Overview

We provide comprehensive data solutions designed to empower organizations across the semiconductor and electronics ecosystems to improve the yield and quality of their products and operational efficiency for increased profitability. We derive revenues from two categories, Platform and Volume-based fees. Our offerings that contribute to Platform revenue are licenses for software (other than Cimetrix runtime licenses) and related software maintenance and technical support services; software-as-a-service (“SaaS”); engineering services; fixed fees associated with Characterization Vehicle systems; and licenses and purchase contracts for DirectScan systems. Volume-based revenue is derived from Cimetrix runtime licenses, secureWISE data, and variable/royalty fees associated with CV systems (sometimes referred to as Gainshare). Our products and services have been sold to integrated device manufacturers (“IDMs”), fabless semiconductor companies, foundries, out-sourced semiconductor assembly and test (“OSATs”), capital equipment manufacturers, and system houses.

We are headquartered in Santa Clara, California and operate worldwide with offices in Canada, China, France, Germany, Italy, Japan, Korea, and Taiwan.

Industry Trends

The confluence of Industry 4.0 (i.e. the fourth industrial revolution, or the automation and data exchange in manufacturing technologies and processes) and cloud computing (i.e. the on-demand availability of computing resources and data storage without direct active management by the user) is driving increased innovation in semiconductor and electronics manufacturing and analytics, as well as in the organization of information technology (“IT”) networks and computing at semiconductor and electronics companies across the ecosystem. First, the ubiquity of wireless connectivity and sensor technology enables any manufacturing company to augment its factories and visualize its entire production line. In parallel, the cost per terabyte of data storage has generally decreased over time. The combination of these two trends means that more data is collected and stored than ever before. Further, semiconductor companies are striving to analyze these very large data sets in real-time to make rapid decisions that measurably improve manufacturing efficiency and quality. In parallel, the traditional practice of on-site data storage, even for highly sensitive data, is changing. The ability to cost-effectively and securely store, analyze, and retrieve massive quantities of data from the cloud versus on-premise enables data to be utilized across a much broader population of users, frequently resulting in greater demands on analytics programs. The combination of these latter two trends means that cloud-based, analytics programs that effectively manage identity management, physical security, and data protection are increasingly in demand for insights and efficiencies across the organizations of these companies. We believe that all these trends will continue for the next few years, and the challenges involved in adopting Industry 4.0 and secure cloud computing will create opportunities for our combination of advanced analytics capabilities, proven and established supporting infrastructure, and professional services to configure our products to meet customers’ specialized needs.

Worldwide economic performance is uneven, and the possibility of a recession persists, leading to uneven demand. Geopolitical tensions and conflicts in various locations around the world have created volatility in the global financial markets and may have further global economic consequences, including potential disruptions of the global supply chain, heightened volatility of commodity and raw material prices, and increased fears of a global recession. Inventories of semiconductor devices remain elevated in some instances. With high inventories and soft demand for some product segments, some semiconductor fab utilization rates are also low and semiconductor capital equipment orders have been impacted for some vendors and market segments. As a result, some purchase cycles, especially for enterprise software and capital equipment and particularly with respect to larger deals, have lengthened in recent years and may continue to do so. Also, we have contractors located in the West Bank and in Israel, who are providing software development and customer technical support services. We have developed contingency plans to use alternative resources to continue serving customers, if needed. Any escalations in these areas could lead to disruptions or reductions in international trade, deter or prevent purchasing activity of customers, and negatively impact our development timelines and customer support (with respect to the conflicts in the Middle East) or China sales (with respect to U.S.-P.R.C. tensions) and financial results in general (with respect to global tensions).

The logic foundry market at the leading-edge nodes, such as 7nm, 5nm, and smaller, underwent significant change over the past few years. The leading foundry continues to dominate market share. This trend will likely continue to impact our Characterization services business on these nodes. We expect most logic foundries to invest in derivatives of older process nodes, such as 28nm and 14nm, to extract additional value as many of their customers will not move to advanced nodes due to either technological barriers or restrictive economics. Foundries that participate at leading edge nodes are expected to continue to invest in new technologies such as memory, packaging, and multi-patterned and extreme ultraviolet lithography, as well as new innovations in process control and variability management. We expect China’s investment in semiconductors to continue. Compliance with changing U.S. export restrictions limit our possible business with Chinese semiconductor manufacturers on advanced nodes. Further, trade conflict through exchange of tariffs and other retaliatory actions are expected to impact worldwide supply chains, increase prices and put downward pressure on economic activity, and could negatively affect our future sales in various geographic markets. The uncertainty caused by these regulations and the potential for additional future restrictions could negatively affect our future sales, including in but not limited to the People’s Republic of China (“P.R.C.”) market. Some customers in the P.R.C. have expressed concern about the potential for supply chain disruption due to the U.S. government’s changing export controls impacting their purchase, or in some case restricting their ability to purchase, certain U.S. goods. Based on our current assessments, we expect the near-term impact of these evolving trade restrictions on our business to be limited.

