[Dan Batrack, Chairman & Chief Executive Officer]

Great. Thank you very much, Darryl. And good morning, and welcome to our fiscal year 2023 first quarter's earnings conference call. We had an excellent first quarter and start to our 2023 fiscal year, setting new records for net revenue, our operating income and earnings per share.

In the quarter, our EBITDA margin exceeded 14% for the first time in our history. Backlog, the best indicator of future growth for us, achieved an all-time high of $3.81 billion, up 11% from last year. And just as the first quarter closed, we announced the acquisition of Amyx, bringing 500 high-end security cleared staff to our US federal IT practice.

And more recent, back just 10 days ago, we completed our acquisition of the RPS Group that adds 5,000 staff and provides new growth opportunities, especially in international water and energy consulting business.

I'll begin today's presentation with an overview of our first quarter results and the business outlook, while Steve Burdick, our Chief Financial Officer, will provide additional details of our financial performance and capital allocation. Jill Hudkins, our President will also provide additional insight into our strategic growth opportunities that we see together with RPS.

We had a very strong first quarter, setting new records for net revenue, operating income, adjusted earnings per share and backlog. Our net revenue was $737 million in the quarter, up 8% from the prior year, a new all-time high for any quarter in the company's history.

We also had a record 14% adjusted EBITDA margin, which is 90 basis points increase from the prior year. As a result of this increased margin, we generated an operating income of $97 million for the company, up 17% year-over-year.

Earnings per share from operations were a record $1.34 for the quarter. First time we've ever ceded $1.30, up 20% from last year on an equivalent tax basis. And in fact, we were well over $2 on a GAAP basis of earnings per share in the quarter.

I'd now like to provide an overview of our performance by our end customer. In the first quarter, our growth was driven by strong performance across all four of our key client sectors. Our US Commercial net revenue was the fastest-growing sector in the company with net revenue up 22% year-over-year and comprised about a quarter of our overall business. The commercial growth was driven by strong performance in high-performance buildings, environmental restoration and a very fast-growing area in renewable energy services.

Work for our US Federal clients was up 10% year-over-year and represented 28% of our net revenue in the quarter. The increase in our US Federal work was driven by a very broad-based increases across all of our key government clients, but it was especially driven by civilian agencies for the US Federal government such as the Environmental Protection Agency, US State Department and the US Agency for International Development.

Our state and local revenues for municipal, water, infrastructure and planning services grew at a 10% rate year-over-year this quarter with continued strong demand for our best-in-class water supply and watershed management solutions. This 10% growth builds on our seven consecutive years of double-digit growth in the state and local markets here in the United States.

Our International net revenue was up 13% year-on-year on a constant currency basis, driven by growth in water, environmental and sustainable infrastructure work, primarily in the countries of Canada, Australia and the United Kingdom.

I'd now like to present our performance by our two segments. Our GSG and our CIG segments, both grew in the first quarter as a result of broad-based demand for our high-end services.

I'll start with the GSG segment or the Government Services Group segment, which was up 8% and year-over-year with the growth in water and environmental programs. Our GSG segment delivered a record 17.1% margin, up 240 basis points from last year.

This record margin was a result of really three different things. First, continued business shift in our mix to higher-margin services. Second, favorable project close-outs and really project performance. And third, higher utilization in the quarter.

We had especially strong utilization for US Federal work and our disaster recovery services for responding to Hurricane Ian, which impacted Florida really just coming into the quarter during the month of October and extending through November and December.

Without the extraordinary margin contributions from these project close-outs and episodic disaster work, we really would have seen about a 15% margin in the GSG segment for the quarter and it's probably more representative of an ongoing margin for that particular segment.

The CIG segment grew by 9% year-on-year and delivered a 13.1% margin in the quarter, up 60 basis points from last year in line with our expectations. This is the fifth consecutive quarter with a year-on-year margin expansions for the CIG segment.

The margin expansion in the first quarter was driven by strong utilization in high-performance buildings, environmental programs and renewable energy services across our global operations.

Backlog at the end of the quarter was up 11% year-on-year, resulting in an all-time high ending value of $3.81 billion for the company. In the first quarter, we won many new programs and task orders with both our commercial and government clients here in the United States and internationally.

We leveraged our $25 billion value in contract capacity with the US federal government, and our existing master service agreements, to generate almost $1 billion in new orders just in the quarter.

We were also awarded new programs such as the $42 million in additional contract capacity by USA for Energy Transformation Services in Moldova, and a new $95 million contract with the United States Navy to support their environmental restoration needs. This broad-based backlog provides us with excellent visibility, through the remainder of fiscal year 2023.

Now, just 10 days ago on January 23, we closed the acquisition of the RPS Group, and we're rapidly moving forward on shared opportunities, collaboration, and actually aligning their systems with ours. And I'm very pleased to welcome everyone at the RPS Group to Tetra Tech.

