InfoSpace Acquires Mercantila’s e-Commerce Business

Acquisition marks InfoSpace’s entrance into new, specialty e-commerce channel

BELLEVUE, Wash., May 11, 2010 (BUSINESS WIRE) — InfoSpace, Inc. (NASDAQ:INSP) a developer of metasearch products, today announced that it has purchased assets from Mercantila, Inc., a privately-held specialty online retailer, in a move that will diversify its business model. The transaction closed on May 10, 2010, and includes a purchase price of $8 million in cash, plus the assumption of certain liabilities, not to exceed $5.9 million.

“Mercantila will provide InfoSpace with a foundational technology platform and represents the first step in our differentiated
e-commerce strategy,” said William J. Lansing, chief executive officer of InfoSpace. “Through organic growth and development of Mercantila’s current platform, along with other acquisitions, we intend to become a strong e-commerce player. We believe that
e-commerce represents an attractive segment in which InfoSpace can build a profitable business, accelerate the monetization of our NOLs, and create additional shareholder value.”

The acquisition is part of InfoSpace’s strategy to expand its online audience beyond search. InfoSpace will build on Mercantila’s strong drop-ship supplier platform to support InfoSpace’s low asset intensive approach to e-commerce. Mercantila owns more than 200 specialty stores on the Web under a range of domain names and has partnered with more than 1,000 fulfillment partners to supply its products.

Mercantila will operate as a wholly-owned subsidiary, under the leadership of Nikhil Behl, its former chief merchandising officer and newly appointed chief executive officer of the subsidiary.

“This is an excellent transaction that creates greater opportunity for both of our companies,” said Mr. Behl. “Our strength in drop-ship e-commerce coupled with InfoSpace’s capital and technical talent is a formula for rapid expansion and growth.”

Union Square Advisors LLC acted as the financial advisor to InfoSpace on the transaction.

Preliminary Adjusted EBITDA⁽¹⁾ Reconciliation for Forward-Looking Guidance

(Amounts in thousands)

	Ranges for the three months ending
	June 30, 2010
Net income	$	1,000		$	2,000
Depreciation and amortization of intangible assets		2,300			2,300
Stock-based compensation		3,800			3,800
Other income, net (2)		(100	)		(100	)
Income tax expense		2,000			2,000
Adjusted EBITDA	$	9,000		$	10,000

⁽¹⁾ InfoSpace’s Adjusted EBITDA is calculated by adjusting net income determined in accordance with generally accepted accounting principles (“GAAP”) to exclude the effects of income taxes, depreciation, amortization of intangible assets, stock-based compensation expense, and other income, net (which includes such items as interest income, foreign currency gains or losses, and gains or losses from the disposal of assets), as detailed above. InfoSpace’s management believes that Adjusted EBITDA provides meaningful supplemental information regarding the Company’s performance by excluding certain expenses and gains that management believes are not indicative of its core business operating results. InfoSpace uses this non-GAAP financial measure for internal management purposes, when publicly providing guidance on possible future results, and as a means to evaluate period-to-period comparisons. InfoSpace believes that Adjusted EBITDA is a common measure used by investors and analysts to evaluate its performance, that it provides a more complete understanding of the results of operations and trends affecting the Company’s business when viewed together with GAAP results, and that management and investors benefit from referring to this non-GAAP financial measure. Adjusted EBITDA should be evaluated in light of the Company’s financial results prepared in accordance with GAAP, and should be considered as a supplement to, and not as a substitute for or superior to, GAAP net income.

⁽²⁾ Other income, net, primarily consists of interest income, gains or losses from the disposal of assets, and foreign currency transaction gains or losses.
