Wyo. Stat. § 17-16-141 (2026)

(a) Notice under this act shall be in writing unless oral
notice is reasonable under the circumstances. Notice by
electronic transmission is written notice.

     (b) Notice may be communicated in person; by telephone,
telegraph, teletype, or other form of wire or wireless
communication; or by mail or private carrier. If these forms of
personal notice are impracticable, notice may be communicated by
a newspaper of general circulation in the area where published;
or by radio, television, or other form of public broadcast
communication.

     (c) Written notice by a domestic or foreign corporation to
its shareholder, if in a comprehensible form, is effective:

          (i) Upon deposit in the United States mail, if mailed
postpaid and correctly addressed to the shareholder's address
shown in the corporation's current record of shareholders;

          (ii) When an electronic transmission has been made to
a data address provided by the shareholder; or

          (iii) When electronically transmitted to the
shareholder in a manner otherwise authorized by the shareholder.

     (d) Written notice to a domestic or foreign corporation
authorized to transact business in this state may be addressed
to its registered agent at its registered office or to the
corporation or its secretary at its principal office shown in
its most recent annual report or, in the case of a foreign
corporation that has not yet delivered an annual report, in its
application for a certificate of authority.

     (e) Except as provided in subsection (c) of this section,
written notice, if in a comprehensible form, is effective at the
earliest of the following:

         (i)     When received;

          (ii) Five (5) days after its deposit in the United
States mail, as evidenced by the postmark, if mailed postpaid
and correctly addressed; or

          (iii) On the date shown on the return receipt, if
sent by registered or certified mail, or comparable private
carrier, return receipt requested, and the receipt is signed,
either manually or in facsimile, by or on behalf of the
addressee.

     (f) Oral notice is effective when communicated if
communicated in a comprehensible manner.

     (g) If this act prescribes notice requirements for
particular circumstances, those requirements govern. If
articles of incorporation or bylaws prescribe notice
requirements, not inconsistent with this section or other
provisions of this act, those requirements govern.
