More information about other risks that may impact the company's business are set forth in the risk factor section of the company's prospectus and reports on filed with the SEC. Also with the exception of revenue, all financial numbers discussed today are on a non-GAAP basis, unless specifically noted otherwise.

Non-GAAP financial measures are not intended to be considered in isolation or as a substitute for results prepared in accordance with GAAP. A reconciliation between our GAAP and our non-GAAP measures as well as a discussion of why we present non-GAAP financial measures are included in our earnings press release that is available on our website.

Before moving on to the financial results, I'd like to announce that AOI management will present at three investor conferences in March, including the Raymond James' Institutional Investors Conference in Orlando on March 3, the ROTH Conference in Laguna Niguel on March 9, and Piper Jaffray's Telecom, Media and Technology Conference in New York on March 11.

We hope to have the opportunity to see many of you there. Now, I'd like to turn the call over to Dr. Thompson Lin, Applied Optoelectronics' President, Founder and CEO..

Thank you, Maria. Thank you for joining us today. For 2014, AOI achieved revenue of $130.4 million, representing growth of 66%, which outpace the competition. I am proud to say that we delivered this growth profitably, reporting a non-GAAP net income of $10.4 million or $0.68 per diluted share for the full year.

While the growth is impressive, the end of the year [ph] had changed. Fourth quarter revenue came in at $36.4 million, while up 53% year-over-year, it was below our initial guidance of $39.5 million to $41.5 million.

As we previously reported, our fourth quarter results was impacted by a supply issue with an externally sourced optical subassembly, therefore we are unable to ramp production levels for our new 40 G data center transceiver as planned.

Demand for our data center product remained very strong, and out of this supply issues, sales of our data center product were within our expectations. We had reported data center revenue of $14.9 million, up 153% year-over-year. Our cable TV revenue was up 21% sequentially and in line with Q4 of last year.

Our sequential growth in cable TV was mostly driven by continued shipment of recent design wins. Revenue for our fiber-to-the-home product was above our expectations and came in at $5.7 million, as our foundational WDM-PON customers took final deliveries under the contractual obligation.

Overall, in 2014 AOI made significant headway and we would like to thank our employees for their dedication and hard work. In 2014, AOI shipped over 1.9 million lasers compared with only 0.7 million in 2013.

Our data center business experienced phenomenal growth with annual revenue reach $64.5 million, 232% increase over the $19.4 million reported in 2013. Revenue from cable TV product totaled $47.4 million in 2014, in line with prior year.

As cable broadband providers prepare to upgrade their network with DOCSIS 3.1 technology, and walk through major consolidation activities. Last September we introduced a family of transmitter and receiver products that are fully compliant with the new DOCSIS 3.1 standard.

As the largest cable TV OTN equipment supplier, we believe we are well-positioned to benefit from this expected rollout. AAOI achieved a record 34.6% gross margin in 2014 compared to the 29.4% gross margin we delivered in 2013.

The significant 516 basis points increase in the margin is primarily attributable through an increase in mix of higher margin product, driven by the sales of our data center transceivers and new design wins in cable along with increased production volume.

On the operation side, we moved to a larger factory in Taiwan, with nearly three times the production floor space of our previous facility. And they also prepared to break around on our new facility in Sugar Land to expand our R&D and laser manufacturing capabilities.

We remain confident in all outlook for strong growth in our data center and cable TV business in this year. Our [ph] product line is very strong and we are excited by all prospective and overall revenue opportunity.

We will also continue to focus on pursuing new opportunities with customer across all of our markets by making timely investments in capacity and R&D to further solidify our position as the leading supplier of advanced optical products. With that, I will turn the call over the Stefan to present the detail of our Q4 performance and outlook for Q1.

Stefan?.

Thank you, Thompson. Total fourth quarter revenue was $36.4 million, up 53% year-over-year and in line with third quarter revenue of $36.5 million. Our data center revenue in the fourth quarter totaled $14.9 million, representing a 26% decrease from Q3.

39% of our data center revenue was derived from our 40-gigabit per second data center product, below our estimate of over 50%. As Thompson mentioned, 40-gigabit per second data center shipments were delayed due to a supply and quality issue with certain optical subassembly components sourced from an external supplier.

