ITEM 1A . Risk Factors

Our business, financial condition and operating results can be affected by several factors, whether currently known or unknown, many of which are not exclusively within our control, including but not limited to those described below, any one or more of which could, directly or indirectly, cause our actual financial condition and operating results to differ materially from historical or anticipated future financial condition and operating results. Any of these factors, in whole or in part, could materially and adversely affect our business, financial condition, operating results and stock price. We urge investors to carefully consider the risk factors described below in evaluating the information in this report.

Risk Factors That May Affect Our Business

We receive a significant portion of our revenues from Buffalo Wild Wings corporate-owned restaurants and its franchisees, and, absent an extension, our relationship will terminate in November 2019.

For the year ended December 31, 2018, Buffalo Wild Wings corporate-owned restaurants and its franchisees accounted for approximately 44%, or $10,180,000, of our total revenue. As of that date, approximately $552,000 was included in accounts receivable. In October 2018, Buffalo Wild Wings informed us that it determined not to rollout our order, payment and guest insights functionality and that its relationship with us would continue in accordance with existing agreements we entered into in the ordinary course of business, and which terminate in accordance with their terms in November 2019. If we do not extend the Buffalo Wild Wings relationship beyond November 2019 or add network subscribers to sufficiently offset the subscription revenue we receive and have received in recent years from Buffalo Wild Wings corporate-owned restaurants and its franchisees, we expect our subscription revenue to materially decrease beginning in the first quarter of 2020, which could materially and adversely affect our operating results and cash flows. In addition, the inability to demonstrate Buffalo Wild Wings as a strategic user of our expanded functionality tablet platform system could negatively impact achievement of our chain customer site growth goals. Likewise, if any other customer who may in the future represent a significant portion of our revenue were to breach or terminate their subscriptions or otherwise decrease the amount of business they transact with us, we could lose a significant portion of our revenues and cash flow.

Our cash flow may not cover our capital needs and we may need to raise additional funds in the future. Such funds may not be available when needed, on acceptable terms or at all and, if available, may dilute current stockholders.

As of December 31, 2018, we had cash, cash equivalents and restricted cash of $2,786,000. We have borrowed substantially all amounts available to us under existing credit facilities and, subject to limited exceptions, our loan and security agreement with Avidbank prohibits us from borrowing additional amounts from other lenders. As of December 31, 2018, $3,750,000 was outstanding under that loan agreement, of which $1,000,000 was recorded in current portion of long-term debt and $2,750,000 was recorded in long-term debt on our balance sheet, which is gross of any unamortized debt issuance costs that are recorded as a reduction of long-term debt. The loan matures on September 30, 2022. We must make monthly principal payments of approximately $83,000 plus accrued and unpaid interest on the last business day of each month commencing on October 31, 2018 and through maturity.

Our ability to meet our debt service obligations and to fund working capital, capital expenditures and investments in our business, will depend upon our future performance, which will depend on many factors, including:

In addition, to fully execute on our long-term strategic initiatives discussed above under the section entitled “ITEM 1. Business—Our Strategy,” we believe we will likely require additional funding in the future.

We cannot ensure that we will generate cash flow from operations in an amount sufficient to enable us to meet our debt service obligations or to fund our working capital needs, capital expenditures and investments in our business. Avidbank has a first-priority security interest in all our existing and future personal property. If we default on our monthly payment obligations to Avidbank, and our debt obligations become immediately due and payable in full, Avidbank may dispose of our personal property to satisfy our payment obligations. If we need to raise additional funds in the future, such funds may not be available when needed, on acceptable terms, or at all. Furthermore, if we issue equity or debt securities to raise additional funds, our existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences, and privileges senior to those of our existing stockholders. If we cannot raise funds on acceptable terms, or at all, we may not be able to continue to develop and implement our platform and product line, develop or enhance our other products and services, successfully execute our business plan or any or all of our strategic initiatives, take advantage of future opportunities, or respond to competitive pressures or unanticipated customer requirements.

We have experienced significant losses, and we may incur significant losses in the future.