The RPS Group brings to Tetra Tech over 5,000 staff that are highly aligned with our approach to projects and high-end consulting services in key geographic regions that we've been targeting for future growth for some time.

RPS doubles our staff in the United Kingdom and Australia broadening our services and client relationships in both of these regions. RPS also extends our operations by adding 1,200 employees in Europe, across the countries of Norway, Netherlands and the Republic of Ireland giving us for the first time, a significant presence in that region.

When we actually combine Tetra Tech and the RPS Group, we now have an organization collectively with 27,000 employees, working from 550 offices worldwide, servicing 22,000 clients and we collectively deliver 100,000 projects a year with an annualized revenue of approximately $4.5 billion.

Together, Tetra Tech and RPS, this team is leading the science and driving growth by addressing our clients increasing needs for water, environment and sustainable infrastructure services.

At this point, I'd like to turn the presentation over to our Chief Financial Officer, Steve Burdick, to go through more details of our financial performance in the quarter. Steve?

[Steve Burdick, Chief Financial Officer]

Thank you, Dan. So I'd like to now review the financial results for the first quarter of fiscal 2023. Overall, as Dan mentioned, we had record revenue and earnings and the strong performance from our operations is marked by quarterly revenue of $895 million and net revenue amounting to $737 million, which is a quarterly record for us.

Now when adjusting for the FX change from last fiscal year, revenue was up 7% and net revenue was up 12% over the last year on a constant currency basis. We experienced a strong revenue growth from all the end markets, including US commercial, international, federal government, and our state and local clients.

Our profitability for the first quarter was also very strong. Our adjusted EBITDA came in at $103 million, which was up 16% over last year, and our EBITDA margin increased 90 basis points to 14%. This improvement came from both segments as you heard from Dan about three-quarters of this increase, was driven by our growth in the GSG segment, and an improvement in GSG's operating margin, which was up 240 basis points over last year and about one-quarter of the increase was in operating income coming out of CIG where the margins were up 60 basis points over last year.

Now, our GAAP EPS came in at $2.18. This was an increase of 74% from last year. As noted in our reconciliation summary as provided in the appendix to this presentation, we entered into a hedge for the purpose of locking in the RPS price in US dollars at the time we signed the agreement back in September.

Now for the first quarter of fiscal 2023, we had an FX hedge gain of $68 million that contributed $0.94 to the GAAP EPS.

We entered into this hedge when the British pound was trading at a 30-year load to the US dollar. And ultimately at the time the acquisition closed in late January just 10 days ago, the cumulative effect or the cumulative gain on our FX hedge amounted to about $110 million and this effectively reduced our purchase price by almost 15% and will save over $6 million of interest expense per year going forward. In addition to the hedge gain, we incurred costs related to the RPS acquisition for bridge debt financing fee of about $2.7 million recorded in our net interest and for legal fees of about $3.8 million recorded in operating income.

Now excluding these acquisition gains and losses, our quarterly EPS came in at an all-time record high of $1.34. This was an increase of 13% compared to the adjusted EPS last year.

I also want to point out that our tax rate in the quarter was 25% versus 19% a year ago. And the tax rate differential had an impact on our EPS and that -- if we were at the similar lower tax rate our EPS would have been even higher by another 20%.

Cash flows generated from operations for the first quarter totaled $25 million. Historically, the first quarter is seasonally our lowest period relative to cash generated from operations. Our focus on working capital and cash flows has resulted in our DSO maintaining the leading industry standard of 61 days.

This is a sustainable improvement from prior years and this lower DSO trend continues to reflect the outstanding work that our project managers lead relative to higher-quality projects and highly satisfied clients in our broad portfolio across really all of our end markets and geographies. Our net debt amounts to $82 million and the net debt to EBITDA was at a leverage of 0.2 times with a total cash position of about $164 million.

Now regarding our dividend program, we paid out $12 million in dividends in the first quarter. And I want to announce that our Board of Directors approved a $0.23 dividend to be paid this quarter, and this is our 35th consecutive quarterly dividend and our seventh consecutive year of double-digit year-over-year increases in the dividends paid.

As we presented here today, the continued high-quality operating and financial results with improved EBITDA margins, positive cash flows and lower leverage has provided the opportunity for Tetra Tech to comfortably take on greater leverage through our banking relationships to fund the RPS acquisition, which I will speak to next.

So for those following the presentation, I'd like to present our financial plan for the integration of RPS, which is a significant opportunity for Tetra Tech. And when looking out over the next three years, we expect to; first, increase the actual EBITDA margins of RPS from the lower historical levels to be more in line with Tetra Tech generating margins well over 13%. This will be accomplished in a similar manner as what we had done for our two previous public company acquisitions both Coffey in 2016 and WYG in 2019.

