Profitability to Accelerate Sequentially in Q2 and Second Half of 2011 as Accounts Scale

WALTHAM, Mass. – May 09, 2011 — Lionbridge Technologies, Inc. (Nasdaq: LIOX) today announced financial results for the quarter ended March 31, 2011. Financial highlights for the quarter include:

The Company recently announced general availability of GeoFluent™, a SaaS-based, customizable, real-time automated translation technology that instantly translates content and communications into multiple languages.  GeoFluent is based on IBM’s machine translation engine and is the result of a technology partnership between Lionbridge and IBM. Lionbridge has secured three prominent beta clients for GeoFluent and expects strong market demand for customizable, cost-effective, instantaneous translation of enterprise content that is not currently translated using traditional translation methods such as chat sessions, user generated Web content and Web sites.

Lionbridge also recently announced that it has secured new, multi-year, multi-million dollar relationships with leading organizations in the aerospace, media, mobile and services industries and has successfully expanded several existing client programs. In addition to these new programs, Lionbridge was also recently awarded a master services agreement with a large US retailer to become the client’s sole provider of translation and a two year contract with a sales and marketing services company. Lionbridge expects these programs to generate at least one million annually.

Based on strong revenue pipeline, the Company estimates its second quarter revenue will be $108 to $112 million.  The Company also reiterated its full year revenue guidance of 5-10% year-on-year growth.

“We are transitioning our business from revenue stability to revenue growth. It is heartening to see our second quarter revenue ramp ahead of plan. Our recent investments in sales and marketing are yielding positive results. We are increasing our win rates and securing new contracts with clients across vertical markets. We are expanding recent wins into multi-million dollar accounts,” said Rory Cowan, CEO, Lionbridge. “As we indicated, we expect revenue and profits to accelerate sequentially in the second quarter and the second half as we scale these new client programs and benefit from stronger product release cycle from major accounts. Our clients are investing in the future with product upgrades and new releases. With this positive revenue momentum from new and existing accounts we expect a strong 2011.”
