Our Business

Chesapeake Utilities Corporation is a Delaware corporation formed in 1947. We are a diversified energy company engaged, through our operating divisions and subsidiaries, in various energy and other businesses. We operate primarily on the Delmarva Peninsula and in Florida, Pennsylvania and Ohio, largely providing natural gas distribution and transmission, natural gas supply, gathering and processing, electric distribution and propane distribution service. The core of our business is regulated energy services, which provides stable earnings through our utility operations. Our unregulated businesses provide opportunities to achieve returns greater than those of a traditional utility. The following charts present operating income by type of energy served and geographic area for the year ended December 31, 2015 and average investment by type of energy served and geographic area as of December 31, 2015.

S-1

Operating Income by Energy Served and Geographic Area

Average Investment by Energy Served and Geographic Area

We operate within two reportable segments: Regulated Energy and Unregulated Energy. The Regulated Energy segment includes our natural gas distribution, natural gas transmission and electric distribution operations. All operations in this segment are regulated, as to their rates and service, by the public service commission (“PSC”) having jurisdiction in each state in which we operate or by the Federal Energy Regulatory Commission (“FERC”) in the case of Eastern Shore Natural Gas Company (“Eastern Shore”). The Unregulated Energy segment includes our propane distribution, propane wholesale marketing, natural gas marketing and natural gas supply, gathering and processing services, which are unregulated as to their rates and services. Also included in this segment are other unregulated energy services, such as energy-related merchandise sales; heating, ventilation, and air conditioning, plumbing, and electrical services; and electricity and steam generation services from the combined heat and power (“CHP”) plant we recently placed into service in Amelia Island, Florida.

S-2

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.

Regulated Energy

Regulated Energy is our largest segment and consists of: (i) our natural gas distribution operations in Delaware, Maryland and Florida; (ii) our electric distribution operation in Florida; and (iii) our natural gas transmission operations on the Delmarva Peninsula and in Florida. Our natural gas and electric distribution operations, which are local distribution utilities, generate revenues based on tariff rates approved by the PSC of each state in which we operate. The PSCs have also authorized our utilities to negotiate rates, based on approved methodologies, with customers that have competitive alternatives. Some of our customers in Maryland are currently served with propane under PSC-approved tariff rates as we prepare to convert some of our underground propane distribution system customers to natural gas. These customers are included in the Delmarva natural gas distribution operation.

Eastern Shore, our interstate natural gas transmission subsidiary, bills its customers based upon FERC-approved tariff rates. Eastern Shore is also authorized by FERC to negotiate rates above or below FERC-approved tariff rates. Peninsula Pipeline, our Florida intrastate pipeline subsidiary, is subject to regulation by the Florida PSC, and has negotiated contracts with third-party customers and with certain affiliates. Our rates are designed to provide the opportunity to generate revenues to recover all prudently incurred costs and provide a return on rate base sufficient to pay interest on debt and a reasonable return for our stockholders. Rate base generally consists of the original cost of utility plant less accumulated depreciation on utility plant in service, working capital and certain other assets and, depending upon the particular regulatory jurisdiction, may also include deferred income tax liabilities and other additions or deletions.

The natural gas commodity market for Chesapeake Utilities’ Florida division and FPU’s Indiantown division is deregulated. Accordingly, marketers, rather than a traditional utility, sell natural gas to end-use customers in those jurisdictions. For all of our other local distribution utilities, we have fuel cost recovery mechanisms authorized by the PSCs that allow us to periodically adjust fuel rates to reflect changes in the wholesale cost of natural gas and electricity and to ensure we recover all of the costs prudently incurred in purchasing natural gas and electricity for our customers.

Unregulated Energy

Our Unregulated Energy segment provides propane distribution, propane wholesale marketing, natural gas marketing, supply, gathering and processing and other unregulated energy-related services to customers. Revenues generated from this segment are not subject to any federal, state or local pricing regulations. Our businesses in this segment typically complement our regulated businesses by offering propane as a fuel source where natural gas is not readily available, or by providing natural gas marketing, supply, gathering and processing services to our customers. Through competitive pricing and supply management, these businesses provide the opportunity to generate returns greater than those of a traditional utility.

