Notes to Unaudited Condensed Consolidated Financial Statements

1.Organization

Senseonics Holdings, Inc. (the “Company”), a Delaware corporation, is a medical technology company focused on the design, development and commercialization of glucose monitoring products to improve the lives of people with diabetes by enhancing their ability to manage their disease with relative ease and accuracy.

ASN Technologies, Inc. (“ASN”) was incorporated in Nevada on June 26, 2014. On December 4, 2015, ASN reincorporated in Delaware and changed its name to Senseonics Holdings, Inc. On December 7, 2015, Senseonics Holdings, Inc. acquired 100% of the outstanding capital stock of Senseonics, Incorporated (the "Acquisition"). Senseonics, Incorporated was originally incorporated on October 30, 1996 and commenced operations on January 15, 1997. Senseonics Holdings and its wholly-owned subsidiary Senseonics, Incorporated are hereinafter referred to as the “Company” unless the context requires otherwise.

2.Liquidity

The Company’s operations are subject to certain risks and uncertainties including, among others, current and potential competitors with greater resources, lack of operating history and uncertainty of future profitability. Since inception, the Company has incurred substantial operating losses, principally from expenses associated with the Company’s research and development programs. The Company has not generated significant revenues from the sale of products and its ability to generate revenue and achieve profitability largely depends on the Company’s ability, alone or with others, to complete the development of its products or product candidates, and to obtain necessary regulatory approvals for the manufacture, marketing and sales of those products. These activities, including planned significant research and development efforts, will require significant uses of working capital through the remainder of 2017 and beyond.

On March 23, 2016, the Company effected the initial closing of its public offering of 15,800,000 shares of its common stock at a price to the public of $2.85 per share (the “March 2016 Offering”). Additionally, the Company closed on the partial exercise of the underwriters’ option to purchase additional shares on April 5, 2016. The Company received aggregate net proceeds from the March 2016 Offering of $44.8 million. On June 30, 2016, the Company entered into Amended and Restated Loan and Security Agreement with Oxford Finance LLC (“Oxford”) and Silicon Valley Bank (“SVB”) to potentially borrow up to an aggregate principal amount of $30.0 million. On June 1, 2017, the Company effected the closing of its offering of 29,078,014 shares of its common stock at a price of $1.41 per share (the “May 2017 Offering”). The Company received aggregate net proceeds from the May 2017 Offering of $40.4 million. Management has concluded that, based on the Company’s current operating plans, its existing cash, cash equivalents, and marketable securities available for sale will be sufficient to meet the Company’s anticipated operating needs into the second quarter of 2018.  Accordingly, since management has concluded that the Company does not have sufficient funds to support operations through August 2018, the Company believes that doubt about the Company’s ability to continue as a going concern exists.

Historically, the Company has financed its operating activities through the sale of equity and equity linked securities and the issuance of debt. Although the Company began generating revenue from product sales of Eversense, its continuous glucose monitoring system, in June 2016, the Company does not expect product revenues to be sufficient to satisfy its operating needs for several years, if ever. Accordingly, the Company plans to continue financing its operations with external capital for the foreseeable future. However, the Company may not be able to raise additional funds on acceptable terms, or at all. If the Company is unable to secure sufficient capital to fund its research and development and other operating activities, the Company may be required to delay or suspend operations, enter into collaboration agreements with partners that could require the Company to share commercial rights to its products to a greater extent or at earlier stages in the product development process than is currently intended, merge or consolidate with other entities, or liquidate.

3.Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In the Company’s opinion, the accompanying unaudited interim condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly its financial position, results of operations, and cash flows. The consolidated balance sheet at December 31, 2016, has been derived from audited financial statements as of that date. The interim condensed consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year. Certain information and footnote disclosure normally included in financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to instructions, rules, and regulations prescribed by the U.S. Securities and Exchange Commission (“SEC”). The Company believes that the disclosures provided herein are adequate to make the information presented not misleading when these unaudited interim condensed consolidated financial statements are read in conjunction with the audited financial statements and notes previously included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.

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 revenues and expenses during the reporting period. In the accompanying consolidated financial statements, estimates are used for, but not limited to, stock-based compensation, recoverability of long-lived assets, deferred taxes and valuation allowances, depreciable lives of property and equipment, and estimated accruals for preclinical study costs, which are accrued based on estimates of work performed under contracts. Actual results could differ from those estimates; however management does not believe that such differences would be material.

Segment Information

Operating segments are defined as components of an enterprise about which separate discrete financial 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. The Company views its operations and manages its business in one segment, glucose monitoring products.

Comprehensive Loss

Comprehensive loss comprises net loss and other changes in equity that are excluded from net loss. For the three and six months ended June 30, 2017 and 2016, the Company’s net loss equaled its comprehensive loss and, accordingly, no additional disclosure is presented.

Cash Equivalents

The Company considers highly liquid investments with maturities of three months or less from the date of purchase to be cash equivalents. These investments are carried at cost, which approximates fair value.

Marketable Securities

Marketable securities consist of government and agency securities and corporate debt securities. The Company’s investments are classified as available for sale. Such securities are carried at fair value, with any unrealized holding gains or losses reported, net of any tax effects reported, as accumulated other comprehensive income. Realized gains and losses, and declines in value judged to be other-than-temporary, if any, are included in consolidated results of operations. A decline in the market value of any available for sale security below cost that is deemed to be other-than-temporary results in a reduction in fair value, which is charged to earnings in that period, and a new cost basis for the security is established. Dividend and interest income is recognized when earned. The cost of securities sold is calculated

using the specific identification method. The Company classifies all available-for-sale marketable securities with maturities greater than one year from the balance sheet date as non-current assets.

Inventory

Inventory is valued at the lower of cost or market (net realizable value). Cost is determined using the standard cost method that approximates first in, first out. The Company periodically reviews inventory to determine if a write down is necessary for inventory that has become obsolete, inventory that has a cost basis less than net realizable value, and inventory in excess of future demand taking into consideration the product shelf life.

Accounts Receivable

The Company grants credit to various customers in the normal course of business. Accounts receivable consist of amounts due from distributors. The Company records an allowance for doubtful accounts at the time potential collection risk is identified. Uncollectible accounts are written off against the allowance after appropriate collection efforts have been exhausted and when it is deemed that a balance is uncollectible.

Property and Equipment

Property and equipment are stated at historical cost and depreciated on a straight-line basis over the estimated useful lives, generally five years. Equipment under capital leases is depreciated on a straight-line basis over the lesser of its estimated useful life or the lease term. Leasehold improvements are depreciated over the shorter of the remaining lease term or useful lives of the assets. Upon disposition of the assets, the costs and related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations. Repairs and maintenance costs are included as expense in the accompanying statements of operations and comprehensive loss.

