Questar Net Income Grows 14% in 2007

February 12, 2008
Repost This

Questar Corp. (NYSE:STR) — a natural gas-focused energy company — grew net income 14% in 2007 to $507.4 million, or $2.88 per diluted share, compared to $444.1 million, or $2.54 per diluted share, for the prior year. The increase was the result of record net income by all four Market Resources subsidiaries. The 2006 result included a $15.8 million, or $0.09 per diluted share, net after-tax gain from the sale of assets.

In the fourth quarter of 2007, Questar net income was $130.8 million, or $0.74 per diluted share, compared to $121.5 million, or $0.69 per diluted share, for the 2006 period, an 8% increase.

“Questar posted double-digit net income growth for the fifth-straight year in 2007,” said Keith Rattie, Questar chairman, president and CEO. “Questar E&P grew natural gas and oil-equivalent production 8% compared to 2006 — and 15% if you add back the unhedged production we intentionally shut in due to low Rockies prices. Also, in 2007 we increased investment in our second E&P business, Wexpro, and in Gas Management, our Rockies-focused gathering and processing business. Both businesses factor big in our five-year plan — and both delivered in 2007,” Rattie added.

2007 Highlights

Questar E&P natural gas, oil and natural gas liquids (NGL) production totaled 140.2 billion cubic feet of natural gas equivalents (Bcfe), compared to 129.6 Bcfe in 2006. Natural gas comprised 87% of reported volumes. During 2007 the company shut in approximately 10.3 Bcfe (net) of unhedged natural gas and associated liquid hydrocarbon production in response to low regional market prices for natural gas in the Rocky Mountain producing region.

Questar E&P replaced 268% of 2007 production and grew proved reserves 14% to 1,868 Bcfe at year-end 2007.

Realized natural gas prices at Questar E&P increased $0.46 per thousand cubic feet (Mcf), or 8%, while realized crude oil and NGL prices increased $4.87 per barrel (bbl), or 10%. Natural gas hedges increased reported revenues by $245.7 million, while oil hedges reduced revenues by $17.2 million.

Net mark-to-market gains on natural gas basis-only swaps increased pre-tax income $5.7 million, compared to a $1.9 million reduction in 2006.

Wexpro investment base grew 15% to $300.4 million at December 31, 2007. Wexpro produced 34.9 Bcf of cost-of-service gas for delivery to affiliate Questar Gas compared to 38.8 Bcf a year ago. Questar Gas curtailed and deferred Wexpro production and purchased replacement gas at low regional prices.

Gas Management net income growth was driven by a 31% increase in third-party gathering volumes which helped boost gathering revenues 19% to $93.9 million in 2007 compared to $78.6 million a year earlier. Fee-based processing volumes increased 5% while net processing revenues increased 31% to $64.8 million due to increased volumes and a higher frac spread.

Energy Trading net income rose 117% to $20.8 million, driven primarily by increased trading and storage margins related to increased volatility in Rockies natural gas markets. Gross marketing margin totaled $31.6 million compared to $16.0 million in 2006.

Questar Pipeline earned $45.0 million, down 1% from 2006. Increased transportation revenues were offset by higher associated operating expenses. Questar Pipeline completed two significant system expansions late in 2007 — the Overthrust expansion from Kanda to Wamsutter, Wyoming, and an expansion of its southern system that provides additional capacity out of the Piceance and Uinta basins to Kern River Pipeline.

Questar Gas net income increased 1% to $37.4 million from a year ago, primarily due to new-customer growth and increased transportation services. Questar Gas earned its allowed 11.2% return on equity for the third-straight year.

Questar earned a 15.8% return on assets (ROA — defined as earnings before interest and income taxes divided by average total assets). Market Resources ROA was 19.8%, Questar Pipeline ROA was 9.4%, and Questar Gas ROA was 7.5%.

