NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. CONSOLIDATED FINANCIAL STATEMENTS

The Consolidated Statements of Operations and the Consolidated Statements of Comprehensive Loss for the three and six months ended November 30, 2021 and 2020, the Consolidated Balance Sheet as of November 30, 2021, the Consolidated Statements of Cash Flows for the six months ended November 30, 2021 and 2020, and the Consolidated Statements of Stockholders’ Equity for the six months ended November 30, 2021 and 2020 have been prepared by the Company and are unaudited. The Consolidated Balance Sheet as of May 31, 2021 was derived from audited consolidated financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary to state fairly the financial position, changes in stockholders’ equity and comprehensive income, results of operations and cash flows as of and for the period ended November 30, 2021 (and for all periods presented) have been made.

The unaudited interim consolidated financial statements for the three and six months ended November 30, 2021 and 2020 include the accounts of AngioDynamics, Inc. and its wholly owned subsidiaries, collectively, "us", "we" or the “Company”. All intercompany balances and transactions have been eliminated.

2. ACQUISITIONS

Camaro Support Catheter Asset Acquisition

On July 27, 2021, the Company acquired the Camaro support catheter (rebranded as Syntrax) from QX Medical, LLC for an aggregate purchase price of $4.0 million, which included an upfront payment of $3.6 million and $0.4 million in purchase price holdbacks, along with $1.0 million of potential future contingent consideration related to revenue milestones. This acquisition supports the Auryon product family and the Company's strategic plan. The Company accounted for this acquisition as an asset purchase. The Company recorded the amount paid at closing as inventory and fixed assets of $0.1 million and an intangible asset product technology of $3.9 million. The intangible asset will be amortized over 15 years. The contingent consideration is comprised of revenue milestones and will be accounted for when the contingency is resolved or becomes probable and reasonably estimable.

3. REVENUE FROM CONTRACTS WITH CUSTOMERS

Revenue Recognition

Under ASC 606, Revenue from Contracts with Customers, revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

The Company has one primary revenue stream which is the sales of its products.

Disaggregation of Revenue

The following table summarizes net sales by Global Business Unit ("GBU") and geography:

As the Company has previously announced, the Company is focused on its ongoing transformation from a company with a broad portfolio of largely undifferentiated products to a more focused medical technology company that delivers unique and innovative health care solutions. The Company believes that this transformation will enable the Company to shift the portfolio from the mature, lower-growth markets where we have competed in the past by investing in technology and products that provide access to larger and faster growing markets. As such, we believe the growth in the near to mid-term will be driven by our high technology products including Auryon, Thrombectomy (which includes AngioVac, AlphaVac and thrombolytics) and NanoKnife. We will refer to these high technology products as our Med Tech business and we will refer to the remainder of the portfolio as our Med Device business.

The following table summarizes net sales by Med Tech and Med Device:

	Three Months Ended				Six Months Ended
(in thousands)	Nov 30, 2021		Nov 30, 2020		Nov 30, 2021		Nov 30, 2020
Net Sales

Total	$	78,280	$	72,770	$	155,251	$	142,986

Net Product Revenue

The Company's products consist of a wide range of medical, surgical and diagnostic devices used by professional healthcare providers for vascular access, for the treatment of peripheral vascular disease and for use in oncology and surgical settings. The Company's devices are generally used in minimally invasive, image-guided procedures. Most of the Company's products are intended to be used once and then discarded, or they may be implanted for short or long term use. The Company sells its products to its distributors and to end users, such as interventional radiologists, interventional cardiologists, vascular surgeons, urologists, interventional and surgical oncologists and critical care nurses.

Contracts and Performance Obligations

The Company contracts with its customers based on customer purchase orders, which in many cases are governed by master purchasing agreements. The Company’s contracts with customers are generally for product only, and do not include other performance obligations such as services or other material rights. As part of its assessment of each contract, the Company evaluates certain factors including the customer’s ability to pay (or credit risk). For each contract, the Company considers the promise to transfer products, each of which is distinct, to be the identified performance obligations.

Transaction Price and Allocation to Performance Obligations

Transaction prices of products are typically based on contracted rates. Product revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products to a customer, net of any variable consideration as described below.

If a contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products underlying each performance obligation. The Company has standard pricing for its products and determines standalone selling prices based on the price at which the performance obligation is sold separately.

10

Revenue Recognition

Revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied), which occurs at a point in time, and may be upon shipment from the Company’s manufacturing site or delivery to the customer’s named location, based on the contractual shipping terms of a contract.

In determining whether control has transferred, the Company considers if there is a present right to payment from the customer and when physical possession, legal title and risks and rewards of ownership have transferred to the customer.

The Company typically invoices customers upon satisfaction of identified performance obligations. As the Company’s standard payment terms are 30 to 90 days from invoicing, the Company does not provide any significant financing to its customers.

The Company enters into agreements to place placement and evaluation units (“units”) at customer sites, but the Company retains title to the units. During the duration of these agreements the customer has the right to use the unit at no upfront charge in connection with the customer’s ongoing purchase of disposables. These types of agreements include an embedded operating lease for the right to use the units. In these arrangements, revenue recognized for the sale of the disposables is not allocated between the disposal revenue and lease revenue due to the insignificant value of the units in relation to the total agreement value.

Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

Variable Consideration

Reserves: Revenue from product sales are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established for discounts, returns, rebates and allowances that are offered within contracts between the Company and its customers. These reserves are based on the amounts earned or to be claimed on the related sales and are classified as a contra asset.

Rebates and Allowances: The Company provides certain customers with rebates and allowances that are explicitly stated in the Company’s contracts and are recorded as a reduction of revenue in the period the related product revenue is recognized. The Company establishes reserves for such amounts, which is included in accrued expenses in the accompanying Consolidated Balance Sheets. These rebates and allowances result from performance-based offers that are primarily based on attaining contractually specified sales volumes. The Company is also required to pay administrative fees to group purchasing organizations.

Product Returns: The Company generally offers customers a limited right of return. Product returns after 30 days must be pre-approved by the Company and customers may be subject to a 20% restocking charge. To be accepted, a returned product must be unadulterated, undamaged and have at least twelve months remaining prior to its expiration date. The Company estimates the amount of its product sales that may be returned by its customers and records this estimate as a reduction of revenue in the period the related product revenue is recognized. The Company currently estimates product return liabilities using its historical product return information and considers other factors that it believes could significantly impact its expected returns, including product recalls. During the six months ended November 30, 2021, such product returns were not material.

Contract Balances with Customers

A receivable is generally recognized in the period the Company ships the product. Payment terms on invoiced amounts are based on contractual terms with each customer and generally coincide with revenue recognition. Accordingly, the Company does not have any contract assets associated with the future right to invoice its customers. In some cases, if control of the product has not yet transferred to the customer or the timing of the payments made by the customer precedes the Company’s fulfillment of the performance obligation, the Company recognizes a contract liability that is included in deferred revenue in the accompanying Consolidated Balance Sheets.

The following table presents changes in the Company’s receivables, contract assets and contract liabilities with customers:

(in thousands)	Nov 30, 2021		May 31, 2021
Receivables	$	38,205	$	35,405
Contract assets	$	—	$	—
Contract liabilities	$	690	$	426

During the six months ended November 30, 2021, the Company had additions to contract liabilities of $0.8 million. This was offset by $0.5 million in revenue that was recognized during the six months ended November 30, 2021.

Costs to Obtain or Fulfill a Customer Contract

Under ASC 606, the Company may recognize an asset for incremental costs of obtaining a contract with a customer if it expects to recover those costs. The Company’s sales incentive compensation plans qualify for capitalization since these plans are directly related to sales achieved during a period of time. However, the Company has elected the practical expedient under ASC 340-40-25-4 to expense the costs as they are incurred within selling and marketing expenses since the amortization period is less than one year.

The Company accounts for shipping and handling activities related to contracts with customers as costs to fulfill the promise to transfer the associated products. Shipping and handling costs, associated with the distribution of finished products to customers, are recorded in costs of goods sold and are recognized when the related finished product is shipped to the customer. Amounts charged to customers for shipping and handling are recorded in net sales.

4. INVENTORIES

Inventories are stated at lower of cost and net realizable value (using the first-in, first-out method). Inventories consisted of the following:

(in thousands)	Nov 30, 2021		May 31, 2021
Raw materials	$	26,706	$	22,925
Work in process	6,673		8,022
Finished goods	14,804		17,667
Inventories	$	48,183	$	48,614

The Company periodically reviews inventory for both obsolescence and loss of value. The Company makes assumptions about the future demand for and market value of the inventory. Based on these assumptions, the Company estimates the amount of obsolete, expiring and slow-moving inventory. The total inventory reserve at November 30, 2021 and May 31, 2021 was $4.0 million and $3.8 million, respectively.

5. GOODWILL AND INTANGIBLE ASSETS

Goodwill

Goodwill is not amortized, but rather, is tested for impairment annually or more frequently if impairment indicators arise. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in each business combination.

The Company's annual testing for impairment of goodwill was completed as of December 31, 2020. The Company operates as a single operating segment with one reporting unit and consequently evaluates goodwill for impairment based on an evaluation of the fair value of the Company as a whole. The Company determines the fair value of the reporting unit based on the market valuation approach and concluded that it was not more-likely-than-not that the fair value of the Company's reporting unit was less than its carrying value.

Even though the Company determined that there was no goodwill impairment as of December 31, 2020, the future occurrence of a potential indicator of impairment, such as a significant adverse change in legal, regulatory, business or economic conditions or a more-likely-than-not expectation that the reporting unit or a significant portion of the reporting unit will be sold or disposed of, would require an interim assessment for the reporting unit prior to the next required annual assessment as of December 31, 2021.

