Sientra, Inc. (“Sientra”, the “Company,” “we,” “our” or “us”), was incorporated in the State of Delaware on August 29, 2003 under the name Juliet Medical, Inc. and subsequently changed its name to Sientra, Inc. in April 2007. The Company acquired substantially all the assets of Silimed, Inc. on April 4, 2007. The purpose of the acquisition was to acquire the rights to the silicone breast implant clinical trials, related product specifications and pre-market approval, or PMA, assets. Following this acquisition, the Company focused on completing the clinical trials to gain FDA approval to offer its silicone gel breast implants in the United States.

In March 2012, the Company announced it had received approval from the FDA for its portfolio of silicone gel breast implants, and in the second quarter of 2012 the Company began commercialization efforts to sell its products in the United States. The Company, based in Santa Barbara, California, is a medical aesthetics company that focuses on serving board-certified plastic surgeons and offers a portfolio of silicone shaped and round breast implants, scar management, tissue expanders, and body contouring products.

In November 2014, the Company completed an initial public offering, or IPO, and its common stock is listed on the Nasdaq Stock Exchange under the symbol “SIEN.”

On June 11, 2017, Sientra entered into an Agreement and Plan of Merger, or the Merger Agreement, with miraDry (formerly Miramar Labs), pursuant to which Sientra commenced a tender offer to purchase all of the outstanding shares of miraDry’s common stock for (i) $0.3149 per share, plus (ii) the contractual right to receive one or more contingent payments upon the achievement of certain future sales milestones. The total merger consideration was $18.7 million in upfront cash and the contractual rights represent potential contingent payments of up to $14 million. The transaction, which closed on July 25, 2017, added the miraDry System to Sientra’s aesthetics portfolio.

On November 7, 2019, the Company entered into an Asset Purchase Agreement, or the Purchase Agreement, with Vesta Intermediate Funding, Inc., or Vesta, pursuant to which the Company purchased certain assets and obtained a non-exclusive, royalty-free, perpetual, irrevocable, assignable, sublicensable, and worldwide license to certain intellectual property owned by Vesta, or the Vesta Acquisition. The total consideration was $ 19.1 million in cash, $3.2 million and $3.0 million in cash payable on November 7, 2021 and November 7, 2023, respectively, and two contingent share issuances of up to 303,721 shares each, of the Company’s common stock upon the achievement of certain price targets. The transaction, which closed on November 7, 2019, allows the Company to achieve a greater degree of vertical integration, obtaining direct control of breast implant manufacturing and product development activities and generating production-related cost synergies.

~~The~~Prior to the asset acquisition on November 7, 2019, the Company ~~has~~ engaged Vesta ~~Intermediate Funding, Inc., or Vesta, a Lubrizol Lifesciences company,~~ for the manufacture and supply of the Company’s breast implants. On March 14, 2017, the Company announced it had submitted a site-change pre-market approval, or PMA, supplement to the FDA for the manufacture of the Company’s PMA-approved breast implants at the Vesta manufacturing facility. On January 30, 2018, the Company announced the FDA has granted approval of the site-change supplement for the ~~Company’s contract manufacturer, Vesta, to~~ manufacture of its silicone gel breast ~~implants.~~implants at the Vesta manufacturing facility. In support of the move to the Vesta manufacturing facility, the Company also implemented new manufacturing process improvements which, in consultation with the FDA, required three (3) additional PMA submissions. In addition to approving the manufacturing site-change PMA supplement, the FDA approved the Company’s three (3) process enhancement submissions on January 10, 2018, January 19, 2018 and April 17, ~~2018~~.2018.

On May 7, 2018, the Company completed an underwritten follow-on public offering of 7,407,408 shares of its common stock at $13.50 per share, as well as 1,111,111 additional shares of its common stock pursuant to the full exercise of the over-allotment option granted to the underwriters. Net proceeds to the Company were approximately $107.6 million after deducting underwriting discounts and commissions of $6.9 million and offering expenses of approximately $0.5 million.

On June 7, 2019, the Company completed an underwritten follow-on public offering of 17,391,305 shares of its common stock at $5.75 per share, as well as 2,608,695 additional shares of its common stock pursuant to the full exercise of the over-allotment option granted to the underwriters. Net proceeds to the Company were approximately $107.7 million after deducting underwriting discounts and commissions of $6.9 million and offering expenses of approximately $0.4 million.

Further, during the first quarter of 2020, the Company sold 37,000 shares of its common stock under the At-The-Market Equity Offering Sales Agreement with Stifel, Nicolaus & Company, Incorporated which was entered into in February 2018. Net proceeds to the Company after commissions were approximately $0.3 million.

The accompanying unaudited condensed consolidated financial statements in this Quarterly Report on Form 10-Q have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, and the rules and regulations of the U.S. Securities and Exchange Commission, or SEC. Accordingly, they do not include certain footnotes and financial presentations normally required under accounting principles generally accepted in the United States of America for complete financial reporting. The interim financial information is unaudited, but reflects all normal adjustments and accruals which are, in the opinion of management, considered necessary to provide a fair presentation for the interim periods presented. The accompanying condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, ~~2018~~2019 filed with the SEC on March ~~14, 2019,~~16, 2020, or the Annual Report. The results for the three ~~and six~~ months ended ~~June 30, 2019~~March 31, 2020 are not necessarily indicative of results to be expected for the year ending December 31, ~~2019,~~2020, any other interim periods, or any future year or period.

Since the Company’s inception, it has incurred significant net operating losses and the Company anticipates that losses will continue in the near term. ~~The~~Although the Company expects its operating expenses will ~~continue~~begin to ~~grow~~decrease with the implementation of the organizational efficiency initiative announced on November 7, 2019, and other measures introduced as ~~they expand operations. The~~announced in the Company’s filing on Form 8-K on April 7, 2020, the Company will need to generate significant net sales to achieve profitability. To date, the Company has funded operations primarily with proceeds from the sales of preferred stock, borrowings under term loans and convertible note, sales of products since 2012, and the proceeds from the sale of common stock in public offerings.

The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which implies the Company will continue to realize its assets and discharge its liabilities in the normal course of business. As of ~~June 30, 2019,~~March 31, 2020, the Company had cash and cash equivalents of ~~$146.1~~$112.1 million. Since inception, the Company has incurred recurring losses from operations and cash outflows from operating activities. The continuation of the Company as a going concern is dependent upon many factors including liquidity and the ability to raise capital. The Company received FDA approval of ~~their~~its PMA supplement on April 17, 2018 and was then able to access a $10.0 million term loan pursuant to an amendment to the credit agreement with MidCap Financial Trust, or MidCap. In addition, in February 2018, the Company entered into an At-The-Market Equity Offering Sales Agreement with Stifel, Nicolaus & Company, Incorporated, or Stifel, as sales agent pursuant to which the Company may sell, from time to time, through Stifel, shares of our common stock having an aggregate gross offering price of up to $50.0

million. As of ~~June 30, 2019,~~March 31, 2020, the Company has ~~not~~ sold ~~any~~37,000 shares of its common stock pursuant to the sales agreement., resulting in net proceeds after commissions of approximately $0.3 million. Further, on May 7, 2018 and June 7, 2019, the Company completed public offerings of its common stock, raising approximately $107.6 million and $107.7 million, respectively, in net proceeds after deducting underwriting discounts and commissions and other offering expenses.

On July 1, 2019, the Company entered into certain credit agreements with Midcap Financial Trust pursuant to which the Company repaid its existing indebtedness under its Loan Agreement and the outstanding commitment fee was cancelled. On May 11, 2020, the Company amended certain credit agreements with Midcap Financial Trust pursuant to which the Company repaid certain amounts of its existing indebtedness. See Note 1511 – Debt and Note 16 – Subsequent Events for further discussion.

On March 11, 2020, the Company entered into a facility agreement with Deerfield Partners, L.P., issuing $60.0 million in principal amount of 4.0% unsecured and subordinated convertible notes upon the terms and conditions set forth in the facility agreement. See Note 11 – Debt for further discussion.

The Company believes that its cash and cash equivalents will be sufficient to fund its operations for at least the next 12 months. To fund ongoing operating and capital needs, the Company may need to raise additional capital in the future through the sale of equity securities and incremental debt financing.

The preparation of the condensed consolidated financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

In ~~February 2016,~~August 2018, the FASB issued ~~Accounting Standards Update, or~~ ASU ~~2016-02, Leases~~2018-13, Fair Value Measurement (Topic ~~842). This ASU requires a company~~820) - Disclosure Framework - Changes to ~~recognize lease assets~~the Disclosure Requirements for Fair Value Measurement. The amendment modifies, removes, and liabilities arising from operating leases in the statement of financial position. This ASU does not significantly change the previous lease guidance for how a lessee should recognize the recognition, measurement, and presentation of expenses and cash flows arising from a lease. Additionally, the criteria for classifying a finance lease versus an operating lease are substantially the same as the previous guidance. Thisadds certain disclosure requirements on fair value measurements. The ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption was permitted. The Company adopted the applicable amendments within ASU 2018-13 prospectively in the first quarter of 2020 and there was no material impact on its condensed consolidated financial statements from the adoption.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. The amendment aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendment. The ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2019. Early adoption was permitted. The Company adopted ASU 2018-15 prospectively in the first quarter of 2020 and there was no material impact on its condensed consolidated financial statements from the adoption.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848)-Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendment provides optional expedients and exceptions for contract modifications that replace a reference rate affected by reference rate reform. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022, and entities may elect to apply by Topic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. The Company is currently evaluating the impact the election of the optional expedient will have on the consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendment removes certain exceptions for recognizing deferred taxes for investments, performing intraperiod allocation, and calculating income taxes in interim periods. The amendment also adds guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. The ASU is effective for annual and interim periods in fiscal years beginning after December 15, ~~2018, including interim periods within those fiscal years, and early~~2020. Early adoption ~~was~~is permitted. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842) Targeted Improvements, amending certain aspects of the new leasing standard. The amendment allowed an additional optional transition method whereby an entity records a cumulative effect adjustment to opening retained earnings in the year of adoption without restating prior periods. The Company ~~adopted Topic 842 on January 1, 2019 electing~~is currently evaluating the package of practical expedients permitted under the transition guidance, which allowed the Company to carry forward the historical lease classification, the assessment on whether a contract is or contains a lease, and the initial direct costs for any leasesimpact that ~~exist prior to~~ adoption of the new standard. The Company has not restated prior periods under the optional transition method. The adoption of ASU 2016-02 on January 1, 2019 resulted in the recognition of right-of-use assets of approximately $22.7 million, lease liabilities of approximately $22.9 million and no cumulative-effect adjustment on retained earnings on its Condensed Consolidated Balance Sheets. Refer to Note 9 - Leases for further details.

In February 2018, the FASB issued ASU 2018-02, Income Taxes (Topic 740), which allows for an entity to elect to reclassify the income tax effects on items within accumulated other comprehensive income resulting from U.S. Tax Cuts and Jobs Act to retained earnings. The guidance is effective for fiscal years beginning after December 15, 2018 with early adoption permitted, including interim periods within those years. The Company adopted ASC 2018-02 and elected to not reclassify the income tax effects under ASU 2018-02, as it does notstandard will have ~~a material impact~~ on the ~~condensed~~ consolidated financial statements.

