PRODUCTS

Our product offerings fall within two segments, Med Tech and Med Device. All products discussed below have been cleared for sale in the United States by the Food and Drug Administration. International regulatory clearances vary by product and jurisdiction.

Med Tech

Auryon

The Auryon Atherectomy System is one of our latest advancements in peripheral arterial disease. The Auryon system is designed to deliver an optimized wavelength and short pulse width to remove lesions while preserving the vessel wall endothelium. Additionally, the Auryon system features integrated aspiration which enhances the safety of the procedure. Regardless of lesion type or location - whether above or below the knee - the Auryon system provides safety, efficacy and versatility, supporting femoral, pedal or radial access. The Auryon system is indicated for use in the treatment, including atherectomy, of infrainguinal stenoses and occlusions, including in-stent restenosis (ISR), and to aspirate thrombus adjacent to stenoses in native and stented infrainguinal arteries.

Thrombectomy

Our Thrombus Management portfolio includes the AlphaVac Mechanical Thrombectomy System, AngioVac venous drainage cannula and circuit, as well as catheter directed thrombolytic devices, including the Uni-Fuse system and the Uni-Fuse+ system. AngioDynamics offers a range of options when treating thrombus and removing fresh, soft thrombi or emboli.

AngioVac

Our AngioVac venous drainage system includes a Venous Drainage Cannula and Extracorporeal Circuit. The cannula is indicated for use as a venous drainage cannula and for removal of fresh, soft thrombi or emboli during extracorporeal bypass. The AngioVac circuit is indicated for use in procedures requiring extracorporeal circulatory support for periods of up to six hours. AngioVac devices are for use with other manufacturers’ off-the-shelf pump, filter and reinfusion cannula, to facilitate venous drainage as part of an extracorporeal bypass procedure.

The AngioVac venous drainage cannula is a 22 French flat coil-reinforced cannula designed with a proprietary self-expanding nitinol reinforced funnel shaped distal tip. The funnel shaped tip enhances venous drainage flow when the distal tip is exposed by retracting the sheath, helps prevent clogging of the cannula with commonly encountered undesirable intravascular material, and facilitates embolic removal of such extraneous material.

AlphaVac

The AlphaVac System is an emergent mechanical aspiration device that eliminates the need for perfusionist support. AlphaVac is offered in both a 22 French flat coil-reinforced cannula and an 18 French braided reinforced cannula each designed with a proprietary self-expanding nitinol reinforced funnel shaped distal tip. AlphaVac is indicated for the non-surgical removal of thrombi or emboli from vasculature as well as aspiration of contrast media and other fluids from the vasculature. The cannula is intended for use in the venous system. The handle is indicated as a vacuum source for the AlphaVac MMA system. The AlphaVac F18 system is indicated for the treatment of pulmonary embolism and allows for the utilization in the non-surgical removal of thrombi or emboli from the venous vasculature, reducing thrombus burden and improving right ventricular function in patients with PE.

Thrombolytic Catheters

Thrombolytic catheters are used to deliver thrombolytic agents, which are drugs that dissolve blood clots in hemodialysis access grafts, arteries, veins and surgical bypass grafts. AngioDynamics’ Uni-Fuse infusion catheter features pressure response outlets, a proprietary slit technology that provides a consistent, even distribution of fluid volume along the entire length of the infusion pattern, designed to provide an advantage over standard side-hole catheters.

We also offer the Pulse-Spray infusion system for high pressure, pulsed delivery of lytic agents designed to shorten treatment time, and the SpeedLyser infusion system built for dialysis grafts and fistulas.

NanoKnife

The NanoKnife IRE Ablation System is an alternative to traditional thermal ablation that received 510(k) clearance from the Food and Drug Administration for the surgical ablation of soft tissue. The system utilizes low energy direct current electrical pulses to permanently open pores in target cell membranes. These permanent pores or nano-scale defects in the cell membranes result in cell death. The treated tissue is then removed by the body’s natural processes in a matter of weeks, mimicking natural cell death. Unlike other ablation technologies, the NanoKnife System does not achieve tissue ablation using thermal energy.

The NanoKnife System consists of two major components: a Low Energy Direct Current, or LEDC Generator and needle-like electrode probes. Up to six (6) electrode probes can be placed into or around the targeted soft tissue. Once the probes are in place, the user enters the appropriate parameters for voltage, number of pulses, interval between pulses, and the pulse length into the generator user interface. The generator then delivers a series of short electric pulses between each electrode probe. Full paralytic anesthesiology is required for safe IRE delivery.

In December 2024, the NanoKnife System received expanded FDA 510(k) clearance for the ablation of prostate tissue which broadens treatment options for men and reinforces the system’s strong safety and efficacy profile.

Med Device

Peripheral Products (Interventional Devices)

We offer a comprehensive portfolio of products for use during minimally invasive procedures. Product categories include an extensive line of angiographic catheters, guidewires, drainage catheters and micropuncture kits.

Angiographic Catheters & Guidewires

Our extensive line of various angiographic catheter configurations are designed to allow physicians to navigate and reach targeted anatomical locations within a patient’s vasculature that are in need of angiographic diagnosis.Typically run over a diagnostic guidewire, our angiographic catheters allow physicians to deliver contrast media to the desired location to determine the diagnosis and subsequent therapeutic modalities, as needed for the patient.

AngioDynamics offers three different angiographic catheter lines to meet physicians’ procedural needs. All of our catheters feature our soft, atraumatic, super-radiopaque tip that is uniquely welded to our co-extruded nylon shaft, which provides excellent visibility under fluoroscopy and re-enforced tip stability.

•Soft-Vu Angiographic Catheters highlight the soft, atraumatic super-radiopaque and proprietary tip-to-shaft weld in a full offering of different tip shapes, lengths and French sized flush and selective catheters. Flush catheters are used in procedures where a large volume of contrast is required to deliver a concentrated bolus of contrast quickly for visualization or larger anatomical locations, such as the aorta or for run-offs into lower extremities. Selective catheters are typically used to gain access to more specific vasculature within the body to deliver smaller amounts of contrast.

•Mariner Hydrophilic Catheters also feature a hydrophilic coating on the distal 20cm of the catheter that reduces friction during catheter advancement in the vasculature and allows for smooth navigation, as well as, optimum handling and control by the physician.

•Accu-Vu Sizing Catheters are our line of flush catheters that also feature highly visible radiopaque marker bands, which are heat embedded, along the catheter shaft, providing a smooth transition across the catheter shaft to ensure the marker bands will not separate from the shaft. These radiopaque marker bands come in different patterns along the shaft and allow physicians, under fluoroscopy, to take measurements in different anatomical locations for the placement of stents, IVC filters or other devices. The tight tolerances and consistent placement across the entire sizing pattern, within +/-1mm of accuracy, provide a highly accurate measurement to the physician.

AngioDynamics offers a line of diagnostic and interventional guidewires which are designed to aid in delivering diagnostic and/or therapeutic devices to the desired location.

•The ADx Peripheral Vascular Guidewire line is AngioDynamics diagnostic line of guidewires that is available in a multitude of fixed core wire configurations, including J-Tip and Bentson, in various lengths and outer diameters (OD). By utilizing a proprietary pre-coat process for the Polytetrafluoroethylene (PTFE) and upholding tight specifications, our ADx Guidewires offer high quality and performance for physicians.

•The NiT-Vu High Performance Micro Guidewires are our highly kink resistant nitinol shaft interventional wires that feature a highly visible radiopaque tungsten tip and lubricious coating. The NiT-Vu wires are designed to reduce friction during wire advancement and also provides torque control, flexibility and kink resistance.

Drainage Products

To aid physicians in percutaneous drainage procedures, AngioDynamics offers the Total Abscession Drainage Catheters. The Total Abscession Drainage Catheter is available in Multipurpose/General and Biliary configurations, and also offers a Nephrostomy option. The portfolio offers options with a radiopaque marker band at the distal tip to aid in placement.

•The Total Abscession Drainage Catheter line offers a soft, kink resistant shaft that features the lubricious Blue Silk Finish for easier insertion and pushability, while providing the optimal patient comfort. The unique Vault Locking Mechanism securely fixes the pigtail and prevents tampering or accidental removal.

Micropuncture Kits

AngioDynamics offers physicians two micropuncture kit lines that are designed to start each procedure with ease and efficiency: Mini Stick MAX Coaxial Microintroducer Kits and Micro-Introducer Kits. Each kit features a coaxial design with a 4F or 5F sheath introducer and stiff or standard dilator, along with a 21G needle and various 0.018” access wire configurations.

•Mini Stick MAX Coaxial Introducer kits contain a unique containment clip that keeps all the unique components of the kit together and organized. The kit options include our AngioDynamics proprietary coaxial introducer with smooth transition at the tip, translucent 21G needle with bevel indicator and 0.018” access wire available in three different wire material configurations.

•The Micro-Introducer Kits offer a variety of configurations that aid in simplifying set up and gaining vascular access.

Ports

Ports are implantable devices utilized for the central venous administration of a variety of medical therapies and for blood sampling and diagnostic purposes. Central venous access facilitates a more systemic delivery of treatment agents, while mitigating certain harsh side effects of certain treatment protocols and eliminating the need for repeated access to peripheral veins. Depending upon needle gauge size and the port size, a port can be utilized for up to approximately 2,000 accesses once implanted in the body. Our ports are used primarily in systemic or regional short- and long-term cancer treatment protocols that require frequent infusions of highly concentrated or toxic medications (such as chemotherapy agents, antibiotics or analgesics) and frequent blood samplings. Our port products and accessories include:

•SmartPort, SmartPort+, SmartPort Plastic: The SmartPort power-injectable port with Vortex technology offers the ability for a clinician to access a vein for both the delivery of medications or fluids and for administering power-injected contrast to perform a CT scan. The ability to access a port for power-injected contrast studies eliminates the need for additional needle sticks in the patient’s arm and wrist veins. Once implanted, repeated access to the bloodstream can be accomplished with greater ease and less discomfort. Our SmartPort port line is available in standard, mini and low-profile to accommodate more patient anatomies. The SmartPort+ port line combines Vortex technology with BioFlo catheters. In addition to the three titanium port body sizes, there is a plastic port body.

•BioFlo Port: Our BioFlo Port was the first port available featuring a catheter with Endexo Technology. Advanced features of the BioFlo Port include multiple profile and catheter options, a large septum area for ease of access, PASV and non-PASV valve technology and the ability to administer contrast through a CT injection for purposes of imaging. The BioFlo port family is available in single or dual lumen configurations.

•Xcela Plus: The Xcela Plus Port product family is Power-Injectable and part of a complete portfolio of vascular access products, and is fully compatible with the LifeGuard Safety Infusion product family. It has easily identifiable critical information radiopaque “CT” lettering which helps to confirm if port is power-injectable or flipped. The Xcela Plus port family is available in single lumen standard size in either a non-valved or valved configuration.

Port Technologies

•BioFlo Endexo: AngioDynamics offers the BioFlo catheter, the only catheter on the market with Endexo Technology, a material more resistant to thrombus accumulation, in vitro (based on platelet count). Endexo Technology is a permanent and non-eluting polymer that is “blended” into the polyurethane from which the catheter is made. It is present throughout the catheter, including the extraluminal, intraluminal and cut catheter surface of the tip. Endexo Technology remains present for the life of the catheter. The BioFlo catheter’s long-term durability and efficacy is intended to provide clinicians a high degree of safety and confidence in providing better patient care and improved patient outcomes.

