Thank you, Mary. I appreciate you all joining us this morning. Our robust vehicle portfolio combined with our continued disciplined market strategy has once again delivered solid financial results. Our Q1 US sales growth outpaced every other major automaker. US deliveries were up 17% year-over-year and our market share grew to 17.2% marking a nearly two point improvement from the prior year, all while maintaining incentives around 300 basis points below the industry average. We ended the quarter with ICE US dealer inventory of 49 days, down from 53 days at the end of Q4. Inventory is turning quickly and nearly 90% of the inventory at quarter end was comprised of model year 2025. As we all know, we are witnessing a significant shift in policy into the new administration and we are encouraged by the President's recent actions to strengthen the auto industry. As Mary outlined, we have already implemented several no regret strategies to mitigate some of the impact with additional measures being evaluated. Adapting to this dynamic environment will take some time, but we remain confident in our ability to respond effectively and offset at least 30% of our exposure. We believe our product portfolio and continued strong demand for our vehicles positions us ahead of the competition during this period of transition. So let me begin by summarizing our Q1 results. Total company revenue for the quarter was $44 billion up 2% year-over-year with wholesales also up 2%. We achieved $3.5 billion in EBIT adjusted, 7.9% EBIT adjusted margins and $2.7 billion or $2.78 in EPS diluted adjusted. Our EBIT adjusted was down slightly from last year's Q1 performance. So let me walk you through some of the key items on the bridge. Pricing was up around $900 million year-over-year, demonstrating our ongoing disciplined market strategy as well as continued strong demand for our products, like the new midsize SUV family, the Chevrolet Traverse, GMC Acadia and Buick Enclave, as well as our compact SUVs, the Chevy Equinox and GMC Terrain. Let's turn to volume and mix. Wholesale volumes of light duty full size trucks declined year-over-year largely due to a few weeks of scheduled downtime at our full size truck plants for upgrades along with the effects of the supplier fire that Mary mentioned earlier. However, this was more than offset by the Chevy Trax and Buick Envista delivering exceptional year-over-year growth propelling us to a leading position in the US small SUV segment. In EVs, we achieved over 90% year-over-year growth securing the number two position in the US. Model likes the Equinox EV are gaining meaningful traction with mainstream customers. Meanwhile, Cadillac continues its momentum with EVs now accounting for 20% of its US sales. FX was a headwind of around $300 million in the quarter, primarily attributable to weakness in the Mexican peso. Fixed costs were up $400 million year-over-year due to higher depreciation and amortization, ongoing warranty pressure and higher labor costs partially offset by the reductions at Cruise. Relative to warranty costs, we face persistent inflation challenges and are also taking voluntary measures to address the 6.2 liter L87 engine supplier quality issues in some models year 2021 to 2024 vehicles. The good news is that dealers have already begun applying the remedy to vehicles in their possession. It's the right thing to do for our customers. Despite around $500 million of incremental expenses for the L87 in the second quarter, we expect warranty to still be a slight year-over-year tailwind in 2025. We are focused on maintaining our cost discipline. Comparisons become easier as the year progresses, and we expect fixed costs including cruise, but excluding depreciation and amortization to be roughly flat year-over-year in 2025. Now let's move to North America. Notwithstanding higher wholesales quarter over quarter, US dealer inventories were down in part due to a meaningful step up in the SAAR throughout the quarter. The industry undoubtedly benefited from some pull ahead demand from customers purchasing vehicles ahead of potential tariff impacts, particularly in March. But the strong demand has continued into April, where we've seen US deliveries up around 20% versus last year. Q1 margin was 8.8%, well within our 8% to 10% target range despite the additions of the expenses that were formerly at Cruise. With respect to our international business, GM International EBIT adjusted excluding China equity income was breakeven in a seasonally low quarter influenced in part by this year's timing of holidays in The Middle East. China equity income reached nearly $50 million. The team in China, including our JV partner, have made significant strides in reducing inventory and costs while also focusing on enhancing the competitiveness of our products. Their efforts are yielding results as evidenced by a third consecutive quarter of sequential market share growth. Notably sales of our new energy vehicles increased 53% year-over-year. GM Financial also performed well with Q1 EBT adjusted of almost $700 million in line with last year. Higher provision expense from increased loan origination volume was partially offset by higher net financing revenue and leased vehicle income. GM Financial continues its proven track record of profitability and consistent capital return to GM with another $350 million dividend paid during the quarter. Now let me spend a few minutes on tariffs. Beginning in early April, a 25% vehicle import tariff was imposed. For vehicles that are USMCA compliant, which all of our North American produced vehicles are, the US content is not subject to the tariff once necessary administrative processes are implemented in the coming weeks. Since the election, our manufacturing and supply chain teams have been focused on developing strategies to help mitigate the impact of potential tariffs. These strategies are now actively being put into action. Mary mentioned a few of these examples in her remarks. We'll take additional mitigation measures, including cost reduction targets where it makes sense to do so. We're reviewing the cost initiatives that were implemented during COVID, but we want to ensure that we don't cut too deep. The environment is very different today than COVID as demand remains quite strong. They've also announced tariffs on imported parts. While we source parts globally, our guiding