Business Overview
 
We are developing companion diagnostic tests designed to expand the eligible patient populations for targeted therapies by discovering new cancer sub-types molecular-based approaches cannot detect. Our proprietary CELsignia diagnostic platform is the only commercially ready technology we are aware of that uses a patient’s living tumor cells to identify the specific abnormal cellular process driving a patient’s cancer and the targeted therapy that best treats it. We believe our CELsignia platform provides two important improvements over traditional molecular diagnostics. First, molecular diagnostics can only provide a snapshot of the genetic mutations present in a patient’s tumor because they analyze cell fragments. Using cell fragments prevents molecular diagnostics from analyzing the dynamic cellular activities, known as cell signaling, that regulate cell proliferation or survival. Cancer can develop when certain cell signaling activity becomes abnormal, or dysregulated. Since genetic mutations are often only weakly correlated to the dysregulated signaling activity driving a patient’s cancer, a molecular diagnostic is prone to providing an incomplete diagnosis. CELsignia tests overcome this limitation by measuring dynamic cell signaling activity in a patient’s living tumor cells. When a CELsignia test detects abnormal signaling activity, a more accurate diagnosis of the patient’s cancer driver is obtained. Second, molecular diagnostics can only estimate the probability of a patient’s potential drug response based on a statistical analysis of the drug’s clinical trial results. Instead of this indirect estimate of drug response, CELsignia tests directly measure the effectiveness of a targeted therapy in a patient’s living tumor cells. This enables physicians to confirm that the therapeutic matching the patient’s cancer driver is functional in the patient’s tumor cells before prescribing it, which significantly increases the likelihood of a positive clinical outcome.
 
Our first analytically validated and commercially ready test using our CELsignia platform, the CELsignia HER2 Pathway Activity Test for breast cancer, diagnoses two new sub-types of HER2-negative breast cancer that traditional molecular diagnostics cannot detect. Our internal studies show that approximately 15-20% of HER2-negative breast cancer patients have abnormal HER2 signaling activity similar to levels found in HER2-positive breast cancer cells. As a result, these HER2-negative patients have undiagnosed HER2-driven breast cancer and would be likely to respond to the same anti-HER2 targeted therapies only HER2-positive patients receive today. We have three interventional clinical trials underway to evaluate the efficacy of HER2 targeted therapies in breast cancer patients selected with our CELsignia HER2 Pathway Activity Test.
 
Our second CELsignia test for breast cancer evaluates independent c-Met signaling activity and its involvement with HER family signaling in HER2-negative breast cancer tumor cells. Our internal studies show that approximately 20%-25% of HER2-negative breast cancer patients have abnormal c-Met signaling activity that is co-activated with abnormal HER family signaling. These studies suggest that this sub-group of HER2-negative breast cancer patients may best respond to treatment with a combination of HER family and c-Met inhibitors.
 
Our third CELsignia test for breast cancer evaluates PI3K signaling in HER2-negative breast cancer tumor cells. Our internal studies demonstrate how measurement of PI3K-involved signaling may provide a more sensitive and specific method of identifying patients most likely to benefit from PI3K inhibitors than current genetic tests that measure PI3K mutations.
 
We intend to combine these three tests to create the CELsignia Multi-Pathway Activity Test, or CELsignia MP Test. With this next generation CELsignia test, we plan to provide an analysis of EGFR/HER1, HER2, HER3, c-MET, and PI3K-node involved signaling activity for each patient tumor specimen received.
 
We completed development of our first CELsignia test for ovarian cancer in 2020. This test identifies a new sub-group of ovarian cancer patients with tumors that have abnormal c-Met and HER2 signaling activity. These findings suggest that a significant sub-group of ovarian cancer patients may respond to treatment with a combination of ErbB and c-Met inhibitors. Nearly 15,000 women a year die from ovarian cancer, a disease that has less than a 50% five-year survival rate and a limited range of targeted therapy options. There is thus a significant unmet need for additional therapeutic options for ovarian cancer patients. As a companion diagnostic, our CELsignia test for ovarian cancer will be intended to help pharmaceutical companies obtain new drug indications and expand treatment options for this challenging tumor type. We initiated discussions with pharmaceutical companies about collaborating on clinical trials in late 2020.
 
We also made significant progress in 2020 developing a new CELsignia test intended to diagnose cancers driven by dysregulated RAS signaling. Dysregulation of RAS signaling, which includes the RAF/MEK/ERK and PI3K/AKT/mTOR pathways, is estimated to drive 30%-40% of all cancers. Pharmaceutical companies have developed numerous drugs that target RAS-involved pathways. However, the number of interactions amongst RAS-regulated pathways has made it extremely difficult to use molecular tests to identify patients with dysregulated RAS signaling tumors. The challenge of diagnosing a cancer driven by a dysregulated RAS signaling network is magnified because two or more different pathways are typically involved. Recent research has also found that RAS mutations play a much less important role in dysregulated RAS signaling than previously thought. Our CELsignia platform is uniquely suited to untangle the complexity of dysregulated RAS signaling tumors and identify the targeted therapy combination capable of treating it.

Once development of the new RAS test is completed, we intend to add it to our current CELsignia Multi-Pathway Activity test for breast and ovarian cancer. This next generation CELsignia test would provide an analysis of EGFR/HER1, HER2, HER3, c-MET, PI3K, and RAS-involved signaling activity for each patient tumor specimen received. Our current CELsignia test has the potential to diagnose oncogenic signaling activity undetectable by molecular tests in up to one in three HER2-negative breast cancer patients. If our efforts to develop a RAS dynamic signaling test are successful, the percentage of cancer patients who could benefit from a CELsignia test would further increase.
 
In addition to our CELsignia tests for HER2-negative breast cancer and ovarian cancer, we expect to develop CELsignia tests to diagnose eight new potential cancer sub-types we have discovered in lung, ovarian, kidney, and bladder cancers. Approved or investigational drugs are currently available to treat these new potential cancer sub-types. We expect to launch these additional tests on a staggered basis over the next few years while continuing our research to identify additional new cancer sub-types. Our overall commercialization strategy is to develop diagnostics that expand the patient population eligible for targeted therapies. We have four collaborations underway that rely on the CELsignia test for breast cancer to select breast cancer patients for treatment with HER2 or a combination of pan-HER and c-Met targeted therapies. For the first one of these collaborations, we are fielding a prospective clinical trial with Genentech and NSABP (FACT-1) to evaluate the efficacy of Genentech’s HER2 targeted therapies in patients with abnormal HER2 signaling. For the second of these collaborations, we are fielding a prospective clinical trial with Puma and West Cancer Center (FACT-2) to evaluate the efficacy and safety of Puma’s drug, Nerlynx, and chemotherapy, in breast cancer patients selected with our CELsignia test. For our third collaboration, we are fielding a prospective open-label Phase II clinical trial with Puma Massachusetts General Hospital, the UCLA Jonsson Comprehensive Cancer Center and the Vanderbilt-Ingram Cancer Center to evaluate the efficacy of Puma’s drug, Nerlynx, and Faslodex, an AstraZeneca drug, in previously treated metastatic HR-positive, HER2-negative breast cancer patients selected with our CELsignia HER2 Pathway Activity Test. For our fourth collaboration, we are fielding a prospective open-label Phase II clinical trial with Pfizer Inc. and Sarah Cannon Research Institute to evaluate the efficacy of two Pfizer targeted therapies, Vizimpro, a pan-HER inhibitor, and Xalkori, a c-Met inhibitor, in previously treated metastatic HER2-negative breast cancer patients selected with our CELsignia Multi-Pathway Activity Test.
 
An additional collaboration to evaluate tissue samples from a Phase II study evaluating Puma’s pan-HER inhibitor, Nerlynx, Genentech’s HER2 antibody, Herceptin, and Bristol-Myers Squibb’s EGFR inhibitor, Erbitux, in metastatic colorectal cancer patients is expected to be completed in late 2022. Unlike the four clinical trial collaborations, our CELsignia test will be used solely to evaluate tissue samples after they have been enrolled in this trial. We will not receive payment for the testing we perform. We expect our CELsignia test will provide critical insight after the trial is completed about the patient characteristics most correlative to drug response.
 
