Note 1 - Organization and Description of Business

SenesTech, Inc. (the “Company”) was formed in July 2004 and incorporated in the state of Nevada. The Company subsequently reincorporated in the state of Delaware in November 2015. The Company has its corporate headquarters in Flagstaff, Arizona.

The Company has developed proprietary technology for managing animal pest populations through fertility control. The Company believes that its innovative non-lethal approach, targeting reproduction, is more humane, less harmful to the environment, and more effective in providing a sustainable solution to pest infestations than traditional lethal pest management methods. Its first fertility control product candidate, ContraPest, is marketed for use in controlling the rat population. The innovative compound is consumed by rats and leaves them non-reproductive without other observable side effects. The Company is pursuing regulatory approvals for ContraPest in various jurisdictions, including the United States (“U.S.”), India, Argentina and the European Union (“EU”). On August 23, 2015, the Company submitted ContraPest for registration with the U.S. Environmental Protection Agency (“EPA”), and the EPA granted registration approval for ContraPest effective August 2, 2016. Following regulatory approval for ContraPest, the Company plans to commercialize and distribute ContraPest by leveraging new and existing third party relationships with manufacturing, marketing and distribution partners in the U.S. and internationally.

Potential Need for Additional Capital

In the course of its research and development activities, the Company has sustained operating losses since its inception and expects such losses to continue for the near future. The Company’s ultimate success depends upon the outcome of a combination of factors, including: (i) the success of its research and development; (ii) regulatory approval and commercialization of ContraPest and its other product candidates; (iii) market acceptance and commercial viability of ContraPest and other products if the Company obtains the necessary regulatory approvals; (iv) the ability to market its products and establish an effective sales force and marketing infrastructure to generate significant revenue; (v) the ability to retain and attract key personnel to develop, operate and grow its business; and (vi) the timely and successful completion of additional financing as needed. The Company has funded its operations to date through the sale of convertible preferred stock and common stock, including an initial public offering of 1,875,000 shares of its common stock on December 8, 2016, debt financing, consisting primarily of convertible notes and, to a lesser extent, payments received in connection with research grants and licensing fees. As of March 31, 2017, the Company had cash and cash equivalents and highly liquid investments of $8,324. Based upon its current operating plan, the Company expects that cash and cash equivalents and highly liquid, short term investments at March 31, 2017, in combination with anticipated revenue, will be sufficient to fund its current operations for the foreseeable future. However, for reasons detailed above, the Company may require additional capital and would have to continue to fund its operating losses and research and development activities in the near term by issuing additional debt and equity instruments. If such equity or debt financing is not available at adequate levels, the Company will need to reevaluate its plans.
