The Compliance Shift Reshaping Deal Diligence
Renewable energy mergers and acquisitions in 2026 are being shaped by a single theme: compliance. According to FTI Consulting's 2025 M&A Year in Review, the outlook for renewables deal activity this year can be summarized in one word: compliance-driven.
That shift has direct consequences for finance teams, tax equity investors, lenders, and deal counsel working on clean energy transactions. Foreign Entity of Concern (FEOC) exposure is no longer a secondary diligence item. It is a primary credit risk.
What Is FEOC, and Why Does It Matter in M&A?
The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, introduced strict supply chain sourcing mandates as a condition of tax credit eligibility for clean energy projects. At the center of those mandates is the FEOC requirement.
A Foreign Entity of Concern is any company with material ties to a country designated as a national security concern, primarily China, Russia, Iran, and North Korea. Under the OBBBA, clean energy projects that use components traceable to a Prohibited Foreign Entity (PFE) lose eligibility for the Investment Tax Credit (ITC) and Production Tax Credit (PTC).
The FEOC rules apply to facilities beginning construction after December 31, 2025. The material assistance rule specifically applies to tax years beginning after enactment for those facilities. Projects that began construction on or before December 31, 2025, are exempt from the material assistance prong of the FEOC restrictions. However, all projects may be subject to the ownership and effective control tests beginning in the first taxable year after OBBBA enactment, regardless of construction start date.
The critical point for deal teams: Safe Harbor status does not fully insulate a project from FEOC exposure. A Beginning of Construction (BOC) date established before January 1, 2026 exempts a project from the material assistance test, but the ownership and effective control tests apply regardless of construction start date. A validly Safe Harbored project can still lose its tax credits if the taxpayer fails either of those tests.
How FEOC Exposure Affects Transaction Outcomes
FEOC risk now shows up directly in deal diligence, and it is affecting how transactions are structured and priced.
Platforms with clean, auditable supply chains hold a clear deal advantage and have a cleaner path to close. Tax equity investors and lenders require documentation that demonstrates non-FEOC sourcing across all three FEOC tests: Ownership, Effective Control, and Material Assistance. Without that documentation, the credit cannot be underwritten with confidence.
Platforms that cannot demonstrate FEOC compliance face material consequences. These include:
- Valuation discounts applied to assets with unresolved supply chain exposure
- Divestitures of assets with tainted equipment inventories
- Recapitalization requirements as a condition of closing
- Delayed or failed tax equity financing
For finance teams, this means FEOC documentation is now a prerequisite for transaction readiness, not a post-closing item.
The Three FEOC Tests Every Deal Team Should Understand
The IRS applies three tests to determine whether a component manufacturer qualifies as a Foreign Entity of Concern. All three must be satisfied for tax credit eligibility.
Ownership
Does a foreign adversary government or national own a significant interest in the taxpayer claiming the credit? Under the OBBBA, this threshold is 50% or more.
Effective Control
Does a foreign adversary entity exercise effective control over the taxpayer, regardless of formal ownership structure? This includes long-term licensing or royalty agreements of ten years or more with foreign-backed entities.
Material Assistance
Does equipment in the project's supply chain trace back to a Prohibited Foreign Entity? This test applies cost-ratio thresholds to components and materials sourced from PFEs, which is why supplier certificates and chain-of-custody documentation are central to compliance.
IRS Safe Harbors address only one of these three tests. The remaining two require independent verification and a structured certificate review process. That process is what tax equity counsel, credit buyers, and lenders are now requiring as a condition of financing.
What Audit-Ready FEOC Documentation Looks Like
For a project to clear FEOC diligence in a transaction, the documentation package must demonstrate:
- A complete supplier certificate review across all major components
- Chain-of-custody traceability for equipment in the supply chain
- Full SFE and FIE analysis of the taxpayer, its owners, debt holders, and counterparties
- A defensible compliance record that holds up to IRS scrutiny through the full tax credit recapture period
This is not a one-time exercise. FEOC compliance must be maintained from initial financing through the full tax credit lifecycle, including any Alteration and Repair (A&R) activity during the recapture period.
The 2026 Urgency: Why This Cannot Wait
The July 4, 2026 construction deadline.
Under the OBBBA, solar and wind projects must begin construction by July 4, 2026, to avoid the December 31, 2027 placed-in-service cliff for Section 48E and 45Y credit eligibility. This deadline is driving a wave of solar and wind transactions as developers race to monetize safe-harbored positions. Finance teams evaluating these assets need FEOC documentation in place before closing, not after.
Non-compliant inventory risk.
Many developers hold large inventories of Safe Harbored equipment that lack granular supply chain traceability. In a transaction, this creates material uncertainty for tax equity investors and lenders. Assets with unresolved FEOC exposure are trading at a discount. Assets with clean, verified documentation are positioned to transact efficiently.

Frequently Asked Questions
Does Safe Harbor protect against FEOC exposure?
No, not fully. Safe Harbor establishes the Beginning of Construction date for tax credit purposes. A pre-2026 BOC date exempts a project from the material assistance test, but the ownership and effective control tests apply to the taxpayer regardless of construction start date.
Which projects are subject to FEOC requirements?
FEOC requirements apply to clean energy projects claiming the Investment Tax Credit or Production Tax Credit, including solar, wind, and storage facilities under Sections 48E and 45Y. The ownership and effective control tests apply to the taxpayer beginning in the first taxable year after OBBBA enactment. The material assistance test applies specifically to facilities that begin construction after December 31, 2025. In practice, nearly any project monetizing these credits will have FEOC exposure to evaluate.
When should FEOC diligence begin in a transaction?
As early as possible. FEOC gaps discovered late in a transaction create delays, repricing, or failed financing. The most efficient path is FEOC documentation that is complete and current before the project enters the market.
What happens if a FEOC deficiency is found after closing?
Depending on the deficiency, the consequences can include loss of tax credit eligibility, IRS recapture, or the need to replace non-compliant equipment, all of which affect project economics and investor returns.
