HeskaView+TM is a Picture Archival and Communications Systems (PACS) for web or local viewing, reporting, planning and email sharing of studies on Internet devices, including personal computers, tablet devices and smartphones. SupportCloudTM 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, CloudbankTM and SupportCloudTM is supported by the acquisition software used in the equipment we sell. On December 21, 2018, we closed on the purchase of the acquisition software previously provided by Cuattro in the amount of $8.2 million and terminated a supply and license agreement. See Note 3 to the financial statements included under Item 8 of this Annual Report on Form 10-K for related party and acquisition disclosures.

HeskaView and Heska’s Data Capture Utility (DCU) are modern and intuitively operated practice information software applications for point of care devices. The HeskaView software can be used as independent practice information reporting software for Heska analyzers. HeskaView and the DCU can be used as a middleware to bi-directionally connect Heska’s analyzers to a wide variety of Veterinary Practice Management Software platforms used throughout North America.

scil vIP® is a modern and intuitively operated practice information software for point of care devices. The software can be used as independent practice information software or as middleware to connect POC equipment throughout Europe. It further provides a web interface allowing the users to access the software even more easily.

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.

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 U.S. 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. 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.

-5-

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 U.S. We also sell products to screen for the presence of allergen-specific IgE to these customers. 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.

Other Vaccines and Pharmaceuticals ("OVP")

We developed a line of bovine vaccines that are licensed by the U.S. Department of Agriculture ("USDA"). In January 2015, we signed a long-term Master Supply Agreement related to these vaccines with Eli Lilly operating through Elanco.

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.

Marketing, Sales and Customer Support

We currently market our products to veterinarians through an outside field organization, a telephone sales force and independent third-party distributors, as well as through trade shows, print advertising and through other distribution relationships, such as Merck Animal Health in the case of our heartworm preventive. As of December 31, 2020, our customer facing sales, installed base support and utilization organization consisted of 144 and 124 individuals in various parts of our North America and International segments, respectively.

Veterinarians may obtain our products directly from us or indirectly through others. All of our products ultimately are sold primarily to or through veterinarians. The acceptance of our products by veterinarians is critical to our success. Internationally, we market our products to veterinarians primarily through third-party veterinary diagnostic laboratories and independent third party distributors, but through our recent acquisitions of scil, Optomed and CVM, and organic efforts in Australia, we have begun to market directly.

-6-

We have a staff dedicated to customer and product support 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.

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.

Our facility in Des Moines, Iowa is a 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 products at this facility.

The OVP products for our North America segment are purchased 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 most of the products we manufacture are readily available from more than one source.

Product Development

We are committed to providing innovative products to address the 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.

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.

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 products are primarily protected through trade secret protection of, for example, our manufacturing processes in this area.

-7-

We actively seek patent protection both in the U.S. and abroad. Our issued patent portfolios primarily relate to allergy, diagnostic and detection tests, and vaccine delivery technologies. As of December 31, 2020, we owned, co-owned or had rights to 5 issued U.S. patents expiring at various dates from April 2021 to April 2024 and had 2 pending U.S. patent application. Our corresponding foreign patent portfolio as of December 31, 2020 included 7 issued patents in various foreign countries expiring at various dates from February 2021 to August 2024 and 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

While we do not experience significant seasonal fluctuations in our sales throughout the year, we generally experience higher sales in the fourth quarter due to industry trade shows and other similar activities.

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 U.S., 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 U.S. 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. 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 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.

-8-

•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.

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 U.S.

We have pursued CE Marking for imaging equipment and regulatory approval outside the U.S. based on market demographics of foreign countries. For marketing outside the U.S., 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 U.S. 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 from the Canadian Center for Veterinary Biologics, or CCVB (Canada); the Japanese Ministry of Agriculture, Forestry and Fisheries, or MAFF (Japan); the Australian Department of Agriculture, Fisheries and Forestry, or ADAFF (Australia); the Republic of South Africa Department of Agriculture, or RSADA (South Africa); the Agriculture, Fisheries and Conservation Department, or ADCD (Hong Kong); the Macau Animal Health Division of Animal Control and Inspection, or IACM (Macau); the Spanish Ministry for Agriculture, Fisheries and Food; and from the relevant regulatory authorities in certain other countries requiring such approval.

The heartworm and allergy products previously discussed which have received regulatory approval in the U.S. and/or elsewhere are summarized below:

Customer Concentration

The information concerning our significant customers included in our Risk Factors section of this Annual Report under the caption “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” is incorporated herein by reference thereto.

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") and Zoetis Inc. ("Zoetis"). Idexx has a larger veterinary product and service offering than we do and a large sales infrastructure network and a well-established brand name. Zoetis also has a large sales infrastructure network.

In our North America segment, the OVP products we manufacture 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 we do. Companies with a significant presence in the animal health market such as CEVA Santé Animale, Elanco, 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, 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.

Human Capital Resources

As of December 31, 2020, we employed approximately 602 persons, 360 of which resided in North America and 242 internationally. We employ temporary workers on a need only basis to maintain business flexibility and a dynamic workforce. We are committed to employee diversity and inclusion and the support of traditionally underrepresented groups in management. Our workforce is approximately 50% women and 50% men with 40% of our management team (defined as Director, Vice President and Executive Vice President) represented by women. In 2020, we experienced an employee turnover rate of approximately 13% globally.

We believe that the current and future success of our company’s ability to execute on its strategic initiatives is highly dependent upon our ability to recruit, retain and reward our employees. We engage in targeted recruitment strategies to fill highly skilled positions. Our employees enjoy competitive compensation plans including market rate targeted salaries, robust benefits including retirement plans and employee stock purchase plan opportunities, and the opportunity for participation in short and long term incentive programs. Our compensation philosophy is designed to provide an appealing, market-based and rewarding compensation program that encourages high personal and company performance, strong cultural and ethical behavior, and incentives aligned with shareholder interests. Our aim is to attract, engage and retain highly qualified, motivated, and creative people who will fulfill our mission to be the “voice of the pet,” while delivering on Heska goals in a healthy, honest, and sustainable manner.

We are committed to providing a workplace that protects the health and well-being of our employees. All employees are required to abide by our Code of Conduct and Ethics, company health and safety parameters and contribute to a positive and friendly company culture. Due to the COVID-19 pandemic and in consideration of our employees’ safety, in March 2020, we implemented strict work from home policies for all employees with the ability to work remotely at all of our locations. At our Des Moines, Iowa manufacturing facility, we instituted staggered start times, designated building entry/exit protocols and closed common areas to maximize “social distancing” guidelines. As of December 31, 2020, we continue to enforce these safety precautions and abide by Center for Disease Control (“CDC”) guidelines, while tentatively planning limited return to work procedures in the second half of 2021.

Our Chief Administrative Officer is responsible for developing and executing the Company’s human capital strategy and updates the Board on human capital matters.

Item 1A.Risk Factors

Risk Factors Summary

Pursuant to Item 105(b) of Regulation S-K, the following represents a summary of the principal factors that make an investment in our common stock speculative or risky. This summary does not address all of the risks that we face. Additional discussion of the risks summarized in this risk factor summary, and other risks that we face, can be found below under the heading “Risk Factors” and should be carefully considered, together with other information in this Form 10-K and our other filings with the SEC, before making an investment decision regarding our common stock.

Risks related to our business and industry

•The COVID-19 pandemic is adversely impacting consumer demand, our global supply chain and our financial and operational results.

•If the third parties that 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.

•Our Chief Executive Officer has acknowledged outside business interests which may occupy a portion of his time.

•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.

•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.

•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.

•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.

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

•We face risks associated with our international operations and our international expansion may not generate the results we anticipate.

-13-

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

•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 are currently evaluating, and we intend to pursue, acquisitions and other strategic development opportunities, which may not have desired results and could be detrimental to our financial position.

•Obtaining and maintaining regulatory approvals in order to market our products may be costly and could 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.

•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.

•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.

•Cyberattack related breaches of our information technology systems could have an adverse effect on our business.

•We may be unable to protect our stakeholders’ privacy or we may fail to comply with privacy laws.

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

•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.

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

Risks related to our common stock

•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. This volatility could affect the value of our common stock.

•Our NOL Protective Amendment could adversely impact the value and trading liquidity of our common stock.

•If securities analysts do not publish research or reports about our business, or if they downgrade our stock, the price of our stock could decline.

•We have not declared or paid any dividends on our common stock since 2012 and we do not anticipate paying any cash dividends in the foreseeable future.

•We have fewer 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 common stock on The Nasdaq Capital Market. We may also be unable to otherwise maintain our listing on The Nasdaq Capital Market.

•Provisions in our Certificate of Incorporation and bylaws and under Delaware law might discourage, delay or prevent a change of control of our company or changes in our management and, therefore, depress the trading price of our common stock.

Risks related to the outstanding Notes

•Servicing our debt will require a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial debt.

-14-

•We may not have the ability to raise the funds necessary to settle conversions of our convertible notes (the "Notes") in cash or to repurchase the Notes upon a fundamental change, and our future debt may contain, limitations on our ability to pay cash upon conversion or repurchase of the Notes.

•The conditional conversion feature of the Notes, if triggered, may adversely affect our financial condition and operating results.

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 the material factors and the possible impact of these factors on future results of 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.

Risks related to our business and industry

The COVID-19 pandemic is adversely impacting consumer demand, our global supply chain and our financial and operational results.

With the recent acquisition of scil, our worldwide operations make us vulnerable to risks from a global public health crisis, such as the COVID-19 pandemic. We expect a future adverse impact to our financial results as the pandemic spreads through domestic and foreign markets and if local governmental authorities institute or extend “shelter at home” protective measures. While the pace and ability of governmental authorities to contain the COVID-19 pandemic remains uncertain, we expect this global public health crisis to have an adverse impact on our financial results, including revenues, earnings and cash flows through at least the first half of 2021; specifically as a result of:

•Temporary closure or reduced hours of veterinary clinics where we sell our products and services, resulting in decreased visits and testing;

•Reduction in consumer discretionary spending on their pets’ health and wellbeing;

•Potential supply chain disruption caused by customs restrictions of cross border trade, and other factors related to COVID-19 pandemic;

•Potential supply chain disruption as suppliers consider focusing research and development efforts on human health away from animal health;

•Governmental orders that create an array of restrictions on our customers, our employees and the pets they serve to limit the spread of the COVID-19 pandemic;

•Lower productivity due to reduced travel, work from home policies or shelter in place orders; and

•Overall slowdown in foreign and domestic economies resulting in stagnating wage growth, reduced discretionary spending and temporary or permanent staffing layoffs.

As a result of the COVID-19 pandemic, we have implemented strict work from home policies for all employees with the ability to work remotely at all of our locations. At our Des Moines, Iowa manufacturing facility, production schedules remain on track for order fulfillment but we have instituted staggered start times, designated building entry/exit protocols and closed common areas to maximize “social distancing” guidelines. Companywide, we enacted travel restrictions. The restricted travel policies for our sales force may adversely affect our customers' ability or willingness to purchase our products and services, delay customer capital spending and reduce our ability to provide on-site customer service. While we are unable to predict the duration of the financial and operational impact due to the COVID-19 pandemic, we expect it could have

-15-

minimal adverse impact on our business through at least the first half of 2021. The COVID-19 pandemic could also have the effect of heightening other risk factors described in this report.

If third parties that 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 agreements with Merck Animal Health (“MAH”) for our canine heartworm preventive product, TRI-HEART Plus Chewable Tablets, and Elanco for certain bovine vaccines, which have been sold primarily under the Titanium and MasterGuard brands. 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. For example, in 2020, MAH failed to market, sell and support our heartworm preventive product, which resulted in depressed OVP product annual revenue in our North America segment. 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. 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.

Our Chief Executive Officer has acknowledged outside business interests which may occupy a portion of his time.

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 during 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.

Cuattro, LLC charged Heska Imaging $0, $6.0 thousand, and $4.6 million during 2020, 2019, and 2018, respectively, primarily related to digital imaging products, for which there was an underlying supply contract with minimum purchase obligations, software and services as well as other operating expenses.

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 that sell us proprietary products are FUJIFILM Corporation and Shenzen Mindray Bio-Medical Electronics Co., Ltd. We often purchase products from our suppliers under agreements that are of limited duration or potentially can be terminated on short notice subsequent to unfavorable legal action. In the case of our point of care laboratory instruments and our digital radiography solutions, post-termination,

-16-

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. 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 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 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.

-17-

•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.

•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.

•Changes to United States tariff and import/export regulations. Changes to United States trade policies, treaties and tariffs could have a material adverse effect on global trade. These changes could result in increased costs of goods imported into the United States for the Company and our third party suppliers. Our third party suppliers may limit their trade with companies in the United States, including us.

•Global human and animal health risk. Several of our suppliers have operations in areas that may be susceptible to public health emergencies that could restrict global trade generally, and our access to consumables and product, specifically. The risk of infectious disease in humans and animals may limit trade and product access with third party suppliers with companies inside and outside the United States,

-18-

including us. In particular, the use of animal bi-product may affect our consumable supply as a result of global animal health risks.

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.

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 (“CEO”) 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.

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.

We are dependent upon a number of significant customers. Revenue from Covetrus, Inc., formerly known as Henry Schein Animal Health ("Covetrus"), represented approximately 6%, 14% and 15% of our consolidated revenue for the years ended December 31, 2020, 2019 and 2018, respectively. Revenue from Merck entities, including Merck Animal Health, represented approximately 5%, 1% and 12% of our consolidated revenue for the years ended December 31, 2020, 2019 and 2018, respectively. No other customer accounted for more than 10% of our consolidated revenue for the years ended December 31, 2020, 2019 or 2018.

Covetrus represented 9% and 19% of our consolidated accounts receivable at December 31, 2020 and 2019, respectively. No other customer accounted for more than 10% of our consolidated accounts receivable at December 31, 2020 or 2019. The loss of, or material reduction in business from, any of our significant customers could adversely affect our business 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 that sell products under their own private labels. In the point-of-care diagnostic testing market, our major competitors include IDEXX Laboratories, Inc. and Zoetis Inc.. The OVP products manufactured by our North America 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 product customers. Competitors may have facilities with similar capabilities to our Des Moines, Iowa facility, which they may operate and sell at a lower unit price to customers than we sell our OVP products for, which could cause us to lose customers. Companies with a significant presence in the companion animal health market, such as CEVA Sante´ Animale, Elanco, 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 may 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 occasionally dependent on third parties and collaborative partners to 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 may 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, or at all. 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 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 products primarily to or through veterinarians. The acceptance of our products by veterinarians is critical to our success. Changes in our ability

-20-

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 that 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 consumable 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 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 who we anticipate will 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.

We face risks associated with our international operations and our international expansion may not generate the results we anticipate.

A core component of our future growth strategy is international expansion. As we continue to expand our international footprint, we will be increasingly susceptible to the risks associated with international operations including, but not limited to, the following:

•uncertain political and economic climates and fluctuations in exchange rates that may increase the volatility of foreign-based revenue and expenses;

•burdens of complying with and unexpected changes in foreign laws, accounting and legal standards, regulatory requirements, taxes, tariffs and other barriers or trade restrictions;

•lack of experience in connection with the customs, cultures, languages and sales cycle;

•reduced or altered protection for intellectual property rights; and

•data privacy laws in foreign countries, which require that data storage and processing be subject to laws different than the United States.

As a result of these and other factors, international expansion may be more difficult and not generate the results we anticipate, which could negatively impact our business.

-21-

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. Even if meritless, these disputes may require significant expenditures on our part and could entail a significant distraction to members of our management team or other key employees. For example, it took us until October 10, 2018, to reach an agreement in principle to settle the complaint that was filed against the Company by Shaun Fauley on March 12, 2015 in the United States District Court for the 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 (the “Fauley class action”). The settlement, which was approved by the court on February 28, 2019, required us, among other things, to pay $6.75 million to class members, as well as to pay attorneys’ fees and expenses to legal counsel to the class, which we paid in full on April 3, 2019. Insurance coverage may not cover any costs required to litigate a legal dispute or an unfavorable ruling or settlement. We did not have insurance coverage for the settlement arrangement regarding the Fauley class action and had to borrow under our Credit Facility to fund the settlement. A legal dispute leading to an unfavorable ruling or settlement, whether or not insurance coverage may be available for any portion thereof, could have material adverse consequences on our business. Moreover, we may have to use legal means and incur affiliated costs to secure the benefits to which we are entitled under third party agreements, 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 affected products or services. We or our collaborators or suppliers may not, however, 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 we or they are unable to obtain such licenses or if current and future licenses prove inadequate, 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, or at all.

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.

As a public company, we have incurred and will continue to incur significant legal, accounting and other expenses due to our compliance with regulations and disclosure obligations applicable to us, including compliance with the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, as well as rules implemented

-22-

by the SEC and the Nasdaq Stock Market. We prepare our financial statements in conformance with GAAP. These accounting principles are established by and are subject to interpretation by the SEC, the FASB and others which interpret and create accounting policies. These rules and regulations will continue to cause us to incur significant legal and financial compliance costs and will make some activities more time-consuming and costly. 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 require us to incur additional compliance costs, 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 $88.3 million at December 31, 2020 and $36.2 million at December 31, 2019. There can be no assurance that future goodwill impairments will not occur if projected financial results are not met, or otherwise.

We are currently evaluating, and we intend to pursue, acquisitions and other strategic development opportunities, which may not have desired results and could be detrimental to our financial position.

We continue to evaluate, and we intend to pursue, acquisitions and other strategic development opportunities, including minority investments where strategic, such as our acquisition of scil in 2020. 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. We may also diminish our cash resources or dilute stockholders in order to finance any such acquisition or other strategic transaction.

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 is likely to 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.

-23-

Obtaining and maintaining regulatory approvals in order to market our products may be costly and could 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 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 analogous or additional 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 significantly damage our business or results of operations.

-24-

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:

•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.

-25-

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

Cyberattacks are increasing in their frequency, sophistication and intensity, and have become increasingly difficult to detect and defend against, notwithstanding our ongoing evaluation of and improvements to the preventive measures we take on to reduce the risks associated with these threats based on our own experience and those observed in the broader market. 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 our Company's confidential information or assets or disrupting our Company’s ability to operate normally, could have a material adverse effect on our business. Cyberattacks may cause equipment failures, loss of information or assets, including sensitive personal information of third-party 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. The preventive actions we take on an ongoing basis to reduce the risks and mitigate the potential damages associated with cyberattacks, including protection of our systems, networks and assets and the retention of cybersecurity insurance policies, may be insufficient to repel or mitigate entirely the effects of a cyberattack.

We devote significant resources to network security, data encryption and other security measures to protect our systems and data, but these security measures cannot provide absolute security. To the extent we were to experience a breach of our systems and were unable to protect sensitive data in the wake of the breach, 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 our systems or results in the unauthorized release of Personally Identifiable Information (“PII”), our reputation and brand could be materially damaged; use of our products and services could decrease, we could suffer from reputational harm impacting sales revenue, and we could be faced with unforeseen regulatory investigation, remediation and litigation costs. Our cybersecurity insurance policies may not cover the full extent, or any, of the potential financial harm that could be caused by a breach of our systems, including in respect of theft or possible damages claims that may be brought against us by our business partners and customers in respect of any such breach.

The frequently changing attack techniques, along with the increased volume and sophistication of the attacks, create additional potential for us to be adversely impacted by this activity. This impact could result in reputational, competitive, operational or other business harm as well as management distraction, financial losses and costs, and regulatory action.

We may be unable to protect our stakeholders’ privacy or we may fail to comply with privacy laws.

The protection of customer, employee, supplier and company data is critical and the regulatory environment surrounding information security, storage, use, processing, disclosure and privacy is demanding, with the frequent imposition of new and changing requirements. In addition, our customers, employees and suppliers expect that we will protect their personal information. Any actual or perceived significant breakdown, intrusion, interruption, cyberattack or corruption of customer, employee or supplier data or our failure to comply with federal, state, local and foreign privacy laws, including the European Union’s General Data Protection Regulation (“GDPR”) and the Health Insurance Portability and Accountability Act, could result in lost sales, remediation costs, and legal liability including severe penalties, regulatory action and reputational harm. GDPR became effective in 2018, for example, and requires companies to meet new and enhanced requirements regarding the handling of personal data, including its use, protection and the rights of data

-26-

subjects to request correction or deletion of their personal data. Failure to meet GDPR requirements could result in penalties of up to 4% of worldwide revenue. Despite our efforts and investments in technology to secure our computer network, security could be compromised, confidential information could be misappropriated or system disruptions could occur. Failure to comply with the security requirements or rectify a security issue may result in fines and the imposition of restrictions on our ability to accept payment by credit or debit cards. In addition, the payment card industry (“PCI”) is controlled by a limited number of vendors that have the ability to impose changes in PCI’s fee structure and operational requirements on us without negotiation. Such changes in fees and operational requirements may result in our failure to comply with PCI security standards, as well as significant unanticipated expenses. Such failures could materially adversely affect our operating results and financial condition. Furthermore, we maintain cybersecurity insurance coverage at levels that we believe are appropriate for our business. The costs related to significant security breaches or disruptions, however, could be material and exceed the limits of the cybersecurity insurance we maintain against such risks. If the amounts of our insurance coverage are inadequate to satisfy any damages and losses in the event of a cybersecurity incident, we may have to expend significant resources to mitigate the impact of such an incident, and to develop and implement protections to prevent future incidents of this nature from occurring. Such financial exposure could have a material adverse effect on our business.

We may not be able 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, 2020, we had an accumulated deficit of $150.9 million. Relatively small differences in our performance metrics may cause us to generate an operating or net loss in future periods. Our ability to be profitable in future periods will depend, in part, on our ability to increase sales, 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 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.

-27-

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 biohazardous materials, including chemicals and infectious disease agents. 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.

Risks related to our common stock

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. This volatility could affect the value of our common stock.

Should a relatively large stockholder 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, 2020, the closing stock price of our common stock has ranged from a low of $52.17 to a high of $151.18, and the closing sale price of our common stock on February 25, 2021 was $190.51 per share. Fluctuations in the trading price or liquidity of our 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 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;

•issuances of equity or equity-linked securities by us; 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.

-28-

Our NOL Protective Amendment could adversely impact the value and trading liquidity of our common stock.

On May 4, 2010, our stockholders approved an amendment (the “NOL Protective Amendment”) to our Certificate of Incorporation. The NOL Protective Amendment places restrictions on the transfer of our common stock that could adversely affect our ability to use our domestic Federal Net Operating Loss carryforward (“NOL”). In particular, the NOL Protective 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 NOL Protective Amendment (a “Transfer Violation”) shall be void ab initio under the 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 NOL Protective 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 NOL Protective 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 NOL Protective 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 NOL Protective 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). On August 7, 2019, our board of directors determined to waive the application of any NOL transfer restrictions contained in our Certificate of Incorporation with respect to the issuance and transfer of our Notes, any issuance of shares of the Company’s common stock upon conversion of any of the Notes, and any subsequent and further transfer of any such common stock, to the extent such restrictions would otherwise have been applicable thereto. In January 2020, our board of directors waived the application of any NOL transfer restrictions contained in our Certificate of Incorporation with respect to the issuance and sale of the shares of preferred stock and underlying common stock issued in connection with the financing of the scil acquisition. These waivers, 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. State net operating loss carryforwards may be similarly or more stringently limited. Any limitations on our ability to use our pre-change of ownership net operating losses to offset taxable income could potentially result in increased future tax liability to us.

If securities analysts do not publish research or reports about our business, or if they downgrade our stock, the price of our stock could decline.

The trading market for our common stock will likely be influenced by research and reports that securities or industry analysts publish about us or our business. In the event securities or industry analysts cover our company and one or more of these analysts downgrades our stock, lowers their price target, or publishes

-29-

unfavorable or inaccurate research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.

We have not declared or paid any dividends on our common stock since 2012 and we do not anticipate paying any cash dividends in the foreseeable future.

We have not declared or paid any dividends on our common stock since October 2012. We intend to retain any earnings to finance the operation and expansion of our business, and we do not anticipate paying any cash dividends in the future. As a result, investors in our common stock may only receive a return on their investment in our common stock if the market price of our common stock increases.

We have fewer 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 common stock on The Nasdaq Capital Market. We may also be unable to otherwise maintain our listing on The Nasdaq Capital Market.

We have fewer 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 were delisted from The Nasdaq Capital Market, our 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 common stock, which could severely limit market liquidity of the 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.

Provisions in our Certificate of Incorporation and bylaws and under Delaware law might discourage, delay or prevent a change of control of our company or changes in our management and, therefore, depress the trading price of our common stock.

Our Certificate of Incorporation and bylaws contain provisions that could depress the trading price of our common stock by acting to discourage, delay or prevent a change of control of our company or changes in our management that the stockholders of our company may deem advantageous. These provisions:

•place restrictions on the transfer of our common stock that could adversely affect our ability to use our domestic NOL, which can have an effect of preventing a takeover;

•provide that our board of directors may, without stockholder approval, issue shares of preferred stock with special voting or economic rights;

•prohibit stockholders from calling a special meeting of our stockholders;

•provide that the board of directors is expressly authorized to make, alter or repeal our bylaws; and

-30-

•establish advance notice requirements for nominations for elections to our board of directors or for proposing matters that can be acted upon by stockholders at stockholder meetings.

Additionally, we are subject to Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested” stockholder for a period of three years following the date on which the stockholder became an “interested’ stockholder and which may discourage, delay, or prevent a change of control of our company.

Any provision of our Certificate of Incorporation, bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also negatively affect the price that some investors are willing to pay for our common stock.

Risks related to the outstanding Notes

Servicing our debt will require a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial debt.

Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including the amounts payable under the Notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.

We may not have the ability to raise the funds necessary to settle conversions of the Notes in cash or to repurchase the Notes upon a fundamental change, and our future debt may contain, limitations on our ability to pay cash upon conversion or repurchase of the Notes.

Holders of the Notes will have the right to require us to repurchase their notes upon the occurrence of a fundamental change at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any. In addition, upon conversion of the Notes, unless we elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the Notes being converted. However, we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of Notes surrendered therefor or Notes being converted. In addition, our ability to repurchase the Notes or to pay cash upon conversions of the Notes may be limited by law, by regulatory authority or by agreements governing our existing and future indebtedness. Our failure to repurchase Notes at a time when the repurchase is required by the indenture or to pay any cash payable on future conversions of the Notes as required by the indenture would constitute a default under the indenture. If a fundamental change occurs, or if the Notes are accelerated due to an event of default under the indenture, such events may lead to a default under agreements governing our future indebtedness. Any future indebtedness of ours may contain restrictions on our ability to pay cash upon conversion or repurchase of the Notes. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the Notes or make cash payments upon conversions thereof.

-31-

The conditional conversion feature of the Notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional conversion feature of the Notes is triggered, holders of Notes will be entitled to convert the Notes at any time during specified periods at their option. If one or more holders elect to convert their Notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share) or by electing an exchange process for the Notes and a designated financial institution delivers the applicable conversion consideration, we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders of Notes do not elect to convert their Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the Notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.

Overview

We sell advanced veterinary diagnostic and specialty products. Our offerings include Point of Care laboratory instruments and consumables; Point of Care digital imaging diagnostic instruments; digital cytology 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.

Point of Care laboratory instruments and other sales include outright instrument sales, revenue recognized from sales-type lease treatment, and other revenue sources, such as charges for repairs. Revenue from Point of Care laboratory consumables 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. Instruments placed under subscription agreements are considered operating or sales-type

leases, depending on the duration and other factors of the underlying agreement. A loss of, or disruption in, the 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 consumables 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 consumable.

Radiography is the largest product offering in Point of Care imaging, which includes digital and computed radiography and ultrasound instruments. Radiography solutions typically consist of a combination of hardware and software placed with a customer, often combined with an ongoing service and support contract. 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 diagnostic laboratory placements discussed above where ongoing consumable revenue is often a larger component of economic value as a given instrument is used.

-35-

Pharmaceuticals, Vaccines and Diagnostic ("PVD") revenue, includes single use diagnostic and other tests, pharmaceuticals and biologicals as well as research and development, licensing and royalty revenue. 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.

Other Vaccines and Pharmaceuticals ("OVP") revenue is generated in our USDA, FDA and DEA 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 of our U.S. inventory, excluding our imaging products, is stored at this facility and related fulfillment logistics are managed there. Our OVP revenue includes vaccines and pharmaceuticals produced for third parties. OVP is attributable only to the North America segment.

All of our products are ultimately sold primarily to or through veterinarians. In many cases, veterinarians will mark up their costs to their customers. The acceptance of our products by veterinarians is critical to our success. These products are sold directly to end users by us as well as through distribution relationships, such as the sale of kits to conduct blood testing to third-party veterinary diagnostic laboratories and sales to independent third-party distributors. Revenue from direct sales and distribution relationships represented 72% and 28%, respectively, of revenue for the year ended December 31, 2020 compared to 64% and 36%, respectively, for the year ended December 31, 2019.

Segment Change

During the second quarter of 2020, following the scil acquisition, the chief operating decision maker (“CODM”) changed how he assesses performance and allocates resources based on geographic regions. As a result, the Company determined it has two operating and reportable segments: North America and International. North America consists of the United States, Canada and Mexico. International consists of geographies outside of North America, primarily our operations in Australia, France, Germany, Italy, Malaysia, Spain and Switzerland. The Company's core strategic focus on point of care laboratory and imaging products is included in both segments. The North America segment also includes the contract manufacturing

of vaccines and pharmaceutical products. The Company revised prior comparative periods to conform to the current period segment presentation. Refer to Note 18 - Segment Reporting to the consolidated financial statements included in Part II. Item 8 of this Annual Report on Form 10-K for further information.

Impact of COVID-19 Pandemic and Current Economic Environment

Beginning in the first quarter of 2020, to limit the spread of COVID-19, governments took various actions including the issuance of stay-at-home policies and social distancing procedures and guidelines, causing some businesses to adjust, reduce or suspend business and operating activities. Veterinary care is widely recognized as an "essential" service for pet owners, and veterinarians continued to deliver essential medical care for sick and injured pets. The stay-at-home policies deployed early in 2020 to combat the spread of COVID-19 resulted in a decrease in companion animal clinical visits, including delay of elective procedures and wellness visits and as a result lower demand for diagnostic testing services. During the second and third quarters of 2020, certain local, state and federal governments began to ease the stay-at-home policies and allowed more businesses and facilities to re-open, leading to a recovery in companion animal clinical visits and associated demand for our diagnostic products. Finally, during the fourth quarter, increased restrictions, mainly in the European Union, certain parts of Canada and Australia, in which we operate, re-emerged. The extent to which

-36-

the continuation, or another wave outbreak of COVID-19, or an outbreak of other health epidemics could impact our business, results of operations and financial condition, including the potential for write-offs or impairments of assets and suspension of capital investments, will depend on future developments. We are unable to predict with certainty the effects of the COVID-19 pandemic on our customers, suppliers and vendors, as well as the actions of governments, and when and to what extent normal economic and operating conditions can resume; these effects may differ from those assumed in our projected estimates. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts, mainly in our ability to place new capital equipment, to our business as a result of any economic impact that has occurred or may occur in the future.

As a result of social distancing measures, on-site installations of POC Lab and Imaging equipment continue to experience intermittent delays. While not significant to the overall results of the of the year, on-site installations of equipment have been impacted since March. However, our financial position remains strong. On April 1, 2020, we closed our acquisition of scil; the transaction was fully financed by a preferred stock offering. We have sufficient liquidity to sustain our operations and do not anticipate a need to access additional capital outside of the various programs available to our overseas subsidiaries.

While we have experienced some intermittent delays in receiving supply and a slight increase in shipping costs, our supply chain has not been significantly impacted. Our major research and development projects are continuing to progress substantially as planned but we have experienced sporadic delays in receiving validation samples and device components as well as inefficiencies in remote collaboration and field-testing.

We do not know how long COVID-19 related challenges will continue. The ultimate impact on our business will depend on many factors substantially beyond our control and difficult to predict. In the near-term and with asynchronous variation across geographies, we anticipate veterinary hospitals may temporarily delay capital equipment investments as a result of heightened conservatism and the effects of social distancing on in-clinic demonstrations and installations. Despite these headwinds, we believe we are well positioned because: (1) our customers and products are essential, (2) our main Point of Care laboratory business continues to show healthy consumables use and margin, (3) our subscriptions model metrics continue to show solid performance, (4) our vaccines and pharmaceuticals business continues to perform with minimal disruption, (5) our balance sheet is strong, and (6) our employees, logistics, supply chain, and operations continue to operate well in the current environment and they are fully prepared for both a phased return and an instant return to full capacity.

