AstraZeneca, one of the top ten UK companies by market value, releases fourth quarter and full year results on Thursday, when it will have to deliver on the increased profit expectations it announced at the end of October. Astra guided to mid to high single-digit sales growth at constant exchange rate for the full-year, and upgraded core earnings per share to $6.20-6.40 from $5.70-6.00 previously. It said the outlook for the rest of 2009 has been boosted by the withdrawal of generic products for Toprol-XL, additional orders for the H1N1 influenza vaccine, and the release of a provision within cost of sales that further benefited.Since then, there have been reports of governments cutting back on H1N1 influenza vaccine. AstraZeneca had $152m of swine flu nasal spray sales in the third quarter and had projected to make a further $300m from the vaccine in the fourth quarter.On the positive side, the fourth quarter saw the company come to an accommodation with Israel-based rival Teva Pharmaceuticals over the latter's generic version of Astra's Nexium ulcer capsules, and made regulatory progress with some of its drugs, including its bipolar disorder treatment Seroquel, which the US Food and Drug Administration approved for use in conjunction with antidepressants to treat major depressive disorder.Pay TV and Internet service provider British Sky Broadcating weathered the recession better than most, but it has been doing less well in the courts, after its latest appeal over the forced sale of most of its stake in ITV was rejected.Newspaper reports suggested the company may give up the legal battle, cut its losses and sell the shares soon, in order to end the long running saga and enable investors to focus on the merits of the company again.On the international scene, mobile phone giants Ericsson and Nokia both issue results next week. Though the two companies dominate the mobile phone market, investors will be less interested in how they have fared against each other and more concerned with their response to the growing threat from Apple and Google.Monday January 25INTERIMSCity of London Investment Group, FiltronicINTERIM DIVIDEND PAYMENT DATEHalfords Group, MS InternationalQUARTERLY PAYMENT DATEHenderson Global Property
