INNOVATIVE SOLUTIONS AND SUPPORT, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

​

1. Summary of Significant Accounting Policies

Certain of Innovative Solutions and Support, Inc.’s (the “Company,” “IS&S,” “we” or “us”) significant accounting policies are described below. All of the Company’s significant accounting policies are disclosed in the notes to the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2023.

Description of the Company

The Company was incorporated in Pennsylvania on February 12, 1988. The Company operates in one business segment as a systems integrator that designs, develops, manufactures, sells and services air data equipment, engine display systems, standby equipment, primary flight guidance, autothrottles and cockpit display systems for retrofit applications and original equipment manufacturers (“OEMs”). The Company supplies integrated flight management systems (“FMS”), flat panel display systems (“FPDS”), FPDS with autothrottle, air data equipment, integrated standby units, integrated standby units with autothrottle and advanced Global Positioning System (“GPS”) receivers that enable reduced carbon footprint navigation, communication and navigation products and inertial reference units.

The Company has continued to position itself as a system integrator, which capability provides the Company with the potential to generate more substantive orders over a broader product base. This strategy, as both a manufacturer and integrator, is designed to leverage the latest technologies developed for the computer and telecommunications industries into advanced and cost-effective solutions for the general aviation, commercial air transport and, United States Department of Defense (“DoD”)/governmental and foreign military markets. This approach, combined with the Company’s industry experience, is designed to enable IS&S to develop high-quality products and systems, to reduce product time to market and to achieve cost advantages over products offered by its competitors.

On June 30, 2023 (the “Acquisition Date”), the Company entered into an Asset Purchase and License Agreement with Honeywell International, Inc. (“Honeywell”) whereby Honeywell sold certain assets and granted perpetual license rights to manufacture and sell licensed products related to its inertial, communication and navigation product lines (the “Product Lines”) to the Company (the “Transaction”). The Transaction involved a sale of certain inventory, equipment and customer-related documents; an assignment of certain customer contracts; and a grant of exclusive and non-exclusive licenses to use certain Honeywell intellectual property related to its inertial, communication and navigation product lines to repair, overhaul, manufacture sell, import, export and distribute certain products to the Company. See Acquisition within Note 2, “Supplemental Balance Sheet Disclosures” below for more details.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements are presented pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”) in accordance with the disclosure requirements for the quarterly report on Form 10-Q and, therefore, do not include all of the information and footnotes required by generally accepted accounting principles in the United States (“GAAP”) for complete annual financial statements. In the opinion of Company management, the unaudited condensed consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) necessary to state fairly the results for the interim periods presented. The condensed consolidated balance sheet as of September 30, 2023 is derived from the audited financial statements of the Company. Operating results for the three- and nine-month periods ended June 30, 2024 are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2024 which cannot be determined at this time. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes of the Company included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2023.

Principles of Consolidation

The Company’s condensed consolidated financial statements include the accounts of its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Table of Contents

Use of Estimates

The financial statements of the Company have been prepared in accordance with GAAP, which require management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results could differ from those estimates. Estimates are used in accounting for, among other items, valuation of tangible and intangible assets acquired, long term contracts, evaluation of allowances for doubtful accounts, inventory obsolescence, product warranty cost liabilities, income taxes, engineering and material costs on Engineering Development Contract (“EDC”) programs, percentage of completion on EDC contracts, the useful lives of long-lived assets for depreciation and amortization, the recoverability of long-lived assets, evaluation of goodwill impairment and contingencies. Estimates and assumptions are reviewed periodically and the effects of changes, if any, are reflected in the condensed consolidated statements of operations in the period they are determined.

Principles of Acquisitions

The Company evaluates each of its acquisitions in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805, “Business Combinations” (“ASC 805”), to determine whether the transaction is a business combination or an asset acquisition. In determining whether an acquisition should be accounted for as a business combination or an asset acquisition, the Company first performs a screen test to determine whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this is the case, the acquired set is not deemed to be a business and is instead accounted for as an asset acquisition. If this is not the case, the Company then further evaluates whether the acquired set includes, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. If so, the Company concludes that the acquired set is a business.

The Company accounts for business acquisitions using the acquisition method of accounting. Under this method of accounting, assets acquired and liabilities assumed are recorded at their respective fair values at the date of the acquisition. When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions. The Company’s estimates of fair value are based upon assumptions believed to be reasonable, but are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Any excess of the purchase price over the fair value of the net assets acquired is recognized as goodwill.

During the measurement period, which may be up to one year from the acquisition date, the Company adjusts the provisional amounts of assets acquired and liabilities assumed with the corresponding offset to goodwill to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded within the Company’s condensed consolidated statements of operations.

Intangible Assets

The Company’s identifiable intangible assets primarily consist of license agreement and customer relationships. Intangible assets acquired in a business combination are recognized at fair value using generally accepted valuation methods deemed appropriate for the type of intangible asset acquired and are reported separately from any goodwill recognized.

Intangible assets with a finite life are amortized over their estimated useful life and are reported net of accumulated amortization. They are assessed for impairment in accordance with the Company’s policy on assessing long-lived assets for impairment described in the notes of the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2023.

Indefinite-lived intangible assets are not amortized, but are subject to an annual impairment test, or when events or circumstances dictate, more frequently. The impairment review for indefinite-lived intangible assets can be performed using a qualitative or quantitative impairment assessment. The quantitative assessment consists of a comparison of the fair value of the indefinite-lived intangible asset with its carrying amount. If the carrying amount exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. If the fair value exceeds its carrying amount, the indefinite-lived intangible asset is not considered impaired.

Goodwill

Goodwill represents the future economic benefit arising from other assets acquired that could not be individually identified and separately recognized. The recorded amounts of goodwill from business combinations are based on management’s best estimates of the fair values of assets acquired and liabilities assumed at the date of acquisition. Goodwill is assigned to the reporting units that are

7

Table of Contents

expected to benefit from the synergies of the business combination that generated the goodwill. The Company’s goodwill impairment test is performed at the reporting unit level. Reporting units are determined based on an evaluation of the Company’s operating segments and the components making up those operating segments.

