Forward-Looking Statements and Disclaimer Forward Looking Statements This presentation contains forward-looking statements related to the operations of the Partnership that are based on management’s current expectations, estimates, and projections about its operations. You can identify many of these forward-looking statements by words such as “believe,” “expect,” “intend,” “project,” “anticipate,” “estimate,” “continue,” “if,” “outlook,” “will,” “could,” “should,” or similar words or the negatives thereof. Forward-looking statements include, among other things, statements about the potential benefits of the proposed transaction; the prospective performance and outlook of the Partnership’s business, performance and opportunities following the completion of the transaction, including the ability of the parties to complete the proposed transaction and the expected timing of completion of the proposed transaction; as well as any assumptions underlying any of the foregoing. You are cautioned not to place undue reliance on any forward-looking statements, which can be affected by assumptions used or by known risks or uncertainties. Consequently, no forward-looking statements can be guaranteed. When considering these forward-looking statements, you should keep in mind the risk factors noted below and other cautionary statements in this presentation. The risk factors and other factors noted throughout this presentation could cause actual results to differ materially from those contained in any forward-looking statement. Known material factors that could cause the Partnership’s actual results to differ materially from the results contemplated by such forward-looking statements include, among others, risks related to the ability of the parties to complete the proposed transaction on the proposed terms and schedule, including obtaining required regulatory approvals; risks associated with the proposed transaction, such as that the expected benefits of the proposed transaction will not occur; risks related to future opportunities and plans for the Partnership, including uncertainty regarding the expected financial performance and results of the Partnership following completion of the proposed transaction; disruption from the proposed transaction, making it more difficult to conduct business as usual or maintain relationships with customers, employees or suppliers; and the possibility that if the Partnership does not achieve the perceived benefits of the proposed transaction as rapidly or to the extent anticipated by financial analysts or investors, the market price of the Partnership’s common units could decline, as well as other risks related to the Partnership’s business and the factors described in Part I, Item 1A of the Partnership’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, which was filed with the Securities and Exchange Commission (the “SEC”) on February 11, 2025, Part II Item 1A of the Partnership’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, which was filed with the SEC on May 6, 2025, and subsequently filed reports. All forward-looking statements speak only as of the date of this presentation and are expressly qualified in their entirety by the foregoing cautionary statements. Unless legally required, the Partnership undertakes no obligation to update publicly any forward-looking statements, whether as a result of new information, future events, or otherwise. Unpredictable or unknown factors not discussed herein also could have material adverse effects on forward-looking statements. Non-GAAP Financial Information This presentation refers to the Non-GAAP financial measure of Distributable Cash Flow. The Partnership defines Distributable Cash Flow as net income (loss) plus non-cash interest expense, non-cash income tax expense (benefit), depreciation and amortization expense, unit-based compensation expense (benefit), impairment of assets, impairment of goodwill, certain transaction expenses, severance charges and other employee costs, loss (gain) on disposition of assets, loss on extinguishment of debt, change in fair value of derivative instrument, proceeds from insurance recovery, and other, less distributions on preferred units and maintenance capital expenditures. Management believes Distributable Cash Flow is an important measure of operating performance because it allows management, investors, and others to compare the cash flows that the Partnership generates (after distributions on Preferred Units but prior to any retained cash reserves established by the Partnership’s general partner and the effect of the Distribution Reinvestment Plan) to the cash distributions that the Partnership expects to pay its common unitholders. This presentation also references a forward-looking estimate of Adjusted EBITDA projected to be generated by J-W Power Company for its 2026 fiscal year. The Partnership defines J-W Power Company’s EBITDA as net income (loss) before net interest expense, depreciation and amortization expense, and income tax expense (benefit). The Partnership defines J-W Power Company’s Adjusted EBITDA as EBITDA plus impairment of assets, impairment of goodwill, interest income on capital leases, severance charges and other employee costs, certain transaction expenses, loss (gain) on disposition of assets, loss on extinguishment of debt, loss (gain) on derivative instrument, and other. The Partnership is unable to reconcile this estimated Adjusted EBITDA to projected net income (loss) and projected net cash provided by operating activities, the most comparable financial measures calculated in accordance with GAAP because components of the required calculations cannot be reasonably estimated, such as changes to current assets and liabilities, unknown future events, and estimating certain future GAAP measures. The inability to project certain components of the calculation would significantly affect the accuracy of the reconciliations. These non-GAAP financial measures should not be considered alternatives to, or more meaningful indicators of, J-W Power Company’s or the Partnership’s financial measures as prepared in accordance with GAAP. The Partnership’s methods of determining these non-GAAP financial measures may differ from the methods used by other companies and may not be comparable.
