Price, Consensus and EPS Surprise Koppers Holdings Inc. price-consensus-eps-surprise-chart | Koppers Holdings Inc. QuoteSegment HighlightsRevenues from the Railroad and Utility Products and Services (RUPS) segment surged around 40% year over year to $185 million. The growth was driven by acquisitions and higher volumes in the commercial crosstie market that more than offset lower Class I treating volumes.The Performance Chemicals (PC) unit recorded sales of $108.2 million in the quarter, down around 1% year over year. The decline reflects the continued trend of customers delaying or reducing wood-treating activities due to volatility in lumber prices. Revenues from the Carbon Materials and Chemicals (CMC) division rose around 4% to $149.5 million, driven by higher sales prices for carbon pitch in North America, Europe and Australia that more than offset reduced volumes of soft pitch in China and phthalic anhydride in North America.FinancialsKoppers ended the quarter with cash and cash equivalents of $62.5 million, up around 25% year over year.
