NEUROONE MEDICAL TECHNOLOGIES Corp

NOTE 1 – Description of Business and Basis of Presentation

NeuroOne Medical Technologies Corporation (the “Company” or “NeuroOne”), a Delaware corporation, is a medical technology company focused on the development and commercialization of thin film electrode for continuous electroencephalogram (“cEEG”) and stereoelectrocencephalography (“sEEG”) recording, monitoring, ablation and stimulation solutions to diagnose and treat patients with epilepsy, trigeminal neuralgia, Parkinson’s disease, dystonia, essential tremors, chronic pain due to failed back surgeries and other pain-related neurological disorders. The Company is also developing the capability to use its sEEG electrode technology to deliver drugs or gene therapy while being able to record activity before, during, and after delivery.

The Company has received 510(k) clearance from the United States (“U.S.”) Food and Drug Administration (“FDA”) for four of its devices: (i) its Evo cortical electrode technology for recording, monitoring, and stimulating brain tissue for up to 30 days (“Evo Cortical”), (ii) its Evo® sEEG electrode technology for temporary (less than 30 days) use with recording, monitoring, and stimulation equipment for the recording, monitoring, and stimulation of electrical signals at the subsurface level of the brain (“Evo sEEG”); (iii) its OneRF ablation system for creation of radiofrequency lesions in nervous tissue for functional neurosurgical procedures (the “OneRF Ablation System”) and (iv) our OneRF TN ablation system for use in procedures to create radiofrequency (RF) lesions for the treatment of pain, or for lesioning nerve tissue for functional neurosurgical procedures (“OneRF TN Ablation System”, together with the Evo Cortical, Evo sEEG, and OneRF Ablation System, the “Commercialized Products”). The Company has a distribution agreement with Zimmer, Inc. (“Zimmer”) providing Zimmer with a license to commercialize and distribute the Evo Cortical, Evo sEEG, and OneRF Ablation System in the brain. The Company initiated a limited market release of its OneRF TN Ablation System in December 2025 and completed the limited market release in March 2026. The Company’s other products and indications are still under development.

The Company is based in Eden Prairie, Minnesota.

Global Economic Conditions

Generally, worldwide economic conditions remain uncertain, particularly due to the conflicts between Russia and Ukraine and in the Middle East, disruptions in the banking system and financial markets, and increased inflation. The general economic and capital market conditions both in the U.S. and worldwide, have been volatile in the past and at times have adversely affected the Company’s access to capital and increased the cost of capital. The capital and credit markets may not be available to support future capital raising activity on favorable terms or at all. If economic conditions continue to decline, the Company’s future cost of equity or debt capital and access to the capital markets could be adversely affected. The Company has experienced minor price increases from our suppliers related to tariffs on imported goods and may experience additional price increases.

The Company’s operating results could be materially impacted by changes in the overall macroeconomic environment and other economic factors. Changes in economic conditions, supply chain constraints, logistics challenges, labor shortages, the conflicts in Ukraine and the Middle East, disruptions in the banking system and financial markets, and steps taken by governments and central banks, have led to higher inflation, which has led to an increase in costs and has caused changes in fiscal and monetary policy, including increased interest rates. The Company expects to submit a request for a tariff refund for minor tariffs paid by the Company to the U.S. government under the International Emergency Economic Powers Act, but the timing and amount of cash receipt pursuant to such future submission remains uncertain. We will continue to monitor guidance issued regarding the refund process.

Basis of presentation

The accompanying unaudited condensed financial statements have been prepared by the Company, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. The condensed financial statements may not include all disclosures required by U.S. GAAP; however, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited condensed financial statements should be read in conjunction with the audited financial statements and the notes thereto for the year ended September 30, 2025 included in the Company’s Annual Report on Form 10-K. The condensed balance sheet at September 30, 2025 was derived from the audited financial statements of the Company.

In the opinion of management, all adjustments, consisting of only normal recurring adjustments that are necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, have been made. The results of operations for the interim periods are not necessarily indicative of the operating results for the full fiscal year or any future periods.

Reverse Stock Split

On April 14, 2026, the Company filed an amendment to its Amended and Restated Certificate of Incorporation, as amended and/or restated from time to time, to effectuate a reverse stock split of the Company’s issued and outstanding shares of common stock, par value $0.001 per share (the “Reverse Stock Split”). Trading of the common stock on The Nasdaq Capital Market commenced on a split-adjusted basis at market open on April 16, 2026. All amounts in the condensed financial statements have been retroactively adjusted to reflect the Reverse Stock Split.