On March 11, 2020, the World Health Organization declared the outbreak of a novel strain of coronavirus, also known as COVID-19, a global pandemic. Due to the pandemic, there has been uncertainty and disruption in the global economy and significant volatility of financial markets. The Company is subject to risks and uncertainties as a result of the COVID-19 pandemic. The full extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s business, results of operations and financial condition, including sales, expenses, reserves and allowances, manufacturing, and employee-related amounts, will depend on future developments that are highly uncertain. The Company continues to monitor and assess new information related to the COVID-19 pandemic, the actions taken to contain or treat COVID-19, as well as the economic impact on local, regional, national and international customers and markets.

As an aesthetics company, the Company's products are susceptible to local and national government restrictions, such as social distancing, “shelter in place” orders and business closures, due to the economic and logistical impacts these measures have on consumer demand as well as the practitioners’ ability to administer such procedures. The inability to perform such non-emergency procedures has harmed the Company’s revenues for the period ending March 31, 2020 and will likely result in future harm while these or new restrictions remain in place. In addition, capital markets and economies worldwide have also been negatively impacted by the COVID-19 pandemic, and it is possible that this can lead to a local and/or global economic recession, which may result in further harm to the aesthetics market. Such economic disruption could adversely affect the Company’s business.

The estimates used for, but not limited to, determining the collectability of accounts receivable, fair value of long-lived assets, and goodwill could be impacted by the pandemic. While the full impact of COVID-19 is unknown at this time, the Company has made appropriate estimates based on the facts and circumstances available as of the reporting date. These estimates may change as new events occur and additional information is obtained.

Certain reclassifications have been made to prior year amounts to conform to the current year presentation.

On November 7, 2019, the Company announced an organizational efficiency initiative, or the Plan, designed to reduce spending and simplify operations. Under the Plan, the Company will implement numerous initiatives to reduce spending, including closing the Santa Clara offices of miraDry, Inc. and consolidating a number of business support services via a shared services organization at the Company’s Santa Barbara headquarters.

Under the Plan, the Company intends to reduce its workforce by terminating approximately 70 employees. The Company expects to incur total charges of approximately $4.1 million in connection with one-time employee termination costs, retention costs and other benefits. In addition, the Company expects to incur estimated charges of approximately $0.7 million related to contract termination costs, duplicate operating costs, and other associated costs. In total, the Plan is estimated to cost approximately $4.8 million, excluding non-cash charges, with related cash payments expected to be substantially paid out with cash on hand by the end of 2020.

The following table details the amount of the liabilities related to the Plan included in "Accrued and other current liabilities" in the condensed consolidated balance sheet as of March 31, 2020 (amounts in thousands):

During the three months ended March 31, 2020, the Company recorded $1.7 million of severance and other associated costs related to the Plan. The following table details the charges by reportable segment, recorded in "Restructuring" under operating expenses in the condensed consolidated statements of operations for the three months ended March 31, 2020 by segment (amounts in thousands):

The Company has incurred cumulative restructuring charges of $2.8 million since the commencement of the restructuring plan through March 31, 2020. It is anticipated that the Company will additionally incur approximately $2.0 million of total restructuring costs during the remainder of 2020, of which $0.1 million would be attributable to the Breast Products segment and $1.9 million would be attributable to the miraDry segment. As the development of the Plan is completed, the Company will update its estimated costs by reportable segment as needed.

The Company generates revenue primarily through the sale and delivery of promised goods or services to customers and recognizes revenue when control is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for the goods or services. Performance obligations typically include the delivery of promised products, such as breast implants, tissue expanders, BIOCORNEUM, miraDry Systems and bioTips, along with service-type warranties and deliverables under certain marketing programs. Other deliverables are sometimes promised, but are ancillary and insignificant in the context of the contract as a whole. Sales prices are documented in the executed sales contract, purchase order or order acknowledgement prior to the transfer of control to the customer. Customers may enter into a separate extended service agreement to purchase an extended warranty for miraDry products from the Company whereby the payment is due at the inception of the agreement. Typical payment terms are 30 days for Breast Products and direct sales of consumable miraDry products, and tend to be

longer for capital sales of miraDry Systems and sales to miraDry distributors, but do not extend beyond one year. For delivery of promised products, control transfers and revenue is recognized upon shipment, unless the contractual arrangement requires transfer of control when products reach their destination, for which revenue is recognized once the product arrives at its destination. Revenue for extended service agreements are recognized ratably over the term of the agreements.

For Breast Products, with the exception of the Company’s BIOCORNEUM scar management products, the Company allows for the return of products from customers within six months after the original sale, which is accounted for as variable consideration. Reserves are established for anticipated sales returns based on the expected amount calculated with historical experience, recent gross sales and any notification of pending returns. The estimated sales return is recorded as a reduction of revenue and as a sales return liability in the same period revenue is recognized. Actual sales returns in any future period are inherently uncertain and thus may differ from the estimates. If actual sales returns differ significantly from the estimates, an adjustment to revenue in the current or subsequent period would be recorded. The Company has established an allowance for sales returns of ~~$7.0~~$8.7 million and ~~$6.0~~$8.1 million as of ~~June 30, 2019~~March 31, 2020 and December 31, ~~2018~~2019 respectively, recorded as “sales return liability” on the condensed consolidated balance sheets.

The following table provides a rollforward of the sales return liability (in thousands):

	Sales return liability			Sales return liability
Balance as of December 31, 2018	$	6,048
Balance as of December 31, 2019				$	8,116
Addition to reserve for sales activity		47,178			28,538
Actual returns		(46,895	)		(28,074	)
Change in estimate of sales returns		689			127
Balance as of June 30, 2019	$	7,020
Balance as of March 31, 2020				$	8,707

For Breast Products, a portion of the Company’s revenue is generated from the sale of consigned inventory of breast implants maintained at doctor, hospital, and clinic locations. For these products, revenue is recognized at the time the Company is notified by the customer that the product has been implanted, not when the consigned products are delivered to the customer’s location.

For miraDry, in addition to domestic and international direct sales, the Company leverages a distributor network for selling the miraDry System internationally. The Company recognizes revenue when control of the goods or services is transferred to the distributors. Standard terms in both direct sales agreements (domestic and international), and international distributor agreements do not allow for trial periods, right of return, refunds, payment contingent on obtaining financing or other terms that could impact the customer’s payment obligation.

The Company has determined that the delivery of each unit of product in the Company’s revenue contracts with customers is a separate performance obligation. The Company’s revenue contracts may include multiple products or services, each of which is considered a separate performance obligation. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on observable prices or using an expected cost plus margin approach when an observable price is not available. The Company invoices customers once products are shipped or delivered to customers depending on the negotiated shipping terms.

The Company introduced its Platinum20 Limited Warranty Program, or Platinum20, in May 2018 on all OPUS breast implants implanted in the United States or Puerto Rico on or after May 1, 2018. Platinum20 provides for financial assistance for revision surgeries and no-charge contralateral replacement implants upon the occurrence of certain qualifying events. The Company considers Platinum20 to have an assurance warranty component and a service warranty component. The assurance component is recorded as a warranty liability at the time of sale (as discussed in Note 6)7). The Company considers the service warranty component as an additional performance obligation and defers revenue at the time of sale based on the relative estimated selling price, by estimating a standalone selling price using the expected cost plus margin approach for the performance obligation. Inputs into the

expected cost plus margin approach include historical incidence rates, estimated replacement costs, estimated financial assistance payouts and an estimated margin. The liability for unsatisfied performance obligations under the service warranty as of ~~June 30, 2019~~March 31, 2020 and December 31, ~~2018~~2019 was ~~$0.7~~$1.3 million and ~~$0.4~~$1.2 million, respectively. The short-term obligation related to the service warranty ~~was $0.3 million and $0.2 million~~ as of ~~June 30, 2019~~both March 31, 2020 and December 31, ~~2018, respectively,~~2019 was $0.5 million and is included in “accrued and other current liabilities” on the condensed consolidated balance sheets. The long-term obligation related to the service warranty ~~was $0.4 million and $0.3 million~~ as of ~~June 30, 2019~~March 31, 2020 and December 31, ~~2018,~~2019 was $0.8 million and $0.7 million, respectively, and is included in “warranty reserve and other long-term liabilities” on the condensed consolidated balance sheets. The performance obligation is satisfied at the time that Platinum20 benefits are provided and are expected to be satisfied over the following 63 to 24 month period for financial assistance and 20 years for product replacement. Revenue recognized for the service warranty performance obligations for the three ~~and six~~ months ended ~~June 30, 2019~~March 31, 2020 was immaterial.

The Company generally expenses sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within sales and marketing expenses.

The Company does not adjust accounts receivable for the effects of any significant financing components as customer payment terms are shorter than one year.

The Company has elected to account for shipping and handling activities performed after a customer obtains control of the products as activities to fulfill the promise to transfer the products to the customer. Shipping and handling activities are largely provided to customers free of charge for the Breast Products segment. The associated costs were ~~$0.9~~$0.7 million and ~~$0.6 million for the six months ended June 30, 2019 and 2018 respectively. The associated costs were $0.5 million and $0.3~~$0.4 million for the three months ended ~~June 30,~~March 31, 2020 and 2019, ~~and 2018~~ respectively. These costs are viewed as part of the Company’s sales and marketing programs and are recorded as a component of sales and marketing expense in the condensed consolidated statement of operations as an accounting policy election. For the miraDry segment, shipping and handling charges are typically billed to customers and recorded as revenue. The shipping and handling costs incurred are recorded as a component of cost of goods sold in the condensed consolidated statement of operations. The associated costs were ~~$0.3 million and $0.2~~$0.1 million for ~~the six months ended June 30, 2019 and 2018 respectively. The associated costs were $0.2 million and $0.1 million for~~both the three months ended ~~June 30, 2019~~March 31, 2020 and ~~2018 respectively.~~2019.

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, customer deposits and sales return liability are reasonable estimates of their fair value because of the short maturity of these items. The fair value of the common stock warrant liability, ~~and~~ contingent consideration, and the convertible feature related to the convertible note are discussed in Note 5.6. The fair value of ~~the~~ debt is based on the amount of future cash flows associated with the instrument discounted using the Company’s estimated market rate. As of ~~June 30, 2019,~~March 31, 2020, the carrying value of the long-term debt and convertible note was not materially different from the fair value.

Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.

Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

The Company’s common stock warrant liabilities are carried at fair value determined according to the fair value hierarchy described above. The Company has utilized an option pricing valuation model to determine the fair value of its outstanding common stock warrant liabilities. The inputs to the model include fair value of the common stock related to the warrant, exercise price of the warrant, expected term, expected volatility, risk-free interest rate and dividend yield. The warrants are valued using the fair value of common stock as of the measurement date. The Company ~~historically has been a private company and lacks~~estimates its expected stock volatility based on company-specific historical and implied volatility information of its stock. ~~Therefore, it estimates its expected stock volatility based on the historical volatility of publicly traded peer companies for a term equal to the remaining contractual term of the warrants.~~ The risk-free interest rate is determined by reference to the U.S. Treasury yield curve for time periods approximately equal to the remaining contractual term of the warrants. The Company has estimated a 0% dividend yield based on the expected dividend yield and the fact that the Company has never paid or declared dividends. As ~~several significant inputs are not observable,~~of March 31, 2020, the ~~overall~~ fair value ~~measurement~~ of the warrants ~~is classified~~was immaterial as ~~Level 3.~~a result of the decline in the Company’s stock price.

