PTLO Portillo's Inc. Insider Trading

Director Eugene Lee buys 70K shares as PTLO trades well below 52-week highs; mixed timing history on prior purchases.

Eugene Lee, a Portillo's director, purchased a substantial stake of shares on the open market, marking his sixth open-market purchase in the past three years and his second buy in less than three months. The purchase occurred as the stock trades significantly below its 52-week high, a typical window for insider accumulation. However, Lee's track record at this ticker is mixed: his most recent prior purchase saw the stock rise modestly over the following month but decline sharply over the longer term, while an earlier purchase moved in the opposite direction with an initial decline followed by further losses. Portillo's itself remains profitable with steady revenue growth, though the latest quarter showed a slight loss, creating some operational uncertainty. This buy-in weakness is noteworthy, but Lee's conflicting returns on prior purchases at this stock—well-timed in the near term but poorly-timed over longer horizons—suggests caution about reading too much conviction into the timing alone.

Director Lee Eugene I Jr purchased 286,000 PTLO shares at $5.18; holdings now 416,250 shares (+219.6%)

Lee Eugene I Jr, a Director, purchased 286,000 shares at $5.18 on March 13, 2026, increasing his holdings from 130,250 to 416,250 shares—a 219.6% expansion. The purchase occurred at a price 62.0% below the 52-week high of $14.03, though the stock has declined 8.3% over the past 30 days. His prior buy at PTLO (August 2025) showed poor timing, with a -34.2% 90-day return, and his cross-ticker track record shows mixed results: 4 prior buys averaged -3.7% over 30 days and +4.4% over 90 days, with a 50% win rate. The company's fundamentals show modest growth (3.0% annual revenue growth) with a P/E of 23.17, and the insider's significant accumulation warrants attention to whether this reflects a contrarian positioning or other undisclosed factors driving the transaction.

CEO Michael Osanloo purchased 13,320 shares for $99,994.40 in 2 transactions (Aug 8–11); holdings up 25.6% to 65,317 shares as stock trades -49.0% from 52-week high.

CEO Michael Osanloo executed 2 separate purchases totaling 13,320 shares for $99,994.40 between August 8 and August 11, 2025, raising his holdings by 25.6% to 65,317 shares at a blended average price of $7.51. This open-market buying occurred while the stock trades at $7.85, down -49.0% from its 52-week high of $15.39 and down -31.6% over the past 30 days, signaling accumulation during a sustained decline. The timing is noteworthy: 3 other insiders also purchased within the past 14 days, forming a cluster buy pattern, though his prior 1 open-market sale at PTLO on 2024-08-09 was not well-timed at the 90-day mark (the stock rose 24.1% afterward). The company reported $188.5M in quarterly revenue with +4.5% annual growth and an 8.7M net income, yielding a P/E of 16.02 and market cap of $485.1M, providing a modest fundamental backdrop for evaluating the conviction or context behind this accumulation.

Director Lee Eugene I Jr bought 130,250 shares of PTLO at $7.68; stock down 51.8% from 52-week high amid 3-insider cluster buy.

Director Lee Eugene I Jr purchased 130,250 shares for $1,000,320.00 on 2025-08-07, establishing an initial position in PTLO. The purchase occurred as the stock trades at $7.42, down 35.1% over 30 days and 51.8% below its 52-week high of $15.39. A cluster pattern is present: 3 other insiders have also bought within the past 14 days, suggesting coordinated confidence at depressed price levels. Across his open-market history, Lee has completed 3 prior buys with a 66.67% 90-day win rate and average 90-day return of +17.3%, though those results span multiple tickers and are not predictive of PTLO performance specifically. The company's fundamentals remain modestly healthy: P/E of 15.14, net income of $8.7M on revenue of $188.5M, and annual revenue growth of +4.5%.

General Counsel Kaiser Kelly buys 27,000 PTLO shares at $7.68; 3 other insiders bought within 14 days as stock down 51.8% from 52-week high.

Kaiser Kelly M, General Counsel and Secretary, purchased 27,000 shares at $7.68 on 2025-08-07, increasing his holdings by 65.1% from 41,495 to 68,495 shares and investing $207,360.00 in the transaction. This purchase occurs amid a significant valuation decline: the stock trades at $7.42 today, down 51.8% from the 52-week high of $15.39 and down 35.1% over the past 30 days. The material significance is amplified by a cluster pattern in which 3 other insiders also bought within the past 14 days, indicating coordinated buying interest among the executive team. The fundamentals show a stable business—$188.5M quarterly revenue, $8.7M net income, and 4.5% annual revenue growth—yet the valuation compression may have triggered multiple executives to deploy capital simultaneously.

