Uber president and COO Andrew Macdonald buys $5.3 million of stock on the open market

Andrew Macdonald, president and chief operating officer of UBER, bought 70,000 shares of company stock on the open market on September 4, in two tranches: 54,325 shares at $75.6526 and 15,675 shares at $76.4425, for a combined outlay of roughly $5.3 million. The Form 4 disclosing the trades was filed September 8.

The transaction code is the detail that gives the purchase its meaning. These were coded as open-market discretionary buys, not option exercises, not vesting of restricted stock, and not a scheduled trading plan running in reverse. An executive committing $5.3 million of personal capital at market prices is a different signal from shares appearing in an account through compensation, and most insider-activity headlines do not make that distinction.

Macdonald was elevated to president and COO in 2026 and oversees the mobility and delivery businesses that generate the bulk of Uber's bookings. A purchase of this size from an operating executive rather than a board member or founder is comparatively uncommon, which is why it draws attention beyond the dollar figure itself.

Insider buying is a weak standalone signal and should not be read as a view on valuation. What makes it worth noting here is the size relative to a single officer's likely liquid net worth and the clean transaction code. What to watch: whether other members of the executive team file similar purchases in the coming weeks, and whether the buy lands before or after any change in the company's disclosed outlook.
