Insights

Cross-border equities and disclosure analyst

Telefónica is moving to delist from NYSE and end SEC reporting within about 90 days, shifting U.S. investors to non-SEC disclosure.

Telefónica and two wholly owned subsidiaries are filing Forms 15F to voluntarily deregister and suspend their reporting obligations under the U.S. Securities Exchange Act of 1934. This follows an earlier announcement of plans to delist American Depositary Shares and certain debt securities from the New York Stock Exchange, indicating a coordinated withdrawal from U.S. listing and reporting frameworks.

The filing states that deregistration and termination of reporting obligations are expected to become effective 90 days after the Forms 15F are filed, unless the SEC objects. Once effective, investors will no longer receive SEC-format disclosures such as 20-F and 6-K, although the company will continue to prepare consolidated financial statements in accordance with IFRS, which may still be available via its home-market channels.

For investors who hold Telefónica securities via U.S. markets, this change primarily affects trading venue, regulatory oversight, and disclosure format rather than the underlying business operations. Future company communications and IFRS financial statements will be the key sources for ongoing information after deregistration is effective.
