株式会社ヒロコーポレーション Cuts Stake in セリア (2782) to 12.62% | Large Shareholding Report

A large shareholding report (EDINET filing) reveals that Hiro Corporation reduced its stake in Seria (2782) to 12.62%. The filer is an asset management company established under an individual investor's name, while Seria operates the 100-yen shop chain of the same name and retails household goods, stationery, and kitchenware. The 12.62% holding represents a controlling stake comparable to a major shareholder of significant scale. From the previous disclosure, the shareholding ratio fell by 1.31 points, with an estimated sale value of ¥3.12 billion.

Phased Reduction of Over 20 Percentage Points Within One Year

Hiro Corporation's investment in Seria dates to July 22, 2025, when the initial disclosure showed a 33.14% holding. Approximately one year later, this has declined to 12.62%. During the intervening period, the company filed six large shareholding reports, documenting a gradual reduction in equity. The drop from 33.14% to 12.62% represents a decrease of 20.52 percentage points. Through five change reports submitted over twelve months, the holding has been cut to less than one-third of its initial size.

Shifting Position in Seria's Shareholder Base

Among publicly disclosed large shareholders in Seria, Sprouts Grove Investment Management Limited holds 4.78%. Hiro Corporation's 12.62% substantially exceeds this figure and remains the subject of mandatory disclosure requirements. However, at the 33.14% level recorded at the outset, the company likely held the position of lead shareholder in Seria. The series of sales has materially altered its relative standing within the company's shareholder structure.

Stock Price and Market Valuation at Transaction Time

At the disclosure date of July 24, 2026, Seria's share price stood at ¥3,805. At this valuation, the PER (price-to-earnings ratio) was 47.1x and the PBR (price-to-book ratio) was 2.72x. A PER exceeding 40x indicates that the market has priced in elevated growth expectations, while a PBR above 2.0x reflects premium valuation relative to net assets. The stock was positioned at approximately 60% within its 52-week range, suggesting the transaction occurred after a material advance from the year's lows.

*Speculation: Hiro Corporation's decision to execute a large-scale reduction of its stake from one-third to one-fifth over the span of a year may reflect either a profit-taking opportunity as Seria's share price reached elevated levels, or alternatively, a response to capital requirements.
