Company Overview

 

We are a late-stage clinical biopharmaceutical company focused on developing novel cancer immunotherapeutics for a broad range of cancer indications. Our product candidates currently include galinpepimut-S and nelipepimut-S.

 

Pipeline

 

Galinpepimut-S, or GPS

 

Our lead product candidate, galinpepimut-S, or GPS, is a cancer immunotherapeutic agent licensed from Memorial Sloan Kettering Cancer Center, or MSK, that targets the Wilms tumor 1, or WT1, protein, which is present in 20 or more cancer types. Based on its mechanism of action as a directly immunizing agent, GPS has potential as a monotherapy or in combination with other immunotherapeutic agents to address a broad spectrum of hematologic, or blood, cancers and solid tumor indications.

 

In January 2020, we commenced a Phase 3 trial for GPS monotherapy in patients with acute myeloid leukemia, or AML, in the maintenance setting after achievement of their second complete remission, or CRem2, following successful completion of second-line antileukemic therapy, which we refer to as the REGAL study. We expect this study will be used as the basis for a Biologics License Application, or BLA, submission, subject to a statistically significant and clinically meaningful data outcome and agreement with the U.S. Food & Drug Administration, or the FDA. The study is expected to enroll approximately 116 patients at approximately 50 clinical sites in the United States and Europe and is contemplated to have a planned interim safety and futility analysis after 80 events (deaths).

 

In December 2018, we initiated a Phase 1/2 multi-arm (“basket” type) clinical study of GPS in combination with Merck & Co., Inc.’s anti-PD-1 therapy, Keytruda® (pembrolizumab). We plan to enroll up to approximately 90 patients at up to 20 centers in the United States. The initial tumor types being studied are ovarian cancer (second or third line) and colorectal cancer (third or fourth line) with up to approximately 40 patients in total in these two indications, to be followed by AML (in patients having achieved partial response as their best hematological response after four cycles of therapy with hypomethylating agents), triple negative breast cancer, or TNBC, (second line), and small cell lung cancer, or SCLC.

 

GPS was granted Orphan Drug Product Designations from the FDA, as well as Orphan Medicinal Product Designations from the European Medicines Agency, or EMA, for GPS in AML, malignant pleural mesothelioma, or MPM, and multiple myeloma, or MM, as well as Fast Track Designation for AML, MPM, and MM from the FDA.

 

Nelipepimut-S or NPS

 

Nelipepimut-S, or NPS, is a cancer immunotherapy targeting the human epidermal growth factor receptor 2, or HER2, expressing cancers. Data presented in 2018 from a Phase 2b clinical trial of the combination of trastuzumab (Herceptin®) plus NPS in HER2 low expressing (1+ or 2+ per immunohistochemistry, or IHC) breast cancer patients in the adjuvant setting to prevent recurrences showed a clinically and statistically significant improvement in the disease-free survival, or DFS, rate for the TNBC cohort at 24 months for patients treated with NPS plus trastuzumab of 92.6% compared to 70.2% for those treated with trastuzumab alone. Following ongoing discussions with the FDA and based upon written feedback from the FDA and on the totality of clinical, safety and translational NPS data to date, we have finalized the design and plan for a Phase 3 registration-enabling study of NPS in combination with trastuzumab for the treatment of patients with TNBC in the adjuvant setting after standard treatment. If successful, we believe this study may be considered as the basis for a BLA submission to the FDA. We are seeking out-licensing opportunities to fund and conduct the future clinical development of NPS in order to maximize the potential of the program and we do not plan to conduct and fund a Phase 3 program for NPS on our own.

 

FBP-targeting bivalent vaccine (GALE-301/-302)

 

In order to prioritize development of our core assets, we have determined to cease development of GALE-301 and GALE-302, cancer immunotherapies that target the E39 peptide derived from the folate binding protein, or FBP, which were licensed in from The Henry M. Jackson Foundation, or HJF, and the MD Anderson Cancer Center, or MDACC. We are currently negotiating a termination of the license agreement with HJF and MDACC.

