(Unaudited)

Note 1. Basis of Financial Statements

In the opinion of Greystone Logistics, Inc. (“Greystone”), 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 February 28, 2018, the results of its operations for the nine-month and three-month periods ended February 28, 2018 and 2017, and its cash flows for the nine-month periods ended February 28, 2018 and 2017. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the fiscal year ended May 31, 2017 and the notes thereto included in Greystone’s Form 10-K for such period. The results of operations for the nine-month and three-month periods ended February 28, 2018 and 2017 are not necessarily indicative of the results to be expected for the full fiscal year.

The 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”). GRE owns two buildings located in Bettendorf, Iowa which are leased to GSM.

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) available to common stockholders by the weighted-average shares outstanding during the period. Diluted earnings per share is calculated by dividing net income (loss) available 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, as follows:

	2018		2017
Nine-month periods ended February 28:
Preferred stock convertible into common stock		3,333,333		3,333,333

Loan Agreement between Greystone and IBC

The Loan Agreement (“IBC Loan Agreement”), dated January 31, 2014, among Greystone and GSM (the “Borrowers”) and International Bank of Commerce (“IBC”), as amended, provides for certain term loans and a revolver loan.

Effective January 10, 2018, the Borrowers and IBC entered into the Fifth Amendment to the IBC Loan Agreement providing (i) a conversion of the existing revolver loan with an outstanding balance of $2,500,000 into Term Loan D with a maturity date of January 10, 2022, (ii) an advancing Term Loan E of $1,000,000 with a maturity date of January 10, 2022 for the procurement of production equipment, and (iii) an amended and modified revolving loan of $3,000,000 with a maturity date of January 31, 2020. The three notes bear interest at the greater of the prime rate of interest plus 0.5%, or 4.75%.

Effective August 4, 2017, the Borrowers and IBC entered into the Fourth Amendment to the IBC Loan Agreement providing for Term Loan C in the amount of $1,795,000 for the purchase of certain production equipment. Term Loan C bears interest at the greater of prime plus 0.5%, or 4.00% and matures August 4, 2020.

The IBC term loans make equal monthly payments of principal and interest in such amounts sufficient to amortize the principal balance of (i) Term Loan A over a seven-year period beginning January 31, 2016 (currently $74,455 per month), (ii) Term Loan C over a seven-year period beginning August 31, 2017 (currently $25,205 per month) and (iii) Term Loan D over a four-year period beginning August 4, 2020 (currently $57,469 per month). Term Loan E requires monthly interest payments until January 10, 2019, after which monthly payments of principal and interest are required in an amount sufficient to amortize the loan over a four-year period. The monthly payments of principal and interest on the IBC term loans may vary as a result of changes in the prime rate of interest.

The IBC Loan Agreement, as amended, provides a revolving loan in an aggregate principal amount of up to $3,000,000 (the “Revolving Loan”). The exact amount which can be borrowed under the Revolving Loan from time to time is dependent upon the amount of the borrowing base, but can in no event exceed $3,000,000.The Revolving Loan bears interest at greater of the prime rate of interest plus 0.5%, or 4.75% and matures January 31, 2020. The Borrowers are required to pay all interest accrued on the outstanding principal balance of the Revolving Loan on a monthly basis. Any principal on the Revolving Loan that is prepaid by the Borrowers does not reduce the original amount available to the Borrowers.

The IBC 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 and a funded debt to EBIDA ratio not exceeding 3:00 to 1:00 measured quarterly, (ii) subject to certain exceptions, limiting the Borrowers’ combined capital expenditures on fixed assets to $1,500,000 per year, (iii) prohibiting Greystone, without IBC’s prior written consent, from declaring or paying any dividends, redemptions of stock or membership interests, distributions and withdrawals (as applicable) in respect of its capital stock or any other equity interest, other than additional payments to holders of its preferred stock in an amount not to exceed $500,000 in any fiscal year, (iv) subject to certain exceptions, prohibiting the incurrence of additional indebtedness by the Borrowers, and (v) requiring the Borrowers to prevent (A) any change in capital ownership such that there is a material change in the direct or indirect ownership of (1) Greystone’s outstanding preferred stock, and (2) any equity interest in GSM, or (B) Warren Kruger from ceasing to be actively involved in the management of Greystone as President and/or Chief Executive Officer. The foregoing list of covenants is not exhaustive and there are several other covenants contained in the IBC Loan Agreement.

