17 March 2021 | 07:36am StockMarketWire.com - Education software provider Tribal swung to a full-year profit on lower one-off costs, though its underlying earnings fell on lower sales. Pre-tax profit for the year through December amounted to £8.5 million, compared to a year-on-year loss of £2.9 million owing to the cost of a 'platform dispute'. Revenue fell 6.6% to £782 million and adjusted operating profit fell 3.2% to £14.9 million. Tribal declared a final dividend of 1.2p, in addition to a previous one-off interim dividend of 1.1p, which replaced the cancelled 2019 proposed final dividend. 'We have entered the current financial year with increased levels of revenue visibility,' chief executive Mark Pickett said.
