The analysis of the quarterly financial data reveals several notable trends in revenue composition, cost structure, profitability, and income dynamics over the periods examined.

Revenue Composition

The share of premiums as a percentage of revenues remained relatively stable, fluctuating around the high seventies, generally between approximately 77% and 80%, indicating a consistent reliance on premiums as the primary revenue source. Products accounted for roughly 11% to 13.5% of revenues, showing mild variability but a slight upward trend in the latest quarters. Services contributed about 7% to 9.5%, with a gradual increase observed particularly from late 2020 onward.

Cost Structure

Medical costs consistently constituted the largest portion of costs, ranging from approximately -56% to as high as -71% of revenues, with a general increasing trend, particularly notable toward the later periods where it deepened significantly. The cost of products sold remained relatively stable around the -10% to -12.5% band, though showing a slight uptick in the latter quarters. Overall cost of revenues, aggregating these costs, hovered mostly between -68% and -83%, with a discernible increase in cost burden over time, especially in the most recent quarters.

Profitability Indicators

Gross profit margins, calculated as percentages of revenues, fluctuated between approximately 17% and 32%. Noteworthy is the peak in mid-2020, followed by a tapering trend toward the end of the dataset with margins dipping below 20% in recent quarters. Operating costs as a percentage of revenues maintained a relatively narrow range, generally between -12.5% and -17.7%, showing a tendency to decrease slightly in later periods, suggesting some operational cost discipline. Depreciation and amortization remained fairly steady around -1%, with minor fluctuations, indicating stable fixed asset utilization.

Earnings and Income Trends

Earnings from operations showed volatility, with peaks exceeding 14% early in the dataset, declining thereafter to a range mostly between 4.5% and 9.5%. This suggests pressure on core operational profitability. Interest expense as a percentage of revenues remained below -1%, with a modest increasing trend in recent quarters, potentially indicating slightly higher financing costs. Losses on sale of subsidiaries appeared sporadically in late periods, with a notable one-time large negative impact of over -7% in late 2024, affecting overall earnings.

Income Tax and Net Earnings

The provision for income taxes fluctuated moderately, typically around -1% to -1.9% of revenues, with some reduction observed in the latest quarters. Net earnings as a percentage of revenues showed substantial variability, peaking above 10% in mid-2020 and generally ranging between 3% and 7% subsequently. A significant negative net earning of approximately -1.24% was recorded in early 2024, coinciding with operational challenges or extraordinary items. Earnings attributable to common shareholders followed a similar pattern, reflecting consistent minority interest deductions.

Overall Observations

The financial data illustrates consistent revenue composition dominated by premiums, with slight growth in services contribution. Rising medical and product costs have exerted downward pressure on gross margins, particularly in recent periods. Operational efficiencies appear to have been pursued, as evidenced by slightly declining operating costs relative to revenues. Profitability metrics, including operating earnings and net earnings, demonstrate episodic volatility with some notable one-time charges impacting results. The pattern suggests an environment of increasing cost challenges balanced by disciplined expense management to support earnings stability.
