Revenue growth

Insurers earn revenue three ways. The core insurance business itself, often called underwriting and represented in the income statement as premiums earned, is one way. Investment income from investing the “float” (premiums collected upfront not yet paid out as claims) in assets such as fixed-income assets and equities is the second way. Fees from various sources such as policy administration, annuities or other value-added services are the third. RenaissanceRe’s revenue grew at a strong 12.8% compounded annual growth rate over the last five years. Its growth beat the average insurance company and shows its offerings resonate with customers.

Long-term growth matters the most, but within financials, a half-decade historical view may miss recent interest rate changes, market returns and industry trends. RenaissanceRe’s recent performance marks a sharp pivot from its five-year trend as its revenue has shown annualized declines of 12.7% over the last two years. Note: Quarters not shown were determined to be outliers because they were impacted by outsized investment gains/losses that are not indicative of the recurring fundamentals of the business.

This quarter, RenaissanceRe missed Wall Street’s consensus estimates and reported an uninspiring 47.1% year-on-year revenue decline, generating $1.69 billion of revenue.

Net premiums earned made up 89% of the company’s total revenue during the last five years, meaning RenaissanceRe barely relies on non-insurance activities to drive its overall growth.

The market focuses primarily on an insurer’s net premiums earned growth as investment and fee income are considered more susceptible to market volatility and economic cycles.

Book value per share (BVPS)

Insurance companies are balance sheet businesses, collecting premiums upfront and paying out claims over time. The float – premiums collected but not yet paid out – is invested, creating an asset base supported by a liability structure. Book value captures this dynamic by measuring:

• Assets (investment portfolio, cash, reinsurance recoverables) - liabilities (claim reserves, debt, future policy benefits)

BVPS is essentially the residual value for shareholders.

BVPS is therefore important to track for insurers and sheds light on business quality. While other, more commonly known per-share metrics like EPS can sometimes be lumpy due to reserve releases or one-time items and can be managed or skewed while still following accounting rules, BVPS reflects long-term capital growth and is harder to manipulate.

RenaissanceRe’s BVPS grew at a strong 15% annual rate over the last five years. BVPS growth has recently slowed slightly to 13.4% annually over the last two years (from $202.01 to $259.61 per share).

Key takeaways from RenaissanceRe’s Q3 results

RenaissanceRe’s revenue and EPS both fell short of Wall Street’s consensus estimates, leaving few positives in a softer quarter. Shares remained flat at $341.15 immediately after the results.

RenaissanceRe underperformed this quarter, but that alone doesn’t determine whether the stock offers an investment opportunity. The latest quarter is only one part of the longer-term business quality picture. Quality, when combined with valuation, can help determine if the stock is a buy.
