DayStarter

How a memory shortage turned a cyclical chipmaker into a trillion-dollar company

DayStarter, Vol. I, No. 91, by Devraj Pant. Indian markets opened higher but lost momentum: the Nifty 50 opened at 23,454, briefly recovered towards 23,400 after reports of discussions on reopening the Strait of Hormuz, and ended at 23,329, down 0.36% and around 125 points below its opening level; the Sensex closed at 74,529.08, down 329.91 points or 0.44%. The broader market held up better than the large-cap index, with Nifty Microcap 250 up 0.4%. Eleven of the 15 sector indices fell, with Media the strongest at 1.2% and IT the weakest at -0.9%. Crude oil fell below $91 per barrel to a more than two-week low in its fifth straight session of losses, the rupee strengthened to 95.63 per US dollar, and on 22 September foreign investors were net sellers of 675 crore rupees while domestic institutions were net buyers of around 4,100 crore rupees. In macro news, the RBI and finance ministry asked banks to ensure ATM cash from 15 October when a 0.4% UPI merchant discount rate on person-to-merchant payments above 2,000 rupees begins, Jio-bp capped diesel sales, the India-New Zealand FTA comes into force next month, and jobs data showed only around 47% of young adults in poll-bound states are employed. Corporate news centred on a Tata Sons and TVS Motor governance investigation, LIC's roughly 4,500 crore rupee bid in NSE's $2.4 billion IPO which was subscribed 5.7 times, and new IPO filings. Global markets were led by AI-related gains, with the Nasdaq Composite at a record high, Meta up 11% and AMD crossing $1 trillion. The feature examines how a memory shortage turned Micron Technology, which closed at $1,096.16, into a company worth around $1.24 trillion, with revenue up 346% year-on-year and a gross margin of 84.9%, ahead of its 30 September fiscal fourth-quarter results.

  • UPI MDR: A 0.4% merchant discount rate will apply to person-to-merchant UPI payments above ₹2,000. The charge is capped at ₹300 for transactions of ₹75,000 and above. Person-to-person transfers remain free.
  • Most payments remain exempt: Around 96% of P2M UPI transaction volume is below ₹2,000 and will stay outside the MDR framework.
  • ATM network: The number of ATMs fell to 2,51,057 by end-March 2025 from 2,53,417. Public sector banks had 1,33,544 ATMs, private banks 77,117 and white-label operators 36,216.
  • Cash remains important even as digital payments grow. Currency in circulation was ₹42.86 trillion at end-August 2026, up 12.5% year-on-year. UPI processed 2,451 crore transactions worth about ₹29.82 trillion in August.

Energy and infrastructure

  • Diesel curbs: Jio-bp capped diesel sales at 50 litres per customer per transaction and 6,000 litres a day at each of its 2,000 outlets across 21 states and union territories.

  • Brent crude has remained above $100 a barrel for weeks and touched a four-month high of $110 on 14 September.
  • Aviation policy: The Centre is considering whether airport operators such as Adani Airport Holdings should be allowed to own airlines. Delhi and Mumbai airport operators can currently hold up to 10% in an airline under their operating agreements.

Micron Technology: How a memory shortage turned a cyclical chipmaker into a trillion-dollar company

Micron Technology closed at $1,096.16 on 22 September, up 5% for the day. The 48-year-old memory-chip company is now worth around $1.24 trillion. Its share price has changed dramatically, but the bigger change is visible in the economics of the business.

The run

Over the past 52 weeks, Micron traded between $154.65 and $1,255.00. By 4 September, the stock was up 256% for the calendar year. By 9 September, it was up 724% over twelve months. Over three years, the share price increased around 13.7 times.

The path was volatile. Micron fell 7.02% on 18 August, 4.90% on 10 September and 5.25% on 14 September. It then rose around 14% over the three trading days through 21 September after Stifel's Brian Chin repeated a Buy rating with a $1,500 price target. Micron's beta is 2.22, meaning the stock has historically moved more than twice as much as the broader US market. Tuesday's gain came as memory shares rose on renewed AI optimism and a sharp fall in oil prices.

For most of its history, Micron was a classic cyclical business. Memory chips behave like commodities: profits rise quickly when prices are strong and can collapse when prices fall. The present valuation reflects a market view that the structure of the business may be changing.

What Micron makes

Micron mainly makes DRAM and NAND memory. DRAM is fast, temporary working memory used by processors while they calculate. It loses its data when power is turned off. NAND is storage memory used in SSDs and phones and keeps data after power is removed. Micron also sells NOR flash. The company was founded in 1978 and employs around 53,000 people.

The product at the centre of the current cycle is high-bandwidth memory, or HBM. HBM is a type of DRAM where memory dies are stacked vertically and placed close to an AI accelerator such as an Nvidia GPU. AI systems need very large amounts of data to move to the processor quickly, and HBM provides that bandwidth. Only SK Hynix, Samsung and Micron produce HBM at scale. IDC estimates the same three companies control more than 95% of global DRAM production.

In the quarter ended 28 May 2026, DRAM generated $31.3 billion, or 76% of Micron revenue. NAND generated $9.9 billion, or 24%.

