AAON is one of the most attractive earnings gappers because data center demand has pushed its backlog to a record $2.1B. It beat and raised, with a 65% EPS surprise and a 29% revenue surprise, and lifted its FY26 revenue growth outlook to 40-45% from 18-20%. x.com 

AAON offers data-center cooling exposure growing more than twice as fast as Vertiv at the same forward P/E: its BASX data center brand grew 216% last quarter and is now half the company. AAON trades at 30.2x forward earnings, growing 55-60% with a $2B backlog up 98%, versus Vertiv at 31.8x growing 23%. Its record-low multiple reflects costs at a new Memphis plant not yet full, while BASX margins rose to 30%. It is the earlier, riskier name, with three customers and a plant to fill. x.com 

AAON is a favorite HVAC stock and one of the best long-term compounders, rising over 20% a year for 20 years, and jumped 43% on earnings today. There is speculation that Amazon's proprietary data-center liquid cooling uses AAON, which should lift the stock if confirmed. It is volatile around earnings, so a 20% drop next time would be a chance to buy. x.com 

Vertiv's surging orders and Q3 growth show AI infrastructure demand exceeding expectations. Per WallStEngine, revenue rose 61% to $4.3B, adjusted EPS rose 78% to $2.21, organic orders grew more than 100%, and FY26 guidance was raised above estimates. Vertiv is delivering into accelerating demand for its power and cooling equipment. x.com  x.com 

Vertiv's power and cooling gear is benefiting from the AI data-center build-out. Q3 net sales rose 61%, operating profit 90% and net income 92%. There is no more direct picks-and-shovels bet on AI infrastructure than Vertiv. Grade: A. x.com 

AI data-center spending flows beyond GPUs and operators into networking, optics, power and cooling. Nvidia, AMD, Broadcom and Marvell supply chips; Arista, Nokia and Credo connectivity; Applied Optoelectronics and Lumentum optics; Vistra, Constellation and Bloom power; Vertiv and Modine cooling. Meta's $140B spending this year illustrates the scale, per a commenter with whom the point is agreed. x.com  x.com 

AI data centers need cooling, electricity and transmission, sustaining the case for Vertiv, GE Vernova and Quanta Services. Vertiv's sales rose 26% in the past year; its systems cool AI chips. GE Vernova is the go-to power trade for its gas turbines. Quanta builds the lines to data centers and has a record $53B backlog. x.com  x.com  x.com 

Comfort Systems USA remains a bullish holding, reaffirmed here with a shared link and no new argument. x.com 

Record data-center construction supports Sterling Infrastructure, Quanta Services, Comfort Systems USA, Vertiv and Argan. Per The Kobeissi Letter, US data-center construction spending jumped 46% YoY in June to a record $68 billion annualized rate, up 158% since January 2024, and now exceeds office construction by a record $25 billion. Kobeissi calls AI the driver of the biggest investment wave in US history. x.com 

Vertiv's demand is accelerating, so GLJ Research's $188 target against a $255 stock and a consensus near $350 looks badly wrong. Vertiv's orders doubled and deferred revenue just posted the biggest jump in company history; customers prepaying at records is not how a cyclical downturn starts. GLJ's similar sell call on GE Vernova as a cyclical turbine maker failed: the stock now trades above $1,000, over double its target, and its CEO is selling delivery slots for 2032. x.com
