Freeport-McMoRan response to Icahn’s investment

Icahn is now the largest shareholder of Freeport-McMoran. In response to his investment, the company said it “maintains an open dialogue with our shareholders and welcomes constructive input toward our common goal of enhancing shareholder value.”

Freeport-McMoRan announced its decision to reduce its capital expenditures, production levels, operating, administrative and exploration costs in response to the declining commodity prices.

The company said its 2016 capital expenditure budget is expected to decline to $4 billion from $6.3 billion this year.

Freeport-McMoRan estimated that its mining capital expenditures will decline 25% or $700 million next year. Its copper sales are expected to drop 150 million pounds per year in 2016 and 2017. The company also estimated a 20% reduction in site production and delivery costs next year.

Richard C. Adkerson, Chairman and CEO of Freeport-McMoRan and James Flores, Vice Chairman and FM O&G CEO said, “The steps we are taking to reduce costs and capital expenditures will strengthen our financial position during a period of weak and uncertain market conditions and preserve our large resource base for improved future market conditions.”

Analysts’ reactions

Clarksons Platou Securities analysts Jeremy Sussman and Lee McMillan commented that the company’s decision to revise its capital expenditure and operating plans wasn’t a big surprise because the company already indicated last month that it would review its copper operations.

Sussman and McMillan maintained their Neutral rating on Freeport-McMoran and lowered their price target to $12 a share.

On the other hand, UBS analysts Brian MacArthur maintained his Buy rating on the stock with a price target of $19 per share.
