Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial statements and related notes in Part II, Item 8 of this Annual Report. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. You should review the “Risk Factors” section of this Annual Report for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

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 Eversense, Eversense XL and Eversense E3 CGM system 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, respectively, as compared to seven to 14 days for non-implantable CGM systems. We affixed the CE mark to

the original Eversense CGM system in June 2016, which marked the first certification for the product to be sold within the European Economic Area (EEA). Subsequently, we affixed the CE mark to the extended life Eversense XL CGM system in September 2017 which is currently available in select markets in Europe and the Middle East. In June 2018, the U.S. Food and Drug Administration, or FDA, approved the Eversense CGM system and it is currently available throughout the United States. In June 2019, we received FDA approval for the non-adjunctive indication (dosing claim) for the 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 extended life Eversense E3 CGM system was approved by the FDA and we expect Ascensia Diabetes Care Holdings AG, or Ascensia, to begin commercializing Eversense E3 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. During 2020, we received positive payor coverage decisions from Cigna Corporation, who has more than 17 million medical customers and offers a Medicare Advantage plan in 17 states and Washington, DC, Blue Cross and Blue Shield plans, and announced local coverage determinations, or LCD, proposals for implantable therapeutic CGMs such as Eversense by all the Medicare Administrative Contractors to enable Eversense to be used by Medicare beneficiaries as a Part B physician service. We continue to see momentum of broad national payor acceptance, including on August 3, 2020, the Center for Medicare and Medicaid Services, or 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 Scheduled that update global payments for the device cost and procedure fees.

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 entered into a 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 Eversense, Eversense XL 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, or 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, or 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 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 6 months in the United States. In September 30, 2019, we completed enrollment of the PROMISE trial. In the trial, we observed performance matching that of the current Eversense 90-day product available in the United States, with a mean absolute relative difference, or 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 Premarket Approval, or 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 and we expect Ascensia Diabetes Care Holdings AG, or Ascensia, to begin commercializing Eversense E3 in the second quarter of 2022.

In March 2019, we launched a patient access program, the Eversense Bridge Program, to assist those patients who do not have insurance coverage for Eversense, or whose insurance is denied or insufficient. Pursuant to this program, we provided financial assistance to eligible patients purchasing Eversense, which may have been substantial depending on a patient’s insurance coverage. We also assisted patients in their appeal of adverse coverage decisions made by insurance providers. In December 2020, we terminated the Eversense Bridge Program. In 2021, Ascensia initiated a patient assistance program to provide financial assistance to patients on Eversense. The lack of a patient assistance program, or a program’s design being ineffective, could adversely impact the sales of Eversense and, consequently our net revenues. In addition, we may not be able to recognize a substantial portion of the revenue related to Eversense insertions for the patients participating in these access programs, or previously the Bridge Program. The amount of time required to obtain favorable coverage and reimbursement decisions, including navigating the appeals process with third-party payors, is uncertain, and we may see increased product utilization without corresponding recognized revenue. Our operating results may be adversely impacted if we are unable to obtain successful appeals or favorable coverage decisions by insurance providers, or if there are not effective patient access programs in place.

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. Following information gathered from this sub-set and continued development efforts, and pending developments at the FDA relating to the ongoing the ongoing COVID-19 pandemic, in the first half of 2022 we plan to seek Investigational Device Exemption, or IDE, from the FDA to explore the 365-day sensor in a clinical trial. If the IDE is approved in a timely manner, we would target to begin enrollment of a clinical trial, in which we intend to include a pediatric population, in the second half of 2022.

On August 9, 2020, we entered into a collaboration and commercialization agreement with Ascensia pursuant to which we granted Ascensia the exclusive right to distribute our 90-day Eversense CGM system and our 180-day Eversense CGM system worldwide for people with diabetes, 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, which are the 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 current distribution agreement with Rubin Medical, which are Sweden, Norway and Denmark; and (iii) until May 31, 2022, the territory does 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, the extended life Eversense E3 CGM system was approved by the FDA and we expect Ascensia to begin commercializing Eversense E3 in the United States in the second quarter of 2022.

European Commercialization of Eversense

In September 2017, we affixed the CE mark to the Eversense XL, which is indicated for a sensor life of up to six months. Eversense XL began commercialization in the EEA 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 Diagnostics International AG and Roche Diabetes Care GmbH, together referred to as 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 December 12, 2019, we further amended the distribution agreement to lower minimum volumes for 2020 and increase pricing for the remaining period of the contract. 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.

