Item 1.01. Entry into a Material Definitive Agreement.

On April 27, 2023 (the “Closing Date”), Seres Therapeutics, Inc., a Delaware corporation (the “Company”) entered into a Credit Agreement and Guaranty (the “Credit Agreement”), among the Company, the subsidiary guarantors from time to time party thereto, the lenders from time to time party thereto (the “Lenders”), and Oaktree Fund Administration, LLC, in its capacity as administrative agent for the Lenders (in such capacity, the “Agent”). The Credit Agreement establishes a term loan facility of $250 million, consisting of (i) $110 million (the “Tranche A Loan”) funded on the Closing Date, (ii) $45 million (the “Tranche B Loan”) that the Company may borrow subject to certain conditions, (iii) $45 million (the “Tranche C Loan”) that the Company may borrow subject to certain conditions, and (iv) $50 million (the “Tranche D Loan”) available in Oaktree’s sole discretion (collectively with the Tranche A Loan, the Tranche B Loan, the Tranche C Loan, and the Tranche D Loan, the “Term Loan”); provided, in the case of the Tranche B Loan and the Tranche C Loan, that the Company and its subsidiaries have achieved certain VOWST^TM (SER-109) net sales targets. The Term Loan has a maturity date of April 27, 2029 (the “Maturity Date”). The Company expects net proceeds from the Tranche A Loan of approximately $50 million, after deducting approximately $53 million to repay its existing credit facility with Hercules Capital, Inc. and estimated expenses and fees.

Borrowings under the Term Loan will bear interest at a rate per annum equal to three-month term Secured Overnight Financing Rate (subject to a 2.500% floor and a 5.000% cap), plus an applicable margin of 7.875%, payable quarterly in arrears. If certain VOWST net sales targets are met, the applicable margin shall be reduced from 7.875% to 7.50% through the Maturity Date. The Company is permitted to make quarterly interest-only payments on the Term Loan for the first three years after the Closing Date. Beginning on June 30, 2026, the Company will be required to make quarterly payments of interest, plus repay 7.5% of the outstanding principal of the Term Loan in quarterly installments until the Maturity Date, unless the interest only period is extended based upon the achievement of certain VOWST net sales targets.

The Company is obligated to pay the Lenders an exit fee equal to 1.50% of the aggregate amount of the Term Loan funded, such exit fee to be due and payable upon the earliest to occur of (1) the Maturity Date, (2) the acceleration of the outstanding Term Loan, and (3) the prepayment of the outstanding Term Loan. The Company may voluntarily prepay the outstanding Term Loan, subject to a customary make-whole for the first two years following the Closing Date plus 4.0% of the principal amount of the Term Loan prepaid, and thereafter a prepayment premium equal to (i) 4.0% of the principal amount of the Term Loan prepaid, if prepaid after the second anniversary of the Closing Date through and including the third anniversary of the Closing Date, (ii) 2.0% of the principal amount of the Term Loan if prepaid after the third anniversary of the Closing Date through and including the fourth anniversary of the Closing Date, (iii) 1.0% of the principal amount of the Term Loan if prepaid after the fourth anniversary of the Closing Date through and including the fifth anniversary of the Closing Date, with no prepayment premium due after the fifth anniversary of the Closing date through the Maturity Date.

The Company’s obligations under the Credit Agreement and the other Loan Documents (as defined in the Credit Agreement) will be guaranteed by any domestic subsidiaries of the Company that become Guarantors (as defined in the Credit Agreement), subject to certain exceptions. The Company’s and the Guarantors’ (collectively, the “Loan Parties”) respective obligations under the Credit Agreement and the other Loan Documents are secured by first priority security interests in substantially all assets of the Loan Parties, including intellectual property, subject to certain customary thresholds and exceptions. As of the Closing Date, there are no Guarantors.

The Credit Agreement contains customary representations, warranties and affirmative and negative covenants, including a financial covenant requiring the Company to maintain certain levels of cash and cash equivalents in accounts subject to a control agreement in favor of the Agent of at least $30 million at all times commencing from 30 days after the Closing Date and decreasing to $25 million of cash and cash equivalents in such controlled accounts after the Company borrows any Tranche B Loan.

In addition, the Credit Agreement contains certain events of default that entitle the Agent to cause the Company’s indebtedness under the Credit Agreement to become immediately due and payable, and to exercise remedies against the Loan Parties and the collateral securing the Term Loan, including cash. Under the Credit Agreement, an event of default will occur if, among other things, the Company fails to make payments under the Credit Agreement (subject to specified periods), the Company or its subsidiaries breach any of the covenants under the Credit Agreement (subject to specified cure periods with respect to certain breaches), a material adverse change occurs, the Company,

its subsidiaries or their respective assets become subject to certain legal proceedings, such as bankruptcy proceedings, the Company and/or its subsidiaries are unable to pay their debts as they become due or default on contracts with third parties which would permit the holder of indebtedness in excess of a certain threshold to accelerate the maturity of such indebtedness or that could cause a material adverse change. Upon the occurrence and for the duration of an event of default, an additional default interest rate equal to 2.0% per annum may apply to all obligations owed under the Credit Agreement.

On the Closing Date, the Company is required to issue to the Lenders of such Term Loan warrants to purchase 647,589 shares (subject to certain adjustments) of the Company’s common stock (the “Warrant”), at an exercise price per share of $6.69. Upon the funding of each of the Tranche B Loan and the Tranche C Loan, the Company is required to issue to the Lenders of the Term Loan additional warrants to purchase 264,922 shares (subject to certain adjustments) of the Company’s common stock on each such funding date at an exercise price equal to the trailing volume weighted average price of the Company’s common stock for the 30 trading days prior to the funding date for each tranche. The Warrants are immediately exercisable, and the exercise period will expire seven years from the date of issuance.

The Credit Agreement is filed as Exhibit 10.1 to this Current Report on Form 8-K (the “Current Report”) and the Form of Warrant is filed as Exhibit 4.1 to this Current Report, each of which is incorporated herein by reference. The description of the Credit Agreement and the Warrants is a summary only, does not purport to be complete, and is qualified in its entirety by the terms of the Credit Agreement and the Form of Warrant.

Item 2.02 Results of Operations and Financial Condition.

Based upon preliminary estimates and information available to us as of the date of this Current Report, we expect to report that we had approximately $107 million of cash and cash equivalents and marketable securities as of March 31, 2023.

This estimate of our cash and cash equivalents and marketable securities as of March 31, 2023 is preliminary and is subject to change upon completion of our financial statement closing procedures. There can be no assurance that our final cash position as of March 31, 2023 will not differ from this estimate, including as a result of adjustments as a result of our review, and any such change could be material. Our independent registered public accountants have not audited, reviewed or performed any procedures with respect to such preliminary financial data and accordingly do not express an opinion or any other form of assurance with respect to such data. Complete results will be included in our Quarterly Report on Form 10-Q for the three months ended March 31, 2023.

The form of Warrant is filed as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated by reference herein.
