LATAM Airlines: The Fuel Shock Was the Test. It Passed.

The market is still pricing LATAM Airlines as if jet fuel is its existential threat. The numbers say otherwise. In the second quarter, fuel costs nearly doubled — the single biggest shock in the company's recent history — and management raised its full-year earnings forecast. That's the inflection. The setup is clean enough to attach a target, a timeframe, and a tripwire.

The old story: fuel kills the margin

LATAM built its turnaround on pricing power, a growing loyalty ecosystem, and a modernizing fleet. But the narrative that kept investors cautious was always the same: this is an airline, and fuel is its kryptonite. When oil spiked in mid-2026 due to geopolitical conflict in the Middle East, that old fear got validated. At least on the surface.

Second-quarter fuel expenses surged 93.1% year-over-year to $1.7 billion. The all-in fuel price the airline paid — hedging included — reached $194.50 per barrel, up from $107.10 a year earlier. CFO Ricardo Bottas estimated the headwind at more than $800 million in a single quarter. Adjusted operating income fell 46.3% to $227 million, and the adjusted operating margin compressed to 5.4% from 12.9%.

The tape read like exactly the scenario bears had been waiting for. Fuel spikes, margins collapse, guidance gets slashed. Instead, management raised the 2026 adjusted EBITDA forecast to $4.1–4.4 billion, up from the $3.8–4.2 billion range it issued in May.

That reversal is the whole point.

The proof path: revenue elasticity and a cleaner second half

The guidance upgrade isn't a management artifice. It's driven by two concrete things.

First, the fuel assumption for the second half improved dramatically. LATAM now expects jet fuel at $147 per barrel in Q3 and $130 in Q4, down from $170 and $150 respectively at the May forecast. That's still well above the pre-conflict assumption of around $90 a barrel, but the second-half burden is materially lighter than what the market feared in June and July.

Second, the revenue side proved resilient. Total revenue climbed 27.6% to $4.18 billion. Passenger revenue per available seat kilometer (PRASK — the unit revenue measure that tells you how much income each seat generates per kilometer flown) rose 17.5% to 8.1 cents. The airline passed fuel increases through fares without weakening demand. Premium cabins now account for 29% of passenger revenue, up 2 percentage points from Q1, and are growing faster than the main cabin. The load factor held at 81.8% despite an 8.9% expansion in capacity.

The cost shock hit, but the revenue engine absorbed it. That's the proof point: LATAM can grow capacity, raise fares, and still fill planes. The business model doesn't break when fuel moves.

The full-year picture reinforces this. Adjusted EBITDA guidance of $4.1–4.4 billion implies a 23–25% margin on projected revenue of $17.3–17.7 billion. The midpoint EBITDA of $4.25 billion would represent roughly 60% growth over the roughly $2.6 billion in adjusted EBITDA the airline generated in all of 2025. If fuel behaves as management now expects, the margin expansion is structural, not cyclical.

The cash flow is already telling the better story

Trailing-twelve-month free cash flow stands at $2.1 billion, up 55.5% year-over-year. Operating cash flow for the TTM period is $3.74 billion against $1.63 billion in capital expenditures. The balance sheet shows $2.7 billion in cash, total liquidity above $4.2 billion, and adjusted net leverage at 1.5x — comfortably below the 1.6x ceiling set by financial policy.

That liquidity position matters because it means LATAM can fund the E2 fleet build, withstand another fuel spike, and execute the new 5% share repurchase program (up to 5% of outstanding shares over five years) without stress. The company paid a $38 million dividend in Q2 and is positioned to generate at least $1.3 billion in adjusted levered free cash flow for the full year.

The market hasn't caught up

LATAM's stock sits at $56.72, down roughly 5% over the past 120 days and essentially flat on a 20-day basis. The stock is trading at 10.4x trailing earnings, 5.7x EV/EBITDA, and a PEG ratio of 0.25 — meaning you're paying roughly a quarter of a dollar for each dollar of earnings growth. That multiple compression happened as investors anchored to the fuel narrative instead of reading the guidance revision.

The stock is pricing in a company that gets hammered when oil moves. The operating data is showing a company whose revenue growth and loyalty ecosystem (56 million LATAM Pass members now generate 67% of passenger revenue) insulate it from exactly that kind of shock.

The target

If the midpoint EBITDA of $4.25 billion holds — and the upper end of $4.4 billion is achievable if fuel cooperates — applying a forward EV/EBITDA multiple of 7x to the upper-end figure gets you to roughly $30.8 billion in enterprise value. LATAM's current enterprise value is $13.6 billion. The implied equity value at that multiple would be around $33.4 billion, or approximately $68 per share.

That's roughly 20% upside from current levels over a 12-month window. The math doesn't require fuel to fall back to pre-conflict levels. It just requires fuel to behave at or near the $130–147 range management is now assuming for the second half, and for the 9–10% capacity growth plan to execute without a demand collapse.

AInvest's aggregate signal labels the stock Buy, which is consistent with the fundamental improvement but doesn't capture the speed of the inflection. The composite analysis rating of 1.39 and fundamental rating of 6.22 reflect the improving earnings power, but the market hasn't moved yet.

The Brazil multiplier

The Embraer E195-E2 fleet deployment starting in November adds a structural growth driver that most investors are still processing. LATAM is rolling out 24 firm aircraft across 42 domestic routes, expanding its Brazilian network to 67 destinations — the largest in the company's history, up from 44 in 2019. The E2 jets burn roughly 20–25% less fuel per seat than the older Embraer E-Jets they're replacing on thinner routes. That matters directly: better cost efficiency on the domestic network where LATAM faces the most competition, precisely as fuel costs remain elevated.

Management is evaluating 18 additional destinations for a second phase in 2027. This isn't just capacity growth. It's market share accumulation in Brazil, where LATAM has historically been weaker than its domestic rivals.

The tripwire

This thesis breaks if fuel prices don't recede toward the $130–147 range management is assuming. If crude holds above $100 per barrel through the end of the year — pushing LATAM's all-in fuel price back toward Q2 levels — the EBITDA guidance becomes untenable and the margin compression returns. The tripwire is a second-half quarter where adjusted operating margin falls below 5% on sustained fuel costs, which would signal the revenue elasticity is real but the cost structure isn't resilient enough.

A secondary risk is demand. The FIFA World Cup disrupted June travel patterns across South America, and management flagged economic weakness in Chile and slowing demand in Argentina. If those soften into a broader Latin American travel slowdown, the capacity growth plan becomes a margin killer rather than a growth engine.

The action

The market is still pricing the old risk profile while the operating setup is already getting cleaner. The entry is here, the bridge is explicit, and the tripwire is visible. I can be wrong again — fuel is always a wildcard — but the setup is a company that just absorbed an $800 million quarterly headwind, raised its full-year forecast, and is sitting at a PEG ratio of 0.25.

$68 over 12 months. Cut if a second-half quarter shows operating margins below 5% on sustained fuel costs.
