We may not be able to meet demand for KLH from either internally raised or ocean harvest sources.

We are dependent upon a supply of Giant Keyhole Limpets (Megathura crenulata) for KLH production. The range of the Giant Keyhole Limpet in the wild is limited, and due to the lack of a regulated harvest, the wild stocks of Giant Keyhole Limpets are believed to be declining. If the wild stocks are depleted, and our hatchery and aquaculture operations are unable to produce sufficient supplies of captive Giant Keyhole Limpets to meet demand, it would have a negative effect on our operations and financial condition.

We may not be able to manufacture our products in commercial quantities and currently depend on third parties for certain steps in our manufacturing operations, which could prevent us from marketing our products.

The manufacture of pharmaceutical starting materials like KLH requires significant expertise, including the development of advanced manufacturing techniques and process controls that are GMP compliant. We may encounter difficulties in production or meeting GMP standards, particularly in scaling up production. These problems include difficulties with production costs and yields, quality control, including stability of the product and quality assurance testing, shortages of qualified personnel, as well as compliance with federal, state and foreign regulations.

In addition, we contract with third party vendors, including contract testing organizations and contract manufacturing organizations for testing of our products and for certain steps in the manufacture of some our products, and may be unable to monitor and establish or maintain relationships with qualified vendors in order to produce sufficient supplies of our finished products.

We are currently dependent upon a small number of contractors and locations for certain steps in our manufacturing operations, namely product release testing and vialing. We do not currently have backup manufacturing capacity for some of our key products. If we are unable to retain our current contractors, or are unable to obtain new contractors to provide manufacturing services in a timely manner and on similar terms, it will have a negative effect on our operations. Further, these contract manufacturers and testing organizations provide services to many biotechnology and research companies, and such third party contractors may not provide acceptable quality, quantity or costs required by us. In addition, they may not be able to provide the services required on a schedule acceptable to us. These issues may result in us being unable to manufacture our products in the required quantities or at an acceptable cost, which would have a negative effect on our operations and financial condition.

We have been, and expect to continue to be in the future, significantly dependent on collaboration and supply agreements for the development and sales of Stellar KLH.

In conducting our research and development and commercialization activities, we currently rely, and expect to continue to rely, on collaboration and supply agreements with third parties, such as contract research organizations, commercial partners, universities, governmental agencies and not-for-profit organizations, for strategic, technological, and financial resources. The inability to secure agreements on acceptable terms, the termination of these relationships, changes in our strategy or development plans or those of third parties, or failure to perform by us or third parties who are subject to regulatory, competitive and other risks, under their respective agreements or arrangements with us, would substantially disrupt or delay our research and development and commercialization activities, including potential commercial sales. Any such loss would likely increase our expenses and materially harm our business, financial condition and results of operation.

We have limited marketing, sales and distribution experience and capabilities. We will need to establish sales and marketing capabilities or enter into agreements with third parties to market and sell our products.

We currently have limited experience in the marketing, sales and distribution of KLH products. Depending on market acceptance of our Stellar KLH products, we may need to expand our capabilities. We may not be able to establish such additional capabilities in-house, and then will need to enter into agreements with third parties to successfully perform these tasks. If we contract or make arrangements with third parties for the sales and marketing of our products, our revenues will be dependent on the efforts of these third parties, whose efforts may not be successful. If we market any of our products directly, we must either internally develop or acquire a marketing and sales force, which would require substantial resources and management attention.

We rely on the significant experience and specialized expertise of our Chief Executive Officer and other members of our senior management team, and we will need to hire and retain other highly skilled personnel to maintain and grow our business.

Our ability to be successful in the highly competitive biotechnology and pharmaceutical industries depends in large part upon our ability to attract and retain highly qualified managerial, scientific, medical, sales and other personnel. Our performance is substantially dependent on the research and development and business development expertise of Frank Oakes, our President and Chief Executive Officer, and other executive officers. We do not have employment agreements currently in effect with Mr. Oakes and other executive officers, and they are free to leave their employment with us at any time.

There is little possibility that this dependence will decrease in the near term. The loss of the services of Mr. Oakes, or the increased demands placed on our key executives and personnel by our continued growth, could adversely affect our financial performance and our ability to execute our strategies. Our continued success also depends on our ability to attract and retain qualified team members to meet our future growth needs. We may not be able to attract and retain necessary team members to operate our business.

