We believe that our existing cash, cash equivalents and investments on hand as of September 30, 2023, will enable us to meet our operational liquidity needs and fund our planned investing activities for the next 12 months. We have based our liquidity and cash flow projections on assumptions that may prove to be incorrect, and we could use our capital resources sooner than we expect.
Term Loan A Credit Agreement
On July 26, 2023, we entered into a Credit Agreement (the “TLA Credit Agreement”) with JPMorgan Chase Bank, N.A., as “Administrative Agent”, and certain lenders. The TLA Credit Agreement provides for a five-year senior secured term loan (the “TLA Term Loan”) in an aggregate principal amount of $185.0 million.
On September 21, 2023, we entered into the First Incremental Amendment (the “First Incremental Amendment”) with the Administrative Agent and Bank of America, N.A., as incremental lender. The First Incremental Amendment provides for an incremental senior secured term loan (the “Incremental Term Loan”) in an aggregate principal amount of $15.0 million. The First Incremental Amendment amends the TLA Credit Agreement and provides that the Incremental Term Loan will have identical terms as the TLA Term Loan.
The repayment schedule for both the TLA Term Loan and the Incremental Term Loan (together, the “Term Loans”) consists of $3.8 million quarterly principal payments, which commence on December 31, 2023, increasing to $5.0 million quarterly principal payments beginning on December 31, 2025, with a $115.0 million payment due on the maturity date of July 26, 2028. The Term Loans bear interest at a per annum rate equal to, at our option, (i) a base rate plus a specified margin ranging from 2.50% to 3.00%, based on our senior secured net leverage ratio (as defined in the TLA Credit Agreement) or (ii) Term SOFR plus a credit spread adjustment of 0.10% plus a specified margin ranging from 3.50% to 4.00%, based on our senior secured net leverage ratio.
The TLA Credit Agreement contains customary affirmative and negative covenants, financial covenants, representations and warranties, events of default and other provisions. We were in compliance with all covenants as of September 30, 2023.
Blackstone Credit Agreement
In August 2021, we entered into the Blackstone Credit Agreement that provided for (i) a senior secured term loan facility in an aggregate original principal amount of $200.0 million (the “Initial Term Loan”) and (ii) a senior secured delayed draw term loan facility in an aggregate principal amount up to $100.0 million (the “DDTL” and, together with the Initial Term Loans, the “Loans”). The DDTL was initially available to draw down through August 9, 2022. In August 2022, we entered into an agreement to extend the expiration date of the DDTL to August 9, 2023, for which we paid a ticking fee at a rate of 1% per annum on the undrawn portion of the DDTL, which commenced on August 10, 2022. We used substantially all of the proceeds from the Blackstone Credit Agreement, and the related sale of our common stock, to repay the balance of the OrbiMed Credit Agreement.
In connection with the TLA Credit Agreement, we extinguished the Blackstone Credit Agreement, which required a payoff amount of $207.3 million consisting of principal repayment, interest, exit fees, a ticking fee and a prepayment premium. We recognized a loss on extinguishment of debt of $9.8 million relating to the Blackstone Credit Agreement for the three and nine months ended September 30, 2023.
Share Repurchases
On August 1, 2023, our Board of Directors approved a program providing for the repurchase of shares of common stock in an aggregate amount of up to $125.0 million, excluding commissions and transaction fees. The repurchase program may be suspended, terminated or modified at any time for any reason. During the three and nine months ended September 30, 2023, we repurchased and cancelled 1,439,792 shares of common stock at an aggregate cost of $50.0 million, excluding commissions and transaction fees. As of September 30, 2023 the remaining amount of common stock authorized for repurchases was $75.0 million.
