ABOUT THIS PROSPECTUS SUPPLEMENT

This document is in two parts. The first part is this prospectus supplement, which describes the terms of this offering and also adds to, and updates, information contained in the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The second part, the accompanying prospectus, dated December 13, 2013, including the documents incorporated by reference therein, provides more general information. Generally, when we refer to this prospectus, we are referring to both parts of this document combined. To the extent there is a conflict between the information contained in this prospectus supplement, on the one hand, and the information contained in the accompanying prospectus or in any document incorporated by reference that was filed with the Securities and Exchange Commission, or SEC, before the date of this prospectus supplement, on the other hand, you should rely on the information in this prospectus supplement. If any statement in one of these documents is inconsistent with a statement in another document having a later date — for example, a document incorporated by reference into the accompanying prospectus — the statement in the document having the later date modifies or supersedes the earlier statement. You should read this prospectus supplement, the accompanying prospectus, the documents incorporated by reference into this prospectus supplement and the accompanying prospectus, and any free writing prospectus that we have authorized for use in connection with this offering, in their entirety before making an investment decision.

You should rely on the information contained in or incorporated by reference into this prospectus supplement, the accompanying prospectus and in any free writing prospectus that we have authorized for use in connection with this offering. We have not, and the underwriter has not, authorized anyone to provide you with different information. We are not, and the underwriter is not, making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information contained in this prospectus supplement, the accompanying prospectus, the documents incorporated by reference into this prospectus supplement and the accompanying prospectus, and any free writing prospectus that we have authorized for use in connection with this offering, is accurate only as of the respective dates of those documents. Our business, financial condition, results of operations and prospects may have changed since those dates. You should also read and consider the information in the documents to which we refer you in the sections of this prospectus supplement entitled “Incorporation of Documents by Reference” and “Where You Can Find More Information.”

Unless we state otherwise or the context otherwise requires, references to “Rubicon,” “Company,” “us,” “we” or “our” in this prospectus supplement mean Rubicon Technology, Inc., and do not include the consolidated subsidiaries of Rubicon Technology, Inc. When we refer to “you” in this section, we mean all purchasers of the securities being offered by this prospectus supplement, whether they are the holders or only indirect owners of those securities.

RISK FACTORS

An investment in our common stock involves risks. Please consider carefully the risks described below together with the risk factors described in our Annual Report on Form 10-K for the year ended December 31, 2012 and our other periodic reports filed with the SEC, which are incorporated by reference in this prospectus supplement. Before making any investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus supplement or the accompanying prospectus. These risks could materially affect our business, results of operations or financial condition and affect the value of our common stock. You could lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business, results of operations or financial condition.

Risks Related to this Offering

We will have broad discretion over the use of the net proceeds to us from this offering and may apply the proceeds to uses that do not improve our operating results or the value of the common stock being offered hereby.

We will have broad discretion to use the net proceeds to us from this offering, and investors will be relying solely on the judgment of our board of directors and management regarding the application of the proceeds. See the section entitled “Use of Proceeds.” Although we expect to use the net proceeds from this offering to fund our research and development of new products, for expansion and to provide funds for general corporate purposes, we have not allocated these proceeds for specific purposes. Investors will not have the opportunity, as part of their investment decision, to assess whether the proceeds are being used appropriately. Our use of the proceeds may not improve our operating results or increase the value of the common stock being offered hereby.

If you purchase shares of our common stock in this offering, you will experience immediate and substantial dilution.

Purchasers of our common stock in this offering will pay a price per share that exceeds the net tangible book value per share of our common stock. After giving effect to the sale of 2,650,000 shares of our common stock in this offering at the public offering price of $10.65 per share, and after deducting the underwriting discount and estimated offering expenses payable by us, you will experience immediate dilution of $1.89 per share, representing the difference between our as adjusted net tangible book value per share as of September 30, 2013 after giving effect to this offering and the public offering price. See the section entitled “Dilution” below for a more detailed illustration of the dilution you will incur if you purchase common stock in this offering.

If we issue additional common stock, or securities convertible into or exchangeable or exercisable for common stock, our stockholders, including investors who purchase shares of our common stock in this offering, will experience additional dilution, and any such issuances may result in downward pressure on the price of our common stock. We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders.

We may continue to require additional capital following this offering to fund additional product research and development efforts and the introduction of new products. If we are unable to raise additional capital when needed, we may be forced to delay, reduce or eliminate our product research and development programs or delay the introduction of new products.

Developing advanced electronic materials and related products and introducing new products to the market can be expensive. We expect our research and development expenses to increase in connection with our ongoing product research and development plans. If we are required to conduct additional studies beyond those that we currently expect, our expenses could increase beyond what we currently anticipate and the timing of the release of any new products may be delayed. In addition, introducing newly developed products to the market

Table of Contents

often requires investment before revenue is generated from those products. Other than the proceeds from this offering, we currently have no commitments or arrangements for any additional financing to fund our product research and development programs other than through our loan facility. We believe our existing cash, cash equivalents and short-term investments and interest thereon, together with the net proceeds of this offering, will be sufficient to fund our projected operating requirements for at least the next 12 months. However, we may need to raise substantial additional capital in the future to complete the development and commercialization of our new products.

We may finance future cash needs for new product research and development or product introductions through public or private equity offerings, debt financings or corporate collaborations and licensing arrangements. Additional funds may not be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not available, we may be required to delay, reduce the scope of or eliminate one or more of our product research and development programs. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience additional dilution, and debt financing, if available, may involve restrictive covenants. To the extent that we raise additional funds through corporate collaborations and licensing arrangements, it may be necessary to relinquish some rights to our technologies or our new products or grant licenses on terms that may not be favorable to us. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time.

Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed elsewhere in this “Risk Factors” section, and under similar headings in the other documents that are incorporated by reference into this prospectus supplement and the accompanying prospectus. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect.