In conjunction with the development of our CELsignia tests, we will seek collaborations with pharmaceutical companies to field clinical trials to advance the clinical development of their targeted therapies with the eventual goal of obtaining U.S. Food and Drug Administration (“FDA”) approval of a new drug indication. Collaborations are expected to involve initially Phase I or Phase II interventional clinical trials to evaluate the efficacy of our collaboration partners’ targeted therapies patients selected with one of our CELsignia tests. We are currently evaluating, or expect to evaluate, a variety of targeted therapies in combination with other targeted therapies, hormonal therapies, or chemotherapies, including: i) pan-HER and c-Met inhibitors; ii) pan-HER inhibitors and endocrine therapy; iii) pan-HER inhibitors and chemotherapies; and iv) PI3K inhibitors and endocrine therapy. The FDA has approved three c-Met inhibitors, six HER-family inhibitors, and four PI3K inhibitors for cancer treatment. Additional c-Met, HER-family, and PI3K inhibitors are being evaluated in on-going clinical trials.
 
While molecular tests identify increasing numbers of genetic variants in tumor tissue, determining the dysfunction driving most patient’s cancer using molecular tests remains elusive. Less than 20% of Americans who died of cancer in 2018 were eligible for a molecular targeted therapy because they lacked what are currently considered actionable genetic or proteomic mutations. This reflects the limitations of using static measurements of proteins or genetic mutations in cell fragments to characterize the dynamic and complex cell signaling activity that may be driving a patient’s cancer.
 
Directly measuring dynamic cell signaling activity is an alternative diagnostic approach to identify the cancer driver in patient tumors lacking actionable genomic or proteomic mutations. This approach requires the use of living patient tumor cells as well as technology to quantify signaling activity levels. Efforts to obtain patient tumor cells have previously been limited by the lack of reliable methods to extract and culture cancer cells from patient tumors. Lack of access to living patient tumor cells, in turn, hampered development of technology to analyze dynamic signaling activity.
 
Our CELsignia platform addresses the need for better cancer diagnostic tests using two complementary technologies that represent a significant departure from molecular-based analyses. Unlike molecular tests that use cell fragments and can only measure the static composition of a cell, our CELsignia platform measures real-time signaling activity in a patient’s live tumor cells. This enables us to (1) identify the cellular signaling dysfunction driving a patient’s cancer; and (2) identify the targeted therapy that matches the dysfunction in the patient’s cells. Our CELsignia tests are performed in our laboratory in Minneapolis, Minnesota that is certified under the Clinical Laboratory Improvement Amendments of 1988, or CLIA, and accredited by the College of American Pathologies, or CAP.
 
Our platform, comprised of our internally developed cell microenvironment and cell signaling quantification technologies, allows for more accurate diagnoses and the discovery of new cancer sub-types. We believe our CELsignia platform will fundamentally change the standard-of-care many cancer patients receive. Patients with the newly identified cancer sub-types we have discovered have oncogenic pathways that are signaling abnormally, and, we believe, may respond positively to a matching targeted therapy. By identifying patients with a new cancer sub-type, each CELsignia test will create, in effect, a proprietary patient population that molecular diagnostics cannot identify.

Our initial commercial strategy is to partner with pharmaceutical companies to provide companion diagnostics for the pharmaceutical partners’ existing or investigational targeted therapies. We expect such partnerships to involve collaboration on clinical trials, regulatory submissions, and commercialization activities. We will initiate activities to pursue partnerships as our CELsignia tests become commercially ready and can be matched with a potential partner’s targeted therapies. Our commercial-related efforts to date have focused on seeking partnerships for our CELsignia tests, the first of which became commercially ready as a laboratory developed test (“LDT”) in 2016. We expect to seek pharmaceutical partnerships for a variety of different targeted therapies in other solid tumor types as we are conducting our initial clinical trials with Genentech’s, Pfizer’s, and Puma’s targeted therapies.
 
We believe our CELsignia tests will expand the matching drug’s market size because they can facilitate approval of new drug indications that a pharmaceutical company would not otherwise be able to obtain. We expect that successful pharmaceutical company partnerships will generate significant revenue from the sale of tests to identify patients eligible for clinical trials, from milestone payments, and, potentially, from royalties on the incremental drug revenues our tests enable. A key requirement for success of these partnerships will be clinical trial results that demonstrate the advantages of using a CELsignia test as a companion diagnostic. Once a new drug indication is received that requires use of the CELsignia test to identify eligible patients, we will offer our tests directly to treating physicians and coordinate go-to-market strategies with our partner. This coordination of commercialization strategies will allow us to significantly leverage the sales, marketing and reimbursement resources of our pharmaceutical partner, unlike traditional molecular diagnostic companies.
 
We have not generated any revenue from sales to date, and we continue to incur significant research and development and other expenses related to our ongoing operations. As a result, we are not and have never been profitable and have incurred losses in each period since we began operations in 2012. For the years ended December 31, 2020 and 2019, we reported a net loss of approximately $9.5 million and $7.4 million, respectively. As of December 31, 2020, we had a combined accumulated deficit of approximately $12.6 million under Celcuity LLC and $26.3 million under Celcuity Inc. As of December 31, 2020, we had cash and cash equivalents of approximately $11.6 million.
 
Impact of COVID-19
 
A novel strain of coronavirus (COVID-19) was first identified in Wuhan, China in December 2019, and subsequently declared a pandemic by the World Health Organization. The impact of the COVID-19 pandemic on our business is discussed in further detail below:
 
Health and Safety. To help protect the health and safety of our employees, suppliers and collaborators, we took proactive, aggressive action from the earliest signs of the outbreak. We enacted rigorous safety measures in our laboratory and administrative offices, including implementing social distancing protocols, allowing working from home for those employees that do not need to be physically present in a lab to perform their work, suspending travel, implementing temperature checks at the entrances to our facilities, extensively and frequently disinfecting our workspaces and providing masks to those employees who must be physically present. We expect to continue with these measures until the COVID-19 pandemic is contained and we may take further actions as government authorities require or recommend or as we determine to be in the best interests of our employees, suppliers, and collaborators.
 
Clinical Trials and Collaborations. As a result of the COVID-19 pandemic, governmental authorities have implemented and are continuing to implement numerous and constantly evolving measures to try to contain the virus, such as travel bans and restrictions, limits on gatherings, quarantines, shelter-in-place orders, and business shutdowns. As we continue to advance our clinical trial collaborations, we are in close contact with our current clinical sponsors, and principal investigators, as well as prospective pharmaceutical company and clinical collaborators, to assess the impact of COVID-19 on our trial enrollment timelines and collaboration discussions. In light of the COVID-19 pandemic, the focus of healthcare providers and hospitals on fighting the virus, and consistent with the FDA’s updated industry guidance for conducting clinical trials issued on March 18, 2020, we are experiencing delays in the enrollment of patients in our ongoing clinical trials. We now expect interim results from the FACT-1 and FACT-2 trials to be delayed until the fourth quarter of 2021 or first quarter of 2022 and final results approximately nine months later. As the impact of COVID-19 on our industry becomes clearer, we may need to reassess the timing of our anticipated clinical milestones. Prospective clinical trial collaborations with pharmaceutical companies and sponsors may also be delayed but the impact on the timing of finalizing agreements is not yet known.
 
 
 
 
S-4
 
 
 

Research and Development. While our facility currently remains operational, the evolving measures to try to contain the virus have impacted and may further impact our workforce and operations, as well as those of our vendors and suppliers. Our laboratory remains operational as of this date, but, in response to the COVID-19 pandemic, we have implemented protective policies that reduce the number of research and development staff operating in our laboratory at any one time. While governmental measures may be modified or extended, we expect that our research and development and clinical laboratory will remain operational. However, in light of the focus of healthcare providers and hospitals on fighting the virus, several of the clinical sites that provide us tumor tissue for research have halted this service, reducing the number of new tumor tissue specimens we would typically expect to receive. These various constraints may slow or diminish our research and development activities. In addition, cancer research-related industry meetings, such as the American Association for Cancer Research (AACR), were delayed for several months. Our submissions to present research results at these meetings were accepted, but the release of the results was postponed in conjunction with the delayed meeting schedules.
 
Liquidity. Although there is uncertainty related to the anticipated impact of the recent COVID-19 outbreak on our future results, we believe our existing balance of cash and cash equivalents will be sufficient to meet our cash needs arising in the ordinary course of business for at least the next twelve months. We continue to monitor the rapidly evolving situation and guidance from federal, state and local public health authorities and may take additional actions based on their recommendations. In these circumstances, there may be developments outside our control requiring us to adjust our operating plan.

