AerCap Holdings (AER) has drawn fresh attention after reporting Q1 2026 results that exceeded analyst expectations, raising full year earnings guidance and pairing this with a new US$1.0b share repurchase program.

Despite the strong Q1 update and new capital return plans, AerCap’s recent 90 day share price return of a 3.01% decline contrasts with a 1 year total shareholder return of 33.28%, indicating longer term momentum remains stronger than the latest short term moves.

With AerCap posting record Q1 earnings, lifting full year guidance, and pairing that with fresh buybacks and dividends, the real question now is whether the current share price still leaves upside or already reflects future growth.

Most Popular Narrative: 13% Undervalued

The most followed narrative currently points to a fair value of $162 for AerCap versus the last close at $140.94, framing Q1’s strength against a longer term earnings reset story.

Analysts are assuming AerCap Holdings's revenue will remain fairly flat over the next 3 years. Analysts assume that profit margins will shrink from 44.0% today to 29.2% in 3 years time.

Want to see what keeps the fair value well above today’s price even with lower future earnings baked in? The narrative leans on margin compression, slower revenue, and a higher future earnings multiple to tie the numbers together. The full story connects these moving parts in a way raw forecasts alone do not show.

Result: Fair Value of $162 (UNDERVALUED)

However, you still need to weigh risks such as a possible aircraft oversupply that pressures lease rates and customer distress that could trigger credit losses or impairments.

Another Angle: DCF Flips The Story

While the popular narrative sees AerCap as 13% undervalued at a fair value of $162, the Simply Wall St DCF model points the other way, with an estimated future cash flow value of $92.80 versus a $140.94 share price, implying AerCap screens as overvalued on this measure.

For investors, that kind of gap raises a simple question: are earnings based valuations too optimistic, or is the DCF model too cautious about future cash flows and margins?