We have a history of significant losses, including net losses of $259,000 and $1,077,000 for the years ended December 31, 2018 and 2017, respectively, and have an accumulated deficit of $129,394,000 as of December 31, 2018. We may also incur future operating and net losses, due in part to expenditures required to continue to implement our business strategies, including the continued development and implementation of our technology platform and product line. Despite significant expenditures, we may not achieve or maintain profitability. Even if we achieve profitability, the level of profitability cannot be predicted and may vary significantly from quarter to quarter and year to year. See also “—Risks Relating to the Market for Our Common Stock—If we are again determined to be non-compliant with any of the NYSE American continued listing standards within twelve months of December 14, 2018, depending on the nature of such non-compliance, NYSE Regulation may truncate the compliance procedures available to us or immediately initiate delisting proceedings,” below.

We may not compete effectively within the highly competitive and evolving interactive games, entertainment and marketing services industries.

We face intense competition in the markets in which we operate. We face significant competition for entertainment and marketing services in hospitality venues from other companies offering similar content and services. Our services also compete with games, apps and other forms of entertainment offerings available directly to consumers on their smart phones and tablets. See “ITEM 1. Business—Competition,” above. Some of our current and potential competitors enjoy substantial competitive advantages, including greater financial resources for competitive activities, such as content development and programming, research and development, strategic acquisitions, alliances, joint ventures, and sales and marketing. As a result, our current and potential competitors may respond more quickly and effectively than we can to new or changing opportunities, technologies, standards, or consumer preferences.

The increased availability of the internet and wireless networks provides consumers with an increasing number of alternatives to our entertainment offerings. With this increasing competition and the rapid pace of change in product and service offerings, we must be able to compete in terms of technology, content, and management strategy. If we fail to provide competitive, engaging, quality services and products, we will lose revenues to competing companies and technologies. Increased competition may also result in price reductions, fewer customer orders, reduced gross margins, longer sales cycles, reduced revenues, and loss of market share.

New products and rapid technological change, especially in the mobile and wireless markets, may render our operations obsolete or noncompetitive.

The emergence of new entertainment products and technologies, changes in consumer preferences, the adoption of new industry standards, and other factors may limit the life cycle and market penetration of our technologies, products, and services. In particular, the mobile and wireless device, content, applications, social media, and entertainment markets are highly competitive and rapidly changing. Accordingly, our future performance will depend on our ability to:

If we do not compete successfully in developing new products and keep pace with rapid technological change, we will be unable to achieve profitability or sustain a meaningful market position.

We may not succeed in developing and marketing new products and services that respond to technological and competitive developments, changing customer needs, and consumer preferences. We may have to incur substantial costs to modify or adapt our products or services to respond to these developments, customer needs, and changing preferences. We must be able to incorporate new technologies into the products we design and develop to address the increasingly complex and varied needs of our customer base. Any significant delay or failure in developing new or enhanced technology, including new product and service offerings, could result in a loss of actual or potential market share and a decrease in revenues.

If we fail to comply with our financial covenants to Avidbank, it may declare a default, which could lead to all payment obligations becoming immediately due and payable and have a material adverse effect on our financial condition and business.

We must comply with financial covenants our loan and security agreement with Avidbank: our EBITDA must be at least $1,000,000 for the trailing six-month period as of the last day of each fiscal quarter, and the aggregate amount of unrestricted cash we have in deposit accounts or securities accounts maintained with Avidbank must be not less than $2,000,000 at all times. See “PART II—ITEM 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources,” below.

As of December 31, 2018, we were in compliance with these covenants. However, there can be no assurance we will be in compliance with these covenants in the future, including due to events or conditions outside of our control. For example, fluctuations in our operating results, such as what may result if we don’t extend the Buffalo Wild Wings relationship beyond November 2019 or add network subscribers to sufficiently offset the subscription revenue we receive and have received in recent years from Buffalo Wild Wings corporate-owned restaurants and its franchisees, could result in violation of the adjusted EBITDA covenant. See “ We receive a significant portion of our revenues from Buffalo Wild Wings corporate-owned restaurants and its franchisees, and, absent an extension, our relationship will terminate in November 2019 ,” above.

If we fail to comply with our covenants, Avidbank may declare a default, which could lead to all payment obligations becoming immediately due and payable and have a material adverse effect on our financial condition and business. Avidbank has a first-priority security interest in all our existing and future personal property. Accordingly, in an event of a default, Avidbank could dispose of such property to satisfy our payment obligations.

We cannot assure you that our exploration of strategic alternatives will result in us pursuing a transaction or that any such transaction would be successfully completed, and there may be negative impacts on our business and stock price as a result of the process of exploring strategic alternatives.