COVID-19

On January 30, 2020, the World Health Organization, or the WHO, announced a global health emergency because of a new strain of coronavirus, or COVID-19, and the risks to the international community as the virus spreads globally. On March 11, 2020, the WHO classified the COVID-19 outbreak as a pandemic, based on the rapid increase in exposure globally. In response to the pandemic, many states and jurisdictions have issued stay-at-home orders and other measures aimed at slowing the spread of the coronavirus. The state of Maryland, where we are headquartered, has been affected by COVID-19. The Governor of Maryland issued an order closing all non-essential businesses, which took effect on March 23, 2020. Beginning with the initial outbreak and through 2021 substantially all of our workforce is still working from home either all or substantially all of the time. Additionally, because our sensor requires an in-clinic procedure, we saw a reduction in access to clinics and sensor insertions during multiple periods during the pandemic.

The COVID-19 pandemic infection rates in the United States are still high, vaccine distribution is on-going, and it is difficult to predict the longevity and severity COVID-19 will have on our business.

As a result of the COVID-19 pandemic’s disruption to our operations, suppliers, employees, and the healthcare community in which we sell to and support, and our limited cash resources, in March 2020, we made significant reductions in our cost structure and operations to improve cash flow and generate future expenditure savings to ensure the long-term success of Eversense. Specifically, in the first quarter of 2020, we temporarily suspended commercial sales and marketing of the Eversense CGM System and we reduced our workforce by approximately 60%.

Critical Accounting Estimates

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States.

The preparation of our consolidated financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities and equity and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. These estimates, particularly estimates relating to accounting for variable consideration related to revenue, warranty obligations, inventory obsolescence and embedded derivatives, have a material impact on our financial statements and are discussed in detail throughout our analysis of the results of operations discussed below. We did not make any material changes to these assumptions for the year ended December 31, 2021. We do not expect any material changes in the near term to the underlying assumptions during the year ended December 31, 2022.

We base our estimates on historical experience and various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets, liabilities and equity that are not readily apparent from other sources. Actual results and outcomes could differ from these estimates and assumptions.

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, or collectively, Customers, who then resell the products to health care providers and patients. We are 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. 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 significant 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.

Contract assets consist of trade receivables and unbilled receivables from customers and are recorded at net realizable value. Unbilled receivables relate to the revenue share variable consideration from the Ascensia commercial agreement.

Warranty Obligations

We provide a one-year warranty on our smart transmitters to our customers. We 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 return management authorizations to revenues.

Inventory and Obsolescence

Inventory is valued at the lower of cost or net realizable value. Cost is determined using the standard cost method that approximates first in, first out. We record an adjustment to reduce the value of inventory for items that are potentially obsolete, where the standard costs require adjustment to the net realizable value, and are in excess of future demand taking into consideration the product shelf life. Our sensor manufacturing process can span several months, involves various contract manufacturers and includes raw components with long lead times, often resulting in significant work-in-progress inventory. However, expiry does not commence until the chemistry is applied to the sensor. We are able to isolate pre-chemistry sensor inventory in progress from post-chemistry sensor inventory and finished goods to assess against demand forecasts and customer dating requirements for potential excess or obsolete inventory. Our estimates are based on information known at the time and include factors such as anticipated future usage and sales, potential for external unfavorable conditions such as import holds or quality issues, and planned product upgrades.

However, if actual product quality or conditions differ from our assumptions, additional inventory adjustments that would increase cost of sales could be required.

Derivative Financial Instruments

In connection with our issuance of the convertible senior subordinated notes due 2023, or the 2023 Notes in January 2018, we bifurcated the embedded conversion option, along with the interest make-whole provision and make-whole fundamental change provision, and recorded the embedded conversion option as a derivative liability in our consolidated balance sheets in accordance with ASC Topic 815, Derivatives and Hedging.

In July 2019, we issued $82.0 million in aggregate principal amount of convertible senior subordinated notes due 2025, or the 2025 Notes. In connection with the 2025 Notes, we bifurcated the embedded conversion option along with the fundamental change make-whole provision and the cash settled fundamental make-whole shares provision, and recorded the fair value of these embedded features as a derivative liability in our consolidated balance sheets in accordance with Accounting Standards Codification, or ASC, Topic 815, Derivatives and Hedging.

On April 21, 2020, we entered into the Highbridge Loan Agreement, in which we borrowed an aggregate principal amount of $15.0 million through the issuance and sale of the First Lien Notes and issued 1,500,000 shares of our common stock to the Lenders as a commitment fee. The First Lien Notes also contained redemption features that were evaluated for bifurcation as separate derivative instruments including the permitted prepayment put option, the mandatory accelerated redemption and the mandatory redemption and reinvestment upon an asset sale. We recorded the fair value of the embedded features in the amount of $1.0 million as a debt premium and derivative asset in our consolidated balance sheets in accordance with ASC Topic 815, Derivatives and Hedging. The derivative was adjusted 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 our consolidated statements of operations and comprehensive loss. On August 14, 2020, we prepaid the First Lien Notes in full, including the discounted prepayment premium, in the amount of approximately $17.6 million and recognized a loss on extinguishment in the amount of $0.7 million.

