Funding Arrangements	Note 4. Funding Arrangements NIAID Contract In September 2022, the Company received a cost-reimbursement contract award from the NIAID to support preclinical, Phase 1 studies and other activities to enable the advancement of epetraborole into late-stage development for acute systemic melioidosis and other biothreat pathogens. The Company is eligible to receive up to $17.8 million in funding over a total term of 48 months, consisting of a base period and seven option periods. In July 2023 and May 2024, the NIAID exercised two of seven available options under the NIAID contract (No: 75N93022C00059), resulting in an increase in committed contract funding of $0.7 million and $3.8 million, respectively, for a cumulative total of $8.8 million. Funding for these options extends the estimated completion of the current contract by 29 months beyond the base period of 18 months to August 2026. As of September 30, 2024, a total of $8.8 million of funding for the 18-month base period plus an additional 29 months for a total of 47 months has been committed. As of September 30, 2024 and December 31, 2023, the Company had recorded a receivable of $0.7 million and $0.4 million, respectively, which was included in prepaid expenses and other current assets on the balance sheets. During the three and nine months ended September 30, 2024, the Company recorded $0.7 million of income under the NIAID contract as a reduction in research and development operating expenses. During the three and nine months ended September 30, 2023, the Company recorded zero income under the NIAID contract as a reduction in research and development operating expenses. UGARF Grant In September 2022, the Company entered into a subcontract agreement with the UGARF to conduct preclinical activities on behalf of UGARF (“UGARF Agreement”). The UGARF reimburses the Company under an award from Wellcome. The Company is eligible to receive up to $1.4 million from the UGARF to support preclinical development of a boron-containing small molecule for Chagas disease. In July 2024, the Company signed an amendment to the UGARF Agreement for additional funding in the amount of $0.2 million. As of September 30, 2024 and December 31, 2023, the Company had recorded a grant receivable of zero and $0.6 million, respectively, which was included in prepaid expenses and other current assets on the balance sheets. During the three and nine months ended September 30, 2024, the Company recorded income of zero and $0.1 million, respectively, as a reduction in research and development operating expenses under the UGARF Agreement. During the three and nine months ended September 30, 2023, the Company recorded income of $0.4 million and $0.7 million, respectively, as a reduction in research and development operating expenses under the UGARF Agreement. BMGF Grants In September 2023, the Company received a cost-reimbursement contract award from the Bill and Melinda Gates Foundation (“2023 BMGF Agreement”) under which the Company was awarded $1.8 million to support the discovery of novel, boron containing small molecules for the treatment of tuberculosis and malaria. The Company is required to apply the funds it receives under the 2023 BMGF Agreement solely toward direct costs related to this research program. The Company received $1.0 million of funding in advance and tracks and reports eligible expenses incurred to the BMGF.

Any unspent funds and any funds spent that have not yet been incurred are recorded as part of other current liabilities on the balance sheets. In September 2024, the Company entered into a second-year continuation cost-reimbursement contract award with the Bill and Melinda Gates Foundation (“2024 BMGF Agreement”) under which the Company was awarded $2.0 million to support an early-stage research program focused on delivering novel leads as starting points for new drugs that can be combined to deliver shorter, safer and simpler TB drug regimens. The Company is required to apply the funds it receives under the 2024 BMGF Agreement solely toward direct costs related to this research program. The Company received $1.1 million of funding in advance and tracks and reports eligible expenses incurred to the BMGF. Any unspent funds and any funds spent that have not yet been incurred are recorded as part of other current liabilities on the balance sheets.