 

 

 

 

The chart below summarizes the current status of our clinical development pipeline:

 

 

 

Cancer Immunotherapy Market Overview

 

According to a January 2020 report by Kelly Scientific Publications, cancer immunotherapy drugs have already captured nearly 50% of the overall oncology drugs market in 2019, generating about $75 billion in that year alone, and are forecast to surpass $115 billion in 2023. Additionally, an October 2019 Allied Market Research report on the estimated entire market value of oncology drugs (of any type) suggests that cancer immunotherapies could represent up to 77% of that total value by 2023. According to a report published in September 2018, it was projected that approximately 70% of the 2019 immunotherapy market would be comprised of checkpoint inhibitors (~30% of the market share), immune synapse co-stimulators and bispecific monoclonal antibodies (~40% of the market share), as well as approximately 30% of other immunotherapies, including chimeric antigen receptor (CAR) T-cell therapies and other cell-based modalities (e.g., ex vivo modified natural killer or NK cells). It is predicted that the checkpoint inhibitor market share will decrease slightly by 2023, reaching a 27% value (from a 30% value in 2019), as novel therapies, including peptide cancer active immunizers (vaccines) such as our product candidates, GPS and NPS and cell-based therapies, advance into regulatory approvals and use in the cancer market.

 

The total number of newly diagnosed patients with AML per year in the United States is approximately 21,450 (2019 epidemiological data: American Cancer Society). It is estimated that the number of adult patients of any age with AML in the United States per year who successfully enter into CRem2, the indication of our REGAL study, is approximately 2,000 patients and approximately 4,700 patients outside of the United States in the rest of the world, or ROW, while the number of patients who achieve CRem1 is estimated to be approximately 16,400 patients in the United States and approximately 38,100 patients ROW. The number of patients potentially eligible for GPS maintenance therapy after achievement of CRem2 status is approximately 1,200 patients in the United States and approximately 2,800 patients ROW.

 

Recent Developments

 

On March 11, 2020, the World Health Organization declared the outbreak of a new coronavirus to be a “pandemic.” First identified in 2019 and known now as COVID-19, the outbreak has resulted in various “stay-at-home” and “shutdown” orders through the various states in the United States as well as most countries worldwide. The pandemic has impacted millions of individuals and businesses worldwide. As we have functioned operationally as a semi-virtual company, the transition to “work-from home” for our employees has not materially altered our business operations. Our Phase 3 REGAL study is in its early stages, with the necessary work to activate additional sites in the United States and Europe continuing without material interruption. Screening is ongoing at the majority of the sites in the GPS + pembrolizumab combination study although certain sites have limited operations to some extent. Due to the uncertainty of these limitations regarding the sites, we now expect initial clinical data in the first half of 2021. We have been informed by MSK that while it is continuing to dose the patients already enrolled in the MPM IST, it is not currently enrolling additional patients. We believe that the COVID-19 pandemic has not materially impacted our efforts to out-license NPS. The extent to which the coronavirus impacts the Company's operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration of the outbreak, the re-emergence of a second outbreak in the fall or winter, new information which may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, among others. In particular, the continued spread of the coronavirus globally could adversely impact the Company's clinical trial operations and could have an adverse impact on the Company's business and the Company's financial results.

Risks Associated with Our Business

 

Our business is subject to a number of risks of which you should be aware before making an investment decision. These risks are discussed more fully in the “Risk Factors” section of this prospectus immediately following this prospectus summary. These risks include the following:

 

· Our business may be adversely affected by the recent coronavirus outbreak.

 

· We have incurred substantial losses since our inception and anticipate that we will continue to incur substantial and increasing losses for the foreseeable future.

 

· We will need significant additional financing to fund our operations and complete the development and, if approved, the commercialization of our product candidates. If we are unable to raise capital when needed, we could be forced to delay, reduce or eliminate our product development programs or commercialization efforts.

 

· We currently have no source of revenues. We may never generate revenues or achieve profitability.

 

· We expect to continue to incur significant operating and non-operating expenses, which may make it difficult for us to secure sufficient financing and may lead to uncertainty about our ability to continue as a going concern.