By focusing on high-end differentiated services and revenues, while integrating the business into our ERP platform and our corporate systems for greater cost synergies, we had increased the margins in those businesses from breakeven to the current Tetra Tech double-digit levels.

And secondly, through improved RPS profit margins and cash flows, along with Tetra Tech's strong positive cash flows from operations, we expect to delever our balance sheet to a level to be more in line with our long-term net debt-to-EBITDA goal of one times to two times. And we would expect to have a net debt leverage of about 1.5 times by the end of this year. So as you can tell, I'm very pleased to share these quarterly results with you for the start of our fiscal 2023.

I want to thank you for your support and I will now hand the call over to Jill to discuss just a few of the many business opportunities of bringing Tetra Tech and RPS together.

[Jill Hudkins, President]

Thank you, Steve. RPS is an excellent strategic fit for Tetra Tech, expanding both our global water and renewable energy opportunities. Tetra Tech has a leadership position in water, as demonstrated by our number one water ranking by engineering news record for 19 consecutive years. Tetra Tech is working worldwide to provide our clients with sustainable water supplies and innovative water treatment solutions.

Our rapidly growing digital water practice is advancing water utilities programs by providing remote automation, monitoring and data analytics. The addition of RPS expands Tetra Tech's addressable market by providing us with access to a £10 billion per year UK water market. RPS brings long-term relationships and consulting contracts with all of the major UK water agency clients. These same clients utilize RPS Group's Water net Pro software platform on a subscription basis, a cloud-based decision-making system that provides predictive analytics and visualization for water quality, hydraulics and asset management.

The addition of RPS also advances Tetra Tech's global energy strategy by giving Tetra Tech access to a £15 billion per year offshore wind market in the United Kingdom and Europe, significantly increasing Tetra Tech's renewable energy opportunities. Tetra Tech holds top rankings with engineering news record in renewable energy for hydropower, wind power and solar power. Tetra Tech has long-term relationships with energy utilities, having provided high-end siting and permitting consulting for more than 1000 projects in the US.

For the US offshore wind market, Tetra Tech provided all of the front-end planning and permitting services for the only two operational projects, the Block Island Wind project and the Coastal Virginia Wind project. RPS also brings an impressive resume for offshore wind in the UK and Europe, having worked for over a decade on the development of the [indiscernible] one, two and three wind projects, and providing specialized services in the areas of marine investigation and geophysical analytics.

Together, we are ideally suited to support our clients in the expected 260 gigawatts of offshore wind development in the North Sea, representing a fivefold increase in current wind generation with offices in Ireland, the United Kingdom, Norway and the Netherlands, RPS is well positioned to put Tetra Tech on the map in the North Sea.

And now, I'd like to turn the presentation back to Dan.

[Dan Batrack, Chairman & Chief Executive Officer]

Great. Thank you, very much, Jill. I'd now like to present our guidance for the second quarter and for all of fiscal year 2023. And I'd like to do that in two parts this morning. First, I'll be presenting Tetra Tech's guidance without RPS. And I'll remind the collective group here they've been with us for just 10 days now. And second, I'd like to provide the outlook for the RPS Group's financial contributions for both the second quarter and for all of the fiscal year of 2023 for the amount post-acquisition or post January 23.

I'd like to begin with our guidance as follows for Tetra Tech excluding RPS. For the quarter, for the second quarter of 2023, our net revenue guidance is a range of $685 million to $735 million, with an associated earnings per share of $1.03 to $1.08. For the entire year of fiscal year 2023, we are increasing our net revenue guidance range to a level of $3 billion to $3.15 billion of net revenue, with an associated earnings per share guidance of $4.90 to $5.05.

This guidance for Tetra Tech excluding RPS has the following assumptions. It assumes within this guidance we will take an expense of $0.21 per share, or $15 million for intangible amortizations, we'll have an effective tax rate for the year of 26% for the remainder of the year. We have approximately 54 million diluted shares outstanding and this guidance does exclude any other contributions that would take place after the RPS acquisition.

With respect to the contributions, the financial contributions for RPS for the second quarter, we have estimated that they will contribute approximately $100 million of net revenue to Tetra Tech, with an associated earnings per share of minus $0.10 in the second quarter. For the entire fiscal year of 2023, the eight months that they will be with us in total, we expect that they will contribute approximately $400 million of net revenue and be neutral to our earnings per share on an adjusted basis, excluding transaction and integration costs.

In summary, we had an excellent first quarter and just a fantastic start to fiscal year 2023 setting first quarter records and frankly any quarter records for net revenue income and earnings per share. Our backlog reached another all-time high comprised of services that are aligned with our long-term growth strategy that provide us excellent visibility for the remainder of 2023 and frankly even further into the future.

