Good day, ladies and gentlemen, and welcome to the Medpace Fourth Quarter and Full Year 2025 Earnings Conference Call. (Operator Instructions) As a reminder, this call is being recorded. I would now like to introduce your host for today's conference call, Lauren Morris, Medpace's Director of Investor Relations. You may begin.
Lauren Morris - Director of Investor Relations
Good morning, and thank you for joining Medpace's Fourth Quarter and Full Year 2025 Earnings Conference Call. Also on the call today is our CEO, August Troendle; our President, Jesse Geiger; and our CFO, Kevin Brady. During this teleconference, we 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 10-K 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 a replacement for the comparable GAAP measures, but we believe these measures help investors state 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 at investor.medpace.com.
With that, I would now like to turn the call over to August Troendle.
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
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 our rate to the overall business environment is adequate and headed in the right direction. Jesse will now make some comments on Q4 and the year. Jesse?
Jesse 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, Treasurer
Thank you, Jesse, and good morning to everyone listening in. As Jesse mentioned, revenue was $708.5 million in the fourth 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 $135.1 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 per diluted share for the quarter was $4.67 compared to $3.67 in the prior year period. For the full year 2025, net income per diluted share was $15.28 compared to net income per diluted share of $12.63 in 2024. Regarding customer concentration, our top 5 and top 10 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 days 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 for $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 growth 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.
Operator
(Operator Instructions) Our first question will come from the line of Max Smock with William Blair. Your line is open, please go ahead.
Christine Rains - Analyst
It's Christine Rains on for Max. 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, Treasurer
Yes. 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 in 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 quarterly cadence standpoint, nothing I'd 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 - Analyst
Okay. That was a really helpful context. I notice here the acceleration in head count growth in the quarter, what do you expect head count 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?
Jesse Geiger - President
Hey, 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 area.
Christine Rains - Analyst
Great, thank you so much.
Operator
Our next question comes from Justin Bowers with DB. Your line is open, please go ahead.
Justin Bowers - Analyst
Hi, good morning, everyone. Just was hoping, can you sort of unpack the business environment and the commentary in the prepared remarks, like either quantifying RFP activity or win rates? And then also, there was a pretty good funding environment in the quarter as well. So can you just help us understand that?
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
Business environment was, as I said, reasonably good. RFPs, if they matter, were up a bit, both on quarter-over-quarter and year-over-year. But I don't think there's anything really to call out beyond that. It was a higher cancellation rate that led to us to miss our gross bookings have again substantially better than last year and I think doing fine overall.
Justin Bowers - Analyst
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 could you help characterize those a bit more? Was it in any therapeutic area or customer area, vintage?
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
No. Cancellations were a little bit skewed towards metabolic area, it's been growing quite a bit. So there were a higher level of cancellations there. Overall bookings have continued to be -- oncology are our strongest, metabolic still there, but there were some elevated cancellations. So it was kind of otherwise relatively normal.
I -- we're not providing what the booking would have been -- we don't give gross bookings, we're just netting them out kind of directional magnitude of cancellations, but they would have been substantially higher if we had cancellations in a nice range.
Justin Bowers - Analyst
Okay, thank you. I'll jump back in queue.
Operator
Our next question comes from the line of Ann Hynes with Mizuho Securities. Your line is open, please go ahead.
Ann Hynes - Analyst
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 in the past few quarters, cancellations have been very stable. Is this driven by like maybe the competitive environment, M&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 & Chairman of the Board of Directors
Sure. It's widespread. There was no single or a couple of very large projects that canceled. It's just a higher level of cancellations overall. Comparable to the past year, it was the highest level of cancellations out of backlog.
If you combine backlog and kind of our entire portfolio, I think Q1 was a little bit worse because we had such a high cancellation among projects that had been awarded but were not yet recognized in backlog. But it was a high level overall. And again, pretty widespread. I don't know the -- I have no -- there's no pattern to it to discern. It was just kind of the usual random stuff that was very heavily concentrated.
Ann Hynes - Analyst
And then your revenue growth, maybe what are you assuming just the cancellation trends for the remainder of the year? And I know burn rate is 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 & Chairman of the Board of Directors
We're not going to guide to burn rate. Right, Kevin, do you want to say something?
Kevin Brady - Chief Financial Officer, Treasurer
Yes. No. We -- to August point, we don't guide to burn rate. It's just not something that we do, Ann.
Operator
Our next question comes from the line of David Windley with Jefferies. Your line is open, please go ahead.
David Windley - Analyst
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 microindications, 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 & Chairman of the Board of Directors
Yes. And another big area is NASH. And there are a few others that for us are meaningful. But yes, it is a late heavily kind of toward the obesity, diabetes area specifically. I don't think we're at a level of over concentration that that's a big worry.
It will be -- metabolic will be decreasing as a percent of our revenue next year, I think. So I think it's going to kind of somewhat normalize heading towards more normal range, but I don't really see that as a big risk for us at this time. Does that answer your question, Dave?
