Simulations Plus Announces Next Quarterly Cash Dividend

Company declares cash dividend of $0.05 per share

LANCASTER, CA, July 27, 2012 – Simulations Plus, Inc. (NASDAQ: SLP), a leading provider of simulation and modeling software for pharmaceutical discovery and development, today announced that its board of directors has declared its next ongoing quarterly cash dividend of $0.05 per share to its shareholders will be distributed on Friday, August 10, 2012, for shareholders of record as of Tuesday, August 7, 2012.

Walt Woltosz, chairman and chief executive officer of Simulations Plus, said: “As we announced previously, the board of directors decided that an ongoing quarterly cash dividend is appropriate at this time. This next dividend distribution will be our third after the initial distribution in March of this year. As reported in our third quarter conference call on Thursday, July 12, our cash position is as strong as it was prior to the last dividend distribution, therefore paying the dividend has not prevented us from adding cash to our balance sheet.”