Critical Accounting Estimates

Note 1 - Summary of Significant Accounting Policies to the consolidated financial statements included in Part II. Item 8 of this Annual Report on Form 10-K describes the significant accounting policies used in preparation of these consolidated financial statements. We believe the following critical accounting estimates and assumptions may have a material impact on reported financial condition and operating performance and involve significant levels of judgment to account for highly uncertain matters or are susceptible to significant change. In each of these areas, management makes estimates based on historical results, current trends and future projections.

-37-

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, 2020 and 2019, we had valuation allowances of approximately $6.4 million and $5.7 million, respectively.     

Business Combinations

We account for transactions that represent business combinations under the acquisition method of accounting, which requires us to allocate the total consideration paid for each acquisition to the assets we acquire and liabilities we assume based on their fair values as of the date of acquisition, including identifiable intangible assets. The allocation of the purchase price utilizes significant estimates in determining the fair values of identifiable assets acquired and liabilities assumed, especially with respect to intangible assets. We may refine our estimates and make adjustments to the assets acquired and liabilities assumed over a measurement period, not to exceed one year. 

Valuation of Goodwill and Intangibles

A significant portion of the purchase price for acquired businesses is generally assigned to intangible assets. Intangible assets other than goodwill are initially valued at fair value. If a quoted price in an active market for the identical asset is not readily available at the measurement date, the fair value of the intangible asset is estimated based on discounted cash flows using market participant assumptions, which are assumptions that are not specific to Heska. The selection of appropriate valuation methodologies and the estimation of discounted cash flows require significant assumptions about the timing and amounts of future cash flows, risks, appropriate discount rates, and the useful lives of intangible assets. When material, we utilize independent valuation experts to advise and assist us in determining the fair values of the identified intangible assets acquired in connection with a business acquisition and in determining appropriate amortization methods and periods for those intangible assets. Goodwill is initially valued based on the excess of the purchase price of a business combination over the fair value of acquired net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized.

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 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.

-38-

As part of our goodwill testing process, we evaluate factors specific to a reporting unit as well as industry and macroeconomic factors that are reasonably likely to have a material impact on the fair value of a reporting unit. Examples of the factors considered in assessing the fair value of a reporting unit include: the results of the most recent impairment test, the competitive environment, the regulatory environment, anticipated changes in product or labor costs, revenue growth trends, the consistency of operating margins and cash flows and current and long-range financial forecasts. The long-range financial forecasts of the reporting units, which are based upon management’s long-term view of our markets, are used by senior management and the Board of Directors to evaluate operating performance.

We performed qualitative assessments in the fourth quarters of 2020, 2019 and 2018 and determined that no indications of impairment existed.

We assess the realizability of intangible assets other than goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If an impairment review is triggered, we evaluate the carrying value of intangible assets based on estimated undiscounted future cash flows over the remaining useful life of the primary asset of the asset group and compare that value to the carrying value of the asset group. The cash flows that are used contain our best estimates, using appropriate and customary assumptions and projections at the time. If the net carrying value of an intangible asset exceeds the related estimated undiscounted future cash flows, an impairment to adjust the intangible asset to its fair value would be reported as a non-cash charge to earnings. If necessary, we would calculate the fair value of an intangible asset using the present value of the estimated future cash flows to be generated by the intangible asset, and applying a risk-adjusted discount rate. We had no impairments of our intangible assets during the years ended December 31, 2020, 2019 and 2018.

These valuations require the use of management’s assumptions, which would not reflect unanticipated events and circumstances that may occur.

Share-Based Compensation Expense

We utilize share-based compensation arrangements as part of our long-term incentive plan. Our share-based compensation programs provide for grants of many types of awards, but we currently grant stock options, including performance stock options, and restricted stock awards, along with the issuance of employee stock purchase rights. The total fair value of future awards may vary significantly from past awards based on a number of factors, including our share-based award practices. Therefore, share-based compensation expense is likely to fluctuate, possibly significantly, from year to year.

The majority of our currently issued restricted stock awards and performance stock options are tied to Company and market-related performance metrics and generally include a time vesting component. We also grant stock options and restricted stock awards tied to time vesting to employees and directors. All significant inputs into the determination of expense as well as the related expense are discussed further in Note 12 - Capital Stock to the consolidated financial statements included in Part II. Item 8 of this Annual Report on Form 10-K.

Restricted Stock Awards (Time Vesting)

The fair value of restricted stock awards with only time-based vesting terms used in our expense recognition method is measured based on the number of shares granted and the closing market price of our common stock on the date of grant. Such value is recognized as an expense over the corresponding requisite service period. Forfeitures are accounted for as they occur.

-39-

Performance-Based Stock Compensation Awards

We also grant restricted stock awards and performance stock options subject to performance vesting criteria, in addition to service, to our executive officers and other key employees. This type of grant consists of the right to receive shares of, or options to purchase, common stock, subject to achievement of time-based criteria and certain Company and market performance-related goals over a specified period, as established by the Compensation Committee of our Board of Directors. We recognize any related share-based compensation expense ratably over the requisite service period based on the probability assessment on the outcome of the performance condition related to company performance metrics. The fair value used in our expense recognition method is measured based on the number of shares granted and the closing market price of our common stock on the date of grant for restricted stock awards and the Black-Scholes model for performance stock options. The amount of share-based compensation expense recognized in any one period can vary based on the attainment or expected attainment of the performance goals. If such performance goals are not ultimately met, no compensation expense is recognized and any previously recognized compensation expense is reversed. We recognize any related share-based compensation expense ratably over the service period based on the most probable outcome of the performance condition related to market performance metrics. For awards related to market performance, the fair value used in our expense recognition method is measured based on the number of shares granted, and a Monte Carlo simulation model, which incorporates the probability of the achievement of the market-related performance goals as part of the grant date fair value. If such performance goals are not ultimately met, the expense is not reversed.

Recent Accounting Pronouncements

From time to time, the FASB or other standard setting bodies issue new accounting pronouncements. Updates to the FASB ASC are communicated through issuance of an ASU. Unless otherwise discussed, we believe that 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 the consolidated financial statements included in Part II. Item 8 of this Annual Report on Form 10-K.

Revenue

Total revenue increased 61% to $197.3 million in 2020 compared to $122.7 million in 2019. The significant increase in revenue is driven mainly by the acquisitions of CVM and scil, which represented an increase of $68.2 million of revenue for the twelve months ended December 31, 2020, which was not included in the

-41-

prior year period. The remaining increase is a result of sales of POC Lab Consumables, contract manufactured product for third parties, including TriHeart, and immunotherapy products.

Gross Profit

Gross profit increased 49.3% to $81.3 million in 2020 compared to $54.4 million in 2019.  Gross margin percent declined to 41.2% in 2020 compared to 44.4% in 2019. The increase in gross profit is due to recent acquisitions of CVM and scil, which represented an increase of $21.3 million increase in gross profit in the twelve months ended December 31, 2020, which was not included in the prior year period. Remaining increase in gross profit is due to increased sales of higher margin products such as POC Lab Consumables and contract manufacturing production increases. The decrease in gross margin percentage is due to lower margin in our newly acquired businesses.

Operating Expenses

Selling and marketing expenses increased 39% to $38.5 million in 2020 compared to $27.7 million in 2019. The increase is a direct result of international expansion related to recent acquisitions and is in line with management expectations.

Research and development expenses increased 6% to $8.8 million in 2020, compared to $8.2 million in 2019. The increase was primarily driven by spending on product development for a urine and fecal diagnostic analyzer and enhanced immunodiagnostic offerings. As we invest in future growth of the Company, the increased research and development expenses is consistent with the spending initiatives of management.

General and administrative expenses increased 132% to $42.2 million in 2020, compared to $18.2 million in 2019. The increase is driven primarily by additional expenses related to the impact of international acquisitions compared to the prior year of $11.4 million, as well as one-time costs primarily related to the acquisition of scil, which were $9.5 million in 2020 compared to $1.0 million in 2019. In addition, stock-based and other compensation expenses increased by $4.5 million.

Interest and Other (Income) Expense, Net

Interest and other expense, net, was $5.6 million in 2020, compared to $2.9 million in 2019. The increase was primarily driven by interest expense as a result of the Notes. Refer to Note 16 - Convertible Notes and Credit Facility to the consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K.

Income Tax (Benefit) Expense

In 2020, we had total income tax expense of $0.2 million compared to a total income tax benefit in 2019 of $1.4 million. See Note 5 - Income Taxes to the consolidated financial statements included in Part II. Item 8 of this Annual Report on Form 10-K for additional information regarding our income taxes.

Net (Loss) Income Attributable to Heska Corporation

Net loss attributable to Heska Corporation was $14.4 million in 2020, compared to net loss attributable to Heska Corporation of $1.5 million in 2019. The difference between this line item and "Net (loss) income after equity in losses of unconsolidated affiliates" is the net income or loss attributable to the minority interest in our French subsidiary, Optomed, which we purchased in February 2019. The difference between these line items was a gain of $0.4 million for 2020, and a gain of $0.3 million for 2019. In October 2020, the Company acquired the remaining 30% minority interest in Optomed.

Adjusted EBITDA

Adjusted EBITDA in the twelve months ended December 31, 2020 was $22.3 million (11.3% adjusted EBITDA margin), compared to $10.4 million (8.5% adjusted EBITDA margin) in the twelve months ended December 31, 2019. The increase is driven by increased revenue and gross profit as discussed above. The increases in operating expenses are excluded from adjusted EBITDA. See “Non-GAAP Financial Measures” for a reconciliation of adjusted EBITDA to net income and adjusted EBITDA margin to net loss margin, the closest comparable GAAP measures, for each of the periods presented.

Earnings Per Share

Loss per share attributable to Heska was $1.66 per diluted share in the twelve months ended December 31, 2020 compared to loss of $0.20 per diluted share in the twelve months ended December 31, 2019. The decline is primarily due to increases in operating expenses as discussed above, interest and amortization charges relating to the Notes, and increased deferred income tax expense.

Non-GAAP Earnings Per Share

Non-GAAP EPS was income of $0.74 per diluted share in the twelve months ended December 31, 2020 compared to income of $0.49 per diluted share in the twelve months ended December 31, 2019. The decline is primarily due to cash interest related to the Notes and increased deferred income taxes. See “Non-GAAP Financial Measures" for a reconciliation of non-GAAP EPS to net (loss) income attributable to Heska per diluted share, the closest comparable U.S. GAAP measure, in each of the periods presented.

Non-GAAP Financial Measures

In addition to financial measures presented on the basis of accounting principles generally accepted in the U.S. (“U.S. GAAP”), we also present EBITDA, adjusted EBITDA, adjusted EBITDA margin, and non-GAAP net income (loss) per diluted share, which are non-GAAP measures.

These measures should be viewed as a supplement to, not substitute for, our results of operations presented under U.S. GAAP. The non-GAAP financial measures presented may not be comparable to similarly titled measures of other companies because they may not calculate their measures in the same manner. Management uses EBITDA, adjusted EBITDA, adjusted EBITDA margin and non-GAAP net income (loss) per diluted share as key profitability measures, which are included in our quarterly analyses of our operating results to our senior management team, our annual budget and related goal setting and other performance measurements. We believe these non-GAAP measures enhance our investors' understanding of our business performance and that not adjusting for the items included in the reconciliations below would hinder comparison of the performance of our businesses on a period-over-period basis or with other businesses.

Analysis by Segment

The North America segment includes sales and costs from the United States, Canada and Mexico. The International segment includes sales and costs from Australia, France, Germany, Italy, Malaysia, Spain and Switzerland.

The North America segment represented 66.4% of our revenue for the twelve months ended December 31, 2020, and the International segment represented 33.6% of our revenue for the twelve months ended December 31, 2020.

The following sections and tables set forth, for the periods indicated, certain data derived from our Consolidated Statements of (Loss) Income (in thousands).

North America Segment

	Twelve Months Ended December 31,						Change

North America Operating (Loss) Income Margin	(3.8)		%	1.2		%

North America segment revenue increased 13.6% to $131.1 million for the twelve months ended December 31, 2020, compared to $115.4 million for the twelve months ended December 31, 2019. The $15.6 million increase was driven by a $8.4 million in Tri-Heart sales, an 11.2% increase in POC Lab Consumables, and a $1.6 million increase related to OVP. These increases were partially offset by a 4.6% decrease in sales from Point of Care Imaging, which was largely expected as a result of the government restrictions in place relating to COVID-19.

-45-

Gross profit was $60.9 million compared to $52.3 million for the twelve months ended December 31, 2020 and 2019, respectively. The increase in gross profit for both periods is primarily driven by increased revenue in the current year, specifically related to PVD and POC Lab Consumables. Gross margin was 46.5% for the twelve months ended December 31, 2020, compared to 45.3% in the twelve months ended December 31, 2019. The increase is due to increased revenue and margins for consumables, Tri-Heart and OVP, which had reduced production in the twelve months ended December 31, 2019.

North America operating loss increased $6.4 million to $5.0 million in the twelve months ended December 31, 2020 from income of $1.4 million for the twelve months ended December 31, 2019. While we experienced increased revenue and gross margin in 2020, the increase in operating loss is driven by one-time transaction related costs primarily relating to the acquisition of scil and increased stock-based and other compensation expenses in 2020.

International Segment

	Twelve Months Ended December 31,						Change
	2020			2019			Dollar Change		% Change
Point of Care laboratory:	$	40,136		$	419		$	39,717	9,479.0	%

Point of Care imaging	22,537			3,998			18,539		463.7	%
PVD	3,584			2,821			763		27.0	%
Total International revenue	$	66,257		$	7,238		$	59,019	815.4	%
International Gross Profit	$	20,387		$	2,115		$	18,272	863.9	%
International Gross Margin	30.8		%	29.2		%
International Operating (Loss)	$	(3,215)		$	(1,099)		$	(2,116)	(192.5)	%
International Operating (Loss) Margin	(4.9)		%	(15.2)		%

International revenue was $66.3 million compared to $7.2 million for the twelve months ended December 31, 2020 and 2019, respectively. The increase is due to the acquisitions of CVM and scil, which contributed approximately $57.8 million of revenue in the twelve months ended December 31, 2020, that was not included in the comparable period.

Gross profit was $20.4 million compared to $2.1 million for the twelve months ended December 31, 2020 and 2019, respectively. Gross margin for the International segment was 30.8% for the year ended December 31, 2020, compared to 29.2% for the year ended December 31, 2019. The increase in gross profit and gross margin is driven by increased revenue from the acquisitions of CVM and scil, which contributed approximately $18.1 million of gross profit that was not included in the comparable period.

International operating loss increased $2.1 million for the year ended December 31, 2020, compared to the prior year. The increase in operating loss in is driven by increased depreciation and amortization and one-time transaction related costs in the current year; partially offset by increased International revenue and gross profit discussed above.

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 may be beyond our control. Our primary source of liquidity is our available cash of $86.3 million, which includes net proceeds from the issuance of the Notes and cash generated from current operations. In January 2020, the Company transferred $14.6 million of consideration for the purchase of the CVM companies. Refer to Note 3 - Acquisitions and Related Party Items to the consolidated financial statements included in Item II. Part 8 of this Annual Report on Form 10-K. Additionally, we financed the acquisition of scil through a private placement of convertible preferred equity from which we raised $122 million, while we transferred approximately $110 million in purchase price, netting a remaining $11 million of liquidity. Refer to Note 12 - Capital Stock to the consolidated financial statements included in Item II. Part 8 of this Annual Report on Form 10-K.

For the year ended December 31, 2020, we had a net loss after equity in losses of unconsolidated affiliates of $14.8 million and net cash used by operations of $0.7 million. At December 31, 2020, we had $86.3 million of cash and cash equivalents and working capital of $129.2 million. A discussion of significant changes from the periods ending December 31, 2019 compared to December 31, 2018 can be found in Part II. Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2019.

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

	Year Ended December 31,
	2020		2019
Net cash (used in) provided by operating activities	$	(656)	$	3,296
Net cash used in investing activities	(126,597)		(1,923)
Net cash provided by financing activities	123,764		74,264
Effect of currency translation on cash	793		4
Increase (decrease) in cash and cash equivalents	(2,696)		75,641
Cash and cash equivalents, beginning of the period	89,030		13,389
Cash and cash equivalents, end of the period	$	86,334	$	89,030

Net cash used by operating activities was $0.7 million in 2020, compared to net cash provided by operating activities of $3.3 million in 2019, a decrease of approximately $4.0 million. The decrease in cash from operating activities is primarily due to the $13.0 million decrease in net income after equity in losses of unconsolidated affiliates for the twelve months ended December 31, 2020 compared to the twelve months ended December 31, 2019. Net cash also decreased due to significant working capital fluctuations such as a $9.4 million decrease in cash from accounts receivable driven primarily by increased sales, and a $6.3 million decrease in cash provided by inventories, due to the timing of purchases and sales. These decreases are partially offset by an increase cash from the aggregate of accounts payable and other liabilities of $8.4 million (driven by a settlement payment and related legal fees in 2019) and an increase in cash from other assets of $3.3 million. In addition, the net cash used by operating activities is offset by non-cash transactions, including a $6.5 million increase in depreciation and amortization driven by the acquisition of scil, a $4.5 million increase in stock-based compensation expense, and a $1.2 million increase related to amortization of the debt discount.

Net cash used in investing activities was $126.6 million in 2020, compared to net cash used in investing activities of $1.9 million in 2019, an increase of approximately $124.7 million. The increase in cash used

-47-

for investing activities was driven by a $104.4 million investment for the scil acquisition, net of cash acquired, a $14.4 million payment of consideration for the December 2019 acquisition of CVM, and a $6.7 million convertible note receivable.

Net cash provided by financing activities was $123.8 million in 2020, compared to net cash provided by financing activities of $74.3 million in 2019, an increase of approximately $49.5 million. The change was driven primarily by the issuance of preferred stock resulting in $122.0 million in proceeds, primarily used for financing the acquisition of scil, while our Notes financing in 2019 generated net proceeds of $77.1 million, which is net of debt issuance and the repayment of a pre-existing credit facility, resulting in a financing change year over year of $44.9 million. Additionally, net proceeds from issuance of common stock yielded $4.4 million more in 2020 as compared to 2019.

We believe that our cash, cash equivalents and marketable securities balances, as well as the cash flows generated by our operations, will be sufficient to satisfy our anticipated cash needs for working capital and capital expenditures, including selling and marketing team expansion and product development initiatives, for at least the next 12 months. Our belief may prove to be incorrect, however, and we could utilize our available financial resources sooner the we currently expect. For example, we are actively seeking acquisitions that are consistent with our strategic direction, which may require additional capital. Our future capital requirements and the adequacy of available funds will depend on many factors, including those set forth in Part I, Item 1A, "Risk Factors", of this Form 10-K. We may be required to seek additional equity or debt financing in order to meet these future capital requirements, even in the absence of any acquisitions. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us, or at all. If we are unable to raise additional capital when desired, our business, results of operations and financial condition would be adversely affected.

Effect of currency translation on cash

Net effect of foreign currency translations on cash changed $789 thousand to a $793 thousand positive impact in 2020, compared to a $4 thousand positive impact in 2019. The net effect of foreign currency translation on cash changed $14 thousand to a $4 thousand positive impact in 2019 from a $10 thousand negative impact in 2018. These effects are related to changes in exchange rates between the U.S. Dollar and the Swiss Franc, Euro, Canadian Dollar, Australian Dollar, and Malaysian Ringgit which are the functional currencies of our subsidiaries.

Material Cash Requirements

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 research and development 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.

-48-

The following table presents certain future payments due by the Company as of December 31, 2020 (in thousands):

	Total		Less Than 1 Year		1 - 3 Years		3 - 5 Years		After 5 Years
Purchase obligations	$	24,991	$	10,053	$	10,551	$	4,387	$	—
Operating lease obligations	6,355		2,158		3,783		282		132
Finance lease obligations	574		294		198		64		18
Other long term borrowings	554		—		222		222		110
Convertible senior notes (1)	86,250		—		—		—		86,250
Future interest obligations (2)	18,492		3,235		6,484		6,480		2,293
Total	$	137,216	$	15,740	$	21,238	$	11,435	$	88,803

(1) Includes the principal amount of the convertible senior notes. Although the notes mature in 2026, they can be converted into cash and shares of our common stock prior to maturity if certain conditions are met. Any conversion prior to maturity can result in repayments of the principal amounts sooner than the scheduled repayments as indicated in the table. For additional information, refer to Note 16 - Convertible Notes and Credit Facility to the consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K.

(2) Includes interest payments for both the convertible senior notes and other long term borrowings.

Net Operating Loss Carryforwards

As of December 31, 2020, we had a net operating loss carryforward (“NOL”) and domestic research and development tax credit carryforward. See Note 5 - Income Taxes to the consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K for additional information regarding our carryforwards.

-49-

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 U.S. and foreign interest rates and changes in foreign currency exchange rates as measured against the U.S. Dollar. These exposures are directly related to our normal operating and funding activities.

Interest Rate Risk

In September 2019, we issued $86.25 million aggregate principal amount of Notes. The fair market value of the Notes is affected by our common stock price. The fair value of the Notes will generally increase as our common stock price increases and will generally decrease as our common stock price declines in value. In addition, the fair market value of the Notes is exposed to interest rate risk. Generally, the fair market value of our fixed interest rate Notes will increase as interest rates fall and decrease as interest rates rise. Additionally, on our balance sheet we carry the Notes at face value less unamortized discount and debt issuance cost and we present the fair value for required disclosure purposes only. For additional information, refer to Note 16 - Convertible Notes and Credit Facility to the consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K and to our consolidated financial statements included herein. We had no interest rate hedge transactions in place on December 31, 2020.

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, 2020. We do not currently consider foreign currency risk to be material to our business.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders

Heska Corporation

Opinion on the financial statements

We have audited the accompanying consolidated balance sheet of Heska Corporation and subsidiaries (the “Company”) as of December 31, 2020, the related consolidated statements of loss, comprehensive loss, stockholders’ equity, and cash flows for the year ended December 31, 2020, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and the results of its operations and its cash flows for the year ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”), and our report dated February 26, 2021 expressed an unqualified opinion.

Basis for opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits 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. We believe that our audits provide a reasonable basis for our opinion.

Critical audit matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Stock-based compensation - assessment of probability related to stock-based compensation subject to performance based vesting requirements

As described further in Note 12 to the financial statements, the Company granted restricted stock awards and stock options. Certain of the restricted stock awards and stock options have performance based vesting periods, which vest based on when performance targets are met. Performance based awards are recognized as

-52-

an expense based on the probability of achieving the underlying performance targets. We identified the probability assessment of achieving the performance targets as a critical audit matter.

The principal consideration for our determination that the probability of achieving the performance targets is a critical audit matter is that the probability is based on a subjective assessment of the Company’s prospective financial information. The probability assessment requires management to estimate the successful development and market acceptance of future product introductions, future sales targets, operating performance, and EBITDA. Changes in the subjective probability assessment can materially affect the amount and timing of the recognition of stock-based compensation expense and require significant auditor subjectivity in evaluating the reasonableness of those judgments and estimates.

Our audit procedures related to the probability of achieving the performance targets included the following, among others.

–We tested the design and operating effectiveness of internal controls relating to management’s determination of stock-based compensation expense, including testing management’s review controls over the identification of the terms of the performance conditions and the key inputs used in determining the probability of achieving the performance targets.

–We evaluated the reasonableness of management’s prospective financial information by comparing management’s previous forecasts to actual results to assess management’s ability to accurately forecast actual results. We also evaluated the reasonableness of forecasted revenue by comparing sales growth to current market and industry trends; operating performance and EBITDA by comparing to current market and industry trends, historical information, and inquiring of individuals outside of the finance department; and future product introductions by evaluating the status of development, recent placement history, and inquiring of individuals outside of the finance department. We also evaluated the consistency of forecasts used in the probability assessment with other elements of the financial statements that use the forecast as an input.

Business combination of scil animal care company GmbH

As described further in Note 3 to the financial statements, the Company completed the acquisition of scil animal care company GmbH (“scil”) on April 1, 2020. The Company paid approximately $110.3 million in cash to acquire 100% of the capital stock of scil, which resulted in the identification and recognition of $44.5 million of other intangible assets. We identified the Company’s determination of the fair value of customer relationships and the trademarks and trade names not subject to amortization (“trade name”) intangible assets acquired as a critical audit matter.

The principal considerations for our determination that the Company’s valuation of the customer relationships and the trade name intangible assets acquired is a critical audit matter due to the high degree of management subjectivity in the related fair value estimates. This requires management to evaluate historical results and expectations of future operating performance based on relevant information available to them regarding expectations of industry performance, as well as, expectations for company-specific performance. Significant assumptions (assumed revenue growth rates, discount rates, and operating margin) utilized to determine the fair value are subject to estimation uncertainty and require significant auditor subjectivity in evaluating the reasonableness of those judgments and estimates.

Our audit procedures related to the business combination of scil included the following, among others.

–We tested the design and operating effectiveness of internal controls relating to management’s valuation of the customer relationships and trade name intangible assets, which includes management’s review of the preliminary valuation report for reasonableness of significant assumptions used in the fair value calculations.

–We evaluated the reasonableness of management’s forecasted revenue growth rate and operating margin by comparing to current market and industry trends, historical data, and strategic business plans. We performed a sensitivity analysis on the assumed revenue growth rate and operating margin assumptions. We utilized a valuation specialist to assist in evaluating the appropriateness of the Company’s selection of valuation methodology and evaluating the reasonableness of the discount rate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders

Heska Corporation

Opinion on internal control over financial reporting

We have audited the internal control over financial reporting of Heska Corporation and subsidiaries (the “Company”) as of December 31, 2020, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in the 2013 Internal Control—Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated financial statements of the Company as of and for the year ended December 31, 2020, and our report dated February 26, 2021 expressed an unqualified opinion on those financial statements.

Basis for opinion

The Company’s management is responsible 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 (“Management’s Report”). Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Our audit of, and opinion on, the Company’s internal control over financial reporting does not include the internal control over financial reporting of scil animal care company GmbH, a wholly-owned subsidiary, whose financial statements reflect total assets and revenues constituting 45% and 30% , respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2020. As indicated in Management’s Report, scil animal care company GmbH was acquired during 2020. Management’s assertion on the effectiveness of the Company’s internal control over financial reporting excluded internal control over financial reporting of scil animal care company GmbH.

Definition and limitations of internal control over financial reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized

-55-

acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of Heska Corporation

Opinion on the Financial Statements

We have audited the accompanying balance sheet of Heska Corporation and subsidiaries (the “Company”) as of December 31, 2019, and the related statements of income, comprehensive income, stockholders' equity, and cash flows for the years ended December 31, 2019 and 2018, and the related notes (collectively referred to as the “financial statements”).

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, 2019 and the results of its operations and its cash flows for the years ended December 31, 2019 and 2018, in conformity with accounting principles generally accepted in the United States of America.

Change in Accounting Principle

As discussed in Note 1 to the financial statements, the Company adopted the Accounting Standards Codification (ASC) Topic 842, “Leases,” using the modified retrospective adoption method on January 1, 2019.

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 U.S. 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. 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.

HESKA CORPORATION AND SUBSIDIARIES

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 diagnostic laboratory instruments and supplies; digital imaging diagnostic products, software and services; digital cytology 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

In the opinion of management, the accompanying Consolidated Financial Statements contain all adjustments, consisting of normal, recurring adjustments, necessary to present fairly the financial position of the Company as of December 31, 2020 and 2019, as well as the results of our operations, statements of stockholders' equity and cash flows for the twelve months ended December 31, 2020, 2019 and 2018.

The audited Consolidated Financial Statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Our audited 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 loss attributable to non-controlling interest" on our Consolidated Statements of (Loss) Income. Our audited Consolidated Financial Statements are stated in U.S. Dollars and have been prepared in accordance with accounting principles generally accepted in the U.S. ("GAAP").

Beginning in the first quarter of 2020, to limit the spread of COVID-19, governments took various actions including the issuance of stay-at-home policies and social distancing procedures and guidelines, causing some businesses to adjust, reduce or suspend business and operating activities. Veterinary care is widely recognized as an "essential" service for pet owners, and veterinarians continued to deliver essential medical care for sick and injured pets. The stay-at-home policies deployed early in 2020 to combat the spread of COVID-19 resulted in a decrease in companion animal clinical visits, including delay of elective procedures and wellness visits and as a result lowers demand for diagnostic testing services. Beginning in the second quarter of 2020, certain local, state and federal governments began to ease the stay-at-home policies and allowed more businesses and facilities to re-open, leading to a recovery in companion animal clinical visits and associated demand for our diagnostic products. The extent to which the continuation, or a possible second-wave outbreak of COVID-19, or an outbreak of other health epidemics could impact our business, results of operations and financial condition, including the potential for write-offs or impairments of assets and suspension of capital investments, will depend on future developments. We are unable to predict with certainty the effects of the COVID-19 pandemic on our customers, suppliers and vendors, as well as the actions of governments, and when and to what extent normal economic and operating conditions can resume; these effects may differ from those assumed in our projected estimates. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business as a result of any economic impact that has occurred or may occur in the future.

Reclassification

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

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

Use of Estimates

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 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 net realizable value of inventory; determining future costs associated with warranties provided; 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 and investments for estimated useful lives and impairment; estimating the useful lives and standalone selling prices of instruments under leasing arrangements; determining the allocation of purchase price under purchase accounting; estimating the expense associated with the granting of stock; determining the need for, and the amount of a valuation allowance on deferred tax assets; determining the fair value of our embedded derivative; and determining the fair value of the liability component associated with the issuance of convertible debt. Our actual results may differ from these estimates and there may be changes to those estimates in future periods.

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 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.

Covetrus represented 9% and 19% of our consolidated accounts receivable at December 31, 2020 and 2019, respectively. No other customer accounted for more than 10% of our consolidated accounts receivable at December 31, 2020 or 2019.

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

Accounts Receivable and Allowance for Credit Losses

Accounts receivable are recorded net of an allowance for credit losses. From time to time, our customers are unable to meet their payment obligations. We continuously monitor our customers' credit worthiness and establish allowances for estimated credit losses related to our accounts receivable, net investment in leases, contract assets, and promissory notes. Our allowances are established based on factors surrounding the credit risk of specific customers, historical experience including collections and write-off history, and current economic conditions. Account balances are considered past due if payments have not been received within agreed upon invoice and/or contract terms and the Company may employ collection agencies and legal counsel to pursue recovery of defaulted amounts. Account balances are written off against the allowance after all collection efforts have been exhausted and it is probable the receivable will not be recovered. The Company also performs a qualitative assessment, on a quarterly basis, to monitor economic factors and other uncertainties that may require additional adjustments for the expected credit loss allowance. 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. The Company will continue to actively monitor the impact of the COVID-19 pandemic on expected credit losses. In 2020, the Company adopted Accounting

Fair Value of Financial Instruments

In accordance with ASC 820, Fair Value Measurements (“ASC 820”), the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Quoted prices in active markets for similar assets and liabilities, quoted prices for identically similar assets or liabilities in markets that are not active and models for which all significant inputs are observable either directly or indirectly.

Level 3: Unobservable inputs reflecting the reporting entity’s own assumptions or external inputs for inactive markets.

The Company's financial instruments consist of cash and cash equivalents, short-term trade receivables and payables, a long-term note receivable with an embedded derivative asset, and its 3.75% Convertible Senior Notes due 2026 (the "Notes"). 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 estimated fair value of the Notes disclosed at each reporting period is evaluated through Level 2 inputs with consideration of quoted market prices in less active markets. For additional information regarding the Company's accounting treatment for the issuance of the Notes, including the fair value measurement of the liability component, refer to Note 16. Convertible Notes.

The Company determined the redemption features of its convertible note receivable represents an embedded derivative. The estimated fair value of the embedded derivative asset is evaluated through Level 3 inputs. The carrying amount of the derivative is recorded at fair value at issuance and will be remeasured each reporting period, with the mark-to-market adjustments to be included in other expense (income). For additional information regarding the Company's accounting treatment for the convertible note receivable, including the fair value measurement of the embedded derivative, refer to Note 17. Convertible Note Receivable.

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 (Loss) 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 43 years
Machinery and equipment	2 to 10 years
Office furniture and equipment	3 to 7 years
Computer hardware and software	3 to 7 years
Leasehold and building improvements	5 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 seven 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.

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. We write down the carrying value of inventory for estimated obsolescence by an amount equal to the difference between the cost of inventory and the estimated market value when warranted based on assumptions of future demand, market conditions, remaining shelf life, or product functionality.

