As of Q4'25, Amazon's diluted EPS reached 1.95 USD, maintaining the same level as the previous quarter and marking the highest value in the observed period. Year-over-year EPS growth for Q4'25 slowed significantly to just 4.8%, indicating a sharp deceleration compared to earlier quarters. From Q1'23 to Q4'25, Amazon's diluted EPS showed a consistent upward trend, rising from 0.31 USD to 1.95 USD. The most notable acceleration occurred between Q2'23 and Q4'24, with EPS nearly tripling and YoY growth peaking at 49.5% in Q4'23. However, after Q4'23, the pace of growth moderated, with YoY EPS growth steadily declining each quarter, suggesting that while earnings continue to expand, the rate of improvement is tapering off as the company matures.