 

· We have announced that we are considering strategic alternatives in order to maximize stockholder value. We may not be able to identify or consummate a suitable transaction as a result of this review.

 

· We have been involved in multiple legal and governmental proceedings, and may in the future be involved in proceedings, relating to the commercial activities of our predecessor that could adversely affect our financial condition and our business.

 

· We are dependent on technologies we license, and if we lose the right to license such technologies or we fail to license new technologies in the future, our ability to develop new products would be harmed, and if we fail to meet our obligations under our license agreements, we may lose the ability to develop our product candidates.

 

· We are currently a clinical-stage biopharmaceutical company with product candidates in clinical development. If we are unable to successfully develop and commercialize product candidates or experiences significant delays in doing so, our business may be materially harmed.

 

· Our future success is dependent on the regulatory approval of our product candidates.

USE OF PROCEEDS

 

We will not receive any of the proceeds from the sale of securities by the selling stockholders pursuant to this prospectus. We may receive up to approximately $3.2 million in aggregate gross proceeds from cash exercises of the Warrants, based on the per share exercise price of the Warrants. Any proceeds we receive from the exercise of the Warrants will be used to advance our clinical programs and for general corporate purposes.

 

SELLING STOCKHOLDERS

 

The shares of common stock being offered by the selling stockholders are those issuable upon the exercise of the Warrants. For additional information regarding the issuance of these securities, see “Prospectus Summary—Registered Direct Offering of Common Stock and Concurrent Private Placement of Warrants” on page 3 of this prospectus. We are registering the shares of common stock issuable upon exercise of the Warrants in order to permit the selling stockholders to offer the shares for resale from time to time. Except for the ownership of the Warrants, the transactions contemplated pursuant to the Purchase Agreement and other financings completed by us, the selling stockholders have not had any material relationship with us within the past three years.

 

The following table sets forth certain information with respect to each selling stockholder, including (i) the shares of our common stock beneficially owned by the selling stockholder prior to this offering, (ii) the number of shares being offered by the selling stockholder pursuant to this prospectus and (iii) the selling stockholder’s beneficial ownership after completion of this offering. The registration of the shares of common stock issuable to the selling stockholders upon the exercise of the Warrants does not necessarily mean that the selling stockholders will sell all or any of such shares, but the number of shares and percentages set forth in the final two columns below assume that all shares of common stock being offered by the selling stockholders are sold.

 

The table is based on information supplied to us by the selling stockholders, with beneficial ownership and percentage ownership determined in accordance with the rules and regulations of the SEC, and includes voting or investment power with respect to shares of stock. This information does not necessarily indicate beneficial ownership for any other purpose. In computing the number of shares beneficially owned by a selling stockholder and the percentage ownership of that selling stockholder, shares of common stock subject to warrants held by that selling stockholder that are exercisable within 60 days after May 29, 2020, are deemed outstanding. Such shares, however, are not deemed outstanding for the purposes of computing the percentage ownership of any other person. The percentage of beneficial ownership after this offering is based on 6,717,900 shares of common stock outstanding on May 14, 2020.

 

This prospectus covers the resale of 818,900 shares of our common stock that may be sold or otherwise disposed of by the selling stockholders. Such shares are issuable to the selling stockholders upon the exercise of the Warrants. The Warrants are immediately exercisable on the date of their issuance and expire five and a half (5.5) years from the date they became exercisable. All of the Warrants have an exercise price of $3.93 per share. See “Prospectus Summary —Registered Direct Offering of Common Stock and Concurrent Private Placement of Warrants” above for a complete description of the Warrants. The selling stockholders may sell all, some or none of their shares in this offering, but the number of shares and percentages set forth in the final two columns below assume that all shares of common stock being offered by the selling stockholders are sold. See “Plan of Distribution.”

