Thank you, Pat and good morning everyone. I'm pleased to report Oshkosh Corporation's strong results for the first quarter of 2023 with revenues of $2.3 billion and adjusted earnings per share of $1.59, both representing meaningful improvement over the prior year quarter. We continued the positive momentum that began in the second half of 2022 and our teams remain focused on solid execution for our customers. As a result of our strong Q1 performance, robust demand, and progress on our key operational initiatives, I'm pleased to announce that we are raising our full year adjusted earnings per share expectations to be in the range of $6 compared to our previous estimate of $5.50. Mike will provide more details in his section. Our Access segment led the significant year-over-year improvement by delivering operating margin of 11.3% in the quarter. Order flow across the board was robust during the quarter at just over $3 billion, driving another consolidated record backlog approaching $15 billion. we remain confident in both near-term and longer-term growth. We view construction markets as strong, particularly with the large number of mega projects around the country. In fact metrics for the vast majority of construction categories point to continued growth for the foreseeable future. The access equipment fleet age remains elevated and new use cases continue to grow beyond construction. Our view on our end markets was bolstered by recent discussions with customers at the ConExpo Show in March. We also see healthy demand across the fire truck, RCV, and delivery markets as well, bolstered by solid market dynamics and long-term growth driven by our new electric vehicle offerings. We are investing in capacity, as well as exciting new products that support our plans for growth to drive long-term shareholder value. Notably, we're investing in capacity for our USPS next-generation delivery vehicles, our vocational segment for both e-RCVs and pierce fire trucks, as well as our Access segment, where we are transitioning 500,000 square feet to telehandler manufacturing in Jefferson City Tennessee. We also took a number of important steps in the quarter to continue to expand our portfolio with next generation of innovative products. We completed the acquisition of Hinowa in our access segment and look forward to attractive growth opportunities with this well-run Italian manufacturer of Compact Crawler Booms and tracked equipment. In February, we announced the launch of the first fully integrated purpose-built all-electric refuse collection vehicle in our new vocational segment. I'll talk more about this revolutionary new product in a few minutes. Additionally, we're pleased with the integration progress for the vocational segment, which we view as an outstanding growth platform for Oshkosh. Last quarter, we announced plans to combine our fire & emergency and commercial segments to drive enhanced efficiencies, while better leveraging our scale and technology development at an accelerated pace. We also completed the divestiture of our rear discharge concrete mixer business in the quarter to further focus on our core growth areas. And finally, we're honored to have been selected with the world's most ethical designation for the eighth consecutive year. Please turn to slide four and we'll get started on our segment updates with Access. The team at Access built on their strong finish to 2022 with an excellent first quarter in 2023. We benefited from better-than-expected shipments due to modestly improved supply chain conditions. While supply chain challenges remain, we are seeing progress with supplier on-time delivery metrics, as well as the many actions we have taken to improve throughput. Demand remains very strong for JLG aerial work platforms and telehandlers, as fleet ages remain elevated. In fact, fleet ages have not improved since we reported average fleet ages in North America of over 60 months during our Investor Day in May of 2022. New use cases, as well as technology innovations continue to improve demand for our products. In addition to fleet ages, we believe high equipment utilization rates and the impact of mega projects and other construction verticals, continue to point to strong demand for our market-leading JLG products for the foreseeable future. Orders remained healthy at $1.2 billion in the quarter leading to another record backlog of $4.4 billion. We believe that 2023 will be a strong year, with revenues limited by supply chain conditions. While we do not expect significant supply chain improvement in 2023, we are well positioned to deliver stronger results in the event supply chain improves faster than current expectations. Please turn to slide five and I'll review our Defense segment. As expected, Defense segment revenues were down year-over-year in the quarter in line with customer requirements, continued inflation including higher-than-expected steel cost forecast contributed to the low operating margin in the quarter. As discussed last quarter, we believe that Q1 will be Defense's lowest quarter of the year for operating income. In February, we were disappointed to learn that we did not win the JLTV follow-on contract. The contract was won at a pricing level that would be unacceptable to Oshkosh. Of course, we are protesting the award based on the evaluation of financial, operational and technical capabilities. In short, we believe the US Army is assuming significant risk based on their decision and we expect the Government Accountability Office to issue a judgment in mid-June. As a reminder, we expect to deliver JLTVs through the end of 2024 under the current contract. With the tactical wheeled vehicle market under pressure, we continue to focus our efforts on more fruitful product categories such as combat and delivery. We have won some outstanding contracts and are vying for others. The DoD's down-select decision for the next phases of the Optionally Manned Fighting Vehicle or OMFV program is expected this summer. We are confident that our proposed solution delivers a high level of innovation and technical capability, which we believe places us in a strong competitive position for the program. Awards are expected to be announced for three competitors with a value for each bidder expected to be $886 million over a 54-month period. We are also competing for other attractive programs such as the Robotic Combat Vehicle or RCV. We continue to execute on our NGDV program for the United States Postal Service with plans to ramp up production in 2024. Several months ago the USPS expressed their intention to significantly increase the percentage of battery electric or BEV NGDV units in their initial delivery order. During the quarter, we received a delivery order modification that reflects the richer mix of BEV units. This is good news for the USPS, good for communities across the country, and good for our product mix. We are excited about the growth of this business as we head towards launch. Let's turn to slide 6 for a discussion of the vocational segment. During our last earnings call we announced the decision to combine our Commercial and Fire & Emergency segments to form a new segment we call our vocational segment. We believe that the new segment provides opportunities to drive enhanced efficiencies and better leverage scale and technology development at an accelerated pace. The vocational segment also serves as a platform for both organic and inorganic growth opportunities in several important end markets. We are in the process of integrating the businesses, which will continue throughout 2023. Since our announcement three months ago Jim Johnson and his team have evaluated opportunities and implemented numerous changes to our structure that are expected to generate $15 million in annualized cost synergy benefits. The savings are a result of both back office optimization, as well as leveraging shared manufacturing in our new factory in Murphysboro, Tennessee. We expect a modest impact in the second half of 2023 and the full $15 million run rate in 2024 as we ramp -- wrap up transition services related to the divestiture of the rear discharge concrete mixer business. Cost synergies are only a part of the story as we also expect to benefit from joint development for advanced technologies, particularly with electrification and autonomy. Additionally, we expect to benefit from channel synergies. We will continue to provide updates on our integration work and synergy opportunities in coming quarters. Demand for fire trucks remains very high, driven by aging fleets and solid municipal budgets. We are continuing to invest in automation and capacity enhancements, at our fire truck facilities in Wisconsin. We believe this improved capacity will help us reduce lead times that have led to a very large backlog for custom fire trucks. We believe the actions we are taking to improve parts supply, as well as our capacity expansions, including Robotic painting in Appleton, will help us increase output in late 2023 and into 2024. Of course, the biggest news for the segment came in February when we debuted, our brand-new state-of-the-art, fully integrated electric refuse and recycling collection vehicle. Customer reaction has been outstanding for this revolutionary, zero emission vehicle. This is the first ever fully integrated vocational vehicle, built for the RCV market and its zero emission fully electric. The e-RCV with unmatched ergonomics, supports a wide range of driver body types, drive strong productivity gains and supports lower total cost of ownership, for our customers. So you can understand, why the reception has been so strong. We will be showing the unit at Waste Expo next week, and displaying the cab for demonstration using VR technology at the Advanced Clean Transportation Expo, also next week. Initial vehicle deliveries will start in 2024, and we will be ramping up from there over the next several years. With that, I'm going to turn it over to Mike, to discuss our results in more detail and our expectations for 2023.
