In 2021, we derived 69.0% of our Electricity segment revenues from our operations in the U.S. and 31.0% from the rest of the world. In the nine months ended September30, 2022, we derived 70.3% of our Electricity segment revenues from our operations in the United States and 29.7% from the rest of the world.

•Product Segment.    In the Product segment, which contributed 7.1% and 7.4% of our total revenues in the year ended December31, 2021 and nine months ended September30, 2022, respectively, we design, manufacture and sell equipment for geothermal and recovered energy-based electricity generation and remote power units and provide services relating to the engineering, procurement and construction of geothermal and recovered energy-based power plants. In 2021, we derived 11.5% of our Product segment revenues from our operations in the United States and 88.5% from the rest of the world.

S-2

Risk Factors

An investment in our common stock involves a high degree of risk. You should carefully consider and evaluate all of the information included and incorporated by reference in this prospectus, including the risk factors below, in the 2021 Form 10-K and the Q3 2022 Form 10-Q (each incorporated by reference into this prospectus supplement), and other filings we make with the SEC, which are incorporated by reference into this prospectus supplement. It is possible that our business, financial condition, liquidity or results of operations could be materially adversely affected by any of these risks.

The price of our common stock may fluctuate substantially, and your investment may decline in value. In addition, you will not be entitled to receive the next paid dividend.

The market price of our common stock may be highly volatile and may fluctuate substantially due to many factors, including:

•actual or anticipated fluctuations in our results of operations including as a result of seasonal variations in our Electricity segment-based revenues or variations from year-to-year in our Product segment-based revenues;

•variance in our financial performance from the expectations of market analysts;

•conditions and trends in the end markets we serve, and changes in the estimation of the size and growth rate of these markets;

•our ability to integrate acquisitions;

•announcements of significant contracts by us or our competitors;

•changes in our pricing policies or the pricing policies of our competitors;

•restatements of historical financial results and changes in financial forecasts;

•loss of one or more of our significant customers;

•changes in market valuation or earnings of our competitors;

•the trading volume of our common stock;

•the trading of our common stock on multiple trading markets, which takes place in different currencies and at different times; and

•general economic conditions.

In addition, the stock market in general, and the NYSE and the market for energy companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of particular companies affected. These broad market and industry factors may materially harm the market price of our common stock, regardless of our operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class-action litigation has often been instituted against that company. Such litigation, if instituted against us, could result in substantial costs and a diversion of management’s attention and resources, which could materially harm our business, financial condition, future results and cash flow. Furthermore, our next dividend payment is scheduled for November 30, 2022, and the record date for such payment is November 16, 2022. As a result, you will not be entitled to receive the next paid dividend.

Sales of a substantial number of shares of our common stock in the public market, or the perception that such sales could occur, could adversely affect the market price of our common stock. We are unable to predict the effect that such sales may have on the prevailing market price of the common stock.

Subject to certain exceptions described in the “Underwriting” section of this prospectus supplement, we, our directors and executive officers and the selling stockholder have agreed to enter into lock-up agreements with the underwriters of this offering pursuant to which we and they have agreed, or will agree, that we and they will not dispose of or hedge any shares of our common stock or any securities convertible into or exchangeable for shares of our common stock for a period of 60 days, 30 days, in the case of our directors and executive officers, and 180 days, in

S-3

the case of the selling stockholder, after the date of this prospectus supplement. BofA Securities, Inc. and J.P. Morgan Securities LLC may permit us or our directors and executive officers or the selling stockholder to sell shares prior to the end of the applicable lock-up period. Sales of a substantial number of such shares upon expiration of, or the perception that such sales may occur, or early release of the securities subject to, the lock-up agreements, could cause our stock price to fall or make it more difficult for you to sell common stock at a time and price that you deem appropriate. We may issue additional shares of common stock, which may dilute existing stockholders, including purchasers of the common stock offered hereby.

If securities or industry analysts publish inaccurate or unfavorable research, about our business, the price of our common stock and our trading volume could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. In the event securities or industry analysts downgrade our common stock or publish inaccurate or unfavorable research about our business, the price of our common stock would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, demand for our common stock could decrease, which might cause the price of our common stock and trading volume to decline.

S-4

Use of Proceeds

We will not receive any proceeds from the selling stockholder’s sale of the common stock described in this prospectus supplement and the accompanying base prospectus. Any common stock offered by the selling stockholder pursuant to this prospectus supplement and the accompanying base prospectus will be sold by the selling stockholder for its own account, and as such they will receive all of the net proceeds from the sale of these shares of common stock, including from any exercise by the underwriters of their option to purchase additional shares of common stock. See “Selling Stockholder.”

Pursuant to that certain Registration Rights Agreement, dated as of May 4, 2017 (as amended, the “Registration Rights Agreement”), we will bear all reasonable out-of-pocket costs, fees and expenses in connection with the selling stockholder’s resale of the common stock to be sold pursuant to this prospectus supplement, except for any underwriting fees, commissions and discounts, transfer taxes and legal fees incurred by the selling stockholder.

S-5

Selling Stockholder

The following table sets forth (i) the name of the selling stockholder, (ii) the number of shares of common stock beneficially owned by the selling stockholder, (iii) the number of shares of common stock to be offered by the selling stockholder pursuant to this prospectus supplement and (iv) the number of shares of common stock beneficially owned by the selling stockholder assuming all of the shares of common stock offered by the selling stockholder are sold in this offering. The percentage of shares of common stock beneficially owned is based on 56,085,468shares of common stock outstanding as of November 11, 2022.

We have prepared the table and the related notes based on information supplied to us by the selling stockholder on or prior to November16, 2022. We have not sought to verify such information.

Beneficial ownership has been determined under rules promulgated by the SEC. The information does not necessarily indicate beneficial ownership for any other purpose. Shares of common stock subject to currently exercisable and convertible securities currently convertible, or exercisable or convertible within 60 days after the date of this prospectus supplement, are deemed outstanding for purposes of computing the percentage beneficially owned by the person or entity holding such securities but are not deemed outstanding for purposes of computing the percentage beneficially owned by any other person or entity. For further information regarding the beneficial ownership of our shares of common stock and a description of the other material relationships between us and the selling stockholder, including the Governance Agreement, and certain other relationships which the selling stockholder has with us, including a Commercial Cooperation Agreement and the Registration Rights Agreement, see our Definitive Proxy Statement on Schedule 14A filed on April 18, 2022, including the information set forth under “Security Ownership of Certain Beneficial Owners and Management” and “Transactions with Related Persons.”

Material Relationships with the Selling Stockholder

For a description of certain relationships which the Selling Stockholder has had with us, please refer to the below disclosure as well as the information on the Governance Agreement, the Commercial Cooperation Agreement and the Registration Rights Agreement included in the section titled “Transactions with Related Persons” in our Definitive Proxy Statement on Schedule 14A filed on April 18, 2022.

This prospectus supplement was filed as a result of the exercise of demand registration rights by the selling stockholder pursuant to the Registration Rights Agreement. As set forth in the Registration Rights Agreement, we will bear all reasonable out-of-pocket costs, fees and expenses in connection with the selling stockholder’s resale of the common stock to be sold pursuant to this prospectus supplement, except for any underwriting fees, commissions and discounts, transfer taxes and legal fees incurred by the selling stockholder.

