Eisai stock was last at JPY 4,659.00 on the Tokyo Stock Exchange on October 5, 2026, down 0.87 percent from the previous close. The latest operating figures point in the opposite direction: fiscal first-quarter revenue rose 15.6 percent year over year to JPY 234.3 billion, while operating profit increased 19.2 percent to JPY 24.7 billion.

Leqembi drives the growth case

According to Yahoo Finance on October 3, 2026, quarterly profit attributable to owners of the parent reached JPY 18.2 billion, up 26.0 percent year over year. Leqembi revenue rose 26.7 percent to JPY 29.3 billion in the same fiscal quarter, keeping the Alzheimer medicine at the center of Eisai's growth profile.

The company also has a broader product catalyst. Eisai listed the September 16, 2026 approval of the subcutaneous Leqembi Pen in Japan and the September 28, 2026 U.S. approval of Welireg plus Lenvima for certain previously treated kidney cancer patients.

Consensus sits below the quote

Valuation remains a counterweight to the operating improvement. Marketscreener lists an Outperform consensus from 14 analysts, with an average target of JPY 4,575.00 versus a last close of JPY 4,658.00. The average target was 1.78 percent below that reference close, showing that the published consensus leaves limited upside at the cited level.

That tension is visible in the annual comparison. Fiscal year 2026 revenue reached JPY 825.378 billion, up 4.6 percent, but operating profit fell 18.8 percent to JPY 44.138 billion, according to note.com. Investors therefore have two measurable signals to weigh: faster first-quarter growth and the need to convert that growth into durable operating profitability.

Stock remains below yearly high
