Good morning. Welcome to the Analog Devices fourth quarter and fiscal year 2019 earnings conference call, which is being audio webcast via telephone and over the web. I'd now like to introduce your host for today's call, Mr. Michael Lucarelli, Director of Investor Relations. Sir, the floor is yours.
Thank you, Cheryl, good morning, everybody. Thanks for joining our fourth quarter and fiscal 2019 conference call. With me on the call today are ADI CEO, Vincent Roche, and ADI CFO, Prashanth Mahendra-Rajah. For anyone who missed the release, you can find it and relating financial schedules at investor.analog.com. Now on to the disclosures. The information we're about to discuss, including our objectives and outlook, includes forward-looking statements. Actual results may differ materially from these forward-looking statements as a result of various factors, including those discussed in our earnings release and our most recent 10-Q. These forward-looking statements reflect our opinion as of date of this call. We undertake no obligation to update these forward-looking statements in light of new information or future events. Our comments today about ADI's fourth quarter and fiscal 2019 financial results and short-term outlook will also include non-GAAP financial measures, which exclude special items.
When comparing our results to our historical performance, special items are also excluded from prior periods. Reconciliation of these non-GAAP measures to their most directly comparable GAAP measures and additional information about our non-GAAP measures are included in today's earnings release. As a reminder, 2018 was a 53-week year and thus included an extra week of operations. In today's remarks, we have normalized our fiscal 2018 results to a 52-week year so that our comments on annual growth rates make for more accurate compares. With that, I'll turn it over to ADI CEO, Vincent Roche. Vince?
Thanks, Mike, and good morning to you all. Well, we delivered solid fourth quarter and full-year results against what was a backdrop of challenging macroeconomic conditions and ongoing trade uncertainty. Importantly, we made progress positioning ADI for continued long-term success, which I will discuss in more detail shortly. In the fourth quarter, revenue was $1.44 billion, and adjusted earnings per share was $1.19. For the full year, revenue was approximately $6 billion, down slightly year-over-year, as double-digit growth in our communications market was offset by slower demand across other markets. Specifically, collective revenue from our B2B markets of industrial, communications, and automotive increased slightly compared to 2018, led by strong demand across the wireless communications sector. Given the current operating conditions, we continued to actively manage our business, reducing operating expenses. All told, full-year adjusted EPS was $5.15. We generated approximately $2 billion in free cash flow.
While this year's 33% free cash flow margin is below our long-term operating model, we continue to be in the top 10% of companies in the S&P 500. ADI is a diverse business across customers, products, and applications that positions us to succeed in any macro environment. In 2019, we added to our cutting-edge technology portfolio through strategic investments while partnering even closer with our customers. The resiliency of our business model in any economic environment is evidenced by our B2B revenue outperforming the industry in both fiscal 2018 and fiscal 2019. We're not standing still. To that end, let's turn to our priorities for 2020. Priority 1 is deepening customer centricity. We possess the broadest product portfolio, applications expertise, and manufacturing capabilities in high-performance signal processing. This enables us to solve our customers' toughest challenges at the intersection of the physical and digital worlds.
The factors driving customer demand are, first, our customers are facing a scarcity of available analog design engineering talent, and thus, they're increasingly turning to us for that expertise. Second, the challenges our customers face in the third wave of information and communications technology are becoming ever more complex. In this world, digital systems increasingly rely on real-world information to make mission-critical decisions, and the accuracy and the integrity of this information is becoming more important. As a result, our customers are partnering with us more deeply to get the full benefit of our technology capabilities and product inventions and innovations. We are uniquely positioned to provide the enabling solutions with our comprehensive portfolio of high-performance mixed signal, RF and microwave, and power management technologies. To that end, as we enter 2020, our opportunity pipeline value is at record levels and increased more than 15% year-over-year.
