Walter Energy is the subject of a class action lawsuit, which was filed earlier this week on behalf of the impacted purchasers of Walter common stock.

Officials confirmed the meeting and voting would include shareholders of record as of the close of business on February 28.

Several law firms, including Pennsylvania-based Howard Smith, New York group Harwood Feffer and Rigrodsky and Long of Delaware, are seeking remedies under the Securities Exchange Act of 1934 and have filed the lawsuit at the US District Court for the Northern District of Alabama.

The class action group includes those who purchased stock between April 20 and September 21, 2011.

Their complaint alleges the defendant, Walter, was experiencing “squeeze” events in Alabama and lower coal transportation rates in Canada that significantly reduced its coal production.

It alleges Walter was experiencing a significant decline in its margins and profitability and the defendants lacked a reasonable basis for its positive statements about the company and its business prospects during the class period.

The AGM will take place on April 19 at the Wynfrey Hotel in Birmingham, near the company’s headquarters at Riverchase Galleria.
