Tate & Lyle has warned its full-year pre-tax profit is likely to be “modestly below” market expectations due to a lower than expected contribution from its Sucralose sweetener.

“It is likely that sales and profits of Splenda Sucralose for the year to 31 March 2007 will only modestly exceed the prior year due to a slower than anticipated acceleration of uptake from major customers,” the sugar manufacturer said in a trading update.

“Group profit before tax, exceptional items and amortisation for the year to 31 March 2007 is now likely to be modestly below current market expectations, albeit well ahead of the previous year,” it added.