This issue was isolated to one product, a new 40-gigabit per second data center transceiver design win that we expected to ship in the fourth quarter. As a result of the supplier issue, we were not able to ship the quantities of this product we had expected.

We have been working very closely with our supplier to resolve this matter, so that we can increase shipments of this product to our customer. On the positive side, the transition from 10-gigabits per second to 40-gigabits per second in the data center is rapidly accelerating. And to our knowledge, the demand is outpacing capacity worldwide.

Given our vertical integration and manufacturing capabilities, we are working to ramp development of key 40-gigabit per second components to help alleviate shortage.

Additionally, as you may recall, the advanced light engines used for these products to combine the outputs of multiple laser transmitters is based upon technology we internally developed for our WDM-PON OLT transceivers.

Given the use of the advance light engines and our vertical integration model, we believe that AOI has a very strong competitive position to continue its above market growth, as the transition to 40-gigabits per second and ultimately the transition to 100-gigabits per second progresses.

Looking into 2015, we have already built our first 100 gigabit per second qualification unit, and these are under testing now. We expect to deliver them to customers soon. While these initial units are only several of the types that will ultimately be needed by our customers, the testing of these first units is a significant milestone.

Based upon the strong 40-gigabits per second demand, an initial experience with our 100-gigabit per second product, we maintain our expectation that data center revenue will grow by more than 45% over our 2014 level. Turning to our cable TV market.

Revenue from cable TV products in the fourth quarter was $14.7 million, up 20% from Q3 and in line with the $14.0 million that we reported in Q4 of last year. The sequential increase in CATV revenue was driven by continued shipments of recent design wins.

We continued to make progress on our DOCSIS 3.1 development efforts, and have already shipped customer samples of several DOCSIS 3.1 products. We are beginning to see initial orders for these products in the first quarter, as we expected.

Demand for DOCSIS 3.1 products should ramp modestly in the first half of the year, which is ahead of MSO's announced deployment schedule. Sales are expected to increase in the second half as all of our required DOCSIS 3.1 products become available. In total, we continue to expect our CATV revenue to grow more than 20% in 2015 compared with 2014.

In the fourth quarter, we had three customers that contributed more than 10% to our total revenue; a data center customer at 36%; a CATV customer at 11%; and an FTTH customer at 11%. For the full 2014 year, one data center customer contributed 46% to our total revenue, and this was our only greater than 10% customer for the year.

As we mentioned to you last quarter, while AOI will continue to focus on a small group of very large customer, diversifying our customer base, especially within the data center market is a key objective for the company.

We are pleased to announce that in Q4 we completed the qualification process and achieved two new design wins with a large new data center OEM customer. We have already begun initial shipments to this customer and expect them to ramp throughout the year.

However, at a relatively conservative ramp rate, as we work to prove ourselves to them, and we become more closely integrated into their supply chain. Moving down the income statement. Q4 total gross margin was a record 36.0%, an increase of 270 basis points from Q3, primarily due to CATV product mix and a higher percentage of FTTH revenue.

Turning now to operating expenses, which totaled $9.5 million compared with $8.9 million in Q3. In Q4, OpEx as a percent of revenue was 26.2% compared with 24.4% in the prior quarter. On an annual basis operating expense were 27% of revenue, slight improvement from last year's 28%.

R&D expense was $4.2 million or 12% of revenue, relatively flat on a dollar basis compared with Q3. Consistent with our plan, we continued our investments in 100-gigabit per second data center products and DOCSIS 3.1 technology. For the full year, R&D expense was $15.9 million or 12% of revenue compared with 11% in 2013.

We will continue to balance R&D investment appropriately in order to capture market share and promote growth at both the top and bottomlines. Sales and marketing expense was $1.6 million or 4% of revenue, in line with the previous quarter. For the full year, sales and marketing expense totaled $5.9 million or 5% of revenue compared with 5% in 2013.

G&A expense was $3.8 million or 10% of total revenue, up $0.6 million when compared to the previous quarter. For the full year, G&A expense was $13.4 million or 10% of total revenue compared with 12% in 2013.

Non-GAAP operating income in Q4 was $3.6 million or an operating margin was 9.8%, an improvement of 97 basis points when compared with the prior quarter operating margin of 8.8%. And in Q4, we achieved adjusted EBITDA of $5.7 million or 15.8% of revenue, up from 13.0% in Q3. For the full year 2014, we generated adjusted EBITDA of $16.3 million.

