Summary of Significant Accounting Policies
a.
Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Sientra, Inc. (“Sientra”, the “Company”, “we”, “our”, or “us”) in this Quarterly Report on Form 10-Q have been prepared in accordance with U.S. generally accepted accounting principles, or "GAAP", and the rules and regulations of the U.S. Securities and Exchange Commission, or the "SEC". Accordingly, they do not include certain notes and financial presentations normally required under GAAP 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, 2022 filed with the SEC on April 18, 2023, or the Annual Report. The results for the three months ended March 31, 2023 are not necessarily indicative of results to be expected for the year ending December 31, 2023, any other interim periods, or any future year or period.

 

Reverse Stock Split

 

On January 19, 2023, the Company effected a 1-for-10 reverse stock split (the “Reverse Stock Split”) of the Company’s issued and outstanding common stock, par value $0.01 per share (the “Common Stock”). by the filing of a Certificate of Amendment (the “Certificate”) with the Secretary of State of the State of Delaware pursuant to the Delaware General Corporation Law. The Reverse Stock Split became effective on January 19, 2023.

 

As a result of the Reverse Stock Split, every 10 shares of Common Stock issued and outstanding were automatically reclassified into one new share of common stock. The Reverse Stock Split did not modify any rights or preferences of the shares of Common Stock. Proportionate adjustments will be made to the exercise or conversion prices and the number of shares underlying the Company’s outstanding equity awards, convertible securities and warrants, as well as to the number of shares issued and issuable under the Company’s equity incentive plans. The Common Stock issued pursuant to the Reverse Stock Split will remain fully paid and non-assessable. The Reverse Stock Split will not affect the number of authorized shares of Common Stock or the par value of the Common Stock. All share information in the accompanying financial statements has been adjusted to reflect the results of the Reverse Stock Split.

 

Discontinued Operations of miraDry

As a result of the miraDry sale discussed in Note 2, the miraDry business met the criteria to be reported as discontinued operations. Therefore, the Company is reporting the historical results of miraDry, including the results of operations, cash flows, and related assets and liabilities, as discontinued operations for all periods presented herein through the date of the Sale. Unless otherwise noted, the accompanying notes to the unaudited condensed consolidated financial statements have all been revised to reflect continuing operations only. Following the sale the Company has one operating segment in continuing operations named Plastic Surgery, formerly known as Breast Products.

 

b.
Liquidity and Going Concern

 

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared assuming the Company will continue as a going concern and in accordance with generally accepted accounting principles in the United States of America. The going concern basis of presentation assumes that the Company will continue in operation one year after the date these financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business.

Pursuant to the requirements of the Financial Accounting Standards Board’s Accounting Standards Codification (“ASC”) Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these condensed consolidated financial statements are issued. This evaluation does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within control of the Company as of the date the condensed consolidated financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued.

Since the Company’s inception, it has incurred recurring losses and cash outflows from operations and the Company anticipates that losses will continue in the near term. During the three months ended March 31, 2023, the Company incurred net losses of $12.9 million and used $6.7 million of cash from continuing operations. As of March 31, 2023, the Company had cash and cash equivalents of $19.4 million. As a result of these conditions substantial doubt exists about our ability to continue as a going concern for a period of at least one year from the date of issuance of these unaudited condensed consolidated financial statements. The unaudited condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

 

In an effort to alleviate these conditions, management is currently evaluating various cost-saving measures in order to reduce operating expenses and cash outflows. However, the Company will need to generate a significant increase in net sales to further improve profitability and cash inflows, which is dependent upon continued growth in our Plastic Surgery segment and the launch of new products and partnerships. Additionally, we are evaluating various funding alternatives to improve liquidity and may seek to raise additional equity or debt capital, refinance our debt obligations or obtain waivers, and/or scale back or freeze our organic growth plans to manage our liquidity and capital resources. As the Company seeks additional sources of financing, there can be no assurance that such financing would be available to the Company on favorable terms or at all. The Company’s ability to obtain additional financing in the equity capital markets is subject to several factors, including market and economic conditions, the Company’s performance and investor sentiment with respect to the Company and its industry.

 

During 2022, to fund ongoing operating and capital needs, the Company raised additional capital through the sale of equity securities and incremental debt financing. See Note 7 to the condensed consolidated financial statements for further details.