The Company assessed the fair value of the contingent consideration for future royalty payments related to the acquisition of BIOCORNEUM and the contingent consideration for the future milestone payments related to the acquisition of miraDry using a Monte-Carlo simulation model. ~~Significant assumptions used in~~The contingent consideration related to the ~~measurement include~~acquisition of BIOCORNEUM consist of royalty obligations based on future net sales for a defined term, ~~and~~beginning in 2024. The significant assumption utilized in the ~~risk-adjusted~~fair value measurement was the revenue discount rate, ~~associated with~~which was 19.0%. The contingent consideration for future milestone payments related to the ~~business.~~acquisition of miraDry is based on the timing of achievement of target net sales, which is estimated based on an internal management forecast. The significant assumption utilized in the fair value measurement was the miraDry company discount rate, which was 11.2%. As ~~the~~these inputs are not observable, the overall fair value measurement of the contingent consideration is classified as Level 3. During the quarter ended March 31, 2020, there were no material changes to the fair value of the contingent consideration.

The Company assessed the fair value of the conversion feature related to the convertible note due in 2025. The conversion feature was bifurcated and recorded as a current derivative liability on the condensed consolidated balance sheet with a corresponding discount at the date of issuance that is netted against the principal amount of the note. The Company has utilized a binomial lattice method to determine the fair value of the conversion feature, which utilizes inputs including the common stock price, volatility of common stock, the risk-free interest rate and the probability of conversion to common shares at the Base Conversion Rate and in the event of a major transaction (e.g. a change in control). As the probability of conversion is a significant unobservable input, the overall fair value measurement of the conversion feature is classified as level 3.

The following tables present information about the Company’s liabilities that are measured at fair value on a recurring basis as of ~~June 30, 2019~~March 31, 2020 and December 31, ~~2018~~2019 and indicate the level of the fair value hierarchy utilized to determine such fair value (in thousands):

The Company offers a product replacement and limited warranty program for the Company’s silicone gel breast implants, and a product warranty for the Company’s miraDry Systems and consumable bioTips. For silicone gel breast implant surgeries occurring prior to May 1, 2018, the Company provides lifetime replacement implants and up to $3,600 in financial assistance for revision surgeries, for covered rupture events that occur within ten years of the surgery date. The Company introduced its Platinum20 Limited Warranty Program in May 2018, covering OPUS silicone gel breast implants implanted in the United States or Puerto Rico on or after May 1, 2018. The Company considers the program to have an assurance warranty component and a service warranty component. The service warranty component is discussed in Note 34 above. The assurance component is related to the lifetime no-charge contralateral replacement implants and up to $5,000 in financial assistance for revision surgeries, for covered rupture events that occur within twenty years of the surgery date. Under the miraDry warranty, the Company provides a standard product warranty for the miraDry System and bioTips, which the Company considers an assurance-type warranty.

Basic net loss per share attributable to common stockholders is computed by dividing net loss by the weighted average number of common shares outstanding during each period. Diluted net loss per common share is computed by dividing net loss available to common stockholders by the weighted average number of common shares and dilutive potential common share equivalents then outstanding, to the extent they are dilutive. Potential common shares consist of shares issuable upon the exercise of stock options and warrants (using the treasury stock method). Dilutive net loss per share is the same as basic net loss per share for all periods presented because the effects of potentially dilutive items were anti-dilutive.

The Company uses the if-converted method for calculating any potential dilutive effects of the convertible note. The Company did not adjust the net loss for the quarter ended March 31, 2020 to eliminate any interest expense or gain/loss for the derivative liability related to the note in the computation of diluted loss per share, as the effects would be anti-dilutive. Further, the Company excluded from diluted weighted average shares approximately 14.6 million shares issuable upon conversion for the quarter ended March 31, 2020, as the effects would be anti-dilutive.

The Company has established an allowance for doubtful accounts of $3.2 million and $2.4 million as of June 30, 2019 and December 31, 2018, respectively, recorded net against accounts receivable in the balance sheet.

Depreciation expense for ~~both~~ the three months ended ~~June 30,~~March 31, 2020 and 2019 was $0.7 million and ~~2018 was~~ $0.3 ~~million. Depreciation expense for both the six months ended June 30, 2019 and 2018 was $0.6 million.~~million, respectively.

Under the terms of the manufacturing agreement with Vesta, upon the commencement of Contract Year One (as defined in the agreement) which occurred following FDA-approval of all submissions related to the site-change PMA supplement for the Vesta manufacturing facility, Vesta was obligated to purchase the manufacturing equipment and tooling that Sientra had originally purchased for the manufacture of Sientra’s breast implant inventory at Vesta’s manufacturing facility. Vesta repurchased the equipment with a net book value of $2.7 million in the third quarter of 2018 through a reduction in the Company’s accounts payable balance owed to Vesta.

The Company has determined that it has two reporting units, Breast Products and miraDry, and evaluates goodwill for impairment at least annually on October 1^st and whenever circumstances suggest that goodwill may be impaired. ~~As of June 30, 2019 and December 31, 2018 the miraDry reporting unit had a negative carrying value.~~

The changes in the carrying amount of goodwill during the ~~six~~three months ended ~~June 30,~~March 31, 2020 and the year ended December 31, 2019 were as follows (in thousands):

In the ~~second~~first quarter of ~~2019,~~2020, the Company noted a decline in actual and forecasted earnings for the miraDry reporting unit ~~in comparison~~due to ~~forecasted earnings determined in prior periods. Based on this evaluation,~~ the ~~Company determined that~~effects and uncertainty surrounding the ~~carrying value of the miraDry reporting unit more likely than not exceeded its estimated fair value.~~COVID-19 pandemic. As a result, the Company performed a ~~quantitative analysis to compare~~test of recoverability by comparing the ~~fair~~carrying value of the reporting unit ~~to its carrying amount.~~

The Company’s fair value analysis of goodwill utilizes the income approach, which requires the use of estimates about a reporting unit’s future revenues and free cash flows, discount rates, terminal value and enterprise value to determine the estimated fair value. The Company’s future revenues and free cash flow assumptions are determined based upon actual results giving effect to management’s expected changes in operating results in future years. The enterprise value, discount rates and terminal value are based upon market participant assumptions using a defined peer group.

After performing the impairment test as of June 30, 2019 the Company determined that the carrying value of its miraDry reporting unit exceeded its estimated fair value using the income approach, as described above, by an amount that indicated a full impairment of the carrying value of goodwill. Consequently, the Company recorded a non-cash goodwill impairment charge of $7.6 million in the accompanying condensed consolidated statement of operations for the three and six months ended June 30, 2019.

~~The components of the Company’s other intangible assets consist of the following (in thousands):~~

In connection with the circumstances leading to the impairment of goodwill for the miraDry reporting unit, the Company performed a test of recoverability of the intangible assets in the miraDry reporting unit by comparing the carrying amount of the intangible assets to the future undiscounted cash flows the ~~assets are~~reporting unit is expected to generate. As the future undiscounted cash flows attributable to the ~~intangible assets~~asset group were less than the carrying value, the Company performed a quantitative analysis to compare the fair value of the intangible assets in the reporting unit to their carrying amount.

The Company’s fair value analysis of intangible assets utilizes methods under various income approaches. The Company values its customer relationships using an excess earnings method, which assumes the value of the asset is the discounted ~~cash flow using estimates of~~ future cash ~~flow~~flows derived from existing ~~customers. Similarly, distributor relationships~~customers and requires the use of customer attrition rates and discount rates to determine the estimated fair value. The future revenues and free cash flow from existing customers are ~~valued~~determined based upon actual results giving effect to management’s expected changes in operating results in future years. The attrition rate is based on average historical levels of customer attrition and the discount rate is based upon market participant assumptions using a ~~distributor method, which assumes the value of the asset is the discounted cash flow using estimates of future cash flow derived from existing distributors.~~defined peer group. Tradenames and developed technology are valued using a relief from royalty method, which assumes the value of the asset is the discounted cash flows of the amount that would be paid by a hypothetical market participant had they not owned the asset and instead licensed the asset from another company. This method requires the use of royalty rates which are determined based on comparable third party license agreements involving similar assets and discount rates similar to the above to determine the estimated fair value.

After performing the impairment ~~test~~analysis as of ~~June 30, 2019,~~March 31, 2020, the Company determined that the carrying values of all of the intangible assets in the miraDry reporting unit exceeded their estimated fair values. Consequently, the Company recorded total non-cash impairment charges of ~~$0.4~~$1.1 million for trade names, $1.4 million for developed technology, and $3.9 million for customer relationships ~~$0.3 million for distributor relationships, $3.3 million for tradenames, and $1.0 million for developed technology~~ within ~~goodwill and other intangible~~ impairment in the accompanying condensed consolidated statement of operations for the ~~three and six months~~quarter ended ~~June 30, 2019.~~March 31, 2020. As March 31, 2020, the remaining carrying value of the intangible assets are entirely associated with the Breast Products segment.

~~Intangibles amortization~~The components of the Company’s other intangible assets consist of the following (in thousands):

Amortization expense for ~~both~~ the three months ended ~~June 30,~~March 31, 2020 and 2019 ~~and 2018~~ was $0.6 ~~million. Intangibles amortization expense for both the six months ended June 30, 2019 and 2018 was $1.2~~ million.

The Company leases certain office space, warehouses, distribution facilities and office equipment. ~~The Company also has embedded leases of manufacturing facilities and equipment associated with the Company’s manufacturing contracts.~~ The Company determines if an arrangement contains a lease at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether the Company obtains substantially all of the economic benefits from and has the ability to direct the use of the asset.

Operating and finance lease right-of-use, or ROU, assets and lease liabilities are recognized based on the present value of the future lease payments over the lease term at the commencement date. The Company determines its incremental borrowing rate based on the information available at the commencement date in determining the lease liabilities as the Company’s leases generally do not provide an implicit rate. The ROU assets also include any initial direct costs incurred and any lease payments made at or before the lease commencement date, less lease incentives received. Lease terms may include options to extend or terminate when the Company is reasonably certain that the option will be exercised. As of June 30, 2019, the Company has included a five-year renewal option in the lease term for one operating lease as it was concluded that it is reasonably certain that the Company will exercise the option. The Company elected to apply the short-term lease measurement and recognition exemption in which ROU assets and lease liabilities are not recognized for short-term leases. The Company’s lease agreements generally do not contain material residual value guarantees or material restrictive covenants.

The Company’s leases of office space, warehouses and distribution facilities are treated as operating leases and often contain lease and non-lease components. The Company has elected to account for these lease and non-lease components separately. Non-lease components for these assets are primarily comprised of common-area maintenance, utilities, and real estate taxes that are passed on from the lessor in proportion to the space leased by the Company, and are recognized in operating expenses in the period in which the obligation for those payments was incurred. Lease cost for these operating leases is recognized on a straight-line basis over the lease term in operating expenses.

