Filed by Banco Bilbao Vizcaya Argentaria, S.A.

Pursuant to Rule 425 under the Securities Act of 1933

Subject Company: Banco de Sabadell, S.A.

Commission File No.: 001-10110

Dear Shareholder:

The Extraordinary Shareholders’ Meeting held on Friday in Bilbao approved the capital increase required to extend our offer to Banco Sabadell shareholders. With a quorum at record levels at 70.75 percent, and a favorable vote of 96 percent, we have achieved a significant milestone in advancing the most attractive banking project in Europe. I want to thank you for your trust and support, both personally and on behalf of BBVA.

This operation is a clear commitment to Spain and its SMEs. The integration with Banco Sabadell will strengthen our position in a key market, resulting in a stronger, more competitive, and profitable bank. The larger scale and the combination of two such complementary businesses will allow us to generate more value for all our stakeholders.

BBVA shareholders will see improvements in earnings per share and in tangible book value per share, as well as high investment returns with limited capital consumption. Banco Sabadell shareholders will receive a very attractive premium and 16% ownership in the resulting entity. Additionally, all will benefit from BBVA’s shareholder remuneration policy, which involves distributing between 40% and 50% of profit, and from our intention to distribute any excess capital above 12%. Furthermore, customers will have access to a better product offering and employees to more professional growth opportunities.

For all these reasons, we have full confidence in the success of this operation, which will allow us to amplify our positive impact while contributing to our purpose of bringing the age of opportunity to everyone.

Kind regards,

/s/ Carlos Torres Vila

Carlos Torres Vila, Chair
