ALGT · Allegiant Travel

The thesis

Allegiant Travel Company is modestly more likely than not to beat the S&P 500 over the next three months, because unit revenue is rising faster than fuel costs. The investor day on 7 December 2026 tests that view. It should show whether the 2027 capacity, cost and integration targets support the full-year 2026 adjusted earnings per share (EPS) guide of more than $6.00.

The third-quarter report on 4 November 2026 is the base of the case. Revenue was $962 million, up 71.1% from a year earlier with Sun Country Airlines included (10-Q filed 6 November 2026). The adjusted loss of $0.03 a share beat the $0.53 loss analysts expected (Benzinga, 4 November 2026). Fourth-quarter adjusted EPS was guided to $1.00–$1.50, above the $0.79 estimate. The guide assumes jet fuel at $4.75 a gallon, up from the $3.70 assumed at the previous call (Finviz summary of the release and call).

Fuel is the open question. Argus put the average US jet fuel price at a record $4.90 a gallon on 22 October 2026 (NPR, 23 October 2026), above the company's fourth-quarter assumption. The rating is Medium because higher fares are offsetting fuel costs so far. The 1.1% operating margin of the latest quarter leaves little room for error.

Bullish and bearish views on Allegiant Travel Company

The bull case on Allegiant Travel Company (ALGT), in brief: unit revenue is rising quickly. The bear case: fuel is running above the guide's assumption.

Bull case

• Unit revenue is rising quickly. Pro forma total revenue per available seat mile rose 28.3% in the third quarter on 5.7% less capacity, and management guided fourth-quarter growth above 20% (Finviz summary of the 4 November 2026 release).
• Non-fuel costs came in below guidance. Non-fuel unit cost rose 9.1% in the third quarter, under the 10%–12% management had guided. Management said the third quarter should be the peak of cost pressure (Finviz, 4 November 2026 call).
• The fourth-quarter guide sits above consensus despite dearer fuel. Adjusted EPS of $1.00–$1.50 and an adjusted operating margin of 6%–7% assume $4.75 fuel, against $3.98 realised in the third quarter (Finviz; Benzinga, 4 November 2026).
• The credit-card income stream is secured. On 12 November 2026, Bank of America extended the Allways Rewards co-branded card into the next decade (company announcement). Third-quarter co-brand remuneration was $42.1 million, up 23.6% (Finviz).
• Analysts raised their targets after the report. UBS raised its target to $120 from $107 and kept a Buy rating on 12 November 2026. Bank of America raised its target to $100 from $85 on 10 November 2026.

Bear case

• Fuel is running above the guide's assumption. Argus's record $4.90 a gallon on 22 October 2026 was above the $4.75 the fourth-quarter guide assumes (NPR, 23 October 2026). The full-year EPS guide of more than $6.00 was reaffirmed, not raised. It had been above $8 at the start of 2026 (Finviz).
• Profit is thin on the reported figures. In the quarter to 30 September 2026, the operating margin was 1.1%, pre-tax income was a $20 million loss and net income was a $15 million loss (10-Q filed 6 November 2026). The generally accepted accounting principles (GAAP) loss per share was $0.56, including $19.1 million of special charges (Finviz).
• Sun Country is still marginal and shrinking. Sun Country's adjusted operating margin was 1.1% in the third quarter, and its scheduled service is expected to fall about 10% in the fourth quarter because of pilot shortages (Finviz).
• The balance sheet is heavier. Debt was $2,938 million against $854 million of cash and short-term investments on 30 September 2026. Free cash flow over the four quarters to 30 September 2026 was minus $26 million (10-Q). Liquidity fell to $1.1 billion after a $267 million pilot retention payment. Capital spending in 2027 is expected to exceed the roughly $850 million of 2026 (Finviz).
• Insiders sold after the report. The chief executive, Gregory Anderson, sold 2,640 shares at $92.92 on 12 November 2026. Directors Linda Marvin and Charles Pollard sold 2,000 shares at $97.17 on 9 November 2026 and 10,000 shares at $93.04 on 6 November 2026 (SEC Form 4 filings). Three sales are too small a sample to show what insiders expect.

Price setup

The shares closed at $92.15 on 13 November 2026. That is down from $97.21 on 9 November 2026, the highest close after the report, and 25.5% below the 52-week intraday high of $123.63 set on 2 July 2026. The 52-week closing low is $61.77, from 20 November 2025. The three-month price change is 9.3%.

The last close sits above both the 200-day moving average of $87.52 and the 50-day moving average of $77.51. A common market view is that the 200-day average acts as a floor. A close back under it would show the post-report gain fading toward the level where the shares traded before the report.

The spread of three-month returns across US stocks trading at least $5 million a day was 27% (standard deviation) in 2026, so single-name outcomes over this window are wide.

Catalysts ahead

• 18 November 2026: EIA Weekly Petroleum Status Report, including jet fuel spot prices (published each Wednesday). Shows whether jet fuel is holding above or falling back under the $4.75 a gallon behind the fourth-quarter guide of $1.00–$1.50 adjusted EPS.
• 7 December 2026: Allegiant investor day. Management plans to give integration milestones and a long-term financial framework. 2027 capacity and cost targets decide whether earnings estimates rise or the above-$6.00 2026 guide comes into doubt.
• ~3 February 2027 (est.): Fourth-quarter and full-year 2026 results. Shows whether fourth-quarter adjusted EPS landed within $1.00–$1.50 at the fuel price actually paid, and whether Sun Country's margin rose from 1.1%.

What would change the view

A daily close below $80.00, which would erase most of the gain after the 4 November 2026 report and put the shares well under the 200-day average. A cut to the full-year 2026 adjusted EPS guide of more than $6.00 would also show the call is wrong.

The risks this note tracks, each with what would confirm it:

• Jet fuel stays above the $4.75 a gallon fourth-quarter assumption, so fourth-quarter earnings miss the $1.00–$1.50 guide and the above-$6.00 full-year figure is missed. Confirmed by: US jet fuel prices in the weekly EIA series holding above $4.75 through December 2026, or a guide cut at the 7 December 2026 investor day.
• Holiday fares that are up 20%–30% start to reduce leisure demand, and unit revenue growth slows. Confirmed by: management lowering its fourth-quarter guide of more than 20% unit revenue growth, or cutting 2027 capacity below the low-to-mid single-digit growth framed on the 4 November 2026 call.
• Sun Country pilot shortages cut capacity and keep the acquired airline near breakeven longer than planned. Confirmed by: Sun Country scheduled service falling by more than the roughly 10% expected for the fourth quarter, or its adjusted operating margin staying near the 1.1% reported for the third quarter.
• Leverage and capital spending leave little room for error after the $267 million pilot retention payment. Confirmed by: liquidity falling below the $1.1 billion reported for the third quarter, or 2027 capital spending guided well above the roughly $850 million of 2026.

What it trades with

The shares trade with US leisure airlines and with jet fuel prices. Fares are the offset. Hopper data show Thanksgiving fares up about 30% and Christmas fares up more than 20%, and Delta's chief executive said customers have shown limited resistance to fare increases (NPR, 23 October 2026). Frontier Group (ULCC) faces the same fuel cost on a similar leisure-heavy customer base. Allegiant's own fleet costs are tied to Boeing (BA): on 23 October 2026 the company exercised options for six 737-8 aircraft for more than $720 million. Sun Country has been consolidated since May 2026, so comparisons with a year earlier include acquired results.
