3.3.You May Vote in Person at the Meeting.You may deliver your completed proxy card in person. Additionally, we will pass out written ballots to registered stockholders who wish to vote in person at the meeting.

Beneficial Owners.

If you hold your shares in street name, follow the voting instruction card you receive from your bank, broker or other nominee. If you want to vote in person at the annual meeting, you must obtain a legal proxy from your bank, broker or nominee and present it at the annual meeting.

Can I change my vote?

Stockholders of Record.You may change your vote at any time before the proxy is exercised by voting in person at the annual meeting, giving written notice to Saia’s Secretary revoking your proxy, submitting a properly

signed proxy bearing a later date or voting again by telephone or on the internet (your latest telephone or internet vote is counted).

2

Beneficial Owners.If you hold your shares through a bank, broker or other nominee, you may change your vote by submitting new voting instructions following the instructions provided by your bank, broker or nominee.

What if I do not vote for some of the items listed on the proxy card or voting instruction card?

Stockholders of Record.If you indicate a choice with respect to any matter to be acted upon on your proxy card, the shares will be voted in accordance with your instructions. Proxy cards that are signed and returned, but do not contain voting instructions with respect to a proposal, will be voted in accordance with the recommendations of the Board with respect to that proposal.

Beneficial Owners.If you indicate a choice with respect to any matter to be acted upon on your voting instruction card, the shares will be voted in accordance with your instructions. If you do not indicate a choice with respect to a proposal or do not return your voting instruction card, the bank, broker or other nominee will determine if it has the discretionary authority to vote your shares. Regulations prohibit banks, brokers and other nominees from voting shares in elections of directors, approval ofwith respect to the Second Amended and Restated Saia, Inc. 20112018 Omnibus Incentive Plan or as to compensation of the Named Executive Officers, unless the beneficial owners indicate how the shares are to be voted. Therefore, unless you instruct your bank, broker or nominee on how to vote your shares with respect to the election of directors, approval of the Second Amended and Restated Saia, Inc. 20112018 Omnibus Incentive Plan andor the compensation of Saia’s Named Executive Officers, your bank, broker or nominee will be prohibited from voting on your behalf on any such matter for which your instructions are not provided.As such, it is critical that you cast your vote if you want it to count for the proposals regarding the aforementioned matters. Your bank, broker or nominee will, however, continue to have discretionary authority to vote uninstructed shares on the ratification of the appointment of the Company’s independent registered public accounting firm.

How many shares must be present to hold the meeting?

A quorum must be present at the annual meeting for any business to be conducted. The presence at the annual meeting, in person or by proxy, of the holders of a majority of the shares of Saia common stock outstanding on the record date will constitute a quorum. Abstentions and broker non-votes (which occur when a bank, broker or other nominee holding shares for a beneficial owner does not have discretionary voting authority with respect to a proposal and has not received instructions with respect to that proposal from the beneficial owner) will be treated as shares present for purposes of determining whether a quorum is present.

What if a quorum is not present at the meeting?

If a quorum is not present at the start of the meeting, the stockholders who are represented may adjourn the meeting until a quorum is present. The time and place of the adjourned meeting will be announced at the time the adjournment is taken, and so long as the adjournment is not for longer than 30 days, no other notice will be given.

How does the Board of Directors recommend I vote on the proposals?

Your Board recommends that you vote:

Will any other business be conducted at the meeting?

We know of no other business that will be presented at the meeting. If any other matter properly comes before the stockholders for a vote at the meeting, the proxy holders will vote your shares in accordance with their best judgment.

3

Who will count the votes?

Saia’s transfer agent, Computershare Trust Company, N.A., will tabulate and certify the votes. Douglas L. Col, the Company’s Treasurer and Assistant Secretary, will serve as the inspector of elections.

How many votes are required to elect the director nominees?