Governance Agreement

On May 4, 2017, we entered into a Governance Agreement with the selling stockholder (as amended, the “Governance Agreement”) in connection with an agreement between the selling stockholder, certain of our former stockholders, Isaac Angel, our current Chairman of the Board and former CEO, and Doron Blachar, our CEO, pursuant to which the selling stockholder agreed to purchase approximately, at such time, 22.1% of our shares of common stock for approximately $627 million. The Governance Agreement, which became effective on July 26, 2017 upon the closing of such transaction, provides the selling stockholder the right, for as long as the selling stockholder and its affiliates collectively hold at least 18% of the voting power of all of our outstanding voting securities, to nominate

S-6

three directors to our Board of Directors and jointly propose and nominate with us a director who is independent in accordance with the listing standards of the NYSE and SEC rules and regulations and who does not have, and within the three years prior to his or her becoming a director nominee has not had, any material relationship with the selling stockholder or its affiliates (the “Independent ORIX Director”). If the selling stockholder and its affiliates collectively hold less than 18% of the voting power of all of our outstanding voting securities but greater than or equal to 13% of the voting power of all of our outstanding voting securities, the selling stockholder has the right to nominate two directors to our Board of Directors and jointly propose and nominate the Independent ORIX Director with us. If the selling stockholder and its affiliates collectively hold less than 13% of the voting power of all of our outstanding voting securities but greater than or equal to 5% of the voting power of all of our outstanding voting securities, the selling stockholder will have the right to nominate one director to our Board of Directors, but will no longer have the right to jointly propose and nominate the Independent ORIX Director with us. If the selling stockholder holds less than 5% of the voting power of all of our outstanding voting securities, the selling stockholder does not have the right to nominate any directors to our Board of Directors. Currently, the selling stockholder’s three directors nominees, Karin Corfee, Mike Nikkel and Hidetake Takahashi, are members of our Board of Directors, and the Independent ORIX Director, Byron G. Wong, is a member of our Board of Directors.

After giving effect to this offering, the selling stockholder and its affiliates will collectively own 13.4% (or 12.4% if the underwriters exercise in full their option to purchase additional shares in this offering) of the voting power of all of our outstanding voting securities. Pursuant to the Governance Agreement, the selling stockholder is required to use its reasonable best efforts to cause one or two of the directors nominated by the selling stockholder (“Investor Directors”) to tender his or her resignations, unless a majority of the directors other than Investor Directors agree in writing that such Investor Directors shall not be required to resign. A majority of the members of our board of directors (other than Investor Directors) have agreed that no Investor Director will be required to resign following this offering. Accordingly, such directors will continue to serve on our board of directors at least until our 2023 annual meeting of stockholders.

Commercial Cooperation Agreement

On May 4, 2017, we also entered into a Commercial Cooperation Agreement with the selling stockholder (the “Commercial Cooperation Agreement”) in connection with the selling stockholder’s above-mentioned acquisition of common stock. Pursuant to the Commercial Cooperation Agreement, we received an exclusive right of first refusal to own, invest in, develop and operate new geothermal business opportunities outside the State of Japan sourced by or presented to the selling stockholder or its affiliates, subject to certain limitations, as well as an exclusive right to provide certain geological, engineering, procurement, construction, operational and/or management services, and be granted the option to acquire up to 49% ownership of all geothermal projects within the State of Japan that (i) are new geothermal business opportunities sourced by or presented to the selling stockholder or its affiliates, (ii) have an expected generating capacity of greater than 15 MW and (iii) are 100% owned by the selling stockholder or its affiliates, or with respect to which the selling stockholder or its affiliates have the ability to control all relevant decisions without being required to obtain any third party consent. The obligations of each party under the Commercial Cooperation Agreement are suspended during any period in which the selling stockholder holds less than 13% of the outstanding common stock. Accordingly, such obligations may be suspended following the closing of this offering.

Registration Rights Agreement

On May 4, 2017, we also entered into the Registration Rights Agreement with the selling stockholder. The Registration Rights Agreement provides, among other things, that the selling stockholder may require us to file up to two registration statements for public offerings of securities and may request that we effect a third public offering if we include securities for our own account in either of those first two registrations. The Registration Rights Agreement also permits the selling stockholder to require us to include securities held by the selling stockholder in registrations that we effect.

In connection with this offering, we and the selling stockholder amended the Registration Rights Agreement to, among other things, require us to file a shelf registration statement on Form S-3 or Form S-1, or a post-effective amendment or prospectus supplement to any then effective registration statement, to permit a public offering and sale of shares of common stock held by the selling stockholder. We are required to keep such shelf registration statement available for a period of three years after its initial effectiveness subject to our right to suspend its availability for up

S-7

to 120 days (and no more than 90 consecutive days) in any calendar year. The selling stockholder may, at any time, request an underwritten shelf takedown for shares of common stock held by the selling stockholder; provided, that the market value of such shares to be sold pursuant to the underwritten shelf takedown have a market value of at least $100 million at the time of the demand. The selling stockholder may exercise such demand rights twice (with this offering accounting for one such demand); provided that the selling stockholder will be entitled to exercise such demand registration rights a third time in the event we include shares for our own account in an offering pursuant to either of the first two demands. The selling stockholder has agreed with us, subject to limited exceptions, not to sell or transfer its shares for a period of 180 days following this offering and has agreed to waive its preemptive rights during that period.

We agreed to pay all fees and expenses in connection with the registration of the shares of common stock pursuant to the Registration Rights Agreement, except for any underwriting fees, commissions and discounts, transfer taxes and legal fees incurred by the selling stockholder.

S-8

Material U.S. Federal Tax Considerations for
Non-U.S. Holders of Our Common Stock

The following discussion is a summary of the material U.S. federal income tax consequences to Non-U.S. Holders (as defined below) of the ownership and disposition of our common stock purchased in accordance with this prospectus supplement, but does not purport to be a complete analysis of all potential tax consequences. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local, or non-U.S. tax laws are not discussed. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended, or the Code, Treasury Regulations promulgated thereunder, judicial decisions and published rulings and administrative pronouncements of the U.S. Internal Revenue Service, or the IRS, in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a Non-U.S. Holder of our common stock. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership and disposition of our common stock.

This discussion is limited to Non-U.S. Holders that hold our common stock as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a Non-U.S. Holder’s particular circumstances, including the impact of the Medicare contribution tax on net investment income or any alternative minimum tax consequences. In addition, it does not address consequences relevant to Non-U.S. Holders subject to special rules, including, without limitation:

•U.S. expatriates and former citizens or long-term residents of the United States;

•persons holding our common stock as part of a straddle, or other risk reduction strategy or as part of a conversion transaction or other integrated investment;

•persons subject to special tax accounting rules as a result of any item of gross income with respect to our common stock being taken into account in an applicable financial statement;

•banks, insurance companies and other financial institutions;

•brokers, dealers, or traders in securities;

•“controlled foreign corporations,” “passive foreign investment companies,” and corporations that accumulate earnings to avoid U.S. federal income tax;

•partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes (and investors therein);

•tax-exempt organizations or governmental organizations;

•persons deemed to sell our common stock under the constructive sale provisions of the Code;

•persons who hold or receive our common stock pursuant to the exercise of any employee stock option or otherwise as compensation;

•persons that own or have owned, or are deemed to own or to have owned, more than 5% of our common stock;

•tax-qualified retirement plans; and

•“qualified foreign pension funds” as defined in Section 897(l)(2) of the Code and entities all of the interests of which are held by qualified foreign pension funds.

If an entity (or arrangement) treated as a partnership for U.S. federal income tax purposes holds our common stock, the tax treatment of a partner or beneficial owner of the entity will depend on the status of the partner or beneficial owner, the activities of the entity and certain determinations made at the partner or beneficial owner level. Accordingly, entities treated as partnerships for U.S. federal income tax purposes holding our common stock and the partners or beneficial owners in such entities should consult their tax advisors regarding the U.S. federal income tax consequences to them.

