With that, let me turn things over to AAM's Chairman and CEO, David Dauch.

Thank you, David, and good morning, everyone. Thank you for joining us today to discuss AAM's financial results for the fourth quarter and full-year of 2022. Joining me on the call today are Mike Simonte, AAM's President; and Chris May, AAM's Executive Vice President and Chief Financial Officer. To begin my comments today, I'll review the highlights of our fourth quarter and full-year 2022 financial performance. Next, I'll cover our achievements in 2022 on both electrification and on our legacy business. After Chris covers the details of our financial results, we will open up the call for any questions that you all may have. So let's begin. AAM's fourth quarter operating results, similar to the third quarter, were negatively impacted by industry macro conditions. However, AAM concluded the year with strong cash flow performance for the fourth quarter and the full-year of 2022. We continue to stay focused on managing the factors that are under our control. AAM's fourth quarter 2022 sales were $1.4 billion, and for the full-year, AAM sales were approximately $5.8 billion. From a profitability perspective, AAM's adjusted EBITDA in the fourth quarter was $158 million or 11.3% of sales. For the full-year, AAM's adjusted EBITDA was $747 million or 12.9% of sales. It was simply a challenging year. AAM was negatively impacted by supply chain disruptions including semiconductor availability, which likely impacted global production by over 4 million units in 2022. Combined, these factors drove significant customer production volatility and additionally, we navigated higher input costs throughout the year, including rising utility, labor and material costs. Relative to the first half of the year, the second half of 2022 was a more difficult operating environment for us. That stated, even with these challenges, we found solutions to mitigate a number of these issues and still advance key long-term initiatives on many fronts. I'll cover some of these topics in a few moments. AAM's adjusted earnings per share in the fourth quarter of 2022 was a loss of $0.07 per share. For the full-year, AAM's adjusted EPS was $0.60 per share. AAM's cash flow performance continued to shine. AAM's adjusted free cash flow in the fourth quarter was $99 million, and for the full-year, AAM's adjusted free cash flow was $313 million. This cash flow was deployed in 2022 to support significant debt reduction, our acquisition of Tekfor and investing in electrification to position us for the future. Chris will provide additional information regarding the details of our financial results in a few moments. Let me talk about the business updates and key highlights, which you can see on Slide 4 and Slide 5. We are very pleased to announce that AAM will supply Jupiter Electric Mobility with e-Beam axles for the company's 2.2-ton battery electric light commercial vehicle. Jupiter Electric Mobility is part of India's Jupiter Wagons Limited, which manufactures railcars, commercial and heavy vehicles and marine containers. We note that this is our second e-Beam announcement with our first being EKA Motors. The second announcement is a testament to AAM's ability to combine electric drive technology to a full beam axle configuration, providing optimal performance for electric commercial vehicle applications. Also, we are very happy to share that AAM will supply TracRite Electronic Locking Differentials for a new electric SUV program, providing superior traction for multiple applications and enhancing passenger safety. During CES, many of you experienced this technology firsthand. This vehicle is a derivative of what is out in the market today and the performance of the SUV version should be equally as impressive. AAM is in a great position to provide a full portfolio of products from EV components such as gears and differentials to full electric drive systems. For the full-year 2022, it was certainly an eventful year with many accomplishments. I want to highlight just a few. After much anticipation, we announced and launched one of the most sophisticated and highly engineered electric drive units in the Mercedes-AMG GT 63 performance vehicle. This vehicle is an engineering marvel, and we are excited to support a globally recognized premium performance brand in Mercedes-AMG. In addition, last year, we were awarded multiple contracts with major global OEMs for electric components and drive units. Our strategy to support the full e-Propulsion value chain to OEMs is taking hold and expanding. As a technology leader with a focus on innovation, we are excited to be recognized with three Automotive News PACE Awards in 2022 for our current P3 Electric Drive unit, our collaboration with Mercedes-AMG and for our highly integrated three-in-one drive unit that will launch in the coming years. All the while, we secured our legacy core business with more than $10 billion of lifetime revenue for next-generation full-size truck axle programs from mid-decade to beyond the 2030 calendar year period of time. AAM was also recently named the new axle supplier for GM's