On April 21, 2020, we entered into a Note Purchase and Exchange Agreement with certain funds managed by Highbridge providing for the exchange (the “Exchange”) of $24.0 million aggregate principal amount of our outstanding 2025 Notes for (i) $15.7 million aggregate principal amount of newly issued 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. On August 9, 2020, we entered into a First Amendment to Note Purchase and Exchange Agreement with Highbridge (as amended by the Amendment, the “Exchange Agreement”). The Second Lien Notes also contained redemption features that were evaluated for bifurcation as separate derivative instruments including the permitted prepayment put option, the mandatory accelerated redemption and the mandatory redemption and reinvestment upon an asset sale. Unlike the First Lien Notes, the Second Lien Notes also permit voluntary conversion at the option of the holder as described above. We recorded the fair value of these embedded features in the amount of $1.9 million as a derivative asset in our consolidated balance sheets in accordance with ASC Topic 815, Derivatives and Hedging. 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 our consolidated statement of operations and comprehensive loss. During the fiscal year ended December 31, 2020, Highbridge elected to convert the full $15.7 million of outstanding principal on the Second Lien Notes.

In August 2020, we issued $35.0 million in aggregate principal amount of convertible senior secured notes due 2024, or the PHC Notes. 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. We recorded the fair value of the embedded features as a derivative liability in our consolidated balance sheets in accordance with ASC Topic 815, Derivatives and Hedging.

The derivative instruments are remeasured at the end of each reporting period with changes in fair value recorded in the consolidated statements of operations and comprehensive loss in other income (expense) as a change in fair value of the derivative liability. The fair value assessment incorporates management’s assumptions for probabilities

of conversion occurrence through maturity, stock price, volatility, risky bond rate, and trade data when available. We engage a third-party valuation specialist to perform the valuation using the binomial option pricing model.

Components of Results of Operations

Revenue, net

Our total net revenue increased to $13.7 million for the year ended December 31, 2021, compared to $4.9 million for the year ended December 31, 2020, an increase of $8.7 million. This increase was due to the transition of commercial responsibility for Eversense to Ascensia and its orders for Eversense for distribution in the European Union and in the United States. Ascensia assumed commercial responsibilities for Eversense XL beginning on February 1, 2021 and for the 90-day Eversense product during the second quarter of 2021.

Cost of sales

Our cost of sales decreased to $14.5 million for the year ended December 31, 2021, compared to $22.3 million for the year ended December 31, 2020, a decrease of $7.8 million. The decrease was primarily attributed to the reduction of inventory impairment, write-offs and scrap expense of $13.9 million and a reduction of $0.2 million in salaries &

related costs, partially offset by an increase of $6.3 million in production costs, freight and logistic cost and warranty and replacement costs related to the commercialization of Eversense under the Ascensia commercialization and collaboration agreement.

Gross profit (loss) was $(0.8) million and $(17.4) million for the years ended December 31, 2021 and 2020, respectively. Gross profit as a percentage of revenue, or gross margin, was (5.9)% and (350.9)% for the years ended December 31, 2021 and 2020, respectively. The improved gross margin was primarily due to the fulfillment of orders utilizing existing written off inventory as a result of the COVID-19 pandemic.

Sales and marketing expenses

Sales and marketing expenses were $7.6 million for the year ended December 31, 2021, compared to $20.6 million for the year ended December 31, 2020, a decrease of $12.9 million. The decrease was primarily the result of the reduction in sales support due to the transition to Ascensia for the commercialization of Eversense.

Research and development expenses

Research and development expenses were $27.2 million for the year ended December 31, 2021, compared to $20.4 million for the year ended December 31, 2020, an increase of $6.8 million. The increase was due to the expansion of our R&D workforce which was $2.2 million increase in personnel-related costs. Also, the increase was due to various R&D efforts to improve our sensor & transmitter technology in 2021 that led to $4.1 million increase in consulting, contract fabrication and other R&D support services and an increase of $0.5 million in clinical studies.

General and administrative expenses

General and administrative expenses were $21.5 million for the year ended December 31, 2021, compared to $20.8 million for the year ended December 31, 2020, an increase of $0.7 million. The increase was due to higher salaries and related expenses of $1.3 million, primarily related to stock-based compensation and related expenses, offset by a reduction of $0.6 million in other administrative expenses including accounting and consulting costs.

Total other income (expense), net

Total other income (expense), net, was ($245.3) million for the year ended December 31, 2021, compared to ($96.0) million for the year ended December 31, 2020, an increase of $149.3 million expense. The increase in expense was primarily due to a $162.5 million change in fair value of the embedded derivatives in our convertible notes, $22.4 million change in non-cash loss on fair value adjustment of the Energy Capital Option and an increase of $0.6 million in interest expense, offset by a $21.4 million reduction in loss on extinguishment of debt, a $12.7 million reduction in loss on issuance of debt & issuance costs, a reduction of $1.2 million in debt issuance cost a decrease of $0.7 million in impairment cost, a decrease of $0.1 million in other expenses and a $0.1 million increase in interest income.

