Thanks Russ. Good morning everyone. Reported revenues for the three months ended December 31, 2023 increased by 3.3% to $1.76 billion, compared to $1.7 billion in the prior year period. Organic growth of 1.5% was driven by strong services revenue, organic growth of 5% partially offset by disciplined customer and project selection, and lower material costs, leading to a 3% organic decline in our projects business versus the prior year. Adjusted gross margin for the three months ended December 31, 2023 grew to 30.1%, representing a 230 basis point increase compared to the prior year period, driven by continuous price increases, outsized growth and higher margin services revenue, as well as the significant margin expansion in our projects business across both segments. Adjusted EBITDA increased by 13% on a fixed currency basis for the three months ended December 31, 2023, with adjusted EBITDA margin coming in at 11.8%, representing a 110 basis point increase compared to the prior year period, primarily due to the factors impacting gross margin partially offset by investments to support revenue growth and the investment in building our global capabilities and infrastructure. I'm pleased to report that adjusted diluted earnings per share for the fourth quarter was $0.44 per share representing an $0.08 or 22% increase compared to the prior year period. The increase was driven primarily by strong margin expansion in both safety and specialty services and decreased interest expense. I will now discuss our results in more detail for safety services. Safety services reported revenues for the three months ended December 31, 2023 increase by 3.1% to $1.24 billion compared to $1.2 billion in the prior year period. Organic growth of 1% comping off an 18% plus growth in Q4 2022 was in line with expectations and was driven by double digit core inspection revenue growth in our U.S. life safety business and 5% organic growth in inspection service and monitoring in U.S. life safety. This was partially offset by flat organic growth in the project business, driven by planned customer attrition in our international business, as well as disciplined customer project selection and lower revenue from declining material cost pass through in our HVAC business. Adjusted gross margin for the three months ended December 31, 2023 was 35.1%, representing a 270 basis point increase compared to the prior year adjusted gross margin, driven by continued price increases, improved business mix of inspection, service and monitoring revenue, as well as a significant margin expansion in our projects business. Adjusted EBITDA increased by 18.8% on a fixed currency basis for the three months ended December 31, 2023 and adjusted EBITDA margin was 15.3%, representing a 210 basis point increase compared to the prior year period, primarily due to the factors impacting adjusted gross margin partially offset by investments made to support revenue growth. I will now discuss our results in more detail for our specialty services segment. Specialty services reported revenues for the three months ended December 31, 2023 increased by 2.9% to $525 million compared to $510 million in the prior year period, driven by a 12% growth in service revenues, partially offset by a 10% decline in projects revenues due to disciplined customer and project selection, and lower revenue from declining material cost pass through. Adjusted gross margin for the three months ended December 31, 2023 was 18.1%, representing a 140 basis point increase compared to the prior year period, driven primarily by disciplined customer and project selection, driving significant margin expansion in our projects business. Adjusted EBITDA increased by 11.3% for the three months ended December 31, 2023 and adjusted EBITDA margin was 11.2%, representing an 80 basis point increase compared to the prior year period, primarily due to the factors impacting adjusted gross margin, primarily offset by timing of year end incentive true ups. Cash flow. As we have highlighted throughout the year, the fourth quarter is our strongest quarter for free cash flow generation and 2023 was no different. For the three months ended December 31, 2023, adjusted free cash flow was $300 million, reflecting an adjusted free cash flow conversion of 144%. For the full year, adjusted free cash flow was $537 million with conversion of 69% representing an improvement of $125 million or approximately 30% when compared to 2022. Adjusted free cash flow generation has been and continues to be a priority across APi and we are pleased that we are able to exceed our adjusted free cash flow conversion target of 65% for 2023. On December 19, we paid down $175 million of our term loan debt, resulting in total repayments in 2023 of $475 million and leaving $330 million outstanding on