What could break the thesis?
The risk has transitioned from a potential threat to an active regulatory headwind following the signing of the One Big Beautiful Bill Act (OBBB) on July 4, 2025. This law shortens the 48E credit for solar to 2027 and introduces 'Foreign Entity of Concern' (FEOC) restrictions that could deny credits for projects using certain foreign components. (3 intensifying, 1 high-severity)
“The most notable recent tax legislation affecting our business is the OBBB that President Trump signed into law on July 4, 2025. The new law adjusts tax policies that Sunrun relies upon... it shortens the availability of the 48E credit for solar facilities to the end of 2027. The law also applies new PFE restrictions to the 48E credit, which could potentially deny tax credits to entities owned, controlled, or influenced by certain specified foreign entities”