Our future funding requirements, both near and long-term, will depend on many factors, including, but not limited to:

 

•

the initiation, progress, timing, costs and results of studies and trials required for our new products;

 

•

the number and characteristics of new products that we pursue;

 

•

the terms and timing of any future collaboration, licensing or other arrangements that we may establish;

 

•

the cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;

 

•

the effect of competing technological and market developments;

 

•

the cost of establishing sales, marketing and distribution capabilities for any new products; and

 

•

the extent to which we acquire or invest in businesses, products or technologies.

FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus, the documents we have filed with the SEC that are incorporated herein and therein by reference and any free writing prospectus that we have authorized for use in connection with this offering may provide information, whether orally or in writing, which are deemed to be “forward-looking” within the meaning of the Private Securities Litigation Reform Act of 1995. These statements may be identified by the use of forward-looking terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “should” or the negative thereof or other variations thereon or comparable terminology. All statements contained or incorporated in this prospectus supplement which address operating performance, events or developments that we expect or anticipate may occur in the future, including statements related to our expectations, beliefs, plans, objectives, assumptions or future events or performance, are forward-looking statements. These forward-looking statements and other information are based on our beliefs as well as assumptions made by us using information currently available. Such forward-looking statements, because they relate to future events, are by their very nature subject to many important factors that could cause actual results to differ materially from those contemplated by the forward-looking statements contained in this prospectus supplement.

Information regarding important factors that could cause actual results to differ, perhaps materially, from those in the Company’s forward-looking statements is contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012, which is incorporated into this prospectus supplement by reference and, if applicable, any risk factors described in the accompanying prospectus. See “Where You Can Find More Information” below for information about how to obtain a copy of this annual report.

USE OF PROCEEDS

We estimate that the net proceeds from the sale of the 2,650,000 shares of common stock we are offering will be approximately $26.2 million, after deducting the underwriting discount and the estimated offering expenses payable by us. If the underwriter exercises in full its option to purchase additional shares, we estimate that the net proceeds to us will be approximately $30.2 million.

The Company intends to use the net proceeds from this offering to fund its research and development of new products, for expansion and to provide funds for general corporate purposes. We will have significant discretion in the use of the proceeds. General corporate purposes may include repayment of debt, investments in or extensions of credit to our subsidiaries, repurchases of common stock, capital expenditures and the financing of possible acquisitions or business expansions. The net proceeds from this offering may be invested temporarily in short-term, interest-bearing, investment- grades securities, certificates of deposit or government securities, or applied to repay short-term obligations until they are used for their stated purpose.

DIVIDEND POLICY

We have never declared or paid cash dividends on our common stock. We currently intend to retain future earnings to finance growth and development of our business, and we do not anticipate declaring or paying any cash dividends in the foreseeable future.

PRICE RANGE OF COMMON STOCK

Our common stock began trading on the Nasdaq Global Market under the symbol “RBCN” on November 16, 2007. As of September 30, 2013, our common stock was held by approximately 29 stockholders of record and there were 24,428,777 shares of our common stock outstanding. Because many shares of our common stock are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of beneficial stockholders represented by these record holders. The following table sets forth the high and low sales prices for our common stock as reported on the Nasdaq Global Market for the periods indicated.

 

		Price Range of Common Stock
		High				Low
2012
First Quarter		$	13.59			$	8.20
Second Quarter		$	10.92			$	8.46

DILUTION

Our net tangible book value as of September 30, 2013 was approximately $211.0 million, or $8.64 per share. Net tangible book value per share is determined by dividing our total tangible assets, less total liabilities, by the number of shares of our common stock outstanding as of September 30, 2013. Dilution with respect to net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of our common stock in this offering and the net tangible book value per share of our common stock immediately after this offering.

After giving effect to the sale of 2,650,000 shares of our common stock in this offering at the public offering price of $10.65 per share and after deducting the underwriting discount and estimated offering expenses payable by us, our as adjusted net tangible book value as of September 30, 2013 would have been approximately $237.1 million, or $8.76 per share. This represents an immediate increase in net tangible book value of $0.12 per share to existing stockholders and immediate dilution of $1.89 per share to investors purchasing our common stock in this offering at the public offering price. The following table illustrates this dilution on a per share basis:

 

Public offering price per share						$	10.65
Net tangible book value per share as of September 30, 2013		$	8.64
Increase in net tangible book value per share attributable to investors purchasing our common stock in this offering		$	0.12
As adjusted net tangible book value per share after this offering						$	8.76
Dilution per share to investors purchasing our common stock in this offering						$	1.89

If the underwriter exercises in full its option to purchase up to 397,500 additional shares of our common stock, the as adjusted net tangible book value after this offering would be $8.78 per share, representing an increase in net tangible book value of $0.14 per share to existing stockholders and immediate dilution of $1.87 per share to investors purchasing our common stock in this offering at the public offering price.

The above discussion and table is based on 24,428,777 shares outstanding as of September 30, 2013, and excludes as of that date:

 

•

options to purchase 1,924,381 shares of our common stock at a weighted average exercise price of $12.50 per share;

 

•

267,826 shares of our common stock issuable upon exercise of warrants outstanding at an exercise price of $3.65 per share; and

 

•

2,334,782 of our common stock available for future grants under our stock plans.

The above discussion also excludes options, restricted stock units, restricted stock and common stock issued after September 30, 2013 under our 2007 Stock Incentive Plan, including options to purchase 14,450 shares of our common stock at an exercise price of $12.11 per share, 45,941 restricted stock units, none of which are vested, 27,925 shares of restricted stock, none of which are vested, and 4,746 shares of our common stock. In addition, options to purchase 12,012 shares of our common stock were cancelled after September 30, 2013.

To the extent that options or warrants outstanding as of September 30, 2013 are exercised or other shares are issued, investors purchasing our common stock in this offering will experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe that we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of our common stock or securities convertible into or exchangeable or exercisable for our common stock, the issuance of these securities could result in further dilution to our stockholders, including investors purchasing our common stock in this offering. See “Risk Factors — If you purchase shares of our common stock in this offering, you will experience immediate and substantial dilution.”

