Warrick Rolling Mill Acquisition. On March 31, 2021, we acquired Alcoa Warrick LLC and certain assets comprising the aluminum casting and rolling mill facility located in Warrick County, Indiana (collectively, “Warrick”) for a purchase price of $670.0 million. Warrick is a leading producer of can stock for the beverage and food packaging industry in North America. The transaction provides us with non-cyclical end market diversification and re-entry into the packaging end market. Acquisition-related costs incurred and expensed during the quarter and six months ended June 30, 2021 were $3.0 million and $14.0 million, respectively, primarily related to legal and consulting fees and included within Selling, general, administrative, research and development (“SG&A and R&D”).

The preliminary purchase consideration to allocate was determined as follows (in millions of dollars):

The preliminary purchase consideration to allocate is subject to customary post-closing adjustments, estimates of which are included in the table above. We prepared an initial allocation of the purchase consideration as of the acquisition date based on our understanding of the fair value of the acquired assets and assumed liabilities. As we continue to obtain additional information supporting the final valuation of inventories, property, plant and equipment, intangible assets, other assets and long-term liabilities, we will refine the estimates of fair value and may revise our allocation of the purchase consideration. We expect to finalize the valuation of the assets and liabilities, as well as the post-closing adjustments as soon as practicable, but in any event no later than one year from the acquisition date.

The following table summarizes the preliminary fair values of assets acquired and liabilities assumed as of the acquisition date as well as adjustments made up to June 30, 2021 (in millions of dollars):

The Warrick rolling mill has historically purchased aluminum and electrical power from Alcoa’s smelter and power plant in Warrick County, Indiana. Alcoa’s Warrick smelter historically sold the aluminum to the Warrick rolling mill at smelter cost and electrical power from Alcoa’s power plant at negotiated prices between the parties.

As part of the acquisition of Warrick, we negotiated pricing for aluminum and electrical power with Alcoa at alternative rates which more closely align with market pricing. The table above does not reflect the cost of aluminum and electrical power under these negotiated rates.