Investments in Unconsolidated Affiliates

Investments in unconsolidated affiliates are measured and recorded as either non-marketable equity securities or equity method investments. Non-marketable equity securities are equity securities without readily determinable fair value that are measured and recorded using a measurement alternative which measures the securities at cost minus impairment, if any, plus or minus changes from qualifying observable price changes. Equity method investments are equity securities in investees we do not control but over which we have the ability to exercise significant influence. When the equity method of accounting is determined to be appropriate, the initial measurement of the investment includes the cost of the investment and all direct transaction costs incurred to acquire the investment. Equity method investments are measured at cost minus impairment, if any, plus or minus our share of equity method investee income or loss, which is recorded as a separate line on the income statement. Both types of investments are evaluated for impairment if a triggering event occurs.

Goodwill, Intangible and Other Long-Lived Assets

Goodwill is initially valued based on the excess of the purchase price of a business combination over the fair value of acquired net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Intangible assets other than goodwill are initially valued at fair value. If a quoted price in an active market for the identical asset is not readily available at the measurement date, the fair value of the intangible asset is estimated based on discounted cash flows using market participant assumptions, which are assumptions that are not specific to the Company. The selection of appropriate valuation methodologies and the estimation of discounted cash flows require significant assumptions about the timing and amounts of future cash flows, risks, appropriate discount rates, and the useful lives of intangible assets. When material, we utilize independent valuation experts to advise and assist us in determining the fair values of the identified intangible assets acquired in connection with a business acquisition and in determining appropriate amortization methods and periods for those intangible 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 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 it is 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. Following the acquisition of scil in April 2020, we restructured our operating segments based on how the Chief Operating Decision Maker (“CODM”) manages the business, allocates resources, makes operating decisions and evaluates operating performance. As further discussed in Note 18, our new reporting segments are North America and International. As a result of the change in operating segments, we also revised our reporting units to aggregate our legal entities based on similarities in economic characteristics. Our new reporting units consist of the following: (1) Heska Corporation and Heska Canada, (2) Diamond Animal Health, (3) scil animal care company GmbH, Optomed, CVM, and Heska Australia, and (4) Heska AG.

As a result of the recent global economic disruption and uncertainty due to the COVID-19 pandemic, the

-68-

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

Company performed a qualitative assessment during the first quarter of 2020. Based on the interim assessment performed, we concluded that there was no triggering event and additionally, no indications of impairment existed. We performed qualitative assessments in the fourth quarters of 2020, 2019, and 2018 and determined that no indications of impairment existed.

We assess the realizability of intangible assets other than goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If an impairment review is triggered, we evaluate the carrying value of intangible assets based on estimated undiscounted future cash flows over the remaining useful life of the primary asset of the asset group and compare that value to the carrying value of the asset group. The cash flows that are used contain our best estimates, using appropriate and customary assumptions and projections at the time. If the net carrying value of an intangible asset exceeds the related estimated undiscounted future cash flows, an impairment to adjust the intangible asset to its fair value would be reported as a non-cash charge to earnings. If necessary, we would calculate the fair value of an intangible asset using the present value of the estimated future cash flows to be generated by the intangible asset, and applying a risk-adjusted discount rate. We had no impairments of our intangible assets during the years ended December 31, 2020, 2019, and 2018.

Revenue Recognition

We generate revenue through the sale of products, either by outright purchase by our customers or through a subscription agreement whereby our customers receive instruments and pay us a monthly fee for the consumables needed to conduct testing. Subscription placement is the majority of our Point of Care laboratory transactions while outright sales to customers are the majority of both Point of Care imaging diagnostic transactions and the sale of pharmaceuticals and vaccines.

For outright sales of products, revenue is recognized when control of the promised product or service is transferred to our customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those products or services (the transaction price). Taxes assessed by governmental authorities and collected from the customer are excluded from our revenue recognition. A performance obligation is a promise in a contract to transfer a distinct product or service to a customer and is the unit of account under ASC 606. For instruments, consumables and most software licenses sold by the Company, control transfers to the customer at a point in time. To indicate the transfer of control, the Company must have a present right to payment, legal title must have passed to the customer, the customer must have the significant risks and rewards of ownership and where acceptance is not a formality, the customer must have accepted the product or service. Heska’s principal terms of sale are FOB Shipping Point, or equivalent, and, as such, we primarily transfer control and record revenue for product sales upon shipment. If a performance obligation to the customer with respect to a sales transaction remains unfulfilled following shipment (typically owed installation), revenue recognition for that performance obligation is deferred until such commitments have been fulfilled. For extended warranty and service plans, control transfers to the customer over the term of the arrangement and as such the revenue is recognized ratably based upon the period of time elapsed under the arrangement.

Our revenue under subscription agreements relates to operating-type lease ("OTL") arrangements or sales-type lease ("STL") arrangements. Determination of an OTL or STL is primarily determined as a result of the length of the contract as compared to the estimated useful life of the instrument, among other factors. Leases are outside of the scope of ASC 606 and are therefore accounted for in accordance with ASC 842, Leases. A STL would result in earlier recognition of instrument revenue as compared to an OTL, which is generally upon installation of the instruments. Instrument lease revenue for our OTL subscription agreements is recognized on a straight-line basis over the life of the lease and is included with the predominant non-lease components in consumables revenue. For instrument only OTL agreements, operating lease income is

-69-

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

recognized on a straight-line basis over the term of the lease. The cash collected under both arrangements is over the term of the contract. The OTLs and STLs are not cancellable until after an initial term. See below for additional information on our lease accounting policies.

For contracts with both lease and non-lease components, the Company allocates the contracts' transaction price for each component on a relative standalone selling price basis using our best estimate of the standalone selling price of each distinct product or service in the contract. When available, the method used to estimate the standalone selling price is the price observed in standalone sales to customers. When prices in standalone sales are not available, we use a cost-plus margin approach. Changes in these values can impact the amount of consideration allocated to each component of the contract. Allocation of the transaction price is determined at the contracts' inception. The Company does not adjust the transaction price for the effects of a significant financing component when the period between the transfer of the promised good or service to the customer and payment for that good or service by the customer is expected to be one year or less.

To the extent the transaction price includes variable consideration, such as future payments based on consumable usage over time, we apply judgment to determine if the variable consideration should be constrained. As the variable consideration is highly susceptible to factors outside of the Company’s influence, and the potential values contain a broad range of possible outcomes given all potential amounts of consumption that could occur, it is likely that a significant revenue reversal would occur should the variable consideration be estimated at an amount greater than the minimum stated amount until such a time as the uncertainty is resolved. For our subscription agreements with variable consideration based on consumable usage over time, the variable consideration is allocated to the non-lease components upon resolution of the uncertainty and is included in consumables revenue.

We generate OVP revenue through contract manufacturing agreements with customers. Revenue from these customer contracts is generally recognized upon shipment or acceptance by our customer, under the same guidelines noted above for other outright product sales. Heska assessed the over-time criteria within ASC 606 and concluded that while 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. Therefore, point in time revenue recognition has been determined to be appropriate.

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 and intent to make payments in accordance with arrangements. For contracts with multiple performance obligations, we exercise judgment in allocating the transaction price for each performance obligation based on an estimated standalone selling price for each distinct product or service. We do not generally allow return of products or instruments. Distributor rebates are recorded as a reduction to revenue.

Refer to Note 2 for additional disclosures required by ASC 606.

Leases

The Company acts as a lessee and a lessor. As a lessee, the Company leases buildings, office equipment, and vehicles. As a lessor, the Company enters into sales-type and operating leases as part of its subscription agreements.

The Company determines if an arrangement is a lease at inception based on whether control of an identified asset is transferred. For leases where the Company is the lessee, ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based

-70-

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit interest rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as amortization expense and interest expense. The Company has lease agreements which require payments for lease and non-lease components and has elected to account for these as a single lease component for our building and office equipment leases, but as separate components for our vehicle leases.

As a lessor, our subscription agreements relate to both OTL arrangements and STL arrangements. For a STL, instrument revenue is generally recorded upon installation of the instruments and the cost of the customer-leased instruments is removed from inventory and recognized in the Consolidated Statements of (Loss) Income. There is no residual value taken into consideration as it does not meet our capitalization requirements. For our OTL agreements that include both lease and non-lease components, revenue is recognized on a straight-line basis over the term of the lease and is included with the predominant non-lease components in consumables revenue. For instrument only OTL agreements, operating lease income is recognized on a straight-line basis over the term of the lease. For an OTL, the costs of customer-leased instruments are recorded within property and equipment in the accompanying Consolidated Balance Sheets and depreciated over the instrument’s estimated useful life. The depreciation expense is reflected in cost of revenue in the accompanying Consolidated Statements of (Loss) Income.

For leases that commenced before the January 1, 2019 effective date of ASC 842, the Company elected the permitted practical expedients to not reassess the following: (i) whether any expired or existing contracts contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases. The Company also elected to exclude leases with a term of 12 months or less from the recognized ROU assets and lease liabilities.

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 requisite service period of the award generally using the straight-line method.

Advertising Costs

Advertising costs are expensed as incurred and are included in sales and marketing expenses. Advertising expenses were $0.4 million for the year ended December 31, 2020, $0.3 million for the year ended December 31, 2019, and $0.2 million for the year ended December 31, 2018.

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 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 certain foreign subsidiaries is the local currency. Accordingly, assets and liabilities of these subsidiaries 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. Gains and losses arising from intercompany foreign currency transactions that are of a long-term investment nature are reported as a component of Accumulated other comprehensive income in the Consolidated Balance Sheets.

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. Extended warranties are sold to our customers and revenue is recognized over the term of the warranty agreement, as expected costs are incurred.

Correction of an Immaterial Error

During the fourth fiscal quarter of 2020, the Company recorded an out-of-period adjustment that impacted the Consolidated Balance Sheets, Consolidated Statements of (Loss) Income and Consolidated Statements of Comprehensive (Loss) Income. The adjustment related to an error in the calculation of non-cash interest expense relating to the Company's Notes. This error resulted in an overstatement of non-cash interest expense of $0.7 million in 2019, $0.6 million in each of the first and second fiscal quarters of 2020 and $0.5 million in the third fiscal quarter of 2020. The error also resulted in an overstatement of Convertible Notes, net, and Deferred Tax Liability of $0.7 million and $0.2 million, respectively as of December 31, 2019; $1.4 million and $0.3 million, respectively, as of March 31, 2020; $2.0 million and $0.4 million, respectively, as of June 30, 2020; and $2.5 million and $0.6 million, respectively, as of September 30, 2020. The Company assessed the materiality of these errors on the previously issued interim and annual financial statements in accordance with SEC Staff Accounting Bulletin No. 99 and No. 108. The Company concluded that the errors were not material to any of the previously issued consolidated financial statements and the impact of correcting these errors in the year ended December 31, 2020 is not material to the consolidated financial statements.

The impact of this adjustment resulted in a fourth quarter period decrease in interest expense of $2.5 million and a decrease in income tax benefit of $0.6 million. The Company also recorded a decrease in Convertible Notes, net, of $2.5 million, and a reduction in Deferred Tax Liability of $0.6 million as of December 31, 2020.

Adoption of New Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326), which requires 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. Subsequent to the issuance of ASU 2016-13, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, in November 2018. This ASU clarifies that receivables from operating leases are accounted for using the lease guidance and not as financial instruments. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, which further clarifies and improves guidance related to accounting for credit losses. In May 2019, the FASB issued ASU 2019-05, Financial Instruments - Credit Losses (Topic 326). This ASU provides relief to certain entities adopting ASU 2016-13. The amendment provides entities with an option to irrevocably elect the fair value option for certain financial assets. The Company adopted ASU 2016-13 with a cumulative-effect adjustment in retained earnings as of January 1, 2020. The impact of the adoption was not material to the Company's consolidated financial statements.

Accounting Pronouncements Not Yet Adopted    

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to the accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740, and also clarifies and amends existing guidance to improve consistent application. This guidance will be effective for interim and annual periods beginning after December 15, 2020, and early adoption is permitted. We evaluated the impact of the standard on our consolidated financial statements and do not expect the standard to have a material impact on our consolidated financial statements and disclosures.

In January 2020, the FASB issued ASU 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815). The amendments in this ASU clarify the interaction between the accounting for investments in equity securities, investment in equity method and certain derivatives instruments. The ASU is expected to reduce diversity in practice and increase comparability of the accounting for these interactions. This guidance will be effective for fiscal years beginning after December 15, 2020. We evaluated the impact of the standard on our consolidated financial statements and do not expect the standard to have a material impact on our consolidated financial statements and disclosures.

In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40), which simplifies the accounting for certain convertible instruments. The update reduces the number of accounting models for convertible debt instruments and convertible preferred stock. Convertible debt will be accounted for as a single liability measured at its amortized cost and convertible preferred stock will be accounted for as a single equity instrument measured at its historical cost, as long as no other features require bifurcation and recognition as derivatives. The update also requires the if-converted method to be used for convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. The guidance may be early adopted for fiscal years beginning after December 15, 2020,

and interim periods within those fiscal years.

The Company has elected to early adopt ASU 2020-06 as of January 1, 2021. The Notes are a convertible instrument with a cash-conversion feature that is accounted for within the scope of ASC 470-20 and will be impacted by adopting ASU 2020-06. The Company has elected to apply the modified retrospective method wherein the Company will recognize a cumulative-effect adjustment to the opening balance of retained earnings (January 1, 2021). Further, the Company will not restate EPS in the prior periods. The Company calculated the cumulative-effect adjustment as of January 1, 2021 by comparing (i) the historical amortization schedule for the Notes through December 31, 2020 and (ii) an updated amortization schedule wherein the conversion feature within the Notes would not be separated as an equity component and subsequently recognized as non-cash interest expense under ASC 835-30. As a result of ASU 2020-06, while cash interest expense is not impacted, non-cash interest accretion is limited to the amortization of debt issuance costs under ASC 835-30. Therefore, the Company prepared its transition journal entries by (i) reversing the conversion feature amount recorded in APIC and (ii) reversing the difference in non-cash interest expense via retained earnings. The expected impact on retained earnings is $4.3 million.

In October 2020, the FASB issued ASU 2020-10, Codification Improvements, which updates various codification topics by clarifying or improving disclosure requirements to align with the SEC's regulations. This guidance will be effective for annual periods beginning after December 15, 2020, for public entities. The Company will adopt as of the reporting period beginning January 1, 2021. We evaluated the impact of the

standard on our consolidated financial statements and do not expect the standard to have a material impact on our consolidated financial statements and disclosures.

Remaining Performance Obligations

Remaining performance obligations represent the aggregate transaction price allocated to performance obligations with an original contract term greater than one year which are fully or partially unsatisfied at the end of the period. Remaining performance obligations include noncancelable purchase orders, the non-lease portion of minimum purchase commitments under long-term supply arrangements, extended warranty, service and other long-term contracts. Remaining performance obligations do not include revenue from contracts with customers with an original term of one year or less, revenue from long-term supply arrangements with no minimum purchase requirements, revenue expected from purchases made in excess of the minimum purchase

requirements, or revenue from instruments leased to customers. While the remaining performance obligation disclosure is similar in concept to backlog, the definition of remaining performance obligations excludes leases and contracts that provide the customer with the right to cancel or terminate for convenience with no substantial penalty, even if historical experience indicates the likelihood of cancellation or termination is remote. Additionally, the Company has elected to exclude contracts with customers with an original term of one year or less from remaining performance obligations.

As of December 31, 2020, the aggregate amount of the transaction price allocated to remaining minimum performance obligations was approximately $144.6 million. As of December 31, 2020, the Company expects to recognize revenue as follows (in thousands):

Year Ending December 31,	Revenue
2021	$	32,976
2022	30,089
2023	26,992

Contract Balances

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled contract assets, deferred revenue, and customer deposits and billings in excess of revenue recognized. In addition, the Company defers certain costs incurred to obtain contracts.

Contract Assets

Certain unbilled amounts related to long-term contracts for which we provide a free term to the customer are recorded in "Other current assets" and "Other non-current assets" on the accompanying Consolidated Balance Sheets. The collection of these balances occurs over the term of the underlying contract. The balances as of December 31, 2020 were $1.2 million and $4.1 million for current and non-current assets, respectively, shown net of related unearned interest. The balances as of December 31, 2019 were $1.1 million and $3.7 million for current and non-current assets, respectively, shown net of related unearned interest.

Contract Liabilities

The Company receives cash payments from customers for licensing fees or other arrangements that extend for a specified term. These contract liabilities are classified as either current or long-term in the Consolidated Balance Sheets based on the timing of when the Company expects to recognize revenue. As of December 31, 2020 and 2019, contract liabilities were $8.9 million and $8.7 million, respectively, and are included within "Deferred revenue, current, and other" and "Deferred revenue, non-current" in the accompanying Consolidated Balance Sheets. The decrease in the contract liability balance during the year ended December 31, 2020 is approximately $4.2 million of revenue recognized during the period, offset by approximately $3.8 million of additional deferred sales in 2020 and the acquisition of scil contract liabilities of $0.6 million. The decrease in the contract liability balance during the year ended December 31, 2019 is $3.1 million of revenue recognized during the period, offset by $2.2 million of additional deferred sales. Contract liabilities are reported on the accompanying Consolidated Balance Sheets on a contract-by-contract basis.

Contract Costs

The Company capitalizes certain direct incremental costs incurred to obtain customer contracts, typically sales-related commissions, where the recognition period for the related revenue is greater than one year. Contract costs are classified as current or non-current, and are included in "Other current assets" and "Other non-current assets" in the Consolidated Balance Sheets based on the timing of when the Company expects to recognize the expense. Contract costs are generally amortized into selling and marketing expense with a certain percentage recognized immediately based upon placement of the instrument with the remainder recognized on a straight-line basis (which is consistent with the transfer of control for the related goods or services) over the average term of the underlying contracts, approximately 6 years. Management assesses these costs for impairment at least quarterly on a portfolio basis and as “triggering” events occur that indicate it is more-likely-than-not that an impairment exists. The balance of contract costs as of December 31, 2020 and December 31, 2019 was $3.0 million and $2.7 million, respectively. Amortization expense for the year ended December 31, 2020 was approximately $1.0 million, offset by approximately $1.2 million of additional contract cost capitalization and $0.1 million of the acquisition of scil contract costs. Amortization expense for the year ended December 31, 2019 was approximately $0.9 million, offset by approximately $1.1 million of additional contract costs capitalized. Contract costs are calculated and reported on a portfolio basis.

3.    ACQUISITION AND RELATED PARTY ITEMS

scil Acquisition

On April 1, 2020, the Company completed the acquisition of scil animal care company GmbH (“scil”) from Covetrus, Inc. The Company purchased 100% of the capital stock of scil for an aggregate purchase price of $110.3 million in cash. The acquisition represents a key milestone in the Company's long-term strategic plan, creating a global veterinary diagnostics company with leadership positions in key geographic markets. The purchase price exceeded the identifiable net assets, resulting in goodwill of $46.0 million, primarily attributable to the synergies expected from the expanded market opportunities with our offerings and the experienced workforce acquired. Of the goodwill acquired, $37.3 million is allocated to our International segment and $8.7 million is allocated to our North America segment. All of the goodwill is tax deductible for purposes of calculating Controlled Foreign Corporation ("CFC") tested income, which may result in a decrease to the Company's future U.S. federal tax liability.

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

The acquisition was accounted for using the acquisition method of accounting in accordance with ASC 805, Business Combinations, which requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. As such, the total purchase consideration was allocated to the assets acquired and liabilities assumed based on a preliminary estimate of their fair values as of April 1, 2020.

The information below represents the preliminary purchase price allocation of scil (in thousands):

	April 1, 2020
Total purchase consideration	$	110,290
Cash and cash equivalents	5,889
Accounts receivable	10,707
Inventories	11,278
Net investment in leases, current	311
Prepaid expenses	1,692
Other current assets	1,338
Property and equipment, net	19,320
Operating lease right-of-use assets	877
Other intangible assets, net	44,517
Net investment in leases, non-current	1,027
Investments in unconsolidated affiliates	55
Other non-current assets	291
Total assets acquired	97,302
Accounts payable	8,221
Accrued liabilities	7,067
Operating lease liabilities, current	356
Deferred revenue, current, and other	3,220
Deferred revenue, non-current	94
Operating lease liabilities, non-current	529
Deferred tax liability	13,249
Other liabilities	276
Net assets acquired	64,290
Goodwill	46,000
Total fair value of consideration transferred	$	110,290

The Company's preliminary estimates of fair values of the assets acquired and the liabilities assumed are based on the information currently available, and the Company is continuing to evaluate the underlying inputs and assumptions used in its valuations. Accordingly, these preliminary estimates are subject to change during the measurement period, which is up to one year from the date of the acquisition. A decrease in the fair value of assets acquired or an increase in the fair value of liabilities assumed in the acquisition from those valuations would result in a corresponding change in the amount of goodwill from the acquisition. During the fourth quarter, the Company made certain valuation adjustments to provisional amounts previously recognized. These adjustments resulted in a net increase of $0.2 million in goodwill, primarily due to changes in estimated taxes and an increase in accrued liabilities assumed.

Per the tax indemnification included in the purchase agreement of scil animal care company GmbH, the seller has indemnified the Company for $1.1 million related to uncertain tax positions taken in prior years. The outcome of this arrangement will either be settled or expire due to lapse of statute of limitations by 2027. As of December 31, 2020, approximately $0.8 million of the indemnification agreement remains outstanding.

Intangible assets acquired, amortization method and estimated useful life as of April 1, 2020, was as follows (dollars in thousands):

scil generated net revenue of $61.3 million and a net loss of $1.1 million for the period from April 1, 2020 to December 31, 2020.

The Company incurred acquisition related costs of approximately $6.3 million and $0.7 million for the years ended December 31, 2020 and 2019, respectively, which are included within general and administrative expenses on our Consolidated Statements of (Loss) Income.

CVM

On December 5, 2019, Heska entered into a definitive agreement to purchase 100% of the outstanding shares of CVM Diagnostico Veternario S.L. and CVM Ecografia S.L. (“CVM”, collectively), primarily to expand international operations in Europe. CVM is headquartered in Tudela, outside of Madrid, Spain. CVM mainly

operates in Spain. The terms of the agreement transferred control of CVM upon signing, and the transfer of the purchase price of approximately $14.4 million and shares occurred in January 2020. The purchase price exceeded the fair value of the identifiable net assets and, accordingly, $9.0 million was allocated to goodwill within the International segment based on the purchase price allocation, all of which is tax deductible for purposes of calculating CFC tested income.

The fair values allocated to CVM's assets and liabilities as of the acquisition date, as well as the purchase price, are reflected in the table below (in thousands):

During the year ended December 31, 2020, the Company made certain valuation adjustments to provisional amounts previously recognized. These measurement period adjustments resulted in a net $110 thousand increase of goodwill, primarily due to fair value adjustments resulting in a decrease in net identifiable assets acquired. The Company finalized the accounting for the CVM acquisition in the fourth quarter of 2020.

Intangible assets acquired, amortization method and estimated useful life as of December 5, 2019, were as follows (dollars in thousands):

Optomed

On February 22, 2019, Heska acquired 70% of the equity of Optomed, a French-based endoscopy company, in exchange for approximately $0.2 million in cash and the assumption of approximately $0.4 million in debt. On October 5, 2020, the Company acquired the remaining 30% minority interest in Optomed for a purchase price of $0.5 million, allowing the Company to assume full control of the business operations.

Purchase Agreement for Certain Assets

Cuattro, LLC ("Cuattro") is owned by Kevin S. Wilson, the CEO and President of the Company. On December 21, 2018, the Company closed a transaction (the "Asset Acquisition") to acquire certain assets from Cuattro, all related to the North America segment. Pursuant to the Asset Acquisition, dated November 26, 2018, the Company issued 54,763 shares of the Company's common stock, $0.01 par value per share (the "Common Stock"), to Cuattro on the Closing Date, at an aggregate value equal to approximately $5.4 million based on the adjusted closing price per share of the Common Stock as reported on the Nasdaq Stock Market on the Asset Acquisition agreement date. These shares were issued to Cuattro in a private placement in reliance upon an exemption from the registration requirements of the Securities Act pursuant to Section 4(a)(2) thereof and the safe harbor provided by Rule 506 of Regulation D promulgated thereunder. In addition to the Common Stock, the Company paid cash in the amount of $2.8 million to Cuattro as part of the transaction. The total purchase price was determined based on a valuation report from an independent third party. Part of the Asset Acquisition was an agreement to terminate the supply and license agreement that Heska had been operating under since the acquisition of Cuattro Veterinary USA, LLC.

The Company evaluated the acquisition of the purchased assets under ASC 805, Business Combinations and ASU 2017-01, Business Combinations (Topic 805) and concluded that as substantially all of the fair value of the gross assets acquired is concentrated in an identifiable group of similar assets, the transaction did not meet the requirements to be accounted for as a business combination and therefore was accounted for as an asset

acquisition. Accordingly, the $8.2 million purchase price of the purchased assets was allocated entirely to an identifiable intangible asset amortizing on a straight-line basis over a 10-year useful life.

Related Party Activities

Cuattro charged the Company $0, $6 thousand and $4.6 million during 2020, 2019 and 2018, respectively, primarily related to digital imaging products, pursuant to an underlying supply contract that contained minimum purchase obligations, software and services as well as other operating expenses. Pursuant to the Asset Acquisition, Cuattro was obligated, without further compensation, to assist the Company with the implementation of a third-party image hosting platform and necessary data migration. The implementation and migration were completed, and as of December 31, 2020 there will be no further related party activities with Cuattro.

CVM management conducts related party activities with Practice Clinicas Veterinarias Moviles, S.L. ("CVM Practice"), which is owned by CVM's management. During the year ended December 31, 2020, the Company fully paid the balance of a loan due to CVM Practice of approximately $1.1 million, which is included in "Payments of related party debt" on the Consolidated Statements of Cash Flows. CVM also leases two warehouses from CVM Practice. CVM Practice charged CVM $31 thousand and $0 during the year ended December 31, 2020 and 2019, respectively, all of which is related to lease payments. The right-of-use asset and lease liability amounts related to the warehouse leases were approximately $0.2 million and $0 as of December 31, 2020 and 2019, respectively. The change from December 31, 2019 to December 31, 2020 is due to a reorganization regarding CVM management and the control that they exercise subsequent to the scil acquisition.

Equity Method Investment

On September 24, 2018, we invested approximately $5.1 million, including costs, to acquire an equity interest in a business as part of our product development strategy. As of December 31, 2020, our ownership interest in the business was 29.1%. In connection with the investment, the Company entered into a Manufacturing Supply Agreement that grants the Company global exclusivity to specified products to be delivered under the agreement for a 15-year period that begins upon the Company's receipt and acceptance of an initial order under the agreement. The Company accounts for this investment using the equity method of accounting. Under the equity method, the carrying value of the investment is adjusted for the Company's proportionate share of the investee's reported earnings or losses with the corresponding share of earnings or losses reported as Equity in losses of unconsolidated affiliates, listed below Net income before equity in losses of unconsolidated affiliates within the Consolidated Statements of (Loss) Income.

Non-Marketable Equity Security Investment

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

On August 8, 2018, the Company invested approximately $3.0 million, including costs, in exchange for preferred stock. The Company's investment is a non-marketable equity security, recorded using the measurement alternative of cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes.

As part of the agreement, the Company entered into a Supply and License Agreement, which provides that the investee produce and commercialize products that will enhance the Company's diagnostic portfolio. As part of this agreement, the Company made upfront payment of $1.0 million related to a worldwide exclusive license agreement over a 20-year period, recorded in both short and long-term other assets. In addition, the agreement provides for an additional contingent payment of $10.0 million, relating to the successful achievement of sales milestones. This potential future milestone payment has not yet been accrued as it is not deemed by the Company to be probable at this time.

Both parties in this arrangement are active participants and are exposed to significant risks and rewards dependent on the commercial success of the activities of the collaboration. The parties are actively working on developing and testing the product as well as funding the research and development. Heska classifies the amounts paid for research and development work within the North America segment research and development operating expenses. Expense is recognized ratably when incurred and in accordance with the development plan.

Our investments are evaluated for impairment if a triggering event occurs. The Company evaluated both its equity method investment and non-marketable equity security investment for losses other than temporary as of December 31, 2020, and determined that no indications of an impairment existed.

In 2019, we had total income tax benefit of $1.4 million, including approximately $1.9 million in domestic deferred income tax benefit and $0.1 million of foreign deferred income tax expense, a non-cash benefit, and approximately $0.4 million in current income tax expense. In 2018, we had total income tax benefit of $2.1 million, including $2.3 million in domestic deferred income tax benefit, a non-cash benefit, and $0.1 million in current income tax expense. Income tax expense increased in 2020 from 2019 due to foreign income inclusion, executive compensation limitations and acquisition related costs. Income tax benefit decreased in 2019 from 2018 due to executive compensation limitations and lower excess tax benefits related to stock-based compensation deductions.

Cash paid for income taxes for the years ended December 31, 2020, 2019 and 2018 was $993 thousand, $128 thousand and $36 thousand, respectively.

HESKA CORPORATION AND SUBSIDIARIES

The Company is subject to income taxes in the U.S. 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. Although the U.S. and many states generally have statutes of limitations ranging from 3 to 5 years, those statutes could be extended due to the Company’s net operating loss and tax credit carryforward positions in several of the Company's tax jurisdictions. In the U.S., the tax years 2017 - 2019 remain open to examination by the Internal Revenue Service.

As of December 31, 2020, the Company had net operating loss carryforwards ("NOL") of approximately $35.0 million, a foreign tax credit of $64 thousand and a domestic research and development tax credit carryforward of approximately $1.3 million. Our federal NOL is expected to expire as follows if unused: $22 million in 2021 through 2022, $5.4 million in 2024 through 2025 and $0.5 million in 2027 and later. Our foreign NOL of $7.1 million does not have an expiration date.

The Company considered multiple factors in assessing the need for an increase in the partial valuation allowance against the Company’s deferred tax assets as of December 31, 2020. Significant factors such as employee stock compensation expenses from achievement of Company performance metrics, executive compensation limitations and required capitalization of research and development expenses beginning in 2022 have negatively impacted our future taxable income projections. These future projections indicate a larger portion of the Company’s deferred tax assets will likely expire unrealized. As a result, the Company recorded an additional $0.8 million tax effected increase to the current partial valuation allowance against the Company's worldwide net operating losses and tax credits for the year ended December 31, 2020. As of December 31, 2020, the Company had a deferred tax asset of approximately $10.1 million from net operating losses and tax credits and a net partial valuation allowance of approximately $6.4 million recorded against these deferred tax assets. The Company will continue to closely monitor the need for an additional valuation allowance against its deferred tax assets in each subsequent reporting period which can be impacted by actual operating results compared to the Company's forecast.

ASC Topic 740 prescribes the accounting for uncertainty in income taxes recognized in the financial statements in accordance with the other provisions contained within this guidance. This topic prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by the taxing authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50% likely or being realized upon ultimate audit settlement. In the normal course of business, the Company's tax returns are subject to examination by various taxing authorities. Such examination may result in future tax and interest assessments by these taxing authorities for uncertain tax positions taken in respect to certain matters.

The total amount of unrecognized tax benefits, which are included in other liabilities within the combined balance sheets as of December 31, 2020 was approximately $0.8 million, which may impact the effective tax rate if recognized. These unrecognized tax benefits were recognized as part of the acquisition of scil animal care company GmbH. Per the tax indemnification included in the purchase agreement, the seller has indemnified the Company for these other liabilities, which would reduce the economic impact to the Company if these positions were settled with tax authorities. It is expected that the amount of unrecognized tax benefits will change in the next 12 months; however, the Company does not expect the change to have a material impact on the combined financial statements. The Company recognizes interest and penalties related to uncertain tax positions in income tax (benefit)/expense. Interest and penalties accrued as of December 31, 2020 are $19.0 thousand.

As of December 31, 2020, the Company had accumulated undistributed earnings generated by foreign subsidiaries of approximately $2.9 million, which would be subject to U.S. taxes and foreign withholding taxes of approximately $145 thousand if repatriated. The Company had previously considered these earnings as a possible cash source through repatriation to the U.S. As of December 31, 2020, the Company has changed its assertion on these earnings and now considers them to be indefinitely reinvested and expects the future U.S. cash generation to be sufficient to meet future U.S. cash needs. If the Company decides to repatriate these foreign earnings, it would need to adjust its income tax provision in the period it determined that the earnings would no longer be indefinitely invested outside the United States.

7.    EARNINGS PER SHARE

Basic earnings per share ("EPS") is computed by dividing net income attributable to the Company 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 awards 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 following is a reconciliation of the weighted-average shares outstanding used in the calculation of basic and diluted earnings per share ("EPS") for the years ended December 31, 2020, 2019 and 2018 (in thousands, except per share data):

	Years ended December 31,

Diluted (loss) earnings per share attributable to Heska Corporation	$	(1.66)	$	(0.20)	$	0.74

The following potentially outstanding common shares from convertible preferred stock, convertible senior notes, stock options and restricted stock awards were excluded from the computation of diluted EPS because the effect would have been antidilutive (in thousands):

Convertible preferred stock	458	—	—
Convertible senior notes	118	—	—
Stock options and restricted shares	328	300	111
	904	300	111

As more fully described in Note 16, our Notes are convertible under certain circumstances, as defined in the indenture, into a combination of cash and shares of our common stock. The Company intends to settle the principal value of the Notes in cash and issue shares of our common stock to settle the intrinsic value of the conversion feature. The Company will use the treasury stock method when calculating the potential dilutive effect of the conversion feature on earnings per share, if any. Potential dilution upon conversion of the Notes occurs when the average market price per share of our common stock is greater than the conversion price of the Notes of $86.63. For the periods presented, all potentially dilutive shares relating to the Notes were not included in the computation of diluted EPS as the effect would have been antidilutive.

As discussed in Note 12, the Company issued and sold an aggregate of 122,000 shares of its Preferred Stock to certain investors in a private placement offering. The shares were converted into 1,508,964 shares of Public Common Stock, effective on April 21, 2020. The potential dilutive effect of the convertible preferred stock was calculated using the if-converted method for the period the preferred shares were outstanding. For the twelve months ended December 31, 2020, these shares were excluded from the computation of diluted EPS because the effect would have been antidilutive.

12.    CAPITAL STOCK

Stock Plans

We have two stock option plans which authorize granting of stock options, restricted stock awards 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"), which was later amended in December 2018 to be renamed the "Stock Incentive Plan." In May 2012, stockholders approved an amendment 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. The plan was further amended in May 2016, May 2018, and April 2020 to increase the number of shares authorized for issuance by 500,000, 250,000, and 300,000 shares, respectively. 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, 2020 was 151,605.

Stock Options

The stock options granted by the Board of Directors may be either incentive stock options ("ISOs") or non-qualified stock options ("NQs") and may include time-based vesting terms and/or be tied to Company and market-related performance metrics. The exercise price for options under all of the plans may be no less than

-94-

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

100% of the fair value of the underlying common stock. 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 Stock Incentive Plan, in the event we are sold or merged, outstanding options will either be assumed by the surviving corporation or vest immediately.

We use the Black-Scholes option-pricing model to estimate the fair value of time-vested and performance stock options granted, which includes four key inputs: expected term, expected volatility, risk-free interest rate and expected dividends. Our expected term is estimated based on historical exercise patterns. Our expected volatility input was estimated based on our historical stock price volatility. Our risk-free interest rate input was determined based on the U.S. Treasury yield curve at the time of option issuance. Our expected dividends inputs were zero in all periods as we did not anticipate paying dividends in the foreseeable future. For options tied to market performance, the fair value used in our expense recognition method is measured based on the number of shares granted, and a Monte Carlo simulation model, which incorporates the probability of the achievement of the market-related performance goals as part of the grant date fair value. We recognize forfeitures as they occur.

Time Vesting Stock Options

The fair value of each time vesting option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:

	2020	2019	2018
Risk-free interest rate	3.64%	1.62%	2.66%
Expected lives	5.3 years	4.7 years	4.9 years
Expected volatility	46%	40%	40%
Expected dividend yield	0%	0%	0%

A summary of our time vesting stock option activity is as follows:

	Year Ended December 31,
	2020
	Options	Weighted Average Exercise Price
Outstanding at beginning of period	536,315	$	54.86
Granted at market	83,250	$	69.27
Forfeited	(42,307)	$	76.24
Expired	(28,691)	$	69.25
Exercised	(84,335)	$	40.64
Outstanding at end of period	464,232	$	57.18
Exercisable at end of period	291,334	$	46.53

The total estimated fair value of time vesting stock options granted was computed to be approximately $2.4 million, $2.6 million and $4.4 million during the years ended December 31, 2020, 2019 and 2018, 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 $28.66, $29.89 and $28.81 during the years ended December 31, 2020, 2019 and 2018, respectively. The total intrinsic value of options

exercised was $5.0 million, $12.8 million and $10.5 million during the years ended December 31, 2020, 2019 and 2018, respectively. The cash proceeds from options exercised were $3.4 million, $1.0 million and $3.2 million during the years ended December 31, 2020, 2019 and 2018, respectively.

The following table summarizes information about time vesting stock options outstanding and exercisable at December 31, 2020.

As of December 31, 2020, there was approximately $3.6 million of total unrecognized compensation cost related to outstanding stock options. That cost is expected to be recognized over a weighted-average period of 1.63 years with all cost to be recognized by the end of August 2023, assuming all options vest according to the vesting schedules in place at December 31, 2020. As of December 31, 2020, the aggregate intrinsic value of outstanding options was approximately $41.1 million and the aggregate intrinsic value of exercisable options was approximately $28.9 million.

Performance Stock Options

On April 16, 2020, the Company granted a total of 240,000 performance-based stock options all with an exercise price of $60.94. Of the options granted,10,000 are tied to market-related vesting conditions and 230,000 are tied to Company performance metrics, including future product launches, future sales targets, operating performance, and EBITDA. Performance and market conditions must be achieved by December 31, 2023 otherwise the stock options are forfeited. All vested but unexercised options will expire April 15, 2030.

During the year ended December 31, 2020, 20,000 of the performance-based stock options were forfeited, leaving a total of 220,000 options outstanding as of December 31, 2020. The outstanding options had a weighted-average exercise price of $60.94, a weighted-average remaining contractual term of 9.29 years, and an aggregate intrinsic value of approximately $18.6 million. No options were exercisable as of December 31, 2020. For the year ended December 31, 2020, the weighted-average estimated fair value of the options granted was computed to be approximately $25.04 and the total estimated fair value was approximately $6.0 million. As of December 31, 2020, there was approximately $2.4 million of total unrecognized compensation cost that is expected to be recognized over a weighted average period of 1.80 years.

As of December 31, 2020, we reviewed each of the underlying corporate performance targets and determined that approximately 80,000 shares were related to corporate performance targets in which we did not deem achievement probable. No compensation expense had been recorded at any period prior to December 31, 2020. The unrecognized compensation cost associated with the performance options not deemed probable, based on grant date fair value, is approximately $2.0 million. Any change in the probability determination could accelerate the recognition of this expense.

Restricted Stock Awards

We have granted unvested restricted stock awards (“restricted stock”) to management and directors pursuant to the Stock Incentive Plan. The restricted stock awards have varying vesting periods, but generally become fully vested between one and four years after the grant date, depending on the specific award, performance targets met for performance based awards granted to management, and vesting period for time based awards. Management performance based awards are granted at the target amount of shares that may be earned and are tied to future sales targets, operating performance, and/or EBITDA. We valued the restricted stock awards related to service and/or company performance targets based on grant date fair value and expense over the period when achievement of those conditions is deemed probable. For restricted stock awards related to market conditions, we utilize a Monte Carlo simulation model to estimate grant date fair value and expense over the requisite period. We recognize forfeitures as they occur.

The following table summarizes restricted stock transactions for the year ended December 31, 2020:

	Restricted Stock	Weighted-Average Grant Date Fair Value Per Award
Non-vested as of December 31, 2019	335,667	$	74.29
Granted	69,823	$	87.29
Vested	(46,140)	$	68.80
Forfeited	(67,830)	$	73.27
Non-vested as of December 31, 2020	291,520	$	78.44

The weighted average grant date fair value of awards granted during the year was $87.29, $74.93, and $71.77 for the years ended December 31, 2020, 2019 and 2018, respectively. Fair value of restricted stock vested was $5.0 million, $0.3 million, and $4.4 million for the years ended December 31, 2020, 2019 and 2018, respectively.

As of December 31, 2020, there was approximately $5.5 million of total unrecognized compensation cost related to restricted stock awards with probable Company performance targets, as well as market and time vesting conditions. The Company expects to recognize this expense over a weighted average period of 1.4 years. As of December 31, 2020, we reviewed each of the underlying corporate performance targets and determined that approximately 129,000 shares of common stock were related to corporate performance targets in which we did not deem achievement probable. No compensation expense had been recorded at any period prior to December 31, 2020. The unrecognized compensation cost associated with the restricted stock awards not deemed probable, based on grant date fair value, is approximately $10.6 million. Any change in the probability determination could accelerate the recognition of this expense.

Employee Stock Purchase Plan

Under the 2020 Employee Stock Purchase Plan (the "ESPP"), we are authorized to issue up to 200,000 shares of common stock to our employees, of which 3,859 had been issued as of December 31, 2020. The ESPP provides for the issuance of shares of our common stock to participating employees. At the end of each designated offering period, which occurs every six months on June 30 and December 31, employees can elect to purchase shares of our common stock with contributions of up to 10% of their base pay, accumulated via payroll deductions, at an amount equal to 85% of the lower of our stock price on (i) the first trading day of the offering period, or (ii) the last trading day of the offering period.

We issued 10,069, 10,698 and 10,078 shares under the ESPP for the years ended December 31, 2020, 2019 and 2018, respectively. The weighted-average fair value of the purchase rights granted was $16.19, $18.10 and $18.14 per share for the years ended December 31, 2020, 2019 and 2018, respectively.

Series X Convertible Preferred Stock

On March 30, 2020, the Company completed a private placement offering in which the Company issued and sold an aggregate of 122,000 shares of its Series X Convertible Preferred Stock, par value $0.01 per share (the "Preferred Stock"). The shares of Preferred Stock issued and sold were priced at $1,000 per share (the “Stated Value”), resulting in gross proceeds of $122.0 million, less issuance costs of $0.2 million. The Company used approximately $111.0 million of the proceeds from the offering to fund the April 1, 2020 acquisition of scil and plans to use the remaining proceeds for working capital and general corporate purposes.

The offering was made pursuant to the Securities Purchase Agreement (the “Securities Purchase Agreement”), dated as of January 12, 2020, by and among the Company and certain investors, and subsequent amendment (the “Securities Purchase Agreement Amendment”) to the Securities Purchase Agreement, entered into by the Company and each investor on March 30, 2020 (the Securities Purchase Agreement as amended by the Securities Purchase Agreement Amendment, the “Amended Securities Purchase Agreement”).

The shares of Preferred Stock were convertible into shares of the Company’s Common Stock at an initial ratio of approximately 12.4 shares of Common Stock for each share of Preferred Stock (equivalent to a conversion price of approximately $80.85 per share of common stock), at the option of the holders of the Preferred Stock or the Company, subject to the Company possessing sufficient unissued and otherwise unreserved shares of Common Stock under the Company’s Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”). On April 14, 2020, the Company gave notice of its exercise of its right to convert the 122,000 shares of Preferred Stock into 1,508,964 shares of Public Common Stock (the "Conversion Shares") and the conversion was effective on April 21, 2020. The conversion resulted in dilution of less than 20% of total shares of the Company’s Public Common Stock currently issued and outstanding. A registration statement on Form S-3 (File No. 333-238005) registering the Conversion Shares for resale was filed by us with the SEC on May 5, 2020.

14.    COMMITMENTS AND CONTINGENCIES

Warranties

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 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 $0.5 million and $0.3 million as of December 31, 2020 and 2019.

Litigation

From time to time, the Company may be involved in litigation relating to claims arising out of its operations. The Company records accruals for outstanding legal matters when it believes it is probable that a loss will be incurred, and the amount can be reasonably estimated.

On February 18, 2020, a former managing director of scil filed a claim disputing the effective date of the termination of his management service agreement and the validity of the Company´s waiver of his two-year post-contractual non-compete obligation. The Company intends to defend itself against the claim. Whether or not this will be successful depends on complex facts and circumstances. The Company is, based on the advice of its legal counsel, confident that it will be successful in evidencing the effective date of the termination of the management service agreement and as such, no accrual has been recorded for this ongoing litigation. Additionally, we are indemnified by the scil acquisition agreement for this claim.

On October 10, 2018, we reached an agreement in principle to settle the complaint that was filed against the Company by Shaun Fauley on March 12, 2015 in the U.S. District Court Northern District of Illinois (the "Court") 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 (the "Fauley Complaint"). The settlement, which received the Court's approval on February 28, 2019 and was not

subsequently appealed by a class member, required us to make available a total of $6.8 million to pay class members, as well as to pay attorneys' fees and expenses to legal counsel to the class. The Company recorded the loss provision in the third quarter of 2018 in connection with the settlement agreement and does not have insurance coverage for the Fauley Complaint. The payment in respect of the settlement was made in full on April 3, 2019, and all activity related to the Fauley Complaint has ceased.

At December 31, 2020, 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.

Off-Balance Sheet Commitments

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

Purchase Obligations

The Company has contractual obligations with suppliers for unconditional annual minimum inventory purchases in the amounts of $25.0 million as of December 31, 2020.

16.    CONVERTIBLE NOTES

Convertible Notes

On September 17, 2019, the Company issued $86.25 million aggregate principal amount of 3.750% Convertible Senior Notes due 2026, which included the exercise in full of an $11.25 million purchase option, to certain financial institutions as the initial purchasers of the Notes (the "Initial Purchasers"). The Notes are senior unsecured obligations of the Company. The Notes were issued pursuant to an Indenture, dated September 17, 2019 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee.

The net proceeds from the sale of the Notes were approximately $83.7 million after deducting the initial purchasers’ discounts and the offering expenses payable by the Company. The Company used approximately $12.8 million of the net proceeds from the Notes to repay all outstanding indebtedness on its

-100-

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

existing Credit Facility with JPMorgan Chase Bank, N.A., and an additional $2.0 million to fully fund a cash collateralized, letter of credit facility under a new Credit Facility. The Company subsequently terminated the Credit Facility with JPMorgan Chase Bank, N.A. on December 31, 2019. The Company expects to use the remainder of the net proceeds from the sale of the Notes to fund our intended expansion efforts, including through acquisitions of complementary businesses or technologies or other strategic transactions, and for working capital and other general corporate purposes.

The Notes are senior unsecured obligations of the Company and will rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of our unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries.

The Company pays interest on the Notes semiannually in arrears at a rate of 3.750% per annum on March 15 and September 15 of each year. The Notes are convertible based upon an initial conversion rate of 11.5434 shares of the Company’s common stock per $1,000 principal amount of Notes (equivalent to a conversion price of approximately $86.63 per share of common stock). The Notes would convert in full into 995,618 shares of common stock based on the initial conversion rate. The conversion rate will be subject to standard anti-dilution adjustments upon the occurrence of certain events but will not be adjusted for accrued and unpaid interest. The interest rate on the Notes may be increased by up to 0.50% upon the occurrence of certain events of default or non-timely filings until such matter has been cured.

The Indenture includes customary covenants, but no financial or operating covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities, and sets forth certain events of default and certain types of bankruptcy or insolvency events of default involving the Company after which the Notes become automatically due and payable. The Company can settle any conversions of the Notes in cash, shares of the Company’s common stock or a combination thereof, with the form of consideration determined at the Company’s election. The Company intends to settle the principal value of the Notes in cash and issue shares of the Company’s common stock to settle the intrinsic value of the conversion feature. There can be no guarantee, however, that any settlement will be affected by the Company as currently intended, and the timing and other factors of any settlement, many of which may be outside the Company's control, could impact the actual amounts to be settled in either cash or common stock.

The Notes will mature on September 15, 2026, unless earlier repurchased, redeemed or converted. Prior to March 15, 2026, holders may convert all or a portion of their Notes only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on December 31, 2019 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the 5 business day period after any 5 consecutive trading day period (the "Notes measurement period") in which the trading price per $1,000 principal amount of Notes for each trading day of the Notes measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; (3) with respect to any Notes called for redemption by the Company, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On and after March 15, 2026 until the close of business on the scheduled trading day immediately preceding the maturity date, holders may convert their Notes at any time, regardless of the foregoing circumstances. Holders of Notes who convert their Notes in connection with a notice of a redemption or a make-whole fundamental change (each as defined in the Indenture) may be entitled to a premium in the form of an increase in the conversion rate of the Notes.

-101-

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

The Company may not redeem the Notes prior to September 20, 2023. On or after September 20, 2023, the Company may redeem for cash all or part of the Notes if the last reported sale price of the Company’s common stock equals or exceeds 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of the redemption. The redemption price will be 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any. No sinking fund is provided for the Notes.

Upon the occurrence of a fundamental change (as defined in the Indenture), holders may require the Company to repurchase all or a portion of their Notes for cash at a price equal to 100% of the principal amount of the Notes to be repurchased plus any accrued but unpaid interest to, but excluding, the fundamental change repurchase date.

In accounting for the issuance of the Notes, the Company separated the Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component, representing the conversion option, which does not meet the criteria for separate accounting as a derivative as it is indexed to the Company's own stock, was determined by deducting the fair value of the liability component from the par value of the Notes. The difference between the principal amount of the Notes and the liability component represents the debt discount, which is recorded as a direct deduction from the related debt liability in the Consolidated Balance Sheet and amortized to interest expense using the effective interest method over the term of the Notes. The effective interest rate of the Notes is 15.3% per annum. The equity component of the Notes is approximately $39.5 million, net of allocated issuance costs of $1.5 million. This is included in additional paid-in capital in the Consolidated Balance Sheet, net of deferred tax impacts of $9.7 million, and is not remeasured as long as it continues to meet the conditions for equity classification. The Company allocated transaction costs related to the Notes using the same proportions as the proceeds from the Notes. Transaction costs attributable to the liability component were recorded as a direct deduction from the related debt liability in the Consolidated Balance Sheet and amortized to interest expense over the term of the Notes, and transaction costs attributable to the equity component were netted with the equity component in shareholders’ equity.

In addition, the Company determined that the additional interest that could be due to the holders of the Notes upon an event of default or non-timely filing represented an embedded derivative feature that should be bifurcated from the Notes. The Company concluded that the fair value of this embedded derivative feature was de minimis upon the issuance of the Notes and at December 31, 2020.

During the years ended December 31, 2020 and 2019, no portion of the Notes was converted and the liability component was classified as long-term debt on the Company's Consolidated Balance Sheet as of December 31, 2020.

The following table summarizes the net carrying amount of the Notes as of December 31, 2020 (in thousands):

	December 31, 2020		December 31, 2019
Principal amount of the Notes	$	86,250	$	86,250

1 Refer to Note 1. Summary of Significant Accounting Policies relating to an immaterial out of period error correction of non-cash interest identified and recorded during the fourth fiscal quarter of 2020.

As of December 31, 2020, the remaining period over which the unamortized discount will be amortized is 68.5 months.

The estimated fair value of the Notes was $156.9 million as of December 31, 2020, determined through consideration of quoted market prices in less active markets. The fair value measurement is classified as Level 2 in the fair value hierarchy, which is defined in ASC 820 as inputs other than quoted prices in active markets that are either directly or indirectly observable. Based on our closing stock price of $145.65 on December 31, 2020, the if-converted value exceeded the aggregate principal amount of the Notes by $58.8 million.

17.    CONVERTIBLE NOTE RECEIVABLE

The carrying value of the note receivable, included in Related party convertible note receivable, net on the Consolidated Balance Sheets, is as follows (in thousands):

	December 31, 2020
Principal amount	$	6,650
Unamortized discount	(977)
Net carrying amount	$	5,673

On December 9, 2020, our equity method investee (the “Investee”), issued a Convertible Promissory Note to the Company (the “Convertible Promissory Note”) with a principal amount of $6.65 million and a stated interest rate of 3.0% per annum that is payable monthly. The Convertible Promissory Note has a maturity date of December 9, 2023, or otherwise upon qualified redemption event or in the event of a default. Refer to Note 4 for additional information on our equity method investment.

The conversion of the Convertible Promissory Note is contingent upon certain events. Due to the convertible debt features included in the Convertible Promissory Note, it is not an equity security and is therefore not considered an additional investment in our equity method investee. The Company accounted for the transaction as a note receivable, included in Related party convertible note receivable, net on the Consolidated Balance Sheets. The note receivable will be measured at amortized cost, and evaluated for credit losses each reporting period. The Company determined that the redemption features described above met the definition of an embedded derivative that requires bifurcation from the note receivable host. The Company measured the redemption features at fair value, with the residual proceeds paid allocated to the note receivable host, creating a discount to the note receivable. The discount will be amortized over the contractual term of the Promissory Note using the effective interest method. The effective interest rate of the Convertible Promissory Note is 8.69%, and the amortization of the discount will be included as interest income within Interest and other expense (income), net on the Consolidated Statements of Income.

The fair value of the embedded derivative was $1.0 million at issuance and as of December 31, 2020, and is included in Related party convertible note receivable, net on our Consolidated Balance Sheets. The fair value of the derivative will be remeasured each reporting period, with the mark-to-market adjustment to be included in other expense (income) on the Consolidated Statements of Income.

18.    SEGMENT REPORTING

On April 1, 2020, Heska completed the acquisition of scil. Following this acquisition, the Company restructured its operating segments based on how the Chief Operating Decision Maker (“CODM”) manages the business, allocates resources, makes operating decisions and evaluates operating performance. The CODM changed how he assesses performance and allocates resources based on geographic regions in order to better align with the global operations of the Company. Based on this change, the Company determined it has two reportable segments and revised prior comparative periods to conform to the current period segment presentation. The Company’s two segments are North America and International.

The North America segment is comprised of the Company's operations in the United States, Canada and Mexico and the International segment is comprised of geographies outside of North America, which are the Company's operations primarily in Australia, France, Germany, Italy, Malaysia, Spain and Switzerland. Certain expenses incurred at the Company’s headquarters located in the North America segment are allocated to each segment in a manner consistent with where the benefits from the expenses are derived. However, there

-104-

HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

are certain corporate expenses included in the North America segment that we do not allocate. Such expenses include research and development, certain selling, marketing, general, and administrative costs that support the global organization. Sales and transfers between operating segments are accounted for at market-based transaction prices and are eliminated in consolidation. The Company's sales are determined by the country of origin where the sale occurred. For a description of Heska's previous operating segments, refer to Note 17 to the consolidated financial statements included in Part II. Item 8 of Heska's Annual Report on Form 10-K for the year ended December 31, 2019.

Our CODM continues to evaluate segment performance and allocate resources based on Revenue, Cost of Revenue, Gross Profit, Gross Margin and Operating Income. The CODM does not evaluate operating segments using asset information; however, we have included total asset information by segment below as there was a material change in total assets by segment as of December 31, 2020 due to the acquisition of scil.

Lacuna Diagnostics, Inc.

On February 1, 2021 the Company completed the acquisition of Lacuna Diagnostics, Inc. ("Lacuna"), a veterinary digital cytology company, to broaden the Company's point of care diagnostic offering. In exchange for all the outstanding shares of Lacuna, the Company paid total consideration of $4.3 million upon closing. The Company expects to account for this transaction as a business combination however, does not have that accounting complete as of the date of this filing due to the limited time that has passed since the date of transaction.

As additional consideration for the shares, the Company agreed to a contingent earn-out of an additional $2 million based on the achievement of certain performance metrics within a twelve month period ("Initial Earn Out Period"), reducing to $1 million if such metrics were met in a twelve month period subsequent to the Initial Earn Out Period.

Note Receivable

On February 1, 2021, one of our equity investees ("Investee"), for which we account for as a nonmarketable equity security, issued a Promissory Note to the Company (the “Promissory Note”) with a principal amount of $9.0 million and a stated interest rate of 10.0% per annum that is payable monthly. The Promissory Note has a maturity date of December 1, 2024. The Promissory Note provides for interest only payments through December 1, 2023. Beginning on January 1, 2024, the Promissory Note requires repayment of the principal and interest over twelve consecutive monthly payments. Additionally, the Investee issued a warrant to the Company to acquire securities. The warrant expires December 31, 2034. Refer to Note 4 for additional information on our equity investments.

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, 2020.

We acquired scil animal care company GmbH on April 1, 2020 as discussed in Note 3. Acquisition and Related Party Items in Item 8 "Financial Statements and Supplementary Data". The objectives of scil's established internal controls over financial reporting are consistent, in all material respects, with Heska's objectives. Given the significance of the scil acquisition and the complexity of systems and business processes, we have excluded certain acquired scil processes and internal controls from our evaluation of internal control over financial reporting, in accordance with guidance issued by the staff of the US Securities and Exchange Commission. scil accounted for approximately 45% of Heska's total assets at December 31, 2020 and approximately 30% of total net revenue for the fiscal year ended December 31, 2020.

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.

Grant Thornton, 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, 2020.

Changes in Internal Control over Financial Reporting

We evaluated our internal controls over financial reporting in relation to recurring performance, realigned business segments, and changes to the control environment due to COVID-19. Based on the assessment, we determined there was no change in our internal control over financial reporting that occurred during the fourth quarter of 2020 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

EX-4.2

Exhibit 4.2

HESKA CORPORATION

DESCRIPTION OF SECURITIES

DESCRIPTION OF COMMON STOCK

General

The following description summarizes important terms of our common stock. Because it is only a summary, it does not contain all the information that may be important to you. For a complete description of the matters set forth herein, you should refer to our Certificate of Incorporation and our bylaws, both of which are filed as exhibits to our Annual Report on Form 10-K, and to the applicable provisions of Delaware law.

On May 4, 2010, our stockholders approved an amendment to our Certificate of Incorporation (the “NOL Protective Amendment”). The NOL Protective Amendment places restrictions on the transfer of our common stock that could adversely affect our ability to use our domestic Federal Net Operating Loss carryforward (“NOL”). The NOL Protective Amendment reclassified our capital stock into shares of Traditional common stock and common stock, which together we refer to as our “common stock.” These restrictions on transfer prohibit certain future transfers our capital stock that could adversely affect our ability to utilize our NOL and certain income tax credits to reduce our federal income taxes, which we refer to as the “Tax Benefits.” Pursuant to the NOL Protective Amendment, each share of Traditional common stock was automatically reclassified into one share of common stock.

After giving effect to the amendments to our Certificate of Incorporation adopted subsequent to the NOL Protective Amendment, our authorized capital stock consists of 29,000,000 shares of capital stock, par value $0.01 per share, of which:

•13,250,000 shares of original common stock are designated as Traditional common stock;

•13,250,000 shares of NOL restricted common stock are designated as Public common stock; and

•2,500,000 shares are designated as preferred stock.

All outstanding shares of common stock are validly issued, fully paid, and nonassessable.

Voting rights

Each holder of common stock is entitled to one vote for each share of common stock held of record on the applicable record date on all matters submitted to a vote of stockholders. There are no cumulative voting rights for the election of directors in our Certificate of Incorporation. The directors elected at each annual meeting of stockholders shall be elected for a term of office expiring at the next annual meeting of stockholders.

Dividend rights; rights upon liquidation

The holders of common stock are entitled to receive dividends out of assets legally available for dividends at times and in amounts as our board of directors may determine. These dividend rights are subject to any preferential dividend rights that may be granted to holders of outstanding preferred stock.

In the event of our liquidation, dissolution or winding up, each share of common stock is entitled to share pro rata in any distribution of our assets after payment or providing for the payment of liabilities and the liquidation preference of any then outstanding preferred stock.

Preemptive and other rights

Other than as set forth under the caption “Conversion” below, holders of common stock have no preemptive or other rights to purchase, subscribe for or otherwise acquire any unissued or treasury shares or other of our securities. There are no redemption or sinking fund provisions applicable to the common stock securities.

Conversion

Each share of Public common stock will automatically be converted into the equivalent number of shares of Traditional common stock on the earliest of January 1, 2026, the date our board of directors determines that the transfer restrictions described below are no longer necessary or advisable to preserve the Tax Benefits due to changes in tax laws, or the date our board of directors determines in good faith that it is in the best interests of the Company and our stockholders to terminate the transfer restrictions.

NOL transfer restrictions

As a result of the NOL Protective Amendment, the shares of common stock are subject to transfer restrictions such that holders of common stock are restricted from attempting to transfer (which includes any direct or indirect acquisition, sale, transfer, assignment, conveyance, pledge or other disposition) any of the shares of common stock (or options, warrants or other rights to acquire common stock, or securities convertible or exchangeable into common stock), to the extent that such transfer would (i) create or result in an individual or entity becoming a five-percent stockholder of the common stock for purposes of Section 382 of the Internal Revenue Code of 1986, as amended, and the related Treasury Regulations, which individual or entity is referred to as a “five-percent stockholder,” or (ii) increase the stock ownership percentage of any existing five-percent stockholder.

Transfers that violate the provisions of the NOL Protective Amendment shall be null and void ab initio and shall not be effective to transfer any record, legal, beneficial or any other ownership of the number of shares which result in the violation of the NOL Protective Amendment, which shares are referred to as “Excess Securities.” The purported transferee shall not be entitled to any rights as a Company stockholder with respect to the Excess Securities. Instead, the purported transferee would be required, upon demand by us, to transfer the Excess

2

Securities to an agent designated by us for the limited purpose of consummating an orderly arm’s-length sale of such Excess Securities. The net proceeds of the sale will be distributed first to reimburse the agent for any costs associated with the sale, second to the purported transferee to the extent of the price it paid, and finally to the purported transferor to the extent there is any additional amount, or, if the purported transferor cannot readily be identified to us, to cover the costs incurred by us as a result of such prohibited transfer, with the remainder, if any, to be donated to a charity designated by our board of directors.

With respect to any transfer that does not involve a transfer of our “securities” within the meaning of Delaware law but which would cause any five-percent stockholder to violate the transfer restrictions, the following procedure would apply in lieu of those described above. In such case, no such five-percent stockholder would be required to dispose of any interest that is not a security of the Company, but such five-percent stockholder and/or any person whose ownership of our securities is attributed to such five-percent stockholder, would be deemed to have disposed of (and would be required to dispose of) sufficient securities (which securities shall be disposed of in the inverse order in which they were acquired), simultaneously with the transfer, to cause such five-percent stockholder not to be in violation of the transfer restrictions, and such securities would be treated as Excess Securities to be disposed of through the agent under the provisions summarized above, with the maximum amount payable to such five-percent stockholder or such other person that was the direct holder of such Excess Securities from the proceeds of sale by the agent being the fair market value of such Excess Securities at the time of the prohibited transfer.

The NOL Protective Amendment also provides us with various remedies to prevent or respond to a purported transfer that violates its provisions, including that any person who knowingly violates it, together with any persons in the same control group with such person, are jointly and severally liable to us for such amounts as will put us in the same financial position as it would have been in had such violation not occurred.

The foregoing transfer restriction provisions may only be amended or repealed by the affirmative vote of the holders of at least two-thirds of the shares entitled to vote thereon. This summary description of the NOL Protective Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the NOL Protective Amendment.

Anti-takeover provisions in Delaware law and our certificate of incorporation

The NOL Protective Amendment may have an “anti-takeover” effect because, among other things, the common stock restricts the ability of a person, entity or group to accumulate more than five percent of the common stock and the ability of persons, entities or groups now owning more than five percent of the outstanding shares of common stock from acquiring additional shares of common stock without the approval of our board of directors.

We are subject to Section 203 of the Delaware General Corporation Law, an anti-takeover law. In general, the statute prohibits a publicly held Delaware corporation from engaging in a business combination with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the

3

business combination is approved in a prescribed manner. A “business combination” includes a merger, asset sale or other transaction resulting in financial benefit to the stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns (or within three years prior, did own) 15% or more of the corporation’s voting stock.

The Certificate of Incorporation provides that special meetings of stockholders may be called only at the request of our chairman of the board of directors, our chief executive officer or president, or by a resolution adopted by a majority of our board of directors.

The provisions described above, together with the ability of our board of directors to issue preferred stock without stockholder approval, could have the effect of delaying, deferring or preventing a change in control, delaying, deferring or preventing the removal of existing management, deterring potential acquirers from making an offer to our stockholders, and limiting any opportunity of our stockholders to realize premiums over prevailing market prices of our common stock in connection with offers by potential acquirers.

The above-described effects could occur even if a majority of our stockholders might benefit from such a change in control or offer.

Listing

Our common stock is listed on The Nasdaq Capital Market under the symbol “HSKA”.

Section ii.Award Determination. The Committee has the sole discretion in determining whether and to the extent to which the Performance Measures established for the Plan Year have been achieved.

Article III.

PAYMENTS

Section i.Payment to Individual Participants. The Committee will determine any MIP Payout to the CEO. Any individual MIP Payouts to other executive officers will generally be recommended to the Committee by the CEO, although the Committee will make the final determination of any individual MIP Payouts to executive officers of the Company other than the CEO. Any individual MIP Payouts to other non-executive officer Participants will be determined by the CEO.

