So if you think your company's publicly traded shares may have many foreign owners, you get the FCC to increase the limits of foreign ownership.
Which is what they're doing, as reported in this linked article:
Audacy Asks For Permission To Increase Foreign Ownership Levels.
The next step in Audacy’s financial restructuring is in the hands of the Federal Communications Commission. The company has petitioned the FCC to allow it to increase its foreign ownership
It's not really an FCC matter, but for the state department and Team Telecom to investigate, if any foreign investors are in countries that are security risks.
Audacy calculates foreign individuals and entities would hold approximately 27.2% of the company’s equity. That is above the 25% threshold allowed, and so it must seek approval from the FCC before the maneuver is executed. Audacy is also building in a bit of headroom to bring on other offshore investors, requesting in its petition that it be allowed to go as high as 49.99%.
