Significance 4/10

Chief Concept Officer Jammet Nicolas buys 4,428 shares of Sweetgreen (SG) at $5.71; stock now $6.00, down -77.4% from 52-week high of $26.53.

Jammet Nicolas purchased 4,428 shares at $5.71 on 2026-03-05, increasing his holdings by 24.4% to 22,543 shares. The stock now trades at $6.00, a modest 5.1% premium to the transaction price but -77.4% below the 52-week high of $26.53. Reviewing his same-ticker history at SG, Nicolas has completed 5 prior trades: two buys in November 2025 achieved 30-day returns of +30.3% and +33.2%, while three sells in December 2024 preceded 90-day declines of -37.3%, -40.5%, and -39.0%, demonstrating 60% well-timed outcomes at this ticker. His cross-ticker track record shows 18 prior sells with an 83.33% well-timed rate (sales preceded declines), but only 2 prior buys with mixed results (avg 90d return -1.8% and 0% win rate). Against a backdrop of deteriorating fundamentals—the company is unprofitable with annual revenue growth of only +0.4% and a $-36.1M net loss in the latest quarter—this purchase follows earlier buying strength in November but occurs as the stock is severely depressed from its peak.

$99,804
Significance 5/10

CCO Nicolas Jammet buys 18,115 shares ($99.8K) at $5.51 avg; stock down 87.8% YTD, company unprofitable.

Nicolas Jammet, Chief Concept Officer, executed 2 open-market purchases totaling 18,115 shares for $99,803.75 at a blended average price of $5.51 on 2025-11-12, establishing a first position in SG shares. This acquisition occurs amid significant price deterioration: the stock trades at $5.37 (current price), down 87.8% from its 52-week high of $43.97 and down 28.5% over the past 30 days. The company reported revenue of $172,393,000.00 (latest quarter) with net income of $-36,146,000.00, reflecting ongoing unprofitability. Notably, Jammet's prior transactions at Sweetgreen (5 sells in December 2024) were well-timed at the 90-day mark, with all subsequent price declines ranging from 36.8% to 43.2% — a pattern that suggests this insider has demonstrated timing discipline at this specific ticker, though the current buy represents his first equity purchase at SG.

Significance 6/10

CCO Jammet Nicolas sells 170,199 shares of SG at $37.73 on 2024-12-13; stock down 20.1% from 52-week high; company unprofitable with $-20.8M net income.

Jammet Nicolas, Chief Concept Officer, sold 170,199 shares for $6,421,608.27 on 2024-12-13 at $37.73, reducing his position by 8.8% from 1,930,233 to 1,760,034 shares. The sale occurred when SG stock is down 20.1% from its 52-week high of $43.97, and the company remains unprofitable with net income of $-20.8M over its most recent full fiscal year, despite quarterly revenue of $173.4M and annual growth of 24.2%. Notably, this is the fourth sale by Nicolas in four days (sells on both 2024-12-09 and 2024-12-13), suggesting sustained portfolio adjustment rather than an isolated trade. His cross-ticker track record shows 19 prior sells with a 20.00% well-timed rate at the 90-day mark, but the timing utility of this specific transaction cannot yet be assessed given the stock's current proximity to the transaction price ($35.12 vs $37.73).

50,423 shares
$1,955,251
Significance 6/10

Chief Concept Officer Jammet Nicolas sells 50,423 shares for $1,955,250.87; holds zero shares post-transaction due to derivative conversion

Jammet Nicolas executed 6 separate sales totaling 50,423 shares for $1,955,250.87 at a blended average price of $38.78 on 2024-12-09. This filing contains a conversion of derivative securities (Table II, not yet populated in our database), meaning the insider's full position extends beyond the Table I shares shown here and the post-transaction zero shares should not be interpreted as a complete exit. The sales occurred near SG's 52-week high of $43.97, with the current price at $38.83 representing an 11.7% decline from peak. Nicolas has completed 5 prior sales at SG within recent days (2024-12-05, 2024-12-03, 2024-11-25), indicating a concentrated selling pattern; outcomes from these recent sales remain unmeasurable. His cross-ticker track record shows 13 prior sells with a 90-day well-timed rate of 33.33% and average 90-day return of +9.1%, suggesting his sales historically coincided with subsequent stock appreciation rather than declines.

$1,348,500
Significance 6/10

Chief Concept Officer Jammet Nicolas sold 33.6K shares (33,598) at $40.14 avg, exiting SG position entirely via derivative conversion

On 2024-12-05, Jammet Nicolas executed 2 separate sales totaling 33,598 shares for $1,348,499.57, eliminating his entire stake at a blended average price of $40.14. The stock now trades at $37.67, down 5.1% over the past 30 days despite a +24.2% 90-day gain. A critical context: this sale is part of a derivative-conversion transaction (Table II derivative securities), meaning the shares sold were converted from options or other derivative instruments rather than representing a liquidation of common equity holdings. Nicolas's cross-ticker track record shows 17 prior sells with a 90-day well-timed rate of 33.33%, suggesting modest predictive value; however, all 5 prior same-ticker trades at SG remain insufficient to assess timing accuracy at this specific stock. The company posted $173.4M revenue (up 24.2% annually) but remains unprofitable with $-20.8M net income, adding context to insider activity in a high-growth, pre-profitable business.