Management reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of the long-lived asset is measured by a comparison of the carrying amount of the asset to future undiscounted net cash flows expected to be generated by the asset. If the undiscounted cash flows are less than the carrying amount, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. Management did not identify any indicators of impairment through June 30, 2017.

Warranty Reserve

The Company generally provides a warranty on Eversense to end user customers and may replace Eversense components that do not function in accordance with the product specifications. Estimated warranty costs associated with a product are recorded at the time of shipment. The Company estimates future warranty costs by analyzing historical warranty experience for the timing and amount of returned product, and the Company evaluates the reserve quarterly and makes adjustments when appropriate.

Revenue Recognition

Revenue is generated from sales of sensor kits, transmitter kits, and related supplies under agreements for third-party distributors that resell the product to customers. The Company is paid for its sales directly by third-party distributors, regardless of whether or not the distributors resell the products to their customers.

The Company recognizes product sales revenue when all of the following criteria are met:

The Company offers no rights of return and has no significant post-delivery obligations and therefore, the above criteria are generally met as products are shipped to, or received by, third-party distributors.

Research and Development Costs

Research and development costs are expensed as incurred. Research and development expenses include costs related to employee compensation, preclinical studies and clinical trials, supplies, outsource testing, consulting and depreciation and other facilities‑related expenses.

Stock‑Based Compensation

The Company recognizes the cost of employee services received in exchange for awards of equity instruments, such as stock options, based on the fair value of those awards at the date of grant. The estimated fair value of stock options on the date of grant is amortized on a straight‑line basis over the requisite service period for each separately vesting portion of the award for those awards with service conditions only. For awards that also contain performance conditions, expense is recognized beginning at the time the performance condition is considered probable of being met over the remaining vesting period.

The Company uses the Black‑Scholes option pricing model to determine the fair value of stock‑option awards. Valuation of stock awards requires management to make assumptions and to apply judgment to determine the fair value of the awards. These assumptions and judgments include estimating the fair value of the Company’s common stock, future volatility of the Company’s stock price, dividend yields, future employee turnover rates, and future employee stock option exercise behaviors. Changes in these assumptions can affect the fair value estimate.

Under Accounting Standards Codification (“ASC”) 718, the cumulative amount of compensation cost recognized for instruments classified as equity that ordinarily would result in a future tax deduction under existing tax law shall be considered to be a deductible difference in applying ASC 740, Income Taxes. The deductible temporary difference is based on the compensation cost recognized for financial reporting purposes; however, these provisions currently do not impact the Company, as all the deferred tax assets have a full valuation allowance.

Since the Company had net operating loss (“NOL”) carryforwards as of June  30, 2017, no excess tax benefits for the tax deductions related to stock-based awards were recognized in the statements of operations and comprehensive loss.

Income Taxes

The Company uses the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that are in effect when the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that such tax rate changes are enacted. The measurement of a deferred tax asset is reduced, if necessary, by a valuation allowance if it is more likely than not that some portion or all of the deferred tax asset will not be realized.

Management uses a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return, as well as guidance on derecognition, classification, interest and penalties and financial statement reporting disclosures. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. In the ordinary course of business, transactions occur for which the ultimate outcome may be uncertain. Management does not expect the outcome related to accrued uncertain tax provisions to have a material adverse effect on the Company’s financial position, results of operations or cash flows.  The Company recognizes interest and penalties accrued on any unrecognized tax exposures as a component of income tax expense. The Company did not have any amounts accrued relating to interest and penalties as of June 30, 2017 and December 31, 2016.

The Company is subject to taxation in various jurisdictions in the United States and remains subject to examination by taxing jurisdictions for the year 1998 and all subsequent periods due to the availability of NOL carryforwards. In addition, all of the NOLs and research and development credit carryforwards that may be used in future years are still subject to adjustment.

Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses  approximate fair value because of their short maturities. Based on the borrowing rates currently available for loans with similar terms, the Company believes that the fair value of its long-term notes payable approximates its carrying value.

Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period.

For periods of net loss, diluted net loss per share is calculated similarly to basic loss per share because the impact of all potential dilutive common shares is anti‑dilutive. The total number of anti‑dilutive shares, which have been excluded from the computation of diluted loss per share, was 15,348,333 and 11,354,147  common stock options and 4,570,902 and 5,127,176 stock purchase warrants exercisable for common stock as of June 30, 2017 and 2016, respectively.

For periods of net income, and when the effects are not anti-dilutive, diluted earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of shares outstanding plus the impact of all potential dilutive common shares, consisting primarily of common stock options and stock purchase warrants using the treasury stock method.

Recent Accounting Pronouncements

Recently Adopted

In July 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2015-11, which requires that inventory accounted for under the first-in, first-out or average cost methods be measured at the lower of cost and net realizable value, where net realizable value represents the estimated selling price of inventory in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company adopted the guidance in the first quarter of fiscal year 2017. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

Not Yet Adopted

In May 2014, the FASB issued ASU 2014-09, guidance for revenue recognition for contracts, superseding the previous revenue recognition requirements, along with most existing industry-specific guidance. The guidance requires an entity to review contracts in five steps: 1) identify the contract, 2) identify performance obligations, 3) determine the transaction price, 4) allocate the transaction price, and 5) recognize revenue. The new standard will result in enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenue arising from contracts with customers. In August 2015, the FASB issued guidance approving a one-year deferral, making the standard effective for reporting periods beginning after December 15, 2017, with early adoption permitted only for reporting periods beginning after December 15, 2016. In March 2016, the FASB issued guidance to clarify the implementation guidance on principal versus agent considerations for reporting revenue gross rather than net, with the same deferred effective date. In April 2016, the FASB issued guidance to clarify the implementation guidance on identifying performance obligations and the accounting for licenses of intellectual property, with the same deferred effective date. In May 2016, the FASB issued guidance rescinding SEC paragraphs related to revenue recognition, pursuant to two SEC Staff Announcements at the March 3, 2016 Emerging Issues Task Force meeting. In May 2016, the FASB also issued guidance to clarify the implementation guidance on assessing collectability, presentation of sales tax, noncash consideration, and contracts and

contract modifications at transition, with the same effective date. The Company plans to adopt the guidance on January 1, 2018 using the full retrospective method. The Company expects the adoption of the guidance to have an immaterial impact to its consolidated financial statements based on its current revenue model. 

In February 2016, the FASB issued ASU 2016-02, guidance for accounting for leases. The guidance requires lessees to recognize assets and liabilities related to long-term leases on the balance sheet and expands disclosure requirements regarding leasing arrangements. The guidance is effective for reporting periods beginning after December 15, 2018 and early adoption is permitted. The guidance must be adopted on a modified retrospective basis and provides for certain practical expedients. The Company is currently evaluating the impact of adopting the guidance will have on its consolidated financial statements.

