- Risks Related to Our Business and Industry
- Our business is intensely competitive, and our revenues are unpredictable as a small company.
- We rely heavily on our ability to attract international customers for business and expect to continue to rely on our ability to attract international customers in the future.
- Government Regulation
- Nuclear Power, Fossil Fuel and Renewal Energy
- Nuclear Fusion Power Research and Prototypes
- Opponents to Nuclear Energy are formidable due to concerns over safety.
- Continued growth of CANDU reactors and rapid development of next generation Molten Salt (MSR) and Liquid-Fluoride Thorium Reactors (LFTR).
- Failure to make accretive acquisitions and successfully integrate them could adversely affect our future financial results.
- We have filed a provisional patent for our product based on our tritium products but hold no current patents on our products, and our business employs proprietary technology and information which may be difficult to protect and may infringe on the intellectual property rights of third parties.
- Our failure to obtain capital may significantly restrict our proposed operations.
- We are subject to the risk that certain key personnel, including key employees named below, on whom we depend, in part, for our operations, will cease to be involved with us. The loss of any these individuals would adversely affect our financial condition and the results of our operations.
The other 15 risks
- The loss of any of our executive officers could adversely affect our business.
- Competition from other radiation detection or related companies could result in a decrease of our business and a decrease in our financial performance.
- Regulations, including those contained in and issued under the Sarbanes-Oxley Act of 2002 (“SOX”) and the Dodd–Frank Wall Street Reform and Consumer Protection Act of 2010 (“Dodd-Frank”), increase the cost of doing business and may make it difficult for us to retain or attract qualified officers and directors, which could adversely affect the management of our business and our ability to obtain or retain listing of our Common Stock.
- Limitations on director and officer liability and our indemnification of our officers and directors may discourage stockholders from bringing suit against a director.
- We may incur a variety of costs to engage in future acquisitions of companies, products or technologies, to grow our business, to expand into new markets, or to provide new services. As such, the anticipated benefits of those acquisitions may never be realized.
- We must attract and retain skilled personnel. If we are unable to hire and retain technical, sales and marketing, and operational employees, our business could be harmed.
- Our failure to manage growth effectively could harm our ability to attract and retain key personnel and adversely impact our operating results.
- If we obtain financing, existing shareholder interests may be diluted.
- Risks Related to Our Common Stock
- Our stock price may be volatile or may decline regardless of our operating performance, and the price of our common stock may fluctuate significantly.
- Our Common Stock is subject to risks arising from restrictions on reliance on Rule 144 by shell companies or former shell companies.
- If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.
- Our management and other affiliates have significant control of our Common Stock and could control our actions in a manner that conflicts with the interests of other stockholders.
- Penny Stock Considerations
- Failure to achieve and maintain effective internal controls in accordance with Section 404 of the Sarbanes-Oxley Act of 2002 could have a material adverse effect on our business and operating results. In addition, current and potential stockholders could lose confidence in our financial reporting, which could have an adverse effect on our stock price.
- We do not expect to pay any cash dividends for the foreseeable future.
