Common Stock

We are offering $330,000,000 of shares of our common stock, par value per share $0.4867 (“Common Stock”), pursuant to this prospectus supplement and the accompanying prospectus.

Our Common Stock is listed on the New York Stock Exchange (the “NYSE”) under the symbol “CPK.” The last reported sale price of our Common Stock on the NYSE on November 8, 2023 was $88.07 per share.

On September 26, 2023, we entered into a stock purchase agreement with Florida Power & Light Company (“FPL”) to acquire Pivotal Utility Holdings, Inc., doing business as Florida City Gas (“FCG”), a wholly owned subsidiary of FPL (the “Acquisition”). See “Summary—Acquisition of the FCG Business.”

We expect to use the net proceeds from this offering, together with the net proceeds from an offering of senior notes and borrowings under our existing unsecured revolving credit facility, to finance the Acquisition and to pay related fees and expenses. Completion of this offering is not conditioned upon consummation of the Acquisition. If the Acquisition is not consummated for any reason, the net proceeds from this offering would be available for general corporate purposes until we determine appropriate allocation.

Investing in our Common Stock involves risks. See “Risk Factors” on page S-17 of this prospectus supplement and on page 4 of the accompanying prospectus, and under Part I—Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022, which is incorporated by reference herein, for a discussion of factors you should consider carefully before investing in our Common Stock.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of the securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

RISK FACTORS

Investing in our Common Stock involves risks. You should carefully consider the risk factors described below and in our reports filed from time to time with the SEC, including those described under Part I—Item 1A, “Risk Factors,” in our Annual Report on Form 10-K for the year ended December 31, 2022, which is incorporated by reference into this prospectus supplement. Before making any investment decision, you should carefully consider these risks. These risks could materially affect our business, results of operations or financial condition and affect the value of our Common Stock. In such case, you may lose all or part of your original investment. The risks described below or incorporated by reference herein are not the only risks facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business, results of operation or financial condition. In addition, with respect to forward-looking statements in this prospectus supplement and the documents we incorporate by reference, please see “Cautionary Statement Regarding Forward-Looking Statements” for a discussion of important factors, risks and uncertainties that may cause actual results to differ materially from anticipated results.

Risks Related to the Acquisition

The Acquisition may not close in the anticipated timeframe or at all for a number of reasons.

On September 26, 2023, we signed the Purchase Agreement for the Acquisition. We expect the Acquisition to close in the fourth quarter of 2023, subject to customary closing conditions. However, completion of the Acquisition is not a condition to completion of this offering of Common Stock, and there can be no assurance that the Acquisition will be completed.

There are certain risks and uncertainties relating to the Acquisition. For example, the Acquisition may not be completed, or may not be completed in the time frame, on the terms or in the manner currently anticipated. There can be no assurance that the conditions to closing of the Acquisition will be satisfied or waived or that other events will not intervene to delay or result in the failure to close the Acquisition. In addition, both we and FPL have the ability to terminate the Purchase Agreement under certain circumstances. Failure to complete the Acquisition would prevent us from realizing the anticipated benefits of the Acquisition. We would also remain liable for significant transaction costs, including legal, accounting and financial advisory fees.

In addition, the market price of our Common Stock may reflect various market assumptions as to whether the Acquisition will be completed. Consequently, the completion of, the failure to complete, or any delay in the closing of the Acquisition could result in a significant change in the market price of our Common Stock.

Even if the Acquisition is completed, we may fail to realize the business benefits and growth prospects anticipated as a result of the Acquisition.

The success of the Acquisition will depend, in part, on our ability to successfully integrate the FCG business operations with ours. If we are unable to do so following the Acquisition, the anticipated benefits and potential synergies of the Acquisition may not be realized fully or at all, or may take longer to realize than expected. Integration of FCG may provide more challenging or time consuming than we expect and there are various uncertainties associated with transitioning certain business practices and services following completion of the Acquisition. For example, FCG’s supply arrangements were structured differently than our current practice and we will need to arrange various third-party services that will be transitioned following the completion of the Acquisition. On the other hand, we may not be familiar with certain business practices of FCG that are expected to remain in place, like its outsourced offshore customer service function. Although we believe these challenges are manageable and have plans to finalize the transition in an orderly manner, unforeseen challenges and delays could impact performance. Any failure to timely realize the anticipated benefits of the Acquisition could have a material adverse effect on our business, operating results, and financial condition. Furthermore, FCG may have unknown or contingent liabilities that we would assume in the Acquisition and that were not discovered during the course of our due diligence. These liabilities could include exposure to unexpected asset quality problems,

S-17

compliance and regulatory violations and issues, key employee retention problems, market and customer issues, and other problems that could result in significant costs to us.

All of these factors could cause dilution to our earnings per share, decrease or delay the expected accretive effect of the transaction, negatively impact the price of our Common Stock, or have a material adverse effect on our business, financial condition and results of operations.

The due diligence process that we undertook in connection with the Acquisition may not have revealed all facts that may be relevant in connection with the Acquisition.

In deciding whether to enter into the Purchase Agreement, we conducted the due diligence investigation that we deemed reasonable and appropriate based on the facts and circumstances applicable to the Acquisition. When conducting due diligence, we evaluate important and complex business, financial, tax, accounting, technological, governance, legal and regulatory issues. In addition to our employees, outside consultants, legal advisors and accountants were involved in the due diligence process in varying degrees. Despite our efforts, the results of our due diligence may not be complete and accurate or, even if complete and accurate, may not be sufficient to identify all relevant facts, which could prevent us from realizing the anticipated benefits we expect to achieve as a result of the Acquisition and our business and results of operations could be adversely affected.

