Note 1.

Basis of Financial Statements

 

In the opinion of Greystone Logistics, Inc. (“Greystone” or the “Company”), the accompanying unaudited consolidated financial statements contain all adjustments and reclassifications, which are of a normal recurring nature, necessary to present fairly its financial position as of November 30, 2023, the results of its operations for the six months and three months ended November 30, 2023 and 2022 and its cash flows for the six months ended November 30, 2023 and 2022. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the fiscal year ended May 31, 2023 and the notes thereto included in the Form 10-K for such period. The results of operations for the six months and three months ended November 30, 2023 and 2022 are not necessarily indicative of the results to be expected for the full fiscal year.

 

The unaudited consolidated financial statements of Greystone include its wholly-owned subsidiaries, Greystone Manufacturing, L.L.C. (“GSM”) and Plastic Pallet Production, Inc. (“PPP”), and the variable interest entity, Greystone Real Estate, L.L.C. (“GRE”) for the period from June 1, 2022 through July 29, 2022. All material intercompany accounts and transactions have been eliminated in the unaudited consolidated financial statements.

 

GRE owns two buildings located in Bettendorf, IA, which are occupied by Greystone. GRE is wholly owned by Robert B. Rosene, Jr., a member of Greystone's Board of Directors. Effective July 29, 2022, GRE paid off its mortgage note payable, and in conjunction with the Company's refinancing described in Note 6, GRE was removed from the cross-collateralization agreement. Following these transactions Greystone was no longer determined to be the primary beneficiary of GRE. Accordingly, GRE was deconsolidated from the Greystone consolidated financial statements as of July 29, 2022, resulting in the recognition of a gain in the amount of $569,997. Subsequent to the deconsolidation, the Company entered into a new lease agreement with GRE and recorded right-of-use assets and liabilities for the new lease. See Note 7.

 

Note 2.

Earnings Per Share

 

Basic earnings per share is based on the weighted-average effect of all common shares issued and outstanding and is calculated by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is calculated by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares used in the basic earnings per share calculation plus the number of common shares that would be issued assuming exercise or conversion of all potentially dilutive common shares outstanding.

 

Greystone excludes equity instruments from the calculation of diluted earnings per share if the effect of including such instruments is anti-dilutive. Instruments which have an anti-dilutive effect for the periods ended November 30 are as follows:

Restated and Amended Loan Agreement between Greystone and IBC

On July 29, 2022, Greystone and GSM (each a “Borrower” and together, the “Borrowers”) entered into an Amended and Restated Loan Agreement (“IBC Restated Loan Agreement”) with International Bank of Commerce (“IBC”) that provided for the consolidation of certain term loans and a renewed revolver loan.

 

The IBC term loans require equal monthly payments of principal and interest in such amounts sufficient to amortize the principal balance of the loans over the remaining lives. The monthly payments of principal and interest on the IBC term loans may vary due to changes in the prime rate of interest. As of November 30, 2023, the aggregate payments for the IBC term loans are approximately $254,000 per month.

 

The IBC Restated Loan Agreement, dated July 29, 2022, as amended, provided for IBC to make certain term loans to Greystone to consolidate all existing term loans in the aggregate amount of approximately $2,700,000 and additional funding in the approximate amount of $13,200,000 for the purchase of equipment and renewal of the revolving loan with an increase of $2,000,000 to an aggregate principal amount of $6,000,000 (the “Revolving Loan”), subject to borrowing base limitations. As of November 30, 2023, Greystone’s available revolving loan borrowing capacity was approximately $4,000,000.

 

The IBC Restated Loan Agreement includes customary events of default, including events of default relating to non-payment of principal and other amounts owing under the IBC Restated Loan Agreement from time to time, inaccuracy of representations, violation of covenants, defaults under other agreements, bankruptcy and similar events, the death of a guarantor, certain material adverse changes relating to a Borrower or guarantor, certain judgments or awards against a Borrower, or government action affecting a Borrower’s or guarantor’s ability to perform under the IBC Restated Loan Agreement or the related loan documents. In addition, without prior written consent, Greystone shall not declare or pay any dividends, redemptions, distributions and withdrawals with respect to its equity interest other than distributions to holders of its preferred stock in the aggregate of $500,000 in any fiscal year. Among other things, a default under the IBC Restated Loan Agreement would permit IBC to cease lending funds under the IBC Restated Loan Agreement and require immediate repayment of any outstanding notes with interest and any unpaid accrued fees.

