McBride jumped by a fifth as the own-label household products maker said people are still switching away from branded goods to cheaper options.
First-quarter volumes were 8% higher overall compared to the first quarter of last year, with private label growth of 10.8%.
"Consequently, for the first three months of the current financial year our business has traded £8m ahead of internal forecasts at an EBITA level," said the statement.
Inflation remains a problem, the group added, with labour, energy, and indirect cost inflation still rising, though raw material and packaging costs have stabilised.
Macroeconomic instabilities currently are another risk and might ultimately result in further input cost pressures.
