WALTERS DIANA J 4

What Happened
Diana J. Walters, a director of NuScale Power (SMR), received an award of 8,681 restricted stock units (RSUs) on May 29, 2026. The grant is reported as an acquisition (code A) at $0.00 per unit (total reported value $0), as these RSUs are a form of compensation rather than a cash purchase.

Key Details

• Transaction date: May 29, 2026; Form 4 filed June 2, 2026 (timely — within the two-business-day reporting window).
• Award: 8,681 restricted stock units (RSUs) reported at $0.00 per unit.
• Vesting: RSUs vest quarterly in four equal installments over one year; first vesting on August 29, 2026.
• Deferral: Under the issuer’s Deferred Compensation Plan for Non-Employee Directors, Walters elected to defer receipt of underlying Class A shares upon vesting; she will instead receive an equal number of phantom shares. Each phantom share entitles her to one Class A share upon her separation from service.
• Shares owned after transaction: not specified in the filing.

Context
RSU awards are compensation and not an open-market purchase or sale; they don’t directly signal an immediate buy or sell. Because Walters elected to defer vested shares into phantom stock, she will not receive actual shares at each vesting date but will be entitled to equivalent shares only upon leaving the company.