Comparison of the Years Ended December 31, 2020 and 2019

For the discussion of our financial condition and results of operations for the year ended December 31, 2020 compared to the year ended December 31, 2019, please refer to Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on March 5, 2021.

Liquidity and Capital Resources

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 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 $302.5 million, $175.2 million, and $115.5 million for the years ended December 31, 2021, 2020 and 2019, respectively. As of December 31, 2021, we had an accumulated deficit of $951.0 million. To date, we have funded our operations principally through the issuance of preferred stock, common stock, convertible note issuance and debt. As of December 31, 2021, we had cash, cash equivalents and marketable securities of $181.8 million.

In November 2021, we entered into an Open Market Sale Agreement, or 2021 Sales Agreement, with Jefferies LLC, or 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. As of the date of this Annual Report on Form 10-K, we have received $8.1 million in net proceeds from the sale of 3,077,493 shares of our common stock under the 2021 Sales Agreement.

In November 2019, we entered into an Open Market Sale Agreement, or 2019 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 $50.0 million through Jefferies as our sales agent in an “at the market” offering. In June 2021, we received $48.4 million in net proceeds from the sale of 12,830,333 shares of our common stock utilizing the full capacity under the 2019 Sales Agreement. For the twelve months ended December 31, 2020, we had received $0.1 million in net proceeds from the sale of 175,289 shares of our common stock under the 2019 Sales Agreement.

On January 21, 2021, we entered into an underwriting agreement, which was subsequently amended and restated on the same day, or the Underwriting Agreement, with H.C. Wainwright & Co., LLC, as representative of the underwriters, the Underwriters, to issue and sell 51,948,052 shares of common stock, in an underwritten public offering pursuant to effective registration statements on Form S-3, including and a related prospectus and prospectus supplement, in each case filed with the Securities and Exchange Commission, the Offering. The price to the public in the Offering was $1.925 per share of common stock. The Underwriters agreed to purchase the shares from the Company pursuant to the Underwriting Agreement at a price of $1.799875 per share and the Company also agreed to reimburse them for customary fees and expenses. The initial closing of the Offering occurred on January 26, 2021. Subsequent to the initial closing, the Underwriters exercised their option to purchase an additional 7,792,207 shares of Common Stock. Total net proceeds from the Offering were $106.1 million after deducting underwriting discounts and commissions and estimated offering expenses.

On January 17, 2021, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain institutional purchasers, the Purchasers, pursuant to which we sold to the Purchasers, in a registered direct offering, the Registered Direct Offering, an aggregate of 40,000,000 shares, the Shares, of common stock, $0.001 par value per share. The Shares were sold at a purchase price of $1.25 per share for aggregate gross proceeds to the us of $50 million, before deducting fees to the placement agent and other estimated offering expenses payables. The Shares were offered and sold by us pursuant to an effective shelf registration statement on Form S-3, which was originally filed with the Securities and Exchange Commission on November 27, 2019. The net proceeds to us from the Registered Direct Offering, after deducting fees and expenses and the estimated offering expenses payable by us, are approximately $46.1 million.

On November 9, 2020, we entered into an equity line agreement, the Equity Line Agreement, with Energy Capital, LLC, or 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 our newly designated series B convertible preferred stock, or the Series B Preferred Stock, at our 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 we have less than $8 million of cash, cash equivalents and other available credit (aside from availability under the Equity Line Agreement), we have the right, in our sole discretion, to present Energy Capital with a purchase notice, or 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 our Series B Preferred Stock at a per share price, or 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 nine months after the date of its issuance, at a conversion price of

$0.3951 per share. The Equity Line Agreement provides that we shall not affect any Regular Purchase under the Equity Line Agreement on any date where the closing price of the common stock on the NYSE American is less than $0.25 without the approval of Energy Capital.

On August 9, 2020, we entered into a financing agreement with Ascensia’s parent company, PHC, pursuant to which we issued $35.0 million in aggregate principal amount 2024 Notes, to PHC. We also issued PHC 2,941,176 shares of common stock to PHC as a financing fee. We also have 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 approval for the 180-day Eversense product for marketing in the United States before such date. Upon the closing of the 2024 Notes, we prepaid the First Lien Notes in full in the amount of approximately $17.6 million, which includes the discounted prepayment premium.

Additionally, on August 9, 2020, we entered into a Stock Purchase Agreement with Masters Special Solutions, LLC and certain affiliates thereof, or Masters, pursuant to which we issued and sold to Masters 3,000 shares of convertible preferred stock, designated as Series A Preferred Stock, the Series A Preferred Stock, at a price of $1,000.00 per share in an initial closing. Masters also had the option to purchase up to an additional 27,000 shares of Series A Preferred Stock at a price of $1,000.00 per share in subsequent closings, subject to the terms and conditions of the Stock Purchase Agreement, as amended, through January 11, 2021. In January 2021, Masters and its assignees purchased in aggregate an additional 22,783 shares of Series A Preferred Stock, resulting in additional gross proceeds of $22.8 million. Each share of Series A Preferred Stock is initially convertible into a number of shares of common stock equal to $1,000 divided by the conversion price of $0.476 per share, subject to customary anti-dilution adjustments, including in the event of any stock split. All shares of Series A Preferred Stock have been converted to common stock as of December 31, 2021.

