Original: 崇越 5 月份營收達 65.4 億元，前五個月營收為 318.5 億元年增 17.6%
Topco Scientific, a Taiwanese semiconductor materials integrator, posted May 2026 revenue of NT$6.54B (+18.6% YoY), the third-highest monthly figure on record, with Jan–May revenue at NT$31.85B (+17.6% YoY). Growth is driven by AI/HPC pull on advanced-node materials (photoresist, FOUP, slurry, quartz) supplied to TSMC and other foundries running at high utilization.
Why it matters: Monthly revenue print from a semi-materials supplier confirms strong advanced-node materials demand at TSMC, but Topco itself is not in the tracked universe — read-through is sector/supply-chain signal rather than a stock-moving event for tracked names.
Original: 旺宏 5 月營收及累計全年前五個月營收，雙雙創下歷史新高
Macronix reported May 2026 revenue of NT$6.26B (+5.8% MoM, +175.8% YoY), with 5M26 cumulative revenue of NT$22.64B (+110.9% YoY) — both record highs. Brokers expect Q2 revenue of NT$18.98B (+81% QoQ) and GM of 64.5%, driven by Kioxia/Micron exiting SLC NAND and tight NOR Flash supply pushing contract prices up nearly 100% QoQ. Read-through is positive for Korean memory peers exposed to NAND/NOR pricing cycles.
Why it matters: Record monthly revenue plus broker forecast of ~100% QoQ contract price hikes in NOR/SLC NAND on Kioxia/Micron exits is a clear stock-moving memory pricing signal with read-through to Korean peers.
Open source articleOriginal: 營收速報 - 京元電子(2449)5月營收37.77億元年增率高達36.61％
Taiwan's King Yuan Electronics (KYEC, 2449-TW) reported May 2026 revenue of NT$3.78B, up 36.6% YoY and 0.9% MoM, with YTD revenue at NT$17.71B (+37.7% YoY). The strong test/OSAT demand signals continued AI-driven backend capacity tightness, a positive read-through for testing peers and HBM/AI accelerator supply chains. Shares closed at NT$288.5, down 5.8% over the past 5 sessions despite foreign net buying of +22,044 lots.
Why it matters: Monthly revenue print from a non-universe Taiwanese OSAT/test house — a sector data point on AI backend demand rather than a direct catalyst for any tracked ticker.
Open source articleOriginal: 威剛5月營收又飆高至129.4億元 連三個月改寫新高
Taiwan memory module maker ADATA (3260-TW) posted May revenue of NT$12.94B (~US$400M), +22.6% MoM and +210% YoY, marking a third consecutive monthly record; 5M YTD revenue of NT$49.6B already nears full-year 2025. Chairman Chen Li-Pai sees DRAM/NAND contract prices continuing to rise into 2027 on AI datacenter and Vera Rubin platform demand, and is building inventory to over NT$50B by 3Q — a bullish read-through for upstream DRAM/NAND suppliers Samsung and SK Hynix.
Why it matters: Record revenue from a major memory module maker plus explicit guidance that DRAM/NAND contract prices and shortages will intensify into 2027 is a clear positive read-through for upstream Korean DRAM/NAND suppliers.
Open source articleOriginal: 威剛 5 月營收 129.4 億元續創歷史新高，累計前五個月達 2025 年全年 93%
ADATA posted record May revenue of NT$12.94B (~US$400M), up 210% YoY and 23% MoM, with 5M26 revenue already at 93% of full-year 2025. Chairman Chen Li-Pai sees DRAM/NAND contract prices continuing to rise, expects Q3 inventory to exceed NT$50B (~US$1.5B), and warns shortages will intensify into 2027 — bullish read-through for upstream DRAM/NAND suppliers Samsung and SK Hynix.
Why it matters: Single-company monthly revenue print from a Taiwan memory module maker, but the bullish DRAM/NAND pricing and 2027 shortage commentary provides supply-chain read-through for upstream Korean memory makers.
Open source articleOriginal: 營收速報 - 奇鋐(3017)5月營收158.71億元年增率高達60.64％
Taiwan thermal-solutions maker Auras Technology (3017) reported May 2026 revenue of NT$15.87B (~US$510M), up 60.6% YoY and 1.5% MoM, with YTD revenue of NT$80.54B (+90.3% YoY). The blistering growth signals sustained AI server liquid-cooling and heatsink demand, a positive read-through for the broader AI infrastructure supply chain including GPU server ODMs and HBM suppliers.
Why it matters: Monthly revenue print from an AI server thermal-solutions vendor not in the tracked universe; serves as a supply-chain demand indicator rather than a direct stock-moving event for covered names.
Open source articleOriginal: 營收速報 - 廣達(2382)5月營收3,114.81億元年增率高達94.38％
Quanta reported May 2026 revenue of NT$311.48B (~US$10.4B), up 94.4% YoY but down 8.4% MoM, with YTD revenue reaching NT$1.46T (+82.6% YoY). The blowout print confirms sustained AI server ODM momentum and reads positively for the broader Taiwan AI server supply chain including peers and upstream component makers.
Why it matters: Monthly revenue print with ~94% YoY growth from a top AI server ODM is a clear stock-moving datapoint with read-through to the broader AI server supply chain.
Open source articleOriginal: 營收速報 - 旺宏(2337)5月營收62.56億元年增率高達175.8％
Macronix (2337-TW) reported May 2026 revenue of NT$6.26B, up 175.8% YoY and 5.8% MoM, with YTD revenue reaching NT$22.64B (+110.85% YoY). Foreign investors net bought 24,158 lots over the past 5 days, though shares fell 9.91% in the same period to NT$143.5. The NOR/NAND flash memory recovery signals broader demand strength relevant to Korean memory peers.
Why it matters: Macronix isn't in the tracked universe, but the 175.8% YoY revenue surge signals a broader NOR/specialty flash memory cycle recovery that supports read-across to Korean memory names like Samsung and SK Hynix.
Open source articleOriginal: 全球百大企業排名調查，台積電市值翻倍躍居第九名
PwC Taiwan's 2026 Global Top 100 ranking (as of March 31, 2026) shows TSMC climbing from 12th to 9th with market cap doubling YoY (+101%) to $1.43T, the highest growth among the top 10. TSMC is the only Taiwanese name on the list, lifting Taiwan's country ranking from 7th to 4th globally, behind only the US, China, and Saudi Arabia. The report attributes the surge to sustained AI and semiconductor demand, with IT sector market cap up 34% YoY to $18.69T.
Why it matters: Backward-looking ranking/market-data story rather than a fresh fundamental catalyst, but directly highlights TSMC's AI-driven re-rating and Taiwan's semi supply-chain leverage.
Original: 〈台股盤後〉創史上第3大跌點1568點但守住4萬3 連跌3天近3000點
Taiex tumbled 1,568.16 points (-3.48%) to 43,502.78 on Monday, the 3rd-largest point drop in history, with three-day losses totaling 2,956 points after Friday's US selloff hit AI/tech names. TSMC (2330) fell 2.96% to NT$2,295, MediaTek (2454) and Hon Hai (2317) hit limit-down intraday, ASE (3711) -6%, while silicon photonics names (4977, 4908, 4979) locked limit-down on US optical weakness. Counter-trend gains came from May-revenue-record names and passive-component plays on price-hike themes.
Why it matters: Broad market selloff with named index-heavyweight moves (TSMC, MediaTek, Hon Hai, ASE) and a clear silicon-photonics subsector wipeout — sector/market-data story rather than a single stock-moving catalyst.
