PART I


Item 1.	Business

Unless we state otherwise or the context otherwise requires, the terms "Heska," "we," "our," "us" and the "Company" refer to Heska Corporation and its consolidated subsidiaries.

Overview

We sell veterinary and animal health diagnostic and specialty products. Our offerings include point of care laboratory instruments and supplies, digital imaging products, software and services, vaccines, local and cloud-based data services, allergy testing and immunotherapy, and single-use offerings such as in-clinic diagnostic tests and heartworm preventive products. Our core focus is on the canine and feline healthcare space.

On February 24, 2013, we acquired a 54.6% interest in Cuattro Veterinary USA, LLC (the "Acquisition"), which was subsequently renamed Heska Imaging US, LLC ("US Imaging") and marked our entry into the veterinary imaging market in the United States. The remaining minority position (45.4%) in US Imaging was subject to purchase by Heska under performance-based puts and calls following the audit of our financial statements for 2016 and 2017. The required performance criteria were met in 2016, we considered notice given on March 3, 2017 that the put option was being exercised and on May 31, 2017, we delivered $13.8 million in cash to obtain the remaining minority position in US Imaging.

On May 31, 2016, we acquired Cuattro Veterinary, LLC ("Cuattro International"), which was subsequently renamed Heska Imaging International, LLC ("International Imaging") and marked our entry into the international veterinary imaging market. Financial information broken out by geographic region is incorporated by reference to Note 14 to the financial statements included under Item 8 of this annual report on

-1-

Form 10-K. As of the closing date of the Merger, the Company's interest in both International Imaging and US Imaging was transferred to the Company's wholly-owned subsidiary, Heska Imaging Global, LLC ("Global Imaging").

On June 1, 2017, the Company consolidated its assets and liabilities in the US Imaging and International Imaging companies into Global Imaging, which was re-named Heska Imaging, LLC ("Heska Imaging").

On June 13, 2017, the Company incorporated Heska Canada Limited in the province of British Columbia, in order to expand our footprint into more of the North American veterinary market.

We were founded as Paravax, Inc. and incorporated in California in 1988. We changed our name to Heska Corporation in 1995, reincorporated in Delaware and completed our initial public offering in 1997.

Our principal executive offices are located at 3760 Rocky Mountain Avenue, Loveland, Colorado 80538, our telephone number is (970) 493-7272 and our internet address is www.heska.com.

Our business is composed of two reportable segments, Core Companion Animal Health ("CCA") and Other Vaccines, Pharmaceuticals and Products ("OVP"). The CCA segment includes, primarily for canine and feline use, point of care laboratory instruments and supplies, digital imaging products, software and services, local and cloud-based data services, allergy testing and immunotherapy, and single use offerings such as point of care diagnostic tests and heartworm preventive products. The OVP segment includes private label vaccine and pharmaceutical production, primarily for cattle but also for other species including equine, porcine, avian, feline and canine. All OVP products are sold by third parties under third party labels.

Core Companion Animal Health Segment

We presently sell a variety of companion animal health products and services, among the most significant of which are the following:

Point of Care Laboratory and Imaging Diagnostics

We offer a line of veterinary point of care (stationary and portable) laboratory diagnostic instruments for testing for blood and other biological materials, for use in diagnostic imaging, and for other uses, some of which are described below. We also market and sell consumable supplies and services for these instruments. Our line of veterinary instruments includes the following:

Blood Chemistry. The Element DC^® Veterinary Chemistry Analyzer (the "Element DC") is an easy-to-use, robust system that uses dry slide technology for blood chemistry and electrolyte analysis and has the ability to run 22 tests at a time with a single blood sample. Test slides are available as both pre-packaged panels as well as individual slides. The DRI-CHEM 7000 Veterinary Chemistry Analyzer (the "DRI-CHEM 7000") is a complementary chemistry offering, co-branded with FUJIFILM Corporation ("FUJIFILM"), with higher throughput, multiple patient staging and a "STAT" feature which provides emergency sample flexibility in critical cases. The Element DC and DRI-CHEM 7000 utilize the same test slides. We are supplied with the Element DC, the DRI-CHEM 7000 and affiliated test slides and supplies under a contractual agreement with FUJIFILM.

Hematology. The Element HT5^® Hematology Analyzer (the "HT5") is a true 5-part hematology analyzer which measures key parameters such as white blood cell count, red blood cell count, platelet count

Diagnostics Data and Support. Cloudbank^TM is an automatic, secure, web-based image storage solution designed to interface with the imaging products we sell. ViewCloud^TM is a Picture Archival and Communications System (PACS) for Cloudbank for web or local viewing, reporting, planning and email sharing of studies on Internet devices, including personal computers, tablet devices and smartphones. SupportCloud^TM is a support package including call center voice and remote diagnostics, recovery and other services, such as the provision of warranty-related loaner units, to support customers. Access and operation between our imaging devices and Cloudbank and SupportCloud is supported by the acquisition software used in the equipment we sell.

With the acquisition of US Imaging and International Imaging, we entered into supply and license agreements with Cuattro to secure exclusive rights to, among other things, proprietary acquisition software, Cloudbank, ViewCloud, research and development, and other benefits. Cuattro provides us with much of the hardware, software, data hosting and other services for our digital radiography solutions under these exclusive contractual arrangements. Cuattro is 100% owned by our President and Chief Executive Officer, Kevin S. Wilson, his spouse, Shawna M. Wilson ("Mrs. Wilson") and by trusts for the benefit of their children and family.

Point-of-Care Heartworm Diagnostic Tests

Heartworm infections of dogs and cats are caused by the parasite Dirofilaria immitis. This parasitic worm is transmitted in larval form to dogs and cats through the bite of an infected mosquito. Larvae develop into adult worms that live in the pulmonary arteries and heart of the host, where they can cause serious cardiovascular, pulmonary, liver and kidney disease. Our canine and feline heartworm diagnostic tests use monoclonal antibodies or a recombinant heartworm antigen, respectively, to detect heartworm antigens or antibodies circulating in the blood of an infected animal.

We market and sell heartworm diagnostic tests for both canine and feline species. SOLO STEP CH for dogs and SOLO STEP FH for cats are available in point-of-care, single use formats that can be used by veterinarians on site. We also offer SOLO STEP CH Batch Test Strips, a rapid and simple point-of-care antigen detection test for dogs that allows veterinarians in larger practices to run multiple samples at the same time. We obtain SOLO STEP CH, SOLO STEP FH and SOLO STEP Batch Test Strips under a contractual agreement with Quidel Corporation ("Quidel").

Heartworm Preventive Products

We have an agreement with Merck Animal Health, a unit of Merck & Co., Inc., granting Merck Animal Health the exclusive distribution and marketing rights for our canine heartworm prevention product, TRI-HEART Plus Chewable Tablets, ultimately sold to or through veterinarians in the United States and Canada. TRI-HEART Plus Chewable Tablets (ivermectin/pyrantel) are indicated for use as a monthly preventive treatment of canine heartworm infection and for treatment and control of ascarid and hookworm infections. We manufacture TRI-HEART Plus Chewable Tablets at our Des Moines, Iowa production facility.

Allergy Products and Services

Allergy is common in companion animals, and it has been estimated to affect approximately 10% to 15% of dogs. Clinical symptoms of allergy are variable, but are often manifested as persistent and serious skin disease in dogs and cats. Clinical management of allergic disease is problematic, as there are a large number of allergens that may give rise to these conditions. Although skin testing is often regarded as the most accurate diagnostic procedure, such tests can be painful, subjective and inconvenient. The effectiveness of the immunotherapy that is prescribed to treat symptoms of allergic disease is inherently limited by inaccuracies in the diagnostic process.

-4-

We believe that our ALLERCEPT Definitive Allergen Panels provide the most accurate determination of which we are aware of the specific allergens to which an animal, such as a dog, cat or horse, is reacting. The panels use a highly specific recombinant version of the natural IgE receptor to test the serum of potentially allergic animals for IgE directed against a panel of known allergens. A typical test panel consists primarily of various pollen, grass, mold, insect and mite allergens. The test results serve as the basis for prescription ALLERCEPT Therapy Shots and ALLERCEPT Therapy Drops. We operate veterinary laboratories in Loveland, Colorado and Fribourg, Switzerland which both offer blood testing using our ALLERCEPT Definitive Allergen Panels.

We sell kits to conduct blood testing using our ALLERCEPT Definitive Allergen Panels to third-party veterinary diagnostic laboratories outside of the United States. We also sell products to screen for the presence of allergen-specific IgE to these customers - we sell kits to conduct preliminary blood testing using products based on our ALLERCEPT Definitive Allergen Panels as well as a similar test requiring less technical sophistication, our E-SCREEN Test. Animals testing positive for allergen-specific IgE using these screening tests are candidates for further evaluation using our ALLERCEPT Definitive Allergen Panels.

Veterinarians who use our ALLERCEPT Definitive Allergen Panels often purchase our ALLERCEPT Therapy Shots or ALLERCEPT Therapy Drops. These prescription immunotherapy treatment sets are formulated specifically for each allergic animal and contain only the allergens to which the animal has significant levels of IgE antibodies. The prescription formulations are administered in a series of subcutaneous injections (Shots) or by daily sublingual (under the tongue) administration (Drops), with doses increasing over several months, to ameliorate the allergic condition of the animal. Immunotherapy is generally continued for an extended time. We offer canine, feline and equine subcutaneous and sublingual immunotherapy treatment products. We believe our ALLERCEPT Therapy Drops offer a convenient alternative to subcutaneous injection, thereby increasing the likelihood of pet owner compliance.

Total assets of the CCA segment were $112 million, $111 million, $93 million as of December 31, 2017, 2016, and 2015, respectively. See Item 7 - MDA for Results of Operations for the CCA segment.

Other Vaccines, Pharmaceuticals and Products Segment

We developed a line of bovine vaccines that are licensed by the United States Department of Agriculture ("USDA"). Historically, the largest distributor of these vaccines was Agri Laboratories, Ltd. ("AgriLabs"), who sold these vaccines primarily under the Titanium® and MasterGuard® brands. In November 2013, Agrilabs assigned the long-term agreement with us related to these vaccines to, and the agreement was assumed by, Eli Lilly and Company ("Eli Lilly") acting through Elanco. In January 2015, we signed a long-term Master Supply Agreement related to these vaccines with Eli Lilly acting through Elanco, thereby terminating the AgriLabs agreement previously assumed by Eli Lilly in November 2013.

We manufacture biological and pharmaceutical products for a number of other animal health companies. We manufacture products for animals other than cattle including horses, pigs, chickens, cats and dogs. Our offerings range from providing complete turnkey services which include research, licensing, production, labeling and packaging of products to providing any one of these services as needed by our customers as well as validation support and distribution services.

Total assets of the OVP segment were $24 million, $20 million, $17 million as of December 31, 2017, 2016, and 2015, respectively. See Item 7 - MDA for Results of Operations for the OVP segment.

Marketing, Sales and Customer Support

We currently market our Core Companion Animal Health products in the United States to veterinarians through an outside field organization, a telephone sales force, independent third-party distributors, as well as through trade shows and print advertising and through other distribution relationships, such as Merck Animal Health in the case of our heartworm preventive. As of December 31, 2017, our customer facing sales, installed base support and utilization organization consisted of 82 individuals in various parts of the United States.

Veterinarians may obtain our products directly from us or indirectly through others. All of our Core Companion Animal Health products ultimately are sold primarily to or through veterinarians. The acceptance of our products by veterinarians is critical to our success.

We have a staff dedicated to customer and product support in our Core Companion Animal Health segment including veterinarians, technical support specialists and service technicians. Individuals from our product development group may also be used as a resource in responding to certain product inquiries.

Internationally, we market our Core Companion Animal Health products to veterinarians primarily through third-party veterinary diagnostic laboratories and independent third-party distributors.

All OVP products are marketed and sold by third parties under third-party labels.

We grant third parties rights to our intellectual property as well as our products, with our compensation often taking the form of royalties and/or milestone payments.

Manufacturing

The majority of our revenue is from proprietary products manufactured by third parties. Third parties manufacture our veterinary instruments, including affiliated consumables and supplies, as well as other products including key components of our heartworm point-of-care diagnostic tests. We manufacture and supply Quidel with certain critical raw materials and perform the final packaging operations for these products.

Our facility in Des Moines, Iowa is a United States Department of Agriculture ("USDA"), Food and Drug Administration ("FDA"), and Drug Enforcement Agency ("DEA") licensed biological and pharmaceutical manufacturing facility. This facility currently has the capacity to manufacture more than 50 million doses of vaccine each year. We expect that we will, for the foreseeable future, manufacture most or all of our pharmaceutical and biological products at this facility, as well as most or all of our recombinant proteins and other proprietary reagents for our diagnostic tests. We currently manufacture our canine heartworm prevention product, our allergy treatment products and all our OVP segment products at this facility. The OVP segment's customers purchase products in both finished and bulk format, and we perform all phases of manufacturing, including growth of the active bacterial and viral agents, sterile filling, lyophilization and packaging at this facility. We manufacture our various allergy products at our Des Moines facility, our Loveland facility and our Fribourg facility. We believe the raw materials for products we manufacture are readily available from more than one source.

-6-

Product Development

We are committed to providing innovative products to address health needs of companion animals. We may obtain such products from external sources, external collaboration or internal research and development.

We are committed to identifying external product opportunities and creating business and technical collaborations that lead to high value veterinary products. We believe that our active participation in scientific networks and our reputation for investing in research enhances our ability to acquire external product opportunities. We have collaborated, and intend to continue to do so, with a number of companies and universities. Examples of such collaborations include:


•	Quidel for the development of SOLO STEP CH Cassettes, SOLO STEP CH Batch Test Strips and SOLO STEP FH Cassettes;


•	Mindray for the development of veterinary applications for the HT5 Veterinary Hematology Analyzer and associated reagents;


•	FUJIFILM for the development of veterinary applications for the Element DC Veterinary Chemistry Analyzer and associated slides and supplies; and


•	Cuattro for the development of veterinary applications for digital imaging and data hosting.

Internal research and development is managed on a case-by-case basis. We employ individuals with expertise in various applicable areas and will form multidisciplinary product-associated teams as appropriate. We incurred expenses of $2.0 million, $2.1 million and $1.7 million in the years ended December 31, 2017, 2016 and 2015, respectively, in support of our research and development activities.

Intellectual Property

We believe that patents, trademarks, copyrights and other proprietary rights represent opportunities to grow our business and maintain or enhance our competitive position. We also rely upon trade secrets, know-how, continuing technological innovations and licensing opportunities to develop and maintain our competitive position. The proprietary technologies of our OVP segment are primarily protected through trade secret protection of, for example, our manufacturing processes in this area.

We actively seek patent protection both in the United States and abroad. Our issued patent portfolios primarily relate to heartworm control, flea control, allergy, infectious disease vaccines, diagnostic and detection tests, immunomodulators, instrumentation, nutrition, pain control and vaccine delivery technologies. As of December 31, 2017, we owned, co-owned or had rights to 68 issued US patents expiring at various dates from January 2018 to May 2028 and had no pending US patent applications. Our corresponding foreign patent portfolio as of December 31, 2017 included 62 issued patents in various foreign countries expiring at various dates from January 2019 to August 2024 and had no pending applications.

We also have obtained exclusive and non-exclusive licenses for numerous other patents held by academic institutions and for profit companies.

Seasonality

Our fourth quarter results in any given year are typically stronger than those for any other quarter. We expect this trend to continue in the future as it is a long term trend within our imaging diagnostic business.

-7-

Government Regulation

Although the majority of our revenue is from the sale of unregulated items, many of our products or products that we may develop are, or may be, subject to extensive regulation by governmental authorities in the United States, including the USDA and the FDA, and by similar agencies in other countries. These regulations govern, among other things, the development, testing, manufacturing, labeling, storage, pre-market approval, advertising, promotion, sale and distribution of our products. Satisfaction of these requirements can take several years to achieve and the time needed to satisfy them may vary substantially, based on the type, complexity and novelty of the product. Any product that we develop must receive all relevant regulatory approval or clearances, if required, before it may be marketed in a particular country. The following summarizes the major US government agencies that regulate animal health products:

•

USDA. Vaccines and certain single use, point-of-care diagnostics are considered veterinary biologics and are therefore regulated by the Center for Veterinary Biologics, or CVB, of the USDA. Industry data indicates that it takes approximately five to seven years and in excess of $2.0 - $5.0 million to license a conventional vaccine for animals from basic research through licensing. In contrast to vaccines, single use, point-of-care diagnostics can typically be licensed by the USDA in about two years, at considerably less cost. However, vaccines or diagnostics that use innovative materials, such as those resulting from recombinant DNA technology, usually require additional time to license. The USDA licensing process involves the submission of several data packages. These packages include information on how the product will be manufactured, information on the efficacy and safety of the product in laboratory and target animal studies and information on performance of the product in field conditions.

•

FDA. Pharmaceutical products, which typically include synthetic compounds, are approved and monitored by the Center for Veterinary Medicine of the FDA. Under the Federal Food, Drug and Cosmetic Act, the same statutory standard for FDA approval applies to both human and animal drugs: demonstrated safety, efficacy and compliance with FDA manufacturing standards. However, unlike human drugs, neither preclinical studies nor a sequential phase system of studies are required. Rather, for animal drugs, studies for safety and efficacy may be conducted immediately in the species for which the drug is intended. Thus, there is no required phased evaluation of drug performance, and the Center for Veterinary Medicine will review data at appropriate times in the drug development process. The process can be costly and time consuming, requiring up to $100 million and seven to ten years to sell an animal drug in the market. In addition, the time and cost for developing companion animal drugs may be significantly less than for drugs for livestock animals, which generally have enhanced standards designed to ensure safety in the food chain.


•	EPA. Products that are applied topically to animals or to premises to control external parasites are regulated by the Environmental Protection Agency, or EPA.

After we have received regulatory licensing or approval for our products, numerous regulatory requirements typically apply. Among the conditions for certain regulatory approvals is the requirement that our manufacturing facilities or those of our third-party manufacturers conform to current Good Manufacturing Practices or other manufacturing regulations, which include requirements relating to quality control and quality assurance as well as maintenance of records and documentation. The USDA, FDA and foreign regulatory authorities strictly enforce manufacturing regulatory requirements through periodic inspections and/or reports.

