2. Liquidity and Going Concern

2. Liquidity and Going Concern

The accompanying condensed consolidated unaudited financial statements have been prepared assuming the Company will continue to operate as a going concern, which contemplates the realization of assets and settlement of liabilities in the normal course of business, and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from uncertainty related to its ability to continue as a going concern.

The Company has generated limited revenues, has incurred operating losses since inception, and expects to continue to incur significant operating losses for the foreseeable future and may never become profitable. As of March 31, 2022, the Company had $61.8 million in cash and an accumulated deficit of $155.2 million. The Company has historically funded its operations through the issuance of convertible notes (see Note 9), the sale of common stock (see Note 6) and exercises of warrants (see Note 10).

On May 24, 2021, the Company completed an underwritten public offering, pursuant to which the Company sold 22,258,066 shares of its common stock, at a price to the public of $3.10 per share, which included the exercise in full by the underwriter of its option to purchase up to 2,903,226 additional shares of common stock. The net proceeds to the Company from the offering were approximately $64.5 million, after deducting underwriting discounts and commissions and other offering costs. The Company used $7.3 million of the net proceeds from the offering for the partial repayment of certain outstanding convertible promissory notes.

On January 28, 2021, the Company completed an underwritten public offering, pursuant to which the Company sold 17,530,488 shares of its common stock, at a price to the public of $2.05 per share, which included the exercise in full by the underwriter of its option to purchase up to 2,286,585 additional shares of common stock. The net proceeds to the Company from the offering were approximately $33.5 million, after deducting underwriting discounts, commissions and other offering costs. The Company used $3.8 million of the net proceeds from the offering for the partial repayment of certain outstanding convertible promissory notes.

The Company currently has an effective shelf registration statement on Form S-3 filed with the Securities and Exchange Commission (the “SEC”). The Company may use the shelf registration statement on Form S-3 to offer from time to time any combination of debt securities, common and preferred stock and warrants. As of March 31, 2022, the Company had approximately $95.1 million available under its Form S-3 shelf registration statement. The Company also has the ability to raise funds through other means, such as through the filing of a registration statement on Form S-1 or in private placements. The rules and regulations of the SEC or any other regulatory agencies may restrict the Company’s ability to conduct certain types of financing activities or may affect the timing of and amounts it can raise by undertaking such activities.

The Company evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern within one year beyond the filing of this Quarterly Report on Form 10-Q. Based on such evaluation and the Company’s current plans (including the ongoing clinical programs for SLS-002, SLS-005, and other product candidates), which are subject to change, management believes that the Company’s existing cash and cash equivalents as of March 31, 2022 are not sufficient to satisfy its operating cash needs for the year after the filing of this Quarterly Report on Form 10-Q.

The Company’s future liquidity and capital funding requirements will depend on numerous factors, including:

• its ability to raise additional funds to finance its operations;

• its ability to maintain compliance with the listing requirements of the Nasdaq Capital Market;

• the outcome, costs and timing of clinical trial results for the Company’s current or future product candidates;

• potential litigation expenses;

• the emergence and effect of competing or complementary products or product candidates;

• its ability to maintain, expand and defend the scope of its intellectual property portfolio, including the amount and timing of any payments the Company may be required to make, or that it may receive, in connection with the licensing, filing, prosecution, defense and enforcement of any patents or other intellectual property rights;

• its ability to retain its current employees and the need and ability to hire additional management and scientific and medical personnel;

• the terms and timing of any collaborative, licensing or other arrangements that it has or may establish;

• the trading price of its common stock; and

• its ability to increase the number of authorized shares outstanding to facilitate future financing events.

The Company may raise substantial additional funds, and if it does so, it may do so through one or more of the following: issuance of additional debt or equity and/or the completion of a licensing or other commercial transaction for one or more of the Company’s product candidates. If the Company is unable to maintain sufficient financial resources, its business, financial condition and results of operations will be materially and adversely affected. This could affect future development and business activities and potential future clinical studies and/or other future ventures. Failure to obtain additional equity or debt financing will have a material, adverse impact on the Company’s business operations. There can be no assurance that the Company will be able to obtain the needed financing on acceptable terms or at all. Additionally, equity or convertible debt financings will likely have a dilutive effect on the holdings of the Company’s existing stockholders.
