SEMCO Publishing, Owner of Rock Products, Acquires Aggregates Manager


Denver-based SEMCO Publishing, owner of Rock Products, Cement Americas, Concrete Products and The Asia Miner magazines, has acquired Aggregates Manager and all its related products from Randall-Reilly, Tuscaloosa, Ala.

The magazine will be merged into Rock Products beginning with the January 2020 issue, while Aggregates Manager's popular "Aggregates Atlas" will continue to be published annually by SEMCO.

Aggregates Manager editor-in-chief Therese Dunphy will bring her 20-plus years of industry experience to the Rock Products team as a monthly contributor and producer of the "Aggregates Atlas."

"This is a great opportunity for SEMCO Publishing to expand the Rock Products brand and enhance its presence in the marketplace," said Peter Johnson, president of SEMCO. “Randall-Reilly has long been at the forefront of information and data services and the combined resources of Rock Products and Aggregates Manager will give us the largest circulation and broadest audience reach of any publication in the aggregates industry. Rock Products is the aggregates industry's leading publication, and this acquisition, coming as the magazine begins its 125th year of service to the industry, bolsters our commitment to aggregates producers and the advertising base that has supported us for many years."

SEMCO Publishing continues to expand its publishing portfolio in the heavy materials industries and is launching North American Mining Products in time for the 2020 MINExpo Exhibition in Las Vegas.

“We are excited to have found a home for such a long-standing brand and are pleased that the Atlas will continue to be available as a critical resource to the aggregates industry,” said Brent Reilly, Randall-Reilly CEO. “Randall-Reilly will continue to focus on our higher-growth, data-driven businesses in construction, trucking and industrial markets.”
