I encourage all of you to review the risk factors listed in these documents. Now, I will turn the call over to Gartner's Chief Executive Officer, Jean Hall.
Good morning, and thanks for joining us. For the third quarter of 2019, we continued to deliver strong performances across our business. Total revenues were up 11%, fueled by dumbest growth in each of our business segments. Research, conferences and consulting. We continue to make a significant global impact through these segments.
We helped more than 15,000 enterprise clients more than 100 countries around the world with their mission critical priorities, while providing great jobs to more than 16,000 associates globally. Research, our largest and most profitable segments, is the core of our value proposition. Our research business was up 10% over the span last year. The Gartner Formula for sustained double digit growth continues to drive success in our research business. As we previously highlighted, the Gartner Formula consists of indispensable insights, exceptional talent, sales excellence, and enabling infrastructure.
For each of these elements, we drive relentless, globally consistent execution of best practices and consistent improvement and innovation. Global Technology Sales or GTS serves leaders and their teams within IT. This group represents more than 80% of our total research contract value. GTS contract value growth was 13% year over year. We delivered double digit growth in every region across every size company and in virtually every industry.
Global Business Sales or GBS serves leaders and our teams beyond IT, and represents about 20 percent of our total research contract value. This includes supply chain and marketing, which we address for several years, as well as other major GBS continued on a path toward double digit growth with total GBS contract value accelerating to 3%. Our GXL product line continued to gain momentum with contract value increasing $26,000,000 sequentially. GXL products provide greater value to clients because they're tailored to the client's individual needs. This in turn results in higher prices for user and stronger retention.
Beyond better pricing retention, GXL products provide exponentially more growth opportunities because we can sell these high value products throughout our clients' organizations. For Q3, GXL contract value grew 65% year over year and new business was up 39%. We expect continued acceleration and retention improvement is the same as it was in Q3 contract value growth will be 9.6%. Our Conferences segment also delivered a terrific performance in Q2 with double digit revenue growth of 19%. Gartner Conferences combine the outstanding value of research with the immersive experience of live interactions, making every conference we produce the most important gathering for the executives we serve.
I recently attended our IT Symposium Conference in Orlando, Florida. This conference is the most important gathering of CIOs and senior IT executives in North America. We hosted around 8000 attendees on-site and about 3000 of these were Chief Information Officers. This is near our all time highs. At our conferences, you can see firsthand the power of Gartner in helping clients achieve their mission critical priorities.
Clients received incredible insights from our analysts. They networked with leading peers and experienced leading edge technology for the most important providers in the world. Our executive attendees were inspired and empowered to succeed as a result of the insights we delivered at this important event. Our associates were equally inspired and excited about the incredible value we deliver to our clients. Our Consulting segment also achieved double digit growth in Q2, with revenues up 20%.
Gartner Consulting is an extension of Gartner Research and provides clients a deeper level of involvement through extended project based work to help them execute their most strategic initiatives. Our growth in the quarter was a combination of our labor based business and strengthen our contract optimization business. So we delivered another strong We continue to have a vast market opportunity. We made investments over the past 2 years that position us well to capture that market opportunity. We're preparing our 2020 business plan and expect to continue attractive double digit growth.
We've planned to maintain expense growth in line with revenue growth by leveraging investments we've made over the past 3 years. Specifically, we expect total expense growth to be in line with total revenue growth. We've had a strong history of continuous improvement and continuous innovation. We're shifting the emphasis of our innovations and improvements to be on more tightly managing expenses. Sales is one of our largest expense categories.
And sales will be implementing significant innovations that we expect will improve sales expenses relative to contract value. Here are three examples: Territory design is an important factor in determining a salesperson's productivity, especially in a growth company. We've developed a highly sophisticated territory planning capability over the past few years. For 2020, we're making a major advance by making the is how quickly new sales hires get into the territory and make their first sale. Over the past few years, we developed a very strong recruiting capability.
For 2020, we're implementing changes to the recruiting process, which will allow us to put sales people in territory just in time, analogous to just in time manufacturing. A third factor impacting sales expenses training. Over the past few years, we developed sales training that is broadly recognized as being outstanding. For our next evolution, we're reducing the amount of upfront training and shifting this training to be just in time as the salesperson needs it. This will enable us to be even more effective, while getting sales people into territory even faster.
