Notes to Condensed Financial Statements

1. Organization

Organization, Nature of Business

Avinger, Inc. (the “Company”), a Delaware corporation, was incorporated in March 2007. The Company designs, manufactures and sells image-guided, catheter-based systems that are used by physicians to treat patients with peripheral artery disease (“PAD”). Patients with PAD have a build-up of plaque in the arteries that supply blood to areas away from the heart, particularly the pelvis and legs. The Company manufactures and sells a suite of products in the United States (“U.S.”) and in select international markets. The Company has developed its Lumivascular platform, which integrates optical coherence tomography ( “OCT”) visualization with interventional catheters and is the industry’s only system that provides real-time intravascular imaging during the treatment portion of PAD procedures. The Company’s Lumivascular platform consists of a capital component, our Lightbox consoles, as well as a variety of disposable catheter products. The Company’s current catheter products include Ocelot and Tigereye, which are designed to allow physicians to penetrate a total blockage in an artery, known as a chronic total occlusion (“CTO”). The Company also has image-guided atherectomy products, Pantheris and Pantheris SV, which are designed to allow physicians to precisely remove arterial plaque in PAD patients. The Company is in the process of developing next-generation CTO crossing devices to target coronary CTO markets. The Company is located in Redwood City, California.

Liquidity Matters

In the course of its activities, the Company has incurred losses and negative cash flows from operations since its inception. As of March 31, 2022, the Company had an accumulated deficit of $389.9 million. The Company expects to incur losses for the foreseeable future. The Company believes that its cash and cash equivalents of $20.0 million at March 31, 2022 and expected revenues and funds from operations will be sufficient to allow the Company to fund its current operations into the second quarter of 2023. The Company received net proceeds of approximately $6.7 million net proceeds from the  January 2022 Series D preferred stock equity financing and $13.0 million from the sale of its common stock in February 2021. The Company may decide to raise additional funds in future equity offerings to meet its operational needs and capital requirements for product development, clinical trials and commercialization or other strategic objectives.

The Company can provide no assurance that it will be successful in raising funds pursuant to additional equity or debt financings or that such funds will be raised at prices that do not create substantial dilution for its existing stockholders. Given the volatility in the Company’s stock price, any financing that the Company may undertake in the next twelve months could cause substantial dilution to its existing stockholders, and there can be no assurance that the Company will be successful in acquiring additional funding at levels sufficient to fund its various endeavors. In addition, the COVID-19 pandemic and responses thereto have resulted in reduced consumer and investor confidence, instability in the credit and financial markets, volatile corporate profits, restrictions on elective medical procedures, and reduced business and consumer spending, which could increase the cost of capital and/or limit the availability of capital to the Company.

If the Company is unable to raise additional capital in sufficient amounts or on terms acceptable to it, the Company may have to significantly reduce its operations or delay, scale back or discontinue the development and sale of one or more of its products. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. The Company’s ultimate success will largely depend on its continued development of innovative medical technologies, its ability to successfully commercialize its products and its ability to raise significant additional funding.

On September 22, 2021, the Company received a letter from Nasdaq’s Listing Qualifications Department notifying it that it was not in compliance with Nasdaq Listing Rule 5550(a)(2), as the minimum bid price for its listed securities was less than $1 for the previous 30 consecutive business days. The Company had a period of 180 calendar days, or until March 21, 2022, to regain compliance with the rule referred to in this paragraph. The Company did not regain compliance with the minimum bid price requirement by March 21, 2022. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company provided written notice to Nasdaq of its intent to cure the deficiency and, on March 22, 2022, the Company received notice that Nasdaq granted the Company an additional 180 calendar days, or until September 19, 2022, to regain compliance.

On March 29, 2022, the Company received a letter from Nasdaq notifying the Company that the Staff had determined that the closing bid price of the Company’s common stock had been at $1.00 per share or greater for at least 10 consecutive business days and, accordingly, that the Company had regained compliance with the minimum bid price requirement for continued listing on the Nasdaq Stock Market and that the matter is now closed. While the Company has regained compliance with the minimum bid price requirement, there can be no assurance that the Company will be able to maintain compliance with the minimum bid price requirement in the future.

Public Offerings

Past Offerings

On February 2, 2021, under the shelf registration statement, the Company completed a bought deal offering of 500,000 shares of common stock at an offering price of $28.80 per share. As a result, the Company received aggregate net proceeds of approximately $13.0 million after underwriting discounts, commissions, legal and accounting fees, and other ancillary expenses.

January 2022 Offering

On January 14, 2022, the Company entered into a securities purchase agreement with several institutional investors pursuant to which the Company agreed to sell and issue, in a registered direct offering ( “January 2022 Offering”), an aggregate of 7,600 shares of the Company’s Series D Convertible Preferred Stock, par value of $0.001 per share, at an offering price of $1,000 per share which is convertible into common stock at a conversion price of $8.00 per share. Concurrently, the Company agreed to issue to these investors warrants to purchase up to an aggregate of 807,500 shares of the Company’s common stock (the “Common Warrants”). As a result, the Company received aggregate net proceeds of approximately $6.7 million after underwriting discounts, commissions, legal and accounting fees, and other ancillary expenses.

In connection with the January 2022 Offering and in accordance with the securities purchase agreement, the Company held a special meeting of stockholders on March 11, 2022 to consider a proposal (the “Proposal”) to amend the Company’s Amended and Restated Certificate of Incorporation, as amended (the “Charter”) to effect a reverse split of the outstanding shares of the Company’s common stock at a ratio between 1-for-5 and 1-for-20 (the “Reverse Split Amendment”). The Company’s stockholders approved the Reverse Split Amendment at the special meeting. On March 11, 2022, following receipt of stockholder approval, the Company’s Board of Directors approved a reverse split ratio of 1-for-20 and the Company filed an amendment to the Company’s Charter to effect such reverse stock split, effective as of 5:00 pm Eastern Time on March 14, 2022.

Pursuant to the purchase agreement, the Company filed a certificate of designation (the “Certificate of Designation”) with the Secretary of State of Delaware designating the rights, preferences and limitations of the shares of Series D preferred stock, which became effective on January 14, 2022. The Certificate of Designation provided, in particular, that the Series D preferred stock will have no voting rights, other than the right to vote as a class on certain matters, except that each share of Series D preferred stock had the right to cast 37,500 votes per share of Series D preferred stock on the Proposal (the “Supermajority Voting Rights”); provided, that the votes cast by the holders of the Series D preferred stock must be counted in the same proportion as the aggregate shares of common stock voted on the Proposal. Because the Proposal was approved by our stockholders at the special meeting held on March 11, 2022, the Series D preferred stock no longer has Supermajority Voting Rights.

The holders of the Series D preferred stock are entitled to dividends, on an as-if converted basis, equal to dividends actually paid, if any, on shares of Common Stock. The Series D preferred stock is convertible into shares of common stock at a conversion price of $8.00 per share, as adjusted for the most recent reverse stock split. The conversion price can be adjusted pursuant to the Certificate of Designation for stock dividends and stock splits, subsequent rights offerings, pro rata distributions of dividends or the occurrence of a fundamental transaction (as defined in the Certificate of Designation). The Series D preferred stock can be converted at the option of the holders at any time. In addition, subject to the satisfaction of certain conditions, the Company may cause the holders of the Series D preferred stock to convert their shares of Series D preferred stock; provided, that shares of Series D preferred stock cannot be converted to common stock if the applicable holder would beneficially own in excess of 4.99% (or, upon election by such holder prior to the issuance of any shares of Series D preferred stock, 9.99%) of our outstanding common stock. A holder of Series D preferred stock may, upon notice to the Company, increase or decrease such beneficial ownership limitation, but not in excess of 9.99%.

The 807,500 Common Warrants have an exercise price of $9.60 per share and become exercisable beginning July 14, 2022. The Common Warrants will expire five years following the time they become exercisable, or July 14, 2027. The Company also issued to the Placement Agent or its designees warrants to purchase up to an aggregate of 66,500 shares of common stock (the “Placement Agent Warrants”). The Placement Agent Warrants are subject to the same terms as the Common Warrants, except that the Placement Agent Warrants have an exercise price of $10.00 per share and a term of five years from the commencement of the sales pursuant to the January 2022 Offering, or January 12, 2027.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC (“SEC”). The accompanying unaudited condensed interim financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the Company’s financial information. The results for the three months ended March 31, 2022 are not necessarily indicative of results to be expected for the year ending December 31, 2022, or for any other interim period or for any future year. The December 31, 2021 condensed balance sheet data has been derived from audited financial statements. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to SEC rules and regulations relating to interim financial statements. These unaudited condensed financial statements and notes should be read in conjunction with the financial statements included in the Company’s Form 10-K for the fiscal year ended December 31, 2021, which was filed with the SEC on March 22, 2022. The Company’s significant accounting policies are more fully described in Note 2 of the Notes to Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

On March 11, 2022, the Company’s Board of Directors approved an amendment to the Company’s amended and restated certificate of incorporation to effect a 1-for-20 reverse stock split of the Company’s issued and outstanding common stock. The reverse stock split became effective on March 14, 2022. The par value of the common stock was not adjusted as a result of the reverse stock split. All common stock, stock options, restricted stock units, and per share amounts in the financial statements have been retroactively adjusted for all periods presented to give effect to the reverse stock split.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts and disclosures reported in the financial statements. Management uses significant judgment when making estimates related to its stock-based compensation, accruals related to compensation, the valuation of the common stock warrants, provisions for doubtful accounts receivable and excess and obsolete inventories, clinical trial accruals, and its reserves for sales returns and warranty costs. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, actual results may ultimately materially differ from these estimates and assumptions.

