Pierre Turcotte, chairman of the board of directors of Alithya Group Inc., filed today an early warning report with respect to his holding of Class B multiple voting shares of Alithya, as required by applicable securities laws.

On Sept. 2, 2026, Mr. Turcotte acquired 75,000 Class B shares from Ghyslain Rivard, a director of Alithya, for an aggregate purchase price of $84,165.75. The acquisition was made in the context of a sale, for estate planning purposes, of an aggregate of 150,000 Class B shares to Mr. Turcotte and Paul Raymond, president and chief executive officer of Alithya, in equal parts. The price per Class B share was $1.12221, being the volume weighted average trading price of the Class A subordinate voting shares of Alithya on the Toronto Stock Exchange for the 20 trading days immediately preceding the acquisition.

Before the acquisition, a total of 7,326,880 Class B shares and 89,438,673 Class A shares were issued and outstanding and Mr. Turcotte personally held 365,884 Class B shares (representing 4.99 per cent of the issued and outstanding Class B shares) and 9387-1010 Quebec Inc., a company controlled by Mr. Turcotte (QuebecCo), owned 1,468,858 Class B shares (representing 20.05 per cent of the issued and outstanding Class B shares). This represented, in the aggregate, 1,834,742 Class B shares beneficially owned and controlled by Mr. Turcotte (representing 25.04 per cent of the issued and outstanding Class B shares).

Pursuant to the acquisition, Mr. Turcotte acquired 75,000 Class B shares, representing 1.02 per cent of the issued and outstanding Class B shares, resulting in a total Class B ownership of 1,909,742 Class B shares (representing 26.06 per cent of the issued and outstanding Class B shares).