-8-

A number of our animal health products are not regulated. For example, certain products such as our ALLERCEPT panels are not regulated by either the USDA or FDA. Similarly, none of our veterinary instruments requires regulatory approval to be marketed and sold in the United States.

We have pursued CE mark for imaging equipment and regulatory approval outside the United States based on market demographics of foreign countries. For marketing outside the United States, we are subject to foreign regulatory requirements governing regulatory licensing and approval for many of our products. Licensing and approval by comparable regulatory authorities of foreign countries must be obtained before we can market products in those countries. Product licensing approval processes and requirements vary from country to country and the time required for such approvals may differ substantially from that required in the United States. We cannot be certain that approval of any of our products in one country will result in approvals in any other country.

To date, we or our distributors have sought regulatory approval for certain of our products in Canada, which is governed by the Canadian Center for Veterinary Biologics, or CCVB; in Japan, which is governed by the Japanese Ministry of Agriculture, Forestry and Fisheries, or MAFF; in Australia, which is governed by the Australian Department of Agriculture, Fisheries and Forestry, or ADAFF; in South Africa, which is governed by the Republic of South Africa Department of Agriculture, or RSADA; in Hong Kong, which is governed by the Agriculture, Fisheries and Conservation Department, or ADCD; in Macau, which is governed by the Macau Animal Health Division of Animal Control and Inspection, or IACM; and in certain other countries requiring such approval.

Core Companion Animal Health products previously discussed which have received regulatory approval in the United States and/or elsewhere are summarized below:

Competition

Our market is intensely competitive. Our competitors include independent animal health companies and major pharmaceutical companies that have animal health divisions. We also compete with independent, third-party distributors, including distributors who sell products under their own private labels. In the point of care diagnostic testing market, our major competitors include IDEXX Laboratories, Inc. ("IDEXX"), Abaxis, Inc. ("Abaxis") and Zoetis Inc. ("Zoetis"). The products manufactured by our OVP segment for sale by third parties compete with similar products offered by a number of other companies, some of which have substantially greater financial, technical, research and other resources than us and may have more established marketing, sales, distribution and service organizations than our OVP segment's customers. Companies with a significant presence in the animal health market such as Bayer AG, CEVA Santé Animale, Eli Lilly, Merck, Sanofi, Vétoquinol S.A., Virbac S.A. and Zoetis may be marketing or developing products that compete with our products or would compete with them if successfully developed. These and other competitors and potential competitors may have substantially greater financial, technical, research and other resources and larger, more established marketing, sales, distribution and service organizations than we do. Our competitors may offer broader product lines and have greater name recognition than we do.

Environmental Regulation

In connection with our product development activities and manufacturing of our biological, pharmaceutical and diagnostic and detection products, we are subject to federal, state and local laws, rules, regulations and policies governing the use, generation, manufacture, storage, handling and disposal of certain materials, biological specimens and wastes. Although we believe that we have complied with these laws, regulations and policies in all material respects and have not been required to take any significant action to correct any noncompliance, we may be required to incur significant costs to comply with environmental and health and safety regulations in the future. Although we believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by state and federal regulations, the risk of accidental contamination or injury from these materials cannot be eliminated. In the event of such an accident, we could be held liable for any damages that result and any such liability could exceed our resources.

Employees

As of March 8, 2018, we and our subsidiaries employed 345 people. None of our employees are covered by a collective bargaining agreement, and we believe our employee relations are good.

Item 1A.	Risk Factors

Our future operating results may vary substantially from period to period due to a number of factors, many of which are beyond our control. The following discussion highlights some of these factors and the possible impact of these factors on future results of operations. The risks and uncertainties described below are not the only ones we face. Additional risks or uncertainties not presently known to us or that we deem to be currently immaterial also may impair our business operations. If any of the following factors actually occur, our business, financial condition or results of operations could be harmed. In that case, the price of our Public Common Stock could decline and investors in our Public Common Stock could experience losses on their investment.

We have significant related party transactions.

Cuattro, LLC is a supplier to Heska Imaging, LLC under an Amended and Restated Master License Agreement and Supply Agreement which was negotiated at arm's length as part of the acquisition by Heska Corporation of a majority interest in a predecessor entity to Heska Imaging, LLC. As discussed below, Mr. Wilson has an interest in these agreements and any time and resources devoted to monitoring and overseeing this relationship may prevent us from deploying such time and resources on more productive matters.

Mr. Wilson's employment agreement with us acknowledges that Mr. Wilson has business interests in Cuattro, LLC, Cuattro Software, LLC and Cuattro Medical, LLC which may require a portion of his time, resources and attention in his working hours. If Mr. Wilson is distracted by these or other business interests, he may not contribute as much as he otherwise would have to enhancing our business, to the detriment of our shareholder value. Mr. Wilson is the spouse of Shawna M. Wilson ("Mrs. Wilson"). Mr. Wilson, Mrs. Wilson and trusts for their children and family own a majority interest in Cuattro Medical, LLC. In addition, including equity held by Mrs. Wilson and by trusts for the benefit of Mr. and Mrs. Wilson's children and family, Mr. Wilson also owns a 100% interest in Cuattro, LLC, the largest supplier to Heska Imaging, LLC, our wholly-owned subsidiary. Cuattro, LLC owns a 100% interest in Cuattro Software, LLC.

Cuattro, LLC charged Heska Imaging $17.7 million, $14.5 million, and $9.0 million during 2017, 2016, and 2015, respectively, primarily related to digital imaging products, for which there is an underlying supply contract with minimum purchase obligations, software and services as well as other operating expenses. Heska Corporation charged Cuattro, LLC $0.1 million, $0.2 million, and $0.2 million in the years ended December 31, 2017, 2016, and 2015, respectively, primarily related to facility usage and other services.

Heska Corporation had a receivable from Cuattro, LLC of $1 thousand and $22 thousand as of December 31, 2017 and 2016, respectively which is included in "Due from - related parties" on the Company's consolidated balance sheet. Heska Imaging, LLC had a receivable from Cuattro, LLC of $0 thousand and $78 thousand as of December 31, 2017 and 2016, respectively. Heska Imaging, LLC owed Cuattro $1.7 million as of December 31, 2017, and Global Imaging owed Cuattro $1.6 million as of December 31, 2016, which is included in "Due to- related parties" on the Company's consolidated balance sheets.

We may face costly legal disputes, including disputes related to our intellectual property or technology or that of our suppliers or collaborators.

We may face legal disputes related to our business. For example, on March 12, 2015, a complaint was filed against us by Shaun Fauley in the United States District Court Northern District of Illinois alleging our transmittal of unauthorized faxes in violation of the federal Telephone Consumer Protection Act of 1991, as amended by the Junk Fax Prevention Act of 2005, as a class action seeking stated damages of the greater of actual monetary loss or five hundred dollars per violation ("Fauley Complaint"). Even if meritless, these

-13-

disputes may require significant expenditures on our part and could entail a significant distraction to members of our management team or other key employees. Insurance coverage may not cover any costs required to litigate a legal dispute or an unfavorable ruling or settlement. We do not have insurance coverage for the Fauley Complaint. A legal dispute leading to an unfavorable ruling or settlement, whether or not insurance coverage may be available for any portion thereof, could have significant material adverse consequences on our business. We may have to use legal means and incur affiliated costs to secure the benefits to which we are entitled, such as to collect payment for goods shipped to third parties, which would reduce our income as compared to what it otherwise would have been.

We may become subject to patent infringement claims and litigation in the United States or other countries or interference proceedings conducted in the United States Patent and Trademark Office, or USPTO, to determine the priority of inventions. The defense and prosecution of intellectual property suits, USPTO interference proceedings and related legal and administrative proceedings are likely to be costly, time-consuming and distracting. As is typical in our industry, from time to time we and our collaborators and suppliers have received, and may in the future receive, notices from third parties claiming infringement and invitations to take licenses under third-party patents. Any legal action against us or our collaborators or suppliers may require us or our collaborators or suppliers to obtain one or more licenses in order to market or manufacture effected products or services. However, we or our collaborators or suppliers may not be able to obtain licenses for technology patented by others on commercially reasonable terms, or at all, or to develop alternative approaches to access or replace such technology if unable to obtain licenses or current and future licenses may not be adequate, any of which could substantially harm our business.

We may also need to pursue litigation to enforce any patents issued to us or our collaborative partners, to protect trade secrets or know-how owned by us or our collaborative partners, or to determine the enforceability, scope and validity of the proprietary rights of others. Any litigation or interference proceedings will likely result in substantial expense to us and significant diversion of the efforts of our technical and management personnel. Any adverse determination in litigation or interference proceedings could subject us to significant liabilities to third parties. Further, as a result of litigation or other proceedings, we may be required to seek licenses from third parties which may not be available on commercially reasonable terms, if at all.

If the third parties who have substantial marketing rights for certain of our historical products, existing products or future products under development are not successful in marketing those products, then our sales and financial position may suffer.

We are party to an agreement with Merck Animal Health, which grants Merck Animal Health exclusive distribution and marketing rights for our canine heartworm preventive product, TRI-HEART Plus Chewable Tablets, ultimately sold to or through veterinarians in the United States and Canada. Historically, a significant portion of our OVP segment's revenue has been generated from the sale of certain bovine vaccines, which have been sold primarily under the Titanium® and MasterGuard® brands. We have a supply agreement with Eli Lilly and its affiliates operating through Elanco for the production of these vaccines. Either of these marketing partners may not devote sufficient resources to marketing our products and our sales and financial position could suffer significantly as a result. Revenue from Merck & Co., Inc. ("Merck") entities, including Merck Animal Health, represented 12% of our 2017 revenue. Revenue from Eli Lilly entities, including Elanco, represented 11% of our 2017 revenue. If Merck Animal Health personnel fail to market, sell and support our heartworm preventive sufficiently or if Elanco personnel fail to market, sell and support the bovine vaccines we produce and sell to Elanco sufficiently, our sales could decline significantly. Furthermore, there may be nothing to prevent these partners from pursuing alternative technologies, products or supply arrangements, including as part of mergers, acquisitions or divestitures. For example, we believe a unit of Merck has obtained FDA approval for a canine heartworm preventive product with additional claims

-14-

compared with our TRI-HEART Plus Chewable Tablets, but which we believe is not currently being marketed actively. Should Merck decide to emphasize sales and marketing efforts of this product rather than our TRI-HEART Plus Chewable Tablets or cancel our agreement regarding canine heartworm preventive distribution and marketing, our sales could decline significantly. In another example, if Elanco were to emphasize sales and marketing efforts for bovine vaccines other than those we produce or cancel our supply agreement and produce the vaccines we supply to it by itself, our sales could decline significantly. Third-party marketing assistance may not be available in the future on reasonable terms, if at all. If the third parties with marketing rights for our products were to merge or go out of business, the sale and promotion of our products could be diminished.

We rely substantially on third-party suppliers. The loss of products or delays in product availability from one or more third-party suppliers could substantially harm our business.

To be successful, we must contract for the supply of, or manufacture ourselves, current and future products of appropriate quantity, quality and cost. Such products must be available on a timely basis and be in compliance with any regulatory requirements. Similarly, we must provide ourselves, or contract for the supply of, certain services. Such services must be provided in a timely and appropriate manner. Failure to do any of the above could substantially harm our business.

We rely on third-party suppliers to manufacture those products we do not manufacture ourselves and to provide services we do not provide ourselves. Proprietary products provided by these suppliers represent a majority of our revenue. We currently rely on these suppliers for our point of care laboratory instruments and consumable supplies for these instruments, for our imaging products and related software and services, for key components of our point-of-care diagnostic tests as well as for the manufacture of other products.

The loss of access to products from one or more suppliers could have a significant, negative impact on our business. Major suppliers who sell us proprietary products who are responsible for more than 5% of our LTM revenue are FUJIFILM Corporation, Cuattro, LLC, and Shenzen Mindray Bio-Medical Electronics Co., Ltd. Only FUJIFILM Corporation sold us products that were responsible for more than 25% of our LTM revenue. We often purchase products from our suppliers under agreements that are of limited duration or potentially can be terminated on an annual basis. In the case of our point of care laboratory instruments and our digital radiography solutions, post-termination, we are typically entitled to non-exclusive access to consumable supplies, or ongoing non-exclusive access to products and services to meet the needs of an existing customer base, respectively, for a defined period upon expiration of exclusive rights, which could subject us to competitive pressures in the period of non-exclusive access. Although we believe we will be able to maintain a supply of our major product and service offerings in the near future, there can be no assurance that our suppliers will meet their obligations under any agreements we may have in place with them or that we will be able to compel them to do so. Risks of relying on suppliers include:

•

Inability to meet minimum obligations. Current agreements, or agreements we may negotiate in the future, may commit us to certain minimum purchase or other spending obligations. It is possible we will not be able to create the market demand to meet such obligations, which could create a drain on our financial resources and liquidity. Some such agreements may require minimum purchases and/or sales to maintain product rights and we may be significantly harmed if we are unable to meet such requirements and lose product rights.

•

Loss of exclusivity. In the case of our point of care laboratory instruments, if we are entitled to non-exclusive access to consumable supplies for a defined period upon expiration of exclusive rights, we may face increased competition from a third party with similar non-exclusive access or our former supplier, which could cause us to lose customers and/or significantly decrease our margins and could significantly affect our financial results. In addition, current agreements, or

-15-

agreements we may negotiate in the future, with suppliers may require us to meet minimum annual sales levels to maintain our position as the exclusive distributor of these products. We may not meet these minimum sales levels and maintain exclusivity over the distribution and sale of these products. If we are not the exclusive distributor of these products, competition may increase significantly, reducing our revenues and/or decreasing our margins.


•	Changes in economics. An underlying change in the economics with a supplier, such as a large price increase or new requirement of large minimum purchase amounts, could have a significant, adverse effect on our business, particularly if we are unable to identify and implement an alternative source of supply in a timely manner.

•

The loss of product rights upon expiration or termination of an existing agreement. Unless we are able to find an alternate supply of a similar product, we would not be able to continue to offer our customers the same breadth of products and our sales and operating results would likely suffer. In the case of an instrument supplier, we could also potentially suffer the loss of sales of consumable supplies, which would be significant in cases where we have built a significant installed base, further harming our sales prospects and opportunities. Even if we were able to find an alternate supply for a product to which we lost rights, we would likely face increased competition from the product whose rights we lost being marketed by a third party or the former supplier and it may take us additional time and expense to gain the necessary approvals and launch an alternative product.

•

High switching costs. In our point of care laboratory instrument products, we could face significant competition and lose all or some of the consumable revenues from the installed base of those instruments if we were to switch to a competitive instrument. If we need to change to other commercial manufacturing contractors for certain of our regulated products, additional regulatory licenses or approvals generally must be obtained for these contractors prior to our use. This would require new testing and compliance inspections prior to sale, thus resulting in potential delays. Any new manufacturer would have to be educated in, or develop, substantially equivalent processes necessary for the production of our products. We likely would have to train our sales force, distribution network employees and customer support organization on the new product and spend significant funds marketing the new product to our customer base.

•

The involuntary or voluntary discontinuation of a product line. Unless we are able to find an alternate supply of a similar product in this or similar circumstances with any product, we would not be able to continue to offer our customers the same breadth of products and our sales would likely suffer. Even if we are able to identify an alternate supply, it may take us additional time and expense to gain the necessary approvals and launch an alternative product, especially if the product is discontinued unexpectedly.


•	Inconsistent or inadequate quality control. We may not be able to control or adequately monitor the quality of products we receive from our suppliers. Poor quality items could damage our reputation with our customers.

•

Limited capacity or ability to scale capacity. If market demand for our products increases suddenly, our current suppliers might not be able to fulfill our commercial needs, which would require us to seek new manufacturing arrangements and may result in substantial delays in meeting market demand. If we consistently generate more demand for a product than a given supplier is capable of handling, it could lead to large backorders and potentially lost sales to competitive products that are readily available. This could require us to seek or fund new sources of supply, which may be difficult to find or may require terms that are less advantageous if available at all.

-16-

•

Regulatory risk. Our manufacturing facility and those of some of our third-party suppliers are subject to ongoing periodic unannounced inspection by regulatory authorities, including the FDA, USDA and other federal, state and foreign agencies for compliance with strictly enforced Good Manufacturing Practices, regulations and similar foreign standards. We do not have control over our suppliers' compliance with these regulations and standards. Regulatory violations could potentially lead to interruptions in supply that could cause us to lose sales to readily available competitive products. If one of our suppliers is unable to provide a raw material or finished product due to regulatory issues, it could have a material adverse financial impact on our business and could expose us to legal action if we are unable to perform on contracts to our customers involving related products.


•	Developmental delays. We may experience delays in the scale-up quantities needed for product development that could delay regulatory submissions and commercialization of our products in development, causing us to miss key opportunities.

•

Limited geographic rights. We typically do not have global geographic rights to products supplied by third parties. If we were to determine a market opportunity in a geography where we did not have distribution rights and were unable to obtain such rights from the supplier, it might hamper our ability to succeed in such geography and our sales and profits would be lower than they otherwise would have been.


•	Limited intellectual property rights. We typically do not have intellectual property rights, or may have to share intellectual property rights, to the products supplied by third parties and any improvements to the manufacturing processes or new manufacturing processes for these products.

Potential problems with suppliers such as those discussed above could substantially decrease sales, lead to higher costs and/or damage our reputation with our customers due to factors such as poor quality goods or delays in order fulfillment, resulting in our being unable to sell our products effectively and substantially harming our business.

The loss of significant customers who, for example, are historically large purchasers or who are considered leaders in their field could damage our business and financial results.

In our CCA Segment, revenue from Butler Animal Health Supply, LLC d/b/a Henry Schein Animal Health ("Henry Schein") represented approximately 13%, 13%, and 10% of our consolidated revenue for the years ended December 31, 2017, 2016, and 2015, respectively. Revenue from Merck entities, including Merck Animal Health, represented approximately 12% for the year ended December 31, 2017, and 11% each for the years ended December 31, 2016 and 2015. Revenue from De Lage Landen Financial Services, Inc. ("DLL"), represented approximately 7%, 11%, and 10% of our consolidated revenue for the years ended December 31, 2017, 2016, and 2015, respectively. DLL is a third-party financing company that provides financing and leasing for, primarily, our imaging product customers. In our OVP segment, revenue from Eli Lilly entities, including Elanco, represented approximately 11%, 12% and 12% for the years ended December 31, 2017, 2016, and 2015, respectively. No other customer accounted for more than 10% of our consolidated revenue for the years ended December 31, 2017, 2016, or 2015.

