Notes to Unaudited Condensed Consolidated Financial Statements

1.	Organization and Nature of Operations

Senseonics Holdings, Inc., a Delaware corporation, is a medical technology company focused on the development and manufacturing of long-term, implantable continuous glucose monitoring (“CGM”) systems to improve the lives of people with diabetes by enhancing their ability to manage their disease with relative ease and accuracy.

Senseonics, Incorporated is a wholly owned subsidiary of Senseonics Holdings, Inc. and was originally incorporated on October 30, 1996 and commenced operations on January 15, 1997. Senseonics Holdings, Inc. and Senseonics, Incorporated are hereinafter collectively referred to as the “Company” unless otherwise indicated or the context otherwise requires.

2.	Liquidity and Capital Resources

From its founding in 1996 until 2010, the Company has devoted substantially all of its resources to researching various sensor technologies and platforms. Beginning in 2010, the Company narrowed its focus to developing and refining a commercially viable glucose monitoring system. The Company has incurred substantial losses and cumulative negative cash flows from operations since its inception in October 1996 and expects to incur additional losses in the near future. We incurred total gross profit (loss) of $2.7 million, ($0.8) million, and ($17.4) million for the years ended December 31, 2022, 2021 and 2020, respectively. For the three months ending June 30, 2023, the Company had gross profit of $0.4 million and an accumulated deficit of $828.0 million. To date, the Company has funded its operations principally through the issuance of preferred stock, common stock, warrants, convertible notes and debt. As of June 30, 2023, the Company had cash, cash equivalents and marketable securities of $125.1 million.

On August 10, 2023 the Company entered into separate, privately negotiated exchange agreements (the “Exchange Agreements”) with a limited number of holders (the “Noteholders”) of the Company’s currently outstanding 5.25% Convertible Senior Notes due 2025 (the “2025 Notes”). Under the terms of the Exchange Agreements, the Noteholders have agreed to exchange with the Company (the “Exchanges”) up to $30.8 million in aggregate principal amount of the Company’s outstanding 2025 Notes (the “Exchanged Notes”) for a combination of $7.5 million of cash and newly issued shares of common stock (the “Exchange Shares”). The Exchanged Notes are presently convertible into an aggregate of approximately 23.3 million shares of common stock. The number of Exchange Shares to be issued to the Noteholders will be determined based upon the volume-weighted average price per share of the common stock during a 15-day averaging period commencing on August 11, 2023. The maximum number of Exchange Shares that may be issued is 10% of the Company’s common stock outstanding as of August 10, 2023 (the “Exchange Share Cap”). If the average trading price over the averaging period would otherwise result in the number of shares to be issued exceeding the Exchange Share Cap, the amount of the Exchanged Notes will be proportionally reduced. The Exchanges are subject to customary closing conditions and are expected to close on or about September 5, 2023.

In August 2023, the Company entered into an Equity Distribution Agreement (the “Equity Distribution Agreement”) with Goldman Sachs & Co. LLC (“GS”), under which the Company could offer and sell, from time to time, at its sole discretion, shares of its common stock having an aggregate offering price of up to $106.6 million through GS as its sales agent in an “at the market” offering. GS will receive a commission up to 3.0% of the gross proceeds of any common stock sold through GS under the Equity Distribution Agreement. The shares will be offered and sold pursuant to a shelf registration statement on Form S-3 (the “Registration Statement”), filed with the Securities and Exchange Commission (the “Commission”) on August 10, 2023. The Registration Statement has not yet been declared effective by the Commission and no sales may be made until such time as the Registration Statement is declared effective.

In November 2021, the Company entered into an Open Market Sale Agreement, (the “2021 Sales Agreement”) with Jefferies LLC (“Jefferies”), under which the Company could offer and sell, from time to time, at its sole discretion, shares of its common stock having an aggregate offering price of up to $150.0 million through Jefferies as its sales agent in an “at the market” offering. Jefferies will receive a commission up to 3.0% of the gross proceeds of any common

stock sold through Jefferies under the 2021 Sales Agreement. During the six months ended June 30, 2023, the Company received $7.4 million in net proceeds from the sale of 9,944,663 shares of its common stock under the 2021 Sales Agreement. For the six months ended June 30, 2022, Company received $8.0 million in net proceeds from the sale of 3,077,493 shares of its common stock under the 2021 Sales Agreement. On August 7, 2023, the Company and Jefferies mutually agreed to terminate the Open Market Sale Agreement, effective as of August 7, 2023. At the time of termination, approximately $106.6 million remained available for issuance pursuant to the 2021 Sales Agreement.

On November 9, 2020, the Company entered into an Equity Line Agreement (the “Equity Line Agreement”) with Energy Capital, LLC, a Florida limited liability company (“Energy Capital”), which provided that, upon the terms and subject to the conditions and limitations set forth therein, Energy Capital was committed to purchase up to an aggregate of $12.0 million of shares of the Company’s newly designated series B convertible preferred stock (the “Series B Preferred Stock”) at the Company’s request from time to time during the 24-month term of the Equity Line Agreement. Under the Equity Line Agreement, beginning January 21, 2021, subject to the satisfaction of certain conditions, including that the Company have less than $8.0 million of cash, cash equivalents and other available credit (aside from availability under the Equity Line Agreement), the Company had the right, at its sole discretion, to present Energy Capital with a purchase notice (each, a “Regular Purchase Notice”) directing Energy Capital (as principal) to purchase shares of Series B Preferred Stock at a price of $1,000 per share (not to exceed $4.0 million worth of shares) once per month, up to an aggregate of $12.0 million of the Company’s Series B Preferred Stock at a per share price (the “Purchase Price”) equal to $1,000 per share of Series B Preferred Stock, with each share of Series B Preferred Stock initially convertible into common stock, beginning six months after the date of its issuance, at a conversion price of $0.3951 per share, subject to customary anti-dilution adjustments, including in the event of any stock split. The Equity Line Agreement provided that the Company was not permitted to affect any Regular Purchase Notice under the Equity Line Agreement on any date where the closing price of the Company’s common stock on the NYSE American is less than $0.25 without the approval of Energy Capital. In addition, beginning on January 1, 2022, since there had been no sales of the Series B Preferred Stock pursuant to the Equity Line Agreement, Energy Capital had the right, at its sole discretion, by its delivery to the Company of a Regular Purchase Notice, to purchase up to the $12.0 million of Series B Preferred Stock under the Equity Line Agreement at the Purchase Price. On November 7, 2022, Energy Capital exercised in full its right to purchase $12.0 million of Series B Preferred Stock. The excess of the Purchase Price and the fair value of the Energy Capital option in the total amount of $37.6 million was recorded in additional-paid-in-capital.

On August 9, 2020, the Company entered into a financing agreement with the parent company of Ascensia Diabetes Care Holdings AG (“Ascensia”), PHC Holdings Corporation (“PHC”), pursuant to which the Company issued $35.0 million in aggregate principal amount of Senior Secured Convertible Notes due on October 31, 2024 (the “PHC Notes”), to PHC. The Company also issued 2,941,176 shares of common stock to PHC as a financing fee. The Company also has the option to sell and issue PHC up to $15.0 million of convertible preferred stock on or before December 31, 2022, contingent upon obtaining U.S. Food and Drug Administration (“FDA”) approval for the 180-day Eversense product for marketing in the United States before such date. The Company successfully obtained FDA approval in February 2022 and the option was not exercised. As described in Note 11, on March 13, 2023, the Company entered into an Exchange Agreement (the “Exchange Agreement”) with PHC, pursuant to which PHC agreed to exchange (the “Exchange”) its $35.0 million aggregate principal amount of the PHC Notes, including all accrued and unpaid interest thereon, for a warrant (the “Exchange Warrant”) to purchase up to 68,525,311 shares of the Company’s common stock, $0.001 par value per share (the “Exchange Warrant Shares”). The Exchange Warrant is a “pre-funded” warrant with a nominal exercise price of $0.001 per Exchange Warrant Share. On March 31, 2023, the Exchange was consummated, and the Company issued the Exchange Warrant to PHC in consideration for the cancellation of the PHC Notes.

On March 13, 2023, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) with PHC, pursuant to which the Company issued and sold to PHC in a private placement (the “Private Placement”) a warrant (the “Purchase Warrant”) to purchase 15,425,750 shares of the Company’s common stock, $0.001 par value per share (the “Purchase Warrant Shares”). The purchase price of the Purchase Warrant was approximately $0.97 per Purchase Warrant Share, representing the undiscounted, trailing 10-day volume weighted average price of the Company’s common stock through March 10, 2023. The Purchase Warrant is a “pre-funded” warrant with a nominal exercise price of $0.001 per Purchase Warrant Share. The issuance of the Purchase Warrants enabled PHC to maintain, as of the closing of the transaction, a 15% beneficial ownership for purposes of the Investor Rights Agreement, dated August 9, 2020, between the Company and PHC. The Private Placement closed on March 13, 2023 (the “Private

3.	Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and the instructions to Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. Although the Company considers the disclosures in these unaudited consolidated financial statements to be adequate to make the information presented not misleading, certain information or footnote information normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted under the rules and regulations of the SEC. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of financial position at June 30, 2023, and December 31, 2022, results of operations, comprehensive income (loss), and changes in stockholder’s deficit for the three and six months ended June 30, 2023 and 2022 and cash flows for the six months ended June 30, 2023 and 2022 have been included. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 16, 2023. The interim results for June 30, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023, or for any future interim periods.

The consolidated financial statements reflect the accounts of Senseonics Holdings, Inc. and its wholly owned operating subsidiary Senseonics, Incorporated. The Company views its operations and manages its business in one segment, glucose monitoring products. Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance.

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires entities to record expected credit losses for certain financial instruments, including trade receivables, as an allowance that reflects the entity's current estimate of credit losses expected to be incurred. For available-for-sale debt securities in unrealized loss positions, the new standard requires allowances to be recorded instead of reducing the amortized cost of the investment. The Company currently holds investments in available-for-sale securities. The Company has not historically experienced collection issues or bad debts with trade receivables. Accordingly, the Company does not expect this to have a significant impact on its consolidated financial statements and related disclosures at this time. The Company adopted this guidance as of January 1, 2023 and its adoption did not have a material impact on the consolidated financial statements and related disclosures.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and expenses during the reporting period. In the accompanying unaudited consolidated financial statements, estimates are used for, but not limited to, stock-based compensation, recoverability of long-lived assets, deferred taxes and valuation allowances, fair value of investments, derivative assets and liabilities, obsolete inventory, warranty obligations, variable consideration related to revenue, bad debts, depreciable lives of property and equipment, and accruals for clinical study costs, which are accrued based on estimates of work performed under contract. The Company bases these estimates on historical and anticipated results, trends, and various other assumptions that it believes are reasonable, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities and recorded revenues and expenses. Actual results could differ from those estimates; however, management does not believe that such differences would be material.