Beyond sales, we expect to get leverage from the G And A investments we've made over the past few years. We've already begun making these changes to ensure we get the full impact in our 2020 plan. Summarizing, we're shifting to getting returns from the investments we've made over the past 3 years while maintaining the long term growth that captures our enormous market opportunity. Looking ahead, we are well positioned for sustained long term growth. We expect continued sustained long term growth in GTS.
We expect continued acceleration in GBS and conferences and consulting are on a strong path. Looking ahead to 2020, with the great strategic positioning of GTS and GBS, together with leveraging the investments we've made, we expect double digit top line growth and EBITDA growing approximately in line with revenues. With that, I'll hand the call over to Craig.
Thank you, Jean, and good morning, everyone. Global Technology Sales, the largest part of our business, continues to deliver strong double digit growth. Global business sales continue to accelerate after inflecting the growth last quarter. Our strategy to deliver products and services with a compelling value proposition across all enterprise functions is working. Conferences and consulting are having outstanding 3rd quarter revenue was $1,000,000,000, up 10% as reported and 11% on an FX neutral basis.
Top line growth was impacted by about 100 basis points in the quarter from the product retirements we previously discussed. In addition, contribution margin was 64 percent, down 10 basis points from the prior year. EBITDA was $140,000,000, ahead of expectations, although down 6% year over year and 5% FX neutral. Adjusted EPS was $0.70, and free cash flow in the quarter was $190,000,000. Our research business had a strong quarter.
Research revenue grew 9% year over year in third quarter 10% on an FX neutral basis. 3rd quarter contribution margin was 69 percent. Total contract value was $3,300,000,000 at September 30. Growth of 11% versus the prior year. I'll now review the details of our performance In the third quarter, GTS contract value increased 13% versus the prior year.
GTS had contract value of $2,600,000,000 on September 30, representing just over 80% of our total contract value. Client retention for GTS remained strong at 82%. While retention for GTS was 105% for the quarter, down 16 basis points year over year. Our wallet retention rates show that our clients spend more with us each and every year because of the value we provide to them. GTS new business grew 12% versus the third quarter of last year, a strong rebound from 2nd quarter.
New business is coming from a mix of new enterprises and growth in existing enterprises through sales of additional services and upgrades. We ended the 3rd quarter with 12,728 GTS Enterprises, up 2% compared to Q3 2018. We've added over 1600 new enterprises so far in 2019. The majority of client losses are with our smaller, lower spending clients which you can see in the client retention rates. Moving forward, The average contract value for enterprise continues to grow.
It now stands at $208,000 per enterprise in GTS. Up 11% year over year. Growth in CV per enterprise reflects both price increases as well as up sell and increased numbers of subscriptions. At the end of the third quarter, we had 3355 quota bearing associates in GTS, or growth of 14% year over year. We have made investments in the GPS sales force and have seen CV accelerate from 2017.
Following the additions we made late last year and early this year, we are recalibrating our expense growth to ensure we align it with GTS CV growth. These changes are consistent with our continuing We expect GTS headcount growth to end 2019 at approximately 10% with the hiring we've done Salesforce has the capacity to grow GTS contract value between 12% 16% per year, consistent with our medium term guidance. For GTS, the year over year net contract value increase or NCVI divided by the beginning period quota bearing headcount was $104,000 per salesperson, down 4% versus the third quarter of last year. The higher headcount growth late last year and into this year brought down the average tenure as new sales people take time to get the full productivity. One of the benefits of moderating the headcount growth exiting this year and moving into 2020 is that average tenure will increase, which should improve productivity.
Turning to Global Business Sales. GBS contract value was $620,000,000 at the end of the 3rd quarter, or about 20% of our total contract value. The momentum we saw last quarter continued with GBS CV increasing 3% year over year. The acceleration in GBS contract value was driven by strength in GXL. Total GBS new business was up 26% and retention improved as well.
GXL products are an important part of our strategy and continue to gain share. Looking at total contract value from the GXL products, we drove an FX neutral increase of 65% year over year. $154,000,000 to $254,000,000 We've updated the GXL data we provided the last few quarters on Page 11 of the earnings supplement to highlight the trend in GXL new business and contract value. We sold $35,000,000 of GXL new business in Q3, up 39% versus the prior year quarter. We continue to make More than half of the GXL new business in the quarter came from newly launched products.
