ULCC Frontier Group Holdings, Inc. Insider Trading

10% owner Group Holdings - Frontier LLC sells 11,700,000 shares of ULCC at $7.20 for $84,240,000.00

Group Holdings - Frontier LLC divested 11,700,000 shares (34.0% of pre-transaction holdings) at $7.20 on 2026-07-09, reducing stake from 34,406,526 shares to 22,706,526 shares. The sale price of $7.20 sits within the 52-week range of $3.02–$8.40 and represents a -21.8% discount to the 52-week high. The company reported net income of $-272,000,000.00 on revenue of $992,000,000.00 in the latest quarter and was unprofitable over its most recent full fiscal year, with annual revenue growth of -1.4% year-over-year. The magnitude of this divestiture—reducing a major shareholder's position by over one-third while the company operates at a substantial loss—signals material intent to reduce exposure to Frontier Group Holdings.

Biffle Barry, then-CEO of Frontier (ULCC), sold 100,000 shares (631.8K remaining) in 2 transactions for $582.1K under pre-arranged 10b5-1 plan.

The transaction was executed under a pre-arranged 10b5-1 trading plan adopted on August 8, 2025, meaning the sales were scheduled in advance rather than discretionary. As a scheduled disposition under Rule 10b5-1, this filing reflects predetermined execution rather than a reflection of current market or company judgment at the time of sale.

Former CEO Biffle Barry sold 200,000 shares (21.5% of holdings) across 3 tranches for $1,058,414.65 via 10b5-1 plan

Biffle Barry, who was CEO at the time of filing, executed 3 separate sales totaling 200,000 shares for $1,058,414.65 at blended average price of $5.29, reducing holdings from 931,836 to 731,836 shares. The transactions were conducted under a pre-arranged 10b5-1 trading plan adopted on 2025-08-08, meaning the sales followed a scheduled program established prior to execution rather than discretionary decision-making.

As this activity is plan-driven rather than discretionary, the timing and execution reflect the mechanics of the pre-arranged schedule, not an opportunistic response to market conditions.

CEO Barry Biffle sold 631.8K shares (100% of holdings) for $3.5M at $5.62 blended average on 2025-09-02

Barry Biffle, CEO of Frontier Group Holdings, executed three separate sales totaling 631,806 shares for $3,548,651.66, completely liquidating his holdings. His prior trades at ULCC show a 100% well-timed 90-day pattern (5 of 5 prior sells declined 20.5% to 62.4% in the subsequent 90 days), and his cross-ticker track record reflects a 100.00% well-timed rate across 15 prior sells. The stock has declined 48.5% from its 52-week high of $10.06 to the current $5.18, suggesting the post-transaction price environment aligns with his demonstrated timing pattern. The company's fundamentals show quarterly revenue of $929,000,000.00 against a net loss of $-70,000,000.00, with an annual revenue growth of 5.2% but persistent unprofitability that may inform the CEO's complete exit decision.

SVP & CFO Mitchell Mark Christopher sells 158,803 shares (58.6% reduction) at $8.77 blended average

Mitchell Mark Christopher, SVP & CFO of Frontier Group Holdings (ULCC), executed 2 separate sales totaling 158,803 shares for $1,393,101.18 at a blended average price of $8.77 on February 19–20, 2025, reducing his holdings from 270,889 shares to 112,086 shares. The sales occurred above the current price of $7.94 and within the 52-week range; the stock has declined 6.8% over 30 days but gained 41.8% over 90 days. The reduction represents a substantial 58.6% decrease in his position size, the largest structural change in his disclosed holdings. With the company posting revenue of $935,000,000.00 and net income of $26,000,000.00, this large secondary-market transaction by a senior financial officer merits investor scrutiny to understand the motivations and any forward signals it may contain.

President Dempsey James sold 318.3K shares (64.9% of holdings) at $9.08 on 2025-02-18; stock now -13.3% from 52-week high.