Henry Schein represented 16% of our consolidated accounts receivable at December 31, 2017 and 2016. Merck entities represented approximately 15% and 11% of our consolidated accounts receivable at December 31, 2017 and 2016, respectively. DLL represented 11% and 18% of our consolidated accounts receivable at December 31, 2017 and 2016, respectively. Eli Lilly entities, including Elanco, represented approximately 3% and 15% of our consolidated accounts receivable at December 31, 2017 and 2016, respectively. No other customer accounted for more than 10% of our consolidated accounts receivable at December 31, 2017 or 2016.

-17-

The loss of significant customers who, for example, are historically large purchasers or who are considered leaders in their field could damage our business, reputation, and financial results.

We operate in a highly competitive industry, which could render our products obsolete or substantially limit the volume of products that we sell. This would limit our ability to compete and maintain sustained profitability.

The market in which we compete is intensely competitive. Our competitors include independent animal health companies and major pharmaceutical companies that have animal health divisions. We also compete with independent, third-party distributors, including distributors who sell products under their own private labels. In the point-of-care diagnostic testing market, our major competitors include IDEXX Laboratories, Inc. ("IDEXX"), Abaxis Inc. ("Abaxis"), and Zoetis Inc. ("Zoetis"). The products manufactured by our OVP segment for sale by third parties compete with similar products offered by a number of other companies, some of which have substantially greater financial, technical, research and other resources than us and may have more established marketing, sales, distribution and service organizations than those of our OVP segment customers. Competitors may have facilities with similar capabilities to our OVP segment, which they may operate and sell at a lower unit price to customers than our OVP segment does, which could cause us to lose customers. Companies with a significant presence in the companion animal health market, such as Bayer AG, CEVA Santé Animale, Eli Lilly, Merck, Sanofi, Vétoquinol S.A. and Virbac S.A. may be marketing or developing products that compete with our products or would compete with them if developed. These and other competitors and potential competitors may have substantially greater financial, technical, research and other resources and larger, more established marketing, sales and service organizations than we do. For example, if Zoetis devotes its significant commercial and financial resources to growing its market share in the veterinary allergy market, our allergy-related sales could suffer significantly. Our competitors may offer broader product lines and have greater name recognition than we do. Our competitors may also develop or market technologies or products that are more effective or commercially attractive than our current or future products or that would render our technologies and products obsolete. Further, additional competition could come from new entrants to the animal health care market. Moreover, we may not have the financial resources, technical expertise or marketing, sales or support capabilities to compete successfully. Zoetis has recently launched allergy products which may diminish the competitiveness and sales prospects for our own allergy immunotherapy products. IDEXX has recently launched an SDMA test in its point of care laboratory chemistry line, which may cause veterinary customers to prefer IDEXX products to ours.

If we fail to compete successfully, our ability to achieve sustained profitability will be limited and sustained profitability, or profitability at all, may not be possible.

We benefit from relationships or collaboration with third parties, including but not limited to, companies, buying groups, veterinary hospital groups, and reference laboratory entities that operate in our markets. Beneficial third party, semi-competitive, directly competitive, and cooperative relationships that affect how we go to market, develop products, generate leads, and other commercial efforts of Heska may be negatively affected as a result of consolidation, acquisition, merger, exclusive arrangement, or other agreements or activities between and amongst those third parties and others.

We depend on key personnel for our future success. If we lose our key personnel or are unable to attract and retain additional personnel, we may be unable to achieve our goals.

Our future success is substantially dependent on the efforts of our senior management and other key personnel, including our Chief Executive Officer and President, Kevin Wilson. The loss of the services of members of our senior management or other key personnel may significantly delay or prevent the achievement of our business objectives. Although we have employment agreements with many of these individuals, all are at-will employees, which means that either the employee or Heska may terminate employment at any time without prior notice. If we lose the services of, or fail to recruit, key personnel, the growth of our business could be substantially impaired. We do not maintain key person life insurance for any of our senior management or key personnel.

We often depend on third parties for products we intend to introduce in the future. If our current relationships and collaborations are not successful, we may not be able to introduce the products we intend to introduce in the future.

We are often dependent on third parties and collaborative partners to successfully and timely perform research and development activities to successfully develop new products. We routinely discuss Heska marketing in the veterinary market instruments being developed by third parties for use in the human health care market. In the future, one or more of these third parties or collaborative partners may not complete research and development activities in a timely fashion, or at all. Even if these third parties are successful in their research and development activities, we may not be able to come to an economic agreement with them. If these third parties or collaborative partners fail to complete research and development activities or fail to complete them in a timely fashion, or if we are unable to negotiate economic agreements with such third parties or collaborative partners, our ability to introduce new products will be impacted negatively and our revenues may decline.

We may be unable to market and sell our products successfully.

We may not develop and maintain marketing and/or sales capabilities successfully, and we may not be able to make arrangements with third parties to perform these activities on satisfactory terms. If our marketing and sales strategy is unsuccessful, our ability to sell our products will be negatively impacted and our revenues will decrease. This could result in the loss of distribution rights for products or failure to gain access to new products and could cause damage to our reputation and adversely affect our business and future prospects.

The market for companion animal healthcare products is highly fragmented. Because our CCA proprietary products are generally available only to veterinarians or by prescription and our medical instruments require technical training to operate, we ultimately sell all our CCA products primarily to or through veterinarians. The acceptance of our products by veterinarians is critical to our success. Changes in our ability to obtain or maintain such acceptance or changes in veterinary medical practice could significantly decrease our anticipated sales. As the vast majority of cash flow to veterinarians ultimately is funded by pet owners without private insurance or government support, our business may be more susceptible to severe economic downturns than other health care businesses which rely less on individual consumers.

For our point of care laboratory blood diagnostics products, we primarily rely on contracts with our veterinary customers for their use of our owned equipment and our consumables supplies over a multiple year period. If veterinarians under these contracts experience a significant downturn in their business, they may not fulfill their use and financial obligations under these contracts. If veterinarians breach our contracts, and we are unable to collect on default payment provisions or otherwise enforce the terms of our contracts, our business will be adversely affected. If we have to litigate against customer(s) to enforce our contracts, our

-19-

expenses may increase, our sales may decrease to those customers, and our reputation may suffer. If significant numbers of our customers under contracts for use of our equipment and consumable supplies do not renew their contracts, our business will be adversely affected.

We have entered into agreements with independent third party distributors, including Henry Schein, which we anticipated to market and sell our products to a greater degree than in the recent past. Independent third-party distributors may be effective in increasing sales of our products to veterinarians, although we would expect a corresponding lower gross margin as such distributors typically buy products from us at a discount to end user prices. It is possible new or existing independent third-party distributors could cannibalize our direct sales efforts and lower our total gross margin. For us to be effective when working with an independent third-party distributor, the distributor must agree to market and/or sell our products and we must provide proper economic incentives to the distributor as well as contend effectively for the time, energy and focus of the employees of such distributor given other products the distributor may be carrying, potentially including those of our competitors. If we fail to be effective with new or existing independent third-party distributors, our financial performance may suffer.

Our stock price has historically experienced high volatility, and could do so in the future, including experiencing a material price decline resulting from a large sale in a short period of time.

Should a relatively large shareholder decide to sell a large number of shares in a short period of time, it could lead to an excess supply of our shares available for sale and correspondingly result in a significant decline in our stock price.

The securities markets have experienced significant price and volume fluctuations and the market prices of securities of many small cap companies have in the past been, and can in the future be expected to be, especially volatile. During the twelve months ended December 31, 2017, the closing stock price of our Public Common Stock has ranged from a low of $71.55 to a high of $110.24. Fluctuations in the trading price or liquidity of our Public Common Stock may adversely affect our ability to raise capital through future equity financings. Factors that may have a significant impact on the market price and marketability of our Public Common Stock include:


•	stock sales by large stockholders or by insiders;


•	changes in the outlook for our business;


•	our quarterly operating results, including as compared to expected revenue or earnings and in comparison to historical results;


•	termination, cancellation or expiration of our third-party supplier relationships;


•	announcements of technological innovations or new products by our competitors or by us;


•	litigation;


•	regulatory developments, including delays in product introductions;


•	developments or disputes concerning patents or proprietary rights;


•	availability of our revolving line of credit and compliance with debt covenants;


•	releases of reports by securities analysts;


•	economic and other external factors; and


•	general market conditions.

In the past, following periods of volatility in the market price of a company's securities, securities class action litigation has often been instituted. If a securities class action suit is filed against us, it is likely we would incur substantial legal fees and our management's attention and resources would be diverted from operating our business in order to respond to the litigation.

-20-

On May 4, 2010, our shareholders approved an amendment (the "Amendment") to our Restated Certificate of Incorporation. The Amendment places restrictions on the transfer of our stock that could adversely affect our ability to use our domestic Federal Net Operating Loss carryforward ("NOL"). In particular, the Amendment prevents the transfer of shares without the approval of our Board of Directors if, as a consequence, an individual, entity or groups of individuals or entities would become a 5-percent holder under Section 382 of the Internal Revenue Code of 1986, as amended, and the related Treasury regulations, and also prevents any existing 5-percent holder from increasing his or her ownership position in the Company without the approval of our Board of Directors. Any transfer of shares in violation of the Amendment (a "Transfer Violation") shall be void ab initio under the our Restated Certificate of Incorporation, as amended (our "Certificate of Incorporation") and our Board of Directors has procedures under our Certificate of Incorporation to remedy a Transfer Violation including requiring the shares causing such Transfer Violation to be sold and any profit resulting from such sale to be transferred to a charitable entity chosen by the Company's Board of Directors in specified circumstances. The Amendment could have an adverse impact on the value and trading liquidity of our stock if certain buyers who would otherwise have bid on or purchased our stock, including buyers who may not be comfortable owning stock with transfer restrictions, do not bid on or purchase our stock as a result of the Amendment. In addition, because some corporate takeovers occur through the acquirer's purchase, in the public market or otherwise, of sufficient shares to give it control of a company, any provision that restricts the transfer of shares can have the effect of preventing a takeover. The Amendment could discourage or otherwise prevent accumulations of substantial blocks of shares in which our stockholders might receive a substantial premium above market value and might tend to insulate management and the Board of Directors against the possibility of removal to a greater degree than had the Amendment not passed.

In February 2018, our Board of Directors granted a waiver to a non-affiliated stockholder to allow the purchase, subject to certain limitations, of up to 730,000 shares of our common stock without causing a Transfer Violation. This waiver can be withdrawn by our Board of Directors at any time, in which case the non-affiliated stockholder is to only sell our stock until the non-affiliated stockholder ceases to be a Five Percent Shareholder (as defined in our Certificate of Incorporation). This waiver, and any similar waivers that our Board of Directors may grant in the future, may make it more likely that we have a "change of ownership" as defined under the provisions of Section 382 of the Internal Revenue Code of 1986, as amended, which could place a significant restriction on our ability to utilize our domestic Federal NOL in the future and materially adversely affect our results of operations.

Our Credit Facility contains restrictions that may limit our flexibility in operating our business.

In July 2017, we entered into a Credit Agreement (the "Credit Agreement") with JPMorgan Chase Bank, N.A. ("Chase"), which provides for a revolving credit facility of up to $30.0 million (the "Credit Facility"). The Credit Facility contains various financial and non-financial operating covenants that limit our ability to engage in specified types of transactions. The financial covenants require that we maintain a minimum fixed charge coverage ratio and a maximum leverage ratio. The operating covenants limit our ability to, among other things:


•	sell, transfer, lease or dispose of our assets;


•	create, incur or assume additional indebtedness;


•	encumber or permit lines on certain of our assets;


•	make restricted payments, including paying dividends on, repurchasing or making distributions with respect to our common stock;


•	make specified investments (including loans and advances);


•	consolidate, merge, sell or otherwise dispose of all our substantially all of our assets; and


•	enter into certain transactions.

-21-

A breach of any of these covenants or a material adverse change to our business could result in a default under the Credit Agreement. Upon the occurrence of an event of default under our Credit Agreement, our lenders could elect to declare all amounts outstanding to be immediately due and payable and terminate all commitments to extend further credit. If we were unable to repay those amounts, the lenders could proceed against the collateral granted to them to secure such indebtedness.

Interpretation of existing legislation, regulations and rules, including financial accounting standards, or implementation of future legislation, regulations and rules could cause our costs to increase or could harm us in other ways.

We prepare our financial statements in conformance with United States generally accepted accounting principles, or US GAAP. These accounting principles are established by and are subject to interpretation by the SEC, the FASB and others who interpret and create accounting policies. A change in those policies or how those policies are interpreted can have a significant effect on our reported results and may affect our reporting of transactions completed before a change is made effective. Such changes may adversely affect our reported financial results and the way we conduct our business, or have a negative impact on us if we fail to track such changes.

If our regulators and/or auditors adopt or interpret more stringent standards than we anticipate, we could experience unanticipated changes in our reported financial statements, including but not limited to restatements, which could adversely affect our business due to litigation and investor confidence in our financial statements. In addition, changes in the underlying circumstances to which we apply given accounting standards and principles may affect our results of operations and have a negative impact on us. For example, we review goodwill recognized on our consolidated balance sheets at least annually and if we were to conclude there was an impairment of goodwill, we would reduce the corresponding goodwill to its estimated fair value and recognize a corresponding expense in our statement of operations. This impairment and corresponding expense could be as large as the total amount of goodwill recognized on our consolidated balance sheets, which was $26.7 million at December 31, 2017. There can be no assurance that future goodwill impairments will not occur if projected financial results are not met, or otherwise.

The Sarbanes-Oxley Act of 2002 ("Sarbanes-Oxley") has increased our required administrative actions and expenses as a public company since its enactment. The general and administrative costs of complying with Sarbanes-Oxley will depend on how it is interpreted over time. Of particular concern are the level of standards for internal control evaluation and reporting adopted under Section 404 of Sarbanes-Oxley. If our regulators and/or auditors adopt or interpret more stringent standards than we anticipate, we and/or our auditors may be unable to conclude that our internal controls over financial reporting are designed and operating effectively, which could adversely affect investor confidence in our financial statements and cause our stock price to decline. Even if we and our auditors are able to conclude that our internal control over financial reporting is designed and operating effectively in such a circumstance, our general and administrative costs are likely to increase. For example, in both 2017 and 2016, we were required to have our independent registered public accountant conduct an audit of our internal control over financial reporting because as of June 30 of both years our stock market value was above a certain level prescribed by regulation. This increased our general and administrative costs from what they otherwise would have been.

Similarly, we are required to comply with the SEC's mandate to provide interactive data using the eXtensible Business Reporting Language as an exhibit to certain SEC filings. Compliance with this mandate has required a significant time investment, which has and may in the future preclude some of our employees from spending time on more productive matters. In addition, future legislative, regulatory or rule-making action or more stringent interpretations of existing legislation, regulations and rules may increase our general and administrative costs or have other adverse effects on us.

-22-

Finally, changes in our tax environment could cause volatility or have an adverse effect on our business and financial results, as taxes are a significant component of our expenses. On December 22, 2017, H.R. 1, also known as the Tax Cuts and Jobs Act (the “Act”), was enacted into law. The resulting changes in US corporate tax rates, revised rules and taxing regimes could result in a material effect to our results of operations, deferred tax asset value, and financial condition. Additionally, at this point, it is unclear how many US states will incorporate these federal law changes into their local laws, and to what extent. We are continuing to evaluate the Act and the resulting impacts. If our complete and final assessment and understanding of the 2017 Tax Act differs significantly from this initial assessment, or the forthcoming rules, regulations and interpretations change our preliminary conclusions, the resulting impacts could have a material adverse impact on our tax rate and tax expense.

We intend to pursue acquisitions and other strategic development opportunities, which may not result as desired and could be detrimental to our financial position.

We intend to pursue acquisitions and other strategic development opportunities, including minority investments where strategic. The ultimate business and financial performance of these opportunities may not create, and may end up adversely affecting materially, the value we hope to enhance by pursuing them. Any acquisition may significantly underperform relative to our financial expectations and may serve to diminish rather than enhance shareholder value.

The success of any acquisition will depend on, among other things, our ability to integrate assets and personnel acquired in these transactions and to apply our internal controls process to these acquired businesses. The integration of acquisitions may require significant attention from our management, and the diversion of management's attention and resources could have a material adverse effect on our ability to manage our business. Furthermore, we may not realize the degree or timing of benefits we anticipated when we first entered into the acquisition transaction. If actual integration costs are higher than amounts originally anticipated, if we are unable to integrate the assets and personnel acquired in an acquisition as anticipated, or if we are unable to fully benefit from anticipated synergies, our business, financial condition, results of operations, and cash flows could be materially adversely affected. Furthermore, it is possible we will use management time and resources to pursue opportunities we ultimately are unable or decide not to consummate, in which case, we may not be able to utilize such management time and resources on what may have proved to be more productive matters in other areas of our business.

Obtaining and maintaining regulatory approvals in order to market our products may be costly and delay the marketing and sales of our products. Failure to meet all regulatory requirements could cause significant losses from affected inventory and the loss of market share.

Many of the products we develop, market or manufacture may subject us to extensive regulation by one or more of the USDA, the FDA, the EPA and foreign and other regulatory authorities. These regulations govern, among other things, the development, testing, manufacturing, labeling, storage, pre-market approval, advertising, promotion and sale of some of our products. Satisfaction of these requirements can take several years and time needed to satisfy them may vary substantially, based on the type, complexity and novelty of the product. The decision by a regulatory authority to regulate a currently non-regulated product or product area could significantly impact our revenue and have a corresponding adverse impact on our financial performance and position while we attempt to comply with the new regulation, if such compliance is possible at all.

The effect of government regulation may be to delay or to prevent marketing of our products for a considerable period of time and to impose costly procedures upon our activities. We may not be able to estimate the time to obtain required regulatory approvals accurately and such approvals may require

-23-

significantly more time than we anticipate. We have experienced in the past, and may experience in the future, difficulties that could delay or prevent us from obtaining the regulatory approval or license necessary to introduce or market our products. Such delays in approval may cause us to forego a significant portion of a new product's sales in its first year due to seasonality and advanced booking periods associated with certain products. Regulatory approval of our products may also impose limitations on the indicated or intended uses for which our products may be marketed.

