PART I

Item 1. | Business

General

Nanophase Technologies Corporation (“Nanophase” or the “Company”, including “we”, “our” or “us”) is an advanced materials and applications developer and commercial manufacturer with an integrated family of materials technologies. We produce engineered nano and sub-micron materials for use in a variety of diverse markets: personal care including sunscreens, architectural coatings, industrial coating applications, abrasion-resistant additives, plastics additives, medical diagnostics, energy and a variety of surface finishing technologies (polishing) applications, including optics.

While our origin is based on the creation of nanoscale metal oxide products, we have expanded our offerings to include larger but still sub-micron materials. We have developed techniques for managing attributes including particle size, shape, surface coatings, and other valuable aspects of the material. Our focus is on customer need where we believe we have an advantage, as opposed to finding uses for one particular technology. Additionally, as the format of delivery is important to customers, we have developed proprietary capabilities for dispersing our materials into both aqueous (water-based) and solvent-based liquid media. These capabilities allow us to better integrate with the customer’s need and application.

We target markets in which we believe practical solutions may be found using our products. We work closely with current and potential customers in these target markets to identify their material and performance requirements and market our materials to various end-use applications manufacturers. Recently developed technologies have made certain new products possible and opened potential new markets. We expect growth in end-user (manufacturing customers, including customers of our customers) adoption in 2015 and beyond. Our initiatives in targeted market areas are progressing at differing rates of speed, but we have been broadly moving through testing and development cycles, and in a number of cases believe we are approaching first revenue or next stage revenue with particular customers in the industries referenced above. During 2014 we developed new solutions in surface finishing technologies (polishing) and energy-management areas that have been taken to potential customers, with commercial order flow accelerating in the former and significant commercial testing activities happening in the latter. We believe that successful introduction of our materials with manufacturers may lead to follow-on orders for other materials in their applications. Although our primary strategic focus has been the North American market, we currently sell material to customers overseas and have been working to expand our reach within foreign markets. The Company was incorporated in Illinois on November 25, 1989, and became a Delaware corporation during November 1997. Our common stock trades on the OTCQB marketplace under the symbol NANX.

We have created a leading commercial approach to the application of our integrated materials technologies designed to deliver an optimal engineered solution for a target market or specific customer application. With respect to our products, we have complete capability from application development and laboratory samples through pilot production and, finally, commercial production currently at rates as high as hundreds of metric tons per year for individual products. We have development and application laboratories and manufacturing capacity in two locations in the Chicago area. Our manufacturing is based on Lean Six Sigma discipline and is certified to ISO 9001, American National Standard, Quality Management System Requirements; ISO 14001, American National Standard, Environmental Management System Requirements; and is compliant with current Good Manufacturing Practices (“cGMP”) for products under U.S. Food and Drug Administration (“FDA”) regulation.

We have undergone a strategic shift during recent years toward penetrating key markets via interactive applications development with end-use customers in these markets. We also supply both

nanoscale and larger materials, based on market requirement. We believe this strategy leverages the applications development expertise we have cultivated over the last several years and best positions us to build direct sales to end-use customers, in addition to translating these advantages through our market partners.

Nanomaterials

Nanomaterials are generally comprised of particles (nanoparticles) that are less than 100 nanometers in diameter and these nanoparticles have a wide range of unique properties owing to their very small size. A nanometer is one-billionth of a meter, or about 100,000 times smaller in size than the width of a human hair.

Nanotechnology involves manipulating the properties of materials, made up of basic elements or combinations thereof, at the 100-nanometer level or below. At this scale, the relatively small number of constituent atoms, the large proportion of these atoms on surfaces, and their confined dimensions lead materials to exhibit unique properties that can be used in many applications to benefit performance.

Nanomaterials are an important and enabling part of the diverse field of nanotechnology and are the building blocks of our nanotechnology products. The ultimate performance and value of Nanophase’s products in a given application is a function of nanoparticle composition, size, shape, structure, surface chemistry and coating and dispersion potential. Our technologies for engineering and manufacturing nanomaterials, and our understanding of how to make nanomaterials exhibit desirable performance characteristics in various media, result in commercial nanomaterials solutions that we believe offer superior performance in many applications.

Nanomaterials have applications in diverse global markets where they are incorporated into a process, such as optics polishing, or a product, such as an industrial coating to prevent degradation or aid in application, or significantly improve wear resistance, or promote/hamper particular chemical reactions within respective systems. Multiple markets exist for our products since nanomaterials offer advantages in many applications, such as improved properties and performance, longer wear or product life, lower overall product cost, or in the development of new products or processes.

Most of the raw materials we use are commercially available. In some cases, we rely on sole-source processors of materials that utilize an array of worldwide sources for the raw materials that they process to our specifications. However, in certain cases we deal with very limited supply of certain elements, such as those classified as “Rare Earth” elements- specifically cerium oxide for use in surface finishing technologies (polishing) applications. On a worldwide basis, the vast majority of these elements are sourced from China. Due to severe export limitations imposed by China from 2010 through 2012, the supply of all Rare Earth elements was drastically reduced from previous levels. While prices and availability improved by the end of 2012, the cost remains higher than it was prior to 2010. In addition, this market dynamic created significant concerns, globally, pertaining to the availability and cost of using these materials, which continue to pose customer acceptance risk for elements of our polishing business going forward.

Our Technologies

We have created an integrated platform of commercial nanomaterial technologies that are patented, patent-pending or proprietary. These technologies are designed to deliver a nanomaterial solution for a targeted market or a specific customer application. Our platform provides flexibility and capability to engineer nanomaterials that meet a customer’s performance requirements and delivers our nanomaterial solutions in a readily usable format. Our technologies are scalable and robust, having produced several hundred metric tons annually.

Our nanomaterials platform includes two distinct manufacturing processes (PVS — Plasma Vapor Synthesis and NAS - NanoArc® Synthesis) to make nanomaterials or nanoparticles. These technologies

4

##### Table of Contents

allow us to control critical nanomaterial properties (composition, size, shape, structure, surface chemistry) and engineer these attributes to meet specific application performance. Compared to other well-developed known nanoparticle processes, our plasma-produced particles are produced as nonporous, dense, discrete single crystals, which we believe possess a unique set of bulk and surface properties.

Perhaps of greater importance, we have developed proprietary technology to disperse nanoparticles in both aqueous (water-based) and several organic solvent systems. These dispersions are stable at high weight loading (typically 18-55% by weight). These aspects provide distinct market advantages. Dispersed nanomaterials are desired by many customers for use in their processes or products because of the ease of incorporation. As examples, dispersed nanomaterials are used in architectural coatings, industrial cleaning solutions, industrial coatings, plastic additives and optical and semiconductor polishing. This integration flexibility allows us to serve more customers and serve them better, and is critical to our role as a solutions provider, not simply that of a materials provider.

We have also developed patented and proprietary technology to coat or surface treat nanoparticles to further engineer surface chemistry by two main processes. In many applications, such as sunscreens, this technology is vital to ensure formulation compatibility and, in some cases, optimal application performance. We deliver hundreds of metric tons of surface engineered nanoparticles to our customers annually, including coated nanomaterials that are used by major global consumer products companies for sunscreens and personal care products.

As markets continue to develop and grow, we believe that customers’ preferred delivery formats will often be dispersed and/or coated nanomaterials. We believe we are well-positioned with our platform of integrated commercial nanomaterial technologies to respond to this demand. We plan to maintain and advance our intellectual property and technologies to remain competitive in the fields of nanomaterials development, applications development and commercialization.

We have used our expertise in nanoscale materials to develop larger sub-micron particle–based products that are not considered “nano” in various applications. Controlling aspects including particle size and shape, as well as surface chemistries, allow us to provide superior materials to the marketplace in various formats, both at the nano level and above.

We have steadily expanded our ability to commercially utilize and deliver our technologies. Through large-scale manufacturing of nanomaterials utilized in the manufacture of consumer sunscreen and personal care products and architectural coatings, we have developed production expertise that has allowed us to improve processes relating to those nanomaterials as well as processes relating to other nanomaterials. This experience has translated into additional know-how, intellectual property and advances in the technologies and manufacturing processes that reduce variable manufacturing costs and improve gross margins.

Marketing and Distribution Methods

We focus our marketing strategy on differentiated solutions that create superior value for our customers. This customer-focused strategy means we are not solely dependent upon the efforts of a distributor for future sales growth. We have found many cases where our ability to effectively integrate nanomaterials into a customer’s specific chemistry is critical to presenting an effective solution. Given this reality, we launched a “customer direct” business model during 2009 for those markets that are not conducive to an intermediary. In these markets, we interact with customers directly rather than through intermediaries, demonstrating the benefits of our solutions in their products. Our deep market knowledge of certain markets and applications has allowed us to understand customer needs and our products’ value proposition, and adapt our offerings accordingly. This knowledge, combined with our applications development expertise, supports leveraging our development efforts by marketing and selling our solutions to multiple customers within each market. We work closely with each customer to develop a material solution for that entity’s specific application(s), but we find that as we develop greater applications development expertise in a given area, specific applications development often becomes a

##### Table of Contents

routine process within Nanophase. This is where we believe our future customers will perceive the greatest value in working with us, and where we will be able to leverage our product development efforts into multiple revenue generating customer solutions. Surface finishing technologies (polishing) is an example of such a market.

We see this customer-focused marketing approach increasing our probability of success in many markets, allowing us to use an integrated platform of material technologies and typically reducing the total time-to-market. The more our applications development scientists and sales team work directly with customers to develop nanomaterial solutions, the more quickly and successfully we believe we will be able to grow sales.

In addition to serving customers in diverse markets and geographic locations, we will continue to devote significant resources to maintaining and growing our relationship with BASF Corporation (“BASF”), our largest customer in the personal care market. This has been a successful relationship that we expect will contribute to our future growth. BASF, which describes itself as the world’s leading chemical company with revenue in excess of $100 billion, is a global leader in the personal care market with recognized brands, significant revenues and sales reach. We have a long-term exclusive relationship with BASF, primarily to provide our zinc oxide-based products to be used in personal care with sunscreens and daily wear products being the dominant applications.

In addition to the personal care applications described above, our products are used in a variety of other applications, including architectural coatings, polishing applications (including optical glass and CMP), plastics additives, medical diagnostics, textiles and graphic arts, energy control applications, and others. Recent activities have expanded our presence in the polishing / surface finishing applications space, and 2013 saw us develop two solutions for the energy sector (consumer) that were taken to market leaders for evaluation during 2014. Our efforts in these areas of recent activity will continue in 2015, and we expect a combination of these new solutions in the surface finishing (polishing) and energy sector (consumer) areas to yield significant incremental revenue going forward.

Because our technology can be applied to a wide variety of applications, we focus our efforts on only a handful of applications to gain a depth of knowledge and leverage our learning curve. If we find a unique application outside of our core markets that does not require significant development resources then we may pursue it as “opportunistic” business. We believe this focused approach will contribute to a higher success rate for related opportunities than we would experience by pursuing more opportunities simultaneously.

Technology and Engineering

Our efforts in research and development, process engineering and advanced engineering groups are focused in three major areas: 1) application development for our products; 2) creating or obtaining additional core material technologies and/or materials that have the capability to serve multiple markets; and 3) continuing to improve our core technologies to improve manufacturing operations and reduce costs.

Most of our research and development is directly related to applications development. We endeavor to either meet specific customer needs or to develop applications solutions to address unmet needs in a particular market where we believe our materials will offer a distinct performance advantage. We believe that aggressively pursuing applications in targeted areas will help us compete as a technical and commercial innovator using our materials expertise, and more importantly, become perceived as a solutions provider by our customers and not simply as another materials supplier.

