ORGANIZATION AND LINES OF BUSINESS	ORGANIZATION AND LINES OF BUSINESS Organization Simulations Plus, Inc. (“Simulations Plus”) was incorporated on July 17, 1996. In September 2014, Simulations Plus acquired all of the outstanding equity interests of Cognigen Corporation (“Cognigen”) and Cognigen became a wholly owned subsidiary of Simulations Plus. In June 2017, Simulations Plus acquired DILIsym Services, Inc. (“DILIsym”) as a wholly owned subsidiary. In April 2020, Simulations Plus acquired Lixoft, a French société par actions simplifiée (“Lixoft” or “SLP France”), as a wholly owned subsidiary pursuant to a stock purchase and contribution agreement. In June 2023, Simulations Plus acquired Immunetrics, Inc. (“Immunetrics”) as a wholly owned subsidiary through a reverse triangular merger. (Simulations Plus together with its subsidiaries, collectively, the “Company,” “we,” “us,” “our”). Effective September 1, 2021, the Company merged both Cognigen and DILIsym with and into Simulations Plus through short-form mergers (the “Mergers”). To effectuate the Mergers, the Company filed Certificates of Ownership with the Secretaries of State of the states of Delaware (Cognigen’s and DILIsym’s state of incorporation) and California (Simulation Plus’ state of incorporation). Consummation of the Mergers was not subject to approval of the Company’s stockholders and did not impact the rights of the Company’s stockholders. On December 20, 2022, Simulations Plus International, Inc. (“SLPI”), a Delaware corporation, was created as a wholly owned subsidiary of Simulations Plus in order to facilitate future international acquisitions, if any, and global integrations. In furtherance of this objective, the Company added the trade name “SLP France” to Lixoft, and on April 25, 2023, Simulations Plus transferred its ownership of SLP France to SLPI pursuant to a contribution and acceptance agreement, resulting in SLP France becoming a wholly owned subsidiary of SLPI. The transfer did not impact the rights of the Company’s stockholders. Effective September 1, 2023, the Company merged Immunetrics with and into Simulations Plus through a short-form merger (the “Merger”). To effectuate the Merger, the Company filed Certificates of Ownership with the Secretaries of State of the states of Delaware (Immunetrics’ state of incorporation) and California (Simulation Plus’ state of incorporation). Consummation of the Merger was not subject to approval of the Company’s stockholders and did not impact the rights of the Company’s stockholders. At the beginning of fiscal year 2024, in order to create a more integrated and cohesive company, the Company reorganized its internal structuring to move away from divisions based on its prior acquisitions and to instead divide the internal structure into business units organized around key product and service offerings that the Company provides, which include: •Clinical Pharmacology and Pharmacometrics (“CPP”); •Quantitative Systems Pharmacology (“QSP”); •Physiologically based pharmacokinetics (“PBPK”); •Cheminformatics; and •Regulatory Strategies.
