Welcome to Select Comfort's Q2 2016 earnings conference call. All lines have been placed in a listen-only mode until the question-and-answer session. Today's call is being recorded. (Operator Instructions). I would like to introduce Dave Schwantes, Vice President of Finance and Investor Relations. Thank you, you may begin.
Dave Schwantes - VP Finance & IR
Good afternoon and welcome to the Select Comfort Corporation second-quarter 2016 earnings conference call. Thank you for joining us. I am Dave Schwantes, Vice President of Finance and Investor Relations. With me today are Shelly Ibach, our President and CEO, and David Callen, our Senior Vice President and CFO.

The primary purpose of this call is to discuss the result of the fiscal period just ended. However, our commentary and responses to your questions may include certain forward-looking statements. These forward-looking statements are subject to a number of risks and uncertainties outlined in our earnings news release and discussed in some detail in our annual report on Form 10-K and other periodic filings with the SEC. The Company's actual future results may vary materially.
I will now turn the call over to Shelly for her comments.
Shelly Ibach - President, CEO
Good afternoon and thank you for joining our call. My average SleepIQ score this month is 81. Today I'll provide an update on our second-quarter results and highlight initiatives for the balance of 2016.
Our second-quarter results were in line with our expectations. Net sales were $277 million, up 1% from the prior year, and earnings per share were $0.03. These results reflect the recovery from our ERP implementation in our seasonally lowest sales quarter.
We are very pleased with the improvement of our customer metrics in the second quarter. We are now equal to or better than the prior year for our key metrics as we enter the third quarter. We also steadily improved operations and are on track to realize 50 basis points of gross margin improvement for the year.
Regarding the overall consumer landscape and retail environment, here's what we see and our response. Consumer behavior is sluggish and they need to be inspired to act. We are engaging customers with the benefits of our innovation. Economic growth will not come easily over the next few years and the consumer is in a constant state of change. These dynamics create opportunities for companies like us who are leading with digital assets, delivering benefit driven innovation and operating more efficiently.
From a mattress industry perspective, ISPA has lowered its 2016 outlook from 6.5% to 3.5% growth. We expect low teen sales growth for the year which is effectively mid-single-digit if you adjust for the ERP impact in 2015's fourth quarter.
There is a proliferation of new direct to consumer mattress brands that are focused on convenience. Direct to consumer is our core strength, and the new "it bed" will deliver both convenience and quality sleep at a compelling value.
The world is going through a digital transformation and many companies have yet to invest in a meaningful way. The investments we have made have transformed the Company, and digital is now at our core. We are delivering consumer wellness benefits with a relevant digital communication. We have invested more than $400 million into the Company through capital spending and acquisitions in the past five years, while returning nearly $300 million to shareholders through share repurchases. Our investments position the Company to achieve our vision of unparalleled sleep experiences and deliver superior shareholder return. This period of deep investment has strengthened our competitive differentiation, and we expect our strategy to deliver high single-digit growth and midteen ROIC long-term.
Here are additional highlights from the second quarter. Our focus was on regaining the trust of our customers, and improving online customer sentiment, which is now stronger than the prior year. We accomplished our goals in the second quarter through consistent and improving operating performance, a customer outreach program to those we disappointed during our ERP implementation, and activating loyal customers to repeat, refer and review.
The improvement in our traffic metrics followed our customer metrics, and strengthened throughout the quarter. Specifically, we had a 17 point trend improvement in online traffic in the last seven weeks of the quarter and exited on plan. New customer growth, sales and unit trends followed the same pattern with 15 to 16 point increases compared to the first half of the quarter.
Media delevered 140 basis points during the quarter. We increased media spending to support brand engagement as our customer sentiments improved. Sales conversion continues to be strong as our store teams become more proficient with their new CRM system. Year-over-year sales increases in FlexFit adjustable bases and SleepIQ is reflected in our ARU growth of 3% in the quarter, which was slightly higher than expected.
Improvements were mostly consistent with our expectations, yet overall traffic and sales were approximately 2 points lower than we anticipated. We have forecasted accordingly for the third quarter while also making adjustments to our advertising initiatives to create additional momentum. We continue to expect about 100 basis points of media leverage for 2016.
