James L. Wainscott

CHAIRMAN OF THE BOARD, PRESIDENT AND

CHIEF EXECUTIVE OFFICER

It is my pleasure to invite you to the 2014 Annual Meeting of Stockholders of AK Steel Holding Corporation. The meeting will be held at 1:30 p.m., Eastern Daylight Saving Time, on Thursday, May 29, 2014, at the Hilton Columbus at Easton, located at 3900 Chagrin Drive, Columbus, Ohio 43219. Registration will begin at 1:00 p.m.

Attendance at the Annual Meeting is limited to stockholders of record as of the close of business on March 31, 2014, or their duly appointed proxies, and to guests of Management. If you cannot attend the meeting in person, I strongly urge you to participate by voting your proxy in one of the methods explained in the Notice of 2014 Meeting of Stockholders that you received in the mail.

Please note that this year one of the proposals being voted on (Proposal No. 5 to increase the total number of authorized shares of common stock) requires the affirmative vote of a majority of all outstanding shares of the Company’s common stock for approval (not just a majority of the shares actually voted). Thus, although your vote is always important, it is particularly important this year with respect to Proposal No. 5. Absent a higher-than-normal percentage of stockholders voting, it is possible that a majority of shares actually voted could be in favor of Proposal No. 5, but it still might fail because it did not receive a “For” vote by a majority of all outstanding shares entitled to vote. In other words, if you fail to vote with respect to Proposal No. 5, you will effectively be voting “Against” it whether you intend to or not. The Board believes that passage of Proposal No. 5 is in the best interests of the Company and its stockholders in order to provide the Company with greater flexibility in considering and planning for potential future corporate needs.

Please read the enclosed Notice of Meeting and the accompanying Proxy Statement carefully. Your vote is important. In addition to Proposal No. 5 noted above, there are four other proposals included in the accompanying Proxy Statement. The Board of Directors recommends that you vote your shares FOR all of the proposals in the Proxy Statement, as follows:

1. FOR the election of each of the nominee Directors (Proposal No. 1).

2. FOR the ratification of the appointment of Ernst & Young LLP as independent registered public accounting firm (Proposal No. 2).

3. FOR the approval of Named Executive Officer compensation (Proposal No. 3).

4. FOR the approval of the amendment and restatement of the Company’s Stock Incentive Plan (Proposal No. 4).

5. FOR the approval of the proposed amendment to the Company’s Restated Certificate of Incorporation to increase the number of authorized shares of common stock (Proposal No. 5)

If you cannot attend in person, you may listen to the Annual Meeting via the Internet. To listen to the live webcast, log on at www.aksteel.com and select the link on the homepage for the webcast of the 2014 Annual Meeting of Stockholders. The webcast will begin at 1:30 p.m. and will remain on the Company’s website for one year. Please note, however, that you cannot record your vote on this website. In order to vote by proxy, you must use one of the methods explained in the Notice of 2014 Meeting of Stockholders that you received in the mail.

Your continuing interest in our company is greatly appreciated. I look forward to seeing you at the Annual Meeting.

Stockholder Proposals for the 2015 Annual Meeting and Nominations of Directors

Other Matters

What is a “proxy?”

A proxy is a person or entity authorized to act for another person. In this instance, the Board of Directors has appointed a Proxy Committee to vote the shares represented by proxy forms submitted by stockholders to the Company prior to the Annual Meeting. Giving the Proxy Committee your proxy means that you authorize the Proxy Committee to vote your shares on your behalf at the Annual Meeting as you specifically instruct on your proxy card with respect to each proposal, or if a matter that is not raised on the proxy card comes up for a vote at the Annual Meeting, in accordance with the Proxy Committee’s best judgment.

Whom am I appointing as my proxy?

The Proxy Committee consists of James L. Wainscott, David C. Horn and Roger K. Newport.

What is a Proxy Statement?

The document you are reading is a Proxy Statement. It is intended to provide our stockholders with information necessary to vote in an informed manner on matters to be presented at the Annual Meeting. It is sent in conjunction with a solicitation of your proxy.

Why is the Company soliciting my proxy?

The Board of Directors is soliciting your proxy to vote at the Annual Meeting because you are a “stockholder of record,” which means that you were shown on the Company’s records as the owner of common stock of the Company or you were the beneficial owner of shares held in street name at the close of business on March 31, 2014, the record date. All stockholders of record are entitled to vote at the meeting. It is important that as many stockholders as possible attend the meeting, either in person or by proxy, and vote on the issues to be decided at the Annual Meeting. The process of soliciting proxies is intended to increase the number of stockholders who vote on those issues.

