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 New Significant Accounting Policy

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, 2023.

Presentation – sales whose payment terms exceed one year

Effective in fiscal year 2024 sales whose payment terms exceed one year is now presented as “Financing receivables, net of allowances” on the Consolidated Balance Sheets rather than being combined with Accounts receivable, net of allowances. The financial statement line item Long-term receivable is now labeled as “Financing receivables due after one year, net of allowances.” These changes are reflected retrospectively as of September 30, 2023. This change was made to provide more detail on the balance sheet related to these receivables and align with our notes to the unaudited condensed consolidated financial statements.

Presentation – two-for-one stock split

On February 21, 2024, the Board of Directors of CSP Inc. approved an amendment to the Company’s Articles of Organization to increase the total number of its authorized shares of Common Stock, par value $0.01, from 7,500,000 shares to 9,753,900 shares (the “Amendment”). No shareholder approval was required under the Massachusetts Business Corporation Act with respect to the Amendment. The Amendment became effective upon filing with the Secretary of the Commonwealth of Massachusetts on February 21, 2024.

​

On June 26, 2024, the stockholders of CSP, Inc. approved an amendment to the Company's Articles of Organization, as amended (the "Articles of Organization"), to increase the number of authorized shares of Common Stock from 9,753,900 to 20,000,000 (the "Amendment"). On June 26, 2024, the Company filed an Articles of Amendment to the Articles of Organization with the Secretary of the Commonwealth of Massachusetts to effect the Amendment, which became effective immediately upon such filing. This amendment is included as Exhibit 3.1 and is incorporated herein by reference.

​

On February 21, 2024, the Company announced its Board of Directors approved and declared a two-for-one stock split to be effected in the form of a 100% stock dividend. The stock dividend was paid on March 20, 2024 to shareholders of record as of the close of business on March 6, 2024. In accordance with ASC 505 Equity, specifically ASC 505-20-25-3 through ASC 505-20-25-6, we have determined this had a material effect on reducing share market value and therefore was treated this event as a stock split for accounting purposes.

10

Table of Contents

All common shares and per share amounts contained in these condensed interim financial statements and notes have been retrospectively restated to reflect this two-for-one stock split in the form a 100% dividend in accordance with ASC 260 Earnings Per Share, specifically ASC 260-10-55-12.

Use of estimates

The preparation of condensed consolidated interim financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. These estimates and assumptions are related to the allowance for credit losses for accounts receivable and financing receivables, reserves for inventory obsolescence, the impairment assessment of intangible assets, right-of-use assets and lease liabilities, and the calculation of standalone selling price for revenue recognition, the calculation of liabilities related to deferred compensation and retirement plans and the calculation of income tax liabilities. Actual results may differ from those estimates under different assumptions or conditions.

Significant Accounting Policies

Except for the change in certain accounting policies upon adoption of the accounting standard described below, 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, 2023.

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting standards update (“ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326), an amendment of the FASB Accounting Standards Codification. Additional updates were issued in 2018-2020. The amended guidance replaces the current incurred loss impairment methodology for measurement of credit losses on financial instruments with a methodology (the “current expected credit losses model,” or “CECL model”) that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Under the CECL model, the allowance for losses on financial assets, measured at amortized cost, reflects management’s estimate of credit losses over the remaining expected life of such assets.

The Company adopted ASU 2016-13 (the “new CECL standard”) as of October 1, 2023 using the modified retrospective method, with a cumulative-effect adjustment to the opening balance of Shareholders’ equity as of October 1, 2023. The adoption primarily impacted the estimation of our Allowance for credit losses for Accounts receivable and Financing receivables. Additionally, it affected allowance for credit losses of contract assets with effects being immaterial. The total impact recorded on our initial adoption of ASU 2016-13 as of October 1, 2023 included an increase of Accounts receivable, net of $67k and a decrease of Financing receivables, net in the amount of $82k with the total adjustment decreasing retained earnings of $15k. For the accounting policies adopted and details of impacts from adoption refer to Note 4 - Accounts receivable, net and Note 5 - Financing receivables, net.