Goodwill is tested for impairment at fiscal year-end September 30 or in an interim period if certain changes in circumstances indicate a possibility that an impairment may exist. Factors to consider that may indicate an impairment may exist are:

| ● | macroeconomic conditions;

| ● | industry and market considerations, such as a significant adverse change in the business climate;

| ● | cost factors;

| ● | overall financial performance, such as current-period operating results or cash flow declines combined with a history of operating results or cash flow declines;

| ● | a projection or forecast that demonstrates continuing declines in the cash flow or the inability to improve the operations to forecasted levels; and

| ● | any entity-specific events.

If the Company determines that it is more likely than not that the fair value of the reporting unit is below the carrying amount as part of its qualitative assessment, a quantitative assessment of goodwill is required. In the quantitative evaluation, the fair value of the reporting unit is determined and compared to the carrying value. If the fair value is greater than the carrying value, then the goodwill is deemed not to be impaired and no further action is required. If the fair value is less than the carrying value, goodwill is considered impaired and a charge is reported as impairment of goodwill in the condensed consolidated statements of operations.

Fair Value of Financial Instruments

The net carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate their fair value because of the short-term nature of these instruments. The carrying value of our debt approximates fair value as the interest rate is variable and approximates current market levels. For financial assets and liabilities measured at fair value on a recurring basis, fair value is the price the Company would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant at the measurement date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value as follows:

Level 1 — Unadjusted quoted prices that are available in active markets for the identical assets or liabilities at the measurement date.

Level 2 — Other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly, including:

| ● | Quoted prices for similar assets or liabilities in active markets;

| ● | Quoted prices for identical or similar assets in non-active markets;

| ● | Inputs other than quoted prices that are observable for the asset or liability; and

| ● | Inputs that are derived principally from or corroborated by other observable market data.

Level 3 — Unobservable inputs that cannot be corroborated by observable market data and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions.

Revenue Recognition

The Company enters into sales arrangements with customers that, in general, provide for the Company to design, develop, manufacture, deliver and service large flat-panel display systems, flight information computers, autothrottles and advanced monitoring systems that measure and display critical flight information, including data relative to aircraft separation, airspeed, altitude and engine and fuel data measurements.

Revenue from Contracts with Customers

The Company accounts for revenue in accordance with ASC 606, “Revenue from Contracts with Customers” (“ASC 606”). The core principle of ASC 606 is that an entity recognizes revenue when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these goods or services. To achieve this core principle, the Company applies the following five steps:

| 1) | Identify the contract with a customer

The Company’s contract with its customers typically is in the form of a purchase order issued to the Company by its customers and, to a lesser degree, in the form of a purchase order issued in connection with a formal contract executed with a customer. For the purpose of accounting for revenue under ASC 606, a contract with a customer exists when (i) the Company enters into an enforceable contract with a customer that defines each party’s rights regarding the goods or services to be transferred and identifies the payment terms related to these goods or services, (ii) the contract has commercial substance and, (iii) the Company determines that collection of substantially all consideration for goods or services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. The Company applies judgment in determining the customer’s ability and intention to pay, which is based on a variety of factors including the customer’s historical payment experience or, in the case of a new customer, published credit and financial information pertaining to the customer.

| 2) | Identify the performance obligations in the contract

Performance obligations promised in a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the good or service either on its own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the goods or services is separately identifiable from other promises in the contract. Most of our revenue is

9

Table of Contents

derived from purchases under which we provide a specific product or service and, as a result, there is only one performance obligation. In the event that a contract includes multiple promised goods or services, such as an EDC contract which includes both engineering services and a resulting product shipment, the Company must apply judgment to determine whether promised goods or services are capable of being distinct in the context of the contract. In these cases, the Company considers whether the customer could, on its own, or together with other resources that are readily available from third parties, produce the physical product using only the output resulting from the Company’s completion of engineering services. If the customer cannot produce the physical product, then the promised goods or services are accounted for as a combined performance obligation.

| 3) | Determine the transaction price

The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring goods or services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur.

| 4) | Allocate the transaction price to performance obligations in the contract

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. If the contract contains multiple performance obligation, the Company determines standalone selling price based on the price at which each performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price by taking into account available information such as market conditions as well as the cost of the goods or services and the Company’s normal margins for similar performance obligations.

| 5) | Recognize revenue when or as the Company satisfies a performance obligation

The Company satisfies performance obligations either over time or at a point in time as discussed in further detail below. Revenue is recognized at the time the related performance obligation is satisfied by transferring a promised good or service to a customer. The Company has also recognized revenue from EDC contracts and is recognized over time using an input measure (e.g., costs incurred to date relative to total estimated costs at completion) to measure progress. Contract costs include material, components and third-party avionics purchased from suppliers, direct labor and overhead costs.

Contract Estimates

Accounting for performance obligations in long-term contracts that are satisfied over time involves the use of various techniques to estimate progress towards satisfaction of the performance obligation. The Company typically measures progress based on costs incurred compared to estimated total contract costs. Contract cost estimates are based on various assumptions to project the outcome of future events that often span more than a single year. These assumptions include the amount of labor and labor costs, the quantity and cost of raw materials used in the completion of the performance obligation and the complexity of the work to be performed.

As a significant change in one or more of these estimates could affect the profitability of our contracts, we review and update our contract-related estimates regularly. We recognize adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the total loss in the quarter in which it is identified.

The impact of adjustments in contract estimates on our operating earnings can be reflected in either operating costs and expenses or revenue. The aggregate impact of adjustments in contract estimates did not change our revenue and operating earnings (and diluted earnings per share) for the three- and nine-month periods ended June 30, 2024 and 2023. Therefore, no adjustment on any contract was material to our condensed consolidated financial statements for the three- and nine-month periods ended June 30, 2024 and 2023.

