PROXY STATEMENT

---

GENERAL INFORMATION

        This Proxy Statement is being furnished in connection with the solicitation by the Board of Directors (the "Board of Directors" or the "Board") of Carlisle Companies Incorporated ("the Company") of proxies to be voted at the 2019 Annual Meeting of Stockholders (the "Annual Meeting"). The Annual Meeting will be held at 8:00 a.m., Eastern Time, on Wednesday, May 8, 2019 at the offices of Carlisle Interconnect Technologies, Inc. located at 100 Tensolite Drive, St. Augustine, Florida 32092.

        In accordance with the Securities and Exchange Commission rules and regulations (the "SEC rules"), instead of mailing a printed copy of the proxy materials to each stockholder of record, the Company is furnishing proxy materials to its stockholders via the Internet. You will not receive a printed copy of the proxy materials unless you request a copy. Instead, the Notice of Internet Availability of Proxy Materials instructs you how to access and review the proxy materials over the Internet. If you would like to receive a printed copy of the proxy materials, you should follow the instructions for requesting a copy included in the notice.

        The Notice of Internet Availability of Proxy Materials, or a printed copy of the proxy materials (including this Proxy Statement and form of proxy), as applicable, was sent to stockholders beginning March 26, 2019.

        The proxy is solicited by the Board of Directors of the Company. The cost of proxy solicitation will be borne by the Company. In addition to the solicitation of proxies by mail and the Internet, officers and regular employees of the Company may devote part of their time to solicitation by correspondence sent via e-mail, facsimile and telephone or personal calls. Arrangements may also be made with brokerage houses and other custodians, nominees and fiduciaries for the forwarding of solicitation materials to beneficial owners and for the reimbursement of their out-of-pocket and clerical expenses incurred in connection therewith. Proxies may be revoked at any time prior to the taking of the vote at the Annual Meeting. See "Voting by Proxy and Confirmation of Beneficial Ownership" beginning on page 54.

        The mailing address of the Company's principal executive offices is Carlisle Companies Incorporated, 16430 North Scottsdale Road, Suite 400, Scottsdale, Arizona 85254. Upon written request mailed to the attention of the Secretary of the Company, at the Company's principal executive offices, the Company will provide without charge a copy of its Annual Report on Form 10-K for the fiscal year ended December 31, 2018 filed with the Securities and Exchange Commission (the "SEC").

Shares Entitled to Vote; Quorum

        The record date for the Annual Meeting is March 13, 2019. Only holders of record of the Company's common stock ("Shares" or "Common Shares") as of the close of business on that date will be entitled to vote at the Annual Meeting. As of the record date, 57,198,932 Shares were outstanding. The presence, in person or by proxy, of the holders of a majority of the votes entitled to be cast is necessary to constitute a quorum for the transaction of business at the Annual Meeting.

Voting Rights and Procedures

        The Company's Restated Certificate of Incorporation provides that each person who received Shares pursuant to the Agreement of Merger, dated March 7, 1986, which was approved by the stockholders of Carlisle Corporation and became effective on May 30, 1986, is entitled to five votes per Share. Persons acquiring Shares after May 30, 1986 (the effective date of the merger) are entitled to one vote per Share until the Shares have been beneficially owned (as defined in the Restated

1

---

Table of Contents

Certificate of Incorporation) for a continuous period of four years. Following continuous ownership for a period of four years, the Shares are entitled to five votes per Share. The actual voting power of each holder of Shares will be based on stockholder records at the time of the Annual Meeting. See "Voting by Proxy and Confirmation of Beneficial Ownership" beginning on page 54. In addition, holders of Shares issued from the treasury, other than in connection with the exercise of stock options, before the close of business on March 13, 2019 (the record date for determining stockholders entitled to vote at the Annual Meeting) will be entitled to five votes per Share unless the Board of Directors determines otherwise at the time of authorizing such issuance.

Voting Methods

        If your Shares are registered directly in your name with the Company's transfer agent, Computershare Investor Services, LLC, you are considered the registered holder of those Shares. As the registered stockholder, you can ensure your Shares are voted at the Annual Meeting by submitting your instructions (i) via the Internet, (ii) by telephone (only if you received or request a proxy card) by calling the phone number on the proxy card, (iii) by mail (only if you received or request a proxy card) by completing, signing, dating and promptly returning the proxy card in the postage-paid envelope provided or (iv) by attending the Annual Meeting and voting your Shares in person at the meeting. Internet and telephone voting for registered stockholders will be available 24 hours a day, up until 11:59 p.m., Eastern Time, on May 7, 2019. You may obtain directions to the Annual Meeting in order to vote in person by calling the Company's principal executive offices at (480) 781-5000.

        Most Company stockholders hold their Shares through a bank, broker or other nominee, rather than directly in their name. In that case, you are considered the beneficial owner of Shares held in street name. As the beneficial owner, you are entitled to direct the voting of your Shares by your intermediary. Brokers, banks and other nominees typically offer telephonic or electronic means by which the beneficial owners of Shares held by them can submit voting instructions, in addition to the traditional mailed voting instruction forms. If you own your Shares indirectly through a bank, broker or other nominee, please follow the instructions you receive from the stockholder of record to vote your Shares. As the beneficial owner, if you wish to vote at the Annual Meeting, you will need to bring to the meeting a legal proxy from your bank, broker or other nominee authorizing you to vote those Shares.

        If you participate in the Carlisle, LLC Employee Incentive Savings Plan (the "401(k) Plan") and own Shares through your 401(k) Plan account, Wells Fargo Bank, N.A. ("Wells Fargo"), the trustee of the 401(k) Plan, will vote your 401(k) Plan Shares in accordance with the instructions you provide by voting via the Internet, by telephone or on the voting instruction form. If Wells Fargo does not receive voting instructions from you by 11:59 p.m., Eastern Time, on May 7, 2019, Wells Fargo will vote your 401(k) Plan Shares as directed by the Carlisle Pension and Insurance Committee, the 401(k) Plan administrator, in its discretion.

Voting Requirement to Approve Each of the Proposals

        The following sets forth the voting requirement to approve each of the proposals:

        Proposal 1, Election of Directors.    Directors shall be elected by the affirmative vote of a majority of the votes cast (meaning that the number of votes cast "for" a nominee must exceed the number of votes cast "against" such nominee). If any incumbent director who is a nominee for reelection receives a greater number of votes "against" his or her election than votes "for" such election in an uncontested election of directors, the Company's Amended and Restated Bylaws provide that the director must promptly tender his or her offer of resignation to the Board for consideration. See "Proposal 1: Election of Directors" for a more detailed description of the Company's director resignation policy.

Table of Contents

        Proposal 2, Ratification of the Appointment of Independent Registered Public Accounting Firm.    Ratification of the appointment of Deloitte & Touche LLP as the Company's independent registered public accounting firm for fiscal 2019 requires the affirmative vote of a majority of the total votes of all Shares present in person or represented by proxy and entitled to vote on the proposal at the Annual Meeting (meaning that of the total votes of all Shares represented at the Annual Meeting and entitled to vote, a majority of them must be voted "for" the proposal for it to be approved).

        Proposal 3, Advisory Vote to Approve Named Executive Officer Compensation.    Advisory approval of the Company's named executive officer compensation in fiscal 2018 requires the affirmative vote of a majority of the total votes of all Shares present in person or represented by proxy and entitled to vote on the proposal at the Annual Meeting (meaning that of the total votes of all Shares represented at the Annual Meeting and entitled to vote, a majority of them must be voted "for" the proposal for it to be approved).

        Other Items.    Approval of any other matters requires the affirmative vote of a majority of the total votes of all Shares present in person or represented by proxy and entitled to vote on the item at the Annual Meeting (meaning that of the total votes of all Shares represented at the Annual Meeting and entitled to vote, a majority of them must be voted "for" the item for it to be approved).

Effect of Abstentions and Broker Non-Votes

        Abstentions and broker non-votes are counted as present or represented for purposes of determining the presence or absence of a quorum for the Annual Meeting. A broker non-vote occurs when a nominee holding Shares in street name for a beneficial owner votes on one proposal but does not vote on another proposal because, with respect to such other proposal, the nominee does not have discretionary voting power and has not received voting instructions from the beneficial owner.

        Under the New York Stock Exchange rules (the "NYSE rules"), Proposal 2, the ratification of the appointment of Deloitte & Touche LLP as the Company's independent registered public accounting firm for fiscal 2019, is considered a "routine" matter, which means that brokerage firms may vote in their discretion on this proposal on behalf of clients who have not furnished voting instructions. However, Proposals 1 and 3, the election of directors and the advisory vote to approve the Company's named executive officer compensation in fiscal 2018, respectively, are "non-routine" matters under the NYSE rules, which means that brokerage firms that have not received voting instructions from their clients on these matters may not vote on these proposals.

        With respect to Proposal 1, the election of directors, you may vote "for" or "against" each of the nominees for the Board, or you may "abstain" from voting for one or more nominees. Abstentions and broker non-votes are not considered votes cast for the foregoing purpose and will therefore have no effect on the election of director nominees.

        With respect to Proposals 2 and 3, the ratification of the appointment of Deloitte & Touche LLP as the Company's independent registered public accounting firm for fiscal 2019 and the advisory vote to approve the Company's named executive officer compensation in fiscal 2018, respectively, you may vote "for" or "against" these proposals, or you may "abstain" from voting on these proposals. An abstention will be counted as a vote present or represented and entitled to vote on these proposals and will have the same effect as a vote "against" these proposals, and a broker non-vote will not be considered entitled to vote on these proposals and will therefore have no effect on their outcome. As discussed above, because Proposal 2, the ratification of the appointment of Deloitte & Touche LLP as the Company's independent registered public accounting firm for fiscal 2019, is considered a "routine" matter, we do not expect any broker non-votes with respect to this proposal.

SECURITY OWNERSHIP

A.    Certain Beneficial Owners

        The table below provides information about the beneficial ownership of Common Shares as of December 31, 2018 by each person known by the Company to beneficially own more than 5% of the outstanding Common Shares as of such date. As defined in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), "beneficial ownership" means essentially that a person has or shares voting or investment power over shares. It does not necessarily mean that the person enjoys any economic benefit from those shares. The ownership percentages are based on 58,126,596 Common Shares outstanding as of December 31, 2018.