Our total research and development expense, which includes all expenses relating to our technology and advanced engineering groups, during the years ended December 31, 2014 and 2013, was $1.3 million and $1.7 million, respectively. This represents our share of these expenses only and does not take into account amounts spent by any of our customers in support of new product development. Our

6

##### Table of Contents

future success will depend in large part upon our ability to develop products which bring a high degree of value to our customers’ products. Through the three-year period ended December 31, 2014, we had cumulative research and development expenses of approximately $5 million and cumulative expenditures on equipment and leasehold improvements of approximately $0.4 million.

Manufacturing Operations

We have manufacturing capacity based in two locations in the Chicago area. At each of these facilities, we are able to develop and supply nanomaterials in quantities ranging from grams to metric tons. Our facilities are certified to ISO 9001:2008 international standards and are cGMP compliant for applicable bulk pharmaceutical manufacturing. We are also in the process of registering some of the chemicals we ship to customers in Europe pursuant to the European Chemical Agency’s regulations issued to date pertaining to Registration Evaluation and Authorization of Chemicals (“REACH”). We have registered Zinc Oxide under REACH and filed preliminary registrations for other materials. Our facilities are also certified to the international standard for environmental management, ISO 14001:2004.

Our operations employ a cellular, team-based manufacturing approach, where workers operate in work “cells,” under a lean manufacturing environment to continuously advance and improve production capabilities. We have also developed a highly flexible workforce that has been cross-trained to allow it to be employed broadly across our manufacturing processes. Our manufacturing approach and targeted engineering actions have resulted in continuing process innovations and improvements that have reduced the variable manufacturing cost significantly over the past several years.

We are committed to a lean manufacturing approach, to the extent possible given a certain measure of irregular demand, where we are able to reduce excess labor and manage the lowest practical inventory and supply levels in order to minimize working capital demands. This approach complements two of our major operational goals - (1) to increase output without adding unnecessarily to existing equipment and (2) to continually reduce production costs while consistently producing high quality products.

Intellectual Property and Proprietary Rights

We rely on a combination of patent, trademark, copyright, trade secret and other intellectual property laws, nondisclosure agreements and other protective measures to protect our intellectual property. In addition to obtaining patent and trademarks based on our inventions and products, we may also license certain third-party patents from time-to-time to expand our technology base.

As of the date of this filing, we own 11 U.S. patents and 2 pending U.S. patent applications. We also own 35 foreign patents and patent applications consisting of 30 issued or allowed foreign patents and 5 pending foreign patent applications. All of the pending and owned foreign patents are counterparts to domestic filings covering our platform of nanotechnologies. Our oldest issued patents began to expire during 2013. We do not believe that the expiration of these patents will have a material impact on our business or financial condition.

Competition

Within each of our targeted markets and product applications, we face potential competition from advanced materials and chemical companies, and suppliers of traditional materials. In many markets, the actual or potential competitors are larger and more diversified than we are; however, we believe we focus in market segments and opportunities where our materials and related technologies are superior to those

7

##### Table of Contents

of our competitors, often due to our ability to produce highly engineered products to meet specific performance requirements and develop nanomaterial solutions for customers’ specific applications.

With respect to traditional suppliers, we may compete against lower priced traditional materials for certain customer applications. In some product or process applications the benefits of using nanomaterials do not always justify a process change or outweigh their frequently higher costs.

With respect to larger producers of nanomaterials, while many of these producers do not currently offer directly competitive products, these companies may have greater financial and technical resources, larger research and development staffs, and greater manufacturing and marketing capabilities, and could compete directly against us. In addition, the number of development-stage companies involved in nanocrystalline materials continues to grow on a global basis, posing increasing competitive risks. Many of these companies are associated with university or national laboratories and use chemical and physical methods to produce nanocrystalline materials. We believe that most of these companies are engaged primarily in funded research and not commercial production; however, they may represent competitive risks in the future. Some development-stage companies, especially in other countries, receive significant government assistance or enjoy other benefits due to their location. We anticipate that foreign competition will play a greater role in the nanomaterials arena in the future, something we are increasingly seeing today, albeit indirectly.

We believe that our nanomaterial technologies and manufacturing platforms are strong. We believe we are well-positioned with our platform of integrated commercial nanomaterial technologies and track record of technology improvement and evolution.

Governmental Regulations, Including Climate Change

The manufacture and use of certain of the products that contain our nanocrystalline materials are subject to governmental regulations. As a result, we are required to adhere to the cGMP requirements of the FDA and similar regulations that include testing, control and documentation requirements enforced by periodic inspections. We are also in the process of registering some of the chemicals we ship to customers in Europe in compliance with the European Chemical Agency’s regulations issued to date pertaining to REACH (to date, we have registered Zinc Oxide under REACH and filed preliminary registrations for other materials).

We are committed to environmental health and safety (“EH&S”). We believe we comply with all applicable exposure limit standards issued by OSHA. Because nanotechnology remains an emerging and evolving science, there are no currently accepted standards, measurements or personal protective equipment available that are specific to nanoparticle safety. Accordingly, we rely on general chemical safety and process safety practices to identify safe personal protective equipment and appropriate handling protocols. We believe that we have taken a leadership position on EH&S in our operations and have internal and external review and monitoring of our practices.

In addition, our facilities and operations are subject to the plant and laboratory safety requirements of various environmental and occupational safety and health laws. We believe we are in compliance with all such laws and regulations, and to date, those regulations have not materially restricted or impeded operations. Further, we believe our processes to be highly efficient, generating very low levels of waste and emissions. For this reason, we do not view issues surrounding climate change and any currently foreseeable related regulations as materially impacting our business and financial statements, beyond any inestimable impact on the macro-economic environment.

We have taken a responsible, proactive approach to EH&S by implementing appropriate procedures and processes to have our facilities certified to ISO 14001, American National Standard, Environmental Management System Requirements. We are also involved with leading industry groups that are defining nanomaterial standards and protocols. These currently include the ASTM International

8

##### Table of Contents

Committee on Nanotechnology, Nanoscale Materials Stewardship Program under the Toxic Substances Control Act, and the US TAG to ISO TC 229 Nanotechnology committee managed by the American National Standards Institute committee (ANSI). We also participate in FDA reviews relative to cosmetic applications. We have a full-time, advanced degreed professional who spends a significant amount of time managing governmental regulation compliance and EH&S. We believe that our Company has an exemplary safety record.

Employees

On December 31, 2014, we had a total of 39 full-time employees, 5 of whom hold advanced degrees. We have no collective bargaining agreements and believe that we have a strong relationship with our employees.

Backlog

We do not believe that a backlog as of any particular date is indicative of future results. Our sales are primarily pursuant to purchase orders for delivery of our nanomaterials. We have some agreements that give customers the right to purchase a specific quantity of nanomaterials during a specified time period. These agreements, however, do not obligate the customers to purchase any minimum quantity of such nanomaterials. The quantities actually purchased by the customer, as well as the shipment schedules, are frequently revised during the agreement term to reflect changes in the customer’s needs. For these reasons we do not believe that such agreements are meaningful for determining backlog amounts.

Business Segment and Geographical Information

Our operations comprise a single business segment and all of our long-lived assets are located within the United States. See Note 13 to the accompanying Financial Statements for additional information.

Key Customers

A limited number of key customers account for a substantial portion of our commercial revenue. In particular, revenue from three customers - our largest customer in personal care applications (BASF), our medical diagnostics application customer, and our largest coatings customer - constituted approximately 72%, 6% and 5%, respectively, of our 2014 total revenue. Many of our customers are significantly larger than we are and, therefore, may be able to exert a high degree of influence over us. While our agreements with BASF are long-term agreements, they may be terminated by BASF under certain circumstances with reasonable notice and do not provide any guarantees that BASF will buy our products. The loss of one of our largest customers or the failure to attract new customers could have a material adverse effect on our business, results of operations and financial condition. Due to the high concentration of sales to a limited number of customers, we have aggressively pursued new customers through our customer direct business model. To the extent we are successful in adding a large number of customers through this model and maintaining or expanding our existing partners, we believe we will be able to best manage the risks associated with customer concentration.

Forward-Looking Statements

We want to provide investors with more meaningful and useful information. As a result, this Annual Report on Form 10-K (the “Form 10-K”) contains certain “forward-looking statements”, as defined in Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

We have a history of losses that may continue in the future.

We have incurred net losses in each year since our inception, with net losses of $1.7 million in 2014 and $2.5 million in 2013. As of December 31, 2014, we had an accumulated deficit of approximately $92 million and may incur a loss on an annual basis during 2015. We believe that our business depends, among other things, on our ability to significantly increase revenue. If revenue fails to grow at anticipated rates or if operating expenses increase without a commensurate increase in revenue, or if we fail to adjust operating expense levels accordingly, then the imbalance between revenue and operating expenses will negatively impact our cash balances and our ability to achieve profitability in future periods.

We depend on a few major customers for a high percentage of our sales, and the loss of orders from a significant customer could cause a decline in revenue and/or increases in the level of losses incurred.

Sales to our customers are executed pursuant to purchase orders and long-term supply contracts; however, customers can cease doing business with us at any time with limited advance notice. It is possible that a significant portion of our future sales may remain concentrated within a limited number of strategic customers. We may not be able to retain our strategic customers, such customers may cancel or reschedule orders, or in the event of canceled orders, such orders may not be replaced by other sales or by sales that are on as favorable terms. In addition, sales to any particular customer may fluctuate significantly from quarter to quarter, which could affect our ability to achieve anticipated revenues on a quarterly basis.

Sales to our three largest customers accounted for 72%, 6% and 5%, respectively, of our total revenue in 2014 and sales to these same customers accounted for 72%, 3% and 6%, respectively, of our total revenue in 2013.

We plan to expand both our marketing and business development efforts and our production efficiency in order to address the issues of our dependence upon a limited amount of customers, enhancement of gross profit and operating cash flows, and the achievement of profitability. Given the nature of our products, and the fact that markets for them are not yet fully developed, it is difficult to accurately predict when additional large customers will materialize. Going forward, our margins, as a percentage of revenue, will be dependent upon revenue mix, revenue volume, raw materials pricing, and our ability to continue to cut costs. The extent of the growth in revenue volume and the related gross profit that this revenue generates will be the main drivers in generating positive operating cash flows and, ultimately, net income.

Any downturn in the product markets served by us would harm our business.

A majority of our products are incorporated into products such as personal care applications including sunscreens, architectural coatings, surface finishing technologies (polishing), and to a lesser extent, medical diagnostics, abrasion-resistant coatings and other products. These markets have from time to time experienced cyclical, depressed business conditions, often in connection with, or in anticipation of, a decline in general economic conditions. These industry downturns often result in reduced product demand and declining average selling prices. Our business would be harmed by a continuation of any downturn and/or any future downturns in the markets that we serve.

Our products often have long adoption cycles, which could make it difficult to achieve market acceptance and makes it difficult to forecast revenues.

Due to their often novel characteristics and potential unfamiliarity with them that exists in the marketplace, our nanomaterials may require longer adoption cycles than existing materials technologies, to the point that adoption cycles typically require one to five years. Our nanomaterials have to receive appropriate attention within any potential customer’s organization, and then they must be tested to prove a performance advantage over existing materials, typically on a systems-cost basis. Once we have proven initial commercial viability, pilot scale production runs are typically required and completed by the customer, followed by further testing. Once production-level commercial viability is established, then our nanomaterials can be introduced, often to a downstream marketplace that needs to be familiarized with them. If we are unable to demonstrate to our potential customers the performance advantages and economic value of our nanomaterials over existing and competing materials and technologies, we will be unable to generate significant sales. Our long adoption cycle makes it difficult to predict when sales will occur.

