Lauren Morris — Director of Investor Relations
Good morning and thank you for joining Metpace’s fourth quarter and full year 2025 earnings conference call. Also on the call today is our CEO August Trundle, our President Jesse Geiger, and our CFO Kevin Brady. Before we begin, I would like to remind you that our remarks and responses to your questions during this teleconference may include forward looking statements within the meaning of the Private Securities Litigation Reform act of 1995. These statements involve inherent assumptions with known and unknown risks and uncertainties as well as other important factors that could cause actual results to differ materially from our current expectations.
These factors are discussed in our Form 10K and other filings with the SEC. Please note that we assume no obligation to update forward looking statements even if estimates change accordingly. You should not rely on any of today’s forward looking statements as representing our views as of any date after today. During this call we will also be referring to certain non GAAP financial measures. These non GAAP measures are not superior to or replacement for the comparable GAAP measure, but we believe these measures help investors gain a more complete understanding of results. A reconciliation of such non GAAP financial measures to the most directly comparable GAAP measures is available in the Earnings Press Release and Earnings Call presentation slides provided in connection with today’s call.
The slides are available in the Investor Relations section of our website@investor.medpace.com with that, I would now like to turn the call over to August Kundal.
August Troendle — Chief Executive Officer and Chairman
Good day everyone. Cancellations were elevated again in Q4. Backlog cancellations in absolute and percent terms were the highest they’ve been in over a year. This resulted in a lower than anticipated net book to bill ratio of 1.04. The good news is that with a backlog conversion rate of 23.6%, our book to bill rate does not need to be very high to generate growth. I see no reason to expect the higher level of cancellations to continue but did not anticipate the spike in Q4. Only time will tell. Good opportunities continue to present themselves and I rate the overall business environment as adequate and headed in the right direction.
Jesse will now make some comments on Q4 and the year. Justin
Jesse J. Geiger — President
Thank you August. Good morning everyone. Revenue in the fourth quarter of 2025 was 708.5 million which represents a year over year increase of 32% and full year 2025 revenue was 2.53 billion, a 20% increase from 2024. Net new business awards entering backlog in the fourth quarter increased 39.1% from the prior year to 736.6 million resulting in a 1.04 net book to bill for the full year 2025, net new business awards were 2.65 billion, an increase of 18.7%. Ending backlog as of December 31, 2025 was approximately 3 billion, an increase of 4.3% from the prior year. We project that approximately 1.9 billion of backlog will convert to revenue in the next 12 months and our backlog conversion rate in the fourth quarter was 23.6% of beginning backlog.
With that, I will turn the call over to Kevin to review our financial performance in more detail and discuss our 2026 guidance. Kevin
Kevin Brady — Chief Financial Officer
Thank you Jesse and good morning to everyone listening in. As Jesse mentioned, Revenue was 708.5 million in the fourth quarter quarter of 2025. This represented a year over year increase of 32%. Full year 2025 revenue was 2.53 billion and increased 20% from 2024. EBITDA of 160.2 million increased 20% compared to 133.5 million in the fourth quarter of 2024. Full year EBITDA was 557.7 million and increased 16.1% from the comparable prior year period. EBITDA margin for the fourth quarter was 22.6% compared to 24.9% in the prior year period. Full year EBITDA margin was 22% compared to 22.8% in the prior year.
EBITDA margins were impacted by higher reimbursable cost activity driven by therapeutic mix. In the fourth quarter of 2025, net income of 1:35.1 million increased 15.5% compared to net income of 117 million in the prior year period. For full year 2025, net income was $451.1 million compared to $404.4 million in 2024 which represents an 11.6% increase. Net income growth below EBITDA growth was primarily driven by lower interest income compared to the prior year period as well as a slightly higher effective tax rate. Net income for diluted share for the quarter was $4.67 compared to $3.67 in the prior year period.
