Organization and Description of Business

1.	ORGANIZATION AND DESCRIPTION OF BUSINESS

Mohawk Group Holdings, Inc. and subsidiaries (“Mohawk” or the “Company”) is a rapidly growing technology-enabled consumer products company that uses machine learning, and data analytics to design, develop, market and sell products. Mohawk predominately operates through online retail channels such as Amazon, eBay, and Walmart.

Headquartered in New York, Mohawk’s offices can be found in China, Philippines, Israel, Poland, and the United States.

Merger—On September 4, 2018, pursuant to an Agreement and Plan of Merger and Reorganization among the Company, MGH Merger Sub, Inc. and Mohawk Group, Inc. (“MGI”), as amended by Amendment No. 1 dated as of April 1, 2018 (the “Merger Agreement”), MGI merged with Merger Sub, Inc., with MGI remaining as the surviving entity and becoming a wholly-owned operating subsidiary of the Company (the “Merger”). The Merger was a reverse recapitalization for financial reporting purposes. The Merger is reflected in the financial statements and financial disclosures as if the merger was effective on January 1, 2017. Operations prior to the Merger are the historical operations of MGI.

Under the Merger Agreement, all outstanding common shares, preferred shares and warrants, excluding MGI’s Series C preferred stock (“Series C”) and warrants for Series C, converted to new common shares of the Company at a ratio of 1 to 0.3131 (“the Conversion”). All outstanding Series C, including any warrants for Series C converted on a one to 0.2564 basis to new common shares of the Company. At the time of the merger, the Company had 0.9 million shares outstanding held by certain Series C holders.

Initial Public Offering—On June 14, 2019, the Company completed its initial public offering (“IPO”), selling 3,600,000 shares of common stock at a public offering price of $10.00 per share. Net proceeds to the Company from the offering were approximately $29.6 million, after deducting legal, underwriting and other offering expenses.

Liquidity, Going Concern and Initial Public Offering—The Company is an early-stage growth company. As a result, the Company is investing in launching new products, advancing its software, and its sales and distribution infrastructure to accelerate revenue growth and scale operations to support such growth. To fund this investment, the Company has incurred losses with the expectation that it will generate profitable revenue streams in the future. While management and the Company’s board of directors believes that the Company will eventually reach a scale where the growth of its product revenues will offset the continued investments required in launching new products, completing the development of its software, and managing its sales and distribution operations, they believe that the size and nascent stage of the Company’s target market justify continuing to invest in growth at the expense of short-term profitability.

In pursuit of the foregoing growth strategy, the Company incurred operating losses of $22.6 million and $29.4 million for the years ended December 31, 2017 and 2018, respectively, primarily due to the impact from its continued investment in launching new products, advancing its AIMEE software platform and building out its sales and distribution infrastructure. In addition, at December 31, 2017 and 2018, the Company had an accumulated deficit of $39.2 million and $71.0 million , respectively, cash on hand amounted to $5.3 million and $20.0 million, respectively, total outstanding borrowings from lenders amounted to $10.3 million and $27.5 million, respectively, and total available capacity on borrowings amounted to $5.6 million and $1.4 million at December 31, 2017 and 2018, respectively. Moreover, the Company has not had a sufficient track record of improvement of its operating cash outflows. As such, in the event that the Company was unsuccessful in its ability to continue to reduce its cash outflows or obtain additional financing if such reduction in cash outflows was not achieved, the Company would have been unable to meet its obligations as they became due within one year from the date these condensed consolidated financial statements were issued. These negative financial conditions raised substantial doubt about the Company’s ability to continue as a going concern.