Concentration of Credit Risk, and Other Risks and Uncertainties

Financial instruments that potentially subject the Company to credit risk consist of cash and cash equivalents and accounts receivable to the extent of the amounts recorded on the balance sheets.

The Company’s policy is to invest in cash and cash equivalents, consisting of money market funds. These financial instruments are held in Company accounts at one financial institution. The counterparties to the agreements relating to the Company’s investments consist of financial institutions of high credit standing. The Company provides for uncollectible amounts when specific credit problems arise. Management’s estimates for uncollectible amounts have been adequate, and management believes that all significant credit risks have been identified at March 31, 2022 and December 31, 2021.

The Company’s accounts receivable are due from a variety of healthcare organizations in the United States and select international markets. At March 31, 2022 and December 31, 2021, there was one customer that represented 13% and 21% of accounts receivable, respectively. For the three months ended March 31, 2022, there was one customer that represented 14% of revenues. For the three months ended March 31, 2021, there were no customers that represented 10% or more of revenues. Disruption of sales orders or a deterioration of financial condition of its customers would have a negative impact on the Company’s financial position and results of operations.

Product Warranty Costs

The Company typically offers a one-year warranty on its products commencing upon the transfer of title and risk of loss to the customer. The Company accrues for the estimated cost of product warranties upon invoicing its customers, based on historical results. Warranty costs are reflected in the statement of operations and comprehensive loss as a cost of revenues. The warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage or service delivery costs differ from these estimates, revisions to the estimated warranty liability would be required. Periodically the Company assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. Warranty provisions and claims are summarized as follows (in thousands):

Net Loss per Share Attributable to Common Stockholders

Basic net loss per share applicable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period, without consideration for potential dilutive common shares. Diluted net loss per share applicable to common stockholders is computed by dividing the net loss attributable to common stockholder by the weighted average number of shares of common stock and dilutive potential shares of common stock outstanding during the period. Any common stock shares subject to repurchase are excluded from the calculations as the continued vesting of such shares is contingent upon the holders’ continued service to the Company. As of March 31, 2022 and 2021, there were no shares subject to repurchase. Since the Company was in a loss position for both periods presented, basic net loss per share applicable to common stockholders is the same as diluted net loss per share applicable to common stockholders as the inclusion of all potentially dilutive common shares would have been anti-dilutive.

Net loss per share applicable to common stockholders was determined as follows (in thousands, except per share data):

The following potentially dilutive securities outstanding have been excluded from the computations of diluted weighted average shares outstanding because such securities have an anti-dilutive impact due to losses reported:

Segment and Geographical Information

The Company operates and manages its business as one reportable and operating segment. The Company’s chief executive officer, who is the chief operating decision maker, reviews financial information on an aggregate basis for purposes of allocating resources and evaluating financial performance. Primarily all of the Company’s long-lived assets, which are comprised of property and equipment, are based in the United States. For both the three months ended March 31, 2022 and 2021, 94% of the Company’s revenues were in the United States, based on the shipping location of the external customer.

As of March 31, 2022 and December 31, 2021, cash equivalents were all categorized as Level 1 and consisted of money market funds. As of March 31, 2022 and December 31, 2021, there were no financial assets and liabilities categorized as Level 2 or 3. There were no transfers between fair value hierarchy levels during the three months ended March 31, 2022.

Recent Accounting Pronouncements

Recently adopted accounting standards

In May 2021, ASU No. 2021-04, Issuer’s Accounting for Certain Modifications of Exchanges of Freestanding Equity-Classified Written Call Options was issued to clarify the accounting for modifications or exchanges of freestanding equity-classified written call options, such was warrants, that remain equity classified after modification or exchange. The standard was adopted by the Company on January 1, 2022. This new standard did not have a material impact on the Company’s financial statements.

Recent accounting standards not yet adopted

In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which among other things, simplifies the accounting models for the allocation of proceeds attributable to the issuance of a convertible debt instrument.  As a result, after adopting the ASU’s guidance, entities will not separately present in equity an embedded conversion feature in such debt. Instead, they will account for a convertible debt instrument wholly as debt, and for convertible preferred stock wholly as preferred stock (i.e., as a single unit of account), unless (i) a convertible instrument contains features that require bifurcation as a derivative under ASC 815 or (ii) a convertible debt instrument was issued at a substantial premium. The standard becomes effective for the Company, as a smaller reporting company as defined by the SEC, in the first quarter of 2024 and early adoption is permitted.  This new standard is not expected to have a material impact on the Company’s financial statements.

Inventories consisted of the following (in thousands):

4. Borrowings

CRG

On September 22, 2015, the Company entered into a Term Loan Agreement, as amended (the “Loan Agreement”) with CRG under which, subject to certain conditions, the Company had the right to borrow up to $50 million in principal amount from CRG on or before March 29, 2017. The Company borrowed $30 million on September 22, 2015. The Company borrowed an additional $10 million on June 15, 2016 under the Loan Agreement.

On February 14, 2018, the Company and CRG further amended the Loan Agreement concurrent with the conversion of $38 million of the principal amount of the senior secured term loan (plus $3.8 million in back-end fees and prepayment premium applicable thereto) into a newly authorized Series A convertible preferred stock (see below).

We have entered into several amendments to the Term Loan Agreement (the “Amendments”) with CRG since September 2015, the most recent of which, was entered into on January 22, 2021. The Amendments, among other things: (1) extended the interest-only period through December 31, 2023; (2) extended the period during which we may elect to pay a portion of interest in payment-in-kind, or PIK, interest payments through December 31, 2023 so long as no default has occurred and is continuing; (3) permitted us to make our entire interest payments in PIK interest payments for through December 31, 2023 so long as no default has occurred and is continuing; (4) extended the maturity date to December 31, 2025; (5) reduced the minimum liquidity requirement to $3.5 million at all times; (6) eliminated the minimum revenue covenant for 2018, 2019 and 2020; (7) reduced the minimum revenue covenant to $8 million for 2021, $10 million for 2022; (8) added minimum revenue covenants for of $12 million for 2023, $14.5 million for 2024 and $17 million for 2025; (9) changed the date under the on-going stand-alone representation regarding no “Material Adverse Change” to December 31, 2020; (10) amended the on-going stand-alone representation and stand-alone event of default regarding Material Adverse Change such that any adverse change in or effect upon the revenue of us and our subsidiaries due to the outbreak of COVID-19 will not constitute a Material Adverse Change; and (11) provided CRG with board observer rights.

Under the amended Loan Agreement, no cash payments for either principal or interest are due until the first quarter of 2024. The interest will be accrued and included in the debt balance based (to the extent not paid) on principal amounts outstanding at the beginning of the quarter at an interest rate of 12.5%. Beginning in the first quarter of 2024, the Company will be required to make quarterly principal payments (in addition to the interest) of $1.9 million with total principal payments of $7.5 million in 2024, and $7.5 million in 2025. The maturity date of the Loan is December 31, 2025.

The Company may voluntarily prepay the borrowings in full, with a prepayment premium beginning at 5.0% and declining by 1.0% annually thereafter, with no premium being payable if prepayment occurs after seven and half years of the loan. Each tranche of borrowing required the payment, on the borrowing date, of a financing fee equal to 1.5% of the borrowed loan principal, which is recorded as a discount to the debt. In addition, a facility fee equal to 15.0% of the amounts borrowed plus any payment-in-kind (“PIK”) is to be payable at the end of the term or when the borrowings are repaid in full. A long-term liability is being accreted using the effective interest method for the facility fee over the term of the Loan Agreement with a corresponding discount to the debt. The borrowings are collateralized by a security interest in substantially all of the Company’s assets.

The Loan Agreement requires that the Company adheres to certain affirmative and negative covenants, including financial reporting requirements, certain minimum financial covenants for pre-specified liquidity and revenue requirements and a prohibition against the incurrence of indebtedness, or creation of additional liens, other than as specifically permitted by the terms of the Loan Agreement. In particular, the covenants of the amended Loan Agreement included a covenant that the Company maintain a minimum of $3.5 million of cash and certain cash equivalents, and the Company has to achieve certain minimum revenues. If the Company fails to meet the applicable minimum revenue target in any calendar year, the Loan Agreement provides the Company with a cure right if it prepays a portion of the outstanding principal equal to 2.0 times the revenue shortfall. In addition, the Loan Agreement prohibits the payment of cash dividends on the Company’s capital stock and also places restrictions on mergers, sales of assets, investments, incurrence of liens, incurrence of indebtedness and transactions with affiliates. CRG may accelerate the payment terms of the Loan Agreement upon the occurrence of certain events of default set forth therein, which include the failure of the Company to make timely payments of amounts due under the Loan Agreement, the failure of the Company to adhere to the covenants set forth in the Loan Agreement, the insolvency of the Company or upon the occurrence of a material adverse change.