Significant Accounting Policies

The accounting policies used by the Company in its presentation of interim financial results are consistent with those presented in Note 3 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

4. Revenue Recognition

The Company generates product revenue from sales of the Eversense system and related components and supplies to Ascensia, through a collaboration and commercialization agreement (the “Ascensia Commercialization Agreement”), third-party distributors in the European Union and to strategic fulfillment partners in the United States (collectively, the “Customers”), who then resell the products to health care providers and patients. Customers pay the Company for sales, regardless of whether or not the Customers resell the products to health care providers and patients. The Company’s policies for recognizing sales have not changed from those described in our Annual Report on Form 10-K for the year ended December 31, 2022.

Revenue by Geographic Region

The following table sets forth net revenue derived from the Company’s two primary geographical markets, the United States and outside of the United States, based on the geographic location to which the Company delivers the product, for the three and six months ended June 30, 2023 and 2022:

Total	$	3,714	100.0	%	$	6,196	100.0	%

Contract Assets

Contract assets consist of unbilled receivables from customers and are recorded at net realizable value and relate to the revenue share variable consideration from the Ascensia Commercialization Agreement. Accounts receivable – related parties, net as of June 30, 2023 and December 31, 2022, included unbilled accounts receivable of $0.9 million and $1.7 million, respectively. The Company expects to invoice and collect all unbilled accounts receivable within 12 months.

Table of Contents

Concentration of Revenue and Customers

For the three months ended June 30, 2023 and 2022, the Company derived 89% and 96%, respectively, of its total revenue from one customer, Ascensia. For the six months ended June 30, 2023, and 2022, the Company derived 91% and 93%, respectively of its total revenue from one customer, Ascensia. Revenues for these corresponding periods represent sales of sensors, transmitters and miscellaneous Eversense system components.

5. Net Income (Loss) per Share

Basic net income (loss) per share attributable to common stockholders is calculated by dividing the net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. An aggregate of 83,951,061 shares of common stock issuable upon the exercise of the Exchange Warrant Shares and the Purchase Warrant Shares held by PHC are included in the number of outstanding shares used for the computation of basic net income (loss) per share for the three and six months ended June 30, 2023. Since the shares are issuable for little or no consideration, sometimes referred to as “penny warrants”, they are considered outstanding in the context of earnings per share, as discussed in ASC 260-10-45-13.

Dilutive net income (loss) per share is computed using the weighted average number of common shares outstanding during the period and, when dilutive, potential common share equivalents. Potentially dilutive common shares consist of shares issuable from restricted stock units, stock options, warrants and the Company’s convertible notes. Potentially dilutive common shares issuable upon vesting of restricted stock units and exercise of stock options and warrants are determined using the average share price for each period under the treasury stock method. Potentially dilutive common shares issuable upon conversion of the Company’s convertible notes are determined using the if converted method. The if-converted method assumes conversion of convertible securities at the beginning of the reporting period. Interest expense, dividends, and the changes in fair value measurement recognized during the period are added back to the numerator. The denominator includes the common shares issuable upon conversion of convertible securities.

In periods of net loss, all potentially dilutive common shares are excluded from the computation of the diluted net loss per share for those periods, as the effect would be anti-dilutive.

The following table sets forth the computation of basic and diluted net income (loss) per share for the periods shown:

2024		27,362		27,277
2025		6,749		6,724
Total	$	96,640	$	96,520

The Company periodically reviews its portfolio of debt securities to determine if any investment is impaired due to credit loss or other potential valuation concerns. For debt securities where the fair value of the investment is less than the amortized cost basis, the Company assesses at the individual security level, for various quantitative factors including, but not limited to, the nature of the investments, changes in credit ratings, interest rate fluctuations, industry analyst reports, and the severity of impairment. Unrealized losses on available-for-sale securities at June 30, 2023 were not significant and were primarily due to changes in interest rates and not due to increased credit risk associated with specific securities. The Company does not intend to sell these impaired investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity.

Leases

The Company leases approximately 33,000 square feet of research and office space for its corporate headquarters under a non-cancelable operating lease. In May 2023, the Company amended our lease, extending the lease term through May 31, 2033, and obtained a tenant improvement allowance of $1.3 million. The Company accounted for the amendment as a lease modification and remeasured the ROU asset and lease liability as of the amendment date, which resulted in an increase of $2.5 million to the ROU asset, and an increase of $3.8 million to the lease liability. The Company has one option to extend the term for an additional period of five years beginning on June 1, 2033. The rent expense is recognized on a straight-line basis through the end of the lease term, excluding option renewals. The difference between the straight-line rent amounts and amounts payable under the lease is recorded as deferred rent.

Operating lease expense for the six months ended June 30, 2023 and 2022 was $0.4 million and $0.3 million, respectively.

Product Warranty Obligations

The Company provides a warranty of one year on its smart transmitters. Additionally, the Company may also replace Eversense system components that do not function in accordance with the product specifications. Estimated replacement costs are recorded at the time of shipment as a charge to cost of sales in the consolidated statement of operations and are developed by analyzing product performance data and historical replacement experience, including comparing actual replacements to revenue.

At each June 30, 2023 and December 31, 2022, the warranty reserve was $0.5 million and $0.8 million, respectively.

Notes Payable, Preferred Stock and Stock Purchase Warrants

Term Loans

PPP Loan

On April 22, 2020, the Company received $5.8 million in loan funding from the PPP pursuant to the CARES Act, as amended by the Flexibility Act, and administered by the Small Business Administration (“SBA”). The unsecured loan (the “PPP Loan”) was evidenced by the PPP Note dated April 21, 2020 (the “PPP Note”) in the principal amount of $5.8 million with Silicon Valley Bank (“SVB”).

Under the terms of the PPP Note and the PPP Loan, interest accrued on the outstanding principal at a rate of 1.0% per annum. The term of the PPP Note was two years. In April 2022, the Company repaid the outstanding principal and accrued interest in full.

Convertible Preferred Stock and Warrants

On November 9, 2020, the Company entered into the Equity Line Agreement with Energy Capital, which provides that, upon the terms and subject to the conditions and limitations set forth therein, Energy Capital is committed to purchase up to an aggregate of $12.0 million of shares of the Company’s Series B Preferred Stock at the Company’s request from time to time during the 24-month term of the Equity Line Agreement. Under the Equity Line Agreement, beginning January 21, 2021, subject to the satisfaction of certain conditions, including the Company having less than $8 million of cash, cash equivalents and other available credit (aside from availability under the Equity Line Agreement), the Company has the right, at sole discretion, to present Energy Capital with a Regular Purchase Notice directing Energy Capital (as principal) to purchase shares of Series B Preferred Stock at a price of $1,000 per share (not to exceed $4.0 million worth of shares) once per month, up to an aggregate of $12.0 million of the Company’s Series B Preferred Stock at the Purchase Price equal to $1,000 per share of Series B Preferred Stock, with each share of Series B Preferred Stock initially convertible into common stock, beginning six months after the date of its issuance, at a conversion price of $0.3951 per share, subject to customary anti-dilution adjustments, including in the event of any stock split. The Equity Line Agreement provides that the Company shall not affect any Regular Purchase Notice under the Equity Line Agreement on any date where the closing price of the Company’s common stock on the NYSE American is less than $0.25 without the approval of Energy Capital. In addition, beginning on January 1, 2022, since there have been no sales of the Series B Preferred Stock pursuant to the Equity Line Agreement, Energy Capital has the right, at its sole discretion, by its delivery to the Company of a Regular Purchase Notice, to purchase up to the $12.0 million of Series B

Table of Contents

Preferred Stock under the Equity Line Agreement at the Purchase Price. On November 7, 2022, Energy Capital exercised in full its right to purchase $12.0 million of Series B Preferred Stock.

The Company accounted for the Equity Line Agreement as a put/call option (the “Energy Capital Option”). This put/call option was classified as a liability in accordance with ASC 480, Distinguishing liabilities from equity, on the Company’s balance sheet and was recorded at the estimated fair value of $4.2 million upon issuance. The put/call option was required to be remeasured to fair value at each reporting period with the change recorded in change in fair value of derivatives that is a component of other income (expense). In connection with the execution of the Equity Line Agreement, the Company incurred $7.6 million in debt issuance costs in fiscal year 2020. The fair value of the Energy Capital Option as of December 31, 2021 was $69.4 million. The Company adjusted the Energy Capital Option to its fair value of $25.7 million on the exercise date, recognizing a fair value adjustment gain of $43.7 million.

Concurrently with entry into the Equity Line Agreement, the Company issued a warrant to Energy Capital, exercisable beginning on May 9, 2021, to purchase up to 10,000,000 shares of common stock at an exercise price of $0.3951 per share (the “Warrant”). The Warrant was exercised on a net basis in February 2022 and Energy Capital received 8,917,535 shares of common stock upon the net exercise of the Warrants.

On March 13, 2023, pursuant to the Securities Purchase Agreement with PHC, the Company issued and sold to PHC in a private placement a warrant (the “Purchase Warrant”) to purchase 15,425,750 shares of common stock (the “Purchase Warrant Shares”). The Purchase Warrant is a “pre-funded” warrant with a nominal exercise price of $0.001 per Purchase Warrant Share. On the private placement closing date, the Company received aggregate gross proceeds of $15.0 million, before deducting private placement expenses payable by the Company. All or any part of the Purchase Warrant shall is exercisable by the holder at any time and from time to time.

The Company determined that the Purchase Warrant shall be classified as equity in accordance with ASC Topic 480, Distinguishing Liabilities from Equity and ASC Topic 815. At issuance, the Company recorded the estimated fair value of the Purchase Warrant in the amount of $14.3 million as additional paid-in-capital in the Company’s consolidated balance sheets.

Because PHC was an existing stockholder of the Company at the time of the transaction, the $0.7 million excess of the purchase price over the fair value of the Purchase Warrant was recognized as an equity transaction and recorded as a capital contribution made by PHC to the Company as additional paid-in-capital in the Company’s consolidated balance sheets.