Our propane distribution operations sell propane primarily to residential, commercial/industrial and wholesale customers in Delaware, Maryland, Virginia and in southeastern Pennsylvania through Sharp and Sharpgas, and in Florida through FPU and Flo-gas. Many of our propane distribution customers are “bulk delivery” customers. We make deliveries of propane to the bulk delivery customers as needed, based on the level of propane remaining in the tank located at the customer’s premises. We invoice and record revenues for our bulk delivery service customers at the time of delivery, rather than upon customers’ actual usage, since the customers typically own the propane gas in the tanks on their premises. We also have underground propane distribution systems serving various neighborhoods and communities. Such customers are billed

S-3

monthly based on actual consumption, which is measured by meters installed on their premises. In Florida, we also offer metered propane distribution service to residential and commercial customers. The customers’ tanks are metered, and we read and bill the customers once a month.

Other Businesses

Other businesses consists primarily of other unregulated subsidiaries, including Skipjack and ESRE that own real estate leased to affiliates; and certain unallocated corporate costs, which are not directly attributable to a specific business unit. Skipjack and ESRE own and lease office buildings in Delaware and Maryland to divisions and other subsidiaries of Chesapeake Utilities.

Recent Developments

In June 2016, we commenced operations of our first CHP plant in Amelia Island, Florida, through our newest subsidiary, Eight Flags Energy. We anticipate that the CHP plant will yield significant cost-savings for customers on Amelia Island, while also providing environmental benefits, such as reduced greenhouse gas emissions and lower water use than conventional utility power plants.

Corporate Information

Our principal executive office is located at 909 Silver Lake Boulevard, Dover, Delaware 19904, 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

An investment in our common stock involves risks. You should read carefully the risks and uncertainties described below and the “Risk Factors” section in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, which is incorporated by reference into this prospectus supplement and the accompanying prospectus, in addition to the other information set forth or incorporated by reference in this prospectus supplement and the accompanying prospectus, before making an investment an investment decision. Also, these risks are not the only 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.

Risks relating to the Company’s Common Stock

The market price of the Company’s common stock may fluctuate significantly, which could negatively affect the Company and holders of its common stock. Such fluctuations in price may occur from time to time as a result of many factors, including but not limited to:

•

investors’ perceptions of the prospects of the Company and the energy and commodities markets;

•

investors’ perceptions of the Company’s and/or the industry’s risk and return characteristics relative to other investment alternatives;

•

differences between our actual financial and operating results and those expected by investors and analysts;

•

changes in analyst reports, recommendations or earnings estimates regarding the Company, other comparable companies or the industry generally, and the Company’s ability to meet those estimates;

•

actual or anticipated fluctuations in quarterly financial and operating results;

•

volatility in the equity securities market; and

•

sales, or anticipated sales, of large blocks of the Company’s common stock.

The Company cannot predict the effect that issuances or sales of its common stock, including pursuant to this offering, may have on the market price for its common stock. The issuance and sale of substantial amounts of common stock, including issuances and sales pursuant to this offering, could adversely affect the market price of the Company’s common stock.

the ability to establish and maintain new key supply sources;

•

changes in environmental and other laws and regulations to which we are subject and environmental conditions of property that we now or may in the future own or operate;

•

general economic conditions, including any potential effects arising from terrorist attacks and any hostilities or other external factors over which we have no control;

the ability to construct facilities at or below estimated costs;

•

possible increased federal, state, and local regulation of the safety of our operations;

•

the ability to successfully execute, manage, and integrate merger, acquisition, or divestiture plans, regulatory or other limitations imposed as a result of a merger, acquisition, or divestiture, and the success of the business following a merger, acquisition, or divestiture;

S-9

•

the inherent hazards and risks involved in our energy businesses;

•

risks related to cyber-attacks that could disrupt our business operations or result in failure of information technology systems;

•

the effect of competition on our businesses;

•

the impact on our cost and funding obligations under our pension and other postretirement benefit plans of potential downturns in the financial markets, lower discount rates, and costs associated with the Patient Protection and Affordable Care Act;

Our board of directors can elect at any time, and for an indefinite duration, not to declare dividends on our common stock.

