Thank you, Glenn.
For those who have followed us over the past year or so, you know that our focus has been on strengthening our foundation and getting our company on track to generate consistent and sustainable profitability while building our cash position. The model we employed was based on achieving breakeven when revenue is light. And in periods when revenue is stronger, we would be positioned to add significant profits to the bottom line with minimal impact to our cost structure. We have successfully realigned our organization, invested in process excellence. And after the past 18 months of action, we now have the right model. This is reflected in our fiscal 2017 year-to-date results, as we've generated a $13.7 million improvement in non-GAAP operating income versus the prior year. Also on year-to-date basis, adjusted EBITDA of $6.2 million marks a $13.3 million improvement, and our net cash position has increased by $9.4 million.
As for the third quarter, we were again profitable on both a non-GAAP operating and net income basis. And we posted adjusted EBITDA of $2 million. We accomplished this on revenue of $58.7 million, which is just below the guidance we provided last quarter. Our Q3 revenue was impacted by some projects which were pushed out of the quarter to future periods, most of which we anticipate will materialize in the first half of fiscal 2018.
Our Q3 book-to-bill was slightly under 1. Similar to my comments regarding revenue, some anticipated bookings were pushed out as well. We expect Q4 bookings to be stronger and for the momentum to carry through into fiscal 2018. As I've mentioned previously, given the longer-term sales cycle of private network deals and the binary rate nature of our Private Networks business, it's better to look at bookings over a longer horizon. For example, our book-to-bill on a trailing 12-month basis is over 1, and this was the case for both North America and international.
And comparing our fiscal 2016 and 2017 third quarters, we generated a $7 million improvement in non-GAAP operating income and $6.8 million improvement in adjusted EBITDA. Further, our non-GAAP gross margin rate of 30.2% increased 630 basis points and was in line with what we had guided.
On the expense side, non-GAAP operating expenses were $17 million, which represents a reduction of over 18% compared to Q3 of the last fiscal year. There were some nonrecurring items, but overall we lowered our fixed expenses further and now expect our normalized run rate to be more like $18 million to $18.5 million per quarter, an improvement of approximately $4 million on an annualized basis from our previous guidance.
Our balance sheet also continues to improve across the board. Our cash position of approximately $40 million marks a $4.9 million increase over Q2 and we generated cash from operations of $5.1 million. We have now generated cash from operations in 7 of the past 8 quarters. Additionally, our cash conversion cycle continues to be near the best levels in our history. Ralph will provide more details around our balance sheet shortly.
I'm very pleased with our performance thus far in fiscal 2017, as we exceeded our profitability and cash targets with a much stronger foundation in place to take the business forward. Our culture continues to pursue process excellence. And we now are increasing our focus, investments and energy towards top line growth. Our optimism is supported by our strong backlog in a growing funnel of opportunities. Maintaining and servicing our large installed base will remain a critical part of our growth strategy, and we have a highly targeted sales approach for securing new customers.
Another key driver of our positive view is the strength of our offering. We have invested and innovated in areas that give us the best possible competitive position, and recently, we've had some major breakthroughs. We just introduced the WTM 4000, the highest-capacity radio ever built. The WTM 4000 expands the capabilities of our microwave radio portfolio and opens up growth opportunities both near and longer term. After a strong debut at Mobile World Congress in early March, we held an interactive launch event; and had over 600 attendees, with more than 1/3 of them new potential customers. We are now actively building our funnel across both the service provider and private network segments; and gearing up for the anticipated general release early in our next fiscal year, 2018. Additionally, we recently unveiled new low-latency products targeting the financial services segment, products that are used in long-distance networks for trading applications. And in our third quarter, we received multiple customer orders for the new versions.
Per our announcement earlier this week, we also invested in expanding the data-carrying capacity of our IRU 600 product line. We have a large installed base utilizing the IRU 600. And our North American service provider customers can benefit significantly by seamlessly upgrading their networks with our new offering. This is also the core product for our private network applications in North America. And adding this capability assures future support as high-definition video, security and surveillance and other high-bandwidth mission-critical applications evolve. Our continued investment in networking software for our CTR microwave router platform has created incremental license revenue opportunities, along with the potential of further improving our gross margins. The value proposition of a CTR platform is instrumental in defending our incumbency in key customer accounts while putting us in a position to win multiple large private network contracts. We're investing in solutions that will help us drive growth and expand our reach. Innovation will continue to be a critical component. Based on our offerings; our incumbent positions and customer relationships; and the many opportunities ahead of us within public safety, government agencies, utilities, financial services and with service providers globally, we feel we are well positioned to win market share and further improve our financial performance.
Turning to our near-term outlook. In my remarks last quarter, I provided guidance for the second half of the year. Now with our results in for Q3, I'd like to provide some updates.
As I referenced earlier, primarily as a result of the pushout of projects, our fourth quarter revenue should come in between $57 million to $62 million, though our bookings are anticipated to increase significantly. In addition, some of the orders we received in Q3 have a longer conversion to revenue than we originally had anticipated. For example, the low-latency orders we received in Q3 are currently not expected to start shipping for revenue until the first quarter of fiscal 2018. Gross margins are expected to remain strong, and our prior guidance is intact. We expect our fourth quarter gross margins to be approximately 30%.
As mentioned earlier, with the improvements in our operating structure and reduction in fixed expenses, we now believe our normalized run rate will be $18 million to $18.5 million, with Q4 expected to come in towards the higher end of this range due to some variable expenses targeted to generate growth. This should result in Q4 non-GAAP operating income tracking around breakeven with positive adjusted EBITDA. Additionally, we do expect a slight cash usage of cash in the quarter, although we expect to finish the fiscal year with a significant increase in our cash balance versus the prior year.
I'll now turn the call over to Ralph. Ralph?
