

During the recent AI stock correction, three companies present compelling buying opportunities: Sandisk, a NAND flash memory leader down 30% despite quadrupling revenue; Nebius, a neocloud provider down 30% but commanding higher rates ($40-50M per megawatt) with strong prepayment deals; and Comfort Systems USA, down 20% but benefiting from 51% YoY revenue growth and a $14B backlog in data center construction and maintenance.
