Item 1A. Risk Factors.

Risks Relating to Our Business

Our business involves a variety of risks and uncertainties, known and unknown, including, among others, the risks discussed below. These risks should be carefully considered together with the other information provided in this Annual Report on Form 10-K and in our other filings with the SEC. Our failure to adequately anticipate or address these risks and uncertainties may have a material, adverse impact on our business, reputation, revenues, financial condition, profitability, and cash flows. Additional risks and uncertainties not presently known or knowable to us, or that we currently believe to be immaterial, may also adversely affect our business.

Business and Economic Risks

COVID-19, and similar public health crises, could have a material, adverse impact on us.

Since early 2020, businesses, communities, and governments worldwide have taken, and continue to take, a wide range of actions to mitigate the spread and impact of COVID-19, leading to an unprecedented impact on the global economy. We continue to be subject to risks related to the COVID-19 pandemic, and risks that may result from future pandemics, epidemics, or other public health crises. The nature and extent of these risks are highly uncertain and unpredictable and may vary greatly by region. Although many countries and hospitals have seen a decline in cases, and thus, many countries, businesses, and hospitals, including ourselves, have begun to remove or reduce COVID-19 related restrictions, the potential for additional or renewed impact or related fallout from new variants or local outbreaks of COVID-19 remains, particularly in light of the enhanced exposure risks faced by our customers and their workforces. Risks related to COVID-19 and other public health crises have and could continue to impact our activities in a number of ways, including by impacting:

•Our product sales. Local lockdowns, capacity constraints on healthcare systems, residual shortages in hospital staffing, and other factors resulting from COVID-19 and similar public health crises have and could impact our revenue. These crises can cause a reduction in demand for certain products and services due to factors such as reduced elective and non-emergency procedure volumes, healthcare worker shortages, changes in hospital utilization rates, reduced sales force access to hospitals, and reduced customer spending. In addition to COVID-19’s impact on demand and procedure volumes, we have observed downstream financial effects from the pandemic, including an increase in delays or difficulty in collecting outstanding receivables, particularly with governmental payors in regions heavily impacted by COVID-19 and the related macroeconomic fallout.

•Our business operations. COVID-19 and similar public health crises present the potential to impact our workforce availability and that of our business partners. We have observed this risk with our customers and suppliers, which can impact operations, and also with certain regulators and Notified Bodies that we rely on, which in turn increases the risks we face with respect to timely review and approval of new and renewal regulatory approvals for our products.

•Our manufacturing operations. The COVID-19 pandemic and the related macroeconomic fallout has continued to impact the global supply chain; the impact on workforces, material availability, demand, and costs has reportedly continued or worsened in many cases. Although we have yet to experience any material effects on our supply chain, we have faced increasing costs and face an increasing risk that upstream disruptions may occur. Risks relating to the lingering effects of global supply chain disruptions may continue even after COVID-19’s risk as a global pandemic has subsided.

•Our workforce. As some global economies have begun to emerge from the COVID-19 downturn, increased opportunities for remote work, the Great Resignation, and increasing compensation pressure have resulted in a competition for talent at all levels and an unprecedented number of career changes. The resulting worker shortages and increased labor costs have impacted supply chains, distribution channels, and employers’ ability to adequately staff their operations. While the effect appears to be waning somewhat, this has impacted not only our own ability to attract and retain employees, but also the ability of our customers who face increasing staffing pressures throughout their healthcare organizations.

•Our research and development projects. COVID-19 and similar public crises have impacted and can impact our R&D projects, including by impacting the timelines for our clinical research projects and the timing of and need for spending. Enrollment and timelines for our clinical trials have been, and might continue to be, impacted as healthcare providers re-prioritize resources, address staffing shortages, and limit access to healthcare facilities.

The extent to which COVID-19, its variants, or any future public health crises impact our operations or our recovery from the impact of COVID-19, will depend largely on future developments that are highly uncertain and unpredictable and may vary greatly by region. This impact and any such adverse developments or prolonged periods of uncertainty could adversely affect our financial performance.

We are subject to a variety of risks due to our international operations and continued global expansion.

Our international operations subject us to a number of risks, which may vary significantly from the risks we face in our US operations, including:

•Greater difficulties and costs associated with staffing (at all levels), establishing and maintaining internal controls, managing foreign operations and distributor relationships, and selling directly to customers;

•Broader exposure to corruption and expanded compliance obligations, including under the Foreign Corrupt Practices Act, the UK Bribery Law, local anti-corruption laws, Office of Foreign Asset Control administered sanction programs, the European Union’s General Data Protection Regulation, and other emerging corruption and data privacy regulations;

•Overlapping and potentially conflicting, or unexpected changes in, international legal and regulatory requirements or reimbursement policies and programs;

•Longer and more expensive collection cycles in certain countries, particularly those in which our primary customers are government-funded hospitals;

•Changes in currency exchange rates, particularly fluctuations in the Euro as compared to the US Dollar and inflationary pressures in Latin America;

•Potential adverse financial impact and negative erosion of our operating profit margin over time due to increasing inflationary pressures, particularly impacting our Latin American business as well as impact felt through our supply chain; our exposure may be increased through our limited ability to raise prices and through global expansion where business occurs with, or pricing is set directly by, government entities, or we are party to long term pricing agreements with governments or local distributors, impacting our ability to pass on rising costs;

•Potential adverse tax consequences of overlapping tax structures or potential changes in domestic and international tax policy, laws, and treaties; and

•Potential adverse financial and regulatory consequences resulting from Brexit.

Our operations and performance have been and may continue to be impacted by regional and global geopolitical conditions, domestic and foreign trade and monetary policies, and other factors beyond our control. As an example of these risks, Russia’s military attacks on Ukraine have triggered significant sanctions from the US and foreign governments and retaliatory actions from Russia, resulting in significant banking and trade disruptions. The war has also resulted in significant devastation to the people and infrastructure in the region, significantly impacting trade and transportation which may impact our global supply chain, increase prices, and limit our ability to continue to do business in affected regions.

To date, sanctions and other disruptions in the region have not materially impacted our business or ability to supply products to Russia, Belarus, Ukraine, and the region generally; however, continuation or escalation of the war or increased export controls or additional sanctions imposed on or by Russia, its allies, or related entities could adversely affect our financial performance. Although we do not have any direct operations in Russia or Ukraine, it is difficult to predict the ultimate course of the war and we may face business operations and supply chain disruptions as a result, including disruptions related to shortages of materials, higher costs of materials and freight, freight delays, increased energy costs or energy shortages, travel disruptions, currency fluctuation, and disruptions to banking systems or capital markets.

We operate in highly competitive market segments, face competition from large, well-established medical device companies and tissue service providers with greater resources and we may not be able to compete effectively.

The market for our products and services is competitive and affected by new product introductions and activities of other industry participants. We face intense competition in virtually all of our product lines. A significant percentage of market revenues from competitive products are generated by Baxter, Ethicon (a Johnson & Johnson Company), Medtronic, plc, Abbott Laboratories, Edwards Lifesciences Corp., C.R. Bard, Inc., a subsidiary of Becton, Dickinson and Company, Integra Life Sciences Holdings, LifeNet, Corcym, Anteris Technologies, Inc., Aziyo Biologics, Cook Medical, Gore & Associates, Terumo, LeMaitre Vascular, Inc., Maquet, Inc., Pfizer, Inc., and BioCer Entwicklungs-GmbH. Several of our competitors enjoy competitive advantages over us, including:

•Greater financial and other resources for research and development, commercialization, acquisitions, and litigation and to weather the impacts of COVID-19 and increased workforce competition;

•Greater name recognition as well as more recognizable trademarks for products similar to products that we sell;

•More established record of obtaining and maintaining regulatory product clearances or approvals;

•More established relationships with healthcare providers and payors;

•Lower cost of goods sold or preservation costs; and

•Larger direct sales forces and more established distribution networks.

We are significantly dependent on our revenues from tissue preservation services and are subject to a variety of risks affecting them.

Tissue preservation services are a significant source of our revenues, and as such, we face risks if we are unable to:

•Source sufficient quantities of some human tissue or address potential excess supply of others. We rely primarily upon the efforts of third parties to educate the public and foster a willingness to donate tissue. Factors beyond our control such as supply, regulatory changes, negative publicity concerning methods of tissue recovery or disease transmission from donated tissue, or public opinion of the donor process as well as our own reputation in the industry can negatively impact the supply of tissue;

•Compete effectively, as we may be unable to capitalize on our clinical advantages or our competitors may have advantages over us in terms of cost structure, pricing, back-office automation, marketing, and sourcing; or

•Mitigate sufficiently the risk that tissue can become contaminated during processing; that processed tissue cannot be end-sterilized and hence carries an inherent risk of infection or disease transmission or that our quality controls can eliminate that risk.

As an example of these risks, in the fourth quarter of 2020 we became aware that a supplier shipped to us a lot of saline solution that we use in our tissue processing that contained some contamination. The contamination was identified by our routine quality controls. While we were able to mitigate the impact of this contamination through our own efforts and additional testing that was reviewed with the FDA, the contaminated solution impacted a small percentage of the tissue processed with this lot of solution, requiring us to write-off approximately $826,000 in contaminated tissues in the fourth quarter of 2020. The written off and temporarily quarantined tissue impacted our ability to fully meet demand for certain tissues and sizes in the fourth quarter of 2020, the first quarter of 2021, and to a lesser extent the second quarter of 2021. See also, Part I, Item 1A, “Risk Factors—Operational Risks— We are dependent on our specialized workforce.”

In addition, US and foreign governmental authorities have adopted laws and regulations that restrict tissue preservation services. Any of these laws or regulations could change, including becoming more restrictive or our interpretation of them could be challenged by governmental authorities.

We are significantly dependent on our revenues from BioGlue and are subject to a variety of related risks.

BioGlue is a significant source of our revenues, and as such, any risk adversely affecting our BioGlue products or business would likely be material to our financial results. We face the following risks related to BioGlue:

•Competing effectively with our major and start up competitors, as they may have advantages over us in terms of cost structure, supply chain, pricing, sales force footprint, and brand recognition;

•We may be unable to obtain approval to commercialize BioGlue in certain non-US countries as fast as our competitors do of their products or at all. We also may not be able to capitalize on new BioGlue approvals, including for new indications, in non-US countries; and

Table of Contents

•BioGlue contains a bovine blood protein. Animal-based products are subject to increased scrutiny from the public and regulators, who may seek to impose additional regulations, regulatory hurdles or product bans in certain countries on such products; BioGlue is a mature product and other companies may use the inventions disclosed in expired BioGlue patents to develop and make competing products.

We are significantly dependent on our revenues from aortic stent grafts and are subject to a variety of related risks.

Aortic stent grafts are a significant source of our revenues, and as such, any risk adversely affecting aortic stent grafts would likely be material to our financial results. We face risks related to aortic stent grafts based on our ability to:

•Compete effectively with some of our major competitors, as they may have advantages over us in terms of cost structure, supply chain, pricing, sales force footprint, and brand recognition;

•Develop innovative, high quality, and in-demand aortic repair products;

•Respond adequately to enhanced regulatory requirements and enforcement activities, and particularly, our ability to obtain regulatory approvals and renewals globally;

•Meet demand for aortic stent grafts as we seek to expand our business globally; and

•Maintain a productive working relationship with our Works Council in Germany.

We are significantly dependent on our revenues from On-X products and are subject to a variety of related risks.

On-X products are a significant source of our revenues, and as such, any risk adversely affecting our On-X products or business would likely be material to our financial results. We face risks based on our ability to:

•Compete effectively with some of our major competitors, as they may have advantages over us in terms of cost structure, supply chain, pricing, sales force footprint, and brand recognition;

•Take market share in the mechanical heart valve market based on the FDA’s approved lower INR indication for the On-X aortic heart valve or complete the associated FDA mandated post-approval studies;

•Address clinical trial data or changes in technology that may reduce the demand for mechanical heart valves, such as data regarding transcatheter aortic valve replacement, or “TAVR” devices;

•Manage risks associated with less favorable contract terms for On-X products on consignment at hospitals;

•Respond adequately to enhanced international regulatory requirements or enforcement activities; and

•Receive timely renewal certifications in certain markets.

Continued fluctuation of foreign currencies relative to the US Dollar could materially, adversely affect our business.