Difficulties in making established products to all regulatory specifications may lead to significant losses related to affected inventory as well as market share. Among the conditions for certain regulatory approvals is the requirement that our facilities and/or the facilities of our third-party manufacturers conform to current Good Manufacturing Practices and other requirements. If any regulatory authority determines that our manufacturing facilities or those of our third-party manufacturers do not conform to appropriate manufacturing requirements, we or the manufacturers of our products may be subject to sanctions, including, but not limited to, warning letters, manufacturing suspensions, product recalls or seizures, injunctions, refusal to permit products to be imported into or exported out of the United States, refusals of regulatory authorities to grant approval or to allow us to enter into government supply contracts, withdrawals of previously approved marketing applications, civil fines and criminal prosecutions. Furthermore, third parties may perceive procedures required to obtain regulatory approval objectionable and may attempt to disrupt or otherwise damage our business as a result. In addition, certain of our agreements may require us to pay penalties if we are unable to supply products, including for failure to maintain regulatory approvals.

Any of these events, alone or in combination with others, could damage our business.

Our future revenues depend on successful product development, commercialization and/or market acceptance, any of which can be slower than we expect or may not occur.

The product development and regulatory approval process for many of our potential products is extensive and may take substantially longer than we anticipate. Research projects may fail. New products that we may be developing for the veterinary marketplace may not perform consistently within our expectations. Because we have limited resources to devote to product development and commercialization, any delay in the development of one product or reallocation of resources to product development efforts that prove unsuccessful may delay or jeopardize the development of other product candidates. If we fail to successfully develop new products and bring them to market in a timely manner, our ability to generate additional revenue will decrease.

Even if we are successful in the development of a product or obtain rights to a product from a third-party supplier, we may experience delays or shortfalls in commercialization and/or market acceptance of the product. For example, veterinarians may be slow to adopt a product, a product may not achieve the anticipated technical performance in field use or there may be delays in producing large volumes of a product. The former is particularly likely where there is no comparable product available or historical precedent for such a product. The ultimate adoption of a new product by veterinarians, the rate of such adoption and the extent veterinarians choose to integrate such a product into their practice are all important factors in the economic success of any new products and are factors that we do not control to a large extent. If our products do not achieve a significant level of market acceptance, demand for our products will not develop as expected and our revenues will be lower than we anticipate.

Many of our expenses are fixed and if factors beyond our control cause our revenue to fluctuate, this fluctuation could cause greater than expected losses, cash flow and liquidity shortfalls.

We believe that our future operating results will fluctuate on a quarterly basis due to a variety of factors which are generally beyond our control, including:

-24-


•	supply of products, including minimum purchase agreements, from third-party suppliers or termination, cancellation or expiration of such relationships;


•	competition and pricing pressures from competitive products;


•	the introduction of new products or services by our competitors or by us;


•	large customers failing to purchase at historical levels;


•	fundamental shifts in market demand;


•	manufacturing delays;


•	shipment problems;


•	information technology problems, which may prevent us from conducting our business effectively, or at all, and may also raise our costs;


•	regulatory and other delays in product development;


•	product recalls or other issues which may raise our costs;


•	changes in our reputation and/or market acceptance of our current or new products; and


•	changes in the mix of products sold.

We have high operating expenses, including those related to personnel. Many of these expenses are fixed in the short term and may increase over time. If any of the factors listed above cause our revenues to decline, our operating results could be substantially harmed.

Cyberattack related breaches of the Company’s information technology systems could have an adverse effect on our business.

Cyberattacks, ranging from the use of malware, computer viruses, dedicated denial of services attacks, credential harvesting, social engineering and other means for obtaining unauthorized access to or disrupting our Company’s ability to operate normally, could have an effect on our business. Cyberattacks may cause equipment failures, loss of information, including sensitive personal information of vendors, customers or employees or valuable technical and marketing information, as well as disruptions to our or our vendor or customers’ operations. These attacks may be committed by company employees or external actors operating in any geography, including jurisdictions where law enforcement measures to address such attacks are unavailable or ineffective. Cyberattacks may occur alone or in conjunction with physical attacks, especially where disruption of service is an objective of the attacker. While, to date, we have not been subject to cyberattacks which, individually or in the aggregate, have been material to Heska Corporation’s operations or financial condition, the preventive actions we take to reduce the risks associated with cyberattacks, including protection of our systems and networks, may be insufficient to repel or mitigate the effects of a major cyberattack in the future.

The Company devotes significant resources to network security, data encryption and other security measures to protect its systems and data, but these security measures cannot provide absolute security. The Company requires user names and passwords to access its information technology systems. The Company also uses encryption and authentication technologies designed to secure the transmission and storage of data and prevent unauthorized access. The Company also conducts periodic internal training and educational communications to raise and maintain employee cybersecurity awareness. To the extent the Company was to experience a breach of its systems and was unable to protect sensitive data, such a breach could materially damage business partner and customer relationships, and reduce or otherwise negatively impact access to online services. Moreover, if a computer security breach affects the Company’s systems or results in the unauthorized release of Personally Identifiable Information (PII), the Company’s reputation and brand could be materially damaged. Use of the Company’s products and services could decrease, and the Company could be exposed to a risk of loss or litigation and possible liability.

-25-

We have less than 300 holders of record, which could allow us to terminate voluntarily the registration of our common stock with the SEC and after which we would no longer be eligible to maintain the listing of our Public Common Stock on the Nasdaq Capital Market. We may also be unable to otherwise maintain our listing on the Nasdaq Capital Market.

We have less than 300 holders of record as of our latest information, a fact which could make us eligible to terminate voluntarily the registration of our common stock with the SEC and therefore suspend our reporting obligations with the SEC under the Exchange Act and become a non-reporting company. If we were to cease reporting with the SEC, we would no longer be eligible to maintain the listing of our common stock on the Nasdaq Capital Market, which we would expect to materially adversely affect the liquidity and market price for our common stock. The Nasdaq Capital Market has several additional quantitative and qualitative requirements companies must comply with to maintain this listing. While we believe, we are currently in compliance with all Nasdaq requirements, there can be no assurance we will continue to meet Nasdaq listing requirements, that Nasdaq will interpret these requirements in the same manner we do if we believe we meet the requirements, or that Nasdaq will not change such requirements or add new requirements to include requirements we do not meet in the future.

If we are delisted from the Nasdaq Capital Market, our Public Common Stock may be considered a penny stock under the regulations of the SEC and would therefore be subject to rules that impose additional sales practice requirements on broker-dealers who sell our securities. The additional burdens imposed upon broker-dealers may discourage broker-dealers from effecting transactions in our Public Common Stock, which could severely limit market liquidity of the Public Common Stock and any stockholder's ability to sell our securities in the secondary market. This lack of liquidity would also likely make it more difficult for us to raise capital in the future.

We may not be able to continue to achieve sustained profitability or increase profitability on a quarterly or annual basis.

Prior to 2005, we incurred net losses on an annual basis since our inception in 1988 and, as of December 31, 2017, we had an accumulated deficit of $143.5 million. Relatively small differences in our performance metrics may cause us to generate an operating or net loss in future periods. Our ability to continue to be profitable in future periods will depend, in part, on our ability to increase sales in our CCA segment, including maintaining and growing our installed base of instruments and related consumables, to maintain or increase gross margins and to limit the increase in our operating expenses to a reasonable level as well as avoid or effectively manage any unanticipated issues. We may not be able to generate, sustain or increase profitability on a quarterly or annual basis. If we cannot achieve or sustain profitability for an extended period, we may not be able to fund our expected cash needs, including the repayment of debt as it comes due, or continue our operations.

We may face product returns and product liability litigation in excess of, or not covered by, our insurance coverage or indemnities and/or warranties from our suppliers. If we become subject to product liability claims resulting from defects in our products, we may fail to achieve market acceptance of our products and our sales could substantially decline.

The testing, manufacturing and marketing of our current products as well as those currently under development entail an inherent risk of product liability claims and associated adverse publicity. Following the introduction of a product, adverse side effects may be discovered. Adverse publicity regarding such effects could affect sales of our other products for an indeterminate time period. To date, we have not experienced any material product liability claims, but any claim arising in the future could substantially harm our business. Potential product liability claims may exceed the amount of our insurance coverage or may be excluded from

-26-

coverage under the terms of the policy. We may not be able to continue to obtain adequate insurance at a reasonable cost, if at all. In the event that we are held liable for a claim against which we are not indemnified or for damages exceeding the $10 million limit of our insurance coverage or which results in significant adverse publicity against us, we may lose revenue, be required to make substantial payments which could exceed our financial capacity and/or lose or fail to achieve market acceptance.

We may be held liable for the release of hazardous materials, which could result in extensive remediation costs or otherwise harm our business.

Certain of our products and development programs produced at our Des Moines, Iowa facility involve the controlled use of hazardous and bio hazardous materials, including chemicals and infectious disease agents. Although we believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by applicable local, state and federal regulations, we cannot eliminate the risk of accidental contamination or injury from these materials. In the event of such an accident, we could be held liable for any fines, penalties, remediation costs or other damages that result. Our liability for the release of hazardous materials could exceed our resources, which could lead to a shutdown of our operations, significant remediation costs and potential legal liability. In addition, we may incur substantial costs to comply with environmental regulations if we choose to expand our manufacturing capacity.


Item 1B.	Unresolved Staff Comments

None.


Item 2.	Properties

Our principal administrative and research and development activities are located in Loveland, Colorado. We lease approximately 60,000 square feet at a facility in Loveland, Colorado under an agreement which expires in 2023. Our principal production facility located in Des Moines, Iowa, consists of 168,000 square feet of buildings on 34 acres of land, which we own. We also own a 175-acre farm used principally for testing products, located in Carlisle, Iowa. Our European facility in Fribourg, Switzerland has approximately 6,000 square feet leased under an agreement which expires in 2022.


Item 3.	Legal Proceedings

From time to time, we may be involved in litigation related to claims arising out of our operations. On March 12, 2015, a complaint was filed against us by Shaun Fauley in the United States District Court Northern District of Illinois alleging our transmittal of unauthorized faxes in violation of the federal Telephone Consumer Protection Act of 1991, as amended by the Junk Fax Prevention Act of 2005, as a class action seeking stated damages of the greater of actual monetary loss or five hundred dollars per violation. The Company intends to defend itself vigorously in this matter and at this time is unable to estimate a possible loss or range of loss. As of December 31, 2017, we were not a party to any other legal proceedings that are expected, individually or in the aggregate, to have a material adverse effect on our business, financial condition or operating results.

Item 7.	Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with "Selected Financial Data" and the Consolidated Financial Statements and related Notes included in Items 6 and 8, respectively, of this Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. Such statements, which include statements concerning future revenue sources and concentration, gross profit margins, selling and marketing expenses, research and development expenses, general and administrative expenses, capital resources, additional financings or borrowings and additional losses, are subject to risks and uncertainties, including, but not limited to, those discussed below and elsewhere in this Form 10-K, particularly in Item 1A "Risk Factors," that could cause actual results to differ materially from those projected. The forward-looking statements set forth in this Form 10-K are as of the close of business on March 8, 2018, and we undertake no duty and do not intend to update this information, except as required by applicable securities laws.

Overview

We sell advanced veterinary diagnostic and specialty products. Our offerings include point of care diagnostics laboratory instruments and supplies, digital imaging diagnostics products, vaccines, local and cloud-based data services, allergy testing and immunotherapy, and single-use offerings such as in-clinic diagnostic tests and heartworm preventive products. Our core focus is on supporting veterinarians in the canine and feline healthcare space.

Our business is composed of two reportable segments, Core Companion Animal Health ("CCA") and Other Vaccines, Pharmaceuticals and Products ("OVP"). The CCA segment includes, primarily for canine and feline use, point of care laboratory instruments and supplies, digital imaging products, software and services, local and cloud-based data services, allergy testing and immunotherapy, and single use offerings such as in-clinic diagnostic tests and heartworm preventive products. The OVP segment includes private label vaccine and pharmaceutical production, primarily for cattle but also for other species including equine, porcine, avian, feline and canine.

Core Companion Animal Health ("CCA"), represented 81% of our 2017 revenue. Other Vaccines, Pharmaceuticals and Products ("OVP"), represented 19% of our 2017 revenue. OVP products are sold by third parties under third party labels.

The CCA segment includes, primarily for canine and feline use, point of care diagnostics consisting of laboratory instruments and supplies, digital imaging products, software and services, local and cloud-based data services, allergy testing and immunotherapy, and single use offerings such as in-clinic diagnostic tests and heartworm preventive products.

Revenue from point of care laboratory includes instruments, consumables, and other revenue such as service represented $54.9 million, $48.8 million, and $38.6 million, of our 2017, 2016, and 2015 revenue, respectively. Revenue in this area primarily involves placing an instrument under contract in the field and generating future revenue from testing consumables, such as cartridges and reagents, as that instrument is used. Approximately $39.2 million, $36.3 million, and $30.6 million of our 2017, 2016, and 2015 revenue, respectively, resulted from the sale of such testing consumables to an installed base of instruments. Approximately $13.8 million, $10.4 million, and $5.9 million, of our 2017, 2016 and 2015 revenue, respectively, was from instrument sales. Approximately $1.9 million, $2.0 million, and $2.2 million, of our 2017, 2016 and 2015 revenue, respectively, was from other revenue sources, such as charges for repairs. Instruments placed under subscription agreements are considered operating or sales-type (capital) leases, depending on the duration and other factors of the underlying agreement. A loss of, or disruption in, the

-31-

supply of consumables we are selling to an installed base of instruments could substantially harm our business. All of our point of care laboratory and other non-imaging instruments and supplies are supplied by third parties, who typically own the product rights and supply the product to us under marketing and/or distribution agreements. In many cases, we have collaborated with a third party to adapt a human instrument for veterinary use. Major products in this area include our instruments for chemistry, hematology, blood gas, and immunodiagnostic testing and their affiliated operating consumables.

Imaging hardware, software and services represented approximately $21.9 million, $29.6 million, and $19.6 million of 2017, 2016, and 2015 revenue, respectively. Digital radiography is the largest product offering in this area, which also includes ultrasound instruments. Digital radiography solutions typically consist of a combination of hardware and software placed with a customer, often combined with an ongoing service and support contract. We sell our imaging solutions both in the United States and internationally. Our experience has been that most of the revenue is generated at the time of sale in this area, in contrast to the point of care diagnostics laboratory placements discussed above where ongoing consumable revenue is often a larger component of economic value as a given instrument is used.

Other CCA revenue, including single use diagnostic and other tests, pharmaceuticals and biologicals as well as research and development, licensing and royalty revenue, represented $25.6 million, $26.3 million, and $23.5 million of our 2017, 2016, and 2015 revenue, respectively. Since items in this area are often single use by their nature, our typical aim is to build customer satisfaction and loyalty for each product, generate repeat annual sales from existing customers and expand our customer base in the future. Products in this area are both supplied by third parties and provided by us. Major products and services in this area include heartworm diagnostic tests and preventives, and allergy test kits, allergy immunotherapy and testing.

We consider the CCA segment to be our core business and devote most of our management time and other resources to improving the prospects for this segment. Maintaining a continuing, reliable and economic supply of products we currently obtain from third parties is critical to our success in this area. Virtually all of our sales and marketing expenses occur in the CCA segment. The majority of our research and development spending is dedicated to this segment as well.

All of our CCA products are ultimately sold primarily to or through veterinarians. In many cases, veterinarians will mark up their costs to their customer. The acceptance of our products by veterinarians is critical to our success. CCA products are sold directly to end users by us as well as through distribution relationships, such as our agreement with Intervet Inc., d/b/a Merck Animal Health ("Merck Animal Health"), the sale of kits to conduct blood testing to third-party veterinary diagnostic laboratories and independent third-party distributors. Revenue from direct sales and distribution relationships represented approximately 58% and 42%, respectively, of CCA 2017 revenue, 61% and 39%, respectively, of CCA 2016 revenue, and 66% and 34%, respectively, of CCA 2015 revenue.

The OVP segment includes our 168,000 square foot USDA and FDA licensed production facility in Des Moines, Iowa. We view this facility as an asset which could allow us to control our cost of goods on any pharmaceuticals and vaccines that we may commercialize in the future. We have increased integration of this facility with our operations elsewhere. For example, virtually all our US inventory, excluding our imaging products, is now stored at this facility and related fulfillment logistics are managed there. CCA segment products manufactured at this facility are transferred at cost and are not recorded as revenue for our OVP segment. We view OVP reported revenue as revenue primarily to cover the overhead costs of the facility and to generate incremental cash flow to fund our CCA segment.

Historically, a significant portion of our OVP segment's revenue has been generated from the sale of certain bovine vaccines, which have been sold primarily under the Titanium® and MasterGuard® brands. We have an agreement with Eli Lilly and Company ("Eli Lilly") and its affiliates operating through Elanco for the

-32-

production of these vaccines. Our OVP segment also produces vaccines and pharmaceuticals for other third parties.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations is based upon the consolidated financial statements, which have been prepared in accordance with US generally accepted accounting principles ("GAAP"). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Significant estimates are required when establishing the allowance for doubtful accounts and the provision for excess or obsolete inventory, in determining future costs associated with warranties provided, in determining the period over which our obligations are fulfilled under agreements to license product rights and/or technology rights, estimating the useful lives of equipment under leasing arrangements, estimating the expense associated with the granting of stock, and in determining the need for, and the amount of, a valuation allowance on deferred tax assets. We consider the following to be our critical accounting estimates.

Revenue Recognition

We generate our revenue through the sale of products, either by outright purchase by our customers or through a subscription agreement whereby our customers receive equipment and pay us a monthly fee for the usage of the equipment as well as, when applicable, the consumables needed to conduct testing. Outright sales to customers is the majority of imaging diagnostics transactions, while subscription placement is the majority of point of care diagnostics laboratory transactions. We also may recognize revenue through licensing of technology product rights, royalties and sponsored research and development. Our policy is to recognize revenue when the applicable revenue recognition criteria have been met, which generally include the following:


•	Persuasive evidence of an arrangement exists;


•	Delivery has occurred or services rendered;


•	Price is fixed or determinable; and


•	Collectability is reasonably assured.

Revenue from the outright sale of products to customers is recognized after both the goods are shipped to the customer and acceptance has been received, if required, with an appropriate provision for estimated returns and allowances. We do not permit general returns of products sold.

