Everyone and welcome to the General Dynamics First Quarter 2019 Earnings Conference Call. All participants will be in a listen only mode. After today's presentation, there will be an opportunity to ask Please also note today's event is being recorded. At this time, I would like to turn the conference call over to Howard Rubel, Vice President of Investor Relations. Please go ahead.
Thank you, Jamie, and good morning, everyone. Welcome to the General Dynamics' Q1 2019 conference call. Any forward looking statements made today represent our estimates regarding the company's outlook. These estimates are subject to some risks and uncertainties. Additional information regarding these factors is contained in the company's 10 ks and 10 Q filings.
With that, it's my pleasure to turn the call over to our Chairman and Chief Executive Officer, Phoebe Novakovic.
Thanks, Howard, and good morning all. Earlier today, we reported earnings of $2.56 per diluted share on revenue just shy of $9,300,000,000 operating earnings of slightly over $1,000,000,000 and net income of 7.40 $5,000,000 Revenue was up 23% against the Q1 of 2018 due in large part to the acquisition of CSRA. However, without CSRA revenue was up an impressive 9.6% on a purely organic basis. In fact, there was organic revenue growth across all 5 operating segments. EPS of $2.56 was 0.14 dollars better than consensus.
It would appear that revenue was some $400,000,000 higher than anticipated by the sell side and operating earnings were about $40,000,000 higher. Operating earnings of slightly over $1,000,000,000 were just ahead of the year ago results despite modest declines at aerospace, marine and combat systems. The results benefited from the combination of CSRA with GDIT. While the operating margin of 10.9% in the quarter was good, it did not compare favorably to last year's stellar first quarter of 13.4%, which was before the inclusion of amortization from the CSRA transaction. Net earnings were down $54,000,000 over the same quarter in 2018.
Higher interest expense, somewhat higher taxes were the cause of the lower net income. It follows that earnings per share from continuing operations were $0.09 below the Q1 of 2018, a 3% drop. Apart from the impressive revenue growth, an important part of this story in the quarter was order intake and growth in backlog. Total backlog grew to $69,200,000,000 an increase of $1,340,000,000 compared to the end of last year. Excluding the impact of foreign exchange, the book to bill for the company was an impressive 1.2, broken down into 1.1:one for Defense 1.4:one for Aerospace.
So let me discuss each group and provide some color where appropriate. First, aerospace. Aerospace revenue of $2,200,000,000 was $450,000,000 or 22.7 percent ahead of the year ago period. This is attributable in large part to the delivery of 7 gs500s in the quarter and a solid increase in service revenue. The moderately lower operating earnings were related to the mix shift at Gulfstream from the delivery of the GE 500.
These planes carry the burden of the test program and retrofit as we previously advised. Margins on the aircraft will improve markedly through the year. At year end, we had indicated that Aerospace margins for the 1st two quarters would be in the mid-fourteen percent range, up somewhat from the 14.1% rate in the final period of 2018. At 14.6%, the margin Based on our delivery profile and cost improvement, we continue to expect overall margins to improve, particularly so in the second half of the year. On the order front, activity in the quarter was very good.
The book to bill at Aerospace was $1.4 to $1 denominated. The Gulfstream book to bill was even better. We grew the backlog for the G650 and also expanded the G500 and G600 backlog. For the trailing 12 months, Aerospace book to bill was about 1.1:one. You can see more information on quarter's deliveries and orders in Exhibit J to the press release.
We anticipate the G600 will be certified late June, but timing is difficult to predict given the FAA's rigorous review process. Nonetheless, we expect certification of the 600 this quarter or early next deliveries will remain on track for the second half. While the pacing items for deliveries on the 5 100 and 6 100 is our ability to deliver nacelles, this is becoming less of an issue as you can discern from deliveries of the G500 in the Q4 and the last quarter. Nacelle costs are increasingly under control and we are producing very good quality. We expect all schedule issues to be behind us by mid year.
So forgive me this commercial plug, but earlier this month, the G650 shattered a record for speed and range demonstrating its unrivaled performance. The aircraft flew 8,379 nautical miles from Singapore to Tucson in 15 hours and 23 minutes, averaging Mach 0.85, beating the record set just a few weeks earlier by the competitor's aircraft by 44 minutes. It is also interesting that the G650 traveled during that flight approximately 227 nautical miles further than the competitor's aircraft in considerably less time. This is to our knowledge the longest distance ever flown by any business aviation aircraft. This is of a particular interest to customers who think that the range and speed at that range is of vital importance.