As we begin the year, we're seeing increased opportunities and demand for our Leading with Science approach and advanced analytics solutions reaffirming our strategy to focus on the high-end services in water, environmental programs and sustainable infrastructure.

And with that, Darryl, I would like to open the call up for questions.

[Operator]

The question-and-answer session will begin now. [Operator Instructions] Our first questions come from the line of Noelle Dilts with Stifel. Please proceed with your question.

[Noelle Dilts, Stifel]

Hi. Thanks everyone. So I was hoping that you could just expand a bit on your expectations around RPS margins for fiscal 2023. I think when RPS had -- before the acquisition, had been talking about kind of getting to a double-digit EBITDA margin in the near term. So could you just, expand upon sort of how you're thinking about the margin profile this year, and how the cost savings that you've laid out rollout over the next basically 2.5 years? Thanks.

[Dan Batrack, Chairman & Chief Executive Officer]

Absolutely, Noelle. Thanks for the question. Steve, actually put together a slide that was included in his prepared remarks, that graphically depict our expanding margin expectations for the RPS Group. Now in 2022, which has been completed let's call that the trailing 12 months, RPS Group was around 4%, just slightly over 4%. We expect that under Tetra Tech that number will double and we expect as an average for the year, that that will increase to approximately 8%. In fact, we'll be exiting fiscal year 2023, at a run rate closer to 10%.

But for the average, that they'll contribute for 2023, it would be approximately 8% for the year, with it beginning at approximately 4% now, and expanding to a run rate at about 10% at the end of the year. We expect in 2024, that number to move into a double-digit level approximately 11% and that level it will enter at about 11x at about 12 with an annual average right there in the middle, at about 11 and that would be for 2024. And then finally, in the following 12 months, we expect that to be up at Tetra Tech level, which would be a 13% plus.

Now, in one respect, I would say that 2024 sounds like a long way away. But since, we're on the US federal government calendar, that's less than eight months away. So, it's actually quite close. With respect to savings, I did make a comment on the adjustments with respect to our forecast for contributions from RPS to Tetra Tech.

We do expect that on a cost synergies basis, moving to common platforms and aligning our systems, we will see -- once fully implemented, we will have approximately a $25 million contribution from reduced cost or it will contribute to their EBITDA. That is embedded in helping assist to get to the margins that I had just indicated.

We expect that it will cost us about 10 -- I'm sorry, it will cost us about $20 million, in order to achieve the $25 million in savings per year. We expect we'll get about half of that cost synergies this year, in fiscal year 2023. So of the $25 million we'd expect, we get about $10 million, a year savings here in this current fiscal year. The cost for that will be about $15 million.

So of our total $20 million that we'll spend to achieve the $25 million, we'll incur about half of that this fiscal year. That will leave about $5 million for fiscal year 2024. We expect the annual yield to be up to about $20 million, a year for 2024, and then beyond that 25 on an ongoing and future basis. I know I ran through those numbers, pretty fast. So, there's some questions on that I'd be happy to get into those details or have Steve, provide some of the underlying support.

[Noelle Dilts, Stifel]

Sure. I think, I commit – so, I think I guess, just while we're on the RPS topic. I know that sales synergies have been discussed, as a key reason for the acquisition. Could you expand upon how you're thinking about some of those opportunities, and really the growth potential of the combined sort of Tetra Tech-RPS entity again as you look out over the next couple of years?

[Dan Batrack, Chairman & Chief Executive Officer]

I'm really excited about that. I know that our financial folks and certainly I take great satisfaction on the accretion. I know we've talked about -- expect the RPS accretion to Tetra Tech once they've joined us for a year and we've actually had them integrated to be in the mid- to upper teens on a financial basis. I still believe that's easily achievable. In fact we look to perhaps do even better than that. But what actually is the most exciting is the revenue synergies.

And I think that Tetra Tech combined with RPS gives us new geography and new capability that -- and I won't use these terms very often is unmatched in permitting for some of the most innovative renewable energy programs out around the world. And offshore wind is of course one of the very biggest. I know Jill spoke a bit to it. But RPS would not have the ability to have access to the US markets that Tetra Tech brings and Tetra Tech would not have any meaningful participation in the largest new growth areas for offshore wind that go through the North Sea and other areas. So, I do think this is an example that's one plus one is not slightly more. I think it's one plus one is four or five.

The other item we've been very anxious to participate we think we can bring enormous value to the UK water markets. Tetra Tech has been doing water quality programs. We've been doing impacts of agriculture and livestock loading into water quality streams with respect to things like total maximum daily loads for chemical loading. This is the new priority for the AMP programs or the asset management programs for the water utilities in the United Kingdom and that's what Tetra Tech's been doing for the US EPA and the US local state and governments here for the past 30 to 40 years and it's just new advent as a priority in the UK.