PROPOSAL 1:
ELECTION OF DIRECTORS

        The number of directors is currently fixed at 10. The Company's Restated Certificate of Incorporation provides for a classified Board of Directors under which the Board is divided into three classes of directors, with each class as nearly equal in number as possible. Four directors are to be elected at the Annual Meeting. If elected, each nominee will serve for a three-year term expiring at the 2022 Annual Meeting of Stockholders or until his successor is duly elected and qualified. All of the nominees are currently serving as directors and have agreed to be named in this Proxy Statement and to serve if elected.

        Although the Company knows of no reason why any of the nominees would not be able to serve, if any nominee is unavailable for election, the proxy holders intend to vote your Shares for any substitute nominee proposed by the Board.

        Under the Company's Statement of Corporate Governance Guidelines and Principles, a director is required to submit his or her resignation at the annual meeting of stockholders following the earlier of the date when he or she reaches age 72 or has completed 18 consecutive years of service on the Board. Mr. Roberts will attain age 72 in 2020 and is therefore not expected to serve the full three-year term for which he is nominated for election at the Annual Meeting.

        The Company's Amended and Restated Bylaws provide for a majority vote standard in uncontested director elections, which means each director nominee must receive a majority of the votes cast with respect to that nominee at the Annual Meeting. For this purpose, a "majority of the votes cast" means that the number of votes cast "for" a nominee must exceed the number of votes cast "against" such nominee. In an uncontested election, if any incumbent director who is nominated for reelection does not receive a majority of the votes cast, the director must promptly tender his or her offer of resignation to the Board for consideration. In such event, the Board may decrease the number of directors on the Board, fill any vacancy, refuse to accept such offer of resignation or take other appropriate action. The Company's Amended and Restated Bylaws provide that directors will be elected by a plurality of the votes cast in contested elections. The resignation policy set forth in the Company's Amended and Restated Bylaws does not apply to contested elections.

        For voting purposes, proxies requiring confirmation of the date of beneficial ownership received by the Board of Directors with such confirmation not completed so as to show which Shares beneficially owned by the stockholder are entitled to five votes will be voted with one vote for each Share. See "Voting by Proxy and Confirmation of Beneficial Ownership" beginning on page 54.

        The Board of Directors recommends that you vote "FOR" the election of each of the four nominees listed below. Unless otherwise specified, proxies will be voted "FOR" the election of each of the four nominees listed below.

CORPORATE GOVERNANCE

A.  The Board of Directors

        The Company is governed by the Board of Directors and its various committees. The Board and its committees have general oversight responsibility for the affairs of the Company. In exercising its fiduciary duties, the Board represents and acts on behalf of the Company's stockholders. The Board has adopted written corporate governance guidelines and principles, known as the Statement of Corporate Governance Guidelines and Principles. The Board also has adopted a Business Code of Ethics, which applies to the Company's employees, executive officers (including the principal executive officer, principal financial officer and principal accounting officer) and directors. The Business Code of Ethics includes guidelines relating to the ethical handling of conflicts of interest, compliance with laws, accurate financial reporting and other related topics.

B.  Documents Available

        All of the Company's corporate governance materials, including the charters for the Audit Committee, the Compensation Committee and the Corporate Governance and Nominating Committee, as well as the Statement of Corporate Governance Guidelines and Principles and the Business Code of Ethics, are available on the Company's website at www.carlisle.com. These materials are also available in print without charge to any stockholder upon request by contacting the Company at Carlisle Companies Incorporated, 16430 North Scottsdale Road, Suite 400, Scottsdale, Arizona 85254, Attention: Secretary, or by telephone at (480) 781-5000. Any modifications to these corporate governance materials will be reflected, and the Company intends to post any amendments to, or waivers from, the Business Code of Ethics (to the extent required to be disclosed pursuant to Form 8-K) on the Company's website at www.carlisle.com. By referring to the Company's website, www.carlisle.com, or any portion thereof, the Company does not incorporate its website or its contents into this Proxy Statement.

C.  Director Independence

        The Board believes that a majority of its members are independent under the applicable NYSE rules and SEC rules. The NYSE rules provide that a director does not qualify as "independent" unless the board of directors affirmatively determines that the director has no material relationship with the company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the company). The NYSE rules recommend that a board of directors consider all of the relevant facts and circumstances in determining the materiality of a director's relationship with a company. In addition to the NYSE rules and the SEC rules, the Board has adopted director independence standards to assist the Board in determining whether a director has a material relationship with the Company. Under those standards, which are included in the Company's Statement of Corporate Governance Guidelines and Principles, a director will not be independent if, within the preceding three years: (i) the director was employed by the Company or received $100,000 per year in direct compensation from the Company, other than director and committee fees and pension or other forms of deferred compensation for prior service; (ii) the director was employed by or affiliated with the Company's independent registered public accounting firm; (iii) the director was part of an interlocking directorate in which an executive officer of the Company served on the compensation committee of another company that employed the director; (iv) the director was an executive officer or employee of another company that made payments to, or received payments from, the Company for property or services in an amount which, in any single fiscal year, exceeded the greater of $1 million or 2% of such other company's consolidated gross revenues; or (v) the director had an immediate family member in any of the categories in (i)—(iv).

Table of Contents

        In December 2018, the Board of Directors, with the assistance of the Corporate Governance and Nominating Committee, conducted an evaluation of director independence based on the Company's director independence standards, the NYSE rules and the SEC rules. The Board considered all relationships and transactions between each director (and his or her immediate family members and affiliates) and each of the Company, its management and its independent registered public accounting firm, as well as the transactions described below under "—Related Person Transactions." As a result of this evaluation, the Board determined those relationships that do exist or did exist within the last three years (except for Mr. Koch's current employment with the Company and Mr. Robert's prior employment with the Company) all fall well below the thresholds in the Company's director independence standards. Consequently, the Board of Directors determined that each of Messrs. Adams, Bohn, Collins, Frias, Growcock (who retired from the Board on May 2, 2018), Ostrander, Sala and Singh and Ms. Ricard is (and, in the case of Mr. Growcock, was) an independent director under the Company's director independence standards, the NYSE rules and the SEC rules. The Board also determined that each member of the Audit, Compensation and Corporate Governance and Nominating Committees (see membership information below under "—Board Committees") is independent, including that each member of the Audit Committee is "independent" as that term is defined under Rule 10A-3(b)(1)(ii) of the Exchange Act.

D.  Board Leadership Structure

        Currently, the Company has separated the roles of Chairman of the Board and Chief Executive Officer. David A. Roberts, a retired executive officer of the Company, serves as the Chairman of the Board and D. Christian Koch serves as the Company's President and Chief Executive Officer. The Company previously combined the roles of Chairman of the Board and Chief Executive Officer and, in the future, the Board may determine in certain circumstances that it is in the best interests of the Company and its stockholders for the same person to hold the positions of Chairman of the Board and Chief Executive Officer. Mr. Koch, as the Company's Chief Executive Officer, is responsible for providing the day-to-day leadership of the Company and carrying out the strategic direction of the Company, while Mr. Roberts, as the Chairman of the Board, provides guidance to Mr. Koch and sets the agenda for Board meetings and presides over meetings of the Board.

        The Board of Directors acknowledges that independent Board leadership is important, and, accordingly, the Company's Statement of Corporate Governance Guidelines and Principles provides that when the Company's Chief Executive Officer serves as Chairman of the Board or, as is currently the case, the Chairman is otherwise not considered independent, the independent directors shall elect a Lead Independent Director. The director then serving as Chair of the Corporate Governance and Nominating Committee also serves as the Lead Independent Director. The Lead Independent Director's duties closely parallel the role of an independent Chairman of the Board of Directors, to ensure an appropriate level of independent oversight for Board decisions. Mr. Bohn, as the Lead Independent Director, has the following responsibilities: (i) chairs all meetings of the Board of Directors at which the Chairman is not present and all executive sessions of the Board of Directors; (ii) liaises between the Chief Executive Officer and the independent directors; (iii) consults with the Chairman concerning (a) information to be sent to the Board of Directors, (b) meeting agendas and (c) meeting schedules to ensure appropriate time is provided for all agenda items; (iv) calls meetings of independent directors as required; and (v) is available when appropriate for consultation, including stockholder communications. In addition, the Lead Independent Director presides over an executive session of the independent directors at every regularly scheduled meeting of the Board of Directors. The Board of Directors believes that the existence of a Lead Independent Director, the scope of the Lead Independent Director's responsibilities and the regularly scheduled executive sessions of the independent directors all support strong corporate governance principles and allow the Board to effectively fulfill its fiduciary responsibilities to stockholders.

Table of Contents

        In addition, as previously noted, all of the Company's directors (other than Mr. Roberts, a retired executive officer of the Company, and Mr. Koch, the Company's President and Chief Executive Officer) and each member of the Audit, Compensation and Corporate Governance and Nominating Committees meet the independence requirements of the New York Stock Exchange (the "NYSE"). Therefore, independent directors directly oversee such critical matters as the integrity of the Company's financial statements, the compensation of executive management, the selection and evaluation of directors and the development and implementation of the Company's corporate governance policies and structures. In addition, the Compensation Committee conducts an annual performance review of Mr. Koch, and, based upon this review, makes recommendations for his compensation (including base salary and annual incentive and equity compensation) for approval by the independent members of the Board.

E.  Board Committees

        The Board has three standing committees: (i) the Audit Committee, (ii) the Compensation Committee and (iii) the Corporate Governance and Nominating Committee. Committee members and committee chairs are appointed by the Board of Directors. The members of these committees are identified in the following table:

        The Board of Directors has also adopted a committee chair rotation guideline. Under the guideline, effective as of the date of each annual meeting of stockholders, a committee chair will relinquish his or her chairmanship. The guideline will result in each committee chair typically serving for three years. The Board of Directors believes bringing new leadership to each of the committees every three years will enhance the effectiveness of the committees. In accordance with this guideline, Mr. Adams succeeded Mr. Growcock (who retired from the Board on May 2, 2018) as Chair of the Compensation Committee at the 2018 Annual Meeting of Stockholders.

