The purchase of 50,000 shares represents a total transaction value of ~$1.1 million based on the September 14, 2026 transaction date.
The acquisition size was equal to 0.35% of the total equity stake held by the Executive Chairman before the filing.

Ernest S. Rady, the founder and Executive Chairman of American Assets Trust, Inc. (NYSE:AAT), purchased 50,000 shares of common stock at $21.65 per share on Sept. 14, 2026. SEC Form 4 filing.
Transaction value based on SEC Form 4 weighted average purchase price ($21.65); post-transaction value based on Sept. 14, 2026 market close ($21.64).
American Assets Trust is a diversified real estate investment trust with a market capitalization of $1.30 billion, leveraging over 50 years of operational expertise in premium property acquisition and management. The company maintains a fully integrated management structure with 232 employees, generating $439.70 million in trailing twelve-month (TTM) revenue while demonstrating operational profitability with $20.70 million in TTM net income. AAT's competitive positioning centers on its focus on high-barrier-to-entry markets and its internally managed operational model, which provides enhanced control over asset quality and tenant relationships.
Rady founded American Assets Trust in 1967 and has led the business ever since. He knows the company and its market inside and out.
His purchase is bullish, especially in light of the fact he purchased nearly 600,000 shares already a few weeks ago.
We like to see insider buying like this as a signal to investigate a stock more closely.
Why? Consider the dynamics of insider buying and selling. There are many reasons an insider may sell shares, some of which have no bearing on their belief in the stock's direction, such as having to pay a large personal expense or diversifying their holdings.
Then consider that there is only one reason an insider buys shares: they believe the stock price will rise.
By that rule of thumb alone, Rady's purchase of more than $1 million worth of American Assets Trust shares is bullish. That signal is further bolstered by studies showing that, more often than not, an insider purchase predicts a higher share price 30 days later.
AAT management sees strength in its business, with strong multifamily rents, better-than-expected rent payments from delinquent business leases, and strong tourism at its Hawaii hotel properties. Rady's insider buying rounds a bullish tale for the REIT.
