Ron Konezny - President, CEO, and Director
Thank you, Steve, and greetings to everyone on the call today. We've had a busy and productive quarter attacking the immediate objectives we discussed in last quarter's earnings call.
First, focus the business. We exited the end-to-end IoT solutions business. We returned Etherios to their core strength of implementing cloud solutions, and salesforce in particular. Our wireless design services group has been branded Digi and is working closely with our RF, embedded, and channel teams to bring incremental value to our Digi product customers. And our device cloud has also been branded Digi and is directed toward helping our customers manage and control their Digi products.
Secondly, increase profitability. We implemented a restructuring program in fiscal Q2 to improve our overall profitability and drive improved operating efficiency by eliminating areas of the business that were deemed nonessential to our strategy moving forward. In addition, spending is being scrutinized and rationalized within the various operating units to meet our business objective.
Lastly, driving growth. We kicked off key innovation projects across our product lines to position us to deliver on our future growth plans. Our product teams have executed well, producing year-over-year growth, with particular strength in our cellular and RF product lines. And we are attracting and keeping larger account opportunities.
In addition to these three major initiatives, we also accomplished the following. We announced a new Chief Financial Officer, Mike Goergen, who started this week. Mike's experienced leadership and talents will further sharpen the Company's processes and performance, which will lead to higher levels of productivity and profitability. Mike's skill set fits Digi well, with his prior success in accounting, tax, finance, supply chain, and information technology and systems.
We've also recovered from the supply chain disruption from November of last year. Fabulous efforts by our team strengthened our supply chain by increasing capacity and resiliency. This will improve our performance going forward and insulate us from further disruption.
To give you a feel about the scope of the recovery, we shipped a record number of XBee modules in fiscal Q2. We also aligned our customer and channel partners in Europe with our renewed M2M focus at a successful sales conference we hosted in Cannes, France, in February.
Our recent actions and initiatives have started to show evidence in our financial performance. Revenue improved nearly 16% from last year's fiscal second quarter. Year over year, our revenue performance improved across every geography. Both our products and services businesses improved quarter over quarter; and Digi has returned to operating, EBITDA, and net profitability.
To be sure, we have room for improvement to meet our potential. Our mature products as a whole decelerated faster than anticipated. We've taken corrective actions in both innovation and distribution. Our cash balance was lower than expected, impacted by higher accounts receivable balances and foreign currency values. And our gross margins were a bit lower than expected, but we are prepared to handle this dynamic as we take on higher-volume business to fuel growth.
Regarding our identity and Company strategy, we have progressed our thinking substantially; have had the opportunity to visit with our largest customers and partners; spend time with more of our incredible team; and talk with competitors, suppliers, and industry experts. As I mentioned on our last earnings call, Digi's leading attributes of quality, reliability, performance, and configuration have established our reputation as a mission-critical provider of M2M solutions.
Our breadth of offerings spans from creation, to deployment, to management. Through our embedded module and wireless design services groups, Digi is a key enabler of custom and customized M2M products. Our expertise in System-on-Module and wireless technologies allow our customers to build new products and bring them to market quicker and with higher quality and features to create M2M solutions.
Digi's customers and partners deploy our broad set of wired and wireless networking products. These complete box solutions have industry-leading warranties, flexible hardware and software architectures, and strong performance. Our device cloud platform allows customers to better manage their Digi products that are oftentimes deployed around the globe. And lastly, our Etherios team ports and actions machine data into cloud applications, where can be combined with other data to manage remote assets and field forces.
Digi's unique ability to create, deploy, and manage M2M solutions is both more advanced and broader than anything else in the market. The mission-critical segment of M2M is attracted to Digi, which coalesces around six key verticals. Let me provide a few current examples.
First, in energy, Digi's XP wireless sensors, combined with our gateways, provide essential communications and monitoring services for our energy customers. Second, in retail, Digi's cellular routers are used by Contour Network to secure very sensitive ATM connections.
Third, in industrial, a leading thermal imaging company shows Digi's ConnectCore 6 single-board computer for a new range of cameras for professional and commercial markets. Fourth, in medical, Digi's embedded modules and wireless design services provide faster time-to-market for certified medical equipment such as infusion pumps and telemedicine.
Fifth, transportation: Digi's device networking products are used by leading global delivery services companies to track parcels within the supply chain. And sixth, in government, the National Oceanic and Atmospheric Administration, or NOAA, is deploying Digi cellular routers as critical backup communications between their remote stations and NOAA's Radar Operations Center in Norman, Oklahoma.