GXL CV now makes up 41% of our total GBS contract value. Up fifteen percentage points from Q3 of last year. We are driving increased client engagement through expanded service teams and growing adoption of individualized content and service. For the standalone the quarter, we drove attrition rates down for GBS. For contracts that were up for renewal in the 3rd quarter, attrition improved by about 500 basis points over the prior year quarter.
Again, this is a result of the increased engagement we've discussed, a richer mix of GXL renewals and all of our other retention programs having an impact. Our path to continued acceleration and double digit growth for GBS the past double digit growth is based on new business growth and attrition improvements consistent with Q3.
At the
end of the third quarter, we had 910 quota bearing associates in GBS or growth of 19%. Headcount was down sequentially as we are recalibrating our cost base. We expect GBS headcount growth to moderate by the end of the year, as we shift to reap 16% year over year in Q3 to $66,000,000. FX neutral growth was 19%. 3rd quarter contribution margin was 41%, down 2.39 basis points from an especially strong third quarter of 2018.
The largest impact on the year over year Q3 contribution margin comparison was the movement of our Europe supply chain conference into Q2 On a year to We had 18 destination conferences in the third quarter. On a same conference, FX neutral basis, revenues were up 20% a 9% increase in attendees and a 100 basis point improvement in same conference contribution margin. Turning to consulting. 3rd quarter consulting revenues increased by 18% year over year to $93,000,000. FX neutral growth was 20%.
Consulting contribution margin was 28% in the 3rd quarter. Labor based revenues were $78,000,000, up 11% versus Q3 of last year or 13% on an FX neutral basis. Labor based billable headcount of 809 was up 11%. Utilization was 57% as the third quarter is our seasonally lowest utilization quarter and also when our annual MBA hires join the company. Backlog at September 30th was $109,000,000, up 3% year over year on an FX neutral basis.
Our backlog provides us with about Contract optimization revenues were up 74% versus the prior year quarter. We have detailed in the past, this part of the consulting segment is highly variable. The compares get significantly more challenging in the fourth quarter. SG and A increased 15% year over year in third quarter and 17% on an FX neutral basis. We will continue to grow sales capacity and the enabling infrastructure to support our strategy of delivering sustained double digit growth over the long term.
We have started the process to recalibrate the sales and infrastructure investments to align cost growth with revenue growth. EBITDA for the third quarter was $140,000,000, down 6% year over year on a reported basis and 5% on an FX neutral basis. In the third quarter of this year, EBITDA was adversely affected by about 4 percentage points or a $5,000,000 impact due to the product retirements we've discussed. Taking that into consideration, underlying FX neutral EBITDA was down about 2% in the quarter. Depreciation was up about $3,000,000 from last year as additional office space went into service.
Amortization was flat sequentially. Integration expenses were down year over year as we have moved past the biggest part of the integration work. During the quarter, we recognized an unrealized the gain is the gain is in other income. This was a heritage CEB minority investment in a small company, which was acquired. Net interest expense, excluding deferred financing costs in the quarter was $22,000,000, down from $25,000,000 in the third quarter of 2018.
The lower net interest expense resulted from lower average debt balances of roughly The Q3 adjusted tax rate, which we used for the calculation of adjusted net income, was 22.8 percent for the quarter. Lower than expected as 24.2% in the quarter. Adjusted EPS in Q3 was $0.70, above our expectations due to operating upside and a lower tax rate. In Q3, operating cash flow was $220,000,000 compared to $249,000,000 last year. The decrease in operating cash flow was primarily driven by lower EBITDA.
Q3 2019 CapEx was $36,000,000, Q3 acquisition and integration payments and other nonrecurring items was approximately $7,000,000. This yields Q3 free cash flow of $190,000,000, which is down 17% versus the prior year quarter. Normalizing 2018 for divestitures and working capital percent of adjusted net income, excluding divested operations and working capital timing. The lower conversion is due to timing and we expect to finish the year with a conversion rate about $2,200,000,000. Our debt is effectively 100 our gross leverage ratio is now about 3.3 times EBITDA.
We repurchased $95,000,000 of stock in the quarter at an average price of about $134 per share. We will continue to be price sensitive and opportunistic as we return capital to shareholders. We had $777,000,000 remaining on our repurchase authorization. Our capital allocation strategy remains the same. We deploy our free cash flow and balance sheet flexibility by returning capital to our shareholders through our buyback programs and through strategic value enhancing M and A.