S-9

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Definition of a Non-U.S. Holder

For purposes of this discussion, a “Non-U.S. Holder” is any beneficial owner of our common stock that is neither a “U.S. Holder” nor an entity (or arrangement) treated as a partnership for U.S. federal income tax purposes. A U.S. Holder is any person that, for U.S. federal income tax purposes, is or is treated as any of the following:

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

•an entity created or organized under the laws of the United States, any state thereof, or the District of Columbia that is classified as a corporation for U.S. federal income tax purposes;

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

•a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code), or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

Distributions

Distributions of cash or other property on our common stock will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. If a distribution exceeds our current and accumulated earnings and profits, the excess will not be treated as a dividend for U.S. federal income tax purposes. Rather, the excess will first constitute a return of capital and be applied against and reduce a Non-U.S. Holder’s adjusted tax basis in its common stock, but not below zero. Any further excess will be treated as capital gain and will be treated as described below under “— Sale or Other Taxable Disposition.” Any such distributions will also be subject to the discussions below under the sections titled “Information Reporting and Backup Withholding” and “Additional Withholding Tax on Payments Made to Foreign Accounts.”

Except as described below with respect to effectively connected dividends and subject to the discussions below of backup withholding and Sections 1471 to 1474 of the Code (such Sections and related Treasury Regulations commonly referred to as the Foreign Account Tax Compliance Act, or FATCA), dividends paid to a Non-U.S. Holder of our common stock will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the Non-U.S. Holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). If a Non-U.S. Holder holds the stock through a financial institution or other intermediary, the Non-U.S. Holder will be required to provide appropriate documentation to the intermediary, which then will be required to provide appropriate documentation to the applicable withholding agent, either directly or through other intermediaries. A Non-U.S. Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States.

S-10

Any such effectively connected dividends will be subject to U.S. federal income tax generally in the same manner as if the Non-U.S. Holder were a U.S. person and be subject to U.S. federal income tax on a net income basis at the regular U.S. federal income tax rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on its effectively connected earnings and profits for the taxable year that are attributable to such dividends, as adjusted for certain items. Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules or rates.

Sale or Other Taxable Disposition

Subject to the discussions below regarding FATCA and backup withholding (see “— Information Reporting and Backup Withholding” and “— Additional Withholding Tax on Payments Made to Foreign Accounts”), a Non-U.S. Holder generally will not be subject to U.S. federal income tax or withholding tax on any gain realized upon the sale or other taxable disposition of our common stock unless:

•the gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such gain is attributable);

•the gain is recognized by a Non-U.S. Holder that is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met; or

•our common stock constitutes a U.S. real property interest, or USRPI (as defined under Section 897(c) of the Code), by reason of our status as a U.S. real property holding corporation, or USRPHC (as defined under Section 897(c)(2)), for U.S. federal income tax purposes, at any time within the five-year period preceding the disposition or, if shorter, the Non-U.S. Holder’s holding period.

Gain described in the first bullet point above generally will be subject to U.S. federal income tax in the same manner as if the Non-U.S. Holder were a U.S. person and be taxed under regular U.S. federal income tax rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on a portion of its effectively connected earnings and profits for the taxable year that are attributable to such gain, as adjusted for certain items.

Gain described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, while we believe that we are not a USRPHC, we have not yet made a formal determination on our status as a USRPHC. Generally, a domestic corporation is a USRPHC if the fair market value of its USRPIs equals or exceeds 50% of the aggregate fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business. Because the determination of whether we are a USRPHC depends on the fair market value of our USRPIs relative to the fair market value of our non-U.S. real property interests and our other business assets, there can be no assurance that we currently are not a USRPHC or that we will not become a USRPHC in the future. Even if we are or were to become a USRPHC, however, our common stock will not be treated as a USRPI with respect to a Non-U.S. Holder if our common stock is “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market (such as the New York Stock Exchange), and such Non-U.S. Holder owned, actually or constructively, 5% or less of our common stock throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition of, or the Non-U.S. Holder’s holding period for, our common stock. We expect our common stock to be regularly traded on an established securities market. However, if we are a USRPHC and our common stock is not considered regularly traded on an established securities market at any time during the calendar year in which the sale or other taxable disposition occurs, (1) such Non-U.S. Holder generally will be taxed on its net gain derived from the disposition at the U.S. federal income tax rates applicable to United States persons (as defined in the Code) and (2) a buyer of our common stock from such Non-U.S. holder may be required to withhold U.S. federal income tax at a rate of 15% of the amount realized upon such disposition.

S-11

Non-U.S. Holders should consult their tax advisors regarding the application of the above to their particular situation, including the potential application of any available income tax treaty that may provide for different rules.

Information Reporting and Backup Withholding

Payments of dividends on our common stock will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a U.S. person and the holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E, W-8ECI, or W-8EXP, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any dividends on our common stock paid to the Non-U.S. Holder, regardless of whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of our common stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting, if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a U.S. person, or the holder otherwise establishes an exemption. Proceeds of a disposition of our common stock conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established or organized.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may 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 timely furnished to the IRS.

Additional Withholding Tax on Payments Made to Foreign Accounts

Withholding taxes may be imposed under FATCA on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on, or, subject to the proposed Treasury Regulations discussed below, gross proceeds from the sale or other disposition of, our common stock paid to a “foreign financial institution” (as defined by the Code to include, in addition to banks and traditional financial institutions, entities such as investment funds and certain holding companies) or a “non-financial foreign entity” (as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence, reporting and withholding obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence, reporting and withholding requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States-owned foreign entities” (each as defined in the Code), annually report certain information about such accounts and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Accordingly, the entity through which our common stock is held will affect the determination of whether such withholding is required. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our common stock. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of stock on or after January 1, 2019, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued.

The FATCA withholding tax will apply to all withholdable payments without regard to whether the beneficial owner of the payment would otherwise be entitled to an exemption from imposition of withholding tax pursuant to an applicable tax treaty with the United States or U.S. domestic law. Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our common stock.

Underwriting

The selling stockholder is offering the shares of common stock described in this prospectus through a number of underwriters. BofA Securities, Inc. and J.P. Morgan Securities LLC are acting as representatives of the underwriters. We and the selling stockholder have entered into an underwriting agreement with the underwriters. Subject to the terms and conditions of the underwriting agreement, the selling stockholder has agreed to sell to the underwriters, and each underwriter has severally agreed to purchase, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus, the number of shares of common stock listed next to its name in the following table:

Name	Number of Shares
BofA Securities, Inc.
J.P. Morgan Securities LLC
Total	3,500,000

The underwriters are committed to purchase all the common shares offered by the selling stockholder if they purchase any shares. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters propose to offer the common shares directly to the public at the initial public offering price set forth on the cover page of this prospectus and to certain dealers at that price less a concession not in excess of $per share. Any such dealers may resell shares to certain other brokers or dealers at a discount of up to $   per share from the initial public offering price. After the initial offering of the shares to the public, if all of the common shares are not sold at the initial public offering price, the underwriters may change the offering price and the other selling terms. Sales of any shares made outside of the United States may be made by affiliates of the underwriters.

The underwriters have an option to buy up to 525,000 additional shares of common stock from the selling stockholder to cover sales of shares by the underwriters which exceed the number of shares specified in the table above. The underwriters have 30 days from the date of this prospectus to exercise this option to purchase additional shares. If any shares are purchased with this option to purchase additional shares, the underwriters will purchase shares in approximately the same proportion as shown in the table above. If any additional shares of common stock are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares are being offered.

The underwriting fee is equal to the public offering price per share of common stock less the amount paid by the underwriters to us per share of common stock. The underwriting fee is $per share. The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares.

	Without option to purchase additional shares exercise	With full option to purchase additional shares exercise
Per Share	$	$
Total	$	$

We estimate that the total expenses of this offering payable by us, including registration, filing and listing fees, printing fees and legal and accounting expenses, but excluding the underwriting discounts and commissions, will be approximately $500,000.