So, I think what we have plus the position that RPS has a holding framework or master service agreement contracts with every one of the major water utilities in the UK is another area where it's not just plus one is slightly more than two I think it's a big move.

And while RPS currently is number five or number six ranking as far as revenues for the UK water utilities, I think with the advent of Tetra Tech we're going to move up that rank pretty fast by providing much better value that the water utilities have never seen before.

And they can do it on the back of the investments that was made by the US government measured in the hundreds of millions of dollars if not billions. They don't have to invest that. They can get that by Tetra Tech bringing that technology capability to the UK and actually building on the backs of the investments done here in the United States.

[Noelle Dilts, Stifel]

Great. Thanks very much.

[Operator]

Thank you. Our next questions come from the line of Andy Wittmann with Baird. Please proceed with your question.

[Andy Wittmann, Baird]

Great. Thanks for taking my questions everyone. Dan I was just hoping maybe to just get a good sense of the quarter and how it relates to the guidance here. So, I guess I asked the question this way.

You mentioned the GSG segment kind of had some items that artificially -- I don't artificially certainly earned them but the margins were a little bit higher than you expected and shouldn't be viewed as a continuing benefit. In fact you said 15% is kind of more like what the underlying performance was.

So like if you just do the difference of that margin difference -- it's probably about $0.10 which means you beat the quarter and beat your guidance but not as much. It looks like basically most of the guidance raise not all of it but the majority of the guidance raise is due to that GSG segment margin performance.

So, I guess the first question is, is that the right way to think about your guidance and the implication is that the balance of the year outlook is still good and supported, but maybe it's not terribly changed. Is that the right way of thinking about it?

[Dan Batrack, Chairman & Chief Executive Officer]

Yeah. I think that is primarily the right way to think about it. We had a great first quarter. The reason I made the comment that the extraordinary contributions and of course, I would say that we had -- we mobilized an additional 1,500 staff during the months of October through December to respond to Hurricane Ian, all across Florida.

We were really busy. We mobilized staff from across the rest of our operations to go down there and to accelerate the response, to minimize the impacts, to the residents of Florida in the surrounding area. But I do consider that, an extraordinary with climate change and the impact of storms, I'm hesitant to say one-time event, because it's certainly not really become that.

But the 17% if you model that out, it would have our guidance going up way up. Now, we did flow through every bit of the beat in the quarter for our annual guidance and more. So we do expect things will be a little bit stronger. But we came into the year with actually a very high forecast for EPS.

And we had actually embedded in our forecast for 2023 another 50 basis points increase in our margin across the company. And so to actually maintain that and increase it a bit, while actually absorbing and flowing through all of the beat that we had in Q1 I would say that, yes when you say, does it leave intact primarily the guidance we had coming into the year? I would say, yes, although, we did increase it even more than the beat. So we do have optimism coming in.

And of course, in order to -- with only 10 days with RPS with us was really -- we struggled with, how can we communicate? What they're going to contribute, while trying to have perfect insight after 10 days. And that's why we really presented this in two components. What is the base company doing, which you just highlighted we flow through all, the beat and more a little bit more.

So yes, it remains intact plus -- and then, I think as we go through the year with RPS, we'll look to actually begin merging that into Tetra Tech, as we integrate the company. And you're going to see one collective number. And it doesn't take much to add these together to do a calculation on your and our collective parts to see the top line is growing well over 20% with these individuals.

And I'll be really excited to present what is going to contribute to the bottom-line both on valuable cost synergies and revenue. But yes, I think your characterization of our maintaining and improving our outlook through the year even with the beat is accurate Andy.

[Andy Wittmann, Baird]

Okay. And then, I guess, the follow-on question to that is -- obviously only 10 days with RPS here, but going forward can you just talk about how you're going to talk about EPS guidance there's going to be an intangible amortization hit which you don't know yet obviously.

And so you gave us I think a very realistic way of looking at it with this kind of two pieces. But going forward do you think that -- is 2023 going to have like an adjustment for some of this intangible amortization?

And then maybe as you go to the future 2024 something that you kind of get back to just closing it more like you've done historically which is really founded in GAAP principles, or how are you talking and thinking about that internally?

[Dan Batrack, Chairman & Chief Executive Officer]

I think that's a great question. That's a great question. That -- for those that have followed Tetra Tech's guidance you would know that we're on a GAAP. In fact, I think we're the only company not just in our industry but any industry that actually does adjustments and moves our actual performance down.

And you can see that we adjusted from over $2 a share of earnings per share down to our $1.34. You would have seen each of the quarters last year. We took any type of extraordinary contribution and adjusted our EPS down. So I don't know who does that other than Tetra Tech.

And we do present the GAAP and we continue -- and we look to revert to that once we've actually incorporated RPS and understand what the one-time transaction, which we actually know those costs with the integration cost and the intangible amortization. I expect those will be on an adjusted basis.