The historical financial statements of FCG incorporated by reference herein are not representative of the future financial position, future results of operations or future cash flows of FCG following the Acquisition.

The financial position, results of operations and cash flows of FCG presented in the financial statements incorporated by reference herein may be different from those that would have resulted had FCG been operated as part of our business and different from those that may result in the future from FCG being operated as a part of our business. This is primarily because, among other things:

Accordingly, the historical financial statements of FCG incorporated by reference herein should not be viewed as indicative of the future financial position, future results of operations or future cash flows of FCG following the Acquisition, or as indicative of the financial position, results of operations or cash flows of FCG for any period.

The Acquisition and its announcement may adversely affect the relationships that we and FCG have with our business partners, including with customers and service providers, whether or not the Acquisition is completed.

Parties with whom we or FCG do business may experience uncertainty associated with the Acquisition, including with respect to current or future business relationships with us or FCG. These business relationships may be subject to disruption as customers and others may attempt to (i) negotiate changes in existing business relationships, (ii) delay, defer or cease purchasing services from or providing services to us or FCG or (iii) consider entering into business relationships with parties other than us or FCG, including our competitors or those of FCG. These disruptions could have a material adverse effect on the businesses, operating results, and financial condition of each of us.

S-18

The Acquisition could divert management attention or disrupt our and FCG’s respective businesses, which in either case could adversely affect our future business, operations and financial results following the Acquisition.

Whether or not the Acquisition is completed, the announcement and pendency of the Acquisition could divert management’s attention or disrupt our and FCG’s respective businesses. Both our and FCG’s management have devoted significant attention and resources to the Acquisition and we expect they will need to continue to do so. To the extent this diversion of attention and resources to the Acquisition limits management from continuing to focus on ongoing business operations as they have in the past, both our and FCG’s business could be adversely impacted. We and FCG are both dependent on the experience and industry knowledge of our respective senior management and other key employees to execute our respective business plans. Our success after the Acquisition will depend in part upon our and FCG’s ability to retain our respective key management personnel and other of our respective key employees in advance of and following the Acquisition. Our current and prospective employees and those of FCG may experience uncertainty about their roles within the respective companies following the Acquisition, which may have an adverse effect on the current ability of us and FCG to retain key management and other key personnel. Accordingly, no assurance can be given that we or FCG will be able to retain key management personnel and other key employees before or after the Acquisition. In addition, following the Acquisition, we might not be able to locate suitable replacements for any such key employees who leave us or FCG or offer employment to potential replacements on satisfactory terms.

We will incur significant integration costs in connection with the Acquisition and significant transaction expenses in connection with the consummation of the Acquisition and the related financing transactions, and there may be additional unexpected costs, charges and expenses resulting from the proposed Acquisition.

We are currently developing a plan to integrate the operations of FCG after the completion of the Acquisition. In connection with that plan, we anticipate that we will incur certain non-recurring charges in connection with this integration; however, we cannot identify the timing, nature and amount of all such charges as of the date of this prospectus supplement. Further, we currently expect to incur significant transaction costs relating to completing the Acquisition and the related financing transactions. These integration costs and transaction expenses will be charged as an expense in the period incurred. The significant transaction costs and Acquisition-related integration costs could materially affect our results of operations in the period in which such charges are recorded. Although we believe that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the business will offset incremental transaction and Acquisition-related costs over time, this net benefit may not be achieved in the near term, or at all.

If we successfully acquire FCG, the acquired business may underperform relative to our expectations.

Following completion of the Acquisition, we may not be able to maintain the levels of revenue, earnings or operating efficiency that we and FCG have achieved or might achieve separately. The business and financial performance of FCG are subject to certain risks and uncertainties, including the risk of the loss of, or changes to, its relationships with its customers or changes in rates or other conditions imposed by regulators. We may be unable to achieve the same growth, revenues and profitability that FCG has achieved in the past. The FPSC approved a $23.3 million annual base rate increase for FCG effective May 1, 2023. However, an appeal of certain portions of this decision by Florida Office of Public Counsel to the Florida Supreme Court is pending. To the extent this appeal is successful, and the base rate increase is limited in any way, it could impact our ability to achieve the anticipated benefits of the Acquisition.

The future results of our Company will suffer if we do not effectively manage our expanded operations following the Acquisition.

Following the Acquisition, the size of our business will increase significantly beyond its current size. Our future success depends, in part, upon our ability to manage FCG, which will pose substantial challenges for management, including challenges related to the management and monitoring of new operations and associated

S-19

increased costs and complexity. There can be no assurances that the FCG’s business will be successful or that we will realize the expected benefits currently anticipated from the Acquisition.

Investors will not have any rights to require us to repurchase any Common Stock offered hereby if the Acquisition is not completed, and our management will have broad discretion over the use of the proceeds and may not apply the proceeds in ways that you believe will increase the value of your investment.

This offering is not contingent on completion of the Acquisition. The Acquisition is subject to the satisfaction of a number of conditions that may prevent, delay or otherwise materially adversely affect the completion of the transaction, including conditions outside the control of the parties to the Purchase Agreement. See “Summary –Acquisition of the FCG Business” in this prospectus supplement. Investors will not have any rights to require us to repurchase any Common Stock offered hereby if the Acquisition is not completed. Accordingly, even if the Acquisition is not completed, Common Stock sold in this offering will remain outstanding.

