Question

What we set out to check

Why Alphabet's shares fell, the key Q3 numbers, and how Microsoft's quarter compared.

Findings

What we found

Trefis and TOPONE Markets agree on the share drop, revenue, cloud growth, capex, free cash flow and guidance. TOPONE adds the backlog and the market value lost. SiliconANGLE gives Microsoft's figures.

Discrepancies

Numbers that differ

Trefis gives the EPS estimate as $3.02; TOPONE notes an $8.2 billion loss tied to the SpaceX stake that affected EPS. We mention both.

Method

Labels we chose and why

Reported for Alphabet figures in both sources. Unconfirmed for Microsoft figures, from one source.

Open questions

What we could not verify

Alphabet's own earnings release, which we did not open directly.
