10 Camelina/Biofuels JV S&W Seed Company (Nasdaq: SANW) JV with Shell (NYSE: SHEL) Worldwide JV (named Vision Bioenergy Oilseeds LLC) with Shell plc (for the purpose of developing novel plant genetics, increasing oil seed cover crop acres and managing the crushing of these new acres for biofuel, green diesel, and jet fuel production. Shell plc operates as an energy and petrochemical company operating through Integrated Gas, Upstream, Marketing, Chemicals and Products, and Renewables and Energy Solutions segments. Commercially viable oilseed with the potential to be a sustainable feedstock source for the energy transition. Camelina also is recognized as a low greenhouse gas cover crop in the US. Cover crops are planted between main crop growing seasons, with the aim of not influencing the price or availability of crops grown for food and feed. Using effective controls and management, Camelina has the potential to provide sustainable feedstocks, and create social and environmental co-benefits by diversifying farmers' income streams and reducing soil erosion. Biofuels, such as those made from Camelina oil, may be an effective way to help decarbonize customers in hard-to-abate sectors, where energy density in fuels is key, including the aviation, marine, and heavy-duty road transport sectors. Shell and the JV have executed an Offtake Agreement pursuant to which Shell will purchase the available Camelina grain and use Camelina oil to produce sustainable biofuels. Initial grain production expected in late calendar 2023. $20 M $25 M 66% S&W to receive $13 million cash from Shell ($7 million up front and another $6 million due in Feb. 2024) plus $7 million for Nampa facility debt pay off.

S&W will leverage its proprietary stevia plant portfolio and production techniques to supply Ingredion and its PureCircle by Ingredion group of companies, with high-quality, U.S.-sourced stevia plants. S&W has developed unique, non-GMO, all-natural stevia varieties over the past ten years utilizing our proprietary plant breeding program. The size of the global stevia market is estimated to grow to $1.6B by 2028 according to LEK and Ingredion’s internal analysis. Currently, due to historical constraints with climate and harvesting techniques, the vast majority of stevia is produced outside the United States. Recently, S&W made what it believes is a significant leap forward by validating efficacy of stevia production in the southeastern United States. By leveraging a unique seed-to-plant process and mechanical harvesting system, S&W expects to reduce overall production costs. Method is also intended to allow the stevia to function as a green cover crop, helping to sequester carbon.

Appendix

25 Non-GAAP Financial Measures S&W Seed Company (Nasdaq: SANW) Non-GAAP Financial Measures In addition to financial measures included in this presentation that are calculated 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 presentation: adjusted EBITDA. 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. Adjusted EBITDA is a non-GAAP financial measure that we define as GAAP net income (loss), adjusted to exclude restructuring charges, non-recurring acquisition-related expenses, depreciation and amortization, impairment charges, non-cash stock-based compensation, foreign currency (gain) loss, change in derivative warrant liabilities, change in estimated value of assets held for sale, reduction of anticipated loss on subleased land, change in contingent consideration obligations, dividend accrued for participating securities and accretion, loss on extinguishment of debt, gain on sale of marketable securities, 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 this non-GAAP measure 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 these non-GAAP measures as their only measures of operating performance. These non-GAAP measures should not be considered as substitutes for other measures of financial performance reported in accordance with GAAP. We have not reconciled expected 2023 adjusted EBITDA to net income (loss) because the Company has not provided assumptions for the other line items that are reconciling items, including depreciation, amortization, interest expense and stock-based compensation, among others. As these items are out of the Company's control and cannot be reasonably predicted, the Company is unable to provide such an outlook. Accordingly, reconciliation of these non-GAAP measures to their most directly comparable GAAP measures is not available without unreasonable effort. We have not reconciled our outlook for adjusted EBITDA for fiscal 2023 to net income (loss) because the reconciling line items that impact net income (loss), including interest expense, non-cash stock-based compensation, and foreign currency (gain) loss, among others are uncertain or out of our control and cannot be reasonably predicted. The actual amount of these items during fiscal 2023 will have a significant impact on net income (loss). Accordingly, a reconciliation of these non-GAAP measures to their most directly comparable GAAP measures is not available without unreasonable efforts.