Why did I receive more than one Proxy Statement or proxy card?

You may receive more than one Proxy Statement and proxy card if you hold AK Steel stock in different ways (e.g., joint tenancy, in trust, or in a custodial account) or in multiple accounts.

What is the difference between a “stockholder of record” and a beneficial owner of shares held in “street name?”

Stockholder of Record.    If your shares are registered directly in your name with the Company’s transfer agent, Computershare Investor Services, LLC (“Computershare”), you are considered the stockholder of record with respect to those shares.

How do I obtain voting instructions if my stock is held in “street name?”

If your stock is held in “street name,” you will receive a notice, typically entitled “Voting Instruction Form” or something similar, either electronically or by mail from the bank, broker or other institution holding your stock. This notice contains instructions regarding how to access the proxy materials and how to vote.

If I hold my stock in street name and fail to provide specific voting instructions to the bank, broker or other institution holding it on my behalf, will my stock still get voted?

Not on all matters. If you hold your shares in street name and want a vote to be cast on your behalf for all proposals described in this Proxy Statement, you must submit your specific voting instructions to the bank, broker or other institution holding the stock on your behalf in response to the notice you receive from it.

If I hold my stock in street name and do not provide specific voting instructions to the bank, broker or other institution holding it on my behalf, for which proposals will a vote not be cast on my behalf?

If you are a holder of shares in street name and you fail to provide specific voting instructions to the bank, broker or other institution holding the stock on your behalf, a vote will not be cast on your behalf with respect to the following proposals:

the election of Directors (Proposal No. 1);

the advisory vote on Named Executive Officer compensation (Proposal No. 3); and

the approval of the amendment and restatement of the Company’s Stock Incentive Plan (Proposal No. 4).

If I hold my stock in street name and do not provide specific voting instructions to the bank, broker or other institutions holding it on my behalf, for which proposals may a vote be cast on my behalf?

If you are a holder of shares in street name and you fail to provide specific voting instructions to the bank, broker or other institution holding the stock on your behalf, that entity may cast a vote on your behalf only with respect to the following proposals:

the ratification of the appointment of the independent registered public accounting firm (Proposal No. 2); and

the approval of the proposed amendment to the Company’s Restated Certificate of Incorporation to increase the number of authorized shares of common stock (Proposal No. 5).

What are “broker non-votes” and how are they counted for voting purposes?

“Broker non-votes” occur when a broker (or a bank or other institution holding someone’s shares) returns a proxy, but does not vote the shares represented by that proxy on a particular proposal, usually because the beneficial owners of those shares have not provided direction to the holder on how to vote them and the holder does not have discretionary voting power with respect to the proposal. Broker non-votes do not count

for voting purposes, but are considered “present” at the meeting and are counted to determine whether there is a quorum present at the meeting.

What documentation must I provide to be admitted to the Annual Meeting?

If your shares are registered in your name, you will need to present personal photo identification. If your shares are not registered in your name (if, for instance, your shares are held in street name for you by your broker, bank or other institution), you must present (1) personal photo identification, and (2) proof of stock ownership. We will accept as proof of stock ownership either a copy of your account statement or a letter from your broker, bank or other institution, as long as such statement or letter reflects the number of shares of common stock you owned as of March 31, 2014.

What documentation must I provide to vote in person at the Annual Meeting?

Upon admission, if you are a stockholder of record, you may vote all shares registered in your name in person at the Annual Meeting. If you are not a stockholder of record as to any of your shares (i.e., instead of being registered in your name, all or a portion of your shares are registered in a street name and held by your broker, bank or other institution for your benefit), you must obtain and bring with you to the meeting a “legal proxy” from the broker, bank or other institution in whose name any of your shares are held in order to vote those shares in-person at the meeting. You should contact the bank, broker or other institution that holds those shares for specific information on how to obtain a legal proxy in order to vote them at the meeting.

Is there any way for me to vote other than in person or by proxy at the Annual Meeting?

Yes. If you are a stockholder of record, you may vote over the telephone or via the Internet. The proxy card from the Company you received in the mail contains instructions for voting by these methods. If you hold your shares in street name, you must follow the instructions contained in the voting instruction card provided to you by the broker, bank or other institution holding your shares on your behalf.