We frequently depend on collaborative development relationships with our customers. If we are unable to initiate or sustain such collaborative relationships or if the terms of these relationships limit the distribution of our products, then we may be unable to successfully develop, manufacture or market our current and future nanomaterials or applications.

We have established, and will continue to pursue, strategic relationships with many of our customers and do not have a substantial direct sales force or an established distribution network (other than distribution arrangements for research samples). Through these relationships, we seek to develop new applications for our nanomaterials and share development and manufacturing resources. We also seek to coordinate the development, manufacture and marketing of our nanomaterials products, particularly as a result of our selling additives that must be integrated into complete formulations by the customer. Future success will depend, in part, on our continued relationships with these customers and our ability to enter into similar strategic relationships with other customers. Our customers may not continue in these collaborative development relationships, may not devote sufficient resources to the development or sale of our materials or may enter into strategic development relationships with our competitors. These customers may also require a share of control of these collaborative programs. While less prevalent than in the past, some of our agreements with these customers limit our ability to license our technology to others and/or limit our ability to engage in certain product development or marketing activities with others. These relationships generally can be terminated unilaterally by customers.

If we are unable to initiate or sustain such collaborative relationships or if the terms of these relationships materially limit our access to distribution channels for our products, then we may be unable to successfully develop, manufacture or market our current and future nanomaterials or applications.

If commodity metal prices increase at such a rate that we are unable to recover lost margins on a timely basis or that our products became uncompetitive in their current marketplaces, our financial and liquidity position and results of operations would be substantially harmed.

Many of our significant raw materials come from commodity metal markets that may be subject to rapid price increases. While we generally are able to pass a significant portion of commodity “price-related” increases on to our customers, it is possible that, given our limited customer base and the limited control we have over it, commodity metal prices could increase at such a rate that could hinder our ability to recover lost margins from our customers. It is also possible that such drastic cost increases could render some of our materials uncompetitive in their current marketplaces when considered relative to other materials on a cost benefit basis. If either of these potential results occurred, our financial and liquidity position and results of operations would be substantially harmed.

From 2010-2012, the availability of one of the materials we use, cerium oxide, a “Rare Earth” material, was constrained by a change in Chinese export policy, causing a dramatic increase in material cost. While prices and availability improved by the end of 2012, the cost of this material remains higher than it was prior to 2010. While cerium oxide continues to be used for many applications, polishing applications in our case, customers are more inclined to look for alternative solutions today as they consider the supply (including cost) risk of this material. Failure of customers to either adopt solutions utilizing cerium oxide or continue to use solutions containing cerium oxide could harm one of our business areas, and thus negatively impact our financial and liquidity position and results of operations.

Protection of our intellectual property is limited and uncertain.

Our intellectual property is important to our business. We seek to protect our intellectual property through patent, trademark, copyright, and trade secret protection and confidentiality or license agreements with our employees, customers, suppliers and others. Our means of protecting our intellectual property rights in the United States or abroad may not be adequate and others, including our competitors, may use our proprietary technology without our consent. We may not receive the necessary patent protection for any applications pending with the U.S. Patent and Trademark Office (“USPTO”) and any of the patents

12

##### Table of Contents

that we currently own or license may not be sufficient to keep competitors from using our materials or processes. In addition, patents that we currently own or license may not be held valid if subsequently challenged by others and others may claim rights in the patents and other proprietary technology that we own or license. Additionally, others may have already developed or may subsequently develop similar products or technologies without violating any of our proprietary rights. If we fail to obtain or maintain patent protection or preserve our trade secrets, we may be unable to effectively compete against others offering similar products and services. In addition, if we fail to operate without infringing the proprietary rights of others or lose any license to technology that we currently have or will acquire in the future, we may be unable to continue making the products that we currently make.

Moreover, at times, attempts may be made to challenge the prior issuance of our patents. Furthermore, litigation may be necessary to enforce our intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others, or to defend against claims of infringement or invalidity. Such litigation could result in substantial costs and diversion of resources and could harm our business, operating results and financial condition. Such litigation might occur with parties that have substantially greater resources, and thus more capability to engage and continue litigation. In addition, if others assert that our technology infringes their intellectual property rights, resolving the dispute could divert our management team and financial resources.

Due to the expanding length of time required in order to obtain a patent, and the inherent ongoing risks of the protections truly provided by any patent, we made a decision during 2008 that we could no longer place a value on these intangible assets. In the future, we may license certain of our intellectual property, such as trademarks, to third parties. While we would attempt to ensure that any licensees maintain the quality and value of our brand, these licenses might diminish this quality and value.

If a catastrophe strikes either of our manufacturing facilities or if we were to lose our lease for either facility due to non-renewal or other unforeseen events, we may be unable to manufacture our materials to meet customers’ demands.

Our manufacturing facilities are located near Chicago—in Romeoville and Burr Ridge, Illinois. These facilities and some of our manufacturing and testing equipment would be difficult to replace in a timely manner. Therefore, any material disruption at one of our facilities due to a natural or man-made disaster or a loss of lease due to non-renewal or other unforeseen events could have a material adverse effect on our ability to manufacture products to meet customers’ demands. While we maintain property insurance, this insurance may not adequately compensate us for all losses that we may incur in the event of a material interruption in our business.

If we are unable to expand our production capabilities to meet unexpected demand, we may be unable to manage our growth and our business would suffer.

Our success will depend, in part, on our ability to manufacture nanomaterials in significant quantities, with consistent quality and in an efficient and timely manner. We expect to be able to expand our current facilities or obtain additional facilities in the future, and outsource production aspects as necessary, available and appropriate, in order to respond to unexpected demand for existing materials or for new materials that we do not currently make in quantity. Such unplanned demand, if it resulted in rapid expansion, could create a situation where growth could become difficult to manage, which could cause us to lose potential revenue.

Our industry is experiencing rapid changes in technology. If we are unable to keep pace with these changes, our business may not grow.

Rapid changes have occurred, and are likely to continue to occur, in the development of advanced materials and processes. Our success will depend, in large part, upon our ability to keep pace with advanced materials technologies, industry standards and market trends and to develop and introduce new and improved products on a timely basis. We expect to commit substantial resources to develop our technologies and product applications and, in the future, to expand our commercial manufacturing capacity as volume grows. Our development efforts may be rendered obsolete by the research efforts and technological advances of others and other advanced materials may prove more advantageous than those we produce.

The markets we serve are highly competitive, and if we are unable to compete effectively, then our business will not grow.

The advanced materials industry is new, rapidly evolving and intensely competitive, and we expect competition to intensify in the future. The market for materials having the characteristics and potential uses of our nanomaterials is the subject of intensive research and development efforts by both governmental entities and private enterprises around the world. We believe that the level of competition will increase further as more product applications with significant commercial potential are developed. The nanomaterials product applications that we are developing will compete directly with products incorporating both conventional and advanced materials and technologies. While commercially available competitive products may not possess the same attributes as those we offer, other companies may develop and introduce new or competitive products. Our competitors may succeed in developing or marketing materials, technologies and better or less expensive products than the ones we offer. In addition, many of our potential competitors have substantially greater financial and technical resources, and greater manufacturing and marketing capabilities than we do. If we fail to provide nanomaterials at an acceptable price, or otherwise compete on a commodity basis with producers of conventional materials, we will lose market share and revenue to our competitors.

We may need to raise additional capital in the future. If we are unable to obtain adequate funds, we may be required to delay, scale-back or eliminate some of our manufacturing and marketing operations or we may need to obtain funds through arrangements on less favorable terms or we may be required to sell key production equipment to our largest customer.

We expect to expend resources on research, development and product testing, and in expanding current capacity or capability for new business. In addition, we may incur significant costs in preparing, filing, prosecuting, maintaining and enforcing our patents and other proprietary rights. If necessary, we may seek funding through public or private financing and through contracts with governmental entities or other companies. Additional financing may not be available on acceptable terms or at all. If we are unable to obtain adequate funds, we may be required to delay, scale-back or eliminate some of our manufacturing and marketing operations or we may need to obtain funds through arrangements on less favorable terms. If we obtain funding on unfavorable terms, we may be required to relinquish rights to some of our intellectual property.

To raise additional funds in the future, we would likely sell our equity or debt securities or enter into loan agreements. To the extent that we issue debt securities or enter into loan agreements, we may become subject to financial, operational and other covenants that we must observe. In the event that we were to breach any of these covenants, then the amounts due under such loans or debt securities could become immediately payable by us, which could significantly harm us. To the extent that we sell additional shares of our equity securities, our stockholders may face economic dilution and dilution of their percentage of ownership.

We currently have a supply agreement with BASF that contains provisions which could potentially result in a mandatory license of technology and/or sale of production equipment to BASF, providing capacity sufficient to meet BASF’s production needs. Under our supply agreement with BASF, a “triggering event” also would occur:

| • |  | if our earnings for a twelve month period ending with our most recently published quarterly financial statements are less than zero and our cash, cash equivalents and certain investments are less than $1 million, or

| • |  | upon the acceleration of any debt maturity having a principal amount of more than $10 million, or if we become insolvent as defined in the supply agreement.

14

##### Table of Contents

In the event of a triggering event where we are required to sell to BASF production equipment providing capacity sufficient to meet BASF’s production needs, the equipment would be sold at either 115% of the equipment’s net book value or at the greater of 30% of the original book value of such equipment (including any associated upgrades to it) or 115% of the equipment’s net book value, depending on the particular equipment and contract.

If we were determined to have materially breached certain other provisions of our supply agreement with BASF, we similarly could be subject to a “triggering event” that potentially could result in a mandatory license of technology and/or sale of certain production equipment to the customer.

We believe that our current cash balances and other assets that might be monetized if and as needed, as well as unused capacity that might be available for short-term borrowings, will be sufficient to avoid the first triggering event under the BASF supply agreement for the foreseeable future, and because we are debt-free, the second triggering event is not currently applicable to us.

If a triggering event were to occur and BASF elected to proceed with the license and related sale mentioned above, we would lose both significant revenue and the ability to generate significant revenue to replace that which was lost in the near term. Replacement of necessary equipment that would be purchased and removed by the customer pursuant to this triggering event could take in excess of 12 months. Any additional capital outlays required to rebuild capacity would probably be greater than the proceeds from the purchase of the assets pursuant to our agreement with BASF. This potential shortfall might put us in a position where it would be difficult to secure additional funding given what would then be an already tenuous cash position. Such an event would also likely result in the loss of many of our key staff and line employees due to economic realities. We believe that our employees are a critical component of our success and would be difficult to quickly replace and train. Upon the occurrence of such an event, we might not be able to hire and retrain skilled employees given the stigma relating to such an event and its impact on us. We might elect to effectively reduce our size and staffing to a point where we could remain a going concern in the near term.

We depend on key personnel, and their unplanned departure could harm our business.

Our success will depend, in large part, upon our ability to attract and retain highly qualified research and development, management, manufacturing, marketing and sales personnel on favorable terms. Due to the specialized nature of our business, we may have difficulty locating, hiring and retaining qualified personnel on favorable terms. If we were to lose the services of any of our key executive officers or other key personnel, or if we are unable to attract and retain other skilled and experienced personnel on acceptable terms in the future, or if we are unable to implement a succession plan to prepare qualified individuals to assume key roles upon any loss of our key personnel, then our business, results of operations and financial condition could be materially harmed.

We face potential product liability risks which could result in significant costs that exceed our insurance coverage, damage our reputation and harm our business.

