I report from the stock market – Kinsale Capital 2025 Q4

🙋What does the stock market report section contain?

The “Reporting from the Stock Exchange” column is a kind of compass for investors, helping them navigate the dense data set of listed companies. The essence of the column is not just to report raw numbers, but to professionally process the latest quarterly or annual report of the given company. During each such analysis, we put the most important financial indicators (such as sales, profit, ROCE or ROIC) into context, comparing them with previous expectations and, in some cases, with the performance of competitors. Now I will give my opinion on Kinsale Capital 2025 Q4.

Beyond the dry data, the column pays special attention to reading between the lines: it analyzes management's expectations and future market prospects. We examine how global economic trends, technological shifts (such as the use of AI) or industry specificities may affect the company's long-term growth trajectory. The column aims to provide investors with not only a look at what happened in the past three months, but also what to expect in the market in the coming period. The given quarterly report will also be linked to the in-depth analysis of the stock, if this has already been done on the iO Charts blog.

In the "📌In Practice" section, you can find my comments beyond mere numbers, which take into account qualitative rather than quantitative aspects.

📈 Kinsale Capital (KNSL) Q4 2025 Performance Analysis

Kinsale Capital's strong financial performance in Q4 2025, highlighted by a 26% increase in diluted operating earnings per share and a 26% full-year return on operating equity (ROE), was driven primarily by disciplined underwriting, significant cost advantage and strategic use of technology. Despite facing fierce competition in the E&S (Especialized Risks) market, particularly in the large commercial real estate segment, which has declined as I wrote in my analysis, the company achieved robust growth of 10.2% in gross premium income (excluding commercial real estate).

This growth, coupled with a low combined ratio of 71.7%, which benefited from a 4 percentage point improvement in prior years' reserves and lower catastrophe losses, demonstrates the effectiveness of the low-cost business model, with an expense ratio of under 21%. I should point out that the industry metric is around a 90% loss ratio, which is 18.3% better than the loss ratio in Kinsale Capital's Q4 2025 report, which is evidence of their much better working model. In addition, a 24.9% increase in net investment income, fueled by strong operating cash flow and average new investment returns of 5%, contributed significantly to the bottom line.

📌In practice: Kinsale Capital (KNSL) not only beat analysts' expectations in the fourth quarter, but also produced a 17.3% increase in revenue. It is clear that in the current market sentiment, even on this news, the stock was able to fall by 14%, then corrected back to around -10%.

🔍 I report from the stock market – Kinsale Capital 2025 Q4: key findings

Kinsale Capital's Q4 2025 performance is significantly impacted by the highly competitive E&S market. In particular, due to the high-value, catastrophe-prone commercial real estate business. The contraction in this segment is the main drag on total premium growth. However, the company demonstrates solid internal strength: Gross premium growth excluding commercial real estate was 10.2%, thanks to segments such as small business real estate, various liability insurance lines and residential insurance.

A defining difference is Kinsale's significant cost advantage: the cost ratio of under 21% contrasts with competitors' indicators of around 35% or higher, which is of particular importance in a tightening market cycle. The company is also aggressively leveraging technology and AI, operating a proprietary core system and deploying AI tools across the company to improve productivity, risk segmentation, and pricing. As a sign of confidence and strong capital position, Kinsale Capital 2025 Q4 At the close of the year, it authorized a $250 million share repurchase and increased its quarterly dividend to $0.25, while maintaining its conservative capital levels and a consistent trend of favorable claims reserves.

📌In practice: as a reminder, if the sum of the ratio of write-offs and the expense ratio goes above 100%, insurers become unprofitable. If the expense ratio is low, it allows for very efficient operations, while less efficient insurers exit the market due to loss-making operations. In such cases, Kinsale Capital (KNSL) can absorb these clients as well, so in reality, although the numbers may not necessarily show it, market clearing, i.e. worse periods, are clearly beneficial for efficient insurers.

🔮 Kinsale Capital 2025 Q4: forecast

Following Kinsale Capital's Q4 2025 report, the company provided clear guidance on capital allocation and market expectations. The company plans to use its $250 million share repurchase program over the next year or so, representing a buyback of approximately 2.5%. The quarterly dividend, which was increased to $0.25 per share, is also an effort to increase the amount of excess capital returned to shareholders.

At an operational level, the extremely competitive situation in the large commercial real estate market is expected to persist in 2026, although stabilization is expected after a few quarters. Nevertheless, management is confident that it can continue to generate very high returns for the foreseeable future; the target remains an operating ROE of over 20%, supported by disciplined underwriting and cost advantages. The company will also begin its annual reinsurance program renewal next month, during which it will review its own risk retention levels.

📌In practice: I am not a big fan of paying dividends because it drains away the free cash flow generated, but in this case it is only symbolic. On the other hand, I am a fan of share buybacks, especially when the valuation is so depressed. In practice, this means that Kinsale Capital very rarely trades at such a depressed valuation.
