Cfius Filing: Mandatory Requirements and Voluntary Filing Options

Control depends on the power to determine important business matters, not majority ownership alone. Contractual and governance rights can therefore bring a transaction within CFIUS jurisdiction.

Certain noncontrolling investments also qualify when they involve a TID U.S. .usiness, meaning a business involving specified critical technologies, critical infrastructure, or sensitive personal data. Relevant rights include:

• Access to material nonpublic technical information.
• Board membership, observer rights, or nomination rights.
• Involvement in substantive decisions concerning covered technology, infrastructure, or data.

An asset acquisition may qualify if the assets constitute a U.S. .usiness. Certain joint ventures also qualify when a U.S. .usiness contributes existing operations and a foreign participant obtains relevant rights.

For asset purchase transactions, what transfers matters more than the deal’s title. Part 802 separately covers certain real estate transactions.

This pathway generally examines whether the business produces, designs, tests, manufactures, fabricates, or develops qualifying technology. It then asks whether exporting that technology to specified foreign transaction parties or owners would require a U.S. .egulatory authorization.

An actual export need not be planned. Classification under the Export Administration Regulations or other applicable regimes can change the result. Only specified exceptions affect this analysis; an export license exception does not automatically eliminate the filing obligation.

The second pathway generally concerns a foreign person acquiring a substantial interest in a TID U.S. .usiness while a foreign government holds a substantial interest in that investor.

The basic voting-interest thresholds are 25% or more in the U.S. .usiness and 49% or more in the foreign investor. Indirect ownership, investment-fund provisions, and exceptions require further analysis. Falling below these figures does not exclude other CFIUS jurisdiction or filing pathways.

Parties generally must submit the required declaration, or a notice instead, at least 30 days before completion. Specified written CFIUS responses can permit earlier completion.

The completion date generally follows the earliest ownership transfer. Moving equity first while delaying voting or board rights does not necessarily postpone the filing deadline.

CFIUS must conclude action on the transaction before parties obtain the corresponding protection against later review. Exceptions include material misstatements or omissions and certain mitigation violations.

Clearance also does not replace other regulatory approvals. A CFIUS compliance assessment should distinguish filing, clearance, and continuing obligations.

Failure to submit a mandatory filing on time can carry civil penalties up to the greater of $5 million or the transaction value per violation. CFIUS assesses the circumstances rather than automatically imposing the maximum. A late filing does not erase the earlier failure.

A declaration may save preparation time, but a subsequent notice request can lengthen the overall process. Complex ownership, sensitive technology, or government relationships may favor starting with a notice.

Filings should address ownership chains, government interests, investor rights, technology classifications, sensitive data, and transaction documents. Parties submit through the CFIUS Case Management System with required certifications.

Incomplete or inconsistent information can delay acceptance. Parties must also report material changes during the process.

An accepted notice enters a review of up to 45 days, followed when necessary by an investigation of up to 45 days. Extraordinary circumstances can permit one additional 15-day investigation extension. Presidential referral carries a separate 15-day decision period.

These periods are not a guaranteed total from first submission to clearance. Applicable rules also address deadlines falling on nonbusiness days.

Withdrawal requires CFIUS approval and may carry conditions. Refiling can begin another review cycle.

For rejected or withdrawn mandatory filings, § 800.401 generally prohibits completion earlier than 30 days after resubmission unless the Staff Chairperson gives written approval.

CFIUS does not issue advisory opinions on jurisdiction or mandatory filing obligations. Staff feedback is nonbinding and does not replace a required submission.

No. Excepted-investor status requires specified regulatory criteria. Nationality alone is insufficient, and qualifying status does not exempt every transaction.

No. It provides no safe harbor. Although § 800.401 permits completion after the specified written response for mandatory filing purposes, CFIUS can review the transaction later.
