In the three months ended March 31, 2011, the income trust’s cash flow per share jumped 55.6%, to $0.84 from $0.54. Revenue rose 33.8%, to $169.6 million from $126.8 million. This was mostly due to a recovering economy and higher prices for sulphuric acid. Chemtrade recently announced that it will buy Marsulex Inc. for $419.5 million. Marsulex provides environmental services that include controlling air quality and treating and handling industrial by-products and hazardous waste. The company also makes and sells chemicals. Adding Marsulex should build on the income trust’s existing strengths. Moreover, Chemtrade is already very familiar with Marsulex. That lowers the risk of unpleasant surprises. The company expects Marsulex to immediately begin adding to its cash flow per unit, even without accounting for savings from eliminating overlapping functions. The income trust’s distribution is $0.10 a month, which yields a high 8.3% on an annualized basis.