Management plans to continue pursuing its growth strategy. In the past, the Company has successfully funded its losses to-date through equity financings, beginning in July 2014. As of December 31, 2018, the Company has raised over $72.6 million in equity financing to fund its operations since inception. Further, in October 2017, the Company improved its working capital flexibility by securing an up to $30.0 million credit facility and a $7.0 million term loan with MidCap Financial Trust (“MidCap”) and in November 2018, the Company exited the original credit facility with MidCap and entered into a new three-year, $25.0 million revolving credit facility with MidCap, which can be increased, subject to certain conditions, to $50.0 million. Furthermore, on December 31, 2018, the Company entered into a new term loan agreement with Horizon Technology Finance Corporation (“Horizon”) obtaining a five-year, $15.0 million term loan and repaying the outstanding amount of MidCap’s term loan of approximately $4.9 million. While there was no assurance that future investments in the Company’s equity or issuances of debt will occur, management believes its success in obtaining funding since inception will continue in the foreseeable future.

During the Company’s December 31, 2018 audit of its consolidated financial statements, the Company’s financial forecast for the next 12 months included revenue growth, margin expansion, a reduction of certain fixed costs, an improvement in inventory management, and reduction in operating cash deficit. In addition, management anticipated that the Company would not breach its financial covenants associated with its existing credit facility or term loan for the next twelve months. However, there was no assurance that management’s forecast would be attained to maintain its liquidity to fund operations and/or maintain compliance with its covenants without future investments in the Company’s equity or issuance of debt from outside sources. In the event of a breach of the Company’s financial covenants under the credit facility and/or its term loan, outstanding borrowings would become due on demand absent a waiver from the lenders.

These condensed consolidated financial statements have been prepared on the basis that the Company will continue to operate as a going concern and as such, include no adjustments that might be necessary in the event that the Company was unable to operate on this basis.

For the three and six months ended June 30, 2019, the Company incurred operating losses of $6.3 million and $13.5 million, respectively. As of June 30, 2019, the Company had accumulated deficit of $87.0 million, cash on hand of $39.5 million, and total outstanding borrowing from lenders of $31.9 million with a total available capacity on borrowings of $1.1 million. On June 14, 2019, the Company completed its IPO, raising approximately $29.6 million after deducting legal, underwriting and other offering expenses. As of June 30, 2019, the Company has raised over $102.3 million in equity financing to fund its operations since inception, including the net proceeds from the IPO.

The Company believes that, based on its current sales and expense level projections, the credit facility with MidCap (see Note 6), and the proceeds from the IPO, the Company will satisfy its estimated liquidity needs for the twelve months from the condensed consolidated financial statements issuance date. As such, the substantial doubt raised by the Company’s historical operating results has been mitigated.

Summary of Significant Accounting Policies

2.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation—The accompanying unaudited condensed consolidated financial statements have been prepared by the Company in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial reporting and as required by Rule 10-01 of Regulation S-X. In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of items of a normal and recurring nature) necessary to present fairly the financial position as of June 30, 2019, the results of operations for the three and six months ended June 30, 2018 and 2019 and cash flows for the six months ended June 30, 2018 and 2019. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results to be expected for the full year.

The condensed consolidated balance sheet as of December 31, 2018 included herein was derived from the Company’s audited consolidated financial statements as of that date, but does not include all of the information and notes required by GAAP for complete financial statements. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2018, included in the Company’s final prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”), on June 13, 2019 (the “Prospectus”).

Use of Estimates—Preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period covered by the financial statements and accompanying notes. The most significant estimates relate to the determination of fair value of the Company’s common stock and stock-based compensation, prior to the Company’s IPO. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, and makes adjustments when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ from those estimates.

Principles of Consolidation—The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation.

Revenue Recognition—The Company accounts for revenue in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) Topic 606, Revenue from Contracts with Customers.

The Company derives its revenue from the sale of consumer products. The Company sells its products directly to consumers through online retail channels and through wholesale channels.

For direct to consumer sales, the Company considers customer order confirmations to be a contract with the customer. Customer confirmations are executed at the time an order is placed through third party online channels. For wholesale sales, the Company considers the customer purchase order to be the contract.

For all of the Company’s sales and distribution channels, revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied), which typically occurs at shipment date. As a result, the Company has a present and unconditional right to payment and record the amount due from the customer in accounts receivable.

