Greetings, and welcome to the CSW Industrials, Inc. Fiscal 2027 First Quarter Earnings Call. (Operator Instructions) Please note that this conference is being recorded.
I will now turn the conference over to Alexa Huerta.
Alexa Huerta - Investor Relations
Thank you, Julian. Good morning, everyone, and thank you for joining CSW Industrials' Fiscal 2027 First Quarter Earnings Call. Joining me today on the call is Joseph Armes, our Chairman, Chief Executive Officer, and President of CSW Industrials and James Perry, our Executive Vice President and Chief Financial Officer.
Earlier today, we issued our earnings release, updated investor relations presentation, and quarterly report on Form 10-Q, each of which is available on the Investor section of our website at www.ir.csw.com. Today's call is also being webcast, and replay information is included in the earnings release.
Before we begin, I would like to remind everyone that today's discussion will include forward-looking statements. These statements reflect our current expectations and assumptions and are subject to various risks and uncertainties that could cause actual results to differ materially. Additional information regarding these risks is included in our earnings release, our comments on today's call, our annual report on Form 10-K, and our other filings with the SEC. We do not undertake any obligation to update any forward-looking statements except as required by law.
With that, I will now turn the call over to Joe.
Joseph Armes - Chairman of the Board, President, Chief Executive Officer
Thank you, Alexa, and good morning, everyone. The exceptional fiscal first quarter results we reported today demonstrate the power of a disciplined capital allocation strategy laser-focused on growing shareholder value through market cycles. We are reporting all-time record revenue, adjusted EBITDA, adjusted earnings per diluted share, and operating cash flows due to the resilience of our businesses, the efficiency of our operations, and the successful integration of our recently completed acquisitions.
Guided by our enduring capital allocation strategy, since May 1 of 2025, we have invested approximately $1 billion to consummate 5 highly accretive and synergistic acquisitions, including the transformative additions of MARS Parts and Aspen Manufacturing, plus 3 smaller but still immediately accretive acquisitions across our Contractor Solutions and our Specialized Reliability Solutions segments. As I mentioned earlier, the integration of each of these businesses has gone very well.
Simultaneously, we have continued to return meaningful capital to shareholders. During the quarter, CSW returned a total of $28.4 million in cash to shareholders through $23.5 million of open market share repurchases and $4.9 million in dividends. Our continued investment in our own shares demonstrates our strong belief that our equity has been undervalued relative to our growth and profitability, and cash flows, thus representing a compelling investment opportunity.
Concurrently with our share repurchases, we also delevered during the quarter, reducing our net debt-to-EBITDA ratio from 2.55x at fiscal 2026 year-end to 2.37x at the end of the fiscal first quarter through the reduction of net debt plus growth in our EBITDA. Our balance sheet strength gives us the flexibility to exploit all capital allocation alternatives open to us. End market momentum remained constructive despite the various dynamics in the macroeconomic environment during the quarter.
All 3 of our business segments generated strong top line results accompanied by margin expansion. Our Contractor Solutions segment is growing and expanding margins. Benefiting greatly from the comprehensive product offering created by the addition of MARS and Aspen, we are positioned to serve our customers well as we move through peak cooling season. We continue to expect this segment to outgrow the end markets served, which would result in mid- to high-single-digit organic growth through the cycle.
Our Specialized Reliability Solutions segment delivered robust, organic revenue growth with an EBITDA margin in excess of the 20% target that we have for this segment. The integration of the 2 recent acquisitions continues to provide accretion, and we expect to show continued margin strength for the full fiscal year. We continue to work toward the exit of the Greco business in our Engineered Building Solutions segment. Excluding the Greco business, the segment generated organic revenue growth, a strong EBITDA margin, and we exited the quarter with record order backlog, reinforcing our confidence in the segment's outlook and margin trajectory.
At this time, I will turn the call over to James for a detailed review of our financial performance, and then I will return afterward with a few closing comments.
James Perry - Chief Financial Officer, Executive Vice President
Thank you, Joe, and good morning, everyone. As Joe said, this was a strong quarter for CSW, highlighted by record results and significant progress integrating our recent acquisitions. I will cover our consolidated performance, segment results, cash flows, and our balance sheet. For the first quarter of fiscal 2027, consolidated revenue increased $87 million and reached a record $351 million, up 33% year-over-year.
Growth was primarily driven by the recent acquisitions with additional contribution from organic revenue growth. We are pleased to report consolidated organic revenue growth of 5.3%, coming from the Contractor Solutions and Specialized Reliability Solutions segments, as well as the businesses that will continue in Engineered Building Solutions following the exit of the Greco businesses. Adjusted gross margin was 45.1%, up 130 basis points from 43.8% in the prior year period, primarily due to favorable product mix as well as cost savings resulting from certain restructuring actions and synergies from our acquisitions. While there has been cost inflation in multiple raw material inputs, as well as in both ocean and domestic freight, we have been successful in offsetting these increases and continued tariff costs through recent price increases across our businesses.
Consolidated adjusted EBITDA for the fiscal first quarter was a record $102 million, up $33 million, or 48% from the prior year period, demonstrating the earnings power of our expanded product platform and improving market demand. Adjusted EBITDA margin expanded 290 basis points to 29%, supported by the contribution from recent acquisitions, strategic pricing actions, synergy and restructuring realization, and disciplined cost controls as we grow. These results highlight the scalability of our operating model and the margin opportunity embedded in our product portfolio.
Adjusted EPS for the fiscal first quarter was $3.84, up 35% from the same period last year. As we've communicated, EPS growth trailed EBITDA growth primarily due to higher interest expense, up $11.7 million, as we have a higher debt balance following the significant acquisition activity and share repurchases over the last year.
Turning to items excluded from adjusted EPS, the fiscal first quarter included, net of tax, $11.8 million or $0.72 per share of amortization of acquired intangible assets, and $1 million or $0.06 per share of acquisition-related integration costs. In Contractor Solutions, fiscal first-quarter revenue was $276 million, representing 78% of our consolidated revenue. The segment revenues increased by over 40% as compared to the prior year quarter.
Acquisitions contributed $68 million, or 34.4%, while organic growth contributed $11.6 million, or 5.9%. We are pleased to have delivered a second consecutive quarter of organic growth in Contractor Solutions, with contribution from both increased pricing and volumes. Organic growth in the quarter includes 2 months of Aspen sales due to last year's acquisition on May 1. Contractor Solutions adjusted EBITDA was $94 million with a 34.2% margin compared with $65 million or a 33% margin in the prior year period.
The year-over-year margin accretion primarily reflects favorable product mix, pricing actions, and partial synergy realization offset by raw materials and freight inflation. We are pleased to announce that our expectation for MARS Parts run rate cost synergies is now $13 million, exceeding our earlier estimates, and we have already achieved our 30% EBITDA margin goal for MARS in the last 2 quarters.
Specialized Reliability Solutions revenue increased 30.9% to $48 million, including $5.3 million, or 14.5% from acquisitions, and $6.1 million, or 16.5% from organic growth. Adjusted segment EBITDA in the first quarter was $10 million, up 54%. Adjusted EBITDA margin expanded 320 basis points to 20.8%, driven by higher-margin acquisitions, strategic pricing actions, and a favorable product mix. The integration of the 2 businesses acquired in the fiscal third quarter of 2026 continues to progress successfully.
In response to rising costs for certain petroleum-based inputs in the Specialized Reliability Solutions segment, we announced 3 separate price increases during the fiscal first quarter to offset the impact. We continue to monitor the situation very closely, and we will continue to take appropriate pricing action as needed. We continue to see solid demand momentum and resiliency to date, and the team has done an excellent job integrating the acquired businesses.
Within the Engineered Building Solutions segment, we previously announced our plan to sell the Greco U.S. business and strategically exit the Greco Canada business. But the Greco U.S. business was classified as held for sale as of March 31, 2026. We will continue to update our progress on these transactions as warranted on future earnings calls.
Excluding the Greco businesses, Engineered Building Solutions segment revenue was $23.4 million, up 7% over the prior year period. Segment adjusted EBITDA was $6.1 million, and adjusted EBITDA margin was 26.2%, compared with 17.5% in the prior year. The remaining EBS businesses are performing well, with a trailing 4 quarter book-to-bill ratio of 1.04:1, along with a record backlog supporting our confidence in solid margins going forward. We have transitioned to a 4 quarter metric due to the nature of the remaining businesses in this segment.
