Item 1.01 Entry into a Material Definitive Agreement.

On September 3, 2025 (the “Effective Date”), Senseonics Holdings, Inc. (the “Company”) and Senseonics, Incorporated, a wholly-owned subsidiary of the Company (“Senseonics, Inc.” and together with the Company, “Senseonics”) entered into a First Amendment to Loan and Security Agreement with the several financial institutions or entities party thereto (collectively, the “Lenders”) and Hercules Capital, Inc., a Maryland corporation (the “Agent”), in its capacity as administrative agent and collateral agent for itself and the Lenders, which amends the Company’s existing Loan and Security Agreement, dated as of September 8, 2023 (the “Existing Loan Agreement” and as amended, the “Amended Loan Agreement”), by and among the Company, Senseonics Inc., certain of the Lenders and the Agent. Pursuant to the Amended Loan Agreement, the Lenders have agreed to make available to Senseonics up to $100.0 million in senior secured term loans, consisting of (i) an initial term loan of $35.0 million, which was funded on the Effective Date to refinance the outstanding term loans under the Existing Loan Agreement and (ii) three additional tranches of term loans in the amounts of up to $10.0 million (the “Tranche 2 Loan”), $20.0 million (the “Tranche 3 Loan”) and uncommitted $35.0 million (the “Tranche 4 Loan”), respectively, which will become available to Senseonics upon Senseonics’ satisfaction of certain terms and conditions set forth in the Amended Loan Agreement. The loans under the Amended Loan Agreement mature on September 3, 2029 (the “Maturity Date”).

The loans under the Amended Loan Agreement bear interest at an annual rate equal to the greater of (i) the prime rate as reported in The Wall Street Journal plus 2.40% and (ii) 9.90%. Borrowings under the Amended Loan Agreement are repayable in monthly interest-only payments through (a) initially, September 30, 2027, (b) if Senseonics satisfies the 2025 Tranche 2 Milestone (as defined in the Amended Loan Agreement), October 1, 2028 and (c) if Senseonics satisfies the 2025 Tranche 3 Milestone (as defined in the Amended Loan Agreement), the Maturity Date. After the interest-only payment period, borrowings under the Amended Loan Agreement are repayable in equal monthly payments of principal and accrued interest until the Maturity Date.

At Senseonics’ option, Senseonics may prepay all or any portion of the outstanding borrowings under the Amended Loan Agreement, subject to a prepayment fee equal to (a) 3.0% of the principal amount being prepaid if the prepayment occurs within one year of the Effective Date, 2.0% of the principal amount being prepaid if the prepayment occurs during the second year following the Effective Date, and 1.00% of the principal amount being prepaid if the prepayment occurs more than two years after the Effective Date and prior to the Maturity Date. In addition, Senseonics paid a $412,500 facility fee upon closing of the Amended Loan Agreement and will pay additional facility fees in the amount of 0.50% of any drawn Tranche 2 Loan or Tranche 3 Loan or in the amount of 1.00% of any drawn Tranche 4 Loan. The Amended Loan Agreement also provides for an end of term fee in an amount equal to 6.95% of the aggregate principal amount of loans actually made under the Amended Loan Agreement, which fee is due and payable on the earliest to occur of (i) the Maturity Date, (ii) the date Senseonics prepays the outstanding loans in full, and (iii) the date that the secured obligations become due and payable. In the event the loans are prepaid or repaid during the first year or second year following the Effective Date, such end of term fee will be reduced to 3.95% or 4.95%, respectively, of the aggregate principal amount of loans actually made under the Amended Loan Agreement. Such end of term fee is in addition to any end of terms fee accrued under the Existing Loan Agreement.

The obligations of the Company and Senseonics Inc. under the Amended Loan Agreement are secured, by a first-priority security interest in substantially all of their assets. The Amended Loan Agreement contains a minimum cash covenant that requires Senseonics to hold unrestricted cash equal to specified percentage of the outstanding loan amount under the Amended Loan Agreement. The Amended Loan Agreement also contains a performance covenant, commencing on January 1, 2026, that requires Senseonics to generate net product revenue on a trailing six-month basis in excess of specified percentage for applicable measuring periods. Compliance with the minimum cash covenant and performance covenant may be waived subject to satisfaction of certain terms and conditions set forth in the Amended Loan Agreement.