Warrants

On July 16, 2019, we issued Solar warrants to purchase an aggregate of 1,125,000 shares of the Company’s common stock with an exercise price of $1.20 per share, or the Solar Warrants. The Solar Warrants are exercisable until July 25, 2029. As of December 31, 2021, the Solar Warrants have been exercised in full, on a net basis.

On November 9, 2020, we issued Energy Capital warrants to purchase up to 10,000,000 shares of Company’s common stock with an exercise price of $0.3951 per share, or the Energy Capital Warrants. The Energy Capital Warrants have a vesting date of May 9, 2021. The Warrants can be exercised, in either a cashless exercise or a cash basis, at any time after the vesting date but prior to November 9, 2030. Energy Capital may exercise the Warrants at any time after the vesting date, without contingencies and independently of whether any shares of Series B preferred stock are issued.

Indebtedness

Term Loans

On July 16, 2019, we entered into a Loan and Security Agreement, or the Solar Loan Agreement, with Solar Capital, Ltd., or Solar. Pursuant to the Solar Loan Agreement, on July 25, 2019, or the effective date, we borrowed the Solar Term Loan in an aggregate principal amount of $45.0 million, or the Solar Term Loan. We used $11.6 million of the Solar Term Loan to repay in full the term loans, or the Oxford/SVB Term Loans and together with the Solar Term Loan, the Term Loans, borrowed pursuant to our Amended and Restated Loan and Security Agreement with Oxford Finance LLC, or Oxford, and Silicon Valley Bank, or SVB.

On March 22, 2020 we terminated our Loan and Security Agreement with Solar and repaid the $45.0 million principal balance in full.

PPP Loan

On April 22, 2020, we 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 SBA. The unsecured loan, or the PPP Loan, is evidenced by the

PPP Note dated April 21, 2020, or the PPP Note, in the principal amount of $5.8 million with Silicon Valley Bank, or the Bank.

Under the terms of the PPP Note and the PPP Loan, interest accrues on the outstanding principal at a rate of 1.0% per annum. We have elected not to apply for forgiveness and are making monthly payments of principal and interest until the loan is paid in full in the second quarter of 2022. The term of the PPP Note is two years, though it may be payable sooner in connection with an event of default under the PPP Note.

The PPP Note may be prepaid in part or in full, at any time, without penalty. The PPP Note provides for certain customary events of default, including (i) failing to make a payment when due under the PPP Note, (ii) failure to do anything required by the PPP Note or any other loan document, (iii) defaults of any other loan with the Bank, (iv) failure to disclose any material fact or make a materially false or misleading representation to the Bank or SBA, (v) default on any loan or agreement with another creditor, if the Bank believes the default may materially affect our ability to pay the PPP Note, (vi) failure to pay any taxes when due, (vii) becoming the subject of a proceeding under any bankruptcy or insolvency law, having a receiver or liquidator appointed for any part of our business or property, or making an assignment for the benefit of creditors, (viii) having any adverse change in financial condition or business operation that the Bank believes may materially affect our ability to pay the PPP Note, (ix) if we reorganize, merge, consolidate, or otherwise change ownership or business structure without the Bank’s prior written consent, or (x) becoming the subject of a civil or criminal action that the Bank believes may materially affect our ability to pay the PPP Note. Upon the occurrence of an event of default, the Bank has customary remedies and may, among other things, require immediate payment of all amounts owed under the PPP Note, collect all amounts owing from us, and file suit and obtain judgment against us.

Highbridge Loan Agreement

On April 21, 2020, we entered into the Highbridge Loan Agreement, with certain funds managed by Highbridge Capital Management, LLC, or Highbridge, as the lenders (together with the other lenders from time to time party thereto, or the Lenders) and Wilmington Savings Fund Society, SCB, as collateral agent.

Pursuant to the Highbridge Loan Agreement, we borrowed an aggregate principal amount of $15.0 million on April 24, 2020 through the issuance and sale of First Lien Notes. In connection with the Highbridge Loan Agreement and receipt of the first tranche of borrowing, we issued 1,500,000 shares of our common stock to the Lenders as a commitment fee.

Upon the closing of the PHC Notes, we prepaid the First Lien Notes in full in the amount of approximately $17.6 million, which includes the discounted prepayment premium.