Implications of Being an Emerging Growth Company
 
We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, and, for as long as we continue to be an “emerging growth company,” we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to “emerging growth companies,” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We could be an “emerging growth company” for up to five years, or until the earliest of (i) the last day of the first fiscal year in which our annual gross revenues exceed $1.07 billion, (ii) the date that we become a “large accelerated filer” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended, which would occur if the market value of our common shares that is held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter, or (iii) the date on which we have issued more than $1 billion in non-convertible debt during the preceding three-year period.

Risks Relating to This Offering
 
We have broad discretion in the use of the proceeds of this offering and may apply the proceeds in ways with which you do not agree.
 
Our net proceeds from this offering will be used primarily for working capital and general corporate purposes, which may include capital expenditures, research and development expenditures, clinical trial expenditures, expansion of business development activities, and other general corporate purposes. We may also use a portion of the proceeds for the potential acquisition of businesses, technologies and products, although we have no current binding understandings, commitments or agreements to do so. Our management will have broad discretion over the use and investment of these net proceeds, and, accordingly, you will have to rely upon the judgment of our management with respect to our use of these net proceeds, with only limited information concerning management’s specific intentions. You will not have the opportunity, as part of your investment decision, to assess whether we used the net proceeds from this offering appropriately. We may place the net proceeds in investments that do not produce income or that lose value, which may cause our stock price to decline.
 
Future sales and issuances of our common stock could cause our stock price to fall.
 
Sales of a substantial number of shares of our common stock by our existing stockholders in the public market, or the perception that these sales might occur, could depress the market price of our common stock and could impair our ability to raise additional capital through the issuance of additional equity securities. We are unable to predict the effect that such sales may have on the prevailing market price of our common stock.
 
To the extent we raise additional capital by issuing additional shares of our common stock, or securities convertible into or exchangeable or exercisable for common stock, our existing stockholders may experience substantial dilution. In addition, future investors could gain rights superior to existing stockholders, such as liquidation and other preferences. We have stock options and warrants outstanding to purchase shares of our capital stock. Our stockholders may incur dilution upon exercise of any outstanding stock options and warrants.
 
You will experience immediate and substantial dilution.
 
The public offering price per share in this offering exceeds the net tangible book value per share of our common stock outstanding prior to this offering. Based on the public offering price, you will experience immediate dilution of $11.16 per share, representing the difference between our as adjusted net tangible book value per share as of December 31, 2020 after giving effect to this offering and the public offering price. The exercise of outstanding stock options and warrants may result in further dilution of your investment. See the section entitled “Dilution” below for a more detailed illustration of the dilution you would incur if you participate in this offering.
 
We may need additional capital and any additional capital we seek may not be available in the amount or at the time we need it.
 
We believe that the proceeds from this offering, together with our existing cash and cash equivalents, will be sufficient to fund our operations for at least the next 12 months. However, if we are not able to increase our revenues, generate positive cash flow or operate in a profitable manner, we may need to raise funds in the future to execute our business plan.
 
We may seek to raise additional capital to expand our business, pursue strategic investments, and take advantage of financing or other opportunities that we believe to be in the best interests of the Company and our stockholders. Additional capital may be raised through the sale of common or preferred equity or convertible debt securities, entry into debt facilities or other third-party funding arrangements. The sale of equity and convertible debt securities may result in dilution to our stockholders and those securities may have rights senior to those of our common shares. Agreements entered into in connection with such capital raising activities could contain covenants that would restrict our operations or require us to relinquish certain rights. Additional capital may not be available on reasonable terms, or at all. If we cannot timely raise any needed funds, we may be forced to reduce our operating expenses, which could adversely affect our ability to implement our long-term strategic roadmap and grow our business.
 
Our expected financing needs are based upon management estimates as to future revenue and expense. Our business plan and financing needs are subject to change based upon, among other factors, our ability to increase revenues, our ability to achieve cash flow, and our ability to manage expenses. If our estimates of our financing needs change, we may need additional capital more quickly than we expect or we may need a greater amount of capital.

Our stock price is volatile and subject to significant fluctuations and our common stock is thinly traded.
 
The market price of our common stock could be subject to significant fluctuations. Market prices for securities of early-stage pharmaceutical, medical device, biotechnology and other life sciences companies have historically been particularly volatile. Our common stock is thinly-traded, which also impacts the market price. Our common stock traded as low as $4.03 and as high as $16.19 per share during the 12-month period ended January 31, 2021. Factors that may cause the market price of our common stock to fluctuate include, but are not limited to:
 
announcements of technological or medical innovations for the treatment of the cancers treated by our products;
quarterly variations in our or our competitors’ results of operations;
failure to meet our product development, clinical, international expansion, regulatory, or other milestones;
accusations that we have violated a law or regulation;
significant litigation;
sales of large blocks of our common stock, including sales by our executive officers, directors and significant stockholders;
changes in accounting principles;
actual or anticipated changes in healthcare policy and reimbursement levels;
developments relating to our competitors and markets; and
general market conditions and other factors, including factors unrelated to our operating performance or the operating performance of our competitors.
 
Moreover, the stock markets in general have experienced substantial volatility that has often been unrelated to the operating performance of individual companies, and the stock markets have experienced, and will likely continue to experience, substantial volatility as a result of the ongoing COVID-19 pandemic. These broad market fluctuations may also adversely affect the trading price of our common stock.
 
We do not expect to pay cash dividends for the foreseeable future, and accordingly, stockholders must rely on stock appreciation for any return on their investment in the company.
 
We have never declared or paid any cash dividends on our common stock and currently we anticipate that we will retain our earnings, if any, for future growth and therefore do not anticipate that we will pay cash dividends for the foreseeable future. As a result, appreciation of the price of our common stock is the only potential source of return to stockholders. Investors seeking cash dividends should not invest in our common stock.
 
If securities or industry analysts issue an adverse opinion regarding our stock, our stock price and trading volume could decline. 
 
The trading market for our common stock is influenced by the research and reports that securities or industry analysts may publish about us, our business, our market or our competitors. If any of the analysts who may cover us adversely change its recommendation regarding our common stock, or provide more favorable relative recommendations about our competitors, the trading price of our common stock could decline. If any analyst who may cover us were to cease coverage of our Company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the trading price of our common stock or trading volume to decline.

USE OF PROCEEDS
 
We estimate that the net proceeds to us from this offering will be approximately $22.4 million, or approximately $25.8 million if the underwriter exercises its over-allotment option in full, after deducting the underwriting discount and estimated offering expenses payable by us.
 
We intend to use the net proceeds from this offering for working capital and general corporate purposes. General corporate purposes may include capital expenditures, research and development expenditures, clinical trial expenditures, expansion of business development activities and other general corporate purposes. We may also use a portion of the proceeds for the potential acquisition of businesses, technologies and products, although we have no current binding understandings, commitments or agreements to do so.
 
As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds to us from this offering. Accordingly, we will retain broad discretion over the use of these proceeds. Pending these uses, we intend to invest the net proceeds in investment-grade, interest-bearing securities.
 
 
 
 
 
S-11
 
DILUTION
 
If you purchase our common stock in this offering, your interest will be diluted to the extent of the difference between the public offering price per share and the net tangible book value per share of our common stock after this offering. We calculate net tangible book value per share by dividing our net tangible assets (tangible assets less total liabilities) by the number of shares of our common stock issued and outstanding as of December 31, 2020.
 
Our net tangible book value at December 31, 2020 was $11,702,270, or $1.14 per share. After giving effect to this offering, and after deducting the underwriting discount and estimated offering expenses payable by us, our as adjusted net tangible book value as of December 31, 2020, would have been $34,090,010, or $2.84 per share of common stock. This represents an immediate increase in the net tangible book value of $1.70 per share to our existing stockholders and an immediate dilution in net tangible book value of $11.16 per share to new investors. The following table illustrates this per share dilution:
 
Public offering price per share
 
 
 
 $14.00 
Net tangible book value per share as of December 31, 2020
 $1.14 
    
Increase in net tangible book value per share attributable to this offering
 $1.70 
    
As adjusted net tangible book value per share as of December 31, 2020, after giving effect to this offering
    
 $2.84 
Dilution per share to new investors purchasing shares in this offering
    
 $11.16 
 
The information above assumes that the underwriter does not exercise its over-allotment option in full. If the underwriter exercises its over-allotment option to purchase 257,100 additional shares in full, the as adjusted net tangible book value as of December 31, 2020 would be $3.05 per share, representing an immediate increase in the net tangible book value of $1.91 per share to our existing stockholders and an immediate dilution in net tangible book value of $10.95 per share to new investors.
 