Priority two is the efficient use of capital. First, R&D is critical to our company's success, and in 2019, we invested $1.1 billion there. To continue this virtuous cycle of innovation-driven success, we choose our investments wisely, and when necessary, pivot quickly, targeting the most attractive opportunities, particularly across our B2B markets. This long-term approach to R&D allows us to continue to innovate and fortifies our position against any economic backdrop. Second, we're extracting value from our acquisitions to complement our R&D and drive long-term value creation. With the Hittite acquisition, we became the market leader in high-performance RF with a portfolio that spans DC to 100 GHz. Since the acquisition five years ago, we've more than doubled Hittite's revenue. In the last year, our RF franchise revenue increased over 30%, led by industrial and wireless communications growth.
The LTC acquisition added high-performance power management and precision signal processing to our portfolio, positioning us to provide more fully integrated solutions and capture additional value. Due to the combination with LTC, we're building our power pipeline, which is up nearly 40% over the past year, and beginning to deliver new revenue streams. For example, in power, we've won designs across 5G infrastructure, data center, and automotive that are moving to low volume production in 2020, ahead of a more meaningful ramp in 2021. This puts us on a path to double the LTC historical revenue growth rates in the years ahead. In addition, we're making steady progress on the next phase of our LTC cost synergies, which Prashanth will elaborate on in just a while. Third, we're committed to delivering strong shareholder returns.
Our target is to return 100% of our free cash flow after debt repayments to shareholders in the form of dividends and buybacks. In 2019, we returned more than 120% of our free cash flow to shareholders after debt repayments. Priority three is capitalizing on secular trends to expand our addressable markets and drive diversified growth. Some examples include, for example, in 5G wireless, we're pushing the innovation curve on our market-leading integrated transceiver by adding digital capabilities, algorithms, and optimized power solutions. This enables customers to scale channel count by eight times while managing size and thermals. 5G isn't just about wireless. It will also require a complete re-architecting of the core and wireline network to meet the 5G vision of gigabit speeds, low latency, and high reliability demanded by mission-critical applications.
This network expansion will require a significant upgrade of the backhaul system, opening a new revenue opportunity for ADI's optical and point-to-point microwave solutions. For electric vehicles, we have the highest performance BMS solution, providing customers with up to 20% more miles per charge than our competition. Next in our roadmap is revolutionizing how monitoring and controlling batteries will be solved, that is wirelessly. This creates a more accurate, reliable, and necessary approach to measurement for the entire battery life, from formation to implementation, to reuse. With the rise of Industry 4.0, factory floors are becoming more digital with greater sensing, measuring, and actuating activities. In turn, this creates additional demand for our precision signal chain franchise, as well as extensions to this franchise into new areas.
For example, our innovative software-configurable I/O solution enables greater flexibility across the factory floor. High-performance power is essential to managing heat dissipation as information density increases at the equipment level. However, it's not just about our core technologies. Digital factories are also creating new TAM for our suite of connectivity and sensor solutions. Last but not least, in healthcare, to build upon our strong growth trajectory, we're extending our high-end component franchise with integrated modules, increasing our BOM. We're also extending our signal processing hardware and algorithms into new areas such as glucose meters, surgical instruments, and digital health applications that predict and manage chronic disease. In closing, at the start of this year, I shared the adage with you that a rising tide lifts all boats, and that the true test of a company's strategy and business model is its performance during the low tide.
Despite the external turmoil, for the full year, we posted approximately 70% gross margins, best in class across the semiconductor industry, and almost 41% operating margins in line with our long-term operating model. As we look ahead, we're hopeful that market demand will improve as early as our second quarter. In an ever-changing world, we remain focused on being agile and responsive to market dynamics, demonstrating courage in creating and seizing opportunities, showing additional prudence in our investments while driving continuous improvement across every facet of our business. Longer term, the data era is creating an inflection across our industry. I believe that ADI's prospects are extremely compelling as our product portfolio is aligned with favorable secular trends that I believe will provide tailwinds for many years to come. With that, I'll turn over to Prashanth.
