Insights

Insider‑linked entity acquired 3,000,000 OPAL Fuels warrants, indicating increased economic exposure.

An entity affiliated with director and 10% owner Mark S. Comora, through Fortistar LLC, acquired 3,000,000 warrants on OPAL Fuels Inc. stock. The warrants are exercisable in multiple tranches and carry forfeiture conditions, tying their value to performance under the related transaction.

The warrants were issued at a stated price of $0.0000 per warrant, so any future value would come from potential share price appreciation relative to the exercise mechanics described outside this excerpt. Because the warrants are derivative securities and subject to forfeiture, their ultimate impact depends on how many tranches vest and are exercised.

From a governance and alignment angle, this filing indicates increased indirect exposure by an insider-associated entity rather than a reduction. Future company disclosures referenced in the related March 9, 2026 Form 8-K may provide additional detail on the warrant terms and any conditions that affect exercisability and forfeiture.