Additionally, on March 13, 2023, the Company entered into an Exchange Agreement with PHC, pursuant to which PHC agreed to exchange (the “Exchange”) its $35.0 million aggregate principal amount of the PHC Notes, including all accrued and unpaid interest thereon, for a warrant (the “Exchange Warrant”) to purchase up to 68,525,311 shares of common stock (the “Exchange Warrant Shares”). The Exchange Warrant is a “pre-funded” warrant with a nominal exercise price of $0.001 per Exchange Warrant Share. All or any part of the Exchange Warrant is exercisable by the holder at any time and from time to time. The number of Exchange Warrant Shares represents the number of shares of common stock previously issuable upon conversion of the PHC Notes, in accordance with the original terms of the notes, including a number of shares in respect of accrued and unpaid interest through the closing date, plus additional shares with a value of $675,000 reflecting a portion of the future interest payments forgone by PHC. On March 31, 2023 (6:00 am Japan Standard Time on April 1, 2023), the Exchange was consummated, and the Company issued the Exchange Warrant to PHC in consideration for the cancellation of the PHC Notes.

The Company determined that the Exchange Warrant shall be classified as equity in accordance with ASC 480 and ASC 815. At March 31, 2023, the Company recorded the estimated fair value of the Exchange Warrant in the amount of $48.6 million as additional paid-in-capital in the Company’s consolidated balance sheets.

As of June 30, 2023, the Purchase Warrant and the Exchange Warrant remained unexercised and outstanding. As they are prefunded warrants, the Company included the entirety of the warrant shares as weighted average outstanding shares in the calculation of its basic earnings per share.

Convertible Notes

PHC Notes

On August 9, 2020, the Company entered into a Note Purchase Agreement (the “Note Purchase Agreement”) with PHC, as the purchaser (together with the other purchasers from time-to-time party thereto, the “Note Purchasers”) and Alter Domus (US) LLC, as collateral agent. Pursuant to the Note Purchase Agreement, the Company borrowed $35.0 million in aggregate principal through the issuance and sale of the PHC Notes on August 14, 2020 (the “Closing Date”). The Company also issued 2,941,176 shares of its common stock, $0.001 par value per share to PHC as a financing fee (the “Financing Fee Shares”) on the Closing Date. The Financing Fee Shares are accounted for as debt discount in the amount of $1.5 million.

The PHC Notes were senior secured obligations of the Company and were guaranteed on a senior secured basis by the Company’s wholly owned subsidiary, Senseonics, Incorporated. Interest at the initial annual rate of 9.5% is payable semi-annually in cash or, at the Company’s option, payment in kind. The interest rate decreased to 8.0% in April 2022 as a result of the Company having obtained FDA approval for the 180-day Eversense E3 system for marketing in the United States. The maturity date for the PHC Notes was October 31, 2024 (the “Maturity Date”). The obligations under the PHC Notes were secured by substantially all of the Company’s and its subsidiary’s assets.

The Note Purchasers were entitled to convert the PHC Notes to common stock at a conversion rate of 1,867.4136 shares per $1,000 principal amount of the PHC Notes (including any interest added thereto as payment in kind), equivalent to a conversion price of approximately $0.53 per share, subject to specified anti-dilution adjustments, including adjustments for the Company’s issuance of equity securities on or prior to April 30, 2022 below the conversion price. In addition, following a notice of redemption or certain corporate events that occured prior to the maturity date, the Company would have been required, in certain circumstances, to increase the conversion rate for a holder electing to convert its PHC Notes in connection with such notice of redemption or corporate event. In certain circumstances, the Company would have been required to pay cash in lieu of delivering make whole shares unless the Company obtained stockholder approval to issue such shares.

Subject to specified conditions, on or after October 31, 2022, the PHC Notes would have become redeemable by the Company if the closing sale price of the common stock were to exceed 275% of the conversion price for a specified period of time and subject to certain conditions upon 10 days prior written notice at a cash redemption price equal to the then outstanding principal amount (including any payment in kind interest which has been added to such amount), plus any accrued but unpaid interest. On or after October 31, 2023, the PHC Notes would have become redeemable by the Company upon 10 days prior written notice at a cash redemption price equal to the then outstanding principal amount (including any payment in kind interest which had been added to such amount), plus any accrued but unpaid interest, plus a call premium of 130% if redeemed at least six months prior to the Maturity Date or a call premium of 125% if redeemed within six months of the Maturity Date.

The Note Purchase Agreement contained customary terms and covenants, including financial covenants, such as operating within an approved budget and achieving minimum revenue and liquidity targets, and negative covenants, such as limitations on indebtedness, liens, mergers, asset transfers, certain investing activities and other matters customarily restricted in such agreements. Most of these restrictions were subject to certain minimum thresholds and exceptions. The Note Purchase Agreement also contained customary events of default, after which the PHC Notes would have become due and payable immediately, including defaults related to payment compliance, material inaccuracy of representations and warranties, covenant compliance, material adverse changes, bankruptcy and insolvency proceedings, cross defaults to certain other agreements, judgments against the Company, change of control or delisting events, termination of any guaranty, governmental approvals, and lien priority.

The Company also had the option to sell and issue PHC up to $15.0 million of convertible preferred stock on or before December 31, 2022 (the “PHC Option”), which was initially contingent upon obtaining FDA approval for the 180-day Eversense product for marketing in the United States before such date, and which approval the Company successfully obtained in February 2022. The PHC option was not exercised and expired on December 31, 2022 and the Company recognized a loss on extinguishment of $0.1 million.

Table of Contents

The Note Purchase Agreement also contained several provisions requiring bifurcation as a separate derivative liability including an embedded conversion feature, mandatory prepayment upon event of default that constitutes a breach of the minimum revenue financial covenant, optional redemption upon an event of default, change in interest rate after PMA approval and default interest upon an event of default. On the date of issuance, the Company recorded the fair value of the embedded features in the amount of $25.8 million as a derivative liability in the Company’s consolidated balance sheets in accordance with ASC 815. The derivative was adjusted to fair value at each reporting period, with the change in the fair value recorded in change in fair value of derivatives that is a component of other income (expense) in the Company’s consolidated statement of operations and comprehensive loss.

In connection with the issuance of the PHC Notes, the Company incurred $2.9 million in debt issuance costs and debt discounts. The associated debt issuance costs were recorded as a contra liability in the amount of $1.4 million and are deferred and amortized as additional interest expense over the term of the notes. There were no conversions of the PHC Notes prior to the exchange of the PHC Notes for the Exchange Warrant described above.

As described above, the Exchange Agreement with PHC was consummated on March 31, 2023, whereby PHC exchanged the PHC Notes in $35.0 million principal amount and all accrued and unpaid interest for the Exchange Warrant. On March 31, 2023, the Company was released from its obligation under the PHC Notes.

Upon execution of the Exchange Agreement, the exercise of the original conversion feature of the PHC Notes became remote. Accordingly, the Company remeasured the embedded derivative to its fair value of $0. The Company recognized a change in fair value of the embedded derivative of $44.2 million in the caption “Exchange related gain, net” that is a component of other income (expense) in the Company’s consolidated statement of operations and comprehensive loss.

The Company accounted for the Exchange as an extinguishment of the PHC Notes, and thus, it derecognized the PHC Notes in its consolidated balance sheets and recognized a loss of $25.4 million as the difference between the carrying value plus accrued interest of the PHC Notes of $23.2 million and the $48.6 million fair value of the Exchange Warrant as an extinguishment loss in the caption “Exchange related gain, net” that is a component of other income (expense) in the Company’s consolidated statement of operations and comprehensive loss. As a result of the Exchange, the Company recognized a total net gain on exchange of the PHC notes of $18.8 million representing the gain on change in the fair value of the PHC Notes conversion feature recognized as an embedded derivative and the loss on extinguishment of the PHC Notes in exchange for the Exchange Warrant.

2025 Notes

In July 2019, the Company issued $82.0 million in aggregate principal amount of senior convertible notes that will mature on January 15, 2025 (the “2025 Notes”), unless earlier repurchased or converted. The 2025 Notes are convertible, at the option of the holders, into shares of the Company’s common stock, at an initial conversion rate of 757.5758 shares per $1,000 principal amount of the 2025 Notes (equivalent to an initial conversion price of approximately $1.32 per share).

The 2025 Notes also contained an embedded conversion option requiring bifurcation as a separate derivative liability, along with the fundamental change make-whole provision and the cash settled fundamental make-whole shares provision. The derivative is adjusted to fair value at each reporting period, with the change in the fair value recorded to other income (expense) in the Company’s consolidated statement of operations and comprehensive loss. The fair value of the derivative at June 30, 2023 and December 31, 2022 was $1.8 million and $7.9 million, respectively.

On April 24, 2020, $24.0 million aggregate principal of the Company’s outstanding 2025 Notes held by Highbridge Capital Management, LLC (“Highbridge”) were exchanged for (i) $15.7 million of Second Lien Notes (the “Second Lien Notes”), (ii) 11,026,086 shares of common stock, (iii) warrants to purchase up to 4,500,000 shares of common stock at an exercise price of $0.66 per share, and (iv) $0.3 million in accrued and unpaid interest on the 2025 Notes being exchanged. This transaction modified the original 2025 Notes outstanding with Highbridge and resulted in

Table of Contents

$13.2 million of deferred issuance fees and debt discounts associated with the exchanged 2025 Notes being transferred as a discount to the Second Lien Notes.

In January 2021, there were conversions of $6.5 million of outstanding principal amount of the 2025 notes for 4,924,998 shares of common stock. Accordingly, $3.2 million of allocated deferred issuance costs and debt discounts were recognized as a loss on extinguishment of debt. There were no conversions of 2025 Notes during the six months ended June 30, 2023.

