Important Notice Regarding the Availability of Proxy Materials for the Stockholder Meeting To Be Held on June 18, 2015.15, 2016.

These proxy materials, which include the notice of annual meeting, this proxy statement, and our 20142015 Annual Report for the fiscal year ended December 31, 2014,2015, are available atwww.cstproxy.com/questrmg/20152016.

Stockholders Entitled to Vote; Record Date; How to Vote

Stockholders of record at the close of business on April 20, 2015,18, 2016, which we have set as the record date, are entitled to notice of and to vote at the meeting. On the record date, there were outstanding 111,657,804118,678,225 shares of our common stock. Each stockholder voting at the meeting, either in person or by proxy, may cast one vote per share of common stock held on all matters to be voted on at the meeting.

If, on April 20, 2015,18, 2016, your shares were registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, then you are a stockholder of record. As a stockholder of record, you may vote in person at the meeting. Alternatively, you may vote by using the accompanying proxy card. Whether or not you plan to attend the meeting, we urge you to vote by filling out and returning the enclosed proxy card as instructed on the enclosed proxy card to ensure your vote is counted. Even if you have submitted a proxy before the meeting, you may still attend the meeting and vote in person.

If, on April 20, 2015,18, 2016, your shares were held in an account at a brokerage firm, bank, or similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the meeting. As a beneficial owner, you have the right to direct your broker, bank, or other nominee on how to vote the shares in your account. You should have received voting instructions with these

proxy materials from that organization rather than from us. You should follow the instructions provided by that organization to submit your proxy. You are also invited to attend the meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the meeting unless you obtain a “legal proxy” from the broker, bank, or other nominee that holds your shares giving you the right to vote the shares at the meeting.

Quorum; Required Vote; Broker Non-Votes and Abstentions

The presence, in person or by proxy, of the holders of a majority of the total number of shares of common stock entitled to vote constitutes a quorum for the transaction of business at the meeting. Votes cast in person or by proxy at the meeting will be tabulated by the election inspector appointed for the meeting, who will determine whether a quorum is present.

Assuming that a quorum is present, the three persons receiving the largest number of “for” votes of our common stock present in person or by proxy at the meeting and entitled to vote (a plurality) will be elected directors. Stockholders do not have the right to cumulate their votes in the election of directors. The affirmative vote of a majority of the votes cast will be required to authorize our Board of Directors to amend our articles of incorporation to effect an up to 1-for-10 reverse stock split of our common stock and to ratify the appointment of Semple, Marchal and Cooper, LLP, an independent registered public accounting firm, as the independent registered public accountant of our company for the fiscal year ending December 31, 2015.2016. The advisory vote on the compensation of our named executive officers for fiscal 2014,2015, or say-on-pay, is non-binding, but the Board of Directors will consider the input of stockholders based on a majority of votes cast for the say-on-pay proposal.

Brokers, banks, or other nominees that hold shares of common stock in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion if permitted by the stock exchange or other organization of which they are members. Brokers, banks, and other nominees are permitted to vote the beneficial owner’s proxy in their own discretion as to certain “routine” proposals when they have not received instructions from the beneficial owner, such as the ratification of the appointment of Semple, Marchal and Cooper, LLP as the independent registered public accountant of our company for the fiscal year ending December 31, 2015.2016. If a broker, bank, or other nominee votes such “uninstructed” shares for or against a “routine” proposal, those shares will be counted towards determining whether or not a quorum is present and are considered entitled to vote on the “routine” proposals. However, where a proposal is not “routine,” a broker, bank, or other nominee is not permitted to exercise its voting discretion on that proposal without specific instructions from the beneficial owner. These non-voted shares are referred to as “broker non-votes” when the nominee has voted on other non-routine matters with authorization or voted on routine matters. These shares will be counted towards determining whether or not a quorum is present, but will not be considered entitled to vote on the “non-routine” proposals.

Please note that brokers, banks, and other nominees may not use discretionary authority to vote shares on the election of directors, the say-on-pay proposal, or the say-on-pay proposal.proposal to authorize our Board of Directors to amend our articles of incorporation to effect an up to 1-for-10 reverse stock split of our common stock. For your vote to be counted in the election of directors, or the say-on-pay proposal, or the proposal to authorize our Board of Directors to amend our articles of incorporation to effect an up to 1-for-10 reverse stock split of our common stock, you will need to communicate your voting decisions to your broker, bank, or other nominee before the date of the meeting.

As provided in our bylaws, a majority of the votes cast means that the number of votes cast “for” a proposal exceeds the number of votes cast “against” that proposal. Because abstentions and broker non-votes do not represent votes cast “for” or “against” a proposal, broker non-votes and abstentions will have no effect on the election of directors, the say-on-pay proposal, the proposal to authorize our Board of Directors to amend our articles of incorporation to effect an up to 1-for-10 reverse stock split of our common stock, or the proposal to ratify the appointment of Semple, Marchal and Cooper, LLP as the independent registered public accountant of our company for the fiscal year ending December 31, 2015,2016, as each such proposal is determined by reference to the votes actually cast by the shares present in person or by proxy at the meeting and entitled to vote.

Voting of Proxies

When a proxy is properly executed and returned, the shares it represents will be voted at the meeting as directed. Except as provided above under “Quorum; Required Vote; Broker Non-Votes and Abstentions,” if no specification is indicated, the shares will be voted (1) “for” the election of each of the three director nominees set forth in this proxy statement, (2) “for” the approval of the compensation of our named executive officers for fiscal 2014,2015, (3) “for” the authorization of our Board of Directors to amend our articles of incorporation to effect an up to 1-for-10 reverse stock split of our common stock, and (3)(4) “for” the ratification of the appointment of Semple, Marchal and Cooper, LLP as the independent registered public accountant of our company for the fiscal year ending December 31, 2015.2016. If any other matter is properly presented at the meeting, the individuals specified in the proxy will vote your shares using their best judgment.

Revocability of Proxies

Any person giving a proxy may revoke the proxy at any time before its use by delivering to us either a written notice of revocation or a duly executed proxy bearing a later date or by attending the meeting and voting in person. Attendance at the meeting will not cause your previously granted proxy to be revoked unless you specifically so request.

Solicitation

We will bear the cost of this solicitation. In addition, we may reimburse brokerage firms and other persons representing beneficial owners of shares for expenses incurred in forwarding solicitation materials to such beneficial owners. Proxies also may be solicited by certain of our directors and officers, personally or by telephone or e-mail, without additional compensation.

Annual Report and Other Matters

Our 20142015 Annual Report to Stockholders, which was made available to stockholders with or preceding this proxy statement, contains financial and other information about our company, but is not incorporated into this proxy statement and is not to be considered a part of these proxy materials or subject to Regulations 14A or 14C or to the liabilities of Section 18 of the Securities Exchange Act of 1934, as amended, or the Exchange Act. The information contained in the “Report of the Audit Committee” shall not be deemed “filed” with the SEC or subject to Regulations 14A or 14C or to the liabilities of Section 18 of the Exchange Act.

We will provide, without charge, a copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 20142015 as filed with the SEC to each stockholder of record as of the record date that requests a copy in writing. Any exhibits listed in our Annual Report on Form 10-K also will be furnished upon request at the actual expense we incur in furnishing such exhibits. Any such requests should be directed to our Secretary at the address of our executive offices set forth in this proxy statement.

Our Board of Directors has also adopted Corporate Governance Guidelines, a Code of Conduct, and a Code of Ethics for the CEO and Senior Financial Officers. We post on our website, atwww.qrhc.com, the charters of our Audit, Compensation, and Nominations and Corporate Governance Committees; our Corporate Governance Guidelines, Code of Conduct, and Code of Ethics for the CEO and Senior Financial Officers, and any amendments or waivers thereto; and any other corporate governance materials specified by SEC regulations. These documents are also available in print to any stockholder requesting a copy in writing from our Secretary at the address of our executive offices set forth in this proxy statement.

