[SCHEDULE 13D/A] NUSCALE POWER Corp SEC Filing

Rhea-AI Filing Summary

Fluor Corporation and affiliates amended their Schedule 13D to report changes in ownership of NuScale Power Corporation Class A common stock following permitted sales. Fluor Enterprises exchanged 15,000,000 Class B units for 15,000,000 Class A shares under an Exchange and Lock-Up Agreement and, after the initial lock-up expired, began selling those shares on September 16, 2025. The filing states Fluor Enterprises completed the sale of all 15,000,000 shares on October 8, 2025, reducing the Reporting Persons' percentage ownership of the issuer.

The Schedule shows aggregate shared voting and dispositive power of 111,400,219 shares for Fluor and Fluor Enterprises, equating to 39.1% of the combined outstanding Class A and Class B common stock base referenced. Fluor Enterprises separately holds 110,936,472 Class B shares (reported as 38.9% of outstanding) and NuScale Holdings holds 463,747 Class B shares (0.2%). The amendment updates Items 4 and 5 to reflect the exchange, the permitted sales and the resulting decline in beneficial ownership.

Positive

• Permitted sale completed: Fluor Enterprises sold all 15,000,000 exchanged Class A shares in compliance with the Exchange and Lock-Up Agreement
• Disclosure transparency: Reporting Persons updated Schedule 13D/A and Item 5 to reflect ownership and sales, showing adherence to SEC reporting rules

Negative

• Reduced ownership stake: Reporting Persons' aggregate beneficial ownership declined to 39.1%, lowering their relative voting influence
• Concentration shift: Sale of the exchanged shares may change investor perceptions of strategic commitment and could affect governance dynamics

Insights

Corporate Governance Expert

TL;DR: A major holder executed permitted sales that materially lowered its stake, altering voting dynamics.

The transaction mechanism began with an exchange of 15,000,000 Class B units for Class A shares under a documented Exchange and Lock-Up Agreement and concluded with the sale of those shares on October 8, 2025. Those sales were conducted within the agreement's permitted windows and daily volume limits, which the filing explicitly references.

The change reduces the Reporting Persons' combined beneficial ownership to 39.1%, which may affect control influence and shareholder voting power where previously higher holdings existed. Watch for any subsequent filings that disclose further sales, changes in shared voting arrangements, or amendments to lock-up terms within the next several weeks as holders finalize dispositions.

	This Amendment No. 5 on Schedule 13D/A (this "Amendment No. 5") is being filed jointly by (i) Fluor Corporation, a Delaware corporation and a publicly listed company on the New York Stock Exchange ("Fluor"), (ii) Fluor Enterprises, Inc., a California corporation ("Fluor Enterprises") and wholly owned subsidiary of Fluor, and (iii) NuScale Holdings Corp., an Oregon corporation ("NuScale Holdings", together with Fluor Enterprises and Fluor, the "Reporting Persons").
