An analysis of the reportable segment profit margins from 2020 through 2022 reveals a general trend of margin expansion followed by a period of relative stabilization. Both the MedSurg and Cardiovascular segments experienced their most significant growth in 2021, followed by marginal contractions in 2022.

MedSurg Segment Profit Margin
The MedSurg segment maintained a consistently higher margin profile compared to the Cardiovascular segment. Starting at 30.07% in 2020, the margin expanded to a peak of 33.02% in 2021. A slight decrease was observed in 2022, with the margin settling at 32.13%, representing an overall increase of 206 basis points over the three-year period.
Cardiovascular Segment Profit Margin
The Cardiovascular segment demonstrated a more aggressive recovery and expansion trend. The profit margin rose substantially from 17.64% in 2020 to 26.18% in 2021, marking a significant increase of 854 basis points. This performance remained largely stable through 2022, ending the period at 25.89%.

Comparatively, the disparity in profitability between the two segments narrowed significantly over the observed period. While MedSurg remains the more profitable segment, the Cardiovascular division's rapid margin growth between 2020 and 2021 reduced the margin gap between the two reportable segments from 12.43 percentage points to approximately 6.25 percentage points by the end of 2022.

= 100 × 1,625 ÷ 2,501 = 64.97%


The MedSurg segment demonstrated consistent growth in both operating income and its asset base between 2020 and 2022, although the efficiency of asset utilization experienced some volatility.

Operating Income Growth
Operating income increased steadily over the three-year period, rising from US$ 1,156 million in 2020 to US$ 1,524 million in 2021, and reaching US$ 1,625 million by December 31, 2022. This indicates a consistent upward trend in the segment's absolute profitability.
Asset Expansion
Total assets allocated to the segment grew concurrently, moving from US$ 1,992 million in 2020 to US$ 2,178 million in 2021, and further expanding to US$ 2,501 million in 2022. The steady increase in assets suggests ongoing investment in the segment's operational infrastructure.
Segment Return on Assets (ROA)
The Segment ROA exhibited a fluctuating trend. After an initial increase from 58.03% in 2020 to a peak of 69.97% in 2021, the ratio moderated to 64.97% in 2022. The decrease observed in 2022 is the result of asset growth outpacing the growth in operating income during that period, which led to a slight reduction in overall asset efficiency despite the continued increase in total earnings.

1 2022 Calculation
Segment ROA = 100 × Operating income ÷ Total assets
= 100 × 2,113 ÷ 5,205 = 40.60%


The Cardiovascular segment demonstrated a strong upward trajectory in profitability and asset efficiency from 2020 to 2022. While both operating income and total assets increased throughout the period, the rate of income growth significantly outpaced asset expansion in the initial phase, leading to a substantial peak in asset productivity.

Operating Income Growth
A consistent increase in operating income is observed, rising from 1,043 million USD in 2020 to 2,113 million USD by 2022. The most aggressive expansion occurred between 2020 and 2021, where income grew by approximately 81%, indicating a sharp improvement in the segment's operational profitability.
Asset Base Expansion
Total assets grew steadily over the three-year period, increasing from 3,934 million USD in 2020 to 5,205 million USD in 2022. This represents a cumulative increase of approximately 32%, suggesting ongoing investment in the segment's infrastructure or resource base.
Segment Return on Assets (ROA) Trends
The Segment ROA surged from 26.51% in 2020 to a peak of 42.74% in 2021, driven by the disproportionate growth of operating income relative to assets. In 2022, the ROA experienced a slight contraction to 40.60%. This marginal decline is attributable to the fact that asset growth in 2022 (17.8%) exceeded the growth rate of operating income (11.9%) for that same year.
