Exhibit 99.1

ANNUAL AND SPECIAL MEETING OF SHAREHOLDERS OF LEDDARTECH HOLDINGS INC.
NOTICE-AND-ACCESS NOTIFICATION TO SHAREHOLDERS

As permitted by Canadian securities regulators, LeddarTech Holdings Inc. (the “Company”) is using notice-and-access to deliver (a) its management information circular in respect of its annual and special meeting of shareholders (the “Information Circular”), and (b) its audited consolidated financial statements for the fiscal year ended September 30, 2023 and related management’s discussion and analysis to both its registered and non-registered shareholders (the “Shareholders”). Using notice-and-access, the Company can deliver proxy-related materials by (i) posting the Information Circular and other proxy related materials on a website other than sedarplus.ca (instead of mailing them to Shareholders), and (ii) sending a notice informing Shareholders that the Information Circular and other proxy related materials have been posted online and explaining how to access such materials. Notice-and-access reduces the Company’s printing and mailing costs and is environmentally friendly as it reduces paper and energy consumption.

Under notice-and-access, Shareholders still receive a proxy or voting instruction form enabling them to vote at the Company’s meeting.
