Thanks, Marc. Good morning, and welcome to MasTec’s 2023 second quarter call. Today, I'll be reviewing our second quarter results, as well as providing my outlook for the markets we serve. First, some second quarter highlights. Revenue for the quarter was $2,874 million, adjusted EBITDA was $255 million, adjusted earnings per share was $0.89 and backlog at quarter end was $13.4 billion. In summary, EBITDA was up $76 million with non-oil and gas EBITDA up 57% year-over-year, EPS was up 42%. And revenue was up 25% year-over-year but about $125 million less than our previous expectations. EBITDA margins improved in every segment in the second quarter, and we expect strong second half performance despite some revenue challenges. I'd like to highlight that our progression -- our margin progression story is greatly intact. And while the lower revenue guidance is having some margin impact on the second half of 2023 margins are generally in line with previous guidance and above 2022 second half performance. I think this is critical as you think about MasTec and our future. I'm highly confident that the goals we set out to show significant margin improvement, specifically in our Clean Energy and Infrastructure segment are proving out. Thus, our challenges in 2023 are predominantly due to revenue misses in some segments, offset by the expected second half revenue increases in our Oil and Gas segment. I'd like to cover our second half of 2023 revenue challenges in more detail. First, let me start with some high level numbers. We still expect 2023 total company revenue growth to exceed 30%. If you exclude IEA from this calculation, so think of it as MasTec mastic pre IEA, we're expected to grow 18% organically, there is about a 5% to 6% bump from the MVP pipeline in that number. So even excluding MVP, we expect double digit organic full year total company revenue growth, albeit slightly lower than our previous expectations. Let me cover some segment revenue expectations in detail. In our Communication segment, we now expect 5% year-over-year with second half revenues flat to last year. The softness is predominantly in the wireless area, where our customers are moderating their 2023 spend plans. We still expect wireline activity to increase about 20% over last year and see further opportunity in 2024 as large off balance sheet deployment projects begin to generate revenues. We believe the communications market continues to be strong, with some short term impact as our customers adjust to the economic and interest rate environment. Our Power delivery revenue expectations are generally in line with previous expectation with slightly lower predicted strong revenue, which could quickly change. Our Oil and Gas revenue is expected to be about $2 billion or roughly a $500 million increase from previous expectations due to the restart of the MVP project. Finally, I'd like to cover our Clean Energy and Infrastructure where we are having the most significant revenue challenges. Again, let me start with some high level numbers. We currently expect full year 2023 segment revenues of about $4.5 with MasTec’s legacy renewable and infrastructure business contributing approximately $.5 billion This compares to $2 billion last year for our legacy business or about 25% organic growth. IEA is now expected to generate approximately $2 billion of revenues in 2023, versus our original estimate of $2.5 billion, and the $2.4 billion they generated for the full year of 2022. Thus, IEA has a negative organic growth of approximately 16% in 2023, or a $500 million decline versus our original expectation. So I'd like to cover IEA and our clean energy segment in some detail. Again, 2022, revenue for IEA was roughly $2.4 billion, and our expectation for 2023 was for mid-single digit revenue growth, knowing that the wind market would be softer offset by a growing solar market. The 2023 plan, which we've added after acquisition was detailed by projects and customers. First, and second quarter revenues tracked generally in line. But as the second quarter develop, many of the projects that were supposed to start in the latter part of the second quarter, and even into the third quarter began getting pushed into later in 2023, or into 2024. As the year has played out, there has been a big difference in customers’ ability to execute on their project pipeline. We knew that the project analysis would be very important in 2023. As evidenced by our legacy businesses expected 25% organic growth this year, we think we did a really good job of understanding that in our legacy business. While we're excited about the relationships IEA has and the demand they are seeing, we collectively misjudge IEA second half year project pipeline risks and potential. It's also important to note that these aren't canceled projects, rather deferred into future periods. While we're obviously very disappointed with this adjustment to guidance, we do still expect significant second half of the year revenue growth, both at IEA and for a clean energy and infrastructure segment. Segment revenue is expected to grow 48% in the second half versus the first half albeit below our expectations. As we finish out 2023 and prepare for 2024., we believe we are bringing the right scrutiny to the IEA projects as we fill our 2024 pipeline, and believe we will be much more consistent in our revenue predictability. Again, it's taken us time to both get to know the IEA customer base, and the company’s thought process around revenue expectations. While we believe 2023 represented a unique set of challenges. MasTec’s detailed review and risk assessment process will add a lot of value to IEA and its ability to properly forecast revenue. We also believe that the industry is better prepared to deal with supply chain, interconnect and permitting issues going into 2024. Demand for our renewable services for 2024 is unprecedented. At the start of 2023, we strongly believe that one of our main goals and objectives of the year to drive shareholder value had to be our ability to show significant margin improvement in our clean energy and infrastructure segment. I want to emphasize again, that while we're disappointed with our revenue miss, we believe our margin goals in the second half of 2023 are unchanged. We expect to achieve these goals without the cost absorption afforded by our previous revenue guidance. Thus, as our revenue increases in the 2024, and we benefit from this operating leverage, we believe our ability to expand margins further actually improves. Moving to our Oil and Gas segment, we started re-mobilizing onto the Mountain Valley Pipeline. While we had some starts and stops in the last month, we now expect to reach full capacity by the end of September. Since MVP wasn't originally contemplated in our year, we juggled lots of projects with customers, and will ultimately have just under 4,000 people and over 1,100 pieces of equipment deployed on the project. In our guidance, we've assumed completion in 2024. We expect full year oil and gas revenues to approximately $2 billion or up about $500 million from previous guidance. And we now expect 2024 to approximate similar revenue levels. In our Communication segment, we continue to see strong wireline demand with some softness in short term wireless spends, with continued federal dollars available for fiber and broadband expansion and funds beginning to be distributed through the state level. We continue to be very bullish about those long-term opportunities. Finally, our Power Delivery segment is performing as expected. While we see some utilities managing capital budgets a little tighter, we continue to see strong demand. With the expected significant acceleration of renewable projects, we're seeing utilities and developers increased the demand for both new grid construction and upgrades. To recap, we're pleased with our margin performance to date, and expect continued progress through year end. While we expect strong organic revenue growth for both full year and second half of 2023, we're disappointed we didn't manage our renewable revenue expectations better. We believe we've implemented the right process to ensure much better revenue predictability in the future. And we continue to be very excited about our future growth opportunities for 2024 and beyond. I'd like to take this opportunity to thank the men and women of MasTec. I'm honored and privileged to lead such a great group. The men and women of MasTec are committed to the values of safety, environmental stewardship, integrity, honesty, and in providing our customers a great quality project at the best value. These traits have been recognized by our customers. And it's because of our people's great work that we've been able to position ourselves for continued growth and success. I will now turn the call over to Paul for our financial review. Paul?