Do I vote only once regardless of how many shares I own? If not, how many votes do I get to cast?

You are entitled to one vote for each share of common stock in the Company which you held as of the close of business on March 31, 2014.

What is a quorum and why is it important?

In the context of the Annual Meeting, a quorum is the presence at the meeting, either in person or by proxy, of stockholders holding the minimum number of shares of the Company’s stock necessary to make the proceedings of that meeting valid under the Company’s By-laws and applicable law.

What are my choices when voting on a particular proposal?

You may vote “FOR”, “AGAINST” or “ABSTAIN” with respect to every proposal.

How many votes are needed for the proposals to pass?

Election of Directors (Proposal No. 1).    The affirmative vote of a majority of the votes cast at the Annual Meeting in person or by proxy is required for election as a Director. The “affirmative vote of a majority of the votes cast” means that the number of votes cast “FOR” a Director Nominee’s election exceeds the

number of votes cast “AGAINST” such Director Nominee’s election. Abstentions and broker non-votes are not counted as votes in this context.

What does it mean to “ABSTAIN” from voting and what impact does that have?

If you indicate on your proxy card that you wish to “ABSTAIN” from voting with respect to a particular proposal, your shares will not be voted with respect to that proposal. Your shares, however, will be considered “present” and “entitled to vote” at the meeting and will be counted to determine whether there is a quorum present at the Annual Meeting. Beyond being counted for purposes of establishing a quorum, the practical effect of voting to “ABSTAIN” may vary depending upon the proposal for which you submit it. With respect to Proposals No. 1, No. 2, No. 3 and No. 4, voting to “ABSTAIN” will have no practical effect because the outcome of the vote on each proposal will be based upon the number of votes cast and votes to “ABSTAIN” are not counted as votes cast. With respect to Proposal No. 2 (ratification of the appointment of the independent registered public accounting firm) and Proposal No. 3 (approval of Named Executive Officer compensation), the vote is advisory in nature and, to the extent that the Board considers and gives weight to the voting results when considering future action on the subject of the proposal, a vote to “ABSTAIN” provides no input to the Board with respect to your preference on that subject. With respect to Proposal No. 5, voting to “ABSTAIN” has a different effect because the affirmative vote of a majority of the outstanding shares of common stock of the Company is required for approval of this proposal. Therefore, a vote to “ABSTAIN” on Proposal No. 5 effectively counts as a vote “AGAINST” the proposal.

Who will count the votes?

The votes will be counted by an inspector of election appointed by the Board. The Board has appointed Jeanine Simon of Computershare as the inspector of election and David Dietrich, also of Computershare, as an alternate inspector of election in the event Ms. Simon is unable to serve.

What happens if I return my proxy card but do not mark how I want my votes to be cast?

If you timely return a signed and dated proxy card, but do not mark how your shares are to be voted, those shares will be voted by the Proxy Committee as recommended by the Board of Directors.

How does the Board of Directors recommend that I vote?

The Board of Directors recommends that you vote your shares:

FOR the election of each of the nominee Directors (Proposal No. 1).

FOR the ratification of the appointment of Ernst & Young LLP as independent registered public accounting firm (Proposal No. 2).

FOR the approval of Named Executive Officer compensation (Proposal No. 3).

FOR the approval of the amendment and restatement of the Company’s Stock Incentive Plan (Proposal No. 4).

FOR the approval of the proposed amendment to the Company’s Restated Certificate of Incorporation to increase the number of authorized shares of common stock (Proposal No. 5).

personal qualities and characteristics, such as judgment, integrity, reputation in the business community and record of public service;

business and/or professional expertise, experience and accomplishments;

ability and willingness to devote sufficient time to the affairs of the Board and of the Company;

diversity of viewpoints, backgrounds and experience they will bring to the Board; and

the needs of the Company at the time of nomination to the Board and the fit of a particular individual’s skills and personality with those of other Directors in building a Board that is effective and responsive to the needs of the Company.

Mr. James L. Wainscott, the Company’s Chairman, President and Chief Executive Officer, is not included in this table because he is an employee of the Company and thus receives no compensation for his service as a Director and Chairman of the Board of Directors. Mr. Wainscott’s compensation from the Company for his service as an employee and Executive Officer is reported in the Summary Compensation Table beginning at page 62.

Mr. Abdoo elected to take an additional portion of his compensation in the form of RSUs during 2013, pursuant to the terms of the Company’s Stock Incentive Plan. This had the effect of reducing his cash compensation and increasing the value of his RSU awards in the table above.