The IBC Restated Loan Agreement is secured by a lien on substantially all assets of the Borrowers. Warren F. Kruger, the Company’s President, CEO and Chairman of the Board and a significant stockholder of Greystone, and Robert B. Rosene, Jr., a member of the Company’s Board of Directors, have provided limited guaranties of the Borrowers’ obligations under the IBC Restated Loan Agreement. Mr. Kruger’s guarantee is limited to 32.4% of all debt obligations to IBC. Mr. Rosene’s limited guaranty is the lesser of (i) $3,500,000 less all amounts paid on the principal amount of the loans after the date of the agreement excluding payments on the revolver and (ii) the amount owed to IBC of the loans outstanding from time to time including accrued interest and fees.

 

Loan Agreement with First Interstate Bank, formerly Great Western Bank

On August 23, 2021, Greystone entered into a loan agreement with First Interstate Bank (“FIB Loan Agreement”) to include prior commercial loans and subsequent loans. GSM is a named guarantor under the FIB Loan Agreement.

 

The FIB Loan Agreement includes customary representations and warranties and affirmative and negative covenants which include (i) requiring the Borrowers to maintain a debt service coverage ratio of 1:25 to 1:00 as of the end of each fiscal year end and debt to tangible net worth ratio of 4:00 to 1:00 as of the end of each fiscal year end with a decrease of 0.50 in the ratio each year thereafter until reaching a minimum ratio of 3:00 to 1:00. In addition, the FIB Loan Agreement provides that Greystone shall not, without prior consent of the bank, incur or assume additional indebtedness or capital leases.

 

The FIB Loan Agreement is secured by a mortgage on one of Greystone’s warehouses.

Operating Leases

Greystone recognized a lease liability for each lease based on the present value of remaining minimum fixed rental payments, using a discount rate that approximates the rate of interest for a collateralized loan over a similar term. A right-of-use asset is recognized for each lease, valued at the lease liability. Minimum fixed rental payments are recognized on a straight-line basis over the life of the lease as costs and expenses on the consolidated statements of income. Variable and short-term rental payments are recognized as costs and expenses as they are incurred.

 

Greystone has three non-cancellable operating leases for (i) equipment with a 52-month term and a 60-month term at a discount rate of 5.40% and (ii) two buildings owned by GRE with a 120-month term, a 60-month renewal option and a discount rate of 6.0%.

Fair Value of Financial Instruments

 

The following methods and assumptions are used in estimating the fair-value disclosures for financial instruments:

 

Debt: The carrying amount of notes with floating rates of interest approximate fair value. Fixed rate notes are valued based on cash flows using estimated rates of comparable notes. The carrying amounts reported on the consolidated balance sheets approximate fair value.

 

Note 11.

Concentrations, Risks and Uncertainties

 

Greystone derived approximately 83% and 73% of its total sales from three customers during the six months ended November 30, 2023 and 2022, respectively. The loss of a material amount of business from one or more of these customers could have a material adverse effect on Greystone.

 

Greystone purchases damaged pallets from its customers at a price based on the value of the raw material content in the pallet. A majority of these purchases, totaling $470,648 for the six months ended November 30, 2023 and $313,050 for the six months ended November 30, 2022, were from one of its major customers.

