Shares in E2V plunged after the electrical component maker posted a 13% drop in annual pre-tax profit as markets became increasingly challenging in the fourth quarter. Adjusted profit before tax fell to £20.4m for the year ended 31 March 2009. Sales were up 14%, due to the benefit of acquisition and FX movements to £233.2m. Commenting on the results chief executive Keith Attwood said, "e2v faced increasingly challenging markets in the final quarter of the year and the group responded with a range of actions delivering a creditable trading performance." Looking forward, conditions remain tough in the first half of the new financial year, Attwood added, "though the stronger than normal order book, along with a good order pipeline, is encouraging for the second half."Content management and translation software company SDL said its software has been selected by US technology giant Hewlett-Packard (HP) for use in its corporate web sites.
