CSP INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

​

Organization and Business

CSP Inc. ("CSPi" or "CSPI" or "the Company" or "we" or "our") was incorporated in 1968 and is based in Lowell, Massachusetts. CSPi and its subsidiaries develop and market IT integration solutions, advanced security products, managed IT services, purpose built network adapters, and high-performance cluster computer systems to meet the diverse requirements of its commercial and defense customers worldwide. The Company operates in two segments, its Technology Solutions (“TS”) segment and High Performance Products (“HPP”) segment.

1. Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The accompanying interim condensed consolidated financial statements have been prepared by the Company and reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results of the interim periods presented. All adjustments were of a normal recurring nature. Certain information and footnote disclosures normally included in the annual consolidated financial statements, which are prepared in accordance with accounting principles generally accepted in the United States, have been omitted.

Accordingly, the Company believes that although the disclosures are adequate to make the information presented not misleading, the unaudited condensed consolidated financial statements should be read in conjunction with the notes contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2024. The significant accounting policies and estimates used in preparing these Condensed Consolidated Financial Statements were applied on a basis consistent with those reflected in the September 30, 2024 Consolidated Financial Statements.

​

Significant Accounting Policies

There have been no significant changes to the Company's significant accounting policies described in PART II, Item 8, Note 1 Summary of Significant Accounting Policies, of the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2024.

Accounting Pronouncement Not Yet Adopted as of March 31, 2025

In November 2023, the Financing Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires disclosure of incremental segment information on an annual and interim basis. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, on a retrospective basis. Early adoption is permitted. The Company is currently evaluating the effect of this pronouncement on its disclosures.

​

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU expands existing income tax disclosures primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The ASU is effective for all public entities for annual periods beginning after December 15, 2024, with early adoption permitted. Entities should apply the amendments on a prospective basis, but retrospective application is permitted. The Company is currently evaluating the impact this ASU will have on its disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40), which requires expanded disclosures in the notes to the financial statements about certain costs and expenses. This ASU is effective for fiscal years beginning after December 15, 2026,

and interim periods within fiscal years beginning after December 15, 2027, on a retrospective basis. Early adoption is permitted. The Company is currently evaluating the effect of this pronouncement on its disclosures.

2. Revenue

We derive revenue from the sale of integrated hardware and software, third-party service contracts, professional services, managed services, financing of hardware and software, and other services.

We recognize revenue from hardware upon transfer of control, which is at a point in time typically upon shipment when title transfers. Revenue from software is recognized at a point in time when the license is granted with the exception of the Company’s own software ARIA Advanced Threat Detection and Response (“ADR”), which is recognized evenly over time that includes the contract term.

Professional services generally include implementation, installation, and training services. Professional services are considered a series of distinct services that form one performance obligation and revenue is recognized over time as services are performed.

Revenue generated from managed services is recognized over the term of the contract. Certain managed services contracts include financing of hardware and software. Revenues from arrangements which include financing are allocated considering relative standalone selling prices of lease and non-lease components within the agreement. The lease component includes hardware, which is subject to ASC 842 Leases. The non-lease components are subject to ASC 606 Revenue from Contracts with Customers.

Other services generally include revenue generated through our royalty, extended warranty, multicomputer repair, and maintenance contracts. Royalty revenue is sales-based and recognized on the date of subsequent sale of the product, which occurs on the date of customer shipment. Revenue from extended warranty contracts is recognized ratably over the warranty period. Multicomputer repair services revenue is recognized upon control transfer when the customer takes possession of the computer at time of shipping. Revenue generated from maintenance services is recognized evenly over the term of the contract.

The right of return risk lies with the original manufacturer of the product. Managed service contracts contain the right to refund if canceled within 30 days of inception. Any products with a standard warranty are treated as a warranty obligation under ASC 460 Guarantees.

The following policies are applicable to our major categories of segment revenue transactions:

TS Segment Revenue

TS Segment revenue is derived from the sale of hardware, software, professional services, third-party service contracts, maintenance contracts, managed services, and financing of hardware and software.

Third-party service contracts are evaluated to determine whether such service revenue should be recorded as gross or net sales and whether over time or at point in time.

HPP Segment Revenue

HPP segment revenue is derived from the sale of ARIA product lines, integrated hardware and software, maintenance, and other products and services from Myricom and Multicomputer.

ARIA ADR revenue is derived from sale of software and hardware. There is one performance obligation in an ARIA ADR sale as the software and hardware are combined because they are inputs in the contract to deliver an output of

Table of Contents

threat protection. This combined performance obligation is recognized evenly over the contract term. The transaction price is fixed consideration.

ARIA Zero Trust Gateway (“AZT”) revenue contains two performance obligations: a perpetual or term software license and post-contract customer support (“PCS”). The transaction price is fixed consideration and allocated based on relative stand-alone selling price. The software license has a large majority of transaction price allocated to it. Software license revenue is recognized at a point in time, generally when the license is made available to the customer. PCS revenue is recognized ratably over the contractual period of generally one year. The PCS can be renewed and is sold on a standalone basis after the initial contract term expires.

Myricom revenue is derived from the sale of products, which are comprised of both hardware and embedded software which is essential to the products’ functionality, and PCS. PCS is considered immaterial in the context of the contract and therefore is not a separate performance obligation. Multicomputer revenue is derived from the sale of hardware, software, extended warranties, royalties, and repair services. See disaggregated revenues below by products/services and divisions/segments.

See details of timing of revenue recognition, whether CSPi acted as the principal or agent, and geography below. Geographic areas are based on which the products were shipped or services rendered.

In the TS US division, financing of goods and services is offered to certain customers. This involves amounts due reflecting sales whose payment terms exceed one year. See Note 5 Financing Receivables, net for more details. Revenue from these agreements in the three months ended March 31, 2025 was $142 thousand and CSPi acted as the agent. There was no revenue from this type of agreement in the three months ended March 31, 2024. Revenue from these agreements in the six months ended March 31, 2025 was $165 thousand and CSPi acted as the agent. Revenue from these agreements in the six months ended March 31, 2024 was $1,427 thousand, which nearly all of the revenue was with CSPi acting as the principal.