Recent Accounting Pronouncements

 

Recently Adopted Accounting Standards

 

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. The amendment eliminates certain accounting models and simplifies the accounting for convertible instruments and enhances disclosures for convertible instruments and earnings per share. The amendments are effective for public entities excluding smaller reporting companies for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023 including interim periods within those fiscal years and early adoption is permitted. The Company adopted this guidance effective January 1, 2023 under the modified retrospective adoption approach and there was no material impact on its 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 the ASU 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.

 

d.
Risks and Uncertainties

 

The COVID-19 pandemic and its related macroeconomic effects significantly impacted our business and results of operations in past years. At the height of the pandemic and as an aesthetics company, the surgical procedures involving our breast products were susceptible to local and national government restrictions. The inability or limited ability to perform non-emergency procedures significantly harmed our revenues since the second quarter of 2020 and during the first quarter of 2022.

In addition, the global economy, including the financial and credit markets, has recently experienced extreme volatility and disruptions, including increases to inflation rates, rising interest rates, declines in consumer confidence, declines in economic growth, and uncertainty about economic stability. The severity and duration of the impact of these conditions on our business cannot be predicted.

The estimates used for, but not limited to, determining the collectability of accounts receivable, fair value of long-lived assets and goodwill, and sales returns liability required could be impacted by the factors described above. While the full impact and duration of the factors noted above 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.

Discontinued Operations

 

On June 10, 2021, the Company completed the sale of its miraDry business (the “Sale”) to miraDry Acquisition Company, Inc., a Delaware corporation (“Buyer”), an entity affiliated with 1315 Capital II, LP, as a result of the Company’s strategic decision to focus investment on its core Plastic Surgery segment. The Sale was made pursuant to the terms and conditions of the Asset Purchase Agreement (the “Purchase Agreement”), dated May 11, 2021, among the Company and certain of its subsidiaries, Buyer, and, solely for purposes of Section 8.14 of the Purchase Agreement, 1315 Capital II, LP. The aggregate purchase price was $10.0 million, which after certain adjustments for agreed upon changes in the estimated net asset value amount of purchased assets and assumed liabilities resulted in net cash proceeds of $11.3 million to the Company on the date of close. In October 2021, the Company finalized the transaction and paid $3.2 million to the Buyer in accordance with the agreed upon post close changes in the net asset value and recognized a loss on sale of $2.5 million.

In accordance with the Purchase Agreement, assumed liabilities did not include product liabilities, environmental, and employee claims arising prior to the closing date. The Purchase Agreement also included customary representations and warranties, as well as certain covenants, including, among other things, that: (i) the Company will abide by certain non-solicitation, exclusivity, and non-competition covenants, and (ii) the Company would enter into a transition services agreement (“TSA”) to provide certain transition services related to the business.

 

Under the TSA, the Company provided certain post-closing services to the Buyer related to the miraDry business for a period of six months, including accounting, accounts receivable support, customer service, IT, regulatory, quality assurance, and clinical support. As consideration for these services, the Buyer reimbursed the Company for direct and certain indirect costs, as well as certain overhead or administrative expenses related to operating the business. The Company recognized $0.2 million of TSA fees and cost reimbursements in operating expenses from continuing operations in the condensed consolidated statement of operations for the three months ended March 31, 2022. Since

the closing date, the Company has received $0.3 million relating to the TSA services and has recorded a receivable of $0.1 million within other current assets in the condensed consolidated balance sheets. In connection with the accounts receivable support under the TSA, since the closing date the Company received $2.3 million in customer payments and has remitted $2.3 million to the Buyer. As of March 31, 2023, the Company does not have a payable to the Buyer on the condensed consolidated balance sheets.

 

Additionally, the Company and the Buyer entered into a sublease agreement whereby the Buyer subleased the miraDry office space in Santa Clara, CA. The sublease term was for an initial period of six months, with subsequent option periods for up to a total of twenty-four months. Following the initial period, the Buyer exercised an additional period of six months, and an extension of twelve months thereafter. The sublease expired in March 2023. During the three months ended March 31, 2023, the Company recognized $0.3 million of sublease income in general and administrative expenses in the consolidated statements of operations.