UNDERWRITING

We intend to offer the shares of our common stock through an underwriter, Canaccord Genuity Inc. We have agreed to sell to the underwriter, and the underwriter has agreed to purchase from us, 2,650,000 shares of our common stock.

The underwriter has agreed to purchase all of the shares of our common stock (other than those covered by the over-allotment option described below) sold under the underwriting agreement. The underwriter is offering the shares of our common stock, when, as and if issued to and accepted by them, subject to approval of legal matters by its counsel, including the validity of the common stock and other conditions contained in the underwriting agreement, such as the receipt by the underwriter of officers’ certificates and legal opinions. The underwriter reserves the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

We have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act of 1933, as amended, and to contribute to payments that the underwriter may be required to make in respect of those liabilities.

Commissions and Discounts

In connection with the sale of the shares of our common stock offered hereby, the underwriter may be deemed to have received compensation in the form of underwriting discounts.

The expenses related to this offering payable by the Company are estimated to be approximately $400,000. We are responsible for these expenses and up to $100,000 of the expenses of the underwriter, including fees and expenses of the underwriter’s counsel, whether or not this offering is completed.

The following table shows the public offering price, underwriting discount and proceeds before expenses to us. The information assumes either no exercise or full exercise by the underwriter of its overallotment option.

 

		Per Share				Without Option				With Option
Public offering price		$	10.65			$	28,222,500			$	32,455,875
Underwriting discount		$	0.58			$	1,537,000			$	1,767,550
Proceeds, before expenses, to us		$	10.07			$	26,685,500			$	30,688,325

Over-Allotment Option

We have granted an option to the underwriter to purchase up to 397,500 additional shares of our common stock at $10.07 per share. The underwriter may exercise this option for 30 days from the date of this prospectus supplement solely to cover any over-allotments.

Lock-Up Agreements

We and our executive officers and directors have entered into lock-up agreements with the underwriter. Under these agreements, we and each of these persons may not, without the prior written approval of the underwriter, subject to limited exceptions, offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of, or announce the intention to otherwise dispose of, any shares of our common stock or any securities convertible into or exercisable or exchangeable for our common stock or enter into any swap, hedge or other agreement or arrangement that transfers, in whole or in part, the economic risk of ownership of any shares of our common stock or securities convertible into or exercisable or exchangeable for our common stock, or engage in any short selling of any shares of our common stock or securities convertible into or exercisable or exchangeable for our common stock. These restrictions will be in effect for a period of 90 days after the date of this prospectus supplement.

Table of Contents

Notwithstanding the termination of the lock-up period outlined above, and subject to certain exceptions, in the event that either (i) during the last 17 days of the lock-up period, we issue an earnings release or material news or a material event relating to us occurs, or (ii) prior to the expiration of the lock-up period, we announce that we will release earnings results during the 16-day period beginning on the last day of the lock-up period, then the expiration of the lock-up period will be extended until the expiration of the 18-day period beginning on the date of the issuance of an earnings release or the occurrence of the material news or material event, as applicable, unless the underwriter waives, in writing, such extension. At any time and without public notice, the underwriter and our board of directors, acting jointly, may in its sole discretion release all or some of the securities from these lock-up agreements.

Price Stabilization and Short Positions

Until distribution of the shares of our common stock is completed, SEC rules may limit the underwriter from bidding for and purchasing shares of our common stock. However, the underwriter may engage in transactions that stabilize the price of the shares of our common stock, such as bids or purchases to peg, fix or maintain that price.

If the underwriter creates a short position in our common stock in connection with this offering (i.e., if it sells more shares of our common stock than are listed on the cover page of this prospectus supplement), the underwriter may reduce that short position by purchasing shares of our common stock in the open market. The underwriter may also elect to reduce any short position by exercising all or part of the over-allotment option described above. Purchases of shares of our common stock to stabilize its price or to reduce a short position may cause the price of shares of our common stock to be higher than it might be in the absence of such purchases.

The underwriter also may impose a penalty bid, whereby the underwriter may reclaim selling concessions allowed to other broker-dealers in respect of the common stock sold in this offering for its account if the underwriter repurchases the shares in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the common stock, which may be higher than the price that might otherwise prevail in the open market. The imposition of a penalty bid may also affect the price of the shares of our common stock in that it discourages resales of those shares of our common stock.

The underwriter has advised us that these transactions may be effected on The NASDAQ Global Market or otherwise. Neither we nor the underwriter make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of shares of our common stock. In addition, neither we nor the underwriter make any representation that the underwriter will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Relationship with Rubicon

In the ordinary course of business, the underwriter and its affiliates may, in the future, engage in investment banking or other transactions of a financial nature with us, including the provision of certain advisory services to us or financing transactions for which they may receive customary compensation. The underwriter had previously been engaged by us to provide us with financial advisory services. Pursuant to our agreement with the underwriter, the underwriter had the right, but not the obligation, from November 29, 2012 to December 31, 2013, to review strategic and financial transactions of the Company, for which it would have received customary fees. In addition, for such transactions that occur prior to March 31, 2014, but in which the underwriter does not participate, the underwriter remains entitled to any such applicable fees. However, in connection with this offering, the underwriter will only be receiving the underwriting discount and the expense reimbursement described above.

MATERIAL U.S. FEDERAL TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

The following is a general discussion of the material U.S. federal income tax consequences of the ownership and disposition of our common stock by a non-U.S. holder (as defined below) who holds our common stock as a capital asset (generally, property held for investment). For purposes of this discussion, you are a “non-U.S. holder” if you are a beneficial owner of our common stock that is an individual, corporation (or other entity treated as a corporation for federal income tax purposes), estate or trust (other than a grantor trust) and you are not, for U.S. federal income tax purposes:

 

•

an individual who is a citizen or resident of the U.S.;

 

•

a corporation created or organized in or under the laws of the U.S., or of any state thereof or the District of Columbia; or

 

•

an estate whose income is subject to U.S. federal income taxation regardless of its source; or a trust, in general, if a U.S. court is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have authority to control all substantial decisions of the trust or if the trust has made a valid election to be treated as a U.S. person under applicable U.S. Treasury regulations.