Section ii.Medium of Payment. In the sole and absolute discretion of the Committee, the MIP Payout may be made in cash, in stock of the Company, in unsecured notes, or in any other alternative forms of compensation.

Section iii.Time of Payment. Unless otherwise determined by the Committee, all MIP Payouts earned shall be paid only after the Committee has reviewed management’s calculations of the achievement of the Performance Measures for the Plan Year and the resulting MIP Payouts. MIP Payouts shall be made by no later than March 15th of the year following the end of any Plan Year.

Section iv.Employment Required. Except in the case of the Participant’s death or as otherwise determined by the Committee or the CEO, as applicable, Participants must remain active employees of Heska or one of its affiliates in a position which qualifies for MIP participation through the end of a given Plan Year in order to be eligible to earn any MIP Payouts.

Section v.Change in Control. If the Company experiences a Change in Control (as defined in the Heska Corporation Stock Incentive Plan or such successor plan as in effect from time to time) during any Plan Year, unless otherwise determined by the Committee, each Participant will receive a MIP Payout equal to such Participant’s Incentive Target, prorated from the beginning of the Plan Year until the date of such Change in Control. Unless otherwise determined by the Committee, MIP Payouts will occur at a time as close as commercially reasonably practicable to the date of the closing of such Change in Control and in all events within 60 days thereafter.

Section vi.Disability. Employees who are on short-term disability will continue to be treated as active employees for purposes of MIP participation. Employees who are on long-term disability will not be treated as active employees for purposes of MIP participation and will not be eligible

for a MIP Payout unless otherwise determined by the Committee. The participation of employees on other personal leave will be considered by the Committee or its designee on a case by case basis.

Article IV.

MISCELLANEOUS

Section i.Parachute Payments. To the extent that any of the payments and benefits provided for under the MIP or any other agreement or arrangement between the Company and a Participant (collectively, the “Payments”) (i) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) and (ii) but for this paragraph would be subject to the excise tax imposed by Section 4999 of the Code, then the Payments shall be payable either (i) in full or (ii) as to such lesser amount which would result in no portion of such Payments being subject to excise tax under Section 4999 of the Code (determined in accordance with the reduction of payments and benefits in the paragraph set forth below); whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999, results in the Participant’s receipt on an after-tax basis of the greatest amount of the Payments, notwithstanding that all or some portion of such Payments may be taxable under Section 4999 of the Code. Except to the extent, if any, otherwise agreed in writing between a Participant and the Company, any determination required under this provision will be made by accountants selected by the Company, whose determination shall be conclusive and binding upon the Participant and the Company for all purposes.

Section ii.No Right to Employment. Nothing in this document is to be construed as a contract of employment of a defined period of time or otherwise altering the status of employee as an at-will employee of the Company. Either party may elect to terminate the employment relationship at any time, without cause or advance notice.

a.Amendment; Termination. The Committee reserves the right to interpret, modify, suspend or terminate this MIP at any time as determined in its sole discretion.

b.Unfunded Plan. No amounts awarded or accrued under this MIP will be funded, set aside or otherwise segregated prior to payment. The obligation to pay the bonuses awarded hereunder will at all times be an unfunded and unsecured obligation of Heska. Participants shall have the status of general creditors and shall look solely to the general assets of Heska for the payment of their bonus awards.

3

c.No Assignment. No Participant will have the right to alienate, assign, encumber, hypothecate or pledge his or her interest in any award under the MIP, voluntarily or involuntarily, and any attempt to so dispose of any such interest will be void. During the lifetime of any Participant, payment of a bonus award under the MIP will only be made to such Participant.

d.Governing Law. This MIP shall be construed in accordance with and governed by the laws of the State of Delaware, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this MIP to the substantive law of another jurisdiction.

EMPLOYMENT AGREEMENT

This Employment Agreement (the "Agreement") is made effective on April 15th, 2020

(the "Effective Date") between Heska Corporation, a Delaware corporation ("Heska"),

and Christopher Sveen ("Executive"). Heska and Executive collectively are referred to as the

RECITALS

WHEREFORE, Executive is currently the Executive Vice President, General Counsel and Chief Administrative Officer, Heska and President, Diamond Animal Health, a wholly- owned subsidiary of Heska.

WHEREFORE, Executive and Heska now wish to enter into this Agreement regarding

the terms of Executive's employment, which shall become effective upon execution.

NOW, THEREFORE, in consideration of the foregoing and of the mutual promises, covenants, and agreements contained herein, the legal sufficiency of which is acknowledged by the Parties, and intending to be legally bound, the Parties agree as follows:

TERMS

1.Duties and Scope of Employment.

a.Position and Duties. As of April 15th, 2020, Executive will serve as Executive Vice President, General Counsel and Chief Administrative Officer, Heska and President, Diamond Animal Health. Executive will render such business and professional services in the performance of Executive's duties, consistent with Executive's position within Heska and/or its subsidiaries, as will reasonably be assigned to

Executive by Heska's Board of Directors, Chief Executive Officer, or Executive's supervisor. Executive's duties will be subject to review and adjustments will be made at the discretion of the Executive's supervisor and superiors.

b.Obligations. During the Term of Agreement (as defined below), Executive will devote Executive's full attention, skills, time and business efforts to Heska and/or its subsidiaries. For the duration of the Term of Agreement, Executive agrees not to actively engage in any other employment, occupation, or consulting activity, for any direct or indirect remuneration, without the prior approval of the Board or the Corporate Governance Committee of the Board; provided, however, that Executive may, without the approval of the Board or the Corporate Governance Committee of the Board, serve in any capacity with any civic, educational, or charitable organization, provided such services do not interfere with Executive's obligations to Heska.

2.Term of Agreement.

a.The period of Executive's employment under this Agreement is referred to herein as the "Term of Agreement." Subject to the provisions for earlier termination of employment in Section 6 below, this Agreement will have an initial term of twelve

(12) months commencing on the Effective Date. On the 1st anniversary of the Effective Date, and on each annual anniversary of the Effective Date thereafter, this Agreement automatically will renew for an additional twelve-month term unless Heska provides Executive with notice of non-renewal at least 120 days prior to the date of automatic renewal; provided, however, that either Heska or Executive may

terminate Executive's employment immediately at any time subject to the provisions

in Section 6 below.

b.Executive may be entitled to severance benefits pursuant to Section 6 below, depending upon the circumstances of Executive's termination of employment. Upon the termination of Executive's employment for any reason, Executive will be entitled to payment of all expense reimbursements, and other benefits due to Executive through Executive's termination date under any Heska-provided or paid plans, policies, and arrangements. Executive agrees to resign from all positions that Executive holds with Heska and its subsidiaries, without limitation, immediately following the termination of Executive's employment if the Board so requests.

1.Compensation.

a.Base Salary. Heska will pay Executive an annual salary of $300,000.00 as compensation for Executive's services (the "Base Salary"). The Base Salary will be paid periodically in accordance with Heska's normal payroll practices and will be subject to the usual, required withholdings and deductions. Executive's salary will be subject to review, and adjustments will be made at the sole discretion of the Compensation Committee of the Board (the "Committee") and based upon Heska's standard practices.

b.Annual Bonus. During the Term of Agreement, Executive will be eligible to

participate in the Management Incentive Plan ("MIP"), a compensation plan intended to reward near term performance (i.e. no longer than the coming year) which may be available from time to time at the discretion of the Committee. MIP Payouts, if any, will accrue and become payable in accordance with the Committee's standard practices for paying executive incentive compensation, provided, however, that any bonus payable under this subsection will be payable within two-and-one-half (2-1/2) months after the end of the taxable year to which it relates or such longer period as may be permitted or required by Treasury regulations in order to avoid application of Section 409A of the Internal Revenue Code of 1986, as amended (the "Code") to such MIP Payouts. Any MIP Payouts paid pursuant to this Section will be subject to applicable withholdings and deductions.

2.Expenses.

a.In addition to the foregoing, Heska will reimburse Executive for Executive's reasonable out-of-pocket travel, entertainment, and other expenses, in accordance with Heska's expense reimbursement policies and practices in effect at the time of the reimbursement request. Executive shall submit such requests within forty-five (45) days of incurring such expenses.

a.During the Term of Agreement, Executive will be eligible to participate in the benefits offered to other executives of Heska, in accordance with benefit plans, policies, and arrangements that may exist from time to time.

2.Termination and Severance.

a.Termination without Cause or for Good Reason other than In Connection with a Change of Control. If, at any time, Executive's employment is terminated by Heska without Cause (as defined below), by Executive for Good Reason (as defined below), or due to Executive's death or Disability (as defined below) or pursuant to Heska's delivery of notice of non-renewal pursuant to Section 2(a) above, and the termination is not In Connection with a Change of Control (as defined below), Executive will receive the following, subject to conditions and limitations set forth in Section 7:

i.A payment of an amount equal to six (6) months of Executive's Base Salary, payable in accordance with Heska's standard payroll practices over the shorter of the following periods (A) in equal installments over the period beginning on the date of such termination and ending on the one-year anniversary thereof, or (B) in equal installments on a monthly basis corresponding to the amount Executive would normally receive as salary each month if Executive were still employed with Heska, with a lump sum of any remaining balance of the amount specified above on March 15 of the year following the year of termination.

ii.Provided that, within thirty (30) days of termination date, Executive elects continuation coverage under the Consolidated Omnibus Budget

Reconciliation Act of 1985, as amended ("COBRA"), Heska shall pay the COBRA premium for coverage for Executive and Executive's eligible dependents under Heska's Benefit Plans (as defined below) for six (6) months, or if earlier, until Executive becomes employed by another employer and

eligible for coverage under such other employer's welfare benefit plans (e.g., payments for medical COBRA premiums will cease when Executive becomes eligible for another employer's medical plan.) For the balance of the period during which Executive and Executive's eligible dependents are entitled to coverage under COBRA, Executive shall be entitled to maintain coverage for Executive and Executive's eligible dependents at Executive's sole expense.

Executive shall notify Heska immediately upon Executive's acceptance of

employment with another employer.

a.Termination without Cause or for Good Reason In Connection with a Change of Control. If, at any time, Executive's employment is terminated by Heska without Cause or by Executive for Good Reason or pursuant to Heska's delivery of notice of non-renewal pursuant to Section 2(a) above, and the termination is In Connection with a Change of Control (as defined below), then, subject to the limitations set forth in this Section 7, Executive will receive:

i.A payment of an amount equal to twelve (12) months of Executive's Base Salary, payable in equal installments in accordance with the standard payroll schedule over the shorter of the following periods (A) the period beginning on the date of such termination and ending on the one-year anniversary thereof, or (B) the period beginning on the date of such termination and ending on March 15 of the year following the year of termination.

ii.Provided that, within thirty (30) days of termination date, Executive elects continuation coverage under COBRA, Heska shall pay the COBRA premium for coverage for Executive and Executive's eligible dependents under Heska's Benefit Plans (as defined below) for twelve (12) months, or if earlier, until Executive becomes employed by another employer and eligible for coverage under such other employer's welfare benefit plans (e.g., payments for medical COBRA premiums will cease when Executive becomes eligible for another employer's medical plan). For the balance of the period during which

Executive and Executive's eligible dependents are entitled to coverage under COBRA, Executive shall be entitled to maintain coverage for Executive and Executive's eligible dependents at Executive's sole expense. Executive shall notify Heska immediately upon Executive's acceptance of employment with another employer.

b.Termination without Good Reason; Termination for Cause. If, at any time, Executive's employment with Heska terminates voluntarily by Executive without Good Reason or is terminated for Cause by Heska, then (i) all further vesting of

Executive's outstanding equity awards will terminate immediately, (ii) all payments of compensation by Heska to Executive hereunder will terminate immediately (except as to amounts already earned), but Executive will be paid all expense

reimbursements, and other benefits due to Executive through Executive's termination date under any Company-provided or paid plans, policies, and arrangements, and (iii) Executive will not be entitled to any severance.

c.Excise Tax. In the event that any benefits payable to Executive pursuant to Section 6 of this Agreement ("Termination Benefits") (i) constitute "parachute payments" within the meaning of Section 280G of the Code, or any comparable successor provisions, and (ii) but for this Section 6(d), would be subject to the excise tax

imposed by Section 4999 of the Code, or any comparable successor provisions (the "Excise Tax"), then Executive's Termination Benefits hereunder shall be either (A) provided to Executive in full, or (B) provided to Executive as to such lesser extent which would result in no portion of such benefits being subject to the Excise Tax, whichever of the foregoing amounts, when taking into account applicable federal, state, local, and foreign income and employment taxes, the Excise Tax, and any other applicable taxes, results in the receipt by Executive, on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under the Excise Tax. Unless Heska and Executive otherwise agree in writing, any determination required under this Section 6(d) shall be made in

writing in good faith by Heska's independent accountants. In the event of a reduction of benefits hereunder, Executive shall be given the choice of which benefits to reduce. If Executive does not provide written identification to Heska of which benefits Executive chooses to reduce within ten (10) days after written notice of the accountants' determination, and Executive has not disputed the accountants' determination, then Heska shall select the benefits to be reduced. For purposes of making the calculations required by this Section 6(d), the accountants may make reasonable assumptions and approximations concerning the applicable taxes and may rely on reasonable, good faith interpretations concerning the application of the Code and other applicable legal authority. Heska and Executive shall furnish to the accountants such information and documents as the accountants may reasonably request in order to make a determination under this Section 6(d). Heska shall bear all costs the accountants may reasonably incur in connection with any calculations contemplated by this Section 6(d).

1.Conditions to Receipt of Severance; No Duty to Mitigate; Covenants.

a.Separation Agreement and Release of Claims. The receipt of any severance pursuant to Section 6 will be subject to Executive signing and not revoking a confidential separation agreement and release of claims in a form reasonably acceptable to Heska. Such agreement will provide (among other things) that Executive will not disparage Heska, its affiliates, parents, subsidiaries, directors, executive officers, employees, agents, or representatives. No severance will be paid or provided until the confidential separation agreement and release agreement becomes effective. No severance will be paid or provided if the Executive's confidential separation agreement and release agreement is not signed and irrevocable within forty-five (45) days after the Executive's termination date. If Executive's date of termination and the last day of any applicable statutory revocation period could fall in two separate taxable years, regardless of when Executive actually executes and delivers the release, payments will not commence until the later taxable year.

b.Non-Competition. In the event of a termination of Executive's employment that would entitle Executive to the receipt of severance pursuant to Sections 6(a) or 6(b), or a termination for Cause by Heska, Executive agrees not to engage in Competition (as defined below) for six (6) months following the termination date. The geographic

scope of this Section 7(b) is the United States of America and Europe. If Executive engages in Competition within such period, all continuing payments and benefits to which Executive otherwise may be entitled pursuant to Section 6 will cease immediately.

a.Non-Solicitation. In the event of a termination of Executive's employment that would entitle Executive to the receipt of severance pursuant to Sections 6(a) or 6(b), or a termination for Cause by Heska, Executive agrees that, for twelve (12) months following the termination date, Executive, directly or indirectly, whether as employee, owner, sole proprietor, partner, director, member, consultant, agent, founder, co-venturer, or otherwise, (i) will not solicit, induce, or influence any person to modify his or her employment or consulting relationship with Heska (the "No-

Inducement"), and (ii) not intentionally divert business away from Heska by soliciting business from any of Heska's customers and users who would otherwise

have placed the solicited order with Heska (the "No Solicit"). The geographic scope of this Section 7(c) is the United States of America and Europe. If Executive breaches the No-Inducement or No Solicit, all continuing payments and benefits to which Executive otherwise may be entitled pursuant to Section 6 will cease immediately.

b.Remedies. In the event of Executive's breach of Sections 7(b) or 7(c), Heska shall have any and all remedies available to it in law or in equity, including without limitation the right to seek recovery of any amounts paid under Section 6 of this Agreement and injunctive relief, specific performance, or any other equitable relief to prevent a breach and to secure the enforcement of this Section. Injunctive relief may be granted immediately upon the commencement of any such action, and Heska need not post a bond to obtain temporary or permanent injunctive relief.

c.No Duty to Mitigate.Executive is under no duty or requirement to mitigate the amount of any payment contemplated by this Agreement, nor will any earnings that Executive may receive from any other source reduce any such payment.

1.Definitions.

immediately prior to Executive's termination of employment provide Executive and Executive's eligible dependents with medical, dental, or vision benefits. Benefit Plans do not include any other type of benefit (including, but not limited to, financial counseling, disability, life insurance, or retirement benefits). A requirement that Heska provide Executive and Executive's eligible dependents with coverage under the Benefit Plans will not be satisfied unless the coverage is no less favorable than

that provided to Executive and Executive's eligible dependents immediately prior to Executive's termination of employment.

a.Cause. For purposes of this Agreement, "Cause" shall mean the occurrence of one or more of the following: (i) conviction of, or an entry of a plea of nolo contendere to, any crime (including one involving moral turpitude), whether a felony or misdemeanor, or any crime which reflects so negatively on Heska to be detrimental to Heska's image or interests, or any act of fraud or dishonesty that has such negative reflection upon Heska; (ii) the repeated commitment of insubordination or refusal to comply with any reasonable request of Heska's Board of Directors, Chief Executive Officer, or Executive's supervisor related to the scope or performance of Executive's duties; (iii) possession of any illegal drug on Heska premises or being under the influence of illegal drugs or abusing prescription drugs or alcohol while on Heska business, attending Heska-sponsored functions, or on Heska premises; (iv) the gross misconduct or gross negligence in the performance of Executive's responsibilities which, based upon good faith and reasonable factual investigation of the Board,

demonstrates Executive's unfitness to serve; (v) material breach of Executive's obligations under this Agreement; or (vi) material breach of any fiduciary duty of Executive to Heska or its subsidiaries,; provided, however, that if any occurrence under subsections (ii), (iv), (v), and (vi) is reasonably capable of being cured, Heska will provide notice to Executive describing the nature of such event and Executive will thereafter have thirty (30) days to cure such event, and if such event is cured within that 30-day period, then grounds will no longer exist for terminating

Executive's employment for Cause; and provided, further, that such cure period will not apply to any subsequent occurrence of the same event.

an authorized officer of any successor company to Heska, directly or indirectly (1) provides services or assistance in any form to any individual, entity, or company providing veterinary products for the companion animal health industry or imaging products or services for the veterinary market (a "Restricted Company"), whether such services or assistance is provided as an employee, consultant, agent, corporate officer, director, or otherwise or (2) participates in the financing, operation, management, or control of, a Restricted Company. A Restricted Company includes, without limitation, Zoetis, Inc. Abaxis, Inc. (currently a wholly-owned subsidiary of Zoetis, Inc.), IDEXX Laboratories, Inc., Sound Technologies, Inc. (currently a unit of Mars, Incorporated), and Zoetis, Inc. Notwithstanding the foregoing, nothing contained in this Section 8(d) or in Section 7(b) above shall prohibit Executive from being employed or engaged in a corporate function or senior management position (and holding commensurate equity interests) in a division of a Restricted Company, so long as such division is not in any way engaged in providing veterinary products for the companion animal health industry or imaging products or services for the veterinary market and Executive does not directly or indirectly provide services or assistance to any division that does provide veterinary products for the companion animal health industry or imaging products or services for the veterinary market.

2.a material diminution in Executive's Base Salary as in effect immediately prior to such diminution; provided, that an across-the- board reduction in the base compensation and benefits of all other executive officers of Heska by the same percentage amount (or under the same terms and conditions) as part of a general base compensation reduction and/or benefit reduction shall not constitute such a qualifying material diminution;

1.a material change in the geographic location of Executive's principal place of employment such that the new location is greater than fifty (50) road miles each way from Executive's place of employment on the Effective Date;

2.any material breach by Heska of any provision of this Agreement; and

3.any acquiring company fails to assume or be bound by the terms of this Agreement in Connection with a Change of Control;

i.The aforementioned occurrences shall not be deemed Good Reason unless Executive gives Heska written notice of the existence of the condition which Executive believes constitutes Good Reason (which notice must be given within ninety (90) days of the initial existence of the condition) and such condition remains uncured for a period of thirty (30) days after the date of such notice. An event of Good Reason shall occur automatically at the expiration of such 30-day period if the relevant condition remains uncured at such time.

a.In Connection with a Change of Control. For purposes of this Agreement, a

termination of Executive's employment with Heska is "In Connection with a Change of Control" if Executive's employment is terminated without Cause or for Good Reason during the period beginning three (3) months prior to a Change of Control and ending eighteen (18) months following a Change of Control.

During the Term of Agreement, and for twenty-four (24) months after termination of Executive's employment, Executive agrees, if requested by Heska, to execute any updated versions of Heska's form of employee confidential information agreement as may be required of substantially all of Heska's executive officers.

ii.one (1) day after being delivered through a nationally recognized overnight courier service, or

2.Successors and Assigns.

a.This Agreement will be binding upon and inure to the benefit of (a) the heirs,

executors, and legal representatives of Executive upon Executive's death and

(b) any successor of Heska. Any such Successor (as defined below) of Heska will be deemed substituted for Heska under the terms of this Agreement for all purposes.

Any other attempted assignment, transfer, conveyance, or other disposition of Executive's right to compensation or other benefits will be null and void.

3.Integration.

a.This Agreement, together with the Confidentiality Agreement, Heska's stock plans, and Executive's stock option and restricted stock agreements, represents the entire agreement and understanding between the Parties as to the subject matter herein and supersedes all prior or contemporaneous agreements whether written or oral, including the Prior Agreement. No waiver, alteration, or modification of any of the provisions of this Agreement will be binding unless in writing that specifically references this Section and is signed by duly authorized representatives of the Parties hereto.

4.Interpretation.

a.Article titles and section headings contained herein are inserted for convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement. The determination of the terms of, and the drafting of, this Agreement has been by mutual agreement after negotiation, with

consideration by and participation of all Parties. Accordingly, the Parties agree that rules relating to the interpretation of contracts against the drafter of any particular clause shall not apply in the case of this Agreement.

1.Waivers.

a.Any term or provision of this Agreement may be waived, or the time for its performance may be extended, by the Party or Parties entitled to the benefit thereof. Any such waiver shall be validly and sufficiently authorized for the purposes of this Agreement if, as to any Party, it is authorized in writing by an authorized representative of such Party. The failure of any Party hereto to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, nor in any way to affect the validity of this Agreement or any part hereof or the right of any Party thereafter to enforce each and every such provision. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach.

2.Severability.

a.If any provision of this Agreement is held illegal, invalid, or unenforceable, such holding shall not affect any other provisions hereof. In the event any provision is held illegal, invalid, or unenforceable, such provision shall be limited so as to give effect to the intent of the Parties to the fullest extent permitted by applicable law. Any claim by Executive against Heska shall not constitute a defense to enforcement by Heska.

Executive's receipt of any benefit hereunder is conditioned on Executive's satisfaction of any applicable withholding or similar obligations that apply to such benefit, and that any cash payment owed to Executive hereunder will be reduced to satisfy any such withholding or similar obligations that may apply thereto.

b.Executive acknowledges that no representative or agent of Heska has provided Executive with any tax advice of any nature, and Executive has consulted with Executive's own legal, tax, and financial advisor(s) as to tax and related matters concerning the compensation to be received under this Agreement.

4.Section 409A.

a.This Agreement is intended to comply with Section 409A of the Code, as amended

("Section 409A") and shall be construed accordingly. It is the intention of the parties

that payments or benefits payable under this Agreement not be subject to the additional tax or interest imposed pursuant to Section 409A. To the extent such potential payments or benefits are or could become subject to Section 409A, the parties shall cooperate to amend this Agreement with the goal of giving Executive the economic benefits described herein in a manner that does not result in such tax or interest being imposed; provided, however, that no such amendment shall materially increase the cost to, or impose any liability on Heska with respect to any benefits contemplated or provided hereunder. Executive shall, at the request of Heska, take any reasonable action (or refrain from taking any action), required to comply with any correction procedure promulgated pursuant to Section 409A.

a.If a payment that could be made under this Agreement would be subject to additional taxes and interest under Section 409A, Heska in its sole discretion may accelerate some or all of a payment otherwise payable under the Agreement to the time at which such amount is includible in the income of Executive, provided that such acceleration shall only be permitted to the extent permitted under Treasury Regulation § 1.409A- 3(j)(4)(vii) and the amount of such acceleration does not exceed the amount permitted under Treasury Regulation § 1.409A-3(j)(vii).

b.No payment to be made under this Agreement shall be made at a time earlier than that provided for in this Agreement unless such payment is (i) an acceleration of payment permitted to be made under Treasury Regulation § 1.409A-3(j)(4) or (ii) a payment that would otherwise not be subject to additional taxes and interest under Section 409A.

c.The right to each payment described in this Agreement shall be treated as a right to a series of separate payments and a separately identifiable payment for purposes of Section 409A.

d.For purposes of Section 6 of this Agreement, "termination" (or any similar term) when used in reference to Executive's employment shall mean "separation from service" with Heska within the meaning of Section 409A(a)(2)(A)(i) of the Code and applicable administrative guidance issued thereunder, and Executive shall be considered to have terminated employment with Heska when, and only when,

Executive incurs a "separation from service" with Heska within the meaning of Section 409A(a)(2)(A)(i) of the Code and applicable administrative guidance issued thereunder.

e.If Executive qualifies as a "specified employee" within the meaning of Section

409A(a)(2)(B)(i) of the Code and would receive any payment sooner than six

(6) months after Executive's separation from service that, absent the application of this Section 19(f), would be subject to additional tax imposed pursuant to Section 409A as a result of such status as a specified employee, then such payment shall instead be payable on the date that is the earliest of (i) six (6) months after

Executive's separation from service, (ii) Executive's death, or (iii) such other date as will not result in such payment being subject to such additional tax.

1.Governing Law; Waiver of Jury Trial.

a.This Agreement shall be governed by and construed in accordance with the internal laws of the State of Colorado without regard to conflict of law principles. The Parties hereto each waive their respective rights to a jury trial of any and all such claims and causes of action.

2.Counterparts.

a.This Agreement may be executed in counterparts, and each counterpart will have the same force and effect as an original and will constitute an effective, binding agreement on the part of each of the undersigned.

RECITALS

WHEREFORE, Executive is currently the Executive Vice President, Managing Director and Chief Operating Officer, scil animal care company, a wholly-owned subsidiary of Heska.

WHEREFORE, Executive and Heska now wish to enter into this Agreement regarding the terms of Executive’s employment, which shall become effective upon execution.

TERMS

1. Duties and Scope of Employment.

a.Position and Duties. As of April 9th, 2020, Executive will serve as Executive Vice President, Managing Director and Chief Operating Officer, scil animal care company.

Executive’s duties will be subject to review and adjustments will be made at the discretion of the Executive’s supervisor and superiors.

b.Obligations. During the Term of Agreement (as defined below), Executive will devote Executive’s full attention, skills, time and business efforts to Heska and/or its subsidiaries. For the duration of the Term of Agreement, Executive agrees not to actively engage in any other employment, occupation, or consulting activity, for any direct or indirect remuneration, without the prior approval of the Board or the Corporate Governance Committee of the Board; provided, however, that Executive may, without the approval of the Board or the Corporate Governance Committee of the Board, serve in any capacity with any civic, educational, or charitable organization, provided such services do not interfere with Executive’s obligations to Heska.

2.    Term of Agreement.

a.The period of Executive’s employment under this Agreement is referred to herein as the “Term of Agreement.” Subject to the provisions for earlier termination of employment in Section 6 below, this Agreement will have an initial term of twelve (12) months commencing on the Effective Date. On the 1st anniversary of the Effective Date, and on each annual anniversary of the Effective Date thereafter, this Agreement automatically will renew for an additional twelve-month term unless Heska provides Executive with notice of non-renewal at least 120 days prior to the date of automatic renewal; provided, however, that either Heska or Executive may terminate Executive’s employment immediately at any time subject to the provisions in Section 6 below.

b.Executive may be entitled to severance benefits pursuant to Section 6 below, depending upon the circumstances of Executive’s termination of employment. Upon the termination of Executive’s employment for any reason, Executive will be entitled to payment of all expense reimbursements, and other benefits due to Executive through Executive’s termination date under any Heska-provided or paid plans, policies, and arrangements.

ii.Provided that, within thirty (30) days of termination date, Executive elects continuation coverage under COBRA, Heska shall pay the COBRA premium for coverage for Executive and Executive’s eligible dependents under Heska’s Benefit Plans (as defined below) for twelve (12) months, or if earlier, until Executive becomes employed by another employer and eligible for coverage under such other employer’s welfare benefit plans (e.g., payments for medical COBRA premiums will cease when Executive becomes eligible for another employer’s medical plan). For the balance of the period during which Executive and Executive’s eligible dependents are entitled to coverage under COBRA, Executive shall be entitled to maintain coverage for Executive and Executive’s eligible dependents at Executive’s sole expense. Executive shall notify Heska immediately upon Executive’s acceptance of employment with another employer.

iii.If Executive’s principal place of employment is outside the United States on the termination date, Heska will pay or reimburse the reasonable out-of-pocket costs of Executive’s relocation to the United States, if Executive so elects within thirty (30) days of the termination date.

c.Termination without Good Reason; Termination for Cause.  If, at any time, Executive’s employment with Heska terminates voluntarily by Executive without Good Reason or is terminated for Cause by Heska, then (i) all further vesting of Executive’s outstanding equity awards will terminate immediately, (ii) all payments

of compensation by Heska to Executive hereunder will terminate immediately (except as to amounts already earned), but Executive will be paid all expense reimbursements, and other benefits due to Executive through Executive’s termination date under any Company-provided or paid plans, policies, and arrangements, and (iii) Executive will not be entitled to any severance.

d.Excise Tax.  In the event that any benefits payable to Executive pursuant to Section 6 of this Agreement (“Termination Benefits”) (i) constitute “parachute payments” within the meaning of Section 280G of the Code, or any comparable successor provisions, and (ii) but for this Section 6(d), would be subject to the excise tax imposed by Section 4999 of the Code, or any comparable successor provisions (the “Excise Tax”), then Executive’s Termination Benefits hereunder shall be either (A) provided to Executive in full, or (B) provided to Executive as to such lesser extent which would result in no portion of such benefits being subject to the Excise Tax, whichever of the foregoing amounts, when taking into account applicable federal, state, local, and foreign income and employment taxes, the Excise Tax, and any other applicable taxes, results in the receipt by Executive, on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under the Excise Tax. Unless Heska and Executive otherwise agree in writing, any determination required under this Section 6(d) shall be made in writing in good faith by Heska’s independent accountants. In the event of a reduction of benefits hereunder, Executive shall be given the choice of which benefits to reduce. If Executive does not provide written identification to Heska of which benefits Executive chooses to reduce within ten (10) days after written notice of the accountants’ determination, and Executive has not disputed the accountants’ determination, then Heska shall select the benefits to be reduced. For purposes of making the calculations required by this Section 6(d), the accountants may make reasonable assumptions and approximations concerning the applicable taxes and may rely on reasonable, good faith interpretations concerning the application of the Code and other applicable legal authority. Heska and Executive shall furnish to the accountants such information and documents as the accountants may reasonably request in order to make a determination under this Section 6(d). Heska shall bear all costs the accountants may reasonably incur in connection with any calculations contemplated by this Section 6(d).