next-generation Colorado and Canyon programs, a conquest business win for us. This is a great program for us, and it fits nicely with our mission of securing legacy business as we transition to electric. We anticipate full production ramp yet this year and as 2023 unfolds, we'll see the full effect of that. We also welcome the Tekfor Group to the AAM family. Their technical expertise in improving friction and surface treatment is extremely pertinent for e-Propulsion applications as well as expanding customer and geographic diversification. Furthermore, we received a number of additional recognitions, including being named one of Forbes Best Large Employers, not only in 2022, but also already here in 2023. Additionally, Newsweek recognized AAM as one of America's most responsible companies. Now let's talk about our long-term strategy. As I said before, our strategy is very straightforward. We will continue to secure our legacy core business, optimize our operations and drive EBITDA and cash flow generation. As volumes return, this business model is designed to yield handsome conversion. At the same time, we will continue to invest in electrification and solidify our position as a global leader in e-Propulsion systems, providing OEMs with cost-effective, high-value solutions. On the electrification front, we recently hosted an investor event and displayed our electric drive systems and components at CES, where we demonstrated our industry-leading electric drive technology. It is great to see many investors experience our engineering firsthand while having the opportunity to drive our electrification demonstration vehicles across multiple vehicle segments. What differentiates AAM is our platform technology that can accommodate the electric propulsion needs across light vehicle segments, ranging from small cars to light commercial vehicle applications. The flexibility and modularity provides legacy and start-up OEMs with superior optionality from components, gearboxes, motors, power electronics to full systems and e-Beam axles. We hope that we clearly conveyed that message to you at CES. Before I turn it over to Chris, let me reiterate our three-year new business backlog that we shared during our Technology Day and discuss when we also discuss our 2023 full-year financial outlook that was included in our press release this morning. AAM expects our gross new business backlog covering a three-year period of 2023 to 2025 to be approximately $725 million. We expect the launch cadence of this backlog to be $350 million in 2023, $225 million in 2024 and $150 million in 2025. Our backlog factors in the impact of updated customer launch timing, our latest customer volume expectations and does not include replacement business, only new and incremental business. From a launch standpoint, we have 17 major launches here in 2023, which should drive growth over the next several years. For the backlog breakdown, please refer to Slide 6 in our presentation package, 40% stems from electrification compared to 35% last year. Our approach to electrification is gaining traction in our book of business. And currently, as we've communicated before, we're quoting approximately $1.5 billion of new and incremental business with over 75% of the quotes that we are working on coming from electrification programs. Let's talk about 2023 from an end market perspective. We forecast production at approximately 14.5 million to 15.1 million units for our primary North American market. This represents anywhere between a 1% to a 6% increase over last year. Because of the industry's recent production trends stemming from multiple factors, including the supply chain challenges and macro environment I mentioned earlier, we remain cautious about the build environment in 2023 at this time. As such, Slide 7 illustrates AAM's 2023 financial outlook. AAM is targeting sales of $5.95 billion to $6.25 billion, adjusted EBITDA of approximately $725 million to $800 million, adjusted free cash flow of approximately $225 million to $300 million, which assumes capital spending in the range of 3.5% to 4% of sales. In the near-term, we will remain focused on mitigating inflation, optimizing our business and addressing cost recoveries. Furthermore, we'll remain aggressive in our plans to position the company for future margin expansion. This includes our focus on plant capacity and utilization, variable and structural cost improvements and further reducing the capital intensity of our business. These initiatives will have a positive impact on our business over the next several years. And as we stated at CES, our goal is to continue to be a top-tier margin performer and cash flow generator. In the longer term, we will continue to focus on securing our core business, generating strong free cash flow, strengthening our balance sheet, advancing our electrification portfolio and positioning AAM for profitable growth, especially in the area of electrification. I'm very excited about what lies ahead for AAM, and that concludes my remarks today. Let me now turn the call over to our Executive Vice President and Chief Financial Officer, Chris May. Chris?