Turning to consolidated cash flows, we had an operating cash inflow of $76 million in the fiscal first quarter, compared with $61 million in the prior year quarter. The year-over-year increase primarily reflects the contribution from the acquisitions completed during fiscal 2026, despite the higher interest expense from increased outstanding borrowings. Free cash flows, defined as cash flows from operations less capital expenditures was an inflow of $70 million in the fiscal first quarter, compared with an inflow of $58 million in the prior year period.
Our effective tax rate for the fiscal first quarter was 25.6% on a GAAP basis. We expect amortization of intangible assets to be approximately $61 million for fiscal 2027. At quarter end, we had $858 million of debt outstanding across our revolving credit facility and the Term Loan A. Reflecting the higher debt balance compared to the prior year, interest expense during the fiscal first quarter of 2027 was $12.7 million, compared with $1 million in the prior year quarter. We currently estimate fiscal year 2027 interest expense of approximately $48 million.
This assumes no M&A or outsized share repurchase activity. At quarter-end, our net debt for covenant calculation purposes was $815 million, resulting in a net debt-to-EBITDA leverage ratio of 2.37x. This results in an interest rate of SOFR plus 200 basis points for both of our debt instruments. As a reminder, in the third quarter of fiscal 2026, we executed an interest rate swap to fix SOFR at 3.42% for 3 years to hedge $300 million of our Term Loan A balance. This swapped interest rate remains well below the current SOFR rate, generating interest expense savings.
We continue to maintain a strong balance sheet, with the net debt-to-EBITDA well within our target range of 1x to 3x. This provides ample liquidity to support growth initiatives and our other capital allocation priorities. Consistent with that philosophy, during the quarter, we repurchased approximately $23.5 million of our stock in the open market, representing 88,000 shares at an average price of $267 per share, which reiterates our confidence in our ability to create long-term shareholder value through disciplined capital allocation.
Overall, our outlook for fiscal 2027 remains positive. We expect all segments to show organic revenue growth and EBITDA growth versus the prior year, excluding the Greco businesses within the EBS segment, supported by resilient demand, acquisition contribution, synergy realization, and continued execution across all segments. At a consolidated level, we expect to see significant adjusted EBITDA and EPS growth in fiscal 2027.
Because GAAP EPS will reflect the full-year impact of higher interest expense and increased intangible amortization from our recent acquisitions, adjusted EBITDA remains the best measure of our underlying profitability growth and expanding earnings power of the business. We continue to expect to deliver strong free cash flows generation in fiscal 2027, with significant growth from the fiscal 2026 level. Finally, we still expect our fiscal year 2027 GAAP tax rate to be approximately 23% to 24% and the adjusted tax rate to be approximately 26%. Quarterly rates will vary based on specific items.
With that, I'll now turn the call back to Joe for closing remarks.
Joseph Armes - Chairman of the Board, President, Chief Executive Officer
Thank you, James. To summarize, CSW delivered an outstanding fiscal first quarter 2027 with revenue growth of 33%, expanding margins due to volume leverage, acquisition integration, and synergy realization. Our acquisitions are strengthening the overall business. Our teams are executing with discipline, and our portfolio is positioned to deliver sustainable, above-market, profitable growth. Our upcoming exit of the Greco business demonstrates our commitment to stewarding our portfolio efficiently and to the long-term value creation benefit of our shareholders.
As we move through fiscal 2027, our priorities are clear. Allocate capital with discipline, preserve balance sheet flexibility, deliver growth above the markets we serve, expand our profitability, and realize acquisition synergies. To reiterate, we expect full-year growth in organic revenue and significant growth in adjusted EBITDA, adjusted EPS, and free cash flows. Simultaneously, we will pursue accretive acquisitions that enhance our portfolio and strengthen our ability to serve our customers.
CSW takes great pride in being the partner of choice for our loyal customers, with the goal of making it as easy as possible to do business with us. Our Specialized Reliability Solutions segment was recently awarded the 2025 Lifecycle Business Unit Partner Supplier of the Year by Vermeer, who is an important customer, further exemplifying the outstanding customer service and operational execution of our team. And I want to recognize the Specialized Reliability Solutions team and its leader, Mark Bass, for this accomplishment.
As we often say at CSW, how we succeed matters. So we continue to focus on our most important asset, which is our people. And I'm pleased to report that CSW reported the safest calendar year first half since we began tracking safety metrics. Our prioritization of keeping team members safe on a daily basis has allowed us to achieve this milestone, and I want to thank every team member at CSW for contributing to our continued success and safety and reaching this meaningful win for the company.
Our employee-centric culture continues to be a competitive advantage for CSW. Not only do we offer our team members the opportunity to earn a safe, secure, and dignified retirement, but we also encourage the children of CSW employees to pursue educational opportunities, such as college degrees and trade school certification. Since 2018, CSW has awarded 57 grants worth $500,000 in the aggregate to the dependents of CSW employees. The scholarship program has historically supported first-generation college and vocational students and is named for the person who established it, who is our former Vice President of Human Resources, Mary Burns.
CSW Industrials recently granted 7 new scholarships for the upcoming academic year. We are proud to invest in the families of our employees. We hope these students feel affirmed in their ambitions and will be inspired to do great things. In closing, I want to thank our CSW Industrials team, who collectively own approximately 3% of the company, including our ESOP, for their continued performance and commitment. I also want to thank you, our shareholders, for your continued interest and support of CSW Industrials.
Now, Julian, we're ready to open the line for questions.

Thank you. We will now be conducting a question-and-answer session. (Operator Instructions)
Jon Tanwanteng, CJS Securities.
Jonathan Tanwanteng - Analyst
This is actually Jeremy on for Jon. Congrats on the great quarter, guys. Can you just talk about how your recent acquisitions have been performing versus expectations, especially MARS and Aspen, given the exposure to more repair activity?
Joseph Armes - Chairman of the Board, President, Chief Executive Officer
Yes, I'll start, Jeremy. This is Joe. We're very pleased with both of those acquisitions. I think that the integrations have gone very well. Our team has done a great job working through that. We're extremely pleased with the customer reaction that we've received of our addition of those lines of business, those product lines, into our systems and making -- again, making it easy for our wholesale distribution customers to do business with us to get these products on time, orders in full when they need it so that they don't miss sales during the busy season here. So overall, really very, very pleased with the way those have gone and especially with the customer reaction.
James Perry - Chief Financial Officer, Executive Vice President
Yes, I would just add. Both have gone through very successful ERP conversions, MARS back in January, Aspen during this last fiscal quarter. I mentioned in my remarks, Jeremy, that we've got $13 million of synergies we've talked about publicly now up from the original $10 million that we put in the original M&A press release. We've also hit the 30% EBITDA number, two quarters in a row. So we've kind of already hit the targets that we put out there for later this year. So that's behind us, and we can just continue to work on serving our customers well. But yes, both have gone very well.
Jonathan Tanwanteng - Analyst
Could you just talk a little bit more to how trends are looking heading into fiscal quarter two in terms of demand and channel inventory?
James Perry - Chief Financial Officer, Executive Vice President
Yes, this is James. I would say, in general, we continue to feel very positive about that. June had good results, at least from one of the industry sources that just came out in recent days. That was positive. So that's good to see. As I'm sure most folks on the call would know, it's gotten hot most places around the country. And when it gets hot everywhere and stays consistently hot a lot of places, air conditioners are working a lot harder. People are turning them on.
Number one can lead to repair, obviously, and we have exposure to that now that we didn't really have before the Aspen and MARS acquisitions. Now we touch that part of the market. And then that leads to replacement at some point. And obviously, we have a big place in replacement, as we always have. So I think from that perspective, we continue to see nice demand from our customers and the ultimate customer, the homeowner.
In terms of channel inventories, I think the general sense we have and not just in one-off conversations, but the metrics we've seen out there, the channel inventories, as we said, last year's overhang, the back part of the year, got kind of resolved through the regular buying season this year, and things are in a good place. We feel good about where that is vis-a-vis our customers and their inventory and what their expectations for needs the rest of the season are.
Jonathan Tanwanteng - Analyst
Great. Thank you, guys, and congrats again. Thank you, Jeremy.

Good morning. This is Ethan on for Tomo. And congrats on the safest calendar year in first half history. Congratulations.
