AI Insider Summary

The smallest detail that reveals James B. Breitmeyer's present strategy is a ticker that barely appears in the sell ledger: Vaxart (VXRT) shows 4 transactions with 0 buy and 0 sell shares — yet the entire recent 2026 Form 4 window is VXRT awards (16,610 and 8,315 shares on 2026-07-16; 157,400 and 78,800 on 2026-04-23). Zoom to the career totals across 168 filings and the distribution history lives elsewhere: Oncternal Therapeutics (64 filings; 175,000 buy vs 2,737,697 sell), Cadence Pharmaceuticals (68 filings; 0 buy / 127,500 sell), and Zogenix (23 filings; 0 buy / 86,625 sell). Otonomy and Applied Molecular Evolution are award-only stubs. The strategy today is new biotech board equity landing at VXRT; the multi-million-share sell total is an Oncternal-era legacy.

The smallest detail that reveals James B. Breitmeyer's present Form 4 posture is which issuer is active now.