        Each committee of the Board of Directors functions pursuant to a written charter adopted by the Board. Set forth below is a summary of the principal functions of each committee.

        Audit Committee.    The Audit Committee has the sole authority to appoint and terminate the engagement of the Company's independent registered public accounting firm. The functions of the Audit Committee also include reviewing the arrangements for and the results of the independent registered public accounting firm's examination of the Company's books and records, the Company's internal accounting control procedures, the activities and recommendations of the Company's internal

16

auditors, and the Company's accounting policies, control systems and compliance activities, and monitoring the funding and investment performance of the Company's defined benefit pension plan. During fiscal 2018, the Audit Committee held six meetings.

        Compensation Committee.    The Compensation Committee administers the Company's annual and long-term, stock-based incentive programs and decides upon annual salary adjustments for various employees of the Company, including the Company's executive officers. During fiscal 2018, the Compensation Committee held three meetings.

        Corporate Governance and Nominating Committee.    The Corporate Governance and Nominating Committee develops and maintains the Company's corporate governance guidelines and principles, leads the search for individuals qualified to become members of the Board and recommends such individuals for nomination by the Board to be presented for stockholder approval at the Company's annual meetings, reviews the Board's compensation and committee structure and recommends to the Board, for its approval, directors to serve as members of each committee, discusses succession planning and recommends a new chief executive officer if a vacancy occurs. During fiscal 2018, the Corporate Governance and Nominating Committee held two meetings.

        The Board may also establish other committees from time to time as it deems necessary.

F.  Director Meeting Attendance

        The Board of Directors held six meetings during fiscal 2018. Each incumbent director attended 75% or more of the aggregate number of meetings of the Board and committees of the Board on which the director served during fiscal 2018. While directors are not required to attend the Company's annual meeting of stockholders, all 11 of the Company's directors in office at the time attended the 2018 Annual Meeting of Stockholders.

        At the conclusion of each of the regularly scheduled Board meetings, the independent directors meet in executive session without management. Mr. Bohn, as the Lead Independent Director, presides over these executive sessions.

G.  Director Nomination Process

        As more fully described in its Charter, the Corporate Governance and Nominating Committee assists the Board by identifying and evaluating individuals qualified to be directors and by recommending to the Board such individuals for nomination as members. Pursuant to the Company's Statement of Corporate Governance Guidelines and Principles, director nominees should possess the highest personal and professional integrity, ethics and values, and be committed to representing the long-term interests of the Company's stockholders. Nominees should also have outstanding business, financial, professional, academic or managerial backgrounds and experience. Each nominee must be willing to devote sufficient time to fulfill his or her duties, and should be committed to serve on the Board for an extended period of time. Prior to accepting an invitation to serve on another public company board, directors must advise the Corporate Governance and Nominating Committee, which will determine whether such service would create a conflict of interest and/or prevent the director from fulfilling his or her responsibilities to the Company.

        Neither the Corporate Governance and Nominating Committee nor the Board has a specific policy with regard to the consideration of diversity in identifying director nominees. However, the Board values diversity and the Corporate Governance and Nominating Committee has consistently included diversity as a desired qualification when conducting searches for director nominees. The composition of the Board reflects its emphasis on diversity.

        The Corporate Governance and Nominating Committee may, at its discretion, hire third parties to assist in the identification and evaluation of director nominees. All director nominees, including those

appropriately recommended by stockholders, are evaluated in accordance with the process described above.

H.  Stockholder Recommendations of Director Nominees

        Stockholders may recommend director nominees to be considered for the Company's 2020 Annual Meeting of Stockholders by submitting the director nominee's name in accordance with provisions of the Company's Restated Certificate of Incorporation, which require advance notice to the Company and certain other information. Written notice must be received by the Company's Secretary at Carlisle Companies Incorporated, 16430 North Scottsdale Road, Suite 400, Scottsdale, Arizona 85254 not less than 90 days prior to the first anniversary of the Annual Meeting. As a result, any director nominations submitted by a stockholder pursuant to the provisions of the Company's Restated Certificate of Incorporation must be received no later than February 8, 2020.

        The notice must contain certain information about the nominee and the stockholder submitting the nomination, as set forth in the Company's Restated Certificate of Incorporation, including (i) the name, address and qualifications of the stockholder submitting the nomination; (ii) the name, age, business address and, if known, residence address of each nominee proposed in such notice; (iii) the principal occupation or employment of each such nominee; (iv) the number of shares of capital stock of the Company of which each such nominee is the "Beneficial Owner" (as defined in the Company's Restated Certificate of Incorporation); and (v) such other information as would be required by the securities laws of the United States and the rules and regulations promulgated thereunder in respect of an individual nominated as a director of the Company and for whom proxies are solicited by the Board of Directors of the Company. The presiding officer at the 2020 Annual Meeting of Stockholders may refuse to accept any such nomination that is not in proper form or submitted in compliance with the procedure set forth in the Company's Restated Certificate of Incorporation. A stockholder who is interested in recommending a director nominee should request a copy of the Company's Restated Certificate of Incorporation by writing to the Company's Secretary at Carlisle Companies Incorporated, 16430 North Scottsdale Road, Suite 400, Scottsdale, Arizona 85254.

I.  Related Person Transactions

        The Board has adopted a written policy concerning the review, approval and monitoring of transactions involving the Company and "related persons" (i.e., directors, director nominees and executive officers of the Company or their immediate family members, or stockholders owning more than 5% of the outstanding Common Shares). The policy covers any transaction exceeding $120,000 in which the related person has a direct or indirect material interest. Related person transactions must be approved by the Corporate Governance and Nominating Committee which will approve the transaction only if it determines that the transaction is in the best interest of the Company. In the course of its review and, if appropriate, approval of a related person transaction, the Corporate Governance and Nominating Committee considers all of the relevant facts and circumstances, including the material terms of the transaction, the risks, benefits and costs of the transaction, the availability of other comparable services or products and, if applicable, the impact on a director's independence.

        In fiscal 2018, in accordance with the requirements of the Company's related person transaction policy, the Corporate Governance and Nominating Committee reviewed the fleet management services that Emkay Incorporated ("Emkay") provides to Carlisle Construction Materials, LLC, a wholly-owned subsidiary of the Company ("CCM"). The Company paid Emkay a management fee of $60,608 and reimbursed Emkay $3,029,746 for pass-through costs, such as fuel, taxes, vehicle depreciation and other related costs. Emkay has provided fleet management services as a preferred vendor to CCM since 1997. A brother-in-law of Mr. Roberts (the Company's Chairman of the Board) is a senior officer and more than 10% owner of Emkay. The Corporate Governance and Nominating Committee considered all of the relevant facts and circumstances related to the services provided by Emkay and approved the

Table of Contents

continuation of Emkay's services to CCM. The Corporate Governance and Nominating Committee will continue to review annually the Company's business relationships with Emkay.

J.  The Board's Role in Risk Oversight

        Risk management is a significant component of management's annual strategic and operating planning processes. The Company has adopted an enterprise risk management program to identify and mitigate enterprise risk. Under the program, each operating business is required to identify risks to its business and prepare a detailed plan to mitigate those risks. The division presidents present the plans to executive management as part of their strategic and operating plans. Over the course of each fiscal year, the division presidents provide similar presentations to the Board of Directors at the meetings covering the Company's business plans. Each year the Board also reviews and discusses reports on the Company's ongoing litigation, cybersecurity risks and insurance coverages.

        The Compensation Committee, in consultation with the committee's compensation consultant, periodically reviews the relationship between the Company's compensation practices and risk. The Compensation Committee has concluded that the Company's compensation practices are not reasonably likely to have a material adverse effect on the Company and do not encourage inappropriate risk taking. The Compensation Committee's conclusion was based on the following:

•

Annual cash bonuses at maximum performance levels are capped by the Compensation Committee at 220% of base salary for the President and Chief Executive Officer and 150% of base salary for the other named executive officers.



•

Annual cash bonuses are based on multiple balanced performance metrics.



•

The threshold, target and maximum performance levels for each of the annual cash bonus performance metrics are based on prior year performance adjusted to reflect the current year Company business plan, which has been reviewed and approved by the Board of Directors, and general market expectations. The Company's Chief Financial Officer actively participates in the Compensation Committee meetings during which the performance levels are set and the performance results are verified.



•

The annual cash bonus payout curve from threshold to maximum is a straight line (linear) progression.



•

The target grant value of the Company's long-term, stock-based awards are fixed at 375% of base salary for the President and Chief Executive Officer and 150% of base salary for the other named executive officers.



•

The stock-based awards include an equally weighted mix of stock options, restricted Shares and performance Shares. Stock options and restricted Shares are subject to three-year vesting periods and performance Shares are earned over a three-year performance period.



•

The Compensation Committee has adopted a stock ownership policy that requires significant stock ownership by the Company's executives.



•

The Compensation Committee has adopted a clawback policy, effective January 1, 2019, under which the committee may elect to seek recovery of excess incentive-based compensation paid to an executive officer for up to three years prior to a material accounting restatement.



•

The Company has adopted guiding principles that govern plan design. The executive compensation program is documented, communicated and monitored on a consistent basis.

The Compensation Committee has and will continue to conduct assessments of the relationship between the Company's compensation practices and risk periodically and in connection with the

adoption of any new material compensation programs or any material changes to existing compensation programs.

K.  Communications with the Board of Directors

        Stockholders and other interested parties can communicate directly with any of the Company's directors by sending a written communication addressed to such director at Carlisle Companies Incorporated, 16430 North Scottsdale Road, Suite 400, Scottsdale, Arizona 85254, Attention: Secretary. Stockholders and other interested parties wishing to communicate with Mr. Bohn, as the Lead Independent Director, or with the independent directors as a group may do so by sending a written communication addressed to Mr. Bohn at the above address. Any communication addressed to any director that is received at the Company's principal executive offices will be delivered or forwarded to the individual director as soon as practicable. All such communications are promptly reviewed before being forwarded to the addressee. The Company generally will not forward to directors a communication that the Company determines to be primarily commercial in nature, relates to an improper or irrelevant topic or requests general information about the Company.

