Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Thanks, Todd. Good morning, everyone, and thank you for joining us. The Northrop Grumman team delivered another year of strong performance in 2022, positioning our company for the coming year and beyond. A growing global demand environment and the team's success in capitalizing on competitive opportunities drove exceptional bookings. Top line growth accelerated throughout the year, driven in part by improving labor trends. I'll note that we set our sales and EPS guidance ranges at the beginning of 2022 and even in a dynamic macroenvironment. We navigated the challenges to deliver at or above the high end of those ranges and in importantly to deliver capability for our customers. This performance highlights our solid operating execution, our ability to win new business and the alignment of Northrop Grumman's portfolio to our customers' priorities.

We enter 2023 with a backlog of more than 2 times our annual sales. This strong backlog along with increasing demand and rising global defense budget supports our expectation for continued growth. Given this and supported by robust headcount growth, we have increased our 2023 sales guidance range from our October outlook. We are projecting solid segment margin performance. It takes into consideration inflationary pressures and supply chain disruption, consistent with the expectations we outlined on the October call. And we expect a greater than 20% compound annual growth in our multiyear cash flow outlook that supports continued investments in the business and significant returns of capital to shareholders.

Before providing more details on our outlook, I'm going to highlight a few notable achievements from the previous year that underscore the tenets of our long-term strategy and illustrate our positioning for the future. In 2022, the James Webb Space Telescope proved its status as the world's most powerful Space Telescope and an engineering marvel. It achieved full operational status, shared first images in July and continues to discover and inspire with this incredible insights into distant galaxies. This project is just one example of the technology innovation and leadership our team brings to our customers, and it has provided an excellent platform for attracting talent to our industry and our company.

In 2022, we continued to win new competitive awards across the company, achieving a book-to-bill ratio of 1.07. Two notable new awards are the Space Development Agency's Tracking and Transport Layers. As our customers look to expand the resilient National Security Space capabilities, these programs leverage our advanced space solution for low earth orbit and showcase our ability to compete and win programs across a range of mission.

We also completed over 40 successful launch in space missions in the year, exemplifying our end-to-end capabilities in the space market and our ability to perform at scale. Further, our solid rocket boosters helps propel NASA's Space Launch System as part of the Artemis I mission with the largest human-rated solid rocket boosters ever built. We also received a $2 billion award for GEM63 solid rocket boosters in support of Amazon's project Kuiper. Together, SLS and Kuiper validate the robust investments that we've made in solid rocket motor capabilities.

We also delivered advanced architectures that integrate sensors to provide unprecedented situational awareness for our customers. One example is our IBCS solution. After successful testing in the fourth quarter, IBCS is poised to transition from LRIP to full-rate production in 2023. IBCS integrate systems that weren't designed to work together, creating a seamless air and missile defense network and allowing customers to better utilize their defense assets. This capability is needed more than ever to address advanced threats and it's one where we've seen a significant increase in interest across our global customer base with 10 additional countries expressing interest in obtaining the system.

We continue to keep our focus on innovating and leveraging our strong position in advanced technology. This includes the development of a new radar for the F-35. This radar is capable of defeating current and projected adversarial air and surface threats and it's compatible with variance of the F-35 aircraft.

And we capped off a strong year with the historic unveiling of the B-21 Raider. The B-21 is a multi-functional platform with unmatched range, stealth and survivability, and it'll be the backbone of future US Air power for decades to come. We continue to perform well on the program and remain on-track for first flight later this year. As the program transitions into low-rate initial production. We are working to address macroeconomic conditions, especially related to inflation and their impact on material, suppliers and labor.

Importantly, I want to highlight that our B-21 unit cost projections remain below the government's independent cost estimate. The program has strong support from the US Air Force, Congress and our suppliers. And in the words of Secretary Austin from last month's rollout, this aircraft is proof of the department's commitment to building advanced capabilities that will fortify America's ability to deter aggression today and in the future.

Our 2022 achievements underscore the breadth of our portfolio across a wide range of domains and technologies and the strong performance of the entire Northrop Grumman team. As we look forward, defense budgets are on the rise and we see our global customers continuing to seek proven solutions to address rapidly evolving and increasingly sophisticated threats. We are meeting their urgent needs in areas such as air and missile defense solutions, medium and large caliber ammunitions and armaments, advanced radar capabilities and global surveillance, to name just a few. And we are partnering to expand our opportunity set and positioning our international business for future growth. We clearly saw increased demand in 2022 and we continue to expect to grow our international business over the next several years.

In the US, we are encouraged by the continued strong support for national security, including overwhelming bipartisan support for a 10% spending increase in the fiscal year 2023 defense budget that was passed in December. Our portfolio and the capabilities we offer are well-supported by the administration and Congress. Growing security challenges will test our resolve in ways not seen for a generation, and we are confident this administration and the new Congress will find ways to work together to meet them. We expect the President's fiscal year 2024 budget request to support robust funding for the highest priority capabilities outlined in the National Defense Strategy.