Contract Balances

Contract assets consist of the right to consideration in exchange for product offerings that we have transferred to a customer under the contract. Contract liabilities primarily relate to consideration received in advance of performance under the contract. The following table reflects the Company’s contract assets and contract liabilities:

Concentrations

Major Customers and Products

In the three-month period ended June 30, 2024, two customers, Pilatus Aircraft Ltd (“Pilatus”) and Lufthansa Technik AG, accounted for 21% and 10% of net sales, respectively. In the nine-month period ended June 30, 2024, one customer, Pilatus accounted for 26% of net sales.

In the three-month period ended June 30, 2023, three customers, Pilatus, Air Transport Services Group (“ATSG”) and Textron Aviation, Inc. (“Textron”), accounted for 25%, 24% and 10% of net sales, respectively. In the nine-month period ended June 30, 2023, three customers, Pilatus, ATSG and Textron, accounted for 27%, 18% and 10% of net sales, respectively.

Major Suppliers

The Company buys several of its components from sole source suppliers. Although there are a limited number of suppliers of particular components, management believes other suppliers could provide similar components on comparable terms.

For the three- and nine-month periods ended June 30, 2024, the Company had two and one suppliers, respectively, that were individually responsible for greater than 10% of the Company’s total inventory related purchases.

For the three- and nine-month periods ended June 30, 2023, the Company had four suppliers, respectively, that were individually responsible for greater than 10% of the Company’s total inventory related purchases.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash balances and accounts receivable. The Company invests its excess cash where preservation of principal is the major consideration. Cash balances are maintained with two major banks. Balances on deposit with certain money market accounts and operating accounts may exceed the Federal Deposit Insurance Corporation limits. The Company’s customer base consists principally of companies within the aviation industry. The Company requests advance payments and/or letters of credit from customers that it considers to be credit risks.

Change in Accounting Estimate

Effective April 1, 2024, the Company changed its method of computing depreciation from accelerated methods to the straight-line method for the Company’s property and equipment, except for the manufacturing facility which was already depreciating using the straight-line method. Based on ASC 250, “Accounting Changes and Error Corrections”, the Company determined that the change in depreciation method from an accelerated method to a straight-line method is a change in accounting estimate affected by a change in accounting principle. Per the guidance, a change in accounting estimate affected by a change in accounting principle is to be applied prospectively. The change is considered preferable because the straight-line method will more accurately reflect the pattern of usage

11

Table of Contents

and the expected benefits of such assets and provide greater consistency with the depreciation methods used by other companies in the Company’s industry. The net book value of assets acquired with useful lives remaining will be depreciated using the straight-line method prospectively. As a result of the change to the straight-line method of depreciating the assets, accumulated depreciation and depreciation expense decreased by $113,000 for the three- and nine-month periods ended June 30, 2024.

Recently Adopted Accounting Pronouncements

In June 2016, FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instrument” (“ASU 2016-13”). ASU 2016-13 replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 is effective for SEC small business filers for fiscal years beginning after December 15, 2022. The adoption of this standard did not have a material impact on our condensed consolidated financial statements or related disclosures.

Acquisition

On June 30, 2023, the Company entered into an Asset Purchase and License Agreement with Honeywell whereby Honeywell sold certain assets and granted perpetual license rights to manufacture and sell licensed products related to its inertial, communication and navigation product lines to the Company. The Transaction involves a sale of certain inventory, equipment and customer-related documents; an assignment of certain customer contracts; and a grant of exclusive and non-exclusive licenses to use certain Honeywell intellectual property related to its inertial, communication and navigation product lines to repair, overhaul, manufacture sell, import, export and distribute certain products to the Company. The Transaction allows the Company to diversify its product offerings in the aerospace industry. The Company determined that the Transaction met the definition of a business under ASC 805; therefore, the Company accounted for the Transaction as a business combination and applied the acquisition method of accounting.

In connection with the Transaction, the Company entered into a term loan with PNC Bank, National Association for $20.0 million to fund a portion of the Transaction (the “Term Loan”) – refer to Note 9, “Loan Agreement” for further details. The purchase consideration transferred at the Acquisition Date was $35.9 million, which was entirely cash.

In the third quarter of 2024 and within one year from the Acquisition Date, the Company finalized its accounting of the Transaction. The following purchase price allocation table presents the Company's estimates of the fair value of assets acquired and liabilities assumed as of the Acquisition Date, and subsequent measurement period adjustments recorded during the one-year period ended June 30, 2024:

Table of Contents

|  | value of finished goods was determined based on the estimated selling price, net of selling costs and a margin on the selling activities, which resulted in a change in the value of the finished goods.

| (b) | Intangible assets consist of license agreement related to the license rights to use certain Honeywell intellectual property and customer relationships and are recorded at estimated fair values. The estimated fair value of the license agreement is based on a variation of the income valuation approach and is determined using the relief from royalty method. The estimated fair value of the customer relationships is based on a variation of the income valuation approach known as the multi-period excess earnings method. Refer to Intangible assets within Note 2, “Supplemental Balance Sheet Disclosures” for further details.

| (c) | Goodwill represents the excess of the purchase consideration over the estimated fair value of the assets acquired and liabilities assumed. The goodwill recognized is primarily attributable to the expected synergies from the Transaction. Goodwill resulting from the Transaction has been assigned to the Company’s one operating segment and one reporting unit. The goodwill is not expected to be deductible for income tax purposes. Further, the Company determined that the goodwill was not impaired as of June 30, 2024 and as such, no impairment charges have been recorded for the three- and nine-month periods ended June 30, 2024; the Company also determined that the goodwill was not impaired as of September 30, 2023.