As of February 28, 2018, management has concluded that Greystone was in compliance with the covenants of the IBC Loan Agreement.

The IBC Loan Agreement includes customary events of default, including events of default relating to non-payment of principal and other amounts owing under the IBC 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 Loan Agreement or the related loan documents. Among other things, a default under the IBC Loan Agreement would permit IBC to cease lending funds under the IBC Loan Agreement, and require immediate repayment of any outstanding notes with interest and any unpaid accrued fees.

The IBC Loan Agreement is secured by a lien on substantially all of the assets of the Borrowers. In addition, the IBC Loan Agreement is secured by a mortgage granted by GRE on the real property owned by GRE in Bettendorf, Iowa (the “Mortgage”). GRE is owned by Warren F. Kruger, Greystone’s President and CEO, and Robert B. Rosene, Jr., a director of Greystone. Messrs. Kruger and Rosene have provided a combined limited guaranty of the Borrowers’ obligations under the IBC Loan Agreement, with such guaranty being limited to a combined amount of $6,500,000 (the “Guaranty”). The Mortgage and the Guaranty also secure or guaranty, as applicable, the obligations of GRE under the Loan Agreement between GRE and IBC dated January 31, 2014 as discussed in the following paragraph.

Loan Agreement between GRE and IBC

On January 31, 2014, GRE and IBC entered into a Loan Agreement which provided for a mortgage note to GRE of $3,412,500. The note provides for a 4.5% interest rate and a maturity of January 31, 2019 and is secured by a mortgage on the two buildings in Bettendorf, Iowa which are leased to Greystone.

Note Payable between Greystone and Robert B. Rosene, Jr.

Effective December 15, 2005, Greystone entered into an agreement with Robert B. Rosene, Jr., a member of Greystone’s board of directors, to convert $2,066,000 of advances into an unsecured note payable at 7.5% interest. Effective June 1, 2016, the note was restated (the “Restated Note”) to combine the outstanding principal, $2,066,000, and accrued interest, $2,475,690, into an unsecured note payable of $4,541,690 with an extended maturity date of January 15, 2020. The Restated Note provides that accrued interest is payable monthly and allows Greystone to use commercially reasonable efforts to pay such amounts as allowed by the IBC Loan Agreement against the interest accrued prior to the restatement.

Note Payable between Greystone and Yorktown Management Financial Services, LLC (“Yorktown”)

On February 29, 2016, Greystone entered into an unsecured note payable to Yorktown in the amount of $688,296 in connection with the acquisition of equipment from Yorktown. The note payable bears interest at the rate of 5% and is payable over three years with monthly principal and interest payments of $20,629.

Maturities

Maturities of Greystone’s long-term debt for the five years subsequent to February 28, 2018 are $8,240,541, $5,910,483, $3,078,725, $381,709 and $-0-.

The current maturities of long-term debt include two notes with IBC with a January 31, 2019 maturity – IBC Term Loan A with a February 28, 2018 balance of $4,116,415 and a term loan payable by GRE to IBC with a February 28, 2018 balance of $2,700,205. Greystone and IBC are currently reviewing these notes for an extension or renewal.

Note 7. Capital Leases

Capital leases as of February 28, 2018 and May 31, 2017:

	February 28, 2018			May 31, 2017
Non-cancellable capital leases with private company, interest rates of 7.4% and 5.0%, maturing February 24, 2023 and August 7, 2019	$	4,229,234		$	3,794,063
Less: Current portion		(2,432,198	)		(2,261,560	)
Non-cancellable capital leases, net of current portion	$	1,797,036		$	1,532,503

In February, 2018, Greystone entered into a five-year lease agreement, interest rate of 7.4% and maturity date of February 24, 2023, (“Agreement A”) with an unrelated private company to provide for certain production equipment with a cost of approximately $2.0 million. In August, 2016, Greystone entered into a three-year lease agreement, interest rate of 5.0% and maturity date of August 7, 2019, (“Agreement B”) with the same unrelated private company to provide for certain production equipment with a total cost of approximately $5.4 million. The lease agreements include a bargain purchase option to acquire the production equipment at the end of the lease terms. Lease payments are made on a per invoice basis at rates of (i) $3.32 per pallet produced on the leased equipment and sold to the private company, estimated payments of $40,000 per month, for Agreement A and (ii) $6.25 per pallet produced on the equipment and sold to the private company, approximately $200,000 per month, for Amendment B. Both Agreements A & B provide for minimum monthly lease rental payments based upon the total pallets sold in excess of a specified amount not to exceed the monthly productive capacity of the leased machines.