2023 Notes

In the first quarter of 2018, the Company issued $53.0 million in aggregate principal amount of senior convertible notes due February 1, 2023 (the “2023 Notes”). In July 2019, the Company used the net proceeds from the issuance of the 2025 Notes to repurchase $37.0 million aggregate principal amount of the outstanding 2023 Notes. Each $1,000 of principal of the 2023 Notes is initially convertible into 294.1176 shares of the Company’s common stock, which is equivalent to an initial conversion price of approximately $3.40 per share, subject to adjustment upon the occurrence of specified events. Holders may convert at any time prior to February 1, 2023. Holders who convert on or after the date that is six months after the last date of original issuance of the 2023 Notes but prior to February 1, 2021, may also be entitled to receive, under certain circumstances, an interest make-whole payment payable in shares of common stock. If specific corporate events occur prior to the maturity date, the Company will increase the conversion rate pursuant to the make-whole fundamental change provision for a holder who elects to convert their 2023 Notes in connection with such an event in certain circumstances. Additionally, if a fundamental change occurs prior to the maturity date, holders of the 2023 Notes may require the Company to repurchase all or a portion of their 2023 Notes for cash at a repurchase price equal to 100% of the principal amount plus any accrued and unpaid interest.

The Company bifurcated the embedded conversion option, along with the interest make-whole provision and make-whole fundamental change provision, and in January 2018 recorded the embedded features as a debt discount and derivative liability in the Company’s consolidated balance sheets at its initial fair value of $17.3 million. Additionally, the Company incurred transaction costs of $2.2 million. The debt discount and transaction costs are being amortized to interest expense over the term of the 2023 Notes at an effective interest rate of 9.30%. The derivative is adjusted to fair value at each reporting period, with the change in the fair value recorded to other income (expense) in the Company’s consolidated statement of operations and comprehensive loss. On January 31, 2023, the Company repaid the outstanding principal and accrued interest in full. The derivative was unexercised upon maturity and the fair value in the amount of $0.02 million was recognized as an extinguishment gain in the caption “Other income (expense)” in Company’s consolidated statement of operations and comprehensive loss.

2016 Employee Stock Purchase Plan

In February 2016, the Company adopted the 2016 Employee Stock Purchase Plan, (the “2016 ESPP”). The 2016 ESPP became effective on March 17, 2016. The maximum number of shares of common stock that may be issued under the 2016 ESPP was initially 800,000 shares and automatically increases on January 1 of each year, ending on and including January 1, 2026, by 1.0% of the total number of shares of common stock outstanding on December 31 of the preceding calendar year; provided, however, the Board of Directors may act prior to the first day of any calendar year to provide that there will be no January 1 increase in the share reserve for such calendar year or that the increase in the share reserve for such calendar year will be a lesser number of shares of common stock. As of June 30, 2023, there were 17,760,078 shares of common stock available for issuance under the 2016 ESPP. For the six months ended June 30, 2023, there were purchases of 86,816 shares of common stock pursuant to the 2016 ESPP.

The 2016 ESPP permits participants to purchase shares of the Company’s common stock through payroll deductions of up to 15% of their earnings. Unless otherwise determined by the administrator, the purchase price of the shares will be 85% of the lower of the fair market value of common stock on the first day of an offering or on the date of purchase. Participants may end their participation at any time and deductions not yet used in a purchase are refundable upon employment termination. The Company initiated its first 2016 ESPP offering period on August 1, 2019 and new offering periods occur every six months thereafter, each consisting of two purchase periods of six months in duration ending on or about January 31^st and July 31^st of each year. A participant may only be in one offering at a time. On February 1, 2020, there were 566,573 shares purchased in connection with the offering period. The 2016 ESPP contains an offering reset provision whereby if the fair market value of a share on offering date of an ongoing offering is less than or equal to the fair market value of a share on a new offering date, the ongoing offering will terminate immediately after the purchase date and rolls over to the new offering.

The 2016 ESPP is considered compensatory for financial reporting purposes.

2025 Notes Exchange Agreements

Table of Contents

5.25% Convertible Senior Notes due 2025 (the “2025 Notes”). Under the terms of the Exchange Agreements, the Noteholders have agreed to exchange with the Company (the “Exchanges”) up to $30.8 million in aggregate principal amount of the Company’s outstanding 2025 Notes (the “Exchanged Notes”) for a combination of $7.5 million of cash and newly issued shares of common stock (the “Exchange Shares”). The Exchanged Notes are presently convertible into an aggregate of approximately 23.3 million shares. The number of Exchange Shares to be issued to the Noteholders will be determined based upon the volume-weighted average price per share of the Common Stock during a 15-day averaging period commencing on August 11, 2023. The maximum number of Exchange Shares that may be issued is 10% of the Company’s common stock outstanding as of August 10, 2023 (the “Exchange Share Cap”). If the average trading price over the averaging period would otherwise result in the number of shares to be issued exceeding the Exchange Share Cap, the amount of the Exchanged Notes will be proportionally reduced. The Exchanges are subject to customary closing conditions and are expected to close on or about September 5, 2023.

At-the-Market Offering Program

As previously disclosed, in November 2021, the Company entered into an Open Market Sale Agreement with Jefferies, pursuant to which the Company could offer and sell, from time to time, at its sole discretion, shares of its common stock having an aggregate offering price of up to $150.0 million through Jefferies as its sales agent in an “at the market” offering. On August 7, 2023, the Company and Jefferies mutually agreed to terminate the Open Market Sale Agreement, effective as of August 7, 2023. Prior to termination, the Company had sold an aggregate of 25,105,562 shares under the Open Market Sale Agreement, resulting in gross proceeds of approximately $43.4 million, before deducting commissions and offering expenses. At the time of termination, approximately $106.6 million remained available for issuance pursuant to the Open Market Sale Agreement.

On August 10, 2023, the Company entered into the Equity Distribution Agreement with Goldman Sachs & Co. LLC, which will enable the Company to issue and sell shares of Common stock in one or more negotiated transactions or transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act, for a maximum aggregate offering amount of up to $106.6 million (the “ATM Program”).

The shares will be offered and sold pursuant to a shelf registration statement on Form S-3 (the “Registration Statement”), filed with the Securities and Exchange Commission (the “Commission”) on August 10, 2023. The Registration Statement has not yet been declared effective by the Commission and no sales may be made until such time as the Registration Statement is declared effective. The Registration Statement, once effective, will provide for the issuance of common stock from time to time, in one or more transactions, in the aggregate offering amount of $106.6 million, inclusive of the $106.6 million pursuant to the ATM Program.

Overview

We are a medical technology company focused on the development and manufacturing of glucose monitoring products designed to transform lives in the global diabetes community with differentiated, long-term implantable glucose management technology. Our implantable CGM (“Eversense”), including 90-day Eversense, Eversense XL and Eversense E3 CGM system versions are designed to continually and accurately measure glucose levels in people with diabetes via an under-the-skin sensor, a removable and rechargeable smart transmitter, and a convenient app for real-time diabetes monitoring and management for a period of up to six months in the case of Eversense XL and Eversense E3, as compared to seven to 14 days for non-implantable CGM systems. We affixed the CE mark to the original 90-day Eversense CGM system in June 2016, which marked the first certification for the product to be sold within the European Economic Area (being the European Union plus Norway, Iceland, and Liechtenstein) (“EEA”). Subsequently, we affixed the CE mark to the extended life Eversense XL CGM system in September 2017 to be sold in select markets in Europe and the Middle East. In June 2022, we affixed the CE mark to the extended life Eversense E3 CGM system and Ascensia began commercialization in select markets in Europe during the third quarter of 2022. In June 2018, the FDA, approved the 90-day Eversense CGM system for distribution throughout the United States. In June 2019, we received FDA approval for the non-adjunctive indication (dosing claim) for the 90-day Eversense system. With this approval and the availability of a new app in December 2019, the Eversense system can now be used as a therapeutic CGM in the United States to replace fingerstick blood glucose measurement to make treatment decisions, including insulin dosing. In February 2022, the 180-day extended life Eversense E3 CGM system was approved by the FDA and Ascensia began commercializing Eversense E3 in the United States in the second quarter of 2022.

Our net revenues are derived from sales of the Eversense system which is sold in two separate kits: the disposable Eversense Sensor Pack which includes the sensor, insertion tool, and adhesive patches, and the durable Eversense Smart Transmitter Pack which includes the transmitter and charger.

We sell directly to our network of distributors and strategic fulfillment partners, who provide the Eversense system to healthcare providers and patients through a prescribed request and invoice insurance payors for reimbursement. Sales of the Eversense system are widely dependent on the ability of patients to obtain coverage and

adequate reimbursement from third-party payors or government agencies. We leverage and target regions where we have coverage decisions for patient device use and provider insertion and removal procedure payment. We have reached approximately 300 million covered lives in the United States through positive insurance payor coverage decisions. In June 2023, we received positive payor coverage decision from UnitedHealthcare, the largest healthcare insurance company in the United States that effective July 1, 2023, Eversense E3 CGM system would be covered. On August 3, 2020, the Center for Medicare and Medicaid Services (“CMS”) released its Calendar Year 2021 Medicare Physician Fee Schedule Proposed Rule that announces proposed policy changes for Medicare payments, including the proposed establishment of national payment amounts for the three CPT© Category III codes describing the insertion (CPT 0446T), removal (0447T), and removal and insertion (0048T) of an implantable interstitial glucose sensor, which describes our Eversense CGM systems, as a medical benefit, rather than as part of the Durable Medical Equipment channel that includes other CGMs. In December 2021, CMS released its Calendar Year 2022 Medicare Physician Fee Schedule that updated global payments for the device cost and procedure fees. In July 2022, CMS provided temporary G-codes to enable immediate access to Eversense E3 for all eligible Medicare beneficiaries. In November 2022, CMS released its Calendar Year 2023 Medicare Physician Fee Schedule Proposed Rule that updates the payment amounts for the three CPT© Category III codes to account for the longer 6-month sensor.

In February 2020, we announced that the FDA approved a subgroup of PROMISE trial participants to continue for a total of 365 days to gather feasibility data on the safety and accuracy of a 365-day sensor. This sub-set of 30 participants was left undisturbed for 365 days with the goal of measuring accuracy and longevity over the full 365 days. Information gathered from this sub-set and additional development efforts provided us the confidence to start the Pivotal study for the Eversense 365-day System. The ENHANCE pivotal study for the Eversense 365-day system completed enrollment in the third quarter of 2022 and we expect to have data in the second half of 2023.

We are in the early commercialization stages of the Eversense brand and are focused on driving awareness of our CGM system amongst intensively managed patients and their healthcare providers. In both the United States and our overseas markets, we have entered into strategic partnerships and distribution agreements that allow third party collaborators with direct sales forces and established distribution systems to market and promote Senseonics CGM systems, including 90-day Eversense, Eversense XL, Eversense E3 and future generation products.