The majority of our foreign product revenues are denominated in Euros and, as such, are sensitive to changes in exchange rates. In addition, a portion of our dollar-denominated and euro-denominated product sales are made to customers in other countries who must convert local currencies into US Dollars or Euros in order to purchase these products. We also have balances, such as cash, accounts receivable, accounts payable, and accruals that are denominated in foreign currencies. These foreign currency transactions and balances are sensitive to changes in exchange rates. Additionally, as a result of global inflationary pressures, and in some cases, currency crises, it is possible that foreign currency controls, the development of parallel exchange rates, or highly inflationary economies could arise in certain countries. Fluctuations in exchange rates of Euros or other local currencies in relation to the US Dollar could materially reduce our future revenues as compared to the comparable prior periods. Should this occur, it could have a material, adverse impact on our revenues, financial condition, profitability, and cash flows.

Our charges resulting from acquisitions, restructurings, and integrations may materially, adversely affect the market value of our common stock.

We account for the completion of acquisitions using the purchase method of accounting. Our financial results could be adversely affected by a number of financial adjustments required by purchase accounting such as:

•We may incur added amortization expense over the estimated useful lives of some acquired intangible assets;

•We may incur additional depreciation expense as a result of recording purchased tangible assets;

•We may be required to incur material charges relating to any impairment of goodwill and intangible assets;

•Cost of sales may increase temporarily if acquired inventory is recorded at fair market value;

Table of Contents

•If acquisition consideration consists of earn-outs, our earnings may be affected by changes in estimates of future contingent consideration; or

•Earnings may be affected by transaction and integration costs, which are expensed immediately.

As an example of this risk, in the fourth quarter of 2021, we fully impaired the value of a securities purchase option agreement with Endospan (“Endospan Option”) and fully wrote-down the value of an agreement for a secured loan from Artivion to Endospan (“Endospan Loan”), primarily driven by a decrease in forecasted operating results. This impairment, and other potential risks like those mentioned above, may adversely affect the market value of our common stock.

Operational Risks

We are heavily dependent on our suppliers and contract manufacturers to provide quality products.

The materials and supplies used in our product manufacturing and tissue processing are subject to regulatory requirements and oversight. If materials or supplies used in our processes fail to meet these requirements or are subject to regulatory enforcement action, they may have to be scrapped, or our products or tissues could be rejected during or after processing, recalled, or rejected by customers. In these cases, we may have to immediately scrap raw or in-process materials or expense the costs of manufacturing or preservation.

As an example of this risk, in the fourth quarter of 2020 we became aware that a supplier shipped to us a lot of saline solution that we use in our tissue processing that contained some contamination. The contamination was identified by our routine quality controls. While we were able to mitigate the impact of this contamination through our own efforts and additional testing that was reviewed with the FDA, the contaminated solution impacted a small percentage of the tissue processed with this lot of solution, requiring us to write-off those contaminated tissues in the fourth quarter of 2020 and impacting our ability to fully meet demand for certain tissues and sizes in the fourth quarter of 2020, the first quarter of 2021, and to a lesser extent the second quarter of 2021.

In addition, if these materials or supplies, or changes to them, do not receive regulatory approval or are recalled, if the related suppliers and/or their facilities are shut down temporarily or permanently, for any reason, or if the related suppliers are otherwise unable or unwilling to supply us, we may not have sufficient materials or supplies to manufacture our products or process tissues. In addition, we rely on contract manufacturers to manufacture some of our products or to provide additional manufacturing capacity for some products. If these contract manufacturers fail to meet our quality standards or other requirements or if they are unable or unwilling to supply the products, we may not be able to meet demand for these products. Our ability to fully recover all possible losses from these suppliers and contract manufacturers may have practical limitations imposed by factors like industry standard contractual terms or the financial resources of the adverse party. As a further example of this risk, our supplier of TMR handpieces was informed in the fourth quarter of 2021 that the sole-source manufacturer of tubing used in the handpiece assembly had gone out of business, requiring us to work with our supplier to identify and qualify a new supplier before a disruption in handpiece availability occurs. In February 2023 we were notified that the sole-source manufacturer had gone out of business and, because a new supplier has yet to be identified and qualified, our handpiece supply would cease, effective immediately, and be disrupted in 2023 and potentially beyond.

Finally, the COVID-19 pandemic, the war in Ukraine, work force shortages, exchange rates, and inflation continue to impact the global supply chain; their impact on workforces, global mobility, material availability, demand, and shipping and reorder times and reliability has reportedly continued or worsened in many cases. The ongoing war in Ukraine may add to or exacerbate challenges faced by the global supply chain. See Part I, Item 1A, “Risk Factors – Business and Economic Risks - We are subject to a variety of risks due to our international operations and continued global expansion.” Although we have yet to experience any material effects of this impact on our supply chain or operations, we face an increasing risk that upstream disruptions may occur. Risks relating to the lingering effects of global supply chain disruptions may even continue after COVID-19’s risk as a global pandemic and the war in Ukraine have subsided.

Table of Contents

We are dependent on single and sole-source suppliers and single facilities.

Some of the materials, supplies, and services used in our product manufacturing and tissue processing, as well as some of our products, are sourced from single- or sole-source suppliers. As a result, our ability to negotiate favorable terms with those suppliers may be limited, and if those suppliers experience operational, financial, quality, or regulatory difficulties, or if those suppliers and/or their facilities refuse to supply us or cease operations temporarily or permanently, or if those suppliers take unreasonable business positions, we could be forced to cease product manufacturing or tissue processing until the suppliers resume operations, until alternative suppliers could be identified and qualified, or permanently if the suppliers do not resume operations and no alternative suppliers could be identified and qualified. We could also be forced to purchase alternative materials, supplies, or services with unfavorable terms due to diminished bargaining power.

As an example of these risks, in 2019 we lost our supply of handpieces for cardiac laser therapy resulting from a manufacturing location change at our supplier that ultimately required a PMA supplement and FDA approval before handpiece manufacturing and distribution could resume. Even though the FDA approved the PMA-S, our supplier was unable to fully resume production due to factors outside of our control. Due to these and other supplier issues, we had virtually no supply of handpieces during the first three quarters of 2021. Although handpiece supply resumed on a limited basis since the last quarter of 2021, we remain dependent on a sole-source manufacturer for these handpieces.

By way of additional non-limiting examples, our BioGlue product has three main product components: bovine protein, a cross linker, and a molded plastic resin delivery device. The bovine protein and cross linker are obtained from a small number of qualified suppliers. The delivery devices are manufactured by a single supplier, using resin supplied by a single supplier. We purchase grafts for our On-X AAP from a single supplier and various other components for our On-X valves come from single-source suppliers.

Our preservation services business and our ability to supply needed tissues is dependent upon donation of tissues from human donors by donor families. Donated human tissue is procured from deceased human donors by OPOs and tissue banks. We must rely on the OPOs and tissue banks that we work with to educate the public on the need for donation, to foster a willingness to donate tissue, to follow our donor screening and procurement procedures, and to send donated tissue to us. We have active relationships with approximately 60 OPOs and tissue banks throughout the US. As with any vendor, we believe these relationships with our OPOs are critical in the preservation services industry and that the breadth of these existing relationships provides us with a significant advantage over potential new entrants to this market. We also use various raw materials, including medicines and solutions, in our tissue processing. Some of these raw materials are manufactured by single suppliers or by a small group of suppliers.

Our aortic stent graft systems consist of two main product components: the stent graft and the delivery system. The stent graft is manufactured from several different raw materials that are manufactured internally or at various external suppliers, including single suppliers. The delivery systems we manufacture are comprised of several different raw materials and subassemblies. Our internal manufacturing processes include injection molding and machining of plastic parts, suturing of stent grafts, processing of Nitinol, and weaving of textiles. Our conventional polyester grafts consist of two main product components: polyester fabric and collagen coating. The polyester fabric is woven from a few different yarns that are supplied by an external supplier. The collagen suspension we manufacture is comprised of a collagenous tissue that is supplied by a single supplier. The conventional ePTFE grafts we manufacture are comprised of various raw materials supplied by several suppliers. For some products the ePTFE grafts are heparin coated. For these products, the heparin suspension we manufacture is comprised of a heparin solution that is also supplied by an external supplier. Our E-ventus BX bridging stent is supplied by an external supplier and our supply agreement expired at the end of 2022.

We have three internal manufacturing facilities: Austin, Texas for On-X products, Hechingen, Germany for internally manufactured aortic stent grafts, and Kennesaw, Georgia for all other products and services. Certain aortic stent graft assemblies are manufactured for us by a contract manufacturer in Slovakia. The AMDS product is solely manufactured by a supplier in Charlotte, North Carolina, the CardioGensis handpieces are solely manufactured by a supplier in Merrillville, Indiana, and the NEXUS product is solely manufactured by Endospan in Herzliya, Israel. If one of these suppliers or facilities ceases operations temporarily or permanently, for any reason including a pandemic or climate change related event, our business could be substantially disrupted.

Table of Contents

Although we work diligently to maintain adequate inventories of raw materials, components, supplies, subassemblies, and finished goods, there can be no assurance that we will be able to avoid all disruptions to our global supply chain, or disruptions to our sterilization or distribution networks. Any of these disruptions could have a material, adverse effect on our revenues, reputation, or profitability.

We are dependent on our specialized workforce.

Our business and future operating results depend in significant part upon the continued contributions of our specialized workforce, including key personnel, qualified personnel with medical device and tissue processing experience, and senior management with experience in the medical device or tissue processing space, some of whom would be difficult to replace. Our business and future operating results, including production at our manufacturing and tissue processing facilities, also depend in significant part on our ability to attract and retain qualified management, operations, processing, marketing, sales, and support personnel. Our primary facilities are in Kennesaw, Georgia; Austin, Texas; and Hechingen, Germany, where the supply of qualified medical device and tissue processing and other personnel is limited, competition for such personnel is significant, and we cannot ensure that we will be successful in attracting or retaining them. We face risks if we lose any key employees to other employers or due to severe illness, death, or retirement, if any of our key employees fail to perform adequately, or if we are unable to attract and retain skilled employees. This risk was exacerbated by the pandemic, and is expected to continue, as the competition for talent in the medical device industry and in the workforce generally has intensified substantially. As global economies have begun to emerge from the COVID-19 downturn, the expiration of COVID-19 related hiring freezes, the Great Resignation, increased opportunities for remote work, and increasing compensation pressure have resulted in a competition for talent and an unprecedented number of career changes. The resulting competition and worker shortages at all levels have impacted supply chains and distribution channels and our ability to attract and retain the specialized workforce necessary for our business and operations.

We continue to evaluate expansion through acquisitions of, or licenses with, investments in, and distribution arrangements with, other companies or technologies, which may carry significant risks.

One of our growth strategies is to pursue select acquisitions, licensing, or distribution rights with companies or technologies that complement our existing products, services, and infrastructure. In connection with one or more of these transactions, we may:

•Issue additional equity securities that would dilute our stockholders’ ownership interest;

•Use cash we may need in the future to operate our business;

•Incur debt, including on terms that could be unfavorable to us or debt we might be unable to repay;

•Structure the transaction resulting in unfavorable tax consequences, such as a stock purchase that does not permit a step-up in basis for the assets acquired;

•Be unable to realize the anticipated benefits of the transaction; or

•Assume material unknown liabilities associated with the acquired business.

We may not realize all the anticipated benefits of our business development activities.

As part of our efforts to drive growth by pursuing select acquisition, license, and distribution opportunities that are aligned to our objectives and complement our existing products, services, and infrastructure or to divest non-core product lines, we have completed several transactions in recent years and may pursue similar additional transactions in the future. Examples of these activities include the following:

•On December 1, 2017 we acquired JOTEC AG, a Swiss entity that we converted to JOTEC GmbH and subsequently merged with our Swiss acquisition entity, Jolly Buyer Acquisition GmbH and its subsidiaries;

•On September 11, 2019 we entered into various agreements with Endospan, an Israeli medical device manufacturer (the “Endospan Transaction”). The Endospan Transaction included an exclusive distribution agreement for NEXUS in Europe, the Endospan Loan, and a security purchase option agreement for Artivion to purchase all the outstanding Endospan securities from Endospan’s existing security holders upon FDA approval of NEXUS;

•On September 2, 2020 we acquired 100% of the outstanding shares of Ascyrus, the developer of AMDS; and

•On July 28, 2021 we entered into various agreements with Baxter and SMI related to the sale of our PerClot assets to Baxter and the termination of our existing material agreements with SMI.