During our fiscal third quarter, we will further sharpen our Company identity, value proposition, messaging, and performance. We look forward to providing an update on this important initiative in July, when our Company will celebrate its 30th anniversary.
I am incredibly proud of the Digi team. We've gone through a lot of change in a short period of time, and I'm grateful for the listening and feedback of everyone within Digi. We are developing a culture of caring about each other, our partners, and our customers, which will result in a culture of winning.
Over the past three months, I've had incredible interactions with our leaders, team members, customers, partners, and vendors. It's humbling to see the energy our Company has generated. We have a tremendous opportunity to build on the momentum generated.
In closing, I would like to give a special and heartfelt thank you to Steve Snyder, who will be retiring after a transition period with Mike Goergen. Steve has been a huge part of transitioning me to both Digi and the public market role of CEO. We will miss Steve dearly, and we wish him and his family nothing but good fortune.
Now, before handing the call to Steve, who will give a comprehensive update of our financial performance, I would like to welcome Mike Goergen to Digi.
Mike Goergen - SVP, CFO, and Treasurer
Thanks, Ron. I'm excited to join the Digi team. I look forward to meeting our analysts as well as working with the investment community. Since I just joined the Company Monday, I'm going to turn the call over to Steve so he can run through our financial performance. Steve?
Steven Snyder - Former SVP, CFO, and Treasurer
Thank you, Mike, and welcome to Digi.
Mike Goergen - SVP, CFO, and Treasurer
Thank you.
Steven Snyder - Former SVP, CFO, and Treasurer
We were pleased with our second-quarter financial performance from both a revenue and profitability standpoint. Starting with revenue, our total revenue grew 15.8% from the previous year. The key driver of this was total product revenue, which was up 18.6% from the previous year.
Product revenue from the growth product lines was up $9.6 million or 45.9% from the previous year, led by increases in cellular gateways and routers, which saw revenue grow by 60%. Volume in our energy and retail verticals paced this growth.
Our RF business also saw year-over-year growth in excess of 50%, which is higher than normal. We believe that about $1.5 million of this increase was due to the orders that could not be fulfilled in Q1 due to the impact of the fire at our Thailand subcontract manufacturer's location in November 2014.
As you will recall, we identified this timing issue last quarter, since the RF business was lighter than normal in the first quarter. By looking at the business on a year-to-date basis, our RF business is up 24%, which is at the high end of the range where we expect that business to perform.
Our mature product line revenue decreased by $2 million or 10.2%, which was faster than expected in the quarter, but not outside the range of 5% to 15% we've discussed before. Contributing to the decline was the absence of revenue from certain products that have been discontinued in the last 12 months. As Ron mentioned, we have taken steps designed to slow the rate of decline in this product set.
We were pleased with the positive movement in our services business during the quarter. Although revenues are down 5.2% year over year, it was our first meaningful sequential improvement since Q3 of 2013. This was paced by an increase in Etherios DRM consulting services revenue. As Ron mentioned, this business has been refocused on its core capability of CRM and service call implementations. This has generated an immediate positive impact on that group's revenues.
Geographically all regions performed well and exceeded Q2 2014 revenue performance. North American revenue in particular was strong and increased 18.4% over the year-ago quarter. Revenue in India increased by 3.7% compared to the year-ago quarter but was hampered by the weakening euro and British pound, resulting in a negative impact on revenue of $1.1 million. As I mentioned last quarter, about half of our European business is sold on local currencies.
Gross profit increased by $2.3 million in Q2 2015 compared to Q2 2014. Our gross margin was 45.3% compared to 47.5% in Q2 2014, a decrease of 2.2 percentage points. We continue to see pressure on our gross margins. Factors that affected our gross margins in Q2 included the following.
Product mix: as previously mentioned, revenue from cellular products led our increase in gross products revenue compared to the year-ago quarter. Our gross margins on cellular products and certain other growth products are lower than on our mature products. As our revenue from these products increases and our revenue from our core products and mature products decrease, we will see a continued negative pressure on our gross margins.
Large customer impact: a number of our large customers are growing. As Ron mentioned earlier, we are intent to position our Company to be a growth company. To that end, we will be far more sophisticated with our pricing to incent existing customers to purchase more product and to attract new customers. With that in mind, we expect there to be some pressure on our gross margins for the foreseeable future. However, we believe this is a small cost to driving the growth of the Company.
