RTX Corporation: Every time a commercial airliner pushes back from a gate at O'Hare or LAX, the odds are better than even that a Pratt & Whitney engine is providing the thrust — and that Collins Aerospace avionics are guiding the flight. The resulting entity was immediately among the top five largest defense contractors on the planet, a peer to Lockheed Martin, Boeing, Northrop Grumman, and General Dynamics. The timing of the merger was, in a word, dramatic. Critics asked whether combining a defense electronics firm with a commercial aviation giant made sense at a moment when air travel had essentially ceased. Hayes and his successor, Christopher Calio, answered those critics with time and results. The Patriot missile system, a marquee Raytheon product, became the most publicly recognized weapon in the Russian-Ukrainian war as Ukrainian forces used it to intercept Russian cruise missiles and hypersonic weapons — the kind of real-world validation that no marketing budget could manufacture. Unlike pure defense contractors such as Northrop Grumman or L3Harris Technologies, RTX generates enormous revenue from commercial aerospace. Pratt & Whitney's geared turbofan GTF engine powers the Airbus A320neo family, one of the best-selling commercial jet platforms in history. Collins Aerospace supplies cockpit systems, cabin interiors, and connectivity solutions to virtually every major airframe manufacturer. Its product portfolio spans jet engines, missile systems, radar, avionics, and cybersecurity platforms. Collins is one of the most comprehensive aerospace systems suppliers in the world, providing avionics, flight controls, cabin interiors, connectivity systems, nacelles, actuation systems, and air traffic management solutions. The segment serves both commercial and military customers. On the commercial side, Collins supplies avionics to Airbus, Boeing, Embraer, and Bombardier, and generates significant aftermarket revenue from maintenance, repair, and overhaul (MRO) services. Airlines have little choice but to buy Collins-certified parts for Collins-installed systems — a captive aftermarket dynamic that produces high-margin recurring revenue. On the defense side, Collins supplies electronic warfare systems, military communications, and mission systems to the U.S. Air Force, Navy, and Army, as well as allied defense ministries. The defense aftermarket for Collins is similarly captive and durable. Every GTF engine installed on a commercial jet generates spare parts and service revenue across a 20-to-30-year operational life. The F135 engine program, meanwhile, is essentially an annuity tied to the F-35 production rate and the operational tempo of the approximately 900 F-35s currently flying worldwide. RMD manufactures precision munitions, missile systems, and air defense platforms. The Patriot Advanced Capability-3 (PAC-3) system, the Standard Missile-3 (SM-3), the AIM-9X Sidewinder, the AIM-120 AMRAAM, the Javelin anti-tank missile (co-developed with Lockheed Martin), and the Excalibur precision artillery round are all RMD products. RMD also manufactures the NASAMS (National Advanced Surface-to-Air Missile System) used by Norway and now deployed by Ukraine. The contract structure across the defense segments is critical to understanding RTX's revenue quality. The U.S. Government awards contracts on either a cost-plus or fixed-price basis. Fixed-price contracts allow RTX to capture larger margins if it controls costs effectively but expose it to losses on programs that encounter technical difficulties. RTX, like its peers, has historically preferred cost-plus structures for development-phase programs and fixed-price for mature production programs. From a geographic standpoint, RTX's revenue is roughly 65% domestic and 35% international. International defense sales are governed by Foreign Military Sales (FMS) channels managed by the U.S. Government and Direct Commercial Sales (DCS) conducted directly with foreign governments. This backlog is not merely an accounting construct; it represents years of production schedules already contracted and partially paid for. Collins Aerospace systems are guiding aircraft, managing cabin environments, and ensuring connectivity for millions of travelers. Raytheon missile systems are deployed by the armed forces of more than 40 nations. Raytheon radar and intelligence systems are processing signals intelligence for the most sensitive U.S. Government programs. It is, in the most