A pipeline company will be required to pay another $410 million for conditions not being met when breaking off a merger, Delaware Court of Chancery Vice Chancellor Sam Glasscock III decided Wednesday.

The opinion follows Glasscock’s finding that Texas-based Energy Transfer LP, which owns and operates pipelines for natural gas, crude oil and related products, was entitled to back out of the deal with The Williams Companies Inc., an Oklahoma-based natural gas infrastructure owner and operator.
