Mears said it had restructured the senior management and social housing operations to stem losses and put Morrison on track to deliver break-even results at half-year.
In the period leading up to completion of the acquisition several Morrison contracts were encountering significant service delivery failures and poor client relationships.
Mears Chairman Bob Holt said since taking the firm over it had stemmed the exodus of clients and prevented further contract losses.
He said: “The integration is substantially complete. The speed of this turnaround is ahead of our original expectation.”
Mears continues to defy reports of tightening margins in the sector and said it was on track to deliver management expectations at the half-year.
Since the start of the year the firm has secured a new contract worth £125m.
It aded it was seeing stronger spends from existing clients and now had 95% visibility of the forecast £915m sales forecast for 2013.
The order book stands at £3.8bn and the bid pipeline remains at £3.0bn.