In addition, our future success depends on our ability to identify, attract, hire, train, retain and motivate highly skilled technical, managerial and research personnel in all areas within our organization. We plan to continue to grow our business and will need to hire additional personnel to support this growth. We believe that there are only a limited number of individuals with the requisite skills to serve in many of our key positions, and we compete for key personnel with other biotechnology companies, as well as universities and research institutions. It is often difficult to hire and retain these persons, and we may be unable to timely replace key persons if they leave or be unable to fill new positions, as they become available, requiring key persons with appropriate experience. If we fail to attract, integrate and retain the necessary personnel, our ability to maintain and grow our business could suffer significantly.

We are subject to the risk of product liability claims, for which we may not have, or be able to obtain, adequate insurance coverage.

The pharmaceutical industry is subject to product liability claims in the event of adverse effects, even in respect to products that have received regulatory approval for commercial sale. Such claims might be made directly by consumers, healthcare providers or by pharmaceutical companies, or others selling or utilizing our Stellar KLH products. Although we currently maintain liability insurance for our products, we may not be able to obtain or maintain sufficient and affordable insurance coverage for all claims that may occur. The cost of any product liability litigation or other proceeding, even if resolved in our favor, could be substantial. In addition, our inability to obtain or maintain sufficient insurance coverage at an acceptable cost or to otherwise protect against potential product liability claims could prevent or inhibit the development and commercial production and sale of our products, which could adversely affect our business, financial condition and results of operations.

Our activities are subject to regulation in the United States and in the foreign jurisdictions in which we operate. Failure to comply with applicable laws and regulations could adversely impact our operations.

Our operations, including our aquaculture and harvesting activities, and our production activities, are subject to regulation at the local, state and federal levels in the United States by a number of regulatory agencies including, but not limited to, the U.S. Food and Drug Administration, the U.S. Environmental Protection Agency, the U.S. Fish and Wildlife Service, the U.S. Secretary of the Navy, The Regional Water Quality Control Board, the California Department of Fish and Wildlife, and similar foreign agencies. In addition to regulations in the United States, we may be subject to a variety of foreign regulations related to research, manufacturing, and the commercial sales and distribution of our products, to the extent we choose to manufacture, sell or distribute any products outside of the United States, such as Mexico. If we are unable to comply with laws and regulations in the United States and elsewhere, our operations could be restricted, or sanctions could be imposed on us, if we are found to not be in compliance with any such regulation.

We may face environmental risks related to handling regulated substances and hazardous materials.

Our research and clinical development activities, as well as the manufacture of materials and products, are subject to federal, state and local laws, rules, regulations and policies governing the use, generation, manufacture, storage, air emission, effluent discharge, handling and disposal of certain materials, biological specimens and wastes. We may be required to incur significant costs to comply with environmental and health and safety regulations in the future. Our research and clinical development, both now and in the future, may involve the controlled use of hazardous materials, including but not limited to certain hazardous chemicals. We cannot completely eliminate the risk of accidental contamination or injury from these materials. In the event of such an occurrence, we could be held liable for any damages that result and any such liability could exceed our resources.

We deal with hazardous materials and must comply with environmental, health and safety laws and regulations, which can be expensive and restrict how we do business and/or give rise to significant liabilities.

As we operate a manufacturing facility, we are subject to various environmental, health and safety laws and regulations, including those governing air emissions, water and wastewater discharges, noise emissions, the use, management and disposal of hazardous materials and wastes, and the cleanup of contaminated sites. The cost of compliance with these laws and regulations could be significant. In the event of a violation of these requirements, including from accidental contamination or injury, we could be held liable for damages exceeding our available financial resources. We could be subject to monetary fines, penalties or third party damage claims as a result of violations of such laws and regulations or noncompliance with environmental permits required at our facility. As an operator of real property and a generator of hazardous materials and wastes, we also could be subject to environmental cleanup liability, in some cases without regard to fault or whether we were aware of the conditions giving rise to such liability. In addition, we may be subject to liability and may be required to comply with new or existing environmental laws regulating pharmaceuticals in the environment. Environmental laws or regulations (or their interpretation) may become more stringent in the future. If any such future revisions require significant changes in our operations, or if we engage in the development and manufacturing of new products or otherwise expand our operations requiring new or different environmental controls, we will have to dedicate additional management resources and incur additional expenses to comply with such laws and regulations.

