EXPLANATORY NOTE

Rubicon Technology, Inc. (the Company, Rubicon, we, us, or our) is filing this
Amendment No. 1 on Form 10-K/A (the Amendment No. 1) to amend our Annual Report on Form 10-K for the year ended December 31, 2015, originally filed with the Securities and Exchange Commission (the SEC) on
March 14, 2016 (the Original Form 10-K), to include the information required by Items 10 through 14 of Part III of Form 10-K. This information was previously omitted from the Original Form 10-K in reliance on General Instruction
G(3) to Form 10-K, which permits the information in the above-referenced items to be incorporated into the Form 10-K by reference to our definitive proxy statement if such proxy statement is filed no later than 120 days after our fiscal year end. We
are filing this Amendment No. 1 to provide the information required in Part III of Form 10-K because a definitive proxy statement containing such information will not be filed by the Company within 120 days after the end of the fiscal year
covered by the Form 10-K. The reference on the cover of the Original Form 10-K to the incorporation by reference of portions of our definitive proxy statement into Part III of the Original Form10-K is hereby deleted.

Pursuant to the rules of the SEC, Part IV Item 15 has also been amended to contain the currently dated certifications from the
Companys Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer) pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. The certifications of the Companys Chief Executive
Officer and Chief Financial Officer are attached to this Amendment No. 1 as Exhibits 31.3 and 31.4. Because no financial statements have been included in this Amendment No. 1 and this Amendment No. 1 does not contain or amend any
disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted.

Except as
described above and set forth herein, this Amendment No. 1 does not amend any other information set forth in the Original Form 10-K, and we have not updated disclosures included therein to reflect any subsequent events. This Amendment
No. 1 should be read in conjunction with the Original Form 10-K and with our filings with the SEC subsequent to the Original Form 10-K.

The value of the annual and
committee fees payable to our directors remains unchanged in 2016 but each of the directors received such fees in the form of restricted stock awards rather than receiving a portion of such fees in cash. The restricted stock awards vest in four
equal installments at the end of each calendar quarter in 2016. The Board of Directors determined that their 2016 fees would be paid solely in the form of equity in order to preserve cash and in light of the Companys objective to become cash
flow positive, which further aligns their interests with those of the Companys stockholders.

COMPENSATION DISCUSSION AND ANALYSIS

The following discussion and analysis of compensation arrangements of our named executive officers for 2015 should be read together with the
compensation tables and related disclosures set forth below.

Executive Summary

Our compensation programs are intended to align our named executive officers interests with those of our stockholders by rewarding
performance that meets or exceeds the goals the Compensation Committee establishes with the objective of increasing stockholder value. Consistent with our pay for performance philosophy, the total compensation received by our named executive
officers will vary based on individual and corporate performance measured against annual and long-term performance goals. Our named executive officers total compensation is comprised of a mix of base salary, annual incentive compensation and
long-term incentive awards.

Below is a comparison of 2015 and 2014 revenue and earnings, which are key metrics on which the Compensation
Committee measures management performance. Please see Managements Discussion and Analysis of Financial Conditions and Results of Operations in our Original Form 10-K for a more detailed description of our fiscal year 2015
financial results.

|Diluted loss per share |  | $                          | (2.98 | ) |                            | $ | (1.70 | )

Our financial performance is a key factor in the compensation decisions and outcomes for the fiscal year. In
2015 and 2014, executive officers were awarded no bonuses as threshold performance levels were not achieved.

We believe that the
compensation of our executive officers should facilitate the achievement of short-term corporate goals as well as the performance of long-term business objectives. It is the responsibility of the Compensation Committee of our Board of Directors to
administer our compensation practices to ensure that they are competitive and include incentives which are designed to appropriately drive corporate performance. Our Compensation Committee reviews and approves all of our compensation policies,
including executive officer salaries, bonuses and equity incentive compensation.

We endeavor to maintain a high level of corporate
governance over our executive pay programs. The following policies were in effect during 2014 and remained in effect in 2015:



| |  |  | No significant perquisites offered: Our executives participate in broad-based Company-sponsored programs on the same basis as other full-time employees.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Separation of governance positions: In line with corporate governance best practices, we have separated the roles of Chairman of the Board of Directors and Chief Executive Officer.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | No SERPs: Our executives participate in the same retirement plan generally available to other full-time employees, and we do not offer supplemental executive retirement programs to our executives.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Executive ownership guidelines: We have implemented stock ownership guidelines for our executive officers, which are more fully described in Elements of Our Executive Compensation ProgramsStock
ownership guidelines below.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | No excise tax gross-ups: We do not provide change in control excise tax gross-ups in any of our executive employment agreements or compensation plans.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Independence of executive compensation consultant: The compensation consultant used by the Compensation Committee in 2015 did not provide any services to management and had no prior relationship with our named
executive officers. The Compensation Committee also assessed the independence of the consultant pursuant to the applicable rules of the SEC and the NASDAQ Stock Market and concluded that the consultant did not raise any conflicts of interest for the
2015 year.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Objectives of Our Executive Compensation Programs

