Sumitomo Chemical Stock Slides on Short-Seller Report Targeting Subsidiary
Shares of Sumitomo Chemical (TYO:4005) fell sharply in Tuesday trading, pressured by a high-profile short-seller report targeting its subsidiary and general investor caution ahead of its upcoming earnings release.
Gotham City Alleges Misstatement
The primary catalyst for the decline was a report published on August 3 by Gotham City Research, according to Investing.com. The report accused Sumitomo Pharma, a listed subsidiary in which Sumitomo Chemical holds a controlling stake, of misstating its fiscal 2025 financial statements by as much as ¥165 billion (approximately $1.05 billion).
Gotham City's allegations center on the manipulation of receivables to artificially inflate profits. The short-seller specifically highlighted a ¥48 billion dividend from a Swiss subsidiary announced in March 2026, just weeks before the end of the company's fiscal year, as a point of concern.

In response to the news, Sumitomo Chemical's stock dropped 3.6% to close at ¥494.1 on Tuesday. The shares touched an intraday low of ¥491.3, a significant drop from the previous session's closing price of ¥512.6.
The decline was exacerbated by weakness in the broader Japanese equity market. The Nikkei 225 index fell 0.6% on Tuesday, following a 1% drop on Monday, reflecting a cautious sentiment among investors.