Forward-Looking Statements and Material Risks

 

This Quarterly Report on Form 10-Q includes certain statements that may be deemed "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical fact, that address activities, events or developments that Greystone expects, believes or anticipates will or may occur in the future, including decreased costs, securing financing, the profitability of Greystone, potential sales of pallets or other possible business developments, are forward-looking statements. Such statements are subject to a number of assumptions, risks and uncertainties. The forward-looking statements contained in this Quarterly Report on Form 10-Q could be affected by any of the following factors: Greystone's prospects could be affected by changes in availability of raw materials, competition, rapid technological change and new legislation regarding environmental matters; Greystone may not be able to secure additional financing necessary to sustain and grow its operations; and a material portion of Greystone's business is and will be dependent upon a few large customers and there is no assurance that Greystone will be able to retain such customers. These risks and other risks that could affect Greystone's business are more fully described in Greystone's Annual Report on Form 10-K for the fiscal year ended May 31, 2023, which was filed with the Securities and Exchange Commission on August 28, 2023, as the same may be updated from time to time. Actual results may vary materially from the forward-looking statements. The results of operations for the six months ended November 30, 2023, are not necessarily indicative of the results for the fiscal year ending May 31, 2024. Greystone undertakes no duty to update any of the forward-looking statements contained in this Quarterly Report on Form 10-Q.

 

Results of Operations

 

General to All Periods

 

The unaudited consolidated statements include Greystone Logistics, Inc., and its two wholly-owned subsidiaries, Greystone Manufacturing, L.L.C. (“GSM”) and Plastic Pallet Production, Inc. (“PPP”). Greystone also consolidated the variable interest entity, Greystone Real Estate, L.L.C. (“GRE”) for the period from June 1, 2022 through July 29, 2022. Effective July 29, 2022, the relationship of Greystone as a beneficiary of GRE ceased to exist. All material intercompany accounts and transactions have been eliminated.

 

Sales

 

Greystone's primary focus is to provide quality plastic pallets to its existing customers while continuing its marketing efforts to broaden its customer base. Greystone's existing customers are primarily located in the United States and engaged in the beverage, pharmaceutical and other industries. Greystone has generated, and plans to continue to generate, interest in its pallets by attending trade shows sponsored by industry segments that would benefit from Greystone's products. Greystone hopes to gain wider product acceptance by marketing the concept that the widespread use of plastic pallets could greatly reduce the destruction of trees on a worldwide basis. Greystone’s marketing is conducted through contract distributors, its President and other employees.

 

 

Personnel

 

Greystone had full-time-equivalents of approximately 181 and 195 and approximately 66 and 40 temporary employees as of November 30, 2023 and 2022 respectfully. Full-time equivalent is a measure based on time worked.

Sales for the six months ended November 30, 2023 were $33,010,707 compared to $31,055,273 for the six months ended November 30, 2022 for an increase of $1,955,434, or 6.3%. The increase in sales for the six months ended November 30, 2023, over the prior period was the result of an approximate 12.8% increase in the quantity of pallets sold somewhat offset by a decrease of approximately 5.3% in the average price per pallet sold. The decrease in the average price per pallet for the current period was the result of price adjustments to reflect decreases in the average cost of raw materials.

 

Greystone had three customers which accounted for approximately 83% in the six months ended November 30, 2023 and 73% in the six months ended November 30, 2022 of sales. Greystone is not able to predict the future needs of these major customers and will continue its efforts to grow sales through the addition of new customers developed through Greystone’s marketing efforts.

 

Cost of Sales

Cost of sales for the six months ended November 30, 2023 was $25,828,480, or 78.2% of sales, compared to $27,369,753, or 88.1% of sales for the six months ended November 30, 2022. The improvement in the ratio of cost of sales to sales for the six months ended November 30, 2023, over the prior period was primarily the result of an approximate 29.4% increase in pallet production and improvements in productivity and an approximate 36.2% decrease in the average cost of Greystone blended raw materials. The Company produces pallets manufactured using either customer materials or its Greystone blend of purchased recycled plastic.

 

Gross Profit

Gross profit for the six months ended November 30, 2023, was $7,187,227, or 21.8% of sales, compared to $3,685,520, or 11.9% of sales, for the six months ended November 30, 2022. The improved gross profits for the six months ended November 30, 2023, were the result of the Company’s changes to pricing of pallets manufactured with the Greystone blend, a drop in the cost of resin, and increased sales as discussed above.