Financial Highlights

Financial highlights for the three months ended March 31, 2026, are as follows:

• Total revenues were $60.1 million, an increase of $12.4 million, or 26%, compared to the same period in 2025. Platform revenue was $50.9 million, an increase of $13.6 million, or 36%, compared to the same period in 2025. The increase in Platform revenue was driven by higher revenue from CV and DirectScan systems, the addition of revenues related to secureWISE systems, and increase in revenue from Exensio software and services. Volume-based revenue was $9.2 million, a decrease of $1.3 million, or 12%, compared to the same period in 2025, primarily due to a decrease in revenue from Gainshare, partially offset by an increase in revenue from secureWISE data usage.

• Costs of revenues increased by $4.0 million, compared to the same period in 2025, primarily due to increases in personnel-related costs, software license and maintenance costs, facilities and IT-related costs, including depreciation and amortization expense, amortization of acquired technology, and travel expense.

• Net income was $4.8 million, compared to a net loss of $3.0 million for the same period in 2025. The increase in net income was primarily attributable to (a) an increase in total revenues, (b) a decrease in acquisition-related and integration costs, and (c) a net favorable fluctuation in foreign currency exchange rates, partially offset by (i) an increase in overall costs and expenses mainly due to increases in personnel-related expenses, costs related to the operation of SecureWise, facilities and IT-related costs, including depreciation and amortization, amortization of acquired intangible assets, subcontractor fees, software license and maintenance costs, and travel expenses, (ii) an increase in interest expense from our long-term debt, (iii) a decrease in interest income, and (iv) an increase in income tax expense.

Critical Accounting Policies

Our discussion and analysis of our financial conditions, results of operations and cash flows are based on our condensed consolidated financial statements, which have been prepared in conformity with accounting principles generally accepted in the United States of America. Our preparation of these unaudited condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. The most significant estimates and assumptions relate to revenue recognition, valuation of long-lived assets including goodwill and intangible assets, stock-based compensation and the realization of deferred tax assets (“DTAs”). Actual amounts may differ from such estimates under different assumptions or conditions.

For additional information about our critical accounting policies, see Note 1, Basis of Presentation and Summary of Significant Accounting Policies, and Note 2, Revenue from Contracts with Customers to our unaudited condensed consolidated financial statements in this Quarterly Report on Form 10‑Q and Part II Item 7**,**Management’s Discussion and Analysis of Financial Condition and Results of Operation, under the heading of “Critical Accounting Estimates” in our Annual Report. There were no material changes during the three months ended March 31, 2026, to the items that we disclosed as our critical accounting policies and estimates in Part II, Item 7 of the Annual Report.

See Note 1, Basis of Presentation and Summary of Significant Accounting Policies, to our unaudited condensed consolidated financial statements in this Quarterly Report on Form 10‑Q, for a description of recent accounting pronouncements and accounting changes, including the expected dates of adoption and estimated effects, if any, on our condensed consolidated financial statements.

Results of Operations

Discussion of Financial Data for the Three Months ended March 31, 2026 and 2025

Revenues, Costs of Revenues, and Gross Margin

Beginning with our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 24, 2026, we updated our presentation of revenue categories. The change in presentation of revenues does not change our total revenues or total costs of revenues. The following table presents reclassified historical amounts to conform to the current period’s presentation (in thousands):

Platform Revenue

Platform revenue increased $13.6 million for the three months ended March 31, 2026, compared to the same period in 2025. The increase in Platform revenue was primarily driven by higher revenue from CV and DirectScan systems, the addition of revenues related to SecureWISE systems, and increase in revenue from Exensio software and services.

Volume-based Revenue

Volume-based revenue decreased $1.3 million for the three months ended March 31, 2026, compared to the same period in 2025, primarily due to decrease in revenue from Gainshare, partially offset by an increase in secureWISE data usage.

