Thank you, Dave.
First quarter of 2006 represented our third consecutive quarter of strong operational execution and improving financial metrics, following the restructuring of our business in mid-2005. Our business recovery continues to gain momentum. During the first quarter, we ran production and shipments of our new HSDPA AirCards to customers in North America and Europe. We continued strong shipments of our AirCard 580 for EV-DO networks. We significantly expanded our embedded modules business with several new design wins and growing shipments. We grew revenue by more than 20% over the fourth quarter of 2005, resulting in record first-quarter revenue. We also had strong gross margins, driven by growing volume, product mix, some cost reduction and ASP management. And finally, we achieved a higher-than-expected net profit.
Intense focus on our core business of a wide area wireless for mobile computing is driving this recovery and is strengthening our competitive position in a market which we believe has significant growth opportunities. While we are very pleased with our Q1 results and the strength of our business recovery, we also recognize that continued hard work and strong execution is required before we achieve the goals we have set for ourselves in terms of product line strength, market position and financial results.
Moving to business highlights, I will start with activities in our AirCard business. A significant part of our overall sequential growth revenue growth in the quarter was driven by increasing sales of our AirCard products. Our increased sales of AirCard products was driven mainly by growing sales of our HSDPA AirCards, specifically, the AirCard 860 for North America and the AirCard 850 for Europe. When we launched our HSDPA AirCards in Q4 of 2005, they were the world's first fully functional HSDPA PC cards. Since launch, have rapidly built production capacity for these products in order to meet growing demand. Our AirCard 860 volume in the quarter was driven mainly by Cingular Wireless in the US. We've earned a strong channel position at Cingular for our AirCard 860, and are benefiting from increasing demand for our product, combined with Cingular's Broadband Connect service.
We commenced shipments of our AirCard 850 to several customers across EMEA, including carriers and distributors in Spain, France, Portugal, Italy, Switzerland and South Africa. Although it is still early days for HSDPA in Europe, we are experiencing the benefit of our first to market launch of the AirCard 850. After tripling our revenue in Europe from Q3 to Q4 of 2005, we continued to see strong growth in Q1 of 2006. During the quarter, we grew our revenue in Europe by 50% over Q4, resulting in record revenue for the region. We view our initial traction with the AirCard 850 as an important first step in re-establishing a strong position for ourselves in the European market.
In our EV-DO AirCard business, we continued to have strong sales of the AirCard 580 to Sprint in Q1 and continue to see solid sales of the product in Canada, Australia and New Zealand as well.
Moving to new product development activities in our AirCard and rugged mobile business, development of our next-generation EV-DO Rev. A and HSDPA 3.6 AirCards continues on track. During Q1, we achieved key product development milestones for our AirCard 595 for our EV-DO Rev. A networks ahead of our competition. Together with Lucent and Nortel, we achieved the industry's first over-the-air Rev. A calls using a precommercial yet form factor-compliant version of the AirCard 595. These early interoperability tests with leading infrastructure providers represents an important step in bringing a solid, high-performance product into the market ahead of other manufacturers.
We also did extensive live demonstrations of the AirCard 595 with Lucent, Nortel and Sprint at the CTIA Wireless trade show in early April, achieving impressive data transfer rates on both the downlink and uplink channels. The AirCard 595 is now available to operators and other customers for testing and integration purposes. We anticipate that the AirCard 595 will be commercially available in the third quarter of 2006.
Development of our next-generation HSDPA AirCard, the AirCard 875, is also on track for launch in the second half of 2006. The AirCard 875 will offer peak data rates of 3.6 Mbps and will also support Tri-band HSDPA as well as Quad-band operation on EDGE and GPRS networks. The AirCard 875 will be a truly global wireless broadband communications device. We view the AirCard 875 as another important product for further strengthening our position in the US market and for continuing to grow our business in Europe.
Our AirCard 875 is now making live, over-the-air calls in our development labs.
Additionally, we have projects under way to bring next-generation versions of our rugged mobile products to market. Our MP products have a loyal customer base in the public safety and field service segments and are an important contributor of gross margin. We expect to launch two next-generation versions of the MP, 1 for EV-DO Rev. A and 1 for 3.6 HSDPA, later this year and early next year.
Moving to highlights in our OEM business, sales of our embedded module products grew once again in Q1 and contributed a growing percentage of our overall revenue mix. The growth in our OEM business was driven primarily by increased sales of our legacy embedded module products to our traditional OEM customer base. Sales of our new EV-DO Mini Card embedded module to laptop OEMs were flat in Q1 relative to Q4 of 2005. We view our Q1 sales in this segment as consistent with the nascent stage of this new and potentially high-growth market.
During Q1, there were several industry developments, announcements and promotions in the embedded-for-laptop space, which indicate to us that moment is building. In our own business, we made significant progress on design wins, OEM platform expansion and product development that we believe will be important growth catalysts for our business. We remain bullish yet patient on the embedded-for-laptop sector and believe that we are well positioned to capture a leading share in this potentially high-growth market. We have design wins with Lenovo, HP and Panasonic for our EV-DO modules and commenced commercial shipments of these products in the second half of 2005. Our fourth quarter launch with Lenovo represented the first commercial deployment of an embedded 3G wireless Mini Card by any laptop manufacturer, making us and Lenovo first to market.
Early in Q1, HP also announced the availability of their first laptop platform, incorporating our EV-DO Mini Card. Since announcing these initial design wins, Lenovo, HP and Panasonic have all incorporated our EV-DO embedded module solutions into multiple laptop platforms. As these new platforms launch, the addressable market for our embedded module products grows considerably.