Executive Sessions

We regularly schedule executive sessions in which independent directors meet without the presence or participation of management. The Chairman of our Board of Directors serves as the presiding director of such executive sessions.

Board Committees

Our bylaws authorize our Board of Directors to appoint from among its members one or more committees consisting of one or more directors. Our Board of Directors has established an Audit Committee, a Compensation Committee, and a Nominations and Corporate Governance Committee, each consisting entirely of independent directors as “independence” is defined by the listing standards of Nasdaq and by the SEC.

The Audit Committee

The purpose of the Audit Committee includes overseeing the accounting and financial reporting processes of our company and audits of the financial statements of our company and providing assistance to our Board of Directors with respect to its oversight of the integrity of our company’s financial statements, our company’s

compliance with legal and regulatory requirements, the independent registered public accountant’s qualifications and independence, and the performance of our company’s independent registered public accountant. The primary responsibilities of the Audit Committee are set forth in its charter and include various matters with respect to the oversight of our company’s accounting and financial reporting process and audits of the financial statements of our company on behalf of our Board of Directors. The Audit Committee also selects the independent registered public accountant to conduct the annual audit of the financial statements of our company; reviews the proposed scope of such audit; reviews accounting and financial controls of our company with the independent registered public accountant and our financial accounting staff; and reviews and approves any transactions between us and our directors, officers, and their affiliates.

The Audit Committee currently consists of Messrs. Golden, Miller, and GoldenKnittel and Ms. Wadecki. Our Board of Directors has determined that each of Messrs. Golden, Miller, and GoldenKnittel and Ms. Wadecki, whose backgrounds are detailed above, qualifies as an “audit committee financial expert” in accordance with applicable rules and regulations of the SEC. Mr. Miller chairs the Audit Committee.

The Compensation Committee

The purpose of the Compensation Committee includes determining, or, when appropriate, recommending to our Board of Directors for determination, the compensation of the Chief Executive Officer and other executive officers of our company and discharging the responsibilities of our Board of Directors relating to compensation programs of our company in light of the goals and objectives of our compensation program for that year. As part of its responsibilities, the Compensation Committee evaluates the performance of our Chief Executive Officer and, together with our Chief Executive Officer, assesses the performance of our other executive officers. The Compensation Committee is entitled to delegate its responsibilities to a subcommittee of the Compensation Committee, which complies with the applicable rules and regulations of the Nasdaq Stock Market, the SEC, and other regulatory bodies. From time to time the Compensation Committee retains the services of independent compensation consultants to review a wide variety of factors relevant to executive compensation, trends in executive compensation, and the identification of relevant peer companies. The Compensation Committee makes all determinations regarding the engagement, fees, and services of its compensation consultants, and its compensation consultants report directly to the Compensation Committee. The Compensation Committee currently consists of Messrs. Golden,Knittel, Miller, and Saltz. Mr. GoldenSaltz chairs the Compensation Committee. Mr. Golden served on the Compensation Committee for a portion of fiscal 2015, but resigned from the Compensation Committee upon his appointment as Interim Chief Executive Officer of our company in October 2015.

The Nominations and Corporate Governance Committee

The purpose of the Nominations and Corporate Governance Committee includes the selection or recommendation to our Board of Directors of nominees to stand for election as directors at each election of directors, the oversight of the selection and composition of committees of our Board of Directors, the oversight of the evaluations of our Board of Directors and management, and the development and recommendation to our Board of Directors of a set of corporate governance principles applicable to our company. The Nominations and Corporate Governance Committee currently consists of Messrs. Golden, Knittel, and Miller and Ms. Wadecki. Ms. Wadecki chairs the Nominations and Corporate Governance Committee.

The Nominations and Corporate Governance Committee will consider persons recommended by stockholders for inclusion as nominees for election to our Board of Directors if the information required by our bylaws is submitted in writing in a timely manner addressed and delivered to our Secretary at the address of our executive offices set forth in this proxy statement. The Nominations and Corporate Governance Committee identifies and evaluates nominees for our Board of Directors, including nominees recommended by stockholders, based on numerous factors it considers appropriate, some of which may include strength of character, mature

judgment, career specialization, relevant technical skills, diversity, and the extent to which the nominee would fill a present need on our Board of Directors.

Risk Assessment of Compensation Policies and Practices

We have assessed the compensation policies and practices with respect to our employees, including our executive officers, and have concluded that they do not create risks that are reasonably likely to have a material adverse effect on our company.

Board’s Role in Risk Oversight

Risk is inherent in every business. As is the case in virtually all businesses, we face a number of risks, including operational, economic, financial, legal, regulatory, and competitive risks. Our management is responsible for the day-to-day management of the risks we face. Our Board of Directors, as a whole and through its committees, has responsibility for the oversight of risk management.

In its oversight role, our Board of Directors’ involvement in our business strategy and strategic plans plays a key role in its oversight of risk management, its assessment of management’s risk appetite, and its determination of the appropriate level of enterprise risk. Our Board of Directors receives updates at least quarterly from senior management and periodically from outside advisors regarding the various risks we face, including operational, economic, financial, legal, regulatory, and competitive risks. Our Board of Directors also reviews the various risks we identify in our filings with the SEC as well as risks relating to various specific developments, such as acquisitions, debt and equity placements, and new service offerings.

Our board committees assist our Board of Directors in fulfilling its oversight role in certain areas of risk. Pursuant to its charter, the Audit Committee oversees the financial and reporting processes of our company and the audit of the financial statements of our company and provides assistance to our Board of Directors with respect to the oversight and integrity of the financial statements of our company, our company’s compliance with legal and regulatory requirements, the independent registered public accountant’s qualification and independence, and the performance of our independent registered public accountant. The Compensation Committee considers the risk of our compensation policies and practices and endeavors to assure that it is not reasonably likely that our compensation plans and policies would have a material adverse effect on our company. Our Nominations and Corporate Governance Committee oversees governance related risk, such as board independence, conflicts of interests, and management and succession planning.

Board Diversity

We seek diversity in experience, viewpoint, education, skill, and other individual qualities and attributes to be represented on our Board of Directors. We believe directors should have various qualifications, including individual character and integrity; business experience; leadership ability; strategic planning skills, ability, and experience; requisite knowledge of our industry and finance, accounting, and legal matters; communications and interpersonal skills; and the ability and willingness to devote time to our company. We also believe the skill sets, backgrounds, and qualifications of our directors, taken as a whole, should provide a significant mix of diversity in personal and professional experience, background, viewpoints, perspectives, knowledge, and abilities. Nominees are not to be discriminated against on the basis of race, religion, national origin, sex, sexual orientation, disability, or any other basis proscribed by law. The assessment of prospective directors is made in the context of the perceived needs of our Board of Directors from time to time.

All of our directors have held high-level positions in business or professional service firms and have experience in dealing with complex issues. We believe that all of our directors are individuals of high character and integrity, are able to work well with others, and have committed to devote sufficient time to the business and affairs of our company. In addition to these attributes, the description of each director’s background set forth

above indicates the specific qualifications, skills, perspectives, and experience necessary to conclude that each individual should continue to serve as a director of our company.

Board Leadership Structure

We believe that effective board leadership structure can depend on the experience, skills, and personal interaction between persons in leadership roles as well as the needs of our company at any point in time. Our Corporate Governance Guidelines support flexibility in the structure of our Board of Directors by not requiring the separation of the roles of Chief Executive Officer and Chairman of the Board.