Next Combat. At Combat, revenue of $1,600,000,000 was $13,600,000 above the year ago quarter. On the other hand, operating earnings declined $18,000,000 with an operating margin of 12.6%. Mix was a large factor behind the results. There was strong growth in the Abrams program and a ramp up of mobile protected firepower and other new program.
Stryker volumes were down, but we ascribe that to timing. Munitions also delivered growth. We also took a one time charge in the quarter related to the disposition of a legal dispute over the closeout of a lease at one of our former European operating sites. Absent that one time item, earnings for the segment would have been up year over year. The diplomatic issues that have slowed production on the international vehicle program in Canada are in the process of being resolved.
Once resolved between the two countries, we will see a reduction in operating working capital and the corresponding increase in cash receipts. Backlog for this segment is lumpy with the 4th quarter traditionally seeing the highest order activity in the Q1 the slowest. This year was no exception. The $2,200,000,000 in orders received in Q4 followed by the approximately $1,200,000,000 in orders received this quarter gives us good line of sight for our production planning and continuous improvement methodology. Of note, Stryker backlog grew in the Q1 and the Army added funding to the SET V4, the next generation of the Abrams main battle tank.
Stryker is flexible platform and the Army continues to find additional systems and weapons that we are integrating onto the vehicle. Integration of new capabilities onto our vehicles leverages our investment. Our intimate knowledge of the platform ensures that the Army receives its programs reliably and affordably. We also continue to see opportunities to expand the opportunities throughout NATO and Eastern Europe as well as the Pacific region. Next Marine Systems.
Marine revenues at $2,100,000,000 was up slightly and operating earnings of $180,000,000 were down $4,000,000 against the year ago quarter. Operating margins were 8.7 percent with our guidance for the year at 8.5%. We are modestly ahead of target. We have delivered the 17th ship of the Virginia class program and have another 11 in various stages of construction. With respect to Columbia, we are 97% complete with the detailed design and nearly 43 percent complete with the construction design drawings.
We will be at 83% complete at the start of construction, far in excess of historical design completion metrics for any class of warships. We have begun long lead material construction on Columbia and will begin full construction at the 1st ship late next year. In response to the significant increase in demand from our Navy customer across all three of our ship yards, we continue to invest in each of our yards with particular emphasis at electric boat to prepare for the higher production associated with Block V of the Virginia program and the new Columbia ballistic missile submarine. As you may recall, both Columbia and the Block V represent a significant increase in size and performance, requiring additional manufacturing capacity and different logistics infrastructure transport the larger modules from Quonset Point to the waterfront at Groton for final assembly and test. CapEx in 2018 for Marine Systems was $243,000,000 more than double its depreciation for the year.
For 2019, we again expect the Marine segment to command the largest share of our capital budget, about half of our entire CapEx. So, defice it to say that we are poised to support our Navy customers as they seek to increase the size of their fleet. Next, information technology. For the quarter, IT generated revenue of $2,200,000,000 and operating earnings of $156,000,000 with an operating margin of 7.2%. Since the numbers for the Q1 2018 did not include CSRA, comparisons to the year ago quarter are not meaningful.
Revenue of $2,200,000,000 is up by over $1,000,000,000 but is down about $200,000,000 sequentially, over half of is attributable to the divestiture of the call centers and the remaining to the wind down of several mature programs replaced by the ramp up of new programs. Margin of 7.2 percent is lower than Q4 due to mix, but a bit better than Q2 and Q3 of 2018. If you look at our EBITDA margin, it is 12.4%, including state and local taxes in the operating results. If these taxes were carried below the line as in the case for most competitors in this segment, it would add approximately 50 basis points to our results. This places the business in the best in class category for its industry.