New store openings drove 6 points of growth in the second quarter and continued to perform at or above plan. We opened our 500th store in Eden Prairie, Minnesota and our first store in Alaska, our 49th state.
We also launched our 11th of 14 identified aggressive growth markets. This strategy remains a consistent, proven approach to develop large underpenetrated markets profitably within three years.
We are very pleased with our new capability of scheduling home deliveries in the stores at the time of purchase. We successfully implemented this experience in March for two-thirds of the country and have since extended to the remainder of our stores. We have seen immediate customer benefits, including faster delivery and improved customer satisfaction. This is one example of both a service and operating efficiency benefit enabled by the ERP system.
In the quarter, we also tested routing and scheduling variations to balance customer convenience with cost. While we are still learning, we do expect efficiency gains from this initiative by the fourth quarter.
We've also made progress in manufacturing productivity and we exited the quarter with rates stronger than the prior year. Fulfillment operations are improving, and we expect to be at prior-year levels by the fourth quarter. Our teams are streamlining operations and processes as they leverage our new system, and we expect significant operating margin expansion in the back half of the year.
Here are the highlights of the initiatives that we are advancing to drive demand in the back half and deliver low teens sales growth for 2016. Starting with traffic, our two most effective media types are national television and digital communication. Qualified unique visitors, defined as visitors to SleepNumber.com that take at least one action, is the traffic measurement that most closely correlates to our sales. Results are on pace with our expectations as we exited the second quarter.
We added two new TV commercials to our Know Better sleep campaign in the first half of the year with continued focus on consumer benefits, memorability and delivering brand interest.
We are also simplifying our online experience to increase consideration and generate additional store traffic. I highlighted in Q1 that we were building a digital marketing platform to optimize content and media for our target audience. This is now an internal capability and we are able to adjust digital media mix in real time and drive higher engagement from traffic. Other digital initiatives focus on referrals, retargeting prospective customers, and advancing SleepIQ technology.
Next week, we will take another big step forward in Connected Sleep. All SleepIQ customers will benefit from our new software release, which includes SleepIQ API. This new application program interface broadens the benefits of our technology. Customers will now be able to connect SleepIQ with other health and fitness apps and smart devices. New features will include notifications and sleep tips based on customers' individual data to drive an even better understanding of how to improve sleep and overall wellness. SleepIQ technology will now be a core feature on our m and i series beds and will continue to be an option with our c and p series beds.
Our organization is gearing up for the Labor Day event in Q3. We have refined our plans with learnings from the first half and are well-prepared for this important consumer sales period. We are rallying around eclipsing a significant Company milestone in September, 10 million lives improved.
Following the Labor Day event, we plan to launch the award-winning "it bed" by Sleep Number. We are targeting a new customer for our company with this brand, specifically a digitally savvy 25 to 34-year-old with a $50,000 income who is purchasing their first bed.
The "it bed" delivers a strong price to value equation, including both convenience and quality sleep. It ships fast, free and sets up in minutes. It adjusts, connects to customer's data driven life and provides insight through SleepIQ technology, all for $1,100 for a queen mattress. The It Bed brand launch will be digitally led and focused on online purchases. We will also test 50 store locations at launch.
New stores are an important source of our growth plans these next few years. We remain on plan with our market development strategy and ended the second quarter with 39 incremental stores over the prior year. We anticipate 5 to 6 points of growth from new stores in the back half of the year in addition to positive comp growth. We expect a record year of operating cash flows in 2016, and have generated $47 million for the first six months compared with $45 million for the same period last year.
Considering our expected strong cash generation, we have increased our share repurchase authorization to $300 million as of the beginning of the third quarter. We will continue to execute against our three cash priorities -- investing in our growth, financial flexibility, and share repurchases.
In summary, our transformation is complete and we are well-positioned to meet the expectations of a dynamic, demanding consumer, and accelerate shareholder returns. I appreciate our team's dedication and commitment to our customers' experience. We are excited about the opportunity in front of us, especially as we prepare to introduce significant product advancements next year to deliver what we believe will be the future of sleep.
Thank you. And now I would like to turn the call over to David.
