Good morning, everyone, and thank you for joining us. Q3 was another strong quarter for ATI, delivering results ahead of our projections, advancing our long-term strategy and strengthening our leadership in aerospace and defense. Our teams continue to perform at a high level, meeting growing customer needs and driving sustained value. Let's start with a quick overview of our Q3 results. Revenue was up 7% year-over-year, once again exceeding $1.1 billion. Adjusted EPS was $0.85, $0.10 above the high end of our projected range. Adjusted EBITDA totaled $225 million. Excluding approximately $10 million related to the sale of oil and gas rights, $215 million of adjusted EBITDA exceeded the high end of our guidance by $5 million. Adjusted EBITDA margin exceeded 20%, our highest since the pandemic and almost double 2019's margin. Both segments delivered excellent profitability. Our High Performance Materials & Components segment margins were above 24%. And Advanced Alloys & Solutions segment above 17%, driven by strong pricing, mix and increasing aerospace and defense content. Cash generated from operations year-to-date reached $299 million, a $273 million improvement from last year. We also returned $150 million to shareholders this quarter through share repurchases, with $120 million remaining under our current authorization. Given this performance and our outlook for Q4, we are raising our full year guidance across the board. Adjusted EBITDA for 2025 now forecast between $848 million and $858 million, a $28 million increase at the midpoint. Adjusted free cash flow now forecast between $330 million and $370 million, a $40 million increase at the midpoint. Don will share more details on this in a moment. With 1 quarter left in 2025, I want to highlight three key themes driving ATI's continued momentum and future outlook. First, we have strong demand in our core markets, with aerospace and defense leading the way. Total A&D revenue rose 21% year-over-year in the third quarter, fueled by record defense performance and sustained demand in jet engines. This quarter, A&D reached an all-time high of 70% of total revenue, marking an important milestone in our strategy. Long-term agreements and differentiated materials are supporting consistent growth through 2026 and beyond. I'll detail what I see in these markets. Our largest market, jet engines, now 39% of total revenue, grew 19% year-over-year in Q3, with MRO representing about 50% of total engine sales. Next-generation programs such as LEAP and GTF continued to accelerate with strong production and aftermarket demand. You probably heard OEMs make those forecasts in their recent earnings calls. This sustained momentum supports long-term growth for ATI's proprietary alloys and forged turbine discs. Our order book extends into the mid-2027, underscoring tight supply and the strength of our customer partnerships. As a priority supplier, we've gained additional share in content where others have faced execution challenges while maintaining pricing that reflects the value of our capabilities. Looking ahead, we expect Q4 jet engine revenue growth in the high single to low double digits. For the full year, jet engine growth is expected to exceed 20%. With multi-decade customer agreements and increasing platform demand, ATI is well positioned for continued share gains and profitable growth through this aerospace cycle. Airframe sales grew 9% year-over-year and 3% year-to-date this quarter, supported by the ongoing ramp in Boeing and Airbus production and timing of customer orders. Boeing's production rate increase of 42 per month on the 737 and Airbus' A320 target of 75 per month by 2027 signal healthy sustained demand. We expect Q4 airframe revenues to finish modestly above 2024 levels as airframers adjust their inventory to production needs. ATI's expanded titanium capacity and advanced processing capabilities are driving share gains and improved pricing across OEM platforms, enhancing our mix of higher-value structural components and supporting continued margin expansion. Next year, we anticipate high single-digit growth in airframe revenues, driven by steady production ramps, increased ATI content and favorable pricing under new long-term contracts that start at the beginning of 2026. Beyond 2026, as build rates rise, ATI's airframe business is poised to grow faster than overall industry volumes, reflecting our differentiated titanium portfolio and deep customer alignment. Defense markets remain exceptionally strong. Revenue increased 51% year-over-year and 36% sequentially, reflecting broad-based strength across naval nuclear, rotary craft, missile and armored vehicle programs. Our diversified product base benefits from both U.S. and allied spending growth. We continue to qualify our new programs entering early production. ATI's defense business has now delivered 3 consecutive years of double-digit growth, outpacing defense spending. Highlights this quarter include being named Supplier of the Year by General Dynamics U.K., underscoring customer trust and ATI's performance and reliable delivery. Missile and propulsion programs are expanding rapidly. ATI's advanced materials are increasingly specified in [ THAAD ] and PAC-3 systems, where production is accelerating to meet recapitalization demand. We're also supporting emerging initiatives like Golden Dome, positioning ATI for above-market growth into the next decade. Emergent naval nuclear also contributed meaningfully to Q3 performance, showcasing the resilience and scale of our defense portfolio. With expanding qualifications, multiyear visibility and growing international participation, defense is set for continued record performance as modernization and replenishment programs ramp worldwide. Bottom line, A&D remains the foundation of ATI's growth. My second key theme, operational excellence and disciplined execution are the backbone of our performance. This quarter, the team delivered strong productivity gains. Across ATI, we're delivering what we call the triple threat: higher uptime, improved first pass yield and expanding manufacturing capabilities. We have examples across the company. In our nickel remelt operations, output increased by double digits. In the isothermal flow path, heat treat cycle time improved 3x. Accelerated throughput is lower in cost and freeing capacity for our crucial jet engine products. At our Specialty Materials business, we also expanded powder atomization capacity by over 25%, improving yield and quality. We expect to see the benefits of this improvement in our first half 2026 shipments. Our Specialty Rolled product business achieved a new record for monthly coil shipments, another demonstration of increased throughput and efficiency. Specialty Alloys and Components unlocked more than 20% additional capacity in the zirconium sponge process. This was accomplished through standard work and maintenance optimization requiring minimal capital investment. As a reminder, ATI is the leading producer of high-purity zirconium at scale in the Western world. This material is important to national defense, energy and aerospace. It's a small but highly profitable part of our business today, with significant growth potential ahead. Collectively, these initiatives have expanded available capacity by roughly 10%, with the greatest impact in our differentiated [ mode ] products and contribute to our margin gains. These are not just operational wins, they enhance reliability, increase asset utilization and drive long-term earnings growth. By securing additional customer qualifications on new equipment and products, we're building the foundation for ATI's next chapter of performance and profitability. My third theme this quarter, our strategy and investments continue to drive long-term value. Our strategy is working. With 70% of revenue now coming from aerospace and defense, ATI is firmly focused on our most differentiated, high-value materials and markets. Our nickel investment expands differentiated capacity at the top of the value chain. You'll recall, we're the sole-source producer for 5 of the 7 most advanced super alloys in the jet engine. Before we decide to invest, each project undergoes a disciplined review process, requiring projected internal rates of return above 30% and clear alignment with long-term customer contracts. In many cases, our customers are funding alongside us, reinforcing shared confidence in the demand outlook and guaranteeing needed capacity is in place for the future. We'll continue deploying capital with focus and discipline, prioritizing differentiated products, high-return investments and strategic partnerships that sustain ATI's leadership and create long-term value. I've been recently asked by a few investors whether investing in nickel melt capacity will negatively impact our pricing. The short answer is no. Our focus is on our most differentiated products. This is about expanding the competitive moat while supporting the engine ramp and our customers' ambitious growth targets. In summary, strong aerospace and defense demand, a relentless focus on operational excellence and a strategy that's creating long-term value resulted in Q3 being ATI's strongest quarter of the year. We're well positioned to extend our momentum to finish 2025 strong. And with that, I'll turn it over to Don.
