A former Findlay company is getting bought out in a multibillion-dollar deal. ConocoPhillips is buying Marathon Oil in a deal valued at $22.5 billion, which includes $5.4 billion in debt. Marathon Oil is based out of Houston, Texas, and split off from Marathon Petroleum in Findlay in 2011, making them two separate companies. Marathon Oil deals with oil exploration and production, while Marathon Petroleum refines, markets, and transports petroleum products for consumers.
