Big picture, insurers generate revenue from three key sources. The first is the core business of underwriting policies. The second source is income from investing the “float” (premiums collected upfront not yet paid out as claims) in assets such as fixed-income assets and equities. The third is fees from various sources such as policy administration, annuities, or other value-added services. Luckily, Root’s revenue grew at an incredible 34.3% compounded annual growth rate over the last five years. Its growth beat the average insurance company and shows its offerings resonate with customers.

When insurers sell policies, they protect themselves from extremely large losses or an outsized accumulation of losses with reinsurance (insurance for insurance companies). Net premiums earned are therefore gross premiums less what’s ceded to reinsurers as a risk mitigation and transfer strategy.

Root’s net premiums earned has grown at a 34.2% annualized rate over the last five years, much better than the broader insurance industry and in line with its total revenue.

When analyzing Root’s net premiums earned over the last two years, we can see that growth accelerated to 87.2% annually. Since two-year net premiums earned grew faster than total revenue over this period, it's implied that other line items such as investment income grew at a slower rate. While these additional streams certainly contribute to the bottom line, their impact can vary. Some firms have shown greater success and long-term consistency in investing their float compared to peers. However, sharp fluctuations in the fixed income and equity markets can significantly affect short-term performance.
