AAON (AAON) Could Be 45% Undervalued After Its Sharp 3 Month Slide

Simply Wall St · 1d ago

AAON (AAON) drew fresh attention after recent trading moves left the stock down about 16% over the past month and roughly 34% over the past 3 months, despite reporting positive annual revenue and net income growth.

Despite the recent slide, AAON’s 1-year total shareholder return of 2.02% and 3-year total shareholder return of 27.76% point to a stronger longer-term record. At the same time, the 1-day and 7-day share price returns of 1.82% and 5.37% hint at stabilising momentum after a sharp pullback.

Pressure test AAON’s recent pullback against other industrials by scanning a curated set of list of solid balance sheet and fundamentals (24 results) that have also held up through choppy trading.

Bulls point to AAON’s revenue and net income growth, along with a long record of positive shareholder returns. Bears focus on the 34% three month slide. Which side does the current valuation actually support?

Most Popular Narrative: 44.5% Undervalued

Against AAON's last close of $79.40, the most widely followed narrative pins fair value at $143.00, which implies a large gap that rests on aggressive growth and margin assumptions.

Ongoing investments in new manufacturing capacity and automation (for example, the Memphis facility) are expected to nearly double BasX capacity by year-end, removing current operational constraints and shifting from near-term cost drag to profit contribution by 2026 as orders ramp, supporting long-term operating leverage.

Read the complete narrative.

Want to see what has to go right for that kind of upside to make sense? The narrative leans on rapid top line expansion, sharply higher profitability, and a premium earnings multiple that assumes AAON keeps converting its project pipeline into sustained cash generation.

Result: Fair Value of $143 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

Still, the narrative wobbles if AAON’s ERP rollout keeps disrupting factories or if heavy BasX and Memphis spending drags on cash flow longer than expected.

Another View: AAON’s Price Tag On Earnings

The story looks different when shifting from cash flow models to what investors are currently paying for AAON’s earnings. The stock trades on a P/E of 41.1x, which is richer than both the peer average of 28.3x and the US Building group on 21.8x.

At the same time, the fair ratio sits higher at 48.6x. That indicates the market is already paying a premium, yet could still move closer to that fair ratio if the bullish narrative plays out. Alternatively, it could drift back toward peers if growth or execution underwhelms.

Before leaning on this comparison too heavily, it helps to see how the full valuation stack fits together across other checks and assumptions. See what the numbers say about this price — find out in our valuation breakdown.
