Makhzoumi Mohamad

10% owner Makhzoumi bought 207,100 shares of KRRO at $11.11 on 2026-03-10; stock now -77.6% from 52-week high; cluster buy by 8 others in 14 days

Makhzoumi Mohamad, a 10% owner, purchased 207,100 shares for $2,300,881.00, increasing his stake by 19.0% to 1.30M shares. This buy occurs within a broader cluster pattern: 8 other insiders also bought within the past 14 days, suggesting coordinated or simultaneous insider interest. However, context tempers conviction signals: the stock trades at -77.6% from its 52-week high of $51.36, and Makhzoumi's sole prior buy at KRRO (2024-04-22) returned -18.6% over 90 days. The company remains unprofitable with a $-18.1M net loss in the latest quarter, though revenue grew 181.5% year-over-year. The clustering pattern and large absolute purchase warrant monitoring, but the steep valuation decline and Makhzoumi's poor prior timing at this ticker suggest investors should scrutinize both the fundamental recovery thesis and whether the cluster reflects informed conviction or reactive buying into a depressed price.

10% Owner Makhzoumi Mohamad buys 937,500 shares ($15.0M) at $16.00; cluster of 14 other insiders bought within 14 days

Makhzoumi Mohamad, a 10% owner, purchased 937,500 shares for $15,000,000.00 at $16.00 on 2026-02-09, increasing his position from 419,763 shares to 1,357,263 shares (a +223.3% net increase). This transaction involves a derivative conversion and represents a substantial capital commitment by a significant shareholder. The filing reveals a cluster pattern: 14 other insiders also bought within the past 14 days, indicating coordinated insider accumulation at a recent IPO (4 trading days post-listing). The synchronized buying across multiple insiders during the stock's early public trading period is noteworthy, though the stock's limited public history means longer-term price context is not yet available.

10% owner Makhzoumi buys 500,000 MBX shares at $16.00 ($8.0M); 14 insiders also bought in 14 days

Makhzoumi Mohamad, a 10% owner, purchased 500,000 shares at $16.00 on 2024-09-16, expanding his holding to 3,614,486 shares post-transaction. The purchase occurs just 3 trading days after MBX's recent listing, and coincides with a broader cluster of insider buying activity: 14 other insiders purchased shares within the past 14 days. This coordinated acquisition pattern suggests institutional confidence at the early post-listing stage, though the stock has already moved 34.4% above the transaction price ($16.00 to $21.50 current). The transaction represents a substantial $8.0M commitment by a major shareholder during a period of concentrated insider accumulation.
