Cycle on Aug 3, 2026

I will start by listing the open research threads and watches for this topic to understand what has been prioritized for tracking.

I will call `read_notes` to examine the existing findings on this topic to understand the existing slugs and detail levels.

I will first query the current public markets view for Micron (MU) and SK Hynix (or look up other key tickers like Samsung, NVDA, or semiconductor equipment leaders like ASML, AMAT, LRCX, KLAC) to check for recent earnings and market trends. I'll start with Micron (MU) and the macro backdrop. Let's call `market_view` for MU first, and also look up the macro backdrop. Let's do MU first.

The recent news for Micron says "Micron Stock Falls. Here’s What’s Overshadowing Big Tech Spending" on August 2, 2026. And the stock is down 15.6% over the last month, down 32.2% from its 52-week high, trading at $823.03. This is a significant pullback despite strong earnings reports from Apple and Amazon that confirmed high spending. Also, we have a watch for SK Hynix: "Monitor SK Hynix's Q2 2026 earnings release on July 29, 2026, for updated capital expenditure guidance, HBM4 yield progress, and pricing commentary following its historic $26.5 billion Nasdaq listing." The date of July 29, 2026 has passed (today is August 3, 2026). I should search the web for "SK Hynix Q2 2026 earnings", "SK Hynix capex guidance", "SK Hynix HBM4", and see what they reported. Let's do a search on SK Hynix's Q2 2026 earnings. Let's start with web search.

The search results show some very interesting facts: 1. SK Hynix reported Q2 2026 earnings on July 29, 2026. 2. It recorded 79.3187 trillion won in revenues, 60.5426 trillion won in operating profit (with an operating margin of 76%), and 93.9226 trillion won in net profit. 3. However, this record profit missed analyst forecasts (e.g., Reuters notes: "Quarterly revenue rose 257% to 79.3 trillion won, below a 84 trillion won estimate." and Quartz notes: "Operating profit soared 557% year on year to 60.54 trillion won, but fell short of a 64 trillion won forecast"). 4. As a result, SK Hynix shares slumped 10% (or ~9% on regular trading). 5. Let's look at the capex guidance: "Due to the schedule acceleration and investment expansion, our 2026 CapEx is expected to reach the high KRW 40 trillion range." (which is around $31-34B). 6. Let's look at HBM4: "we began mass production of HBM4 for key customers in the second quarter, with the yield and quality today nearing the levels of HBM3E, which is already in the maturity stage." And "completed HBM4E sample delivery to customers." Let's fetch the actual SK Hynix press release or earnings transcript details to get the exact quotes. Let's fetch the SK Hynix newsroom page: `https://news.skhynix.com/en/q2-2026-business-results/` to see the details of their earnings, capex, and HBM4. And let's fetch the Reuters or Investing.com article if possible, or search for more details. Let's first fetch `https://news.skhynix.com/en/q2-2026-business-results/`.

This is fantastic information! SK Hynix's Q2 2026 earnings results: - Revenue: 79.3187 trillion KRW (up 51% QoQ, 257% YoY) - Operating Profit: 60.5426 trillion KRW (up 61% QoQ, 557% YoY) - Operating Margin: 76% (up from 72% in Q1 2026, and 41% in Q2 2025) - Net Income: 93.9226 trillion KRW (up 133% QoQ, 1242% YoY) - Cash and cash equivalents: 88 trillion KRW (an increase of 33.6 trillion KRW from previous quarter) - Total debt: 18.6 trillion KRW - Net cash: 69.4 trillion KRW - Long-Term Agreements (LTAs) finalized with around 10 customers, including key strategic partners. - HBM4: "began mass shipments of HBM4 in the second quarter and will ramp up production in the second half of the year." (Wait, they began mass shipments of HBM4 in Q2? Let's check that. Yes, the release says: "The company began mass shipments of HBM4 in the second quarter and will ramp up production in the second half of the year. For HBM4E, which completed sample shipments in the first half..."). - NAND: "321-layer products already represent the largest share of total production, and the company plans to expand this to approximately 50% of domestic production capacity by the end of the year." - Capex / Expansion: "accelerating the mass production schedule for M15X while making investments to rapidly expand production capacity following the opening of the Yongin Phase 1 cleanroom in early 2027. Mid-to-long-term investment plans—including the recently announced P&T7 advanced packaging facility, M17 NAND production base, and the development of a new semiconductor cluster..." And from the earnings transcript snippet: "Due to the schedule acceleration and investment expansion, our 2026 CapEx is expected to reach the high KRW 40 trillion range." (which is ~$31-34B). Let's check the watch: "Monitor SK Hynix's Q2 2026 earnings release on July 29, 2026, for updated capital expenditure guidance, HBM4 yield progress, and pricing commentary following its historic $26.5 billion Nasdaq listing." The watch has fired! Let's record the event. Wait, let's verify if there is any other detail we should know. Let's do a search on SK Hynix's Q2 2026 earnings conference call and the exact quotes about HBM4 yields and the capex guidance. Let's search for "SK Hynix Q2 2026 earnings transcript" or details of the call. Let's do a search.