In August 2016, the FASB issued ASU 2016-015, guidance on the classification of certain cash receipts and cash payments in the statements of cash flows, including those related to debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance, and distributions received from equity method investees. The guidance is effective for public business entities for fiscal years beginning after December 15, 2017, and for interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. If an entity adopts the guidance in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The guidance must be adopted on a retrospective basis and must be applied to all periods presented, but may be applied prospectively if retrospective application would be impracticable. The Company is currently evaluating the impact of adopting the guidance will have on its consolidated statements of cash flows.

The Company has evaluated all other issued unadopted Accounting Standards Updates and believes the adoption of these standards will not have a material impact on its consolidated statements of earnings, balance sheets, or cash flows.

On March 31, 2016 the Company amended a corporate development agreement with a supplier to include a minimum purchase commitment per year. Total research and development expense related to the minimum payment was $467,746 and $141,000 for the three months ended June 30, 2017 and 2016, respectively, and $525,621 and $253,890 for the six months ended June 30, 2017 and 2016, respectively. There were approximately $1.8 million of future minimum payments under this commitment at June  30, 2017.

8.401(k) Plan

The Company has a defined contribution 401(k) plan available to all full-time employees. Employee contributions are voluntary and are determined on an individual basis subject to the maximum allowable under federal income tax regulations. Participants are fully vested in their contributions. There have been no employer contributions to this plan. Administrative expenses for the plan, which are paid by the Company, were not material in the three and six months ended June  30,  2017.

9.Notes Payable

Term Notes Payable

On June 30, 2016, the Company entered into an Amended and Restated Loan and Security Agreement with Oxford and SVB (the “Lenders”). Pursuant to the Amended and Restated Loan and Security Agreement, the Company may potentially borrow up to an aggregate principal amount of $30.0 million in the following four tranches: $15.0 million (“Tranche 1 Term Loan”); $5.0 million (“Tranche 2 Term Loan”); $5.0 million (“Tranche 3 Term Loan”); and $5.0 million (“Tranche 4 Term Loan”) (each, a “Term Loan,” and collectively, the “Term Loans”). The funding conditions for the Tranche 1 Term Loan were satisfied as of June 30, 2016. Therefore, the Company issued secured notes to the Lenders for aggregate gross proceeds of $15.0 million (the “Notes”) on June 30, 2016. The Company used approximately $11.0 million from the proceeds from the Notes to repay the outstanding balance under the Company’s

previously existing Loan and Security Agreement with Oxford, dated as of July 31, 2014, including the applicable final payment fee due thereunder of $1 million. The Company borrowed the Tranche 2 Term Loan in November 2016 upon the Lenders’ confirmation that the Company received positive data in its U.S. pivotal trial of Eversense, and the Company submitted a pre-market approval (“PMA”) application for Eversense in the United States with the FDA. The Company borrowed the Tranche 3 Term Loan in March 2017 upon completion of the first commercial sale of its second-generation transmitter in the European Union. The Company may borrow the Tranche 4 Term Loan on or before December 31, 2017 if it receives PMA approval from the FDA for Eversense, and achieves trailing six-month revenue for the applicable period of measurement of at least $4.0 million. The maturity date for all Term Loans is June 1, 2020 (the “Maturity Date”).

The Term Loans bear interest at a floating annual rate of 6.31% plus the greater of (i) 90-day U.S. Dollar LIBOR reported in the Wall Street Journal or (ii) 0.64%, provided that the minimum floor interest rate is 6.95%, and require monthly payments. The monthly payments initially consist of interest-only.  After 18 months, the monthly payments will convert to payments of principal and monthly accrued interest, with the principal amount being amortized over the ensuing 30 months.

The Company may elect to prepay all Term Loans prior to the Maturity Date subject to a prepayment fee equal to 3.00% if the prepayment occurs within one year of the funding date of any Term Loan, 2.00% if the prepayment occurs during the second year following the funding date of any Term Loan, and 1.00% if the prepayment occurs more than two years after the funding date of any Term Loan and prior to the Maturity Date. 

The Amended and Restated Loan and Security Agreement contains customary events of default, including bankruptcy, the failure to make payments when due, the occurrence of a material impairment on the Lenders’ security interest over the collateral, a material adverse change, the occurrence of a default under certain other agreements entered into by the Company, the rendering of certain types of judgments against the Company, the revocation of certain government approvals of the Company, violation of covenants, and incorrectness of representations and warranties in any material respect.  Upon the occurrence of an event of default, subject to specified cure periods, all amounts owed by the Company would begin to bear interest at a rate that is 5.00% above the rate effective immediately before the event of default, and may be declared immediately due and payable by Lenders.

Pursuant to the Amended and Restated Loan and Security Agreement, the Company also issued 10-year stock purchase warrants to purchase an aggregate of 116,581,  63,025 and 80,645 shares of common stock at an exercise price of $3.86,  $2.38 and $1.86 per share, respectively (see Note 10).

The Notes are collateralized by all of the Company’s consolidated assets other than its intellectual property. The Notes also contain certain restrictive covenants that limit the Company’s ability to incur additional indebtedness and liens, merge with other companies or consummate certain changes of control, acquire other companies, engage in new lines of business, make certain investments, pay dividends, transfer or dispose of assets, amend certain material agreements or enter into various specified transactions, as well as financial reporting requirements. The Company incurred issuance costs related to the Notes of approximately $568,648 that are being amortized as additional interest expense over the term of the Notes using the effective interest method. The fair value of the stock purchase warrants, which was estimated to be $526,209, was recorded as a discount to the Notes, which is also being amortized as additional interest expense over the term of the Notes using the effective interest method.

At maturity (or earlier prepayment), the Company is also required to make a final payment equal to 9.00% of the aggregate principal balances of the funded Term Loans. This fee is being accrued as additional interest expense over the term of the Notes using the effective interest method. In the event that the Company achieves the requirements to borrow the Tranche 4 Term Loan, and elects not to borrow the Tranche 4 Term Loan, the Company is obligated to pay the Lenders a non-utilization fee of 2.00% of the undrawn amounts.

The following are the scheduled maturities of the Term Loans as of June 30, 2017 (in thousands):

10.Stockholders’ Equity (Deficit)

Preferred Stock

As of June 30, 2017 and December 31, 2016, the Company’s authorized capital stock included 5,000,000 shares of undesignated preferred stock, par value $0.001 per share.  No shares of preferred stock were outstanding as of June 30, 2017 or December 31, 2016.