We may be subject to product liability claims in the event that any of our products are alleged to be defective or cause harmful effects to humans or physical environments. Because our nanomaterials are used in other companies’ products, to the extent our customers become subject to suits relating to their products, these claims may also be asserted against us. We may incur significant costs including payment of significant damages, in defending or settling product liability claims. Although we maintain insurance for product liability claims, our coverage may not prove sufficient. Even if a suit is without merit and regardless of the outcome, claims can divert management time and attention, injure our reputation and adversely affect demand for our nanomaterials.

We may be subject to periodic litigation and other regulatory proceedings or governmental investigations, which could result in the unexpected expenditure of time and resources.

From time to time, we may be a defendant in lawsuits and regulatory proceedings or are the subject of governmental investigations relating to our business. Due to the inherent uncertainties of litigation, regulatory proceedings and governmental investigations, we cannot accurately predict the ultimate

15

##### Table of Contents

outcome of any such proceedings or investigations. An unfavorable outcome could have a material adverse impact on our business, financial condition and results of operations. In addition, regardless of the outcome of any litigation, regulatory proceedings or governmental investigations, such matters are expensive and will require that we devote substantial resources and executive time to defend, thereby diverting management’s attention and resources that are needed to successfully run our business.

The disclosure requirements under the “conflict minerals” provisions of the Dodd-Frank Act could increase our costs and limit the supply of certain metals used in our products and affect our reputation with customers and shareholders.

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, as amended, or the Dodd-Frank Act, the SEC adopted disclosure requirements, which became effective in 2014, for public companies using certain minerals and metals in their products. These minerals and metals are generally referred to as “conflict minerals” regardless of their country of origin. We anticipate commercial sales of one or more products containing these materials to begin during 2015 (energy application). Under these rules, we are required to perform due diligence and disclose our efforts to prevent the sourcing of such conflict minerals from the Democratic Republic of Congo or adjoining countries. As a result of these new regulations, we expect to incur, additional costs to comply with the disclosure requirements, including costs related to determining the source of any of the conflict minerals used in our products. These new requirements could also adversely affect the sourcing, availability and pricing of such minerals, and the pool of suppliers who provide “conflict free” metals may be limited. As a result, we or our suppliers may not be able to obtain materials necessary for production of our products in sufficient quantities or at competitive prices. In addition, we may not be able to sufficiently verify the origins of all metals used in our products and confirm that they are “conflict free,” which may adversely affect our reputation.

We are subject to governmental regulations. The costs of compliance and liability for noncompliance with governmental regulations could have a material adverse effect on our business, results of operations and financial condition.

Current and future laws and regulations may require us to make substantial expenditures for preventive or remedial action. Our operations, business or assets may be materially and adversely affected by governmental interpretation and enforcement of current or future environmental, health and safety laws and regulations. In addition, our coating and dispersion operations may pose a risk of accidental contamination or injury. The damages in the event of an accident or the costs to prevent or remediate a related event could exceed both the amount of our liability insurance and our resources or otherwise have a material adverse effect on our business, results of operations and financial condition.

In addition, both of our facilities and all of our operations are subject to the plant and laboratory safety requirements of various occupational safety and health laws. We believe we have complied in all material respects with governmental regulations applicable to us. However, we may have to incur significant costs in defending or settling future claims of alleged violations of governmental regulations and compliance with these regulations may materially restrict or impede our operations in the future. In addition, our efforts to comply with or contest any regulatory actions may distract personnel or divert resources from other important initiatives.

The manufacture and use of certain products that contain our nanomaterials are subject to extensive governmental regulation, including regulations promulgated by the FDA, the U.S. Environmental Protection Agency and OSHA. As a result, we are required to adhere to the requirements of the regulations of governmental authorities in the United States and other countries, including regulations issued to date pertaining to REACH. These regulations could increase our cost of doing business and may render some potential markets prohibitively expensive. In addition, new rules or regulations could impose restrictions or prohibitions on certain materials being marketed with or incorporated into certain applications, which could limit our ability to sell our nanomaterials in the marketplace.

A large investor and his affiliates have significant influence on all matters requiring stockholder approval because they beneficially own a large percentage of our common stock and they may vote their shares of common stock in ways with which other stockholders disagree.

16

##### Table of Contents

As of December 31, 2014, Bradford T. Whitmore, together with his affiliates, Grace Brothers, Ltd. and Grace Investments, Ltd., beneficially owned approximately 38% of the outstanding shares of our common stock. The current ownership position of Mr. Whitmore and his affiliates could delay, deter or prevent a change of control or adversely affect the price that investors might be willing to pay in the future for shares of our common stock. The interests of Mr. Whitmore and his affiliates may differ from the interests of our other stockholders and they may vote the common stock they beneficially own in ways with which our other stockholders disagree. R. Janet Whitmore, one of our directors since 2003 and a stockholder, is the sister of Mr. Whitmore.

We have never paid dividends.

We currently intend to retain earnings, if any, to support our growth strategy. We do not anticipate paying dividends on our stock in the foreseeable future.

Sales, or the availability for sale, of substantial amounts of our common stock could adversely affect the value of our common stock.

No prediction can be made as to the effect, if any, that future sales of our common stock, or the availability of our common stock for future sales, will have on the market price of our common stock. Sales of substantial amounts of our common stock in the public market and the availability of shares for future sale could adversely affect the prevailing market price of our common stock. This in turn could impair our future ability to raise capital through an offering of our equity securities.

There may be future sales or other dilution of our equity, which may adversely affect the market price of our common stock.

We are not restricted from issuing additional shares of common stock, including any securities that are convertible into or exchangeable for, or that represent the right to receive, common stock. The market price of our common stock could decline as a result of future sales of our common stock or the perception that such sales could occur.

Provisions in our certificate of incorporation, our by-laws, and Delaware law could make it more difficult for a third party to acquire us, discourage a takeover, and adversely affect existing stockholders.

Our certificate of incorporation, our by-laws and the Delaware General Corporation Law (the “DGCL”) contain provisions that may have the effect of making more difficult, delaying or deterring attempts by others to obtain control of our Company, even when these attempts may be in the best interests of stockholders. These include provisions on our maintaining a classified Board of Directors and limiting the stockholders’ powers to remove directors or take action by written consent instead of at a stockholders’ meeting. Our certificate of incorporation also authorizes our Board of Directors, without stockholder approval, to issue one or more series of preferred stock, which could have voting and conversion rights that adversely affect or dilute the voting power of the holders of common stock. The DGCL also imposes conditions on certain business combination transactions with “interested stockholders.”

These provisions and others that could be adopted in the future could deter unsolicited takeovers or delay or prevent changes in our control or management, including transactions in which stockholders might otherwise receive a premium for their shares over then current market prices. These provisions may also limit the ability of stockholders to approve transactions that they may deem to be in their best interests.

Failure to protect the integrity and security of individually identifiable data of our customers, vendors and employees could expose us to litigation and damage our reputation.

We receive and maintain certain personal, sensitive and confidential information about our customers, vendors and employees. The collection and use of this information is regulated at the international, federal and state levels, and is subject to certain contractual restrictions in third party

contracts. Although we have implemented processes to collect and protect the integrity and security of this personal information, there can be no assurance that this information will not be obtained by unauthorized persons, or collected or used inappropriately. If our security and information systems or the systems of our employees or external business associates are compromised or our employees or external business associates fail to comply with these laws and regulations and this information is obtained by unauthorized persons, or collected or used inappropriately, it could negatively affect our reputation, as well as our operations and financial results, and could result in litigation or regulatory action against us or the imposition of costs, fines or other penalties. As privacy and information security laws and regulations change, we may incur additional costs to remain in compliance.

Item 1B. | Unresolved Staff Comments

There are currently no open comments from the SEC Staff.

Item 2. | Properties

We operate two facilities in the Chicago suburbs - a 36,000 square-foot production, research and headquarters facility in Romeoville, Illinois and a 20,000 square-foot production facility in Burr Ridge, Illinois. We also lease a 9,000 square-foot offsite warehouse in the vicinity of the Romeoville facility.

Our manufacturing operations in Burr Ridge are certified under ISO 9001:2008, and we believe that our manufacturing operations are within the cGMP requirements of the FDA for products that require such compliance. Our facilities are also ISO 14001:2004 certified which is the international standard for environmental management. The Burr Ridge facility has a quality control laboratory designed for the dual purposes of validating operations to cGMP and ISO standards and production process control. This laboratory is equipped to handle many routine analytical and in-process techniques that are currently required.

The Romeoville facility houses our headquarters, advanced engineering, manufacturing (including nanoparticle coating, nanoparticle dispersion and pilot-scale manufacturing) and research and development with three applications development laboratories. All Romeoville manufacturing processes are certified to ISO 9001:2008 and ISO 14001:2004, and we believe that the manufacturing of nanoparticle coating used for sunscreens and personal care is in compliance with the cGMP requirements of the FDA.

We lease our Romeoville and Burr Ridge facilities. During November 2014 we entered into a Lease Amendment amending the then-current lease for the facility in Romeoville, Illinois, which, among other things, extended the term of such lease through December 31, 2019 (with our option to extend the term for an additional five-year period). We renewed the Burr Ridge facility lease in September 2010, extending the terms through September 2014 (we subsequently exercised our option to extend the term through September 2016, and have the option to extend the term for one additional one-year period). During 2013 we also renewed the lease for our offsite warehouse through August 2016.

We believe that our leased facilities provide sufficient capacity to fulfill current known customer demand as well as allow for the creation of substantial additional space to enable expansion of key production processes. We believe additional facilities could be obtained in the area at competitive prices if necessary to support growth. We believe that our capital expenditures made in 2014, and projected for 2015, will support currently anticipated demand from existing customers. Our actual future capacity requirements will depend on many factors, including new and potential customer acceptance of our current and potential nanomaterials and product applications, both expected and currently unplanned growth from existing customers, continued progress in our research and development activities and product testing programs and the magnitude of these activities and programs.

Overview

Nanophase is an advanced materials and applications developer and commercial manufacturer with an integrated family of materials technologies. We produce engineered nano and sub-micron materials for use in a variety of diverse markets: personal care including sunscreens, architectural coatings, industrial coating applications, abrasion-resistant additives, plastics additives, medical diagnostics, energy, and a variety of surface finishing technologies (polishing) applications, including optics. We target markets in which we believe practical solutions may be found using our products. We work closely with current and potential customers in these target markets to identify their material and performance requirements and market our materials to various end-use applications manufacturers. Recently developed technologies have made certain new products possible and opened potential new markets. For example, we have applied our skills at producing precisely defined nanomaterials to now create and sell larger, sub-micron material products. Our focus is on customer need where we believe we have an advantage, as opposed to finding uses for one particular technology. We expect growth in end-user (manufacturing customers, including customers of our customers) adoption in 2015 and beyond. Our initiatives in targeted market areas are progressing at differing rates of speed, but we have been broadly moving through testing and development cycles, and in a number of cases believe we are approaching first revenue or next stage revenue with particular customers in the industries referenced above. For example, during 2014 we developed new solutions in the surface finishing technologies (polishing) and energy-management areas that were presented to potential customers during the year and have already resulted in accelerating order flows in the former and significant commercial testing in the latter. We believe that successful introduction of our materials with manufacturers may lead to follow-on orders for other materials in their applications. We expect that we will both work more deeply with current customers and attract additional customers, which should help us achieve growth in these markets in 2015 and beyond.

Critical Accounting Estimates

We review long-lived assets for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. We conduct long-lived asset impairment analyses in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 360-10-15, Impairment or Disposal of Long-Lived Assets. ASC 360-10-15 requires us to group assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows. If the undiscounted cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals.