Our compensation programs for our named executive officers are designed to achieve the following objectives:



| |  |  | attract and retain talented and experienced executives in our industry;
| | - |  | -----------------------------------------------------------------------



| |  |  | motivate and reward executives whose knowledge, skills and performance are critical to our success;
| | - |  | ---------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | align the interests of our executives and stockholders, by encouraging executives to increase long-term stockholder value and rewarding executives when stockholder value increases; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | motivate our executives to manage our business to meet our short-term and long-term corporate goals and business objectives, and reward them for meeting these objectives.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We use a mix of short-term compensation in the form of base salaries and cash incentive bonuses and long-term compensation in the form of
equity incentive compensation to provide a total compensation structure that is designed to encourage our executives to achieve these objectives.

Determining Executive Compensation

The
Compensation Committee is responsible for developing, administering and interpreting the compensation program for executive officers and other key employees. Our Compensation Committee was appointed by our Board of Directors and consists entirely of
directors who are outside directors for purposes of Section 162(m) of the Internal Revenue Code of 1986, as amended (the Code), and non-employee directors for purposes of Rule 16b-3 under the Exchange Act.

The Compensation Committee may delegate some or all of its responsibilities to one or more subcommittees whenever necessary to comply
with any statutory or regulatory requirements or otherwise deemed appropriate by the committee. The Compensation Committee has the authority to retain consultants and other advisors to assist with its duties and has sole authority to approve the
fees and other retention terms of such consultants and advisors.

Historically, our Chief Executive Officer has made recommendations to
the Compensation Committee regarding the salaries, bonus arrangements and equity grants, if any, for all key employees other than himself. For executive officers whose bonus awards are based partly on individual performance, the Chief Executive
Officers evaluation of such performance is provided to and reviewed by the Compensation Committee. Based on the foregoing, the Compensation Committee uses its judgment in making compensation decisions that will best carry out our philosophy
and objectives for executive compensation. The Compensation Committee also reviews the performance of the Chief Executive Officer and sets his compensation consistent with our philosophy. The Chief Executive Officer does not participate in, and is
not present for, deliberations or decisions concerning his compensation.

Within the context of the overall objectives of our compensation
programs, we determined the specific amounts of compensation to be paid to each of our executives in 2015 based on a number of factors, including, but not limited to:



| |  |  | the roles and responsibilities of our executives;
| | - |  | -------------------------------------------------



| |  |  | the individual experience and skills of our executives;
| | - |  | -------------------------------------------------------



| |  |  | the amounts of compensation being paid to our other executives;
| | - |  | ---------------------------------------------------------------



| |  |  | the performance of the Company against targets pre-established by the Board of Directors;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | our executives historical compensation at our Company; and
| | - |  | -----------------------------------------------------------



| |  |  | our understanding of the amount of compensation generally paid by similarly situated companies to their executives with similar roles and responsibilities.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------

In evaluating the compensation generally paid by similarly situated companies, our Compensation Committee has obtained guidance on appropriate
executive compensation practices from executive search firms in the course of recruiting executives for Rubicon. In addition, we have historically taken into account available data relating to the compensation practices of other companies within and
outside our industry. In December 2014, the Compensation Committee engaged the consulting firm of Meridian Compensation Partners, LLC (Meridian) to assist us in analyzing our compensation structure and making suggestions for our compensation
structure for 2015. Meridian provided advice to the Compensation Committee regarding proposed 2015 compensation levels and severance benefits for Mr. Weissman and Ms. Graffy based on their new positions. Although the Compensation Committee
uses the information from Meridian and industry group surveys, the Compensation Committee makes all final decisions regarding the appropriate compensation for our executives. The peer group used for purposes of developing and assessing these
executives compensation levels for 2015 consisted of the following six companies: Advanced Analogic Tech; Bolt Technology Corp; Cascade Microtech Inc.; Lighting Sciences Group; MIPS Technologies Inc.; and Supertex Inc.

Stockholder Say on Pay

At our 2014
Annual Meeting of Stockholders, our stockholders approved, on an advisory basis, our executive compensation program with approximately 98% support. Taking into account the favorable outcome of our stockholder advisory approval vote at the 2014
Annual Meeting of Stockholders, we did not make specific changes to our executive compensation program in 2015. We will continue to take into account the result of future stockholder advisory votes when reviewing and monitoring our compensation
program and structure.

At our 2011 Annual Meeting of Stockholders, our stockholders approved a three-year frequency of stockholder
advisory voting to approve our executive compensation with approximately 54% support. In accordance with the voting results, we provide our stockholders with an opportunity to cast an advisory vote on executive compensation every three years.

