Great. Thanks, Dave, and good morning, everyone. We're pleased with our first quarter financial performance. When you review our Q1 results for 2017 versus 2016, you see the earnings power of our Gas Utilities with the addition of a full quarter of SourceGas, as Dave mentioned. Despite milder winter weather than normal, our Gas Utilities earnings increased substantially year-over-year. Additionally, we're pleased with the growth in our Electric Utilities from new generation investments and continued solid performance from our Power Generation and Mining segments.
On Slide 9, we reconcile GAAP earnings to earnings as adjusted, a non-GAAP measure. We do this to isolate special items and communicate earnings that better represent our ongoing performance. This slide displays the last 5 quarters and trailing 12 months as of March 31 for 2017 and 2016. As detailed on the slide, we experienced special items not reflective of our ongoing performance in each quarter of 2016 and Q1 of 2017. The first special item is noncash asset impairments at our Oil and Gas business that occurred last year. The second special item is acquisition-related expenses, such as advisory fees, financing and other third-party consulting costs associated with the SourceGas acquisition and integration. We completed nearly all the integration work related to the acquisition in 2016 and are finishing the few remaining projects in 2017. These acquisition expenses and impairments are not indicative of our ongoing performance and, accordingly, we reflect them on an as adjusted basis. Our first quarter as adjusted EPS was $1.41 per share compared to $1.23 for the first quarter last year. The earnings uplift in Q1 this year compared to Q1 last year was driven mainly by the first full quarter ownership of the SourceGas utilities. As you'll recall, we closed on the acquisition in mid-February last year. This quarter's results were strong despite milder weather than normal during the first quarter heating season at our Gas and Electric Utilities. Warmer-than-normal weather impacted EPS by an estimated $0.09 in the first quarter. And I'll discuss the impact of weather in more detail later. And as I mentioned on prior calls, we have seasonality in our earnings, with the highest earnings in the heating season represented by the first and fourth quarters. For the trailing 12 months, as adjusted EPS came in at $3.35 per share compared to $3.14 per share for last year, a nearly 7% increase.
Slide 10 displays our first quarter revenue and operating income. On the left side of the slide, you'll note that 2017 revenues for Q1 exceeded those in 2016 by 23%, mainly due to the addition of the SourceGas natural gas utilities. On the right side of the slide, you'll see that year-over-year operating income increased 33%, driven by a $28 million increase at the Gas Utilities, again, due to the addition of SourceGas for the full quarter. We also benefited from improved operating performance in the first quarter at our Electric Utilities, Oil and Gas and Corporate segments. The Power Generation and Coal Mining segments were essentially flat. I'll discuss each of the segments on the following slides. The improvement in the Corporate segment relates to the reduction in 2017 of internal labor charges to acquisition and integration activities. As I noted on the previous slide, with the integration substantially complete, our employees have largely moved on to other projects and initiatives.
Slide 11 displays our first quarter income statement. Gross margin, operating expenses and DD&A all increased comparing Q1 2017 to Q1 2016, mainly as a result of the SourceGas acquisition. Given our successful execution of integration activities during 2016, the increase in operating expenses was moderated. As a result, operating income before special items increased 33% year-over-year. For Q1 2017, the only special item was minimal acquisition-related costs. Q1 2016 included special items for Oil and Gas impairments and more significant acquisition-related costs. Interest expense increased year-over-year related to increased outstanding debt from the acquisition. The increase was mitigated through successful Q3 2016 refinancings of debt we assumed from SourceGas, and from favorable short-term rates from our newly implemented commercial paper program that Dave mentioned. The effective tax rate for the quarter was just under 30% and benefited from a onetime $2 million interest reversal associated with a carryback claim, plus $1.4 million in production tax credits from our Peak View Wind Farm, which went into service in late 2016. As you'll recall, in Q1 last year, we had a settlement with the IRS as well as a tax depletion methodology change, which combined, resulted in an effective rate well below normal for 2016. In the second quarter of 2016, we sold a 49.9% interest in Colorado IPP. The $3.6 million reduction in net income available for our shareholders represents the ownership interest in that facility by a third party. I'll talk more about this on the Power Generation slide. Moving to the as adjusted net income line. We reported $77 million for the quarter compared to $64 million for Q1 2016, a 21% increase. Diluted shares increased in 2017 compared to 2016 due to nearly 2 million shares of equity issued in the last 3 quarters of 2016 on our at-the-market equity program. Also, the application of the treasury stock method related to our unit mandatories added approximately 1.6 million shares to the Q1 2017 diluted share count compared to approximately 700,000 additional shares in Q1 of last year. Overall, as adjusted EPS grew $0.18 or 15% from the same quarter last year. EBITDA increased by $40 million or 26%. These strong results met our expectations despite the headwinds we faced from milder-than-normal weather.
