CPK vs NJR: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CPK and NJR share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CPK and NJR exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Chesapeake Utilities Corporation (NYSE: CPK) delivers energy through two segments. Regulated Energy is the larger one: natural gas distribution in Delaware, Maryland and Florida, electric distribution in northwest Florida through Florida Public Utilities, and interstate and intrastate gas transmission through Eastern Shore Natural Gas and Peninsula Pipeline. Unregulated Energy covers Sharp Energy propane distribution, Aspire Energy gathering and processing in Ohio, and Marlin Gas Services, which trucks compressed natural gas and renewable natural gas to customers off the pipeline grid. The company employs roughly 1,300 people and generated ~$994 million of revenue over the trailing twelve months. Its 2023 purchase of Florida City Gas for ~$923 million roughly doubled the Florida gas footprint and reshaped where growth now comes from.

New Jersey Resources is a diversified energy infrastructure company headquartered in Wall, New Jersey. Its core is New Jersey Natural Gas (NJNG), a regulated utility that distributes gas to roughly 5.6 million people across Monmouth, Ocean, Morris, Middlesex, Sussex and Burlington counties. Around it sit three non-utility segments: Clean Energy Ventures (solar generation), Energy Services (a wholesale natural gas trading and asset-optimization business active across North America), and Storage and Transportation (the Adelphia Gateway pipeline, the Leaf River salt-dome storage facility, and a 50% stake in Steckman Ridge). Company guidance points to the regulated utility contributing roughly 62 to 67 percent of net financial earnings, with the remainder split among Energy Services, Clean Energy Ventures and Storage and Transportation.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• CPK drivers: Florida rate base after Florida City Gas; The Florida Energy Pathway pipeline.
• NJR drivers: Regulated utility rate-base growth; Energy Services trading upside.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The capital program is large relative to the company's size, so financing terms are a live risk: higher interest costs or equity issued at unfavorable prices would dilute the per-share benefit of the same projects. For NJR, as a regulated utility, NJR depends on favorable rate-case outcomes from New Jersey regulators, and unfavorable rulings can compress returns on its heavy capital spending.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick CPK if you believe its drivers more; NJR if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CPK and NJR guides.

CPK. Second-quarter 2026 net income was ~$25.4 million, or ~$1.05 per diluted share, against ~$1.02 a year earlier, with year-to-date EPS of ~$3.51 versus ~$3.22 and adjusted EPS growth of ~8.0%. Adjusted gross margin rose ~$31.2 million, or ~9.6%, through June, driven by transmission projects and regulated infrastructure programs. Analyst consensus for full-year 2026 sits near ~$6.51 per share, and the reaffirmed 2028 range of ~$7.75 to ~$8.00 implies high-single-digit annual growth, which is what the above-peer multiple is priced on.

NJR. NJR trades at a mid-teens multiple of earnings, roughly in line with regulated gas utility peers, reflecting a stable regulated core plus a variable trading component. Management has raised fiscal 2026 net financial earnings guidance twice, largely on strong Energy Services results, so the quality and repeatability of a given year's earnings depends on how much came from the regulated utility versus commodity trading. The roughly 3.3 percent dividend yield and steady dividend growth are central to the total-return story.

Headline figures (approximate, August 2026): CPK shows revenue (ttm) ~$994 million, net income (ttm) ~$150 million, diluted eps (ttm) ~$6.27, p/e (trailing / forward) ~21x / ~19.5x; NJR shows revenue (ttm) ~$2.1B, net income (fy2025) ~$336M, eps (ttm) ~$3.35, market cap ~$4.7B.

CPK and NJR are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