 

Selling, General and Administrative Expenses

Selling, general and administrative expenses (SG&A) were $2,586,974, or 7.8% of sales, in the six months ended November 30, 2023 compared to $2,311,579, or 7.4% of sales, in the six months ended November 30, 2022 for an increase of $275,395. The increase is primarily due to enhanced efforts directed toward marketing Greystone’s pallets.

 

Other Income (Expenses)

During the six months ended November 30, 2022, Greystone recognized a gain on the deconsolidation of the variable interest entity GRE in the amount of $569,997.

 

 

Other income generally from the sale of scrap material in the six months ended November 30, 2023 was $3,153, and for the six months ended November 30, 2022 was $6,318.

 

Interest expense was $672,361 in the six months ended November 30, 2023 compared to $507,762 the six months ended November 30, 2022, representing an increase of $164,599. Greystone’s debt is based on the prime rate of interest which had a weighted average of 8.42% for the six months November 30, 2023, compared to 5.62% for the six months ended November 30, 2022.

 

Provision for Income Taxes

The provision for income taxes for the six months ended November 30, 2023 was $1,217,000 and for the six months ended November 30, 2022 was $256,000. The effective tax rate differs from federal statutory rates due principally to state income taxes, charges (income) which have no tax benefit (expense), changes in the valuation allowance, and the basis that net income from GRE is not taxable at the corporate level because GRE is a limited liability company of which Greystone has no equity ownership.

 

Based upon a review of its income tax filing positions, Greystone believes that its positions would be sustained upon an audit by the Internal Revenue Service and does not anticipate any adjustments that would result in a material change to its financial position. Therefore, no reserves for uncertain income tax positions have been recorded.

 

Net Income

Greystone recorded net income for the six months ended November 30, 2023 of $2,709,045 compared to the six months ended November 30, 2022 of $1,186,494 primarily for the reasons discussed above.

 

Net Income Attributable to Common Stockholders

The income attributable to common stockholders for the six months ending November 30, 2023 was $2,416,374, or $0.09 per share, compared to the six months ending November 30, 2022 of $908,128 or $0.03 per share, primarily for the reasons discussed above.

 

Three Months Ended November 30, 2023 Compared to Three Months Ended November 30, 2022

 

Sales

Sales for the three months ended November 30, 2023 were $15,597,036 compared to the three months ended November 30, 2022 of $12,101,674, for an increase of $3,495,362, or 28.9%. This increase in sales was principally the result of increased sales of approximately 29.5% in the quantity of pallets sold.

 

Greystone generally has a limited number of customers, generally 2 to 4, that accounted for approximately 85% and 77% of sales during the three months ended November 30, 2023 and 2022, respectively. Greystone is not able to predict the future needs of these major customers and will continue its efforts to increase sales through the addition of new customers developed through Greystone’s marketing efforts.

 

 

Cost of Sales

Cost of sales for the three months ended November 30, 2023 was $12,459,570, or 80% of sales, compared to the three months ended November 30, 2022 of $10,879,300, or 90% of sales. The improvement in cost of sales to sales for the three months ended November 30, 2023, over the prior period was primarily the result of an approximate 56.4% increase in pallet production allowing a larger base to allocate inflexible manufacturing costs and improvements in productivity. The Company produces pallets manufactured using either customer materials or its Greystone blend of purchased recycled plastic.

 

Selling, General and Administrative Expenses

Selling, general and administrative expenses (SG&A) were $1,374,024, or 8.8% of sales, for the three months ended November 30, 2023 compared to $1,205,988, or 10.0% of sales, for the three months ended November 30, 2022 for an increase of $168,036. SG&A costs during the current period compared to the prior period showed general consistency with past performance. The decrease in the percentage of SG&A to sales results from the increase of sales in the three months ended November 30, 2023 over three months ended November 30, 2022.

 

Other Income (Expenses)

Other income generally from the sale of scrap material for the three months ended November 30, 2023 was $1,554, and for the three months ended November 30, 2022 was $683.