$1,624,613
Significance 5/10

Chief Concept Officer sells 41,999 shares for $1.6M at blended $38.68; retains 1.93M shares

Jammet Nicolas executed 2 separate sales totaling 41,999 shares for $1,624,613.01 on 2024-12-03, representing a -2.1% reduction in his pre-transaction holding of 1,972,232 shares. The blended average price of $38.68 is 3.4% below the current price of $40.05 and 11.9% below the 52-week high of $43.97. At Sweetgreen, Nicolas has completed 5 prior open-market sales (all at this single ticker), with outcomes for the 3 most recent still unmeasurable. His cross-ticker track record across 11 prior sells shows an average 90-day return of +9.1%, indicating that post-sell price movements have historically risen rather than fallen. The company is growing revenue at 24.2% year-over-year but remains unprofitable (full-year net income was negative $-20,816,000.00), setting this sale within a context of operational losses and continued reliance on top-line expansion.

$1,178,685
Significance 4/10

Chief Concept Officer Jammet Nicolas sold 26,193 shares at $45.00 for $1,178,685 at Sweetgreen (SG).

Jammet Nicolas executed 2 separate sales on 2024-11-25, selling 11,642 shares and 14,551 shares at $45.00 each for a combined $1,178,685, reducing his stake by 1.3% to 1,930,233 shares post-transaction. The sales occurred near the 52-week high of $43.97 and represent a modest reduction in holdings rather than a material position shift. Sweetgreen trades near current price of $42.43, down 3.5% from its 52-week high, while the company posted annual revenue growth of 24.2% but remains unprofitable with net income of -$20,816,000 in its most recent full fiscal year. His prior sales at this ticker show mixed timing outcomes, with only 1 of the measurable prior trades well-timed at the 90-day mark, offering limited predictive signal from this insider's historical pattern at SG.

Significance 4/10

Chief Concept Officer Jammet Nicolas sells 37,688 shares (37.7K) at $40.04; retains 1,930,233 shares post-transaction

Jammet Nicolas executed 2 separate sales totaling 37,688 shares for $1,509,027.52 on 2024-11-06, reducing his stake by 1.9% to 1,930,233 shares. The stock is trading at $42.20 (current price), up 10.5% over 30 days and 20.5% over 90 days, at the 52-week high. His prior trades at Sweetgreen show mixed timing outcomes: 1 of 2 measurable 90-day results were well-timed (the June 2024 sale), while cross-ticker performance indicates a 50% well-timed rate across 5 prior sells averaging 1.4% 30-day and 3.0% 90-day returns. The company is unprofitable (net income $-14.5M in the latest quarter) but growing revenue at 24.2% year-over-year on a $4.1B market cap. This is a discretionary open-market transaction of a retained executive position, not a scheduled trade plan or derivative conversion.

Significance 6/10

Chief Concept Officer Jammet Nicolas sold 38,295 shares at $35.10 on 2024-09-13 for $1,344,154.50 at Sweetgreen (SG)

Jammet Nicolas sold 38,295 shares through two separate transactions totaling $1,344,154.50 at a blended average price of $35.10, reducing his holdings by 1.9% to 1,930,233 shares. This is a material transaction representing nearly $1.3M in equity disposition. The sale occurred at $35.10, above the current price of $33.74 but reflecting broader price weakness—the stock is down 9.7% over 30 days and 10.4% from its 52-week high of $37.65. In the context of Sweetgreen's fundamentals, the company remains unprofitable with net income of -$14,460,000.00 over its most recent full fiscal year, though it has achieved 24.2% annual revenue growth. The insider's prior sales at this ticker show mixed timing outcomes: a June 2024 sale preceded a 90-day decline of 4.0%, while a May 2024 sale preceded a 90-day gain of 10.1%, reflecting inconsistent predictive signal at this specific ticker. This filing contains a derivative-conversion component per the FLAG, meaning the Table I shares_after figure does not represent the insider's complete position in the company.

Sell
169,767 shares
$6,072,566
Significance 6/10

CCO Jammet Nicolas sold 169,767 shares of SG at $35.77 on 2024-08-26 for $6.1M, reducing stake by 8.1% while stock has risen 34.8% in 30 days.

Jammet Nicolas, Chief Concept Officer, executed a $6,072,565.59 sale of 169,767 shares at $35.77 on 2024-08-26, reducing his holdings from 2,100,000 to 1,930,233 shares. The transaction occurred near the stock's 52-week high of $37.65, just before a 34.8% surge in the subsequent 30 days—the stock is currently at $34.59, suggesting the insider sold shortly before a near-term peak. His prior two sales at Sweetgreen (2024-06-05 and 2024-05-15) showed mixed 30-day outcomes (-9.6% and +0.8%), with only one measurable 90-day outcome (+10.1% on the May sale), indicating no consistent pattern of well-timed exits at this ticker. The company remains unprofitable with annual net income of $-14,460,000.00 despite 24.2% revenue growth, leaving the strategic rationale for this large equity reduction ambiguous alongside the post-sale price momentum.
