Weir, the FTSE 100 mining equipment maker, expects to deliver full-year revenue and operating profit in line with market expectations, backed by a growing orderbook.
Operating margins are expected to be above 20% for 2026, with strong cash conversion.
The focus for the fourth quarter is on delivering a large backlog of aftermarket orders, the spare parts and services that make up most of its business.
Weir flagged short-term risks from the conflict in the Middle East, international freight availability and the pace of recovery from mine disruptions in Chile.
Year-end net debt is expected to land slightly above its normal range of 0.5 to 1.5 times earnings before interest, tax, depreciation and amortisation (EBITDA), returning within it during 2027.
Net interest costs for the year are expected to be about £90 million.
Group orders rose 8% at constant currency in the three months to 30 September, to £687 million.
Stripping out acquisitions, orders were up 5%.
Aftermarket orders grew 10%, as miners pushed production of gold, copper and other critical metals from lower-grade ore.
Demand from oil sands customers was strong, helped by higher oil prices.
The Middle East conflict hit phosphate customers, who account for about 4% of revenue, as shortages of sulphur and ammonia forced them to cut output.
Extreme weather in Chile in July and August also disrupted activity.
Original equipment orders, for new machinery, rose 3%, with several larger projects in the Minerals division slipping into the fourth quarter.
ESCO, the division that makes digging teeth and buckets for excavators, saw original equipment orders fall 24% as large bucket and truck body orders were phased into the first half.
Its aftermarket orders jumped 14%.
Book-to-bill, the ratio of orders taken to sales shipped, was 1.10 for the year to date, meaning the orderbook is still growing.
Savings from Weir's Performance Excellence efficiency programme reached £80 million, against a 2026 target of £90 million.
Andrew Neilson, who became chief executive three months ago, said the orderbook "reflects a high level of underlying demand for our products".
