Sera Prognostics, Inc. (SERA) 鈥� Form 4 insider filing
On 7 July 2025, director Mansoor Raza Mirza reported the sale of 234 Class A common shares at $2.36 per share. The shares were automatically sold to cover federal and state tax-withholding obligations triggered by the vesting of previously granted restricted stock units ("RSUs"). The company鈥檚 tax-settlement policy requires a mandatory "sell-to-cover" transaction; therefore, the sale was not a discretionary disposition.
Following the transaction, Mirza鈥檚 direct beneficial ownership stands at 58,927 shares. No derivative securities transactions were reported, and there is no indication of additional open-market sales or purchases.
The size of the sale is immaterial relative to the insider鈥檚 remaining holdings, and because it was executed solely for tax purposes, the filing is neutral from a valuation or sentiment perspective.
Iron Mountain Incorporated (NYSE: IRM) filed a Form 4 on 8 July 2025 reporting insider activity by director Doyle R. Simons.
- Two acquisitions of derivative securities: 340.987 phantom shares on 3 July 2025 and 347.908 phantom shares on 7 July 2025, both coded 鈥淎鈥�.
- Plan-based transactions: The units were credited under the company鈥檚 Directors Deferred Compensation Plan; each phantom share mirrors one IRM common share and will be delivered after the director鈥檚 board service ends or upon disability.
- Post-transaction balance: Simons now holds 44,369.762 phantom shares, up by 688.895 units from the prior balance.
- Reference pricing: Column 8 lists weighted-average prices of $100.56 and $100.601, representing multiple trades executed between $100.419 and $100.624.
- Signal strength: Because the activity is compensation-related rather than open-market buying, the transactions are generally considered routine and carry limited market-moving impact.
Sera Prognostics Chief Commercial Officer Dyaarl Lee Anderson Jr. received significant equity compensation on June 23, 2025, consisting of two components:
- 67,114 Restricted Stock Units (RSUs) with a four-year vesting schedule: - 25% vests on June 10, 2026 - Remaining 75% vests quarterly over three years
- 102,534 Stock Options with strike price of $1.87: - 25% vests on June 10, 2026 - Remaining 75% vests monthly over three years
Both grants require continued service with the company. The equity awards suggest a long-term retention strategy for the Chief Commercial Officer position, with zero-cost RSUs balanced against performance-based stock options. The relatively low strike price of $1.87 indicates potential upside opportunity in the company's growth prospects.
