NEW JERSEY RESOURCES ANNOUNCES FISCAL 2013

FIRST-QUARTER EARNINGS; REAFFIRMS FISCAL 2013 EARNINGS GUIDANCE

WALL, NJ – New Jersey Resources (NYSE: NJR) today reported net financial earnings for the first quarter of fiscal 2013 and reaffirmed earnings guidance for fiscal 2013.

A reconciliation of net income to net financial earnings for the first quarter of fiscal years 2013 and 2012 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. For further discussion of this financial measure, as well as reconciliation to the most comparable GAAP measure, please see the explanation below under “Additional Non-GAAP Financial Information.”

First-quarter net financial earnings for fiscal 2013 at NJR were $35.5 million, or $.85 per share, compared with $45.3 million, or $1.09 per share, during the same period last year. This decrease, which was expected, is due primarily to lower earnings at NJR Clean Energy Ventures and NJR Energy Services.

“A fundamental measure of our success over the years is the trust our shareowners have placed in us. This is a responsibility we take very seriously,” said Laurence M. Downes, chairman and CEO of New Jersey Resources. “We thank them for their continued confidence as we work diligently to create value and opportunity for all our shareowners. We fully expect our results for the rest of the fiscal year to exceed last year.”

“On behalf of our board of directors, I would like to thank each and every one of our employees for their unwavering dedication during this extraordinary time in the history of our company. I have never been more proud of our team and their commitment in the wake of Superstorm Sandy. As we move beyond storm recovery, I am confident we will continue to rise to the challenge and meet the expectations of all our stakeholders.”

Subject to the risks and uncertainties identified below under “Forward-Looking Statements,” NJR is reaffirming fiscal 2013 net financial earnings guidance previously announced on January 22, 2013, in a range of $2.55 to $2.75 per basic share. As in the past, NJR expects New Jersey Natural Gas to be the largest contributor to fiscal 2013 net financial earnings. The following chart represents the expected contributions from NJR’s subsidiaries:

Net financial earnings for the first quarter of fiscal 2013 at New Jersey Natural Gas (NJNG), the company’s regulated utility subsidiary, were $25.5 million, compared with $26 million during the same period last year. Lower gross margin due to the effects of Superstorm Sandy more than offset the impact of customer additions and lower operation and maintenance expenses. Based on our restoration efforts, customer growth projection and updated forecast, we expect NJNG’s results for the balance of this year to exceed last year.

“At its heart, our principal subsidiary, New Jersey Natural Gas, is an infrastructure company. And that’s where Superstorm Sandy hit us hardest,” continued Downes. “However, significant progress has been made and I am proud to report that about 95 percent of our impacted customers now have natural gas service available. This is a true testament to our dedicated team of employees”

NJNG added 1,959 new customers in the first quarter of fiscal 2013, compared with 2,001 in the same period last year. The conversion market remains strong with new customer conversions totaling 1,114, representing nearly 57 percent of new customer additions. Additionally, 62 existing non-heat customers converted to natural gas heat. NJNG expects these new customers and conversions to contribute approximately $1 million annually to utility gross margin.

NJNG has increased its two-year projected customer growth additions for 2013 and 2014 from a range of 12,000 to 14,000 to a range of 12,500 to 14,500, representing a new customer annual growth rate of 1.3 to 1.4 percent. For more information on utility gross margin, please see Non-GAAP Financial Information below.

Capital expenditures related to Superstorm Sandy are estimated at $30 to $40 million, down from the original estimate of $40 to $60 million. NJNG expects to spend approximately $20 to $27 million of this amount in fiscal 2013, with the balance invested over the next three fiscal years. The primary reason for the decrease is less main replacement compared with original estimates and the lower cost of equipment replacements. As with normal operations, capital costs will be treated as additions to NJNG’s rate base on which recovery will be sought in a future base rate case, which will be filed no later than November 15, 2015.

Total incremental operation and maintenance costs are estimated at $15 to $20 million. NJNG is deferring these costs and, therefore, such costs will have no impact on fiscal 2013 earnings. NJNG intends to seek recovery of these deferred costs in the future base rate case.

During the first three months of fiscal 2013, 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 $2.1 million, compared with $2.8 million for the same period last year. This decrease is due primarily to decline in capacity value. 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 $600 million.

In the first quarter of fiscal 2013, The SAVEGREEN Project, NJNG’s energy-efficiency program, paid $2 million in rebates and incentives to NJNG customers. These rebates, incentives and repayment options 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. During the same period, SAVEGREEN performed 1,194 home energy audits to identify energy-efficiency opportunities with an emphasis on whole-house improvements to further increase energy savings.

