Lightbridge Announces Revised Fourth Quarter and Year End 2004 Financial Results in Light of Recent Lease Accounting Clarification by SEC

BURLINGTON, Mass.—(BUSINESS WIRE)—March 17, 2005—Lightbridge, Inc. (NASDAQ:LTBG) Lightbridge, Inc. (NASDAQ:LTBG), a leading analytics, decisioning and e-commerce company, today reported an adjustment to its previously announced unaudited financial results for the fourth quarter and full year 2004, resulting from a change in accounting for the Company's operating leases.

In light of views expressed by the Securities and Exchange Commission on February 7, 2005, with respect to accounting for operating leases, the Company recorded a fourth quarter 2004 adjustment related to tenant improvement allowances and rent holidays provided by landlords. The audited financial statements contained in the Company's Form 10-K for the year ended December 31, 2004, which the Company filed today, reflect the change in accounting treatment.

The adjustment resulted in a cumulative $0.6 million increase in the net loss attributable to prior interim periods in 2004. The impact on the Company's December 31, 2004 consolidated balance sheet was an increase in property and equipment of approximately $3.2 million, and an increase in deferred rent of approximately $3.6 million. The impact on the Company's consolidated statements of cash flows was to increase both "net cash provided by operating activities" and "net cash used in investing activities" by equal amounts of approximately $3.5 million for the fiscal year ended December 31, 2004. The Company believes the effect of the adjustment is not material to the financial statements for the year ended December 31, 2004.