| (d) | In the third quarter of 2024 and within one year from the Acquisition Date, the Company identified measurement period adjustments related to fair value estimates. The measurement period adjustments were due to the refinement of inputs used to calculate the fair value of the prepaid inventory, equipment, license agreement and customer relationships based on facts and circumstances that existed as of the Acquisition Date. One of the refinements of inputs used was a change in classification of prepaid inventory to equipment of $3.7 million. The adjustments resulted in an overall increase to goodwill of $3.0 million. As a result of the measurement period adjustments to the estimated fair values of equipment and customer relationships, during the third quarter of 2024, the Company recognized $218,623 additional depreciation expense in cost of sales and $67,500 additional amortization expense in selling, general and administrative respectively, related to the effects that would have been recognized in previous quarters if the measurement period adjustments were recognized as of the Acquisition Date. For the remaining measurement period adjustments, the change to the preliminary fair value estimates did not have a material impact to the condensed consolidated statement of operations.

| (e) | During the fourth quarter of 2023, the Company identified measurement period adjustments related to the fair value estimates for accrued expenses. While the Asset Purchase and License Agreement indicated an amount of liabilities related to open supplier purchase orders to be assumed by the Company as of the Acquisition Date, it was determined that there were no actual liabilities outstanding related to these open supplier purchase orders as of the Acquisition Date; therefore, the $3.5 million assumed liabilities preliminarily recorded were reversed. The adjustments resulted in an overall decrease to goodwill of $3.5 million; the adjustments have no impact to the condensed consolidated statement of operations.

Transition services agreement

Concurrent with the Transaction, the Company entered into a transition services agreement (the “TSA”) with Honeywell, at no additional costs, to receive certain transitional services and technical support during the transition service period. The Company accounted for the TSA separate from business combination and have recognized $140,000 in prepaid expenses and other current assets at September 30, 2023 within the condensed consolidated balance sheets for the services to be received in the future from Honeywell. The prepaid expense related to the TSA was determined using the with and without method.

Acquisition and related costs

In connection with the Transaction, the Company incurred no acquisition costs for the three- and nine-month periods ended June 30, 2024. The Company incurred acquisition costs of $408,961, which were expensed as incurred and included in selling, general and administrative expenses in the condensed consolidated statement of operations for the year ended September 30, 2023; of that amount, the Company incurred acquisition costs of $262,099, which were expensed as incurred and included in selling, general and administrative expenses in the condensed consolidated statement of operations for the three- and nine-month periods ended June 30, 2023. The debt issuance costs related to the Term Loan were not material.

​

| (a) | As part of the Transaction, the Company acquired intangible assets related to the license agreement for the license rights to use certain Honeywell intellectual property and customer relationships. The license agreement has an indefinite life and is not subject to amortization; the customer relationships have an estimated weighted average life of nine years. The Company determined that the intangible assets were not impaired as of June 30, 2024 and September 30, 2023; no impairment charges have been recorded for the three- and nine-month periods ended June 30, 2024.

| (b) | The licensing and certification rights are amortized over a defined number of units. No impairment charges were recorded during the three-and nine-month periods ended June 30, 2024. An impairment charge of $44,400 was recorded during the three-and nine-month periods ended June 30, 2023.

Intangible asset amortization expense was $358,500 and $1,063 for the three-month periods ended June 30, 2024 and 2023, respectively. Intangible asset amortization expense for the three-month periods ended June 30, 2024 and 2023 was charged to selling, general and administrative expense.

​

Intangible asset amortization expense was $895,500 and $1,063 for the nine-month periods ended June 30, 2024 and 2023, respectively. Intangible asset amortization expense for the nine-month periods ended June 30, 2024 and 2023 was charged to selling, general and administrative expense.

​

The timing of future amortization expense is not determinable for the licensing and certification rights because they are amortized over a defined number of units. The expected future amortization expense related to the customer relationships as of June 30, 2024 is as follows:

3. Income Taxes

The Company will continue to assess all available evidence during future periods to evaluate any changes to the realization of its deferred tax assets. If the Company were to determine that it would be able to realize additional state deferred tax assets in the future, it would make an adjustment to the valuation allowance which would reduce the provision for income taxes.

As a result of the 2017 Tax Cuts and Jobs Act, the Company must amortize amounts paid or incurred for specified research and development expenditures, including software development expenses, ratably over 60 months, beginning at the mid-point of the tax year in which the expenditures are paid or incurred.

The effective tax rate for the three-month periods ended June 30, 2024 and 2023 were 17.6% and 19.3%, respectively. This effective tax rate differs from the statutory tax rate primarily due to an increased R&D credit, as well as permanent items and state taxes.

The effective tax rate for the nine-month periods ended June 30, 2024 and 2023 were 19.9% and 20.5%, respectively. This effective tax rate differs from the statutory tax rate primarily due to an increased R&D credit, as well as permanent items and state taxes.

4. Shareholders’ Equity and Share-Based Payments

At June 30, 2024, the Company’s Amended and Restated Articles of Incorporation provides the Company authority to issue 75,000,000 shares of common stock and 10,000,000 shares of preferred stock.

Share-Based Compensation

The Company accounts for share-based compensation under the provisions of ASC Topic 718, “Compensation – Stock Compensation”, by using the fair value method for expensing stock options and stock awards.

Amended and Restated 2019 Stock-Based Incentive Compensation Plan

The Company’s Amended and Restated 2019 Stock-Based Incentive Compensation Plan was approved by the Company’s shareholders at the Company’s Annual Meeting of Shareholders held on April 18, 2024, which amended and restated the 2019 Stock-Based Incentive Compensation Plan approved by the Company’s shareholders on April 2, 2019 (as Amended, the “Amended and Restated 2019 Plan”). The Amended and Restated 2019 Plan authorizes the grant of stock appreciation rights, restricted stock, options

Table of Contents

and other equity-based awards. Options granted under the Amended and Restated 2019 Plan may be either “incentive stock options” as defined in section 422 of the Code or nonqualified stock options, as determined by the Compensation Committee.