As a result of the Reverse Stock Split, every 6 shares of the Company’s common stock issued or outstanding was automatically reclassified into one validly issued, fully-paid and non-assessable new share of common stock, subject to the treatment of fractional shares as described below, without any action on the part of the holders. Proportional adjustments were made to the number of shares of common stock awarded and available for issuance under the Company’s equity incentive plans, as well as the exercise price and the number of shares issuable upon the exercise or conversion of the Company’s outstanding stock options and other equity securities under the Company’s equity incentive plans. All outstanding warrants were also adjusted in accordance with their terms. The shares of common stock outstanding following the Reverse Stock Split will remain fully paid and non-assessable. The Reverse Stock Split did not affect the number of authorized shares of common stock or the par value per share of the common stock.

No fractional shares were issued in connection with the Reverse Stock Split. Stockholders who would otherwise be entitled to receive fractional shares as a result of the Reverse Stock Split were automatically entitled to receive a cash payment equal to the market value of the fractional share. The Reverse Stock Split affected all stockholders uniformly and did not alter any stockholder’s relative interest in the Company’s equity securities, except for any adjustments for fractional shares.

NOTE 2 - Going Concern

The accompanying condensed financial statements have been prepared on the basis that the Company will continue as a going concern. The Company has incurred losses since inception, negative cash flows from operations, and an accumulated deficit of $82.1 million as of March 31, 2026. To date, the Company’s revenues have not been sufficient to cover its full operating costs, and as such, it has been dependent on funding operations through the issuance of debt and sale of equity securities which previously resulted in substantial doubt regarding the Company’s ability to continue as a going concern. As of March 31, 2026, the Company had $2.8 million in cash and cash equivalents. The Company believes its current available cash and cash equivalents coupled with the anticipated increase in product revenues from minimum purchases and improved gross margins under the distribution agreement with Zimmer (See “Note 7– Zimmer Distribution Agreement and Other Product Revenue”) and forecasted operating expense reductions, will be sufficient to fund the Company’s operations through September 2026. The raising of additional funds is not solely within the control of the Company. These factors raise substantial doubt about the Company’s ability to continue as a going concern. The condensed financial statements do not include any adjustments that might result from the outcome of this condition. If the Company is unable to raise additional funds, or the Company’s anticipated operating results are not achieved, management believes planned expenditures may need to be reduced in order to extend the time period that existing resources can fund the Company’s operations.

The Company intends to fund ongoing activities by utilizing its current cash and cash equivalents on hand, from product and collaborations revenue and by raising additional capital through equity or debt financing. If management is unable to obtain the necessary capital, it may have a material adverse effect on the operations of the Company and the development of its technology, or the Company may have to cease operations altogether.

NOTE 3 – Summary of Significant Accounting Policies

Management’s Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP 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 period. Actual results could differ from those estimates.

Segment Information

Operating segments are components of an enterprise for which separate financial information is available and are evaluated regularly by the Company’s chief operating decision maker (“CODM”) in deciding how to allocate resources and assessing performance. The Company’s CODM is its Chief Executive Officer. The Company’s Chief Executive Officer views the Company’s operations and manages its business inone operating segment. See “Note 14 – Segment Reporting”.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original contractual maturity on date of purchase of less than or equal to three months to be classified and presented as cash equivalents on the balance sheets. Cash equivalents are stated at cost, which approximates fair value. The Company’s cash and cash equivalents may include demand deposit accounts with large financial institutions, institutional money market funds, U.S. Treasury securities, and corporate notes and bonds. The Company monitors the creditworthiness of the financial institutions, institutional money market funds, and corporations in which the Company invests its surplus funds. The Company has experienced no credit losses from its cash and cash equivalent investments.

Revenue Recognition

The Company entered into a development and distribution agreement which has current and future revenue recognition implications. See “Note 7 – Zimmer Distribution Agreement and Other Product Revenue.”

