Ambiq Micro CTO Hanson McLean Receives 80,308 RSUs
What Happened
Hanson Scott McLean, Chief Technology Officer and Director of Ambiq Micro, was granted 80,308 restricted stock units (RSUs) on March 6, 2026. The reported acquisition price is $0.00 (an equity award, not a market purchase). This Form 4 was amended and filed on April 2, 2026 to correct an administrative error affecting the RSU vesting commencement date.
Key Details
- Transaction type: Award/Grant (Form 4 code A) of 80,308 RSUs on 2026-03-06; reported 2026-04-02 (amended filing).
- Reported acquisition price: $0.00 (RSU grant).
- Vesting (per footnote): Each RSU converts to one share on settlement. 25% of the RSUs vest on October 1, 2027; thereafter 1/12 of the shares subject to the RSU vest quarterly, subject to continuous service under the 2025 Equity Incentive Plan.
- Shares owned after the transaction: Not specified in the provided filing details.
- Amendment note: Filing amended solely to correct the vesting commencement date (administrative correction).
Context
RSU grants are compensation awards and do not represent open-market purchases or sales; they vest over time and convert to shares upon settlement, so they are not an immediate liquidity event. The amendment means the company corrected the vesting start date in the public filing; it does not change the fact of the grant itself.
