Thanks, John. I'll start on slide five with a summary of our second quarter results compared to the prior year. As John mentioned, the company delivered record second quarter sales. Year-over-year increases in our CSS and UBS businesses were partially offset by a decline in sales in certain EES markets. On an organic basis, sales were up 3% over the prior year, driven mostly by a low single-digit contribution from price as volume was flat. The flat volumes in the quarter represent a modest year-over-year decline in market volume that was fully offset by our strong cross-sell results. During the quarter, we experienced some negative impacts from supply chain rebalancing and the normalization of product lead times. As lead times extended at the start of the pandemic, customers increased purchases to offset the impact. As the supply chain heals, we are now seeing a rapid reversal of those behaviors, which has led to destocking and a temporary decline in our stock and flow activity levels in certain customer verticals, while underlying end market growth remain stable. Project backlog continues to be at historically high levels, supporting our outlook in the second half of 2023 into 2024 and beyond. In total, backlog was up 6% year-over-year and down approximately 2% sequentially from the end of March. Gross margin of 21.6% was stable year-over-year after adjusting for the impact of business unit mix during the quarter. We continue to prioritize profitable top line growth. And, as the industry leader, we intend to protect the progress we've made on gross margin with continued execution of our enterprise-wide margin improvement program. Adjusted EBITDA was flat with the prior year. Higher SG&A costs, which have been addressed through our cost-reduction actions was the primary driver of the reduction in EBITDA margins year-over-year. Adjusted diluted EPS for the quarter was $3.71, 11% below the prior year as the contribution from Rahi was offset by foreign exchange rates, higher interest expense, a higher effective tax rate and higher share count. As we start the third quarter, end market demand trends are sequentially in line with the seasonality of the past two years. July preliminary sales were up 3% with growth in CSS and UBS, partially offset by a decline in EES, driven by construction and OEM, consistent with what we experienced in the second quarter. Turning to page six. This slide bridges the year-over-year changes in sales and adjusted EBITDA. As I mentioned a moment ago, organic sales increased 3% versus the prior year, including a 3% benefit from price, while volumes were roughly flat. Market volumes declined and were offset by higher incremental cross-sell gains. As expected, the contribution from price moderated again in the quarter relative to 2022 as there have been fewer supplier price increases and the magnitude of these increases has been smaller. Additionally, decreases on pure commodity products was a headwind to pricing in the quarter. Adjusted EBITDA was flat versus the prior year as the benefit of higher sales was offset by higher compensation and volume-related costs and higher costs associated with our digital and IT transformation. We have already taken steps to address the higher costs through a series of actions taken in June that will benefit the second half of the year. These actions will generate $25 million of annualized cost savings. Turning to slide seven. Organic sales in our EES business were down 5% year-over-year or down 3% excluding the impact of the intersegment business transfers that we initiated in the first quarter. The 3% like-for-like reduction in sales versus the prior year was primarily driven by the combination of two factors. First, construction was down mid-single digits due to supply chain rebalancing, leading to lower stock and flow sales with contractor customers as well as lower wire and cable sales. Second, we experienced continued weakness in manufacturing structures in our OEM operating group. Our industrial sales were up low single-digits driven by continued growth in general industrial, metals and mining and petrochemical markets. Backlog was up 9% over prior year, up 3% sequentially, driven by strong bookings for large projects. More than a third of the backlog supports top line growth in 2024 and beyond as we are now beginning to win larger mega projects associated with the unprecedented levels of infrastructure investments in North America. In the second quarter, adjusted EBITDA was down approximately 20% from the prior year. Adjusted EBITDA margin was 8.6%, 150 basis points lower year-over-year. The reduced profitability in EES was driven by the lower sales level and higher SG&A. We expect EES adjusted EBITDA margins to improve modestly in the second half of the year, driven by operating leverage on seasonally higher sales, along with the SG&A reductions initiated in the second quarter. Turning to slide eight. I mentioned that EES backlog was up in the quarter driven by larger project wins. This page provides an example of the scale, scope and power of one of those mega project wins. We were awarded a $120 million multiyear contract to support the construction of a new electric vehicle manufacturing facility. The initial award was specifically focused on switchgear. However, due to our total solutions offering and cross-sell initiatives, we were able to substantially increase the scope of products and solutions that we are supplying. This project win is an excellent example of the success of both our cross-sell program and the secular trends of electrification and reshoring. Shipments are scheduled to begin in the second half of this year. Turning to slide nine. Sales in our CSS business were a quarterly record and up 16% versus the prior year on a reported basis. Organic sales were up 7%. We saw good growth in network infrastructure, up low double-digits, driven by data center and cloud applications. We saw