Our revenues may also fluctuate in the future due to other factors, including the semiconductor industry’s continued acceptance of our products, services and solutions, the timing of purchases by existing and new customers, cancellations by existing customers, our ability to attract new customers and penetrate new markets, supply chain challenges and further penetration of our current customer base. Fluctuations in future results may also occur if any of our significant customers renegotiate pre-existing contractual commitments, including due to adverse changes in their own business.

Costs of Revenues

Costs of revenues consist primarily of costs incurred to provide and support our services, costs recognized in connection with licensing our software, IT and facilities-related costs, and amortization of acquired technology. Service costs include material costs, hardware costs (including cost of leased assets under sales-type lease), personnel-related costs (including compensation, employee benefits, bonus and stock-based compensation expense), subcontractor costs, overhead costs, travel expenses, and allocated facilities-related costs. Software license costs consist of costs associated with third-party cloud-delivery related expenses and licensing third-party software used by us in providing services to our customers in solution engagements or sold in conjunction with our software products.

The increase in costs of revenues of $4.0 million for the three months ended March 31, 2026, compared to the same period in 2025, was primarily due to (i) a $1.8 million increase in personnel-related costs due to increased headcount and higher bonus expense, (ii) a $0.9 million increase in facilities and IT-related costs, including depreciation and amortization expense, (iii) a $0.7 million increase in software license and maintenance costs, (iv) a $0.3 million increase in amortization of acquired technology, and (v) a $0.2 million increase in travel expense.

Gross Margin

Gross margin decreased one percentage point for the three months ended March 31, 2026, to 72% compared to 73% for the same period in 2025, primarily due to decrease in revenue from Gainshare and higher costs.

Operating Expenses:

Research and Development

Research and development expenses consist primarily of personnel-related costs (including compensation, employee benefits, bonus and stock-based compensation expense), outside development services, travel expenses, third-party cloud-services related costs, IT and facilities cost allocations to support product development activities.

Research and development expenses increased $3.7 million for the three months ended March 31, 2026, compared to the same period in 2025, primarily due to (i) a $2.5 million increase in personnel-related costs due to increased headcount, higher bonus expense, and employee benefits expense, (ii) a $0.5 million increase in subcontractor fees primarily related to secureWISE systems and Exensio software, and (iii) a $0.5 million increase in facilities and IT-related costs, including depreciation and amortization expense.

We anticipate our expenses in research and development will fluctuate in absolute dollars from period to period as a result of the size and the timing of product development projects.

Selling, General, and Administrative

Selling, general, and administrative expenses consist primarily of personnel-related costs (including compensation, employee benefits, bonus, commission and stock-based compensation expense for sales, marketing, and general and administrative personnel), legal, tax and accounting services, marketing communications and trade conference-related expenses, third-party cloud-services related costs, travel, business acquisition and integration costs, IT and facilities cost allocations.

Selling, general, and administrative expenses decreased $5.9 million for the three months ended March 31, 2026, compared to the same period in 2025, primarily due to (i) a $4.3 million decrease in acquisition and integration costs related to the acquisition of SecureWise, (ii) a $1.4 million decrease in personnel-related costs mainly due to lower compensation expense allocated to selling and marketing activities, and stock-based compensation expense, and (iii) a $0.5 million decrease in facilities and IT-related costs, partially offset by a $0.2 million increase in subcontractor expenses.

We anticipate our selling, general, and administrative expenses will fluctuate in absolute dollars from period to period as a result of cost control initiatives and to support increased selling efforts in the future.

Amortization of Acquired Intangible Assets

Amortization of acquired intangible assets represents amortization expense on intangibles assets acquired from business combinations in prior years. The increase in amortization expense for the three months ended March 31, 2026, compared to the same period in 2025, was a result of the amortization of intangible assets acquired in the SecureWise acquisition in March 2025.

Interest Expense

Interest expense is from our long-term debt that was used in financing the acquisition of SecureWise in March 2025, and the related amortization of debt discount and issuance costs. Interest expense increased $0.8 million for the three months ended March 31, 2026, compared to the same period in 2025, driven by a full quarter of interest on long-term debt and the amortization of debt discount and issuance costs in the first quarter of 2026, compared to approximately one month of interest following the drawdown of long-term debt in March 2025.

Interest Income and Other, Net

Interest income and other, net, primarily consists of interest income and foreign currency transaction exchange gains and losses. Interest income and other, net decreased $0.3 million for the three months ended March 31, 2026, compared to the same period in 2025, primarily due to $0.9 million decrease in interest income from cash and cash equivalents, partially offset by a $0.6 million net favorable fluctuations in foreign currency exchange rates.