Elements of Our Executive Compensation Programs

Our executive compensation primarily consists of base salary, cash incentive and discretionary bonuses, equity-based incentives and benefit
programs. We believe it is important that the interests of our executives are aligned with those of our long-term stockholders; therefore, equity incentive compensation constitutes a significant portion of our total executive compensation.

We discuss each of the primary elements of our executive compensation in detail below. While we have identified particular compensation
objectives that each element of executive compensation serves, our compensation programs are designed to complement each other and collectively serve all of our executive compensation objectives described above.

Annual cash compensation

Base
salary

Base salaries are intended to provide a level of compensation sufficient to attract and retain an effective management team
when considered in combination with the performance-based and other components of our compensation program. The base salary of each executive officer is reviewed annually to determine if it is equitably aligned with our other executive officers and
is at a sufficient level to attract and retain top talent. Salaries are adjusted to reflect individual roles and performance and may be increased at other times if a change in the scope of the officers responsibilities justifies such
consideration or in order to maintain salary equity among executive officers. We believe that a competitive base salary is a necessary element of any compensation program designed to attract and retain talented and experienced executives. We also
believe that attractive base salaries can serve as an effective reward for the executives overall performance.

Pursuant to the
terms of their employment agreements, the annual base salaries for 2015 for Mr. Weissman, Ms. Graffy and Mr. Tamim were $300,000, $200,000 and $225,000, respectively. We formally evaluate executive performance on an annual basis, and
these evaluations are one of the factors considered in making adjustments to base salaries. In connection with their promotions to new positions in December 2014, (i) Mr. Weissmans base salary increased from $233,950 to $300,000, and
(ii) Ms. Graffys base salary increased from $158,970 to $200,000. After consideration of the Companys performance within our industry, the base salaries for our named executive officers were not increased in 2015.

Cash incentive bonuses

The primary objectives of our incentive bonus plan are to provide an incentive for superior work, to motivate our executives toward even higher
achievement and business results, to tie our executives goals and interests to ours and our stockholders and to enable us to attract and retain highly qualified individuals. These targets are typically set in the first three months of
the year. The targets under our incentive bonus plan are mutually agreed upon by the independent directors and each of the executives. For 2015, Mr. Weissman was entitled to receive a bonus of up to one-half of his base salary and
Ms. Graffy and Mr. Tamim were entitled to receive a bonus of up to 30% of their base salaries, in each case based on our achieving the following pre-determined targets. Fifty percent (50%) of the bonus would be paid if the
Companys operations had been cash flow positive (the Cash Flow Target), meaning that the Company was cash flow positive for the fourth quarter of 2015 and was reasonably expected to be cash flow positive in 2016. If, and only if
the Cash Flow Target had been achieved, then the remaining 50% of the target bonus could have been achieved based upon the following performance goals: an additional 25% of the target bonus would be paid if the Companys patterned sapphire
wafer (PSS) infrastructure was running at full capacity, 15% of the target bonus would be paid if the Company had generated revenue from sales of Sapphire on Glass (SoG) and had satisfactorily completed the proof of concept
work on its near-net shape pure sapphire products, and 10% of the target bonus would be paid if the run rate of annualized revenue from the Companys optical business for 2015, based on revenue recognized in the fourth quarter of 2015, was at
least 50% greater than the revenue recognized in 2014, and such run rate was reasonably expected to continue at such level or greater for 2016. The 2015 Cash Flow Target was not achieved and, therefore, no incentive cash bonuses were paid to
executive officers for fiscal 2015.

The Compensation Committee believed the targets described above were the most appropriate criteria to
determine the value of our executives efforts and considering current and projected market conditions. After evaluating which key milestones were likely to provide the Company with a significantly enhanced market position, the Cash Flow Target
was chosen as the applicable threshold performance measure to govern payment of the cash incentive bonuses and the vesting of the restricted stock units (discussed below).

Signing bonus

In connection with
Mr. Weissmans appointment as Interim Chief Executive Officer and President in September 2014, the Board of Directors approved a $100,000 cash bonus payable to Mr. Weissman, with $50,000 payable on the date of the Companys next
regular payroll and the remaining $50,000 payable on the earlier of (i) the six (6) month anniversary of Mr. Weissmans appointment or (ii) such time as the Company hires a new Chief Executive Officer. The second half of the
signing bonus was paid in March 2015.

Equity incentive compensation

In 2008, our Board of Directors adopted a policy generally to grant equity awards to executives once per year to the extent equity awards are
to be granted during such year (except in the case of newly hired executives, as described below). With respect to newly hired executives, our practice is typically to make equity grants at the first meeting of the Board of Directors following such
executives hire date. We do not have any program, plan or practice to time equity awards in coordination with the release of material non-public information.

