Before we get started, I'd like to remind you that this morning's presentation contains forward-looking statements. Statements other than historical facts made during this call may constitute forward-looking statements and are not guarantees of future performance or results, and involve a number of risks and uncertainties. Actual results may differ materially from those in the forward-looking statements as a result of a number of factors, including those described from time to time in Resideo's filings with the Securities and Exchange Commission. The company assumes no obligation to update any such forward-looking statements. Additionally, during our call today, we refer to certain non-GAAP financial information. A reconciliation of our GAAP to non-GAAP results is included in the company's earnings press release and accompanying presentation, both of which can be found on the investor relations section of our website.
We identify the principal risks and uncertainties that affect our performance in our annual report on Form 10-K and other SEC filings. With that, I'd like to turn it over to our President and CEO, Mike Nefkens.
Thanks, Michael, good morning, everyone, and thank you for joining us on today's call. Resideo is now three quarters post the Honeywell spin, and I am happy to report that we had another solid quarter. We are finally starting to see some normalcy after all the spin work, and we are pleased with the progress against our strategic initiatives. We have settled into our new HQ in Austin, Texas, which enables us to have the leadership team in one location. Also, spin-related distractions are minimizing, and the field teams have been able to go deep with our pro customers. We have also been able to spend time with many new investors. Most important, our Q2 was strong, keeping us on track to hit our previously provided guidance for 2019. Let's get right into it.
First, we'll update you on our overall results for the quarter, then we'll discuss the results for each of our business segments. Third, I'll walk you through our progress in the market and some of the exciting acquisitions we've made to position us for growth acceleration. Last, we'll end with our financials and second half outlook. Turning to slide three, for the second quarter, revenue came in at $1.242 billion, up year-over-year 4% on a GAAP basis and 6% on a non-GAAP constant currency basis. From a top-line perspective, we're pleased that growth is spread evenly across our two segments. Adjusted EBITDA after the Honeywell reimbursement payment came in at $81 million and $116 million excluding the reimbursement payment, a solid performance driven by a combination of top-line growth and continued cost management.
Product mix headwinds around our new product launches continued but were partially offset via cost containment. Adjusted EPS was $0.19 per share, and GAAP EPS was a loss of $0.09 per share due to tax effects related to the Honeywell reimbursement agreement. All in all, a solid quarter on both revenue and EBITDA. Turning to slide four and our segment performance. Revenue growth was spread evenly across our two segments. For our ADI Global Distribution business, we continue to see solid organic growth in the Americas and EMEA, driven by security and life safety, as well as expansion of the professional AV growth initiative. We added to our ADI product offering, announcing a distribution agreement with Samsung Pro, we continue to win high-value new business throughout North America.
We're also pleased to report that ADI was recently highlighted in Security Systems News, in addition to being recognized as the top distributor used by SDM Magazine's SDM 100. Turning to our Products & Solutions business. P&S reported mid-single-digit growth. Security had another solid growth quarter as we continue to take share resulting from the launch of our new ProSeries platform. In comfort, we saw strong volumes in the new T9 and T10 pro-connected thermostats. In our RTS business, we launched a next-generation universal defrost control for heat pumps. We did see an in-quarter slowdown in the RTS OEM channel, in particular with our hot water heater OEM customers.
Now driving harder on the organic side, we boosted our R&D spend as part of our previously announced strategic initiatives. We expect to announce new product launches in water, comfort, air, and security in the second half of the year. On the inorganic front, we completed two acquisitions in the quarter, which I'll talk more about shortly. Looking at P&S segment adjusted EBITDA, both comfort and security are seeing margin pressures due to product mix headwinds, specifically the ramp-up of our new security platform and lower margins on connected thermostats. We are working to offset these with cost containment and supply chain and sourcing process improvements. I also want to call out the incredible strides we've made on improving our supply chain. As you may know, we had some supply chain headwinds pre and post-spin.
Due to new supply chain leadership and process changes, we're delivering more on time than ever before, and our delivery metrics are the best they've been in five years. This improvement will allow us to be more aggressive on the growth side. Moving to slide five. Some of you may remember from last quarter, I walked through our markets in detail. On the chart, we have our two businesses, ADI Global Distribution and Products & Solutions. In P&S, we have broken out our business by product area and their associated addressable market and estimated market growth rates. We provide some select competitors in our growth versus market on a 12-month rolling basis. The investors I met with in Q2 really liked this chart and asked for updates when there are changes. Today, I want to highlight some new developments since the last quarter, and there are two.