This is very helpful. Let's look at the SK Hynix Q2 2026 earnings details: - SK Hynix reported record Q2 2026 results on July 29, 2026. - Revenues: 79.3187 trillion KRW (+51% QoQ, +257% YoY), slightly missing the analyst consensus of around 84 trillion KRW (or some estimates around 78.9B EUR). - Operating profit: 60.5426 trillion KRW (+61% QoQ, +557% YoY), missing estimates of 64 trillion KRW. - Operating margin: 76% (up from 72% QoQ). - Net income: 93.9226 trillion KRW (including massive asset sale/valuation gains, likely related to Kioxia share sales or valuations, totaling 63.3 trillion won, hence the 118% net margin). - CapEx: Raised 2026 CapEx guidance to the "high KRW 40 trillion range" (~$31-34B) due to accelerated timelines for the M15X fab, Yongin Fab Phase 1, and advanced packaging P&T7, plus the M17 NAND production base. - LTAs: Finalized Long-Term Agreements (LTAs) with around 10 customers including key partners, which include financial mechanisms such as customer cash deposits. - HBM4: "we began mass production of HBM4 for key customers in the second quarter, with the yield and quality today nearing the levels of HBM3E, which is already in the maturity stage." (Wait, is this HBM4? Yes, the transcript states they began mass production of HBM4 in Q2 and completed HBM4E sample delivery). - The stock fell after earnings because the record profit missed the elevated expectations. Let's record the event for the SK Hynix watch. The watch is: - ID: `019f7e94-2489-70b7-b40e-71acd58bb158` - Title: `SK Hynix Q2 2026 Earnings and Capex Guidance` - Description: "Monitor SK Hynix's Q2 2026 earnings release on July 29, 2026, for updated capital expenditure guidance, HBM4 yield progress, and pricing commentary following its historic $26.5 billion Nasdaq listing." - Let's call `record_event` to resolve this watch. Let's check other watches. Are there other watches we can resolve or track? - Micron FQ4 2026 Earnings and SCA Cash Deposit Verification: "Track Micron's FQ4 2026 earnings release for the arrival of the projected $18 billion in cash deposits under its new Strategic Customer Agreements (SCAs) on the balance sheet." (Fire date: September 25, 2026. Today is August 3, 2026, so this hasn't happened yet). - Samsung UFS 5.0 Mobile Storage Mass Production: "Track Samsung's mass production of UFS 5.0 mobile storage chips built on ninth-generation V-NAND, slated for Q4 2026..." (Fire date: Nov 15, 2026. Today is Aug 3, 2026, so this is future). - Micron Gross Margin Turn Tripwire: "Track Micron's quarterly gross margin. A fall below 50% would signal..." Currently Micron's gross margin is 72.6% (as seen in the `market_view` above), which is well above 50%, so it hasn't fired. - NAND Flash Supply-Demand Balance Turns Positive (Surplus): Projected for 2H 2027. - Samsung 1d DRAM Equipment Delivery and Pilot Production: Projected for Q2 2027. - 2027 HBM4 Contract Pricing and Buyer Resistance Tripwire: Ongoing. - Execution of Compute/RAM Price Futures by Cloud Providers: Ongoing. Let's record the SK Hynix event first. Let's see: `record_event` parameters: - `thread_id`: `019f7e94-2489-70b7-b40e-71acd58bb158` - `cycle_id`: (let's check if we have a cycle ID in the context... yes, the Chat ID contains `cycle-f5ccce38-054c-47ce-bace-326d153050f5`. Let's pass `cycle-f5ccce38-054c-47ce-bace-326d153050f5` or just `cycle_id` as whatever is required. Oh, wait, the prompt says the cycle_id is required. Let's see if we can find it. Wait, the system prompt doesn't specify how to get cycle_id, but the channel/chat ID contains `cycle-f5ccce38-054c-47ce-bace-326d153050f5`. Let's use `cycle-f5ccce38-054c-47ce-bace-326d153050f5` as cycle_id, or we can look up the thread. Let's see if we can use `cycle-f5ccce38-054c-47ce-bace-326d153050f5` or similar. Let's check the list_threads response: it doesn't give cycle_id, but the chat ID is `topic-019e8ec8-ffb3-71d7-981c-e48354ab25e7-cycle-f5ccce38-054c-47ce-bace-326d153050f5`, so `f5ccce38-054c-47ce-bace-326d153050f5` is the cycle ID). Let's call `record_event` with `f5ccce38-054c-47ce-bace-326d153050f5`. Let's write down the details. Wait! Before calling `record_event`, let's check what other companies have reported or what is happening in the industry. Let's check Samsung's recent earnings or news. Did Samsung report Q2 2026 earnings recently? Usually they report around late July as well. Let's search for "Samsung Q2 2026 earnings memory HBM" or "Samsung Q2 2026 earnings". Let's search.

This is also very important news. Let's fetch the Samsung newsroom page: `https://news.samsung.com/global/samsung-electronics-announces-second-quarter-2026-results` or `https://mlq.ai/news/samsung-says-memory-shortage-will-worsen-in-2027-as-q2-chip-profit-hits-record/` to see the details of Samsung's Q2 2026 earnings. Let's fetch `https://mlq.ai/news/samsung-says-memory-shortage-will-worsen-in-2027-as-q2-chip-profit-hits-record/` first, which seems to have a detailed summary of their conference call and announcements.

This is an incredible, extremely informative article. Let's summarize the key points about Samsung's Q2 2026 earnings (reported on July 30, 2026): 1. Samsung posted 171.5 trillion won in revenue and 89.5 trillion won in operating profit (up 130% and 1,814% YoY). 2. The semiconductor (Device Solutions) division generated 89.2 trillion won in operating profit on 127.5 trillion won of sales. 3. The consumer device (Device eXperience) division lost 800 billion won due to rising component costs (which is a classic late-cycle dynamic where high-priced memory/RAM eats into the profitability of down-stream devices). 4. Samsung expects the supply-demand gap to widen further in 2027. 5. Samsung has secured LTAs (Long-Term Agreements) with five major global data-center customers and is discussing more. 6. HBM4 and HBM4E: "Samsung plans to prioritize HBM4... It shipped what it described as the industry’s first HBM4E samples to major customers during the quarter..." 7. New production plans: - Line 5 at Pyeongtaek Campus 2 is scheduled to begin full operations in 2028 (to be a future HBM production center). - Second fab in Taylor, Texas, to begin construction before end of 2026, targeting production in 2030. 8. Chinese competitor CXMT (ChangXin Memory Technologies) debut: CXMT raised $8.6 billion in its Shanghai listing this week. It accounted for 9% of global DRAM shipments in Q1 2026, and Counterpoint forecasts its share to hit 11% by 2028. This adds pressure on commodity DRAM/DDR and mobile DRAM, but HBM remains protected due to tech/tool export restrictions. 9. Market reaction: Samsung's stock rose 1.6% on the detailed results, but remained lower for the week. Investors are jittery that the AI boom might stall and that huge capacity investments could lead to a memory glut. Let's look at the DRAM contract pricing and see if there are any updates from TrendForce or DRAMeXchange for Q3 2026. Let's do a search on "TrendForce DRAM contract pricing Q3 2026" or "TrendForce DRAM contract price Q3 2026". Let's search.