​

Recently Accounting Pronouncements Not Yet Adopted

Improvements to Reportable Segment Disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (ASU 2023-07), 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.

​

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.

11

Table of Contents

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.

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. Financing revenue pertaining to the portion of an arrangement containing a lease is recognized in accordance with ASC 842. Financing revenue related to the lease is recorded in revenue as equipment leasing is part of our operations.

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 integrated hardware and software, maintenance, and other services through the Multicomputer, Myricom, and ARIA product lines.

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 post contract maintenance and support. Post contract maintenance and support 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. ARIA Zero Trust Gateway (“AZT”) revenue contains two performance obligations: a software license and post contract support. The transaction price is generally fixed consideration and allocated based on relative stand-alone selling price. Software license revenue is recognized at a point in time, generally when the license is made available to the customer. Post contract support revenue is recognized ratably over the contractual period of generally one year.

Significant Judgments

The input method using labor hours expended relative to the total expected hours is used to recognize revenue for professional services. Only the hours that depict our performance toward satisfying a performance obligation are used to measure progress. An estimate of hours for each professional service agreement is made at the beginning of each contract

13

Table of Contents

based on prior experience and monitored throughout the performance of the services. This method is most appropriate as it depicts the measure of progress towards satisfaction of the performance obligation.

A financing component exists when at contract inception the period between the transfer of a promised good and/or service to the customer differs from when the customer pays for the good and/or service. As a practical expedient, we have elected not to adjust the amount of consideration for effects of a significant financing component when it is anticipated the promised good or service will be transferred and the subsequent payment will be one year or less.

​

Certain contracts contain a financing component including managed services contracts with financing of hardware and software. The interest rate used reflects the approximate interest rate consistent with a separate financing transaction with the customer at the inception of the agreement. 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.

​

When product and non-managed services are sold together, the allocation of the transaction price to each performance obligation is calculated based on the estimated relative selling price or a budgeted cost-plus margin approach, as appropriate. Due to the complex nature of these contracts, there is significant judgment in allocating the transaction price. These estimates are periodically reviewed by project managers, engineers, and other staff involved to ensure estimates remain appropriate. For items sold separately, including hardware, software, professional services, maintenance contracts, other services, and third-party service contracts, there is no allocation as there is one performance obligation.

We recognize revenue from third-party service contracts as either gross sales or net sales depending on whether we are acting as a principal party to the transaction or simply acting as an agent or broker based on control and timing. We are a principal if we control the good or service before that good or service is transferred to the customer. We record revenue as gross when we are a principal party to the arrangement and net of cost when we are acting as a broker or agent for a third party. Under gross sales recognition, the entire selling price is recorded in revenue and our cost to the third-party service provider or vendor is recorded in cost of sales. Under net sales recognition, the cost to the third-party service provider or vendor is recorded as a reduction to revenue resulting in net sales equal to the gross profit on the transaction. Third-party service contracts are sold in different combinations with hardware, software, and services. When we are an agent, revenue is typically recorded at a point in time. When we are the principal, revenue is recognized over the contract term. We have concluded we are the agent in sales of third-party maintenance, software or hardware support, and certain security software that is sold with integral third-party delivered software maintenance that includes critical updates.

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 $0.8 million and $0.9 million as of June 30, 2024 and September 30, 2023, respectively. The current portion is recorded in other current assets on the condensed consolidated balance sheets. There were no noncurrent contract assets as of June 30, 2024 and 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 $1.6 million and $1.9 million as of June 30, 2024 and September 30, 2023, respectively. The current portion of contract liabilities is recorded in deferred revenue on the condensed consolidated balance sheets. There were no long-term contract liabilities as of June 30, 2024 and September 30, 2023, respectively. Revenue recognized for the three and nine months ended June 30, 2024 that was included in contract liabilities as of September 30, 2023 was $0.2 million and $1.3 million, respectively.

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.

