Top-line growth achieved in all segments.

Second-Quarter Highlights:

• Total company revenue up 8 percent year-over-year

• Salt segment operating earnings up 17 percent versus prior year

• Year-over-year sales volume and revenue growth in both Plant Nutrition segments

• New labor agreement reached with Goderich mine employees

OVERLAND PARK, Kan. (August 6, 2018) – Compass Minerals (NYSE: CMP) reported a second-quarter net loss of $7.6 million, or $0.23 per diluted share, compared to a net loss of $6.4 million, or $0.19 per diluted share, in the prior-year period. Operating earnings in the second quarter declined 53 percent from 2017 results due to increased depreciation expense. Adjusted EBITDA increased 13 percent from second-quarter 2017 results.

“Our second quarter is typically our lowest earnings period, however I am pleased that we delivered top-line growth across all our businesses. This provides a strong indicator that the fundamental market conditions for our businesses globally have continued to improve in 2018,” said Fran Malecha, Compass Minerals’ president and CEO. “I believe we are now better positioned to deliver on our efficiency investments in our salt business, drive growth in our specialty plant nutrition business and capitalize on strong grower economics in South America.”

SALT BUSINESS SUMMARY

Second-quarter salt segment revenue increased 11 percent from $109.0 million in the 2017 second quarter to $121.1 million in the second quarter of 2018, as a 17 percent increase in sales volumes was partially offset by a 5 percent decline in average selling prices. Salt segment sales volumes benefited from a 27 percent increase in highway deicing demand driven primarily by a combination of increased demand in North America from April snow events and robust early summer restocking orders in the U.K. The decline in average selling prices was driven by a shift in sales mix in favor of highway deicing products, which have a lower average selling price compared to consumer and industrial products.

Salt segment operating earnings increased $1.8 million, or 17 percent, to $12.5 million from second-quarter 2017 results of $10.7 million. Operating earnings margin for the segment expanded to 10.3 percent from 9.8 percent in the year-ago quarter primarily as a result of improved operating rates in the U.K. and a more profitable sales mix. Salt segment EBITDA increased 14 percent to $26.6 million compared to $23.4 million in the second quarter of 2017.

Goderich Mine Update

On July 16, 2018, unionized employees at the company's Goderich, Ontario, mine ratified a new three-year collective bargaining agreement ending an 11-week strike. The new agreement further aligns our operations with our investments in continuous mining and provides the flexibility to operate the mine more efficiently.

Bid Season Update

Approximately 75 percent of the annual North American highway deicing bidding process has been completed. While market-wide average bid volumes have increased this season compared to the 2017-2018 season, the company currently does not expect to increase salt sales volume expectations for 2018 due to production constraints. These constraints are due to the impact of the ongoing ramping up of production following the 11-week strike at the Goderich mine, which included an unexpected 7-day full work stoppage near the end of the strike. The company’s bid season results to date indicate that Compass Minerals’ expected average contract price will increase approximately 15 percent versus prior-season’s results.

PLANT NUTRITION BUSINESS SUMMARY

Steady demand in North America for sulfate of potash (SOP) and micronutrients combined with a surge in pre-season demand for specialty nutrients in Brazil driven by attractive crop economics resulted in year-over-year increases in second-quarter 2018 sales volume and revenue for Compass Minerals' Plant Nutrition business.

Modest improvements in sales volumes and average selling prices resulted in a 3 percent increase in Plant Nutrition North America segment revenue to $51.8 million from $50.5 million in the second quarter of 2017.

Operating earnings for the Plant Nutrition North America segment dropped $3.4 million from second-quarter 2017 results to $4.2 million. While the company reported a significant decline in segment logistics costs, increased production costs resulting from a year-over-year step-up in depreciation expense pressured earnings and compressed operating margins. The increased depreciation expense was driven by the commissioning of new production assets at the company's Ogden, Utah, SOP plant. The segment's EBITDA rose 6 percent to $17.2 million in the second quarter of 2018 from $16.2 million in the prior-year period.