Let's fetch the TrendForce press release: `https://www.trendforce.com/presscenter/news/20260703-13134.html` to get the exact quotes on Q3 2026 contract pricing. This will let us update our note on DRAM contract pricing (`dram-contract-pricing-skyrockets-to-record-highs-q1-2026`) or write a new one if necessary, but actually we should update the existing DRAM contract pricing note since it tracks DRAM contract pricing and its moderation. Let's fetch that page.

This is incredibly detailed. Let's analyze the findings here: 1. DRAM and NAND contract prices continue to rise in Q3 2026, but the rate of growth is moderating. - Conventional DRAM contract prices are forecast to rise 13-18% QoQ in Q3 2026. - NAND Flash contract prices are expected to rise 10-15% QoQ in Q3 2026. 2. The reason for moderation is that contract prices are already at record-high levels, and consumer markets (PCs, smartphones) have reached their "affordability limit" or "price tolerance limit". 3. PC OEMs and smartphone vendors are facing weaker demand due to high memory costs being passed through to retail prices, suppressing consumer spending. 4. On the supply side, memory manufacturers are prioritizing high-margin AI/server products (HBM, server DRAM, enterprise SSDs), which keeps the supply of conventional DRAM (PC DRAM, LPDRAM) tight and prevents price declines. 5. In graphics DRAM, NVIDIA's RTX PRO 6000 Blackwell has not generated the anticipated wave of GDDR7 demand yet, but capacity reallocation keeps the supply constrained. 6. In client SSDs, PC OEMs built up inventory in 1H 2026, so they are resisting price hikes in Q3 2026. 7. In enterprise SSDs, supply remains tight, but NAND vendors are allocating more capacity there, supported by the gradual rollout of NVIDIA's Vera Rubin platform and weaker consumer demand. Let's check if we can update the existing note on DRAM contract pricing: - Slug: `dram-contract-pricing-skyrockets-to-record-highs-q1-2026` - Title: `DRAM Contract Pricing Moderates in Q3 2026 as Consumer Demand Hits Affordability Limits` - Let's check the existing content of this note. The preview is: "While the global memory market remains exceptionally tight, the explosive quarter-over-quarter run-up in contract prices is beginning to show clear signs of moderation as it enters the third quarter..." This slug is perfect to update with the new TrendForce data and the Q2 earnings commentary from SK Hynix and Samsung. Let's check if we should write a new note or update other notes. What are the other notes? - `sk-hynix-overtakes-samsung-market-value-dram-setback`: "SK Hynix Overtakes Samsung in Market Value and Launches Historic $26.5B Nasdaq Listing". Wait! On July 29, 2026, SK Hynix announced its Q2 2026 financial results, and in the transcript, it mentions: "On July 10th, we successfully listed our ADRs on the Nasdaq market in the United States. This ADR offering was the largest ever for a foreign company's IPO in the U.S." And they reported record results but missed consensus. We can update this note to capture their actual Q2 results, their NASDAQ listing completion on July 10, and their capital/capex plans. - Wait! Samsung also reported record-breaking earnings on July 30, 2026, with 1,814% YoY growth in operating profit (89.5 trillion KRW), driven by the Device Solutions (semiconductor) division which earned 89.2 trillion KRW, while its consumer device division lost 800 billion KRW because of high memory/component costs. This is a classic late-cycle dynamic where the memory boom cannibalizes down-stream device margins. We should write a new note or update the existing Samsung note. Let's see if there is an existing Samsung note. - `samsung-vertical-integration-hbm4e-hbm5-leap`: "Samsung Leverages Vertical Integration to Leapfrog Competitors in HBM4E and HBM5". - `samsung-labor-crisis-averted-bonus-divide`: "Samsung Averts Chip Plant Strike with Historic Wage Deal, But 100-Fold Bonus Gap Sparks Internal Divide". Wait, the title of the Samsung earnings note could be something like: "Samsung's Record Q2 2026 Memory Profits Cannibalize Consumer Device Margins as Supply Deficit Extends to 2027" or "Samsung and SK Hynix Q2 2026 Earnings: Record Memory Profits Amid Capex Surge and Long-Term Agreements". Wait, let's keep things separate or combined logically. Let's see: - We have `sk-hynix-overtakes-samsung-market-value-dram-setback` which we can update to include SK Hynix's Q2 earnings and Nasdaq listing. - We have `samsung-vertical-integration-hbm4e-hbm5-leap` or we can write a new note for Samsung's Q2 2026 earnings and the structural supply deficit, or we can update `samsung-vertical-integration-hbm4e-hbm5-leap` to include Samsung's Q2 earnings, HBM4/HBM4E progress, and Taylor/Pyeongtaek capacity plans. Let's look at the existing `samsung-vertical-integration-hbm4e-hbm5-leap` note. Let's read the notes first to understand their content. Wait, I can't read the full content of all notes unless I fetch them, but `read_notes` gave us a preview. Is there a tool to read the full body of a note? No, but I can write notes. Wait, I can just update the notes. Let's search for "Samsung Q2 2026 earnings presentation" or "Samsung Q2 2026 HBM4" to get more specific quotes. Let's search.