Contract Assets and Liabilities

When we have performed work but do not have an unconditional right to payment, a contract asset is recorded. When we have the right to bill a customer, accounts receivable is recorded as an unconditional right exists. Current contract assets were $0.9 million and $1.7 million as of March 31, 2025 and September 30, 2024, respectively. Current contract assets were $0.9 million as of September 30, 2023. The current portion is recorded in Other current assets on the condensed consolidated balance sheets. There were no noncurrent contract assets as of March 31, 2025 and September 30, 2024. There were no noncurrent contract assets as of September 30, 2023. The difference in the balances is due to regular timing differences between when work is performed and having an unconditional right to payment.

Contract liabilities arise when payment is received before we transfer a good or service to the customer. Current contract liabilities were $2.5 million and $2.2 million as of March 31, 2025 and September 30, 2024, respectively. Current contract liabilities were $1.9 million as of September 30, 2023. The current portion of contract liabilities is recorded in Deferred revenue and contract liabilities on the condensed consolidated balance sheets. There were no long-term contract liabilities as of March 31, 2025 and September 30, 2024, respectively. There were no long-term contract liabilities as of September 30, 2023. Revenue recognized for the six months ended March 31, 2025 that was included in contract liabilities as of September 30, 2024 was $1.0 million.

Contract Costs

Incremental costs of obtaining a contract involving customer transactions where the revenue and the related transfer of goods and services are equal to or less than a one year period, are expensed as incurred, utilizing the practical expedient in ASC 340-40-25-4. For a period greater than one year, incremental contract costs are capitalized if we expect to recover these costs. The costs are amortized over the contract term and expected renewal periods. The period of amortization is generally three years. Incremental costs are related to commissions in the TS portion of the business. Current capitalized contract costs are within the Other current assets on the condensed consolidated balance sheets as of March 31, 2025 and September 30, 2024. The portion of current capitalized costs were $23 thousand and $177 thousand as of March 31, 2025 and September 30, 2024, respectively. There are no noncurrent capitalized costs on the condensed consolidated balance sheets. The amount of incremental costs amortized for the three months ended March 31, 2025 and 2024 were $50 thousand and $121 thousand, respectively. The amount of incremental costs amortized for the six months ended March 31, 2025 and 2024 were $154 thousand and $229 thousand, respectively and is recorded in selling, general, and administrative expenses. There was no impairment related to incremental costs capitalized during the six months ended March 31, 2025 and 2024.

Projects are typically billed upon completion or at certain milestones. Products and services are typically billed when shipped or as services are being performed. Payment terms are typically 30 days to pay in full except in Europe where it could be up to 90 days. Most of our contracts are less than one year. There are certain contracts that contain a financing component. See Note 5 Financing receivables, net to the condensed consolidated financial statements for additional information. We elected to use the optional exemption to not disclose the aggregate amount of the transaction price allocated to performance obligations that have an original expected duration of one year or less. This is due to a low number of performance obligations, which are less than one year from being unsatisfied at each period end. Most of these contracts are related to product sales.

We have certain contracts that have an original term of more than one year. The royalty agreement is longer than one year, but not included in the table below as the royalties are sales-based. Managed service contracts are generally longer than one year and revenue is recognized ratably over the contract term. For these contracts the aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied or partially unsatisfied as of March 31, 2025 is set forth in the table below:

3. Earnings Per Share of Common Stock

Basic net income (loss) per common share is computed by dividing net income attributable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted net income per share

includes the dilutive effect of restricted stock, if any, calculated using the treasury stock method. For unvested restricted stock, assumed proceeds under the treasury stock method would include unamortized compensation cost.

We are required to present earnings per share (“EPS”), utilizing the two-class method because we had outstanding, non-vested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, which are considered participating securities. Net losses are not allocated to these participating securities as there are no contractual obligations that require participation in the Company’s losses.

Basic and diluted EPS share computations for the Company’s reported net income attributable to common stockholders are as follows:

Anti-dilutive securities include restricted stock, which are excluded from the diluted income per share computation. Non-vested restricted stock awards of 269 thousand shares were excluded from net loss per share for the three months ended March 31, 2025 because their inclusion would have been anti-dilutive as there was a net loss for the period.

​

4. Accounts receivable, net

The Company recognizes an allowance for losses on accounts receivable in an amount equal to the current expected credit losses. The estimation of the allowance is based on an analysis of historical loss experience, management’s assessment of current conditions and reasonable and supportable expectation of future conditions as well as an assessment of specific identifiable customer accounts considered at risk or uncollectible including reviewing the current receivables aging. This results in a general reserve and a specific reserve. The Company assesses collectability by pooling receivables where similar characteristics exist and evaluates receivables individually when specific customer balances no longer share those risk characteristics and are considered at risk or uncollectible. The expense associated with the allowance for expected credit losses is recognized in Selling, general, and administrative expenses in the Consolidated Statements of Operations.

5. Financing receivables, net

In the TS U.S. division, financing of goods and services is offered to certain customers. This involves amounts due reflecting sales whose payment terms exceed one year. This financing is separate from agreements with a leasing component, see Note 7 Leases for financing through leases. Determining whether to offer financing involves looking at the customer’s payment history, economic conditions, and capacity to pay.

The Company assigns an internal risk rating to each customer at inception, which groups customers into a portfolio based off this risk rating. A risk rating is assigned by analyzing a customer’s financial statements and the latest Fitch rating if publicly available as well as recent payment activity. The credit quality of customers is continually monitored by these items. Accounts rated low risk have the equivalent of a Fitch rating of BBB– or higher, moderate risk accounts have the equivalent of BB, and high risk accounts have the equivalent of B.

