These forward-looking statements include statements regarding Unitil Corporation’s (“Unitil”) financial condition, results of operations, capital expenditures, business strategy, regulatory strategy, market opportunities, and other plans and objectives. In some cases, forward-looking statements can be identified by terminology such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential” or “continue”, the negative of such terms, or other comparable terminology. These forward-looking statements are neither promises nor guarantees, but involve risks and uncertainties that could cause the actual results to differ materially from those set forth in the forward-looking statements. Those risks and uncertainties include: Unitil’s regulatory environment (including regulations relating to climate change, greenhouse gas emissions and other environmental matters); fluctuations in the supply of, demand for, and the prices of energy commodities and transmission capacity and Unitil’s ability to recover energy commodity costs in its rates; customers’ preferred energy sources; severe storms and Unitil’s ability to recover storm costs in its rates; general economic conditions; variations in weather; long-term global climate change; Unitil’s ability to retain its existing customers and attract new customers; Unitil’s energy brokering customers’ performance and energy used under multi-year energy brokering contracts; increased competition; integrity and security of operational and information systems; publicity and reputational risks; and other risks detailed in Unitil's filings with the Securities and Exchange Commission, including those appearing under the caption "Risk Factors" in Unitil's Annual Report on Form 10-K for the year ended December 31, 2012. Readers should not place undue reliance on any forward looking statements, which speak only as of the date they are made. Unitil undertakes no obligation to update any forward- looking statements to reflect any change in Unitil’s expectations or in events, conditions, or circumstances on which any such statements may be based, or that may affect the likelihood that actual results will differ from those set forth in the forward-looking statements. |
