Film studio Pinewood Shepperton saw profit before tax improve by almost a third last year and has rewarded shareholders with a hike in the full year dividend to 3.60p from 3.45p.The company, which came under fire last year from activist shareholder Crystal Amber for underperformance, saw revenue increase by 8% to £43.4m in 2010 from £40.3m in 2009, largely as a result of film revenues burgeoning 28% to £29.1m from £22.6m as films such as Harry Potter and the Deathly Hallows and the Hammer horror picture The Woman In Black did some of their shooting at the company's studios. Earnings before interest, tax, depreciation and amortisation improved by 13% to £12.8m from £11.4m while profit before tax jumped 31% to £5.8m from £4.5m the year before."Pinewood has shown significant growth in all of the key metrics that measure the performance of the business. We have grown the top line by winning big budget international films which have been attracted to Pinewood by the superior quality of our assets and the range of services that we can offer," said chief executive Ivan Dunleavy. "Our television business continued to perform well at the top end of a difficult broadcast market," Dunleavy added. Television revenues dipped, as expected, to £8.2m from £11.3m in 2009, as both BBC and ITV produced more programmes in-house. Media Park revenues were down a tad at £6.2m from £6.3m in 2009. The Media Park offers a variety of complementary services for film and television productions using the company's studios.Net debt at the end of 2010 was down to £42.7m from £46.1m at the end of 2009, reflecting improved trading.
