麦格理维持南亚科跑赢大盘评级、目标价上调23%至新台币681.4元，大幅上调2026–2028年EPS预期
真正的催化（3Q26营收环比+62%、毛利率85.7%、4Q继续涨价）是公司10月12日法说披露的一手事实，当日已被TrendForce、Sina/IT之家、GuruFocus等广泛传播并经历了一个完整交易日；麦格理此条信号是盘后（台北时间10月13日01:14）卖方跟进的评级重申（评级未变，仅上调目标价/EPS），不带来新的公司层面事实。叠加行情工具故障、无法可靠确认收盘价与法说后实际反应，次日开盘买入属于在已充分公开的财报后追高，缺乏可验证的正edge与可执行价位。

不做 南亚科技（2408.TW）
麦格理研报是10月12日法说后的卖方衍生品（评级未变、仅上调目标价/EPS），核心财报事实（ASP环比+60%、毛利率85.7%、4Q续涨）当日已公开并广泛传播、经历完整交易日；行情工具故障无法核验收盘价与次日跳空幅度，台股T+2且±10%涨跌停，次日开盘追高缺乏可验证edge与可靠限价/止损锚点，不做。

结论摘要
南亚科3Q26业绩（毛利率85.7%、ASP环比+60%、4Q续涨）确实极强且DRAM上行周期延续至2028年，但该等事实10月12日法说当天已公开并被广泛报道、经历完整交易时段；本条麦格理研报仅为盘后卖方重申与目标价上调，属衍生品，且无法核验实时价格，不构成新的可交易edge，故回避追高。
消息传播链
- 麦格理盘后发布研报维持Outperform、目标价上调23%至NT$681.4、EPS上调35–48%，系对当日法说的卖方跟进，评级本身未变。
- 南亚科10月12日法说披露3Q DRAM ASP环比涨超60%、毛利率85.7%，并预期4Q价格继续上涨；核心一手事实当日已公开。
关键理由
- 基本面方向明确为正：3Q26毛利率85.7%、营收同比约+611%、麦格理预期DRAM严重缺货持续至2028年，2026/27年现金流强劲改善资产负债表
- 但催化的一手来源是10月12日法说而非本研报；目标价NT$681.4相对网页显示的约NT$535股价虽有约27%空间，但这是长期目标价而非短线事件收益
主要风险
- 财报与ASP暴涨为10月12日已公开信息，10月13日开盘可能大幅高开后低走（台股T+2、±10%限制下追高风险大）
- 行情工具故障导致无法核验确切收盘价、盘中反应与次日跳空幅度，无法设定可靠限价与止损
反向证据
- 做多前查反向 · 来源 web · 日期 2026-10-12 · 影响 weakens
财报当日股价仅小幅波动（约523–535区间，相对10月9日527变化不大），在85.7%毛利率爆炸式数据下反应温和，可能反映利好已被提前消化或等待次日重估，方向不确定。

麦格理自身将主要风险列为本轮DRAM上行周期的持续性，且目标P/E倍数由6.5x下调至5.5x以反映4Q起涨价放缓，提示周期见顶节奏风险。

先例如何影响了这次决策
对本次决策的影响:先例缺失叠加价格不可核验，支持降低置信度并回避，而非在无锚点情况下追开盘。
方向:无可用对齐先例：行情工具故障导致无法对历史同类台股存储股财报后卖方上调目标价事件计算可靠事件窗口收益。
涨幅量级:未能用aligned先例校准幅度；网页显示股价约NT$523–535、9月18日曾单日+7.58%，说明板块波动剧烈但不能作为本次tp依据。
形态:无法系统验证财报后见光死模式；核心数据当日已交易是更直接的回避依据。

• We reiterate our Outperform rating on Nanya Tech as we remain bullish on the DRAM cycle through 2028.
• 2Q26 ASPs were up 60%+ QoQ, and 3Q sales were up 62% QoQ without meaningful bit growth.
• In our view, the key risk is the longevity of the current strong DRAM upcycle. We expect severe DRAM supply shortages through 2028.
2026 memory sold out; DRAM prices continue to rise
Once again Nanya Tech's sales (3Q26) beat Bloomberg consensus by double-digits. Likely Nanya's 3Q ASP jump was higher than its larger competitors as some semi-annual contracts were updated ahead of 3Q. We do expect further price increases in 4Q26 and 2027 albeit at a much more moderate pace. In addition to higher ASPs, we expect depreciation to decline in 2026. We expect capex to rise in 2027 from 2026's guide of up to "~NT$52bn", and its new fab is scheduled to be ready for equipment move-in starting from 1Q27. In addition to strong earnings momentum, we expect strong positive cash flow to improve the company's balance sheet substantially in 2026/27, supporting funding for the new fab equipment ramp-up.
The transition to the self-developed 1B technology is progressing, with DDR5 already contributing approximately 10% of sales. Although DDR4 margins, which currently account for the majority of current sales, remain the main driver of earnings, we believe greater product flexibility will be important in adapting to future market trends and supporting margins. In addition, Nanya plans to begin ramping up its new fab in early-2027, which we expect will restart sequential bit growth from 2H27.
The company will report 3Q26 earnings on 12 October.
Earnings changes
We raise 2026E/2027E/2028E EPS 35%/46%/48%, to reflect higher ASP assumptions and incorporating actual 3Q26 sales.
Valuation
We raise our target price 23%, to NT$681.4 (5.5x 2027 PER) from NT$552.0 (6.5x 2027E PER). We use a slightly lower P/E multiple on decelerating ASP hikes expected from 4Q26.
Catalysts
Continued strong sales momentum and sustainable high margins over the next several quarters.
Investment Thesis and Recommendation
We remain bullish on the DRAM industry long term and believe Nanya's launch of 10nm-class products should improve its product mix and support cost and profitability long term.