As of March 31, 2022, the Company was in compliance with all applicable covenants under the Loan Agreement.

As of March 31, 2022, principal, final facility fee and PIK payments under the Loan Agreement, which incorporates all aforementioned amendments, were as follows (in thousands):

In connection with drawdowns under the Loan Agreement, the Company recorded aggregate debt discounts of $1.3 million as contra-debt. The debt discounts are being amortized as non-cash interest expense using the effective interest method over the term of the Loan Agreement. As of March 31, 2022 and December 31, 2021, the balance of the aggregate debt discount was approximately $312,000 and $333,000, respectively. The Company’s interest expense associated with the amortization of debt discount was approximately $21,000 and $38,000 during the three months ended March 31, 2022 and 2021, respectively. For the three months ended March 31, 2022 and 2021, the Company incurred total interest expense of approximately $440,000 and $393,000, respectively.

As of March 31, 2022, all of the CRG borrowings and associated aggregate debt discount were classified as non-current.

Paycheck Protection Program

On April 23, 2020, the Company received loan proceeds of $2.3 million (the “PPP Loan”) pursuant to the PPP under the CARES Act. The PPP Loan, which was in the form of a promissory note, dated April 20, 2020 (the “Promissory Note”), between the Company and Silicon Valley Bank (“SVB”) as the lender, was set to mature on April 20, 2022 and bore interest at a fixed rate of 1% per annum, payable monthly commencing six months from the date of the Loan. The Company may voluntarily prepay the borrowings in full with no associated penalty or premium.

The PPP Loan was administered by the U.S. Small Business Administration (the “SBA”). The SBA was given the authority under the PPP to forgive loans if all employees were kept on the payroll for a required period and the loan proceeds were used for payroll, rent and utilities. The Company applied for debt forgiveness in December 2020.

On April 17, 2021, the Company was notified by SVB that its PPP Loan had been fully forgiven by the SBA and that there was no remaining balance on the PPP Loan. The Company recorded the forgiveness as other income in April 2021 in the amount of $2.4 million, of which approximately $23,000 was accrued interest. For the quarter ended March 31, 2021, the Company incurred interest expense of approximately $6,000 related to the PPP Loan.

5. Leases

The Company’s operating lease obligations primarily consist of leased office, laboratory, and manufacturing space under a non-cancelable operating lease. In addition to the minimum future lease commitments presented below, the lease requires the Company to pay property taxes, insurance, maintenance, and repair costs. The lease includes a rent holiday concession and escalation clauses for increased rent over the lease term. Rent expense is recognized using the straight-line method over the term of the lease. The Company records deferred rent calculated as the difference between rent expense and the cash rental payments.

The lease will expire on November 30, 2024. The Company is obligated to pay approximately $5.8 million in base rent payments through November 2024, beginning on December 1, 2019. The weighted average remaining lease term as of March 31, 2022 is 2.7 years.

The operating lease was included on the balance sheet at the present value of the future base payments discounted at a 6.5% discount rate using the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term and amount equal to the lease payments in a similar economic environment as the lease does provide an implicit rate.

The Company’s operating lease expense, excluding variable maintenance fees and other expenses on a monthly basis, was approximately $105,000. Rent expense for both the three months ended March 31, 2022 and 2021 was approximately $314,000. The Company’s variable expenses for the three months ended March 31, 2022 and 2021 were approximately $66,000 and $59,000, respectively. Operating right-of-use asset amortization for the three months ended March 31, 2022 and 2021 was approximately $264,000 and $249,000, respectively. Due to payments being made in excess of operating lease expense recognized, the Company recorded approximately $150,000 and $158,000 as prepaid rent included in other assets on the condensed balance sheet as of March 31, 2022 and December 31, 2021, respectively.

6. Commitments and Contingencies

Purchase Obligations

Purchase obligations consist of agreements to purchase goods and services entered into in the ordinary course of business. The Company had non-cancelable commitments to suppliers for purchases totaling approximately $1.2 million as of March 31, 2022. The majority of this amount is related to commitments to purchase inventory components for our various product lines.

Legal Proceedings

The Company is not currently involved in any pending legal proceedings that the Company believes could have a material adverse effect on our financial condition, results of operations or cash flows. From time to time, the Company may be involved in legal proceedings or investigations, which could harm our reputation, business and financial condition and divert the attention of our management from the operation of our business.

7. Stockholders’ Equity

Convertible Preferred Stock

As of March 31, 2022 and December 31, 2021, the Company’s certificate of incorporation, as amended and restated, authorizes the Company to issue up to 5,000,000 shares of convertible preferred stock with $0.001 par value per share. As of March 31, 2022 and December 31, 2021, 58,851 and 56,451 shares were issued and outstanding, respectively.

Series A Convertible Preferred Stock

The holders of Series A preferred stock are entitled to receive annual accruing dividends at a rate of 8%, payable in additional shares of Series A preferred stock or cash, at the Company’s option. The shares of Series A preferred stock have a liquidation preference of $1,000 per share, no voting rights and rank senior to all other classes and series of the Company’s equity in terms of repayment and certain other rights. During the year ended December 31, 2021, 4,175 additional shares were issued to CRG as payment of dividends. As of March 31, 2022 and December 31, 2021, 56,366 shares of Series A preferred stock were outstanding, which are currently convertible into shares of the Company’s common stock at $400 per share. The Series A preferred stock accrued additional dividends of approximately $1.1 million and $1.0 million during the quarters ended March 31, 2022 and 2021, respectively.

Series B Convertible Preferred Stock

The Series B preferred stock has a liquidation preference of $0.001 per share, full ratchet price based anti-dilution protection, has no voting rights and is subject to certain ownership limitations. The Series B preferred stock is immediately convertible at the option of the holder, has no stated maturity, and does not pay regularly stated dividends or interest. During the year ended December 31, 2021, 93 of these shares converted into 18,600 shares of common stock. As of March 31, 2022 and December 31, 2021, 85 shares of Series B preferred stock remained outstanding, which are currently convertible into shares of the Company’s common stock at $5 per share.

Series D Convertible Preferred Stock

On January 14, 2022, the Company entered into a security purchase agreement with several institutional investors, pursuant to which the Company agreed to sell and issue, in a registered direct offering ( “January 2022 Offering”), an aggregate of 7,600 shares of the Company’s Series D convertible preferred stock, par value $0.001 per share at an offering price of $1,000 per share. Concurrently, the Company agreed to issue to these investors warrants to purchase up to an aggregate of 807,500 shares of the Company’s common stock (the “Common Warrants”). The shares of Series D preferred stock has a stated value of $1,000 per share and are convertible into an aggregate of 950,000 shares of common stock at a conversion price of $8.00 per share. During the three months ended March 31, 2022, 5,200 of these shares converted into 650,000 shares of common stock. As of March 31, 2022, 2,400 shares of Series D preferred stock were outstanding, which are currently convertible into shares of the Company’s common stock at $8 per share.

On April 1, 2022 and on May 6, 2022, a holder of Series D preferred stock opted to convert some of their Series D preferred stock into common stock. A total of 600 and 1,200 shares of Series D preferred stock were converted resulting in the issuance of an aggregate of 75,000 and 150,000 shares of common stock, respectively. After giving effect to these conversion, there remains 600 shares of Series D preferred stock, which if converted, would result in the issuance of 75,000 shares of common stock.

The Series D preferred stock can be converted at the option of the holders at any time. In addition, subject to the satisfaction of certain conditions, the Company may cause the holders of the Series D preferred stock to convert their shares of Series D preferred stock; provided, that shares of Series D preferred stock cannot be converted to common stock if the applicable holder would beneficially own in excess of 4.99% (or, upon election by such holder prior to the issuance of any shares of Series D preferred stock, 9.99%) of our outstanding common stock. A holder of Series D preferred stock may, upon notice to us, increase or decrease such beneficial ownership limitation, but not in excess of 9.99%. The Series D preferred stock have a liquidation preference equal to $0.01 per share of Series D preferred stock.

The Series D preferred stock does not have any mandatory redemption provisions, contingently redeemable redemption provisions, preferential dividend rights, or voting rights, apart from mirrored, non-discretionary voting rights with common stock as a single class, equal to 37,500 votes per share of common stock underlying the preferred stock on a one-time proposal (the “Proposal”) to amend to the Company’s Amended and Restated Certificate of Incorporation, as amended (the “Charter”) to effect a reverse split of the outstanding shares of the Company’s common stock at a ratio between 1-for-5 and 1-for-20 (the “Reverse Split Amendment”) which was approved by the Company’s stockholders at a special stockholder meeting on March 11, 2022.

The Company evaluated the classification of the Series D preferred stock and determined equity classification was appropriate due to no mandatory or contingently redeemable redemption features. The warrants issued to the investors were considered freestanding equity classified instruments. The Company first allocated gross proceeds from the registered direct offering between the preferred stock and the warrants issued to investors using a relative fair value approach, resulting in an initial allocation to each instrument of $4,009 and $3,591, respectively. On the issuance date, the Company estimated the fair value of the warrants issued to investors (the “Common Warrants”) and to placement agent designees using a Black-Scholes option pricing model using the following assumptions: (i) contractual term of 5.5 years, (ii) expected volatility rate of 136.61%, (iii) risk-free interest rate of 1.51%, (iv) expected dividend rate of 0%, and (v) closing price of the Company’s common stock of the day immediately preceding the registered direct offering. The fair value of preferred stock was estimated based upon equivalent common shares that preferred stock could have been converted into at the closing price of the day immediately preceding the purchase date.

