This prospectus supplement relates to the
resale by the selling stockholder referenced in this prospectus supplement of up to
2,108,993 shares of our common stock. This prospectus supplement covers the sale or other disposition by the selling stockholder of
up to the total number of shares of our common stock issued to the selling stockholder. The table below sets forth, to our
knowledge, information concerning the beneficial ownership of our common stock by the selling stockholder as of November 10, 2025.
The information in the table below with respect to the selling stockholder has been obtained from the selling stockholder. When we
refer to the “selling stockholder” in this prospectus supplement, we mean the selling stockholder listed in the table
below as offering shares, as well as its permitted assignees and successors-in-interest. Throughout this prospectus supplement, when
we refer to the shares of our common stock being registered on behalf of the selling stockholder, we are referring to the shares of
our common stock issued. The selling stockholder may sell all, some or none of the shares of our common stock subject to this
prospectus supplement. See “Plan of Distribution.”

The number of shares of our common stock beneficially
owned prior to the offering for the selling stockholder includes all common stock beneficially owned by the selling stockholder as of
November 10, 2025. The percentages of shares owned before the offering are based on 354,279,591 shares of our common stock outstanding
as of October 29, 2025.

Beneficial ownership is determined in accordance
with the rules of the SEC, which generally provide that a person has beneficial ownership of a security if such person possesses sole
or shared voting or investment power over that security or the right to acquire such power within 60 days. Unless otherwise indicated
below, to our knowledge, the selling stockholder named in the table has sole voting and investment power with respect to the shares of
our common stock beneficially owned by it, except to the extent authority is shared by spouses under applicable law. The inclusion of
any shares in this table does not constitute an admission of beneficial ownership for the selling stockholder named below.
