(TSX: NXE) (NYSE: NXE) (ASX: NXG) (“NexGen” or the “Company”) is proud to announce the launch of its largest ever scholarship program, with the award of 8 scholarships for the 2025-26 academic year, doubling the number of young LPA leaders who will launch from their post-secondary academic pursuits as well as continued mentorship and employment opportunities. These students have all been through NexGen’s extensive community focused programs and are members of the LPA communities highlighting NexGen’s long-term focus on a holistic approach to community and career advancement initiatives.

Initiated in 2017, NexGen’s scholarship program identifies these students in partnership with education institution faculty in the LPA and provides pathways for students attending post-secondary education. To date, the program has awarded 38 scholarships, supporting young community leaders across a broad range of academic pursuits including Trades, College, and University programs.

Leigh Curyer, Chief Executive Officer, commented: “We are extremely proud to be expanding this important program for the benefit of motivated and deserving young leaders from across the LPA. These scholarships represent an average of $10,000 per year for each of the 38 students to date covering their educational needs for advanced technical studies. The scholarship program compliments a series of long-standing impactful initiatives that NexGen has been driving since 2013, focused on mentoring and empowering LPA youth to achieve personal and academic success at unprecedented levels. From health and wellness, to education, to trades training and certification for long-term careers, we look forward to seeing the exponential growth of all these programs when construction commences immediately upon final Federal approval of our generational Rook I Project. On behalf of the entire NexGen team, we congratulate this dedicated group of students on their scholarship awards and look forward to continuing to mentor and support them through their academic and professional journey.”
