On February 27, 2026 (the “Signing Date”), the Company entered into a Loan Agreement (the “Loan Agreement”), among Blackstone Alternative Credit Advisors LP and Blackstone Life Sciences Advisors L.L.C. (collectively referred to herein as “Blackstone”), certain subsidiaries of the Company party thereto as guarantors (collectively, the “Guarantors”), Wilmington Trust, National Association, as Agent and the lenders from time to time party thereto (collectively, the “Lenders”).

The Loan Agreement provides for a term loan in an aggregate principal amount of $100.0 million (the “Term Loan”), which was funded to the Company on February 27, 2026 (the “Closing Date”). The Term Loan bears interest at a rate equal to the Term SOFR adjusted secured overnight financing rate plus a margin of 4.50%. The Term Loan includes a SOFR floor of 1.50%. If an event of default occurs and is continuing, all amounts outstanding under the Loan Agreement will bear additional interest at a per annum rate equal to 2.00% plus the rate otherwise applicable to the Term Loan. The Term Loan will mature and the principal

amount (including any interest and fees) must be repaid on the date that is five years from the Closing Date. The Term Loan is subject to mandatory prepayment provisions that may require prepayment upon a change of control, the incurrence of certain additional indebtedness, certain asset sales, or an event of loss, subject to certain conditions set forth in the Loan Agreement. The Company may prepay the Term Loan in whole or in part at its option at any time. Any prepayment of the Term Loan is subject to certain yield protection premiums. The Company’s net proceeds from the Term Loan were $97.0 million, after deducting debt issuance costs and expenses.

The obligations under the Loan Agreement are guaranteed by the Guarantors and secured by a first lien security interest in substantially all assets of the Company and Guarantors. The Loan Agreement contains certain customary representations and warranties, affirmative and negative covenants and events of default applicable to the Company and the Guarantors. The Loan Agreement also contains a minimum liquidity covenant of $50.0 million effective following the Closing Date. If an event of default occurs and is continuing, the Lenders may declare all amounts outstanding under the Loan Agreement to be immediately due and payable.

On August 3, 2026, the Company entered into an Amended and Restated Loan Agreement (the “Amended Loan Agreement”) with Blackstone, the Guarantors, and the Lenders. The Amended Loan Agreement amends and restates the Company’s existing Loan Agreement and provides for an additional $50.0 million term loan facility, bringing the aggregate principal amount available under the facility to $150.0 million. The proceeds of the additional term loan are being used for general corporate purposes and to pay fees and expenses associated with the financing.

Amounts outstanding under the incremental term loan facility bear interest at a rate equal to Term SOFR plus 5.50%, subject to a 1.50% SOFR floor. The term loans mature five years following the February 2026 Closing Date and are subject to customary mandatory and voluntary prepayment provisions, including applicable prepayment premiums. The Company’s obligations under the Amended Loan Agreement are guaranteed by certain of its subsidiaries and secured by a first-priority lien on substantially all of the assets of the Company and the Guarantors. The Amended Loan Agreement contains customary affirmative and negative covenants, events of default and minimum liquidity requirements, including a requirement that the Company maintain minimum liquidity of $75.0 million.

On August 3, 2026, concurrently with the execution of the Amended Loan Agreement, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain affiliates of Blackstone (collectively, the “Investors”), pursuant to which the Investors agreed to purchase approximately $5.0 million of the Company’s Class A common stock in a private placement transaction.

Pursuant to the Purchase Agreement, the Company agreed to issue and sell to the Investors 81,967 shares of Class A common stock at a purchase price of $61.00 per share, for aggregate gross proceeds of approximately $5.0 million. The closing of the private placement occurred on August 7, 2026, substantially concurrently with the funding of the incremental term loan facility.

On February 27, 2026, the Company repaid in full all outstanding obligations under its Credit Agreement and Guaranty (the “Credit Agreement”) with Perceptive Credit Holdings IV, LP. The aggregate payoff amount of approximately $54.5 million included: (i) $50.0 million of outstanding principal, (ii) a prepayment premium of $4.0 million, and (iii) remaining accrued interest, legal and administrative fees of $0.5 million. Upon the receipt of the payoff amount, the Credit Agreement was terminated, and all security interests and liens on the Company’s assets were released.

For the nine months ended September 30, 2026, the Company expensed $6.6 million to write off the prepayment premium and all remaining unamortized deferred financing fees associated with the Credit Agreement and reported these aggregate charges as a loss on extinguishment of debt within the condensed consolidated statement of operations.

During the first quarter of 2026, the Company reached an agreement with the Connecticut Department of Economic and Community Development (“DECD”) and repaid the remaining outstanding balance associated with the loan funding commitment from the DECD to the Company (the “DECD Loan Agreement”), which totaled $4.5 million. Upon the receipt of the payoff amount, the DECD Loan Agreement was terminated, and all security interests and liens on the Company’s assets were released.
