Oragenics to Join the Russell Microcap® Index

TAMPA, Fla.-- Oragenics, Inc. (NYSE MKT:OGEN), a healthcare company focused on becoming the world leader in novel antibiotics against infectious disease and probiotcs for oral health, announced today that it will be included in the Russell Microcap Index when Russell Investments reconstitutes its comprehensive set of U.S. and global equity indexes on Friday, June 28, 2013, according to a preliminary list of additions posted June 21^st on www.russell.com/indexes.

Dr. John N. Bonfiglio, Chief Executive Officer of Oragenics, said, “On the heels of listing on NYSE MKT in May, we see the addition to the Russell Microcap Index as a reflection of Oragenics’ positive momentum. The inclusion in the index marks another milestone for the Company as we garner greater investor awareness for our lantibiotics and oral probiotics business segments.”

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. Russell calculates more than 700,000 benchmarks daily covering approximately 98 percent of the investable market globally, 80 countries and more than 10,000 securities. Approximately $4.1 trillion in assets are benchmarked to the Russell Indexes.

Annual reconstitution of Russell Indexes captures the 4,000 largest U.S. stocks as of the end of May, ranking them by total market capitalization to create the Russell 3000® Index and Russell Microcap Index. These investment tools originated from Russell's multi-manager investment business in the early 1980s when the company saw the need for a more objective, market-driven set of benchmarks in order to evaluate outside investment managers. Membership in the Russell Microcap Index, which remains in place for one year, means automatic inclusion in the appropriate growth and value style indexes. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes
