Cloudflare Sales Up 39%, Gross Margin Falls: Rapid Earnings Reaction

NET jumped 15% in after-hours trading after Cloudflare posted Q3 revenue growth of 39% to $782.5 million, with annualized revenue now above $3 billion.

The market is rewarding the top line and looking past the cost side of the report. Gross margin fell 3 points to 71.2%, because cost of revenue grew 54%, well ahead of the 39% sales growth. Free cash flow margin slipped to 10% from 13%, and GAAP operating losses widened. The report ties those pressures to rapid expansion and network capacity investments.

Interpretation: a 15-point gap between cost growth and revenue growth is a meaningful divergence. The after-hours move suggests buyers are treating the margin compression as the price of growth rather than a thesis breaker. That reading holds only while revenue acceleration keeps outrunning the cost build. If sales growth cools while capacity spending stays elevated, the same numbers would look very different.
