TABLE OF CONTENTS

ABOUT THIS PROSPECTUS

This prospectus is part of a Registration Statement on Form S-3 that we filed with the SEC utilizing a “shelf” registration process. Under this shelf registration process, we may, from time to time, sell any combination of securities described in this prospectus in one or more offerings. These securities also may be offered by shareholders, if so provided in a prospectus supplement hereto. We will provide specific information about any selling shareholders in one or more supplements to this prospectus. This prospectus provides you with a general description of the securities we and the selling shareholders may offer. Each time we or the selling shareholders sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering and the securities being offered. Material federal income tax considerations applicable to the offered securities will also be discussed in the applicable prospectus supplement as necessary. The prospectus supplement may also add, update or change information contained in this prospectus. You should read both this prospectus and any applicable prospectus supplement together with the additional information described below under the heading “Where You Can Find Additional Information” and “Incorporation of Certain Documents by Reference.”

This prospectus does not contain all of the information set forth in the registration statement, portions of which we have omitted as permitted by the rules and regulations of the SEC. Statements contained in this prospectus as to the contents of any contract or other document are not necessarily complete. You should refer to the copy of each contract or document filed as an exhibit to the registration statement for a complete description.

You should rely only on the information contained in or incorporated by reference into this prospectus or any applicable prospectus supplements filed with the SEC. We have not authorized anyone to provide you with different or additional information and, if you are given any information or representation about these matters that is not contained or incorporated by reference in this prospectus or a prospectus supplement, you must not rely on that information. The selling shareholders will offer to sell and seek offers to buy securities only in jurisdictions in which offers and sales are permitted. The information contained in this prospectus is accurate only as of the date of this prospectus, regardless of the time of delivery of this prospectus or any sale of securities.

Unless the context otherwise requires, all references in this prospectus to “HEICO,” the “Company,” “we,” “us,” and “our” refer to HEICO Corporation and our consolidated subsidiaries. Unless otherwise stated or indicated by context, the phrase “this prospectus” refers to the prospectus and any applicable prospectus supplement.

RISK FACTORS

Investing in our securities involves certain risks. Our business is influenced by many factors that are difficult to predict, involve uncertainties that may materially affect actual results and are often beyond our control. We have identified, or will identify, a number of these factors under the heading “Risk Factors” in our most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q, as well as in other information or reports included or incorporated by reference in this prospectus and any prospectus supplement. Before making a decision to invest in our securities, you should carefully consider these risks, as well as the other information included or incorporated by reference in this prospectus and any prospectus supplement. For additional information, see below under the heading “Where You Can Find Additional Information” and “Incorporation of Certain Documents by Reference.”

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference in this prospectus contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These statements, which in some cases, you can identify by terms such as “may,” “will,” “should,” “could,” “would,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “projects,” “predicts,” “potential” and similar expressions intended to identify forward-looking statements, relate to future events or to our future operating or financial performance and involve known and unknown risks, uncertainties and other factors which may cause our actual results, performance or achievements to be materially different from any future results, performances or achievements expressed or implied by the forward-looking statements. These statements include statements regarding our operations, cash flows, and financial position. These statements reflect our current views with respect to future events and are based on assumptions and subject to risks and uncertainties.

Although we believe that these statements are based upon reasonable assumptions, these statements expressing opinions about future outcomes and non-historical information are subject to a number of risks and uncertainties, many of which are beyond our control, and reflect future business decisions that are subject to change and, therefore, there is no assurance that the outcomes expressed in these statements will be achieved. Some of the assumptions, future results and levels of performance expressed or implied in the forward-looking statements we have made or may make in the future inevitably will not materialize, and unanticipated events may occur which will affect our results. Investors are cautioned that forward-looking statements are not guarantees of future performance and actual results or developments may differ materially from the expectations expressed in forward-looking statements contained herein. Given these uncertainties, you should not place undue reliance on these forward-looking statements. We discuss many of these risks and uncertainties in greater detail under “Risk Factors” discussed under the caption “Item 1A. Risk Factors” in Part I of our most recent Annual Report on Form 10-K or any updates discussed under the caption “Item 1A. Risk Factors” in Part II of our Quarterly Reports on Form 10-Q, together with all of the other information appearing in or incorporated by reference into this prospectus. You should read this prospectus completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of the forward-looking statements in this prospectus by these cautionary statements. We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise, except as may be required under the securities laws of the United States. You are advised, however, to consult any additional disclosures we make in our reports filed with the SEC.

USE OF PROCEEDS

We will describe our intended use of the net proceeds from any particular offering in the related prospectus supplement. We will not receive any proceeds from sales of securities by the selling shareholders.

SELLING SHAREHOLDERS

If the registration statement of which this prospectus forms a part is used by selling shareholders for the resale of any securities registered thereunder, information about such selling shareholders, their beneficial ownership of the securities and their relationship with us will be set forth in a prospectus supplement, in a post-effective amendment, or in filings we make with the SEC under the Exchange Act that are incorporated by reference to such registration statement.

