In December 2025, the Group entered into a new $125.0 million five-year credit-line facility provided by Dr Gregory George, a non-executive director of Mesoblast Limited. The Group drew the first tranche of $75.0 million on closing in December 2025. In June 2026, the Group drew the second tranche of $50.0 million from the existing credit-line facility. The credit-line facility has a five year interest only period, at a fixed rate of 8.00% per annum, payable quarterly, and is secured solely with the TEMCELL royalty. Refer to Note 5(e)(i) for more details on the credit-line facility.
As part of the credit-line facility, warrants were granted to purchase 3,225,756 shares or 322,576 ADSs under a 1‑for‑10 ADS ratio, at A$3.20 per share, a 15% premium to the 30-day VWAP, with the ADS price calculated using the USD spot rate at the time of exercise. The loan proceeds were first allocated to the issue of warrants at fair value of $4.0 million (A$5.9 million), with the remainder to the credit-line facility. The Group has determined that an obligation to issue the warrants has arisen from the time the credit-line facility was signed; consequently, a liability for the warrants was recognized. Refer to Note 5(f)(vi) for more details on the warrants issued.