Certain assumptions are necessary to assess the impact of risks and uncertainties on the financial information, such as cash flow projections, availability of capital if needed to support the ongoing operations of the business, and our expected compliance with contractual commitments. Any changes in those plans or assumptions could have a material impact on our liquidity and financial condition.

Results of Operations

Years Ended December 31, 2014 and 2013

Total revenue increased to $9,936,000 in 2014, compared to $9,590,000 in 2013. A substantial majority of our revenue for each year is from our largest customers, in particular sales to our largest customer in personal care and sunscreen applications. Product revenue, the primary component of our total revenue, increased to $9,880,000 in 2014, compared to $9,566,000 in 2013. This increase was primarily due to increased revenue from our largest customer, as well as increased revenue from our customer in medical diagnostics and increased revenues in our surface finishing (polishing) applications, offset in part by a reduction from one of our two largest coatings customers. Revenue from our top three customers was approximately 72%, 6% and 5%, respectively, in 2014, compared to 72%, 3% and 6% for the same customers in 2013.

Other revenue increased to $56,000 in 2014, compared to $24,000 in 2013. The increase was primarily related to a fee-based project that was completed and we do not expect to be repeated during the foreseeable future.

Cost of revenue generally includes costs associated with commercial production and customer development arrangements. Cost of revenue increased to $7,105,000 in 2014, compared to $7,030,000 in 2013. The increase in cost of revenue was primarily driven by the increase in product revenue volume, offset by a reduction in depreciation expense related to fully depreciated equipment and efficiencies gained in the production system. We expect to continue new nanomaterial development, primarily using our NanoArc® synthesis and dispersion technologies, for targeted applications and new markets during 2015 and beyond. At current revenue levels we have generated a positive gross margin, though margins have been impeded by not having enough revenue to efficiently absorb manufacturing overhead that is required to work with current customers and expected future customers. We believe that our current fixed manufacturing cost structure is sufficient to support significantly higher levels of production. The extent to which margins grow, as a percentage of total revenue, will be dependent upon revenue mix, revenue volume, our ability to continue to cut costs and pass commodity market-driven raw materials increases on to customers. As product revenue volume increases, this should result in our fixed manufacturing costs being more efficiently absorbed, leading to increased margins. We expect to continue to focus on reducing controllable variable product manufacturing costs, with potential variability related to the commodity metals markets, but may or may not continue to realize absolute dollar gross margin growth through 2015 and beyond, dependent upon the factors discussed above.

Research and development expense, which includes all expenses relating to the technology and advanced engineering groups, primarily consists of costs associated with the development or acquisition

of new product applications and coating formulations and the cost of enhancing our manufacturing processes. As an example, we have been, and continue to be, engaged in research to enhance our ability to disperse material in a variety of organic and inorganic media for use as coatings and polishing materials, including polishing products. Much of this work has led to several new products and additional potential new products.

Having demonstrated the capability to produce pilot quantities of mixed-metal oxides in a single crystal phase, we do not expect development of further variations on these materials to present material technological challenges. Many of these materials exhibit performance characteristics that can enable them to serve in various catalytic applications. We are now working on several related commercial opportunities using the same materials. We expect that this technique should enable us to scale to large quantity commercial volumes. We also have an ongoing advanced engineering effort that is focused on the development of new nanomaterials as well as the refinement of existing nanomaterials, as dictated by our customer-driven marketing strategy. We are not certain when or if any significant revenue will be generated from the production of the materials described above.

Research and development expense decreased to $1,338,000 in 2014, compared to $1,679,000 in 2013. The primary reasons for this decrease were reduced product development costs (salaries and materials) as we transferred new material solutions in the energy sector from development to operations for commercial activity and wage and benefit savings associated with lower staffing. We expect an approximately 10% increase in spending in this area during 2015 as we begin additional development projects and add to our staff.

Selling, general and administrative expense decreased to $3,215,000 in 2014, compared to $3,372,000 in 2013. The net decrease was primarily attributed to decreased salary and personnel costs, partially offset by increases in consulting fees and marketing and selling expenses, all related to our stronger focus on a few, well-qualified initiatives and the advancement of development projects into commercial applications. We expect 2015 costs to be approximately 8% higher and driven largely by the selling function, depending on the status of certain initiatives.

Interest income was insignificant during both periods, as it decreased to $810 in 2014, compared to $1,501 in 2013. The decrease was primarily due to small investment yields not offset by bank related fees and limited excess cash for investment purposes.

Inflation

We believe inflation has not had a material effect on our operations or financial position. However, supplier price increases and wage and benefit inflation, both of which represent a significant component of our costs of operations, may have a material effect on our operations and financial position in 2015 and beyond if we are unable to pass through any increases under present contracts or through to our markets in general.

Liquidity and Capital Resources

Our cash, cash equivalents and short-term investments amounted to $1,862,000 as of December 31, 2014, compared to $3,306,000 on December 31, 2013. The net cash used in our operating activities for the year ended December 31, 2014 was $1,181,000 compared to $522,000 for the year ended December 31, 2013. The 2014 figure includes approximately $400,000 of working capital spending while the 2013 figure includes $800,000 in working capital benefit primarily related to the timing of receivables collections and fourth quarter shipment dates. Net cash used in investing activities amounted to $239,000 for the year ended December 31, 2014, compared to $276,000 for the year ended December 31, 2013. Capital expenditures amounted to approximately $400,000 (including one new capital lease for $200,000) and $300,000 (with no new capital leases) for the years ended December 31, 2014 and 2013, respectively. Net cash provided by financing activities was $6,000 in 2014, compared to a use of $50,000 in cash used in financing activities in 2013.

Our supply agreements with our largest customer, BASF, contain certain financial covenants which could potentially impact our liquidity. The most restrictive financial covenants under these agreements require that we maintain a minimum of $1 million in cash, cash equivalents and certain investments, and that we not have the acceleration of any debt maturity having a principal amount of more than $10 million, in order to avoid triggering the customer’s potential right to transfer certain technology and equipment to that customer at a contractually defined price. We had approximately $1.9 million in cash on December 31, 2014, and no debt.

We believe that cash from operations and cash on hand, in addition to unused borrowing capacity which might be used to secure financing, will be adequate to fund our operating plans through 2015. Our actual future capital requirements in 2015 and beyond will depend, however, on many factors, including customer acceptance of our current and potential nanomaterials and product applications, continued progress in research and development activities and product testing programs, the magnitude of these activities and programs, and the costs necessary to increase and expand our manufacturing capabilities and to market and sell our materials and product applications. Other important issues that will drive future capital requirements will be the development of new markets and new customers as well as the potential for significant unplanned growth with existing customers. Depending on the success of certain projects, we expect that capital spending relating to currently known capital needs for 2015 will be between $300,000 and $450,000. If those projects are delayed or ultimately prove unsuccessful, we would expect our capital requirements to be toward the lower end of the range. Similarly, substantial success in business development projects may cause the actual 2015 capital investment to exceed the top of this range.

Should events arise that make it appropriate for us to seek additional financing, such additional financing may not be available on acceptable terms or even at all, and any such additional financing could be dilutive to our shareholders. Such financing could be necessitated by such things as the loss of existing customers; currently unknown capital requirements in light of the factors described above; new regulatory requirements that are outside our control; the need to meet previously discussed cash requirements to avoid a triggering event under our BASF agreement; or various other circumstances coming to pass that we currently do not anticipate. The failure to have access to sufficient capital to fund our business plans may result in a curtailment or other change in those plans.

On December 31, 2014, we had a net operating loss carryforward of approximately $80 million for income tax purposes. Because the Company may have experienced “ownership changes” within the meaning of the U.S. Internal Revenue Code in connection with its various prior equity offerings, future utilization of this carryforward may be subject to certain limitations as defined by the Internal Revenue Code. If not utilized, the remaining carryforward will expire at various dates between January 1, 2018 and December 31, 2034. As a result of the annual limitation and uncertainty as to the amount of future taxable income that will be earned prior to the expiration of the carryforward, we have concluded that it is likely that some portion of this carryforward will expire before ultimately becoming available to reduce income tax liabilities. Changes in Illinois state tax law beginning in 2011 may impact net loss carryforward duration and utilization on the state tax level.

Off-Balance Sheet Arrangements

We have not created, and are not party to, any special-purpose or off-balance sheet entities for the purposes of raising capital, incurring debt or operating our business. We do not have any off-balance sheet arrangements or relationships with entities that are not consolidated into our financial statements that are reasonably likely to materially affect our liquidity or the availability of capital resources.

As more fully described in Note 3 to our Financial Statements, referenced in Part II, Item 8 and set forth on page F-10 of this Form 10-K, during July 2014 we entered into a new bank-issued letter of credit and promissory note for up to $30,000 supporting our obligations under our facility lease agreement. No borrowings have been incurred under this promissory note.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2014. In making this assessment, management used the criteria established in Internal Control–Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based on our assessment and those criteria, management believes that the Company maintained effective internal control over financial reporting as of December 31, 2014.

This annual report does not include an attestation report of the Company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to the rules of the Securities and Exchange Commission that permit the company to provide only management’s report in this annual report.

Changes in Internal Control over Financial Reporting. The Company’s management, including Mr. Jankowski, the CEO, and Mr. Cesario, the CFO, confirms that there was no change in the Company’s internal control over financial reporting during the quarter ended December 31, 2014 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Meetings of the Board and Committees — During the year ended December 31, 2014, the Board of Directors held four meetings. No director missed more than one board or committee meeting held during 2014 (for all committees on which a particular director served).

Committees of the Board of Directors — The Board of Directors has established an Audit and Finance Committee, Compensation Committee and Nominating and Corporate Governance Committee. Each operates in accordance with its charter (available on our website www.nanophase.com under the “Investor Relations” section). The members of the Audit and Finance Committee are Mr. McClung (Chairman), Mr. Vincent and Dr. Siegel. The members of the Compensation Committee are Mr. Tyler (Chairman), Mr. Henderson, and Mr. Vincent. The members of the Nominating and Corporate Governance Committee are Mr. Henderson (Chairman), Mr. McClung, Dr. Siegel, Mr. Vincent, Mr. Tyler and Ms. Whitmore.

The Audit and Finance Committee generally has responsibility for retaining the Company’s independent public auditors, reviewing the plan and scope of the accountants’ annual audit, reviewing the Company’s internal control functions and financial management policies, reviewing and approving all related party transactions, and reporting to the Board of Directors regarding all of the foregoing. The Audit and Finance Committee held seven meetings during 2014. The Board of Directors has determined that Mr. Vincent and Mr. McClung are the “audit committee financial experts” as described in applicable SEC rules. Each member of the Audit and Finance Committee is independent, as defined in applicable SEC rules.

The Compensation Committee generally has responsibility for establishing executive officer and key employee compensation, reviewing and establishing the Company’s executive compensation, evaluating our Outside Director compensation, and reporting to the Board of Directors regarding the foregoing. The Compensation Committee also has responsibility for administering the 2010 Equity Plan, determining the number of options, if any, to be granted to the Company’s employees and consultants pursuant to the 2010 Equity Plan and reporting to the Board of Directors regarding the foregoing. Regarding most compensation matters, including executive compensation, our management provides recommendations to the Compensation Committee; however, the Compensation Committee does not delegate any of its functions to others in setting compensation. The Compensation Committee does not currently utilize external consultants in executive or director compensation matters. The Compensation Committee held two meetings during 2014. Each member of the Compensation Committee is independent, as defined in applicable SEC rules, is a “non-employee director” as defined in Rule 16b-3 under the Exchange Act and is an “Outside Director” as defined by the regulations under Section 162(m) of the Internal Revenue Code.