our term loan due 2026, which leaves our weighted average maturity at approximately five years. At the end of the year, our net leverage ratio was approximately 2.3 times even as we continued margin accretive bolt-on M&A. As we look forward to 2024, we expect to grow our adjusted free cash flow as well as improve our adjusted free cash flow conversion, providing us a significant opportunity for value enhancing capital deployment. As Russ touched on earlier, we have reached an agreement with Blackstone and Viking to retire all the outstanding shares of their Series B Perpetual Convertible Preferred Stock issued at the time of the Chubb transaction. Blackstone and Viking will each exercise their respective right to convert all their Series B preferred stock into common stock, resulting in approximately 32.5 million shares of common stock. Upon conversion, APi will repurchase one half of the converted shares from Blackstone and Viking for an aggregate purchase price of approximately $600 million. The transaction is expected to be financed by an incremental term loan of $300 million plus cash on hand and available credit. As a part of the agreement, Blackstone and Viking intend to effect a coordinated secondary public offering with the goal of selling approximately 8.1 million shares of APi's common stock. Following the sale, it is expected that any remaining common shares owned by Blackstone and Viking would be subject to a 90-day lockup. We are pleased to proactively agree to a holistic approach to retiring our Series B preferred stock with only a modest expected increase in net leverage ratio to approximately 3 times, preserving the strength of our balance sheet. Throughout 2024, we'll continue to focus on generating strong free cash flow, allowing us to accelerate M&A spend versus 2023 while reducing our net leverage towards our long-term target of less than 2.5 times. This transaction collectively is expected to provide some substantial benefits to APi and its common stockholders as it simplifies our capital structure, preserves our strong opportunistic balance sheet, reduces adjusted diluted share count by 16.3 million shares, provides immediate accretion to adjusted earnings per share, eliminates preferred dividend payments of $44 million annually and has no significant impact on our reacceleration of bolt-on M&A. I will now discuss our guidance for Q1 and full year 2024. Based on current exchange rates, we expect full year reported net revenues of $7.05 billion to $7.25 billion, representing mid-single digit organic growth and net revenues driven by expected double digit core inspection organic growth and high single digit service growth mixed with low single digit projects growth as we remain focused on disciplined customer and project selection in our specialty and HVAC businesses, primarily in the first half of 2024. We expect full year adjusted EBITDA of $855 million to $905 million, which represents adjusted EBITDA growth of approximately 9% to 15%. On a fixed currency basis an adjusted EBITDA margin of 12.3% at the midpoint. In 2024, we expect to take another step forward in terms of adjusted free cash flow conversion with a 2024 target of approximately 70% as we move towards our long-term target of 80%. In terms of the first quarter, we expect reported net revenues of $1.56 billion to $1.61 billion. This guidance represents an organic net revenue decline of approximately 4% to 1% as we lap our strong organic growth of 12.1% in Q1 2023 and as we continue to build a smaller, but healthier backlog in our HVAC and specialty services businesses. We also expect to see a continuation of lower material costs resulting in declining price pass through versus the first quarter of 2023, which results in lower reported net revenues. However, those impacts as seen in 2023 will allow us to continue to expand adjusted EBITDA dollars and margin, which is reflected in our first quarter adjusted EBITDA guide of $165 million to $180 million. This represents adjusted EBITDA growth of approximately 9% to 20% on a fixed currency basis and adjusted EBITDA margin expansion of 180 basis points at the midpoint. For 2024, we anticipate interest expense to be approximately $150 million, depreciation to be approximately $80 million, capital expenditures to be approximately $95 million, and our adjusted effective cash tax rate to be approximately 23%. We expect corporate expenses to be approximately $30 million per quarter, with some timing variability throughout the year. We expect our adjusted diluted weighted average share count for the year to be approximately $270 million, taking into account the Series B transaction announced earlier today. Finally, we expect to end 2024 with our net leverage ratio at approximately 2.5 times. I will now turn the call over to Russ.
