Caterpillar disclosed a large insider sale on May 6, 2026, when Andrew R. J. Bonfield, listed as CFO Emeritus, sold 15,674 shares at $918.71 per share for about $14.40 million. By dollar value, this is one of the biggest insider transactions reported at the company in the past month and stands out because it was an open-market sale rather than a private transfer. Bonfield’s “CFO Emeritus” title indicates he is a former chief financial officer who may still have a close view of the business and significant equity holdings from prior compensation. While sales can happen for many personal reasons (such as taxes, diversification, or scheduled selling plans), investors often watch large sales by finance leaders because they have historically been deeply involved in budgeting, cash flow, and capital allocation decisions. This trade also occurred alongside multiple other executive sales over a short window. On the same day, Bob De Lange sold about $13.35 million and Anthony D. Fassino sold about $8.15 million, following sales by Rodney Michael Shurman ($4.65 million on May 5) and Jason Kaiser ($4.98 million on May 4). A cluster of sizable sales can be notable as a pattern of insiders reducing exposure at similar price levels, even though it does not, by itself, explain the motivation behind each transaction.
