Compass Minerals reported lower fourth-quarter revenue and operating earnings compared to the prior year, driven primarily by weaker winter weather, the continued devaluation of the Brazilian real, higher costs in the company's Plant Nutrition North America segment and revenue and expense impacts associated with the COVID-19 pandemic. However, the company improved year-over-year operating and EBITDA margins in its Salt segment, and the Goderich mine achieved its highest monthly production level during the fourth quarter since its full conversion to continuous mining and haulage.
The company estimates the combination of weaker winter weather, devaluation of the Brazilian real and COVID-19 impacts had a negative effect on full-year 2020 operating income of approximately $67 million.
Full-year 2020 capital spending was $84.9 million, below the low end of the previously announced guidance range.
Goderich mine production demonstrated continued efficiency gains with a 23% increase in December and 17% increase for the full year, both versus 2019 respectively.
The company has initiated a strategic separation of its South American assets into two businesses, chemicals and specialty plant nutrition, with the intention of enabling a targeted and efficient sales process to unlock maximum value for each set of assets; both processes are currently underway.
Strong production performance at the Goderich and Cote Blanche mines and normalized winter weather activity, combined with improving agriculture fundamentals in North and South America, are expected to produce a substantial increase in full-year 2021 Adjusted EBITDA from 2020 results to the range of $330 million to $360 million.
