A newly filed Periodic Transaction Report shows Hon. Richard Dean Dr McCormick, a member of the U.S. House of Representatives, purchased shares of Berkshire Hathaway Inc. New Common Stock (BRK.B) on July 30, 2026. The disclosure, required under the STOCK Act, lists the transaction value in the $1,001 to $15,000 range and notes the purchase was made personally by the member, held through a Growth Partners Roth IRA.
The filing is straightforward in its details: a single purchase, a single asset, and a disclosed range rather than an exact dollar figure, which is standard practice for these reports. Our internal classification tags this as a ‘congress buy’ signal, meaning it reflects an acquisition of shares rather than a sale or exchange.
A Notable Timing Overlap
What makes this filing stand out is its proximity to another BRK.B transaction reported separately. Company insider Michael J. O’Sullivan purchased shares of the same stock on August 12, 2026, in an amount of $22,979, according to a separate insider-trading disclosure. That purchase falls within 30 days of McCormick’s reported transaction date, placing both buys in a similar window of time.
Whoisbuyingnow.com tracks these kinds of overlaps because they can indicate broader interest in a particular stock from multiple types of market participants: elected officials required to disclose personal trades, and corporate insiders required to disclose their own transactions under separate SEC rules. Seeing both a congressional purchase and an insider purchase of the same ticker within a short window is the kind of pattern our site is built to surface, even though the two disclosures come from entirely different reporting regimes and legal requirements.
It is worth noting that STOCK Act disclosures like this one are a legal obligation for members of Congress, not an indication of any wrongdoing. Lawmakers are required to report trades made by themselves, their spouses, or dependent children within 30 to 45 days of the transaction. The Growth Partners Roth IRA structure listed here is simply the account vehicle through which the purchase was executed.
No additional details about the rationale behind the purchase, or about O’Sullivan’s insider transaction, were included in the respective filings. As with all disclosures of this kind, the public record shows only the fact of the transaction, the approximate dollar range, and the date, leaving broader context outside the scope of what is legally required to be reported.
Whoisbuyingnow.com will continue monitoring subsequent filings tied to BRK.B and to Rep. McCormick’s disclosed holdings for any further overlaps worth noting.
