Broadcom said that their goal is $8.5B in operating margin in 3 years. VMware operating margin today is $4.7B. To get an incremental $3.8B in profitability is not going to come from revenue growth. VMware had 37K employees. To get to Broadcom's profitability goals they will need to get to a target of 16K VMware employees in 3yrs. You divide the $3.8 billion by $175,000 average cost per employee and it equals 21,000 layoffs. See the linked deck with the projected synergy plans for Broadcom on VMware. This average cost includes typical benefits but not the burden of the office real estate.