If you are an individual, you may be treated as a resident of the U.S. in any calendar year for U.S. federal income tax purposes by, among other ways, being present in the U.S. for at least 31 days in that calendar year and for an aggregate of at least 183 days during a three-year period ending in the current calendar year (and where certain other conditions are satisfied and certain applicable exceptions do not apply, including exceptions applicable under certain tax treaties). For purposes of this calculation, you would count all of the days present in the current year, one-third of the days present in the immediately preceding year and one-sixth of the days present in the second preceding year.

This discussion does not consider:

 

•

U.S. state, U.S. local, U.S. estate, or non-U.S. tax consequences;

 

•

all aspects of U.S. federal income taxes or specific facts and circumstances that may be relevant to a particular non-U.S. holder’s tax position;

 

•

the tax consequences for the stockholders, partners or beneficiaries of a non-U.S. holder;

 

•

special tax rules that may apply to particular holders, such as financial institutions, insurance companies, tax-exempt organizations, controlled foreign corporations, passive foreign investment companies, government instrumentalities, holders owning more than 5% of our common stock, U.S. expatriates, former citizens or residents of the U.S., partnerships or other flow-through entities, part-year non-resident aliens, broker-dealers and traders in securities, persons who elect to mark-to-market their securities; or

 

•

special tax rules that may apply to a non-U.S. holder that holds our common stock as part of a “straddle,” “hedge,” “conversion transaction,” “synthetic security” or other integrated investment.

If a partnership, including any entity or arrangement treated as a partnership for U.S. federal income tax purposes, is a holder of our common stock, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership that may acquire our common stock, or a partner in such a partnership, you should consult a tax advisor regarding the tax consequences to you of the partnership’s acquisition, ownership and disposition of our common stock.

The following discussion is based on provisions of the U.S. Internal Revenue Code of 1986, as amended, existing and proposed Treasury regulations and administrative and judicial interpretations, all as of the date of this prospectus supplement, and all of which are subject to change, retroactively or prospectively. The following summary assumes that you hold our common stock as a capital asset (generally, property held for investment). We undertake no obligation to publicly update or otherwise revise this summary whether as a result of new Treasury regulations, Code sections, judicial and administrative interpretations or otherwise. The

Table of Contents

Code, Treasury Regulations and judicial and administrative interpretations thereof are also subject to various interpretations, and there can be no guarantee that the Internal Revenue Service, or the IRS, or U.S. courts will agree with the tax consequences described in this summary.

Each non-U.S. holder should consult a tax advisor regarding the U.S. federal, state, local and non-U.S. income, tax treaty and other tax consequences of holding and disposing of shares of our common stock.

Dividends

We do not anticipate making cash distributions on our common stock in the foreseeable future. In the event, however, that we make distributions on our common stock, those payments will constitute dividends for U.S. federal tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed our current and accumulated earnings and profits, they first will constitute a return of capital and will reduce a non-U.S. holder’s basis in our common stock, but not below zero, and then will be treated as gain from the sale of stock. Any dividend paid to a non-U.S. holder on our common stock that is not effectively connected with the non-U.S. holder’s conduct of a U.S. trade or business will generally be subject to U.S. federal withholding tax at a rate of 30%, or a lower rate under an applicable income tax treaty.

You should consult your tax advisor regarding your entitlement to benefits under a relevant income tax treaty. Generally, in order for us to withhold tax at a lower treaty rate, you must (a) timely provide the payor with a properly executed applicable IRS Form W-8 (or other applicable successor form) and any applicable attachments certifying that (i) you are not a United States person and (ii) you are eligible for the lower treaty rate or (b) if our common stock is held through certain foreign intermediaries, timely satisfy the relevant certification requirements of applicable U.S. Treasury regulations. The applicable certifications must be provided to the applicable withholding agent prior to the payment of dividends and may be required to be updated periodically.

If you are eligible for a reduced rate of U.S. federal withholding tax under an income tax treaty, you may obtain a refund or credit of any excess amounts withheld by filing an appropriate claim for a refund on a timely basis with the IRS.

If the dividend is effectively connected with your conduct of a trade or business in the U.S. and, if an income tax treaty applies, is attributable to a permanent establishment maintained by you in the U.S., the dividend will generally be exempt from U.S. federal withholding tax, provided that you supply us with a properly executed IRS Form W-8ECI. In this case, the dividend will be taxed on a net income basis at the regular graduated rates and in the manner applicable to U.S. persons and, if you are a foreign corporation, you may be subject to an additional branch profits tax at a rate of 30% or a lower rate as may be specified by an applicable income tax treaty.

Sales, Exchanges, or Other Taxable Dispositions of Common Stock

Subject to the discussions below regarding backup withholding and “FATCA” (as defined below), you generally will not be subject to U.S. federal income tax on gain recognized on a disposition of our common stock unless:

 

•

the gain is effectively connected with your conduct of a trade or business in the U.S. and, if an income tax treaty applies, is attributable to a permanent establishment maintained by you in the U.S., in which case the gain will be taxed on a net income basis at the regular graduated rates and in the manner applicable to U.S. persons and, if you are a foreign corporation, you may be subject to an additional branch profits tax at a rate of 30% or a lower rate as may be specified by an applicable income tax treaty;

Table of Contents

•

you are an individual who holds our common stock as a capital asset, are present in the U.S. for 183 days or more in the taxable year of the disposition and meet other requirements, in which case the gain derived from the sale will be subject to a flat 30% tax, which may be offset by U.S. source capital losses; or

 

•

we are or have been a “United States real property holding corporation,” or USRPHC, for U.S. federal income tax purposes at any time during the shorter of the five-year period ending on the date of disposition and the period that you held our common stock and certain other conditions are met, in which case the gain will be taxed on a net income basis in the manner described in the first bullet paragraph above.