 

Interest expense was $330,170 for the three months ended November 30, 2023 compared to $288,316 for the three months ended November 30, 2022, representing an increase of $164,599. Greystone’s debt is based on the prime rate of interest which had a weighted average of 8.42% for the six months November 30, 2023, compared to 5.62% for the six months ended November 30, 2022.

 

Provision for Income Taxes

The provision for (benefit from) income taxes for the three months ended November 30, 2023 was $470,000 and for the three months ended November 30, 2022 $(84,000). The effective tax rate differs from federal statutory rates due principally to state income taxes, charges or income which have no tax benefit or expense, changes in the valuation allowance, and the basis that the net income from GRE is not taxable at the corporate level because GRE is a limited liability company of which Greystone has no equity ownership.

 

Based upon a review of its income tax filing positions, Greystone believes that its positions would be sustained upon an audit by the Internal Revenue Service and does not anticipate any adjustments that would result in a material change to its financial position. Therefore, no reserves for uncertain income tax positions have been recorded.

 

Net Income (Loss)

Greystone recorded net income for the three months ended November 30, 2023 of $964,826 compared to a loss of $(187,247) for the three months ended November 30, 2022, primarily for the reasons discussed above.

 

 

Net Income (Loss) Attributable to Common Stockholders

The income attributable to common stockholders (net income less preferred dividends and GRE’s net income, as applicable) for the three months ended November 30, 2023 was $818,354, or $0.03 per share, compared to a loss attributable to common stockholders for the three months ended November 30, 2022 of $(306,596), or $(0.01) per share primarily for the reasons discussed above.

 

Liquidity and Capital Resources

 

A summary of cash flows for the six months ended November 30, 2023 is as follows:         

 

Cash provided by operating activities		$	7,730,472
Cash used in investing activities		$	(1,345,880	)

Greystone had a working capital of $6,998,197 as of November 30, 2023. To provide for the funding to meet Greystone's operating activities and contractual obligations as of November 30, 2023, Greystone will have to continue to produce positive operating results or explore various options including additional long-term debt and equity financing. However, there is no guarantee that Greystone will continue to create positive operating results or be able to raise sufficient capital to meet these obligations.

 

As of November 30, 2023, Greystone had no commitments for capital expenditures.

 

A substantial amount of Greystone’s debt financing has resulted primarily from bank notes which are guaranteed by certain officers and directors of Greystone. From time to time, loans have been provided by certain officers and directors of Greystone of which there are none outstanding as of November 30, 2023. Greystone continues to be dependent upon its officers and directors to secure, or possibly provide, additional financing and there is no assurance that its officers and directors will continue to do so, or that they will do so on terms that are acceptable to Greystone. As such, there is no assurance that funding will be available for Greystone to continue operations.

 

Greystone has 50,000 outstanding shares of cumulative 2003 Preferred Stock with a liquidation preference of $5,000,000 and a preferred dividend rate of the prime rate of interest plus 3.25%. Greystone does not anticipate that it will make cash dividend payments to any holders of its common stock unless and until the financial position of Greystone improves through increased revenues, another financing transaction or otherwise. Pursuant to the IBC Loan Agreement, as discussed in Note 6 to the consolidated financial statements, Greystone may pay dividends on its preferred stock in an amount not to exceed $500,000 per year.

 

 

Off-Balance Sheet Arrangements

 

Greystone does not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

 

Critical Accounting Policies and Estimates

 

Greystone believes that the following critical policies affect Greystone’s more significant judgments and estimates used in preparation of Greystone’s financial statements.

 

General

The preparation of unaudited consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“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.

 

Recognition of Revenues

Revenue is recognized at the point in time a good or service is transferred to a customer and the customer obtains control of that good or receives the service performed. Sales arrangements with customers are short-term in nature involving single performance obligations related to the delivery of goods and generally provide for transfer of control at the time of shipment. In limited circumstances, where acceptance of the goods is subject to approval by the customer, revenue is recognized upon approval by the customer unless, historically, there have been insignificant rejections of goods by the customer.