Subject to an adjustment necessary upon a stock dividend, recapitalization, forward split or reverse split, reorganization, merger, consolidation, spin-off, combination, repurchase or share exchange, extraordinary or unusual cash distribution, or similar corporate transaction or event, the maximum number of shares of common stock available for awards under the Amended and Restated 2019 Plan is 1,950,000, plus the shares that were authorized to be granted but have not been issued under the Company’s 2009 Stock-Based Incentive Compensation Plan as of the effective date of the Amended and Restated 2019 Plan (i.e., April 18, 2024).

If any award is forfeited, terminates or otherwise is settled for any reason without an actual distribution of shares to the participant, the related shares of common stock subject to such award will again be available for future grant. Any shares tendered by a participant in payment of the exercise price of an option or the tax liability with respect to an award (including, in any case, shares withheld from any such award) will not be available for future grant under the Amended and Restated 2019 Plan. If there is any change in the Company’s corporate capitalization, the Compensation Committee must proportionately and equitably adjust the number and kind of shares of common stock which may be issued in connection with future awards, the number and kind of shares of common stock covered by awards then outstanding under the Amended and Restated 2019 Plan, the aggregate number and kind of shares of common stock available under the Amended and Restated 2019 Plan, any applicable individual limits on the number of shares of common stock available for awards under the Amended and Restated 2019 Plan, the exercise or grant price of any award, or if deemed appropriate, make provision for a cash payment with respect to any outstanding award. In addition, the Compensation Committee may make adjustments in the terms and conditions of any awards, including any performance goals, in recognition of unusual or nonrecurring events affecting the Company or any subsidiary, or in response to changes in applicable laws, regulations, or accounting principles.

The compensation expense related to stock options and awards issued to employees under the Amended and Restated 2019 Plan was $191,623 and $566,952 for the three- and nine-month periods ended June 30, 2024, respectively.

​

Net income per share is calculated pursuant to ASC Topic 260, “Earnings per Share”. Basic earnings per share (“EPS”) excludes potentially dilutive securities and is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS is computed assuming the conversion or exercise of all dilutive securities such as employee stock options and restricted stock units (“RSUs”).

The number of incremental shares from the assumed exercise of stock options and RSUs is calculated by using the treasury stock method. As of June 30, 2024 and 2023, there were 361,613 and 128,815 options to purchase common stock outstanding, respectively, and 250,975 and 76,636 shares subject to vesting of restricted stock units outstanding, respectively. The average outstanding diluted shares calculation excludes options with an exercise price that exceeds the average market price of shares during the period.

For the three-month periods ended June 30, 2024 and 2023, respectively, 529,918 and 312,210 diluted weighted-average shares outstanding were excluded from the computation of diluted EPS because the effect would be anti-dilutive.

For the nine-month periods ended June 30, 2024 and 2023, respectively, 329,026 and 196,577 diluted weighted-average shares outstanding were excluded from the computation of diluted EPS because the effect would be anti-dilutive.

6. Commitments and Contingencies

In the ordinary course of business, the Company is at times subject to various legal proceedings and claims. The Company does not believe any such matters that are currently pending will, individually or in aggregate, have a material effect on the results of operations or financial position.

​

8. Leases

The Company accounts for leases in accordance with ASU 2016-02, “Leases” (“ASU 2016-02”), and records right-of-use assets and corresponding lease liabilities on the balance sheet for most leases with an initial term of greater than one year. Consistent with

19

Table of Contents

previous accounting guidance, we will recognize payments for leases with a term of less than one year in the statement of operations on a straight-line basis over the lease term.

We lease real estate and equipment under various operating leases. A lease exists when a contract or part of a contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. In determining whether a lease exists, we consider whether a contract provides us with both: (a) the right to obtain substantially all of the economic benefits from the use of the identified asset and (b) the right to direct the use of the identified asset.

Some of our leases include base rental periods coupled with options to renew or terminate the lease, generally at our discretion. In evaluating the lease term, we consider whether we are reasonably certain to exercise such options. To the extent a significant economic incentive exists to exercise an option, that option is included within the lease term. However, based on the nature of our lease arrangements, options generally do not provide us with a significant economic incentive and are therefore excluded from the lease term for the majority of our arrangements.

Our leases typically include a combination of fixed and variable payments. Fixed payments are generally included when measuring the right-of-use asset and lease liability. Variable payments, which primarily represent payments based on usage of the underlying asset, are generally excluded from such measurement and expensed as incurred. In addition, certain of our lease arrangements may contain a lease coupled with an arrangement to provide other services, such as maintenance, or may require us to make other payments on behalf of the lessor related to the leased asset, such as payments for taxes or insurance. As permitted by ASU 2016-02, we have elected to account for these non-lease components together with the associated lease component if included in the lease payments. This election has been made for each of our asset classes.

The measurement of right-of-use assets and lease liabilities requires us to estimate appropriate discount rates. To the extent the rate implicit in the lease is readily determinable, such a rate is utilized. However, based on information available at lease commencement for our leases, the rate implicit in the lease is not known. In these instances, we utilize an incremental borrowing rate, which represents the rate of interest that we would pay to borrow on a collateralized basis over a similar term.

The following table presents the lease-related assets and liabilities reported in the Condensed Consolidated Balance Sheet as of June 30, 2024:

​

​ | ​ | ​ | ​ | ​ | ​
Classification on the Consolidated Balance Sheet on June 30, 2024

9. Loan Agreement

​

On June 28, 2023, the Company and one of its subsidiaries entered into an Amendment to Loan Documents (the “Loan Amendment”) with PNC Bank, National Association (“PNC”), which amends certain terms of that certain Loan Agreement entered into by the parties on May 11, 2023 (the “Loan Agreement” and, as amended, the “Amended Loan Agreement”) and (ii) a corresponding Term Note in favor of PNC (the “Term Note”), which together provide for a senior secured term loan in an aggregate principal amount of $20.0 million, with a maturity date of June 28, 2028. Availability of funds under the Term Loan was conditioned upon the closing of the transactions contemplated by the Amended Loan Agreement and was used to fund a portion of the Transaction. Under the agreement, the Company has the right to prepay any amounts outstanding at any time and from time to time, whole or in part; subject to payment of any break funding indemnification amounts.