We currently maintain separate roles between the Chief Executive Officer and Chairman of the Board in recognition of the differences between the two responsibilities. Our Chief Executive Officer is responsible for setting our strategic direction and day-to-day leadership and performance of our company. The Chairman of the Board provides input to the Chief Executive Officer, sets the agenda for board meetings, and presides over meetings of the full Board of Directors as well as executive sessions of the Board of Directors.

Clawback Policy

We adopted a clawback policy onin May 21, 2014. In the event we are required to prepare an accounting restatement of our financial results as a result of a material noncompliance by us with any financial reporting requirement under the federal securities laws, we will have the right to use reasonable efforts to recover from any current or former executive officers who received incentive compensation (whether cash or equity) from us during the three-year period preceding the date on which we were required to prepare the accounting restatement, any excess incentive compensation awarded as a result of the misstatement. This policy is administered by the Compensation Committee of our Board of Directors. The policy is effective for financial statements for periods beginning on or after January 1, 2014. Once final rules are adopted by the SEC regarding the clawback requirements under the Dodd-Frank Wall Street Reform and Consumer Protection Act, we will review this policy and make any amendments necessary to comply with the new rules.

Compensation Committee Interlocks and Insider Participation

During our fiscal year ended December 31, 2014,2015, Messrs. Golden, Knittel, Miller, and Saltz served on our Compensation Committee. Messrs. GoldenKnittel, Miller, and MillerSaltz had no material contractual or other relationships with us during such transition period except as directors and equity holders. See “Certain Relationships and Related Transactions” for additional disclosure regarding Mr. Saltz.Golden resigned from the Compensation Committee upon his appointment as Interim Chief Executive Officer of our company in October 2015.

Board and Committee Meetings

Our Board of Directors held a total of sevenfive meetings during the fiscal year ended December 31, 2014.2015. During the fiscal year ended December 31, 2014,2015, the Audit Committee held sixnine meetings; the Compensation Committee held three meetings; and the Nominations and Corporate Governance Committee held threefive meetings. No director attended fewer than 75% of the aggregate of (i) the total number of meetings of our Board of Directors and (ii) the total number of meetings held by all committees of our Board of Directors on which he or she was a member.

Annual Meeting Attendance

We encourage each of our directors to attend each annual meeting of stockholders. To that end, and to the extent reasonably practicable, we regularly schedule a meeting of our Board of Directors on the same day as our annual meeting of stockholders. All of our directors attended our 20142015 Annual Meeting of Stockholders.

Communications with Directors

Stockholders and other interested parties may communicate with our Board of Directors or specific members of our Board of Directors, including our independent directors and the members of our various board committees, by submitting a letter addressed to the Board of Directors of Quest Resource Holding Corporation c/o any specified individual director or directors at the address of our executive offices set forth in this proxy statement.

Our stockholders approved the 2012 Plan on October 18, 2013. The purpose of the 2012 Plan is to assist us and our subsidiaries and other designated affiliates, which we refer to as “Related Entities,” in attracting, motivating, retaining, and rewarding high-quality executives and other employees, officers, directors, and individual consultants who provide services to us or our Related Entities, by enabling such persons to acquire or increase a proprietary interest in our company in order to strengthen the mutuality of interests between such persons and our stockholders, and providing such persons with performance incentives to expend their maximum efforts in the creation of stockholder value. As of December 31, 2014, there were outstanding issued but unexercised options under the 2012 Plan to acquire 3,217,500 shares of our common stock at a weighted average exercise price of $2.34 per share.

As of April 18, 2016, 3,960,959 shares remained available for future grant under the 2012 Plan. The material features of the 2012 Plan are outlined below.

Awards. The 2012 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, RSUs, bonus stock, dividend equivalents, other stock-based awards, and performance awards that may be settled in cash, stock, or other property.

Shares Available for Awards. A total of 7,500,000 shares of our common stock are reserved and available for delivery under the 2012 Plan. Any shares under the 2012 Plan that are not issued because the awards terminate without the issuance of shares, or because of the withholding of shares to pay taxes or the exercise price of an award, will be available for issuance under the 2012 Plan.

Limitations on Awards. The 2012 Plan imposes individual limitations on certain awards, in part to comply with Section 162(m) of the Internal Revenue Code of 1986, as amended, or the Code. In any fiscal year during any part of which the 2012 Plan is in effect, no participant may be granted (1) stock options and/or stock appreciation rights with respect to more than 1,000,000 shares of our

common stock, or (2) restricted stock, RSUs, performance awards and/or other stock-based awards that are intended to qualify as “performance-based compensation” exempt from the deduction limitations imposed under Section 162(m) of the Code that may be settled by the issuance of more than 1,000,000 shares of our common stock, in each case, subject to adjustment in certain circumstances. The maximum amount of cash and the fair market value of property other than shares of our common stock that may be payable to any one participant in settlement of any restricted stock award, RSU award, performance award, and/or other stock-based award that are intended to qualify as “performance-based compensation” exempt from the deduction limitations imposed under Section 162(m) of the Code, is (i) $2,000,000 with respect to any 12 month performance period (not prorated for any performance period that is less than 12 months), and (ii) with respect to any performance period that is more than 12 months, $5,000,000.

Notwithstanding any other provision of the 2012 Plan to the contrary, the aggregate grant date fair value (computed as of the date of grant in accordance with applicable financial accounting rules) of all awards granted to any outside director during any fiscal year will not exceed $2,000,000 or 750,000 shares of our common stock.

Subject to adjustment as provided in the 2012 Plan, the maximum aggregate number of shares of our common stock that may be delivered under the 2012 Plan as a result of the exercise of incentive stock options granted under the 2012 Plan is 7,500,000 shares.

Except as otherwise provided in the 2012 Plan, the committee (as defined below) will not be permitted to (1) lower the exercise price of a stock option or the grant price of a stock appreciation right after it is granted, (2) cancel a stock option or stock appreciation right when the exercise or grant price exceeds the fair market value of the underlying shares of our common stock in exchange for cash or another award, (3) cancel a stock option or stock appreciation right in exchange for a stock option or stock appreciation right with an exercise or grant price that is less than the exercise or grant price of the original stock option or stock appreciation right, or (4) take any other action with respect to a stock option or stock appreciation right that may be treated as a repricing, without approval of our stockholders.

Capitalization Adjustments. In the event that any extraordinary dividend or other distribution, recapitalization, forward or reverse split, reorganization, merger, consolidation, spinoff, combination, repurchase, share exchange, liquidation, dissolution, or other similar corporate transaction or event affects our common stock, then the committee (as defined below) will substitute, exchange, or adjust any or all of the following in such manner as it deems equitable: (1) the kind and number of shares available under the 2012 Plan; (2) the kind and number of shares subject to limitations on awards described in the preceding section; (3) the kind and number of shares subject to all outstanding awards; (4) the exercise price, grant price, or purchase price relating to any award; and (5) any other affected terms of awards.

Eligibility. The persons eligible to receive awards under the 2012 Plan consist of officers, directors, employees, and consultants who are natural persons providing bona fide services to us or our Related Entities. However, incentive stock options may be granted under the 2012 Plan only to our employees, including our officers who are employees.