Generally, a corporation is a USRPHC if the fair market value of its “United States real property interests” equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus its other assets used or held for use in a trade or business. The tax relating to stock in a USRPHC generally will not apply to a non-U.S. holder whose holdings, direct and indirect, at all times during the applicable period, constituted 5% or less of our common stock, provided that our common stock was regularly traded (within the meaning of section 897(c)(3) of the Code) on an established securities market in the calendar year of disposition. We believe that we are not currently, and we do not anticipate becoming in the future, a USRPHC for U.S. federal income tax purposes.

Information Reporting and Backup Withholding

We must report annually to the IRS and to each non-U.S. holder the amount of dividends paid to such holder and the tax withheld with respect to such dividends, regardless of whether withholding was required. Copies of the information returns reporting such dividends and withholding may also be made available to the tax authorities in other countries under the provisions of an applicable income tax treaty.

Payments of dividends in respect of, or proceeds on the disposition of, our common stock made to a Non-U.S. Holder may be subject to additional information reporting and backup withholding unless such Non-U.S. Holder establishes an exemption, for example, by properly certifying that such Non-U.S. Holder is not a United States person as defined under the Code on a valid IRS Form W-8BEN or another appropriate version of IRS Form W-8 and including any applicable attachments (provided that the payor does not have actual knowledge or reason to know that such Non-U.S. Holder is a United States person).

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from payments made to a Non-U.S. Holder will reduce the Non-U.S. Holder’s U.S. federal income tax liability. If withholding results in an overpayment of taxes, a refund or credit may generally be obtained from the IRS, provided the required information is timely furnished to the IRS. A Non-U.S. Holder should consult its tax advisor regarding the application of the information reporting and backup withholding rules.

Additional Withholding Requirements

Under legislation enacted in 2010, U.S. Treasury regulations and official IRS administrative guidance (commonly known as “FATCA”), a 30% United States federal withholding tax may apply to any dividends paid after June 30, 2014, and to the gross proceeds from a disposition of our common stock occurring after December 31, 2016, in each case paid to (i) a “foreign financial institution” (as specifically defined in the legislation), whether such foreign financial institution is the beneficial owner or an intermediary, unless such foreign financial institution agrees to verify, report and disclose its United States “account” holders (as specifically defined in the legislation) and meets certain other specified requirements or (ii) a non-financial foreign entity, whether such non-financial foreign entity is the beneficial owner or an intermediary, unless such entity provides a certification that the beneficial owner of the payment does not have any substantial United States owners or provides the name, address and taxpayer identification number of each such “substantial United States owner” ( as defined under the Code and applicable Treasury regulations) and certain other specified requirements are met. In certain cases, the relevant foreign financial institution or non-financial

Table of Contents

foreign entity may qualify for an exemption from, or be deemed to be in compliance with, these rules. Persons located in a jurisdiction that has entered into an intergovernmental agreement with the U.S. governing FATCA (an IGA) may be subject to different rules. Application of this FATCA tax does not depend on whether the payment otherwise would be exempt from U.S. federal withholding tax under the other exemptions described above. Prospective holders should consult their own tax advisors regarding this new legislation, any applicable IGA and whether this legislation or IGA may be relevant to your ownership and disposition of our common stock.

ABOUT RUBICON TECHNOLOGY, INC.

OUR BUSINESS

We are an advanced electronic materials provider that develops, manufactures and sells monocrystalline sapphire and other innovative crystalline products for light-emitting diodes (“LEDs”), radio frequency integrated circuits (“RFICs”), blue laser diodes, optoelectronics and other optical applications. The emergence of sapphire in commercial volumes at competitive prices has enabled the development of new technologies such as high brightness (“HB”) white, blue and green LEDs and highly-integrated RFICs. We apply our proprietary crystal growth technology to produce high-quality sapphire products efficiently to supply our end-markets, and we work closely with our customers to meet their quality and delivery needs. We believe we are the leading supplier of sapphire products to the LED industry.

We are a vertically integrated manufacturer of high-quality sapphire substrates and optical windows that are used in a variety of high-growth, high-volume end market applications. During 2011 and 2012, our largest sales of product were six-inch polished sapphire wafers (substrates) for use in LED applications and in Silicon-on-Sapphire (“SoS”) RFICs. Two through four-inch diameter sapphire cores were our second largest product sales category during 2011 and 2012, and comprised the majority of our sales prior to 2011. Cores are sold to sapphire polishers who make wafers for use in LEDs and blue laser diodes. We also sell sapphire products used for windows and lenses in military, aerospace, sensor and other applications. We have extended our technology, giving us the ability to produce cores and wafers of up to twelve inches in diameter to support next generation LED and RFIC production.

We believe that LED production is following a similar path to that of production of integrated circuits on silicon substrates, which gradually migrated to production on increasingly larger substrates in order to reduce manufacturing costs. We feel that this migration to larger substrates and the related efficiency gains will help reduce the prices of LED devices and thereby facilitate greater adoption of LED technology in the backlighting and general lighting markets.

Our fully integrated in-house capabilities enable us to maintain our high-quality standards while controlling costs. We design, assemble and maintain our own proprietary crystal growth furnaces to grow high-purity, low-stress, ultra-low-defect-density sapphire crystals. In addition, we possess state-of-the-art capabilities in high-precision core drilling, wafer slicing, surface lapping, edge bevel grinding and wafer cleaning processes. We have recently extended our vertical integration by introducing a patented sapphire substrate for the LED market. We foster a strong sense of innovation and agility in our product development teams in an attempt to develop new products more effectively and to rapidly capture market growth.

We plan to leverage our technological advantage in efficiently producing high-quality, large-diameter sapphire products to maintain our leadership position and capitalize on future growth opportunities. To attain this goal, we are investing in research and development activities, continuing to enhance our operational capabilities, increasing our brand recognition and diversifying into new market segments.

We are a Delaware corporation incorporated on February 7, 2001. Our common stock is listed on the NASDAQ Global Market under the symbol “RBCN.” Our principal executive offices are located at 900 East Green Street, Bensenville, Illinois 60106. The telephone number at our principal executive offices is (847) 295-7000. Our website address is www.rubicontechnology.com. Information contained on our website is not incorporated by reference into this prospectus, and you should not consider information contained on our website to form any part of this prospectus.

