The accuracy of such statements is subject to a number of risks, uncertainties and assumptions including, but not limited to, the following factors: (1) the risk that the conditions to the closing of the SJW Group transaction are not satisfied, including the risk that required approval from the shareholders of Connecticut Water for the transaction is not obtained; (2) the risk that the regulatory approvals required for the transaction are not obtained, on the terms expected or on the anticipated schedule; (3) the effect of water, utility, environmental and other governmental policies and regulations; (4) litigation relating to the transaction; (5) the ability of the parties to the transaction to meet expectations regarding the timing, completion and accounting and tax treatments of the proposed transaction; (6) the occurrence of any event, change or other circumstance that could give rise to the termination of the transaction agreement between the parties to the proposed transaction; (7) changes in demand for water and other products and services of Connecticut Water; (8) unanticipated weather conditions; (9) catastrophic events such as fires, earthquakes, explosions, floods, ice storms, tornadoes, terrorist acts, physical attacks, cyber-attacks, or other similar occurrences that could adversely affect Connecticut Water’s facilities, operations, financial condition, results of operations, and reputation; (10) risks that the proposed transaction disrupts the current plans and operations of Connecticut Water; (11) potential difficulties in employee retention as a result of the proposed transaction; (12) unexpected costs, charges or expenses resulting from the transaction; (13) the effect of the announcement or pendency of the proposed transaction on Connecticut Water’s business relationships, operating results, and business generally, including, without limitation, competitive responses to the proposed transaction; (14) risks related to diverting management’s attention from ongoing business operations of Connecticut Water; (15) the trading price of Connecticut Water’s common stock; and (16) legislative and economic developments.

In addition, actual results are subject to other risks and uncertainties that relate more broadly to Connecticut Water’s overall business and financial condition, including those more fully described in Connecticut Water’s filings with the U.S. Securities and Exchange Commission (the “SEC”), including, without limitation, its annual report on Form 10-K for the fiscal year ended December 31, 2017 and its quarterly report on Form 10-Q for the period ended September 30, 2018. Forward-looking statements are not guarantees of performance, and speak only as of the date made, and neither Connecticut Water nor its management undertakes any obligation to update or revise any forward-looking statements except as required by law.