Since our first-to-market EV-DO Mini Card launch, we have announced design wins with both Lenovo and Fujitsu Siemens for our MC8755 Mini Card for European UMTS HSDPA networks. We've completed development of the MC8755 on schedule and commenced initial commercial shipments of the product during the first quarter.
During the first quarter, we were also awarded an additional HSDPA design win with a major laptop OEM. We also secured several new design wins with manufacturers of fixed wireless terminals for both our EV-DO and HSDPA embedded modules. We are encouraged by our early success in the fixed wireless terminal segment and believe that this space, like laptop market, could be an important growth contributor to our business.
Moving to new OEM product initiatives, as mentioned, the development of our MC8755 Mini Card module for European HSDPA networks is now complete, and production is ramping. Our MC8765 for North American HSDPA networks is nearing completion. We expect to launch the product during the current quarter. We have OEM design wins for both of these products.
Development of our next-generation Mini Card modules for EV-DO Rev. A and HSDPA 3.6 are also on track. We expect to launch both of these next-generation products in the second half of 2006.
During the first quarter, we announced that our new MC5725 EV-DO Rev. A Mini Card module is now available to OEMs, infrastructure partners and carriers for integration and testing purposes. As we achieved with the AirCard 595, we performed the industry's first over-the-air Rev. A calls using precommercial versions of the MC5725 with both Lucent and Nortel. These interoperability tests with leading infrastructure providers represents an important step in bringing solid, high-performance product into the market ahead of other manufacturers. We also did extensive live demonstrations of the MC5725 with HP, Lenovo, Panasonic, Lucent, Nortel and Sprint at the CTIA Wireless trade show event in early April. I believe these early demonstrations and integrations highlight our strong R&D execution in Rev. A.
Moving to some more general comments about the state of our business, our channels reported strong sell-through of our products in Q1, highlighting growing market demand. Bookings in Q1 were also strong, as they were in Q4, giving us good visibility to Q2 2006 revenue. We were also able to strengthen our inventory position during the quarter on select products, putting us in a better position to respond quickly to increases in customer demand. And during the quarter, we witnessed continued aggressive deployment of high-speed 3G services by many of the world's leading operators. We view this deployment, coupled with the associated promotional activities related to high-speed wireless data, as an important catalyst for our business. We believe this trend will continue throughout 2006 and beyond.
I will now turn it back over to Dave to cover our Q1 financial results.
Dave McLennan - CFO
Thanks, Jason. Looking at our first quarter 2006 results, our results are recorded in US dollars and are in accordance with US GAAP.
For the first quarter of 2006, our revenue was 45.2 million, gross margin was 16.7 million, or 36.8%; operating expenses were 14.8 million, and our net income was 2.6 million, or $0.10 a share. During the quarter, Cingular and Verizon each accounted for more than 10% of our revenue. And in aggregate, these two customers represented approximately 38% of our revenue.
As a result of adopting new accounting standards for stock-based compensation, our first quarter results include a non-cash stock-based compensation expense of $900,000. Prior to 2006, the impact of stock-based compensation was not reflected in our income statement. Because this is new and to assist you in understanding the impact of stock-based compensation expense on the various components of our cost structure, the Q1 results as reported in the financial statements presented in our press release include stock-based compensation as follows -- in cost of goods sold, approximately $90,000; in sales and marketing, approximately 275,000; R&D, 170,000; and administration, approximately 350,000.
Looking at our results for the first quarter of '06 relative to the guidance we provided on January 26 for the quarter, fourth quarter revenue was 45.2 million, approximately 13% better than our guidance of $40 million.
Right, so Q1 revenue was 45.2 million, approximately 13% better than our guidance of $40 million. Gross margin was 36.8%, above our guidance of 33.5%. Operating expenses, excluding stock-based compensation expense, were 14 million, in line with our guidance of 13.7 million. Operating expenses, including stock-based compensation expense, were 14.8 million, in line with our guidance of 14.7 million. Net income of 2.6 million, or $0.10 per share, was better than our guidance of a net loss of $800,000, or a loss per share of $0.03. Excluding stock-based compensation, our net income of 3.5 million, or $0.13 per share, was better than our guidance of breakeven to slightly positive earnings. Our free cash flow, being cash flow from operations, less CapEx for fixed assets and intangibles, was negative 2.2 million, consistent with our guidance of negative cash flow.
Contributing to the negative cash flow in Q1 was a royalty payment of 5 million to an intellectual property holder for historical sales. The royalty payment was made as per an agreement entered into in December 2005. The expense related to these royalties was accrued for in prior periods.
Looking at our Q1 '06 results compared sequentially to Q4 2005, revenue increased to 45.2 million from 37.6 million, an increase of 20%. This growth primarily came from the sales of our new HSDPA PC cards in North America and Europe. EV-DO and EDGE PC cards were fairly consistent quarter on quarter.
Overall OEM sales were up during the quarter, driven by sales of our legacy embedded module products to our traditional OEM customer base. Sales of Mini Card embedded modules to laptop OEMs were flat in Q1 versus Q4, consistent with the nascent stage of this product category.
In terms of gross margin, gross margin was 36.8% in Q1 compared to 38.6% in Q4. Recall that Q4 gross margin included a 3.2% favorable impact from the finalization of our royalty agreement, the cost of which had been accrued for at higher rates in prior periods. Q1 gross margin showed improvement over the normalized Q4 gross margin, driven by growing volume, product mix, ASP management and some product cost reductions.
