Compass Minerals Reports Fourth-Quarter Snow-Event Data

Late start to winter pressured sales volumes.

OVERLAND PARK, Kan.–(BUSINESS WIRE)–Compass Minerals (NYSE: CMP) reported above-average winter weather in
its primary North American service areas, while the company’s highway
deicing sales volumes were slightly below the 10-year average.

Eleven representative cities in the company’s primary North American
highway deicing service area reported 57 snow events during the fourth
quarter of 2017, compared to 50 in the fourth quarter of 2016 and the
10-year average of 45.2 events.

The company sold approximately 3 million tons of highway deicing salt
products in the period, which was essentially unchanged from 2016
fourth-quarter results. This total includes all highway maintenance
products sold in the U.S., Canada and the U.K., as well as rock salt
sold to the chemical industry. Sales of all salt products totaled 3.6
million tons in the 2017 period compared to 3.7 million tons in the
fourth quarter of 2016.

“We are pleased to see improved snow event activity so far this winter,
although much of the increase occurred in cities in the eastern portion
of our market, which is typically a lower sales volume area for us,”
said Fran Malecha, Compass Minerals’ president and CEO. “The
continuation of strong winter weather in early 2018, however, bodes well
for the underlying market fundamentals of the North American salt
business in 2018 and beyond.”

Although total snow event activity was above average, much of the
activity occurred in the last half of December, with 15 snow events
occurring in the last week of the month. This is expected to shift some
sales into the first quarter of 2018 as customers replenish inventories.

Snow Events Note: The number of snow
events reported may not directly correlate to Compass Minerals’ deicing
results due to a variety of factors, including the relative significance
to the company of the cities represented and differences in the amount
of salt purchased by customers to establish their pre-season stockpiles.
The weather data should be used only as an indicator of the year-to-year
variations in winter weather conditions in these cities. Compass
Minerals draws its weather data from the U.S. National Weather Service
and National Climatic Data Center and Environment Canada without
weighting or other adjustments.