The Company’s embedded leases of manufacturing facilities and equipment are treated as operating leases and often contain lease and non-lease components. The Company has elected to account for these lease and non-lease components as a single lease component. There may be variability in future lease payments as the amount of the non-lease components is based on the costs of manufacturing and is dependent on the amount and types of units produced. The Company reduces the operating lease liability when the inventory is purchased.

The Company’s leases of office equipment are accounted for as finance leases as they meet one or more of the five finance lease classification criteria. Lease cost for these finance leases is comprised of amortization of the ROU asset and interest expense which are recognized in operating expenses and other income (expense), net.

As previously reported in our Annual Report on Form 10-K for the year ended December 31, 2018 and under legacy lease accounting (ASC 840), future minimum lease payments under non-cancellable leases as of December 31, 2018 was as follows (in thousands):

The table above does not include the minimum purchase obligations of approximately $21.6 million over the five years following December 31, 2018 under the Company’s contracts with its manufacturers which upon adoption of ASU 2016-02 on January 1, 2019 were accounted for as operating lease ROU assets and lease liabilities.

On July 25, 2017, the Company entered into a Credit and Security Agreement, or the Existing Term Loan Credit Agreement, and a Credit and Security Agreement, or the Existing Revolving Credit Agreement with MidCap ~~and, together with the Term Loan Credit Agreement, the Credit Agreements,~~Financial Trust, which replaced the Company’s ~~then-existing~~prior Silicon Valley Bank Loan Agreement, or the SVB Loan Agreement.

~~Under~~ On July 1, 2019 the ~~terms of the~~Company entered into a Restated Term Loan Credit Agreement with MidCap Financial Trust as ofthe agent and lender, and additional lenders thereto from time to time, or the Restated Term Loan Agreement, which restated the Existing Term Loan Agreement.

MidCap also made available~~Loan Agreement, the Credit Agreements, which restated the Existing Revolving Credit Agreement.

The Restated Term Loan Agreement provided for (i) a $35 million term loan facility drawn at signing, (ii) a $5 million term loan facility drawn at signing, (iii) at any time after September 30, 2020 to ~~the Company until March~~December 31, ~~2018,~~2020, a $10.0 million term loan ~~or the March 2018 Term Loan, subject to the satisfaction of certain conditions, including FDA certifications of the manufacturing~~ facility ~~operated by Vesta, and an additional $5.0 million term loan, subject~~(subject to the satisfaction of certain conditions, including evidence that the Company’s Net Revenue for the past 12 months was greater than or equal to ~~$75.0~~$100.0 million), and (iv) until December 31, 2020 and upon the consent of Agent and the lenders following a request from the Company, an additional $15.0 million ~~as defined in~~term loan facility, or altogether, the Restated Term Loan. The Restated Term Loan ~~Credit Agreement, collectively~~matures on July 1, 2024 and carries an interest rate of LIBOR plus 7.50%. The Company will make monthly payments of accrued interest under the Restated Term Loan from the funding date of the Restated Term Loan, until July 31, 2021, to be followed by monthly installments of principal and interest through the Maturity Date of July 1, 2024. The Company may prepay some or all of the Restated Term Loan prior to its maturity date provided the Company pays MidCap a prepayment fee. Net proceeds from the Restated Term Loan were used to repay the $35 million outstanding balance related to the Term Loans. ~~On April 18, 2018,~~As of March 31, 2020, there was $40.0 million outstanding related to the Restated Term Loans of which $25.0 million is presented in “Current portion of long-term debt” and $15 million is presented in “Long-term debt, net of current portion” on the condensed consolidated balance sheet as a result of the Company entering into the Second Amendment to Amended and Restated Credit and Security Agreement, by and among the Company, ~~amended the Term Loan Credit Agreement pursuant to which the~~ parties agreed to adjust the date by which the Company must obtain FDA approval of its PMA supplement in order to access the March 2018 Term Loan until April 30, 2018.

Refer to Note 16 – Subsequent Events for further detail on the Debt Restructuring. As of March 31, 2020, the unamortized debt issuance costs on the Restated Term Loans was $1.6 million ~~March Term Loan.~~and are included as a reduction to debt in “Long-term debt, net of current portion” on the condensed consolidated balance sheet. ~~Under the~~

The Restated Revolving Credit Agreement ~~MidCap made available to the Company~~provides for, among other things, a revolving ~~line~~loan of ~~credit, or the~~up to $10.0 million (the “Restated Revolving ~~Loan.~~Loan”). The amount of loans available to be drawn under the Revolving Credit Agreement is based on a borrowing base equal to 85% of the net collectible value of eligible accounts receivable plus 40% of eligible finished goods inventory, or the Borrowing Base, provided that availability from eligible finished goods inventory does not exceed 20% of the Borrowing Base. The ~~Company used a portion~~Restated Revolving Loan carries an interest rate of the $25.0 million of proceeds from the Closing Date Term Loan to repay in full the Company’s then-existing indebtedness under its SVB Loan Agreement and to pay fees and expenses in connection with the foregoing and the Company intends to use the remainder of the proceeds for general corporate purposes.

~~Any indebtedness under the Term Loan Credit Agreement bears interest at a floating per annum rate equal to the~~ LIBOR as reported by MidCap with a floor of 1.00%, which as of June 30, 2019 was 2.44%, plus 7.50%. The Term Loans have a scheduled maturity date of December 1, 2021, or the Maturity Date. Subject to an election to delay principal payments, the Company made monthly payments of accrued interest under the Term Loans from the funding date of the Term Loans, until December 31, 2018, to be followed by monthly installments of principal and interest through the Maturity Date. Under the terms of the Term Loan Credit Agreement, the Company had the option to extend the interest only period an additional six months to June 30, 2019 as long as the Company remained in compliance with the Term Loan Agreement. The Company has elected to extend the interest only period through June 30, 2019. The Company may prepay all of the Term Loans prior to its maturity date provided the Company pays MidCap a prepayment fee. The Company paid an origination fee of 0.50% of the Term Loans total amount of $40.0 million on the closing date. As of June 30, 2019, there was $35.0 million outstanding related to the Term Loans. As of June 30, 2019, the unamortized debt issuance costs on the Term Loans was approximately $0.1 million current portion and approximately $0.1 million long-term portion and are included as a reduction to debt on the condensed consolidated balance sheet.

On May 11, 2020, in association with the Debt Restructuring, the Company entered in to the Second Amendment to Amended and Restated Credit and Security Agreement (Revolving Loan), by and among the Company, certain of the Company’s subsidiaries, the lenders party thereto and MidCap Financial Trust as agent (the “Revolving Amendment”). Refer to Note 16 – Subsequent Events for further detail on the Debt Restructuring.

The amortization of debt issuance costs on the Restated Term Loans and the Restated Revolving Loan for the three months ended ~~June 30,~~March 31, 2020 and 2019 ~~and 2018 was $43,000 and $34,000, respectively. The amortization of debt issuance costs for both the six months ended June 30, 2019 and 2018 was~~were $0.1 million, and was included in interest expense in the condensed consolidated statements of operations.

The Credit Agreements include customary affirmative and restrictive covenants and representations and warranties, including a financial covenant for minimum revenues, a financial covenant for minimum cash requirements, a covenant against the occurrence of a “change in control,” financial reporting obligations, and certain limitations on indebtedness, liens, investments, distributions, collateral, mergers or acquisitions, taxes, and deposit accounts. Upon the occurrence of an event of default, a default interest rate of an additional 5.0% may be applied to any outstanding principal balances, and MidCap may declare all outstanding obligations immediately due and payable and take such other actions as set forth in the Credit Agreements. The Company’s obligations under the Credit Agreements are secured by a security interest in substantially all of ~~The~~the Company’s assets.

On March 11, 2020, the Company issued $60.0 million of unsecured and subordinated convertible notes with an interest rate of 4.00% (“Note”) to Deerfield Partners, L.P. (“Holder”) in order to fund ongoing operations. The Note matures on March 11, 2025, subject to earlier conversion by the option of the Holder at any time in whole or in part into common shares of the Company, for a period up to five years. Upon conversion by the Holder, the Company shall deliver, shares of the Company’s common stock at a conversion rate of 14,634 per $1,000 principal amount of the Note (which represents an initial conversion rate price of $4.10), or the Base Conversion Rate, in each case subject to customary anti-dilution adjustments. In addition to the typical anti-dilution adjustment, the Note also provides the Holder with additional consideration (“Make-Whole Provision”) beyond the settlement of the conversion obligation, in the event of a major transaction prior to maturity (e.g. a change in control). Upon conversion by the Holder in the event of a major transaction, the Company shall deliver, either cash, shares of the Company’s common stock or a combination of cash and common stock at the Base Conversion rate plus the additional consideration from the Make-Whole Provision. The $60.0 million principal amount of the Note is not payable until the maturity date of March 11, 2025, unless converted to equity earlier. The Company will pay interest in cash on the Note at 4.00% per annum, quarterly from July 1, 2020.

The conversion features in the outstanding convertible debt instrument are accounted for as a free-standing embedded derivative bifurcated from the principal balance of the Note, as (1) the conversion features are not clearly and closely related to the debt instrument and are not considered to be indexed to the Company’s equity, (2) the conversion features standing alone meet the definition of a derivative, and (3) the Note is not remeasured at fair value each reporting period with changes in fair value recorded in the condensed consolidated statement of operations.

The initial embedded derivative liability of $16.1 million was recorded as a non-current liability on the condensed consolidated balance sheet and is remeasured to fair value at each balance sheet date with a resulting non-cash gain or loss related to the change in the fair value being charged to earnings (loss). As of March 31, 2020, the fair value of the derivative liability was $16.2 million. A corresponding debt discount of $16.1 million and issuance costs of $1.5 million were recorded on the issuance date and is netted against the principal amount of the Note. As of March 31, 2020, the unamortized debt discount and issuance costs were $17.5 million. The Company will amortize the debt discount and debt issuance costs to interest expense under the effective interest method over the term of the Note, at a resulting effective interest rate of approximately 12%. For the quarter ended March 31, 2020, the amortization of the convertible debt discount and issuance costs were $0.2 million and were included in interest expense in the condensed consolidated statements of operations. The accrued interest on the outstanding principal amount of $60 million as of March 31, 2020 was $0.1 million and was included in “Accrued and other current liabilities” in the condensed consolidated balance sheet.

The future schedule of principal payments for ~~the~~all outstanding ~~Term Loans~~debt as of ~~June 30, 2019~~March 31, 2020 was as follows (in thousands):

We are a medical aesthetics company committed to making a difference in patients’ lives by enhancing their body image, growing their ~~self~~ self‑esteem and restoring their confidence. We were founded to provide greater choices to ~~board~~ board‑certified plastic surgeons and patients in need of medical aesthetics products. We have developed a broad portfolio of products with technologically differentiated characteristics, supported by independent laboratory testing and strong clinical trial outcomes. We sell our breast implants ~~and tissue expanders~~for augmentation procedures exclusively to ~~board~~ board‑certified and ~~board~~ board‑admissible plastic surgeons and tailor our customer service offerings to their specific needs, which we believe helps secure their loyalty and confidence. We sell our breast tissue expanders for reconstruction procedures predominantly to hospitals and surgery centers, and our BIOCORNEUM scar management products to plastic surgeons, dermatologists and other specialties.

