NJR cautions readers that the assumptions forming the basis for forward-looking statements include many factors that are beyond NJR’s ability to control or estimate precisely, such as expectations regarding future market conditions and the behavior of other market participants. Words such as “anticipates,” “estimates,” “expects,” “projects,” “may,” “will,” “intends,” “plans,” “believes,” “should” and similar expressions may identify forward-looking statements and such forward-looking statements are made based upon management’s current expectations, assumptions and beliefs as of this date concerning future developments and their potential effect upon NJR. There can be no assurance that future developments will be in accordance with management’s expectations, assumptions and beliefs or that the effect of future developments on NJR will be those anticipated by management. Forward-looking statements in this earnings presentation include, but are not limited to, statements regarding NJR’s NFEPS guidance for fiscal 2026, including NFEPS guidance by Segment, long-term growth targets and guidance range and anticipated drivers of such growth targets, long-term annual growth projections and targets, our CIP, IIP and SAVEGREEN programs, NFEPS expectations from utility operations, Capital Plan expectations, the inclusion of our 5-year capital expenditure projections through 2030, our credit metrics, projections of dividend and financing activities, customer growth at NJNG, future NJR and NJNG capital expenditures, potential CEV capital projects, project pipeline, changes to tax laws and regulations, including those changes brought about by the passage of the Inflation Reduction Act of 2022 and the One Big Beautiful Bill Act, total shareholder return projections, dividend growth, CEV revenue and service projections, our debt repayment schedule, contributions from Leaf River as well as its potential cavern expansion, Steckman Ridge and Adelphia Gateway, SREC Hedging and long option strategies and Asset Management Agreements, our Energy Efficiency Expansion as approved by the BPU, our current and future base rate cases, our solar project pipeline and commercial solar growth goals, emissions reduction strategies and clean energy goals, changing interest rates, and other legal and regulatory expectations, and statements that include other projections, predictions, expectations or beliefs about future events or results or otherwise are not statements of historical fact. Additional information and factors that could cause actual results to differ materially from NJR’s expectations are contained in NJR’s filings with the SEC, including NJR’s Annual Reports on Form 10-K and subsequent Quarterly Reports on Form 10-Q, recent Current Reports on Form 8-K, and other SEC filings, which are available at the SEC’s web site, http://www.sec.gov. Information included in this presentation is representative as of today only and while NJR periodically reassesses material trends and uncertainties affecting NJR's results of operations and financial condition in connection with its preparation of management's discussion and analysis of results of operations and financial condition contained in its Quarterly and Annual Reports filed with the SEC, NJR does not, by including this statement, assume any obligation to review or revise any particular forward-looking statement referenced herein in light of new information future events or otherwise, except as required by law. Non-GAAP Measures This presentation includes the non-GAAP financial measures NFE/net financial loss, NFE per basic share, financial margin, utility gross margin, adjusted funds from operations, adjusted debt, and adjusted EBITDA. A reconciliation of these non-GAAP financial measures to the most directly comparable financial measures calculated and reported in accordance with GAAP can be found in the appendix to this presentation. As an indicator of NJR’s operating performance, these measures should not be considered an alternative to, or more meaningful than, net income or operating revenues as determined in accordance with GAAP. This information has been provided pursuant to the requirements of SEC Regulation G. NFE and financial margin exclude unrealized gains or losses on derivative instruments related to NJR’s unregulated subsidiaries and certain realized gains and losses on derivative instruments related to natural gas that has been placed into storage at Energy Services, net of applicable tax adjustments as described below. Financial margin also differs from gross margin as defined on a GAAP basis as it excludes certain operations and maintenance expense and depreciation and amortization [expenses] as well as the effects of derivatives as discussed above. Volatility associated with the change in value of these financial instruments and physical commodity reported on the income statement in the current period. In order to manage its business, NJR views its results without the impacts of the unrealized gains and losses, and certain realized gains and losses, caused by changes in value of these financial instruments and physical commodity contracts prior to the completion of the planned transaction because it shows changes in value currently instead of when the planned transaction