Table of Contents

Our ability to realize the anticipated business opportunities, growth prospects, cost savings, synergies, and other benefits of these transactions depends on a number of factors including our ability to:

•Leverage our global infrastructure to sell and cross-market the acquired products;

•Drive adoption of NEXUS and AMDS in the European and other markets, including our ability to manage the substantial product training, implant support, and proctoring requirements for NEXUS procedures;

•Bring acquired products to the US market, including our acquired aortic stent grafts;

•Harness the aortic stent graft product pipeline and our research and development capabilities;

•Obtain regulatory approvals in relevant markets, including our ability to timely obtain FDA PMA for PerClot under the terms of the Baxter Transaction and to obtain or maintain CE Mark product certifications for pipeline and current products;

•Execute on development and clinical trial timelines for acquired products;

•Manage global inventories, including our ability to manage inventories for product lines with large numbers of product configurations and manage manufacturing and demand cycles to avoid excess inventory obsolescence due to shelf life expiration, particularly for processed tissues and aortic stent grafts;

•Carry, service, and manage significant debt and repayment obligations; and

•Manage the unforeseen risks and uncertainties related to these transactions, including any related to intellectual property rights.

Additionally, our ability to realize the anticipated business opportunities, growth prospects, synergies, and other benefits of the Endospan Transaction depends on a number of additional factors including Endospan’s ability to: (a) comply with the Endospan Loan and other debt obligations, and avoid an event of default; (b) successfully commercialize NEXUS, raise capital and drive adoption in markets in and outside of Europe; (c) meet demand for NEXUS; (d) meet quality and regulatory requirements for NEXUS; (e) manage any intellectual property risks and uncertainties associated with NEXUS; (f) obtain FDA approval of NEXUS; (g) remain a going concern; and (h) develop NEXUS product improvements to meet competitive threats and physician demand. As an example of this risk, the forecasted operating results related to NEXUS decreased in the fourth quarter of 2021, resulting in an impairment in the value of the Endospan Option, and a full write-down of the value of the Endospan Loan, reflecting decreased expectations with respect to the anticipated benefits of the Endospan Transaction.

Many of these factors are outside of our control and any one of them could result in increased costs, decreased revenues, and diversion of management’s time and energy. The benefits of these transactions may not be achieved within the anticipated time frame or at all. Any of these factors could negatively impact our earnings per share, decrease or delay the expected accretive effect of the transaction, and negatively impact the price of our common stock. In addition, if we fail to realize the anticipated benefits of a transaction, we could experience an interruption or loss of momentum in our existing business activities.

We may not realize all the anticipated benefits of our corporate rebranding and it may result in unanticipated disruptions to our on-going business.

In order to reflect our evolution to focus on providing innovative technologies to surgeons who treat patients with aortic disease, we changed our name to Artivion, Inc., effective January 18, 2022 (the “Corporate Rebrand”). The Corporate Rebrand also involved the adoption of a new ticker symbol on the New York Stock Exchange, “AORT.” We may face unanticipated disruptions to our business arising from the Corporate Rebrand, and it may expose us to additional risks, including:

•Disruptions to our day-to-day business operations including disruptions to our ability to receive or our customers’ ability to make timely payments;

•Disruptions to access certain markets or segments due to delays or other issues with regulatory approvals or updates arising from the Corporate Rebrand;

•Unanticipated delays or other impact on our pending regulatory applications or clinical trials arising from the Corporate Rebrand;

•Confusion within the marketplace, particularly with multiple points of contact in our downstream product flow involving purchasing and accounts payable departments and end users;

•Intellectual property risks associated with the adoption of a new corporate identity and trade dress; and

•Loss of brand equity associated with our legacy brands, including our CryoLife and JOTEC brands that will become less prominent over time.

Table of Contents

The Corporate Rebrand involved significant financial and resource investment and will continue to do so as we complete our global brand transitions over the coming years. The anticipated benefits of the Corporate Rebrand may not be achieved within the anticipated timeframe, without additional near or long-term investment, or at all. Any of these factors could negatively impact our revenues, earnings per share, decrease or delay the expected accretive effect of the Corporate Rebrand, and negatively impact the price of our common stock.

Significant disruptions of information technology systems or breaches of information security systems could adversely affect our business.

We rely upon a combination of sophisticated information technology systems as well as traditional recordkeeping to operate our business. In the ordinary course of business, we collect, store, and transmit confidential information (including, but not limited to, information about our business, financial information, personal data, intellectual property, and, in some instances, patient data). Our information technology and information security systems and records are potentially vulnerable to security breaches, service interruptions, data loss, or malicious attacks resulting from inadvertent or intentional actions by our employees, vendors, or other third parties. In addition, due to the COVID-19 pandemic, we have implemented remote work arrangements for some employees, and those employees may use outside technology and systems that are vulnerable to security breaches, service interruptions, data loss or malicious attacks, including by third parties.

While we have invested, and continue to invest, in our information technology and information security systems and employee information security training, there can be no assurance that our efforts will prevent all security breaches, service interruptions, or data losses. We have limited cyber-insurance coverage that may not cover all possible events, and this insurance is subject to deductibles and coverage limitations. Any security breaches, service interruptions, or data losses could adversely affect our business operations or result in the loss of critical or sensitive confidential information or intellectual property, or in financial, legal, business, and reputational harm to us or allow third parties to gain material, inside information that they may use to trade in our securities.

Industry Risks

Our products and tissues are highly regulated and subject to significant quality and regulatory risks.

The commercialization of medical devices and processing and distribution of human tissues are highly complex and subject to significant global quality and regulatory risks and as such, we face the following risks:

•Our products and tissues allegedly have caused, and may in the future cause, patient injury, which has exposed, and could in the future expose, us to liability claims that could lead to additional regulatory scrutiny;

•Our manufacturing and tissue processing operations are subject to regulatory scrutiny, inspections and enforcement actions, and regulatory agencies could require us to change or modify our operations or take other action, such as issuing product recalls or holds;

•Regulatory agencies could reclassify, re-evaluate, or suspend our clearances or approvals, or fail, or decline to, issue or reissue our clearances or approvals that are necessary to sell our products and distribute tissues;

•Regulatory and quality requirements are subject to change, which could adversely affect our ability to sell our products or distribute tissues; and

•Adverse publicity associated with our products, processed tissues, or our industry could lead to a decreased use of our products or tissues, increased regulatory scrutiny, or product or tissue processing liability claims.

As an example of these risks, on May 25, 2017 the European Union adopted a new MDR, which was fully implemented on May 26, 2021. The MDR places stricter requirements on manufacturers and European Notified Bodies regarding, among other things, product classifications and pre- and post-market clinical studies for product clearances and approvals which could result in product reclassifications or the imposition of other regulatory requirements that could delay, impede, or prevent our ability to commercialize existing, improved, or new products in the European Economic Area and other markets that require CE Marking. Additionally, to the extent the MDR places stricter requirements on manufacturers of custom-made devices, those new requirements could delay, impede, or otherwise impact the availability of our E-xtra Design Engineering products. COVID-19 has impacted the predictability and timelines associated with the MDR transition. Most recently, the European Commission announced an initiative to extend the MDR transition period and amend other related provisions but it is still unclear if this initiative will be adopted legislatively or whether it will be able to mitigate the challenges posed by the transition to the MDR.

Table of Contents

Since the implementation of the MDR, Notified Bodies must review any proposed changes to determine if they require evaluation under the MDR or if they can still be evaluated under currently held MDD certifications. Our inability to obtain certifications for changes under the transitional provisions of the MDR’s Article 120 or successfully submit proposed changes requiring MDR evaluation will delay implementation of those changes which could adversely impact our ability to obtain or renew certifications, clearances, or approvals for our products.

Additionally, as MDD-based CE Marks expire, recertification must be obtained under the MDR. Industry-wide, companies are experiencing delays in obtaining new and updated certifications under the MDR as Notified Bodies struggle to recover from COVID-19, deal with depleted workforces, and handle the volume of work required to transition tens of thousands of currently-marketed devices from the MDD to the MDR. As one such example, our MDD-based CE Mark for Chord-X expired in September 2022, which will impact our ability to supply certain territories once our saleable inventory is depleted. If Notified Bodies continue to struggle to meet demand and timely process submissions and recertifications, we may face additional disruptions associated with the MDR transition.

As another example of this risk, our CE-mark for BioGlue expired in December 2021. Due to delays renewing this CE-mark and transitioning BioGlue to a new Notified Body, our ability to supply certain markets with BioGlue was impacted. Although we were able to mitigate most of the impact by obtaining derogations in the majority of relevant territories, we may face similar risks and market disruptions relating to the MDR transition which continues to be in a state of change.

Finally, we anticipate additional regulatory impact as a result of Brexit. The UK Medicines and Healthcare Products Regulatory Agency has announced that CE Marking will continue to be recognized in the UK and certificates issued by EU-recognized Notified Bodies will continue to be valid in the UK market until June 30, 2023. Thereafter, all devices marketed in the UK will require UK Conformity Assessed Marks certified by a UK Approved Body (the re-designation of the UK Notified Body).

In 2019 our Notified Body in the UK, LRQA, informed us that it would no longer provide Notified Bodyservices for medical devices effective September 2019. The governing German competent authority, the Regierungspraesidium-Tubingen, granted us an extended grace period until December 31, 2021 to transfer LRQA-issued certifications for BioGlue and PhotoFix to a new Notified Body. Although our BioGlue CE Mark has been successfully transferred to our new Notified Body, DEKRA, we are still in the process of transferring PhotoFix to DEKRA. While progress has been made, failure to timely complete the transfer or any other delays in the MDR transition, may have a material, adverse effect on our ability to supply PhotoFix in affected jurisdictions, have a material, adverse impact on our business, and may also impact our MDSAP certifications. Failure to timely obtain new MDSAP certifications following their expiration may impact our ability to distribute covered products in Australia, Brazil, Canada, and Japan.

Reclassification by the FDA of CryoValve SG pulmonary heart valve (“CryoValve SGPV”) may make it commercially infeasible to continue processing the CryoValve SGPV.

In December 2019 we learned that the FDA is preparing to issue a proposed rule for reclassification of MMM allograft heart valves to Class III medical devices, which could include our CryoValve SGPV. Following a comment period and subsequent publication of any final rule, should the CryoValve SGPV be determined to be MMM, we expect to have approximately thirty months to submit an FDA PMA application, after which the FDA will determine if, and for how long, we may continue to provide these tissues to customers during review of the PMA application. To date, the FDA has not issued such a proposed final rule.

If the FDA ultimately classifies our CryoValve SGPV as a Class III medical device, and if there are delays in obtaining the PMA, if we are unsuccessful in obtaining the PMA, or if the costs associated with these activities are significant, we could decide that the requirements for continued processing of the CryoValve SGPV are too onerous, leading us to discontinue distribution of these tissues.

We may not be successful in obtaining clinical results or regulatory clearances/approvals for new and existing products and services, and our approved products and services may not achieve market acceptance.

Our growth and profitability depends in part upon our ability to develop, and successfully introduce, new products and services, or expand upon existing indications, clearances, and approvals, requiring that we invest significant time and resources to obtain new regulatory clearances/approvals, including investment into pre- and post-market clinical studies. Although we believe certain products and services in our portfolio or under development may be effective in a particular application, we cannot be certain until we successfully execute on relevant clinical trials, and the results we obtain from pre- and post-market clinical studies may be insufficient for us to obtain or maintain any required regulatory approvals or clearances.

We are currently seeking regulatory approval for BioGlue in China, where the Chinese regulatory body has made additional requests, and expressed several concerns, related to the application. We have obtained an extension of time until February 2024 in which to secure approval for BioGlue in China. If we cannot obtain approval by then or the costs to do so are prohibitive, we ultimately may be unable to sell BioGlue in China.

As another example of this risk, we obtained a CE Mark for E-nya in the fourth quarter of 2019 and began limited distribution of E-nya in the second quarter of 2020. In the fourth quarter of 2021 we suspended the limited release to evaluate modifications in response to customer feedback. We ultimately concluded the E-nya device would not achieve our market acceptance targets without additional design changes and ended the limited market release.

As a further example of this risk, in September 2022 we halted the PROACT Xa clinical trial based on the recommendation of the trial’s Data and Safety Monitoring Board (“DSMB”) due to insufficient evidence to support non-inferiority of apixaban to warfarin for valve thrombosis and thromboembolism. The DSMB found that continuing the trial was unlikely to achieve the primary endpoint while possibly exposing patients to increased risk.

Each of our trials, studies, and approvals is subject to the risks outlined herein.

We cannot give assurance that regulatory agencies will clear or approve these products and services or indications, or any new products and services or new indications, on a timely basis, if ever, or that the products and services or new indications will adequately meet the requirements of the market or achieve market acceptance. Pre- and post-market clinical studies may also be delayed or halted due to many factors beyond our control.

If we are unable to successfully complete the development of a product, service, or application, or if we determine for any reason not to complete development or obtain regulatory approval or clearance of any product, service, or application, particularly in instances when we have expended significant capital, this could materially, adversely affect our financial performance. Research and development efforts are time consuming and expensive, and we cannot be certain that these efforts will lead to commercially successful products or services. Halting R&D efforts and clinical trials prematurely may lead to accelerated or unanticipated wind down costs. Even the successful commercialization of a new product or service in the medical industry can be characterized by slow growth and high costs associated with marketing, under-utilized production capacity, and continuing research and development and education costs, among other things. The introduction of new products or services may require significant physician training or years of clinical evidence in order to gain acceptance in the medical community.

