Thanks, Joe. Welcome, everyone, and thank you for joining us. 2024 is off to a very good start, as shown in the first quarter results. Once again, we exceeded the high end of our financial guidance for revenue and adjusted EBITDA. Our consistently solid performance is the result of being crystal clear on where we are going as a company and then being laser-focused on executing our plans to get there. At Vertex, we have a bold vision to accelerate global commerce. To achieve this, we have built a consistent execution engine that continues to perform quarter after quarter. We deliver end-to-end capabilities for indirect tax to seamlessly connect systems, solutions and data. This unified approach empowers our customers to confidently navigate indirect tax complexities and manage their need for a continuous compliance process. We're able to support our customers throughout their entire digital transformation journey, wherever they run their business, locally, fully in the cloud or somewhere in between. We provide value-added services that help them efficiently integrate their indirect tax into their infrastructure and stay in compliance. And behind the scenes, we have a world-class team dedicated to our customer success at every touch point. This is what enables us to keep delivering differentiated value to our customers with great results for investors. Revenue traction remains strong. Total revenue was up 18.1% in the first quarter and software subscription growth was 18.8%. In addition, cloud revenue growth was 28.3%, which is slightly ahead of our target for the full year. Earnings leverage continues to build as expected. Adjusted EBITDA was $36.5 million or 23.3% of revenue. This is up 80% from last year's first quarter. I'll also note that we delivered positive free cash flow in the first quarter, which is typically our lowest quarter of the year from a cash flow standpoint. This bodes well for cash production for the rest of the year. In addition, this quarter, ARR was $525 million, up 17.5% year-over-year. NRR was 112%, up 2 full percentage points compared to last year's first quarter. Average annual revenue per customer increased 17% year-over-year to $121,720. Scaled customer count, which represents customers delivering annual revenue of over $100,000 grew 13% year-over-year and GRR was 95% in the first quarter, which falls within our targeted best-in-class range of 94% to 96%. I'm incredibly proud that Vertex's leadership in the indirect tax technology space was recognized by the financial markets last month when we raised $345 million of convertible debt that we can invest in our business. Convertible debt investors were extremely enthusiastic about Vertex, our business strategy and our growth prospects. They appreciate our consistent high-teens revenue growth as well as our ability to operate profitably and deliver positive adjusted EBITDA and free cash flow. This capital will enable us to be agile, proactive and decisive in seizing growth opportunities, whether through organic investments or acquisitions. Our financial flexibility and our balance sheet has never been stronger. Now turning to notable wins in the quarter. Our results confirm that the market for indirect tax software is underpenetrated and many companies are still handling their indirect tax needs with homegrown solutions. As the persistent tailwinds of business expansion, regulatory pressures and digital transformations continue to pressure tax departments, we believe that the opportunity to deliver our tax solutions to the market will grow. I will highlight some key new logo wins which pays this off. In the first quarter, we won a mid-6-figure deal with a global provider of power management solutions. This particular deal highlights 2 growth pillars for Vertex: the anticipated wave of ERP conversions that will happen as a result of SAP's decision to end mainstream support for ECC in 2027; as well as the sales partnership we have built with the SAP direct sales force. In this case, the customer was migrating to S/4HANA as part of their digital transformation project. This was a catalyst for them to evaluate indirect tax and determine it was time to replace their homegrown solution as they were previously manually updating rules and regulations in their purchasing system. As we have discussed, one of our growth investments was building a more tightly aligned partnership with SAP on the go-to-market front, and we are seeing ongoing traction from this investment. This deal is an example of how that partnership is bringing new customers to Vertex as we were referred in by the SAP sales team. In addition to the credibility boost that we enjoy in this case, the SAP referral enabled us to get an early look at the customers' infrastructure and tailor our solution accordingly. Another new logo we won in the first quarter was a global risk management consulting firm that had grown through hundreds of acquisitions over the past several decades. They were using a homegrown indirect tax calculation and compliance system, but recent audit pressure had made it clear that the company outgrew its old ways of doing things and needed a more sophisticated solution. Due to the acquisitions, the customer systems environment was extremely complex, which competitively gave us an advantage due to our experience connecting multiple platforms to a single tax solution. In this case, we integrated with multiple systems, including Oracle, Workday, Salesforce and JD Edwards as well as the customer's homegrown billing systems. We had a great win in the quarter with a cloud-native cybersecurity company. After being acquired, our customer underwent a transformation initiative to move their tax solution to the cloud. Even though the new parent currently uses one of our competitors, our cloud solution was chosen because the team was familiar with our proven track record and we were able to meet their accelerated time line. We also won a mid-6-figure deal with a new customer as a manufacturer of industrial machinery. It's another case where an S/4HANA transformation led the company to reevaluate how it's handling indirect tax. The company selected Vertex solutions for tax calculation as well as compliance and reporting solutions for both North America and Europe. They also licensed Vertex PLUS tools for SAP and our certificate center. One of the biggest sources of new revenue for Vertex and a sustainable driver of NRR growth is increased business with our existing customers, the expand part of land and expand equation. A customer in the consumer products space fueled our Q1 growth with a mid-6-figure revenue addition. Their SAP infrastructure upgrade presented an ideal opportunity to move their Vertex solution to the cloud and expand entitlements by $15 billion. They also saw the value of our tax accelerator and Vertex PLUS tools for SAP. While they evaluated competitive options as part of their process, our unmatched SAP expertise and solutions, that ultimately differentiated Vertex. Our unique capabilities delivered a lower total cost of implementation and ownership while minimizing risk. To further optimize their tax processes, our consulting team is collaborating with them to streamline current indirect tax calculations and compliance. Also in the first quarter, we expanded our relationship with a long-time customer in [ the ] medical diagnostics industry. They advanced their corporate cloud strategy by migrating 2 of our legacy solutions to our modern cloud offering. This, in turn, consolidated their tax operations onto a single platform, seamlessly integrating with Salesforce Commerce Cloud, PeopleSoft and their internal billing systems. Other fundamental business changes such as M&A, divestitures and adoption of new modes of commerce can also drive new business for Vertex. In the first quarter, we landed a new customer in the contract research industry that was being spun out by its parent. In this case, the company needed an indirect tax solution to pair with its implementation of Workday financials. Their Big 4 accounting firm conducted an RFP and Vertex prevailed. Similarly, in the security industry, we want to deal with a company that was being sold to a private equity firm. The customer selected Vertex for indirect tax to integrate Microsoft D365. Finally, on the international front, we had a nice win with a growing marketplace provider. When the customer first looked for an indirect tax solution, they went with a competitor. But over the course of their journey, things didn't go well. They didn't get the support they needed. Our competitors' transaction-based pricing model led to massive cost overruns. Ultimately, after 18 months of frustration, the customer changed direction and came back to Vertex. A quick word on how we are addressing e-invoicing. We remain committed to our strategy of delivering a continuous compliance solution, which provides for a single cloud portal to address the e-invoicing through to compliance process, of which e-invoicing is just one piece. As we noted last quarter, after we opted out of the bidding war, in the near term, we continue to utilize Pagero as a partner in alignment with our commercial agreement. However, we are also evaluating our options and developing partnerships with additional players in this space. We will have more to share on this in the coming quarters. As I look back on the strategic growth investments we made from 2020 through 2023 and how they are helping us better serve our customers, I am thrilled with our position in the market and the opportunity in front of us. Our product portfolio, tax content database, go-to-market expertise and scalable infrastructure has us well positioned for a nice run of revenue growth, increasing profitability and solid cash flow to reward our investors. John will now take you through the financials. John?
