Fiscal 2022 fourth quarter consolidated revenue grew 18% year over year, driven by increased Salt segment sales volumes and favorable Plant Nutrition average selling price.

2 The company’s fiscal 2022 results in this earnings release reflect the change in the fiscal year-end from Dec. 31 to Sept. 30. The fiscal 2022 results are reported for the twelve-month period from Oct. 1, 2021 to Sept. 30, 2022, and the company has presented comparable results for the Oct. 1, 2020 to Sept. 30, 2021 period.

3 All amounts in this press release represent results from continuing operations, except for amounts pertaining to the condensed consolidated statements of cash flows which include results from discontinued operations, unless otherwise noted.

Plant Nutrition SOP average selling price increased 48%, partially offset by reduced sales volumes year over year. Consolidated operating earnings of $7.5 million, up $5.4 million year over year, and adjusted EBITDA of $35.0 million up $2.0 million year over year, were also driven by strong Salt segment sales volume and the favorable impact of Plant Nutrition higher average selling price partially offset by increased production and distribution costs.

Fiscal 2022 consolidated revenue grew 9% year over year, driven primarily by higher Salt segment sales volumes. Plant Nutrition SOP average selling price increased 33%, partially offset by a 29% decline in sales volumes year over year. Consolidated operating earnings of $44.4 million, down $62.7 million year over year, and adjusted EBITDA of $187.1 million, down $53.7 million year over year, were impacted by increased production and distribution costs partially offset by the favorable impact of increased pricing in the Plant Nutrition segment.

Salt segment fiscal 2022 fourth-quarter revenue totaled $188.9 million, up 18% year over year, driven by a 15% increase in sales volumes and a 3% increase in average selling price. Fourth-quarter sales volume increased for both the highway deicing and consumer and industrial salt businesses from the prior year. Highway deicing average selling price increased 7% year over year. Consumer and industrial average selling price increased 5% from prior year due to continued price increases across most product categories. Operating earnings decreased 27% to $16.3 million, while EBITDA declined 17% to $33.1 million from the prior-year period, both impacted by continued inflationary pressures and increased production and distribution costs.

For the full fiscal year, Salt segment revenue grew 12% to $1.0 billion from $899.6 million in the comparable 2021 period, primarily driven by a 11% increase in sales volumes. Highway deicing sales volumes rose 12% on higher bid season commitments and consumer and industrial sales volumes grew 6%. Salt segment average selling price was up 1% year over year. Salt segment generated $117.4 million in operating earnings and EBITDA of $181.9 million, down 34% and 27% respectively, from comparable 2021 period results. Fiscal 2022 operating margins of 12% and EBITDA margins of 18% were down 820 and 960 basis points respectively, versus the comparable prior-period results, also driven primarily by continued inflationary pressures and increased production and distribution costs.

Plant Nutrition segment fourth-quarter revenue totaled $57.8 million, up 17% year over year, driven by a 48% increase in average selling price partially offset by a 22% decrease in sales volumes. Operating earnings totaled $12.6 million for the quarter, up $12.8 million from an operating loss of $0.2 million in the prior-year period, and EBITDA increased $13.1 million to $21.8 million, as higher average selling price more than offset reduced sales volumes, which were impacted by inventory constraints and higher per-unit costs due to reduced production volumes.

For the full fiscal year, the segment generated $222.3 million in revenue, 5% below the comparable prior-period results, primarily due to a 29% decrease in sales volumes, largely offset by a 33% increase in average selling price. Operating earnings for the full fiscal year totaled $37.1 million and EBITDA totaled $72.7 million, up $28.0 million and $27.8 million respectively from the comparable prior-year period, both impacted by higher average selling price reflecting strong global fertilizer supply-demand conditions partially offset by reduced sales volumes due to inventory constraints and higher per-unit product and logistics costs related to lower production volumes.

Net cash provided by operating activities amounted to $120.5 million for fiscal 2022, down $28.9 million year over year, driven by reduced earnings.

Net cash used in investing activities was $80.0 million for fiscal 2022 compared to net cash provided by investing activities of $253.2 million in the comparable prior-year period, largely reflecting a substantial decrease in year-over-year asset sale proceeds and the fiscal 2022 $45 million investment in Fortress. Capital spending for fiscal 2022 was essentially flat year over year, totaling $96.7 million versus $93.8 million in the comparable year-ago period.

Net cash used for financing activities was $14.3 million for fiscal 2022 compared to $417.5 million in the comparable prior-year period, primarily reflecting lower net asset sale proceeds which were applied to debt reduction during the prior year, partially offset by a year-over-year reduction in dividends paid in fiscal 2022.

The company ended the fiscal year with $181.0 million of liquidity, comprised of $46.1 million in cash and cash equivalents and $134.9 million of availability under its $300 million revolving credit facility. Subsequent to fiscal year-end, the company closed the previously announced equity transaction with KM&T and received $252 million in cash, before fees.

For fiscal 2023, the company has modified its approach to providing annual earnings guidance. While demand for deicing salt is stable over time, the nature of winter weather and the manner in which customers respond to weather events make forecasting deicing sales volumes difficult during any single year. Below the company provides a range of estimated potential earnings outcomes that consider various winter weather scenarios.

(1) Mild and Strong Winter scenarios reflect management estimates of the potential impact to the presented line items assuming mild or strong winter weather. The company utilizes an array of information, including historical weather data and sales-to-commitment outcomes, to develop measures that are then applied to its 2023 Range to estimate these amounts.

(2) Range for fiscal 2023 reflects the company's estimated book of business for the period and assumes normalized weather conditions and average historical sales-to-commitment outcomes.

The company’s focus for the Salt segment in 2023 is on improving profitability to historical levels by adjusting its pricing strategy and recalibrating its sales mix to areas where it has natural competitive advantages that result in higher profit margins. The company's North American highway deicing bidding process for the 2022-2023 winter season has been completed and the company expects its average contract price for the upcoming winter season to be approximately 15% above the prior year's bid season results. The company estimates that its total committed bid volumes will decrease by approximately 9% compared to prior-year bid season results as it prioritizes value over volume. Consistent with prior years, Compass Minerals expects that approximately 75% of its highway deicing sales will be achieved in the first half of the fiscal year.

Within the Plant Nutrition segment, the company expects the average sales price for the fiscal year to be moderately higher year over year despite moderating sequentially throughout the year. Sales volumes in fiscal 2023 are expected to be comparable to the prior year. The company expects higher production costs due to adverse weather conditions during the most recent evaporation season, resulting in higher per-unit processing costs at its Ogden, Utah facility. The segment is also expected to incur incremental costs related to operational strategies to mitigate the effects of ongoing drought conditions in Utah.

* Corporate and other expense includes operating expenses of $10 to 12 million related to lithium development and non-cash losses of approximately $5 million related to the equity investment in Fortress; it excludes depreciation, amortization and stock-based compensation.

As the company continues to invest in developing its lithium resource, related operating expenses in the range of $10 to $12 million are projected for fiscal 2023, versus approximately $8 million in fiscal 2022.

Total capital expenditures for fiscal 2023 are projected to be in the range of $175 million and $230 million, comprised of lithium development capital spending in the range of $75 million to $120 million (funded by proceeds from recent KM&T transaction) and sustaining capital spending in the range of $100 million to $110 million.
