EMC Named One of America's Five Best-Performing Companies by Two Leading Business Publications.

HOPKINTON, Mass.--(BUSINESS WIRE)--March 22, 1999--

First-Ever Barron's 500 and

Annual Business Week 50 Each Rank EMC Near Top;

More Than 90% Of Top Companies Listed Are EMC Customers

EMC Corporation, the world's leading provider of enterprise storage systems, software and services, is among America's five top-performing companies, according to two separate, newly published studies by leading business publications.

In the first-ever Barron's 500, EMC is ranked fourth on what Barron's calls "a unique ranking of America's best companies for investors." In its March 22 issue, Barron's lists the 500 largest publicly traded U.S. companies in terms of revenues, and ranks them according to their stock-market returns and profitability. The top five includes America Online (1), Dell Computer (2), Best Buy (3), EMC (4), and Apple Computer (5).

In the third annual Business Week 50, published in the March 29 issue, EMC rose to the #5 position from #8 last year. In Business Week's exclusive ranking of the top overall performers among all companies in the Standard & Poor's 500 stock index, EMC is one of only four companies earning "straight A's" in all eight categories (1-year and 3-year total shareholder return, 1-year and 3-year sales growth, 1-year and 3-year profit growth, net profit margin, and return on equity). EMC is one of only 12 companies to be named to the Business Week 50 for all three years of the list's existence, and one of only five to make the top 20 each year.

Michael C. Ruettgers, EMC President and CEO, said, "The first thing I think of when I see lists like the Barron's 500 and the Business Week 50 is our customers. Our ranking in these prestigious lists is a result of our customers' strategic reliance on information and their adoption of EMC Enterprise Storage as the core of their information infrastructures. The most gratifying part of this honor for EMC is the fact that 46 of the top 50 Barron's 500 companies and 45 of the Business Week 50 companies are our customers - proof that industry leaders in every sector understand the business impact of managing and protecting their information assets by investing in the best technology solutions available."

Describing EMC, Barron's reported, "EMC is now the hands-down world leader in data storage: assembling and selling the hardware and software that computers of all types and sizes use to store information, and then retrieve it time and again on demand . . . The boom in cyberspace has been a bonanza with every e-commerce sale - indeed every mouse click on a Web page - creating valuable new information that has to be stored."

Information technology companies also dominate the upper echelon of the Business Week 50, capturing five of the top seven positions in the new rankings. Microsoft (1) and Dell Computer (2) lead the list for the second straight year, with Oracle (4), EMC (5) and America Online (7) also in the top 10. Other IT providers include Cisco Systems (14), BMC Software (22), Sun Microsystems (23), Gateway (24), and Intel (40).

"The technology that is getting the most attention, of course, is the Internet," reports Business Week. "And the explosion of Net-based business is found throughout the BW 50. Of the 11 tech companies on the list, almost all have some significant Internet business. Microsoft sells the software that lets you access it, EMC sells the devices that store the Internet's lifeblood data, and No. 14 Cisco Systems supplies much of the network equipment itself."

The magazine reported that last year's Business Week 50 companies returned an average of 32% to shareholders over the 52 weeks ended March 12, 1999, compared with the 21% gained by the broader S&P 500 and 15% gained by the Dow Jones Industrial Average over the same period. For the second year in a row, the magazine singled out EMC as the second-best performing stock among the Business Week 50 over the last 12 months, with an increase of 199%. According to Business Week, EMC's performance is due to its position "in the sizzling market for the hardware and software that allows companies to store all the data, Web pages, and other information being churned out in the Internet Age."
