Memory Chip Price Gains Stall, Triggering Debate on Supercycle Peak

Key points

• DDR4 contract prices reached an all-time high of $26 in September but rose only 4%, down from 14.29% in July.
• NAND flash prices for 128Gb MLC were $30.61 in September, up just 0.44%, after a steep decline from 36.29% in April.
• Micron reported fiscal Q4 revenue of $54.23 billion and adjusted EPS of $33.42, but the earnings beat was only 6%, compared to 31% in the prior quarter.
• Long-term supply agreements (LTAs) are limiting how quickly high market prices translate into earnings for chipmakers.
• TrendForce forecasts Q4 DRAM prices will rise 10-15% and NAND prices 15-20%, driven by AI server demand.
• Samsung Electronics is expected to release preliminary Q3 results on October 8, with consensus operating profit at 105.6 trillion won.

Background

Micron's stock has surged 552% over the past year, reaching a record $1,000 barrier in September 2026. Despite record earnings reported on October 2, the stock declined 1.5% to $1,080.89 as investors questioned the sustainability of high margins. The company has previously split its stock three times, but no new split has been announced. Intel warned in September that memory shortages could worsen, supporting pricing power, but recent data suggests the pace of price increases is slowing.

How outlets are covering it

Seoul Economic Daily emphasizes the deceleration in price gains and the impact of long-term agreements on earnings volatility, noting that Micron's earnings surprise narrowed to 6%. The outlet highlights that while prices are at all-time highs, the momentum is fading, with NAND flash prices nearly flat. Yahoo Finance, through its market data, shows Micron's stock trading at $1,080.89, reflecting investor skepticism despite record revenue. The two sources agree that the market is shifting focus from price levels to the durability of profits, with Samsung's upcoming results seen as a key test for the sector.

Why it matters

The slowdown in memory price gains could signal a peak in the current supercycle, affecting profitability for major chipmakers like Micron and Samsung. If long-term supply agreements continue to limit price transmission, high margins may not sustain the current stock valuations. Investors are watching Samsung's Q3 results and Q4 price forecasts to determine whether the AI-driven demand will maintain the supply shortage or if a correction is imminent.

What to watch

Samsung Electronics will release preliminary third-quarter results on October 8, 2026. TrendForce forecasts Q4 DRAM prices to rise 10-15% and NAND prices 15-20%, but the actual impact on earnings will depend on the share of long-term agreements. Micron's CEO Sanjay Mehrotra stated that demand will exceed supply in 2027 and 2028, but the timing of a supply-demand balance remains uncertain. Market attention will focus on whether high operating profits can be sustained or if a 'peak-out' is imminent.
