Economic Earnings Bridge | Q1’18 to Q1’19 • Utility variance primarily reflects partial year ownership of ETG and ELK, as well as 1.9% SJG customer growth and infrastructure investment, offset by higher operating costs • Midstream variance reflects AFUDC for PennEast Pipeline project • Non-Utility variance primarily reflects lower wholesale margins on daily energy trading activities tied to tighter spreads, lack of sustained cold weather and associated volatility and new pipeline operating rules that limited asset optimization • Other variance reflects acquisition-related financing costs net of debt repayments from asset sales 5

Regulatory Initiatives | ETG Infrastructure Modernization ➢ Infrastructure Investment Program (IIP) Elizabethtown Gas (ETG) Projected Pipeline Replacement • Consistent with acquisition approval, SJI was required to develop a 500 plan, in concert with NJBPU Staff, to address remaining aging 428 infrastructure at ETG 400 366 304 • On October 29, 2018 ETG filed a $518M, five-year infrastructure 300 240 replacement program proposal with the NJBPU 200 175 • IIP design includes request for timely recovery of investment Miles Pipe 64 62 62 64 65 through a separate rider recovery mechanism 100 ➢ 0 Program Details 2018E 2019E 2020E 2021E 2022E Vintage Pipe Replaced Vintage Pipe Remaining • Retirement of 364 miles of vintage main including cast-iron, unprotected and bare steel, ductile iron, copper and vintage plastic • Installation of 309 miles of polyethylene plastic main ELIZABETHTOWN GAS (ETG) • 41K new services REPLACEMENT MILES BY PIPE MATERIAL • 38K excess flow valves Iron, 9 Bare Steel, 15 • Movement of 44K inside meters to outside with house regulators Low Pressure, 96 • Conversion of five remaining master-metered apartment complexes to individually-metered units. New main, service lines and ~1,300 individual meters would be installed Copper, 1 ➢ We've begun settlement discussions and expect a final decision from the NJBPU in 2019 Cast Iron, 372 6

Regulatory Initiatives | ETG Base Rate Case Delivering safe, reliable, affordable natural gas service requires investments to replace aging mains, support compliance with State and Federal system integrity and safety regulations, and implement measures that improve the overall ETG customer experience ➢ Request Details • In April, ETG filed a petition with the NJBPU requesting a revenue increase of approximately $65 million to recognize the infrastructure investments made to maintain the safety and reliability of its natural gas delivery system • Request includes approximately $346 million net plant additions not included in rates established in ETG’s last base rate case (i.e., plant additions associated with the period October 1, 2017 through February 29, 2020) • Assumes an overall rate of return of 7.6%, a return on equity of 10.4% and a 52.5% equity ratio • Test Year September 1, 2018 through August 31, 2019 ➢ Notable Considerations • Proposed rates will still result in a 10.1% lower gas bill for a residential heat customer compared to rates in effect a decade ago • As part of the acquisition, ETG customers received bill credits totaling $15 million in 2018 • Currently, average annual natural gas bills for ETG customers are among the lowest in the state • For three years in a row, ETG has ranked highest in customer satisfaction for residential gas service among east midsize utilities by J.D. Power and Associates ➢ Settlement discussions expected to begin later this year followed by a final order, in line with precedent from prior cases 7

Financial Guidance | 2019 Reaffirmed ❖ SJI reaffirms its expectation for 2019 economic earnings in the range of $98 million to $107 million, or $1.05 to $1.15 per diluted share. ❖ Economic earnings guidance primarily reflects 1) regulated operations that represent 80-85% of economic earnings excluding acquisition-related interest costs, 2) costs associated with the transition services agreement we have with Southern which we intend to exit by early 2020, 3) financing and operational requirements associated with our ETG/ELK acquisitions and divestitures of non-core nonregulated businesses and 4) timing associated with the execution and implementation of our regulatory strategy. ❖ Capital expenditures are expected to be approximately $530 million in 2019. Investments in our regulated businesses are expected to represent more than 97 percent of capital expenditures. Following our equity forward draw in January, SJI does not anticipate any additional equity issuances in 2019. 8

Economic Earnings Bridge | 2018 to 2019 Midpoints $102 • Utility variance reflects full-year benefit of ETG and ELK operations, customer growth, infrastructure investment, and benefits from ongoing business transformation initiatives • Midstream variance reflects AFUDC for PennEast Pipeline project • Non-Utility variance reflects additional fuel management contracts, tighter wholesale spreads, legacy marketing contract headwinds and non-core asset divestitures • Other variance reflects full-year impact of acquisition financing costs, net of anticipated debt repayments from asset sales 9

Financial Guidance | 2020 ❖ SJI expects 2020 economic earnings in the range of $147 million to $160 million, or $1.53 to $1.67 per diluted share. ❖ Economic earnings guidance primarily reflects 1) regulated operations that represent approximately 80% of earnings excluding acquisition-related interest costs, 2) accelerated utility customer growth and infrastructure replacement at both ETG and SJG, 3) execution of our regulatory strategy including base utility investment, 4) increased contribution from fuel management and a reshaped wholesale portfolio, and 5) lower operating costs driven by our business transformation activities. ❖ Capital expenditures are expected to be approximately $565 million in 2020. Investments in our regulated businesses are again expected to represent more than 97 percent of capital expenditures, with an equity issuance planned to support a utility redundancy project. 10

Non-GAAP Financial Measures Management uses the non-generally accepted accounting principles (non-GAAP) financial measures of Economic Earnings and Economic Earnings per share when evaluating its results of operations. These non-GAAP financial measures should not be considered as an alternative to GAAP measures, such as net income, operating income, earnings per share from continuing operations or any other GAAP measure of liquidity or financial performance. Economic Earnings is a significant performance metric used by our management to indicate the amount and timing of income from continuing operations that we expect to earn after taking into account the impact of derivative instruments on the related transactions, those transactions or contractual arrangements where the true economic impact will be realized primarily in a future period or was realized in a previous period, and other events that management believes make period to period comparisons of SJI's operations difficult or potentially confusing. Specifically regarding derivatives, we believe that this financial measure indicates to investors the profitability of the entire derivative-related transaction and not just the portion that is subject to mark-to-market valuation under GAAP. We believe that considering only the change in market value on the derivative side of the transaction can produce a false sense as to the ultimate profitability of the total transaction as no change in value is reflected for the non- derivative portion of the transaction. We define Economic Earnings as: Income from continuing operations, (i) less the change in unrealized gains and plus the change in unrealized losses on all derivative transactions; (ii) less realized gains and plus realized losses on all commodity derivative transactions attributed to expected purchases of gas in storage to match the recognition of these gains and losses with the recognition of the related cost of the gas in storage in the period of withdrawal; (iii) less the impact of transactions or contractual arrangements where the true economic impact will be realized in a future period, along with other events that management believes make period to period comparisons of SJI's operations difficult or potentially confusing. Please refer to our annual report on form 10-k and other SEC filings where the reconciliations to GAAP earnings can be found. 19