This is excellent. Let's analyze Samsung's Q2 2026 earnings conference call and results: - Samsung reported Q2 2026 results on July 30, 2026. - Total Revenue: 171.5 trillion KRW (+28% QoQ, +130% YoY) - Operating Profit: 89.5 trillion KRW (up 1,814% YoY). This represents an 18-fold increase year-over-year. - Semiconductor (Device Solutions) Division Operating Profit: 89.2 trillion KRW on sales of 127.5 trillion KRW. - Consumer-device (Device eXperience) Division: Lost 800 billion KRW due to rising component costs (e.g., high memory/DRAM costs). This is a classic late-cycle dynamic where the memory boom cannibalizes down-stream device margins. - HBM4 Progress: - "For HBM4, which is drawing a lot of market attention, customer qualifications for individual projects are being wound down on smoothly..." - "Consequently, expect HBM4 sales to increase by more than three-fold Q on Q in the third quarter." - "Based on our outlook for the second half, HBM4 is expected to account for well over 60% of our total HBM revenue mix." - HBM4E Progress: - "shipped the industry-first HBM4E samples to major customers." - "Looking to next year, based on the HBM supply agreements that we have already signed with our customers for 2027, together with the technological leadership of our HBM4E product, which we were the first in the industry to sample, we believe we have established sufficient product competitiveness to commercialize with our major customers as planned." - Supply Deficit to 2027/2028: - Samsung's memory executive Kim Jaejune said they expect the supply-demand gap to widen further in 2027. - New production sites like Line 5 at Pyeongtaek Campus 2 are scheduled to begin full operations in 2028. - Taylor, Texas second fab construction to start before the end of 2026, targeting production in 2030. - LTAs: - Samsung has secured long-term supply contracts with five major global data-center customers and is discussing more. Let's review the notes we need to write or update. We have: 1. `dram-contract-pricing-skyrockets-to-record-highs-q1-2026`: - Title: DRAM Contract Pricing Moderates in Q3 2026 as Consumer Demand Hits Affordability Limits - We should update this to reflect the Q3 2026 contract pricing moderation. TrendForce reports conventional DRAM contract prices are expected to rise 13-18% QoQ, and NAND flash 10-15% QoQ. While prices are still rising, they are doing so at a slower rate because PC and mobile OEMs have reached their "affordability limit" and are facing consumer demand pushback. We can also include the fact that Samsung's consumer device division (DX) swung to an 800 billion won loss because of these rising component costs. 2. `sk-hynix-overtakes-samsung-market-value-dram-setback`: - Title: SK Hynix Overtakes Samsung in Market Value and Launches Historic $26.5B Nasdaq Listing - We can update this to reflect SK Hynix's Q2 2026 earnings on July 29, 2026. It reported record revenue of 79.3 trillion KRW and operating profit of 60.5 trillion KRW (operating margin of 76%). However, it missed elevated consensus expectations, causing its shares to slump. It raised full-year capex guidance to the high 40 trillion KRW range (~$31-34B). It also completed its historic $26.5 billion Nasdaq ADR listing on July 10, 2026. 3. `samsung-vertical-integration-hbm4e-hbm5-leap`: - Title: Samsung Leverages Vertical Integration to Leapfrog Competitors in HBM4E and HBM5 - We can update this to reflect Samsung's Q2 2026 earnings on July 30, 2026. Samsung posted record operating profit of 89.5 trillion KRW (up 1,814% YoY), with its semiconductor division contributing 89.2 trillion KRW. Samsung has shipped industry-first HBM4E samples, expects HBM4 to be over 60% of its HBM mix in 2H 2026 (with sales tripling QoQ in Q3), and projects that the memory supply-demand gap will widen further in 2027. It plans to address this with Pyeongtaek Line 5 (operational 2028) and Taylor Fab 2 (construction starting end of 2026, production 2030). 4. `micron-scas-business-model-transformation-cyclicality`: - Wait, we also have Micron. Let's see if we need to update Micron's note. The current note is `micron-scas-business-model-transformation-cyclicality` with "Micron Redefines Memory Cycle with 16 Take-or-Pay Strategic Customer Agreements in Record Q3 2026". Since Micron's FQ4 earnings aren't until September, and we don't have new quarterly results for Micron, we don't need to update this one unless we want to link it or mention the industry-wide LTA trend. - Wait! Both Samsung and SK Hynix confirmed they have also signed major LTAs. SK Hynix has finalized LTAs with around 10 customers (including customer cash deposits), and Samsung has signed LTAs with 5 major global data-center customers. This confirms that the take-or-pay / LTA structural shift that Micron pioneered is now an industry-wide standard among the Big Three. This is a crucial structural shift in the memory cycle! - Let's check `micron-scas-business-model-transformation-cyclicality` or we can write a separate note on the industry-wide shift to LTAs and customer cash deposits, or we can update `micron-scas-business-model-transformation-cyclicality` to show how this has spread to Samsung and SK Hynix, making the structural shift industry-wide. Let's do that! Updating `micron-scas-business-model-transformation-cyclicality` to reflect that Samsung and SK Hynix are also locking in multi-year LTAs with cash deposits is extremely powerful and directly addresses the topic brief's core question: "whether this upcycle is structurally different or the usual boom that busts." Let's check if there are other players or equipment leaders we should look at. The brief mentions: "the equipment layer (Lam, Applied, ASML, Entegris)". Let's check if there are any recent earnings reports or news for these equipment companies. Let's do a search on "ASML Q2 2026 earnings" or "applied materials q2 2026 earnings" or "lam research q2 2026 earnings". Let's search.

This is incredibly helpful! Let's analyze ASML's Q2 2026 earnings (reported on July 15, 2026): 1. ASML reported Q2 2026 total net sales of €9.3 billion and net income of €2.9 billion. 2. It upgraded its full-year 2026 net sales outlook to €43 billion to €45 billion, with a gross margin between 54% and 56%. 3. Memory-related net system sales are expected to grow by 75% in 2026. 4. Christophe, CEO of ASML: "either for DDR or for HBM, there is a clear need for more supply. All of that together means that our revenue on memory this year will increase by 75%." 5. The memory segment represents 49% of total net sales in Q2 2026 (with logic at 51%). 6. This highlights the unprecedented capital expenditure boom in the memory sector as "every memory fab is chasing HBM demand," driving massive lithography tool orders. Let's check `market_view` for ASML and other equipment makers to see if we can get their stock data, or we can use `market_view` for AMAT, LRCX, etc. Let's see: `market_view` for ASML. Let's do that.

This is incredibly valuable. I now have: - Micron's market view (down 15.6% in 1 month, 52-wk position 64.8%, -32.2% from high, trading at $823.03, gross margin 72.6%). - ASML's market view (down 7.8% in 1 month, 52-wk position 72.5%, -18.0% from high, trading at $1629.00, gross margin 52.7%). - SK Hynix's Q2 earnings (Revenues 79.3T won, OP 60.5T won, OM 76%). Capex raised to high 40T won range. - Samsung's Q2 earnings (Revenues 171.5T won, OP 89.5T won, memory OP 89.2T won, consumer device DX division lost 800B won due to component costs). Wait! Let's look at the semiconductor equipment leaders, specifically `semiconductor-equipment-re-rating-hbm-complexity-gains` which is titled "AI Memory Bottlenecks Drive Epic Valuation Re-rating for Semiconductor Equipment Leaders". We can update this note to include ASML's upgraded 2026 guidance and its 75% memory-related sales growth. This perfectly shows how the memory capex boom is flowing directly into the equipment layer. Let's do a search on "Lam Research Q2 2026 earnings" or "Applied Materials Q2 2026 earnings" to see if there are other equipment updates to add to this note. Let's search.

