Alpha Teknova, Inc. (TKNO) – Form 4 insider transaction
Director Martha J. Demski reported a single open-market sale of the company’s common stock on 27 June 2025. The transaction was executed under a Rule 10b5-1 trading plan adopted 12 March 2025 and was expressly intended to cover tax obligations arising from the vesting of director restricted stock units.
- Securities sold: 8,000 common shares
- Sale price: $5.064 per share
- Gross proceeds: approximately $40,512
- Post-transaction ownership: 12,000 common shares held directly
No derivative securities were acquired or disposed of, and no other transactions were reported. After the sale, Demski retains a direct equity interest in the company, but her share count declined by 40% from 20,000 to 12,000 shares. Because the disposition was pre-programmed under a 10b5-1 plan and earmarked for tax withholding, it is generally viewed as administrative rather than indicative of a changed outlook. Nevertheless, investors often monitor insider sales—especially by board members—for potential signaling effects. The filing does not disclose any changes to Demski’s role, company strategy, or financial performance.