Earlier this month, we acquired Topo, a provider of insight and advice for sales leaders. The overall purchase price was $33,000,000 with a portion of the consideration deferred for a couple of years. Revenue, adjusted EBITDA, free cash flow and adjusted EPS guidance all remain unchanged from last quarter. The top line growth outlook on an FX neutral basis remains strong and we are committed to the same second half targets we provided in July. As you're thinking about the 4th quarter in the context of the 3rd quarter results, there are two points to keep in mind.
First, consulting outperformed our the fourth quarter. And second, as we began the process to realign our expense growth with our revenue, we shifted some costs out of Q3 and into Q4. Our guidance reflects FX rates as of September 30. FX is causing a roughly 2 point negative impact to projected 2019 full year growth rates across revenue, EBITDA, adjusted EPS and free cash flows. The highlights of our full year guidance are as follows: we expect FX neutral revenue growth of 10% to 11%.
We expect adjusted EBITDA in FX
neutral terms
for 2019. That implies a mid-fifty percent rate for the fourth quarter. Our tax planning related to our intellectual property is ongoing and we anticipate incremental tax costs in the fourth quarter. Please note that if you are adding back from GAAP net income, The rate for the tax effect on the add backs is also about 25.5%. For 2019, we expect free cash flow $400,000,000 to $430,000,000.
That is a projected FX neutral change of down 2% to up 5% versus our normalized 2018 free cash flow. All the details of our full year guidance are included on our Investor Relations site. In summary, GTS contract value growth continues to be strong and sales of our new GXL products and GBS continue to rise. Our conferences and consulting businesses both had great quarters. We expect to finish the year with free cash flow conversion from net income in the high 120%.
As we prepare for 2020, we are actively recalibrating our investments to ensure cost growth is in line with revenue growth. And we continue to apply the Gartner formula across the combined business to drive sustained long term double digit growth to revenues, EBITDA and free cash flow. With that, I'll turn the call back over to the operator and we'll be happy to take your questions.
Our first question comes from the line of Jeff Meuler with Baird. Your line is now open.
Yes, thank you. To start, can you just give some more color on the improved GTS new business sold trend. And I guess what I'm wondering is last quarter, you talked about at an abnormal amount of management or operational change and that had some impact. I'm just curious, does it tie back to those regions or just anything you can say about the improved GTS new business, Siltron.
Hey, good morning, Jeff. Thanks for the question. I think, our new business performance Obviously, we want to drive consistent double digit improvements in our new business on a year over year basis. We got back on track for that trend in the third quarter with strong new business growth. I think that, the challenges we detailed last quarter, we are working our way through them.
It takes time to work through them. So I would definitely not attribute the rebound to those things all bounce back. But I just attribute it to 1, we have a huge market opportunity, which we continue to go after. 2, we've continued to grow our sales force to go after that opportunity. And 3, we have an expectation that will drive double digit growth in our new business, to basically support our sustained double digit growth within GTS.
Okay. And then on the way that you're managing expenses and margin, I know it's being well received from your shareholder base, but I guess just want to make sure that the way you're managing it doesn't ultimately impact growth. And I hear you on the GBS sales headcount that you've kind of already made the investment and it's time to harvest that. But the other things that you're citing, they sound to me like kind of the continual improvements that Gartner is always making. So am I wrong about that?
Is there some reason why we should think that those productivity impacts will be bigger from this round of initiatives or are there other areas other than kind of harvesting GBS sales headcount where you're actually, reducing spend or not making investments that you otherwise would have made?
Hey, Jeff, it's Jean. I put in 2 categories. 1 is or 3 categories, I'm sorry, 3 categories. 1 is sort of in GBS where again, as you correctly articulated, we made some major investments since we acquired, since we acquired CEB, We're seeing those returns on those investments. And now we're very focused on making sure we get those returns to the investments.
We're kind of we've got the Salesforce trained. We've got the products introduced. And so now we want to make sure we focus on getting returns from that. And so we see a big upside there. Secondly, in GTS, similarly, we made In GTS, similarly, we made some investments over the last during that same period of time.
