Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

Effective October 29, 2020, the Board of Directors (the “Board”) of Twin Disc, Incorporated (the “Company”) restated the Bylaws of the Company (the “Bylaws”). The restated Bylaws contain the following changes:

●

Article I of the Bylaws was amended to indicate that the principal office of the Corporation in the State of Wisconsin shall be located in the City of Milwaukee, Milwaukee County. Previously, Article I of the Bylaws stated that the principal office of the Corporation in the State of Wisconsin shall be located in the City of Racine, Racine County.

●

Article II, Section (1) of the Bylaws was amended to indicate that the annual meeting of shareholders shall be held during the months of October or November in each year, and that if the date and time of the annual meeting of shareholders for any for any year shall not have been designated by the Board of Directors at least thirty (30) days prior to the first day of October of such year, then the annual meeting of shareholders shall be held at the registered office of the Corporation on the second Thursday of November in such year at 2 o’clock p.m., if not a legal holiday, but if a legal holiday, then on the next business day following. Previously, Article II, Section (1) of the Bylaws indicated that the annual meeting of shareholders would be held during the months of September or October in each year, and that if the date and time of the annual meeting of shareholders for any for any year was not designated by the Board of Directors at least thirty (30) days prior to the first day of September of such year, then the annual meeting of shareholders would be held at the registered office of the Corporation on the third Friday of October in such year at 2 o’clock p.m., if not a legal holiday, but if a legal holiday, then on the next business day following.

●

Article II, Section (2) of the Bylaws was amended to conform to the provision of the Wisconsin Business Corporation Law that allows special meetings of shareholders to be called at the request of shareholders owning at least ten percent (10%) of the outstanding shares of stock of the Corporation entitled to vote at the meeting. Previously, the Bylaws provided that special meetings of shareholders could be called by shareholders owning at least twenty-five percent (25%) of the outstanding shares of stock of the Corporation entitled to vote at the meeting.

●

The following sections of the Bylaws were amended to add provisions allowing shareholders and proxies of shareholders to participate in any annual meeting or special meeting of shareholders by means of remote communication:

Article II, Section (3) was amended to state that the Board of Directors may determine, in its sole discretion, that any annual meeting or special meeting of shareholders may be held solely by means of remote communication.

Article II, Section (4) was amended to state that the written notice of an annual meeting or special meeting of shareholders must state the means of remote communication, if any.

Article II, Section (6), was amended to add a provision for the accessibility of the shareholder list at any annual meeting or special meeting of shareholders that is held solely by means of remote communication.

Article II, Section (7) was amended to add provisions regarding providing notice of a new means of remote communication if an annual meeting or special meeting of shareholders is adjourned.

Article II, Section (12) was amended to state that a waiver of notice by a shareholder for an annual meeting or special meeting of shareholders need not specify the means of remote communication.

●

Article II, Section (14)(b) was amended to add provisions relating to the universal proxy rules in Rule 14a-19 under the Securities Exchange Act of 1934. The new provisions state that no shareholder may solicit proxies in support of nominees for the Board of Directors other than the Corporation’s nominees unless the shareholder complies with Rule 14a-19, and require that any such shareholder: (a) promptly notify the Corporation if it fails to comply with the requirements of Rule 14a-19(b) and Rule 14a-19(c); (b) notify the Corporation within two business days if it no longer intends to solicit proxies in support of director nominees other than the Corporation’s nominees; and (c) provide notice to the Corporation that it has met the requirements of Rule 14a-19(a)(3) at least five business days prior to the applicable meeting for the election of Directors.