First, in the previous quarter's chart, we noted our security business is growing at market on a 12-month rolling basis. With two solid growth quarters behind us, we are now moving that box to green as we are growing above market and taking share. Second, for our Residential Thermal Solutions business, as previously noted, we've seen a slowdown in the OEM segment, primarily water heaters. As a result, we are adjusting the market growth of the RTS segment down to reflect changes in the market. Even though that market has slowed, we continue to win in that segment. Closing out on the chart, outside of security DIY, where we really don't play, we have a solid market position in all the segments we play in, and our objective is to further accelerate our growth in these segments.
Turning to slide six, we are seeing solid progress in our long-term growth strategies. A critical part of our strategic initiatives to bolster growth is small tuck-in M&A to strengthen our position in the key home categories of air, water, energy, meaning gas and electric, and security. During the quarter, we acquired technology from Whisker Labs, complementing our connected thermostats offering with industry-leading energy management solutions. We also acquired LifeWhere, which uses machine learning and analytics to predict potential failure on critical home appliances. Both of these acquisitions, along with the Q1 Buoy acquisition in the water area, strengthen our position in being able to offer whole home solutions. Our plans are to launch in Q4 with the Pro channel, a new set of offerings combining our core business with these new acquisitions to offer true next generation whole home solutions.
This launch will bring to market new products and services resulting from our 2019 investments. Thank you. I'd like to turn it over to Joe to provide financial details on the quarter.
Thanks, Mike. Last quarter I highlighted some of the volatility in our GAAP results due to the impact of the Honeywell reimbursement agreement. This quarter, there was little variance in the GAAP and adjusted reimbursement expense. There was a large adjusted tax expense impact that brought down adjusted EPS for the quarter. This will normalize for the balance of the year. Our EBITDA outlook for the year remains the same, and we'll touch on guidance in a few minutes. We expect revenue seasonality in the third quarter as we transition between the cooling and heating seasons, reflecting the typical seasonality of the business. We are more than confident we will mitigate any weakness with cost reductions. We expect margin pressure to continue, we have performed well year to date from a revenue perspective, allowing us to maintain our EBITDA outlook.
Our cost reduction programs remain on track, and we expect to realize $10 million in savings from them this year. You'll notice in our disclosures that we're reporting one-time repositioning costs related to our $50 million cost reduction program of $25 million, illustrating that the cost takeouts are well underway. Moving to slide eight. Our financial position remains solid and continues to position us to focus on growth. As I've mentioned in previous calls, the early part of the year is when we typically use cash, so you can expect to see our balance sheet reflect this. Cash usage was driven by a buildup of inventory and payments related to the Honeywell reimbursement agreement. We expect to release the majority of the increase in the next 12 months. Total debt decreased as we amortized a small part of our facility.
With $350 million undrawn and available on our revolver, we are confident that our financial position is strong and continues to support our strategic initiatives and growth plans. Slide nine presents our complete full year guidance. We are reiterating our full year guidance from a revenue and EBITDA perspective, with revenue growth of 2%-5% and the upper end of the adjusted EBITDA range of $410 million-$430 million. As I mentioned, we do expect modest revenue growth in the third quarter in line with our typical seasonality, but that will be offset by cost efforts to maintain our EBITDA target, and we expect to maintain our revenue target range as well. We also confirm our cash taxes to be paid for the year at approximately $75 million. Our priorities continue to be growth and deleveraging, and we expect that to remain unchanged in the near term.
We are confident in our balance sheet, and we are making steady progress towards deleveraging with our long-term leverage target at two times. Now I would like to turn the call back over to Mike.
Thanks, Joe. Thanks to everyone who joined us for today's call. We maintained our momentum in the second quarter, delivering strong financial results in both revenue and EBITDA, putting us on track to hit our previously provided guidance for the year. Our financial position remains strong and right where we need it to be at this point in our journey. Our strategic initiatives are firmly on track with exciting product launches planned for the second half of the year and in 2020. With this momentum, we are moving into a position where we can truly put the pro at the center of the home to provide industry-leading whole home products and services. Thank you. I'll now turn it over to Michael to open up Q&A.
Okay. Our first question is from Ian Zaffino from Oppenheimer.
You called 80. Okay. Thank you very much.
Great.
Can you guys just walk through the cadence of the margin improvement in the back half of the year. You call that ADT. What's the actual margin dilution that's causing? What can you ultimately mitigate that to? Also, as your product mix changes away from ADT to some more third parties, what's the impact on margins there? Thanks.