Administration. The 2012 Plan will be administered by the compensation committee of our Board of Directors or a subcommittee thereof formed by the compensation committee, except to the extent our Board of Directors elects to administer the 2012 Plan (subject to limitations described in the 2012 Plan). The committee members will be (i) “non-employee directors” as defined by Rule 16b-3 under the Exchange Act, unless administration of the 2012 Plan by “non-employee directors” is not then required in order for exemptions under Rule 16b-3 to apply to transactions under the 2012 Plan, (ii) “outside directors” within the meaning of Section 162(m) of the Code, and (iii) “independent” as defined by the listing market on which shares of our common stock are listed for trading. Subject to the terms of the 2012 Plan, the committee is authorized to select eligible persons to receive awards, determine the type and number of awards to be granted and the number of shares of our common stock to which awards will relate, specify times at which awards will be exercisable or may be settled (including performance conditions that may be required as a condition thereof), set other terms and conditions of awards, prescribe forms of award agreements, interpret and specify rules and regulations relating to the 2012 Plan, and make all other determinations that may be necessary or advisable for the administration of the 2012 Plan. The committee may amend the terms of outstanding awards, in its discretion. Any amendment that adversely affects the rights of the award recipient, however, must receive the approval of such recipient.

Stock Options and Stock Appreciation Rights. The committee is authorized to grant stock options, including both incentive stock options and non-qualified stock options. In addition, the committee is authorized to grant stock appreciation rights, which entitle the participant to receive the appreciation of our common stock between the grant date and the exercise date of the stock appreciation right. The committee determines the exercise price per share subject to an option and the grant price of a stock appreciation right; however, the per share exercise price of an option or stock appreciation right must not be less than the fair market value of a share of our common stock on the grant date. The committee generally will fix the maximum term of each option or stock appreciation right, the times at which each option or stock appreciation right will be exercisable, and provisions requiring forfeiture of unexercised options or stock appreciation rights at or following termination of employment or service, except that no option or stock appreciation right may have a term exceeding 10 years. Options may be exercised by payment of the exercise price in any form of legal consideration specified by the committee, including cash, shares (including cancellation of a portion of the shares subject to the award), outstanding awards, or other property having a fair market value equal to the exercise price. Options may also be exercisable in connection with a broker-assisted sales transaction, or a cashless exercise, as determined by the committee. The committee determines methods of exercise and settlement and other terms of the stock appreciation rights.

Restricted Stock and Restricted Stock Units. The committee is authorized to grant restricted stock and RSUs. Restricted stock is a grant of shares of our common stock, which may not be sold or disposed of and which may be forfeited in the event of certain terminations of employment or service prior to the end of a restricted period specified by the committee. A participant granted restricted stock generally has all of the rights of one of our stockholders, unless otherwise determined by the committee. An award of RSUs confers upon a participant the right to receive shares of our common stock at the end of a specified period or upon achievement of performance goals and may be subject to possible forfeiture of the award in the event of certain terminations of employment prior to the end of a specified period. Prior to settlement, an RSU award carries no voting or dividend rights or other rights associated with share ownership, although dividend equivalents may be granted, as discussed below. The committee determines all of the terms of the restricted stock and RSU awards subject to the terms of the 2012 Plan.

Dividend Equivalents. The committee is authorized to grant dividend equivalents conferring on participants the right to receive, currently or on a deferred basis, cash, shares of our common stock, other awards, or other property equal in value to dividends paid on a specific number of shares of our common stock or other periodic payments. Dividend equivalents may be granted alone or in connection with another award, other than a stock option or stock appreciation right award, may be paid currently or on a deferred basis and, if deferred, may be deemed to have been reinvested in additional shares of our common stock, awards, or otherwise as specified by

the committee. Notwithstanding the foregoing, dividend equivalents credited in connection with an award that vests based on the achievement of performance goals will be subject to restrictions and risk of forfeiture to the same extent as the award with respect to which such dividend equivalents have been credited. The committee determines all of the terms of the dividend equivalent awards subject to the terms of the 2012 Plan.

Bonus Stock and Awards in Lieu of Cash Obligations. The committee is authorized to grant shares of our common stock as a bonus free of restrictions for services performed for our company or to grant shares of our common stock or other awards in lieu of our obligations to pay cash under the 2012 Plan or other plans or compensatory arrangements, subject to such terms as the committee may specify.

Other Stock Based Awards. The committee is authorized to grant awards under the 2012 Plan that are denominated or payable in, valued by reference to, or otherwise based on or related to shares of our common stock. The committee determines the terms and conditions of such awards.

Performance Awards. The committee is authorized to grant performance awards to participants on terms and conditions established by the committee. The performance criteria to be achieved during any performance period and the length of the performance period will be determined by the committee upon the grant of the performance award. Performance awards may be valued by reference to a designated number of shares of our common stock (in which case they are referred to as performance shares) or by reference to a designated amount of property including cash (in which case they are referred to as performance units). Performance awards may be settled by delivery of cash, shares of our common stock or other property, or any combination thereof, as determined by the committee.

The provisions that are intended to qualify awards as “performance based compensation” not subject to the limitation on tax deductibility by us under Section 162(m) of the Code will apply to any restricted stock award, RSU award, performance award, or other stock-based award if it is granted to a participant who is, or is likely to be, as of the end of the tax year in which we would claim a tax deduction in connection with such award, a “covered employee” (as defined below) and is intended to qualify as “performance-based compensation” not subject to the limitation on tax deductibility. The term “covered employee” means our chief executive officer and each other person whose compensation is required to be disclosed in our filings with the SEC by reason of that person being among the three highest compensated officers of our company (other than our principal financial officer) as of the end of a taxable year. If and to the extent required under Section 162(m) of the Code, any power or authority relating to an award intended to qualify under Section 162(m) of the Code is to be exercised by the committee and not our Board of Directors.

If an award is subject to the provisions of the 2012 Plan that are intended to qualify awards as “performance based compensation” not subject to the limitation on tax deductibility by us under Section 162(m) of the Code, then the payment or distribution thereof or the lapsing of restrictions thereon and the distribution of cash, shares of our common stock or other property pursuant thereto, as applicable, will be contingent upon achievement of one or more objective performance goals. Performance goals will be objective and will otherwise meet the requirements of Section 162(m) of the Code and regulations thereunder, including the requirement that the level or levels of performance targeted by the committee result in the achievement of performance goals being “substantially uncertain.” One or more of the following business criteria for our company, on a consolidated basis, and/or for Related Entities, or for business or geographical units of our company and/or a Related Entity (except with respect to the total stockholder return and earnings per share criteria), will be used by the committee in establishing performance goals for such awards: (1) total stockholder return; (2) such total stockholder return as compared to total return (on a comparable basis) of a publicly available index such as, but not limited to, the Standard & Poor’s 500 Stock Index or the S&P Specialty Retailer Index; (3) net income; (4) pretax earnings; (5) earnings before all or some of the following items: interest, taxes, depreciation, amortization, stock-based compensation, ASC 718 expense, or any extraordinary or special items; (6) pretax operating earnings after interest expense and before bonuses, service fees, and extraordinary or special items; (7) operating margin; (8) earnings per share; (9) return on equity; (10) return on capital; (11) return on investment; (12) operating earnings; (13) working capital or inventory; (14) operating earnings before the expense for share based awards;

and (15) ratio of debt to stockholders’ equity. Any of the above goals may be determined on an absolute or relative basis or as compared to the performance of a published or special index deemed applicable by the committee including, but not limited to, the Standard & Poor’s 500 Stock Index or a group of companies that are comparable to our company. In determining the achievement of the performance goals, unless otherwise specified by the committee at the time the performance goals are set, the committee will exclude the impact of (i) restructurings, discontinued operations, and extraordinary items (as defined pursuant to generally accepted accounting principles), and other unusual or non-recurring charges, (ii) change in accounting standards required by generally accepted accounting principles; or (iii) such other exclusions or adjustments as the committee specifies at the time the award is granted.

