SDL is Promoted to FTSE All-Share Index

Maidenhead, UK - 19th December 2005

SDL plc, a leader in the emerging market for global information management (GIM) solutions, announced today its promotion to the FTSE All-Share Index. Organizations in the All-Share Index can benefit from increased trading volumes and inclusion in certain tracker funds, and with this promotion SDL anticipates increased press and analyst interest.

Commenting on the promotion, Mark Lancaster, Chairman and Chief Executive Officer of SDL, said today: “As well as marking another significant milestone for the company, SDL’s admission to the All-Share Index carries an important message about world business. Global organizations increasingly recognize that their continuing success demands that product, marketing and technical information are communicated in the native languages of their customers, and the promotion of the leading provider in this field to the All-Share Index is a signal of further maturation.”

Lancaster continued: “The increasingly widespread adoption of GIM solutions has contributed to over 500% revenue growth since SDL’s first Stock Exchange listing six years ago. Our strategy of investing in GIM technology and our creation of a global network of 50 offices in 30 countries has made us significantly more profitable than our competitors. I welcome the increased visibility amongst the investment community and look forward to increased trading volumes for SDL.”
