Ashland ( ASH) said fiscal fourth-quarter revenue rose slightly from a year ago, but the company said disruptions from the recent hurricanes and escalating energy prices put pressure on its chemicals and transportation construction segments. Revenue for the quarter ended Sept. 30 rose to $2.55 billion from $2.50 billion last year. Net income during the fourth quarter was $93 million, or $1.24 a share, compared with $200 million, or $2.76 a share, last year. The prior-year quarter included operating income of $146 million from Ashland's 38% interest in Marathon Ashland Petroleum, its maleic anhydride business and 60 Valvoline Instant Oil Change units that were transferred to Marathon Oil ( MRO) this past June. Shares of Ashland, based in Covington, Ky., closed Friday at $52.58.