Revenue from consumer product sales is recorded at the net sales price (transaction price), which includes an estimate of future returns based on historical return rates. There is judgment in utilizing historical trends for estimating future returns. The Company’s refund liability for sales returns was $0.3 million and $0.5 million at December 31, 2018 and June 30, 2019, respectively, which is included in accrued liabilities and represents the expected value of the refunds that will be due to its customers.

The Company evaluated principal versus agent considerations to determine whether it is appropriate to record platform fees paid to Amazon as an expense or as a reduction of revenue. Platform fees are recorded as sales and distribution expense and are not recorded as a reduction of revenue because the Company owns and controls all the goods before they are transferred to the customer. The Company can, at any time, direct Amazon and similarly with other third party logistics providers (“Logistics Providers”), to return the Company’s inventory to any location specified by the Company. Any returns made by customers directly to Logistics Providers are the responsibility of the Company to make customers whole and the Company retains the back-end inventory risk. Further, the Company is subject to credit risk (i.e., credit card chargebacks), establishes the prices of its products, can determine who fulfills the goods to the customer (Amazon (or any other Logistics Provider) or the Company) and can limit quantities or stop selling the goods at any time. Based on these considerations, the Company is the principal in this arrangement.

Performance Obligations. A performance obligation is a promise in a contract to transfer a distinct good to the customer and is the unit of account in ASC Topic 606. A contract’s transaction price is recognized as revenue when the performance obligation is satisfied. Each of the Company’s contracts have a single distinct performance obligation, which is the promise to transfer individual goods.

For consumer product sales, the Company has elected to treat shipping and handling as fulfillment activities, and not a separate performance obligation. Accordingly, the Company recognizes revenue for its single performance obligation related to product sales at the time control of the merchandise passes to the customer, which is generally at the time of shipment. The Company bills customers for charges for shipping and handling on certain sales and such charges are recorded as part of net revenue. Shipping and handling revenue for the three and six months ended June 30, 2018 and 2019 were less than $0.1 million and $0.1 million, respectively.

For each contract, the Company considers the promise to transfer products to be the only identified performance obligation. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled.

All of the Company’s revenues as reflected on the condensed consolidated statements of operations for the three and six months ended June 30, 2018 and 2019 are recognized at a point in time.

Sales taxes. Consistent with prior periods, sales taxes collected from customers are presented on a net basis and as such are excluded from net revenue.

Net Revenue by Category. The following table sets forth the Company’s net revenue disaggregated by sales channel and geographic region based on the billing addresses of its customers:

Fair Value of Financial Instruments—The Company’s financial instruments, including net accounts receivable, accounts payable, and accrued and other current liabilities are carried at historical cost. At June 30, 2019, the carrying amounts of these instruments approximated their fair values because of their short-term nature. The credit facility is carried at amortized cost and at December 31, 2018 and June 30, 2019, respectively, the carrying amount approximates fair value as the stated interest rate approximates market rates currently available to the Company. The Company estimates the fair value of the borrowings under our Horizon Term Loan to be approximately $14.7 million and $14.7 million at December 31, 2018 and June 30, 2019, respectively. The Company considers the inputs utilized to determine the fair value of the borrowings to be Level 2 inputs. The Company’s financial instruments of cash and restricted cash consist of Level 1 assets at June 30, 2019. The Company’s cash and restricted cash was approximately $40.0 million and included savings deposits and overnight investments at June 30, 2019.

Assets and liabilities recorded at fair value on a recurring basis in the condensed consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability 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. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:

Level 1—Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date;

Level 2—Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities; and

Level 3—Unobservable inputs that are supported by little or no market data for the related assets or liabilities.

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Recent Accounting Pronouncements

The Jumpstart Our Business Startups Act of 2012 permits an emerging growth company to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. The Company has elected to use this extended transition period until it is no longer an emerging growth company or until it affirmatively and irrevocably opts out of the extended transition period. As a result, the Company’s financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

Adopted Accounting Standards

In November 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-18, Statement of Cash Flows: Restricted Cash (Topic 230) (“ASU 2016-18”). ASU 2016-18 requires that the statement of cash flows explains the change during the period in the total cash and restricted cash. Therefore, amounts generally described as restricted cash should be included with cash when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. ASU 2016-18 requires retrospective application for all periods presented and as a result the Company has recasted its condensed statement of cash flows for the six months ended June 30, 2018 to reflect the adoption of ASU 2016-18, which was implemented on January 1, 2019.