The number of shares of common stock outstanding after this offering as reflected in the table above is based on the actual number of shares outstanding as of December 31, 2020, which was 10,299,822 and does not include, as of that date:
 
849,949 shares of our common stock issuable upon exercise of outstanding options at a weighted average price of $9.33 per share;
 
353,585 shares of our common stock issuable upon exercise of outstanding warrants with a weighted-average exercise price of $9.42 per share; and
 
311,133 shares of our common stock reserved for issuance under our Amended and Restated 2017 Stock Incentive Plan and our 2017 Employee Stock Purchase Plan.
 
To the extent that options or warrants as of December 31, 2020 have been or are exercised, or other shares are issued, investors purchasing shares in this offering could experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

Craig-Hallum Capital Group LLC is acting as the sole managing underwriter of this offering. The underwriter named below has agreed to buy, subject to the terms of the underwriting agreement, the number of shares of common stock listed opposite its name below. The underwriter is committed to purchase and pay for all of the shares if any are purchased, other than those shares covered by the over-allotment option described below.

The underwriter has advised us that it proposes to offer the shares of common stock to the public at a price of $14.00 per share. The underwriter proposes to offer the shares of common stock to certain dealers at the same price less a concession of not more than $0.504 per share. After the offering, these figures may be changed by the underwriter.
 
The shares sold in this offering are expected to be ready for delivery on or about February 26, 2021, against payment in immediately available funds. The underwriter may reject all or part of any order.
 
We have granted to the underwriter an option to purchase up to an additional 257,100 shares of common stock from us at the same price to the public, and with the same underwriting discount, as set forth in the table below. The underwriter may exercise this option any time during the 30-day period after the date of this prospectus supplement, but only to cover over-allotments, if any. To the extent the underwriter exercises the option, the underwriter will become obligated, subject to certain conditions, to purchase the shares for which it exercises the option.
 
The table below summarizes the underwriting discounts that we will pay to the underwriter. These amounts are shown assuming both no exercise and full exercise of the over-allotment option. In addition to the underwriting discount, we have agreed to pay up to $112,500 of the fees and expenses of the underwriter, which may include the fees and expenses of counsel to the underwriter. The fees and expenses of the underwriter that we have agreed to reimburse are not included in the underwriting discounts set forth in the table below. The underwriting discount and reimbursable expenses the underwriter will receive were determined through arms length negotiations between us and the underwriter.

We estimate that the total expenses of this offering, excluding the underwriting discount, will be approximately $168,500. This includes $112,500 of the fees and expenses of the underwriter. These expenses are payable by us.
 
We also have agreed to indemnify the underwriter against certain liabilities, including civil liabilities under the Securities Act, or to contribute to payments that the underwriter may be required to make in respect of those liabilities.
 
No Sales of Similar Securities
 
We and each of our directors and executive officers have agreed not to offer, sell, agree to sell, directly or indirectly, or otherwise dispose of any shares of common stock or any securities convertible into or exchangeable for shares of common stock without the prior written consent of the underwriter for a period of 90 days after the date of this prospectus supplement. Notwithstanding the foregoing, we will be permitted to issue common stock, options or convertible securities to a strategic investor in connection with a license, joint venture, collaboration or similar agreement. These lock-up agreements provide other limited exceptions, and their restrictions may be waived at any time by the underwriter.

Price Stabilization, Short Positions and Penalty Bids
 
To facilitate this offering, the underwriter may engage in transactions that stabilize, maintain or otherwise affect the price of our common stock during and after the offering. Specifically, the underwriter may over-allot or otherwise create a short position in our common stock for its own account by selling more shares of common stock than we have sold to the underwriter. The underwriter may close out any short position by either exercising its option to purchase additional shares or purchasing shares in the open market.
 
In addition, the underwriter may stabilize or maintain the price of our common stock by bidding for or purchasing shares in the open market and may impose penalty bids. If penalty bids are imposed, selling concessions allowed to broker-dealers participating in this offering are reclaimed if shares previously distributed in this offering are repurchased, whether in connection with stabilization transactions or otherwise. The effect of these transactions may be to stabilize or maintain the market price of our common stock at a level above that which might otherwise prevail in the open market. The imposition of a penalty bid may also affect the price of our common stock to the extent that it discourages resales of our common stock. The magnitude or effect of any stabilization or other transactions is uncertain. These transactions may be effected on the Nasdaq Capital Market or otherwise and, if commenced, may be discontinued at any time.
 
In connection with this offering, the underwriter and selling group members may also engage in passive market making transactions in our common stock on the Nasdaq Capital Market. Passive market making consists of displaying bids on the Nasdaq Capital Market limited by the prices of independent market makers and effecting purchases limited by those prices in response to order flow. Rule 103 of Regulation M promulgated by the SEC limits the amount of net purchases that each passive market maker may make and the displayed size of each bid. Passive market making may stabilize the market price of our common stock at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.
 
Neither we nor the underwriter make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor the underwriter make any representation that the underwriter will engage in these transactions or that any transaction, if commenced, will not be discontinued without notice.

Our certificate of incorporation, as amended, and bylaws contain provisions that could have the effect of discouraging potential acquisition proposals or tender offers or delaying or preventing a change of control of our Company. A summary of these provisions is as follows:
 
Board vacancies. The bylaws authorize only the Board to fill vacant directorships, including newly created seats. In addition, the number of directors constituting the Board will be permitted to be set only by a resolution adopted by the Board. These provisions would prevent a stockholder from increasing the size of the Board and then gaining control of the Board by filling the resulting vacancies with its own nominees. This makes it more difficult to change the composition of the Board but promotes continuity of management.
 
Advance notice requirements for stockholder proposals and director nominations.  Our bylaws provide advance notice procedures for stockholders seeking to bring business before an annual meeting of stockholders or to nominate candidates for election as directors at an annual meeting of stockholders. The bylaws also specify certain requirements regarding the form and content of a stockholder’s notice. These provisions might preclude stockholders from bringing matters before an annual meeting of stockholders or from making nominations for directors at an annual meeting of stockholders if the proper procedures are not followed. These provisions may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of the Company.
 
No cumulative voting.   The Delaware General Corporation Law, or DGCL, provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless a corporation’s certificate of incorporation provides otherwise. Our certificate of incorporation, as amended, does not provide for cumulative voting.
 
Stockholder action; special meetings of stockholders.  Our certificate of incorporation, as amended, provides that our stockholders may not take action by written consent, but may only take action at annual or special meetings of our stockholders. As a result, a holder controlling a majority of our capital stock would not be able to amend our bylaws or remove directors without holding a meeting of our stockholders called in accordance with our bylaws. Further, our bylaws provide that special meetings of our stockholders may be called only by a majority of our board of directors, the chairperson of our board of directors, or our Chief Executive Officer, thus prohibiting a stockholder from calling a special meeting. These provisions might delay the ability of our stockholders to force consideration of a proposal or for stockholders controlling a majority of our capital stock to take any action, including the removal of directors.
 
Issuance of undesignated preferred stock.  We have 2,500,000 shares of undesignated preferred stock. Our board of directors has the authority, without further action by the stockholders, to issue this preferred stock with rights and preferences, including voting rights, designated from time to time by our board of directors. The existence of authorized but unissued shares of preferred stock would enable our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or other means.
 
Amendment of charter and bylaw provisions The affirmative vote of stockholders representing at least two-thirds of the voting power of all then-outstanding capital stock is required to amend, alter or repeal certain provisions of our certificate of incorporation, as amended, including the provision noted above regarding stockholders not being able to act by written consent. A majority of our board of directors has authority to adopt, amend or repeal provisions of our bylaws. Stockholders also have the authority to adopt, amend or repeal provisions of our bylaws, but only with the affirmative vote of stockholders representing at least two-thirds of the voting power of all then-outstanding capital stock.
 
We are subject to the provisions of Section 203 of the DGCL, an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. For purposes of Section 203, a “business combination” includes a merger, asset sale or other transaction resulting in a financial benefit to the interested stockholder, and an “interested stockholder” is a person who owns 15% or more of the voting stock of a corporation, or any affiliate or associate of a corporation who, within three years prior, did own 15% or more of the voting stock of that corporation.

Indemnification of Directors and Officers
 
Section 102(b)(7) of the DGCL provides that a Delaware corporation, in its certificate of incorporation, may limit the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duties as a director, except for liability for any:
 
transaction from which the director derived an improper personal benefit;
act or omission not in good faith or that involved intentional misconduct or a knowing violation of law;
unlawful payment of dividends or redemption of shares; or
breach of the director’s duty of loyalty to the corporation or its stockholders.
 
