InfoSpace Board Renews Authorization of Stock Repurchase Program of Up to $100 Million

BELLEVUE, Wash. (May 30, 2006) – InfoSpace, Inc. (NASDAQ: INSP) today announced that its Board of Directors has authorized a repurchase of up to $100 million of the Company’s outstanding shares of common stock over the next twelve months. This is in addition to the approximately $70 million or 2.6 million shares purchased under the previous program.

“We believe that at current levels, InfoSpace’s stock price remains undervalued and does not reflect the strength of the business or our ability to generate long-term value for our shareholders,” said Jim Voelker, chairman and chief executive officer of InfoSpace, Inc. “Our strong cash position and operating cash-flow provide us with the flexibility to repurchase shares while continuing to invest in our future.”

Subject to applicable securities laws, the shares may be repurchased from time to time in the open market or in privately negotiated transactions. Such purchases will be at times and in amounts as the Company deems appropriate, based on factors such as market conditions, legal requirements and other corporate considerations. The Company’s Board of Directors has also authorized that purchases may be made under Rule 10b5-1 of the Securities Exchange Act of 1934. A Rule 10b5-1 plan allows InfoSpace to repurchase its shares during periods when the Company would normally not be active in the market due to its own internal trading blackout periods.

Cash, cash equivalents, and marketable investments at March 31, 2006 totaled approximately $395.6 million, and the Company had no debt obligations. Additionally, InfoSpace had approximately 31.2 million shares of common stock outstanding as of March 31, 2006.