In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under its agreements, the Company performs the following steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated selling prices; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in Accounting Standards Codification (“ASC”) Topic 606,Revenue from Contracts with Customers (“ASC 606”). Performance obligations may include license rights, development services, and services associated with regulatory submission and approval processes. Significant management judgment is required to determine the level of effort required under an arrangement and the period over which the Company expects to complete its performance obligations under the arrangement. If the Company cannot reasonably estimate when its performance obligations are either completed or become inconsequential, then revenue recognition is deferred until the Company can reasonably make such estimates. Revenue is then recognized over the remaining estimated period of performance using the cumulative catch-up method.

Product Revenue

Revenues from product sales are recognized when control of the promised goods or services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. At the inception of each customer contract, performance obligations are identified and the total transaction price is allocated to the performance obligations.

Cost of Product Revenue

Cost of product revenue consists of the manufacturing and materials costs incurred by the Company’s third-party contract manufacturers in connection with OneRF Brain Ablation System and the OneRF® Trigeminal Nerve Ablation System (the “OneRF Products”), strip and grid cortical electrodes (the “Strip/Grid Products”), depth electrodes (“sEEG Products”) and outside supplier materials costs in connection with the electrode cable assembly products (“Electrode Cable Assembly Products”) when sold. In addition, cost of product revenue includes royalty fees incurred in connection with the Company’s license agreements as well as valuation adjustments for excess or obsolete inventory.

As part of the accounting for collaboration arrangements, the Company must develop assumptions that require judgment to determine the stand-alone selling price of each performance obligation identified in the contract. The Company uses key assumptions to determine the stand-alone selling price, which may include forecasted revenues, development timelines, reimbursement rates for personnel costs, discount rates and probabilities of technical and regulatory success. The Company allocates the total transaction price to each performance obligation based on the estimated relative stand-alone selling prices of the promised goods or service underlying each performance obligation.

Licenses of intellectual property: If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from non-refundable, up-front fees allocated to the license when the license is transferred to the customer, and the customer can use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

Milestone payments: At the inception of each arrangement that includes milestone payments, the Company evaluates whether the milestones are considered probable of being achieved and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal will not occur, the value of the associated milestone (such as a regulatory submission) is included in the transaction price. Milestone payments that are not within the control of the Company, such as approvals from regulators, are not considered probable of being achieved until those approvals are received. When the Company’s assessment of probability of achievement changes and variable consideration becomes probable, any additional estimated consideration is allocated to each performance obligation based on the estimated relative stand-alone selling prices of the promised goods or service underlying each performance obligation and recorded in license revenues based upon when the customer obtains control of each element.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company recognizes revenue at the later of (a) when the related sales occur, or (b) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

Warrant Liability

The Company issued warrants in connection with its 2024 Private Placement. See “Note 12– Stockholders’ Equity”. The Company accounts for these warrants as a liability at fair value when warrant pricing protection provisions are not available to other common stockholders. Additionally, issuance costs associated with the warrant liability are expensed as incurred and reflected as a financing cost in the accompanying condensed statements of operations. The Company adjusts the liability for changes in fair value until the earlier of the exercise or expiration of the warrants for any period when pricing protections remain in place. Any future change in the fair value of the warrant liability is recognized in the condensed statements of operations under the fair value change in warrant liability line item.

Fair Value of Financial Instruments

The Company’s accounting for fair value measurements of assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring or nonrecurring basis adheres to the Financial Accounting Standards Board (“FASB”) fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:

As of March 31, 2026 and September 30, 2025, the fair values of cash, cash equivalents, accounts receivable, inventory, prepaid expenses, deferred offering costs, accounts payable and accrued expenses and other liabilities approximated their carrying values because of the short-term nature of these assets or liabilities. The fair value of the warrant liability was based on Level 3 inputs as well as the Company’s underlying stock price and associated volatility, expected term of the warrants and market interest rates. There were no transfers between fair value hierarchy levels during the three and six months ended March 31, 2026 and 2025.

The fair value of financial instruments measured on a recurring basis is as follows:

The following table provides a roll-forward of the warrant liability measured at fair value on a recurring basis using unobservable level 3 inputs for the six months ended March 31, 2026 and 2025, respectively.

Intellectual Property

The Company has entered into two licensing agreements with major research institutions, which allow for access to certain patented technology and know-how. Payments under those agreements are capitalized and amortized to selling, general and administrative expense over the expected useful life of the acquired technology.