​

The interest rate applicable to loans outstanding under the Term Loan is a floating interest rate equal to the sum of (A) the Term SOFR Rate (as defined in the Term Note) plus (B) an unadjusted spread of the Applicable SOFR Margin plus (C) a SOFR adjustment of ten basis points. The Applicable SOFR Margin ranges from 1.5% to 2.5% depending on the Company’s funded debt to EBITDA ratio. Commencing on June 30, 2023, the Term Loan will consist of sixty equal monthly principal installments, over a period of ten years, with the balance payable on the maturity date of the Term Loan.

​

In addition to providing for the Term Loan, the Loan Agreement, together with a corresponding Revolving Line of Credit Note in favor of PNC, executed May 11, 2023 (“Line of Credit Note”), provides for a senior secured revolving line of credit in an aggregate principal amount of $10,000,000, with an expiration date of May 11, 2028 (the “Revolving Line of Credit”).

​

The interest rate applicable to loans outstanding under the Revolving Line of Credit was a rate per annum equal to the sum of (A) Daily SOFR (as defined in the Line of Credit Note) plus (B) an unadjusted spread of Applicable SOFR Margin plus (C) a SOFR adjustment of ten basis points. The Applicable SOFR Margin ranges from 1.5% to 2.5% depending on the Company’s funded debt to EBITDA ratio. The Company will pay an annual commitment fee of 0.15% on the amount available for borrowing under the revolving credit facility.

​

On December 19, 2023, the Company and PNC entered into an Amendment to the Loan (the “Restated Loan Amendment”) and a corresponding Amended and Restated Revolving Line of Credit Note (“Restated Line of Credit Note”) and Amended and Restated Line of Credit and Investment Sweep Rider (the “Restated Rider”), to increase the aggregate principal amount available under the Company’s senior secured revolving line of credit from $10,000,000 to $30,000,000 and extend the maturity date until December 19, 2028. Under the terms of the Restated Rider, at the end of each business day any cash balance will be applied by PNC to the outstanding principal balance under the terms of the Restated Line of Credit Note.

Company Overview

Innovative Solutions and Support, Inc. was incorporated in Pennsylvania on February 12, 1988. The Company operates in one business segment as a systems integrator that designs, develops, manufactures, sells and services air data equipment, engine display systems, standby equipment, primary flight guidance, autothrottles and cockpit display systems for retrofit applications and original equipment manufacturers (“OEMs”). The Company supplies integrated flight management systems (“FMS”), flat panel display systems (“FPDS”), FPDS with autothrottle, air data equipment, integrated standby units, integrated standby units with autothrottle and advanced GPS receivers that enable reduced carbon footprint navigation, communication and navigation products and inertial reference units.

The Company has continued to position itself as a system integrator, which provides the Company with the capability and potential to generate more substantive orders over a broader product base. This strategy, as both a manufacturer and integrator, is designed to leverage the latest technologies developed for the computer and telecommunications industries into advanced and cost-effective solutions for the general aviation, commercial air transport, United States Department of Defense (“DoD”)/governmental and foreign military markets. This approach, combined with the Company’s industry experience, is designed to enable IS&S to develop high-quality products and systems, to reduce product time to market and to achieve cost advantages over products offered by its competitors.

The Company has been working with advances in technology to provide pilots with more information to enhance both the safety and efficiency of flying, and has developed its COCKPIT/IP® Cockpit Information Portal (“CIP”) product line, which incorporates proprietary technology, lower cost relative to the competition, reduced power consumption, decreased weight and increased functionality. The Company has incorporated Electronic Flight Bag (“EFB”) functionality, such as charting and mapping systems, into its FPDS product line.

The Company has developed an FMS that combines the savings long associated with in-flight fuel optimization in enroute flight management with the precision of satellite-based navigation required to comply with the regulatory environments of both domestic and international markets. The Company believes that its FMS, alongside its FPDS and CIP product lines, is well suited to address market demand driven by certain regulatory mandates, new technologies and the high cost of maintaining aging and obsolete equipment on aircraft that may be in service for up to fifty years. The shift in the regulatory and technological environment is illustrated by the dramatic increase in the number of Space Based Augmentation System (“SBAS”) or Wide Area Augmentation System (“WAAS”) approach qualified airports, particularly as realized through Localizer Performance with Vertical guidance (“LPV”) navigation procedures. Aircraft equipped with the Company’s FMS, FPDS and SBAS/WAAS/LPV enabled navigator, will be qualified to land at such airports and will comply with Federal Aviation Administration (“FAA”) mandates for Required Navigation Performance and Automatic Dependent Surveillance-Broadcast navigation. IS&S believes this will further increase the demand for the Company’s products. The Company’s FMS/FPDS product line is designed for new production and retrofit applications in general aviation, commercial air transport and military transport aircraft. In addition, the Company offers what we believe to be a state-of-the-art integrated standby unit, integrating the full functionality of the primary and navigation displays into a small backup-powered unit. This integrated standby unit builds on the Company’s legacy air data computer to form a complete next-generation cockpit display and navigation upgrade offering to the commercial and military markets.

The Company has developed and received certification from the FAA on its NextGen Flight Deck featuring its ThrustSense® Integrated PT6 Autothrottle (“ThrustSense® Autothrottle”) for retrofit in the Pilatus PC 12. The NextGen Flight Deck features Primary Flight and Multi-Function Displays and integrated standby units, as well as an Integrated FMS and EFB System. The innovative avionics suite includes dual flight management systems, autothrottles, synthetic vision and enhanced vision. The NextGen

23

Table of Contents

Flight Deck enhanced avionics suite is available for integration into other business aircraft with full-authority digital engine control (“FADEC”) and non-FADEC engines.