14

Table of Contents

Current capitalized contract costs are within the other current assets on the condensed consolidated balance sheets as of June 30, 2024 and September 30, 2023. The portion of current capitalized costs were $190 thousand and $172 thousand as of June 30, 2024 and September 30, 2023, respectively. There are no noncurrent capitalized costs on the condensed consolidated balance sheets as these commissions are paid annually even when the contract extends beyond a one year period. The amount of incremental costs amortized for the three months ended June 30, 2024 and 2023 were $122 thousand and $103 thousand, respectively. The amount of incremental costs amortized for the nine months ended June 30, 2024 and 2023 were $351 thousand and $302 thousand, respectively and is recorded in selling, general, and administrative expenses. There was no impairment related to incremental costs capitalized during the nine months ended June 30, 2024 and 2023.

Costs to fulfill a contract are capitalized when the costs are related to a contract or anticipated contract, generate or enhance resources that will be used in satisfying performance obligations in the future, and costs are recoverable. Costs to fulfill a contract are related to the TS portion of the business and involve activities performed before managed services can be completed. The were no current capitalized costs as of June 30, 2024 or September 30, 2023.

Other

Projects are typically billed upon completion or at certain milestones. Product 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 June 30, 2024 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. Net losses are not allocated to participating share-based payment awards, which include the non-vested shares outstanding.

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.

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

4. Accounts receivable, net

Upon adoption of the new CECL standard as described in Note 1 Basis of Presentation and New Significant Accounting Policy, 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.

Amounts disclosed below for the three and nine months ended June 30, 2024 reflect adoption of the new CECL standard and the amounts disclosed for the three and nine months ended June 30, 2023 reflect superseded guidance.

5. Financing receivables, net

​

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. 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, while accounts rated moderate risk have the equivalent of BB. The Company does not offer financing for customers where the risk is classified as higher, which would be lower than the equivalent of a BB Fitch rating.

Financing receivables, net carry an average weighted average interest rate of 7.1%, which reflects the approximate interest rate consistent with a separate financing transaction with the customer at the inception of the agreement.

The amount of interest income earned from sales whose payment terms exceed one year for the three months ended June 30, 2024 and 2023 was $177 thousand and $234 thousand, respectively. The amount of interest income earned from sales whose payment terms exceed one year for the nine months ended June 30, 2024 and 2023 was $528 thousand and $605 thousand, respectively. Interest income from these agreements is recorded in Other income (expense), net on the Condensed Consolidated Statements of Operations.

Amounts disclosed below as of June 30, 2024 reflect adoption of the new CECL standard and the amounts disclosed as of September 30, 2023 reflect superseded guidance.

​

Upon adoption of the new CECL standard as described in Note 1 Basis of Presentation and New Significant Accounting Policy, 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 June 30, 2024 or September 30, 2023.

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 June 30, 2024:

We evaluate inventory for obsolescence on at least a quarterly basis or more frequently if needed. Our HPP segment has a multi-faceted approach in determining obsolescence including reviewing inventory by product line, program, and individual part. In the TS segment, we seek to minimize obsolete inventory by having nearly all of our inventory purchased in conjunction with a sales agreement. From time to time, we do purchase certain inventory in bulk to receive discounts, but only when we anticipate selling this inventory. The inventory we purchase at the TS segment is in high demand, especially in the current environment, and has a limited risk of obsolescence.

8. Accounts payable and Other noncurrent liabilities

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

​

20

Table of Contents

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. As of June 30, 2024 the average imputed interest rate for the agreements was determined to be 8.2%. 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 June 30, 2024 and 2023 was $52 thousand and $74 thousand, respectively. Interest expense related to these agreements for the nine months ended June 30, 2024 and 2023 was $139 thousand and $185 thousand, respectively.

​

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

​

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

​

​ | ​ | ​ | ​ | ​ | ​
​ | June 30, 2024 | ​ | September 30, 2023
​ | (Amounts in thousands)
Current | $ | 2,477 | ​ | $ | 1,718
Less: discount | ​ | (264) | ​ | ​ | (140)
Accounts payable and accrued expenses | $ | 2,213 | ​ | $ | 1,578
​ | ​ | ​ | ​ | ​ | ​

Less: discount | ​ | (158) | ​ | ​ | (116)
Other noncurrent liabilities | $ | 2,286 | ​ | $ | 1,851

​

​

The Company had a total of approximately $1.4 million due (net of interest) to one of these vendors as of June 30, 2024. This is approximately 10% of Accounts payable and other noncurrent liabilities. The Company had a total of approximately $3.3 million due (net of interest) to one of these vendors as of September 30, 2023. This is approximately 26% of Accounts payable and other noncurrent liabilities. It was the same vendor as of June 30, 2024 and September 30, 2023 that only transacts with the US division of the TS segment. 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. Notes Payable and Line of Credit

In October 2019, the Company borrowed $2.0 million with a 5.1% rate of interest related to a multi-year agreement with a customer.