Revenue from our point of care diagnostics laboratory subscription agreements is recognized based on the length of the agreements that are signed by our customers. Among other factors, the length of the agreement determines whether a subscription is considered an operating lease or capital lease. Our capital leases qualify for sales-type lease treatment. For subscription agreements that are considered operating leases, we recognize revenue of our subscriptions ratably over the term of the agreement. The equipment is transferred from inventory to property, plant and equipment and depreciated into cost of goods sold over the term of the agreement, based on the assets’ useful life, typically over a five to seven-year period depending on the circumstance under which the instrument is placed with the customer. Revenue from subscription agreements that are sales-type (capital) leases is recognized, along with the associated cost of the equipment, at the time of placement in our customer’s location. The amount of revenue recognized at the time of lease

-33-

inception is based on, along with other factors, observable prior sales prices of similar equipment sold by us over the prior twelve months, relative to total contract value. We record a short and long-term capital lease receivable related to sales-type leases.

Revenue from our rentals of digital imaging equipment is recognized ratably over the term of the rental agreement, which is typically over a 26-month period. The equipment is transferred from inventory to property, plant and equipment and depreciated over the assets' useful life. At the conclusion of these arrangements, customers generally have the option to (a) extend the rental agreement for an additional term, (b) purchase the items for a price negotiated at the inception of the rental, less rental payments paid or (c) pay a termination and recovery fee and return the items and terminate the agreement.

Recording revenue from the sale of products involves the use of estimates and management's judgment. We must make a determination at the time of sale whether the customer has the ability to make payments in accordance with arrangements. While we do utilize past payment history and, to the extent available for new customers, public credit information in making our assessment, the determination of whether collectability is reasonably assured is ultimately a judgment that must be made by management. We must also make estimates regarding our future obligations relating to returns, rebates, allowances and similar other programs.

License revenue under arrangements to sell or license product rights or technology rights is recognized as obligations under the agreement are satisfied, which generally occurs over a period of time. Generally, licensing revenue is deferred and recognized over the estimated life of the related agreements, products, patents or technology. Nonrefundable licensing fees, marketing rights and milestone payments received under contractual arrangements are deferred and recognized over the remaining contractual term using the straight-line method.

Recording revenue from license arrangements involves the use of estimates. The primary estimate made by management is determining the useful life of the related agreement, product, patent or technology. We evaluate all of our licensing arrangements by estimating the useful life of either the product or the technology, the length of the agreement or the legal patent life and defer the revenue for recognition over the appropriate period.

We enter into arrangements that include multiple elements. In these situations, we must determine whether the various elements meet the criteria to be accounted for as separate elements. If the elements cannot be separated, revenue is recognized once revenue recognition criteria for the entire arrangement have been met or over the period that the Company's obligations to the customer are fulfilled, as appropriate. If the elements are determined to be separable, the revenue is allocated to the separate elements based on relative fair value and recognized separately for each element when the applicable revenue recognition criteria have been met. In accounting for these multiple element arrangements, we must make determinations about whether elements can be accounted for separately and make estimates regarding their relative fair values.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers” and has subsequently issued several supplemental and/or clarifying ASUs (collectively “ASC 606”). ASC 606 prescribes a single common revenue standard that replaces most existing US GAAP revenue recognition guidance. ASC 606 outlines a five-step model, under which Heska will recognize revenue as performance obligations within a customer contract are satisfied. ASC 606 is intended to provide more consistent interpretation and application of the principles outlined in the standard across filers in multiple industries and within the same industries compared to current practices, which should improve comparability. Along with the issuance of ASC 606, additional cost guidance was issued and codified under ASC 340-40 that outlines the requirement for capitalizing incremental costs of obtaining a contract and costs to fulfill a contract that meet certain capitalization criteria.

-34-

Adoption of ASC 606 is required for annual reporting periods beginning after December 15, 2017, including interim periods within the reporting period. Upon adoption, Heska must elect to adopt either retrospectively to each prior reporting period presented (full retrospective method) or using the cumulative effect transition method with the cumulative effect of initial adoption recognized at the date of initial application (modified retrospective method). Heska has elected to adopt the modified retrospective method and apply this method to contracts not yet completed as of January 1, 2018. The cumulative effect of initially applying the new revenue standard is recognized as an adjustment to the opening balance of our fiscal year 2018 retained earnings. The comparative information will not be recast and will continue to be reported under the accounting standards in effect for those periods.

Heska assessed the impact that the future adoption of ASC 606 is expected to have on its Consolidated Financial Statements by analyzing its current portfolio of customer contracts and various revenue streams, including a review of historical accounting policies and practices to identify potential differences in applying the guidance of ASC 606. Heska also performed a comprehensive review of its current processes and systems to determine and implement changes required to support the adoption of ASC 606 on January 1, 2018.

Based on review of customer contracts within our Core Companion Animal segment, Heska has determined the timing of revenue recognition of our product sales, which includes upfront equipment sales and sales of consumables, will continue to be recognized as it is currently, generally upon shipment of products. Also included within CCA are our subscription agreements, which contain a lease of equipment, for which rental income will continue to be recognized under ASC 840, Leases, unless the equipment is considered a sales-type lease and revenue will be recognized under ASC 606 at the point of sale. Often our contracts contain multiple performance obligations to which the transaction price must be allocated. The objective when allocating the transaction price is to allocate the transaction price to each performance obligation (or distinct good or service) in an amount that depicts the consideration to which the entity expects to be entitled in exchange for transferring the promised goods or services to the customer. All of the individual performance obligations, including equipment, consumables and services are sold separately, and therefore, observable prices are available.

Based on review of customer contracts within our Other Vaccines, Pharmaceuticals, and Products segment, Heska has determined that the timing of revenue recognition of our customer contracts will continue to be recognized as it is currently - generally upon shipment or acceptance by our customer. Heska assessed the over-time criteria within ASC 606 and concluded that because products within this segment have no alternative use to Heska as Heska is contractually prohibited to redirect the product to other customers, Heska does not have right to payment for performance to date and therefore, point in time recognition is appropriate.

In addition, ASC 606 states that "an asset recognized in accordance with the incremental costs of obtaining a contract shall be amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates". Because a significant number of Heska’s customers are under noncancelable contracts for periods extending beyond one year with the delivery of goods and services occurring throughout the duration, Heska anticipates recording an asset related to the prepayment of such contract acquisition costs.

We expect the impact of the adoption of the new standard will result in an adjustment to the following recognition of software support revenue, which historically has been a separate element however this has been deemed to be an immaterial promise and therefore, previously deferred revenue relating to software support will be recognized at point of sale along with the equipment and embedded software. The adoption of the new standard will also impact the recognition of sales commissions. Previously, sales commissions were expensed

-35-

when the underlying contract was executed, which will now be recognized as a cost to acquire a contract and amortized over its useful life. Finally, the new standard will impact the recognition of revenue associated with certain bill and hold arrangements. Previously, we deferred revenue recognition until shipment, which will now be recognized upon customer acceptance. We are finalizing the quantitative impact of these changes.

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts receivable based on client-specific allowances, as well as a general allowance. Specific allowances are maintained for clients which are determined to have a high degree of collectability risk based on such factors, among others, as: (i) the aging of the accounts receivable balance; (ii) the client's past payment history; and (iii) a deterioration in the client's financial condition, evidenced by weak financial condition and/or continued poor operating results, reduced credit ratings, and/or a bankruptcy filing. In addition to the specific allowance, the Company maintains a general allowance for credit risk in its accounts receivable which is not covered by a specific allowance. The general allowance is established based on such factors, among others, as: (i) the total balance of the outstanding accounts receivable, including considerations of the aging categories of those accounts receivable; (ii) past history of uncollectable accounts receivable write-offs; and (iii) the overall creditworthiness of the client base. A considerable amount of judgment is required in assessing the realizability of accounts receivable. Should any of the factors considered in determining the adequacy of the overall allowance change, an adjustment to the provision for doubtful accounts receivable may be necessary.

Inventories

Inventories are stated at the lower of cost or net realizable value, cost being determined on the first-in, first-out method. Inventories are written down if the estimated net realizable value of an inventory item is less than its recorded value. We review the carrying cost of our inventories by product each quarter to determine the adequacy of our reserves for excess and/or obsolete inventory. In accounting for inventories we must make estimates regarding the estimated net realizable value of our inventory. This estimate is based, in part, on our forecasts of future sales and shelf life of products.

Deferred Tax Assets – Valuation Allowance

We evaluate our ability to realize the tax benefits associated with a deferred tax asset (“DTA”) by analyzing our forecasted taxable income using both historical and projected future operating results, the reversal of existing temporary differences, taxable income in prior carry back years (if permitted) and the availability of tax planning strategies. A valuation allowance is required to be established unless management determines that it is more likely than not that we will ultimately realize the tax benefit associated with a deferred tax asset. As of December 31, 2016, a portion of our deferred tax assets, specifically our domestic federal and state net operating loss carryforwards ("NOL"), were reduced by a valuation allowance. As of December 31, 2017, due to the significant amount of additional stock-based compensation excess tax deductions generated, the Company determined that sufficient taxable income may not be generated to realize all of the DTAs as of December 31, 2017. As such, an additional valuation allowance of $2.9 million was recorded for the year against certain of the Company’s deferred tax assets. See Note 3 - Income Taxes in the accompanying notes to the consolidated financial statements for additional information regarding our income taxes.

Revenue

Total revenue decreased 1% to $129.3 million in 2017 compared to $130.1 million in 2016. Total revenue increased 24% to $130.1 million in 2016 compared to $104.6 million in 2015.

CCA segment revenue decreased 2% to $105.2 million in 2017 compared to $107.4 million in 2016. The decrease was driven primarily by a 26% decrease in revenue from sales of our imaging products, partially offset by a 12% increase in revenue from core point of care laboratory subscriptions, equipment and consumables. CCA segment revenue increased 27% to $107.4 million in 2016 compared to $84.2 million in 2015. The increase was driven primarily by greater sales of our digital imaging products, increased sales of our heartworm preventive products and increased installed base and revenue recognition of our instruments and sales of their associated consumables. These increases were partially offset by declines in sales of our heartworm diagnostic tests and allergy testing and treatments.

OVP segment revenue increased 6% to $24.2 million in 2017 compared to $22.7 million in 2016 and increased 11% to $22.7 million in 2016 compared to $20.3 million in 2015. The increase in 2017 from 2016 was due to various customer contracts. The increase in 2016 from 2015 was driven primarily by greater revenue from our contract with Elanco.

Gross Profit

Gross profit increased 8% to $58.3 million in 2017 compared to $53.9 million in 2016. Gross margin percent, which we derive by dividing gross profit by total revenue, increased to 45.0% in 2017 compared to 41.4% in 2016. The increase in gross profit was driven primarily by favorable pricing, while the increase in gross margin percentage was driven in part by favorable margins on consumables in our CCA segment and product mix in our OVP segment. Gross profit increased 22% to $53.9 million in 2016 compared to $44.2 million in 2015. Gross margin percent decreased to 41.4% in 2016 compared to 42.3% in 2015. This lower gross margin percentage was driven primarily by unfavorable product mix in our OVP segment as well as incremental sales from International Imaging, which contributes slightly lower gross margins than our domestic imaging products.

Operating Expenses

Selling and marketing expenses increased 5% to $23.2 million in 2017 compared to $22.1 million in 2016. The increase was driven primarily by a $1.0 million increase in compensation and benefits and a $0.3 million increase in stock compensation, partially offset by a $0.6 million decrease in commissions and other incentive compensation. Selling and marketing expenses increased 4% to $22.1 million in 2016 compared to $21.3 million in 2015. The increase was driven primarily by commissions paid on higher sales levels, particularly on our digital radiography sales and instrument placements.

-38-

Research and development expenses decreased 7% to $2.0 million in 2017, compared to $2.1 million in 2016, primarily driven by a decrease in other incentive compensation. Research and development increased 29% to $2.1 million in 2016, as compared to $1.7 million in 2015. The increase was driven primarily by spending on product development for digital radiography solutions.

General and administrative expenses increased 13% to $14.8 million in 2017, compared to $13.1 million in 2016. The increase was driven primarily by a $0.7 million increase in general consulting services, $0.6 million increase in compensation and benefits (net of a decrease in other incentive compensation), and a $0.2 million increase in severance expense. General and administrative expenses increased 4% to $13.1 million in 2016, as compared to $12.7 million in 2015. The increase was driven primarily by intangible amortization expense related to our acquisition of International Imaging.

Interest and Other Expense (Income), Net

Interest and other expense (income), net, was income of $150 thousand in 2017, as compared to an expense of $29 thousand in 2016 and expense of $130 thousand in 2015.

The increase in other income in 2017 was primarily driven by a $293 thousand increase in net foreign currency gains offset by a $85 thousand increase in interest expense. The decrease in other expense in 2016 as compared to 2015 was driven primarily by income received from the sale of an equity investment during the first quarter of 2016. This income was offset by minimum interest payments made on our line of credit and greater foreign currency losses.

Income Tax Expense

In 2017, we had total income tax expense of $8.91 million, including approximately $5.9 million related to the re-measurement of our deferred tax balances as a result of the US Tax Cuts and Jobs Act. In 2016 and 2015 respectively, we had total income tax expense of $4.3 million and $2.9 million. In 2017, our deferred income tax expense was increased by $5.9 million (i.e. the write down of deferred tax asset balances and the valuation allowance) for tax reform legislation and our current income tax expense was reduced by $5.5 million for employee share-based payment awards which are now recorded in the income statement in accordance with our accounting policy election. See Note 3 - Income Taxes in the accompanying notes to the consolidated financial statements for additional information regarding our income taxes.

On December 22, 2017, the tax legislation commonly known as The US Tax Cuts and Jobs Act was signed into law (the “Act”). This enactment resulted in a number of significant changes to US federal income tax law for US corporations. Most notably, the statutory US federal corporate income tax rate was reduced to 21%. In addition to the change in the corporate income tax rate, the Act further introduced a number of other changes including a one-time transition tax via a mandatory deemed repatriation of post-1986 undistributed foreign earnings and profits; the introduction of a tax on global intangible low-taxed income (“GILTI”) for tax years beginning after December 31, 2017; the further limitation of the deductibility of share-based compensation of certain highly compensated employees; and the repeal of the corporate alternative minimum tax; amongst other provisions. We are required to recognize the effect of the tax law changes in the period of enactment. Shortly after enactment, the Security and Exchange Commission (SEC) issued SAB 118, which provides guidance on accounting for the new legislation. Under SAB 118, an entity should recognize amounts for which accounting can be completed. Where accounting under ASC 740 is incomplete relative to certain income tax effects of tax reform, the entity should recognize provisional amounts and adjust such amounts as more information becomes available and disclose this information in its financial statements. The measurement period under SAB 118 is one year from date of enactment (with the approach being similar to business combinations). Due to the timing of enactment of the Act, and the ongoing guidance and accounting interpretation expected over the next 12 months, we consider the accounting for the transition tax, impact of

-39-

GILTI, deferred tax re-measurements, and other impacts of the Act applicable to the Company to be incomplete as of the balance sheet date. We expect to complete our analysis within the measurement period in accordance with SAB 118.

Net income attributable to Heska Corporation was $10.0 million in 2017, as compared to a net income attributable to Heska Corporation of $10.5 million in 2016 and net income attributable to Heska Corporation of $5.2 million in 2015. The difference between this line item and "Net Income" is the net income or loss attributable to our minority interest in US Imaging, prior to when we purchased it on May 31, 2017. The difference between these line items was a gain of $0.5 million in 2017, a loss of $1.7 million in 2016 and a loss of $0.3 million in 2015.

Non-GAAP Financial Measures

As discussed above, under Income Taxes, the caption, our deferred income tax expense was increased by $5.9 million due to the revaluation of our deferred tax assets as a result of the Act. On a non-GAAP basis, excluding the one-time tax adjustment, net income attributable to Heska was $15.9 million in 2017, as compared to $10.5 million in 2016. The following table is a reconciliation of the impact of this adjustment to the nearest U.S. GAAP financial measure:



	Year Ended December 31,
	2017		2016
U.S. GAAP: Net (loss) income attributable to Heska	$	9,953	$	10,508
Add: U.S. Tax Reform	5,898		—
Non-GAAP: Net income attributable to Heska excluding U.S. Tax Reform	$	15,851	$	10,508

U.S. GAAP: Diluted (loss) earnings per share attributable to Heska	$	1.30	$	1.43
Non-GAAP: Diluted earnings per share attributable to Heska	$	2.07	$	1.43

Weighted average outstanding shares used to compute diluted earnings per share attributable to Heska Corporation	7,642		7,361

Impact of Inflation

In recent years, inflation has not had a significant impact on our operations.

Liquidity, Capital Resources and Financial Condition

We believe that adequate liquidity and cash generation is important to the execution of our strategic initiatives. Our ability to fund our operations, acquisitions, capital expenditures, and product development efforts may depend on our ability to generate cash from operating activities which is subject to future operating performance, as well as general economic, financial, competitive, legislative, regulatory, and other conditions, some of which are beyond our control. Our primary sources of liquidity are our available cash, cash generated from current operations and availability under our credit facilities noted below.

For the year ended December 31, 2017, we had net income of $9.5 million and net cash provided by operations of $10.4 million. At December 31, 2017, we had $9.7 million of cash and cash equivalents, working capital of $37.2 million and $6.0 million outstanding borrowings under our revolving line of credit, discussed below.

