To our Shareholders:

Fiscal 2025 has been an exciting year of progress for HydroGraph as we moved to advance our science, engineering, production and sales capabilities, all with one goal in mind – to commence commercial sales of our 99.8% pure carbon fractal graphene products. I am pleased to say that we have made considerable progress on all of these points and continue to build on these accomplishments as we begin Fiscal Year 2026.

Our commercial sales pipeline is robust and continues to expand, with more than 65 projects in various stages of development. These range from small but critical applications of graphene such as medical devices to very large and diverse end markets that could consume hundreds of tons at full scale, such as composites and coatings. We are working closely with multiple counterparties to commercialize these applications at scale, and this is our number one priority. We look forward to making announcements as these efforts reach final agreement.

To get to these commercial opportunities, we have also advanced our science and engineering capabilities, building what we believe might be one of the most comprehensive libraries of graphene applications in partnership with both our commercial counterparties and the GEIC (Graphene Engineering and Innovation Centre in Manchester, UK). HydroGraph and its partners have become well known as experts in how to actually deploy graphene into materials and innovative new applications – working through the chemistry and production intricacies needed to produce repeatable, effective and reliable outcomes. In doing so, we have also documented how purity and consistency play a critical role in success, further differentiating our batch consistent fractal aggregates.

Those efforts have yielded not just commercial knowledge but new innovations in graphene science. We were excited to recently announce the first of what we hope will become many graphene related patents that come entirely from HydroGraph’s innovation work. These patentable discoveries are in addition to the engineering and working knowledge specific to incorporating graphene into a growing number of applications.

To date, HydroGraph has produced approximately one ton of graphene, which took about six weeks to complete. To advance our readiness to provide commercial quantities, we have taken steps to expand our production capacity, both at our existing facilities and new sites. Currently, with one Hyperion Reactor and existing acetylene supply, we can produce about one ton per month. The primary limiting factor is access to acetylene, our key input. At our Manhattan, KS offices, we have upgraded our acetylene storage systems and have second and third Hyperion Reactor units in production, which will enhance our supply capability for initial engagements. With these additional reactors, we expect to scale to approximately 30 tons per year. We also announced the lease on a new Austin, TX facility, which will house operations, research and production capabilities, and the remote control of future production facilities with construction set to begin soon for an opening date Spring 2026. We expect this site will also facilitate up to two Hyperion units, similar to our Manhattan site.
