FIRST-QUARTER EARNINGS; ISSUES FISCAL 2012 EARNINGS GUIDANCE

WALL, NJ – New Jersey Resources (NYSE: NJR) today reported improved net financial earnings for the first quarter of fiscal 2012 and announced initial earnings guidance for fiscal 2012.

A reconciliation of net income to net financial earnings for the first quarter of fiscal years 2012 and 2011 is provided below.

Net financial earnings is a financial measure not calculated in accordance with generally accepted accounting principles (GAAP) of the United States as it excludes all unrealized, and certain realized, gains and losses associated with derivative instruments.

First-quarter net financial earnings at NJR were $45.3 million, or $1.09 per share, compared with $29.1 million, or $.71 per share, during the same period last year. This increase is due primarily to projects placed into service at NJR Clean Energy Ventures, the company’s renewable energy subsidiary, continued growth at New Jersey Natural Gas and improved results at NJR Energy Services.

“We are off to a strong start in fiscal 2012,” said Laurence M. Downes, chairman and CEO of NJR. “Our renewable energy strategy is taking hold and the results can be seen in strong earnings at NJR Clean Energy Ventures. Increased gross margin at our regulated business, New Jersey Natural Gas, also contributed to this quarter’s performance. We remain committed to delivering consistent returns to our shareowners.

“On behalf of our board of directors, I would like to thank all our employees for their passion and commitment, which have always been a key driver of our performance. And, with a new collective bargaining agreement set in place this quarter, I believe we have a solid foundation for future growth, as we continue to meet our customers’ expectations for safety, reliability and service.”

Subject to the risks and uncertainties identified below under “Forward-Looking Statements,” NJR announced fiscal 2012 net financial earnings guidance in a range of $2.60 to $2.80 per basic share. As in the past, NJR expects New Jersey Natural Gas to be the major contributor to fiscal 2012 net financial earnings. The following chart represents the expected contributions from NJR’s subsidiaries:

Net income at New Jersey Natural Gas (NJNG), the company’s regulated utility subsidiary, increased 6.6 percent during the first quarter of fiscal 2012 to $26 million, compared with $24.4 million during the same period last year. Steady customer growth, accelerated infrastructure investments and gross margin from incentive programs were the primary drivers.

NJNG added 2,001 new customers in the first quarter of fiscal 2012, compared with 1,640 in the same period last year. New customer conversions totaled 1,314, up from 833 in the same period last year. Additionally, 104 existing non-heat customers converted to natural gas heat, compared with 92 in the first quarter of fiscal 2011. NJNG expects these new customers and conversions to contribute approximately $1.1 million annually to utility gross margin. For more information on utility gross margin, please see Non-GAAP Financial Information below.

“With heating oil prices in the Northeast that are more than double the projected cost of natural gas on a relative basis, the conversion market at New Jersey Natural Gas is poised for continued growth,” said Downes. “In the first quarter of fiscal 2012, oil heat customers accounted for 64 percent of conversions.

“Additionally,” continued Downes, “electric prices in New Jersey remain among the highest in the country. The favorable price advantage of clean natural gas, coupled with energy-efficiency incentives, will help sustain continued steady customer growth and go a long way toward supporting the state’s goals to reduce both greenhouse gas emissions and energy costs for its residents.”

NJNG expects to add, in total, approximately 12,000 to 14,000 new customers during fiscal 2012 and 2013, which would represent a growth rate of 1.3 percent.

During the first three months of fiscal 2012, NJNG’s gross margin-sharing incentive programs, which include off-system sales, capacity release, storage optimization and financial risk management programs, generated utility gross margin of $2.8 million, compared with $2.7 million for the same period last year. NJNG shares the gross margin earned from these incentive programs with customers and shareowners according to a gross margin-sharing formula authorized by the New Jersey Board of Public Utilities (BPU) and in place through October 31, 2015. Since inception in 1992, these incentive programs have saved customers over $556 million.

