If we can establish them in the U.S.
So having avoided talking about Mach49, I now devote an entire slide to it. This is really just an attempt to make sure that everybody understands where all of this came from and where it should be going forward.
As a little bit of a reminder, we bought them back in 2020, paid $4.7 million at that time. They were a relatively small business. We also paid a relatively small economic interest of 25%. Normally, we pay a higher level. That was simply because at the time, they did feel much more like a start-up to us, and it was very unclear what their growth pattern would be. And so there was some logic to that.
You fast forward a little less than 2 years and you find them then winning this monstrous contract, which at the time, there was talk of it being possibly up to 10 years. We thought that, that was a little long to contract anything for as did the client. It contracted for 5 years with very specific services through every single one of those years. It was written very much in that way.
We will, at the end of this year, have generated roughly $124 million in after-tax profits. From them, we will have paid out $127 million. So essentially, pretty much a wash. What we have going forward, though, is an obligation to pay a further $105 million. But that's against a business that I think next year is going to do sort of [ GBP 9 million, GBP 10 ] million of EBIT.
As an acquisition, if you were looking at it, you would say to yourself, that's not terrible, maybe not quite the deal that we thought we were going to get at a particular point in time, but it's still not an awful situation. We also have these rather strange tax benefits that the U.S. gives that Peter understands far better than I do, which means you basically get over a fairly protracted period of time, a reduction in your tax payments for the group.
If you take all of that into account, that means that from here, we would expect an 8-year payback, which, again, for most acquisitions for us is about typical. That's sort of where we would normally expect things. But in terms of the business health, as Peter said, it had a not brilliant first half, but things have certainly looked much, much better over the summer. And I do think that now that they know that the big contract is going away, management is going to be extraordinarily focused on one thing and one thing alone, which is growing what we always described as the core. They didn't like it when we described it as classic.
In terms of operational progress, we described it as the next Next 15. Earlier this year, we spent a lot of time with the Board sort of really trying to dig in and analyze like where do we go from here? What is wrong with our business that we could improve, what is right with our business that we could accelerate? How could we make our business more valuable? Basically, how could we make it a better business? What that spat out was a number of different things.
This is really just a summary of some of the highlights, not all of them. We can't avoid AI. We absolutely cannot. We've made significant progress in AI, as I'll come on to talk about. But it's one of those things, the less you do now, the more you will have to do later or the greater the risk the business faces going forward. The option to do nothing and spend no money is not really an option if you want to remain a viable business in our sector.
Our current operating model, which is we buy businesses, we add businesses to the portfolio is having this sort of rather a wonky effect of then just basically scaling head office, which long term is unsustainable. The number of businesses that reporting to Peter and I are pretty significant. We have taken steps to start to prune that. But we can see the operating model is becoming increasingly inefficient in certain areas. We are taking steps to improve that.
Our structure also does not optimize for client synergies. We have an awful lot of customers where we work with them in multiple parts of our business, and we are not getting the benefit from that. We are not as joined up as we need to be. A few years ago, we talked about this. We made some efforts in there, but then we got super busy and our efforts went away. I think you will see those efforts massively redoubled. And with the simplification of the model, that will also help dramatically.
And lastly, you guys just are clueless on what our business does. A number of times, we sit and talk to you and you say, I find this part of your business really confusing, and we kind of go, but we understand that. I mean it is confusing. We are a very complicated business for our size, and we need to solve that. There's no doubt about it.
Looking sort of forward, we do know that our decentralized model works. We know that it creates fantastic local accountability. So you're not going to see us just suddenly say, right, we're going to become [indiscernible] with one P&L and that kind of thinking. What you will see is a reduction in the number of what we would call significant businesses within the organization.
So there will be -- I think by the early part of next year, we're aiming to get that from -- depending on how you calculate it today, 21% or 19% is the different calculation down to 12%. I think there's scope to do more than that in the longer term, but that would see the business reshape quite significantly. A good example is SMG and Plinc. Those 2 businesses are very complementary. And if you look at SMG's sort of trajectory as a business, it's increasingly can see itself as a software and services business.
And Plinc's software is a fabulous product for them to sell and a very complementary product for them to sell. And the management teams of both businesses seem pretty excited by that, and we anticipate those 2 businesses merging by the end of this year. There are lots of examples like that across the group where we can see very complementary business sets, very complementary cultures and skills, and that word culture is very important to us because we know that culture eats strategy for breakfast every day.
If you try and merge 2 businesses with different cultures, be prepared for a pretty awful time period where those businesses just try and eat each other in front of your eyes. AI, I mentioned that we're making a lot of progress. We have a what feels like gazillion projects going across the business to do with AI. Some of them are tiny. Some of them are really quite simple little exercises. Some of them are really quite meaty. We talked last time we were in this room about synthetic personas and maestro.
Those 2 projects have really evolved in a pretty significant way and are now actually being further developed by individual businesses within the group, if you like, the Next 15 labs part of our organization, which sits in head office has sort of done the bulk of its work and now the challenge is within the individual businesses for them to put that to work. But I saw a demonstration from one of our businesses that's taken on personas this week, and it's very impressive what it can do. And it is creating completely new revenue streams for those businesses.
SMG, can I say them enough in this meeting. I'm not trying to overshadow Mach49, but SMG is -- has also done a pretty impressive level of AI development, in particular relation to Plan Apps. It creates a much more sophisticated campaign planning tool. And I think given that their future very much lies in their ability to put software at the heart of the business, that's deeply encouraging.
