NEW YORK (MarketWatch) -- Schweitzer-Maudit International Inc. /zigman2/quotes/208081440/composite SWM -1.73% said Friday it expects second-quarter earnings of about 38 cents a share, less than its previous expectations. The current average estimate of analysts polled by Thomson First Call is for a profit of 54 cents a share in the June period.

Looking ahead, the company said it expects earnings of $1.40 to $1.50 a share for the full year. The stock closed Thursday at $31.59, down 2.4%.