There were no adjustments to goodwill for the six months ended November 30, 2021 other than foreign currency translation adjustments.

Definite Lived Intangible Assets

Intangible assets other than goodwill are amortized over their estimated useful lives on a straight-line basis. Useful lives range from two to eighteen years. The Company periodically reviews, and adjusts, if necessary, the estimated useful lives of its intangible assets and reviews such assets or asset groups for impairment whenever events or changes in circumstances indicate

12

that the carrying value of the assets or asset groups may not be recoverable. If an intangible asset or asset group 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.

Intangible assets consisted of the following:

	Nov 30, 2021
(in thousands)	Gross carrying value		Accumulated amortization		Net carrying value
Product technologies	$	242,907	$	(105,140)	$	137,767

Licenses	6,087		(5,846)		241
	$	313,235	$	(144,258)	$	168,977

Amortization expense for the three months ended November 30, 2021 and 2020 was $4.9 million and $4.6 million, respectively. Amortization expense for the six months ended November 30, 2021 and 2020 was $9.7 million and $9.5 million, respectively.

Expected future amortization expense related to the intangible assets for each of the following fiscal years is as follows:

(in thousands)
Remainder of 2022	$	9,796
2023	19,111
2024	16,902
2025	16,884

7. LONG-TERM DEBT

On June 3, 2019 the Company repaid all amounts outstanding under its then existing credit agreement and entered into a new Credit Agreement with the lender's party thereto, JPMorgan Chase Bank, N.A., as administrative agent, and Bank of America, N.A. and KeyBank National Association, as co-syndication agents.

The Credit Agreement provides for a $125.0 million secured revolving credit facility (the “Revolving Facility”), which includes an uncommitted expansion feature that allows the Company to increase the total revolving commitments and/or add new tranches of term loans in an aggregate amount not to exceed $75.0 million.  The proceeds may be used to refinance certain existing indebtedness of the Company and its subsidiaries, to finance the working capital needs, and for general corporate purposes (including permitted acquisitions), of the Company and its subsidiaries.

The Credit Agreement has a five-year maturity. Interest on the facility is based, at the Company’s option, on either a base rate of LIBOR or alternate base rate, plus an applicable margin tied to the Company’s total leverage ratio and having ranges between 0.25% and 0.75% for base rate loans and between 1.25% and 1.75% for LIBOR loans. After default, the interest rate may be increased by 2.0%. The facility also carries a commitment fee of 0.20% to 0.25% per annum on the unused portion.

The Company's obligations under the Revolving Facility are unconditionally guaranteed, jointly and severally, by the Company's material direct and indirect domestic subsidiaries (the “Guarantors”). All obligations of the Company and the Guarantors under the Revolving Facility are secured by first priority security interests in substantially all of the assets of the Company and the Guarantors.

The Credit Agreement includes customary representations, warranties and covenants, and acceleration, indemnity and events of default provisions, including, among other things, two quarterly financial covenants as follows: 

•Maximum leverage ratio of consolidated total indebtedness* to consolidated EBITDA* of not greater than 3.00 to 1.00 (during certain periods following material acquisitions the ratio shall be increased to 3.50 to 1.00).

•Fixed charge coverage ratio of consolidated EBITDA minus consolidated capital expenditures* to consolidated interest expense* paid or payable in cash plus scheduled principal payments in respect of indebtedness under the Credit Agreement of not less than 1.25 to 1.00.

* The definitions of consolidated total indebtedness, consolidated EBITDA, consolidated capital expenditures and consolidated interest expense are specifically defined in the Credit Agreement included as an exhibit to Form 8-K filed on June 6, 2019.

As of November 30, 2021, there was $25.0 million outstanding on the Revolving Facility. As of November 30, 2021 and May 31, 2021, the carrying value of long-term debt approximated its fair market value.

The interest rate on the Revolving Facility at November 30, 2021 was 1.34%.

8. INCOME TAXES

The Company provides for income taxes at the end of each interim period based on the estimated effective tax rate for the full fiscal year adjusted for any discrete events, which are recorded in the period that they occur.  The estimated annual effective tax rate prior to discrete items was 12.3% as of the second quarter of fiscal year 2022, as compared to 16.1% for the same period in fiscal year 2021. In fiscal year 2022, the Company’s effective tax rate differs from the U.S. statutory rate primarily due to the impact of the valuation allowance, foreign taxes, and other non-deductible permanent items (such as non-deductible meals and entertainment, Section 162(m) excess compensation and non-deductible share-based compensation).

The Company regularly assesses its ability to realize its deferred tax assets. Assessing the realization of deferred tax assets requires significant management judgment. In determining whether its deferred tax assets are more likely than not realizable, the Company evaluated all available positive and negative evidence, and weighted the evidence based on its objectivity.

Based on the review of all available evidence, the Company determined that it has not yet attained a sustained level of profitability and the objectively verifiable negative evidence outweighed the positive evidence. Therefore, the Company has provided a valuation allowance on its federal and state net operating loss carryforwards, federal and state R&D credit carryforwards and other net deferred tax assets that have a limited life and are not supportable by the naked credit deferred tax liability sourced income as of November 30, 2021. The Company will continue to assess the level of the valuation allowance required. If sufficient positive evidence exists in future periods to support a release of some or all of the valuation allowance, such a release would likely have a material impact on the Company’s results of operations.

9. SHARE-BASED COMPENSATION

On October 13, 2020, the Company's shareholders approved the 2020 Stock and Incentive Award Plan (the “2020 Plan”). The 2020 Plan provides for the grant of incentive stock options, non-statutory stock options, restricted stock, restricted stock units, stock appreciation rights, performance share units, performance shares and other incentive awards to the Company's employees, directors and other service providers. As of November 30, 2021, there was a maximum of 1.5 million shares of common stock available for future grant under the 2020 Plan.

Prior to the adoption of the 2020 Plan, equity awards were issued under the 2004 Stock and Incentive Award Plan (the “2004 Plan”). The adoption of the 2020 Plan did not impact the administration of equity awards issued under the 2004 Plan but following the adoption of the 2020 Plan, equity award grants are no longer made under the 2004 Plan.

The Company also has an employee stock purchase plan. As of November 30, 2021, there was a maximum of 2.4 million shares of common stock available for future grant under the employee stock purchase plan.

For the three months ended November 30, 2021 and 2020, share-based compensation expense was $3.0 million and $2.4 million, respectively. For the six months ended November 30, 2021 and 2020, share-based compensation expense was $5.4 million and $4.3 million, respectively.

During the six months ended November 30, 2021 and 2020, the Company granted stock options and restricted stock units under the 2020 and 2004 Plan to certain employees and members of the Board of Directors. Stock option awards are valued using the Black-Scholes option-pricing model and then amortized on a straight-line basis over the requisite service period of the award. Restricted stock unit awards are valued based on the closing trading value of the Company’s common stock on the date of grant and then amortized on a straight-line basis over the requisite service period of the award.

During the six months ended November 30, 2021 and 2020, the Company granted performance share units under the 2020 and 2004 Plan to certain employees. The awards may be earned by achieving performance levels over the requisite service period. The performance criteria are based on achieving certain performance targets and the total shareholder return (“TSR”) of the Company’s common stock relative to the TSR of the common stock of a pre-defined industry peer-group. The fair value of these awards is based on a Monte Carlo simulation model.

As of November 30, 2021, there was $22.1 million of unrecognized compensation expense related to share-based payment arrangements. These costs are expected to be recognized over a weighted-average period of approximately three years. The Company has sufficient shares to satisfy expected share-based payment arrangements.

10. EARNINGS PER SHARE

Basic earnings per share is based on the weighted average number of common shares outstanding without consideration of potential common stock. Diluted earnings per share includes the dilutive effect of potential common stock consisting of stock options, restricted stock units and performance stock units, provided that the inclusion of such securities is not anti-dilutive. In periods with a net loss, stock options and restricted stock units are not included in the computation of diluted loss per share as the impact would be anti-dilutive.

The following table reconciles basic to diluted weighted-average shares outstanding:

	Three Months Ended		Six Months Ended
(in thousands)	Nov 30, 2021	Nov 30, 2020	Nov 30, 2021	Nov 30, 2020
Basic	39,053	38,327	38,893	38,242
Effect of dilutive securities	—	—	—	—
Diluted	39,053	38,327	38,893	38,242
Securities excluded as their inclusion would be anti-dilutive	3,510	3,133	3,510	3,159

11. SEGMENT AND GEOGRAPHIC INFORMATION

The Company considers the business to be a single operating segment engaged in the development, manufacture and sale of medical devices for vascular access, peripheral vascular disease and oncology on a global basis. The Company's chief operating decision maker, the President and Chief Executive Officer (CEO), evaluates the various global product portfolios on a net sales basis utilizing various breakouts of the data including Global Business Unit, Med Tech versus Med Device and

15

geography. Executives reporting to the CEO include those responsible for commercial operations, manufacturing operations, regulatory and quality and certain corporate functions. The CEO evaluates profitability, investment and cash flow metrics on a consolidated global basis due to shared infrastructure and resources.

12. FAIR VALUE

On a recurring basis, the Company measures certain financial assets and financial liabilities at fair value based upon quoted market prices, where available. Where quoted market prices or other observable inputs are not available, the Company applies valuation techniques to estimate fair value. FASB ASC Topic 820, Fair Value Measurements and Disclosures, establishes a three-level valuation hierarchy for disclosure of fair value measurements. The categorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the measurement of fair value. The three levels of the hierarchy are defined as follows:

•Level 1 - Inputs to the valuation methodology are quoted market prices for identical assets or liabilities.

