Castings plc (CGS), the West Midlands-based iron casting and machining group focused on the European heavy truck market, has issued a trading update for the year ended 31 March 2027, warning that adjusted profit before tax will fall short of previous analyst expectations. The Board now anticipates FY27 adjusted profit before tax at a level broadly consistent with the prior year, excluding historical R&D tax credits, down from the analyst consensus of £12.9 million. The downgrade follows a third-party power supply failure at its William Lee site that disrupted first-half production, with catch-up costs persisting even after power was restored at the end of May. Revenue expectations, however, remain in line with the market consensus of £181.1 million.

Key Points

  • Castings plc (CGS) — leading UK iron casting and machining group based in Brownhills, West Midlands
  • Board reduces FY27 adjusted profit before tax expectations to broadly prior-year levels, citing unresolved production arrears from the William Lee power outage
  • Pre-announcement analyst consensus stood at revenue of £181.1m and adjusted profit before tax of £12.9m for FY27; revenue guidance is maintained, profit guidance is cut
  • Investors should watch the half-year results, scheduled for 11 November 2026, for further detail on the William Lee recovery and productivity progress

William Lee Power Failure Drives FY27 Profit Warning at Castings plc

The central issue flagged in the 26 October 2026 announcement is a third-party power supply failure at Castings' William Lee site. Power was restored at the end of May, but the company states that the incremental cost of catching up production continued beyond that date, compounding the first-half impact. Management at William Lee are now focused on optimising a new foundry line rather than managing the immediate disruption. The episode represents a company-specific operational risk that the announcement confirms has not yet been fully resolved in terms of production arrears, even as the underlying power problem has been addressed.

Revenue Held But Adjusted Profit Before Tax Guided Lower Than the £12.9m Analyst Consensus

Castings' Board states that revenue expectations remain in line with the analyst consensus of £181.1 million for FY27, suggesting underlying commercial demand has held up across the group. However, because production arrears from the first-half disruption have not yet been cleared, the Board is reducing adjusted profit before tax expectations to a level broadly consistent with the prior year, excluding historical R&D tax credits. The prior-year profit figure used as the new benchmark was not separately restated in the announcement, meaning investors will need to refer to previously published accounts to quantify the precise revised expectation.

Strong Order Book Supports Castings' European Heavy Truck and Diversified Sector Exposure

Despite the profit warning, the announcement states that the order book remains strong across the group. Castings holds long-term relationships with major OEMs in the European heavy truck market, where platform lifecycles typically exceed ten years. Beyond commercial vehicles, the group also supplies the wind power, agriculture, rail, and material handling sectors. With gross foundry capacity of 80,000 tonnes per annum and investment in automation for high-mix, low-volume just-in-time production, the company's competitive positioning appears intact, though delivery against the strong forward order book in the second half will be critical to recovering lost ground.

Half-Year Results Scheduled for 11 November 2026 as Management Targets Cost Control

Castings has confirmed it intends to publish its half-year results on 11 November 2026, which will provide investors with a more granular view of the financial damage from the William Lee disruption and progress on clearing production arrears. The company's stated priorities are productivity improvement and cost control to meet second-half commitments. Investors may be watching closely to assess whether the new foundry line optimisation at William Lee, combined with a reportedly robust order book, is sufficient to support a recovery in profitability through the remainder of FY27.