In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718) Scope of Modification Accounting, which provides guidance on the various types of changes which would trigger modification accounting for share-based payment awards. In summary, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The guidance is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. The amendments are applied prospectively to awards modified on or after the adoption date. The new guidance was adopted on January 1, 2019 with no material impact on the condensed consolidated financial statements.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which requires lessees to record most leases on their balance sheets but recognize the expenses on their income statements in a manner similar to current practice. ASU 2016-02 states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. This ASU is effective for all annual reporting periods beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements.

In February 2018, the FASB issued ASU No. 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220) (“ASU 2018-02”). ASU 2018-02 addresses the effect of the change in the U.S. federal corporate tax rate due to the enactment of the December 22, 2017 Tax Act on items within accumulated other comprehensive income (loss). The guidance will be effective for all annual reporting periods beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements.

On August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which changes the fair value measurement disclosure requirements of ASC Topic 820. The amendments in this ASU are the result of a broader disclosure project called FASB Concepts Statement, Conceptual Framework for Financial Reporting—Chapter 8: Notes to Financial Statements. This ASU is effective for all annual reporting periods beginning after December 15, 2019, including interim periods therein. Early adoption is permitted for any eliminated or modified disclosures upon issuance of this ASU. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements.

In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-based Payment Accounting, which expands the scope of ASC Topic 718, Compensation—Stock Compensation, which currently only includes share-based payments issued to employees, to also include share-based payments issued to nonemployees for goods and services. This ASU is effective for all annual reporting periods beginning after December 15, 2019, including interim periods therein. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements.

MidCap Credit Facility and Term Loan

On October 16, 2017, the Company entered into a three-year, $15.0 million revolving credit facility (the “Prior Credit Facility”) with MidCap pursuant to a credit and security agreement (the “Credit and Security Agreement”). As part of the Credit and Security Agreement, the Company also obtained a three-year, $7.0 million term loan with MidCap (the “Prior Term Loan”). On November 23, 2018, the Company exited the Prior Credit Facility with MidCap and entered into a new three-year $25.0 million revolving credit facility (the “Credit Facility”) with MidCap. The Credit Facility can be increased, subject to certain conditions, to $50.0 million. Loans under the Credit Facility are determined based on percentages of the Company’s eligible accounts receivable and eligible inventory. The Credit Facility bears interest at LIBOR plus 5.75% for outstanding borrowings. The Company is required to pay a facility availability fee of 0.5% on the average unused portion of the facility. The Credit Facility contains a minimum liquidity financial covenant that requires the Company to maintain a minimum of $5.0 million in cash on hand or availability in the Credit Facility. In 2018, the Company incurred approximately $1.3 million in debt issuance costs which has been offset against the debt and will be expensed over the three years. Unamortized debt issuance costs of $0.7 million, relating to the Prior Credit Facility, will be amortized in accordance with the terms of the Credit Facility. As of December 31, 2018, there was $16.5 million outstanding on the Credit Facility and an available balance of approximately $1.4 million. As of June 30, 2019, there was $20.4 million outstanding on the Credit Facility and an available balance of approximately $1.1 million. As of June 30, 2019, the Company was in compliance with the financial covenants contained within the Credit Facility.

The Company recorded interest expense from the credit facilities of approximately $0.3 million and $0.8 million for the three months ended June 30, 2018 and 2019, respectively, which included $0.1 million and $0.2 million, respectively, relating to debt issuance costs. The Company recorded interest expense from the credit facilities of approximately $0.6 million and $1.5 million for the six months ended June 30, 2018 and 2019, respectively, which included $0.2 million and $0.4 million, respectively, relating to debt issuance costs.

