The station is owned by Cumulus Media and broadcasts an adult contemporary music format.

The station at 93.7 FM first signed on in 1993 as WMGB, broadcasting a contemporary hit radio (CHR) format known as "B93.7".

On September 10, 2001, WMGB exchanged frequencies with WEGF, an adult contemporary (AC) station at 95.1 FM.

A week later, on September 19, WEGF changed its call sign to WPEZ to match its new moniker.

From 2009 to 2019, Brian Roberts was WPEZ's program director and hosted the Z93.7 More Music Morning Show.
