Note 1. Organization and Basis of Presentation

Background

Champions Oncology, Inc. (the “Company”), is engaged in the development of advanced technology solutions and services to personalize the development and use of oncology drugs. The Company’s Tumorgraft Technology Platform is a novel approach to personalizing cancer care based upon the implantation of human tumors in immune-deficient mice. The Company uses this technology to derive revenue for two customer groups: Personalized Oncology Solutions (“POS”) and Translational Oncology Solutions (“TOS”). POS assists physicians in developing personalized treatment options for their cancer patients through tumor specific data obtained from drug studies and related personalized oncology services. The Company’s TOS business offers a technology platform to pharmaceutical and biotechnology companies using proprietary Tumorgraft studies, which have been shown to be predictive of how drugs may perform in clinical settings.

The Company has two operating subsidiaries: Champions Oncology (Israel), Limited and Champions Biotechnology U.K., Limited. For the years ended April 30, 2012 and 2011, there were no material revenues earned by these subsidiaries.