Questar Raises 2008 EPS Guidance and Production Estimate

Excluding the effects of the pending Louisiana acquisitions discussed below, Questar expects 2008 earnings to range from $2.90 to $3.05 per diluted share, compared to previous guidance of $2.85 to $3.00 per diluted share. The company expects Questar E&P 2008 production to range from 148 to 151 Bcfe. The lower end of the guidance range assumes an average NYMEX price of $7.50 per million Btu (MMBtu) for currently unhedged 2008 natural gas production and an average prompt-month NYMEX oil price of $85.00 per barrel applied to unhedged volumes. The upper end assumes an average NYMEX gas price of $8.50 per MMBtu and an average prompt-month NYMEX oil price of $90.00 per barrel applied to unhedged 2008 production. On January 31, 2008, Questar E&P announced that it had reached definitive agreement to acquire natural gas-producing properties near its core Elm Grove play in northwest Louisiana from two separate groups of sellers. The company expects to close these acquisitions by the end of February 2008 and will update net income and production guidance for the acquisitions at that time. The company’s guidance also excludes one-time items and assumes hedges in place on the date of this release, and other assumptions summarized in the table below:

Questar E&P has hedged about 75% of forecast natural gas and oil-equivalent production for 2008 with fixed-price swaps. Additionally, the company has hedged about 5% of 2008 production with natural gas basis-only swaps (see table at the end of this release).

The company estimates that a $1.00 per MMBtu change in the average NYMEX price of natural gas for 2008 would result in about a $0.04 change in earnings per diluted share.

A $10.00 per barrel change in the average NYMEX price of oil for 2008 would result in about a $0.05 change in earnings per diluted share.

Questar E&P Net Income Increases 12% in 2007

Questar E&P — a Market Resources subsidiary that acquires, explores for, develops and produces natural gas and oil — reported production of 140.2 Bcfe in 2007 compared to 129.6 Bcfe in the prior year, an 8% increase. During 2007, the company shut in approximately 10.3 Bcfe (net) of unhedged Rockies natural gas and associated liquid hydrocarbon production in response to low regional market prices for natural gas. Shut-in volumes totaled 1.2 Bcfe (net) in 2006. Low regional market prices result from insufficient takeaway capacity on interstate pipelines that transport natural gas from Rockies producing basins to markets outside the region. The December 2007 start-up of the western segment of the Rockies Express Pipeline has partially alleviated Rockies natural gas takeaway capacity constraints.

Higher realized natural gas, crude oil and NGL prices more than offset a 13% increase in average production costs. Net mark-to-market gains (losses) on natural gas basis-only swaps increased net income $3.6 million in 2007 and reduced net income $1.2 million in 2006. In 2006, Questar E&P recognized a $15.8 million net after-tax gain from the sale of assets. Exploration and abandonment expense totaled $32.8 million in 2007, compared to $42.0 million in 2006.

In the fourth quarter of 2007, Questar E&P net income rose 6% to $65.2 million compared to $61.3 million a year earlier, driven by an 11% increase in production, and higher realized natural gas, crude oil and NGL prices, partially offset by higher exploration and abandonment expense. Exploration and abandonment expense totaled $19.7 million for the current quarter compared to $6.3 million in the fourth quarter of 2006. The mark-to-market of natural gas basis-only swaps decreased net income $5.3 million in the fourth quarter of 2007 compared to a $5.5 million increase in the 2006 period.

Questar may hedge up to 100% of forecast production from proved reserves to lock in acceptable returns on invested capital and to protect cash flow and net income from a decline in commodity prices. The company uses natural gas basis-only swaps to protect cash flows and net income from widening natural gas-price basis differentials that may result from capacity constraints on regional gas pipelines.

Questar E&P production costs (the sum of depreciation, depletion and amortization expense, lease operating expense, general and administrative expense, allocated interest expense, and production taxes) per unit of gas-equivalent production increased 13% in 2007 compared to 2006.