•Level 2 - Inputs to the valuation methodology are other observable inputs, including quoted market prices for similar assets or liabilities and market-corroborated inputs.

•Level 3 - Inputs to the valuation methodology are unobservable inputs based on management’s best estimate of inputs market participants would use in pricing the asset or liability at the measurement date, including assumptions about risk.

The Company's financial instruments include cash and cash equivalents, accounts receivable, accounts payable and contingent consideration. The carrying amount of cash and cash equivalents, accounts receivable, and accounts payable approximates fair value due to their immediate or short-term maturities. The recurring fair value measurements using significant unobservable inputs (Level 3) relate to contingent consideration liabilities.

16

The following tables provide information by level for assets and liabilities that are measured at fair value on a recurring basis:

	Fair Value Measurements using inputs considered as:						Fair Value at Nov 30, 2021
(in thousands)	Level 1		Level 2		Level 3
Financial Liabilities
Contingent consideration for acquisition earn outs	$	—	$	—	$	16,540	$	16,540
Total Financial Liabilities	$	—	$	—	$	16,540	$	16,540
	Fair Value Measurements using inputs considered as:						Fair Value at May 31, 2021

Total Financial Liabilities	$	—	$	—	$	15,741	$	15,741

There were no transfers between Level 1, 2 and 3 for the three and six months ended November 30, 2021 and 2020.

The table below presents the changes in fair value components of Level 3 instruments:

	Three Months Ended Nov 30, 2021
(in thousands)	Fair Value Measurements Using Significant Unobservable Inputs (Level 3)
Balance, August 31, 2021	$	15,936
Total gains or losses (realized/unrealized):
Change in present value of contingent consideration (1)	609
Currency gain from remeasurement	(5)

Balance, November 30, 2021	$	16,540

(1) Change in the fair value of contingent consideration is included in earnings and comprised of changes in estimated earn out payments based on projections of Company performance and amortization of the present value discount.

Contingent Liability for Acquisition Earn Outs

Some of the Company's business combinations involve the potential for the payment of future contingent consideration upon the achievement of certain product development milestones or various other performance conditions. Payment of the additional consideration is generally contingent on the acquired company reaching certain performance milestones, including attaining specified revenue levels or product development targets. Contingent consideration is recorded at the estimated fair value of the contingent payments on the acquisition date. The fair value of the contingent consideration is remeasured at the estimated fair value at each reporting period with the change in fair value recognized as income or expense within change in fair value of contingent consideration in the Consolidated Statements of Operations.

17

The Company measures the initial liability and remeasures the liability on a recurring basis using Level 3 inputs as defined under authoritative guidance for fair value measurements, which is determined using a discounted cash flow model applied to projected net sales, using probabilities of achieving projected net sales and projected payment dates. Projected net sales are based on internal projections and extensive analysis of the target market and the sales potential. Increases or decreases in any valuation inputs in isolation may result in a significantly lower or higher fair value measurement in the future.

The recurring Level 3 fair value measurements of the contingent consideration liabilities include the following significant unobservable inputs as of November 30, 2021:

(in thousands)	Fair Value		Valuation Technique	Unobservable Input	Range
Revenue based payments	$	16,540	Discounted cash flow	Discount rate	5%
				Probability of payment	66% - 100%
				Projected fiscal year of payment	2023 - 2025

At November 30, 2021, the amount of undiscounted future contingent consideration that the Company expects to pay as a result of all completed acquisitions is approximately $20.0 million. The milestones, including revenue projections and technical milestones associated with the contingent consideration must be reached in future periods ranging from fiscal years 2022 to 2029 in order for the associated consideration to be paid.

13. LEASES

The Company determines if an arrangement is a lease at inception of the contract. The Company has operating leases for buildings, primarily for office space, R&D, manufacturing and warehousing.

Operating lease right-of-use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. Many of the lease agreements contain renewal or termination clauses that are factored into the determination of the lease term if it is reasonably certain that these options would be exercised. The Company recognizes lease expense for these leases on a straight-line basis over the lease term.

The following table presents supplemental balance sheet information related to leases:

(in thousands)	Balance Sheet Location	Nov 30, 2021		May 31, 2021
Assets
Operating lease ROU asset	Other assets	$	8,159	$	9,382
Liabilities
Current operating lease liabilities	Other current liabilities	2,473		2,415
Non-current operating lease liabilities	Other long-term liabilities	6,011		7,319
Total lease liabilities		$	8,484	$	9,734

The interest rate implicit in lease agreements is typically not readily determinable, and as such the Company used the incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The incremental borrowing rate is defined as the interest the Company would pay to borrow on a collateralized basis, considering factors such as length of lease term. The following table presents the weighted average remaining lease term and discount rate:

	Nov 30, 2021
Weighted average remaining term (in years)	3.68
Weighted average discount rate	3.8	%

Remainder of 2022	$	1,361
2023	2,773
2024	2,195

During the three months ended November 30, 2021 and 2020, the Company recognized $0.7 million and $0.7 million of operating lease expense, respectively, which includes immaterial short-term leases. During the six months ended November 30, 2021 and 2020, the Company recognized $1.4 million and $1.6 million of operating lease expense, respectively, which includes immaterial short-term leases. The expenses on the Consolidated Statement of Operations were classified as follows:

	Three Months Ended				Six Months Ended
(in thousands)	Nov 30, 2021		Nov 30, 2020		Nov 30, 2021		Nov 30, 2020

14. COMMITMENTS AND CONTINGENCIES    

Legal Proceedings

The Company is involved in various legal proceedings, including commercial, intellectual property, product liability, and regulatory matters of a nature considered normal for its business. The Company accrues for amounts related to these matters if it is probable that a liability has been incurred, and an amount can be reasonably estimated. The Company discloses such matters when there is at least a reasonable possibility that a material loss may have been incurred. However, the Company cannot predict the outcome of any litigation or the potential for future litigation.

C.R. Bard, Inc. v. AngioDynamics, Inc.

On January 11, 2012, C.R. Bard, Inc. ("Bard") filed a suit in the United States District Court of Utah claiming certain of the Company's implantable port products infringe on three U.S. patents held by Bard (US Patent Nos. 7,785,302 (“’302 Patent”), 7,959,615 (“’615 Patent”) and 7,947,022 (“’022 Patent”)). The case was stayed pending reexamination in the US Patent and Trademark Office ("USPTO"). Following the reexamination proceedings, and the parties’ related appeals to the Federal Circuit which resulted in further proceedings at the USPTO, certain claims of the ‘615 Patent were held invalid, while the remaining claims of the ‘615 Patent and the other two patents were upheld over the prior art references considered in the reexamination proceedings. Thereafter, the case was transferred from the District of Utah to the United States District Court for the District of Delaware ("District of Delaware"). A scheduling order was entered on March 23, 2021. On July 22, 2021, in

19

another case against a different defendant the District of Utah invalidated multiple claims of the ‘302, ‘022, and ‘615 Patents under 35 USC §101, including claims asserted against the Company. Following the Utah court’s decision, the Company filed a Motion for Judgment on the Pleadings based on collateral estoppel on August 9, 2021. Bard filed its opposition brief on September 2, 2021 and the Company filed a reply on September 9, 2021. Following a hearing on the Motion for Judgment on the Pleadings on December 21, 2021, the District of Delaware stayed the case pending the Federal Circuit's resolution of Bard's appeal from the Utah Decision. Previously, the Company had filed a Motion for Leave to Amend its Answer and Counterclaims on April 14, 2021. This motion sought to add counterclaims for infringement of U.S. Patent Nos. 9,168,365; 9,895,523; and 10,632,295, as well as a counterclaim of inequitable conduct. On November 5, 2021, the Company notified the District of Delaware that the Utah decision was certified for appeal to the Court of Appeals for the Federal Circuit. Contemporaneously, the Company withdrew its Motion for Leave to Amend its Answer and Counterclaims without prejudice to refile. Bard filed its Opening Appellate Brief in its appeal at the Federal Circuit on December 8, 2021. The Company believes these claims are without merit and intends to defend them vigorously. The Company has not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable nor reasonably estimable.

On March 10, 2015, Bard and Bard Peripheral Vascular filed suit in the District of Delaware claiming certain of the Company's implantable port products infringe on three U.S. patents held by Bard (US Patent Nos. 8,475,417, 8,545,460, 8,805,478). The case proceeded through trial which began on March 4, 2019. At the close of Bard’s case, the Court granted the Company's oral motion for judgment as a matter of law as well as its motions for summary judgment on the grounds that the asserted patents are invalid, ineligible, not infringed and not willfully infringed. On May 10, 2019, the Company filed a motion for attorney fees and non-taxable expenses under 35 USC Sec. 285. Bard appealed the judgment to the Federal Circuit and on November 10, 2020, the Federal Circuit reversed the judgment in part with respect to Section 101 (subject matter eligibility), and vacated and remanded the trial court’s invalidity and non-infringement judgments. The Company filed a combined Petition for rehearing and rehearing en banc on December 10, 2020, which was denied on January 15, 2021. The Federal Circuit issued its mandate on January 22, 2021. On March 15, 2021, the District of Delaware entered an order requiring the parties to submit status reports and denied as moot the Company’s motion for attorney’s fees and expenses. The parties agreed to schedule trial the week of May 9, 2022, and the trial has been docketed on the Court's calendar. The Company maintains its belief that Bard’s claims are without merit. The Company has not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable nor reasonably estimable.