Since its inception in 2009, SAVEGREEN has helped over 20,209 customers save on their energy costs with rebates and incentives totaling $31.2 million. With 1,387 contractors now participating, the program has also resulted in over $143.7 million in economic activity for New Jersey. NJNG is authorized to earn an overall return of 7.76 percent on its 2009, 2010 and 2011 SAVEGREEN investments and 7.1 percent on its 2012 investments, all of which include a 10.3 percent return on equity, with an equity ratio of 51.2 percent.

NJNG filed with the BPU on July 6, 2012 to extend and modify SAVEGREEN through December 2016. On January 25, 2013, the BPU extended the company’s current SAVEGREEN Program through June 30, 2013, while discussions continue on NJNG’s proposed extension of SAVEGREEN.

Net financial earnings for the first quarter of fiscal 2013 at NJR Clean Energy Ventures (NJRCEV), the company’s renewable energy segment, were $5.3 million, compared with $10.1 million in the same period last year. The year-over-year reduction in earnings is due primarily to a decline in investment tax credits (ITCs) associated with the size of projects placed in service.

During the first quarter of fiscal 2013, NJRCEV placed into service a $19.7 million, 6.7 megawatt ground-mounted Reeves Station project in Medford, New Jersey as well as a $6.6 million, 2.4 megawatt rooftop project, which will supply power to the Wakefern Food Corp. distribution center in Keasbey, New Jersey. NJRCEV also executed an agreement with Medford Township to construct, own and operate a 1.5 megawatt solar system at their Wastewater Treatment Plant. The project is expected to be operational during the third quarter of fiscal 2013.

In the first quarter of fiscal 2012, NJRCEV placed into service a total of $89.9 million in commercial projects, including a $59.5 million, 14.1 megawatt solar system built on McGraw-Hill’s East Windsor, New Jersey campus, NJRCEV’s largest single investment to date.

“Renewable energy presents another long-term growth opportunity for our shareowners,” says Downes. “Our solar investments align with our core energy strategy as well as the state’s Energy Master Plan and help lower energy costs for both our residential and commercial customers.”

The Sunlight Advantage, NJRCEV’s residential solar lease program, added 103 customers in the first quarter of fiscal 2013, bringing the total number of customers to 1,230 since program 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 $23 million in residential solar systems in fiscal 2013

NJR’s effective tax rate is significantly impacted by the amount of 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 provision. 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 28.5 percent in the first quarter of fiscal 2013. Accordingly, $6.8 million related to ITCs were recognized in the first fiscal quarter. In the first quarter of fiscal 2012, $11.3 million related to ITCs were recognized.

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.

First-quarter 2013 net financial earnings for NJR Energy Services (NJRES), the wholesale energy subsidiary of NJR, were $3 million, compared with $7.6 million in the same period last year. This decrease is due primarily to lower margin from transportation assets in the current year, compared with the same period last year, partially offset by higher margin from storage assets. Based on results through January and an updated forecast, NJRES’ results for the entire year are expected to exceed last year.

NJRES continues to identify new growth opportunities in the producer services marketplace. NJRES also added new counterparties, as well as strategic storage and transportation assets to its holdings, and continues to expand its geographic footprint by adding Rockies and Pacific Northwest assets to its existing portfolio, which includes 35.3 billion cubic foot (Bcf) of firm storage capacity and 1.27 Bcf/day of firm transportation.

NJR’s natural gas storage and transportation pipeline segment, NJR Energy Holdings, reported first-quarter fiscal 2013 net financial earnings of $1.8 million, the same as fiscal 2012. This segment consists of NJR’s 50 percent equity ownership in Steckman Ridge, a 12 Bcf natural gas storage facility in southwestern Pennsylvania jointly owned with Spectra Energy and NJR’s 5.5 percent equity investment in Iroquois Pipeline, which brings natural gas from eastern Canada to the New York/New Jersey metropolitan region.

NJR Home Services (NJRHS), the company’s unregulated retail and appliance service subsidiary, reported a net financial earnings loss of $247,000, compared with a loss of $442,000 in the same period last year. Revenue for NJRHS in the first quarter was $10.6 million, an 18 percent increase over the same period last year, and gross profit improved 25 percent in the first quarter of 2013, compared with the same period last year. This improved performance was due to growth in NJRHS’ installation business.

As a result of recent storms and the need for many homeowners to replace their home comfort systems, heating equipment and standby generator sales and installations are strong. NJRHS continues to market its line of products and services, including its Premier Comfort Plans, to its newly expanded territory, including Sussex, Warren and Hunterdon counties in New Jersey. NJRHS serves nearly 130,000 customers.

Net financial earnings 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. 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. Management uses this non-GAAP financial measure 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. A reconciliation of all non-GAAP financial measures used by NJR 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.