The Company recorded interest expense from the Prior Term Loan of $0.2 million and $0.5 million for the three and six months ended June 30, 2018, which included less than $0.1 million and less than $0.1 million relating to debt issuance costs, respectively.

On December 31, 2018, the Company repaid the Prior Term Loan with MidCap for $4.9 million as part of the entry into a new term loan with Horizon, including $0.1 million of a prepayment penalty.

Horizon Term Loan

On December 31, 2018, the Company entered into a new term loan agreement with Horizon (the “Horizon Loan Agreement”). As part of the agreement, the Company obtained a five-year $15.0 million term loan (the “Term Loan”). The Term Loan bears interest at 9.90% plus the amount by which one-month LIBOR (or, if LIBOR is no longer widely used or available, a successor benchmark rate, which successor rate shall be applied in a manner consistent with market practice, or if there is no consistent market practice, such successor rate shall be applied in a manner reasonably determined by Horizon) exceeds 2.50% for outstanding borrowings and payments on principal are made on a monthly basis. The maturity date of the Term Loan is January 2023. The Term Loan contains minimum required EBITDA financial covenants that require the Company to achieve EBITDA of certain amounts based on the amount that the Company is permitted to borrow under the Credit Facility (the “Revolving Line Indebtedness Cap”). The Horizon Loan Agreement also contains a cash collateral covenant that requires the Company to maintain a cash collateral account with an amount based on the Revolving Line Indebtedness Cap.

In connection with the Horizon Term Loan Agreement, the Company issued to Horizon warrants to purchase 76,923 shares of its common stock at an exercise price of $15.60 per share. The warrants are exercisable and expire ten years from the date of issuance. The Company utilized the Binomial option-pricing model to determine the fair value of the warrants. The fair value of the warrants on issuance was $0.9 million, which has been recorded as a debt discount against the Term Loan.

The Company incurred approximately $1.0 million in debt issuance costs which has been offset against the debt and will expense over the five years.

The Credit Facility and the Term Loan contain a minimum liquidity covenant that requires the Company to maintain at minimum $5.0 million in unrestricted cash at all times, subject to increases based on amounts drawn. Further, there are additional covenants that, among other things, restrict the ability of the Company and certain of its subsidiaries to (i) incur, assume or guarantee additional indebtedness; (ii) pay dividends or redeem or repurchase capital stock; (iii) make other restricted payments; (iv) incur liens; (v) redeem debt that is junior in right of payment to the notes; (vi) sell or otherwise dispose of assets, including capital stock of subsidiaries; (vii) enter into mergers or consolidations; and (viii) enter into transactions with affiliates. These covenants are subject to a number of important exceptions and qualifications.

As of June 30, 2019, there was $15.0 million outstanding on the Term Loan and the Company was in compliance with the financial covenants contained within the loan. The Company recorded interest expense from the Term Loan of $0.5 million and $1.0 million for the three and six months ended June 30, 2019, respectively, which included $0.1 million and less than $0.3 million, respectively, relating to debt issuance costs.

Earnings Per Share [Abstract]

Net Loss per Share

8.	NET LOSS PER SHARE

Basic net loss per share is determined by dividing net loss by the weighted average shares of common stock outstanding during the period. Diluted net loss per share is determined by dividing net loss by diluted weighted average shares outstanding. Diluted weighted average shares reflects the dilutive effect, if any, of potentially dilutive common shares, such as common stock options calculated using the treasury stock method and convertible notes using the “if-converted” method. In periods with reported net operating losses, all common stock options are deemed anti-dilutive such that basic net loss per share and diluted net loss per share are equal.

The Company’s restricted shares are entitled to receive dividends and hold voting rights applicable to the Company’s common stock, irrespective of any vesting requirement. Accordingly, although the vesting commences upon the elimination of the contingency, the restricted shares are considered a participating security and the Company is required to apply the two-class method to consider the impact of the restricted shares on the calculation of basic and diluted earnings per share. The Company is currently in a net loss position and is therefore not required to present the two-class method; however, in the event the Company is in a net income position, the two-class method must be applied by allocating all earnings during the period to common shares and restricted shares.

