SACRAMENTO, California – February 28, 2018

S&W Seed Company (Nasdaq: SANW) today announced that the U.S. Patent and Trademark Office has granted S&W a patent covering its unique stevia plant variety ‘SW 227.’ S&W believes that its SW 227 variety has an excellent, sweet leaf taste with very low bitterness and aftertaste, and is late flowering, with high plant vigor characterized by extensive stooling and branching, enhanced dry leaf yields and leaves having an average rebaudioside A content of 10.7%.

The patent was issued on February 20, 2018, as U.S. Plant Patent PP28977. The term of an issued plant patent is the same as that of an issued utility patent, which is 20 years from the patent’s filing date. Based on the filing date, the patent for SW 227 will expire on March 31, 2036. This is S&W’s fourth patent granted for its unique stevia varieties.

Mark Wong, president and chief executive officer of S&W, said, “We are dedicated to developing stevia as a U.S.-grown crop. All stevia is currently produced in Asia. In speaking with potential stevia customers, we believe that there is significant demand for stevia produced in the United States and that S&W is uniquely positioned to develop this market opportunity. Our goal is to use our proprietary germplasm in stevia and leverage our farmer grower network to create a U.S.-based stevia production industry for high-quality stevia sweetener with superior taste profiles to supply major customers in the U.S. market.”

About S&W’s Unique Stevia Varieties

Fresh and Dry Leaf Market

Stevia variety ‘SW 201’, S&W’s first patented variety for the fresh and dry leaf market, is not only believed to have a sweet taste with very little bitterness and aftertaste, but exhibited more Reb-A, less stevioside, more total steviol glycosides, a higher Reb-A to stevioside ratio, and a higher percentage of Reb-A to total steviol glycosides than the comparison samples from common varieties.

S&W believes that Stevia variety ‘SW 227’ has an excellent, sweet leaf taste with very low bitterness and aftertaste, and is late flowering, with high plant vigor characterized by extensive stooling and branching, enhanced dry leaf yields and leaves having an average Reb-A content of 10.7%.

Commercial Processing Market

Stevia variety ‘SW 107’ exhibited increased concentrations of Reb-A sweetener and higher leaf mass production than the comparison samples of currently available varieties. SW 107 has been bred to address commercial processing markets in North America, South America and other regions of the world that have climates suitable for it.

S&W believes that Stevia variety ‘SW 129’ has very sweet leaves with high levels of steviol glycosides, very low bitterness and aftertaste with excellent overwintering, high plant vigor, high leaf yield and late flowering. S&W believes that SW 129 is ideally suited for commercial level stevia extraction due to these enhanced characteristics.
