Despite appearances, Japan's Toto isn't just the name behind heated bidets and "Washlet" throne technology anymore. According to a report from Financial Times, the UK-based activist investor Palliser Capital just surfaced in its shareholder registry with a letter to the board saying that the company's advanced ceramics business is being wildly undervalued by the market. In other words, a loo maker might now be sitting at the crossroads of AI infrastructure and semiconductor supply chains.
Now, Palliser is explicitly calling Toto "the most undervalued and overlooked AI memory beneficiary" in its letter — which is activist language, not impartial research. Still, it's grounded in a real here-and-now connection between AI investment trends and semiconductor supply chains.
Palliser is pushing Toto to do a better job explaining this segment to the market, streamline capital allocation, and use its ~¥76 billion ($496 million US) net cash more strategically, including a potential expansion of its ceramics business ahead of the competition. Goldman Sachs and other research desks have talked up the profit potential tied to these components, even lifting ratings in the past year based on the assumption of a rebounding NAND market.
Toto's shares have already seen strong moves, with gains of nearly 40% to date this year tied to both analyst coverage and activist newsflow. In short, traders aren't just laughing at the idea of bidding up a bidet maker because "AI." Instead, they're following revenue, profit, and end-market demand signals that, as strange as it sounds, track with beefed-up capital spend on memory fabs to attempt to meet the insane demand we're seeing now.
That said, claims of a five-year technological moat largely come from Palliser's pitch to shareholders. It's a bullish thesis, not an independent guarantee, and Palliser has a vested interest in that claim being accurate. Also, while electrostatic chucks absolutely play a role in advanced, low-temperature etch processes, the idea that this will drive a measurable growth surge is arguably still more "industry narrative" than something that's necessarily clear when looking at public fab spending data. All of the major memory manufacturers have been highly reluctant to commit to large production expansions, citing an unwillingness to be stuck with a glut of stock if the market turns abruptly (as it may well do, given well-founded fears of an AI 'bubble'.)
Toto's journey from Washlet ad campaigns to semiconductor materials speaks to the idea that AI is reshaping how investors think about supply chains. It's not just Nvidia and AMD; it's the materials and components that enable chip production. In Japan, you're seeing this theme elsewhere, too; other traditional manufacturers, from seasoning companies like Ajinomoto (making materials for chip substrates) to cosmetics companies producing wafer cleaning agents, are being reevaluated through the AI lens. Let's hope these companies don't forget their roots lest the consequences of an AI market crash take out our toilet vendors, too.