On June 11, 2017, we entered into a Merger Agreement with miraDry (formerly Miramar Labs) pursuant to which we commenced a tender offer to purchase all of the outstanding shares of miraDry’s common stock. Pursuant to the transaction, which closed on July 25, 2017 we added the miraDry System, the only ~~FDA cleared~~FDA-cleared device to reduce underarm sweat, odor and hair of all colors to our aesthetics portfolio. Following our acquisition of miraDry in July 2017, we began selling the miraDry System, consisting of a console and a handheld device, and consumable single-use bioTips. As a result of the miraDry acquisition, we determined that we ~~will~~ conduct our business in two operating segments: Breast Products and miraDry. The Breast Products segment focuses on sales of our breast implants, tissue expanders and scar management products under the brands ~~OPUS,~~Sientra, AlloX2, Dermaspan, Softspan and BIOCORNEUM. The miraDry segment focuses on sales of the miraDry System, ~~consisting of a console~~ and ~~a handheld device which uses consumable single-use~~ bioTips.

We sell both our Breast Products and miraDry products in the U.S. through a direct sales organization, which as of ~~June 30, 2019,~~March 31, 2020, consisted of ~~105~~93 employees, including 9078 sales representatives and 15 sales managers. Additionally, we also sell our miraDry System in several international markets where we leverage a combination of distributor relationships and direct sales efforts. As of ~~June 30, 2019~~March 31, 2020, our international operations were supported by 67 sales representatives and 43 sales managers, as well as a number of consultants supporting both direct sales efforts and ~~distributer~~distributor relationships.

On March 11, 2020, the World Health Organization declared the outbreak of a novel strain of coronavirus, also known as COVID-19, a global pandemic. Due to the pandemic, there has been uncertainty and disruption in the global economy and significant volatility of financial markets. We are subject to risks and uncertainties as a result of the COVID-19 pandemic. The full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition, including sales, expenses, reserves and allowances, manufacturing, and employee-related amounts, will depend on future developments that are highly uncertain. We continue to monitor and assess new information related to the COVID-19 pandemic, the actions taken to contain or treat COVID-19, as well as the economic impact on local, regional, national and international customers and markets.

As an aesthetics company, our breast and miraDry products are susceptible to local and national government restrictions, such as social distancing, “shelter in place” orders and business closures, due to the economic and logistical impacts these measures have on consumer demand as well as the practitioners’ ability to administer such procedures. The inability to perform such non-emergency procedures has harmed our revenues for the period ending March 31, 2020 and will likely result in future harm while these or new restrictions remain in place. In addition, capital markets and economies worldwide have also been negatively impacted by the COVID-19 pandemic, and it is possible that this can lead to a local and/or global economic recession, which may result in further harm to the aesthetics market. Such economic disruption could adversely affect our business.

The estimates used for, but not limited to, determining the collectability of accounts receivable, fair value of long-lived assets, and goodwill could be impacted by the pandemic. While the full impact of COVID-19 is unknown at this time, we have made appropriate estimates based on the facts and circumstances available as of the reporting date. These estimates may change as new events occur and additional information is obtained. See additional information below regarding the allowance for credit losses for accounts receivable.

In April 2020, in part as a result of the impact of COVID-19, we re-focused our miraDry business to drive high margin, bioTip utilization to our existing installed base. We expect that the net sales we generate from our bioTips will represent high margin sales (on a gross margin basis) and account for a substantial amount of our net sales for the next several years, with high margin consumables comprising a sizable percentage of our miraDry segment’s net sales.

On November 7, 2019, we announced an organizational efficiency initiative, or the Plan, designed to reduce spending and simplify operations. Under the Plan, we will implement numerous initiatives to reduce spending, including closing the Santa Clara offices of miraDry, Inc. and consolidating a number of business support services via a shared services organization at our Santa Barbara headquarters.

Under the Plan, we intend to reduce our workforce by terminating approximately 70 employees. As a result, we expect to incur total charges of approximately $4.1 million in connection with one-time employee termination costs, retention costs and other benefits. In addition, we expect to incur estimated charges of approximately $0.7 million related to contract termination costs, duplicate operating costs, and other associated costs. In total, the Plan is estimated to cost approximately $4.8 million, excluding non-cash charges, with related cash payments expected to be substantially paid out with cash on hand by the end of 2020.

During the three months ended March 31, 2020, we recorded $1.7 million of severance and other associated costs related to the Plan. The following table details the charges by reportable segment, recorded in "Restructuring" under operating expenses in the condensed consolidated statements of operations for the three months ended March 31, 2020 by segment (amounts in thousands):

We have incurred cumulative restructuring charges of $2.8 million since the commencement of the restructuring plan through March 31, 2020. It is anticipated that we will additionally incur approximately $2.0 million of total restructuring costs during 2020, of which $0.1 million would be attributable to the Breast Products segment and $1.9 million would be attributable to the miraDry segment. We expect to realize cost savings of approximately $10.0 million in 2020 and approximately $5.0 million in 2021. All of the 2020 cost savings are expected to be realized in operating expenses, and the 2021 cost savings are expected to be realized approximately 20% in operating expenses and 80% in cost of goods sold. Savings in operating expenses are expected to result from the reduction of headcount through a shared services organization. Savings in cost of goods sold are expected to result from the elimination of manufacturing roles at miraDry. As the development of the Plan is completed, we will update the estimated costs and cost savings as needed.

Our Breast Products segment net sales include sales of silicone gel breast implants, tissue expanders and BIOCORNEUM. We recognize revenue on breast implants and tissue expanders, net of sales discounts and estimated returns, as the customer has a standard six-month window to return purchased breast implants and tissue expanders. We defer the value of our service warranty revenue and recognize it once all performance obligations have been met.

Our miraDry segment net sales include sales of the miraDry System and consumable bioTips along with service warranties and deliverables under certain marketing programs. We recognize revenue on miraDry Systems and bioTips on delivery to the customer. We defer the value of our service warranty and deliverables under certain marketing programs and recognize it over the term of the service warranty contract for service warranties and once all performance obligations have been met for deliverables under certain marketing programs.

We expect that, in the future, our net sales will fluctuate on a quarterly basis due to a variety of factors, including seasonality of breast augmentation procedures, the impact of the pandemic, and purchase of miraDry procedures. We believe that aesthetic procedures are subject to seasonal fluctuation due to patients planning their procedures leading up to the summer season and in the period around the winter holiday season.

Cost of goods sold consists primarily of costs of finished products purchased from our third‑party manufacturers, reserve for product assurance warranties, royalty costs, and warehouse and other related costs. For miraDry, cost of goods sold also consists of raw material, labor, overhead, and variable manufacturing costs, ~~associated with the manufacturing of the miraDry Systems~~reserve for product assurance warranties, royalty costs, excess and ~~bioTips.~~obsolete inventory reserves, and warehouse and other related costs.

With respect to our supplier contracts, all our products and raw materials are manufactured under contracts with fixed unit ~~costs.~~costs which can increase over time at specified amounts.

Under our Breast Products segment, we provide an assurance and service warranty on our silicone gel breast implants. Under our miraDry segment, we provide an assurance and service warranty on our miraDry Systems, and an assurance warranty on our handpieces and bioTips. The estimated warranty costs are recorded at the time of sale. Costs related to our service warranty are recorded when expense is incurred related to meeting our performance obligations. In addition, the inventory fair market value associated with purchase accounting adjustments and royalty costs related to ~~both~~ the SSP and miraDry acquisitions ~~were~~are recorded at the time of sale.

We expect our overall gross margin, which is calculated as net sales less cost of goods sold for a given period divided by net sales, to fluctuate in future periods primarily as a result of quantity of units sold, manufacturing price increases, the changing mix of products sold with different gross margins, warranty costs, overhead costs and targeted pricing programs.

Our sales and marketing expenses primarily consist of salaries, bonuses, benefits, incentive compensation, stock-based compensation, digital marketing, and travel for our sales, marketing and customer support personnel. Our sales and marketing expenses also include expenses for trade shows, our no‑charge customer shipping program for the Breast Products segment and no-charge product evaluation units for the Breast Products segment, as well as educational, promotional and marketing activities, including direct and online marketing. We expect our sales and marketing expenses to fluctuate in future periods as a result of headcount and timing of our marketing programs. ~~However, we generally expect these costs will increase in absolute dollars.~~

Our research and development, or R&D, expenses primarily consist of clinical expenses, product development costs, regulatory expenses, consulting services, outside research activities, quality control and other costs associated with the development of our products and compliance with Good Clinical Practices, or cGCP, requirements. R&D expenses also include related personnel and consultant compensation and stock‑based compensation expense. We expense R&D costs as they are incurred.

We expect our R&D expenses to vary as different development projects are initiated, including improvements to our existing products, expansions of our existing product lines, new product acquisitions and our clinical studies. ~~However, we generally expect these costs will increase in absolute terms over time as we continue to expand our product portfolio and add related personnel.~~

Our general and administrative, or G&A, expenses primarily consist of salaries, bonuses, benefits, incentive compensation and stock-based compensation for our executive, financial, legal, business development and administrative functions. Other G&A expenses include contingent consideration fair market value adjustments, outside legal counsel and litigation expenses, independent auditors and other outside consultants, corporate insurance, facilities and information technologies expenses.

We expect future G&A expenses to ~~increase~~decrease as we ~~continue to build our finance, legal, information technology, human resources and other general administration resources to continue to advance~~implement the ~~commercialization of our products. In addition,~~organizational efficiency initiative, but we also expect to continue to incur G&A expenses in connection with operating as a public company.

Other income (expense), net primarily consists of interest income, interest expense, changes in the fair value of common stock warrants and amortization of issuance costs associated with our Credit Agreements.

Income tax expense consists of an estimate for income taxes based on the projected income tax expense for the period. We operate in several tax jurisdictions and are subject to taxes in each jurisdiction in which we conduct business. To date, we have incurred cumulative net losses and maintain a full valuation allowance on our net deferred tax assets due to the uncertainty surrounding realization of such assets.

The preparation of our unaudited condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and the revenues and expenses incurred during the reported periods. We base our estimates on 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 apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We discussed accounting policies and assumptions that involve a higher degree of judgment and complexity in Note 2 of the “Notes to Financial Statements” in our audited financial statements included in the Annual Report. There have been no material changes to our critical accounting policies and estimates from those disclosed in the Annual ~~Report, other than the implementation of ASU 2016-02 (Topic 842) Leases, as discussed in Note 2 of the unaudited condensed consolidated financial statements included in this Form 10-Q.~~Report.

Please refer to Note 2 - Summary of Significant Accounting Policies in the notes to the unaudited condensed consolidated financial statements included in this Form 10-Q for information on recent accounting pronouncements and the expected impact on our unaudited condensed consolidated financial statements.

Net sales of our miraDry segment was ~~$9.3~~$4.5 million, ~~an increase~~a decrease of ~~$1.2~~$3.3 million, as compared ~~to $8.1 million for the three months ended June 30, 2018, driven primarily by an increase in the volume of sales of miraDry consoles and consumable bioTips in the US and internationally.~~

As of June 30, 2019, our U.S. sales organization included 90 sales representatives as compared to 77 sales representatives as of June 30, 2018. The increase is primarily attributed to headcount increases of both miraDry and Sientra sales representatives as a result of our growth strategy to increase net sales.