For the full year 2025, net income for diluted share was $15.28 compared to net income per diluted share of $12.63 in 2024. Regarding customer concentration, our top five and top ten customers represent roughly 25% and 35%, respectively, of our full year 2025 revenue. In the fourth quarter we generated $192.7 million in cash flow from operating activities and our net day sales outstanding was negative 58.7 days. As of December 31, 2025, we had 497 million in cash. For the full year 2025, we repurchased 2.96 million shares, or $912.9 million. At the end of the year, we had 821.7 million remaining under our share Repurchase Authorization program.
Moving now to Our guidance For 2026 full year 2026, total revenue is expected in the range of 2.755 billion to 2.855 billion, which represents gross of 8.9% to 12.8% over 2025 total revenue of 2.53 billion. Our 2026 EBITDA is expected in the range of 605 million to 635 million, representing growth of 8.5% to 13.9% compared to EBITDA of 557.7 million. In 2025, we forecast 2026 net income in the range of $487 million to $511 million. This guidance assumes a full year 2026 effective tax rate of 18.5% to 19.5%, interest income of 24.3 million, and 29.2 million in diluted weighted average shares outstanding for 2026.
There are no additional share repurchases in our guidance. Earnings per diluted share is expected to be in the range of $16.68 to $17.50. Guidance is based on foreign exchange rates as of December 31, 2025. With that, I will turn the call back over to the operator so we can take your questions.
Question & Answers
Operator
Thank you. As a reminder to ask a question, please press star 11 on your telephone and wait for your name to be announced. To withdraw your question, please press star 11. Again, in fairness to all, we ask that you please limit yourselves to one question and one follow up. One moment while we compile our Q and A roster. Our first question will come from the line of Max Mockwith William Blair. Your line is open. Please go ahead.
Christine Rains
Hi, great. It’s Christine Rainson for Max. Thanks for taking our questions. First one is what is embedded in your guidance for revenue growth excluding pass throughs last quarter? I believe you alluded to high single digit to low double digit direct fee revenue growth in 2026, but wondering if your growth expectations for this component are now higher given your strong EBITDA guide and also what you expect the cadence of this revenue growth to look like.
Kevin Brady — Chief Financial Officer
Yeah. Hi Christine, this is Kevin. We don’t provide guidance on direct service revenue. What I can tell you though is that from a reimbursable cost expectation, it’s consistent with what we shared back in October and that we expect it to be kind of in the 41 to 42% of revenue in 26. So slightly higher than what we finished here this year. From a quarterback cadence standpoint, you’re nothing I call out. In particular, I would say in terms of revenue. I do expect that reimbursable costs will start the year higher as a percentage of revenue than when we end the year.
And so that being said, I do expect maybe some flatter top line growth throughout the quarters than what we’ve experienced in past years.
Christine Rains
Great. That was really helpful context. I noticed the acceleration headcount growth in the quarter. What do you expect headcount growth to be in 2026? Should we expect this mid single digit growth cadence to continue or will you need an acceleration in hiring to support your 2026 outlook? Thanks.
Jesse J. Geiger — President
Hi, it’s Jesse. We do expect accelerated growth. We anticipate hiring in 26 to be above 25 levels somewhere in the mid to high single digit growth growth area.
Christine Rains
Great, thank you so much.
Operator
Thank you. And one moment for our next question. Our next question comes from the line of Justin Bowers with db. Your line is open. Please go ahead.
Justin Bowers — Analyst, Db
Hi, good morning everyone. Just was hoping can you sort of. Unpack the business environment and the commentary and the prepared remarks like either quantifying. RFP activity or win rates. And then also there seemed, you know. There was a pretty good funding quarter. In funding environment in the quarter as well. So can you just help us understand that.
August Troendle — Chief Executive Officer and Chairman
Business environment was, as I said, reasonably good. RFPs, if they matter, were up a bit both, you know, on the, you know, quarter over quarter and year over Year. But I, you know, I don’t think there’s anything really to call out beyond that. You know, it was a higher cancellation rate that led to us to miss. So our gross bookings have, again, substantially better than last year and I think doing fine overall.
Justin Bowers — Analyst, Db
Okay. Is there any way to help us. Understand if the cancellations were normal, what the. What sort of like the net bookings would be? And then with those cancellations was that, you know, could you help characterize those a bit more? Was it in, you know, any therapeutic area or, you know, customer area? Vintage?
