アローストリート・キャピタル・リミテッド・パートナーシップ Cuts Stake in レーザーテック (6920) to 4.19% | Large Shareholding Report

A large shareholding report (EDINET filing) shows that Arrow Street Capital Limited Partnership has reduced its stake in Laser Tek (6920) to 4.19%. The reduction comes from an activist investment fund based in the United States. Laser Tek manufactures semiconductor production equipment, developing and selling precision devices such as lithography systems and laser processing machines. The 4.19% stake represents a major institutional investor position in the company's market capitalization. This follows the previous disclosure, where the holding stood at 5.22%, marking a 1.03 percentage point decline.

Staged divestment since November last year

Arrow Street Capital first disclosed its Laser Tek position on November 6, 2025, reporting a 5.22% stake. This current filing marks the second disclosure, with the holding reduced by 1.03 percentage points over approximately nine months. The divestment occurred in stages rather than through a single transaction. The estimated sale amount totals ¥34.58 billion, reflecting Laser Tek's share price movements during this period.

Position within the fund's broader portfolio

The fund holds stakes exceeding 5% in eight companies across diverse sectors. Its largest holding is AI Mecha Tech (machinery, 7.86%), followed by Tokyo Communications Group (services, 6.98%), Coconala (information and communications, 5.37%), China Rare Earth Holdings (chemicals, 5.33%), and Kyoei Tanker (shipping, 5.14%). At 4.19%, Laser Tek has dropped below the fund's core holdings threshold. The investor spreads capital across machinery, chemicals, shipping, and information technology without concentrating in any single sector.

Standing in Laser Tek's shareholder composition

Comparing Arrow Street Capital to other institutional investors who filed large shareholding reports for Laser Tek illustrates the scale of its position. The second-largest disclosed holding belongs to Mitsui Sumitomo Trust Asset Management at 2.24%, followed by BlackRock Japan at 1.98%. Nomura Securities holds 0.4% and Nomura Asset Management holds 0.03%. Even after this reduction, Arrow Street Capital remains among Laser Tek's largest institutional investors.

Valuation metrics and market positioning

At the disclosure date, Laser Tek traded at a PER of 73.7x and a PBR of 14.89x. The elevated PER indicates the stock is valued highly relative to earnings, while the high PBR reflects substantial premium pricing against book value per share. The stock's position within its 52-week range stands at 54%, placing it neither near lows nor highs over the past year.

*Speculation: The fund may be reassessing its activist engagement strategy or rebalancing capital allocation to prioritize positions in other portfolio companies.
