Publisher and education business Pearson said that first-half profits would likely be lower than last year as it starts to phase in 150m pounds of restructuring costs.
Nevertheless, the company, which labels itself as the "world's leading learning company", reiterated its forecast for full-year operating profits to be flat on 2012.
Pearson said that trading in the first quarter was in line with its expectations with sales up 3.0% at constant currency at £1.2bn.

The firm said that it expects the external environment to stay "challenging" for its developed world and publishing businesses in 2013 due to a number of cyclical and structural factors: "pressures on education budgets and college enrolments; retail consolidation; the shift in our business model from print sales to digital subscriptions; changing consumer behaviour and a dynamic competitive landscape."
Nevertheless, it said that there is a "considerable growth opportunity" in education, driven by a growing global middle class, adoption of learning technologies, the connection between education and career prospects and increasing consumer spend, especially in emerging economies.
As announced as part of its full-year results in February, Pearson is to recognise £150m in restructuring costs this year in order to "reshape the company to take advantage of these significant growth opportunities".
This investment is an attempt to accelerate the transition from print to digital and from developed to developing economies.
The company also intends to separate Penguin activities from Pearson's core operation in preparation for the subsidiary's merger with Bertelsmann's Random House book publisher, announced in October 2012.
The stock was up 0.61% at 1,156p by 08:23 on Friday morning.
