The statistical population of this study is all companies listed on the Tehran Stock Exchange from 2015 to 2021 and the number of samples is 105 companies. The regression analysis method and Ivory statistical software were used to analyze the research data.

The selection of large auditors by companies with political connections has no significant relationship with profit stability. However, the longer the term of the CEO of companies with political connections increases, the more stable the profit. The results generally indicate a significant relationship between profit stability, institutional oversight, and various types of political communication.