On December 7, 2018, we announced that our board of directors is exploring and evaluating strategic alternatives focused on maximizing shareholder value, and that we engaged a financial advisor to assist in the process. The strategic process is ongoing. Our board of directors has not set a timetable for the strategic process nor has it made any decisions relating to any strategic alternatives at this time. These alternatives could include, among other things, a potential acquisition of our company or our assets, a transaction with a strategic partner involving one or more of our assets, or continuing to execute on our business plan. No assurance can be given as to the outcome of the process, including whether the process will result in a transaction or that any transaction that is agreed to will be completed. Whether the process will result in a transaction, and our ability to complete a transaction, if our board of directors decides to pursue one, will depend on numerous factors, some of which are beyond our control, including the interest of potential acquirers or strategic partners in a potential transaction with our company, the value potential acquirers or strategic partners attribute to our business and its prospects, including in light of the potential end of our relationship with Buffalo Wild Wings corporate-owned restaurants and its franchisees, market conditions, and industry trends. Our stock price may be adversely affected if the process does not result in a transaction or if a transaction is not completed. Even if a transaction is completed, there can be no assurance that it will be successful or have a positive effect on shareholder value. Our board of directors may also determine that no transaction is in the best interest of our stockholders.

In addition, our financial results and operations may be adversely affected by the strategic process and by the uncertainty regarding its outcome. We have diverted the attention of management and our board of directors from our business operations to the process and have applied capital resources to the process that otherwise could have been used in our business operations, and we will continue to do so until the process is completed. We could incur substantial expenses associated with identifying and evaluating potential strategic alternatives, including those related to employee retention payments, equity compensation, severance pay and legal, accounting and financial advisory fees. In addition, the process could lead us to lose or fail to attract, retain and motivate key employees, and to lose or fail to attract customers or business partners, and could expose us to litigation in connection with the process or any resulting transaction. The public announcement of a strategic alternative may also yield a negative impact on operating results if prospective or existing service providers are reluctant to commit to new or renewal contracts or if existing customers decide to move their business to a competitor.

Further, we do not intend to disclose developments or provide updates on the progress or status of the strategic process until our board of directors deems further disclosure is appropriate or required. Accordingly, speculation regarding any developments related to the review of strategic alternatives and perceived uncertainties related to the future of our company could cause our stock price to fluctuate significantly.

A disruption in the supply of equipment could negatively impact our subscriptions and revenue.

During the fourth quarter of 2016, we began having an unaffiliated third party manufacture an Android-based tablet customized to our specifications. This third-party manufacturer also manufactures our tablet equipment—tablet charging trays and tablet cases. We have no alternative manufacturing source for our customized tablet or tablet equipment or alternatives for the tablet equipment.

If our sole manufacturer is delayed in delivering tablets to us, becomes unavailable, has product quality issues, or shortages occur, besides not realizing the benefits of having a tablet manufactured to our specifications, we would need to return to the historical third-party tablets or find an alternative device. Similarly, if our sole manufacturer is delayed in delivering the tablet equipment to us, becomes unavailable, has product quality issues, or shortages occur, we may not timely obtain replacement tablet equipment. Delays, unavailability of the tablet or tablet equipment, product quality issues and shortages could damage our reputation and customer loyalty, cause subscription cancellations, increase our expense and reduce our revenue. See also “ Our business could be adversely impacted if the sole manufacturer of our customized tablet and tablet equipment is not able to meet our manufacturing quality standards ,” below.

If our sole manufacturer and/or suppliers were to go out of business or otherwise become unable to meet our needs for reliable equipment, locating and qualifying alternate sources could take months, during which time our production could be delayed, and may, in some cases, require us to redesign our products and systems. Such delays and potentially costly re-sourcing and redesign could have a material adverse effect on our business, operating results, and financial condition.

Our business could be adversely impacted if the sole manufacturer of our customized tablet and tablet equipment cannot meet our manufacturing quality standards.