~~Cost of goods sold increased $1.2 million, or 17.3%,~~ to $7.8 million for the three months ended ~~June 30,~~March 31, 2019, resulting from an overall decrease in the volume of sales of miraDry systems and consumable bioTips due to the effects of the COVID-19 pandemic.

As of March 31, 2020, our U.S. sales organization included 78 sales representatives as compared to ~~$6.7~~89 sales representatives as of March 31, 2019. The decrease is primarily attributed to an overall decrease in sales headcount implemented under the organizational efficiency initiative.

Cost of goods sold increased $0.3 million, or 4.9%, to $6.8 million for the three months ended ~~June 30, 2018.~~March 31, 2020 as compared to $6.5 million for the three months ended March 31, 2019.

The gross margins for the three months ended ~~June 30,~~March 31, 2020 and 2019 were 59.9% and ~~2018 were 61.9% and 62.1%~~63.1%, respectively. The ~~slight~~ decrease ~~is primarily~~was due to ~~an increase in the~~increased unit ~~cost~~costs of ~~goods sold for the~~ Breast Products ~~segment partially offset by increased~~inventory coupled with lower sales of ~~consumable bioTips in the~~ miraDry ~~reporting unit~~consumables which carry a higher ~~margins.~~margin.

The ~~increase~~decrease is primarily related to ~~an increase~~a decrease in consulting expenses, employee payroll related expenses, legal expenses and ~~bad debt expense, offset by a decrease in~~ contingent consideration fair value adjustments, ~~and stock-based compensation expense.~~offset by an increase in accounting fees.

~~Goodwill and other intangible impairment~~Restructuring expenses ~~increased $12.7 million~~ for the three months ended ~~June 30, 2019 as compared to $0.0~~March 31, 2020 were $1.7 million, consisting primarily of severance expenses of employees affected by the organizational efficiency initiative.

Intangible impairment expenses were $6.4 million for ~~the~~ three months ended ~~June 30, 2018. The increase was~~March 31, 2020, due to impairments of ~~goodwill and~~ intangible assets in the miraDry reporting unit.

Other income (expense), net for the three months ended ~~June 30,~~March 31, 2020 and 2019 ~~and 2018~~ was primarily associated with expenses related to interest and amortization of debt issuance costs associated with our Credit Agreements, the change in fair value of warrants and interest income on cash held in a money market account.

For the three months ended ~~June 30,~~March 31, 2020 and 2019 ~~and 2018~~ there was no income tax expense.

~~The following table sets forth our results of operations for the six months ended June 30, 2019 and 2018:~~

Net sales increased $5.8 million, or 18.1%, to $38.1 million for the six months ended June 30, 2019 as compared to $32.2 million for the six months ended June 30, 2018. Net sales of our Breast Products segment was $20.9 million, an increase of $3.0 million for the six months ended June 30, 2019, as compared to $18.0 million for the six months ended June 30, 2018, driven primarily by an increase in the volume of sales of silicone gel breast implants and Allox2 and Dermaspan breast tissue expanders. Net sales of our miraDry segment was $17.1 million, an increase of $2.9 million, as compared to $14.3 million for the six months ended June 30, 2018 driven primarily by an increase in the volume of sales of miraDry consumable bioTips.

Cost of goods sold increased $1.5 million, or 12.0%, to $14.3 million for the six months ended June 30, 2019, as compared to $12.8 million for the six months ended June 30, 2018. The increase was primarily due to an increase in net sales.

The gross margins for the six months ended June 30, 2019 and 2018 were 62.5% and 60.4%, respectively. The increase is primarily due to increased sales of consumable bioTips in the miraDry reporting unit which carry higher margins.

Sales and marketing expenses increased $11.6 million, or 37.7%, to $42.3 million for the six months ended June 30, 2019, as compared to $30.7 million for the six months ended June 30, 2018. The increase was primarily due to higher employee-related costs as a result of increased sales headcount, and an increase in marketing expenses and initiatives.

R&D expenses increased $1.3 million, or 25.2%, to $6.3 million for the six months ended June 30, 2019, as compared to $5.1 million for the six months ended June 30, 2018. The increase was primarily due to an increase in costs related to clinical and regulatory activities.

G&A expenses increased $5.8 million, or 29.6%, to $25.3 million for the six months ended June 30, 2019, as compared to $19.5 million for the six months ended June 30, 2018. The increase is primarily related to an increase in consulting expenses, payroll, legal expenses and bad debt expense, offset by a decrease in contingent consideration fair value adjustments.

Goodwill and other intangible impairment expenses increased $12.7 million for the six months ended June 30, 2019 as compared to $0.0 for the six months ended June 30, 2018. The increase was due to impairments of goodwill and intangible assets in the miraDry reporting unit.

Other income (expense), net for the six months ended June 30, 2019 and 2018 was primarily associated with expenses related to interest and amortization of debt issuance costs associated with our Credit Agreements, the change in fair value of warrants and interest income on cash held in a money market account.

~~For the six months ended June 30, 2019 and 2018 there was no income tax expense.~~

Since our inception, we have incurred significant net operating losses and anticipate that our losses will continue in the near term. We expect our operating expenses will continue to grow as we expand our operations. We will need to generate significant net sales to achieve profitability. To date, we have funded our operations primarily with proceeds from the sales of preferred stock, borrowings under our term loans and convertible note, sales of our products since 2012, and the proceeds from the sale of our common stock in public offerings.

On ~~March 13,~~July 25, 2017, we entered into the SVB Loan Agreement. Under the terms of the SVB Loan Agreement, SVB made available to us a $15.0 million Revolving Line of Credit and a $5.0 million term loan. On July 25, 2017, we repaid in full our outstanding indebtedness under the SVB Loan Agreement and the agreement was terminated and replaced with theExisting Credit Agreements with ~~MidCap.~~

On July 25, 2017, we borrowed $25.0 million pursuant to the Term Loan Credit Agreement with MidCap and the other lenders party thereto. We used the proceeds (i) to repay in full our then-existing indebtedness under the SVB Loan Agreement, which totaled approximately $5.0 million, (ii) to pay fees and expenses in connection with the foregoing and (iii) for general corporate purposes. The Term Loan Credit Agreement provides for (i) the Closing Date Term Loan, (ii) until March 31, 2018, an additional $10.0 million term loan facility subject to the satisfaction of certain conditions, including FDA certification of the manufacturing facility operated by Vesta and (iii) an additional $5.0 million term loan facility subject to the satisfaction of certain conditions, including evidence that the Company’s Net Revenue (as defined in the Term Loan Credit Agreement) for the past 12 months was greater than or equal to $75.0 million. On April 18, 2018, we amended the Term Loan Credit Agreement with MidCap pursuant to which MidCap ~~agreed to adjust the date by which we must obtain FDA approval of our PMA supplement in order to access the March 2018 Term Loan until April 30, 2018.~~ Upon FDA approval in April 2018, the $10.0 million March 2018 Term Loan was funded. In addition, on July 25, 2017, we also entered into a Revolving Credit Agreement with MidCap and the other lenders party thereto. The amount available to be drawn under the Revolving Credit Agreement is based on a Borrowing Base equal to 85% of the net collectible value of eligible accounts receivable plus 40% of eligible finished goods inventory, provided that availability from eligible finished goods inventory does not exceed 20% of the Borrowing Base. We may make (subject to the applicable borrowing base at the time) and repay borrowings from time to time under the Revolving Credit Agreement until the maturity of the facility on December 1, 2021.

~~See Note 10 to the condensed consolidated financial statements for a full description of our long-term debt and revolving line of credit.~~

Midcap. On July 1, 2019, we entered into certain credit agreements with Midcap Financial Trust pursuant to which we repaid our existing indebtedness under our Existing Credit Agreements and the outstanding commitment fee was cancelled. On March 11, 2020, we issued the Convertible Note to Deerfield Partners, L.P. See Note 1511 – ~~Subsequent Events~~Debt to the condensed consolidated financial statements for ~~further discussion.~~a full description of our long-term debt, revolving line of credit, and convertible note.

In February 2018, we entered into an At-The-Market Equity Offering Sales Agreement with Stifel, Nicolaus & Company, Incorporated, or Stifel, as sales agent pursuant to which we may sell, from time to time, through Stifel shares of our common stock having an aggregate gross offering price of up to $50 million. As of ~~June 30, 2019~~March 31, 2020, ~~we have not~~the Company has sold ~~any~~37,000 shares of its common stock pursuant to the sales ~~agreement.~~ agreement, resulting in net proceeds after commissions of approximately $0.3 million.

On May 7, 2018, we completed an underwritten follow-on public offering in which we sold 7,407,408 shares of common stock at $13.50 per share, as well as 1,111,111 additional shares of common stock pursuant to the full exercise of the over-allotment option granted to the underwriters. Net proceeds to the Company were approximately $107.6 million after deducting underwriting discounts and commissions of $6.9 million and offering expenses of approximately $0.5 million.

Further, on June 7, 2019, we completed an underwritten follow-on public offering of 17,391,305 shares of common stock at $5.75 per share, as well as 2,608,695 additional shares of common stock pursuant to the full exercise of the over-allotment option granted to the underwriters. Net proceeds were approximately $107.7 million after deducting underwriting discounts and commissions of $6.9 million and offering expenses of approximately $0.4 million.

As of ~~June 30, 2019,~~March 31, 2020, we had ~~$146.1~~$112.1 million in cash and cash equivalents. Our historical cash outflows have primarily been associated with activities relating to commercialization and increases in working capital, including the expansion of our sales force and marketing programs. In addition, we have used cash to fund the acquisitions of miraDry, BIOCORNEUM and our tissue expander portfolio.

Due to the continued uncertainty relating to the COVID-19 pandemic, our revenues may continue to be adversely impacted. If we are unable to achieve certain revenue targets, we may breach certain financial covenants set forth in our Credit Agreement with MidCap Financial Trust. If we breach these covenants, MidCap will have the right to accelerate repayment of the outstanding amounts. In addition, a breach of a financial covenant in the Credit Agreement would result in a cross default under our Note with Deerfield, which would allow Deerfield to accelerate repayment of the amounts owed, subject to certain restrictions. In the event that any of MidCap or Deerfield accelerates the repayment of our indebtedness, there can be no assurance that we will have sufficient cash on hand to satisfy such obligations and our business operations may be materially harmed.

To fund our ongoing operating and capital needs, we may need to raise additional equity or debt capital. We believe we have sufficient capital resources to continue as a going concern through the next twelve months.