•Vortex: Our Vortex port technology line of ports features a clear-flow port technology that, we believe, revolutionized port design. With its rounded chamber, the Vortex port is designed to have no sludge-harboring corners or dead spaces. This product line consists of titanium, plastic and dual-lumen offerings.

•PASV Valve Technology: The PASV Valve Technology is designed to automatically resist backflow and reduce blood reflux that could lead to catheter-related complications.

Venous Insufficiency

VenaCure EVLT laser system

Our VenaCure EVLT system products are used in endovascular laser procedures to treat superficial venous disease (varicose veins). Superficial venous disease is a malfunction of one or more valves in the leg veins whereby blood refluxes or does not return to the heart, thereby pooling in the legs and leading to symptoms such as pain, swelling and ulcerations. The VenaCure EVLT system uses laser energy to stop the reflux by ablating (collapsing and destroying) the affected vein. Blood is then re-routed to other healthy veins.

The procedure is minimally invasive and generally takes less than an hour, typically allowing the patient to quickly return to normal activities.

The VenaCure EVLT system is sold as a system that includes diode laser hardware and procedure kits which include disposable laser fiber components, an access sheath, access wires and needles. Our VenaCure EVLT 1470 nanometer wavelength laser allows physicians to more efficiently heat the vein wall using lower power settings thereby reducing the risk of collateral damage. The NeverTouch tip fiber eliminates laser tip contact with the vein wall, which in turn minimizes perforations of the vein wall that typically result in less pain and bruising as compared to traditional bare-tip fibers. The NeverTouch tip also maximizes ultrasonic visibility, making it easier for physicians to use. Procedure kits are available in a variety of lengths and configurations to accommodate varied patient anatomies.

NeverTouch and NeverTouch Direct gold-tip laser fibers, is an integral part of AngioDynamics’ advanced varicose vein treatment and establishes a new standard for patient comfort, visibility and ease of use. The innovation behind the NeverTouch tip is a glass weld at the distal tip. This glass weld tip technology has less focal charring of the vein wall versus a bar-tip fiber. The NeverTouch procedure kit is available in 25cm, 45cm, 65cm, and 90cm lengths. It is also available with an .018” access system, which eliminates the need for a 5F micro-access sheath and the need to exchange wires and size up, resulting in few procedure steps, and may result in faster procedure time.

The 400 Micron Perforator & Accessory Vein Ablation kit (PVAK) is an AngioDynamics VenaCure EVLT endovenous laser vein treatment offering that provides patients a minimally-invasive choice for treating the source of their varicose veins. The PVAK kit may also provide patients a potentially quicker recovery and return to normal daily routines, as compared to surgical stripping. The PVAK kit allows for simple access and accurate positioning. The smaller fiber aids in access and positioning for deep and saphenous veins. The 21G venous access needle ensures easy, atraumatic access and the .018” guidewire navigates small, tortuous veins with a floppy tip and has a firm anchor to guide the sheath and hold it in place.

Microwave Ablation

Solero Microwave Tissue Ablation (MTA) System

The Solero MTA System features the Solero Microwave (MW) Generator and the specially designed Solero MW Applicators. The solid state Solero MW Generator with a 2.45 GHz operating frequency can power up to 140W for optimized power delivery and fast ablations. The Solero MW Applicator’s patented dipole array and ceramic tip tuning diffuses MW energy nearly spherically, and its patented cooling channel with thermocouple provides real-time monitoring to help protect non-targeted tissue during the ablation. In addition, the Solero MTA System offers physicians scalability with a single applicator designed for multiple, predictable ablation volumes by varying time and wattage. Solero is a single applicator system able to complete up to a 5 cm ablation in six (6) minutes at maximum power. It is designed for open, laparoscopic and percutaneous ablation of soft tissue masses.

The Solero MTA System and Accessories are indicated for the ablation of soft tissue during open procedures. The Solero MTA System is not intended for cardiac use.

IsoLoc Endorectal Balloon

The IsoLoc Endorectal Balloon's unique, customer-driven design is the result of collaborations with Radiation Oncologists, Therapists and Physicists with one goal in mind, to create a new standard for endorectal balloons (ERB) in the oncology space.

The design of the IsoLoc device not only addresses patient comfort, but also simplifies three challenging clinical scenarios that many physicians face when using radiation therapy for and/or in relation to the prostate. First, its' gas-release tip removes rectal gas and reduces prostate motion for gaseous patients. Secondly, the structure of the ERB aids in defining the anatomy for difficult planning scenarios with post-radical patients. Lastly, the IsoLoc device repositions and lifts the bowel in patients that have a low-lying bowel.

Alatus Vaginal Balloon Packing System

The Alatus device was developed with the patient's comfort in mind and to assist the physician to move healthy tissue away from the radiation treatment field. Prior to the Alatus device, the clinician would push gauze into the vagina to move the bladder and bowel away from the radiation treatment field. Inserting gauze into the vagina can be uncomfortable before treatment and unpleasant at the end of treatment as it tends to dry out before removing.

RESEARCH & DEVELOPMENT

Our growth depends in large part on the continuous introduction of new and innovative products, together with ongoing enhancements to our existing products. This happens through internal product development, technology licensing, strategic alliances and acquisitions. Our research and development (R&D) teams work closely with our marketing teams, sales force and regulatory and compliance teams to incorporate customer feedback into our development and design process. We believe that we have a reputation among interventional physicians as a strong partner for developing high quality products because of our tradition of close physician collaboration, dedicated market focus, responsiveness and execution capabilities for product development and commercialization. We recognize the importance of, and intend to continue to make investments in R&D.

COMPETITION

We encounter significant competition across our product lines and in each market in which our products are sold. These markets are characterized by rapid change resulting from technological advances, scientific discoveries and changing customer needs and expectations. We face competitors, ranging from large manufacturers with multiple business lines, to small manufacturers that offer a limited selection of products.

Our primary competitors include: Boston Scientific Corporation; Cook Medical; Medical Components, Inc. (MedComp); TeleFlex Medical; Becton Dickinson; Medtronic; Merit Medical; Terumo Medical Corporation; Johnson and Johnson; Philips Healthcare; Stryker Corporation; Penumbra, Inc.; Varian Medical Systems; Abbott Laboratories and Total Vein Systems.

We believe our products compete primarily based on their quality, clinical outcomes, ease of use, reliability, physician familiarity and cost-effectiveness. In the current environment of managed care, which is characterized by economically motivated buyers, consolidation among health care providers, increased competition and declining reimbursement rates, we have been increasingly required to compete on the basis of price. We believe that our continued competitive success will depend upon our ability to develop or acquire scientifically advanced technology, apply our technology cost-effectively across product lines and markets, attract and retain skilled personnel, obtain patent or other protection for our products, obtain required regulatory and reimbursement approvals, manufacture and successfully market our products either directly or through third parties, and maintain sufficient inventory to meet customer demand.

SALES AND MARKETING

We sell our broad line of quality devices in the United States primarily through a direct sales force and internationally through a combination of direct sales and distributor relationships. We support our customers and sales organization with a marketing staff that includes product managers, customer service representatives and other marketing specialists. We focus our sales and marketing efforts on interventional radiologists, interventional cardiologists, vascular surgeons, urologists, interventional and surgical oncologists and critical care nurses.

MANUFACTURING

We manufacture certain proprietary components and products and then assemble, inspect, test and package our finished products. By designing and manufacturing many of our products from raw materials, and assembling and testing our subassemblies and products, we believe that we are able to maintain better quality control, ensure compliance with applicable regulatory standards and our internal specifications, and limit outside access to our proprietary technology. We have custom-designed proprietary manufacturing and processing equipment and have developed proprietary enhancements for existing production machinery.

We manufacture many of our products from two leased manufacturing properties, one in Queensbury, NY and one small facility in Glens Falls, NY, providing capabilities which include manufacturing, service, offices, engineering and research and we lease distribution warehouses. The manufacturing facilities are registered with the FDA and have been certified to ISO 13485 standards. ISO 13485 is a quality system standard that satisfies European Union regulatory requirements, thus allowing us to market and sell our products in European Union countries. AngioDynamics is certified under the Medical Device Single Audit Program ("MDSAP") which allows a recognized auditing organization to conduct a single regulatory audit of a medical device manufacturer to satisfy the relevant requirements of the regulatory authorities participating in the program. International partners that are participating in the MDSAP include:

•Therapeutic Goods Administration of Australia

•Brazil’s Agência Nacional de Vigilância Sanitária

•Health Canada

•Japan’s Ministry of Health, Labour and Welfare, and the Japanese Pharmaceuticals and Medical Devices Agency

•U.S. Food and Drug Administration

Our manufacturing facilities are subject to periodic inspections by regulatory authorities to ensure compliance with domestic and non-U.S. regulatory requirements. See “Government Regulation” section of this Item 1 for additional information. See Part I, Item 2 "Properties" in this Annual Report on Form 10-K for details on each manufacturing location.

AngioDynamics entered into a supply agreement with Biomerics (previously Precision Concepts) in Alajuela, Costa Rica. Biomerics is manufacturing, storing, and handling certain products for the Company and is registered with the FDA and certified to the ISO 13485 standard. The Company also relies on other third party manufacturers for the manufacturing of certain products.

On January 5, 2024, the Company announced a restructuring to optimize its manufacturing efficiency, capabilities and footprint (the "Plan"). In the second quarter of fiscal year 2025, the Company announced a modification to the Plan to maintain a presence in Queensbury, NY for the manufacturing of select products, customer service, logistics, shipping, quality and regulatory operations. The restructuring activities associated with the modified Plan are still expected to be completed in the third quarter of fiscal year 2026.

BACKLOG

We seek to maintain sufficient inventory on hand to ship product within 24-48 hours of order receipt to meet customer demand, and accordingly our backlog is not significant. As we shift additional manufacturing to Costa Rica and/or other manufacturing partners, we have built sufficient safety stock to reduce the risk of backlog during the transition.

INTELLECTUAL PROPERTY

Patents, trademarks and other proprietary rights are very important to our business. We also rely upon trade secrets, manufacturing know-how, technological innovations and licensing opportunities to maintain and improve our competitive position. We regularly monitor and review third-party proprietary rights, including patents and patent applications, as available, to aid in the development of our intellectual property strategy, avoid infringement of third-party proprietary rights, and identify licensing opportunities. The Company owns an extensive portfolio of patents and patent applications in the United States and in certain foreign countries. The portfolio also includes exclusive licenses to third party patents and applications. Most of our products are sold under the AngioDynamics trade name or trademark. Additionally, products are sold under product trademarks and/or registered product trademarks owned by AngioDynamics, Inc., or an affiliate or subsidiary. Some products contain trademarks of companies other than AngioDynamics.

See Part I, Item 3 "Legal Proceedings" and Note 17 to the consolidated financial statements in this Annual Report on Form 10-K for additional details on litigation regarding proprietary technology.

LITIGATION

We operate in an industry characterized by extensive patent litigation. Patent litigation can result in significant damage awards and injunctions that could prevent the manufacture and sale of affected products, or result in significant royalty payments in order to continue selling those products. The medical device industry is also susceptible to significant product liability claims. These claims may be brought by individuals seeking relief on their own behalf or purporting to represent a class. In addition, product liability claims may be asserted against us in the future based on events we are not aware of at the present time. At any given time, we are involved in a number of product liability actions. For additional information, see both Part I, Item 3 "Legal Proceedings" and Note 17 to the consolidated financial statements in this Annual Report on Form 10-K.

GOVERNMENT REGULATION

The products we manufacture and market are subject to regulation by the United States Food and Drug Administration (FDA) under the Federal Food, Drug, and Cosmetic Act, or FDCA, and international regulations in our specific target markets.