literal sense, one of the institutional pillars of the American defense-industrial base. The aerospace and defense competitive landscape is an oligopoly defined by a handful of massive, vertically integrated primes and a constellation of specialized mid-tier suppliers. The A320neo family offers both engines; the Boeing 737 MAX uses exclusively CFM LEAP. This duopoly dynamic means Pratt and CFM compete intensely for every new aircraft order, but once an airline selects an engine, the relationship is effectively permanent for that aircraft's operational life. Rolls-Royce, while dominant in wide-body engines, is less directly competitive with Pratt in the narrow-body segment. The Tomahawk cruise missile, now in its Block V iteration, is similarly without domestic competition. The competitive differentiation between Collins and Honeywell often comes down to platform-specific certification history — whichever supplier certified its system on a given aircraft platform first tends to own the aftermarket for that platform indefinitely. These companies are targeting specific capability gaps in autonomous systems, software-defined weapons, and AI-enabled defense applications with agile development approaches that traditional defense primes struggle to match. The Pentagon's Defense Innovation Unit has explicitly worked to channel more contracts to non-traditional defense companies, partially as a competitive spur to the primes. It cannot replicate the integrated propulsion knowledge embedded in Pratt & Whitney's engineering teams. RTX's financial profile in 2024 demonstrated the resilience and breadth of its dual commercial-defense revenue architecture. With a backlog-to-revenue ratio approaching 2.7x, RTX is one of the most visibility-rich large-cap industrial companies in the United States, a characteristic that supports premium valuation multiples relative to more cyclical industrials. In September 2023, RTX disclosed that certain powder metal used in manufacturing high-pressure turbine and compressor disks in older GTF engines did not meet material specifications. RTX negotiated compensation arrangements, further pressuring Pratt & Whitney margins. The episode was a stark reminder that in aerospace, engineering quality failures carry consequences that reverberate across entire aviation systems for years. RTX, like all large defense contractors, faces the inherent difficulty of executing complex fixed-price development contracts on schedule and within budget. Skilled aerospace manufacturing workers — machinists, composite fabricators, engineers specializing in propulsion and guidance systems — are in chronically short supply. Pratt & Whitney engines in the field and Collins Aerospace avionics systems installed in commercial and military aircraft generate captive aftermarket revenue for decades. This structural captivity means that RTX's aftermarket revenue is both predictable and high-margin, insulated from competitive pressure in ways that initial equipment sales are not. RTX holds a vast portfolio of classified defense contracts, maintains secure manufacturing facilities, and employs tens of thousands of personnel with active security clearances. The F135 engine is the sole propulsion system for the F-35. The Patriot system is the primary air defense platform for 17 nations. The aftermarket expansion thesis is the most structurally predictable element. European rearmament following Russia's invasion of Ukraine has already produced significant orders for Patriot interceptors, AMRAAM missiles, and NASAMS systems. RTX is exceptionally well-positioned for this environment given its dominant positions in air defense and precision strike. Collins Aerospace similarly benefits from each new-generation aircraft that enters service. The Raytheon branch of the family tree begins in Cambridge, Massachusetts, in 1922. The Second World War transformed Raytheon from a components manufacturer into a defense electronics powerhouse. The acquisition of Missile Systems Division work from Hughes Aircraft in 1948 positioned Raytheon as a missile systems developer. The Sparrow air-to-air missile, the Hawk surface-to-air missile, and eventually the Patriot missile system all emerged from Raytheon's defense engineering culture. The United Technologies branch of the family tree is equally venerable. The Rockwell Collins thread adds another dimension. The formal merger that created RTX was announced in June 2019 and completed in April 2020.