Because this is considered an uncontested election under the Company’s Bylaws, a nominee for director is elected to the Board if the votes cast for such nominee’s election exceed the votes cast against such nominee’s election. Abstentions will not affect the election of directors. In tabulating the voting results for the election of directors, only “FOR” and “AGAINST” votes are counted. If an incumbent director fails to receive a majority of the vote for re-election, the Nominating and Governance Committee of the Board will act on an expedited basis to determine whether to accept the director’s previously tendered irrevocable resignation and will submit such recommendation for prompt consideration by the Board. In considering whether to accept or reject the tendered resignation, the Nominating and Governance Committee and the Board will consider any factors they deem relevant. Any director who fails to receive a majority of the vote for re-election pursuant to this provision of the Corporate Governance Guidelines will not participate in the Nominating and Governance Committee recommendation or Board consideration regarding whether or not to accept the tendered resignation.

What happens if a nominee is unable to stand for election?

If a nominee is unable to stand for election, the Board of Directors may either reduce the number of directors to be elected or select a substitute nominee. If a substitute nominee is selected, the proxy holders will vote your shares for the substitute nominee unless you have withheld authority.

How many votes are required to approve the proposals other than the director nomination proposal?

The approval of the Second Amended and Restated Saia, Inc. 20112018 Omnibus Incentive Plan, the advisory approval of the compensation of Saia’s Named Executive Officers and the ratification of the appointment of KPMG LLP as Saia’s independent registered public accounting firm each require the affirmative vote of a majority of the shares present at the meeting in person or by proxy and entitled to vote.

What effect will abstentions and broker non-votes have on the proposals?

Shares voting “ABSTAIN” with respect to any nominee for director will be excluded entirely from the vote and will have no effect on the proposal. Shares voting “ABSTAIN” on the approval of the Second Amended and Restated Saia, Inc. 20112018 Omnibus Incentive Plan, the advisory vote on executive compensation, and the ratification of the appointment of the Company’s independent registered public accounting firm will be treated as shares present for quorum purposes and entitled to vote, so they will have the same practical effect as votes against the proposals. In tabulating the voting results for any particular proposal, shares that constitute broker non-votes are not considered entitled to vote on that proposal. Thus, broker non-votes will not affect the outcome of any matter being voted on at the meeting, assuming that a quorum is obtained.

When will the Company announce the voting results?

We will announce the preliminary voting results at the annual meeting. The Company will report the final results in a Current Report on Form 8-K filed with the Securities and Exchange Commission within four business days following the annual meeting.

Ward for election as Class III directors for three-year terms expiring at the annual meeting of stockholders to be held in 20192021 and until their successors are elected and qualified. Ms. Eisnor and Messrs. Holland, O’DellEvans, Trucksess and RockelWard currently serve as Class III directors.

Each nominee has consented to being named in this proxy statement and has agreed to serve if elected. If a nominee is unable to stand for election, the Board of Directors may either reduce the number of directors to be elected or select a substitute nominee. If a substitute nominee is selected, the proxy holders will vote your shares for the substitute nominee, unless you have withheld authority.

Because this is considered an uncontested election under the Company’s Bylaws, a nominee for director is elected to the Board if the votes cast for such nominee’s election exceed the votes cast against such nominee’s election. Abstentions will not affect the election of directors. In tabulating the voting results for the election of directors, only “FOR” and “AGAINST” votes are counted. If an incumbent director fails to receive a majority of the vote for re-election, the Nominating and Governance Committee of the Board will act on an expedited basis to determine whether to accept the director’s previously tendered irrevocable resignation and will submit such recommendation for prompt consideration by the Board. In considering whether to accept or reject the tendered resignation, the Nominating and Governance Committee and the Board will consider any factors they deem relevant. Any director who fails to receive a majority of the vote for re-election pursuant to this provision of the Corporate Governance Guidelines will not participate in the Nominating and Governance Committee recommendation or Board consideration regarding whether or not to accept the tendered resignation.

YOUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE ELECTION OF EACH OF THE THREEFOUR NOMINEES.

The following tables set forth certain information regarding each nominee for director and continuing director of the Company. The information presented includes information provided to the Company by each nominee and continuing director including such person’s name, age, principal occupation and business experience for at least the past five years, the names of other publicly-held companies of which such person currently serves as a director or has served as a director during the past five years and the year in which the nominee first became a director of Saia.

