The BHI Loan Agreement includes other customary affirmative and negative covenants, including payment and covenant events of default. *HSBC Bank 2024* Loan** Concurrently with the purchase transaction with EGPNA, on January 2, 2024, the Company entered into a definitive loan agreement (the "HSBC Loan Agreement 2024") with HSBC Bank.

The HSBC Loan Agreement 2024 includes other customary affirmative and negative covenants, including payment and covenant events of default. Interest Rate Swap Concurrently with the issuance of the HSBC Bank 2024 Loan, the Company entered into a long-term interest rate swap ("IRS") transaction with the objective of hedging the variable interest rate fluctuations related to the HSBC Bank 2024 Loan at a fixed 3-month SOFR of 3.9%. The terms of the IRS match those of the HSBC Bank 2024 Loan, including the notional amount of the principal and interest payment dates. The Company designated the IRS as a cash flow hedge as per ASC 815, Derivatives and Hedging, and accordingly will measure the IRS instrument at fair value. The changes in the IRS fair value will initially be recorded in Other Comprehensive Income (Loss) and reclassified to Interest expense, net in the same period or periods during which the hedged transaction affects earnings. The hedged transaction and the IRS effect in earnings are presented in the same line item in the consolidated statements of operations and comprehensive income.
