chairman and CEO. With me is A.J. Nahmad, President, Paul Johnston, Barry Logan, and Rick Gomez. Before we start, a cautionary statement as always. This conference call is forward-looking statements as defined by SEC laws and regulations that are made pursuant to the safe harbor provisions of these various laws. Ultimate results may differ materially from the forward-looking statements. As we all know, 2025 marked the year of significant regulatory change to next generation equipment containing A2L refrigerants. This transition follows several busy, volatile years beginning after 2019. We navigate navigate it through the COVID supply chain disruptions. Steer an energy rated transitions, refrigerant changes, and now the conversion to new A2L equipment. It has certainly been an adventure, and we look forward to a simpler operating environment this year. Through it all, Watsco, Inc. achieved terrific results, and created immense value for our shareholder. We grew our scale and market share and we adopt added 12 business acquisitions, representing over $1,600,000,000 sales. As announced today, we boosted our annual dividends by 10% to $13.20. This marks Watsco, Inc.'s fifty second consecutive year of paying dividends. And speaks to the confidence we have in our business. We also continue to build and expand our technology platforms. Which provide an immense long term competitive advantages. We believe we operate in a great industry, with strong long term fundamentals and the industry most accomplished leadership team. All with focus on building our long term success. The building on our long term success. Turning to our fourth quarter results. We achieved double digit pricing gains on the new A2L products and raise gross margins by 40 basis points to 27.1%. We have several ongoing initiatives to enhance gross margins with the long term goal of achieving 30%. Unit volumes declined during the quarter, which does not come as a surprise given the strong 20% comparison unit growth rate last year. Let me repeat that. Unit volumes declined during the quarter. Which does not come as a surprise given that last year, unit growth was had a 20% growth rate. Operating efficiency improved as SG&A dropped 2% and this included newly acquired and open look new locations. I expect overall sales performance and operating efficiency to improve now that A2L product transition is largely behind us. We continue to fortify our balance sheet, and we were debt free for the entire entirety of 2025. We also met our $500,000,000 inventory reduction goal established at the end of the second quarter and generated record fourth quarter cash flow of $400,000,000 Looking forward, we are focused on improving inventory turns and generating incremental cash flow. We expect margins to gradually improve as the transition matures, the balance of the SEER. We continue to invest in innovation and technology that separate us from competitors. We have made terrific progress in driving adoption. Ecommerce continues to grow and accounts for 35% of sales. And exceeds 60% in certain US markets. This year, contractors engagement with our mobile app expanded 15% to 73,000 users. The annual run rate of sales through OnCallAir, which is our digital selling platforms used by contractors, saw a 20% increase in gross merchandise value. Of products sold through the platform and reached $1,800,000,000 for the year. We've also made incremental investments to enhance our competing competitive position and add to our long term growth. Yeah. And margin profile. For example, we are developing new technology aimed at capturing more sales to institutional customers. We are accelerating the use of our pricing optimization tools to make the further further progress toward our 30% plus gross margin target. We have launched a new initiative to compete in gross sales in the fragmented nonequipment market. It's parts and supplies we're talking about, which today is roughly only 30% of our sales. And we have begun to harness the power of artificial intelligence, offering potential to further transform our customer experience improve operating efficiency, and create new data driven growth strategies. These investments, along with our scale, entrepreneurial culture, capacity to invest, unmatched in our industry. With that, let's turn to Q and A.