Thank you, David, and good morning, everyone. I will cover the financial details of our fourth quarter and full-year 2022 with you today. I will also refer to the earnings slide deck as part of my prepared comments. So let's go ahead and begin with sales. In the fourth quarter of 2022, AAM sales were $1.39 billion compared to $1.24 billion in the fourth quarter of 2021. Slide 10 shows a walk of fourth quarter 2021 sales to fourth quarter 2022 sales. In the quarter, we experienced a lower negative impact from semiconductor and supply chain challenges, which we estimate at approximately $21 million. Positive volume, mix and other was $128 million. The Tekfor acquisition contributed $84 million to sales. And lastly, metal market pass-throughs and FX lowered net sales by approximately $68 million, with metal and FX both lower. Although sales were up year-over-year, we note that supply chain volatility continued sequentially from the third quarter, resulting in frequent changes to schedules. For the full-year of 2022, AAM sales were $5.8 billion compared to $5.16 billion for the full-year of 2021. The primary drivers of this increase were the Tekfor acquisition, which occurred on June 1 and accounted for approximately $200 million in sales and additional volume and mix throughout the year. Now let's move on to profitability. Gross profit was $167.2 million in the fourth quarter of 2022 compared to $140 million in the fourth quarter of 2021. Adjusted EBITDA was $157.7 in the fourth quarter of 2022 versus $164.6 last year. You can see the year-over-year walk down of adjusted EBITDA on Slide 11. In the quarter, higher sales due to a lower impact of semiconductor availability and overall volume and mix and other added a net $39 million of adjusted EBITDA versus the prior year. Fourth quarter material, freight and utility inflation, net of customer recoveries was an $8 million headwind. The net headwind for all of 2022 was $60 million and in line with previous estimates. R&D was higher by approximately $18 million to support product launches and our electrification portfolio. You may recall, last year, we had the benefit of a large customer ED&D reimbursement that accounts for most of this year-over-year difference. And lastly, Tekfor added approximately $5 million in adjusted EBITDA. For the full-year of 2022, AAM's adjusted EBITDA was $747.3 million and adjusted EBITDA margin was 12.9% of sales. Let me now cover SG&A. SG&A expense, including R&D, in the fourth quarter of 2022, was $88.5 million, or 6.4% of sales. This compares to $77.5 million, or 6.3% of sales in the fourth quarter of 2021. AAM's R&D spending in the fourth quarter of 2022 was approximately $39 million. As we head into 2023, we will continue to focus on controlling our SG&A costs and investing in our electric drive technology, capitalizing on the growing number of electrification opportunities that are before us. And we expect R&D to increase in 2023 and be closer to the $40 million per quarter on average, although timing can be lumpy. The good news here is we continue to see multiple new opportunities driving the spend. Let's move on to interest and taxes. Net interest expense was $36.9 million in the fourth quarter of 2022 compared to $41.8 million in the fourth quarter of 2021. We continue to benefit from our debt reduction actions. In the fourth quarter of 2022, we reported income tax expense of $4.1 million compared to a benefit of $2.3 million in the fourth quarter of 2021. As we head into 2023, we expect our adjusted effective tax rate to be approximately 20% to 25%. Taking all these sales and cost drivers into account, our GAAP net income was $13.9 million or $0.11 per share in the fourth quarter of 2022 compared to a net loss of $46.3 million, or a loss of $0.41 per share in the fourth quarter of 2021. Adjusted earnings per share, which excludes the impact of items noted in our earnings press release, was a loss of $0.07 per share in the fourth quarter of 2022 compared to a loss of $0.09 per share in the fourth quarter of 2021. For the full-year of 2022, AAM's adjusted earnings per share was $0.60 versus $0.93 in 2021. Let's now move on to cash flow and the balance sheet. Net cash provided by operating activities for the fourth quarter of 2022 was $148.5 million. Capital expenditures net of proceeds from the sale of property, plant and equipment for the fourth quarter of 2022 were $53.1 million. Cash payments for restructuring and acquisition-related activity for the fourth quarter of 2022 were $6.6 million. The net cash inflow related to the Malvern Fire was $3 million in the quarter. Reflecting the impact of these activities, AAM generated adjusted free cash flow of $99 million in the fourth quarter of 2022. For the full-year of 2022, AAM generated adjusted free cash flow of $313 million compared to $423 million in 2021. As a team, we remain focused on free cash flow conversion, including managing CapEx effectiveness and efficiency and reducing cash restructuring payments. From a debt leverage perspective, we ended the year with a net debt of $2.4 billion and LTM adjusted EBITDA of $747.3 million, calculating a net leverage ratio of 3.2 times at December 31. This is down from a 3.3 times leverage ratio at September 30, 2022. In 2022, we lowered our gross debt by over $150 million, including $50 million inside of