Mitsui Sumitomo Insurance Co., LTD, identified as a ten-percent owner of BERKLEY W R CORP (NASDAQ:WRB), reported a series of open-market purchases totaling $35.7 million. The transactions were carried out over two days, February 19 and February 20, 2026, and were executed under a Rule 10b5-1 purchase plan adopted on October 3, 2025.
Transaction details show three separate acquisitions. On February 19, the insurer completed two buys: 300,986 shares acquired at prices ranging from $70.0699 to $70.9988, and a second lot of 44,014 shares bought at prices between $71.0014 and $72.026. On February 20, Mitsui Sumitomo added 160,582 shares at prices ranging from $70.357 to $71.115.
Following these transactions, Mitsui Sumitomo Insurance Co., LTD directly holds 57,668,620 shares of W. R. Berkley Corporation common stock. At the time of reporting, Berkley shares were trading at $71.08 and the company carried a market capitalization of $26.81 billion. InvestingPro analysis cited in the filing indicates WRB appears undervalued at current levels, a factor the institutional investor’s purchases may reflect.
In parallel to the insider purchasing activity, W. R. Berkley disclosed its fourth-quarter 2025 financial results. The company reported revenue that exceeded analysts' expectations while earnings per share (EPS) came in line with consensus forecasts. The Board of Directors also declared a regular quarterly cash dividend of $0.09 per share, payable on March 4, 2026 to stockholders of record as of February 23, 2026.
These developments underline two observable themes for market participants: continued shareholder distributions in the form of a quarterly dividend, and institutional accumulation in the common stock. The purchases were executed pursuant to the plan adopted October 3, 2025, indicating pre-set trading arrangements rather than discretionary daily trading.
Details of the executed trades and the post-transaction holdings were disclosed in the filing reporting the 10b5-1 purchases. The filing specifies the price ranges and share counts for each of the three transactions while confirming the insurer’s direct holding after the transactions.
For investors tracking ownership trends and capital returns, the combination of an institutional insider increasing exposure and a company reporting revenue above expectations while maintaining EPS guidance and continuing dividend payments provides data points on both shareholder returns and management performance. The filing and corporate disclosures together outline the recent activity without offering forward-looking guidance beyond the announced dividend payment date and record date.
All transaction specifics, including share counts, price ranges, the Rule 10b5-1 plan adoption date, and the updated direct holding total are presented in the disclosure filed by the institutional holder.