PLAN OF DISTRIBUTION

 

Each selling stockholder of the securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on The Nasdaq Capital Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A selling stockholder may use any one or more of the following methods when selling securities:

 

· ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

 

· block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

 

· purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

 

· an exchange distribution in accordance with the rules of the applicable exchange;

 

· privately negotiated transactions;

 

· settlement of short sales;

 

· in transactions through broker-dealers that agree with the selling stockholders to sell a specified number of such securities at a stipulated price per security;

 

· through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

 

· a combination of any such methods of sale; or

 

· any other method permitted pursuant to applicable law.

 

The selling stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

 

Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction, a markup or markdown in compliance with FINRA IM-2440.

 

In connection with the sale of the securities or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The selling stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

 

The selling stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each selling stockholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

 

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

 

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the selling stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

 

8 

 

 

Pursuant to applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the selling stockholders or any other person. We will make copies of this prospectus available to the selling stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

DESCRIPTION OF CAPITAL STOCK

 

The following description of our capital stock summarizes the material terms and provisions of our common stock and our preferred stock. For the complete terms of our common stock, please refer to our amended and restated certificate of incorporation and our amended and restated bylaws, each as amended to date, that are incorporated by reference into the registration statement of which this prospectus is a part or may be incorporated by reference into this prospectus. The terms of these securities may also be affected by the Delaware General Corporation Law, or the DGCL. The summary below is qualified in its entirety by reference to our amended and restated certificate of incorporation and amended and restated bylaws, each as in effect at the time of any offering of securities under this prospectus.

 

General

 

Our amended and restated certificate of incorporation authorizes us to issue up to 350,000,000 shares of common stock, $0.0001 par value per share, and 5,000,000 shares of preferred stock, $0.0001 par value per share.

 

As of March 31, 2020, there were:

 

· 6,717,900 shares of common stock outstanding;

 

· 193,520 shares of common stock issuable upon exercise of outstanding options;

 

· 170,000 shares of common stock issuable upon settlement of outstanding RSUs; and

 

· warrants outstanding for the purchase of an aggregate of 1,120,148 shares of common stock;

 

Common Stock

 

Voting

 

Each holder of our common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. Our amended and restated certificate of incorporation and amended and restated bylaws do not provide for cumulative voting rights. Because of this absence of cumulative voting, the holders of a majority of the shares of common stock entitled to vote in any election of directors can elect all the directors standing for election, if they should so choose.

 

Dividends

 

Subject to preferences that may be applicable to any then outstanding shares of preferred stock, holders of common stock are entitled to receive ratably those dividends, if any, as may be declared from time to time by our board of directors out of legally available funds.

 

Liquidation

 

In the event of our dissolution or liquidation, holders of common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all our debts and other liabilities and the satisfaction of any preferential rights that may be granted to the holders of any then outstanding shares of preferred stock.

 

Rights and Preferences

 

Holders of common stock have no preemptive, conversion or subscription rights, and there are no redemption or sinking fund provisions applicable to the common stock. The rights, preferences, and privileges of the holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock.

 

Fully-paid

 

All of the outstanding shares of our common stock are, and the shares of common stock issued upon the conversion of any securities convertible into our common stock will be, fully paid and non-assessable. The shares of common stock offered by this prospectus or upon the conversion of any preferred stock or debt securities or exercise of any warrants offered pursuant to this prospectus, when issued and paid for, will also be, fully paid and non-assessable.

 

Preferred Stock

 

Under our amended and restated certificate of incorporation, our board of directors has the authority, without further action by our stockholders, to issue up to 5,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof. These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of such series, any or all of which may be greater than the rights of common stock. The issuance of our preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change of control of our company or other corporate action.

 

10 

 

 

The following summary of terms of our preferred stock is not complete. You should refer to the provisions of our amended and restated certificate of incorporation and amended and restated bylaws and the resolutions containing the terms of each class or series of the preferred stock which have been or will be filed with the SEC at or prior to the time of issuance of such class or series of preferred stock and described in the applicable prospectus supplement. The applicable prospectus supplement may also state that any of the terms set forth herein are inapplicable to such series of preferred stock, provided that the information set forth in such prospectus supplement does not constitute material changes to the information herein such that it alters the nature of the offering or the securities offered.

