Serco Group plc has raised its full-year profit guidance by £10 million to £270 million, driven by strong performance in the first half, with underlying operating profits exceeding expectations at around £140 million and ongoing share buybacks. The company attributes this positive outlook to productivity enhancements, strategic acquisitions, and a promising pipeline for medium-term growth. Despite concerns about potential international election impacts, Serco remains optimistic about its future work prospects. Revenue for the first six months is in line with forecasts at £2.4 billion, with growth in international immigration services and defense partially offsetting declines in other areas.