United States FDA Regulation

Before a new medical device can be introduced into the market, a manufacturer generally must obtain marketing clearance or approval from the FDA through either a 510(k) submission (a premarket notification) or a premarket approval application (PMA).

The 510(k) clearance procedure is available only if a manufacturer can establish that its device is “substantially equivalent” in intended use and in safety and effectiveness to a “predicate device,” which is (i) a device that has been cleared through the 510(k) clearance process; (ii) a device that was legally marketed prior to May 28, 1976 (preamendment device); or (iii) a device that was originally on the U.S. market as a Class III device (Premarket approval) and later downclassified to Class II or I. After a device receives 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, requires a new 510(k) clearance. The 510(k) clearance procedure including questions and responses may take up to 12 months. In some cases, supporting clinical data may be required. The FDA may determine that a new or modified device is not substantially equivalent to a predicate device or may require that additional information, including clinical data, be submitted before a determination is made, either of which could significantly delay the introduction of a new or modified device. If a device cannot demonstrate substantial equivalence, it may be subject to either a De Novo 510(k) submission or a PMA.

The PMA application procedure is more comprehensive than the 510(k) procedure and typically takes more time to complete. The PMA application must be supported by scientific evidence providing pre-clinical and clinical data relating to the safety and efficacy of the device and must include other information about the device and its components, design, manufacturing, and labeling. The FDA will approve a PMA application only if reasonable assurance that the device is safe and effective for its intended use can be provided. As part of the PMA application review, the FDA will inspect the manufacturer’s facilities for compliance with its Quality System Regulation, or QSR. As part of the PMA approval the FDA may place restrictions on the device, such as requiring additional patient follow-up for an indefinite period of time. If the FDA’s evaluation of the PMA application or the manufacturing facility is not favorable, the FDA may deny approval of the PMA application or issue a “not approvable” letter. The FDA may also require additional clinical trials, which can delay the PMA approval process by several years. After the PMA is approved, if changes are made to a device, its manufacturing or labeling, a PMA supplement containing additional information must be filed for prior FDA approval.

Historically, our products have been introduced into the market using the 510(k) procedure.

FDA submissions require extensive validations and testing which requires a significant amount of time and financial resources. Recent changes in both regulations and FDA perspectives have increased both time and testing requirements, which have caused and are expected to continue to cause significant delays and increased costs for clearances and approvals. The increased focus by the FDA on such issues as chemical identification of all colorants, non-acceptance of certain colorants (certain forms of carbon black) and other concerns, continue to cause challenges and delays. In addition, changes to existing products call into question previously approved devices and result in additional costs for testing and material analysis.

The devices manufactured by us are also subject to the QSR, which imposes elaborate testing, control, documentation and other quality assurance procedures on our manufacturing facilities. Every phase of production, including raw materials, components and subassembly, manufacturing, testing, quality control, labeling, tracing of customers after distribution and follow-up and reporting of complaint information is governed by the FDA’s QSR. Device manufacturers are required to register their facilities and list their products with the FDA and certain state agencies. The FDA periodically inspects manufacturing facilities and, if there are alleged violations, the operator of a facility must correct them or satisfactorily demonstrate the absence of the violations or face regulatory action. Failure to maintain compliance with the QSR may result in the issuance of one or more Forms 483 or warning letters and could potentially result in a consent decree. Failure to maintain the QSR appropriately could result in the issuance of further warning letters. In addition, non-compliance with applicable FDA requirements can result in, among other things, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, failure of the FDA to grant marketing approvals, inability to obtain clearances or approvals for products, withdrawal of marketing approvals, a recommendation by the FDA to disallow us to enter into government contracts, and/or criminal prosecutions. The FDA also has the authority to request repair, replacement or refund of the cost of any device manufactured or distributed by us.

Other U.S. Regulatory Bodies

We and our products are subject to a variety of federal, state and local laws in those jurisdictions where our products are, or will be, marketed. We and our products are also subject to a variety of federal, state and local laws relating to matters such as safe working conditions, manufacturing practices, environmental protection, fire hazard control and disposal of hazardous or potentially hazardous substances. In addition, we are subject to various federal and state laws governing our relationships with the physicians and others who purchase or make referrals for our products. For instance, federal law prohibits payments of any form that are intended to induce a referral for any item payable under Medicare, Medicaid or any other federal healthcare program. Many states have similar laws. There can be no assurance that we will not be required to incur significant costs to comply with such laws and regulations now or in the future, or that such laws or regulations will not have a material adverse effect upon our ability to do business.

International Regulation

Internationally, all of our current products are considered medical devices under applicable regulatory regimes, and we anticipate that this will be true for all of our future products. Sales of medical devices are subject to regulatory requirements in most countries. The regulatory review process varies greatly from country to country.

In order to distribute and sell products into the European Union as well as a number of other countries including many Central European Free Trade Agreement participants, Scandinavian, and Middle Eastern countries, a CE Mark is required. New products must be compliant with the Medical Device Regulation ("MDR") as of May 2021 and previously CE Marked products must become compliant when their certification expires, with a transition period ending December 2027 for higher classification devices, or December 2028 for lower classification devices. Products with an expiring certification must be in distribution before certification expiration dates to continue to be sold. Clinical evaluations of products under MDR requires more information than previously required. All devices must have current clinical literature that specifically addresses data-driven safety and performance criteria, and legacy devices often require additional biocompatibility, bench testing and redesign to address changes in standards over time. Additionally, there can be extended time frames under MDR for product certifications that can be 12-18 months or longer. During that time period, significant design modifications cannot be made. All legacy devices have achieved the MDR CE Mark.

Similar regulations are in place for Canada, Japan, China, Brazil and most other countries. In some cases, we rely on our international distributors to obtain regulatory approvals, complete product registrations, comply with clinical trial requirements and complete those steps that are customarily taken in the applicable jurisdictions.

International sales of medical devices manufactured in the United States that are not approved or cleared by the FDA for use in the United States, or are banned or deviate from lawful performance standards, are subject to FDA export requirements. Before exporting such products to a foreign country, we must first comply with the FDA’s regulatory procedures for exporting unapproved devices.

The process of obtaining approval to distribute medical products is costly and time-consuming in virtually all the major markets where we sell medical devices. We cannot assure that any new medical devices we develop will be cleared, approved

or certified in a timely or cost-effective manner or cleared, approved or certified at all. There can be no assurance that new laws or regulations regarding the release or sale of medical devices will not delay or prevent sale of our current or future products.

THIRD-PARTY REIMBURSEMENT AND ANTI-FRAUD AND CORRUPT PRACTICES REGULATION

United States

The delivery of our devices is subject to regulation by the Department of Health and Human Services (HHS) and comparable state and non-U.S. agencies responsible for reimbursement and regulation of health care items and services. U.S. laws and regulations are imposed primarily in conjunction with the Medicare and Medicaid programs, as well as the government’s interest in regulating the quality and cost of health care. Foreign governments also impose regulations in conjunction with their health care reimbursement programs and the delivery of health care items and services.

U.S. federal health care laws apply when we or customers submit claims for items or services that are reimbursed under Medicare, Medicaid, or other federally-funded health care programs. The principal U.S. federal laws include: (1) the Anti-kickback Statute which prohibits offers to pay or receive remuneration of any kind for the purpose of inducing or rewarding referrals of items or services reimbursable by a federal health care program, subject to certain safe harbor exceptions; (2) the False Claims Act which prohibits the submission of false or otherwise improper claims for payment to a federally-funded health care program, including claims resulting from a violation of the Anti-kickback Statute; (3) the Stark law which prohibits physicians from referring Medicare or Medicaid patients to a provider that bills these programs for the provision of certain designated health services if the physician (or a member of the physician’s immediate family) has a financial relationship with that provider; and (4) health care fraud statutes that prohibit false statements and improper claims to any third-party payer. There are often similar state false claims, anti-kickback, and anti-self-referral and insurance laws that apply to state-funded Medicaid and other health care programs and private third-party payers. In addition, the U.S. Foreign Corrupt Practices Act (FCPA) can be used to prosecute companies in the U.S. for arrangements with physicians or other parties outside the U.S. if the physician or party is a government official of another country and the arrangement violates the law of that country.

International

The delivery of our devices in any EU member country is subject to evolving regulation by the EU Medical Device Regulations, notified bodies and comparable nation-specific bodies whether part of the EU or not, responsible for reimbursement and regulation of health care items and services. Our success in international markets will depend largely upon the availability of reimbursement from the national public health payers as well as private, third party payors, through which healthcare providers are paid in those markets. Reimbursement and healthcare payment systems vary significantly by country. The main types of healthcare payment systems are government sponsored healthcare and private insurance. Reimbursement approval must be obtained individually in each country in which our products are marketed. Members of our healthcare economics team work directly with providers, our distributors and health systems to obtain reimbursement approval in the countries in which they will use or sell our products. There can be no assurance that reimbursement approvals will be received. See Part I. Item 1A "Risk Factors" in this Annual Report on Form 10-K.

INSURANCE

Our product liability insurance coverage is limited to a maximum of $10 million per product liability claim and an annual aggregate policy limit of $10 million, subject to a self-insured retention of $500,000 per occurrence and $2 million in the aggregate. The policy covers, subject to policy conditions and exclusions, claims of bodily injury and property damage from any product sold or manufactured by us.

There is no assurance that this level of coverage is adequate. We may not be able to sustain or maintain this level of coverage and cannot assure you that adequate insurance coverage will continue to be available on commercially reasonable terms, or at all. A successful product liability claim or other claim, with respect to uninsured or underinsured liabilities, could have a material adverse effect on our business. See Part I. Item 1A "Risk Factors" in this Annual Report on Form 10-K.

ENVIRONMENTAL, HEALTH AND SAFETY

We are subject to federal, state and local laws, rules, regulations and policies governing the use, generation, manufacture, storage, air emission, effluent discharge, handling and disposal of certain hazardous and potentially hazardous substances used in connection with our operations. Our operations are also subject to laws and regulations related to occupational health and safety. We maintain safety, training and maintenance programs as part of our ongoing efforts to ensure compliance with applicable laws and regulations. Although we believe that we have complied with environmental, health and safety laws and regulations in all material respects and, to date, have not been required to take any action to correct any noncompliance, there can be no assurance that we will not be required to incur significant costs to comply with environmental regulations in the future.

EMPLOYEES

As of May 31, 2025, we had approximately 675 full time employees. None of our employees are represented by a labor union and we have never experienced a work stoppage. In the highly competitive medical technology industry, we consider attracting, developing, engaging and retaining high performing talent in positions critical to our long-term growth strategy including but not limited to technical, operational, marketing, sales, research and development, and management. Our ability to recruit and retain such talent depends on several factors, including culture, compensation and benefits, talent development, career opportunities, recognition and work environment. Our goal is to create a diverse and inclusive culture that encourages an environment where employees feel welcomed, respected and valued. We are committed to making employment decisions without regard to race, religion, ethnicity or national origin, gender, sexual orientation, gender identity or expression, age, disability, protected veteran status or any other characteristics protected by law.

The engagement of our workforce is crucial to delivering on our competitive strategy, and we place high importance on informed and engaged employees. We communicate frequently and transparently with our employees through a variety of communication methods, including video and written communications, town hall meetings and our company intranet.

Item 1A. Risk Factors.

In addition to the other information contained in this Annual Report on Form 10-K and in our other filings with the Securities and Exchange Commission, the following risk factors should be considered carefully by investors in evaluating our business. Our financial and operating results are subject to a number of risks and uncertainties, including those set forth below, many of which are not within our control. Our business, financial condition, results of operations and/or liquidity could be materially and adversely affected by any of these risks or by additional risks not presently known to us or that we currently deem immaterial.

