What could be a consequence faced by insiders disclosing information improperly?

Insiders who improperly disclose information, particularly material nonpublic information about a company, can face serious legal consequences. This includes the possibility of imprisonment or fines. The legal framework around insider trading is designed to protect the integrity of the financial markets and to ensure fair access to information among all investors. When insiders violate these legal boundaries, they undermine public trust in the market and can be subjected to penalties such as hefty fines and even prison time, depending on the severity of the offense.

The other options do not align with the legal realities associated with improper disclosures. Gaining a promotion or receiving general public acclaim would imply positive outcomes, which do not reflect the accountability that comes from violating insider trading laws. Similarly, a written apology would not be a typical response to such violations, as the consequences are generally punitive rather than reconciliatory.