August Troendle — Chief Executive Officer and Chairman
No. Cancellations were a little bit skewed towards metabolic area. That’s been growing quite a bit. So there were a higher level of cancellations there. Overall bookings have continued to be, you know, oncology are strongest. You know, metabolic still. Still there. But there were some elevated cancellations. So, you know, it was kind of otherwise relatively normal.
I don’t have a, you know, you know, we’re not providing, you know, what the booking would have been. You know, we don’t get gross bookings. We’re just, you know, netting them out. But, you know, the kind of, you know, directional magnitude of cancellations, but, you know, they would have been substantially higher if we had cancellations in a nice range.
Justin Bowers — Analyst, Db
Okay, thank you. I’ll jump back in queue.
Operator
Thank you. One moment for our next question. Our next question comes from the line of Ann Hines with Mizuho Securities. Your line is open. Please go ahead.
Ann Hynes — Analyst, Mizuho Securities
Thank you. I just want to ask some more questions on just the cancellations. Can you remind us what your historical. Range is and maybe what it was. This quarter versus maybe the heights that you saw in 2024 and early 2025? And again, I think the past few. Quarters, cancellations have been very stable. And is. Is this driven by, like, maybe the competitive environment, M and A. Is it widespread or is it just maybe one big client canceling something? So any more details would be great.
August Troendle — Chief Executive Officer and Chairman
Sure. Now it’s widespread. There was no single or couple of very large projects that canceled. It was just a higher level of cancellations. Overall. It, you know, comparable to the past year was. Was the highest level of cancellations at a backlog. If you combine backlog and, you know, kind of our entire portfolio, you know, I think Q1 was a little bit worse because we had such a high cancellation among projects that, you know, had been awarded but were not yet recognized and backlogged. But it was. It was a. It was a high level overall. And again, pretty, you know, widespread. I don’t know the. I have no, there was no pattern to it to discern. It was just kind of the usual random stuff that was very heavily concentrated.
Ann Hynes — Analyst, Mizuho Securities
And then your revenue growth, maybe. What are you assuming? Just for cancellation trends for the remainder of the year. And I know burn rate was very strong. Maybe. What’s the driver of that? And what are you assuming in guidance for the rest of the year for burn rate?
August Troendle — Chief Executive Officer and Chairman
We don’t guide the burn rate.
Kevin Brady — Chief Financial Officer
Right.
August Troendle — Chief Executive Officer and Chairman
Kevin, you want to say something?
Kevin Brady — Chief Financial Officer
Yeah. No. To August point, we don’t guide to a burn rate. It’s just not something that we do answer.
Ann Hynes — Analyst, Mizuho Securities
All right, thanks.
Operator
Thank you. One moment for our next question. Our next question comes from the line of David Winley with Jefferies. Your line is open. Please go ahead.
David Windley — Analyst, Jefferies
Hi, good morning. Thanks for taking my questions. August. I wanted to kind of philosophically ask around therapeutic area concentration. You mentioned oncology being very strong and metabolic right behind it. And as people have seen and you’ve highlighted, metabolic has been on this very steep growth ramp. I guess to me the difference between those two areas is like oncology is spread across tens, if not hundreds of different kind of micro indications. And metabolic seems to be very concentrated in diabetes and obesity. And so I wondered how you think about the concentration risk in metabolic and the crowding and the potential for cancellations like you apparently just saw, because people say we don’t have enough differentiation.
August Troendle — Chief Executive Officer and Chairman
Yeah. And, you know, another big area is mash, and there are, you know, few others that, you know, for us are meaningful. But yeah, it is, it is, you know, of late, you know, heavily kind of, you know, toward the obesity, diabetes area specifically. I, you know, I don’t think we’re at a level of over concentration that, you know, that’s a, that’s a big worry. It will be. Metabolic will be decreasing as a, you know, percent of our, you know, revenue next year, I think, you know, so I think it’s going to kind of somewhat normalize, you know, head towards a more normal range.
