This follows Reginald Gott's wife Alison's previous acquisition of 28,515 shares at 35.7p each.FinnCap analyst Dr Paul Cornelius met Filtronic's management yesterday and came away positive about the purchase of Isotek. He believes the base station technology developer could add 2p a share to Filtronic's earnings in the year to May 2012. He was also reassured that Filtronic is not too dependent on the UK defence market because of overseas demand for products. Pharma company Shire is falling back following the release of its second quarter figures even though it raised its full year earnings expectations. Total revenues climbed 35% to $849m in the three months to June 2010. Shire expects earnings for the full year of $4 per ADS (American Depositary Share), a 15% increase on 2009, and up from previous expectations of about $3.80. There are three ordinary shares to each ADS, so 2010 earnings per share should be around 84p.
