Now I'll turn the call over to Vic.
Thanks, Kate, and good afternoon. Before I give my perspective on the quarter, I'll turn it over to Gary for a few financial highlights.
Thanks, Vic. When we laid out our detailed guidance at the beginning of the year, we noted that our quarterly earnings profile was once again back-end loaded from an EPS perspective. In that initial guidance, we also projected a more heavily weighted Q4 than previous years, given the timing of several large projects across the company. As we sit here at the halfway point, the year is playing out a bit ahead of plan, and the quarterly profile we projected at the start of the year is being delivered as expected. Moving on to the Q2 results, in February, Q2 EPS was projected to be in the range of $0.37-$0.42 a share on a GAAP basis. Additionally, we indicated our GAAP earnings were impacted by some non-cash purchase accounting charges related to our recent acquisitions.
When we described and quantified these incremental charges related to the inventory step-up at Mayday, as well as additional or incremental non-cash depreciation and amortization charges that were expected to be incurred as a result of our recent M&A activities. As noted in the release, we delivered Q2 GAAP EPS of $0.43, which beat the top end of our expected range. The better-than-expected earnings were primarily driven by the continued strength of our commercial aerospace platform, as well as significantly higher, higher Navy and space products delivered in the quarter, coupled with lower corporate spending. Westland and Mayday delivered a combined $15 million in sales in Q2, along with solid EBITDA contributions. I'll remind you in Q2 that we recognized the final piece of Mayday's non-cash inventory step-up charge, which was approximately $1 million.
And as you can see from the financial tables within the release, depreciation and amortization increased $1.7 million in Q2 compared to the prior year. So on an EBITDA basis, we increased our Q2 contribution significantly, despite incurring the noted inventory step-up charge. Our Q2 2017 EBITDA increased 19% to over $25 million compared to Q2 2016 as adjusted. A few other Q2 and year-to-date highlights include the continued strength of our entered orders and the resulting growth in our March 31 backlog, especially as noted in Technical Packaging and Test, where we recorded Q2 book-to-bill of 1.3x and 1.2x, respectively.
Doble also reported a favorable book-to-bill, and Filtration's 0.9x is not of concern as this reflects higher sales at VACCO and Westland related to the runoff of large, multiyear procurements of submarine projects, coupled with the continued delivery of VACCO's space components for the SLS program. Year to date, I'm pleased to report that all four operating segments delivered a positive book-to-bill, which increased our backlog by $42 million, or 13% from the start of the year. The strength of our orders and the resulting $375 million in backlog provides additional confidence supporting our outlook for the back half of the year. Additionally, in Q2, we delivered another strong quarter of cash flow, which brings our six-month cash flow provided by operating activities to $37 million, which is well ahead of plan.
At March 31st, our net debt was $116.5 million, with a very reasonable leverage ratio of approximately 1.5x. Given the solid position we are in at the halfway point, our EPS and EBITDA outlook for the balance of 2017 remains consistent with the expectations communicated earlier. We continue to expect 2017's EBITDA to increase between 21% and 23% and to be in the range of $122 million-$124 million, compared to 2016's adjusted EBITDA of $101 million.... We remain well positioned to achieve our financial goals as we continue to see meaningful sales, EBIT, and EBITDA growth across each of our business segments. In the longer term, we expect to exceed the growth rates of our defined peer group in the broader industrial market in total.
Our Q3 EPS guidance is projected to be in the range of $0.46-$0.51 a share on a GAAP basis, and as a reminder, this includes the quarterly impact of the incremental depreciation and amortization from M&A, as communicated previously. Now I'll turn it back over to Vic.
Thanks, Gary. I also am pleased with our second quarter performance and with the way we wrapped up the first half of the year. Our second quarter sales came in on plan, and we exceeded our internal targets on EBIT, EPS, cash flow, and orders. As Gary mentioned, our current backlog level is the highest it's been in a number of years, especially in Test, which bodes well for meeting our commitments over the balance of the year. We continue to deliver on our results across the four operating segments, and I believe our six months results validate our strategy and demonstrate one of the major benefits of maintaining our multi-segment business platform. Given the diversity and strength of our end markets, it allows us to manage around the normal operational and project timing issues and provides us with several alternative paths to achieve success.
Our results communicated through today demonstrate what I believe we do best. Collectively, our management teams continue to execute the plan and remain focused on delivering sustainable operational results. This gives us the chance to exceed expectations despite the normal business challenges that industrial companies face regularly. Since Gary covered the detailed financial analysis commentary, I'll focus my comments on the balance of 2017. Given our guidance for the third quarter, and by reaffirming our full-year EPS expectations, it's obvious we are counting on a very strong performance in the fourth quarter. I'm confident in our ability to deliver these commitments over the balance of the year, supported by the strength of our current backlog and the detailed insight by program supporting this ramp up in sales and earnings. So here's a few brief comments on individual businesses.
In Filtration, we continue to expect to deliver solid results in sales growth, EBIT, and EBITDA contributions and cash flow. Mayday and Westland have several opportunities to provide further growth over the balance of the year, as well as in the out years, given the bid and proposal activities we're currently addressing. Since becoming part of our Filtration group, we've had several current customers reach out to Mayday with new business opportunities, as they want to consolidate their supplier base. Based on experiences with our legacy filtration companies, these customers feel comfortable adding Mayday to their list of preferred suppliers. Additionally, in Filtration, we remain well positioned on several fronts, including the continued upcycle in commercial aerospace, growing opportunities in space, and unparalleled technology on Navy submarines and surface ships, which are critical to our national security.
Our Technical Packaging group's outlook is solid, and as noted previously, we're making additional investments to add production capacity both domestically and internationally. With the recent acquisitions, we now have meaningful scale and market leadership positions across several growth markets and geographies, which allow us to address the needs of our global customers in the medical, pharmaceutical, and consumer markets. The opportunities we're addressing set us up nicely today and in the out years. On to Doble. We continue to see some easing of the spending constraints within the electric utility capital budgets, and we've set our expectations around this view. The growth opportunities we're seeing today will be coming from our new products, such as the M-Series, doblePRIME, and our DUC Enterprise solution. Coupled with the strength of our software offerings, I remain enthusiastic about Doble's future.
In March, we hosted our eighty-fourth annual conference, which as in the past, was very well attended. The enthusiasm, continuing loyalty demonstrated by our customers is outstanding. At Test, our sales and operating performance gained momentum in the second quarter as we began shipping product to one of our large key customers. I was really pleased to see the favorable impact on the EBIT from the cost savings we implemented last year. As the year progresses and the strong backlog converts into meaningful increases in quarterly sales, we expect these higher sales to result in EBIT margins in the third and fourth quarter at meaningful higher levels than today. On the M&A front, we are currently very engaged in several opportunities, which provide confidence that we will add non-organic growth this year to supplement our current outlook.
Wrapping up, I'm pleased with our second quarter and first half results, and I remain confident that our outlook for the balance of 2017 remains solid. Our focus remains constant, to continue to improve our operational performance and execute on our growth opportunities, both organically and through acquisitions. That's how we will increase shareholder value. I'll be glad to answer any questions you have.
