Arista Networks Inc. (NYSE:ANET)

The return on equity (ROE) exhibited a generally positive trend over the observed period, though with notable fluctuations. Initial values were in the mid-teens, increasing significantly in later years. Stockholders’ equity consistently increased throughout the period, while net income demonstrated more variability.

Overall Trend

From 2014 to 2025, ROE generally increased, moving from 15.63% to 28.39%. The period between 2014 and 2017 showed a substantial increase, followed by a dip in 2018, and then a significant surge through 2019. The subsequent years maintained ROE in a range between approximately 19% and 29%.

Early Period (2014-2017)

ROE began at 15.63% in 2014 and experienced moderate growth in 2015 (15.37%). A more pronounced increase occurred in 2016 (16.63%), culminating in a substantial jump to 25.46% in 2017. This period coincided with a rapid increase in both net income and stockholders’ equity.

Mid-Period (2018-2021)

In 2018, ROE decreased to 15.31%, despite continued growth in stockholders’ equity. This suggests a slower growth rate in net income relative to equity. ROE then rebounded strongly in 2019, reaching 29.71%, driven by a significant increase in net income. The years 2020 and 2021 saw ROE at 19.11% and 21.13% respectively, indicating a stabilization after the 2019 peak.

Recent Period (2022-2025)

ROE increased to 27.68% in 2022, followed by 28.91% in 2023, and a slight decrease to 28.39% in 2025. This recent period demonstrates a high and relatively stable ROE, supported by substantial growth in both net income and stockholders’ equity. The rate of increase in net income appears to be moderating relative to the growth in equity in the final observed year.

Net Income and Equity Relationship

The consistent growth in stockholders’ equity suggests a strong ability to retain earnings and potentially issue new equity. Fluctuations in ROE are primarily driven by changes in net income, as evidenced by the significant increases in ROE coinciding with substantial net income growth in 2017 and 2019. The continued growth in equity alongside relatively stable ROE in the later years suggests a potential diminishing return on equity, requiring further investigation.