The embedded conversion feature was evaluated and bifurcation from the preferred stock equity host was not considered necessary. The issuance of the Series D convertible preferred stock generated a beneficial conversion feature (“BCF”) which arose as the equity security was issued with an embedded conversion option that is beneficial to the investor or in the money at inception because the conversion option has an effective conversion price that is less than the market price of the underlying stock at the commitment date. The Company recorded the BCF as a discount to the preferred stock resulting in the amount of $5,111 based on the intrinsic value of the beneficial conversion. As the preferred stock was immediately convertible into common stock subject to the consummation of the reverse stock split on March 14, 2022, a deemed dividend related to the discount associated with the beneficial conversion feature was recorded on that date. This one-time, non-cash charge impacted net loss applicable to common stockholders and net loss per share attributable to common stockholders for the three months ended March 31, 2022.

Common Stock

As of March 31, 2022, the Company’s certificate of incorporation, as amended and restated, authorizes the Company to issue up to 100,000,000 shares of common stock with $0.001 par value per share, of which 5,454,849 shares were issued and outstanding.

Common Stock Warrants

As of March 31, 2022, the Company had outstanding warrants to purchase common stock as follows:

Pursuant to the purchase agreement entered into on January 14, 2022, the Company issued the Common Warrants to purchase up to an aggregate of 807,500 shares of the Company’s common stock at an exercise price of $9.60 per share and which become exercisable beginning July 14, 2022. The Common Warrants will expire five years following the time they become exercisable, or July 14, 2027. The exercise price and the number of shares of common stock issuable upon exercise of each common warrant is subject to appropriate adjustments in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the common stock. In addition, in certain circumstances, upon a fundamental transaction, a holder of Common Warrants will be entitled to receive, upon exercise, the kind and amount of securities, cash or other property that such holder would have received had they exercised the Common Warrants immediately prior to the fundamental transaction.

The Common Warrants can be exercised at the option of the holders at any time after they become exercisable provided that shares of the Common Warrants cannot be exercised into common stock if the applicable holder would beneficially own in excess of 4.99% (or, upon election by such holder prior to the issuance of any shares of Common Warrants, 9.99%) of the Company’s outstanding common stock immediately after giving effect to the exercise. A holder of the Common Warrants may, upon notice to the Company, increase or decrease such beneficial ownership limitation, but not in excess of 9.99%.

The Company also issued to the placement agent of the January 2022 Offering warrants to purchase up to an aggregate of 66,500 shares of common stock (the “Placement Agent Warrants”). The Placement Agent Warrants are subject to the same terms as the Common Warrants, except that the Placement Agent Warrants have an exercise price of $10.00 per share and a term of five years from the commencement of the sales pursuant to the January 2022 Offering, or January 12, 2027.

As of March 31, 2022 and December 31, 2021, warrants to purchase an aggregate of 1,006,285 and 132,265 shares of common stock were outstanding, respectively.

Stock Plans

In January 2015, the Board of Directors adopted and the Company’s stockholders approved the 2015 Equity Incentive Plan (“2015 Plan”). As of March 31, 2022, 8,564 shares were available for grant under the 2015 Plan.

The Company’s RSUs generally vest annually over three years in equal increments. The Company measures the fair value of RSUs using the closing stock price of a share of the Company’s common stock on the grant date and is recognized as expense on a straight-line basis over the vesting period of the award. A summary of all RSU activity is presented below:

As of  March 31, 2022, there was approximately $0.1 million of remaining unamortized stock-based compensation expense associated with RSUs, which will be expensed over a weighted average remaining service period of approximately 0.5 years. The outstanding non-vested and expected to vest RSUs at March 31, 2022 have an aggregate fair value of less than $0.1 million. The Company used the closing market price of $3.63 per share at March 31, 2022, to determine the aggregate fair value for the RSUs outstanding at that date. For the three months ended March 31, 2022 and 2021, the fair value of RSUs vested was approximately $3,000 and $87,000 respectively. For the three months ended March 31, 2022 and 2021, stock-based compensation expense recognized associated with the vesting of RSUs was $52,000 and $0.4 million, respectively.

2018 Officer and Director Share Purchase Plan

On August 22, 2018, the Board of Directors of the Company approved the adoption of an Officer and Director Share Purchase Plan (“ODPP”), which allows executive officers and directors to purchase shares of our common stock at fair market value in lieu of salary or, in the case of directors, director fees. Eligible individuals may voluntarily participate in the ODPP by authorizing payroll deductions or, in the case of directors, deductions from director fees for the purpose of purchasing common stock. The Board of Directors authorized 1,000 shares to be made available for purchase by officers and directors under the ODPP. Effective on August 28, 2019 and March 10, 2020, the Board of Directors approved an additional 2,000 and 6,250 shares, respectively, to be made available under the ODPP. There was no common stock issued under the ODPP during either the three months ended March 31, 2022 or 2021. As of March 31, 2022, there were 4,609 shares reserved for issuance under the ODPP.

Total non-cash stock-based compensation expense relating to the Company’s stock options and RSUs recognized during the three months ended March 31, 2022 and 2021, is as follows (in thousands):

9. Subsequent Events

Departure of Officer

On April 29, 2022, Mark Weinswig, the Chief Financial Officer of the Company, provided notice to the Company of his resignation as Chief Financial Officer of the Company effective end-of-day May 12, 2022. Concurrent with his departure, the Company expects to adjust certain accrued compensation in the amount of $0.1 million that will no longer have to be paid with respect to Mr. Weinswig.

You should read the following discussion and analysis of our financial condition and results of operations together with the unaudited financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q. This discussion and other parts of this Quarterly Report on Form 10-Q contain forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions, that are based on the beliefs of our management, as well as assumptions made by, and information currently available to, our management. Our actual results could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in the sections of this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K filed with the SEC on March 22, 2022 titled “Risk Factors.”

Overview

We are a commercial-stage medical device company that designs, manufactures and sells real-time image-guided, minimally invasive catheter-based systems that are used by physicians to treat patients with peripheral artery disease, or PAD. Patients with PAD have a build-up of plaque in the arteries that supply blood to areas away from the heart, particularly the pelvis and legs. Our mission is to significantly improve the treatment of vascular disease through the introduction of products based on our Lumivascular platform, the only intravascular real-time image-guided system available in this market.

We design, manufacture, and sell a suite of products in the United States and select international markets. We are located in Redwood City, California. Our current Lumivascular platform consists of products including our Lightbox real-time imaging console, the Ocelot family of catheters, which are image-guided catheters designed to allow physicians to penetrate a total blockage in an artery, known as a chronic total occlusion, or CTO, and the Pantheris family of catheters, our image-guided atherectomy family of catheters which is designed to allow physicians to precisely remove arterial plaque in PAD patients.

We are in the process of developing CTO crossing devices to target the coronary CTO market. The market for medical devices in the coronary artery disease (“CAD”) market is highly competitive, dynamic, and marked by rapid and substantial technological development and product innovation and there is no guarantee that we will be successful in developing and marketing any new CAD product. We are working on understanding market requirements and beginning the development process for the new CAD product. We anticipate that we will incur additional expenses as we continue to evaluate and develop potential CAD products.

We received CE Marking for our original Ocelot product in September 2011 and received from the U.S. Food and Drug Administration, or FDA, 510(k) clearance in November 2012. We received 510(k) clearance from the FDA for commercialization of Pantheris in October 2015. We received an additional 510(k) clearance for an enhanced version of Pantheris in March 2016 and commenced sales of Pantheris in the United States and select European countries promptly thereafter.

In May 2018, we received 510(k) clearance from the FDA for our current next-generation version of Pantheris. In April 2019, we received 510(k) clearance from the FDA for our Pantheris SV, a version of Pantheris targeting smaller vessels, and commenced sales in July 2019. In September 2020, we received 510(k) clearance of Tigereye, a next-generation CTO crossing system utilizing Avinger’s proprietary image-guided technology platform. Tigereye is a product line extension of Avinger’s Ocelot family of image-guided CTO crossing catheters. In January 2022, we received 510(k) clearance from the FDA for our Lightbox 3 imaging console, a version of our Lightbox presenting significant reductions in size, weight and cost in comparison to the incumbent version.

Current treatments for PAD, including bypass surgery, can be costly and may result in complications, high levels of post-surgery pain, and lengthy hospital stays and recovery times. Minimally invasive, or endovascular, treatments for PAD include stenting, angioplasty, and atherectomy, which is the use of a catheter-based device for the removal of plaque. These treatments all have limitations in their safety or efficacy profiles and frequently result in recurrence of the disease, also known as restenosis. We believe one of the main contributing factors to high restenosis rates for PAD patients treated with endovascular technologies is the amount of vascular injury that occurs during an intervention. Specifically, these treatments often disrupt the membrane between the outermost layers of the artery, which is referred to as the external elastic lamina, or EEL.