Common Stock

As of June 30, 2017 and December 31, 2016, the Company’s authorized capital stock included 250,000,000 shares of common stock, par value $0.001 per share. The Company had 123,186,466 and 93,569,642 shares of common stock issued and outstanding at June 30, 2017 and December 31, 2016, respectively.

Stock Purchase Warrants

In connection with the issuance of the Notes, the Company also issued to the Lenders 10-year stock purchase warrants to purchase an aggregate of 116,581,  63,025 and 80,645 shares of common stock at an exercise price of $3.86,  $2.38 and $1.86 per share, respectively. The fair value of the warrants, which the Company estimated to be $526,209, was recorded as a discount to the Notes. These warrants expire on June 30, 2026, November 22, 2026, and March 29, 2027, respectively, and are classified in equity. In connection with the Company’s original Loan and Security Agreement with Oxford in 2014, the Company issued to Oxford 10-year stock purchase warrants to purchase an aggregate of 167,570 shares of common stock at an exercise price of $1.79 per share. The fair value of the warrants, which the Company estimated to be $205,150, was recorded as a discount to the promissory notes issued to Oxford in connection with the original Loan and Security Agreement. These warrants expire on November 2, 2020, July 14, 2021 and August 19, 2021, and are classified in equity. The unamortized deferred financing fees and debt discount related to the notes rollover amount will be amortized along with the deferred financing costs and the discount created by the new issuance of the warrants over the term of the loan using the effective interest method. For the three months ended June 30, 2017 and 2016, the Company recorded amortization of discount of debt of $58,150 and $12,683, respectively, and for the six months ended June 30, 2017 and 2016, the Company recorded amortization of discount of debt of $111,798 and $27,010, respectively, within interest expense in the accompanying statements of operations and comprehensive loss.

Restricted Stock Awards

The Company issued 398,525 shares of restricted stock to the chairman of the Company’s board of directors (the “Chairman”) in December 2015, half of which were vested upon grant and half of which vested upon the completion of the March 2016 Offering, pursuant to an agreement between the Company and the Chairman, as described in greater detail in Note 11. In June 2016, the Company issued a fully vested restricted stock award for 300,000 shares of common stock to the Chairman to settle the outstanding obligations under the agreement. The Company recognized stock-based compensation expense of $378,470 and $1.2 million in the three and six months ended June 30, 2016, respectively, related to the grant and vesting of this restricted stock. For the three and six months ended June 30, 2017, no compensation expense was recognized related to the grant or vesting of restricted stock.

Stock‑Based Compensation

In December 2015, the Company adopted the 2015 Equity Incentive Plan (the “2015 Plan”) under which incentive stock options and non-qualified stock options may be granted to the Company’s employees and certain other persons in accordance with the 2015 Plan provisions. In connection with the March 2016 Offering, the Company’s board of directors adopted and the Company’s stockholders approved an Amended and Restated 2015 Equity Incentive Plan (the “amended and restated 2015 Plan”). The amended and restated 2015 Plan became effective as of the date of the pricing of the March 2016 Offering. The Company’s board of directors may terminate the amended and restated 2015 Plan at any time. Options granted under the amended and restated 2015 Plan expire ten years after the date of grant.

Pursuant to the amended and restated 2015 Plan, the number of shares initially reserved for issuance pursuant to equity awards was 17,251,115 shares, representing 8,000,000 shares plus up to an additional 9,251,115 shares in the event that options that were outstanding under the Company’s equity incentive plans as of February 16, 2016 expire or otherwise terminate without having been exercised (in such case, the shares not acquired will revert to and become available for issuance under the amended and restated 2015 Plan). The number of shares of the Company’s common stock reserved for issuance under the amended and restated 2015 Plan will automatically increase on January 1 of each year, beginning on January 1, 2017 and ending on January 1, 2026, by 3.5% of the total number of shares of the Company’s common stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares as may be determined by the Company’s board of directors. As of June 30, 2017,  3,884,452 shares remained available for grant under the amended and restated 2015 Plan.

On May 8, 1997, the Company adopted the 1997 Stock Option Plan (the “1997 Plan”), under which incentive stock options and non‑qualified stock options may be granted to the Company’s employees and certain other persons in accordance with the 1997 Plan provisions. Approximately 8,492,171  shares of the Company’s common stock underlying options have vested or are expected to vest under the 1997 Plan. Upon the effectiveness of the 2015 Plan, the Company no longer grants any awards under the 1997 Plan.

The Company recognizes the cost of employee services received in exchange for awards of equity instruments, such as stock options, based on the fair value of those awards at the date of grant. The estimated fair value of stock options on the date of grant is amortized on a straight-line basis over the requisite service period for each separately vesting portion of the award for those awards with service conditions only. For awards that also contain performance conditions, expense is recognized beginning at the time the performance condition is considered probable of being met over the remaining vesting period. 

11.Related Party Transactions

In December 2015, the Chairman received a restricted stock award of 398,525 shares of common stock pursuant to an agreement entered into with the Company (the “December Agreement”) that superseded a pre-existing agreement. One half of the shares covered by this restricted stock award were fully vested on grant. The remainder vested in full upon the completion of the Company’s March 2016 Offering, which was the specific performance condition of the award. Additionally, as a result of the completion of the March 2016 Offering, pursuant to the December Agreement, the Chairman was entitled to receive estimated compensation in the amount of $785,000.  In June 2016, the Chairman received a restricted stock award of 300,000 shares of common stock pursuant to an agreement entered into with the Company that superseded the December Agreement and satisfied the outstanding compensation obligation under the December Agreement. All of the shares covered by this restricted stock award were fully vested on date of grant.

12.Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to settle a liability in an orderly transaction between market participants at the measurement date. Fair value has a three level hierarchy from highest priority (Level 1) to lowest priority (Level 3). The fair value hierarchy reflects whether the inputs are observable from

independent sources or rely on unobservable inputs based on the Company’s market assumptions. The three levels of the fair value hierarchy are described below:

The levels are not necessarily an indication of the risk of liquidity associated with the financial assets or liabilities disclosed.

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Company has segregated its financial assets and liabilities that are measured at fair value on a recurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the table below. The inputs used in measuring the fair value of the Company’s money market funds included in cash equivalents are considered to be Level 1 in accordance with the three-tier fair value hierarchy. The fair market values are based on period-end statements supplied by the various banks and brokers that held the majority of the funds.

The following table represents the fair value hierarchy of the Company’s financial assets and liabilities measured at fair value on a recurring basis (in thousands):

Financial Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

The Company has no financial assets and liabilities that are measured at fair value on a non-recurring basis.

Non-Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Company has no non-financial assets and liabilities that are measured at fair value on a recurring basis.

Non‑Financial Assets and Liabilities Measured at Fair Value on a Non‑Recurring Basis

The Company measures its long‑lived assets, including property and equipment, at fair value on a non‑recurring basis. These assets are recognized at fair value when they are deemed to be impaired. No such fair value impairment was recognized in the three and six months ended June 30, 2017 or June 30, 2016.