DESCRIPTION OF OUR CAPITAL STOCK

General

We are authorized to issue up to 150,000,000 shares of Common Stock, par value $.01 per share, 150,000,000 shares of Class A Common Stock, par value $.01 per share, and 10,000,000 shares of Preferred Stock, par value $.01 per share. As of July 9, 2026, (i) 55,235,561 shares of Common Stock were outstanding and such shares were held by approximately 228 holders of record and (ii) 84,502,147 shares of Class A Common Stock were outstanding and such shares were held by approximately 253 holders of record. None of the Preferred Stock is outstanding.

The transfer agent and registrar for the Common Stock and Class A Common Stock is Broadridge Financial Solutions, telephone number (800) 353-0103.

The following descriptions of the Common Stock, the Class A Common Stock and the Preferred Stock are based on our amended and restated Articles of Incorporation, as amended (“Articles of Incorporation”), amended and restated Bylaws and applicable Florida law.

Common Stock

Each holder of Common Stock is entitled to one vote for each share owned of record on all matters presented to the shareholders. In the event of a liquidation, dissolution or winding up of the Company, the holders of Common Stock are entitled to share equally and ratably in the assets of the Company, if any, remaining after the payment of all of our debts and liabilities and the liquidation preference of any outstanding Preferred Stock. The Common Stock has no preemptive rights, no cumulative voting rights and no redemption, sinking fund or conversion provisions. As of July 9, 2026, 5,008,363 shares are reserved for issuance as either Common Stock or Class A Common Stock under our existing stock option plans.

Class A Common Stock

Each holder of Class A Common Stock is entitled to the identical rights as the holders of Common Stock, except that each share of Common Stock will entitle the holder thereof to one vote in respect of matters submitted for the vote of holders of Common Stock, whereas each share of Class A Common Stock will entitle the holder thereof to one-tenth of a vote on such matters.

Dividend Rights

The Florida Business Corporation Act and our Articles of Incorporation do not require our Board of Directors to declare dividends on our Common Stock or Class A Common Stock. The declaration of any dividend on our Common Stock or Class A Common Stock is a matter to be acted upon by our Board of Directors in its sole discretion. Our payment of dividends on our Common Stock or Class A Common Stock in the future will be determined by our Board of Directors in its sole discretion and will depend on business conditions, our financial condition, earnings and liquidity, and other factors.

The Florida Business Corporation Act authorizes the Board of Directors to make distributions, including repurchases of stock, to its shareholders subject to restrictions in the corporation’s Articles of Incorporation. The Florida Business Corporation Act also provides that a corporation may not make distributions to its shareholders if, after giving effect to the dividend or distribution, the corporation would be unable to pay its debts as they become due in the usual course of business, or if the total assets of the corporation would be less than the sum of its total liabilities plus the amount needed, if the corporation were dissolved at the time the distribution was paid, to satisfy the preferential rights of shareholders whose preferential rights upon dissolution of the corporation are greater than those of the shareholders receiving the dividend.

Shareholders of Common Stock and Class A Common Stock are entitled to receive dividends if, as and when declared by the Board of Directors out of funds legally available therefor, subject to the dividend and liquidation rights of any Preferred Stock that may be issued and outstanding and subject to any dividend restrictions in our revolving credit facility. No dividends or other distributions (including redemptions or repurchases of shares of capital stock) may be made if, after giving effect to any such dividends or distributions, we would not be able to pay our debts as they become due in the usual course of business or our total assets would be less than the sum of our total liabilities plus the amount that would be needed at the time of a liquidation to satisfy the preferential rights of any holders of Preferred Stock.

We have historically paid semi-annual cash dividends on both our Class A Common Stock and Common Stock. During fiscal 2025, we paid an aggregate cash dividend of $0.23 per share, which represents a 10% increase over the aggregate cash dividend of $0.21 per share paid during fiscal 2024. In December 2025, our Board of Directors declared a semi-annual cash dividend of $0.12 per share paid in January 2026. Also, in June 2026, our Board of Directors declared our 96th consecutive semi-annual cash dividend since 1979 of $0.13 per share payable in July 2026.

Our Board of Directors will continue to review our dividend policy and will regularly evaluate whether dividends should be paid in cash or stock, as well as what amounts should be paid. Our ability to pay dividends could be affected by a number of factors, including, but not limited to, future business performance, liquidity, capital needs, and alternative investment opportunities.

Preferred Stock

Our Board of Directors is authorized, without further shareholder action, to designate and issue from time to time one or more series of Preferred Stock. The Board of Directors may fix and determine the designations, preferences and relative rights and qualifications, limitations or restrictions of any series of Preferred Stock so established, including voting powers, dividend rights, liquidation preferences, redemption rights and conversion privileges. Because the Board of Directors has the power to establish the preferences and rights of each series of Preferred Stock, it may afford the holders of any series of Preferred Stock preferences and rights, voting or otherwise senior to the rights of holders of Common Stock and Class A Common Stock. As of the date of this prospectus, the Board of Directors has not issued any Preferred Stock.

Anti-takeover Effects of Certain Provisions of Florida Law, Our Articles of Incorporation and Bylaws, and the Preferred Stock Purchase Rights

Articles and Bylaws. Some of the provisions of our Articles of Incorporation and amended and restated Bylaws may be deemed to have anti-takeover effects and may discourage, delay, defer or prevent a takeover attempt that a shareholder might consider in its best interest. These provisions do the following:

 Accordingly, without shareholder approval, the Board of Directors can, among other things,

Florida Law. Furthermore, some of the provisions of the Florida Business Corporation Act could have the effect of delaying, deferring or preventing a change in control.