The Nominating and Corporate Governance Committee generally has responsibility for evaluating and nominating candidates to serve on the Board of Directors, and for establishing and reviewing our Corporate Governance Principles. Five of the six members of the Nominating and Corporate Governance Committee are independent, as defined in applicable SEC rules. The Nominating and Corporate Governance Committee held two meetings during 2014.

The Board of Directors considers its role in risk oversight to focus primarily on evaluating risk at the entity and strategic levels, with management primarily responsible for managing day-to-day risk factors and presenting summary materials for those positions to the Board of Directors. Consistent with this philosophy, the Board of Directors has no formal policy as to whether the roles of Chief Executive Officer and Chairman should be segregated or combined. The Board of Directors considers the circumstances of the Company and makes a determination as to the appropriate leadership structure for the Company at that time. As of the time of this filing, the positions of CEO and Chairman are held by two individuals – Mr. Henderson serves as Chairman and Mr. Jankowski serves as CEO. Mr. Henderson brings extensive experience in corporate leadership from his own working experience and from the many Boards on which he serves or has served in the past, and Mr. Jankowski is expected to benefit from that experience. The Board of Directors believes that is the most appropriate structure for the Company at this time. Under our Corporate Governance Principles, in the event that the Chairman of the Board is not an Outside Director, the Board will elect a lead independent director, who will have the responsibility to

28

##### Table of Contents

schedule and prepare agendas for meetings of the Outside Directors, communicate with the CEO, disseminate information to the rest of the Board and raise issues with management on behalf of the Outside Directors when appropriate. The Board evaluates its leadership structure on an ongoing basis and may change it as circumstances warrant.

The Board of Directors does not have a stated policy regarding diversity, although pursuant to our Corporate Governance Principles, diversity is one factor that the Nominating and Corporate Governance Committee considers when recommending directors for stockholder approval. The Board seeks experienced individuals for service who bring extensive experience in leadership, operations, finance, and engineering, particularly in areas directly applicable to the Company or its intended future endeavors.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16 of the Exchange Act requires the Company’s officers (as defined under Section 16), directors and persons who beneficially own greater than 10% of a registered class of our equity securities to file reports of ownership and changes in ownership with the SEC. Based solely on a review of the forms we have received and on written representations from certain reporting persons that no such forms were required for them, we believe that during 2014 all Section 16 filing requirements applicable to our officers, directors and 10% beneficial owners were complied with by such persons except as follows: a Form 4 filing related to a May 14, 2014 stock purchase by Ms. Whitmore was filed 3 days late, a Form 4 filing related to a May 20, 2014 stock purchase by Ms. Whitmore was filed 1 day late, and a Form 4 filing related to a December 23, 2014 stock purchase by Mr. Henderson was filed 1 day late.

CODE OF ETHICS

We have adopted a Code of Business Conduct and Ethics (“Code of Ethics”) that applies to, among others, our principal executive officer, principal financial officer and principal accounting officer or controller, or persons performing similar functions. The Code of Ethics is posted on our Internet website www.nanophase.com under the “Investor Relations” section. In the event that we make any amendment to, or grants any waiver from, a provision of the Code of Ethics that requires disclosure under applicable SEC rules, we intend to disclose such amendment or waiver on our website.

Item 11. | Executive Compensation

Compliance with Section 162(m)

The Compensation Committee currently intends for all compensation paid to the executive officers to be tax deductible to the Company pursuant to Section 162(m) of the Internal Revenue Code (“Section 162(m)”). Section 162(m) provides that compensation paid to the executive officers in excess of $1,000,000 cannot be deducted by the Company for Federal income tax purposes unless, in general, (1) such compensation is performance-based, established by a committee of Outside Directors and objective, and (2) the plan or agreement providing for such performance-based compensation has been approved in advance by stockholders. The Compensation Committee may determine to adopt a compensation program that does not satisfy the conditions of Section 162(m) if in its judgment, after considering the additional costs of not satisfying Section 162(m), it deems such program to be appropriate.

(1) | Any amounts earned during 2014 and 2013 would have been paid in early 2015 and 2014, respectively. Bonus compensation is driven by Company performance against its goals as ultimately determined by the Compensation Committee of the Board of Directors. A set of Company-level objectives is created at the beginning of the year, focusing on total revenue, revenue growth, particular sources of revenue growth, business development achievements, cash flows and related targets, as well as a small discretionary component designed to capture items not specifically listed. Each measure has varying levels of achievement, which is reflected in the aggregate bonus measurement. The resulting bonus calculation is then applied to each individual’s bonus potential as a percentage of salary. Because total revenue growth was only 4% during 2014 and did not increase during 2013, performance targets were not met and thus no bonus was awarded to any of the named executive officers for 2014 or 2013.

(2) | The amounts in this column represent the aggregate fair value of awards granted in 2014 and 2013 fiscal years in accordance with FASB ASC Topic 718. See Note 10 of the notes to our financial statements contained elsewhere in this Form 10-K for a discussion of all assumptions made by us in determining the FASB ASC Topic 718 values.

(3) | None.

(4) | The amounts in this column represent 401(k) match, health and life insurance. Health insurance benefits are the same for all employees. Life insurance is provided in the amount of one times the annual base salary with a maximum of $150,000.

(5) | Dr. Murray resigned from his position as Vice President Research and Development effective December 5, 2014.

Employment Agreements

In addition, all stock options granted to Mr. Jankowski prior to termination will become fully vested and exercisable in accordance with the applicable option grant agreement and the 2010 Equity Plan. If he is terminated for cause, or if he resigns as an employee of the Company, Mr. Jankowski will not be entitled to any severance or other benefits accruing after the term of the employment agreement and such rights will be forfeited immediately upon the end of such term.

If, within two years after the occurrence of a change in control, as defined in his employment agreement, Mr. Jankowski’s employment is terminated other than for cause, his responsibilities or annual compensation are materially reduced without his prior consent, or we cease to be publicly held (each, a “Trigger”), then, subject to Mr. Jankowski signing, without subsequently revoking, a Separation Agreement and Release in a form acceptable to us, Mr. Jankowski will receive a sum equal to his base salary for 104 full weeks after the date the Trigger occurs.

No term has been assigned to Mr. Cesario’s employment agreement.

A signing bonus of $25,000 was paid upon Mr. Cureton’s acceptance of employment.

POTENTIAL PAYMENT UPON TERMINATION OR CHANGE IN CONTROL

Severance Benefits. Please see discussion of severance benefits under “Employment Agreements” above.

Change in Control. Upon a change in control, the 2010 Equity Plan provides that: (1) vesting under all outstanding stock options will automatically accelerate and each option will become fully exercisable; (2) the restrictions and conditions on all outstanding restricted shares shall immediately lapse; and (3) the holders of performance shares will receive a payment in settlement of the performance shares, in an amount determined by the Compensation Committee, based on the target payment for the performance period and the portion of the performance period that precedes the change in control. If the Company is not the surviving entity, the successor is required to assume all unexercised options.

Payments. The following table quantifies the estimated payments that would be made in each covered circumstance to our named executive officers:

NAME |  | TERMINATION BY COMPANY WITHOUT CAUSE (1) |  |  | CHANGE IN CONTROL (2) |  |  | INVOLUNTARY TERMINATION IN CONNECTION WITH OR FOLLOWING A CHANGE IN CONTROL (3) |
Jess Jankowski |  | $ | 301,000 |  |  | $ | 3,267 |  |  | $ | 602,000 |

##### Table of Contents

| (1) | This amount represents the severance benefits that would be received under the executive officer’s employment agreement as described had the executive officer been terminated by the Company without cause on December 31, 2014.

| (2) | This amount represents an estimate of the value that would have been received under the equity compensation plans had a change in control occurred as of December 31, 2014 and the executive officers benefited from an acceleration of vesting in the equity-based plan awards, as described above. For this purpose, the closing price of our common stock as of December 31, 2014 was used. The amount represents the difference between the exercise price of any unvested options and $0.40.

| (3) | This amount represents an estimate of the payments and value (in addition to any acceleration of vesting of equity-based awards) that would have been received by the executive officers had the executive officers been terminated by the Company without cause on December 31, 2014 in connection with a change in control on this date.

Upon his resignation effective December 5, 2014, Dr. Murray did not receive any severance benefits or any accelerated vesting of his equity-based awards.

DIRECTOR COMPENSATION

Upon first being elected to the Board of Directors, each director of the Company who is not an employee or consultant of the Company (an “Outside Director”) is granted stock options to purchase shares of common stock at the closing price as of the date of issuance (the fair market value). This initial option grant to an Outside Director typically vests over three years, though may accelerate upon termination from the Board of Directors.

In 2014, we paid quarterly compensation to the Chairman of the Board of Directors, for an annual rate of $19,250. We paid quarterly compensation to the Chairman of the Audit and Finance Committee and to the Chairman of the Compensation Committee totaling $15,750 to each. Each of our other Outside Directors was paid quarterly compensation for an annual total of $14,000 per Outside Director for services performed in their capacity as a director.

During the first quarter of 2014, we granted our Outside Directors stock options totaling 69,000 shares under the 2010 Equity Plan, as follows: the Chairman of the Board of Directors received stock options to purchase 15,000 shares of our common stock, the Chairman of the Audit and Finance Committee and the Chairman of the Compensation Committee each received stock options to purchase 12,000 shares of our common stock and each of our other Outside Directors received stock options to purchase 10,000 shares of our common stock. Our Outside Directors had the following shares of our common stock underlying stock options (both vested and unvested) outstanding as of December 31, 2014: Mr. Henderson: 55,000 shares; Mr. McClung: 48,000 shares; Mr. Vincent: 54,000 shares; Ms. Whitmore: 40,000 shares; Mr. Siegel: 40,000 shares; and Mr. Tyler: 44,000 shares.

Prior to 2011, we granted our Outside Directors stock appreciation rights (SARs) totaling 106,750 shares, under our Amended and Restated 2006 Stock Appreciation Rights Plan and subsequently under the 2010 Equity Plan. No SARs were granted during 2013 or 2014. The SARs granted vested immediately and are payable upon the directors’ termination from the position of director. The fair value of the liability for the 73,500 shares that were outstanding on December 31, 2014 was approximately $1,000.

In 2013, we paid quarterly compensation to the Chairman of the Board of Directors for an annual rate of $22,000. We paid quarterly compensation to the Chairman of the Audit and Finance Committee and the Chairman of the Compensation Committee totaling $18,000 each. We paid all other Outside Directors quarterly compensation amounting to an annual total of $16,000 per Outside Director for services performed in their capacity as directors.

##### Table of Contents

In 2005, we adopted, and our stockholders approved, the 2005 Non-Employee Director Restricted Stock Plan (the “Director Restricted Stock Plan”) which reserved 150,000 shares of our common stock to be issued to Outside Directors in the form of restricted shares. In 2005, no awards were made under the Director Restricted Stock Plan. In 2005, we also adopted the Non-Employee Director Deferred Compensation Plan (the “Director Deferred Compensation Plan”) which permits an Outside Director to defer the receipt of director fees until separation from service or the Company undergoes a change in control. We amended the Director Restricted Stock Plan in 2005 to permit an Outside Director to defer receipt of restricted stock granted under it. The deferred restricted shares are accounted for under the Director Deferred Compensation Plan and issued upon separation from service or the Company’s change in control. Under the Director Deferred Compensation Plan, the deferred fees that would have been paid in cash are deemed invested in 5 year U.S. Treasury Bonds during the deferral period. The accumulated hypothetical earnings are paid following the Outside Director’s separation from service or the Company’s change in control. The deferred fees that would have been paid as restricted shares are deemed invested in our common stock during the deferral period. The Director Deferred Compensation Plan is an unfunded, nonqualified deferred compensation arrangement. In 2009, all Outside Directors elected to defer receipts of all of the restricted shares they became entitled to under the Director Restricted Stock Plan, which was consolidated into the 2010 Equity Plan.

