Analyst · this time, I would like to turn the conference call over to Dave Dragics, Senior Vice President of Investor Relations for CACI International. Please go ahead, sir
Well, thank you, Dave, and good morning, everyone. Thanks for joining us to discuss fiscal year 2018 first quarter results. With me this morning are John Mengucci, our Chief Operating Officer; Tom Mutryn, our Chief Financial Officer; DeEtte Gray, our President of U.S. operations; and Mr. Greg Bradford, President of CACI Limited, who is joining us from the United Kingdom.
Last night, we released our first quarter results for fiscal year 2018. We also raised net income and earnings per share guidance. This morning, I'll provide you an update on the quarter results and some strategic positioning. Tom is going to give you details on the financials and John will cover the operational aspects of the first quarter.
Let's turn to Slide 4 in the deck please. I'll start with a quick overview. Operations delivered right in line with our revenue and profit plan for first quarter, generating positive organic revenue growth for the third consecutive quarter and getting our FY '18 plans started in excellent shape.
Our net income and earnings per share benefited from a tax reduction associated with share-based compensation accounting, which Tom is going to elaborate on in just a moment.
As a result, we raised our net income and EPS guidance accounting for this benefit. We also continued to track record strong flow cash flow generating $80 million of operating cash in the quarter.
Turning to contract awards. We won $1.2 billion in the quarter, which at first appears significantly lower than what we have done in previous years. The key factor to this quarter was that there was a significant number of short-term recompete bridges, which contributed fractional value to our total awards in the quarter, despite being incredibly positive for us in terms of our outlook for the year.
John will have more to say in that just a moment. That said, we won a material amount of new business at the 60% level of our overall awards. I really liked the quality of the bids and solutions that we submitted this quarter. There were a couple of outcomes which I would've loved to have seen go our way. But all-in-all, I think we had a really solid start to first quarter and puts us in a great place.
Our strategy, we'll continue to bid larger, bid less last and win more, has been very successful the last two years with full-year book-to-bills of one 1.4x in both '16 and FY '17.
This strategy also returned to company to organic growth and built a significant backlog. I'm confident our strategy will continue to serve us well as we execute a high-quality pipeline within a large and increasingly larger addressable market.
Let's turn to Slide 5, current indicators are that we will probably have, and I emphasize probably, a fully-appropriated government fiscal 2018 budget in place before year end 2017. There has been movement on both the House and Senate side but authorization and appropriation bills have yet to be passed.
If enacted, the current budget numbers will drive increased Defense, Intelligence and Homeland Security spending, which will be positive for CACI, our industry and particularly, our country. In closing, our strategy is working. We continue to win new business and execute with quality and value. We are pursuing larger contracts with a particular emphasis on solution content. And we are investing in growth initiatives across our 12 market areas.
CACI will also continue to be a strategic consolidator through our M&A program as we deploy capital for growth. All of this gives me confidence in our continued success and our ability to achieve our long-term financial goals of organic revenue growth 1 to 4x -- 1% to 4% better than our addressable market, in addition to expanding our margins by 10 to 30 basis points annually.
Now I'm going to turn it over to Tom to take you through the details of the financials. Tom?
