MR. PAUL RAYMOND FILES AN EARLY WARNING REPORT

Paul Raymond, president and chief executive officer 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. Raymond 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. Raymond and Pierre Turcotte, chairman of the board of directors 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. Mr. Raymond personally held 508,306 Class B shares (representing 6.94 per cent of the issued and outstanding Class B shares) and Fiducie Direxions (Direxions) owned 571,832 Class B shares (representing 7.80 per cent of the issued and outstanding Class B shares). This represented, in the aggregate 1,080,138 Class B shares beneficially owned and controlled by Mr. Raymond (representing 14.74 per cent of the issued and outstanding Class B shares).

Pursuant to the acquisition, Mr. Raymond 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 1,155,138 Class B shares, representing 15.77 per cent of the issued and outstanding Class B shares, of which 583,306 Class B shares are held personally and 571,832 Class B shares are owned by Direxions.

In addition, Mr. Raymond beneficially owns and controls: (a) 200,000 options to purchase Class B shares (all of which are vested); (b) 692,693 Class A shares; (c) 922,691 options to purchase Class A shares (all of which are vested); (d) 936,074 restricted share units (none of which are vested); (e) 936,074 performance share units (none of which are vested); and (f) 236,786 deferred share units, which settle in Class A shares (all of which are vested, but none of which can be settled within 60 days).

Assuming: (a) the exercise of the Class B options, 200,000 Class B shares would be issued and the total Class B ownership would increase to 1,355,138 Class B shares (representing 18.00 per cent of the issued and outstanding Class B shares); and (b) the exercise of the Class A options, 922,691 Class A shares would be issued and the total Class A ownership would increase to 1,615,384 Class A shares (representing 1.79 per cent of the issued and outstanding Class A Shares), and Mr. Raymond would control approximately 9.16 per cent of the total voting rights outstanding of Alithya (based on the number of Class B shares and Class A shares outstanding as of the date hereof and after giving effect to the issuance of the 200,000 Class B shares and the 922,691 Class A shares issuable under the Class B options and the Class A options). Of such ownership of 1,355,138 Class B shares and 1,615,384 Class A shares: (i) Mr. Raymond would beneficially own and control 783,306 Class B shares (representing 10.41 per cent of the issued and outstanding Class B shares) and 1,615,384 Class A shares (representing 1.79 per cent of the issued and outstanding Class A shares); and (ii) Mr. Raymond would control, and Direxions would own, 571,832 Class B shares (representing 7.60 per cent of the issued and outstanding Class B shares).

Assuming: (a) the exercise of the Class B options, 200,000 Class B shares would be issued and the total Class B ownership would increase to 1,355,138 Class B shares (representing 18.00 per cent of the issued and outstanding Class B shares); and (b) the exercise of the Class A options, and settlement in full of the RSUs, PSUs and DSUs, 3,031,625 Class A shares would be issued and the total Class A ownership would increase to 3,724,318 Class A shares (representing 4.03 per cent of the issued and outstanding Class A shares), and Mr. Raymond would control approximately 10.30 per cent of the total voting rights outstanding of Alithya (based on the number of Class B shares and Class A shares outstanding as of the date hereof and after giving effect to the issuance of the 200,000 Class B shares and the 922,691 Class A shares issuable under the Class B options and the Class A options, as well as the RSUs, the PSUs and the DSUs).
