Datacentrex, Inc.

Company Overview Datacentrex, Inc. (formerly, Thumzup Media Corporation), a Nevada corporation ( Datacentrex, the Company, we, us, or our ) is a digital infrastructure and capital deployment company that owns and operates Scrypt compute assets and evaluates strategic transactions across asset-backed operating businesses. Our current operating platform is centered on owned and operated Scrypt-based proof-of-work ( PoW ) compute deployed through third-party colocation facilities. We monetize this compute primarily through hashrate marketplace mechanisms and manage a treasury of digital assets and cash in a manner intended to preserve capital and support opportunistic, accretive deployment. Our Scrypt compute operations utilize specialized application-specific integrated circuit ( ASIC ) hardware to contribute hashrate to the Litecoin blockchain. Through merged-mining architecture, that same hashrate can simultaneously secure and validate additional Scrypt-based networks, including Dogecoin and other auxiliary Scrypt chains, without incremental energy consumption. This merged-mining attribute allows a single deployment of compute and power to produce economic exposure to multiple networks, subject to protocol rules and monetization mechanics. On August 18, 2025, Datacentrex, entered into an Agreement and Plan of Merger with TZUP Merger Sub, Inc., a wholly-owned subsidiary of the Company, and Dogehash Technologies, Inc. ( Doge ), a Nevada corporation, pursuant to which the Company agreed to acquire Doge (the Merger ).