On August 3, 2016, our board of directors declared a quarterly dividend of $0.3050 per share of our common stock. The dividend will be paid on October 5, 2016, to stockholders of record at the close of business on September 15, 2016 (the “record date”).

CERTAIN MATERIAL UNITED STATES FEDERAL INCOME AND ESTATE TAX CONSEQUENCES

FOR NON-U.S. HOLDERS

The following summary discusses certain material U.S. federal income and estate tax consequences to “non-U.S. holders” relating to the purchase, ownership and disposition of our common shares. As used herein, a non-U.S. holder means a beneficial owner of our common shares that is not a “U.S. Person” (as defined below) or a partnership for U.S. federal income tax purposes. This summary is based upon the provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations, rulings and judicial decisions, all as in effect on the date hereof. Those authorities may be subject to change or differing interpretations at any time, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those discussed below. There can be no assurance that the Internal Revenue Service (the “IRS”) will agree with the statements herein and we have not obtained, nor do we intend to obtain, a ruling from the IRS with respect to the U.S. federal income or estate tax consequences to a non-U.S. holder of the purchase, ownership or disposition of our common shares. A “U.S. Person” means a beneficial owner of our common shares that is for U.S. federal income tax purposes:

•

an individual who is a citizen or a resident of the United States;

•

a corporation (or any entity treated as a corporation for U.S. federal income tax purposes) that is created or organized in or under the laws of the United States, any State thereof or the District of Columbia;

•

an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

•

a trust that (1) is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) was in existence on August 20, 1996, was treated as a U.S. domestic trust immediately prior to that date, and has validly elected to continue to be treated as a U.S. domestic trust.

This summary deals only with our common shares held as capital assets within the meaning of section 1221 of the Code (generally, property held for investment). This summary does not address all of the U.S. federal income and estate tax consequences that may be relevant to a non-U.S. holder in light of such holder’s own particular circumstances, nor does it deal with special situations, such as:

•

tax consequences to non-U.S. holders who may be subject to special tax treatment, such as holders of more than 5 percent of our outstanding common shares, dealers in securities, banks, insurance companies, partnerships or other entities treated as pass-through entities for U.S. federal income tax purposes, certain former citizens or residents of the United States, “controlled foreign corporations,” “passive foreign investment companies,” corporations that accumulate earnings to avoid U.S. federal income tax, tax-exempt entities, pension plans, common trust funds, certain trusts, hybrid entities, foreign governments, international organizations and dealers or traders in securities that elect to use a mark-to-market method of accounting for their securities holdings;

•

tax consequences to persons holding our common shares as part of a hedging, integrated, constructive sale or conversion transaction or a straddle;

•

any gift tax consequences;

•

the Medicare tax imposed on certain investment income;

•

alternative minimum tax consequences, if any; or

•

any U.S. state, local or foreign tax consequences.

If a partnership (or other entity or arrangement treated as a partnership) holds our common shares, the tax treatment of a partner in the partnership generally will depend upon the status of the partner and the status and activities of the partnership. Prospective investors that are partnerships (or entities treated as partnerships for U.S. federal income tax purposes) should consult their own tax advisers regarding the U.S. federal income and estate tax considerations to them and their partners of holding our common shares.

S-14

THIS DISCUSSION IS FOR GENERAL PURPOSES ONLY. IF YOU ARE CONSIDERING THE PURCHASE OF OUR COMMON SHARES, YOU SHOULD CONSULT YOUR OWN TAX ADVISERS CONCERNING THE U.S. FEDERAL AND ESTATE TAX CONSEQUENCES TO YOU IN LIGHT OF YOUR OWN PARTICULAR CIRCUMSTANCES, AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE LAWS OF ANY OTHER TAXING JURISDICTION, THE EFFECT OF ANY CHANGES IN APPLICABLE TAX LAW, AND YOUR ENTITLEMENT TO BENEFITS UNDER AN APPLICABLE INCOME TAX TREATY.

