Sphere 3D shareholders approve merger with Cathedra Bitcoin, closing

Sphere 3D’s shareholders gave the green light to its merger with Cathedra Bitcoin at a special meeting on May 15, clearing the final corporate hurdle before the deal closes on June 1, 2026. The all‑stock transaction, first announced on March 5, will leave Cathedra shareholders with roughly 49% of the combined company on a partially diluted basis, while Sphere retains its NASDAQ listing and corporate identity [1].

The combined entity will control 53 megawatts of power across five data‑center sites in Iowa, Kentucky and Tennessee, delivering more than 1.2 exahash per second of Bitcoin mining capacity. Management plans to use the geographic diversity to keep mining operations running while gradually converting capacity to high‑density AI and high‑performance computing workloads, a pivot already hinted at by a new hosting agreement that occupies about 80% of Cathedra’s 15 MW Shire site in Kentucky [1]. The merger also gives Sphere access to Cathedra’s established power infrastructure and site‑development expertise, while Cathedra gains a public‑market parent with broader capital‑raising options [1].

Beyond the technical assets, the deal reshapes the balance sheet. The combined firm will operate debt‑free with an unencumbered asset base, enhancing financial flexibility for future upgrades or site acquisitions, according to the company’s filing [2]. However, the 49% equity stake for Cathedra shareholders translates into notable dilution for existing Sphere holders, a point analysts flag as a risk amid the company’s ongoing revenue decline and cash burn [2][3].

Investors should watch two near‑term catalysts: the speed at which additional AI‑hosting contracts materialize beyond the Shire site, and any concrete timelines for retrofitting the power‑ready facilities. Both will determine whether the 53 MW platform can generate higher revenue per megawatt than pure Bitcoin mining, a shift that could improve the company’s cash flow outlook. The merger’s success hinges on executing that transition while managing dilution and the broader market’s appetite for crypto‑linked infrastructure.
