restricted stock units ("RSUs") financial
"The Reporting Person was granted restricted stock units ("RSUs"), which represent a contingent right"
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.

FAQ

What did MiNK Therapeutics (INKT) director John Bradley Holcomb report in this Form 4?

He reported two stock-based compensation grants. The transactions reflect restricted stock units converted into common shares for board and committee service, rather than open-market buying, and increase his direct holdings in MiNK Therapeutics to 3,458 shares after the reported awards.

How many MiNK Therapeutics shares did Holcomb acquire through these grants?

He acquired 1,091 shares on June 1, 2026, and 1,239 shares on March 2, 2026. Both awards were made as restricted stock units for board and committee retainers, bringing his total direct holdings to 3,458 shares after these compensation-related transactions.

Were Holcomb’s MiNK Therapeutics transactions open-market purchases or compensation grants?

They were compensation grants, not open-market purchases. The filing classifies both as “Grant, award, or other acquisition,” with footnotes explaining that restricted stock units were issued instead of cash retainers for board and committee service, vesting one month after each grant date.

What prices were used to value John Bradley Holcomb’s MiNK Therapeutics RSU grants?

The June 1, 2026 grant used a value of $12.38 per share for 1,091 shares. The March 2, 2026 grant used $10.90 per share for 1,239 shares. These prices reflect the per-share values recorded for the restricted stock unit awards.

Why does the MiNK Therapeutics Form 4 mention an administrative error for Q1 2026 RSUs?

A footnote states that RSUs for Q1 2026 board and committee compensation were not filed on time due to an administrative error. The March 2, 2026 grant of 1,239 shares is therefore being reported now to correct the prior omission in regulatory reporting.

How do the MiNK Therapeutics RSUs granted to Holcomb vest?

The restricted stock units each convert into one share of common stock. According to the footnote, the RSUs vest one month from the grant date, meaning the director earns the underlying shares after a short service-based vesting period following each grant.