As discussed above, one unaffiliated third-party manufactures our customized tablet and tablet equipment. Continued improvement in supply-chain management and in manufacturing of our customized tablet and tablet equipment and manufacturing quality and product testing are important to our business. Flaws in the design and manufacturing of our customized tablet or tablet equipment or both (by us or our supplier) could result in substantial delays in shipment and in substantial repair, replacement or service costs, could damage our reputation and customer loyalty, could cause subscription cancellations, and could increase our expense and reduce our revenue. Costs associated with tablet or tablet equipment defects due to, for example, problems in our design and manufacturing processes, could include: (a) writing off the value of inventory; (b) disposing of items that cannot be fixed; (c) recalling items that have been shipped; and (d) providing replacements or modifications. These costs could be significant and may increase expenses and lower gross margin. There can be no assurance that our efforts to monitor, develop, modify and implement appropriate test and manufacturing processes for our tablet and related equipment will be sufficient to permit us to avoid quality issues. Significant quality issues could have a material adverse effect on our business, results of operations or financial condition.

If we do not adequately protect our proprietary rights and intellectual property or we are subjected to intellectual property claims by others, our business could be seriously damaged.

We rely on a combination of trademarks, copyrights, patents, and trade secret laws to protect our proprietary rights in our products. We have a few patents and patent applications pending in jurisdictions related to our business activities. Our pending patent applications and any future applications might not be approved. Moreover, our patents might not provide us with competitive advantages. Third parties might challenge our patents or trademarks or attempt to use infringing technologies or brands which could harm our ability to compete and reduce our revenues, as well as create significant litigation expense. In addition, patents and trademarks held by third parties might have an adverse effect on our ability to do business and could likewise result in significant litigation expense. Furthermore, third parties might independently develop similar products, duplicate our products or, to the extent patents are issued to us, design around those patents. Others may have filed and, in the future may file, patent applications that are similar or identical to ours. Such third-party patent applications might have priority over our patent applications. To determine the priority of inventions, we may have to participate in interference proceedings declared by the United States Patent and Trademark Office. Such interference proceedings could result in substantial cost to us.

We believe that the success of our business also depends on such factors as the technical expertise and innovative capabilities of our employees. It is our policy that all employees and consultants sign non-disclosure agreements and assignment of invention agreements. Our competitors, former employees, and consultants may, however, misappropriate our technology or independently develop technologies that are as good as or better than ours. Our competitors may also challenge or circumvent our proprietary rights. If we have to initiate or defend against an infringement claim to protect our proprietary rights, the litigation over any such claim, with or without merit, could be time-consuming and costly to us, adversely affecting our financial condition.

From time to time, we hire or retain employees or consultants who may have worked for other companies developing products similar to those that we offer. These other companies may claim that our products are based on their products and that we have misappropriated their intellectual property. Any such claim, with or without merit, could be time-consuming and costly to us, adversely affecting our financial condition.

We may be liable for the content and services we make available on our Buzztime network and the internet.

We make content and entertainment services available on our Buzztime network and the internet which includes games and game content, software, and a variety of other entertainment content. The availability of this content and services and our branding could result in claims against us based on a variety of theories, including defamation, obscenity, negligence, or copyright or trademark infringement. We could also be exposed to liability for third-party content accessed through the links from our websites to other websites. Federal laws may limit, but not eliminate, our liability for linking to third-party websites that include materials that infringe copyrights or other rights, so long as we comply with certain statutory requirements. We may incur costs to defend against claims related to either our own content or that of third parties, and our financial condition could be materially adversely affected if we are found liable for information that we make available. Implementing measures to reduce our exposure may require us to spend substantial resources and may limit the attractiveness of our services to users which would impair our profitability and harm our business operations.

We may not grow our subscription revenue and successfully implement our other business strategies.

Our success depends on our ability to increase market awareness and encourage the adoption of the Buzztime brand and our Buzztime network among hospitality venues such as restaurants, sports bars, taverns and pubs, and within the interactive game player community. Our success also depends on our ability to improve customer retention. We may not be able to leverage our resources to expand awareness of and demand for our Buzztime network. In addition, our efforts to improve our game platform and content may not succeed in generating additional demand for our products or in strengthening the loyalty and retention of our existing customers. The degree of market adoption of our Buzztime network will depend on many factors, including consumer preferences, the availability and quality of competing products and services, and our ability to leverage our brand.

Our success also depends on our ability to implement our other business strategies, which include developing our tablet platform that allows for consumer play across the digital platform, developing more premium content that allow us to grow the revenue stream directly from consumers, developing dynamic menuing and point-of-sale, or POS, integration competency, and growing our marketing services and sponsorship revenues. Implementing these strategies will require us to dedicate significant resources to, among other things, fully developing and implementing our tablet platform and product line, expanding our other product offerings, customizing our products and services to meet the unique needs of select accounts, and expanding and improving our marketing services and promotional efforts. We may not successfully implement these strategies as planned.