Hey, Ian, this is Mike, and I'll start and then probably hand it off to Joe here. If you take a look at the second half of the year, the big step up is going to be on growth. We'll be doing about $100 million more in Q4 than we did in Q1. That is very typical for us. It's what we did last year, and it's what we did the year before as well. That's step one, and we're confident. As we move from the cooling season to the heating season, that is a typical seasonality that we see in this business. Our reasoning for it is there's higher trade sales versus OEM sales. The trade sales are higher margin sales than the OEM contracted numbers, so that always helps us.
The other is, if you take a look at our security business, and our security business this year, and we've been pretty clear about this, with the launch of the new platform, as we started, it's down about eight points of margin from where the last platform was at the end of its cycle, which is pretty typical. We will, as volumes ramp up, we'll be getting a couple points back there towards the end of the year as well. The real margin improvement is going to be higher trade sales in the second quarter versus OEM sales, which have higher margins. Higher heating. Our heating products typically have higher margins as well, as we're selling more gas valves and other type products. Then the third is going to be some improvement that we're going to see on the security margins from where they currently are.
Ian, this is Joe, and in addition to that, you'll remember that we have called out $10 million of SG&A savings that we're going to have. That'll primarily be in Q4. The other thing, you ask an important question on the cadence. If you recall, in Q2 and Q3, those were our primary quarters for investment in our new products that we're bringing out. I don't know if you remember that, but if you look at the margin profile, Q1, 2, 3 to 4, those investments actually are being made in 2 and 3 and have the biggest impact. You'll see an increase in gross margin and even a margin in Q4 based on the business items that Mike brought up and the cost items that'll be lower in Q4.
Okay, thanks. Just touching on the segment and market overview slide. You have pro security growing 2%-4% and then DIY growing 10%+. What are your customers telling you about what the professional install market is doing and how it's really faring against maybe some of the new entrants on the DIY side? Is it a real competitive threat? Or is pro security going to be able to continue to grow like this? Thanks.
As I said in my prepared remarks, we really don't play in the DIY sector. We've got a couple entry level products that are typically kind of hook products to get people to move into the pro side. Our focus is on the pro security piece. We believe what we're doing from a market perspective and the new products that we're launching are going to be true market making products and going to be much simpler for the end user to use. We're hoping and we're seeing business models changing now from long-term commitments, contract commitments for pro security to shorter, which we think is going to really prop up the pro market. Our view on that is we want to push that pro security market.
We're growing faster than market now, and our job is to make sure that with the dealers and the other partners that we have, that we're providing them world-class products so that they can compete and truly show a higher value in the pro product versus the DIY product. As you know, Ian, I call the DIY product awareness products. Those products are more for if you want to see your dog running around the home, you want to know if someone's at the door, those kind of things. The pro products are true monitoring in the home, professional monitoring. Two very different things for me.
Okay, great. Thank you very much for the color.
Thanks, Ian.

Okay, Ragan, we'll take the next question.
Hi, this is Jeff Kessler at Imperial Capital. With regard to non-ADT business in the pro market, what are the medium and some of the smaller, but maybe let's shift it to the medium regional companies asking for, as you begin to change your product line and advance it in the fourth quarter, what are they asking for that is different or additive to what they have now to keep their value proposition up and higher than, if you want to call it the new competition?
Hey, thanks, Jeff. This is Mike here, I'll answer that. Looking at security, we will be rolling out our new ProSeries platform to the general market in Q4. That in 2020, we'll be rolling it out in Europe. We have launched it with our largest customer, and we will be rolling it out to general market in Q4 and then into Europe next year. The differences on what this product does versus the previous generations of product, it is a fully modular product, meaning that it will eliminate the number of truck rolls that our dealers need to make as technology changes. The best example of that is, as cellular technology changes, as it goes from 4G to 5G, they won't have to roll a truck anymore.
They'll be able to send a card straight to the consumer, and the consumer can just plug it right into the panel. Versus in the past, they'd actually have to go and replace the panel. The overall cost of the product is much cheaper, and it is going to give our dealers a competitive advantage versus some of the older technologies out there. It simplifies installation, it's easier for training the installers and much more interactive, a much better web interface and phone interface and it's really future-proofing a lot of the radio sunsets that we've seen out there in the past. That's the big difference, and that's why the largest dealer in the U.S. has gone 100% with us and our largest customer as well is really betting on our product as it's going to really change the profile of their business.