The amounts in this column reflect the aggregate grant date fair value of RSUs granted in 2013, computed in accordance with ASC Topic 718, Compensation—Stock Compensation (“ASC Topic 718”). The amounts in this column also include accrued RSU dividend equivalents awarded to each Director in 2013. The average of the high and low selling price of the Company’s common stock on the date the fee is to be paid is used to calculate the number of RSUs to be issued. The actual number of RSUs granted each quarter is calculated by dividing the quarterly annualized amount (e.g., $22,500) by the average of the high and low sales price of the Company’s common stock on the grant date. For 2013, Mr. Abdoo, Mr. Brinzo, Mr. Cuneo, Dr. Hill and Mr. Wright elected to defer settlement of their RSUs until six months following the date they complete their service on the Board. As of December 31, 2013, non-employee Directors had the following aggregate number of RSUs outstanding (rounded to the nearest whole number): Mr. Abdoo, 135,008; Mr. Brinzo, 54,213; Mr. Cuneo, 48,434; Mr. Essig, 12,784; Mr. Gerber, 22,856; Dr. Hill, 93,188; Mr. Jenkins, 22,856; Mr. Michael, 22,856; Mrs. Peterson, 22,856; Dr. Thomson, 28,635; and Mr. Wright, 12,784.

No stock options were granted to Directors in 2013. As of December 31, 2013, non-employee Directors had the following aggregate number of options outstanding: Mr. Abdoo, 10,000; Mr. Brinzo, 10,000; Mr. Cuneo, 10,000; Mr. Gerber, 10,000; Mr. Jenkins, 10,000; Mr. Michael, 10,000; Mrs. Peterson, 10,000; and Dr. Thomson, 10,000.

The amounts in this column constitute matching charitable gift donations made by the AK Steel Foundation pursuant to a matching gift program. Under this program, employees and Directors of the Company are eligible for matching contributions by the Foundation of up to $5,000 per person per calendar year to qualifying charitable institutions. In certain instances, because of timing issues related to when a contribution is made by a participant in the program and when the participant submits the related matching gift form to the Company, a participant could have matching contributions from the Foundation totaling up to $10,000 paid in a single year relating to contributions by the participant spanning two calendar years.

Messrs. Essig and Wright were elected to the Board effective November 1, 2013, so their total compensation for 2013 is less than the other Directors. Upon their election, Messrs. Essig and Wright each received a grant of 10,044 RSUs.

A significant portion of the effective equity ownership in the Company by Directors is in the form of RSUs that do not satisfy the definition of “shares beneficially owned” for purposes of this table and therefore are not included in this table. An RSU is a grant valued in terms of stock, but no actual shares of stock are issued at the time of the grant. Only those RSUs which may be settled in shares of the Company’s stock on or before March 28, 2014 meet the definition of “shares beneficially owned”. None of the RSUs owned by the Directors will be settled on or before March 28, 2014 and thus none are included in this table. Directors had the following aggregate number of RSUs outstanding (rounded to the nearest whole number) as of March 28, 2014: Mr. Abdoo, 135,008; Mr. Brinzo, 54,213; Mr. Cuneo, 48,434; Mr. Essig, 12,784; Mr. Gerber, 22,856; Dr. Hill, 93,188; Mr. Jenkins, 22,856; Mr. Michael, 22,856; Mrs. Peterson, 22,856; Dr. Thomson, 28,635; and Mr. Wright, 12,784.

An asterisk indicates ownership of less than 1%.

Mr. Barlow left the Company effective July 18, 2013. The number of shares included in the table as beneficially owned by Mr. Barlow is as of the effective date of his resignation.

Mr. Ferrara retired from the Company effective August 31, 2013. The number of shares included in the table as beneficially owned by Mr. Ferrara is as of the effective date of his retirement.

Mr. Kaloski retired from the Company effective January 31, 2014. The number of shares included in the table as beneficially owned by Mr. Kaloski is as of the effective date of his retirement.

Introduction and Executive Summary of Pay-for-Performance Components and other Key Elements of the Executive Compensation Program

There were no payouts under the quality or financial performance components of the Company’s annual incentive plan;

There were no payouts under the Company’s long-term performance plan;

There were no payouts with respect to performance shares under the Company’s stock incentive plan; and,

There were no performance-based matches under the Company’s 401k plan.

