What AAON Bears Saw Before The Fall

AAON has spent 2026 in the headlines for record quarterly sales, soaring data center demand and a backlog that crossed US$2b, capped by a guidance hike and a new corporate identity as The Aaon Group. For AAON shareholders, the loss over the past year was 23.9%, including dividends. If you had bought on 16 October 2025, how much of that setback can be traced to what was on record then versus what only emerged later?

On Simply Wall St, a Narrative is an investor's thesis written down: the reasoning, plus the numbers it rests on. Run those numbers and you get an estimated Fair Value.

The Two AAON Stories Investors Had To Weigh

The shares cost US$100 at the start of the period, and AAON investors had to decide which story better matched what they saw in the business.

The bullish narrative pinned Fair Value at US$125. It leaned on deep vertical integration and a U.S. focused supply chain, which were expected to support faster recovery in production and margins as new R454B equipment rolled through the system.

The bearish view put Fair Value at US$90. It focused on elevated costs from aggressive capacity expansion, such as the Memphis facility, and the strain that could place on cash flow and profitability.

What The AAON Results Put To The Test

Record Q2 2026 net sales of US$627.0m, up from US$311.6m in Q2 2025, and profit of US$56.7m with net margin at 9.0% gave AAON investors firm backing for the higher-throughput, data center heavy bullish story. At the same time, management flagged capacity expansion and Memphis ramp-up costs, which kept the cautious narrative on execution risks in play. Overall, the evidence cut both ways.

The key assumption tested was whether higher backlog and new plants would translate into better profitability. For a different industrial stock, track revenue, absolute profit and net margin together across at least a year to see if expansion spending is turning into higher quality earnings or just bigger projects.

What You Are Paying For In AAON Today

AAON trades at US$73.73 today, and this Narrative’s Fair Value figure sits above that market price based on its own assessment. The argument leans on a large backlog, significant data center exposure, and substantial recent investment that the Narrative sees as undercredited.

For that view to work out, a buyer today would need AAON to convert its roughly US$2b backlog and added BASX and Memphis capacity into higher quality earnings and stronger cash generation.

"The main thing that has to go right is that AAON converts its approximately $2b backlog and large BASX and Memphis capacity into sustained, higher quality earnings and stronger cash generation despite current price and cost pressure."