the fourth quarter. We will continue to utilize the free cash flow generating power of AAM to strengthen the balance sheet by reducing our debt. In addition, we refinanced our Term Loan B in the fourth quarter and now have no significant maturities until 2026. AAM ended 2022 with total available liquidity of approximately $1.4 billion consisting of available cash and borrowing capacity on AAM’s global credit facilities. So before we move on to the Q&A portion of the call, let me provide some thoughts on our 2023 financial outlook. In our earnings slide deck, we have included walks from 2022 actual results to our 2023 financial targets and you can find those starting on Slide 13. For sales, we are targeting a range of $5.95 billion to $6.25 billion for 2023. This sales target is based upon a North America production of 14.5 to 15.1 million units and select assumptions for our key programs. New business backlog launches of approximately $350 million and attrition of approximately 200 million. There is continued uncertainty in 2023, as David mentioned. Although supply chain issues appear to be stabilizing relative to last year, the volatility that we experienced in the second half of 2022 looks to continue in the near-term of 2023. We remain cautiously optimistic that the operating environment will improve throughout the year. From an EBITDA perspective, we are expecting adjusted EBITDA in the range of $725 million to $800 million. Let me provide some color on the key elements of our year-over-year EBITDA walk on Page 14. First, we expect to convert our recurring year-over-year product volume and mix increases at approximately 25% variable profit. Second, the incremental portion attributable to the Tekfor acquisition principally represents five additional months of profit contribution in 2023 versus 2022. Keep in mind, since this is the annualization of an acquisition, the additional profit contribution is realized at a full cost margin profile and not variable profit rates. Third, our R&D spending will increase year-over-year as we invest in our future and support electrification projects that are in various stages of launch and development. Four, we anticipate some higher costs related to inflation this year and our goal is to successfully negotiate with our OEM customers for recoveries. And lastly, AAM expects to deliver operational productivity to mitigate some of these inflationary costs and efficiency pressures we are experiencing inside of our own operations. You can see a continued year-over-year performance on our walk of a net positive $10 million. On Page 15, from an adjusted free cash flow perspective, we are targeting approximately $225 million to $300 million in 2023. The main factors driving our cash flow changes are as follows. We have capital expenditures as we are coming up on some key launches and investments such as automation and electrification business. However, our CapEx to sales ratio is still very low by our historical measures, as we are targeting a CapEx as a percent of sales of approximately 3.5% to 4%. We also are expecting higher cash interest and taxes and we do see opportunity to improve working capital in particular related to inventory. And lastly, while not included in our adjusted free cash flow figures, we estimate our restructuring payments, primarily related to the integration of our recent acquisitions to be in the range of $20 million to $30 million for 2023. This continues a multi-year trend for reduction of these type of expenditures. We expect to use the free cash flow generated in 2023 to continue to reduce debt, further solidify our position in electrification and take advantage of select market opportunities to support growth should they arise. As it relates to cadence for the year, we anticipate the first quarter to experience the lowest sales per production day and an overweight timing of price reductions. We also expect to realize a disproportionate impact from cost headwinds similar to what we experienced last year. These costs typically include a timing aspect where recoveries occur in the following quarters. As the year progresses, we forecast these net costs to improve on a quarter-over-quarter basis. In addition, our new business backlog timing increases throughout the year. And lastly, we would expect a more stable operating environment as the year goes along. So in conclusion, 2022 was a tough year driven by production choppiness, supply chain inconsistencies and input cost challenges, all ultimately impacting our cost structure. That said, AAM will continue to focus on what we can control, including driving optimization, successfully negotiating customer recoveries, integrating the Tekfor acquisition, executing on our capital allocation plan and developing class-leading electrification technology. We are actively positioning AAM to be the electric propulsion supplier of choice and you can see evidence of that from our growing backlog and electrification mix. So as costs stabilize, volumes return and the realization of cost optimization improvements outlined by David earlier, AAM should generate nice future EBITDA conversion translating to continued robust free cash flow generation. Thank you for your time and participation on the call today. I'm going to stop here and turn the call back over to David, so we can start Q&A. David?