Section 145(a) of the DGCL provides, in general, that a Delaware corporation may indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) because that person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, so long as the person acted in good faith and in a manner he or she reasonably believed was in or not opposed to the corporation’s best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.
 
Section 145(b) of the DGCL provides, in general, that a Delaware corporation may indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action or suit by or in the right of the corporation to obtain a judgment in its favor because the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise. The indemnity may include expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action, so long as the person acted in good faith and in a manner the person reasonably believed was in or not opposed to the corporation’s best interests, except that no indemnification shall be permitted without judicial approval if a court has determined that the person is to be liable to the corporation with respect to such claim. Section 145(c) of the DGCL provides that, if a present or former director or officer has been successful in defense of any action referred to in Sections 145(a) and (b) of the DGCL, the corporation must indemnify such officer or director against the expenses (including attorneys’ fees) he or she actually and reasonably incurred in connection with such action.
 
Section 145(g) of the DGCL provides, in general, that a corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise against any liability asserted against and incurred by such person, in any such capacity, or arising out of his or her status as such, whether or not the corporation could indemnify the person against such liability under Section 145 of the DGCL.
 
Our certificate of incorporation, as amended, and our bylaws provide for the limitation of liability and indemnification of our directors and officers to the fullest extent permitted under the DGCL.
 
We have also entered into separate indemnification agreements with our directors and officers in addition to the indemnification provided for in our certificate of incorporation, as amended, and our bylaws. These indemnification agreements provide, among other things, that we will indemnify our directors and officers for certain expenses, including damages, judgments, fines, penalties, settlements and costs and attorneys’ fees and disbursements, incurred by a director or officer in any claim, action or proceeding arising in his or her capacity as a director or officer of the Company or in connection with service at our request for another corporation or entity. The indemnification agreements also provide for procedures that will apply in the event that a director or officer makes a claim for indemnification.
 
We also maintain a directors’ and officers’ insurance policy pursuant to which our directors and officers are insured against liability for actions taken in their capacities as directors and officers.
 
SEC Position on Indemnification for Securities Act Liabilities
 
Insofar as indemnification for liabilities arising under the Securities Act may be permitted for directors, officers or persons controlling our Company, we understand that it is the SEC’s opinion that such indemnification is against public policy as expressed in the Securities Act and therefore is unenforceable.

 OUR COMPANY
 
We are a cellular analysis company that is discovering new cancer sub-types and commercializing diagnostic tests designed to significantly improve the clinical outcomes of cancer patients treated with targeted therapies. Our proprietary CELx diagnostic platform is the only commercially ready technology we are aware of that uses a patient’s living tumor cells to identify the specific abnormal cellular process driving a patient’s cancer and the targeted therapy that best treats it. We believe our CELx platform provides two important improvements over traditional molecular diagnostics. First, molecular diagnostics can only provide a snapshot of the genetic mutations present in a patient’s tumor because they analyze dead cells. Using dead cells prevents molecular diagnostics from analyzing in real-time the dynamic cellular activities, known as cell signaling, that regulate cell proliferation or survival. Cancer can develop when certain cell signaling activity becomes abnormal. Since genetic mutations are often only weakly correlated to the cell signaling activity driving a patient’s cancer, a molecular diagnostic is prone to providing an incomplete diagnosis. CELx tests overcome this limitation by measuring real-time cell signaling activity in a patient’s living tumor cells. When a CELx test detects abnormal signaling activity, a more accurate diagnosis of the patient’s cancer driver is obtained. Second, molecular diagnostics can only estimate the probability of a patient’s potential drug response based on a statistical analysis of the drug’s clinical trial results. Instead of this indirect estimate of drug response, CELx tests directly measure the effectiveness of a targeted therapy in a patient’s living tumor cells. This enables physicians to confirm that the therapeutic matching the patient’s cancer driver is functional in the patient’s tumor cells before prescribing it, which significantly increases the likelihood of a positive clinical outcome.
 
Our first analytically validated and commercially ready test using our CELx platform, the CELx HSF Test, diagnoses two new sub-types of HER2-negative breast cancer that traditional molecular diagnostics cannot detect. Our internal studies show that approximately 20% of HER2-negative breast cancer patients have abnormal HER2 signaling activity similar to levels found in HER2+ breast cancer cells. As a result, these HER2-negative patients have undiagnosed HER2-driven breast cancer and would be likely to respond to the same anti-HER2 targeted therapies only HER2+ patients receive today. Our CELx HSF Test is targeting HER2-negative breast cancer patients receiving drug treatment.
 
We completed development of our second CELx test for breast cancer during the first quarter of 2018. This new test evaluates independent c-Met signaling activity and its involvement with HER family signaling in HER2-negative breast cancer tumor cells. We intend to combine this c-Met signaling function test with our current HER2 signaling function test to create the CELx Multi-Pathway (MP) Test. Our internal studies show that approximately 15%-20% of HER2-negative breast cancer patients have abnormal c-Met signaling activity that is co-activated with abnormal HER1 signaling. These studies suggest that this sub-group of HER2-negative breast cancer patients may best respond to treatment with a combination of HER family and c-Met inhibitors. With this next generation CELx test, we plan to provide an analysis of HER1, HER2, HER3, and c-MET signaling activity with a single patient tumor specimen.
 
 Our overall strategy is to develop diagnostics that identify new cancer sub-types and to seek collaborations with pharmaceutical companies, which can vary in scope. For our first collaboration, we are fielding a prospective clinical trial with Genentech and the NSABP to evaluate the efficacy of Genentech’s HER2 targeted therapies in patients with these newly identified cancer sub-types. For our second collaboration, Celcuity was selected by NSABP and Puma Biotechnology to evaluate tissue samples from a Phase II study evaluating Puma Biotechnology’s pan-HER inhibitor, Nerlynx, Genentech’s HER2 antibody, Herceptin, and Bristol-Myers Squibb’s drug, EGFR inhibitor, Erbitux, in metastatic colorectal cancer patients. Unlike the trial with NSABP and Genentech, Celcuity’s test will be used solely to evaluate tissue samples after they have been enrolled in this trial. Celcuity will not receive payment for the testing it performs. No formal agreement, other than what is described in the clinical trial protocol, has been entered into governing the terms of this relationship. We expect our CELx test will provide critical insight after the trial is completed about the patient characteristics most correlative to drug response.
 
We are also developing CELx tests to diagnose 12 new potential cancer sub-types we have discovered in lung, colon, ovarian, kidney, bladder and hematological cancers. Approved or investigational drugs are currently available to treat these new potential cancer sub-types. We expect to launch these additional tests on a staggered basis over the next few years while continuing our research to identify additional new cancer sub-types.
 
We were organized as a Minnesota limited liability company under the name Celcuity LLC in 2011 and commenced operations in 2012. In connection with our initial public offering in September 2017, we converted to a Delaware corporation named Celcuity Inc. To date, we have not generated any revenue and have devoted substantially all of our resources to research and development.
 
Our common stock is traded on The Nasdaq Capital Market under the symbol “CELC.” On September 18, 2018, the closing price of our common stock was $29.25. As of September 18, 2018, the aggregate market value of our outstanding common stock held by non-affiliates was approximately $168,950,633, based on 10,151,334 shares of outstanding common stock, of which approximately 5,776,090 shares are held by non-affiliates, and a per share price of $29.25 based on the closing sale price of our common stock on September 18, 2018.

 RISK FACTORS
 
Investing in our securities involves risk. You should consider the risks, uncertainties and assumptions discussed under the heading “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 filed on March 15, 2018 with the Securities and Exchange Commission (“SEC”), which is incorporated herein by reference, and may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations. If any of these risks were to occur, our business, financial condition, and results of operations could be severely harmed. This could cause the trading price of our common stock to decline, and you could lose all or part of your investment.
 
In addition, any prospectus supplement applicable to each offering of our securities will contain a discussion of the risks applicable to such an investment in us. Prior to making a decision about investing in our securities, you should carefully consider the specific factors discussed under the heading “Risk Factors” in the applicable prospectus supplement, together with all of the other information contained or incorporated by reference in such prospectus supplement or appearing or incorporated by reference in this prospectus.
 
