MCAFax is not a lender or a law firm. --- Rohm Co. (Tokyo Stock Exchange: 6963), the Kyoto power-chip maker, closed at 3,903 yen on October 20, 2026. Blue Orca Capital, a fund best known for short reports, says it is long Rohm because its stake in the 2023 Toshiba buyout could return 8.5x to 17.5x its cost after tax, value the market has not priced. The catalyst Blue Orca points to is a future Toshiba relisting, which Bloomberg has reported could come as early as fiscal 2028. *This is journalism and commentary, not investment advice. We hold no position unless stated.* ## Key facts - **Ticker and exchange:** Rohm Co., Ltd., 6963, Tokyo Stock Exchange Prime (Yahoo: 6963.T). - **Situation type:** hidden asset; a private-equity stake carried near cost on the balance sheet. - **The call:** long, from Blue Orca Capital, pitched at Sohn Tokyo on October 16, 2026 and posted on X on October 19 (US time). - **The stake:** Rohm committed 100 billion yen as a limited partner and 200 billion yen in preferred stock to the Toshiba buyout vehicle in 2023. - **Price:** 3,903 yen at the October 20, 2026 close, about 1.5 trillion yen of market value on our math (386.0 million shares outside Treasury). - **Also named:** Chubu Electric Power (9502) and TRE Holdings (9247), the other two of Blue Orca's "Toshiba Three." - **Main risk:** the stake is private and illiquid, and much of its value rides on Kioxia shares, which have been volatile. ## Is 6963.T a good bet right now? The case for Rohm is that investors may be valuing a struggling chip business and ignoring a large private stake. The case against is that the stake cannot be sold or marked to market until Toshiba lists again. Rohm's own numbers show why sentiment is weak. For the year ended March 31, 2026, Rohm Co. Reported net sales of 481.1 billion yen, up 7.3%, but a net loss of 158.4 billion yen after 193.6 billion yen of impairment losses, mostly on its silicon carbide (SiC) business. The stock has also been falling. Rohm closed at 5,096 yen on October 8, 2026, so the October 20 close is about 23% lower. That drop came during a global AI and chip selloff that [CNBC](https://www.cnbc.com/2026/10/15/sk-hynix-samsung-softbank-stocks-asia-tech-rout-ai-funding-worries.html) reported hit Japanese names such as Advantest and Renesas. ## Why are investors bullish on Rohm? - **Toshiba has turned.** Toshiba's [FY2025 results](https://www.global.toshiba/content/dam/toshiba/ww/ir/corporate/finance/pdf/tpr2025q4e.pdf) show record net income of 1,967.3 billion yen, driven largely by gains on its Kioxia shares. - **Kioxia sales raised cash.** Toshiba cut its Kioxia stake to 12.84% as of September 7, 2026, raising about 360 billion yen in the latest sales, [Seoul Economic Daily](https://en.sedaily.com/international/2026/09/16/toshiba-sells-kioxia-shares-as-stock-rallies-raising-360) reported, citing Nikkei. Toshiba says Kioxia sales sped up its debt repayment. - **The stake is carried at cost.** Blue Orca says the market misses the value because Toshiba LP investments sit on balance sheets "[at cost less returned capital](https://x.com/blueorcainvest/status/2112303004301017579)." - **The core business may inflect.** Blue Orca expects upward revisions to FY3/27 estimates and [cites](https://x.com/blueorcainvest/status/2112303006528176576) Rohm's work with Nvidia on 800V DC power for AI data centers. ## Who's making this call and why? Blue Orca Capital was founded by Soren Aandahl in 2018 and is known for short reports on companies such as Teladoc and Sun Communities. In an [X thread](https://x.com/blueorcainvest/status/2112302980011876638) on October 19, 2026, the fund said the three companies hold Toshiba stakes "that could be worth 80-96% of their current market cap." In the same thread, Blue Orca [estimated](https://x.com/blueorcainvest/status/2112303007987650679) Rohm's upside at "51% to 144%," depending on the value of Rohm's core chip business, Toshiba and Kioxia. Blue Orca discloses that it is long and may trade at any time. **Track record.** Blue Orca Capital is not yet on our scoreboard, so it has no scored record. See the [scoreboard](https://mcafax.com/notebook/market-calls-scoreboard). **Other voices:** - **Senjin Capital's Jamie Halse** made a similar point in a [March 2026 post](https://senjincap.com/a-rare-unsolicited-takeover-offer-within-the-japanese-establishment-denso-rohm/) about Denso's bid for Rohm. He wrote that the bid "likely significantly undervalues Rohm," because Rohm's 14% Toshiba stake was booked at only 100 billion yen. - **Two tracked accounts reposted the idea.** [Deep Sail Capital](https://x.com/DeepSailCapital/status/2112306882719154306) and [Japan Deep Value](https://x.com/JapanDeepValue1/status/2112376978083033504) both reposted Blue Orca's opening post on October 19-20, 2026. Reposts are not written endorsements. ## Who disagrees? We found no detailed public rebuttal on X. The bear case comes from the facts. - **No exit yet.