easyJet unveils its first-quarter results Thursday in the wake of news that its founder threatened to sell further shares if the airline places an order for more aircraft.Sir Stelios Haji-Ioannou voiced his concern over the company's expansion plans in an open letter published on Monday, accusing directors of "squandering" cash on new planes. He warned directors he would sell his 37% family stake in the budget carrier if they go ahead with the order. Analysts at Investec forecast passenger growth of 6.2% year-on-year to 13.7m and pegged revenue growth of 8.4% at £827.1m for the first quarter.However the broker reduced its recommendation from 'buy' to 'hold' on Monday, saying: "The stock was our key 2012 airlines pick, but the shares have outpaced the market and we now project a period of share price stability rather than material growth, coupled with uncertainty over the outcome of a major new aircraft order in 2013."In contrast, Morgan Stanley retained its 'overweight' stance on the stock on Wednesday, saying that it remains its "top pick in the European airline sector". The US broker's full-year profit before tax forecast of £356m is currently 13% ahead of consensus estimates.Shares fell 0.12% to 856.00p at 16:00 a day ahead of the results.Thursday January 24 INTERIM DIVIDEND PAYMENT DATE Dairy Crest Group, Tongaat-Hulett Ltd.
