Summit Materials announced an agreement to acquire Argos USA (US operations of Cementos Argos) for $3.2 bn, consisting of ~$1.2bn in cash (~40% of transaction value), and ~54.7mn shares of SUM stock (~60% of transaction value). According to SUM, Argos USA has installed cement clinker capacity of 6 mn tons and grinding capacity of 9.6 mn tons per annum, with nearly 80% of cement sales through vertically integrated ready mix operations. The transaction value implies $533 per ton of cement clinker capacity, compared to replacement costs of $600-700 across the industry, based on our fieldwork and comments from industry participants. The key investor debate would hinge on SUM’s ability to deliver margins on the acquired operations closer to industry standard margins.