On February 18, 2015, the Company entered into employment agreements with Mr. Weissman and Ms. Graffy. Pursuant to the terms of
their employment agreements, Mr. Weissman was granted restricted stock units valued at $100,000 and Ms. Graffy was granted restricted stock units valued at $50,000. The vesting condition metrics of the restricted stock units were
determined by the Compensation Committee. Fifty percent (50%) of the restricted stock units would have vested if the Companys operations had satisfied the Cash Flow Target (described above within the Cash Incentive Bonus). If, and only if
the Cash Flow Target had been achieved, then the remaining 50% of the restricted stock units would have been eligible to vest as follows: 25% of the restricted stock units would have vested if the Companys PSS infrastructure was running at
full capacity, 15% of the restricted stock units would have vested if the Company had generated revenue from sales of SoG and had satisfactorily completed the proof of concept work on its near-net shape pure sapphire products, and 10% of the
restricted stock units would have vested if the run rate of annualized revenue from the Companys optical business for 2015, based on revenue recognized in the fourth quarter of 2015, was at least 50% greater than the revenue recognized in
2014, and such run rate was reasonably expected to continue at such level or greater for 2016. The 2015 Cash Flow Target was not achieved and, as a result, the restricted stock unit awards were forfeited by Mr. Weissman and Ms. Graffy.

In addition, pursuant to the terms of their employment agreements, options to purchase shares of Company common stock were granted to
Mr. Weissman and Ms. Graffy on December 1, 2015. For Mr. Weissman, the number of options granted reflected the number of whole options nearest the target value of $250,000 determined using the fair market value per share as of
the date of grant. On December 1, 2015, Mr. Weissmans employment agreement was amended to reduce the value of the option grant to ensure that the number of shares subject to the option grant was within the annual grant limitations as
set forth in the Rubicon Technology, Inc. 2007 Stock Incentive Plan, as amended and restated effective March 23, 2011 (the 2007 Plan). For Ms. Graffy, the number of options granted reflected the number of whole options nearest
the target value of $100,000 determined using the fair market value per share as determined as of date of grant. Each option grant had a ten-year term, an exercise price equal to the closing price of the Companys common stock on the date prior
to the date of grant and provided for vesting in four equal annual installments.

On October 31, 2015, the Company entered into a
letter of appointment with Mr. Tamim. Upon the execution of the letter of appointment, the Companys Board of Directors granted to Mr. Tamim options to purchase 30,000 shares of the Company common stock under the 2007 Plan. The
options were granted with a ten-year term, with an exercise price equal to the closing price of the Companys common stock on the date prior to the date of grant and vest in four equal annual installments. On November 1, 2015, the Company
granted Mr. Tamim 50,000 restricted stock units under the 2007 Plan. The restricted stock units vest ratably over a three-year period and vest immediately upon a change in control.

The 2015 stock option and restricted stock unit grants were made pursuant to our 2007 Plan, which was adopted by our Board of Directors and
our stockholders in connection with our initial public offering. The 2007 Plan permits the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards and bonus shares. The 2007 Plan replaced our
2001 Equity Plan effective upon the consummation of our initial public offering.

Stock ownership guidelines

On September 18, 2012, the Compensation Committee approved stock ownership guidelines for executive officers of the Company. Under the
stock ownership guidelines, the executive officers are expected to hold common stock with a value equal to a designated multiple of annual base salary. The Chief Executive Officer target share ownership level is a value equal to three times his
annual base salary and the Chief Financial Officer and other executive officers target share ownership level is one times their annual base salary. The executive officers are to comply within five years from the date the guidelines become applicable
to them. Shares that count toward satisfaction of the stock ownership guidelines include:



| |  |  | shares owned outright;
| | - |  | ----------------------



| |  |  | in-the-money value of vested stock options;
| | - |  | -------------------------------------------



| |  |  | unvested restricted stock;
| | - |  | --------------------------



| |  |  | restricted stock units; and
| | - |  | ---------------------------



| |  |  | vested shares in 401(k) plan.
| | - |  | -----------------------------

##### Table of Contents

As of December 31, 2015, due to the significant drop in the Companys share price (and
in Mr. Tamims case, the fact that he was only recently hired), none of our named executive officers met the targeted stock ownership guidelines. Per the guidelines, Mr. Weissman has until September 2017, Ms. Graffy has until
December 2019 and Mr. Tamim has until October 2020 to come into compliance with the guidelines.

Benefits

All of our executive officers are eligible for benefits offered to employees generally, including life, health, disability and dental insurance
and our 401(k) plan. Consistent with our compensation philosophy, we intend to continue to maintain our current benefits for our executive officers. The Compensation Committee, in its discretion, may revise the executive officers benefits if
it deems it advisable.