The production equipment under the non-cancelable capital leases has a gross carrying amount of $7,322,364 at February 28, 2018. Amortization of the carrying amount of approximately $402,000 and $246,000 was included in depreciation expense for the nine months ended February 28, 2018 and 2017, respectively.

Future minimum lease payments under non-cancelable capital leases as of February 28, 2018, are approximately:

Twelve months ended February 28, 2019	$	2,844,000
Twelve months ended February 28, 2020		573,700
Twelve months ended February 28, 2021		573,700
Twelve months ended February 28, 2022		573,700
Twelve months ended February 28, 2023		240,500
Total lease payments		4,805,600
Imputed interest		576,366
Present value of minimum lease payments	$	4,229,234

13

Note 8. Deferred Revenue

In February, 2018, a new customer entered into a contract with Greystone to purchase plastics pallets with shipments occurring from May, 2018 through about August, 2018. The customer prepaid $4,595,034 to provide funding to Greystone for procuring raw materials to produce the pallets. Revenue will be recognized by Greystone as pallets are shipped to the customer.

Note 9. 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 in the balance sheet approximate fair value.

Note 10. Concentrations, Risks and Uncertainties

Greystone derived approximately 76% and 67% of its total sales from two customers in fiscal years 2018 and 2017, respectively. The loss of a material amount of business from one or both 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 $1,200,335 and $1,202,381 in fiscal years 2018 and 2017, respectively, is from one of its major customers.

Robert B. Rosene, Jr., a Greystone director, has provided financing and guarantees on Greystone’s bank debt. As of February 28, 2018, Greystone is indebted to Mr. Rosene in the amount of $4,469,355 for a note payable due January 15, 2020. There is no assurance that Mr. Rosene will renew the note as of the maturity date.

Note 11. Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers” (“ASU 14-09”) which creates a comprehensive set of guidelines for the recognition of revenue under the principle: “Recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” The requirements of ASU 14-09 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and will require either retrospective application to each prior period presented or retrospective application with the cumulative effect of initially applying the standard recognized at the date of adoption. Management believes that the impact of this ASU will not have a material effect on our financial position and results of operations.

14

In February 2016, the FASB issued Accounting Standards 2016-02, Leases (Topic 842), which is intended to improve financial reporting about leasing transactions. The ASU will require organizations (“lessees”) that lease assets with lease terms of more than twelve months to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. In addition, the ASU will require disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. The effective date of this ASU is for fiscal years beginning after December 31, 2018 and interim periods within that year. Greystone is currently reviewing the ASU to assess the potential impact on the consolidated financial statements.

Note 12. Income Taxes

On December 22, 2017, the President signed into legislation The Tax Cuts and Jobs Act (the Act). The Act changes existing U.S. tax law and includes numerous provisions that will affect Greystone’s business, including income tax accounting, disclosure and tax compliance. As a result of the changes in tax rates as provided in the Act and reassessing deferred income taxes using state income tax rates, Greystone revalued all deferred tax assets and liabilities, and as a result, the deferred taxes at February 28, 2018 decreased $474,100 and the provision for income taxes for the three months ended February 28, 2018 increased by a like amount.

Note 13. Commitments

At February 28, 2018, Greystone had commitments totaling $702,508 toward the purchase of production equipment. In March, 2018, Greystone issued a purchase order for certain production equipment at a cost of approximately $2.3 million.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

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 consolidates its variable interest entity, Greystone Real Estate, L.L.C. (“GRE”). All material intercompany accounts and transactions have been eliminated.

References to fiscal year 2018 refer to the nine and three month periods ended February 28, 2018. References to fiscal year 2017 refer to the nine and three month periods ended February 28, 2017.

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.

15

Personnel

Greystone had approximately 197 and 158 full-time employees as of February 28, 2018 and 2017, respectively.

Nine-Month Period Ended February 28, 2018 Compared to Nine-Month Period Ended February 28, 2017

Sales

Sales for fiscal year 2018 were $32,073,828 compared to $25,759,823 in fiscal year 2017 for an increase of $6,314,005. The increase in pallet sales in fiscal year 2018 over 2017 was primarily due to sales growth to a pallet leasing company, one of Greystone’s major customers. To meet customer demand, Greystone will install a leased injection mold machine with estimated delivery in May, 2018. In March, 2018, Greystone placed an order to purchase another injection molding machine for estimated delivery in November 2018.