DIRECTOR COMPENSATION

        The Company paid an annual fee of $80,000 in 2018 to each non-employee director, except for Mr. Roberts who received a fee of $225,000 for his service as Chairman of the Board. The annual fees are determined by the Board of Directors. Each non-employee director may elect to receive one-half of the annual fee in Shares. Directors do not receive meeting attendance fees.

        The Company also pays an annual fee for service on the Board's committees. In 2018, each member of the Audit Committee received an annual fee of $15,000 and each member of the Compensation and Corporate Governance and Nominating Committees received an annual fee of $8,500. In 2018, the Chairman of the Audit Committee received an additional annual fee of $15,000 and the Chairman of the Compensation Committee received an additional annual fee of $12,500. The Chairman of Corporate Governance and Nominating Committee, who also served as the Lead Independent Director, received an additional annual fee of $30,000 in 2018.

        In addition to the annual fee and committee fees, each non-employee director is eligible to participate in the Incentive Compensation Program. The Incentive Compensation Program provides for the grant of stock options, stock appreciation rights, restricted Shares or units or other stock-based awards to non-employee directors. The Board administers the Incentive Compensation Program with respect to awards to non-employee directors and has the discretionary authority to make all award decisions under the Incentive Compensation Program. At the meeting of the Board of Directors held on February 6, 2018, the Board of Directors awarded each eligible director (other than Mr. Roberts) an award of 1,196 restricted Share units having a grant date value of approximately $130,000 based on the closing market price of a Common Share on February 6, 2018. Under the current policy of the Board, each new director receives an award of restricted Share units having a value of approximately $50,000. All restricted Share units awarded to eligible directors are fully vested and will be paid in Shares after the director ceases to serve as a member of the Board, or, if earlier, upon a change of control of the Company. Mr. Roberts received an award of 2,070 restricted Share units having a grant date value of approximately $225,000 based on the closing market price of a Common Share on February 6, 2018.

        In December 2018, the Corporate Governance and Nominating Committee reviewed the compensation payable to non-employee directors and a market analysis report by Willis Towers Watson, an independent compensation consulting firm. After considering the report, the Corporate Governance and Nominating Committee recommended, and the Board approved, the following changes with respect to non-employee director compensation to be effective January 1, 2019: (i) a $5,000 increase in the annual fee from $80,000 to $85,000 (and from $225,000 to $230,000 for Mr. Roberts as Chairman of the Board); (ii) a $5,000 increase in the annual fee for the Chairman of the Audit Committee from $15,000 to $20,000; (iii) a $2,500 increase in the annual fee for the Chairman of the Compensation Committee from $12,500 to $15,000; (iv) a $5,000 increase in the annual fee for the Chairman of the Corporate Governance and Nominating Committee (who also serves as the Lead Independent Director) from $30,000 to $35,000; and (v) a $5,000 increase in the annual equity portion of each non-employee director's compensation from $130,000 to $135,000 (and from $225,000 to $230,000 for Mr. Roberts as Chairman of the Board).

        The Company also maintains the Carlisle Companies Incorporated Deferred Compensation Plan for Non-Employee Directors (the "Deferred Compensation Plan"). Under the Deferred Compensation Plan, each non-employee director of the Company is entitled to defer up to 100% of the cash fees otherwise payable to him or her. Each participant can direct the "deemed investment" of his or her deferral account among the different investment funds offered by the Company from time to time. The investment options include a fixed rate fund and Share equivalent units. All amounts credited to a participant's account under the Deferred Compensation Plan are 100% vested and generally will be paid or commence to be paid after the participant terminates service as a director. At the participant's

21

---

Table of Contents

election, payments can be made in a lump sum or in quarterly installments over a 10-year period. Payments under the Deferred Compensation Plan are made in cash from the Company's general assets.

        The Board of Directors has adopted stock ownership guidelines for non-employee directors. The stock ownership guidelines require each non-employee director to own Shares, restricted Share units and Share equivalent units under the Deferred Compensation Plan having a market value equal to six times the annual fee amount within five years of him or her becoming a director. Once the required market value ownership level is achieved, no further purchases are required in the event the value of the Shares held by a director falls below the ownership level due solely to a decrease in the market value of the Shares. As of December 31, 2018, each of the directors who has been a member of the Board for at least five years met the stock ownership requirement. The stock ownership guidelines prohibit a director from using Shares as collateral for any purpose or engaging in short sales or hedging transactions involving Shares.

        The table below sets forth the compensation paid to each non-employee director who served on the Board in fiscal 2018. Directors who are also employees of the Company (currently Mr. Koch) do not receive compensation (other than their compensation as employees of the Company) for their service on the Board of Directors.

COMPENSATION DISCUSSION AND ANALYSIS

        This section contains an in-depth discussion and analysis of the Company's executive compensation policies and practices and the compensation earned by the Company's most senior executives (referred to as the "named executives" or the "named executive officers" in this section) under those policies and practices. The Compensation Committee of the Board of Directors administers the Company's compensation policies and practices for all executive officers of the Company, including the named executives.

        As you review this section, you will see that the Compensation Committee has adopted executive compensation policies and practices that (i) link pay and performance—with Company executives having the opportunity to earn substantial compensation over and above their base salaries based on the Company's performance or the market value of the Shares, (ii) align the interests of the Company's executives and stockholders, (iii) are transparent and easy to communicate to the Company's executives and stockholders and (iv) provide a valuable retention tool for key executive talent.

A.  Executive Summary

        In 2017, management developed Vision 2025, a strategic vision for the Company built on the foundation and core capabilities established over the Company's long history and based on creating sustainable value for stockholders through repeatable execution of solid plans. A critical factor to achieving the Vision 2025 strategic goals is the contributions of motivated employees. Accordingly, the Company's annual incentive compensation program will continue to be directly linked to key financial goals and will award annual incentive compensation to the named executives based on the Company's progress toward achieving the Vision 2025 strategic goals for the Company.

        The executive compensation program provides a further link between executive pay and stockholder interests by including performance Shares and stock options in the long-term stock-based awards made under the program. The performance Shares are earned based on the total return to the Company's stockholders (Share appreciation plus dividends) relative to the total stockholder return of the companies comprising the S&P MidCap 400 Index® over three-year performance periods. The value of the earned performance Shares and the stock options is directly linked to the market value of the Shares. The Company's stockholders endorsed the executive compensation program at the 2018 Annual Meeting of Stockholders where approximately 95% of the votes cast were in favor of a resolution approving the compensation earned by the named executive officers under the program in 2017 (the "say-on-pay proposal").

        The Company continued its journey to its 2025 strategic vision by continuing implementation of the Carlisle Operating System, divesting non-strategic assets, investing in new acquisitions and strengthening its management talent. In 2018, the continuing strong operational performance of the Company produced positive financial results and enabled the Company to return capital to stockholders through increased dividends and Share repurchases.

Table of Contents

        The table below summarizes the Company's annual incentive performance measures for 2018 and 2017 selected by the Compensation Committee for determining the annual incentive compensation for the named executive officers.

Annual Incentive Performance Measures(1)

        In 2018, the Compensation Committee refined the performance measures on which the 2018 annual incentive awards were based, as described on pages 27 through 30. The refinements were made to more accurately align the measures with the Company's Vision 2025 strategic goals. Otherwise, the Compensation Committee did not make significant changes in the principal features of the executive compensation program for 2018. As described in this section, the Compensation Committee took the following compensation actions in 2018 with respect to the named executives:

•

Increased the base salaries of the named executive officers in line with market conditions, as described on page 27;



•

Paid 2018 annual incentive awards ranging from 67% to 196% of the target award levels based upon Company-wide or Company business unit performance, as described on pages 27 through 30;



•

Based on the Company's total stockholder return (Share appreciation plus dividends) for the three-year period ended December 31, 2018 of 23.3% relative to the total stockholder return of the S&P MidCap 400 Index® for the same period of 38.1%, paid performance Shares for the three-year performance period that ended in 2018 at 84% of the target award level based on the Company's total stockholder return during the period ranking in the 42^nd percentile of the S&P MidCap 400 Index®; and



•

Issued long-term incentive awards, as described on pages 30 through 31.

        The Company's stockholders will have the opportunity to provide feedback to the Board of Directors on the Company's executive compensation program through the say-on-pay proposal at the Annual Meeting. The Compensation Committee encourages all of the Company's stockholders to carefully review this section and the disclosure tables that follow this section prior to casting their votes on the say-on-pay proposal included as Proposal 3 in this Proxy Statement.

B.  Roles of Compensation Committee, Compensation Consultant and Executive Officers in Determining Executive Compensation

        The Compensation Committee renewed its engagement of Willis Towers Watson as the executive compensation consultant to the committee for 2018. Willis Towers Watson provides no services to the Company or its management other than services related to the Company's executive and non-employee

24

Table of Contents

director compensation programs. The Compensation Committee has determined that Willis Towers Watson is independent from the Company and its executive officers and that the services provided by Willis Towers Watson do not raise any conflict of interest.

        In 2018, Willis Towers Watson presented an executive compensation report to the Compensation Committee highlighting executive pay levels and design and updates on (i) the compensation governance environment, (ii) proxy advisor and institutional investor concerns and (iii) legal and regulatory issues.

        The Compensation Committee also receives input from Company management in connection with the administration of the Company's executive compensation program. Mr. Koch, the Company's President and Chief Executive Officer, recommended base salary increases for the named executive officers (other than himself), and the Compensation Committee approved the recommendations. In addition, Mr. Koch provided input to the Compensation Committee about the refinements made to the performance measures used for determining the 2018 annual incentive awards (other than for himself), the threshold, target and maximum performance levels for the performance measures and the weighting of each performance measure.

        Mr. Roche, the Company's Vice President and Chief Financial Officer, provided information and analysis to the Compensation Committee about the financial performance of the Company for fiscal 2018 and each of the Company's operating businesses for which a named executive officer was responsible. The Compensation Committee used the information and analysis provided by Mr. Roche in determining the annual incentive awards earned by the named executives for 2018.