On March 8, 2021, Bard filed suit in the District of Delaware asserting certain of the Company’s port products (including certain related infusion sets) infringe U.S. Patent Nos. 8,025,639, 9,603,992 (“’992”) and 9,603,993 (“’993”). On May 20, 2021, the Company filed a Motion to Dismiss Bard’s claims with respect to the ’992 and ’993 patents. On July 22, 2021, the Company submitted the Utah court’s decision invalidating claims of the related ‘302, ‘022, and ‘615 Patents as supplemental authority in support of its Motion to Dismiss. The parties agreed to submit supplemental briefing to address the Utah court’s decision. Bard submitted its brief on August 12, 2021, and the Company submitted its reply on September 2, 2021. On December 21, 2021, the District of Delaware stayed the case pending the Federal Circuit's resolution of Bard's appeal of the Utah decision invalidating multiple claims the ‘302, ‘022, and ‘615 patents under 35 USC §101. The Company maintains its belief that Bard’s claims of the related are without merit. The Company has not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable nor reasonably estimable.

AngioDynamics, Inc. v. C.R. Bard, Inc.

On May 30, 2017, the Company commenced an action in the United States District Court for the Northern District of New York entitled AngioDynamics, Inc. v. C.R. Bard, Inc. and Bard Access Systems, Inc. (“Bard”). In this action, the Company alleges that Bard has illegally tied the sales of its tip location systems to the sales of its PICCs. The Company alleges that this practice violates the federal antitrust laws and has had, and continues to have, an anti-competitive effect in the market for PICCs. The Company seeks both monetary damages and injunctive relief. Bard moved to dismiss on September 8, 2017. On August 6, 2018 the court denied Bard’s motion in its entirety. Bard made a motion for summary judgment which was denied in its entirety in a decision issued by the Court on May 5, 2021. Bard also raised a series of challenges targeted at one of AngioDynamics’ expert witnesses, which the Court denied in part and granted in part in decisions on May 5, 2021 and June 11, 2021. Discovery is largely complete, and trial is scheduled to commence on July 5, 2022.

Executive Overview

We design, manufacture and sell a wide range of medical, surgical and diagnostic devices used by professional healthcare providers for vascular access, for the treatment of peripheral vascular disease and for use in oncology and surgical settings. Our devices are generally used in minimally invasive, image-guided procedures. Many of our products are intended to be used once and then discarded, or they may be temporarily implanted for short- or longer-term use.

Our business operations cross a variety of markets. Our financial performance is impacted by changing market dynamics, which have included an emergence of value-based purchasing by healthcare providers, consolidation of healthcare providers, the increased role of the consumer in health care decision-making and an aging population, among others. In addition, our growth is impacted by changes within our sector, such as the merging of competitors to gain scale and influence; changes in the regulatory environment for medical devices; and fluctuations in the global economy.

Our sales and profitability growth also depends, in part, on the introduction of new and innovative products, together with ongoing enhancements to our existing products. Expansions of our product offerings are created through internal and external product development, technology licensing and strategic alliances. We recognize the importance of, and intend to continue to

23

make investments in research and development activities and selective business development opportunities to provide growth opportunities.

We sell our products in the United States primarily through a direct sales force, and outside the U.S. through a combination of direct sales and distributor relationships. Our end users include interventional radiologists, interventional cardiologists, vascular surgeons, urologists, interventional and surgical oncologists and critical care nurses. We expect our businesses to grow in both sales and profitability by expanding geographically, penetrating new markets, introducing new products and increasing our presence internationally.

The COVID-19 global pandemic has impacted our business and may continue to pose future risks with the emergence of new variants. Even with the public health actions that have been taken to reduce the spread of the virus, the market continues to experience disruptions with respect to consumer demand, hospital operating procedures and workflow, trends that may continue. The Company's ability to manufacture products, the reliability of our supply chain, labor shortages, backlog and inflation (including the cost of raw materials, direct labor and shipping) have impacted our business, trends that may continue. Accordingly, management continues to evaluate the Company’s liquidity position, communicate with and monitor the actions of our customers and suppliers, and review our near-term financial performance.

In evaluating the operating performance of our business, management focuses on revenue, gross margin, operating income, earnings per share and cash flow from operations. A summary of these key financial metrics for the three and six months ended November 30, 2021 compared to the three and six months ended November 30, 2020 are as follows:

Three months ended November 30, 2021:

•Revenue increased by 7.6% to $78.3 million.

•Med Tech growth of 36.4% and Med Device growth of 0.8%.

•Gross profit decreased 340 bps to 51.8%.

•Net loss increased by $4.1 million to $8.4 million.

•Loss per share increased by $0.10 to a loss of $0.21.

Six months ended November 30, 2021:

•Revenue increased by 8.6% to $155.3 million.

•Med Tech growth of 50.0% and Med Device growth of 0.1%.

•Gross profit decreased 110 bps to 52.0%.

•Net loss increased by $6.8 million to $15.3 million.

•Loss per share increased by $0.17 to a loss of $0.39.

•Cash used in operations increased by $13.0 million to $7.0 million.

In our Med Tech business, comprised of Auryon, the Thrombectomy portfolio and NanoKnife, Auryon and the Thrombectomy portfolio experienced improved performance during the second quarter of fiscal year 2022 as the number of procedures increased. In our Med Device business, Vascular Access, also improved in the second quarter of fiscal year 2022 compared to the prior year period. This was partially offset by our Oncology products, which continued to face pressure from reductions in procedure volumes due to challenges resulting from the COVID-19 pandemic.

For the three months ended November 30, 2021, net sales increased $5.5 million to $78.3 million compared to the same period in the prior year. For the six months ended November 30, 2021, net sales increased $12.3 million to $155.3 million compared to the same period in the prior year. At November 30, 2021, the Company had a backlog of $4.0 million.

The Med Tech business net sales increased $5.0 million and $12.2 million for the three and six months ended November 30, 2021 compared to the same periods in the prior year, respectively. The change in sales for both periods was primarily driven by:

•Increased Auryon sales of $4.2 million and $9.0 million compared to the same periods in the prior year, respectively;

•Growth in the thrombectomy platform driven by the AngioVac business of $1.2 million and $1.9 million, compared to the same periods in the prior year, respectively, as the Company saw increased case volumes in AngioVac despite continued COVID-19 challenges along with the limited market launch of the AlphaVac product during the second quarter of fiscal year 2022; and

•Decreased NanoKnife sales of $0.7 million for the three months ended November 30, 2021 compared to the same period in the prior year and increased NanoKnife sales of $1.0 million for the six months ended November 30, 2021 compared to the same period in the prior year. The decrease for the three months ended November 30, 2021 was driven by decreased capital sales offset by a $0.2 million increase in disposable sales, mainly in Europe. For the six months ended November 30, 2021, NanoKnife disposable sales increased $1.0 million, driven by sales in the U.S. and Europe, with consistent capital sales.

The Med Device business net sales increased $0.5 million and $0.1 million for the three and six months ended November 30, 2021 compared to the same periods in the prior year, respectively. Excluding the large UK order in the first quarter of the prior year, net sales increased $5.3 million for the six months ended November 30, 2021. The change in sales for both periods was primarily driven by:

•Increased case volume for the three months ended November 30, 2021 compared to the same period in the prior year which resulted in increased sales of Core and BioSentry products of $0.7 million and $0.1 million, respectively. PICCs and Port sales also increased $0.9 million and $0.6 million, respectively with the increase in PICCs driven by sales in the U.S. and Latin America and the increase in Ports driven solely by sales in the U.S. These increases for the three months ended November 30, 2021 compared to the same period in the prior year were partially offset by decreased Venous, Midline, Radio Frequency Ablation, Microwave and Balloon sales of $0.7 million, $0.2 million, $0.5 million, $0.2 million and $0.1 million, respectively;

25

•Increased case volume for the six months ended November 30, 2021 compared to the same period in the prior year, which resulted in increased sales of Core and BioSentry products of $2.9 million and $0.4 million, respectively. Port sales also increased $1.9 million, driven primarily by sales in the U.S. These increases for the six months ended November 30, 2021 compared to the same period in the prior year were partially offset by decreased Venous, Midline, PICCs, Dialysis, Radio Frequency Ablation and Microwave sales of $0.1 million, $2.0 million, $1.6 million, $0.4 million, $0.4 million and $0.6 million, respectively;

•Midlines, PICCs and Ports increased $3.5 million, excluding the prior year order in the UK, for the six months ended November 30, 2021 compared to the prior year period; and

•The backlog of $4.0 million at November 30, 2021, which was primarily related to Med Device products.

Gross profit - Gross profit consists of net sales less the cost of goods sold, which includes the costs of materials, products purchased from third parties and sold by us, manufacturing personnel, royalties, freight, business insurance, depreciation of property and equipment and other manufacturing overhead, exclusive of intangible amortization.

Gross profit increased by $0.4 million for the three months ended November 30, 2021 compared to the same period in the prior year. The change is primarily attributable to the following:    

•Sales volume positively impacted gross profit by $3.3 million;

•Price and mix negatively impacted gross profit by $0.4 million as a result of increased sales of Vascular Access products and decreased sales of NanoKnife capital. This negative impact was partially offset by increased sales of Auryon and AngioVac products;

•Labor shortages, inflationary costs on raw materials and production volume negatively impacted gross profit by $1.7 million; and

•Start-up costs related to Auryon and AlphaVac of $0.8 million, including depreciation on Auryon placement units of $0.4 million, negatively impacted gross profit.

Gross profit increased by $4.8 million for the six months ended November 30, 2021 compared to the same period in the prior year. The change is primarily attributable to the following:    

•Sales volume positively impacted gross profit by $6.9 million;

•Price and mix positively impacted gross profit by $1.3 million as a result of increased sales of Auryon and AngioVac products. This positive impact was partially offset by increased sales of Vascular Access products;

•Start-up costs related to Auryon and AlphaVac of $1.7 million, including depreciation on Auryon placement units of $0.6 million, negatively impacted gross profit; and

•Labor shortages, freight and inflationary costs on raw materials, negatively impacted gross profit by $1.7 million year over year.