In the event of an accident, applicable authorities may curtail our use of hazardous materials and interrupt our business operations. In addition, with respect to our manufacturing facility, we may incur substantial costs to comply with environmental regulations and may become subject to the risk of accidental contamination or injury from the use of hazardous materials in our manufacturing process.

Risks Related to Intellectual Property

The inability to protect our intellectual property rights could result in competitive harm to our Company.

Our success and ability to maintain our competitive position depends on our ability to protect our intellectual property, including by obtaining patent protection in the United States and other countries, or through protection of our trade secrets, including unpatented know-how, technology and other proprietary information. When appropriate, we seek to protect our proprietary position by filing patent applications in the United States and other countries. If we are unable to protect our intellectual property, whether by obtaining patents or through trade secret protection, our competitors could develop and commercialize products similar or identical to ours.

We may not have adequate remedies for any infringement or funds to take action against those infringing any of our intellectual property rights, or if our trade secrets otherwise become known or independently developed by competitors. There can be no assurance that any current or future patents held, licensed by or applied for by us will be upheld, if challenged, or that the protections afforded will not be circumvented by others. The patent positions of biotechnology and pharmaceutical companies, which often involve licensing agreements, are frequently uncertain and involve complex legal and factual questions. In addition, the coverage claimed in a patent application can be significantly reduced before the patent is issued. Consequently, our patents, patent applications and licensed rights may not provide protection against competitive technologies or may be held invalid if challenged or could be circumvented. If we enter litigation in regards to our business or to protect or enforce our patents, it may involve substantial expenditures and require significant management attention, even if we ultimately prevail.

The patent position of biotechnology companies is generally highly uncertain. The degree of patent protection we require may be unavailable or severely limited in some cases and may not adequately protect our rights, provide sufficient exclusivity, or preserve our competitive advantage. For example:

Patents have a limited lifespan. In the United States, the natural expiration of a utility patent typically is generally 20 years after it is filed. Various extensions may be available; however, the life of a patent, and the protection it affords, is limited.

In addition, some of our technologies are not covered by any patent application and we rely instead on confidentiality agreements and trade secret law to protect such intellectual property rights. We require all of our employees and consultants to sign confidentiality agreements. The agreements also oblige our employees, and to the extent practicable, our consultants, and advisors, to assign to us ideas, developments, discoveries and inventions made by such persons in connection with their work with us. We cannot be sure that these agreements will maintain confidentiality, will prevent disclosure, or will protect our proprietary information or intellectual property, or that others will not independently develop substantially equivalent proprietary information or intellectual property.

The failure of our patents, patent applications, applicable intellectual property law or our confidentiality agreements to protect our intellectual property and other proprietary information, including our trade secrets, could have a material adverse effect on our competitive advantages and on our operations and financial position.

Changes in patent law could diminish the value of patents in general, thereby impairing our ability to protect our products and our technologies. There are numerous recent changes to the U.S. patent laws and proposed changes to the rules of the United States Patent and Trademark Office (USPTO) that may have a significant impact on our ability to obtain and enforce intellectual property rights. In particular, the Leahy-Smith America Invents Act (Leahy-Smith Act) was adopted in September 2011. The Leahy-Smith Act includes a number of significant changes to U.S. patent law, including provisions that affect the way patent applications will be prosecuted and may also affect patent litigation. Under the Leahy-Smith Act, the United States transitioned from a “first-to-invent” system to a “first-inventor-to-file” system for patent applications filed on or after March 16, 2013. With respect to patent applications filed on or after March 16, 2013, if we are the first to invent but not the first to file a patent application, we may not be able to fully protect our intellectual property rights and may be found to have violated the intellectual property rights of others if we continue to operate in the absence of a patent issued to us. Many of the substantive changes to patent law associated with the Leahy-Smith Act have recently become effective. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of any patents that issue, all of which could have a material adverse effect on our business and financial condition.