​

There was no interest expense related to the note payable for the nine months ended June 30, 2024. Interest expense related to the notes for the three and nine months ended June 30, 2023 was $5 thousand and $16 thousand, respectively.

​

As of June 30, 2024 and September 30, 2023, 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 June 30, 2024 and September 30, 2023, Company borrowings, all from the TS segment, under the inventory line of credit were $0.8

million and $1.5 million, respectively, and the Company was in compliance with all financial covenants. As of June 30, 2024 and September 30, 2023, this line of credit also includes availability of a limited cash withdrawal of up to $1.0 million. As of June 30, 2024 and September 30, 2023 there were no cash withdrawals outstanding.

​

10. Pension and Retirement Plans

The Company’s operations have defined benefit and defined contribution plans in the UK and in the US. In the UK, the Company provides defined benefit pension plans and defined contribution plans for some of its employees. In the US, the Company provides benefits through supplemental retirement plans to certain former employees. The US 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 US 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 UK is the only plan with plan assets. The plan assets consist of an investment in a commingled fund which in turn comprises a diversified mix of assets including corporate equity securities, government securities and corporate debt securities.

The components of net periodic benefit costs related to the US and UK plans are as follows:

11. Income Taxes

An income tax benefit of $75 thousand was recorded for the three months ended June 30, 2024 compared to an income tax benefit of $1.7 million in the same period of 2023. The estimated annualized effective income tax rate for the three months ended June 30, 2024 was 19.2%, excluding the impacts of the UK entity which continues to experience losses and maintains a full valuation allowance, compared to the estimated annualized effective income tax rate of 51.7% for the same period of 2023. The difference between our effective income tax rate and the U.S. federal statutory rate for the three months ending June 30, 2024 are the impact of state taxes and tax credits that we expect to be able to utilize against federal and state taxes. During the 3 months ending June 30, 2023, we released a significant portion of the valuation allowance against our U.S. deferred tax assets and switched from using the discrete effective tax rate method to calculate income taxes to the annualized effective tax rate method, resulting in the shift in the effective tax rate during the period.

​

The effective tax rate for the three months ended June 30, 2024 was 29.3%, excluding the UK as previously mentioned, driven by excess tax benefits on restricted stock awards vesting during the period. The effective tax rate for the three months ended June 30, 2023 was (201.9)%, excluding the UK, which was primarily driven by the release of a significant portion of the valuation allowance against our deferred tax assets in the U.S.

​

An income tax expense of $73 thousand was recorded for the nine months ended June 30, 2024 compared to an income tax benefit of $1.5 million in the same period of 2023. The estimated annualized effective income tax rate for the nine months ended June 30, 2024 was 19.2%, excluding the impacts of the UK entity which continues to experience losses and maintains a full valuation allowance, compared to the estimated annualized effective income tax rate of 22.0% for the nine months ended June 30, 2023. The difference between our effective income tax rate and the U.S. federal statutory rate for the three months ending June 30, 2024 and the same period of 2023 are the impact of state taxes and tax credits that we expect to be able to utilize against federal and state taxes.

​

The effective tax rate for the nine months ended June 30, 2024 was 4.9%, excluding the UK as previously mentioned, driven by excess tax benefits on restricted stock awards vesting during the period. The effective tax rate for

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 (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 June 30, 2024 or September 30, 2023.

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.

*Original maturity over one year

​

Cash and cash equivalents

Carrying amount approximated fair value.

​

Accounts and long-term receivable with original maturity over one year

Fair value was estimated by discounting future cash flows based on the current rate with similar terms.

​

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.