Why the shortage matters

AI demand is part of the story, but the tighter constraint is supply. HBM uses around three times the wafer capacity of standard DRAM per bit, according to a Micron executive. Wafer capacity is scarce. When capacity is moved to HBM for AI accelerators, less capacity is available for ordinary DDR5 and DDR4 memory used in servers, laptops, phones and cars. HBM also sells at higher prices and margins, so Samsung, SK Hynix and Micron have all shifted more production towards it.

Three factors made the shortage worse. First, memory companies cut output and delayed expansion during the 2022-23 downturn, so the industry entered the AI boom with limited spare capacity. Second, new semiconductor fabs take years to build, and new capacity from Micron and SK Hynix is not expected to reach volume production before 2027 at the earliest. Third, hyperscalers including Meta, Google, Microsoft and Amazon began signing long-term supply agreements, locking up production for years.

Micron CEO Sanjay Mehrotra said the company could meet only 50% to two-thirds of customer demand in the medium term. Samsung and SK Hynix saw finished DRAM inventory fall below 10 days of supply on 7 September. Intel CEO Lip-Bu Tan said memory prices had risen five to seven times. The shortage allowed memory producers to raise prices sharply and expand margins.

Operating leverage: why profits moved much faster than revenue

Memory manufacturing has very high fixed costs. Fabs, equipment and engineering teams cost roughly the same whether memory prices are strong or weak. When prices rise, a large part of the extra revenue can therefore flow into profit. Micron shows this clearly.

Micron Q3 FY26 results release

Revenue rose 346% year-on-year, while cost of goods sold increased only from $5.79 billion to $6.40 billion. Nearly the entire $32 billion increase in revenue therefore became gross profit, which rose from $3.51 billion to $35.06 billion. This is operating leverage: earnings per share rose around thirteen times while revenue rose around four-and-a-half times. The move towards HBM4, which Micron is shipping to its lead accelerator customer and on which it has booked more than $1 billion of revenue, has been identified as the most important driver of the margin expansion.

Three years ago, Micron lost $5.83 billion in a year as revenue almost halved. Consensus now expects net income of $82.98 billion for the fiscal year that ended in August.

From cycle to contract

Micron's sales model is also changing. Alongside its June results, the company announced 16 multi-year Strategic Customer Agreements with at least approximately $100 billion of contracted revenue. Data-centre revenue exceeded $25 billion in the quarter, equal to an annualised run rate above $100 billion.

“We believe our multi-year Strategic Customer Agreements will significantly enhance the durability and predictability of Micron's strong financial performance.”
Sanjay Mehrotra, CEO, Micron

The balance sheet strengthened at the same time. Long-term debt fell from $14.02 billion in August 2025 to $5.14 billion in May 2026, while cash and investments reached $30.2 billion. Consensus FY27 EPS rose from around $102.72 to $155.03 during the 90 days to early September. Among 49 analysts polled by S&P Global, the average one-year target price is $1,515.

The India connection

Micron's supply chain now includes Gujarat. Its assembly and test plant in Sanand has a combined investment of around $2.75 billion with government partners. Micron's own contribution is up to $825 million across two phases. Commercial production began in February 2026 and the facility was inaugurated by Prime Minister Narendra Modi. It was the first proposal approved under the India Semiconductor Mission.

The Sanand plant does not manufacture wafers. It takes DRAM and NAND wafers produced elsewhere in Micron's network and turns them into finished memory products through assembly and testing. The first shipment of made-in-India memory modules went to Dell Technologies. Micron expects to assemble and test tens of millions of chips in Sanand during 2026 and hundreds of millions in 2027. The company also has engineering and design teams in Bengaluru and Hyderabad.

What could weaken the story

  • China's CXMT: The Chinese DRAM manufacturer moved its fifth-generation process into mass production with at least 50% more dies per wafer. It held around 9.5% of global DRAM revenue in the second quarter. The main risk is a shorter period of scarcity rather than an immediate price collapse.
  • Memory's history: Micron's FY23 loss is a reminder that memory prices can reverse quickly. Checks cited by UBS suggest the present shortage could last through calendar 2027 and into 2028, but the industry has repeatedly moved from shortage to oversupply in previous cycles.
  • Valuation disagreement: Analyst price targets range from $361 to $2,200. Goldman Sachs has a Hold rating with a $1,100 target, close to the current share price.
  • Forward multiple: Micron trades at around 24.7 times trailing earnings but only around 7.5 times forward earnings. The low forward multiple reflects uncertainty about how long current memory prices and margins can last.
  • Demand fulfilment: Micron CEO Sanjay Mehrotra has said the company can meet only 50% to two-thirds of customer demand in the medium term.

What to watch on 30 September

Micron reports fiscal fourth-quarter results on 30 September. Management has guided to revenue of $50 billion plus or minus $1 billion, a gross margin of around 86% and earnings per share of $31.00 plus or minus $1.00. The market consensus is around $50.59 billion of revenue and $31.27 of adjusted EPS. The main questions are whether contract prices are still rising or have stabilised, how quickly HBM4 production is increasing, how much new capacity Micron plans to add, and how durable management believes its long-term supply agreements will be.
