The Company enters into a number of manufacturing commitments for the future purchase of materials and contract manufacturing services. While the majority of such contracts can be cancelled on reasonable notice, due to the significant ongoing expenditure associated with the Company’s programs, including brenetafusp, the Company estimates it has noncancellable commitments in relation to the development and supply of product candidates totaling $27.5 million, the majority of which are estimated to be paid within twelve months from the balance sheet date.

Under the terms of the Company’s agreement with the Gates Foundation, the Company is required to develop, manufacture and commercialize soluble TCR bispecific therapeutic candidates targeted to mutually agreed neglected diseases, currently HIV, with the potential to treat people at an affordable price in developing countries. In the event of certain defaults by the Company under the agreement, which the Company considers to be within its control, the Gates Foundation has the right to sell, or require the Company to buy back, any of the shareholdings in the Company held by the Gates Foundation. In such an event, if within 12 months after such redemption or sale, the Company experiences a change in control at a valuation of more than 150% of the valuation used for the redemption or the sale of the shares, the Company has agreed to pay the Gates Foundation compensation equal to the excess of what it would have received in such transaction if it still held its shares at the time of such change of control over what it received in the sale or redemption of its shares.
