As of Q4'25, UnitedHealth Group (UNH) reported operation income of USD 380M, marking a significant decline from previous quarters. The year-over-year growth rate for this period plummeted to -95.1%, indicating a sharp contraction in operational profitability. From Q1'23 to Q1'25, operation income generally ranged between USD 7.7B and USD 9.1B, with moderate fluctuations and occasional growth, as reflected by positive YoY rates in most quarters. However, beginning in Q2'25, there was a dramatic downturn: operation income dropped to USD 5.2B in Q2'25 and further to USD 3.4B in Q3'25, before collapsing to USD 380M in Q4'25. This steep decline is mirrored in the YoY growth rates, which turned sharply negative from Q2'25 onward, highlighting a sudden and severe deterioration in operational performance after a period of relative stability. The chart covers the period from Q1'23 to Q4'25.