Income Tax Expense

Income tax expense increased for the three months ended March 31, 2026, compared to the same period in 2025, primarily due to the impact of enacted U.S. federal tax legislation, changes in the foreign, federal and state taxes and year-to-date recognition of worldwide pre-tax income in relation to their forecasted amounts for the full year.

Any significant change in our future effective tax rates could adversely impact our consolidated financial position, results of operations and cash flows. Our future tax rates may be adversely affected by a number of factors including increase in expenses not deductible for tax purposes, new or changing tax legislation in the United States and in foreign countries where we are subject to tax jurisdictions, the geographic composition of our pre-tax income, the amount of our pre-tax income as business activities fluctuate, our ability to use tax attributes such as research and development tax credits and net operation losses, the tax effects of employee stock activity, audit examinations with adverse outcomes, changes in accounting principles generally accepted in the United States of America and the effectiveness of our tax planning strategies.

The Organization for Economic Co-operation and Development (“OECD”) has a framework to implement a global minimum corporate tax of 15% for companies with global revenue and profits above certain thresholds (referred to as Pillar 2). Although the U.S. has not enacted legislation to implement Pillar 2, certain countries in which we operate have adopted legislation, and other countries are in the process of introducing legislation to implement Pillar 2. The OECD issued new administrative guidance on January 5, 2026, with respect to Pillar 2 which modifies key aspects of the framework for countries to enact in their own laws. Pillar 2 did not have an impact on our condensed consolidated financial statements for the first quarter of 2026 because we do not currently meet the 750 million Euro sales threshold.

Liquidity and Capital Resources

As of March 31, 2026, our working capital, defined as total current assets less total current liabilities, was $100.7 million, compared to $92.0 million as of December 31, 2025. Total cash and cash equivalents were $31.2 million as of March 31, 2026, compared to $42.2 million as of December 31, 2025. As of March 31, 2026, and December 31, 2025, cash and cash equivalents held by our foreign subsidiaries were $8.7 million and $6.7 million, respectively.

Our material cash requirements include payments for capital expenditures, principal and interest payments on our debt, cash needed to fund our operating activities, operating lease payments, and purchase obligations to support our operations. Refer to Part I, Item 1, Financial Statements, Note 4, Leases, Note 5, Debt, and Note 12, Commitments and Contingencies for details relating to our material cash requirements for debt, leasing arrangements, including future maturities of operating lease liabilities, and purchase obligations, respectively.

We believe that our existing cash resources and anticipated funds from operations will satisfy our cash requirements to fund our operating activities, capital expenditures, other obligations including repayment of long-term debt and corresponding interest for at least the next twelve months, and thereafter for the foreseeable future.

Term Loan and Revolving Credit Facility

On March 7, 2025, we entered into a Credit Agreement (the “Credit Agreement”) with the lenders who are party to the Credit Agreement and the lenders who may become a party to the Credit Agreement pursuant to the terms thereof (the “Lenders”) and Wells Fargo Bank, National Association, as administrative agent to the Lenders (the “Agent”).

The Credit Agreement provides for (a) a revolving credit facility in an aggregate principal amount of $45 million (the “Revolving Credit Facility”) and (b) a term loan facility in an aggregate principal amount of $25 million (the “Term Loan” and together with the Revolving Credit Facility, the “Credit Facilities”).

The principal of the Revolving Credit Facility is due asaballoon payment of $45.0 million in March 2030. The principal of the Term Loan is due in the amount of $0.6 million quarterly and a balloon payment of $13.1 million in March 2030.

Borrowings under the Credit Facilities will accrue interest at rates equal, at our election, to (i) the alternate base rate, which is defined as the highest of (a) the federal funds effective rate in effect from time to time plus 0.50%, (b) the prime commercial lending rate in effect from time to time, and (c) the daily simple secured overnight financing rate (“SOFR”) plus 1.00% or (ii) SOFR, plus, in each case, the applicable margin. The applicable margin for the Revolving Credit Facility borrowings bearing interest at the alternate base rate ranges from 1.00% to 1.75%, and the applicable margin for Revolving Credit Facility borrowings bearing interest based on the SOFR ranges from 2.00% to 2.75%, in each case, based on our consolidated total net leverage ratio as of the most recently ended fiscal quarter. The applicable margin for Term Loan borrowings bearing interest at the alternate base rate ranges from 1.00% to 1.75%, and the applicable margin for Term Loan borrowings bearing interest based on the SOFR ranges from 2.00% to 2.75%, in each case, based on our consolidated total net leverage ratio as of the most recently ended fiscal quarter. We will pay an annual commitment fee during the term of the Credit Agreement at a rate per annum equal to 0.50% for any undrawn portion of the Revolving Credit Facility. The Company’s weighted average annual interest rate on its outstanding debt was 5.9% for the three months ended March 31, 2026.

