Pennichuck Corporation Announces Higher Second Quarter Earnings

MERRIMACK, NH (August 5, 2010) – Pennichuck Corporation (NASDAQ: PNNW) today announced that net income for its second quarter ended June 30, 2010 was $996,000, or $0.21 per share (diluted), on revenues of $9.1 million. Excluding non-operating eminent domain-related costs which totaled $134,000, second quarter earnings would have been $0.23 per share (diluted). This compares to earnings for the second quarter in 2009 of $763,000, or $0.18 per share (diluted), on revenues of $8.5 million. Excluding eminent domain-related costs which totaled $70,000, 2009 second quarter earnings would have been $0.19 per share (diluted).

The increase in second quarter earnings was due principally to increased water utility revenues of $841,000 offset in part by higher utility operating expenses of $419,000 and increased income tax expense of $152,000.

The increase in utility revenues for the quarter resulted from higher water rates prospectively granted by the New Hampshire Public Utilities Commission (“NHPUC”) to the Company’s Pennichuck Water Works, Inc. utility subsidiary (“PWW”) in August 2009 and increased water usage volumes due to dryer and warmer weather conditions toward the end of the quarter as compared to the same period in 2009. The increase in utility operating expenses for the quarter was due principally to higher real estate taxes including state utility taxes, increased production costs, and increased general and administrative expenses.

Net income for the six months ended June 30, 2010 was $1.1 million, or $0.23 per share (diluted), on revenues of $16.5 million. Excluding non-operating eminent domain-related costs which totaled $233,000, earnings for the six months ended June 30, 2010 would have been $0.26 per share (diluted). This compares to earnings for the six months ended June 30, 2009 of $695,000, or $0.16 per share (diluted), on revenues of $15.5 million. Excluding eminent domain-related costs which totaled $188,000, earnings for the six months ended June 30, 2009 would have been $0.19 per share (diluted).

The increase in earnings for the six months was due principally to increased water utility revenues of $1.3 million and a decrease in interest expense of $148,000, offset in part by higher utility operating expenses of $602,000, lower Allowance for Funds Used During Construction (“AFUDC”) of $131,000, lower water management service operating income of $100,000, higher eminent domain expenses of $45,000 and increased income tax expense of $246,000.

The increase in utility revenues for the six month period resulted from higher water rates prospectively granted by the NHPUC to PWW in August 2009 and increased water usage volumes due to dryer and warmer weather conditions toward the end of the period as compared to the same period in 2009. The increase in utility operating expenses for the six months was due principally to increased production costs, higher real estate taxes including state utility taxes, and increased general and administrative expense.