We believe our Lumivascular platform is the only technology that offers real-time visualization of the inside of the artery during PAD treatment through the use of optical coherence tomography, or OCT, a high resolution, light-based, radiation-free imaging technology. Our Lumivascular platform provides physicians with real-time OCT images from the inside of an artery, and we believe Ocelot and Pantheris are the first products to offer intravascular visualization during CTO crossing and atherectomy, respectively. We believe this approach will significantly improve patient outcomes by providing physicians with a clearer picture of the artery using radiation-free image guidance during treatment, enabling them to better differentiate between plaque and healthy arterial structures. Our Lumivascular platform is designed to improve patient safety by enabling physicians to direct treatment towards the plaque, while avoiding damage to healthy portions of the artery.

During the first quarter of 2015, we completed enrollment of patients in VISION, a clinical trial designed to support our August 2015 510(k) submission to the FDA for our Pantheris atherectomy device. VISION was designed to evaluate the safety and efficacy of Pantheris to perform atherectomy using intravascular imaging and successfully achieved all primary and secondary safety and efficacy endpoints. We believe the data from VISION allows us to demonstrate that avoiding damage to healthy arterial structures, and in particular disruption of the external elastic lamina, which is the membrane between the outermost layers of the artery, reduces the likelihood of restenosis, or re-narrowing, of the diseased artery. Although the original VISION study protocol was not designed to follow patients beyond six months, we worked with 18 of the VISION sites to re-solicit consent from previous clinical trial patients in order for them to evaluate patient outcomes through 12 and 24 months following initial treatment. Data collection for the remaining patients from participating sites was completed in May 2017, and we released the final 12- and 24-month results for a total of 89 patients in July 2017.

During the fourth quarter of 2017, we began enrolling patients in INSIGHT, a clinical trial designed to support a submission to the FDA to expand the indication for our Pantheris atherectomy device to include in-stent restenosis. Patient enrollment began in October 2017 and was completed in July 2021. Patient outcomes are being evaluated at thirty days, six months and one year following treatment. In November 2021, we received 510(k) clearance from the FDA for a new clinical indication for treating in-stent restenosis with Pantheris using the data collected and analyzed from INSIGHT. We expect this will expand our addressable market for Pantheris to include a high-incidence disease state for which there are few available indicated treatment options.

We focus our direct sales force, marketing efforts and promotional activities on interventional cardiologists, vascular surgeons and interventional radiologists. We also work on developing strong relationships with physicians and hospitals that we have identified as key opinion leaders. Although our sales and marketing efforts are directed at these physicians because they are the primary users of our technology, we consider the hospitals and medical centers where the procedure is performed to be our customers, as they typically are responsible for purchasing our products. We are designing additional future products to be compatible with our Lumivascular platform, which we expect to enhance the value proposition for hospitals to invest in our technology. Pantheris qualifies for existing reimbursement codes currently utilized by other atherectomy products, further facilitating adoption of our products.

We have assembled a team with extensive medical device development and commercialization experience in both start-up and large, multi-national medical device companies. We assemble all of our products at our manufacturing facility but certain critical processes, such as coating and sterilization, are performed by outside vendors. We expect our current manufacturing facility in California, will be sufficient through at least 2022. We generated revenues of $8.8 million in 2020 and $10.1 million in 2021. The lower revenues in 2020 was primarily due to the adverse effects of COVID-19 on our customers as hospitals deferred elective procedures. Revenues in 2021 and 2022 continue to fluctuate due to COVID-19.

Recent Developments

COVID-19 Update

As a result of the effects of the COVID-19 pandemic, we experienced a significant decline in sales, particularly as individuals, as well as hospitals and other medical providers, deferred elective procedures in response to COVID-19. We have continued to experience fluctuating sales as practitioners in certain jurisdictions were able to perform elective procedures while other jurisdictions were continuing to experience capacity issues. While at present, a majority of jurisdictions have eased or are in the process of lifting restrictions on performing elective procedures, we cannot be certain that other jurisdictions in the United States will do so in the near future, or that such restrictions will not be adopted again in the future. Some jurisdictions have experienced and continue to experience a resurgence in COVID-19 cases, which has prompted certain hospitals and other medical providers in such areas to again defer elective procedures or further prolong or reinstate existing restrictions on such procedures. If other jurisdictions experience a resurgence in COVID-19 cases, these jurisdictions may also prolong restrictions on elective procedures. This situation has created a significant amount of volatility in the medical industry which makes future developments and results difficult to predict. We believe COVID-19 has had and will continue to have an adverse effect on our ability to generate sales due to the fluctuating and unpredictable levels of capacity medical providers have to perform procedures that require the use of our products as was the case during the three months ended March 31, 2022. Consequently, it is unclear whether any reduction in sales from levels experienced prior to COVID-19 is temporary and whether such sales may be recoverable in the future. In addition, we have experienced disruptions in our manufacturing and supply chain, as well as delays in site initiation and patient enrollment for our clinical studies. If we are unable to successfully complete these or other clinical studies, our business and results of operations could be harmed.

The COVID-19 pandemic and responses thereto have resulted in reduced consumer and investor confidence, instability in the credit and financial markets, volatile corporate profits, and reduced business and consumer spending, which could increase the cost of capital and/or limit the availability of capital to us in the future. These and other factors could adversely affect our ability to effectively manage our available cash and other resources.

Nasdaq Delisting Notice

On September 22, 2021, we received a letter from Nasdaq’s Listing Qualifications Department notifying us that we were not in compliance with Nasdaq Listing Rule 5550(a)(2), as the minimum bid price for our listed securities was less than $1 for the previous 30 consecutive business days. We had a period of 180 calendar days, or until March 21, 2022, to regain compliance with the rule referred to in this paragraph. We did not regain compliance with the minimum bid price requirement by March 21, 2022. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we provided written notice to Nasdaq of our intent to cure the deficiency and, on March 22, 2022, we received notice that Nasdaq granted us an additional 180 calendar days, or until September 19, 2022, to regain compliance.

On March 29, 2022, we received a letter from Nasdaq notifying us that the Staff had determined that the closing bid price of our common stock had been at $1.00 per share or greater for at least 10 consecutive business days and, accordingly, that we had regained compliance with the minimum bid price requirement for continued listing on the Nasdaq Stock Market and that the matter is now closed. While we have regained compliance with the minimum bid price requirement, there can be no assurance that we will be able to maintain compliance with the minimum bid price requirement or Nasdaq’s other continued listing requirements in the future.

Global Supply Chain

We are closely monitoring the impacts of COVID-19 and general economic conditions on global supply chain, manufacturing, and logistics operations. As inflationary pressures increase, we anticipate that our production and operating costs may similarly increase, including costs and availability of materials and labor. In addition, COVID-19 and other events, including port closures or labor shortages, have resulted in manufacturing and shipping constraints generally. While we have had sufficient inventory on-hand to meet our current production requirements and customer demand, we have experienced some constraints with respect to the availability of certain materials and extended lead times from certain key suppliers. We have also experienced some delays in shipping products to our customers. Any significant delay or interruption in our supply chain could impair our ability to meet the demands of our customers in the future and could harm our business.

We may need to identify and qualify new suppliers in response to disruptions and difficulties experienced by some of our current suppliers. The process of identifying and qualifying suppliers is lengthy with no guarantee of ultimately mitigating the current issues experience by the Company. This process can include but is not limited to delays in qualification, quality issues on components, and higher costs to source these components. All of these issues may impair our ability to meet the demands of our customers in the future. 

Reverse Stock Split

On March 11, 2022, our Board of Directors approved an amendment to our amended and restated certificate of incorporation to effect a 1-for-20 reverse stock split of our issued and outstanding common stock. The reverse stock split became effective on March 14, 2022. The par value of the common stock and preferred stock was not adjusted as a result of the reverse stock split. All common stock, stock options, and restricted stock units, and per share amounts in the financial statements have been retroactively adjusted for all periods presented to give effect to the reverse stock splits.

Financing

During the three months ended March 31, 2022, our net loss and comprehensive net loss was $5.1 million; during the years ended December 31, 2021 and 2020, it was $17.4 million and $19.0 million, respectively. We have not been profitable since inception, and as of March 31, 2022, our accumulated deficit was $389.9 million. Since inception, we have financed our operations primarily through private and public placements of our preferred and common securities and, to a lesser extent, debt financing arrangements.

In September 2015, we entered into a Term Loan Agreement, or Loan Agreement, with CRG Partners III L.P. and certain of its affiliated funds, collectively CRG, under which we were able to borrow up to $50.0 million on or before March 29, 2017, subject to certain terms and conditions. We borrowed $30.0 million on September 22, 2015 and an additional $10.0 million on June 15, 2016 under the Loan Agreement. Contemporaneously with the execution of the Loan Agreement, we entered into a Securities Purchase Agreement with CRG, pursuant to which CRG purchased 44 shares of our common stock on September 22, 2015 at a price of $111,928 per share, which represents the 10-day average of closing prices of our common stock ending on September 21, 2015. Pursuant to the Securities Purchase Agreement, we filed a registration statement covering the resale of the shares sold to CRG and must comply with certain affirmative covenants during the time that such registration statement remains in effect.