​

Notes Payable

Fair value was estimated by discounting future cash flows based on the current rate the Company could get in another transaction with similar terms based on historical information.

​

Fair value of accounts receivable with an original maturity of one year or less and accounts payable was not materially different from their carrying values as of June 30, 2024 and September 30, 2023.

Operating income (loss) 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 in fiscal year 2024 year as interest rates have increased significantly, 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, 2023. 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, our high dependence on contracts with the US federal government, our reliance in certain circumstances on single sources for supply of key product components, intense competition in the market segments in which we operate, changes in the US Tax laws, inflationary pressures, and the impact of the Ukraine-Russian military and Israeli-Hamas conflict on global trade and financial markets. 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, 2023.

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, 2023 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 nine months ended June 30, 2024 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, 2023 except for the estimation for credit losses. See Note 1 Basis of presentation and New Significant Accounting Policy in Item 1 to this Quarterly Report on Form 10-Q for details of the new policy.

Recent trends affecting our financial performance

As of June 30, 2024, 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.

​

The decrease in TS segment product sales of $4.1 million is due to decreased sales to several major customers in the US division. Service sales for the three months ended June 30, 2024 increased $0.3 million from the same prior year period, which was attributable to the US division. The increase in service sales included increased third party maintenance sales of $0.2 million and increased managed services sales of $0.1 million.

​

The HPP product sales decreased $1.0 million for the three months ended June 30, 2024 compared to the same prior year period as a result of decreased sales to one major customer of $0.8 million and decreased Myricom sales of $0.2 million to several other customers. The HPP service sales increased $0.2 million due to increased repair revenue of $0.2 million combined with increased customer support revenue for ARIA Zero Trust Gateway of $0.1 million, partially offset by decreased royalties of $0.1 million.

Our sales by geographic area, which is based on the customer location to which the products were shipped or services rendered, were as follows for the three months ended June 30, 2024 and 2023:

​

​

The $4.9 million decrease in sales to the Americas was primarily the result of a $3.9 million decrease in the TS segment’s US division combined with a decrease in the HPP segment of $1.0 million. The $0.1 million increase in sales to Europe was primarily the result of increased sales by our TS segment’s US division. The sales to Asia increased $0.2 million for the three months ended June 30, 2024 compared to the same prior year period due to an increase in the HPP segment.

Total | ​ | $ | 4,319 |  | 34 | % | $ | 5,059 |  | 31 | % | $ | (740) |  | 3 | %

​

The overall TS segment GM as a percentage of sales increased to 34% for the three month period ended June 30, 2024 compared to 31% 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 1% from the prior year due to a higher proportion of fixed costs compared to the prior year despite the increase in revenue.

​

The impact of product mix within our HPP segment on gross margin for the three months ended June 30, 2024 and 2023 was as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

Total | ​ | $ | 263 |  | 45 | % | $ | 868 |  | 65 | % | $ | (605) |  | (20) | %

​

The overall HPP segment GM as a percentage of sales decreased to 45% for the three months ended June 30, 2024 from 65% for the three months ended June 30, 2023. The 441% decrease in product GM as a percentage of product revenue for the three months ended June 30, 2024 compared to the same prior year period is due to significantly lower sales during the current period with fixed costs still being incurred which caused the significant change. The service GM as a percentage of services revenue from the same prior year period increased 13% to 60% for the three months ended June 30, 2024 compared to 47% for the three months ended June 30, 2023 due to increased ARIA GM.

Engineering and Development Expenses

The engineering and development expenses incurred by our HPP segment remained relatively flat at $0.7 million for the three months ended June 30, 2024 without any significant changes in category of expenses. 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.

​

SG&A expenses remained relatively flat at $4.6 million for the three months ended June 30, 2024 compared to the same prior year period. The $0.2 million decrease in TS segment SG&A expenses compared to the same prior year period is primarily the result of decreased variable compensation and accrued bonuses. The HPP segment SG&A expenses increased $0.2 million for the three months ended June 30, 2024 as compared to the prior year period due to increased consulting expenses.

​

Total other income, net for the three months ended June 30, 2024 increased $0.2 million to $0.5 million compared to $0.2 million for the three months ended June 30, 2023.