Regulatory enforcement activities or private litigation regarding the use of ethylene oxide (“EtO”), which is used to sterilize some of our products and components, could have a material, adverse impact on us.

Some of our products, including our On-X products, are sterilized using EtO. Although we have a small-scale EtO facility in Austin, Texas, we rely primarily on large-scale EtO facilities to sterilize our products. In addition, some of our suppliers use, or rely upon third parties to use, EtO to sterilize some of our product components. Concerns about the release of EtO into the environment at unsafe levels have led to increased activism and lobbying as well as various regulatory enforcement activities against EtO facilities, including closures and temporary closures, lawsuits against EtO service providers, and proposals increasing regulations related to EtO. The number of EtO facilities in the US is limited, and any permanent or temporary closures or disruption to their operations for any reason could delay, impede, or prevent our ability to commercialize our products. In addition, any regulatory enforcement activities against us for our use of EtO could result in financial, legal, business, and reputational harm to us.

Table of Contents

We may be subject to fines, penalties, and other sanctions if we are deemed to be promoting the use of our products for unapproved, or off-label, uses.

Our business and future growth depend on the continued use of our products for approved uses. Generally, regulators contend that, unless our products are approved or cleared by a regulatory body for alternative uses, we may not make claims about the safety or effectiveness of our products or promote them for such uses. Such limitations present a risk that law enforcement could allege that the nature and scope of our sales, marketing, or support activities, though designed to comply with all regulatory requirements, constitute unlawful promotion of our products for an unapproved use. We also face the risk that such authorities might pursue enforcement based on past activities that we discontinued or changed. Investigations concerning the promotion of unapproved uses and related issues are typically expensive, disruptive, and burdensome and generate negative publicity. If our promotional activities are found to be in violation of the law, we may face significant fines and penalties and may be required to substantially change our sales, promotion, grant, and educational activities. In addition, we or our officers could be excluded from participation in government healthcare programs such as Medicare and Medicaid.

Healthcare policy changes may have a material, adverse effect on us.

In response to perceived increases in healthcare costs in recent years, there have been, and continue to be, proposals by the governmental authorities, third-party payors, and elected office holders and candidates to impact public health, control healthcare costs and, more generally, to reform the healthcare systems. Additional uncertainty is anticipated as debates about healthcare, vaccines, and public health continue in light of the COVID-19 pandemic which may have an impact on US law relating to the healthcare industry. Many US healthcare laws, such as the Affordable Care Act, are complex, subject to change, and dependent on interpretation and enforcement decisions from government agencies with broad discretion. The application of these laws to us, our customers, or the specific services and relationships we have with our customers is not always clear. Our failure to anticipate accurately any changes to, or the repeal or invalidation of all or part of the Affordable Care Act and similar or future laws and regulations, or our failure to comply with them, could create liability for us, result in adverse publicity and negatively affect our business, results of operations, and financial condition.

Further, the growth of our business, results of operations and financial condition rely, in part, on customers in the healthcare industry that receive substantial revenues from governmental and other third-party payer programs. A reduction or less than expected increase in government funding for these programs or a change in reimbursement or allocation methodologies, or a change in reimbursement related to products designated as “breakthrough devices” by the FDA, could negatively affect our customers’ businesses and, in turn, negatively impact our business, results of operations and financial condition. Any changes that lower reimbursement for our products or reduce medical procedure volumes, could adversely affect our business and profitability.

Legal, Quality, and Regulatory Risks

As a medical device manufacturer and tissue services provider we are exposed to risk of product liability claims and our existing insurance coverage may be insufficient, or we may be unable to obtain insurance in the future, to cover any resulting liability.

Our products and processed tissues allegedly have caused, and may in the future cause, injury or result in other serious complications that may result in product or other liability claims from our customers or their patients. If our products are defectively designed, manufactured, or labeled, or contain inadequate warnings, defective components, or are misused, or are used contrary to our warnings, instructions, and approved indications, we may become subject to costly litigation that can have unpredictable and sometimes extreme outcomes.

We maintain claims-made insurance policies to mitigate our financial exposure to product and tissue processing liability and securities, claims, among others, that are reported to the insurance carrier while the policy is in effect. These policies do not include coverage for punitive damages. Although we have insurance for product and tissue processing liabilities, securities, property, and general liabilities, if we are unsuccessful in arranging cost-effective acceptable resolutions of claims, it is possible that our insurance program may not be adequate to cover any or all possible claims or losses, including losses arising out of natural disasters or catastrophic circumstances. Any significant claim could result in an increase in our insurance rates or jeopardize our ability to secure coverage on reasonable terms, if at all.

Table of Contents

Any securities or product liability/tissue processing claim, even a meritless or unsuccessful one, could be costly to defend, and result in diversion of our management’s attention from our business, adverse publicity, withdrawal of clinical trial participants, injury to our reputation, or loss of revenue.

We are subject to various US and international bribery, anti-kickback, false claims, privacy, transparency, and similar laws, any breach of which could cause a material, adverse effect on our business, financial condition, and profitability.

Our relationships with physicians, hospitals, and other healthcare providers are subject to scrutiny under various US and international bribery, anti-kickback, false claims, privacy, transparency, and similar laws, often referred to collectively as “healthcare compliance laws.” Healthcare compliance laws are broad, sometimes ambiguous, complex, and subject to change and changing interpretations. The ongoing war in Ukraine and the current and future sanctions imposed on Russia and others as a result may exacerbate these risks. See also Part I, Item 1A, “Risk Factors – Business and Economic Risks - We are subject to a variety of risks due to our international operations and continued global expansion.” Possible sanctions for violation of these healthcare compliance laws include fines, civil and criminal penalties, exclusion from government healthcare programs, and despite our compliance efforts, we face the risk of an enforcement activity or a finding of a violation of these laws.

We have entered into consulting and product development agreements with healthcare professionals and healthcare organizations, including some who may order our products or make decisions to use them. We have also adopted the AdvaMed Code of Conduct, the MedTech Europe Code of Ethical Business Practice, and the APACMed Code of Ethical Conduct which govern our relationships with healthcare professionals to bolster our compliance with healthcare compliance laws. While our relationships with healthcare professionals and organizations are structured to comply with such laws and we conduct training sessions on these laws and codes, it is possible that enforcement authorities may view our relationships as prohibited arrangements that must be restructured or for which we would be subject to other significant civil or criminal penalties or debarment. In any event, any enforcement review of or action against us as a result of such review, regardless of outcome, could be costly and time consuming. Additionally, we cannot predict the impact of any changes in or interpretations of these laws, whether these changes will be retroactive or will have effect on a going-forward basis only.

The proliferation of new and expanded data privacy laws, including the General Data Protection Regulation in the European Union, could adversely affect our business.

An increasing number of federal, state, and foreign data privacy laws and regulations, which can be enforced by private parties or governmental entities, have been or are being promulgated and are constantly evolving. These laws and regulations may include new requirements for companies that receive or process an individual’s personal data (including employees), which increases our operating costs and requires significant management time and energy. Many of these laws and regulations, including the European Union’s General Data Protection Regulation (“GDPR”) also include significant penalties for noncompliance. Although our personal data practices, policies, and procedures are intended to comply with GDPR and other data privacy laws and regulations, there can be no assurance that regulatory or enforcement authorities will view our arrangements as being in compliance with applicable laws, or that one or more of our employees or agents will not disregard the rules we have established. Any privacy related government enforcement activities may be costly, result in negative publicity, or subject us to significant penalties.

Some of our products and technologies are subject to significant intellectual property risks and uncertainty.

We own trade secrets, patents, patent applications, and licenses relating to our technologies and trademarks and goodwill related to our products and services, which we believe provide us with important competitive advantages. We cannot be certain that we will be able to maintain our trade secrets, that our pending patent applications will issue as patents, or that no one will challenge the validity or enforceability of any intellectual property that we adopt, own, or license. Competitors may independently develop our proprietary technologies or design non-infringing alternatives to patented inventions. We do not control the maintenance, prosecution, enforcement, or strategy for in-licensed intellectual property and as such are dependent in part on the owners of these rights to maintain their viability. Their failure to do so could significantly impair our ability to exploit those technologies. Additionally, our technologies, products, or services could infringe intellectual property rights owned by others, or others could infringe our intellectual property rights.

Table of Contents

If we become involved in intellectual property disputes, the costs could be expensive, and if we were to lose or decide to settle, the amounts or effects of the settlement or award by a tribunal could be costly.

Risks Relating to Our Indebtedness

The agreements governing our indebtedness contain restrictions that limit our flexibility in operating our business.

The agreements governing our indebtedness contain, and any instruments governing future indebtedness of ours may contain, covenants that impose significant operating and financial restrictions on us and certain of our subsidiaries, including (subject in each case to certain exceptions) restrictions or prohibitions on our and certain of our subsidiaries’ ability to, among other things:

•Incur or guarantee additional debt or create liens on certain assets;

•Pay dividends on or make distributions of our share capital, including repurchasing or redeeming capital stock, or make other restricted payments, including restricted junior payments;

•Enter into agreements that restrict our subsidiaries’ ability to pay dividends to us, repay debt owed to us or our subsidiaries, or make loans or advances to us or our other subsidiaries;

•Enter into certain transactions with our affiliates including any transaction or merger or consolidation, liquidation, winding-up, or dissolution; convey, sell, lease, exchange, transfer or otherwise dispose of all or any part of our business, assets or property; or sell, assign, or otherwise dispose of any capital stock of any subsidiary;

•Enter into certain rate swap transactions, basis swaps, credit derivative transactions, and other similar transactions, whether relating to interest rates, commodities, investments, securities, currencies, or any other relevant measure, or transactions of any kind subject to any form of master purchase agreement governed by the International Swaps and Derivatives Association, Inc., any International Foreign Exchange Master Agreement, or any other master agreement;

•Amend, supplement, waive, or otherwise modify our or our subsidiaries' organizational documents in a manner that would be materially adverse to the interests of the lenders, or change or amend the terms of documentation regarding junior financing in a manner that would be materially adverse to the interests of the lenders;

•Make changes to our and our subsidiaries’ fiscal year without notice to the administrative agent;

•Enter into agreements which restrict our ability to incur liens;

•Engage in any line of business substantially different from that in which we are currently engaged; and

•Make certain investments, including strategic acquisitions or joint ventures.

Our indebtedness could adversely affect our ability to raise additional capital to fund operations and limit our ability to react to changes in the economy or our industry.

Our current and future levels of indebtedness could adversely affect our ability to raise additional capital, limit our operational flexibility, and hinder our ability to react to changes in the economy or our industry. It may also limit our ability to borrow money, require us to dedicate substantial portions of our cash flow to repayment, and restrict our ability to invest in business opportunities. Because most of our borrowings are at a variable rate of interest, we are exposed to interest rate fluctuations.

We have pledged substantially all of our US assets as collateral under our existing Credit Agreement. If we default on the terms of such credit agreements and the holders of our indebtedness accelerate the repayment of such indebtedness, there can be no assurance that we will have sufficient assets to repay our indebtedness.

A failure to comply with the covenants in our existing Credit Agreement could result in an event of default, which, if not cured or waived, could have a material, adverse effect on our business, financial condition, and profitability. In the event of any such default, the holders of our indebtedness:

•Will not be required to lend any additional amounts to us; and

•Could elect to declare all indebtedness outstanding, together with accrued and unpaid interest and fees, to be due and payable and terminate all commitments to extend further credit, if applicable.

If we are unable to repay those amounts, the holders of our secured indebtedness could proceed against their secured collateral to seek repayment out of proceeds from the sale or liquidation of our assets. If our indebtedness were to be accelerated, there can be no assurance that our assets would be sufficient to repay such indebtedness in full.

Risks Related to Ownership of our Common Stock

Our business could be negatively impacted as a result of shareholder activism.

In recent years, shareholder activists have become involved in the governance, strategic direction, and operations of companies. Such involvement with us may disrupt our business and divert the attention of our management, and any perceived uncertainties as to our future direction resulting from such involvement could result in the loss of business opportunities, be exploited by our competitors, cause concern for our current or potential customers, cause significant fluctuations in stock price, or make it more difficult to attract and retain qualified personnel and business partners.

Our business could be impacted by increased shareholder emphasis on environmental, social, and governance matters.

