Depends on the company. Some asset heavy companies (think railroads, commercial REITs) pay steady dividends, and are extremely unlikely to just go under without warning.

The water utility for my country's capital is a publicly traded company for some reason. The only way they're going out of business is if people stop using water or water stops existing in the area.

That can honestly be considered a forever stock as far as I can tell. Dividends aren't super high but that's because they're constantly saving up half the profit for future infra work.