If the Acquisition is not completed, we will be permitted to use the net proceeds of this offering for a broad range of working capital and general corporate purposes, which may or may not include pursuing alternative acquisitions. You may not agree with the manner in which our management chooses to allocate and use the net proceeds from this offering. Moreover, our management may use the net proceeds for corporate purposes that may not increase our profitability or market value.

Risks Related to Ownership of Our Common Stock

Our Common Stock has experienced, and may continue to experience, price volatility, which could result in substantial losses for investors in our Common Stock.

Our Common Stock has at times experienced substantial price volatility as a result of many factors, including the announcement of this Acquisition, the general volatility of stock market prices and volumes, changes in securities analysts’ estimates of our financial performance, variations between our actual and anticipated financial results, fluctuations in order or backlog levels, fluctuations in energy prices, or uncertainty about current global economic conditions. For these reasons, among others, the price of our stock will continue to fluctuate. In addition, if the market for energy or energy distribution and transmission stocks or the stock market in general experiences a loss of investor confidence, the trading price of our Common Stock could decline for reasons unrelated to our business, financial condition or results of operations. If any of the foregoing occurs, it could cause our stock price to fall and may expose us to lawsuits that, even if unsuccessful, could be costly to defend and a distraction to management.

Future sales of our Common Stock could cause the market price for our Common Stock to decline.

We cannot predict the effect, if any, that market sales of shares of our Common Stock or the availability of shares of our Common Stock for sale will have on the market price of our Common Stock prevailing from time to time. Sales of substantial amounts of shares of our Common Stock in the public market, or the perception that those sales will occur, could cause the market price of our Common Stock to decline or be depressed. The shares of Common Stock issued in connection with this offering will be freely tradable without restriction or further registration under the Securities Act. In connection with this offering, we and our directors and executive officers have agreed with the underwriters to a “lock-up,” pursuant to which neither we nor they will sell, hedge or otherwise dispose of any shares without the prior written consent of Barclays Capital, Inc., for 90 days after the date of this prospectus supplement, subject to certain exceptions. See “Underwriting.” Following the expiration of the applicable lock-up period, all these shares of our Common Stock will also be eligible for future sale. In the future, we may also issue our securities if we need to raise capital in connection with capital expenditures or an acquisition(s). The amount of shares of our Common Stock issued in connection with capital expenditures or an acquisition(s) could constitute a material portion of our then-outstanding shares of Common Stock. Any perceived excess in the supply of our shares in the market could negatively impact our share price and any issuance of additional securities in connection with capital investments or acquisitions may result in additional dilution to you.

S-20

USE OF PROCEEDS

We estimate that the net proceeds from this offering, after deducting underwriting discounts and commissions and before estimated offering expenses, will be approximately $         million, or $             million if the underwriters’ option to purchase additional shares is exercised in full.

We expect to use the net proceeds from this offering, together with the net proceeds from the offering of New Notes and borrowings under the Credit Facility, to finance the Acquisition and to pay related fees and expenses. Completion of this offering is not conditioned upon consummation of the Acquisition. If the Acquisition is not consummated for any reason, the net proceeds from this offering would be available for general corporate purposes until we determine appropriate allocation, which may include spending for capital projects or other transactions to optimize our capital structure.

S-21

CAPITALIZATION

The below table sets forth our consolidated cash and cash equivalents and capitalization as of September 30, 2023:

For purposes of this table, we have assumed that the estimated net proceeds of this offering after deducting the underwriting discount and estimated offering expenses will be approximately $         million. See “Use of Proceeds.”

This offering is not contingent upon consummation of the Acquisition, our completion of the offering of the New Notes or on the terms of these transactions. As a result, we cannot assure you that these transactions will be consummated or, if consummated, that they will be consummated on the terms we currently expect.

You should read this table in conjunction with “Summary – Acquisition of the FCG Business,” “Use of Proceeds,” “Unaudited Pro Forma Condensed Financial Information” included as Exhibit 99.3 to our Current Report on Form 8-K filed on November 9, 2023, which is incorporated by reference into this prospectus supplement, and Part II—Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and related notes thereto in our Annual Report on Form 10-K for the year ended December 31, 2022 and Quarterly Report on Form 10-Q for the quarter ended September 30, 2023, which are incorporated by reference into this prospectus supplement.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

FOR NON-U.S. HOLDERS

The following is a summary of the material U.S. federal income tax consequences to certain non-U.S. holders (as defined below) of the acquisition, ownership and disposition of our Common Stock issued pursuant to this offering but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, published rulings and administrative pronouncements of the Internal Revenue Service (the “IRS”), and judicial decisions, all as of the date hereof. These authorities may be changed, possibly retroactively, so as to result in U.S. federal income tax consequences different from those set forth below. No ruling from the IRS has been, or will be, sought with respect to the tax consequences discussed herein, and there can be no assurance that the IRS will not take a position contrary to the tax consequences discussed below or that any position taken by the IRS would not be sustained.

This summary does not address the tax considerations arising under the laws of any non-U.S., state, or local jurisdiction, or under U.S. federal gift and estate tax laws, except to the limited extent set forth below. In addition, this discussion does not address the application of the Medicare contribution tax on net investment income, the alternative minimum tax, or any tax considerations applicable to a non-U.S. holder’s particular circumstances or non-U.S. holders that may be subject to special tax rules, including, without limitation:

In addition, if an entity or arrangement classified as a partnership for U.S. federal income tax purposes holds our Common Stock, the tax treatment of a partner generally will depend on the status of the partner and upon the

activities of the partnership. Accordingly, partnerships that hold our Common Stock, and partners in such partnerships, should consult their tax advisors.