The $0.1 million decreased foreign exchange loss for the three months ended June 30, 2024 was primarily due to the US Dollar and Euro weakening less relative to the British Pound compared to the same prior year period. In consolidation, US dollars and Euros are remeasured into the functional currency, British Pounds, of our UK subsidiary. This non-cash remeasurement is included in the foreign exchange gain (loss) on the income statement. The foreign exchange loss was primarily from the US Dollar bank account in our TS UK division.

Interest income increased $0.1 million for the three months ended June 30, 2024 compared to the same prior year period primarily due to increased interest rates from the same prior year period, which has resulted in increased interest income from money market accounts in both the US and UK. There was a decrease in 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 year 2023 and 2024, this is more than offset by lower interest income recognized from prior agreements as interest income decreases as time elapses due to principal payments being received. All of these agreements are in the TS-US division.

The interest expense decrease of $27 thousand for the three months ended June 30, 2024 compared to the same prior year period was related to the TS US division making principal payments on multi-year vendor contracts that started in the second quarter of fiscal year 2021 related to sales agreements that have payment terms in excess of one year as the

Company incurs less interest expense over time as principal payments are made. See Note 8 Accounts payable and line of credit in Item 1 to this Quarterly Report on Form 10-Q for details. Additionally, there was no interest expense incurred in the current period for a note payable compared to the prior year as the note was paid in full the first day of fiscal year 2024. These decreases were partially offset by an increase of interest expense from several subsequent multi-year vendor agreements entered into in the third quarter of fiscal year 2023 and fiscal year 2024.

Income Taxes

An income tax benefit of $75 thousand was recorded for the three months ended June 30, 2024 compared to an income tax benefit of $1.7 million in the same period of 2023. The estimated annualized effective income tax rate for the three months ended June 30, 2024 was 19.2%, excluding the impacts of the UK entity which continues to experience losses and maintains a full valuation allowance, compared to the estimated annualized effective income tax rate of 51.7% for the same period of 2023. The difference between our effective income tax rate and the U.S. federal statutory rate for the three months ending June 30, 2024 are the impact of state taxes and tax credits that we expect to be able to utilize against federal and state taxes. During the 3 months ending June 30, 2023, we released a significant portion of the valuation allowance against our U.S. deferred tax assets and switched from using the discrete effective tax rate method to calculate income taxes to the annualized effective tax rate method, resulting in the shift in the effective tax rate during the period.

​

The effective tax rate for the three months ended June 30, 2024 was (29.3)%, excluding the UK as previously mentioned, driven by excess tax benefits on restricted stock awards vesting during the period. The effective tax rate for the three months ended June 30, 2023 was (201.9)%, excluding the UK, which was primarily driven by the release of a significant portion of the valuation allowance against our deferred tax assets in the U.S.

​

While the Company had maintained a full valuation allowance, we had been using the discrete effective tax rate method to calculate income taxes for the purposes of quarterly reporting. Now that the valuation allowance has been reduced, the Company has resumed using the annualized effective tax rate method to calculate income taxes as prescribed under ASC 740 and has done so for the three months ending June 30, 2024.

Sales

Our sales decreased by approximately $7.1 million, or 14%, to $42.2 million for the nine months ended June 30, 2024 as compared to $49.3 million for the nine months ended June 30, 2023. The decrease in sales is the result of a decrease of $5.6 million in our TS segment and a decrease of approximately $1.5 million in our HPP segment.

TS segment sales change was as follows for the nine months ended June 30, 2024 and 2023:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​

The decrease in TS segment product sales of $6.8 million during the period as compared to the prior year period is attributable to decreased sales with several major customers in the US division. Service sales for the nine months ended June 30, 2024 increased $1.2 million from the prior year period, which consists of a $1.3 million increase in the US division, partially offset by a $0.1 million decrease in the UK division. The changes in service sales include increased third party maintenance sales of $1.0 million and increased managed services sales of $0.5 million, partially offset by decreased internal and third party service sales of $0.3 million.