C.  Philosophy and Material Elements of Executive Compensation Program; 2018 Compensation Actions

        The material elements of the total direct compensation provided to executives under the Company's executive compensation program are (i) base salary, (ii) a target annual cash bonus opportunity expressed as a percentage of each executive's base salary and (iii) a long-term, stock-based award, the expected value of which is also expressed as a percentage of base salary. While each element of compensation paid to executive officers is significant, the annual cash bonus and the long-term, stock-based award have the potential to be the largest amounts of the total compensation paid to executive officers.

        The following table shows the guiding principles for the Company's executive compensation program and how the program complies with these principles:

Compensation Benchmarking

        The Compensation Committee periodically benchmarks executive compensation to ensure the compensation provided to Company executive officers is reasonable and competitive with the market. While compensation was not benchmarked in 2018, the executive compensation report presented to the Compensation Committee by Willis Towers Watson generally confirmed the appropriateness of the Company's executive compensation program, including the long-term, stock-based awards and the use of relative total stockholder return as the performance measure for the Company's performance Share awards.

Table of Contents

Base Salaries

        Base salaries provide a baseline level of compensation to executive officers for carrying out the day-to-day duties and responsibilities of their positions.

        The Compensation Committee reviews and adjusts base salary levels each year. During the review and adjustment process, the Compensation Committee considers:

•

the duties and responsibilities of each executive officer position;



•

the executive officer pay relative to the base salaries of senior officers and other employees of the Company; and



•

whether the base salary levels are competitive, based on a comparison of the current base salary with the market base salary.

        The Compensation Committee reviews the named executive officer base salaries in December each year. Any base salary increases approved in December become effective for the succeeding fiscal year. In December 2018, the Company approved the following base salaries for the named executives effective for fiscal 2019:

        The Compensation Committee approved increases based on trends in the market indicating average salary increases of 3%. Mr. Roche received a larger than average increase to reflect his additional responsibilities for investor relations.

2018 Annual Incentive Awards

        The Company's executive officers earned annual incentive compensation under the Incentive Compensation Program for 2018 based on the overall performance of the Company or a Company business unit compared to pre-established performance measures.

        The Compensation Committee first established a target annual incentive award expressed as a percentage of each named executive's base salary. The 2018 target awards were 110% of base salary for Mr. Koch and 75% of base salary for the other named executives.

        The Compensation Committee then selected the performance measures on which the 2018 annual incentive awards would be based. The measures adopted for the 2018 annual incentive awards to Mr. Koch, Mr. Roche and Mr. Ford were the Company's consolidated (i) sales, (ii) operating income margin, (iii) average working capital as a percentage of sales and (iv) earnings. The measures adopted for the 2018 annual incentive awards to the other named executive officers were (i) sales, (ii) operating income margin, (iii) average working capital as a percentage of sales, each as reported by their respective business units, and (iv) the Company's consolidated earnings. The Compensation Committee believes that each of these respective performance measures tracks whether the Company and its core businesses are operating efficiently and with a view toward long-term, sustainable growth in the United States and globally. The Compensation Committee believes that superior performance under these

27

---

Table of Contents

measures will ultimately benefit Company stockholders through increased profits, dividends and Share value.

        Finally, the Compensation Committee established threshold, target and maximum levels of performance for each of the measures and determined that 50% of the target annual incentive award would be paid for threshold level performance, 100% of the target annual incentive award would be paid for target level performance and 200% of the target annual incentive award would be paid for performance at or above the maximum level. Under the program adopted by the Compensation Committee, the Company's performance under each of the measures was independently determined from the other measures, so that an annual incentive award was determined for the actual level of performance under each measure. The annual incentive awards under each measure were then combined to determine the aggregate annual incentive award.

        The Compensation Committee approved threshold, target and maximum performance levels for 2018 based on the Company's 2017 adjusted performance. The tables below show the threshold, target and maximum performance levels for each of the performance measures established by the Compensation Committee for 2018 as well as the Company's adjusted performance in 2018 and 2017. The results shown below for both 2017 and 2018 reflect the Company's publicly reported results, excluding results from acquisitions made and acquisition costs incurred during the respective year and the results of Carlisle Foodservice Products, Inc., which was divested in 2018. The 2017 results have also been adjusted to exclude approximately $35.7 million (pre-tax) in restructuring charges and facility rationalization costs at Carlisle Fluid Technologies, Inc., Carlisle Brake & Friction, Inc. and Carlisle Interconnect Technologies, Inc. and to reclassify approximately $2.4 million (pre-tax) of operating income through retrospective application of Accounting Standards Update ("ASU") 2017-07. The 2018 results have also been adjusted to exclude approximately $32.7 million (pre-tax) in restructuring charges and facility rationalization costs at Carlisle Fluid Technologies, Inc., Carlisle Brake & Friction, Inc. and Carlisle Interconnect Technologies, Inc. The 2018 results also exclude sales of approximately $21.9 million and operating income of approximately $7.2 million to adjust for the Company's adoption of the revenue recognition standard in ASU 2014-09. The Compensation Committee approved the adjustments because they are generally nonrecurring or were not anticipated when the respective performance measures were approved at the beginning of the year.

        Based on the performance measures established by the Compensation Committee for 2018 and the Company's actual performance, the named executives earned 2018 annual incentive awards as follows:

2018 Long-Term, Stock-Based Awards

Annual Awards

        The Compensation Committee makes annual stock-based awards each year at its regularly scheduled February meeting. All stock-based awards are made under the Incentive Compensation Program which imposes certain restrictions, as described below, on the terms of the awards.

        In February 2018, the Compensation Committee awarded stock options, performance Shares and restricted Shares to the named executives in the amounts shown in the Grants of Plan-Based Awards Table on page 38. The number of Shares included in the 2018 awards was determined using a formula-based approach. First, the Compensation Committee established a target award opportunity, expressed as a percentage of base salary, for the named executives based on each executive's position and the long-term incentive award market range for that position: 375% of base salary for the Chief Executive Officer and 150% of base salary for the other named executives.

        The Compensation Committee then determined the appropriate blend of the types of equity awards to be included in each named executive's stock-based award. In 2010, the Compensation Committee changed the blend of equity awards from stock options and time-vested restricted Shares (each weighted 50%) to stock options, performance Shares and time-vested restricted Shares (each weighted 33¹/3%) and elected to use the same blend of stock-based awards in 2018 for all the named executives to support the Company's pay-for-performance programs and the alignment of executive and stockholder interests.

        All stock-based awards to the Company's senior management employees (approximately 90 employees, including all of the named executives) contain a non-competition agreement that prohibits the grantee from competing with the Company for one year following his or her termination of employment.

        The stock options awarded in February 2018 will vest in equal annual installments over three years. The restricted Shares awarded in 2018 will become vested on the January 1 immediately preceding the third anniversary of the award date.

        The performance Shares awarded in February 2018 will be earned based on the total return to the Company's stockholders (Share appreciation measured using the average of the closing market prices for a Share for the first 10 and last 10 trading days of the performance period plus dividends) relative

30

Table of Contents

to the total stockholder return of the companies comprising the S&P MidCap 400 Index® over the three-year performance period ending December 31, 2020 in accordance with the following table:

        If the Company's total stockholder return falls between the 25^th and 50^th percentiles or between the 50^th and 75^th percentiles, the number of performance Shares earned will be determined by linear interpolation. Dividends will accrue during the three-year performance period and will be paid on performance Shares that are earned.

        The Compensation Committee included stock options in the awards to encourage the named executives to increase stockholder value over the 10-year term of the options. The Compensation Committee included restricted Shares in the awards not only to encourage the named executives to increase stockholder value but also to remain employed with the Company. The Compensation Committee added performance Shares to further link executive compensation to the performance of the Company and to align the interests of the executives with the Company's stockholders.

        The Incentive Compensation Program contains certain restrictions on the terms of all stock-based awards. For example, all stock options must be granted with an option exercise price that is equal to or greater than the fair market value of the Shares on the date of award. The Incentive Compensation Program also expressly prohibits resetting the option exercise price of stock options. These restrictions ensure that any options awarded under the Incentive Compensation Program will have value to the executives only if the market price of the Shares increases after the date of the award. The Incentive Compensation Program further requires that restricted Share awards must be subject to a restriction period of not less than one year during which the Shares are subject to a substantial risk of forfeiture and may not be transferred. As a result of changes made to Section 162(m) of the Internal Revenue Code (the "Code") applicable to 2018 compensation, the Compensation Committee approved an amendment to the Incentive Compensation Program, effective January 1, 2019, to eliminate the limits on the size of the annual awards that may be granted to any executive. The Compensation Committee also approved an amendment to the Incentive Compensation Program, effective January 1, 2019, to allow the Company's Chief Executive Officer to approve off-cycle grants of stock-based awards to employees other than Section 16 officers for limited purposes and subject to volume limits approved by the Compensation Committee.

        The Compensation Committee has never altered the timing of stock-based awards to take advantage of non-public information. The Compensation Committee is aware that the February meeting during which it makes annual stock-based awards precedes the date the Company releases its fourth quarter and annual financial results. The Compensation Committee is also aware that the release could affect the market value of the Company's stock and the underlying value of the stock-based awards made to executives at the February meeting. The Compensation Committee believes that executives will not necessarily gain over the long run from the short-term benefit of a positive release because the Company's stock price fluctuates over time and because all of the awards have multi-year vesting schedules and stock options have historically been held for several years prior to exercise. In addition, any gain from a positive benefit in some years will be offset by earnings releases in other years that negatively affect the market value of the Shares.

Stock Ownership Policy

        The Compensation Committee believes that ownership of Common Shares by executive officers aligns their interests with those of the Company's stockholders, enhances retention of executives by providing them an opportunity to accumulate a meaningful ownership interest in the Company and focuses executives on building stockholder value over the long term. Therefore, the Compensation Committee has maintained for several years a stock ownership policy for the Company's executive officers, including the named executives. In December 2018, the Compensation Committee amended the stock ownership policy to better align the policy with current comparable practices.