Our consolidated ratio of earnings to fixed charges for each of the five most recently completed fiscal years and any required interim periods will be specified in a prospectus supplement or in a document that we file with the SEC and incorporate by reference pertaining to the issuance, if any, by us of debt securities in the future.

RISK FACTORS

Investing in our securities involves risk. Please carefully consider the risk factors described in our periodic reports filed with the SEC, which are incorporated by reference in this prospectus, as well as any prospectus supplement relating to a specific security. Before making any investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus or in any applicable prospectus supplement. These risks could materially affect our business, results of operation or financial condition and affect the value of our securities. You could lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business, results of operation or financial condition.

SUBSIDIARY GUARANTOR

If Rubicon Worldwide LLC, our wholly-owned subsidiary, becomes a guarantor from time to time in accordance with the applicable indenture (which we refer to as the “subsidiary guarantor” in this prospectus), it would fully and unconditionally guarantee our payment obligations under any series of debt securities offered by this prospectus. Financial information concerning our subsidiary guarantor and any non-guarantor subsidiaries will be included in our consolidated financial statements filed as part of our current and periodic reports pursuant to the Exchange Act to the extent required by the rules and regulations of the SEC. Additional information concerning our subsidiaries and us is included in our periodic reports and other documents incorporated by reference in this prospectus. Please read “Where You Can Find More Information.”

USE OF PROCEEDS

Unless otherwise indicated in any prospectus supplement, we intend to use the net proceeds from the sale of securities from a primary offering by us for working capital and other general corporate purposes. We will have significant discretion in the use of any net proceeds. General corporate purposes may include repayment of debt, investments in or extensions of credit to our subsidiaries, repurchases of common stock, capital expenditures and the financing of possible acquisitions or business expansions. The net proceeds from the sale of securities from a primary offering by us may be invested temporarily or applied to repay short-term obligations until they are used for their stated purpose.

The following description of our capital stock is intended as a summary only and is qualified in its entirety by reference to our amended and restated certificate of incorporation and amended and restated bylaws, which are filed as exhibits to the registration statement of which this prospectus is a part. We refer in this section to our amended and restated certificate of incorporation as our certificate of incorporation, and we refer to our amended and restated bylaws as our bylaws.

As of November 13, 2013, we had 24,433,523 shares of our common stock outstanding, of which 1,774,844 shares were held as treasury shares, options to purchase 286,006 shares of our common stock under our 2001 Equity Plan, all of which were exercisable, options to purchase 1,648,385 shares of our common stock under our 2007 Stock Incentive Plan, 1,212,219 of which were exercisable, restricted stock units of 45,941 under our 2007 Stock Incentive Plan, none of which were vested, and warrants to purchase 267,826 shares of our common stock, all of which were exercisable.

COMMON STOCK

As of November 13, 2013, there were 24,433,523 shares of our common stock outstanding, of which 1,774,844 shares were held as treasury shares. As of November 13, 2013, there were 29 holders of our common stock.

Holders of our common stock are entitled to one vote for each share of common stock held of record for the election of directors and on all matters submitted to a vote of stockholders. Holders of our common stock are entitled to receive dividends ratably, if any, as may be declared by our board of directors from time to time, subject to any preferential dividend rights of any preferred stock then outstanding. Upon our liquidation, dissolution, distribution of assets or winding up, holders of our common stock are entitled to share ratably in our remaining assets legally available after the payment of all our debts and other liabilities, subject to the preferential rights of any preferred stock then outstanding. Holders of our common stock have no preemptive, subscription, redemption or conversion rights. The rights, preferences and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future. Except as described below in “—Anti-takeover effects of Delaware law and provisions of our certificate of incorporation and bylaws,” a majority vote of our common stockholders is generally required to take action under our certificate of incorporation and bylaws.

All outstanding shares of our common stock are fully paid and nonassessable.

PREFERRED STOCK

Our board of directors is authorized, without action by the stockholders, to designate and issue up to 5.0 million shares of preferred stock in one or more series.

The issuance of preferred stock with voting or conversion rights may adversely affect the voting power or other rights of the

holders of our common stock. The issuance of preferred stock, while providing flexibility in connection with possible future financings and acquisitions and other corporate purposes, could, under certain circumstances, have the effect of delaying, deferring or preventing a change in control and could harm the market price of our common stock.

Our board of directors will make any determination to issue such shares based on its judgment as to our best interests and the best interests of our stockholders. We have no current plans to issue any shares of preferred stock.

OPTIONS

As of November 13, 2013, we had outstanding options to purchase 286,006 shares of common stock under our 2001 Equity Plan, all of which were exercisable. These options have an average exercise price of $7.70. As of November 13, 2013, we had outstanding options to purchase 1,648,385 shares of common stock under our 2007 Stock Incentive Plan, 1,212,219 of which were exercisable. These options have an average exercise price of $13.33.

RESTRICTED STOCK UNITS

As of November 13, 2013 we had outstanding restricted stock units of 45,941 under our 2007 Stock Incentive Plan, none of which were vested. Each restricted stock unit represents the right to receive one share of common stock upon satisfaction of vesting conditions.

Type of warrant		Number of shares of common stock issuable upon exercise of warrant				Exercise price per share of common stock				Expiration

Common Stock			24,380			$	3.65				1/27/2016

ANTI-TAKEOVER EFFECTS OF DELAWARE LAW AND PROVISIONS OF OUR CERTIFICATE OF INCORPORATION AND BYLAWS

Certificate of incorporation and bylaw provisions

Our certificate of incorporation and bylaws include a number of provisions that may have the effect of delaying, deferring or preventing another party from acquiring control of us and encouraging persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with our board of directors rather than pursue non-negotiated takeover attempts. These provisions include the items described below.