HPP segment sales change was as follows for the nine months ended June 30, 2024 and 2023:

​

The HPP product sales decreased by $1.6 million for the nine months ended June 30, 2024 as compared to the prior year period, primarily as a result of one large Myricom product order of $1.8 million in the prior year which did not reoccur in the current year combined with a decrease of $1.8 million from several major customers, which was partially offset during the current period by one large ARIA Zero Trust Gateway order of $2.0 million which did not occur in the prior year period. The HPP service sales increased $0.1 million for the nine months ended June 30, 2024 compared to the prior year period due to increased ARIA Trust Zero Gateway customer support revenue of $0.2 million and increased

revenue from other ARIA revenue of $0.1 million, partially offset by decreased royalties on high-speed processing boards related to the E2D program of $0.2 million.

Our sales by geographic area, which is based on the customer location to which the products were shipped or services rendered, were as follows for the nine months ended June 30, 2024 and 2023:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​

The $7.4 million decrease in sales to the Americas was the result of a decrease in the TS segment’s US division of $5.9 million and UK division of $0.1 million combined with a decrease in the HPP segment of $1.4 million. The sales to Europe remained relatively flat due to an increase in the TS segment’s US division of $0.1 million, offset by a $0.1 million decrease in the HPP segment. The sales to Asia increased $0.3 million as a result of increased sales in the TS segment’s US division.

Gross Margins

Our gross margin ("GM") decreased $1.6 million for the nine months ended June 30, 2024 as compared to the same prior year period. The GM as a percentage of total sales increased to 36% for the nine months ended June 30, 2024 as compared to the same prior year period of 34%.

Total | ​ | $ | 12,390 |  | 32 | % | $ | 13,218 |  | 30 | % | $ | (828) |  | 2 | %

​

The overall TS segment GM as a percentage of total sales increased to 32% for the nine month period ended June 30, 2024 compared to 30% from the prior year period. This is due to an increase in GM from services relative to products since services GM as a percentage of revenue is significantly higher than product GM as a percentage of revenue. Service GM as a percentage revenue remained relatively flat from the prior year without any significant changes in services type while there was a slight decrease in product GM as a percentage of revenue from the prior year due to product mix.

​

The overall HPP segment GM as a percentage of sales increased to 73% for the nine months ended June 30, 2024 from 66% for the nine months ended June 30, 2023. The 13% increase 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 nine months ended June 30, 2024, which was nearly all GM. The 6% decrease in service GM as a percentage of service revenue for the nine months ended June 30, 2024 compared to the same prior year period was due to decreased royalty sales, which are nearly all GM.

Engineering and Development Expenses

The engineering and development expenses incurred by our HPP segment decreased to $2.2 million for the nine months ended June 30, 2024 when compared to the same prior year period of $2.4 million due to lower consulting and decreased labor expenses of $0.2 million. 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.

​

SG&A expenses increased $0.7 million for the nine months ended June 30, 2024 compared to the same prior year period. The $0.1 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 $0.6 million for the nine months ended June 30, 2024 as compared to the prior year period due to increased consulting expenses of $0.2 million, increased stock compensation of $0.2 million, increased costs related to tradeshows and traveling of $0.1 million, and increased recruiting costs of $0.1 million.

​

Total other income, net for the nine months ended June 30, 2024 increased approximately $1.2 million to income of $1.3 million compared to income of $0.1 million in the same prior year period.

The $0.6 million decreased foreign exchange loss for the nine months ended June 30, 2024 was due to the US Dollar and Euro weakening less relative to the British Pound compared to the same prior year period. In consolidation, US dollars and Euros are remeasured into the functional currency, British Pounds, of our UK subsidiary. This non-cash remeasurement is included in the foreign exchange loss on the income statement. The foreign exchange loss was primarily from the US Dollar bank account in our TS UK division.

Interest income increased $0.5 million for the nine months ended June 30, 2024 compared to the same prior year period primarily due to increased interest rates from the same prior year period, which has resulted in increased interest income from money market accounts in both the US and UK. There was a slight decrease in 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 that have payment terms in excess of one year with higher interest rates have been entered into during fiscal year 2023 and 2024, this is more than offset by lower interest income recognized from prior agreements as interest income decreases as time elapses due to principal payments being received. All of these agreements are in the TS-US division.

