Simply put, AAON is firing on all cylinders. Its 2021 acquisition of BASX for roughly $200 million now looks like an absolute masterstroke, as the young unit just grew sales by 105% to reach $135 million in Q1 revenue. As the hyperscalers pile money into data centers for AI compute at a hard-to-fathom rate, AAON’s premium, customizable HVAC equipment and solutions are becoming an indispensable part of the AI revolution’s build-out.

That said, as awesome as this news is for AAON right now, investors need to beware that the hyperscaler’s blistering expansion plans will likely not last forever – or, at a minimum, will lead to brutal cyclicality at some point. However, there haven’t been any hints yet that the data center build-out is slowing, so I’m not going to say AAON’s good times are soon to end. It’s impossible to tell how long this cycle will (or won’t) last.

Trading at 61 times forward earnings, AAON’s valuation isn’t outrageous if its outsize sales growth continues – which isn’t a stretch given its booming backlog and BASX unit’s book-to-bill ratio of over 2. I’m fascinated by AAON and will be keeping a close eye on it, as it looks like a promising picks-and-shovels play to the AI revolution.