7. Conditions to Receipt of Severance; No Duty to Mitigate; Covenants.

a.Separation Agreement and Release of Claims.  The receipt of any severance pursuant to Section 6 will be subject to Executive signing and not revoking a confidential separation agreement and release of claims in a form reasonably acceptable to Heska. Such agreement will provide (among other things) that Executive will not disparage Heska, its affiliates, parents, subsidiaries, directors, executive officers, employees, agents, or representatives. No severance will be paid or provided until the confidential separation agreement and release agreement

becomes effective. No severance will be paid or provided if the Executive’s confidential separation agreement and release agreement is not signed and irrevocable within forty-five (45) days after the Executive’s termination date. If Executive's date of termination and the last day of any applicable statutory revocation period could fall in two separate taxable years, regardless of when Executive actually executes and delivers the release, payments will not commence until the later taxable year.

b.Non-Competition.  In the event of a termination of Executive’s employment that would entitle Executive to the receipt of severance pursuant to Sections 6(a) or 6(b), or a termination for Cause by Heska, Executive agrees not to engage in Competition (as defined below) for six (6) months following the termination date. The geographic scope of this Section 7(b) is the United States of America and Europe. If Executive engages in Competition within such period, all continuing payments and benefits to which Executive otherwise may be entitled pursuant to Section 6 will cease immediately.

c.Non-Solicitation.  In the event of a termination of Executive’s employment that would entitle Executive to the receipt of severance pursuant to Sections 6(a) or 6(b), or a termination for Cause by Heska, Executive agrees that, for twelve (12) months following the termination date, Executive, directly or indirectly, whether as employee, owner, sole proprietor, partner, director, member, consultant, agent, founder, co-venturer, or otherwise, (i) will not solicit, induce, or influence any person to modify his or her employment or consulting relationship with Heska (the “No-Inducement”), and (ii) not intentionally divert business away from Heska by soliciting business from any of Heska’s customers and users who would otherwise have placed the solicited order with Heska (the “No Solicit”). The geographic scope of this Section 7(c) is the United States of America and Europe. If Executive breaches the No-Inducement or No Solicit, all continuing payments and benefits to which Executive otherwise may be entitled pursuant to Section 6 will cease immediately.

d.Remedies.  In the event of Executive’s breach of Sections 7(b) or 7(c), Heska shall have any and all remedies available to it in law or in equity, including without limitation the right to seek recovery of any amounts paid under Section 6 of this Agreement and injunctive relief, specific performance, or any other equitable relief to prevent a breach and to secure the enforcement of this Section. Injunctive relief may be granted immediately upon the commencement of any such action, and Heska need not post a bond to obtain temporary or permanent injunctive relief.

e.No Duty to Mitigate. Executive is under no duty or requirement to mitigate the amount of any payment contemplated by this Agreement, nor will any earnings that Executive may receive from any other source reduce any such payment.

8.    Definitions.

a.Benefit Plans.  For purposes of this Agreement, “Benefit Plans” means plans, policies, or arrangements that Heska sponsors (or participates in) and that immediately prior to Executive’s termination of employment provide Executive and Executive’s eligible dependents with medical, dental, or vision benefits. Benefit Plans do not include any other type of benefit (including, but not limited to, financial counseling, disability, life insurance, or retirement benefits). A requirement that Heska provide Executive and Executive’s eligible dependents with coverage under the Benefit Plans will not be satisfied unless the coverage is no less favorable than that provided to Executive and Executive’s eligible dependents immediately prior to Executive’s termination of employment.

b.Cause.  For purposes of this Agreement, “Cause” shall mean the occurrence of one or more of the following: (i) conviction of, or an entry of a plea of nolo contendere to, any crime (including one involving moral turpitude), whether a felony or misdemeanor, or any crime which reflects so negatively on Heska to be detrimental to Heska’s image or interests, or any act of fraud or dishonesty that has such negative reflection upon Heska; (ii) the repeated commitment of insubordination or refusal to comply with any reasonable request of Heska’s Board of Directors, Chief Executive Officer, or Executive’s supervisor related to the scope or performance of Executive’s duties; (iii) possession of any illegal drug on Heska premises or being under the influence of illegal drugs or abusing prescription drugs or alcohol while on Heska business, attending Heska-sponsored functions, or on Heska premises; (iv) the gross misconduct or gross negligence in the performance of Executive’s responsibilities which, based upon good faith and reasonable factual investigation of the Board, demonstrates Executive’s unfitness to serve; (v) material breach of Executive’s obligations under this Agreement; or (vi) material breach of any fiduciary duty of Executive to Heska or its subsidiaries,; provided, however, that if any occurrence under subsections (ii), (iv), (v), and (vi) is reasonably capable of being cured, Heska will provide notice to Executive describing the nature of such event and Executive will thereafter have thirty (30) days to cure such event, and if such event is cured within that 30-day period, then grounds will no longer exist for terminating Executive’s employment for Cause; and provided, further, that such cure period will not apply to any subsequent occurrence of the same event.

c.Change of Control.  For purposes of this Agreement, “Change of Control” means (i) a sale of all or substantially all of Heska’s assets, (ii) any merger, consolidation, or other business combination transaction of Heska with or into another corporation, entity, or person, other than a transaction in which the holders of at least a majority of the shares of voting capital stock of Heska outstanding immediately prior to such transaction continue to hold (either by such shares remaining outstanding or by their being converted into shares of voting capital stock of the surviving entity) a majority of the total voting power represented by the shares of voting capital stock of Heska (or the surviving entity) outstanding immediately after such transaction, (iii) the direct or indirect acquisition (including by way of a tender or exchange offer) by any

person, or persons acting as a group, of beneficial ownership or a right to acquire beneficial ownership of shares representing a majorityof the voting power of the then outstanding shares of capital stock of Heska, (iv) a contested election of Directors, as a result of which or in connection with which the persons who were Directors before such election or their nominees cease to constitute a majority of the Board, or (v) a dissolution or liquidation of Heska.

d.Competition.  For purposes of this Agreement, Executive will be deemed to have engaged in “Competition” if Executive, without the written consent of the Board or an authorized officer of any successor company to Heska, directly or indirectly (1) provides services or assistance in any form to any individual, entity, or company providing veterinary products for the companion animal health industry or imaging products or services for the veterinary market (a “Restricted Company”), whether such services or assistance is provided as an employee, consultant, agent, corporate officer, director, or otherwise or (2) participates in the financing, operation, management, or control of, a Restricted Company. A Restricted Company includes, without limitation, Zoetis, Inc. Abaxis, Inc. (currently a wholly-owned subsidiary of Zoetis, Inc.), IDEXX Laboratories, Inc., Sound Technologies, Inc. (currently a unit of Mars, Incorporated), and Zoetis, Inc. Notwithstanding the foregoing, nothing contained in this Section 8(d) or in Section 7(b) above shall prohibit Executive from being employed or engaged in a corporate function or senior management position (and holding commensurate equity interests) in a division of a Restricted Company, so long as such division is not in any way engaged in providing veterinary products for the companion animal health industry or imaging products or services for the veterinary market and Executive does not directly or indirectly provide services or assistance to any division that does provide veterinary products for the companion animal health industry or imaging products or services for the veterinary market.

e.Disability.  For purposes of this Agreement, “Disability” shall mean that, by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, the Executive either (i) is unable to engage in any gainful activity, or (ii) is receiving income replacement benefits for a period of not less than three (3) months under an accident and health plan covering Heska employees.

f.Good Reason.

i.For purposes of this Agreement, “Good Reason” means the occurrence of any of the following without Executive’s express written consent:

1.Executive’s officer level with Heska is, or Executive’s duties or responsibilities are, materially diminished relative to Executive’s officer level, duties, and responsibilities as in effect immediately prior to such change;

2.a material diminution in Executive’s Base Salary as in effect immediately prior to such diminution; provided, that an across-the-board reduction in the base compensation and benefits of all other executive officers of Heska by the same percentage amount (or under the same terms and conditions) as part of a general base compensation reduction and/or benefit reduction shall not constitute such a qualifying material diminution;

3.a material change in the geographic location of Executive's principal place of employment such that the new location is greater than fifty (50) road miles each way from Executive's place of employment on the Effective Date;

4.any material breach by Heska of any provision of this Agreement; and

5.any acquiring company fails to assume or be bound by the terms of this Agreement In Connection with a Change of Control;

ii.The aforementioned occurrences shall not be deemed Good Reason unless Executive gives Heska written notice of the existence of the condition which Executive believes constitutes Good Reason (which notice must be given within ninety (90) days of the initial existence of the condition) and such condition remains uncured for a period of thirty (30) days after the date of such notice. An event of Good Reason shall occur automatically at the expiration of such 30-day period if the relevant condition remains uncured at such time.

g.In Connection with a Change of Control. For purposes of this Agreement, a termination of Executive’s employment with Heska is “In Connection with a Change of Control” if Executive’s employment is terminated without Cause or for Good Reason during the period beginning three (3) months prior to a Change of Control and ending eighteen (18) months following a Change of Control.

9.    Confidential Information.

a.Executive acknowledges that Executive has executed Heska’s standard employee Confidential Information and Invention Agreement (the “Confidentiality Agreement”). During the Term of Agreement, and for twenty-four (24) months after termination of Executive’s employment, Executive agrees, if requested by Heska, to execute any updated versions of Heska’s form of employee confidential information agreement as may be required of substantially all of Heska’s executive officers.

10.    Executive’s Representations and Warranties. 

a.Executive represents and warrants that Executive is not a party to any other employment, non-competition, or other agreement or restriction which could interfere with the Executive’s employment with Heska or Executive’s or Heska’s rights and

obligations hereunder and that Executive’s acceptance of employment with Heska and the performance of Executive’s duties hereunder will not breach the provisions of any contract, agreement, or understanding to which the Executive is party or any duty owed by the Executive to any other person.

11.    Notices.

a.All notices, requests, demands, and other communications called for hereunder will be in writing and will be deemed given:

i.on the date of delivery if delivered personally,

ii.one (1) day after being delivered through a nationally recognized overnight courier service, or

iii.five (5) business days after the date of mailing if sent certified or registered mail.

iv.Notice to Heska shall be sent to its principal place of business with a copy provided by facsimile or electronic communication to the Chair of the Board of Directors, and notice to Executive will be delivered personally or sent to Executive’s last known address provided to Heska.

12.    Successors and Assigns.

a.This Agreement will be binding upon and inure to the benefit of (a) the heirs, executors, and legal representatives of Executive upon Executive’s death and 

(b) any successor of Heska. Any such Successor (as defined below) of Heska will be deemed substituted for Heska under the terms of this Agreement for all purposes. For purposes of this Section, “Successor” means any person, firm, corporation, or other business entity which at any time, whether by purchase, merger, or otherwise, directly or indirectly, acquires all or substantially all of the assets or business of Heska. None of the rights of Executive to receive any form of compensation payable pursuant to this Agreement may be assigned or transferred except by will or the laws of descent and distribution. Any other attempted assignment, transfer, conveyance, or other disposition of Executive’s right to compensation or other benefits will be null and void.

13.    Integration.

a.This Agreement, together with the Confidentiality Agreement, Heska’s stock plans, and Executive’s stock option and restricted stock agreements, represents the entire agreement and understanding between the Parties as to the subject matter herein and supersedes all prior or contemporaneous agreements whether written or oral, including the Prior Agreement. No waiver, alteration, or modification of any of the provisions of this Agreement will be binding unless in writing that specifically references this Section and is signed by duly authorized representatives of the Parties hereto.

14.    Interpretation.

a.Article titles and section headings contained herein are inserted for convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement. The determination of the terms of, and the drafting of, this Agreement has been by mutual agreement after negotiation, with

consideration by and participation of all Parties. Accordingly, the Parties agree that rules relating to the interpretation of contracts against the drafter of any particular clause shall not apply in the case of this Agreement.

15.    Waivers.

a.Any term or provision of this Agreement may be waived, or the time for its performance may be extended, by the Party or Parties entitled to the benefit thereof. Any such waiver shall be validly and sufficiently authorized for the purposes of this Agreement if, as to any Party, it is authorized in writing by an authorized representative of such Party. The failure of any Party hereto to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, nor in any way to affect the validity of this Agreement or any part hereof or the right of any Party thereafter to enforce each and every such provision. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach.

16.    Severability.

a.If any provision of this Agreement is held illegal, invalid, or unenforceable, such holding shall not affect any other provisions hereof. In the event any provision is held illegal, invalid, or unenforceable, such provision shall be limited so as to give effect to the intent of the Parties to the fullest extent permitted by applicable law. Any claim by Executive against Heska shall not constitute a defense to enforcement by Heska.

17.    Tax Matters.

a.Except as provided in Section 6(d) above, Executive agrees that Executive is responsible for any applicable taxes of any nature (including any penalties or interest that may apply to such taxes) that are reasonably determined to apply to any payment made to Executive hereunder (or any arrangement contemplated hereunder), that Executive’s receipt of any benefit hereunder is conditioned on Executive’s satisfaction of any applicable withholding or similar obligations that apply to such benefit, and that any cash payment owed to Executive hereunder will be reduced to satisfy any such withholding or similar obligations that may apply thereto.

b.Executive acknowledges that no representative or agent of Heska has provided Executive with any tax advice of any nature, and Executive has consulted with Executive’s own legal, tax, and financial advisor(s) as to tax and related matters concerning the compensation to be received under this Agreement.

18.    Section 409A.

a.This Agreement is intended to comply with Section 409A of the Code, as amended (“Section 409A”) and shall be construed accordingly. It is the intention of the parties that payments or benefits payable under this Agreement not be subject to the additional tax or interest imposed pursuant to Section 409A. To the extent such potential payments or benefits are or could become subject to Section 409A, the

parties shall cooperate to amend this Agreement with the goal of giving Executive the economic benefits described herein in a manner that does not result in such tax or interest being imposed; provided, however, that no such amendment shall materially increase the cost to, or impose any liability on Heska with respect to any benefits contemplated or provided hereunder. Executive shall, at the request of Heska, take any reasonable action (or refrain from taking any action), required to comply with any correction procedure promulgated pursuant to Section 409A.

b.If a payment that could be made under this Agreement would be subject to additional taxes and interest under Section 409A, Heska in its sole discretion may accelerate some or all of a payment otherwise payable under the Agreement to the time at which such amount is includible in the income of Executive, provided that such acceleration shall only be permitted to the extent permitted under Treasury Regulation § 1.409A-3(j)(4)(vii) and the amount of such acceleration does not exceed the amount permitted under Treasury Regulation § 1.409A-3(j)(vii).

c.No payment to be made under this Agreement shall be made at a time earlier than that provided for in this Agreement unless such payment is (i) an acceleration of payment permitted to be made under Treasury Regulation § 1.409A-3(j)(4) or (ii) a payment that would otherwise not be subject to additional taxes and interest under Section 409A.

d.The right to each payment described in this Agreement shall be treated as a right to a series of separate payments and a separately identifiable payment for purposes of Section 409A.

e.For purposes of Section 6 of this Agreement, “termination” (or any similar term) when used in reference to Executive’s employment shall mean “separation from service” with Heska within the meaning of Section 409A(a)(2)(A)(i) of the Code and applicable administrative guidance issued thereunder, and Executive shall be considered to have terminated employment with Heska when, and only when, Executive incurs a “separation from service” with Heska within the meaning of Section 409A(a)(2)(A)(i) of the Code and applicable administrative guidance issued thereunder.

f.If Executive qualifies as a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code and would receive any payment sooner than six (6) months after Executive’s separation from service that, absent the application of this Section 19(f), would be subject to additional tax imposed pursuant to Section 409A as a result of such status as a specified employee, then such payment shall instead be payable on the date that is the earliest of (i) six (6) months after Executive’s separation from service, (ii)  Executive’s death, or (iii) such other date as will not result in such payment being subject to such additional tax.

19.    Governing Law; Waiver of Jury Trial.

a.This Agreement shall be governed by and construed in accordance with the internal laws of the State of Colorado without regard to conflict of law principles. The Parties hereto each waive their respective rights to a jury trial of any and all such claims and causes of action.

20.    Counterparts.

a.This Agreement may be executed in counterparts, and each counterpart will have the same force and effect as an original and will constitute an effective, binding agreement on the part of each of the undersigned.

OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Accounting Policies [Abstract]

OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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 diagnostic laboratory instruments and supplies; digital imaging diagnostic products, software and services; digital cytology 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

In the opinion of management, the accompanying Consolidated Financial Statements contain all adjustments, consisting of normal, recurring adjustments, necessary to present fairly the financial position of the Company as of December 31, 2020 and 2019, as well as the results of our operations, statements of stockholders' equity and cash flows for the twelve months ended December 31, 2020, 2019 and 2018.

The audited Consolidated Financial Statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Our audited 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 loss attributable to non-controlling interest" on our Consolidated Statements of (Loss) Income. Our audited Consolidated Financial Statements are stated in U.S. Dollars and have been prepared in accordance with accounting principles generally accepted in the U.S. ("GAAP").

Beginning in the first quarter of 2020, to limit the spread of COVID-19, governments took various actions including the issuance of stay-at-home policies and social distancing procedures and guidelines, causing some businesses to adjust, reduce or suspend business and operating activities. Veterinary care is widely recognized as an "essential" service for pet owners, and veterinarians continued to deliver essential medical care for sick and injured pets. The stay-at-home policies deployed early in 2020 to combat the spread of COVID-19 resulted in a decrease in companion animal clinical visits, including delay of elective procedures and wellness visits and as a result lowers demand for diagnostic testing services. Beginning in the second quarter of 2020, certain local, state and federal governments began to ease the stay-at-home policies and allowed more businesses and facilities to re-open, leading to a recovery in companion animal clinical visits and associated demand for our diagnostic products. The extent to which the continuation, or a possible second-wave outbreak of COVID-19, or an outbreak of other health epidemics could impact our business, results of operations and financial condition, including the potential for write-offs or impairments of assets and suspension of capital investments, will depend on future developments. We are unable to predict with certainty the effects of the COVID-19 pandemic on our customers, suppliers and vendors, as well as the actions of governments, and when and to what extent normal economic and operating conditions can resume; these effects may differ from those assumed in our projected estimates. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business as a result of any economic impact that has occurred or may occur in the future.

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 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 net realizable value of inventory; determining future costs associated with warranties provided; 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 and investments for estimated useful lives and impairment; estimating the useful lives and standalone selling prices of instruments under leasing arrangements; determining the allocation of purchase price under purchase accounting; estimating the expense associated with the granting of stock; determining the need for, and the amount of a valuation allowance on deferred tax assets; determining the fair value of our embedded derivative; and determining the fair value of the liability component associated with the issuance of convertible debt. Our actual results may differ from these estimates and there may be changes to those estimates in future periods.

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 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.

Covetrus represented 9% and 19% of our consolidated accounts receivable at December 31, 2020 and 2019, respectively. No other customer accounted for more than 10% of our consolidated accounts receivable at December 31, 2020 or 2019.

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

Accounts Receivable and Allowance for Credit Losses

Accounts receivable are recorded net of an allowance for credit losses. From time to time, our customers are unable to meet their payment obligations. We continuously monitor our customers' credit worthiness and establish allowances for estimated credit losses related to our accounts receivable, net investment in leases, contract assets, and promissory notes. Our allowances are established based on factors surrounding the credit risk of specific customers, historical experience including collections and write-off history, and current economic conditions. Account balances are considered past due if payments have not been received within agreed upon invoice and/or contract terms and the Company may employ collection agencies and legal counsel to pursue recovery of defaulted amounts. Account balances are written off against the allowance after all collection efforts have been exhausted and it is probable the receivable will not be recovered. The Company also performs a qualitative assessment, on a quarterly basis, to monitor economic factors and other uncertainties that may require additional adjustments for the expected credit loss allowance. 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. The Company will continue to actively monitor the impact of the COVID-19 pandemic on expected credit losses. In 2020, the Company adopted Accounting

Standards Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326). See "Adoption of New Accounting Standards" below for impacts of adoption.

Changes in the allowance for credit losses are summarized as follows (in thousands):

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 foreign cash accounts at the spot market foreign exchange rate as of each balance sheet date, with changes due to foreign exchange fluctuations recorded in Accumulated other comprehensive income in the Consolidated Balance Sheets. The majority of our cash and cash equivalents are held in accounts not insured by governmental entities. The foreign cash balances are summarized as follows (denominated in foreign currency, in thousands):

	As of December 31,
	2020	2019
European Union Euros	8,520	1,773
Swiss Francs	138	124

Fair Value of Financial Instruments

In accordance with ASC 820, Fair Value Measurements (“ASC 820”), the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Quoted prices in active markets for similar assets and liabilities, quoted prices for identically similar assets or liabilities in markets that are not active and models for which all significant inputs are observable either directly or indirectly.

Level 3: Unobservable inputs reflecting the reporting entity’s own assumptions or external inputs for inactive markets.

The Company's financial instruments consist of cash and cash equivalents, short-term trade receivables and payables, a long-term note receivable with an embedded derivative asset, and its 3.75% Convertible Senior Notes due 2026 (the "Notes"). 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 estimated fair value of the Notes disclosed at each reporting period is evaluated through Level 2 inputs with consideration of quoted market prices in less active markets. For additional information regarding the Company's accounting treatment for the issuance of the Notes, including the fair value measurement of the liability component, refer to Note 16. Convertible Notes.

The Company determined the redemption features of its convertible note receivable represents an embedded derivative. The estimated fair value of the embedded derivative asset is evaluated through Level 3 inputs. The carrying amount of the derivative is recorded at fair value at issuance and will be remeasured each reporting period, with the mark-to-market adjustments to be included in other expense (income). For additional information regarding the Company's accounting treatment for the convertible note receivable, including the fair value measurement of the embedded derivative, refer to Note 17. Convertible Note Receivable.

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 (Loss) 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 43 years
Machinery and equipment	2 to 10 years
Office furniture and equipment	3 to 7 years
Computer hardware and software	3 to 7 years
Leasehold and building improvements	5 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 seven 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.

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. We write down the carrying value of inventory for estimated obsolescence by an amount equal to the difference between the cost of inventory and the estimated market value when warranted based on assumptions of future demand, market conditions, remaining shelf life, or product functionality.

Investments in Unconsolidated Affiliates

Investments in unconsolidated affiliates are measured and recorded as either non-marketable equity securities or equity method investments. Non-marketable equity securities are equity securities without readily determinable fair value that are measured and recorded using a measurement alternative which measures the securities at cost minus impairment, if any, plus or minus changes from qualifying observable price changes. Equity method investments are equity securities in investees we do not control but over which we have the ability to exercise significant influence. When the equity method of accounting is determined to be appropriate, the initial measurement of the investment includes the cost of the investment and all direct transaction costs incurred to acquire the investment. Equity method investments are measured at cost minus impairment, if any, plus or minus our share of equity method investee income or loss, which is recorded as a separate line on the income statement. Both types of investments are evaluated for impairment if a triggering event occurs.

Goodwill, Intangible and Other Long-Lived Assets

Goodwill is initially valued based on the excess of the purchase price of a business combination over the fair value of acquired net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Intangible assets other than goodwill are initially valued at fair value. If a quoted price in an active market for the identical asset is not readily available at the measurement date, the fair value of the intangible asset is estimated based on discounted cash flows using market participant assumptions, which are assumptions that are not specific to the Company. The selection of appropriate valuation methodologies and the estimation of discounted cash flows require significant assumptions about the timing and amounts of future cash flows, risks, appropriate discount rates, and the useful lives of intangible assets. When material, we utilize independent valuation experts to advise and assist us in determining the fair values of the identified intangible assets acquired in connection with a business acquisition and in determining appropriate amortization methods and periods for those intangible 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 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 it is 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. Following the acquisition of scil in April 2020, we restructured our operating segments based on how the Chief Operating Decision Maker (“CODM”) manages the business, allocates resources, makes operating decisions and evaluates operating performance. As further discussed in Note 18, our new reporting segments are North America and International. As a result of the change in operating segments, we also revised our reporting units to aggregate our legal entities based on similarities in economic characteristics. Our new reporting units consist of the following: (1) Heska Corporation and Heska Canada, (2) Diamond Animal Health, (3) scil animal care company GmbH, Optomed, CVM, and Heska Australia, and (4) Heska AG.

As a result of the recent global economic disruption and uncertainty due to the COVID-19 pandemic, the

Company performed a qualitative assessment during the first quarter of 2020. Based on the interim assessment performed, we concluded that there was no triggering event and additionally, no indications of impairment existed. We performed qualitative assessments in the fourth quarters of 2020, 2019, and 2018 and determined that no indications of impairment existed.

We assess the realizability of intangible assets other than goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If an impairment review is triggered, we evaluate the carrying value of intangible assets based on estimated undiscounted future cash flows over the remaining useful life of the primary asset of the asset group and compare that value to the carrying value of the asset group. The cash flows that are used contain our best estimates, using appropriate and customary assumptions and projections at the time. If the net carrying value of an intangible asset exceeds the related estimated undiscounted future cash flows, an impairment to adjust the intangible asset to its fair value would be reported as a non-cash charge to earnings. If necessary, we would calculate the fair value of an intangible asset using the present value of the estimated future cash flows to be generated by the intangible asset, and applying a risk-adjusted discount rate. We had no impairments of our intangible assets during the years ended December 31, 2020, 2019, and 2018.

Revenue Recognition

We generate revenue through the sale of products, either by outright purchase by our customers or through a subscription agreement whereby our customers receive instruments and pay us a monthly fee for the consumables needed to conduct testing. Subscription placement is the majority of our Point of Care laboratory transactions while outright sales to customers are the majority of both Point of Care imaging diagnostic transactions and the sale of pharmaceuticals and vaccines.

For outright sales of products, revenue is recognized when control of the promised product or service is transferred to our customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those products or services (the transaction price). Taxes assessed by governmental authorities and collected from the customer are excluded from our revenue recognition. A performance obligation is a promise in a contract to transfer a distinct product or service to a customer and is the unit of account under ASC 606. For instruments, consumables and most software licenses sold by the Company, control transfers to the customer at a point in time. To indicate the transfer of control, the Company must have a present right to payment, legal title must have passed to the customer, the customer must have the significant risks and rewards of ownership and where acceptance is not a formality, the customer must have accepted the product or service. Heska’s principal terms of sale are FOB Shipping Point, or equivalent, and, as such, we primarily transfer control and record revenue for product sales upon shipment. If a performance obligation to the customer with respect to a sales transaction remains unfulfilled following shipment (typically owed installation), revenue recognition for that performance obligation is deferred until such commitments have been fulfilled. For extended warranty and service plans, control transfers to the customer over the term of the arrangement and as such the revenue is recognized ratably based upon the period of time elapsed under the arrangement.

Our revenue under subscription agreements relates to operating-type lease ("OTL") arrangements or sales-type lease ("STL") arrangements. Determination of an OTL or STL is primarily determined as a result of the length of the contract as compared to the estimated useful life of the instrument, among other factors. Leases are outside of the scope of ASC 606 and are therefore accounted for in accordance with ASC 842, Leases. A STL would result in earlier recognition of instrument revenue as compared to an OTL, which is generally upon installation of the instruments. Instrument lease revenue for our OTL subscription agreements is recognized on a straight-line basis over the life of the lease and is included with the predominant non-lease components in consumables revenue. For instrument only OTL agreements, operating lease income is

recognized on a straight-line basis over the term of the lease. The cash collected under both arrangements is over the term of the contract. The OTLs and STLs are not cancellable until after an initial term. See below for additional information on our lease accounting policies.

For contracts with both lease and non-lease components, the Company allocates the contracts' transaction price for each component on a relative standalone selling price basis using our best estimate of the standalone selling price of each distinct product or service in the contract. When available, the method used to estimate the standalone selling price is the price observed in standalone sales to customers. When prices in standalone sales are not available, we use a cost-plus margin approach. Changes in these values can impact the amount of consideration allocated to each component of the contract. Allocation of the transaction price is determined at the contracts' inception. The Company does not adjust the transaction price for the effects of a significant financing component when the period between the transfer of the promised good or service to the customer and payment for that good or service by the customer is expected to be one year or less.

To the extent the transaction price includes variable consideration, such as future payments based on consumable usage over time, we apply judgment to determine if the variable consideration should be constrained. As the variable consideration is highly susceptible to factors outside of the Company’s influence, and the potential values contain a broad range of possible outcomes given all potential amounts of consumption that could occur, it is likely that a significant revenue reversal would occur should the variable consideration be estimated at an amount greater than the minimum stated amount until such a time as the uncertainty is resolved. For our subscription agreements with variable consideration based on consumable usage over time, the variable consideration is allocated to the non-lease components upon resolution of the uncertainty and is included in consumables revenue.

We generate OVP revenue through contract manufacturing agreements with customers. Revenue from these customer contracts is generally recognized upon shipment or acceptance by our customer, under the same guidelines noted above for other outright product sales. Heska assessed the over-time criteria within ASC 606 and concluded that while 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. Therefore, point in time revenue recognition has been determined to be appropriate.

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 and intent to make payments in accordance with arrangements. For contracts with multiple performance obligations, we exercise judgment in allocating the transaction price for each performance obligation based on an estimated standalone selling price for each distinct product or service. We do not generally allow return of products or instruments. Distributor rebates are recorded as a reduction to revenue.

Refer to Note 2 for additional disclosures required by ASC 606.

Leases

The Company acts as a lessee and a lessor. As a lessee, the Company leases buildings, office equipment, and vehicles. As a lessor, the Company enters into sales-type and operating leases as part of its subscription agreements.

The Company determines if an arrangement is a lease at inception based on whether control of an identified asset is transferred. For leases where the Company is the lessee, ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based

on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit interest rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as amortization expense and interest expense. The Company has lease agreements which require payments for lease and non-lease components and has elected to account for these as a single lease component for our building and office equipment leases, but as separate components for our vehicle leases.

As a lessor, our subscription agreements relate to both OTL arrangements and STL arrangements. For a STL, instrument revenue is generally recorded upon installation of the instruments and the cost of the customer-leased instruments is removed from inventory and recognized in the Consolidated Statements of (Loss) Income. There is no residual value taken into consideration as it does not meet our capitalization requirements. For our OTL agreements that include both lease and non-lease components, revenue is recognized on a straight-line basis over the term of the lease and is included with the predominant non-lease components in consumables revenue. For instrument only OTL agreements, operating lease income is recognized on a straight-line basis over the term of the lease. For an OTL, the costs of customer-leased instruments are recorded within property and equipment in the accompanying Consolidated Balance Sheets and depreciated over the instrument’s estimated useful life. The depreciation expense is reflected in cost of revenue in the accompanying Consolidated Statements of (Loss) Income.

For leases that commenced before the January 1, 2019 effective date of ASC 842, the Company elected the permitted practical expedients to not reassess the following: (i) whether any expired or existing contracts contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases. The Company also elected to exclude leases with a term of 12 months or less from the recognized ROU assets and lease liabilities.

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 requisite service period of the award generally using the straight-line method.

Advertising Costs

Advertising costs are expensed as incurred and are included in sales and marketing expenses. Advertising expenses were $0.4 million for the year ended December 31, 2020, $0.3 million for the year ended December 31, 2019, and $0.2 million for the year ended December 31, 2018.

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 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 certain foreign subsidiaries is the local currency. Accordingly, assets and liabilities of these subsidiaries 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. Gains and losses arising from intercompany foreign currency transactions that are of a long-term investment nature are reported as a component of Accumulated other comprehensive income in the Consolidated Balance Sheets.

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. Extended warranties are sold to our customers and revenue is recognized over the term of the warranty agreement, as expected costs are incurred.

Correction of an Immaterial Error

During the fourth fiscal quarter of 2020, the Company recorded an out-of-period adjustment that impacted the Consolidated Balance Sheets, Consolidated Statements of (Loss) Income and Consolidated Statements of Comprehensive (Loss) Income. The adjustment related to an error in the calculation of non-cash interest expense relating to the Company's Notes. This error resulted in an overstatement of non-cash interest expense of $0.7 million in 2019, $0.6 million in each of the first and second fiscal quarters of 2020 and $0.5 million in the third fiscal quarter of 2020. The error also resulted in an overstatement of Convertible Notes, net, and Deferred Tax Liability of $0.7 million and $0.2 million, respectively as of December 31, 2019; $1.4 million and $0.3 million, respectively, as of March 31, 2020; $2.0 million and $0.4 million, respectively, as of June 30, 2020; and $2.5 million and $0.6 million, respectively, as of September 30, 2020. The Company assessed the materiality of these errors on the previously issued interim and annual financial statements in accordance with SEC Staff Accounting Bulletin No. 99 and No. 108. The Company concluded that the errors were not material to any of the previously issued consolidated financial statements and the impact of correcting these errors in the year ended December 31, 2020 is not material to the consolidated financial statements.

The impact of this adjustment resulted in a fourth quarter period decrease in interest expense of $2.5 million and a decrease in income tax benefit of $0.6 million. The Company also recorded a decrease in Convertible Notes, net, of $2.5 million, and a reduction in Deferred Tax Liability of $0.6 million as of December 31, 2020.

Adoption of New Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326), which requires 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. Subsequent to the issuance of ASU 2016-13, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, in November 2018. This ASU clarifies that receivables from operating leases are accounted for using the lease guidance and not as financial instruments. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, which further clarifies and improves guidance related to accounting for credit losses. In May 2019, the FASB issued ASU 2019-05, Financial Instruments - Credit Losses (Topic 326). This ASU provides relief to certain entities adopting ASU 2016-13. The amendment provides entities with an option to irrevocably elect the fair value option for certain financial assets. The Company adopted ASU 2016-13 with a cumulative-effect adjustment in retained earnings as of January 1, 2020. The impact of the adoption was not material to the Company's consolidated financial statements.