Under our Audit and Finance Committee’s charter, the Audit and Finance Committee must review and approve all related person transactions in which any executive officer, director, director nominee or more than 5% stockholder, or any of their immediate family members, has a direct or indirect material interest. The Audit and Finance Committee may not approve a related person transaction unless it is in, or not inconsistent with, our best interests and, where applicable, the terms of such transaction are at least as favorable to us as could be obtained from an unrelated third party.

We did not engage in any transactions in which a related person had or will have a direct or indirect material interest during 2013 or 2014. No such transactions are currently contemplated.

Audit services include the auditing of financial statements and quarterly reviews.

Total audit related fees billed by McGladrey LLP was approximately none and $4,000 for the years ended December 31, 2014 and 2013, respectively, which may include costs incurred for reviews of registration statements, assistance with Staff comment letters, and consultation on various accounting matters in support of our financial statements.

All Other Fees. Other than those fees described above, during the fiscal years ended December 31, 2014 and 2013, there were no other fees billed for services performed by our principal accountant.

All of the fees described above were approved by our Audit and Finance Committee.

Audit and Finance Committee Pre-Approval Policies and Procedures. Nanophase’s Audit and Finance Committee pre-approves the audit and non-audit services performed by McGladrey LLP, our principal accountants, in order to assure that the provision of such services does not impair McGladrey LLP’s independence. Unless a type of service to be provided by McGladrey LLP has received general pre-approval, it will require specific pre-approval by the Audit and Finance Committee. In addition, any proposed services exceeding pre-approval cost levels or budgeted amounts will require specific pre-approval by the Audit and Finance Committee.

The term of any pre-approval is 12 months from the date of pre-approval, unless the Audit and Finance Committee specifically provides for a different period. The Audit and Finance Committee will periodically revise the list of pre-approved services, based on subsequent determinations, and has delegated pre-approval authority to the Chairman of the Audit and Finance Committee. In the event the Chairman exercises such delegated authority, he shall report such pre-approval decisions to the Audit and Finance Committee at its next scheduled meeting. The Audit and Finance Committee does not delegate its responsibilities to pre-approve services performed by the independent auditor to management.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders

Nanophase Technologies Corporation

We have audited the accompanying balance sheets of Nanophase Technologies Corporation as of December 31, 2014 and 2013, and the related statements of operations, stockholders’ equity, and cash flows for the years then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Nanophase Technologies Corporation as of December 31, 2014 and 2013, and the results of its operations and its cash flows for the years then ended, in conformity with U.S. generally accepted accounting principles.

NANOPHASE TECHNOLOGIES CORPORATION

NOTES TO FINANCIAL STATEMENTS

(In thousands, except share and per share data or as otherwise noted herein)

(1) | Description of Business

Nanophase is an advanced materials and applications developer and commercial manufacturer with an integrated family of nanomaterial and related technologies. We produce engineered nano and larger, sub-micron, materials for use in a variety of diverse markets: personal care including sunscreens, architectural coatings, industrial coating applications, abrasion-resistant additives, plastics additives, medical diagnostics, energy, and a variety of surface finishing technologies (polishing) applications. We target markets in which we believe practical solutions may be found using our products. We work closely with current and potential customers in these target markets to identify their material and performance requirements and market our materials to various end-use applications manufacturers. Recently developed technologies have made certain new products possible and opened potential new markets. We recently developed new material solutions in surface finishing technologies (polishing) and energy-management areas that have been taken to potential customers, and for which we are experiencing accelerating revenue growth (former) and are in the process of commercial testing and qualification (latter). Although our primary strategic focus has been the North American market, we currently sell material to customers overseas and have been working to expand our reach within foreign markets. The Company was incorporated in Illinois on November 25, 1989, and became a Delaware corporation during November 1997. Our common stock trades on the OTCQB marketplace under the symbol NANX.

While product sales comprise the majority of our revenue, we also recognize revenue from other sources from time to time. These activities are not expected to drive the long-term growth of the business. For this reason, we classify such revenue as “other revenue” in our Statements of Operations, as it does not represent revenue directly from our nanocrystalline materials.

(2) | Summary of Significant Accounting Policies

Use of Estimates and Risks and Uncertainties

The preparation of financial statements requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Certain assumptions are also necessary to assess the impact of risks and uncertainties on the financial statements, such as cash flow projections, availability of capital if needed to support the ongoing operations of the business, and our expected compliance with contractual commitments. These risks and uncertainties are further discussed in Note 12. Any changes in these assumptions or business plans could have a material impact on the financial statements.

Cash and Cash Equivalents

Cash and cash equivalents primarily consist of demand deposits, but also include certain lower risk investments with a stated maturity upon acquisition of 90 days or less (e.g., money market funds or a certificate of deposit with a maturity of 90 days or less at the time of purchase).

Trade Accounts Receivable

Trade accounts receivable are carried at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. We determine the allowance for doubtful accounts by identifying troubled accounts and by using historical experience applied to an aging of accounts. Trade accounts receivable are written off when deemed uncollectible. Recoveries of trade accounts receivable previously written off are recorded when received. Our typical credit terms are thirty days from shipment and invoicing.

Inventories

Inventories are stated at the lower of cost, maintained on a first in, first out basis, or market. We have recorded allowances to reduce inventory relating to excess quantities of certain materials. Write-downs of inventories establish a new cost basis, which is not increased for future increases in market value of inventories or changes in estimated excess quantities.

Equipment and Leasehold Improvements

Equipment is stated at cost and is being depreciated over its estimated useful life (3-20 years) using the straight-line method. Leasehold improvements are stated at cost and are being amortized using the straight-line method over the shorter of the useful life of the asset or the term of the lease (3-13 years). Depreciation expense for leased assets is included with depreciation expense for owned assets. From time to time we have self-constructed assets. These assets are stated at cost plus the capitalization of labor and are depreciated over an estimated useful life (7-10 years) using the straight-line method.

Long Lived Assets

We review long-lived assets for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. We conduct long-lived asset impairment analyses in accordance with ASC 360-10-15, Impairment or Disposal of Long-Lived Assets. ASC 360-10-15 requires us to group assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows. If the undiscounted cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals.

Asset Retirement Obligations

In connection with our leased facilities, we are required to remove certain leasehold improvements upon termination of our occupancy. We follow the provisions of the FASB issued ASC 410-20, Asset Retirement Obligations, under which we recognize a liability for the fair value of these asset retirement obligations. The fair value of that liability is measured based on an expected cash flow approach and accretion expense is recognized each period to recognize increases to the fair value of the liability due to the passage of time. Increases to the fair value of the liability, except for accretion, are added to the carrying value of the long-lived asset. Those increases are then reported in amortization expense over the estimated useful life of the long-lived asset.

Activity in the asset retirement obligation account for the years ended December 31, is as follows:

|  | 2014 |  |  | 2013 |
Balance, beginning |  | $ | 160 |  |  | $ | 154 |
Accretion of liability due to passage of time |  |  | 6 |  |  |  | 6 |
Amortization of asset due to passage of time |  |  | — |  |  |  | — |
Balance, ending |  | $ | 166 |  |  | $ | 160 |

##### Table of Contents

Financial Instruments

We follow ASC Topic 820, Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. The fair value framework requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment.

Our financial instruments include cash and cash equivalents, accounts receivable, accounts payable and accrued expenses, along with the promissory note with no related borrowings described in Note 3. The fair values of all financial instruments were not materially different from their carrying values.

There were no financial assets or liabilities adjusted to fair value on December 31, 2014 and 2013.

Product Revenue

Product revenue consists of sales of product that are recognized when realized and earned. This occurs when persuasive evidence of an arrangement exists, title transfers via shipment of products or when delivery has occurred, the price is fixed or determinable and collectability is reasonably assured.

Other Revenue

Other revenue may include revenue from technology license fees and paid development projects. Technology license fees and paid development projects are recognized when earned pursuant to the agreed upon contractual arrangement, when performance obligations are satisfied, the amount is fixed or determinable, and collectability is reasonably assured.

Shipping and handling costs are included in other revenue when products are shipped and invoiced to the customer. We include the related cost of shipping and handling in cost of goods sold.

Research and Development Expenses

Research and development expenses are recognized as expense when incurred.

Income Taxes

We account for income taxes using the liability method. As such, deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred tax assets and liabilities are calculated using the enacted tax rates and laws that are expected to be in effect when the anticipated reversal of these differences is scheduled to occur. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax

F-9

##### Table of Contents

positions taken that exceeds the amount measured, as described above, is reflected as a liability for uncertain tax benefits in the accompanying balance sheets along with any associated interest and penalties that would be payable to the taxing authorities upon examination.

We have not recorded a reserve for any tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. We file tax returns in all appropriate jurisdictions, which includes a federal tax return and Illinois state tax return. Open tax years for both jurisdictions are 2011 to 2013, which statutes expire in 2015 to 2017, respectively, under most cases and subject to appropriate laws and regulations. When and if applicable, potential interest and penalty costs are accrued as incurred, with expenses recognized in selling, general and administrative expenses in the statements of operations. As of December 31, 2014 and 2013, we had no liability for unrecognized tax benefits.

Earnings Per Share

Net loss per common share is computed based upon the weighted average number of common shares outstanding. No equivalent shares are included in 2014 and 2013 because the effect of these securities is anti-dilutive, and because the impact on a per share basis would not be meaningful.

New Accounting Pronouncement

During May 2014, the FASB issued ASU No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers, which supersedes nearly all existing revenue recognition guidance under U.S. generally accepted accounting principles. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. Additionally, the guidance requires certain disclosures designed to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, which is our first quarter of 2017. Early application is not permitted. The new standard allows application either retrospectively to each prior reporting period presented or retrospectively as a cumulative-effect adjustment as of the date of adoption. We are evaluating the effect that ASU 2014-09 will have on our financial statements and related disclosures, but do not expect it to have a material impact on our financial position, results of operations, or cash flows.

(3) | Investments and Outstanding Note

Investments on December 31, 2013 were comprised of certificates of deposit in the amount of $30, pledged as collateral for our rent and restricted as to withdrawal or usage under our facility lease agreement. During July 2014 we entered into a new bank-issued letter of credit and related promissory note for up to $30 in borrowings to support our obligations under our facility lease agreement. We then sold our certificates of deposit. No borrowings have been incurred under this promissory note. Should any borrowings occur in the future, the interest rate would be the prime rate plus 1%, with the bank having the right to “set off” or apply unpaid balances against our checking account if we fail to meet our obligations under any borrowings under the note. It is our intention to renew this note annually, for as long as we need to pursuant to the terms of our facility lease agreement. Because there were no amounts outstanding on the note at any time during 2014, we have recorded no related liability on our balance sheet.

Depreciation expense was $734 and $866, for the years ended December 31, 2014 and 2013, respectively.

(6) | Lease Commitments

We lease our operating facilities under operating leases. During November 2014 we entered into a Second Lease Amendment related to our primary facility in Romeoville, Illinois, extending the term of the lease through December 31, 2019 (with our option to extend the term for an additional five-year period). The current monthly rent on this lease amounts to $29.