Research and development expense - Research and development (“R&D”) expense includes internal and external costs to develop new products, enhance existing products, validate new and enhanced products, and manage clinical, regulatory and medical affairs.

R&D expense decreased $1.5 million and $3.1 million for the three and six months ended November 30, 2021 compared to the same period in the prior year, respectively. The change from each period is primarily attributable to:

26

•The timing of certain projects, which reduced R&D project expense by $0.7 million and $2.1 million for the three and six months ended November 30, 2021 compared to the same periods in the prior year, respectively; and

•Open R&D positions, which resulted in decreased compensation and benefits expense of $0.7 and $1.1 million for the three and six months ended November 30, 2021 compared to the same periods in the prior year, respectively.

Sales and marketing expense - Sales and marketing (“S&M”) expense consists primarily of salaries, commissions, travel and related business expenses, attendance at medical society meetings, product promotions and marketing activities.

S&M expense increased $3.4 million and $10.2 million for the three and six months ended November 30, 2021 compared to the same period in the prior year, respectively. The change from each period is primarily attributable to:

•Additional headcount from the build-out of the Auryon sales and marketing teams, which increased compensation and benefits expense by $2.5 million and $6.8 million for the three and six months ended November 30, 2021 compared to the same periods in the prior year, respectively; and

•Increased travel, meeting and tradeshow expenses of $1.0 million and $3.2 million for the three and six months ended November 30, 2021 compared to the same period in the prior year, respectively, as some COVID-19 restrictions were lifted.

General and administrative expense - General and administrative (“G&A”) expense includes executive management, finance, information technology, human resources, business development, legal, and the administrative and professional costs associated with those activities.

G&A expense increased $0.5 million and $0.8 million for the three and six months ended November 30, 2021 compared to the same period in the prior year, respectively. The change from each period is primarily attributable to:

•Additional headcount, which increased compensation and benefits expense by $0.5 million and $1.3 million for the three and six months ended November 30, 2021 compared to the same period in the prior year, respectively; and

•Legal expense decreased $1.4 million offset by other outside consultant spend of $0.8 million for the six months ended November 30, 2021 compared to the same period in the prior year.

Amortization of intangibles - Represents the amount of amortization expense that was taken on intangibles assets held by the Company.

•Amortization expense increased $0.3 million and $0.2 million, respectively, for the three and six months ended November 30, 2021 compared to the prior year periods. The increase is due to amortization relating to the Camaro intangible asset addition of $3.9 million in the first quarter of fiscal year 2022, partially offset by assets that became fully amortized in fiscal year 2021.

Change in fair value of contingent consideration - Represents changes in contingent consideration driven by changes to estimated future payments on earn-out liabilities created through acquisitions and amortization of present value discounts on long-term contingent consideration.

•The change in the fair value for the three and six months ended November 30, 2021 is related to the Eximo contingent consideration.

Acquisition, restructuring and other items, net - Represents costs associated with mergers and acquisitions, restructuring expenses, legal costs that are related to litigation that is not in the ordinary course of business, legal settlements and other one-time items.

27

Acquisition, restructuring and other items, net, increased by $1.1 million and $2.2 million for the three and six months ended November 30, 2021, respectively, compared to the same period in the prior year. The change from each period is primarily attributable to:

•Legal expense, related to litigation that is outside of the normal course of business, which increased $0.9 million and $2.2 million, respectively, for the three and six months ended November 30, 2021 compared to the same period in the prior year, respectively.

Other income (expense), net - Other expenses include interest expense, foreign currency impacts, bank fees, and amortization of deferred financing costs.

•The change in other expense of $0.2 million and $0.7 million for the three and six months ended November 30, 2021 compared to the same period in the prior year, respectively, is primarily due to unrealized foreign currency fluctuations of $0.1 million and $0.8 million, respectively.

Effective tax rate including discrete items	5.8		%	17.5		%	12.3		%	14.5		%

Our effective tax rate including discrete items for the three-month periods ended November 30, 2021 and 2020 was 5.8% and 17.5%, respectively. Our effective tax rate including discrete items for the six-month periods ended November 30, 2021 and 2020 was 12.3% and 14.5%, respectively. In fiscal year 2022, the Company’s effective tax rate differs from the U.S. statutory rate primarily due to the impact of the valuation allowance, foreign taxes, and other non-deductible permanent items (such as non-deductible meals and entertainment, Section 162(m) excess compensation and non-deductible share-based compensation).

Liquidity and Capital Resources

We regularly review our liquidity and anticipated capital requirements in light of the significant uncertainty created by the COVID-19 global pandemic. We believe that our current cash on hand and availability under our Revolving Facility provide sufficient liquidity to meet our anticipated needs for capital for at least the next 12 months. We are closely monitoring receivables and payables.

Our cash and cash equivalents totaled $34.3 million as of November 30, 2021, compared with $48.2 million as of May 31, 2021. As of November 30, 2021 and May 31, 2021, total debt outstanding related to the Revolving Facility was $25.0 million and $20.0 million, respectively. The fair value of contingent consideration liability as of November 30, 2021 and May 31, 2021, was $16.5 million and $15.7 million, respectively.

The table below summarizes our cash flows:

Cash flows consisted of the following:

Cash provided by (used in) operating activities

Six months ended November 30, 2021 and 2020:

•Net loss of $15.3 million and $8.5 million for the period ended November 30, 2021 and 2020, respectively, plus the non-cash items, primarily driven by depreciation and amortization and stock based compensation, along with the

28

changes in working capital below, contributed to cash used in operations of $7.0 million and cash provided by operations of $6.0 million, respectively, for these periods.

•For the period ended November 30, 2021, working capital was negatively impacted by decreased accounts payable, accrued liabilities and other liabilities of $4.5 million, mainly driven by the payment of annual incentive compensation in the first quarter along with increased accounts receivable of $2.9 million.

•For the period ended November 30, 2020, working capital was negatively impacted by increased accounts receivable of $2.3 million and decreased accounts payable, accrued liabilities and other liabilities of $3.8 million. Inventory had a favorable impact on working capital of $10.5 million.

Cash used in investing activities

Six months ended November 30, 2021 and 2020:

•$2.2 million and $3.2 million, respectively, of cash was used for fixed asset additions;

•$7.2 million of cash was used for Auryon placement and evaluation unit additions in fiscal year 2022; and

•$3.6 million of cash was used for the QX Medical asset acquisition in the first quarter of fiscal year 2022.

Cash provided by financing activities

Six months ended November 30, 2021 and 2020:

•$5.0 million draw on the revolver in the first quarter of fiscal year 2022 for the QX Medical asset acquisition; and

•$1.4 million and $0.5 million, respectively, of proceeds from stock option and ESPP activity.

The Credit Agreement provides for a $125.0 million secured Revolving Facility, which includes an uncommitted expansion feature that allows the Company to increase the total revolving commitments and/or add new tranches of term loans in an aggregate amount not to exceed $75.0 million.  The Credit Agreement includes customary representations, warranties and covenants, and acceleration, indemnity and events of default provisions, including, among other things, two financial covenants. One financial covenant requires us to maintain a fixed charge coverage ratio of not less than 1.25 to 1.00. The other financial covenant requires us to maintain a total leverage ratio of not greater than 3.00 to 1.00. The total leverage ratio is based upon our trailing twelve months total adjusted EBITDA (as defined in the Credit Agreement). The amount that we can borrow under our Credit Agreement is directly based on our leverage ratio. The interest rate on the Revolving Facility at November 30, 2021 was 1.34%. The Company was in compliance with the Credit Agreement covenants as of November 30, 2021.

In the first quarter of fiscal year 2022, the Company made a $5.0 million draw on the Revolving Facility in conjunction with the QX Medical asset acquisition. In December 2020 and March 2021, payments of $10.0 million each were made on the Revolving Facility. We believe that our current cash balance, together with cash generated from operations and access to our Revolving Facility, will provide sufficient liquidity to meet our anticipated needs for capital for at least the next 12 months. If we seek to make acquisitions of other businesses or technologies in the future for cash, we may require external financing.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Foreign Currency Exchange Rate Risk

We are exposed to market risk from changes in currency exchange rates, as well as interest rate fluctuations on our credit facility and investments that could impact our results of operations and financial position.

We transact sales in currencies other than the U.S. Dollar, particularly the Euro, British pound and Canadian dollar. For the six months ended November 30, 2021, approximately 7% of our sales were denominated in foreign currencies. We do not have expenses denominated in foreign currencies at the level of our sales and as a result, our profitability is exposed to currency fluctuations. When the U.S. Dollar strengthens, our sales and gross profit will be negatively impacted. In addition, we have assets and liabilities denominated in non-functional currencies which are remeasured at each reporting period, with the offset to changes presented as a component of Other (Expenses) Income. Significant non-functional balances include accounts receivable due from a sub-section of our international customers.

Interest Rate Risk

We have a Credit Agreement which provides for a $125.0 million Revolving Facility. Interest on the facility will be based, at the Company’s option, on either a base rate of LIBOR or alternate base rate, plus an applicable margin tied to the Company’s total leverage ratio and having ranges between 0.25% and 0.75% for base rate loans and between 1.25% and 1.75% for LIBOR loans. In the event of default, the interest rate may be increased by 2.0%. As of November 30, 2021 there was $25.0 million outstanding on the Revolving Facility. The interest rate on the Revolving Facility at November 30, 2021 was 1.34%.

Concentration of Credit Risk

Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist primarily of cash and cash equivalents, our credit facility and trade accounts receivable.