As I've mentioned, combining to create scale, that's very much the path for the business. In practice, what that breaks down into is how do we drive growth and how do we save money. Driving growth is us continuing to invest in new areas. Retail media is obviously big for us. Influencer marketing, I can see as being another big growth area for us. The other bits I've really already talked about. Cost control is -- you could say head office simplification, I think there is definitely scope there as we move forward.
We do an awful lot of work for the brands. So that line between us and the brands can sometimes get a little blurry. I think we need to bring that much a little bit more into focus. We focus a lot on gross margins. I think we'll also focus a lot on revenue per head, especially as AI really kicks in. The real risk for us is that we embed AI and see our revenues decline. That absolutely cannot happen. And so pricing is going to be crucial in that respect. But there is huge scope for offshoring and automation going forward.
I talked about these 130 AI projects. A lot of those are clever little ways of being able to do something in a fraction of the time. A good example is we have to do across our comms businesses, a lot of media monitoring, basically listening to see what is being said about a particular company. It takes days to produce that work if you do it manually because especially for a big company, there are hundreds and hundreds of pieces of content coming through and you have to weed out all the ones that are actually not them. There's some other company with a similar name in a completely different industry, ones that are just so minor and mentioned that you shouldn't include it. It's one of those incredibly boring tasks, but incredibly important that you get it right tasks.
In other words, if you screw that up, look really bad to your customer because that analysis is extremely important. We have developed an AI solution for that. And basically, it takes that 2 or 3 days down to about an hour. Now for the customer, the value of that has not changed. And this is where I talked about pricing being crucial. We have to be able to deliver that solution and charge the customer even though we could do it better, much faster, we have to make sure that the client then doesn't say, oh, well, it only took you an hour, therefore, I only want you to charge me for an hour. So the packaging and the pricing for those things is very important to us.
In terms of the trading environment, the earlier-than-anticipated election definitely impacted us. We expected the first half to be down. We knew we'd had a pretty tough comp from particularly the Department of Education, which is one of our largest customers. And we knew that they spent disproportionately in the first half of last year. As I say, we kind of knew this was always going to be a bit of a rough comp, but government most definitely shut down much more quickly than anticipated.
We don't anticipate that coming back in the second half. We do expect it to come back in the first part of next year. We are already seeing a bit more normalization in that area. But in truth, the government works slowly. And so it will be a little while before the frameworks really open up and the revenues that go with that. If you look beyond that, if we didn't do technology, public sector isn't that huge from a revenue perspective for us.
You would have seen us produce some pretty impressive results, very strong organic growth in those different sectors. Now that's what leads to a lot of frustration on our end, which is all that really needs to happen is tech to stabilize, and then our numbers are suddenly going to look really dramatically better because we really don't see the trends in those other areas slowing down. Health care should continue to be a nice growing market for us. We have a very high-quality business in particular in that space.
Public sector, we know will rebound. Consumer passions continue -- consumer passion is really FMCG plus sport, plus a few other things. It's shampoo, it's dog food. It's all sorts of stuff that people buy. And it's a very, very strong business for us. And again, we have some excellent businesses in that space. So I don't see that changing. If I then move on to a little bit about client analysis, what's going on. We had a number of people say, oh my God, you lost this huge customer. What else do you have that I haven't really factored in?
And the answer is, actually, if you look at our top 20, it stayed incredibly stable. This says that the client retention is 7 years. That's actually distorted by the fact that people like Asda and Boots and Morrisons have come in relatively recently. They are new additions that have come in and made that look like we only keep our clients for 7 years. If you take them out, then it rapidly goes up into double digits.
Our story is very, very good. We don't have high client concentration, but we do have very high client retention. And we do continue to add good customers with notable revenue streams, and we continue to expand customers. We've listed 2 here in the FMCG market, Johnson & Johnson, Procter & Gamble. Procter & Gamble is going to be in our top 10, pretty certain of that. If not, it will certainly be in the second half and certainly next year. I think it will comfortably in that space.
Peter mentioned that we'll continue to do some acquisitions, 2 little ones for MHP and La Plage and sort of actually weirdly takes them into tech, but in a relatively niche way. La Plage is essentially a digital content business and is making a very good addition to that organization growing very nicely.
Hayden's Innova is the most recent. It didn't quite fit really into the first half, certainly didn't have any impact on the first half. That's an expansion of our capabilities in the business transformation area under transform. They also do a lot of government contract work. I think the biggest client in that area is in the health care, NHS effectively area. It's a very good business, but we have not paid huge multiples for any of these things, as you can see.
We did have a number of customers say to us, I assume acquisitions are off the table because your multiple is so low. Well, if we can buy businesses at this multiple, we'll carry on doing it because it's still quite accretive for us. Certainly, in the long term, it's good for us. As it says at the bottom here, the annualized impact next year for all of these things is GBP 21 million. So not huge, but not nothing.
Ending on the outlook, if I couldn't say this, I would deserve not to be sitting here. We are confident of meeting the expectations that were reset very recently. I think if there is an improvement in the tech market that is earlier than anticipated, then I would hope that we would do better. But at this stage, it feels like we shouldn't be trying to predict anything like that. We remain on the naughty step. We are working hard to get [ out of it ].
