Thanks, Mark, and good afternoon to everyone on the line. In the third quarter, we delivered solid results with revenue of $1.12 billion, adjusted EBITDA of $393 million and a 35% adjusted EBITDA margin. Importantly, we are beginning to make progress on our capital efficiency and cash generation initiatives. I am incredibly thankful for the hard work of the Viasat team that delivered these results. We positioned ourselves to close out the year strongly and with a quarter to go, we have a high degree of confidence in our fiscal 2025 guidance. My segment has grown in a few months that I've been here. Viasat continues to win in key markets, including defense and aviation and build great franchises with durable competitive moats, while demonstrating financial and strategic discipline. The path ahead has become clear. There are three key priorities that we are focused on: first, building our franchises, earnings power and customer lifetime value while investing with discipline in our future. By way of example, every 10 or so commercial aircraft we install is worth roughly $4 million to $5 million in discounted lifetime EBITDA contribution, which highlights the future value of the 1,570 aircraft in our aviation backlog. Similarly, 100 maritime vessels represent a lifetime adjusted EBITDA contribution of about $3 million. Our second priority, reducing our leverage, which we believe is pressuring our debt and equity. We are not ready to share end-state leverage targets yet, but it's clear our debt level needs to be substantially lower. So paying down debt is our top priority for capital allocation. And finally, generating free cash flow. We are examining a variety of mechanisms to accelerate deleveraging. However, generating free cash flow is the best means of sustainably achieving that objective. And the highest quality path of free cash flow is continued franchise development that I noted. We are focused on delivering that. We are now working collectively to get organized for execution in fiscal 2026 and to ensure that it will be a true and sustained turning point on all three of these fronts. A big driver of my excitement comes from the response our Viasat team has had in getting this work done and the progress we've made over the last few months and coming together to solve problems. I'll speak to CapEx prioritization, which is a great example of that in a few minutes. Here are some recent developments that excite me on the longer-term development of our franchise. As we focused on optimizing our capacity in the time before ViaSat-3 launches, we've uncovered a variety of opportunities to enhance our coverage, capacity and the performance we deliver to our customers. Mark mentioned this idea in his remarks. Two good intangible examples are first and reconfiguring our ground network to allow cross-roaming between the ViaSat/Inmarsat networks. Among other things, we should see a meaningful gain in the bandwidth we can offer our customers in business aviation at virtually no incremental cost to us and with no collateral impact on our existing customer franchises. Second, we have an evolved path to secure targeted capacity from third parties that will reinforce some important coverage areas and enable more growth with better outcomes for our customers. When ViaSat-3 Flights 2 and 3 enter commercial services, these purchases will offer continued and complementary support in some critical parts of our network. The changes reduced CapEx, but more importantly, enhance our ability to serve our broad and growing customer base for the long-term. Fiscal 2025 continues to see expansion of our multi-band, multi-orbit positions across the global defense market with opportunities and applications in the U.S. and globally. In the third quarter, government SATCOM won new awards on recompetes and captured a new line-fit position to deliver dual band Global Arrow terminals for the Embraer C-390 multi-mission airlifter. Viasat's multi-band, multi-orbit, multi-network terminals will be integrated into the aircraft, leveraging our decade-plus development of these hardware and networking capabilities that enable new networks to be easily integrated. Customers across our portfolio are increasingly interested in multi-orbit solutions and our growing capabilities in that area will serve us well in the future. There are too many great stories in our DAT business to cover on this call, but let me highlight one part, our encryption business. Our KG-142 products have continued to see record awards in fiscal 2025 with $135 million in the fiscal year-to-date through the third quarter. These awards are also the result of long-term investments beginning 10 years ago to develop and certify this current family of crypto products. The revenues are further expanding our installed base of products as we prepare to participate and compete for the next-generation encryption market, where we'll leverage our current capabilities, along with new technologies to provide high assurance encryption from the tactical edge and cloud connectivity while looking to expand in the space. Gearing in on the near-term now, we faced continued challenges that create revenue pressure in our U.S. fixed broadband business as we focus capacity towards meeting the growing demand from our higher-value commercial aviation business. Maritime