Greystone has two major customers which accounted for approximately 76% and 67% of sales in fiscal years 2018 and 2017, respectively. Pallet sales to Greystone’s major customers are generally based on the customers’ needs which may vary by period. 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 in fiscal year 2018 was $27,325,588, or 85% of sales, compared to $21,103,691, or 82% of sales, in fiscal year 2017. Greystone achieved a 25% increase in sales volume from fiscal year 2017 to 2018. The impact of this significant increase in sales volume had a direct effect on production costs resulting in the increase in the ratio of cost of sales to sales from fiscal year 2017 to 2018. Substantial increases in the number of employees, training and operating costs, recycling costs and the addition of five new injection molding machines plus associated supporting equipment have resulted in the increase in the ratio of cost of sales to sales during fiscal year 2018. Greystone continues to monitor pricing, operating procedures and cost of operations toward reducing the production costs of pallets thereby improving gross margins from sales.

General, Selling and Administrative Expenses

General, selling and administrative expenses were $2,177,164 in fiscal year 2018 compared to $2,133,228 in fiscal year 2017 for an increase of $43,936, or approximately 2%. The difference between fiscal year 2018 and fiscal year 2017 is primarily attributable to timing of expenses for the respective periods.

16

Other Income (Expenses)

Other income was $5,867 and $-0- in fiscal years 2018 and 2017, respectively. The source of other income is the sale of scrap material.

Interest expense was $997,944 and $832,887 in fiscal years 2018 and 2017 for an increase of $165,057. The increase in interest expense in fiscal year 2018 over fiscal year 2017 is principally due to an increase in the weighted average of the prime rate of interest (4.31% in fiscal year 2018 compared to 3.57% in fiscal year 2017) and an approximately $50,000 increase in amortization expense associated with debt service costs.

Provision for Income Taxes

The provision for income taxes was $899,100 and $556,700 in fiscal years 2018 and 2017, respectively. The provision for income taxes includes an added adjustment of $474,100 in fiscal year 2018 as discussed in Note 11, Income Taxes, in the notes to the consolidated financial statements. The provision for income taxes does not include the income from the variable interest entity as the entity is not included in the income tax returns of Greystone and the taxable income of the entity is passed-through to the respective owners.

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 of $679,899 in fiscal year 2018 compared to $1,133,317 in fiscal year 2017 primarily for the reasons discussed above.

Net Income Attributable to Common Stockholders

Net income attributable to common stockholders for fiscal year 2018 was $210,817, or $0.01 per share, compared to $697,337, or $0.02 per share, in fiscal year 2017 primarily for the reasons discussed above.

17

Three-Month Period Ended February 28, 2018 Compared to Three-Month Period Ended February 28, 2017

Sales

Sales for fiscal year 2018 were $12,064,651 compared to $8,693,851 in fiscal year 2017 for an increase of $3,370,800. The increase in pallet sales in fiscal year 2018 over 2017 was primarily due to sales growth to a pallet leasing company, one of Greystone’s major customers.

Greystone has two major customers who accounted for approximately 80% and 67% of sales in fiscal years 2018 and 2017, respectively. Pallet sales to Greystone’s major customers are generally based on the customers’ need which may vary by period. 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 in fiscal year 2018 was $10,349,347, or 86% of sales, compared to $6,234,807, or 72% of sales, in fiscal year 2017. Greystone achieved a 39% increase in sales volume from fiscal year 2017 to 2018. The impact of this significant increase in sales volume had a direct effect on production costs resulting in the increase in the ratio of cost of sales to sales from fiscal year 2017 to 2018. Substantial increases in the number of employees, training and operating costs, recycling costs and the addition of five new injection molding machines plus associated supporting equipment have resulted in the increase in the ratio of cost of sales to sales during fiscal year 2018. Greystone continues to monitor pricing, operating procedures and cost of operations toward reducing the production costs of pallets thereby improving gross margins from sales.

General, Selling and Administrative Expenses

General, selling and administrative expenses were $724,748 in fiscal year 2018 compared to $745,924 in fiscal year 2017 for a decrease of $21,176 or 3%. The difference between fiscal year 2018 and fiscal year 2017 is primarily attributable to timing of expenses for the respective periods.