        The amended policy, which is applicable to all of the Company's Section 16 officers, has the following ownership requirements:

        The policy also has a retention requirement under which an executive officer must retain at least one-half of the after-tax value realized from the vesting of restricted Shares, the exercise of stock options or the receipt of earned performance Shares until the executive officer has satisfied the policy's ownership requirement. Each executive officer subject to the policy has five years from first becoming subject to the policy to attain the ownership requirement and once the ownership requirement is met, no further accumulation is required in the event the value of the Shares falls below the ownership requirement due solely to a decrease in the market value of the Shares.

        Ownership for purposes of the policy includes Shares owned directly or under an employee benefit plan and all restricted Shares. Ownership does not include any performance Share awards or any Shares subject to stock options. As of February 28, 2019, the Chief Executive Officer and each of the individuals who has been a Section 16 officer for at least five years met the policy's ownership requirement.

        The stock ownership policy prohibits any executive officer from using Shares as collateral for any purpose or engaging in short sales or hedging transactions involving Shares.

D.  Retirement and Other Benefits

Retirement and Group Insurance Benefits

        The Company provides retirement, health and welfare and other benefits to its executive officers. The Company sponsors the 401(k) Plan, a tax-qualified, defined contribution retirement plan, for the benefit of substantially all of its non-union employees, including the named executives. The 401(k) Plan encourages saving for retirement by enabling participants to save on a pre-tax basis and by providing Company matching contributions.

        The Company also sponsors the Retirement Plan for Employees of Carlisle, LLC (the "Retirement Plan"), a tax-qualified, defined benefit retirement plan that provides retirement income to eligible employees following their retirement from the Company. The Pension Benefits Table on page 43 shows the lump sum present value as of December 31, 2018 of the accumulated benefit earned by the named executives under the Retirement Plan.

32

---

Table of Contents

        Section 401(a)(17) of the Code limits the amount of annual compensation that tax-qualified plans like the 401(k) Plan and the Retirement Plan may take into account for purposes of determining contributions and benefits. The limit for 2018 was $275,000 and it is subject to adjustment annually for cost of living increases. For 2019, the limit will be $280,000. The Company maintains the Carlisle, LLC Supplemental Pension Plan (the "Supplemental Pension Plan") to provide benefits to certain Retirement Plan participants whose benefits are limited by Section 401(a)(17) of the Code and to certain senior management employees who were employed on or after January 1, 2005 and are not eligible to participate in the Retirement Plan. The Pension Benefits Table on page 43 also shows the lump sum present value as of December 31, 2018 of the accumulated benefit earned by the named executives under the Supplemental Pension Plan.

        The Company sponsors a supplemental 401(k) Plan to provide covered officers, including the named executives, the opportunity to defer (i) base salary and annual incentive compensation that could not be deferred under the 401(k) Plan due to the Code limitations that apply to the 401(k) Plan and (ii) Shares earned under the Incentive Compensation Program. The Company provides a matching contribution equal to 100% of the first 4% of base salary and annual incentive compensation deferred under the supplemental 401(k) Plan. Each participant in the supplemental 401(k) Plan may direct the deferrals of base salary or annual incentive compensation and the matching contributions among the different investment options offered by the Company from time to time. The investment options currently include a fixed rate fund and various stock index funds. All amounts credited to a participant's account under the supplemental 401(k) Plan are 100% vested and will be paid in a lump sum or installments in accordance with the participant's election after the participant terminates employment with the Company. A participant may also elect to receive one or more in-service distributions.

        The named executives also participate in group health, life and other welfare benefit plans on the same terms and conditions that apply to other employees. The named executives do not receive better insurance programs, vacation schedules or holidays, and perquisites are limited.

Post-Termination Employment Benefits

        The Company has not entered into an employment agreement with any executive officer that provides severance or other benefits following their resignation, termination, retirement, death or disability, except for agreements with certain executive officers (including all of the named executives) that provide severance benefits in the event of a termination of their employment following a change of control of the Company (the "change of control agreements"). The change of control agreements provide that the executives will not, in the event of the commencement of steps to effect a change of control (defined generally as an acquisition of 20% or more of the outstanding voting Shares or a change in a majority of the Board of Directors), voluntarily leave the employ of the Company until the potential acquirer of the Company or control of the Company has terminated its efforts to effect a change of control or until a change of control has occurred. The Company believes that the change of control agreements protect the interests of the Company's stockholders by providing financial incentives to executives to represent the best interests of the Company and its stockholders during the periods immediately preceding and following a change of control.

        In the event of any termination of an executive's employment (including due to the executive's resignation) within three years after a change of control (other than due to the executive's death or disability or after the executive attains age 65), each change of control agreement provides that the executive will be entitled to receive three years' compensation, including bonus, retirement benefits equal to the benefits the executive would have received had he or she completed three additional years of employment, continuation of all life, accident, health, savings and other fringe benefits for three years and relocation assistance. The three-year benefit period is reduced if the executive terminates within three years of the date the executive would attain age 65. In addition, the agreements provide

33

---

Table of Contents

that the executive will become fully vested in all outstanding stock option and restricted Share awards. Under the Incentive Compensation Program, in the event the executive's employment is terminated without cause or the executive resigns with good reason within three years after a change of control of the Company, the outstanding performance Shares will be earned at the maximum level. If any payments to a named executive are considered excess "parachute payments"¹ and the amount of the excess is more than 15%, the Company is required to provide a tax gross up for the excise taxes the executive would be required to pay with respect to the payments.

        In September 2012, the Compensation Committee determined that any future change of control agreements would provide severance benefits only in the event an executive is terminated without cause or resigns with good reason within three years after a change of control and the severance benefits would not be reduced based on the executive's age. In addition, the Company would not provide any tax gross up for excise taxes assessed against any excess parachute payments.

Internal Revenue Code Section 162(m)

        Section 162(m) of the Code limits the amount of compensation paid to the named executives in any one fiscal year that may be deducted by the Company for federal income tax purposes. The deduction limitation is currently $1 million.

        The Tax Cuts and Jobs Act of 2017 expanded the number of individuals covered by Section 162(m) of the Code and eliminated the exception for performance-based compensation effective for the Company's 2018 tax year. Therefore, compensation in excess of $1 million paid to named executives in 2018 and later years will not be deductible unless it qualifies for transition relief applicable to certain arrangements in place as of November 2, 2017.

        The Compensation Committee has not adopted a formal policy that requires all compensation paid to the named executives to be fully deductible.

E.  Conclusion

        The Compensation Committee has reviewed all components of the Chief Executive Officer's and the other named executives' compensation, including salary, bonus, equity and long-term incentive compensation, accumulated realized and unrealized stock option and restricted Share gains and the dollar value of all perquisites and other personal benefits as well as the Company's obligations under its pension plans. Based on this review, the Compensation Committee finds the Chief Executive Officer's and the other named executives' total compensation, in the aggregate, to be reasonable and appropriately linked to the Company's performance. The Compensation Committee therefore recommends that stockholders vote "FOR" the say-on-pay proposal included as Proposal 3 in this Proxy Statement.

¹

Section 280G of the Code defines "parachute payments" as payments which (i) are compensatory in nature, (ii) are made to or for the benefit of a stockholder, officer or highly compensated individual and (iii) are contingent on a change in ownership or effective control (or change in ownership of a substantial portion of assets) of a corporation. If the parachute payments have an aggregate present value of at least three times the average annual compensation earned by the recipient of the payment over the five years preceding the date of the change of control, the amount of the payments in excess of one times such average annual compensation are not deductible by the payor for federal income tax purposes and are subject to a 20% excise tax (payable by the recipient) in addition to regular income taxes.

        Option Exercises and Stock Vested Table—This table presents information about stock options exercised by the named executives and the number and value of stock awards that became vested in the named executives during 2018.

        Pension Benefits Table—This table provides the actuarial present value of each named executive's accumulated benefit under the Retirement Plan and the Supplemental Pension Plan.

        The Retirement Plan provides benefits under a cash balance benefit accrual formula. Under the formula, participants accumulate a cash balance benefit based upon compensation credits made annually to the participants' cash balance accounts. The amount of the compensation credits range from 3.0% to 7.5% of total base salary and annual bonus (including amounts deferred under the 401(k) Plan and Section 125 of the Code) depending on each participant's years of service. The cash balance account is further credited with interest annually. The interest credit is based on the One-Year Treasury Constant Maturities as published in the Federal Reserve Statistical Release over the one-year period ending on the December 31^st immediately preceding the applicable plan year. The interest rate for the plan year ending December 31, 2018 was 4.0%. The Retirement Plan was closed to new participants effective December 31, 2004. No employees hired on or after January 1, 2005 are eligible to participate in the Retirement Plan.

        The benefits under the Supplemental Pension Plan are equal to the difference between the benefits that would have been payable under the Retirement Plan without regard to the limitation imposed by the Code on the amount of compensation that may be taken into account under the Retirement Plan or the limitation on participation in the Retirement Plan that became effective on January 1, 2005 and the actual benefits payable under the Retirement Plan as so limited.

Table of Contents

        Benefits under the Retirement Plan are payable as a monthly annuity or in a lump sum payment. Vested benefits under the Supplemental Pension Plan are payable only in the form of a monthly annuity. The benefits under the Retirement Plan become vested after the executive completes five years of vesting service, or, if earlier, the date the executive terminates employment due to death or disability. The benefits under the Supplemental Pension Plan become vested after the executive completes 10 years of vesting service and retires at or after age 55, or, if earlier, the date the executive terminates employment due to death or disability. The Company amended the Supplemental Pension Plan, effective January 1, 2019, to eliminate the age 55 vesting requirement.

        Nonqualified Deferred Compensation Table—This table provides information about contributions and earnings credited to the accounts of the named executive officers under the Company's supplemental 401(k) Plan during 2018. The amounts shown in this table include only deferred salary and annual incentive compensation and do not include deferred performance or restricted Shares.

