NEW YORK (Bloomberg) -- Activist investor Lion Point Capital has built a position in Carrizo Oil & Gas Inc. and wants the driller to explore a sale or merger with another Permian explorer to gain scale.

The New York-based hedge fund has an economic exposure to about 6% of Carrizo and believes the company is undervalued, according to a filing Monday. Lion Point, which was founded by a former Elliott Management Corp. executive, has held discussions with management about its views.

Among the potential companies Lion Point would like Carrizo to explore a merger with is fellow Permian driller PDC Energy Inc., in which the hedge fund also holds a stake, according to people familiar with the matter who asked not to be identified as the details aren’t public. In addition to giving the company scale in the coveted basin, a merger or takeover would improve Carrizo’s cash flows and cost structure, and allow it to reduce leverage.

Shares of Houston-based Carrizo have fallen by about 43% over the past 12 months to close Friday at $11.50 apiece, giving it a market value of about $1.1 billion. They were little changed at 9:34 a.m. in New York Monday.

Representatives for Carrizo and PDC weren’t immediately available for comment.

Carrizo has held early stage discussions about tie-up with U.S. energy explorer SM Energy Co., people familiar with the matter said in March. There’s no certainty the deliberations will lead to a transaction, they said at the time.

There’s been mounting speculation about deals in the Permian basin in the U.S. Southwest in recent months as oil and gas producers in the region seek scale. The activity has been capped by the ongoing heavyweight battle between Occidental Petroleum Corp.

and Chevron Corp. to take over Anadarko Petroleum Corp. Lion Point has a history of agitating for companies in the oil and gas sector to sell themselves. Last year, the hedge fund was among investors who urged Resolute Energy Corp. to sell itself. Resolute agreed to be acquired by Cimarex Energy Co. in November in a deal valued at about $828 million at the time.

Didric Cederholm, a former portfolio manager at Elliott, and Jim Freeman, a former senior analyst at Perry Capital, formed Lion Point in 2015.