David Callen - SVP, CFO
Thank you Shelly. We are pleased to continue to meet our operational and financial milestones as we recover from our ERP implementation completed last quarter. Our business performed relatively well considering the strong 17% sales growth we were up against from the prior-year quarter. Sales were slightly below expectations, which we offset by favorable operational improvement to deliver $0.03 of EPS. The residual carryover from the ERP implementation impacted Q2 sales by an estimated $5 million to $10 million with an associated $0.03 to $0.05 impact on EPS for the quarter, bringing the ERP impact isolated in the first half to an estimated $0.28 to $0.30 per share.
The second-quarter topline growth reflects a 6 percentage point step up in performance sequentially when you exclude the $21 million backlog benefit included in Q1 net sales. This is an important milestone as we return to high single-digit sales growth long-term.
Specific sales metrics for the quarter include a comp sales decline of 6% with a positive 7% two-year stacked comp. ARU of $4,206 was up 3% and units declined 3%. Our trailing 12-month average comp store sales of $2.3 million declined 6% versus the prior year largely due to ERP impacts in Q4 of 2015 and the first half this year.
Gross margin of 61.9% represented a 270 basis point sequential improvement over the first quarter of this year and was equal to the prior year. This marks another major milestone toward the accelerated profitability we expect beginning in Q4.
Improved customer experience, especially in delivery operations, drove lower returns and scrap charges in the quarter. As we learned to use our new tools effectively, these gains were partially offset by inefficiencies in routing density, third-party logistics, and order fulfillment. We expect actions already underway to drive improvements, especially in Q4.
Operating expenses of $169 million were up 10% versus the prior year and slightly favorable to our plans for the quarter. Sales and marketing costs, including depreciation on new stores, were up 6% for the quarter. This also includes 11% increase in media spending to support the brand. As expected, we incurred incremental depreciation of $3 million, primarily through the G&A expense line, and $4 million of incremental R&D costs for the SleepIQ LABS and advancement of our innovation pipeline in the quarter.
Our business model enabled us to generate $47 million in cash from operations year-to-date compared with $45 million the prior year-to-date. As planned, our lower capital spending meant our free cash flows in the first half were $23 million compared to $6 million the prior-year first half. We invested $24 million in capital projects year-to-date, primarily in new stores. We also repurchased $70 million of our common stock year-to-date, up 40% from the $50 million repurchased in the first half of the prior year.
As expected, during our seasonally low sales quarter, we ended the period with $16 million drawn against our $150 million revolving credit facility. As discussed previously, we expect to use the line for temporary support of seasonal operating needs.
Inventories were $74 million at the end of the quarter, as planned.
We are reiterating our 2016 guidance for full-year earnings per diluted share of $1.25 to $1.45. The guidance continues to assume low teens net sales growth for the year.
Specific to Q3, we expect mid-single-digit net sales growth largely from new stores. Please remember that, in the third quarter last year, we pulled forward approximately $10 million of sales ahead of our ERP launch in Q4. Also note that Q3 of 2015 included acquisition gains in G&A and income taxes that were offset by ERP launch costs.
Q3 this year will include approximately $0.08 of incremental R&D and ERP depreciation. Taken all together, we expect Q3 EPS in 2016 to be $0.05 or so lower than the prior year.
Here are a few other 2016 guidance callouts. We expect to deliver approximately 50 basis points of gross margin improvement in 2016. Targeted actions with our third-party logistics providers as well as using new ERP enabled home delivery capabilities and streamlined processes will drive results, especially in the fourth quarter and beyond. Sales and marketing costs are expected to be 44% to 45% of net sales for the full year. We continue to forecast approximately $60 million of depreciation and amortization in 2016. The bulk of the $12 million year-over-year increase is ERP depreciation flowing through our G&A expense line. We also expect approximately $12 million higher R&D costs for the year, largely SleepIQ LABS.
Our forecasted income tax rate is 34.5%. We continue to expect more than 100 basis points improvement in our EBITDA margin and to generate record cash from operations in 2016. We have lowered our capital spending forecast slightly to approximately $65 million while prioritizing our target of 535 retail stores by year-end and advancing the productivity of our website. We expect ROIC to exceed 13% for the year and expect share repurchases for the full year to somewhat exceed 2016 free cash flows.
And lastly, our outlook does not contemplate a worsening of consumer spending the balance of the year.
