Organization and Summary of Significant Accounting Policies Organization We provide private-label contract manufacturing services to companies that market and distribute vitamins, minerals, herbs, and other nutritional supplements, as well as other health care products, to consumers both within and outside the U.S. We also seek to commercialize our patent and trademark estate related to the ingredient known as beta-alanine sold under our CarnoSyn® and SR CarnoSyn® tradenames through direct raw material sales and various license and similar arrangements. Subsidiaries On January 22, 1999, September 1999, Principles of Consolidation The consolidated financial statements include the accounts of Natural Alternatives International, Inc. (NAI) and our wholly-owned subsidiary, NAIE. All intercompany accounts and transactions have been eliminated. The functional currency of NAIE, our foreign subsidiary, is the U.S. Dollar. Certain accounts of NAIE have been translated at either current or historical exchange rates, as appropriate, with gains and losses included in the consolidated statements of operations.

Accounts Receivable We perform ongoing credit evaluations of our customers and adjust credit limits based on payment history and customer credit-worthiness. An allowance for estimated doubtful accounts is maintained based on historical experience, including identified customer credit issues. We monitor collections regularly and adjust the allowance for doubtful accounts as necessary to recognize any changes in credit exposure. Upon conclusion that a receivable is uncollectible, we record the respective amount as a charge against allowance for doubtful accounts. To date, such doubtful accounts reserves, in the aggregate, have been adequate to cover collection losses. Customer Deposits For certain customers we have contract terms where the customer pays a certain portion of their orders as prepayment. We treat this as a customer deposit liability and do not June 30, 2021 $1.7 June 30, 2020 $0.1 Inventories We operate primarily as a private-label contract manufacturer.

This transfer occurs when the product is shipped, or in some cases, when the product is delivered to the customer. 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. Except for product defects, no June 30, 2021, no We have an Exclusive Manufacturing Agreement with The Juice Plus+ Company LLC (“Juice Plus+”) through August 6, 2025. 24 $1.6 June 30, 2021, $1.6 June 30, 2020, We currently own certain U.S. patents, and each patent's corresponding foreign patent applications.

June 30, 2021 $0.1 To determine our quarterly provision for income taxes, we use an estimated annual effective tax rate that is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions to which we are subject. Certain significant or unusual items are separately recognized as discrete items in the quarter in which they occur and can be a source of variability in the effective tax rate from quarter to quarter. We recognize interest and penalties related to uncertain tax positions, if any, as an income tax expense. 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 Income (Loss) per Common Share We compute basic net income per common share using the weighted average number of common shares outstanding during the period, 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 income per common share as follows (in thousands, except per share data): For the Years Ended June 30, 2021 2020 Numerator Net income (loss) $ 10,768 $ (1,645 ) Denominator Basic weighted average common shares outstanding 6,291 6,695 Dilutive effect of stock options and restricted stock shares 88 — Diluted weighted average common shares outstanding 6,379 6,695 Basic net income (loss) per common share $ 1.71 $ (0.25 ) Diluted net income (loss) per common share $ 1.69 $ (0.25 ) During the year ended June 30, 2021, 22,500 52,108 In periods where we have a net loss, stock options and restricted stock are excluded from our calculation of diluted net income (loss) per common share, as their inclusion would have an antidilutive effect.

For contracts entered into on or after that effective date, at the inception of a contract we assess whether the contract is, or contains, a lease. Our assessment is based on: ( 1 2 3 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, 2021, 6.3 3.24%. June 30, 2020, 7.2 3.24%. 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 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. Lease expense for operating leases consists of the lease payments plus any initial direct costs, primarily brokerage commissions, and is recognized on a straight-line basis over the lease term. Included in lease expense are any variable lease payments incurred in the period that were not We have elected not 12 not

Certain significant or unusual items are separately recognized as discrete items in the quarter in which they occur and can be a source of variability in the effective tax rate from quarter to quarter. We recognize interest and penalties related to uncertain tax positions, if any, as an income tax expense. 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.
