[Form 4] QT Imaging Holdings, Inc. Common Stock Insider Trading Activity

Rhea-AI Filing Summary

QT Imaging Holdings, Inc. reporting person Dr. Raluca Dinu, who serves as Chief Executive Officer and a director, was granted 25,000 stock options on 08/11/2025. The options have an exercise price of $1.90 and a stated expiration date of 08/11/2035, and are reported as directly owned following the grant.

The grant vests over roughly three years: one-third vests on August 15, 2026, and the remaining two-thirds vest in eight equal quarterly installments on each November 15, February 15, May 15 and August 15, with full vesting on August 15, 2028, subject to continued service. The award ties management compensation to future equity performance and would create dilution if exercised.

Positive

• Management alignment: Grant ties CEO compensation to future equity performance through time‑vested options.
• Retention focus: Multi‑year vesting schedule supports executive retention through August 15, 2028.

Negative

• Potential dilution: Exercise of the options would increase outstanding shares by 25,000, diluting existing holders.
• Time‑based vesting only: The award is structured on service milestones rather than explicit performance conditions.

Insights

Corporate Governance Expert

TL;DR: A routine time‑based option grant to the CEO aligns incentives but is largely a standard compensation action with limited immediate market impact.

The filing discloses a direct award of 25,000 options to the CEO with a $1.90 exercise price and a 10‑year contractual term. Vesting is purely time‑based, with clear milestone dates and full vesting in 2028 subject to continued service. From a governance perspective, the grant is conventional: it fosters retention and alignment with shareholders but contains no disclosed performance conditions that would explicitly tie payout to company metrics.

Executive Compensation Analyst

TL;DR: The award is a standard long‑term incentive: modest absolute size, multi‑year vesting, and potential dilution when exercised.

The option grant of 25,000 shares at $1.90 with time‑based vesting over three years is consistent with retention and long‑term incentive practices. The exercise price and 10‑year term give the holder extended optionality. Materiality for investors depends on the company’s share count, which is not provided; on its face, this appears to be a routine, non‑accelerating equity award rather than a transformational transaction.