We'll be quite transparent as to what those are. But as we move into 2024, I expect us to be returning to where we've historically been. In fact even this quarter where we've been, which is the cleanest, most direct reporting of our results, which are on a GAAP basis. And if there are extraordinary contributions we've even taken those out to reflect our increases that are well into the double digits.

So yes I'm not looking to change Tetra Tech's reporting off into the future. But there are so many one-time items associated with RPS joining us. It would only be appropriate to provide a clear accurate understanding of their contributions by adjusting for those because they are one-time and in the case of intangible amortization, we don't even know that number yet. So we'll put that into place this next quarter. We'll probably have adjustments through 2023 and then we'll return at appropriate timing to GAAP reporting for the company.

[Andy Wittmann, Baird]

Okay. That all make a lot of sense. Thank you for your time and prospectus.

[Dan Batrack, Chairman & Chief Executive Officer]

Great. Thank you very much, Andy.

[Operator]

Thank you. Our next questions come from the line of Alex Dwyer with KeyBanc. Please proceed with your question.

[Alex Dwyer, KeyBanc]

Hi guys. Can you talk about the IIJA? It sounds like the expectation is still for a minimal contribution later this year? Has anything changed here since the last update maybe in terms of customers moving forward with projects or more funding coming through the pipeline? I'm just trying to get a sense of what's currently baked into the guidance could ultimately prove conservative this year?

[Dan Batrack, Chairman & Chief Executive Officer]

Well, a good question. It's probably one we get quite frequently. It's ever since both the IIJAs passed into law I would say when the CHIPS Act and even the Inflation Reduction Act and then some combination of the special legislation this past we get different varying comments. We do believe it will have a contribution, primarily late in the year. We have it been quite de minimis overall. The growth rates that we've had in our state and local, which we expect one area to be contributed to the funding. We've seen our clients begin to get some of the funds or grants provided to them but they haven't necessarily flowed at any material level to us yet.

I expect in late Q2 but really Q3 and Q4 these projects to start. It's mostly going to be on the very upfront planning, the initial outline even conceptual design. And so I expect many projects to start in the second half of fiscal year 2023. But what's exciting for us about it is not the financial contribution in 2023, but it's when you start a program they start at a small level and they begin to build up like a bell curve. And these are projects that start with small conceptual tasks and assignments. They move into permitting the detailed design. And so they'll build and really contribute over many years.

So these programs that will start in the second half of this year are going to build for multiple years and they'll contribute for three to five years or more. And then, of course, owners engineer and oversight during implementation by the constructors. So it's a de minimis contribution during 2023. Really had no contribution in our first quarter and is not included in any material way in the second quarter. You'll see it begin to build in the second half. And I've not seen anything that would cause it to be delayed or pushed out to the right. And we're now seeing what's appropriate the funds go to our clients, which will then trigger their ability to procure and you'll begin to see it in backlog.

But I'd also say not only did it not contribute to the revenue in the quarter, I do want to make the note IIJA and the other funding sources did not contribute to our backlog growth in the first quarter. That was excluding anything that I expect – and really will come later in the year for backlog. So the sequence, of course, is -- it goes into contract capacity then it goes to backlog which we report in detail then converts to revenue. So we're still a few quarters out from seeing that contribute to the revenue side.

[Alex Dwyer, KeyBanc]

Got it. And second question you guys raised the margin target ranges for both of the segments last quarter. And this quarter was interesting with the GSG margin coming in well above the high end of the range even when you back out those three items you called out in the prepared remarks. I was just wondering, if there was the latest message on the timing of CIG margins potentially catching up with GSG margins. If this is still the case or what the time line could be?

[Dan Batrack, Chairman & Chief Executive Officer]

That's a great question. It's a great question. Every time I speak with our CIG leads and executives, and they say, they're going to close the gap GSG widens the gap by additional performance like you saw this last quarter. I will say that we expect that GSG as an overall range for the year to be between an EBITDA margin between 13.5% and 14.5%.

GSG thought they were beginning to close that gap by being 13.1% in the first quarter. I keep saying, I expect that to close and then GSG puts in a 17% margin and what they would say to me and have said to me is we can do better. So, I guess, what I'll say at this time is I expect both the GSG and CIG margins to expand. We included a 50 basis point increase in 2023 over 2022. And I do think GSG was a bit of an outlier because of the disaster and a few other items. And I do still think CIG will catch and surpass GSG.

The only thing I can tell you is, is it going to be in one of the quarters this year. But if they miss it it's not because CIG has underperformed it's because GSG has outperformed. So for our investors and shareholders and analysts who track this, if CIG doesn't catch or surpass GSG, it's good for our performance because that means we're going to be over the top of any of our estimates as you saw this last quarter.

Thank you. Our next questions come from the line of Tate Sullivan with Maxim Group. Please proceed with your question.

