Between 2017 and 2021, the Return on Invested Capital (ROIC) exhibited a trajectory of early growth followed by a significant contraction and a subsequent period of stabilization. The overall trend indicates a decline in capital efficiency over the five-year period, as the expansion of the invested capital base outpaced the growth in net operating profit after taxes (NOPAT).

Net Operating Profit After Taxes (NOPAT)

NOPAT demonstrated an initial increase, rising from 1,952 million US$ in 2017 to a peak of 2,286 million US$ in 2018. However, this growth was not sustained, with a decline observed in 2019 and 2020. By 2021, NOPAT showed a slight recovery to 2,064 million US$, though it remained below the 2018 peak.

Invested Capital

A consistent upward trend in invested capital was observed for the majority of the period. The most significant expansion occurred between 2018 and 2019, where invested capital grew from 18,435 million US$ to 22,640 million US$. The capital base reached its maximum in 2020 at 23,729 million US$ before experiencing a slight reduction to 22,932 million US$ in 2021.

Return on Invested Capital (ROIC)

The ROIC peaked in 2018 at 12.40%, driven by the simultaneous increase in NOPAT and a relatively modest increase in invested capital. A sharp decline followed in 2019, with the ratio dropping to 9.36%, which correlates with the substantial increase in the invested capital base during that year. The ratio reached its lowest point in 2020 at 8.50% before trending slightly upward to 9.00% in 2021.

The analysis suggests that the decline in ROIC from 2018 to 2020 was primarily driven by the rapid expansion of invested capital, which occurred while operating profits were simultaneously contracting. The marginal improvement in 2021 reflects a stabilization phase where a slight increase in NOPAT coincided with a reduction in total invested capital.

The Return on Invested Capital (ROIC) exhibited significant volatility between 2017 and 2021, peaking at 12.40% in 2018 before declining to a low of 8.50% in 2020 and partially recovering to 9.00% in 2021. This trajectory was primarily driven by fluctuations in operating profitability and capital efficiency.

Operating Profit Margin (OPM)

Profitability peaked in 2018 at 18.73% but entered a consistent downward trend thereafter, reaching 15.32% by 2021. This contraction in margin served as a primary headwind to the overall return on capital during the latter half of the period.

Turnover of Capital (TO)

Capital efficiency showed a marked decline from 0.82 in 2017 to a trough of 0.64 in 2020. However, a significant recovery occurred in 2021, with the ratio rising to 0.78. This rebound in turnover was the principal driver for the slight increase in ROIC observed in the final year of the analysis.

Effective Cash Tax Rate Impact (1 – CTR)

The after-tax retention component of the return increased steadily from 75.72% in 2017 to a peak of 86.16% in 2020, which provided some cushion against falling margins and turnover. A sharp reversal occurred in 2021, where the value dropped to 74.98%, limiting the potential gains from the improved capital turnover.

The decomposition of ROIC reveals that the performance peak in 2018 resulted from the synergy of maximum operating margins and high capital turnover. The subsequent decline was a result of simultaneous erosion in both margin and turnover. The modest recovery in 2021 indicates a shift in the return driver, where improved asset utilization (Turnover) compensated for declining operating margins and a higher effective tax burden.

An analysis of the financial performance between 2017 and 2021 reveals a divergence between revenue growth and operating efficiency. While adjusted operating revenues exhibited a general upward trajectory, the operating profit margin experienced a consistent decline following a peak in 2018.

Revenue Growth Trends

Adjusted operating revenues increased from US$ 14,495 million in 2017 to US$ 17,963 million in 2021. This growth was relatively steady until 2020, followed by a significant surge in 2021, where revenues grew by approximately 18% compared to the previous year.

Net Operating Profit Before Taxes (NOPBT) Performance

NOPBT demonstrated volatility over the five-year period, peaking at US$ 2,797 million in 2018. A subsequent decline occurred through 2020, reaching a low of US$ 2,342 million. Although NOPBT recovered to US$ 2,753 million in 2021, the profit level failed to exceed the 2018 peak despite the substantially higher revenue base in the later year.

Operating Profit Margin (OPM) Contraction

The operating profit margin peaked at 18.73% in 2018 before entering a period of steady erosion. The margin fell to 16.44% in 2019 and continued to decrease, ending at 15.32% in 2021. This downward trend indicates that operating expenses scaled more rapidly than revenues, leading to a reduction in the percentage of each revenue dollar that translated into operating profit.

The analysis of capital efficiency from 2017 to 2021 reveals a period of significant capital expansion followed by a recovery in asset productivity. While adjusted operating revenues exhibited an overall upward trajectory, the rate of growth in invested capital initially outpaced revenue generation, leading to a temporary decline in the turnover of capital.

Revenue Dynamics

Adjusted operating revenues grew steadily from 14,495 million USD in 2017 to 15,467 million USD in 2019. After a marginal contraction in 2020 to 15,223 million USD, a substantial increase was recorded in 2021, reaching 17,963 million USD.

Invested Capital Trends

Invested capital rose from 17,686 million USD in 2017 to a peak of 23,729 million USD in 2020. The most pronounced increase occurred between 2018 and 2019, during which capital grew by approximately 22.8%, suggesting an intensive period of investment or acquisition.

Turnover of Capital Efficiency

The turnover ratio experienced a downward trend from 0.82 in 2017 to a minimum of 0.64 in 2020. This decline indicates a period of diminishing efficiency relative to the capital deployed. However, a significant reversal occurred in 2021, with the ratio improving to 0.78, driven by the surge in operating revenues combined with a slight reduction in the total invested capital base to 22,932 million USD.

The effective cash tax rate (CTR) exhibited a distinct cyclical pattern between 2017 and 2021, characterized by a sustained four-year decline followed by a sharp reversal in the final year of the period.

Cash Tax Rate Trajectory

From 2017 to 2020, a consistent downward trend is observed in the CTR, which fell from 24.28% to a period low of 13.84%. This decline represents a reduction of approximately 1,044 basis points over four years, suggesting a period of increased tax efficiency or the impact of significant tax credits and deferred liabilities.

Operating Profit and Tax Correlation

Net operating profit before taxes (NOPBT) remained relatively resilient, fluctuating between a high of 2,797 million in 2018 and a low of 2,342 million in 2020. Despite the stability in operating profit, cash operating taxes decreased more aggressively than profit from 2017 to 2020, dropping from 626 million to 324 million.

Analysis of the 2021 Reversal

The year 2021 marked a significant pivot in the tax profile. The CTR surged to 25.02%, surpassing all previous levels in the analyzed timeframe. This increase was driven by a disproportionate rise in cash operating taxes, which jumped to 689 million—more than double the 2020 figure—while NOPBT grew at a more moderate pace to 2,753 million.