Thank you, Vince. Good morning, everyone. Let me add my welcome to our Q4 2019 earnings call. As usual, with the exception of revenue and non-OpEx, my comments on the P&L and our outlook will be on a non-GAAP or adjusted basis, which excludes special items outlined in today's press release. Let's start with fiscal 2019, which was a solid year for ADI. Revenue finished at $6 billion, down a modest 2%, while our B2B revenue was up slightly despite continued trade and macro uncertainty. As Vince shared, our margins continued to be strong. Gross margins were approximately 70% and operating margins were 40.6%. Adjusted EPS was $5.15. Free cash flow was approximately $2 billion. We repaid $850 million of debt, paid $780 million in dividends, and repurchased over $600 million of stock. All told, after debt payments, we returned 120% of free cash flow to our shareholders.
Now let's look at the fourth quarter. Revenue of $1.44 billion was down 6% year-over-year, as flat Industrial was offset by broad-based weakness across our other end markets. I'm going to go through some commentary on the individual markets. Industrial, which represented 52% of revenue in the fourth quarter, was flat year-over-year. Trends were similar to the previous quarter, where we saw strength in aerospace and defense, healthcare, and electronic test and measurement, offset by weakness across automation and memory test. These fourth quarter application trends were consistent throughout 2019, and for the full year, Industrial revenue decreased 2%. Our Industrial results highlight the benefits of having a diverse product portfolio and tens of thousands of customers across many applications. Communications, which represented 18% of revenue in the fourth quarter, was down 19% year-over-year, with both wireless and wired down double digits.
For the full year, comms revenue was up double digits, driven by a notable pickup in 5G-related revenue. As we have mentioned, the comms market is inherently lumpy. We believe this softness is largely timing based. We are at the early stages of the global 5G rollout. We remain confident in our expectation that our comms revenue will grow in 2020 and beyond, given our market leading position and higher content opportunity in 5G. Automotive, which represented 16% of revenue in the fourth quarter, was down 8%. While BMS continues to be a bright spot growing double digits, we did face SAAR headwinds, which impacted our other application areas. For the full year, auto revenue declined 6%, in line with the decline in vehicle sales. In total, fourth quarter revenue from our B2B markets decreased 6% year-over-year.
As Vince mentioned, full year B2B revenue increased slightly. Consumer, which represented 15% of revenue in the quarter, was down 7%, and our performance for the full year was down 16%, in line with our outlook. Moving on to the rest of the P&L for the fourth quarter. Gross margin was 68.4%, a decrease of 200 basis points sequentially. Approximately 140 basis points of this decline was related to a one-time inventory charge associated with a customer within our communications market. OpEx was $427 million, a decrease of more than 5% year-over-year. Sequentially, OpEx was down 2%, marking the fourth consecutive quarter of OpEx declines due to our discipline on discretionary spend and lower variable comp. Operating margins were approximately 39%. Excluding the one-time charge, operating margins were above 40%.
Interest and other expenses were down $6 million year-over-year, as we continue to focus on reducing debt. Our tax rate was 13%, which came in at the lower end of our guide. All told, adjusted EPS for the fourth quarter was $1.19, or $1.24, excluding the one-time inventory charge. Moving on to the balance sheet. Sequentially, inventory dollars decreased $28 million and days declined by 5 to 124. As a reminder, our target for inventory days is 115-125. As we have communicated in the past, ADI is currently in the process of closing 2 legacy LTC facilities. During this transition, we plan to carry an additional 5-10 days of bridge inventory to support our customers. Channel inventory ended the quarter at 8.5 weeks, above our 7-8-week range.
