EXHIBIT 99.1 CONFIDENTIAL EARTHLINK AND MINDSPRING ANNOUNCE STRATEGIC MERGER EARTHLINK AND MINDSPRING COMBINE TO CREATE THE NATION'S SECOND LARGEST INTERNET ACCESS PROVIDER NEW YORK, September 23, 1999 - EarthLink (NASDAQ: ELNK) and MindSpring (NASDAQ: MSPG) jointly announced today that they have signed a definitive merger agreement that will create the nation's second largest provider of Internet access, with an estimated combined base of over three million members upon completion of the deal. In the merger, MindSpring and EarthLink will both merge into a newly formed public company, with MindSpring stockholders receiving one share of the new company stock for each share of MindSpring stock and EarthLink stockholders receiving 1.615 shares of the new company stock in exchange for each share of EarthLink stock. The combined company will be known as EarthLink and will trade under the Nasdaq symbol "ELNK." Subject to several conditions, including regulatory approvals, approval by both companies' shareholders, and certain third party consents the transaction is expected to close in the first quarter 2000. Based on the closing price of both companies' stock on Wednesday, September 22, combined market capitalization of the new company would be over $3 billion. Based on results for the quarter ending June 30, 1999, the merged company would have revenues of nearly $650 million annualized. Also as of June 30, 1999, the new company would have a combined cash balance of --more-- EARTHLINK AND MINDSPRING MERGE PAGE 2 more than $500 million, which is adjusted for the anticipated redemption of all of MindSpring's currently outstanding 5% convertible subordinated debt. The merger marks a culmination of aggressive growth strategies pursued independently by both EarthLink and MindSpring over the past five years. By combining their businesses, strong marketing channels, award-winning customer service and acquisition expertise, the merged company should surpass all other national ISPs by establishing itself as the clear alternative to America Online. In addition, a recent JD Power and Associates study ranked MindSpring and EarthLink numbers one and two, respectively, in overall customer satisfaction among the largest National Internet Service Providers. The new company will be led by executives from both EarthLink and MindSpring. In the new company, Charles Brewer, MindSpring's founder, chairman and CEO will be chairman; Charles "Garry" Betty, EarthLink's president, CEO will be CEO; Mike McQuary, MindSpring's president, chief operating officer will be president; and Sky Dayton, EarthLink's founder and chairman will be a director in the new company. Betty and McQuary will also serve on the Board of Directors. "I believe this marriage of equals will position the new company as the clear leader in the Internet access arena," said Betty. "By leveraging the synergies between our operations, marketing channels and member service philosophies, we will have built a solid platform to service our current members and, at the same time, accelerate our aggressive growth strategy." "Sky and I both founded our companies after our first frustrating attempts to get on the Internet," said Brewer. "We created our companies with a deliberate focus on providing our members with superior service. So it's no accident that both EarthLink and MindSpring have consistently been recognized as the two leading ISPs in customer service and satisfaction. Together, we will continue delivering the same award-winning service and support that our members expect." "Five years ago, Charles and I were among the few visionaries who saw the potential in the Internet to redefine the way people communicate," said Dayton. "In many ways, MindSpring and EarthLink's vision, philosophy and growth have been a mirror image of each other since we started. But with more than 70 percent of US households still not connected to the Internet, we both realize we are still facing a market in its infancy. This merger combines two companies who share a vision, and it gives us the tools to bring Internet service to the masses." "This unique partnership literally brings together some of the best minds in the Internet industry," said McQuary. "We believe that the exceptional pool of talent and resources from both sides will propel the new company to new heights in the rapidly growing Internet space."