13.Income Taxes

The Company has not recorded any tax provision or benefit for the three and six months ended June 30, 2017 or June 30, 2016. The Company has provided a valuation allowance for the full amount of its net deferred tax assets since realization of any future benefit from deductible temporary differences, NOL carryforwards and research and development credits is not more-likely-than-not to be realized at June 30, 2017 and December 31, 2016.

14.Litigation

From time to time, the Company is subject to litigation and claims arising in the ordinary course of business. The Company accrues for litigation and claims when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company has evaluated claims in accordance with the accounting guidance for contingencies that it deems both probable and reasonably estimable and, accordingly, has recorded aggregate liabilities for all claims of approximately $40,000 as of December 31, 2016. These amounts are reported on the consolidated balance sheets within accrued and other liabilities and other noncurrent liabilities. This liability was settled for $43,237 on April 4, 2017. As of June 30, 2017, there were  no recorded liabilities related to pending litigation, claims arising from the ordinary course of business, or other legal matters.

Overview

We were originally incorporated as ASN Technologies, Inc. in Nevada on June 26, 2014. On December 4, 2015, we were reincorporated in Delaware and changed our name to Senseonics Holdings, Inc. Also, on December 4, 2015, we entered into a merger agreement with Senseonics, Incorporated and SMSI Merger Sub, Inc., or the Merger Agreement, to acquire Senseonics, Incorporated. Senseonics, Incorporated was originally incorporated on October 30, 1996 and commenced operations on January 15, 1997. The transactions contemplated by the Merger Agreement were consummated on December 7, 2015, referred to herein as the Acquisition. Pursuant to the terms of the Merger Agreement, (i) all issued and outstanding shares of Senseonics, Incorporated's preferred stock were converted into shares of Senseonics, Incorporated common stock, $0.01 par value per share, or the Senseonics Shares, (ii) all outstanding Senseonics Shares were exchanged for 57,739,953 shares of our common stock, $0.001 par value per share, or the Company Shares, reflecting an exchange ratio of one Senseonics Share for 2.0975 Company Shares, or the Exchange Ratio, and (iii) all outstanding options and warrants to purchase Senseonics Shares, or the Senseonics Options and Senseonics Warrants, respectively, were each exchanged or replaced with options and warrants to acquire shares of our common stock, or the Company Options and Company Warrants, respectively. Accordingly, Senseonics, Incorporated became our wholly-owned subsidiary.

Following the closing of the Acquisition, the business of Senseonics, Incorporated became our sole focus and all of our operations following the closing of the Acquisition consist of the historical Senseonics, Incorporated business. Unless otherwise indicated or the context otherwise requires, all references in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section to "the Company," "we," "our," "ours," "us" or similar terms refer to (i) Senseonics, Incorporated prior to the closing of the Acquisition, and (ii) Senseonics Holdings, Inc. and its subsidiaries subsequent to the closing of the Acquisition and all share and per share information in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section gives retroactive effect to the exchange of Senseonics Shares, Senseonics Options and Senseonics Warrants for Company Shares, Company Options and Company Warrants, respectively, in the Acquisition, as well as the corresponding exercise price adjustments for the such options and warrants.

We are a medical technology company focused on the design, development and commercialization of glucose monitoring products to improve the lives of people with diabetes by enhancing their ability to manage their disease with relative ease and accuracy. Our first generation continuous glucose monitoring, or CGM, system, Eversense, is a reliable,

long‑term, implantable CGM system that we have designed to continually and accurately measure glucose levels in people with diabetes for a period of up to 90 days, as compared to seven days for currently available CGM systems. We believe Eversense will provide people with diabetes with a more convenient method to monitor their glucose levels in comparison with the traditional method of self‑monitoring of blood glucose, or SMBG, as well as currently available CGM systems. In our European pivotal clinical trial, we observed that Eversense measured glucose levels over 90 days with a degree of accuracy comparable or superior to that of other currently available CGM systems.

Corporate History

From our founding in 1996 until 2010, we devoted substantially all of our resources to researching various sensor technologies and platforms. Beginning in 2010, we narrowed our focus to designing, developing and refining a commercially viable glucose monitoring system. On May 10, 2016, we received regulatory approval to commercialize Eversense in Europe. In June 2016, we made our first product shipment of Eversense through our distribution agreement with Rubin Medical, or Rubin. Since our inception, we have funded our activities primarily through equity and debt financings.

In March 2016, we completed a public offering of our common stock, or the March 2016 Offering, selling 15,800,000 shares of common stock at a price to the public of $2.85 per share, for aggregate gross proceeds of $45.0 million. Net cash proceeds from the March 2016 Offering were approximately $40.9 million, after deducting underwriting discounts and commissions and estimated offering-related transaction costs payable by us. In April 2016, the underwriters for the March 2016 Offering partially exercised their option to purchase additional shares of common stock, purchasing an additional 1,439,143 shares, from which we received additional net cash proceeds of approximately $3.9 million, after deducting underwriting discounts and commissions and estimated offering-related transaction costs payable by us.

On June 30, 2016 we entered into an Amended and Restated Loan and Security Agreement with Oxford Finance LLC, or Oxford, and Silicon Valley Bank, or SVB, to potentially borrow up to an aggregate principal amount of $30.0 million. Under the terms of the agreement, we initially borrowed an aggregate of $15 million from Oxford and SVB on June 30, 2016. We used $11 million of the $15 million to retire existing loans with Oxford, including a final payment fee of $1 million. In each of November 2016 and March 2017, we borrowed an additional $5 million upon achieving certain milestones. The agreement also permits us to borrow up to an additional $5 million upon the achievement of specified milestones through the end of 2017. The agreement provides for monthly payments of interest only for a period of 18 months, followed by an amortization period of 30 months.

In June 2017, we completed an underwritten offering of our common stock, or the May 2017 Offering, selling 29,078,014 shares of common stock at a price of $1.41 per share, for aggregate gross proceeds of $41.0 million. Net cash proceeds from the May 2017 Offering were approximately $40.4 million, after deducting underwriting discounts and commissions and estimated transaction costs payable by us.

We have never been profitable and our net losses were $12.4 million and $11.9 million for three months ended June 30, 2017 and 2016, respectively, and $25.4 million and $23.1 million for the six months ended June 30, 2017 and 2016, respectively. As of June 30, 2017, our accumulated deficit totaled $230.2 million, primarily as a result of expenses incurred in connection with our research and development programs and from general and administrative expenses associated with our operations. We expect to continue to incur significant expenses and increasing operations and net losses for the foreseeable future.

