Nanya Technology delivers strong short-term earnings, but stock upside is limited

Overview

This report is Morgan Stanley’s earnings commentary on Nanya Technology Corp. The firm says the company delivered strong Q1 performance, with ASP rising over 70% QoQ and operating leverage pushing earnings above expectations. The company stabilized revenues by signing LTAs of varying maturities and is strengthening customer collaboration in AI eSSD and networking supply chains. However, the firm maintains an Equal-weight view because DDR4 price gains may slow after Q2 2026, and valuation and earnings re-rating upside are not sufficient to support a clear further rise in the stock.

Core views

The core thesis is: first, Nanya Technology still benefits in the short term from a DRAM supply-driven up-cycle, as major memory vendors exiting DDR4 support the company in offsetting competition from CXMT; second, LTAs help lock in part of profits and improve revenue visibility, but because they do not cover full supply, actual demand still needs to be monitored; third, the YoY DDR4 price increase is already high, and the report expects monthly price rises to peak in Q2 2026; fourth, P/B valuation and the breadth of earnings revisions indicate limited room for additional stock upside, so Equal-weight is maintained.

Analysis framework

The report combines earnings decomposition, pricing-cycle assessment, LTA revenue stability analysis, capex planning, and a P/B valuation framework. On the earnings side, it focuses on ASP, margins, and operating leverage. At the industry level, it evaluates DDR4 supply exits, CXMT competition, new capacity additions, and end-market demand. On valuation, it uses 2026e/2027e BVPS-based P/B multiples to gauge the reasonable share price range.

Methodology notes

• Valuation frameworkPB valuation

  Price-to-book valuation based on book value per share

  The base-case in the report expects the stock to trade at 2.71x/1.51x 2026e/2027e BVPS levels, above average since 2015, and uses this to judge that stock upside is constrained.

  Coverage target

  Strengths

  Benefits from the DRAM supply-driven up-cycle, exit of major DDR4 suppliers, sharp ASP gains, improved operating leverage, and income stability from LTAs.

  Weaknesses

  Valuation is already above long-term averages, the breadth of earnings upgrades is limited, and DDR4 pricing momentum may slow after Q2 2026.

  Comparison

  Compared with the supply contraction from major memory vendors exiting DDR4, the company can currently offset the competitive impact from CXMT in the near term; however, new capacity additions and delayed DDR4 EOL may constrain future pricing.

  Risks

  If DRAM prices no longer persist, if 1a/1b nm ramp-up is slower than expected, or if niche DRAM demand is weaker than expected, both earnings and valuation may come under pressure.

Key data

• Report date2026-04-13Report release time is April 13, 2026 10:53 AM GMT.
• Q1 ASP changeover 70% Q/QThe upside surprise in Q1 earnings was mainly driven by ASP rising over 70% QoQ and operating leverage.
• Q2 pricing outlookaround 46% Q/QThe report model expects pricing momentum to continue in Q2, with QoQ growth of roughly 46%.
• DDR4 price change750% Y/YMorgan Stanley expects DDR4 monthly price hikes to peak in Q2 2026, after having risen around 750% year over year before that.
• Capex planraised from NT$50bn to NT$52bnManagement slightly increased capex and believes there is still room for further upward adjustment.
• Valuation multiple2.71x/1.51x 2026e/2027e BVPSThe base-case P/B valuation is above the average level since 2015.

Impact & implications

The implication for investors is that Nanya Technology’s short-term earnings and cash-flow visibility improved, and LTAs reduced part of the impact from spot price volatility, but the investment thesis has shifted from rapid price upside to the durability of pricing, capacity release, and valuation digestion. If DDR4 price increases slow after Q2, the stock may find it harder to continue benefiting from both earnings upgrades and valuation expansion.

Risks

• Upside risk includes DRAM prices continuing to rise due to more disciplined supply and stronger demand.
• Upside risk includes a stronger pricing environment driving revenue guidance above expectations.
• Upside risk includes 1a/1b nm ramp-up progressing faster than expected.
• Downside risk includes 1a/1b nm ramp-up progressing slower than expected.
• Downside risk includes weaker than expected niche DRAM demand from 4K2K TVs and smart set-top boxes.
• Downside risk includes new capacity additions and delayed DDR4 EOL potentially limiting DDR4 pricing in 2026-2027.

What to watch

• Whether DDR4 monthly price increases peak as expected after Q2 2026.
• LTA coverage ratio, tenor profile, and the impact on actual demand forecasts and inventory behavior.
• Whether the Q2 assumption of about 46% QoQ price growth is achieved, and whether margins remain above Q1.
• Whether NT$52bn capex is raised further and the related cash needs of new plants.
• Progress of 1a/1b nm ramp-up.
• The pace of CXMT competition, new capacity additions, and major memory vendors exiting the DDR4 market.