CFO Michelle Greig purchases 40,000 PTLO shares at $7.67 amid -51.8% decline from 52-week high; cluster pattern with 3 other insiders buying in past 14 days

CFO Michelle Greig acquired 40,000 shares (40.0K shares) for $306,800.00 at $7.67, increasing her holdings by 30.0% from 133,405 to 173,405 shares. The purchase occurs as PTLO trades at $7.42, representing -51.8% from its 52-week high of $15.39 and -35.1% over the past 30 days. This transaction is part of a broader cluster pattern: 3 other insiders also purchased shares within the same 14-day window. The synchronized buying by multiple executives despite severe recent price deterioration and a 34.0% 90-day decline suggests a collective assessment of valuation relative to fundamentals (Revenue $188.5M, Net income $8.7M, P/E 15.14). The 30.0% increase in the CFO's personal stake merits investor attention as a data point in assessing management's confidence levels during a period of significant drawdown.

Director Joshua Lutzker sold 10,000,000 shares of PTLO for $122,300,000 in 4 separate transactions at $12.23/share on 2025-05-19

Joshua Adam Lutzker, a Director at Portillo's Inc., executed 4 separate sales totaling 10,000,000 shares for $122,300,000 at a blended average price of $12.23 on 2025-05-19. This represents a reduction of 90.5% versus his pre-transaction holdings of 11,045,630 shares. The filing contains a derivative-conversion transaction; Lutzker's derivative holdings in Table II are not yet reflected in our database, so his post-transaction equity position of 1,045,630 shares may not represent his total beneficial interest. The scale of this multi-tranche sale and the substantial dollar value warrant investor attention to changes in insider holdings and any related Form 4 detail regarding the derivative conversion context.

Director Hartung Jack bought 72,500 shares of Portillo's (PTLO) at $12.82 on 2025-03-13 for $929,450.00; stock now trades at $12.32.

Director Jack Hartung purchased 72,500 shares of Portillo's on 2025-03-13 at $12.82, committing $929,450.00 to establish a new position. The stock currently trades at $12.32, representing a -3.9% decline from the transaction price, with the purchase occurring when the stock was trading 20.0% below its 52-week high of $15.39. Hartung's cross-ticker track record shows a single prior sale with strong net-negative 90-day returns (avg 90d return -98.3%, 90d well-timed rate 100.00%), though this backward-looking metric does not directly inform the current purchase's merit. The company posted $178.3M quarterly revenue with $7.2M net income and annual revenue growth of 4.5%, trading at a P/E of 25.67 with $761.3M market cap—a relatively mature restaurant operator showing moderate growth.

Portillo's CMO Scarpino sells 96,722 shares across 3 transactions for $1,136,099.27, reducing stake by 77.3%

Chief Marketing Officer Nicholas Anthony Scarpino executed 3 separate sales on 2024-08-15, offloading 96,722 shares for $1,136,099.27 at blended average price of $11.75, leaving him with 28,450 shares post-transaction. This represents a -77.3% reduction in his holdings. The sales occurred within the context of PTLO trading at a current price of $12.08, down -36.4% from its 52-week high of $19.00 but up +23.9% over the past 30 days and +16.7% over 90 days. The magnitude of the stake reduction—disposing of nearly four-fifths of his position—is material for a C-suite executive and merits investor attention, particularly given the company's recent price recovery trajectory and elevated valuation (P/E 35.53) despite solid fundamentals showing +15.8% annual revenue growth.

Portillo's CEO Osanloo Michael sold 66,052 shares (45.5% of holdings) at $10.29 on 2024-08-09 for $679,675.08.

CEO Michael Osanloo reduced his stake in Portillo's by 66,052 shares, cutting his holdings from 145,093 shares to 79,041 shares—a 45.5% reduction. The sale occurred at $10.29 per share when the stock was trading 44.0% below its 52-week high of $19.25, suggesting the transaction took place during a depressed valuation period. The company's fundamentals remain solid with latest-quarter revenue of $181,862,000.00 and annual growth of 15.8%, though the P/E of 31.71 reflects elevated valuation relative to earnings. A substantial sale by the CEO warrants investor attention to whether this reflects changed capital allocation priorities or portfolio decisions independent of company outlook.