ultimately is settled. An annual estimated effective tax rate is calculated for NFE purposes and any necessary quarterly tax adjustment is applied to NJR Energy Services Company. NJNG’s utility gross margin is defined as operating revenues less natural gas purchases, sales tax, and regulatory rider expense. This measure differs from gross margin as presented on a GAAP basis as it excludes certain operations and maintenance expense and depreciation and amortization. Utility gross margin may also not be comparable to the definition of gross margin used by others in the natural gas distribution business and other industries. Management believes that utility gross margin provides a meaningful basis for evaluating utility operations since natural gas costs, sales tax and regulatory rider expenses are included in operating revenues and passed through to customers and, therefore, have no effect on utility gross margin. Adjusted funds from operations is cash flows from operating activities, plus components of working capital, cash paid for interest (net of amounts capitalized), capitalized interest, the incremental change in SAVEGREEN loans, grants, rebates, and related investments, and operating lease expense. Adjusted debt is total long-term and short-term debt, net of cash and cash equivalents, excluding solar asset financing obligations but including solar contractually committed payments for sale lease-backs, debt issuance costs, and other Fitch credit metric adjustments. Adjusted EBITDA is earnings, including equity in earnings of affiliates, before interest, income taxes, depreciation and amortization, and Other Income, net, which includes non-cash earnings of AFUDC from our wholly owned subsidiaries Leaf River and Adelphia Gateway. Management uses NFE/net financial loss, utility gross margin, financial margin, adjusted funds from operations and adjusted debt as supplemental measures to other GAAP results to provide a more complete understanding of the Company’s performance. Management believes these non-GAAP measures are more reflective of the Company’s business model, provide transparency to investors and enable period-to-period comparability of financial performance. In providing NFE guidance, management is aware that there could be differences between reported GAAP earnings and NFE/net financial loss due to matters such as, but not limited to, the positions of our energy-related derivatives. Management is not able to reasonably estimate the aggregate impact or significance of these items on reported earnings and therefore is not able to provide a reconciliation to the corresponding GAAP equivalent for its operating earnings guidance without unreasonable efforts. In addition, in making forecasts relating to S&T’s Adjusted EBITDA and adjusted funds from operations and adjusted debt, management is aware that there could be differences between reported GAAP earnings, cash flows from operations and total long-term and short-term debt due to matters such as, but not limited to, the unpredictability and variability of future earnings, working capital and cash positions. Management is not able to reasonably estimate the aggregate impact or significance of these items on reported GAAP measures and therefore is not able to provide a reconciliation to the corresponding GAAP equivalent for such forecasts without unreasonable efforts. NFE/net financial loss, utility gross margin and financial margin are discussed more fully in Item 7 of our Report on Form 10-K and, we have provided presentations of the most directly comparable GAAP financial measure and a reconciliation of our non-GAAP financial measures, NFE/net financial loss, utility gross margin, financial margin, adjusted funds from operations, adjusted debt, and adjusted EBITDA to the most directly comparable GAAP financial measures, in the appendix to this presentation. This information has been provided pursuant to the requirements of SEC Regulation G.

Reconciliation of NFE and NFEPS to Net Income ($ in 000s) NFE is a measure of earnings based on the elimination of timing differences to effectively match the earnings effects of the economic hedges with the physical sale of natural gas, Solar Renewable Energy Certificates (SRECs) and foreign currency contracts. Consequently, to reconcile net income and NFE, current-period unrealized gains and losses on the derivatives are excluded from NFE as a reconciling item. Realized derivative gains and losses are also included in current-period net income. However, NFE includes only realized gains and losses related to natural gas sold out of inventory, effectively matching the full earnings effects of the derivatives with realized margins on physical natural gas flows. NFE also excludes certain transactions associated with equity method investments, including impairment charges, which are non-cash charges, and return of capital in excess of the carrying value of our investment. These are not indicative of the Company's performance for its ongoing operations. Included in the tax effects are current and deferred income tax expense corresponding with the components of NFE. NFE eliminates the impact of volatility to GAAP earnings associated with unrealized gains and losses on derivative instruments in the current period.