And our strategy has positioned us well. We're clearly maintaining our technology leadership and growing our portfolio of offering, which is aligned to customer priorities. Another key element of our long-term strategy is keeping a laser focus on performance and driving cost efficiencies throughout the business. The current macroeconomic environment reinforces the importance of doing so. An example of our effort is the implementation of digital solutions across the company. Beyond the benefit of transforming how we design, test and manufacture in the next generation of systems, our digital initiatives are streamlining business functions and increasing productivity.

We are also optimizing our facilities and consolidating our real estate footprint. Every day, we seek new and innovative ways to drive performance and increase efficiency, while remaining agile and meeting our customers' expectations. Our capital deployment strategy supports our business strategy. We are investing to not only drive efficiencies, but also to allow our customers to stay ahead of the threat environment. In 2022, we invested over 7% of revenue in R&D and capital expenditures to provide the capability and capacity needed to address the threats of today and tomorrow. We also continued to return cash to shareholders. Last year, we increased our dividend by 10%, which was the 19th consecutive increase. And during the year, we delivered over $1 billion to shareholders through the dividends and returned another $1.5 billion through share repurchases.

So looking forward to 2023, we are well-positioned for continued growth and our revenue outlook has improved from the high $37 billion range. We shared in October. We now expect sales to be in the range of $38 billion to $38.4 billion, representing about 4.5% growth at the midpoint. Margins are expected to remain solid in the 11.3% to 11.5% range. We are projecting strong free cash flow growth that supports our capital deployment strategy. And we expect to return more than a 100% of free cash flow to shareholders again in 2023. Our backlog, strong recent global demand growth and our ability to deliver products that address an increasingly complex security environment give us confidence in our outlook.

So with that, I'll hand it over to Dave to cover the details of our financial results and more on guidance.

Dave Keffer
Corporate Vice President and Chief Financial Officer at Northrop Grumman

Okay. Thanks, Kathy, and good morning, everyone. I also want to thank our team for another year of strong performance in 2022. We won several new franchise programs, delivered industry-leading top line growth and bolstered our talented workforce with the addition of over 6,000 net employees during the year. I'll spend a few minutes on our fourth quarter and 2022 results and then discuss our future expectations in more detail, including our long-term cash flow projections.

We ended the year with nearly $79 billion in backlog, reflecting strong demand for our products and capabilities. We continue to convert our backlog into revenue at an accelerating rate, with fourth quarter sales growth of 16%. This was enabled by our ability to continue strong hiring in Q4, as well as a higher volume of material receipts based on the timing of program demand. The team did an outstanding job of working with our supply chain to secure program material, and for the full year, our sales grew to $36.6 billion, representing organic growth of 3% and exceeding our prior expectations.

Our operating performance and margins remained solid, despite the continued pressures of the macroeconomic environment. Our segment operating margin rate was slightly below our expectations at 11.3% in Q4 and 11.6% for the full year, due in part to the impacts of inflation, which resulted in a lower level of net earnings adjustments, but margin dollar volume was very strong given the top line outperformance. A positive EAC adjustment in the quarter was on B-21, where we recognized a $66 million pickup on the EMD phase of the program, reflecting our latest assumptions regarding future incentives in that phase.

Continuing with our Q4 results. Our transaction adjusted earnings per share was $7.50, a 25% increase over the same period in 2021. Higher EPS were driven by robust growth in our segment top and bottom lines, as well as a lower effective tax rate. The lower Q4 tax rate was driven by the recognition of an $86 million benefit from the resolutions of a Legacy Orbital ATK tax return, which we previewed in our guidance last quarter. And corporate unallocated costs were also below our expectations due to lower state taxes as a result of the R&D tax amortization law not being deferred. For the full year, our transaction adjusted earnings per share were $25.54, well ahead of our guidance range.

Now turning to cash, we had an extremely strong fourth quarter consistent with our historical pattern. For the year, we generated $2.9 billion of operating cash flow and $1.6 billion of transaction adjusted free cash flow, in line with our expectations. This was inclusive of a full year of cash taxes associated with the R&D tax amortization law, as well as our final payment of deferred payroll taxes from the CARES Act legislation.

Moving to our pension plans. Slide 7 in our earnings deck includes our latest assumptions. After three consecutive years of double-digit asset returns, our plans declined by roughly 15% in 2022, in line with market trends. Our FAS discount rate increased roughly 250 basis points to 5.54%, which was the driver of the mark-to-market pension benefit of $1.2 billion reflected in our GAAP results. These factors are also reflected in our latest pension estimates for 2023 to 2025. As we previewed last quarter and updated in our slides today, we're projecting a decline in our non-cash net FAS pension income and an increase in our estimated cash recoveries. In total, our pension plans remain strong. As a result of the higher discount rate our funded status has improved to nearly 100% and we continue to project minimal cash pension contributions over the next several years.