Looking at OpEx in Q1 versus the fourth quarter, for the purposes of comparison, if we exclude stock-based compensation expense, our operating expenses were 14 million in Q1 versus 14.6 million in Q4. Most of the sequential decline is due to a drop in sales and marketing costs as Q4 was a heavy new product launch quarter.
And finally, net earnings, again for the purposes of comparison excluding stock-based compensation expense, net earnings were 3.5 million, or $0.13 per share in Q1 versus earnings in Q4 of 900,000, or $0.04 per share, reflecting the impact of higher revenue, continued strong gross margin and good OpEx management.
Moving to the balance sheet, compared to December 31, 2005, our cash, short and long-term investments decreased by 2.4 million to 101.7 million at the end of Q1. This decrease in cash reflects the improvement in our operations less the 5 million royalty payment referred to earlier. Inventory levels increased during the quarter from 3.3 million to 11.2 million, as we were able to build inventory positions on select products in order to be able to quickly respond to increasing customer demand. We expect to continue to strengthen our inventory position in Q2.
Looking at our revenues by product line, PC cards represented 72%, or 32.3 million, of our revenues in Q1, compared to 68%, or 25.5 million, in Q4. Our OEM business represented 18%, or 7.9 million in Q1, compared to 17%, or $6.5 million in Q4. Our MP business was 8%, or $3.8 million in Q1, compared to 9%, or 3.4% in Q4. And Other was 2% in Q1 versus 6% in Q4.
The growth in our PC Card revenue during the quarter was driven primarily by increased sales of our new HSDPA AirCards to customers in the US and Europe. OEM sales were up during the quarter, driven by sales of legacy embedded module products to our traditional OEM customer base.
Looking at revenues by distribution channel, carriers were 51% in Q1 versus 51 in Q4, resellers were 30% in Q1 versus 31% in Q4, OEM was 19% in Q1 versus 18% in Q4.
Looking at revenues by technology, GSM-based revenues, which include EDGE and HSDPA, were 49% in Q1 versus 47% in Q4. CDMA was 49% as well in Q1 versus 50% in Q4, and Other was 2% in Q1 versus 3% in Q4. During Q1, sales of HSDPA AirCards added significantly to our GSM-based business. We also experienced solid growth in our CDMA revenue, driven by increased sales of rugged mobiles and embedded module products.
And finally, revenue by geography. In Q1, revenue in the Americas was 69%, or $31.2 million, versus 67%, or 25.3 million in Q4. Revenues in Europe were 18%, or $8 million in Q1, compared to 14%, or $5.2 million in Q4. In Asia-Pacific, revenues were 7%, or $3.3 million in Q1, versus 12%, or 4.4 million in Q4. And in our worldwide PC OEM segment, revenues were 6%, or $2.8 million in Q1, versus 7%, or 2.7 million in Q4. We had strong growth in the Americas in Q1, driven primarily by increased sales of our AirCard 860 [for] HSDPA to Cingular in the US in support of their nationwide Broadband Connect rollout.
In Europe, we saw growth in Q1 '06 of 50% over Q4 '05, reflecting our initial traction with the AirCard 850. Asia-Pac sales declined modestly, and the worldwide PC OEM sales were relatively flat, reflecting the nascent stage of this market.
Onto guidance for the second quarter of 2006. We are providing guidance for the second quarter ending June 30, 2006, which reflects our current business indicators and expectations. Inherent in this guidance are risk factors that are described in detail in our regulatory filings. Our actual results could differ materially from the guidance presented. Our guidance for the quarter includes a significant contribution from recently launched products. There are uncertainties associated with the launch and early ramp of new products that could affect our ability to achieve this guidance. All figures are estimates based on management's current beliefs and assumptions and are subject to change.
We expect Q2 to show continued sequential revenue growth over the first quarter. Our guidance for Q2 revenue is $52 million. Gross margin guidance is 34.5%. Operating expense guidance is $16 million, and that results in a net income of 2.6, or $0.10 a share. This guidance includes stock-based compensation expense of approximately $1 million.
Expected increase in OpEx relative to Q1 reflects third-party certification costs in advance of new product launches scheduled for the second half, as well as some measured investments in new products and infrastructure to strengthen our core position and drive growth. Additionally, in Q2, we expect cash flow to be slightly negative to slightly positive, depending on the level of our ending inventory.
With that, I would like to turn it back to Jason for a summary.
Jason Cohenour - President, CEO
Thanks, Dave. During the first quarter of 2006, we saw continued improvement in the financial metrics of our business and continued strong execution on new product development, production ramp and sales. Revenue for the first quarter was up 20% compared to the fourth quarter, driven by growing sales of our HSDPA AirCards and CDMA embedded modules. Gross margin was strong in the quarter, and we managed operating expenses effectively. All of these factors contributed to a better-than-expected net income result.
We expanded the customer base of our HSDPA cards, particularly in Europe, where we experienced 50% sequential growth and had record revenue. We saw good growth in our traditional embedded modules business and continue to execute well in the emerging embedded module for laptop space. The strength of our execution is highlighted by the commencement of commercial shipments of our first HSDPA Mini Card and by securing a third design win with a major laptop OEM for HSDPA Mini Cards.
We showcased our strong development progress in EV-DO Rev. A, achieving the industry's first live Rev. A calls with precommercial devices and by demonstrating both our AirCard 595 and MC5725 with an impressive roster of industry leaders at the CTIA show in early April.