On February 14, 2018, we entered into a Series A preferred stock Purchase Agreement (the “Series A Purchase Agreement”) with CRG, pursuant to which it agreed to convert $38.0 million of the outstanding principal amount of its senior secured term loan (plus the back-end fee and prepayment premium applicable thereto) under the Loan Agreement into a newly authorized Series A preferred stock. As discussed in the section of this report titled “Dividend Policy,” the holders of Series A preferred stock are entitled to receive annual accruing dividends at a rate of 8%, payable in additional shares of Series A preferred stock or cash, at our option. The shares of Series A preferred stock have no voting rights and rank senior to all other classes and series of the Company’s equity in terms of repayment and certain other rights.

We have entered into several amendments to the Term Loan Agreement (the “Amendments”) with CRG since September 2015, the most recent of which, was entered into on January 22, 2021. The Amendments, among other things: (1) extended the interest-only period through December 31, 2023; (2) extended the period during which we may elect to pay a portion of interest in payment-in-kind, or PIK, interest payments through December 31, 2023 so long as no default has occurred and is continuing; (3) permitted us to make our entire interest payments in PIK interest payments for through December 31, 2023 so long as no default has occurred and is continuing; (4) extended the maturity date to December 31, 2025; (5) reduced the minimum liquidity requirement to $3.5 million at all times; (6) eliminated the minimum revenue covenant for 2018, 2019 and 2020; (7) reduced the minimum revenue covenant to $8 million for 2021, $10 million for 2022; (8) added minimum revenue covenants for of $12 million for 2023, $14.5 million for 2024 and $17 million for 2025; (9) changed the date under the on-going stand-alone representation regarding no “Material Adverse Change” to December 31, 2020; (10) amended the on-going stand-alone representation and stand-alone event of default regarding Material Adverse Change such that any adverse change in or effect upon the revenue of us and our subsidiaries due to the outbreak of COVID-19 will not constitute a Material Adverse Change; and (11) provided CRG with board observer rights.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and assumptions for the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions and any such differences may be material. There have been no significant and material changes in our critical accounting policies during the three months ended March 31, 2022, as compared to those disclosed in “Management’s Discussion and Analysis of Financial Conditions and Results of Operations - Critical Accounting Policies and Significant Judgments and Estimates” in our most recent Annual Report on Form 10-K, as filed with the SEC on March 22, 2022.

Components of Our Results of Operations

Revenues

All of our revenues are currently derived from sales of our various PAD catheters in the United States and select international markets, Lightbox consoles, and related services. For the three months ended March 31, 2022, there was one customer that represented 14% of revenues. For the three months ended March 31, 2021, there were no customers that represented 10% or more of revenues.

Revenues may fluctuate from quarter to quarter due to a variety of factors including capital equipment purchasing patterns that are typically increased towards the end of the calendar year and decreased in the first quarter and our ability to have product available in light of supply chain challenges. In addition, during the first quarter, our results can be harmed by adverse weather and by resetting of annual patient healthcare insurance plan deductibles, both of which may cause patients to delay elective procedures. In the third quarter, the number of elective procedures nationwide is historically lower than other quarters throughout the year, which we believe is primarily attributable to the summer vacations of physicians and their patients. Additionally, we believe COVID-19 has had and will continue to have an adverse effect on our ability to generate sales due to the fluctuating and unpredictable levels of capacity medical providers have to perform procedures that require the use of our products.

Cost of Revenues and Gross Margin

Cost of revenues consists primarily of costs related to manufacturing overhead, materials and direct labor. We expense all warranty costs and inventory provisions as cost of revenues. We periodically write-down inventory for estimated excess, obsolete and non-sellable inventories based on assumptions about future demand, past usage, changes to manufacturing processes and overall market conditions. A significant portion of our cost of revenues currently consists of manufacturing overhead costs. These overhead costs include the cost of quality assurance, material procurement, inventory control, facilities, equipment and operations supervision and management. We expect overhead costs as a percentage of revenues to become less significant as our production volume increases. Cost of revenues also includes depreciation expense for production equipment, depreciation and related maintenance expense for placed Lightboxes held by customers and certain direct costs such as those incurred for shipping our products.

We calculate gross margin as gross profit divided by revenues. Our gross margin has been and will continue to be affected by a variety of factors, primarily production volumes, manufacturing costs, product yields, headcount, charges for excess and obsolete inventories and cost-reduction strategies. We intend to use our design, engineering and manufacturing capabilities to further advance and improve the efficiency of our manufacturing processes, which we believe will reduce costs and increase our gross margin. In the future, we may seek to manufacture certain of our products outside the United States to further reduce costs. Our gross margin will likely fluctuate from quarter to quarter as we continue to introduce new products and sales channels, and as we adopt new manufacturing processes and technologies.

Research and Development Expenses

Research and development, or R&D, expenses consist primarily of engineering, product development, clinical and regulatory affairs, consulting services, materials, depreciation and other costs associated with products and technologies in development. These expenses include employee compensation, including stock-based compensation, supplies, materials, quality assurance expenses allocated to R&D programs, consulting, related travel expenses and facilities expenses. Clinical expenses include clinical trial design, clinical site reimbursement, data management, travel expenses and the cost of manufacturing products for clinical trials. We expect R&D expenses to vary over time depending on the level and timing of our new product development efforts, as well as our clinical development, clinical trial and other related activities.

Selling, General and Administrative Expenses

Selling, general and administrative, or SG&A, expenses consist primarily of compensation for personnel, including stock-based compensation, selling and marketing functions, physician education programs, business development, finance, information technology and human resource functions. Other SG&A expenses include commissions, training, travel expenses, educational and promotional activities, marketing initiatives, market research and analysis, conferences and trade shows, professional services fees, including legal, audit and tax fees, insurance costs and general corporate expenses. We expect SG&A expenses to increase as we expand our commercial efforts and additional costs related to corporate matters.

Interest Expense, net

Interest expense, net consists primarily of interest incurred on our outstanding indebtedness and non-cash interest related to the amortization of debt discount and issuance costs associated with our various debt agreements.

Other Income, net

Other income, net primarily consists of gains and losses resulting from the remeasurement of foreign exchange transactions and other miscellaneous income and expenses.

Results of Operations:

Comparison of Three Months Ended March 31, 2022 and 2021

Revenues. 

For the three months ended March 31, 2022, revenue decreased by $0.7 million or 26% compared to the three months ended March 31, 2021. The decrease in revenues reflect the fluctuating demand primarily resulting from uncertainties due to COVID-19 as capacity limitations in hospitals have limited the ability of practitioners to perform elective surgical procedures using our products in certain jurisdictions. We anticipate that COVID-19 could continue to impact hospital capacities, and related demand for our products, for the foreseeable future.

Cost of Revenues and Gross Margin.

For the three months ended March 31, 2022, cost of revenues decreased by $0.3 million or 18% compared to the three months ended March 31, 2021. This decrease was primarily attributable to the decrease in revenues. Stock-based compensation expense within cost of revenues totaled $7,000 and $34,000 for the three months ended March 31, 2022 and 2021, respectively.

Gross margin for the three months ended March 31, 2022 decreased to 28%, compared to 35% in the three months ended March 31, 2021. The decrease in gross margin was primarily due to the decrease in revenues and consequently a decrease in economies of scale relating to the decreased levels of production.

Research and Development Expenses (“R&D”).

R&D expense for the three months ended March 31, 2022 decreased $0.5 million or 33% compared to the three months ended March 31, 2021 primarily due to the completion of our development efforts on the Lightbox 3 last fiscal year. Stock-based compensation expense within R&D totaled approximately $13,000 and $0.1 million for the three months ended March 31, 2022 and 2021, respectively.

Selling, General and Administrative Expenses (“SG&A”).

SG&A expense for the three months ended March 31, 2022 increased by $0.2 million or 5%, compared to the three months ended March 31, 2021 primarily due to an increase in third-party professional services and other ancillary expenses. Stock-based compensation expense within SG&A totaled approximately $33,000 and $0.3 million for the three months ended March 31, 2022 and 2021, respectively.

Interest Expense, Net.

Interest expense, net for the three months ended March 31, 2022 increased by 11% or $42,000, compared to the three months ended March 31, 2021, primarily due to the higher CRG loan balance from interest being compounded. Interest income remains low due to the decline in the money market interest rates.

Other Expense, Net. 

Other expense, net primarily consists of gains and losses resulting from the remeasurement of foreign exchange transactions and other miscellaneous income and expenses. Other expense, net for the three months ended March 31, 2022 remained flat in comparison to the three months ended March 31, 2021 as both periods consisted primarily of remeasurement gains and losses from foreign exchange transactions which are typically a small percentage of transaction volume, thus resulting in nominal changes between periods.

Liquidity and Capital Resources

As of March 31, 2022, we had cash and cash equivalents of $20.0 million and an accumulated deficit of $389.9 million, compared to cash and cash equivalents of $19.5 million and an accumulated deficit of $384.8 million as of December 31, 2021. We expect to incur losses for the foreseeable future. We believe that our cash and cash equivalents of $20.0 million at March 31, 2022 and expected revenues, debt and financing activities and funds from operations will be sufficient to allow us to fund our current operations into the second quarter of 2023.