revenue was also down $2 million sequentially due to incremental ARPU pressure and continued L-band migration ahead of our wider rollout of NexusWave. We expect the rollout of NexusWave and the entry of ViaSat-3 Flight 2 into service will help turn these trends around beginning late in fiscal 2026. Meanwhile, we are building earnings power in our other franchises. In aviation, our wins are translating into more aircraft in service and new awards are sufficient to leave us with a growing backlog of future installs. Aviation service revenue increased approximately 12% year-over-year and we ended the quarter with 3,950 aircraft in service, up about 130 sequentially and a contracted backlog of approximately 1,570 aircraft, up about 60 sequentially. While we are confident in the growth outlook and the trajectory for Aviation, our near-term results continue to be impacted by a slow recovery of OEM deliveries, as a result, we believe we will be a little bit below our prior target of 4,200 aircraft in service by the end of the fiscal year. Further diversifying our earnings power into non-transmission, our sponsorship monetization, while nascent, is great for our customers and is beginning to generate high-value revenue with exciting future potential. Fiscal 2026 is an important year for this business as we prepare to scale and are better able to size future market opportunities. Our Defense and Advanced Technologies segment is a standout again this quarter with all businesses growing well. Importantly, the leading indicators continue to signal strong growth in the year ahead. Secular trends are favorable, product cycles and white space product launches are supportive and awards are up 49%, backlog up 26% and sole-source IDQ is up 13% year-over-year. On the capital side, as we approach our long-term planning process in December, we ran a prioritization exercise across the company to drive real focus on the most essential work for fiscal 2026 and a few things that emerge from that process led to opportunities to better focus even in the remainder of this fiscal year, which helped to reduce some spend. Also, as noted last quarter, we've been pushing hard to refine timing of our capital spend, advancing customer critical items and deferring anything not critical to defer both capital spend and operating expense impacts. As we undertook this process, we found several opportunities to purposely move spend out, reduce some spend altogether and/or establish a more refined view of when we might hit key milestones on the space and ground side. The combined impact of these efforts was a large reduction in satellite spend and a reduction of projected growth in our run rate spend on things like software and other CapEx for a total of a $200 million reduction from the low end of prior guidance. At the same time, we were able to hold future spend flat, so our free cash flow will benefit from all of that reduction. Now I'll cover two topics in more detail, financial performance during the third quarter and our outlook for the fourth quarter and fiscal 2026. Let's begin with the financial results. All of my statements in this section will reference the third quarter of fiscal 2025 and the prior year period, the third quarter of fiscal 2024. Awards were $1.08 billion, led by our Defense and Advanced Technologies segment and Aviation Connectivity. Backlog was $3.5 billion, down $181 million. Backlog declined due to the removal of the Energy Services System Integration backlog with the sale of that business, along with declining subscribers in our U.S. fixed broadband business and fewer long-term contracts in that business. Revenue was $1.12 billion, essentially flat compared to the prior year quarter, reflecting declines in fixed broadband and product revenue within Communication Services, offset by strong growth in Aviation and Information Security, Space and Mission systems and tactical networking in our Defense and Advanced Technologies segment. Net loss of $158 million increased from the net loss of $124 million a year ago principally due to the $97 million non-cash loss on extinguishment of the Inmarsat 2026 senior secured notes as we refinanced the debt to extend maturity. Adjusted EBITDA was $393 million, an increase of 3%, primarily driven by growth in our DAT segment, reflecting $15 million of higher than anticipated tactical data radio licensing benefits, partially offset by fixed broadband and maritime within Communication Services. Operating cash flow was $219 million, up more than 60% despite absorbing approximately $30 million related to facility rationalization outflows. The improvement was primarily driven by decreased working capital and lower cash taxes. CapEx was $253 million, down 40% year-over-year from $421 million. We also collected an additional $42.5 million of satellite insurance proceeds and have now cumulatively received about 97% of an anticipated $770 million. Please note, collection of these proceeds has no impact on our free cash flow calculation. Consistent with our ongoing portfolio review, we completed the sale of the Energy Services System Integration business, which was included in fixed services and other within the Communication Services segment. The business generated approximately $50 million in revenue annually, but had minimal strategic