The risk characteristics of each customer are consistent with the Fitch rating or equivalent, which are defined by Fitch as the following:

'BBB' ratings indicate that expectations of default risk are currently low. The capacity for payment of financial commitments is considered adequate, but adverse business or economic conditions are more likely to impair this capacity.

’BB' ratings indicate an elevated vulnerability to default risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial flexibility exists that supports the servicing of financial commitments.

‘B’ ratings indicate that material default risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is vulnerable to deterioration in the business and economic environment.

Financing receivables, net carry an average weighted interest rate of 9.7%, which reflects the approximate interest rate consistent with a separate financing transaction with the customer at the inception of the agreement.

The Company recognizes an allowance for credit losses for financing receivables in an amount equal to the probable losses net of recoveries. A probability method for calculating credit losses is used based on historical data of defaults of Fitch ratings and length of time. Various factors are also assessed in the allowance for credit losses including internal historical data as well as macroeconomic forecast assumptions and management judgments applicable to and through the expected life of the portfolios. Macroeconomic conditions include the level of gross domestic product (“GDP”) growth and unemployment rates, which directly correlate with our historical credit losses. The expense associated with the allowance for expected credit losses is recognized in Selling, general, and administrative expenses in the Consolidated Statements of Operations.

Financing receivables whose payment terms exceed one year are placed on non-accrual status, meaning interest income stops being recorded, when the customer has a past due amount in excess of 30 days or reasonable doubt exists in collecting all interest and principal. A payment due in excess of 30 days is considered delinquent. If a payment is received for a receivable on non-accrual status the payment is first applied to interest and then principal. Recording interest income resumes once no reasonable doubt exists regarding collecting all interest and principal. There were no financing receivables placed on non-accrual status as of March 31, 2025 or September 30, 2024.

The following table presents Financing receivables, gross, including accrued interest and excluding any allowance, by credit quality indicator segregated by risk rating and year of origination as of March 31, 2025:

In April 2025, a lease agreement for a new office space for the TS U.S. division was executed, which will commence in August of 2025 and have a term for 80 months with total rent payments of around $1.2 million. The division’s office in Deerfield Beach will move to Boca Raton, Florida.

​

8. Accounts payable and Other noncurrent liabilities

The TS US division enters into certain multi-year agreements with vendors when also entering into some of the multi-year financing contracts the Company enters into with customers. See Note 5 Financing receivables, net for further information related to the multi-year agreements with customers.

There was not an interest rate stated in the agreements and therefore interest was imputed under ASC 835 Interest as the payments in the exchange represented two elements: principal and interest. The average imputed interest rate for the agreements was determined to be 8.4% as of March 31, 2025. The rate was determined primarily based on the rate the Company could obtain by financing from other sources at the date of the transaction.

Interest expense related to these agreements for the three months ended March 31, 2025 and 2024 was $75 thousand and $35 thousand, respectively. Interest expense related to these agreements for the six months ended March 31, 2025 and 2024 was $150 thousand and $88 thousand, respectively.

The amounts owed for these agreements are in Accounts payable and accrued expenses and Other noncurrent liabilities because they are owed to vendors rather than banks or financial institutions for borrowings. See Note 9 Line of Credit for amounts due to financial institutions for borrowings.

​

Below are details of the agreements with the vendors that contain imputed interest:

The TS segment has many vendors it transacts with and does not have any specific agreement with this vendor that it must purchase certain products from the vendor. Management believes other suppliers could provide similar products on comparable terms.

​

9. Line of Credit

As of March 31, 2025 and September 30, 2024, the Company maintained an inventory line of credit with a borrowing capacity of $15.0 million. It may be used by the TS and HPP segments in the US to purchase inventory from approved vendors with payment terms which exceed those offered by the vendors. No interest accrues under the inventory line of credit when advances are paid within terms, however, late payments are subject to an interest charge of Prime plus 5%. The credit agreement for the inventory line of credit contains financial covenants which require the Company to maintain the following TS segment-specific financial ratios: (1) a minimum current ratio of 1.2, (2) tangible net worth of no less than $4.0 million, and (3) a maximum ratio of total liabilities to total net worth of less than 5.0:1. As of March 31, 2025 and September 30, 2024, Company borrowings, all from the TS segment, under the inventory line of credit were $0.4 million and $4.2 million, respectively, and the Company was in compliance with all financial covenants. As of March 31, 2025 and September 30, 2024, this line of credit also includes availability of a limited cash withdrawal of up to $1.0 million. As of March 31, 2025 and September 30, 2024 there were no cash withdrawals outstanding.

​

10. Pension and Retirement Plans

The Company’s operations have defined benefit and defined contribution plans in the U.K. and in the U.S. In the U.K., the Company provides defined benefit pension plans and defined contribution plans for some of its employees. In the U.S., the Company provides benefits through supplemental retirement plans to certain former employees. The U.S. supplemental retirement plans have life insurance policies which are not plan assets but were purchased by the Company as a vehicle to fund the costs of the plan. The Company also provides for officer death benefits through post-retirement plans to certain current officers of the Company in the U.S. All the Company’s defined benefit plans are closed to newly hired employees and have been since September 2009.

The Company funds its pension plans in amounts sufficient to meet the requirements set forth in applicable employee benefits laws and local tax laws. Liabilities for amounts in excess of these funding levels are accrued and reported in the condensed consolidated balance sheets.