European Development and Commercialization of Eversense

In July 2015, we applied for, and in May 2016, we received our CE mark, which allows us to market and sell Eversense in Europe. In connection with our CE Mark, we have agreed to conduct post market surveillance activities. In June 2016, we commenced commercialization of Eversense in Sweden through our distribution agreement with Rubin, which also has the right to distribute Eversense in Norway and Denmark. Rubin markets and sells medical products for diabetes treatment in the Scandinavian region, including as the exclusive Scandinavian distributor for the insulin pump manufacturer Animas Corporation.

In May 2016, we entered into a distribution agreement with Roche Diagnostics International AG and Roche Diabetes Care GmbH, together referred to as Roche, pursuant to which we granted Roche the exclusive right to market, sell and distribute Eversense in Germany, Italy and the Netherlands.  In November 2016, we entered into an amendment to the distribution agreement granting Roche the exclusive right to market, sell and distribute Eversense in Europe, the Middle East and Africa, excluding Sweden, Norway, Denmark, Finland and Israel. Roche is a pioneer in the development of blood glucose monitoring systems and a global leader for diabetes management systems and services. We began distributing Eversense through Roche in Germany in September 2016 and in Italy and the Netherlands in the fourth quarter of 2016.

We continue to expand our Eversense line of product offerings and expect to receive a CE Mark for Eversense XL, which will indicate a sensor life to up to 180 days, in the third quarter of 2017. We plan to begin to commercialize Eversense XL in Europe by the end of 2017. We are also developing Eversense Now, an application designed to remotely monitor the Eversense users’ CGM data in real time. We expect to receive approval to market Eversense Now in Europe by the end of 2017.

United States Development 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, or MARD, of 8.8% 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. We also observed a MARD of 9.5% utilizing one calibration point 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, or PMA, application to the FDA to market Eversense in the United States. While we expect that the PMA process can take as long as 18 months, we are currently anticipating approval by the end of 2017. However, the ultimate timing of PMA approval is uncertain and will depend on many factors, including whether the FDA would require the review of Eversense by an advisory panel and the related logistics of convening a panel, the degree and nature of questions raised by the FDA in its review process, and our ability to submit additional data or other information that adequately addresses questions raised by the FDA. Accordingly, we cannot guarantee the timing of receipt of PMA approval, if at all. For commercialization in the United States, we intend to distribute our product through our own direct sales and marketing organization. We have received Category III CPT codes for the insertion and removal of the Eversense sensor. Following PMA approval, we intend to pursue a Category I CPT code.

We expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. In addition, we expect that our expenses will increase substantially as we continue the research and development of our other products and maintain, expand and protect our intellectual property portfolio and seek regulatory approvals in other jurisdictions. Furthermore, we expect to continue to incur additional costs associated with operating as a public company, including significant legal, accounting, investor relations and other expenses that we did not incur as a private company. We will need to obtain substantial additional funding in connection with our continuing operations through public or private equity or debt financings or other sources, which may include collaborations with third parties. However, we may be unable to raise additional funds when needed on favorable terms or at all. Our failure to raise such capital as and when needed would have a material and adverse impact on our financial condition and our ability to develop and commercialize Eversense and future products and our ability to pursue our business strategy. We will need to generate significant revenues to achieve profitability, and we may never do so.

Financial Overview

Revenue

During the three and six months ended June 30, 2017, we generated product revenue from sales of the Eversense system in Europe pursuant to distribution agreements with Roche and Rubin, and we expect to continue marketing Eversense in additional European countries during 2017.  We expect our revenue from European product sales will increase as we ramp up our commercialization efforts through the remainder of 2017 and into 2018. In the future, subject to regulatory approval, we also intend to seek to commercialize Eversense in the United States, as well as other

international markets. If we fail to successfully commercialize or are otherwise unable to complete the development of Eversense, our ability to generate future revenue, and our results of operations and financial position, will be adversely affected.

Cost of Sales

We utilize contract manufacturers to produce Eversense. Cost of sales consists primarily of the components of Eversense and assembly, as well as reserves for warranty costs. Other cost of sales includes distribution-related expenses such as logistics and shipping costs of Eversense to Roche and Rubin for distribution in various regions in Europe, the Middle East and Africa. We calculate gross margin as revenue less costs of sales divided by revenue. We expect our overall gross margin to improve over the long term, as our sales increase and we have more opportunities to spread our costs over larger production volumes. However, our gross margins may fluctuate from period to period.

Sales and Marketing

Sales and marketing expenses consist primarily of salaries and other related costs, including stock‑based compensation, for personnel who perform sales and marketing functions. Other significant costs include promotional materials and tradeshow expenses.

We anticipate that our sales and marketing expenses will increase in the future as we continue to expand our commercialization of Eversense.

Research and Development

Research and development expenses consist of expenses incurred in performing research and development activities in developing Eversense, including our clinical trials and feasibility studies. Research and development expenses include compensation and benefits for research and development employees including stock‑based compensation, overhead expenses, cost of laboratory supplies, clinical trial and related clinical manufacturing expenses, costs related to regulatory operations, fees paid to contract research organizations and other consultants, and other outside expenses. Research and development costs are expensed as incurred.

We have incurred significant research and development expenses from inception, with the substantial majority of the expenses spent on the development of Eversense. We expect to continue to commit significant resources to continue to develop Eversense and future product enhancements and to conduct ongoing and future clinical trials. We expect that our overall research and development expenses will continue to increase in absolute dollars, but to decline as a percentage of total expenses as we expand the commercialization of Eversense.

General and Administrative

General and administrative expenses consist primarily of salaries and other related costs, including stock‑based compensation, for personnel in our executive, finance, accounting, business development, and human resources functions. Other significant costs include facility costs not otherwise included in research and development expenses, legal fees relating to patent and corporate matters and fees for accounting and consulting services.

Our general and administrative expenses have increased, and we expect them to continue to increase in the future, as a result of operating as a public company. These increases include increased costs related to the hiring of additional personnel and increased fees to outside consultants, lawyers and accountants as well as expenses related to maintaining compliance with NYSE-MKT listing rules and SEC requirements, insurance, and investor relations costs. These expenses may further increase when we no longer qualify as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, which will require us to comply with certain reporting requirements from which we are currently exempt.

Other Income (Expense), Net

Interest income consists of interest earned on our cash equivalents and interest expense primarily consists of interest expense on the secured notes, or the Notes, we issued to Oxford in connection with our original Loan and Security Agreement in July and December 2014 and the Notes we issued to Oxford and SVB in connection with our

Amended and Restated Loan and Security Agreement in June 2016, November 2016 and March 2017. We refer to Oxford and SVB together as the Lenders. This interest expense primarily consists of (i) contractual interest on the Notes, (ii) amortization of debt discount related to warrants, or the warrants, that we issued to the Lenders in connection with the Notes, and (iii) the accrual into interest expense of a final payment obligation that we are required to pay to the Lenders at maturity of the Notes. 