United States Development and Commercialization of Eversense

In 2016, we completed our PRECISE II pivotal clinical trial in the United States. This trial, which was fully enrolled with 90 subjects, was conducted at eight sites in the United States. In the trial, we measured the accuracy of Eversense measurements through 90 days after insertion. We also assessed safety through 90 days after insertion or through sensor removal. In the trial, we observed a mean absolute relative difference (“MARD”), of 8.5% utilizing two calibration points for Eversense across the 40-400 mg/dL range when compared to YSI blood reference values during the 90-day continuous wear period. Based on the data from this trial, in October 2016 we submitted a pre-market approval (“PMA”) application to the FDA to market Eversense in the United States for 90-day use. On June 21, 2018, we received PMA approval from the FDA for the Eversense system. In July 2018, we began distributing the 90-day Eversense system directly in the United States through our own direct sales and marketing organization. We have received Category III CPT codes for the insertion and removal of the Eversense sensor.

In December 2018, we initiated the PROMISE pivotal clinical trial to evaluate the safety and accuracy of Eversense for a period of up to six months in the United States and in September 30, 2019, we completed enrollment of the PROMISE trial. In the trial, we observed performance matching that of the then current Eversense 90-day product available in the United States, with a MARD of 8.5%. This result was achieved with reduced calibration, down to one per day, while also doubling the sensor life to six months. Following the results of the PROMISE trial, on September 30, 2020, a PMA supplement application to extend the wearable life of the Eversense CGM System to six months was submitted to the FDA. In February 2022, the extended life Eversense E3 CGM system was approved by the FDA.

In June 2019, we received FDA approval for the non-adjunctive indication (dosing claim) for the Eversense system and launched with an updated app in December 2019. With this approval, the Eversense system can be used as a therapeutic CGM to replace fingerstick blood glucose measurement for treatment decisions, including insulin dosing.

On February 26, 2020, we announced that the FDA approved a subgroup of PROMISE trial participants to continue for a total of 365 days to gather feasibility data on the safety and accuracy of a 365-day sensor. This sub-set of 30 participants were left undisturbed for 365 days with the goal of measuring accuracy and longevity over the full 365 days. Information gathered from this sub-set and additional development efforts provided us the confidence to start the Pivotal study for the Eversense 365 System.

In April 2020, we announced that we received an extension to our CE Certificate of Conformity in the EEA such that the Eversense XL is no longer contraindicated for MRI, which means the sensor does not need to be removed from under the skin during MRI scanning. We had previously obtained this indication for Eversense in the United States in 2019. This MRI approval is a first for the CGM category, as all other sensors are required to be removed during an MRI scan.

On August 9, 2020, we entered into a collaboration and commercialization agreement with Ascensia (the “Commercialization Agreement”) pursuant to which we granted Ascensia the exclusive right to distribute our 90-day Eversense CGM system and our 180-day Eversense E3 CGM system worldwide, with the following initial exceptions: (i) until January 31, 2021, the territory did not include countries covered by our then existing distribution agreement with Roche Diagnostics International AG and Roche Diabetes Care GmbH (together “Roche”), which included Europe, Middle East and Asia, excluding Scandinavia and Israel, and 17 additional countries, including Brazil, Russia, India and China, as well as select markets in the Asia Pacific and Latin American regions; (ii) until September 13, 2021, the territory did not include countries covered by our then current distribution agreement with Rubin Medical, which included Sweden, Norway and Denmark; and (iii) until May 31, 2022, the territory did not include Israel. Pursuant to the Commercialization Agreement, in the United States, Ascensia began providing sales support for the 90-day Eversense product on October 1, 2020 and Ascensia ramped up sales activities and assumed commercial responsibilities for the 90-day Eversense product during the second quarter of 2021.

In February 2022, we received approval from the FDA for the Eversense E3 CGM System. The approval for our third-generation sensor, with proprietary sacrificial boronic acid (“SBA”) technology doubles the sensor life to six months with MARD of 8.5%. Ascensia began commercializing Eversense E3 in the United States during the second quarter of 2022.

The ENHANCE clinical study was initiated as a pivotal study with the purpose of gathering additional clinical data to support an integrated continuous glucose monitoring (iCGM) submission for the Eversense E3 system using the SBA technology. In March 2022, we extended the ongoing ENHANCE clinical study to evaluate the safety and accuracy of the Eversense 365 System for a period of up to one year in the United States. In September 2022, we completed enrollment of the ENHANCE study. In November 2022, we submitted and in the first quarter of 2023 we received approval of an IDE for the enrollment of a pediatric cohort in the ENHANCE study. We began to enroll pediatric patients during the second quarter of 2023.

European Commercialization of Eversense

In September 2017, we affixed the CE mark for Eversense XL which indicates that the product may be sold freely in any part of the European Economic Area (“EEA”). The Eversense XL is indicated for a sensor life of up to 180 days. Eversense XL began commercialization in Europe in the fourth quarter of 2017. All such commercialization and marketing activities remain subject to applicable government approvals.

In May 2016, we entered into a distribution agreement with Roche. Pursuant to the agreement, as amended, we had granted Roche the exclusive right to market, sell and distribute Eversense in the EMEA, excluding Scandinavia and Israel. In addition, Roche had exclusive distribution rights in 17 additional countries, including Brazil, Russia, India and China, as well as select markets in the Asia Pacific and Latin American regions. Roche was obligated to purchase from us specified minimum volumes of Eversense XL CGM components at pre-determined prices. On November 30, 2020, we entered into a final amendment and settlement agreement with Roche to facilitate the transition of distribution to Ascensia as sales concluded on January 31, 2021, including final purchases, and transition support activities. The distribution rights under the agreement expired January 31, 2021.

In June 2022, we affixed the CE mark to the extended life Eversense E3 CGM system, and Ascensia began commercialization in European markets during the second half of 2022.

Financial Overview

Revenue

We generate product revenue from sales of the Eversense system and related components and supplies to Ascensia, through the Commercialization Agreement, third-party distributors in the European Union and to strategic fulfillment partners in the United States (collectively “Customers”), who then resell the products to health care providers and patients. We are generally paid for our sales directly to the Customers, regardless of whether or not the Customers resell the products to health care providers and patients.

Revenue from product sales is recognized at a point in time when the Customers obtain control of our product based upon the delivery terms as defined in the contract at an amount that reflects the consideration which we expect to receive in exchange for the product. Contracts with our distributors contain performance obligations, mostly for the supply of goods, and is typically satisfied upon transfer of control of the product. Additionally, a portion of revenue is recognized through our consignment program whereas small quantities of inventory are maintained securely at various health care provider locations within the United States. Under this model, the Company does not recognize revenue upon shipment of product. Rather, revenue is recognized when the product is consumed by a patient.

Customer contracts do not include the right to return unless there is a product issue, in which case we may provide replacement product. Product conformity guarantees do not create additional performance obligations and are accounted for as warranty obligations in accordance with guarantee and loss contingency accounting guidance.

Our contracts may contain some form of variable consideration such as prompt-pay discounts, tier-volume price discounts and for the Ascensia commercial agreement, revenue share. Variable consideration, such as discounts and prompt-pay incentives, are treated as a reduction in revenue and variable considerations, such as revenue share, is treated as an addition in revenue when the product sale is recognized. The amount of variable consideration that is included in the transaction price may be constrained and is included in revenue only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period, when the uncertainty associated with the variable consideration is subsequently resolved. Estimating variable consideration and the related constraint requires the use of management judgment. Depending on the variable consideration, we develop estimates for the expected value based on the terms of the agreements, historical data, geographic mix, reimbursement rates, and market conditions.

Total revenue

Our total revenue increased to $4.1 million for the three months ended June 30, 2023, compared to $3.7 million for the three months ended June 30, 2022, an increase of $0.4 million. This increase was primarily due to the launch of Eversense E3 outside of the United States in the third quarter of 2022 driving higher revenue in the current year.

Cost of sales and gross profit

Our cost of sales increased to $3.7 million for the three months ended June 30, 2023, compared to $2.9 million for the three months ended June 30, 2022. Our gross profit decreased to $0.4 million for the three months ended June 30, 2023, compared to $0.8 million for the three months ended June 30, 2022. Gross profit as a percentage of revenue, or gross margin, was 10.1% and 22.2% for the three months ended June 30, 2023 and June 30, 2022, respectively. The reduction in gross margin was primarily driven by an increase in the revenue share percentage due to Ascensia, sales channel mix and increased manufacturing and logistics costs.

Research and development expenses

Research and development expenses were $12.8 million for the three months ended June 30, 2023, compared to $9.3 million for the three months ended June 30, 2022, an increase of $3.5 million. The increase was primarily due to investments in next generation technologies including a $3.1 million increase in clinical studies activities and a $0.4 million increase in research and development support services.

Liquidity and Capital Resources

Sources of Liquidity

From its founding in 1996 until 2010, the Company has devoted substantially all of its resources to researching various sensor technologies and platforms. Beginning in 2010, the Company narrowed its focus to developing and refining a commercially viable glucose monitoring system. The Company has incurred substantial losses and cumulative negative cash flows from operations since its inception in October 1996 and expects to incur additional losses in the near future. We incurred total gross profit of $2.7 million, ($0.8) million, and ($17.4) million for the years ended December 31, 2022, 2021 and 2020, respectively. For the period ending June 30, 2023, the Company had gross profit of $0.4 million and an accumulated deficit of $828.0 million. To date, the Company has funded its operations principally through the issuance of preferred stock, common stock, warrants, convertible notes, and debt. As of June 30, 2023, the Company had cash, cash equivalents and marketable securities of $125.1 million.

On August 10, 2023 the Company entered into separate, privately negotiated exchange agreements (the “Exchange Agreements”) with a limited number of holders (the “Noteholders”) of the Company’s currently outstanding 5.25% Convertible Senior Notes due 2025 (the “2025 Notes”). Under the terms of the Exchange Agreements, the Noteholders have agreed to exchange with the Company (the “Exchanges”) up to $30.8 million in aggregate principal amount of the Company’s outstanding 2025 Notes (the “Exchanged Notes”) for a combination of $7.5 million of cash and newly issued shares of common stock (the “Exchange Shares”). The Exchanged Notes are presently convertible into an aggregate of approximately 23.3 million shares. The number of Exchange Shares to be issued to the Noteholders will be determined based upon the volume-weighted average price per share of the Common Stock during a 15-day averaging period commencing on August 11, 2023. The maximum number of Exchange Shares that may be issued is 49,303,648 shares, representing 10% of the Company’s common stock outstanding as of August 10, 2023 (the “Exchange Share Cap”). If the average trading price over the averaging period would otherwise result in the number of shares to be issued exceeding the Exchange Share Cap, the amount of the Exchanged Notes will be proportionally reduced. The Exchanges are subject to customary closing conditions and are expected to close on or about September 5, 2023.