The Company’s pension plan in the U.K. is the only pension plan with plan assets. In October 2024 the company contributed approximately 0.6 million Great British Pounds to the U.K. pension plan and all of the plan assets were converted to cash. Also in October 2024, in connection with the planned termination of our defined benefit pension plan in the U.K., we paid 8.5 million Great British Pounds to enter into a buy-in contract. This payment is subject to adjustment as a result of subsequent data cleansing activities. Under the terms of this buy-in contract, the insurer is liable to pay the benefits of the plan, but the Company still retains full legal responsibility to pay the benefits to members using the insurance payments. In accordance with US GAAP, specifically ASC 715-30 Defined Benefit Plans – Pension, the buy-in contract does not qualify as a significant event and therefore remeasurement is not required. The buy-in contract will be treated as a plan asset. When the buy-in contract transitions to a buy-out contract the Company will no longer have legal responsibility to pay the benefits to the members. This transition is a significant event and the pension assets and liabilities will be remeasured at this time. If the transition does not occur before September 30, 2025, the pension assets and liabilities will be remeasured as of this date in accordance with our Pension and Retirement Plans accounting policy.

​

*This fair value is as of December 31, 2025 and is based on the latest information available. The buy-in contract is valued on an insurer pricing basis, which reflects the purchase price adjusted for changes in discount rates and other actuarial assumptions, which approximates fair value. Due to this, the buy-in contract is classified as a Level 3. The fair value of the buy-in contract can vary significantly based on the 20-year U.K. gilt yield, which was around 4.5% as of September 30, 2024 and 5.0% as of December 31, 2024 leading to a decrease in fair value. Additionally, the profit realized by the insurance company is not considered in the fair value and a decrease will occur from payments made to the pensioners.

​

11. Income Taxes

The Company recorded an income tax benefit of $683 thousand and income tax expense of $135 thousand for the three months ended March 31, 2025 and 2024, respectively, and an income tax benefit of $798 thousand and income tax expense of $148 thousand for the six months ended March 31, 2025 and 2024, respectively. The income tax benefit for the three and six months ended March 31, 2025 was primarily driven by the impact of tax credits that we expect to be able to utilize against federal and state taxes and the excess tax benefits on restricted stock awards vested during the period. The income tax expense for the three and six months ended March 31, 2024 was primarily driven by income earned in the United States.

13. Fair Value of Financial Assets and Liabilities

Under the fair value standards fair value is based on the exit price and defined as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement should reflect all the assumptions that market participants would use in pricing an asset or liability. A fair value hierarchy is established in the authoritative guidance outlined in three levels ranking from Level 1 to Level 3 with Level 1 being the highest priority.

​

Level 1: observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets

​

Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly

​

Level 3: unobservable inputs (e.g., a reporting entity’s or other entity’s own data)

​

The Company had no assets or liabilities measured at fair value on a recurring basis (except our pension plan assets and whole life insurance policies, see Note 10 Pension and Retirement Plans for pension plan assets) or non-recurring basis as of March 31, 2025 or September 30, 2024.

​

To estimate fair value of the financial instruments below, quoted market prices are used when available and classified within Level 1. If this data is not available, we use observable market-based inputs to estimate fair value, which are classified within Level 2. If the preceding information is unavailable, we use internally generated data to estimate fair value which is classified within Level 3.

​

Line of credit

The fair value of our line of credit is based on borrowing rates currently available to a market participant for loans with similar terms or maturity. The carrying amount of our outstanding revolving line of credit approximates fair value because the base interest rate charged varies with market conditions and the credit spread is commensurate with current market spreads for issuers of similar risk. No interest accrues under the inventory line of credit when advances are paid within terms.

Operating (loss) income consists of sales less cost of sales, engineering and development expenses, and selling, general and administrative expenses but is not affected by either other income (expense) or by income tax expense (benefit). Non-operating expenses/income consists principally of interest income from transactions with payment terms exceeding one year (see Note 5 Financing receivables, net for details) and interest income from money market accounts, and interest expense primarily from multi-year agreements with vendors (see Note 8 Accounts payable and other noncurrent liabilities). All intercompany transactions have been eliminated.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Forward-Looking Statements

The discussion below contains certain forward-looking statements including, but not limited to, among others, statements concerning future revenues and future business plans. Forward-looking statements include statements in which we use words such as “expect”, “believe”, “anticipate”, “intend”, “project”, “estimate”, “should”, “could”, “may”, “plan”, “potential”, “predict”, “project”, “will”, “would” and similar expressions. Although we believe the expectations reflected in such forward-looking statements are based on reasonable assumptions, the forward-looking statements are subject to significant risks and uncertainties, and thus we cannot assure you that these expectations will prove to have been correct, and actual results may vary from those contained in such forward-looking statements. We discuss many of these risks and uncertainties in Item 1A under the heading “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024. An additional risk factor can be found within this Form 10-Q under Item 1A under the heading “Risk Factors.” Factors that may cause such variances include, but are not limited to, our dependence on a small number of customers for a significant portion of our revenue, intense competition in the market segments in which we operate, changes in the U.S. Tax laws, the impact of the Ukrainian-Russian military and Israeli-Hamas conflict on global trade and

financial markets, and the impact of pandemics on our business, tariffs, results of operations and financial condition. Given these uncertainties, you should not place undue reliance on these forward-looking statements. Also, forward-looking statements represent our estimates and assumptions only as of the date of this document. Except as required by law, we do not undertake any obligation to publicly update or revise any forward-looking statements contained in this report, whether as a result of new information, future events or otherwise. This management’s discussion and analysis of financial condition and results of operations should be read in conjunction with our financial statements and the related notes included elsewhere in this filing and in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. On an ongoing basis, we evaluate our estimates, including those related to the allowance for credit losses for accounts receivable and financing receivables, inventory valuation, impairment assessment of intangibles, income taxes, deferred compensation and retirement plans, as well as estimated selling prices used for revenue recognition and contingencies. We base our estimates on historical performance and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. A description of our critical accounting policies is contained in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024 in the “Critical Accounting Policies” section contained in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations. Management believes there have been no significant changes for the three months ended March 31, 2025 to the items that we disclosed as our critical accounting estimates in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of our Annual Report on Form 10-K for the fiscal year ended September 30, 2024.

