Mark Wong, president and chief executive officer of S&W Seed Company, commented, "Over the past year, the management team and S&W's board have been aligned on a comprehensive strategic plan to become a more diversified middle market agricultural company. Our focus is to evolve beyond our dependence on our alfalfa seed operations and certain geographical markets which carry higher political, regulatory, and economic risks, and at the same time develop and acquire higher-value trait technologies."

"In particular, we have made significant advancements with our Calyxt partnership where we recently announced the successful transfer of our proprietary alfalfa seed and plants from the research and development facility at Calyxt to S&W for field evaluation and testing. This marked a significant milestone in the collaboration between the two companies. We have expanded our sales and marketing capabilities with the appointment of key industry veterans that create the bridge that connects our R&D to our sales teams and ultimately our customers. At the same time, we have created a joint venture with AGT Foods Africa (Pty) Ltd, and further integrated our acquired NexSteppe sorghum germplasm, that will increase our sorghum presence in key regions. This focus on commercialization efforts matches a simultaneous focus on research and development and advancement of our stevia efforts where we expanded our existing agreement with an international consumer products company to perform breeding and targeting of novel stevia traits. Overall, we are pleased with the progress made to achieve our goals."

"During fiscal year 2018, Saudi Arabian water regulations continued to impact revenue and profitability. However, alfalfa seed revenues in other regions have remained relatively flat over the past couple of years, despite difficult market environments. We have instituted a series of initiatives within our alfalfa operations to drive continued focus in key geographies, while at the same time investing in trait technologies that we believe will help grow market share in the future."

Mr. Wong concluded, "Our mantra during the year has been `Evolving Beyond.' I am pleased with our progress over the last year to better position us for success by advancing key alfalfa trait development, expanding our sorghum operations, better alignment of our sales and marketing strategies, progressing our stevia program, and increasing the value we obtain for each pound of seed sold. I look forward to continued progress in fiscal 2019."

For the fiscal year ended June 30, 2018, S&W reported revenue of $64.1 million, compared to revenue of $75.4 million in fiscal 2017. The decrease was largely attributable to decreased shipments to Saudi Arabia as a result of water use regulations in the country. For fiscal 2018, revenue from Saudi Arabian destinations was $1.5 million compared to $12.1 million in fiscal 2017, and $26.0 million in fiscal 2016. Revenue in the United States, S&W's largest market, was $41.7 million in fiscal 2018 compared to $41.5 million in fiscal 2017.

Gross margins during fiscal 2018 improved 160 basis points to 23.0% compared to gross margins of 21.4% in fiscal 2017. This improvement in gross margins was primarily due to product sales mix during the year where the Company had a higher concentration of sales, as a percentage of total revenue, to Pioneer; coupled with reductions of production costs of proprietary seed.

Total operating expenses in fiscal 2018 were $17.7 million compared to $18.5 million in fiscal 2017. Adjusted operating expenses (see Table A-2) during fiscal 2018 were $17.7 million, compared to $17.3 million in fiscal 2017. On an adjusted basis, SG&A decreased by $520,000, while R&D increased by $856,000 over the prior year. S&W continues to focus on operating efficiencies while maintaining an investment in developing next generation products that are intended to drive growth in revenues and gross profit margins. Included in fiscal 2018 operating expenses was a charge of $66,000 related to transactions expenses, whereas included in fiscal 2017 operating expenses was a charge of $837,000 related to employee separation costs, a $319,000 impairment charge related to the carrying value of certain stand establishment assets and a $60,000 reserve for uncollectable sub-lease income.

GAAP net loss for fiscal 2018 was $(4.7) million, or $(0.21) per basic and diluted share, compared to GAAP net loss of $(11.8) million, or $(0.67) per basic and diluted share, in fiscal 2017. In fiscal 2017, the Company recorded a valuation allowance of $9.6 million against its deferred tax assets which resulted in GAAP income tax expense of $8.2 million for the fourth quarter of fiscal 2017.

Adjusted non-GAAP net loss (see Table A-2) for fiscal 2018, excluding various items (transaction costs, change in derivative warrant liabilities, and interest expense - amortization of debt discount), was $(4.9) million, or $(0.22) per basic and diluted share. Adjusted non-GAAP net loss (see Table A-2) for fiscal 2017, excluding various items (separation charges, reserve for uncollectable sub-lease income, impairment charges, change in derivative warrant liabilities, change in contingent consideration obligation, loss on equity method investments, anticipated loss on sub-lease land, interest expense - amortization of debt discount, and valuation allowance for deferred tax assets), was $(1.8) million, or $(0.10) per basic and diluted share.

Adjusted EBITDA (see Table B) for fiscal 2018 was $1.3 million, compared to adjusted EBITDA of $3.5 million in fiscal 2017.

In addition to financial results reported in accordance with accounting principles generally accepted in the United States of America ("GAAP"), the Company has provided the following non-GAAP financial measures in this release and the accompanying tables: adjusted EBITDA, adjusted non-GAAP net income (loss) and adjusted earnings (loss) per share. S&W uses these non-GAAP financial measures internally to facilitate period-to-period comparisons and analysis of its operating performance and liquidity, and believes they are useful to investors as a supplement to GAAP measures in analyzing, trending and benchmarking the performance and value of the Company's business. However, these measures are not intended to be a substitute for those reported in accordance with GAAP. These measures may be different from non-GAAP financial measures used by other companies, even when similar terms are used to identify such measures.