DESCRIPTION OF DEBT SECURITIES

The following description, together with the additional information we include in any applicable prospectus supplement, summarizes the material terms and provisions of the debt securities that we may offer under this prospectus. While the terms we have summarized below will generally apply to any future debt securities we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. The terms of any debt securities we offer under a prospectus supplement may differ from the terms we describe below.

We may offer debt securities in the form of either senior debt securities or subordinated debt securities. The senior debt securities and the subordinated debt securities are together referred to in this prospectus as the “debt securities.” Unless otherwise specified in a supplement to this prospectus, the senior debt securities will be our direct, unsecured obligations and will rank equally with all of our other unsecured and unsubordinated indebtedness. The subordinated debt securities generally will be entitled to payment only after payment of our senior debt. See “Description of Debt Securities - Subordination” below.

The debt securities will be issued under an indenture between us and a trustee. We have summarized below the general features of the debt securities to be governed by the indenture. The form of summary is not complete. The form of indenture has been filed as an exhibit to the registration statement that we have filed with the SEC, of which this prospectus forms a part. We encourage you to read the applicable prospectus supplements related to the debt securities that we may offer under this prospectus, as well as the indenture. Capitalized terms used in the summary have the meanings specified in the indenture.

General

The terms of each series of debt securities will be established by or pursuant to a resolution of our Board of Directors, or a committee thereof, and set forth or determined in the manner provided in an officers’ certificate or by a supplemental indenture. The particular terms of each series of debt securities will be described in a prospectus supplement relating to such series, including any pricing supplement.

We can issue an unlimited amount of debt securities under the indenture that may be in one or more series with the same or various maturities, at par, at a premium or at a discount. We will set forth in a prospectus supplement, including any pricing supplement, relating to any series of debt securities being offered, the aggregate principal amount and the following terms of the debt securities:

We may issue debt securities that provide for an amount less than their stated principal amount to be due and payable upon declaration of acceleration of their maturity pursuant to the terms of the indenture. We will provide you with information on the federal income tax considerations and other special considerations applicable to any of these debt securities in the applicable prospectus supplement.

Conversion or Exchange Rights

We will set forth in the prospectus supplement the terms on which a series of debt securities may be convertible into or exchangeable for common stock or other securities of ours or a third-party, including the conversion or exchange rate, as applicable, or how it will be calculated, and the applicable conversion or exchange period. We will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of our securities or the securities of a third-party that the holders of the series of debt securities receive upon conversion or exchange would, under the circumstances described in those provisions, be subject to adjustment, or pursuant to which those holders would, under those circumstances, receive other property upon conversion or exchange, for example in the event of our merger or consolidation with another entity.

Certain Covenants

The indenture includes certain customary covenants requiring us, among other things, to:

Consolidation, Merger and Sale of Assets

The indenture provides that we may not consolidate with or merge into any other person, or convey, transfer or lease all or substantially all of our assets, unless:

Upon any consolidation or merger, or any conveyance, transfer or lease of all or substantially all of the assets of the Company in accordance with the indenture, the successor company will succeed to, and be substituted for, and may exercise every right and power of ours under the indenture with the same effect as if the successor company had been named in our place in the indenture. The predecessor person will (except in the case of a lease) be discharged from all obligations and covenants under the indenture and any debt securities issued thereunder.

Events of Default

With respect to the debt securities of any series, an “Event of Default” means:

If there is a continuing Event of Default with respect to the debt securities of any series (other than an Event of Default regarding certain events of bankruptcy, insolvency or reorganization relating to us), either the trustee or the holders of at least 25% of the outstanding principal amount of the debt securities of such series may declare the principal amount of all of the debt securities of that series to be due and payable immediately. In the case of an Event of Default resulting from certain events of bankruptcy, insolvency or reorganization relating to us, the principal of and accrued and unpaid interest, if any, on all outstanding debt securities will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of outstanding debt securities. At any time after the trustee or the holders, as the case may be, declare an acceleration with respect to the debt securities of any series, but before a judgment or decree based on such acceleration has been obtained, the holders of a majority in principal amount of the outstanding debt securities of such series may, under certain conditions, cancel such acceleration if we have cured all Events of Default (other than the nonpayment of accelerated principal) with respect to the debt securities of such series or all such Events of Default have been waived as provided in the indenture.

The indenture provides that if there is a continuing Event of Default, the trustee need not exercise any of its rights or powers under the indenture at the request or direction of any of the holders of debt securities, unless such holders have offered, and if requested, provided, to the trustee security or indemnity satisfactory to the trustee in its sole discretion. Subject to such provisions for security or indemnification of the trustee and certain other conditions, the holders of a majority in aggregate principal amount of the outstanding debt securities of a series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power the trustee holds with respect to the debt securities of that series.

No holder of any debt security of any series will have any right to institute any proceeding with respect to the indenture or for any remedy under the indenture unless:

The holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, and any premium or interest on, such debt security on or after the date or dates they are to be paid as expressed in such debt security and to institute suit for the enforcement of any such payment.