The following table sets forth the computation of basic and diluted net loss per share (in thousands, except per share data):

The Company does not believe that the final outcome of these matters will have a material adverse effect on the Company’s condensed consolidated financial position or results of operations. In addition, the Company maintains what it believes is adequate insurance coverage to further mitigate risk. However, no assurance can be given that the final outcome of such proceedings will not materially impact the Company’s condensed consolidated financial condition or results of operations. Further, no assurance can be given that the amount or scope of existing insurance coverage will be sufficient to cover losses arising from such matters.

Recall

In April 2018, the Company retained outside counsel to assist it in evaluating a safety issue related to certain hair dryers that it imported and sold through its subsidiaries between 2014 and 2018 (the “Xtava Allure Hair Dryer”). The Company had received communications directly from consumers and identified online reviews of overheating or fires associated with these hair dryers. The Company sold approximately 170,000 net units from the introduction of the product in 2015 through its discontinuance in the first quarter of 2018 totaling approximately $6.2 million in net revenue.

In May 2018 the Company’s board of directors approved a voluntary recall of the Xtava Allure Hair Dryer. In June 2018, the Company filed an application for a voluntary recall with the US Consumer Product Safety Commission (“CPSC”) pursuant to Section 15(b) of the Consumer Product Safety Act (“CPSA”). The Company has received approval from the CPSC to provide consumers with replacement units and publicly announced the recall on August 15, 2018. The Company estimates it will incur approximately $1.6 million in costs related to the recall for procurement, manufacturing, fulfillment and delivery to consumers who apply and qualify for the recall costs. The Company also estimates it will incur legal and other expenses of approximately $0.4 million related to the recall which will be expensed as incurred. The Company has also incurred and settled all but one consumer legal matter related to Xtava Allure Hair Dryer for insignificant amounts. The Company believes the remaining legal matter will be settled for an insignificant amount. As of June 30, 2019, the remaining recall liability is $1.5 million.

Pursuant to the CPSC and the guidelines set forth by the CPSA, a company may be subject to a late reporting investigation when a recall is announced. If a company is deemed to be a late reporter upon investigation by the CPSC, it may be subject to penalties. The Company believes it is likely that the CPSC will launch a discovery process to understand if a late reporting penalty is warranted. The investigation would evaluate a number of statutory and regulatory factors in determining a penalty amount, such as the severity of the risk of injury, the occurrence or absence of injury, the appropriateness of such penalty in relation to the size of the business and other factors. As of the date of issuance of this report, the Company believes it has met all the appropriate reporting requirements. If the Company is determined to have violated the reporting guidelines a penalty may be material to the consolidated financial statements. If CPSC seeks significant civil penalties for late reporting, the Company intends to vigorously defend itself. As of the date of the issuance of these financial statements the Company cannot reasonably estimate what, if any, penalties for potential late reporting may be levied.

Restated Voting Agreement

On November 1, 2018, Dr. Larisa Storozhenko, Maximus Yaney and Asher Maximus I, LLC (the “Initial Designating Parties”) entered into a voting agreement with Mr. Asher Delug, one of the stockholders of the Company and a member of the Company’s board of directors, pursuant to which Mr. Delug will have the power to vote such number of shares of common stock as is equal to: (a) all of the shares of the Company’s common stock beneficially held by the Initial Designating Parties minus (b) such number of shares of common stock representing 19.9% of the total voting power of the Company’s capital stock outstanding with respect to the election of directors, the appointment of officers and any amendments of the Company’s amended and restated certificate of incorporation or amended and restated bylaws (the “Voting Agreement”).