Investors and other key stakeholders are increasingly focusing on areas of corporate responsibility, and particularly matters related to environmental, social, and governance (“ESG”) factors. Institutional investors have expressed expectations with respect to ESG matters that they use to guide their investment strategies and may, in some cases, choose not to invest in us if they believe our ESG policies are lagging or inadequate. Other stakeholders also have expectations regarding ESG factors, such as employees or potential employees who desire to work for a company that reflects their personal values. These areas of focus are continuing to evolve, as are the criteria that investors assess companies’ performance in these areas. Investors are increasingly looking to companies that demonstrate strong ESG and sustainability practices as an indicator of long-term resilience, especially in light of events such as the COVID-19 pandemic. Keeping up with and meeting these expectations may disrupt our business and divert the attention of our management, and we may be unable to make the investments in ESG programs that our competitors with greater financial resources are able to make. Failure to meet the expectations of investors and other stakeholders in these areas may damage our reputation, impact employee retention, impact the willingness of our customers to do business with us, or otherwise impact our financial results and stock price.

We do not anticipate paying any dividends on our common stock for the foreseeable future.

In December 2015 our Board of Directors discontinued dividend payments on our common stock for the foreseeable future. If we do not pay cash dividends, our shareholders may receive a return on their investment in our common stock only through appreciation of shares of our common stock that they own. In addition, restrictions in our credit facility limit our ability to pay future dividends.

Provisions of Delaware law and anti-takeover provisions in our organizational documents may discourage or prevent a change of control, even if an acquisition would be beneficial to shareholders, which could affect our share price adversely and prevent attempts by shareholders to remove current management.

Effective January 1, 2022 we reincorporated in Delaware. Our status as a Delaware corporation and the anti-takeover provisions of the Delaware General Corporation Law may discourage, delay, or prevent a change in control by prohibiting us from engaging in a business combination with an interested stockholder for a period of three years after the person becomes an interested stockholder, even if a change of control would be beneficial to our existing stockholders. In addition, the organizational documents adopted in connection with our reincorporation contain provisions that restrict persons who may call shareholder meetings, allow the issuance of blank-check preferred stock without the vote of shareholders, and allow the Board of Directors to fill vacancies and fix the number of directors. These provisions of Delaware law and our articles of incorporation and bylaws could prevent attempts by shareholders to remove current management, prohibit or delay mergers or other changes of control transactions, and discourage attempts by other companies to acquire us, even if such a transaction would be beneficial to our shareholders. The effects of reincorporation in Delaware are detailed in our 2021 Special Proxy Statement and Notice of Special Meeting filed with the SEC on October 7, 2021.

Item 2. Properties.

Our corporate headquarters consist of approximately 190,400 square feet of leased manufacturing, administrative, laboratory, and warehouse space located on a 21.5-acre setting, with an additional 14,400 square feet of off-site warehouse space both located in Kennesaw, Georgia. The manufacturing and tissue processing space includes approximately 20,000 square feet of class 10,000 clean rooms and 8,000 square feet of class 100,000 clean rooms. This extensive clean room environment provides a controlled aseptic environment for manufacturing and tissue preservation. Two back-up emergency generators assure continuity of our manufacturing operations and liquid nitrogen freezers maintain preserved tissue at or below –135°C. We manufacture products from our Medical Devices segment, including BioGlue and PhotoFix, and process and preserve tissues from our Preservation Services segment at our headquarters facility. Our corporate headquarters also includes a CardioGenesis cardiac laser therapy maintenance and evaluation laboratory space.

Our corporate complex includes the Ronald C. Elkins Learning Center, a 3,600 square foot auditorium that holds 225 participants, and a 1,500 square foot training lab, both equipped with closed-circuit and satellite television broadcast capability allowing live worldwide broadcasts. The Ronald C. Elkins Learning Center provides visiting surgeons with a hands-on training environment for surgical and implantation techniques for our technology platforms.

Our primary European subsidiary, JOTEC, located in Hechingen, Germany, maintains facilities that consist of approximately 156,000 square feet of leased manufacturing, administrative, laboratory, and warehouse space where we manufacture aortic stent grafts.

Our On-X facility consists of approximately 75,000 square feet of combined manufacturing, administrative, laboratory, warehouse, and office space leased in Austin, Texas.

We lease small amounts of ancillary office and warehouse space in various countries in which we operate direct sales subsidiaries, including in Brazil, Greece, Italy, Poland, Spain, Switzerland, and the United Kingdom. In April 2022 we opened a distribution center in Singapore to support sales activities in the APAC region.

Item 3. Legal Proceedings.

From time to time, we are involved in legal proceedings concerning matters arising in connection with the conduct of our business activities. We regularly evaluate the status of legal proceedings in which we are involved in order to assess whether a loss is probable or there is a reasonable possibility that a loss or additional loss may been incurred, and to determine if accruals are appropriate. We further evaluate each legal proceeding to assess whether an estimate of possible loss or range of loss can be made.

Based on current knowledge, management does not believe that there are any pending matters that potentially could have a material, adverse effect on our business, financial condition, results of operations, or cash flows. However, we are engaged in various legal actions in the normal course of business. There can be no assurances in light of the inherent uncertainties involved in any potential legal proceedings, some of which are beyond our control, and an adverse outcome in any legal proceeding could be material to our results of operations or cash flows for any particular reporting period.

Overview

Artivion, Inc. (“Artivion,” the “Company,” “we,” or “us”), is a leader in the manufacturing, processing, and distribution of medical devices and implantable human tissues used in cardiac and vascular surgical procedures for patients with aortic disease. We have four major product families: aortic stent grafts, surgical sealants, On-X® mechanical heart valves and related surgical products, and implantable cardiac and vascular human tissues. Aortic stent grafts include aortic arch stent grafts, abdominal stent grafts, and synthetic vascular grafts. Aortic arch stent grafts include our E-vita Open NEO, E-vita Open Plus, AMDS, NEXUS, and E-vita Thoracic 3G products. Abdominal stent grafts include our E-xtra Design Engineering, E-nside, E-tegra, E-ventus BX, and E-liac products. Surgical sealants include BioGlue® Surgical Adhesive (“BioGlue”) products. In addition to these four major product families, we sell or distribute PhotoFix® bovine surgical patches, CardioGenesis® cardiac laser therapy, and PerClot® hemostatic powder (prior to the sale to a subsidiary of Baxter International, Inc. (“Baxter”)).

For the year ended December 31, 2022 we reported annual revenues of $313.8 million, increasing 5% over the prior year. Excluding the effects of foreign exchange, revenues increased 9% over the prior year. The increase in revenues was due to increases in revenues from aortic stent grafts, On-X products, preservation services, and other products, partially offset by a decrease in revenues from surgical sealants. For the year ended December 31, 2022 we reported a net loss of $19.2 million. See the “Results of Operations” section below for additional analysis of the fourth quarter and full year 2022 results. See Part I, Item 1, “Business,” for further discussion of our business and activities during 2022.

Effects of COVID-19

The COVID-19 pandemic continued to impact global economic conditions during 2022 including having an impact on our operations. Our efforts to protect our supply chain and reduce the spread of COVID-19 among our employees, including our work-from-home arrangements, have been successful to date as we have continued to operate all manufacturing sites at full production. These efforts have not materially affected our ability to maintain our business operations, including the operation of financial reporting systems, internal control over financial reporting, or disclosure controls and procedures. Although we have scaled back most of our COVID-19 mitigation efforts, we continue to monitor the impact of the pandemic and the emergence of new variants on our business and recognize that COVID-19 and its effects could continue to negatively impact our business and results of operations during 2023 and beyond.

Table of Contents

The COVID-19 pandemic has also impacted certain aspects of the global supply chain and resulted in supply chain inflation. Although we have yet to experience any material effects on our supply chain or operations, we face an increasing risk that upstream disruptions may occur or worsen. As global economies continue to recover from the COVID-19 downturn, increased opportunities for remote work, and increasing compensation pressure have resulted in competition for talent and an unprecedented number of retirements or career changes. The resulting worker shortages at all levels have impacted supply chains, distribution channels, and employers’ and our own ability to adequately staff operations. These shortages to date, have impacted, and may impact our operations going forward. Hospitals and other healthcare providers have also experienced staffing shortages impacting our business including increased restrictions on elective and non-emergent procedures, restrictions on access to healthcare facilities, cancellation of elective procedures, and the re-allocation of scarce resources.

The extent to which our operations and financial performance will be impacted by the pandemic in 2023 and beyond will depend largely on future developments, including changes in hospital utilization rates and staffing, prevalence and severity of new variants, disruptions to workforce availability, and the impact on the global supply chain. Due to the significant uncertainty related to the pandemic and its impact on macroeconomic conditions, our operations, revenues, financial conditions, profitability, and cash flows may be materially impacted.

See the “Risk Factors” identified in Part I, Item 1A of this form 10-K for risks related to COVID-19.

Critical Accounting Policies

A summary of our significant accounting policies is included in Part II, Item 8, Note 1 of the “Notes to Consolidated Financial Statements.” We believe that the consistent application of these policies enables us to provide users of the financial statements with useful and reliable information about our operating results and financial condition. The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the US, which require us to make estimates and assumptions. The following are accounting policies that we believe are most important to the portrayal of our financial condition and results of operations and may involve a higher degree of judgment and complexity.

Deferred Preservation Costs, net

Deferred preservation costs include costs of cardiac and vascular tissues available for shipment, tissues currently in active processing, and tissues held in quarantine pending release to implantable status. By federal law, human tissues cannot be bought or sold; therefore, the tissues we preserve are not held as inventory. The costs we incur to procure and process cardiac and vascular tissues are instead accumulated and deferred. Deferred preservation costs are stated at the lower of cost or net realizable value on a first-in, first-out basis and are deferred until revenue is recognized. Upon shipment of tissue to an implanting facility, revenue is recognized, and the related deferred preservation costs are expensed as cost of preservation services. Cost of preservation services also includes, as applicable, lower of cost or net realizable value write-downs and impairments for tissues not deemed to be recoverable, and includes, as incurred, idle facility expense, excessive spoilage, extra freight, and re-handling costs.

The calculation of deferred preservation costs involves judgment and complexity and uses the same principles as inventory costing. Donated human tissue is procured from deceased human donors by organ and tissue procurement organizations (“OPOs”) and tissue banks that provide the tissue to us for processing, preservation, and distribution. Deferred preservation costs consist primarily of the procurement fees charged by the OPOs and tissue banks, direct labor and materials (including salary and fringe benefits, laboratory supplies and expenses, and freight-in charges), and indirect costs (including allocations of costs from support departments and facility allocations). Fixed production overhead costs are allocated based on actual tissue processing levels, to the extent that they are within the range of the facility’s normal capacity.

These costs are then allocated among the tissues processed during the period based on cost drivers, such as the number of donors or number of tissues processed. We apply a yield estimate to all tissues in process and in quarantine to estimate the portion of tissues that will ultimately become implantable. We estimate quarantine and in process yields based on our experience and reevaluate these estimates periodically. Actual yields could differ significantly from our estimates, which could result in a change in tissues available for shipment and could increase or decrease the balance of deferred preservation costs. These changes could result in additional cost of preservation services expense or could increase per tissue preservation costs, which would impact gross margins on tissue preservation services in future periods.

Table of Contents

We regularly evaluate our deferred preservation costs to determine if the costs are appropriately recorded at the lower of cost or net realizable value. We also evaluate our deferred preservation costs for costs not deemed to be recoverable, including tissues not expected to ship prior to the expiration date of their packaging. Lower of cost or net realizable value write-downs are recorded if the tissue processing costs incurred exceed the estimated market value of the tissue services, based on recent average service fees at the time of the evaluation. Impairment write-downs are recorded based on the book value of tissues deemed to be impaired. Actual results may differ from these estimates. Write-downs of deferred preservation costs are expensed as cost of preservation services, and these write-downs are permanent impairments that create a new cost basis, which cannot be restored to its previous levels if our estimates change.

Fair Value Measurements

We record certain financial instruments, including cash equivalents, at fair value on a recurring basis. We may make an irrevocable election to measure other financial instruments at fair value on an instrument-by-instrument basis. Fair value financial instruments are recorded in accordance with the fair value measurement framework.

We also measure certain assets and liabilities at fair value on a non-recurring basis. These non-recurring valuations include evaluating assets such as certain financial assets, long-lived assets, and indefinite lived intangible assets for impairment, allocating value to assets in an acquired asset group and applying accounting for business combinations and the initial recognition of liabilities such as contingent consideration. We use the fair value measurement framework to value these assets and liabilities and report these fair values in the periods in which they are recorded or written down.

The fair value measurement framework includes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair values in their broad levels. These levels from highest to lowest priority are as follows:

•Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities;

•Level 2: Quoted prices in active markets for similar assets or liabilities or observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and

•Level 3: Unobservable inputs or valuation techniques that are used when little or no market data is available.