Our products and services are subject to government regulations that may restrict our operations or cause demand for our products to decline significantly.

In addition to laws and regulations applicable to businesses generally, we are also subject to laws and regulations that apply specifically to the interactive entertainment and product marketing industries. In addition, we operate games of chance and skill, and we award nominal cash prizes to winners of certain games and may provide items of nominal value (e.g., key chains, etc.) to venues who may award such items to consumers. These games are regulated in many jurisdictions and the laws and regulations vary from jurisdiction to jurisdiction. See “ITEM 1. BUSINESS—Government Regulations.”

We may find it necessary to eliminate, modify, suspend, or cancel certain features of our offerings (including the games we offer) in certain jurisdictions based on the adoptions of new laws and regulations or changes in law or regulations or the enforcement thereof, which could result in additional development costs and/or the loss of customers and revenue.

Communication or other system failures could result in customer cancellations and a decrease in our revenues.

We rely on continuous operation of our information technology and communications systems, and those of a variety of third parties, to communicate with and to distribute our services to the locations of our network subscribers. We currently transmit our data to our customers via broadband internet connections including telephone and cable TV networks. Both our communications systems and those of third parties on which we rely are vulnerable to damage or interruption from earthquakes, terrorist attacks, floods, storms, fires, power loss, telecommunications and other network failures, equipment failures, computer viruses, computer denial of service or other attacks, and other causes. These systems are also subject to break-ins, sabotage, vandalism, and to other disruptions, for example if we or the operators of these systems and system facilities have financial difficulties. Some of our systems are not fully redundant, and our system protections and disaster recovery plans cannot prevent all outages, errors, or data losses. In addition, our services and systems are highly technical and complex and may contain errors or other vulnerabilities. Any errors or vulnerabilities in our products and services, damage to or failure of our systems, any natural or man-made disaster, or other unanticipated problems at our facilities or those of a third party, could result in lengthy interruptions in our service to our customers, which could reduce our revenues and cash flow, and damage our brand. Any interruption in communications or failure of proper hardware or software function at our or our customers’ venues could also decrease customer loyalty and satisfaction and result in a cancellation of our services.

Our success depends on our ability to recruit and retain skilled professionals.

Our business requires experienced programmers, creative designers, application developers, and sales and marketing personnel. Our success will depend on identifying, hiring, training, and retaining such experienced and knowledgeable professionals. We must recruit and retain talented professionals for our business to grow. There is significant competition for the individuals with the skills required to develop the products and perform the services we offer. We may not attract enough qualified individuals to sustain and grow our business, and we may not succeed in motivating and retaining the individuals we do attract. If we cannot attract, motivate, and retain qualified technical and sales and marketing professionals, our business, financial condition, and results of operations will suffer.

We have incurred significant net operating loss carryforwards that we will likely be unable to use.

At December 31, 2018, we had net operating loss (“NOL”) carryforwards of approximately $66,572,000 available for federal income tax purposes, which will continue expiring in 2019, and of approximately $36,044,000 available for state income tax purposes, which will continue expiring in 2019. We believe that our ability to utilize our NOL carryforwards may be substantially restricted by the passage of time and the limitations of Section 382 of the Internal Revenue Code, which apply when there are certain changes in ownership of a corporation. To the extent we begin to realize significant taxable income, these Section 382 limitations may result in our incurring federal income tax liability notwithstanding the existence of otherwise available NOL carryforwards. We performed a Section 382 analysis through December 31, 2018 to determine the impact of any changes in ownership. This analysis indicates that no ownership change occurred that would limit the use of the NOLs. We established a full valuation allowance for substantially all of our deferred tax assets, including the NOL carryforwards, since we do not believe we are likely to generate future taxable income to realize these assets.

We are subject to cybersecurity risks and incidents.