Board composition and filling vacancies. Our board is divided into three classes serving staggered three-year terms, with one class being elected each year. Directors may be removed only for cause and then only by the affirmative vote of the holders of 75% or more of the shares then entitled to vote at an election of directors. Furthermore, any vacancy on our board of directors, however occurring, including a vacancy resulting from an increase in the size of our board, may only be filled by the affirmative vote of a majority of our directors then in office even if less than a quorum. The classification of our board of directors and the limitations on the removal of directors and filling of vacancies could make it more difficult for a third party to acquire, or discourage a third party from seeking to acquire, control of our company.

No written consent of stockholders. All stockholder actions must be taken by a vote of the stockholders at an annual or special meeting, and stockholders may not take any action by written consent in lieu of a meeting. This limit may lengthen the amount of time required to take stockholder actions and would prevent the amendment of our bylaws or removal of directors by our stockholders without holding a meeting of stockholders.

Table of Contents

Meetings of stockholders. Only a majority of the members of our board of directors then in office may call special meetings of stockholders and only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders. Our bylaws limit the business that may be conducted at an annual meeting of stockholders to those matters properly brought before the meeting.

Advance notice requirements. Our bylaws establish advance notice procedures with regard to stockholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of our stockholders. These provisions may have the effect of precluding the conduct of certain business at a meeting if proper procedures are not followed.

Amendment to certificate of incorporation and bylaws. As required by the Delaware General Corporation Law, any amendment of our certificate of incorporation must first be approved by a majority of our board of directors, and if required by law or our certificate of incorporation, must thereafter be approved by a majority of the outstanding shares entitled to vote on the amendment and a majority of the outstanding shares of each class entitled to vote thereon as a class, except that the amendment of the provisions relating to stockholder action, board composition and the filling of vacancies, limitation of liability and the amendment of our certificate of incorporation must be approved by not less than 75% of the outstanding shares entitled to vote on the amendment, and not less than 75% of the outstanding shares of each class entitled to vote thereon as a class. Our bylaws may be amended by the affirmative vote of a majority of the directors then in office, subject to any limitations set forth in the bylaws, and may also be amended by the affirmative vote of at least 75% of the outstanding shares entitled to vote on the amendment, or, if our board of directors recommends that the stockholders approve the amendment, by the affirmative vote of the majority of the outstanding shares entitled to vote on the amendment, in each case voting together as a single class.

Undesignated preferred stock. Our certificate of incorporation provides for 5.0 million authorized shares of preferred stock. The existence of authorized but unissued shares of preferred stock may enable our board of directors to impede an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise. Our certificate of incorporation grants our board of directors broad power to establish the rights and preferences of authorized and unissued shares of preferred stock. The issuance of shares of preferred stock could decrease the amount of earnings and assets available for distribution to holders of shares of our common stock. The issuance may also adversely affect the rights and powers, including voting rights, of these holders and may have the effect of delaying, deterring or preventing a change in control of us.

Delaware law

We are subject to Section 203 of the Delaware General Corporation Law, an anti-takeover provision. In general, the provision prohibits a publicly-held Delaware corporation from engaging in a business combination with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder. A “business combination” includes a merger, sale of 10% or more of our assets and certain other transactions resulting in a financial benefit to the stockholder. For purposes of Section 203, an “interested stockholder” is defined to include any person that is:

 

•

the owner of 15% or more of the outstanding voting stock of the corporation;

 

•

an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation, at any time within three years immediately prior to the relevant date; or

 

•

an affiliate or associate of any person described above.

However, the above provisions of Section 203 do not apply if:

 

•

our board of directors approves the transaction that made the stockholder an interested stockholder before the date of that transaction; or

 

6

Table of Contents

•

after the completion of the transaction that resulted in the stockholder becoming an interested stockholder, that stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, excluding shares owned by our officers and directors; or

 

•

on or subsequent to the date of the transaction, the business combination is approved by our board of directors and authorized at a meeting of our stockholders by an affirmative vote of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.

Stockholders may, by adopting an amendment to the corporation’s certificate of incorporation or bylaws, elect for the corporation not to be governed by Section 203, effective 12 months after adoption. Neither our certificate of incorporation nor our bylaws exempt us from the restrictions imposed under Section 203. It is anticipated that the provisions of Section 203 may encourage companies interested in acquiring us to negotiate in advance with our board of directors.

NASDAQ GLOBAL MARKET LISTING

Our common stock is listed on the NASDAQ Global Market under the trading symbol “RBCN.”

TRANSFER AGENT AND REGISTRAR

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company.

LIMITATION OF LIABILITY OF DIRECTORS

Our certificate of incorporation contains a provision that limits the liability of our directors for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted by the Delaware General Corporation Law. Such limitation does not, however, affect the liability of a director (1) for any breach of the director’s duty of loyalty to us or our stockholders, (2) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (3) in respect of certain unlawful dividend payments or stock redemptions or purchases and (4) for any transaction from which the director derives an improper personal benefit. The effect of this provision is to eliminate our rights and the rights of our stockholders (through stockholders’ derivative suits) to recover monetary damages against a director for breach of the fiduciary duty of care as a director (including breaches resulting from negligent or grossly negligent behavior) except in the situations described in clauses (1) through (4) above. This provision does not limit or eliminate our rights or the rights of our stockholders to seek non-monetary relief such as an injunction or rescission in the event of a breach of a director’s duty of care. In addition, our directors and officers have indemnification protection.

SELLING STOCKHOLDERS

This prospectus relates to the possible resale by certain affiliates of Rubicon, who we refer to as the “Selling Stockholders” in this prospectus, of up to $40,000,000 of shares of our common stock. These shares were acquired from Rubicon by the Selling Stockholders in a series of private transactions prior to our initial public offering. Information about the potential Selling Stockholders who offer securities under the registration statement of which this prospectus is a part will be set forth in prospectus supplements, post-effective amendments and/or filings we make with the SEC under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are incorporated by reference.