Now turning to 2023 guidance, our revenue expectations have increase from our prior estimates with the midpoint representing nearly 4.5% growth on top of the strong level in 2022. We expect Space Systems to remain our fastest growing business. Sales are projected in the mid $13 billion range, up over $1 billion from 2022 levels, with GBSD and NGI contributing nearly half of the growth and the rest coming from our broad Space portfolio. Mission Systems sales are expected in the high $10 billion range, up mid-single digits, driven by restricted programs in our Networked Information Solutions business. And we continue to expect flattish sales at both Aeronautics and Defense Systems. While programs like B-21 and IBCS continued to grow, headwinds remain on legacy platforms as systems are retired. We expect Aeronautics and Defense Systems to return to growth in 2024.

And similar to our cadence in 2022, we expect first quarter sales of approximately 24% of our full year estimate, with sales ramping again throughout the year. With respect to margins, we expect our 2023 segment operating margin rate to be down roughly 20 basis points from 2022 levels. Challenging macroeconomic conditions, including extended lead times in the supply chain and high levels of inflation continue to put temporal pressure on margins. And while higher CAS recoveries provided a modest benefit to our cash flow in the coming years, they create pressure in our overhead rates and EACs. Similar in nature to what we experienced in the first quarter of 2021 when we recognized a favorable impact from lower projected cash cost, this could lead to an unfavorable margin impact when we update our rates this quarter. We notionally expect this to have a 10 basis point to 20 basis point impact on the full year.

In regards to the B-21 program, we expect the 2023 Contract Award for the first five LRIP lots, with the LRIP phase scheduled to run through approximately at the end of the decade. We are continuing to work with our customer to address macroeconomic risks and enhance efficiencies in the program. As we've described in our 10-K, we do not believe that a loss on the LRIP phase is probable, and therefore, no such loss is reflected in our results or guidance.

Now turning to our future outlook. We expect our 2023 earnings per share to range between $21.85 and $22.45 based on approximately 153 million weighted shares outstanding. This includes $450 million of net pension income, which represents a $4.30 per share headwind compared to 2022. Partially offsetting this non-operational headwind is strong growth in segment performance and the lower share count, which adds roughly $0.90 of additional earnings per share. And lower purchased intangible amortization largely offsets the higher tax rate.

Moving to cash, we expect 2023 adjusted free cash flow between $1.85 billion and $2.15 billion, consistent with our prior outlook as adjusted for current R&D tax law. Although we expect discussions to continue on Capitol Hill, our guidance and multiyear outlook are now based on current tax law for all years and do not include any refunds for R&D taxes paid in 2022.

Capital expenditures are expected to remain elevated at $1.65 million to $1.7 billion in 2023 and a similar level in 2024 before moderating in 2025 and beyond. This is driven by investments to support several large new business wins from 2022. Our guidance assumes we will not have an extended CR, a breach of the debt ceiling or a prolonged government shutdown, as this is our current expectation.

Slide 12 in our earnings deck provides our long term cash outlook, which is predicated on continued top line growth in our business generating strong and gradually expanding operating margins and converting those margins into cash. R&D related cash tax payments should decline by about 20% per year. As I described, capex is expected to remain near 4.5% of sales in 2023 and 2024 before starting to decline in 2025. After investing in our business, we continue to expect to return more than 100% of our free cash flow to shareholders in 2023 in the form of dividends and share repurchases. And we plan to be in the market for new debt issuance soon to support our capital deployment plans, including the refinancing of near-term maturities.

In summary, 2022 was another successful year for Northrop Grumman and we continue to deliver value for our customers, employees and shareholders. And with that, we're ready to take your questions.

Thank you. [Operator Instructions] We ask that you limit yourselves to one question with one follow up. One moment for our first question. Our first question comes from the line of Kristine Liwag, your line is now open, with Morgan Stanley.

Kristine Liwag
Analyst at Morgan Stanley

Good morning, everyone.

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Good morning.

Kristine Liwag
Analyst at Morgan Stanley

Good morning, Kathy. Kathy, you mentioned in your prepared remarks that the B-21 cost estimates are below the government estimates, but you know, as Dave mentioned, there are macro and inflation cost pressures. I mean this comments really stood out to me since in the past decade, we've seen many large defense development programs exceed costs and not just by smidge but meaningfully. Can you provide more color on what the Northrop team is doing to manage this risk and how we should think about the LRIPs through the end of the decade and what are the puts and takes in terms of potential risks?

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Yes, so as we noted, we are performing exceptionally well on the B-21 program and we have continued government support for the quantities of at least a 100 bps that are represented in the program of record. But given that this contract was initially awarded in 2015, the recent and really unprecedented macroeconomic impacts of inflation, labor, supply chain disruption have affected the cost estimates to perform on the LRIP phase of the program.

And importantly, we noted our projected cost per unit are still below the government cost estimates upon which the funding profile is based and that's important because it supports the overall buy plan of the US government. And you know just to as a reminder on timing, the government hasn't yet exercised any of the LRIP option. So like we do on any priced options, we continue to look at what the future may hold, and reflect that in our estimates to complete, but those are indeed estimates of costs and future performance.

