Thank you, Scott, and good morning, everyone. We appreciate you joining us today. NetScout delivered strong fiscal year 2026 top and bottom line results, driven by growth across both our Cybersecurity and Service Assurance offerings. Our performance in the fiscal year helped us achieve the key strategic objectives we laid out a year ago, including accelerating product innovation, driving annual revenue growth and expanding margins. We also strengthened our innovation engine through the introduction of differentiated capability across the portfolio, including AI-ready smart data, expanded observability, enhanced edge visibility and adaptive threat protection. We accomplished this in what continues to be a dynamic operating environment, underscoring the strength of our strategy and the consistency of our execution. These results have further reinforced our financial foundation and position NetScout to drive continued innovation, revenue growth and margin improvement in fiscal year 2027. At the same time, we believe market trends across AI, observability and network security are expanding our opportunity set and creating additional revenue for long-term value creation. With that context, let me turn to Slide #6 for a brief review of our fourth quarter and full fiscal year 2026 financial performance for the period ended March 31, 2026. For the fourth quarter, total revenue was approximately $203 million compared with $205 million for the same period last fiscal year, which was in line with our expectations given the shift in customer order timing to the prior quarter as we discussed on our Q3 earnings call. Diluted earnings per share was $0.52, consistent with the same period last fiscal year. For the full fiscal year, which is more representative of the business and the underlying market trends, revenue increased by 4.5% to approximately $860 million, driven by growth in both our Cybersecurity and Service Assurance offerings. We expanded both our gross and operating margins year-over-year and delivered nearly 12% growth in diluted earnings per share at $2.48, exceeding the high end of our guidance range. Now let's turn to Slide #7 for some perspective on our business and some market insights. Starting with a review of our service assurance offerings. The revenue for the full fiscal year increased approximately 3% year-over-year, driven by growth in the enterprise customer vertical with strong contributions from both federal and nonfederal government-related spending. Our Enterprise customers continue to rely on our Service Assurance solutions to advance their digital transformation initiatives. In turn, we are investing in innovation, particularly with respect to observability and AI and to help our customers drive greater efficiency, reduce risk and accelerate troubleshooting and lower costs. An example of this innovation during the year is our Omnis Sensor and Omnis streamer, which work together as an integrated AIOps solution that transforms high-fidelity network packet data into actionable intelligence. Also, our sensor and streamer products include Agentic AI interfaces that enable efficient and cost-effective integration with multi-vendor AI solutions, which facilitate automation and reduces total cost of ownership for our customers. Among our Carrier Service Provider customers, we continue to see measured 5G investment as they balance build-outs with monetization, and we expect this to continue into our fiscal year 2027. At the same time, emerging opportunities such as fixed wireless access, 5G network slicing and AIOps initiative have the potential to drive revenue and cost efficiency for a Communication Service Provider. We believe NETScout is well positioned to support this transition. Our 5G observability solution provides end-to-end visibility for 5G stand-alone slices to support high-performance services such as immersive gaming and large-scale sporting events as well as mission-critical application and services. Moving to our Cybersecurity offerings. Revenue for the full fiscal year increased approximately 8%, with growth across both our Enterprise and Service Provider verticals. Cybersecurity continues to grow faster than the company average and is an increasingly important driver of our long-term revenue growth and margin expansion. Our latest DDoS Threat Intelligence report, which was released in March 2026, assesses the current global threat environment, including newer AI-powered attacks. Foundational services such as DNS and NTP remain under persistent pressure and recent botnet attacks on government, financial and transportation infrastructure show how quickly threat actors can disrupt critical services with either legacy tools or by using AI to increase the scale and sophistication of their attacks. Large coordinated attacks are outpacing traditional defenses and organizations are increasingly turning to automated intelligent protection to keep up. NetScout is well positioned to help customers protect their digital services. Many of our newest innovations support distributed detection and mitigation solutions to provide a more robust and resilient adaptive DDoS protection environment. Additionally, as noted in our earnings release, we just completed a tuck-in acquisition of the assets of DigiCert Incorporation's DDoS protection business