EXHIBIT INDEX Exhibits 99.1--Press Release Exhibit 99.1 EASTERN CONSIDERING STRATEGIC ALTERNATIVES WESTON, Massachusetts -- August 16, 1999 -- Eastern Enterprises (NYSE: EFU) announced today that it is beginning the process of evaluating a number of strategic and financial alternatives to enhance shareholder value. The process will include an assessment of its current strategy of consolidating New England gas distribution utilities, as well as consideration of share repurchases and/or other strategic transactions, including joint ventures or sale of all or a portion of the Company. J. Atwood Ives, Eastern's chairman and chief executive officer, comments, "We have made substantial progress in achieving our strategic objective of consolidating New England gas distribution companies for the benefit of both our customers and shareholders. Upon completion of the pending mergers with Colonial Gas, expected to close at the end of August, and EnergyNorth, expected to close mid-2000, Eastern will own and operate, in the aggregate, the largest natural gas distribution company in New England serving over 800,000 customers throughout Massachusetts and New Hampshire. It also owns and operates the nation's second largest inland marine transportation company and several non-regulated businesses that complement its LDC operations. As a result of the dramatic changes taking place within the utility industry, Eastern's Board of Trustees and management believe now is a prudent time to undertake a review of all of Eastern's options." The Company has retained Salomon Smith Barney to assist Eastern's Board of Trustees and management in its review of strategic alternatives. Eastern Enterprises owns and operates Boston Gas Company, Essex Gas Company, Midland Enterprises Inc. and ServicEdge Partners, Inc. Upon completion of the pending mergers with Colonial Gas and EnergyNorth, Eastern will serve over 800,000 natural gas customers in Massachusetts and New Hampshire. Midland, headquartered in Cincinnati, Ohio, is the leading carrier of coal and a major carrier of other dry bulk cargoes on the nation's inland waterways. ServicEdge is the largest unregulated provider of residential HVAC equipment installation and service to customers in Massachusetts. This release and other company reports and statements issued or made from time to time contain certain "forward-looking statements" concerning projected future financial performance, expected plans or future operations. Eastern cautions that actual results and developments may differ materially from such projections or expectations. Investors should be aware of important factors that could cause actual results to differ materially from the forward-looking projections or expectations. These factors include, but are not limited to: o the effect of pending mergers on earnings and cash flow and of adopting any new strategic initiatives, o Eastern's ability successfully to integrate its new gas distribution operations, o temperatures above or below normal in eastern Massachusetts, o changes in market conditions for barge transportation, o adverse weather and operating conditions on the inland waterways, o uncertainties regarding the ultimate profitability of ServicEdge, o the timetable and cost for completion of Eastern's year 2000 plans, o the impact of third parties' year 2000 issues, o changes in economic conditions, including interest rates and the value of the dollar versus other currencies, o regulatory and court decisions, and o developments with respect to Eastern's previously-disclosed environmental liabilities. Most of these factors are difficult to accurately predict and many are beyond the control of the Company. - ------------------------------------------------------------------------------- Eastern Enterprises' press releases are available via fax by calling, toll-free, 1-800-311-4607 or on the Internet at http://www.efu.com. - -------------------------------------------------------------------------------
