FOR IMMEDIATE RELEASE APRIL 16, 2003 PHONE: 609-561-9000 INVESTOR RELATIONS CONTACT: STEPHEN CLARK x4260 MEDIA CONTACT: JOANNE BRIGANDI x4240 SJI Reports a 16 Percent Increase in First Quarter Earnings FOLSOM, NJ -- South Jersey Industries (NYSE: SJI) today reported earnings from continuing operations of $22.8 million, or $1.86 per share, for the first quarter of 2003 compared with $19.7 million, or $1.65 per share, for the same quarter in 2002. "Strong performance for the quarter puts SJI on track to deliver earnings per share growth in excess of the 6 to 7 percent we previously forecasted for 2003," stated Charles Biscieglia, chairman and CEO of SJI. "The combination of effective strategies and dedicated, talented employees has enabled SJI to post record results for four consecutive years, and we've just gotten off to a good start on a fifth." Record performance for the quarter, which represents a 16 percent increase over the prior year period, was due to improved performance from both utility and non-utility activities. -MORE- SJI ADD 1 Highlights from the quarter include: * Income from Utility Operations Grows 15 Percent -Utility operations' contribution to net earnings increased to $19.4 million in the first quarter of 2003, compared with $16.9 million for the first quarter of 2002. Record performance was mostly due to customer growth and colder weather. Off-system sales of natural gas and transportation /storage capacity, coupled with appliance service activities, contributed $2.3 million to this year's performance. * Strong Utility Customer Growth Trend Continues - Utility operations added 2,393 customers in the quarter, despite difficult weather conditions, and expects to maintain the customer growth rate achieved in 2002 of approximately 3 percent. In 2002, SJG was the fastest growing gas utility in New Jersey. Total customers as of March 31, 2003 were 298,767 compared with 290,604 at the same point last year. * Cold Weather at Last - Weather for the first quarter of 2003 was 27.7 percent colder than an extremely warm 2002, and 6.2 percent colder than the 20-year norm. Weather positively impacted the earnings contribution of SJI's utility business. However, as expected, the utility's temperature adjustment clause (TAC) and operating expenses directly related to the cold weather mitigated the overall net income benefit of weather. -MORE- SJI ADD 2 SJI's TAC limits the impact of temperature variations on SJI's earnings and customer bills. In the first quarter of 2003, the TAC will provide utility customers with credits of $2.3 million. The TAC provided SJI with a $3.0 million earnings benefit during the extremely warm first quarter in 2002. * Income from Non-utility Operations Jumps 22 Percent - SJI's non-utility operations' contribution to net income increased to $3.4 million for the first three months of 2003 compared with $2.8 million in the prior-year period. Substantial numbers of new retail gas marketing customers obtained by South Jersey Energy during the last 12 months primarily drove performance. * Retail Gas Marketing Customer Base Increases 8 Percent- SJI's retail gas marketing business added 6,324 customers in the first quarter of 2003 as consumers continued to recognize South Jersey Energy as a reliable, cost-effective natural gas provider. Gas marketing customers totaled 82,543 at March 31, 2003 compared with 46,736 customers on March 31, 2002. * SJI Receives High Marks for Corporate Governance - Institutional Shareholder Services, a noted independent provider of corporate governance analysis for investors, ranked SJI above 97 percent of the companies listed in the Russell 3000 and above 90 percent of utility companies on the governance issue. The ranking focuses on factors such as board independence and executive incentive plans. - -MORE- SJI ADD 3 EARNINGS CONFERENCE CALL SJI President & COO, Edward J.
