Currently, the following risks have been identified for the company: Major Risks Earnings have declined by 9.8% per year over the past 5 years. Shareholders have been substantially diluted in the past year (49% increase in shares outstanding). Minor Risks Share price has been volatile over the past 3 months (13% average weekly change).

New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 49% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Earnings have declined by 5.3% per year over the past 5 years. Shareholders have been substantially diluted in the past year (49% increase in shares outstanding). Minor Risks Revenue is less than US$5m (₩4.6b revenue, or US$3.1m).

New major risk - Revenue and earnings growth Earnings have declined by 5.3% per year over the past 5 years. This is considered a major risk. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. If profits are declining over an extended period, then in most cases the share price will decline over time unless the company can turn around its fortunes. A trend of falling earnings can be very difficult to turn around. If the company is well already established it may also be a sign the company has matured and is in decline. In addition, if the company pays dividends it will also likely need to reduce or cut them, striking a dual blow to total shareholder returns. Currently, the following risks have been identified for the company: Major Risks Share price has been highly volatile over the past 3 months (11% average weekly change). Earnings have declined by 5.3% per year over the past 5 years. Shareholders have been substantially diluted in the past year (32% increase in shares outstanding). Minor Risks Revenue is less than US$5m (₩4.6b revenue, or US$3.1m). Market cap is less than US$100m (₩46.5b market cap, or US$31.7m). Duyuru • Nov 26

New minor risk - Revenue size The company makes less than US$5m in revenue. Total revenue: ₩5.3b (US$3.6m) This is considered a minor risk. Companies with a small amount of revenue are most likely businesses that have not yet released a product to market or are simply a very small company without a wide reach. Either way, risk is elevated with these companies because there is a chance the product may not come to fruition or the company's addressable market or demand may not be as large as expected. In addition, if the company's size is the main factor, it is less likely to have many investors and analysts following it and scrutinizing its performance and outlook. Currently, the following risks have been identified for the company: Major Risks Share price has been highly volatile over the past 3 months (13% average weekly change). High level of non-cash earnings (22% accrual ratio). Minor Risks Revenue is less than US$5m (₩5.3b revenue, or US$3.6m). Market cap is less than US$100m (₩54.9b market cap, or US$37.4m).