Table of Contents

Assuming the successful consummation of the Exchanges, upon completion of the Exchanges, we anticipate that the restrictive covenants of the 2025 Notes will no longer be applicable, including limitations on indebtedness, and that approximately $19.2 million aggregate principal amount of the 2025 Notes will remain outstanding.

In August 2023, the Company entered into an Equity Distribution Agreement, (the “Equity Distribution Agreement”) with Goldman Sachs & Co. LLC (“GS”), under which the Company could offer and sell, from time to time, at its sole discretion, shares of its common stock having an aggregate offering price of up to $106.6 million through GS as its sales agent in an “at the market” offering. GS will receive a commission up to 3.0% of the gross proceeds of any common stock sold through GS under the Equity Distribution Agreement. The shares will be offered and sold pursuant to a shelf registration statement on Form S-3 (the “Registration Statement”), filed with the Securities and Exchange Commission (the “Commission”) on August 10, 2023. The Registration Statement has not yet been declared effective by the Commission and no sales may be made until such time as the Registration Statement is declared effective. The Registration Statement, once effective, will provide for the issuance of common stock from time to time, in one or more transactions, in the aggregate offering amount of $106.6 million, inclusive of the $106.6 million pursuant to the ATM Program.

In November 2021, we entered into the 2021 Sales Agreement with Jefferies, under which we could offer and sell, from time to time, at our sole discretion, shares of our common stock having an aggregate offering price of up to $150.0 million through Jefferies as our sales agent in an “at the market” offering. Jefferies will receive a commission up to 3.0% of the gross proceeds of any common stock sold through Jefferies under the 2021 Sales Agreement. During the six months ended June 30, 2023, the Company received $7.4 million in net proceeds from the sale of 9,944,663 shares of its common stock under the 2021 Sales Agreement. For the six months ended June 30, 2022, Company received $8.0 million in net proceeds from the sale of 3,077,493 shares of its common stock under the 2021 Sales Agreement. On August 7, 2023, the Company and Jefferies mutually agreed to terminate the Open Market Sale Agreement, effective as of August 7, 2023. At the time of termination, approximately $106.6 million remained available for issuance pursuant to the 2021 Sales Agreement

On November 9, 2020, the Company entered into the Equity Line Agreement with Energy Capital which provided that, upon the terms and subject to the conditions and limitations set forth therein, Energy Capital was committed to purchase up to an aggregate of $12.0 million of shares of the Company’s newly designated Series B Preferred Stock at the Company’s request from time to time during the 24-month term of the Equity Line Agreement. Under the Equity Line Agreement, beginning January 21, 2021, subject to the satisfaction of certain conditions, including that the Company have less than $8.0 million of cash, cash equivalents and other available credit (aside from availability under the Equity Line Agreement), the Company had the right, at its sole discretion, to present Energy Capital with a Regular Purchase Notice directing Energy Capital (as principal) to purchase shares of Series B Preferred Stock at a price of $1,000 per share (not to exceed $4.0 million worth of shares) once per month, up to an aggregate of $12.0 million of the Company’s Series B Preferred Stock at a per share price (the “Purchase Price”) equal to $1,000 per share of Series B Preferred Stock, with each share of Series B Preferred Stock initially convertible into common stock, beginning six months after the date of its issuance, at a conversion price of $0.3951 per share, subject to customary anti-dilution adjustments, including in the event of any stock split. The Equity Line Agreement provided that the Company was not permitted to affect any Regular Purchase Notice under the Equity Line Agreement on any date where the closing price of the Company’s common stock on the NYSE American is less than $0.25 without the approval of Energy Capital. In addition, beginning on January 1, 2022, since there had been no sales of the Series B Preferred Stock pursuant to the Equity Line Agreement, Energy Capital had the right, at its sole discretion, by its delivery to the Company of a Regular Purchase Notice, to purchase up to the $12.0 million of Series B Preferred Stock under the Equity Line Agreement at the Purchase Price. On November 7, 2022, Energy Capital exercised in full its right to purchase $12.0 million of Series B Preferred Stock. The excess of the Purchase Price and the fair value of the Energy Capital option in the total amount of $37.6 million was recorded in additional-paid-in-capital.

On August 9, 2020, the Company entered into a financing agreement with PHC, pursuant to which the Company issued $35.0 million in aggregate principal amount of Senior Secured Convertible Notes due on October 31, 2024 (the “PHC Notes”), to PHC. The Company also issued 2,941,176 shares of common stock to PHC as a financing fee. The Company also has the option to sell and issue PHC up to $15.0 million of convertible preferred stock on or before December 31, 2022, contingent upon obtaining FDA approval for the 180-day Eversense product for marketing in

the United States before such date. The Company successfully obtained FDA approval in February 2022 and the option was not exercised.

On March 13, 2023, the Company entered into an Exchange Agreement with PHC, pursuant to which PHC agreed to exchange its $35.0 million aggregate principal amount of the PHC Notes, including all accrued and unpaid interest thereon, for the Exchange Warrant to purchase up to 68,525,311 Exchange Warrant Shares. The Exchange Warrant is a “pre-funded” warrant with a nominal exercise price of $0.001 per Exchange Warrant Share. The number of Exchange Warrant Shares represents the number of shares of common stock previously issuable upon conversion of the PHC Notes, in accordance with the original terms of the notes, including a number of shares in respect of accrued and unpaid interest through the closing date, plus additional shares with a value of $675,000 reflecting a portion of the future interest payments forgone by PHC. On March 31, 2023, the Exchange was consummated, and the Company issued the Exchange Warrant to PHC in consideration for the cancellation of the PHC Notes.

On March 13, 2023, the Company entered into a Securities Purchase Agreement with PHC, pursuant to which the Company issued and sold to PHC in a private placement a Purchase Warrant to purchase an aggregate of 15,425,750 Purchase Warrant Shares. The purchase price of the Purchase Warrant was approximately $0.97 per Purchase Warrant Share, representing the undiscounted, trailing 10-day volume weighted average price of the Company’s common stock through March 10, 2023. The Purchase Warrant is a “pre-funded” warrant with a nominal exercise price of $0.001 per Purchase Warrant Share. The issuance of the Purchase Warrants enabled PHC to maintain, as of the closing of the transaction, a 15% beneficial ownership for purposes of the Investor Rights Agreement, dated August 9, 2020, between the Company and PHC.

On the Private Placement Closing Date, the Company received aggregate gross proceeds of $15.0 million, before deducting private placement expenses payable by the Company.

Funding Requirements and Outlook

Our ability to grow revenues and achieve profitability depends on the successful commercialization and adoption of our Eversense CGM systems by diabetes patients and healthcare providers, along with future product development, regulatory approvals, and post-approval requirements. These activities, including our ongoing focus to grow covered lives through positive insurance payor policy decisions and continued development of Eversense 365-day product, will require significant uses of working capital through 2023 and beyond.

We believe that our existing agreements, including the transactions with PHC, evidence the mutual commitment of PHC and the Company to support the commercialization of Eversense and specifically for the Company, provide the financial resources for manufacturing of Eversense and continued product development. We expect that existing cash, cash equivalents and cash flows from our future operations will be sufficient to meet the Company’s current operating plans into 2025. As part of our liquidity strategy, we will continue to monitor our capital structure and market conditions going forward and we may access the debt and equity or equity linked markets for additional funding if the opportunity arises to enhance our capital structure, for changes to our operating plans, for financing strategic initiatives and to provide financial flexibility.

Under SEC rules and regulations, because we are considered to be a “smaller reporting company”, we are not required to provide the information required by this item in this Quarterly Report on Form 10-Q.

ITEM 4: Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the assistance of our chief executive officer, who is our principal executive officer, and our chief financial officer, who is our principal financial officer, has reviewed and evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of June 30, 2023.

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving such control objectives.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended June 30, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II: OTHER INFORMATION

ITEM 1: Legal Proceedings

From time to time, we are subject to litigation and claims arising in the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business. Legal proceedings, including litigation, government investigations and enforcement actions could result in material costs, occupy significant management resources and entail civil and criminal penalties.

In February 2021, the Company received notice and accepted service of a civil complaint that had been filed in the Western District of Texas and styled Carew ex rel. United States v. Senseonics, Inc., No. SA20CA0657DAE. The complaint was filed by a relator under seal in May 2020 pursuant to the qui tam provisions in the federal False Claims Act. Prior to the unsealing of the complaint, the government declined to intervene in the case. The case, therefore, is being pursued only by the relator and his counsel. The complaint alleges the Company’s marketing practices with physicians for its product, Eversense CGM system, violated the False Claims Act, 31 U.S.C. § 3729 and the Texas Medicaid Fraud Prevention Law, Tex. Hum Res. Code § 36.002. The court granted the Company’s motion to dismiss the complaint on March 31, 2022 but permitted the plaintiff to file an amended complaint. The court dismissed the amended complaint and entered judgment in favor of Senseonics Holdings, Inc. on March 30, 2023. The relator filed a notice of appeal to the United States Court of Appeals for the Fifth Circuit on April 28, 2023 and the parties are briefing the appeal.

ITEM 1A: Risk Factors

Our business is subject to risks and events that, if they occur, could adversely affect our financial condition and results of operations and the trading price of our securities. Except as set forth below, our risk factors as of the date of this Quarterly Report on Form 10-Q have not changed materially from those described in “Part I, Item 1A. Risk Factors” of our Annual Report on Form 10-K.

Our recent exchange agreements with certain holders of our 2025 Notes will result in additional dilution and could cause our stock price to decline.