A prospectus in electronic format may be made available on the web sites maintained by one or more underwriters, or selling group members, if any, participating in the offering. The underwriters may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters and selling group members that may make Internet distributions on the same basis as other allocations.

S-13

We have agreed that we will not (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, or submit to, or file with, the Securities and Exchange Commission a registration statement under the Securities Act relating to, any shares of our common stock or securities convertible into or exercisable or exchangeable for any shares of our common stock, or publicly disclose the intention to make any offer, sale, pledge, loan, disposition or filing, or (ii) enter into any swap or other arrangement that transfers all or a portion of the economic consequences associated with the ownership of any shares of common stock or any such other securities (regardless of whether any of these transactions are to be settled by the delivery of shares of common stock or such other securities, in cash or otherwise), in each case without the prior written consent of BofA Securities, Inc. and J.P. Morgan Securities LLC for a period of 60 days after the date of this prospectus, other than the shares of our common stock to be sold in this offering.

The restrictions on our actions, as described above, do not apply to certain transactions, including (i) the issuance of shares of common stock or securities convertible into or exercisable for shares of our common stock pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options (including net exercise) or the settlement of RSUs (including net settlement), in each case outstanding on the date of the underwriting agreement and described in this prospectus; (ii) grants of stock options, stock awards, restricted stock, RSUs, or other equity awards and the issuance of shares of our common stock or securities convertible into or exercisable or exchangeable for shares of our common stock (whether upon the exercise of stock options or otherwise) to our employees, officers, directors, advisors, or consultants pursuant to the terms of an equity compensation plan in effect as of the closing of this offering and described in this prospectus, provided that such recipients enter into a lock-up agreement with the underwriters; or (iii) the issuance of our common stock or any securities convertible into or exercisable or exchangeable for our common stock in connection with the acquisition by us of the securities, businesses, property or other assets of another person or entity or in connection with strategic partnering transactions; provided that the aggregate number of shares of common stock does not exceed 10% of the outstanding shares of our common stock immediately following the issuance and sale of the shares as part of this offering and any such recipient shall enter into a lock-up agreement with the Underwriters.

Our directors, executive officers and the selling stockholder (such persons, the “lock-up parties”), have entered into lock-up agreements with the underwriters prior to the commencement of this offering pursuant to which each lock-up party, with limited exceptions, for a period of 30 days in the case of our directors and executive officers and 180 days in the case of the selling stockholder after the date of this prospectus (such period, the “restricted period”), may not (and may not cause any of their direct or indirect affiliates to), without the prior written consent of BofA Securities, Inc. and J.P. Morgan Securities LLC, (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for our common stock (including, without limitation, common stock or such other securities which may be deemed to be beneficially owned by such lock-up parties in accordance with the rules and regulations of the SEC and securities which may be issued upon exercise of a stock option or warrant (collectively with the common stock, the “lock-up securities”)), (2) enter into any hedging, swap or other agreement or transaction that transfers, in whole or in part, any of the economic consequences of ownership of the lock-up securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of lock-up securities, in cash or otherwise, (3) make any demand for, or exercise any right with respect to, the registration of any lock-up securities, or (4) publicly disclose the intention to do any of the foregoing. Such persons or entities have further acknowledged that these undertakings preclude them from engaging in any hedging or other transactions or arrangements (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap or any other derivative transaction or instrument, however described or defined) designed or intended, or which could reasonably be expected to lead to or result in, a sale or disposition or transfer (by any person or entity, whether or not a signatory to such agreement) of any economic consequences of ownership, in whole or in part, directly or indirectly, of any lock-up securities, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of lock-up securities, in cash or otherwise.

The restrictions described in the immediately preceding paragraph and contained in the lock-up agreements between the underwriters and the lock-up parties do not apply, subject in certain cases to various conditions, to certain transactions, including (a) transfers of lock-up securities: (i) as bona fide gifts, or for bona fide estate planning purposes, (ii) by will or intestacy, (iii) to any trust for the direct or indirect benefit of the lock-up party or any immediate family member, (iv) to a partnership, limited liability company or other entity of which the lock-up party or

S-14

its immediate family members are the legal and beneficial owner of all of the outstanding equity securities or similar interests, (v) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (i) through (iv), (vi) in the case of a corporation, partnership, limited liability company, trust or other business entity, (A) to another corporation, partnership, limited liability company, trust or other business entity that is an affiliate of the lock-up party, or to any investment fund or other entity controlling, controlled by, managing or managed by or under common control with the lock-up party or its affiliates or (B) as part of a distribution to limited partners, members, stockholders or other equityholders of the lock-up party; (vii) by operation of law, (viii) to us from an employee upon death, disability or termination of employment of such employee, (ix) as part of a sale of lock-up securities acquired in open market transactions after the completion of this offering, (x) to us in connection with the vesting, settlement or exercise of restricted stock units, stock appreciation rights, options, warrants or other rights to purchase shares of our common stock (including “net” or “cashless” exercise), including for the payment of exercise price and tax and remittance payments, or (xi) pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction approved by our board of directors and made to all shareholders involving a change in control, provided that if such transaction is not completed, all such lock-up securities would remain subject to the restrictions in the immediately preceding paragraph; (b) exercise of the options, stock appreciation rights, settlement of RSUs or other equity awards, or the exercise of warrants granted pursuant to plans described in this prospectus, provided that any lock-up securities received upon such exercise, vesting or settlement would be subject to restrictions similar to those in the immediately preceding paragraph; (c) the conversion of outstanding preferred stock, warrants to acquire preferred stock, or convertible securities into shares of our common stock or warrants to acquire shares of our common stock, provided that any common stock or warrant received upon such conversion would be subject to restrictions similar to those in the immediately preceding paragraph; (d) the establishment by lock-up parties of trading plans under Rule 10b5-1 under the Exchange Act, provided that such plan does not provide for the transfer of lock-up securities during the restricted period; and (e) the sale of our common stock pursuant to the terms of the underwriting agreement.

BofA Securities, Inc. and J.P. Morgan Securities LLC, in their sole discretion, may release the securities subject to any of the lock-up agreements with the underwriters described above, in whole or in part at any time. Any such release by the underwriters will not constitute a release under the lock-up agreement entered into by the selling stockholder with us. See “The Selling Stockholder — Registration Rights Agreement.”

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933.

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing and selling shares of common stock in the open market for the purpose of preventing or retarding a decline in the market price of the common stock while this offering is in progress. These stabilizing transactions may include making short sales of common stock, which involves the sale by the underwriters of a greater number of shares of common stock than they are required to purchase in this offering, and purchasing shares of common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to purchase additional shares referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional shares, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the option to purchase additional shares. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M of the Securities Act of 1933, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the common stock, including the imposition of penalty bids. This means that if the representatives of the underwriters purchase common stock in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

S-15

These activities may have the effect of raising or maintaining the market price of the common stock or preventing or retarding a decline in the market price of the common stock, and, as a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on the NYSE, in the over-the-counter market or otherwise.

Other than in the United States, no action has been taken by us or the underwriters that would permit a public offering of the securities offered by this prospectus in any jurisdiction where action for that purpose is required. The securities offered by this prospectus may not be offered or sold, directly or indirectly, nor may this prospectus or any other offering material or advertisements in connection with the offer and sale of any such securities be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons into whose possession this prospectus comes are advised to inform themselves about and to observe any restrictions relating to the offering and the distribution of this prospectus. This prospectus does not constitute an offer to sell or a solicitation of an offer to buy any securities offered by this prospectus in any jurisdiction in which such an offer or a solicitation is unlawful.

Certain of the underwriters and their affiliates have provided in the past to us and our affiliates and may provide from time to time in the future certain commercial banking, financial advisory, investment banking and other services for us and such affiliates in the ordinary course of their business, for which they have received and may continue to receive customary fees and commissions. In addition, from time to time, certain of the underwriters and their affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities or loans, and may do so in the future.