For the fourth quarter, our sell-in revenue was below sell-through. Fourth quarter CapEx was $51 million, and for the year was $275 million, or approximately 5% of revenue. Looking to 2020, we are forecasting CapEx to be slightly below 4%. Now on to the first quarter outlook for 2020. In our seasonally weaker first quarter, revenue is expected to be $1.3 billion ± $50 million. At the midpoint of guidance, we expect B2B revenue in the aggregate to decrease mid-teen year-over-year. There are a few items factored into this outlook. First, we are planning to meaningfully reduce channel inventory in the first quarter and return to our target range of seven to eight weeks by the end of the second quarter.
We expect 5G demand to remain modest through the end of this calendar year, with a positive inflection demand to occur in the fiscal second quarter as the global 5G rollout ramps. Lastly, in fiscal 2020, the Chinese New Year falls in the last week of our first quarter. During this time, there is minimal activity across our Chinese distributors. Turning to the rest of the P&L for the first quarter. Op margin is expected to be approximately 36.7% at the midpoint, mainly due to lower revenue and lower utilization. Our non-op expenses are expected to be approximately $49 million. For fiscal 2020, we are reducing the low end of our long-term tax rate and guiding 12%-15%. Based on these inputs, first quarter adjusted EPS is expected to be $1.00 ± $0.07.
As Vince stated, one of our priorities is the efficient use of capital. I want to highlight the actions we are taking related to this effort in the current environment. The first action is preserving working capital by managing inventory, both on our balance sheet and in the channel. In the fourth quarter, we reduced factory utilization and plan to do so again in the first quarter. To put this in context, our current factory utilization is at levels consistent with prior cycle troughs. The second action is restructuring, in line with our disciplined approach to managing cost and operational efficiency. In the fourth quarter, we executed a restructuring and realignment of our business. This restructuring, combined with the previously announced LTC facility closures, will result in $135 million of total cost savings over the next two years.
As we exit 2020, we expect to realize approximately $50 million of savings, with around 75% coming from OpEx and the balance from cost of goods sold. These cost reductions will begin in the first half. In 2021, after the facilities are closed, we expect to realize the remaining $85 million of savings in cost of goods sold. Together, these position us to drive operating margins towards the high end of our long-term operating model over time. The third action is continuing to return 100% of free cash flow to shareholders after debt payments. In 2020, we plan on paying down between $300 million-$500 million of debt. We expect to return all remaining free cash flow to shareholders through dividends and buybacks. In summary, the external environment will continue to present headwinds, at least in the near term.
As Vince noted, we are seeing early indications of improving conditions beginning in the second quarter. With that, let me turn it back over to Mike to lead our Q&A.
Thanks, Prashanth. Okay, let's get to our Q&A session. Please limit yourself to one question. After our initial response, we'll give you an opportunity for a follow-up. Operator, can we have our first question, please?
For those participating by telephone dial-in, if you have a question, please press star and 1 on your phone. If your question has been answered and you wish to remove yourself from the queue, please press the pound key. If you are listening on a speakerphone, please pick up the handset when asking your question. We'll pause for just a moment to compile the Q&A roster. Our first question comes from Vivek Arya from Bank of America. Your line is open.
Good morning, Vivek.
Hi. Yes, this is Jamie Zakalik on for Vivek.
Good morning, Jamie.
My first question is on gross margins. I know you mentioned that one-time inventory charge, but going forward, how should we think about the sensitivity of gross margins to sales and mix, and is there something else that could impact those things?
Great. Thank you for the question, Jamie. First, let me start by reiterating our model. 70% is our long-term model. As you saw in the good times, we were operating above that, closer to 72%+. In the last quarter and the current quarter, with some of the revenue compression, we're in the high 80s. Through a cycle, we're still going to see 70%. The way I'd kind of guide you to think about it is there are two factors, utilization and mix. Mix doesn't change, and given kind of where the outlook is, industrial is going to be above 50%. We have lower utilizations in the first quarter, and this is going to impact the first quarter margins and bring us down to that sub 70%. The first quarter does not have the reserve headwind, but it does have the lower utilization.