substantial growth to hyperscale data center customers, driven by both Rahi and growth in our legacy data center business. Sales to Internet service providers who supply 5G, fiber and satellite connectivity were down mid-single digits. Security sales were up high single-digits and professional audio visual installations were also up double-digits, driven by strong international sales. Profitability was also strong with record Q2 adjusted EBITDA and adjusted EBITDA margin of 9.7%, 30 basis higher than the prior year, driven by operating leverage, integration cost synergies and the continued successful execution of our margin improvement initiatives. Turning to page 10. We noted the strong growth in data center demand for CSS in the quarter. The long-term trends remain healthy as global data center customers provide dynamic and exciting business opportunities due to accelerating data consumption, increased adoption of the cloud and ongoing demand for data storage and management. As our data center customers increased their scale, footprint, scope and complexity, our ability to service them as the best tech-enabled supply chain solutions provider is paramount. With our new WESCO data solutions team, inclusive of Rahi, we provide more solutions and focused expertise around the clock and around the world. This business enables us to support all data center environments, including the rapidly expanding AI-driven new build and upgrades by offering complete end-to-end product and service solutions and supporting customers on a global basis. The combined sales of this business represent approximately half of our network infrastructure revenue and is on track to reach approximately $2 billion in sales by the end of the year, with an outlook for strong double-digit growth in 2024 and beyond. Turning to slide 11. Record sales in our UBS business were up 10% versus the prior year on an organic basis in the quarter. We experienced broad-based growth in utility, up low double-digits and integrated supply up mid-teens versus the prior year. Broadband sales were down low double-digits as certain customers continue to work through inventory and delay restocking until government infrastructure funds are allocated. We now expect broadband sales growth to resume in 2024 as customers and the supply chain continue to work through inventory rebalancing and destocking in the second half of this year. Backlog was up 15% over the prior year and down approximately 2% on a sequential basis. Profitability was exceptionally strong with a Q2 record adjusted EBITDA margin of 11.1%, up 20 basis points versus the prior year, driven by operating leverage on higher sales, our margin improvement initiatives and integration synergies. This was the fifth consecutive quarter of adjusted EBITDA margins above 10%. Turning to page 12. As we have said before, the Utility business has some of the strongest secular trends of any of our businesses. Three of the most significant secular trends that are driving growth in our utility business, grid hardening and modernization, investments in renewable power sources and the need for increased grid capacity are a reality today. As we mentioned at our Investor Day last fall, we are seeing the acceleration of grid modernization trends. The US electric grid will require up to $2 trillion of investments over the next 10 years merely to sustain the current level of reliability. That, combined with direct government funding for investments in renewable generation will continue to provide outstanding growth opportunities for our Utility business for many years to come. Collectively, we expect that these trends will double historical utility industry growth rates over the long-term. Now moving to page 13. The size of the cross-sell opportunity continues to exceed our expectations. This quarter, we recognized more than $300 million of cross-sell revenue, the highest in the 12 quarters since acquiring Anixter, and bringing the cumulative total to $1.75 billion since the beginning of the program. Our pipeline of sales opportunities remains healthy and expanded again in the quarter. We are capitalizing on the complementary portfolio of products and services as well as the minimal overlap between legacy WESCO and legacy Anixter customers. As we look at the remaining six months of the program in 2023, we are increasing our expected cumulative total to $2 billion, reflecting the strength of our value proposition against the backdrop of accelerating secular trends. Turning to slide 14. This is a slide that we've shown throughout the integration with the realized cumulative run rate cost synergies of $188 million in 2021 and $270 million in 2022. We remain on track to meet our expected target of $315 million by the end of 2023. Our focus through the balance of the year is on supply chain network optimization and field operations to drive cost synergies. Turning to page 15. Recall that after our cash draw in the first quarter, we said we expected to generate significant free cash flow in the second quarter and be approximately neutral through the first half of the year. We generated $293 million of free cash flow in the second quarter or 141% of adjusted net income and are now positive on a year-to-date basis. The primary driver was working capital management, specifically lower inventory, which represented a source of cash of $150 million. Moving to slide 16. Reducing our leverage has been a top priority since we announced the acquisition of Anixter and we are pleased that leverage is now at its lowest level since closing the transaction in June of 2020. Notable this quarter was that our strong cash flow enabled us to reduce net debt by more than $250 million, which was the primary driver of the lower leverage. We previously indicated our intent to operate with leverage at the midpoint of our targeted range of 2 times to 3.5 times trailing 12-month EBITDA, and we expect to reach the