Nanya Technology Corp.: Navigating the Peak of a Specialty DRAM Pricing Cycle

Core Conclusion

Near-term pricing strength for DDR4 memory, driven by a supply deficit, provides a supportive backdrop for Nanya Technology (NTC) in 2026. However, the cycle appears mature; we expect price momentum to slow in 2H26 before declining from 2H27 as new competitor capacity arrives. The current valuation appears to fully discount the positive near-term earnings momentum, leaving limited upside. The risk/reward profile is balanced.

What the Market May Be Underestimating

The market may be underestimating the speed and magnitude of the impending supply shift in 2027. While focusing on the current tightness, investor attention may not have fully priced in the combined impact of competitor CXMT’s capacity additions and NTC’s own new capacity coming online in 2H27, which is projected to reverse the shortage and trigger a price decline.

Evidence Chain

1. The near-term pricing catalyst is strong but recognized. A shortage in the DDR4 market, exacerbated by major global players exiting this segment, is expected to persist into 2H26. This supply-driven dynamic is forecast to push the market from a 12% oversupply in 2Q25 to a 2% shortage by 3Q26, supporting NTC’s pricing power and utilization. The investment implication is that 2026 financials will benefit, a factor already reflected in recent consensus estimate increases.

2. The cycle's maturity is evidenced by extreme price appreciation and capacity plans. DDR4 spot prices have already surged over 700% year-on-year versus February 2025, a trajectory that is inherently unsustainable. Concurrently, competitor CXMT is actively adding capacity, and NTC itself plans to bring new capacity online in the second half of 2027. The investment implication is that the window for price hikes will narrow meaningfully in late 2026, setting the stage for a cyclical downturn.

3. Revised financial estimates confirm near-term strength but highlight a sharp 2028 decline. Following strong 1Q26 results and a long-term agreement (LTA), our 2026-2028 EPS estimates were raised by 14-15%. Despite this upward revision, the model projects a steep 47% year-on-year decline in EPS for 2028, dropping from NT$62.86 to NT$33.50. This forecasts the operational deleverage and margin pressure expected as the cycle turns, capping long-term earnings power.

Key Disagreements and Risks

The primary risk is the sustainability of the current specialty DRAM pricing cycle. An upside risk involves sustained pricing strength from more disciplined industry supply or stronger-than-expected demand. The predominant downside risks are a faster-than-expected ramp of competitor capacity, which would accelerate price declines, or weaker demand for applications like 4K TVs and set-top boxes.

Valuation and Trading Implications

We maintain an Equal-weight rating with a NT$278 price target, implying ~26% upside from the current level. This target is based on a P/B valuation of 2.54x 2026e book value. We argue this multiple—above the stock's +1 standard deviation level of 2.2x—already incorporates the near-term earnings boom. Assigning a higher multiple is unjustified given the expected cyclical peak and subsequent pressure from new supply. The stock appears fairly valued for the current phase of the cycle.
