Novack David F

Novack David F., President and COO of Dynavax Technologies (DVAX), has filed 44 Form 4 transactions over the past year, with a pronounced sell-side bias. Across all filings, open-market sales totaled roughly $3.18 million, while open-market purchases were zero. The only acquisition value on record, about $11,400, came from option exercises and equity awards—compensation mechanics rather than conviction buying. The most recent cluster of filings, dated February 10, 2026, consists entirely of code "D" dispositions (sales back to the issuer) and code "A" grants, with no cash changing hands, reinforcing that the insider is not adding shares at market prices. The largest single transaction occurred on January 15, 2026, when Novack sold DVAX shares worth approximately $1.78 million, paired with option exercises valued at $984,180 and $136,100. That sale dwarfed a December 24, 2025 disposition of $464,700, which was accompanied by tax-withholding shares (code "F") worth $739,885.66 and two option exercises. Earlier in 2025, he executed smaller sales of $140,000 on March 24 and $190,391.60 on March 18, both following option exercises. The pattern is consistent: Novack exercises options and immediately sells a portion of the resulting shares, with no open-market buys in the trailing period. The four most recent sell-code transactions, all dated January 15, 2026, total $1.78 million, indicating an acceleration in realized value over the prior quarter’s activity.