Recent trends affecting our financial performance

As of March 31, 2025, the Russian/Ukrainian military conflict and the Israeli-Hamas conflict have not had a direct significant impact on revenue as we do not have any significant recurring customers in either region. However, we do have customers and suppliers in surrounding regions which may be affected and further escalation of both conflicts and geopolitical tensions related to such conflicts could adversely affect our business, financial condition and results of operations, by among other things, cyberattacks, supply disruptions, lower consumer demand, and changes to foreign exchange rates and financial markets. It is not possible at this time to predict the size of the impact or consequences of the conflicts on the Company and our customers or suppliers.

Sales

Our sales decreased by approximately $0.6 million, or 4%, to $13.1 million for the three months ended March 31, 2025 compared to $13.7 million for the same prior year period. The decrease in sales is the result of a decrease of $1.9 million in our HPP segment, partially offset by a $1.3 million increase in our TS segment.

TS segment sales change was as follows for the three months ended March 31, 2025 and 2024:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | March 31, | ​ | Increase (decrease) |

Total | ​ | $ | 12,500 | ​ | $ | 11,204 | ​ | $ | 1,296 | ​ | 12 | %

​

The increase in TS segment product sales of $1.9 million is due to increased sales to several existing major customers in the US division of $1.5 million and the UK division of $0.4 million. Service sales for the three months ended March 31, 2025 decreased $0.6 million from the same prior year period, which was attributable to the US division. The decrease in service sales included decreased third-party maintenance sales of $0.9 million, partially offset by increased managed services sales of $0.2 million and increased internal and third-party services of $0.1 million.

HPP segment sales change was as follows for the three months ended March 31, 2025 and 2024:

​

The HPP product sales decreased $1.8 million for the three months ended March 31, 2025 compared to the same prior year period as a result of one decreased sale of ARIA Zero Trust Gateway to one major customer of $2.0 million in the prior year not recurring in the current year period, partially offset by increased ARIA Zero Trust Gateway sales to new customers of $0.2 million. The HPP service sales decreased $0.1 million due to decreased royalties of $0.2 million, partially offset by $0.1 million increased ARIA AZT customer support revenue.

Totals | ​ | $ | 13,147 |  | 100 | % | $ | 13,706 |  | 100 | % | $ | (559) | ​ | (4) | %

​

The $1.2 million decrease in sales to the Americas was primarily the result of a $2.0 million decrease in the HPP segment, partially offset by an increase in the TS segment’s US division of $0.8 million. The $0.5 million increase in sales to Europe was primarily the result of increased sales by our TS segment’s UK division of $0.4 million and the US division of $0.1 million. The sales to APAC and Africa increased $0.1 million for the three months ended March 31, 2025 compared to the same prior year period due to an increase in the HPP segment expanding its ARIA AZT sales in the region.

Gross Margins

Our gross margin ("GM") decreased $2.3 million for the three months ended March 31, 2025 as compared to the same prior year period. The GM as a percentage of sales decreased to 32% for the three months ended March 31, 2025 compared to the same prior year period of 47%.

​

The overall TS segment GM as a percentage of sales decreased to 31% for the three month period ended March 31, 2025 compared to 39% for the same prior year period. Product GM as a percentage of revenue decreased 1% due to a different product mix without any significant changes from the prior year period. The service GM as a percentage of revenue decreased 10% from the prior year due to decreased third-party maintenance sales, which are recorded “net” meaning the revenue, net of the associated cost, is recorded in the Services revenue financial statement line item causing an increase in GM as a percentage of sales.

​

The overall HPP segment GM as a percentage of sales decreased to 57% for the three months ended March 31, 2025 from 86% for the three months ended March 31, 2024. The 27% decrease in product GM as a percentage of product revenue for the three months ended March 31, 2025 compared to the same prior year period is due to one large ARIA Zero Trust Gateway order in the prior year period, which did not recur in the current period. The large ARIA Zero Trust Gateway order in the prior year was nearly all GM. The service GM as a percentage of services revenue from the same prior year period decreased 19% to 53% for the three months ended March 31, 2025 compared to 72% for the three months ended March 31, 2024 due to decreased royalty sales, which are nearly all GM.

Engineering and Development Expenses

The engineering and development expenses incurred by our HPP segment remained relatively flat for the three months ended March 31, 2025 compared to the prior year period without any significant changes in the expense mix. The current period expenses were primarily for product engineering expenses incurred in connection with the continued development of the ARIA Zero Trust Gateway cyber security products.

Selling, General and Administrative Expenses

​

SG&A expenses decreased $0.1 million to $4.4 million for the three months ended March 31, 2025 compared to the same prior year period. The $0.1 million decrease in TS segment SG&A expenses compared to the same prior year period is primarily the result of decreased variable compensation. The HPP segment SG&A expenses remained relatively flat at $1.2 million the three months ended March 31, 2025 as compared to the prior year period due to increased salaries of $0.1 million, which was offset by decreased commissions of $0.1 million.

Total other income, net | ​ | $ | 203 | ​ | $ | 489 | ​ | $ | (286)

​

Total other income, net for the three months ended March 31, 2025 was $0.2 million compared to $0.5 million for the three months ended March 31, 2024.

The $0.2 million decreased foreign exchange loss for the three months ended March 31, 2025 was primarily due to the US Dollar weakening relative to the British Pound compared to the same prior year period. In consolidation, US dollars are remeasured into the functional currency, British Pounds, of our UK subsidiary. This non-cash remeasurement is included in the foreign exchange gain (loss) in the Consolidated Statements of Operations. The foreign exchange loss was primarily from the US Dollar bank account in our TS UK division.

Interest income decreased $64 thousand for the three months ended March 31, 2025 compared to the same prior year period primarily due to decreased interest income from agreements that have payment terms in excess of one year (see Note 5 Financing receivables, net in Item 1 to this Quarterly Report on Form 10-Q for details). Although new agreements with higher interest rates have been entered into during fiscal 2024 and 2025, this is more than offset by lower interest income recognized from a larger number of prior agreements because interest income decreases from each agreement as time elapses due to principal payments being received. All of these agreements are in the TS-US division.

