Toshiba's leftover 11.8% stake in Kioxia, a holding left over from a 2018 sale to Bain, is now estimated to be worth about ¥2.5 trillion, more than the ¥2.35 trillion paid to take all of Toshiba private in 2023.
That gap sits at the center of a wider argument: that an operating recovery at Toshiba and surging AI-linked demand mean the Toshiba stakes held by Rohm, Chubu Electric Power, and TRE Holdings could each be worth 80% to 96% of those companies' current market capitalizations. Blue Orca Capital, which discloses long positions in Rohm, Chubu Electric Power, and TRE Holdings securities, estimates the original buyout equity could generate a 12x to 25x gross return.

Position Disclosure: Blue Orca states it is long Rohm, Chubu Electric Power, and TRE Holdings securities.
Thesis
Blue Orca Capital, which is long all three stocks, argues that Rohm, Chubu Electric Power, and TRE Holdings are undervalued because their financing stakes in the 2023 Toshiba take-private are worth far more than the market currently credits.
- Leveraged Buyout Setup: The roughly ¥2,350 billion Toshiba transaction was funded with only an estimated ¥716 billion of equity, mostly from Japanese corporate investors; Blue Orca estimates the deal could generate a 12x to 25x gross multiple on that equity.
- Kioxia Sales Erase Debt: Blue Orca estimates Toshiba has sold approximately ¥2,200 billion of Kioxia stock, which it says would more than repay the buyout's debt, mezzanine, and preferred financing, leaving Toshiba with significant net cash.
- Hidden Stakes: At the midpoint of Blue Orca's equity-value estimate, the gross value of the Toshiba stakes held by Rohm, Chubu Electric Power, and TRE Holdings could equal 80% to 96% of each company's current market capitalization.
- Operating Inflection: A chart sourced to Toshiba's own IR materials shows quarterly revenue growth swinging from roughly -8% to about 27% year-over-year, while EBITDA margin recovered from near 0% to 14%-16% in the quarters following the buyout.
- AI Demand Comparables: Toshiba's energy, semiconductor, and storage units sell transformers, SiC/GaN power chips, and nearline HDDs to hyperscalers; comparables GE Vernova (up 7x), Seagate (up 9x), the Japan Semiconductor ETF (up 2x), and Hitachi (up 2.8x) have all risen since the buyout closed.
- FY3/28 Forecast: Blue Orca's model projects Toshiba EBITDA rising to ¥780.9 billion at a 16.0% margin by FY3/28, from ¥481.8 billion and a 13.0% margin in FY3/26.
- Kioxia ADR Listing: The report cites unspecified media reports that Kioxia is considering a U.S. ADR listing, which Blue Orca says could improve its valuation and liquidity.
Catalysts
- Forward operating results: Toshiba's FY3/27 and FY3/28 results, including continued revenue growth and margin expansion toward Blue Orca's ¥617.9 billion and ¥780.9 billion EBITDA forecasts, would support the valuation case.
- Kioxia stake monetization or uplift: Any further sale or price appreciation of Toshiba's remaining 11.8% Kioxia stake, currently estimated at ¥2.5 trillion, would add to or realize that value.
- Potential U.S. ADR listing: A potential Kioxia U.S. ADR listing, flagged in media reports cited by Blue Orca, could improve the stock's liquidity and valuation.
- Holdco re-rating: A market re-rating of Rohm, Chubu Electric Power, or TRE Holdings if investors begin pricing in the 80%-96% Toshiba stake value Blue Orca estimates for each company.
Company Response
The report does not describe a request for comment to Toshiba, Japan Industrial Partners, Kioxia, Rohm, Chubu Electric Power, TRE Holdings, or Bain, and no company response is reported.
Notable Details
- Kioxia shares have risen approximately 27x from their IPO price, even after falling from roughly ¥35,000-37,000 in May-June 2026 to about ¥13,000-18,000 by August-September 2026, per Bloomberg LP data cited in the report.
- Toshiba was taken private in 2023 at a price similar to its pre-scandal 2015 valuation, following eight years of underperformance tied to its earlier accounting and governance scandals.
