Regional parcel carrier LSO has announced the acquisition of Express Courier International, a same-day carrier in the southeast and mid-south region, to form what it describes as “a super-regional parcel carrier,” spanning across 13 states throughout the Southeast and Southwest.

The combination of LSO and Express creates the largest regional parcel carrier in the southern United States, according to LSO. Terms of the deal were not released.

“Our combined strength will allow us to provide our customers with unique service offerings, customized solutions, same-day, as well as regional overnight services, enhanced footprint and expanded product variety,” said Chuck Moyer, CEO of Express Courier International.

LSO and Express will provide customers with a regional service offering that includes a combination of on-demand, scheduled/routed, distribution, warehousing and day-definite guaranteed products. Using technology, the combined companies will provide a centralized monitoring system that monitors customer expectations, key performance indicators and other impact factors, according to LSO.

LSO, founded in 1991, is headquartered in Austin, Texas and offers a full range of next-day, day-definite guaranteed deliveries.

Express Courier International is headquartered in Nashville, Tennessee and operates in 13 states with a fleet of over 1,800 vehicles.
