A trio of media firms stand to lose their NYSE-traded status due to non-compliance with exchange regulations. Bear in mind that there’s a big gap between being in violation and actually getting kicked off the exchange, as companies have all kinds of ways of delaying and drawing out the process.

Journal Register: Newspaper publisher Journal Register (NYSE: JRC) has been given a delisting notice from the NYSE, as its shares have traded below $1.00 for 30 consecutive days. It recently closed at $.52, down from a one-year high of $6.48. The company has 10 days to announce a plan to increase its share price (a reverse split is a possibility) and then another six months to actually implement that plan. Statement

—Meanwhile NYT reports that the company has hired investment bank Lazard to explore some sort of restructuring. It’s not exactly clear what the company has in mind, but a bankruptcy filing is a possibility, given the company’s struggling operations and high debt load.

Sun-Times: Sitting in the same boat, Chicago-based Sun-Times Media Group has been given a non-compliance warning from the NYSE, because its market cap and stockholders equity have been below $75 million for thirty trading days. The company, which made the announcement Friday after the bell, has 45 days to submit a turnaround plan that it can execute within 18 months. The company said back in February that it was exploring strategic alternatives. Release.

Charter (NSDQ: CHTR) Communications: The struggling cable operator hasn’t received a warning yet, but its stock last touched the key $1.00 level on March 3, over a month ago. According to MultiChannel News, Charter has struggled with its listing status in the past. In 2003, it traded sub $1.00 for 21 days, and in 2005, it was short one board director. The company will hit the 30 day trading benchmark on April 15.
