SACRAMENTO, California - May 9, 2018 - S&W Seed Company (Nasdaq: SANW) today announced financial results for the third quarter of fiscal year 2018 ended March 31, 2018.

Mark Wong, president and chief executive officer of S&W Seed Company, commented, "Progress was made during the third quarter on certain key initiatives of our go forward strategy to transition S&W into a more diversified middle market agricultural company. Specifically, we intensified our efforts in our stevia program through expanded collaborations, both on the commercialization and development front. We believe there is increasing interest in the marketplace for minimally processed stevia-based sweeteners from producers with U.S.-based production capabilities. We also believe our current stevia varieties, as well as varieties we are developing in collaboration with our partners, are ideally positioned to capitalize on these trends. Additionally, the appointment to our board of directors of Alan Willits has enabled us to enhance our stevia commercialization knowledge. Mr. Willits is a 38-year executive with Cargill, is the chairman of Cargill Asia Pacific and leads Cargill's Agricultural Supply Chain business in the Asia Pacific region, the region in which stevia is currently most prevalently grown. We look forward to continued progress on this key value enhancing component of our business in the quarters to come."

"I am pleased with the execution during the third quarter within our domestic alfalfa operations. Revenues during the third quarter increased by 9.2% over the third quarter of the prior year, driven primarily by timing of shipments under our distribution agreement with DuPont Pioneer, while gross profit margins improved by 140 basis points to 29.0%. We plan to stay focused on maintaining strong pricing, coupled with reductions of production costs of proprietary seed, where possible. As we have reported during the last year, the Saudi Arabian market conditions continue to be difficult and it remains uncertain as to when a return to market equilibrium will occur. While the elevated inventory levels in the distribution channel appear to have decreased, dealers and distributors in the region remain apprehensive to take on additional supply until a perceived equilibrium in the Saudi Arabian market is reached. We therefore are further reducing our expectations for sales in the Saudi Arabian market in the near term."

Mr. Wong concluded, "Our management team and advisors, along with our board of directors, are aligned on our go forward strategy. We will work to continue our pathway towards enhancing our trait technology capabilities to bring products to market where we can capture an increasing portion of the seed economics; build out our alfalfa, sorghum and sunflower programs with an emphasis on countries in which we believe the regulatory, economic and political environments allow for a more stable market to operate in, such as the United States and Australia; and commercialize our stevia program. We believe these actions will position the company for future success, while minimizing risks to the extent possible. I look forward to the further execution on this strategy in the upcoming quarters."

Third Quarter Fiscal Year 2018 Financial Highlights and Recent Corporate Developments:

• Revenue during the third quarter of fiscal 2018 was $22.9 million compared to $21.0 million in the third quarter of the prior year;
• Gross profit margins improved by 140 basis points to 29.0%, compared to gross profit margins of 27.6% in the third quarter of fiscal 2017 as S&W continues to execute on its gross margin expansion initiatives;
• Adjusted EBITDA (see Table B) increased to $3.1 million for the third quarter of fiscal 2018, compared to $2.7 million in the third quarter of fiscal 2017;
• GAAP net income (see Table A-1) of $1.8 million, or $0.07 per basic and diluted share during the third quarter of fiscal 2018, compared to GAAP net income of $1.3 million, or $0.07 per basic and $0.02 per diluted share, in the third quarter of fiscal 2017;
• Adjusted non-GAAP net income (see Table A-1) of $1.9 million, or $0.08 per basic and diluted share during the third quarter of fiscal 2018, compared to adjusted non-GAAP net income of $830,000, or $0.05 per basic and diluted share, in the third quarter of fiscal 2017; and
• In April 2018, acquired a selection of sorghum germplasm to expand our portfolio of sorghum products to include biofuel types.

Based on information currently available to management, S&W expects to report revenue for fiscal 2018 between $65 and $70 million as we are further reducing our expectations for sales into the Saudi Arabian market in the near term. Adjusted EBITDA is expected to be between $2.0 and $3.5 million on improved gross margins offset by decreased sales into Saudi Arabia.

For the third quarter of fiscal year 2018 ended March 31, 2018, S&W reported revenue of $22.9 million compared to revenue of $21.0 million in the third quarter of fiscal 2017. The increase was largely attributable to increased shipments to DuPont Pioneer under the Company's distribution agreement, offset by decreases to Saudi Arabia as a result of water regulations in the country.

Gross margins during the third quarter of fiscal 2018 improved 140 basis points to 29.0% compared to gross margins of 27.6% in the third 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 Pioneer; 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.

Adjusted operating expenses (see Table A-1) during the third quarter of fiscal 2018 were $4.6 million, compared to $4.2 million in the third quarter of fiscal 2017. Included in the third quarter of the prior year was 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-lessee. Including this impairment charge, total operating expenses in the third quarter of the prior year were $4.6 million.

GAAP net income for third quarter of fiscal 2018 was $1.8 million, or $0.07 per basic and diluted share, compared to GAAP net income of $1.3 million, or $0.07 per basic and $0.02 per diluted share, in the third quarter of fiscal 2017.

Adjusted non-GAAP net income (see Table A-1) for the third quarter of fiscal 2018, excluding certain items (transaction costs and interest expense - amortization of debt discount), was $1.9 million, or $0.08 per basic and diluted share. Adjusted non-GAAP net income (see Table A-1) for the third quarter of fiscal 2017, excluding various items (impairment charges, change in derivative warrant liabilities, change in contingent consideration obligation, loss on equity method investment, and interest expense - amortization of debt discount), was $830,000, or $0.05 per basic and diluted share.

Adjusted EBITDA (see Table B) for the third quarter of fiscal 2018 was $3.1 million, compared to adjusted EBITDA of $2.7 million for the third 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.

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, impairment 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 non-recurring transaction costs, impairment charges, 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, 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.