SK Hynix Inc.: SK hynix began as part of Korea's electronics manufacturing buildout and is now one of the world's most important memory-chip suppliers. Its role in AI infrastructure has expanded because high-bandwidth memory is a bottleneck component for advanced AI accelerators. The latest annual result shows KRW 97.147T of FY2025 revenue and KRW 42.948T of net profit. Q1 2026 was even more dramatic, with KRW 52.576T of revenue in a single quarter. That makes SK hynix one of the clearest examples of how AI demand can reshape semiconductor profit pools.

RTX Corporation and SK Hynix Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between RTX Corporation and SK Hynix Inc..

RTX Corporation business model: Pratt's business model has a unique economic architecture: it often sells engines at cost or below cost when launching new platforms, accepting short-term losses in exchange for locking in decades of high-margin aftermarket service revenue. These sole-source positions represent extraordinary competitive advantages, though they also attract periodic government scrutiny about pricing. By mid-2024, additional charges had accumulated, and the program was still managing fleet removals and shop visit scheduling with airline customers who were losing revenue from grounded aircraft.

SK Hynix Inc. business model: The pricing architecture for SK Hynix's products is bifurcated between highly commoditized, spot-market pricing for legacy consumer memory, and negotiated, contract-based pricing for advanced-node enterprise and AI memory. Conversely, during a downcycle, the fixed depreciation and interest expenses rapidly consume cash reserves, forcing the company to slash capital expenditures and reduce wafer starts to stabilize pricing. The primary financial risk is the immense depreciation burden associated with its new fab construction; as the Yongin and Indiana facilities come online in 2026 and 2027, the company will incur billions of dollars in new depreciation expenses that will require sustained high memory pricing and high use rates to absorb, creating a high break-even point that could result in significant losses if another memory downcycle occurs before the fabs reach full scale. This packaging advantage is critical for AI data centers, where the thermal output of AI server racks is the primary bottleneck preventing the deployment of higher-density computing clusters; by using a liquid molding compound that fills the microscopic gaps between the stacked dies and acts as a highly efficient heat spreader, SK Hynix's MR-MUF process reduces the thermal resistance of the HBM package by over 20% compared to the traditional non-conductive film (NCF) method used by Samsung, creating a compelling economic value proposition that transcends simple per-gigabyte pricing and has secured SK Hynix the primary design win for Nvidia's H200 accelerator. The founding philosophy was simple but audacious: to design and manufacture the most advanced, highest-density memory chips in the world, competing directly with the entrenched Japanese conglomerates like Toshiba, NEC, and Hitachi who were then dominating the global memory market with superior quality and aggressive pricing, and the emerging American startups like Micron who were pioneering new process technologies.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of RTX Corporation stack up against those of SK Hynix Inc..

RTX Corporation competitive advantage: The company's operational scale is genuinely staggering. For American audiences, RTX is also a story of industrial employment at scale: 180,000 jobs in engineering, manufacturing, software development, and program management, spread across facilities in Connecticut, Texas, Florida, Indiana, Arizona, and dozens of other states. However, the structural advantages of scale, certification, security clearances, and supply chain depth continue to favor RTX in competitions for large, complex programs. RTX's competitive moat is built on several reinforcing structural advantages that are genuinely difficult for rivals to replicate on any realistic time horizon. The first and most powerful advantage is the installed base effect. The second advantage is classification and security clearance infrastructure. Third, RTX benefits from deep program lock-in on major defense platforms.

SK Hynix Inc. competitive advantage: Because HBM requires significantly more wafer area per gigabyte than standard planar DRAM, and involves complex advanced packaging processes that yield lower output per wafer, the effective supply of HBM is structurally constrained, allowing SK Hynix to negotiate multi-year, fixed-price allocation agreements with hyperscalers that guarantee gross margins exceeding 50% for the HBM segment, regardless of broader memory market fluctuations. Under CEO Kwak Noh-jeong and backed by the immense resources of the SK Group conglomerate, the business has successfully pivoted its product mix toward High Bandwidth Memory (HBM3E) and advanced-node data center solutions, securing multi-year supply agreements with Nvidia and the world's largest hyperscalers to power the next generation of artificial intelligence accelerators. The company's competitive moat is anchored by its proprietary MR-MUF advanced packaging technology, its aggressive adoption of 1-beta and 1-gamma DRAM nodes, and the immense financial barriers to entry that protect the triopoly from new competition. The competitive dynamic between SK Hynix and Samsung is defined by a bitter, decades-long rivalry for absolute scale and technological supremacy in the South Korean semiconductor ecosystem; Samsung possesses a massive revenue base and vertical integration advantage, producing its own logic chips, displays, and mobile devices, which allows it to consume a significant portion of its own memory production and absorb market downturns better than pure-play memory vendors. SK Hynix's competitive advantage lies in its ability to prove superior thermal performance in HBM packaging, higher bit density in DRAM, and a comprehensive enterprise SSD portfolio via Solidigm, a value proposition that resonates powerfully with Western hyperscalers seeking to maximize the compute density of their AI clusters. The competitive moat is also defended through the sheer scale of the capital investment required to compete; with a single leading-edge fab costing over $15 billion, and the R&D required to master MR-MUF packaging and 321-layer NAND stacking running into the billions annually, the financial barrier to entry ensures that the triopoly will remain intact for the foreseeable future, protecting SK Hynix's long-term pricing power and market share. The second pillar of the competitive advantage is SK Hynix's aggressive adoption of leading-edge DRAM nodes, specifically its 1-beta and 1-gamma technologies, which use advanced multi-patterning and selective EUV integration to achieve the highest bit density per wafer in the industry. The fifth pillar is the immense financial and strategic backing of the SK Group, South Korea's second-largest conglomerate, which provides SK Hynix with access to virtually unlimited capital, deep government backing through the K-Chips Act, and a diversified ecosystem of affiliated companies that supply everything from advanced chemicals to industrial gases, insulating the company from the supply chain vulnerabilities that plague standalone semiconductor manufacturers. SK Hynix is also pioneering the concept of 'customer-defined HBM', where hyperscalers like Google and Amazon can customize the base die and memory architecture to optimize for their proprietary AI silicon, a strategic move that deepens the switching costs and locks SK Hynix into the long-term roadmaps of the world's largest cloud providers.