We are required to furnish to the trustee annually a statement as to the absence of certain defaults under the indenture. The indenture provides that the trustee need not provide holders of debt securities notice of any default (other than the nonpayment of principal or any premium or interest) if it considers it in the interest of the holders of debt securities not to provide such notice.

Modification and Waiver

We and the trustee may amend the indenture with the consent of the holders of a majority of the aggregate principal amount of the outstanding debt securities of each series affected by the amendment. However, no such amendment may, without the consent of the holders of all then outstanding debt securities of the affected series:

The holders of a majority of the aggregate principal amount of the outstanding debt securities of any series may waive, insofar as that series is concerned, future compliance by us with certain restrictive covenants of the indenture. The holders of at least a majority in aggregate principal amount of the outstanding debt securities of any series may waive any past default or Event of Default under the indenture with respect to that series, except a failure by us to pay the principal of, or any premium or interest on, any debt securities of that series or a provision that cannot be modified or amended without the consent of the holders of all outstanding debt securities of the affected series.

Satisfaction and Discharge

The indenture will cease to be of further effect with respect to the debt securities of any series when:

Notwithstanding the above, certain provisions of the indenture will survive, including with respect to certain rights, obligations and immunities of the trustee.

Defeasance

The debt securities or any series of debt securities may be defeased at any time in accordance with the terms set forth in the indenture. Any defeasance may terminate all of our obligations (with limited exceptions) with respect to such debt securities and the indenture (“legal defeasance”), or it may terminate only our obligations under any restrictive covenant that may be applicable to such debt securities (“covenant defeasance”).

We may exercise our legal defeasance option even though we have also exercised our covenant defeasance option. If we exercise our legal defeasance option, the debt securities may not be accelerated because of an Event of Default. If we exercise the covenant defeasance option, the debt securities may not be accelerated by reference to any restrictive covenants which apply to the debt securities.

To exercise either defeasance option, we must:

If we exercise our option to effect a covenant defeasance as described above and the debt securities are thereafter declared due and payable because of an Event of Default (other than an Event of Default caused by failing to comply with the covenants that are defeased), the amount of money and securities we have deposited with the trustee would be sufficient to pay amounts due on the debt securities on their respective due dates but may not be sufficient to pay amounts due on the debt securities at the time of acceleration resulting from such Event of Default. However, we would remain liable for such payments.

Subordination

Unless indicated differently in a prospectus supplement, our subordinated debt securities will be subordinated in right of payment to the prior payment in full of all our senior debt. This means that upon:

before the holders of any of the subordinated debt securities are entitled to receive any payment. So long as any of the events in the bullet points above has occurred and is continuing, any amounts payable on the subordinated debt securities will instead be paid directly to the holders of all senior debt to the extent necessary to pay the senior debt in full and, if any payment is received by the subordinated indenture trustee under the subordinated indenture or the holders of any of the subordinated debt securities before all senior debt is paid in full, the payment or distribution must be paid over to the holders of the unpaid senior debt. Subject to paying the senior debt in full, the holders of the subordinated debt securities will be subrogated to the rights of the holders of the senior debt to the extent that payments are made to the holders of senior debt out of the distributive share of the subordinated debt securities.

The term “senior debt” means with respect to the subordinated debt securities, the principal of, premium, if any, and interest, if any, on and any other payment in respect of indebtedness due pursuant to any of the following, whether outstanding on the date the subordinated debt securities are issued or thereafter incurred, created or assumed:

unless, in the case of any particular indebtedness, renewal, extension or refunding, the instrument creating or evidencing the same or the assumption or guarantee of the same by its terms provides that such indebtedness, renewal, extension or refunding is not superior in right of payment to or is pari passu with such securities.

Due to the subordination, if our assets are distributed upon insolvency, certain of our general creditors may recover more, ratably, than holders of subordinated debt securities. The subordination provisions will not apply to money and securities held in trust under the satisfaction and discharge and the defeasance provisions of the applicable subordinated indenture.

The subordinated debt securities and the subordinated indenture do not limit our ability to incur additional indebtedness, including indebtedness that will rank senior to the subordinated debt securities. We may incur substantial additional amounts of indebtedness in the future.

Governing Law

Unless otherwise described in any prospectus supplement, the indenture and the debt securities will be governed by, and construed in accordance with, the internal laws of the State of New York.

DESCRIPTION OF DEPOSITARY SHARES

This section describes the general terms of the depositary shares we may offer and sell by this prospectus. This prospectus and any accompanying prospectus supplement will contain the material terms and conditions for the depositary shares. The accompanying prospectus supplement may add, update, or change the terms and conditions of the depositary shares as described in this prospectus.

General

We may, at our option, elect to offer depositary shares, each representing a fraction (to be set forth in the prospectus supplement relating to a particular series of preferred stock) of a share of a particular class or series of preferred stock as described below. In the event we elect to do so, depositary receipts evidencing depositary shares will be issued to the public.

The shares of any class or series of preferred stock represented by depositary shares will be deposited under a deposit agreement among us, a depositary selected by us, and the holders of the depositary receipts. The depositary will be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, in proportion to the applicable fraction of a share of preferred stock represented by such depositary share, to all of the rights and preferences of the shares of preferred stock represented by the depositary share, including dividend, voting, redemption and liquidation rights.