midpoint in the second half of the year. Given that we are close to our target leverage ratio, our capital allocation priorities will be more balanced between share repurchases and debt reduction. Based on the current interest rate and economic environment, we will look to continue paying down debt while opportunistically funding share buybacks in the second half of 2023. Now moving to page 17. This slide shows the uniquely strong position of our company to drive growth and profitability in the years ahead. The end-to-end solutions that we provide to our global customer base are directly aligned with the six secular growth trends shown on the left side of this page. Our participation in these trends, coupled with increasing public sector investments in infrastructure, broadband and partnerships with the private sector, position WESCO exceptionally well. As we outlined at our Investor Day last year, we expect to grow 2% to 4% above the market due to the combined benefit of secular trend growth and increasing share. Moving to page 18. We are updating our 2023 outlook today based on the results of the first half of the year and current market conditions. For the year, we now expect organic sales to be up approximately 4% to 6% versus 5% to 8% previously. The change in our outlook is entirely driven by a down-shift in our expectation for market volume growth. We now expect our market volumes to be relatively flat year-over-year as gains in CSS and UBS are offset by declines in EES, with price driving total market growth of approximately 3% to 4%. Our share gains and cross-sell initiatives remain a powerful driver of our performance and will provide another one to two points of organic growth. After factoring in the additional revenue from Rahi, the impact of one less workday in 2023 and the impact of foreign exchange rate differences, we estimate our reported sales growth will be in the range of 5% to 7%. For our strategic business units, we now expect EES reported sales to be approximately flat year-over-year, versus our prior expectation for mid-single-digit growth. As we noted earlier, we have experienced headwinds in our EES markets that were largely the result of unprecedented supply chain rebalancing that drove customer destocking in the electrical industry, along with select weakness in certain sectors, including the stock and flow portion of commercial construction and manufactured structures. Our outlook for UBS remains unchanged from our prior outlook, with top line expected to be up high single to low double-digits. And lastly, for CSS, we now expect reported sales to be up mid-teens year-over-year versus our prior expectation of high single to low double-digit growth. For adjusted EBITDA margin, our outlook is for a range of 7.8% to 8%, which represents a decline of approximately 30 basis points at the midpoint. This primarily reflects the top line and SG&A margin headwinds experienced within EES. We took actions to address total company costs in June, which will have an annualized benefit of $25 million. Gross margin in the first half of 2023 was stable year-over-year. Sequentially, we expect stable gross margin in the second half of the year as we overcome notable year-over-year headwinds related to supplier volume rebates. Based on current assumptions, supplier volume rebates in the second half will be a headwind of approximately 40 basis points. With the lower EBITDA forecast, we are also reducing our outlook for adjusted earnings per share to $15 to $16 and free cash flow between $500 million and $700 million. Despite the lower expectations for the remainder of the year, this outlook still reflects record adjusted EBITDA, record adjusted diluted EPS and a record free cash flow at the midpoint of their respective ranges. In the appendix of this presentation, we have shown our revised underlying assumptions for certain items on the income statement. We increased the low end of our expectation for interest expense for the year from a range of $350 million to $390 million, to a range of $370 million to $390 million, primarily driven by higher variable rates and the timing of debt paydown in 2023. Additionally, we now expect other expense to be approximately $20 million to $30 million for the full year versus $30 million to $40 million previously. Regarding the quarterly cadence in the back half of the year, we expect Q3 reported revenue to be down low single-digits sequentially. This is in line with the quarterly cadence in 2022 and the trends we experienced in July. In addition, there is one less workday in Q3 versus Q2. Similar to the last two years, we are expecting a low single-digit sequential increase in revenue in the fourth quarter versus the third quarter. Before opening the call for questions, let me provide a brief summary of what we covered this morning. Overall sales were below our expectations in the second quarter. We delivered record sales in both CSS and UBS, which more than offset the impact of supply chain rebalancing and select market weakness within EES. We again took share in most of our operating groups through sales execution in our cross-sell program, and we are again increasing our cross-sell synergies outlook for 2023. Free cash flow was particularly strong in the quarter as we delivered approximately $300 million of cash flow, bringing our year-to-date total to positive. We reduced our leverage this quarter to the lowest level since acquiring Anixter in 2020 and we are approaching the midpoint of our target range. We expect to generate significant cash flow in the second half of the year, enabling continued investment in our strategic objectives and increasing shareholder returns. We continue to expect 2023 will be a transformational year with continued execution of our digital innovatives, strong sales growth and substantial cash generation supporting our value creation initiatives. With that we'll open the call to your questions.