The integration has gone well and is a bit ahead of the plan we put in place last year. We are taking the best of the 2 legacy companies and building a highly competitive enterprise with the scale and the resources to create value for our customers and our shareholders. GDIT's book to bill for the quarter was 1.1:one and for the trailing 4 quarters, it is over 1:one. This business is growing and is positioned for growth going forward. The Q1 included some notable wins, a $490,000,000 contract from DISA to support Pentagon network infrastructure, dollars 125,000,000 for helicopter training and simulation at Fort Rucker, dollars 580,000,000 for several classified programs and a myriad of additional wins across the portfolio.
Finally, for Mission Systems, revenue rose by 5.5% compared to the year ago quarter, while operating earnings of $148,000,000 were $2,000,000 higher than the Q1 of last year, with a 50 basis point decrement in operating margins attributable solely to mix. Book to bill for the quarter was 1x following 1 to 1 book for bill for this for each of the last two years. As you can see, we ended the quarter with a backlog of $5,300,000,000 essentially level with the prior quarter and with the year ago quarter. Demand was broad based across many of their space and naval programs. Army Ground Systems activity was particularly strong.
So in my view, we were off to a good start to the year. The story in the Q1 was about revenue and backlog growth. Orders of $10,700,000,000 across our businesses provide us with good operational visibility. Our ongoing focus on productivity provides the opportunity to deliver very good results. As we begin this quarter, we expect our 2nd quarter performance to be very similar to the first quarter from an EPS perspective.
You may recall that we do not as a practice change guidance at the end of the first quarter. It is our practice to give you a full review of our expectations at midyear at midpoint during the year. Suffice it to say that we are a bit ahead of the operating plan upon which our guidance was based. As always, we will work to consolidate our improvement and strive to continue to improve our results. Let me turn this over to Jason for additional commentary and then take your questions.
Thank you, Phebe, and good morning. Net interest expense in the quarter was $117,000,000 versus $27,000,000 in the Q1 of 2018. The increase in 2019 is due to the debt we issued to finance the acquisition of CSRA. We're also carrying more commercial paper than anticipated due to delayed payments on one of our large international vehicle programs in Canada. Our free cash flow of negative $976,000,000 was impacted by these payment delays.
And as we've discussed previously, this is a timing item. On the capital deployment front, capital expenditures of $181,000,000 in the quarter were up about 75% from the year ago quarter as we invest in our shipyards to support the significant growth that's on the horizon. We still expect this year to be the peak at approximately 3% of revenues and returning to the 2% range thereafter. In the quarter, we paid $268,000,000 in dividends and we spent $86,000,000 on the repurchase of 525,000 of our shares. We plan to acquire enough shares in 2019 to ensure there is no dilution from the exercise of employee stock options.
Otherwise, we anticipate deploying the balance of our free cash flow this year to pay down our short term borrowings. We ended the quarter with a cash balance of $673,000,000 on the balance sheet and a net debt position of $12,900,000,000 Our effective tax rate was $9,000,000,000 Our effective tax rate
was 18.6 percent for the
quarter, which is consistent with our full year tax rate guidance. As Phebe noted, order activity and backlog were a particularly strong story in the quarter, as 4 of our 5 segments posted a book to bill of 1 to 1 or greater, even as we grew almost 10% organically. On that note, I think it bears a reminder that not all companies report book to bill on the same basis. We calculate this measure based on the firm backlog as reported under generally accepted accounting principles, excluding the value associated with IDIQ contracts. That's of course most relevant to Mission Systems and GDIT, each of which had a book to bill of 1 to 1 or greater even under the more conservative GAAP definition.
We finished the quarter with a total backlog of $69,200,000,000 that's up 2% over year end 2018 and up 11% over this time a year ago. The total potential contract value, including options in IDIQ contracts, was $103,000,000,000 consistent with year end and up almost 18% over a year ago. There's one final item I'd like to highlight. We adopted the new lease accounting standard effective January 1 this year on a prospective basis. We recorded a $1,400,000,000 liability for our operating leases along with a corresponding asset.
This creates a visible change in our other assets and liabilities on the balance sheet, but otherwise has no impact on our net earnings or cash flows. Howard, that concludes my remarks. I'll turn it back over to you for the Q and A.
Thank you, Jason. As a reminder, we ask participants to ask one question and one follow-up so that everyone has a chance to participate. Jamie, would you please remind participants how to enter the queue?
Ladies and gentlemen, at this time, we will begin the question and answer session. Our first question today comes from Doug Harned from Bernstein. Please go ahead with your question.