 

Accounts receivable

Trade receivables are carried at original invoice amount less an estimate made for doubtful accounts. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions. Trade receivables are written off against the allowance when deemed uncollectible. Recoveries of trade receivables previously written off are recorded when received. The Company generally does not charge interest on past due accounts. 

 

Inventory

Inventory consists of finished pallets and raw materials which are stated at the lower of average cost or net realizable value. Management applies overhead costs to inventory based on an analysis of the Company's expense categories. The specific costs are then applied to inventory based on production during the period. Management relies on estimates and assumptions regarding the specific costs to include in the production costs, as well as the period to use in determining inventory production.

 

Income Taxes

Greystone accounts for income taxes under the liability method, which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the consolidated financial statements and tax bases of assets and liabilities and tax loss carryforwards using enacted tax rates in effect for the year in which the differences are expected to reverse.

 

 

A deferred tax asset is recognized for tax-deductible temporary differences and operating losses using the applicable enacted tax rate. In assessing the realizability of deferred tax assets, management considers the likelihood of whether it is more likely than not the net deferred tax asset will be realized. Based on this evaluation, management will provide a valuation allowance if it is determined more likely than not the associated asset will not be recognized. Based on this, management has determined that Greystone will not be able to realize the full effect of the deferred tax assets and a valuation allowance of $793,337 and $1,044,361 has been recorded as of November 30, 2023 and May 31, 2023, respectively.

 

New Accounting Pronouncements

 

Management does not believe that any recently issued, but not yet effective, accounting standards could have a material effect on the accompanying unaudited consolidated financial statements. As new accounting pronouncements are issued, Greystone will adopt those that are applicable under the circumstances.

 

Recent accounting pronouncements issued by the Financial Accounting Standards Board, the American Institute of Certified Public Accountants and the SEC did not or are not believed by management to have a material effect on Greystone’s unaudited consolidated financial statements.

 

Item 3.

Quantitative and Qualitative Disclosures About Market Risk.

 

Not applicable.

 

Item 4.

Controls and Procedures.

 

As of the end of the period covered by this Quarterly Report on Form 10-Q, Greystone carried out an evaluation under the supervision of Greystone's Chief Executive Officer (CEO) and Chief Financial Officer (CFO) of the effectiveness of Greystone's disclosure controls and procedures pursuant to the Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (“Exchange Act”).  Based on an evaluation as of November 30, 2023, Greystone’s CEO and CFO concluded that Greystone’s disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act) were effective as of November 30, 2023.

 

During the six months ended November 30, 2023, there were no changes in Greystone's internal controls over financial reporting that have materially affected, or that are reasonably likely to materially affect, Greystone's internal control over financial reporting.

Notes to Financial Statements
Basis of Accounting [Text Block]	Note 1. Basis of Financial Statements   In the opinion of Greystone Logistics, Inc. (“Greystone” or the “Company”), the accompanying unaudited consolidated financial statements contain all adjustments and reclassifications, which are of a normal recurring nature, necessary to present fairly its financial position as of November 30, 2023, the results of its operations for the six months and three months ended November 30, 2023 and 2022 and its cash flows for the six months ended November 30, 2023 and 2022. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the fiscal year ended May 31, 2023 and the notes thereto included in the Form 10-K for such period. The results of operations for the six months and three months ended November 30, 2023 and 2022 are not necessarily indicative of the results to be expected for the full fiscal year.   The unaudited consolidated financial statements of Greystone include its wholly-owned subsidiaries, Greystone Manufacturing, L.L.C. (“GSM”) and Plastic Pallet Production, Inc. (“PPP”), and the variable interest entity, Greystone Real Estate, L.L.C. (“GRE”) for the period from June 1, 2022 through July 29, 2022. All material intercompany accounts and transactions have been eliminated in the unaudited consolidated financial statements.   GRE owns two buildings located in Bettendorf, IA, which are occupied by Greystone. GRE is wholly owned by Robert B. Rosene, Jr., a member of Greystone's Board of Directors. Effective July 29, 2022, GRE paid off its mortgage note payable, and in conjunction with the Company's refinancing described in Note 6, GRE was removed from the cross-collateralization agreement. Following these transactions Greystone was no longer determined to be the primary beneficiary of GRE. Accordingly, GRE was deconsolidated from the Greystone consolidated financial statements as of July 29, 2022, resulting in the recognition of a gain in the amount of $569,997. Subsequent to the deconsolidation, the Company entered into a new lease agreement with GRE and recorded right-of-use assets and liabilities for the new lease. See Note 7.

