Conviction · Low · more likely to lag the S&P 500 over the next three months
Wrong if: a daily close above $9.62
Note written ·
Price against the kill line
21.1% clear of its kill line on the 13 November 2026 close.
How to read this
This note expects the shares to lag the market, so its kill line sits above the price: a close above the red mark would prove the view wrong. Prices run from low on the left to high on the right. The dot is where the stock closed on 13 November 2026, left of the mark while it is below the line; a dot right of the mark has closed through it.
The scale is stretched near the line, so close calls are easy to see. More than 8% from the line, the stock reads well clear, with a hollow dot to show the figure is off the drawn scale.
The kill line is the research note's own test. The portfolio sells on business facts, not on a price. How the portfolio decides
Three months against the kill line
Daily closes, to . Red: the kill line, a daily close above $9.62, on record since 11 November 2026. The shares are up 19.5% since the close; the S&P 500 is down 2.1% over the same sessions. Figures in the note can cover a different window.
Kill line
A daily close above $9.62, well above the 9 November 2026 intraday high of $8.53, would show the shares leading the S&P 500. Fourth-quarter adjusted EPS above the $0.05 top of the guide would also prove the call wrong.

The thesis
Frontier Group Holdings, parent of Frontier Airlines, is more likely to lag the S&P 500 over the next three months. The shares have already priced in a strong revenue recovery: they trade above most analysts' targets set after the third-quarter report. Fourth-quarter earnings guidance was cut, and fuel is guided at $4.75 a gallon. The fourth-quarter report, expected in early 2027, will show whether revenue per seat can outrun that fuel cost.
The shares closed at $7.70 on 12 November 2026, down from $8.08 on 11 November 2026 and $8.35 on 9 November 2026. Seven company officers sold shares on the open market between 5 November 2026 and 11 November 2026, at prices from $6.92 to $8.40, according to SEC Form 4 filings. Chief Financial Officer Mark Mitchell sold 40,798 shares at $8.15 on 11 November 2026. Only one of the seven filings, Trevor Stedke's, says the sale was made under a pre-arranged Rule 10b5-1 trading plan.
The rally rests on a strong quarter and one upgrade. Third-quarter revenue was a record $1,355 million, up 53%, and adjusted earnings were $0.18 a share against a company guide of $(0.10) to $0.10, per the 28 October 2026 release. Deutsche Bank analyst Michael Linenberg raised the stock to Buy from Hold on 5 November 2026, with a $10 target, per Benzinga and fiscal.ai.
The rating is Low because the share price already sits above most post-report analyst targets and above the guided earnings path. Officers sold during the climb, and no company report is due before early 2027.
Bullish and bearish views on Frontier Group Holdings, Inc.
The bull case on Frontier Group Holdings, Inc. (ULCC), in brief: revenue per seat is rising fast. The bear case: officers sold into the rally.
Bull case
- Revenue per seat is rising fast. Revenue per available seat mile (RASM, revenue earned for each seat flown one mile) was 11.87 cents in the third quarter, up 30%. The 28 October 2026 release guides fourth-quarter RASM up more than 20%.
- The third quarter beat estimates. Adjusted earnings per share (EPS) of $0.18 compared with an analyst estimate of $(0.04). Revenue of $1.355 billion compared with an estimate of $1.287 billion, per Benzinga on 28 October 2026.
- Analysts raised targets after the report. Deutsche Bank set a $10 target on 5 November 2026. UBS raised its target to $7 on 30 October 2026, and Susquehanna raised its target to $6.50 on 29 October 2026.
- Cost savings while growth slows. The chief executive said on 28 October 2026 that the company is on track for $200 million of annual run-rate cost savings by 2027, with capacity growth of about 5% to 7% next year. Fourth-quarter capacity is guided up 5% to 6%, against 18% in the third quarter.
- Premium seating and new management. Frontier opened First Class reservations on 10 November 2026 and added extra-legroom Premium seats and in-seat power. Michael Delehant becomes chief operating officer on 30 November 2026, and James Fenner was promoted to chief revenue officer on 2 November 2026.
Bear case
- Officers sold into the rally. SEC Form 4 filings show seven open-market sales by officers between 5 November 2026 and 11 November 2026. They include the chief financial officer (40,798 shares at $8.15), the head of legal and corporate affairs (35,401 shares at $8.40) and the chief marketing officer (37,914 shares at $6.92). No purchases by officers appear in those filings.
- High fuel guide. Frontier assumes fuel will cost $4.75 a gallon all-in in the fourth quarter. Third-quarter fuel averaged $3.96 a gallon, up 56% from $2.54 a year earlier, per the 28 October 2026 release.
- Earnings guidance was cut. The fourth-quarter adjusted EPS guide fell to $(0.15) to $0.05, from $0.00 to $0.20. Its midpoint of $(0.05) matches the analyst estimate Benzinga cited on 28 October 2026.
- Losses under standard accounting continue. The third-quarter net loss under generally accepted accounting principles (GAAP) was $104 million, or $(0.45) per diluted share, per the 28 October 2026 release.
- The price is above most targets. The $7.70 close on 12 November 2026 is above UBS's $7 and Susquehanna's $6.50 targets. Only Deutsche Bank's $10 target is higher.
- Fleet charges and liquidity. A 25 August 2026 Form 8-K disclosed $90 million to $120 million of cash charges for returning 13 A320neo aircraft early. Total liquidity was $1.18 billion on 30 September 2026.
Price setup
The shares closed at $7.70 on 12 November 2026. That is 9.7% below the 52-week intraday high of $8.53, set on 9 November 2026, the day of the highest close of the run at $8.35. The three-month change is 15.1%, measured from a $6.69 close on 14 August 2026. The 52-week closing low was $3.10 on 18 March 2026.
The last close is well above both the 50-day moving average of $6.03 and the 200-day moving average of $5.53, as of 12 November 2026. Most of the gain came in a few sessions. The shares closed at $7.12 on 5 November 2026, the day of the Deutsche Bank upgrade, then rose to $8.35 by 9 November 2026. They fell in each of the next three sessions.
The officer sales on 9 November 2026 ($8.40), 10 November 2026 ($8.35) and 11 November 2026 ($8.15) happened near the top of the price range. The 50-day moving average, which has not been retested since the run began, is the nearest reference below the price. No earnings date falls within the next 30 days.
Catalysts ahead
- 30 November 2026: Michael Delehant starts as executive vice president and chief operating officer. A new operations chief takes over as fourth-quarter capacity growth slows to 5% to 6%, and as the airline pursues $200 million of run-rate cost savings by 2027.
- ~February 2027 (est.): Fourth-quarter 2026 results, date not yet announced. Will show realized fuel cost against the $4.75 a gallon assumption and adjusted EPS against the $(0.15) to $0.05 guide. It is also the first test of the 2027 capacity and cost-savings plan.
What would change the view
A daily close above $9.62, well above the 9 November 2026 intraday high of $8.53, would show the shares leading the S&P 500. Fourth-quarter adjusted EPS above the $0.05 top of the guide would also prove the call wrong.
What it trades with
Frontier trades with other US airlines and moves opposite to jet fuel and crude oil. Airline shares rose together on 2 November 2026 and 9 November 2026, per Benzinga, so part of this month's move was sector-wide. Frontier's earnings are more sensitive to fuel than those of larger carriers. Its guidance is indexed to the fuel price, and all 164 aircraft in its fleet are on operating leases.