The committee may, in its discretion, reduce the amount of a settlement otherwise to be made in connection with awards subject to the provisions of the 2012 Plan that are intended to qualify awards as “performance based compensation” not subject to the limitation on tax deductibility by us under Section 162(m) of the Code, but may not exercise discretion to increase any such amount payable to a covered employee in respect of an award subject to such provisions of the 2012 Plan.

Other Terms of Awards. Awards may be settled in the form of cash, shares of our common stock, other awards, or other property in the discretion of the committee. Awards under the 2012 Plan are generally granted without a requirement that the participant pay consideration in the form of cash or property for the grant (as distinguished from the exercise), except to the extent required by law. The committee may require or permit participants to defer the settlement of all or part of an award in accordance with such terms and conditions as the committee may establish, including payment or crediting of interest or dividend equivalents on deferred amounts, and the crediting of earnings, gains, and losses based on deemed investment of deferred amounts in specified investment vehicles. The committee is authorized to place cash, shares of our common stock, or other property in trusts or make other arrangements to provide for payment of our obligations under the 2012 Plan. The committee may condition any payment relating to an award on the withholding of taxes and may provide that a portion of any shares of our common stock or other property to be distributed will be withheld (or previously acquired shares of our common stock or other property be surrendered by the participant) to satisfy withholding and other tax obligations. Awards granted under the 2012 Plan generally may not be pledged or otherwise encumbered and are not transferable except by will or by the laws of descent and distribution, or to a designated beneficiary upon the participant’s death, except that the committee may, in its discretion, permit transfers of awards subject to any applicable legal restrictions.

Acceleration of Vesting; Change in Control. Upon the occurrence of a “change in control,” as defined in the 2012 Plan, any restrictions, deferral of settlement, and forfeiture conditions applicable to an award will lapse, and any performance goals and conditions applicable to an award will be deemed to have been met, as of the time of the change in control. Notwithstanding, unless the committee otherwise determines in a specific instance, each outstanding award will not be accelerated as described in foregoing sentence, if either (i) our company is the surviving entity in the change in control and the award continues to be outstanding after the change in control on substantially the same terms and conditions as were applicable immediately prior to the change in control or (ii) the successor company assumes or substitutes for the applicable award, as determined in accordance with the 2012 Plan. If and to the extent provided in an award agreement and on such terms and conditions as may be set forth in an award agreement, in the event a participant’s employment is terminated without “cause” by us or any Related Entity or by such successor company or by the participant for “good reason,” both terms as defined in the 2012 Plan, within 24 months following such change in control, each award held by such participant at the time of the change in control will be accelerated as described above.

Clawback of Benefits. We may (i) cause the cancellation of any award, (ii) require reimbursement of any award by a participant or beneficiary, and (iii) effect any other right of recoupment of equity or other compensation provided under the 2012 Plan or otherwise in accordance with any company policies that currently exist or that may from time to time be adopted or modified in the future by us and/or applicable law, or a Clawback Policy. In addition, a participant may be required to repay to our company certain previously paid compensation, whether provided under the 2012 Plan or an award agreement or otherwise, in accordance with

any Clawback Policy. By accepting an award, a participant is also agreeing to be bound by any existing or future Clawback Policy adopted

by us, or any amendments that may from time to time be made to the Clawback Policy in the future by us in our discretion (including without limitation any Clawback Policy adopted or amended to comply with applicable laws or stock exchange requirements) and is further agreeing that all of the participant’s award agreements may be unilaterally amended by us, without the participant’s consent, to the extent that we in our discretion determine to be necessary or appropriate to comply with any Clawback Policy.

If the participant, without our consent, while employed by or providing services to us or any Related Entity or after termination of such employment or service, violates a non-competition, non-solicitation or non-disclosure covenant or agreement or otherwise engages in activity that is in conflict with or adverse to the interest of our company or any Related Entity, as determined by the committee in its sole discretion, then (i) any outstanding, vested or unvested, earned or unearned portion of the award may, at the committee’s discretion, be canceled and (ii) the committee, in its discretion, may require the participant or other person to whom any payment has been made or shares of our common stock or other property have been transferred in connection with the award to forfeit and pay over to us, on demand, all or any portion of the gain (whether or not taxable) realized upon the exercise of any stock option or stock appreciation right and the value realized (whether or not taxable) on the vesting or payment of any other award during the time period specified in the award agreement or otherwise specified by the committee.

Amendment and Termination. Our Board of Directors may amend, alter, suspend, discontinue, or terminate the 2012 Plan or the committee’s authority to grant awards without further stockholder approval, except stockholder approval will be obtained for any amendment or alteration if such approval is deemed necessary and advisable by our Board of Directors or any amendment for which stockholder approval is required by law or the primary stock exchange on which our common stock trades. The 2012 Plan will terminate at the earliest of (i) such time as no shares of our common stock remain available for issuance under the 2012 Plan, (ii) termination of the 2012 Plan by our Board of Directors, or (c) the tenth anniversary of the effective date of the 2012 Plan, which was October 18, 2012. Except as otherwise permitted by the 2012 Plan or award agreement, amendments to the 2012 Plan or any award require the consent of the affected participant if the amendment has a material adverse effect on the participant’s previously granted and outstanding awards.

The following table sets forth information as of December 31, 20142015 with respect to our common stock that may be issued under our incentive compensation plans and under other option grants.

REPORT OF THE AUDIT COMMITTEE

The Board of Directors has appointed an Audit Committee, consisting of threefour independent directors. All of the members of the Audit Committee are “independent” of our company and management, as independence is defined in applicable rules of Nasdaq and the SEC.

The purpose of the Audit Committee is to assist the oversight of our Board of Directors in the integrity of the financial statements of our company, our company’s compliance with legal and regulatory matters, the independent registered public accountant’s qualifications and independence, and the performance of our company’s independent registered public accountant. The primary responsibilities of the committee include overseeing our company’s accounting and financial reporting process and audits of the financial statements of our company on behalf of the Board of Directors.

Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal controls. The independent registered public accountant is responsible for auditing the financial statements and expressing an opinion on the conformity of those audited financial statements with accounting principles generally accepted in the United States.

In fulfilling its oversight responsibilities, the committee reviewed the audited financial statements with management and the independent registered public accountant. The committee discussed with the independent registered public accountant the matters required to be discussed by the Public Company Accounting Oversight Board. This included a discussion of the independent registered public accountant’s judgments as to the quality, not just the acceptability, of our company’s accounting principles and such other matters as are required to be discussed with the committee under generally accepted auditing standards. In addition, the committee received from the independent registered public accountant written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accountant’s communications with the committee concerning independence. The committee also discussed with the independent registered public accountant theirits independence from management and our company, including the matters covered by the written disclosures and letter provided by the independent registered public accountant.

The committee discussed with the independent registered public accountant the overall scope and plans for its audit. The committee met with the independent registered public accountant, with and without management present, to discuss the results of the examinations, its evaluations of our company, the internal controls, and the overall quality of the financial reporting. The committee held sixnine meetings during the fiscal year ended December 31, 2014.2015.

Based on the reviews and discussions referred to above, the committee recommended to the Board of Directors, and the Board of Directors approved, that the audited financial statements be included in the Annual Report on Form 10-K for the fiscal year ended December 31, 20142015 for filing with the SEC.

The report has been furnished by the Audit Committee of our Board of Directors.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires our directors, officers, and persons that own more than 10 percent of a registered class of our company’s equity securities to file reports of ownership and changes in ownership with the SEC. Directors, officers, and greater than 10 percent stockholders are required by SEC regulations to furnish our company with copies of all Section 16(a) forms they file.