To date, we have financed our operations primarily through net proceeds from the issuance of our preferred stock and debt financings, our “at-the-market” program, our initial public offering, or IPO, our follow-on public offerings and warrant issuances. We do not know when or if our operations will generate sufficient cash to fund our ongoing operations. Additional debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. Any additional debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders and require significant debt service payments, which divert resources from other activities. Additional financing may not be available at all, or if available, may not be in amounts or on terms acceptable to us. If we are unable to obtain additional financing, we may be required to delay the development, commercialization and marketing of our products and we may be required to significantly scale back our business and operations.

In addition, the COVID-19 pandemic and responses thereto have resulted in reduced consumer and investor confidence, instability in the credit and financial markets, volatile corporate profits, restrictions on elective medical procedures, and reduced business and consumer spending, which could increase the cost of capital and/or limit the availability of capital to us. While we have taken certain actions to manage our available cash and other resources to mitigate the effects of COVID-19 on our business, there can be no assurance that such strategies will be successful in mitigating the negative impacts of the COVID-19 pandemic on our liquidity and capital resources.

Equity Financings

On February 2, 2021, under the shelf registration statement, we completed a bought deal offering of 500,000 shares of common stock at an offering price of $28.80 per share. As a result, we received aggregate net proceeds of approximately $13.0 million after underwriting discounts, commissions, legal and accounting fees, and other ancillary expenses.

January 2022 Offering

On January 14, 2022, we entered into a securities purchase agreement with several institutional investors pursuant to which we agreed to sell and issue, in a registered direct offering (“January 2022 Offering”), an aggregate of 7,600 shares of our Series D convertible preferred stock, par value of $0.001 per share, at an offering price of $1,000 per share. Concurrently, we agreed to issue to these investors warrants to purchase up to an aggregate of 807,500 shares of our common stock (the “Common Warrants”). As a result, we received aggregate net proceeds of approximately $6.7 million after underwriting discounts, commissions, legal and accounting fees, and other ancillary expenses.

In connection with the January 2022 Offering and in accordance with the securities purchase agreement, we held a special meeting of stockholders on March 11, 2022 to consider a proposal (the “Proposal”) to amend to our Amended and Restated Certificate of Incorporation, as amended (the “Charter”) to effect a reverse split of the outstanding shares of our common stock at a ratio between 1-for-5 and 1-for-20 (the “Reverse Split Amendment”). Our stockholders approved the Reverse Split Amendment at the special meeting. On March 11, 2022, following receipt of stockholder approval, our Board of Directors approved a reverse split ratio of 1-for-20 and we filed an amendment to our Charter to effect such reverse stock split, effective as of 5:00 pm Eastern Time on March 14, 2022.

Pursuant to the purchase agreement, we filed a certificate of designation (the “Certificate of Designation”) with the Secretary of State of Delaware designating the rights, preferences and limitations of the shares of Series D preferred stock, which became effective on January 14, 2022. The Certificate of Designation provided, in particular, that the Series D preferred stock will have no voting rights, other than the right to vote as a class on certain matters, except that each share of Series D preferred stock had the right to cast 37,500 votes per share of Series D preferred stock on the Proposal (the “Supermajority Voting Rights”); provided, that the votes cast by the holders of the Series D preferred stock must be counted in the same proportion as the aggregate shares of common stock voted on the Proposal. Because the Proposal was approved by our stockholders at the special meeting held on March 11, 2022, the Series D preferred stock no longer has Supermajority Voting Rights.

The holders of the Series D preferred stock are entitled to dividends, on an as-if converted basis, equal to dividends actually paid, if any, on shares of Common Stock. The Series D preferred stock is convertible into shares of common stock at a conversion price of $8.00 per share, as adjusted for the most recent reverse stock split. The conversion price can be adjusted pursuant to the Certificate of Designation for stock dividends and stock splits, subsequent rights offerings, pro rata distributions of dividends or the occurrence of a fundamental transaction (as defined in the Certificate of Designation). The Series D preferred stock can be converted at the option of the holders at any time. In addition, subject to the satisfaction of certain conditions, we may cause the holders of the Series D preferred stock to convert their shares of Series D preferred stock; provided, that shares of Series D preferred stock cannot be converted to common stock if the applicable holder would beneficially own in excess of 4.99% (or, upon election by such holder prior to the issuance of any shares of Series D preferred stock, 9.99%) of our outstanding common stock. A holder of Series D preferred stock may, upon notice to us, increase or decrease such beneficial ownership limitation, but not in excess of 9.99%. In March 2022, after the effectiveness of the Reverse Split Amendment, 5,200 shares of Series D preferred stock were converted into an aggregate of 650,000 shares of common stock.

The Common Warrants have an exercise price of $9.60 per share and become exercisable beginning July 14, 2022. The Common Warrants will expire five years following the time they become exercisable, or July 14, 2027. We also issued to the Placement Agent or its designees warrants to purchase up to an aggregate of 66,500 shares of common stock (the “Placement Agent Warrants”). The Placement Agent Warrants are subject to the same terms as the Common Warrants, except that the Placement Agent Warrants have an exercise price of $10.00 per share and a term of five years from the commencement of the sales pursuant to the January 2022 Offering, or January 12, 2027.

PPP Loan

On April 23, 2020, we received loan proceeds of $2.3 million (the “PPP Loan”) pursuant to the PPP under the CARES Act. The PPP Loan, which was in the form of a promissory note, dated April 20, 2020 (the “Promissory Note”), between us and Silicon Valley Bank (“SVB”) as the lender, was set to mature on April 20, 2022 and bore interest at a fixed rate of 1% per annum.

As previously disclosed, the PPP was administered by the U.S. Small Business Administration (the “SBA”). The SBA was given the authority under the PPP to forgive loans if all employees were kept on the payroll for a required period and the loan proceeds were used for payroll, rent and utilities. The Company applied for debt forgiveness in December 2020. On April 17, 2021, the Company was notified by SVB that its PPP Loan had been fully forgiven by the SBA and that there was no remaining balance on the PPP Loan. The Company recorded the forgiveness as other income in April 2021 in the amount of $2.4 million, of which approximately $23,000 was accrued interest.

Contractual Obligations

Our principal obligations consist of the operating lease for our facility, our Loan Agreement with CRG and non-cancelable purchase commitments. The following table sets out, as of March 31, 2022, our contractual obligations due by period (in thousands):

Cash Flows

Net Cash Used in Operating Activities

Net cash used in operating activities for the three months ended March 31, 2022 was $6.2 million, consisting primarily of a net loss of $5.1 million and an increase in net operating assets of $1.6 million, partially offset by non-cash charges of $0.5 million. Non-cash charges largely related to non-cash interest expense of $0.4 million. The increase in net operating assets was primarily due to the increase in prepaid expenses and other current assets due to annual renewals of certain expenses, including insurance coming due; and purchases of inventory components. These increases were partially offset by the increase in accrued compensation and other long-term liabilities due to timing of payments.

Net cash used in operating activities for the three months ended March 31, 2021 was $4.8 million, consisting primarily of a net loss of $5.1 million and an increase in net operating assets of $0.8 million, offset by non-cash charges of $1.1 million. Non-cash charges largely related to stock-based compensation of $0.4 million, non-cash interest expense of $0.4 million, and depreciation and amortization of $0.2 million. The increase in net operating assets was primarily due to the increase in prepaid expenses and other current assets due to annual renewals of certain expenses, including insurance coming due; partially offset by the increase in accrued expenses and other current liabilities due to timing of payments.

Net Cash Used in Investing Activities

Net cash used in investing activities during both the three months ended March 31, 2022 and 2021 consisted of purchases of property and equipment.

Net Cash Provided by Financing Activities

Net cash provided by financing activities in the three months ended March 31, 2022 of $6.7 million relates to proceeds from the issuance of preferred stock and warrants in the January 2022 Offering, net of commissions and various issuance costs.

Net cash provided by financing activities in the three months ended March 31, 2021 of $13.1 million relates to proceeds from the issuance of common stock in our January 2021 public offering, net of commissions and various issuance costs.

Interest Rate Risk

The risk associated with fluctuating interest rates is primarily limited to our cash equivalents, which are carried at quoted market prices. Due to the short-term maturities and low risk profile of our cash equivalents, an immediate 100 basis point change in interest rates would not have a material effect on the fair value of our cash equivalents. We do not currently use or plan to use financial derivatives in our investment portfolio.

Credit Risk

As of March 31, 2022 and December 31, 2021, our cash and cash equivalents were maintained with one financial institution in the United States, and our current deposits are likely in excess of insured limits. We have reviewed the financial statements of this institution and believe it has sufficient assets and liquidity to conduct its operations in the ordinary course of business with little or no credit risk to us.

Our accounts receivable primarily relate to revenues from the sale of our Lumivascular platform products to hospitals and medical centers in the United States. At March 31, 2022 and December 31, 2021, there was one customer that represented 13% and 21% of accounts receivable.

Foreign Currency Risk

Our business is primarily conducted in U.S. dollars. Any transactions that may be conducted in foreign currencies are not expected to have a material effect on our results of operations, financial position or cash flows.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and the rules and regulations thereunder, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by Rule 13a-15(b) under the Exchange Act, our management, under the supervision and with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of March 31, 2022. Based on such evaluation, our principal executive officer and principal financial officer have concluded that, as of March 31, 2022, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There were no changes in our internal controls over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the three months ended March 31, 2022 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

None.

