Thanks, Steve. And good morning, everyone. Going to Slide 8. Contract revenues for Q3 of 2015 were $492.4 million and organic growth was at 13.4%, reflecting growth from several key customers, offset by declines on stimulus projects. Businesses acquired in the first quarter of 2015 and the fourth quarter of 2014 contributed, in aggregate, $8.9 million of revenue in the current period.
Gross margins increased 334 basis points, with a better mix of work types, lower fuel prices and improved productivity with more favorable weather compared to Q3 '14.
G&A, as a percent of revenue, is slightly down year-over-year and reflects our scale of operations.
Adjusted EBITDA increased to 12.8% of revenue or $63 million, compared to 9.3% or $39.6 million in the year-ago period. The strength of the performance this quarter resulted in earnings per share of $0.58, compared to $0.23 in Q3 '14.
With the increase in pretax income during the year and projected for our fourth quarter, our effective tax rate came in at 37.2% for Q3, which was favorable to our expectations. The difference in the effective rate contributed approximately $0.02 of EPS in the quarter compared to our previous expectations. We expect our Q4 effective tax rate to be 38.5%.
Turning to Slide 9. Our cash flows and balance sheet contribute -- continue to reflect the strength of our business, and our liquidity is over $400 million, with cash on hand and availability on our credit agreement.
At the end of Q3, we entered into an amended 5-year, $600 million credit agreement, which includes a term loan of $150 million and revolving facility of $450 million. We ended the quarter with the outstanding balance on the term loan and approximately $16.3 million drawn on the revolving facility.
Operating cash flows of $40.3 million reflect solid earnings and changes in working capital.
During Q3, our combined DSOs of AR and cost in excess of billings net declined by 4 days to 92 days as collections improved.
During the quarter, we collected approximately $7.1 million of past due balances from a customer on a stimulus project. This project has restarted and is progressing towards completion. Subsequent to the end of the quarter, we received an additional $5.8 million from this customer. The remaining past due balance is now $7.2 million, which we expect to collect over the next couple of quarters.
Capital expenditures, net of disposals, were $35.3 million and gross CapEx was approximately $38.1 million. We expect our net CapEx for fiscal 2015 to come in near $90 million, reflecting robust opportunities in the business.
During the quarter, we spent $13.5 million to repurchase 275,000 shares of our common stock at an average price of $49.24 per share.
Subsequent to the end of the quarter, we completed an acquisition of a small contractor in the upper Midwest for a purchase price of approximately $6.8 million.
Now going to our outlook on Slide 10. As we look ahead to Q4, we anticipate revenues which range from $550 million to $570 million. We expect firm and strengthening end market opportunities, increased demand by several large customers, including 1 gigabit deployments and customers where we are growing core market share, and lower revenue on stimulus projects as that program nears completion.
Gross margin percentage is expected to expand and reflects a solid mix of customer growth opportunities.
Total G&A costs are expected to range from 8.3% to 8.5% of revenue, reflecting our scale and higher performance-based compensation, including share-based award expense.
Depreciation and amortization, on a combined basis, is expected to range from $24.9 million to $25.4 million. Interest expense is expected at approximately $6.8 million. Other income from asset sales is expected to range from $1.3 million to $1.7 million. Taxes are expected to be 38.5% for Q4 '15. The applicable factors are expected to generate an adjusted EBITDA margin percentage which expands from the Q4 '14 result, and earnings which are currently expected to range from $0.74 to $0.82 per diluted share. We expect approximately 35 million diluted shares during Q4 '15, with shares gradually increasing in subsequent quarters.
Now going to Slide 11. Looking ahead to Q1 of fiscal 2016, our expectations currently reflect: Revenue growth of high single to low double-digits percent compared to Q1 '15, including revenues of recently acquired companies. We expect margins to increase over the Q1 '15 result. G&A expense is expected to decrease slightly as a percentage of revenue year-over-year and include noncash stock-based compensation of approximately $4.5 million. Adjusted EBITDA margin percentage is currently expected to increase from Q1 '15. Other factors influencing results include depreciation and amortization on a combined basis, which is expected to range from $25.3 million to $25.8 million. Interest expense of approximately $6.8 million, and other income from asset sales which ranges from $1.4 million to $1.8 million.
Finally, as a result of our 52 -- 53-week calendar, I'd like to remind you that our fiscal 2016 will include 53 weeks of operations. Q1, Q2 and Q3 will all have 13 weeks of operations, and our fiscal Q4 of 2016 will have 14 weeks of operations.
Now, I will turn the call back to Steve.