Thank you, Chris and David. We have reserved some time to take questions. I would ask that you please limit your questions to no more than two. So at this time, please feel free to proceed with any questions you may have.

Operator instructions were provided. Our first question today comes from John Murphy from Bank of America. Please go ahead with your question.

Good morning, guys.

Good morning, John.

Good morning, John.

Hey. First question on the step-up in R&D. I mean we saw some of the fruits of that in its early stages in some of the stuff — the products you showed us out in Vegas, packaging around the inverter and the electric motor were very interesting and fairly unique. But I'm just curious, as we think about this R&D step up, how much of it is program-based for products that are in the bidding process and you may have won versus product development to really go and pitch your EV technology to your customers? I'm just trying to understand how much of this is structural going forward or how much is kind of a step-up here in the short run as well?

John, this is David. I would say a lot of our initial spending right now is more on the platform-based technology to get our portfolio in a position that we can actively market to our customers. Clearly, there will be some program-based spending as we win new business going forward. But the majority is platform-based to put the product line in place. And once that product line is in place, then we'll expect that to scale down. But hopefully, some of the program wins may require us to spend some additional electrification engineering resources or R&D as we book new business.

Okay. And then just sort of a housekeeping or two quick housekeeping, Chris. The volatility in schedules and the disruption, can you just remind us what that cost you in 2022? What you expect in 2023? And then also, when we think about gross versus net on net new business or new business, it seems like there's a big attrition this year of $200 million. How should we think about attrition against that gross business bookings over time?

Yes, John, in terms of your first question associated with the efficiency impacts. If you think about — if you look at our — the walks that we provided throughout the course of the year, we have a call in there called performance and other. And for example, in the fourth quarter, it's minus $13 million. The vast majority of that would be associated with the impact of some of that volatility. So you saw that both in the third quarter, which was a little lighter than that. You saw some further onset in the fourth quarter that we articulated. The variances that you saw in the first half of 2022, I wouldn't really articulate those more as efficiency related to the volatility because those were comparing to periods, I would call them, an almost near-COVID shutdown type of activity at the beginning of 2021. But those variances that you see on our walks in the back half of the year would be by and large indicative of what we're experiencing through our operations. The second question — does that answer your question?

Yes. So I mean, so you're talking about something that's in the $20 million, $30 million range, I mean if you kind of put that together?

Yes, over the back half, that's what we experienced, correct, that's reasonable.

And do you expect that to continue into 2023 at the same rate eventually if the world stabilizes, that would then go away? Is that a fair statement?

Yes, that's a fair statement. Correct.

Okay.

And I think your second question then was associated with attrition. We have $200 million of attrition on our year-over-year sales walk that relates to some programs in China and also some in North America. We have historically said the impact associated with that was between $100 million to $200 million this year, is at the higher end of the range. I would think more closer towards the midpoint kind of in the subsequent years.

Okay. Great. Thank you very much, guys.

Yes. Thanks, John.

Thanks, John.

Our next question today comes from Dan Levy from Barclays. Please go ahead with your question.

Hi. Good morning, and thank you for taking the question.

Good morning, Dan.

Good morning. Wondering if you could just talk a bit to the mix trend? Obviously, T1, if you look at some of the third-party schedules, I think that's forecasting them to be down year-over-year. Can you just talk about the impact of mix on margins?

Yes. So from a broad perspective, as associated with mix as it relates to — if you think about our two largest programs, T1, RAM is obviously a large program. I'll come back to both of those in a minute. The rest of production, I would expect to continue as volumes come back that to increase on the rest of the business, so that will start to increase its proportional sales mix of our overall business. RAM, probably very similar year-over-year. So obviously, you can compute how the mix would impact from that. And on the T1 perspective, I believe some estimates — third-party estimates yesterday were just updated to be a little bit more elevated. I would think about that sort of the lower end of our sales range. We're a little more bullish on that platform. Our customers are a little more bullish on that platform, we believe. So think of our midpoint of the range, maybe about 5% higher than current IHS estimates, and we're probably a little higher than that at the high end of our range. But again, we're a little more bullish on that. But you'll see the rest of our book of business continue to grow as part of that mix.

