The PNC Financial Services Group has executed several monumental corporate combinations throughout its history to scale its national footprint. Its most significant and transformative merger was completed with National City Corporation, a massive multi-billion-dollar transaction during the 2008 financial crisis that dramatically expanded PNC's retail and commercial branch network across key Midwestern and industrial states. Additionally, PNC expanded its footprint significantly by merging operations with BBVA USA Bancshares, absorbing its extensive Sunbelt branch network, and more recently integrating FirstBank Holding Company to anchor its western regional presence.