We are well-positioned to improve margins, leverage our business model, and deliver on our $2.75 EPS commitment for 2019. This will require high-teen EPS growth from the midpoint of our 2016 guidance adjusted for the estimated ERP impacts. This is in line with our expectations for accelerated profitability beginning in Q4 and a 17% EPS CAGR assumed with our long-range guidance.
I will close by adding my sincere gratitude to our highly dedicated and motivated Sleep Number teams.
With that, Sean, please open up the line for questions.

(Operator Instructions). Peter Keith, Piper Jaffray.
Jon Berg - Analyst
Thanks a lot. This is actually Jon Berg on for Peter tonight. Thanks for all the color on the call. First off, David, just circling back to your comments for Q3, I know, as you mentioned, I think you had a $10 million sales pull forward last year into the quarter as you prepared for that ERP launch which will now be a headwind. Do you think -- I guess under that scenario, do you think a positive comp is still possible for the third quarter?
David Callen - SVP, CFO
Thanks for the question. We are expecting most of the growth to come from the new stores, but do expect flat to positive comps in Q3.
Jon Berg - Analyst
Okay, great. And then I guess as you look at all the new store growth you've had here kind of over the last few years and where you're planning to go, what has kind of the cannibalization level been running and how do you expect that to play out as we go forward here? Do you think it's going to step up, or is there any way you could quantify that for us?
David Callen - SVP, CFO
Yes. We are seeing about the same cannibalization that we have seen historically, which is less than 20% from our new stores. We think that's directionally going to be the same going forward.
Jon Berg - Analyst
Okay. And then just one last quick one on the addition of SleepIQ I guess to the m and the i -- the i and the m series beds now. Will those beds then be increasing the base price, the $300 step up that is the option you've had thus far, or is there a bigger step up than that?
Shelly Ibach - President, CEO
No, that's the step up, the $299 or $300, yes.
Jon Berg - Analyst
Great. Thanks a lot everyone. Good luck for the rest of the year.
Operator
Budd Bugatch, Raymond James.
Bobby Griffin - Analyst
Good afternoon everybody. This is Bobby filling in for Budd. I appreciate you guys taking my questions. I just wanted to first touch on the gross margin guidance for the year. Is it now 50 basis points instead of the 50 to 100 basis points that we talked about last quarter? And if so, can you maybe give a little color on what changed within that guidance?
David Callen - SVP, CFO
Yes, glad to. Given where we are with our evolution and post recovery from the ERP implementation, we feel confident that our initiatives to improve our gross margin are really going to drive a benefit in the fourth quarter, and 50 basis points for the full year is the right target to have.
Bobby Griffin - Analyst
Okay. Is the 50 to 100 basis points cite for 2017 still something that you feel comfortable with?
David Callen - SVP, CFO
Absolutely. The margin improvements that we are delivering for this full-year -- and that's on a full-year basis, 50 basis points largely coming from benefits in Q4 and beyond, we still have line of sight for that 50 to 100 basis point improvement in 2017.
Bobby Griffin - Analyst
Okay, I appreciate that. And I also wanted to touch on units. Can you maybe give a little more color on what you're seeing from overall units? It looks like overall units were down 3% for the quarter while store count was up roughly 9%. Maybe what some of the initiatives are there through the back half to flip the unit cadence?
Shelly Ibach - President, CEO
Sure, Bobby. On units, we've stated before that, for the full year, we expect flattish ARU and the growth to come primarily from units. And of course, much of that will come in the fourth quarter when we are up against an easier compare.
However, I want to take you back to something I highlighted in the prepared remarks about the step up that we experienced between the first half of second quarter and the second half of second quarter. Along with the recovery of our customer metrics, we also experienced a similar recovery in step up in our online traffic, and then our sales in units followed that. So we are seeing the progression that we expected with units as we head into the back half. Again, units are primarily driven by bringing new customers to the brand, and that's where most of our initiatives are. Our focus this year is on bringing new customers into Sleep Number, either through referrals or reaching new customers with our other actions. (multiple speakers)
David Callen - SVP, CFO
I would add a little color on the quarter-to-quarter sequential improvement. Keep in mind that Q1 of this year benefited from the $21 million backlog carryover, and so the unit growth in Q1 was down probably on an adjusted basis around 6 percentage points. So that's marking a sequential improvement going from there to what we saw in Q2.
