However, these last three years, the Magnificent-7 companies are still growing their revenues by 15–20 per cent, despite almost no headcount expansion, hence the scope for margin expansion. Just for context, in their latest quarter, Alphabet grew revenues by 14 per cent, Meta by 22 per cent and Microsoft by 18 per cent. For operating margins, Alphabet at 32.5 per cent, Meta at 43 per cent and Microsoft at 45 per cent all reported an increase. They have been able to increase operating margins despite raising capex guidance to $75–80 billion each and surging research and development (R&D) costs. The margin increase has come from lowering the selling, general and administrative (SG&A) expenses as a percentage of revenue.