Other Income (Expenses)

Other income (loss) was $(6,202) and $-0- in fiscal years 2018 and 2017, respectively. The loss is attributable to a sale of equipment.

Interest expense was $339,208 in fiscal year 2018 compared to $290,087 in fiscal year 2017 for an increase of $49,121. The increase is principally attributable to increases in the weighted average of the prime rate of interest between fiscal year 2018 and 2017 (4.46% in fiscal year 2018 compared to 3.96% in fiscal year 2017).

18

Provision for Income Taxes

The provision for income taxes was $639,600 and $502,150 in fiscal years 2018 and 2017, respectively. The provision for income taxes includes an added adjustment of $474,100 in fiscal year 2018 as discussed in Note 11, Income Taxes, in the notes to the consolidated financial statements. The provision for income taxes does not include the income from the variable interest entity as the entity is not included in the income tax returns of Greystone and the taxable income from this entity is passed-through to the respective owners.

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 of $5,546 in fiscal year 2018 compared to net income of $920,883 in fiscal year 2017 primarily for the reasons discussed above.

Net Income (Loss) Attributable to Common Stockholders

The net loss attributable to common stockholders for fiscal year 2018 was $(152,554), or $(0.01) per share, compared to net income of $773,667, or $0.03 per share, in fiscal year 2017 primarily for the reasons discussed above.

Liquidity and Capital Resources

A summary of cash flows for the nine-month period ended February 28, 2018 is as follows:

Cash provided by operating activities	$	5,999,327
Cash used in investing activities	$	(3,765,337	)
Cash used in financing activities	$	(2,478,975	)

The contractual obligations of Greystone for long-term debt and capital lease obligations are as follows:

	Total		Less than 1 year		1-3 years		4-5 years		More than 5 years
Long-term debt and capital leases	$	21,840,692	$	10,672,739	$	9,979,980	$	1,187,973	$	-0-

19

Greystone had a working capital deficit of $(9,886,547) at February 28, 2018. To provide for the funding to meet Greystone’s operating activities and contractual obligations as of February 28, 2018, 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.

The current maturities of long-term debt include two notes with IBC with a January 31, 2019 maturity – IBC Term Loan A with a February 28, 2018 balance of $4,116,415 and a term loan payable by GRE to IBC with a February 28, 2018 balance of $2,700,205. Greystone and IBC are currently reviewing these notes for an extension or renewal. Management believes that Greystone and IBC will enter into an agreement for the extensions or renewals.

Effective January 10, 2018 and as discussed further in Note 12 to the consolidated financial statements, Greystone and IBC entered into the Fifth Amendment to the IBC Loan Agreement dated January 31, 2014 which provided for (1) converting the existing revolving loan with a balance of $2,500,000 at February 28, 2018 into a four-year term loan, (2) new funding in the amount of $1,000,000 for the purchase of production equipment with monthly interest payments only for one year then monthly principal and interest sufficient to amortize the loan over four years and (3) a new revolving loan for $3,000,000 with a maturity date of January 31, 2020. Additionally, during fiscal year 2018, production equipment valued at approximately $2.0 million was acquired through a leasing arrangement.

Substantially all of the financing that Greystone has received through the last few fiscal years resulted from loans provided by certain officers and directors of Greystone and bank notes which are guaranteed by certain officers and directors of Greystone. Greystone continues to be dependent upon its officers and directors to provide and/or secure additional financing and there is no assurance that its officers and directors will continue to do so. 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.

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. These forward-looking statements are made in reliance on the safe harbor protections provided under the Private Securities Litigation Reform Act of 1995. 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 Form 10-K for the fiscal year ended May 31, 2017, which was filed on August 25, 2017. Actual results may vary materially from the forward-looking statements. Greystone undertakes no duty to update any of the forward-looking statements contained in this Quarterly Report on Form 10-Q.

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 and Chief Financial Officer of the effectiveness of the design and operation of Greystone’s disclosure controls and procedures pursuant to the Securities Exchange Act Rules 13a-15(e) and 15d-15(e). Based on an evaluation as of May 31, 2017, Warren F. Kruger, Greystone’s Chief Executive Officer, and William W. Rahhal, Greystone’s Chief Financial Officer, identified one material weakness in Greystone’s internal control over financial reporting. As of the end of the period covered by this Quarterly Report on Form 10-Q, such material weaknesses had not been rectified. As a result of the continuation of this material weakness, Greystone’s CEO and Chief Financial Officer concluded that Greystone’s disclosure controls and procedures were not effective at February 28, 2018.