Notes to Financial Statements
Earnings Per Share [Text Block]	Note 2. Earnings Per Share   Basic earnings per share is based on the weighted-average effect of all common shares issued and outstanding and is calculated by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is calculated by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares used in the basic earnings per share calculation plus the number of common shares that would be issued assuming exercise or conversion of all potentially dilutive common shares outstanding.   Greystone excludes equity instruments from the calculation of diluted earnings per share if the effect of including such instruments is anti-dilutive. Instruments which have an anti-dilutive effect for the periods ended November 30 are as follows:         2023     2022   For the six months ended November 30:                 Preferred stock convertible into common stock     3,333,333       3,333,333   For the three months ended November 30:                 Preferred stock convertible into common stock     3,333,333       3,333,333   Warrants exercisable into common stock     -       500,000   Total     3,333,333       3,833,333     The following tables set forth the computation of basic and diluted earnings per share.   For the six months ended November 30, 2023 and 2022:       2023     2022   Basic earnings per share of common stock:                 Numerator -                 Net income attributable to common stockholders   $ 2,416,374     $ 908,128   Denominator -                 Weighted-average shares outstanding - basic     28,279,701       28,279,701   Income per share of common stock - basic   $ 0.09     $ 0.03                     Diluted earnings per share of common stock:                 Numerator -                 Net income attributable to common stockholders   $ 2,416,374     $ 908,128   Add: Preferred stock dividends for assumed conversion     -       -   Net income allocated to common stockholders   $ 2,416,374     $ 908,128   Denominator -                 Weighted-average shares outstanding – basic     28,279,701       28,279,701   Incremental shares from assumed conversion of warrants and preferred stock, as appropriate     494,861       493,506   Weighted average common stock outstanding – diluted     28,774,562       28,773,207   Income per share of common stock – diluted   $ 0.08     $ 0.03     For the three months ended November 30, 2023 and 2022:       2023     2022   Basic earnings per share of common stock:                 Numerator -                 Net income (loss) attributable to common stockholders   $ 818,354     $ (306,596 ) Denominator -                 Weighted-average shares outstanding - basic     28,279,701       28,279,701   Net income (loss) per share of common stock - basic   $ 0.03     $ (0.01 )                   Diluted earnings per share of common stock:                 Numerator -                 Net income (loss) attributable to common stockholders   $ 818,354     $ (306,596 ) Denominator -                 Weighted-average shares outstanding - basic     28,279,701       28,279,701   Incremental shares from assumed conversion of warrants and preferred stock, as appropriate     495,079       -   Weighted average common stock outstanding – diluted     28,774,780       28,279,701   Net income (loss) per share of common stock - diluted   $ 0.03     $ (0.01 )