Based solely upon our review of the copies of such forms received by us during the fiscal year ended December 31, 2014,2015, and written representations that no other reports were required, we believe that each person who, at any time during such fiscal year, was a director, officer, or beneficial owner of more than 10 percent of our common stock complied with all Section 16(a) filing requirements during such fiscal year ended December 31, 2014,2015, except that the followinga Form 4s were late: the Form 4s4 was not filed by Mr. Monheit, Mr. Saltz, and Stockbridge Enterprises, L.P.Colton R. Melby, then a 10 percent stockholder, to report a disposition of 617,127 shares of our common stock on February 5, 2014; the Form 4 filed by Mr. Forte on April 28, 2014; the Form 4 filed by Mr. Melby on October 17, 2014; and the Form 4 filed by Mr. Cheney on November 19, 2014.June 15, 2015.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information regarding the beneficial ownership of shares as of April 20, 201518, 2016 by (1) each director, nominee for director, and named executive officer of our company, (2) all directors and executive officers of our company as a group, and (3) each person known by us to own more than 5% of our common stock.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Unless delegated to the Compensation Committee by our Board of Directors, the Audit Committee charter requires the Audit Committee to review and approve all related party transactions and to review and make recommendations to the full Board of Directors, or approve, any contracts or other transactions with current or former executive officers of our company, including consulting arrangements, employment agreements, change-in-control agreements, termination arrangements, and loans to employees made or guaranteed by our company. We have a policy that we will not enter into any such transaction unless the transaction is determined by our disinterested directors to be fair to us or is approved by our disinterested directors or by our stockholders. Any determination by our disinterested directors is based on a review of the particular transaction, applicable laws and regulations, and policies of our company (including those set forth above under “Corporate Governance” or published on our website). As appropriate, the disinterested directors of the applicable committees of the Board of Directors shall consult with our legal counsel.

Our company has entered into indemnification agreements with each of our directors and executive officers. These agreements require us to indemnify such individuals, to the fullest extent permitted by Nevada law, for certain liabilities to which they may become subject as a result of their affiliation with our company.

On July 16, 2013, we entered into a securities purchase agreement, or the Securities Purchase Agreement, with Quest Resources Group, LLC, a Delaware limited liability company, or Seller, pursuant to which we acquired all of the issued and outstanding membership interests of Quest held by Seller, comprising 50% of the membership interests of Quest, or the Quest Interests. Our wholly owned subsidiary, Earth911, has held the remaining 50% of the membership interests of Quest for several years. Concurrently with the execution of the Securities Purchase Agreement, we assigned the Quest Interests to Earth911 so that Earth911 now holds 100% of the issued and outstanding membership interests of Quest. The purchase price for the Quest Interests consisted of the following: (i) 12,000,000 shares of our common stock issued to Brian Dick, a 50% owner of Seller and Chief Executive Officer of Quest; (ii) 10,000,000 shares of our common stock issued to Jeff Forte, a 50% owner of Seller and President of Quest; (iii) a convertible secured promissory note in the principal amount of $11.0 million payable to Mr. Dick; and (iv) a convertible secured promissory note in the principal amount of $11.0 million payable to Mr. Forte. The convertible secured promissory notes issued to each of Messrs. Dick and Forte, or collectively, the Notes, were each secured by a first-priority security interest in a 25% membership interest held by Earth911 in Quest (comprising a total of 50% of the membership interests of Quest), or the Collateral, as set forth in security and membership interest pledge agreements, by and between Earth911 and each of Messrs. Dick and Forte, or collectively, the Security Agreements. The Securities Purchase Agreement provided that the Audit Committee of our Board of Directors had the sole authority and discretion to authorize payments due and owing under the Notes and to take any actions and make all decisions related to the Notes and the Security Agreements, and required that we (a) deposited in escrow the total interest for the following month from our initial cash receipts from any source, including, without limitation, receivables, loans, sale of assets, or sale of securities, and (b) maintained a reserve of $1.5 million under our line of credit at all times to be used to make interest payments on the Notes, as determined in the sole discretion of the Audit Committee of our Board of Directors. The Securities Purchase Agreement provides that Seller and Messrs. Dick and Forte may not engage or become financially interested in any Competitive Business within the Restricted Territory (each as defined in the Securities Purchase Agreement) for a period of five years. The Securities Purchase Agreement also provides restrictions with respect to customers of Quest and non-solicitation of employees of Quest for a period of five years. The Securities Purchase Agreement further provided that if there was an event of default on the Notes, Seller and Messrs. Dick and Forte may have competed with us and solicited customers, provided that they resigned from all positions held with us.  On September 24, 2014, we paid $11,000,000 to the holders of the Sellers Notes and such holders converted the remaining $11,000,000 of principal, plus accrued interest through September 24, 2014 of $101,260, into 5,550,630 shares of our common stock.

On July 16, 2013, in connection with our acquisition of Quest, we entered into a stockholders voting agreement with Messrs. Saltz and Melby, or the Class P Stockholders, and Messrs. Dick and Forte, or the Class D Stockholders, pursuant to which the Class P Stockholders and the Class D Stockholders agreed to vote all shares of our common stock owned by them or acquired by them in the future for a board consisting of six Class P Directors as designated by the Class P Stockholders or, in the absence of such designation, a majority of the Class P Directors, and three Class D Directors as designated by the Class D Stockholders, or in the absence of such designation, a majority of the Class D Directors. The initial Class P Directors were Messrs. Saltz, Melby, Golden, Miller, and Monheit and Ms. Wadecki. The initial Class D Directors were Messrs. Cheney, Dick, and Forte. The stockholders voting agreement will continue until the earlier of (i) five years from the date of the agreement, (ii) such time as either the Class P Stockholders or the Class D Stockholders own less than 10% of our outstanding common stock, or (iii) the mutual agreement of the parties. On March 15, 2016, Mr. Melby transferred to Mr. Saltz all of his rights to designate Class P Directors pursuant to the stockholders voting agreement.

On July 16, 2013, we entered into a consulting agreement, or the Consulting Agreement, with Mr. Forte in connection with the closing of the Quest acquisition providing that Mr. Forte would provide services to us as a special projects consultant on a part-time basis for a period of 12 months. The Consulting Agreement provided that Mr. Forte was entitled to receive compensation of $25,000 per annum. Mr. Forte was also eligible to participate in any group insurance, pension, retirement, vacation, expense reimbursement, and other plans, programs, and benefits approved by our Board of Directors and generally made available to our part-time employees. The Consulting Agreement also provided for (i) a non-competition period of 12 months after the termination of Mr. Forte’s engagement with us and (ii) non-solicitation of our employees and customers for a period of 24 months after the termination of Mr. Forte’s engagement with us.

PROPOSAL TWO

ADVISORY VOTE ON EXECUTIVE COMPENSATION (“SAY-ON-PAY”)

Background

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, enables our stockholders to vote to approve, on an advisory (non-binding) basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with the SEC’s rules.

Summary

We are asking our stockholders to provide advisory approval of the compensation of our named executive officers (which consist of our former principal executive officer, our former interim principal executive officer, our principal financial officer, and our two other executive officersofficer who werewas serving as an executive officersofficer on December 31, 2014)2015), as such compensation is disclosed in the “Executive Compensation” section of this proxy statement. Our executive compensation program is designed to enable us to attract, motivate, and retain highly qualified executives. This program provides long-term stock-based incentive compensation that focuses our executives’ efforts on building stockholder value by aligning their interests with those of our stockholders. The following is a summary of some of the key points of our executive compensation program. We urge our stockholders to review the “Executive Compensation” section of this proxy statement for more information.

Base Salaries. We target base salaries at levels required to attract, motivate, and retain highly qualified executives with base salaries generally set at levels below those of our peer companies, taking into account we are in the early stages of our corporate development.