The Company maintains cash and cash equivalents at various institutions and performs periodic evaluations of the relative credit standings of these financial institutions to ensure their credit worthiness. In addition, the Credit Agreement is structured across five above investment grade banks. The Company has the ability to draw equally amongst the five banks which limits the concentration of credit risk of one institution.

Concentration of credit risk with respect to trade accounts receivable is limited due to the large number of customers that purchase products from the Company. No single customer represents more than 10% of total sales. The Company monitors the creditworthiness of its customers. As the Company’s standard payment terms are 30 to 90 days from invoicing, the Company does not provide any significant financing to its customers. Although the Company does not currently foresee a significant credit risk associated with the outstanding accounts receivable, repayment is dependent upon the financial stability of our customers.

Item 4. Controls and Procedures.

Evaluation of disclosure controls and procedures

As of the end of the period covered by this report, our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report were effective to provide reasonable assurance that the information required to be disclosed by us in reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting for the fiscal quarter ended November 30, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Revenue from Contracts with Customers

REVENUE FROM CONTRACTS WITH CUSTOMERS

Revenue Recognition

Under ASC 606, Revenue from Contracts with Customers, revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

The Company has one primary revenue stream which is the sales of its products.

Disaggregation of Revenue

As the Company has previously announced, the Company is focused on its ongoing transformation from a company with a broad portfolio of largely undifferentiated products to a more focused medical technology company that delivers unique and innovative health care solutions. The Company believes that this transformation will enable the Company to shift the portfolio from the mature, lower-growth markets where we have competed in the past by investing in technology and products that provide access to larger and faster growing markets. As such, we believe the growth in the near to mid-term will be driven by our high technology products including Auryon, Thrombectomy (which includes AngioVac, AlphaVac and thrombolytics) and NanoKnife. We will refer to these high technology products as our Med Tech business and we will refer to the remainder of the portfolio as our Med Device business.

The following table summarizes net sales by Med Tech and Med Device:

Net Product Revenue

The Company's products consist of a wide range of medical, surgical and diagnostic devices used by professional healthcare providers for vascular access, for the treatment of peripheral vascular disease and for use in oncology and surgical settings. The Company's devices are generally used in minimally invasive, image-guided procedures. Most of the Company's products are intended to be used once and then discarded, or they may be implanted for short or long term use. The Company sells its products to its distributors and to end users, such as interventional radiologists, interventional cardiologists, vascular surgeons, urologists, interventional and surgical oncologists and critical care nurses.

Contracts and Performance Obligations

The Company contracts with its customers based on customer purchase orders, which in many cases are governed by master purchasing agreements. The Company’s contracts with customers are generally for product only, and do not include other performance obligations such as services or other material rights. As part of its assessment of each contract, the Company evaluates certain factors including the customer’s ability to pay (or credit risk). For each contract, the Company considers the promise to transfer products, each of which is distinct, to be the identified performance obligations.

Transaction Price and Allocation to Performance Obligations

Transaction prices of products are typically based on contracted rates. Product revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products to a customer, net of any variable consideration as described below.

If a contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products underlying each performance obligation. The Company has standard pricing for its products and determines standalone selling prices based on the price at which the performance obligation is sold separately.

Revenue Recognition

Revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied), which occurs at a point in time, and may be upon shipment from the Company’s manufacturing site or delivery to the customer’s named location, based on the contractual shipping terms of a contract.

In determining whether control has transferred, the Company considers if there is a present right to payment from the customer and when physical possession, legal title and risks and rewards of ownership have transferred to the customer.

The Company typically invoices customers upon satisfaction of identified performance obligations. As the Company’s standard payment terms are 30 to 90 days from invoicing, the Company does not provide any significant financing to its customers.

The Company enters into agreements to place placement and evaluation units (“units”) at customer sites, but the Company retains title to the units. During the duration of these agreements the customer has the right to use the unit at no upfront charge in connection with the customer’s ongoing purchase of disposables. These types of agreements include an embedded operating lease for the right to use the units. In these arrangements, revenue recognized for the sale of the disposables is not allocated between the disposal revenue and lease revenue due to the insignificant value of the units in relation to the total agreement value.

Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

Variable Consideration

Reserves: Revenue from product sales are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established for discounts, returns, rebates and allowances that are offered within contracts between the Company and its customers. These reserves are based on the amounts earned or to be claimed on the related sales and are classified as a contra asset.

Rebates and Allowances: The Company provides certain customers with rebates and allowances that are explicitly stated in the Company’s contracts and are recorded as a reduction of revenue in the period the related product revenue is recognized. The Company establishes reserves for such amounts, which is included in accrued expenses in the accompanying Consolidated Balance Sheets. These rebates and allowances result from performance-based offers that are primarily based on attaining contractually specified sales volumes. The Company is also required to pay administrative fees to group purchasing organizations.

Product Returns: The Company generally offers customers a limited right of return. Product returns after 30 days must be pre-approved by the Company and customers may be subject to a 20% restocking charge. To be accepted, a returned product must be unadulterated, undamaged and have at least twelve months remaining prior to its expiration date. The Company estimates the amount of its product sales that may be returned by its customers and records this estimate as a reduction of revenue in the period the related product revenue is recognized. The Company currently estimates product return liabilities using its historical product return information and considers other factors that it believes could significantly impact its expected returns, including product recalls. During the six months ended November 30, 2021, such product returns were not material.

Contract Balances with Customers

A receivable is generally recognized in the period the Company ships the product. Payment terms on invoiced amounts are based on contractual terms with each customer and generally coincide with revenue recognition. Accordingly, the Company does not have any contract assets associated with the future right to invoice its customers. In some cases, if control of the product has not yet transferred to the customer or the timing of the payments made by the customer precedes the Company’s fulfillment of the performance obligation, the Company recognizes a contract liability that is included in deferred revenue in the accompanying Consolidated Balance Sheets.

The following table presents changes in the Company’s receivables, contract assets and contract liabilities with customers:

(in thousands)	Nov 30, 2021		May 31, 2021
Receivables	$	38,205	$	35,405
Contract assets	$	—	$	—
Contract liabilities	$	690	$	426

During the six months ended November 30, 2021, the Company had additions to contract liabilities of $0.8 million. This was offset by $0.5 million in revenue that was recognized during the six months ended November 30, 2021.

Costs to Obtain or Fulfill a Customer Contract

Under ASC 606, the Company may recognize an asset for incremental costs of obtaining a contract with a customer if it expects to recover those costs. The Company’s sales incentive compensation plans qualify for capitalization since these plans are directly related to sales achieved during a period of time. However, the Company has elected the practical expedient under ASC 340-40-25-4 to expense the costs as they are incurred within selling and marketing expenses since the amortization period is less than one year.

The Company accounts for shipping and handling activities related to contracts with customers as costs to fulfill the promise to transfer the associated products. Shipping and handling costs, associated with the distribution of finished products to customers, are recorded in costs of goods sold and are recognized when the related finished product is shipped to the customer. Amounts charged to customers for shipping and handling are recorded in net sales.

Goodwill and Intangible Assets

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Intangible Assets

GOODWILL AND INTANGIBLE ASSETS

Goodwill

Goodwill is not amortized, but rather, is tested for impairment annually or more frequently if impairment indicators arise. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in each business combination.

The Company's annual testing for impairment of goodwill was completed as of December 31, 2020. The Company operates as a single operating segment with one reporting unit and consequently evaluates goodwill for impairment based on an evaluation of the fair value of the Company as a whole. The Company determines the fair value of the reporting unit based on the market valuation approach and concluded that it was not more-likely-than-not that the fair value of the Company's reporting unit was less than its carrying value.

Even though the Company determined that there was no goodwill impairment as of December 31, 2020, the future occurrence of a potential indicator of impairment, such as a significant adverse change in legal, regulatory, business or economic conditions or a more-likely-than-not expectation that the reporting unit or a significant portion of the reporting unit will be sold or disposed of, would require an interim assessment for the reporting unit prior to the next required annual assessment as of December 31, 2021.

There were no adjustments to goodwill for the six months ended November 30, 2021 other than foreign currency translation adjustments.

Definite Lived Intangible Assets

Intangible assets other than goodwill are amortized over their estimated useful lives on a straight-line basis. Useful lives range from two to eighteen years. The Company periodically reviews, and adjusts, if necessary, the estimated useful lives of its intangible assets and reviews such assets or asset groups for impairment whenever events or changes in circumstances indicate

that the carrying value of the assets or asset groups may not be recoverable. If an intangible asset or asset group 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.

Intangible assets consisted of the following:

Long-Term Debt

LONG-TERM DEBT

On June 3, 2019 the Company repaid all amounts outstanding under its then existing credit agreement and entered into a new Credit Agreement with the lender's party thereto, JPMorgan Chase Bank, N.A., as administrative agent, and Bank of America, N.A. and KeyBank National Association, as co-syndication agents.

The Credit Agreement provides for a $125.0 million secured revolving credit facility (the “Revolving Facility”), which includes an uncommitted expansion feature that allows the Company to increase the total revolving commitments and/or add new tranches of term loans in an aggregate amount not to exceed $75.0 million.  The proceeds may be used to refinance certain existing indebtedness of the Company and its subsidiaries, to finance the working capital needs, and for general corporate purposes (including permitted acquisitions), of the Company and its subsidiaries.

The Credit Agreement has a five-year maturity. Interest on the facility is based, at the Company’s option, on either a base rate of LIBOR or alternate base rate, plus an applicable margin tied to the Company’s total leverage ratio and having ranges between 0.25% and 0.75% for base rate loans and between 1.25% and 1.75% for LIBOR loans. After default, the interest rate may be increased by 2.0%. The facility also carries a commitment fee of 0.20% to 0.25% per annum on the unused portion.