Results of Operations

Comparison of the Three Months Ended June 30, 2017 and 2016

The following table sets forth our results of operations for the three months ended June 30, 2017 and 2016.

Revenue

Our revenue increased to $0.8 million for the three months ended June 30, 2017, compared to $19,000 for the three months ended June 30, 2016. This increase was due to a higher number of shipments of Eversense to Rubin and Roche for distribution in Europe during the three months ended June 30, 2017. We made our first shipment of Eversense to Rubin for distribution in Sweden during the three months ended June 30, 2016.

Cost of sales

Our cost of sales increased to $1.7 million for the three months ended June 30, 2017, compared to $34,000 for the three months ended June 30, 2016. This increase was due to increased manufacturing and distribution of Eversense to Roche and Rubin for distribution in Europe during the three months ended June 30, 2017. During the three months ended June 30, 2016, our cost of sales reflected the initial manufacturing and distribution of our first shipment of Eversense to Rubin for distribution in Sweden.

Our gross profit was $(0.9) million and $(15,000) for the three months ended June 30, 2017 and 2016, respectively. Gross profit as a percentage of revenue, or gross margin, changed to (110.6)% in the three months ended June 30, 2017 from (78.9)% in the three months ended June 30, 2016 as a result of manufacturing and distribution efficiencies achieved while ramping up manufacturing to meet product demand in Europe. 

Sales and marketing expenses

Sales and marketing expenses were $1.2 million for the three months ended June 30, 2017, compared to $0.6 million for the three months ended June 30, 2016, an increase of $0.6 million. The $0.6 million increase was primarily

due to a $0.2 million increase in salaries, bonuses and payroll related costs for additional headcount, and a $0.4 million increase in other sales and general marketing expenses to support our European distribution of Eversense.

Research and development expenses

Research and development expenses were $5.6 million for the three months ended June 30, 2017, compared to $7.5 million for the three months ended June 30, 2016, a decrease of $1.9 million. The decrease of $1.9 million was primarily due to a $1.0 million decrease due to the completion of our U.S. pivotal trial in 2016,  and a $0.9 million decrease in expenses related to the development of Eversense.

General and administrative expenses

General and administrative expenses were $3.9 million for the three months ended June 30, 2017, compared to $3.4 million for the three months ended June 30, 2016, an increase of $0.5 million. The increase was primarily due to a $0.3 million increase in recruiting and relocation costs to support hiring efforts, and a $0.2 million increase in information and technology spending for services to support our operations.

Total other expense, net

Total other expense, net, for the three months ended June 30, 2017 and 2016 was $0.7 million and $0.3 million, respectively, consisting primarily of interest expense on our debt facilities.

Comparison of the Six Months Ended June 30, 2017 and 2016

The following table sets forth our results of operations for the six months ended June 30, 2017 and 2016.

Revenue

Our revenue increased to $1.4 million for the six months ended June 30, 2017, compared to $19,000 for the six months ended June 30, 2016. This increase was due to a higher number of shipments of Eversense to Rubin and Roche for distribution in Europe during the six months ended June 30, 2017. We made our first shipment of Eversense to Rubin for distribution in Sweden during the six months ended June 30, 2016.

Cost of sales

Our cost of sales increased to $2.8 million for the six months ended June 30, 2017, compared to $34,000 for the six months ended June 30, 2016. This increase was due to increased manufacturing and distribution of Eversense to Roche and Rubin for distribution in Europe during the three months ended June 30, 2017. During the three months ended June 30, 2016, our cost of sales reflected the initial manufacturing and distribution of our first shipment of Eversense to Rubin for distribution in Sweden.

Our gross profit was $(1.4) million and $(15,000) for the six months ended June 30, 2017 and 2016, respectively. Gross margin changed to (101.8)% in the six months ended June 30, 2017 from (78.9)% in the six months ended June 30, 2016 as a result of manufacturing and distribution efficiencies achieved while ramping up manufacturing to meet product demand in Europe. 

Sales and marketing expenses

Sales and marketing expenses were $2.4 million for the six months ended June 30, 2017, compared to $1.3 million for the six months ended June 30, 2016, an increase of $1.1 million. The $1.1 million increase was primarily due to a $0.5 million increase in salaries, bonuses and payroll related costs for additional headcount, and a $0.6 million increase in other sales and general marketing expenses to support European distribution of Eversense.

Research and development expenses

Research and development expenses were $12.6 million for the six months ended June 30, 2017, compared to $14.0 million for the six months ended June 30, 2016, a decrease of $1.3 million. The decrease of $1.3 million was primarily due to a decrease of $2.3 million in expenses due to the completion of our U.S. pivotal trial in 2016, partially offset by a $1.0 million increase in salaries, bonuses and payroll related costs for additional headcount.

General and administrative expenses

General and administrative expenses were $7.7 million for the six months ended June 30, 2017, compared to $7.2 million for the six months ended June 30, 2016, an increase of $0.5 million. The increase was primarily due to a $1 million increase in recruiting and relocation costs and general spending to support our operations, partially offset by a  $0.5 million decrease in non-cash stock-based compensation expense.

Total other expense, net

Total other expense, net, for the six months ended June 30, 2017 and 2016 was $1.4 million and $0.6 million, respectively, consisting primarily of interest expense on our debt facilities.

Liquidity and Capital Resources

Sources of Liquidity

From our founding in 1996 until 2010, we devoted substantially all of our resources to researching various sensor technologies and platforms. Beginning in 2010, we narrowed our focus to designing, developing and refining a commercially viable glucose monitoring system. However, to date, we have not generated any significant revenue from product sales. We have incurred substantial losses and cumulative negative cash flows from operations since our inception in October 1996. We have never been profitable and our net losses were $12.4 million and $11.9 million for the three months ended June 30, 2017 and 2016, respectively, and $25.4 million and $23.1 million for the six months ended June 30, 2017 and 2016, respectively. As of June 30, 2017, our accumulated deficit totaled $230.2 million.

To date, we have funded our operations principally through the issuance of preferred stock, common stock and debt. As of June  30, 2017, we had cash and cash equivalents and marketable securities of $41.4 million. On March 23, 2016, we effected the initial closing of the March 2016 Offering of our common stock. Additionally, we closed on the partial exercise by the underwriters of the March 2016 Offering on their option to purchase additional shares on April 5, 2016. As a result of these events, we received aggregate net proceeds of $44.8 million. Under the terms of the Amended and Restated Loan and Security Agreement with Oxford and SVB, we may borrow up to an aggregate principal amount

of $30.0 million. Under this debt facility, we initially borrowed an aggregate of $15 million from Oxford and SVB on June 30, 2016. We used $11 million of the $15 million to retire existing loans with Oxford, including a final payment fee of $1 million. In each of November 2016 and March 2017, we borrowed an additional $5 million from Oxford and SVB upon achieving certain milestones. The agreement provides for monthly payments of interest only for a period of 18 months, followed by an amortization period of 30 months. On June 1, 2017, we closed the May 2017 Offering of our common stock and received aggregate net proceeds of $40.4 million.