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional shares of the related class or series of preferred shares in accordance with the terms of the offering described in the related prospectus supplement.

Pending the preparation of definitive depositary receipts, the depositary may, upon our written order, issue temporary depositary receipts substantially identical to, and entitling the holders thereof to all the rights pertaining to, the definitive depositary receipts but not in definitive form. Definitive depositary receipts will be prepared without unreasonable delay, and temporary depositary receipts will be exchangeable for definitive depositary receipts without charge to the holder.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions received for the preferred stock to the entitled record holders of depositary shares in proportion to the number of depositary shares that the holder owns on the relevant record date; provided, however, that if we or the depositary is required by law to withhold an amount on account of taxes, then the amount distributed to the holders of depositary shares shall be reduced accordingly. The depositary will distribute only an amount that can be distributed without attributing to any holder of depositary shares a fraction of one cent. The depositary will add the undistributed balance to and treat it as part of the next sum received by the depositary for distribution to holders of the depositary shares.

If there is a non-cash distribution, the depositary will distribute property received by it to the entitled record holders of depositary shares, in proportion, insofar as possible, to the number of depositary shares owned by the holders, unless the depositary determines, after consultation with us, that it is not feasible to make such distribution. If this occurs, the depositary may, with our approval, sell such property and distribute the net proceeds from such sale to the holders. The deposit agreement also will contain provisions relating to how any subscription or similar rights that we may offer to holders of the preferred stock will be available to the holders of the depositary shares.

Withdrawal of Shares

Upon surrender of the depositary receipts at the corporate trust office of the depositary, unless the related depositary shares have previously been called for redemption, converted or exchanged into our other securities, the holder of the depositary shares evidenced thereby is entitled to delivery of the number of whole shares of the related class or series of preferred stock and any money or other property represented by such depositary shares. Holders of depositary receipts will be entitled to receive whole shares of the related class or series of preferred stock on the basis set forth in the prospectus supplement for such class or series of preferred stock, but holders of such whole shares of preferred stock will not thereafter be entitled to exchange them for depositary shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock to be withdrawn, the depositary will deliver to such holder at the same time a new depositary receipt evidencing such excess number of depositary shares. In no event will fractional shares of preferred stock be delivered upon surrender of depositary receipts to the depositary.

Conversion, Exchange and Redemption

If any class or series of preferred stock underlying the depositary shares may be converted or exchanged, each record holder of depositary receipts representing the shares of preferred stock being converted or exchanged will have the right or obligation to convert or exchange the depositary shares represented by the depositary receipts.

Whenever we redeem or convert shares of preferred stock held by the depositary, the depositary will redeem or convert, at the same time, the number of depositary shares representing the preferred stock to be redeemed or converted. The depositary will redeem the depositary shares from the proceeds it receives from the corresponding redemption of the applicable series of preferred stock. The depositary will mail notice of redemption or conversion to the record holders of the depositary shares that are to be redeemed between 30 and 60 days before the date fixed for redemption or conversion. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per share on the applicable class or series of preferred stock. If less than all the depositary shares are to be redeemed, the depositary will select which shares are to be redeemed by lot on a pro rata basis or by any other equitable method as the depositary may decide.

After the redemption or conversion date, the depositary shares called for redemption or conversion will no longer be outstanding. When the depositary shares are no longer outstanding, all rights of the holders will end, except the right to receive money, securities or other property payable upon redemption or conversion of the depositary shares.

Voting the Preferred Stock

When the depositary receives notice of a meeting at which the holders of the particular class or series of preferred stock are entitled to vote, the depositary will mail the particulars of the meeting to the record holders of the depositary shares. Each record holder of depositary shares on the record date may instruct the depositary on how to vote the shares of preferred stock underlying the holder’s depositary shares. The depositary will try, if practical, to vote the number of shares of preferred stock underlying the depositary shares according to the instructions. We will agree to take all reasonable action requested by the depositary to enable it to vote as instructed.

Amendment and Termination of the Deposit Agreement

We and the depositary may agree at any time to amend the deposit agreement and the depositary receipt evidencing the depositary shares. Any amendment that (a) imposes or increases certain fees, taxes or other charges payable by the holders of the depositary shares as described in the deposit agreement or (b) otherwise materially adversely affects any substantial existing rights of holders of depositary shares, will not take effect until such amendment is approved by the holders of at least a majority of the depositary shares then outstanding. Any holder of depositary shares that continues to hold its shares after such amendment has become effective will be deemed to have agreed to the amendment.