Dividends on Common Shares

If we make a distribution of cash or other property (other than certain pro rata distributions of our common shares) in respect of our common shares, the distribution will be treated as a dividend to the extent it is paid from our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). If the amount of a distribution exceeds our current and accumulated earnings and profits, such excess first will be treated as a tax-free return of capital to the extent of the non-U.S. holder’s adjusted tax basis in our common shares and thereafter will be treated as capital gain subject to the tax treatment described below in “—Sale or Other Disposition of Common Shares.”

Distributions treated as dividends on our common shares held by a non-U.S. holder generally will be subject to U.S. federal withholding tax at a rate of 30 percent, or at a lower rate if provided by an applicable income tax treaty and the non-U.S. holder has provided the documentation required to claim benefits under such treaty to us or our agent. Generally, to claim the benefits of an income tax treaty, a non-U.S. holder will be required to provide a properly executed IRS Form W-8BEN or Form W-8BEN-E (or appropriate substitute or successor form) certifying its entitlement to benefits under the treaty.

If, however, a dividend is effectively connected with the conduct of a trade or business in the United States by the non-U.S. holder (and, if an applicable tax treaty so provides, is attributable to a permanent establishment or fixed base maintained by the non-U.S. holder in the United States), the dividend will not be subject to the 30 percent U.S. federal withholding tax (provided the non-U.S. holder has provided the appropriate documentation, generally an IRS Form W-8ECI, to the withholding agent), but the non-U.S. holder generally will be subject to U.S. federal income tax in respect of the dividend on a net income basis, and at graduated rates, in substantially the same manner as U.S. Persons. Dividends received by a non-U.S. holder that is a corporation for U.S. federal income tax purposes and which are effectively connected with the conduct of a U.S. trade or business may also be subject to a branch profits tax at the rate of 30 percent (or a lower rate if provided by an applicable tax treaty).

A non-U.S. holder that is eligible for a reduced rate of U.S. federal withholding tax under an income tax treaty may obtain a refund or credit of any excess amounts withheld by timely filing an appropriate claim for a refund together with the required information with the IRS.

Sale or Other Disposition of Common Shares

Subject to the below discussions of backup withholding and FATCA, a non-U.S. holder generally will not be subject to U.S. federal income or withholding tax on gain realized on the sale or other disposition of our common shares unless:

•

such non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of such sale or disposition, and certain other conditions are met;

•

such gain is effectively connected with the conduct by the non-U.S. holder of a trade or business in the United States (and, if an applicable tax treaty so provides, is attributable to a permanent establishment or a fixed base maintained by the non-U.S. holder in the United States); or

•

we are or have been a “U.S. real property holding corporation,” which we refer to as a “USRPHC,” under section 897 of the Code at any time during the shorter of the five-year period ending on the date of disposition and the non-U.S. holder’s holding period for its shares of our common shares.

S-15

Gain realized by such non-U.S. holder described in the first bullet above will be subject to a flat 30 percent tax (or such lower tax rate specified by an applicable income tax treaty), which may be offset by certain U.S. source capital losses.

Gain realized by a non-U.S. holder that is effectively connected with such non-U.S. holder’s conduct of a trade or business in the United States generally will be subject to U.S. federal income tax on a net income basis, and at graduated rates, in substantially the same manner as a U.S. Person (except as provided by an applicable tax treaty). In addition, if such non-U.S. holder is a corporation for U.S. federal income tax purposes, it may also be subject to a branch profits tax at the rate of 30 percent (or a lower rate if provided by an applicable tax treaty).

Generally, a corporation is a USRPHC if the fair market value of its United States real property interests equals or exceeds 50 percent 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 U.S. federal income tax purposes). Given the lack of clear guidance in this area, there can be no assurances that we are not or will not become a USRPHC. If, however, we were a USRPHC during the applicable testing period, non-U.S. holders owning (directly or indirectly) more than 5 percent of our common shares will be subject to different tax consequences and should consult their own tax advisers. U.S. federal income tax will not apply to gain realized on the sale or disposition of our common shares by a non-U.S. holder that owns (directly or indirectly) 5 percent or less of our common shares so long as our common shares are “regularly traded on an established securities market” (such as the NYSE) as defined under applicable Treasury regulations. However, we can provide no assurance that our common shares will remain regularly traded.

