The renewable energy M&A landscape just experienced its most dramatic shift since the Investment Tax Credit's original creation. With the One Big Beautiful Bill Act (OBBBA) signed into law on July 4, 2025, every renewable acquisition now requires a fundamentally different due diligence approach—one that could mean the difference between a profitable deal and a complete write-off.

The New Reality: Compressed Timelines and Foreign Entity Restrictions

Critical Deadline Changes

Under OBBBA, wind and solar projects must either be completed by the end of 2027 or begin construction within the next 12 months to qualify for tax credits. This represents a dramatic acceleration from previous timelines where projects beginning construction in 2025 or 2026 would have until the end of 2029 or 2030, respectively, to be placed in service.

Timeline Risk Matrix: Pre-OBBBA vs. Post-OBBBA

Project Status	Pre-OBBBA Timeline	Post-OBBBA Timeline	Credit Risk Level	Valuation Impact
Construction started 2024	PIS by 2028-2029	PIS by 2028-2029	Low	No change
Construction starting 2025	PIS by 2029-2030	PIS by 2027	Moderate	5-15% discount
Construction starting 2026	PIS by 2030	PIS by 2027	High	25-40% discount
Construction post-2026	PIS by 2030+	No credits available	Critical	50-70% discount

New Foreign Entity Restrictions

The OBBBA implements a regime restricting interactions with "Prohibited Foreign Entities" (PFEs), including both Specified Foreign Entities (SFEs) and Foreign Influenced Entities (FIEs).

• Projects beginning construction after December 31, 2025, cannot receive "material assistance" from PFEs
• Tax credits may not be transferred to "specified foreign entities"
• Material assistance cost ratios with specific threshold percentages based on construction year

Your Updated M&A Due Diligence Checklist

Phase 1: Timeline Viability Assessment

Critical Questions:

• Does the project realistically achieve commercial operation by December 31, 2027?
• What specific milestones remain, and what's the risk-adjusted timeline for each?
• Are there any dependencies on foreign-manufactured components that trigger PFE restrictions?

Valuation Impact: Projects missing the 2027 deadline lose 100% of federal tax credit value—typically 20-30% of total project value.

Phase 2: Foreign Entity Supply Chain Analysis

Foreign Entity Due Diligence Checklist

Risk Category	Due Diligence Requirement	Documentation Standard	Penalty Risk
Direct Ownership	Full ownership chain mapping	Certified ownership structures	High - Credit disqualification
Supply Chain	Component-level manufacturer review	Written supplier certifications	$5,000 or 10% of credit
Material Assistance	Cost ratio calculations by construction year	Binding contract documentation	20% penalty on understatement
Counterparty Screening	Investor, lender, contractor review	SFE/FIE compliance certificates	Medium - Deal restructuring
Ongoing Monitoring	Annual compliance verification	Updated certifications required	High - Ongoing exposure

Phase 3: Tax Credit Transferability and Structure

Updated Considerations:

• Tax credit transferability provisions remain available but with restrictions on foreign entity buyers
• $33 billion tax equity market in 2024 demonstrates continued appetite, but buyer universe may narrow
• 100% bonus depreciation made permanent for property placed in service after January 19, 2025

Phase 4: Technology-Specific Risk Assessment

Wind and Solar Projects:

• Begin construction deadline more explicitly defined using IRS Notice 2013-29 and 2018-59 rules
• Executive order directing Treasury to "strictly enforce" termination and prevent "artificial acceleration" of construction
• Projects over 1GW on federal land with BLM rights-of-way before June 16, 2025, may have different rules

Other Technologies:

• Battery storage and carbon capture projects largely preserve tax credits into the next decade
• Clean hydrogen PTC terminates for projects beginning construction after 2027
• Nuclear and geothermal projects maintain extended timelines through 2033

Deal Structure Adaptations for the New Environment

Timeline-Driven Mechanisms

Given compressed deadlines, successful M&A structures now incorporate:

Deal Structure Matrix: Timeline-Driven M&A Mechanisms

Risk Level	Base Structure	Payment Terms	Risk Allocation	Due Diligence Period
Low Risk (COD by 2026)	Traditional acquisition	80% at close, 20% at COD	Standard dev risk to seller	8-12 weeks
Moderate Risk (COD by 2027)	Staged acquisition	60% at close, 40% milestone-based	Shared timeline risk	6-8 weeks
High Risk (COD uncertain)	Asset acquisition	40% at close, 60% contingent	Timeline risk to seller	4-6 weeks
Critical Risk (Post-2027)	Opportunistic buy	Asset value only	No federal credit assumptions	2-4 weeks

Enhanced Due Diligence Requirements

Foreign Entity Compliance:

• Pre-closing supplier certification programs
• Ongoing monitoring and replacement protocols for non-compliant suppliers
• Insurance products covering PFE compliance risks

Accelerated Development Oversight:

• Joint development committees with buyer participation
• Milestone-based funding releases
• Buyer approval rights for major vendor changes

Risk-Adjusted Valuation Framework

High-Certainty Projects (COD by 2026):

• Full federal tax credit value (30% ITC equivalent)
• Standard development risk premiums apply
• Focus on execution capability rather than timeline risk

Moderate-Risk Projects (COD by 2027):

• 15-25% discount for timeline uncertainty
• Enhanced due diligence on critical path items
• Structured risk-sharing between buyer and seller

High-Risk Projects (COD uncertain or post-2027):

• 40-60% discount reflecting tax credit loss risk
• Asset-value-only pricing models
• Potential for opportunistic acquisition strategies

The Strategic Imperative: Speed and Compliance

The OBBBA has fundamentally altered the renewable M&A equation. With policy uncertainty under the new administration and 3% annual load growth driving demand, the market is simultaneously experiencing headwinds and tailwinds.

Winner's Strategies:

• Accelerated due diligence processes (6-8 weeks instead of 12-16)
• Enhanced in-house PFE compliance capabilities
• Timeline-focused deal structures that share construction risk
• Deep supply chain intelligence and alternative vendor relationships

Loser's Risks:

• Traditional 6-month due diligence timelines that miss construction deadlines
• Surface-level foreign entity reviews that miss critical supplier relationships
• Static deal structures that don't account for regulatory timeline pressure
• Overreliance on historical development timeline assumptions