The Sale met the discontinued operations criteria given that the business is a component and represented a strategic shift. The following table presents the aggregate carrying amounts of major classes of assets and liabilities of discontinued operations (in thousands):

Revenue from Contract with Customer [Abstract]

Revenue

The Company generates revenue primarily through the sale and delivery of promised goods or services to customers. Sales prices are documented in the executed sales contract, purchase order or order acknowledgement prior to the transfer of control to the customer. Typical payment terms are 30 days.

Revenue contracts may include multiple products or services, each of which is considered a separate performance obligation. Performance obligations typically include the delivery of promised products, such as breast implants, tissue

expanders, BIOCORNEUM, Viality, and SimpliDerm, along with service-type warranties. Other deliverables are sometimes promised but are ancillary and insignificant in the context of the contract as a whole. Revenue is allocated to each performance obligation based on its relative standalone selling price. The Company determines standalone selling prices based on observable prices for all performance obligations with the exception of the service-type warranty under the Platinum20 Limited Warranty Program, or "Platinum20".

The Company introduced Platinum20 in May 2018 on all breast implants implanted in the United States or Puerto Rico on or after May 1, 2018. Additionally, Platinum20 Program applies to all breast implants that are implanted in Canada on or after March 23, 2022. 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. The Company considers the service warranty component as an additional performance obligation and defers revenue at the time of sale 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 March 31, 2023 were as follows (in thousands):

The liability for the short-term portion is included in “Accrued and other current liabilities” and the long-term portion is included in “Other liabilities” in the condensed consolidated balance sheets.

 

Revenue for service warranties are recognized ratably over the term of the agreements. Specifically for Platinum20, the performance obligation is satisfied at the time that the benefits are provided and are expected to be satisfied over the following 3 to 24 month period for financial assistance and 20 years for product replacement.

 

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. A portion of the Company’s revenue is generated from the sale of consigned inventory 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 used, not when the consigned products are delivered to the customer’s location.

 

Sales Return Liability

 

With the exception of the Company’s BIOCORNEUM scar management products, Viality, inventory held on consignment, and products sold to international customers, the Company allows for the return of products from customers within six months after the original sale, which is accounted for as variable consideration. A sales return liability is established based on estimated returns using relevant historical experience taking into consideration recent gross sales and notifications of pending returns, as adjusted for changes in recent industry events and trends. Estimated future sales returns for the current and prior periods are recorded as a reduction of revenue and as a sales return liability in the current period. Actual sales returns for current and prior periods, 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 and noted separately as a change in estimate. The following table provides a rollforward of the sales return liability (in thousands):

Fair Value of Financial Instruments

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 contingent consideration and the convertible feature related to the convertible note are discussed in Note 5. As discussed in Note 5, the fair value of the convertible notes conversion features has been reclassified to equity as of March 31, 2023 and the conversion features no longer requires measurement at fair value. The convertible notes are carried at amortized cost on the condensed consolidated balance sheet.

The fair value of the long-term debt is based on the amount of future cash flows associated with the instrument discounted using the Company’s market rate. As of March 31, 2023 and December 31, 2022, the carrying value and fair value of the convertible note were as follows (in thousands):

f.
Liabilities measured at 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:

•
Level 1 — Quoted prices in active markets for identical assets or liabilities.
•
Level 2 — Observable inputs (other than Level 1 quoted prices) such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.
•
Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.

Contingent consideration

The contingent consideration balance consists of milestone payments related to the acquisition of Viality and future royalty payments related to the acquisition of BIOCORNEUM.

The Company assessed the fair value of all contingent consideration using a Monte-Carlo simulation model. The contingent consideration related to Viality is based on the achievement of certain clinical endpoints following the completion of a study measuring retention rates using the fat transfer products. The significant assumptions utilized in the fair value measurement was risk-free rate, the probable retention rate based on historical data and the Company's equity volatility of 121%. Any subsequent changes to the fair value of contingent consideration will be recorded as an adjustment to the carrying value of the assets acquired.

The contingent consideration related to the acquisition of BIOCORNEUM consists of royalty obligations based on future net sales for a defined term, beginning in 2024. The significant assumption utilized in the fair value measurement was the discount rate, which was 19.0%.