Production volume-weighted average depreciation, depletion and amortization rates increased in both comparative periods due to higher costs for drilling, completion and related services, increased cost of steel casing, other tubulars and wellhead equipment, the ongoing depletion of older lower-cost reserves and increasing production from higher-cost fields such as Elm Grove in the Midcontinent and Vermillion Basin in the Rockies.

Lease operating expense per Mcfe increased in both comparative periods due to increased costs of materials and consumables, increased produced-water disposal costs and increased well-workover activity.

General and administrative expense per Mcfe increased due to higher labor and legal expenses in 2007.

Allocated interest expense per unit of production decreased in 2007 due to reduced debt expense in the 12-month period and increased current-year production in both periods.

Production taxes were lower in the full-year 2007 period due to lower market prices for natural gas, and were higher in the fourth quarter of 2007 due to increased market prices for crude oil and NGL compared to the year-earlier quarter. The company pays production taxes based on sales prices before the impact of hedges.

Wexpro Net Income Up 18% in 2007

Wexpro — a Market Resources subsidiary that develops and produces cost-of-service reserves for delivery to affiliate Questar Gas — reported net income of $59.2 million in 2007, up 18% from 2006. For the fourth quarter of 2007, Wexpro net income was $15.8 million, compared to $13.9 million in the prior-year period, a 14% increase. Wexpro 2007 results benefited from a higher average investment base compared to the prior-year period. Under a long-standing agreement with the states of Utah and Wyoming, Wexpro recovers its costs and earns an unlevered after-tax return of about 19 to 20% on its investment base — the investment in commercial wells and related facilities, adjusted for working capital and reduced for deferred income taxes and accumulated depreciation. Wexpro investment base at December 31, 2007, was $300.4 million compared to $260.6 million a year ago, a 15% increase.

Gas Management Net Income Up 30% in 2007

Questar Gas Management (Gas Management) — Market Resources gas-gathering and processing-services business — posted higher net income driven by higher gathering and processing margins in the fourth quarter and full year 2007. Third-party gas-gathering throughput grew 31% or 38.0 million MMBtu in 2007 compared to 2006. Fee-based gas-processing volumes were 126.6 million MMBtu in 2007, a 5% increase compared to 2006. Fee-based gas-processing revenues increased 14% or $2.2 million, while gross margin from keep-whole processing increased 40% or $12.9 million in 2007. Approximately 74% of Gas Management net operating revenue (total revenue less processing plant-shrink) was derived from fee-based contracts in 2007 compared to 77% in the 2006 period. In the fourth quarter of 2007, Gas Management net income increased 26% to $14.7 million compared to $11.7 million in the 2006 period, driven by higher gathering and processing margins.

Questar Pipeline Net Income Down 1% in 2007

Questar Pipeline — a subsidiary that provides interstate natural gas transportation and storage services — reported slightly lower 2007 net income as increased demand revenues from new transportation contracts and higher liquids-processing revenues were offset by higher operating costs. Operating, maintenance, general and administrative expenses increased 18% due to new operating costs from system-expansion projects and processing services. Questar Pipeline began collecting revenues from an Overthrust Pipeline Opal expansion in 2006 at an interim delivery point on the Kern River pipeline prior to completion of new permanent facilities in January 2007. Questar Pipeline incurred higher operating and depreciation expense associated with these facilities in 2007. Questar Pipeline net income was $11.8 million in the fourth quarter of 2007, up 2% from $11.6 million earned in the year-ago period, driven by increased transportation revenues from a system expansion.

Questar Gas Net Income Up 1% in 2007

Questar Gas — which provides retail natural gas distribution services in Utah, Wyoming and Idaho — reported higher net income driven by customer growth and higher transportation revenues in 2007. Operating, maintenance, general and administrative expenses totaled $136 per customer in 2007 compared to $135 in 2006. Questar Gas net income was $17.9 million in the fourth quarter of 2007, compared to $17.5 million in the year-earlier period. At December 31, 2007, Questar Gas served 874,000 customers, up 23,000 or 3% from December 31, 2006.