Joseph Armes - Chairman of the Board, President, Chief Executive Officer
Proud of that.
Unidentified Participant
And it's encouraging to see volume growth returning this quarter in CS. Did CSW happen to see any pre-buying within the quarter? And do you -- how do you see the end markets performing, specifically like breaking out like new construction, repair, and then like replacement as well?
James Perry - Chief Financial Officer, Executive Vice President
Yes, Ethan, it's James. Thanks for your safety comments. That's very important to us, and I know it is to you guys as well, so thank you for that. I don't think we saw unusual pre-buying. We've had some price increases off and on throughout the year across the board, but it hasn't led to anything unusual. So I don't think you saw anything accelerated into the June quarter in any of our business segments that would take away from now our July, August, September quarter. So nothing unusual there.
And again, as we said, demand across the board, we feel good about that. Order rates have been good. We're well into July now and we feel good about that. Across the board, we mentioned a record backlog in EBS exiting the June quarter. So we've found the right pockets of that market, which can be pretty volatile. Of course, Commercial construction is still soft with ABI and Dodge Momentum and those type of indices, but our team has done a great job finding the right jobs.
Mark Bass's group, Joe called him out specifically, well deserved, that group, with an over 20% margin, continues to perform very well in their order taking and meeting customer demand, doing a great job there with some good momentum there. You know, the energy markets tend to create demand with these kind of prices. You see more of that, and that's been a tailwind to them. But they've done a great job overall in integrating the acquisitions as well and then finding new customers and those type things. And then, as I mentioned earlier, within Contractor Solutions, I think with the hot weather we see, with inventory levels getting back in a good place earlier this year, we're seeing nice momentum there as well.
Unidentified Participant
Thank you. And then on EBS, the margin profile excluding Greco was up like 180 basis points year-over-year. Is it safe to assume that this kind of level of mid-20s percent margin is achievable for the rest of the year and into -- potentially in the future?
James Perry - Chief Financial Officer, Executive Vice President
Yes, Ethan, yes, I appreciate you noticing that. Yes, you had some good projects closed in the quarter, and that margin was a little higher than normal. We've talked about a 20% kind of margin going forward. It's going to bounce around as we go through the backlog. You're obviously still delivering some things in the backlog with better margins than others, given some of the commodity costs. Yes, so you had a really good margin quarter, up quite a bit over last year, 17.5% last year, 26.2% this year.
But I think for us to continue to keep that kind of 20-plus percent margin target in this tough market for the full fiscal year is still appropriate. It's going to bounce around a little. Longer term, I think the opportunity to be well within the 20s is there. But again, in this market right now, the team is doing a good job finding projects they can to fill the facilities and delivering those projects.
We'll have a little bit faster turn of projects in the 2 remaining businesses. That's why we moved to a 4 quarter book-to-bill type ratio. That was above 1:1, so that's very positive. So they're seeing some nice momentum, but I wouldn't model mid-20s yet that we're probably a ways from being able to commit to something like that.
Unidentified Participant
Thank you so much.
James Perry - Chief Financial Officer, Executive Vice President
Thanks, Ethan.
Operator
Tim Wojs, Baird.
Timothy Wojs - Analyst
Hey guys, good morning. Nice job. Good morning. Thanks. Maybe just the first question. I hopped on late, unfortunately. So I'm sorry if this is a repeat. Is there any kind of color you can give us on just some of the top line -- if there's been any top line contribution from bringing MARS and Aspen into this organization and kind of cross-selling, you know, that broader portfolio? Or is that still kind of subdued here in the near term and still kind of an opportunity on a go-forward basis? Just trying to understand if you're already seeing some benefits from that on the top line.
James Perry - Chief Financial Officer, Executive Vice President
Yes, I would say yes and yes, Tim. I think we've certainly seen some contribution. This is now our second full season with Aspen. There wasn't a lot of that conversion last year, but the team's doing a good job cross-selling to our existing customers now that we're in kind of season 2 of owning the Aspen business. MARS, we got converted over to the ERP in January, as you know, to better serve our existing customers. I think we're seeing a little bit of that. Jeff's team has done a great job with that. But we would certainly tell you that there's opportunity for that to continue to grow.
As you well know, you try to convert what you can year 1 and year 2, but you see conversions year 3, 4, and 5. We've got so many product categories. It takes a while for some of our customers to turnover inventory they may have of a competitor's product. So we're getting some nice wins. Our growth includes wins of new business, obviously, having that acquisition growth and organic growth both. So we're going to continue to see that as a tailwind, I think, going forward. But yes, you've got some contribution, but more to come.
Timothy Wojs - Analyst
Okay, great. And then when we think about just kind of the timing of input cost inflation, is Q1 kind of representative of kind of the price cost cadence you'd expect this year? Or do you see some kind of higher inflation kind of creeping up through the rest of the year -- at least the rest of the calendar year?
James Perry - Chief Financial Officer, Executive Vice President
Yes, good question, Tim. It's bounced around. Obviously, we clearly know that our ocean freight was up quite a bit -- came down quite a bit, up quite a bit since the issues in the Middle East, of course. That's made shipping rates quite a bit elevated. You've seen a little relief there over the last couple of weeks, so that's encouraging, but we'll wait and see if that's a trend.
Domestic, our team's done a great job within Contractor Solutions with the trucking business, bringing the logistics side of that in-house, not owning the assets, but managing the shipping lanes and so forth. They found some nice savings, but that's been eaten up by higher diesel costs. So that's in there. And as you know, it takes a little while for that to flow through the system, just given how things flow through the cost of goods sold.
Obviously, trucking is a little quicker than things like inflation of steel, aluminum, plastic costs have obviously gone up. Yes, but those started to spike, as you said, back in the spring. So you're seeing that coming through now already. Our Contractor Solutions team raised prices, ranging from about 3% to 5%, depending on the product, back at the beginning of July. So you didn't have the price impact of that in the June quarter. We had our normal price increase back in January, so you had that tailwind. But we really just put the price increase in place in July to cover some of those other costs that were elevated.
As we often say, we don't raise prices the minute that we see costs go up. We're patient to watch what it is, but we don't wait to the last minute either. We make sure that it's a disciplined approach. We give our customers plenty of notice. We make sure that we get ahead of it, running through cost of goods sold where we can. And the team has done a great disciplined job of that, of balancing what we need to pass through from an inflationary standpoint. And in terms of what we're going to see going forward, we can't predict what some of those costs are, but we have a good sense at least what's in cost of goods sold. And most of it's been relatively steady now the last few weeks and couple months that we kind of see what's in the inventory.
Timothy Wojs - Analyst
Okay, great. And then this is kind of a nuanced question, but I think it's a little bit important. If I remember, I think Aspen had a really good quarter last year in kind of the September quarter. You know, that was kind of inorganic growth, and now it's going to get folded into organic growth. So is that -- should we be mindful of that? Is that going to potentially be an organic kind of growth headwind in the second quarter, just kind of given those, I guess, kind of accounting dynamics?
James Perry - Chief Financial Officer, Executive Vice President
Yes, it could be, Tim. I think it's a great point. You've got MARS as well now from the overall base, so you have a bigger base, but that's not going to be organic until November. Yes, Aspen had a great year last year, so the comps are a little bit tough. The selling season came a little bit earlier last year because of the refrigeration change and the canister issues and some of those things. So they had a tough June comp as well. So the June and September quarters for Aspen were really good last year. Part of that was price-based just because the cost of that refrigerant had gone up, and that's kind of come back to normal for the most part now that the industry's over that hump.
So, yes, you've got a little bit of a headwind there. I think that's good, but I think we still feel good. As Joe said, we still feel good about organic growth across all segments for the year. But, yes, it's good for you to remember that, and we'll remind people of that. It's a little early in the quarter to give specific feedback there. But, yes, Aspen had a really good year last year, but is pleased with how they're performing this year as well.
Timothy Wojs - Analyst
Okay, great. Well, nice job. I'll hop back in queue. Thanks.

Sam Ried, Wells Fargo.
Unidentified Participant
This is Eric on for Sam. Congrats on a good quarter. I want to ask about SRS. You had really strong organic growth, highest in, looks like, a few years, and really strong acceleration. Just curious if there's anything, sort of outsized impact in Q1 that is sustainable going forward, or if there's any pull forward into Q1 from the later quarters?