Yes. Good morning. Thanks.
Hi, Doug.
Hi. I wanted to see if we get a little better understanding on the margin trajectory at Gulfstream. You talked before in the last quarter about the lower margins at the beginning of the year and likely very attractive margins when you get out to Q4. Could you give us a sense of what's behind that trajectory and are those higher margins at the end of the year? Are those the sort of normal margins that we might expect going forward beyond this year?
As I said in my remarks, the margin rate is largely attributable to the mix. And as we've talked about, fairly frequently, that mix is driven by the increased or increased deliveries on the G500, which carry lower margin in that first accounting lot. But we're going to be through that in the Q2. And look, I think we've been pretty, quite transparent about this change in mix. We'll work our way through it as we deliver more G500s and the G600s will enter into service with good margin.
So when I think about it, our margins will improve throughout the year. And as we go into next year, our performance will get even better and better. As we hit full rate production on the 50,600 and continue to come down our learning curve.
And then when you get out there and the 50600 are mature, is it possible to give us a sense of how you might think about that between sort of G550 mature margins and G650 mature margins? Where will the 5 100 and 600 shake out?
Well, the G650, nothing is going to come close to that for I think all the reasons you understand, but it is our expectation that the G500 and G600 surpass the G450 and G550 peak margins. They're built and purpose built facilities are coming down straight lines and we have over that time continue to perfect our manufacturing processes. So when we're up and really, really running, I think we're going to be better than those 2 legacy airplanes.
Okay, great. Thank you.
Our next question comes from Robert Stallard from Vertical Research. Please go ahead with your question.
Thanks so much. Good morning.
Good morning.
Phebe, just to start off with Aerospace. You noted the good demand for the G650 in the quarter. Are you still going to stick with your plan to gradually ease 650 deliveries over time?
Yes. So a little bit this year and then more in next year and the following year when 500s and 600s are in, as I say, full rate production with good margins. Okay.
And then as a follow-up on GDIT, you noted a good book to bill in the quarter. How sustainable do you think this is? And what's the expected conversion of that book to bill to revenues over time?
Well, when we put something in firm backlog, it's a pretty sure conversion into revenue. But let me give you a little bit of context, Dirk, because I think it helps to understand. So DDIT, in the quarter at a 1.1 to 1 book to bill and over the last four quarters as I mentioned in my remarks, they had a 1 to 1. Now their win rate, they have demonstrated a win rate consecutively over those last four quarters between 70% 75%. Against those performance indicators, you've got a budget that is growing by 5%.
So I think this business is in very good stead for continued growth.
Okay. Thank you very much. Our next question comes from Ronald Epstein from Bank of America Merrill Lynch. Please go ahead with your question.
Hey, good morning.
Hi, Ron.
Maybe a bigger strategic question. How are you thinking about Mission Systems, right? I mean, their performance in the quarter was pretty good. And how do you think about growing that? Or it seems like it's subscale right now, right?
Do you grow it? Do you sell it? What do you do with it? I mean, when you think about it.
So given its portfolio, I don't believe that it's subscale. If you think about what they really are is they are systems integrator with a significant products business. They've got some long term franchise programs, a number of them and those programs are growing. So I like where they are. They've got some unique positioning, in fact, best of class positioning in a number of areas, in network security, cyber protection, accuracy and position navigation in a GPS environment, integration of systems on the ballistic missile class submarines and the fire control systems.
So they assess something. These are programs that they've had for a long, long time, all of which are on growth trajectories. So I don't really see that them as subscale. And again, their margins are really quite nice. This is a good operating leverage company.
I think they play nicely in the space they're in and we're quite comfortable with
it. Okay, great. And then maybe just one follow on in aerospace. Can you say when is the next available delivery slot for 650?
Yes. I'm not getting into that anymore because we're really not tracking it that way. We've got a whole lot of new airplanes coming on. So those individual metrics become a little less meaningful. But you need to think about what's really unusual and unique about the Gulfstream portfolio is we have a family now of all brand new airplanes.
And when I say brand new, they're clean sheet. You know that better than anybody what that means, from scratch, all new. Nobody else has that. And that family is compelling. And we're seeing that in our consistent demand.
Great. Thank you.