You are urged to consult your tax advisor with respect to the application of the U.S. federal income tax laws to your particular situation, as well as any tax consequences of the acquisition, ownership, and disposition of our Common Stock arising under the U.S. federal estate or gift tax rules, under the laws of any state, local, non-U.S., or other taxing jurisdiction, or under any applicable tax treaty.

S-24

Non-U.S. Holder Defined

For purposes of this discussion, a non-U.S. holder is a holder of our Common Stock that is not an entity or arrangement treated as a partnership for U.S. federal income tax purposes and is not any of the following:

Dividends and Other Distributions

Dividend payments are at the discretion of our Board of Directors and depend on various factors and restrictions. Dividend payments and any other distributions of cash or property on our Common Stock constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed both our current and our accumulated earnings and profits, they will constitute a return of capital and will first reduce a non-U.S. holder’s adjusted tax basis in its Common Stock, but not below zero, and then will be treated as gain from the sale of stock as described below under “—Gain on Disposition of Our Class A Common Stock.”

Except as otherwise described below in the discussions of effectively connected income, backup withholding and FATCA, any dividend paid to a non-U.S. holder generally will be subject to U.S. federal withholding tax either at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an applicable income tax treaty. In order to receive a reduced treaty rate, a non-U.S. holder must provide us with an IRS Form W-8BEN, IRS Form W-8BEN-E, or other appropriate version of IRS Form W-8, including any required attachments and a valid taxpayer identification number, certifying qualification for the reduced rate; additionally, a non-U.S. holder will be required to update such Forms and certifications from time to time as required by law. A non-U.S. holder of shares of our Common Stock eligible for a reduced rate of U.S. withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. If the non-U.S. holder holds the stock through a financial institution or other agent acting on the non-U.S. holder’s behalf, the non-U.S. holder will be required to provide appropriate documentation to the agent, which then will be required to provide certification to us or our paying agent, either directly or through other intermediaries. Non-U.S. holders should consult their tax advisors regarding their entitlement to benefits under an applicable income tax treaty.

Effectively Connected Income

If a non-U.S. holder is engaged in a U.S. trade or business and dividends on, or any gain recognized upon the disposition of, Common Stock, are effectively connected with the conduct of that U.S. trade or business (and, if required by an applicable income tax treaty, the Non-U.S. holder maintains a permanent establishment in the United States to which dividends are attributable), then such non-U.S. holder would be subject to U.S. federal income tax on that dividend or gain on a net (assuming a timely filed tax return) income basis at the regular rates, unless an applicable income tax treaty provides otherwise. In that case, such non-U.S. holder generally would be exempt from the withholding tax discussed above on dividends, although the non-U.S. holder generally would be required to provide a properly executed IRS Form W-8ECI in order to claim such exemption. In addition, if the non-U.S. holder is a corporation, it generally would be subject to a “branch profits tax” at a rate of 30% (or

S-25

an applicable lower treaty rate) on its effectively connected earnings and profits attributable to such dividend or gain (subject to certain adjustments). Non-U.S. holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Gain on Disposition of Our Common Stock

Except as otherwise described below in the discussions of backup withholding and FATCA, a non-U.S. holder generally will not be subject to U.S. federal income tax on any gain realized upon the sale or other taxable disposition of our Common Stock unless:

Generally, a corporation is a USRPHC if the fair market value of its USRPIs equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business (all as determined for United States federal income tax purposes). We believe that we are not currently and will not become a USRPHC for U.S. federal income tax purposes, and the remainder of this discussion assumes this is the case. However, because the determination of whether we are a USRPHC depends on the fair market value of our USRPIs relative to the fair market value of our other business assets, there can be no assurance that we will not become a USRPHC in the future. Even if we become a USRPHC, however, as long as our Common Stock is “regularly traded” (as defined by applicable Treasury Regulations) on an established securities market, such Common Stock will be treated as USRPIs only if a non-U.S. holder actually or constructively holds more than 5% of such regularly traded Common Stock at any time during the shorter of the five-year period preceding the sale or other taxable disposition of, or the holding period for, our Common Stock. No assurance can be provided that our Common Stock will be regularly traded on an established securities market at all times for purposes of the rules described above.

A non-U.S. holder with gain described in the first bullet above will generally be required to pay tax on the net (assuming a timely filed tax return) gain under regular U.S. federal income tax rates (and a corporate non-U.S. holder described in the first bullet above also may be subject to the branch profits tax at a 30% rate (subject to certain adjustments)), unless otherwise provided by an applicable income tax treaty. A non-U.S. holder described in the second bullet above will generally be required to pay a flat 30% tax (or such lower rate specified by an applicable income tax treaty) on the gain, which gain may be offset by U.S. source capital losses for the year (provided the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses). Non-U.S. holders should consult their tax advisors with respect to whether any applicable income tax or other treaties may provide for different rules.

Backup Withholding and Information Reporting

Information returns are required to be filed with the IRS in connection with any distributions on our Common Stock paid to the non-U.S. holder, regardless of whether such distribution constitute dividends or whether any tax was actually withheld. Pursuant to applicable income tax treaties or other agreements, the IRS may make these reports available to tax authorities in the country of residence or the country in which the non-U.S. holder is established, as applicable.