We may direct the depositary to terminate the deposit agreement by mailing a notice of termination to holders of depositary shares at least 30 days before termination. The depositary may terminate the deposit agreement if 90 days have elapsed after the depositary delivered written notice of its election to resign and a successor depositary is not appointed. In addition, the deposit agreement will automatically terminate if:

Reports and Obligations

The depositary will forward to the holders of depositary shares all reports and communications from us that are delivered to the depositary and that we are required by law, the rules of an applicable securities exchange or our Articles of Incorporation to furnish to the holders of the preferred stock. Neither we nor the depositary will be liable if the depositary is prevented or delayed by law or any circumstances beyond its control in performing its obligations under the deposit agreement. The deposit agreement limits our obligations to performance in good faith of the duties stated in the deposit agreement. The depositary assumes no obligation and will not be subject to liability under the deposit agreement except to perform such obligations as are set forth in the deposit agreement without negligence or bad faith. Neither we nor the depositary will be obligated to prosecute or defend any legal proceeding connected with any depositary shares or class or series of preferred stock unless the holders of depositary shares requesting us to do so furnish us with a satisfactory indemnity. In performing our obligations, we and the depositary may rely and act upon the advice of our counsel or accountants, on any information provided to us by a person presenting shares for deposit, any holder of a receipt, or any other document believed by us or the depositary to be genuine and to have been signed or presented by the proper party or parties.

Payment of Fees and Expenses

We will pay all fees, charges and expenses of the depositary, including the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary shares will pay taxes and governmental charges and any other charges as are stated in the deposit agreement for their accounts.

Resignation and Removal of Depositary

At any time, the depositary may resign by delivering notice to us, and we may remove the depositary at any time. Resignations or removals will take effect upon the appointment of a successor depositary and its acceptance of the appointment. The successor depositary must be appointed within 90 days after the delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000.

DESCRIPTION OF WARRANTS

This section describes the general terms of the warrants that we may offer and sell by this prospectus. This prospectus and any accompanying prospectus supplement will contain the material terms and conditions for each warrant. The accompanying prospectus supplement may add, update or change the terms and conditions of the warrants as described in this prospectus.

General

We may issue warrants to purchase debt securities or equity securities, including Common Stock, Class A Common Stock or preferred stock. Warrants may be issued independently or together with any securities and may be attached to or separate from those securities. The warrants will be issued under warrant agreements to be entered into between us and a bank or trust company, as warrant agent, all of which will be described in the prospectus supplement relating to the warrants we are offering. The warrant agent will act solely as our agent in connection with the warrants and will not have any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. A copy of the warrant agreement will be filed with the SEC in connection with the offering of the warrants.

Debt Warrants

We may issue warrants for the purchase of our debt securities. As explained below, each debt warrant will entitle its holder to purchase debt securities at an exercise price set forth in, or to be determinable as set forth in, the related prospectus supplement. Debt warrants may be issued separately or together with debt securities.

The debt warrants are to be issued under debt warrant agreements to be entered into between us, and one or more banks or trust companies, as debt warrant agent, as will be set forth in the prospectus supplement relating to the debt warrants being offered by the prospectus supplement and this prospectus. A copy of the debt warrant agreement, including a form of the debt warrant certificate representing the debt warrants, will be filed with the SEC in connection with the offering of the debt warrants.

The particular terms of each issue of debt warrants, the debt warrant agreement relating to the debt warrants and the debt warrant certificates representing debt warrants will be described in the applicable prospectus supplement, including, as applicable:

Debt warrant certificates will be exchangeable for new debt warrant certificates of different denominations and, if in registered form, may be presented for registration of transfer, and debt warrants may be exercised at the corporate trust office of the debt warrant agent or any other office indicated in the related prospectus supplement. Before the exercise of debt warrants, holders of debt warrants will not be entitled to payments of principal, of premium, if any, or interest, if any, on the debt securities purchasable upon exercise of the debt warrants, or to enforce any of the covenants in the indenture.

Equity Warrants

We may issue warrants for the purchase of our equity securities, such as our Common Stock, Class A Common Stock or preferred stock. As explained below, each equity warrant will entitle its holder to purchase equity securities at an exercise price set forth in, or to be determinable as set forth in, the related prospectus supplement. Equity warrants may be issued separately or together with equity securities.

The equity warrants are to be issued under equity warrant agreements to be entered into between us and one or more banks or trust companies, as equity warrant agent, as will be set forth in the prospectus supplement relating to the equity warrants being offered by the prospectus supplement and this prospectus. A copy of the equity warrant agreement, including a form of the equity warrant certificate representing the equity warrants, will be filed with the SEC in connection with the offering of the equity warrants.

The particular terms of each issue of equity warrants, the equity warrant agreement relating to the equity warrants and the equity warrant certificates representing equity warrants will be described in the applicable prospectus supplement, including, as applicable:

Holders of equity warrants will not be entitled, solely by virtue of being holders, to vote, to consent, to receive dividends, to receive notice as shareholders with respect to any meeting of shareholders for the election of directors or any other matter, or to exercise any rights whatsoever as a holder of the equity securities purchasable upon exercise of equity warrants.

DESCRIPTION OF UNITS

We may issue units comprised of one or more debt securities, common stock, shares of preferred stock, and warrants in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

The prospectus supplement may describe:

Unit Agreements

We will issue the units under one or more unit agreements to be entered into between us and a bank or other financial institution, as unit agent. We may add, replace or terminate unit agents from time to time. We will identify the unit agreement under which each series of units will be issued and the unit agent under that agreement in the prospectus supplement.

The following provisions will generally apply to all unit agreements unless otherwise stated in the prospectus supplement.

