CSG Systems (CSGS) EVP receives 8,468 time-based restricted shares

Rhea-AI Filing Summary

CSG Systems International executive Elizabeth A. Bauer reported an equity award of 8,468 shares of common stock on January 20, 2026. The shares are time-based restricted stock that will vest on March 10, 2027, meaning she must satisfy continued service conditions before they fully become hers. The award was reported at a price of $0 per share, consistent with a stock grant rather than an open-market purchase.

After this grant, Bauer beneficially owned 101,859 shares of CSG Systems International common stock in direct ownership. She serves as Executive Vice President and Chief Experience Officer, so the filing reflects part of her equity-based compensation as a senior officer.