RISKS RELATED TO OUR BUSINESS AND INDUSTRY

We face intense competition in the medical device industry which continues to experience consolidation. We may be unable to compete effectively with respect to technological innovation and price which may have a material adverse effect on our revenues, financial condition, results of operations and/or liquidity.

The markets for our products are highly competitive and we expect competition to continue to intensify. The medical device industry is characterized by rapid technological change, frequent product introductions and evolving customer requirements. Our customers consider many factors when choosing products, including technology, features and benefits, quality, reliability, ease of use, clinical or economic outcomes, availability, price and customer service. We face competition globally from a wide range of companies, many of whom have substantially greater financial, marketing and other resources than us. We may not be able to compete effectively, and we may lose market share to our competitors.

Our competitors may succeed in adapting faster than us to changing customer needs or requirements, in developing and introducing technologies and products earlier, in obtaining patent protection (which could create barriers to market entry for us) or regulatory clearance earlier, or in commercializing new products or technologies more rapidly than us. Our competitors may also develop products and technologies that are superior to ours or that otherwise could render our products obsolete or noncompetitive. The trend of increased consolidation in the medical technology industry has resulted in companies with greater scale and market power, intensifying competition and increasing pricing pressure. We may also face competition from providers of other medical therapies, such as pharmaceutical companies, that may offer non-surgical therapies for conditions that are currently, or in the future may be, treated using our products. If we are not able to compete effectively, our market share and revenue may decline.

In addition, the increasing purchasing power of health systems, group purchasing organizations (“GPOs”) and integrated health delivery networks (“IDNs”), together with increased competition and declining reimbursement rates, has resulted increasingly with the Company competing on the basis of price. Due to the highly competitive nature of the GPO and IDN contracting processes, we may not be able to obtain market prices for our products or obtain or maintain contract positions with major GPOs and IDNs, which could adversely impact our profitability. Also, sales through a GPO or IDN can be significant to our business and our inability to retain contracts with our customers, or acquire additional contracts, could have a material adverse effect on our business, financial condition, results of operations and/or liquidity.

Our inability to continue to effectively develop, acquire and/or market new products and technologies could have a material adverse effect on our business, financial condition and/or results of operations.

The market for our devices is characterized by rapid technological change, new product introductions, technological improvements, changes in physician requirements and evolving industry standards. Product life cycles are relatively short because medical device manufacturers continually develop more effective and less expensive versions of existing devices in response to physician demand. We engage in product development and improvement programs to maintain and improve our competitive position. Our products are technologically complex and these programs involve significant planning, market studies, investment in research and development, clinical trials and regulatory clearances or approvals and may require more time and expense than anticipated to bring such products to market. We may not, however, be successful in enhancing existing products, or developing new products or technologies that will achieve regulatory approval, be developed or manufactured in a cost-effective manner, obtain appropriate intellectual property protection or receive market acceptance. We also may be unable to recover all or a meaningful part of our investment in these products or technologies. Additionally, there can be no assurance that the size of the markets in which we compete will increase above existing levels or not decline, that we will be able to maintain, gain or regain market share or that we can compete effectively on the basis of price or that the number of procedures in which our products are used will increase above existing levels or not decline.

In particular, the future prospects of many of our high growth products, such as the NanoKnife system, the AngioVac system, the AlphaVac system and the Auryon system, rely on continued market development and continued generation of clinical data pursuant to clinical trials conducted by us, our competitors or other third parties. If the results of these trials are not what we expect or fail to generate meaningful clinical data, it may adversely impact our ability to obtain product approvals. If

any of these products fail to achieve clinical acceptance or are perceived unfavorably by the market, it could severely limit our ability to drive revenue growth, which could have a material adverse effect on our business, financial condition, results of operations and/or liquidity.

As part of our business strategy, we expect to continue to engage in business development activities which includes selectively evaluating and pursuing the acquisition of complementary businesses, technologies and products. These activities may result in substantial investment of our time and financial resources and competition for targets may be significant. We may not be able to identify appropriate acquisition candidates, consummate transactions, obtain agreements with favorable terms or obtain any necessary financing or regulatory approvals. Further, once a business is acquired, any inability to successfully integrate the business or achieve anticipated cost savings or operating synergies, decreases in customer loyalty or product orders, failure to retain and develop its workforce, failure to establish and maintain appropriate controls, higher or unanticipated expenses, or unknown or contingent liabilities could adversely affect our ability to realize the anticipated benefits of any acquisition. The evaluation and integration of an acquired business, whether or not successful, requires significant efforts which may result in additional expenses and divert the attention of our management and technical personnel from other projects.

If we proceed with one or more significant acquisitions in which the consideration consists of cash, a substantial portion of our available cash could be used to consummate the acquisitions. If we consummate one or more acquisitions in which the consideration consists of capital stock, our stockholders could suffer significant dilution of their interest in us. In addition, we could incur or assume significant amounts of indebtedness in connection with acquisitions. These transactions are inherently risky and may not enhance our financial position or results of operations or create value for our shareholders as they are based on projections and assumptions which are uncertain and subject to change and there can be no assurance that any past or future transaction will be successful.

If we fail to develop and successfully manufacture and launch new products, generate satisfactory clinical results, provide sufficient economic value, enhance existing products, or identify, acquire and integrate complementary businesses, technologies and products or if we experience a decrease in market size or market share or declines in average selling price or procedural volumes, or otherwise fail to compete effectively, we may not achieve our growth goals, which could have a material adverse effect on our business, financial condition and/or results of operations.

If we do not maintain our reputation with interventional physicians, interventional and surgical oncologists, and critical care nurses, our growth will be limited and our business could be harmed.

Physicians typically influence the medical device purchasing decisions of the hospitals and other healthcare institutions in which they practice. Consequently, our reputation with interventional physicians, interventional and surgical oncologists, and critical care nurses is crucial to our continued growth. We believe that we have built a positive reputation based on the quality of our products, our physician-driven product development efforts, our marketing and training efforts and our presence at medical society meetings. Any actual or perceived diminution in the quality of our products, or our failure or inability to maintain these other efforts, could damage our reputation with interventional physicians, interventional and surgical oncologists, and critical care nurses, and cause our growth to be limited and our business to be harmed, which could have a material adverse effect on our business, financial condition, results of operations and/or liquidity.

Our business and prospects rely heavily upon our ability to successfully complete clinical trials, including, but not limited to, our Ambition BTK clinical study.We may choose to, or may be required to, suspend, repeat or terminate our clinical trials if they are not conducted in accordance with regulatory requirements, the results are negative or inconclusive or the trials are not well designed.

Clinical trials must be conducted in accordance with the applicable laws and regulations in the jurisdictions in which the clinical trials are conducted, including current Good Clinical Practices. The clinical trials are subject to oversight by the FDA, regulatory agencies in other jurisdictions, ethics committees and institutional review boards at the medical institutions where the clinical trials are conducted. Clinical trial protocols may require a large number of patients to be enrolled in the trials. Patient enrollment is a function of many factors, including the size of the patient population for the target indication, the proximity of patients to clinical sites, the eligibility criteria for the trial, the existence of competing clinical trials and the availability of alternative or new treatments. Clinical trials may be suspended by the FDA or by a regulatory agency in another jurisdiction at any time if the FDA or the regulatory agency finds deficiencies in the conduct of these trials or it is believed that these trials expose patients to unacceptable health risks.

We, the FDA or regulatory agencies in other jurisdictions might delay or terminate our clinical trials for various reasons, including insufficient patient enrollment, fatalities, unforeseen adverse side effects by enrolled patients or the development of new therapies that require us to revise or amend our clinical trial protocols. Patients may be discouraged from enrolling in our clinical trials if the trial protocol requires them to undergo extensive follow-up to assess safety and effectiveness, if they

determine that the treatments received under the trial protocols are not attractive or involve unacceptable risks or discomforts or if they participate in contemporaneous clinical trials of competing products.

In addition, we rely on contract research organizations, or CROs, with respect to conducting our clinical trials. We may experience significant cost overruns associated with, and we may encounter difficulties managing, these CROs. Termination of our clinical trials or significant delays in completing our clinical trials could have a material adverse effect on our business, financial condition, results of operations and/or liquidity.

We are dependent on single and limited source suppliers which subjects our business and results of operations to risks of supplier business interruptions.

We currently purchase significant amounts of several key products, raw materials and product components from single and limited source suppliers and anticipate that we will do so for future products as well. Any delays in delivery of or shortages in those or other products and components (like we experienced during our 2022 and 2023 fiscal year) could interrupt and delay manufacturing of our products, lead to backlogs and result in the cancellation of orders for our products. Any or all of these suppliers could discontinue the manufacture or supply of these products, raw materials and/or components at any time.

Due to FDA and other business considerations, we may not be able to identify and integrate alternative sources of supply in a timely fashion or at all. Any transition to alternate suppliers may result in production delays and increased costs and may limit our ability to deliver products to our customers. Furthermore, if we are unable to identify alternative sources of supply, we would have to modify our products to use substitute components, which may cause delays in shipments, backlogs, increased prices for our products or increased design and manufacturing costs.

In addition, we historically have purchased and may purchase in the future certain products as a distributor for the manufacturer of those products. Any constraint or interruption in the supply of raw materials, other product components or finished products that we distribute could materially impact our ability to sell products, and have a material adverse effect on our business, financial condition, results of operations and/or liquidity.

We rely on third-party manufacturers to manufacture some of our products today, and we have announced a plan to move to a partially outsourced model for manufacturing in various parts of the world, which exposes us to additional risks, including reduced control over manufacturing, delivery timing, product quality issues, potential price fluctuations, regulatory, environmental, labor or other operational disruptions, which would result in a loss of revenue or reduced profitability.

We currently rely on third-party manufacturers for a portion of our products. We also announced a plan to transfer certain product manufacturing processes from Queensbury, NY to third-party manufacturers located in various parts of the world, including, but not limited to the United States, Costa Rica, Latvia, Italy, Israel and China. The restructuring activities associated with this plan are expected to be completed in the third quarter of fiscal year 2026. If we are unable to effectively execute on this plan within the announced timeline it could have a material adverse effect on our business, financial condition and/or results of operations.

Our manufacturing strategy may present certain risks and uncertainties that could have a material adverse effect on our business, financial condition and/or results of operations, many of which we cannot predict, including, but not limited to:

•the ability to effectively negotiate and enter into contracts with third party manufacturers;

•if market demand for our products is less than our purchase obligations to our manufacturers, we may incur substantial penalties and substantial inventory write-offs;

•manufacturers of our products are subject to ongoing periodic inspections by the FDA and other regulatory authorities for compliance with strictly enforced good manufacturing practices regulations and similar foreign standards, and we do not have control over our third-party manufacturers’ compliance with these regulations and standards;

•we may have to share intellectual property rights, including any improvements in the manufacturing processes or new manufacturing processes for our products;

•our product costs may increase if our manufacturers pass their increasing costs onto us;

•if our agreement with a third-party manufacturer expires, we may not be able to renegotiate a new agreement with that manufacturer on favorable terms, if at all. If we cannot successfully complete such renegotiation, we may not be able to locate any necessary acceptable replacement manufacturers or enter into favorable agreements with such replacement manufacturers in a timely manner, if at all; and

•manufacturing could be curtailed or partially or completely shut down as the result of a number of circumstances, most of which are outside of our control, such as unscheduled maintenance, an earthquake, hurricane, flood, tsunami or other natural disaster, significant labor strikes or work stoppages, government implementation of export limitations or freezes, political unrest or pandemics.