Evans, Linda J. French, John P. Gainor, Jr., John J. Holland, Randolph W. Melville, Björn E. Olsson, Douglas W. Rockel and Jeffrey C. Ward.

In addition to the information presented below regarding the specific experience, qualifications, attributes and skills of each nominee and director that led the Board of Directors to the conclusion that such person should serve as a director, the Board also believes that all of the nominees and continuing directors have a reputation for high personal and professional ethics, integrity, values and character. Each nominee and continuing director brings a strong and unique background and set of skills to the Board of Directors giving the Board as a whole competence and experience in a wide variety of areas, including corporate governance and board service, executive management, lawsales and regulation,marketing, the less-than-truckload (“LTL”) and transportation industry, accounting and finance, and risk assessment. They have demonstrated business acumen and an ability to exercise sound judgment, as well as a commitment of service to the Company and the Board. Each nominee and continuing director is committed to achieving, monitoring and improving on the Company’s business strategy.

The Board of Directors assesses diversity in its broadest sense and considers the backgrounds, experiences and viewpoints of its members and director candidates.  When identifying candidates for director, the Board endeavors to search for highly qualified women and individuals from minority groups to include in the pool from which directors are chosen.

CORPORATE GOVERNANCEG

THE BOARD, BOARD MEETINGS AND COMMITTEESOVERNANCE

The system of governance practices followed by the Company is memorialized in the Company’s Bylaws, in the charters of the three standing committees of the Board of Directors (the Audit Committee, the Compensation Committee and the Nominating and Governance Committee) and in the Company’s Corporate Governance Guidelines. The committee charters and Corporate Governance Guidelines are intended to provide the Board with the necessary authority and practices to review and evaluate the Company’s business and to make decisions independent of the influence of the Company’s management. The Corporate Governance Guidelines establish guidelines for the Board with respect to Board meetings, Board composition, selection and election of directors, director responsibility, director access to management and independent advisors and non-employee director compensation.

The committee charters and the Corporate Governance Guidelines are reviewed annually by the Board and updated as necessary to reflect evolving governance practices and changes in regulatory requirements. The Corporate Governance Guidelines and each of the Board’s committee charters are available free of charge on the Company’s website (www.saiacorp.com) under the investor relations section.

The Company has adopted a Code of Business Conduct and Ethics applicable to all directors, officers and employees, including its principal executive officer, principal financial officer and principal accounting officer. The Code of Business Conduct and Ethics is filed as Exhibit 14.1 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014, and incorporated by reference into the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015,2017, filed with the Securities and Exchange Commission.  The Code of Business Conduct and Ethics, the Corporate Governance Guidelines and each of the Board’s committee charters are available free of charge under the “Investor Relations – Governance” page of the Company’s website (www.saiacorp.com).

Board Leadership Structure

Saia’s Board structure provides for a Chief Executive Officer separate from the Chairman of the Board. The Board believes having a separate Chairman and Chief Executive Officer allows each to more fully focus on their applicable responsibilities. Further, maintaining separate roles allows the Chairman to oversee the Chief Executive Officer’s performance and remain more impartial when governing the Board. The Chief Executive Officer is responsible for settingimplementing the strategic direction forof the Company and managing the day-to-day operation and performance of the Company, while the Chairman provides guidance to the Chief Executive Officer, sets the agenda for Board meetings and presides over meetings of the full Board.

The Lead Independent Director is “independent” under all applicable rules of the NASDAQ Global Select Market and the Securities and Exchange Commission and is elected annually by the independent directors. For 2015,2017, the Lead Independent Director was Björn E. Olsson. The primary responsibilities of the Lead Independent Director are to:

In addition, the Lead Independent Director has the authority to call meetings of independent directors. If requested by major stockholders, the Lead Independent Director will make himself reasonably available for direct communication.

11

Meetings

The Board of Directors held five meetings in 2015.2017. Each director attended at least 75% of the meetings convened by the Board and the applicable committees during such director’s service on the Board during 2015.2017.