The determination of fair value and the assessment of a measurement’s placement within the hierarchy requires judgment. Level 3 valuations often involve a higher degree of judgment and complexity. Level 3 valuations may require the use of various cost, market, or income valuation methodologies applied to our unobservable estimates and assumptions. Our assumptions could vary depending on the asset or liability valued and the valuation method used. Such assumptions could include: estimates of prices, earnings, costs, actions of market participants, market factors, or the weighting of various valuation methods. We may also engage external advisors to assist in determining fair value, as appropriate.

Although we believe that the recorded fair value of our financial instruments is appropriate, these fair values may not be indicative of net realizable value or reflective of future fair values.

Deferred Income Taxes

Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and tax return purposes. We assess the recoverability of our deferred tax assets and provide a valuation allowance against our deferred tax assets when, as a result of this analysis, we believe it is more likely than not that some portion or all of our deferred tax assets will not be realized.

Assessing the recoverability of deferred tax assets involves judgment and complexity, including the consideration of prudent and feasible tax planning. Estimates and judgments used in the determination of the need for a valuation allowance and in calculating the amount of a needed valuation allowance include, but are not limited to, the following:

•The ability to carry back deferred tax attributes to a prior tax year;

•Timing of the anticipated reversal of book/tax temporary differences;

•Projected future operating results;

•Anticipated future state tax apportionment;

•Timing and amounts of anticipated future taxable income;

•Evaluation of statutory limits regarding usage of certain tax assets; and

•Evaluation of the statutory periods over which certain tax assets can be utilized.

Table of Contents

Significant changes in the factors above, or other factors, could affect our ability to use our deferred tax assets. Such changes could have a material, adverse impact on our profitability, financial position, and cash flows. We will continue to assess the recoverability of our deferred tax assets, as necessary, when we experience changes that could materially affect our prior determination of the recoverability of our deferred tax assets.

Valuation of Acquired Assets or Businesses

As part of our corporate strategy, we are seeking to identify and capitalize upon acquisition opportunities of complementary product lines and companies. We evaluate and account for acquired patents, licenses, distribution rights, and other tangible or intangible assets as the purchase of an asset or asset group, or as a business combination, as appropriate. The determination of whether the purchase of a group of assets should be accounted for as an asset group or as a business combination requires judgment based on the weight of available evidence.

For the purchase of an asset group, we allocate the cost of the asset group, including transaction costs, to the individual assets purchased based on their relative estimated fair values. In-process research and development acquired as part of an asset group is expensed upon acquisition.

We account for business combinations using the acquisition method. Under this method, the allocation of the purchase price is based on the fair value of the tangible and identifiable intangible assets acquired and the liabilities assumed as of the date of the acquisition. The excess of the purchase price over the estimated fair value of the tangible net assets and identifiable intangible assets is recorded as goodwill. The identifiable intangible assets typically consist of developed technology, customer relationships, and in-process research and development costs. Transaction costs related to a business combination are expensed as incurred. In-process research and development acquired as part of a business combination is accounted for as an indefinite-lived intangible asset until the related research and development project gains regulatory approval or is discontinued.

We typically engage external advisors to assist us in determining the fair value of acquired asset groups or business combinations, using valuation methodologies such as: the excess earnings, the discounted cash flow, Monte Carlo, or the relief from royalty methods. The determination of fair value in accordance with the fair value measurement framework requires significant judgments and estimates, including, but not limited to: timing of product life cycles, estimates of future revenues, estimates of profitability for new or acquired products, cost estimates for new or changed manufacturing processes, estimates of the cost or timing of obtaining regulatory approvals, estimates of the success of competitive products, and discount rates and represent Level 3 measurements. We, in consultation with our advisors, make these estimates based on our prior experiences and industry knowledge. We believe that our estimates are reasonable, but actual results could differ significantly from our estimates. A significant change in our estimates used to value acquired asset groups or business combinations could result in future write-downs of tangible or intangible assets acquired by us and, therefore, could materially impact our financial position and profitability. If the value of the liabilities assumed by us, including contingent liabilities, is determined to be significantly different from the amounts previously recorded in purchase accounting, we may need to record additional expenses or write-downs in future periods, which could materially impact our financial position and profitability.

Results of Operations

Year Ended December 31, 2022 Compared to Year Ended December 31, 2021

(Tables in thousands)

Revenues

Products:

Revenues increased 5% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. The increase in revenues for the twelve months ended December 31, 2022 was due to an increase in revenues from aortic stent grafts, On-X products, preservation services, and other products, partially offset by a decrease in revenues from surgical sealants. Excluding the effects of foreign exchange, revenues increased 9% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. Revenues for the twelve months ended December 31, 2022 and 2021 were negatively impacted in certain regions by delays or cancellations of some surgical procedures as a result of reduced hospital capacity and staffing and hospital restrictions due to the COVID-19 pandemic. The revenue impact from COVID-19 was smaller and varied regionally during the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021.

A detailed discussion of the changes in product revenues and preservation services revenues for the twelve months ended December 31, 2022 is presented below.

Products

Revenues from products increased 4% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. The increase was due to an increase in revenues from aortic stent grafts, On-X products, and other products, partially offset by a decrease in revenues from surgical sealants. A discussion of the changes in product revenues for aortic stent grafts, surgical sealants, On-X, and other product revenues is presented below.

Sales of certain products through our direct sales force and distributors across Europe and various other countries are denominated in a variety of currencies including Euros, British Pounds, Polish Zlotys, Swiss Francs, Brazilian Reals, and Canadian Dollars, with a concentration denominated in Euros. Each currency is subject to exchange rate fluctuations. For the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021, the US Dollar strengthened in comparison to major currencies, resulting in revenue decreases when these foreign currency denominated transactions were translated into US Dollars. Future changes in these exchange rates could have a material, adverse effect on our revenues denominated in these currencies. Additionally, our sales to many distributors around the world are denominated in US Dollars, and although these sales are not directly impacted by currency exchange rates, we believe that some of our distributors may delay or reduce purchases of products in US Dollars depending on the relative price of these goods in their local currencies.

Aortic Stent Grafts

Aortic stent grafts include aortic arch stent grafts, abdominal stent grafts, synthetic vascular grafts, and original equipment manufacturing (“OEM”) aortic stent graft products. Aortic arch stent grafts include our E-vita Open NEO, E-vita Open Plus, AMDS, NEXUS, and E-vita Thoracic 3G products. Abdominal stent grafts include our E-xtra Design Engineering, E-nside, E-tegra, E-ventus BX, and E-liac products. Aortic stent grafts are used in endovascular and open vascular surgery for the treatment of complex aortic arch, thoracic, and abdominal aortic diseases. Our aortic stent grafts are primarily distributed in international markets.

Aortic stent grafts revenues increased 9% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021.

Aortic stent grafts revenues, excluding OEM, increased 10% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. This increase in revenue was primarily due to an increase in volume of units sold, which increased revenues by 20%, and an increase in average sales prices, which increased revenues by 1%, partially offset by the effect of foreign exchange rates, which decreased revenues by 11%.

On a constant currency basis, revenues for aortic stent grafts, excluding OEM, increased 22% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. The increase in revenues was partially due to improved conditions from the COVID-19 pandemic for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. Revenues for the twelve months ended December 31, 2022 increased primarily in Europe, the Middle East, and Africa (collectively, “EMEA”), Canada, Asia Pacific (“APAC”), and Latin America (“LATAM”). The revenue increase in EMEA for the twelve months ended December 31, 2022 was due to increases in sales direct (to hospitals) and indirect (through distributor) markets. The revenue increase in APAC for the twelve months ended December 31, 2022 was primarily due to an increase in sales of newly launched aortic stent grafts and distributor buying patterns in certain markets. The revenue increase in LATAM for the twelve months ended December 31, 2022 was primarily due to market penetration in certain regions. OEM sales of aortic stent grafts accounted for less than 1% of product revenues for the twelve months ended December 31, 2022 and 2021.

Surgical Sealants

Surgical sealants include BioGlue products used as an adjunct to standard methods of achieving hemostasis (such as sutures and staples) in adult patients in open surgical repair of large vessels (such as aorta, femoral, and carotid arteries).

Revenues from the sales of surgical sealants decreased 8% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. This decrease in revenues was primarily due to a decrease in the volume and a change in the mix of milliliters sold, which decreased revenues by 5%, and the effect of foreign exchange rates, which decreased revenues by 3%.

On a constant currency basis, revenues from the sales of surgical sealants decreased 5% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. The decrease in revenues was primarily due to decreases in revenues in North America and EMEA, partially offset by increases in revenues in APAC and LATAM.

During the twelve months ended December 31, 2021 revenues from the sales of surgical sealants in North America were larger than in the twelve months ended December 31, 2022, primarily due to inventory restocking orders placed during the first half of 2021 as hospitals experienced reduced impact from the COVID-19 pandemic and began resuming more normal operations. Revenues were negatively impacted during the first quarter of 2022 due to delays and cancellations of some surgical procedures due to hospital staffing challenges as a result of a new COVID-19 variant.

During the twelve months ended December 31, 2022 revenues from sales of surgical sealants in EMEA were adversely impacted primarily due to temporary commercialization restrictions resulting from the expiration of our BioGlue CE Mark during our transition to a new Notified Body. We received renewal of our BioGlue CE Mark and completed our Notified Body transition late in the fourth quarter of 2022.

Domestic revenues from surgical sealants accounted for 49% of total surgical sealant revenues for the twelve months ended December 31, 2022 and 51% of total surgical sealant revenues for the twelve months ended December 31, 2021.

On-X

The On-X catalogue of products includes the On-X prosthetic aortic and mitral heart valves and the On-X ascending aortic prosthesis (“AAP”) for heart valve replacement. On-X product revenues also include revenues from the distribution of CarbonAid® CO2 diffusion catheters and from the sale of Chord-X® ePTFE sutures for mitral chordal replacement. On-X also generates revenue from pyrolytic carbon coating services for OEM customers.

On-X product revenues increased 11% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021.

On-X product revenues, excluding OEM, increased 11% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. This increase in revenues was primarily due to an increase in volume of units sold, which increased revenues by 10%, and an increase in average sales prices, which increased revenues by 3%, partially offset by the effect of foreign exchange rates, which decreased revenues by 2%.

On a constant currency basis, On-X revenues, excluding OEM, increased 13% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. The increase in revenues was primarily due to revenue increases in North America, EMEA, and LATAM. The revenue increases in these markets were partially due to improved conditions from the COVID-19 pandemic for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. The increase in revenues was also impacted by customer buying patterns in North America, an increase of shipments primarily in direct markets in EMEA, and market penetration in certain regions in LATAM. On-X OEM sales accounted for less than 1% of product revenues for the twelve months ended December 31, 2022 and 2021.

Domestic revenues from On-X accounted for 63% of total On-X revenues for the twelve months ended December 31, 2022, and 62% of On-X revenues for the twelve months ended December 31, 2021.

Other

Other revenues are comprised of PhotoFix, PerClot (prior to the Baxter Transaction, described below), and CardioGenesis cardiac laser therapy product revenues.

On July 28, 2021 we entered into an asset purchase agreement and other ancillary agreements related to the sale of PerClot, a polysaccharide hemostatic agent used in surgery, to Baxter, and an agreement to terminate all of our material agreements with Starch Medical, Inc. (“SMI”) related to PerClot (collectively the “Baxter Transaction”).

Other revenues increased 2% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021.

The increase in other revenues for the twelve months ended December 31, 2022 was primarily due to an increase in CardioGenesis cardiac laser therapy product services, partially offset by a decrease in PerClot product revenues. The increase in CardioGenesis cardiac therapy product revenues for the twelve months ended December 31, 2022 was primarily due to our ability to resume limited sales of handpieces during the fourth quarter of 2021, as further described below. The decrease in PerClot product revenues for the twelve months ended December 31, 2022 was due to the Baxter Transaction, described in more detail in Part II, Item 8, Note 2 of "Notes to Consolidated Financial Statements" of this form 10-K.

Revenues from our CardioGenesis cardiac laser therapy product line historically consisted primarily of sales of handpieces and, in certain periods, the sale of laser consoles. During the nine months ended September 30, 2021 we had minimal revenues from the CardioGenesis cardiac laser therapy product line as we did not have a supply of handpieces due to the FDA’s review of our supplier’s change in manufacturing location. After obtaining authorization to resume commercial distribution, our supplier resumed manufacturing a limited supply of handpieces allowing us to resume limited sales during the fourth quarter of 2021. In February 2023 our supplier of handpieces informed us that the sole-source manufacturer of tubing used in the handpiece assembly had gone out of business and, because a new supplier has yet to be identified and qualified, they are exiting the business and will no longer be supplying handpieces effective immediately. We are evaluating the impact of this disruption on our business and possible avenues for resumption of supply including the evaluation of alternate suppliers and handpiece manufacturers. We don’t expect revenues from the CardioGenesis cardiac laser therapy product line after the first quarter of 2023 until we qualify and obtain approval for a new hand piece manufacturing source.

