Black Hills Corp. (NYSE: BKH) today announced 2014 first quarter financial results. Net income, as adjusted, and net income were both $48 million, or $1.08 per diluted share, compared to net income, as adjusted of $38 million, or $0.87 per diluted share, and net income of $43 million, or $0.97 per diluted share, for the same period in 2013 (net income, as adjusted, is a non-GAAP measure, and an accompanying schedule for the GAAP to non-GAAP adjustment reconciliation is provided).

“We are pleased with the continued strong operational and financial performance of our businesses,” said David R. Emery, chairman, president and chief executive officer of Black Hills Corp. “Earnings of $1.08 per share reflect a 24 percent increase compared to adjusted earnings in the same period last year. Results were driven by earnings growth at our utilities, coal mining and power generation segments. Notably, our gas utilities' results were stronger than expected due to colder-than-normal weather, adding approximately $0.10 per share positive earnings impact. Interest expense declined substantially this quarter due to lower interest rates and settlement of interest rate swaps from refinancing activity in late 2013.”

“We continued to set a solid foundation for future earnings growth,” said Emery. “Construction of the $222 million Cheyenne Prairie Generating Station is on schedule and within budget. Three rate cases seeking to recover investments in the plant have been filed. We also placed two Mancos Shale horizontal wells on production during the quarter.”

Due to strong first quarter financial performance, primarily related to colder-than-normal weather, the company raised its 2014 earnings guidance range to $2.65 to $2.85 per share.

Black Hills Corp. highlights, recent regulatory filings and other updates include:

Utilities

  • On April 30, Colorado Electric filed a rate request with the Colorado Public Utilities Commission to increase its annual revenue by $8.0 million to recover increased operating expenses and infrastructure investments, including those for the Busch Ranch Wind Farm. The filing also seeks to implement a rider to recover a return on the construction costs of building a new natural gas-fired generating turbine that will replace the retired W.N. Clark power plant.
  • On April 29, Kansas Gas filed a rate request with the Kansas Corporation Commission to increase its annual revenue by $7.3 million, primarily to recover infrastructure investments made since its last rate filing in late 2006.
  • Construction for the 132 megawatt, natural gas-fired Cheyenne Prairie Generating Station in Cheyenne, Wyo., is on schedule and within budget. The new power plant is expected to begin commercial operation in October 2014. The plant will serve customers of Cheyenne Light and Black Hills Power in Wyoming and South Dakota.
  • On March 31, Black Hills Power filed a rate request with the South Dakota Public Utilities Commission to increase its annual revenue by $14.6 million to recover increased operating expenses and infrastructure investments, primarily for the Cheyenne Prairie Generating Station.
  • On March 21, Black Hills Power retired the Ben French, Neil Simpson I and Osage coal-fired power plants. These three plants, totaling 81 megawatts, were closed because of federal environmental regulations. These plants will largely be replaced by Black Hills Power's share of the Cheyenne Prairie Generating Station.
  • On Feb. 25, Colorado Electric received the final written order from the Colorado Public Utilities Commission approving a settlement agreement for the Electric Resource Plan filed by Colorado Electric on May 1, 2013. The settlement approved the construction of a 40 megawatt, natural gas-fired combustion turbine to replace W.N. Clark. The plan also included retirement of Pueblo 5 and 6 units.
  • On Jan. 17, Black Hills Power filed a request with the Wyoming Public Service Commission to increase its annual revenue by $2.8 million to recover increased operating expenses and investments made in electric infrastructure, including the Cheyenne Prairie Generating Station.
  • Our utilities continued to acquire small natural gas distribution systems adjacent to their existing service territories. A small natural gas system was purchased during the first quarter, adding approximately 70 new customers in Kansas. An acquisition was announced in January that will add 400 customers in northeastern Wyoming.
  • On Dec. 2, 2013, Cheyenne Light, Fuel & Power filed requests with the Wyoming Public Service Commission to increase its annual revenue by $14.1 million to recover increased operating expenses and investments in electric and natural gas infrastructure, including the Cheyenne Prairie Generating Station.

Non-regulated Energy

  • Two southern Piceance Basin horizontal wells, drilled and completed in the Mancos Shale formation in 2013, were placed on production during the first quarter.