The second phase of NJNG’s Accelerated Infrastructure Program (AIP II), designed to expedite previously planned capital expenditures, continues to help ensure the safety and integrity of the company’s distribution system. All nine AIP II projects are in the design or construction phase including the largest project, an $18 million investment in Monmouth County, which began in November 2011. NJNG expects all projects under AIP II to be completed by October 2012. NJNG’s $60.2 million investment in the nine AIP II projects is authorized by the BPU to earn an overall return of 7.12 percent, which includes a 10.3 percent return on equity.

AIP projects also help grow the state’s economy through job creation. According to a study by the Rutgers’ Bloustein School of Planning and Public Policy on the “Economic Impacts of Energy Infrastructure Investments,” commissioned by NJNG, 7.8 jobs are created for every $1 million the company spends on AIP projects.

On January 18, 2012, the BPU extended NJNG’s highly successful SAVEGREEN Project through December 31, 2012, approving an additional $19.4 million in incentives and rebates for customers who make energy-efficiency home improvements. No immediate rate change will result from this approval and the company will earn an overall return of 7.10 percent, which includes a 10.3 percent return on equity, on $18.4 million of the incentives and rebates. Additionally, NJNG will recover $1 million of incentives related to customer conversions over a five-year period.

In the first quarter of 2012, SAVEGREEN performed 1,651 home energy audits and paid $2.3 million in rebates and incentives to customers. Over 1,000 additional audits are scheduled through February 2012. The energy-efficiency rebates, incentives and repayment options offered through The SAVEGREEN Project help

customers make the switch to clean, energy-efficient natural gas, advancing the state’s environmental goals and its mandate to reduce energy costs for residents. Additionally, since its inception in 2009, over 1,000 contractors have participated in The SAVEGREEN Project. These local contractors have reaped the benefits of a capital investment of more than $88 million to date.

Entering its second year of operations, net income for the first quarter of fiscal 2012 at NJR Clean Energy Ventures (NJRCEV), NJR’s renewable energy subsidiary, was $10.1 million compared with $54,000, in the same period last year. NJRCEV completed several projects in the first quarter of fiscal 2012, including the 3.6 megawatt project at the Village of Manalapan, the remaining 25 percent of a 4.7 megawatt system in Vineland, New Jersey and the 1.3 megawatt system across two rooftops in Edison, New Jersey.

NJRCEV also placed into service a 14.1 megawatt solar system built on McGraw-Hill’s East Windsor, New Jersey campus. This $59.5 million project, originally scheduled for completion in March of 2012, is NJRCEV’s largest single investment to date.

These solar installations are the latest commercial projects completed by NJRCEV. The company has invested approximately $123 million in rooftop and ground-mounted solar systems with a total capacity of 27.6 megawatts in Monmouth, Mercer, Middlesex and Cumberland counties in New Jersey.

“New Jersey recognizes the benefits of renewable energy and so does NJR,” said Downes. “It’s consistent with our core energy strategy, our commitment to the environment and our mission to reduce energy usage and lower prices for our customers. Both residential and commercial customers will benefit from the projects and programs NJR Clean Energy Ventures has put into place and our shareowners are benefiting from these investments as well.”

In the first quarter of fiscal 2012, The Sunlight Advantage^TM, NJRCEV’s residential solar lease program, added 140 customers bringing the total number of customers to 489 since inception. The Sunlight Advantage provides simple, solar savings to eligible homeowners through a roof-mounted solar system with no upfront installation or maintenance costs. NJRCEV expects to invest approximately $14.2 million in residential solar systems in fiscal 2012.

NJR’s effective tax rate is significantly impacted by the amount of investment tax credits (ITCs) earned during the fiscal year. GAAP requires NJR to estimate its annual effective tax rate and use this rate to calculate its year-to-date tax expense/benefit. Based on the commercial projects completed in the first quarter and NJRCEV’s forecast for residential projects for the balance of the fiscal year, NJR used an effective tax rate of 21.9 percent in the first quarter of fiscal 2012. Accordingly, $11.3 million related to ITCs was recognized in the first fiscal quarter.