In addition, our business practices in international markets are subject to the requirements of the U.S. Foreign Corrupt Practices Act of 1977, as amended, any violation of which could subject us to significant fines, criminal sanctions and other penalties. We expect all of our contracted manufacturing facilities, to comply with all applicable laws, including labor, safety and environmental laws, and to otherwise meet our standards of conduct. Our ability to find manufacturing facilities that uphold these standards is a challenge, especially with respect to facilities located outside the United States. We also are subject to the risk that one or more of these manufacturing facilities will engage in business practices in violation of our standards or applicable laws, which could damage our reputation, hurt our relationship with our customers and result in negative publicity, damage to our brand and a material and adverse effect on our business, financial condition, results of operations and/or liquidity.

Recent changes in trade policy, treaties, government regulations and tariffs have created significant uncertainty about the future relationship between the U.S. and various other countries where we have employees, customers, suppliers and operations. Changes in policy regarding international trade, including import and export regulation and international trade agreements, could negatively impact our business. The implementation of new tariffs on imports from Canada, Mexico, China or other countries for an extended period and without specific exemptions for our products, and any reciprocal tariffs or other reactions by other countries thereto, could have a material adverse impact on our financial condition, results of operations and cash flows.

A portion of our component sourcing, supply chain and manufacturing activities are conducted in or partially sourced from China. As a result, our business, financial condition, results of operations could be affected significantly by economic, political and legal developments in China as well as trade disputes between China and the United States and the potential imposition of bilateral tariffs. The imposition of tariffs or export restrictions on products imported by us from China could require us to (i) increase prices to our customers or (ii) locate suitable alternative manufacturing capacity or relocate our operations from China to other countries. In the event we are unable to increase our prices or find alternative manufacturing capacity or relocate to an alternative base of operation outside of China on favorable terms, we would likely experience higher manufacturing costs and lower gross margins, which could have an adverse effect on our business and results of operations. The Chinese economy differs from the economies of most developed countries in many respects, including the degree of government involvement, the level of development, the growth rate, the control of foreign exchange, access to financing and the allocation of resources.

We are heavily dependent on third-party distributors to generate a substantial portion of our international revenues and are at the risk of these distributors also selling for our competitors, failing to be financially viable and failing to effectively distribute our products in compliance with applicable laws.

Outside of North America we rely heavily on third party distributors, either on a country-by-country basis or on a multi-country, regional basis, to market, sell and distribute our products where we do not have a direct sales and marketing presence (including, among others, China, Japan, Brazil, the Middle East and many European countries). As such, our revenue, if any, depends on the terms of such arrangements and the distributors’ efforts. These efforts may turn out not to be sufficient and our third-party distributors may not effectively sell our products. International distributors accounted for approximately 74% of international revenues for the fiscal year ended May 31, 2025. International sales decreased 21% in fiscal year 2025 partially due to the sale of the PICCs, Midline, dialysis and BioSentry businesses, along with the discontinuation of the RadioFrequency Ablation product line. If we are unable to maintain our relationships or establish direct sales capabilities on acceptable terms or at all, we may lose significant revenue or be unable to achieve our growth aspirations. In certain circumstances, distributors may also sell competing products, or products for competing diagnostic modalities, and may have incentives to shift sales towards those competing products. As a result, we cannot assure you that our international distributors will increase or maintain our current levels of unit sales or increase or maintain our current unit pricing, which, in turn, could have a material adverse effect on our business, financial condition, results of operations and/or liquidity. In addition, there is a risk that our distributors will not be financially viable due to current economic and/or regulatory events in their respective countries or remit payments to us in a timely manner. If our distributors fail to comply with applicable laws or fail to effectively market and sell our products, our financial condition and results of operations could be materially and adversely impacted.

We face currency and other risks associated with international sales.

We generate revenue from international sales which could expose us to risks including fluctuations in currency values, trade restrictions, tariff and trade regulations, U.S. export controls, U.S. and non‐U.S. tax laws, shipping delays and economic and political instability, which could have a material adverse effect on our business, results of operations, financial conditions and cash flows.

If we are unable to convince customers that our products can improve the cost structure of their business, or to secure adequate reimbursement for our products our revenue growth and profitability may be materially and adversely impacted.

Our products are used in medical procedures and purchased principally by hospitals or physicians which typically bill various third-party payors, such as governmental programs (e.g., Medicare, Medicaid and comparable foreign programs), private insurance plans and managed care plans, for the healthcare services provided to their patients. Worldwide initiatives to contain healthcare costs have led governments and the private sector to enact cost containment efforts as a means of managing the growth of health care utilization. Common techniques include policies on price regulation, competitive pricing, bidding and tender mechanics, coverage and payment, comparative effectiveness of therapies, technology assessments, and managed-care arrangements. These changes are causing the marketplace to put increased emphasis on the delivery of more cost-effective medical devices and therapies. Government programs, including Medicare and Medicaid, private health care insurance, and managed-care plans have attempted to control costs by limiting the amount of reimbursement they will pay for particular procedures or treatments, tying reimbursement to outcomes, shifting to population health management, and other mechanisms designed to constrain utilization and contain costs. The ability of our customers to obtain appropriate reimbursement for products and services from third-party payors is critical to the success of medical device companies because it affects which products customers purchase and the prices they are willing to pay. In general, a third-party payor only covers a medical product or procedure when the plan administrator is satisfied that the product or procedure improves health outcomes, including quality of life or functional ability, in a safe and cost-effective manner. Even if a device has received clearance or approval for marketing by the FDA, there is no assurance that third-party payors, including Medicare and managed care companies, will cover the cost of the device and related procedures. Even if coverage is available, third-party payors may place restrictions on the circumstances where they provide coverage or may offer reimbursement that is not sufficient to cover the cost of our products. This has created an increasing level of price sensitivity among customers for our products and could have a material adverse effect on our business, financial condition, results of operations and/or liquidity.

Third-party payors who cover the cost of medical products or equipment, in addition to allowing a general charge for the procedure, often maintain lists of exclusive suppliers or approved lists of products deemed to be cost-effective. If our products are not on approved lists of third-party payors, healthcare providers must determine if the additional cost and effort required in obtaining prior authorization, and the uncertainty of actually obtaining coverage, is justified by any perceived clinical benefits from using our products.

Finally, the advent of contracted fixed rates per procedure has made it difficult to receive reimbursement for disposable products, even if the use of these products improves clinical outcomes. In addition, many third-party payors are moving to managed care systems in which providers contract to provide comprehensive healthcare for a fixed cost per person. Managed care providers often attempt to control the cost of healthcare by authorizing fewer elective surgical procedures. Under current prospective payment systems, such as the diagnosis related group system and the hospital out-patient prospective payment system, both of which are used by Medicare and in many managed care systems used by private third-party payors, the cost of our products will be incorporated into the overall cost of a procedure and not be separately reimbursed.

If hospitals and physicians cannot obtain adequate reimbursement for our products or the procedures in which they are used, this could have a material adverse effect on our business, financial condition, results of operations and/or liquidity.

Reimbursement varies by country and can significantly impact the acceptance of new technology. Implementation of healthcare reforms in the United States and in other countries may limit, reduce or eliminate reimbursement for our products and adversely affect both our pricing flexibility and the demand for our products. Even when we develop a promising new product, we may find limited demand for the product unless reimbursement approval is obtained from private and governmental third-party payors. Changes in healthcare systems in the United States or elsewhere in a manner that significantly reduces reimbursement for procedures using our medical devices or denies coverage for these procedures, or adverse decisions relating to our products by administrators of these systems in coverage or reimbursement issues, would have an adverse impact on the acceptance of our products and the prices which our customers are willing to pay for them.

Pending or future product liability claims brought against us, especially if our product liability insurance coverage is inadequate, could adversely impact our business, operations and financial results.

The design, manufacture and marketing of the types of medical devices we sell entail an inherent risk of product liability. Our products are used by physicians to treat seriously ill patients. We are periodically subject to product liability claims, and patients or customers may in the future bring claims against us in a number of circumstances and for a number of reasons, including if our products were misused, if a component of our product fails, if our manufacture or design was flawed, if the product produced unsatisfactory results or if the instructions for use and operating manuals and disclosure of product related risks for our products were found to be inadequate. For example, numerous product liability claims involving the Company's port products which were previously pending in various state and federal court jurisdictions have been consolidated, together with additional product liability claims, in a single multidistrict litigation in the U.S. District Court for the Southern District of California. We are unable to predict the outcome of these proceedings. See Part I, Item 3 "Legal Proceedings" in this Annual Report on Form 10-K for additional information on these proceedings.

In addition, individuals or groups seeking to represent a class may file suit against us in the future. Legal proceedings in general, class actions, multidistrict litigation, governmental investigations and actions in particular, can be expensive and disruptive, and adverse publicity could harm our reputation, regardless of validity of the allegations. The outcome of litigation, particularly class action and multidistrict litigation, is difficult to assess or quantify. Plaintiffs in these types of lawsuits often seek recovery of very large or indeterminate amounts, including not only actual damages, but also punitive damages. The magnitude of the potential losses relating to these lawsuits may remain unknown for substantial periods of time.

We carry a product liability policy with a limit of $10.0 million per product liability claim and an aggregate policy limit of $10.0 million, subject to a self-insured retention of $0.5 million per occurrence and $2.0 million in the aggregate. We believe, based on claims made against us in the past, our existing product liability insurance coverage is reasonably adequate to protect us from any liabilities we might incur. However, there is no assurance that this coverage will be sufficient to satisfy any claim made against us. In addition, we may not be able to continue to maintain adequate coverage at a reasonable cost and on reasonable terms, if at all. Any product liability claim brought against us, with or without merit, could increase our product liability insurance rates or prevent us from securing any coverage in the future. Additionally, if one or more product liability claims is brought against us for uninsured liabilities or is in excess of our insurance coverage, our financial condition, results of operations and/or liquidity could be negatively impacted. Further, such claims may require us to recall some of our products, which could result in significant costs to us.

We may be exposed to risks associated with product line divestitures as we may never realize the expected benefits and could cause operational disruptions with personnel, systems and infrastructure changes.

The Company's recent divestitures of its PICCs and Midline businesses to Spectrum Vascular and dialysis product portfolio and BioSentry tract sealant system biopsy business to Merit Medical Systems, Inc., along with potential future divestitures of certain product lines will allow us to transform ourselves into a high growth, highly profitable, medical technology company. If we are unable to achieve our growth and profitability objectives due to competition, lack of acceptance of our products, failure to generate favorable clinical data or gain regulatory approvals, or other risks as described in this section, or due to other events, we will not be successful in transforming our business and may not see the appropriate market valuation. The divestiture of product lines will impact revenue, earnings and cash flows, which over time we expect to replace by investing in higher margin revenue streams. There is a risk that we will be unable to replace the revenue, earnings and cash flow that these product lines generated, or that the cost of such will be higher than expected. If we are unable to achieve our profit and growth objectives, such failure will be exacerbated by the loss of revenue, earnings and cash flow generated by our divested product lines and could materially impact our financial position and results of operations, resulting in a decline in our stock price.

The sale of product lines could require us to restructure significant personnel, systems and infrastructure which may cause disruptions to our financial controls, IT, administrative support, manufacturing or regulatory processes and could have a material adverse effect on our business.

International and national economic and industry conditions constantly change, and could materially and adversely affect our business, financial condition and results of operations.