        The supplemental 401(k) Plan provides covered officers, including the named executive officers, the opportunity to defer compensation that could not be deferred under the tax-qualified 401(k) Plan due to the Code limitations that apply to the 401(k) Plan. The Company provides a matching contribution equal to 100% of the first 4% of base salary and annual incentive compensation deferred under the supplemental 401(k) Plan. Each participant in the supplemental 401(k) Plan may direct the deferrals of base salary or annual incentive compensation and the matching contributions among the different investment options offered by the Company from time to time. The investment options

currently include a fixed rate fund and various stock index funds. All amounts credited to a participant's account under the supplemental 401(k) Plan are 100% vested and will generally be paid in a lump sum or installments in accordance with the participant's election after the participant terminates employment with the Company. In the event the participant dies or becomes disabled while employed by the Company, terminates employment before attaining the age of 60 or within one year after a change of control of the Company, all amounts credited to the participant's account will be distributed in a lump sum in accordance with the terms of the supplemental 401(k) Plan. A participant may also elect to receive one or more in-service distributions.

        Potential Payments Upon Termination or Change of Control—This table shows the amounts that would have been payable to the named executives (other than Messrs. Altmeyer and Ford who both left the employ of the Company before December 31, 2018) under the change of control agreements described on pages 33 through 34 if a change of control of the Company had occurred on December 31, 2018 and the named executives' employment with the Company terminated under the terms of the change of control agreements immediately thereafter. The terms of the Company's equity awards to the named executive officers provide for vesting of outstanding stock options and continued vesting of performance Shares upon retirement at or after attaining age 65 and vesting of restricted Shares upon reaching age 65. None of the named executives have reached age 65.

        The amounts shown in the table below for Messrs. Altmeyer and Ford are the amounts payable to them in connection with their separation from service effective September 12, 2018 (in the case of Mr. Altmeyer) and November 19, 2018 (in the case of Mr. Ford).

        Following termination of employment, the named executive officers receive retirement benefits and nonqualified deferred compensation benefits under the Retirement Plan, the Supplemental Pension Plan and the supplemental 401(k) Plan. The value of those benefits as of December 31, 2018 is set forth in the sections above entitled "Pension Benefits Table" and "Nonqualified Deferred Compensation Table." There are no special or enhanced benefits provided under those plans in connection with a change of control of the Company, except if a named executive officer terminates employment within one year after a change of control, all amounts credited to the named executive officer's account under the supplemental 401(k) Plan will be distributed in a lump sum even if the officer had previously elected to be paid in installments.

        Pay Ratio Disclosure—The SEC rules require the Company to disclose annually (i) the median of the annual total compensation of all employees of the Company (excluding D. Christian Koch, the Company's principal executive officer); (ii) the annual total compensation of Mr. Koch; and (iii) the ratio of Mr. Koch's annual total compensation to the median annual total compensation of all other employees.

47

---

Table of Contents

        Based on the methodology and material assumptions described below, the Company has estimated these amounts to be as follows:

        For 2018, the Company used the same median employee selected in 2017 to determine the median annual total compensation of all employees (excluding Mr. Koch). To determine the median employee in 2017, the Company compiled a list of all employees (excluding Mr. Koch) as of October 2, 2017, sorted the list of employees by their annualized gross compensation rates as of October 2, 2017 and selected the employee with the median annualized gross compensation amount. The Company did not include in the compensation rates the value of Company-provided benefits such as retirement and medical and life insurance benefits. As of October 2, 2017, the Company employed 14,181 persons, of which 7,698 employees were employed in foreign countries. The compensation of employees in foreign countries was converted to an equivalent U.S. dollar amount using foreign exchange rates on October 2, 2017. During 2018, the Company added approximately 500 new employees from its acquisition of Accella Holdings LLC and decreased employment by approximately 920 employees upon the sale of Carlisle Foodservice Products, Inc. Based on demographic analysis, the Company reasonably believes that Accella Holdings LLC and Carlisle Foodservice Products, Inc. have, in the aggregate, similar pay demographics and that such change in employee population during 2018 did not significantly affect the Company's pay ratio disclosure for 2018.

        The annual total compensation of Mr. Koch is the total amount of his compensation presented in the Summary Compensation Table on page 35. The Company calculated the annual total compensation of the median employee using the same rules applicable to the completion of the Summary Compensation Table for Mr. Koch and the other named executives.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

        Section 16(a) of the Exchange Act requires the Company's executive officers and directors and persons who beneficially own more than 10% of any class of the Company's equity securities (collectively, the "reporting persons") to file with the SEC initial reports of their beneficial ownership of the Company's equity securities and reports of changes in their beneficial ownership of the Company's equity securities. Based solely on a review of such reports and written representations made by the Company's executive officers and directors with respect to the completeness and timeliness of their filings, the Company believes that the reporting persons complied with all applicable Section 16(a) filing requirements on a timely basis during fiscal 2018.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

        Robin J. Adams, Robert G. Bohn, Terry D. Growcock (until his retirement on May 2, 2018), Gregg A. Ostrander, Corrine D. Ricard and Jesse G. Singh served on the Compensation Committee in fiscal 2018. None of the directors who served on the Compensation Committee in fiscal 2018 has ever served as one of the Company's officers or employees or had any relationship with the Company or any of its subsidiaries since the beginning of fiscal 2018 pursuant to which disclosure would be required under the SEC rules pertaining to the disclosure of transactions with related persons. During fiscal 2018, none of the Company's executive officers served as a director or member of the compensation committee (or other committee performing equivalent functions) of any other entity of which an executive officer of such other entity served on the Board or its Compensation Committee.

COMPENSATION COMMITTEE REPORT

        The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis included in this Proxy Statement with management and, based on such review and discussions, recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement and in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

REPORT OF THE AUDIT COMMITTEE

        The Audit Committee is comprised of six non-employee directors. The Board has made a determination that the members of the Audit Committee satisfy the requirements of the NYSE as to independence, financial literacy and experience. The responsibilities of the Audit Committee are set forth in the Charter of the Audit Committee, which is reviewed annually by the committee.

        The Audit Committee has the sole authority to appoint and terminate the engagement of the Company's independent registered public accounting firm. The Audit Committee also reviews the arrangements for and the results of the independent registered public accounting firm's examination of the Company's books and records, internal accounting control procedures, the activities and recommendations of the Company's internal auditors, and the Company's accounting policies, control systems and compliance activities. The Board has determined that Robin J. Adams, James D. Frias and Lawrence A. Sala are "audit committee financial experts" as defined by the SEC rules. Below is a report on the Audit Committee's activities relating to fiscal 2018.

Review of Audited Consolidated Financial Statements with Management

        The Audit Committee has reviewed and discussed with management the audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

Review of Audited Consolidated Financial Statements and Other Matters with Independent Registered Public Accounting Firm

        The Audit Committee has discussed with the Company's independent registered public accounting firm the audited consolidated financial statements and the matters required to be discussed by Auditing Standard No. 1301, "Communications with Audit Committees," as adopted by the Public Company Accounting Oversight Board (the "PCAOB"). The Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm its independence. In concluding that such firm is independent, the Audit Committee considered, among other factors, whether the non-audit services provided by such firm were compatible with its independence. See "Fees Paid to Independent Registered Public Accounting Firm" below.

Recommendation that Audited Consolidated Financial Statements be Included in Annual Report

        Based on the reviews, discussions and disclosures referred to above, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements of the Company for the fiscal year ended December 31, 2018 be included in the Company's Annual Report on Form 10-K for such fiscal year.

PROPOSAL 2:
RATIFICATION OF THE APPOINTMENT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

        The Audit Committee of the Board of Directors has appointed Deloitte & Touche LLP to serve as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2019. Deloitte & Touche LLP has acted in such capacity for the Company since May 16, 2017, the effective date of the Audit Committee's approval of the engagement of Deloitte & Touche LLP as the Company's independent registered public accounting firm for the fiscal year ended December 31, 2017 and the dismissal of Ernst & Young LLP from that role.

        The reports of Ernst & Young LLP on the Company's consolidated financial statements as of and for the fiscal years ended December 31, 2015 and 2016 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the fiscal years ended December 31, 2015 and 2016, and the subsequent interim period through May 16, 2017, there were no (i) "disagreements" (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K) with Ernst & Young LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to Ernst & Young LLP's satisfaction, would have caused Ernst & Young LLP to make reference to the subject matter thereof in its reports for such fiscal years and interim period, or (ii) "reportable events" (as that term is described in Item 304(a)(1)(v) of Regulation S-K).

        The Company expects that representatives of Deloitte & Touche LLP will be present at the Annual Meeting, and the representatives will have an opportunity to make a statement if they desire to do so. The Company also expects that representatives will be available to respond to appropriate questions from stockholders.

        Stockholder ratification of the Audit Committee's appointment of Deloitte & Touche LLP to serve as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2019 is not required by the Company's Amended and Restated Bylaws or otherwise. Nevertheless, the Board is submitting the appointment of Deloitte & Touche LLP to the Company's stockholders for ratification as a matter of good corporate governance. If the Company's stockholders fail to ratify the appointment, the Audit Committee will reconsider its appointment of Deloitte & Touche LLP. Even if this appointment is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the fiscal year if the Audit Committee determines that such a change would be in the best interests of the Company and its stockholders.

        The Board of Directors recommends that you vote "FOR" the ratification of the appointment of Deloitte & Touche LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2019. Unless otherwise specified, proxies will be voted "FOR" the ratification of the appointment of Deloitte & Touche LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2019.

A.  Fees Paid to Independent Registered Public Accounting Firm

        The following table presents fees for professional audit services rendered by Deloitte & Touche LLP for the audit of the Company's consolidated financial statements for the fiscal years ended December 31, 2018 and 2017 and fees billed for other services rendered by Deloitte & Touche LLP during those periods:

B.  Audit Committee Pre-Approval of Audit and Non-Audit Services

        All audit and permissible non-audit services to be performed by the Company's independent registered public accounting firm are subject to a pre-approval requirement of the Audit Committee. These services may include audit services, audit-related services, tax services and other services. All such services provided in fiscal 2018 were pre-approved by the Audit Committee. The Audit Committee concluded that the provision of such services by Deloitte & Touche LLP was compatible with the maintenance of that firm's independence. The Audit Committee has delegated to the Chairman of the Audit Committee pre-approval authority with respect to certain permissible non-audit services. The Chairman's pre-approval authority is limited to engagements costing no more than $200,000 in the aggregate and any such engagements approved by the Chairman shall be presented to the full Audit Committee at its next regularly scheduled meeting.

