Tether's Pre-Funded Warrant Issuance Under Transaction Support Agreement with RUM Group

According to the filing, the September 2, 2026, transaction was made pursuant to a Transaction Support Agreement (the "TSA") dated November 10, 2025, between Tether Investments, S.A. de C.V. and RUM Group Inc. (formerly known as Rumble Inc.). Under the TSA, the filing states that the issuer is obligated to issue to Tether Investments 2.0281 shares of Class A Common Stock for each no-par value bearer share of Northern Data AG sold to the issuer by Tether Investments, up to one year following the closing as defined in the TSA.

The filing further explains that, to the extent such issuances would cause Tether Investments and its affiliates to own more than 9.9% of the outstanding voting power of the issuer's capital stock (described in the filing as the "Voting Limitation"), the issuer instead delivers a pre-funded warrant exercisable on a cashless basis, so that the shares to be owned by Tether Investments and its affiliates following the closing will not exceed that threshold. The newly reported warrant covers 16,744,307 shares, is exercisable beginning September 30, 2026, and expires September 30, 2036.

The filing identifies the shares as directly held by Tether Investments, S.A. de C.V., a wholly-owned subsidiary of Tether Global Investments Fund, S.I.C.A.F., S.A. (formerly known as Tether Holdings, S.A. de C.V.). Giancarlo Devasini is described in the filing as indirectly holding voting and dispositive power over securities held by Tether Global Investments Fund, including those held by Tether Investments. The filing notes that each reporting person "disclaims beneficial ownership of the reported shares other than to the extent of any pecuniary interest they may have therein, directly or indirectly."