Slide 12 displays our utilities gross margin and operating income. On the left side of the slide, you see the Electric Utilities gross margin increased in the first quarter by $6.3 million over 2016. The gross margin increases resulted from returns on the Peak View Wind and Colorado Gas Turbine Generation projects placed in service in late 2016, transmission investments and increased commercial and industrial load. Operating income increased by $3.2 million or nearly 8% for the first quarter compared to 2016. Despite the addition of generation and transmission projects, our Electric Utilities did a great job controlling cost increases with O&M only increasing $1.5 million comparing this year to last year. I'll also note a substantial component of the return on our Peak View Wind Project is realized through production tax credits, which come through reduced income taxes rather than through operating income. As I noted earlier, these credits amounted to $1.4 million in the first quarter. Moving to the right side of the slide, the improved results in our Gas Utilities for the first quarter were almost entirely explained by the addition of SourceGas. We closed the acquisition on February 12, 2016. So we picked up 42 days of SourceGas operating results in Q1 2017. Also, at our legacy Black Hills gas operations, we demonstrated improved operating income of $1.6 million, a 3.7% growth rate year-over-year, benefiting from strong cost management. As I mentioned earlier, we experienced warmer-than-normal weather during Q1, negatively impacting the EPS contribution from our Electric and Gas Utilities by approximately $0.09. Heating degree days were 11% below normal at the Electric Utilities and more notably 13% below normal at the Gas Utilities. Comparing to normal weather at our utilities for the first quarter, our gas utility gross margins were negatively impacted by an estimated $6.5 million, while the electric utility gross margins were negatively impacted by an estimated $800,000.
On Slide 13, you see the power gen operating income was effectively flat for the first quarter compared to 2016. The Power Generation business unit continues to realize strong contract availability with its generating units and continued its cash flow contributions to Black Hills. Our power gen segment includes the Colorado IPP plant, which was contracted -- which is contracted to our Colorado Electric Utility, plus 75.6 -- 76.5% ownership of the Wygen I plant, which is contracted to our Wyoming Electric Utility. Colorado IPP accounts for approximately 60% of the operating income in our power gen segment. These numbers include a 100% ownership of Colorado IPP. In the second quarter of 2016, we sold a 49.9% interest in Colorado IPP. We consolidated 100% of that unit's results in our financial statements and then backed out the 49.9% noncontrolling interest at the bottom of the income statement. Moving to the right side of the slide, our Mining segment operating income was also essentially flat compared to Q1 2016. For the quarter, revenue was up slightly as tons sold increased by 5% compared to last year, due primarily to a power plant outage last year. On the cost side, we enjoyed continuing mining efficiencies as we were able to move 19% more overburden in 2017 at a decreased per cubic yard cost. O&M was higher in 2017 than 2016, due primarily to a production tax valuation adjustment involving the prior year. Our mine continues to perform at a high level with sales almost entirely to on-site mine-mouth plants and roughly half our sales based on a favorable cost-plus mechanism.
Moving to Slide 14. At Oil and Gas, we reduced the operating loss in the first quarter to $3.7 million compared to an operating loss of $4.8 million in Q1 2016. The 2016 operating loss excludes asset impairment charges taken last year. First quarter volumes sold decreased as oil and gas production declined from the prior year due to divestures and natural decline curves. The decrease in volume was offset by slightly higher average commodity prices received, lower DD&A resulting from previous impairments and diligent G&A cost management, all of which have helped minimize the operating loss from the segment. We expect operating results to continue to improve at Oil and Gas as we move through 2017, focusing the segment on supporting our cost of service gas initiative. Also, we've made additional minor divestitures of noncore properties during 2017, bringing total sales proceeds to date up to approximately $12 million.
Slide 15 shows our capitalization. At March 31, our net debt-to-cap ratio was 66%, a reduction of 330 basis points from the same quarter last year. As we move forward, we expect the ratio to continue to decline through growth in our stockholders equity from earnings. We don't expect to add any significant debt in the near term, which I'll discuss on the next slide. And our internally generated cash flows will fund our CapEx and dividends for the next couple years. Additionally, we have $299 million of unit mandatories reported as debt on our balance sheet until those units convert in the second half of 2018. We're committed to maintaining our solid investment grade credit ratings and our forward -- forecasted metrics support those ratings.
Slide 16 demonstrates that we're in good shape relative to upcoming debt maturities. In the first quarter last year, we executed significant debt financings as we paid for the SourceGas acquisition. In the third quarter last year, we accessed the debt markets at a time when credit conditions were beneficial to successfully refinance debt we assumed through the acquisition and term out other upcoming maturities. We also successfully implemented a commercial paper program in Q1, which will help minimize short-term borrowing costs. I'll also mention that on the equity side, we issued nearly 2 million shares of stock through our at-the-market equity program in 2016, raising nearly $120 million through that program. While we will keep the program active to provide financing flexibility as we move forward, we intend to issue very few, if any, shares through the program in the near term.
Slide 17 demonstrates our track record of growing operating earnings and EPS. The midpoint of our 2017 as adjusted EPS guidance exhibits a full year of earnings contribution from the fully-integrated SourceGas transaction, taking the next step forward and continuing to build on our impressive track record of growing shareholder value as we serve our utility customers safely, reliably and efficiently.
On Slide 18, we're reaffirming our as adjusted 2017 earnings guidance of $3.45 to $3.65 per share. We're pleased with our operational execution despite mild weather in Q1.
And with that, I'll turn it back to Dave for his strategic overview.