Information Reporting and Backup Withholding

Dividends and proceeds from the sale or other taxable disposition of our common shares are potentially subject to backup withholding at the applicable rate (currently 28 percent). In general, backup withholding will not apply to dividends on, or proceeds from the disposition of, our common shares paid by us or our paying agents, in their capacities as such, to a non-U.S. holder if the holder has provided the required certification (generally on Form W-8BEN or Form W-8BEN-E) that it is a non-U.S. holder and neither we nor our paying agent has actual knowledge (or reason to know) that the holder is a U.S. Person.

Generally, the amount of dividends on our common shares paid to a non-U.S. holder and the amount of any tax withheld from such dividends must be reported annually to the IRS and to the non-U.S. holder. Copies of these information returns may be made available by the IRS to the tax authorities of the country in which the non-U.S. holder is a resident under the provisions of an applicable tax treaty or agreement.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a non-U.S. holder’s U.S. federal income tax liability, provided the required information is furnished on a timely basis to the IRS.

Non-U.S. holders should consult their tax advisers regarding the application of the information reporting and backup withholding rules to them.

FATCA

The Foreign Account Tax Compliance Act provisions of the Hiring Incentives to Restore Employment Act and Treasury regulations thereunder, commonly referred to as “FATCA”, generally, will impose a U.S. federal withholding tax of 30 percent on certain types of payments, including payments of U.S. source interest or dividends and gross proceeds from the sale (including redemption) of certain securities producing such U.S. source interest or dividends made to (i) “foreign financial institutions” unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders or (ii) certain “non-financial foreign entities” unless they certify that they do not have any “substantial United States owners” (as defined in the Code) or furnish identifying information regarding each substantial United States owner (generally by providing an IRS Form W-8BEN or Form W-8BEN-E). In

S-16

certain circumstances, the relevant foreign financial institution or non-financial foreign entity may qualify for an exemption from these rules, which exemption is typically evidenced by providing appropriate documentation (such as an IRS Form W-8BEN or Form W-8BEN-E). In addition, an intergovernmental agreement between the United States and the jurisdiction of a foreign financial institution may modify the information reporting and related rules under FATCA.

The withholding obligations described above generally will apply to payments of dividends on the common shares, and to payments of gross proceeds from a sale or other disposition (including redemption) of the common shares occurring on or after January 1, 2019. Non-U.S. holders are urged to consult their tax advisers regarding FATCA and the application of these requirements to their investment in the common shares.

U.S. Federal Estate Tax

Common shares owned or treated as owned by an individual who is not a citizen of and who is not domiciled in the United States (as specifically defined for U.S. federal estate tax purposes) at the time of death will still be included in the individual’s gross estate for U.S. federal estate tax purposes and may be subject to U.S. federal estate tax unless an applicable estate tax treaty provides otherwise.

S-17

We and our directors and officers have agreed not to sell, transfer, pledge, offer or contract to sell, transfer or pledge, or file with the SEC a registration statement under the Securities Act, relating to any additional shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock without the prior written consent of Wells Fargo Securities, LLC and RBC Capital Markets, LLC for a period of 60 days after the date of the underwriting agreement. These restrictions will not apply to shares issued pursuant to employee benefit plans or other employee, executive or director compensation plans, pursuant to our Retirement Savings Plan, Dividend Reinvestment and Direct Stock Purchase Plan or the Chesapeake Utilities Corporation 2013 Stock and Incentive Compensation Plan.

Indemnity

We have agreed to indemnify the underwriters against certain liabilities arising out of this prospectus supplement, the accompanying prospectus and certain other materials in connection with this offering.

Our Relationship with the Underwriters

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include, among other activities, securities trading and underwriting, commercial and investment banking, financial advisory, corporate trust, investment management, investment research, principal investment, hedging, financing and brokerage activities. In the ordinary course of their respective businesses, certain of the underwriters and/or their respective affiliates have in the past and may in the future provide us and our affiliates with commercial banking, investment banking, financial advisory and other services for which they have and in the future will receive customary fees.

