Key Details

• Transaction date: 2026-05-19; Form 4 filed: 2026-05-21 (timely filing).
• Transaction type/code: Award/Grant (A).
• Shares/units granted: 56,222 RSUs; reported acquisition price: $0.00 (RSUs, not an open-market purchase).
• Shares owned after transaction: Not disclosed on the Form 4.
• Footnote: RSUs vest 1/12 on the first Quarterly Date after the vesting commencement date (May 31, 2026), then 1/12 on each Quarterly Date thereafter (Quarterly Dates = Feb 28, May 31, Aug 31, Nov 30). Vesting is subject to continuous service per the company’s equity plan.

Context

• RSUs are a grant of future shares that only convert to common stock when they vest and are settled; they are not an immediate cash investment or sale. This award vests in 12 quarterly installments (over roughly three years) subject to continued employment, so it’s a retention/compensation grant rather than an immediate market signal.