Executive sessions of non-employee directors and separate executive sessions of independent directors are held as part of each regularly scheduled meeting of the Board. The sessions of the independent directors are chaired by the Lead Independent Director.

Board Committees

The Board of Directors has an Audit Committee, a Compensation Committee and a Nominating and Governance Committee, each of which is comprised entirely of independent directors. Current Committee memberships are as follows:

Mr. Gainor joined the Board of Directors in February 2016 and will be considered for committee position(s) after the 2016 annual meeting.

Audit Committee

The Audit Committee has been established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the “Securities Exchange Act of 1934”). The Audit Committee held five meetings in 2015.2017. The functions of the Audit Committee are described in the Audit Committee charter and include, among others, the following:

Each member of the Audit Committee meets the independence and experience requirements for audit committee members as established by The NASDAQ Global Select Market. The Board of Directors has determined that Mr. Evans, Mr. Holland and Mr. Rockel are “audit committee financial experts,” as defined by applicable rules of the Securities and Exchange Commission.

Compensation Committee

The Compensation Committee held nineseven meetings in 2015.2017. The functions of the Compensation Committee are described in the Compensation Committee charter and include, among others, the following:

Each member of the Compensation Committee qualifies as (i) an independent director under applicable NASDAQ rules and Rule 10C-1 of the Securities Exchange Act of 1934; (ii) an “outside director” for purposes of Section 162(m) of the Internal Revenue Code of 1986 (the “Internal Revenue Code”), as amended; and (iii) a “non-employee director” for purposes of Rule 16b-3 of the Securities Exchange Act of 1934.

Compensation Consultant

The Compensation Committee has retained Mercer US, Inc. (“Mercer”) as its executive compensation consultant to provide information, analysis and recommendations regarding executive and director compensation. While it is necessary for the Committee’s consultant to interact with management to gather information, the Committee has adopted protocols governing if and when the consultant’s advice and recommendations can be shared with management. The Committee regularly meets with the Mercer consultant outside the presence of management to discuss executive compensation philosophy and specific levels of compensation and to ensure that Mercer receives from management the information required to perform its duties on a timely basis. The Compensation Committee formally evaluates the performance of Mercer on an annual basis and may terminate the services of Mercer at any time.

For 2017, the Company paid Mercer $93,472 for executive and director compensation services rendered to the Compensation Committee. Mercer is a wholly-owned subsidiary of Marsh & McLennan Companies, Inc. (“MMC”). For the past few years, including during 2017, the Company has used Marsh USA, Inc., an affiliate of MMC, to provide insurance brokerage services, based on a determination made by management in consideration of the expertise of Marsh USA, Inc. in providing insurance brokerage services for the transportation industry. The Company paid Marsh USA, Inc. $663,320 in fees in 2017 for such insurance brokerage services (this amount does not include insurance premiums that are paid through Marsh USA, Inc. to insurance carriers on behalf of Saia).

In connection with the Committee’s consideration of the independence of Mercer, the Committee confirmed with Mercer that:

In its evaluation of the relationship with Mercer, the Committee also reviewed the protocols used by the Committee in its dealings with Mercer which include:

Following this assessment of the relationship of Mercer and its affiliates with the Company, the Compensation Committee concluded that Mercer’s work for the Committee does not raise any conflict of interest and that Mercer qualified as independent.

Nominating and Governance Committee

The Nominating and Governance Committee held two meetings in 2015.2017. The functions of the Nominating and Governance Committee are described in the Nominating and Governance Committee charter and include, among others, the following:

Each member of the Nominating and Governance Committee meets the definition of an independent director under applicable NASDAQ rules.

Risk Oversight

The Board of Directors oversees an enterprise-wide approach to risk management, designed to support the achievement of Company objectives, improve long-term Company performance and create stockholder value. A fundamental part of risk management is not only understanding the risks the Company faces and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for the Company. The involvement of the full Board of Directors in setting the Company’s business strategy and objectives is integral to the Board’s assessment of the Company’s risk and also a determination ofin determining what constitutes an appropriate level of risk for the Company. The full Board of Directors conducts an annual risk assessment of the Company’s financial risk, legal/compliance risk and operational/strategic risk. The Board typically reviews at least one risk element in detail at each regular Board meeting and addresses individual risk issues throughout the year as necessary.