Enforcement of Rights

The unit agent under a unit agreement will act solely as our agent in connection with the units issued under that agreement. The unit agent will not assume any obligation or relationship of agency or trust for or with any holders of those units or of the securities comprising those units. The unit agent will not be obligated to take any action on behalf of those holders to enforce or protect their rights under the units or the included securities.

Except as indicated in the next paragraph, a holder of a unit may, without the consent of the unit agent or any other holder, enforce its rights as holder under any security included in the unit, in accordance with the terms of that security and the indenture, warrant agreement or other instrument under which that security is issued.

Notwithstanding the foregoing, a unit agreement may limit or otherwise affect the ability of a holder of units issued under that agreement to enforce its rights, including any right to bring a legal action, with respect to those units or any securities, other than debt securities that are included in those units. Limitations of this kind will be described in the prospectus supplement.

Modification Without Consent of Holders

Unless provided otherwise in an applicable prospectus supplement, we and the applicable unit agent may amend any unit or unit agreement without the consent of any holder:

We do not need any approval to make changes that affect only units to be issued after the changes take effect. We may also make changes that do not adversely affect a particular unit in any material respect, even if they adversely affect other units in a material respect. In those cases, we do not need to obtain the approval of the holder of the unaffected unit; we need only obtain any required approvals from the holders of the affected units.

Modification With Consent of Holders

Unless provided otherwise in an applicable prospectus supplement, we may not amend any particular unit or a unit agreement with respect to any particular unit unless we obtain the consent of the holder of that unit, if the amendment would:

Unless provided otherwise in an applicable prospectus supplement, any other change to a particular unit agreement and the units issued under that agreement would require the following approval:

These provisions regarding changes with majority approval also apply to changes affecting any securities issued under a unit agreement, as the governing document.

In each case, the required approval must be given by written consent.

Unit Agreements Will Not Be Qualified Under The Trust Indenture Act

No unit agreement will be qualified as an indenture, and no unit agent will be required to qualify as a trustee, under the Trust Indenture Act. Therefore, holders of units issued under unit agreements will not have the protections of the Trust Indenture Act with respect to their units.

Title

We and the unit agents and any of our respective agents may treat the registered holder of any unit certificate as an absolute owner of the units evidenced by that certificate for any purpose and as the person entitled to exercise the rights attaching to the units so requested, despite any notice to the contrary.

PLAN OF DISTRIBUTION

We and the selling shareholders may sell the securities described in this prospectus from time to time in one or more transactions:

We and the selling shareholders may distribute the securities from time to time in one or more transactions at:

Direct Sales

We and the selling shareholders may sell the securities directly to institutional investors or others. A prospectus supplement will describe the terms of any sale of securities we or the selling shareholders are offering hereunder.

To Underwriters

The applicable prospectus supplement will name any underwriter involved in a sale of securities. Underwriters may offer and sell securities at a fixed price or prices, which may be changed, or from time to time at market prices or at negotiated prices. Underwriters may be deemed to have received compensation from us from sales of securities in the form of underwriting discounts or commissions and may also receive commissions from purchasers of securities for whom they may act as agent.

Underwriters may sell securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions (which may be changed from time to time) from the purchasers for whom they may act as agent.

Unless otherwise provided in a prospectus supplement, the obligations of any underwriters to purchase securities or any series of securities will be subject to certain conditions precedent, and the underwriters will be obligated to purchase all such securities if any are purchased.

Through Agents and Dealers

We and the selling shareholders will name any agent involved in a sale of securities, as well as any commissions payable by us to such agent, in a prospectus supplement. Unless we indicate differently in the prospectus supplement, any such agent will be acting on a reasonable efforts basis for the period of its appointment.

If a dealer is utilized in the sale of the securities being offered pursuant to this prospectus, the securities will be sold to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

Delayed Delivery Contracts

If we so specify in the applicable prospectus supplement, underwriters, dealers and agents will be authorized to solicit offers by certain institutions to purchase securities pursuant to contracts providing for payment and delivery on future dates. Such contracts will be subject to only those conditions set forth in the applicable prospectus supplement.

The underwriters, dealers and agents will not be responsible for the validity or performance of the contracts. We will set forth in the prospectus supplement relating to the contracts the price to be paid for the securities, the commissions payable for solicitation of the contracts and the date in the future for delivery of the securities.

GENERAL INFORMATION

Underwriters, dealers and agents participating in a sale of the securities may be deemed to be underwriters as defined in the Securities Act, 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, under the Securities Act. We and the selling shareholders may have agreements with underwriters, dealers and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act, and to reimburse them for certain expenses.

Underwriters or agents and their associates may be customers of, engage in transactions with or perform services for us or our affiliates in the ordinary course of business.

Unless we indicate differently in a prospectus supplement, we will not list the securities on any securities exchange, other than shares of our Common Stock and Class A Common Stock. The securities, except for our Common Stock and Class A Common Stock, will be a new issue of securities with no established trading market. Any underwriters that purchase securities for public offering and sale may make a market in such securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We make no assurance as to the liquidity of or the trading markets for any securities.

The filing of the registration statement in which this prospectus is included does not preclude us from issuing securities in a transaction that is exempt from the registration provisions of the securities laws.