Our business involves transmitting payment information of our customers and certain personal information of consumers (such as their name, date of birth, and email address). In the future, we may store and transmit additional personal information of consumers, particularly as the services of the tablet platform become more advanced to include POS integration. While we have implemented measures designed to prevent security breaches and cyber incidents, any failure of these measures and/or any material security breaches, theft, misplaced or lost data, programming errors, employee errors and/or malfeasance could lead to the compromise of sensitive, confidential or personal data or information, improper use of our systems, software solutions or networks, unauthorized access, use, disclosure, modification or destruction of information, system downtimes, and operational disruptions. In addition, a cyber-related attack could result in other negative consequences, including damage to our reputation or competitiveness, remediation or increased protection costs, litigation or regulatory action.

We could become subject to additional regulations and compliance requirements as we introduce features in direct payments from consumers.

In preparation for expanding features and functionality to our tablet platform that involve us accepting credit card and other forms of payments directly from consumers, we certified our compliance with Payment Card Industry (“PCI”) Data Security Standard v3.1 as a service provider, and will have to do so annually. Compliance with additional regulations and requirements may be difficult for us; thereby limiting our ability to grow the amount of revenue we receive directly from consumers. In addition to these additional regulations and requirements, if we fail to comply with the rules or requirements of any provider of a payment method we accept, if the volume of fraud in our transactions limits or terminates our rights to use payment methods we accept, or if a data breach occurs relating to our payment systems, we may, among other things, be subject to fines or higher transaction fees and may lose, or face restrictions placed upon, our ability to accept credit card and debit card payments from consumers.

Risks Relating to the Market for Our Common Stock

If we are again determined to be non-compliant with any of the NYSE American continued listing standards within twelve months of December 14, 2018, depending on the nature of such non-compliance, NYSE Regulation may truncate the compliance procedures available to us or immediately initiate delisting proceedings.

On December 14, 2018, as previously reported, we received a letter from NYSE Regulation Inc. notifying us that we have regained compliance with Section 1003(a)(iii) of the NYSE American Company Guide. As previously reported, NYSE Regulation previously notified us that we were not in compliance with Section 1003(a)(iii) because we reported stockholders’ equity of less than $6 million as of December 31, 2017 and had net losses in five of our most recent fiscal years ended December 31, 2017.

In accordance with Section 1009(h) of the Company Guide, if we are again determined to be below any of the NYSE American continued listing standards within twelve months of December 14, 2018, NYSE Regulation will examine the relationship between the two incidents of noncompliance and re-evaluate our method of financial recovery from the first incident. NYSE Regulation will then take appropriate action, which, depending on the circumstances, may include truncating the compliance procedures described in Section 1009 of the Company Guide or immediately initiating delisting proceedings.

We can give no assurances we can maintain the listing of our common stock on the NYSE American. Our common stock could be delisted because we fall below compliance with any NYSE American listing standards. In addition, we may determine to pursue business opportunities or grow our business at levels or on timelines that reduces our stockholders’ equity below the level required to maintain compliance with NYSE American continued listing standards. The delisting of our common stock for whatever reason could, among other things, substantially impair our ability to raise additional capital; result in losing institutional investor interest and fewer financing opportunities for us; and/or result in potential breaches of representations or covenants of our warrants or other agreements pursuant to which we made representations or covenants relating to our compliance with applicable listing requirements. Claims related to any such breaches, with or without merit, could result in costly litigation, significant liabilities and diversion of our management’s time and attention and could have a material adverse effect on our financial condition, business and results of operations. In addition, the delisting of our common stock for whatever reason may materially impair our stockholders’ ability to buy and sell shares of our common stock and could have an adverse effect on the market price of, and the efficiency of the trading market for, our common stock.

If our common stock were delisted and determined to be a “penny stock,” a broker-dealer may find it more difficult to trade our common stock and an investor may find it more difficult to acquire or dispose of our common stock in the secondary market.

If our common stock were delisted or suspended from trading on the NYSE American, it may be subject to the so-called “penny stock” rules. The SEC has adopted regulations that define a “penny stock” to be any equity security that has a market price per share of less than $5.00, subject to certain exceptions, such as any securities listed on a national securities exchange. For any transaction involving a “penny stock,” unless exempt, the rules impose additional sales practice requirements on broker-dealers, subject to certain exceptions. If our common stock were delisted and determined to be a “penny stock,” a broker-dealer may find it more difficult to trade our common stock and an investor may find it more difficult to acquire or dispose of our common stock.

The market price of our common stock historically has been and likely will continue to be highly volatile and our common stock is thinly traded.

