Gavin Darby, the new Chief Executive Officer of Premier Foods, purchased 0.7m pounds-worth of shares on Thursday, the same day the debt-laden food manufacturer posted an increase full year underlying trading profit. The CEO, who was appointed to the role last month, bought 750,268 shares at 93.30p a time, his only holding in the group. The group said it expects to make progress in the year ahead, despite persistently challenging markets, after underlying trading profit, which excludes all disposals announced in 2011 and 2012, rose 10.6% to £123.4m. Premier Foods sold Sarson's vinegar and Branston pickle in 2012 to help reduce debts of £1.3bn. The owner of the Hovis, Mr Kipling and Loyd Grossman brands, said adjusted pre-tax profit from continuing operations rose to £85.2m in the year ended December 31st 2012 from £72.6m a year earlier. Annual sales fell 12.2% to £1.8bn. The company had an eventful 2012, including the surprise resignation of CEO Michael Clarke in January after just 18 months in the job. Darby said of the results: "It's important now to maintain continuity and focus on executing our existing strategies to build further momentum in Grocery while re-building value in Bread."