Great. Thank you. And then the second question is on your electrification backlog. So your narrative on EV is that you have a variety of ways to win between subcomponents to full three-in-one system. Could you maybe break down of that 40% of the backlog that is EV? Is there a rough idea of the mix on subcomponents, full drive units, some of the casing and the rough content per vehicle that's implied there?

Yes. Dan, this is Chris again. Yes, the mix, think about it slightly more than half is associated on the drive units, the other — the remainder then would be on the component side. And then from a content per vehicle perspective, obviously, on the drive units, as you've heard us articulate our content per vehicle is very significant associated with those. Think of up to $2,500-plus. And then on the component side, depending on the vehicle, depending on the component supply, we could be up to $500 per vehicle.

Okay, great. Thank you.

Yep.

Thanks, Dan.

Our next question comes from Emmanuel Rosner from Deutsche Bank. Please go ahead with your question.

Thank you very much. Good morning.

Good morning, Emmanuel.

First question on the Tekfor acquisition. It seems based on your 2023 walk, you're expecting maybe a margin contribution sort of like the low double-digits based on the guidance. Can you just remind us if this is the right margin profile for the business going forward or if there's more incremental opportunity for improvement?

Yes. So if you think about — they came on mid-year, June 1, 2022. And if you look at the full-year performance, the Tekfor had for us and contributed in 2022 from an EBITDA perspective, it was just a little bit north of 7%. And you may recall, going into this transaction, we saw a great opportunity to expand some of our diversification in customers, but also a great synergy opportunity. So the incrementals you see coming on line for 2023, you're sort of more than 10% to 12.5% range. So you're accomplishing a couple of elements that you're bringing on the full cost business for the first five months, plus you're starting to see some of those synergies start to kick in, in 2023. So that implies sort of $5 million to $10 million range of synergies coming online because you'll get a holistic lift to your margins. I would expect synergies to continue to grow after this period as well. And then obviously, once we transition past the full-year 2023, their change in revenues will be on a variable profit basis.

Yes. That makes sense. I wanted to ask you about non-material cost inflation. I think you had previously indicated you expect some of this inflation to be sticking around for the year. I don't really see it as a sort of a major factor in the walk. Is this not a headwind for this year? Or do you anticipate offsetting these cost increases with productivity?

Yes. No, it continues to be a headwind in particular areas such as labor and some other costs that we incur. It's included in our productivity, inflation and other common net column. If you think about in 2022, our net residual after customer recoveries for the bulk of this type of inflation was about $60 million. We also had some labor inflation on top of that. Our expectation is that on a net basis it is lower than that, lower than half of that here in 2023 versus 2022. But again, customer recoveries and productivity initiatives will help us offset a lot.

Okay. And just very finally, if I can squeeze one more.

Sure.

So I guess in terms of overall message, right? So your industry conditions are still fairly choppy, and that sort of continues to put some pressure on margin. What sort of — what do you need to see to get back towards sort of like a path of stable margins or margin expansion? Is it just — is it mostly around the volatility of schedules? Is it sort of like additional industry volume growth? I guess what would be needed for that?

Yes. Emmanuel, this is David. I mean, clearly, the first thing is we just see stabilization in our business, right? We were dealing with so much uncertainty and volatility in our production schedules. So first thing is stabilization of the production schedules. Clearly, any growth, as the market starts to recover and rebuild some of the inventory, I don't think the inventory will ever go back to historical levels, but incremental growth will be positive for us. And then we also need to see stabilization of the workforce from a labor standpoint. And we're not waiting around for that. We're making investments in automation and other things to take those things into our own control. But the biggest thing would be stabilization across the board.

This is Chris. That's from the labor perspective. Your question even more broadly as it relates to margins. Obviously, volume drives a lot of that stabilizing or reducing, even metal market reimbursements, obviously, inflation that we just talked about. And ultimately, as David mentioned in some of his prepared remarks, continued pressure on some of our fixed cost and capacity utilization increases will drive margin as well.

Thank you very much.

Yes.

Our next question comes from James Picariello from BNP Paribas. Please go ahead with your question.

Hi. Good morning, guys.

Good morning, James.