-40-

On July 27, 2017, we entered into a Credit Agreement (the "Credit Agreement") with JPMorgan Chase Bank, N.A. ("Chase"), which provides for a revolving credit facility of up to $30.0 million (the "Credit Facility"). The Credit Facility provides us with the ability to borrow up to $30.0 million, although the amount of the Credit Facility may be increased by an additional $20.0 million up to a total of $50.0 million subject to receipt of additional lender commitments and other conditions. Any interest on borrowings due is to be charged at either the (i) rate of interest per annum publicly announced from time to time by Chase at its prime rate in effect at its principal offices in New York City, subject to a floor, minus 1.65%, or (ii) the interest rate per annum equal to (a) LIBOR for the interest period in effect multiplied by (b) Chase's Statutory Reserve Rate (as defined in the Credit Agreement), plus 1.10% and payable monthly. There is an annual minimum interest charge of $60 thousand under the Credit Agreement. Borrowings under the Credit Facility are subject to certain financial and non-financial covenants and are available for various corporate purposes, including general working capital, capital investments, and certain permitted acquisitions. Failure to comply with any of the covenants, representations or warranties could result in our being in default on the loan and could cause all outstanding amounts payable to Chase to become immediately due and payable or impact our ability to borrow under the agreement. The Credit Agreement also permits us to issue letters of credit. The maturity date of the Credit Facility is July 27, 2020. The foregoing discussion of the Credit Facility is a summary only and is qualified in its entirety by reference to the full text of the Credit Agreement, a copy of which has been filed as an exhibit to the Company's Current Report on Form 8-K filed with the SEC on August 2, 2017. At December 31, 2017, we had $6.0 million of borrowings outstanding on this line of credit and we were in compliance with all financial covenants.

A summary of our cash provided by and used in operating, investing and financing activities is as follows (in thousands):



	Years Ended December 31,
	2017			2016			2015
Net cash provided by operating activities	$	10,409		$	5,855		$	2,125
Net cash used in investing activities	(17,169		)	(3,302		)	(3,773		)
Net cash provided by financing activities	5,551			1,403			2,726
Effect of currency translation on cash	74			(52		)	(43		)
Increase (decrease) in cash and cash equivalents	(1,135		)	3,904			1,035
Cash and cash equivalents, beginning of the period	10,794			6,890			5,855
Cash and cash equivalents, end of the period	$	9,659		$	10,794		$	6,890

Net cash provided by operating activities was $10.4 million in 2017 as compared to net cash provided by operating activities of $5.9 million in 2016, an increase of approximately $4.6 million. The change was driven primarily by a $9.9 million increase in cash provided by accounts receivable, a $4.9 million increase in deferred tax expense, a $3.8 million increase in cash provided by accounts payable, a $1.0 million decrease in cash used for other non-current assets, a $0.9 million decrease in cash used by deferred revenue, and a $0.5 million increase in stock-based compensation. These factors were partially offset by a $9.1 million increase in cash used for inventory, a $2.7 million decrease in net income, a $1.4 million increase in cash used for other current assets, a $1.1 million decrease in cash provided by related party payables, a $0.9 million increase in cash used for accrued liabilities, and a $1.4 million increase in current and non-current lease receivables. Net cash provided by operating activities was $5.9 million in 2016 as compared to net cash provided by operating

-41-

activities of $2.1 million in 2015, an increase of approximately $3.7 million. The change was driven primarily by a $6.6 million increase in net income, a $2.6 million increase in the use of our deferred tax asset, a $2.5 million decrease in cash used for inventory, some of which related to inventory transferred to property, plant and equipment as rental units, a $1.9 million increase in cash provided by other current assets, a $1.4 million increase in cash provided by related party payables, and a $0.5 million increase in depreciation and amortization. These factors were partially offset a $3.7 million increase in cash used for accounts payable, a $2.9 million increase in cash used for non-current lease receivables, a $2.1 million increase in cash used by deferred revenue, a $0.9 million decrease in cash provided by related party receivables, and a $0.6 million increase in cash used for current lease receivables.

Net cash used in investing activities was $17.2 million in 2017 as compared to net cash used in investing activities of $3.3 million in 2016, an increase of approximately $13.9 million. The increase was driven primarily by our purchase of the minority interest in US Imaging for $13.8 million. Net cash used in investing activities was $3.3 million in 2016 as compared to net cash used in investing activities of $3.8 million in 2015, a decrease of approximately $0.5 million. The change was driven primarily by a $0.4 million decrease in purchases of property and equipment and $0.1 million of proceeds from the sale of an equity investment.

Net cash provided by financing activities was $5.6 million in 2017 as compared to net cash provided by financing activities of $1.4 million in 2016, an increase of approximately $4.1 million. The change was driven primarily by a $4.8 million increase in borrowings, net of repayments, partially offset by $1.0 million of distributions to non-controlling interest members. Net cash provided by financing activities was $1.4 million in 2016 as compared to net cash provided by financing activities of $2.7 million in 2015, a decrease of approximately $1.3 million. The change was driven primarily by a $1.5 million change related to the accounting for additional tax benefits for employee share-based payment awards, which in 2016 were recorded as income tax benefit in earnings as compared to 2015, when they were carried on the balance sheet and classified as part of cash provided by financing activities.

Our financial plan for 2018 indicates that our available cash and cash equivalents, together with cash from operations and borrowings expected to be available under our revolving line of credit, will be sufficient to fund our operations for the foreseeable future. Additionally, we would consider additional acquisitions if we felt they were consistent with our strategic direction. However, our actual results may differ from this plan, and we may be required to consider alternative strategies. We may be required to raise additional capital in the future. If necessary, we expect to raise these additional funds through the increased sale of customer leases, the sale of equity securities or the issuance of new term debt. There is no guarantee that additional capital will be available from these sources on acceptable terms, if at all, and certain of these sources may require approval by existing lenders. See "Risk Factors" in Item 1A of this Form 10-K for a discussion of some of the factors that affect our capital raising alternatives.

Effect of currency translation on cash

Net effect of foreign currency translations on cash changed $126 thousand to a $74 thousand positive impact in 2017 as compared to a $52 thousand negative impact in 2016. The net effect of foreign currency translation on cash changed $9 thousand to a $52 thousand negative impact in 2016 from a $43 thousand negative impact in 2015. These effects are related to changes in exchange rates between the US Dollar and the Swiss Franc, which is the functional currency of our Swiss subsidiary.

Off Balance Sheet Arrangements

We have no off balance sheet arrangements or variable interest entities.

-42-

Contractual Obligations

The Company has not entered into any transactions with unconsolidated entities whereby the Company has financial guarantees, subordinated retained interests, derivative instruments, or other contingent arrangements that expose the Company to material continuing risks, contingent liabilities, or any other obligation under a variable interest in an unconsolidated entity that provided financing, liquidity, market risk or credit risk support to the Company, or engages in leasing, hedging or R&D services with the Company.

Purchase obligations represent contractual agreements to purchase goods or services that are legally binding; specify a fixed, minimum or range of quantities; specify a fixed, minimum, variable, or indexed price provision; and specify approximate timing of the transaction.

The following table presents certain future payments due by the Company as of December 31, 2017, and excludes amounts already recorded on the Consolidated Balance Sheet, except for our line of credit (in thousands):



	Total		Less Than 1 Year		1 - 3 Years		4 - 5 Years		After 5 Years

Net Operating Loss Carryforwards

As of December 31, 2017, we had a net domestic operating loss carryforward (“NOL”) and domestic research and development tax credit carryforward. See Note 3 - Income Taxes in the accompanying notes to the consolidated financial statements for additional information regarding our carryforwards.

Recent Accounting Pronouncements

From time to time, the Financial Accounting Standards Board ("FASB") or other standard setting bodies issue new accounting pronouncements. Updates to the FASB Accounting Standards Codification ("ASC") are communicated through issuance of an Accounting Standards Update ("ASU"). Unless otherwise discussed, we believe that the impact of recently issued guidance, whether adopted or to be adopted in the future, is not expected to have a material impact on our Consolidated Financial Statements upon adoption.

To understand the impact of recently issued guidance, whether adopted or to be adopted, please review the information provided in Note 1- Operations and Summary of Significant Accounting Policies to our Consolidated Financial Statements included in Item 8 of this Form 10-K.

-43-


Item 7A.	Quantitative and Qualitative Disclosures about Market Risk

Market risk represents the risk of loss that may impact the financial position, results of operations or cash flows due to adverse changes in financial and commodity market prices and rates. We are exposed to market risk in the areas of changes in United States and foreign interest rates and changes in foreign currency exchange rates as measured against the United States dollar. These exposures are directly related to our normal operating and funding activities.

Interest Rate Risk

At December 31, 2017, there was approximately $6.0 million outstanding on our revolving credit facility with Chase. We had no interest rate hedge transactions in place on December 31, 2017. We completed an interest rate risk sensitivity analysis based on the above and an assumed one-percentage point increase in interest rates would have an approximate $60 thousand negative impact on our pre-tax earnings based on our outstanding balances as of December 31, 2017.

Foreign Currency Risk

Foreign currency risk may impact our results of operations. In cases where we purchase inventory in one currency and sell corresponding products in another, our gross margin percentage is typically at risk based on foreign currency exchange rates. In addition, in cases where we may be generating operating income in foreign currencies, the magnitude of such operating income when translated into U.S. dollars will be at risk based on foreign currency exchange rates. We had no foreign currency hedge transactions in place on December 31, 2017. We do not consider foreign currency risk to be material to our business.

OPINIONS ON THE CONSOLIDATED FINANCIAL STATEMENTS AND INTERNAL CONTROL OVER FINANCIAL REPORTING

We have audited the accompanying consolidated balance sheets of Heska Corporation and Subsidiaries (the "Company") as of December 31, 2017 and 2016, and the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows, for each year in the three‑year period ended December 31, 2017, and the related notes (collectively referred to as the "financial statements"). We have also audited the Company's internal control over financial reporting as of December 31, 2017, based on the criteria established in Internal Control ‑ Integrated Framework: (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO").

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each year in the three‑year period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control ‑ Integrated Framework: (2013) issued by COSO.

BASIS FOR OPINIONS

The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's financial statements and an opinion on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the US federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Heska Corporation and its wholly-owned subsidiaries ("Heska", the "Company", "we" or "our") sell veterinary and animal health diagnostic and specialty products. Our offerings include point of care diagnostics laboratory instruments and supplies, digital imaging diagnostics products, software and services, vaccines, local and cloud-based data services, allergy testing and immunotherapy, and single-use offerings such as in-clinic diagnostic tests and heartworm preventive products. Our core focus is on supporting veterinarians in the canine and feline healthcare space.

Basis of Presentation and Consolidation

Our consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries since their respective dates of acquisitions. All intercompany accounts and transactions have been eliminated in consolidation. Where our ownership of a subsidiary was less than 100%, the non-controlling interest is reported on our consolidated balance sheets. The non-controlling interest in our consolidated net income is reported as "Net income (loss) attributable to non-controlling interest" on our consolidated statements of income. Our consolidated financial statements are stated in United States dollars and have been prepared in accordance with accounting principles generally accepted in the United States ("US GAAP").

Reclassification

To maintain consistency and comparability, certain amounts in the financial statements have been reclassified to conform to current year presentation.

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates are required when establishing the allowance for doubtful accounts and the provision for excess or obsolete inventory, in determining future costs associated with warranties provided, in determining the period over which our obligations are fulfilled under agreements to license product rights and/or technology rights, evaluating long-lived and intangible assets for impairment, estimating the useful lives of equipment under leasing arrangements, determining the allocation of purchase price under purchase accounting, estimating the expense associated with the granting of stock options, and in determining the need for, and the amount of, a valuation allowance on deferred tax assets.

Concentration of Credit Risk

Financial instruments that potentially subject us to a concentration of credit risk consist of cash and cash equivalents and accounts receivable. We maintain the majority of our cash and cash equivalents with financial institutions that management believes are creditworthy in the form of demand deposits. We have no significant off-balance-sheet concentrations of credit risk such as foreign exchange contracts, options contracts or other foreign currency hedging arrangements. Our accounts receivable balances are due largely from distribution partners, domestic veterinary clinics and individual veterinarians and other animal health companies.

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

We have established an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical trends, and other information.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are recorded at net realizable value. From time to time, our customers are unable to meet their payment obligations. We continuously monitor our customers' credit worthiness and use our judgment in establishing a provision for estimated credit losses based upon our historical experience and any specific customer collection issues that we have identified. While such credit losses have historically been within our expectations and the provisions established, there is no assurance that we will continue to experience the same credit loss rates that we have in the past. A significant change in the liquidity or financial position of our customers could have a material adverse impact on the collectability of accounts receivable and our future operating results.

Changes in allowance for doubtful accounts are summarized as follows (in thousands):



	Years Ended December 31,
	2017			2016			2015
Balances at beginning of period	$	237		$	189		$	216
Additions - charged to expense	168			163			83
Deductions - write offs, net of recoveries	(190		)	(115		)	(110		)
Balances at end of period	$	215		$	237		$	189

Cash and Cash Equivalents

Cash and cash equivalents are stated at cost, which approximates market value, and include short-term, highly liquid investments with original maturities of less than three months. We valued our Euro and Japanese Yen cash accounts at the spot market foreign exchange rate as of each balance sheet date, with changes due to foreign exchange fluctuations recorded in current earnings. We held 1,077,787 and 2,778,614 Euros at December 31, 2017 and 2016, respectively. We held 0 and 1,252,221 Yen at December 31, 2017 and 2016, respectively. We held 80,459 and 172,743 Swiss Francs at December 31, 2017 and 2016, respectively. We held 0 and 26,477 Canadian Dollars at December 31, 2017 and 2016, respectively. The majority of our cash and cash equivalents are held at US-based or Swiss-based financial institutions in accounts not insured by governmental entities.

Fair Value of Financial Instruments

Our financial instruments consist of cash and cash equivalents, short-term trade receivables and payables and the Company's revolving line of credit. The carrying values of cash and cash equivalents and short-term trade receivables and payables approximate fair value because of the short-term nature of the instruments. The fair value of our line of credit balance is estimated based on current rates available for

-54-

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

similar debt with similar maturities and collateral, and at December 31, 2017 and 2016, approximates the carrying value due primarily to the floating rate of interest on such debt instruments.

Inventories

Inventories are stated at the lower of cost or net realizable value using the first-in, first-out method. Inventory we manufacture includes the cost of material, labor and overhead. If the cost of inventories exceeds estimated net realizable value, provisions are made to reduce the carrying value to estimated net realizable value.

Inventories, net consist of the following (in thousands):



	December 31,
	2017			2016
Raw materials	$	18,465		$	10,807
Work in process	4,296			3,820
Finished goods	11,465			7,087
Allowance for excess or obsolete inventory	(1,630		)	(1,319		)
	$	32,596		$	20,395

Property and Equipment

Property and equipment is stated at cost, net of accumulated depreciation. The costs of additions and improvements are capitalized, while maintenance and repairs are charged to expense as incurred. When an item is sold or retired, the cost and related accumulated depreciation is relieved, and the resulting gain or loss, if any, is recognized in the consolidated statements of income. We provide for depreciation primarily using the straight-line method by charges to income in amounts that allocate the cost of property and equipment over their estimated useful lives as follows:



Asset Classification	Estimated Useful Life
Building	10 to 20 years
Machinery and equipment	3 to 15 years
Leasehold and building improvements	7 to 15 years

We capitalize certain costs incurred in connection with developing or obtaining software designated for internal use based on three distinct stages of development. Qualifying costs incurred during the application development stage, which consist primarily of internal payroll and direct fringe benefits and external direct project costs, including labor and travel, are capitalized and amortized on a straight-line basis over the estimated useful life of the asset, which range from three to five years. Costs incurred during the preliminary project and post-implementation and operation phases are expensed as incurred. These costs are general and administrative in nature and related primarily to the determination of performance requirements, data conversion and training.

Goodwill, Intangible and Other Long-Lived Assets

We assess goodwill for impairment annually, at the reporting unit level, in the fourth quarter and whenever events or circumstances indicate impairment may exist. In evaluating goodwill for impairment, we have the option to first assess the qualitative factors to determine whether it is more likely than not that the estimated fair value of the reporting unit is less than its carrying amount as a basis for determining whether it

-55-

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

is necessary to perform the comparison of the estimated fair value of the reporting unit to the carrying value. The more-likely-than-not threshold is defined as having a likelihood of more than 50 percent. If, after assessing the totality of events or circumstances, we determine that is it more likely than not that the estimated fair value of a reporting is less than its carrying amount, we would then estimate the fair value of the reporting unit and compare it to the carrying value. If the carrying value exceeds the estimated fair value we would recognize an impairment for the difference; otherwise, no further impairment test would be required. In contrast, we can opt to bypass the qualitative assessment for any reporting unit in any period and proceed directly to quantitative analysis. Doing so does not preclude us from performing the qualitative assessment in any subsequent period.

In the fourth quarter of 2017, we performed a qualitative assessment of the goodwill residing within the assets of our CCA segment, also determined to be a reporting unit, and determined that no indications of impairment existed.

Intangible assets are valued based on estimates of future cash flows and amortized over their estimated useful lives. We continually evaluate whether events and circumstances have occurred that indicate the remaining estimated useful life of intangible assets as well as other long-lived assets may warrant revision, or that the remaining balance of these assets may not be recoverable. When deemed necessary, we complete this evaluation by comparing the carrying amount of the assets with the estimated undiscounted future cash flows associated with them. If such evaluations indicate that the future undiscounted cash flows of amortizable long-lived assets are not sufficient to recover the carrying value of such assets, the assets are adjusted to their estimated fair values.

The estimation of useful lives and expected cash flows requires us to make significant judgments regarding future periods that are subject to some factors outside of our control. Changes in these estimates can result in significant revisions to our carrying value of these assets and may result in material charges to our results of operations.

Revenue Recognition


•	Persuasive evidence of an arrangement exists;


•	Delivery has occurred or services rendered;


•	Price is fixed or determinable; and


•	Collectability is reasonably assured.

-56-

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

Revenue from our subscription agreements is recognized based on the length of the agreements that are signed by our customers. Among other factors, the length of the agreement determines whether a subscription is considered an operating lease or capital lease. Our capital leases qualify for sales-type lease treatment. For subscription agreements that are considered operating leases, we recognize revenue of our subscriptions ratably over the term of the agreement. The equipment is transferred from inventory to property, plant and equipment and depreciated into cost of revenue over the term of the agreement, based on the assets’ useful life. Revenue from subscription agreements that are sales-type (capital) leases is recognized, along with the associated cost of the equipment, at the time of placement in our customer’s location. The amount of revenue recognized at the time of lease inception is based on, along with other factors, observable prior sales prices of similar equipment sold by us over the prior twelve months, relative to total contract value. We record a short and long-term capital lease receivable related to sales-type leases.

Recording revenue from the sale of products involves the use of estimates and management's judgment. We must make a determination at the time of sale whether the customer has the ability to make payments in accordance with arrangements. While we do utilize past payment history, and, to the extent available for new customers, public credit information in making our assessment, the determination of whether collectability is reasonably assured is ultimately a judgment decision that must be made by management. We must also make estimates regarding our future obligations relating to returns, rebates, allowances and similar other programs.