For purposes of this Compensation Discussion and Analysis, the term “Named Executive Officers” or “NEOs,” when capitalized, refers to the following in reference to 2013 (with their titles as of December 31, 2013, unless otherwise noted):

James L. Wainscott — Chairman of the Board of Directors, President and Chief Executive Officer

David C. Horn — Executive Vice President, General Counsel and Secretary

John F. Kaloski — Executive Vice President and Operating Officer

Roger K. Newport — Vice President, Finance and Chief Financial Officer

Keith J. Howell — Vice President, Operations

Albert E. Ferrara, Jr. — (Retired) Senior Vice President, Corporate Strategy and Investor Relations

Gary T. Barlow – (Former) Vice President, Sales and Customer Service

base salary;

annual performance-based awards under the Company’s Management Incentive Plan (the “Annual Incentive Plan”);

long-term performance-based awards under the Company’s Long-Term Performance Plan (the “Long-Term Plan”);

awards of stock options, restricted stock and performance shares under the Company’s Stock Incentive Plan (the “Stock Plan”); and

certain employee benefits, perquisites and post-employment benefits.

Annual say-on-pay shareholder vote

A shareholder outreach program through which the chair of the Committee offers to speak directly with the Company’s largest shareholders with respect to their views on the Company’s executive compensation program

The Committee’s engagement of its own independent compensation consultant

The use of peer group and other comparative survey data provided by an independent compensation consultant in determining executive compensation

The establishment annually of a focus list of items for the CEO and an annual evaluation of the CEO’s and the Company’s performance that is factored into the annual determination of the CEO’s compensation package

A policy against re-pricing or replacing underwater options

An executive compensation clawback policy applied to performance-based compensation

Stockholder approval of certain severance agreements with senior executives

Executive Officer stock ownership guidelines

A policy prohibiting employees, including Executive Officers, from engaging in insider trading or hedging transactions, holding Company securities in margin accounts and the pledging of Company securities

No tax gross-ups or “single triggers” in the change of control agreements with its Executive Officers

Locking the Company’s Executive Minimum and Supplemental Retirement Plan, or “SERP”, to existing participants and replacing it for future officers with a new retirement plan

The only item referenced in the Summary Compensation Table not included in the charts on this and the next page is the change in pension value for each NEO. That value is excluded because it is not a component of compensation awarded annually by the Committee to the NEOs. Rather, it is a mathematical calculation of the actuarial change in value of the NEO’s pension that is attributable to factors outside the control of the Committee and the NEOs, such as a change in the discount rate used to present value the pension benefits or a change in the interest component of the value as a result of the NEO’s change in age relative to the NEO’s assumed retirement date. The change in value also is not a fair reflection of the NEO’s total compensation. That is illustrated by the difference in the change-in-value numbers for Mr. Wainscott for 2013 compared to 2012. In 2012, the calculated value of his pension increased by approximately $3.6 million. In 2013, it decreased by approximately $0.85 million. The difference is attributable almost entirely to changes in the discount rate used to determine Mr. Wainscott’s future pension value and to re-calculate it to its present value. For each year reported, the value is simply an actuarial calculation. In neither year did Mr. Wainscott realize any cash benefit (or detriment) attributable to the reported change in value.

Full Grant Date Fair Value of Award at time of grant — from Grants of Plan-Based Awards Table at page 60 of AK Steel Proxy Statement for 2012 Annual Meeting of Stockholders filed on April 9, 2012.

The performance share grants awarded in January 2011 expired in December 2013 with no shares of common stock being issued with respect to those grants. See below at page 40.

A substantial portion of the compensation granted by the Committee to the CEO and reported in the Summary Compensation Table at page 62 represented an incentive for future performance at the time it was awarded, not actual cash compensation.

Much of this incentive pay was never actually received for the years reported in the Summary Compensation Table and may not be received for many years in the future, if ever.

If and when this incentive pay is realized, the amount realized may differ significantly from the amounts shown in the Summary Compensation Table, depending on how the Company actually performs.

Actual base pay;

Incentive payouts and discretionary bonuses, if any, actually paid;

All other compensation actually paid; and

The fair value of all equity grants made, measured at the end of the most recently completed fiscal year. The fair value of stock options was determined using the Black-Scholes model based on year-end assumptions and the maximum remaining life of the options. The fair value of restricted stock and performance shares was determined using the average of the high and the low stock price on the last day of the fiscal year and assumes all vesting considerations were met.