Corporate

  • On April 28, Black Hills’ board of directors declared a quarterly dividend on the common stock. Shareholders of record at the close of business on May 16 will receive $0.39 per share, equivalent to an annual dividend rate of $1.56 per share, payable on June 1, 2014.
  • On Jan. 30, Moody's Investors Service upgraded the company's corporate credit rating to Baa1 from Baa2, with a stable outlook.

USE OF NON-GAAP FINANCIAL MEASURE

As noted in this news release, in addition to presenting our earnings information in conformity with Generally Accepted Accounting Principles, the company provided non-GAAP earnings data reflecting adjustments for special items as specified in the GAAP to non-GAAP adjustment reconciliation table below. Net income (loss), as adjusted, is defined Net income (loss), adjusted for expenses, gains and losses that the company believes do not reflect the company’s core operating performance. Black Hills believes that non-GAAP financial measures are useful to investors because the items excluded may not be indicative of the company's continuing operating results. Company management uses these non-GAAP financial measures as an indicator for planning and forecasting future periods. These non-GAAP measures have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. The presentation of these non-GAAP financial measures should not be construed as an inference that future results will not be affected by unusual, non-routine, or non-recurring items.

Gross margin (revenue less cost of sales) is considered a non-GAAP financial measure due to the exclusion of depreciation from the measure. The presentation of gross margin is intended to supplement investors’ understanding of operating performance. Gross margin for our Electric Utilities is calculated as operating revenue less cost of fuel, purchased power and cost of gas sold. Gross margin for our Gas Utilities is calculated as operating revenues less cost of gas sold. Our gross margin is impacted by the fluctuations in power purchases and natural gas and other fuel supply costs. However, while these fluctuating costs impact gross margin as a percentage of revenue, they only impact total gross margin if the costs cannot be passed through to customers. Gross margin measure may not be comparable to other companies’ gross margin measure. Furthermore, this measure is not intended to replace operating income as determined in accordance with GAAP as an indicator of operating performance.

First Quarter 2014 Compared with First Quarter 2013

Gross margin increased primarily due to $2.0 million on increased electric retail megawatt hours sold, and a return on additional investments which increased base electric margins by $3.0 million and increased rider margins by $3.3 million. These increases are partially offset by a charge to gross margin of $0.4 million reflecting a power cost sharing mechanism in place at Cheyenne Light, a $0.4 million decrease from wholesale quantities sold, a $0.9 million decrease from contract pricing for industrial customers, and a $1.9 million decrease resulting from energy cost adjustments.

Operations and maintenance increased primarily due to an increase in employee costs and property taxes.

Interest expense, net decreased primarily due to refinancing higher cost debt refinanced in the fourth quarter of 2013.

Income tax benefit (expense): The effective tax rate is higher in 2014 primarily due to the research and development tax credit not being extended to 2014. The first quarter of 2013 reflected the entire year of the 2012 research and development tax credit due to retroactive reinstatement in January 2013 by Congress of the credit.

First Quarter 2014 Compared with First Quarter 2013

Gross margin increased primarily due to colder weather than the same period in the prior year resulting in higher residential, commercial, and transport volumes sold. Heating degree days were 7 percent higher for the three months ended March 31, 2014, compared to the same period in the prior year and 14 percent higher than normal.

Operations and maintenance increased primarily due to an increase in employee costs and property taxes.

Interest expense, net decreased primarily due to refinancing higher cost debt in the fourth quarter of 2013.

Income tax benefit (expense): The effective tax rate for 2014 was slightly lower than 2013 due primarily to an increase in an estimated flow-through tax adjustment.

Non-Regulated Energy Group

Net income (loss) from the Non-regulated Energy group for the three months ended March 31, 2014, was $8.5 million, compared to Net income (loss) of $6.6 million for the same period in 2013.

First Quarter 2014 Compared with First Quarter 2013

Revenue increased primarily due to an increase in prices on delivered megawatt hours.

Depreciation and amortization was comparable to the same period in the prior year. The generating facility located in Pueblo, Colo., is accounted for as a capital lease under GAAP; as such, depreciation expense for the original cost of the facility is recorded at Colorado Electric for segment reporting purposes.