As these inputs are not observable, the overall fair value measurement of the contingent consideration is classified as Level 3.

 

 

Derivative liability

The Company identified certain embedded derivatives related to the conversion features of the Convertible Notes. Refer to Note 7 to the unaudited condensed consolidated financial statements for further details on the Convertible Notes. In accordance with ASC 815-40, Derivatives and Hedging Activities, the embedded conversion options contained within the Convertible Notes were accounted for as derivative liabilities at the date of issuance and shall be adjusted to fair value through each reporting date. The Company utilized a binomial lattice model to calculate the fair value of the embedded derivatives. Significant observable and unobservable inputs include, conversion price, stock price, dividend rate, expected volatility, risk-free rate, and the probability of conversion to common shares at the Base Conversion Rate in the event of a major transaction (e.g., a change in control). The binomial lattice model is a Level 3 valuation technique because it requires the development of significant internal assumptions in addition to observable market indicators.

 

On January 19, 2023, the Company effected a Reverse Stock Split, and upon the effectiveness of the Reverse Stock Split, the Company deemed it appropriate to reassess the conversion features of its Convertible Notes. As noted above, the conversion features were separately bifurcated and accounted for as embedded derivatives. Based on the Company’s reassessment, it has concluded that the conversion features meet the criteria for equity classification and has reclassified the fair value of the bifurcated conversion features to “Additional paid in capital” on the condensed consolidated balance sheet.

 

The following tables present information about the Company’s liabilities that are measured at fair value on a recurring basis as of March 31, 2023 and December 31, 2022 and indicate the level of the fair value hierarchy utilized to determine such fair value (in thousands):

Convertible and 2022 Note

 

On October 12, 2022, the Company, entered into the “Restated Agreement” that amends and restates the Existing Agreement with Deerfield. In connection with the Restated Agreement, the Company and Deerfield entered into an Exchange Agreement pursuant to which Deerfield exchanged $10.0 million of principal under the Original Note for securities of the Company, reducing the outstanding principal amount of the original convertible note to $50.0 million. Additionally, on the date of the Restated Agreement and pursuant to the terms thereof, the Company issued and sold an additional senior secured convertible note in a principal amount of $23.0 million (the “2022 Note” and, together with the Original Note, the “Convertible Notes”).

 

Pursuant to the Convertible Notes, Deerfield has the option to demand repayment of all outstanding principal, and any unpaid interest accrued thereon and any other amounts payable under the Restated Agreement (including the Exit Fee (in the case of the 2022 Note) and any make whole amounts), in connection with a Major Transaction (as defined in the Convertible Notes), which shall include, among others, any acquisition or other change of control of the Company; the sale or transfer of assets of the Company equal to more than 50% of the Enterprise Value (as defined in the Convertible Notes) of the Company; a liquidation, bankruptcy or other dissolution of the Company; or if at any time shares of the Company’s common stock are not listed on an Eligible Market (as defined in the Convertible Notes). The Convertible Notes are subject to specified events of default, the occurrence of which would entitle Deerfield to immediately demand repayment of all outstanding principal and accrued interest on the Convertible Note. Such events of default include, among others, failure to make any payment under the Convertible Note when due, failure to observe or perform any covenant under the Restated Agreement or the other transaction documents related thereto (subject to a standard cure period), the failure of the Company to be able to pay debts as they come due, the commencement of bankruptcy or insolvency proceedings against the Company, a material judgment levied against the Company and a material default by the Company under the Convertible Note.

On the payment, repayment, dischargement, redemption or prepayment of the 2022 Note or upon a Successor Major Transaction Conversion (as defined in the 2022 Note), the Company will pay a non-refundable exit fee equal to 1.95% of the 2022 Note so paid, repaid, discharged, redeemed or prepaid, as the case may be.

The Company used the proceeds from the new 2022 Note to repay in full the outstanding amounts under its Second Amended and Restated Credit and Security Agreement (Term Loan), dated December 31, 2021, by and among the Company, certain of its wholly owned subsidiaries, the lenders party thereto and MidCap Financial Trust, as administrative agent and collateral agent (as amended, amended and restated, supplemented or otherwise modified prior to the date hereof, the “MidCap Term Credit Agreement”) and repay in full the outstanding amounts, and terminate the outstanding commitments, under that certain Amended and Restated Credit and Security Agreement (Revolving Loan), dated as of July 1, 2019, by and among the Company, certain of its wholly owned subsidiaries, the lenders party thereto and MidCap Funding IV Trust, as administrative and collateral agent (as amended, amended and restated, supplemented or otherwise modified prior to the date hereof, the “MidCap Revolving Credit Agreement”).

