New major risk - Revenue and earnings growth Revenue has declined by 28% over the past year. This is considered a major risk.

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.