David Windley - Analyst
I think it does. Yes, I think it does, thanks. I guess 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 the cancellation in metabolic is also what makes that moderate as you go through the year. Is that right?
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
Yes, that's absolutely right. I mean in terms of pass-throughs, they have been driven largely by our metabolic programs. And we do expect them to start to normalize in this next year. And it does provide a headwind to overall revenue growth, but that will be more direct revenue, I guess, which is fine. So yes, I think that's correct.
David Windley - Analyst
Got it. And if I could just sneak one clarification on this end. To what extent -- like pass-throughs 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 having to rebudget 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 & Chairman of the Board of Directors
Almost none. I think this is not an issue of sites changing, getting more -- it is we're known to be very high pass-through projects going in. They just -- the design of the project is just very heavy on investigator fees. And our -- I think the characteristics of the stage of the project and what is burning overall in our backlog does cause our conversion rate to shift around quite a bit as we get other projects that don't have as much relatively short duration, high burn that are being added have been awarded quarter-to-quarter, but it's not, I think, just the addition of pass-throughs. It's the study itself has been opened up.
And there were some issues with recognizing it in backlog because of uncertainty of the program and stuff. And those relatively short-term programs come on, okay, you got to get awards and they burn rather quickly. I think that will normalize over time, and it is driven partly by the metabolic studies that we have, but not specifically because of a change in the expectation at sites.
David Windley - Analyst
Okay, thank you.
Operator
Our next question will come from the line of Charles Rhyee with TD Cowen. Your line is open, please go ahead.
Charles Rhyee - Analyst
Hi, thanks for taking my 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 lower metabolic mix as you exit '26? And then second question being -- and maybe just a little bit of a follow-up to David's question. The way I understand how you think about that -- what goes into backlog versus when you talk about stuff getting canceled in our pre-backlog.
So cancellations were broad-based, but elevated. Were these cancellations less about funding and maybe more from other trials failing or decisions by sponsors to abandon programs?
Kevin Brady - Chief Financial Officer, Treasurer
Maybe I'll take your first question, Charles, just in terms of reimbursables, and I do expect it to start the year higher. So yeah to Augustâs 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 it to slow down a little bit. What was your second question, Charles?
Charles Rhyee - Analyst
Yes. I was just trying to understand, you talked about backlog versus pre-backlog. And my understanding was that pre-backlog cancellations is perhaps more of a funding issue. But if something is canceling out of backlog itself, that's probably more of a -- is that more of an issue that other trial maybe wasn't successful or -- and so is canceled, or sponsors actually decide to abandon a program?
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
Yes. I mean that's the case. Things that start up a restructure, they change, they decide to end a study early. So there were a number of studies ended early because of compound performance. So yes, but I don't think there was no like pattern, and it wasn't just one or two very large projects.
Operator
Our next question comes from the line of Sean Dodge with BMO Capital Markets. Your line is open, please go ahead.
Sean Dodge - Analyst
Thanks, good morning. Maybe just on guidance, if you could help us with some of the margin puts and takes. At the midpoint, 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 pass-throughs. How much pressure do you expect those to create? And then the offset, is it just predominantly more productivity gains you can drive and then where are those productivity gains expected to come from? Is it technology, offshoring, something else?
Kevin Brady - Chief Financial Officer, Treasurer
Yes. Just -- and maybe just in terms of our guidance range, you're kind of at the midpoint, it assumes kind of normal cancellation rates. As Jesse mentioned, from a hiring perspective, we expect to be in the mid to 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, 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 the margin improvement around the edges. But by and large, it's going to be driven by just slower hiring ability on good retention.
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
And utilization overall. We also have laboratory operations, which are not huge, but utilization in lab is up test. So it's across the board. We've had good proven activity.
Sean Dodge - Analyst
Yes. 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 kind of the nature of your client base? How are you positioned for this? Are you investing around that?
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
Yes. I'll address it a little bit. Look, I think it's too early to know what kind of changes. I do think that they will occur slowly. I would not anticipate really any productivity advantage, overall net advantage to AI applications in 2026.
And I think that's not because we're not rolling out and doing a lot of things in AI. It's that I think the investment is going to at least equal the benefits seen in this first year of kind of rolling out applications. Where this goes in terms of how much productivity enhancement there is in the long term and what that means to us. I mean I do think that the productivity advances are going to be the -- part of it's going to be rent to the providers of the models, et cetera, but are going to be benefits to clients. And what that means in terms of encouraging more development, et cetera.
But overall, youâd think on the surface of it, it's negative to a service company that makes money by providing staff to perform work that is now made more efficient. But I think that the timing of this, it's going to take years. Just what that means, what the opportunities for us are difficult to see. I don't really think we have, say, barriers to prevent. 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 weâd otherwise have, and that means a little bit less revenue than you would have otherwise had, at least net revenue.
Operator
Our next question comes from the line of Jailendra Singh with Truist Securities. Your line is open, please go ahead.