Accounting Pronouncements Not Yet Adopted    

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to the accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740, and also clarifies and amends existing guidance to improve consistent application. This guidance will be effective for interim and annual periods beginning after December 15, 2020, and early adoption is permitted. We evaluated the impact of the standard on our consolidated financial statements and do not expect the standard to have a material impact on our consolidated financial statements and disclosures.

In January 2020, the FASB issued ASU 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815). The amendments in this ASU clarify the interaction between the accounting for investments in equity securities, investment in equity method and certain derivatives instruments. The ASU is expected to reduce diversity in practice and increase comparability of the accounting for these interactions. This guidance will be effective for fiscal years beginning after December 15, 2020. We evaluated the impact of the standard on our consolidated financial statements and do not expect the standard to have a material impact on our consolidated financial statements and disclosures.

In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40), which simplifies the accounting for certain convertible instruments. The update reduces the number of accounting models for convertible debt instruments and convertible preferred stock. Convertible debt will be accounted for as a single liability measured at its amortized cost and convertible preferred stock will be accounted for as a single equity instrument measured at its historical cost, as long as no other features require bifurcation and recognition as derivatives. The update also requires the if-converted method to be used for convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. The guidance may be early adopted for fiscal years beginning after December 15, 2020,

and interim periods within those fiscal years.

The Company has elected to early adopt ASU 2020-06 as of January 1, 2021. The Notes are a convertible instrument with a cash-conversion feature that is accounted for within the scope of ASC 470-20 and will be impacted by adopting ASU 2020-06. The Company has elected to apply the modified retrospective method wherein the Company will recognize a cumulative-effect adjustment to the opening balance of retained earnings (January 1, 2021). Further, the Company will not restate EPS in the prior periods. The Company calculated the cumulative-effect adjustment as of January 1, 2021 by comparing (i) the historical amortization schedule for the Notes through December 31, 2020 and (ii) an updated amortization schedule wherein the conversion feature within the Notes would not be separated as an equity component and subsequently recognized as non-cash interest expense under ASC 835-30. As a result of ASU 2020-06, while cash interest expense is not impacted, non-cash interest accretion is limited to the amortization of debt issuance costs under ASC 835-30. Therefore, the Company prepared its transition journal entries by (i) reversing the conversion feature amount recorded in APIC and (ii) reversing the difference in non-cash interest expense via retained earnings. The expected impact on retained earnings is $4.3 million.

In October 2020, the FASB issued ASU 2020-10, Codification Improvements, which updates various codification topics by clarifying or improving disclosure requirements to align with the SEC's regulations. This guidance will be effective for annual periods beginning after December 15, 2020, for public entities. The Company will adopt as of the reporting period beginning January 1, 2021. We evaluated the impact of the

standard on our consolidated financial statements and do not expect the standard to have a material impact on our consolidated financial statements and disclosures.

Revenue from Contract with Customer [Abstract]

REVENUE

REVENUE

We separate our goods and services among two reportable segments, North America and International. The two segments consist of revenue originating from:

•North America: including the United States, Canada and Mexico

•International: all geographies outside North America, currently consisting primarily of Australia, France, Germany, Italy, Malaysia, Spain and Switzerland

Refer to Note 18 for further detail regarding the change in reportable segments which required recast of prior period presentation.

The following table summarizes our segment revenue (in thousands):

Remaining Performance Obligations

Remaining performance obligations represent the aggregate transaction price allocated to performance obligations with an original contract term greater than one year which are fully or partially unsatisfied at the end of the period. Remaining performance obligations include noncancelable purchase orders, the non-lease portion of minimum purchase commitments under long-term supply arrangements, extended warranty, service and other long-term contracts. Remaining performance obligations do not include revenue from contracts with customers with an original term of one year or less, revenue from long-term supply arrangements with no minimum purchase requirements, revenue expected from purchases made in excess of the minimum purchase

requirements, or revenue from instruments leased to customers. While the remaining performance obligation disclosure is similar in concept to backlog, the definition of remaining performance obligations excludes leases and contracts that provide the customer with the right to cancel or terminate for convenience with no substantial penalty, even if historical experience indicates the likelihood of cancellation or termination is remote. Additionally, the Company has elected to exclude contracts with customers with an original term of one year or less from remaining performance obligations.

As of December 31, 2020, the aggregate amount of the transaction price allocated to remaining minimum performance obligations was approximately $144.6 million. As of December 31, 2020, the Company expects to recognize revenue as follows (in thousands):

Year Ending December 31,	Revenue
2021	$	32,976
2022	30,089
2023	26,992
2024	22,668
2025	16,713
Thereafter	15,129
	$	144,567

Contract Balances

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled contract assets, deferred revenue, and customer deposits and billings in excess of revenue recognized. In addition, the Company defers certain costs incurred to obtain contracts.

Contract Assets

Certain unbilled amounts related to long-term contracts for which we provide a free term to the customer are recorded in "Other current assets" and "Other non-current assets" on the accompanying Consolidated Balance Sheets. The collection of these balances occurs over the term of the underlying contract. The balances as of December 31, 2020 were $1.2 million and $4.1 million for current and non-current assets, respectively, shown net of related unearned interest. The balances as of December 31, 2019 were $1.1 million and $3.7 million for current and non-current assets, respectively, shown net of related unearned interest.

Contract Liabilities

The Company receives cash payments from customers for licensing fees or other arrangements that extend for a specified term. These contract liabilities are classified as either current or long-term in the Consolidated Balance Sheets based on the timing of when the Company expects to recognize revenue. As of December 31, 2020 and 2019, contract liabilities were $8.9 million and $8.7 million, respectively, and are included within "Deferred revenue, current, and other" and "Deferred revenue, non-current" in the accompanying Consolidated Balance Sheets. The decrease in the contract liability balance during the year ended December 31, 2020 is approximately $4.2 million of revenue recognized during the period, offset by approximately $3.8 million of additional deferred sales in 2020 and the acquisition of scil contract liabilities of $0.6 million. The decrease in the contract liability balance during the year ended December 31, 2019 is $3.1 million of revenue recognized during the period, offset by $2.2 million of additional deferred sales. Contract liabilities are reported on the accompanying Consolidated Balance Sheets on a contract-by-contract basis.

Contract Costs

The Company capitalizes certain direct incremental costs incurred to obtain customer contracts, typically sales-related commissions, where the recognition period for the related revenue is greater than one year. Contract costs are classified as current or non-current, and are included in "Other current assets" and "Other non-current assets" in the Consolidated Balance Sheets based on the timing of when the Company expects to recognize the expense. Contract costs are generally amortized into selling and marketing expense with a certain percentage recognized immediately based upon placement of the instrument with the remainder recognized on a straight-line basis (which is consistent with the transfer of control for the related goods or services) over the average term of the underlying contracts, approximately 6 years. Management assesses these costs for impairment at least quarterly on a portfolio basis and as “triggering” events occur that indicate it is more-likely-than-not that an impairment exists. The balance of contract costs as of December 31, 2020 and December 31, 2019 was $3.0 million and $2.7 million, respectively. Amortization expense for the year ended December 31, 2020 was approximately $1.0 million, offset by approximately $1.2 million of additional contract cost capitalization and $0.1 million of the acquisition of scil contract costs. Amortization expense for the year ended December 31, 2019 was approximately $0.9 million, offset by approximately $1.1 million of additional contract costs capitalized. Contract costs are calculated and reported on a portfolio basis.

ACQUISITION AND RELATED PARTY ITEMS

scil Acquisition

On April 1, 2020, the Company completed the acquisition of scil animal care company GmbH (“scil”) from Covetrus, Inc. The Company purchased 100% of the capital stock of scil for an aggregate purchase price of $110.3 million in cash. The acquisition represents a key milestone in the Company's long-term strategic plan, creating a global veterinary diagnostics company with leadership positions in key geographic markets. The purchase price exceeded the identifiable net assets, resulting in goodwill of $46.0 million, primarily attributable to the synergies expected from the expanded market opportunities with our offerings and the experienced workforce acquired. Of the goodwill acquired, $37.3 million is allocated to our International segment and $8.7 million is allocated to our North America segment. All of the goodwill is tax deductible for purposes of calculating Controlled Foreign Corporation ("CFC") tested income, which may result in a decrease to the Company's future U.S. federal tax liability.

The acquisition was accounted for using the acquisition method of accounting in accordance with ASC 805, Business Combinations, which requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. As such, the total purchase consideration was allocated to the assets acquired and liabilities assumed based on a preliminary estimate of their fair values as of April 1, 2020.

The information below represents the preliminary purchase price allocation of scil (in thousands):

	April 1, 2020
Total purchase consideration	$	110,290
Cash and cash equivalents	5,889
Accounts receivable	10,707
Inventories	11,278
Net investment in leases, current	311
Prepaid expenses	1,692
Other current assets	1,338
Property and equipment, net	19,320
Operating lease right-of-use assets	877
Other intangible assets, net	44,517
Net investment in leases, non-current	1,027
Investments in unconsolidated affiliates	55
Other non-current assets	291
Total assets acquired	97,302
Accounts payable	8,221
Accrued liabilities	7,067
Operating lease liabilities, current	356
Deferred revenue, current, and other	3,220
Deferred revenue, non-current	94
Operating lease liabilities, non-current	529
Deferred tax liability	13,249
Other liabilities	276
Net assets acquired	64,290
Goodwill	46,000
Total fair value of consideration transferred	$	110,290

The Company's preliminary estimates of fair values of the assets acquired and the liabilities assumed are based on the information currently available, and the Company is continuing to evaluate the underlying inputs and assumptions used in its valuations. Accordingly, these preliminary estimates are subject to change during the measurement period, which is up to one year from the date of the acquisition. A decrease in the fair value of assets acquired or an increase in the fair value of liabilities assumed in the acquisition from those valuations would result in a corresponding change in the amount of goodwill from the acquisition. During the fourth quarter, the Company made certain valuation adjustments to provisional amounts previously recognized. These adjustments resulted in a net increase of $0.2 million in goodwill, primarily due to changes in estimated taxes and an increase in accrued liabilities assumed.

Per the tax indemnification included in the purchase agreement of scil animal care company GmbH, the seller has indemnified the Company for $1.1 million related to uncertain tax positions taken in prior years. The outcome of this arrangement will either be settled or expire due to lapse of statute of limitations by 2027. As of December 31, 2020, approximately $0.8 million of the indemnification agreement remains outstanding.

Intangible assets acquired, amortization method and estimated useful life as of April 1, 2020, was as follows (dollars in thousands):

	Useful Life	Amortization Method	Fair Value
Customer relationships	10 years	Straight-line	$	36,272
Internally developed software	7 years	Straight-line	353
Backlog	0.2 years	Straight-line	210
Non-compete agreements	2 years	Straight-line	60
Trade name subject to amortization	0.8 years	Straight-line	66
Trademarks and trade names not subject to amortization	n/a	Indefinite	7,556
Total intangible assets acquired			$	44,517

scil generated net revenue of $61.3 million and a net loss of $1.1 million for the period from April 1, 2020 to December 31, 2020.

The Company incurred acquisition related costs of approximately $6.3 million and $0.7 million for the years ended December 31, 2020 and 2019, respectively, which are included within general and administrative expenses on our Consolidated Statements of (Loss) Income.

Net (loss) income attributable to Heska Corporation	$	(15,215)	$	(2,487)

The pro forma financial information presented above has been prepared by combining our historical results and the historical results of scil and further reflects the effect of purchase accounting adjustments, including: (i) amortization of acquired intangible assets, (ii) the impact of certain fair value adjustments such as depreciation on the acquired property, plant and equipment, and (iii) historical intercompany sales between the Company and scil. The unaudited pro forma results are presented for informational purposes only and are not necessarily indicative of what actual results of operations would have been if the acquisition had occurred as the beginning of the period presented, nor are they indicative of future results of operations.

CVM

On December 5, 2019, Heska entered into a definitive agreement to purchase 100% of the outstanding shares of CVM Diagnostico Veternario S.L. and CVM Ecografia S.L. (“CVM”, collectively), primarily to expand international operations in Europe. CVM is headquartered in Tudela, outside of Madrid, Spain. CVM mainly

operates in Spain. The terms of the agreement transferred control of CVM upon signing, and the transfer of the purchase price of approximately $14.4 million and shares occurred in January 2020. The purchase price exceeded the fair value of the identifiable net assets and, accordingly, $9.0 million was allocated to goodwill within the International segment based on the purchase price allocation, all of which is tax deductible for purposes of calculating CFC tested income.

The fair values allocated to CVM's assets and liabilities as of the acquisition date, as well as the purchase price, are reflected in the table below (in thousands):

Purchase Price	December 5, 2019
Consideration paid to former owners	$	14,420
Cash and cash equivalents	1,226
Accounts receivable	583
Inventories	1,621
Other current assets	1,186

Other long-term borrowings	(1,109)
Other liabilities	(157)
Net assets acqiured	5,461
Goodwill	8,959
Total fair value of consideration transferred	$	14,420

During the year ended December 31, 2020, the Company made certain valuation adjustments to provisional amounts previously recognized. These measurement period adjustments resulted in a net $110 thousand increase of goodwill, primarily due to fair value adjustments resulting in a decrease in net identifiable assets acquired. The Company finalized the accounting for the CVM acquisition in the fourth quarter of 2020.

Intangible assets acquired, amortization method and estimated useful life as of December 5, 2019, were as follows (dollars in thousands):

	Useful Life	Amortization Method	Fair Value
Customer relationships	6 years	Straight-line	$	2,440
Trade name	4 years	Straight-line	111
Developed technology	n/a	Indefinite	57
			$	2,608

CVM generated net revenue of $0.8 million and net income of $0.1 million, for the period from December 6, 2019 to December 31, 2019.

The Company incurred acquisition related costs of approximately $0.6 million and $0.1 million for the years ended December 31, 2020 and 2019, respectively, which are included within general and administrative expenses on our Consolidated Statements of (Loss) Income.

Optomed

On February 22, 2019, Heska acquired 70% of the equity of Optomed, a French-based endoscopy company, in exchange for approximately $0.2 million in cash and the assumption of approximately $0.4 million in debt. On October 5, 2020, the Company acquired the remaining 30% minority interest in Optomed for a purchase price of $0.5 million, allowing the Company to assume full control of the business operations.

Purchase Agreement for Certain Assets

Cuattro, LLC ("Cuattro") is owned by Kevin S. Wilson, the CEO and President of the Company. On December 21, 2018, the Company closed a transaction (the "Asset Acquisition") to acquire certain assets from Cuattro, all related to the North America segment. Pursuant to the Asset Acquisition, dated November 26, 2018, the Company issued 54,763 shares of the Company's common stock, $0.01 par value per share (the "Common Stock"), to Cuattro on the Closing Date, at an aggregate value equal to approximately $5.4 million based on the adjusted closing price per share of the Common Stock as reported on the Nasdaq Stock Market on the Asset Acquisition agreement date. These shares were issued to Cuattro in a private placement in reliance upon an exemption from the registration requirements of the Securities Act pursuant to Section 4(a)(2) thereof and the safe harbor provided by Rule 506 of Regulation D promulgated thereunder. In addition to the Common Stock, the Company paid cash in the amount of $2.8 million to Cuattro as part of the transaction. The total purchase price was determined based on a valuation report from an independent third party. Part of the Asset Acquisition was an agreement to terminate the supply and license agreement that Heska had been operating under since the acquisition of Cuattro Veterinary USA, LLC.

The Company evaluated the acquisition of the purchased assets under ASC 805, Business Combinations and ASU 2017-01, Business Combinations (Topic 805) and concluded that as substantially all of the fair value of the gross assets acquired is concentrated in an identifiable group of similar assets, the transaction did not meet the requirements to be accounted for as a business combination and therefore was accounted for as an asset

acquisition. Accordingly, the $8.2 million purchase price of the purchased assets was allocated entirely to an identifiable intangible asset amortizing on a straight-line basis over a 10-year useful life.

Related Party Activities

Cuattro charged the Company $0, $6 thousand and $4.6 million during 2020, 2019 and 2018, respectively, primarily related to digital imaging products, pursuant to an underlying supply contract that contained minimum purchase obligations, software and services as well as other operating expenses. Pursuant to the Asset Acquisition, Cuattro was obligated, without further compensation, to assist the Company with the implementation of a third-party image hosting platform and necessary data migration. The implementation and migration were completed, and as of December 31, 2020 there will be no further related party activities with Cuattro.

CVM management conducts related party activities with Practice Clinicas Veterinarias Moviles, S.L. ("CVM Practice"), which is owned by CVM's management. During the year ended December 31, 2020, the Company fully paid the balance of a loan due to CVM Practice of approximately $1.1 million, which is included in "Payments of related party debt" on the Consolidated Statements of Cash Flows. CVM also leases two warehouses from CVM Practice. CVM Practice charged CVM $31 thousand and $0 during the year ended December 31, 2020 and 2019, respectively, all of which is related to lease payments. The right-of-use asset and lease liability amounts related to the warehouse leases were approximately $0.2 million and $0 as of December 31, 2020 and 2019, respectively. The change from December 31, 2019 to December 31, 2020 is due to a reorganization regarding CVM management and the control that they exercise subsequent to the scil acquisition.

Investment in Unconsolidated Affiliates	$	6,704	$	7,424

Equity Method Investment

On September 24, 2018, we invested approximately $5.1 million, including costs, to acquire an equity interest in a business as part of our product development strategy. As of December 31, 2020, our ownership interest in the business was 29.1%. In connection with the investment, the Company entered into a Manufacturing Supply Agreement that grants the Company global exclusivity to specified products to be delivered under the agreement for a 15-year period that begins upon the Company's receipt and acceptance of an initial order under the agreement. The Company accounts for this investment using the equity method of accounting. Under the equity method, the carrying value of the investment is adjusted for the Company's proportionate share of the investee's reported earnings or losses with the corresponding share of earnings or losses reported as Equity in losses of unconsolidated affiliates, listed below Net income before equity in losses of unconsolidated affiliates within the Consolidated Statements of (Loss) Income.

Non-Marketable Equity Security Investment

On August 8, 2018, the Company invested approximately $3.0 million, including costs, in exchange for preferred stock. The Company's investment is a non-marketable equity security, recorded using the measurement alternative of cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes.

As part of the agreement, the Company entered into a Supply and License Agreement, which provides that the investee produce and commercialize products that will enhance the Company's diagnostic portfolio. As part of this agreement, the Company made upfront payment of $1.0 million related to a worldwide exclusive license agreement over a 20-year period, recorded in both short and long-term other assets. In addition, the agreement provides for an additional contingent payment of $10.0 million, relating to the successful achievement of sales milestones. This potential future milestone payment has not yet been accrued as it is not deemed by the Company to be probable at this time.

Both parties in this arrangement are active participants and are exposed to significant risks and rewards dependent on the commercial success of the activities of the collaboration. The parties are actively working on developing and testing the product as well as funding the research and development. Heska classifies the amounts paid for research and development work within the North America segment research and development operating expenses. Expense is recognized ratably when incurred and in accordance with the development plan.

Our investments are evaluated for impairment if a triggering event occurs. The Company evaluated both its equity method investment and non-marketable equity security investment for losses other than temporary as of December 31, 2020, and determined that no indications of an impairment existed.

In 2020, we had total income tax expense of $0.2 million, including $0.6 million in domestic deferred income tax expense and $2.2 million in foreign deferred income tax benefit, and $1.8 million in current income tax expense. In 2019, we had total income tax benefit of $1.4 million, including approximately $1.9 million in domestic deferred income tax benefit and $0.1 million of foreign deferred income tax expense, a non-cash benefit, and approximately $0.4 million in current income tax expense. In 2018, we had total income tax benefit of $2.1 million, including $2.3 million in domestic deferred income tax benefit, a non-cash benefit, and $0.1 million in current income tax expense. Income tax expense increased in 2020 from 2019 due to foreign income inclusion, executive compensation limitations and acquisition related costs. Income tax benefit decreased in 2019 from 2018 due to executive compensation limitations and lower excess tax benefits related to stock-based compensation deductions.

Cash paid for income taxes for the years ended December 31, 2020, 2019 and 2018 was $993 thousand, $128 thousand and $36 thousand, respectively.

The Company is subject to income taxes in the U.S. 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. Although the U.S. and many states generally have statutes of limitations ranging from 3 to 5 years, those statutes could be extended due to the Company’s net operating loss and tax credit carryforward positions in several of the Company's tax jurisdictions. In the U.S., the tax years 2017 - 2019 remain open to examination by the Internal Revenue Service.

As of December 31, 2020, the Company had net operating loss carryforwards ("NOL") of approximately $35.0 million, a foreign tax credit of $64 thousand and a domestic research and development tax credit carryforward of approximately $1.3 million. Our federal NOL is expected to expire as follows if unused: $22 million in 2021 through 2022, $5.4 million in 2024 through 2025 and $0.5 million in 2027 and later. Our foreign NOL of $7.1 million does not have an expiration date.

The Company considered multiple factors in assessing the need for an increase in the partial valuation allowance against the Company’s deferred tax assets as of December 31, 2020. Significant factors such as employee stock compensation expenses from achievement of Company performance metrics, executive compensation limitations and required capitalization of research and development expenses beginning in 2022 have negatively impacted our future taxable income projections. These future projections indicate a larger portion of the Company’s deferred tax assets will likely expire unrealized. As a result, the Company recorded an additional $0.8 million tax effected increase to the current partial valuation allowance against the Company's worldwide net operating losses and tax credits for the year ended December 31, 2020. As of December 31, 2020, the Company had a deferred tax asset of approximately $10.1 million from net operating losses and tax credits and a net partial valuation allowance of approximately $6.4 million recorded against these deferred tax assets. The Company will continue to closely monitor the need for an additional valuation allowance against its deferred tax assets in each subsequent reporting period which can be impacted by actual operating results compared to the Company's forecast.

ASC Topic 740 prescribes the accounting for uncertainty in income taxes recognized in the financial statements in accordance with the other provisions contained within this guidance. This topic prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by the taxing authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50% likely or being realized upon ultimate audit settlement. In the normal course of business, the Company's tax returns are subject to examination by various taxing authorities. Such examination may result in future tax and interest assessments by these taxing authorities for uncertain tax positions taken in respect to certain matters.

The following provides a reconciliation of unrecognized tax benefits which are included in Other liabilities within the Consolidated Balance Sheets (in thousands):

	Year Ended December 31,
	2020		2019
Balance at beginning of period	$	—	$	—
Acquired additions based on prior year tax positions	(1,072)		—
Reductions from lapse in statutes of limitations	358		—
Currency Translation Adjustment	$	(94)	—
Balance at the end of period	$	(808)	$	—

The total amount of unrecognized tax benefits, which are included in other liabilities within the combined balance sheets as of December 31, 2020 was approximately $0.8 million, which may impact the effective tax rate if recognized. These unrecognized tax benefits were recognized as part of the acquisition of scil animal care company GmbH. Per the tax indemnification included in the purchase agreement, the seller has indemnified the Company for these other liabilities, which would reduce the economic impact to the Company if these positions were settled with tax authorities. It is expected that the amount of unrecognized tax benefits will change in the next 12 months; however, the Company does not expect the change to have a material impact on the combined financial statements. The Company recognizes interest and penalties related to uncertain tax positions in income tax (benefit)/expense. Interest and penalties accrued as of December 31, 2020 are $19.0 thousand.

As of December 31, 2020, the Company had accumulated undistributed earnings generated by foreign subsidiaries of approximately $2.9 million, which would be subject to U.S. taxes and foreign withholding taxes of approximately $145 thousand if repatriated. The Company had previously considered these earnings as a possible cash source through repatriation to the U.S. As of December 31, 2020, the Company has changed its assertion on these earnings and now considers them to be indefinitely reinvested and expects the future U.S. cash generation to be sufficient to meet future U.S. cash needs. If the Company decides to repatriate these foreign earnings, it would need to adjust its income tax provision in the period it determined that the earnings would no longer be indefinitely invested outside the United States.

EARNINGS PER SHARE

Earnings Per Share [Abstract]

EARNINGS PER SHARE

EARNINGS PER SHARE

Basic earnings per share ("EPS") is computed by dividing net income attributable to the Company 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 awards 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 following is a reconciliation of the weighted-average shares outstanding used in the calculation of basic and diluted earnings per share ("EPS") for the years ended December 31, 2020, 2019 and 2018 (in thousands, except per share data):

	Years ended December 31,
	2020		2019		2018
Net (loss) income attributable to Heska Corporation	$	(14,399)	$	(1,465)	$	5,850
Basic weighted-average common shares outstanding	8,653		7,446		7,220
Assumed exercise of dilutive stock options and restricted shares	—		—		636
Diluted weighted-average common shares outstanding	8,653		7,446		7,856
Basic (loss) earnings per share attributable to Heska Corporation	$	(1.66)	$	(0.20)	$	0.81
Diluted (loss) earnings per share attributable to Heska Corporation	$	(1.66)	$	(0.20)	$	0.74

The following potentially outstanding common shares from convertible preferred stock, convertible senior notes, stock options and restricted stock awards were excluded from the computation of diluted EPS because the effect would have been antidilutive (in thousands):

	Years ended December 31,
	2020	2019	2018
Convertible preferred stock	458	—	—
Convertible senior notes	118	—	—
Stock options and restricted shares	328	300	111
	904	300	111

As more fully described in Note 16, our Notes are convertible under certain circumstances, as defined in the indenture, into a combination of cash and shares of our common stock. The Company intends to settle the principal value of the Notes in cash and issue shares of our common stock to settle the intrinsic value of the conversion feature. The Company will use the treasury stock method when calculating the potential dilutive effect of the conversion feature on earnings per share, if any. Potential dilution upon conversion of the Notes occurs when the average market price per share of our common stock is greater than the conversion price of the Notes of $86.63. For the periods presented, all potentially dilutive shares relating to the Notes were not included in the computation of diluted EPS as the effect would have been antidilutive.

As discussed in Note 12, the Company issued and sold an aggregate of 122,000 shares of its Preferred Stock to certain investors in a private placement offering. The shares were converted into 1,508,964 shares of Public Common Stock, effective on April 21, 2020. The potential dilutive effect of the convertible preferred stock was calculated using the if-converted method for the period the preferred shares were outstanding. For the twelve months ended December 31, 2020, these shares were excluded from the computation of diluted EPS because the effect would have been antidilutive.

CAPITAL STOCK

Stock Plans

We have two stock option plans which authorize granting of stock options, restricted stock awards 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"), which was later amended in December 2018 to be renamed the "Stock Incentive Plan." In May 2012, stockholders approved an amendment 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. The plan was further amended in May 2016, May 2018, and April 2020 to increase the number of shares authorized for issuance by 500,000, 250,000, and 300,000 shares, respectively. 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, 2020 was 151,605.

Stock Options

The stock options granted by the Board of Directors may be either incentive stock options ("ISOs") or non-qualified stock options ("NQs") and may include time-based vesting terms and/or be tied to Company and market-related performance metrics. 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. 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 Stock Incentive Plan, in the event we are sold or merged, outstanding options will either be assumed by the surviving corporation or vest immediately.

We use the Black-Scholes option-pricing model to estimate the fair value of time-vested and performance stock options granted, which includes four key inputs: expected term, expected volatility, risk-free interest rate and expected dividends. Our expected term is estimated based on historical exercise patterns. Our expected volatility input was estimated based on our historical stock price volatility. Our risk-free interest rate input was determined based on the U.S. Treasury yield curve at the time of option issuance. Our expected dividends inputs were zero in all periods as we did not anticipate paying dividends in the foreseeable future. For options tied to market performance, the fair value used in our expense recognition method is measured based on the number of shares granted, and a Monte Carlo simulation model, which incorporates the probability of the achievement of the market-related performance goals as part of the grant date fair value. We recognize forfeitures as they occur.

Time Vesting Stock Options

The fair value of each time vesting option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:

	2020	2019	2018
Risk-free interest rate	3.64%	1.62%	2.66%
Expected lives	5.3 years	4.7 years	4.9 years
Expected volatility	46%	40%	40%
Expected dividend yield	0%	0%	0%

A summary of our time vesting stock option activity is as follows:

	Year Ended December 31,
	2020
	Options	Weighted Average Exercise Price
Outstanding at beginning of period	536,315	$	54.86
Granted at market	83,250	$	69.27
Forfeited	(42,307)	$	76.24
Expired	(28,691)	$	69.25
Exercised	(84,335)	$	40.64
Outstanding at end of period	464,232	$	57.18
Exercisable at end of period	291,334	$	46.53

The total estimated fair value of time vesting stock options granted was computed to be approximately $2.4 million, $2.6 million and $4.4 million during the years ended December 31, 2020, 2019 and 2018, 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 $28.66, $29.89 and $28.81 during the years ended December 31, 2020, 2019 and 2018, respectively. The total intrinsic value of options

exercised was $5.0 million, $12.8 million and $10.5 million during the years ended December 31, 2020, 2019 and 2018, respectively. The cash proceeds from options exercised were $3.4 million, $1.0 million and $3.2 million during the years ended December 31, 2020, 2019 and 2018, respectively.

The following table summarizes information about time vesting stock options outstanding and exercisable at December 31, 2020.

As of December 31, 2020, there was approximately $3.6 million of total unrecognized compensation cost related to outstanding stock options. That cost is expected to be recognized over a weighted-average period of 1.63 years with all cost to be recognized by the end of August 2023, assuming all options vest according to the vesting schedules in place at December 31, 2020. As of December 31, 2020, the aggregate intrinsic value of outstanding options was approximately $41.1 million and the aggregate intrinsic value of exercisable options was approximately $28.9 million.

Performance Stock Options

On April 16, 2020, the Company granted a total of 240,000 performance-based stock options all with an exercise price of $60.94. Of the options granted,10,000 are tied to market-related vesting conditions and 230,000 are tied to Company performance metrics, including future product launches, future sales targets, operating performance, and EBITDA. Performance and market conditions must be achieved by December 31, 2023 otherwise the stock options are forfeited. All vested but unexercised options will expire April 15, 2030.

During the year ended December 31, 2020, 20,000 of the performance-based stock options were forfeited, leaving a total of 220,000 options outstanding as of December 31, 2020. The outstanding options had a weighted-average exercise price of $60.94, a weighted-average remaining contractual term of 9.29 years, and an aggregate intrinsic value of approximately $18.6 million. No options were exercisable as of December 31, 2020. For the year ended December 31, 2020, the weighted-average estimated fair value of the options granted was computed to be approximately $25.04 and the total estimated fair value was approximately $6.0 million. As of December 31, 2020, there was approximately $2.4 million of total unrecognized compensation cost that is expected to be recognized over a weighted average period of 1.80 years.

As of December 31, 2020, we reviewed each of the underlying corporate performance targets and determined that approximately 80,000 shares were related to corporate performance targets in which we did not deem achievement probable. No compensation expense had been recorded at any period prior to December 31, 2020. The unrecognized compensation cost associated with the performance options not deemed probable, based on grant date fair value, is approximately $2.0 million. Any change in the probability determination could accelerate the recognition of this expense.

Restricted Stock Awards

We have granted unvested restricted stock awards (“restricted stock”) to management and directors pursuant to the Stock Incentive Plan. The restricted stock awards have varying vesting periods, but generally become fully vested between one and four years after the grant date, depending on the specific award, performance targets met for performance based awards granted to management, and vesting period for time based awards. Management performance based awards are granted at the target amount of shares that may be earned and are tied to future sales targets, operating performance, and/or EBITDA. We valued the restricted stock awards related to service and/or company performance targets based on grant date fair value and expense over the period when achievement of those conditions is deemed probable. For restricted stock awards related to market conditions, we utilize a Monte Carlo simulation model to estimate grant date fair value and expense over the requisite period. We recognize forfeitures as they occur.

The following table summarizes restricted stock transactions for the year ended December 31, 2020:

	Restricted Stock	Weighted-Average Grant Date Fair Value Per Award
Non-vested as of December 31, 2019	335,667	$	74.29
Granted	69,823	$	87.29
Vested	(46,140)	$	68.80
Forfeited	(67,830)	$	73.27
Non-vested as of December 31, 2020	291,520	$	78.44

The weighted average grant date fair value of awards granted during the year was $87.29, $74.93, and $71.77 for the years ended December 31, 2020, 2019 and 2018, respectively. Fair value of restricted stock vested was $5.0 million, $0.3 million, and $4.4 million for the years ended December 31, 2020, 2019 and 2018, respectively.

As of December 31, 2020, there was approximately $5.5 million of total unrecognized compensation cost related to restricted stock awards with probable Company performance targets, as well as market and time vesting conditions. The Company expects to recognize this expense over a weighted average period of 1.4 years. As of December 31, 2020, we reviewed each of the underlying corporate performance targets and determined that approximately 129,000 shares of common stock were related to corporate performance targets in which we did not deem achievement probable. No compensation expense had been recorded at any period prior to December 31, 2020. The unrecognized compensation cost associated with the restricted stock awards not deemed probable, based on grant date fair value, is approximately $10.6 million. Any change in the probability determination could accelerate the recognition of this expense.