On August 10, 2023, we entered into a series of exchange agreements with certain holders of our 2025 Notes, pursuant to which these noteholders have agreed to exchange an aggregate principal amount of up to $30.8 million of 2025 Notes for a combination of cash and newly issued shares of common stock. The number of shares we issue in connection with these exchanges will be based on the average price of our common stock over the ensuing 15 trading day period, subject to a total limit of 10% of our outstanding shares of common stock outstanding as of August 10, 2023. The number of shares that we issue in connection with these exchanges will exceed the number of shares currently underlying the 2025 Notes being exchanged, resulting in incremental dilution to our common stockholders. Additionally, the shares that we issue to these noteholders will generally be eligible for immediate resale in the open market without restriction, which could potentially increase the number of shares sold over the near term and could cause our stock price to decline. Additionally, if as result of declines in our stock price, the total amount of 2025 Notes repurchased in these exchanges is less than we anticipate, we may not realize the full benefits that we anticipate from these transactions, including the overall level of debt reduction and the elimination of restrictive covenants under the 2025 Notes.

ITEM 5: Other Information

2025 Notes Exchange Agreements

On August 10, 2023 the Company entered into separate, privately negotiated exchange agreements (the “Exchange Agreements”) with a limited number of holders (the “Noteholders”) of the Company’s currently outstanding 5.25% Convertible Senior Notes due 2025 (the “2025 Notes”). Under the terms of the Exchange Agreements, the Noteholders have agreed to exchange with the Company (the “Exchanges”) up to $30.8 million in aggregate principal amount of the Company’s outstanding 2025 Notes (the “Exchanged Notes”) for a combination of $7.5 million of cash and newly issued shares of common stock (the “Exchange Shares”). The Exchanged Notes are presently convertible into an aggregate of approximately 23.3 million shares. The number of Exchange Shares to be issued to the Noteholders will be determined based upon the volume-weighted average price per share of the Common Stock during a 15-day averaging period commencing on August 11, 2023. The maximum number of Exchange Shares that may be issued is 10% of the Company’s common stock outstanding as of August 10, 2023 (the “Exchange Share Cap”). If the average trading price over the averaging period would otherwise result in the number of shares to be issued exceeding the Exchange Share Cap, the amount of the Exchanged Notes will be proportionally reduced. The Exchanges are subject to customary closing conditions and are expected to close on or about September 5, 2023.

The foregoing description of the Exchange Agreements and the Exchanges contemplated thereby is not complete and is subject to, and qualified in its entirety by reference to, the form of Exchange Agreement, a copy of which is filed with this Quarterly Report as Exhibit 10.1 and the terms of which are incorporated herein by reference.

The Exchange Shares were offered, and will be sold, pursuant to the exemption provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”) as a transaction by an issuer not involving a public offering.

At-the-Market Offering Program

On August 10, 2023, the Company entered into an equity distribution agreement (the “Equity Distribution Agreement”) with Goldman Sachs & Co. LLC, which will enable the Company to issue and sell shares of Common stock in one or more negotiated transactions or transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act, for a maximum aggregate offering amount of up to $106.6 million (the “ATM Program”).

The undersigned investor (the “Investor”), for itself and on behalf of the beneficial owners listed on Exhibit A hereto (“Accounts”) for whom the Investor holds contractual and investment authority (each, including the Investor if it is a party exchanging Notes (as defined below), an “Exchanging Investor”), hereby agrees to exchange, with Senseonics Holdings, Inc., a Delaware corporation (the “Company”), certain 5.25% Convertible Senior Notes due 2025, CUSIP 81727U AC9 (the “Notes”) for the Exchange Consideration (as defined below) pursuant to this exchange agreement (the “Agreement”). The Investor understands that the exchange (the “Exchange”) is being made without registration of the offer or sale of the Shares (as defined below) under the Securities Act of 1933, as amended (the “Securities Act”), or any securities laws of any state of the United States or of any other jurisdiction in a private placement pursuant to the exemption from registration provided by Section 4(a)(2) of the Securities Act and that each Exchanging Investor participating in the Exchange is required to be an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act that is also a “qualified institutional buyer” within the meaning of Rule 144A under the Securities Act and an “Institutional Account” as defined in FINRA Rule 4512(c). Capitalized terms used but not defined in this Agreement have the respective meanings set forth in the Indenture, dated as of July 25, 2019 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee (the “Trustee”).

1.Exchange. On the basis of the representations, warranties and agreements herein contained and subject to the terms and conditions herein set forth, the Investor hereby agrees to exchange for itself and on behalf of the Exchanging Investors, an aggregate principal amount of the Notes set forth on Exhibit A hereto (the “Exchanged Notes”) for:

(a)An amount of cash, per $1,000 principal amount of such Exchanged Notes, equal to $243.51 (the “Cash Payment”);

(b)A number of shares (the “Shares”) of the Company’s common stock, $0.001 par value per share (the “Common Stock”), per $1,000 principal amount of such Exchanged Notes equal to the Conversion Ratio (the “Initial Shares”, and together with the Cash Payment, the “Initial Exchange Consideration”); plus

(c)An additional number of Shares per $1,000 principal amount of such Exchanged Notes equal to the difference of (x) the quotient of (i) the Final Purchase Price less the Cash Payment divided by (ii) the average of the Daily VWAPs (as defined below) over the Reference Period (as defined below) (such average, the “Reference Price”) less (y) the Conversion Ratio (the “Final Settlement Shares” and together with the Initial Exchange Consideration, the “Exchange Consideration”);

in the case of clauses (b) and (c) above, as adjusted in good faith by the Company for any stock dividend, stock split, stock combination, reclassification or similar transaction occurring on or after the date hereof and prior to the applicable Settlement Date; provided that the number of Shares to be exchanged for the Exchanged Notes shall be rounded down to the nearest whole share for each Exchanging Investor.

Notwithstanding the foregoing, in no event shall the number of Shares issuable under this Agreement and in exchange for other Notes pursuant to any other exchange agreement entered into on or about the date of this Agreement (the “Other Exchange Agreements”) between the Company and holders of such other Notes with respect to the exchange of Notes for Common Stock exceed 10.0% of the Company’s issued and outstanding Common Stock on the date hereof (the “Threshold”). If such aggregate amount of shares of Common Stock were to exceed the Threshold, the principal amount of Final Exchanged Notes (as defined below) exchanged by each Exchanging Investor under this Agreement and the “Exchanging Investors” under the Other Exchange Agreements shall be reduced on a pro rata basis (but not below zero) based on the principal amount of Notes exchanged by each such Exchanging Investor under this Agreement and each such “Exchanging Investor” under the Other Exchange Agreements such that such aggregate amount of Shares would approximately equal the Threshold (and for the avoidance of doubt, no Shares in excess of the Threshold or other additional consideration shall be deliverable by the Company in respect of the Initial Exchanged Notes).

“Business Day” means any day other than a Saturday, a Sunday or a day on which the Federal Reserve Bank of New York is authorized or required by law or executive order to close or be closed.

The “Daily VWAP” shall be determined without regard to after-hours trading or any other trading outside of the regular trading session trading hours.

“Delta Percentage” means 60%.

“Final Exchanged Notes” means an aggregate principal amount of Exchanged Notes identified as “Final Exchanged Notes” on Exhibit A hereto.

“Final Purchase Price” means the sum of (A) the Initial Purchase Price and (B) the product of (x) the Reference Price less the Initial Reference Price (y) the Conversion Ratio and (z) the Delta Percentage.

“Market Disruption Event” means (a) a failure by the primary U.S. national or regional securities exchange or market on which the Common Stock is listed or admitted for trading to open for trading during its regular trading session or (b) the occurrence or existence prior to 1:00 p.m., New York City time, on any Scheduled Trading Day for the Common Stock for more than one half-hour period in the aggregate during regular trading hours of any suspension or limitation imposed on trading (by reason of movements in price exceeding limits permitted by the relevant stock exchange or otherwise) in the Common Stock or in any options contracts or futures contracts relating to the Common Stock.

“Reference Period” means the period of 15 consecutive Trading Days commencing on the first Trading Day following the date hereof.

“Trading Day” means a day on which (a) there is no Market Disruption Event and (b) trading in the Common Stock generally occurs on The NYSE American or, if the Common Stock is not then listed on The NYSE American, on the principal other U.S. national or regional securities exchange on which the Common Stock is then listed or, if the Common Stock is not then listed on a U.S. national or regional securities exchange, on the principal other market on which the Common Stock is then listed or admitted for trading, except that if the Common Stock is not so listed or admitted for trading, “Trading Day” means a Business Day.

“Scheduled Trading Day” means a day that is scheduled to be a Trading Day on the principal U.S. national or regional securities exchange or market on which the Common Stock is listed or admitted for trading.

The Investor agrees that it and any Exchanging Investor shall not deliver a Notice of Conversion with respect to any Exchanged Notes and the Investor and each Exchanging Investor shall hold the Exchanged Notes until the applicable Closing (as defined below). In consideration for the performance of their obligations hereunder (including as described in the immediately preceding sentence), the Company agrees to deliver the Initial Exchange Consideration on the Initial Closing Date (as defined below) and the Final Settlement Shares on the Final Closing Date to each Exchanging Investor in exchange for its Exchanged Notes.

The Exchange shall occur in accordance with the procedures set forth in Exhibit B.2 hereto (the “Exchange Procedures”); provided that each of the Company and the Investor acknowledges that the delivery of the Shares to any Exchanging Investor may be delayed due to procedures and mechanics within the system of the transfer agent, The Depositary Trust Company (“DTC”) or The NYSE American (including the procedures and mechanics regarding the listing of the Shares on The NYSE American) or other events beyond the Company’s control and that such a delay will not be a default under this Agreement so long as (i) the Company is using its reasonable best efforts to effect such delivery, or (ii) such delay arises due to a failure by Investor to deliver settlement instructions in accordance with Section 3(q); provided, further, that no delivery of Shares will be made until the Exchanged Notes have been

properly submitted for exchange in accordance with the Exchange Procedures and no accrued interest will be payable by reason of any delay in making such delivery.

The initial settlement of the Exchange (the “Initial Closing”) shall take place remotely via the exchange of documents and signatures at 10:00 a.m., New York City time, on August 14, 2023 (subject to the provisos to the immediately preceding paragraph, the “Initial Closing Date”), or at such other time and place as the Company and the Investor may mutually agree. The final settlement of the Exchange (the “Final Closing” and together with the Initial Closing, each a “Closing”) shall take place remotely on the second Trading Day immediately following the last Trading Day of the Reference Period (subject to the provisos to the immediately preceding paragraph, the “Final Closing Date,” together with the Initial Closing, each a “Closing Date”), or at such other time and place as the Company and the Investor may mutually agree.

