Wu Xiaobin

Insider trading profile for Wu Xiaobin at BeOne Medicines Ltd (ONC, formerly BeiGene) -- 189 transactions since 2018-04-30 through 2026-06-11. 383,896 shares sold, zero discretionary acquisitions. The company has undergone a name/symbol change (BGNE → ONC / BeOne Medicines). Transaction pattern: M-code (derivative vesting) events dominate: 2025-08-14 (119,340 + 399,828 = 519,168 shares) -- massive vesting batch. A-code (acquisition) events: 2026-06-11 (229,775 + 118,625 = 348,400 shares at $20.81 -- this is a large RSU/option exercise at deeply discounted price relative to current $261-$270 market); 2026-03-06 (78,624 + 168,922 = 247,546 shares). S-code (open-market sell) events are small but consistent: 2026-06-11 (626 at $261.20), 2026-06-08 (40 + 1,444 = 1,484 at $269-$270), 2025-11-17/12 (4,031 shares at $350-$382 range), 2025-11-12/13 (13,861 shares at $351-$381), 2025-08-14 (600 + 4,917 + 12,232 = 17,749 at $306-$308). Key observation: The 2025-08-14 M-code vesting of 519,168 shares was accompanied by only 17,749 in S-code sells -- the vast majority appears to have been withheld for taxes or retained. The 2026-06-11 A-code exercise of 348,400 shares at $20.81 (vs $261 market) is deeply in-the-money -- this represents significant insider economic exposure being established at what is likely a very low exercise price. However, the S-code sells (626 + 1,484 shares at $261-$270) show the insider is starting to liquidate some portion. The ONC stock has run from ~$20 exercise price to $350-$382 range -- a massive gain. The insider's pattern is heavily M-code/A-code (exercises/vesting) with only small S-code liquidation. Bearish overall: despite the large A-code exercises (which show holdings are being built up), the 189-transaction all-sell history across 8 years is undeniable. The fact that the company has been named BeiGene (ONC) through multiple name changes and this insider has been consistently selling throughout is a structural signal. The recent A-code at $20.81 may represent the final vesting wave before the insider fully exits. The sells at $261-$382 in 2026 show the insider is not waiting for higher prices -- they are taking profits as shares vest.