And we invested a little higher rate than we had invested even before this EV acquisition. And we have a similar situation, just not as pronounced as it was on the GBS side. And some of the changes involves some innovations like I took you through 3 of them that we think are, material innovations that will affect in particular, the expense relative to contract value, which is really important in sales. And the last thing I also mentioned, which is We do think that there's some leverage, we can get out of our G and A, that we haven't gotten over the last couple of years. And I'll give you an example, which is As we grew, we had some major real estate projects.
Those projects are now a point where we can start getting the benefits from those. And so we have less of a drag in G and A from those. Is part of the reason we can expect, as I said, G and A to grow slower than our overall revenues going forward.
Our next question comes from the line of Manav Patnaik with Barclays. Your line is now open.
Thank you. Good morning. I was wondering if you could just talk a little bit more around the client count reduction. It's been three quarters now. I know you said most of it was on the small business side, but that's usually the case.
So I was just wondering, is there anything incremental and your confidence on growing that again, are you going to shift strategy to more of the larger accounts or just if there's any change there at all?
Good morning, Manav, and thanks for the question. I think on the enterprise count thing or the enterprise count trend, I should say there are a few things going on there. One is, as we've talked about in the past, any M and A obviously will impact that count. And we have been in a period where there's been more M and A than normal. And that has a modest impact on the count.
The second piece, which we talked about last quarter, was we're continually refreshing and updating our data sources And that does and has over the last 3 or 4 quarters, impacted the enterprise count a little bit. To the negative as we've cleaned up data and consolidated certain enterprises. Again, another modest impact The third thing I'd say is, which I alluded to in the prepared remarks, we're continuing to add new enterprises at a very strong clip in GTS. As I mentioned through the first three quarters, we've added over 1600 gross new enterprises. You will note a modest uptick or downtick, I should say, in our client retention rate.
And essentially you're not seeing the the increases you've historically seen in our enterprise count because of the cleanup and because of the small downtick in the client retention rate. Going forward, I don't think there's any change in the strategy. It's not about going after larger companies. The note I'd make around really small, companies and small tech companies in particular is we have a different strategy around how we're attacking them. The bulk of our market is really not them.
And so we want to make sure that we handle that bit of the business in a more efficient, more effective and more profitable manner, but the market opportunity remains really, really, really vast. And we'll continue to go after that opportunity, by adding new sales people and by growing the enterprise count over the long term.
Okay, got it. And Jean, just to follow-up on your last comment there around seeing the returns on a lot of your investments and making sure you see more I guess how will we see it? Like shouldn't we also see some of that with some signs of improved margins given the heavy mid or is that maybe 2 years out, which is why you guided flat margins for next year?
Yes. Hey, Manav, I'll jump in you mentioned margin. So Jean looked over to me. So I think the way to think about it is, I think you're right. So two things.
One is we're not providing 2020 guidance yet. We're working our 2020 operating plan as we speak. And we'll give you and all of our investors the details of that plan in early February. 2, I do think there is time that takes to actually see those benefits flow through, especially given the ratable nature of the bulk of our revenues. And so with Jean, with Jean stated in which I affirmed is, we believe for 2020, revenues and expenses and EBITDA will grow roughly in line with one another.
And in my mind, that's the first step towards seeing the real benefits of all the investments we put in place.
All
right. Got it. Thank you guys.
Our next question comes from the line of Gary Bisbee with Bank of America. Your line is now open.
Hey guys, good morning. Jean, I guess the first question for you on the sales changes that you mentioned you just give us a little more color? I've always thought your sales training was a key part of your long term success. So reducing that upfront more, I guess, you said, just in time as you go, what does that really mean? And is there any productivity risk around that and similar concept on the recruiting process changes or even the new way you're managing territories.
What's the risk to those strategies? Thank you.
Let me just, I mean, there's clearly risk anything you do, but we think these are actually have a lot of upside to it. And let me just take, for example, the training piece. So the way we have traditionally trained is we'll bring a new person on and depending what role they're in and what geography they're in, the training is 6 to 8 weeks long. It's really good training. We have a we have it really gives them a lot of tools.
What we found is after being in training for a couple of weeks, kind of retention of what they've learned isn't as high as you'd like. Training to again, it'll vary, they call it approximately 2 weeks. And then delivering the others, other training as they're in throughout their 1st year, but when they need it. So for example, you might have a training session on how to handle client objections for particular product. And you get that train upfront.
