MasTec stock drops nearly 9% in Thursday trade as infrastructure contractors slide — what to watch next
New York, January 8, 2026, 14:55 ET — Regular session MasTec, Inc. (MTZ) shares fell about 8.9% to $214.86 in afternoon trading on Thursday, after opening near $236 and sliding to an intraday low of $213.98. The stock was last down $20.89 on the day. The move underscores how quickly sentiment can flip in U.S. infrastructure contractors, where investors have been leaning into multi-year work tied to power grids, pipelines and network upgrades. When the trade gets crowded, small shifts in risk appetite can turn into a big tape move. MasTec’s drop came alongside a broader selloff in the group.
