The year-over-year change is due to the exceptional North American OSB prices in the Q1 of last year – the highest in 10 years.

North American operations generated EBITDA of US$17m in the quarter versus US$21m in the prior quarter and US$106m in the same quarter last year. European operations generated EBITDA of US$13m million in the quarter versus US$12m in the prior quarter and US$10m in the same quarter last year.

"Severe weather conditions across North America presented both market and operational challenges that impacted our business in the first two months of the year," said Peter Wijnbergen, president and ceo.