So while as we noted in the K, we don't currently consider a loss on LRIP to be probable. If it were ultimately to occur, it would spread over all five lots of the program, and particularly, that's important and related to any cash flow impact. So as we look at 2023, we do not see that is material in our cash flow outlook and even as we put together our three year cash flow outlook, we wouldn't see that as being material. So hopefully that gives you a sense of what is contributing to the B-21 cost estimates, inflation, clearly is the primary driver there, as we think about what's changed recently in our estimates, and we are working to mitigate those impacts as you say, and we have some time as we move forward and get into production to continue to do that.

Kristine Liwag
Analyst at Morgan Stanley

Thank you for all the color.

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Norma, we're ready for our next question.

Operator

Our next question comes from Ronald Epstein with Bank of America. Your line is now open.

Ronald Epstein
Analyst at Bank of America

Yeah, thanks. Maybe my first question is on -- on Space. You know, the performance there is -- there is better than I think anybody was anticipating. What's underlying that and you know how should we think about that going forward maybe even beyond 2023?

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Yes, Ron, you are stating it accurately. The performance there has been better even than we expected and it's largely driven by more success in competitive wins than we had anticipated. Generally, in all of our business, we project a certain amount of success, particularly, in competitive environments. And here, we've just done better than we anticipated, and so that's driven sales upside and a very strong book-to-bill that we've had in that business to where their backlogs now is more than 3 times sales and supports our projections for long term, steady and durable growth.

Ronald Epstein
Analyst at Bank of America

And then you mentioned in your -- just as a follow on, in your prepared remarks that your growth has been supported by your ability to hire folks. How's that been? I know, I mean, it kind of across the entire industry and your supply chains getting labor has been difficult, and particularly skilled labor that's kind of up the spec. And how have you guys have been able to do that and what's underlying that?

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

It has been a key driver to generating 16% sales growth in the fourth quarter, in particular. We noted in the third quarter of last year that we were starting to see labor trends change in a favorable way, our hiring had improved, our retention had dramatically improved, and we saw that trends continue in the fourth quarter.

I think a few things contribute. We hire technology skills that are very akin to what the technology sector employees and we've certainly seen softness in that sector that has led to a significant increase in applications to Northrop Grumman. But I'd also like to think it's due to the reputation of our company as being a technology innovator and the successes that we were able to showcase last year like James Webb and the unveiling of B-21 really spiked interest in applications to for employment at our company. And so those two things in combination are certainly working in our favor in a differentiated way.

Ronald Epstein
Analyst at Bank of America

Great, thank you.

Operator

Thank you. One moment for our next question. Our next question comes from Sheila Kahyaoglu with Jefferies. Your line is open.

Sheila Kahyaoglu
Analyst at Jefferies Financial Group

Good morning and thank you. Just a follow up on an earlier comment. You know, in the past, I think you've talked about 12% margins in 2024 and the 2023 guide is 11.5% or so. You know, as you think about sort of inflationary pressures, what are you watching? And you mentioned some of the B-21 items as an example. So what sort of offsets that to get to that 50 basis points of expansion?

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

So as we've noted, we had talked about 12% being the fundamental margin rate that we believe this business, this portfolio can perform at, and that we would be working our way back to that as particularly mix becomes less of a headway -- headwind in the middle of the decade. We still see that. But we are having these temporal pressures related to inflation that are flowing through all of our programs, B-21 most notable because of its scale and that we did it so very long ago.

And as we think about how we are offsetting those costs, we talked about some of those ways today. We are working to digitally enable our business, which reduces program costs directly and improve profitability. But we also are applying that to our back office to streamline business processes and reduce costs that flow into our overheads also making our rates more competitive and reducing the impact of cost growth. So those things that real estate has been key. You saw today, we talked about a few things that we did in the real estate area already in 2022, but we have many more of those lined up as ways to continue to offset any cost growth that we see and drive towards those higher margins.

Sheila Kahyaoglu
Analyst at Jefferies Financial Group

Great. Thank you.

Thank you. One moment for our next question. Our next question comes from Richard Safran with Seaport Global. Your line is now open.

Richard Safran
Analyst at Seaport Global Securities

Kathy, Dave, Todd, good morning.

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Good morning.

Richard Safran
Analyst at Seaport Global Securities

I think we probably all agree the stock right now seems to reflect the idea that defense is going to be a bill payer as we move to a period of deficit reduction. And -- and I realize this question puts you a little bit on the spot forecasting government spending. But -- but I wanted to know if you'd expand on your optimistic opening remarks, talk about your macro outlook relative to what seems to be being priced into your stock? And if you think modernization might be sacrificed, you know, as part of the budget negotiations?

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Yeah. So we look at the stock price over a longer time horizon, then weeks and we've consistently outperform -- outperformed the industry on a relative TSR basis over the long term. But as you indicate. We've seen some pullback in the last several weeks across the sector and even more so with Northrop Grumman. I am a little surprised at the level of relative pullback we've seen given our strong continued results, our growth outlook and the relative portfolio positioning that we have in the US and internationally.

