Note 3. Revenue

We design, manufacture and service ion implantation and other processing equipment used in the fabrication of semiconductor chips and sell our products to leading semiconductor chip manufacturers worldwide. We offer a complete line of high energy, high current and medium current implanters for all application requirements. In addition, we provide extensive aftermarket lifecycle products and services, including used tools, spare parts, equipment upgrades, maintenance service and customer training. Our revenue recognition policies are set forth in Section (k) of Note 2, Summary of Significant Accounting Policies.

(a)Alternative Operational Revenue Categories used by Management

To reflect the organization of our business operations, management reviews revenue in two categories: revenue from sales of new systems and revenue arising from the sale of used systems, parts and labor to customers who own systems, which we refer to as Customer Solutions & Innovation (“CS&I”) or “aftermarket.”

Below are the revenues by categories used by management for the periods covered in this report:

(b)Economic Factors Affecting our Revenue: Geographic Breakdown of Revenue

Global economic conditions have a direct impact on our revenue. We are substantially dependent on sales of our products and services to customers outside of the United States. Adverse economic conditions, political instability, potential adverse tax consequences, regulatory changes and volatility in currency exchange rates pose a risk that our customers may reduce, postpone or cancel spending for our products and services, which would impact our revenue.

Revenue by geographic markets is determined based upon the location to which our products are shipped and where our services are performed. Revenue in our principal geographic markets is as follows:

* Adjustment to contracts with customers are assessed to determine if amounts paid by customers represent deferred revenue or liabilities payable to customers and such amounts are accordingly reclassified pursuant to our revenue recognition policy and ASC 606.

Contract liabilities are reflected as deferred revenue on the consolidated balance sheet. Contract liabilities relate to payments received or amounts invoiced in advance of completion of performance obligations under a contract. Contract liabilities are recognized as revenue upon the fulfillment of performance obligations.

As of December 31, 2025, we had deferred revenue of $108.9 million. This represents the portion of the transaction price for contracts with customers allocated to the performance obligations that remain unsatisfied or partially unsatisfied. Short-term deferred revenue of $65.5 million as of December 31, 2025 represents performance obligations that are expected to be satisfied within the next 12 months. This amount relates primarily to prepayments made prior to system

delivery as well as to installation and non-standard warranty performance obligations for system sales. Long-term deferred revenue of $43.4 million as of December 31, 2025 relates to prepayments made prior to system delivery as well as to extended warranty performance obligations that we expect to be completed in excess of the next 12 months but within the next 24 months.

The majority of our system transactions have either (1) payment terms that are 90% due upon shipment of the system and 10% due upon acceptance or (2) a pre-shipment deposit ranging from 20% to 60%, with the remainder due upon shipment, less 10% due at acceptance. Aftermarket transaction payment terms are such that payment is due either within 30 or 60 days of service provided or parts delivered.

About Revenue Disclosures

Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.

Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
