NEWS RELEASE May 1, 2003 FOR RELEASE AT 6:00 A.M. EDT THURSDAY, MAY 1, 2003 NWN REPORTS RESULTS FOR QUARTER ENDED 3/31/03 PORTLAND, Ore. - Northwest Natural Gas Company (NYSE: NWN), dba NW Natural, reported consolidated earnings applicable to common stock of $26.3 million, equivalent to $1.01 a diluted share, for the three months ended March 31, 2003, Mark S. Dodson, president and chief executive officer, said Thursday. These results compare to earnings of $33.9 million, or $1.32 a diluted share, in the first quarter of 2002. "We faced some challenges in the first quarter due to the impact of much warmer than average weather and a weak economy," Dodson said, "but we were able to mitigate these effects through the advantageous use of our gas supply portfolio and continuing growth in earnings from our gas storage operations." First Quarter Detail - -------------------- Total gas deliveries in the first quarter were 347 million therms, down 12 percent from the first quarter of 2002. Operating margin (gross revenues minus cost of sales) was $98.6 million, down $12.1 million or 11 percent from last year. The lower sales and operating margin in the first quarter of 2003 were primarily due to the effects of warmer weather in the Company's temperature-sensitive market segments. Weather in NW Natural's service area in Oregon and Washington was 8 percent warmer than the 20-year average for the period and 12 percent warmer than last year's first quarter. Sales to residential and commercial customers were 220 million therms, down 10 percent from last year. The Company estimates that the warmer weather and related factors in the first quarter reduced sales to these customers from last year's levels by about 32 million therms and margin by about $11.7 million, equivalent to 28 cents a share. Sales and transportation deliveries to industrial customers in the first quarter were 126 million therms, down 14 percent from the first quarter of 2002. Margin from the industrial market was down 21 percent. The decline in deliveries was due to a combination of warmer weather and the weaker economy, while the greater percentage decline in margin was due to shifts by some customers during 2002 from higher-margin sales or transportation schedules to lower-margin transportation schedules. NW Natural has a Purchased Gas Adjustment (PGA) tariff in Oregon under which it absorbs 33 percent of any excess cost of gas, or retains 33 percent of any savings, both as compared to the gas commodity prices built into rates. NW Natural's gas costs in the first quarter of 2003 were slightly lower than the gas costs embedded in rates, despite rising gas prices in the spot market, with the effect that NW Natural's share of the savings increased margin by $0.6 million, equivalent to about 1 cent a share of earnings. Last year, NW Natural's gas costs in the first quarter were much lower than the projected costs built into rates, and the Company's share of the savings realized from its gas purchases during the quarter contributed $8.7 million of margin, equivalent to 21 cents a share of earnings. Due to the warm weather and the reduced gas requirements of its industrial sales customers during the first quarter, NW Natural was able to use gas supplies that were under contract for the winter season, but were not required for delivery to core market customers, to make sales in the off-system market. The purchase prices for this gas had been locked-in through commodity swap and call option agreements entered into last year at levels much lower than current market prices, so the gas could be sold in the interstate market at a gain. Under the PGA tariff, the margin from these sales is treated as a reduction to the cost of gas, with the effect that 67 percent is deferred for refund to NW Natural's customers and the remaining 33 percent is retained by the Company. NW Natural's share of the margin from off-system gas sales in the first quarter of 2003 was $4.0 million, equivalent to 9 cents a share of earnings, compared to $0.2 million or less than 1 cent a share in the first quarter of 2002. NW Natural earned $1.3 million, after tax and revenue sharing, from interstate gas storage services in the first quarter of 2003. These earnings were equivalent to 5 cents a share, compared to earnings from storage services of 3 cents a share in the first quarter of 2002. The Company provides gas storage services to customers in the interstate market from its Mist gas storage field, using storage capacity that has been developed in advance of core utility customers' requirements. Results for the first quarter of 2003 include negligible margin from the electric generation market, compared to $2.3 million of margin from this market in the first quarter of 2002. The difference is equivalent to an earnings reduction of about 5 cents a share. One-year contracts for service to two customers in this market went into effect in the second half of 2001. The customers did not extend the contracts beyond their expiration dates on June 30, 2002; spot market electricity prices by then had gone down and wholesale power supplies were more readily available. Despite the current weakness in the regional economy, NW Natural continues to be one of the fastest growing gas distribution utilities in the country. The 19,086 customers added to the Company's system since March 31, 2002, represent a growth rate of 3.5 percent. Customer growth in the past year contributed an estimated 7 million therms in sales volumes and $2.7 million in margin to the first quarter's results. Updated Outlook for 2003 - ------------------------ NW Natural estimates that its earnings for the quarter ending June 30, 2003, will be in the range of 5 to 15 cents a share, and now estimates that its earnings for 2003 will be in the range of $1.65 to $1.80 a share. Consistent with prior earnings guidance, both estimates assume average weather conditions for the balance of the year. The earnings estimate for 2003 also assumes results in NW Natural's general rate case in Oregon that are consistent with the revenue requirement requested in its filing. NW Natural filed its general rate case in November 2002, proposing a revenue increase of $38 million per year from Oregon operations through rate increases averaging 6.8 percent. The filing is subject to approval by the Oregon Public Utility Commission (OPUC), which is expected to authorize new rates to be in effect during the fourth quarter of 2003. The filing includes a proposal for a weather normalization mechanism that would reduce the Company's financial exposure if weather is significantly warmer than average, as well as its customers' exposure to high gas bills if weather is significantly colder than average. Weather normalization rate treatment, if approved by the OPUC for NW Natural, would be applied on a prospective basis. Dividends Declared - ------------------ The Board of Directors of NW Natural has declared a quarterly dividend of 31.5 cents a share on the Company's common stock, as well as regular quarterly dividends on its preferred stock. The dividends will be paid on May 15, 2003, to shareholders of record on April 30, 2003. NW Natural serves about 566,000 customers in Oregon and southwest Washington.