Future prospects matter as much as current results. The growth strategies below explain how RTX Corporation and SK Hynix Inc. each plan to expand from here.

RTX Corporation growth strategy: But 2023 brought a complication that reminded investors that aerospace engineering has no shortcuts: a powder metal contamination issue in older Pratt & Whitney GTF engines forced the company to ground hundreds of aircraft for accelerated inspections and parts replacement. For investors, military planners, airline executives, and students of American industrial history alike, RTX is a story impossible to ignore. CEO Christopher Calio, who succeeded Gregory Hayes in 2023, leads the enterprise with a focus on organic growth, R&D investment, and shareholder returns. RIS focuses on advanced sensors, intelligence systems, surveillance, reconnaissance platforms, and cybersecurity — essentially the information technology layer of modern warfare. The company's ability to serve both commercial aviation — a fundamentally optimistic, growth-oriented industry — and national defense — an industry shaped by threat assessment and geopolitical realism — gives it a distinctive resilience that pure-play defense or pure-play aerospace companies cannot match. This segment is most exposed to competition from defense-focused technology companies and systems integrators, where contract awards are heavily influenced by personnel relationships, program incumbency, and agency-specific trust developed over years of classified performance. A startup cannot build the Patriot system's 40-year operational history. The competitive threat from technology entrants is most acute in software, AI, and autonomous systems — precisely the domains where RTX has been investing most aggressively through its RIS segment and its internal venture investments. This growth was driven by strong performance across all four segments, though the pace was uneven. The consequence was that hundreds of aircraft — predominantly Airbus A320neo and A220 jets operated by airlines worldwide — required accelerated engine inspections and, in many cases, replacement of affected components. The defense industry broadly, and RTX specifically, has faced investor scrutiny over development program cost overruns that can transform profitable contracts into loss-generating obligations. Building the organizational and physical infrastructure to compete for classified intelligence systems contracts takes decades. New entrants — even well-capitalized technology companies — cannot simply acquire this capability. It must be grown organically through sustained engagement with defense customers, demonstrated performance on progressively sensitive programs, and culture aligned with government security requirements. RTX's growth strategy rests on four interconnected pillars: aftermarket expansion, international defense sales growth, next-generation platform positioning, and portfolio optimization. As the global fleet of GTF-powered aircraft grows — Airbus has delivered thousands of A320neo family jets and has a backlog of thousands more — the aftermarket revenue opportunity expands proportionally. Each new engine entering service creates a 25-to-30-year stream of parts and service revenue. RTX has invested in expanding its MRO network, including new facilities in Singapore and Poland, to capture this demand closer to its origins. Collins Aerospace is pursuing a similar aftermarket expansion strategy, investing in connectivity and cabin upgrade programs that generate recurring revenue from existing airline customers. International defense sales growth is perhaps the highest-velocity growth vector in RTX's near-term outlook. The company has publicly identified international as a key growth driver, with the addressable market expanding as European NATO members increase procurement and Indo-Pacific allies modernize air defense architectures. RTX aims to grow international defense sales from roughly 35% of defense revenue toward 40 to 45% over the medium term. Portfolio optimization, following the 2023 spinoffs of Carrier and Otis, has left RTX as a pure-play aerospace and defense company, allowing management focus and capital allocation to be concentrated on the highest-return opportunities within the core sectors. On the commercial aviation side, the International Air Transport Association projects continued passenger traffic growth through 2030, underpinned by Asia-Pacific demand. Airlines are accelerating replacement of older aircraft with fuel-efficient narrow-bodies powered by GTF and LEAP engines, which should drive long-term Pratt & Whitney aftermarket growth once the near-term GTF remediation burden diminishes. In the postwar decades, Raytheon pursued an aggressive acquisition strategy, acquiring companies in defense electronics, missile systems, and professional services. The concurrent spinoffs of Carrier Global Corporation and Otis Worldwide Corporation — separating UTC's building products businesses — focused the new RTX squarely on aerospace and defense.