- Blue Orca values Kioxia at just 3.4x projected FY3/27 earnings and 2.7x projected FY3/28 earnings.
- Toshiba's Devices & Technology segment, which includes power semiconductors and analog ICs, is modeled to see net sales rise from ¥900 billion in FY3/25 to ¥1,527.4 billion in FY3/28.
"Despite selling a majority stake to Bain in 2018, Toshiba retains an 11.8% stake in Kioxia worth ~¥2,500B, 1.1x original total Toshiba buyout value of ~¥2,350B and ~3.5x ~¥716B equity check."
This passage from page 7 of the report distills Blue Orca's core argument: that Toshiba's retained Kioxia stake alone may exceed the value of the entire 2023 buyout.
FAQs
What is 6963 JP (Rohm Co. Ltd.) and why is Blue Orca highlighting it?
Rohm Co. Ltd. is one of three publicly traded Japanese companies that financed the 2023 Toshiba take-private as a limited partner. Blue Orca argues Rohm's Toshiba investment could be worth 80% to 96% of its current market capitalization at the midpoint of the firm's equity-value estimate, a claim Blue Orca makes while holding a long position in Rohm shares.
What is Toshiba's connection to Rohm, Chubu Electric Power, and TRE Holdings Corporation?
Rohm, Chubu Electric Power, and TRE Holdings Corporation are described as public-company investors in the consortium, led by Japan Industrial Partners, that took Toshiba private in 2023. The buyout had a total capitalization of roughly ¥2,350 billion but was financed with only an estimated ¥716 billion of equity, largely from Japanese corporate backers including these three companies.
What is Blue Orca Capital's position in Rohm, Chubu Electric Power, and TRE Holdings?
Blue Orca Capital states it holds long positions in the securities of Rohm, Chubu Electric Power, and TRE Holdings. The firm presented its thesis at the Sohn Tokyo conference on October 16, 2026, arguing the three companies' Toshiba stakes are undervalued relative to their market caps.
What is Kioxia and why does it matter to Toshiba's valuation?
Kioxia is a memory-chip maker in which Toshiba sold a majority stake to Bain in 2018 while retaining an 11.8% ownership position. The report estimates that retained stake is now worth about ¥2.5 trillion, more than the ¥2.35 trillion total value of the 2023 Toshiba buyout, and notes Kioxia shares have risen roughly 27x from their IPO level, though they pulled back from a mid-2026 peak.
How much could the Toshiba buyout equity be worth, according to the report?
Blue Orca estimates the Toshiba take-private could generate a 12x to 25x gross multiple on the approximately ¥716 billion of equity used to fund the deal. The estimate rests on Toshiba's projected FY3/28 EBITDA of ¥780.9 billion, the estimated value of its retained Kioxia stake, and the performance of comparable companies such as Hitachi, GE Vernova, and Seagate since the buyout closed.
Has Toshiba's financial performance actually improved since the 2023 buyout?
Per Toshiba's own IR materials cited in the report, quarterly year-over-year revenue growth moved from roughly -8% in FY3/24 to about 27% by FY3/26 Q4-FY3/27 Q1, while EBITDA margin recovered from near 0% to roughly 14%-16% over the same stretch. Blue Orca's model extends that trend, forecasting EBITDA of ¥780.9 billion and a 16.0% margin by FY3/28.
Did Toshiba, Rohm, Chubu Electric Power, or TRE Holdings respond to the report?
The report does not indicate that any of these companies, or Japan Industrial Partners, Kioxia, or Bain, were asked for comment, and no response from any of them is documented.
What could prove or disprove Blue Orca's thesis on these stocks?
Key tests include whether Toshiba's revenue and margins continue tracking toward the FY3/27-FY3/28 forecasts, whether Toshiba further monetizes its Kioxia stake, and whether a reported potential U.S. ADR listing for Kioxia materializes. If the market does not come to price the implied Toshiba stake value into Rohm, Chubu Electric Power, or TRE Holdings' share prices, Blue Orca's central valuation gap would remain unrealized.
