As a public company, it incurs significant compliance costs and management time. Future sales of common stock could cause price declines, and the absence of cash dividends means capital appreciation is the sole source of gain for stockholders - The trading price of common stock is highly volatile and subject to wide fluctuations due to various factors, including clinical results, regulatory approvals, competition, and economic conditions[411](index=411&type=chunk)[412](index=412&type=chunk) - The company does not anticipate paying cash dividends in the foreseeable future; capital appreciation will be the sole source of gain for stockholders[413](index=413&type=chunk) - An active trading market for common stock may not be sustained, limiting investors' ability to resell shares[416](index=416&type=chunk) - Lack of equity research analyst coverage or negative evaluations could cause the stock price to decline[417](index=417&type=chunk) - Operating as a public company incurs significant legal, accounting, and compliance costs (e.g., Sarbanes-Oxley Act), diverting management time and resources[418](index=418&type=chunk)[419](index=419&type=chunk) - Volatility in stock price may lead to securities litigation, incurring substantial costs and diverting management's attention[420](index=420&type=chunk)[422](index=422&type=chunk) - Future sales of common stock by the company or insiders, or shares issued upon option exercise, could cause the stock price to decline[423](index=423&type=chunk) [ITEM 6.