Property and Equipment

Property and equipment is recorded at cost and reduced by accumulated depreciation. Depreciation expense is recognized over the estimated useful lives of the assets using the straight-line method. The estimated useful life for equipment and furniture ranges from three tofive years. Tangible assets acquired for research and development activities and that have alternative use are capitalized over the useful life of the acquired asset. Estimated useful lives are periodically reviewed, and, when appropriate, changes are made prospectively. When certain events or changes in operating conditions occur, asset lives may be adjusted and an impairment assessment may be performed on the recoverability of the carrying amounts. Maintenance and repairs are charged directly to expense as incurred.

Impairment of Long-Lived Assets

The Company evaluates its long-lived assets, which consist of licensed intellectual property, property and equipment and right-of-use assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. The Company assesses the recoverability of long-lived assets by determining whether the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the asset is considered to be impaired, the amount of impairment is measured as the difference between the carrying value and the fair value of the impaired asset.

Accounts Receivable and Allowances for Credit Losses

The Company records a provision for credit losses, when appropriate, based on historical experience, current conditions and reasonable supportable forecasts. In estimating the allowance for credit losses, the Company considers, among other factors, the estimate of credit losses over the remaining expected life of the asset, primarily using historical experience and current economic conditions that could affect the collectability of the balances in the future. Account balances are charged off against the allowance when the Company believes that it is probable that the receivable will not be recovered. Actual write-offs may be in excess of the Company’s estimated allowance. The Company has not incurred any bad debt expense to date and no allowance for credit losses has been recorded during the periods presented.

Inventory

Inventory is stated at the lower of cost (using the first-in, first-out “FIFO” method) or net realizable value. The Company calculates inventory valuation adjustments for excess and obsolete inventory, when appropriate, based on current inventory levels, movement, expected useful lives, and estimated future demand of the products and spare parts. The Company’s inventory is currently comprised of its commercialized product components, work-in-process and finished goods. The commercialized products are produced by a third-party contract manufacturer and electrode cable assembly components are obtained from outside suppliers.

Research and Development Costs

Research and development costs are charged to expense as incurred. Research and development expenses comprise of costs incurred in performing research and development activities, including compensation and benefits for research and development employees (including stock-based compensation), overhead expenses, cost of laboratory supplies, clinical trial and related clinical manufacturing expenses, costs related to regulatory operations, fees paid to consultants and other outside expenses. Non-refundable advance payments for goods and services that will be used in future research and development activities are expensed when the activity is performed or when the goods have been received, rather than when payment is made, in accordance with ASC 730,Research and Development.

Advertising Expense

Advertising expense is charged to selling, general and administrative expenses during the period that it is incurred. Total advertising expense amounted to $58,848 and $119,399 for the three and six months ended March 31, 2026, respectively. Total advertising expense amounted to $45,000 and $83,543 for the three and six months ended March 31, 2025, respectively.

Selling, General and Administrative

Selling, general and administrative expenses consist primarily of personnel-related costs including stock-based compensation for personnel in functions not directly associated with research and development activities. Other significant costs include legal and litigation costs relating to corporate matters, intellectual property costs, professional fees for consultants assisting with financial and administrative matters, and sales and marketing in connection with the commercial sales of the Company’s products.

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with the provisions of ASC 718,Compensation — Stock Compensation(“ASC 718”). Accordingly, compensation costs related to equity instruments granted are recognized at the grant-date fair value over the requisite service period. The Company records forfeitures when they occur. Stock-based compensation arrangements to non-employees are accounted for in accordance with the applicable provisions of ASC 718.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax base and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax asset will not be realized.

Net loss per share

For the Company, basic loss per share of common stock is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period.

Diluted earnings or loss per share of common stock is computed similarly to basic earnings or loss per share except the weighted average shares outstanding are increased to include additional shares from the assumed exercise of any common stock equivalents, if dilutive. The Company’s warrants, stock options, and restricted stock units while outstanding are considered common stock equivalents for this purpose. Diluted earnings or loss per share of common stock is computed utilizing the treasury method for the warrants, stock options and restricted stock units.

The table below presents the computation of basic and diluted loss per share:

The following table presents the computation of weighted average common shares considered in the computation of diluted net loss per share during the three and six months ended March 31,

The following potential common shares were not considered in the computation of basic net loss per share as their effect would have been anti-dilutive for the three and six months ended March 31, 2026 and 2025:

Recent Accounting Pronouncements

In December 2023, the FASB issued Accounting Standards Update (ASU) 2023-09Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances income tax disclosures primarily related to the rate reconciliation and income taxes paid information. This guidance also includes certain other amendments to improve the effectiveness of income tax disclosures. This ASU is effective for fiscal years beginning after December 15, 2024, including interim periods within those fiscal years and should be applied on a prospective basis, with retrospective application permitted. The Company adopted this guidance on October 1, 2025 and the newly adopted guidance will result in additional income tax disclosures in its financial statements.

