STAMPS.COM REPORTS SECOND QUARTER 1999 FINANCIAL RESULTS

SANTA MONICA, CA–July 21, 1999–Stamps.com, the innovator of Postage ServerTM technology for the delivery of postage over the Internet, today reported an operating loss of $6.1 million for the second quarter ended June 30, 1999.

Net loss applicable to common shareholders was $5.7 million, or $0.66 per share, based on the weighted average number of 8.7 million common shares outstanding. Assuming the conversion of preferred stock at the respective dates of issuance, net loss would have been $0.19 per share, based on the weighted average number of 30.1 million common shares outstanding.
