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

Rhea-AI Filing Summary

Fluor Corporation and affiliates amended their Schedule 13D to report changes in holdings of NuScale Power Corporation Class A common stock. The filing shows the Reporting Persons collectively beneficially own 119,290,806 shares, representing 41.9% of the Class A shares outstanding on the stated record basis. Fluor Enterprises exchanged 15,000,000 Class B units for 15,000,000 Class A shares in August 2025 and began permitted sales of Class A shares on September 16, 2025 under an Exchange and Lock-Up Agreement. Those sales have reduced the Reporting Persons' percentage ownership and may continue as allowed by the agreement.

Insights

Securities Analyst

TL;DR Reporting Persons disclosed a material ownership transfer and commenced permitted stock sales, reducing their stake in NuScale.

The amendment documents a large in-kind exchange of 15,000,000 Class B units for Class A shares and confirms that Fluor Enterprises began selling Class A shares on September 16, 2025 in compliance with the Exchange and Lock-Up Agreement. The filing quantifies current beneficial ownership as 119,290,806 shares (41.9%). This is a clear disclosure of a substantial shareholder executing a planned liquidity event that reduces its ownership percentage.

Corporate Governance Expert

TL;DR Amendment provides transparent disclosure of ownership changes and ongoing permitted sales under a contractual lock-up framework.

The filing updates prior Schedule 13D information, specifying record ownership breakdowns: Fluor Enterprises holds 7,890,587 Class A shares and 110,936,472 Class B shares; NuScale Holdings holds 463,747 Class B shares. It references the Exchange and Lock-Up Agreement and notes sales are being conducted within its terms, which is important for governance and shareholder notice.

Item 4.	Purpose of Transaction
	This Amendment No. 3 on Schedule 13D/A (this "Amendment No. 3") 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").
