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 presentation include, but are not limited to, certain statements regarding NJR’s NFE guidance for fiscal 2018, forecasted contribution of business segments to fiscal 2018 NFE, future NJNG customer growth, future NJR capital expenditures and infrastructure investments, NJRCEV’s ITC-eligible projects and demand for residential solar, SREC prices and electricity sales future base rate cases, earnings and dividend growth, the ability to close and successfully implement the Adelphia Gateway acquisition, as well as the SRL and PennEast Pipeline projects. The factors that could cause actual results to differ materially from NJR’s expectations include, but are not limited to, risks associated with our investments in clean energy projects, including the availability of regulatory and tax incentives, the availability of viable projects, our eligibility for ITCs and PTCs, the future market for SRECs and electricity prices, and operational risks related to projects in service; the ability to obtain governmental and regulatory approvals, land-use rights, electric grid connection (in the case of clean energy projects) and/or financing for the construction, development and operation of our unregulated energy investments and NJNG’s infrastructure projects in a timely manner; risks associated with acquisitions and the related integration of acquired assets with our current operations; volatility of natural gas and other commodity prices and their impact on NJNG customer usage, NJNG’s BGSS incentive programs, our Energy Services segment operations and on our risk management efforts; the level and rate at which NJNG’s costs and expenses are incurred and the extent to which they are approved for recovery from customers through the regulatory process, including through future base rate case filings; the impact of a disallowance of recovery of environmental-related expenditures and other regulatory changes; the performance of our subsidiaries; operating risks incidental to handling, storing, transporting and providing customers with natural gas; access to adequate supplies of natural gas and dependence on third-party storage and transportation facilities for natural gas supply; the regulatory and pricing policies of federal and state regulatory agencies; timing of qualifying for ITCs and PTCs due to delays or failures to complete planned solar and wind energy projects and the resulting effect on our effective tax rate and earnings; the results of legal or administrative proceedings with respect to claims, rates, environmental issues, gas cost prudence reviews and other matters; risks related to cyberattack or failure of information technology systems; changes in rating agency requirements and/or credit ratings and their effect on availability and cost of capital to our company; the ability to comply with current and future regulatory requirements; the impact of volatility in the equity and credit markets on our access to capital; the impact to the asset values and resulting higher costs and funding obligations of our pension and postemployment benefit plans as a result of potential downturns in the financial markets, lower discount rates, revised actuarial assumptions or impacts associated with the Patient Protection and Affordable Care Act; commercial and wholesale credit risks, including the availability of creditworthy customers and counterparties, and liquidity in the wholesale energy trading market; accounting effects and other risks associated with hedging activities and use of derivatives contracts; the ability to optimize our physical assets; any potential need to record a valuation allowance for our deferred tax assets; changes to tax laws and regulations; weather and economic conditions; the ability to comply with debt covenants; demographic changes in NJR’s service territory and their effect on NJR’s customer growth; the impact of natural disasters, terrorist activities and other extreme events on our operations and customers; the costs of compliance with present and future environmental laws, including potential climate change-related legislation; environmental-related and other uncertainties related to litigation or administrative proceedings; risks related to our employee workforce; and risks associated with the management of our joint ventures and partnerships, and investment in a master limited partnership. The aforementioned factors are detailed in the “Risk Factors” sections of our Form 10-K that we filed with the Securities and Exchange Commission (SEC) on November 21, 2017, which is available on the SEC’s website at 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 future events. .

3 Non-GAAP Financial Measures This presentation includes the non-GAAP measure, NFE. As an indicator of the Company’s operating performance, this measure should not be considered an alternative to, or more meaningful than, GAAP measures, such as cash flow, net income, operating income or earnings per share. NFE excludes unrealized gains or losses on derivative instruments related to the Company’s unregulated subsidiaries and certain realized gains and losses on derivative instruments related to natural gas that has been placed into storage at NJRES, net of applicable tax adjustments, as described below. Volatility associated with the change in value of these financial and physical commodity contracts is reported in 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 as opposed to 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 NJRCEV, as such adjustment is related to tax credits generated by NJRCEV. Management uses NFE as a supplemental measure to other GAAP results to provide a more complete understanding of the Company’s performance. Management believes this non-GAAP measure is more reflective of the Company’s business model, provides transparency to investors and enables period-to-period comparability of financial performance. In providing fiscal 2018 earnings guidance, management is aware that there could be differences between reported GAAP earnings and NFE 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 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. For a full discussion of our non- GAAP financial measures, please see NJR’s most recent Form 10-K, Item 7. This information has been provided pursuant to the requirements of SEC Regulation G.
