Many thanks, Angela. Good morning, everyone. Thank you for joining us to discuss our full-year results. I hope to see many of you later today at our building our energy future event for a deep dive on major capital projects we are delivering across the UK and the Northeast U.S. As ever, I'm here with Andy Agg. And once we've been through our respective presentations, we'll be happy to answer your questions. Last May, we announced a refined strategy focused on pure-play networks. We also set out a new five-year financial framework and our plans for £60 billion of capital investment. This will drive asset growth around 10% per annum and underlying earnings per share growth of 6% to 8%, whilst maintaining a strong balance sheet and delivering an inflation-protected dividend. Alongside this, we set that our comprehensive financing strategy, including our £7 billion equity raise, providing clarity over our funding to at least 2031. In the first year of the five-year framework, we've accomplished a huge amount despite the turbulent economic and geopolitical environment. We've delivered record capital investment of £9.8 billion, in line with our plan, and 20% higher than last year. This reflects the scale of the activity across all of our regulated businesses, including significant progress within our ASTI portfolio, where all six of our Wave 1 projects are now under construction, a step-up in asset health and network reinforcement in Electricity Distribution, over 350 miles of gas mains replacement across Massachusetts and New York and good progress with our Smart Path Connect project in U.S. Electricity Transmission. We've also secured the supply chain and delivery mechanisms for more than two-thirds of our £60 billion of capital investment. For ASTI, this includes contracts with the delivery of 12 onshore and two offshore projects, while also making good progress on Eastern Green Links 3 and 4 and Sea Link. And in New York, we've made further progress with our $4 billion Upstate Upgrade, awarding contracts for the first phase as well as the engineering works for Phase 2. The policy and regulatory agenda on both sides of the Atlantic has also continued to move forward, further enhancing visibility on our investment plan. In the UK, the government published its Clean Power Action Plan in December, and Ofgem published its decision on connections reform last month, which embeds, is it ready and is it needed criteria into the connections process. This will deliver a rationalized queue of projects aligned with the Clean Power Plan and clarify the specific investments in locations required in the outer years of T3. New legislation on planning reforms was also introduced in March, which aims to reduce the time it takes to deliver infrastructure projects. Whilst the reforms will be more impactful in the 2030s, there are important measures in the bill that have the potential to further derisk our ASTI projects. In the U.S., we refreshed all three of our New York rate plans and agreed new rates for our Electricity Distribution business in Massachusetts over the last year. Altogether, this means that we've now agreed over 70% of our U.S. investment with regulators over our five-year frame. We also expect to receive approval for our electricity sector modernization plan in Massachusetts where we filed through up to $2 billion of capital investment over the next five years to help deliver the state's clean energy policy. So the combination of these firm foundations of our resilient business model, which provides strong regulatory protections from macroeconomic uncertainty and no significant exposure to energy prices or merchant risk means that we are very well positioned and hugely confident in our ability to deliver our £60 billion investment program. We will have much more to share on capital delivery at our investor event this afternoon, where we will showcase the sheer scale of our Electricity Transmission projects and how we've transformed the way we are delivering them. So turning now to some of the key highlights for the year. We've delivered a strong performance, with underlying operating profit increased 12% to £5.4 billion at constant currency. This reflects robust operational performance as a result of increased regulated revenues and flat controllable costs achieved through our focus on agreeing the right regulatory frameworks and efficient delivery. Underlying earnings per share was slightly ahead of guidance at 73.3p and up 2%, reflecting the impact of a higher share count following the rights issue. A record £9.8 billion of capital investment helped to drive regulated asset growth of 10.5%. And in accordance with our policy to grow the dividend in line with the U.K. CPIH, the Board has declared a final dividend of 30.88p per share. This takes the total dividend for the year to 46.72p, an increase of 3.21% on last year's rebased dividend. Moving next to reliability and safety. Reliabilities remain strong across our UK and U.S. networks despite severe weather events across our jurisdictions. An example of this is Storm Darragh last December, a once-in-a-decade storm that hit our UK electricity distribution networks, causing significant damage across the Southwest, South Wales and West Midlands. Our teams were tirelessly around the clock restoring power to 95% of customers within 48 hours. Last week, the NESO published its interim report investigating the outage following the fire at our North Hyde substation in March. We welcome the report, which establishes a time line and sequence of events, and outlines further steps required to deliver the final report in June. On safety, our lost time injury frequency rate was 0.1%, in line with our group target. As our workload increases, we continue to invest heavily in attracting, developing and retaining a qualified and competent workforce with robust training programs built around the culture of safety. We've also set protocols for our contractors so that high safety standards are maintained right across the workforce. Turning to our operating performance across the group, starting with the UK Electricity Transmission. Investment increased by 57% to £3 billion, reflecting the ramp-up in the first wave of six ASTI projects, major substation upgrades and a further 4 gigawatts of generation being connected to the network. This included the UK's largest battery storage unit at Lakeside in North Yorkshire and a 1.2 gigawatt offshore wind farm in Dogger Bank. The business delivered a return on equity of 8.3%, outperforming its allowed return by 100 basis points. Turning to regulatory developments. In December, we submitted our £35 billion RIIO-T3 business plan, representing the most significant investment in the UK's Electricity Transmission network in a generation. This ambitious plan will nearly double the power that can flow across the country, directly connecting 35 gigawatts of generation and 19 gigawatts of demand and create optionality for a further 26 gigawatts, all whilst maintaining world-class levels of reliability. Our submission also included clear evidence of the need for an investable financial framework, including a real 6.3% allowed cost of equity, appropriate levels of cash generation and incentive mechanisms that will deliver benefits to both networks and consumers. Under our proposals, we expect our investment plans to avoid constraint costs of around £12 billion over the price control