Bobby Griffin - Analyst
Okay, perfect. I appreciate that. And just a follow-up on Shelly's comments, two follow-ups for me and then I'll jump off is, one, Shelly, when you look at kind of the separation between the first half, as you detailed, and the second half, was that just the general consumer environment you're kind of pegging that as, or did you guys change your marketing message? Or how should we think about that? And then Dave, on the backlog, do you feel you've got the backlog down now to where it's kind of at more of a normalized level?
Shelly Ibach - President, CEO
Regarding the change that we experienced in the second quarter, let me start with the consumer environment has been very consistent for us since February, so we have experienced a more sluggish resistant consumer through that period.
Now, we've had our own internal challenges around the ERP implementation in Q1 followed by the recovery in Q2. And what we -- the pressure we had in Q2 in the first half of the quarter was related to where our online customer sentiment was, our referral metrics, all of the customer metrics based on the customers we impacted with ERP. So as we move those metrics and improve them to equal to or higher than prior year, that was midpoint in the quarter, and then that's when we saw our other metrics improve as well.
David Callen - SVP, CFO
Regarding the backlog, I just want to highlight that, yes, the backlog currently is normalized level, very similar to last year. But I just want to highlight again that we expect, over the next year, to cut our delivery times in half to seven days.
Bobby Griffin - Analyst
Okay, and then you will clear out some more of the backlog accordingly probably, right?
David Callen - SVP, CFO
Yes, exactly.
Bobby Griffin - Analyst
I appreciate the detail and you guys answering all my questions. Best of luck moving forward.
Operator
John Baugh, Stifel.
John Baugh - Analyst
Thank you and good evening. Just a couple of things, quick. One, Shelly, could you comment on how you're thinking about, I don't know, the second half as it relates to the election, your ad spend? Does it get crowded out? Do we see the election spend really cranking post-Labor Day so it won't impact Labor Day? Any color there?
Shelly Ibach - President, CEO
Yes. When we take a look at the back half, election year is always a bit dicey, as we all know. We are excited about the advancement in our digital communications, and that's a place -- I mentioned the digital media platform that we now have that we can react to real-time. And that's a capability we did not have four years ago or even a year ago, so when we are faced with changes like the election, and that will change from week to week through the back half, knowing that digital communications are second most effective media, and we are watching that real-time, and we can move it real-time each and every day to be able to respond to how customers are engaging. So, that's an agility point that we have now that we are excited about as we head into it.
John Baugh - Analyst
So you would expect you'll see some pressure on TV and you hope to be able to offset to some degree that impact with more digital? Would that be fair?
Shelly Ibach - President, CEO
Yes, digital initiatives -- and the second initiative that I would highlight is what we are doing with our loyal customer base and focus on referrals and using social to advance our referral behavior.
John Baugh - Analyst
Okay. And my second question was related to R&D BAM and the acquisition. You've referenced in the past how it should help with future product launches. I guess I don't expect you to tell us what those launches will be and when on this call, but I'm just curious whether there is any update. I know that the It Bed will drive some units post-Labor Day. Are there planned new beds as we move into 2017, or anything you can give us that you expect to see return on that investment as we move into 2017? Thank you.
Shelly Ibach - President, CEO
Great. I'll highlight three things around SleepIQ technology. First, I'll start with the advancement we have next week with SleepIQ API. John, what we've experienced on referrals is a higher referring rate from SleepIQ customers. So we know how important it is and continuing to advance our software in meaningful ways, reengages the customer and results in additional referrals.
Secondly, with the "it bed", we are very excited about this. It's to market within a year from the acquisition, and it is simple, convenient, and has strong value for the consumer on being able to adjust and have the benefits of SleepIQ technology. And then I mentioned at the end of my remarks about next year. Yes, we will have a very exciting product launch next year that will be a result of our advancement, and that includes the acquisition of SleepIQ.
John Baugh - Analyst
Great. Then just one final housekeeping. Your G&A came in certainly lower than where I pegged it. I can't remember, Dave, if you gave us some kind of dollar figure. You have certainly broken out the depreciation piece. But any sense of how to model that quarterly going forward? Thank you.
David Callen - SVP, CFO
Sure John. The run rate in the back half is going to be about $32 million a quarter.
John Baugh - Analyst
Great. Thank you.
Operator
Seth Basham, Wedbush.
