The impact of acquisition announcements on the acquiring company's stock can be mixed. While it could lead to a short-term rise due to potential synergies and growth prospects, it could also lead to a drop due to the costs associated with the acquisition. In this case, it's uncertain how GXO Logistics' stock will react in the short term.

Acquisition announcements often lead to a rise in the share price of the company being acquired, as it is usually bought at a premium. This is the case with PFSweb, whose shares have risen following the announcement of its acquisition by GXO Logistics.