PLAN OF DISTRIBUTION

Rubicon may sell common stock, preferred stock, debt securities, guarantees of debt securities or warrants and the Selling Stockholders may sell common stock in one or more of the following ways from time to time:

 

•

to or through underwriters or dealers;

 

•

by itself or themselves directly;

 

•

through agents;

 

•

through a combination of any of these methods of sale; or

 

•

through any other methods described in a prospectus supplement.

The prospectus supplements relating to an offering of securities will set forth the terms of such offering, including:

 

•

the name or names of any underwriters, dealers or agents;

 

•

the purchase price of the offered securities and the proceeds to Rubicon and to the Selling Stockholders from the sale;

 

•

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

 

•

any initial public offering price, any discounts or concessions allowed or reallowed or paid to dealers and any securities exchanges on which such offered securities may be listed.

Any initial public offering prices, discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

The distribution of securities may be effected, from time to time, in one or more transactions, including block transactions and transactions on the NASDAQ Global Market or any other organized market where the

 

12

---

Table of Contents

securities may be traded. The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration may be cash or another form negotiated by the parties. Agents, underwriters or broker-dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from us or from the purchasers of the securities. Dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and compensation received by them on resale of the securities may be deemed to be underwriting discounts. If such dealers or agents were deemed to be underwriters, they may be subject to statutory liabilities under the Securities Act.

If underwriters are used in the sale, the underwriters will acquire the offered securities for their own account and may resell them from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The offered securities may be offered either to the public through underwriting syndicates represented by one or more managing underwriters or by one or more underwriters without a syndicate. Unless otherwise set forth in a prospectus supplement, the obligations of the underwriters to purchase any series of securities will be subject to certain conditions precedent and the underwriters will be obligated to purchase all of such series of securities if any are purchased.

In connection with underwritten offerings of the offered securities and in accordance with applicable law and industry practice, underwriters may over-allot or effect transactions that stabilize, maintain or otherwise affect the market price of the offered securities at levels above those that might otherwise prevail in the open market, including by entering stabilizing bids, effecting syndicate covering transactions or imposing penalty bids, each of which is described below.

 

•

A stabilizing bid means the placing of any bid, or the effecting of any purchase, for the purpose of pegging, fixing or maintaining the price of a security.

 

•

A syndicate covering transaction means the placing of any bid on behalf of the underwriting syndicate or the effecting of any purchase to reduce a short position created in connection with the offering.

 

•

A penalty bid means an arrangement that permits the managing underwriter to reclaim a selling concession from a syndicate member in connection with the offering when offered securities originally sold by the syndicate member are purchased in syndicate covering transactions.

These transactions may be effected on the NASDAQ Global Market, in the over-the-counter market, or otherwise. Underwriters are not required to engage in any of these activities, or to continue such activities if commenced.

If a dealer is used in the sale, Rubicon and the Selling Stockholders, if any, will sell such offered securities to the dealer, as principal. The dealer may then resell the offered securities to the public at varying prices to be determined by that dealer at the time for resale. The names of the dealers and the terms of the transaction will be set forth in the prospectus supplement relating to that transaction.

Offered securities may be sold directly by Rubicon and the Selling Stockholders, if any, to one or more institutional purchasers, or through agents designated by Rubicon or the Selling Stockholders from time to time, at a fixed price or prices, which may be changed, or at varying prices determined at the time of sale. Any agent involved in the offer or sale of the offered securities in respect of which this prospectus is delivered will be named, and any commissions payable by Rubicon and the Selling Stockholders, if any, to such agent will be set forth in the prospectus supplement relating to that offering, unless otherwise indicated in such prospectus supplement. Any such agent will be acting on a best efforts basis for the period of its appointment.

Underwriters, dealers and agents may be entitled under agreements entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments that the underwriters, dealers or agents may be required to make in respect thereof. If required, the

 

13

---

Table of Contents

prospectus supplement will describe the terms and conditions of such indemnification or contribution. Underwriters, dealers and agents may be customers of, engage in transactions with, or perform services for us and our affiliates in the ordinary course of business.

Under the securities laws of some states, the securities offered by this prospectus may be sold in those states only through registered or licensed brokers or dealers.

Any person participating in the distribution of common stock registered under the registration statement that includes this prospectus will be subject to applicable provisions of the Exchange Act, and the applicable SEC rules and regulations, including, among others, Regulation M, which may limit the timing of purchases and sales of any shares of our common stock by any such person. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of our common stock to engage in market-making activities with respect to our common stock. These restrictions may affect the marketability of our common stock and the ability of any person or entity to engage in market-making activities with respect to our common stock.

Other than our common stock, which is listed on the NASDAQ Global Market, each of the securities issued hereunder will be a new issue of securities, will have no prior trading market, and may or may not be listed on a national securities exchange. Any common stock sold pursuant to a prospectus supplement will be listed on the NASDAQ Global Market, subject to official notice of issuance. Any underwriters to whom Rubicon sells securities for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot assure you that there will be a market for the offered securities.

Fees and Commissions

In compliance with the guidelines of the Financial Industry Regulatory Authority (“FINRA”), the aggregate maximum discount, commission or agency fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of any offering pursuant to this prospectus and any applicable prospectus supplement or pricing supplement, as the case may be; however, it is anticipated that the maximum commission or discount to be received in any particular offering of securities will be significantly less than this amount.

If more than 10% of the net proceeds of any offering of securities made under this prospectus will be received by FINRA members participating in the offering or affiliates or associated persons of such FINRA members, the offering will be conducted in accordance with FINRA Conduct Rule 5110(h).

LEGAL MATTERS

The validity of the securities offered hereby will be passed upon for us by Winston & Strawn LLP. Certain legal matters may be passed upon for any agents or underwriters by counsel for such agents or underwriters identified in the applicable prospectus supplement.

EXPERTS

The audited financial statements and management’s assessment of the effectiveness of internal control over financial reporting incorporated by reference in this prospectus and elsewhere in the registration statement have been so incorporated by reference in reliance upon the reports of Grant Thornton LLP, independent registered public accountants, upon the authority of said firm as experts in accounting and auditing in giving said reports.
