This year witnessed a 13.2% increase from 2011, while surpassing $2 billion in total revenue for the first time. Net income fell to $335.6 million from $389.4 million, however, owing to startup and infrastructure costs at operations in Pennsylvania, West Virginia and Western Kentucky.

Alliance CEO Joseph Craft III hailed the performance as “truly remarkable considering the challenges in 2012,” pointing to low natural gas prices, a mild winter and fast-evolving Environmental Protection Agency regulations targeting the sector.