On the Initial Closing Date, subject to satisfaction of the conditions precedent specified herein, and the prior receipt by the Company from the Investor of the Initial Exchanged Notes, the Company shall deliver the Initial Shares to the DTC account and the Cash Consideration by wire transfer to the account, in each case specified by the Investor for each relevant Exchanging Investor in Exhibit B.1.

On the Final Closing Date, subject to the Initial Closing having occurred, and the prior receipt by the Company from the Investor of the Final Exchanged Notes, the Company shall deliver the Final Settlement Shares to the DTC account specified by the Investor for each relevant Exchanging Investor in Exhibit B.1.

All questions as to the form of all documents and the validity and acceptance of the Exchanged Notes and the Exchange Consideration will be determined by the Company, in its sole discretion, which determination shall be final and binding. Subject to the terms and conditions of this Agreement, upon the delivery of the Exchange Consideration, the Investor hereby, for itself and on behalf of its Accounts, irrevocably (a) waives any and all other rights with respect to such Exchanged Notes and (b) releases and discharges the Company and Goldman Sachs & Co. LLC (the “Placement Agent”) from any and all claims, actions, causes or rights, whether known or unknown, contingent or matured, that the undersigned and its Accounts may now have, or may have in the future, arising out of, or related to, such Exchanged Notes.

(a)The Company and each of its subsidiaries are entities duly organized, validly existing and in good standing under the laws of their respective jurisdictions of incorporation and have the requisite power and authority to own their properties and to carry on their business as now being conducted, except in the case of the Company’s subsidiaries as would not reasonably be expected to have a material adverse effect on the business, properties, assets, liabilities, operations (including results thereof), or financial condition of the Company and its subsidiaries, taken as a whole (a “Material Adverse Effect”). The Company and each of its subsidiaries is duly qualified as a foreign entity to do business (where such concept exists) and is in good standing in every jurisdiction (where such concept exists) in which its ownership of property or the nature of the business conducted by it makes such qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not reasonably be expected to have a Material

Adverse Effect. The Company has the power and authority to execute and deliver this Agreement, to perform its obligations hereunder, and to consummate the Exchange contemplated hereby.

(b)This Agreement has been duly authorized, executed and delivered by the Company and constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except that such enforcement may be subject to (A) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws affecting or relating to enforcement of creditors’ rights generally and (B) general principles of equity, whether such enforceability is considered in a proceeding at law or in equity (the “Enforceability Exceptions”).

No consent, approval, order or authorization of, or registration, declaration or filing with any governmental entity or non-governmental regulatory authorities (including The NYSE American, other than the filing with The New York Stock Exchange of a supplemental listing application of the Shares, which the Company will so file) is required on the part of the Company or any of its subsidiaries in connection with the execution, delivery and performance by the Company of this Agreement and the consummation by the Company of the Exchange, except as may be required under any state or federal securities laws or that may be made or obtained after the applicable Closing without penalty or such that would not, individually or in the aggregate, reasonably be expected to materially impair the ability of the Company to perform its obligations under this Agreement or to consummate the transactions contemplated by this Agreement.

(d)When issued, delivered and paid for in the manner set forth in this Agreement, the Shares will (i) be validly issued, fully paid and non-assessable, (ii) be free and clear of any Liens (as defined in Section 3(c) below), option, equity or other adverse claim thereto, including claims or rights under any voting trust agreements, shareholder agreements or other agreements to which the Company is a party, and (iii) will not be subject to any preemptive, participation, rights of first refusal or other similar rights under the General Corporation Law of the State of Delaware or any agreements to which the Company is a party (other than any such rights that will be waived prior to the applicable Closing).

As of their respective dates, the SEC Documents complied in all material respects with the requirements of the Exchange Act and the rules and regulations of the SEC promulgated thereunder applicable to the SEC Documents.

The Investor and each Exchanging Investor has considered the suitability of the Shares as an investment in light of the Investor and such Exchanging Investor’s circumstances and financial condition and is able to bear the risks associated with an investment in the Shares.

(h)The Investor confirms that it and each Exchanging Investor is not relying on any communication (written or oral) of the Company, the Placement Agent or any of their respective affiliates or representatives as investment advice or as a recommendation to acquire the Shares in the Exchange. It is understood that information provided by the Company, the Placement Agent or any of their respective affiliates and representatives shall not be considered investment advice or a recommendation to participate in the Exchange, and that none of the Company, the Placement Agent or any of their respective affiliates or representatives is acting or has acted as an advisor to the Investor or any Exchanging Investor in deciding to participate in the Exchange.

(i)The Investor confirms that the Company has not (i) given the Investor or any Exchanging Investor any guarantee, representation or warranty as to the potential success, return, effect or benefit (either legal, regulatory, tax, financial, accounting or otherwise) of an investment in the Shares or (ii) made any representation or warranty to the Investor or any Exchanging Investor regarding the legality of an investment in the Shares under applicable legal investment or similar laws or regulations. The Investor confirms that it and each Exchanging Investor is not relying and has not relied, upon any statement, advice (whether accounting, tax, financial legal or other), representation or warranty by the Company or any of its affiliates or representatives, including, without limitation, the Placement Agent, its affiliates and its or their directors, officers, employees, representatives and controlling persons, except for the representations and warranties made by the Company in this Agreement, and that the Investor has made its own independent decision that the investment in the Shares is suitable and appropriate for the Investor and the Exchanging Investors.

The Investor and each Exchanging Investor has been offered the opportunity to ask such questions of the Company and its representatives and received answers thereto, as it deems necessary to enable it to make an informed investment decision concerning the Exchange.

(k)Each Exchanging Investor is an institutional “accredited investor” as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act, an “Institutional Account” as defined in FINRA Rule 4512(c) and a “qualified institutional buyer” as defined in Rule 144A under the Securities Act and agrees not to reoffer or resell the Shares except pursuant to an exemption from registration under the Securities Act or pursuant to an effective registration statement thereunder (it being understood, however, that the disposition of such person’s property shall at all times be within such person’s control).

To the Investor’s knowledge, no Exchanging Investor acquired any of the Notes, directly or indirectly, from an Affiliate of the Company.

(m)Each Exchanging Investor is acquiring the Shares solely for its own beneficial account, for investment purposes, and not with a view to, or for resale in connection with, any distribution of the Shares. The Investor and each Exchanging Investor understands that the offer and sale of the Shares have not been registered under the Securities Act or any state securities laws and the Shares are being issued without registration under the Securities Act pursuant to Section 4(a)(2) of the Securities Act, which exemption depends in part upon the investment intent of the Exchanging Investors and the accuracy of the other representations and warranties made by the Investor on behalf of the Exchanging Investors in this Agreement.

(v)The Investor and each Exchanging Investor understands that no federal, state, local or foreign agency has passed upon the merits or risks of an investment in the Shares or made any finding or determination concerning the fairness or advisability of this investment.

Under U.S. federal income tax law, a holder who exchanges Notes for Shares and/or Cash Payment generally must provide such holder’s correct TIN on a properly completed and executed IRS Form W-9 (available from the Company or at www.irs.gov/pub/irs-pdf/fw9.pdf) or otherwise establish a basis for exemption from backup withholding. A TIN is generally an individual holder’s social security number or a holder’s employer identification number. If the correct TIN is not provided, the holder may be subject to a $50 penalty imposed under Section 6723 of the Code. In addition, certain payments made to holders may be subject to U.S. backup withholding (currently set at 24% of the payment). If a holder is required to provide a TIN but does not have a TIN, the holder should consult its tax advisor regarding how to obtain a TIN. Certain holders (including corporations and non-U.S. holders) are not subject to these backup withholding and reporting requirements.

A non-U.S. holder (i) will be subject to 30% U.S. federal withholding unless such holder establishes an exemption from, or a reduced rate of, such withholding, and (ii) must establish its status as an exempt recipient from backup withholding and can do so by submitting a properly completed IRS Form W-8BEN, IRS Form W-8BEN-E, IRS Form W-8IMY (and all required attachments), or other applicable IRS Form W-8 (available from the Company or at www.irs.gov), signed, under penalties of perjury, attesting to such holder’s exempt foreign status. This form also may establish an exemption from withholding under Section 1471 through 1474 of the Code.

U.S. backup withholding is not an additional tax. Rather, the U.S. federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained provided that the required information is timely furnished to the IRS. Exchanging Investors are urged to consult their tax advisors regarding how to complete the appropriate forms and to determine whether they are exempt from backup withholding or other withholding taxes.

Summary of Significant Accounting Policies (Policies)	6 Months Ended
Summary of Significant Accounting Policies (Policies)	Jun. 30, 2023
Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and the instructions to Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. Although the Company considers the disclosures in these unaudited consolidated financial statements to be adequate to make the information presented not misleading, certain information or footnote information normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted under the rules and regulations of the SEC. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of financial position at June 30, 2023, and December 31, 2022, results of operations, comprehensive income (loss), and changes in stockholder’s deficit for the three and six months ended June 30, 2023 and 2022 and cash flows for the six months ended June 30, 2023 and 2022 have been included. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 16, 2023. The interim results for June 30, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023, or for any future interim periods. The consolidated financial statements reflect the accounts of Senseonics Holdings, Inc. and its wholly owned operating subsidiary Senseonics, Incorporated. The Company views its operations and manages its business in one segment, glucose monitoring products. Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires entities to record expected credit losses for certain financial instruments, including trade receivables, as an allowance that reflects the entity's current estimate of credit losses expected to be incurred. For available-for-sale debt securities in unrealized loss positions, the new standard requires allowances to be recorded instead of reducing the amortized cost of the investment. The Company currently holds investments in available-for-sale securities. The Company has not historically experienced collection issues or bad debts with trade receivables. Accordingly, the Company does not expect this to have a significant impact on its consolidated financial statements and related disclosures at this time. The Company adopted this guidance as of January 1, 2023 and its adoption did not have a material impact on the consolidated financial statements and related disclosures.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and expenses during the reporting period. In the accompanying unaudited consolidated financial statements, estimates are used for, but not limited to, stock-based compensation, recoverability of long-lived assets, deferred taxes and valuation allowances, fair value of investments, derivative assets and liabilities, obsolete inventory, warranty obligations, variable consideration related to revenue, bad debts, depreciable lives of property and equipment, and accruals for clinical study costs, which are accrued based on estimates of work performed under contract. The Company bases these estimates on historical and anticipated results, trends, and various other assumptions that it believes are reasonable, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities and recorded revenues and expenses. Actual results could differ from those estimates; however, management does not believe that such differences would be material.