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.

10

If we denominate the purchase price of any of the debt securities in a foreign currency or currencies or a foreign currency unit or units, or if the principal of and any premium and interest on any series of debt securities is payable in a foreign currency or currencies or a foreign currency unit or units, we will provide you with information on the restrictions, elections, general tax considerations, specific terms and other information with respect to that issue of debt securities and such foreign currency or currencies or foreign currency unit or units in the applicable prospectus supplement.

Form, Transfer and Exchange

Each debt security will be represented by either one or more global securities registered in the name of The Depository Trust Company (the “Depositary”), or a nominee of the Depositary (we will refer to any debt security represented by a global debt security as a “book-entry debt security”), or a certificate issued in definitive registered form (we will refer to any debt security represented by a certificated security as a “certificated debt security”) as set forth in the applicable prospectus supplement. Except as set forth under the heading “Global Debt Securities and Book-Entry System” below, book-entry debt securities will not be issuable in certificated form.

Global Debt Securities and Book-Entry System. Each global debt security representing book-entry debt securities will be deposited with, or on behalf of, the Depositary, and registered in the name of the Depositary or a nominee of the Depositary. Unless and until it is exchanged for individual certificates evidencing securities under the limited circumstances described in the indenture, a global debt security may not be transferred except as a whole by the depositary to its nominee or by the nominee to the depositary, or by the depositary or its nominee to a successor depositary or to a nominee of the successor depositary.

Depositary holds securities that its participants deposit with Depositary. Depositary also facilitates the settlement among its participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates. “Direct participants” in Depositary include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and other organizations. Access to the Depositary system is also available to others (which we sometimes refer to as indirect participants) that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to Depositary and its participants are on file with the SEC.

So long as the debt securities are in book-entry form, the beneficial owners of such debt securities will receive payments and may transfer debt securities only through the facilities of the Depositary and its direct and indirect participants. We will maintain an office or agency in the location specified in the prospectus supplement for the applicable securities, where notices and demands in respect of the securities and the indenture may be delivered to us and where certificated debt securities may be surrendered for payment, registration of transfer or exchange. We will make payments on book-entry debt securities to the Depositary or its nominee, as the registered owner of such securities, by wire transfer of immediately available funds.

Certificated Debt Securities. Each beneficial owner of certificated debt securities may transfer or exchange such debt securities at any office we maintain for this purpose in accordance with the terms of the indenture. No service charge will be made for any transfer or exchange of certificated debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange.

Each beneficial owner of certificated debt securities may effect the transfer of such debt securities and the right to receive the principal of, premium and interest on certificated debt securities only by surrendering the certificate representing those certificated debt securities and either reissuance by us or the trustee of the certificate to the new holder or the issuance by us or the trustee of a new certificate to the new holder.

If the debt securities are issued in definitive certificated form under the limited circumstances described in the indenture, we will have the option of making payments by check mailed to the addresses of the persons entitled to payment or by wire transfer to bank accounts in the United States designated in writing to the applicable trustee or other designated party at least 15 days before the applicable payment date by the persons entitled to payment, unless a shorter period is satisfactory to the applicable trustee or other designated party.

11

Covenants

We will set forth in the applicable prospectus supplement any restrictive covenants applicable to any issue of debt securities, including the payment of principal, premium, if any, and interest on such debt securities. The indenture will not limit us from incurring or issuing other unsecured or secured debt and, unless otherwise indicated in the applicable prospectus supplement, the indenture will not contain any financial covenants.

No Protection in the Event of a Change of Control

Unless we state otherwise in the applicable prospectus supplement, the debt securities will not contain any provisions which may afford holders of the debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control) which could adversely affect holders of debt securities.

Conversion or Exchange Rights

We will set forth in the applicable prospectus supplement or free writing prospectus the terms on which a series of debt securities may be convertible into or exchangeable for our common stock, our preferred stock or other securities (including securities of a third-party). 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 shares of our common stock, our preferred stock or other securities (including securities of a third-party) that the holders of the series of debt securities receive would be subject to adjustment.

Consolidation, Merger and Sale of Assets

Unless otherwise indicated in the applicable prospectus supplement, Ormat may not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of our properties and assets to, any person (a “successor person”) unless:

•we are the surviving corporation or the successor person (if other than Ormat) is a corporation organized and validly existing under the laws of any U.S. domestic jurisdiction and expressly assumes our obligations on the debt securities and under the indenture; and

•immediately after giving effect to the transaction, no Default (as defined below) or Event of Default, shall have occurred and be continuing.

Notwithstanding the above, any subsidiary of Ormat may consolidate with, merge into or transfer all or part of its properties to Ormat or to any other person.

Events of Default

“Event of Default” means with respect to any series of debt securities, any of the following:

•default in the payment of any interest upon any debt security of that series when it becomes due and payable, and continuance of such default for a period of 30 days (unless the entire amount of the payment is deposited by us with the trustee or with a paying agent prior to the expiration of the 30-day period);

•default in the payment of principal of any security of that series at its maturity;

•default in the performance or breach of any other covenant or warranty by us in the indenture (other than a covenant or warranty that has been included in the indenture solely for the benefit of a series of debt securities other than that series), which default continues uncured for a period of 60 days after we receive written notice from the trustee or we and the trustee receive written notice from the holders of not less than 25% in principal amount of the outstanding debt securities of that series as provided in the indenture;

•certain voluntary or involuntary events of bankruptcy, insolvency or reorganization of Ormat; and

•any other Event of Default provided with respect to debt securities of that series that is described in the applicable prospectus supplement.

“Default” means any event which is, or after notice or passage of time or both would be, an Event of Default.

12

No Event of Default with respect to a particular series of debt securities (except as to certain events of bankruptcy, insolvency or reorganization) necessarily constitutes an Event of Default with respect to any other series of debt securities. The occurrence of certain Events of Default or an acceleration under the indenture may constitute an event of default under certain indebtedness of ours or our subsidiaries outstanding from time to time.

We will provide the trustee written notice of any Default or Event of Default within 30 days of becoming aware of the occurrence of such Default or Event of Default, which notice will describe in reasonable detail the status of such Default or Event of Default and what action we are taking or propose to take in respect thereof.

If an Event of Default with respect to debt securities of any series at the time outstanding occurs and is continuing, then the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal of (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) and accrued and unpaid interest, if any, on all debt securities of that series. In the case of an Event of Default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) 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 a declaration of acceleration with respect to debt securities of any series has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration if all Events of Default, other than the non-payment of accelerated principal and interest, if any, with respect to debt securities of that series, have been cured or waived as provided in the indenture. We refer to the applicable prospectus supplement relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an Event of Default.

The indenture will provide that the trustee may refuse to perform any duty or exercise any of its rights or powers under the indenture unless the trustee receives indemnity satisfactory to it against any cost, liability or expense which might be incurred by it in performing such duty or exercising such right or power. Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any 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 conferred on the trustee 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, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

•that holder has previously given to the trustee written notice of a continuing Event of Default with respect to debt securities of that series; and

•the holders of not less than 25% in principal amount of the outstanding debt securities of that series have made written request, and offered indemnity or security satisfactory to the trustee, to the trustee to institute the proceeding as trustee, and the trustee has not received from the holders of not less than a majority in principal amount of the outstanding debt securities of that series a direction inconsistent with that request and has failed to institute the proceeding within 60 days.

Notwithstanding any other provision in the indenture, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, premium and any interest on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment.