Plant Nutrition South America segment revenue rose 8 percent to $71.1 million from second-quarter 2017 results of $66.1 million as sales volumes increased 5 percent and average selling prices improved 2 percent. Strong pre-season demand for specialty nutrients pushed agriculture sales volumes up 14 percent year-over-year, while chemical solutions sales volumes declined 4 percent. Average selling prices for agriculture products improved 4 percent from 2017 second-quarter results primarily due to sales mix and increased raw material cost passed through to customers. Chemical solutions average price declined 5 percent. While both businesses experienced disruptions in May due to the national truckers' strike in Brazil, the company expects growth in agriculture sales through the rest of the year to offset much of the impact from all lost sales in the second quarter. Year-over-year changes in the weighted average exchange rate of the Brazilian reais to the U.S. dollar negatively impacted our second-quarter 2018 Plant Nutrition South America revenue and average selling price results by 11 percent.

Plant Nutrition South America operating earnings for the 2018 second quarter were $0.7 million compared to $0.8 million in 2017, a decline of 13 percent primarily driven by foreign currency translation. EBITDA for the segment increased to $6.7 million from $6.4 million in the 2017 second quarter.

OTHER FINANCIAL HIGHLIGHTS

Cash flow from operations increased 25 percent to $181.6 million from second-quarter 2017 results, primarily due to a year-over-year improvement in working capital.

Interest expense increased $2.6 million from prior-year expense of $12.3 million as a result of higher interest rates on the floating-rate debt held by the company in the U.S.

The company now expects a full-year 2018 tax rate of 21 percent, down from prior estimate of 25 percent, due to discrete tax benefits and shifts in our pre-tax earnings by jurisdiction.

OUTLOOK

Strong fundamentals in the highway deicing markets in North America and the U.K. are expected to result in improved pricing and increased sales volumes for the remainder of 2018 compared to prior-year results, assuming average winter weather. Some of the benefits of increased pricing, however, are expected to be offset by increased logistics costs and Goderich post-strike transition impacts.

Plant Nutrition North America revenue in the second half of the year is expected to benefit from steady demand in the fall fertilizer season across all product lines. As a result, our full-year Plant Nutrition North America sales volume guidance has increased modestly. We also expect year-over-year revenue growth to continue for the second half of 2018 at operating margins similar to prior-year results.

Improving grower economics in Brazil due to crop prices and the strong U.S. dollar are expected to drive robust demand for our Plant Nutrition South America products. Given these factors, we expect year-over-year growth in revenue for the second half of 2018 with similar operating

margins to second-half 2017 results, although further weakening of the Brazilian reais may mute some of the growth when translated into U.S. dollars.

Non-GAAP Measures

Management uses a variety of measures to evaluate the company’s and its operating segments’ performance. While the consolidated financial statements provide an understanding of the company’s overall results of operations, financial condition and cash flows, management analyzes components of the consolidated financial statements to identify certain trends and evaluate specific performance areas. In addition to using U.S. generally accepted accounting principles (“GAAP”) financial measures, management uses EBITDA and EBITDA adjusted for items which management believes are not indicative of the company’s ongoing operating performance (“Adjusted EBITDA”) to evaluate the operating performance of the company’s core business operations because its resource allocation, financing methods, cost of capital and income tax positions are managed at a corporate level, apart from the activities of the operating segments, and the operating facilities are located in different taxing jurisdictions, which can cause considerable variation in net earnings. The company also uses EBITDA and Adjusted EBITDA to assess its consolidated and segment operating performance and return on capital against other companies and to evaluate potential acquisitions or other capital projects. These measures are not calculated under GAAP and should not be considered in isolation or as a substitute for net earnings, operating earnings, cash flows or other financial data prepared in accordance with GAAP or as a measure of overall profitability or liquidity. EBITDA and Adjusted EBITDA exclude interest expense, income taxes and depreciation and amortization, each of which are an essential element of the company’s cost structure and cannot be eliminated. Consequently, any measure that excludes these elements has material limitations. While EBITDA and Adjusted EBITDA are frequently used as measures of operating performance, these terms are not necessarily comparable to similarly titled measures of other companies due to the potential

inconsistencies in the method of calculation. The calculation of EBITDA and Adjusted EBITDA as used by management is set forth in the following tables.
