MAINSTREET ANNOUNCES ENTERING INTO OF AUTOMATIC SHARE PURCHASE PLAN

In connection with Mainstreet Equity Corp.'s previously announced normal course issuer bid (NCIB) to purchase up to 475,359 of its outstanding common shares during the 12-month period beginning June 3, 2025, and ending June 2, 2026, it has entered into a automatic share purchase plan (ASPP) with its designated broker. The ASPP is intended to allow for the purchase of shares under the NCIB during predetermined times when Mainstreet would ordinarily not be permitted to purchase shares due to customary blackout periods.

The company has entered into the ASPP with its designated broker under which it has authorized the designated broker to make purchases under the NCIB in accordance with the terms of the ASPP. Such purchases will be determined by the designated broker at its sole discretion based on certain parameters as to price and number of shares set by Mainstreet in accordance with the rules of the Toronto Stock Exchange ("TSX"), applicable securities laws and the terms of the ASPP.

The ASPP constitutes an "automatic plan" for the purposes of applicable securities laws and has been pre-cleared by the TSX. The ASPP will terminate when the NCIB expires, unless terminated earlier in accordance with the terms of the ASPP. Outside of pre-determined blackout periods, shares may be purchased under the NCIB based on management's discretion, in compliance with TSX rules and applicable securities laws. All purchases made under the ASPP will be included in computing the number of shares purchased under the NCIB.