Development continues on track for our next-generation HSDPA AirCard and Mini Card products as well, and we expect to commence commercial shipments of these products in the second half of the year. Our focus for the balance of 2006 is to continue to execute on our new product pipeline and the business development activities related to bringing these new products to market, as it is these activities that are providing the foundation to our strong recovery.
While execution on our current programs is our first priority, we're also focused on making select additional investments in new product development and support infrastructure to strengthen our position in wide area wireless for mobile computing. We believe that the market for wide area wireless for mobile computing will continue to grow at a healthy pace and that continued strong execution and careful reinvestment will enable us to capture a growing share of this growing market. Given the robust industry demand outlook and our continued strong execution on new product development and the related sales, marketing and production activities, we anticipate further growth in our business in Q2, and in the second half of 2006 as well.
While our second half outlook is bullish, it is still too early to illustrate for you the shape of our growth curve, given several factors that need to play out, such as precise timing on product launches, technology transitions, new OEM platform launches and seasonality.
While we're very pleased with our Q1 results and the strength of our business recovery, we also recognize that a lot of hard work and continued strong execution is required before we achieve the goals we have set for ourselves in terms of product line strength, market position and financial results.
And with that, I will open the line up for questions.
Operator
(OPERATOR INSTRUCTIONS). Deepak Chopra, National Bank Financial.
Deepak Chopra - Analyst
Great quarter, guys. I was wondering if you could talk a little bit about the trend line you saw in the quarter in terms of ordering pattern. Did you have a book-to-bill ratio of better than 1? And also, if you could maybe comment on inventory that you're seeing in your different respective channels?
Jason Cohenour - President, CEO
Well, I'll give you a directional commentary on bookings, and I mentioned it already. And what we don't do typically, Deepak, is provide book-to-bill ratios. But we did mention that bookings were strong in the quarter, and -- as they were strong in Q4 as well. And those two strong bookings quarters in a row gives us good visibility on Q2 revenue.
With respect to channel inventory, again, a kind of directional commentary for you. Our channels reported strong sell-through during the quarter, very strong sell-through, in fact. So we're comfortable with the channel inventory levels.
Deepak Chopra - Analyst
Did you struggle meeting demand during the period?
Jason Cohenour - President, CEO
Well, we were in a better position in Q1 to meet demand than we were in Q4 and Q3.
Deepak Chopra - Analyst
Fair enough. Maybe just one last quick question. In terms of pricing pressure on the HSDPA side, are you seeing anything there right now relative to what's typically normal? Has it become more aggressive, the environment; or, is it following patterns you have seen over the last two quarters?
Jason Cohenour - President, CEO
It's aggressive. I don't know if it's any more intense, Deepak, but it's definitely aggressive, particularly in Europe, where incumbent players are defending their turf aggressively. And that's anticipated. And frankly, in order to crack that market and continue growth in that market, we need to be aggressive on pricing as well.
Deepak Chopra - Analyst
Thank you, great quarter.
Operator
John Bucher, Harris Nesbitt.
John Bucher - Analyst
Thank you very much. I think you all indicated that the OEM module for the Rev. A and HSDPA were relatively flat, fourth quarter to first quarter. I'm wondering, do you think that the looming availability of your Rev. A and 3.6 HSDPA might be overhanging decisions to incorporate those modules in large orders?
Jason Cohenour - President, CEO
I honestly don't think so, John. And first, to clarify, during the quarter, we really were only shipping the EV-DO Mini Card in any meaningful volume. Our HSDPA Mini Card was -- we had initial commercial shipments; they were quite modest in the quarter. So I think lots leads up to a design win and an integration effort; and, candidly, once the train kind of leaves the station on commencement of integration work and go-to-market planning, it's awfully hard to stop that, right? So the fact that we had a product roadmap -- which, by the way, our OEM customers have seen for quite some time -- that headed Rev. A and 3.6 HSDPA devices on it -- I don't think that's playing into their decision with respect to Rev. 0 and what, when 1.8 launches.
In fact, we have seen just the opposite. We have had additional design wins in the first quarter for our Rev. 0 and 1.8 products, and in addition to that, some of our existing laptops have now expanded those modules to more of their platforms. And we see the results of that expanded platform activity as well. Those new platforms are just now getting completed and certified and getting ready for launch.
John Bucher - Analyst
Even though we're almost at mid-year and you're going to be launching the Rev. A and 3.6 HSDPA in the second half, you don't think that's having a significant impact on people's decisions to move forward?
Jason Cohenour - President, CEO
[It's too late]. All of the decisions related to embedding wide area wireless inside a platform have been made months ago.
John Bucher - Analyst
I'm speaking more not in terms of the OEM manufacturers, but rather some of the enterprise decision makers and buyers who would be procuring this equipment.
Jason Cohenour - President, CEO
Oh, I see, I see -- the [end-users]?
John Bucher - Analyst
Yes, sir.
Jason Cohenour - President, CEO
You know, I don't know. You could ask the same question about AirCard sales, right? There's always something new and faster coming down the pipe -- same with notebooks. So that's always a factor, John. I don't think that's a factor in our flat quarter-over-quarter sales, though, our flat sequential sales. I think the bigger factor there is just, it's early.
John Bucher - Analyst
Point taken. Were there any component scarcities or any supply chain limitations where you are having to order significantly? And I noticed your inventories did come up a bit, and you indicated that next quarter, we should expect them to come up a little bit more, too. Are there certain long lead items? And if you can say what they are?