The indenture will require us, within 120 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture. If a Default or Event of Default occurs and is continuing with respect to the securities of any series and if it is known to a responsible officer of the trustee, the trustee shall mail to each Securityholder of the securities of that series notice of a Default or Event of Default within 90 days after it occurs or, if later, after a responsible officer of the trustee has knowledge of such Default or Event of Default. The indenture will provide that the trustee may withhold notice to the holders of debt securities of any series of any Default or Event of Default (except in payment on any debt securities of that series) with respect to debt securities of that series if the trustee determines in good faith that withholding notice is in the interest of the holders of those debt securities.

13

Modification and Waiver

We and the trustee may modify, amend or supplement the indenture or the debt securities of any series without the consent of any holder of any debt security:

•to cure any ambiguity, defect or inconsistency;

•to comply with covenants in the indenture described under the heading “Successors”;

•to provide for uncertificated securities in addition to or in place of certificated securities;

•to add guarantees with respect to debt securities of any series or secure debt securities of any series;

•to surrender any of our rights or powers under the indenture;

•to add covenants or events of default for the benefit of the holders of debt securities of any series;

•to comply with the applicable procedures of the applicable depositary;

•to make any change that does not adversely affect the rights of any holder of debt securities;

•to provide for the issuance of and establish the form and terms and conditions of debt securities of any series as permitted by the indenture;

•to effect the appointment of a successor trustee with respect to the debt securities of any series and to add to or change any of the provisions of the indenture to provide for or facilitate administration by more than one trustee; or

•to comply with requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act.

We may also modify and amend the indenture with the consent of the holders of a majority in principal amount of the outstanding debt securities of each series affected by the modifications or amendments (with the securities of each series voting as a class). We may not make any modification or amendment without the consent of the holders of each affected debt security then outstanding if that amendment will:

•reduce the amount of debt securities whose holders must consent to an amendment, supplement or waiver;

•reduce the rate of or extend the time for payment of interest (including default interest) on any debt security;

•reduce the principal of or premium on or change the fixed maturity of any debt security or reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation with respect to any series of debt securities;

•reduce the principal amount of discount securities payable upon acceleration of maturity;

•waive a default in the payment of the principal of, premium or interest on any debt security (except a rescission of acceleration of the debt securities of any series by the holders of a majority in aggregate principal amount of the then outstanding debt securities of that series and a waiver of the payment default that resulted from such acceleration);

•make the principal of or premium or interest on any debt security payable in currency other than that stated in the debt security;

•make any change to certain provisions of the indenture relating to, among other things, the right of holders of debt securities to receive payment of the principal of, premium and interest on those debt securities and to institute suit for the enforcement of any such payment and to waivers or amendments; or

•waive a redemption payment with respect to any debt security.

14

Except for certain specified provisions, the holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive our compliance with provisions of the indenture. The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all the debt securities of such series waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of, premium or any interest on any debt security of that series; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration.

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance.The indenture will provide that, unless otherwise provided by the terms of the applicable series of debt securities, we will be discharged from any and all obligations in respect of the debt securities of any series (subject to certain exceptions) upon the irrevocable deposit with the trustee, in trust, of money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. Dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money or U.S. government obligations in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities.

This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel stating that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable United States federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the holders of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred.

Defeasance of Certain Covenants.The indenture will provide that, unless otherwise provided by the terms of the applicable series of debt securities, upon compliance with certain conditions:

•we may omit to comply with the covenant described under the heading “When Company May Merge, Etc.” and certain other covenants set forth in the indenture, as well as any additional covenants which may be set forth in the applicable prospectus supplement; and

•any omission to comply with those covenants will not constitute a Default or an Event of Default with respect to the debt securities of that series (“covenant defeasance”).

The conditions include:

•depositing with the trustee money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. Dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal of, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities; and

•delivering to the trustee an opinion of counsel to the effect that the holders of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of such covenant defeasance and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred.

15

In the event covenant defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, rehabilitation and insolvency events) described under “Events of Default” will no longer constitute an Event of Default with respect to the applicable series of debt securities.

No Personal Liability of Directors, Officers, Employees or Stockholders

None of our past, present or future directors, officers, employees or stockholders, as such, will have any liability for any of our obligations under the debt securities or the indenture or for any claim based on, or in respect or by reason of, such obligations or their creation. By accepting a debt security, each holder waives and releases all such liability. This waiver and release is part of the consideration for the issue of the debt securities. However, this waiver and release may not be effective to waive liabilities under U.S. federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

Governing Law

The indenture and the debt securities, including any claim or controversy arising out of or relating to the indenture or the securities, will be governed by the laws of the State of New York.

The indenture will provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to the indenture, the debt securities or the transactions contemplated thereby.

The indenture will provide that any legal suit, action or proceeding arising out of or based upon the indenture or the transactions contemplated thereby may be instituted in the federal courts of the United States of America located in the City of New York or the courts of the State of New York in each case located in the City of New York, and we, the trustee and the holder of the debt securities (by their acceptance of the debt securities) irrevocably submit to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. The indenture will further provide that service of any process, summons, notice or document by mail (to the extent allowed under any applicable statute or rule of court) to such party’s address set forth in the indenture will be effective service of process for any suit, action or other proceeding brought in any such court. The indenture will further provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the courts specified above and irrevocably and unconditionally waive and agree not to plead or claim any such suit, action or other proceeding has been brought in an inconvenient forum.

16

DESCRIPTION OF WARRANTS

We may elect to offer warrants from time to time in one or more series. The following description summarizes the general terms and provisions of the warrants we may offer pursuant to this prospectus that are common to all series. The specific terms relating to any series of our warrants that we offer will be described in a prospectus supplement, which you should read. Because the terms of specific series of warrants offered may differ from the general information that we have provided below, you should rely on information in the applicable prospectus supplement that contradicts any information below. The summary below is not complete and is subject to, and qualified in its entirety by reference to, the terms and provisions of the applicable warrant agreement relating to each series of warrants, which will be in the form filed as an exhibit to or incorporated by reference in the registration statement of which this prospectus is a part at or prior to the time of the issuance of such series of warrants.

General

We may issue warrants to purchase common stock, preferred stock, depositary shares, debt securities or any combination thereof, which we refer to in this prospectus, collectively, as the “underlying warrant securities.” The warrants may be issued independently or together with any series of underlying warrant securities and may be attached or separate from the underlying warrant securities. Each series of warrants will be issued pursuant to a separate form of warrant and may be issued pursuant to a separate warrant agreement to be entered into between us and a warrant agent. Any warrant agent will act solely as our agent in connection with the warrants of such series and will not assume any obligation or relationship of agency for or with holders or beneficial owners of warrants.

The applicable prospectus supplement will describe the terms of any series of warrants in respect of which this prospectus is being delivered, including the following:

•the title of the warrants;

•the aggregate number of warrants;

•the price or prices at which the warrants will be issued;

•the currency or currencies in which the price of the warrants may be payable;

•the designation and terms of the underlying warrant securities purchasable upon exercise of the warrants and the number of such underlying warrant securities issuable upon exercise of the warrants;

•the price at which and the currency or currencies, including composite currencies, in which the underlying warrant securities purchasable upon exercise of the warrants may be purchased;

•the date on which the right to exercise the warrants will commence and the date on which that right will expire (subject to any extension);

•whether the warrants will be issued in registered form or bearer form;

•if applicable, the minimum or maximum amount of the warrants which may be exercised at any one time;

•if applicable, the designation and terms of the underlying warrant securities with which the warrants are issued and the number of the warrants issued with each underlying warrant security;

•if applicable, the date on and after which the warrants and the related underlying warrant securities will be separately transferable;

•information with respect to book-entry procedures, if any;

•if applicable, a discussion of the material United States federal income tax considerations applicable to the issuance or exercise of the warrants; and

•any other terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants.