Preservation Services

Preservation services include service revenues from processing cardiac and vascular tissues. Our cardiac valves are primarily used in cardiac replacement and reconstruction surgeries, including the Ross procedure, for patients with endocarditis or congenital heart defects. Our cardiac tissues are primarily distributed in domestic markets. The majority of our vascular preservation services revenues are related to shipments of saphenous veins, which are mainly used in peripheral vascular reconstruction surgeries to avoid limb amputations. Competition with synthetic product alternatives and the availability of tissues for processing are key factors affecting revenue volume that can fluctuate from quarter to quarter. Our vascular tissues are primarily distributed in domestic markets.

We continue to evaluate modifications to our tissue processing procedures in an effort to improve tissue processing throughput, reduce costs, and maintain quality across our tissue processing business. Preservation services revenues, particularly revenues for certain high-demand cardiac tissues, can vary from quarter to quarter and year to year due to a variety of factors, including quantity and type of incoming tissues, yields of tissue through the preservation process, timing of receipt of donor information, timing of the release of tissues for implant, demand for certain tissue types due to the number and type of procedures being performed, and pressures from competing products or services.

In the fourth quarter of 2020 we became aware that a supplier shipped to us a saline solution lot that we use in our tissue processing that contained some contamination in a small number of bottles of the solution lot. The contamination was identified by our in-process quality controls. The contaminated solution was estimated to have impacted a small percentage of tissue processed with this solution lot, causing us to write-off approximately $826,000 of tissue in the fourth quarter of 2020. An additional $5.0 million of tissue was quarantined in process pending further testing. Upon completion and FDA acceptance of the testing, we began releasing tissue meeting our release criteria late in the second quarter of 2021. We believe that the written-off and quarantined tissue impacted the availability of tissue for distribution, which had a negative impact on revenue in the first quarter of 2021 and, to a lesser extent, the second quarter of 2021.

Revenues from tissue processing increased 8% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. The increase in revenues was primarily due to an increase of tissues shipped, which increased revenues by 5%, and an increase in average sales prices, which increased revenues by 3%.

The increase in revenues from tissue processing for the twelve months ended December 31, 2022 was primarily due to an increase in medical procedures that utilize our cardiac tissues.

Cost of Products and Preservation Services

Cost of Products

Twelve Months EndedDecember 31,

Cost of products increased 11% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. Cost of products for the twelve months ended December 31, 2022 and 2021 included costs related to aortic stent grafts, surgical sealants, On-X, and other products.

The increase in cost of products for the twelve months ended December 31, 2022 was primarily due to an increase in shipments of aortic stent grafts and On-X products as well as an increase in the cost of aortic stent grafts and BioGlue as compared to the twelve months ended December 31, 2021.

Table of Contents

Cost of Preservation Services

Twelve Months EndedDecember 31,

Cost of preservation services increased 8% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. Cost of preservation services included costs for cardiac and vascular tissue preservation services.

The increase in cost of preservation services for the twelve months ended December 31, 2022 was primarily due to an increase in shipments of cardiac tissue and an increase in the processing cost of cardiac and vascular tissues, partially offset by a decrease in shipments of vascular tissue, as compared to the twelve months ended December 31, 2021.

Gross Margin

Twelve Months EndedDecember 31,

Gross margin as a percentage of total revenues 65 % 66 %

Gross margin increased 3% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. The increase for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021 was primarily due to an increase in shipments of aortic stent grafts, On-X products, and preservation services, partially offset by the effect of foreign exchange rates and an increase in cost of certain products. Gross margin as a percentage of total revenues decreased for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021, primarily due to an increase in product costs of certain products sold resulting from inflationary pressures of materials and labor, and to a lesser extent, the mix of products shipped, partially offset by favorable pricing of certain products during the twelve months ended December 31, 2022.

Operating Expenses

General, Administrative, and Marketing Expenses

Twelve Months EndedDecember 31,

General, administrative, and marketing expenses $ 157,443 $ 169,774

General, administrative, and marketing expenses decreased 7% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. The decrease in General, administrative, and marketing expenses for the twelve months ended December 31, 2022 was primarily due to a decrease in business development expenses partially offset by personnel-related expenses, travel, and marketing.

General, administrative, and marketing expenses included $7.7 million of business development income for the twelve months ended December 31, 2022, as compared to $16.1 million of business development expense for the twelve months ended December 31, 2021.

Business development income during the twelve months ended December 31, 2022 included a $9.0 million fair value reduction for the contingent consideration related to Ascyrus Acquisition (“Ascyrus contingent consideration”) further described in Part II, Item 8, Note 3 of “Ascyrus Acquisition” of this form 10-K. Business development expenses during the twelve months ended December 31, 2021 included a $4.9 million expense related to the impairment of the Endospan Option further described in Part II, Item 8, Note 4 of “Endospan Agreements” of this form 10-K and $9.7 million expense related to an increase in the fair value of the Ascyrus contingent consideration.

Research and Development Expenses

Twelve Months EndedDecember 31,

Research and development expenses $ 38,879 $ 35,546

Research and development expenses as a percentage of total revenues 12 % 12 %

Research and development expenses increased 9% for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021. Research and development spending for the twelve months ended December 31, 2022 and 2021 was primarily focused on clinical work to gain regulatory approvals for On-X, certain aortic stent grafts, and PerClot products.

On September 23, 2022 we stopped the PROACT Xa clinical trial as recommended by the trial's independent Data and Safety Monitoring Board. The PROACT Xa clinical trial was a prospective, randomized, trial designed to determine if patients with On-X mechanical aortic valves could be maintained safely and effectively on apixaban rather than on warfarin. As a result of PROACT Xa's early termination, we recorded $4.5 million of termination and wind-down expenses that are included in Research and development operating expenses on the Consolidated Statements of Operations and Comprehensive Loss for the twelve months ended December 31, 2022. The majority of these costs include administrative costs that we paid during the fourth quarter of 2022 and anticipate paying during the first quarter of 2023, as well as the estimated cost of clinical drugs purchased for patients participating in the study that are not expected to be recovered.

Research and development expenses for the twelve months ended December 31, 2022 also include $1.9 million related to PerClot pre-launch inventory manufactured as part of the Baxter transaction.

Gain from Sale of Non-Financial Assets

Gain from sale of non-financial assets for the twelve months ended December 31, 2021 consisted of the net $15.9 million gain from the sale of PerClot assets as part of the Baxter Transaction on July 28, 2021.

Interest Expense

Interest expense was $18.2 million and $16.9 million for the twelve months ended December 31, 2022 and 2021, respectively. Interest expense for the twelve months ended December 31, 2022 and 2021 relates to interest on debt and uncertain tax positions.

Other Expense, Net

Other expense, net was $3.1 million and $6.1 million for the twelve months ended December 31, 2022 and 2021, respectively. Other expense, net for the twelve months ended December 31, 2022 primarily includes the realized and unrealized effects of foreign currency gains and losses. Other expense, net for the twelve months ended December 31, 2021 primarily includes realized and unrealized effects of foreign currency gains and losses and fair value adjustments of financial instruments.

Table of Contents

We incurred a loss before income taxes for the twelve months ended December 31, 2022 and 2021. The loss before income taxes for the twelve months ended December 31, 2022 was negatively impacted by an increase in certain operating expenses to support revenue expansion, and an increase in investments in the research and development pipeline. The loss before income taxes was partially offset by the change in fair value of the Ascyrus contingent consideration for the twelve months ended December 31, 2022. The loss before income taxes for the twelve months ended December 31, 2021 was primarily due to business development expenses primarily related to the Ascyrus contingent consideration and investments in the research and development pipeline. Revenues for the twelve months ended December 31, 2022 and 2021 were also unfavorably impacted by delays or cancellations of some surgical procedures as a result of reduced hospital capacity and staffing and hospital restrictions due to the COVID-19 pandemic in certain regions. The revenue impact from COVID-19 was smaller and varied regionally during the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021.

Our effective income tax rate was an expense of 28% for the twelve months ended December 31, 2022, as compared to break-even for the twelve months ended December 31, 2021. The change in the tax rate for the twelve months ended December 31, 2022 was primarily due to a decrease in the excess tax benefit related to stock compensation, an increase in the estimated current year valuation allowance, an increase in unfavorable prior year tax return true-ups, and an increase in the benefit related to uncertain tax position statute expirations for the twelve months ended December 31, 2022, as compared to the twelve months ended December 31, 2021.

Our income tax rate for the twelve months ended December 31, 2022 was primarily affected by an increase in the valuation allowance on current year items, nondeductible executive compensation expenses, and uncertain tax position expenses. These tax expenses were partially offset by the research and development tax credit.

Our income tax rate for the twelve months ended December 31, 2021 was primarily affected by an increase in the valuation allowance on current year items, foreign expense items, non-deductible executive compensation expenses, and the recording of a tax reserve on prior year items. These tax expenses were partially offset by the reduction of a valuation allowance on prior year items, the research and development tax credit, and releases of uncertain tax position liabilities.

We experienced a net loss and diluted loss per common share for the twelve months ended December 31, 2022 and 2021. Net loss and diluted loss per common share for the twelve months ended December 31, 2022 was primarily due to an increase in loss before income taxes, as discussed above.

Seasonality

As a result of the uncertainty and other impacts of the COVID-19 pandemic and the resulting shifts of timing in some revenue, our historically observable seasonality of revenues has been impacted or obscured in 2021 and 2022 and potentially beyond.

Historically, we believe the demand for most of our aortic stent grafts is seasonal, with a decline in demand generally occurring in the third quarter due to the summer holiday season in Europe. We are uncertain whether the demand for AMDS and NEXUS products is seasonal, as these products have not fully penetrated many markets and, therefore, the nature of any seasonal trends may not yet be obvious.

Historically, we believe the demand for BioGlue and On-X products is seasonal, with a decline in demand generally occurring in the third quarter followed by stronger demand in the fourth quarter. We believe that this trend may be due to the summer holiday season in Europe and the US.

We do not believe the demand for our other products is seasonal.

Demand for our cardiac preservation services has traditionally been seasonal, with peak demand generally occurring in the third quarter. We believe this trend for cardiac preservation services is primarily due to the high number of surgeries scheduled during the summer months for school-aged patients. Based on experience in recent years, we believe that this trend is lessening as we are distributing a higher percentage of our tissues for use in adult populations.

Demand for our vascular preservation services has also traditionally been seasonal, with lowest demand generally occurring in the fourth quarter. We believe this trend for vascular preservation services is primarily due to fewer vascular surgeries being scheduled during the winter holiday months.

Liquidity and Capital Resources

Net Working Capital

At December 31, 2022 net working capital (current assets of $247.3 million less current liabilities of $49.7 million) was $197.6 million, with a current ratio (current assets divided by current liabilities) of 5 to 1, as compared to net working capital of $202.7 million and a current ratio of 6 to 1 at December 31, 2021.

Overall Liquidity and Capital Resources

Our primary cash requirements for the twelve months ended December 31, 2022 were for general working capital needs, interest and principal payments under our Credit Agreement (defined below), interest payments under our Convertible Senior Notes (defined below), capital expenditures for facilities and equipment, and repurchases of stock to cover tax withholdings. We funded our cash requirements through our existing cash reserves, proceeds from stock option exercises, and the Baxter Transaction described above.

We believe our cash from operations and existing cash and cash equivalents will enable us to meet our current operational liquidity needs for at least the next twelve months. Our future cash requirements are expected to include interest and principal payments under our Credit Agreement and Convertible Senior Notes (described in “Significant Sources and Uses of Liquidity” section below), expenditures for clinical trials, research and development expenditures, general working capital needs, capital expenditures, and other corporate purposes and may include cash to fund business development activities including obligations in the Endospan and Ascyrus agreements. These items may have a significant effect on our future cash flows during the next twelve months. Subject to the terms of our Credit Agreement, we may seek additional borrowing capacity or financing, pursuant to our current or any future shelf registration statement, for general corporate purposes or to fund other future cash requirements. If we undertake any further significant business development activity, we may need to finance such activities by obtaining additional debt financing or using a registration statement to sell equity securities. There can be no assurance that we will be able to obtain any additional debt or equity financing at the time needed or that such financing will be available on terms that are favorable or acceptable to us.