James Perry - Chief Financial Officer, Executive Vice President
I wouldn't say, Eric -- this is James. Thanks for being on. Nothing unusual. Team is doing a great job. I mean, they're really finding the demand out there, really -- praise the team out there and doing a good job. As I mentioned earlier, when energy prices are elevated, you get a bit of a tailwind there because there's more of that going on and there's a segment of our business that's indexed to that, that gets a favorable tailwind from that perspective. We talked about energy being a bit of a natural hedge. When inflation caused some of our input costs to go up, we pushed that through in pricing, but it also creates a tailwind in demand because people are producing more energy and so forth globally. So that's a good thing.
The things were, as you said, a little softer last year. So the comp helped a little bit. But overall, I wouldn't say there's anything terribly unusual. There weren't any one-offs. There wasn't a big, someone earlier asked about pre-sales. It wasn't that. We had a price increase May 1, June 1, and July 1, and we didn't really see exceptional buys ahead of those price increases. So really just good job finding orders and great job executing, getting things out the door.
Sam Reid - Analyst
That's great. And just on SG&A, it was very well managed and you called out lower operating expenses. Just curious where you're finding the cost-saving opportunities and sort of how sustainable is the SG&A margin at this level or sort of where do you think you can get additional opportunities?
James Perry - Chief Financial Officer, Executive Vice President
Yes, one thing I would say, and I'll let Joe add if he wants to, we've got a bit of a commitment internally that as we grow, we don't need to add as much SG&A. We're starting to really see some economies of scale with the $1 billion we invested in acquisitions last year, and we don't need to add a whole lot of folks to manage that. Joe?
Joseph Armes - Chairman of the Board, President, Chief Executive Officer
No, it's a really important part of the acquisition algorithm for value creation here is that -- and we talk a lot about the volume leverage, but that has a cost component. And we have to be mindful of costs creeping up, and we are very vigilant in trying to make sure that these shareholders get every bit of benefit out of these acquisitions that they should get. So, it's a great question. Glad you asked because I think the cost containment has been a little bit of an underappreciated part of the story here. But yes, top line growth provides the opportunity for operating leverage. And so the cost containment is a key part of really realizing that.
Operator
Susan Maklari, Goldman Sachs.
Susan Maklari - Analyst
Good morning, everyone. My first question is on the supply chain. Can you give us an update on the efforts there to move some of your production to Vietnam? And then I guess with that, just talk generally to the impact of tariffs and anything that's changed from that perspective?
James Perry - Chief Financial Officer, Executive Vice President
Sure, so this is James. Yes, we continue to move things as we can into Vietnam, and Thailand is another good home for us right now. We've talked about as we make acquisitions, they tend to have a little more in China, so we take a step backwards and then a step forward, so we're doing a great job.
Overall, we continue to be around those same numbers. Vietnam is kind of in the low 30s as a percent of cost of goods sold as we look at this fiscal year, kind of going forward where we're targeting within Contractor Solutions. The U.S. is about 45% to 50% or so. Thailand is upper single digits, and then you got a little string around here and there. China is around 10%. So we keep hovering around that 10%. The goal is to continue to take that down, but again, acquisitions tend to have some of that and we've done a good job.
We've talked about -- we've even got some folks that have set up their own shops within Vietnam from other countries because it's a favorable place to do business and we've helped them do that. So it's not always just moving into our own facility there in Vietnam. So I think the team has done a good job. The numbers haven't moved dramatically. And part of that is, again, just getting some of the acquisition-related supply chain out of China. But the team has done a great job, and we're very comfortable where we are.
In terms of tariffs, things have been relatively stable. You know, the HVAC part has got a little bit of relief, and so that helped us. It helped us keep down that most recent price increase we put in early July, having that benefit, knowing that those tariffs were going to be helped a little bit. The most recent tariff activity last Friday really just replaced what was there before. The 10% goes to either 10% or 12%, depending on where you are.
So some of the things are not impacted by that at all because they're under a different tariff structure. So some of our parts coming out of Vietnam and other places are not impacted by that. So there was no change as a result of that. So on the whole, the last few months have been relatively stable from a tariff perspective, Sue.

Okay, alright, that's very helpful color. And then maybe turning to the M&A pipeline, can you just talk about what you're seeing there, your appetite for some smaller deals, especially as you've hit some of your key hurdles with Aspen and MARS, and then how we should also just be thinking about other priorities for capital allocation?
Joseph Armes - Chairman of the Board, President, Chief Executive Officer
Sure. No, it's a great question, Sue, and this is Joe. We continue to see a number of opportunities -- I feel like we're seeing all of the opportunities that are reasonable for us to see. And as I think we've talked about 10 years ago, that wasn't the case. We were small. We didn't have a track record of success in doing acquisitions and integrating them successfully, and now we do. And so we see most every opportunity that I think we should see, which is really good. Our rigor and analysis and our discipline and investment continues to be a real focal point for us.
But yes, there is a nice pipeline, robust pipeline, of smaller deals in particular right now that we've been analyzing and evaluating. And as you noted, we needed a little bit of digestion period here with these larger acquisitions. I feel like we're largely through that. The success of the team and continued kind of performance on integrating well gives us even higher level of confidence in our ability to continue to do that going forward.
So, as we think about capital allocation broadly, the rubric remains the same. I mean, we are going to evaluate everything on risk-adjusted returns. And I will tell you, for the past quarter, the most attractive risk-adjusted return was to invest in our own stock. And so that's what you saw. It's what we've done. We've paid down some debt as well. There's a nice return on that. So all options remain open to us, and we'll continue to invest in the highest risk-adjusted return opportunities.
Susan Maklari - Analyst
Okay, that's great colors. Thank you, and good luck with the quarter.
Joseph Armes - Chairman of the Board, President, Chief Executive Officer

Andrew Kaplowitz - Analyst
Good morning, everyone. So, James, just back to MARS for a second. I think you've talked previously that there's a tradeoff between your core Contractor Solutions business and MARS that you're working on in terms of who's got the best products and which ones you're going to focus on. So has that continued to happen? And I didn't catch MARS growth, did you disclose that? Was it still negative in the quarter or did it turn?
James Perry - Chief Financial Officer, Executive Vice President
Yes, let me first address the first part. The team has done a great job with the product rationalization work that they've been going through. They've done that for the most part. They've picked the best product from kind of each category. As we've said, at times we pick a product that's got maybe a lower cost base and push it through our distribution network. Our customers have received that very well. So we're really pleased with that.
We did not give specific MARS performance. Now that it's pretty fully integrated within Contractor Solutions, it'll become organic in a few months, but we didn't break that or Aspen out anymore. That's kind of behind us. We did talk about the $13 million of synergies that we're seeing now, up from the original $10 million. We've talked about we've already hit the 30% EBITDA margin target, two quarters in a row ahead of schedule. So we're pleased with that. So, yes, we're not breaking out the specifics anymore. Now it's just really so well integrated, it's part of the segment.
Andrew Kaplowitz - Analyst
Helpful, I mean, I think last quarter, you talked about not taking price increases in Contractor Solutions and then, of course, you just told us that you took them in July, but you still grew EBITDA margin in Contractor Solutions in Q1 even without them.
We talked about fluctuating freight and commodity costs, so I know you don't want to get specific forward guidance, but can you continue to grow Contractor Solutions, EBITDA margin over the next few quarters, given sort of the puts and takes with the price and the inflation that we've talked about?
James Perry - Chief Financial Officer, Executive Vice President
Yeah, we had the price in July, which really covered what we need to do for inflation. So that's usually not a margin enhancement. We kind of work over time to get that back. When we do mid-year price increases, that's really kind of neutral from a dollar perspective. And in fact, it can be a tiny bit of a headwind to margin for a little while. And we work to get that back over time with our annual price increase as appropriate or finding ways to cut costs. The team is always looking to do that as well.
The 34% margin, very pleased with that. Obviously, Mars getting well above the 30% number now. We're pleased with that. That's a contributor. That wasn't in the portfolio a year ago. Aspen was there a year ago. And Aspen is a bit diluted to that just given the nature of the business. So I don't think we would commit to margin expansion necessarily. As the summer month is going to be the best margin. So quarter-to-quarter, things are going to fluctuate.
