The filings do not say who else is in the group, so FloatCap does not split it between team and outside investors. Derived from the 424B4 release table (351.9 million shares = 20% of the group).
"Gwynne Shotwell, President, Chief Operating Officer and a director, agreed to subject the vast majority of her shares to the extended lock-up period."
