Shares in Internet security company Baltimore fell to a two and a half year low in London today, down 6.5% to 36p sterling by mid-morning.
Dealers said the drop was a response to a clarification from the company on Friday following a statement the previous day which said six European banks had chosen its products.
The update said the contracts had been signed over a period of time and did not represent a material increase in licence revenue for the company.
Last month, Baltimore announced that it would cut 250 jobs and forecast only 'modest' revenue growth.