Kind of the quarter we just finished in the one we're in or the high water mark for margin and then. Have your lower margin kind of dip in December and then start recovering in March. So we've always said being in the low 30s is premier industry-wide margins. We've grown that overtime, but we've always said that if we can grow the top-line and maintain these margins, we'll be thrilled. So very pleased with the quarter that the team put together, the goal is to continue to produce good margins. But yeah, to your point, not giving guidance, I don't think we'll commit to where these margins are going forward or the ability to grow necessarily, but we're very pleased with the performance there.

Joseph Armes - Chairman of the Board, President, Chief Executive Officer
Thank you, Alexa, and good morning, everyone.
The exceptional fiscal first quarter results we reported today demonstrate the power of a disciplined capital allocation strategy laser-focused on growing shareholder value through market cycles.
We are reporting all-time record revenue, adjusted EBITDA, adjusted earnings per diluted share and operating cash flows due to the resilience of our businesses. The efficiency of our operations, and the successful integration of our recently completed acquisitions.
Guided by our enduring capital allocation strategy, since May 1 of 2025, we have invested approximately $1 billion to consummate five highly accretive and synergistic acquisitions, including the transformative additions of Mars parts.
And Aspen Manufacturing, plus three smaller but still immediately accretive acquisitions across our contractor solutions and our specialized reliability solutions segments.
As I mentioned earlier, the integration of each of these businesses has gone very well.
Simultaneously, we have continued to return meaningful capital to shareholders.
During the quarter, CSW returned a total of $28.4 million in cash to shareholders through $23.5 million of open market share repurchases and $4.9 million in dividends.
Our continued investment in our own shares demonstrates our strong belief that our equity has been undervalued relative to our growth and profitability and cash flows, thus representing a compelling investment opportunity.
Concurrently with our share repurchases, we also delevered during the quarter, reducing our net debt-to-EBITDA ratio. From 2.55 times at fiscal 2026 year end to 2.37 times at the end of the fiscal first quarter through the reduction of net debt plus growth in our EBITDA.
Our balance sheet strength gives us the flexibility to exploit all capital allocation alternatives open to us.
End market momentum remained constructive despite the various dynamics in the macroeconomic environment during the quarter.
All three of our business segments generated strong top-line results accompanied by margin expansion.
Our Contractor Solutions segment is growing and expanding margins, benefiting greatly from the comprehensive product offering created by the addition of MARS and Aspen. We are positioned to serve our customers well as we move through peak cooling season.
We continue to expect this segment to outgrow the end market served, which would result in mid to high single-digit organic growth through the cycle.
Our specialized reliability solutions segment delivered robust organic revenue growth. With an EBITDA margin in excess of the 20% target that we have for this segment.
The integration of the two recent acquisitions continues to provide accretion, and we expect to show continued margin strength for the full fiscal year.
We continue to work toward the exit of the Greco business in our engineered building solutions segment.
Excluding the Greco business, the segment generated organic revenue growth, a strong EBITDA margin, and we exited the quarter with record order backlog, reinforcing our confidence in the segment's outlook and margin trajectory.
At this time, I will turn the call over to James for a detailed review of our financial performance, and then I will return afterward with a few closing comments.
James Perry - Chief Financial Officer, Executive Vice President
Thank you, Joe, and good morning, everyone.
As Joe said, this was a strong quarter for CSW, highlighted by record results and significant progress integrating our recent acquisitions.
I will cover our consolidated performance, segment results, cash flows, and our balance sheet.
For the first quarter of fiscal 2027, consolidated revenue increased $87 million and reached a record $351 million, up 33% year over year.
Growth was primarily driven by the recent acquisitions with additional contribution from organic revenue growth.
We are pleased to report consolidated organic revenue growth of 5.3% coming from the Contractor Solutions and Specialized Reliability Solutions segments, as well as the businesses that will continue in Engineered Building Solutions following the exit of the Greco businesses.
Adjusted gross margin was 45.1%.
Of 130 basis points from 43.8% in the prior year period, primarily due to favorable product mix, as well as cost savings resulting from certain restructuring actions and synergies from our acquisitions.
While there has been cost inflation in multiple raw material inputs, as well as in both ocean and domestic freight, we have been successful in offsetting these increases and continued tariff costs through recent price increases across our businesses.
Consolidated adjusted EBITDA for the fiscal first quarter was a record $102 million, up $33 million or 48% from the prior year period, demonstrating the earnings power of our expanded product platform and improving market demand.
Adjusted EBITDA margin expanded 290 points to 29%, supported by the contribution from recent acquisitions, strategic pricing actions. Synergy and restructuring realization and disciplined cost controls as we grow.
These results highlight the scalability of our operating model and the margin opportunity embedded in our product portfolio.
Adjusted EPS for the fiscal first quarter was $3.84, up 35% from the same period last year.
As we've communicated, EPS growth trailed EBITDA growth primarily due to higher interest expense. Up $11.7 million as we have a higher debt balance following the significant acquisition activity and share repurchases over the last year.
Turning to items excluded from adjusted EPS, the fiscal first quarter included net of tax, $11.8 million or $0.72 per share of amortization of acquired intangible assets and $1 million or $0.06 per share of acquisition-related integration costs.
In Contractor Solutions, fiscal first quarter revenue was $276 million, representing 78% of our consolidated revenues.
The segment revenues increased by over 40% as compared to the prior year quarter.
Acquisitions contributed $68 million or 34.4%, while organic growth contributed $11.6 million or 5.9%.
We are pleased to have delivered a second consecutive quarter of organic growth in Contractor Solutions with contribution from both increased pricing and volumes.
Organic growth in the quarter includes two months of Aspen sales due to last year's acquisition on May 1.
Contractor Solutions adjusted EBITDA was $94 million with a 34.2% margin. Compared with $65 million or a 33% margin in the prior year period.
The year-over-year margin accretion primarily reflects favorable product mix, pricing actions, and partial synergy realization offset by raw materials and freight inflation.
We are pleased to announce that our expectation for Mars Parts run rate cost synergies is now $13 million, exceeding our earlier estimates. And we have already achieved our 30% EBITDA margin goal for Mars in the last two quarters.
Specialized Reliability Solutions revenue increased 30.9% to $48 million, including $5.3 million or 14.5% from acquisitions and $6.1 million or 16.5% from organic growth.
Adjusted segment EBITDA in the first quarter. Was $10 million, up 54% and adjusted EBITDA margin expanded 320 basis points to 20.8%, driven by higher margin acquisitions, strategic pricing actions and a favorable product mix.
The integration of the two businesses acquired in the fiscal third quarter of 2026 continues to progress successfully.
In response to rising costs for certain petroleum-based inputs in the specialized reliability solutions segment, we announced three separate price increases during the fiscal first quarter to offset the impact.
We continue to monitor the situation very closely, and we will continue to take appropriate pricing action as needed.
We continue to see solid demand momentum and resiliency to date, and the team has done an excellent job integrating the acquired businesses.
Within the Engineer Building Solutions segment, we previously announced our plan to sell the Greco US business and strategically exit the Greco Canada business.
The Greco US business was classified as held for sale as of March 31, 2026.
We will continue to update our progress on these transactions as warranted on future earnings calls.
Excluding the Greco businesses. Engineered Building Solutions segment revenue was $23.4 million, up 7% over the prior year period.
Segment adjusted EBITDA was $6.1 million and adjusted EBITDA margin was 26.2% compared with 17.5% in the prior year.
The remaining EBS businesses are performing well with a trailing four-quarter book-to-bill ratio of 1.04 to 1 along with a record backlog.
Supporting our confidence in solid margins going forward.
We have transitioned to a four-quarter metric due to the nature of the remaining businesses in this segment.
Turning to consolidated cash flows, we had an operating cash inflow of $76 million in the fiscal first quarter, compared with $61 million in the prior year quarter.
The year-over-year increase primarily reflects the contribution from the acquisitions completed during fiscal 2026, despite the higher interest expense from increased outstanding borrowings.
Free cash flows, defined as cash flows from operations less capital expenditures, was an inflow of $70 million in the fiscal first quarter, compared with an inflow of $58 million in the prior year period.
Our effective tax rate for the fiscal first quarter was 25.6% on a GAAP basis.
We expect amortization of intangible assets to be approximately $61 million for fiscal 2027.
At quarter end, we had $858 million of debt outstanding across our revolving credit facility in the term loan aid, reflecting the higher debt balance compared to the prior year. Interest expense during the fiscal first quarter of 2027 was $12.7 million compared with $1 million in the prior year quarter.