Well, it's much more applicable. If they're about to talk to a client about that particular product, the are strong on how to handle objections the day before as opposed to 3 months beforehand where they the retention, that they're they remember about what they were told is a lot lower. And so the way to think about it is they're going to get the same amount of training, but this is actually a much more effective way to do it. Because we give them the basis what they need upfront. And then each week they think about each week they would get a booster on the specific things they need to address the challenges they have with their client base that particular week.
And so the total training, we're not thinking of is less. It's just a smarter way to do it. Where they get it, where they can really use it. Any studies that you read and our experience is the same, which is if you get training the day if a salesperson gets trained the day before they have to actually use it, they pay a lot higher attention than if it's the 5th week, 6 weeks of training for something they're going to use structure because then we have people into territory sooner. And so instead of going to church where after 6 or 8 weeks, they'd go into territory after 2 weeks.
And so they actually start learning their client and get to that first sale faster, which gives them a lot of confidence.
Great. That's helpful. And then, Craig, just one for you. When you talked about free cash flow, I think I heard you say ex the divestiture is fine, but did you also say when you're talking about conversion ex working capital movements and if so, 2 parter, are you changing how you talk about cash flow conversion? Number 1, number 2, is there anything about the working capital characteristic, particularly now that you've got CV growing at GBS that we should think is different than what it's been in the past?
Good morning, Gary. Good question. So the working capital timing adjustment that we've discussed relates to the catch up where we got behind at the end of 2017, which we talked about, which really impacted 20 17 free cash flow. At the time, we said it was about a $40,000,000 impact of free cash flows because we had challenges in the integration. We getting the invoices out about $40,000,000 of 2017 free cash flow slipped into 2018.
And so when we talk about the adjustment, the adjustment for working capital timing, that's putting that $40,000,000 back 2017 when we do the year over year comparison to get a better view on what the true organic growth rate is in free cash flow. And then on the second part of your question, no change to the working capital characteristics of the company. We remain really focused on making sure that we leverage and get the benefits out of the negative working capital characteristics of our research businesses We're very, very, very focused on that as we've discussed in the past. And as you alluded to, as GBS contract value accelerates. That clearly is a benefit on those negative working capital components because as that business is growing faster.
We get to take more advantage of it. And then the third thing I'd say is we remain very focused on improving the efficiency of our working capital back to see us continue to get the benefits, perhaps even get more benefits out of the fundamentals of our our working capital model as we grow both GTS CV and GBS CV.
Thank you.
Thank you. Our next question comes from the line of Toni Kaplan with Morgan Stanley. Your line is now open.
Craig, you mentioned the 2 main reasons for keeping the guidance the same, the consulting and the expenses shifting into Q4. Would you say there is some more conservatism in the guidance than last quarter? And are there any incremental factors that you're seeing, that are, are maybe a little bit less good and that's the reason you're keeping it the same.
Yes. Hey, good morning, Tony. Thanks. Thanks for the question. I think, the way to think about the guidance is when we came out of Q2, and with our adjustments there, we were very focused on delivering what we committed to over the second half of twenty nineteen.
And as we roll through Q3, I'd say, again, the 3, the 2 things I mentioned on the call, most notably the timing around consulting and and deferral certain expenses, into from Q3 into Q4. Certainly were the largest impacts. You might argue we were a little conservative in the Q3 number when we came out with it, but I would not imply huge overarching conservatism over our second half target, which we remain committed to.
Okay, great. And then I wanted to ask about conferences. I think I probably hadn't appreciated the link between conferences and research sales as much as I should have. And so can you just talk about how the GBS conferences have been going. And I guess if there's any way to quantify, how much benefit you normally get from a conference translating into research sales later on and, anything to in terms of improvement with Avanta, that'd be great.
Thank you.
So our, Tony, our conference is our great business and it's a great way to leverage our research. When we do research, on a particular topic. Obviously, that's very relevant to the people that are research clients. It's also very relevant to people that are not yet research clients. And so we've introduced, as you pointed out, the conferences of GBS, taken some of the ones that we had before that were smaller.
And those have all done great. They've really grown very rapidly They've been very attractive to both the existing research clients as well as people buy their own tickets separately. And we intend to continue that whole strategy.
Thank you. Our next question comes from the line of Andrew Nicholas with William Blair. Your line is now open.
