Like-for-like sales at Inventive Leisure's Revolution vodka bars have plunged almost 15% in the past three weeks under the impact of "intense' High Street discounting, leading the company to warn that profits for the year could be "significantly" below market expectations. Inventive's chief executive, Roy Ellis, said this morning that in the short term the company would be looking at its own policy of not discounting drinks prices, after a fall in like-for-like sales of 14.6% in the three weeks to March 13 brought the average sales decline in the second half so far to 10.4%. "Should this very recent trend continue, we believe that current year profits would be likely to fall significantly below current market expectations," Ellis said. In the first half of the year to December 27, group turnover rose by 17% to £20.4m, with ebitda up by 20% to £3.3m and profit before tax up by 5% to £1.5m. Adjusted profit before tax, after disposals and exceptionals, rose by 3%. ROCE for the first half of the year,measured as operating profit less interest divided by shareholders' funds, fell to 9.3% from 10.1% in 2003. Six new bars opened in the period, bringing the Revolution estate to 42. Average gross weekly revenue for the new bars was £32,700, 17% up on the Revolution average for the last financial year.