Our ability to generate revenue and achieve profitability depends on our completion of the development of Eversense and future product candidates and obtaining of necessary regulatory approvals for the manufacture, marketing and sales of those products. These activities, including our planned significant research and development efforts, will require significant uses of working capital through 2017 and beyond. Upon the completion of the audit of our consolidated financial statements for the year ended December 31, 2016, we did not have sufficient cash to fund our operations beyond the third quarter of 2017 without additional financing and, therefore, we concluded there was substantial doubt about our ability to continue as a going concern. As a result, our independent registered public accounting firm included an explanatory paragraph regarding this uncertainty in its report on those consolidated financial statements. The financial information throughout this Quarterly Report and the unaudited consolidated financial statements included elsewhere in this Quarterly Report have been prepared on a basis that assumes that we will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. This financial information and these statements do not include any adjustments that may result from the outcome of this uncertainty.

We expect our existing cash, cash equivalents, and marketable securities available for sale as of June 30, 2017 will enable us to fund our operations into the second quarter of 2018, without receiving additional funding. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. Additionally, the process of clinical and regulatory development of medical devices is costly, and the timing of progress of these efforts is uncertain.

We anticipate that we will continue to incur losses for the foreseeable future. We expect that our research and development expenses and administrative expenses will continue to increase and, as a result, we will need additional capital to fund our operations. Until such time, if ever, as we can generate substantial revenue, we expect to finance our cash needs through a combination of equity offerings, which may include additional follow-on offerings or through an at-the-market facility, debt financings and revenue from potential research and development and other collaboration agreements. To the extent that we raise additional capital through the future sale of equity or debt, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing common stockholders. If we raise additional funds in the future, we may have to relinquish valuable rights to our technologies, future revenue streams or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant licenses to develop and market products that we would otherwise prefer to develop and market ourselves.

Indebtedness

On June 30, 2016, we entered into an Amended and Restated Loan and Security Agreement with the Lenders. Pursuant to the Amended and Restated Loan and Security Agreement, we may potentially borrow up to an aggregate principal amount of $30.0 million in the following four tranches: $15.0 million, or the Tranche 1 Term Loan; $5.0 million, or the Tranche 2 Term Loan; $5.0 million, or the Tranche 3 Term Loan; and $5.0 million, or the Tranche 4 Term Loan. We refer to each of the tranches as a Term Loan, and collectively, the Term Loans. The funding conditions for the Tranche 1 Term Loan were satisfied as of June 30, 2016. Therefore, we issued secured notes to the Lenders for aggregate gross proceeds of $15.0 million, or the Notes, on June 30, 2016. We used approximately $11.0 million from the proceeds from the Notes to repay the outstanding balance under our previously existing Loan and Security Agreement with Oxford, dated as of July 31, 2014, including the applicable final payment fee due thereunder of $1 million. On November 22, 2016, the funding conditions for the Tranche 2 Term Loan were satisfied; therefore we issued secured notes to the Lenders for aggregate gross proceeds of $5.0 million. On March 29, 2017, the funding conditions for the Tranche 3 Term Loan were satisfied; therefore we issued secured notes to the Lenders for aggregate gross proceeds of $5.0 million. We may borrow the Tranche 4 Term Loan on or before December 31, 2017 if we receive PMA approval

from the FDA for Eversense, and achieve trailing six-month revenue for the applicable period of measurement of at least $4.0 million. The maturity date for all Term Loans is June 1, 2020, or the Maturity Date.

The Term Loans bear interest at a floating annual rate of 6.31% plus the greater of (i) 90-day U.S. Dollar LIBOR reported in the Wall Street Journal or (ii) 0.64%, provided that the minimum floor interest rate is 6.95%, and require monthly payments. The monthly payments initially consist of interest-only. After 18 months, the monthly payments will convert to payments of principal and monthly accrued interest, with the principal amount being amortized over the ensuing 30 months.

We may elect to prepay all Term Loans prior to the Maturity Date subject to a prepayment fee equal to 3.00% if the prepayment occurs within one year of the funding date of any Term Loan, 2.00% if the prepayment occurs during the second year following the funding date of any Term Loan, and 1.00% if the prepayment occurs more than two years after the funding date of any Term Loan and prior to the Maturity Date. 

The Amended and Restated Loan and Security Agreement contains customary events of default, including bankruptcy, the failure to make payments when due, the occurrence of a material impairment on the Lenders’ security interest over the collateral, a material adverse change, the occurrence of a default under certain other agreements entered into by us, the rendering of certain types of judgments against us, the revocation of certain of our government approvals, violation of covenants, and incorrectness of representations and warranties in any material respect.  Upon the occurrence of an event of default, subject to specified cure periods, all amounts owed by us would begin to bear interest at a rate that is 5.00% above the rate effective immediately before the event of default, and may be declared immediately due and payable by Lenders.

Pursuant to the Amended and Restated Loan and Security Agreement, we also issued to the Lenders 10‑year stock purchase warrants to purchase an aggregate of 116,581, 63,025 and 80,645 shares of common stock with an exercise price of $3.86, $2.38, and $1.86 per share.

The Notes are collateralized by all of our consolidated assets other than our intellectual property. The Notes also contain certain restrictive covenants that limit our ability to incur additional indebtedness and liens, merge with other companies or consummate certain changes of control, acquire other companies, engage in new lines of business, make certain investments, pay dividends, transfer or dispose of assets, amend certain material agreements or enter into various specified transactions, as well as financial reporting requirements. We incurred issuance costs related to the Notes of approximately $568,648 that are being amortized as additional interest expense over the term of the Notes using the effective interest method. The fair value of the stock purchase warrants, which was estimated to be $526,209, was recorded as a discount to the Notes, which is also being amortized as additional interest expense over the term of the Notes using the effective interest method.

At maturity (or earlier prepayment), we are also required to make a final payment equal to 9.00% of the aggregate principal balances of the funded Term Loans. This fee is being accrued as additional interest expense over the term of the Notes using the effective interest method. In the event that we achieve the requirements to borrow the Tranche 4 Term Loan, and elect not to borrow that tranche, we are obligated to pay the Lenders a non-utilization fee of 2.00% of the undrawn amount.