S-26

Payments of dividends or of proceeds on the disposition of stock made to a non-U.S. holder may be subject to backup withholding at a current rate of 24% unless the non-U.S. holder establishes an exemption, for example, by properly certifying non-U.S. status on an IRS Form W-8BEN, IRS Form W-8BEN-E, or otherwise establish an exemption. Notwithstanding the foregoing, backup withholding may apply if either we or the paying agent has actual knowledge, or reason to know, that a non-U.S. holder is a United States person as defined under the Code. In addition, proceeds of the sale or other taxable disposition of our Common Stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a United States person, or the holder otherwise establishes an exemption. Proceeds of a disposition of our Common Stock conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Backup withholding is not an additional tax; rather, the U.S. federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund or credit may generally be obtained from the IRS, provided that the required information is furnished to the IRS in a timely manner.

Additional Withholding Tax on Payments Made to Foreign Accounts

The Foreign Account Tax Compliance Act and the rules and regulations promulgated thereunder (collectively, “FATCA”) generally impose withholding tax at a rate of 30% on dividends on our Common Stock paid to “foreign financial institutions” (as specially defined under these rules), unless such institution enters into an agreement with the U.S. government to withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding the U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or otherwise establishes an exemption. FATCA also generally imposes a U.S. federal withholding tax of 30% on dividends paid to a “non-financial foreign entities” (as specially defined under these rules) unless such entity provides the withholding agent with a certification identifying certain substantial direct and indirect U.S. owners of the entity, certifies that there are none, or otherwise establishes and certifies to an exemption. An intergovernmental agreement between the United States and a non-U.S. holder’s country of tax residence may modify the requirements described in this paragraph. If a dividend payment is both subject to withholding under FATCA and subject to the withholding tax discussed above under “—Distributions,” the withholding under FATCA may be credited against, and therefore reduce, such other withholding tax.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our Common Stock. Until final Treasury Regulations are issued, Taxpayers generally may rely on proposed Treasury Regulations which eliminate FATCA withholding on payments of gross proceeds from the sale or other disposition of stock.

Non-U.S. holders should consult their tax advisors regarding the possible implications of FATCA on their investment in our Common Stock.

Each prospective investor should consult its tax advisor regarding the particular U.S. federal, state, and local, and non-U.S. tax consequences of purchasing, holding, and disposing of our Common Stock, including the consequences of any proposed change in applicable laws.

UNDERWRITING

Barclays Capital Inc., RBC Capital Markets, LLC and Wells Fargo Securities, LLC are acting as representatives of the underwriters and book-running managers of this offering. Under the terms of an underwriting agreement, which will be filed as an exhibit to a Current Report on Form 8-K to be incorporated into the registration statement to which this prospectus supplement and the accompanying prospectus constitute a part, with respect to the shares being offered, each of the underwriters named below has severally agreed to purchase from us the respective number of shares of common stock shown opposite its name below:

The underwriting agreement provides that the underwriters’ obligation to purchase shares of common stock depends on the satisfaction of the certain conditions contained in the underwriting agreement including:

Commissions and Expenses

The following table summarizes the underwriting discounts and commissions we will pay to the underwriters. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares. The underwriting fee is the difference between the initial price to the public and the amount the underwriters pay to us for the shares.

The representatives have advised us that the underwriters propose to offer the shares of common stock directly to the public at the offering price on the cover of this prospectus supplement and to selected dealers, which may include the underwriters, at such offering price less a selling concession not in excess of $                 per share. If all the shares are not sold at the initial offering price following the initial offering, the representatives may change the offering price and other selling terms.

The expenses of the offering that are payable by us are estimated to be approximately $                (excluding underwriting discounts and commissions).

Option to Purchase Additional Shares

We have granted the underwriters an option exercisable for 30 days after the date of this prospectus supplement to purchase, from time to time, in whole or in part, up to an aggregate of                shares from us at the public offering price less underwriting discounts and commissions. To the extent that this option is exercised,

S-28

each underwriter will be obligated, subject to certain conditions, to purchase its pro rata portion of these additional shares based on the underwriter’s percentage underwriting commitment in this offering as indicated in the above table.

Lock-Up Agreements

We and all of our directors and executive officers have agreed that, for a period of 90 days after the date of this prospectus supplement subject to certain limited exceptions as described below, we and they will not directly or indirectly, without the prior written consent of Barclays Capital Inc., on behalf of the underwriters, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of common stock (including, without limitation, shares of common stock that may be deemed to be beneficially owned by us or them in accordance with the rules and regulations of the SEC and shares of common stock that may be issued upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for common stock (other than the stock and shares issued pursuant to employee benefit plans, qualified stock option plans, or other employee compensation plans existing on the date of this prospectus supplement or pursuant to currently outstanding options, warrants or rights not issued under one of those plans and other than by us pursuant to our existing Dividend Reinvestment and Direct Stock Purchase Plan (including, pursuant to the waiver provisions thereof, up to an additional amount not to exceed $5,000,000 per month)), or sell or grant options, rights or warrants with respect to any shares of common stock or securities convertible into or exchangeable for common stock (other than the grant of options pursuant to option plans existing on this prospectus supplement), (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of shares of common stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of common stock or other securities, in cash or otherwise, (3) make any demand for or exercise any right or file or cause a registration statement to be filed, including any amendments thereto, with respect to the registration of any shares of common stock or securities convertible, exercisable or exchangeable into common stock or any of our other securities (other than any registration statement on Form S-8), or (4) publicly disclose the intention to do any of the foregoing.