SK Hynix Inc. growth strategy: This land-and-expand strategy within the data center is critical; as AI models grow from hundreds of billions to trillions of parameters, the memory bandwidth required to prevent the GPU from idling increases exponentially, ensuring that SK Hynix's content-per-server metrics continue to scale regardless of broader macroeconomic headwinds in the consumer electronics sector. The capital allocation strategy under the SK Group umbrella has deliberately shifted away from pursuing maximum market share in low-margin consumer electronics, focusing instead on capturing the highest-value segments of the data center and AI markets. The land-and-expand strategy within the data center is driven by the exponential growth of AI model parameters; as large language models scale from hundreds of billions to trillions of parameters, the memory bandwidth required to prevent the GPU from idling increases proportionally, ensuring that SK Hynix's content-per-server metrics continue to scale even if the total number of servers shipped remains flat. The overall business model is a masterclass in extreme industrial engineering and advanced packaging: acquire the technological capability to print the smallest possible transistor and stack the highest possible number of 3D layers, expand revenue by capturing the most demanding AI and data center workloads, retain the customer through deep architectural integration and multi-year allocation agreements, and defend the margin through relentless yield optimization and government-subsidized capacity expansion. SK Hynix counters this by completely exiting the commodity, low-margin segments and focusing exclusively on the high-performance, advanced-node segments where Chinese manufacturers lack the lithography tools and advanced packaging expertise to compete, effectively ceding the bottom 20% of the market to protect the margins of the top 80%. This consolidation has fundamentally altered the competitive dynamics, replacing the destructive, market-share-at-all-costs price wars of the 1990s and 2000s with a more rational, profit-focused oligopoly where capacity discipline is prioritized over volume growth. The financial trajectory is characterized by a deliberate shift in product mix; the percentage of revenue derived from HBM and data center-centric products has grown from less than 10% in FY2022 to over 30% in FY2024, structurally elevating the company's long-term gross margin profile and reducing its exposure to the volatile consumer electronics cycle. A secondary, acute challenge is the brutal, inherent cyclicality of the global memory semiconductor market, a phenomenon driven by the massive lead times required to build fabrication capacity and the commodity-like nature of standard DRAM and NAND products. The third pillar is the deep, architectural integration with Nvidia and other AI chip designers; SK Hynix's engineering teams work directly with Nvidia's architecture groups years in advance of product launches to co-design the custom PHY interfaces, thermal spreaders, and interposer routing required for HBM integration. SK Hynix's growth strategy is explicitly defined by the 'Advanced Node and AI Content' framework, a systematic initiative to capture specific market segments by deploying targeted technologies that expand the company's share of the AI server bill of materials (BOM) without relying on unit volume growth. The strategy is executed through the aggressive ramp of HBM3E and the development of HBM4, which will increase the memory content per AI accelerator from 80GB in the H100 to over 192GB in next-generation accelerators, ensuring that SK Hynix's revenue grows in direct proportion to the performance capabilities of next-generation AI silicon. This growth strategy is executed through a land-and-expand motion that relies on deep architectural integration with Nvidia, AMD, and custom AI chip designers; rather than competing on price in the commodity market, the engineering team focuses on co-developing the custom PHY interfaces, thermal solutions, and customer-defined base dies required for next-generation HBM stacks, creating a level of technical lock-in that guarantees multi-year supply agreements and premium pricing. The channel partner strategy is also evolving to support this framework; SK Hynix is training its network of global module makers and distribution partners to sell the advanced-node server DRAM and Solidigm enterprise SSDs as comprehensive 'AI Infrastructure' packages, offering customers validated compatibility lists and performance benchmarks that justify the premium pricing of SK Hynix's leading-edge products. The company is also pursuing strategic, tuck-in acquisitions to fill gaps in its advanced packaging and controller capabilities; recent investments in packaging startups and controller design firms are specifically targeted to enhance the HBM production yield and the performance of data center SSDs, providing customers with higher-reliability products without requiring the development of new foundational silicon technologies from scratch. The international growth strategy involves establishing a balanced, geographically diversified manufacturing footprint, using the South Korean K-Chips Act to build leading-edge DRAM capacity in the Yongin cluster, while simultaneously expanding its advanced NAND and HBM packaging facilities in the United States and Asia to maintain proximity to the global supply chain ecosystem and customer base, mitigating the geopolitical risks associated with its Chinese operations. The growth strategy also includes the development of industry-specific memory solutions for automotive, industrial, and edge AI applications, which incorporate specialized software features and ruggedized hardware designs tailored to the specific operational requirements and longevity demands of each vertical, expanding the TAM beyond the traditional data center and mobile markets. The financial target of this growth strategy is to increase the average selling price (ASP) per gigabyte across the entire product portfolio by 20% annually, a figure that will be driven entirely by the advanced-node product mix shift and the successful penetration of the AI server market, without requiring a proportional increase in the sales and marketing headcount. The transition to EUV lithography for 1-gamma and 1-delta DRAM is also a critical component of the growth strategy, allowing SK Hynix to achieve the necessary bit density reductions to maintain its cost leadership and gross margin expansion in the face of intense competitive pressure from Samsung and Micron. The company is aggressively expanding its total addressable market (TAM) by capitalizing on the exponential growth of AI training and inference workloads, which require exponentially more memory bandwidth and capacity than traditional cloud computing tasks. The introduction of HBM4, scheduled for volume production in 2026, is the cornerstone of this strategy; HBM4 will use a custom base die designed in partnership with logic foundries to integrate advanced compute capabilities directly into the memory stack, delivering unprecedented bandwidth and reducing the latency between the GPU and the memory, a critical requirement for training trillion-parameter models. The company's long-term financial model targets $80 billion in annual revenue by fiscal year 2028, a goal that requires maintaining a 15% compound annual growth rate (CAGR) while expanding gross margins to the mid-40% range through the operating leverage of the advanced-node product mix and the full absorption of the K-Chips Act and US CHIPS Act subsidies. However, the structural shift toward AI-driven computing is irreversible, and SK Hynix's technological leadership in HBM packaging and advanced-node DRAM positions it to capture the majority of the memory content growth in the AI server market over the next decade. Chung Ju-yung, recognizing that memory semiconductors were the 'rice' of the digital age, established Hyundai Electronics as a dedicated semiconductor division, tasking a small team of engineers with the seemingly impossible mission of building a world-class DRAM fabrication facility from scratch in Icheon, a rural area southeast of Seoul. The team operated out of a modest facility in Icheon, focusing entirely on building the core architecture of the company's first product: a 64K SRAM and a 256K DRAM chip that would use the most advanced n-channel MOS technology available. To bridge the technological gap, Hyundai Electronics engaged in a controversial and aggressive strategy of reverse-engineering and acquiring foreign technology, including a pivotal and highly disputed licensing agreement with Micron Technology for 64K DRAM design rights, a move that would later trigger a massive intellectual property lawsuit in the 1990s when the US ITC ruled that Hyundai had infringed on Micron's patents. The initial customer base consisted of domestic electronics manufacturers like Samsung and GoldStar (now LG), who were eager to secure a local supply of memory chips to feed their rapidly expanding consumer electronics export businesses, as well as a handful of forward-thinking US computer manufacturers who were looking to diversify their supply chains away from Japan.