A follow-up question on ADI. They have really only one competitor of size in the security side. I'm wondering if your plans for ADI also include any level of comfort given that I know that there are different channels that comfort both heating and air conditioning are sold into. Is there a possibility for ADI to begin to get into that business as well?
Yeah. Looking at our ADI business. Right now, our ADI business focuses, as you said, on low voltage security. Their biggest growth area outside of that is AV right now, so professional AV. That's an area we're pushing really hard in. Also, the third item is enterprise connectivity. If you take a look at the connected home and the smart home, what we're really about is making the smart home simple. Where our ADI team, if they're able to sell a connected thermostat, any of the other connected products, they will do that. Our plan, Jeff, is that they will be selling connected products in the areas of air, water, security, and the behind the wall stuff that we call energy. I wouldn't see them selling a lot of non-connected products in the comfort space.
That's the way we're pushing that team, and we're seeing a pretty good uptake there already.
Does the margin mix change at all?
You know what? As you know, it's very product centric. It depends on the actual product itself. There is some opportunity there. I have tasked that team with finding 200 basis points of margin improvement over the next two years. Rob and team are all over that. Part of that will be exactly what you said through expanding deeper into connected products.
Great. Thank you very much. I appreciate it.
Yeah. Thanks, Jeff.
John Lovallo from Bank of America Merrill Lynch.
Hey, guys. Thank you for taking my questions. I'm just trying to get a better handle here on some of the numbers. Maybe we can start with just the commentary around cost control. If I look at 2Q adjusted operating profit, it was below our model. It seems like it may have been below your initial thoughts for last quarter. Appears to be some volume, some mix, and some investment spending. Gross profit, it was about $20 million lower than we had expected. It seems like EBITDA in the quarter was supported by $22 million or so of lower legal claims and spin-off costs. I guess the question is twofold. One, do you anticipate the benefit from these legal and spin-off costs continuing? Two, outside of that, where are the cost saves opportunities that you guys think will manifest in the back half here?
John, how are you doing? This is Joe. We would expect that we have continued savings on the SG&A side. We have several programs underway to drive the $10 million attainment this year and the $50 million run rate improvement for 2020. We are driving across the costs in the company overhead, as well as looking at gross margin improvements as well in supply chain. There are multiple opportunities that we're working currently. I would expect continued SG&A improvement as we take costs out of that structure, and you should see some improvement on the gross margin line as well.
Okay. Maybe just going to slide seven on the EBITDA walk and looking at the market moderation bucket. There appears to have been a little bit of cushion in there, perhaps. If we look, we're bullish on the new construction cycle and repair and remodel as well. I'm just curious what happened in the quarter that allowed you to become $10 million more positive on that bucket, because if you look at housing starts, they weren't particularly strong.
They didn't really move from our original number of 1.2 million housing starts. As we look at that, it hasn't moved very much, and we brought some conservatism into the bridge there, just because we didn't have good visibility. As you know, 100,000 decline in housing starts equals $7 million of EBITDA. That hasn't happened yet. There's been no change. We thought it made sense to actually just cut that in half.
Yeah. John, this is Mike here. My view on that was, we got through half the year. The way we had the market moderation really modeled is we really felt $10 million in the first half and $10 in the second. Getting through half the year, we felt pretty good about that and really didn't see any moderation headwinds. We've kept the additional $10 into the second half.
Got it. Thanks, guys.
Thank you.
Okay. With that, I'll hand it back over to President and CEO, Mike Nefkens, for closing.
Great, guys. Listen, thank you for joining the call. I really appreciate it. A lot of great questions as always. As I said in my prepared remarks, we had a solid Q2. There truly is momentum building right now. The investment programs that we've driven this year, we accelerated a lot of investment from 2020 into the year so that we could launch some of these new products I'd refer to at the end of the year. That's all moving in the right direction. I'm really excited to get those out to market. We really feel there's some true market makers in there in all areas of our business. It's all about execution. We've shown in Q1 and Q2 that we can execute. Our commitment is to continue that trend going forward.
We look forward to, I know I'm meeting many of you here over the next two days. Thank you for that. Also a quick call-out. We are at the NYSE today. We've been asked to actually open the market today, so we'll be up on the stand ringing the bell, and hopefully we can get great momentum here into the second half of the year. Thank you for attending the call, and look forward to talking to you next time.
Thank you. Ladies and gentlemen, that will conclude today's conference call. Thank you for your participation. You may now disconnect.