And to answer the second part of your question directly, I do not see the US or our allies pulling back on funding their national defense strategy that is well aligned with the Northrop Grumman portfolio. So, you know, I'd sum it up by saying, with a strong backlog, growing global demand for our products, differentiated technology and the ability to attract and retain top talent, we're really well-positioned to continue executing on the strategy that we have that is expected to deliver differentiated growth and a potential to generate greater than 20% free cash flow growth for at least the next several years, and we believe beyond. So I think investors are going to like that.

And we've been in periods like this before following sequestration, where there was noise in the system related to the government's commitment to national security. But following that, it was one of the best periods of relative TSR growth at our company, and really, our industry has produced in a while. So I see this as -- as a temporal speed bump in our past and yet our strategy remains strong to deliver value.

Richard Safran
Analyst at Seaport Global Securities

Thanks. Just as a -- a quick follow-up on inflation. The comments on the B-21 that you've been making, is there a general trend here is -- when your contracts you're signing right now with the government, are they generally accounting for inflationary effects or are you not finding that?

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

So, you know, our customers are engaging in conversations with industry to understand ways to motivate our investment in future capability and capacity, that is what they really want. And I think many of them now understand that shifting too much risk to industry doesn't support that investment, nor does it deliver the capability they need in a timely fashion. So with that, I expect we're going to see less the price development going forward. And they are specifically to inflation the industry broadly is pushing back on accepting the long-term fixed price contracts right now. And they're asking for reopeners for inflation. We expect that to continue. And as our suppliers ask us for that, we, of course, are passing that on to the government. And really, that's just common sense. So I believe it will become the norm.

Richard Safran
Analyst at Seaport Global Securities

Thank you for that. I appreciate it.

Operator

Thank you. One moment for our next question. Our next question comes from that was Douglas Harned with Bernstein. Your line is now open.

Douglas Harned
Analyst at Sanford C. Bernstein

Good morning. Thank you. And you know, last -- last year you had a decline in Aeronautics that -- that we understood pretty well because you've got quite a few legacy programs that we're ramping down like JSTARS, Global Hawk. And when you look at this year with your fairly flat guidance for -- for Aeronautics. How do you look at the pluses and minuses when we look at B-21 growth, but you still got some legacy programs that are declining? How do you see those offsetting each other?

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

So Doug, this year is really a continuation of those same trends flowing through the top line. The programs that have been declining. We've seen the majority of those declines, but they do still flow into the 2023, 2022 compare. So it is things like Joint -- Joint STARS and Global Hawk. F-35 being a big revenue contributor in AS is relatively flat. So that ties directly into the narrative about their revenues being flat. And then B-21 is an increase, but it's not a significant increase yet because we're just moving from EMD into LRIP and those two combined are not a significant increase in the program as of yet.

Douglas Harned
Analyst at Sanford C. Bernstein

Well, and then on a slightly different topic. When you look at rocket motors, and this is an important area for you. And I'm trying to picture what the growth trajectory looks like. And also just in a sense of your market share, you've got one competitor that is a mature player. There are new entrants coming into the space. How do you see the long-term evolution of your market share and how you're positioned in that area?

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

So we stay focused on investing in the future capability needed and more so lately in the capacity needed. And in many ways, the reason we are being asked to take on more share of the market is because we've been investing in this business and are able to take on that additional business because we have outfitted our manufacturing facilities to support the growth. As what the government is asking, we have been responsive.

And so as a result, we are winning more business in that area. But we expect to be able to compete even as other new interest come into the space because we do have a long heritage of expertise that contributes to our solid rocket motor business, and that's for all size. I talked today and highlighted some of the larger solid rocket boosters that we build in support of SLS and GEM63s for Kuiper. But that's true in businesses like GMLRS, where we are taking on more of the needed capacity because we've been investing in our manufacturing capacity there as well.

Douglas Harned
Analyst at Sanford C. Bernstein

Very good. Thank you.

Operator

Thank you. One moment for our next question. And our next question comes from Seth Seifman with JPMorgan. Your line is open.

Seth Seifman
Analsyt at Northrop Grumman

Okay. And thanks very much and good morning. I wonder if you could talk a little bit about the -- the profitability in the -- in the space business. I mean, the margin guidance came down there or margin rate guidance came down there a couple of times during the year. And you know, it's kind of perceived to be kind of a 10% business, I think, is what we've talked about in the past and looking to a second year in the mid-9s here in 2023. And so what's changed there over -- over the past year?

Dave Keffer
Corporate Vice President and Chief Financial Officer at Northrop Grumman

Hey, Seth. It's Dave. So I think you pointed out accurately that we're now projecting a margin rate for space in the mid-10s going forward. There were a lot of puts and takes in that margin rate upward and downward throughout 2022. Obviously, it's a rapidly evolving business, a tremendous amount of backlog growth and new program activity added into that portfolio over the last couple of years. So we're really pleased with the volume we're adding both at the top line and the bottom line in that process. And obviously, a lot of new cost type work being added to that portfolio and that mix growing, but also work that will evolve toward fixed price over the next couple of years and some new fixed price programs in that mix as well.

So in aggregate, we think the mid-9s as the right way to look at 2023. In the coming years, we do see the opportunity for margin rate expansion. But I think the most important takeaway for the space business is that the volume of top and bottom line growth that we've been delivering over the last couple of years and now are projecting over the next few is -- is really adding a lot of value there.