Severance and change in control arrangements

In February 2015, we entered into employment agreements with Mr. Weissman and Ms. Graffy outlining the terms and conditions of their
employment in their new positions with the Company. We also entered into a letter of agreement with Mr. Tamim upon his appointment in October 2015 outlining the terms and conditions of his employment.

These employment agreements provide various benefits triggered by such employment-related actions as termination without cause, resignation
with good reason and/or termination without cause following a change in control. Such benefits may include salary continuation, bonuses, lump sum severance and/or the acceleration of equity award vesting. See Potential Payments Upon
Termination of Employment below for a description of the severance and change in control arrangements for our named executive officers.

In addition, each of our equity incentive plans provides for a potential acceleration of vesting of outstanding awards in the event that we
undergo a change in control, as defined in such plans. The 2007 Plan provides that in the event of change in control, each outstanding award will be treated as the Compensation Committee determines, including that the successor corporation or its
parent or subsidiary may be required to assume or substitute an equivalent award for each outstanding award. The Compensation Committee is not required to treat all awards similarly. If there is no assumption or substitution of outstanding awards,
the award recipient will fully vest in and have the right to exercise all of his or her outstanding options and stock appreciation rights, all restrictions on restricted stock and restricted stock units will lapse and all performance goals or other
vesting requirements for performance awards will be deemed achieved at 100% of target levels and all other terms and conditions will be deemed met. If an option or stock appreciation right is not assumed or substituted, the Compensation Committee
will provide notice to the award recipient that the option or stock appreciation right will be fully vested and exercisable for a period of time determined by the Compensation Committee in its discretion, and the option or stock appreciation right
will terminate upon the expiration of such period. Under the 2007 Plan, a change in control is deemed to occur when (i) a person becomes the beneficial owner (directly or indirectly) of at least 50% of the voting power represented by the
Companys outstanding voting securities, (ii) the Company sells or disposes of all or substantially all of its assets, (iii) the composition of the Board of Directors changes within a two-year period resulting in fewer than a majority of the
directors being incumbent directors (as defined in the 2007 Plan), or (iv) a merger or consolidation of the Company is consummated with any other corporation resulting in the voting securities of the Company outstanding immediately prior
thereto representing (either by remaining outstanding or by being converted into voting securities of the surviving entity or its parent) less than 50% of the total voting power represented by the voting securities of the Company or such
surviving entity or its parent outstanding immediately after such merger or consolidation.

In setting the terms of and determining
whether to approve these severance and change in control arrangements, our Compensation Committee or Board of Directors, as applicable, recognized that executives often face challenges securing new employment following a termination of their
existing employment and that distractions created by uncertain job security may have a detrimental impact on their performance. None of the foregoing benefits is triggered by a change in control unless the named executive officers employment
is terminated without cause following such change in control or the award is not assumed, or an equivalent right substituted, by the successor corporation. We believe the acceleration of option vesting under such circumstances is appropriate to
preserve the benefit intended to be provided to the executive while avoiding the acceleration of benefits where the executive is enjoying a continuation of the same or comparable benefit following the change in control. The levels of severance
benefits were set based on our Board of Directors collective experience and insight regarding severance benefits offered to executives at comparable companies.

Effect of accounting and tax treatment on compensation decisions

In the review and establishment of our compensation programs, we consider the anticipated accounting and tax implications to us and our
executives. In this regard, we began utilizing restricted stock and/or restricted stock units as additional forms of equity compensation incentives in fiscal 2015 in response to changes in the accounting treatment of equity awards under FASB ASC
Topic 718 Stock Compensation. While we consider the applicable accounting and tax treatment, these factors alone are not dispositive, and we also consider the cash and non-cash impact of the programs and whether a program is consistent with our
overall compensation philosophy and objectives.

Section 162(m) of the Code imposes a limit on the amount of compensation that we may
deduct in any one year with respect to our Chief Executive Officer and each of our next three most highly compensated executive officers other than our Chief Financial Officer, unless certain specific and detailed criteria are satisfied.
Performance-based compensation, as defined in the Code, is fully deductible if the programs are approved by stockholders and meet other requirements. We will continue to assess the impact of Section 162(m) on our compensation practices and
determine whether to qualify equity and cash awards as performance-based compensation.

COMPENSATION COMMITTEE REPORT

As detailed in its charter, the Compensation Committee of the Board of Directors oversees Rubicons executive compensation program on
behalf of the Board of Directors. In the performance of this function, the Compensation Committee, among other things, reviewed and discussed with management the Compensation Discussion and Analysis included in this report and in Rubicons
definitive proxy statement for its 2016 annual meeting of stockholders. Based upon the review and discussions referred to above, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be
included in Rubicons Annual Report on Form 10-K for the fiscal year ended December 31, 2015, as amended, and its definitive proxy statement for the 2016 annual meeting of stockholders.

