"Whilst the short term decline in licence [revenue] is disappointing it is not unusual given the level of change being undertaken," he added.
Having received the necessary regulatory sign-offs, Micro Focus expects the takeover of HPE Software to complete in September – a full year after the deal was first announced.
Micro Focus said it would convene a general meeting to request approval of the transaction shortly.
Shareholders will also be asked to rubber-stamp a £386mln return of cash – which equates to £1.61 a share.
At 8.30am the shares were down 311p at £23.28, valuing the business at £5.5bn.
