AerCap Trades at Book Value While Retiring 6% of Its Stock a Half — The Lessor Discount Has Stopped Making Sense

Aengus Kelly, AerCap's chief executive, offered the sharpest description of his own capital allocation on the July 29 earnings call: returning $1.4 billion to shareholders this year, he said, is the economic equivalent of buying roughly $5.5 billion of aircraft in the sale-leaseback market at prices the company could never match . That is the whole thesis in one sentence. AerCap is the largest owner of commercial aircraft on earth, leasing a fleet of jets and engines to roughly 300 airlines from Dublin, and the cheapest aircraft it can buy are its own shares — trading, as of the July 31 close at $150.90, at 1.27x a book value of $119.21 per share and about 8x a forward earnings stream that a durable, cash-generative specialty lender has no business trading at.

The market files aircraft lessors under a single reflex: a levered airline-cycle proxy, a balance sheet that only functions while capital markets stay open, earnings flattered by cycle-peak asset sales, a residual-value bet dressed up as an annuity. That framing is why AerCap changes hands at 7.3x trailing earnings while it compounds book value per share at a mid-teens rate and shrinks its float relentlessly. The argument here is that the reflex is wrong on the current evidence — not that the risks are imaginary, but that at this price they are more than paid for, and the re-rating toward where a business earning a mid-teens return on equity should trade is the base case, not the bull case.

What the Business Actually Is, and Why the Segment Map Is Deceptively Simple

AerCap reports as a single aviation-leasing operation — there is no divisional P&L to parse, which is itself worth understanding, because it means the economics live in the composition of the revenue line rather than in segment disclosure. The engine of value is basic lease rents, $1.677 billion in the...
