Insights

Equity compensation analyst

Routine director RSU grant that increases equity alignment without cash trading.

Director Deborah A. Grant received 20,361 restricted stock units of SOUNDTHINKING, INC. as compensation, recorded at a zero transaction price. This is a non-market grant, not an open-market purchase or sale, and reflects standard board equity incentives.

The RSUs vest on the earlier of June 3, 2027 or the next annual stockholder meeting, and may vest sooner if specific change in control conditions occur. If her continuous service ends before those triggers, the unvested RSUs terminate. This structure ties value to tenure and corporate events.

Following the grant, Grant holds 49,001 common shares directly, so the award meaningfully increases her stake relative to her prior holdings. Because no shares were sold and there is no trading plan reference, the filing mainly documents compensation-related equity, with limited signaling value for near-term market sentiment.

3 terms

Restricted Stock Units ("RSUs") financial

"Represents Restricted Stock Units ("RSUs"). All of the RSUs subject to this Award will vest upon the earlier of June 3, 2027..."

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

Change in Control financial

"In addition, all such RSUs will vest upon a Change in Control (as defined in the Plan)..."

A "change in control" occurs when the ownership or management of a company shifts significantly, such as through a merger, acquisition, or sale of a large part of its assets. This change can impact how the company is run and may influence its future direction. For investors, it matters because it can affect the company's stability, strategy, and value, often signaling potential changes in investment risk or opportunity.

Continuous Service financial

"Notwithstanding the foregoing, vesting shall terminate upon the Participant's termination of Continuous Service."