On a go-forward basis, what happens is really going to be macro dependent. As volume comes back, we will have pretty significant leverage from where we are. Then on top of that, I just mentioned the additional cost reduction actions that we're taking, $100 million in cost synergies exiting 2021, and roughly $15 million of that will come in by the end of this year. Do you have a follow-up question, Jamie?
Yeah. Great. Thank you. That was helpful. Just a quick follow-up on the 5G comms side of things. You guys gave some great color on timing, but I was just wondering if there was any specific geography or area that was weaker on the comms 5G side, or if it was more broad-based. Thank you.
Yeah, Jamie, the short-term downturn here in 5G was broad based. It was all regions and all customers.
Thank you.
Thank you. We'll go to our next call question.
Thank you. Our next question comes from Tore Svanberg from Stifel. Your line is open.
Yes. Thank you, and congratulations on managing through this environment. First question, if we look at revenues down 15% year-over-year for the January quarter, how would you qualify that between, A, seasonality, B, lowering channel inventory, and C, weaker end demand? Just trying to understand between those three, what's driving the down 15%.
Thanks for the question. First, the outlook is mid-teens in B2B. In that sense, on a year-over-year basis, I would say industrial does a bit better than mid-teens, maybe down about, say, 10% or so year-over-year. That implies, I would say, worse than seasonal sequential growth. Part of that is demand. Part of that is also reducing the channel. Automotive is right around that mid-teens % down year-over-year, and comms is down a bunch more than mid-teens, and down sequentially as well. On consumer, the math on that implies about 20% or so down year-over-year.
Tore, as a rough estimate, I'd say that if you took the combination of what we're doing in the channel plus the impact of Chinese New Year, roughly like a $50-ish million impact on a revenue impact to kind of how we're guiding the outlook.
Do you have a follow-up, Tore?
Yeah, thank you. That was really helpful. Follow-up for Vince. Vince, you talked about connectivity now for BMS, and including wireless. I assume that is based on your proprietary WirelessHART technology. If not, maybe you could elaborate a little bit on that, please.
Thanks for the question, Tore. We've got the highest precision battery management, the sensing and measurement portfolio. To that, we are beginning to sample this wireless technology. It's a proprietary, rugged, robust, self-healing radio technology. Yes, it is proprietary, based on proprietary ADI hardware as well as software stack.
Great. Thank you very much.
Thanks, Tore.
Thank you, Tore. We'll go to our next question.
Thank you. Our next question comes from Ambrish Srivastava from BMO Capital Markets. Your line is open.
Hi. Thank you very much. Good morning, guys. I had a question on distribution inventory, and I'm just confused in why the difference between the disti work down, the channel work down that your analog as well as broader diversified guys have seen, versus your channel inventory went up the last quarter. You're taking the action now, but just wanted to understand why the difference in timing, Vince.
Yeah. Ambrish, remember that we manage the business on a sell-through basis. We're reporting revenue on a sell-in basis, and over the course of 2019, our sell-in was roughly equivalent to sell-through. As we've seen revenue come down towards the later part of 2019, the levels in the channel have gotten outside of our preferred range of seven to eight. We're taking specific action. We began in Q4. We'll continue in Q1 with a goal that by the end of Q2, we will get channel inventory kind of back in that seven- to eight-week range. The result is that we're going to be putting less into the channel, and the channel is selling out.
The answer I gave Tore earlier is that roughly, if you include that plus the Chinese New Year impact, which is at the end of our fiscal first quarter, is at a rough estimate, kind of $50-ish million worth of revenue impact.
Yeah. Ambrish, I'll just add one thing with Vince and Prashanth said in their script. Our industrial business was only down about 2% last year, which I think versus the market performed very well. There's always timing with all the different things. On a performance basis, we outperformed in 2018 and again in 2019. Do you have a follow-up, Ambrish?