Jason Cohenour - President, CEO
Well, we would prefer not to comment on what they are. But, there are a number of them that are long lead and difficult to get. So it's a -- worldwide demand for wireless products is very high and increasing, as you've seen from announcements by QUALCOMM, Nokia and others. And that does put pressure on supply chain. And we have been aggressive -- and we saw that coming, too. So we have been aggressive on supply chain now for six to nine months, knowing that worldwide demand was increasing and the supply chains was tightening on myriad components; not just one, two or three components.
So we're purchasing farther ahead against both demand and new product launches. We're actually purchasing components now much earlier in the new product development cycle so that we're ready at launch. And we have to do that, given the strength of worldwide demand for wireless components.
John Bucher - Analyst
You have the balance sheet for it, anyway. Final question -- with respect to Verizon Wireless, they were mentioned as a greater than 10% customer. I'm guessing that that must have been traditional embedded modules that were going to Verizon?
Jason Cohenour - President, CEO
No; we don't sell embedded modules to Verizon, so -- or any operator, for that matter. Or if we do, it would be very unusual. So what we sell to operator customers are our finished products. So during the quarter with Verizon, we did have sales of AirCard 580s; I would characterize that as modest. And we had robust sales of our MP products to Verizon.
John Bucher - Analyst
Okay, congratulations on a profitable quarter.
Operator
Andrew Lee, TD Newcrest.
Andrew Lee - Analyst
Jason, the comment on the HSDPA design win -- did you comment whether it was North American or Europe for the embedded module?
Jason Cohenour - President, CEO
No, I didn't.
Andrew Lee - Analyst
Okay. And have any of the OEMs gone to dual sourcing yet to your knowledge?
Jason Cohenour - President, CEO
Yes, Panasonic has.
Andrew Lee - Analyst
Right; but have the tier ones, any of them gone?
Jason Cohenour - President, CEO
I don't believe so.
Andrew Lee - Analyst
So this is the first time, to my knowledge, you guys have actually disclosed the Mini PC Card -- Mini PC, sorry, --revenues. Are you going to do that on a go-forward basis?
Jason Cohenour - President, CEO
We are. We've made -- we and, frankly, some of our competitors -- have made lots of noise around it, and we believe it's a strategic initiative for us and operators and OEMs, and it's certainly important enough that we spotlight it and give you guys and information because we're making significant investments in that area.
Andrew Lee - Analyst
And so the growth in the OEMs -- you said more on the legacy side. What were the applications they were going into?
Jason Cohenour - President, CEO
On the legacy side?
Andrew Lee - Analyst
Yes.
Jason Cohenour - President, CEO
A basket of applications, a lot of it mobile computing-oriented, but also a lot of it vehicular-based systems for vehicle tracking and dispatch and the like, as well.
Andrew Lee - Analyst
Novatel has made some comments with regards to express card development. You guys have not talked about that. Is that something on your roadmap?
Jason Cohenour - President, CEO
It is on our roadmap. We have not disclosed specific timing for product launch for competitive reasons.
Andrew Lee - Analyst
How do you view that opportunity? When would notebooks start offering that slot in addition to the Type II slot?
Jason Cohenour - President, CEO
Well, they already are. It's very nascent, but there are a handful of platforms that are in the market today that have both express card slots and PCMCIA slots. I believe Dell has a platform that actually has a -- has only express card slots targeted at consumers, primarily. So our view is, there's going to be a significant overlap period here where both slots are in existence in the market. And over time, there's going to be a slow transition over to express card only. But our view is, it's going to start with consumer platforms, and in most cases, it's going to start with both slots in a given platform, and then, over time, migrate over to all express card. But that migration, in our view, will take years.

Dave, just on taxes, how do we think of the tax rate for the rest of this year and for next year?
Dave McLennan - CFO
In terms of 2006, you saw that we did book a tax expense. It's a non-cash tax expense in this quarter. And I would use a range of 15 to 20% throughout this year -- would be a range to model it around.
Andrew Lee - Analyst
And does that drop next year or go up next year?
Dave McLennan - CFO
I would expect that to increase next year, and we need to put in some management strategies. But I think longer term, a target would be approximately 25%.

Mike Abramsky, RBC Capital Markets.
Mike Abramsky - Analyst
Congratulations on a really great quarter and good guidance. Could you give us a bit of insight into, to the extent that -- I realize you don't break this down, but Sprint was a 10% customer last quarter. They are not this quarter. And you just discussed shipping robust MP to Verizon. So it really sounds like the lion's share of your card momentum is going to [roll it] at Cingular. And is that a fair assessment of what's going on?
Jason Cohenour - President, CEO
No, I wouldn't characterize it that way. I think it's fair to characterize that our growth in the quarter was driven by HSDPA, largely, and Cingular and in Europe. But we continue to have strong, consistent sales of our EV-DO AirCard as well during the quarter. And I think that bears out in our technology breakdown as well. You can back into the math; it was fairly consistent and strong. And that goes for Sprint as well. Now, they weren't a 10% customer in the quarter, but revenue was up 20% as well. So they were still big and important.
Mike Abramsky - Analyst
And built into your guidance is -- do you see this similar sort of aggregate Cingular/Verizon share coming in Q1 -- sorry -- in the next quarter?
Jason Cohenour - President, CEO
Well, we don't give specific guidance per customer, but we do anticipate -- directionally, we anticipate strong sales continuing into Cingular. We anticipate strong sales continuing into Sprint, and we anticipate some further traction in Europe, as well as expansion in our embedded modules business.