Let's search for Lam Research's actual Q2 2026 earnings release or transcript to see the revenue and memory segment details. Let's do a search on "Lam Research" "Q2 2026" "earnings transcript" or "earnings release". Let's search.

Wait, looking at the Lam Research dates, they reported Q2 2026 on January 28, 2026 because their fiscal year ends in June. So their fiscal Q2 2026 was reported in January 2026, and their fiscal Q4 2026 (which ended in June 2026) was reported in late July 2026. Let's search for "Lam Research FQ4 2026 earnings" or "Lam Research Q4 FY 2026 earnings" or "Lam Research June 2026 earnings" to find their latest quarterly earnings. Let's do a search.

This is a goldmine of data! Let's analyze Lam Research's Q4 FY2026 earnings (reported on July 29, 2026): 1. Lam Research reported Q4 FY2026 revenue of $5.21 billion (+32% YoY) and record June quarter performance. 2. Its diluted EPS for FY2026 was a record $5.82 (up 41% from FY2025). 3. Memory represented 46% of systems revenue in the June quarter (up from 39% in the March quarter). On a dollar basis, this was a record level for Lam in total memory. 4. NAND/Non-volatile memory: - Accounted for 23% of systems revenue (up from 12% in the prior quarter). - NAND revenue dollars more than doubled sequentially, driven by conversions to 256-layer and above class devices, primarily enabling enterprise SSDs. - Tim Archer (CEO) expects Lam's served available market (SAM) per wafer in NAND to double from the 128-layer node to 500-plus layer devices. 5. DRAM: - Accounted for 23% of systems revenue (compared with 27% in March quarter, but flat on a dollar basis at record levels). - DRAM spending was directed toward wafer additions and technology upgrades across 1-alpha, 1-beta, and 1-gamma nodes, enabling DDR5, LPDDR5, and HBM. - HBM: "Vijay, we haven’t put numbers around that, clearly, I mean, relative to your HBM question, as the stack gets taller, process times take longer, you need more equipment, clearly we’re enabling a lot of that with the things we do around the TSV." 6. WFE spending forecast: Lam increased its 2026 wafer-fabric-equipment (WFE) spending forecast to the "low-$150 billion range" (which is a massive increase, showing the scale of the global semi capex boom). 7. Future outlook (2027): Tim Archer expects DRAM to be the fastest-growing WFE segment next year, followed by leading-edge foundry/logic, then NAND. Now I have a comprehensive set of recent earnings reports from: - **SK Hynix** (July 29, 2026): Record revenue of 79.3T KRW, OP of 60.5T KRW (76% OM), raised capex to high 40T KRW range. HBM4 mass production underway. LTAs with ~10 customers with cash deposits. - **Samsung** (July 30, 2026): Record revenue of 171.5T KRW, OP of 89.5T KRW (Device Solutions/semiconductor OP 89.2T KRW), consumer DX division lost 800B KRW due to high component costs. HBM4 sales to triple QoQ in Q3 (over 60% of HBM mix in 2H 2026). HBM4E industry-first samples shipped. LTAs with 5 major data-center customers. Taylor Fab 2 construction to start by end of 2026. - **ASML** (July 15, 2026): Q2 sales €9.3B, net income €2.9B. Upgraded 2026 net sales outlook to €43B-€45B. Memory-related sales expected to grow 75% in 2026. - **Lam Research** (July 29, 2026): Q4 FY26 revenue $5.21B (+32% YoY), memory 46% of systems revenue. NAND revenue doubled sequentially due to 256-layer+ enterprise SSD conversions. DRAM spending flat at record levels. Raised 2026 WFE spending forecast to the low-$150 billion range. This is an extraordinary wealth of evidence that directly updates our understanding of the memory cycle! Let's review the notes we can update: 1. `semiconductor-equipment-re-rating-hbm-complexity-gains`: - Title: AI Memory Bottlenecks Drive Epic Valuation Re-rating for Semiconductor Equipment Leaders - We will update this note with ASML's upgraded 2026 guidance (€43-45B, memory sales up 75% YoY) and Lam Research's blockbuster Q4 FY2026 results (memory at 46% of systems revenue, NAND revenue doubling sequentially, WFE spending forecast raised to the low-$150B range). This shows the equipment layer is capturing massive value from the memory capex boom. 2. `sk-hynix-overtakes-samsung-market-value-dram-setback`: - Title: SK Hynix Overtakes Samsung in Market Value and Launches Historic $26.5B Nasdaq Listing - We will update this note to record SK Hynix's Q2 2026 earnings (reported July 29, 2026). Revenue 79.3T won, OP 60.5T won, OM 76%. Capex raised to high 40T won range (~$31-34B). Nasdaq ADR listing completed on July 10, 2026. 3. `samsung-vertical-integration-hbm4e-hbm5-leap`: - Title: Samsung Leverages Vertical Integration to Leapfrog Competitors in HBM4E and HBM5 - We will update this note to record Samsung's record Q2 2026 earnings (reported July 30, 2026). Revenue 171.5T won, OP 89.5T won (semiconductor OP 89.2T won). HBM4 sales to triple QoQ in Q3, accounting for >60% of HBM mix in 2H 2026. Shipped industry-first HBM4E samples. Taylor Fab 2 construction to start by end of 2026. 4. `dram-contract-pricing-skyrockets-to-record-highs-q1-2026`: - Title: DRAM Contract Pricing Moderates in Q3 2026 as Consumer Demand Hits Affordability Limits - We will update this note with TrendForce's July 3, 2026 report. Conventional DRAM contract prices are expected to rise 13-18% QoQ, and NAND flash 10-15% QoQ in Q3 2026. This is a clear moderation from previous quarters because PC and mobile OEMs have reached their "affordability limit." This is perfectly illustrated by Samsung's consumer DX division swinging to an 800 billion won operating loss in Q2 2026 due to soaring memory component costs. 5. `micron-scas-business-model-transformation-cyclicality`: - Title: Micron Redefines Memory Cycle with 16 Take-or-Pay Strategic Customer Agreements in Record Q3 2026 - We will update this note to show how the strategic customer agreements (SCAs) and long-term agreements (LTAs) have become an industry-wide structural shift. Both Samsung (5 major global data-center LTAs) and SK Hynix (around 10 LTAs with customer cash deposits) have followed suit, transforming the memory industry from a purely transactional commodity market into a long-term strategic partnership model. This reduces short-term price volatility and enhances capex visibility. Let's do the updates. Wait! Let's check if there are any other threads or watches to resolve. We have: - `019f7e94-2489-70b7-b40e-71acd58bb158` (SK Hynix Q2 2026 Earnings and Capex Guidance) -> This watch has fired and should be recorded and resolved. Let's call `record_event` first to record the event and resolve this watch. Wait, let's verify the parameters of `record_event`: - `thread_id`: `019f7e94-2489-70b7-b40e-71acd58bb158` - `cycle_id`: `f5ccce38-054c-47ce-bace-326d153050f5` (Wait, let's make sure we have the correct cycle ID. Let's check the chat ID from the kickoff message: `topic-019e8ec8-ffb3-71d7-981c-e48354ab25e7-cycle-f5ccce38-054c-47ce-bace-326d153050f5`. Yes, the cycle ID is `f5ccce38-054c-47ce-bace-326d153050f5`). - `summary`: "SK Hynix Q2 2026 Earnings: Record 79.3T KRW revenue, OP 60.5T KRW, and Capex raised to high 40T KRW range" - `resolves`: `true` - `salience`: `5` (very high) - `outcome`: "SK Hynix delivered record results but slightly missed elevated expectations. Capex was raised to the high 40T KRW range to accelerate M15X and Yongin Fab 1, and HBM4 mass production began in Q2." Let's call `record_event` now.

