Unitil Reports First Quarter Earnings

05/01/2003

Hampton, NH - May 1, 2003: Unitil Corporation (AMEX: UTL) (www.unitil.com) today announced earnings per common share of $0.52 for the first quarter of 2003, an improvement of $0.16 compared to the first quarter of 2002. This improved performance is primarily attributable to strong electric and gas sales, driven by weather and system growth, and higher electric and gas prices for utility distribution services. Net income Applicable to Common Shareholders was $2.5 million for the first quarter of 2003 compared to $1.7 million in the first quarter of 2002.

"We are pleased with our improved year over year financial results", said Robert G. Schoenberger, Unitil's Chairman and Chief Executive Officer. "Increased cash flow and earnings from our New Hampshire and Massachusetts distribution operations provide solid support for our continued investments in gas and electric distribution facilities to meet growing service requirements in our relatively high-growth communities."

Total electric kilowatt-hour (kWh) sales volume increased 12% in the first quarter of 2003 due to the colder winter heating season and customer growth. Total firm therm gas sales increased 29% in the first quarter of 2003, reflecting a colder winter heating season and an increase in the number of non-residential customers. On average, heating degree-days were 30% above last winter and 10% above normal.

In total, electric revenues increased by $14.9 million in the first quarter of 2003 to $52.1 million compared to 2002 due to the increases in unit sales, new electric distribution service rates and an increase in wholesale commodity fuel prices. Gas revenues in total increased by $5.5 million over the first quarter of 2002 to $12.4 million, reflecting higher unit sales, new gas distribution service rates and increased gas commodity wholesale supply prices compared to the prior year. Both electric and gas supply costs are collected from customers through periodic cost recovery mechanisms, and therefore, changes in these costs do not affect the Company's net income.