FORWARD-LOOKING STATEMENTS
 
This prospectus, any prospectus supplement and the other documents we have filed with the SEC that are incorporated herein by reference contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve risks and uncertainties, as well as assumptions that, if they never materialize or prove incorrect, could cause the results of Celcuity to differ materially from those expressed or implied by such forward-looking statements. All statements other than statements of historical fact are statements that could be deemed forward-looking statements,  including but not limited to: (i) our clinical trial plans and the estimated costs for such trials; (ii) our expectations regarding the development and launch of our CELx test; (iii) our beliefs related to the perceived advantages of our CELx tests compared to traditional molecular or other diagnostic tests; (iv) our expectations regarding the timeline of results from our clinical trials; (v) our expectations regarding partnering with pharmaceutical partners; (vi) our expectations regarding revenue from sales of CELx tests and revenue from milestone or other payment sources; (vii) our plans with respect to research and development and related expenses for the foreseeable future; (viii) our expectations regarding business development activities, including companion diagnostic related activities with pharmaceutical companies; (ix) our expectations with respect to costs and timelines to develop and validate CELx tests; (x) our expectations with respect to creating the CELx Multi-Pathway (MP) Test and the analytical capabilities of such test; (xi) our plans to expand operations; and (xii) our beliefs regarding the ability of our cash on hand to fund our research and development expenses, capital expenditures, working capital, sales and marketing expenses, and general corporate expenses, as well as for the increased costs associated with being a public company.

 USE OF PROCEEDS
 
Except as otherwise provided in the applicable prospectus supplement, we intend to use the net proceeds from the sale of the securities covered by this prospectus for general corporate purposes. General corporate purposes may include working capital, capital expenditures, research and development expenditures, clinical trial expenditures, expansion of sales, marketing and reimbursement functions and other general corporate purposes. We may also use a portion of our net proceeds to acquire or invest in complementary products, technologies or businesses, although we have no present commitments to complete any such transaction. Additional information on the use of net proceeds from the sale of securities covered by this prospectus may be set forth in any prospectus supplement relating to the specific offering.
 
The amounts and timing of our expenditures will depend on numerous factors, including the status, results and timing of the current and expected clinical trials involving our CELx tests and our current and expected nonclinical studies for additional diagnostic tests. Accordingly, our management will have broad discretion over the use of the net proceeds from the sale of any securities offered by us.
 
 PLAN OF DISTRIBUTION
 
We may sell the securities offered through this prospectus (1) to or through underwriters or dealers, (2) directly to purchasers, including our affiliates, (3) through agents, or (4) through a combination of any of these methods. The securities may be distributed at a fixed price or prices, which may be changed, market prices prevailing at the time of sale, prices related to the prevailing market prices, or negotiated prices. The prospectus supplement will include the following information:
 
 
 
the terms of the offering;
 
 
the names of any underwriters or agents;
 
 
the name or names of any managing underwriter or underwriters;
 
 
the purchase price of the securities;
 
 
the net proceeds from the sale of the securities;
 
 
any delayed delivery arrangements;
 
 
any underwriting discounts, commissions and other items constituting underwriters’ compensation;
 
 
any initial public offering price;
 
 
any discounts or concessions allowed or reallowed or paid to dealers; and
 
 
any commissions paid to agents.
 
Sale through underwriters or dealers
 
If underwriters are used in the sale, the underwriters will acquire the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements with us. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions. Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless otherwise indicated in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers. The prospectus supplement will include the names of the principal underwriters, the respective amount of securities underwritten, the nature of the obligation of the underwriters to take the securities and the nature of any material relationship between an underwriter and us.
 
If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The prospectus supplement will include the names of the dealers and the terms of the transaction.
 
Direct sales and sales through agents
 
We may sell the securities offered through this prospectus directly. In this case, no underwriters or agents would be involved. Such securities may also be sold through agents designated from time to time. The prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent by us. Unless otherwise indicated in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. The terms of any such sales will be described in the prospectus supplement.
 
Delayed delivery contracts
 
If the prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.
 
Market making, stabilization and other transactions
 
Unless the applicable prospectus supplement states otherwise, each series of securities offered by us will be a new issue and will have no established trading market, other than our common stock, which is listed on The Nasdaq Capital Market. We may elect to list any series of offered securities on an exchange. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.
 
Any underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Securities Exchange Act of 1934, as amended. Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.
 
Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.
 
Derivative transactions and hedging
 
We, the underwriters or other agents may engage in derivative transactions involving the securities. These derivatives may consist of short sale transactions and other hedging activities. The underwriters or agents may acquire a long or short position in the securities, hold or resell securities acquired and purchase options or futures on the securities and other derivative instruments with returns linked to or related to changes in the price of the securities. In order to facilitate these derivative transactions, we may enter into security lending or repurchase agreements with the underwriters or agents. The underwriters or agents may effect the derivative transactions through sales of the securities to the public, including short sales, or by lending the securities in order to facilitate short sale transactions by others. The underwriters or agents may also use the securities purchased or borrowed from us or others (or, in the case of derivatives, securities received from us in settlement of those derivatives) to directly or indirectly settle sales of the securities or close out any related open borrowings of the securities.
 
Electronic auctions
 
We may also make sales through the Internet or through other electronic means. Since we may from time to time elect to offer securities directly to the public, with or without the involvement of agents, underwriters or dealers, utilizing the Internet or other forms of electronic bidding or ordering systems for the pricing and allocation of such securities, you should pay particular attention to the description of that system we will provide in a prospectus supplement.
 
Such electronic system may allow bidders to directly participate, through electronic access to an auction site, by submitting conditional offers to buy that are subject to acceptance by us, and which may directly affect the price or other terms and conditions at which such securities are sold. These bidding or ordering systems may present to each bidder, on a so-called “real-time” basis, relevant information to assist in making a bid, such as the clearing spread at which the offering would be sold, based on the bids submitted, and whether a bidder’s individual bids would be accepted, prorated or rejected. For example, in the case of a debt security, the clearing spread could be indicated as a number of “basis points” above an index treasury note. Of course, many pricing methods can and may also be used.

Upon completion of such an electronic auction process, securities will be allocated based on prices bid, terms of bid or other factors. The final offering price at which securities would be sold and the allocation of securities among bidders would be based in whole or in part on the results of the Internet or other electronic bidding process or auction.
 
General information
 
Agents, underwriters, and dealers may be entitled, under agreements entered into with us, to indemnification by us against certain liabilities, including liabilities under the Securities Act.

Anti-Takeover Effect of Delaware Law and Certain Charter and Bylaw Provisions
 
Our certificate of incorporation, as amended, and bylaws contain provisions that could have the effect of discouraging potential acquisition proposals or tender offers or delaying or preventing a change of control of our company. A summary of these provisions is as follows:
 
 
 
Board of directors vacancies.   Our bylaws authorize only our board of directors to fill vacant directorships, including newly created seats. In addition, the number of directors constituting our board of directors will be permitted to be set only by a resolution adopted by our board of directors. These provisions would prevent a stockholder from increasing the size of our board of directors and then gaining control of our board of directors by filling the resulting vacancies with its own nominees. This makes it more difficult to change the composition of our board of directors but promotes continuity of management.
 
 
 
 
 
 
Advance notice requirements for stockholder proposals and director nominations.   Our bylaws provide advance notice procedures for stockholders seeking to bring business before our annual meeting of stockholders or to nominate candidates for election as directors at our annual meeting of stockholders. Our bylaws also specify certain requirements regarding the form and content of a stockholder’s notice. These provisions might preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders if the proper procedures are not followed. These provisions may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of the company.
 
 
8
 
 
 
 
 
No cumulative voting .  The Delaware General Corporation Law, or DGCL, provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless a corporation’s certificate of incorporation provides otherwise. Our certificate of incorporation, as amended, does not provide for cumulative voting. 
 
 
 
 
 
 
 
Stockholder action; special meetings of stockholders .  Our certificate of incorporation, as amended, provides that our stockholders may not take action by written consent, but may only take action at annual or special meetings of our stockholders. As a result, a holder controlling a majority of our capital stock would not be able to amend our bylaws or remove directors without holding a meeting of our stockholders called in accordance with our bylaws. Further, our bylaws provide that special meetings of our stockholders may be called only by a majority of our board of directors, the chairperson of our board of directors, or our Chief Executive Officer, thus prohibiting a stockholder from calling a special meeting. These provisions might delay the ability of our stockholders to force consideration of a proposal or for stockholders controlling a majority of our capital stock to take any action, including the removal of directors. 
 