principle is to buy where we build. The US is GM's primary location for sourcing parts supply for US assembly, comprising well over half of its annual parts expenditure. Steel and aluminum are largely sourced local to production. We have a proven track record of working collaboratively with our suppliers to navigate industry challenges and we anticipate that this occasion as we work to increase US sourcing further will be no different. By working together, guided by transparency and trust, we are carefully evaluating the actions we can take with our suppliers to help mitigate the impact on their business. One of Tuesday's presidential actions will provide a tariff offset based on the more than 1.5 million vehicles we build in the US each year. This will help mitigate a substantial portion of tariffs on parts going into those vehicles and help avoid added costs on US vehicle production. This offset program supplements, but does not replace continued preferential treatment for USMCA compliant parts. The other action will ensure that tariffs on parts don't stack on top of each other. We believe both of these are smart policies that help encourage companies to do more in the US while also ensuring satisfactory return on invested capital. Now let's move to our 2025 guidance. Based on Q1 results, our underlying business trends remain strong and would have kept us on track with the initial guidance that was given on the Q4 earnings call with better pricing offsetting warranty and FX headwinds. Post clarity from the presidential actions of Tuesday, we are expecting a $4 billion to $5 billion impact from tariffs. This includes about $2 billion coming from vehicles we import from Korea as well as tariffs on vehicle imports from Mexico and Canada in addition to indirect material imports. Based on the current commercial environment, our updated guidance assumes we can offset at least 30% of this headwind via self-help initiatives. This results in EBIT adjusted in the $10 billion to $12.5 billion range, EPS diluted adjusted in the $8.25 to $10 per share range and adjusted automotive free cash flow in the $7.5 billion to $10 billion range. Pricing was strong in the first quarter as well as during in the month of April. We now expect pricing to be relatively consistent for the remainder of the year. As a result, we expect North American pricing to be up 0.5% to 1% year-over-year versus our prior guidance of being down 1% to 1.5%. On the EV side, we have a strong portfolio and saw significant year-over-year growth in both volume and US shared in the first quarter. We maintained our number two position in the US market, notwithstanding the US EV industry moderation from the fourth quarter last year to the first quarter this year. Going forward, we will continue to remain disciplined and manage EV production in line with demand. Inventory levels for EVs remained reasonable at 78 days at quarter end and our EV incentives continue to be well below the industry average. We are continuing our momentum on EV profitability improvement. In the first quarter, nearly 50% of our entries were variable profit positive. The portfolio was near breakeven on variable profit, primarily due to a mix of production during the quarter. Going forward, we expect to continue to make progress on our EBIT improvement journey, but the actual year-over-year improvement is going to depend on total volumes and tariffs. With cruise operations now included in North America, we are continuing to target at least $500 million in year-over-year savings versus in 2025 versus 2024. We anticipate commodities to be relatively flat year-over-year, while rates for steel and aluminum have increased recently, these are somewhat mitigated by our limited exposure to index pricing. For GM International, we expect a tailwind from restructuring the China business and are continuing to target profitable equity income for the full year. GM International outside of China should be similar to what was delivered in 2024. We expect higher profitability in the second half driven by seasonality and some new launches. For GM Financial, we continue to expect EBT adjusted in the $2.5 billion to $3 billion range, and we also continue to expect capital expenditures in the range of $10 billion to $11 billion including battery JV investments. Finally, I'd like to turn allocation. Let me start by reiterating that there is no change to our capital allocation policy. We continue to balance investing in our business, maintaining a strong balance sheet and returning capital to our shareholders. Investing in our business to optimize long term profitable growth remains our top priority. Our balance sheet is strong. On April 1, we paid off $500 million of senior notes, which leaves another $1.25 billion maturing later this year. We will assess refinancing opportunities or debt extinguishment as we progress through the year. We have also entered into an agreement with Ultium Cells to provide a $1.8 billion 5-year term loan that will facilitate a full voluntary prepayment of all remaining amounts under the US Department of Energy's advanced technology vehicles manufacturing loan program. We are grateful for the support of everyone at the local, state, and federal level who helped make these plans possible. Going forward, the JV's simplified capital structure will allow it to grow and evolve with even greater flexibility. Back in February, we announced a $2 billion accelerated share repurchase or ASR, retiring 33 million shares immediately. The total number of shares ultimately repurchased under the ASR program will be determined upon final settlement, which is expected to conclude this quarter. We ended the first quarter with a diluted share count of 983 million shares, down 15% compared to the end of the first quarter last year. GM has $4.3 billion of capacity remaining under share repurchase authorization, but we are temporarily pausing additional repurchases until we have more certainty with respect to our operating environment. In closing, I want to express my sincere gratitude to every member of the GM team for delivering another great quarter. Although the current environment poses challenges, we will navigate this evolving landscape with the same agility and resilience that have defined our successful responses to past industry disruptions. Thank you, and we'll now move to the Q&A portion of the call.