Certain legal matters relating to the offering will be passed upon for us and the selling shareholders by Akerman LLP, Miami, Florida.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The following table sets forth all expenses in connection with the issuance and distribution of the securities being registered. All amounts shown are estimates, except for the SEC registration fee:

Item 15. Indemnification of Directors and Officers.

Section 607.0851 of the Florida Business Corporation Act (“FBCA”) provides that a Florida corporation shall have the power to indemnify any person who was or is a party to a proceeding (other than an action by, or in the right of, the corporation), by reason of the fact that he or she is or was a director or officer of the corporation against liability incurred in connection with such proceeding, including any appeal thereof, if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

Section 607.0851(4) of the FBCA provides that a Florida corporation shall have the power to indemnify any person, who was or is a party to any proceeding by or in the right of the corporation to procure a judgment in its favor by reason of the fact that he or she is or was a director or officer of the corporation against expenses and amounts paid in settlement not exceeding, in the judgment of the board of directors, the estimated expense of litigating the proceeding to conclusion, actually and reasonably incurred in connection with the defense or settlement of such proceeding, including any appeal thereof. Such indemnification shall be authorized if such person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation.

Section 607.0852 of the FBCA further provides that the corporation must indemnify an individual who is or was a director or officer who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which the individual was a party because he or she is or was a director or officer of the corporation against expenses incurred by the individual in connection with the proceeding. Also, according to Section 607.0858 of the FBCA, indemnification provided by Section 607.0851 and 607.0852 and advancement of expenses provided pursuant to Section 607.0853 are not exclusive.

Section 607.0857 of the FBCA further provides that the corporation shall have the power to purchase and maintain insurance on behalf of a director or officer of the corporation or who, while a director or officer of the corporation, is or was serving at the corporation’s request as a director, officer, manager, member, partner, trustee, employee, or agent of another domestic or foreign corporation, limited liability company, partnership, joint venture, trust, employee benefit plan, or other enterprise or entity,  against any liability asserted against him or her or incurred by him or her in any such capacity or arising out of his or her status as such, whether or not the corporation would have the power to indemnify or advance expenses to him or her against such liabilities under Chapter 607 of the FBCA.

Notwithstanding the foregoing, Section 607.0859 of the FBCA provides that indemnification or advancement of expenses shall not be made to or on behalf of any director or officer if a judgment or other final adjudication establishes that his or her actions, or omissions to act, were material to the cause of action so adjudicated and constitute: (i) a violation of the criminal law, unless the director or officer had reasonable cause to believe his or her conduct was lawful or had no reasonable cause to believe his or her conduct was unlawful; (ii) a transaction from which the director or officer derived an improper personal benefit; (iii) in the case of a director, a circumstance under which the liability provisions regarding unlawful distributions pursuant to Section 607.0834 are applicable; or (iv) willful or intentional misconduct or a conscious disregard for the best interests of the corporation in a proceeding by or in the right of the corporation to procure a judgment in its favor or in a proceeding by or in the right of a shareholder.

Section 607.0831 of the FBCA provides that a director of a Florida corporation is not personally liable for monetary damages to the corporation or any other person for any statement, vote, decision, or failure to act, by a director, unless: (i) the director breached or failed to perform his or her duties as a director; and (ii) the director’s breach of, or failure to perform, those duties constitutes: (A) a violation of criminal law, unless the director had reasonable cause to believe his or her conduct was lawful or had no reasonable cause to believe his or her conduct was unlawful; (B) a circumstance under which the transaction at issue is one from which the director derived an improper personal benefit, either directly or indirectly; (C) a circumstance under which the liability provisions regarding unlawful distributions pursuant to Section 607.0834 are applicable; (D) in a proceeding by or in the right of the corporation to procure a judgment in its favor or by or in the right of a shareholder, conscious disregard for the best interest of the corporation, or willful or intentional misconduct; or (E) in a proceeding by or in the right of someone other than the corporation or a shareholder, recklessness or an act or omission which was committed in bad faith or with malicious purpose or in a manner exhibiting wanton and willful disregard of human rights, safety, or property.

The Articles of Incorporation of HEICO provide that it may indemnify its executive officers and directors to the fullest extent permitted by law.

The amended and restated Bylaws of HEICO provide that it shall indemnify and hold harmless each person who shall serve at any time as a director or officer of the corporation from and against any and all claims and liabilities to which such person shall have become subject by reason of his having heretofore or hereafter been a director or officer of the corporation, or by reason of any action alleged to have been heretofore or hereafter taken or omitted by him as such director or officer, and shall reimburse each such person for all legal and other expenses reasonably incurred by him in connection with any such claim or liability; provided, however, that no such person shall be indemnified against, or be reimbursed for any expense incurred in connection with any claim or liability which shall be finally adjudged to arise out of his own gross negligence or willful misconduct. The rights accruing to any person under Article 5 of the amended and restated Bylaws shall not exclude any other rights to which he may be lawfully entitled, nor shall anything herein contained restrict the right of the corporation to indemnify or reimburse such person in any proper case even though not specifically herein provided for. HEICO, its directors, officers, employees and agents shall be fully protected in taking any action or making any payment under this Article, or in refusing so to do, in reliance upon the advice of counsel.
