Fair Value Disclosures [Abstract]
Fair Value Measurements	17. Fair Value Measurements Fair value is defined under GAAP as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. The following fair value hierarchy prioritizes the inputs in valuation methodologies used to measure fair value: Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 – Unobservable inputs for the asset or liability. These fair value measurements require significant judgment. The valuation methodologies used for our assets and liabilities measured at fair value and their classification in the valuation hierarchy are described below. The carrying value of our cash, cash equivalents, and restricted cash approximates fair value because of their short-term nature and is classified as Level 1. Covista maintains a rabbi trust with investments in stock and bond mutual funds to fund obligations under our nonqualified deferred compensation plan. The fair value of the investments in the rabbi trust included in prepaid expenses and other current assets on the Consolidated Balance Sheets as of June 30, 2026 and 2025 was $15.6 million and $12.8 million, respectively. These investments are recorded at fair value based upon quoted market prices using Level 1 inputs. The carrying value of the credit extension programs, which approximates their fair value, is included in accounts and financing receivables, net and other assets, net on the Consolidated Balance Sheets as of June 30, 2026 and 2025 of $24.2 million and $27.1 million, respectively, and is classified as Level 2. See Note 9 “Accounts and Financing Receivables” for additional information on these credit extension programs. Covista has a nonqualified deferred compensation plan for highly compensated employees and its Board members. The participant’s “investments” are in a hypothetical portfolio of investments which are tracked by an administrator. Changes in the fair value of the nonqualified deferred compensation obligation are derived using quoted prices in active markets based on the market price per unit multiplied by the number of units. Total liabilities under the plan included in accrued liabilities on the Consolidated Balance Sheets as of June 30, 2026 and 2025 were $15.7 million and $13.5 million, respectively. The fair value of the nonqualified deferred compensation obligation is classified as Level 2 because its inputs are derived principally from observable market data by correlation to the hypothetical portfolio of investments. As of June 30, 2026 and 2025, the principal amount of our Term Loan B was $510.0 million and $153.3 million, respectively, with a fair value as of those dates of $512.9 million and $153.8 million, respectively. The valuation of the Term Loan B was based upon quoted market prices in a non-active market and is classified as Level 2. As of June 30, 2025, the principal amount of our Notes was $405.0 million, with a fair value of $402.8 million. The valuation of the Notes was based upon quoted market prices and is classified as Level 1. See Note 13 “Debt” for additional information on our Term Loan B and Notes. We recorded asset impairments of $6.4 million on operating lease assets and property and equipment for the year ended June 30, 2025 as a result of adjusting the respective carrying values to fair values. The fair values were estimated using Level 3 inputs. These impairments were recorded within student services and administrative expense in the Consolidated Statements of Income. During the second quarter of fiscal year 2026, we made a $5.0 million investment in a business. We do not have the ability to exercise significant influence over the investee and therefore have recorded the investment as an equity investment without readily determinable fair value within other assets, net on the Consolidated Balance Sheets. We will adjust the carrying value of this equity investment for observable price changes and impairments with changes in the measurement recognized through net income. Covista has elected not to measure any assets or liabilities at fair value other than those required to be measured at fair value on a recurring basis. Assets measured at fair value on a nonrecurring basis include goodwill, intangible assets, and assets of businesses where the long-term value of the operations are deemed to be impaired. Goodwill and indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually or more frequently if circumstances arise indicating potential impairment. This impairment review was most recently completed as of May 31, 2026. See Note 12 “Goodwill and Intangible Assets” for additional information on the impairment review, including valuation techniques and assumptions.

17. Fair Value Measurements

Fair value is defined under GAAP as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. The following fair value hierarchy prioritizes the inputs in valuation methodologies used to measure fair value:

Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3 – Unobservable inputs for the asset or liability. These fair value measurements require significant judgment.

The valuation methodologies used for our assets and liabilities measured at fair value and their classification in the valuation hierarchy are described below.

The carrying value of our cash, cash equivalents, and restricted cash approximates fair value because of their short-term nature and is classified as Level 1.

Covista maintains a rabbi trust with investments in stock and bond mutual funds to fund obligations under our nonqualified deferred compensation plan. The fair value of the investments in the rabbi trust included in prepaid expenses and other current assets on the Consolidated Balance Sheets as of June 30, 2026 and 2025 was $15.6 million and $12.8 million, respectively. These investments are recorded at fair value based upon quoted market prices using Level 1 inputs.

The carrying value of the credit extension programs, which approximates their fair value, is included in accounts and financing receivables, net and other assets, net on the Consolidated Balance Sheets as of June 30, 2026 and 2025 of $24.2 million and $27.1 million, respectively, and is classified as Level 2. See Note 9 “Accounts and Financing Receivables” for additional information on these credit extension programs.

The participant’s “investments” are in a hypothetical portfolio of investments which are tracked by an administrator. Changes in the fair value of the nonqualified deferred compensation obligation are derived using quoted prices in active markets based on the market price per unit multiplied by the number of units.

The fair value of the nonqualified deferred compensation obligation is classified as Level 2 because its inputs are derived principally from observable market data by correlation to the hypothetical portfolio of investments.

As of June 30, 2026 and 2025, the principal amount of our Term Loan B was $510.0 million and $153.3 million, respectively, with a fair value as of those dates of $512.9 million and $153.8 million, respectively. The valuation of the Term Loan B was based upon quoted market prices in a non-active market and is classified as Level 2. As of June 30,

2025, the principal amount of our Notes was $405.0 million, with a fair value of $402.8 million. The valuation of the Notes was based upon quoted market prices and is classified as Level 1. See Note 13 “Debt” for additional information on our Term Loan B and Notes.