Non-GAAP net income after-tax for the fourth quarter was $4.0 million or 11.1% of revenue compared with $3.1 million or 8.6% of revenue in the previous quarter and $0.3 million in Q4 of last year. We generated non-GAAP net income of $0.27 per share, up from $0.20 last quarter.

GAAP net income for Q4 was $0.7 million or $0.05 per share compared with $0.10 in the prior quarter. The Q4 weighted average fully diluted share count was approximately 15.2 million shares. Turning now to the balance sheet.

We ended Q4 with $40.9 million in total cash, cash equivalents and short-term investments compared with $45.8 million at the end of the previous quarter. Cash flow provided by operations was $6.1 million.

We made a total of $16.4 million in capital investments in the quarter, bringing our full year CapEx to $41.1 million, above our previously announced outlook of approximately $35 million.

The spending, that was in excess of our plan, was mainly directed at additional production equipment needed in Taiwan for production of our 40-gigabit per second data center product. As we noted, the strong book-to-bill ratio in the fourth quarter and the supply constraint globally, both support this investment.

Also most of the equipment purchased can be repurposed to 100-gigabit per second production, when this technology begins production later this year. As of December 31, we had $33.8 million in inventory, an increase of $0.7 million from Q3. Accounts receivable increased to $31.6 million compared with $24.2 million last quarter.

This increase is mainly due to the timing of order shipped within the quarter, along with the payment terms of customers involved. Moving to our outlook. For Q1 of 2015, we are entering the quarter with very strong bookings and forecast the demand and a book-to-bill of 1.7.

However, we are moderating our expectations to reflect supply constraints for 40-gigabit per second data center component. We expect Q1 revenue to be between $35.0 million to $36.5 million, representing 41% to 47% year-over-year growth. We expect Q1 non-GAAP gross margin to be in the range of 34.0% to 35.0%.

Non-GAAP net income is expected to be in the range of $2.0 million to $3.2 million. And non-GAAP earnings per share between $0.13 per share and $0.21 per share, using a weighted average fully diluted share count of approximately 15.3 million shares. With that, I will turn it back over to the operator for the Q&A session..

[Operator Instructions] We'll first go to Troy Jensen from Piper Jaffray..

Can you guys give us a more detail on, well, a couple of things on the 40 G stuff? What was the revenue shortfall in the fourth quarter? And if you can give us any color on what does the Q1 guidance imply for 40 G contribution?.

So as we noted, the 40 G contribution was about 39% of our overall data center revenue. Whereas we had earlier said we thought it could be 50%. And the shortfall was due to this supplier quality issue that we disclosed..

So Stefan on the supplier issue, is it a volume problem from the supplier or is it quality problem with the parts you're receiving?.

That's a great question Troy. We'll try to message that correctly. In the fourth quarter, we identified a quality issue with parts that we were receiving from a particular supplier. I want to emphasize, we identified that problem internally, and we stopped any shipments prior to those going out to the customer.

So we don't believe there is any customer affecting impact or potential of products that got out to the customer with any defect in them. So it took us some time, as you can imagine, to understand the nature of the problem, work with our supplier to identify the root cause of that problem, put in place a fix and verify that that fix was effective.

During that time production had stopped, because we didn't want to be producing any more products that could potentially have a defect. So once we've identified that problem and instituted the fix, production has restarted and we're ramping production very quickly. We're in daily contact with the supplier and production is ramping up quickly.

But because of the delay there, I mean we're not yet meeting the production goals that we had set out at this point..

So there was no change in the supplier, just to be able to work to the problems, so there is no recertification or qualification that's needed.

Correct?.

That's correct..

And then as far as with DOCSIS 3.1 stuff, do you feel like that is ramping through expectation?.

Yes, DOCSIS 3.1 is basically on our expectations. As we noted, we've started shipping samples of couple of products there. We have a number of additional products in the queue. We do expect to start shipping, I would say, initial volumes of products very soon, which is ahead of the MSO's deployment schedule.

And we've talked about this a little bit in the past. But basically the DOCSIS 3.1 products are backwards compatible with DOCSIS 3.0. So in a lot of cases, we expect to see DOCSIS 3.1 revenue coming before the MSO's announced schedules for DOCSIS 3.1 field trials and things like that.

