GM International delivered Q4 EBIT-adjusted of $300 million, flat year-over-year, as the team did an impressive job executing in a volatile environment. This included $200 million of equity income in China, down slightly year-over-year due to lower volume and pricing pressure, partially offset by cost actions. EBIT-adjusted in GM International, excluding China equity income was a $100 million, up slightly year-over-year and profitable in all four quarters. These consistent results were driven by favorable pricing and volume, partially offset by mix and commodity costs. I want to take a moment and recognize the transformation this team has executed over the last few years, achieving over $2 billion of EBIT-adjusted improvements since 2018. This was done by exiting unprofitable markets, strengthening the portfolio, leveraging our strong brands to significantly improve pricing and mix, all while simultaneously driving down costs. They've done amazing work as a team and they should be lauded for that. GM Financial delivered strong results with Q4 EBIT-adjusted of $800 million, down $400 million year-over-year, primarily due to lower net lease vehicle income and higher cost of funds, partially offset by growth in the retail and commercial loan portfolios. Used vehicle prices have declined but continue to run above the contract residual value with a Q4 off lease return rate below 10%. Overall portfolio credit metrics continue to be strong in part due to a predominantly prime credit mix with net charge-offs up slightly due to moderation and credit performance, but still running below pre-pandemic levels. GM Financial paid dividends of $1.7 billion in 2022, and we expect similar dividends in 2023. Corporate expenses were $400 million in the quarter, flat year-over-year as we continue to invest in growth initiatives and drive productivity. Cruise expenses were $500 million in the quarter, up $200 million year-over-year, driven mainly by modifications to equity awards resulting in an accounting change in compensation expense. Our optimism continues to grow based on the great progress Cruise made in 2022, and their plans for rapid scaling and operationalizing of the business will result in a modest increase in cost during 2023. Let's now look towards 2023 for GM overall, which I know is a key focal point for everyone. While the environment remains uncertain, at a high level I'm pleased to report that when you exclude the impacts of lower pension income and GM Financial contribution, we expect to drive consistently strong core auto operating performance in 2023. This continues the trend we saw in 2022 and highlights the strong execution throughout the organization. Our plan is to continue to prioritize growth initiatives such as Cruise and BrightDrop, while investing to accelerate our transition to EVs to take advantage of our vertical integration and local sourcing strategies. Assuming a 15 million total industry volume and under current conditions, we expect EBIT-adjusted in the $10.5 billion to $12.5 billion range, EPS diluted-adjusted in the $6 to $7 per share range, and adjusted automotive free cash flow in the $5 billion to $7 billion range. At GM Financial the strong credit performance in historically high used vehicle prices resulted in extraordinary results over the last two years. For 2023, we expect earnings to normalize in the mid $2 billion range. We expect volume and mix combined to be a slight tailwind with volumes up 5% to 10% year-over-year, and mix partially offsetting as we continue to increase production in the sedan, small SUV and crossover segments along with GM International volume growth. Regarding North America pricing, while we anticipate incentives will increase from the record low levels we saw in 2022, we expect this headwind to be partially offset by realizing the full year benefit of MSRP increases on many model year 2023 vehicles, particularly full-sized SUVs and trucks, as well as pricing we expect to achieve on our new launches in 2023. We're also anticipating pricing actions outside North America primarily to help offset FX headwinds. Overall, we see commodities and logistics costs as a slight tailwind. Our longer-term steel and logistics contracts, which help protect us from higher market costs over the last two years, renewed at higher rates in the second half of last year. This combined with the strategic initiatives to locally source battery raw materials is expected to largely offset the tailwind we're seeing from lower raw material prices on our spot and indexed exposures. The $1 billion lower pension income impacts our fixed costs. This non-cash item does not impact our core auto operating results, but will be a headwind when comparing year-over-year in 2023. As Mary mentioned, we are very focused on keeping automotive controllable fixed costs in check despite our growth initiatives, which is why we are announcing a cost reduction program to take out $2 billion of costs over the next two years. Included in our guidance is the expectation to achieve 30% to 50% of that in 2023 and the remainder in 2024. This initiative is the result of several factors and demonstrates our continued commitment to closely manage our operations through this transformation and achieve North American margins in the 8% to 10% range through 2025. We expect capital spend to be in the $11 billion to $13 billion range inclusive of $1 billion invested in our Ultium Cells JV. We continue to shift resources to EVs with around 75% of our product specific capital dedicated to EVs and AVs. Even with the increase in capital spending, we expect our adjusted free cash flow to remain strong in 2023. As we said back in November, we expect that clean energy tax credits will be a material tailwind for GM over time because of the work we've been doing on vertically integrating the supply chain. For 2023, we anticipate at least $300 million in EBIT-adjusted benefit and expect this tailwind to increase significantly over the next few years as our cell production ramps and our North America focused supply chain comes fully into place. We're closely monitoring the dynamic macro environment as well as customer demand to make sure we're appropriately matching supply with demand. We will take quick and decisive actions on both the supply and the cost side to actively manage the business. What gives us confidence in our 2023 and long-term objectives is the work we've already done to position ourselves for success, repeatedly executing on our commitments and our ability to manage through a very challenging and dynamic environment. With a compelling EV and ICE product portfolio, long-term supply chain commitments, extraordinary manufacturing capabilities, a strong balance sheet, and our amazing team, I'm confident we'll continue to enhance the customer experience and deliver compelling growth on both the top and the bottom line.
