Thanks, Rick. Yesterday, we issued a press release announcing our fourth quarter results. As you review this release, please note that we have included adjusted EBITDA and certain organic revenue amounts, both non-GAAP financial measures, to our release and comments. See Slide 11 through 14 for a reconciliation of the non-GAAP measures to the GAAP measures in the slide presentation provided for this call.
Moving to Slide 3. Revenue for the quarter increased year-over-year to $318 million, an increase of 4.7%. After excluding storm restoration services of $2.3 million from the current quarter and $14.1 million in the year-ago quarter, revenue grew organically 9%.
Volumes during the quarter were strong from telephone companies as a whole with most companies growing meaningfully while still carefully managing routine capital and maintenance expenditures, and spending by cable customers also increased year-over-year after excluding storm restoration services.
Gross margins decreased by 55 basis points year-over-year, reflecting an increased portion of revenues arising from the provision of materials to customers as well as a year-over-year decline in storm restoration services, offset in part by a decline in fuel expense.
General and administrative expenses were essentially unchanged as a percentage of revenue year-over-year, reflecting continued cost discipline.
All of these factors produced adjusted EBITDA of $40.5 million for the fourth quarter, an increase of 1.7% from last year.
Net income of $0.39 per share for the fourth quarter slightly improved from last year's earnings per share of $0.38. And liquidity was solid in the quarter with cash and availability under our credit facility at the end of the quarter totaling $239 million after repurchasing 102,200 shares of common stock.
Going to Slide 4. During the quarter, we experienced the effects of a steady industry environment. Revenue from CenturyLink was $43.2 million or 13.6% of revenue. CenturyLink was our largest customer and grew 27.4%. AT&T was our second largest customer at 12.7% of total revenue or $40.3 million. Revenue from Comcast was $40 million or 12.6% of revenue. Comcast was our third-largest customer and grew over 5% year-over-year. Verizon was Dycom's fourth largest customer for the quarter at 12.2% of revenue or $38.8 million. Verizon grew 16.1%. Revenue from Windstream was $32.1 million or 10.1% of revenue. Windstream was our fifth largest customer and grew over 70% year-over-year.
Altogether, our revenue grew 9%, representing our sixth consecutive quarter of organic growth. Our top 5 customers combined represented 61.1% of revenue, growing 9.5%, while all other customers increased 8.3%.
Now moving to Slide 5. Backlog at the end of the fourth quarter was $1.565 billion versus $1.744 billion at the end of the third quarter, a decrease of approximately $179 million. Of this backlog, approximately $909 million is expected to be completed in the next 12 months. Both backlog calculations increased significantly year-over-year, reflecting solid performance as we continue to book new work and renew existing work.
With Charter, we renewed cable construction and maintenance service agreements for the states of Illinois, Missouri, Tennessee, Alabama and Massachusetts. For Comcast, we renewed a construction and maintenance agreement and cable installation services agreement, both in the state of Illinois. With Verizon, we secured a 3-year facility-locating agreement in California; from Crown Castle, a network construction project in Florida; and finally, we secured rural broadband projects in a number of states including Oregon, New Mexico, Kentucky, West Virginia, Virginia, Vermont and South Carolina.
Headcount declined slightly during the quarter to 8,111.
Now, I will turn the call over to Drew for his financial review.