But I don’t really see that as. A. You know, a big risk for us at this time. Does that answer your question, Dave?
David Windley — Analyst, Jefferies
I think it does. Yeah. I think it does. Thanks. I guess in exploring the pass throughs, I think I understand that these metabolic trials carry relatively high pass throughs. And so it seems to track that your rapid growth in metabolic has also then contributed to the rapid growth in pass throughs as a percentage of revenue. And I think Kevin kind of referenced this and maybe, you know, the cancellation in metabolic is also what makes that moderate as you, as you go through the year. Is that right?
August Troendle — Chief Executive Officer and Chairman
Yeah, that’s absolutely right. I mean, in terms of, you know, pass throughs, they have been driven largely by our metabolic programs. And you know, we do expect them to, you know, start to normalize in this next year. And it does provide a, you know, headwind over overall revenue growth, but it’ll be more direct revenue, I guess, which is fine. So. Yeah, I think that’s correct.
David Windley — Analyst, Jefferies
Got it. And if I could just sneak one clarification on this end. To what extent like pastors have outstripped your expectations in 25, to what extent is kind of, is that underlying, like site level inflation and things like that that you’re, you’re having to re budget and add. And therefore those adjustments are kind of going directly into backlog and right into revenue. And kind of the pass through outstripping is what’s driving this higher burn rate. How much would you attribute to that?
August Troendle — Chief Executive Officer and Chairman
Almost none. I think this is not an issue of, you know, sites changing, getting more aggressive. You know, these were known to be very high pass through projects, you know, going in. You know, they’re just the design of the project is just very heavy on investigator fees. And you know, I, you know, our, I think the characteristics of the, you know, stage of the project and you know, what is, you know, what is burning overall in our backlog, you know, does cause our conversion rate to, you know, shift around quite a bit as we get other projects that don’t have as much, you know, relatively short duration.
High. You know, burn that are being added, you know, have been awarded, you know, quarter to quarter. But it’s not, I think, just the addition of pass throughs, you know, it’s the study itself, you know, has been opened up, you know, and there were some, you know, issues with, you know, recognizing it in backlog because of uncertainty of the program and stuff. You know, those relatively short term programs. Come on. Okay. You get a, you get awards and they burn rather quickly. You know, I think that will normalize over time and it is driven partly by the metabolic, you know, studies that we have, but not specifically because of, you know, a change in the expectation at sites.
David Windley — Analyst, Jefferies
Okay, thank you. Appreciate the extra question. Thanks.
Operator
Thank you. One moment for our next question. Our next question will come from the line of Charles Rahee with TD Cowan. Your line is open. Please go ahead.
Charles Rhyee — Analyst, TD Cowan
Yeah, thanks for taking the question. Maybe just two clarifications if I could. Kevin, you mentioned earlier that you expect pass through revenues to be higher at the start of the year than at the end of the year, does that suggest that you expect a lower metabolic mix as you exit 26? And then, you know, second question being maybe just a little bit of follow up to David’s question. You know, the way I understand, you know, how you think about, you know, what goes into backlog versus when you talk about stuff getting canceled out of pre backlog.
So if cancellations were broad based but elevated, you know, were these cancellations less about funding and, and maybe more from either trials failing or decisions by sponsors to abandon programs.
Kevin Brady — Chief Financial Officer
Maybe. I’ll take your first question, Charles, just in terms of reimbursables and you know, I do expect it to start the year higher. So yeah, to August comments, we do expect some of that metabolic shift to slow down a little bit. I wouldn’t say it’s materially so, but we do expect that to slow down a little bit. What was your second question, Charles?
Charles Rhyee — Analyst, TD Cowan
Oh, yeah, it’s just trying to understand, you know, you’ve talked about backlog versus pre backlog and my understanding was that pre backlog cancellations is, you know, perhaps more of a funding issue, but if something’s canceling out of backlog itself, that’s probably more of a, is that more of an issue that other trial maybe, you know, wasn’t successful or, and so was canceled or sponsors actually decide to abandon a program?