COMPENSATION RISKS

We believe that risks arising from our compensation policies and practices for our employees are not reasonably likely to have a material
adverse effect on the Company. In addition, the Compensation Committee believes that the mix and design of the elements of executive compensation do not encourage management to assume excessive risks.

The Compensation Committee reviewed the elements of executive compensation to determine whether any portion of executive compensation
encouraged excessive risk taking and concluded:

|(1) | On March 17, 2015, the Company granted Mr. Weissman a $50,000 cash bonus in consideration of his service as the interim Chief Executive Officer. This reflects 50% of the signing bonus described above within
the Compensation Discussion and Analysis.

|(2) | On September 17, 2014, the Company granted Mr. Weissman a $50,000 cash bonus upon his appointment as interim Chief Executive Officer. This reflects the remaining 50% of the signing bonus described above within
the Compensation Discussion and Analysis.

|(3) | Amounts represent the full grant date fair value of the stock option awards, restricted stock awards and restricted stock units granted in 2015, 2014 and 2013, calculated in accordance with FASB ASC Topic 718. For a
discussion of the assumptions and methodologies used in calculating the grant date fair value of the stock option awards and restricted stock unit awards in 2015, please see Note 7 to the Companys consolidated financial statements in the
Original Form 10-K. The restricted stock units granted to Mr. Weissman and Ms. Graffy in 2015 were forfeited in March 2016 because the Cash Flow Target performance goal was not achieved; accordingly, the value in the table appears to
overstate the compensation to Mr. Weissman and Ms. Graffy in 2015.

|(1) | Amounts shown in the threshold column represent the amounts that would have been payable under our incentive bonus plan if just the Cash Flow Target was met. Under the terms of the awards, no cash
incentive bonus could be earned unless the Cash Flow Target was met. Amounts shown in the maximum column represent the amounts that would have been payable under such plan if all of the targets had been met. Because the Cash
Flow Target was not met, no cash incentive bonuses were paid to executives for fiscal 2015.

|(2) | Amounts shown in the threshold column represent the potential number of restricted stock units that would have vested if just the Cash Flow Target was met. Under the terms of the awards, none of the
restricted stock units would vest unless the Cash Flow Target was met. Amounts shown in the maximum column represent the potential number of restricted stock units that would have vested if all of the targets had been
met. Because the Cash Flow Target was not met, none of the restricted stock units vested in fiscal 2015.

|(3) | Exercise price of option awards are based on the closing price on NASDAQ of the Companys common stock on the day before the grant date.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------

|(4) | Values for restricted stock unit awards are based on the closing price of a share of our common stock on the day before the grant date. Values for stock option awards are based on the grant date value calculated in
accordance with FASB ASC Topic 718. For a discussion of the assumptions and methodologies used in calculating the grant date fair value of the restricted stock and stock option awards, please see Note 7 to the Companys consolidated financial
statements in the Original Form 10-K.

POTENTIAL PAYMENTS UPON TERMINATION OF EMPLOYMENT OR CHANGE IN CONTROL

Mr. Weissmans Severance Terms. Pursuant to the terms of his employment agreement, if Mr. Weissmans
employment is terminated by us without cause or if he resigns for good reason, he will receive a continuation of his annual base salary for twelve months thereafter and all of his outstanding stock option awards will become
vested, provided that Mr. Weissman delivers a release of claims to the Company. In addition, he will receive a continuation of his medical and welfare benefits for a period of twelve months thereafter. As of December 31, 2015,
Mr. Weissman would also have been eligible to vest in the performance-based restricted stock units granted to him in 2015 in the event that he was terminated without cause or for good reason, but those awards were forfeited in March 2016 and
could no longer be accelerated in connection with a termination of employment. If within two years after a change in control, as defined in the 2007 Plan and summarized within the Compensation Discussion and Analysis section
above, we terminate Mr. Weissman without cause or he resigns for good reason, he will be entitled to a lump sum payment equal to twelve months of his annual base salary in lieu of the salary continuation described above.

For purposes of Mr. Weissmans agreement (i) cause generally is defined as willful misconduct materially and
adversely affecting us; theft, fraud, embezzlement or similar behavior; indictment or conviction of a felony; or willfully failing to substantially perform the material duties of his position, other than failure resulting from incapacity due to
physical or mental illness, following a demand for performance delivered by the Board of Directors and a specified cure period of not less than 10 days; and (ii) good reason generally is defined as a material reduction in base
salary or benefits; substantial diminution in Mr. Weissmans duties, responsibilities or title, if uncured by us within 30 days of receipt of notice from Mr. Weissman; or relocation for a period of greater than six consecutive months
greater than 100 miles from the Chicago metropolitan area.



