Balfour Beatty stock (ISIN GB0002422382) is set to return to the FTSE 100 on October 1, 2026, after a 17-year absence from London's blue-chip index. The move follows first-half underlying operating profit of GBP 119.0 million, up from GBP 77.0 million a year earlier, according to Financial News on September 18, 2026.
FTSE 100 return begins October 1
Balfour Beatty will be promoted from the FTSE 250 to the FTSE 100 on October 1, 2026, according to Construction News on September 29, 2026. The company last held a place in the index in 2009.
The index change gives the stock a larger benchmark profile just as its infrastructure pipeline expands. The same report put the order book at GBP 22.9 billion as of late June and cited a GBP 325.0 million Scottish power-transmission project alongside a GBP 315.0 million road-maintenance contract.
Profit growth strengthens the case
Revenue reached GBP 5.56 billion in the six months to June 26, 2026, while underlying earnings per share rose from GBp 14.40 to GBp 21.70. The US construction division swung from a GBP 11.0 million loss to a GBP 22.0 million profit, providing the clearest operational comparison in the interim figures.
Management also lifted its full-year profit-growth outlook from high single-digit growth to low double-digit growth. Statutory net cash stood at GBP 1.012 billion at the half-year, compared with GBP 837.0 million at the end of 2025, while the company had completed GBP 102.0 million of a GBP 200.0 million buyback.
Stock remains below its yearly high
Balfour Beatty had a market capitalization of GBP 4.3 billion on September 30, 2026. Its 52-week range was GBp 636.50 to GBp 973.00, leaving the quoted level below the yearly high while the FTSE 100 promotion adds a new benchmark event.