The market price for our common stock historically has been highly volatile, and the market for our common stock has from time to time experienced significant price and volume fluctuations, based both on our operating performance and for reasons that appear to us unrelated to our operating performance. Our stock is also thinly traded, which can affect market volatility, which could significantly affect the market price of our common stock without regard to our operating performance. In addition, the market price of our common stock may fluctuate significantly in response to several factors, including:

The realization of any of the foregoing could have a dramatic and adverse impact on the market price of our common stock.

Future sales of substantial amounts of our common stock in the public market or the anticipation of such sales could have a material adverse effect on then-prevailing market prices.

As of December 31, 2018, there were approximately (1) 147,000 shares of common stock reserved for issuance upon the exercise of outstanding stock options at exercise prices ranging from $4.30 to $30.50 per share, (2) 61,000 shares of common stock reserved for issuance upon the settlement of outstanding restricted stock units, and (3) 156,000 shares of our Series A Preferred Stock outstanding which, based on their current conversion price, would convert into approximately 12,000 shares of common stock. Registration statements registering the shares of common stock underlying the outstanding options and restricted stock units are currently effective. Generally, the shares of common stock issuable upon conversion of the Series A Preferred Stock, which the holders may do at any time, may be sold under Rule 144 of the Securities Act of 1933. Accordingly, a significant number of shares of our common stock could be sold at any time. Depending upon market liquidity at the time our common stock is resold by the holders thereof, such resales could cause the trading price of our common stock to decline. In addition, the sale of a substantial number of shares of our common stock, or anticipation of such sales, could make it more difficult for us to obtain future financing. To the extent the trading price of our common stock at the time any of our outstanding options are exercised exceeds their exercise price or at the time any of our outstanding shares of Series A Preferred stock are converted exceeds their conversion price, such exercise or conversion will have a dilutive effect on our stockholders.

Raising additional capital may cause dilution to our existing stockholders and may restrict our operations.

We may raise additional capital at any time and may do so through one or more financing alternatives, including public or private sales of equity or debt securities directly to investors or through underwriters or placement agents. We have a shelf registration statement on file under which we could currently sell up to approximately $21.6 million worth of securities. See also “ Our ability to raise capital may be limited by applicable laws and regulations ,” below. Raising capital through the issuance of common stock (or securities convertible into or exchangeable or exercisable for shares of our common stock) may depress the market price of our stock and may substantially dilute our existing stockholders. In addition, our board of directors may issue preferred stock with rights, preferences and privileges senior to those of the holders of our common stock. Debt financings could involve covenants that restrict our operations. These restrictive covenants may include limitations on additional borrowing and specific restrictions on the use of our assets, as well as prohibitions on our ability to create liens or make investments and may, among other things, preclude us from making distributions to stockholders (either by paying dividends or redeeming stock) and taking other actions beneficial to our stockholders. In addition, investors could impose more one-sided investment terms on companies that have or are perceived to have limited remaining funds or limited ability to raise additional funds. The lower our cash balance, the more difficult it is likely to be for us to raise additional capital on commercially reasonable terms, or at all.

Our ability to raise capital may be limited by applicable laws and regulations.

Over the past few years we have raised capital through the sale of our equity securities. The offerings we completed in April 2014, November 2016, March 2017, April 2017 and June 2018 were equity offerings conducted under the “shelf” registration statement on Form S-3. Using a shelf registration statement on Form S-3 to raise additional capital generally takes less time and is less expensive than other means, such as conducting an offering under a Form S-1 registration statement. However, our ability to raise capital using a shelf registration statement may be limited by, among other things, SEC rules and regulations. Under SEC rules and regulations, we must meet certain requirements to use a Form S-3 registration statement to raise capital without restriction as to the amount of the market value of securities sold thereunder. One such requirement is that we periodically evaluate the market value of our outstanding shares of common stock held by non-affiliates, or public float, and if, at an evaluation date, our public float is less than $75.0 million, then the aggregate market value of securities sold by us or on our behalf under the Form S-3 in any 12-month period is limited to an aggregate of one-third of our public float. Based on the closing price of our common stock on March 20, 2019, the highest closing price of our common stock within the past 60 days, our public float is approximately $7.8 million and therefore we are currently subject to the one-third of our public float limitation. Assuming our public float remains the same amount the next time we must evaluate it, we will only be able to sell up to approximately $1.0 million if we seek to use our shelf registration statement on or before June 29, 2019, and we will only be able to sell up to approximately $2.6 million if we seek to use our shelf registration statement after June 29, 2019, in each case, assuming we sell no securities using our shelf registration statement before then. If our ability to use our shelf registration statement for a primary offering of our securities is limited to one-third of our public float, we may conduct such an offering pursuant to an exemption from registration under the Securities Act or under a Form S-1 registration statement, and we would expect either alternative to increase the cost of raising additional capital relative to utilizing a Form S-3 registration statement.