In particular, affiliates of Wells Fargo Securities, LLC and RBC Capital Markets, LLC serve as lenders to the Company under its Credit Agreement dated October 8, 2015, as amended. None of the net proceeds of this offering will be used to repay any amounts due to such affiliates under the credit agreement.

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 issued by us and our affiliates. If the underwriters or their respective affiliates have a lending relationship with us, they routinely hedge their credit exposure to us consistent with their customary risk management policies. The underwriters and their respective affiliates may 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 common stock offered hereby. Any such short positions could adversely affect future trading prices of the common stock offered hereby. The underwriters and certain of their respective 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 customers that they acquire, long and/or short positions in such securities and instruments.

Stabilization

The underwriters may engage in over-allotment transactions, stabilizing transactions and syndicate covering transactions in accordance with Regulation M under the Exchange Act.

•

Over-allotment involves sales by the underwriters of shares in excess of the number of shares the underwriters are obligated to purchase, which creates syndicate short positions.

•

Stabilizing transactions permit bids to purchase shares of our common stock so long as the stabilizing bids do not exceed a specified maximum.

S-19

•

Syndicate covering transactions involve purchases of our common stock in the open market after the distribution has been completed to cover syndicate short positions.

These stabilizing transactions and syndicate covering transactions may cause the price of our common stock to be higher than the price that might otherwise exist in the open market. These transactions may be effected on the New York Stock Exchange or otherwise. Neither we nor any of the underwriters make any representation that the underwriters will engage in any of the transactions described above. If commenced, these transactions may be discontinued at any time without notice. Neither we nor any of the underwriters make any representation or prediction as to the effect that the transactions described above, if commenced, may have on the market price of our common stock.

S-20

THE COMPANY

Chesapeake Utilities is a Delaware corporation formed in 1947. We are a diversified energy company engaged, through our operating divisions and subsidiaries, in various energy and other businesses. We operate primarily on the Delmarva Peninsula and in Florida, Pennsylvania, and Ohio, providing natural gas distribution and transmission, natural gas supply, gathering and processing, electric distribution, and propane distribution service. The core of our business is regulated energy services, which provides stable earnings through our utility operations. Our unregulated businesses provide opportunities to achieve returns greater than those of a traditional utility.

We operate within two reportable segments: Regulated Energy and Unregulated Energy. The Regulated Energy segment includes our natural gas distribution, natural gas transmission, 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 our propane distribution, propane wholesale marketing, natural gas marketing, and natural gas supply, gathering, and processing services, which are unregulated as to their rates and services. Also included in this segment are other unregulated energy services, such as energy-related merchandise sales; heating, ventilation, and air conditioning, plumbing, and electrical services; and electricity and steam generation services from the combined heat and power plant we recently placed into service in Nassau County, Florida.

RISK FACTORS

You should carefully consider the risks described in the documents incorporated by reference in this prospectus before making an investment decision. These risks are not the only 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, 2015 and (ii) documents we file with the SEC after the date of this prospectus that are incorporated by reference into this prospectus.

USE OF PROCEEDS

Unless otherwise specified in a prospectus supplement, the net proceeds from the sale of our Common Stock will be added to our general corporate funds and may be used for general corporate purposes including, but not limited to, financing of capital expenditures, repayment of short-term debt, financing acquisitions, investing in subsidiaries, and general working capital purposes.

DESCRIPTION OF CAPITAL STOCK

Our authorized capital stock consists of 25,000,000 shares of common stock, par value $0.4867 per share, and 2,000,000 shares of preferred stock, par value $0.01 per share.

Common Stock

Stockholders are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders and are entitled to receive dividends when and as declared by the Board of Directors out of funds legally available therefore for distribution to stockholders and to share ratably in the assets legally available for distribution to stockholders in the event of the liquidation or dissolution, whether voluntary or involuntary, of Chesapeake Utilities. Stockholders do not have cumulative voting rights in the election of directors and have no preemptive, subscription, or conversion rights. Our Common Stock is not subject to redemption by us. Each outstanding share of our Common Stock currently has associated with it one preferred stock purchase Right issued under our stockholder rights plan, which is summarized below.