We incurred expenses in Q2 as a result of the SVI fire, primarily due to redirecting production to other, higher-cost subcontract manufacturers prior to SVI resuming full production. The sequential increase in the services business improved utilization rates of our service consultants. We expect that service gross margins will fluctuate in future periods due to the varying utilization rate, the repositioning of the business, and the scaling of the business to current and expected revenue levels in connection with the recent restructuring.
Our operating expenses in the second quarter of 2015 were $700,000 higher than the year-ago comparable quarter. This was driven primarily by restructuring expenses of $500,000 for our India and Etherios operations, where we reduced our workforce by approximately 60 people. As mentioned in the last quarter's call, we closed our facility in India in connection with this restructuring. Total annualized expense savings as a result of the restructuring of the India and Etherios operations are expected to be approximately $4 million to $5 million.
Other income included $1 million of insurance proceeds related to the replacement of our capital equipment destroyed in the fire at SVI. Net income for the quarter was $1.4 million or $0.06 per diluted share compared to net income of $700,000 or $0.03 per diluted share in Q2 2014.
Non-GAAP net income for the quarter was $1.1 million or $0.04 per diluted share compared to a net loss of $400,000 or $0.01 loss per diluted share for Q2 2014. We provided a full reconciliation table in the earnings release for your convenience.
Adjusted EBITDA for the second quarter was $2.7 million compared to $1.2 million for the second quarter of 2014. We removed the insurance proceeds from the second-quarter 2015 EBITDA calculation, as we consider this a nonoperating item, as detailed in the reconciliation table in the earnings release.
Moving to the balance sheet, cash and investments totaled $92.4 million, effectively flat with the prior quarter. This is a result of temporary increases in our working capital, primarily accounts receivable. Our accounts receivable is up due to our revenue performance and its timing within the quarter.
In addition, the weakening of the euro and British pound resulted in a decrease in cash as a result of the translation of local currency cash balances to US dollars. Our balance sheet continues to be robust, with a current ratio of 6.9 to 1 at March 31, 2015, compared to 6.8 to 1 at September 30, 2014. Digi remains debt-free.
Next, I'll provide guidance for the third fiscal quarter 2015. Digi projects revenue for the third fiscal quarter 2015 to be in the range of $51 million to $54 million, and net income per diluted share in a range of $0.02 to $0.05. For the full fiscal year, we have narrowed our guidance range and project revenues of $203 million to $210 million and net income per diluted share of $0.07 to $0.15.
This concludes my prepared remarks. At this time, Ron and I are pleased open the call for your questions. Operator?

(Operator Instructions) Mike Walkley, Canaccord Genuity.
Mike Walkley - Analyst
Thanks for taking my questions. I guess, Mike, look forward to meeting you. And Steve, it's been great working with you, and best wishes in your retirement.
Steven Snyder - Former SVP, CFO, and Treasurer
Thanks, Mike.
Mike Walkley - Analyst
Just maybe starting off for me on high-level questions for Ron: you've been there a relatively short time but already seem to have implemented quite a few changes. If you take a broad picture of Digi's portfolio, what are areas that you are seeing that you need to allocate more resources towards now that you've been there a while, and where you see the biggest opportunity to drive growth?
Ron Konezny - President, CEO, and Director
Yes, that's a good question. And when I got here, the Company was stretched pretty thin on the innovation side. In particular, as the Company was putting a lot of innovation effort into chasing IoT end-to-end solutions, that was also having an impact on starving the product line a bit. And so we have focused our engineering efforts, obviously, away from the IoT solutions, but we've also incrementally increased our efforts on our product lines.
The cellular and RF parts of our business, as Steve mentioned, are showing the greatest growth rates right now for us. But there are opportunities in embedded and in our mature portfolio as well that we have dedicated resources to innovations that we are very confident will pay off.
Mike Walkley - Analyst
Great. Thanks. And just building on that, maybe you can share some of your feedback. I know you've been visiting a lot of customers. And as you focus on some of those areas for innovation, what do you think is a realistic timeline to come up with the new products and take growth maybe to that next level as you reinvest in innovation?
Ron Konezny - President, CEO, and Director
Yes, it's another good question. We do have what we feel are some fairly short-term initiatives, especially projects that are software-oriented, where we can take an existing product and add new capabilities; download that capability, either to existing products in the field or, of course, as new products are shipped.
But we also have some projects that we think will impact fiscal 2016, because I'm really starting to imagine what fiscal 2016 is going to look like. And we want to make investments today that really position ourselves to continue momentum into that year. And that's going to be nicely complemented with our 2016 planning process that really kicks off in May -- I'm sorry, with our fiscal year ending in September. So we really want to be in a better position in July to sharpen that update.