Hi, good morning. Thanks for taking my questions. I want to talk about GBS a little bit. When we're thinking about your ability to get to double digit CV growth next quarter, Is that entirely a function of generating new GXL business? Or do you think there's still a little bit of room to go in terms of improving your legacy attrition?
Hey, good morning, Andrew. I think it's absolutely both. As we've discussed, throughout the year. Our focus clearly has been on GXL and GXL new business and that's been going really, really well for us as we've described. And as you can see in our disclosure information, I would note though that we have also been very focused on improving the attrition rates across the entire GBS portfolio.
And so the numbers we've given over the past couple of quarters have been inclusive of both GXL and the legacy leadership councils. And we've seen really significant and material improvements in our attrition rates and they've improved from quarter to quarter to quarter. With our best quarter so far being Q3. And that's across both GXL and legacy leadership council business. And so yeah, that is absolutely a big lever for us.
The bigger lever is clearly continued momentum in GXL new business. But every dollar we save from a nutrition perspective obviously helps to accrete the overall growth rate.
Great. Thank you. And then, within GSL, again, I know you targeted a number of different verticals there, HR sales, so so forth. I'm just curious if you could speak to where you're seeing the most traction. And then maybe on the flip side, which verticals you would like to see grow a bit faster.
Thank you.
Yes, I'll talk to the quantitative part of that question and Jean can talk strategically. I think the really nice thing that we've seen since we launched the GXL products is each of the functions that we serve we've seen really, really strong continued strong growth and accelerating growth. And one of the things we keep mentioning is more than half of the new business we've generated in each of the last three quarters more than half of it has come from the new GXL products that were launched post acquisition. So meaning, we're doing well. We continue to do well.
On the marketing and supply chain GXL offerings that we had prior to, the CEB acquisition. But we're really growing rapidly across all the functions that we now have GXL products for. And again, whether you look at HR or legal or finance, they're all doing really, really well. DXL new business in each of those enterprise functions is up significantly on a year over year basis. And we've seen really nice progress across all of the functions.
Yes, Nathan, I can add to it there. We don't have a place that we sort of say, Hey, it's underperforming relative to the expectations.
Got it. Thank you.
Thank you. Our next question comes from the line of Jeff Silber with BMO Capital Markets. Your line is now open.
Thanks so much. I wanted to go back to the margin discussion. If I go back a number of years ago before you guys bought CEB, now GBS, you were generating adjusted EBITDA margins of close to 19% or so. I know GBS was a different business. You've made a lot of investments and a lot of improvements, but think when you bought the company, you were hoping to make it a Gartner like company, which you're making significant amount of progress already.
Do you think we can get back to these adjusted EBITDA margins around 19% over time?
Good morning, Jeff. I think we are committed as we've talked about to getting returns on the investments we've made And we spent a lot of time this morning talking about in last quarter as well, talking about ensuring that we are aligning our cost structure to our revenue growth. And so I think the way to think about it is we are committed to that. We're going to go after that. And when we get through 2020, we can start talking about what 2021 2020 2 2020 3 look like.
But for now, I think we're very focused on finishing this year, making sure that the enter 2020 in the best possible condition, both from a bookings perspective and also from a cost structure perspective. And then we're going to take it from there.
Okay, fair enough. Thanks so much. Thank
you. Our next question comes from the line of Joe Foresi with Cantor Fitzgerald. Your line is now open.
Hi. I guess my first question here is just around It seems like there's a shift in strategy and that maybe the investment cycle for GXL is over at this point. Is that accurate? And if so, why this quarter versus other quarters?
So, hey, it's Jean. So there is a shift in strategy, right. And the shift in strategy, we over the last 3 years, we've been investing for the future In particular, with things like getting the GXL products in place, getting the Salesforce trained on it, getting our Salesforce capacity up, moving the all of the GTS tools and training and so forth into GBS, that all took a lot of investment. We've now made those investments and we feel like that there's leverage we can get out of those. And so there really is a big shift in strategy from putting those investments in place to now actually we have them in place and getting acceleration to take advantage of those investments.
Obviously, and so we vote a hefty investing ahead of our CV growth, particularly in GBS. Now we want to make sure that we get all the levers we can out of those investments.