 
 
Issuance of undesignated preferred stock.   We have 2,500,000 shares of undesignated preferred stock. Our board of directors will has the authority, without further action by the stockholders, to issue this preferred stock with rights and preferences, including voting rights, designated from time to time by our board of directors. The existence of authorized but unissued shares of preferred stock would enable our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or other means.
 
 
 
 
 
 
Amendment of charter and bylaw provisions  The affirmative vote of stockholders representing at least two-thirds of the voting power of all then-outstanding capital stock is required to amend, alter or repeal certain provisions of our certificate of incorporation, as amended, including the provision noted above regarding stockholders not being able to act by written consent. A majority of our board of directors has authority to adopt, amend or repeal provisions of our bylaws. Stockholders also have the authority to adopt, amend or repeal provisions of our bylaws, but only with the affirmative vote of stockholders representing at least two-thirds of the voting power of all then-outstanding capital stock.
 
We are subject to the provisions of Section 203 of the DGCL, an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. For purposes of Section 203, a “business combination” includes a merger, asset sale or other transaction resulting in a financial benefit to the interested stockholder, and an “interested stockholder” is a person who owns 15% or more of the voting stock of a corporation, or any affiliate or associate of a corporation who, within three years prior, did own 15% or more of the voting stock of that corporation.
 
Indemnification of Directors and Officers
 
Section 102(b)(7) of the DGCL provides that a Delaware corporation, in its certificate of incorporation, may limit the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duties as a director, except for liability for any:
 
 
transaction from which the director derived an improper personal benefit;
 
 
act or omission not in good faith or that involved intentional misconduct or a knowing violation of law;
 
 
unlawful payment of dividends or redemption of shares; or
 
 
breach of the director’s duty of loyalty to the corporation or its stockholders.
 
Section 145(a) of the DGCL provides, in general, that a Delaware corporation may indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) because that person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, so long as the person acted in good faith and in a manner he or she reasonably believed was in or not opposed to the corporation’s best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.
 
 
9
 
 
Section 145(b) of the DGCL provides, in general, that a Delaware corporation may indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action or suit by or in the right of the corporation to obtain a judgment in its favor because the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise. The indemnity may include expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action, so long as the person acted in good faith and in a manner the person reasonably believed was in or not opposed to the corporation’s best interests, except that no indemnification shall be permitted without judicial approval if a court has determined that the person is to be liable to the corporation with respect to such claim. Section 145(c) of the DGCL provides that, if a present or former director or officer has been successful in defense of any action referred to in Sections 145(a) and (b) of the DGCL, the corporation must indemnify such officer or director against the expenses (including attorneys’ fees) he or she actually and reasonably incurred in connection with such action.
 
Section 145(g) of the DGCL provides, in general, that a corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise against any liability asserted against and incurred by such person, in any such capacity, or arising out of his or her status as such, whether or not the corporation could indemnify the person against such liability under Section 145 of the DGCL.
 
Our certificate of incorporation, as amended, and our bylaws provide for the limitation of liability and indemnification of our directors and officers to the fullest extent permitted under the DGCL.
 
We have also entered into separate indemnification agreements with our directors and officers in addition to the indemnification provided for in our certificate of incorporation, as amended, and our bylaws. These indemnification agreements provide, among other things, that we will indemnify our directors and officers for certain expenses, including damages, judgments, fines, penalties, settlements and costs and attorneys’ fees and disbursements, incurred by a director or officer in any claim, action or proceeding arising in his or her capacity as a director or officer of the company or in connection with service at our request for another corporation or entity. The indemnification agreements also provide for procedures that will apply in the event that a director or officer makes a claim for indemnification.
 
We also maintain a directors’ and officers’ insurance policy pursuant to which our directors and officers are insured against liability for actions taken in their capacities as directors and officers.
 
SEC Position on Indemnification for Securities Act Liabilities
 
Insofar as indemnification for liabilities arising under the Securities Act may be permitted for directors, officers or persons controlling our company, we understand that it is the SEC’s opinion that such indemnification is against public policy as expressed in the Securities Act and therefore is unenforceable.

the currency of denomination;
 
 
the designation of the currency, currencies or currency units in which payment of principal and, if applicable, premium and interest, will be made;

We may also issue debt securities in bearer form, with or without coupons. If we issue discount debt securities or debt securities in bearer form, we will describe material U.S. federal income tax considerations and other material special considerations which apply to these debt securities in the applicable prospectus supplement.
 
We may issue debt securities denominated in or payable in a foreign currency or currencies or a foreign currency unit or units. If we do, we will describe the restrictions, elections, and general tax considerations relating to the debt securities and the foreign currency or currencies or foreign currency unit or units in the applicable prospectus supplement.

Transfer and Exchange
 
We may issue debt securities that will be represented by either:
 
 
 
“book-entry securities,” which means that there will be one or more global securities registered in the name of a depositary or a nominee of a depositary; or

You will not be charged a service charge for any transfer or exchange of certificated debt securities but may be required to pay an amount sufficient to cover any tax or other governmental charge payable in connection with such transfer or exchange.
 
You may effect the transfer of certificated debt securities and of the right to receive the principal of, premium, and/or interest, if any, on the certificated debt securities only by surrendering the certificate representing the certificated debt securities and having us or the trustee issue a new certificate to the new holder.
 
 
13
 
 
 
Global Securities
 
If we decide to issue debt securities in the form of one or more global securities, then we will register the global securities in the name of the depositary for the global securities or the nominee of the depositary, and the global securities will be delivered by the trustee to the depositary for credit to the accounts of the holders of beneficial interests in the debt securities.
 
The prospectus supplement will describe the specific terms of the depositary arrangement for debt securities of a series that are issued in global form. None of us, the trustee, any payment agent or the security registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global debt security or for maintaining, supervising or reviewing any records relating to these beneficial ownership interests.
 
No Protection in the Event of Change of Control
 
The indenture does not have any covenants or other provisions providing for a put or increased interest or otherwise that would afford holders of our debt securities additional protection in the event of a recapitalization transaction, a change of control, or a highly leveraged transaction. If we offer any covenants or provisions of this type with respect to any debt securities covered by this prospectus, we will describe them in the applicable prospectus supplement.
 
Covenants
 
Unless otherwise indicated in this prospectus or the applicable prospectus supplement, our debt securities will not have the benefit of any covenants that limit or restrict our business or operations, the pledging of our assets or the incurrence by us of indebtedness. We will describe in the applicable prospectus supplement any material covenants in respect of a series of debt securities.
 
Consolidation, Merger and Sale of Assets
 
The form of indenture provides that we will not consolidate with or merge into any other person or convey, transfer, sell or lease our properties and assets substantially as an entirety to any person, unless:
 
 
 
the person formed by the consolidation or into or with which we are merged or the person to which our properties and assets are conveyed, transferred, sold or leased, is a corporation organized and existing under the laws of the U.S., any state or the District of Columbia or a corporation or comparable legal entity organized under the laws of a foreign jurisdiction and, if we are not the surviving person, the surviving person has expressly assumed all of our obligations, including the payment of the principal of and, premium, if any, and interest on the debt securities and the performance of the other covenants under the indenture; and
 
 
 
 
 
 
immediately before and immediately after giving effect to the transaction, no event of default, and no event which, after notice or lapse of time or both, would become an event of default, has occurred and is continuing under the indenture.
 
Events of Default
 
Unless otherwise specified in the applicable prospectus supplement, the following events will be events of default under the indenture with respect to debt securities of any series:
 
 
 
we fail to pay any principal or premium, if any, when it becomes due;
 
 
we fail to pay any interest within 30 days after it becomes due;
 
 
we fail to observe or perform any other covenant in the debt securities or the indenture for 60 days after written notice specifying the failure from the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of that series; and
 
 
certain events involving bankruptcy, insolvency or reorganization of us or any of our significant subsidiaries.
 
The trustee may withhold notice to the holders of the debt securities of any series of any default, except in payment of principal of or premium, if any, or interest on the debt securities of a series, if the trustee considers it to be in the best interest of the holders of the debt securities of that series to do so.
 
 
14
 
 
If an event of default (other than an event of default resulting from certain events of bankruptcy, insolvency or reorganization) occurs, and is continuing, then the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of any series may accelerate the maturity of the debt securities. If this happens, the entire principal amount, plus the premium, if any, of all the outstanding debt securities of the affected series plus accrued interest to the date of acceleration will be immediately due and payable. At any time after the acceleration, but before a judgment or decree based on such acceleration is obtained by the trustee, the holders of a majority in aggregate principal amount of outstanding debt securities of such series may rescind and annul such acceleration if:
  
 
 
all events of default (other than nonpayment of accelerated principal, premium or interest) have been cured or waived;
 
 
all lawful interest on overdue interest and overdue principal has been paid; and
 
 
the rescission would not conflict with any judgment or decree.
 