Mike Abramsky - Analyst
And you discussed earlier that pricing is aggressive, particularly in Europe. Is there going to be -- what's your strategy on preserving margins over market share penetrations for Europe? And may we see that come into your European margins as a whole, if you chose to make a big push there?
Jason Cohenour - President, CEO
Well, there's not a lot of magic here, candidly. We need to continue to be aggressive on cost reduction; that's one key area of bolstering gross margins. But of course, cost reduction takes time; you can't do that overnight. A salesman with a stroke of his pen can cut out a lot of gross margin, and it takes you a year to get that back in cost reductions. So we continue to do basic, strong blocking and tackling on cost reduction; that's going to be key. And over time, we're going to be adding differentiation to our product lineup as well. And we're not going to disclose exactly how that is going to come in, whether or not there's tiers of product or we just add differentiation to a single product and charge more for it. But we believe that we need differentiation, and we also believe that we need a portfolio effect in our product line, which is probably too narrow today to have that portfolio effect, that will enable us to, over time, blend gross margins to a strong level.
And notice I fell short of saying -- blend gross margins up -- blend them to a strong level. And we've said it repeatedly in the past. While our gross margins have been very strong the last couple of quarters, we have got pretty solid gross margin guidance, our longer-term view of our business is, even with a portfolio effect, is that our gross margins will be in the low 30s as volume goes up. And that's just the business we're in.
Mike Abramsky - Analyst
So you're sort of implying that this diversified portfolio will give you more market penetration [rapport] and more kind of bullets in the gun, in regard to that, but at the expense to some extent of perhaps some of the gross margin strength you have now; but you will still be within your guided range?
Jason Cohenour - President, CEO
I guess that's a fair characterization.
Dave McLennan - CFO
A bending portfolio approach.
Jason Cohenour - President, CEO
Yes.
Mike Abramsky - Analyst
Do you see in the big picture that the advance speeds of Rev. A are going to drive the same demand curve as what EV-DO is driving now? I mean, EV-DO is still relatively an early technology, as far as deployment is concerned, adoption.
Jason Cohenour - President, CEO
Our EV-DO PC Card has been in the market for about three years now, so we don't consider it very new, by the way.
Mike Abramsky - Analyst
For you guys, yes. I just meant for the average consumer.
Jason Cohenour - President, CEO
I think it will. Speed drives adoption, for sure. We have learned that over and over, across many generations of technology. By the way, we have yet to see what HSDPA speeds are going to drive in Europe in terms of increased adoption; that's going to play out. We anticipate speed is going to grow the market there, just like it has a North American.
And I think Rev. A is a really important technology, we believe. Well, it's important to us because, well, we have a three-year-old EV-DO card in the market right now. So whether or not it has Rev. A in it, which our AirCard 595 does, it also gives us an updated platform, a little bit more flexibility with respect to driving cost out. So even as a Rev. 0 card, it's important in our product lineup. But on top of that, we do a view Rev. A as an important technology that we hope will drive further adoption. Now, we have no idea what percentage growth that's going to drive, candidly. But it's a pretty compelling speed increase on the uplink, in particular, and that does open the door for myriad new applications that just aren't possible with Rev. 0. And you'll have a similar situation, of course, sometime next year when HSUPA gets deployed by the leading GSM guys.
Mike Abramsky - Analyst
We're going to run out of letter soon.
Jason Cohenour - President, CEO
I know. We'll add dashes, Mike.
Mike Abramsky - Analyst
Last question. Is there an efficiency limit that you're going to reach with regard to some of your cost-cutting measures? Do you see more room there? What's the next kind of phase-in driving improved profitability, or is it really topline at the next point?
Jason Cohenour - President, CEO
Topline, it's all about topline. In fact, we dropped a little hint there; we have raised OpEx guidance in Q2. And true, most of that, better than half of that, is driven by third-party [SERC] costs that are relatively non-recurring, related to new product launches. But the remainder of that is careful reinvestment in our business. And our view is, this market is growing strong now, it's poised for continued strong growth, and A, we cannot afford product holes; and B, we want to blend in that product portfolio effect that we were just talking about a minute ago. And that takes some careful reinvestment, and we believe that's going to drive a significant change in scale.
Operator
Jeff Kvaal, Lehman Brothers.
Jeff Kvaal - Analyst
I wanted to sort of investigate your outlook for the June quarter in a little bit more detail. It seems revenue is up quite a bit, but it sounds like you are looking for the margins to come down a chunk. I'm wondering if that is an ASP phenomenon or a mix shift? And if it's a mix shift back to OEM, is that based on module sales or more legacy products?
Jason Cohenour - President, CEO
It is going to be a combination, we believe, of mix and a steadily increasing shift in our OEM business, growing our OEM business. And also, we're enjoying some decent margins on some legacy products that we would expect to diminish over time as well. So you'll see some movement within the product categories as well. So it's really a function of both pricing and mix.
Jeff Kvaal - Analyst
And if the mix shifts back to OEM, that would presumably be for the PC modules, rather than for legacy products? Is that the way we should think about that?
Dave McLennan - CFO
I think it would be a combination of both, Jeff. Our legacy products are doing well in the OEM segment and we have expectations of increasing with many cards, (technical difficulty) OEMs.
Jason Cohenour - President, CEO
But I do think, in terms of growth rate, Jeff, you should look at -- certainly, our expectations are that the growth rate of Mini Cards inside laptops will be significantly higher than the growth rate related to our legacy embedded modules business.