Yeah, I did. This was with respect to the write-down. Typically, in the analog world, inventory write-down usually results in a tailwind down the road. I was wondering, are we seeing something different here? I'm assuming, it could be a wrong assumption, that this is related to Huawei. Does that come back, and are you able to sell that inventory? Are we looking at, we always think of analog as companies with deep moats, which I'm sure you do, but are we seeing a change at Huawei that they're also developing analog parts that go into their infrastructure?
Yeah, let me take the first part of that, and I'm going to recap what I said in the prepared comments. We took a $20 million inventory reserve related to a one-time charge for a customer in the comms market. We were building to one forecast, and then the demand changed pretty rapidly after they were added to the BIS entity list restriction. It was our determination that it was the prudent thing to do, and absent another law change, we believe we have minimal to no more inventory exposure for this customer going forward. Is it possible to sell some of that inventory? It's possible, but obviously not probable given that we did take the reserve.
Yeah. I think the second part of your question there was regarding potential competition there in China. I think it's not a surprise that Chinese customers are going to look for security of supply. They're going to look for alternate sources. There's nothing to suggest that we're losing designs anywhere. As you said, the analog market naturally has deep and wide competitive moats given the complexity of the technology, the diversity that's required to be a stable long-term supplier into those markets. Of course, the life cycles as well are very long. I guess the way to look at it, the threat from local suppliers in China, well, it really isn't anything new. There's a lot of other facets that require just beyond the product. The quality levels we ship are in the parts per billion. The support required is very sophisticated, very complex.
I think the asymmetry between the skill sets and talents that we have as an analog supplier compared to anybody else, that asymmetry is pushing more and more towards ADI. The gap between the skills that we have and many others, that gap is growing. I think to just finish up my commentary here on China, it has been and will continue to be an important market, and we expect to be doing a thriving business there in the years ahead for many, many, many decades.
Thank you, Vince. Good luck, guys.
Thanks.
Thanks, Ambrish.
Thanks, Ambrish.
Our next question, please.
Our next question comes from Toshiya Hari from Goldman Sachs. Your line is open.
Hi, guys. Thanks for taking the question, and I apologize for any background noise. Vince and Prashanth, I think you both talked about a potential recovery in demand starting in the fiscal second quarter. Was that a comment specific to comms or was it more broad-based? I guess more importantly, what gives you the confidence to make those comments given the uncertainty both from a macro and trade standpoint? Thank you.
Okay. Why don't I start on that, Vince, and if there's anything you want to add.
Yeah.
There's some macro and some kind of specific to ADI. From a macro level, it's our take that we're kind of bouncing along the bottom. Certainly, there's ongoing uncertainty with the trade war that's impacting overall demand, and customers are putting a pause on CapEx spend. It is weaker than a year ago, but it seems to be stabilizing at this level. For comms and 5G, there is a lull between deployments. As I said in the prepared remarks, comms is inherently lumpy. It's very early days on the 5G. We're expecting demand to kind of stay soft through the end of this calendar year, but pick up nicely for 2020. As I mentioned in the remarks, we're expecting comms to grow year-over-year in 2020. Specific to ADI, we've got a couple things that are impacting our first quarter.
As I had mentioned, I think we've had a couple questions on this now. We are proactively reducing inventory in the channel. On top of that, the Chinese New Year, which is normally a non-event if it falls in the middle of a quarter, this time is falling at the end of our fiscal first quarter.
Yeah, I think the only other thing I'd add to what Prashanth has said is that, typically our first quarter is weaker than our second. There is a seasonality to that, particularly in the industrial and the automotive businesses. That's how we see things shaping up at this point in time. As Prashanth has said, we're confident that 5G demand is really poised to ramp at the beginning of our second quarter. I think that's the summary of demand here for you.
Thanks, Toshi. Do you have follow-up?
