From the article:

“Q” Always Stays
The “Q” is never actually removed from the stock in question’s ticker symbol because it differentiates the pre-bankruptcy stock from the post-bankruptcy stock. This letter remains an important part of the stock’s ticker symbol; otherwise, potential investors would not be aware that they are purchasing stock involved in a bankruptcy that might become worthless on the markets once new stock is issued under the reorganized corporation.