Jeff Kvaal - Analyst
Okay, so we should see a resumption in the growth rate of those products after a sort of flattish first quarter?
Jason Cohenour - President, CEO
Well, on timing (multiple speakers) --
Dave McLennan - CFO
-- some timing here.
Jason Cohenour - President, CEO
Exactly. So if it doesn't happen in this quarter in a big way, we would certainly expect it would happen in the future.
Jeff Kvaal - Analyst
That, I guess, makes sense. Could you talk a little bit about where you would like your inventory to be in terms of a days number or an absolute number? And certainly, it seems like it was up a chunk this quarter, and I wanted to take a look at where you would like to run that, because I know components are tight, too.
Dave McLennan - CFO
It would be nice to get it into the one to two-month range of inventory. We're very much focused on getting key components, so very targeted by certain key components. But I think if we can drive inventory to a target of a few months or less, that would be (indiscernible) targeting for.
Jason Cohenour - President, CEO
There is a bit of a -- there's a bit of an overperformance goal there, if you will, Jeff, with respect to inventory, because you know that we have in past quarters struggled sometimes to meet customer demand. And sometimes -- well, usually, that customer demand is just not forecasted that well by the customer or by our sales guys. So we need to be in a stronger responsive position in anticipation of those spikes in demand.
Jeff Kvaal - Analyst
It seems (indiscernible) like in the Cingular channel, the [option] card debuted at a bit of a premium to where you and Novatel were pricing priced. But that premium seems to have disappeared over the past couple weeks. I'm wondering if there's anything going on, if we should read into that at all in terms of shared dynamics or which card is featured at that moment?
Jason Cohenour - President, CEO
Well, we stated qualitatively, Jeff, that we feel like we've got a very strong position in the Cingular channel, and they represent a significant part of our Q2 guidance, which is pretty good.
Jeff Kvaal - Analyst
Indeed. Are you in the situation where there is more demand that you might have met, had Cingular -- had components been easier to obtain?
Jason Cohenour - President, CEO
You know, I'd rather not comment on that at any specific level, Jeff. I think that you will find that -- I think you'll find that Cingular has been satisfied with our ability to respond to their demand.

Dev Bhangui - Analyst
Good afternoon, guys, and congratulations Jason as well as Dave and the team, for a quarter exceeding all expectations.
My question was in terms of Europe. I guess, since the European sales have been ramping up, and obviously they are ramping up on the PC card side, you guys have been shipping to some of the carriers in Europe, and those names have not yet been announced; right?
Jason Cohenour - President, CEO
Correct.
Dev Bhangui - Analyst
Would they be classified as major carriers?
Jason Cohenour - President, CEO
I would classify them as important carriers to us. I'm sorry; I'm not trying to be cute there (MULTIPLE SPEAKERS) gotta be careful with disclosure there.
Dev Bhangui - Analyst
Sure. And I guess, in terms of -- okay, I guess just backing up in terms of North America itself, for the Cingular or any other carrier as they kind of move on HSDPA from the 1.8 to 3.6 transition, what is the usual life that you expect, based on what you see right now?
Jason Cohenour - President, CEO
Then usual life in the 1.8 card, you mean?
Dev Bhangui - Analyst
Yes, I understand -- carrier, whether it's in Europe or in North America, will shift from the current 1.8 to 3.6, and will start demanding from you as well as your competitors the 3.6 version. What is the usual timeframe that you expect?
Jason Cohenour - President, CEO
There is -- I will look back in history and give you my answer. And by the way, that's, as you guys like to say, it's no guarantee of future performance. But there is usually -- in all of our products, there's a longer tail on the older thing we ever anticipate.
To give you an example -- we are still selling 1X PC cards. We are about out of them, but, believe it or not, we are still selling 1X PC cards. And who would have thought that three-plus years after we launched our EV-DO card, we would still be selling 1X PC cards? But we are. And the same goes for EDGE, by the way; we're still selling EDGE PC cards, by the way, to Cingular as well. So we always go into these technology transitions believing that there's a cliff on the old thing -- man falls off a cliff. And in reality, what generally happens is, there's a longer tail that you expect.
Dev Bhangui - Analyst
I guess I was just kind of flip-flopping between Europe and this question. In terms of the Q2 guidance and going forward, obviously the ramp in terms of the Q2 guidance over the Q1 guidance -- I would still say that the European sales of PC cards will have not yet been factored. Would that characterization qualitatively be right?
Jason Cohenour - President, CEO
You mean -- if I read into your question, are you saying that you think in our guidance, European sales are flat?
Dev Bhangui - Analyst
No. I'm saying that the European wave, if at all we can expect a European, I guess, wave in terms of revenue growth for Sierra Wireless -- that is yet to come in terms of the guidance that we see in Q2?
Jason Cohenour - President, CEO
Oh, in terms of rapid growth?
Dev Bhangui - Analyst
Yes.
Jason Cohenour - President, CEO
Yes, I think that's safe to say.
Dev Bhangui - Analyst
Just moving on to the OEM channels, the new round of OEM wins -- and I guess everybody is kind of working on that right now --
Jason Cohenour - President, CEO
Dev?
Dev Bhangui - Analyst
Yes?
Jason Cohenour - President, CEO
Just a little more color on the European commentary. Part of that is, it's kind of a weird environment there now where you don't have a lot of HSDPA networks up and operating; right? And the ones that are, are with smaller carriers. So it's kind of a bit of a strange technology transition no man's land, and that, of course, has a dampening effect on demand. Notwithstanding our performance, it has a dampening on demand.
