Advanced AI Chip Probing Partnership Could Be A Game Changer For Tokyo Seimitsu (TSE:7729)

• In December 2025, Advantest Corporation and Tokyo Seimitsu Co., Ltd. announced a plan to co-develop a die-level prober for testing advanced AI and high-performance computing devices, addressing challenges such as heat management in 2.5D/3D packaging.
• This collaboration signals a tighter integration across the semiconductor test value chain, potentially enhancing both companies’ roles in supplying tools for increasingly complex chip architectures.
• Next, we’ll consider how this co-development of advanced AI and HPC probing technology shapes Tokyo Seimitsu’s broader investment narrative.

What Is Tokyo Seimitsu's Investment Narrative?

To own Tokyo Seimitsu, you really have to believe in its role as an enabling supplier to steadily growing semiconductor test and metrology demand, rather than a hyper-growth AI pure play. Short term, the key catalysts still look like order trends in the SPE segment, execution against its FY2026/3 guidance after the recent downward EPS revision, and how far management leans into shareholder returns following the dividend reset. The new co-development with Advantest adds an interesting twist: it could deepen Tokyo Seimitsu’s relevance in AI and HPC testing, but given the early stage and lack of quantified targets, the earnings impact is unlikely to be immediate. For now, it subtly shifts the story toward higher-spec tools, while the bigger risks remain margin pressure, quality-related cost provisions and recent volatility in the share price.

However, one issue in particular could challenge the appeal of today’s valuation and dividend profile. Tokyo Seimitsu's share price has been on the slide but might be up to 7% below fair value. Find out if it's a bargain.