Seth Basham - Analyst
Thanks a lot and good afternoon. The first question is just on repeat and referral mix. Could you give us a sense of where you are relative to historical trend and when you expect to return to that trend?
Shelly Ibach - President, CEO
Yes, we have returned to our historical trend. In fact, we exited slightly higher as we entered Q3.
Seth Basham - Analyst
That's great. And that's driven by some of your social initiatives and whatnot, so you'd expect that to improve from here to new highs?
Shelly Ibach - President, CEO
It is absolutely an initiative of ours. We are excited about what we are seeing with customers who own SleepIQ technology, and they are referring, as well as some of the social referral initiatives that we have initiated.
Seth Basham - Analyst
Got you. Okay. Considering that and the fact that your traffic really turned around nicely in the back half of the quarter, it points to some great momentum in the business in terms of interest in the brand. And I would think that should carry through to sales. Is there a conversion issue that you are seeing that's not leading to higher sales as a result of increased traffic and repeat and referral?
Shelly Ibach - President, CEO
Our conversion was strong, very strong, and as a matter of fact, we just had our national sales conference here last week and the energy -- it's great to hear the learnings from the stores on how they are using our new CRM capability. So no, conversion is where it needs to be as we look at the overall business, slightly higher as we went through the second quarter. And now we are well-positioned for the back-half goals that we've laid out.
Seth Basham - Analyst
Okay. Great. And then the last question for me for now is just on the It Bed. When you think about the contribution to your full-year outlook, is it material or are you just not building in much of any sales and profit from that into the full-year outlook?
David Callen - SVP, CFO
We are not building a significant amount of sales into our forecast for the It Bed at this point.
Seth Basham - Analyst
Very good. Thank you.
Operator
Brad Thomas, KeyBanc Capital Markets.
Brad Thomas - Analyst
Good afternoon everyone. Just to follow up on the last It Bed question, I think the 50-store initial rollout is a little smaller than what we tend to see. We tend to see new products in the entire chain, if I'm not mistaken. Maybe a little bit more color on the thought process of why you are testing it out and perhaps why the timing is post-Labor Day would be great to hear.
Shelly Ibach - President, CEO
Sure. A couple of things, Brad. First of all, from a timing perspective, we knew it would be late summer as we began to develop the bed with SleepIQ LABS at the time of acquisition last September. And we did have a small window before Labor Day but it was tight, and we are focused on flawless execution as we head into the Labor Day with our overall core business, and it's where we decided to keep our energy right now.
So post-Labor Day, we will launch -- we are primarily focused on online purchases. One of our key objectives with the It Bed is to learn. And we are learning from delivering a product that is very convenient and delivers on quality sleep. It ships in five days, it sets up in moments, and yet still has adjustability and SleepIQ technology. And we also have a simple online experience to complement the bed, and it's attracting a new customer to our overall brand. So we are staying focused there to be able to learn and make sure that we deliver a different brand experience than our overall master brand. At the same time, we want to benefit from having stores, and we want to understand selling this brand along with our full line, what that means and what it means from a cannibalization, or an additive customer. And we will learn that with 50 stores.
Brad Thomas - Analyst
Great. A housekeeping question on sales. You called out obviously in the press release the $5 million to $10 million residual effect from the ERP implementation. I think, last quarter, you had talked about a $4 million pull forward from 2Q sales into 1Q sales associated with being faster in deliveries than you initially expected. I guess can you just help us think about maybe what the $5 million to $10 million was and where there has been pull forward and where there hasn't been as we are all trying to reconcile all of these numbers? Thank you.
David Callen - SVP, CFO
We will try to keep you straight on all the moving parts. The estimated impact of the ERP residual impact on customers' experience, it was our estimate, we triangulated it based on the same measures that we used in the first quarter focused in on cancellation rates or returns that were above what we would normally see, and with those elements in mind, identified the range of $5 million to $10 million as the right range of impact for the residual ERP impacts. That's in line, generally, with what I had indicated last quarter, being about $10 million for the second quarter.
Brad Thomas - Analyst
Great. And then with respect to BAM Labs, 2017 is still a ways out here. But could you give us your latest thinking in terms of perhaps how accretive that business could end up being for you next year?
