Dropbox Co-CEO Filing Corrects Unauthorized Broker Transactions in Trust Account

According to the amendment, on November 2, 2026, a broker inadvertently executed unauthorized sales of 383,800 shares of Class A Common Stock held by the Andrew Houston Revocable Trust during a restricted period defined under a Rule 10b5-1 trading plan entered by the trust. The original Form 4, filed on November 4, 2026, reported those sales. The amendment was filed on November 9, 2026, to correct the record after the broker unwound the transactions and restored the shares to the trust's account.

Andrew Houston, who is identified in the filing as Co-CEO, director, and a 10% owner, holds the corrected beneficial interest indirectly through the Andrew Houston Revocable Trust u/a/d 9/7/2011, for which he serves as trustee. The amendment records a transaction code of "S" with an amount of 0 shares disposed at a price of $0, reflecting that the originally reported sales are treated as nullified. Following this corrected transaction, the filing states that 383,800 shares of Class A Common Stock remain indirectly beneficially owned by the reporting person through the trust.

The amendment was signed by Cara Angelmar as attorney-in-fact on November 9, 2026. The filing contains no record of any new or additional transactions beyond the correction described above, and no derivative securities are reported in Table II.