In November 2024, the FASB issued ASU 2024-03Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This ASU is intended to improve the disclosures related to expenses and provide investors more detailed information about certain types of expenses. This ASU is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the potential impact that this new standard will have on its financial statements and related disclosures.

NOTE 4 – Commitments and Contingencies

WARF License Agreement

The Company has entered into an exclusive start-up company license agreement with the Wisconsin Alumni Research Foundation (“WARF”) for WARF’s neural probe array and thin film micro electrode technology. The Company entered into an Amended and Restated Exclusive Start-up Company License Agreement (the “WARF License”) with WARF on January 21, 2020, which amended and restated in full the prior license agreement between WARF and NeuroOne, LLC, a predecessor of the Company, dated October 1, 2014, as amended on February 22, 2017, March 30, 2019 and September 18, 2019.

The WARF License grants to the Company an exclusive license to make, use and sell, in the United States only, products that employ certain licensed patents for a neural probe array or thin-film micro electrode array and method. The Company agreed to pay WARF a royalty equal to a single-digit percentage of our product sales pursuant to the WARF License, with a minimum annual royalty payment of $150,000 while the WARF License is in effect. If the Company or any of its sublicensees contest the validity of any licensed patent, the royalty rate will be doubled during the pendency of such contest and, if the contested patent is found to be valid and would be infringed by the Company if not for the WARF License, the royalty rate will be tripled for the remaining term of the WARF License.

WARF may terminate the WARF License on 30 days’ written notice if we default on the payments of amounts due to WARF or fail to timely submit development reports, actively pursue our development plan or breach any other covenant in the WARF License and fail to remedy such default in 90 days or in the event of certain bankruptcy events involving us. WARF may also terminate the WARF License if, after royalties earned on sales begin to be paid, such earned royalties cease for more than four calendar quarters. The WARF License otherwise expires by its terms on the date that no valid claims on the patents licensed thereunder remain. The Company expects the latest expiration of a licensed patent to occur in 2030. During the three months ended March 31, 2026 and 2025, $37,500 in royalty fees were incurred related to the WARF License during each of these periods. During the six months ended March 31, 2026 and 2025, $75,000 in royalty fees were incurred during each of these periods related to the WARF License. The royalty fees were reflected as a component of cost of product revenue.

Mayo Agreement

The Company has an exclusive license and development agreement with the Mayo Foundation for Medical Education and Research (“Mayo”) related to certain intellectual property and development services for thin film micro electrode technology (“Mayo Agreement”). If the Company is successful in obtaining regulatory approval, the Company is to pay royalties to Mayo based on a percentage of net sales of products of the licensed technology through the term of the Mayo Agreement, set to expire May 25, 2037. During the three and six months ended March 31, 2026 and 2025, no royalty fees were incurred related to the Mayo Agreement.

Facility Leases

Headquarters Lease

On May 20, 2024, the Company amended its non-cancellable headquarters lease (the “Lease”) with certain landlords (together, the “Landlord”) pursuant to which the Company leases office space located at 7599 Anagram Drive, Eden Prairie, Minnesota (the “Premises”). The Company took possession of the Premises on November 1, 2019, with the term of the Lease ending June 30, 2028, as amended, unless terminated earlier (the “Lease Term”). The base rent for the Premises ranges from $6,410 per month to $7,107 per month by the end of the Lease Term. In addition, as long as the Company is not in default under the Lease, the Company will be entitled to an abatement of its base rent for the first two months of the amended Lease Term beginning in April 2025 and for the last month of the amended Lease Term (June 2028). In addition, the Company pays its pro rata share of the Landlord’s annual operating expenses associated with the Premises.

