Highlights

  • Tower has rebuilt profitability and significantly increased shareholder returns following a strong underwriting performance.
  • The insurer's ordinary dividend appears supported by earnings and capital strength, but catastrophe claims remain a major risk.
  • Investors should distinguish between recurring dividends and one-off capital returns when assessing future income potential.

Why Is Tower Back on Dividend Investors’ Radar?

Tower Limited (NZX:TWR) has emerged as one of the most notable turnaround stories on the New Zealand stock market. After years of dealing with legacy issues, including the long tail of Canterbury earthquake claims and operational restructuring, the insurer has returned to strong profitability and resumed meaningful capital returns to shareholders.

The company now attracts income investors because of its fully imputed dividend, improved earnings profile, and commitment to returning surplus capital when appropriate. Recent dividend growth has been substantial, making Tower one of the more closely watched income stocks on the NZX.

However, assessing Tower’s dividend sustainability requires a deeper analysis than simply looking at the headline yield. Insurance companies operate differently from most businesses. Earnings can fluctuate significantly depending on weather events, natural disasters, claims experience, and reinsurance costs. As a result, a strong dividend in one year does not necessarily guarantee the same level of income in the next.

The key question for investors is whether Tower's recent shareholder returns represent a sustainable long-term trend or whether they were boosted by unusually favorable conditions.

How Does Tower Generate Earnings?

Tower is a general insurer focused primarily on home, contents, motor vehicle, and personal insurance products in New Zealand, while also maintaining operations in selected Pacific markets.

The insurer earns revenue through premiums collected from policyholders. Profitability depends on maintaining a balance between premium income, claims costs, operating expenses, and reinsurance costs.

One of the most important metrics for evaluating insurers is the combined operating ratio (COR). This measures claims and expenses as a percentage of premium income. A ratio below 100% indicates an underwriting profit, while a ratio above 100% suggests underwriting losses.

Unlike many industries, insurance profitability can change rapidly due to major natural disasters. New Zealand’s exposure to earthquakes, storms, floods, and severe weather events means insurers must maintain substantial reinsurance protection and capital reserves. Consequently, dividend sustainability is closely tied to underwriting performance and catastrophe exposure.

What Drove Tower’s Strong Financial Recovery?

Tower delivered a strong FY25 performance, highlighting the progress made since its turnaround efforts began.

Gross written premium (GWP) reached approximately NZ$600 million, reflecting continued customer growth and premium increases. Underlying net profit climbed to a record NZ$107.2 million, compared with NZ$83.5 million in the previous year. Reported net profit was NZ$83.7 million.

One of the most impressive achievements was the improvement in the combined operating ratio to 74.1%. This represented a significant enhancement from prior years and indicated exceptionally strong underwriting profitability.

A combined operating ratio at this level means Tower paid out substantially less in claims and expenses than it received in premium income. Such performance reflects disciplined pricing, effective risk management, favorable claims experience, and operational efficiency improvements.

The strong underwriting result provided the foundation for higher shareholder returns and reinforced management's confidence in the business model.

Was the FY25 Dividend Growth Fully Repeatable?

This is arguably the most important question for income investors.

Tower significantly increased shareholder distributions during FY25. Total dividends reached approximately 24.5 cents per share, including a fully imputed final dividend of 16.5 cents per share.

The company also completed a NZ$45 million capital return during 2025, distributing surplus capital to shareholders after strengthening its balance sheet.

While these returns were welcomed by investors, it is important to recognize that not all components are recurring.

Part of the FY25 performance benefited from relatively favorable catastrophe claims experience. In addition, capital returns are typically one-off events rather than regular annual payments. Investors who assume that FY25 distributions represent a new baseline for future income may be disappointed if claims costs normalize or excess capital becomes less available.

The distinction between recurring ordinary dividends and special capital management initiatives is crucial when evaluating long-term dividend sustainability.

How Sustainable Is Tower’s Ordinary Dividend?

The outlook for the ordinary dividend appears considerably stronger than it did several years ago.

Tower's dividend policy targets the distribution of approximately 60% to 80% of cash earnings, a range that provides flexibility while maintaining adequate capital buffers. Based on recent profitability levels, the ordinary dividend appears supported by earnings generation rather than aggressive payout practices.

The company's improved underwriting performance has created a stronger foundation for ongoing distributions. Strong premium growth, disciplined pricing, and operational efficiencies continue to support profitability.

Importantly, Tower remains well capitalized. Regulatory solvency requirements are designed to ensure insurers maintain sufficient financial resources to meet policyholder obligations during periods of elevated claims activity.