During the nine-month period ended February 28, 2018, 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.

Earnings Per Share [Abstract]

Earnings Per Share

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) available to common stockholders by the weighted-average shares outstanding during the period. Diluted earnings per share is calculated by dividing net income (loss) available 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, as follows:

	2018		2017
Nine-month periods ended February 28:
Preferred stock convertible into common stock		3,333,333		3,333,333
Total		3,333,333		3,333,333

Preferred stock convertible into common stock		3,333,333		3,333,333
Total		4,033,333		3,333,333

The following tables set forth the computation of basic and diluted earnings per share for the following periods:

Loan Agreement between Greystone and IBC

The Loan Agreement (“IBC Loan Agreement”), dated January 31, 2014, among Greystone and GSM (the “Borrowers”) and International Bank of Commerce (“IBC”), as amended, provides for certain term loans and a revolver loan.

Effective January 10, 2018, the Borrowers and IBC entered into the Fifth Amendment to the IBC Loan Agreement providing (i) a conversion of the existing revolver loan with an outstanding balance of $2,500,000 into Term Loan D with a maturity date of January 10, 2022, (ii) an advancing Term Loan E of $1,000,000 with a maturity date of January 10, 2022 for the procurement of production equipment, and (iii) an amended and modified revolving loan of $3,000,000 with a maturity date of January 31, 2020. The three notes bear interest at the greater of the prime rate of interest plus 0.5%, or 4.75%.

Effective August 4, 2017, the Borrowers and IBC entered into the Fourth Amendment to the IBC Loan Agreement providing for Term Loan C in the amount of $1,795,000 for the purchase of certain production equipment. Term Loan C bears interest at the greater of prime plus 0.5%, or 4.00% and matures August 4, 2020.

The IBC term loans make equal monthly payments of principal and interest in such amounts sufficient to amortize the principal balance of (i) Term Loan A over a seven-year period beginning January 31, 2016 (currently $74,455 per month), (ii) Term Loan C over a seven-year period beginning August 31, 2017 (currently $25,205 per month) and (iii) Term Loan D over a four-year period beginning August 4, 2020 (currently $57,469 per month). Term Loan E requires monthly interest payments until January 10, 2019, after which monthly payments of principal and interest are required in an amount sufficient to amortize the loan over a four-year period. The monthly payments of principal and interest on the IBC term loans may vary as a result of changes in the prime rate of interest.

The IBC Loan Agreement, as amended, provides a revolving loan in an aggregate principal amount of up to $3,000,000 (the “Revolving Loan”). The exact amount which can be borrowed under the Revolving Loan from time to time is dependent upon the amount of the borrowing base, but can in no event exceed $3,000,000.The Revolving Loan bears interest at greater of the prime rate of interest plus 0.5%, or 4.75% and matures January 31, 2020. The Borrowers are required to pay all interest accrued on the outstanding principal balance of the Revolving Loan on a monthly basis. Any principal on the Revolving Loan that is prepaid by the Borrowers does not reduce the original amount available to the Borrowers.

The IBC 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 and a funded debt to EBIDA ratio not exceeding 3:00 to 1:00 measured quarterly, (ii) subject to certain exceptions, limiting the Borrowers’ combined capital expenditures on fixed assets to $1,500,000 per year, (iii) prohibiting Greystone, without IBC’s prior written consent, from declaring or paying any dividends, redemptions of stock or membership interests, distributions and withdrawals (as applicable) in respect of its capital stock or any other equity interest, other than additional payments to holders of its preferred stock in an amount not to exceed $500,000 in any fiscal year, (iv) subject to certain exceptions, prohibiting the incurrence of additional indebtedness by the Borrowers, and (v) requiring the Borrowers to prevent (A) any change in capital ownership such that there is a material change in the direct or indirect ownership of (1) Greystone’s outstanding preferred stock, and (2) any equity interest in GSM, or (B) Warren Kruger from ceasing to be actively involved in the management of Greystone as President and/or Chief Executive Officer. The foregoing list of covenants is not exhaustive and there are several other covenants contained in the IBC Loan Agreement.

As of February 28, 2018, management has concluded that Greystone was in compliance with the covenants of the IBC Loan Agreement.