Employee Stock Purchase Plan

Under the 2020 Employee Stock Purchase Plan (the "ESPP"), we are authorized to issue up to 200,000 shares of common stock to our employees, of which 3,859 had been issued as of December 31, 2020. The ESPP provides for the issuance of shares of our common stock to participating employees. At the end of each designated offering period, which occurs every six months on June 30 and December 31, employees can elect to purchase shares of our common stock with contributions of up to 10% of their base pay, accumulated via payroll deductions, at an amount equal to 85% of the lower of our stock price on (i) the first trading day of the offering period, or (ii) the last trading day of the offering period.

We issued 10,069, 10,698 and 10,078 shares under the ESPP for the years ended December 31, 2020, 2019 and 2018, respectively. The weighted-average fair value of the purchase rights granted was $16.19, $18.10 and $18.14 per share for the years ended December 31, 2020, 2019 and 2018, respectively.

Series X Convertible Preferred Stock

On March 30, 2020, the Company completed a private placement offering in which the Company issued and sold an aggregate of 122,000 shares of its Series X Convertible Preferred Stock, par value $0.01 per share (the "Preferred Stock"). The shares of Preferred Stock issued and sold were priced at $1,000 per share (the “Stated Value”), resulting in gross proceeds of $122.0 million, less issuance costs of $0.2 million. The Company used approximately $111.0 million of the proceeds from the offering to fund the April 1, 2020 acquisition of scil and plans to use the remaining proceeds for working capital and general corporate purposes.

The offering was made pursuant to the Securities Purchase Agreement (the “Securities Purchase Agreement”), dated as of January 12, 2020, by and among the Company and certain investors, and subsequent amendment (the “Securities Purchase Agreement Amendment”) to the Securities Purchase Agreement, entered into by the Company and each investor on March 30, 2020 (the Securities Purchase Agreement as amended by the Securities Purchase Agreement Amendment, the “Amended Securities Purchase Agreement”).

The shares of Preferred Stock were convertible into shares of the Company’s Common Stock at an initial ratio of approximately 12.4 shares of Common Stock for each share of Preferred Stock (equivalent to a conversion price of approximately $80.85 per share of common stock), at the option of the holders of the Preferred Stock or the Company, subject to the Company possessing sufficient unissued and otherwise unreserved shares of Common Stock under the Company’s Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”). On April 14, 2020, the Company gave notice of its exercise of its right to convert the 122,000 shares of Preferred Stock into 1,508,964 shares of Public Common Stock (the "Conversion Shares") and the conversion was effective on April 21, 2020. The conversion resulted in dilution of less than 20% of total shares of the Company’s Public Common Stock currently issued and outstanding. A registration statement on Form S-3 (File No. 333-238005) registering the Conversion Shares for resale was filed by us with the SEC on May 5, 2020.

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES

Warranties

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 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 $0.5 million and $0.3 million as of December 31, 2020 and 2019.

Litigation

From time to time, the Company may be involved in litigation relating to claims arising out of its operations. The Company records accruals for outstanding legal matters when it believes it is probable that a loss will be incurred, and the amount can be reasonably estimated.

On February 18, 2020, a former managing director of scil filed a claim disputing the effective date of the termination of his management service agreement and the validity of the Company´s waiver of his two-year post-contractual non-compete obligation. The Company intends to defend itself against the claim. Whether or not this will be successful depends on complex facts and circumstances. The Company is, based on the advice of its legal counsel, confident that it will be successful in evidencing the effective date of the termination of the management service agreement and as such, no accrual has been recorded for this ongoing litigation. Additionally, we are indemnified by the scil acquisition agreement for this claim.

On October 10, 2018, we reached an agreement in principle to settle the complaint that was filed against the Company by Shaun Fauley on March 12, 2015 in the U.S. District Court Northern District of Illinois (the "Court") 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 (the "Fauley Complaint"). The settlement, which received the Court's approval on February 28, 2019 and was not

subsequently appealed by a class member, required us to make available a total of $6.8 million to pay class members, as well as to pay attorneys' fees and expenses to legal counsel to the class. The Company recorded the loss provision in the third quarter of 2018 in connection with the settlement agreement and does not have insurance coverage for the Fauley Complaint. The payment in respect of the settlement was made in full on April 3, 2019, and all activity related to the Fauley Complaint has ceased.

At December 31, 2020, 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.

Off-Balance Sheet Commitments

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

Purchase Obligations

The Company has contractual obligations with suppliers for unconditional annual minimum inventory purchases in the amounts of $25.0 million as of December 31, 2020.

CREDIT FACILITY AND LONG-TERM DEBT

CONVERTIBLE NOTES

Convertible Notes

On September 17, 2019, the Company issued $86.25 million aggregate principal amount of 3.750% Convertible Senior Notes due 2026, which included the exercise in full of an $11.25 million purchase option, to certain financial institutions as the initial purchasers of the Notes (the "Initial Purchasers"). The Notes are senior unsecured obligations of the Company. The Notes were issued pursuant to an Indenture, dated September 17, 2019 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee.

The net proceeds from the sale of the Notes were approximately $83.7 million after deducting the initial purchasers’ discounts and the offering expenses payable by the Company. The Company used approximately $12.8 million of the net proceeds from the Notes to repay all outstanding indebtedness on its

existing Credit Facility with JPMorgan Chase Bank, N.A., and an additional $2.0 million to fully fund a cash collateralized, letter of credit facility under a new Credit Facility. The Company subsequently terminated the Credit Facility with JPMorgan Chase Bank, N.A. on December 31, 2019. The Company expects to use the remainder of the net proceeds from the sale of the Notes to fund our intended expansion efforts, including through acquisitions of complementary businesses or technologies or other strategic transactions, and for working capital and other general corporate purposes.

The Notes are senior unsecured obligations of the Company and will rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of our unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries.

The Company pays interest on the Notes semiannually in arrears at a rate of 3.750% per annum on March 15 and September 15 of each year. The Notes are convertible based upon an initial conversion rate of 11.5434 shares of the Company’s common stock per $1,000 principal amount of Notes (equivalent to a conversion price of approximately $86.63 per share of common stock). The Notes would convert in full into 995,618 shares of common stock based on the initial conversion rate. The conversion rate will be subject to standard anti-dilution adjustments upon the occurrence of certain events but will not be adjusted for accrued and unpaid interest. The interest rate on the Notes may be increased by up to 0.50% upon the occurrence of certain events of default or non-timely filings until such matter has been cured.

The Indenture includes customary covenants, but no financial or operating covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities, and sets forth certain events of default and certain types of bankruptcy or insolvency events of default involving the Company after which the Notes become automatically due and payable. The Company can settle any conversions of the Notes in cash, shares of the Company’s common stock or a combination thereof, with the form of consideration determined at the Company’s election. The Company intends to settle the principal value of the Notes in cash and issue shares of the Company’s common stock to settle the intrinsic value of the conversion feature. There can be no guarantee, however, that any settlement will be affected by the Company as currently intended, and the timing and other factors of any settlement, many of which may be outside the Company's control, could impact the actual amounts to be settled in either cash or common stock.

The Notes will mature on September 15, 2026, unless earlier repurchased, redeemed or converted. Prior to March 15, 2026, holders may convert all or a portion of their Notes only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on December 31, 2019 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the 5 business day period after any 5 consecutive trading day period (the "Notes measurement period") in which the trading price per $1,000 principal amount of Notes for each trading day of the Notes measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; (3) with respect to any Notes called for redemption by the Company, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On and after March 15, 2026 until the close of business on the scheduled trading day immediately preceding the maturity date, holders may convert their Notes at any time, regardless of the foregoing circumstances. Holders of Notes who convert their Notes in connection with a notice of a redemption or a make-whole fundamental change (each as defined in the Indenture) may be entitled to a premium in the form of an increase in the conversion rate of the Notes.

The Company may not redeem the Notes prior to September 20, 2023. On or after September 20, 2023, the Company may redeem for cash all or part of the Notes if the last reported sale price of the Company’s common stock equals or exceeds 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of the redemption. The redemption price will be 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any. No sinking fund is provided for the Notes.

Upon the occurrence of a fundamental change (as defined in the Indenture), holders may require the Company to repurchase all or a portion of their Notes for cash at a price equal to 100% of the principal amount of the Notes to be repurchased plus any accrued but unpaid interest to, but excluding, the fundamental change repurchase date.

In accounting for the issuance of the Notes, the Company separated the Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component, representing the conversion option, which does not meet the criteria for separate accounting as a derivative as it is indexed to the Company's own stock, was determined by deducting the fair value of the liability component from the par value of the Notes. The difference between the principal amount of the Notes and the liability component represents the debt discount, which is recorded as a direct deduction from the related debt liability in the Consolidated Balance Sheet and amortized to interest expense using the effective interest method over the term of the Notes. The effective interest rate of the Notes is 15.3% per annum. The equity component of the Notes is approximately $39.5 million, net of allocated issuance costs of $1.5 million. This is included in additional paid-in capital in the Consolidated Balance Sheet, net of deferred tax impacts of $9.7 million, and is not remeasured as long as it continues to meet the conditions for equity classification. The Company allocated transaction costs related to the Notes using the same proportions as the proceeds from the Notes. Transaction costs attributable to the liability component were recorded as a direct deduction from the related debt liability in the Consolidated Balance Sheet and amortized to interest expense over the term of the Notes, and transaction costs attributable to the equity component were netted with the equity component in shareholders’ equity.

In addition, the Company determined that the additional interest that could be due to the holders of the Notes upon an event of default or non-timely filing represented an embedded derivative feature that should be bifurcated from the Notes. The Company concluded that the fair value of this embedded derivative feature was de minimis upon the issuance of the Notes and at December 31, 2020.

During the years ended December 31, 2020 and 2019, no portion of the Notes was converted and the liability component was classified as long-term debt on the Company's Consolidated Balance Sheet as of December 31, 2020.

The following table summarizes the net carrying amount of the Notes as of December 31, 2020 (in thousands):

	December 31, 2020		December 31, 2019
Principal amount of the Notes	$	86,250	$	86,250
Unamortized debt discount	(37,791)		(40,902)

Interest expense related to contractual coupon interest	$	3,234	$	925
Interest expense related to amortization of the debt discount1	3,111		1,744
Total interest expense	$	6,345	$	2,669

1 Refer to Note 1. Summary of Significant Accounting Policies relating to an immaterial out of period error correction of non-cash interest identified and recorded during the fourth fiscal quarter of 2020.

As of December 31, 2020, the remaining period over which the unamortized discount will be amortized is 68.5 months.

The estimated fair value of the Notes was $156.9 million as of December 31, 2020, determined through consideration of quoted market prices in less active markets. The fair value measurement is classified as Level 2 in the fair value hierarchy, which is defined in ASC 820 as inputs other than quoted prices in active markets that are either directly or indirectly observable. Based on our closing stock price of $145.65 on December 31, 2020, the if-converted value exceeded the aggregate principal amount of the Notes by $58.8 million.

The carrying value of the note receivable, included in Related party convertible note receivable, net on the Consolidated Balance Sheets, is as follows (in thousands):

	December 31, 2020
Principal amount	$	6,650
Unamortized discount	(977)
Net carrying amount	$	5,673

On December 9, 2020, our equity method investee (the “Investee”), issued a Convertible Promissory Note to the Company (the “Convertible Promissory Note”) with a principal amount of $6.65 million and a stated interest rate of 3.0% per annum that is payable monthly. The Convertible Promissory Note has a maturity date of December 9, 2023, or otherwise upon qualified redemption event or in the event of a default. Refer to Note 4 for additional information on our equity method investment.

The conversion of the Convertible Promissory Note is contingent upon certain events. Due to the convertible debt features included in the Convertible Promissory Note, it is not an equity security and is therefore not considered an additional investment in our equity method investee. The Company accounted for the transaction as a note receivable, included in Related party convertible note receivable, net on the Consolidated Balance Sheets. The note receivable will be measured at amortized cost, and evaluated for credit losses each reporting period. The Company determined that the redemption features described above met the definition of an embedded derivative that requires bifurcation from the note receivable host. The Company measured the redemption features at fair value, with the residual proceeds paid allocated to the note receivable host, creating a discount to the note receivable. The discount will be amortized over the contractual term of the Promissory Note using the effective interest method. The effective interest rate of the Convertible Promissory Note is 8.69%, and the amortization of the discount will be included as interest income within Interest and other expense (income), net on the Consolidated Statements of Income.

The fair value of the embedded derivative was $1.0 million at issuance and as of December 31, 2020, and is included in Related party convertible note receivable, net on our Consolidated Balance Sheets. The fair value of the derivative will be remeasured each reporting period, with the mark-to-market adjustment to be included in other expense (income) on the Consolidated Statements of Income.

Segment Reporting [Abstract]

SEGMENT REPORTING

SEGMENT REPORTING

On April 1, 2020, Heska completed the acquisition of scil. Following this acquisition, the Company restructured its operating segments based on how the Chief Operating Decision Maker (“CODM”) manages the business, allocates resources, makes operating decisions and evaluates operating performance. The CODM changed how he assesses performance and allocates resources based on geographic regions in order to better align with the global operations of the Company. Based on this change, the Company determined it has two reportable segments and revised prior comparative periods to conform to the current period segment presentation. The Company’s two segments are North America and International.

The North America segment is comprised of the Company's operations in the United States, Canada and Mexico and the International segment is comprised of geographies outside of North America, which are the Company's operations primarily in Australia, France, Germany, Italy, Malaysia, Spain and Switzerland. Certain expenses incurred at the Company’s headquarters located in the North America segment are allocated to each segment in a manner consistent with where the benefits from the expenses are derived. However, there

are certain corporate expenses included in the North America segment that we do not allocate. Such expenses include research and development, certain selling, marketing, general, and administrative costs that support the global organization. Sales and transfers between operating segments are accounted for at market-based transaction prices and are eliminated in consolidation. The Company's sales are determined by the country of origin where the sale occurred. For a description of Heska's previous operating segments, refer to Note 17 to the consolidated financial statements included in Part II. Item 8 of Heska's Annual Report on Form 10-K for the year ended December 31, 2019.

Our CODM continues to evaluate segment performance and allocate resources based on Revenue, Cost of Revenue, Gross Profit, Gross Margin and Operating Income. The CODM does not evaluate operating segments using asset information; however, we have included total asset information by segment below as there was a material change in total assets by segment as of December 31, 2020 due to the acquisition of scil.

SUBSEQUENT EVENTS

Lacuna Diagnostics, Inc.

On February 1, 2021 the Company completed the acquisition of Lacuna Diagnostics, Inc. ("Lacuna"), a veterinary digital cytology company, to broaden the Company's point of care diagnostic offering. In exchange for all the outstanding shares of Lacuna, the Company paid total consideration of $4.3 million upon closing. The Company expects to account for this transaction as a business combination however, does not have that accounting complete as of the date of this filing due to the limited time that has passed since the date of transaction.

As additional consideration for the shares, the Company agreed to a contingent earn-out of an additional $2 million based on the achievement of certain performance metrics within a twelve month period ("Initial Earn Out Period"), reducing to $1 million if such metrics were met in a twelve month period subsequent to the Initial Earn Out Period.

Note Receivable

On February 1, 2021, one of our equity investees ("Investee"), for which we account for as a nonmarketable equity security, issued a Promissory Note to the Company (the “Promissory Note”) with a principal amount of $9.0 million and a stated interest rate of 10.0% per annum that is payable monthly. The Promissory Note has a maturity date of December 1, 2024. The Promissory Note provides for interest only payments through December 1, 2023. Beginning on January 1, 2024, the Promissory Note requires repayment of the principal and interest over twelve consecutive monthly payments.

OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2020

Accounting Policies [Abstract]

Basis of Presentation and Consolidation

In the opinion of management, the accompanying Consolidated Financial Statements contain all adjustments, consisting of normal, recurring adjustments, necessary to present fairly the financial position of the Company as of December 31, 2020 and 2019, as well as the results of our operations, statements of stockholders' equity and cash flows for the twelve months ended December 31, 2020, 2019 and 2018.

The audited Consolidated Financial Statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Our audited 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 loss attributable to non-controlling interest" on our Consolidated Statements of (Loss) Income. Our audited Consolidated Financial Statements are stated in U.S. Dollars and have been prepared in accordance with accounting principles generally accepted in the U.S. ("GAAP").

Beginning in the first quarter of 2020, to limit the spread of COVID-19, governments took various actions including the issuance of stay-at-home policies and social distancing procedures and guidelines, causing some businesses to adjust, reduce or suspend business and operating activities. Veterinary care is widely recognized as an "essential" service for pet owners, and veterinarians continued to deliver essential medical care for sick and injured pets. The stay-at-home policies deployed early in 2020 to combat the spread of COVID-19 resulted in a decrease in companion animal clinical visits, including delay of elective procedures and wellness visits and as a result lowers demand for diagnostic testing services. Beginning in the second quarter of 2020, certain local, state and federal governments began to ease the stay-at-home policies and allowed more businesses and facilities to re-open, leading to a recovery in companion animal clinical visits and associated demand for our diagnostic products. The extent to which the continuation, or a possible second-wave outbreak of COVID-19, or an outbreak of other health epidemics could impact our business, results of operations and financial condition, including the potential for write-offs or impairments of assets and suspension of capital investments, will depend on future developments. We are unable to predict with certainty the effects of the COVID-19 pandemic on our customers, suppliers and vendors, as well as the actions of governments, and when and to what extent normal economic and operating conditions can resume; these effects may differ from those assumed in our projected estimates. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business as a result of any economic impact that has occurred or may occur in the future.

Use of Estimates

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 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 net realizable value of inventory; determining future costs associated with warranties provided; 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 and investments for estimated useful lives and impairment; estimating the useful lives and standalone selling prices of instruments under leasing arrangements; determining the allocation of purchase price under purchase accounting; estimating the expense associated with the granting of stock; determining the need for, and the amount of a valuation allowance on deferred tax assets; determining the fair value of our embedded derivative; and determining the fair value of the liability component associated with the issuance of convertible debt. Our actual results may differ from these estimates and there may be changes to those estimates in future periods.

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 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.

Covetrus represented 9% and 19% of our consolidated accounts receivable at December 31, 2020 and 2019, respectively. No other customer accounted for more than 10% of our consolidated accounts receivable at December 31, 2020 or 2019.

We have established an allowance for credit losses 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 net of an allowance for credit losses. From time to time, our customers are unable to meet their payment obligations. We continuously monitor our customers' credit worthiness and establish allowances for estimated credit losses related to our accounts receivable, net investment in leases, contract assets, and promissory notes. Our allowances are established based on factors surrounding the credit risk of specific customers, historical experience including collections and write-off history, and current economic conditions. Account balances are considered past due if payments have not been received within agreed upon invoice and/or contract terms and the Company may employ collection agencies and legal counsel to pursue recovery of defaulted amounts. Account balances are written off against the allowance after all collection efforts have been exhausted and it is probable the receivable will not be recovered. The Company also performs a qualitative assessment, on a quarterly basis, to monitor economic factors and other uncertainties that may require additional adjustments for the expected credit loss allowance. 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. The Company will continue to actively monitor the impact of the COVID-19 pandemic on expected credit losses. In 2020, the Company adopted Accounting Standards Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326). See "Adoption of New Accounting Standards" below for impacts of adoption.

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.

Fair Value of Financial Instruments

The Company's financial instruments consist of cash and cash equivalents, short-term trade receivables and payables, a long-term note receivable with an embedded derivative asset, and its 3.75% Convertible Senior Notes due 2026 (the "Notes"). 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.

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 (Loss) 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 43 years
Machinery and equipment	2 to 10 years
Office furniture and equipment	3 to 7 years
Computer hardware and software	3 to 7 years
Leasehold and building improvements	5 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 seven 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.

Investments in Unconsolidated Affiliates

Investments in unconsolidated affiliates are measured and recorded as either non-marketable equity securities or equity method investments. Non-marketable equity securities are equity securities without readily determinable fair value that are measured and recorded using a measurement alternative which measures the securities at cost minus impairment, if any, plus or minus changes from qualifying observable price changes. Equity method investments are equity securities in investees we do not control but over which we have the ability to exercise significant influence. When the equity method of accounting is determined to be appropriate, the initial measurement of the investment includes the cost of the investment and all direct transaction costs incurred to acquire the investment. Equity method investments are measured at cost minus impairment, if any, plus or minus our share of equity method investee income or loss, which is recorded as a separate line on the income statement. Both types of investments are evaluated for impairment if a triggering event occurs.

Goodwill, Intangible and Other Long-Lived Assets

Goodwill is initially valued based on the excess of the purchase price of a business combination over the fair value of acquired net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Intangible assets other than goodwill are initially valued at fair value. If a quoted price in an active market for the identical asset is not readily available at the measurement date, the fair value of the intangible asset is estimated based on discounted cash flows using market participant assumptions, which are assumptions that are not specific to the Company. The selection of appropriate valuation methodologies and the estimation of discounted cash flows require significant assumptions about the timing and amounts of future cash flows, risks, appropriate discount rates, and the useful lives of intangible assets. When material, we utilize independent valuation experts to advise and assist us in determining the fair values of the identified intangible assets acquired in connection with a business acquisition and in determining appropriate amortization methods and periods for those intangible 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 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 it is 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. Following the acquisition of scil in April 2020, we restructured our operating segments based on how the Chief Operating Decision Maker (“CODM”) manages the business, allocates resources, makes operating decisions and evaluates operating performance. As further discussed in Note 18, our new reporting segments are North America and International. As a result of the change in operating segments, we also revised our reporting units to aggregate our legal entities based on similarities in economic characteristics. Our new reporting units consist of the following: (1) Heska Corporation and Heska Canada, (2) Diamond Animal Health, (3) scil animal care company GmbH, Optomed, CVM, and Heska Australia, and (4) Heska AG.

As a result of the recent global economic disruption and uncertainty due to the COVID-19 pandemic, the

Company performed a qualitative assessment during the first quarter of 2020. Based on the interim assessment performed, we concluded that there was no triggering event and additionally, no indications of impairment existed. We performed qualitative assessments in the fourth quarters of 2020, 2019, and 2018 and determined that no indications of impairment existed. We assess the realizability of intangible assets other than goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If an impairment review is triggered, we evaluate the carrying value of intangible assets based on estimated undiscounted future cash flows over the remaining useful life of the primary asset of the asset group and compare that value to the carrying value of the asset group. The cash flows that are used contain our best estimates, using appropriate and customary assumptions and projections at the time. If the net carrying value of an intangible asset exceeds the related estimated undiscounted future cash flows, an impairment to adjust the intangible asset to its fair value would be reported as a non-cash charge to earnings. If necessary, we would calculate the fair value of an intangible asset using the present value of the estimated future cash flows to be generated by the intangible asset, and applying a risk-adjusted discount rate.

Revenue Recognition

We generate revenue through the sale of products, either by outright purchase by our customers or through a subscription agreement whereby our customers receive instruments and pay us a monthly fee for the consumables needed to conduct testing. Subscription placement is the majority of our Point of Care laboratory transactions while outright sales to customers are the majority of both Point of Care imaging diagnostic transactions and the sale of pharmaceuticals and vaccines.

For outright sales of products, revenue is recognized when control of the promised product or service is transferred to our customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those products or services (the transaction price). Taxes assessed by governmental authorities and collected from the customer are excluded from our revenue recognition. A performance obligation is a promise in a contract to transfer a distinct product or service to a customer and is the unit of account under ASC 606. For instruments, consumables and most software licenses sold by the Company, control transfers to the customer at a point in time. To indicate the transfer of control, the Company must have a present right to payment, legal title must have passed to the customer, the customer must have the significant risks and rewards of ownership and where acceptance is not a formality, the customer must have accepted the product or service. Heska’s principal terms of sale are FOB Shipping Point, or equivalent, and, as such, we primarily transfer control and record revenue for product sales upon shipment. If a performance obligation to the customer with respect to a sales transaction remains unfulfilled following shipment (typically owed installation), revenue recognition for that performance obligation is deferred until such commitments have been fulfilled. For extended warranty and service plans, control transfers to the customer over the term of the arrangement and as such the revenue is recognized ratably based upon the period of time elapsed under the arrangement.

Our revenue under subscription agreements relates to operating-type lease ("OTL") arrangements or sales-type lease ("STL") arrangements. Determination of an OTL or STL is primarily determined as a result of the length of the contract as compared to the estimated useful life of the instrument, among other factors. Leases are outside of the scope of ASC 606 and are therefore accounted for in accordance with ASC 842, Leases. A STL would result in earlier recognition of instrument revenue as compared to an OTL, which is generally upon installation of the instruments. Instrument lease revenue for our OTL subscription agreements is recognized on a straight-line basis over the life of the lease and is included with the predominant non-lease components in consumables revenue. For instrument only OTL agreements, operating lease income is

recognized on a straight-line basis over the term of the lease. The cash collected under both arrangements is over the term of the contract. The OTLs and STLs are not cancellable until after an initial term. See below for additional information on our lease accounting policies.

For contracts with both lease and non-lease components, the Company allocates the contracts' transaction price for each component on a relative standalone selling price basis using our best estimate of the standalone selling price of each distinct product or service in the contract. When available, the method used to estimate the standalone selling price is the price observed in standalone sales to customers. When prices in standalone sales are not available, we use a cost-plus margin approach. Changes in these values can impact the amount of consideration allocated to each component of the contract. Allocation of the transaction price is determined at the contracts' inception. The Company does not adjust the transaction price for the effects of a significant financing component when the period between the transfer of the promised good or service to the customer and payment for that good or service by the customer is expected to be one year or less.

To the extent the transaction price includes variable consideration, such as future payments based on consumable usage over time, we apply judgment to determine if the variable consideration should be constrained. As the variable consideration is highly susceptible to factors outside of the Company’s influence, and the potential values contain a broad range of possible outcomes given all potential amounts of consumption that could occur, it is likely that a significant revenue reversal would occur should the variable consideration be estimated at an amount greater than the minimum stated amount until such a time as the uncertainty is resolved. For our subscription agreements with variable consideration based on consumable usage over time, the variable consideration is allocated to the non-lease components upon resolution of the uncertainty and is included in consumables revenue.

We generate OVP revenue through contract manufacturing agreements with customers. Revenue from these customer contracts is generally recognized upon shipment or acceptance by our customer, under the same guidelines noted above for other outright product sales. Heska assessed the over-time criteria within ASC 606 and concluded that while 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. Therefore, point in time revenue recognition has been determined to be appropriate.

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 and intent to make payments in accordance with arrangements. For contracts with multiple performance obligations, we exercise judgment in allocating the transaction price for each performance obligation based on an estimated standalone selling price for each distinct product or service. We do not generally allow return of products or instruments. Distributor rebates are recorded as a reduction to revenue.

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 requisite service period of the award generally using the straight-line method.

Advertising Costs

Advertising costs are expensed as incurred and are included in sales and marketing expenses.

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 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 certain foreign subsidiaries is the local currency. Accordingly, assets and liabilities of these subsidiaries 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. Gains and losses arising from intercompany foreign currency transactions that are of a long-term investment nature are reported as a component of Accumulated other comprehensive income in the Consolidated Balance Sheets.

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. Extended warranties are sold to our customers and revenue is recognized over the term of the warranty agreement, as expected costs are incurred.

Recent Accounting Pronouncements

Adoption of New Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326), which requires 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. Subsequent to the issuance of ASU 2016-13, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, in November 2018. This ASU clarifies that receivables from operating leases are accounted for using the lease guidance and not as financial instruments. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, which further clarifies and improves guidance related to accounting for credit losses. In May 2019, the FASB issued ASU 2019-05, Financial Instruments - Credit Losses (Topic 326). This ASU provides relief to certain entities adopting ASU 2016-13. The amendment provides entities with an option to irrevocably elect the fair value option for certain financial assets. The Company adopted ASU 2016-13 with a cumulative-effect adjustment in retained earnings as of January 1, 2020. The impact of the adoption was not material to the Company's consolidated financial statements.

Accounting Pronouncements Not Yet Adopted    

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to the accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740, and also clarifies and amends existing guidance to improve consistent application. This guidance will be effective for interim and annual periods beginning after December 15, 2020, and early adoption is permitted. We evaluated the impact of the standard on our consolidated financial statements and do not expect the standard to have a material impact on our consolidated financial statements and disclosures.

In January 2020, the FASB issued ASU 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815). The amendments in this ASU clarify the interaction between the accounting for investments in equity securities, investment in equity method and certain derivatives instruments. The ASU is expected to reduce diversity in practice and increase comparability of the accounting for these interactions. This guidance will be effective for fiscal years beginning after December 15, 2020. We evaluated the impact of the standard on our consolidated financial statements and do not expect the standard to have a material impact on our consolidated financial statements and disclosures.

In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40), which simplifies the accounting for certain convertible instruments. The update reduces the number of accounting models for convertible debt instruments and convertible preferred stock. Convertible debt will be accounted for as a single liability measured at its amortized cost and convertible preferred stock will be accounted for as a single equity instrument measured at its historical cost, as long as no other features require bifurcation and recognition as derivatives. The update also requires the if-converted method to be used for convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. The guidance may be early adopted for fiscal years beginning after December 15, 2020,

and interim periods within those fiscal years.

The Company has elected to early adopt ASU 2020-06 as of January 1, 2021. The Notes are a convertible instrument with a cash-conversion feature that is accounted for within the scope of ASC 470-20 and will be impacted by adopting ASU 2020-06. The Company has elected to apply the modified retrospective method wherein the Company will recognize a cumulative-effect adjustment to the opening balance of retained earnings (January 1, 2021). Further, the Company will not restate EPS in the prior periods. The Company calculated the cumulative-effect adjustment as of January 1, 2021 by comparing (i) the historical amortization schedule for the Notes through December 31, 2020 and (ii) an updated amortization schedule wherein the conversion feature within the Notes would not be separated as an equity component and subsequently recognized as non-cash interest expense under ASC 835-30. As a result of ASU 2020-06, while cash interest expense is not impacted, non-cash interest accretion is limited to the amortization of debt issuance costs under ASC 835-30. Therefore, the Company prepared its transition journal entries by (i) reversing the conversion feature amount recorded in APIC and (ii) reversing the difference in non-cash interest expense via retained earnings. The expected impact on retained earnings is $4.3 million.

In October 2020, the FASB issued ASU 2020-10, Codification Improvements, which updates various codification topics by clarifying or improving disclosure requirements to align with the SEC's regulations. This guidance will be effective for annual periods beginning after December 15, 2020, for public entities. The Company will adopt as of the reporting period beginning January 1, 2021. We evaluated the impact of the

standard on our consolidated financial statements and do not expect the standard to have a material impact on our consolidated financial statements and disclosures.

Reclassification, Comparability Adjustment

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

Lessee, Leases

The Company acts as a lessee and a lessor. As a lessee, the Company leases buildings, office equipment, and vehicles. As a lessor, the Company enters into sales-type and operating leases as part of its subscription agreements.

The Company determines if an arrangement is a lease at inception based on whether control of an identified asset is transferred. For leases where the Company is the lessee, ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based

on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit interest rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as amortization expense and interest expense. The Company has lease agreements which require payments for lease and non-lease components and has elected to account for these as a single lease component for our building and office equipment leases, but as separate components for our vehicle leases.

As a lessor, our subscription agreements relate to both OTL arrangements and STL arrangements. For a STL, instrument revenue is generally recorded upon installation of the instruments and the cost of the customer-leased instruments is removed from inventory and recognized in the Consolidated Statements of (Loss) Income. There is no residual value taken into consideration as it does not meet our capitalization requirements. For our OTL agreements that include both lease and non-lease components, revenue is recognized on a straight-line basis over the term of the lease and is included with the predominant non-lease components in consumables revenue. For instrument only OTL agreements, operating lease income is recognized on a straight-line basis over the term of the lease. For an OTL, the costs of customer-leased instruments are recorded within property and equipment in the accompanying Consolidated Balance Sheets and depreciated over the instrument’s estimated useful life. The depreciation expense is reflected in cost of revenue in the accompanying Consolidated Statements of (Loss) Income.

For leases that commenced before the January 1, 2019 effective date of ASC 842, the Company elected the permitted practical expedients to not reassess the following: (i) whether any expired or existing contracts contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases. The Company also elected to exclude leases with a term of 12 months or less from the recognized ROU assets and lease liabilities.