Just as a follow-on to the last question, just taking a step back and looking at by segment, thinking about most of nearly all of the R&D investments taking place in the Driveline segment, what is really — what are the driving forces that challenge the metal forming segment? And does this fourth quarter represent the bottom, right? I mean because we've seen some pretty notable sequential refines from an EBITDA perspective. Does the fourth quarter mark the bottom for metal forming? And if not, just time line on that? And when does this get better? When does this get better for this segment?

Yes, James, this is David. Yes, we do expect the fourth quarter this past year to be the bottom. Clearly, the big issue we're battling is labor availability in our metal forming area. We're working hard to stabilize that and also bring automation into those factories. But clearly, it's a heavy fixed cost business. We need volume running across it. We clearly run a lot better when we have the incremental volume going across that. At the same time with schedule volatility, you can't lay off people. So therefore, there's an incremental cost; the same 10 new people that we're bringing in don't have that experience level and we're incurring some incremental overtime and scrap that we historically haven't endured. But we do think the fourth quarter was the bottom of the metal form performance. We'll start seeing some improvement quarter-to-quarter going forward.

And James, this is Chris. One other point I would add. You mentioned that the R&D is disproportionate on the Driveline segment of our business. What I would tell you, at least from an inflation standpoint perspective, utilities, costs and metal market impacts are overweight to the metal forming side of the business. So you see some of that on their margin pressure, and you saw that sort of play out through the course of 2022, as those cost elements moved around, and you saw inflation for utility, in particular in Europe, which is where they have a large concentration of businesses.

Got it. Understood. That's helpful. And then just one on interest expense. What's driving the higher interest expense? Is it — was it the refi that took place in the fourth quarter just carrying a higher interest rate? Or should we assume you're carrying some more short-term related debt on the balance sheet?

Yes. I would tell you, it's a composition of three elements. First, we actually are — although it's hard to see, receiving some benefits from our continued debt pay down. But the two elements driving the net cost up would be, one, when we refinanced our Term Loan B, the spread on that was up 125 basis points versus the Term Loan B that was originally put back in place in 2017. And secondly, as you know, this is a variable rate debt instrument. So it's effectively SOFR plus the spread and SOFR is now, what, three to four times what it was a year ago. So that's really driving a piece of that. A good chunk of this we have hedged, but holistically, the rates are up on the variable debt instrument.

Understood. Thank you.

And ladies and gentlemen, our final question today will come from Ryan Brinkman from JPMorgan. Please go ahead with your question.

Hi. Thanks for taking my question.

Good morning, Ryan.

How should we think about R&D and CapEx trending as a percentage of sales beyond 2023? And as we drill down to the impact on like EBITDA or FCF over a multi-year period, do you expect that the earnings and cash flow headwind from higher electrification spending is more of a like multi-year timing issue given that spending is taking place in advance of product launches and that the contribution margin when these products do launch will offset the higher cost over time? Or I guess said differently, while dilutive initially is the pivot toward electrification accretive, dilutive or neutral to EBITDA margin and free cash conversion over the medium and long-term?

Yes. From a cash perspective, as you point out, and David mentioned in one of the previous questions, our R&D spend would be elevated as we're building out our product portfolio. That would then decline and then you have some potential program specific R&D as you step into launches. But we would see some opportunity over an extended period of time, as you mentioned, in the future, we would expect this then to at some point pivot and decline down. From a CapEx perspective, we're coming off of 2022, which was, I think, the lowest percent of sales for CapEx in the company's history. Our guide here this year, which continues to have program launches, also electrification element of it, still quite low by our historical standards to 3.5% to 4%. But our commentary around this has been to try to maintain our CapEx on the near and mid-term at less than 5% of sales. We have been very focused on capital efficiency and effectiveness. And even as we're pivoting into electrification, continuing to maintain a good, healthy control and balance over our CapEx spend is a top priority for the company. Now where could you see a different solution is when you win a significant amount of new and incremental business inside of the company where you would have to spend some extra dollars, we think that would be a great investment to make.

Okay. Thank you very much.

Yep.

Great. Thank you, Ryan. And we want to thank all of you who have participated on this call and appreciate your interest in AAM. We certainly look forward to talking with you in the future.

Ladies and gentlemen, with that, we'll conclude today's conference call and presentation. We do thank you for joining. You may now disconnect your lines.
