Is IAG.L undervalued? Our fair value estimate
International Consolidated Airlines · Industrials · LSE
How we got here
The estimate is computed from IAG.L's reported fundamentals, with a growth assumption that is deliberately capped: small changes to an uncapped growth or terminal assumption can justify any price, and a number that can justify anything means nothing. These are the inputs the model holds for IAG.L today; the exact method, and where it goes wrong, is on the methodology page.
The starting point is earnings power: what the business earns per share, and what the market currently pays for each unit of it.
The trailing growth rate informs the growth assumption, which the model caps deliberately: uncapped growth assumptions can justify any price.
Wall Street's published earnings growth forecast, used as context for the capped growth assumption, never swallowed whole.
Margins tell the model how much of each unit of revenue survives as profit, and how much room there is for that to erode.
A volatility measure against the wider market. A jumpier share earns a larger discount for risk, which lowers the estimate.
Leverage haircuts the estimate: debt claims cash before shareholders do, and it turns bad years into dangerous ones.
Wall Street's number, next to ours
The mean analyst price target for IAG.L is £5.15 across 16 analysts, which implies +16.5% from the current price. Our estimate is £10.36. They answer different questions: an analyst target is a 12-month price prediction averaged across banks; ours is a model's view of what the business is worth, with every assumption published. When they disagree, at least one of us is wrong.