Seth Seifman
Analsyt at Northrop Grumman

Okay. Okay. Great. And then just as a follow-up, Dave. So the working capital performance was -- was quite good in 2022. I think the way that our measuring here, working capital actually came down a bit despite the growth and despite the tough operating environment, you know, only 6% of sales, which is below some of your peers. And what's the opportunity from here? Or is there kind of a normalization at some point where actually for a growing business the normal level of working capital is -- is higher?

Dave Keffer
Corporate Vice President and Chief Financial Officer at Northrop Grumman

Sure. Let's talk about that for a few minutes. You know, there is not a substantial change in working capital projected in the three-year free cash flow guide that we gave today. There is more capital intensity in 2023 and 2024 that we've signaled throughout this year, given just how much more new business we were awarded this year and the additional capital investments that we need to make to support capacity and capability there.

We've talked about things like the Amazon Kuiper Award and -- and other areas of the business that Kathy just noted that -- that we're making investments upfront for these long-term franchise programs. So that is a headwind to free cash flow. But we're pleased to be able to offset that and deliver free cash flow guidance for 2023 that's in line with our prior expectations. That's supported by the growth of the business, both top and bottom line. The R&D tax numbers will -- with come down steadily over the next five years. And then gradually, over the next several years, we'll see improvements in the CAS pension cost reimbursement based on current projections.

So not much change in working capital, but there are some other moving pieces in the mix. I think importantly, when we look at the underlying fundamentals of growth and margin rate, as we talked about in our scripted remarks, we do anticipate growth through this three-year outlook that we've provided at the top line, and we are modeling small but gradual improvement in the margin rate as well. So that's a healthy underlying condition for free cash flow.

And while we're at it, as we think about the -- this outlook for free cash flow, the foundation is set for strong free cash flow beyond this three-year period. The second half of this decade will have more programs moving to production, fewer of these upfront investments required to do so. The foundation we've laid over the last several years of capital investment is going to pay off in the second half of this decade on many of those programs. And so that's a healthy environment for continued growth in free cash flow, as well as the continuation of the R&D tax amortization rolling off as a -- as a headwind. So when you look at the second half of the decade, I think your expectation should be more of the same strong growth in -- in free cash flow that we've been talking about in the first half.

Thank you. One moment for our next question. And our next question comes from Myles Walton with Wolfe Research. Your line is now open.

Myles Walton
Analyst at Wolfe Research

Thanks. Good morning. I did have a couple of follow-ups on the -- on the B-21, if that's okay. And Dave, I think you alluded that the first LRIP contracts to be awarded in 2023. And I'm just curious, is that -- is that sort of the triggering event or whether or not you'd know you're -- you're in the loss or not at that point? And then Kathy, I know you said the 10-K disclosure is over the five LRIP lots. But I'm just curious, is it -- is it tougher at the front end of those lot profiles? Is it -- is it more promises at the back end that you'd have time to fight off inflation? Anything on those two fronts? Thanks.

Dave Keffer
Corporate Vice President and Chief Financial Officer at Northrop Grumman

Sure. I'll start on -- on your first of those questions. And the award of that first lot of LRIP will be your noteworthy event but not a triggering event of any kind from an accounting perspective. We -- we will update our projections quarterly as we have been. We'll continue to do so. And so at this time, we don't believe that a loss is probable, and therefore, we have not booked one. We do believe that a loss is possible, which is why we're -- we're including it in our remarks and our 10-K disclosures. It's something we will continue to work over time. Obviously, this is -- is going to continue for a number of years. As Kathy has talked about, we'll continue to do everything we can to mitigate inflationary pressures and work with our customer and our suppliers in the process.

Kathy, anything you'd like to add?

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Sure. So in answer to your second question, we do expect to have a better sense as the year progresses, and we'll update disclosures as we do. And as we look at the profile, there's nothing really notable. To your point, we have more time to work cost efficiencies in the later lots. But of course, we made some more aggressive assumptions about learning curves and the like as we would on any production program. So really nothing notable in the profile and how you might think about any potential loss in spread.

Thank you. One moment for our next question. Our next question comes from Robert Stallard With Vertical Research Partners. Your line is now open.

Robert Stallard
Analyst at Vertical Research Partners

Thanks so much. Good morning.

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Good morning.

Robert Stallard
Analyst at Vertical Research Partners

Dave, I've got a couple of cash flow questions for you. And first of all, on basically cash taxes with the R&D tax legislation impact. What sort of tailwind are you expecting from this -- from 2023 and onwards? And then secondly, what are your assumptions for equipment sales in that -- that cash flow guidance for 2023 or for the whole period? Thank you.

Dave Keffer
Corporate Vice President and Chief Financial Officer at Northrop Grumman

Sure. Thanks for those questions. The answers are pretty straightforward. As we noted, the impact on our cash taxes in 2022 from the R&D tax legislation was just under a $1 billion. We would anticipate that being about 20% less per year, just under $200 million or so on average less per year. And so that is a -- the magnitude of the annual tailwind that we'd anticipate for the next five years or so.

