We amortize leasehold improvements using the straight-line method over the shorter of the useful life of the improvement or the term of the lease. Maintenance and repairs are expensed as incurred. Significant expenditures that increase economic useful lives of property or equipment are capitalized and expensed over the useful life of such expenditure.

This transfer occurs when the product is shipped, or in some cases, when the product is delivered to the customer. We recognize revenue in certain circumstances before delivery to the customer has occurred (commonly referred to as bill-and-hold transactions). Products sold under bill-and-hold arrangements are recorded as revenue when risk of ownership has been transferred to the customer, but the product has not We provide early payment discounts to certain customers. Based on historical payment trends, we expect that these customers will take advantage of these early payment discounts. The cost of these discounts is reported as a reduction to the transaction price. If the actual discounts differ from those estimated, the difference is also reported as a change in the transaction price. We require prepayment from certain customers. We record any payments received in advance of contracts fulfillment as a contract liability and classified as customer deposits on the consolidated balance sheet. Contract liabilities and revenue recognized were as follows (in thousands): June 30, 2023 Additions Revenue Recognized Customer Refunds June 30, 2024 Contract Liabilities (Customer Deposits) $ 317 $ 2,500 $ (2,515 ) $ — $ 302 June 30, 2022 Additions Revenue Recognized Customer Refunds June 30, 2023 Contract Liabilities (Customer Deposits) $ 140 $ 317 $ (137 ) $ (3 ) $ 317 Except for product defects, no June 30, 2024 We currently own certain U.S. patents, and each patent’s corresponding foreign patent applications.

We record valuation allowances to reduce our deferred tax assets to an amount that we believe is more likely than not not June 30, 2024 no Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are measured and recorded using enacted tax rates for each of the jurisdictions in which we operate, and adjusted using the tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income or expense in the period that includes the enactment date.

Use of Estimates Our management has made a number of estimates and assumptions relating to the reporting of assets and liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities to prepare these consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP). Actual results could differ from those estimates and our assumptions may Net (Loss) Income per Common Share We compute basic net (loss) income per common share using the weighted average number of common shares outstanding during the year, and diluted net income per common share using the additional dilutive effect of all dilutive securities. The dilutive impact of stock options and restricted shares account for the additional weighted average shares of common stock outstanding for our diluted net income per common share computation. We calculated basic and diluted net (loss) income per common share as follows (in thousands, except per share data): For the Years Ended June 30, 2024 2023 Numerator Net (loss) income $ (7,217 ) $ 2,522 Denominator Basic weighted average common shares outstanding 5,871 5,863 Dilutive effect of stock options and restricted stock shares — 14 Diluted weighted average common shares outstanding 5,871 5,878 Basic net (loss) income per common share $ (1.23 ) $ 0.43 Diluted net (loss) income per common share $ (1.23 ) $ 0.43 We exclude the impact of restricted stock from the calculation of diluted net loss per common share in periods where we have a net loss or when their inclusion would be antidilutive. During the year ended June 30, 2024 June 30, 2023 Concentrations of Credit Risk Financial instruments that subject us to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We place our cash and cash equivalents with highly rated financial institutions. Credit risk with respect to receivables is primarily concentrated with our three June 30, 2024 June 30, 2023 Additionally, amounts due related to our beta-alanine raw material sales were 4.4% of gross accounts receivable at June 30, 2024 June 30, 2023

Lessee, Operating Leases [Text Block]	D. Leases We currently lease our Vista, California and Lugano, Switzerland product manufacturing and support facilities. At the inception of a contract, we assess whether the contract is, or contains, a lease. Our assessment is based on: ( 1 2 3 On July 18, 2023, ten five April 1, 2024. two five not On January 26, 2024, 9 8 April 30, 2024. January 22, 2024, April 1, 2024 June 30, 2026. Leases are classified as either finance leases or operating leases. A lease must be classified as a finance lease if any of the following criteria are met: the lease transfers ownership of the asset by the end of the lease term, the lease contains an option to purchase the asset that is reasonably certain to be exercised, the lease term is for a major part of the remaining useful life of the asset, or the present value of the lease payments equals or exceeds substantially all of the fair value of the asset. A lease is classified as an operating lease if it does not no June 30, 2024 June 30, 2023 For all leases at the lease commencement date, a right-of-use asset and a lease liability are recognized. The right-of-use asset represents the right to use the leased asset for the lease term. The lease liability represents the present value of the lease payments under the lease. The right-of-use asset is initially measured at cost, which primarily comprises the initial amount of the lease liability, plus any initial direct costs incurred, consisting mainly of brokerage commissions, less any lease incentives received. All right-of-use assets are reviewed for impairment. The lease liability is initially measured at the present value of the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, our secured incremental borrowing rate for the same term as the underlying lease. For our real estate and other operating leases, we use our secured incremental borrowing rate. Lease payments included in the measurement of the lease liability comprise the following: the fixed noncancelable lease payments, payments for optional renewal periods where it is reasonably certain the renewal period will be exercised, and payments for early termination options unless it is reasonably certain the lease will not not Some of our manufacturing leases contain variable lease payments, including payments based on an index or rate. Variable lease payments based on an index or rate are initially measured using the index or rate in effect at lease commencement and separated into lease and non-lease components based on the initial amount stated in the lease or standalone selling prices. Lease components are included in the measurement of the initial lease liability. Additional payments based on the change in an index or rate, or payments based on a change in our portion of the operating expenses, including real estate taxes and insurance, are recorded as a period expense when incurred. Lease modifications result in remeasurement of the lease liability.