[Tate Sullivan, Maxim Group]

Hello. Thank you and good morning. Again you mentioned renewable energy great growth in US commercial and used the term I haven't heard before renewable energy services being a fast-growing business. Is that is the majority of that already the offshore wind projects that you work on before adding RPS?

[Dan Batrack, Chairman & Chief Executive Officer]

That has been the fastest-growing area. I will say onshore wind has still continued to be strong. Solar has actually been strong. Of course, hydro is really the largest single component right now between both what we're doing in Canada and the US. But I would say that as of well pre-RPS -- I don't want to say as of today. As of 10 days ago and earlier, it would have been almost exclusively what we're doing in Canada and the US.

But now with RPS joining us we think the opportunities will actually be substantially greater and add the new renewable energy work in Australia and UK, Europe, which I commented on. But the areas that have been -- that helped grow and drive our commercial 22% growth year-over-year, renewable energies was a big part and permitting for offshore wind was a big aspect of that.

And one thing, I don't want to understate what Jill said, the only two operationally productive that are actually producing energy offshore wind projects in all of the United States, all of the permitting and upfront study work and support was done by Tetra Tech and in fact most of the offshore leases that came from the New York bite, which was the big lease auctions that were completed here over the past many months, we're supporting most of those.

And right, when we feel that things are great here in the US like having the only two operational programs that we did and having most of the new offshore leases that we're supporting, what are we told by RPS, that's small and puny, and I hope you guys can pick it up, because we did the Hornsea 1, 2 and 3 which is the world's largest offshore wind generation facilities and we're beginning others that are actually larger than it. So I think when you take Tetra Tech programs and RPS', it really looks very favorable for us going into this year and on into future.

[Tate Sullivan, Maxim Group]

And bringing what you have done in offshore wind to RPS is it similar capabilities, or is there some work that you can – so should this be cross-sell the RPS and offshore wind and the opportunity in the UK?

[Dan Batrack, Chairman & Chief Executive Officer]

We can – one thing that's interesting is the work that RPS has been doing to support the offshore wind is different than what we've been doing. Now, they're both under the buoy's or under the general topic of permitting or offshore studies. But RPS brings new technologies that we've just not seen or utilized here in the United States. So an example would be they have offshore automated autonomous buoys. And these are very large buoys. They're almost like small vessels and they have LiDAR systems on them. They have Radar systems. They have self regenerating power supplies through solar panels.

They measure all of the different attributes necessary for modeling in case of a discharge of oils or some aspect of environmental impact from the offshore wind or the vessels that are actually servicing them. So if you have a vessel out there and there's an oil spill, you can do real-time monitoring for oil spill, trajectories state, transport all the rest of it real-time on-site with these buoys. And we haven't used those here in the United States.

On the other hand, the work that we have here in the US with the offshore very high resolution green biology divers impacts to Benthic studies, which are underground critters in the water. Fisheries, avian flyways, the very high radar systems that we have to monitor all types of avian species, birds others we have here in the US. We have a small fleet of offshore high-resolution surveys bathymetric surveys, hydro survey, sub-bottom profiling and real-time evaluation of marine mammals, we can bring to them. So they'll bring to us technologies we've never seen in the US and we'll bring to them technologies that haven't yet been used in Europe or other locations.

So I think it really is very complementary and synergistic. So – that's why again, I love the financial model that will come out with mid to high-teens accretion no doubt that's fantastic. But on the revenue side, what we can bring to the industry is just really exciting to us.

[Tate Sullivan, Maxim Group]

And then I mean one thing on RPS, I was – and maybe it depends on transitioning it to the GAAP accounting the higher subcontracting costs to get from revenue to net revenue. And then to bring up RPS' margins does that imply some divestitures perhaps – do they do some lower-margin construction management work – or is that –?

[Dan Batrack, Chairman & Chief Executive Officer]

Yeah. There – well, the gross to net is actually smaller than Tetra Tech. So they actually have less of a difference from gross to net. So on a full annualized basis, a 12-month basis, there are about $700 million on gross revenue or total revenue, and we expect on an annualized or 12-month basis to be around $600 million on net revenue. So that about 15% difference between gross and net is actually less than that at Tetra Tech. Tetra Tech, here we do more government work than they do and we have more requirements for using small disadvantaged participation on execution of federal work. And so we naturally have contractual obligations to meet the subcontracting requirements.

As far as, do they have some work that is lower margin, yes. We're not necessarily see divestiture. But as we had implemented in both Coffey and WYG, we are going to change the model and move it decidively to one direction which is more high-end, which is reflected with less competition, higher margin and technically differentiated services that are just not offered in the marketplace or have a much different competitive landscape in the marketplace. So the efforts will be not to be bigger, but our absolute focus is to be better with RPS. And where that can be reflected. That is going to be reflected in margin.