synergies with our core businesses. Finally, net leverage was slightly lower year-over-year and slightly higher sequentially at about 3.7x trailing 12 months adjusted EBITDA. The sequential increase is due to the commencement of GX-10A/B finance leases, which increased our debt by about $150 million. Now let's turn to some segment highlights. And again, in this section, all references will be to the third quarter of fiscal 2025 compared to the third quarter of fiscal 2024. In Communication Services, revenue was $820 million, down 6%, reflecting the anticipated decline in our U.S. fixed broadband services and products, partially offset by strong growth in aviation and government SATCOM. Aviation grew 12%, led by a 13% increase in commercial aircraft in service. Our government SATCOM business grew revenue 4% as strong demand for connectivity remained a top budget priority. Maritime revenue declined 8% as legacy L-band offerings continued to decline, and we see incremental broadband ARPU pressure. Fixed services and other revenue was down 21% as U.S. fixed broadband subscribers continue to decline as expected. Those revenue impacts drove EBITDA to $330 million, down just 1% year-over-year. Turning to Defense and Advanced Technologies, or DAT, performance. Awards of $327 million increased approximately 49% versus $220 million. Revenue was $303 million, up 20% compared to $254 million. We saw broad strength across the segment, including information security, space and mission systems and tactical networking. Info sec and cyber defense, space and mission systems product revenues were up 24% and 19%, respectively, driven by strong product sales. Similar to the last two quarters, the tactical networking business line benefited by about $20 million in revenue and $15 million in adjusted EBITDA from the activation of certain product upgrades along with new radio shipments. Once activated, we recognized IP licensing revenue on these products that have been sold in prior periods. Activations of new capabilities from prior period shipments are difficult to forecast, and we project future new shipment license revenues at lower levels than were recognized year-to-date. Defense and Advanced Technologies adjusted EBITDA was $64 million, up 27% compared to $50 million, reflecting the strong revenue growth across the segment. Overall, we continue to make good progress against our fiscal 2025 plan, driving solid growth in cash from operations while CapEx continues to come in lower than expected. As a result, Q3 and year-to-date cash burn has been lower than previously anticipated. Now let me turn to our outlook. Challenges continue, but the Viasat team is rising to meet those challenges. We continue to expect fiscal 2025 revenue to be flat to slightly up year-over-year, with adjusted EBITDA growth in the mid-single digits. Given results thus far, our confidence in achieving our fiscal 2025 EBITDA guidance has clearly increased, and we've provided additional segment-level detail in the Outlook section of our shareholder letter and slides. We've talked a lot about CapEx today. With some of all the efforts I've mentioned, leaves us with an expectation that fiscal 2025 CapEx will be $200 million lower than the low end of our last fiscal 2025 guidance at approximately $1.1 billion. We recently completed our multiyear strategic plan and are now mobilizing to refine our fiscal 2026 outlook and resource the initiative that will support it. In addition to the challenges we face as we exit fiscal 2025, we will have a remaining $250 million of CapEx and about $80 million of recurring OpEx related to the build of our ViaSat-3 space and ground assets that won't generate material incremental revenue until late in the year. For fiscal 2026, we expect year-over-year revenue growth and modest adjusted EBITDA growth. Despite the $200 million reduction of fiscal 2025 CapEx, expected 2026 CapEx is essentially flat to prior implied guidance at about $1.3 billion. With the timing shifts we now anticipate around CapEx, we believe free cash flow inflection will occur in the second half of our fiscal year as we get beyond the elevated CapEx related to the development of our ViaSat-3 space and ground networks. However, for the sake of clarity, with adjusted EBITDA essentially unchanged and CapEx $200 million lower than the midpoint of our prior guidance, our outlook for cash generation across fiscal 2025 and 2026 combined has improved by about $200 million. We are making progress, but we know we have a lot more work to do to further improve cash generation. In closing, the quarter's operational performance was good. We are capturing our share of large and growing markets and remain focused on improving operational productivity and capital efficiency. Fiscal 2026 is a very important year for us, one where NexusWave and the launch of our ViaSat-3 satellites will help turn the trends in maritime and fixed broadband around. While at the same time, we continue to build our earnings power in aviation, government SATCOM and DAT, leveraging the backlogs our teams continue to build. The Viasat team is up to these challenges, and I'm honored to be part of this as we work tirelessly to deliver improving outcomes for our people, our customers and for you, our owners. With that, I'd like to hand the call back over to Mark.