The Restated Agreement also provides for the issuance of warrants to purchase Common Stock (the “Warrants”) to the extent that the obligations under Restated Agreement and the Convertible Notes are prepaid. If issued, the Warrants will be exercisable on a cash or cashless (net exercise) basis with an initial exercise price equal to the conversion price of the Original Note and 2022 Note, respectively, for the number of Conversion Shares (as defined in the Convertible

Notes) which the repaid amount would have been convertible into and will be subject to the Beneficial Ownership Cap, as well as certain other customary anti-dilution adjustments upon the occurrence of certain events such as stock splits, subdivisions, reclassifications or combinations of Common Stock consistent with those included in the Convertible Notes. The Warrants will also provide, at the election of each holder thereof, for the payment of the exercise price therefor by reduction of the principal amount of any outstanding Convertible Notes held by such holder. Upon the consummation of a “Major Transaction” (as defined in the Warrants and consistent with the term as used in the Convertible Notes), holders of the Warrants may elect to (i) have their Warrants redeemed by the Company for an amount equal to the Black-Scholes value of such Warrant, in cash or, if applicable, in the form of the consideration paid to the Company’s stockholders in a Major Transaction, or (ii) have such Warrants be assumed by the successor to the Company in a Major Transaction, if applicable. Holders of the Warrants are also entitled to participate in any dividends or distributions to holders of Common Stock at the time such dividends or distributions are paid to such stockholders. All Warrants under the Exchange Agreement with Deerfield, in connection with the Restated Agreement were exercised as of March 31, 2023. See Note 8 for additional details.

The Company may redeem all or any portion of the principal amount of the Convertible Notes for cash. Upon redemption of any Convertible Notes, the Company will issue Warrants covering the same number of shares of Common Stock underlying, and at an exercise price equal to the conversion price of, the redeemed Convertible Notes. The Convertible Notes provide for the optional redemption of the Convertible Notes without issuance of any Warrants or payment of any additional make whole amount (unless such Convertible Note is converted following receipt of an optional redemption notice but prior to payment of the redemption amount) provided that each of the following is greater than 130% of the conversion price then in effect.(1) the volume weighted average price of the Common Stock on each of any twenty (20) trading days during the period of thirty (30) consecutive trading days ending on the date on which the Company delivers an optional redemption notice, (2) the volume weighted average price of the Common Stock on the last trading day of such period and (3) the closing price of the Common Stock on the last trading day of such period. The Company may not effect any optional redemption during a delisting event or unless all conversion shares and warrant shares are freely tradable.

 

 

As of March 31, 2023, there was $73.5 million of outstanding principal, reduced by unamortized debt discount and issuance costs of $16.9 million related to the convertible note included in “Long-term debt” on the consolidated balance sheet. The Company amortizes the debt discount and debt issuance costs under the effective interest method over the term of the Note, at a resulting effective interest rate of approximately 12%. For the three months ended March 31, 2023 and 2022, the amortization of the convertible debt discount and issuance costs were $1.2 million and $0.8 million, respectively. Both were included in interest expense in the condensed consolidated statements of operations.

The Company is subject to a number of affirmative and restrictive covenants, including covenants regarding compliance with applicable laws and regulations, maintenance of property, payment of taxes, maintenance of insurance, business combinations, incurrence of additional indebtedness, prepayments of other unsecured indebtedness and transactions with affiliates, among other covenants.

Net Loss Per Share

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 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 dilutive shares consist of shares that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. 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 (in thousands, except per share and share amounts).