August Troendle — Chief Executive Officer and Chairman
Yeah, I mean that’s the case. Things that start up, they restructure, they change, they decide to end study early. So there were a number of studies ended early because of compound performance. So yeah, but I don’t think there was no pattern and it wasn’t just one or two very large projects.
Charles Rhyee — Analyst, TD Cowan
Okay, thank you.
Operator
Thank you. One moment for our next question. Our next question comes from the line of Sean Dodge with BMO Capital Markets. Your line is open. Please go ahead.
Sean Dodge — Analyst, BMO Capital Markets
Yeah, thanks. Good morning. Maybe just on guidance, if you could. Help us with some of the margin. Puts and takes at the midpoints, you have about 10 basis points of margin expansion for the year. And that’s despite, I know you all said accelerating hiring for the year, maybe a bit higher percentage for the year of pass throughs. How much pressure do you expect those to create? And then the offsets, is it just predominantly more productivity gains you can drive. And where those productivity gains expected to come from? Is it technology, offshoring, something else?
Kevin Brady — Chief Financial Officer
Yeah, just maybe just in terms of our guidance range, you’re kind of at the midpoint. It’s kind of normal cancellation rates. As Jesse mentioned, from a hiring perspective, we expect to be in the mid. The high single Digits, which is lower than the expectation on revenue growth. And so what’s driving that is just continued expectation that we continue to see good retention throughout 2026, which enables the productivity that we’ve seen throughout 2025 and exiting 2024. And so it enables us to hire higher but at a slower rate.
So it’s not that I would say that we’ve got major cost savings initiatives that are out there. We’re certainly not planning on restructuring. We always look for ways to operate in a more efficient way. And so that contributes to some of that margin improvement around the edge. But by and large it’s going to be driven by just slower hiring ability. On good retention.
August Troendle — Chief Executive Officer and Chairman
Utilization overall. We also have laboratory operations which are not huge, but utilization lab is up test. So it’s across the board. We’ve had good productivity.
Sean Dodge — Analyst, BMO Capital Markets
Okay. And then maybe just one on AI since perceptions around that have had a pretty big impact on the space over the last week or so. Just maybe. Any thoughts you can share on how. Big of a technological step change you. Think this is for the space over the next few years and then to. What extent you think that’s a longer term net positive or negative for medpace? And how are you all positioning? Are you a little bit more insulated? Just given the, you know, the kind of, the nature of your, your client base, how are you positioned for this? Are you investing around that?
August Troendle — Chief Executive Officer and Chairman
Yeah, I’ll address that a little bit. Look, I think it’s too early to know what, what kind of changes, you know, I do think that they will occur slowly. I would not anticipate really any productivity advantage, you know, overall net advantage to AI applications in 2026. And I think that’s not because we’re not rolling out and, and doing a lot of things in AI, it’s that I think the investment is going to at least equal the, you know, the benefits seen in, you know, in this first year of kind of, you know, rolling out applications.
You know, where this goes in terms of, you know, how much productivity enhancement there is, you know, in the long term and what that means to us. I mean, I do think that, you know, the productivity advances are, you know, going to be to the benefit, you know, part of it’s going to be rent to the providers of the models, et cetera. But you know, are going to be benefits to clients and you know, what, what that means in terms of, you know, encouraging, you know, more development, you know, et cetera. But you know, overall, you’d think on the surface of it, it’s net negative to, you know, a service company that, you know, makes, makes money by providing, you know, staff to, you know, perform work that is now, you know, made more efficient.
But I think that, you know, the timing of this, it’s going to take years, you know, just what that means, what the opportunities for us are, are, you know, are difficult to see. I don’t, I don’t really think we have, you know, you’d say barriers to prevent, you know, you know, I mean, we’re hoping to use AI in a lot of applications. We hope it does improve our productivity. And that means potentially in the long run, fewer staff than you’d otherwise have. And that means a little bit less revenue than you would have otherwise had.
At least net revenue.
Sean Dodge — Analyst, BMO Capital Markets
Okay, that’s very helpful. Thanks again.