period, offsetting the impact of investment to customer bills. In addition, we are also pleased to see Ofgem's decision on the advanced procurement mechanism. This will provide funding for transmission owners to secure supply chain capacity, covering items like switchgear and transformers. This builds on the approach Ofgem adopted under the ASTI regime, and we plan to utilize the framework from the middle of this year. Finally, on policy developments. In addition to the connections reform I mentioned earlier, the government published its planning and infrastructure bill. The bill includes a number of proposals that are important to us, including giving certain projects the flexibility to choose the type of consenting regime used and providing opportunities to accelerate the consenting process. The bill also includes proposals intended to increase public acceptability of Electricity Transmission projects, alongside guidance for wider community benefits. Moving to strategic infrastructure. This will get a lot of focus this afternoon, but to summarize, we now have the Great Grid Partnership up and running, the HVDC framework agreement in place, the supply chain secured for all 12 onshore projects, all Wave 1 projects under construction, and we've continued to build our internal capabilities and the workforce now stands at over 1,000 employees. So in the last year, we put the platform in place and delivery is well underway. Carl and his team will provide a lot more detail on our progress later today. Turning to UK Electricity Distribution. Capital investment increased by 14% to £1.4 billion, driven by increased spending on asset health, network reinforcement and connecting nearly 600 megawatts of renewable generation. The business achieved a return on equity of 7.9%. And whilst this reflects the benefit of our synergy savings program, it was heavily impacted by costs from Storm Darragh as well as lower-than-anticipated allowances from Ofgem's real price effects mechanism that haven't matched what we were expecting when the price control was agreed. We are working hard to address the ongoing headwind and expect performance to improve over the remainder of the price control period. This year, we also made good progress in developing our role as this distribution system operator, or DSO, including our leading role in the development of flexibility markets. We now operate the largest market across all DSOs, allowing us to avoid over 200 gigawatt hours of renewable generation curtailment, lowering costs for consumers. On the regulatory front, Ofgem published the ED3 framework decision at the end of April, which gives us an early indication of their thinking in the next price control period, and is the starting point for the development of the sector-specific methodology. And as I mentioned earlier, we were pleased to see Ofgem's decision on connections reform. Electricity Distribution has been playing a leading role in driving forward these reforms. And over the last year, we've been able to implement the industry's technical limits initiative, accelerating the connection office dates on around 3 gigawatts of distributed generation and removed over 4 gigawatts of capacity from connections queues. Turning to the U.S. Our investment in New York increased by 24% to £3.3 billion. This reflects a further 218 miles of gas mains replacement and a continued ramp-up in our $4 billion Upstate Upgrade program, including the reinforcement and upgrade works as part of CLCPA Phase 1 and continued strong progress on Smart Path Connect, where we are rebuilding over 100 miles of transmission lines to connect large-scale renewable generation. Again, we will have much more to say on our Upstate Upgrade program this afternoon. We achieved a return on equity of 8.7%, 94% of allowed and 20 basis points higher than the prior year, reflecting strong performance in our downstate gas businesses in the first year of our new rate plans. On the regulatory front, we reached a joint proposal in April our new rates for Niagara Mohawk business, which includes an improved return on equity of 9.5% and increased CapEx of around 50% over the three years, reflecting our step-up in Electricity Transmission investment and funding to modernize our electric and gas networks and support New York's clean energy goals. The joint proposal also includes provisions to mitigate bill impacts for customers by spreading increases over the three years of the plan and putting in place assistance programs for low-income households. In New England, capital investment increased by 5% to £1.8 billion, reflecting continued gas mains replacement and increased asset condition and grid modernization work across our electric network. Our achieved return on equity was 9.1%, 92% of allowed, benefiting from six months of the new rate agreements in our Massachusetts Electric business. We've also seen a greater focus on affordability in the state, following increased builds from a colder winter. To assist Massachusetts gas customers, we agreed with the regulator to reduce winter gas builds by 10% during March and April, with a deferral to be recovered over the summer. On the regulatory front, in September, the DPU issued its rate case order for our Massachusetts Electric business, approving a five-year plan, with an allowed return of 9.35%. The order includes a new regulatory recovery mechanism that provides timely funding for growing capital investment, an updated performance-based rate mechanism providing inflation protection for operating and maintenance costs and increased allowances to cover the increasing cost of storms. Taken together, these enhanced recovery mechanisms are helping us to earn closer to allowed return. And as I mentioned earlier, the DPU has also approved our electricity sector modernization plan for anticipatory investments to support the decarbonization of our networks. And from a policy perspective, last month, we submitted our Climate Compliance Plan, setting up the strategy to enable our Massachusetts gas network to advance data carbonization goals, whilst maintaining safe, reliable and cost-effective service for our customers. And finally, last November, Governor Healey approved legislation that reforms the permitting process for utility infrastructure. This new approach sets maximum time frames for approvals, capital projects in the state. And finally, in National Grid Ventures, capital investment was 43% lower at £378 million, following completion of the Viking Link to Denmark last year. During the year, we've seen good operational performance across the National Grid Ventures portfolio, including good availability from our interconnector fleet, high levels of availability and utilization at our Long Island generation business and at our Grain LNG terminal, where we are making good progress on the construction of the new tank. On the regulatory front, last month, Ofgem published the decision on the regulatory framework for Offshore Hybrid Assets, an important next step as we continue to develop our LionLink project as a next-generation interconnector. So as I said at the start, we've achieved significant progress across all areas of the business in the last year as we continue to efficiently deliver safe, secure and clean networks for the future. Let me stop there and hand over to Andy to walk you through the numbers before I come back and talk about the priorities for the coming year. Andy?