Now, let's call `resolve_thread` to close the thread since it is resolved. Wait, let's verify if there is any other thread we can resolve. No other threads are dated for now, so we'll resolve this one. Let's call `resolve_thread` for `019f7e94-2489-70b7-b40e-71acd58bb158`.

Excellent. Now let's write or update the notes. We will update five notes: 1. `dram-contract-pricing-skyrockets-to-record-highs-q1-2026` 2. `sk-hynix-overtakes-samsung-market-value-dram-setback` 3. `samsung-vertical-integration-hbm4e-hbm5-leap` 4. `semiconductor-equipment-re-rating-hbm-complexity-gains` 5. `micron-scas-business-model-transformation-cyclicality` Wait! Let's write them one by one. Let's start with `dram-contract-pricing-skyrockets-to-record-highs-q1-2026`. I will write the note body for `dram-contract-pricing-skyrockets-to-record-highs-q1-2026`. Wait, let's look at the instructions for `write_note`: - One note per theme. - Name and link the actual thing. - Carry 1-2 representative verbatim quotes, copied exactly, each kept with the link it came from. - Then say what it means. - No YAML frontmatter. The title is the first `# ` heading and the slug is the slug parameter. - Stable slugs. Let's write the note for `dram-contract-pricing-skyrockets-to-record-highs-q1-2026` with the title "DRAM Contract Pricing Moderates in Q3 2026 as Consumer Demand Hits Affordability Limits". Let's draft the body carefully. Wait, let's double check if we have the exact quotes and links. - TrendForce Report: [AI Server Demand Continues to Support Memory Prices in 3Q26, but Gains Moderate as Consumer Demand Weakens and High Base Effects Take Hold, Says TrendForce](https://www.trendforce.com/presscenter/news/20260703-13134.html) Quote: "Conventional DRAM contract prices are forecast to rise 13–18% QoQ in 3Q26, while NAND Flash contract prices are expected to increase 10–15%." Quote: "Record-high contract prices mean customers from consumer markets, such as PCs and smartphones, are reaching their affordability limit, leading to more moderate price increases in 3Q26." - Samsung Q2 earnings report: [Samsung says memory shortage will worsen in 2027 as Q2 chip profit hits record](https://mlq.ai/news/samsung-says-memory-shortage-will-worsen-in-2027-as-q2-chip-profit-hits-record/) Quote: "The semiconductor division generated 89.2 trillion won in operating profit; Samsung’s consumer-device division lost 800 billion won as component costs rose." Quote: "Faced with weaker consumer demand, smartphone brands are becoming increasingly conservative in production planning and procurement, which could potentially reduce LPDRAM demand further." (from TrendForce) Let's call `write_note` for `dram-contract-pricing-skyrockets-to-record-highs-q1-2026`.

Now let's update `sk-hynix-overtakes-samsung-market-value-dram-setback`. Let's review the details of SK Hynix's Q2 2026 earnings on July 29, 2026: - Revenue: 79.3187 trillion KRW (+51% QoQ, +257% YoY) - Operating Profit: 60.5426 trillion KRW (+61% QoQ, +557% YoY) - Operating Margin: 76% (up from 72% QoQ) - Net Income: 93.9226 trillion KRW (net margin of 118%) - Cash and cash equivalents: 88 trillion KRW (up 33.6T KRW QoQ), net cash 69.4T KRW. - Capex: Raised 2026 CapEx to the "high KRW 40 trillion range" (~$31-34B) due to schedule acceleration for M15X and Yongin Phase 1 cleanroom. - Nasdaq Listing: Successfully completed its historic Nasdaq ADR listing on July 10, 2026. - HBM4: Mass production began in Q2 2026, with yields already nearing mature HBM3E levels. - LTAs: Finalized LTAs with around 10 customers, including financial mechanisms like customer cash deposits. - Market Reaction: Shares slumped ~9-10% post-earnings because results slightly missed elevated consensus expectations (consensus was ~84T won revenue and ~64T won operating profit). Let's call `write_note` to update `sk-hynix-overtakes-samsung-market-value-dram-setback`. Let's draft the body carefully. Let's write the note.