that brings the back-end infrastructure of our Arbor Cloud network to fully in-house. We believe this transaction provides us with a greater control of the platform and a clearer path to scaling cloud-based services over time while providing immediate incremental recurring revenue in the cloud DDoS space. Before touching on some of our recent customer wins, I would like to briefly discuss AI and what we believe this new era would mean for NetScout over time. We believe AI will create additional opportunities for both Service Assurance and Cybersecurity by amplifying the need for network visibility and protection. As networks grow more complex and cyber threats increasingly leverage AI tools, we believe the need for adaptive real-time visibility and intelligence protection will continue to rise. These dynamics play directly to NetScout's strengths. We have long been recognized for our packet level approach to network detection, investigation and response. Now our patented deep-packet inspection and metadata aggregation capabilities can generate complex, high fidelity, AI-ready smart data at scale that is purpose-built for advanced analytics like never before. More importantly, we are not competing with foundational AI models. Instead, we are leveraging our differentiated data and domain expertise to enable automation that integrates into our customers' broader observability and AI workflows, helping to enhance visibility and operationalize AI within those environments. From a financial perspective, we believe AI advancement could reinforce the durability of both our cybersecurity and service assurance businesses by supporting upgrade cycles and expanding use cases across our installed base. Taken together, we view AI as a promising opportunity that enhances the value of what we already do best and extends our relevance within customers' critical infrastructures over the long term as they develop and implement their broader AI strategies and initiatives. Turning to customer wins, both Service Assurance and Cybersecurity continue to gain traction. In addition to new customers, we continue to secure a significant amount of repeat business from loyal customers buying new solutions and upgrades along with maintenance services. Two wins from the fourth quarter were: A mid-seven-figure deal with a large European telecom that has been a longtime Cybersecurity and Service Assurance customer. They upgraded their DDoS protection with our Adaptive DDoS offering and our Distributed Threat Mitigation System to enhance their cyber protection. Our adaptive's DDoS mitigates all types of multi-vector attacks before they can impact critical services, while DMS provides enterprise-level protection across both cloud and edge environments with physical and virtual platforms and multiple usage configurations. This client also values our subscription model, which includes support and maintenance and a flexible scale-up and scale-down approach to minimize license wastage. A second deal in the low-seven- figures was with a new customer that is a global leader in chip manufacturing for a variety of industries, including automotive, mobile communications and data centers. This contract included our engineered solution to maintain traffic visibility and address system reliability issues across the network that spans multiple countries. They chose NetScout because of our reputation and ability to provide the critical solutions required to manage the complex interdependency of their networks and applications. With that, let's move to Slide #8 to review our outlook. In fiscal year 2026, we returned the business to revenue growth, improved margins, expanded profitability, delivered strong free cash flows and continue to advance our product capability across both Cybersecurity and Service Assurance. Looking ahead, we are excited about the year in front of us and are leaning into this momentum. We see significant opportunities over the long term to leverage NetScout's deep expertise in cybersecurity and network observability together with our AI-ready data platform to help customers advance their AI and digital transformation initiatives and to manage an increasingly complex digital environment where network performance, availability and security are mission-critical. We believe we are well positioned to drive profitable growth, generate strong free cash flow and enhance long-term shareholder value. These growth dynamics are reflected in our fiscal year 2027 outlook, which Tony will review during his remarks. While we remain mindful of the macro environment, ongoing carrier spending discipline and demand trends across both enterprise and service provider customers, our priorities remains clear. We aim to drive sustained revenue growth by executing against a healthy pipeline with particular emphasis on Cybersecurity and enterprise-led Service Assurance. At the same time, we'll continue to invest in innovation across AI, observability and DDoS protection as well as maintain a disciplined focus on cost management and a balanced capital allocation strategy. We are energized by what lies ahead and look forward to updating you on our progress throughout the year. With that, I will turn the call over to Tony for a review of our financial performance and our outlook for fiscal year 2026 -- 2027.