And overall, cash taxes, excluding the impact of -- of that R&D tax amortization will increase slightly over the coming years, but -- but that's factored into our -- our multiyear outlook. And as for equipment sales, I appreciate the question there. We received the final payment associated with the equipment sale that we booked a couple of years ago in 2022. And so we don't anticipate we're having our multiyear cash flow outlook, any continued recoveries from equipment sales.

Thank you. One moment for our next question. Our next question comes from the line of Cai Von Rumohr with Cowen. Your line is open.

Unidentified Participant
at Northrop Grumman

Yeah. Hey, guys. This is actually Jack on for Cai today. And thanks for the question. And just a quick question back to kind of the Section 174. Dave, I know in the past, I'm not sure if you quantified that if you could actually provide that dollar figure if you could. I know it steps down 20% each year. But looking back at your guide from last year at this time for 2024, it looks like a larger delta than an implied $700 million headwind. So just to confirm, is that incremental capex going high -- higher? Or if you could just provide some color there, that'd be helpful. Thanks.

Dave Keffer
Corporate Vice President and Chief Financial Officer at Northrop Grumman

Sure. I appreciate those questions. I think you have to the -- the air math about right on Section 174. It was just under a $1 billion in 2022, and it will decline by just under $200 million a year on average going forward. And in terms of that 2024 guide, you're right that our capex expectations increased a bit given the volume of new business that we won this year that we'll be investing in going forward. No other material changes to 2024. We do anticipate growth as we've seen in 2024 and then a real ramp in 2025 as capex begins to decline, and you have the tailwinds as well in 2025 and beyond from R&D tax, CAS pension, recoveries and the underlying growth in margins in the business.

Peter Arment
Analyst at R. W. Baird

Hey, Kathy, and within Aeronautics, does the service mix continues to be a bigger part of the story? I guess it's now about 22%. If you finish 2022 and look, that's up from the mid-teens the last few years. Obviously, there's some puts and takes on why that is. But just wondering if this trend is going to continue and how you think about the impact on margins? Thanks.

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Yeah. So we do expect the trend to continue in terms of -- as assets get into service, we continue to support them. But we also have assets like Global Hawk that are coming down. So I don't see a material change in that mix as we look forward, Peter.

Thank you. One moment for our next question. Our next question comes from the line of Ken Herbert with RBC Capital Markets. Your line is open.

Ken Herbert
Analyst at RBC Capital Markets

Yes, hi, good morning. Kathy, in your opening...

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Good morning.

Ken Herbert
Analyst at RBC Capital Markets

...in your opening comments, I think you -- you maybe called out international opportunities, perhaps a little bit more than I can remember from recent quarters. Can you -- can you help frame maybe how much of an uptick in international opportunities could be reflected or international sales could be reflected in the 2023 guide, if that was all a part of any of the upward revision? And then as you think about beyond 2023, how meaningful is international in terms of an uptick for you? I know historically, obviously, it hasn't been as meaningful part of the mix of some of your peers, but maybe you can comment on that expanding opportunity set?

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Yes. Thank you. So in the fourth quarter, we did see some meaningful uptick in Defense Systems, and you can see that reflected in our results, both from the areas that I outlined in this call related to ammunitions and armaments but also increased interest in IBCS, and we have the current Poland work continuing to ramp but the 10 additional countries that I've noticed that have expressed interest. So as we think about the near-term drivers, it's the things that we already have in production. But as we think about the longer-term drivers is areas like IBCS future sales.

And we are seeing that interest increase across the business, but most notably in 2023, I think you will see that reflected as upside opportunity in defense. As we look at the enterprise over the next several years, we do expect our international growth rate to be double digit, low-teens compared to a US growth rate that's more in the norm of our mid-single digits. So as we think about international, we do expect it to grow as a percent of our portfolio in the next several years. And that's all based on international demand growing as a result of increased spending confirmations made by our allied partners.

Thank you. One moment for our next question. Our next question comes from Scott Deuschle with Credit Suisse. Your line is now open.

Scott Deuschle
Analyst at Credit Suisse Group

Hey, thank you and good Morning. Kathy, if I go back to 2018 when the group sold off quite a bit, Northrop got pretty active on buying back stock. And I think you even launched an ASR, if I recall correctly. So I'd be curious if that would still be your playbook this year if the valuation continues to come down? And whether you might lean on the balance sheet to do so just given the track record of having run a valuation-sensitive buyback program? Thank you.

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Yeah. Well, as you note, we have used ASRs as the tool in the past. And as we indicated in the call today, we do plan to put more than a 100% of our free cash flow back into the deployment to shareholders. The fact that our valuation is down, really, we don't try to time the market per se. But we do think about that as we are kind of weighing our options for capital deployment this year, and we do have the flexibility to increase share repurchase from our original plan. So that is something we're actively contemplating.

Scott Deuschle
Analyst at Credit Suisse Group

Great, thank you.