We lease our Burr Ridge, Illinois, facility under an agreement most recently extended during September 2010, which extended the term through September 2014 (we have since exercised options to extend the term through September 2016 and have the option to extend the term for an additional one-year period). The current monthly rent on this lease amounts to $13. During August of 2013 we also renewed our lease for our offsite warehouse in Romeoville, Illinois, through August 2016. The current monthly rent on this lease amounts to $5.

The following is a schedule of future minimum lease payments including real estate taxes as required under the above operating leases:

Year ending December 31: |  |  |  |
2015 |  | $ | 700 |
2016 |  |  | 588 |
2017 |  |  | 423 |

Rent expense, including real estate taxes, under these leases amounted to $658 and $653, for the years ended December 31, 2014 and 2013, respectively.

On December 31, 2014 equipment under capital leases had a cost of $272 with accumulated depreciation of $29. Principal and interest payments are due monthly under the capital lease obligations through November 2017. We entered into one new capital lease during November 2014 for $184 and a three year duration (through November 2017). We did not enter into any capital leases during 2013.

(7) | Accrued Expenses

Accrued expenses consist of the following:

|  | As of December 31, |
|  | 2014 |  |  | 2013 |
Accrued payroll and related expenses |  | $ | 259 |  |  | $ | 240 |
Other |  |  | 154 |  |  |  | 83 |
|  | $ | 413 |  |  | $ | 323 |

(8) | Income Taxes

We have no income tax provision, current or deferred, relating to U.S. federal, state or local income taxes.

A reconciliation of income tax expense to the amount computed by applying the Federal income tax rate to loss before provision for income taxes as of December 31, 2014 and 2013 is as follows:

|  | 2014 |  |  | 2013 |
Income tax credit at statutory rates |  | $ | (587 | ) |  | $ | (842 | )
Nondeductible expenses |  |  | 3 |  |  |  | 2 |

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of our deferred income taxes consist of the following:

|  | As of December 31, |
|  | 2014 |  |  | 2013 |
Deferred tax assets: |  |  |  |  |  |  |  |

Deferred income taxes |  | $ | — |  |  | $ | — |

The valuation allowance increased approximately $0.7 million and $1.0 million for the years ended December 31, 2014 and 2013, respectively (with no expiring net operating loss carryforwards and credits for either period; a capital loss carryforward expired during 2014) due principally to the change in the net operating loss carryforward and uncertainty as to whether future taxable income will be generated prior to the expiration of the carryforward period. Under the Internal Revenue Code, certain ownership changes, including the prior issuance of preferred stock and our public offering of common stock, may subject us to annual limitations on the utilization of our net operating loss carryforward. As of December 31, 2014, the amounts subject to limitations has not yet been determined.

We have net operating loss carryforwards for tax purposes of approximately $80 million on December 31, 2014, which expire between 2018 and 2034. We had capital loss carryforwards for tax purposes of approximately $0.3 million on December 31, 2013 which expired in 2014.

During 2011, the state of Illinois suspended the use of net operating loss carryforwards for a four year period beginning 2011, extending the term of all net loss carryforwards by a corresponding four years.

(9) | Capital Stock

As of December 31, 2014 and 2013, we had 24,088 authorized but unissued shares of preferred stock. In addition, as of December 31, 2014, 599,000 authorized but unissued shares of common stock have been reserved for future issuance upon exercise of stock options.

(10) | Stock Options and Stock Grants

We have entered into stock option agreements with certain officers, employees and directors. The stock options generally expire ten years from the date of grant.

Employee Stock Options

We follow FASB ASC Topic 718, Share-Based Payments, in which compensation expense is recognized only for share-based payments expected to vest. We recognized compensation expense related to stock options of $195 and $242 for the years ended December 31, 2014 and 2013, respectively.

As of December 31, 2014, there was approximately $229 of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted under our stock option plans. That cost is expected to be recognized over a remaining weighted-average period of 1.7 years.

##### Table of Contents

The following table illustrates the various assumptions used to calculate the Black-Scholes option pricing model for options granted for all years presented:

|  | Years Ended December 31, |
|  | 2014 |  |  | 2013 |
Weighted-average risk-free interest rates: |  |  | 2.0 | % |  |  | 1.9 | %
Dividend yield: |  |  | 0.00 | % |  |  | 0.00 | %
Weighted-average expected life of the option: |  |  | 7 years |  |  |  | 7 years |
Weighted-average expected stock price volatility: |  |  | 95 | % |  |  | 95 | %
Weighted-average fair value of the options granted: |  | $ | 0.42 |  |  | $ | 0.34 |

We use the Black-Scholes option pricing model to determine the fair value of stock based compensation. The Black-Scholes model requires us to make several assumptions, including the estimated length of time employees will retain their vested stock options before exercising them (“expected term”), the estimated volatility of our common stock price over the expected term and estimated forfeitures. Expected price volatility of the fiscal 2014 and 2013 grants is based on the daily market rate changes of our stock going back to January 1, 2006. The shares granted in fiscal 2014 and 2013 had a vesting period of three years and a contractual life of 10 years. Forfeitures were estimated at 4.0% and 4.4% for the years ended December 31, 2014 and 2013, based on our historical experience. The Black-Scholes model also requires a risk free interest rate, which is based on the U.S. Treasury yield curve in effect at the time of the grant, and the dividend yield on our common stock, which is assumed to be zero since we do not pay dividends and have no current plans to do so in the future. Changes in these assumptions can materially affect the estimate of fair value of stock based compensation and consequently, the related expense recognized on the statement of operations. We recognize stock based compensation expense on a straight-line basis.

The following table summarizes the option activity for our employees and directors during the year ended December 31, 2014:

Options |  | (rounded) Shares |  |  | Weighted Average Exercise Price per Share |  |  | Weighted Average Remaining Contractual Term (years) |  |  | Aggregate Intrinsic Value |
Outstanding on January 1, 2014 |  |  | 2,094,000 |  |  | $ | 1.30 |  |  |  |  |  |  |  |  |
Granted |  |  | 568,000 |  |  | $ | 0.52 |  |  |  |  |  |  |  |  |
Exercised |  |  | (35,000 | ) |  | $ | 0.30 |  |  |  |  |  |  |  |  |
Forfeited or expired |  |  | (187,000 | ) |  | $ | 1.20 |  |  |  |  |  |  |  |  |
Outstanding on December 31, 2014 |  |  | 2,440,000 |  |  | $ | 1.15 |  |  |  | 6.5 |  |  | $ | 45 |
Exercisable on December 31, 2014 |  |  | 1,500,000 |  |  | $ | 1.58 |  |  |  | 5.2 |  |  | $ | 30 |
Shares available for grant |  |  | 599,000 |  |  |  |  |  |  |  |  |  |  |  |  |

The aggregate intrinsic value in the table above is based on our closing stock price of $0.40 on the last business day for the year ended December 31, 2014.

During the years ended December 31, 2014 and 2013, the total intrinsic value of our stock options exercised was $4 and $3, respectively. Cash received for option exercises was $10 and $7 during the years ended December 31, 2014 and 2013, respectively. We had approximately 35,000 options exercised

F-14

##### Table of Contents

during the year ended December 31, 2014, compared to 23,000 in 2013. Based on our election of the “with and without” approach, no realized tax benefits from stock options were recognized for the years ended December 31, 2014 and 2013.

Stock Appreciation Rights

Prior to 2011, we granted our Outside Directors stock appreciation rights (SARs) under our Amended and Restated 2006 Stock Appreciation Rights Plan and subsequently under our 2010 Equity Plan. The change in fair value of the awards granted during prior years is included in non-cash compensation expense for the years ended December 31, 2014 and 2013. The SARs granted vested immediately and are payable upon the directors’ removal or resignation from the position of director. These awards are accounted for as liability awards, included in accrued expenses as of December 31, 2014 and 2013, and adjusted to fair value each reporting period. The fair value of the liability on December 31, 2014 and 2013 was $1 and $8, respectively.

Restricted Stock

As of both December 31, 2014 and 2013, we did not have any unvested non-director restricted stock or performance shares outstanding.

(11) | 401(k) Profit-Sharing Plan

We have a 401(k) profit-sharing plan covering substantially all employees who meet defined service requirements. We have made in the past, and may make in the future, maximum contributions of 100% of the first 3% and 50% of the next 2% of the participant’s salary. Our contributions under this plan were $109 for the year ended December 31, 2013. We made changes to our benefits program and, as part of those changes, discontinued these Company contributions effective January 2014, which resulted in no contributions made during 2014.

(12) | Significant Customers and Contingencies

Revenue from three customers constituted approximately 72%, 6% and 5%, respectively, of our 2014 revenue. Amounts included in accounts receivable on December 31, 2014 relating to these three customers were approximately $54, none and $47, respectively. Revenue from these three customers constituted approximately 72%, 3% and 6%, respectively, of our 2013 revenue. Amounts included in accounts receivable on December 31, 2013 relating to these three customers were approximately ($308) – customer payments in excess of outstanding volume purchase rebate, none and $46, respectively. The loss of one of these significant customers or the failure to attract new customers could have a material adverse effect on our business, results of operations and financial condition.

We currently have exclusive supply agreements with BASF Corporation (“BASF”), our largest customer, that have contingencies outlined which could potentially result in the license of technology and/or the sale of production equipment from the Company to the customer intended to provide capacity sufficient to meet the customer’s production needs. This outcome may occur if we fail to meet certain performance requirements, certain other obligations and/or certain financial condition covenants. The financial condition covenants in one of our supply agreements with BASF “trigger” a technology transfer right (license and equipment sale at BASF’s option) in the event (a) that earnings for the twelve month period ending with our most recently published quarterly financial statements are less than zero and our cash, cash equivalents and certain investments are less than $1 million, or (b) of an acceleration of any debt maturity having a principal amount of more than $10 million. Our supply agreements with BASF also “trigger” a technology transfer right in the event of our insolvency, as further defined within the agreements. In the event of an equipment sale, upon incurring a triggering event, the equipment would be sold to the customer at either 115% of the equipment’s net book value or the greater of 30% of the original book value of such equipment, and any associated upgrades to it, or 115% of the equipment’s net book value, depending on the equipment and related products.

F-15

##### Table of Contents

We believe that we have sufficient cash, (See Liquidity and Capital Resources in Management’s Discussion and Analysis in Part II, Item 7 of this Form 10-K for a further discussion) to operate our business during 2015. If a triggering event were to occur and BASF elected to proceed with the license and related equipment sale mentioned above, we would receive royalty payments from this customer for products sold using our technology; however, we would lose both significant revenue and the ability to generate significant revenue to replace that which was lost in the near term. Replacement of necessary equipment that could be purchased and removed by the customer pursuant to this triggering event could take in excess of twelve months. Any additional capital outlays required to rebuild capacity would probably be greater than the proceeds from the purchase of the assets as dictated by our agreement with the customer. Similar consequences would occur if we were determined to have materially breached certain other provisions of the supply agreement with BASF. Any such event would also likely result in the loss of many of our key staff and line employees due to economic realities. We believe that our employees are a critical component of our success and could be difficult to replace them quickly. Given the occurrence of any such event, we might not be able to hire and retain skilled employees given the stigma relating to such an event and its impact on us. Finally, any shortfall in capital needed to operate the business as management intends, including with respect to avoiding this triggering event as described above, may result in a curtailment of certain activities or anticipated investments.

(13) | Business Segmentation and Geographical Distribution

Revenue from international sources approximated $906 and $915 for the years ended December 31, 2014 and 2013, respectively. As part of our revenue from international sources, we recognized approximately $760 in product revenue from a number of German companies, in the aggregate, for the year ended December 31, 2014. Revenue from these same international sources approximated $894 for the year ended December 31, 2013.

Our operations comprise a single business segment and all of our long-lived assets are located within the United States.
