Intel stock rose Tuesday as speculation mounts about deals to acquire different parts of the chip company. However, there are major hurdles for a reported potential split of the company’s operations between Taiwan Semiconductor Manufacturing and Broadcom.

Intel’s board has been in talks with potential buyers and the U.S. government, The Wall Street Journal said. Former CEO Gelsinger stepped down in December.

Despite its current woes, Intel remains a massive American chipmaker, and the US government will want to ensure that its fabs and technology remain under American control. Broadcom is a US company, but TSMC is based in Taiwan.