I think, once HSDPA networks get fully deployed by the major groups and high-speed is actually available to European customers, that will have a positive impact on demand overall. And we are clearly hopeful that we will be a beneficiary of that demand growth.
Dev Bhangui - Analyst
In terms of the OEM wins itself, I guess I wanted to find out whether the second round of OEM wins -- is that going to be on the EV-DO Rev. A and the 3.6 HSDPA platforms, respectively? Or, is it still on the previous one? And what is going to be the timing of this particular round? Not in terms of announcements, in terms that you guys really enjoying the revenues out of those -- out of round wins?
Jason Cohenour - President, CEO
Out of round two?
Dev Bhangui - Analyst
Yes.
Jason Cohenour - President, CEO
That's a 2007 thing for us in terms of actual revenue, I think.
Dev Bhangui - Analyst
Early, or mid?
Jason Cohenour - President, CEO
That's about as far as I'll go on that, Development, because candidly, my crystal ball doesn't go that far out. There is a laptop cadence, though. New -- laptop OEMs tend to launch new OEM -- new laptop platforms roughly once a year. Often that's at the start of the year. Sometimes late in the previous year, there's a modest refresh. But generally speaking, there's a target of late in the year or early in the following year for new platform launches. And that's the most convenient time to upgrade your air link capability, as well. So for our next generation sales, Rev. A and 3.6 HSDPA, it's more of a late 2006 and into '07 sort of phenomenon.
Dev Bhangui - Analyst
Quick question to Dave, I guess. Dave, and I think Jason also in your (indiscernible) commentary, you guys mentioned about cost reductions and ASP management. Can you give us a little bit more color in terms of that and whether that's going to be like a short-term, one or two quarters, phenomenon or is it going to be a long-term phenomenon?
Dave McLennan - CFO
In terms of product cost, Dev?
Dev Bhangui - Analyst
Yes.
Dave McLennan - CFO
With respect to product cost, Dev, it's what typically happens is, you begin negotiating major product cost reductions, component reductions, manufacturer value-add reductions. You tend to do that as the year winds down, and often they are implemented at the start of a new year. And if you have lots of inventory, then it takes a while for those product cost reductions to kind of flow through and for you to get the benefit of it. That didn't happen to us this year, right, because we had -- we were in the weak inventory position at the start of the year and we were able to, based on forward-looking demand trends, able to negotiate pretty good cost reductions. So, we had an immediate impact of those cost reductions in the first quarter.
And so what happens between now and the end of the year? It's more modest grinding, is the way I would characterize it, Dev. Usually, you have a little step function at the start of the year and you're able to ground down modestly on that over the course of the year.
And then with respect to ASPs, that's going to move around a little bit, frankly. The more revenue we get from big, major, high-volume channels, the more ASP pressure we're going to have. And the more we get volume from smaller channels where we get better ASPs, the better our blended ASP is going to be. And that moves around quarter to quarter.
And we have time for one more question, Operator.
Operator
Sera Kim, Raymond James.
Sera Kim - Analyst
I'm wondering just in general terms, do you expect -- when do your design wins for newer network technologies take place? So, like if you have EV-DO Rev. A products that are ready to be commercially shipped in Q3 that are going through the [interop] and integration testing right now, is the design win actually for Rev. A happening now? Or, do you expect that to happen once it's commercially available?
Jason Cohenour - President, CEO
Well, we're certainly always working on new design wins for existing and next-generation platforms. And so that's kind of an ongoing thing; you can't pinpoint whether or not that has just started now or last week, or it's going to start next week. It's kind of a -- it's a constant thing.
Sera Kim - Analyst
So, just so that I understand, it happens while you're developing the product, or while the product is near completion?
Jason Cohenour - President, CEO
It's happening many times, even before you start developing. So it does vary a bit, but part of winning an OEM, getting a design win and winning an OEM relationship, is roadmap. And some of the things on your roadmap, you don't have an engineering team on it yet, but you know that you're going to commence it at a certain time and release it at a certain time, and that becomes part of the overall relationship discussion in actually winning that customer.
Sera Kim - Analyst
And for design wins, how easy or difficult do you think it will be to displace competition, your competition, from other OEMs, I guess with future platforms? Because you mentioned that every year there's opportunity to replace the air link.
Jason Cohenour - President, CEO
Well, there is -- every time a next-generation requirement comes up from an OEM, typically, there's some kind of process; right? There's a bid process. Sometimes it's formal in an RFP process. And whenever that happens with one of our competitors, competitors' customers, it's a competitive situation; right? So we have an opportunity to bid on that business. And if it's the right business for us to win from a profitability standpoint, to aggressively compete and hopefully win it.
So, yes, I think pretty much the way you should look at it ,is it's a design win business. You win a design for a certain generation or a certain platform. And then, when the customer goes onto the next new platform and the next new air link, it's a competitive situation and you have to re-win the customer.
Sera Kim - Analyst
Okay, great, and just last question. I know you haven't disclosed your part development plans beyond the Rev. A. I'm just wondering, can you talk about what percentage of your R&D spending is going towards the 3.6 and Rev. A versus newer network technologies, such as 7.2 and Rev. B, maybe?
Jason Cohenour - President, CEO
No, we can't provide that at this point in time, Sera, but I will say this. We have two R&D teams -- one in San Diego that is mainly CDMA oriented, and one here in Richmond, B.C. that's mainly GSM oriented. And they are roughly the same size.
Sera Kim - Analyst