We currently estimate fiscal year 2027 interest expense of approximately $48 million.
This assumes no M&A or outsized share repurchase activity.
At quarter end, our net debt for covenant calculation purposes was $815 million, resulting in a net debt to EBITDA leverage ratio of 2.37 times.
This results in an interest rate of SOFR plus 200 basis points for both of our debt instruments.
As a reminder. In the third quarter of fiscal 2026, we executed an interest rate swap to fix SOFR at 3.42% for three years to hedge $300 million of our term loan A balance.
This swapped interest rate remains well below the current SOFR rate, generating interest expense savings.
We continue to maintain a strong balance sheet with a net debt to EBITDA well within our target range of one to three times.
This provides ample liquidity to support growth initiatives and our other capital allocation priorities.
Consistent with that philosophy, during the quarter, we repurchased approximately $23.5 million of our stock in the open market, representing 88,000 shares at an average price of $267 per share, which reiterates our confidence in our ability to create long-term shareholder value through disciplined capital allocation.
Overall, our outlook for fiscal 2027 remains positive.
We expect all segments to show organic revenue growth and EBITDA growth versus the prior year, excluding the Greco businesses within the EBS segment, supported by resilient demand, acquisition contribution, synergy realization and continued execution across all segments.
At a consolidated level, we expect to see significant adjusted EBITDA and EPS growth in fiscal 2027.
Because GAAP EPS will reflect the full year impact of higher interest expense and increased intangible amortization from our recent acquisitions, adjusted EBITDA remains the best measure of our underlying profitability growth and expanding earnings power of the business.
We continue to expect to deliver strong free cash flows generation in fiscal 2027. With significant growth from the fiscal 2026 level.
Finally, we still expect our fiscal year 2027 GAAP tax rate to be approximately 23% to 24% and the adjusted tax rate to be approximately 26%. Quarterly rates will vary based on specific items.
With that, I'll now turn the call back to Joe for closing remarks.
Joseph Armes - Chairman of the Board, President, Chief Executive Officer
Thank you, James.
Summarize, CSW delivered an outstanding fiscal first quarter 2027 with revenue growth of 33%, expanding margins due to volume leverage, acquisition integration, and synergy realization.
Our acquisitions are strengthening the overall business. Our teams are executing with discipline.
And our portfolio is positioned to deliver sustainable, above-market, profitable growth.
Our upcoming exit of the Greco business demonstrates our commitment to stewarding our portfolio efficiently and to the long-term value creation benefit of our shareholders.
As we move through fiscal 2027, our priorities are clear.
Allocate capital with discipline, preserve balance sheet flexibility, deliver growth above the markets we serve, expand our profitability and realize acquisition synergies.
To reiterate, we expect full-year growth in organic revenue and significant growth in adjusted EBITDA, adjusted EPS, and free cash flows.
Simultaneously, we will pursue accretive acquisitions that enhance our portfolio and strengthen our ability to serve our customers.
CSW takes great pride in being the partner of choice for our loyal customers, with the goal of making it as easy as possible to do business with us.
Our Specialized Reliability Solutions segment was recently awarded the 2025 Lifecycle Business Unit Partner Supplier of the Year by Vermeer, who is an important customer, further exemplifying the outstanding customer service and operational execution of our team. And I want to recognize the Specialized Reliability Solutions team and its leader, Mark Bass, for this accomplishment.
As we often say at CSW, how we succeed matters. So we continue to focus on our most important asset, which is our people. And I'm pleased to report that CSW reported the safest calendar year first half since we began tracking safety metrics.
Our prioritization of keeping team members safe on a daily basis has allowed us to achieve this milestone. And I want to thank every team member at CSW for contributing to our continued success and safety and reaching this meaningful win for the company.
Our employee-centric culture continues to be a competitive advantage for CSW.
Not only do we offer our team members the opportunity to earn a safe, secure and dignified retirement. But we also encourage the children of CSW employees to pursue educational opportunities such as college degrees and trade school certifications.
Since 2018, CSW has awarded 57 grants worth $500,000 in the aggregate to the dependents of CSW employees.
The scholarship program has historically supported first generation college and vocational students. Is named for the person who established it, who is our former Vice President of Human Resources, Mary Burns.
CSW Industrials recently granted seven new scholarships for the upcoming academic year. We are proud to invest in the families of our employees. We hope these students feel affirmed in their ambitions and will be inspired to do great things.
In closing, I want to thank our CSW Industrials team who collectively own approximately 3% of the company, including our ESOP, for their continued performance and commitment.
I also want to thank you, our shareholders, for your continued interest and support of CSW Industrials.
Now, Julian, we're ready to open the line for questions.

One moment while we pull for questions.
And our first question comes from the line of John Tanwateng with CJS Securities. Please proceed with your question.
Jonathan Tanwanteng - Analyst
It's actually Jeremy on for John. Congrats on a great quarter, guys.
Joseph Armes - Chairman of the Board, President, Chief Executive Officer
Thank you.
Jonathan Tanwanteng - Analyst
Of course. Can you just talk about how your recent acquisitions have been performing versus expectations, especially Mars and Aspen, given the exposure to more repair activity?
Joseph Armes - Chairman of the Board, President, Chief Executive Officer
Yeah, I'll start, Jeremy. This is Joe. We're very pleased with both of those acquisitions.
I think that the integrations have gone very well. Our team has done a great job working through that. We're extremely pleased with the customer reaction that we've received of our addition of those lines of business, those product lines into our.
Systems and making, again, making it easy for our wholesale distribution customers to do business with us to get these products on time, orders in full when they need it so that they don't miss sales during the busy season here. So overall, really very pleased with the way those have gone and especially with the customer reaction.
James Perry - Chief Financial Officer, Executive Vice President
Yeah, we just had both have gone through very successful ERP conversions, Mars back in January, Aspen during this last fiscal quarter. I mentioned in my remarks, Jeremy, that we've got $13 million of synergies we've talked about publicly now up from the original $10 million that we put in the original M&A press release. We've also hit the 30% EBITDA number two quarters in a row. So we kind of already hit the targets that we put out there. For later this year, so that's behind us and we can just continue to work on serving our customers well, but yes, both have gone very well.
Jonathan Tanwanteng - Analyst
Great, and then could you just talk a little bit more to how trends are looking heading into fiscal quarter two in terms of demand and channel inventory?
James Perry - Chief Financial Officer, Executive Vice President
Yeah, this is James. I would say, in general, we continue to feel very positive about that. June had good results, at least from one of the industry sources that just came out in recent days. That was positive. So that's good to see.
As I'm sure most folks on the call would know, it's gotten hot most places around the country. And when it gets hot everywhere and stays consistently hot a lot of places, air conditioners are working a lot harder. People are turning them on.
Number one can lead to repair, obviously, and we have exposure to that now that we didn't really have before the Aspen and Mars acquisitions, now we touch that part of the market and then that leads to replacement at some point and obviously, we have a big place in replacement as we always have. So I think from that perspective, we continue to see nice. Nice demand from our customers and the ultimate customer, the homeowner. In terms of channel inventories, I think the general sense we have and not just in one-off conversations, but the metrics we've seen out there, the channel inventories, as we said, last year's overhang, the back part of the year got kind of resolved through the regular buying season this year and things are in a good place. We feel good about where that is vis-a-vis our customers and their inventory and what their expectations for needs the rest of the season are.
Jonathan Tanwanteng - Analyst
Great.
Thank you guys and congrats again.
Operator
Thank you, Jeremy.
Thank you.
And our next question comes from the line of Tomo Osado with JP Morgan. Please proceed with your question.
Unidentified Participant
Good morning. This is Ethan on for Tomo and congrats on the safest calendar year and first half history. Congratulations.
Thank you very much. I appreciate that.
James Perry - Chief Financial Officer, Executive Vice President
I'm proud of that.
Unidentified Participant
And it's encouraging to see volume growth returning this quarter in CS. Did CSW happen to see any pre-buying within the quarter? And how do you see the end markets performing specifically like breaking out like new construction repair and then like replacement as well?
James Perry - Chief Financial Officer, Executive Vice President
Ethan, it's James. Thanks for your safety comments. That's very important to us and I know it is to you guys as well, so thank you for that.