Interest expense, net decreased primarily due to refinancing higher cost project debt and settling associated interest rate swaps in the fourth quarter of 2013.

Income tax benefit (expense): The effective tax rate in 2013 was favorably impacted by a state tax adjustment.

First Quarter 2014 Compared with First Quarter 2013

Revenue increased primarily due to an 11 percent increase in price per ton sold and a 3 percent increase in tons sold. Approximately 50 percent of our coal production is sold under contracts that include price adjustments based on actual mining costs, including income taxes.

Operations and maintenance was comparable to prior year, reflecting a lower stripping ratio that drove a decline in overburden removal costs, and a favorable coal tax adjustment of $0.7 million, partially offset by an increase in repairs and maintenance.

Income tax benefit (expense): The increase in the effective tax rate in 2014 is due primarily to the reduced impact of the tax benefit of percentage depletion.

Average well-head price $ 90.75 $ 3.22 $ 87.78 $ 1.87
 

First Quarter 2014 Compared with First Quarter 2013

Revenue decreased primarily due to a 3 percent decrease in production primarily driven by normal declines on non-operated crude oil volumes sold, partially offset by a 13 percent increase in the average hedged price received for natural gas sold, and a 1 percent increase in the average price received for crude oil sold.

Operations and maintenance costs increased primarily due to higher non-operated well costs, higher production taxes and ad valorem taxes on higher natural gas revenue.

Depreciation, depletion and amortization increased primarily due to a higher depletion rate.

Income tax (expense) benefit: Each period presented reflects a tax benefit that was favorably impacted by the tax effect of essentially the same amount of estimated percentage depletion deduction.

Corporate Activities

First Quarter 2014 Compared with First Quarter 2013

Net income (loss) for Corporate activity was $0.3 million for the three months ended March 31, 2014, compared to net income (loss) of $5.7 million for the three months ended March 31, 2013. The variance from the prior year was primarily due to:

  • The settlement of the de-designated interest rate swaps in the fourth quarter of 2013 resulted in no mark-to-market activity for the three months ended March 31, 2014, compared to a mark-to-market gain of $7.5 million recorded for the three months ended March 31, 2013.
  • The income for the three months ended March 31, 2014, included lower interest expense as compared to the three months ended March 31, 2013, as a result of lower interest rate debt from refinancing activities in fourth quarter 2013, and the avoided settlement cost on the de-designated interest rate swaps, which were terminated in fourth quarter 2013.

All statements, other than statements of historical facts, included in this news release that address activities, events or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements. This includes, without limitations, our 2014 earnings guidance. These forward-looking statements are based on assumptions which we believe are reasonable based on current expectations and projections about future events and industry conditions and trends affecting our business. However, whether actual results and developments will conform to our expectations and predictions is subject to a number of risks and uncertainties that, among other things, could cause actual results to differ materially from those contained in the forward-looking statements, including without limitation, the risk factors described in Item 1A of Part I of our 2013 Annual Report on Form 10-K filed with the SEC, and other reports that we file with the SEC from time to time, and the following:

  • The accuracy of our assumptions on which our earnings guidance is based;
  • Our ability to obtain adequate cost recovery for our utility operations through regulatory proceedings and favorable rulings in periodic applications to recover costs for capital additions, plant retirements and decommissioning, fuel, transmission, purchased power, and other operating costs and the timing in which new rates would go into effect;
  • Our ability to gain regulatory approval and favorable regulatory treatment for putting generation into rate base;
  • Our ability to complete our capital program in a cost-effective and timely manner, including our ability to successfully develop our Mancos Shale reserves located in the San Juan and southern Piceance Basins;
  • Our ability to provide accurate estimates of proved crude oil and gas reserves and future production and associated costs; and
  • Other factors discussed from time to time in our filings with the SEC.

New factors that could cause actual results to differ materially from those described in forward-looking statements emerge from time-to-time, and it is not possible for us to predict all such factors, or the extent to which any such factor or combination of factors may cause actual results to differ from those contained in any forward-looking statement. We assume no obligation to update publicly any such forward-looking statements, whether as a result of new information, future events or otherwise.
