Please turn to slide 10. As I said in my opening remarks we are very pleased with the first quarter. Our operations continued to perform well in Q1 and I continue to commend the team for their performance. Every quarter in the recent past the company is pushing more volume through our three plants that we've ever seen before. Organic volume growth was up 23.5% and on a two year stack, it was up 44.8%. We've made great strides at increasing our production capacity to allow for this growth. Total headcount was up 27.3% from a year ago, and up 10.4% from the end of 2022. We continue to do a great job at onboarding new employees. More importantly, we're efficiently integrating them into our operations so as not to disrupt productivity and profitability. We're also investing in new equipment. Sheet metal production is running at high utilization rates. We are investing in new [indiscernible] machines both to replace old machines that will enable us to increase productivity, as well as to add incremental sheet metal production. Supply chain issues continue to be a challenge. They seem to be slowly improving, but they still very much exist. This continues to weigh on productivity and output. Without them volumes most likely would be stronger and productivity certainly would be better. That said our productivity associated with dealing with these issues continues to improve. Lastly, volume growth was also a reflection of our premier sales channel and the backlog our rep partners have been able to generate for us. AAON has never been more aligned with its sales channel partners and has never supported them as much as we are now. Last month we had the grand opening of our exploration center, located at our headquarters in Tulsa. This is the latest example of how we are supporting our partners. This is the first of its kind in the industry. The building is a 27,000 square foot showroom that showcases our equipment side by side other market alternatives. Nowhere to this scale can customers go to see and compare AAON product next to market alternatives. Sales reps will use this to help customers better understand the value proposition that AAON equipment provides. Our sales channels has never been as strong as it is right now and we're giving them more tools to help them to be even more successful. Now please turn to slide 11. I want to discuss our gross margin performance and outlook. The 29% we posted in the quarter was in line with our internal expectations. As we stated on our fourth quarter call, and as Rebecca stated today, there were some onetime expenses that weighed on the margin. We anticipated the first quarter to be a low watermark, and continue to expect improvement throughout the year. In addition to certain expenses in the first quarter, not recurring, we have more price coming. Meanwhile, input cost inflation is moderating. Productivity is also expected to improve throughout the year. Most headcount additions will occur in the first half of the year. As that new headcount is integrated, trained and fully up to speed, we expect productivity will improve, which we expect will occur in the second half of the year. All in all, we maintain the view that 2023 gross margin will be better than the fourth quarter of 2022. Now moving to slide 12. Overall demand remains very strong. Bookings in the first quarter were the strongest of any quarter since the first quarter of last year. And if not for a large price increase we had on March 30 of last year, which resulted in a big pull forward of orders, this past quarter would have likely been a company record. Despite the robust growth in volumes and significant increase in production capacity, bookings continued to outpace sales. Total backlog was up 30% from a year ago, and up 9.5% from the end of the fourth quarter. Many factors are contributing to the robust demand, including favorable lead times, a narrowing price premium between our equipment market alternatives, the attractive value proposition that AAON equipment has to offer, the strengthening of our sales channel, robust growth at basics and favorable secular market trends related to decarbonisation, electrification, energy efficiency, and new governmental regulations. Please turn to slide 13. Our lead times have continued to extend. We still maintain industry best lead times, but the gap has begun to narrow. We're doing our best at reversing this with the investments we're making and production capacity. CapEx is expected to be up 150% this year, of which a vast majority is related to increasing production, and we're increasing headcount. Considering that I'm optimistic that lead times have peaked. Please turn to slide 14. Demand continues to be fairly broad based as far as in markets. Data centers and semiconductor markets are very strong. Basics had a very good quarter as far as bookings. The K-12 Education vertical is solid. Healthcare and manufacturing are also still very good. We continue to see robust demand in the grow facility market and while new construction warehouse is slowing, the end market remains good for us due to retrofit work. Overall demand for us is solid across most of the board. Sentiment among our channel partners remains positive. Compared to a year ago, it may not be quite as strong, but overall sentiment is still very positive. Macro data is also still solid. Construction spending is now well beyond pre-pandemic levels, and construction starts at the strongest levels in years. The ABI and the Dodge momentum index, which tracks the pipeline of non-residential projects early in the planning stages have recently peaked, but they still imply the pipeline is still at historically high levels. Please move to slide 15. Part sales grew 38.5% in the quarter, and on a two year stack they were up 88.6%. The business declined to 5.3% of total sales, but that was due to the robust growth of equipment sales. We remain optimistic through the rest of the year. Despite the positive outlook, parts continue to feel effects from the supply chain issues. As those issues dissipate, we expect part sales accelerate. Long term we continue to anticipate this business will become a larger part of the company, both on a sales and profitability basis. Now please turn to slide 16. Before finishing up and handing off the call for Q&A, I want to provide some information on our outlook for the rest of the year. Based on the size and improving margin profile of the backlog, increasing production capacity and productivity and strong order trends we anticipate sales and earnings will improve sequentially through at least Q3. We continue to anticipate pricing will be low double digit contributor to sales growth for the year. For gross profit margin, we anticipate gross margin will improve throughout the year. For SG&A we're making several investments that will help position the company better for long term growth. This will limit the operating leverage you usually tend to see with SG&A. We continued to think SG&A as a percent of sales will be slightly higher than what we realized in 2022. Finally, CapEx will be approximately 135 million. In closing, I want to finish by thanking all of our employees, our sales channel partners and our customers. I also want to remind everyone we will be hosting an investor Day on May 17 and 18th at our headquarters in Tulsa. You can find more details on this event in the investor relations section of our website. We will also be attending Wells Fargo's industrials conference on June 13. I hope to see some of you at these events. Thank you and I will now open up the call for question and answers.
