Semiconductor M&A, Repriced.

Cross-border deal structure in the post-CHIPS Act era — what inbound and outbound parties must resolve before signing.

The CHIPS and Science Act of 2022 has propagated downstream effects through semiconductor M&A that have continued to develop through successive Commerce Department guidance, Treasury rule-making, and Executive Order activity into 2026. The cross-border deal structure that worked in 2021 does not work today. The brief below sets out what is structurally different — and the three practical implications for inbound acquirers, outbound divestors, and the sponsors holding semiconductor assets in their portfolios.

The argument is direct. The CHIPS Act and its administrative successors have changed three things about semiconductor M&A: the CFIUS lens applied to semiconductor transactions, the export-control and outbound-investment overlay on the deal structure, and the funding-recipient compliance perimeter that attaches to companies that received or applied for CHIPS funding. Any one of these would change the deal calculus; the combination has changed it materially.

What the CHIPS Act Did, in Operational Terms.

The CHIPS and Science Act authorized federal investment in U.S. semiconductor manufacturing capacity through direct funding, tax credits (notably the Section 48D Advanced Manufacturing Investment Credit), and adjacent research and workforce funding. The Commerce Department's CHIPS Program Office has allocated funding through 2025–2026 across leading-edge logic, memory, mature-node, and packaging facilities.

Sources: CHIPS and Science Act of 2022 (Public Law 117-167); Commerce Department CHIPS Program Office public guidance; Section 48D Treasury and IRS guidance. Specific funding allocations and award terms vary by recipient.

Three operational effects on M&A:

• The "Guardrails" condition. Recipients of CHIPS funding are subject to restrictions on certain transactions and certain operations in defined "foreign countries of concern" for ten years following the funding award. The restrictions cover material expansion of semiconductor manufacturing capacity in those countries, certain joint research and licensing activities with covered entities, and related conduct.
• Recapture provisions. Material non-compliance with the Guardrails — and with other funding-recipient conditions — can trigger recapture of funding, including amounts previously disbursed. The recapture risk attaches to the recipient entity and follows it through acquisitions, asset sales, and corporate restructurings.
• Information-sharing and pre-approval obligations. Funding recipients carry ongoing reporting and pre-approval obligations on certain corporate transactions. The buyer of a CHIPS recipient inherits these obligations; the seller of one carries them as a structural feature of the transaction.

The CFIUS Lens on Semiconductor Transactions.

CFIUS jurisdiction over semiconductor transactions has tightened independently of, but reinforced by, the CHIPS Act framework. Semiconductors appear prominently on critical-technology and emerging-technology lists. Investments in U.S. businesses that produce, design, test, manufacture, fabricate, or develop semiconductors at advanced nodes — and certain mature-node operations — fall within mandatory and voluntary CFIUS filing scope. Investments from "countries of concern" in any such business face presumptive scrutiny.

The practical effect on cross-border semiconductor M&A is that essentially every transaction involving a U.S. semiconductor target and a non-U.S. acquirer triggers a CFIUS analysis at minimum — and frequently triggers a mandatory filing. The window in which a semiconductor transaction could close without CFIUS engagement has effectively closed.

The Outbound-Investment Overlay.

Beyond CFIUS, the Outbound Investment Security Program — established through Executive Order in 2023 and developed through subsequent Treasury rulemaking — applies to certain U.S. investments in covered foreign-country businesses operating in semiconductors and microelectronics (alongside quantum and AI). The program creates a notification and, in some cases, a prohibition regime for outbound U.S. investment in defined activities in defined countries.

Sources: Executive Order 14105 (2023); subsequent Treasury Department final rulemaking. Specific covered activities, notification triggers, and prohibitions should be confirmed against current regulatory text.

For U.S. acquirers contemplating investment in covered foreign semiconductor businesses, the outbound-investment overlay creates an additional analytical layer parallel to (and separate from) traditional export-control analysis. The transactions affected are typically minority investments, joint ventures, and certain greenfield activities — situations that historically did not trigger national-security review on the outbound side.

Export controls under the Commerce Department's Entity List, the EAR, and the Foreign Direct Product Rule have continued to expand the scope of semiconductor-related technologies, equipment, and end-uses subject to license requirements — particularly with respect to advanced compute, AI training infrastructure, and advanced fabrication equipment. The export-control analysis is therefore part of the standing diligence on every cross-border semiconductor transaction.

Three Practical Implications for the Deal.

Implication 1. Diligence happens before LOI.

The pre-LOI diligence package on a cross-border semiconductor transaction now includes a CFIUS jurisdictional read, an outbound-investment-program analysis (if the acquirer is U.S. and the target is in a covered country), an export-control read on the target's products and processes, and — if the target has received CHIPS funding — a Guardrails-and-recapture analysis. None of this fits in the post-LOI confirmatory diligence period.

Implication 2. Structure responds to the regulatory perimeter.

The deal structure that works under the post-CHIPS framework is materially different from the structure that worked in 2021. Holding-company architecture, IP-licensing flows, employment-and-knowledge-transfer provisions, and post-close governance terms all carry new constraints. The structure is designed to survive review on the merits — not to minimize the deal's apparent regulatory footprint.

Implication 3. Timing widens.

The realistic signing-to-closing window on a cross-border semiconductor transaction has materially extended. CFIUS review, parallel foreign-direct-investment screens in the acquirer's home jurisdiction, export-control licensing, and (where applicable) CHIPS-recipient pre-approval all run on independent timelines that frequently overlap rather than nest cleanly. Six-to-nine-month signing-to-closing windows are now common where four months would have been the prior baseline.

What This Means by Party.

For non-U.S. acquirers of U.S. semiconductor businesses. The CFIUS analysis is the gating workstream. Begin it before the LOI, structure the transaction to survive review on the merits, and prepare to negotiate mitigation that is consistent with the underwriting case. The transaction's value is in the structure that holds, not in the headline price.

For U.S. acquirers of non-U.S. semiconductor businesses. The outbound-investment overlay and export-control analysis are mandatory diligence items. Targets in covered countries face the additional analytical layer; targets in allied jurisdictions face the lighter analysis but not zero. The structure that worked in 2020 will not pass diligence today.

For sellers of CHIPS-funded businesses. The Guardrails and recapture provisions follow the business. The transaction structure must preserve the funding without triggering recapture and must allocate the ongoing compliance burden in the purchase agreement. Buyer indemnities, escrow, and representation packages have all evolved.

For sponsors holding semiconductor portfolio companies. Exit-planning conversations begin earlier than in non-semiconductor sectors. The realistic universe of credible cross-border buyers has narrowed; the diligence requirements on all bidders have widened; and the timing risk on any specific buyer has increased. Selling well requires running the process to the buyer set that can actually close.

Semiconductor M&A in 2026 is not a domestic exercise with a foreign acquirer. It is a multi-jurisdiction regulatory process with a commercial transaction inside it. The firm runs the commercial side in coordination with named legal counsel on each regulatory surface — and the conversation begins before the LOI.