In addition, the Amended Loan Agreement contains customary representations and warranties and customary affirmative and negative covenants, including, among other things, restrictions on indebtedness, liens, investments, mergers, corporate changes, dispositions, prepayment of other indebtedness, and dividends and other distributions, subject to certain exceptions. The Amended Loan Agreement also contains events of default including, among other things, payment defaults, breach of covenants, material adverse effect, breach of representations and warranties, cross-default to material indebtedness, bankruptcy-related defaults, judgment defaults, revocation of certain government approvals, and the occurrence of certain adverse events. Following an event of default and any applicable cure period, a default interest rate equal to the then-applicable interest rate plus 4.0% may be applied to the outstanding amount, and the Lenders will have the right to accelerate all amounts outstanding under the Amended Loan Agreement, in addition to other remedies available to them as secured creditors of the Company and Senseonics, Inc.

In connection with the entry into the Amended Loan Agreement, the Company amended the warrants previously issued to certain of the Lenders under the Existing Loan Agreement collectively exercisable for an aggregate of 1,180,249 shares of the Company’s common stock (the “Existing Warrants”), pursuant to which the exercise price of such Existing Warrants has been reduced to $0.4545 per share. Pursuant to the Amended Loan Agreement, the Company also agreed to issue additional warrants (the “Additional Warrants”) in substantially the same form as the Existing Warrants upon the funding of the Tranche 2 Loan, Tranche 3 Loan and Tranche 4 Loan. The Additional Warrants may be exercised through the earlier of (i) the seventh anniversary of the applicable issuance date and (ii) the consummation of certain acquisition transactions involving the Company, as set forth in such Additional Warrants. The number of shares of the Company’s common stock for which the Additional Warrants are exercisable and the associated exercise price are subject to certain customary proportional adjustments for fundamental events, including stock splits and reverse stock splits, as set forth in the Additional Warrants. The Additional Warrants would be exercisable for an aggregate number of shares of the Company’s common stock equal to 2.0% of the funded loan amount divided by the exercise price equal to the three-day volume-weighted average price of the Company’s common stock prior to the issuance date of such Additional Warrants.

The foregoing descriptions of the Amended Loan Agreement and the Additional Warrants contained herein do not purport to be complete and are qualified in their entirety by reference to the full text of the Amended Loan Agreement, which is filed herewith as Exhibit 10.1, and the form of Warrant Agreement, which was filed as Exhibit 10.2 to the Form 8-K filed by the Company on September 11, 2023, and incorporated herein by reference.

On September 3, 2025, the Company and Ascensia Diabetes Care Holdings AG (“Ascensia” and together with the Company, the “Parties”) entered into a Memorandum of Understanding (the “MOU”) related to the transfer of commercial operations relating to the Eversense product from Ascensia back to the Company, including the proposed termination, orderly unwinding of, and smooth transition from the commercial relationship between the Company and Ascensia (the “Proposed Transition”), which is contemplated to involve the termination of that certain Collaboration and Commercialization Agreement, dated August 9, 2020, between Ascensia and Senseonics, as amended to date (the “Collaboration Agreement”), including all agreements entered into between the Parties pursuant to the terms and conditions thereof or in connection therewith (collectively, the “Agreements”). Pursuant to the MOU, the Parties have agreed to use commercially reasonable efforts to negotiate and execute definitive agreement(s) (“Definitive Agreement”) governing the Proposed Transition by October 31, 2025.

Pursuant to a Definitive Agreement to be negotiated, it is contemplated that Ascensia would agree to assign, convey and transfer to Senseonics all of its right, title and interest in and to agreed-upon assets related to Ascensia’s Eversense business that were created and/or conceived under the Agreements and as identified in the MOU (the “Transferred Assets”) at a sale price equal to Ascensia’s book value of such assets. The Parties anticipate the transfer of (a) the Transferred Assets relating to the Eversense business in the United States would occur upon the closing of the transactions contemplated by the Definitive Agreement on January 1, 2026, or such other date as agreed by the Parties, and (b) the Transferred Assets relating to the Eversense business outside of the United States would occur following the closing of the transactions contemplated by the Definitive Agreement on a timeline to be agreed between the Parties, provided that the Parties desire to target such closings to occur on January 1, 2026, if possible. The MOU contemplates that the Definitive Agreement will provide for the provision of transition services by Ascensia to support the establishment of Senseonics’ commercial functions and achieve a smooth transition of the activities to those functions, the pricing and related terms of which are to be finalized by the Parties in the definitive agreements. It is contemplated that the Definitive Agreement would contain such covenants, conditions, releases (including but not necessarily limited to reciprocal releases acceptable to both Parties covering all claims under the Agreements), indemnities, representations and warranties as are customary for this type of transaction and as the Parties would mutually agree.

Chief Commercial Officer

On September 3, 2025 in connection with the MOU, the Company’s board of directors approved the appointment of Brian Hansen, Ascensia’s President of CGM and a Senseonics director, to serve as the Company’s Chief Commercial Officer effective January 1, 2026 or such other date as agreed by the Company and Mr. Hansen.
