Bitfufu Inc. (NASDAQ:FUFU) furnished a Form 6-K on September 29, 2026, reporting that the Committee on Foreign Investment in the United States, known as CFIUS, has completed its review of the company's agreement to acquire a majority interest in an Oklahoma bitcoin mining facility. The filing says the committee determined there are no unresolved national security concerns, and that the parties then executed a national security agreement dated September 28, 2026.

The Underlying Acquisition

According to the filing, BitFuFu, through a wholly owned Delaware subsidiary, entered into a definitive agreement on February 19, 2025 to acquire 51 percent of the membership interests in Uni-Titan LLC. Uni-Titan operates a 51-megawatt bitcoin mining facility in Oklahoma. The clearance therefore comes more than nineteen months after the agreement was signed.

The 6-K does not disclose a purchase price. It also does not describe other closing conditions, and it does not say when the acquisition is expected to close. The filing is limited to the CFIUS outcome and the terms of the resulting national security agreement.

What CFIUS Decided

CFIUS is the interagency U.S. government committee that reviews certain transactions involving foreign investment for national security implications. In this case, the filing reports that on September 28, 2026 the committee completed its review and determined there were no unresolved national security concerns regarding the transaction. The filing does not describe the details of the review process or its length beyond the September 28 completion date, and it presents the clearance and the agreement as taking place on the same day.

That outcome came together with a national security agreement, which the filing describes as executed following the CFIUS clearance. The Department of Homeland Security and the Department of the Treasury act as the monitoring agencies under the agreement.

Conditions in the National Security Agreement

The filing summarizes several operating restrictions. The facility must be used solely for specified cryptocurrency mining business operations. The agreement restricts the deployment of advanced computing hardware at the site without prior written approval. Improvements to the facility require the non-objection of the monitoring agencies, and modifications to equipment require advance notification to the government.

According to the filing, the agreement remains in effect until the monitoring agencies provide written notice of termination. The 6-K does not state a fixed term.

These provisions set boundaries for how the site can be run after the acquisition, covering what the facility is used for, what hardware may be deployed and how changes are approved or notified.

The document is a short Form 6-K, the report that a foreign private issuer uses to furnish information to the SEC outside of its annual report. It lists no separate exhibits. It was signed on September 29, 2026 by Leo Lu, the company's Chairman and Chief Executive Officer. It contains no financial statements, no operating metrics for the mining site and no earnings information, so the effect of the acquisition on BitFuFu's hash rate, power capacity or results is not addressed.

Uni-Titan Closing and National Security Terms

The 6-K reports clearance but not completion. The filing gives no closing date or purchase price for the acquisition of the 51 percent interest in Uni-Titan LLC.

Under the national security agreement, obligations continue until the monitoring agencies give written termination notice.
