There are many risks that businesses face, including:
Competition risk - there could be another business that draws customers away from your company.
Economic risk- if the economy is doing poorly, it could increase costs or reduce sales
Reputation - if someone posts a bad review online, how will that effect your sales?
Legal/Compliance issues- you have to comply with industry regulations and laws, and there is great risk to you and the business if you break these rules
Resources risk - if you rely on a specific material to run your business and that material isn't available you could be in trouble (ex. if the orange crop is wiped out by a hurricane, orange juice makers could be in trouble)