Los Gatos Lease

In 2021, the Company entered into and commenced a non-cancellable facility lease (the “Los Gatos Lease”), pursuant to which the Company agreed to rent office space for its research and development operations located at 718 University Avenue, Suite #111, Los Gatos, California. The facility space under the Los Gatos Lease is approximately 1,162 square feet. In 2022, the Los Gatos Lease was extended for an additionaltwo years to December 31, 2024. The rent under the extended Los Gatos Lease ranged from $4,453 to $4,632 per month beginning on January 1, 2023. On December 17, 2024, the Los Gatos Lease was extended again for an additionaltwo years to December 31, 2026. The rent under the newly extended Los Gatos Lease ranges from $4,939 to $5,087 per month beginning on January 1, 2025.

During the three and six months ended March 31, 2026, rent expense associated with the facility leases amounted to $69,785 and $140,186, respectively. During the three and six months ended March 31, 2025, rent expense associated with the facility leases amounted to $70,065 and $139,243, respectively.

Supplemental cash flow information related to the operating leases was as follows:

Other Contingencies

In the ordinary course of business, from time to time, the Company may be subject to a broad range of claims and legal proceedings that relate to contractual allegations, patent infringement and other claims. The Company establishes accruals when applicable for matters and commitments which it believes losses are probable and can be reasonably estimated. To date, no loss contingency for such matters and potential commitments have been recorded. Although it is not possible to predict with certainty the outcome of these matters or potential commitments, the Company is of the opinion that the ultimate resolution of these matters and potential commitments will not have a material adverse effect on its results of operations or financial position.

NOTE 6 - Accrued Expenses and Other Liabilities

Accrued expenses and other liabilities consisted of the following:

NOTE 7 – Zimmer Distribution Agreement and Other Product Revenue

On October 25, 2024, the Company entered into the Zimmer Amended and Restated Distribution Agreement (the “Amendment” or “Zimmer Distribution Agreement”) with Zimmer pursuant to which the Company granted Zimmer the exclusive right and license to distribute its OneRF Ablation System for an upfront payment of $3.0 million, with eligibility for an additional $1.0 million payment from Zimmer upon achievement of certain specified net sales milestones.

The Company and Zimmer previously entered into an Exclusive Development and Distribution Agreement related to the sEEG and Strip/Grid Product Systems, which was subsequently amended a couple of times through August 2, 2022( the “EDDA”). The EDDA executed prior to the Amendment granted Zimmer exclusive global rights to distribute the Strip/Grid Products and the Electrode Cable Assembly Products. Additionally, the Company granted Zimmer the exclusive right and license to distribute certain sEEG Products developed by the Company and together with the Strip/Grid Products and Electrode Cable Assembly Products, the “Products”. In addition, under the prior EDDAs, the Company and Zimmer agreed to collaborate with respect to development activities through a joint development committee composed of an equal number of representatives of Zimmer and the Company.

Under the Amendment, Zimmer paid the Company $3.0 million for an exclusive RF Distribution License (the “RF Distribution License” and “License”) for commercialization of its OneRF Ablation System in the brain. Distribution and commercialization of the OneRF® Trigeminal Nerve Ablation System is not covered by the License. In addition, the Company is eligible to receive a future milestone payment of $1.0 million upon reaching a one-time sales volume threshold, but does not anticipate achieving this milestone.

The revised term under the Amendment (the “Term”) began on the effective date of the Amendment and will remain in effect until October 31, 2034. Upon the expiration of the Term, it may be renewed upon the mutual written consent of the parties. The Amended and Restated Exclusive Development and Distribution Agreement may be terminated before the expiration of the Term in accordance with certain terms under the Amendment. In addition, the license rights granted to Zimmer under this Amendment shall be exclusive (i) until September 30, 2032 for the sEEG Products and Strip/Grid Products; and (ii) until October 31, 2034 for the OneRF Ablation System in the brain.

The Amendment was accounted for under the provisions of ASC 606 as a separate contract from the prior EDDAs. In accordance with the provisions under ASC 606, the Company identified the transfer of the RF Distribution License as the sole performance obligation of the RF Distribution License. The distribution rights granted to Zimmer, inclusive of the access to the underlying intellectual property for future production of the OneRF Product if required, was found to have significant standalone functionality as no additional substantive input was required by the Company on a go forward basis. Lastly, ancillary support related to the Amendment was concluded to be a perfunctory obligation and de minimis in terms of required resources.

The transaction price associated with the Amendment was $3.0 million, which was comprised solely of the One RF Exclusivity Fee and was allocated totally to RF Distribution License performance obligation.

Sales Volume Milestone and Payment
