In an update to the stock market, the business, which has a registered office in Dundee but has its headquarters in London, said sales for the six months to November 30 were likely to be 5% ahead on a like-for-like and constant currency basis.
Adding in a £3 million contribution from Slovakian civil engineering supplier Texiplast, which Low & Bonar paid £16m for in September, sales were 6% up.
The company, which has interests in sectors ranging from agriculture to construction and transport, said: "The much improved second-half performance has resulted in full-year constant currency sales growth of circa 3%."
It added that annual pre-tax profits were on course to meet market expectations.
It its previous financial year, Low & Bonar's yarns division, which employs around 120 people in Dundee, contributed to pre-tax profits dropping from £23.4m to £6.1m.
The carpet-backing and artificial grass-making yarns arm posted an operating loss of £1.8m in the 12 months to November 30, 2012.
The company also took an £11.2m impairment charge on the division.
Total revenue in that year was £380.5m.
The yarns business had returned to profit in the six months to May 31 this year. However, interim profits were down from £6.3m to £4m with that result blamed on poor weather conditions in several markets.
Shares closed yesterday down 1.75p, or 2.3%, at 74.5p.
