Important Note About Tokenized Securities

Ciena Corporation (“Ciena”) objects to any and all notices or proposals by third parties to facilitate or commence trading on a “Tokenized Securities Venue” (TSV) pursuant to the U.S. Securities and Exchange Commission’s September 17, 2026 “Innovation Exemption” order of any of so-called “tokenized securities” where any securities of Ciena or its affiliates are the underlying asset.

Under the order, public companies have 30 days to object to a notice from a TSV that it intends to host trading of tokenized National Market System stock. We are not consenting to trading of any tokenized securities of Ciena or its affiliates and are not tokenizing or facilitating tokenization of any such securities.

We may withdraw this objection and consent to tokenization and trading of the securities of Ciena or its affiliates at a later date, but such withdrawal will only be effective when made in writing and signed by Ciena’s Chief Legal Officer or Deputy General Counsel.
