The retailer’s SRS subsidiary will initiate a cash tender offer to acquire all GMS common stock for $110 per share.

Home Depot's push into the pro market began in earnest last year, when the company dropped $18.5 billion to buy SRS Distribution.

Home Depot said on Monday unit SRS Distribution has agreed to acquire specialty building products distributor GMS for about $4.3 billion, stepping up its efforts to capture more demand from professional contractors.