Just because it's backwards compatible and they might as well go ahead and order the 3.1 compatible products rather than the older 3.0 stuff, if they can..

Can you tell us what does the Q1 guidance imply for a tax rate? And when do you expect to be a full tax paying corporation?.

The tax rate in Q1 is very low, just the 2% tax rate, basically. And we haven't given any forward guidance to say, when we expect specifically to be full tax paying, because all of our income is not in the U.S. We have some overseas, in particular in Taiwan, which has a lower 17% tax rate. We don't expect our blended tax rate to be the full U.S.

tax rate of 35%. It will be somewhat less than that, but we're not there yet..

And we'll now move to Simon Leopold form Raymond James..

Just a couple of things I wanted to follow-up on. One is, in terms of how you're thinking about the mix for this March quarter. I presume the fiber-to-the-home business is going to head to a level of maybe $1 million to $2 million a quarter. I think that's what you had talked about previously.

I just want to check where do we see that settling? And then grounding out the mix discussion, I'm a little bit confused, because I would normally expect the cable business to be seasonally down sequentially in March, but you're talking about some issues hampering the data center.

So can you help us understand how to think about the segment contributions in March?.

I think directionally on the fiber-to-the-home, I think you're thinking is correct. Certainly, we were winding down the last contractual obligations with our foundational WDN-PON customer in Q4. So that resulted in the outsize contribution, I think that we saw in Q4. I would now expect that to recur in Q1.

So directionally, I think on the FTTH revenue, you're in the ballpark there. With respect to the other segment, as we noted, we have extremely strong demand. I mean it's worth emphasizing that demand has continued beyond just the orders that we saw in Q4. The bookings even in Q1 remain very, very strong.

So the issues that we have are really related to the supply constraint, not any lack of demand. We have very good demand and very sustained demand. So really what we expect to see is the FTTH, correction, the data center revenue will certainly come back above what it was in Q4, because we want to be able to deliver more in Q1 than we could in Q4.

The problems that we encountered in Q4, as I said, are basically resolved and now we're just ramping the production. And so it's a matter of how much can we delivering in Q1. On the cable TV side of things, as you know Q1 revenue in cable TV in particular is seasonally down, correct about that.

I think again directionally in terms of where cable TV is that's what I would expect to see..

And then in terms of looking out longer-term for the year, I certainly appreciate you've given us full year guidance on cable TV. I wonder if you could give us some thoughts about the consolidation or pending consolidation among the large U.S.

operators, how and if that can effect to your business in terms of the timing of sales?.

That's a good question, Simon. I mean we've talked about that a little bit in the past. I've gotten that question a lot.

I think really the first order, I don't want to say it doesn't have any effect, but both Time Warner and Comcast has individually said on numerous occasions that they do need to spend more money in the future to upgrade their network.

The business that we're getting in DOCSIS 3.1 in particular, initially at least is going to be for field trials and things like that, that are virtually certain to go ahead regardless of any merger or lack thereof. So I guess the short answer to the question is, in this year, I don't really see a big impact one way or the other.

Longer term than that I guess there could be some impacts, depending on how the merger shakes out, whether it's one company or two going forward, but I don't expect it to be a big impact in 2015. And to the extent that we have any visibility into that I mean we've already baked that into our expectations for the year..

And just one last one for me. In the past you've talked about securing data center wins in China, obviously they didn't break into the 10% customer ranks yet.

Can we get an update of how those particular customer projects are evolving?.

Sure, Simon, yes. We talked about that a little bit in the call that we did secure two design wins for this customer. And we do expect revenue for them to ramp throughout the year. But we did also cautioned in the call that we expect that ramp to be somewhat muted.

It's a new customer relationship, and as with any new customer relationship it takes time for them to get to know us better, for us to sort of improve that that we're capable of meeting their expectations, and for us to get better integrated into their supply chain. So things are going well. We're on pace, on schedule.

Orders will be ramping up throughout the year, but I wouldn't go too crazy on that in the short-term, as we're kind of getting integrated with them more fully..

We'll now go to Paul Silverstein from Cowen and Company..

I'm just curious to Simon's question, which I believe was specifically about Huawei.