Mike Walkley - Analyst
Okay, great. And then on the services side, with the change in the focus away from end-to-end solutions, revenue already had a nice uptick; how should we think about the revenue run rate for that business? I know it can be volatile. And with some of the restructuring in India, where could gross margins go to, just to help us in modeling that business?
Ron Konezny - President, CEO, and Director
It's a very good question. I think you also hit the nail on the head with -- again, we've got a couple services business in there. They can be volatile quarter to quarter due to their size, but we really at this point feel like we have stabilized that group and should expect the performance we demonstrated in this current quarter and the margins associated with it. As we mentioned, we did the restructuring last quarter, which will yield us some incremental benefits on our cost line. But on the revenue side we feel good about the revenue generation we had and see no reason why we can't duplicate that.
Mike Walkley - Analyst
Okay, great. And then just last question for me, kind of filling up the model with -- I think you said cellular router and gateway business grew 60%, six zero percent, if I heard that right? That's a great number. But at lower gross margin and then the RF was at the high end of your range of maybe 24% growth for the first half of the year. As they become more of the mix, how should we think about gross margin trends offsetting leverage in the model on higher revenue, but gross margin headwinds on faster-growth, lower-margin products?
Ron Konezny - President, CEO, and Director
Yes, we are trying to get much more aggressively stanced in our larger-volume customers that need us to evolve with their needs. Now, of course, we're not standing still, right? So we're working hard on our cost of goods.
We think we can grow into slightly reduced gross margins that we exhibited this last quarter with a better operating expense profile. And so now -- to be sure, we're not giving up, if you will, on our gross margin pursuit. So we're going to continue to drive efficiencies.
We still some a little bit of residual in this last quarter in terms of our manufacturing recovery, so we had slightly higher costs than maybe we would anticipate on a run rate basis. So long story short, we are fighting on both fronts. We're going to retain these customers at pricing levels that are market-driven, but we're also going to drive down COGS. And hopefully that growth will then put us in a good position, because we won't have to scale OpEx to support that growth.
Mike Walkley - Analyst
Okay, great. Well, congrats on the strong first-quarter results here as a CEO, and best wishes for continued success with all your initiatives.

Howard Smith, First Analysis.
Howard Smith - Analyst
Steve, been a pleasure working with you over the years. I wish you nothing but success. Mike, welcome. And Ron, great first quarter. So it's a nice start.
Ron Konezny - President, CEO, and Director
Thank you, Howard.
Howard Smith - Analyst
Question -- first of all, just kind of a numbers question on guidance. If I am going with the midpoint of guidance for Q3 and the midpoint for the full year, it implies to me there flat or possibly even down top line and maybe flat on the bottom line in your fiscal Q4. And I'm wondering, should I be reading -- is there anything causing a softness seasonally or otherwise? Or is it just -- don't read too much into that?
Ron Konezny - President, CEO, and Director
Yes, I wouldn't read too much into that. Steve mentioned we did get a little bit of a lift in this current quarter from some product that we were unable to ship in the first fiscal quarter. And so -- I wouldn't over-read into the guidance.
Howard Smith - Analyst
Okay. And then on the large customer retention margin trade-off thing, which we have talked about in the past, a little surprised, not just on terms of what you said you're tracking, but at actual current customers. Maybe you can give a little more color. Did you actually, during the quarter, go to some of your existing customers and have discussions around this? It's a little more immediate than I thought. Maybe you could explain a little bit.
Ron Konezny - President, CEO, and Director
As I mentioned, we did have slightly higher cost basis in the last quarter as we were fully recovering from this disruption in Q1. So that certainly had a little bit of an impact.
I wouldn't characterize the margin as being impacted primarily by going to existing customers and having this dialogue as much as it is, I think, a more competitive and aggressive stance in the marketplace. We are very focused on winning. We are very focused on retaining. We've got increased levels of customer engagements -- hand-to-hand combat, if you will.
And I think that's allowing us to have deeper relationships, where we can possibly trade off that slightly lower margins for increased visibility, longer-term commitments. So we are being smart about it. But we are playing to win as well.
Howard Smith - Analyst
All right, appreciate the color. Thanks much.
Operator
(Operator Instructions) I'm showing no further questions. I would like to turn the call back to Mr. Ron Konezny, CEO, for closing remarks.