The Company's obligations under the Revolving Facility are unconditionally guaranteed, jointly and severally, by the Company's material direct and indirect domestic subsidiaries (the “Guarantors”). All obligations of the Company and the Guarantors under the Revolving Facility are secured by first priority security interests in substantially all of the assets of the Company and the Guarantors.

The Credit Agreement includes customary representations, warranties and covenants, and acceleration, indemnity and events of default provisions, including, among other things, two quarterly financial covenants as follows: 

•Maximum leverage ratio of consolidated total indebtedness* to consolidated EBITDA* of not greater than 3.00 to 1.00 (during certain periods following material acquisitions the ratio shall be increased to 3.50 to 1.00).

•Fixed charge coverage ratio of consolidated EBITDA minus consolidated capital expenditures* to consolidated interest expense* paid or payable in cash plus scheduled principal payments in respect of indebtedness under the Credit Agreement of not less than 1.25 to 1.00.

* The definitions of consolidated total indebtedness, consolidated EBITDA, consolidated capital expenditures and consolidated interest expense are specifically defined in the Credit Agreement included as an exhibit to Form 8-K filed on June 6, 2019.

As of November 30, 2021, there was $25.0 million outstanding on the Revolving Facility. As of November 30, 2021 and May 31, 2021, the carrying value of long-term debt approximated its fair market value.

The interest rate on the Revolving Facility at November 30, 2021 was 1.34%.

Income Tax Disclosure [Abstract]

Income Taxes

INCOME TAXES

The Company provides for income taxes at the end of each interim period based on the estimated effective tax rate for the full fiscal year adjusted for any discrete events, which are recorded in the period that they occur.  The estimated annual effective tax rate prior to discrete items was 12.3% as of the second quarter of fiscal year 2022, as compared to 16.1% for the same period in fiscal year 2021. In fiscal year 2022, the Company’s effective tax rate differs from the U.S. statutory rate primarily due to the impact of the valuation allowance, foreign taxes, and other non-deductible permanent items (such as non-deductible meals and entertainment, Section 162(m) excess compensation and non-deductible share-based compensation).

The Company regularly assesses its ability to realize its deferred tax assets. Assessing the realization of deferred tax assets requires significant management judgment. In determining whether its deferred tax assets are more likely than not realizable, the Company evaluated all available positive and negative evidence, and weighted the evidence based on its objectivity.

Based on the review of all available evidence, the Company determined that it has not yet attained a sustained level of profitability and the objectively verifiable negative evidence outweighed the positive evidence. Therefore, the Company has provided a valuation allowance on its federal and state net operating loss carryforwards, federal and state R&D credit carryforwards and other net deferred tax assets that have a limited life and are not supportable by the naked credit deferred tax liability sourced income as of November 30, 2021. The Company will continue to assess the level of the valuation allowance required. If sufficient positive evidence exists in future periods to support a release of some or all of the valuation allowance, such a release would likely have a material impact on the Company’s results of operations.

Share-based Payment Arrangement [Abstract]

Share-Based Compensation

SHARE-BASED COMPENSATION

On October 13, 2020, the Company's shareholders approved the 2020 Stock and Incentive Award Plan (the “2020 Plan”). The 2020 Plan provides for the grant of incentive stock options, non-statutory stock options, restricted stock, restricted stock units, stock appreciation rights, performance share units, performance shares and other incentive awards to the Company's employees, directors and other service providers. As of November 30, 2021, there was a maximum of 1.5 million shares of common stock available for future grant under the 2020 Plan.

Prior to the adoption of the 2020 Plan, equity awards were issued under the 2004 Stock and Incentive Award Plan (the “2004 Plan”). The adoption of the 2020 Plan did not impact the administration of equity awards issued under the 2004 Plan but following the adoption of the 2020 Plan, equity award grants are no longer made under the 2004 Plan.

The Company also has an employee stock purchase plan. As of November 30, 2021, there was a maximum of 2.4 million shares of common stock available for future grant under the employee stock purchase plan.

For the three months ended November 30, 2021 and 2020, share-based compensation expense was $3.0 million and $2.4 million, respectively. For the six months ended November 30, 2021 and 2020, share-based compensation expense was $5.4 million and $4.3 million, respectively.

During the six months ended November 30, 2021 and 2020, the Company granted stock options and restricted stock units under the 2020 and 2004 Plan to certain employees and members of the Board of Directors. Stock option awards are valued using the Black-Scholes option-pricing model and then amortized on a straight-line basis over the requisite service period of the award. Restricted stock unit awards are valued based on the closing trading value of the Company’s common stock on the date of grant and then amortized on a straight-line basis over the requisite service period of the award.

During the six months ended November 30, 2021 and 2020, the Company granted performance share units under the 2020 and 2004 Plan to certain employees. The awards may be earned by achieving performance levels over the requisite service period. The performance criteria are based on achieving certain performance targets and the total shareholder return (“TSR”) of the Company’s common stock relative to the TSR of the common stock of a pre-defined industry peer-group. The fair value of these awards is based on a Monte Carlo simulation model.

As of November 30, 2021, there was $22.1 million of unrecognized compensation expense related to share-based payment arrangements. These costs are expected to be recognized over a weighted-average period of approximately three years. The Company has sufficient shares to satisfy expected share-based payment arrangements.

Earnings Per Share

EARNINGS PER SHARE

Basic earnings per share is based on the weighted average number of common shares outstanding without consideration of potential common stock. Diluted earnings per share includes the dilutive effect of potential common stock consisting of stock options, restricted stock units and performance stock units, provided that the inclusion of such securities is not anti-dilutive. In periods with a net loss, stock options and restricted stock units are not included in the computation of diluted loss per share as the impact would be anti-dilutive.

Fair Value Disclosures [Abstract]

Fair Value

FAIR VALUE

On a recurring basis, the Company measures certain financial assets and financial liabilities at fair value based upon quoted market prices, where available. Where quoted market prices or other observable inputs are not available, the Company applies valuation techniques to estimate fair value. FASB ASC Topic 820, Fair Value Measurements and Disclosures, establishes a three-level valuation hierarchy for disclosure of fair value measurements. The categorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the measurement of fair value. The three levels of the hierarchy are defined as follows:

•Level 1 - Inputs to the valuation methodology are quoted market prices for identical assets or liabilities.

•Level 2 - Inputs to the valuation methodology are other observable inputs, including quoted market prices for similar assets or liabilities and market-corroborated inputs.

•Level 3 - Inputs to the valuation methodology are unobservable inputs based on management’s best estimate of inputs market participants would use in pricing the asset or liability at the measurement date, including assumptions about risk.

The Company's financial instruments include cash and cash equivalents, accounts receivable, accounts payable and contingent consideration. The carrying amount of cash and cash equivalents, accounts receivable, and accounts payable approximates fair value due to their immediate or short-term maturities. The recurring fair value measurements using significant unobservable inputs (Level 3) relate to contingent consideration liabilities.

The following tables provide information by level for assets and liabilities that are measured at fair value on a recurring basis:

	Fair Value Measurements using inputs considered as:						Fair Value at Nov 30, 2021
(in thousands)	Level 1		Level 2		Level 3

Contingent Liability for Acquisition Earn Outs

Some of the Company's business combinations involve the potential for the payment of future contingent consideration upon the achievement of certain product development milestones or various other performance conditions. Payment of the additional consideration is generally contingent on the acquired company reaching certain performance milestones, including attaining specified revenue levels or product development targets. Contingent consideration is recorded at the estimated fair value of the contingent payments on the acquisition date. The fair value of the contingent consideration is remeasured at the estimated fair value at each reporting period with the change in fair value recognized as income or expense within change in fair value of contingent consideration in the Consolidated Statements of Operations.

The Company measures the initial liability and remeasures the liability on a recurring basis using Level 3 inputs as defined under authoritative guidance for fair value measurements, which is determined using a discounted cash flow model applied to projected net sales, using probabilities of achieving projected net sales and projected payment dates. Projected net sales are based on internal projections and extensive analysis of the target market and the sales potential. Increases or decreases in any valuation inputs in isolation may result in a significantly lower or higher fair value measurement in the future.

The recurring Level 3 fair value measurements of the contingent consideration liabilities include the following significant unobservable inputs as of November 30, 2021:

(in thousands)	Fair Value		Valuation Technique	Unobservable Input	Range
Revenue based payments	$	16,540	Discounted cash flow	Discount rate	5%
				Probability of payment	66% - 100%
				Projected fiscal year of payment	2023 - 2025

At November 30, 2021, the amount of undiscounted future contingent consideration that the Company expects to pay as a result of all completed acquisitions is approximately $20.0 million. The milestones, including revenue projections and technical milestones associated with the contingent consideration must be reached in future periods ranging from fiscal years 2022 to 2029 in order for the associated consideration to be paid.

Leases [Abstract]

Leases

LEASES

The Company determines if an arrangement is a lease at inception of the contract. The Company has operating leases for buildings, primarily for office space, R&D, manufacturing and warehousing.

Operating lease right-of-use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. Many of the lease agreements contain renewal or termination clauses that are factored into the determination of the lease term if it is reasonably certain that these options would be exercised. The Company recognizes lease expense for these leases on a straight-line basis over the lease term.

