> Amazon’s operating income in 2024 improved 86% YoY, from $36.9B (an operating margin of 6.4%) to $68.6B (an operating margin of 10.8%). Free Cash Flow, adjusted for equipment finance leases improved from $35.5B in 2023 to $36.2B.

Can someone help me understand these numbers. Their operating income improved (increased?) by 86% but margin only ~4%?

Does that mean most of the improved (increased?) operating income was put towards capital outflow?
