SANDELL SCOTT D

10% owner Sandell Scott D buys 207,100 shares of KRRO at $11.11 as 8 other insiders buy within 14 days; stock down 77.6% from $51.36 high.

A 10% shareholder purchased 207,100 shares for $2.3M, increasing holdings by 19.0%, concurrent with a cluster of 8 other insiders buying within the past 14 days. This coordinated activity occurs against a backdrop of significant share price deterioration: KRRO trades at $11.50, down 77.6% from its 52-week high of $51.36 and down 5.3% over the prior 30 days, despite a 39.7% 90-day gain. Fundamentally, the company reported $1.1M in quarterly revenue with $-18.1M in net income (unprofitable over the full fiscal year), though annual revenue growth is at +181.5%. The insider's prior trade at KRRO (a buy on 2024-04-22) yielded a 90-day return of -18.6%, and his cross-ticker buy history shows mixed outcomes: 4 prior open-market buys averaged +32.8% 30-day returns but only +2.9% 90-day returns with a 66.67% win rate. The clustering of purchases from multiple insiders amid depressed valuations and losses warrants investor attention to whether management views the recent decline as an opportunity or a signal of fundamentals turning."

10% Owner Scott D. Sandell buys 937,500 shares of SGP at $16.00 for $15.0M, bringing stake to 1,357,263 shares (+223.3%)

Scott D. Sandell, a 10% owner, purchased 937,500 shares at $16.00 on 2026-02-09, increasing his holding from 419,763 shares to 1,357,263 shares—a 223.3% increase in his pre-transaction position. This $15.0M transaction occurs within 4 trading days of the company's recent listing and coincides with 14 other insider purchases within the past 14 days, establishing a coordinated cluster buy pattern. The stock now trades at $27.55 (as of 2026-02-11), representing a 72.2% premium to Sandell's transaction price, though 52-week comparisons are not yet meaningful given the recent listing. This concentrated accumulation by a major shareholder alongside broad insider interest warrants investor attention, particularly given the structure of derivative holdings flagged in the filing that may not be fully captured in the reported post-transaction share count.

10% Owner SANDELL SCOTT D buys 500,000 MBX shares at $16.00 ($8.0M); 14 other insiders also bought in past 14 days

SANDELL SCOTT D, a 10% owner of MBX Biosciences, purchased 500,000 shares at $16.00 on 2024-09-16, increasing his position from 3,114,486 shares to 3,614,486 shares, a net increase of 16.1%. The transaction is notable for its scale—$8.0M in capital deployed—and occurs as part of a broader cluster pattern: 14 other insiders have also purchased within the past 14 days. This coordinated buying across multiple insiders within a concentrated time window on a very recently listed stock (3 trading days post-listing) reflects participation in the company's early public-market phase. The current stock price of $21.50 is materially higher than the $16.00 transaction price, though given the early trading window, relative valuation trends remain unclear. The filing should be reviewed for derivative securities in Table II, which may represent additional economic interests not yet reflected in the public database.