I don't think we saw unusual pre-buying. We've had some price increases off and on throughout the year across the board, but it hasn't led to anything unusual. So I don't think you saw anything accelerated into the June quarter in any of our business segments that would take away from now our.
July, August, September quarter, so nothing unusual there. And again, as we said, demand across the board, we feel good about that. Order rates have been good. We're well into July now, and we feel good about that across the board. We mentioned a record backlog in EBS exiting the June quarter. So we've found the right pockets of that market, which can be pretty volatile. Of course, commercial construction is still soft with ABI and Dodge momentum and those type of indices, but our team has done a great job finding the right jobs.
Mark Bass' group, Joe called him out specifically, well deserved that group with an over 20% margin, continues to perform very well in their order taking and meeting customer demand.
Doing a great job there with some good momentum there. The energy markets tend to create demand with these kind of prices, you see more of that and that's been a tailwind to them, but they've done a great job overall and integrating the acquisitions as well and finding new customers and those type of things. And then as I mentioned earlier, within Contractor Solutions, I think with the hot weather we see with inventory levels getting back in a good place earlier this year, we're seeing nice momentum there as well.
Unidentified Participant
Thank you, and then on EBS, the margin profile excluding Greco was up like 180 basis points year-over-year, is it that this kind of level of mid-20s percent margin is achieved the rest of the year and into potentially in the future?
James Perry - Chief Financial Officer, Executive Vice President
Ethan, yeah, I appreciate you noticing that. Yeah, you had some good projects close in the quarter and that margin was a little higher than normal. We've talked about a 20% kind of margin going forward. It's going to bounce around as we go through the backlog. You're obviously still delivering some things in the backlog with better margins than others given some of the commodity cost. Yeah, so you had a really good margin quarter, up quite a bit over last year, 17.5% last year, 26.5% this year. But I think for us to continue to keep that kind of 20-plus percent.
Margin target in this tough market for the full fiscal year is still appropriate. It's going to bounce around a little. In longer-term, I think the opportunity to be well within the 20s is there. But again, in this market right now, the team is doing a good job finding projects they can to fill the facilities and delivering those projects. We'll have a little bit faster turn of projects in the two remaining businesses. That's why we moved to a fourth quarter book-to-bill type ratio. That was above one to one, so that's very positive. So they're seeing some nice momentum, but I wouldn't model mid-20s yet. We're probably a ways from being able to commit to something like that.
Unidentified Participant
Thank you so much.
James Perry - Chief Financial Officer, Executive Vice President
Thanks, Ethan.
Operator
Thank you.
And our next question comes from the line of Tim Wouts with Baird. Please receive the question.
Timothy Wojs - Analyst
Hey guys, good morning. Nice job. Good morning.
James Perry - Chief Financial Officer, Executive Vice President
Thanks.
Timothy Wojs - Analyst
Maybe just the first question. I hopped on late, unfortunately, so I'm sorry if this is a repeat, but is there any, kind of color you can give us on just some of the top-line?
If there's been any top-line contribution from bringing Mars and Aspen into this organization and kind of cross-selling that broader portfolio or is that still kind of subdued here in the near term and still kind of an opportunity on a go-forward basis, just trying to understand if you're already seeing some benefits from that on the top-line?
James Perry - Chief Financial Officer, Executive Vice President
Yeah, I would say yes and yes, Tim. I think we've certainly seen some contribution. This is now our second full season with Aspen. There wasn't a lot of that conversion last year, but the team's doing a good job cross-selling to our existing customers now that we're in kind of Season 2 of owning the Aspen business. March, we got converted over to the ERP in January, as to better serve our existing customers. I think we're seeing a little bit of that. Jeff's team has done a great job with that. But we would certainly tell you that there's opportunity for them to continue to grow. As you all know, you try to convert what. Can year one and year two, but you see conversions year three, four and five. We've got so many product categories. It takes a while for some of our customers, the turnover inventory they may have of a competitor's product. So we're getting some nice wins.
Our growth includes wins of new business, obviously, having that acquisition growth and organic growth both. So we're going to continue to see that as a tailwind, I think, going forward. But yes, you've got some contribution, but more to come.
Timothy Wojs - Analyst
Okay, great. And then when we think about just kind of the timing of input cost inflation, is kind of Q1 kind of representative of kind of the price cost cadence you'd expect this year? Or do you see some kind of higher inflation kind of creeping up through the rest of the year, at least the rest of the calendar year?
James Perry - Chief Financial Officer, Executive Vice President
Yeah, good question, Tim. It's bounced around, obviously, we clearly know that our ocean freight was.
Up quite a bit, came down quite a bit, up quite a bit since the issues in the Middle East, of course. That's made shipping rates quite a bit elevated. You've seen a little relief there the last couple of weeks, so that's encouraging, but we'll wait and see if that's a trend.
Domestic, our team has done a great job within Contractor Solutions with the trucking business, bringing the logistics side of that in-house, not owning the assets, but managing the shipping lanes and so forth. They found some nice savings, but that's been eaten up by higher diesel costs. So that's.
And as it takes a little while for that to flow through the system just given how things flow through the cost of goods sold.
Obviously, trucking is a little quicker than things like inflation of steel, aluminum, plastic costs have obviously gone up here, but those started to spike as you said back in the spring, so you're seeing that coming through now already. Our contractor solutions team raised prices.
Ranging from about 3% to 5% depending on the product back at the beginning of July. So you didn't have the price impact of that in the June quarter. We had our normal price increase back in January, so you had that tailwind, but we really just put the price increase in place in July to cover some of those other costs that were elevated. We often say we don't raise prices the minute that we see costs go up. We're patient to watch what it is, but we don't wait till the last minute either. We make sure that it's a disciplined approach. We give our customers plenty of notice.
We make sure that we get ahead of it running through cost of goods sold where we can and the team has done a great disciplined job of that of balancing what we need to pass through from an inflationary standpoint. And in terms of what we're going to see going forward, we can't predict what some of those costs are, but we have a good sense at least what's in cost of goods sold and most of it has been relatively steady now the last few weeks and couple of months that we kind of see what's in the inventory.

Okay, great. And then this is kind of a nuanced question, but I think it's a little bit important. If I remember, I think Aspen had a really good quarter last year in kind of the September quarter.
That was kind of inorganic growth, and now it's going to get folded into organic growth. So is that -- should we be mindful of that? Is that going to potentially be an organic kind of growth headwind in the second quarter, just kind of given those?
I guess kind of accounting dynamics.
James Perry - Chief Financial Officer, Executive Vice President
Yeah, it could be, Tim. I think it's a great point. You've got Mars as well now from the overall base, so you have a bigger base, but that's not going to be organic until November. Aspen had a great year last year, so the comps are a little bit tough. The selling season came a little bit earlier last year because of the refrigeration change and the canister issues and some of those things. So they had a tough June comp as well. So the June and September quarters for Aspen were really good last year. Part of that was price-based.
Just because the cost of that refrigerant had gone up, and that's kind of come back to normal for the most part now that the industry is over that hump. So yes, you've got a little bit of a headwind there. I think that's good, but I think we still feel good. As Joe said, we still feel good about organic growth across all segments for the year. But yes, it's good for you to remember that, and we'll remind people of that. It's a little early in the quarter to give specific feedback there. But yes, Aspen had a really good year last year, but pleased with how they're performing this year as well.
Timothy Wojs - Analyst
Okay, great. Well, nice job. I'll hop back in queue. Thanks.

Thank you.
And our next question comes from the line of Sam Reed with Wells Fargo. Please proceed with your question.
Sam Reid - Analyst
Hi, this is Eric. I'm for Sam. Let me get my congrats on a good quarter.
I want to ask about SRS, you had really strong organic growth, highest in looks like a few years and really strong acceleration. Just curious if there's anything sort of outside impact in Q1 that is sustainable going forward or if there's any pull forward into Q1 from the later quarters?
James Perry - Chief Financial Officer, Executive Vice President
I would say, Eric, this is James. Thanks for being on. Nothing unusual. Team is doing a great job. I mean, they're really finding the demand out there, really praise the team out there and doing a good job. As I mentioned earlier, when energy prices are elevated, you get a bit of a tailwind there because there's more of that going on. And there's a segment of our business that's indexed to that they get the favorable tailwind from that perspective. We talk about energy being a bit of a natural hedge when inflation calls some of our input costs to go up, we push that. Creates a tailwind in demand because people are producing more energy and so forth globally, so that's a good thing.
