[1] In connection with the sale of the CCS segment that was completed on January 9, 2026, the terms of the Purchase Agreement with Amphenol required that the CCS segment be transferred on a debt‑free basis, and therefore, the Company repaid its third‑party borrowings at closing using a portion of the proceeds from the sale of the CCS segment. Accordingly, all third-party debt obligations remained classified as long-term debt on the Condensed Consolidated Balance Sheets as of December 31, 2025. However, in accordance with accounting guidance, interest expense on debt that is required to be repaid as a direct result of a disposal transaction that qualifies as a discontinued operation is reported within discontinued operations. Because the closing of the divestiture required repayment of all outstanding third‑party debt due to the contractual requirement to deliver the business debt‑free, all interest expense has been presented within discontinued operations for all periods presented.

Because the closing of the divestiture required repayment of all outstanding third‑party debt due to the contractual requirement to deliver the business debt‑free, all interest expense, including the write-off of $101.3 million of unamortized debt issuance costs and original issuance discount associated with the debt redemption, has been presented within discontinued operations for all periods presented.
[3] Other income (expense), net includes a loss of $11.3 million on the extinguishment of debt, for the six months ended June 30, 2026, associated with the divestiture of the CCS segment.