While the Board of Directors has the ultimate oversight responsibility for the risk management process, the Board delegates responsibility for certain aspects of risk management to its committees. In particular, the Audit Committee focuses on key business and financial risks and related controls and processes. Per its charter, the Audit Committee discusses with management the Company’s major financial reporting exposures concerning risk assessment and management and the steps management has taken to monitor and control such exposures. The Company’s Compensation Committee strives to create incentives that encourage a level of risk-taking behavior

consistent with the Company’s business strategy and objectives and helps ensure that the Company’s compensation policies and practices are not reasonably likely to have a material adverse effect on the Company. The Compensation Committee structures the Company’s executive compensation program to reduce the possibility that Saia’s executive officers, either individually or as a group, make excessively risky business decisions that could maximize short-term results at the expense of long-term value.

Finally, the Company’s Nominating and Governance Committee is responsible for overseeing the Company’s

13

major non-financial reporting enterprise risk assessment and management processes. The Chair of the Nominating and Governance Committee discusses with both the Audit Committee and the Compensation Committee the processes used in the oversight of the non-financial reporting enterprise risk assessment and management processes.

The Board believes its leadership structure enhances overall risk oversight. While the Board requires risk assessments from management, the combination of Board member experience, continuing education and independence of governance processes provide an effective basis for testing, overseeing and supplementing management assessments.assessments of risk.

ELECTION OF DIRECTORS

Election to the Company’s Board of Directors in a contested election is by a plurality of the votes cast at any meeting of stockholders having a quorum. An election will be considered contested if (i) the Secretary of the Company receives a notice that a stockholder has nominated a person for election to the Board of Directors in compliance with the advance notice requirements for stockholder nominees for director set forth in the Company’s Bylaws and (ii) such nomination has not been withdrawn by such stockholder on or before the 10th day before the Company first mails its notice of meeting for such meeting to the stockholders. If directors are to be elected by a plurality of the votes cast, stockholders are not permitted to vote against a nominee.

In an uncontested election, directors are elected by a majority of the votes cast “FOR” and “AGAINST” at any meeting of stockholders having a quorum. If an incumbent director fails to receive a majority of the vote for re-election in an uncontested election, the Nominating and Governance Committee will act on an expedited basis to determine whether to accept the director’s previously tendered irrevocable resignation and will submit such recommendation for prompt consideration by the Board. In considering whether to accept or reject the tendered resignation, the Nominating and Governance Committee and the Board will consider any factors they deem relevant. Any director who fails to receive a majority of the vote for re-election pursuant to this provision of the Corporate Governance Guidelines will not participate in the Nominating and Governance Committee recommendation or Board consideration regarding whether or not to accept the tendered resignation. The election of directors at the 20162018 annual meeting of the Company’s stockholders is an uncontested election.

The Board will nominate for election or re-election as director only candidates who agree to tender irrevocable resignations that will be effective upon (i) the failure to receive the required vote at the next annual meeting at which they will face re-election and (ii) Board acceptance of such resignation. The Board will fill director vacancies and new directorships only with candidates who agree to tender, promptly following their appointment to the Board, the same form of resignation tendered by other directors in accordance with the Corporate Governance Guidelines.

CONSIDERATION OF DIRECTOR NOMINEES

Director Qualifications and Selection

The Nominating and Governance Committee is responsible for recommending director candidates to the Board of Directors. The Nominating and Governance Committee will apply the criteria set forth in the Corporate Governance Guidelines when considering whether to recommend any candidate as a director nominee, including candidates recommended by stockholders. The Nominating and Governance Committee seeks nominees with a broad range of experience, professions, skills, geographic representation and backgrounds. The Nominating and

Governance Committee believes that the backgrounds and qualifications of the directors, considered as a group, should provide a significant composite mix of experience, knowledge and abilities that will allow the Board to fulfill its responsibilities.