A closer look at the financial trajectory of RTX Corporation and SK Hynix Inc. rounds out the comparison.

RTX Corporation: RTX reported $88.603 billion in FY2025 sales, up from $80.738 billion in FY2024 and $68.920 billion in FY2023. Net income rose to $6.732 billion in FY2025 from $4.774 billion in FY2024. Q1 2026 sales were $22.076 billion and net income was $2.059 billion, keeping the company on pace with strong commercial aerospace aftermarket demand and elevated defense demand.

SK Hynix Inc.: SK hynix reported FY2025 revenue of KRW 97.1467T, operating profit of KRW 47.2063T, and net profit of KRW 42.9479T. On a USD-normalized basis for this dataset, that is roughly $67.0B of revenue and about $30.1B of net profit. The result marks a step-change from the 2023 memory downturn and reflects the pricing power of HBM, server DRAM, enterprise SSDs, and AI data-center demand. The latest operating update before July 22, 2026 was Q1 2026. SK hynix reported revenue of KRW 52.5763T, operating profit of KRW 37.6103T, and net profit of KRW 40.3459T. The company had scheduled its Q2 2026 earnings release for July 29, 2026, so Q1 remained the latest reported quarter at this review date. The strategic question is how durable this AI memory cycle is. SK hynix has a strong HBM position, but memory remains cyclical, capital-intensive, and exposed to pricing, customer concentration, and capacity timing.
