FAIR VALUE MEASUREMENTS
    We measure our financial assets and liabilities in accordance with Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures. ASC Topic 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The topic establishes market or observable inputs as the preferred sources of values, followed by assumptions based on hypothetical transactions in the absence of market inputs. The topic also establishes a hierarchy for grouping these assets and liabilities based upon the lowest level of input that is significant to the fair value measurement. The definition of each input is described below:
Level 1—Quoted prices in active markets for identical assets and liabilities.
Level 2—Quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar instruments in markets that are not active, and model‑derived valuations whose inputs are observable or whose significant value drivers are observable.
Level 3—Significant inputs to the valuation model that are unobservable.
    The classification of fair value measurement within the hierarchy is based upon the lowest level of input that is significant to the measurement.
Other financial instruments consist primarily of cash equivalents, accounts receivable, refundable income taxes, accounts payable, accrued liabilities, and, if any, advances under our credit facility. With the exception of investment securities, we believe cost approximates fair value for our financial instruments because of the short-term nature of these instruments.
Cash Equivalents—As of December 31, 2025, and December 31, 2024, we had cash equivalents of $5.9 million and $2.6 million, respectively.
Held-to-Maturity Investments—During the three months ended June 30, 2025, all of our held-to-maturity debt investments matured and as of December 31, 2025, we did not own any debt investment securities. As of December 31, 2024, we owned debt investment securities classified as held-to-maturity because we had the intent and ability to hold these investments to maturity. These held-to-maturity debt investment securities were carried at amortized cost, were recorded in "Short-term investments" on the Consolidated Balance Sheets, and consisted of the following (amounts in thousands):

Investments in Equity Securities—In May 2020, we acquired a non-controlling equity investment in W.D. Von Gonten Laboratories ("WDVGL") for $3.5 million. We initially accounted for this investment as an equity investment without a readily determinable fair value and elected to measure our investment, as permitted by GAAP, at cost plus or minus any adjustments for observable changes in prices resulting from orderly transactions for the identical or a similar investment of the same issuer or impairment.
In July 2022, WDVGL entered into an agreement (the “Purchase Agreement”) with National Energy Services Reunited Corporation (“NESR”), a British Virgin Islands corporation headquartered in Houston, Texas. Under the terms of the Purchase Agreement, WDVGL was combined with the consulting business owned by W.D. Von Gonten (“Consulting”) to form a new entity, W.D. Von Gonten Engineering, LLC (“Engineering”), and NESR purchased Engineering in a majority stock transaction at an agreed upon selling price. NESR stock received from the sale of Engineering was distributed to investors in WDVGL and Consulting in August 2024.
In February 2023, we received $0.2 million in cash for our investment in WDVGL. Initially, we recorded that cash received as a liability because we were required to return the cash to WDVGL if the sale of Engineering to NESR was not finalized. The sale of Engineering to NESR has since been finalized and the recorded value of our investment in WDVG was reduced to $3.3 million, which is the aggregate cost basis of the 336,773 shares of NESR stock we received in August 2024 related to the sale of WDVGL.
As required by Accounting Standards Codification ("ASC") Topic 321 - Investments-Equity Securities ("ASC 321"), equity securities were valued at fair value in the Consolidated Balance Sheet and unrealized gains and losses for investments in equity securities were included in "Other (expense) income" on the Consolidated Statement of Operations. At December 31, 2024, the fair value of our investment in NESR equity securities was $3.0 million and was included in "Long-term investments" on the Consolidated Balance Sheet at December 31, 2024, and the unrealized loss of $0.3 million was included in "Other (expense) income" on the Consolidated Statement of Operations for the year ended December 31, 2024.
In May 2025, we sold all shares of NESR we owned and received proceeds of $2.1 million. When the NESR shares were sold, the fair value of the shares was $2.5 million, and we recorded a realized loss of $0.4 million during the three months ended June 30, 2025. For the year ended December 31, 2025, the total loss (unrealized losses plus realized losses) related to this investment was $0.9 million, which is included in "Other (expense) income" on the Consolidated Statement of Operations.
Equity Method Investments—We are a limited partner with a 16% interest in PEP Ovation, LP ("Ovation") as of December 31, 2025, and 2024. This investment is accounted for under the equity method whereby we recognize our proportional share of the income or loss from our investment in Ovation on a one-quarter lag and is included in "Long-term investments" on the Consolidated Balance Sheets. For the years ended December 31, 2025, and 2024, our proportional share of Ovation's net loss was $0.4 million and $0.3 million, respectively.

About Fair Value Disclosures

Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.

Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
