(Sharecast News) - Rolls-Royce chief executive Warren East purchased 9,488 ordinary shares in the FTSE 100-listed engine manufacturer on Wednesday.East, who took over from previous CEO John Rishton back in 2015, acquired the shares at an average price of 790.40p per share, for a total value of £74,993.15.Rolls-Royce backed its full-year guidance back in October as it said it expects to deliver fewer Trent 7000 engines in the fourth quarter than originally planned.Pinning the blame on "early stage production ramp-up challenges", the aerospace and defence giant said it is likely to fall short of its prior engine delivery projection of around 550 large engine deliveries for this year and is now expecting to deliver 500 engines."While we regret the impact this will have on our customers, we are today re-iterating our financial guidance for 2018 profit and free cash flow as provided at the time of our interim results in August 2018," it said.As of 1650 GMT, Rolls shares had climbed 3.75% to 814.40p.Top Director BuysRolls-royce Holdings (RR.)Director name: East,WarrenAmount purchased: 9,488 @ 790.40pValue: £74,993.15Eland Oil & Gas (ELA)Director name: Bain,RonaldAmount purchased: 17,500 @ 109.25pValue: £19,118.75Proteome Sciences (PRM)Director name: Diggle ,Martin Amount purchased: 500,000 @ 3.42pValue: £17,100.00Aquis Exchange (AQX)Director name: Haynes,Alasdair Frederick SetonAmount purchased: 1,500 @ 600.00pValue: £9,000.00Aquis Exchange (AQX)Director name: Clelland,Jonathan CharlesAmount purchased: 1,500 @ 600.00pValue: £9,000.00Minds + Machines Group Limited (di) (MMX)Director name: Turcan,Henry Amount purchased: 2,100,000 @ 0.06pValue: £1,260.00Minds + Machines Group Limited (di) (MMX)Director name: Turcan,Henry Amount purchased: 1,500,000 @ 0.06pValue: £900.00Minds + Machines Group Limited (di) (MMX)Director name: Turcan,Henry Amount purchased: 180,000 @ 0.06pValue: £108.00Top Director SellsAlpha Real Trust Ltd.