The Company has developed its FAA-certified ThrustSense® Autothrottle for retrofit in the King Air, dual turbo prop PT6 powered aircraft. The ThrustSense® Autothrottle is designed to automate power management for speed and power control including go-around. ThrustSense® Autothrottle also ensures aircraft envelope protection and engine protection during all phases of flight, thereby reducing pilot workload and increasing safety. The Company has signed a multi-year agreement with Textron to supply ThrustSense® Autothrottle on the King Air 360 and King Air 260. ThrustSense® Autothrottle is also available for retrofit on King Air aircraft through Textron service centers and third-party service centers. The Company has also developed an FAA-certified safety mode feature for its King Air ThrustSense® Autothrottle, LifeGuard™, which provides critical Vmca protection that proportionally reduces engine power to maintain directional control during an engine-out condition.

The Company sells to both the OEM and the retrofit markets. Customers include various OEMs, commercial air transport carriers and corporate/general aviation companies, DoD and its commercial contractors, aircraft operators, aircraft modification centers, government agencies and foreign militaries. Occasionally, IS&S sells its products directly to DoD; however, the Company sells its products primarily to commercial customers for end use in DoD programs. Sales to defense contractors are generally made on commercial terms, although some of the termination and other provisions of government contracts are applicable to these contracts. The Company’s retrofit projects are generally pursuant to either a direct contract with a customer or a subcontract with a general contractor to a customer (including government agencies).

In June 2023, the Company entered into an Asset Purchase and License Agreement (as amended, the “Honeywell Agreement”) with Honeywell International, Inc. (“Honeywell”) pursuant to which Honeywell sold, assigned or licensed certain assets related to its inertial, communication and navigation product lines, including a sale of certain inventory, equipment and customer-related documents, an assignment of certain contracts and a grant of exclusive and non-exclusive licenses to use certain Honeywell intellectual property related to its inertial, communication and navigation product lines to repair, overhaul, manufacture sell, import, export and distribute certain products to the Company for cash consideration of $35.9 million. On July 22, 2024, the Company entered into Amendment No. 3 to the Honeywell Agreement (the “Amendment”). Pursuant to the Amendment, Honeywell sold, assigned or licensed to the Company certain additional assets related to its communication and navigation product lines, including a sale of certain inventory and customer-related documents; an assignment of certain contracts; and a grant of exclusive and non-exclusive licenses to use certain Honeywell intellectual property related to its communication and navigation product lines to manufacture, upgrade and repair certain additional products for consideration of $4.2 million in cash.

The exclusive licensing of these product lines from Honeywell enhances the Company’s current offerings in the air transport, military and business aviation markets. In addition, there are potential cost synergies from better utilization of the Company’s skilled engineering team and its existing operational capacity. The Company believes the Honeywell Agreement will help to accelerate the Company’s growth and enhance its global reputation for delivering some of the industry’s best price-for-performance value propositions.

Cost of sales related to product and service sales comprises materials, components and third-party avionics purchased from suppliers, direct labor and overhead costs. Many of the components are standard, although certain parts are manufactured to meet IS&S specifications. The overhead portion of cost of sales primarily comprises salaries and benefits, building occupancy costs, supplies and outside service costs related to production, purchasing, material control and quality control. Cost of sales also includes warranty costs.

Cost of sales related to Engineering Development Contracts (“EDC”) sales comprises engineering labor, consulting services and other costs associated with specific design and development projects. These costs are incurred pursuant to contractual arrangements and are accounted for typically as contract costs within cost of sales, with the reimbursement accounted for as a sale in accordance with the percentage-of-completion method or completed contract method of accounting. Company funded research and development (“R&D”) expenditures relate to internally-funded efforts for the development of new products and the improvement of existing products. These costs are expensed as incurred and reported as R&D expenses. The Company intends to continue investing in the development of new products that complement current product offerings and to expense associated R&D costs as they are incurred.

Selling, general and administrative expenses consist of sales, marketing, business development, professional services, salaries and benefits for executive and administrative personnel, facility costs, recruiting, legal, accounting and other general corporate expenses.

The Company sells its products to agencies of the United States and foreign governments, aircraft operators, aircraft modification centers and OEMs. Customers have been and may continue to be affected by changes in economic conditions both in the United States and abroad. Such changes may cause customers to curtail or delay their spending on both new and existing aircraft. Factors that can impact general economic conditions and the level of spending by customers include, but are not limited to, general levels of consumer spending, increases in fuel and energy costs, conditions in the real estate and mortgage markets, labor and healthcare costs, access to credit, consumer confidence, inflation, public health crises and pandemics, and other macroeconomic factors that affect spending behavior. Furthermore, spending by government agencies may be reduced in the future. If customers curtail or delay their spending or are forced to declare bankruptcy or liquidate their operations because of adverse economic conditions, the Company’s revenues and results of operations would be affected adversely. For example, in the 2020 fiscal year, certain of the Company’s customers temporarily suspended product deliveries as a result of the COVID-19 pandemic, and while these deliveries subsequently resumed, there is a possibility that similar pandemics will result in other suspensions, delays or order cancellations by the Company’s customers or suppliers.

Environmental, Social and Governance Considerations

​

In recent years, environmental, social and governance (“ESG”) issues have become an increasing area of focus for some of our shareholders, customers and suppliers. Management and the Company’s Board of Directors are committed to identifying, assessing and understanding the potential impact of ESG issues and related risks on the Company’s business model, as well as potential areas of improvement.

​

We are committed to recruiting, motivating and developing a diversity of talent. We are an equal opportunity employer and a Vietnam Era Veterans’ Readjustment Assistance Act federal contractor. All qualified applicants receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability status, protected veteran status, or any other characteristic protected by law.