David Callen - SVP, CFO
Yes, we'll provide a lot more guidance at the end of 2016 with what we are thinking about for 2017. But at this point, we are committed to that that acquisition will be accretive in 2017, and it will be part of the driver for the 50 to 100 basis points improvement in margin that we are expecting as well as leading to product innovation sales and cost reductions in our products.
Brad Thomas - Analyst
Great. Thank you so much.
Operator
Jessica Mace, Nomura Securities.
Jessica Mace - Analyst
Good afternoon everyone. My first question is I was wondering if you could give a little more color on the increase in ARU. You said it was above your expectations, and mentioned some attach rates. I think the FlexFit was contributing to that. Were there any other trends in mix as far as premiumization or higher price points on like-for-like items?
Shelly Ibach - President, CEO
Yes. It was slightly ahead of expectations with the 3% growth, and we did see year-over-year increases with our partner snore feature and also SleepIQ technology. From a mix perspective, a little bit up and a little bit down, but, all in all, pretty balanced.
Jessica Mace - Analyst
All right, great. And then my second question, you mentioned to get to your target of $2.75 of EPS would require a 17% CAGR and earnings growth. Are there any buckets on expenses you can call out that would contribute to the margin expansion needed to reach that goal? Thanks very much.
David Callen - SVP, CFO
You know, just let me reiterate that it's based on our midpoint of our guidance adjusted for the ERP impacts. It's high teen growth rate. What I was referring to is when we initially provided our long-term guidance, it was 17% CAGR off of the 2014 earnings.
As far as bucketing the improvements, we expect, again, high single-digit topline growth. We expect to leverage the business model to deliver midteen operating profit drop-through rates over time, and we expect to repurchase shares that would be accretive to EPS over time. Those are the primary drivers of getting us from where we are to the $2.75.
Jessica Mace - Analyst
Great. Thanks very much.
Operator
Curtis Nagle, Bank of America.
Curtis Nagle - Analyst
Thanks very much. Just a quick question on store growth for second half of the year. So, it looks like a little bit of a pickup in terms of units. I guess how would that be spread between the two remaining quarters, and what are you expecting for store closures? And then just a follow-up, any commentary in terms of consumer credit trends you guys are seeing over the past couple of quarters?
David Callen - SVP, CFO
As we highlighted, I think the expectations for Q3 are for mid-single-digit sales growth, and that will largely come from new stores. We've said that we expect most of the growth to come from units and a little bit less from ARU in Q4. And you know, that's really true for the back half of the year.
As far as -- can you remind me of your other questions? I'm sorry.
Shelly Ibach - President, CEO
Store closures and --
Curtis Nagle - Analyst
Store closures, how many you have I guess remaining through the year, and then consumer credit trends.
David Callen - SVP, CFO
We expect to end the year with 535 stores in total. We don't generally break out total additions or closures. But in terms of our consumer spending trends, we are seeing the use of financing to be very similar to what we saw in the prior year.
Shelly Ibach - President, CEO
And you could weight the number of stores open similar to last year in the two quarters.
Curtis Nagle - Analyst
Okay. Thank you very much.

Just a couple of quick questions. Did the pricing on the "it bed" changed from your initial assumptions? I'm not sure if it was $1,000 before or approximately $1,000.
Shelly Ibach - President, CEO
Yes, we've always -- since our launch at CES, we've talked about around $1,000.
Mark Rupe - Analyst
Okay. And then I know there's a lot of details here on the call, so it probably speaks for itself. But at the beginning of the year, I think you kind of framed up the guidance for the first half of the year it would be 25% of the year and the back half 75%. And based on the first half, it's a little bit lower than maybe what the profile would assume. Is there anything else that's put in the back half a little bit stronger than maybe what you would've thought at the beginning of the year?
David Callen - SVP, CFO
Yes, as we called out on the last call, we said that we were spending on the ERP at the high end of the range, and that impacted us a bit heavier in the first half than what we had expected. But that's about the only thing, and that's a shift of a few cents.
Mark Rupe - Analyst
Okay. And then lastly, there's been a lot of commentary on the first half versus second half and the second quarter and thanks for that. Is it fair to assume, I think it's pretty clear that units then in the back half were positive.
David Callen - SVP, CFO
Yes, units --
Mark Rupe - Analyst
Perfect, thank you.
