Baltimore Technologies was a leading Irish internet security firm, with its headquarters in Dublin, Ireland. It was listed on the London Stock Exchange and was briefly part of the FTSE 100 Index during 2000. Fran Rooney was the CEO for a period in the 1990s. History The company was founded in 1976 by Michael Purser. Baltimore was acquired in 1996 by a team financed by Dermot Desmond and led by Fran Rooney. In December 1998 it was further acquired by Zergo Limited, a UK company listed on the London Stock Exchange. Post-acquisition, Zergo changed its name to Baltimore Technologies and Rooney was appointed CEO of the merged company. Under Rooney's leadership, Baltimore expanded rapidly, both through organic growth and by a series of high-profile acquisitions. In 1999 the company was listed on NASDAQ and the share price soared in value during the internet boom as its digital certificate business was seen as a vital tool to enable e-Commerce. The company showed considerable growth in both sales and market capitalisation, becoming a FTSE 100 firm with a market capitalization of over US$13 billion. However, following the stock market crash of March 2000, its share price fell. Rooney resigned as CEO in July 2001 and a bidding war for the firm ensued. Bijan Khezri, a former director of Baltimore Technologies in charge of capital markets finance, who had left the company over disagreements with Rooney in 2000, was appointed CEO. The new management team sold off the different business units in a series of demergers and by December 2003, following the sale of the PKI business to Betrusted and the authentication business to Hewlett Packard, the company was left a cash shell. In March 2004 the board announced its intention to move into the clean energy business. The plan was abandoned in June 2004 when vulture fund Acquisitor Holdings of Bermuda acquired sufficient shares to take control of the cash. In February 2005 Acquisitor delisted Baltimore from the London Stock Exchange and the various parties within Acquisitor split. The company listed on the Alternative Investment Market at the end of February 2006 under the symbol BLM. In May 2006, the company released an AGM statement which described its strategy as "becoming a financial services business concentrating on those specialist areas of the market where we have the skills and track record to obtain an operational multiple on the valuation of our shares."