The Board assesses diversity in its broadest sense and considers the backgrounds, experiences and viewpoints of its members and director candidates. When identifying candidates for director, the Board endeavors to search for highly qualified women and individuals from minority groups to include in the pool from which directors are chosen.

The Corporate Governance Guidelines include director qualification standards whichthat provide as follows:

While the selection of qualified directors is a complex, subjective process that requires consideration of many intangible factors, the Corporate Governance Guidelines provide that directors and candidates for director generally should, at a minimum, meet the following criteria:

Procedures for Recommendations and Nominations by Stockholders

Stockholder Recommendations

The Nominating and Governance Committee has adopted policies concerning the process for the consideration of director candidates recommended by stockholders. The Nominating and Governance Committee will consider director recommendations from stockholders. Any stockholder wishing to recommend a

candidate for consideration should send the following information to the Secretary of the Company, Saia, Inc., 11465 Johns Creek Parkway, Suite 400, Johns Creek, Georgia 30097:

The recommendation must be accompanied by the information concerning the candidate required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to the Securities Exchange Act of 1934 and rules adopted thereunder, generally providing for the disclosure of:

The recommendation must describe all relationships between the candidate and the recommending stockholder and any agreements or understandings between the recommending stockholder and the candidate regarding the recommendation. The nominating recommendation shall describe all relationships between the candidate and any of the Company’s competitors, customers, suppliers or other persons with special interests regarding the Company.

The recommending stockholder must furnish a statement supporting its view that the candidate possesses the minimum qualifications prescribed by the Nominating and Governance Committee for director nominees, and briefly describing the contributions that the nominee would be expected to make to the Board and to the governance of the Company. The recommending stockholder must state whether, in the view of the stockholder, the candidate, if elected, would represent all stockholders and not serve for the purpose of advancing or favoring any particular stockholder or other constituency of the Company.

The nominating recommendation must be accompanied by the consent of the candidate to be interviewed by the Nominating and Governance Committee, if the Committee chooses to do so in its discretion (and the recommending stockholder must furnish the candidate’s contact information for this purpose), and, if nominated and elected, to serve as a director of the Company.

If a recommendation is submitted by a group of two or more stockholders, the information regarding recommending stockholders must be submitted with respect to each stockholder in the group.

The Secretary of Saia will promptly forward such materials to the Nominating and Governance Committee Chair and the Chairman of the Board of Saia. The Secretary will also maintain copies of such materials for future reference by the Committee when filling Board positions.

If a vacancy arises or the Board decides to expand its membership, the Nominating and Governance Committee will seek recommendations of potential candidates from a variety of sources (including incumbent directors, stockholders and the Company’s management). At that time, the Nominating and Governance Committee also will consider potential candidates submitted by stockholders in accordance with the procedures described above. The Nominating and Governance Committee then evaluates each potential candidate’s educational background, employment history, outside commitments and other relevant factors to determine whether he or she is potentially qualified to serve on the Board. The Nominating and Governance Committee seeks to identify and recruit the best available candidates and it intends to evaluate qualified stockholder candidates on the same basis as those submitted by other sources.

After completing this process, the Nominating and Governance Committee will determine whether one or more candidates are sufficiently qualified to warrant further investigation. If the process yields one or more desirable candidates, the Nominating and Governance Committee will rank them by order of preference, depending on their respective qualifications and Saia’s needs. The Nominating and Governance Committee Chair, or another director designated by the Nominating and Governance Committee Chair, will then contact the desired candidate(s) to evaluate their potential interest and to set up interviews with the full Nominating and Governance Committee. All such interviews are held in person and include only the candidate and the Nominating and Governance Committee members. Based upon interview results, the candidate’s qualifications and appropriate background checks, the Nominating and Governance Committee then decides whether it will recommend the candidate’s nomination to the full Board.

The Board of Directors has adopted procedures for stockholders to send communications to the Board or individual directors of the Company as follows:

Stockholders seeking to communicate with the Board of Directors should submit their written comments to the Secretary of the Company, Saia, Inc., 11465 Johns Creek Parkway, Suite 400, Johns Creek, Georgia 30097.

