Weir PLC (WEIR), the global mining technology group, reported an 8% increase in group orders on a constant currency basis for the third quarter ended 30 September 2026, driven by robust aftermarket demand across its Minerals and ESCO divisions. The company confirmed it remains on track to deliver full-year results in line with current market expectations, including operating margins above 20%. New Chief Executive Andrew Neilson, in post for three months, cited strong underlying momentum in core mining markets despite geopolitical and weather-related headwinds. Investors will be watching fourth-quarter execution closely, given a large aftermarket backlog and several deferred original equipment orders.

Minerals and ESCO Aftermarket Drive Weir's Q3 Order Growth

Aftermarket orders were the primary engine of Weir's third-quarter performance. Minerals aftermarket orders rose 7%, adding £23m year-on-year, supported by healthy demand despite short-term headwinds, with organic growth of 5%. ESCO aftermarket orders grew 14%, adding £26m, led by strong growth in mining ground-engaging tools and Software Solutions, with organic growth of 10%. Total group aftermarket orders reached £558m in the quarter, compared with £496m in Q3 2025. Weir attributed the increase to customers driving production of critical minerals at lower ore grades, particularly in gold, copper and oil sands markets, where activity levels were described as notably positive in the announcement.

ESCO OE Orders Decline on Phasing; Minerals Pipeline Defers Larger Projects to Q4

Original equipment performance was mixed across divisions. Minerals OE orders rose 6%, adding £7m, as customers continued brownfield expansion and debottlenecking activity. However, the announcement states that several larger project opportunities were delayed into Q4 due to phasing. ESCO OE orders declined 24%, a reduction of £3m, reflecting the annual phasing of large bucket and truck body orders following a strong first half. Total group OE orders for Q3 2026 were £129m against £122m in Q3 2025. Weir noted that ESCO OE orders have increased year-to-date overall, with the quarterly decline representing timing rather than a deterioration in underlying demand.

Performance Excellence Savings Reach £80m as Production Transfers Near Completion

Weir reported that production transfers within its Minerals division are nearing completion, delivering cumulative Performance Excellence programme savings of £80m. The company remains on track to achieve its full-year 2026 target of £90m in cumulative savings. Net debt is expected to land slightly above its normal operating range of 0.5 to 1.5 times net debt to EBITDA at year end 2026, with a return to within that range expected over the course of 2027. Net interest expense is guided at approximately £90m for the full year. Weir also cited progress on its S4Hana implementation as a future enabler of operational efficiency.

Middle East Conflict and Chilean Weather Events Present Ongoing Sectoral Risks for Weir

The announcement identifies several specific risk factors Weir is actively monitoring. Conflict in the Middle East has adversely affected phosphate customers, which account for approximately 4% of group revenue, as availability of raw material inputs including sulphur and ammonia has been disrupted. Dredging activity has also reduced, with approximately 90% of large barges reported as now in port. Extreme weather events in Chile disrupted customer activity in July and August, though Chilean customers are described as focused on maximising production in Q4 to offset the shortfall. Weir also flagged international freight availability as a broader sectoral headwind heading into the final quarter.