The restrictions above do not apply to: (a) transactions relating to shares of common stock or other securities acquired in the open market after the completion of this offering, (b) bona fide gifts, sales or other dispositions of shares of any class of our capital stock, in each case that are made exclusively between and among a stockholder or members of a stockholder’s family, or affiliates of a stockholder, including its partners (if a partnership) or members (if a limited liability company); provided that it shall be a condition to any transfer pursuant to this clause (b) that (i) the transferee/donee agrees to be bound by the terms of the lock-up agreement to the same extent as if the transferee/donee were a party thereto, (ii) each party (donor, donee, transferor or transferee) shall not make any filing or public announcement of the transfer or disposition earlier than required by law prior to the expiration of the 90-day period referred to above, and (iii) the stockholder notifies Barclays Capital Inc. at least two business days prior to the proposed transfer or disposition, (c) the exercise of warrants or the exercise of stock options or the settlement of rights granted pursuant to our stock option/incentive plans or otherwise outstanding on the date of this prospectus supplement; provided, that the restrictions shall apply to shares of common stock issued upon such exercise or conversion or settlement, (d) the establishment of any contract, instruction or plan that satisfies all of the requirements of Rule 10b5-1 (a “Rule 10b5-1 Plan”) under the Exchange Act; provided, however, that no sales of common stock or securities convertible into, or exchangeable or exercisable for, common stock, shall be made pursuant to a Rule 10b5-1 Plan prior to the expiration of the lock-up period (as the same may be extended pursuant to the provisions hereof); provided further, that we do not report the establishment of such Rule 10b5-1 Plan in any public report or filing with the SEC under the Exchange Act earlier than as required, and (e) any demands or requests for, exercises of any right with respect to, or taking of any action in preparation of, the registration by us under the Securities Act of a stockholder’s shares of common stock, provided that no transfer of the stockholder’s shares of common stock registered pursuant to the

S-29

exercise of any such right and no registration statement shall be filed under the Securities Act with respect to any of the stockholder’s shares of common stock during the lock-up period.

When determining whether or not to release common stock and other securities from lock-up agreements, Barclays Capital Inc. will consider, among other factors, the holder’s reasons for requesting the release, the number of shares of common stock and other securities for which the release is being requested and market conditions at the time.

Indemnification

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the underwriters may be required to make for these liabilities.

Stabilization, Short Positions and Penalty Bids

The representatives may engage in stabilizing transactions, short sales and purchases to cover positions created by short sales, and penalty bids or purchases for the purpose of pegging, fixing or maintaining the price of the common stock, in accordance with Regulation M under the Exchange Act:

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of the common stock. As a result, the price of the common stock may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the NYSE or otherwise and, if commenced, may be discontinued at any time.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the common stock. In

S-30

addition, neither we nor any of the underwriters make any representation that the representatives will engage in these stabilizing transactions or that any transaction, once commenced, will not be discontinued without notice.

Electronic Distribution

A prospectus in electronic format may be made available on the Internet sites or through other online services maintained by one or more of the underwriters and/or selling group members participating in this offering, or by their affiliates. In those cases, prospective investors may view offering terms online and, depending upon the particular underwriter or selling group member, prospective investors may be allowed to place orders online. The underwriters may agree with us to allocate a specific number of shares for sale to online brokerage account holders. Any such allocation for online distributions will be made by the representatives on the same basis as other allocations.

Other than the prospectus in electronic format, the information on any underwriter’s or selling group member’s web site and any information contained in any other web site maintained by an underwriter or selling group member is not part of the prospectus or the registration statement of which this prospectus forms a part, has not been approved and/or endorsed by us or any underwriter or selling group member in its capacity as underwriter or selling group member and should not be relied upon by investors.

Listing on the NYSE

Our common stock is listed on the NYSE under the symbol “CPK.”

Stamp Taxes

If you purchase shares of common stock offered in this prospectus supplement, you may be required to pay stamp taxes and other charges under the laws and practices of the country of purchase, in addition to the offering price listed on the cover page of this prospectus supplement.

Other Relationships

Affiliates of RBC Capital Markets, LLC and Wells Fargo Securities, LLC are lenders under our Credit Facility, and, if the Acquisition is not consummated and the net proceeds of this offering are used for general corporate purposes, may receive a portion of the net proceeds from the sale of shares of our common stock if we use such proceeds to repay borrowings thereunder. Because of these relationships, RBC Capital Markets, LLC and Wells Fargo Securities, LLC are deemed to have a “conflict of interest” under Rule 5121 of the Financial Industry Regulatory Authority (“FINRA”). Accordingly, this offering is being conducted in accordance with the applicable provisions of FINRA Rule 5121. See “Use of Proceeds.”

On September 26, 2023, we entered into the commitment letter providing for the Bridge Facility in an aggregate initial principal amount of $965 million, subject to a number of customary closing conditions. The amounts available under the commitment will be reduced by, among other things, the net proceeds we receive in the offering of the New Notes, amounts borrowed under the Credit Facility, and this offering. Certain of the underwriters in this offering or their affiliates, including affiliates of Barclays Capital Inc. RBC Capital Markets, LLC and Wells Fargo Securities, LLC, are participating lenders.

In addition, certain of the underwriters of this offering or their affiliates, including Barclays Capital Inc. RBC Capital Markets, LLC and Wells Fargo Securities, LLC, are serving as placement agents in connection with our offering of New Notes.

