Welcome, everyone, and thank you for joining us. In the second quarter, we delivered results that were in line with our guidance and investor expectations. However, as the quarter progressed for the first time, we saw macroeconomic factors that have been noted in the software industry in 2025 and impact our customers and begin to affect their activity with us. We took action to mitigate this, but it necessitated a reduction in our full year guidance. We will discuss all of this in today's call. For the second quarter, revenue was $184.6 million, up 14.6% year-over-year. Subscription revenue grew 15.7% and cloud revenue growth increased to 29.9%. Adjusted EBITDA rose to $38.4 million, representing an EBITDA margin of 20.8%. In addition, annual recurring revenue, or ARR, grew 16.1% to $636.6 million. Average annual revenue per customer for Vertex stand-alone increased 12.7% year-over-year to $142,600. Growth in scaled customer count was 16%. As a reminder, this number represents our customers with annual revenues greater than $100,000 and demonstrates our ongoing success in the underpenetrated enterprise market. Gross revenue retention or GRR, remained at 95% in the second quarter within our targeted best-in-class range of 94% to 96%. Finally, net revenue retention, or NRR, decreased to 108%, down 1 point from the first quarter. We attribute the decrease to 2 main factors: lower growth of additional entitlements as our customers' annual growth has slowed, keeping them within current bands of usage and recent regulatory changes in Brazil created a compliance confusion for customers, which resulted in delayed deal activity for some of our large multinational customers. More broadly, in addition to the macro impacting our customers' growth rate, we have seen a slowdown in ERP migrations, thus elongating our deal cycles. This is consistent with what publicly traded ERP providers noted in their quarterly earnings reports. This has the downstream impact of also pushing out pipeline build. We attribute this to the overall macro environment as our enterprise customers are being more cautious about software spend. As a result of this, we recognize the need to take immediate actions to control expenses and deliver on adjusted EBITDA margins. These included leveraging efficiency from internal technology investments and reducing planned head count growth, which will give us better expense trajectory as we look into 2026 and beyond. John will discuss how all of this impacts our guidance in his remarks. The short-term environment does not impact our confidence in the long-term growth expectations we shared at Investor Day earlier this year. This is because our business has multiple significant tailwinds, many of which are still ahead of us. First, the ongoing cloud ERP upgrade cycle. This has been stubbornly slow in 2025, as I mentioned earlier. However, deadlines for conversion are looming over the next 2.5 years, and we fully expect this motion to accelerate over this time frame. Second, governments all over the world are looking for new ways to generate revenue to meet their obligations and reduced federal funding in the recently passed U.S. tax bill will further pressure state and local budgets. In our 2025 midyear U.S. rates and rules report, we noted that the U.S. saw a 24% increase in sales tax rate changes and new rates compared to the same period last year. This, in turn, creates complexity and increases demand for our solutions. In Europe, the regulatory mandates for VAT and e-invoicing are accelerating, and this is expanding now to parts of Asia Pacific and Latin America. In Brazil, tax reforms underway are making companies completely revisit their existing compliance and technology road maps. We believe even more changes are likely as inflation, global trade disruptions and federal tax policy around tariffs compound to create both opportunity and uncertainty. This is the hallmark of what we do best, make sense of that complexity for global companies at scale. Additionally, our win rates in the enterprise market remained consistently strong, and several of these delayed deals have now already closed in the third quarter. This confirms our experience that the strong underlying demand and customer commitment that we've worked hard to earn remains solidly in place despite deal timing being impacted by larger forces. The durability of our customer base remains outstanding. Churn was lower on a dollar basis in the second quarter compared to both the first quarter and the same period last year. This demonstrates strong product stickiness and high customer satisfaction, providing a robust foundation for future growth. In addition, our team secured some key new logo wins in the Oracle and SAP ecosystems as well as several e-invoicing successes that mitigated some of the second quarter headwinds. In context with these long-term growth drivers, let me share some highlights from the second quarter, particularly around Europe, e-invoicing and the investments we've made in our global platform. We had good momentum in Europe, which was in part driven by accelerating growth at Ecosio, where annual recurring revenue reached $10.8 million, a 33% increase from the prior quarter. We are seeing strong deal flow driven by the upcoming launch of e-invoicing in Belgium, which is mandating the use of e-invoicing beginning on January 1, 2026. The acceleration in demand due to the Belgian e-invoicing launch bodes well as the 2 largest economies in the EU are still on the horizon, with brands set to begin mandating e-invoicing beginning in September 2026, in Germany beginning January 1, 2027. Our growth thesis in e-invoicing is unfolding as anticipated. Customers who adopted our solution earlier this year are already returning to license additional country coverage. Early indications suggest that e-invoicing is shaping up to be a classic land and expand motion, mirroring the trajectory of our core indirect tax business and supporting sustained NRR growth. Our e-invoicing solution has also been recognized by industry experts. In July, Gartner included Vertex in