** [Bloomberg](https://www.bloomberg.com/jp/news/articles/2026-03-06/TBD0N7T96OSH00) reported on March 6, 2026 that Toshiba is considering a relisting as early as fiscal 2028, which runs from April 2028 to March 2029. That is a long wait. - **Kioxia swings.** Kioxia (285A) closed at 17,900 yen on October 8, 2026 and 13,140 yen on October 20, about 27% lower. Blue Orca's own range runs from Kioxia down 50% to its 52-week high. - **Denso walked away.** Denso withdrew its proposal to buy Rohm shares on April 28, 2026, after Rohm's board and special committee had not agreed to support it, Rohm [disclosed](https://fscdn.rohm.com/en/financial/ir-news-releases/260428_news1_en.pdf). One possible buyer is gone. - **Leverage.** Rohm funded its 2023 Toshiba investment with bank borrowing, according to its [September 2023 notice](https://micro.rohm.com/en/financial/ir-news-releases/230922_news_en.pdf). ## What are the key facts to verify? - Rohm's [July 2023 notice](https://micro.rohm.com/en/financial/ir-news-releases/230718_news_en.pdf) on the 100 billion yen LP and 200 billion yen preferred commitments. - Rohm's [FY2025 financial report](https://fscdn.rohm.com/en/financial/financial-report/2603_financialresults_en.pdf): the loss, the impairment, the share count and the integration talks with Toshiba's and Mitsubishi Electric's chip units. - Blue Orca's [report page](https://www.blueorcacapital.com/blue-orca-is-long-rohm-6963-jp-chubu-electric-9502-jp-and-tre-9247-jp/) for the full presentation and disclaimers. - Toshiba's [FY2025 results](https://www.global.toshiba/content/dam/toshiba/ww/ir/corporate/finance/pdf/tpr2025q4e.pdf) for Kioxia gains and refinancing. ## What would prove it right or wrong? **Right:** Toshiba sets a relisting timetable, Rohm discloses a higher value for the stake, or Rohm's SiC and AI power sales lift earnings. **Wrong:** Kioxia keeps falling, Toshiba delays its listing, or Rohm's chip business needs more write-downs. *This is journalism and commentary, not investment advice. We hold no position unless stated.* ## Questions readers ask **What does Rohm (6963) do?** Rohm Co., Ltd. (Tokyo Stock Exchange: 6963) is a Kyoto-based maker of semiconductors, including analog chips and silicon carbide (SiC) power devices. Rohm reported net sales of 481.1 billion yen for the year ended March 31, 2026. **What is the market call on Rohm (6963)?** Blue Orca Capital says it is long Rohm because Rohm's stake in the 2023 Toshiba buyout is carried near cost but could return 8.5x to 17.5x its cost after tax. Blue Orca estimates 51% to 144% upside for Rohm in its sum-of-the-parts view. **How much did Rohm invest in the Toshiba buyout?** Rohm invested 100 billion yen as a limited partner in TB Investment Limited Partnership and underwrote 200 billion yen of non-voting preferred stock in TBJ Holdings in September 2023. Rohm funded the investment with debt from financial institutions, according to its September 22, 2023 notice. **Who is Blue Orca Capital and what is its track record?** Blue Orca Capital is a fund founded by Soren Aandahl in 2018 and best known for short reports. Blue Orca is not yet on our scoreboard, so it has no scored record, and it discloses that it is long Rohm and may trade at any time. **What is unusual about this Rohm call?** A fund known mainly for short selling pitched three Japanese longs at Sohn Tokyo on October 16, 2026: Rohm (6963), Chubu Electric Power (9502) and TRE Holdings (9247). Blue Orca says each holds a Toshiba stake that could be worth 80-96% of its market value. **Is Rohm (6963) a good bet right now?** We do not make recommendations. The case for Rohm is a private Toshiba stake that may be worth far more than its book value; the case against is a 158.4 billion yen net loss last fiscal year and no Toshiba listing before fiscal 2028 at the earliest, per Bloomberg. **Why did Rohm stock fall in October 2026?** Rohm closed at 5,096 yen on October 8, 2026 and 3,903 yen on October 20, about 23% lower. The drop came during a global AI and chip selloff that CNBC reported hit Japanese chip names such as Advantest and Renesas. **How does Kioxia affect the value of Rohm's Toshiba stake?** Toshiba still owns part of memory maker Kioxia, 12.84% as of September 7, 2026 per Nikkei, and Kioxia gains drove Toshiba's record FY2025 net income of 1,967.3 billion yen. Kioxia shares fell about 27% from October 8 to October 20, 2026, so the value of Rohm's indirect stake can swing sharply. **What happened to Denso's bid for Rohm?** Denso proposed to acquire Rohm shares in March 2026 and withdrew the proposal on April 28, 2026, after Rohm's board and special committee had not agreed to support it. Rohm said both companies will continue their chip partnership. **What would prove the Rohm call right or wrong?** The Rohm call looks right if Toshiba sets a relisting timetable, the stake is revalued higher, or Rohm's SiC and AI power sales lift earnings. It looks wrong if Kioxia keeps falling, Toshiba delays its listing, or Rohm needs more write-downs.
