Electric sales margin increased $0.1 million in the three month period ended September 30, 2008 compared to
the same period in 2007, reflecting higher electric base rates partially offset by lower sales volumes. For the nine month period ended September 30, 2008, electric sales margin decreased $0.3 million compared to the same period in 2007. The
decrease in electric sales margin in the nine month period primarily reflects lower sales volumes, partially offset by higher electric base rates, implemented in March of 2008. Total electric kilowatt-hour (kWh) sales decreased 2.0% and 2.1% in the
three and nine month periods ended September 30, 2008, respectively, compared to the same periods in 2007, driven by lower average usage per customer reflecting milder summer temperatures, a slowing economy and energy conservation.

Gas sales margin increased $0.2 million and $1.3 million in the three and nine months ended September 30, 2008, respectively, compared to the same periods in
2007. The increase in the three month period reflects higher gas base rates implemented in November 2007 and higher natural gas sales to Commercial and Industrial customers. The increased sales margin in the nine month period reflects higher rates,

partially offset by lower sales. Natural gas sales in the three month period ended September 30, 2008 increased 5.7% compared to the same period in
2007. For the nine month period ended September 30, 2008, natural gas sales decreased 0.5% compared to the same period in 2007, reflecting a milder winter heating season earlier this year and lower average usage per customer.

Operation & Maintenance (O&M) expenses increased $0.5 million for the three month period ended
September 30, 2008 compared to the same period in 2007. The increase in the three month period reflects higher salary and benefit costs of $0.3 million, higher bad debt expenses of $0.2 million and higher utility operating costs of $0.2
million, partially offset by lower professional fees of $0.2 million. For the nine month period ended September 30, 2008, O&M expenses decreased $1.1 million compared to the same period in 2007, including a reduction of $2.8 million from
the proceeds of an insurance settlement, lower utility operating costs of $0.1 million and lower professional fees of $0.1 million, partially offset by increases in salary and benefit costs of $1.5 million and higher bad debt expenses of $0.4
million.

Depreciation, Amortization & Other expenses decreased $0.1 million in the three month period ended September 30, 2008, reflecting
lower amortization of information systems related costs and lower income tax expense in the current quarter compared to the same period in 2007, partially offset by higher depreciation on normal utility plant additions. For the nine month period
ended September 30, 2008, Depreciation, Amortization & Other expenses increased $1.2 million, primarily reflecting the amortization, in the first quarter of 2008, of $0.7 million of natural gas inventory carrying costs deferred under a
previous regulatory ruling and higher depreciation on normal utility plant additions.

Interest Expense, Net increased $0.1 million and $0.5 million for
the three and nine month periods ended September 30, 2008 compared to the same periods in 2007, reflecting higher overall debt outstanding.

Also in
the third quarter, the Unitil Corporation Board of Directors declared the regular quarterly dividend on the Companys common stock of $0.345 per share. This quarterly dividend results in a current effective annual dividend rate of $1.38 per
share representing an unbroken record of quarterly dividend payments since trading began in Unitils common stock.