I thought you all had previously identified Huawei a year or two ago, and so is the customer in question, the OEM in questions, is that Huawei or are we talking about a different OEM? And secondly, and probably, just going back I think with Troy's question on the 40-gig impact.

Is the message that you take 50% of thereabout, subtract 39%, that's the dollars that we're foregone by virtue of the supply problem? And the related question would be, it sounds like you don't believe, you're not concerned that that business has gone away from you that the customer in question is waiting for your ability to shift as opposed to having reallocated the order to somebody else who could ship, because they didn't have supply a supply constraint?.

So on the question about the OEM that we're talking about. We haven't disclosed the name of that. As you can imagine, we have pretty strict non-disclosure arrangements with the customer. So we can't really disclose who that name is.

We did talk about the fact that we have achieved these two design wins and that we expect to revenue to ramp up throughout the year. If and when that become a 10% customer, obviously, then we'll have to disclose them and that will be okay. But at this time, I can't comment on the name of the customer involved.

Your second question I think was about the magnitude of the supply problem in Q4. So it was in the vicinity of a $5 million shortfall that we encountered in Q4 due to this issue. So that helps factoring on the magnitude of it for you. And then your third question, I'm sorry, I forgot what it was.

Paul, could you repeat the third question?.

Stefan, I recognized there's not a lengthy period of time, but the customer question, assume AWS, they are waiting for you to ship as opposed to having reallocate that order to another vendor who could ship --.

That's right. Yes, thanks. No, we don't see any indication that they've reallocated this order. In fact, I mean we've continued to see new orders flowing in from them. So I don't think there is any problem there. I believe, as we mentioned in the call, that there is a lack of supply globally for this type of product.

And so from that standpoint, I think, while the customer clearly would love to have had more delivery than they've got, I think we're still well-positioned to be the first supplier basically. In other words, we're supplying more than I believe anybody else is, even with our relatively limited supply capability in the fourth quarter..

And going back to the OEM, the two design wins, you did make clear, this is within OEM, I assume that means a switch equipment suppliers as opposed to an end-customer like in AWS, and Microsoft and Alibaba, is that correct?.

That's correct..

And just to be clear, if I may, am I mistaken that once upon a time sometime in the past that you all had referenced Huawei or maybe I'm confusing you with someone else..

To be honest, Paul, I don't know what we said about Huawei. We have had discussions with Huawei in the past. I don't know specifically. I'd have to research what we may or may not have said about in the past..

The only point where I'm going with this Stefan is just, if you have referenced Huawei in the past and you're now talking about a new OEM, it won't be Huawei, it'd be somebody else, as opposed to. I recognize you can't tell us you have to [technical difficulty]. So it's possible it could be Huawei or may not be Huawei..

Look I'll put it this way, we may have talked at some point about potential Huawei business, but we have not counted them as a customer in that sense at this point..

So the risks of being [ph] dense. Again, I understand you have do --.

[technical difficulty] new customer in fourth quarter, we would characterize them as a new customer in the fourth quarter..

We'll now go to Krishna Shankar from ROTH Capital..

So can we assume that you will catch up with some of the constraints on 40-gig optical transceivers in the second quarter? Do you feel comfortable with the supplier ramping up production of the corrected parts and meet demand some time in Q2?.

So that's a good question. I want to try to characterize this correctly. We definitely are going to shift more of that product in the fourth quarter, correction, in the first quarter than we did in the fourth quarter. So from that standpoint, we're going to be ramping up.

We have a very, very strong backlog of orders for that product and others, as I mentioned. So the limitation to our guidance really is about our ability to secure enough supply of raw materials and to be able to turn that raw material supply into finished goods and ship it during this quarter.

So I think, look to our guidance, the upsides of our guidance is we get more components, more raw materials earlier, and can actually ship more. And of course, the flipside to that is the risk to the guidance is, we get less raw materials than we think we are going to at this point, and that would result in shortfall.

But it's purely based on our ability to secure the raw materials and to produce those products from that raw material..

So at the same time, we are ramping up our internal capacity too. So we can make sure we have the resource to increase all of our capacity and minimize the risk for the futures upright..

And then in terms of gross margins, very good progress in Q4.

Can you talk about the trajectory of gross margins for the year, given the growth metrics you've laid out for the data center and the cable business?.