Our long-term stock-based incentive compensation program is designed to align the interests of our management and the interests of our stockholders. We strongly believe in utilizing our common stock to tie executive rewards directly to our long-term success and increases in stockholder value. Grants of stock-based awards to our executive officers enable those executives to develop and maintain an ownership position in our common stock. Grants of stock-based awards are intended to result in limited rewards if the price of our common stock does not appreciate, but may provide substantial rewards to executives as our stockholders in general benefit from stock price appreciation. Grants of stock-based awards also are intended to align compensation with the price performance of our common stock. Historically, our stock-based compensation has been through the grant of stock options.

Board Recommendation

Our board believes that the information provided above and within the “Executive Compensation” section of this proxy statement demonstrates that our executive compensation program is designed appropriately and is working to ensure that management’s interests are aligned with our stockholders’ interests to support long-term value creation.

The following resolution is submitted for a stockholder vote at the meeting:

RESOLVED, that the stockholders of the Company approve, on an advisory basis, the compensation of the Company’s named executive officers, as disclosed in the “Executive Compensation” section of this proxy statement.

The annual say-on-pay vote is advisory, and therefore not binding on our company, our Compensation Committee, or our Board of Directors. Although non-binding, the vote will provide information to our Compensation Committee and our Board of Directors regarding investor sentiment about our executive compensation philosophy, policies, and practices, which our Compensation Committee and our Board of Directors will be able to consider when determining executive compensation for the years to come.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” ADOPTION OF THE RESOLUTION APPROVING THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AS DISCLOSED IN THE EXECUTIVE COMPENSATION SECTION OF THIS PROXY STATEMENT.

PROPOSAL THREE

PROPOSAL TO AUTHORIZE OUR BOARD OF DIRECTORS TO AMEND OUR ARTICLES

OF INCORPORATION TO EFFECT AN UP TO 1-FOR-10 REVERSE STOCK SPLIT

OF OUR COMMON STOCK

Our Board of Directors has considered, approved, and recommends to the stockholders for their approval, an amendment to our articles of incorporation to effect an up to 1-for-10 reverse stock split of our common stock, with the exact ratio to be determined by our Board of Directors in its discretion at any time prior to August 29, 2016. The reverse stock split would be effective upon the filing of articles of amendment to the company’s articles of incorporation with the Secretary of State of the state of Nevada.

Under the proposed amendment, the total number of authorized shares would remain the same, which means that a reverse stock split would result in an increased number of authorized but unissued shares of our common stock. The reverse stock split would be realized simultaneously and in the same ratio for all shares of common stock. All of our stockholders would be affected uniformly by the reverse stock split, which would have no effect on the proportionate holdings of any of our stockholders, except for possible changes due to the treatment of fractional shares resulting from the reverse stock split. In lieu of issuing fractional shares, we will round up in the event a stockholder would be entitled to receive less than one share of common stock. In addition, the reverse stock split would not affect any stockholder’s proportionate voting power (subject to the treatment of fractional shares), and all shares of common stock would remain fully paid and non-assessable.

A reverse stock split would be effected, if at all, only upon a determination by our Board of Directors that the reverse stock split is in the best interests of our company and our stockholders at that time. No further action on the part of our stockholders would be required to either implement or abandon the reverse stock split. If our Board of Directors does not implement the reverse stock split prior to August 29, 2016, then the authority granted to our Board of Directors to implement the reverse stock split will terminate. At any time prior to the effectiveness of the reverse stock split, our Board of Directors may abandon the reverse stock split if it determines in its sole discretion that this proposal is no longer in the best interests of our company and our stockholders.

Reasons for the Reverse Stock Split

A reverse stock split can help us to regain compliance with Nasdaq continued listing requirements.

On September 1, 2015, we received a notification from Nasdaq Listing Qualifications advising us that our common stock had not maintained a minimum closing bid price of $1.00 per share for 30 consecutive business days (the “Minimum Bid Price Requirement”) as required by Nasdaq Listing Rule 5555(a)(2). We had 180 calendar days, or until February 29, 2016 (the “Compliance Deadline”), to regain compliance with the Minimum Bid Price Requirement. To regain compliance with the Minimum Bid Price Requirement, the bid price of our common stock had to close at or above $1.00 per share for a minimum of 10 consecutive business days prior to the Compliance Deadline.

On March 1, 2016, we received a notification from Nasdaq Listing Qualifications advising us that we are eligible for an extension of 180 calendar days, or until August 29, 2016 (the “Extended Compliance Deadline”), to regain compliance with the Minimum Bid Price Requirement. We are required to meet the continued listing requirement for market value of publicly held shares and all other listing standards for The Nasdaq Capital Market, with the exception of the Mimimum Bid Price Requirement, and we have provided written notice of our intention to cure the deficiency prior to the Extended Compliance Deadline, by effecting a reverse stock split, if necessary. If it appears to Nasdaq that we will not be able to cure the deficiency, or if we are not otherwise eligible, our securities will be subject to delisting. At that time, we may appeal the delisting determination to a Hearings Panel.

Effecting a reverse stock split would help to raise the closing bid price of our common stock and to regain compliance with the Minimum Bid Price Requirement for continued listing on The Nasdaq Capital Market.

A reverse stock split can avoid certain adverse effects of low trading prices for our securities.

Our Board of Directors considered that as a matter of policy, many institutional investors are prohibited from purchasing stocks below certain minimum price levels. For the same reason, brokers may be reluctant to recommend lower-priced stocks to their clients, or may discourage their clients from purchasing such stocks. Other investors may be dissuaded from purchasing lower-priced stocks because the commissions, as a percentage of the total transaction, tend to be higher for such stocks. Our Board of Directors believes that, to the extent that the price per share of our common stock remains at a higher per share price as a result of a reverse stock split, some of these concerns may be ameliorated. The combination of lower transaction costs and increased interest from investors could also have the effect of increasing the liquidity of our common stock.

The reverse stock split is not intended to be a going private transaction.

Our Board of Directors does not intend for this transaction to be the first step in a series of plans or proposals of a “going private transaction” within the meaning of Rule 13e-3 of the Exchange Act.

Principal Effects of the Reverse Stock Split

General

A reverse stock split would affect all holders of our common stock uniformly and would not change the proportionate equity interests of such stockholders, nor would the respective voting rights and other rights of holders of our common stock be altered, except for possible changes due to the treatment of fractional shares resulting from a reverse stock split. The par value of our common stock would not change as a result of the reverse stock split, and would remain at $0.001 per share regardless of the ratio determined by the Board of Directors for the reverse stock split.

Stockholders should recognize that once a reverse split is effected, they will own a fewer number of shares than they currently own. While we expect that a reverse split would result in an increase in the per share price of our common stock, a reverse split may not increase the per share price of our common stock in proportion to the reduction in the number of shares of our common stock outstanding. It also may not result in a permanent increase in the per share price, which depends on many factors, including our performance, prospects, and other factors that may be unrelated to the number of shares outstanding. The history of similar reverse stock splits for companies in similar circumstances is varied.

Once a reverse stock split is effected and should the per share price of our common stock decline, the percentage decline as an absolute number and as a percentage of our overall market capitalization may be greater than would occur in the absence of a reverse stock split. Furthermore, the liquidity of our common stock could be adversely affected by the reduced number of shares that would be outstanding after a reverse stock split.

In addition, a reverse split would likely increase the number of stockholders who own “odd lots” (stockholdings in amounts of less than 100 shares). Stockholders who hold odd lots typically will experience an increase in the cost of selling their shares, as well as possible greater difficulty in effecting such sales. Any reduction in brokerage commissions resulting from a reverse stock split may be offset, in whole or in part, by increased brokerage commissions required to be paid by stockholders selling odd lots created by a reverse stock split.

