Can ROA be negative?

Could you please elaborate on the possibility of a negative ROA, or Return on Assets? I understand that ROA is a financial ratio used to measure how efficiently a company is using its assets to generate profit. However, I'm curious about the scenarios where ROA could potentially be negative. Is it possible for a company to have a negative ROA, and if so, what might cause this to happen? Could you provide some real-world examples to help me better understand this concept?
