The firm, which posted a 114% surge in annual revenues on Friday, said the audit was "substantially complete" and that it did not expect any changes to the preliminary results. But after the company made a series of acquisitions last year, Alphawave - which trades as Alphawave Semi - said its auditor had requested more time to complete its internal oversight and assurance processes before issuing the formal audit opinion. As a result, publication of the audited numbers is now scheduled for 12 May, after the deadline imposed by City rules. It is therefore asking for its shares to be suspended from 2 May, with trading set to resume once the audited results are published. As at 1300 BST, shares in Alphawave had tumbled 17% to 99p. The update overshadowed otherwise strong results for the year 31 December alongside "record'" bookings in the current quarter. Annual total revenues came in at $192.4m, after Alphawave invested $439m cash in acquiring three companies: Precise-ITC, OpenFive and Banias Labs.
