Executive summary
On 2026-05-06, Rep. Michael T. McCaul (R-TX) reported purchasing Coherent Corp. (NYSE: COHR) in the $15,001-$50,000 range (self), disclosed on 2026-06-10 (35-day lag). Coherent filed an 8-K on the same date reporting Q3 fiscal 2026 results, and earlier in 2026 filed an 8-K describing a $2 billion NVIDIA equity investment and strategic partnership. Insider Form 4 activity in the available window was net selling (including CFO sales on 2026-04-22 and 2026-05-12; director sales on 2026-05-11).
The analyzed COHR purchase occurred on the same calendar date as Coherent’s 2026-05-06 8-K (Items 2.02 and 7.01) furnishing a quarterly earnings press release and investor presentation. The member also purchased COHR again on 2026-05-07 and made 20 other trades within ±1 day of 2026-05-06 (user-provided same-day activity list), indicating that the COHR purchase was part of a larger multi-security trading batch during that period. For issuer context from primary filings available here: Coherent’s 2026-03-02 8-K disclosed an NVIDIA securities purchase and a $2 billion investment (Item 3.02) and the related press release described a multi-year strategic agreement, purchase commitment, and expansion of U.S.-based manufacturing. The Form 4 window provided (2026-04-06 to 2026-06-05) contained reported sales/withholding transactions by insiders and did not include open-market purchases in the extracted list. Several non-SEC primary-source research blocks (Congress.gov, Federal Register, USAspending, Regulations.gov, news) could not be executed in this environment; those gaps are documented above.
