Like-for-like sales were stable over the nine-month period to September 30, 2023 despite a contraction of 3.1% in the third quarter of the year versus third-quarter 2022 given the more difficult pricing comparison basis due to the price increases implemented proactively in the last few years. In a less inflationary environment prices rose by 5.9% over the nine-month period and by 1.9% in the third quarter, reflecting overall sequential price stability since the start of the year, generating a positive price-cost spread once again.