Our next question comes from George Shapiro from Shapiro Research. Please go ahead with your question.
Yes. Good morning.
Hi, George.
Hi. On the Gulfstream, Phebe, are we seeing the trend for orders continue as strong in the Q2 here?
So we're off to a good start. But undergirding this, you raise an interest undergirding your question is really, I think, more robust demand question. And I think I'll take this opportunity to help us think about demand a little bit more holistically. It's kind of a folly to try to address demand prospectively. It's a little bit easier from a retrospective point of view as long as one is not too myopic about the data.
So what does the data tell us? That the market for Gulfstream airplanes has been good over the last 12 months at a period of ramped up delivery. The book to bill in the quarter was 1.5:one at Gulfstream and almost 1.1:one for the trailing 12 months. This tells me that we're in a period of solid, but not overheated demand. And I see nothing available to me at the moment that suggests a change in that picture.
So that's how you ought to think about, as we go through the year, our expectations about the demand environment.
And then just a quick one on marine. The revenues were somewhat less than I would have thought given the guidance of up 6% for the year and the margin was somewhat better. As we get increased revenues throughout the year, do we have the opportunity that the margin turns out to be higher than your 8.5 percent?
Well, we'll always work toward improved margins. But remember, the revenue is simply a question of timing and mix. And as we move from the Block III to the Block IV, we have accounted for those margin changes. As we see in every by the way, we see this and you know this in every one of our transitions from one block to the other, because we bid down a continuous learning curve and we have a each one of our contracts has the same sort of target profit and we're on a share line. So we always give back some of that goodness appropriately so to the U.
S. Navy. But what does that mean? That means we've got to drive our operating performance relentlessly and continuously and we've done that now for 20 years. So, we will work very hard to consolidate and accelerate our learning on the Block IV.
But at the moment, we're pretty comfortable with the guidance we gave you.
Okay. Thanks very much.
Our next question comes from David Strauss from Barclays. Please go ahead with your question.
Thanks. Good morning. Hi. Phebe, I wanted to try and put a finer point on GDIT. I think publicly it's been said that while 2018 2019 are relatively flat from a revenue standpoint that the 2018 to 2020 kind of growth rate you're still looking for is mid single digits.
Is that correct?
Yes. And I don't think we've given you a whole lot of specificity about 2020, but I tried to set some context to how to think about this growth profile. With that win rate, with the increasing budgets and their post acquisition book to bill, we're in a very good place. So I can I look at this business as long term good growth? And that budget was about $100,000,000 their addressable market budget is about $120,000,000,000 dollars 1,000,000,000 to 5% increase, almost 5% increase.
That's pretty darn impressive. Good opportunity set. Okay. Good opportunity set.
Thanks. As a follow-up, Jason, any quantification you can give on what the drag was in Q1 from the delay on the international side and any sort of idea around timing? I know you're expecting it to reverse this year, but is this more of a second half item that you're looking for? Thanks.
Yes. So the amount that's continued to push to the right, think of it as roughly $1,000,000,000 David, that's what we're talking about. It's lapsed over from last year and continues to push to the right.
And I think it's important to understand that these are negotiations between 2 sovereign powers that are progressing, but they're very, very sensitive as all diplomatic negotiations are. Progress is good, but slow. We do anticipate it resolving this year.
Our next question comes from Cai von Rumohr from Cowen and Company. Please go ahead with your question.
Yes. Thank you so much. So Phebe, I thought I heard you say that the Gulfstream 500 would move into the 2nd production block in the Q2. If that's the case, how come the margins aren't better than the first?
I think second half is what I said. 2nd half, excuse me. Yes. So, I mean that's the inference from us being through that first block, right? And we'll get through that in this quarter and get into the second lot in the second quarter.
So you're right.
Got it. So GDIT, obviously, you're looking for pretty good bookings. It's kind of we look around, there are several very large competitions for competitor programs in the network space, GSMO and NextGen R. How in terms of looking at your expected growth, do you factor those? Because obviously you have other competitors and if you win, things are going to be a lot better and if you lose, they won't be as good as you're projecting.
So how do you factor them?