Ms. Graffys Severance Terms. Pursuant to the terms of her employment agreement, if Ms. Graffys employment is
terminated by us without cause or if she resigns for good reason, she will receive a continuation of her annual base salary for six months thereafter and all of her outstanding stock option awards will become vested, provided
that Ms. Graffy delivers a release of claims to the Company. In addition, she will receive a continuation of her medical and welfare benefits for a period of six months thereafter. As of December 31, 2015, Ms. Graffy would also have
been eligible to vest in the performance-based restricted stock units granted to her in 2015 in the event that she was terminated without cause or for good reason, but those awards were forfeited in March 2016 and could no longer be accelerated in
connection with a termination of employment. If within two years after a change in control, as defined in the 2007 Plan and summarized within the Compensation Discussion and Analysis section above, we terminate
Ms. Graffy without cause or she resigns for good reason, she will be entitled to a lump sum payment equal to fifty percent of her annual base salary in lieu of the salary continuation described above.

For purposes of Ms. Graffys agreement (i) cause generally is defined
as willful misconduct materially and adversely affecting us; theft, fraud, embezzlement or similar behavior; indictment or conviction of a felony; or willfully failing to substantially perform the material duties of her position, other than failure
resulting from incapacity due to physical or mental illness, following a demand for performance delivered by the Board of Directors and a specified cure period of not less than 10 days; and (ii) good reason generally is defined as a
material reduction in base salary or benefits; substantial diminution in Ms. Graffys duties, responsibilities or title, if uncured by us within 30 days of receipt of notice from Ms. Graffy; or relocation for a period of greater than
six consecutive months greater than 100 miles from the Chicago metropolitan area.

Mr. Tamims Severance
Terms. Pursuant to the terms of his letter agreement, if Mr. Tamims employment is terminated by us without cause or if he resigns for good reason, he will receive a continuation of his annual base salary
for six months thereafter and certain of his options and restricted stock units will become vested, provided that Mr. Tamim delivers a release of claims to the Company. In addition, he will receive a continuation of his medical and welfare
benefits for a period of six months thereafter. If within two years after a change in control, we terminate Mr. Tamim without cause or he resigns for good reason, he will be entitled to a lump sum payment equal to fifty percent of his annual
base salary in lieu of the salary continuation described above.

For purposes of Mr. Tamims agreement
(i) cause generally is defined as willful misconduct materially and adversely affecting us; theft, fraud, embezzlement or similar behavior; indictment or conviction of any criminal offence; or willfully failing to substantially
perform the material duties of his position, other than failure resulting from incapacity due to physical or mental illness, following a demand for performance delivered by the Board of Directors and a specified cure period of not less than 10 days;
(ii) good reason generally is defined as any reduction in base salary; substantial diminution in Mr. Tamims duties, responsibilities or title, if uncured by us within 30 days of receipt of notice from Mr. Tamim; or
relocation for a period of greater than six consecutive months greater than 100 miles from the Penang metropolitan area; and (iii) change in control generally is defined as the occurrence of (a) any consolidation or merger of the
Company pursuant to which the Companys stockholders immediately before the transaction do not retain immediately after the transaction, in substantially the same proportions as their ownership of shares of the Companys voting stock
immediately before the transaction, direct or indirect beneficial ownership of more than 50% of the total combined voting power of the outstanding voting securities of the surviving business entity, (b) any sale, lease, exchange or other
transfer (in one transaction or a series of related transactions) of all, or substantially all, of the Companys assets, or (c) the direct or indirect sale or exchange in a single or series of related transactions by the Companys
stockholders of more than 50% of the Companys voting stock.

Restrictive Covenants. Each executives employment
agreement contains customary non-competition and non-solicitation covenants. These restrictions survive for a period of 12 months after the executives resignation or termination, and in the event of a breach of his or her employment agreement,
the period is automatically extended by the period of the breach.

Equity Compensation Awards. The equity compensation awards
granted under the 2007 Plan may become vested upon a change in control. The 2007 Plan provides that in the event of change in control, as defined in the 2007 Plan, each outstanding award will be treated as the Compensation Committee
determines, including that the successor corporation or its parent or subsidiary may be required to assume or substitute an equivalent award for each outstanding award. The Compensation Committee is not required to treat all awards similarly. If
there is no assumption or substitution of outstanding awards, the award recipient will fully vest in and have the right to exercise all of his or her outstanding options and stock appreciation rights, all restrictions on restricted stock and
restricted stock units will lapse and all performance goals or other vesting requirements for performance awards will be deemed achieved at 100% of target levels and all other terms and conditions will be deemed met. If an option or stock
appreciation right is not assumed or substituted, the Compensation Committee will provide notice to the award recipient that the option or stock appreciation right will be fully vested and exercisable for a period of time determined by the
Compensation Committee in its discretion, and the option or stock appreciation right will terminate upon the expiration of such period. Notwithstanding the Compensation Committees general discretionary authority described above, the individual
award agreements may provide for the vesting of such awards upon the occurrence of a change in control.