Amendments and Supplements to Warrant Agreement

The warrant agreement for a series of warrants, if applicable, may be amended or supplemented without the consent of the holders of the warrants issued thereunder to effect changes that are not inconsistent with the provisions of the warrants and that do not adversely affect the interests of the holders of the warrants.

17

DESCRIPTION OF UNITS

The following description, together with the additional information we include in any applicable prospectus supplements, summarizes the material terms and provisions of the units that we may offer under this prospectus. Units may be offered independently or together with common stock, preferred stock, debt securities, and warrants offered by any prospectus supplement, and may be attached to or separate from those securities. While the terms we have summarized below will generally apply to any future units that we may offer under this prospectus, we will describe the particular terms of any series of units that we may offer in more detail in the applicable prospectus supplement. The terms of any units offered under a prospectus supplement may differ from the terms described below.

We will incorporate by reference into the registration statement, of which this prospectus is a part, the form of unit agreement, including a form of unit certificate, if any, that describes the terms of the series of units we are offering before the issuance of the related series of units. The following summaries of material provisions of the units and the unit agreements are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement applicable to a particular series of units. We urge you to read the applicable prospectus supplements related to the units that we sell under this prospectus, as well as the complete unit agreements that contain the terms of the units.

General

We may issue units consisting of common stock, preferred stock, debt securities, and/or 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.

We will describe in the applicable prospectus supplement the terms of the series of units, including the following:

•the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

•any provisions of the governing unit agreement that differ from those described below; and

•any provisions for the issuance, payment, settlement, transfer, or exchange of the units or of the securities comprising the units

The provisions described in this section, as well as those described in the sections entitled “Description of Common Stock and Preferred Stock,” “Description of Debt Securities,” and “Description of Warrants,” will apply to each unit and to any common stock, preferred stock, debt security, or warrant included in each unit, respectively.

Issuance in Series

We may issue units in such amounts and in such numerous distinct series as we determine.

Enforceability of Rights by Holders of Units

Each unit agent will act solely as our agent under the applicable unit agreement and will not assume any obligation or relationship of agency or trust with any holder of any unit. A single bank or trust company may act as unit agent for more than one series of units. A unit agent will have no duty or responsibility in case of any default by us under the applicable unit agreement or unit, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a unit may, without the consent of the related unit agent or the holder of any other unit, enforce by appropriate legal action its rights as holder under any security included in the unit.

Title

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

18

GLOBAL SECURITIES

Book-Entry, Delivery and Form

Unless we indicate differently in a prospectus supplement, the securities initially will be issued in book-entry form and represented by one or more global securities. The global securities will be deposited with, or on behalf of, The Depository Trust Company, New York, New York, as depositary, or DTC, and registered in the name of Cede & Co., the nominee of DTC. Unless and until it is exchanged for individual certificates evidencing securities under the limited circumstances described below, a global security may not be transferred except as a whole by the depositary to its nominee or by the nominee to the depositary, or by the depositary or its nominee to a successor depositary or to a nominee of the successor depositary.

DTC has advised us that it is:

•a limited-purpose trust company organized under the New York Banking Law;

•a “banking organization” within the meaning of the New York Banking Law;

•a member of the Federal Reserve System;

•a “clearing corporation” within the meaning of the New York Uniform Commercial Code; and

•a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended, or Exchange Act.

DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among its participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates. “Direct participants” in DTC include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation, or DTCC. DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others, which we sometimes refer to as indirect participants, that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of securities under the DTC system must be made by or through direct participants, which will receive a credit for the securities on DTC’s records. The ownership interest of the actual purchaser of a security, which we sometimes refer to as a beneficial owner, is in turn recorded on the direct and indirect participants’ records. Beneficial owners of securities will not receive written confirmation from DTC of their purchases. However, beneficial owners are expected to receive written confirmations providing details of their transactions, as well as periodic statements of their holdings, from the direct or indirect participants through which they purchased securities. Transfers of ownership interests in global securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the global securities, except under the limited circumstances described below.

To facilitate subsequent transfers, all global securities deposited by direct participants with DTC will be registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other nominee will not change the beneficial ownership of the securities. DTC has no knowledge of the actual beneficial owners of the securities. DTC’s records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The participants are responsible for keeping account of their holdings on behalf of their customers.

So long as the securities are in book-entry form, you will receive payments and may transfer securities only through the facilities of the depositary and its direct and indirect participants. We will maintain an office or agency in the location specified in the prospectus supplement for the applicable securities, where notices and demands in respect of the securities and the indenture may be delivered to us and where certificated securities may be surrendered for payment, registration of transfer or exchange.

19

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any legal requirements in effect from time to time.

Redemption notices will be sent to DTC. If less than all of the securities of a particular series are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in the securities of such series to be redeemed.

Neither DTC nor Cede & Co. (or such other DTC nominee) will consent or vote with respect to the securities. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns the consenting or voting rights of Cede & Co. to those direct participants to whose accounts the securities of such series are credited on the record date, identified in a listing attached to the omnibus proxy.

So long as securities are in book-entry form, we will make payments on those securities to the depositary or its nominee, as the registered owner of such securities, by wire transfer of immediately available funds. If securities are issued in definitive certificated form under the limited circumstances described below, we will have the option of making payments by check mailed to the addresses of the persons entitled to payment or by wire transfer to bank accounts in the United States designated in writing to the applicable trustee or other designated party at least 15 days before the applicable payment date by the persons entitled to payment, unless a shorter period is satisfactory to the applicable trustee or other designated party.

Redemption proceeds, distributions and dividend payments on the securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us on the payment date in accordance with their respective holdings shown on DTC records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers in bearer form or registered in “street name.” Those payments will be the responsibility of participants and not of DTC or us, subject to any statutory or regulatory requirements in effect from time to time. Payment of redemption proceeds, distributions and dividend payments to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC, is our responsibility, disbursement of payments to direct participants is the responsibility of DTC, and disbursement of payments to the beneficial owners is the responsibility of direct and indirect participants.

Except under the limited circumstances described below, purchasers of securities will not be entitled to have securities registered in their names and will not receive physical delivery of securities. Accordingly, each beneficial owner must rely on the procedures of DTC and its participants to exercise any rights under the securities and the indenture.

The laws of some jurisdictions may require that some purchasers of securities take physical delivery of securities in definitive form. Those laws may impair the ability to transfer or pledge beneficial interests in securities.

DTC may discontinue providing its services as securities depositary with respect to the securities at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor depositary is not obtained, securities certificates are required to be printed and delivered.

As noted above, beneficial owners of a particular series of securities generally will not receive certificates representing their ownership interests in those securities. However, if:

•DTC notifies us that it is unwilling or unable to continue as a depositary for the global security or securities representing such series of securities or if DTC ceases to be a clearing agency registered under the Exchange Act at a time when it is required to be registered and a successor depositary is not appointed within 90 days of the notification to us or of our becoming aware of DTC’s ceasing to be so registered, as the case may be;

•we determine, in our sole discretion, not to have such securities represented by one or more global securities; or

•an Event of Default has occurred and is continuing with respect to such series of securities,

20

•we will prepare and deliver certificates for such securities in exchange for beneficial interests in the global securities. Any beneficial interest in a global security that is exchangeable under the circumstances described in the preceding sentence will be exchangeable for securities in definitive certificated form registered in the names that the depositary directs. It is expected that these directions will be based upon directions received by the depositary from its participants with respect to ownership of beneficial interests in the global securities.

We have obtained the information in this section and elsewhere in this prospectus concerning DTC and DTC’s book-entry system from sources that are believed to be reliable, but we take no responsibility for the accuracy of this information.

SELLING SECURITY HOLDERS

Information about selling security holders will be set forth in a prospectus supplement, in a post-effective amendment or in filings we will make with the SEC which are incorporated into this prospectus by reference.