Our business, financial condition and results of operation are affected by many changing economic, industry and other conditions beyond our control. Actual or potential changes in international, national, regional and local economic, business and financial conditions, including recession, high inflation and trade protection measures, creditworthiness of our customers, fluctuations in currency values, U.S. export controls, U.S. and non-U.S. tax laws, shipping delays and economic and political instability, may negatively affect consumer preferences, perceptions, spending patterns or demographic trends, any of which could adversely affect our business, financial condition, results of operations and/or liquidity.

We are subject to macro-economic fluctuations in the U.S. and worldwide economy. Concerns about consumer and investor confidence, volatile corporate profits and reduced capital spending, international conflicts, terrorist and military activity, civil unrest and pandemic illness could reduce customer orders or cause customer order cancellations. In addition, political and social turmoil may put further pressure on economic conditions in the United States and abroad. The global economy has been periodically impacted by the effects of global economic downturns. There can be no assurance that there will not be further such events or deterioration in the global economy. These economic conditions make it more difficult for us to accurately forecast and plan our future business activities.

Volatility in the cost of raw materials, components, freight and energy increases the costs of producing and distributing our products. New laws or regulations adopted in response to climate change could also increase energy and transportation costs, as well as the costs of certain raw materials and components. Increases in oil prices may increase our packaging and transportation costs. Recently, the costs of labor, raw materials, transportation, construction, services, and energy necessary for the production and distribution of our products have increased significantly. While we have implemented cost containment

measures, selective price increases and taken other actions to offset these inflationary pressures in our supply chain, we may not be able to completely offset all the increases in our operational costs, any of which could adversely affect our business, financial condition, results of operations and/or liquidity.

Sales outside the U.S. accounted for approximately 14% of our net sales during our fiscal year ended May 31, 2025. We anticipate that sales from international operations will continue to represent a significant portion of our total sales, and we intend to continue our expansion into emerging and/or faster-growing markets outside the U.S. Our sales and profitability from our international operations are subject to risks and uncertainties that could have a material adverse effect on our business, financial condition and/or results of operations, many of which we cannot predict, including:

•fluctuations in currency exchange rates which may, in some instances affect spending behavior and reduce cash flows and revenue outside the U.S.;

•healthcare reform legislation;

•multiple non-U.S. regulatory requirements that are subject to change and could restrict our ability to manufacture and sell our products;

•local product preferences and product requirements;

•longer-term receivables than are typical in the U.S. and/or the ability to obtain payment;

•trade protection measures, tariffs and import or export licensing requirements;

•less intellectual property protection in some countries outside the U.S. than exists in the U.S.;

•different labor regulations and workforce instability;

•the potential payment of U.S. income taxes on earnings of certain foreign subsidiaries subject to U.S. taxation upon repatriation;

•the expiration and non-renewal of foreign tax rulings;

•potential negative consequences from changes in or interpretation of tax laws, including changes in our effective tax rate or the applicable tax rate in one or more jurisdictions; and

•economic instability and inflation, tariffs, recession or interest rate fluctuations.

Geopolitical developments related to various global conflicts are sources of uncertainty and may cause disruptions to global or regional markets, supply chains or operations in the regions. Russia’s invasion and military attacks on Ukraine have triggered significant sanctions from U.S. and European leaders. The Israel/Hamas war has also disrupted operations of companies doing business in the Middle East. These events may escalate and have created increasingly volatile global economic conditions. Resulting changes in U.S. trade policy could trigger retaliatory actions by Russia, its allies and other affected countries, including China and Israel, resulting in a “trade war.” A trade war could result in increased costs for raw materials we use in our manufacturing and could result in Russia, Israel and other foreign governments imposing tariffs on products that we export outside the U.S. or otherwise limiting our ability to sell our products abroad. These increased costs could have a material adverse effect on our business, financial condition and results of operations. Furthermore, if global conflicts continue for a long period of time, or if other countries, including the U.S., become further involved in the conflict, we could face material adverse effects on our business, financial condition, results of operations and/or liquidity.

Further, trade disputes or tensions may adversely affect our sales, including as a result of the imposition of tariffs or other barriers or restrictions on trade, or increase our costs. The institution of trade tariffs both globally and between the U.S. and China specifically could negatively impact the overall economic condition in our markets, including China, which could pose a significant risk to our business and would affect our revenue and cost of goods sold. The extent, focus and duration of any such tariffs and the resulting impact on general economic conditions and on our business are uncertain and depend on various factors, such as negotiations between the U.S. and affected countries, the responses of other countries or regions, exemptions or exclusions that may be granted, availability and cost of alternative sources of supply, and demand for our products in affected markets. Further, actions we take to adapt to new tariffs or trade restrictions may cause us to modify our operations or forgo business opportunities, which could have a material adverse impact on our business, financial condition, results of operations and/or liquidity.

Our business could be harmed if we cannot hire or retain qualified personnel.

Our business depends upon our ability to attract and retain highly qualified personnel, including managerial, sales, and technical personnel. We compete for key personnel with other companies, healthcare institutions, academic institutions, government entities and other organizations. We do not have written employment agreements with our executive officers, other than the CEO. Our ability to maintain and expand our business may be impaired if we are unable to retain our current key personnel or hire or retain other qualified personnel in the future, including personnel for our manufacturing facilities and field based sales employees. If we are not able to hire and retain personnel in our manufacturing facilities, we may not meet our production demand. In addition, our sales force is highly talented and we face intense competition in our industry for sales personnel which could have an adverse effect on our business and revenue if there is significant turnover.

If we are unable to manage our growth profitably, our business, financial results and stock price could suffer.

Our future financial results will depend in part on our ability to profitably manage our growth. Management will need to maintain existing customers and attract new customers, recruit, retain and effectively manage employees, as well as expand operations and integrate customer support and financial control systems. If integration-related expenses and capital expenditure requirements are greater than anticipated or if we are unable to manage our growth profitably, our financial results and the market price of our common stock may decline.

In recent years we have begun to implement operational excellence initiatives which include a number of restructuring, realignment and cost reduction initiatives. We may not realize the benefits of these initiatives to the extent or on the timing we anticipated and the ongoing difficulties in implementing these measures may be greater than anticipated and/or offset by inflationary pressures, which could cause us to incur additional costs or result in business disruptions like the backlog we experienced in fiscal year 2023. In addition, if these measures are not successful or sustainable, we may undertake additional realignment and cost reduction efforts, which could result in significant additional expenses and adversely impact our ability to achieve our other strategic goals and business plans.

We may fail to attract additional capital necessary to expand our business or may incur indebtedness which could impose operating and financial restrictions on us as a result of debt service obligations which could significantly limit our ability to execute our business strategy or curtail our growth.

We may require additional capital to expand our business. If cash generated internally is insufficient to fund capital requirements, we may require debt or equity financing. In addition, we may require financing to fund any significant acquisitions we may seek to make. Disruptions in the capital markets and increases in the cost of capital have previously resulted, and could again result, in volatility, decreased liquidity, and widening of credit spreads, which could make needed financing either unavailable or available on terms unsatisfactory to us which could result in significant stockholder dilution.

We may incur indebtedness or draw amounts on credit facilities in the future subject to limitations contained in the agreements governing our debt. The interest rate on potential borrowings could be a floating rate which could expose us to the risk of increased interest expense in the future. The terms of indebtedness could require us to comply with certain financial maintenance covenants. In addition, any future indebtedness could include, covenants restricting or limiting our ability to take certain actions. These covenants could adversely affect our ability to obtain additional financing, to finance future operations, to pursue certain business opportunities or take certain corporate actions. The covenants could also restrict our flexibility in planning for changes in our business and the industry and could make us more vulnerable to economic downturns and adverse developments, could limit our flexibility in planning for, or reacting to, changes and opportunities in the markets in which we compete, could place us at a competitive disadvantage compared to our competitors that have less debt or could require us to dedicate a substantial portion of our cash flow to service our debt.

Our ability to meet our cash requirements could be dependent upon our operating performance, which would be subject to general economic and competitive conditions and to financial, business and other factors affecting our operations, many of which could be beyond our control. We cannot provide assurance that our business operations would generate sufficient cash flows from operations to fund potential cash requirements and debt service obligations. If our operating results, cash flow or capital resources prove inadequate, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet other obligations. If we incurred indebtedness and were unable to service our debt, we could be forced to reduce or delay planned expansions and capital expenditures, sell assets, restructure or refinance our debt or seek additional equity capital, and we could be unable to take any of these actions on satisfactory terms or in a timely manner. Further, any of these actions may not be sufficient to allow us to service our potential debt obligations or could have an adverse impact on our business. Our potential debt agreements could limit our ability to take certain of these actions. Our failure to generate sufficient operating cash flow to pay our potential debts or to successfully undertake any of these actions could have a material adverse effect on us.

Inflationary pressure and unfavorable economic conditions could negatively affect our operations and business.

A significant deterioration in economic conditions, including economic slowdowns or recessions, increased unemployment levels, inflationary pressures or disruptions to credit and capital markets, could lead to decreased consumer confidence and spending and availability of credit. For example, a rapid increase in inflation levels may negatively impact demand for our products and increase our costs and may lead to a rapid increase in market interest rates. In addition, if rates increase, we may incur significant additional expense and adversely impact our ability to achieve our other strategic goals and business plans.

Our intangible assets and fixed assets are subject to potential impairment; we have historically recorded significant impairment charges and may be required to record additional charges to future earnings if our assets become impaired.

A significant portion of our assets consist of intangible assets and fixed assets, the carrying value of which may be reduced if we determine that those assets are impaired, including intangible assets from recent acquisitions.

Our intangible and fixed assets have finite useful lives and are amortized or depreciated over their useful lives on either a straight-line basis or over the expected period of benefit or as revenues are earned from the sales of the related products. The underlying assumptions regarding the estimated useful lives of these intangible assets are reviewed quarterly and more often if an event or circumstance occurs making it likely that the carrying value of the assets may not be recoverable and are adjusted through accelerated amortization if necessary. Whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable, we test intangible assets for impairment based on estimates of future cash flows. Factors that may be considered a change in circumstances indicating that the carrying value of our intangible assets may not be recoverable include a decline in stock price and market capitalization, slower growth rates in our industry or our own operations and/or other materially adverse events that have implications on the profitability of our business. When testing for impairment of definite-lived intangible assets held for use, the Company groups assets at the lowest level for which cash flows are separately identifiable. The Company operates as two reporting units and two asset groups. If a triggering event is deemed to exist, the Company performs an undiscounted operating cash flow analysis to determine if an impairment exists. If an intangible asset is considered to be impaired, the amount of the impairment will equal the excess of the carrying value over the fair value of the asset. If actual results differ from the assumptions and estimates used in the intangible asset calculations, we could incur future impairment or amortization charges, which could negatively impact our financial condition and results of operations.

We may be limited in our ability to utilize, or may not be able to utilize, net operating loss carryforwards to reduce our future tax liability.

IRC Section 382 and related provisions contain rules that limit for U.S. federal income tax purposes the ability of a Company that undergoes an “ownership change” to utilize its net operating loss carryforwards and certain other tax attributes existing as of the date of such ownership change. Our Federal net operating loss carryforwards as of May 31, 2025 after considering IRC Section 382 limitations are $135.6 million. The expiration of the Federal net operating loss carryforwards is as follows: $37.1 million between 2030 and 2032 and $98.5 million indefinitely. Our state net operating loss carryforwards as of May 31, 2025 after considering remaining IRC Section 382 limitations are $23.9 million which expire in various years from 2030 to 2043. Future ownership changes within the meaning of IRC Section 382 may also subject our tax loss carryforwards to annual limitations which would restrict our ability to use them to offset our taxable income in periods following the ownership changes. See Note 9, "Income Taxes" set forth in our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2025 for a further discussion of our tax loss carryovers.