LIMITATION
ON LIABILITY AND INDEMNITY

Our amended and restated certificate of incorporation contains provisions that limit or eliminate the
liability of our directors for monetary damages to the fullest extent permitted by Delaware law. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as a
director, except liability for:



| |  |  | any breach of the directors duty of loyalty to us or our stockholders;
| | - |  | -----------------------------------------------------------------------



| |  |  | any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions as provided in Section 174 of the Delaware General Corporation Law; or
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | any transaction from which the director derived an improper personal benefit.
| | - |  | -----------------------------------------------------------------------------

Our bylaws
provide that we are required to indemnify our directors and officers, in each case to the fullest extent permitted by Delaware law. Our bylaws also provide that we are obligated to advance expenses incurred by a director or officer in advance of the
final disposition of any action or proceeding and permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in that capacity regardless of whether we would otherwise
be permitted to indemnify him or her under the provisions of Delaware law. We have entered into agreements and intend to continue to enter into agreements to indemnify our executive officers and directors. With certain exceptions, these agreements
provide for indemnification for related expenses including, among other things, attorneys fees, judgments, fines and settlement amounts incurred by any of these individuals in any action or proceeding for which indemnification is available. We
believe these bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. We also maintain directors and officers insurance.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND
MANAGEMENT

Unless otherwise noted, the following table sets forth, as of April 26, 2016, the beneficial ownership of our common
stock by:



| |  |  | each person that is a beneficial owner of 5% of more of our outstanding shares of common stock;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | each of our named executive officers;
| | - |  | -------------------------------------



| |  |  | each of our directors; and
| | - |  | --------------------------



| |  |  | all of our executive officers and directors as a group.
| | - |  | -------------------------------------------------------

Beneficial ownership is determined in
accordance with the rules of the SEC. Except as described below, in computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares of common stock subject to options or warrants held by that person
that are currently exercisable or exercisable within 60 days of April 26, 2016 are deemed outstanding, but are not deemed outstanding for computing the percentage ownership of any other person. These rules generally attribute beneficial
ownership of securities to persons who possess sole or shared voting power or investment power with respect to such securities. Except as otherwise indicated, all of the shares reflected in the table are shares of common stock and all persons listed
below have sole voting and investment power with respect to the shares beneficially owned by them, subject to applicable community property laws. Percentage of beneficial ownership is based on 26,722,958 shares of common stock outstanding as of
April 26, 2016. Unless otherwise indicated in the footnotes below, the address for each beneficial owner is c/o Rubicon Technology, Inc., 900 East Green Street, Bensenville, Illinois 60106.

|ITEM 13. | CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE
|-------- | -------------------------------------------------------------------------

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

We recognize that transactions between Rubicon and related persons present a potential for actual or perceived conflicts of interest. Our
general policies with respect to such transactions are included in our Code of Ethics which is administered by our Audit Committee. All employees and members of our Board of Directors agree to be bound by the Code of Ethics. As a supplement to the
Code of Ethics, the Audit Committee adopted a written policy setting out the procedures and standards to be followed for the identification and evaluation of related party transactions. For purposes of the policy, a related party
transaction is any transaction or series of related transactions in excess of $120,000 in which we are a party and in which a related person has a material interest. Related persons include our directors, director nominees, executive
officers, beneficial owners of 5% or more of any class of our voting securities and members of their immediate families. The Audit Committee has determined that certain transactions are deemed to be pre-approved under this policy. These include
(i) transactions with another company in which the related persons only interest is as a director or beneficial owner of less than 10% of the equity interests in that other company and (ii) certain compensation arrangements that have
either been disclosed in our public filings with the SEC or approved by our Compensation Committee.

We collect information about
potential related party transactions in our annual questionnaires completed by directors, executive officers and certain beneficial owners of 5% or more of any class of our voting securities. Potential related party transactions are first reviewed
and assessed by our Secretary to consider the materiality of the transactions and then reported to the Audit Committee. If a related party transaction is identified during the year, it is reported promptly to the Audit Committee. The Audit Committee
reviews and considers all relevant information available to it about each related party transaction. A related party transaction is approved or ratified only if the Audit Committee determines that it is in, or is not inconsistent with, our best
interests and those of our stockholders and is in compliance with the Code of Ethics.

We did not have any related party transactions
during 2015.

DIRECTOR INDEPENDENCE

Our Board of Directors undertook a review of the independence of each director and considered whether any director has a material relationship
with us that could compromise his ability to exercise independent judgment in carrying out his responsibilities. As a result of this review, our Board of Directors determined that Messrs. Aquilano, Caldwell, Mikolajczyk and Spencer,
representing four of our five directors, are independent directors as defined under the rules of the NASDAQ Stock Market, constituting a majority of our Board of Directors as required by the rules of the NASDAQ Stock Market.