Significant Sources and Uses of Liquidity

On December 1, 2017 we entered into a credit and guaranty agreement for a $255.0 million senior secured credit facility, consisting of a $225.0 million secured term loan facility (the “Term Loan Facility”) and a $30.0 million secured revolving credit facility (the "Revolving Credit Facility” and, together with the Term Loan Facility, the “Credit Agreement”). We and each of our existing domestic subsidiaries (subject to certain exceptions and exclusions) guarantee the obligations under the Credit Agreement (the “Guarantors”). The Credit Agreement is secured by a security interest in substantially all existing and after-acquired real and personal property (subject to certain exceptions and exclusions) of us and the Guarantors.

On June 2, 2021 we entered into an amendment to our Credit Agreement to extend the maturity dates of both the Company’s Term Loan and its Revolving Credit Facility. As part of the amendment, the maturity dates of both the Company’s Term Loan and its Revolving Credit Facility were each extended by two and one-half years, until June 1, 2027 and June 1, 2025, respectively, subject to earlier springing maturities if our 4.25% Convertible Senior Notes, described below, remain outstanding on April 1, 2025 and December 31, 2024, respectively. With respect to the Term Loan, if the Convertible Senior Notes remain outstanding on April 1, 2025, the Term Loan’s maturity date will be April 1, 2025, or, if the Convertible Senior Notes’ own maturity date has been extended, the earlier of (i) 91 days prior to the Convertible Senior Notes’ new maturity date and (ii) June 1, 2027. In the case of the Revolving Credit Facility, if the Convertible Senior Notes are still outstanding on December 31, 2024, the Revolving Credit Facility’s maturity date will be either December 31, 2024 or, if the Convertible Senior Notes’ own maturity date has been extended, the earlier of (i) 182 days prior to the Convertible Senior Notes’ new maturity date and (ii) June 1, 2025. Under the amendment, the Term Loan Facility bears interest, at our option, at a floating annual rate equal to either the base rate, plus a margin of 2.50%, or LIBOR, plus a margin of 3.50%. Prior to the amendment, the optional floating annual rate was equal to either the base rate plus a margin of 2.25%, or LIBOR, plus a margin of 3.25%.

On December 19, 2022 in accordance with adopting ASU 2020-04 and 2021-01, we entered into an amendment to our Credit Agreement to replace the LIBOR based benchmark interest rate with the Secured Overnight Financing Rate (“SOFR”) based benchmark interest rate for our Term Loan Facility and our Revolving Credit Facility. Based on historical analysis of the differences between the benchmark rates, SOFR is adjusted to arrive at a Term SOFR rate that serves as the replacement base rate for LIBOR under our amended credit facilities. Under this amendment, at the maturity of our existing LIBOR-based loan on December 30, 2022, the interest rate at the repricing of our Term Loan Facility was calculated as Term SOFR plus a fixed percentage credit spread of 3.50%. The loan under the Revolving Credit Facility bears interest at Term SOFR plus a margin of between 4.00% and 4.25%, depending on our consolidated leverage ratio. As of December 31, 2022 the aggregate interest rate of the Credit Agreement was 8.34% per annum.

On June 18, 2020 we issued $100.0 million aggregate principal amount of 4.25% Convertible Senior Notes with a maturity date of July 1, 2025 (the “Convertible Senior Notes”). The net proceeds from this offering, after deducting initial purchasers’ discounts and costs directly related to this offering, were approximately $96.5 million. On January 1, 2021 we adopted ASU 2020-06 and adjusted the carrying balance of the Convertible Senior Notes to notional. The Convertible Senior Notes balance was $100.0 million recorded in Long-term debt on the Consolidated Balance Sheets as of December 31, 2021. The Convertible Senior Notes may be settled in cash, stock, or a combination thereof, solely at our discretion. The initial conversion rate of the Convertible Senior Notes is 42.6203 shares per $1,000 principal amount, which is equivalent to a conversion price of approximately $23.46 per share, subject to adjustments. We use the if-converted method for assumed conversion of the Convertible Senior Notes for the diluted earnings per share calculation. The fair value and the effective interest rate of the Convertible Senior Notes as of December 31, 2022 was approximately $87.6 million and 5.05%, respectively. The fair value was based on market prices observable for similar instruments and is considered Level 2 in the fair value hierarchy.

The interest expense recognized on the Convertible Senior Notes includes approximately $4.9 million for the aggregate of the contractual coupon interest and the amortization of the debt issuance during the twelve months ended December 31, 2022 and 2021. Interest on the Convertible Senior Notes began accruing upon issuance and is payable semi-annually.

Holders of the Convertible Senior Notes may convert their notes at their option at any time prior to January 1, 2025 but only under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on September 30, 2020 (and only during such calendar quarter), if the last reported sale price of our 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; (ii) during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; (iii) we give a notice of redemption with respect to any or all of the notes, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or (iv) upon the occurrence of specified corporate events. On or after January 1, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time, regardless of the foregoing circumstances.

We cannot redeem the Convertible Senior Notes before July 5, 2023. We can redeem them on or after July 5, 2023, in whole or in part, at our option, if the last reported sale price per share of our common stock has been at least 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 we provide notice of redemption. We may redeem for cash all or part of the Convertible Senior Notes at a redemption price equal to 100% of the principal amount of the redeemable Convertible Senior Notes, plus accrued and unpaid interest to, but excluding, the redemption date. No principal payments are due on the Convertible Senior Notes prior to maturity. Other than restrictions relating to certain fundamental changes and consolidations, mergers or asset sales and customary anti-dilution adjustments, the Convertible Senior Notes do not contain any financial covenants and do not restrict us from conducting significant restructuring transactions or issuing or repurchasing any of its other securities.

We have benefited from various aspects of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) including a decrease in the amount of interest expense limitation in 2020 and the deferment of a portion of the 2020 employer’s portion of social security tax into 2021 and 2022.

As of December 31, 2022 approximately 40% of our cash and cash equivalents were held in foreign jurisdictions.

The following table summarizes cash flows from operating activities, investing activities and financing activities for the periods indicated (in thousands):

Year Ended December 31,

Cash flows (used in) provided by:

Effect of exchange rate changes on cash and cash equivalents 1,848 2,200

Decrease in cash and cash equivalents $ (15,659) $ (6,948)

Net Cash Flows from Operating Activities

Net cash used in operating activities was $5.2 million and $2.6 million for the twelve months ended December 31, 2022 and 2021, respectively.

We use the indirect method to prepare our cash flow statement, and accordingly, the operating cash flows are based on our net loss, which is then adjusted to remove non-cash items, items classified as investing and financing cash flows, and for changes in operating assets and liabilities from the prior year end. For the twelve months ended December 31, 2022 these non-cash items primarily included $22.4 million in depreciation and amortization expenses, $12.3 million in non-cash compensation, $9.0 million in fair value adjustments of financial instruments, $7.4 million in non-cash lease expense, and $1.7 million of deferred income tax changes.

Our working capital needs, or changes in operating assets and liabilities, also affected cash from operations. For the twelve months ended December 31, 2022 these changes included the unfavorable effect of $13.3 million due to the timing differences between recording receivables and the receipt of cash, $8.4 million due to an increase in inventory balances and deferred preservation costs, $2.2 million due to an increase in prepaid expenses and other assets, and $2.0 million due to the timing differences between the recording of accounts payable and other current liabilities.

Net Cash Flows from Investing Activities

Net cash used in investing activities was $10.7 million for the twelve months ended December 31, 2022, as compared to net cash provided by investing activities of $5.7 million for the twelve months ended December 31, 2021. During the twelve months ended December 31, 2022 cash flows used in investing activities primarily included $9.0 million of cash used for capital expenditures. During the twelve months ended December 31, 2021 cash flows provided by investing activities included $19.0 million of net proceeds from the sale of non-financial assets, partially offset by $13.1 million of cash used for capital expenditures.

Net Cash Flows from Financing Activities

Net cash used in financing activities was $1.6 million and $12.2 million for the twelve months ended December 31, 2022 and 2021, respectively. The current year cash used in financing activities was primarily due to $2.8 million repayment of debt and $1.8 million for repurchases of common stock to cover tax withholdings, partially offset by $3.4 million of proceeds from exercise of stock options and issuances of common stock.

Scheduled Contractual Obligations and Future Payments

Our long-term debt obligations and interest payments include $314.8 million of scheduled principal payments and $89.7 million in anticipated interest payments related to our Credit Agreement, Convertible Senior Notes, and other governmental loans.

We have contingent payment obligations that include up to $100.0 million to be paid to the former shareholders of Ascyrus, upon the achievement of certain milestones. We are obliged to make a $5.0 million third tranche payment under our loan agreement with Endospan upon receipt of certification that certain clinical trial milestones have been achieved. See “Overview” identified in Part II, Item 8, Note 3 of the “Notes to Consolidated Financial Statements” of this Form 10-K.

Table of Contents

As part of the Baxter Transaction, we may be required to pay up to $7.5 million to SMI if certain milestones are met. See “Overview” identified in Part II, Item 8, Note 2 of the “Notes to Consolidated Financial Statements” of this Form 10-K.

Our operating and finance lease obligations result from the lease of land and buildings that comprise our corporate headquarters and our various manufacturing facilities, leases related to additional manufacturing, office, and warehouse space, leases on company vehicles, and leases on a variety of office equipment and other equipment.

Capital Expenditures

Capital expenditures for the twelve months ended December 31, 2022 and 2021 were $9.0 million and $13.1 million, respectively. Capital expenditures in the twelve months ended December 31, 2022 were primarily related to computer software, routine purchases of manufacturing and tissue processing equipment, leasehold improvements needed to support our business, and computer equipment.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk

Our interest income and interest expense are sensitive to changes in the general level of US interest rates. In this regard, changes in US interest rates affect the interest earned on our cash and cash equivalents of $39.4 million as of December 31, 2022, and interest paid on the outstanding balances, if any, of our variable rate Revolving Credit Facility, Term Loan Facility, and Convertible Senior Notes. A 10% adverse change in interest rates, as compared to the rates experienced by us in the twelve months ended December 31, 2022 affecting our cash and cash equivalents, Term Loan Facility, Revolving Credit Facility, and Convertible Senior Notes would not have had a material impact on our financial position, profitability, or cash flows.

Foreign Currency Exchange Rate Risk

We have balances, such as cash, accounts receivable, accounts payable, and accruals that are denominated in foreign currencies. These foreign currency denominated balances are sensitive to changes in exchange rates. In this regard, changes in exchange rates could cause a change in the US Dollar equivalent of cash or funds that we will receive in payment for assets or that we would have to pay to settle liabilities. As a result, we could be required to record these changes as gains or losses on foreign currency translation. Realized and unrealized gains and losses were a loss of $3.1 million, loss of $5.5 million, and a gain of $1.9 million, for the years ended December 31, 2022, 2021, and 2020, respectively.

We have revenues and expenses that are denominated in foreign currencies. Specifically, a portion of our international aortic stent and stent grafts, surgical sealants, On-X, and other product revenues are denominated in Euros, British Pounds, Swiss Francs, Polish Zlotys, Canadian Dollars, and Brazilian Reals and a portion of our General, administrative, and marketing expenses are denominated in Euros, British Pounds, Swiss Francs, Polish Zlotys, Canadian Dollars, Brazilian Reals, and Singapore Dollars. These foreign currency transactions are sensitive to changes in exchange rates. In this regard, changes in exchange rates could cause a change in the US Dollar equivalent of net income from transactions conducted in other currencies. As a result, we could recognize a reduction in revenues or an increase in expenses related to a change in exchange rates.

An additional 10% adverse change in exchange rates from the exchange rates in effect on December 31, 2022 could impact our financial position or cash flows by approximately $7.0 million. An additional 10% adverse change in exchange rates from the weighted-average exchange rates experienced by us for the twelve months ended December 31, 2022 affecting our revenue and expense transactions denominated in foreign currencies, would not have had a material impact on our financial position or profitability.

Management’s Report on Internal Controls over Financial Reporting

The management of Artivion, Inc. and subsidiaries (“Artivion” or “we”) is responsible for establishing and maintaining adequate internal controls over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. Artivion’s internal control system was designed to provide reasonable assurance to Artivion’s management and Board of Directors regarding the preparation and fair presentation of published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. 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.

Artivion management assessed the effectiveness of Artivion’s internal controls over financial reporting as of December 31, 2022. In making this assessment, we used the criteria set forth in the Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this assessment, we have determined that, as of December 31, 2022, our internal controls over financial reporting was effective based on those criteria.

Artivion’s independent registered public accounting firm, Ernst & Young, LLP, has issued an audit report on the effectiveness of Artivion’s internal controls over financial reporting as of December 31, 2022.