The Credit Agreement contains customary representations and warranties, as well as customary affirmative and negative covenants. Negative covenants include, among others, restrictions on the incurrence of debt, the incurrence of liens, the making of investments and distributions, dividends, and stock buy-backs. In addition, the Credit Agreement requires that we maintain a consolidated total net leverage ratio of not greater than 3.00 to 1.00, and a consolidated fixed charge coverage ratio of not less than 1.25 to 1.00. As of March 31, 2026, we were in compliance with the covenants contained in the Credit Agreement.

The Credit Agreement contains customary events of default. Upon the occurrence and during the continuance of an event of default, the Agent may declare the outstanding advances and all other obligations under the Credit Agreement immediately due and payable.

The obligations under the Credit Agreement are guaranteed by all present and future material domestic subsidiaries of the Company (collectively with the Company referred to herein as the “Credit Parties”), subject to customary exceptions, and are secured by the equity interests of the Credit Parties (other than the Company) and substantially all of the personal property owned by the Credit Parties, including 65% of the equity interests of certain foreign subsidiaries owned by the Credit Parties.

The Company used the amounts borrowed under the Credit Facilities to finance, in part, the purchase price paid for the acquisition of SecureWise.

First Amendment to Credit Agreement

On April 23, 2026, the Company entered into a First Amendment to Credit Agreement (the “Amendment”) with the Lenders and the Agent to amend the Credit Agreement dated as of March 7, 2025. The Amendment increases the Revolving Credit Facility to an aggregate principal amount of $75 million. The Amendment introduces leveraged-based adjustments to the annual Revolving Credit Facility commitment fee during the term of the Credit Agreement. Instead of a flat per annum rate of 0.50%, the Revolving Credit Facility commitment fee will be 0.50% when the total debt to EBITDA ratio is greater than or equal to 2.50 to 1.00, 0.35% when the total debt to EBITDA ratio is less than 2.50 to 1.00 but greater than or equal to 0.50 to 1.00 and 0.20% when the total debt to EBITDA ratio is less than 0.50 to 1.00. All other material terms of the Credit Agreement remain unchanged. Under this facility, $30.0 million is available for the issuance of letters of credit.

Repurchase of Company’s Common Stock

On April 15, 2024, the Board of Directors adopted a stock repurchase program (the “2024 Program”) to repurchase up to $40.0 million of the Company’s common stock both on the open market and in privately negotiated transactions, including through Rule 10b5-1 plans, from time to time, over the next two years from the adoption date. In 2025, the Company repurchased 12,500 shares under the 2024 Program at an average price of $19.55 per share for an aggregate total price of $0.2 million. During the three months ended March 31, 2026, the Company did not repurchase any shares under the 2024 Program. As of March 31, 2026, approximately $39.8 million remained available under the 2024 Program.

Subsequently, on April 14, 2026, the 2024 Program expired.

Also, subsequently, in May 2026, the Board Directors adopted a new stock repurchase program (the “2026 Program”) to repurchase up to $50.0 million of the Company’s common stock both on the open market and in privately negotiated transactions, including through Rule 10b5-1 plans, from time to time, over the next two years from the adoption date.

Cash Flow Data

The following table summarizes our cash flows for the periods presented:

Net Cash Flows Provided by Operating Activities

Net cash flows provided by operating activities were $1.7 million for the three months ended March 31, 2026, compared to $8.6 million for the same period in 2025. The decrease in net cash flows provided by operating activities between the periods was primarily driven by higher disbursements for operations, including payments related to vendor invoices and income taxes, lower collections from customers, and payments of interest related to bank loans, partially offset by a decrease in bonus payments under the Company’s bonus plan, and decrease in payments for business acquisition-related costs.

Net Cash Flows Used in Investing Activities

For the three months ended March 31, 2026, net cash flows used in investing activities were $10.5 million related to purchases and prepayments of property and equipment, mainly related to our DirectScan systems.