Stock-based Compensation

Stock-based compensation expense is measured at the grant date based upon the estimated fair value of the portion of the award that is ultimately expected to vest and is recognized as expense over the applicable vesting period of the award generally using the straight-line method.

-57-

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

Advertising Costs

Advertising costs are expensed as incurred and are included in sales and marketing expenses. Advertising expenses were $0.2 million for each of the years ended December 31, 2017 and 2016, and $0.1 million for the year ended December 31, 2015.

Income Taxes

The Company records a current provision for income taxes based on estimated amounts payable or refundable on tax returns filed or to be filed each year. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates, in each tax jurisdiction, expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates, including the current year impact of the enacted 21% US corporate income tax rate under the Tax Cuts and Jobs Act, is recognized in operations in the period that includes the enactment date. The overall change in deferred tax assets and liabilities for the period measures the deferred tax expense or benefit for the period. Deferred tax assets are reduced by a valuation allowance based on a judgmental assessment of available evidence if the Company is unable to conclude that it is more likely than not that some or all of the deferred tax assets will be realized.

Earnings Per Share

Basic earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued.

Foreign Currency Translation

The functional currency of our Swiss subsidiary is the Swiss Franc. Assets and liabilities of our Swiss subsidiary are translated using the exchange rate in effect at the balance sheet date. Revenue and expense accounts and cash flows are translated using an average of exchange rates in effect during the period. Cumulative translation gains and losses are shown in the consolidated balance sheets as a separate component of stockholders' equity. Exchange gains and losses arising from transactions denominated in foreign currencies (i.e., transaction gains and losses) are recognized as a component of other income (expense) in current operations, as are exchange gains and losses on intercompany transactions expected to be settled in the near term.

Taxes Collected from Customers

In the course of doing business we collect various taxes from customers including, but not limited to, sales taxes. It is our policy to record revenue net of taxes collected from customers in our consolidated statements of income.

Shipping and Handling Costs

Amounts billed to customers related to shipping and handling are classified as revenue. Shipping and handling costs incurred by us for the delivery of products to customers are classified as cost of revenue.

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

Warranty Costs

The Company generally provides for the estimated cost of hardware and software warranties in the period the related revenue is recognized. The Company assesses the adequacy of its accrued warranty liabilities and adjusts the amounts as necessary based on actual experience and changes in future estimates. Should product failure rates differ from our estimates, actual costs could vary significantly from our expectations.

Adoption of New Accounting Pronouncements

In May 2017, the Financial Accounting Standards Board ("FASB") issued ASU 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting.” ASU 2017-09 was issued to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718 to a change in the terms or conditions of a share-based payment award. ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under Topic 718. The amendments in ASU 2017-09 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period. The amendments in ASU 2017-09 should be applied prospectively to an award modified on or after the adoption date. Heska adopted the new guidance in its second quarter of fiscal year 2017.

In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment,” to simplify financial reporting by eliminating the need to determine the fair value of individual assets and liabilities of a reporting unit to measure goodwill impairment. Under ASU 2017-04, an entity should perform its goodwill impairment test by comparing the fair value of the reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, up to the amount of goodwill allocated to that reporting unit. The new guidance effectively eliminates “Step 2” from the previous goodwill impairment test. ASU 2017-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. Heska adopted the new guidance in its fourth quarter of fiscal year 2017 when it performed its annual goodwill impairment test as of December 15, 2017.

Accounting Pronouncements Not Yet Adopted

In February 2018, the FASB issued ASU 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”. The ASU permits companies to elect a reclassification of disproportionate tax effects in accumulated other comprehensive income (AOCI) caused by the Tax Cuts and Jobs Act of 2017 to retained earnings. The ASU also requires additional disclosures. This update is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, with early adoption permitted. We are currently evaluating the effect of this ASU on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments – Credit Losses (Topic 326)", which require that financial assets measured at amortized cost be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The amendments in this update are effective for

-59-

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

fiscal years beginning after December 15, 2019 and interim periods within those annual periods. Early adoption for fiscal year beginning after December 15, 2018 is permitted.

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)", which supersedes ASC 840, Leases, and creates a new topic, ASC 842, Leases. This update requires lessees to recognize a lease liability and a lease asset for all leases, including operating leases, with a term greater than 12 months on its balance sheet. The update also expands the required quantitative and qualitative disclosures surrounding leases. The accounting for lessors does not fundamentally change except for changes to conform and align guidance to the lessee guidance as well as to the new revenue recognition guidance in ASU 2014-09. This update is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. This update will be applied using a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. We are currently evaluating the effect of this update on our consolidated financial statements.

Heska assessed the impact that the adoption of ASC 606 is expected to have on its Consolidated Financial Statements by analyzing its current portfolio of customer contracts and various revenue streams, including a review of historical accounting policies and practices to identify potential differences in applying the guidance of ASC 606. Heska also performed a comprehensive review of its current processes and systems to determine and implement changes required to support the adoption of ASC 606 on January 1, 2018.

Based on review of customer contracts within our Core Companion Animal ("CCA") segment, Heska has determined the timing of revenue recognition of our product sales, which includes upfront equipment sales and sales of consumables, will continue to be recognized as it is currently, generally upon shipment of products. Also included within CCA are our subscription agreements, which contain a lease of equipment, for which rental income will continue to be recognized under ASC 840, Leases, unless the equipment is considered a sales-type lease, which revenue will be recognized under ASC 606 at the point of sale.

-60-

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

to be recognized as it is currently - generally upon shipment or acceptance by our customer. Heska assessed the over-time criteria within ASC 606 and concluded that because products within this segment have no alternative use to Heska as Heska is contractually prohibited to redirect the product to other customers, Heska does not have right to payment for performance to date and therefore, point in time recognition is appropriate.

Often our contracts contain multiple performance obligations to which the transaction price must be allocated. The objective when allocating the transaction price is to allocate the transaction price to each performance obligation (or distinct good or service) in an amount that depicts the consideration to which the entity expects to be entitled in exchange for transferring the promised goods or services to the customer. To accomplish this objective, Heska will allocate transaction price on a relative standalone selling price basis (SSP) and where SSP is not readily observable, Heska will generally utilize expected cost-plus-a-margin approach. All of the individual performance obligations, including equipment, consumables, and services are sold separately, and therefore, observable prices are available.

Because a significant number of Heska’s customers are under noncancelable contracts for periods extending beyond one year with the delivery of goods and services occurring throughout the duration, Heska anticipates recording an asset related to the prepayment of such contract acquisition costs. In addition, ASC 606 states that "an asset recognized in accordance with the incremental costs of obtaining a contract shall be amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates." Because a significant number of Heska’s customers are under noncancelable contracts for periods extending beyond one year with the delivery of goods and services occurring throughout the duration, Heska anticipates recording an asset related to the prepayment of such contract acquisition costs.

We expect the impact of the adoption of the new standard will result in an adjustment to the recognition of software support revenue, which historically has been a separate element however this has been deemed to be an immaterial promise and therefore, previously deferred revenue relating to software support will be recognized at point of sale along with the equipment and embedded software. The adoption of the new standard will also impact the recognition of sales commissions. Previously, sales commissions were expensed when the underlying contract was executed, which will now be recognized as a cost to acquire a contract and amortized over its useful life. Finally, the new standard will impact the recognition of revenue associated with certain bill and hold arrangements. Previously, we deferred revenue recognition until shipment, which will now be recognized upon customer acceptance. We are finalizing the quantitative impact of these changes.

2. ACQUISITION AND RELATED PARTY ITEMS

Cuattro Veterinary, LLC

On May 31, 2016, the Company closed a transaction (the "Merger") to acquire Cuattro Veterinary, LLC ("Cuattro International") from Kevin S. Wilson, and all of the members of Cuattro International (the "Members"). Pursuant to the Merger, the Company issued 175,000 shares of the Company’s common stock, $0.01 par value per share (the "Common Stock"), to the Members on the Closing Date, at an aggregate value equal to approximately $6.3 million based on the adjusted closing price per share of the Common Stock as reported on the Nasdaq Stock Market on the Merger closing date. These shares were issued to the Members in a private placement in reliance upon an exemption from the registration requirements of the Securities Act of 1933, as amended, pursuant to Section 4(a)(2) thereof and the safe harbor provided by Rule 506 of Regulation D promulgated thereunder. Effective on the Merger closing date, each of the Members executed lock-up agreements with the Company that restricted their ability to sell any of the shares of Common Stock received in the Merger until 180 days after the Merger closing date. In addition, the Company assumed approximately $1.5 million in debt as part of the transaction.

Cuattro Veterinary USA, LLC

On February 24, 2013, the Company acquired a 54.6% interest in Cuattro Veterinary USA, LLC (the "Acquisition"), which was subsequently renamed Heska Imaging US, LLC ("US Imaging"). The remaining minority position (45.4)% in US Imaging was subject to purchase by Heska under performance-based puts and calls following the audit of our financial statements for 2016 and 2017. The required performance criteria were met in 2016, we considered notice given on March 3, 2017 that the put option was being exercised and on May 31, 2017, we delivered $13.8 million in cash to obtain the remaining minority position in US Imaging.

Prior to the purchase of the minority position (the "Imaging Minority"), Shawna M. Wilson, Clint Roth, DVM, Steven M. Asakowicz, Rodney A. Lippincott, Kevin S. Wilson and Cuattro, LLC owned approximately 29.75%, 8.39%, 4.09%, 3.07%, 0.05% and 0.05% of US Imaging, respectively. Kevin S. Wilson is the Chief Executive Officer and President of the Company and the spouse of Shawna M. Wilson. Steven M. Asakowicz serves as Executive Vice President, Companion Animal Health Sales for the Company. Rodney A. Lippincott serves as Executive Vice President, Companion Animal Health Sales for the Company. On April 3, 2017, and in accordance with the terms of its Operating Agreement, US Imaging distributed $2.1 million based on past operating performance, including $1.0 million to its minority interest members. As of December 31, 2017, US Imaging accrued an additional $0.3 million distribution, including $0.1 million to its minority interest members.

3. INCOME TAXES

Income Taxes

As of December 31, 2017, the Company had a domestic federal net operating loss carryforward ("NOL"), of approximately $94.0 million and a domestic research and development tax credit carryforward of approximately $0.4 million. Our federal NOL is expected to expire as follows if unused: $88.0 million in 2018 through 2022, $5.5 million in 2024 and 2025 and $0.5 million in 2027 and later. The Tax Cuts and Jobs Act repealed the corporate alternative minimum tax credit and made refundable all carryforward amounts in years 2018-2021. As a result, the alternative minimum tax credit of $0.5 million has been reclassified from a deferred tax asset to a non-current federal income tax asset.

The Company is subject to income taxes in the US federal jurisdiction, and various foreign, state and local jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. In the United States, the tax years 2014 - 2016 remain open to examination by the Internal Revenue Service and the tax years 2013 - 2016 remain open for various state taxing authorities.

Cash paid for income taxes for the years ended December 31, 2017, 2016, and 2015 was $213 thousand, $357 thousand and $55 thousand, respectively.

The Company's income tax expense (benefit) relating to income (loss) for the periods presented differs from the amounts that would result from applying the federal statutory rate to that income (loss) as follows:

In 2017, we had total income tax expense of $8.91 million, including $8.86 million in domestic deferred income tax expense, a non-cash expense, and $0.05 million in current income tax expense. In 2016, we had total income tax expense of $4.3 million, including $3.9 million in domestic deferred income tax expense, a non-cash expense, and $0.4 million in current income tax expense. In 2015, we had total income tax expense of $2.9 million, including $1.3 million in domestic deferred income tax expense, a non-cash expense, and $1.6 million in current income tax expense. The overall increase in tax expense in 2017 from 2016 was due to the re-measurement of our deferred tax assets (including the valuation allowance) due to the US Tax Cuts and Jobs Act, offset by the reduction of tax expense from stock based compensation deductions. Income tax expense increased in 2016 from 2015 as a result of higher income before taxes in 2016.

ASC 740 provides detailed guidance for the financial statement recognition, measurement and disclosure of uncertain tax positions recognized in the financial statements. Tax positions must meet a "more-likely-than-not" recognition threshold before a benefit is recognized in the financial statements. As of December 31, 2017, the Company has not recorded a liability for uncertain tax positions. The Company would recognize interest and penalties related to uncertain tax positions in income tax (benefit)/expense. No interest and penalties related to uncertain tax positions were accrued at December 31, 2017.

US Tax Reform

On December 22, 2017, the tax legislation commonly known as the US Tax Cuts and Jobs Act was signed into law (the “Act”). This enactment resulted in a number of significant changes to US federal income tax law for US corporations. Most notably, the statutory US federal corporate income tax rate was changed from 35% to 21% for corporations. In addition to the change in the corporate income tax rate, the Act further introduced a number of other changes including a one-time transition tax via a mandatory deemed repatriation of post-1986 undistributed foreign earnings and profits; the introduction of a tax on global intangible low-taxed income (“GILTI”) for tax years beginning after December 31, 2017; the further limitation of the deductibility of share-based compensation of certain highly compensated employees; and the repeal of the corporate alternative minimum tax; amongst other things.

Shortly after enactment, the Security and Exchange Commission ("SEC") issued SAB 118, which provides guidance on accounting for the new legislation. Under SAB 118, an entity should recognize amounts for which accounting can be completed. Where accounting under ASC 740 is incomplete relative to

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

certain income tax effects of tax reform, the entity should recognize provisional amounts and adjust such amounts as more information becomes available and disclose this information in its financial statements. The measurement period under SAB 118 is one year from date of enactment (with the approach being similar to business combinations).

Heska has determined the estimated tax impact of the Act by using the most reliable data available in accordance with SAB 118. Specifically, at the time the estimated tax reform impact was performed, only the Final Bill itself and Notice 2018-07 had been released to provide guidance. Therefore, reasonable approaches and considerations were performed in estimating the overall tax reform impact. Further refinement will be made to this estimation as the IRS provides further guidance prior to the filing of the Company’s 2017 income tax returns. The ultimate impact of the Act may differ from this year-end estimate due to changes in interpretations and assumptions, guidance that may be issued by various US authorities and standard setting bodies, and actions the Company may take as a result of the new provisions. The Company will refine these estimates during the one year measurement period in accordance with SAB 118.

The items below outline the 2017 financial statement considerations associated with the most material provisions of the Act impacting the Company. This list is not intended to be inclusive of all provisions included in the Act nor all impacts to the Company as a result of the Act.

•

The Act reduces the US corporate income tax rate to 21% for tax years beginning after December 31, 2017. The Company’s deferred tax balances were re-measured at 21% as of December 31, 2017. The total impact of the US tax rate decrease resulted in a one-time tax expense of $5.9 million (i.e., the write down of deferred tax asset balances and the valuation allowance.). The large amount of federal NOLs, offset against the valuation allowance thereon, were included in this re-measurement, acting as a significant driver in the large adjustment.

•

The Act imposes a one-time transition tax associated with the deemed mandatory repatriation of accumulated, and previously undistributed, foreign earnings. The Company has considered estimates of earnings and profits (E&P) as prepared and maintained for US income tax reporting and performed other procedures consistent with current guidance, in arriving at the current transition tax estimate of $38 thousand. The Company will pay this tax liability in the year it is initially assessed and will not elect to pay over the optional eight-year period.

•

GILTI (Global Intangible and Low Taxed Income) is not expected to apply to the Company as it has been historically subject to full inclusions of Subpart F income, which is excluded from “tested income” for GILTI purposes. This will be monitored going forward to ensure proper inclusion if necessary. If indeed levied, the Company will likely elect to treat such GILTI inclusion as a period expense, not a deferred tax liability.


•	Corporate AMT is repealed for tax years beginning after December 31, 2017. For this reason, the remaining AMT credit carryforward has been re-classified in the tax provision from a deferred tax asset to a long term receivable. This change reflects the Act’s provision that AMT credits become refundable over time beginning in 2018.

We previously considered the earnings in our non-US subsidiaries to be indefinitely reinvested and, accordingly, recorded no deferred income taxes for the year ended December 31, 2016. As of December 31, 2017, Heska is no longer asserting indefinite reinvestment under the exception noted in ASC 740-30-25-3, which states that the presumption that all undistributed earnings will be transferred to the parent entity may be overcome, and no income taxes shall be accrued by the parent entity. Prior to the Transition Tax, we had an excess of the amount for financial reporting over the tax basis in our foreign subsidiaries. While the Transition Tax resulted in the reduction of the excess of the amount for financial reporting over the tax basis

in our foreign subsidiaries and subjected undistributed foreign earnings to an estimated $.02 million of tax which has been provisionally recorded, an actual repatriation from our non-US subsidiaries could still be subject to additional foreign withholding taxes and US state taxes. As such, for those investments from which we were able to make a reasonable estimate of the tax effects of such repatriation, we have recorded a provisional estimate for withholding and state taxes as a deferred tax liability of $.05 million. We will record the tax effects of any change in our prior assertion with respect to these investments, and disclose any unrecognized deferred tax liability for temporary differences related to our foreign investments, if practicable, in the period that we are first able to make a reasonable estimate, no later than December 2018.

4. LEASES

In our CCA segment, primarily related to our point of care laboratory products, the Company enters into sales-type (capital) and operating leases as part of our subscription agreements. Detail of scheduled minimum lease receipts are as follows in the years ended December 31, (in thousands):



Year	2018	2019	2020	2021	2022	Thereafter
Sales-type leases	$2,119	$2,288	$2,281	$2,198	$1,794	$1,004
Operating leases	1,159	933	605	148	9	—

Our cost of equipment under operating leases at December 31, 2017 and December 31, 2016, was $10.8 million and $10.5 million, before accumulated depreciation of $5.0 million and $3.7 million, and the net book value was $5.7 million and $6.8 million, respectively.

5. EARNINGS PER SHARE

Basic earnings per share ("EPS") is computed by dividing net income attributable to Heska Corporation by the weighted-average number of common shares outstanding during the period. The computation of diluted EPS is similar to the computation of basic EPS except that the numerator is increased to exclude charges that would not have been incurred, and the denominator is increased to include the number of additional common shares that would have been outstanding (using the if-converted and treasury stock methods), if securities containing potentially dilutive common shares (stock options and restricted stock units but excluding options to purchase fractional shares resulting from the Company's December 2010 1-for-10 reverse stock split) had been converted to common shares, and if such assumed conversion is dilutive.

