Nu Holdings Announces US$1.0 Billion Share Repurchase Program

São Paulo, June 4, 2026 – Announced today that its board of directors has approved a share repurchase program under which Nu, or any of its affiliates, as determined by management, may repurchase up to US$1,000,000,000.00 of its outstanding Class A ordinary shares in the open market, based on prevailing market prices, or in privately negotiated transactions, over a 12-month period beginning on June 4, 2026 and ending on June 3, 2027 (the “Repurchase Period”), unless earlier terminated, suspended or completed.

Under the share repurchase program, repurchases may be made from time-to-time in the open market, in derivative transactions and pursuant to negotiated purchases in compliance with Rule 10b-18 and/or Rule 10b5-1, promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended. The actual timing, number and value of shares repurchased under the repurchase program will depend on several factors, including constraints specified in the Rule 10b-18, price, general business and market conditions, and alternative investment opportunities.

Nu’s board of directors will review the repurchase program periodically during the Repurchase Period and may authorize adjustments to its terms and size or suspend or discontinue the repurchase program, including authorizing any extension of the Repurchase Period beyond June 3, 2027. The repurchase program does not obligate Nu to acquire any specific number of shares in any period, and may be expanded, extended, modified or discontinued at any time.

Nu expects to utilize its cash balances derived from retained and future earnings to fund repurchases made under the repurchase program. Nu anticipates that shares acquired through this program will be retained in treasury or subsequently canceled, pursuant to governing legal requirements.