So if you think about us and you know us and you've known us for years, we are conservative when we look at opportunities. We give healthy discount rates. I think that's a good thing to do for internally for the business and the forecast and guidance that we issue reflects that those discounted rates. So the beauty of a business with 7,000 contracts is that frankly no one is positive. But I'm comfortable that they'll win their fair share.
That said, we've approached this, their pipeline through looking through a conservative prism.
Thank you very much.
Our next question comes from Peter Arment from Baird. Please go ahead with your question.
Yes, thanks. Good morning, Phebe. Phebe, question on combat, I guess, you mentioned some very positive comments regarding the fiscal 2020 funding levels for some of the core platforms. I guess maybe just in the context of longer term growth, how you're thinking about how those programs are shaping up domestically and then what some of the international opportunities that you're pursuing are for that could supplement that growth? Thanks.
Sure. So the U. S. Army is recapitalizing. After the hot wars, they had utilized a lot of their equipment.
And as their budgets drove down rather precipitously, they did not have the resources to go and recapitalize, but they do now and that's exactly what they're doing. So they're modernizing their existing fleet in addition to developing new potential platforms. And we that existing fleet is our programs, right? Stryker and Abrams have seen considerable increases in their budget funding lines because the Army needs those vehicles. The Abrams remains an outstanding tank and the upgrade in the Version 4 is really not your father's Abram.
It is a more capable, more survivable, more lethal system as is Stryker. So we think those 2 core franchise programs for us are in very, very good stead. We work very closely with our Army customers to understand their demands and their requirements and how they think about the war fight. And so we position ourselves in our investment dollars and also thinking about the art of the possible for them on how we can help them meet their objectives. That's certainly true on the franchise programs I've just talked about, but also on new programs.
What is in the art of the possible? What's doable? How fast can you do it? And what's it going to cost you? And the key there is to have the trust of your Army customer who believes that the estimates that you give them are reliable.
So we've had a we are very aligned with our Army customer, know where they're headed and I frankly like everything that I see here. And that's on the big vehicle programs. When I look at our munitions business, our munitions business is growing. I think we grew 10% in the quarter. And we've had a book to bill there that's been very wholesome because as we increase our operational training tempo, our munitions and armaments are increased demand.
So outside the United States, in North America, outside the United States, we see some K. And Canada, where we have decades long presence in both of those countries. Throughout NATO and heavily in Eastern Europe. The world is getting a more dangerous place. And unfortunately, but that is that creates demand for our products.
Our European Land Systems has multiple opportunities throughout the former Soviet border states and Eastern block and domestically and elsewhere. So So threats drive funding and they drive the need for requirements. And unfortunately, we live in a world of increased threat.
Appreciate all the color. Thank you.
Our next question comes from Sheila Kahyaoglu from Jefferies. Please go ahead with your question.
Good morning and thank you for the time everyone. Good quarter.
Thank you.
Just a bigger picture question. I mean revenues were up I think 23% this quarter and profit was sort of flattish. How do we think about that inflection in profit growth in excess of revenue growth and timing of that and any maybe impediments to that that you see?
So let's break the businesses into the 2 distinct factors. Aerospace, I think we've just given you a pretty fulsome and I won't walk you through that. Again, pretty fulsome explanation of the margin compression. And on the defense side, it's really about mix. When you're growing and you've got new contracts coming in, and you've got older contracts closing, you're going to have some mix issues and frankly because all of our defense businesses are growing, we have some of that right now.
So that will resolve continuing throughout the year and then into the future years as we get one thing you can absolutely rely on us for is superb operating performance. We are very good at improving what we Thanks.
Thanks. Appreciate that. And just one follow-up, I think you mentioned $1,000,000,000 contract in Aerospace last quarter. Was that booked?
I'm sorry, where?
You mentioned in aerospace, a $1,000,000,000 contract with an existing corporate customer. Was that booked in the quarter?
Right. Was that booked in the quarter? Yes. Yes. Okay.
Okay. Thank you. Sorry, I couldn't hear you well. Thanks. Thank you.
Our next question comes from Carter Copeland from Melius Research. Please go ahead with your question.
Good morning, Phebe, Jason and Howard.
Hi, Carter. Good morning.
Just two quick ones. 1 on the assumed certification on the 600. Phebe, do you think there's any risk there just given the extra scrutiny and on things like ODA and whatnot given the incident elsewhere in the industry. Just I wonder if you could share any thoughts on that and just help give us some color if there's any risk.