The IBC Loan Agreement includes customary events of default, including events of default relating to non-payment of principal and other amounts owing under the IBC 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 Loan Agreement or the related loan documents. Among other things, a default under the IBC Loan Agreement would permit IBC to cease lending funds under the IBC Loan Agreement, and require immediate repayment of any outstanding notes with interest and any unpaid accrued fees.

The IBC Loan Agreement is secured by a lien on substantially all of the assets of the Borrowers. In addition, the IBC Loan Agreement is secured by a mortgage granted by GRE on the real property owned by GRE in Bettendorf, Iowa (the “Mortgage”). GRE is owned by Warren F. Kruger, Greystone’s President and CEO, and Robert B. Rosene, Jr., a director of Greystone. Messrs. Kruger and Rosene have provided a combined limited guaranty of the Borrowers’ obligations under the IBC Loan Agreement, with such guaranty being limited to a combined amount of $6,500,000 (the “Guaranty”). The Mortgage and the Guaranty also secure or guaranty, as applicable, the obligations of GRE under the Loan Agreement between GRE and IBC dated January 31, 2014 as discussed in the following paragraph.

Loan Agreement between GRE and IBC

On January 31, 2014, GRE and IBC entered into a Loan Agreement which provided for a mortgage note to GRE of $3,412,500. The note provides for a 4.5% interest rate and a maturity of January 31, 2019 and is secured by a mortgage on the two buildings in Bettendorf, Iowa which are leased to Greystone.

Note Payable between Greystone and Robert B. Rosene, Jr.

Effective December 15, 2005, Greystone entered into an agreement with Robert B. Rosene, Jr., a member of Greystone’s board of directors, to convert $2,066,000 of advances into an unsecured note payable at 7.5% interest. Effective June 1, 2016, the note was restated (the “Restated Note”) to combine the outstanding principal, $2,066,000, and accrued interest, $2,475,690, into an unsecured note payable of $4,541,690 with an extended maturity date of January 15, 2020. The Restated Note provides that accrued interest is payable monthly and allows Greystone to use commercially reasonable efforts to pay such amounts as allowed by the IBC Loan Agreement against the interest accrued prior to the restatement.

Note Payable between Greystone and Yorktown Management Financial Services, LLC (“Yorktown”)

On February 29, 2016, Greystone entered into an unsecured note payable to Yorktown in the amount of $688,296 in connection with the acquisition of equipment from Yorktown. The note payable bears interest at the rate of 5% and is payable over three years with monthly principal and interest payments of $20,629.

Maturities

Maturities of Greystone’s long-term debt for the five years subsequent to February 28, 2018 are $8,240,541, $5,910,483, $3,078,725, $381,709 and $-0-.

The current maturities of long-term debt include two notes with IBC with a January 31, 2019 maturity – IBC Term Loan A with a February 28, 2018 balance of $4,116,415 and a term loan payable by GRE to IBC with a February 28, 2018 balance of $ 2,700,205. Greystone and IBC are currently reviewing these notes for an extension or renewal.

Note 10. Concentrations, Risks and Uncertainties

Greystone derived approximately 76% and 67% of its total sales from two customers in fiscal years 2018 and 2017, respectively. The loss of a material amount of business from one or both 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 $1,200,335 and $1,202,381 in fiscal years 2018 and 2017, respectively, is from one of its major customers.

Robert B. Rosene, Jr., a Greystone director, has provided financing and guarantees on Greystone’s bank debt. As of February 28, 2018, Greystone is indebted to Mr. Rosene in the amount of $4,469,355 for a note payable due January 15, 2020. There is no assurance that Mr. Rosene will renew the note as of the maturity date.

Recent Accounting Pronouncements

Note 11. Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers” (“ASU 14-09”) which creates a comprehensive set of guidelines for the recognition of revenue under the principle: “Recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” The requirements of ASU 14-09 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and will require either retrospective application to each prior period presented or retrospective application with the cumulative effect of initially applying the standard recognized at the date of adoption. Management believes that the impact of this ASU will not have a material effect on our financial position and results of operations.

In February 2016, the FASB issued Accounting Standards 2016-02, Leases (Topic 842), which is intended to improve financial reporting about leasing transactions. The ASU will require organizations (“lessees”) that lease assets with lease terms of more than twelve months to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. In addition, the ASU will require disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. The effective date of this ASU is for fiscal years beginning after December 31, 2018 and interim periods within that year. Greystone is currently reviewing the ASU to assess the potential impact on the consolidated financial statements.
