According to the filing, OPAL Fuels Inc. issued a press release on November 9, 2026, regarding its financial results for the quarter ended September 30, 2026. The press release was furnished as Exhibit 99.1 to the Current Report. The company disclosed that the information provided under Item 2.02 of the filing is "furnished" and shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, and is therefore not subject to the liabilities of that section.

The filing noted that the report contains forward-looking statements within the meaning of federal securities laws and that "actual events or results may differ materially from those in the forward-looking statements." The company stated these forward-looking statements are based on current expectations and are not guarantees of future performance, with limitations described further in Exhibit 99.1 and other SEC reports filed by the company.

As described in the filing, OPAL Fuels uses Adjusted EBITDA as a supplemental non-GAAP financial measure. According to the company, this measure adjusts net income for items including interest and financing expense, depreciation, amortization and accretion, fair value changes, stock-based compensation, major maintenance on Renewable Power, RNG development costs, and income tax expense, among others. The filing stated that "non-GAAP financial measures are limited as an analytical tool and should not be considered in isolation from, or as a substitute for, the Company's GAAP results." Reconciliations to the most directly comparable GAAP measure are included in Exhibit 99.1.