its research study, developed a global invoice and compliance strategy supporting global e-invoice and compliance efforts. From a product standpoint, we continue to build the global compliance platform of the future, combining thoughtful AI and automated workflows, tightly embedded in our ecosystems and powered by our content and data. It's a strategy that's resonating with our customers and partners around the world. Our Kintsugi investment is accelerating our second half AI road map supporting new product functionality, increased efficiency and a greater customer experience. This relationship has also generated opportunities to support their focus on the good enough requirements of the SMB market. Also on the AI front, we are working with several AI and cloud hyperscaler providers and ecosystem partners on using Vertex's agentic AI agents natively within their application workflows. These agents work within the ecosystem and leverage the services of our Vertex Cloud platform to orchestrate more advanced capabilities. These Vertex value- added AI agents can be seamlessly enabled within the marketplaces of the enterprise application providers and embed it within the financial and compliance workflows, enabling a new level of customer value and stickiness. As an example, in the Microsoft Azure ecosystem, we built strong relationships at the executive, technical and go-to-market levels, coupled with new AI innovations, this will continue to enable us to expand our mid-market opportunity even further. In addition, we launched CoPilot within our platform, giving customers in platform knowledge and product documentation with a single click. Feedback has been great and adoption continues to grow. I'll now highlight a few new business wins. Among our installed base customers, we are seeing a growing trend towards globalizing their tax operations, driving both more usage of our solutions and expanding our footprint. Example, in the second quarter, a leading European truck manufacturer, which has been a Vertex customer since 2009, expanded its relationship with Vertex during an SAP ECC to S/4 migration. The customer, which had previously licensed Vertex only for its U.S. operations, expanded its entitlement and license additional Vertex tools. This led to mid-6 figures of additional annual revenue and nearly doubled our annual volume from this long-standing customer. In addition, a major automobile manufacturer migrated to the cloud with Vertex as part of its SAP ECC the S4 HANA cloud transformation journey. The customer also expanded its entitlement so we could consolidate additional operations into its Vertex contract as part of the project. The result was 7 figures of additional annual revenue with this long-standing customer. Also during the corner, 1 of our first e-invoicing customers committed to expand country coverage with Vertex. This customer started with Vertex in 4 countries and after a successful launch has now expanded to several additional countries, driving nearly $100,000 of new annual revenue. As I noted earlier, we're especially excited that this is an early proof point that e- invoicing will be an ongoing land-and-expand motion for Vertex. The new customers we acquired in the early stages will provide a strong foundation for significant future revenue opportunities. A leading global aerospace and defense manufacturers selected Vertex for e-invoicing, as I noted earlier, this was driven by the upcoming Belgian mandate, which will kick off in January. However, we expect additional e-invoicing opportunities with this long- standing customer. Turning to new logos. We won a customer in the food delivery industry after an intensely competitive bake-off with an incumbent competitor. The customer was unhappy with the competitors per transaction-based pricing, which led to extremely high costs for this high- volume business. Vertex's revenue-based pricing model provided them with the predictability, consistency and stability of costs. This competitive takeaway included sales and value-added tax calculation as well as several Vertex tools. The customer also signed on to be 1 of our early adopters for smart categorization. This 6-figure deal, which was in the Shopify ecosystem was facilitated by our partner, KPMG. In Europe, we won a new mid 6-figure customer in the gaming industry when an Oracle Cloud transformation led them to explore third-party indirect tax solutions. This new customer relationship included VAT, consumer use tax and sales tax calculation as well as address cleansing. A manufacturer of popular collectible toys switched to Vertex as part of a global Microsoft D365 cloud transformation. The result was mid-6 figures of new annual revenue. A customer was previously using a competitor in the U.S. and native ERP tax solutions in Europe but was getting incorrect tax answers due to a flawed integration. In addition, the competitors' support to resolve these issues was unsatisfactory. The implementation, which was led by our partner, DMA, included an e-commerce component with connectivity to the company's instance of BigCommerce for online sales. Our global tax content coverage was also a significant differentiator as the customer had aggressive international expansion plans. Finally, a major public utility selected Vertex to displace an incumbent competitor as part of an Oracle cloud transformation. This 3-year mid-6- figure deal included sales and consumer use tax calculation on Oracle Cloud along with the exemption certificate manager and other tools. Vertex Consulting was also engaged by our partner, PwC, to assist with the implementation. Throughout our 5 years as a public company, we've built a reputation for under promising and over delivering. The second quarter fell below that standard, and we take that seriously. We're taking clear focused steps in the short term to ensure we're executing at the level we expect of ourselves and that of our investors, while also remaining steadfastly focused on the long term and the great market opportunity we have in front of us. John will now take us through the financials.