Although solvency margins have moderated following recent capital returns, Tower continues to maintain capital levels above regulatory requirements. This provides additional confidence regarding the sustainability of ordinary dividends under normal operating conditions.

However, investors should remember that insurance companies operate in inherently cyclical and unpredictable environments. Sustainability does not mean stability. Earnings and dividends may fluctuate significantly depending on claims experience.

Why Does Catastrophe Risk Matter So Much?

Catastrophe risk remains the single biggest variable affecting Tower's earnings and dividend outlook.

Natural disasters can rapidly transform an insurer’s financial performance. A year with limited catastrophe activity can produce strong profits and generous shareholder returns. Conversely, a major earthquake, severe flooding event, or widespread storm damage can significantly reduce earnings.

To manage this uncertainty, Tower establishes a large-events allowance within its annual planning assumptions. For FY26, the company allocated NZ$45 million for large-event claims.

If actual catastrophe claims remain below this allowance, profitability could remain strong. If claims exceed the allowance, earnings may come under pressure.

This risk is reflected in management guidance. Underlying earnings expectations vary significantly depending on catastrophe experience, highlighting how sensitive insurer profitability remains to external events.

As a result, dividend investors should view Tower differently from sectors with more stable earnings profiles. While dividends can be attractive during favorable years, volatility remains an inherent feature of the insurance industry.

Does Tower Have the Capital Strength to Support Future Dividends?

Capital strength is another important consideration when assessing dividend sustainability.

Tower has spent years strengthening its balance sheet and rebuilding investor confidence. The company now maintains solvency ratios comfortably above regulatory minimums, providing protection against unexpected claims events.

The recent capital return demonstrates management’s willingness to distribute excess capital when appropriate. However, it also means that future special distributions may be less frequent unless profitability continues to expand and excess capital accumulates again.

The balance sheet remains healthy, but investors should not assume that capital returns will occur every year. Management must balance shareholder distributions against regulatory requirements, reinsurance costs, and potential catastrophe exposures.

Therefore, future returns are more likely to be driven by ordinary dividends than repeated large-scale capital management initiatives.

What Is the Bull Case for Tower?

The bullish argument centers on Tower's successful transformation into a more disciplined and profitable insurer.

The company has improved underwriting performance, strengthened its balance sheet, increased profitability, and demonstrated a commitment to shareholder returns. Strong pricing discipline and operational improvements have contributed to one of the strongest combined operating ratios among New Zealand insurers.

Fully imputed dividends add further value for many local investors. If catastrophe activity remains manageable and premium growth continues, Tower could maintain attractive shareholder distributions while generating further earnings growth.

Supporters also argue that management's capital allocation discipline provides additional upside through potential future capital returns when excess solvency capital becomes available.

What Is the Bear Case?

The bear case focuses on the inherently unpredictable nature of insurance earnings.

Tower’s strong FY25 result benefited from favorable conditions that may not persist. Catastrophe losses, reserve movements, and reinsurance costs can all change rapidly.

A major weather event or earthquake could materially reduce profits in a single year, leading to lower dividends despite the company’s strong underlying business.

Investors should also be cautious about anchoring expectations to the unusually high FY25 distribution. A portion of shareholder returns came from one-off capital management actions rather than recurring operating performance.

While the business appears stronger than it was several years ago, insurance remains one of the more volatile sectors for dividend investors.

Dividend Sustainability Rating: Moderately Sustainable

Tower earns a Moderately Sustainable dividend rating. The ordinary dividend is supported by strong underwriting profitability, a disciplined payout policy, improving operational performance, and healthy capital levels. Management has demonstrated a commitment to shareholder returns and has rebuilt the company’s financial position considerably.

However, insurance earnings remain inherently volatile due to catastrophe exposure and claims uncertainty. The exceptional FY25 shareholder return should not automatically be viewed as a recurring annual outcome. While the ordinary dividend appears sustainable under current conditions, future payouts will remain heavily influenced by catastrophe activity and underwriting performance.

Investor Takeaway

Tower has successfully transformed itself from a challenged insurer into a profitable business capable of delivering meaningful shareholder returns. The company’s fully imputed dividends, strong underwriting performance, and improved capital position make it an attractive option for investors seeking exposure to the financial sector.

Nevertheless, investors should focus on the sustainability of the ordinary dividend rather than extrapolating recent capital returns or unusually strong results. Insurance earnings are cyclical, and future payouts will inevitably reflect claims experience and catastrophe activity.

For investors comfortable with insurance-sector volatility, Tower offers a significantly improved dividend profile supported by stronger fundamentals than seen in previous years.