So we had obviously very strong gross margins in the fourth quarter. There were a couple of things, unique things that happened in the fourth quarter, some of them related to the FTTH revenue, the influx of FTTH revenue and other things. So we're not going to give specific guidance exactly on the gross margin for the rest of the year.

But I think the guidance that we gave in the first quarter is what we should look at. And most likely, it's going to be in that kind of realm.

But what is going to be at play in the first quarter, is really some increase in cost related to pushing the production of these data center products and counterbalancing that of course with cable TV increase or relatively higher level of cable TV revenue, relative to what we got in the first quarter of last year.

And more of that's being in higher-end sort of DOCSIS 3.1 or new design win type products. So those are going to be the two balancing factors for the gross margin..

And then my final question, any updates on other customers for your FTTH products that you can talk about?.

That's a good question. We have had some ongoing discussions with different customers. I think those discussions continue along. We don't have anything that I would consider to be substance enough to report at this point.

But things continue to move forward with a couple of different customers and we remain optimistic about that technology in the future..

We'll now go to Richard Shannon from Craig-Hallum..

I have a few follow-up here. I guess maybe first on the data center.

Stefan, I didn't catch your comments, maybe to scratch your line here, but did you mention the two design wins with this customer here and whether they were 10-gig or 40-gig?.

We did not. No, we haven't given indication on that..

Obviously, it's good to get another customer lined up here, and I don't want to celebrate that, but how about visibility into gaining some other customers and qualifications that look like they may finish in the foreseeable future.

How should we think about that?.

We continue to have good discussions and good progress on sales with a lot of different customers. I don't want to comment on anything, like we did with this fifth customer. I don't want to comment on anything prematurely, so we haven't given any kind of indications about other new customers.

But as those opportunities start to jell more and start to become sort of more realistic, we'll certainly keep everybody apprised to that..

Talking about the component issue that effected your fourth quarter, is that something that will also potentially be something that would impact you as you get into 100-gig as well or is that a generally different product design?.

No, it's a different product design. The issue that we had I don't really think was specifically a 40-gig problem in the sense that it couldn't have happened at some other data rate, but it was just one of those things that happened sometimes with relatively new products.

We did shift some of those products in Q3 and into Q4, so it wasn't like it was our very first shipment, but it was very early in the products lifecycle. We were pushing to ramp up quickly. And it's just one of those things, sometimes when you push a little to hard on the supply chain, we don't always get the results that we expected.

So I think there is a lesson to be learnt here is that, we probably need to be cognizant about pushing our supply chain harder than we perhaps are to, but I don't see that. Certainly, in this particular problem, I don't see any chance of it repeating in 100-gig..

Couple of more questions for me.

I guess, again on 100 gig, I just want to clarify that you're not including 100-gig in your data center revenue growth and perhaps you said 45% this year, is that correct?.

That's correct..

Actually two more questions for me.

Any thoughts on how we can think about CapEx spending for this year?.

We haven't given any guidance on CapEx for the year. We did obviously spend a little more than we expected on CapEx, especially in the fourth quarter. And I think that as Thompson mentioned, you know, we are working very hard to ramp up our internal production capacity to be a viable second source for some of these components.

And I think that represents a lot of the spending that we did in the fourth quarter. We will continue to invest in R&D, in particular, in production equipment, as the orders come in. I mean as we see visibility into those. So I would expect that we're going to continue to spend there.

I would also remind you that we are in the new building here, so it's going to be a CapEx intensive year. But I wouldn't expect to take out the building expenses and other things that is going to be vast and more expensive in terms of equipment and machinery than it was last year..

Just last quick question again on data center.

Obviously, you're going to have or expect to have a good year in 40-gig, but how about 10-gig this year? Is that something that's going to be the growth driver for you or how should we thinking about that?.

Well, I wouldn't say it's going to be a growth driver. It's also not going to fall off a cliff either. I think there is a lot of demand for the 10-gig..

Stefan can I rephrase [multiple speakers].

Do you expect 10-gig will grow this year?.

Overall, in the data center, I would say, no. We do have some other applications for 10-gig that perhaps could offset that. But to be honest I'd have to go back and add this two together to see if it's representing an overall growth or not..

And that is all the time we have for questions today. I'll turn the conference over to Thompson Lin for any additional or closing remarks. End of Q&A.