The interest expense decrease of $58 thousand for the nine months ended June 30, 2024 compared to the same prior year period was related to the TS US division making principal payments on multi-year vendor contracts that started in the second quarter of fiscal year 2021 related to sales agreements that have payment terms in excess of one year as the Company incurs less interest expense over time as principal payments are made. Additionally, there was no interest expense incurred in the current period for the note payable compared to the prior year as the note was paid in full the first day of fiscal year 2024. These decreases were partially offset by an increase from several subsequent multi-year vendor agreement in the third quarter of fiscal year 2023 and fiscal year 2024. See Note 8 Accounts payable and other noncurrent liabilities in Item 1 to this Quarterly Report on Form 10-Q for details.

Income Taxes

An income tax expense of $73 thousand was recorded for the nine months ended June 30, 2024 compared to an income tax benefit of $1.5 million in the same period of 2023. The estimated annualized effective income tax rate for the nine months ended June 30, 2024 was 19.2%, excluding the impacts of the UK entity which continues to experience losses and maintains a full valuation allowance, compared to the estimated annualized effective income tax rate of 22.0% for the nine months ended June 30, 2023. The difference between our effective income tax rate and the U.S. federal statutory rate for the three months ending June 30, 2024 and the same period of 2023 are the impact of state taxes and tax credits that we expect to be able to utilize against federal and state taxes.

The effective tax rate for the nine months ended June 30, 2024 was 4.9%, excluding the UK as previously mentioned, driven by excess tax benefits on restricted stock awards vesting during the period. The effective tax rate for

37

Table of Contents

the nine months ended June 30, 2023 was (51.4)%, excluding the UK, which was primarily driven by the release of a significant portion of the valuation allowance against our deferred tax assets in the U.S.

While the Company had maintained a full valuation allowance, we had been using the discrete effective tax rate method to calculate income taxes for the purposes of quarterly reporting. Now that the valuation allowance has been reduced, the Company has resumed using the annualized effective tax rate method to calculate income taxes as prescribed under ASC 740 and has done so for the three and nine months ended June 30, 2024.

Liquidity and Capital Resources

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

Cash and cash equivalents increased by $3.7 million to $28.9 million as of June 30, 2024 from $25.2 million as of September 30, 2023.

The following is a summary of our cash flows for the nine months ended June 30, 2024 and 2023:

Increase (decrease) in cash and cash equivalents | ​ | $ | 3,674 |  | $ | (10,134)

​

Operating Activities

Cash provided by operating activities was $5.7 million for the nine months ended June 30, 2024 compared to $4.9 million used in operating activities in the prior year. The increase from the prior year is primarily related to an increase in accounts payable and accrued expenses of $9.1 million, decreased accounts receivable of $4.8 million and decreased other long-term liabilities of $1.7 million. These items were partially offset by decreased net income of $2.5 million, decreased other assets of $2.3 million, increased financing receivables of $0.8 million, and increased inventory of $0.1 million. 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. The remaining differences are primarily related to timing differences in operating assets and liabilities.

​

Investing Activities

Cash used in investing activities was $0.2 million for the nine months ended June 30, 2024 compared to $2.7 million for the prior year. The decrease in cash used from the prior year is primarily related to purchases of $3.5 million in held-to-maturity investments and proceeds of held-to-maturity investments of $1.2 million, which occurred in the prior year and did not reoccur in the nine months ended June 30, 2024.

Financing Activities

Cash used in financing activities was $1.8 million for the nine months ended June 30, 2024 compared to $2.6 million for the prior year period. The decrease was due to the timing in the net borrowing on our line-of-credit, which for the nine months ended June 30, 2024 we had a net payment of $0.7 million compared to a net payment of $1.8 million in the prior year period. This decrease in cash used in the current period was partially offset by increased cash dividends paid of $0.2 million from the prior year and $0.1 million of increased purchases of common stock.

If cash generated from operations is insufficient to satisfy working capital requirements, we may need to access funds through bank loans or other means. If we are unable to secure additional financing, we may not be able to complete 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 June 30, 2024. 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 June 30, 2024, the Company’s Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective.
