The Property segment was the standout performer, benefiting from favorable catastrophe reserve development and reduced storm activity:

• Underwriting Income
  : $219.1 million (full year) vs. $167.6 million in 2024
• Combined Ratio
  : 57.2% (full year) vs. 68.5% in 2024
• Q4 Combined Ratio
  : 49.2% (exceptionally strong)
• $17 million of favorable loss emergence on prior years’ catastrophes
• $4 million of storm activity losses in Q4
• Premium declined 11% in Q4 due to intensified competition and increased risk retention by insureds

Management noted that E&S Property premium decreased 18% amid intense competition from carriers and MGAs, with hurricane rates down 15% and earthquake rates declining 12%[0].

The Casualty segment continued to face challenges but showed improvement:

• Underwriting Income
  : $15.9 million (full year) vs. $17.8 million in 2024
• Combined Ratio
  : 98.3% (full year) vs. 97.9% in 2024
• $4 million of favorable prior years’ loss development in Q4
• Transportation premium declined 10% despite 13% rate increases
• Personal Umbrella premium grew 24% with 12% rate increase

The leadership team indicated that while auto-related exposures remain challenging, new claim counts in transportation decreased 24% for the year, suggesting improving trends[0].

1. Strong Underwriting Discipline
   : The 83.6% combined ratio for 2025, combined with 30 consecutive years of underwriting profitability, demonstrates the durability of RLI’s business model even in competitive markets[0].

2. Investment Income Growth
   : Net investment income increased 12% to $159.7 million for the full year, with the portfolio generating a 9.0% total return. The investment team is finding accretive fixed income opportunities with purchase yields averaging 4.9%, approximately 70 basis points above book yield[0].

3. Capital Return to Shareholders
   : The company paid a special dividend of $2.00 per share ($183.7 million) and maintained its 50-year streak of increasing regular dividends. Book value per share grew 33% (inclusive of dividends) to $19.35[0].

4. Favorable Reserve Development
   : $87.4 million in favorable development from prior years’ loss reserves significantly boosted underwriting income, partially offset by $26.5 million in net storm losses[0].

1. Competitive Pricing Environment
   : Management acknowledged intensifying competition across multiple segments. E&S Property is experiencing aggressive pricing from MGAs with misaligned incentives, where capacity providers have “no downside” and seek to deploy capital quickly[0].

2. Reinsurance Cost Dynamics
   : While reinsurance costs decreased 15-20% on the catastrophe program, management noted this benefit may already be factored into pricing, with potential for further softening in spring 2026 when additional capacity renewals occur[0].

3. Casualty Reserve Considerations
   : Despite reserve releases, management remains cautious on auto-related exposures, noting that initial booking ratios tend to hold longer and the company typically waits to confirm positive trends before recognizing improvements[0].

4. Expense Ratio Pressure
   : The expense ratio increased to 39.3% in Q4 from 37.6% a year ago, driven by higher bonus and profit-sharing expenses on strong results and continued investments in people and technology[0].

RLI’s January 1, 2026 reinsurance renewals demonstrated successful execution of its market positioning:

• 15-20% rate decreases
  on catastrophe program (buyer’s market)
• $150 million reduction
  in catastrophe limit while maintaining $50 million attachment point
• 5% rate decreases
  on casualty treaties with some coverage broadening

Management indicated they remain ready to approach the market mid-term should opportunities arise, consistent with prior years’ approach[0].

Line of Business	Rate Environment	Company Response
Personal Umbrella	Competitive but improving	12% rate increase approved (20% in California); additional filings underway
Transportation	Challenging	13% rate increase obtained; targeting double-digit increases in 2026
E&S Property	Softening	Pulling back on unprofitable business; selective retention
E&S Casualty	Competitive on large accounts	Maintaining terms and conditions; 10% full-year premium growth

Management provided granular insights on market competition:

1. E&S Property
   : “Carrier competitors in the E&S Property market slowly giving back terms and conditions while MGAs are being more aggressive.” RLI focuses on accounts where it can achieve target returns rather than competing on price[0].

2. Personal Umbrella
   : “The personal umbrella market continues to present opportunities as our competitors responded to deteriorating results by adjusting their appetite and terms and conditions.” The company benefits from embedded distribution relationships and daily monitoring of submission quality[0].

3. Fourth Quarter Competition
   : “Some people feel it’s worse” but this is largely qualitative assessment. The fourth quarter is always challenging as competitors chase year-end bonus targets based on premium volume[0].

RLI’s ongoing technology investments are designed to enhance underwriting decision-making:

• Customer experience improvements
  : Simplified application processes and automation
• Efficiency gains
  : AI and automation for administrative tasks, claims handling
• Data infrastructure
  : Real-time dashboards linking submission data with loss information by producer, state, and business type

These investments position the company to maintain discipline as the market softens, enabling “granular, real-time decision-making” across the portfolio[0].

CEO Craig Kliethermes summarized the company’s positioning:

“The environment remains competitive, and premium growth was modest, but that’s exactly when our model tends to show its strength. We don’t measure success by how fast we grow. We measure it by how well we grow — and whether today’s decisions stand the test of time.”[0]

CFO Aaron Diefenthaler added on the operating earnings definition change:

“Currently, unconsolidated investees only includes our minority investment in Prime Holdings. We believe excluding these investments from operating earnings better reflects RLI’s core operations, where we maintain full operational control, and aligns the treatment of investee results with other equity investments.”[0]

COO Jennifer Klobnak emphasized the company’s competitive positioning:

“In a more challenging environment, capital discipline and alignment of interests differentiate successful insurers… We are an Underwriting company as evidenced by our unmatched track record of 30 consecutive years of underwriting profit.”[0]

The January 23, 2026 Form 8-K filing reveals that RLI Corp. enters 2026 from a position of substantial strength, with record underwriting income, improved combined ratios, and robust investment returns. The company’s 30-year track record of underwriting profitability provides credibility to its discipline-first approach during a period of market softening.

• Strong reserve position with demonstrated favorable development
• Continued investment income growth with attractive reinvestment rates
• Proven ability to generate capital for shareholder returns
• Technology investments enhancing underwriting decision-making

• Casualty segment reserve development, particularly auto-related lines
• Property rate trajectory as reinsurance savings flow through to pricing
• Personal umbrella competitive dynamics as larger carriers increase focus
• Expense ratio management as investments in technology and talent continue

RLI’s management demonstrated confidence in navigating a softer market cycle, emphasizing that “all we need is a stable market” and that the current catastrophe market is “well priced with reasonable terms and conditions” for disciplined underwriters[0].