For the three months ended March 31, 2025, net cash flows used in investing activities were $123.9 million, which were primarily related to $129.7 million payments for the acquisition of SecureWise, net of cash acquired, $2.9 million purchases of short-term investments, and $8.2 million purchases and prepayments of property and equipment primarily related to our DirectScan systems, partially offset by $17.0 million proceeds from maturities and sales of short-term investments.

Net Cash Flows Provided by (Used in) Financing Activities

For the three months ended March 31, 2026, net cash flows used in financing activities were $2.1 million, which primarily consisted of $3.7 million in cash payments for taxes related to net share settlement of equity awards, and $0.6 million repayment of long-term debt, partially offset by $2.2 million proceeds from our employee stock purchase plan and exercise of stock options.

For the three months ended March 31, 2025, net cash flows provided by financing activities were $68.0 million, which primarily consisted of $69.2 million proceeds from long-term debt, net of debt discount and issuance costs, that was used in financing the acquisition of SecureWise, and $2.1 million proceeds from our employee stock purchase plan, partially offset by $3.3 million in cash payments for taxes related to net share settlement of equity awards.

Related Party Transactions

Refer to Note 13, Strategic Partnership Agreement with Advantest and Related Party Transactions, to our condensed consolidated financial statements in this Quarterly Report on Form 10‑Q, for the discussion about related party transactions between the Company and Advantest (as defined therein).

Off-Balance Sheet Agreements

As of March 31, 2026, we do not have any off-balance sheet arrangements, investments in special purpose entities or undisclosed borrowings or debt.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

The following discusses our exposure to market risk related to changes in interest rates and foreign currency exchange rates. We do not currently own any equity investments, nor do we expect to own any in the foreseeable future. This discussion contains forward-looking statements that are subject to risks and uncertainties. Actual results could vary materially as a result of a number of factors.

Interest Rate Risk. Our exposure to market risk for changes in interest rates relates primarily to our investment portfolio and long-term debt as described below.

As of March 31, 2026, we had cash and cash equivalents of $31.2 million. Cash and cash equivalents consisted of cash and highly liquid money market instruments. We would not expect our operating results or cash flows to be affected to any significant degree by the effect of a sudden change in market interest rates on our portfolio. A hypothetical increase in market interest rates of 100 basis points from the market rates in effect as of March 31, 2026, would cause the fair value of these investments to decrease by an immaterial amount which would not have significantly impacted our financial position or results of operations.

As of March 31, 2026, and periodically throughout the year, we have maintained cash balances in various operating accounts in excess of federally insured limits. We limit the amount of credit exposure to any financial institution by evaluating the creditworthiness of the financial institutions with which we invest and investing through more than one financial institution.

We are exposed to interest rate risk through our variable rate debt. As of March 31, 2026, we had $67.5 million of debt that is subject to variable interest rates that are based on the daily simple secured overnight financing rate (“SOFR”) or an alternate base rate. Refer to Note 5 – Debt for details relating to the debt. If the rates were to increase by 100 basis points from the rates in effect as of March 31, 2026, our interest expense on the variable rate debt would increase by an average of $0.4 million annually. There are inherent limitations in the sensitivity analysis presented, primarily due to the assumptions that interest rate changes would be instantaneous, while SOFR changes regularly. We do not currently hedge our interest rate risks but may determine to do so in the future. We will continue to monitor our exposure to interest rate risk.

Foreign Currency and Exchange Risk. Certain of our cash balances, receivables and payables for our international offices are denominated in the local currency, including the Euro, Yen, Chinese Yuan, New Taiwan Dollar, and Canadian Dollar. Therefore, some of our activities including a portion of our revenues and operating expenditures are subject to foreign currency risks. We also have intercompany transactions with and between certain of our subsidiaries of differing functional currencies, resulting in foreign transaction gains or losses based on our period-end exchange rates. Due to potential volatility of currency exchange rates, we cannot predict the effect of exchange fluctuations on our business. To date, we have not entered into any foreign currency exchange contracts and currently do not expect to enter into foreign currency exchange contracts for trading or speculative purposes.

Our management, with the participation of our principal executive officer and principal financial and accounting officer, evaluated the effectiveness of our “disclosure controls and procedures” as defined in Exchange Act Rules 13a‑15(e) and 15d‑15(e) as of March 31, 2026, in connection with the filing of this Quarterly Report on Form 10‑Q. Based on that evaluation as of March 31, 2026, our principal executive officer and principal financial and accounting officer concluded that our disclosure controls and procedures were effective to ensure that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and is accumulated and communicated to our management as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting during the three months ended March 31, 2026, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