The Company has subscription agreements whereby its instruments in inventory may be placed in a customer's location on a rental basis. The cost of these instruments is transferred to machinery and equipment and depreciated, typically over a five to seven-year period depending on the circumstance under which the instrument is placed with the customer. Total costs transferred from inventory were approximately $1.1 million, $1.8 million and $4.1 million for the years ended December 31, 2017, 2016 and 2015, respectively.

The Company has sold certain customer rental contracts and underlying assets to third parties under agreements that once the customer has met the customer obligations under the contract, ownership of the assets underlying the contract would be returned to the Company. The Company enters a debit to cash and a corresponding credit to deferred revenue at the time of these sales. Since the Company anticipates it will regain ownership of the assets underlying these sales, the Company reports these assets as part of property and equipment and depreciates these assets in accordance with its depreciation policies. The Company had $0.2 million and $0.3 million of net property and equipment related to these transactions as of December 31, 2017 and December 31, 2016, respectively, all related to Heska Imaging.

9. CAPITAL STOCK

Stock Plans

We have two stock option plans which authorize granting of stock options, restricted, and stock purchase rights to our employees, officers, directors and consultants. In 1997, the board of directors adopted the 1997 Stock Incentive Plan (the "1997 Plan") and terminated two prior stock plans. All shares that remained available for grant under the terminated plans were incorporated into the 1997 Plan, including shares subsequently canceled under prior plans. In May 2012, the stockholders approved an amendment to the 1997 Plan allowing for an increase of 250,000 shares and an annual increase through 2016 based on the number of non-employee directors serving as of our Annual Meeting of Stockholders, subject to a maximum of 45,000 shares per year. In May 2016, the stockholders approved a further amendment to the 1997 Plan to authorize an additional 500,000 shares to be available for issuance thereunder. In May 2003, the stockholders approved a new plan, the 2003 Equity Incentive Plan (the "2003 Plan"), which allows for the granting of stock options/restricted stock for up to 239,050 shares of the Company's common stock. The number of shares reserved for issuance under both plans as of December 31, 2017 was 320,039.

Stock Options

The stock options granted by the board of directors may be either incentive stock options ("ISOs") or non-qualified stock options ("NQs"). The exercise price for options under all of the plans may be no less than 100% of the fair value of the underlying common stock for ISOs or 85% of fair value for NQs. Options granted will expire no later than the tenth anniversary subsequent to the date of grant or three months following termination of employment, except in cases of death or disability, in which case the options will remain exercisable for up to twelve months. Under the terms of the 1997 Plan, in the event we are sold or merged, outstanding options will either be assumed by the surviving corporation or vest immediately.

There are four key inputs to the Black-Scholes model which we use to estimate the fair value for options which we issue: expected term, expected volatility, risk-free interest rate and expected dividends, all of which require us to make estimates. Our estimates for these inputs may not be indicative of actual future performance and changes to any of these inputs can have a material impact on the resulting estimated fair value calculated for the option. Our expected term input was estimated based on our historical experience for time from option grant to option exercise for all employees in 2017, 2016 and 2015. We treated all employees in one grouping in all three years. Our expected volatility input was estimated based on our historical stock price volatility in 2017, 2016 and 2015. Our risk-free interest rate input was determined based on the US

-71-

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

Treasury yield curve at the time of option issuance in 2017, 2016 and 2015. Our expected dividends inputs were zero in all periods as we did not anticipate paying dividends in the foreseeable future.

Weighted average assumptions used in 2017, 2016 and 2015 for each of these four key inputs are listed in the following table:



	2017	2016	2015
Risk-free interest rate	1.76%	1.76%	1.41%
Expected lives	4.8 years	4.5 years	3.4 years
Expected volatility	41%	41%	41%
Expected dividend yield	0%	0%	0%

A summary of our stock option plans, excluding options to purchase fractional shares resulting from our December 2010 1-for-10 reverse stock split, is as follows:



	Year Ended December 31,
	2017				2016				2015

The total estimated fair value of stock options granted were computed to be approximately $1.0 million, $3.2 million and $1.6 million during the years ended December 31, 2017, 2016 and 2015, respectively. The amounts are amortized ratably over the vesting periods of the options. The weighted average estimated fair value of options granted was computed to be approximately $37.35, $24.59 and $11.35 during the years ended December 31, 2017, 2016 and 2015, respectively. The total intrinsic value of options exercised was $17.7 million, $9.9 million and $4.7 million during the years ended December 31, 2017, 2016 and 2015, respectively. The cash proceeds from options exercised was $1.8 million, $1.9 million and $1.8 million during the years ended December 31, 2017, 2016 and 2015, respectively.

As of December 31, 2017, there was approximately $3.5 million of total unrecognized compensation cost related to outstanding stock options. That cost is expected to be recognized over a weighted-average period of 2.1 years with all cost to be recognized by the end of December 2019, assuming all options vest according to the vesting schedules in place at December 31, 2017. As of December 31, 2017, the aggregate intrinsic value of outstanding options was approximately $32.6 million and the aggregate intrinsic value of exercisable options was approximately $28.3 million.

Employee Stock Purchase Plan

Under the 1997 Employee Stock Purchase Plan (the "ESPP"), we are authorized to issue up to 450,000 shares of common stock to our employees, of which 419,651 had been issued as of December 31, 2017. On May 5, 2015, our shareholders approved the amendment and restatement of the ESPP, including a 75,000 share increase to 450,000 total shares authorized under the ESPP as well as changes discussed below as compared to the ESPP prior to the amendment and restatement. Employees who are expected to work at least 20 hours per week and 5 months per year are eligible to participate and can choose to have up to 10% of their compensation withheld to purchase our stock under the ESPP when they choose to withhold a whole percentage of their compensation.

Beginning on July 1, 2013, our ESPP had a 27-month offering period and three-month accumulation periods ending on each March 31, June 30, September 30 and December 31. The purchase price of stock on March 31, June 30, September 30 and December 31 was the lesser of (1) 85% of the fair market value at the time of purchase and (2) the greater of (i) 95% of the fair market value at the beginning of the applicable offering period or (ii) 65% of the fair market value at the time of purchase. In addition, participating employees may purchase shares under the ESPP at the beginning of an applicable offering period for a purchase price of stock equal to 95% of the fair market value at such time or at 5 pm on a day other than March 31, June 30, September 30 and December 31 during the applicable offering period for a purchase price of stock equal to 95% of the fair market value at purchase.

Beginning April 1, 2015, employees may elect to withhold a positive fixed amount from each compensation payment in addition to the previous approach of withholding a whole percentage of such compensation payment, with all withholding for a given employee subject to a maximum monthly amount of $2,500 following the amendment and restatement as opposed to a $25,000 maximum annual amount prior to the amendment and restatement. For offering periods beginning on or after April 1, 2015, the purchase price of stock on March 31, June 30, September 30 and December 31 is to be the lesser of (1) 85% of the fair

to Mr. Wilson following a vote of approval on the issuance by our stockholders. The shares were issued in ten equal tranches, five of which were subject to vesting based on the achievement of certain stock price targets as defined and further described in the Wilson Employment Agreement and five of which were subject to vesting based on certain "Adjusted EBITDA" targets as defined and further described in the Wilson Employment Agreement. All shares subject to vesting based on "Adjusted EBITDA" vested based on our 2014 performance. Of the five tranches based on the achievement of certain stock price targets, one vested in 2014 and the remaining four vested in 2015.

On March 17, 2015, the Company issued unvested shares to certain Executive Officers related to performance-based restricted stock grants (the "Performance Grants") and performance-based restricted stock grants related to the Company's 2015 Management Incentive Plan (the "2015 MIP Grants"). The Company issued 52,956 shares under the Performance Grants and 24,649 shares under the 2015 MIP Grants from the 1997 Plan. The Performance Grants have met the underlying performance condition based on the Company's 2015 financial performance and are to cliff vest on March 17, 2018, subject to other vesting provisions in the underlying restricted stock grant agreement. The 2015 MIP Grants were subject to the Company’s achievement of certain financial goals and other vesting provisions in the underlying restricted stock grant agreement. On March 2, 2016, the Company vested 14,364 shares related to the 2015 MIP Grants based on the respective performance criteria, including 4,788 shares withheld for tax, and canceled the remaining 10,285 shares. The compensation expense is based on the closing market price on the date of the grant.

On March 2, 2016, the Company issued 15,000 unvested shares to certain Executive Officers related to performance-based restricted stock grants as part of the Company’s 2016 Management Incentive Plan (the "2016 MIP Grants") from the 1997 Plan. Of these, 14,629 vested, 371 were forfeited, and 4,133 were withheld for tax. The 2016 MIP Grants vested during the three months ended March 31, 2017. The compensation expense is based on the closing market price on the date of the grant.

On May 1, 2017, the Company issued 2,720 shares of our Common Stock to the Company's non-employee directors from the 2003 Plan, with a subsequent grant of 567 shares to a new non-employee director on June 12, 2017 from the 2003 Plan. These grants are to vest (the "Vesting Time") in full on the latter of (i) the one year anniversary of the date of grant and (ii) the Company’s Annual Meeting of Stockholders for the year following the year of grant for the award (the "Vesting Meeting"), subject to (i) the non-employee director's continued service to the Company through the Vesting Time, unless the non-employee director’s current term expires at the Vesting Meeting in which case vesting is subject to the non-employee director’s service to the Vesting Meeting and (ii) the non-employee director not engaging in “competition”, as defined in a restricted stock grant agreement executed by the non-employee director, to the Vesting Time. The compensation expense is based on the closing market price on the date of the grant.

On May 31, 2017, the Company issued 23,700 unvested performance-based restricted stock shares to certain key employees from the 1997 Plan. The vesting of these shares is subject to the achievement of certain Company performance and market conditions and, in some instances, a service period requirement, that must be met on or before May 30, 2024. For the four tranches related to performance conditions, the compensation expense is based on the closing market price on the date of the grant, $98.66. The award is expensed when the performance condition is considered probable and taken ratably over the period in which the performance metrics are expected to be achieved. For the six tranches related to market conditions, which include stock price targets and outperformance of the S&P, the compensation expense is based on a fair value assigned to the market metric upon grant using a Monte Carlo model, weighted average value of $69.06, which remains constant throughout the vesting period, also determined within the model.

On June 15, 2017, the Company issued 6,594 unvested shares to certain Executive Officers related to performance-based restricted stock grants as part of the Company's 2017 Management Incentive Plan from

the 1997 Plan. As of December 31, 2017, all shares were forfeited and no compensation expense was recorded for the period ended December 31, 2017.

On December 1, 2017, the Company issued 45,000 unvested performance-based restricted stock shares from the 1997 Plan to Mr. Wilson. The vesting of these shares is subject to the achievement of certain Company performance and market conditions and, in some instances, a service period requirement, that must be met on or before March 31, 2025. For the three tranches (equal tranches of 9,375 restricted shares) related to performance conditions, the compensation expense is based on the closing market price on the date of the grant, $86.32. The award is expensed when the performance condition is considered probable and taken ratably over the period in which the performance metrics are expected to be achieved. For the three tranches (equal tranches of 5,625 restricted shares) related to market conditions, which include stock price targets, the compensation expense is based on a fair value assigned to the market metric upon grant using a Monte Carlo model, weighted average value of $72.95, which remains constant throughout the vesting period, which is also determined within the model.

As of December 31, 2017, there was approximately $3.2 million of total unrecognized compensation cost related to restricted stock. The Company expects to recognize this expense over a weighted average period of 1.4 years.

Restrictions on the transfer of Company stock

The Company's Restated Certificate of Incorporation, as amended (the "Certificate of Incorporation"), places restrictions (the "Transfer Restrictions") on the transfer of the Company's stock that could adversely affect the Company's ability to utilize its domestic Federal Net Operating Loss Position. In particular, the Transfer Restrictions prevent the transfer of shares without the approval of the Company's Board of Directors if, as a consequence of such transfer, an individual, entity or groups of individuals or entities would become a 5-percent holder under Section 382 of the Internal Revenue Code of 1986, as amended, and the related Treasury regulations, and also prevents any existing 5-percent holder from increasing his or her ownership position in the Company without the approval of the Company's Board of Directors. Any transfer of shares in violation of the Transfer Restrictions (a "Transfer Violation") shall be void ab initio under the Certificate of Incorporation, and the Company's Board of Directors has procedures under the Certificate of Incorporation to remedy a Transfer Violation including requiring the shares causing such Transfer Violation to be sold and any profit resulting from such sale to be transferred to a charitable entity chosen by the Company's Board of Directors in specified circumstances.

The Company holds certain rights to market and manufacture all products developed or created under certain research, development and licensing agreements with various entities. In connection with such agreements, the Company has agreed to pay the entities royalties on net product sales. Royalties of $0.3 million became payable under these agreements in the year ended December 31, 2017, and $0.4 million in each of the years ended December 31, 2016 and 2015.

The Company had rent expense of $1.6 million in each of the years ended December 31, 2017, 2016, and 2015.

From time to time, the Company may be involved in litigation relating to claims arising out of its operations. On March 12, 2015, a complaint was filed against us by Shaun Fauley in the United States District Court Northern District of Illinois alleging our transmittal of unauthorized faxes in violation of the federal Telephone Consumer Protection Act of 1991, as amended by the Junk Fax Prevention Act of 2005, as a class action seeking stated damages of the greater of actual monetary loss or five hundred dollars per violation ("Fauley Complaint"). The Company does not have insurance coverage for the Fauley Complaint. The Company intends to defend itself vigorously in this matter and at this time is unable to estimate a possible loss or a range of loss. At December 31, 2017, the Company was not a party to any other legal proceedings that were expected, individually or in the aggregate, to have a material adverse effect on our business, financial condition or operating results.

The Company's current terms and conditions of sale include a limited warranty that its products and services will conform to published specifications at the time of shipment and a more extensive warranty related to certain of its products. The Company also sells a renewal warranty for certain of its products. The typical remedy for breach of warranty is to correct or replace any defective product, and if not possible or practical, the Company will accept the return of the defective product and refund the amount paid. Historically, the Company has incurred minimal warranty costs. The Company's warranty reserve was $0.2 million and $0.4 million as of December 31, 2017 and 2016, respectively.

13. CREDIT FACILITY AND LONG-TERM DEBT

On July 27, 2017, we entered into a Credit Agreement (the "Credit Agreement") with JPMorgan Chase Bank, N.A. ("Chase"), which provides for a revolving credit facility of up to $30.0 million (the "Credit Facility"). The Credit Facility provides us with the ability to borrow up to $30.0 million, although the amount of the Credit Facility may be increased by an additional $20.0 million up to a total of $50.0 million subject to receipt of additional lender commitments and other conditions. Any interest on borrowings due is to be charged at either the (i) rate of interest per annum publicly announced from time to time by Chase at its prime rate in effect at its principal offices in New York City, subject to a floor, minus 1.65%, or (ii) the interest rate per annum equal to (a) LIBOR for the interest period in effect multiplied by (b) Chase's Statutory Reserve Rate (as defined in the Credit Agreement), plus 1.10% and payable monthly. There is an annual minimum interest charge of $60 thousand under the Credit Agreement. Borrowings under the Credit Facility are subject to certain financial and non-financial covenants and are available for various corporate purposes, including general working capital, capital investments, and certain permitted acquisitions. The Credit Agreement also permits us to issue letters of credit. The maturity date of the Credit Facility is July 27, 2020. The foregoing discussion of the Credit Facility is a summary only and is qualified in its entirety by reference to the full text of the Credit Agreement, a copy of which has been filed as an exhibit to the Company's Current Report on Form 8-K filed with the SEC on August 2, 2017. At December 31, 2017, we had $6.0 million of borrowings outstanding on this line of credit and we were in compliance with all financial covenants. In connection with the Credit Agreement, the Company incurred debt issuance costs of $120 thousand. These costs are included in other non-current assets on the Company's consolidated balance sheet, and will be amortized to interest expense ratably over the term of the agreement.

Concurrent with the Credit Agreement, we repaid all outstanding balances and closed our $15.0 million asset-based revolving line of credit with Wells Fargo, which had a maturity date of December 31, 2017. Our outstanding balance under this arrangement at December 31, 2016 was $0.7 million. Our ability to borrow under this line of credit varied based upon available cash, eligible accounts receivable and eligible inventory. On December 31, 2016, any interest on borrowings due was to be charged at a stated rate of three month LIBOR plus 2.25% and payable monthly. Under this agreement, we were required to comply with various financial and non-financial covenants, and we have made various representations and warranties under our agreement with Wells Fargo. A key financial covenant was based on a fixed charge coverage ratio, as defined in our agreement with Wells Fargo. Failure to comply with any of the covenants, representations or warranties could result in our being in default on the loan and could cause all outstanding amounts payable to Wells Fargo to become immediately due and payable or impact our ability to borrow under the agreement.

For each of the quarters included in the Company’s Form 10-Qs for the year ended December 31, 2017, revenue and cost of revenue related to CCA distributor sales were overstated by $0.8 million, $0.9 million, and $1.1 million for the first, second, and third quarters, respectively. On December 31, 2017, an adjustment was made to reduce cost of revenue and full year revenue by $2.8 million, resulting in no impact on gross profit or net income and an increase to gross profit percentage of 1.3% for the full year and 1.2%, 1.2%, and 1.6% for the first, second, and third quarters, respectively. Management considered the impact to current and past financial statements under the SEC’s authoritative guidance on materiality and determined that the issue was not material, and therefore, the prior quarters’ Form 10-Qs were not amended. Impacts to all periods in 2017, 2016 and 2015 were immaterial.

Based on this evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time period specified in the SEC's rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding disclosure.

Management's Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the Company conducted an evaluation of the effectiveness of its internal control over financial reporting based on criteria set forth in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, the Company's management has concluded that the Company's internal control over financial reporting was effective as of December 31, 2017.

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 risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Accordingly, even an effective system of internal control will provide only reasonable assurance that the objectives of the internal control system are met.

EKS&H LLLP, an independent registered public accounting firm, has audited our Consolidated Financial Statements included in this Form 10-K, and as part of the audit, has issued a report, included herein, on the effectiveness of our internal control over financial reporting as of December 31, 2017.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the fourth quarter of 2017 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