A cyber-attack or other breach of our, our distributors, or our supply chain partners' information technology systems could have a material adverse effect on our business, financial condition and/or results of operations.

We rely on information technology systems to process, transmit, and store electronic information in our day-to-day operations. Similar to other large multi-national companies, the size and complexity of our information technology systems makes them vulnerable to cyber-attacks, malicious intrusions, breakdowns, destruction, losses of data privacy, or other significant disruptions. Our distributors and supply chain partners face similar risks. Our information systems require an ongoing commitment of resources to maintain, protect, and enhance existing systems and develop new systems to keep pace with continuing changes in information processing technology, evolving systems and regulatory standards, the increasing need to protect patient and customer information, and changing customer patterns. In addition, third parties may attempt to gain access into our systems or products or those of our supply chain partners to obtain data relating to patients or our proprietary information.

Any failure by us, our distributors, or our supply chain partners to maintain or protect information technology systems and data integrity, including from cyber-attacks, ransomware, intrusions or other breaches, could result in the unauthorized access to supply chain partners or vendors and personally identifiable information, theft of intellectual property, misappropriation of assets, or otherwise compromise confidential or proprietary information and disrupt operations of our Company, our distributors, or our supply chain partners. Any of these events, in turn, may cause us to lose existing customers, have difficulty preventing, detecting, and controlling fraud, have disputes with customers, our supply chain partners, physicians, and other health care professionals, be subject to legal claims and liability, have regulatory sanctions or penalties imposed, have increases in operating expenses, incur expenses or lose revenues as a result of a data privacy breach or theft of intellectual property, or suffer other adverse consequences, any of which could have a material adverse effect on our business, financial condition and/or results of operations.

Artificial intelligence based platforms present new risks and challenges to our business.

Artificial intelligence, or AI, based platforms are increasingly being used in the medical device and consumer health industries. We are committed to providing a safe and secure environment for all of our personnel, our business partners and our

customers, including the responsible use of AI chatbots and generative AI data processor products (“AI Systems”). We have developed policies governing the use of AI Systems to help reasonably ensure that such AI Systems are used in a trustworthy manner by our employees, contractors and authorized agents and that AngioDynamics’ assets, including intellectual property, competitive information, personal information and customer information, are protected. The failure by our personnel to adhere to the company’s established policies could violate confidentiality obligations or applicable laws and regulations, jeopardize our intellectual property rights, cause or contribute to unlawful discrimination or result in the misuse of personally identifiable information or the injection of malware into the company’s systems, any of which could have a material adverse effect on our business, results of operations and financial condition.

The use of AI Systems by our business partners with access to our confidential information, including trade secrets, may continue to increase and could lead to the release of such information, which could negatively impact our company, including our ability to realize the benefits of our intellectual property. The use of AI Systems by our business partners may lead to novel and urgent cybersecurity risks, which could have a material adverse effect on our operations and reputation as well as the operations of any of our business partners. We may also face increased competition from other companies that are using AI Systems, some of whom may develop more effective methods than we and any of our business partners have, which could have a material adverse effect on our business, results of operations and financial condition. In addition, uncertainties regarding developing legal and regulatory requirements and standards may require significant resources to modify and maintain business practices to comply with U.S. and non-U.S. laws concerning the use of AI and AI Systems, the nature of which cannot be determined at this time.

Any disaster at our manufacturing facilities or those of our suppliers could disrupt our ability to manufacture our products for a substantial amount of time.

We conduct manufacturing and assembly at facilities in Queensbury, New York, Glens Falls, New York, and other third parties in Costa Rica, Israel, Latvia, China and other locations. It would be difficult, expensive and time-consuming to transfer resources from one facility to the other and/or replace or repair these facilities or manufacturing equipment if they were significantly affected by a disaster. Additionally, we might be forced to rely on third-party manufacturers or delay production of our products. Insurance for damage to our properties and the disruption of our business from disasters may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, or at all. If one of our principal suppliers were to experience a similar disaster, uninsured loss or under-insured loss, we might not be able to obtain adequate alternative sources of supplies or products. Any significant uninsured loss, prolonged or repeated disruption, or inability to operate experienced by us or any of our principal suppliers could cause significant harm to our business, financial condition, results of operations and/or liquidity.

Anti-takeover provisions in our organizational documents and Delaware law may discourage or prevent a change of control, even if an acquisition would be beneficial to our stockholders, which could cause our stock price to decline and prevent attempts by our stockholders to replace or remove our current management.

Our amended and restated certificate of incorporation and our amended and restated bylaws contain provisions that may enable our management to resist a change in control. For example, our Board of Directors is classified so that not all members of our Board of Directors are elected at one time and our Board of Directors is authorized, without prior stockholder approval, to create and issue “blank check” preferred stock with rights senior to those of our common stock and stockholder action by written consent is prohibited. We are also subject to the provisions of Section 203 of the Delaware General Corporation Law, which may prohibit certain business combinations with stockholders owning 15% or more of our outstanding voting stock. These provisions may discourage, delay or prevent a change in the ownership of our Company or a change in our management. In addition, these provisions could limit the price that investors would be willing to pay in the future for shares of our common stock. Any delay or prevention of a change of control transaction or changes in our Board of Directors could cause the market price of our common stock to decline.

Global health crises, pandemics, epidemics or other outbreaks could adversely impact our business, operations and financial results.

We are subject to risks associated with global health crises, pandemics, epidemics or other outbreaks beyond our control which could adversely affect our business, operations and financial results. Such risks may also have the effect of heightening other risks described herein, such as those relating to general economic conditions, demand for our products, relationships with suppliers and sales efforts. For example, impacts from the COVID-19 pandemic and measures taken in response thereto, such as constraints in the capacities of hospitals and other healthcare providers to perform non-COVID related procedures, changes to our on-site operations, delays in product development efforts and related clinical trials and regulatory clearances and approvals, and disruptions to global supply chains and labor markets, resulting in cost inflation and raw material supply constraints, adversely affected our business and there can be no assurance that similar events will not occur in the future.

We could be negatively impacted by Environmental, Social and Governance (ESG), climate change and other sustainability-related matters.

Governments, investors, customers, employees and other stakeholders are increasingly focusing on corporate ESG practices and disclosures, including risks associated with climate change and expectations in this area are rapidly evolving. Shifts in weather patterns caused by climate change are expected to increase the frequency and severity of adverse weather conditions such as hurricanes, tornadoes, earthquakes, wildfires, droughts, extreme temperatures or flooding, which could cause or contribute to reduced workforce availability, increased production and distribution costs and disruptions and delays in our logistics and supply chain/operations as well as the operations of our customers. The increasing attention to corporate ESG initiatives and ESG risks could result in reduced demand for products, reduced profits and increased investigations and litigation. If we are unable to satisfy any new criteria by which our ESG practices may be assessed, investors may conclude that our policies and/or actions with respect to ESG matters and risks are inadequate. If we fail or are perceived to have failed to accurately disclose our progress on such initiatives or goals, our reputation, business, financial condition and results of operations could be adversely impacted.

RISKS RELATED TO THE REGULATORY ENVIRONMENT

We are subject to a comprehensive system of federal, state and international laws and regulations, and we could be the subject of investigations, enforcement actions or face lawsuits and monetary or equitable judgments.

We operate in many parts of the world, and our operations are affected by complex state, federal and international laws relating to healthcare, environmental protection, antitrust, anti-corruption, anti-bribery, fraud and abuse, export control, tax, employment and laws regarding privacy, personally identifiable information and protected health information, including, for example, the Food, Drug and Cosmetic Act (“FDCA”), various FDA and international regulations relating to, among other things, the development, quality assurance, manufacturing, importation, distribution, marketing and sale of, and billing for, our products, the federal Anti-Kickback Statute and Federal False Claims Act (Note 17), the U.S. Foreign Corrupt Practices Act (“FCPA”) and similar anti-bribery laws in international jurisdictions, including the UK Anti-Bribery Act, the federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), General Data Protection Regulation (“GDPR”), domestic and foreign data protection, data security and privacy laws, laws related to the collection, storage, use and disclosure of personal data and laws and regulations relating to sanctions and money laundering.

The failure to comply with these laws and regulatory standards, allegations of such non-compliance or the discovery of previously unknown problems with a product or manufacturer: (i) could result in FDA Form-483 notices and/or warning letters or the foreign equivalent, fines, delays or suspensions of regulatory clearances, investigations, detainment, seizures or recalls of products (with the attendant expenses), the banning of a particular device, an order to replace or refund the cost of any device previously manufactured or distributed, operating restrictions and/or civil or criminal prosecution, and/or penalties, as well as decreased sales as a result of negative publicity and product liability claims; (ii) could expose us to breach of contract claims, fines and penalties, costs for remediation and harm to our reputation; (iii) could result in criminal or civil sanctions, including substantial fines, imprisonment and exclusion from participation in healthcare programs such as Medicare and Medicaid and health programs outside the United States; and (iv) could otherwise disrupt our business and could have a material adverse effect on our business, financial condition, results of operations and/or liquidity.

The healthcare industry is under continued scrutiny from state, federal and international governments, including with respect to industry practices in the area of sales and marketing. Certain states, including Massachusetts, have recently passed or are considering legislation restricting our interactions with health care providers and requiring disclosure of many payments to them. The federal government has recently introduced similar legislation, which may or may not preempt state laws. If our marketing, sales or other activities fail to comply with the FDA’s or other comparable foreign regulatory agencies’ regulations or guidelines, or other applicable laws, we may be subject to warnings from the FDA or investigations or enforcement actions from the FDA, Medicare, the Office of Inspector General of the U.S. Department of Health and Human Services or other government agencies or enforcement bodies. We anticipate that the government will continue to scrutinize our industry closely, and that additional regulation by governmental authorities may increase compliance costs, increase exposure to litigation and may have other adverse effects to our operations. The Company’s failure to comply with any marketing or sales regulations or any other applicable regulatory requirements could adversely affect our business, results of operations, financial condition and/or liquidity.

In addition, lawsuits by or otherwise involving employees, customers, licensors, licensees, suppliers, vendors, business partners, distributors, shareholders or competitors with respect to how we conduct our business could be very costly and could substantially disrupt our business. The occurrence of an adverse monetary or equitable judgment or a large expenditure in connection with a settlement of any of these matters could have a material adverse effect on our business, financial condition, results of operations and/or liquidity.

If we or some of our suppliers fail to comply with the FDA’s Quality System Regulation, or QSR, and other applicable post-market requirements, our manufacturing operations could be disrupted, our product sales and profitability could suffer, and we may be subject to a wide variety of FDA enforcement actions.

Our manufacturing processes and those of some of our suppliers must comply with the FDA’s Quality System Regulation, or QSR, which governs the methods used in, and the facilities and controls used for, the design, testing, manufacture, control, quality assurance, installation, servicing, labeling, packaging, storage and shipping of medical devices, and with current medical device adverse event reporting regulations, and similar foreign rules and regulations. The FDA enforces the QSR through unannounced inspections. Despite our training and compliance programs, our internal control policies and procedures may not always protect us from negligent, reckless or criminal acts committed by our employees or agents. If we, or one of our suppliers, fail a QSR inspection, or if a corrective action plan adopted by us or one of our suppliers is not sufficient, the FDA may bring an enforcement action, and our operations could be disrupted and our manufacturing delayed. We are also subject to the FDA’s general prohibition against promoting our products for unapproved or “off-label” uses, the FDA’s adverse event reporting requirements and the FDA’s reporting requirements for field correction or product removals. The FDA has recently placed increased emphasis on its scrutiny of compliance with the QSR and these other post-market requirements. In addition, most other countries require us and our suppliers to comply with manufacturing and quality assurance standards for medical devices that are similar to those in force in the United States before marketing and selling our products in those countries. If we, or our suppliers, should fail to do so, we would lose our ability to market and sell our products in those countries.