[Tate Sullivan, Maxim Group]

Thank you, Dan.

[Dan Batrack, Chairman & Chief Executive Officer]

Thanks, Tate.

[Operator]

Thank you. Our next questions come from the line of Michael Dudas with Vertical Research. Please proceed with your question.

[Michael Dudas, Vertical Research]

Thank you. Good morning, Dan and Jill.

[Dan Batrack, Chairman & Chief Executive Officer]

Hi, Michael.

[Jill Hudkins, President]

Hi, Michael.

[Michael Dudas, Vertical Research]

Okay. So yeah, moving -- continuing on the thoughts on RPS. I know it's only been 10 days and such, but maybe you could share a little bit about your expectations relative to managing the new employees retention expectations? Are there any significant senior people that need around the -- or joining the team? And relative to that and the margin question you just touched on before, have these margins in more Tetra Tech expertise and value proposition adds to the -- through the contract base of RPS, or are there things RPS can do better to extract those better margins amongst their -- especially their government clients?

[Dan Batrack, Chairman & Chief Executive Officer]

Well, so two questions there. One retention, the second is increasing the margins or project execution. With respect to retention, it is new. We do have retention programs here in Tetra Tech. We have equity positions that we will provide access to Tetra Tech stock, as we do with Tetra Tech staff that actually is a component of retention. We actually want every employee to be an owner of the company and have same alignment as our outside shareholders. So we are putting that in place. We certainly have selected a retention of stock awards that vest over multi-years for select areas across the top to make sure that they own a piece of the rock and they're part of the organization and that vests over multi-years as does for every Tetra Tech employee and the existing management of Tetra Tech here.

I will say RPS's turnover currently or I shouldn't say currently, prior to our acquisition is higher than Tetra Tech, quite a bit higher. And Tetra Tech's overall turnover rate is right around 10% slightly below that. But the turnover rate of Tetra Tech when you've been here more than five years at the company is in the order of sort of circa 1% is quite low. And what I'm looking to achieve is actually to put that type of career stickiness with the people at RPS. This is not a next step in their career. This is the next landing spot where they will continue their career all the way through retirement for those that want to be high-end technical engineers and scientists. I expect they have a home here forever and that they'll help make Tetra Tech better than we were before they joined us, and it provides our clients extraordinary levels of institutional knowledge consistency. Tetra Tech is not going anywhere.

The next recession is not impacting our business. And in fact if you look at 2008, we grew through that. If you look at the pandemic we were up through that. And so the tougher things get the better home this is for those employees.

Now with respect to can they run better? I do think that they have been hampered and they have been restricted with respect to a lack of a single ERP system in their back office. I think that the ability for their project management and technical staff to have real-time understanding of where they are decisions-making to be made immediately with respect to immediate access of percent complete accessing of knowledge systems across the entire organization is substantially higher at Tetra Tech.

We've just been -- we're -- I don't know one to two decades ahead of where RPS is on that journey and we're going to move what was another five or 10-year journey for them. We're going to move that into 12 to 24-month period, and they'll be on our systems. And so I think that will help provide new solutions for their clients and which then will result into better performance by ourselves, and better delivery and value propositions for all of our collective clients and the 100,000 projects. So with respect to efficiency and how are we going to drive the higher margins not just on cost, it's going to be giving them the tools that they can even do their existing jobs better than what they had done prior to joining Tetra Tech.

[Michael Dudas, Vertical Research]

Excellent, Dan. Thank you.

[Dan Batrack, Chairman & Chief Executive Officer]

Thank you, Michael.

[Operator]

Thank you. This will conclude the Q&A session. I will now turn the conference back over to Dan Batrack to conclude.

[Dan Batrack, Chairman & Chief Executive Officer]

Thank you very much Darryl, and thank every one of you for being on this call. Thank you very much for your patience with us, as we look to have more clarity with respect to the very specific contributions on both revenue and earnings and really the outcome of the revenue synergies that we have with more projects for our end clients.

I know that, again, gives us probably too many times during this call, but the first 10 days with us have actually been exceptional. I had the great pleasure to be in the UK last Monday when we closed and had a chance to spend the entire week with many of their operations across the UK, Norway, Netherlands, and I left more excited than I went even going over there.

I think it's going to be a great contribution. I'm going to have the great opportunity to do the same across our Australian and Asian markets. And it's not just me going in a ceremonial visit, it's actually going on the front line with our operations staff that are initiating the collaboration for new project wins. And I will say in the first day, we've already had wins together that we otherwise wouldn't have had.

So I hope you can tell from today's presentation, I'm really looking forward to sharing with you the more details and progress that we're making, and that will be as soon as this next quarter only 90 days away. And I hope you have a great rest of the week. And I look forward to talking to you on next quarter's call. Thank you.