22

PLAN OF DISTRIBUTION

We, or one or more selling security holders to be identified in a prospectus supplement, may sell the securities of or within any series to or through agents, underwriters, dealers, remarketing firms or other third parties or directly to one or more purchasers or through a combination of any of these methods. We may issue securities as a dividend or distribution. In some cases, we or dealers acting with us or on our behalf may also purchase securities and reoffer them to the public. We or one or more selling security holders may also offer and sell, or agree to deliver, securities pursuant to, or in connection with, any option agreement or other contractual arrangement.

Each time we offer and sell securities covered by this prospectus, we will provide a prospectus supplement or supplements that will describe the method of distribution and set forth the terms of the offering, including:

•the name or names of any underwriters, dealers or agents and the amounts of securities underwritten or purchased by each of them;

•the public offering price of the securities and the proceeds to us or the selling security holders, as the case may be;

•any over-allotment options under which underwriters may purchase additional securities from us;

•any underwriting discounts or commissions or agency fees and other items constituting underwriters’ or agents’ compensation;

•terms and conditions of the offering;

•any discounts, commissions or concessions allowed or reallowed or paid to dealers; and

•any securities exchange or market on which the securities may be listed.

Agents

We or one or more selling security holders may use agents to sell securities. We or one or more selling security holders will name any agent involved in offering or selling securities, and disclose any commissions that we or one or more selling security holders will pay to the agent, in the applicable prospectus supplement. Unless we tell you otherwise in the applicable prospectus supplement, the agents will agree to use their reasonable efforts to solicit purchases for the period of their appointment or to sell our securities on a continuing basis. Our agents may be deemed to be underwriters under the Securities Act of any of the securities that they offer or sell.

Underwriters

We or one or more selling security holders may sell securities to underwriters. If we or one or more selling security holders use underwriters, the underwriters will acquire the securities for their own account, including without limitation through underwriting, purchase, security lending, repurchase or other agreements with us or one or more selling security holders, as the case may be. Unless we or one or more selling security holders tell you otherwise in the applicable prospectus supplement, the underwriters may resell those securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Unless the applicable prospectus supplement states otherwise, the obligations of the underwriters to purchase any series of securities will be subject to conditions precedent, and the underwriters will be obligated to purchase all of the securities if any are purchased. The underwriters may change any initial public offering price and any discounts or concessions they give to dealers.

Dealers

We or one or more selling security holders may use a dealer to sell the securities. If we or one or more selling security holders use a dealer, we or one or more selling security holders, as the case may be, as principal, will sell the securities to the dealer who will then sell the securities to the public at varying prices that the dealer will determine at the time it sells our securities.

23

Direct Sales

We or one or more selling security holders may solicit directly offers to purchase the securities, and we or one or more selling security holders may sell securities directly to purchasers without the involvement of agents, underwriters or dealers. We will describe the terms of our direct sale in the applicable prospectus supplement.

Other Means of Distribution

Securities may also be offered and sold, if we so indicate in the applicable prospectus supplement, by one or more firms (“remarketing firms”) acting as principals for their own accounts or as our agents in connection with a remarketing of such securities following their purchase or redemption or otherwise. Remarketing firms may be deemed to be underwriters under the Securities Act in connection with the securities they remarket.

We may engage in at the market offerings into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act

We may authorize our agents, dealers and underwriters to solicit offers by certain institutions to purchase the securities at the public offering price under delayed delivery contracts. If we use delayed delivery contracts, we will disclose that we are using them in the applicable prospectus supplement and will tell you when we will demand payment and delivery of the securities under the delayed delivery contracts. These delayed delivery contracts will be subject only to the conditions that we describe in the prospectus supplement.

With or without the involvement of agents, underwriters, dealers, remarketing firms or other third parties, we may utilize the Internet or other electronic bidding or ordering systems for the pricing and allocation of securities. Such a system may allow bidders to directly participate, through electronic access to an auction site, by submitting conditional offers to buy that are subject to acceptance by us. The use of such a system may affect the price or other terms at which such securities are sold. The final offering price at which securities would be sold, and the allocation of securities among bidders, would be based in whole or in part on the results of the bidding process or auction. Many variations of the Internet auction or pricing and allocating systems are likely to be developed in the future, and we may utilize such systems in connection with the sale of securities. We will describe in the applicable prospectus supplement how any auction or bidding process will be conducted to determine the price or any other terms of the securities, how potential investors may participate in the process and, where applicable, the nature of the obligations of any agent, underwriter, dealer or remarketing firm with respect to the auction or ordering system.

Derivative Transactions and Hedging

We may enter into derivative or other hedging transactions involving the securities with third parties, or sell securities not covered by the prospectus to third parties in privately-negotiated transactions. If we so indicate in the applicable prospectus supplement, in connection with those derivative transactions, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions, or may lend securities in order to facilitate short sale transactions by others. 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 securities, and may use securities received from us in settlement of those derivative or hedging transactions to close out any related open borrowings of securities. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement (or a post-effective amendment to the registration statement of which this prospectus is a part).

We may effect sales of securities in connection with forward sale, option or other types of agreements with third parties. Any distribution of securities pursuant to any forward sale agreement may be effected from time to time in one or more transactions that may take place through a stock exchange, including block trades or ordinary broker’s transactions, or through broker-dealers acting either as principal or agent, or through privately-negotiated transactions, or through an underwritten public offering, or through a combination of any such methods of sale, at market prices prevailing at the time of sale, at prices relating to such prevailing market prices or at negotiated or fixed prices.

We may loan or pledge securities to third parties that in turn may sell the securities using this prospectus and the applicable prospectus supplement or, if we default in the case of a pledge, may offer and sell the securities from time to time using this prospectus and the applicable prospectus supplement. Such third parties may transfer their short positions to investors in our securities or in connection with a concurrent offering of other securities offered by this prospectus and the applicable prospectus supplement or otherwise.

24

General Information

Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Overallotment involves sales in excess of the offering size, which create a short position. This short sales position may involve either “covered” short sales or “naked” short sales. Covered short sales are short sales made in an amount not greater than the underwriters’ over-allotment option to purchase additional securities in an offering. The underwriters may close out any covered short position either by exercising their over-allotment option or by purchasing securities in the open market. To determine how they will close the covered short position, the underwriters will consider, among other things, the price of securities available for purchase in the open market, as compared to the price at which they may purchase securities through the over-allotment option. Naked short sales are short sales in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing securities in the open market. A naked short position is more likely to be created if the underwriters are concerned that, in the open market after pricing, there may be downward pressure on the price of the securities that could adversely affect investors who purchase securities in an offering. Stabilizing transactions permit bids to purchase the underlying security for the purpose of fixing the price of the security so long as the stabilizing bids do not exceed a specified maximum. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions.

Similar to other purchase transactions, an underwriter’s purchase to cover syndicate short sales or to stabilize the market price of the securities may have the effect of raising or maintaining the market price of the securities or preventing or mitigating a decline in the market price of the securities. As a result, the price of the securities may be higher than the price that might otherwise exist in the open market. The imposition of a penalty bid might also have an effect on the price of the securities if it discourages resales of the securities.

Unless the applicable prospectus supplement states otherwise, each series of securities will be a new issue of securities and will have no established trading market, other than our common stock. which is traded on the New York Stock Exchange and the Tel Aviv Stock Exchange as of the date of this prospectus. We may elect to list any other series of securities on any exchange or market, but we are not obligated to do so. Any underwriters to whom the securities are sold for a public offering may make a market in those securities. However, those underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of, or the trading market for, any of the securities.

Any underwriters, dealers, agents, remarketing firms and third parties may be customers of, engage in transactions with, or perform services for, Ormat in the ordinary course of their business. We will describe the nature of any such relationship in any prospectus supplement naming any such underwriter, dealer, agent, remarketing firm or third party.