Okay. And then secondly, and I guess this is for you, Craig, because you get the margin questions or Gene will at least point to you for On the margin side, if GXL improves and the revenues accelerate there as you're implying with the guidance and the contract value. Is it fair to say that margins will follow it, up? Because I mean, it's been sort of the area of dilution. Or is there any reason to think that there would be a separation there?
Thanks.
Good morning, Joe. Thank you. So again, I think the way to think about it is that as Jean just mentioned, we have invested a lot the investments are largely in people, and we continue to pay those people in that cost base is relatively fixed, but we'll continue to go up with inflation and things of that nature. I we absolutely do believe that as we accelerate our, the DXL business and the GBS business in total, That all other things equal, but it's definitely a help for overall margin profile and margin position. I would remind you that GBS only represents about 20% of our total contract value.
And probably only 15% of our total revenue. And so it does have an impact, but a modest or more muted impact than you might think just given the size of it, the real kind of margin or profit profile or incremental profitability that we generate really comes out of our GTS business, which is again, at $2,600,000,000 business. That's growing at 13% per year. And again, we remain committed to making sure that We align our cost base with our cost base growth, with our revenue growth, and that's how we're thinking about it as we plan for 2020. And as we roll again into future years, we will continue to update everyone on how we're going to manage the business going forward.
Thank you.
Thank you. Our next question comes from the line of George Tong with Goldman Sachs. Your line is now open.
Hi, thanks. Good morning. You indicated earlier that GBS CV growth will be about quarter if new business and attrition improvements in the 3rd quarter carryover to 4Q. Can you outline precisely what assumptions that involve and maybe talk about the top 2 or 3 factors that could cause the trends from 3Q not to carry over to 4Q?
Yes. Hey, good morning, George. So the top line assumptions are new business growth of 26% year over year, which is what we achieved in Q3 and about a 500 basis point improvement in the attrition rates, which also is what we achieved in Q3. And so as Jean went through the math, those are the assumptions that we've used to get to that 9 point 6% based on the amount of contract value we have expiring in the fourth quarter. As you know, Q4 is a big quarter for us in total for GBS in particular, both on the new business side, where we generate significant amount of our new business in the fourth quarter and also with our expiring CV, it tends to be the or it is the the highest weighted quarter in terms of expiring CV.
But again, if you just extend what we saw in Q3 into Q4 with a new business improvement, and the attrition improvement. If you run that math, you get to 9.6%.
Got it. That's helpful. And I want to tackle the margin a little bit differently. Last quarter, you took down the full year margins from about 17.5% to about 16 percent at the midpoint for EBITDA because you were pulling forward the open territory hires and now it sounds like you're going to recalibrate your expense growth to match the top line growth and it's going to take about a year for 2020 for that to happen, so roughly flat margins. But as you manage the margins, longer term, is there room for the margins to get back to where they were just about a quarter ago in terms of the outlook of around 17.5% or do you see a structural change in the business that might cause 16% to be the new norm?
Yes. Hey, George. Excellent job of reswizzling the question in a thoughtful way. So thank you for that. So again, I think that there's nothing structurally different in the business.
We're running it in a very similar way to the way we ran it, forever within Gartner, Again, we're very focused for 2020. Again, as we've talked about, around just making sure that our cost growth and our is aligned with our revenue growth. That's kind of step 1 in the process. If everything works, it goes well. Is there potential for some margin benefit?
Yes, we would say that absolutely. How much? We'll come back to you on that as we kind of get through this 1st phase, which is really making sure that we are aligned for 2020.
Thank you. This concludes today's question and answer session. I will now turn the call back to Jane Hall for closing remarks.
Well, as you heard today, we once again delivered strong performance across all three of our businesses, research, consulting and conferences. Gartner Formula for sustained long term growth continues to drive success in our research business. Our GTS organization continues to deliver strong GBS continued a path towards double digit growth and we expect GBS contract values to continue to accelerate. We delivered incredible value to every major function of the enterprise. We have a vast market opportunity.
We've made investments over the past few years that positions well to capture that market opportunity. And looking ahead to 2020, With the great strategic positioning of GTS and GBS, together with leveraging the investments we've made, we expect double digit top line growth and EBITDA growing approximately in line with revenues. For listening. We look forward to updating you again next quarter.
Ladies and gentlemen, this concludes today's conference call. Thank you for participating. You may now disconnect.
