Thanks, Rick. Moving to Slide 4. Yesterday, we announced after the markets closed our execution of a definitive stock purchase agreement to acquire Quanta Services' Telecommunications Infrastructure Services Subsidiaries for approximately $275 million in cash. These subsidiaries represent substantially all of Quanta's domestic telecommunications infrastructure services operations. The purchase will be financed through a new $400 million senior secured credit facility. It is expected to close, subject to customary selling conditions, by December 31, 2012.
Going to Slide 5. This acquisition strategically strengthens our customer base, geographic scope and technical services offerings, reinforces our rural engineering and construction capabilities, wireless construction resources and broadband construction competencies, and creates scale as industry announcements indicates customer expenditures will be growing. It takes advantage of a very attractive financing environment to drive strong investment returns. And most importantly, brings us an experienced management team with a solid industry reputation.
Moving to Slide 6. The acquired subsidiaries operate nationwide from principal business locations in Arizona, California, Florida, Georgia, Minnesota, New York, Pennsylvania and Washington. They are currently serving over 300 customers in 49 states, and employ more than 2,400 personnel. For the trailing 12-month period to September 30, these subsidiaries generated revenues of approximately $535 million, of which approximately $138 million related to projects funded in part by the American Recovery and Reinvestment Act. Most importantly, these businesses have individually provided, literally, decades of dedicated service to our joint customers, we are proud to add them to our company.
Going to Slide 7. This charts represent the enhanced customer relationships and increase customer diversity created by this transaction. We believe the scale created is well-timed to take advantage of emerging growth opportunities and to provide even better service to our combined customers.
Moving to Slide 8. Financing for this acquisition will be provided by a new 5-year $400 million senior secured credit facility consisting of $125 million term loan A and a revolver. The new facility contains terms and covenants reflecting a larger combined business, and we expect ample cash flows to reduce borrowings in the near to intermediate term. The acquisition is structured as a purchase of assets for tax purposes, and accordingly produces attractive and substantial cash tax benefits. And as a result of all of these factors, we will possess a strong balance sheet and ample liquidity post closing.
Going to Slide 9. Looking ahead, we expect calendar year 2013 revenue for the acquired subsidiaries to range from $400 million to $450 million; onetime transaction and integration costs of approximately $12 million to $15 million. And excluding onetime costs, we are currently expecting $0.05 to $0.10 per share of earnings accretion on a first year basis after substantial first year non-cash amortization expense.
In sum, we are pleased to grow our company in a time of increasing opportunities with a strong complementary management team and dedicated employees.
Now moving to Slide 11 and the review of our first quarter fiscal 2013 results. As you review these results, please note that we have included adjusted EBITDA, certain revenue amounts excluding storm restoration services, certain expense amounts excluding acquisition related costs and adjusted earnings per share, all of which are non-GAAP financial measures to our release and comments. See Slides 19 through 22 for a reconciliation of the non-GAAP measures to the GAAP measures in the slide presentation provided for this call.
Revenue for the quarter increased year-over-year to $323.3 million, an increase of 1.2%. After excluding storm restoration services of $3.7 million from the year ago quarter, revenue grew 2.4%. Volumes during the quarter were solid from telephone companies as a whole, with some companies growing meaningfully while all carefully managed routine capital and maintenance expenditures. And spending by cable customers also increased year-over-year in line with spending by telephone companies.
Gross margins increased by 33 basis points year-over-year reflecting improved operating trends. And general and administrative expense were up slightly as a percentage of revenue year-over-year, reflecting increased non-cash compensation due to the timing and type of employee equity awards in recent periods, offset in part by continued good cost discipline. All of these factors produced adjusted EBITDA of $40.4 million for the first quarter or 12.5% of revenue.
Net income of $0.36 per share for the first quarter declined from last year's earnings per share of $0.38, reflecting higher non-cash compensation expenses and less other income as we reduced the amount of assets we sold during the quarter. After $27.7 million in operating cash flow in the quarter, liquidity was solid with cash and availability under our current credit facility, totaling $236 million after repurchasing 1,047,000 shares of common stock at an average price of $14.52.
Going to Slide 12. During the quarter, we experienced the effects of a steady industry environment. Revenue from CenturyLink was $44.4 million or 13.7% of revenue. CenturyLink grew 8.4%. AT&T was our second largest customer at 13.5% of total revenue or $43.7 million. Revenue from Comcast was $41.2 million or 12.7% of revenue. Comcast was our third largest customer and grew over 1.3% year-over-year. Verizon was Dycom's fourth largest customer for the quarter at 10.2% of revenue or $33 million. Revenue from Windstream was $30.3 million or 9.4% of revenue.
Altogether, our revenue grew 2.4% after excluding storm restoration services, representing our seventh consecutive quarter of organic growth. Our top 5 customers combined represented 59.6% of revenue, growing 1.8% organically, while all other customers increased 3.1%.
Now moving to Slide 13. Backlog at the end of the first quarter was $1.376 billion versus $1.565 billion at the end of the fourth quarter, a decrease of approximately $189 million. Of this backlog, approximately $822 million is expected to be completed in the next 12 months. Both backlog calculations were in line year-over-year, reflecting solid performance as we continue to book new work and renew existing work and look forward to substantial future opportunities.
With AT&T, we secured a new 3-year construction and maintenance services agreement in South Carolina, as well as expanding for 3 years an existing South Carolina agreement. For Charter, we secured an improvement project in Alabama. With Time Warner, we secured a 1-year facility locating agreement in California. From Questar, several pipeline construction projects in Utah. And finally, we secured rural broadband projects in a number of states including Kentucky, Georgia, North Carolina and Missouri. Headcount declined slightly during the quarter to 8,001.
Now I will turn the call over to Drew for his financial review.