The interest expense increase of $31 thousand for the three months ended March 31, 2025 compared to the same prior year period was related to the TS US division entering into additional multi-year vendor contracts related to sales agreements that have payment terms in excess of one year during fiscal years 2024 and 2025. Interest expense increased while interest income decreased because many of the Company’s financing sales prior to fiscal year 2024 did not have vendor financing, but in fiscal years 2024 and 2025 vendor financing became more prevalent.

Income Taxes

The Company recorded an income tax benefit of $683 thousand and income tax expense of $135 thousand for the three months ended March 31, 2025 and 2024, respectively. The income tax benefit for the three months ended March 31, 2025 was primarily driven by the impact of tax credits that we expect to be able to utilize against federal and state taxes and the excess tax benefits on restricted stock awards vested during the period. The income tax expense for the three months ended March 31, 2024 was primarily driven by income earned in the United States.

Overview of the six months ended March 31, 2025

Our sales decreased by $0.3 million, or 1%, to $28.8 million for the six months ended March 31, 2025 as compared to $29.1 million for the six months ended March 31, 2024. The decrease in sales is the result of a decrease of approximately $2.2 million in our HPP segment, partially offset by an increase of $1.9 million in the TS segment. Our gross margin percentage decreased 6% to 30% of sales for the six months ended March 31, 2025 compared to 36% for the six months ended March 31, 2024.

Sales

Our sales decreased by approximately $0.3 million, or 1%, to $28.8 million for the six months ended March 31, 2025 as compared to $29.1 million for the six months ended March 31, 2024. The decrease in sales is the result of a decrease of approximately $2.2 million in our HPP segment, partially offset by an increase of $1.9 million in the TS segment.

TS segment sales change was as follows for the six months ended March 31, 2025 and 2024:

Total | ​ | $ | 27,740 | ​ | $ | 25,867 | ​ | $ | 1,873 | ​ | 7 | %

​

The increase in TS segment product sales of $1.9 million during the period as compared to the prior year period is attributable to increased sales of $1.7 million to several existing major customers in the US division combined with an increase in sales of $0.2 million in the UK division to existing customers. Service sales for the six months ended March 31, 2025 remained relatively flat from the prior year period with changes in the mix of revenue including an increase of $0.2 million from internal and third-party services and an increase in managed services of $0.1 million, offset by a decrease in third-party services of $0.3 million. All of these service sales changes occurred in the US division.

​

The HPP product sales decreased by $2.2 million for the six months ended March 31, 2025 as compared to the prior year period primarily as a result of one large ARIA AZT order of $2.0 million which occurred in the prior year period

and did not recur in the current year combined with a $0.5 million decrease in Myricom sales, which was partially offset by increased ARIA AZT revenue to new customers of $0.3 million. The HPP service sales remained flat for the six months ended March 31, 2025 compared to the prior year period with changes in the mix of revenue including increased ARIA AZT customer support revenue of $0.2 million, which was offset by decreased revenue from royalties on high-speed processing boards related to the E2D program.

Our sales by geographic area, which are based on the customer location to which the products were shipped or services rendered, were as follows for the six months ended March 31, 2025 and 2024:

Totals | ​ | $ | 28,817 |  | 100 | % | $ | 29,081 |  | 100 | % | $ | (264) | ​ | (1) | %

​

The $0.3 million decrease in sales to the Americas was the result of a decrease in the HPP segment of $2.3 million, which was partially offset by the TS segment’s US division increase of $2.0 million. The sales to Europe increased $0.2 million due to increased sales in the TS US division of $0.1 million and the TS UK division of $0.1 million. The sales to APAC and Africa decreased $0.2 million as a result of decreased sales in the TS segment’s US division of $0.3 million, partially offset by increased sales in the HPP segment of $0.1 million.

Gross Margins

Our gross margin ("GM") decreased $1.8 million for the six months ended March 31, 2025 compared to the same prior year period. The GM as a percentage of total sales decreased to 30% for the six months ended March 31, 2025 as compared to the same prior year period of 36%.

​

The overall TS segment GM as a percentage of total sales decreased to 30% for the six month period ended March 31, 2025 compared to 31% from the prior year period. Product GM as a percentage of revenue for the six months ended March 31, 2025 decreased 1% from the prior year period due to product mix. Service GM as a percentage of total sales decreased to 57% for the six months ended March 31, 2025 compared to 58% from the prior year period. This was primarily due to decreased third-party maintenance sales, which are recorded “net” meaning the revenue, net of the associated cost, is recorded in the Services revenue financial statement line item causing an increase in GM as a percentage of sales.

​

The overall HPP segment GM as a percentage of sales decreased to 54% for the six months ended March 31, 2025 from 78% for the six months ended March 31, 2024. The 18% decrease in product GM as a percentage of product revenue compared to the same prior year period was primarily attributed to one large ARIA Zero Trust Gateway order in the prior year period, which was nearly all GM and did not recur in the current period. The 7% decrease in service GM as a percentage of service revenue for the six months ended March 31, 2025 compared to the same prior year period was due to decreased royalty sales, which are nearly all GM, partially offset by more AZT customer support GM.

Engineering and Development Expenses

The engineering and development expenses incurred by our HPP segment increased to $1.5 million for the six months ended March 31, 2025 compared to the same prior year period of $1.4 million due to increased consulting as the quantity of sales opportunities increased. The current period expenses were primarily for product engineering expenses incurred in connection with the continued development of the ARIA Zero Trust Gateway cyber security products.

Selling, General and Administrative Expenses

​

SG&A expenses increased $0.3 million for the six months ended March 31, 2025 compared to the same prior year period. The $0.2 million increase in TS segment SG&A expenses compared to the same prior year period is primarily the result of increased stock compensation expense. The HPP segment SG&A expenses increased $0.1 million for the six months ended March 31, 2025 as compared to the prior year period primarily due to increased stock compensation expense.