Things were, as you said, a little softer last year, so the comp helped a little bit, but overall, I wouldn't say there's anything terrible unusual, there weren't any one-offs, there wasn't a big someone earlier asked about pre-sales, it wasn't that.
We had a price increase May 1, June 1 and July 1, and we didn't really see.
Exceptional buys ahead of those price increases. So really just good job finding orders and great job executing getting things out the door.
Sam Reid - Analyst
That's great. And just on SG&A, it's very well managed and you called out lower operating expenses. Just curious where you're finding the costing opportunities and sort of how sustainable is the SG&A margin at this level or sort of what do you think you can get additional opportunities?
James Perry - Chief Financial Officer, Executive Vice President
One thing I would say, and I'll let Joe add if he wants to, we've got a bit of a commitment internally that as we grow, we don't need to add as much SG&A. We're starting to really see some economies of scale with the $1 billion we invested in acquisitions last year, and we don't need to add a whole lot of folks to manage that, Joe.
Joseph Armes - Chairman of the Board, President, Chief Executive Officer
No, it's a really important part of the algorithm for value creation here is that -- and we talk a lot about the.
Volume leverage, but that has a cost component. And we have to be mindful of costs creeping up.
And we are very vigilant in trying to make sure that these shareholders get every bit of benefit out of these acquisitions that they should get. So it's a great question. Glad you asked because I think the cost containment has been a little bit of an under.
Appreciated part of the story here. But yeah, top-line growth provides the opportunity for operating leverage, and so the cost containment is a key part of really realizing that.
Thanks, Eric.

Thank you.
And our next question comes from the line of Susan McClary with Goldman Sachs. Please proceed with the question.
Susan Maklari - Analyst
Thank you. Good morning, everyone.
My first question is on the supply chain. Can you give us an update on the efforts there to move some of your production to Vietnam? And then I guess with that, just talk generally to the impact of tariffs and anything that's changed from that perspective?
James Perry - Chief Financial Officer, Executive Vice President
Sure. So this is James. Yes, we continue to move things as we can into Vietnam and Thailand is another good home for us right now. We've talked about as we make acquisitions, they tend to have a little more in China. So we kind of take a step backwards and then a step forward. So we're doing a great job. Overall, we continue to be around those same numbers. Vietnam is kind of in the low 30s as a percentage cost of good sales. We look at this fiscal year kind of going forward where we're targeting within Contractor Solutions. The U.S. Is about 45% to 50% or so. Thailand's upper single-digits and then you got a little strewn around here and there, China's around 10%. So we keep hovering around that 10%. The goal is to continue to take that down, but again, acquisitions tend to have some of that and we've done a good job. We've talked about, we've even got some folks that have set up their own shops within Vietnam from other countries because it's a favorable place to do business and we've helped them do that. So it's not always just moving into our own facility there in Vietnam. So I think the team's done a good job. The numbers have. Haven't moved dramatically.
And part of that is, again, just getting some of the acquisition-related supply chain out of China, but the team has done a great job and we're very comfortable where we are. In terms of tariffs, things have been relatively stable. The HVAC parts got a little bit of relief and so that helped us. It helped us keep down that most recent price increase we put in early July, having that benefit knowing that those tariffs were going to be helped a little bit. The most recent tariff activity last Friday really. Just replaced what was there before. The 10% goes to either 10% or 12%, depending on where you are.
Some of the things are not impacted by that at all because they're under a different tariff structure. So some of our parts coming out of Vietnam and other places are not impacted by that. So there was no change as a result of that. So on the whole, the last few months have been relatively stable from a tariff perspective.
Susan Maklari - Analyst
Okay. All right. That's very helpful color. And then maybe turning to the M&A pipeline, can you just talk about what you're seeing there, your appetite for some smaller deals, especially as you've hit some of your key hurdles with Aspen and Mars, and then how we should also just be thinking about other priorities for capital allocation?
Joseph Armes - Chairman of the Board, President, Chief Executive Officer
Sure. No, it's a great question, Sue, and this is Joe.
We continue to see a number of opportunities. I feel like we're seeing all of the opportunities that are reasonable for us to see.
And as I think we've talked about 10 years ago, that wasn't the case. We were small. We didn't have a track record of success in doing acquisitions and integrating them successfully.
And now we do. And so we see most every opportunity that I think we should see.
Which is really good. Our rigor and analysis and our discipline and investment continues to be a real focal point for us. But yes, there is a nice pipeline, robust pipeline of smaller deals in particular right now that we've been analyzing and evaluating. And as you noted, we needed a little bit of digestion period here with these larger acquisitions. I feel like we're largely through that. The success of the team and continued kind of.
Performance on integrating well gives us even higher level of confidence in our ability to continue to do that going forward. So as we think about capital allocation broadly, the rubric remains the same. I mean, we are going to evaluate everything on risk-adjusted returns. And I will tell you for the past quarter, the most attractive risk-adjusted returns was to invest in our own stock. And so that's what you saw. It's what we've done. We've paid down some debt as well. There's a nice return on that. So all options remain open to us and we'll continue to invest in the highest risk adjusted return opportunities.
Susan Maklari - Analyst
Okay, that's great colors.
Thank you and good luck with the quarter.

And our next question comes from the line of Andy Kaplowitz with Citigroup. Please proceed with your questions.
Andrew Kaplowitz - Analyst
Good morning, everyone.
Hi, Andy.
George James, just back to Mars for a second. I think you've talked previously that there's a trade-off between for your core contractor solutions business and Mars that you're working on in terms of who's got the best products and which ones you're going to focus on. So has that continued to happen? And I didn't catch Mars growth. Did you disclose that?
Was it still negative. Quarter or did it turn?
James Perry - Chief Financial Officer, Executive Vice President
Yeah, let me first address the first part. The team's done a great job with the product rationalization work that they've been going through.
They've done that for the most part. They've picked the best product from kind of each category. As we've said, at times, we pick a product that's got maybe a lower cost base and push it through our distribution network. Our customers have received that very well. So we're really pleased with that. We did not give specific MARS.
Performance. Now that it's pretty fully integrated within Contractor Solutions, it will become organic in a few months, but we didn't break that or Aspen out anymore, that's kind of behind us. We did talk about the $13 million of synergies that we're seeing now up from the original 10. We've talked about we've already hit the 30% EBITDA margin target two quarters in a row ahead of schedule, so we're pleased with that. So yes, we're not breaking out the specifics anymore, now it's just really so well integrated as part of the segment.
Andrew Kaplowitz - Analyst
Helpful, I mean, I think last quarter, you talked about not taking price increases in Contractor Solutions and then of course you just told us that you took them in July, but you still grew EBITDA margin in Contractor Solutions in Q1 even without them.
We talked about fluctuating freight and commodity costs, so I know you don't want to get specific forward guidance, but can you continue to grow Contractor Solutions, EBITDA margin over the next few quarters, given sort of the puts and takes with the price and the inflation that we've talked about?
James Perry - Chief Financial Officer, Executive Vice President
Yes, we had the price in July, which really covered what we need to do for inflation. So that's usually not a margin enhancement. We kind of work over time to get that back. When we do mid-year price increases, that's really kind of neutral from a dollar perspective. And it, in fact, can be a tiny bit of a headwind to margin for a little while, and we work to get that back over time with our annual price increase as appropriate or finding ways to cut costs. The team is always looking to do that as well.
The 34% margin, very pleased with that. Obviously, Mars getting well above the 30% number now. We're pleased with that. That's a contributor. That wasn't in the portfolio a year ago. Aspen was there a year ago. And Aspen is a bit diluted with that just given the nature of the business. So I don't think we would commit to margin expansion necessarily. As the summer month is going to be the best margin. So quarter-to-quarter, things are going to fluctuate.
Kind of the quarter we just finished in the one we're in or the high water margin and then. Have your lower margin kind of dip in December and then start recovering in March. So we've always said being in the low 30s is premier industry-wide margins. We've grown that overtime, but we've always said that if we can grow the top-line and maintain these margins, we'll be thrilled. So very pleased with the quarter that the team put together, the goal is to continue to produce good margins. But yes, to your point, not giving guidance, I don't think we'll commit to where these margins are going forward or the ability to grow necessarily, but we're very pleased with the performance there.