These costs are shown on the consolidated balance sheet as a direct reduction to the related debt instrument. Amortization of these costs is included in interest expense. Greystone recorded amortization of debt issuance costs of $2,862 for each of the six months ended November 30, 2023 and 2022, respectively.   Restated and Amended Loan Agreement between Greystone and IBC On July 29, 2022, Greystone and GSM (each a “Borrower” and together, the “Borrowers”) entered into an Amended and Restated Loan Agreement (“IBC Restated Loan Agreement”) with International Bank of Commerce (“IBC”) that provided for the consolidation of certain term loans and a renewed revolver loan.   The IBC term loans require equal monthly payments of principal and interest in such amounts sufficient to amortize the principal balance of the loans over the remaining lives. The monthly payments of principal and interest on the IBC term loans may vary due to changes in the prime rate of interest. As of November 30, 2023, the aggregate payments for the IBC term loans are approximately $254,000 per month.   The IBC Restated Loan Agreement, dated July 29, 2022, as amended, provided for IBC to make certain term loans to Greystone to consolidate all existing term loans in the aggregate amount of approximately $2,700,000 and additional funding in the approximate amount of $13,200,000 for the purchase of equipment and renewal of the revolving loan with an increase of $2,000,000 to an aggregate principal amount of $6,000,000 (the “Revolving Loan”), subject to borrowing base limitations. As of November 30, 2023, Greystone’s available revolving loan borrowing capacity was approximately $4,000,000.   The IBC Restated Loan Agreement includes customary events of default, including events of default relating to non-payment of principal and other amounts owing under the IBC Restated Loan Agreement from time to time, inaccuracy of representations, violation of covenants, defaults under other agreements, bankruptcy and similar events, the death of a guarantor, certain material adverse changes relating to a Borrower or guarantor, certain judgments or awards against a Borrower, or government action affecting a Borrower’s or guarantor’s ability to perform under the IBC Restated Loan Agreement or the related loan documents. In addition, without prior written consent, Greystone shall not declare or pay any dividends, redemptions, distributions and withdrawals with respect to its equity interest other than distributions to holders of its preferred stock in the aggregate of $500,000 in any fiscal year. Among other things, a default under the IBC Restated Loan Agreement would permit IBC to cease lending funds under the IBC Restated Loan Agreement and require immediate repayment of any outstanding notes with interest and any unpaid accrued fees.     The IBC Restated Loan Agreement is secured by a lien on substantially all assets of the Borrowers. Warren F. Kruger, the Company’s President, CEO and Chairman of the Board and a significant stockholder of Greystone, and Robert B. Rosene, Jr., a member of the Company’s Board of Directors, have provided limited guaranties of the Borrowers’ obligations under the IBC Restated Loan Agreement. Mr. Kruger’s guarantee is limited to 32.4% of all debt obligations to IBC. Mr. Rosene’s limited guaranty is the lesser of (i) $3,500,000 less all amounts paid on the principal amount of the loans after the date of the agreement excluding payments on the revolver and (ii) the amount owed to IBC of the loans outstanding from time to time including accrued interest and fees.   Loan Agreement with First Interstate Bank, formerly Great Western Bank On August 23, 2021, Greystone entered into a loan agreement with First Interstate Bank (“FIB Loan Agreement”) to include prior commercial loans and subsequent loans. GSM is a named guarantor under the FIB Loan Agreement.   The FIB Loan Agreement includes customary representations and warranties and affirmative and negative covenants which include (i) requiring the Borrowers to maintain a debt service coverage ratio of 1:25 to 1:00 as of the end of each fiscal year end and debt to tangible net worth ratio of 4:00 to 1:00 as of the end of each fiscal year end with a decrease of 0.50 in the ratio each year thereafter until reaching a minimum ratio of 3:00 to 1:00. In addition, the FIB Loan Agreement provides that Greystone shall not, without prior consent of the bank, incur or assume additional indebtedness or capital leases.   The FIB Loan Agreement is secured by a mortgage on one of Greystone’s warehouses.   Maturities Maturities of Greystone’s long-term debt for the five years subsequent to November 30, 2023, are $2,321,333, $2,269,023, $2,257,551, $7,281,401 and $540,580.

Concentrations, Risks and Uncertainties   Greystone derived approximately 83% and 73% of its total sales from three customers during the six months ended November 30, 2023 and 2022, respectively. The loss of a material amount of business from one or more of these customers could have a material adverse effect on Greystone.   Greystone purchases damaged pallets from its customers at a price based on the value of the raw material content in the pallet. A majority of these purchases, totaling $470,648 for the six months ended November 30, 2023 and $313,050 for the six months ended November 30, 2022, were from one of its major customers.     Greystone is subject to litigation, claims and other commitments and contingencies arising in the ordinary course of business.