If we cannot obtain and maintain marketing clearance or approval from governmental agencies, we will not be able to sell our products.

Our products are medical devices that are subject to extensive regulation in the United States and in the foreign countries in which they are sold. Unless an exemption applies, each medical device that we wish to market in the United States must receive either 510(k) clearance or Pre-Market Approval (“PMA”) from the FDA before the product can be sold. Either process can be lengthy and expensive. The FDA’s 510(k) clearance procedure, also known as “premarket notification,” is the process we have used for our current products. This process usually takes from four to twelve months from the date the premarket notification is submitted to the FDA, but may take significantly longer. Even after a device receives regulatory approval it remains subject to significant regulatory and quality requirements, such as manufacturing, recordkeeping, renewal, recertification or reporting and other post market approval requirements, which may include clinical, laboratory or other studies.

Product approvals by the FDA and other foreign regulators can be withdrawn due to failure to comply with regulatory standards or the occurrence of unforeseen problems following initial approval or may be re-classified to a higher regulatory classification, such as requiring a PMA for a previously cleared 510(k) device. The PMA process is much more costly, lengthy and uncertain. It generally takes from one to three years from the date the application is submitted to, and filed with the FDA, and may take even longer. In addition, any modification to an FDA-cleared medical device that could significantly affect its safety or effectiveness, or that would constitute a major change or modification in its intended use, requires a new FDA 510(k) clearance or, possibly, a PMA.

Regulatory regimes in other countries similarly require approval or clearance prior to our marketing or selling products in those countries. We rely on our distributors to obtain regulatory clearances or approvals of our products outside of the United States. If we are unable to obtain additional clearances or approvals needed to market existing or new products in the United States or elsewhere or obtain these clearances or approvals in a timely fashion or at all, or if our existing clearances are revoked, our revenues and profitability may decline.

We have obtained Medical Device Regulation ("MDR") approvals for our principal products sold in the European Union ("EU") ahead of expiration dates. Maintaining MDR approval requires annual random sampling of CE marked products including ensuring new and updated test standards are achieved, post-market clinical data is collected and product performance expectations are achieved as demonstrated through post-market surveillance. For multiple reasons, including but not limited to changing business strategies, labor shortages and contract resources, administrative delays, increased costs of obtaining MDR certification and availability of necessary data, certain products will not continue to be CE marked under MDR. The additional time and resources required to obtain MDR certification was a significant factor in, and the diligence required to maintain the CE mark under MDR will likely continue to influence, our decisions whether to discontinue sales and distribution of certain products in the EU.

Complying with and obtaining regulatory approval in foreign countries, including our efforts to comply with the requirements of the MDR, have and will likely continue to lead to additional uncertainty, risk, expense and delay in commercializing products in certain foreign jurisdictions, which could have a material adverse effect on our business, financial condition and/or results of operations.

Our products may be subject to product recalls, which may harm our reputation and divert managerial and financial resources.

The FDA and similar governmental authorities in other countries have the authority to order mandatory recall of our products or order their removal from the market if there are material deficiencies or defects in design, manufacture, installation, servicing or labeling of the product, or if the governmental entity finds that our products would cause serious adverse health consequences. A government mandated recall, voluntary recall or field action by us could occur as a result of component failures, manufacturing errors or design defects, including labeling defects. Any recall of our products may harm our reputation with customers and divert managerial, engineering and financial resources. There is no assurance that we will not incur warranty or repair costs, be subject to liability claims for damages related to product defects, or experience manufacturing, shipping or other delays or interruptions as a result of these defects in the future. Our insurance policies may not provide sufficient protection should a claim be asserted. A recall of any of our products could harm our reputation, divert managerial and financial resources and have a material adverse effect on our business, financial condition, results of operations and/or liquidity.

We may be subject to fines, penalties, injunctions or costly investigations if we are determined to be promoting the use of our products for unapproved or “off-label” uses.

Medical devices are cleared or approved for one or more specific intended uses and promoting a device for an off-label use could result in government enforcement action. If the FDA determines that our promotional materials, sales techniques, pricing programs or training constitutes promotion of an off-label use or encourages over-utilization of our products or use of our products in combinations that are not indicated or appropriate, the FDA could request that we modify materials, techniques, programs or training or subject us to enforcement actions, including the issuance of a warning letter, injunction, seizure, civil fine and criminal penalties. It is also possible that other federal, state or foreign enforcement authorities, including the U.S. Department of Justice ("DOJ"), might take similar actions, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. Any of these results could have a material adverse effect on our business, financial condition, results of operations and/or liquidity.

Laws and regulations governing the export of our products could adversely impact our business. If the U.S. government imposes strict sanctions on certain countries, our revenue could be impacted.

The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC), and the Bureau of Industry and Security at the U.S. Department of Commerce (BIS), administer certain laws and regulations that restrict U.S. persons and, in some instances, non-U.S. persons, in conducting activities, transacting business with or making investments in certain countries, governments, entities and individuals subject to U.S. economic sanctions.

Due to our international operations, we are subject to such laws and regulations, which are complex, restrict our business dealings with certain countries and individuals, and are constantly changing. Further restrictions may be enacted, amended, enforced or interpreted in a manner that materially impacts our operations.

In fiscal year 2025 we generated $0.6 million of revenue for sales to distributors doing business in Iran. We continuously review our ability to sell products to distributors that conduct business in Iran in accordance with all applicable U.S. laws.

We have limited business dealings in certain other countries that are or may become subject to comprehensive sanctions. These business dealings may expose us to a heightened risk of violating applicable sanctions regulations. Violations of these regulations are punishable by civil penalties, including fines, denial of export privileges, injunctions, asset seizures, debarment from government contracts, revocations or restrictions of licenses, and/or criminal fines and imprisonment. We have established policies and procedures designed to assist with our compliance with such laws and regulations. However, there can be no assurance that our policies and procedures will effectively prevent us from violating these regulations in every transaction in which we may engage, and such a violation could adversely affect our reputation, business, financial condition, results of operations and cash flows.

RISKS RELATED TO INTELLECTUAL PROPERTY

If we fail to adequately protect our intellectual property rights, we may not be able to generate revenues from new or existing products and our business may suffer.

Our success depends in part on obtaining, maintaining and enforcing our patents, trademarks and other proprietary rights, and our ability to avoid infringing the proprietary rights of others. We rely upon patent, trade secret, copyright, know-how and trademark laws, as well as license agreements and contractual provisions, to establish our intellectual property rights and protect our products. However, no assurances can be made that any pending or future patent applications will result in the issuance of

patents, that any current or future patents issued to, or licensed by us, will not be challenged or circumvented by our competitors, or that our patents will not be found invalid.

Patent positions of medical device companies, including our Company, are uncertain and involve complex and evolving legal and factual questions. The coverage sought in a patent application can be denied or significantly reduced either before or after the patent is issued. Consequently, there can be no assurance that any of our pending patent applications will result in an issued patent. There is also no assurance that any existing or future patent will provide significant protection or commercial advantage, or whether any existing or future patent will be circumvented by a more basic patent, thus requiring us to obtain a license to produce and sell the product.

Additionally, we rely on trade secret protection for certain unpatented aspects of our proprietary technology. There can be no assurance that others will not independently develop or otherwise acquire substantially equivalent proprietary information or techniques, that others will not gain access to our proprietary technology or disclose such technology, or that we can meaningfully protect our trade secrets. We have a policy of requiring key employees and consultants to execute confidentiality agreements upon the commencement of an employment or consulting relationship with us. Our confidentiality agreements also require our employees to assign to us all rights to any inventions made or conceived during their employment with us. We also generally require our consultants to assign to us any inventions made during the course of their engagement by us. There can be no assurance, however, that these agreements will provide meaningful protection or adequate remedies for us in the event of unauthorized use, transfer or disclosure of confidential information or inventions. If we are not able to adequately protect our intellectual property, our market share, financial condition and results of operations may suffer.

If third parties claim that our products infringe their intellectual property rights, we may be forced to expend significant financial resources and management time defending against such actions and our financial condition and our results of operations could suffer.

Third parties may claim that our products infringe their patents and other intellectual property rights. Identifying third-party patent rights can be particularly difficult because, in general, patent applications can be maintained in secrecy for at least 18 months after their earliest priority date, and publication of discoveries in the scientific or patent literature often lag behind actual discoveries. Some companies in the medical device industry have used intellectual property infringement litigation to gain a competitive advantage. If a competitor were to challenge our patents, licenses or other intellectual property rights, or assert that our products infringe its patent or other intellectual property rights, we could incur substantial litigation costs, be forced to make expensive changes to our product design, pay royalties or other fees to license rights in order to continue manufacturing and selling our products, or pay substantial damages. Third-party infringement claims, regardless of their outcome, would not only consume our financial resources but also divert our management’s time and effort.

Such claims could also cause our customers or potential customers to purchase competitors’ products or defer or limit their purchase or use of our affected products until resolution of the claim. See Part I, Item 3 "Legal Proceedings" of this report for additional details on litigation regarding proprietary technology.

RISKS RELATED TO OUR STOCK PRICE

Our future operating results are difficult to predict and may vary significantly from quarter to quarter, which may adversely affect the price of our common stock.

The ongoing introduction of new products and services that affect our overall product mix make the prediction of future operating results difficult. You should not rely on our past results as any indication of future operating results. The price of our common stock will likely fall in the event that our operating results do not meet the expectations of analysts and investors. Comparisons of our quarterly operating results are an unreliable indication of our future performance because they are likely to vary significantly based on many factors, including:

•the level of sales of our products and services in our markets;

•our ability to introduce new products or services and enhancements in a timely manner;

•the demand for and acceptance of our products and services;

•the success of our competition and the introduction of alternative products or services;

•our ability to command favorable pricing for our products and services;

•the growth of the market for our devices and services;

•the expansion and rate of success of our direct sales force in the United States and internationally and our independent distributors internationally;

•actions relating to ongoing FDA compliance;

•our ability to integrate acquired assets or companies;

•the effect of intellectual property disputes;

•the size and timing of orders from independent distributors or customers;

•the attraction and retention of key personnel, particularly in sales and marketing, regulatory, manufacturing and research and development;

•unanticipated delays or an inability to control costs;

•general economic conditions, including inflationary pressure, as well as those specific to our customers and markets; and

•seasonal fluctuations in revenue due to the elective nature of some procedures.

Our stock price may be volatile, which may cause the value of our stock to decline or subject us to a securities class action litigation.

The trading price of our common stock price may be volatile and could be subject to wide fluctuations in price in response to various factors, many of which are beyond our control, attributable to outside factors and/or unrelated to operating performance. Such factors may include comments by securities analysts or other third parties, including blogs, articles, message boards and social and other media coverage which may not be attributable to us and may not be reliable or accurate.

The NASDAQ Stock Market and medical devices companies in particular have experienced substantial price and volume volatility that is often seemingly unrelated to the operating performance of the companies. These broad market fluctuations may cause the trading price of our common stock to decline. In the past, securities class action litigation has often been brought against a company after a period of volatility in the market price of its common stock.