The estimate is based on information and assumptions that are subject to change, and may have a material impact on quarterly and annual net financial earnings. Factors considered by management in estimating completion of projects during the fiscal year include, but are not limited to, board of directors’ approval, execution of various contracts, including power purchase agreements, construction logistics, permitting and interconnection completion. See the “Forward-Looking Statements” section of this news release for further information regarding the inherent risks associated with solar investments.

Net financial earnings at NJR Energy Services (NJRES), the wholesale energy services subsidiary of NJR, were $7.6 million during the first quarter of fiscal 2012, compared with $3.2 million in the same period last year. The increase was due primarily to higher revenue from fee-based elements of transactions executed with producers in the Marcellus Shale region, and an improvement in transportation arbitrage opportunities, as compared with the prior year. However, as indicated in NJRES’ earnings guidance above, relatively low natural gas prices and reduced volatility in the wholesale markets are expected to negatively impact comparable results over the balance of the fiscal year.

NJRES develops and manages a diverse portfolio of over 36.5 Bcf of firm storage capacity and 1.1 Bcf/day of firm transportation. With the value of capacity and storage affected by abundant supply and historically low prices, NJRES continues to focus on providing producer services in the Marcellus Shale and other natural gas producing regions. By using its extensive transportation and storage assets, and expanding expertise in the natural gas liquids arena, NJRES offers producers the opportunity to increase the value of their product while enhancing its profitability.

NJR Energy Holdings, which owns the company’s natural gas storage and transportation pipeline investments, including NJR’s 50 percent equity ownership in Steckman Ridge and its 5.53 percent equity investment in the Iroquois Pipeline, reported net income in the first quarter of fiscal 2012 of $1.8 million, compared with $1.7 million in the same period last year.

Steckman Ridge, a 12 Bcf working natural gas storage facility in southwestern Pennsylvania with Spectra Energy, generated $1.1 million in earnings for the first quarter of fiscal 2012, slightly higher than the first quarter of fiscal 2011. NJR’s equity investment in the Iroquois Pipeline, which brings natural gas from eastern Canada to the metropolitan region, contributed $715,000 to first-quarter 2012 earnings, compared with $662,000 in the same period last year.

Earnings at NJR’s Retail and Other operation, which consists primarily of NJR Home Services (NJRHS), the company’s appliance service subsidiary, improved slightly in the first quarter of fiscal 2012. Revenue for NJRHS in the first quarter of fiscal 2012 was $8.4 million, a 12 percent increase over the same period last year. These improved results were due primarily to growth in its backup generator business, equipment sales and solar installations, as well as the continued growth of its Premier Heating and Cooling Plans. NJRHS serves over 130,000 customers.

NJR purchased 83,600 shares of common stock under its share repurchase plan during the first quarter of fiscal 2012 at a cost of $3.7 million. The plan authorizes NJR to purchase its shares on the open market or in negotiated transactions, based on market and other financial conditions. Since its inception in September 1996, NJR has invested nearly $222 million to repurchase 7.4 million shares at a split-adjusted, average price of $30.10. Approximately 1.4 million shares remain authorized for purchase under the repurchase plan.

Non-GAAP Financial Information

financial measures calculated and reported in accordance with GAAP, can be found below. As an indicator of the company’s operating performance, these measures should not be considered an alternative to, or more meaningful than, operating income as determined in accordance with GAAP.

Net financial earnings (losses) and financial margin exclude 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. 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. NJNG’s utility gross margin represents the results of revenues less natural gas costs, sales and other taxes and regulatory rider expenses, which are key components of the company’s operations that move in relation to each other. Natural gas costs, sales and other taxes and regulatory rider expenses are passed through to customers and therefore have no effect on gross margin. Management uses these non-GAAP financial measures 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. A reconciliation of all non-GAAP financial measures to the most directly comparable financial measures calculated and reported in accordance with GAAP, can be found below. For a full discussion of NJR’s non-GAAP financial measures, please see NJR’s most recent Form 10-K, Item 7.
