Growth plan waits on Florida regulators

01 Running thesis

Good growth, hard timing

CPK is a small utility trying to grow faster than a typical utility. The simple bull case is that it serves places where people and businesses are still being added, mainly Florida and Delmarva. More customers and more pipes can support steady earnings growth if regulators let the company earn a fair return on that spending.

Management has kept its long-term goal of 8% annual EPS growth through 2028. It also kept its 2028 EPS guide of $7.75 to $8.00, even after the WRU LNG storage project slipped. That matters because the delay is real: management expects about a $0.10 hit to 2026 EPS before the project contributes fully in 2027.

The biggest near-term test is Florida City Gas, or FCG. CPK filed for a $47 million base rate increase and asked for an 11.25% return on equity, which is the profit rate regulators allow on shareholder-funded utility investment. A good result would support the deal logic behind buying FCG. A weak result would raise a fair question: did CPK pay too much, or assume too much regulatory help?

The stock does not get a free pass. Finn's overall score is modest, and financial health is the weakest area. That fits a business that can grow, but needs large capital spending and friendly regulators at the same time.

May 2026→CPK filed the FCG rate case, asking for a $47 million base rate increase and an 11.25% ROE. The WRU LNG delay added about a $0.10 expected 2026 EPS headwind, but management kept its 8% long-term EPS growth target and 2028 EPS guide.
Feb 2026▼The Florida City Gas depreciation study ended worse than management hoped, contributing to a 2025 EPS guidance miss. The main focus shifted to the broader FCG general rate case.
Nov 2025▼Q3 2025 EPS of $0.82 missed the $0.90 consensus estimate. With no clear explanation in the available update, near-term execution risk increased.
Aug 2025▲The initial thesis framed CPK as a growth utility with strong regulated gas performance, rising capital spending, and added help from Marlin and RNG. The key risk was the pending Florida regulatory decision tied to FCG.
02 Business model

Pipes, rates, and fuel delivery

The regulated business is the core. CPK distributes and transmits natural gas to homes, businesses, and industrial customers in Florida and the Delmarva Peninsula. It also owns a small electric distribution utility in Florida. In this part of the company, CPK spends money on infrastructure, then asks regulators to let it recover those costs through customer rates.

Growth comes from new customers, new developments, and programs such as GUARD and SAFE that support system upgrades. The catch is timing. A pipe can be built before the company fully earns on it, and rate cases can approve less than management asks for.

The unregulated side adds more market exposure. Sharp Energy sells propane. Marlin Gas Services moves compressed natural gas, liquefied natural gas, and renewable natural gas by truck, often called a virtual pipeline. Full Circle Dairy adds renewable natural gas, or RNG, which can earn credits but still has unquantified 2026 benefits from new Production Tax Credits.

This mix can help earnings, but it also adds moving parts. Propane margins can fall. LNG projects can slip. RNG credits can be hard to forecast. For CPK, the model works best when regulated growth covers the base and the unregulated assets add upside without creating big surprises.

03 Product portfolio

What CPK sells

Growth engine

Regulated natural gas distribution

This is the main business. CPK connects homes and businesses to gas service in Florida and Delmarva, then earns through regulated customer rates.

Growth engine

Natural gas transmission

Transmission projects move gas across larger systems. New capacity can add steady margin when regulators approve recovery and customers need the supply.

Steady

Florida electric distribution

CPK owns a small electric utility in Florida. It is not the main growth driver, but it adds another regulated earnings stream.

Cash cow

Propane through Sharp Energy

Sharp Energy sells and distributes propane. It can generate cash, but margins can move with weather, supply costs, and local competition.

Growth engine

Marlin virtual pipeline

Marlin moves CNG, LNG, and RNG by truck for customers that need gas without a normal pipeline connection. Recent growth has come from higher demand for these transportation services.

Option

Renewable natural gas

Full Circle Dairy gives CPK exposure to RNG. The open question is how much new Production Tax Credits will help 2026 earnings.

Option

LNG storage and power infrastructure

WRU LNG storage and other LNG or data-center-linked opportunities could add growth. The WRU delay shows that construction timing can matter a lot.

04 Business segments

Gross margin mix

Regulated Energy83%modest
Unregulated Energy17%modest

Segment shares use Q2 2025 adjusted gross margin disclosed in the company update: about $118 million from Regulated Energy and about $25 million from Unregulated Energy. That mix is based on adjusted gross margin, not revenue.

05 Risk factors

What could break the plan

FCG rate case disappointment

High impact · Medium odds

The Florida City Gas case is the biggest swing factor. CPK asked for a $47 million base rate increase and an 11.25% ROE, plus $16 million in interim rates. If regulators approve much less, the FCG acquisition could earn below plan and pressure the 2028 EPS target.

We watchFlorida Public Service Commission decision on interim rates, then the final approved ROE and base rate increase.

WRU LNG delay gets worse

Medium impact · Medium odds

Management already expects the WRU LNG storage delay to reduce 2026 EPS by about $0.10. The project is still expected to contribute fully in 2027. A further slip would add another earnings gap and weaken confidence in execution.

We watchManagement updates on WRU construction progress and the early 2027 in-service target.

Capital plan strains the balance sheet

High impact · Medium odds

CPK plans $450 million to $500 million of capital spending in 2026 after investing $470 million in 2025. That spending can drive growth, but it also needs funding. Finn's weak financial health score points to this risk.

We watch2026 capital spending updates, debt issuance, equity funding needs, and credit metric commentary.

Unregulated margin softness

Medium impact · Medium odds

The unregulated segment grew in Q2 2025, helped by Marlin and Full Circle Dairy. But propane margins were a partial offset. If propane weakens or mobile gas demand slows, the segment may not provide the extra earnings support management needs.

We watchQuarterly Unregulated Energy adjusted gross margin and management comments on propane margins and Marlin demand.

Unclear RNG and ERP benefits

Low impact · Medium odds

Management has not quantified the 2026 benefit from new Production Tax Credits for RNG assets. It also has not given clear savings targets for Project 1CORE, the enterprise resource planning system. These may help, but investors do not yet have hard numbers.

We watchAny quantified 2026 RNG tax credit benefit or Project 1CORE savings target.
06 Quick answers

In one breath

Is Chesapeake Utilities mainly a gas utility?

Yes. The largest piece is regulated natural gas distribution and transmission in Florida and Delmarva. It also owns a small Florida electric utility and unregulated propane, mobile gas, and RNG businesses.

Why does the Florida City Gas rate case matter so much?

FCG is a major part of the growth plan after CPK bought the business. The company is asking for a $47 million base rate increase and an 11.25% ROE, so the final ruling will shape how much profit CPK can earn on that investment.

What is the WRU LNG issue?

WRU is an LNG storage project that has been delayed. Management expects the delay to reduce 2026 EPS by about $0.10, with full contribution now expected in 2027.

Why is Finn cautious despite the growth target?

The growth plan is real, but it depends on rate case wins, project timing, and heavy capital spending. That mix explains why the overall score is modest and financial health is weak.
