Mark Wong, president and chief executive officer of S&W Seed Company, commented, "We continue to make progress on the strategy I laid out when I took over as CEO in June 2017. During the last couple of months, our strategic analysis has identified key markets for initial expansion of our hybrid sorghum and sunflower seed programs to maximize return, while managing our risk profile. We have also advanced our focus on key trait technologies within our alfalfa, sorghum, and sunflower programs where we believe there are underserved opportunities where we can add value to farmers and end customers. Finally, we are engaging in discussions on a future direction of our stevia program that we believe will warrant the highest probable outcome for success. These strategic evaluations and decisions were made against the backdrop of continued improvements within our historical operations where gross profit margins increased by 130 basis points to 22.8%, from the second quarter of the prior year."

"During the second quarter we executed against our distribution plan with Pioneer, to which we shipped approximately $15.3 million of seed. The Saudi Arabian markets continue to remain uncertain as dairy and hay farmers determine what the new equilibrium in the market will look like. We believe the Saudi consumers will continue to demand fresh milk and forages for their livestock, which will require the importation of alfalfa hay from surrounding regions in the Middle East and Northern Africa (MENA), as well as regions around the world such as North and South America, to feed local Saudi-based livestock. Ultimately, we believe the global alfalfa markets will return to historical levels, and with our vast distribution network around the world, we believe we are positioned to maintain and grow our market share in the coming years."

Wong concluded, "I am pleased with the progress we have made in our strategy to balance the long-term focus on trait improvements and new crop introductions, such as sorghum, sunflower and stevia, with a near-term focus on becoming a more efficient and successful production, marketing and sales organization within alfalfa. We continued to strengthen the balance sheet with a successfully completed rights offering in December 2017, which, when coupled with our private placement in July 2017, has significantly improved our balance sheet position. I want to thank our existing stockholders for their continued support and look forward to driving value for them in the years to come."

Based on information currently available to management, S&W expects to deliver results at the low end of the range of previous guidance for fiscal 2018, which was approximately $75 to 80 million in revenue and $4.0 and $5.5 million in Adjusted EBITDA.

For the second quarter of fiscal year 2018 ended December 31, 2017, S&W reported revenue of $20.5 million compared to revenue of $24.2 million in the second quarter of fiscal 2017. The decrease was largely attributable to a decrease of sales directed to the Saudi Arabia markets as a result of water regulations in Saudi Arabia, coupled with timing of shipments to the domestic market.

Gross margins during the second quarter of fiscal 2018 improved 130 basis points to 22.8% compared to gross margins of 21.5% in the second quarter of fiscal 2017. This improvement in gross profit margins was primarily due to product sales mix during the current period where we had a higher concentration of sales, as a percentage of total revenue, to DuPont; coupled with reductions of product costs of proprietary seed. This improvement in margin is consistent with management's previously discussed initiatives to drive improvements in gross margins.

Operating expenses (see Table A-1) during the second quarter of fiscal 2018 were $4.16 million, compared to $4.18 million in the second quarter of fiscal 2017.

GAAP net loss for second quarter of fiscal 2018 was $(400,000), or $(0.02) per basic and diluted share, compared to GAAP net income of $1.2 million, or $0.07 per basic and $0.01 per diluted share, in the second quarter of fiscal 2017.

Adjusted non-GAAP net loss (see Table A-1) for the second quarter of fiscal 2018, excluding certain items (transaction costs, change in derivative warrant liabilities and interest expense - amortization of debt discount), was $(20,000), or $0.00 per basic and diluted share. Adjusted non-GAAP net income (see Table A-1) for the second quarter of fiscal 2017, excluding various items (change in derivative warrant liabilities, change in contingent consideration obligation, and interest expense - amortization of debt discount), was $467,000, or $0.03 per basic and diluted share.

Adjusted EBITDA (see Table B) for the second quarter of fiscal 2018 was $1.6 million, compared to adjusted EBITDA of $2.2 million for the second quarter of 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.

Additionally, the Company has not reconciled its adjusted EBITDA outlook for fiscal 2018 to net income (loss) because it does not provide an outlook for the other line items that are reconciling items between net income (loss) and adjusted EBITDA. As items that impact net income (loss) are out of the Company's control and cannot be reasonably predicted, the Company is unable to provide such an outlook. Accordingly, reconciliation of adjusted EBITDA outlook to net income (loss) for fiscal 2018 is not available without unreasonable effort.  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.

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 to DuPont Pioneer and the sellers of SVG Genetics 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 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, change in derivative warrant liabilities, change in contingent consideration obligation, 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 transaction costs, depreciation and amortization, non-cash stock-based compensation, foreign currency (gain) loss, change in derivative warrant liabilities, change in contingent consideration obligation, loss on equity method investment, interest expense - amortization of debt discount, interest expense - convertible debt and other, 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.
