Three companies have reported results, boosted by acquisitions.

Healthcare Locums saw turnover rise to £30.4m for the first half of the year, from £18.4m a year earlier. Pre-tax profit for the period was £19,000, compared with a loss of £1.19m for the same period a year ago. The company bought Medical Professionals, Social Work Professionals and BBL Medical during the period.

Kate Bleasdale, chief executive, says the period had “been one of intense activity marked by contract wins in excess of £35m".

Empresaria saw turnover rise to £33.9m, from £24.5m. Pre-tax profit rose to £606,000, from £508,000. Tony Martin, chairman (pictured), says: “Our strong growth through the first half has positioned us well for a positive second half, when we traditionally make the majority of our profit.”

The company said its UK operations “enjoyed strong organic growth” and contribution from the financial services and property services and construction sectors.

IT recruiter Networkers International reported increased turnover, following the reverse acquisition of Streetnames earlier this year.

The results represent those of Networkers International for the seven months to 30 June, plus those of Streetnames from 24 May to 30 June.

Turnover rose to £22m, from £15m. Pre-tax profit rose to £1.7m, from £1.3m.

Spencer Manuel, managing director, says: ”Reorganisation of the Group in the period has given a more focused and structured approach to not only winning new customers but also cementing existing ones.”

It said its emerging market activity continued to contribute to both solid sales growth and maintaining gross margins. It said its share of a Joint Venture in Saudi Arabia contributed £311,000 to pre-tax profit, up from £252,000.