President James G. Dempsey executed a substantial sale of 318,314 shares at $9.08, reducing his holdings from 490,419 to 172,105 shares—a 64.9% reduction in his ULCC position. The sale occurred near Frontier Group's 52-week high, with the stock since declining 13.3% from its $10.06 peak. Dempsey's cross-ticker track record shows his prior sells averaged a 90-day return of +47.4% with a well-timed rate of 33.33%, indicating that past sales have captured some stock strength before declines; however, his same-ticker history at ULCC is more mixed, with 2 of 4 prior measurable sales (Nov 2023) followed by strong gains while 1 (Aug 2023) coincided with substantial declines. The current transaction warrants attention as a material reduction by a senior executive at a point where the stock trades at a 21.80 P/E and has appreciated 55.7% over 90 days, but the lack of recent quarterly context on fundamentals limits inference about forward intent.

EVP Diamond Howard sells 370,457 shares at $8.94 avg, reducing stake by 58.4% to 263.7K shares remaining

Diamond Howard, EVP of Legal & Corporate Affairs at Frontier Group Holdings, executed 2 separate sales totaling 370,457 shares for $3,311,042.67 (blended average $8.94) on 2025-02-18 and 2025-02-19. This represents a 58.4% reduction in his holdings, cutting his position from 634,173 shares to 263,716 shares. The sales occurred near the company's 52-week high of $10.06, with the current price at $8.72 (13.3% below the high); notably, the stock has appreciated 55.7% over the past 90 days, suggesting the insider executed these sales during a period of strong recent momentum. Frontier Group's fundamentals show $935.0M in latest-quarter revenue, positive net income of $26.0M, and a P/E of 21.80; the substantial reduction in this executive's ownership stake warrants investor attention to understand the rationale behind such a significant reduction in personal exposure.

Frontier president Dempsey sells 300.0K shares at $8.81; reduces stake 38.0% to 490.4K shares

President James G. Dempsey sold 300,000 shares at $8.81 on 2025-02-14, reducing his holdings by 38.0% to 490,419 shares post-transaction. At Frontier (ULCC), Dempsey's prior three measurable sales occurred in August 2023 and November 2023, of which only one showed a negative 90-day return (the August 2023 sale fell -56.0%), indicating limited success in timing exits at this ticker. The current stock price of $8.82 sits 12.3% below the 52-week high of $10.06, while the company maintains solid fundamentals with $935.0M quarterly revenue and a P/E of 22.05. The timing pattern at ULCC shows only 1 of 3 prior measurable sells were well-timed at the 90-day mark, suggesting Dempsey's historical exits at this ticker have not consistently preceded declines.

CEO Barry Biffle sold 433,000 shares (26.1% of holdings) at $9.42 on Feb 7 as stock rallies +18.7% in 30 days

Barry Biffle, CEO of Frontier Group Holdings (ULCC), sold 433,000 shares on 2025-02-07 at $9.42, reducing his holdings from 1.66M to 1.22M shares. The sale occurs during a period of upward price momentum: the stock has gained 18.7% over the prior 30 days and 48.6% over 90 days, now trading at $9.73, just 3.3% below its 52-week high of $10.06. Biffle's cross-ticker track record shows a 100.00% well-timed rate across 14 prior open-market sales with an average 90-day return of -25.1%, indicating his historical sells have consistently preceded stock declines. However, at ULCC specifically, his 1 measurable historical sale (2024-03-06) posted a -33.7% 90-day return, which was well-timed, but recent same-ticker sales in January 2025 remain unmeasurable. The company posted positive net income of $26.0M on $935.0M quarterly revenue with 7.9% annual growth, though full-year net income was negative, creating a mixed fundamentals backdrop against the recent stock appreciation.

Then-CEO Biffle Barry sold 433,000 shares (433.0K shares) for $3,644,920.00 via scheduled 10b5-1 plan.

The transaction was executed under a pre-arranged 10b5-1 trading plan adopted on 2024-08-14, meaning this was a scheduled, not discretionary, sale. Post-transaction holdings of 1,216,817 shares represent a 26.2% reduction from pre-transaction holdings of 1,649,817 shares. As a scheduled trade under Rule 10b5-1, this sale carries no timing signal and reflects a predetermined liquidation schedule rather than a contemporaneous market judgment.
