none (unless you count google and meta),

but profitability is a very narrow view on the labs, and investors are pricing in future free cash flow

you need to take into account the derivative, what is their growth? their opex and capex? their revenue growth? their moat? New product lines and applications?

Not saying that it's a homerun, but there is a case to be made for the labs being wildly profitable in 4-10 years
