Tsumura (JP3535800001) completed its Yomeishu acquisition on September 1, 2026, according to Kabutec.jp. The transaction adds a new corporate development to a year already defined by earnings and portfolio changes.

Three milestones since May

On May 13, 2026, Tsumura reported fiscal 2026 revenue of JPY 192.62 billion, down 6.40 percent from the prior year. On August 6, 2026, its first-quarter revenue for fiscal 2027 reached JPY 49.70 billion, up 15.30 percent year over year, according to Tsumura and Co. The September 1 acquisition completion was the latest of the three events, as reported by Kabutec.jp.

What does the deal mean for earnings?

The immediate benchmark remains Tsumura's operating performance. First-quarter net income was JPY 6.46 billion, up 47.80 percent year over year, while the full-year fiscal 2027 outlook calls for revenue of JPY 213.60 billion and net income of JPY 26.20 billion, according to Kabutec.jp. That combination makes integration execution and the next earnings update more important than the acquisition announcement alone.

Two reporting dates are scheduled

Tsumura's next scheduled reporting date is November 9, 2026, for fiscal 2027 second-quarter results, followed by February 9, 2027, for third-quarter results, according to the company's investor-relations page. Both dates give investors a defined timetable for measuring the business after the Yomeishu transaction.

Market value sets the frame

Tsumura had a market capitalization of JPY 286.5 billion as of October 19, 2026. The company is listed on the Tokyo Stock Exchange under ticker 4540, and its core business remains centered on pharmaceutical products and traditional Japanese medicine.