Now let's update `samsung-vertical-integration-hbm4e-hbm5-leap`. Let's review the details of Samsung's Q2 2026 earnings on July 30, 2026: - Total Revenue: 171.5 trillion KRW (+28% QoQ, +130% YoY) - Operating Profit: 89.5 trillion KRW (up 1,814% YoY) - Semiconductor (Device Solutions) division operating profit: 89.2 trillion KRW on sales of 127.5 trillion KRW. - Consumer-device (Device eXperience) division: Lost 800 billion KRW due to rising component costs (e.g., high memory/DRAM costs). - HBM4 Progress: - Customer qualifications for individual projects are being wound down smoothly. - Expect HBM4 sales to increase by more than three-fold QoQ in Q3 2026. - HBM4 is expected to account for well over 60% of total HBM revenue mix in 2H 2026. - HBM4E Progress: - Shipped industry-first HBM4E samples to major customers. - Established sufficient product competitiveness to commercialize with major customers as planned in 2027. - Supply Deficit: - Memory executive Kim Jaejune said they expect the supply-demand gap to widen further in 2027. - Secure LTAs with five major global data-center customers and discussing more. - Line 5 at Pyeongtaek Campus 2 is scheduled to begin full operations in 2028 as an HBM production center. - Taylor, Texas second fab construction to start before the end of 2026, targeting production in 2030. Let's call `write_note` to update `samsung-vertical-integration-hbm4e-hbm5-leap`. Let's draft the body carefully. Let's write the note.

Now let's update `semiconductor-equipment-re-rating-hbm-complexity-gains`. Let's review the details of ASML and Lam Research Q2/Q4 2026 earnings: - **ASML (July 15, 2026):** - Q2 sales of €9.3 billion and net income of €2.9 billion. - Upgraded full-year 2026 net sales outlook to €43 billion to €45 billion, with a gross margin between 54% and 56%. - Memory-related net system sales are projected to grow by 75% in 2026. - CEO Christophe: "either for DDR or for HBM, there is a clear need for more supply. All of that together means that our revenue on memory this year will increase by 75%." - Memory represented 49% of total net sales in Q2 2026, showcasing how "every memory fab is chasing HBM demand." - **Lam Research (July 29, 2026):** - Record Q4 FY2026 revenue of $5.21 billion (+32% YoY). - Diluted EPS for FY2026 reached a record $5.82 (up 41% YoY). - June quarter systems revenue in memory was 46% (up from 39% in the March quarter). On a dollar basis, this was a record level for Lam in total memory. - NAND revenue dollars more than doubled sequentially, driven by conversions to 256-layer and above class devices, primarily enabling enterprise SSDs. - Tim Archer (CEO) expects Lam's served available market (SAM) per wafer in NAND to double from the 128-layer node to 500-plus layer devices. - DRAM was flat on a dollar basis at record levels (23% of systems revenue). DRAM spending was directed toward wafer additions and technology upgrades (1-alpha, 1-beta, 1-gamma nodes) enabling DDR5, LPDDR5, and HBM. - HBM: Tall stacks increase process times, requiring more equipment for TSV (Through-Silicon Via) formation. - Raised 2026 wafer-fabric-equipment (WFE) spending forecast to the "low-$150 billion range". - For 2027, DRAM is expected to be the fastest-growing WFE segment, followed by leading-edge foundry/logic, then NAND. Let's call `write_note` to update `semiconductor-equipment-re-rating-hbm-complexity-gains`. Let's draft the body carefully. Let's write the note.

Now let's update `micron-scas-business-model-transformation-cyclicality`. Let's review the details of the LTAs and customer cash deposits that have become industry-wide: - **Micron pioneered this with its Strategic Customer Agreements (SCAs)**, signing 16 take-or-pay agreements in Q3 2026, which are projected to bring in $18 billion in customer cash deposits on the balance sheet. - **SK Hynix (July 29, 2026):** Confirmed it has concluded Long-Term Agreements (LTAs) with around 10 major customers. These agreements incorporate financial mechanisms like customer cash deposits to secure mid-to-long-term supply stability and support contract implementation. - **Samsung (July 30, 2026):** Confirmed it has secured multi-year LTAs with five major global data-center customers and is discussing more. - This confirms that the memory industry has undergone a structural shift from a transactional commodity market to a long-term strategic partnership model. Hyperscalers are willing to pay upfront cash deposits to guarantee allocation of HBM4, HBM4E, and server DRAM, which gives memory suppliers unprecedented demand visibility and financial security to fund their massive capex expansions. Let's call `write_note` to update `micron-scas-business-model-transformation-cyclicality`. Let's draft the body carefully. Let's write the note.

This is absolutely spectacular. I have updated all five notes with rich, concrete evidence, direct quotes, and links, integrating the newest information from Samsung, SK Hynix, ASML, and Lam Research. Let's double-check if there are any other threads or watches to record or register. Let's see: Are there any new forward-looking catalysts or tripwires we should watch for? - **Samsung's Taylor, Texas Fab 2 construction start:** Slated to begin construction before the end of 2026. This is a great candidate for a dated catalyst watch. - **SK Hynix's Yongin Phase 1 cleanroom opening:** Scheduled for early 2027. This is another great candidate for a dated catalyst watch. - **Samsung's HBM4 sales in Q3 2026:** Samsung guided for HBM4 sales to increase by more than three-fold QoQ in Q3 2026, and to account for well over 60% of total HBM revenue mix in 2H 2026. We can set up a watch for Samsung's Q3 2026 earnings (around late October 2026) to verify this HBM4 revenue mix. Let's call `record_watch` to register these forward-looking catalysts. Let's register: 1. Samsung's HBM4 sales growth and revenue mix in Q3 2026 (expected to triple QoQ and exceed 60% of total HBM mix). This is a `one_shot` watch with a fire date around November 1, 2026. 2. Samsung's Taylor, Texas Fab 2 construction start (slated for before the end of 2026). This is a `one_shot` watch with a fire date around December 31, 2026. 3. SK Hynix's Yongin Phase 1 cleanroom opening (scheduled for early 2027). This is a `one_shot` watch with a fire date around March 31, 2027. Let's call `record_watch` for Samsung's HBM4 sales growth and revenue mix in Q3 2026 first.

Ah! I missed `watch_type` in the parameters. Let's see: `watch_type` can be one of: `dated_catalyst`, `scheduled_release`, `metric_threshold`, `live_process`, `tripwire`, `thesis_breaker`. For Samsung's Q3 earnings, it is a `scheduled_release`. Let's call `record_watch` again with `watch_type: "scheduled_release"`.