​

Total other income, net for the six months ended March 31, 2025 increased $0.1 million to income of $0.9 million compared to income of $0.8 million in the same prior year period.

The $0.3 million increased foreign exchange gain for the six months ended March 31, 2025 was due to the US Dollar strengthening relative to the British Pound compared to the same prior year period. In consolidation, US dollars are remeasured into the functional currency, British Pounds, of our UK subsidiary. This non-cash remeasurement is included in the Foreign exchange gain (loss) in the Consolidated Statements of Operations. The foreign exchange gain in the current period was primarily from the US Dollar bank account in our TS UK division.

Interest income decreased $71 thousand for the six months ended March 31, 2025 compared to the same prior year period primarily due to decreased interest income from agreements that have payment terms in excess of one year (see Note 5 Financing receivables, net in Item 1 to this Quarterly Report on Form 10-Q for details). Although new agreements with higher interest rates have been entered into during fiscal years 2024 and 2025, this is more than offset by lower interest income recognized from a larger number of prior agreements because interest income decreases from each agreement as time elapses due to principal payments being received. All of these agreements are in the TS-US division.

The interest expense increase of $59 thousand for the three months ended March 31, 2025 compared to the same prior year period was primarily related to the TS US division entering into additional multi-year vendor contracts related to sales agreements in fiscal year 2025 that have payment terms in excess of one year. Interest expense increased while interest income decreased because many of the Company’s financing sales prior to fiscal year 2024 did not have vendor financing, but in fiscal years 2024 and 2025 vendor financing became more prevalent.

Income Taxes

The Company recorded an income tax benefit of $798 thousand and income tax expense of $148 thousand for the six months ended March 31, 2025 and 2024, respectively. The income tax benefit for the six months ended March 31, 2025 was primarily driven by the impact of tax credits that we expect to be able to utilize against federal and state taxes and the excess tax benefits on restricted stock awards vested during the period. The income tax expense for the six months ended March 31, 2024 was primarily driven by income earned in the United States.

​

Liquidity and Capital Resources

Our primary source of liquidity is our cash and cash equivalents and our line of credit.

Cash and cash equivalents decreased by $1.1 million to $29.5 million as of March 31, 2025 from $30.6 million as of September 30, 2024.

​

Operating Activities

Cash provided by operating activities was $3.7 million for the six months ended March 31, 2025 compared to $3.3 million provided by operating activities in the prior year. The significant changes from the prior period include increased collections of Accounts receivable of $0.7 million, decreased payments in Accounts payable and accrued expenses of $1.2 million, partially offset by decreased collections of Financing receivables of $0.7 million and a decreased inventory change of $0.8 million. The remaining differences are primarily related to timing differences in operating assets and liabilities. Inventory fluctuations are dependent on when orders are received and shipped. Accounts payable and accrued expenses fluctuations are dependent on when vendor invoices are received as well as the related timing of the payments.

​

Investing Activities

Cash used in investing activities was $0.1 million for the six months ended March 31, 2025 compared to $0.2 million used in investing activities for the prior year period. The decrease in cash used from the prior year is due to decreased purchases of property, equipment, and improvements.

Financing Activities

Cash used in financing activities increased approximately $3.4 million from the prior year to $4.6 million for the six months ended March 31, 2025 compared to $1.2 million for the prior year period. The increase from the prior year was primarily due to increased net borrowing on our line-of-credit of approximately $3.2 million from the prior year, increased cash dividend payments of $0.2 million, repurchases of common stock of $0.4 million, partially offset by a decrease of a note payable of $0.4 million.

Other Liquidity and Capital Resources Items

Our cash held by our foreign subsidiary in the United Kingdom totaled approximately $4.6 million as of March 31, 2025 and consisted of 0.3 million Euros, 0.5 million British Pounds, and 3.6 million US Dollars. This cash is included in our total cash and cash equivalents reported on the Condensed Consolidated Balance Sheets.

As of March 31, 2025 and September 30, 2024, the Company maintained a line of credit with a capacity of up to $15.0 million for inventory accessible to both the HPP and TS segments. This line of credit also includes availability of a limited cash withdrawal of up to $1.0 million. An amount of $14.6 million and $10.8 million were available as of March 31, 2025 and September 30, 2024, respectively. As of March 31, 2025 and September 30, 2024 there were no cash withdrawals outstanding. For further discussion of the Company’s line of credit, including its financial covenants, see Item 1, Note 9 Line of Credit.

development or enhancement of products, take advantage of future opportunities, respond to competition, retain key employees, or continue to effectively operate our business.

Based on our current plans and business conditions, management believes that the Company’s available cash and cash equivalents, the cash generated from operations, and availability on our line of credit will be sufficient to provide for the Company’s working capital and capital expenditure requirements for at least 12 months from the date of this filing.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2025 based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations (“COSO”) of the Treadway Commission (“2013 Framework”). Our Chief Executive Officer, our Chief Financial Officer and other members of our senior management team supervised and participated in this evaluation. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2025, the Company’s Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were not effective, due to the fact that we are not yet able to conclude that the material weaknesses described in this Item 4 have been remediated by the changes we made in response to these material weaknesses.

As previously disclosed in Item 9A of our Annual Report on Form 10-K for the period ended September 30, 2024, our management identified two material weaknesses as of such date. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be able to be prevented or detected on a timely basis.

Material weakness 1 – Corporate credit cards

In August 2024 during its fiscal year 2024 third quarter review the Company identified certain control deficiencies related to its business expense reimbursement and selected purchases policy and application of a legacy credit card program for Company credit cards. The control deficiencies arose out of a lack of adequate review and incomplete supporting documentation related to certain business expenses including those for reimbursement for Company credit card charges from a C level Company executive as well as an undocumented compensation agreement with regards to the use of credit card points which resulted in undisclosed compensation. The Audit Committee engaged a third party to investigate and analyze certain transactions made on the corporate credit card and it was not led by management. As of September 30, 2024, the C-level executive returned to the Company approximately $20,000 in aggregate related to the portion of the undisclosed compensation in excess of the intended compensation agreement. There were no subsequent amounts of undisclosed compensation returned to the company.

