Full control of Northern Data AG is within reach for RUM Group Inc. (Nasdaq: RUM), which expects to lift its stake from 85.2% to approximately 98% before triggering squeeze-out proceedings under Germany's Stock Corporation Act to take the remainder. The risk is that the price paid in that squeeze-out may not match what bilateral traders, including Tether Investments, S.A. de C.V., have paid.
The Tether exchange and what moves on September 30
The additional shares are flowing from Tether under a Transaction Support Agreement already in place. The terms: Tether agreed to exchange, at the end of each calendar month, any additional Northern Data shares it acquired for pre-funded warrants in RUM Group (Nasdaq: RUMBW) at a fixed ratio of 2.0281 RUM Class A common shares per Northern Data share delivered. On September 2, 2026, Tether reported agreeing to acquire 8,256,155 Northern Data shares. Those acquisitions are expected to settle in time for an exchange with RUM Group on or about September 30, 2026.
Once that exchange closes, RUM Group will submit a formal squeeze-out request to Northern Data. Germany's Stock Corporation Act allows a majority shareholder above a qualifying threshold to compel buyout of remaining minority holders, but the statute sets valuation through an independent process. What minorities receive may differ from market prices or the cost Tether is accepting.
The read-through to Maysville
The consolidation notice comes alongside a previously disclosed $13.7 billion GPU services agreement with an unaffiliated U.S.-based third-party cloud customer for RUM Group's site in Maysville, Georgia. The case for linking the two: Northern Data, which the filing describes as a provider of AI and high-performance computing infrastructure, is the operational substrate of that agreement. Full ownership eliminates governance friction that a minority float creates when RUM Group is committing capacity and capital at that scale.
The counterargument is structural and worth naming. German squeeze-out proceedings invite valuation challenges from minority shareholders, and those challenges can run for years in court. RUM Group acknowledges in its filing that the squeeze-out price may differ from market prices and from what Tether paid, which is a public concession that the independent valuation process carries litigation risk. Executing a $13.7 billion services contract while absorbing that overhang is not a clean operating picture.
On balance, the unit economics of consolidation favor completion. Full revenue recognition from Northern Data's AI compute capacity, without minority drag on governance, fits the logic of RUM Group's Quake AI compute-as-a-service build. The line to watch is whether the September 30 Tether exchange settles cleanly and, after that, what valuation Northern Data's remaining shareholders receive in the squeeze-out.