The Voting Agreement was amended and restated pursuant to a new Voting Agreement, dated March 13, 2019, by and among MV II, LLC, Dr. Larisa Storozhenko, Mr. Maximus Yaney, Mr. Delug and the Company (the “Restated Voting Agreement”). Under the Restated Voting Agreement, each of MV II, LLC, Dr. Larisa Storozhenko and Mr. Yaney (collectively, the “Designating Parties”) agreed to relinquish the right to vote their shares of the Company’s capital stock, and any of the Company’s other equity interests (collectively, the “Voting Interests”) by granting the Company’s board of directors the sole right to vote all of the Voting Interests as the Designating Parties’ proxyholder. The Voting Interests include all shares of the Company’s common stock currently held by the Designating Parties, as well as any of the Company’s securities or other equity interests acquired by the Designating Parties in the future. Pursuant to the proxy granted by the Designating Parties, the Company’s board of directors are required to vote all of the Voting Interests in direct proportion to the voting of the shares and equity interests voted by all holders other than the Designating Parties. The proxy granted by the Designating Parties under the Restated Voting Agreement is irrevocable. In addition, the Restated Voting Agreement proxyholder may not be changed unless the Company receives the prior approval of The Nasdaq Stock Market LLC.

Under the Restated Voting Agreement, each of the Designating Parties further agreed not to purchase or otherwise acquire any shares of the Company’s capital stock or other equity securities, or any interest in any of the foregoing.

The Restated Voting Agreement became effective on June 12, 2019 and will continue until the earlier to occur of (a) a Deemed Liquidation Event unless, immediately upon such Deemed Liquidation Event, the Company’s common stock is and remains listed on The Nasdaq Stock Market LLC, or (b) Mr. Yaney’s death. For purposes of the agreement, a “Deemed Liquidation Event” means (i) the acquisition of the Company by another entity by means of any transaction or series of related transactions to which the Company is party other than a transaction or series of transactions in which the holders of the Company’s voting securities outstanding immediately prior to such transaction or series of transactions retain, immediately after such transaction or series of transactions, as a result of the Company’s shares held by such holders prior to such transaction or series of transactions, a majority of the total voting power represented by the Company’s outstanding voting securities or such other surviving or resulting entity; (ii) a sale, lease or other disposition of all or substantially all of the Company’s or its subsidiaries’ assets taken as a whole by means of any transaction or series of related transactions, except where such sale, lease or other disposition is to a wholly-owned subsidiary of the Company; or (iii) any liquidation, dissolution or winding up of the Company, whether voluntary or involuntary; however, a Deemed Liquidation Event shall not include any transaction effected primarily to raise capital for the Company or a spin-off or similar divestiture of the Company’s product or SaaS business as part of reorganization of the Company approved by the Company’s board of directors.

Voting Agreement with Asher Delug

On April 12, 2019, the Company entered into a Voting Agreement with Asher Delug (the “Delug Voting Agreement”). The terms of the Delug Voting Agreement are substantially similar to the terms of the Restated Voting Agreement.

Under the Delug Voting Agreement, Mr. Delug agreed to relinquish his right to vote his shares of the Company’s capital stock, and any of the Company’s other equity interests (collectively, the “Delug Voting Interests”) by granting the Company’s board of directors the sole right to vote all of the Delug Voting Interests as Mr. Delug’s proxyholder. The Delug Voting Interests include all shares of the Company’s common stock currently held by Mr. Delug, as well as any of the Company’s securities or other equity interests acquired by Mr. Delug in the future. Pursuant to the proxy granted by Mr. Delug, the Company’s board of directors are required to vote all of the Delug Voting Interests in direct proportion to the voting of the shares and equity interests voted by all holders other than Mr. Delug. The proxy granted by Mr. Delug under the Delug Voting Agreement is irrevocable. In addition, the Delug Voting Agreement proxyholder may not be changed unless the Company receives the prior approval of The Nasdaq Stock Market LLC.

Under the Delug Voting Agreement, Mr. Delug further agreed not to purchase or otherwise acquire any shares of the Company’s capital stock or other equity securities, or any interest in any of the foregoing.

The Delug Voting Agreement became effective on June 12, 2019 and will continue until the earlier to occur of (a) a Deemed Liquidation Event unless, immediately upon such Deemed Liquidation Event, the Company’s common stock is and remains listed on The Nasdaq Stock Market LLC, or (b) Mr. Delug’s death. For purposes of the agreement, a “Deemed Liquidation Event” has the same meaning as in the Restated Voting Agreement.