The following table presents supplemental balance sheet information related to leases:

(in thousands)	Balance Sheet Location	Nov 30, 2021		May 31, 2021
Assets
Operating lease ROU asset	Other assets	$	8,159	$	9,382
Liabilities

Non-current operating lease liabilities	Other long-term liabilities	6,011		7,319
Total lease liabilities		$	8,484	$	9,734

The interest rate implicit in lease agreements is typically not readily determinable, and as such the Company used the incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The incremental borrowing rate is defined as the interest the Company would pay to borrow on a collateralized basis, considering factors such as length of lease term. The following table presents the weighted average remaining lease term and discount rate:

	Nov 30, 2021
Weighted average remaining term (in years)	3.68
Weighted average discount rate	3.8	%

C.R. Bard, Inc. v. AngioDynamics, Inc.

On January 11, 2012, C.R. Bard, Inc. ("Bard") filed a suit in the United States District Court of Utah claiming certain of the Company's implantable port products infringe on three U.S. patents held by Bard (US Patent Nos. 7,785,302 (“’302 Patent”), 7,959,615 (“’615 Patent”) and 7,947,022 (“’022 Patent”)). The case was stayed pending reexamination in the US Patent and Trademark Office ("USPTO"). Following the reexamination proceedings, and the parties’ related appeals to the Federal Circuit which resulted in further proceedings at the USPTO, certain claims of the ‘615 Patent were held invalid, while the remaining claims of the ‘615 Patent and the other two patents were upheld over the prior art references considered in the reexamination proceedings. Thereafter, the case was transferred from the District of Utah to the United States District Court for the District of Delaware ("District of Delaware"). A scheduling order was entered on March 23, 2021. On July 22, 2021, in

another case against a different defendant the District of Utah invalidated multiple claims of the ‘302, ‘022, and ‘615 Patents under 35 USC §101, including claims asserted against the Company. Following the Utah court’s decision, the Company filed a Motion for Judgment on the Pleadings based on collateral estoppel on August 9, 2021. Bard filed its opposition brief on September 2, 2021 and the Company filed a reply on September 9, 2021. Following a hearing on the Motion for Judgment on the Pleadings on December 21, 2021, the District of Delaware stayed the case pending the Federal Circuit's resolution of Bard's appeal from the Utah Decision. Previously, the Company had filed a Motion for Leave to Amend its Answer and Counterclaims on April 14, 2021. This motion sought to add counterclaims for infringement of U.S. Patent Nos. 9,168,365; 9,895,523; and 10,632,295, as well as a counterclaim of inequitable conduct. On November 5, 2021, the Company notified the District of Delaware that the Utah decision was certified for appeal to the Court of Appeals for the Federal Circuit. Contemporaneously, the Company withdrew its Motion for Leave to Amend its Answer and Counterclaims without prejudice to refile. Bard filed its Opening Appellate Brief in its appeal at the Federal Circuit on December 8, 2021. The Company believes these claims are without merit and intends to defend them vigorously. The Company has not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable nor reasonably estimable.

On March 10, 2015, Bard and Bard Peripheral Vascular filed suit in the District of Delaware claiming certain of the Company's implantable port products infringe on three U.S. patents held by Bard (US Patent Nos. 8,475,417, 8,545,460, 8,805,478). The case proceeded through trial which began on March 4, 2019. At the close of Bard’s case, the Court granted the Company's oral motion for judgment as a matter of law as well as its motions for summary judgment on the grounds that the asserted patents are invalid, ineligible, not infringed and not willfully infringed. On May 10, 2019, the Company filed a motion for attorney fees and non-taxable expenses under 35 USC Sec. 285. Bard appealed the judgment to the Federal Circuit and on November 10, 2020, the Federal Circuit reversed the judgment in part with respect to Section 101 (subject matter eligibility), and vacated and remanded the trial court’s invalidity and non-infringement judgments. The Company filed a combined Petition for rehearing and rehearing en banc on December 10, 2020, which was denied on January 15, 2021. The Federal Circuit issued its mandate on January 22, 2021. On March 15, 2021, the District of Delaware entered an order requiring the parties to submit status reports and denied as moot the Company’s motion for attorney’s fees and expenses. The parties agreed to schedule trial the week of May 9, 2022, and the trial has been docketed on the Court's calendar. The Company maintains its belief that Bard’s claims are without merit. The Company has not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable nor reasonably estimable.

On March 8, 2021, Bard filed suit in the District of Delaware asserting certain of the Company’s port products (including certain related infusion sets) infringe U.S. Patent Nos. 8,025,639, 9,603,992 (“’992”) and 9,603,993 (“’993”). On May 20, 2021, the Company filed a Motion to Dismiss Bard’s claims with respect to the ’992 and ’993 patents. On July 22, 2021, the Company submitted the Utah court’s decision invalidating claims of the related ‘302, ‘022, and ‘615 Patents as supplemental authority in support of its Motion to Dismiss. The parties agreed to submit supplemental briefing to address the Utah court’s decision. Bard submitted its brief on August 12, 2021, and the Company submitted its reply on September 2, 2021. On December 21, 2021, the District of Delaware stayed the case pending the Federal Circuit's resolution of Bard's appeal of the Utah decision invalidating multiple claims the ‘302, ‘022, and ‘615 patents under 35 USC §101. The Company maintains its belief that Bard’s claims of the related are without merit. The Company has not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable nor reasonably estimable.

AngioDynamics, Inc. v. C.R. Bard, Inc.

On May 30, 2017, the Company commenced an action in the United States District Court for the Northern District of New York entitled AngioDynamics, Inc. v. C.R. Bard, Inc. and Bard Access Systems, Inc. (“Bard”). In this action, the Company alleges that Bard has illegally tied the sales of its tip location systems to the sales of its PICCs. The Company alleges that this practice violates the federal antitrust laws and has had, and continues to have, an anti-competitive effect in the market for PICCs. The Company seeks both monetary damages and injunctive relief. Bard moved to dismiss on September 8, 2017. On August 6, 2018 the court denied Bard’s motion in its entirety. Bard made a motion for summary judgment which was denied in its entirety in a decision issued by the Court on May 5, 2021. Bard also raised a series of challenges targeted at one of AngioDynamics’ expert witnesses, which the Court denied in part and granted in part in decisions on May 5, 2021 and June 11, 2021. Discovery is largely complete, and trial is scheduled to commence on July 5, 2022.

Accounting Changes and Error Corrections [Abstract]

Revenue from Contracts with Customers

Revenue RecognitionUnder ASC 606, Revenue from Contracts with Customers, revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

Revenue Recognition

Revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied), which occurs at a point in time, and may be upon shipment from the Company’s manufacturing site or delivery to the customer’s named location, based on the contractual shipping terms of a contract.

In determining whether control has transferred, the Company considers if there is a present right to payment from the customer and when physical possession, legal title and risks and rewards of ownership have transferred to the customer.

The Company typically invoices customers upon satisfaction of identified performance obligations. As the Company’s standard payment terms are 30 to 90 days from invoicing, the Company does not provide any significant financing to its customers.

The Company enters into agreements to place placement and evaluation units (“units”) at customer sites, but the Company retains title to the units. During the duration of these agreements the customer has the right to use the unit at no upfront charge in connection with the customer’s ongoing purchase of disposables. These types of agreements include an embedded operating lease for the right to use the units. In these arrangements, revenue recognized for the sale of the disposables is not allocated between the disposal revenue and lease revenue due to the insignificant value of the units in relation to the total agreement value.

Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

Variable Consideration

Reserves: Revenue from product sales are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established for discounts, returns, rebates and allowances that are offered within contracts between the Company and its customers. These reserves are based on the amounts earned or to be claimed on the related sales and are classified as a contra asset.

Rebates and Allowances: The Company provides certain customers with rebates and allowances that are explicitly stated in the Company’s contracts and are recorded as a reduction of revenue in the period the related product revenue is recognized. The Company establishes reserves for such amounts, which is included in accrued expenses in the accompanying Consolidated Balance Sheets. These rebates and allowances result from performance-based offers that are primarily based on attaining contractually specified sales volumes. The Company is also required to pay administrative fees to group purchasing organizations.

Product Returns: The Company generally offers customers a limited right of return. Product returns after 30 days must be pre-approved by the Company and customers may be subject to a 20% restocking charge. To be accepted, a returned product must be unadulterated, undamaged and have at least twelve months remaining prior to its expiration date. The Company estimates the amount of its product sales that may be returned by its customers and records this estimate as a reduction of revenue in the period the related product revenue is recognized. The Company currently estimates product return liabilities using its historical product return information and considers other factors that it believes could significantly impact its expected returns, including product recalls.

Costs to Obtain or Fulfill a Customer Contract

Under ASC 606, the Company may recognize an asset for incremental costs of obtaining a contract with a customer if it expects to recover those costs. The Company’s sales incentive compensation plans qualify for capitalization since these plans are directly related to sales achieved during a period of time. However, the Company has elected the practical expedient under ASC 340-40-25-4 to expense the costs as they are incurred within selling and marketing expenses since the amortization period is less than one year.

The Company accounts for shipping and handling activities related to contracts with customers as costs to fulfill the promise to transfer the associated products. Shipping and handling costs, associated with the distribution of finished products to customers, are recorded in costs of goods sold and are recognized when the related finished product is shipped to the customer. Amounts charged to customers for shipping and handling are recorded in net sales.

As the Company has previously announced, the Company is focused on its ongoing transformation from a company with a broad portfolio of largely undifferentiated products to a more focused medical technology company that delivers unique and innovative health care solutions. The Company believes that this transformation will enable the Company to shift the portfolio from the mature, lower-growth markets where we have competed in the past by investing in technology and products that provide access to larger and faster growing markets. As such, we believe the growth in the near to mid-term will be driven by our high technology products including Auryon, Thrombectomy (which includes AngioVac, AlphaVac and thrombolytics) and NanoKnife. We will refer to these high technology products as our Med Tech business and we will refer to the remainder of the portfolio as our Med Device business.