 

Our board of directors will fix the designations, voting powers, preferences and rights of the preferred stock of each series we issue under this prospectus, as well as the qualifications, limitations or restrictions thereof, in the certificate of designation relating to that series. We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of any certificate of designation that describes the terms of the series of preferred stock we are offering. We will describe in the applicable prospectus supplement the terms of the series of preferred stock being offered, including, to the extent applicable:

 

· the title and stated value;

 

· the number of shares we are offering;

 

· the liquidation preference per share;

 

· the purchase price;

 

· the dividend rate, period and payment date and method of calculation for dividends;

 

· whether dividends will be cumulative or non-cumulative and, if cumulative, the date from which dividends will accumulate;

 

· the procedures for any auction and remarketing;

 

· the provisions for a sinking fund;

 

· the provisions for redemption or repurchase and any restrictions on our ability to exercise those redemption and repurchase rights;

 

· any listing of the preferred stock on any securities exchange or market;

 

· whether the preferred stock will be convertible into our common stock or other securities, and the conversion rate or conversion price, or how they will be calculated, and the conversion period;

 

· whether the preferred stock will be exchangeable into debt securities, and the exchange rate or exchange price, or how they will be calculated, and the exchange period;

 

· voting rights of the preferred stock;

 

· preemptive rights;

 

· restrictions on transfer, sale or other assignment;

 

· whether interests in the preferred stock will be represented by depositary shares;

 

· a discussion of material or special U.S. federal income tax considerations applicable to the preferred stock;

 

· the relative ranking and preferences of the preferred stock as to dividend rights and rights if we liquidate, dissolve or wind up our affairs;

 

· any limitations on the issuance of any class or series of preferred stock ranking senior to or on parity with the series of preferred stock as to dividend rights and rights if we liquidate, dissolve or wind up our affairs; and

 

· any other specific terms, preferences, rights or limitations of, or restrictions on, the preferred stock.

 

11 

 

 

If we issue shares of preferred stock under this prospectus, they will be validly issued, fully paid and non-assessable.

 

The DGCL provides that the holders of preferred stock will have the right to vote separately as a class on any proposal involving fundamental changes in the rights of holders of such preferred stock. This right is in addition to any voting rights that may be provided for in the applicable certificate of designation.

 

The issuance of our preferred stock could adversely affect the voting power, conversion or other rights of holders of common stock and reduce the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change in control of our company or other corporate action. Additionally, the issuance of preferred stock may have the effect of decreasing the market price of our common stock.

 

Warrants

 

As of March 31, 2020, we had warrants outstanding to purchase 1,120,148 shares of our common stock. 

 

Possible Anti-Takeover Effects of Delaware Law and Our Certificate of Incorporation and Bylaws

 

Provisions of the DGCL and our amended and restated certificate of incorporation and amended and restated bylaws could make it more difficult to acquire our company by means of a tender offer, a proxy contest or otherwise, or to remove incumbent officers and directors. These provisions, summarized below, are expected to discourage certain types of coercive takeover practices and takeover bids that our board of directors may consider inadequate and to encourage persons seeking to acquire control of our company to first negotiate with our board of directors. We believe that the benefits of increased protection of our ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure our company outweigh the disadvantages of discouraging takeover or acquisition proposals because, among other things, negotiation of these proposals could result in an improvement of their terms.

 

Classified Board

 

Our amended and restated certificate of incorporation and our amended and restated bylaws provide that our board of directors is divided into three classes. The directors designated as Class I directors have terms expiring at the annual meeting of stockholders in 2020. The directors designated as Class II directors will have terms expiring at the annual meeting of stockholders in 2021, and the directors designated as Class III directors will have terms expiring at the annual meeting of stockholders in 2022. Directors for each class will be elected at the annual meeting of stockholders held in the year in which the term for that class expires and thereafter will serve for a term of three years. In order to more evenly divide the classes of directors, and consistent with our amended and restated bylaws, John Varian has agreed that, if he is reelected at the 2020 annual meeting as a Class I director, he will resign from his Class I director seat, and the Board will simultaneously appoint him to a newly created directorship in Class III. As a result, Mr. Varian would be up for reelection with other Class III directors at the 2022 annual meeting, rather than with the Class I directors at the 2023 annual meeting.