The following table shows a summary of our cash flows (used in) provided by operating, investing and financing activities for the periods indicated:

	Six Months Ended June 30,						Three Months Ended March 31,
	2019			2018			2020			2019
Net cash (used in) provided by:

Net change in cash, cash equivalents and restricted cash	$	59,189		$	86,031		$	24,454		$	(24,944	)

Net cash used in operating activities was ~~$48.6~~$27.2 million during the ~~six~~three months ended ~~June 30, 2019,~~March 31, 2020 as compared to ~~$31.2~~$24.6 million during the ~~six~~three months ended ~~June 30, 2018.~~March 31, 2019. The increase in cash used in operating activities between the ~~six~~three months ended ~~June 30,~~March 31, 2020 and 2019 ~~and 2018~~ was primarily associated with a higher net loss of ~~$64.1~~$28.6 million for the ~~six~~three months ended ~~June 30, 2019~~March 31, 2020 as compared to ~~$37.5~~$26.5 million for the ~~six~~three months ended ~~June 30, 2018,~~March 31, 2019, an increase in inventory, increases in prepaid expenses, other current assets, and other assets, decreases in accounts payable, accrueds, and ~~accrued~~other liabilities, ~~partially~~ offset by a ~~smaller~~ decrease in accounts receivable due to the timing of sales and ~~collections, an increase in stock based compensation expense, an increase in goodwill and other intangible impairment, and an increase in customer deposits.~~collections.

Net cash used in investing activities was ~~$2.1~~$1.2 million during the ~~six~~three months ended ~~June 30, 2019~~March 31, 2020 as compared to ~~$0.2~~$0.6 million during the ~~six~~three months ended ~~June 30, 2018.~~March 31, 2019. The increase in cash used in investing activities between the ~~six~~three months ended ~~June 30,~~March 31, 2020 and 2019 ~~and 2018~~ was due to an increase in property and equipment purchases.

Net cash provided by financing activities was ~~$109.9~~$52.8 million during the ~~six~~three months ended ~~June 30, 2019~~March 31, 2020 as compared to ~~$117.3~~$0.3 million during the ~~six~~three months ended ~~June 30, 2018.~~March 31, 2019.

Our liquidity position and capital requirements are subject to a number of factors. For example, our cash inflow and outflow may be impacted by the following:

Our primary short-term capital needs, which are subject to change, include expenditures related to:

Although we believe the foregoing items reflect our most likely uses of cash in the short-term, we cannot predict with certainty all of our particular short-term cash uses or the timing or amount of cash used. If cash generated from operations is insufficient to satisfy our working capital and capital expenditure requirements, we may be required to sell additional equity or debt securities or obtain credit facilities. Additional capital, if needed, may not be available on satisfactory terms, if at all. Furthermore, any additional equity financing may be dilutive to stockholders, and debt financing, if available, may include restrictive covenants. For a discussion of other factors that may impact our future liquidity and capital funding requirements, see “Risk Factors — Risks Related to Our Financial Results” in our Annual Report on Form 10-K.

During the periods presented we did not have, nor do we currently have, any off-balance sheet arrangements as defined under SEC rules.

As of ~~June 30, 2019,~~March 31, 2020, we had ~~$146.1~~$112.1 million in cash and cash equivalents. We generally hold our cash in checking accounts and interest-bearing money market accounts. Our exposure to market risk related to interest rate sensitivity is affected by changes in the general level of U.S. interest rates. Due to the short-term maturities of our cash equivalents and the low risk profile of our investments, an immediate 100 basis point change in interest rates would not have a material effect on the fair market value of our cash equivalents. We have established guidelines regarding approved investments and maturities of investments, which are designed to maintain safety and liquidity.

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with U.S. GAAP. We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our periodic and current reports that we file with the SEC 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 ~~chief executive officer~~Chief Executive Officer, or CEO, and ~~chief financial officer,~~Chief Financial Officer, or CFO, as appropriate, to allow timely decisions regarding required disclosure. Our independent registered public accounting firm will be required to attest to the effectiveness of our internal control over financial reporting for our Annual Report on Form 10-K for the first year we are no longer an “emerging growth company” under the JOBS Act.

As of ~~June 30, 2019~~March 31, 2020, we carried out an evaluation, under the supervision and with the participation of our management, including our ~~Chief Executive Officer, or~~ CEO and ~~Chief Financial Officer, or~~ CFO, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on that evaluation, the CEO and CFO concluded that the Company’s disclosure controls and procedures were not effective as of March 31, 2020 as a result of the material weakness described in our Annual Report on Form 10-K and below.

The control environment was ineffective in holding individuals accountable for the operation of their internal control responsibilities. This control failure prevented the effective operation of controls over goodwill and intangible asset impairment, including the underlying financial data, calculations and assumptions supporting the forecasted financial information utilized to measure the fair value of the reporting unit, intangible assets, and the associated

impairment charges. This deficiency did not result in an adjustment but still represented a material weakness in our internal control over financial reporting as of December 31, 2019 because there is a reasonable possibility that material misstatements to our consolidated financial statements would not be prevented or detected on a timely basis.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such ~~date.~~that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

As disclosed in our Annual Report, we have identified and begun to implement several actions designed to remediate the material weakness. Our remediation process includes, but is not limited to communicating expectations over performance of controls, monitoring for compliance with those expectations, and holding individuals accountable for their roles related to internal control over financial reporting.

~~There was~~Except as discussed above, there have been no ~~change~~changes in our internal control over financial reporting that occurred during the period covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

From time to time, we are involved in legal proceedings and regulatory proceedings arising out of our operations. We establish reserves for specific liabilities in connection with legal actions that we deem to be probable and estimable. The ability to predict the ultimate outcome of such matters involves judgments, estimates, and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates. Information regarding certain legal proceedings is provided in this Quarterly Report in Note 1415 of the ~~Condensed Consolidated Financial Statements.~~condensed consolidated financial statements.

Except as set forth below, there have been no material changes from the risk factors disclosed in Part I, Item 1A, of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, ~~2018,~~2019, which are incorporated herein by reference.

~~Failure~~The COVID-19 pandemic has adversely affected, and continues to adversely affect, our business, our operations and our financial results. Future pandemics, epidemics or outbreaks of an infectious disease may similarly affect our business, our operations and our financial results.

The recent outbreak of COVID-19 originated in Wuhan, China, in December 2019 and has since spread to multiple countries, including the United States. On March 11, 2020, the World Health Organization declared COVID-19 a pandemic. The COVID-19 pandemic has drastically impacted healthcare systems in the United States and globally and resulted in travel restrictions which impact medical tourism and our sales professionals’ ability to travel. In addition, hospitals have limited access for non-patients, including our sales professionals, which could negatively impact our access to physicians. As an aesthetics company, a significant percentage of our products are utilized in elective surgeries or procedures, which may be deferred or avoided altogether due to the COVID-19 outbreak, materially impacting our financial results. Future pandemics or other outbreaks of infectious disease may result in a similar period of business disruption, including reduced sales as patients might cancel or defer elective procedures or otherwise avoid medical facilities, resulting in reduced patient volumes and operating revenues. Governmental agencies and hospital administrators may also instruct hospitals to postpone some elective procedures in preparation for COVID-19-related hospitalizations. The continued spread of COVID-19, or another infectious disease, could

also result in delays or disruptions in our supply chain or adversely affect our manufacturing facilities and personnel. The COVID-19 outbreak has materially impacted our operations and financial results and continues to be fluid and uncertain, making it difficult to forecast the final impact it could have on our future operations or financial results.

Our debt obligations could impair our financial condition and limit our operating flexibility.

Our indebtedness under our credit agreements with MidCap Financial Trust, or the Credit Agreements, our Convertible Note with Deerfield and our other financial obligations could:

Our financial covenants in the ~~suspension or withdrawal~~Credit Agreements require us to achieve certain levels of ~~our PMA.~~

~~We received pre-market approval, or PMA, for our silicone gel breast implants from the FDA in 2012. As~~net revenue calculated on a condition of PMA approval, the FDA imposes certain requirements in order to maintain the PMA. Failure to comply with the applicable regulatory requirements can result in, among other things, warning letters, administrative or judicially imposed sanctions such as injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, the suspension or withdrawal of our PMA, or criminal prosecution. For example, in March 2019, we received a warning letter from the FDA stating that we failed to meet the expected patient follow-up rate in one of our post-approval studies for our silicone gel breast implants. The warning letter stated that failure to promptly correct this deficiency may result in the withdrawal of our PMA. We provided a comprehensive responserolling monthly basis. Due to the ~~FDA and are working collaboratively with~~continued uncertainty relating to the ~~agency~~COVID-19 pandemic, our revenues may continue to ~~quickly and fully resolve this matter.~~be adversely impacted. If we are unable to ~~timely correct~~achieve certain revenue targets, we may breach certain financial covenants set forth in our Credit Agreements. If we breach these covenants, MidCap will have the ~~deficiency included~~right to accelerate repayment of the outstanding amounts. In addition, a breach of a financial covenant in the ~~warning letter~~Credit Agreement would result in a cross default under our Convertible Note with Deerfield, which would allow Deerfield to ~~the satisfaction~~accelerate repayment of the ~~FDA,~~amounts owed, subject to certain restrictions. In the event that any of MidCap or Deerfield accelerates the repayment of our indebtedness, there can be no assurance that we will have sufficient cash on hand to satisfy such obligations and our business operations may be materially harmed.

Furthermore, there is no guarantee that we will be able to pay the principal and interest under the Credit Agreements or the Convertible Note or that future working capital, borrowings or equity financing will be available to repay or refinance any amounts outstanding under the Credit Agreements or Convertible Note. Our obligations under the Credit Agreements are secured by a perfected security interest in all of our tangible and intangible assets (including our intellectual property assets), except for certain customary excluded property and all of our and our subsidiaries capital stock, with certain limited exceptions. In addition, we may enter into debt agreements in the future that may contain similar or more burdensome terms and covenants, including financial covenants.

We may not successfully integrate newly acquired businesses into our business operations or realize the benefits of partnerships with other companies, acquisitions of complementary products or technologies or other strategic alternatives.

We have completed a series of business and product acquisitions including our acquisition of our manufacturing operations from Vesta, our acquisition of miraDry, our product acquisitions, including BIOCORNEUM and our tissue expanders portfolio. As a result of these acquisitions, we have undergone substantial changes to our business and product offerings in a short period of time. In addition, in the future, we may consider other opportunities to partner with or acquire other businesses, products or technologies that may enhance our product platform or technology, expand the breadth of our markets or customer base or advance our business strategies.

Integrating the business practice and operations of a new business with that of our own is a complex, costly and time-consuming process, which requires significant management attention and resources. The integration process may disrupt our existing operations and, if implemented ineffectively, would preclude realization of the full benefits expected by us. Our failure to meet the challenges involved in successfully integrating our acquisitions in order to realize the anticipated benefits may cause an interruption of, or a loss of momentum in, our operating activities and could adversely affect our results of operations. For example, we recently determined to refocus our miraDry reporting unit to driving sales of consumable bioTips to our existing installed base. There can be no assurances that we will achieve significant sales of the miraDry system under this refocused plan or, if we ~~fail~~do, that we will be able to ~~meet~~do so in a profitable manner. Potential difficulties, costs and delays we may encounter as part of the integration process may include:

Any one or all of these factors may increase operating costs or lower anticipated financial performance. Many of these factors are also outside of our control. In addition, even if new business operations are integrated successfully, we may not realize the full benefits of the acquisition, including the synergies, cost savings or sales or growth opportunities that we expect or within the anticipated time frame. Additional unanticipated costs may be incurred in the integration of the businesses. All of these factors could decrease or delay the expected accretive effect of the transaction, and negatively impact the price of our common stock. The failure to integrate the business operations of miraDry or any acquired business successfully would have a material adverse effect on our business, financial condition and results of operations. As noted above, we determined to refocus efforts on driving sales of bioTips to our existing installed base. There can be no assurance that this shift in focus will allow us to realize the expected benefits from this acquisition.