Our business, financial condition and results of operations can be affected by a number of factors, whether currently known or unknown, including but not limited to those described in Part I, Item 1A of our annual report on Form 10-K for the year ended December 31, 2021 under the heading “Risk Factors.” In addition to those risk factors, the below risk factors are applicable to us. Any one or more of these risk factors could, in whole or in part, directly or indirectly, materially adversely impact our business and stock price and cause our actual financial condition and results of operations to vary materially from its past, or its anticipated future, financial condition and results of operations.

Nasdaq may delist our securities from its exchange, which could harm our business and limit our stockholders’ liquidity.

Our common stock is currently listed on the Nasdaq Capital Market (“Nasdaq”), which has qualitative and quantitative listing criteria. However, we cannot assure you that our common stock will continue to be listed on Nasdaq in the future. In order to continue listing our common stock on Nasdaq, we must maintain certain financial, distribution and stock price levels. Generally, we must maintain a minimum amount in stockholders’ equity, a minimum number of holders of our common stock and a minimum bid price.

In particular, Nasdaq Listing Rule 5550(a) and 5550(b)(1) require us to maintain a minimum stockholders’ equity of $2.5 million. While we are currently in compliance with this rule, we may not be able to maintain compliance in the future. We have, since our inception, incurred net losses and expect we will continue to incur net losses. The decline in our equity is a direct result of our net loss. As we continue to incur losses, our accumulated deficit will continue to increase, which will have a negative impact on our equity balance. Therefore, if we do not continually raise funds through various equity offerings that have an accretive value to our equity, our equity balances will continue to decline. If we are unable to raise capital in a manner that provides accretive value to our equity, our stockholders’ equity may decrease below the minimum required by Nasdaq, which could result in Nasdaq delisting our common stock.

If Nasdaq delists our common stock from trading on its exchange and we are not able to list our securities on another national securities exchange, we expect our securities could be quoted on an over-the-counter market. If this were to occur, we could face significant material adverse consequences, including:

Covenants under the Loan Agreement will restrict our business in many ways.

The Loan Agreement contains various covenants that limit, subject to certain exceptions, our ability to, among other things:

In particular, the Loan Agreement, as most recently amended in January 2021, includes a covenant that we maintain a minimum of $3.5 million of cash and certain cash equivalents, and we will have to achieve minimum revenues of $10.0 million in 2022, $12.0 million in 2023, $14.5 million in 2024 and $17.0 million in 2025. Our revenue for the quarter ended March 31, 2022 was approximately $1.9 million. Based on our annualized revenue as of March 31, 2022, we are not currently on-track to satisfy the minimum revenue covenant for 2022. If we fail to meet the applicable minimum revenue target in any calendar year, the Loan Agreement provides a cure right if we prepay a portion of the outstanding principal equal to 2.0 times the revenue shortfall. Such prepayment would use capital resources that are otherwise required for us to operate our business and, therefore, if we are required to pay such amounts our liquidity and operations could be adversely affected. In addition, if we are unable to make such required prepayment and, as a result, default on our obligations under the Loan Agreement, our business will be adversely affected. There can be no assurance as to our future compliance with the covenants under the Loan Agreement, as amended.

The covenants contained in the Loan Agreement could adversely affect our ability to execute our business strategies by restricting our ability to make capital expenditures, engage in strategic acquisitions, refinance our outstanding indebtedness, or obtain additional financing. Such restrictions may make it difficult to plan for or react to changes in market conditions, such as future downturns in our business or the economy in general.

In addition, potential sources of equity financing may decline to invest in our company given the amount of debt and the rights that debt holders have to get paid before equity holders. In order to facilitate equity investments, future equity investors may require that we convert all or a portion of our debt to equity, and our debtholders may not agree to such terms. The amount of debt could therefore affect our ability to finance our company and prevent us from obtaining necessary operating capital as a result.

We depend on our senior management team and the loss of one or more key employees or an inability to attract and retain highly skilled employees could harm our business.

Our success largely depends upon the continued services of our executive management team and key employees and the loss of one or more of our executive officers or key employees could harm us and directly impact our financial results. Our employees may terminate their employment with us at any time. Changes in our executive management team resulting from the hiring or departure of executives could disrupt our business. For example, our Chief Financial Officer recently provided notice to us that he is resigning effective May 12, 2022. If we are unable to hire one or more replacement employees or otherwise fill his responsibilities, our ability to effectively manage our business could be adversely affected.

We must attract and retain highly qualified personnel. Competition for skilled personnel is intense, especially for engineers with high levels of experience in designing and developing medical devices and for sales professionals. We have, from time to time, experienced, and we expect to continue to experience, difficulty in hiring and retaining employees with appropriate qualifications. Many of the companies with which we compete for experienced personnel have greater resources than we have. If we hire employees from competitors or other companies, their former employers may attempt to assert that these employees or we have breached legal obligations, resulting in a diversion of our time and resources and, potentially, damages. In addition, job candidates and existing employees, particularly in the San Francisco Bay Area, often consider the value of the stock awards they receive in connection with their employment. If the perceived value of our stock awards declines or if we do not make grants of stock-based incentive awards, it may harm our ability to recruit and retain highly skilled employees. In addition, we invest significant time and expense in training our employees, which increases their value to competitors who may seek to recruit them. If we fail to attract new personnel or fail to retain and motivate our current personnel, our business would be harmed.

We depend on third-party vendors to manufacture some of our components, coating and sub-assemblies, including some single source suppliers, which could make us vulnerable to supply shortages and price fluctuations that could harm our business.

We currently manufacture some of our components and sub-assemblies at our Redwood City facility and rely on third-party vendors for other components and sub-assemblies used in our Lumivascular platform. For several of our components and sub-assemblies we rely on single and limited source suppliers. For example, we rely on single vendors for our optical fiber, coatings and drive cables that are key components of our catheters, and we rely on single vendors for our laser and data acquisition card that are key components of our Lightbox. These components are critical to our products and there are relatively few, and in some cases, no alternative sources of supply. Further, we do not carry a significant inventory of these components. If our suppliers of these materials cease doing business, reduce their production capacity, or otherwise limit the amount of materials we can purchase, we may be unable to acquire necessary materials on favorable terms, or at all. If we are unable to purchase required inputs for our production, our business will be adversely affected.

Our reliance on third-party vendors subjects us to a number of risks that could impact our ability to manufacture our products and harm our business.

We rely on third-party vendors to supply us with raw materials, as well as certain components and sub-assemblies used in the manufacture of our products. Our reliance on such third parties subjects us to a number of risks that could adversely affect our operations, including:

The ongoing COVID-19 pandemic, including subsequent variants, and measures taken in response by governments and businesses worldwide to contain its spread, including quarantines, facility closures, travel and logistics restrictions, border controls, and shelter in place or stay at home and social distancing orders, have adversely impacted and are expected to continue to adversely impact global supply chain, manufacturing, and logistics operations. Shipping and freight delays have also been increasing in response to port closures, port congestion, shipping container and ship shortages, and global conflicts. To the extent the COVID-19 pandemic and other events result in continuation or worsening of manufacturing and shipping delays and constraints, our suppliers of raw materials and other components may have difficulty obtaining and providing the materials we require to manufacture our products, which could adversely affect our ability to acquire and maintain adequate inventory and meet demand for our products.

Some of our suppliers have begun requiring us to provide longer-term forecasts of our supply requirements. If our assumptions about customer demand are incorrect, the forecasts we provide to our suppliers may result in excess inventory due to reduced demand or insufficient inventory to meet demand, which would adversely affect our business and results of operations. We also compete with other manufacturers who require the same components as us, or inputs used in producing the components that we purchase. Other purchasers may be able to leverage stronger relationships or greater purchasing power than we have to gain advantages over us in the supply chain.

In addition, any significant delay or interruption in the supply of components or sub-assemblies, or our inability to obtain substitute components, sub-assemblies or materials from alternate sources at acceptable prices in a timely manner, could impair our ability to meet the demand of our customers and harm our business.

Disruptions of supply chains could have a material adverse effect on our operating and financial results

Disruption of supply chains due to trade restrictions, political instability, severe weather, natural disasters, public health crises such as the ongoing COVID-19 pandemic, terrorism, product recalls, port closures, labor supply or stoppages, the financial or operational instability of key suppliers and carriers, government restrictions or measures, or other reasons could impair our ability to distribute our products, or cause the demand for our products to decrease. Many industries, including our own, face supply chain challenges as a result of COVID-19 and other macroeconomic issues, including reduced freight availability and increased costs, port disruption, manufacturing facility closures, labor shortages and other supply chain disruptions. For example, hospitals are currently reporting a shortage of an iodinated contract medium used in X-rays, radiography and CT scans due to Shanghai’s lock-downs. A shortage of such product could lead to a reduced number of surgeries and decrease the demand for our products.

In addition, we have and continue to experience supply chain challenges related to extended lead times from certain key suppliers. Should these challenges persist or worsen, we may be unable to manufacture enough inventory to meet the current demand for our Lumivascular products and consequently incur significant adverse effects on our operating and financial results. To the extent we are unable to mitigate the likelihood or potential impact of such events, there could be a material adverse effect on our operating and financial results.

None.