​

The nature of our business also supports long-term sustainability. Historically, a majority of the Company’s sales have come from the retrofit market, in which the Company, by making upgrades to improve the functionality and safety of existing machinery, facilitates the re-use and recycling of aircraft and equipment that might otherwise be scrapped as obsolete. The Company’s GPS receivers also facilitate reduced carbon footprint navigation. The Company also plans to enhance its focus on the environmental impact of its operations.

​

Critical Accounting Policies and Estimates

The discussion and analysis of financial condition and consolidated results of operations are based upon the Company’s condensed consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The preparation of these condensed consolidated financial statements requires estimates and assumptions that affect the reported amounts of assets, liabilities, sales and expenses and related disclosure of contingent assets and liabilities. Management has determined that the most critical accounting policies and estimates are those related to revenue recognition, inventory valuation and valuation of tangible and intangible assets acquired. On an ongoing basis, the Company’s management evaluates its estimates based upon historical experience and various other assumptions that it believes to be reasonable in 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.

The Company believes that its critical accounting policies affect its more significant estimates and judgments used in the preparation of its condensed consolidated financial statements. The Annual Report on Form 10-K for the fiscal year ended September 30, 2023 contains a discussion of these critical accounting policies. There have been no material changes in the Company’s critical accounting policies since September 30, 2023. See also Note 1 to the unaudited condensed consolidated financial statements for the three- and nine-month periods ended June 30, 2024 as set forth herein.

The Company’s principal source of liquidity has been cash flows from current year operations and cash accumulated from prior years’ operations, supplemented with borrowings under our term loan and revolving credit facility. Cash is used principally to finance inventory, accounts receivable, contract assets, payroll, debt service and acquisitions, as well as the Company’s known contractual and other commitments (including those described in Note 8, “Leases”). The Company’s existing cash balances and anticipated cash flows from operations, together with borrowings under our term loan and revolving credit facility, are expected to be adequate to satisfy the Company’s liquidity needs for at least the next 12 months. Apart from what has been disclosed in this Management’s Discussion and Analysis, management is not aware of any trends, events or uncertainties that have had or are likely to have a material impact on our liquidity, financial condition and capital resources.

The declaration and payment of any dividend in the future will be at the discretion of the Company’s Board of Directors.

Debt Facility

On December 19, 2023, the Company and PNC entered into an Amendment to Loan Documents (the “Restated Loan Amendment”) and a corresponding Amended and Restated Revolving Line of Credit Note (“Restated Line of Credit Note”) and Amended and Restated Line of Credit and Investment Sweep Rider (the “Restated Rider”), to increase the aggregate principal amount available under the Company’s senior secured revolving line of credit from $10,000,000 to $30,000,000 and extend the maturity date until December 19, 2028.

The shares will be offered and sold pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-267595), which was declared effective by the SEC on October 14, 2022. The Company filed a prospectus supplement, dated September 22, 2023, with the SEC in connection with the offer and sale of the shares. Subject to the terms and conditions of the ATM Sales Agreement, the Sales Agent will use commercially reasonable efforts to sell shares of the Company’s common stock from time to time, based upon the Company’s instructions.

During the year ended September 30, 2023 and the three- and nine-month periods ended June 30, 2024, we did not sell any shares of common stock under the ATM Sales Agreement.

Summary

Future capital requirements depend upon numerous factors, including market acceptance of the Company’s products, the timing and rate of expansion of business, acquisitions, joint ventures and other factors. IS&S has experienced increases in expenditures since its inception and anticipates that expenditures will continue in the foreseeable future. The Company believes that its cash and cash equivalents will provide sufficient capital to fund operations for at least the next twelve months. However, the Company may need to develop and introduce new or enhanced products, respond to competitive pressures, invest in or acquire businesses or technologies, or

30

Table of Contents

respond to unanticipated requirements or developments. If insufficient funds are available, the Company may not be able to introduce new products or compete effectively.

Backlog

Backlog represents the value of contracts and purchase orders, less the revenue recognized to date on those contracts and purchase orders. Backlog activity for the nine-month period ended June 30, 2024:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three Months Ended | ​ | Nine Months Ended | ​
​ |  | June 30, 2024 |
Backlog, beginning of period | ​ | $ | 10,432,682 | ​ | $ | 13,450,881 | ​
Plus: bookings during period, net | ​ |  | 10,599,505 | ​ |  | 27,628,885 | ​
Less: sales recognized during period | ​ |  | (11,765,635) | ​ |  | (31,813,214) | ​
Backlog, end of period | ​ | $ | 9,266,552 | ​ | $ | 9,266,552 | ​

​

At June 30, 2024, the majority of the Company’s backlog is expected to be filled within the next twelve months. To the extent new business orders do not continue to equal or exceed sales recognized in the future from the Company’s existing backlog, future operating results may be impacted negatively.

Off-Balance Sheet Arrangements

The Company has no relationships with unconsolidated entities or financial partnerships, such as Special Purpose Entities or Variable Interest Entities, established for the purpose of facilitating off-balance sheet arrangements or other limited purposes.

​

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The Company’s operations are exposed to market risks primarily as a result of changes in interest rates. The Company does not use derivative financial instruments for speculative or trading purposes. The Company’s exposure to market risk for changes in interest rates relates to its cash equivalents. The Company’s cash equivalents consist of funds invested in money market accounts, which bear interest at a variable rate. The Company does not participate in interest rate hedging. Cash balances are maintained with two major banks. Balances on deposit with certain money market accounts and operating accounts may exceed the Federal Deposit Insurance Corporation limits. A change in interest rates earned on the cash equivalents would impact interest income and cash flows but would not impact the fair market value of the related underlying instruments. Assuming that the balances during the nine-month period ended June 30, 2024 were to remain constant and the Company did not act to alter the existing interest rate sensitivity, a hypothetical 1% increase in variable interest rates would have affected interest income by approximately $15,618 with a resulting impact on cash flows of approximately $15,618 for the nine-month period ended June 30, 2024.