In addition, if the acceleration occurs at any time when we have outstanding indebtedness that is senior to the debt securities, the payment of the principal amount of outstanding debt securities may be subordinated in right of payment to the prior payment of any amounts due under the senior indebtedness, in which case the holders of debt securities will be entitled to payment under the terms prescribed in the instruments evidencing the senior indebtedness and the indenture.
 
If an event of default resulting from certain events of bankruptcy, insolvency or reorganization occurs, the principal, premium and interest amount with respect to all of the debt securities of any series will be due and payable immediately without any declaration or other act on the part of the trustee or the holders of the debt securities of that series.
 
The holders of a majority in principal amount of the outstanding debt securities of a series will have the right to waive any existing default or compliance with any provision of the indenture or the debt securities of that series and to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, subject to certain limitations specified in the indenture.
 
No holder of any debt security of a series will have any right to institute any proceeding with respect to the indenture or for any remedy under the indenture, unless:
 
 
 
the holder gives to the trustee written notice of a continuing event of default;
 
 
the holders of at least 25% in aggregate principal amount of the outstanding debt securities of the affected series make a written request and offer reasonable indemnity to the trustee to institute a proceeding as trustee;
 
 
the trustee fails to institute a proceeding within 60 days after such request; and
 
 
the holders of a majority in aggregate principal amount of the outstanding debt securities of the affected series do not give the trustee a direction inconsistent with such request during such 60-day period.
 
These limitations do not, however, apply to a suit instituted for payment on debt securities of any series on or after the due dates expressed in the debt securities.
 
We will periodically deliver certificates to the trustee regarding our compliance with our obligations under the indenture.
 
Modification and Waiver
 
From time to time, we and the trustee may, without the consent of holders of the debt securities of one or more series, amend the indenture or the debt securities of one or more series, or supplement the indenture, for certain specified purposes, including:
 
 
 
to provide that the surviving entity following a change of control permitted under the indenture will assume all of our obligations under the indenture and debt securities;
 
 
to provide for certificated debt securities in addition to uncertificated debt securities;
 
 
to comply with any requirements of the SEC under the Trust Indenture Act of 1939;
 
 
to provide for the issuance of and establish the form and terms and conditions of debt securities of any series as permitted by the indenture;
 
 
to cure any ambiguity, defect or inconsistency, or make any other change that does not materially and adversely affect the rights of any holder; and
 
 
to appoint a successor trustee under the indenture with respect to one or more series.

From time to time we and the trustee may, with the consent of holders of at least a majority in principal amount of an outstanding series of debt securities, amend or supplement the indenture or the debt securities series, or waive compliance in a particular instance by us with any provision of the indenture or the debt securities. We may not, however, without the consent of each holder affected by such action, modify or supplement the indenture or the debt securities or waive compliance with any provision of the indenture or the debt securities in order to:
 
 
 
reduce the amount of debt securities whose holders must consent to an amendment, supplement, or waiver to the indenture or such debt security;
 
 
reduce the rate of or change the time for payment of interest or reduce the amount of or postpone the date for payment of sinking fund or analogous obligations;
 
 
reduce the principal of or change the stated maturity of the debt securities;
 
 
make any debt security payable in money other than that stated in the debt security;
 
 
change the amount or time of any payment required or reduce the premium payable upon any redemption, or change the time before which no such redemption may be made;
 
 
waive a default in the payment of the principal of, premium, if any, or interest on the debt securities or a redemption payment;
 
 
waive a redemption payment with respect to any debt securities or change any provision with respect to redemption of debt securities; or
 
 
take any other action otherwise prohibited by the indenture to be taken without the consent of each holder affected by the action.
 
Defeasance of Debt Securities and Certain Covenants in Certain Circumstances
 
The indenture permits us, at any time, to elect to discharge our obligations with respect to one or more series of debt securities by following certain procedures described in the indenture. These procedures will allow us either:
 
 
 
to defease and be discharged from any and all of our obligations with respect to any debt securities, except for the following obligations (which discharge is referred to as “legal defeasance”):
 
 
(1)
 
to register the transfer or exchange of such debt securities;
 
(2)
 
to replace temporary or mutilated, destroyed, lost or stolen debt securities;
 
(3)
 
to compensate and indemnify the trustee; or
 
(4)
 
to maintain an office or agency in respect of the debt securities and to hold monies for payment in trust; or
 
 
 
to be released from our obligations with respect to the debt securities under certain covenants contained in the indenture, as well as any additional covenants which may be contained in the applicable supplemental indenture (which release is referred to as “covenant defeasance”).
 
In order to exercise either defeasance option, we must deposit with the trustee or other qualifying trustee, in trust for that purpose:
 
 
 
money;
 
 
U.S. Government Obligations (as described below) or Foreign Government Obligations (as described below) that through the scheduled payment of principal and interest in accordance with their terms will provide money; or
 
 
a combination of money and/or U.S. Government Obligations and/or Foreign Government Obligations sufficient in the written opinion of a nationally-recognized firm of independent accountants to provide money;
 
that, in each case specified above, provides a sufficient amount to pay the principal of, premium, if any, and interest, if any, on the debt securities of the series, on the scheduled due dates or on a selected date of redemption in accordance with the terms of the indenture.
 
 
16
 
 
In addition, defeasance may be effected only if, among other things:
 
 
 
in the case of either legal or covenant defeasance, we deliver to the trustee an opinion of counsel, as specified in the indenture, stating that as a result of the defeasance neither the trust nor the trustee will be required to register as an investment company under the Investment Company Act of 1940;
 
 
in the case of legal defeasance, we deliver to the trustee an opinion of counsel stating that we have received from, or there has been published by, the Internal Revenue Service a ruling to the effect that, or there has been a change in any applicable federal income tax law with the effect that (and the opinion shall confirm that), the holders of outstanding debt securities will not recognize income, gain or loss for U.S. federal income tax purposes solely as a result of such legal defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner, including as a result of prepayment, and at the same times as would have been the case if legal defeasance had not occurred;
 
 
in the case of covenant defeasance, we deliver to the trustee an opinion of counsel to the effect that the holders of the outstanding debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if covenant defeasance had not occurred; and
 
 
certain other conditions described in the indenture are satisfied.
 
If we fail to comply with our remaining obligations under the indenture and applicable supplemental indenture after a covenant defeasance of the indenture and applicable supplemental indenture, and the debt securities are declared due and payable because of the occurrence of any undefeased event of default, the amount of money and/or U.S. Government Obligations and/or Foreign Government Obligations on deposit with the trustee could be insufficient to pay amounts due under the debt securities of the affected series at the time of acceleration. We will, however, remain liable in respect of these payments.
 
The term “U.S. Government Obligations” as used in the above discussion means securities that are direct obligations of or non-callable obligations guaranteed by the United States of America for the payment of which obligation or guarantee the full faith and credit of the United States of America is pledged.
 
The term “Foreign Government Obligations” as used in the above discussion means, with respect to debt securities of any series that are denominated in a currency other than U.S. dollars, (1) direct obligations of the government that issued or caused to be issued such currency for the payment of which obligations its full faith and credit is pledged or (2) obligations of a person controlled or supervised by or acting as an agent or instrumentality of such government the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by that government, which in either case under clauses (1) or (2), are not callable or redeemable at the option of the issuer.
 
Regarding the Trustee
 
We will identify the trustee with respect to any series of debt securities in the prospectus supplement relating to the applicable debt securities. You should note that if the trustee becomes a creditor of ours, the indenture and the Trust Indenture Act of 1939 limit the rights of the trustee to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim, as security or otherwise. The trustee and its affiliates may engage in, and will be permitted to continue to engage in, other transactions with us and our affiliates. If, however, the trustee acquires any “conflicting interest” within the meaning of the Trust Indenture Act of 1939, it must eliminate such conflict or resign.
 
The holders of a majority in principal amount of the then outstanding debt securities of any series may direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee. If an event of default occurs and is continuing, the trustee, in the exercise of its rights and powers, must use the degree of care and skill of a prudent person in the conduct of his or her own affairs. Subject to that provision, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any of the holders of the debt securities, unless they have offered to the trustee reasonable indemnity or security.
