AAR (AIR) shares have been in focus after the company reported fourth quarter and full year 2026 results, with sales and earnings figures that differ from the prior year and appear to be influencing recent trading.

The strong full year earnings update has come alongside a 26.9% 90 day share price return and a 65.8% year to date share price return, while the 1 year total shareholder return of 91.9% and 5 year total shareholder return of about 306.5% indicate momentum has been building over both shorter and longer periods.

AAR’s jump in earnings and recent share price run put you at a crossroads. Is it better to commit capital after this move, or wait for a cooler entry point as the valuation picture unfolds next?

Most Popular Narrative: 4% Undervalued

AAR is trading at $140.04 against a widely followed fair value narrative of $145.20, which frames the recent share price run through a long term lens.

The analysts have a consensus price target of $145.2 for AAR based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the more bullish reporting a price target of $155.0, and the most bearish reporting a price target of just $128.0.

Want to see what sits behind that $145.20 fair value for AAR? The narrative leans on steady revenue expansion, rising margins and a richer earnings multiple. The specific growth path and profitability mix doing the heavy lifting are where the story really gets interesting.

Result: Fair Value of $145.20 (UNDERVALUED)

However, the AAR narrative still leans on commercial aviation demand and successful digital execution, so a weaker cycle or stumbles with platforms like Trax could quickly challenge it.

Another View On AAR Using Earnings Multiples

The analyst narrative frames AAR as about 4% undervalued at $140.04 against a $145.20 fair value. On simple numbers, though, the picture is less clear. AAR trades on a P/E of 29.4x versus a fair ratio of 28.2x, which points to the stock being a bit expensive instead.

That same 29.4x P/E looks cheaper than the US Aerospace & Defense industry at 37.9x and well below a 76.4x peer average. The gap suggests investors are already paying a premium to the fair ratio, yet still at a discount to sector and peers. Is that a margin of safety or a sign of higher valuation risk if sentiment cools?
