Foreign Entity of Concern rules are no longer a footnote — miss the material assistance threshold and you lose the entire §45X, §45Y, or §48E credit, not a haircut. Why sound projects are suddenly unfinanceable, and why the window is measured in months.
There is a quiet crisis building in clean energy tax credit financing, and most developers do not see it coming until it is too late.
It is called FEOC — Foreign Entity of Concern — and under the One Big Beautiful Bill Act, it is not a footnote anymore. It has become an all-or-nothing gate on §45X, §45Y, and §48E eligibility.
Here is what makes it dangerous: this is not like the old domestic content bonus adders, where missing a threshold cost you a 10% bump. Miss the FEOC material assistance threshold on your supply chain, and you lose the entire credit. Not a haircut. The whole thing.
And the clock has already started. Projects that began construction before July 4, 2025 mostly sit outside the framework. Construction between July and December 2025 triggers entity-level restrictions only. Anything starting January 1, 2026 or later faces the full framework — component-level tracing, the material assistance cost ratio, and no more 5% safe harbor to fall back on.
The practical effect: real deals are stalling right now. Manufacturers are refusing to sign updated transfer agreements once FEOC representations get added. Buyers are walking away from credits they would have bought without hesitation eighteen months ago. Projects with strong fundamentals are suddenly unfinanceable — not because the economics changed, but because the eligibility question became unanswerable in the time a lender needs to close.
We have been working on a structure to help developers move through this window before it fully closes — not around the rules, but ahead of the timing that determines which rules apply to a given project.
If you are sitting on a project where FEOC exposure is the thing nobody on your cap table wants to say out loud, the window to do something about it is measured in months, not years. It is worth a conversation.