Finally, the number of authorized but unissued and unreserved shares of our common stock relative to the number of issued and reserved shares of our common stock would be increased. This increased number of authorized but unissued and unreserved shares of our common stock could be issued by our Board of Directors without further stockholder approval, which could result in dilution to the holders of our common stock.

The increased proportion of unissued and unreserved authorized shares to issued shares could also, under certain circumstances, have an anti-takeover effect. For example, the issuance of a large block of common stock could dilute the ownership of a person seeking to effect a change in the composition of our Board of Directors or

contemplating a tender offer or other transaction. However, the reverse stock split has not been authorized in response to any effort of which we are aware to accumulate shares of common stock or obtain control of our company.

Effect of the Reverse Stock Split on Stock Options

We currently have outstanding stock options to purchase shares of our common stock. Under the terms of the outstanding stock options and notes, the reverse stock split would effect a reduction in the number of shares of common stock issuable upon exercise of the stock options in proportion to the exchange ratio of any reverse stock split and would effect a proportionate increase in the exercise price of the outstanding stock options. In connection with a reverse stock split, the number of shares of common stock issuable upon exercise or conversion of outstanding stock options would be rounded to the nearest whole share and no cash payment would be made in respect of such rounding.

Accounting Matters

The reverse stock split would not affect total stockholders’ equity on our balance sheet. As a result of the reverse stock split, the stated capital component attributable to our common stock would be reduced to an amount equal to up to one-tenth of its present amount and the additional paid-in capital component will be increased by the amount by which the stated capital component is reduced. The per share net loss and net book value per share of our common stock would be increased as a result of a reverse split because there would be fewer shares of our common stock outstanding.

Tax Consequences

Each stockholder is urged to consult with such stockholder’s tax advisor with respect to any potential tax consequences of a reverse stock split.

Procedure for Effecting the Reverse Stock Split and Filing the Articles of Amendment

We will file the articles of amendment with the Secretary of State of the state of Nevada. The reverse stock split will become effective as of 5:00 p.m. Eastern time on the date of filing, which time on such date will be referred to as the “effective time.” At the effective time, each lot of up to 10 shares of common stock issued and outstanding immediately prior to the effective time will, automatically and without any further action on the part of our stockholders, be combined into and become one share of common stock, subject to the treatment for fractional shares described above, and each certificate which, immediately prior to the effective time represented pre-reverse split shares, will be deemed cancelled and, for all corporate purposes, will be deemed to evidence ownership of post-reverse split shares. However, a stockholder will not be entitled to receive any dividends or distributions payable after the articles of amendment are effective until that stockholder surrenders and exchanges his or her certificates.

Our transfer agent will act as exchange agent for purposes of implementing the exchange of stock certificates. As soon as practicable after the effective time, a letter of transmittal will be sent to our stockholders of record as of the effective time for purposes of surrendering to the transfer agent certificates representing pre-reverse split shares in exchange for certificates representing post-reverse split shares in accordance with the procedures set forth in the letter of transmittal. No new certificates will be issued to a stockholder until such stockholder has surrendered such stockholder’s outstanding certificate(s), together with the properly completed and executed letter of transmittal, to the exchange agent. From and after the effective time, any certificates formerly representing pre-reverse split shares that are submitted for transfer, whether pursuant to a sale, other disposition, or otherwise, will be exchanged for certificates representing post-reverse split shares. STOCKHOLDERS SHOULD NOT DESTROY ANY STOCK CERTIFICATE(S) AND SHOULD NOT SUBMIT ANY CERTIFICATE(S) UNTIL REQUESTED TO DO SO.

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE AUTHORIZATION OF OUR BOARD OF DIRECTORS TO AMEND OUR ARTICLES OF INCORPORATION TO EFFECT AN UP TO 1-FOR-10 REVERSE STOCK SPLIT OF OUR COMMON STOCK.

PROPOSAL FOUR

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTANT

The firm of Semple, Marchal and Cooper, LLP, an independent registered public accounting firm, has audited the financial statements of our company and/or its predecessors for the fiscal years ended December 31, 2015, 2014, and 2013, the transition period ended December 31, 2012, and the fiscal years ended June 30, 2012 and 2011. Our Audit Committee has appointed Semple, Marchal and Cooper, LLP to audit the consolidated financial statements of our company for the fiscal year ending December 31, 20152016 and recommends that stockholders vote in favor of the ratification of such appointment. In the event of a negative vote on such ratification, the Audit Committee will reconsider its selection. We anticipate that representatives of Semple, Marchal and Cooper, LLP will be present at the meeting via telephone, will have the opportunity to make a statement if they desire, and will be available to respond to appropriate questions.

The Audit Committee has considered whether the provision of non-audit services by our independent registered public accountant is compatible with maintaining their independence.

Audit Fees and Audit-Related Fees

The aggregate fees billed to our company by Semple, Marchal and Cooper, LLP for the fiscal years ended December 31, 20142015 and 20132014 are as follows:

Audit Committee Pre-Approval Policies

The charter of our Audit Committee provides that the duties and responsibilities of our Audit Committee include the pre-approval of all audit, audit-related, tax, and other services permitted by law or applicable SEC regulations (including fee and cost ranges) to be performed by our independent registered public accountant. Any pre-approved services that will involve fees or costs exceeding pre-approved levels will also require specific pre-approval by the Audit Committee. Unless otherwise specified by the Audit Committee in pre-approving a service, the pre-approval will be effective for the 12-month period following pre-approval. The Audit Committee will not approve any non-audit services prohibited by applicable SEC regulations or any services in connection with a transaction initially recommended by the independent registered public accountant, the purpose of which may be tax avoidance and the tax treatment of which may not be supported by the Code and related regulations.

To the extent deemed appropriate, the Audit Committee may delegate pre-approval authority to the Chairman of the Audit Committee or any one or more other members of the Audit Committee provided that any

member of the Audit Committee who has exercised any such delegation must report any such pre-approval decision to the Audit Committee at its next scheduled meeting. The Audit Committee will not delegate the pre-approval of services to be performed by the independent registered public accountant to management.

Our Audit Committee requires that the independent registered public accountant, in conjunction with our Chief Financial Officer, be responsible for seeking pre-approval for providing services to us and that any request for pre-approval must inform the Audit Committee about each service to be provided and must provide detail as to the particular service to be provided.

All of the services provided by Semple, Marchal and Cooper, LLP described above under the caption “Audit-Related Fees” were approved by our Board of Directors or by our Audit Committee pursuant to our Audit Committee’s pre-approval policies.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE PROPOSAL TO RATIFY THE APPOINTMENT OF SEMPLE, MARCHAL AND COOPER, LLP AS THE INDEPENDENT REGISTERED PUBLIC ACCOUNTANT OF OUR COMPANY FOR THE FISCAL YEAR ENDING DECEMBER 31, 2015.2016.

DEADLINE FOR RECEIPT OF STOCKHOLDER PROPOSALS

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

If you and other stockholders of record with whom you share an address currently receive multiple copies of our proxy statement and annual report and would like to participate in our householding program, please contact Continental Stock Transfer & Trust Company by calling (212) 509-4000, or by writing to Continental Stock Transfer & Trust Company, 17 Battery Place, 8th8th Floor, New York, New York 10004. Alternatively, if you participate in householding and wish to revoke your consent and receive separate copies of our proxy statement and annual report, please contact Continental Stock Transfer & Trust Company as described above.

A number of brokerage firms have instituted householding. If you hold your shares in street name, please contact your bank, broker, or other holder of record to request information about householding.