Operator
Thank you. And one moment for our next question. Our next question comes from the line of Jaylen dressing with Trua Securities. Your line is open. Please go ahead.
Jailendra Singh
Thank you and thanks for taking my questions. So outside of cancellation spike you guys called out, did you also see any slowdown in decision making or business moving from pre backlog to backlog or within pre backlog. I’m sorry, changes between pre backlog and backlog?
August Troendle — Chief Executive Officer and Chairman
Yeah. In general, in terms of decision making, like our projects being getting delayed or like the way moving from pre backlog to backlog, is there a, is the business still moving at the same pace outside of cancellation? Look, I think things are moving along pretty well. There isn’t at least an incremental sudden change in the progression of nothing seizing up or anything like that. So I think things are relatively normal. You always have cases where some things are held or are slowed down for whatever reasons, you know, drug availability, you know, so they’re waiting on results of something.
There’s, you know, there’s always reasons why things can progress into backlog slower than anticipated. You know, they can change the design of the trial. You have to, you know, then rework things before you get it launched. But I don’t see any real trend there in terms of, you know, in the past sometimes we’ve seen a, because of funding, a seize up in a lot of things and prevents them from moving forward. We’re not seeing that at this time.
Jailendra Singh
Okay. And then my follow up, just in general about the competitive landscape, as you guys have called out about the top three CROs kind of getting more aggressive in the market. Have you seen them kind of continuing to get aggressive in terms of broadening their focus within biotech or in terms of price? Has that had any impact on your win rate. Just give us a little bit more flavor about the landscape in general with these top players getting the space.
August Troendle — Chief Executive Officer and Chairman
Yeah, I don’t think there’s anything to say there. I mean. I know they’re more aggressively interested in the space because they say they are, but they’ve been involved in the space all along and I don’t really see a large change in the dynamic. So it’s hard for me to know. I do not perceive a difference. We see the same competitors in the space and it seems to be the same as it was five years ago.
Jailendra Singh
Got it. Thank you.

Thank you. One moment for our next question. Our next question comes from the line of Dan Leonard with ubs. Your line is open. Please go ahead.
Dan Leonard — Analyst, Ubs
Thank you very much. My first question, it looked like from your disclosure that you had a pretty good quarter in large pharma revenue growth. Was there anything unusual to call out there and would that be sustainable?
Kevin Brady — Chief Financial Officer
Yeah, Dan, nothing to really call out. I think it might have changed a percentage point, but nothing to call out there. Not a focus. Large pharma is not a focus for us.
Dan Leonard — Analyst, Ubs
Thank you. And a follow up on that AI topic, August, you mentioned that 2026 is the first year you’re rolling out applications. Can you elaborate on that comment? What are you rolling out this year and what do you anticipate? You know, what are you trying to accomplish?
August Troendle — Chief Executive Officer and Chairman
Yeah, I don’t think we’re just going to. Jesse, do you want to, you want to comment on that?
Jesse J. Geiger — President
Yeah, I would just say in general, I mean, they fall into two categories, you know, one, just a number of different initiatives that are targeted on improving efficiency, you know, and that, you know, the blurry line between like, what do you call AI improvement that’s really, you know, tech enabled support for different things across the organization that are focused in that category. And then the other category would be, you know, assisting with data analytics for feasibility, site selection and helping the team there with some AI enabled tech. That’s where we’re starting.
Dan Leonard — Analyst, Ubs
Thank you very much.

And one moment for our next question. Our next question will come from the line of Luke Surgat with Barclays. Your line is open. Please go ahead.
Luke Sergott — Analyst, Barclays
Great. Thanks for the question here. I just wanted to kind of follow up on Dave and kind of the margin questions. So. Can you help us understand the near term levers that you have to pool as a project starts to ramp on? And what I really want to get at is let’s assume you get some type of booking a year ago and your assumption is that these are the types of resources that you’re going to need to execute this trial. And as that ramps, it starts to either come out that you can actually use less resources or more resources. I just want to understand like your flexibility to ramp here. And this is, I think important as you think about the overall mix of the bookings and how this has changed from a burn rate and capacity needs as you get, you know, as metabolic and the like continue to gain share.