Exchange Agreement with Highbridge

On April 21, 2020 we entered into a Note Purchase and Exchange Agreement, or the Exchange Agreement, which we subsequently amended on August 9, 2020, with certain funds managed by Highbridge providing for the exchange of $24.0 million aggregate principal amount of our outstanding senior convertible notes due January 15, 2025, or the 2025 Notes, for (i) $15.7 million aggregate principal amount of newly issued Second Lien Secured Notes, or the Second Lien Notes, (ii) 11,026,086 shares of our common stock, (iii) warrants to purchase up to 4,500,000 shares of our 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. The exchange closed on April 24, 2020. The warrants may be exercised for cash or on a cashless basis at any time through the three year anniversary of the issuance date.

As amended by the Amendment, effective as of the Closing Date, the holders of the Second Lien Notes had the right to convert the aggregate principal of the Second Lien Notes (together with any applicable prepayment premium) to common stock at a price per share equal to 90% of the greater of (i) the daily volume weighted average of the price per share of the common stock, on the conversion date, or if the conversion date is not a trading date, the trading day immediately prior to the conversion date and (ii) $0.33 per share. This conversion option had a daily limit of $1,000,000 in aggregate converted principal (inclusive of principal amount of First Lien Notes that were voluntarily converted).

During the fiscal year ended December 31, 2020, Highbridge elected to convert the full $15.7 million of outstanding principal on the Second Lien Notes for issuance of 42,776,936 shares of common stock, which included prepayment premiums and were based off of our election of PIK interest.

Funding Requirements and Outlook

Our ability to generate revenue 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, certifications 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 in the United States, will require significant uses of working capital through 2022 and beyond.

Management has concluded that based on our current operating plans, existing cash and cash equivalents and cash flows from our future operations will be sufficient to meet our anticipated operating needs through 2023. As part of our liquidity strategy, we will continue to monitor our capital structure and operating plans and we may access the capital markets or debt 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.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

The market risk inherent in our financial instruments and in our financial position represents the potential loss arising from adverse changes in interest rates. As of December 31, 2021, we had cash, cash equivalents and marketable securities of $181.8 million and at December 31, 2020 we had cash, cash equivalents and restricted cash of $18.2 million. We generally hold our cash in interest-bearing money market accounts or short-term investments that meet our policy for cash equivalents. Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates. Due to the short-term maturities of our cash equivalents and the low risk profile of our investments, an immediate 100 basis point change in interest rates would not have a material effect on the fair market value of our cash equivalents. The interest rate on all of our notes payable are fixed. We do not currently engage in hedging transactions to manage our exposure to interest rate risk.

Foreign Currency Risk

The majority of our international sales are denominated in Euros. Therefore, our U.S. dollar value of sales is impacted by exchange rates versus the Euro. Currency fluctuations or a strengthening U.S. dollar can decrease our revenue from these Euro-denominated international sales. To date, foreign currency transaction gains and losses and exchange rate fluctuations have not been material to our consolidated financial statements, and we do not believe that the effect of a hypothetical 10% change in foreign currency exchange rates applicable to our business would have had a

material impact on our operating results or financial condition. We do not currently engage in any hedging transactions to manage our exposure to foreign currency exchange rate risk.

In addition, the uncertainty that exists with respect to the economic impact of the global COVID-19 pandemic has introduced significant volatility in the financial markets subsequent to our quarter ended December 31, 2021, which could increase our foreign currency and interest rate risk.

Notes to Consolidated Financial Statements

1. Organization

Senseonics Holdings, Inc., a Delaware corporation, is a medical technology company focused on the development and manufacturing of long-term, implantable continuous glucose monitoring system 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 and was originally incorporated on October 30, 1996 and commenced operations on January 15, 1997. Senseonics Holdings and Senseonics, Incorporated are hereinafter collectively referred to as the “Company” unless otherwise indicated or the context otherwise requires.

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 suffered substantial operating losses, principally from expenses associated with the Company’s research and development programs and commercial launch of the Eversense® CGM System (for use up to 90 days) in the United States and the Eversense CGM and Eversense XL CGM Systems (for use up to six months) in Europe, the Middle East, and Africa. The Company has not generated significant revenue from the sale of products and its ability to generate revenue and achieve profitability largely depends on the Company’s ability to successfully expand the commercialization of Eversense, continue the development of its products and product upgrades, and to obtain necessary regulatory approvals or certifications for the sale of those products. These activities will require significant uses of working capital through 2022 and beyond.

The Company generated a net loss of $302.5 million for the twelve months ended December 31, 2021 and had an accumulated deficit of $951.0 million at December 31, 2021. To date, we have funded its operations principally through the issuance of preferred stock, common stock, convertible note issuance and debt. As of December 31, 2021, we had cash, cash equivalents and marketable securities of $181.8 million

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 the 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. For the twelve months ending December 31, 2021, the Company did not execute any sales of common stock under the 2021 Sales Agreement. However, as of the date of this Annual Report on Form 10-K, the Company received $8.1 million in net proceeds from the sale of 3,077,493 shares of its common stock under the 2021 Sales Agreement.