PROPOSAL 3:
ADVISORY VOTE TO APPROVE
NAMED EXECUTIVE OFFICER COMPENSATION

        As required by Section 14A of the Exchange Act, this proposal, commonly known as a "say-on-pay" proposal, gives the Company's stockholders the opportunity to vote to approve or not approve, on an advisory basis, the compensation of the Company's named executive officers, which is described in the "Compensation Discussion and Analysis" section of this Proxy Statement. This vote is not intended to address any specific item or element of compensation or the compensation of any particular officer, but rather the overall compensation of the Company's named executive officers and the philosophy, principles and policies used to determine compensation.

        Stockholders were most recently asked to approve the compensation of the Company's named executive officers at the Company's 2018 Annual Meeting of Stockholders, and stockholders approved the Company's named executive officer compensation with approximately 95% of the votes cast in favor. At the Company's 2017 Annual Meeting of Stockholders, stockholders were asked to indicate whether future advisory say-on-pay votes should occur every one, two or three years, with the Board recommending an annual advisory vote. Because the Board views it as a good corporate governance practice, and because at the 2017 Annual Meeting of Stockholders a majority of the votes cast were in favor of an annual advisory vote, the Board adopted a policy that the Company will include an advisory say-on-pay vote in the Company's proxy materials on an annual basis until the next required advisory stockholder vote on the frequency of advisory stockholder votes on named executive officer compensation, which will occur no later than the Company's annual meeting of stockholders in 2023.

        The compensation program for the Company's named executive officers is based on the following guiding principles:

•

Provide competitive total direct compensation opportunity;



•

Reward performance that is consistent with key strategic and stockholder goals;



•

Balance performance measures and, where appropriate, emphasize overall corporate, operating business and division performance;



•

Serve as a retention tool for key executive talent, provide a balance of liquidity and reward executives for superior performance; and



•

Be transparent, simple to administer and easy to communicate.

Stockholders are urged to read the "Compensation Discussion and Analysis" section of this Proxy Statement, which provides a thorough description of how the Compensation Committee has designed and administered the executive compensation program to comply with these principles.

        At the Annual Meeting, the Company's stockholders will have the opportunity to endorse or not endorse the compensation of the named executive officers through a non-binding vote on the following resolution:

RESOLVED, that the compensation paid to the Company's named executive officers, as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis, the compensation tables and the related narrative discussion, is hereby approved.

        This vote is advisory, which means that the stockholder vote on this proposal will not be binding on the Company, the Compensation Committee or the Board, nor will it create or imply any change in the fiduciary duties of, or impose any additional fiduciary duty on, the Company, the Compensation Committee or the Board. However, the Compensation Committee and the Board value the opinions of

Any such stockholder proposal must also comply with Rule 14a-8 of the Exchange Act, which lists the requirements for the inclusion of stockholder proposals in company-sponsored proxy materials. Stockholder proposals should be addressed to the attention of the Company's Secretary at Carlisle Companies Incorporated, 16430 North Scottsdale Road, Suite 400, Scottsdale, Arizona 85254. Pursuant to the SEC rules, submitting a proposal will not guarantee that it will be included in the Company's proxy materials.

        In addition, any stockholder proposal (other than nominations for directors) intended to be presented at the 2020 Annual Meeting of Stockholders, but that will not be included in the Company's proxy statement and form of proxy relating to the 2020 Annual Meeting of Stockholders, must be received by the Company's Secretary at Carlisle Companies Incorporated, 16430 North Scottsdale Road, Suite 400, Scottsdale, Arizona 85254, either in person or by U.S. certified mail, postage prepaid, not later than the close of business on the 90^th day nor earlier than the close of business on the 120^th day prior to the first anniversary of the Annual Meeting. As a result, any proposals submitted by a stockholder pursuant to the provisions of the Company's Amended and Restated Bylaws (other than proposals submitted pursuant to Rule 14a-8 or nominations for directors) must be received no earlier than January 9, 2020 and no later than February 8, 2020. However, in the event that the date of the 2020 Annual Meeting of Stockholders is more than 30 days before or more than 60 days after May 8, 2020, notice by the stockholder to be timely must be so delivered or received not earlier than the close of business on the 120^th day prior to the date of the 2020 Annual Meeting of Stockholders and not later than the close of business on the later of the 90^th day prior to such annual meeting or the 10^th day following the day on which public announcement of the date of such meeting is first made by the Company.

Incorporated, 16430 North Scottsdale Road, Suite 400, Scottsdale, Arizona 85254; (ii) delivering a proxy bearing a later date via the Internet, by telephone or by mail until the applicable deadline for each method; or (iii) attending the Annual Meeting and voting in person. Attendance at the Annual Meeting will not cause your previously granted proxy to be revoked unless you specifically make that request or vote in person at the meeting. For all methods of voting, the last vote cast will supersede all previous votes. If you hold your Shares in street name and you have instructed your bank, broker or other nominee to vote your Shares, you may revoke or change your voting instructions by following the specific instructions provided to you by your bank, broker or other nominee, or, if you have obtained a legal proxy from your bank, broker or other nominee, by attending the Annual Meeting and voting in person.

        The number of votes that each stockholder will be entitled to cast at the Annual Meeting will depend on when the Shares were acquired and whether or not there has been a change in beneficial ownership since the date of acquisition, with respect to each of such holder's Shares.

        Stockholders whose Shares are held by banks or brokers or in nominee name are requested to confirm to the Company how many of the Shares they owned as of March 13, 2019 were beneficially owned before March 13, 2015, entitling such stockholder to five votes per Share, and how many were acquired after March 12, 2015, entitling such stockholder to one vote per Share. If no confirmation of beneficial ownership is received from a stockholder prior to the Annual Meeting, it will be deemed by the Company that beneficial ownership of all such Shares was effected after March 12, 2015, and the stockholder will be entitled to one vote for each Share. If a stockholder provides incorrect information, he or she may provide correct information at any time prior to the voting of his or her Shares at the Annual Meeting.

        The Notice of Internet Availability of Proxy Materials, or a printed copy of the proxy materials (including this Proxy Statement and form of proxy), as applicable, are being furnished to stockholders of record on March 13, 2019 whose Shares on the records of the Company show the following:

          (i)  that such stockholder had beneficial ownership of such Shares before March 13, 2015, and there has been no change since that date, thus entitling such stockholder to five votes for each Share; or

         (ii)  that beneficial ownership of such Shares was effected after March 12, 2015, thus entitling such stockholder to one vote for each Share; or

        (iii)  that the dates on which beneficial ownership of such Shares were effected are such that such stockholder is entitled to five votes for some Shares and one vote for other Shares.

        Printed on the Notice of Internet Availability of Proxy Materials (or proxy card if you received or request one) for each individual stockholder of record is the number of Shares for which he or she is entitled to cast five votes each and/or one vote each, as the case may be, as shown on the records of the Company.

        Stockholders of record are urged to review the number of Shares shown on their Notice of Internet Availability of Proxy Materials (or proxy card if they received or request one) in the five-vote and one-vote categories. If the number of Shares shown in a voting category is believed to be incorrect, the stockholder should notify the Company in writing of that fact and either mail the notice directly to the Company at the address indicated above or enclose the notice along with the proxy card (if the stockholder received or requests one) in the postage-paid envelope provided. The stockholder should identify the Shares improperly classified for voting purposes and provide information as to the date beneficial ownership was acquired. Any notification of improper classification of votes must be made at least three business days prior to the Annual Meeting or the stockholder will be entitled at the Annual Meeting to the number of votes indicated on the records of the Company.

        In certain cases record ownership may change but beneficial ownership for voting purposes does not change. The Restated Certificate of Incorporation of the Company states the exceptions where beneficial ownership is deemed not to have changed upon the transfer of Shares. Stockholders should consult the pertinent provision of the Restated Certificate of Incorporation attached as Appendix A to this Proxy Statement for those exceptions.

        By resolution duly adopted by the Board of Directors of the Company pursuant to subparagraph B of Article FOURTH of the Restated Certificate of Incorporation, the following procedures have been adopted for use in determining the number of votes to which a stockholder is entitled:

          (i)  The Company may accept the written and signed statement of a stockholder to the effect that no change in beneficial ownership has occurred during the four years immediately preceding the date on which a determination is made of the stockholders of the Company who are entitled to vote or take any other action. Such statement may be abbreviated to state only the number of Shares as to which such stockholder is entitled to exercise five votes or one vote.

         (ii)  In the event the Vice President, Treasurer of the Company, in his or her sole discretion, taking into account the standards set forth in the Company's Restated Certificate of Incorporation, deems any such statement to be inadequate or for any reason deems it in the best interest of the Company to require further evidence of the absence of change of beneficial ownership during the four-year period preceding the record date, he or she may require such additional evidence and, until it is provided in form and substance satisfactory to him or her, a change in beneficial ownership during such period shall be deemed to have taken place.

        (iii)  Information supplementing that contemplated by paragraph (i) and additional evidence contemplated by paragraph (ii) may be provided by a stockholder at any time but must be furnished at least three business days prior to any meeting of stockholders at which such Shares are to be voted for any change to be effective at such meeting.

HOUSEHOLDING

        The SEC has adopted rules permitting companies to mail one proxy statement and annual report, or notice of internet availability of proxy materials, as applicable, in one envelope to all stockholders residing at the same address if certain conditions are met. This is called "householding" and can result in significant savings of paper and mailing costs. The Company has not implemented householding with respect to its stockholders of record; however, a number of brokerage firms have instituted householding that may impact certain beneficial owners of Shares held in street name. If members of your household have multiple accounts through which they hold Shares, you may have received a householding notification from your bank, broker or other nominee.

        Please contact your bank, broker or other nominee directly if you have any questions or wish to revoke your decision to household or to receive an additional copy of this Proxy Statement, the 2018 Annual Report to Stockholders or the Notice of Internet Availability of Proxy Materials for members of your household.