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A.

Preferred Stock

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 us of, our Common Stock; and (i) the conditions or restrictions, if any, upon the creation of indebtedness or upon the issuance of any additional stock of Chesapeake Utilities.

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 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.

Stockholder Rights Plan

Our Board of Directors has adopted a stockholder rights plan (the “Rights Plan”) to protect against abusive or coercive takeover tactics that are contrary to the best interests of our stockholders. To implement

the Rights Plan, the Board of Directors declared a dividend of one preferred stock purchase Right for each outstanding share of our Common Stock held of record on September 3, 1999, and directed the issuance of a Right along with each share of our Common Stock issued thereafter for so long as provided for under the terms of the Rights Plan. Unless and until the Rights become exercisable, the Rights trade with our Common Stock and are evidenced by the certificates for our Common Stock. The Rights will become exercisable and trade independently from our Common Stock upon either: (i) a public announcement that a person or entity has acquired beneficial ownership of 15% or more of the outstanding our Common Stock, other than in a tender or exchange offer for all of the outstanding shares of our Common Stock at a price and on terms that a majority of the disinterested members of the Board of Directors determines to be adequate and in our best interests and the best interests of our stockholders (an “Acquiring Person”) or (ii) ten days after the announcement or commencement of a tender or exchange offer that would result in a person or entity becoming an Acquiring Person. Each Right, if it becomes exercisable, initially entitles the holder to purchase one-fiftieth of a share (a “Unit”) of our Series A Participating Cumulative Preferred Stock, par value $0.01 per share, at a price of $70 per Unit, subject to anti-dilution adjustments. Upon a person or entity becoming an Acquiring Person, each Right (other than the Rights held by the Acquiring Person) will become exercisable to purchase a number of shares of our Common Stock having a market value equal to two times the exercise price of the Right. If we are acquired in a merger or other business combination transaction by an Acquiring Person, each Right (other than the Rights held by the Acquiring Person) will become exercisable to purchase a number of the acquiring company’s shares of common stock having a market value equal to two times the exercise price of the Right.

The Rights expire on August 20, 2019 unless they are redeemed earlier by us at the redemption price of $0.01 per Right. We may redeem the Rights at any time before they become exercisable and thereafter only in limited circumstances.

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 securities offered pursuant to any applicable prospectus supplement to one or more underwriters for public offering and sale by them or we may sell such securities to investors directly or through agents, some of which may be dealers. We may also sell the securities through a combination of these methods. The name of any underwriter or agent involved in the offer and sale of such securities will be included in the applicable prospectus supplement.

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

(a) at a fixed price or prices, which may be changed;

(b) at market prices prevailing at the time of sale;

(d) at negotiated prices.

From time to time, we may also authorize underwriters acting as our agents to offer and sell securities upon the terms and conditions set forth in an applicable prospectus supplement. Underwriters may be deemed to have received compensation from us in the form of underwriting discounts or commissions in connection with the sale of securities offered pursuant to any applicable prospectus supplement. Underwriters may also receive commissions from purchasers of securities for whom such underwriters may act as agent. Underwriters may sell securities offered pursuant to any applicable prospectus supplement to or through dealers. Such dealers may receive compensation in the form of discounts, concessions from the underwriters, or commissions from the purchasers for whom such dealers may act as agent.

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.

We will describe in the applicable prospectus supplement any underwriting compensation we pay to underwriters or agents in connection with any offering of securities. Likewise, we will also describe any discounts, concessions, or commissions allowed by underwriters to participating dealers in the applicable prospectus supplement. Underwriters, dealers, and agents participating in the distribution of the securities may be deemed to be underwriters, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers, and agents against certain civil liabilities, including liabilities under the Securities Act, and to reimburse these persons for certain expenses. We will describe any indemnification agreements 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 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 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:

(a) The purchase by an institution of the securities covered by its delayed delivery contracts shall not at the time of delivery be prohibited under the laws of any jurisdiction in the United States to which such institution is subject; and

(b) If the securities are being sold to underwriters, we shall have sold to such underwriters the total principal amount of the offered securities less the principal amount covered by the delayed delivery contracts.

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.