In addition, patent reform legislation may pass in the future that could lead to additional uncertainties and increased costs surrounding the prosecution, enforcement, and defense of patent applications and any patents we may obtain. Furthermore, the U.S. Supreme Court and the U.S. Court of Appeals for the Federal Circuit have made, and will likely continue to make, changes in how the patent laws of the United States are interpreted. Similarly, foreign courts have made, and will likely continue to make, changes in how the patent laws in their respective jurisdictions are interpreted. We cannot predict future changes in the interpretation of patent laws or changes to patent laws that might be enacted into law by United States and foreign legislative bodies. Those changes may materially affect our patents and patent applications or any patents we may obtain and our ability to obtain and enforce or defend additional patent protection in the future.

We may not be able to adequately protect our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on our products and technologies in all countries throughout the world would be prohibitively expensive. We have never, and may never, seek to enforce our U.S. patent. The requirements for patentability may differ in certain countries, particularly developing countries, and the breadth of patent claims allowed can be inconsistent. In addition, the laws of some foreign countries may not protect our intellectual property rights to the same extent as laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we have patent protection, but enforcement on infringing activities is inadequate.

We seek to protect our proprietary position by, among other methods, filing, when possible, U.S. and foreign patent applications relating to our technology, inventions and improvements that are important to our business. We have obtained patent protection for our non-lethal extraction methods of hemocyanin in the United States and other countries. We also rely on trade secrets, know-how, continuing technological innovation, and in-licensing opportunities to develop and maintain our proprietary position.

We plan to file other international patent applications directed to patentable features of our products and technologies from time to time. If patent rights are obtained in foreign jurisdictions, proceedings to enforce such rights could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly, could put our pending patent applications at risk of not issuing, and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Thus, we may not be able to stop a competitor from marketing and selling in foreign countries products that are the same as or similar to our product.

We may become involved in lawsuits to protect or enforce our patents and patent applications, any patents that may be issued to us or other intellectual property, which could be expensive, time consuming and unsuccessful.

Competitors may infringe our patents or patent applications, or other of our intellectual property. To counter infringement or unauthorized use, we may be required to file infringement or misappropriation claims, which can be expensive and time consuming. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their patents or claiming that our patents are invalid or unenforceable. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, non-enablement or lack of statutory subject matter. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant material information from the USPTO, or made a materially misleading statement, during prosecution. Third parties may also raise similar validity claims before the USPTO in post-grant proceedings such as ex parte reexaminations, inter partes review, or post-grant review, or oppositions or similar proceedings outside the United States, in parallel with litigation or even outside the context of litigation. The outcome following legal assertions of invalidity and unenforceability is unpredictable. We cannot be certain that there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. For any patents and patent applications we may license, we may have limited or no right to participate in the defense of any such patents against challenge by a third party. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of any future patent protection on our products. Such a loss of patent protection could harm our business. In addition, in a patent infringement proceeding, a court may decide that our patent applications or patents, if issued, are invalid or unenforceable, in whole or in part, construe the patent’s claims narrowly, or refuse to stop the other party from using the technology at issue on the grounds that our patent applications do not cover the technology. An adverse result in any litigation proceeding could put one or more of our patents at risk of being invalidated or interpreted narrowly.

Our trade secrets are difficult to protect and misappropriation could reduce the market for our products.

We may not be able to obtain adequate remedies for the unauthorized use or disclosure of our proprietary information, including our trade secrets. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time consuming, and the outcome is unpredictable. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position could be harmed.

Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain and could have a material adverse effect on the success of our business.

Our success depends, in part, on our ability to operate without infringing the patents and other proprietary intellectual property rights of third parties. This is generally referred to as having the “freedom to operate.” The biotechnology and pharmaceutical industries are characterized by extensive litigation regarding patents and other intellectual property rights. The defense and prosecution of intellectual property claims, interference proceedings and related legal and administrative proceedings, both in the United States and internationally, involve complex legal and factual questions. As a result, such proceedings are lengthy, costly and time-consuming, and their outcome is highly uncertain. We may become involved in protracted and expensive litigation in order to determine the enforceability, scope and validity of the proprietary rights of others, or to determine whether we have the freedom to operate with respect to the intellectual property rights of others.