For reconciliations of historical non-GAAP financial measures to the most comparable financial measures under GAAP, see Tables A-1, A-2 and B accompanying this release.

In order to calculate these non-GAAP financial measures, the Company makes targeted adjustments to certain GAAP financial line items found on its Consolidated Statement of Operations, backing out non-recurring or unique items or items that the Company believes otherwise distort the underlying results and trends of the ongoing business. The Company has excluded the following items from one or more of our non-GAAP financial measures for the periods presented:

Selling, general and administrative expenses; operating expenses. We exclude a portion of SG&A expense and operating expenses related to transaction expenses related to acquisitions and financings. Acquisition-related expenses include transaction fees, due diligence costs and other direct costs associated with our acquisitions. These amounts are unrelated to our core performance during any particular period and are impacted by the timing of the acquisition. We exclude acquisition-related

expenses from our SG&A expense and total operating expenses to provide investors a method to compare our operating results to prior periods and to peer companies, as such amounts can vary significantly based on the frequency of acquisitions and the magnitude of acquisition expenses. We also exclude a portion of SG&A expense and operating expenses related to employee separation costs and a reserve for uncollectible sub-lease income. The amounts are unrelated to our core performance during any particular period. We exclude employee separation related expenses and the reserve for uncollectible sub-lease income from our SG&A expense and total operating expenses to provide investors a method to compare our operating results to prior periods and to peer companies.

Impairment charges. We exclude an impairment charge of $319,000 related to the carrying value of certain stand establishment assets which were deemed impaired and uncollectible from a certain sub-leasee. This amount is a non-recurring charge and is unrelated to our core performance during any particular period, and therefore, we believe it is useful to exclude this amount in order to better understand our business performance and allow investors to compare our results with peer companies.

Changes in derivative warrant liabilities. Change in derivative warrant liabilities are related to the change in fair value of the warrants issued in conjunction with our Convertible Debentures issued in December 2014. These amounts are non-cash gains and/or losses, and are unrelated to our core performance during any particular period. We believe it is useful to exclude these amounts in order to better understand our business performance and allow investors to compare our results with peer companies.

Changes in contingent consideration obligations. Change in contingent consideration obligations is related to the change in fair value of the contingent consideration potentially owed as a result of the previously announced acquisitions. These amounts are non-cash gains and/or losses, and are unrelated to our core performance during any particular period. We believe it is useful to exclude these amounts in order to better understand our business performance and allow investors to compare our results with peer companies.

Loss on equity method investment. Losses from our equity method investment are related to our portion of losses incurred from our joint venture in Argentina. These amounts are unrelated to our core performance during any particular period, and therefore, we believe it is useful to exclude these amounts in order to better understand our business performance and allow investors to compare our results with peer companies.

Interest expense - amortization of debt discount. Amortization of debt discount and debt issuance costs are primarily related to our Convertible Debentures and warrants issued in December 2014 as well as our working capital lines of credit and term loans. These amounts are non-cash charges and are unrelated to our core performance during any particular period. We believe it is useful to exclude these amounts in order to better understand our business performance and allow investors to compare our results with peer companies.

Non-GAAP Tax Rate. The estimated non-GAAP effective tax rate adjusts the tax effect to quantify the tax consequences of the excluded non-GAAP items.

Descriptions of the non-GAAP financial measures included in this release and the accompanying tables are as follows:

Adjusted net income (loss) and non-GAAP earnings (loss) per share. We define non-GAAP net income (loss) as net income (loss) less non-recurring transaction charges, separation costs, reserves for uncollectible sub-lease income, impairment charges, change in derivative warrant liabilities, change in contingent consideration obligation, anticipated loss on sub-lease land, interest expense - amortization of debt discount, and loss on equity method investment. However, in order to provide a complete picture of our recurring core business operating results, we also exclude from non-GAAP net income (loss) the tax effects of these adjustments. We used an effective tax rate that we believe would be applied had our income approximated the non-GAAP net income (loss) for the presented periods. We caution investors that the tax effects of these adjustments are based on management's estimates. We believe that these non-GAAP financial measures provide useful supplemental information for evaluating our operating performance.

Adjusted EBITDA is a non-GAAP financial measure that we define as GAAP net income (loss), adjusted to exclude non-recurring transaction costs, separation costs, reserve for uncollectible sub-lease income, impairment charges, depreciation and amortization, non-cash stock-based compensation, foreign currency (gain) loss, change in derivative warrant liabilities, change in contingent consideration obligation, anticipated loss on sub-lease land, loss on equity method investment, interest expense - amortization of debt discount, interest expense, and provision (benefit) for income taxes. We believe that the use of adjusted EBITDA is useful to investors and other users of the Company's financial statements in evaluating our operating performance because it provides them with an additional tool to compare business performance across companies and across periods. We use adjusted EBITDA in conjunction with traditional GAAP operating performance measures as part of our overall assessment of our performance, for planning purposes, including the preparation of our annual operating budget, to evaluate the effectiveness of our business strategies and to communicate with our board of directors concerning our financial performance. Management does not place undue reliance on adjusted EBITDA as its only measure of operating performance. Adjusted EBITDA should not be considered as a substitute for other measures of financial performance reported in accordance with GAAP.