 

At any meeting of stockholders for the election of directors at which a quorum is present, the election will be determined by a plurality of the votes cast by the stockholders entitled to vote at the election. Under the classified board provisions, it would take at least two elections of directors for any individual or group to gain control of our board. Accordingly, these provisions could discourage a third party from initiating a proxy contest, making a tender offer or otherwise attempting to gain control of our company.

 

Removal of Directors

 

Our amended and restated bylaws provide that our stockholders may only remove our directors with cause.

 

Amendment

 

Our amended and restated certificate of incorporation and our amended and restated bylaws provide that the affirmative vote of the holders of at least 75% of our voting stock then outstanding is required to amend certain provisions relating to the number, term, election and removal of our directors, the filling of our board vacancies, stockholder notice procedures, the calling of special meetings of stockholders and the indemnification of directors. Further, any amendments of our bylaws must be approved by our stockholders as our amended and restated certificate of incorporation does not authorize our board of directors to amend our bylaws.

 

Size of Board and Vacancies

 

Our amended and restated bylaws provide that the number of directors on our board of directors is fixed exclusively by our board of directors. Newly created directorships resulting from any increase in our authorized number of directors will be filled by a majority of our board of directors then in office, provided that a majority of the entire board of directors, or a quorum, is present and any vacancies in our board of directors resulting from death, resignation, retirement, disqualification, removal from office or other cause will be filled generally by the majority vote of our remaining directors in office, even if less than a quorum is present.

 

12 

 

 

Special Stockholder Meetings

 

Our amended and restated certificate of incorporation provides that only the Chairman of our board of directors, our Chief Executive Officer or our board of directors pursuant to a resolution adopted by a majority of the total number of directors we would have if there were no vacancies may call special meetings of our stockholders.

 

Stockholder Action by Unanimous Written Consent

 

Our amended and restated certificate of incorporation expressly eliminates the right of our stockholders to act by written consent.

 

Requirements for Advance Notification of Stockholder Nominations and Proposals

 

Our amended and restated bylaws provide advance notice procedures with respect to stockholder proposals and nomination of candidates for election as directors other than nominations made by or at the direction of board of directors or a committee of our board of directors.

 

No Cumulative Voting

 

The DGCL provides that stockholders are denied the right to cumulate votes in the election of directors unless our certificate of incorporation provides otherwise. Our amended and restated certificate of incorporation does not provide for cumulative voting.

 

Undesignated Preferred Stock

 

The authority that is possessed by our board of directors to issue preferred stock could potentially be used to discourage attempts by third parties to obtain control of our company through a merger, tender offer, proxy contest, or otherwise by making it more difficult or costlier to obtain control of our company. Our board of directors may issue preferred stock with voting rights or conversion rights that, if exercised, could adversely affect the voting power of the holders of common stock.

 

Authorized but Unissued Shares

 

Our authorized but unissued shares of common stock and preferred stock will be available for future issuance without stockholder approval. We may use additional shares for a variety of purposes, including future public offerings to raise additional capital, to fund acquisitions and as employee compensation. The existence of authorized but unissued shares of common stock and preferred stock could render more difficult or discourage an attempt to obtain control of our company by means of a proxy contest, tender offer, merger or otherwise.

 

The above provisions may deter a hostile takeover or delay a change in control or management of our company.

 

Listing on The Nasdaq Capital Market

 

Our common stock is listed on The Nasdaq Capital Market under the symbol “SLS”. On May 27, 2020, the closing price of our common stock was $3.60 per share. As of May 27, 2020, we had approximately 26 stockholders of record.

 

The applicable prospectus supplement will contain information, where applicable, as to other listing, if any, on The Nasdaq Capital Market or other securities exchange of the preferred stock covered by such prospectus supplement.

The transfer agent and registrar for our capital stock is Computershare Trust Company, N.A. Its address is 250 Royall Street, Canton, MA 02021. Its telephone number is (201) 680-4503.
