Executing a Retail Investor Marketing campaign for Z Squared Inc. Client: Z Squared Inc. Delivered on: 2/24/26 Submitted by: Retail Sparks

OVERVIEW AND GOALS 1 Dear Ryan, In the world of retail investor marketing, the term “proper marketing campaign” has been tossed around so much that it risks becoming a cliché. But here’s the reality: retail investors demand more than buzzwords — they seek transparency, engagement, and value. If we had a Bitcoin for every generic retail investor marketing promise, we’d be crypto tycoons. We are thrilled to present a tailored strategy to engage and captivate retail investors, combining data - driven insights and interactive content. Our retail investor marketing strategy focuses on engaging and educating your audience through interactive content, community - building, and targeted outreach. We will execute a series of initiatives designed to build trust, foster transparency, and drive participation across key platforms. Key deliverables include: • Launch and manage the official Z Squared retail investor subreddit to cultivate a strong and engaged retail shareholder base on Reddit. • Post regular updates across multiple potent retail investing social media communities to reach active retail investor traders and long - term investors. • Host high - impact AMAs and executive interviews across X, YouTube, and Discord, spotlighting Z Squared's milestones, partnerships, and upcoming company updates. • Monthly live sessions hosted on Retail Sparks financial partner networks, connecting Z Squared with tens of thousands of active retail investors on a monthly basis. • Publish due dillegence reports in key retail investor platforms and execute monthly content marketing campaigns that will garner multi - platform visibility across Reddit, X, Stocktwits, and Discord. It has been great speaking with you and we are excited to partner with you to deliver the best results possible moving forward. We are looking forward to discussing next steps with you. Sincerely, Retail Sparks Team