In November 2019, the Company entered into an Open Market Sale Agreement (the “2019 Sales Agreement”) with 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 $50.0 million through Jefferies as the sales agent in an “at the market” offering. In June 2021, the Company received $48.4 million in net proceeds from the sale of 12,830,333 shares of its common stock utilizing the full capacity under the 2019 Sales Agreement. For the twelve months ended December 31, 2020, the Company received $0.1 million in net proceeds from the sale of 175,289 shares of its common stock under the 2019 Sales Agreement.

On January 21, 2021, the Company entered into an underwriting agreement, which was subsequently amended and restated on the same day (the “Underwriting Agreement”) with H.C. Wainwright & Co., LLC, as representative of the underwriters (the “Underwriters”), to issue and sell 51,948,052 shares of common stock, in an underwritten public offering pursuant to effective registration statements on Form S-3, including and a related prospectus and prospectus supplement, in each case filed with the Securities and Exchange Commission (the “Offering”). The price to the public in the Offering was $1.925 per share of common stock. The Underwriters agreed to purchase the shares from the Company

pursuant to the Underwriting Agreement at a price of $1.799875 per share and the Company also agreed to reimburse them for customary fees and expenses. The initial closing of the Offering occurred on January 26, 2021. Subsequent to the initial closing, the Underwriters exercised their option to purchase an additional 7,792,207 shares of Common Stock. Total net proceeds from the Offering were $106.1 million after deducting underwriting discounts and commissions and estimated offering expenses.

On January 17, 2021, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain institutional purchasers (the “Purchasers”), pursuant to which the Company sold to the Purchasers, in a registered direct offering (the “Registered Direct Offering”), an aggregate of 40,000,000 shares (the “Shares”) of common stock, $0.001 par value per share. The Shares were sold at a purchase price of $1.25 per share for aggregate gross proceeds to the Company of $50 million, before deducting fees to the placement agent and other estimated offering expenses payable by the Company. The Shares were offered and sold by the Company pursuant to an effective shelf registration statement on Form S-3, which was originally filed with the Securities and Exchange Commission on November 27, 2019.

3. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements reflect the accounts of Senseonics Holdings and its wholly owned subsidiary Senseonics. All intercompany balances and transactions have been eliminated in consolidation.

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 consolidated financial statements, estimates are used for, but not limited to, stock-based compensation, recoverability of long-lived assets, deferred taxes and valuation allowances, derivative assets and liabilities, obsolete inventory, warranty obligations, variable consideration related to revenue, 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.

Segment Information

The Company views its operations and manages its business in one segment, glucose monitoring products.

Comprehensive Loss

Comprehensive income (loss) comprises net income (loss) and other changes in equity that are excluded from net income (loss). For the twelve months ended December 31, 2021, the Company’s comprehensive income (loss) included $0.2 million of other comprehensive loss related to the unrealized loss on marketable securities. For the years ended December 31, 2020 and 2019, the Company’s net loss equaled its comprehensive loss and, accordingly, no additional disclosure is presented.

Cash and Cash Equivalents and Concentration of Credit Risk

The Company considers highly liquid investments with original 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. Cash, cash equivalents and restricted cash consisted of the following (in thousands):

Concentration of Revenues and Customers

Net revenue from the Company’s distribution arrangement with Ascensia, a related party, accounted for 90% of total net revenues for the year ended December 31, 2021. Net revenue from distribution arrangement with Roche Diabetes Care GmbH, a related party, accounted for 72% of total net revenues for the year ended December 31, 2020. Revenue from distribution arrangement with Edwards Healthcare Centers, Advanced Diabetes Supply, and Solara Medical Supply, strategic fulfillment partners and supplier of CGM systems to diabetic patients in the United States, accounted for 19%, 15%, and 10%, respectively, of total net revenues for the year ended December 31, 2020. During the year ended December 2019, the Company derived 77% of its total net revenue from Roche, and 12% from Advanced Diabetes Supply.

Marketable Securities

Marketable securities consist of commercial paper, corporate debt securities, asset backed securities and government and agency 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. We classify all available-for-sale marketable securities with maturities greater than one year from the balance sheet date as non-current assets. We do not generally intend to sell these investments and it is not more likely than not that we will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity.

Inventory and Obsolescence

Inventory is valued at the lower of cost or net realizable value. Cost is determined using the standard cost method that approximates first in, first out. The Company records an adjustment to reduce the value of inventory for items that are potentially obsolete, where standard costs require adjustment to the net realizable value, and are in excess of future demand taking into consideration the product shelf life. The sensor manufacturing process can span several months, involves various contract manufacturers and includes raw components with long lead times, often resulting in significant work-in-progress inventory. However, expiry does not commence until the chemistry is applied to the sensor. The Company is able to isolate pre-chemistry sensor inventory in progress from post-chemistry sensor inventory in progress and finished goods to assess against demand forecasts and customer dating requirements for potential excess or obsolete inventory. The Company’s estimates are based on information known as of the balance sheet date and include factors such as anticipated future usage and sales, potential for external unfavorable conditions such as import holds or quality issues, and planned product upgrades. However, if actual product quality or conditions differ from the Company’s assumptions, additional inventory adjustments that would increase cost of sales could be required.

