STAMPS.COM ANNOUNCES FIRST QUARTER 2006 RESULTS

Q1 Revenue Up 74% Versus Last Year

LOS ANGELES – April 25, 2006 – Stamps.com® Inc. (Nasdaq: STMP) today announced results for the first quarter ended March 31, 2006.

For the first quarter:

  • Total revenue was $20.5 million, an increase of 74% versus the same quarter last year.
  • Total core business revenue (excluding PhotoStamps) was $16.7 million, an increase of 41% for that business versus the same quarter last year.
  • Core business subscription revenue was $13.5 million and online store revenue was $2.4 million, up 48% and 27%, respectively, versus the same quarter last year. Insurance fees, licensing fees, and other revenue contributed an additional $0.8 million.
  • Approximately 210 thousand sheets of PhotoStamps® were shipped, resulting in $3.9 million total first quarter PhotoStamps revenue (there was no PhotoStamps revenue in the same quarter last year prior to the start of the second USPS custom postage market test).
  • Total GAAP gross margin was 71% versus 73% in the same quarter last year, the decrease being attributed primarily to the inclusion of PhotoStamps revenue, which was at 37% gross margin, in the first quarter this year.
  • Core business GAAP gross margin was 79% versus 73% in the same quarter last year.
  • GAAP net income was $3.36 million, or $0.14 per fully diluted share, including approximately $795 thousand of stock-based compensation expense related to the Company’s adoption of FASB Statement 123R that began this quarter.
  • Excluding the FASB Statement 123R expenses, non-GAAP net income per fully diluted share was $0.17, an increase of 143% versus 2005 first quarter GAAP net income per share of $0.07, which also did not include any 123R-related expenses.

“We are pleased with our continued revenue and earnings growth,” said Stamps.com president and CEO Ken McBride. “Our core PC Postage business showed very strong revenue and earnings growth during the first quarter, and PhotoStamps sales continued to be strong despite the expected first quarter seasonal slowdown following the holiday period. “

Stamps.com reported 2006 first quarter GAAP net income of $3.36 million, including approximately $795 thousand, or approximately $0.03 per fully diluted share, of stock-based compensation expense related to the Company’s adoption of FASB Statement 123R that began this quarter. On a per share basis, total 2006 first quarter GAAP net income was $0.14 based on fully diluted shares outstanding of 24.4 million. The approximately $795 thousand stock-based compensation expense was allocated among cost of sales, sales and marketing, research and development, and general and administrative categories, based on individual employee costs and positions, as shown in the following table.

Excluding the FASB Statement 123R expense, 2006 first quarter non-GAAP net income was $4.15 million. On a per share basis, 2006 first quarter non-GAAP net income per fully diluted share was $0.17 based on fully diluted shares outstanding of 24.4 million. In the first quarter of last year, which also did not include any 123R-related expenses, net income per fully diluted share was $0.07 based on fully diluted shares outstanding of 23.4 million. Thus, the year over year increase from 2005 first quarter GAAP earnings per share versus 2006 first quarter non-GAAP earnings per share was 143%.

On May 17, 2005, Stamps.com began a second year-long market test of PhotoStamps, the popular form of postage that allows customers to turn digital photos, designs or images into valid U.S. postage. During the first quarter, approximately 210 thousand sheets, or more than four million individual PhotoStamps, were shipped to customers. Since the beginning of the second market test in May 2005, more than 14.5 million PhotoStamps have been shipped to customers.

Stamps.com currently expects a new phase for customized postage to begin this month or next month, prior to the end of the second phase of the market test on May 16. In addition, beginning with the new phase, the U.S. Postal Service is expected to lift the restriction on business advertising on customized postage, which has been in place since the second market test began in May 2005. Stamps.com plans to participate in the new phase with its PhotoStamps® product, and will begin marketing PhotoStamps for business use as soon as the business advertising restriction is lifted.

Stamps.com currently expects total fiscal 2006 revenue to be $82 to $90 million. Fiscal 2006 GAAP net income per share is expected to be $0.54 to $0.62, including approximately $3.3 million of stock-based compensation expense related to the Company’s adoption of FASB Statement 123R that began in 2006. Excluding the FASB Statement 123R expenses, non-GAAP fiscal 2006 net income per fully diluted share is expected to be $0.67 to $0.75.

The Company plans to discuss its business outlook during the conference call. Following the conclusion of the Web cast, a replay of the call will be available at the same website.