The underwriters and certain of their affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory,

S-31

investment management, investment research, principal investment, hedging, financing and brokerage activities. The underwriters and certain of their affiliates have, from time to time, performed, and may in the future perform, various commercial and investment banking and financial advisory services for the issuer and its affiliates, for which they received or may in the future receive customary fees and expenses.

In the ordinary course of their various business activities, the underwriters and certain of their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of the issuer or its affiliates. If the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, the underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities or the securities of our affiliates, including potentially the shares of common stock offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the shares of common stock offered hereby. The underwriters and certain of their affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

This prospectus and the applicable prospectus supplements include and incorporate by reference forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the Private Securities Litigation Reform Act of 1995. One can typically identify forward-looking statements by the use of forward-looking words, such as “project,” “believe,” “expect,” “anticipate,” “intend,” “plan,” “estimate,” “continue,” “potential,” “forecast” or other similar words, or future or conditional verbs such as “may,” “will,” “should,” “would” or “could.” These statements represent our intentions, plans, expectations, assumptions and beliefs about future financial performance, business strategy, projected plans and objectives of the Company. Forward-looking statements speak only as of the date they are made or as of the date indicated and we do not undertake any obligation to update forward-looking statements as a result of new information, future events or otherwise.

THE COMPANY

Chesapeake Utilities is a Delaware corporation formed in 1947 with operations primarily in the Mid-Atlantic region, North Carolina, South Carolina, Florida and Ohio. We are an energy delivery company engaged in the distribution of natural gas, electricity and propane; the transmission of natural gas; the generation of electricity and steam, and in providing related services to our customers. Our strategy is focused on growing earnings from a stable regulated energy delivery foundation and investing in related businesses and services that provide opportunities for returns greater than traditional utility returns. We seek to identify and develop opportunities across the energy value chain, with emphasis on midstream and downstream investments that are accretive to earnings per share, consistent with our long-term growth strategy and create opportunities to continue our record of top tier returns on equity relative to our peer group. The Company’s growth strategy includes the continued investment and expansion of the Company’s regulated operations that provide a stable base of earnings, as well as investments in other related non-regulated businesses and services including sustainable energy initiatives. By investing in these related business and services, the Company creates opportunities to sustain its track record of higher returns, as compared to a traditional utility company.

We operate within two reportable segments: Regulated Energy and Unregulated Energy. The Regulated Energy segment includes our natural gas transmission, natural gas distribution, and electric distribution operations. All operations in this segment are regulated, as to their rates and service, by the Public Service Commission having jurisdiction in each state in which we operate or by the Federal Energy Regulatory Commission in the case of Eastern Shore Natural Gas Company, our wholly-owned natural gas transmission subsidiary. The Unregulated Energy segment includes natural gas transmission, electricity and steam generation, propane distribution, mobile natural gas utility and pipeline solutions and sustainable energy projects.

The remainder of our operations is presented as “Other businesses and eliminations,” which consists of unregulated subsidiaries that own real estate leased to Chesapeake Utilities, as well as certain corporate costs not allocated to other operations.

Our principal executive office is located at 500 Energy Lane, Dover, Delaware 19901, and our telephone number is (302) 734-6799. Our website address is http://www.chpk.com. Information on our website does not constitute part of this prospectus.

RISK FACTORS

ones we face. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. Our business, financial condition, or results of operations could be materially adversely affected by the materialization of any of these risks. The trading price of our securities could decline due to the materialization of any of these risks and you may lose all or part of your investment. This prospectus and the documents incorporated herein by reference also contain forward-looking statements that involve risks and uncertainties. Actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks described in the documents incorporated herein by reference, which include (i) our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, (ii) our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2023 and June 30, 2023 and (iii) documents we file with the SEC after the date of this prospectus that are incorporated by reference into this prospectus.

Shares of preferred stock may be issued by us from time to time, by authorization of the Board of Directors and without the necessity of further action or authorization by our stockholders, in one or more series and with such voting powers, designations, preferences and relative, participating, optional, or other special rights and qualifications as the Board of Directors may, in its discretion, determine, including, but not limited to: (a) the distinctive designation of such series and the number of shares to constitute such series; (b) the dividend rights, if any, for such series; (c) the voting power, if any, of shares of such series; (d) the terms and conditions (including price), if any, upon which shares of such stock may be converted into or exchanged for shares of stock of any other class or any other series of the same class or any other securities or assets; (e) our right, if any, to redeem shares of such series and the terms and conditions of such redemption; (f) the retirement or sinking fund provisions, if any, of shares of such series and the terms and provisions relative to the operation thereof; (g) the amount, if any, that the stockholders of such series shall be entitled to receive in case of a liquidation, dissolution, or winding up of Chesapeake Utilities; (h) the limitations and restrictions, if any, upon the payment of dividends or the making of other distributions on, and upon the purchase, redemption, or other acquisition by

Certificate of Incorporation Provisions Relating to a Change in Control

Under our Certificate of Incorporation, the affirmative vote of not less than 75% of the total voting power of all outstanding shares of our capital stock is required to approve a merger or consolidation of Chesapeake Utilities with, or the sale of substantially all of our assets or business to, any other corporation (other than a corporation 50% or more of the common stock of which is owned by us), if such corporation or its affiliates singly or in the aggregate own or control directly or indirectly 5% or more of the outstanding shares of our Common Stock, unless the transaction is approved by our Board of Directors prior to the acquisition by such corporation or its affiliates of ownership or control of 5% or more of the outstanding shares of common stock. In addition, our Certificate of Incorporation provides for a classified Board of Directors under which approximately one-third of the members are elected annually for three-year terms. The supermajority voting requirement for certain mergers and consolidations and the classified Board of Directors may have the effect of delaying, deferring, or preventing a change in control of us.

