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 Company expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements, 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.

Net Product Revenue
The Company's products consist of medical technology products focused on restoring healthy blood flow in the body's vascular system, expanding cancer treatment options and improving quality of life for patients. The Company's products 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 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. For 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 disposable 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, product returns, rebates and allowances that are offered within contracts between the Company and its customers. 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. Discounts and product returns are based on amounts earned or to be claimed on the related sales and are classified as a contra asset. During the years ended May 31, 2025, 2024 and 2023, such product returns were not material. 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 liabilities" 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.
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 as deferred revenue in "Accrued liabilities" in the accompanying Consolidated Balance Sheets.
The following table presents changes in the Company’s receivables, contract assets and contract liabilities with customers:

Contract assets$— $— 
Contract liabilities$277 $391 
During the years ended May 31, 2025 and 2024, the Company had additions to contract liabilities of $0.2 million and $0.6 million, respectively. This was offset by $0.3 million and $0.7 million in revenue that was recognized during the years ended May 31, 2025 and 2024, respectively.
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 are recorded in net sales.