In addition, under SEC rules and regulations, our common stock must be listed and registered on a national securities exchange in order to utilize a Form S-3 registration statement (i) for a primary offering, if our public float is not at least $75.0 million as of a date within 60 days prior to the date of filing the Form S-3 or a re-evaluation date, whichever is later, and (ii) to register the resale of our securities by persons other than us (i.e., a resale offering). While currently our common stock is listed on the NYSE American, there can be no assurance we can maintain such listing. See also our risk factor “Although we have regained compliance with the continued listing standards of the NYSE American with which we were previously not compliant, if we are again determined to be non-compliant with any of its continued listing standards within twelve months of December 14, 2018, depending on the nature of such non-compliance, NYSE Regulation may truncate the compliance procedures available to us or immediately initiate delisting proceedings” above.

Our ability to timely raise sufficient additional capital also may be limited by the NYSE American’s stockholder approval requirements for transactions involving the issuance of our common stock or securities convertible into our common stock. For instance, the NYSE American requires that we obtain stockholder approval of any transaction involving the sale, issuance or potential issuance by us of our common stock (or securities convertible into our common stock) at a price less than the greater of book or market value, which (together with sales by our officers, directors and principal stockholders) equals 20% or more of our then outstanding common stock, unless the transaction is considered a “public offering” by the NYSE American staff. In addition, certain prior sales by us may be aggregated with any offering we may propose in the future, further limiting the amount we could raise in any future offering not considered a public offering by the NYSE American staff and involves the sale, issuance or potential issuance by us of our common stock (or securities convertible into our common stock) at a price less than the greater of book or market value. The NYSE American also requires that we obtain stockholder approval if the issuance or potential issuance of additional shares will be considered by the NYSE American staff to result in a change of control of our company.

Obtaining stockholder approval is a costly and time-consuming process. If we must obtain stockholder approval for a potential transaction, we would expect to spend substantial additional money and resources. In addition, seeking stockholder approval would delay our receipt of otherwise available capital, which may materially and adversely affect our ability to execute our business strategy, and there is no guarantee our stockholders ultimately would approve a proposed transaction. A public offering under the NYSE American rules typically involves broadly announcing the proposed transaction, which often depresses the issuer’s stock price. Accordingly, the price at which we could sell our securities in a public offering may be less, and the dilution existing stockholders experience may in turn be greater, than if we were able to raise capital through other means.

Our charter contains provisions that may hinder or prevent a change in control of our company, which could result in our inability to approve a change in control and potentially receive a premium over the current market value of your stock.

Certain provisions of our certificate of incorporation could make it more difficult for a third party to acquire control of us, even if such a change in control would benefit our stockholders, or to make changes in our board of directors. For example, our certificate of incorporation (i) prohibits stockholders from filling vacancies on our board of directors, calling special stockholder meetings, or taking action by written consent, and (ii) requires a supermajority vote of at least 80% of the total voting power of our outstanding shares, voting together as a single class, to remove our directors from office or to amend provisions relating to stockholders taking action by written consent or calling special stockholder meetings.

Additionally, our certificate of incorporation and restated bylaws contain provisions that could delay or prevent a change of control of our company. Some provisions:

These provisions could discourage third parties from taking control of our company. Such provisions may also impede a transaction in which you could receive a premium over then current market prices and your ability to approve a transaction that you consider in your best interest.

In addition, we are governed by Section 203 of the Delaware General Corporate Law, which may prohibit certain business combinations with stockholders owning 15% or more of our outstanding voting stock. These and other provisions in our certificate of incorporation, restated bylaws and Delaware law could make it more difficult for stockholders or potential acquirers to obtain control of our board of directors or initiate actions that are opposed by the then-current board of directors, including delaying or impeding a merger, tender offer, or proxy contest involving our company. Any delay or prevention of a change of control transaction or changes in our board of directors could cause the market price of our common stock to decline.