Product Liability Litigation

 

On October 7, 2019, a lawsuit was filed in the Superior Court of the State of California against the Company and Silimed Industria de Implantes Ltda. (the Company’s former contract manufacturer). The lawsuit alleges that the Company’s textured breast implants caused certain of the plaintiffs to develop a condition known as breast implant associated anaplastic large cell lymphoma (“BIA-ALCL”), and that the Company is liable to the plaintiffs based on claims for strict liability (failure to warn), strict liability (defective manufacture), negligence and loss of consortium. On January 21, 2020, the Company filed a demurrer to the plaintiff’s complaint, which demurrer the Court granted in a tentative ruling dated March 9, 2021 with leave to replead. The Plaintiffs filed an amended complaint on April 6, 2021 and the Company filed a demurrer to that complaint on May 6, 2021. On October 25, 2021, the Court issued a ruling granting the Company’s demurrer in-part and denying it in-part, and gave plaintiffs twenty days to file an amendment complaint. On August 3, 2022, the Company entered into confidential settlement agreements with the plaintiffs resolving all disputes between them and dismissing the plaintiffs’ claims with prejudice. The Court granted the dismissal with prejudice on August 4, 2022.

On September 23, 2020, a lawsuit was filed in the Eastern District of Tennessee against the Company. The lawsuit alleges that the Company’s textured breast implants caused certain of the plaintiffs to develop a condition known as breast implant associated anaplastic large cell lymphoma (“BIA-ALCL”), and that the Company is liable to the plaintiffs based on claims for negligence, strict liability (manufacturing defects), strict liability (failure to warn), breach of express and implied warranties, and punitive damages. The Company filed a motion to dismiss the complaint on December 7, 2020. On February 28, 2022 the Court granted the Company’s motion, and dismissed the plaintiff’s complaint with prejudice. On March 28, 2022, the plaintiffs filed a motion to alter or amend the judgment. The Company opposed that motion on April 11, 2022. On March 31, 2023 the Court denied plaintiffs motion.

 

Grand Jury and SEC Subpoenas

The Company received a grand jury subpoena dated September 30, 2022 from the U.S. Department of Justice (“DOJ”) requesting the production of materials concerning the trading activities of a former Chief Executive Officer of the Company in 2019 and 2020, including all documents and communications with the General Counsel regarding such activities. In addition, the SEC has subpoenaed documents and testimony from each of the Company and its General Counsel. Each of the SEC subpoenas is captioned “In the Matter of Trading in the Securities of Sientra, Inc.” The SEC subpoenas request, among other things, documents and communications relating to trading activities by each of the aforementioned individuals. The investigation by the SEC does not mean that the SEC has concluded that anyone has violated the law. Also, the investigation does not mean that the SEC has a negative opinion of any person, entity or security. In April 2023, the DOJ informed the Company that the DOJ did not intend to pursue prosecutions relating to the subpoena and was closing its file with respect to the Company. The Company continues to cooperate with the SEC. The Company is, at this time, unable to predict what action, if any, might be taken in the future by the SEC as a result of the matters that are the subject of the subpoenas and investigation.

Basis of Presentation
a.
Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Sientra, Inc. (“Sientra”, the “Company”, “we”, “our”, or “us”) in this Quarterly Report on Form 10-Q have been prepared in accordance with U.S. generally accepted accounting principles, or "GAAP", and the rules and regulations of the U.S. Securities and Exchange Commission, or the "SEC". Accordingly, they do not include certain notes and financial presentations normally required under GAAP 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, 2022 filed with the SEC on April 18, 2023, or the Annual Report. The results for the three months ended March 31, 2023 are not necessarily indicative of results to be expected for the year ending December 31, 2023, any other interim periods, or any future year or period.

 

Reverse Stock Split

 

On January 19, 2023, the Company effected a 1-for-10 reverse stock split (the “Reverse Stock Split”) of the Company’s issued and outstanding common stock, par value $0.01 per share (the “Common Stock”). by the filing of a Certificate of Amendment (the “Certificate”) with the Secretary of State of the State of Delaware pursuant to the Delaware General Corporation Law. The Reverse Stock Split became effective on January 19, 2023.

 

As a result of the Reverse Stock Split, every 10 shares of Common Stock issued and outstanding were automatically reclassified into one new share of common stock. The Reverse Stock Split did not modify any rights or preferences of the shares of Common Stock. Proportionate adjustments will be made to the exercise or conversion prices and the number of shares underlying the Company’s outstanding equity awards, convertible securities and warrants, as well as to the number of shares issued and issuable under the Company’s equity incentive plans. The Common Stock issued pursuant to the Reverse Stock Split will remain fully paid and non-assessable. The Reverse Stock Split will not affect the number of authorized shares of Common Stock or the par value of the Common Stock. All share information in the accompanying financial statements has been adjusted to reflect the results of the Reverse Stock Split.

