HAMBURG (Reuters) - Europe's largest sugar producer Suedzucker on Thursday confirmed a 63% fall in quarterly operating profits and a cut in full-year earnings forecasts because of weak sugar markets. Suedzucker reported operating profit in the second quarter to Aug. 31 of its 2024/25 fiscal year of 114 million euros ($124.70 million), down from 310 million euros in the same quarter last year. Suedzucker had warned in September that its second quarter earnings would decline because of unexpectedly sharp deterioration in market expectations for its core sugar sector.
