Here's your morning TNB Tech minute for Monday, August 18th. I'm Ariana Aspuru for the Wall Street Journal. Google is increasing its investment in the bitcoin miner and artificial intelligence computing company terrawolf to roughly $3.2 billion. This raises its equity stake to about 14%. Terra Wolf said that Alphabet's Google will provide an incremental $1.4 billion backstop to support project related debt financing. In exchange, Google will receive warrants to buy 32.5 million shares of TerraWolf. The funding supports Terra Wolf's Lake Mariner data center expansion, adding 160 megawatts for FluidStack, with operations expected to start in the second half of 2026. Plus Swiss tech company U Blox says Advent International has agreed to buy the company for about $1.3 billion via a public tender offer. U Blox, which is the provider of wireless and positioning semiconductors, said Advent's subsidiary launched an offer to buy it for roughly 1.05 billion Swiss francs in cash. Shares of U Blocks will be delisted from the six Swiss exchange after the deal is completed. The transaction, which is subject to approval, is expected to be settled within the next six months. U Blox executives said the move will help the group pursue its long term strategic objectives with greater flexibility, backed by a strong and experienced financial partner. Finally, in a research report, CGS analysts say CSE Global seems to be laying groundwork for steady data center growth via recurring maintenance contracts. The technologies company's data center segment has quickly scaled by delivering three year compound annual growth rate of over 150% and securing around $79 million in new US data center contracts year to date. That's your TNB Tech Minute. Join us again this afternoon for more.