If we are unable to drive sales of our bioTips to our existing installed base of miraDry systems, our business and future prospects will be harmed.

In April 2020, we determined to focus on driving high margin, bioTip utilization to our existing installed base combined with a controlled placement of consoles. We expect that the net sales we generate from our bioTips will represent high margin sales (on a gross margin basis) and account for a substantial amount of our net sales for the next several years, with high margin consumables comprising a sizable percentage of our miraDry segment’s net sales. Accordingly, our success depends on the acceptance among physicians and patients of the miraDry procedure as a preferred treatment for being sweat-bothered. Although we have received FDA clearance to market the miraDry procedure for the treatment of primary axillary hyperhidrosis, odor and permanent hair reduction in the United States and are approved or are otherwise free to market the miraDry procedure for the treatment of primary ancillary hyperhidrosis in adults in over 40 international markets, the degree of market acceptance of the miraDry procedure by physicians and patients is unproven. We believe that market acceptance of the miraDry procedure will depend on many factors, including:

In addition, the COVID-19 pandemic has limited our ability to educate physicians and drive market acceptance of the procedure. We cannot guarantee that the miraDry procedure will achieve broad market acceptance among physicians and patients. We expect to derive a substantial portion of sales from the sale of our consumable bioTip products, which represent higher margin products within our product portfolio. As a result, any failure of this product to achieve meaningful market acceptance will harm our business, sales, profitability and future prospects.

If changes in the economy and consumer spending reduce consumer demand for our products, our sales and profitability would suffer.

We are subject to the risks arising from adverse changes in general economic and market conditions, pandemics or political actions including new or increased trade protection policies such as tariffs, particularly in China, where certain components of our miraDry products are manufactured. Certain elective procedures, such as breast augmentation and the miraDry procedure, are typically not covered by insurance. Adverse changes in the economy or a “trade war” may cause consumers to reassess their spending choices and reduce the demand for these surgeries and other procedures and could have an adverse effect on consumer spending. This shift could have an adverse effect on our net sales and profitability. Furthermore, consumer preferences and trends may shift due to a variety of

factors, including changes in demographic and social trends, public health initiatives and product innovations, which may reduce consumer demand for our products. For example, in December 2019, there was an outbreak of a novel strain of coronavirus (COVID-19) in Wuhan, China that has since spread to other regions in China and the rest of the world. To contain the outbreak, the Chinese central government extended the Lunar New Year holiday for one week and issued guidance pursuant to which local governments in China have taken temporary measures to limit large gatherings and impose travel restrictions. As a result, our bioTip manufacturer in China was required to close for a week and has only recently reopened and is operating at reduced capacity as of the date of this Quarterly Report on Form 10-Q. In addition, as the outbreak spread through the United States and globally, we have experienced a significant reduction in demand as non-emergency medical procedures are deferred. There can be no assurances that once healthcare systems resume normal activity that these deferred procedures will be rescheduled. The outbreak has adversely affected our financial condition and results of operations and will likely continue to adversely impact our operations until heathcare systems resume normal activity. At this point, the duration and extent of such impact is uncertain.

If we are unsuccessful in executing our cost plan, our business and results of operations may be adversely affected.

In November 2019, we announced an organizational efficiency initiative (the “Plan”) designed to reduce spending and simplify operations to better align our cost structure to our long-term margin targets. Under the Plan, we will implement numerous initiatives to reduce spending, including closing the Santa Clara offices of miraDry, Inc. (“miraDry”), and consolidating a number of business support services via a shared services organization at our Santa Barbara headquarters. Under the Plan, we also intend to reduce our workforce in a series of targeted reductions, which we expect to be completed by the end of 2020. We cannot provide assurance that our Plan will be successful, that anticipated cost savings will be realized, that our operations, business and financial results will improve and/or that these efforts will not disrupt our operations (beyond what is intended).

In April 2020, we implemented additional workforce reductions as cost savings measures. Our ability to achieve the anticipated cost savings and other benefits within the expected time frames is subject to many estimates and assumptions, which are subject to significant economic, competitive and other uncertainties, some of which are beyond our control. Further, we may experience delays in the timing of these efforts and/or higher than expected or unanticipated costs in implementing them. Moreover, changes in the size, alignment or organization of our workforce could adversely affect employee morale and retention, relations with customers and business partners, our ability to develop and deliver products and services as anticipated and/or impair our ability to realize our current or future business and financial objectives. If we do not succeed in these efforts, if these efforts are more costly or time-consuming than expected, if our estimates and assumptions are not correct, if we experience delays or if other unforeseen events occur, our business and results of operations may be adversely affected.

Any disruption at our facilities could adversely affect our business and operating results.

Our principal offices are located in Santa Barbara, California. Substantially all of our operations are conducted at this location, including customer service, development and management and administrative functions. Substantially all of our inventory of Breast Products is held at a second location in Santa Barbara, California, and, with the Vesta Acquisition, we manufacture our breast implants at a third location in Wisconsin. Despite our efforts to safeguard our facilities, including acquiring insurance, adopting health and safety protocols and utilizing off-site storage of computer data, vandalism, terrorism, public health crisis (such as the recent COVID-19 outbreak) or a natural or other disaster, such as an earthquake, tornado, fire or flood, could damage or destroy our inventory of finished goods, cause substantial delays in our operations, result in the loss of key information and cause us to incur additional expenses. Our insurance may not cover our losses in any particular case. In addition, regardless of the level of insurance coverage, damage to our facilities may have a material adverse effect on our business, financial condition and operating results.

We accepted a loan under the CARES Act pursuant to the Paycheck Protection Program, or the PPP, which loan may not be forgiven or may subject us to challenges and investigations regarding qualification for the loan. In addition, we may be subject to audit in connection with the loan and should we request that the loan be forgiven, the United States Small Business Administration, or SBA, will conduct a full audit in connection with the loan. If there is any adverse finding from the audit or if we are subject to any other investigation or challenge in connection with the loan, we could be required to return the full amount of the PPP loan plus interest, which could reduce our liquidity, and could be subject to significant fines, damages and penalties and its business could otherwise be adversely affected, whether or not there is an adverse finding. Such events could have a material adverse effect on our business, financial condition and results of operations.

In April 2020, we were granted a loan of $6.7 million under the PPP of the CARES Act, or the PPP Loan, all or a portion of which may be forgiven dependent on our use of proceeds. The PPP Loan matures on April 27, 2022 and bears interest at a rate of 1.0% per annum. All or a portion of the PPP Loan may be forgiven by the SBA upon application by us beginning 60 days, but not later than 120 days, after loan approval and upon documentation of expenditures in accordance with the SBA’s requirements. Under the CARES Act, loan forgiveness is available for the sum of documented payroll costs, covered rent payments, covered mortgage interest and covered utilities during the eight week period beginning on the date of loan approval. Not more than 25% of the forgiven amount may be for non-payroll costs. The amount of the PPP Loan eligible to be forgiven will be reduced if our full-time headcount declines, or if salaries and wages for employees with salaries of $100,000 or less annually are reduced by more than 25%. We will be required to repay any portion of the outstanding principal that is not forgiven, along with accrued interest, in accordance with the amortization schedule described above, and we cannot provide any assurance that we will be eligible for loan forgiveness, that we will ultimately apply for forgiveness, or that any amount of the PPP Loan will ultimately be forgiven by the SBA. Furthermore, on April 28, 2020, the Secretary of the U.S. Department of the Treasury stated that the SBA will perform a full review of any PPP loan over $2.0 million before forgiving the loan.

The PPP Loan application required us to certify, among other things, that the current economic uncertainty made the PPP Loan request necessary to support our ongoing operations. While we made this certification in good faith after analyzing, among other things, our financial situation and access to alternative forms of capital, and believe that we satisfied all eligibility criteria for the PPP Loan and that our receipt of the PPP Loan is consistent with the broad objectives of the PPP of the CARES Act, the certification described above does not contain any objective criteria and is subject to interpretation. In addition, the SBA has stated that it is unlikely that a public company with substantial market value and access to capital markets will be able to make the required certification in good faith. The lack of clarity regarding loan eligibility under the Paycheck Protection Program has resulted in significant media coverage and controversy with respect to public companies applying for and receiving loans. If, despite our good faith belief that we satisfied all eligibility requirements for the PPP Loan, we are found to have been ineligible to receive the PPP Loan or in violation of any of the ~~other requirements of our PMA, our PMA~~laws or governmental regulations that apply to us in connection with the PPP Loan, including the False Claims Act, we may be ~~suspended~~subject to penalties, including significant civil, criminal and administrative penalties and could be required to repay the PPP Loan. In the event that we seek forgiveness of all or ~~withdrawn~~a portion of the PPP Loan, we will also be required to make certain certifications which will be subject to audit and review by governmental entities and could subject us to significant penalties and liabilities if found to be inaccurate, including under the False Claims Act. In addition, our receipt of the PPP Loan may result in adverse publicity and damage to our reputation, and a review or audit by the ~~FDA.~~SBA or other government entity or claims under the False Claims Act could consume significant financial and management resources. Any ~~such suspension or withdrawal would have a significant negative impact on~~of these events could harm our business, results of operations orand financial condition.

~~None.~~On May 11, 2020, the Company entered in to the Second Amendment to Amended and Restated Credit and Security Agreement (Term Loan) (the “Term Agreement”), by and among the Company, certain of the Company’s subsidiaries, the lenders party thereto and MidCap Financial Trust as agent (the “Term Amendment”). The Term Amendment provides for, among other things, the prepayment by the Company of approximately $25.0 million of outstanding principal plus accrued interest, with the parties agreeing to waive the prepayment fee with respect to this amount. In connection with the prepayment, the Term Amendment requires the Company to prepay $1.25 million of the exit fee under the Term Agreement. The Term Amendment increases the tranche 3 commitment amount from $10.0 million to $15.0 million, extends the tranche 3 termination date from December 31, 2020 to June 30, 2021, and amends certain conditions upon which the tranche 3 commitment can be withdrawn, including evidence that the Company’s Net Revenue for the past six months was greater than or equal to $30.0 million. In addition, the Term Amendment amends certain financial requirements including reducing the Company’s minimum unrestricted cash amount from $20.0 million to $5.0 million and amends certain minimum net revenue requirements. Further, the monthly minimum net revenue requirements were revised to be calculated on a trailing three month basis. On May 11, 2020, the Company prepaid $25.0 million of principal, $1.25 million of the exit fee, and $0.1 million of accrued interest.

In addition, on May 11, 2020, the Company entered in to the Second Amendment to Amended and Restated Credit and Security Agreement (Revolving Loan), by and among the Company, certain of the Company’s subsidiaries, the lenders party thereto and MidCap Financial Trust as agent (the “Revolving Amendment”). The Revolving Amendment includes conforming changes to reflect the changes in the Term Amendment. In addition, the Revolving Amendment reduces the borrowing base by the portion of the eligible inventory previously included in the calculation.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