Subject to the following, the Chairman of the Board and the Lead Independent Director will receive copies of all stockholder communications, including those addressed to individual directors, unless such communications address allegations of misconduct or mismanagement on the part of the Chairman or Lead Independent Director. In such event, the Secretary of the Company will first consult with and receive the approval of the Lead Independent Director or Chairman, as applicable, before disclosing or otherwise discussing the communication with the director subject to the allegation.

18

The Secretary will consider each communication to determine whether it should be forwarded promptly or compiled and sent with other communications and other Board materials in advance of the next scheduled Board meeting.

Stockholders also have an opportunity to communicate with the Board of Directors at the Company’s annual meeting of stockholders.

Executive Compensation Philosophy and Oversight

Compensation Committee

Saia’s executive compensation philosophyprogram is determinedadministered by the Compensation Committee, which is made up entirely of independent directors.  The Compensation Committee, with the assistance of Mercer US, Inc., as independent compensation consultant, annually reviews the Company’s compensation philosophy, the overall design of the compensation program and the design elements of each component of compensation. In making decisions about compensation for the Named Executive Officers as described in the compensation tables in this proxy statement, the Compensation Committee takes the following factors into consideration, among others, although none of these factors is determinative individually:

The Compensation Committee reviews and approves all elements of our executive compensation program, other than Mr. O’Dell’s base salary, which is approved by the Board, based on a formal assessment of his performance conducted by the Board and based on the recommendation of the Compensation Committee.  Mr. O’Dell makes recommendations to the Compensation Committee as to elements of compensation for his direct reports and provides performance reviews to assist the Compensation Committee in setting executive compensation.

Compensation Consultant

The Committee enters into a consulting agreement with the outside consultant on an annual basis. The Committee has retained Mercer US, Inc. (“Mercer”) as its executive compensation consultant to provide information, market analysis and recommendations regarding executive and director compensation. While it is necessary for the Committee’s consultant to interact with management to gather information, the Committee has adopted protocols governing if and when the consultant’s advice and recommendations can be shared with management. The Committee regularly meets with the Mercer consultant outside the presence of management to discuss executive compensation philosophy and specific levels of compensation and to ensure that Mercer receives from management the information required to perform its duties on a timely basis. The Committee formally evaluates the performance of Mercer on an annual basis and may terminate the services of Mercer at any time.

Executive Compensation Philosophy

The Compensation Committee believes the executive compensation program should link pay with performance and should attract, motivate, reward and facilitate the retention of the executive talent required to achieve corporate objectives and to create

value for the Company’s stockholders. To this end, Saia integrates several key compensation components that are designed to align rewards with the short- and long-term performance of the Company and of each executive. These components are:

Pay equity

To create stockholder value and motivate its employees, the Company is committed to internal and external pay equity. With respect to internal equity, the Compensation Committee monitors, on an annual basis,reviews each year the relationship between the compensation of the Chief Executive Officer to that of other Named Executive Officers and salaried employees generally.

The Company does not have a policy regarding the target ratio of total compensation of the Chief Executive Officer to that of the other Named Executive Officers or salaried personnel, but the Committee does review compensation levels to ensure that appropriate equity exists. During the past three years, the Chief Executive Officer’s total direct compensation (salary and short- and long-term incentive awards) has been approximately 2.5two times the total direct compensation of the next highest paid Named Executive Officer, which the Committee believes is an appropriate multiple. See also CEO Pay Ratio, elsewhere in this proxy statement.

To test external pay equity, the Committee annually reviews compensation data for similar positions at peer group companies, described below, in the transportation industry with revenuesrevenue levels comparable to Saia’s.

The peer group companies

The Committee has selectedgenerally uses the market 50th percentile or market median (using the peer group) as the targeted positioning for compensation of the Company’s executives.executives, but will adjust compensation above or below that level based on individual performance, tenure and, in some cases, for executive retention and succession planning purposes.

The peer group used in the review for 20152017 and 20162018 was:

Some of the peer group companies have substantial stock ownership by executives. If the ownership amounts were disclosed by the peer group company to have a material impact on executive compensation levels, the specific compensation element is excluded from the competitive data and associated analysis.
