Fast growth, but earthquake pricing is cracking

Q1 2026 gross written premiums rose 42.4% to $629.8 million, with growth in all five product groups.
Management raised 2026 adjusted net income guidance to $262 million to $278 million after another earnings beat.
The biggest pressure point is Commercial Earthquake, where renewal rates fell about 18% in Q1.
Casualty, Crop, Inland Marine, and Surety are now doing more of the growth work as Palomar diversifies.
The stock has a balanced setup: good growth, solid capital tools, but real reserve and weather risks.

01 Running thesis

Diversification is passing its first test

Palomar is still executing its Palomar 2x plan, which aims to roughly double adjusted net income over time by adding more niche insurance lines. Q1 2026 kept that story alive. Gross written premiums grew 42.4%, adjusted net income grew 23.1%, and management raised full-year adjusted net income guidance to $262 million to $278 million.

The bull case is that Palomar is no longer only an earthquake insurer. Casualty, Crop, Inland Marine and Property, and Surety and Credit are growing fast enough to offset pressure in a core line. The company also added a new $200 million share repurchase plan, which can help per-share results if the stock price is attractive.

The bear case is sharper than it was a year ago. Commercial Earthquake renewal rates fell about 18% in Q1, worse than the roughly 15% decline called out in Q4. That is a problem because earthquake has long been a key, high-margin franchise for Palomar.

The other big test is loss development. Casualty grew very fast in 2024 and 2025, and insurance losses can take years to show up. Crop also carries more direct risk in 2026 because Palomar raised net retention to 50%, meaning it keeps more of the profit but also more of the losses.

May 2026→The Q1 2026 10-Q confirmed the earnings release. Gross written premiums were $629.8 million, up 42.4%, with no major thesis change after the call.

May 2026▲Palomar raised 2026 adjusted net income guidance to $262 million to $278 million and announced a $200 million buyback. The positive update was partly offset by Commercial Earthquake renewal rates falling about 18%.

Feb 2026▲Full-year 2025 results beat expectations, and Palomar set strong initial 2026 guidance. The company also reorganized reporting into five product groups and raised Crop net retention to 50%.

Nov 2025▲The Gray Casualty and Surety deal added scale to surety and strengthened the diversification story. Casualty and Crop growth were very strong, but reserve and integration risk moved higher.

May 2025▲Palomar started 2025 with 85% adjusted net income growth and progress in surety and crop integration. Better reinsurance terms helped offset fronting runoff and property market competition.

Aug 2024▲The first thesis framed Palomar as a fast-growing specialty insurer moving beyond earthquake. Early concerns focused on casualty loss development and the loss of a major fronting client.

02 Business model

Small markets, carefully priced risk

Palomar makes money by writing specialty insurance policies. Gross written premium is the total policy premium it writes before sending some risk to reinsurers. Reinsurance is insurance for insurers, and Palomar uses it to cap losses from big events like earthquakes, hurricanes, floods, and droughts.

The company sells through agents, program administrators, wholesale brokers, and insurance partnerships. Its insurance units carry A or A- ratings from AM Best, which matters because brokers and customers often need a highly rated insurer before they place business.

Growth is helped by acquisitions. First Indemnity of America added surety, Advanced AgProtection added crop talent, and Gray Casualty and Surety scaled the surety platform. That makes Palomar less tied to one property cycle, but it also raises integration risk.

The model breaks if pricing weakens faster than loss risk falls, if reserves are too low, or if a major catastrophe hits before reinsurance and capital can absorb the shock. Q1 showed both sides at once: fast premium growth, but a higher combined ratio and more pressure in Commercial Earthquake.

03 Product portfolio

Five specialty lanes

Cash cow

Earthquake

This is Palomar's original franchise, covering residential and commercial earthquake risk. Residential is holding up with strong retention, but Commercial Earthquake is under rate pressure.

Growth engine

Inland Marine and Property

This includes builders risk, excess property, Hawaiian hurricane, and flood. Growth is being helped by builders risk and Hawaiian hurricane, plus a new construction engineering push.

Growth engine

Casualty

This covers niche liability lines, including general liability, contractors, and environmental liability. It is growing fast, but claims can take time to appear, so reserves matter.

Option

Crop

Crop insurance grew quickly after the Advanced AgProtection deal. Palomar raised its 2026 net retention to 50%, which lifts both profit potential and weather risk.

Steady

Surety and Credit

Surety bonds help guarantee that contractors or other parties meet obligations. Gray Surety gives Palomar more scale in a line that should be less tied to earthquake and property cycles.

Mix is based on Q1 2026 gross written premiums from the Form 10-Q. Crop is seasonal, with more written premium usually recognized in the third quarter, so this quarter is not a full-year mix.

05 Risk factors

What could break the thesis

Commercial Earthquake price cuts

High impact · High odds

Commercial Earthquake renewal rates fell about 18% in Q1 2026 after being down about 15% in Q4 2025. If that becomes normal for one to two years, Palomar may have to choose between lower growth and weaker margins in a core business.

We watchCommercial Earthquake renewal rate change and Earthquake gross written premium growth.

Casualty reserves prove too low

High impact · Medium odds

Casualty gross written premiums grew 55% year over year in Q1, after much faster growth in 2025. Liability claims can develop slowly, so a good first year does not prove the book is safe. Palomar says more than 85% of casualty reserves are IBNR, meaning reserves for claims that have happened but are not fully reported yet.

We watchPrior-year reserve development, casualty loss ratio, and management comments on claims severity.

Crop weather hits retained losses

High impact · Medium odds

Palomar is keeping 50% net retention on Crop in 2026. That can improve earnings in a good crop year, but it also makes profits more sensitive to drought and other weather events. Corn and soybean results in the Midwest are the key swing factor.

We watchMidwest drought data, Q2 and Q3 Crop loss ratios, and any change to Crop profit guidance.

Catastrophe shock

High impact · Medium odds

Palomar still writes catastrophe-exposed business, including earthquake, Hawaiian hurricane, flood, and builders risk. Reinsurance reduces the damage, but it does not remove all risk. A major event can hit earnings, capital, and future reinsurance pricing.

We watchLarge insured events in California, Hawaii, and key builders risk markets, plus reinsurance renewal costs.

Acquisition integration slips

Medium impact · Medium odds

Palomar has used deals to add crop and surety scale. Gray Surety is now part of the Surety and Credit segment, and management says integration is going well. The risk is that systems, people, or underwriting controls do not scale as planned.

We watchSurety and Credit growth, expense ratio changes, and any comments on integration costs or lost producers.

06 Quick answers

In one breath

What does Palomar Holdings do?

Palomar is a specialty insurance company. It writes policies in earthquake, property, casualty, crop, and surety markets that larger insurers may not focus on.

Why is Commercial Earthquake important to Palomar?

Earthquake is Palomar's original core franchise. Residential earthquake is still steady, but Commercial Earthquake pricing is under pressure, with renewal rates down about 18% in Q1 2026.

What is the main bull case for PLMR stock?

The bull case is that Palomar can keep growing earnings by diversifying beyond earthquake. Q1 2026 showed broad growth, higher guidance, and a new $200 million buyback plan.

What is the main risk for Palomar?

The main risk is that newer growth lines bring losses that are not yet visible. Casualty reserves, Crop weather losses, and Commercial Earthquake price cuts are the key items to watch.