Patent applications in the United States are, in most cases, maintained in secrecy until approximately 18 months after the patent application is filed. The publication of discoveries in the scientific or patent literature frequently occurs substantially later than the date on which the underlying discoveries were made. Therefore, patent applications relating to a product or method similar to ours may have already been filed by others without our knowledge. In the event that a third party has also filed a patent application covering our products, methods or other claims, we may have to participate in an adversarial proceeding, such as an interference or derivation proceeding in the USPTO or similar proceedings in other countries, to determine the priority of invention. In the event an infringement claim is brought against us, we may be required to pay substantial legal fees and other expenses to defend such a claim and, if we are unsuccessful in defending the claim, we may be subject to injunctions or damage awards.

In the future, the USPTO or a foreign patent office may grant patent rights to our claims to third parties. Subject to the issuance of these future patents, the claims of which will be unknown until issued, we may need to obtain a license or sublicense to these rights in order to have the appropriate freedom to further use, develop or commercialize such products or methods. Any required licenses may not be available to us on acceptable terms, if at all. If it is determined that we have infringed an issued patent and do not have the freedom to operate, we could be subject to injunctions, and compelled to pay significant damages, including punitive damages, which could harm our business.

We may become involved in lawsuits to protect or enforce our patents and patent applications, any patents that may be issued to us or other intellectual property, which could be expensive, time consuming and unsuccessful.

If we become involved in any patent litigation or other legal proceedings, we could incur substantial expense, and the efforts of our technical and management personnel could be significantly diverted. A negative outcome of such litigation or proceedings may expose us to the loss of our proprietary position or to significant liabilities, or require us to seek licenses that may not be available from third parties on commercially acceptable terms, if at all. We may be restricted or prevented from using or developing methods, or manufacturing and selling our products in the event of an adverse determination in a judicial or an administrative proceeding, or if we fail to obtain necessary licenses. Further, even if we are successful in defending against claims of infringement, such litigation could be burdensome and costly, and divert management’s attention away from executing our business plan.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of third parties.

Certain of our employees were previously employed at other biotechnology or pharmaceutical companies. We may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise improperly used or disclosed confidential information of these third parties or our employees’ former employers. We may also be subject to claims that former employees, consultants, independent contractors or other third parties have an ownership interest in our patents or other intellectual property. Litigation may be necessary to defend against these and other claims challenging our right to and use of confidential and proprietary information. If we fail in defending any such claims, we may lose our rights to such information, in addition to paying monetary damages. Such an outcome could have a material adverse effect on our business. Even if we are successful in defending against these claims, litigation could result in substantial cost and be a distraction to our management and employees.

Risks Related to an Emerging Growth Company

We are an “emerging growth company” under the JOBS Act of 2012 and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our common shares less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (JOBS Act), and as a result, we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies.” We may take advantage of these reporting exemptions until we are no longer an “emerging growth company.” We will remain an “emerging growth company” until the earlier of: (i) the last day of the fiscal year (a) following the fifth anniversary of the date of our first sale of common equity securities pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “Securities Act”), (b) in which we have more than $1.07 billion in annual revenues ($1.0 billion threshold adjusted for inflation effective April 2017), or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common shares that is held by non-affiliates exceeded $700 million as of the prior March 31st and (ii) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period. While we became a reporting company following the effectiveness of our Form 20-F, filed with the Securities and Exchange Commission on February 3, 2012, our first sale of common equity securities pursuant to an effective registration statement under the Securities Act of 1933 was July 6, 2016. We may choose to take advantage of some but not all of these reduced reporting burdens.

For so long as we remain an emerging growth company, we will not be required to:

In addition, Section 107 of the JOBS Act also provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected not to take advantage of the extended transition period for complying with new or revised accounting standards.

If we take advantage of any of these reduced reporting burdens in future filings, the information that we provide our security holders may be different than information such security holders might receive from other public companies in which they hold equity interests. We cannot predict if investors will find our common shares less attractive because we may rely on these exemptions. If some investors find our common shares less attractive as a result, there may be a less active trading market for our common shares and our share price may be more volatile.

SPECIALCAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
