Treatt plc provided earnings guidance for the full year ended September 30, 2015. For the year, the company confirmed that the group has performed well in the second half of the financial year and expects to report revenue and profit before tax for the year ended 30 September 2015 in line with its expectations. Revenues in the year have been positively impacted by historically high market prices for certain key ingredients, particularly lemon and lime oil, although this has not resulted in higher gross margins.