I do. Thank you. Then Prashanth, you talked about $135 million in cost reductions over the next, I suppose two years. How should we think about that number kind of sticking to the P&L? In other words, should we expect a pretty high percentage drop through to margins, or should we expect you guys to reinvest some of those savings in your high priority areas? Thank you.
Thanks, Toshi. Let me break that down again. We had talked about $100 million of cost savings when we closed down the two facilities. In addition to that, we took some actions in the fourth quarter to generate an additional $35 million. Those actions are in process. In 2020, we would expect to exit the year with about $50 million of those savings in the run rate. That will be split between OpEx and cost of goods sold. We'll have those savings sort of feather in over the course of the year. That is, at this point, kind of roughly a net number. That is the expectation that we're going to be able to drive most of that down through the P&L and into the EPS number. Thanks, Toshi.
Thanks so much.
Let's go to our next question.
Thank you. Our next question comes from William Stein from SunTrust. Your line is open.
Great. Thanks for taking my question. I want to address the optimistic April commentary. By my math, I think normal seasonality in April is about up three, and it sounds like the real recovering end market is comms infrastructure related to 5G. I'm wondering if there's any insight into other end markets, and if normal seasonality is up three, do you think we wind up posting meaningfully better than that? It would seem an outside possibility that we could be up year-over-year in that quarter, but any comments would be helpful. Thank you.
Thanks, Will. I was going to give you some basis of seasonality. We don't guide outside of a quarter, I would say, but to give you some context around comms being a growth market for us in 2020, despite the slow start. Seasonally speaking, industrial and 2Q is up, call it 5%-10% sequentially. Automotive's up also probably, call it 5%-10% maybe sequentially. Both those seasonally are up. We don't have visibility into those orders today, but from a seasonally standpoint, there is some tailwinds to those businesses. Communications, we're talking about a pretty big uptick in 2Q, which helps drive that business to grow for 2020. Do you have a follow-up?
Sure. Any comment as to where we are in the comms and-- pardon me, the consumer end market? We know there was this Force Touch design win that's been sort of fading from the model you declined this year. Maybe an outlook as to the coming year in that end market would be helpful, both in that sort of one charismatic design win and then maybe the core business. Thank you.
Yeah. My sense during 2020 is that we will have a continuing headwind. It's lasting a little bit longer than we initially thought. I think 2020, we expect it to be down in the range of 10%-15%, and it relates really to the ongoing mix issue in our portable business. What I'd like to report to you is that I believe overall that 2020 will mark the bottom for this business. The diversity of our products across products, across customers and applications is stronger than we've seen actually for several years. Based on that diversity, the strength of our pipeline and the diversity of our pipeline, that gives me the optimism that we're going to get back into a pretty solid growth trajectory, I think, in the 2021 and beyond period.
Thanks, Will.
Thank you so much.
We'll go to our next question, please.
Our next question comes from Chris Caso from Raymond James. Your line is open.
Yes. Thank you. Good morning. My question's on the automotive market. I think your comments were that it's looking down 6% year-on-year this year in line with industry units. I presume you're still gaining some content there. Is the difference there inventory that's come down? Perhaps you could, if that's the case, what's the setup as we go into 2020 as perhaps some of that inventory normalizes?
Yeah. Thanks for the question, Chris. Let's do this in two parts. I'll kind of lay out how we're thinking about our auto performance in 2019, and then let Vince talk about a bit more on the growth drivers. As a recap, our fourth quarter was down 8%, the full year was down 6% year-over-year, in line with SAAR. We saw that across all applications on the year-over-year decline, except for BMS, which continues to show very strong double-digit growth. As we look to 2020, I'll let Vince kind of talk about the outlook for auto 2020 and beyond.
