Dear [Brand] Distributors,


I want to take this opportunity to share a public notification sent through a press release on Friday June 25, 2021. I have attached that press release to this letter for your review. I also want to make sure the press release does not cause confusion or concern with our valued distributors and customers.


IKONICS has entered into a merger agreement with TeraWulf Inc., a bitcoin mining and high-performance computing company.


We believe the merger agreement provides ideal outcomes for IKONICS shareholders, customers, and employees. The agreement is instrumental in securing the long-term viability of the IKONICS’ legacy businesses, allowing it to continue to meet the needs of customers with a secure supply of high-quality products and expanded employment opportunities for our workforce.


Because this is a somewhat complicated public process, there are many details we are not currently able to share. Rest assured that we will continue normal operations for the foreseeable future and this move will allow IKONICS to continue to supply you with our great products for years to come.


While we are very excited, today’s news is just the first step in the process. Pending shareholder approval and customary closing conditions, we expect the transaction will close during the second half of 2021. In the meantime and even after the mergers are completed, [Products] will operate consistent with past practices and your supply and service from [Brand] will not change. Currently, shipping lead times have been extended due to raw material shortages and shipping delays caused by port back-ups and congestion. We expect this to subside soon, and it is not an impact of the merger. Please keep this in mind when issuing purchase orders for product.


Thank you for your business and continued loyalty. If you have any questions regarding the situation, please contact Ken Hegman, IKONICS Chief Operating Officer, at phone 218-628-6434 or email: We look forward to growing with you in the future!


Best Regards,


Glenn Sandgren