In response to these control deficiencies, the Company performed additional analysis and reconciliation around all the credit card activity, including reimbursement, purchases and review of the credit card use policies, assessed various alternatives to remediate this material weakness and implemented changes to our internal controls including implementation of additional review and confirmation process by designated employees and the termination of the legacy benefit program identified above.

39

Table of Contents

During the preparation of our annual financial statements, we determined that the controls over the credit card process were not operating effectively, and the resulting control gap amounted to a material weakness in our controls over financial reporting. As a result, we concluded that the Company’s internal control over financial reporting was not effective as of September 30, 2024. The COSO principles of Exercises oversight responsibility and develops control activities were not properly followed in our internal controls. Although we have implemented changes to our internal controls over financial reporting as described herein, as of March 31, 2025 we cannot conclude that the material weaknesses has been remediated.

Material weakness 2 – Income taxes

Management identified another material weakness in our internal controls over financial reporting for income taxes relating to current/non-current taxes payable, certain deferred tax assets and liabilities, and current and deferred tax expenses. We use a third-party provider to prepare our tax provision and related disclosures on a quarterly basis. The company reviews the provision and disclosures. We believe the material weakness occurred due to a lack of competency of the third-party provider and management needs to perform a more comprehensive review with the third-party preparer. Although we have implemented changes to our internal controls over financial reporting as described herein, as of March 31, 2025 we cannot conclude that the material weaknesses has been remediated.

​

Remediation of Material Weaknesses

We are committed to maintaining a strong internal control environment and implementing measures designed to help ensure that the material weaknesses are remediated as soon as possible. We believe we have made progress towards remediation and continue to implement our remediation plan for the material weakness, which includes the following steps.

Material weakness 1 – Corporate credit cards

| ● | All points earned on the Company credit cards will accrue only to the benefit of the Company.

| ● | The Company updated its Credit Card purchase and Reimbursement Policy and has taken steps to ensure the Expense Policy is followed with documentation and proper approvals.

| ● | In fiscal year 2025, internal audit will test a reasonable number of selections from all corporate credit card expenses monthly and report findings directly to the Company’s CFO. If there is an exception, this will be reported to the Audit Committee

| ● | Quarterly a summary report of Credit card internal audit results will be reported to the Audit Committee.

Material weakness 2 – Income taxes

| ● | Hired a new accounting firm with global expertise as our new third-party tax provider to prepare tax provisions and corporate income tax returns. We intend to use this firm to assist with enhancing internal controls over financial reporting for income taxes and developing and implementing a remediation plan.

| ● | Hold quarterly meetings with our new third-party tax provider to discuss changes in tax law, key aspects of our quarterly/annual provisions and required updates to provisions, deciding a course of action and documenting such actions, review and approval of the tax data by senior members of our finance team and final discussion, review and approval of the third-party provider prepared provisions and returns.

| ● | Provide income tax accounting training to those involved in the review of the tax data from our third-party tax provider.

40

Table of Contents

We will consider the material weaknesses remediated after the applicable controls operate for a sufficient period of time, and management has concluded, through testing, that the controls are operating effectively.

The process of designing and implementing an effective accounting and financial reporting system is a continuous effort that requires us to anticipate and react to changes in our business and the economic and regulatory environments and to expend significant resources to maintain an accounting and financial reporting system that is adequate to satisfy our reporting obligations. As we continue to evaluate and take actions to improve our internal control over financial reporting, we may determine to take additional actions to address control deficiencies or determine to modify certain of the remediation measures described above.

Changes in Internal Control over Financial Reporting

During the six months ended March 31, 2025, with the exception of the changes described above within this Item 4 there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1A. Risk factors

Except as set forth below, there have been no material changes to the risk factors set forth in Item 1A under the heading “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024.

Significant political, trade, regulatory developments, and other circumstances beyond our control, could have a material adverse effect on our financial condition or results of operations.

​

Significant political, trade, or regulatory developments in the jurisdictions in which we sell or purchase our products, including country of origin of such products, are difficult to predict and may create periods of volatility in such markets which may have a material adverse effect on us. Recent changes in U.S. federal policy that affect the geopolitical landscape could give rise to circumstances outside our control that could have negative impacts on our business operations. Beginning in the second quarter of 2025, new U.S. Tariffs were announced, including additional tariffs on imports from China, India, Japan, South Korea, Taiwan, Vietnam and the EU, among others. In response, several countries have imposed, or threatened to impose, reciprocal tariffs on imports from the U.S. and other retaliatory measures. Various modifications and delays to the U.S. Tariffs have been announced and further changes are expected to be made in the future, which may include additional sector-based tariffs or other measures. For example, the U.S. Department of Commerce has initiated an investigation under Section 232 of the Trade Expansion Act of 1962, as amended, into, among other things, imports of semiconductors, semiconductor manufacturing equipment, and their derivative products, including downstream products that contain semiconductors. These tariffs do not currently include software, services, intangibles, and other digital services; however, we cannot predict future trade policy or tariffs, including the impact or timing thereof, or whether such services will be subject to any form of tariffs or other restrictions in the future. The ultimate impact remains uncertain and will depend on several factors, including whether additional or incremental U.S. Tariffs or other measures are announced or imposed, to what extent other countries implement tariffs or other retaliatory measures in response, and the overall magnitude and duration of these measures. If disputes and conflicts further escalate, actions by governments in response could be significantly more severe and restrictive. Any of the foregoing could materially adversely affect the Company’s business, results of operations, financial condition and stock price.