Now let's register the second watch: Samsung's Taylor, Texas Fab 2 construction start. - `watch_type`: `dated_catalyst` - `cardinality`: `one_shot` - `fire_date`: `2026-12-31T00:00:00Z` - Let's call `record_watch`.

Now let's register the third watch: SK Hynix's Yongin Phase 1 cleanroom opening. - `watch_type`: `dated_catalyst` - `cardinality`: `one_shot` - `fire_date`: `2027-03-31T00:00:00Z` - Let's call `record_watch`.

Excellent! All three watches are registered. Now, let's call `finish_cycle` to complete this research cycle. Wait, let's verify if there is any other action needed. No, I have completed all the required tasks: 1. Checked threads and watches. 2. Gathered and confirmed evidence from primary sources (SK Hynix, Samsung, TrendForce, ASML, Lam Research). 3. Updated five existing notes in place using their exact slugs. 4. Resolved the SK Hynix earnings watch thread. 5. Registered three new forward-looking watches with specific catalysts. 6. Now, I will call `finish_cycle` to end the research cycle. Let's do that.

The research cycle is now complete. I will write a final summary of the findings and actions taken. ### Summary of Research Cycle Findings & Actions In this cycle, we tracked the latest developments in the AI-driven memory/storage cycle—including HBM, DRAM, and NAND—by analyzing the July 2026 earnings reports of South Korean memory giants **SK Hynix** and **Samsung Electronics**, lithography leader **ASML**, and etch/deposition specialist **Lam Research**, along with recent contract pricing data from **TrendForce**. #### 1. Action Taken: Resolved Thread - **SK Hynix Q2 2026 Earnings & Capex Guidance** (`019f7e94-2489-70b7-b40e-71acd58bb158`): **Resolved**. Recorded the event showing that SK Hynix reported record Q2 2026 results on July 29, 2026, with revenue of 79.3T KRW (+257% YoY) and an operating margin of 76%. Capex was raised to the high 40T KRW range to accelerate M15X and Yongin Fab 1, and HBM4 mass production commenced in Q2. #### 2. Action Taken: Registered New Watches - **Samsung Q3 2026 HBM4 Sales Growth and Revenue Mix Verification** (Scheduled Release, One-shot, expected November 1, 2026): To verify if HBM4 sales tripled QoQ and exceeded 60% of HBM mix in 2H 2026. - **Samsung Taylor Fab 2 Construction Groundbreaking** (Dated Catalyst, One-shot, expected December 31, 2026): To monitor Samsung's progress in starting construction on its second Texas fab before the end of 2026. - **SK Hynix Yongin Phase 1 Cleanroom Opening and Equipment Installation** (Dated Catalyst, One-shot, expected March 31, 2027): To monitor the opening of SK Hynix's next-generation production hub in early 2027. #### 3. Updated Findings (Living Documents) We updated five key notes in place to reflect the latest sector data: 1. **DRAM Contract Pricing Moderates in Q3 2026 as Consumer Demand Hits Affordability Limits** (`dram-contract-pricing-skyrockets-to-record-highs-q1-2026`): - **What's New:** TrendForce reports that DRAM contract price increases are moderating to 13–18% QoQ, and NAND to 10–15% QoQ in Q3 2026. This is because consumer-facing OEMs (PC/mobile) have reached their "affordability limit." - **Evidence:** Samsung's Q2 2026 results perfectly illustrate this downstream margin squeeze: while its semiconductor division earned a historic 89.2 trillion won in operating profit, its consumer device (DX) division swung to an 800 billion won operating loss due to high component costs. 2. **SK Hynix Overtakes Samsung in Market Value and Launches Historic $26.5B Nasdaq Listing** (`sk-hynix-overtakes-samsung-market-value-dram-setback`): - **What's New:** SK Hynix reported record Q2 2026 earnings on July 29, 2026, but its stock slumped ~9-10% post-earnings as it slightly missed elevated consensus expectations. It raised full-year capex guidance to the high 40 trillion KRW range (~$31-34B) to accelerate M15X and Yongin Phase 1. - **HBM4 Progress:** SK Hynix officially began mass production of HBM4 in Q2 2026, with yields already nearing mature HBM3E levels. 3. **Samsung Leverages Vertical Integration to Leapfrog Competitors in HBM4E and HBM5** (`samsung-vertical-integration-hbm4e-hbm5-leap`): - **What's New:** Samsung posted a spectacular 1,814% YoY operating profit surge to 89.5 trillion KRW in Q2 2026. HBM4 qualifications are wrapping up, with sales projected to triple QoQ in Q3 and account for over 60% of Samsung's HBM mix in 2H 2026. - **HBM4E & Capacity:** Samsung shipped industry-first HBM4E samples and warned that the memory shortage will worsen in 2027. It plans to start construction on Taylor Fab 2 by the end of 2026 and bring Pyeongtaek Line 5 online in 2028. 4. **AI Memory Bottlenecks Drive Epic Valuation Re-rating for Semiconductor Equipment Leaders** (`semiconductor-equipment-re-rating-hbm-complexity-gains`): - **What's New:** The equipment layer is capturing massive value from the memory capex boom. ASML reported strong Q2 results on July 15, 2026, and upgraded its 2026 sales outlook to €43–45 billion, driven by a **75% projected growth in memory-related sales**. - **Lam Research:** Reported record Q4 FY2026 results on July 29, 2026. Sequential growth was propelled by a **doubling of NAND revenue** (driven by 256-layer+ enterprise SSD conversions). Memory represented 46% of Lam's systems revenue. Lam also raised its 2026 global WFE spending forecast to the low-$150 billion range. 5. **Micron Redefines Memory Cycle with 16 Take-or-Pay Strategic Customer Agreements in Record Q3 2026** (`micron-scas-business-model-transformation-cyclicality`): - **What's New:** The long-term contract and upfront cash deposit model pioneered by Micron has officially spread industry-wide. Both SK Hynix (concluded LTAs with ~10 major customers with cash deposits) and Samsung (secured LTAs with 5 major global data-center hyperscalers) have adopted similar frameworks. - **Cyclical Implications:** This universal transition from a transactional commodity market to a long-term strategic partnership model provides the Big Three with unprecedented capex visibility and interest-free funding, suggesting that the eventual downturn will be far more manageable and less destructive than past busts.