So, both the FAA and us are targeting late June, but they've got a pretty rigorous process. So that may slip a week, a couple of weeks or so. But I think importantly, that does not impact our deliveries, which is really, I think, the key underlying question. We have not seen any new regulations or any new changes in the FAA oversight. So we work very closely with them.
Frankly, they're partners in ensuring that we deliver safe airplanes efficiently. And so they've got an additional workload, but so far haven't really seen much of an impact.
Okay, great. And then just as a follow-up, I noted the comments you made in the prepared remarks around the cost progress on the nacelles and the quality there. And obviously, there's some uncertainty and risk when you took that work on. Is there, in your view, the opportunity to maybe favorably retire some of that risk that you had foreseen as you continue to make progress? And is this indication maybe you're headed in that direction?
So, costs are increasingly under control. The schedules, we de risk a lot of the schedules. We're getting a lot of input from the manufacturing workforce, which will help us optimize our production. And again, we're very, very good manufacturing. So, a lot of at risk is definitely behind us and it's going to get better.
Okay, thanks.
Our next question comes from Seth Seifman from JPMorgan. Please go ahead with your question.
Hey, thanks very much and good morning. So I wanted to follow-up on a question that Peter asked earlier about the combat business. And when we look at the budgets that have come out for Abrams over the past couple of years and what's being requested for 2020. It's kind of in the $2,000,000,000 ish range, which seems like it's probably at least 2x, if not more, what the Abram sales were last year. I mean, should we be expecting Abram sales over the next couple of years to advance to this level?
You should expect them to advance. Think about it this way, for a while that in the period where the Army funding was seriously constrained, that tank plant was producing one tank a month. At the end of this year, we'll be rolling out 30 tanks a month by the end of this year. So that obviously will drive revenue growth. And that backlog increase translates 1 to 1 into revenue.
Right. And then just to follow-up on that one point. When we think about a point that you guys have made consistently in the past is the impact of a mix shift toward domestic production on profitability in combat. Is that primarily an Abrams issue? Because you mentioned some there's growth in Stryker, there's growth on the weapons and munitions side.
Is that primarily an Abrams issue?
So there's 2 things. There's mix between domestic and international. And there's also the mix issue driven by older contracts and newer ones coming on board. So as Abram ramps up, remember we're also doing the mobile protective firepower. We were one of the 2 down select.
And so those are and again, we expect to move down our learning curve. And that will improve the performance over time.
And operator, we'll just take one more question, please.
And our final question comes from Myles Walton from UBS. Please go ahead with your question.
Thanks. Good morning. And Phebe, I'm curious, could you reflect on the certification process of the 500, 600 and how maybe it would influence your thinking of the next new aircraft? How you kind of publicly launch it versus privately launch it? Should we expect kind of timelines from public launch to anticipated EIS to maybe be a little bit shorter as you do more of the certification work behind the curtain?
Myles, if I told you any of that, it is just so proprietary. But listen, you would expect us to have lessons learned from everything we do. These have been extraordinarily successful developmental programs. It's been an extraordinarily successful test program. These airplanes are beating all of their design performance specifications.
So we will continue to work closely with our FAA customer and it will continue to refine our processes going forward. But when we announce any thing or how we announce that's just sensitive.
Okay. And Jason, a clarification, the $1,000,000,000 push to the right you mentioned on the Canadian lab contract for Saudi. I think in the K, you said $1,900,000,000 of unbilled receivables. Curious, can you kind of square those 2 and also the size of the current unbilled receivable? Thanks.
Sure. So the balance between the two is basically the contract work in process that's ongoing on as you'd expect on any contract of this size. So that really is the delta there. And you'll see in the 10 Q we published later today that $1,900,000,000 that we reported at the end of the year is now up to $2,200,000,000
Great. Thanks.
Operator, thank you very much. Prior to the close, I'd like to first thank everybody for joining us today. And then secondarily, as a reminder, we refer you to our website for both the Q1 earnings release and our highlights presentation. If you have any additional questions, I can be reached at 703-876-3117. Thank you very much.
Ladies and gentlemen, with that, we'll close today's conference call. We do thank you for attending. You may now disconnect your lines.