Jailendra Singh - Analyst
So outside of cancellations spike you guys called out, did you see any slowdown in decision-making or business moving from pre-backlog to backlog within pre-backlog?
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
I'm sorry, changes between pre-backlog and backlog?
Jailendra Singh - Analyst
Yes, in general, in terms of decision-making, like are projects being getting delayed or like the way moving from pre-backlog to backlog. Is that -- is the business still moving at the same pace outside of cancellation?
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
Look, I think things are moving along pretty well. There isn't at least incremental sudden change in the progression of product; 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, drug availability, some they're waiting on results or something. There's always reasons why things can progress into backlog slower than anticipated.
They can change the design of the trial, you have to -- then rework things before you get it launched. But I don't see any real trend there in terms of -- in the past, sometimes we've seen, because of funding, a seize up in a lot of things that prevents them from moving forward. We're not seeing that at this time.
Jailendra Singh - Analyst
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 be aggressive in terms of broadening their focused 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 & Chairman of the Board of Directors
Yes. 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 5 years ago.
Jailendra Singh - Analyst
Alright, thank you.
Operator
Our next question comes from the line of Dan Leonard with UBS. Your line is open, please go ahead.
Dan Leonard - Analyst
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, Treasurer
Yes, Dan, nothing to really call out. I think it might have changed a percentage point, but nothing to call out there. It's not a focus, large pharma is not a focus for us.
Dan Leonard - Analyst
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? What are you trying to accomplish?
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
Yes. I don't think we're just going here. Jesse, do you want to comment on that?
Jesse Geiger - President
Yes. I would just say, in general, I mean, they fall into two categories. One, just a number of different initiatives that are targeted on improving efficiency, and that -- the blurry line between like what do you call [inaudible] that's really tech-enabled support were different things across the organization that are focused in that category. And then the other category would be assisting with data analytics for feasibility, site selection, and helping the team there with some AI-enabled tech. That's where we're starting.
Operator
Our next question will come from the line of Luke Sergott with Barclays. Your line is open, please go ahead.
Luke Sergott - Analyst
Thanks for the question. I just wanted to kind of follow up on Dave and the kind of the margin questions. So as we like -- can you help us understand the near-term levers that you have to pull as the 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 -- as metabolic and the like continue to gain share?
Kevin Brady - Chief Financial Officer, Treasurer
Yes. I mean in terms of our -- just remember that in terms of our business model, we like to hire heads 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 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 that business model of hiring ahead, and we'll continue to do that, but it's at levels that are less than what we had to do 2 years ago. So what you're seeing is that productivity and that improved utilization continue to play through for us.
Luke Sergott - Analyst
All right. Great. And then I guess from performance obligations over the -- that are over 3 years long, have continued to kind of trend down here off of like your peak of 4Q '24. I assume obviously that most of this probably do with the faster burning business. But anything else going here is like, is there a change in the duration of these trials or the type of work that's going on?
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
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 kind of 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 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 stage of a trial.
Luke Sergott - Analyst
Great, thanks.
Operator
Our next question will come from the line of Michael Cherny with Leerink Partners. Your line is open, please go ahead.
Daniel Clark - Analyst
Great, thank you. This is Dan Clark on for Mike. Just wanted to ask about pricing. How did that look in your new awards in 4Q? And how are you thinking about that for 2026?
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
I don't think pricing is -- our pricing on net has changed materially over time. So I don't think it should have an impact on margin. I think our margin is going to be maintained. I mean, given all the other factors, it's not going to be a driver of a margin change.
Daniel Clark - Analyst
Okay. Got it, thank you. And then just one more 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?
Jesse Geiger - President
I was going to say it's a balance 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.

Our next question comes from the line of Jay Lewis with Baird. Your line is open, please go ahead.
Jay Lewis - Analyst
Hey, thanks, appreciate for 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 & Chairman of the Board of Directors
Yes. We don't provide 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
Okay. And then could you speak to the impacts that you've seen from this accelerating M&A environment with the large pharma buying your clients and any impact that may have had on your revenue, your bookings over your future revenue projections?
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
I'm sorry, that what would have impact?
Jay Lewis - Analyst
Yes, accelerating M&A environment with large pharma buying some of your clients?
August Troendle - Chief Executive Officer & Chairman of the Board of Directors
Yes. It's obviously a potential. Our clients -- a number of our clients have been purchased in the past year and will continue to be. But we have a pretty broad base of clients. So I don't anticipate that to be an issue. Generally, we don't lose the work that we're doing with the client.
We generally lose the client long term, and they get incorporated into a large pharma. But it's generally not a short-term risk, but it happens not infrequently.
Operator
Thank you. And I would now like to hand the conference back over to Lauren Morris for closing remarks.
Lauren Morris - Director of Investor Relations
Thank you for joining us on today's call and for your interest in Medpace. We look forward to speaking with you again on our first quarter 2026 earnings call.
Operator
This concludes today's conference call. Thank you for participating. You may now disconnect. Everyone, have a great day.