Accounts Receivable

The Company grants credit to various customers in the normal course of business. Accounts receivable consist of amounts due from distributors and are reduced by 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. The Company does not have a history of collectability concerns, and no allowance for uncollectible accounts was recorded as of December 31, 2021. The Company had an immaterial allowance for doubtful accounts as of December 31, 2020.

Property and Equipment

Property and equipment are stated at cost and depreciated using the straight-line method over the estimated useful lives of the assets, which is generally between three to seven years, and is recorded within operating expenses and cost of goods sold in the consolidated statements of operations and comprehensive loss. 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 statement of operations.

Long-lived Assets

Management reviews long-lived assets, including property and equipment and right-of-use assets 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 identified indicators of impairment on right-of-use assets in 2021. Management did not identify any indicators of impairment in 2020 and 2019.

Derivative Financial Instruments

In connection with the Company’s issuance of the convertible senior subordinated notes due 2023 (the “2023 Notes”), in January 2018, the Company bifurcated the embedded conversion option, along with the interest make-whole

provision and make-whole fundamental change provision, and recorded the embedded conversion option as a derivative liability in the Company’s consolidated balance sheets in accordance with Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging.

In July 2019, the Company issued $82.0 million in aggregate principal amount of convertible senior subordinated notes due 2025 (the “2025 Notes). In connection with the 2025 Notes, the Company bifurcated the embedded conversion option along with the fundamental change make-whole provision and the cash settled fundamental make-whole shares provision, and recorded the fair value of these embedded features as a derivative liability in the Company’s consolidated balance sheets in accordance with ASC Topic 815, Derivatives and Hedging.

On April 21, 2020, the Company entered into the Highbridge Loan Agreement, in which an aggregate principal amount of $15.0 million was borrowed through the issuance and sale of the First Lien Notes and issued 1,500,000 shares of its common stock to the Lenders as a commitment fee. The First Lien Notes also contained redemption features that were evaluated for bifurcation as separate derivative instruments including the permitted prepayment put option, the mandatory accelerated redemption and the mandatory redemption and reinvestment upon an asset sale. The Company recorded the fair value of the embedded features in the amount of $1.0 million as a debt premium and derivative asset in its consolidated balance sheets in accordance with ASC Topic 815, Derivatives and Hedging. The derivative was adjusted 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 its consolidated statements of operations and comprehensive loss. On August 14, 2020, the Company prepaid the First Lien Notes in full, including the discounted prepayment premium, in the amount of approximately $17.6 million and recognized a loss on extinguishment in the amount of $0.7 million.

On April 21, 2020, the Company entered into a Note Purchase and Exchange Agreement with certain funds managed by Highbridge providing for the exchange (the “Exchange”) of $24.0 million aggregate principal amount of the outstanding 2025 Notes for (i) $15.7 million aggregate principal amount of newly issued 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. On August 9, 2020, the Company entered into a First Amendment to Note Purchase and Exchange Agreement with Highbridge (as amended by the Amendment, the “Exchange Agreement”). The Second Lien Notes also contained redemption features that were evaluated for bifurcation as separate derivative instruments including the permitted prepayment put option, the mandatory accelerated redemption and the mandatory redemption and reinvestment upon an asset sale. Unlike the First Lien Notes, the Second Lien Notes also permit voluntary conversion at the option of the holder as described above. The Company recorded the fair value of these embedded features in the amount of $1.9 million as a derivative asset in its consolidated balance sheets in accordance with ASC Topic 815, Derivatives and Hedging. 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 its consolidated statement of operations and comprehensive loss. During the fiscal year ended December 31, 2020, Highbridge elected to convert the full $15.7 million of outstanding principal on the Second Lien Notes for issuance of 42,776,936 shares of common stock, which included prepayment premiums and were based off of its election of PIK interest.

In August 2020, the Company issued $35.0 million in aggregate principal amount of convertible senior secured notes due PHC, or the PHC Notes. 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 Topic 815, Derivatives and Hedging.

The financial instruments above are remeasured at the end of each reporting period with changes in fair value recorded in the consolidated statements of operations and comprehensive loss in other income (expense) as a change in fair value of the derivative liability.

Warranty Obligation

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 return management authorizations to revenue.

At December 31, 2021 and December 31, 2020, the warranty reserve was $0.7 million and $0.6 million, respectively. The following table provides a reconciliation of the change in estimated warranty liabilities for the years ended December 31, 2021 and 2020 (in thousands):

December 31, December 31,

Balance at beginning of the period $ 646 $ 2,197