Delaware Anti-Takeover Statute

We are subject to Section 203 of the Delaware General Corporation Law, which, subject to certain exceptions, prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that such stockholder became an interested stockholder, unless: (i) the corporation’s board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder, (ii) upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, or (iii) the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders by the affirmative vote of the stockholders of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

PLAN OF DISTRIBUTION

We may sell the securities offered pursuant to any applicable prospectus supplement as follows:

The name of any underwriter or agent involved in the offer and sale of such securities will be included in the applicable prospectus supplement.

We, directly or through agents or dealers, may sell, and the underwriters may resell, the securities in one or more transactions, including:

6

The distribution of securities offered pursuant to any applicable prospectus supplement may occur:

We may designate underwriters or agents to solicit purchases of shares of our common stock for the period of their appointment and to sell securities on a continuing basis, including pursuant to “at-the-market offerings.” We will do so pursuant to the terms of a distribution agreement between us and the underwriters or agents. If we engage in at-the-market sales pursuant to a distribution agreement, we will issue and sell the shares to or through one or more underwriters or agents, which may act on an agency basis or on a principal basis. During the term of any such distribution agreement, we may sell shares on a daily basis in exchange transactions or otherwise as we agree with the underwriters or agents. The distribution agreement may provide that any shares of our common stock sold will be sold at prices related to the then prevailing market prices for our securities. Therefore, exact figures regarding net proceeds to us or commissions to be paid are impossible to determine and will be described in the applicable prospectus supplement. The terms of each such distribution agreement will be set forth in more detail in a prospectus supplement to this prospectus. To the extent that any named underwriter or agent acts as principal pursuant to the terms of a distribution agreement, or if we offer to sell shares of our common stock through another broker dealer acting as underwriter, then such named underwriter may engage in certain transactions that stabilize, maintain or otherwise affect the price of our shares. We will describe any such activities in the applicable prospectus supplement relating to the transaction. To the extent that any named broker dealer or agent acts as agent on a best efforts basis pursuant to the terms of a distribution agreement, such broker dealer or agent will not engage in any such stabilization transactions.

Agents designated by us from time to time may solicit offers to purchase the securities. We will name any such agent involved in the offer or sale of the securities and set forth any commissions payable by us to such agent in the applicable prospectus supplement relating to any such offer and sale of securities. Unless otherwise indicated in the applicable prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment. Any such agent may be deemed to be an underwriter of the securities, as that term is defined in the Securities Act.

If underwriters are used in the sale of securities, securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions. Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. If an underwriter or underwriters are used in the sale of securities, we will execute an underwriting agreement with such underwriter or underwriters at the time an agreement for such sale is reached. We will set forth in the applicable prospectus supplement the names of the specific managing underwriter or underwriters, as well as any other underwriters, and the terms of the transactions, including compensation of the underwriters and dealers. Such compensation may be in the form of discounts, concessions, or commissions. Underwriters and others participating in any offering of securities may engage in transactions that stabilize, maintain, or otherwise affect the price of such securities. We will describe any such activities in the applicable prospectus supplement. During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The

7

underwriters also may impose a penalty bid, which means that selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if the offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain, or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, the underwriters may discontinue these activities at any time.

If a dealer is used in the sale of the securities, we or an underwriter will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale. The prospectus supplement will set forth the name of the dealer and the terms of the transactions.

We may directly solicit offers to purchase the securities, and we may sell directly to institutional investors or others. These persons may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale of the securities. The applicable prospectus supplement will describe the terms of any such sales, including the terms of any bidding, auction, or other process, if used.

Agents, underwriters, and dealers may be entitled under agreements which may be entered into with us to indemnification by us against specified liabilities, including liabilities under the Securities Act, or to contribution by us to payments they may be required to make in respect of such liabilities. The applicable prospectus supplement will describe the terms and conditions of such indemnification or contribution. Some of the agents, underwriters, or dealers, or their affiliates, may engage in transactions with or perform services for us and our subsidiaries in the ordinary course of their business.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of common shares, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of common shares. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be identified in the applicable prospectus supplement or a post-effective amendment to this registration statement.

If indicated in the applicable prospectus supplement, we may authorize dealers acting as our agents to solicit offers by certain institutions to purchase the securities from us at the public offering price set forth in such prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on the date or dates stated in the prospectus supplement. Each delayed delivery contract will be for an amount not less than the respective amounts stated in the applicable prospectus supplement. Likewise, the aggregate principal amount of the securities sold pursuant to delayed delivery contracts will not be less or more than the respective amounts stated in the applicable prospectus supplement. We may make delayed delivery contracts with various institutions, including commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions, and other institutions. Delayed delivery contracts will always be subject to our approval. Delayed delivery contracts will not be subject to any conditions except the following:

8

Certain of the underwriters or their affiliates may, but will not necessarily, be customers of, engage in transactions with or perform services for us or one or more of our subsidiaries in the ordinary course of our and/or their business. It is also possible that certain of the underwriters or their affiliates may be affiliates of banking institutions or other financial services firms with which we or one or more of our subsidiaries has a pre-existing business relationship.
