Simulations Plus, Inc. (NASDAQ: SLP), a leading provider of simulation and modeling software for pharmaceutical discovery and development, today announced that it has entered into a Stock Purchase Agreement (the “Agreement”) with DILIsym Services, Inc. of Research Triangle Park, North Carolina.

Pursuant to the Agreement, upon closing, DILIsym Services, Inc. (“DILIsym Services”) will become a wholly owned subsidiary of Simulations Plus, Inc. (“Simulations Plus”) and will continue to operate under the DILIsym Services name. This accretive acquisition will result in the total number of Simulations Plus employees increasing from 68 to 79, and is expected to add more than $3 million to the revenues of the combined company in the coming fiscal year 2018.

Walt Woltosz, chairman and chief executive officer of Simulations Plus, said, “This is an exciting step forward for both Simulations Plus and DILIsym Services. The combination will significantly strengthen our software and consulting services efforts, and bolster our management team as well. I am pleased that the existing management team of DILIsym Services will remain with the company. The officers of DILIsym Services will be Dr. Brett Howell, who will serve as president, Dr. Scott Siler, who will serve as chief scientific officer, and Dr. Bud Nelson, who will serve as director of operations. In the aggregate, these three leaders have more than 50 years of relevant experience. I will remain as Chairman and CEO of Simulations Plus, overseeing all three divisions (Simulations Plus, DILIsym Services, and Cognigen Corporation). In addition, Professor Paul Watkins, M.D., of the University of North Carolina, internationally recognized as the foremost authority on drug-induced liver injury, will continue as the director of the DILI-sim Initiative Consortium and chairman of the Initiative’s Scientific Advisory Board. This consortium is an international group of twelve pharmaceutical companies that fund the ongoing development of the DILIsym® software.”

Dr. Brett Howell added, “Drug-induced liver injury (DILI) is a rare adverse drug reaction and is the leading cause for acute liver failure in the United States. It is also the most common factor that compels regulatory actions related to drugs, such as denial of approval or restriction of indications for using a drug. It is a prime area of concern for the U.S. Food and Drug Administration and other regulatory agencies worldwide. The DILIsym® software is the most advanced mechanistic mathematical model of drug-induced liver injury, simulating the mechanistic interactions and events from drug administration through the progression of liver injury and regeneration. DILIsym Services scientists have supported our customers to present results of DILIsym simulations to several regulatory agencies. We are excited to join Simulations Plus and take advantage of the various synergies that exist between the organizations.”

John Kneisel, chief financial officer of Simulations Plus, added, “We expect this deal will be immediately accretive to both revenues and earnings, and will not affect our ability to continue to distribute dividends. Of course, the Board of Directors determines the dividend each quarter and has the option of continuing, increasing, decreasing, or eliminating it at any time to meet the cash needs of the business.”

The Agreement

The Agreement calls for the acquisition of DILIsym Services by Simulations Plus with DILIsym Services becoming a wholly owned subsidiary of Simulations Plus following the closing of the acquisition, which is subject to final due diligence and other closing conditions. The closing date of the proposed acquisition is anticipated to be June 1, 2017.

Under the terms of the Agreement, Simulations Plus will pay the shareholders of DILIsym Services cash consideration of up to $10 million, comprised of $5 million up front plus an earn-out of up to an additional $5 million over the next three years, based on the profitability of the DILIsym Services division. The Agreement provides that $1 million of the total up-front consideration will be held back for 18 months to satisfy any indemnifiable claims that may arise pursuant to the terms of the Agreement.

Excel Partners, an investment bank with offices in New York and Los Angeles, acted as exclusive financial advisor to Simulations Plus in connection with this transaction. Procopio, Cory, Hargreaves & Savitch LLP served as legal counsel to Simulations Plus in connection with this transaction.