Kevin Brady — Chief Financial Officer
Yeah, I mean in terms of our. You just remember that in terms of our business model, we like to hire ahead because we are a training shop. We like to train and develop our people. And when you’ve got larger attrition rates, right. You’re having to replace those individuals that you’re leaving plus onboard new people. And so we’ll. What we’ve seen over the last year or so is that with improved retention rates, you’re having to do less of that training. You’re only training the ones that are coming in. And because of that you’re seeing more improved productivity because you’re spending less time on training and development and you’ve got more experienced individuals and staff that are on site.
So we continue to operate under the, that business model of hiring ahead and we’ll continue to do that. But it’s at levels that are, that are less than what we had to do two years ago. So what you’re seeing is that productivity and that improved utilization continue to play through for us.
Luke Sergott — Analyst, Barclays
All right, great. And then I guess from your performance obligations over the last that are over three years long have continued to kind of trend down here off of like your peaks of for Q24 soon. Obviously most of this probably due to the faster burning business.
But anything else going here? Is there a change in the duration of these trials or the type of work that’s going on?
August Troendle — Chief Executive Officer and Chairman
It certainly was an average change in the duration of our trials because we had this substantial ramp in metabolic trials and a number of trials overall that were shorter. But that changes over time. I don’t think there’s a change in a particular class of trial. I just think it’s a change in the mix of trials that we’ve had, you know, in the last few years, last year particularly. But I don’t think there’s a long term trend in terms of trial duration changing for a given indication and you know, stage of a trial.

I don’t think pricing is, you know, our pricing on net is changed materially over time. So I don’t, you know, I don’t think it should have a, you know, impact on margin. I think our margin is going to be maintained. Yeah. I mean, given all the other factors, it’s not going to be a driver of a margin change.
Daniel Clark — Analyst, Ubs
Okay, got it. Thank you. And then just one more on. On AI. When you’re talking to customers or involved in RFPs, what are they kind of focused on, if anything, from an AI angle? Thank you.
Jesse J. Geiger — President
I was going to say it’s a balanced conversation because we do take a very measured approach to AI. We want to balance the benefits with risk management and ensure that A, we have quality adoption and B, that we’re not putting any of their information at risk. And so the conversations are kind of twofold. One, what are we doing with AI to help with their studies and at the same time, how are we being good stewards of data to make sure that we continue with high quality and confidentiality?
Operator
All right, thank you. And one moment for our next question. Our next question comes from the line of Jay Lewis with Baird. Your line is open. Please go ahead.
Jay Lewis — Analyst, Baird
Hey, thanks. Appreciate the question. I was wondering if you could give us any more color on the new signings in the fourth quarter, that tranche of business that would have largely moved into your pre backlog. And could you give any quantification on that pre backlog and maybe how much it’s up year over year, quarter over quarter?
August Troendle — Chief Executive Officer and Chairman
Yeah, we don’t provide, you know, details on that. Q4 was a bit light on, as was the prior Q4, but we don’t give exact magnitude on that.
Jay Lewis — Analyst, Baird
Okay, and then could you speak to the impacts that you’ve seen from this accelerating M and A environment with Large Pharma buying your clients and any impacts that may have had on your revenue, your bookings, or your future revenue projections?
August Troendle — Chief Executive Officer and Chairman
I’m sorry, what would have a steel.
Jay Lewis — Analyst, Baird
Impact, the accelerating M and A environment with, with large pharma buying some of your clients?
August Troendle — Chief Executive Officer and Chairman
Yes, it’s obviously a potential. Our clients, you know, a number of our clients have been purchased in the past year. They continue to be, but we have a pretty broad, you know, base of clients. So I, you know, I don’t anticipate that to be a, an issue generally. We don’t lose the work that we’re doing with the client. We generally lose the client long term. We get incorporated into a large pharma, but it’s generally not a short term risk. But it happens, not infrequently.
Jay Lewis — Analyst, Baird
Good. Thank you.
