Intel Foundry Business To Become a Subsidiary | The Gestalt IT Rundown: September 18, 2024

September 18, 2024

We have talked at length this year about Intel’s efforts to turn the ship and add more profitability to the ledger. One of the crown jewels in that portfolio is the foundry business. It has been the recipient of a large amount of government funding through the CHIPS Act. But it is also playing catch up with TSMC and others. New broke yesterday that Intel has announced that the foundry business will be spun off into separate subsidiary entity. The new unit will have it’s own board and be free to seek outside funding, perhaps even going public at some point. Intel stock jumped 8% in after hours trading on the news.

Broadcom Sued by AT&T | The Gestalt IT Rundown: September 11, 2024

September 11, 2024

AT&T has decided enough is enough. They have filed a lawsuit over the tactics they claim are putting first responders and critical government services at risk. AT&T is claiming breach of contract because of the new support policy enacted by Broadcom after the VMware acquisition. The key point comes in an amendment in their support agreement that says that AT&T can renew their current support contracts for up to two more years provided they do so before the expiration of their current contract. They are exercising that option now but VMware by Broadcom is not honoring the renewal. AT&T stated they don’t have an issue with the business model change, just that it affects them right now and is making them pay more.