 

Discontinued Operations of miraDry

As a result of the miraDry sale discussed in Note 2, the miraDry business met the criteria to be reported as discontinued operations. Therefore, the Company is reporting the historical results of miraDry, including the results of operations, cash flows, and related assets and liabilities, as discontinued operations for all periods presented herein through the date of the Sale. Unless otherwise noted, the accompanying notes to the unaudited condensed consolidated financial statements have all been revised to reflect continuing operations only. Following the sale the Company has one operating segment in continuing operations named Plastic Surgery, formerly known as Breast Products.

Liquidity and Going Concern
b.
Liquidity and Going Concern

 

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared assuming the Company will continue as a going concern and in accordance with generally accepted accounting principles in the United States of America. The going concern basis of presentation assumes that the Company will continue in operation one year after the date these financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business.

Pursuant to the requirements of the Financial Accounting Standards Board’s Accounting Standards Codification (“ASC”) Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these condensed consolidated financial statements are issued. This evaluation does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within control of the Company as of the date the condensed consolidated financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued.

Since the Company’s inception, it has incurred recurring losses and cash outflows from operations and the Company anticipates that losses will continue in the near term. During the three months ended March 31, 2023, the Company incurred net losses of $12.9 million and used $6.7 million of cash from continuing operations. As of March 31, 2023, the Company had cash and cash equivalents of $19.4 million. As a result of these conditions substantial doubt exists about our ability to continue as a going concern for a period of at least one year from the date of issuance of these unaudited condensed consolidated financial statements. The unaudited condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

 

In an effort to alleviate these conditions, management is currently evaluating various cost-saving measures in order to reduce operating expenses and cash outflows. However, the Company will need to generate a significant increase in net sales to further improve profitability and cash inflows, which is dependent upon continued growth in our Plastic Surgery segment and the launch of new products and partnerships. Additionally, we are evaluating various funding alternatives to improve liquidity and may seek to raise additional equity or debt capital, refinance our debt obligations or obtain waivers, and/or scale back or freeze our organic growth plans to manage our liquidity and capital resources. As the Company seeks additional sources of financing, there can be no assurance that such financing would be available to the Company on favorable terms or at all. The Company’s ability to obtain additional financing in the equity capital markets is subject to several factors, including market and economic conditions, the Company’s performance and investor sentiment with respect to the Company and its industry.

 

During 2022, to fund ongoing operating and capital needs, the Company raised additional capital through the sale of equity securities and incremental debt financing. See Note 7 to the condensed consolidated financial statements for further details.

Recently Adopted Accounting Standards

 

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. The amendment eliminates certain accounting models and simplifies the accounting for convertible instruments and enhances disclosures for convertible instruments and earnings per share. The amendments are effective for public entities excluding smaller reporting companies for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023 including interim periods within those fiscal years and early adoption is permitted. The Company adopted this guidance effective January 1, 2023 under the modified retrospective adoption approach and there was no material impact on its 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 the ASU 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.
Risks and Uncertainties
d.
Risks and Uncertainties

 

The COVID-19 pandemic and its related macroeconomic effects significantly impacted our business and results of operations in past years. At the height of the pandemic and as an aesthetics company, the surgical procedures involving our breast products were susceptible to local and national government restrictions. The inability or limited ability to perform non-emergency procedures significantly harmed our revenues since the second quarter of 2020 and during the first quarter of 2022.

In addition, the global economy, including the financial and credit markets, has recently experienced extreme volatility and disruptions, including increases to inflation rates, rising interest rates, declines in consumer confidence, declines in economic growth, and uncertainty about economic stability. The severity and duration of the impact of these conditions on our business cannot be predicted.

The estimates used for, but not limited to, determining the collectability of accounts receivable, fair value of long-lived assets and goodwill, and sales returns liability required could be impacted by the factors described above. While the full impact and duration of the factors noted above 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.