Yeah. During the past year, we've grown our pipeline of designs across the globe with all the key automotive customers. I think one of the areas that I'm most pleased about is in our power portfolio, which cuts across all the various sub-application areas in automotive. I'll give you a couple of examples. We've won an integrated power management solution for a market-leading tier 1 radar platform. We're the key reference design at a market-leading vision camera supplier. Given the strength of our infotainment business as well in DSP and audio signal processing solutions, we've been able to bring more power management from the LTC portfolio into that particular suite of applications as well. We've talked before about our A2B solutions. Today, that only represents kind of very low single digits of our auto portfolio. The design pipeline is gaining robustness.
At this point in time, we've got design wins at around 14 OEMs, half of them are currently in production. My sense is that over the next three years, we can double the size of our A2B business. Also, the other facet of A2B is that the TAM for it is expanding into being able to participate in active noise cancellation and power delivery. Prashanth has touched on the BMS side of things. That will continue to be, we believe, a strong growth driver for the company, probably up again double digits in 2020. On the autonomous vehicle side of things, we're sampling a CMOS-based radar solution that doubles the dynamic range against anything else that's out there from our competitors.
I think we've some very good innovation drivers in the business, as well as the fact that we are bringing the LTC portfolio into many new accounts in new geographies. Hopefully that gives you a sense for what's going on in the auto sector.
Thanks, Chris. Do you have follow-up?
I do. Thank you. The follow-up question will be on production. You talked about being at cycle trough utilization rates. What would be the plan going forward if you did see some of these indications of improvements going the second quarter? Would the plan be to start increasing production at that point? Generally, how are you looking to manage inventory as you go through next year with the understanding that you're going to be keeping some of that bridge inventory for the fab closures?
Great. Yeah. Thanks, Chris. I guess the way to think about it is we're comfortable utilizations are at trough levels, and you can see the impact of that on our gross margins. As the demand comes back and revenue improves, then we'll have great leverage from an internal manufacturing on being able to capture that demand with new manufacturing. In addition to that, we mentioned we're taking the channel down, so there will also be likely some opportunity to provide product into the channel to meet that growth. We're setting ourselves up for what we believe is a good trough in Q1, and then we'll grow from here.
Great. Thank you.
Thanks, Chris. Cheryl, we'll move to our last question, please.
Thank you. Our last question comes from Harsh Kumar from Piper Jaffray. Your line is open.
Yeah. Hey, guys. Thanks for squeezing me in. Thanks for managing the business extremely well and actually taking actions to get better profitability. Head one on gross margins. All things put together based on what you've said, we should think about gross margins for the January quarter, take the 140 basis points charge that you had. Prashanth, is that a good way to think about it and down maybe 50, 60 basis points?
I think maybe you're saying the same thing, Harsh, we're essentially going to swap the inventory charge with the underutilization. That's probably how you should think about gross margin for the first quarter, is we don't have the recurring inventory charge, we do have the headwind from kind of trough factory utilization levels as we kind of bottom out in the first quarter. Do you have a follow-up, Harsh?
Got it. Thank you. Yes, please. Just real quickly, in the auto business next year, do you think with all that's happened this year with the flushing of production and SAAR being down mid to high, sort of 6%-7%, do you think we're at a point where we can basically say that automotive for ADI will grow next year on a year-over-year basis?
It's very hard in what has been a very uncertain environment in automotive over the last several quarters. Very hard to call. I think if SAAR stabilizes, my sense is that we'll have a normal year. For the last five years, we've been outgrowing SAAR. My expectation is that if SAAR stabilizes, given the length of the product life cycles of our legacy business as well as the new designs we have, that the business should behave normally, and we should outgrow SAAR. One of the things as well that we've got, I think we've mentioned in the prepared remarks as well, is that our power business is poised given the design wins that we've got across infotainment and safety systems in particular. We expect that during the course of the year here to gain momentum and start to show meaningful revenue in the 2021 period.
Okay.
Thanks, guys.
Thank you, Harsh.
Thank you.
Thank you, everyone, for joining us this morning. Copy of the transcript will be available on our website. All available reconciliations and information can also be found there. Have a happy Thanksgiving. Thank you again.