Thank you. One moment for our next question. And our next question comes from George Shapiro with Shapiro. Your line is now open.

George Shapiro
Analyst at Shapiro

Thank you. Dave, I had one for -- one for you. In the operating income discussion in space, you had a big gain, $45 million charge. And you said it was all -- the $96 million gain only partially offset the lower EACs. When I look at the K for the year, you had minus $38 million in space versus a $134 million last year. So if you kind of just discuss what happened in the quarter and just why such a significant change year-over-year?

Dave Keffer
Corporate Vice President and Chief Financial Officer at Northrop Grumman

Sure. Well, it's a great question, George. You know, clearly, that's an indication of the broader macroeconomic conditions that we in -- in our industry, and frankly, most other industries were facing in 2022, and in our business, it impacted the level of net EAC adjustments in really each of our sectors in different ways. And you see it acutely there in space, as you mentioned. A number of those EAC adjustments were in the fourth quarter. And that kind of -- the net of all those puts and takes to include the inventory adjustment on a new commercial product line that you mentioned was another downside in Q4. Those were roughly offset by the upside from the land exchange transaction in space.

So a number of puts and takes, but when you net it all out, not much overall impact on the space margin rate in Q4 or for the year. We're -- we're forecasting a rate just above that level that we operated at in 2022 as we now look at 2023. And as I noted earlier, something in the mid-9s is our kind of going forward expectation for 2023 margin rate in space.

George Shapiro
Analyst at Shapiro

But Dave, it's still unusual to see negative EACs, you know, for the year. So I was just wondering, are there any specifics that you could point to maybe it was for the year or just for this quarter?

Dave Keffer
Corporate Vice President and Chief Financial Officer at Northrop Grumman

No single item was a driver of that of much more significance than any other. I think that alone, George, is an indication of the fact that this was more in the -- in line with broader macroeconomic pressures as opposed to any performance issue or contract issue in any particular program. This was broader and more widespread, but -- but not significant on any one program in and of itself. And again, I think really just indicative here of the environment we were operating in, in a business with a lot of programs, a lot of new growth in recent years to be excited about.

George Shapiro
Analyst at Shapiro

Okay. And then just one general one for you, Kathy. I mean, with the better sales growth you're guiding to in 2023, a result of the budget or new awards won or both? And then also, yeah, with 16% sales growth in Q4 and outlay is likely to grow 7% or 8% in 2023 based on the budget investment authority of 15%. Why does the growth rate slow that much in 2023? I mean why wouldn't it be higher than what you're suggesting? Thanks.

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Yes. So as we noted throughout 2022, if we could break loose supplier deliveries and continue to improve labor trends, we could deliver accelerated growth. And fourth quarter exemplified a path to doing just that. As we come into 2023 with that momentum, the same holds. We are confident enough in our sales expectations as we sit here today to raise them above what we had said in October, largely because we are seeing those improvements in labor in particular. And if those trends continue, we would have opportunity to even further accelerate growth in 2024. We -- the budget does not play into this. We had assumed strong budget growth. It, of course, came to fruition in the 2023 budget, and we continued to believe the 2024 President's budget will also show growth.

George Shapiro
Analyst at Shapiro

Operator

Thank you. One moment for our next question. Our next question comes from the line of David Strauss with Barclays. Your line is now open.

David Strauss
Analyst at Barclays

Great, thanks for fitting me in. And a lot of discussion on B-21 and EMD and LRIP. Just how should we think about what happens to AS margins over the next couple of years as I assume EMD flans out or starts to come down where you've been taking positive adjustments and LRIP ramps up from here? Thanks.

Dave Keffer
Corporate Vice President and Chief Financial Officer at Northrop Grumman

Sure, David, I'll start on that one. You know, our margin rate was particularly high in AS in 2022. That was driven in part by the strong performance on those EMD profit pickups associated with anticipated incentives on that part of the program. And we projected a 10% or so level for AS margins in 2023 and expect that, that's a reasonable kind of planning assumption at this point for 2023. And as we look forward beyond that, a lot of the factors that are working into the 2023 estimate would be those that we'd expect to continue beyond 2023. So of course, we'll update you over time.

You mentioned B-21 EMD program will or a portion of the contract will continue for a number of years on LRIP. We haven't baked any margin or cash in that part of the program into our multiyear outlook or our 2023 guide. And so we think that 10% level is the right way to think about kind of the underlying margin rate in AS in the near term.

David Strauss
Analyst at Barclays

Okay. And Kathy, maybe -- maybe your thoughts on what -- what bookings could look like this year, what you're anticipating for, you know, the book-to-bill this year? Thanks.

Kathy J. Warden
Chair, Chief Executive Officer and President, Director at Northrop Grumman

Yeah, David. So we had projected book-to-bill to be light in 2022, and it turned out to be 1.07. We are projecting it to be light again in 2023. I've noted before, we look at this over a multiyear period. We've been running at 1.2 for the last four years aggregated across those four years. So we still expect to be well over 1 when we think about a five-year aggregated book-to-bill, but we do expect 2023 to be less than 1.

David Strauss
