EXPLANATORY NOTE

MuleSoft, Inc. (the Company, we, us, or our) is filing this Amendment No. 1 on Form 10-K/A (this Amendment No. 1) to amend our Annual Report on Form 10-K for the year ended December 31, 2017, originally filed with the Securities and
Exchange Commission (the SEC) on February 22, 2018 (the Original Form 10-K), to include the information required by Items 10 through 14 of Part III of Form 10-K. This information was previously omitted from the Original Form 10-K in reliance on General Instruction G(3) to Form 10-K, which
permits the information in the above referenced items to be incorporated in the Form 10-K by reference from our definitive proxy statement if such statement is filed no later than 120 days after our fiscal year-end. We are filing this Amendment No. 1 to provide the information required in Part III of Form 10-K because a definitive proxy statement containing such
information may not be filed by the Company within 120 days after the end of the fiscal year covered by the Form 10-K.

Pursuant to the rules of the SEC, Part IV, Item 15 has also been amended to contain the currently dated certifications from the
Companys principal executive officer and principal financial officer pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. The certifications of the Companys principal executive officer and principal financial officer are
attached to this Amendment No. 1 as Exhibits 31.3 and 31.4. Because no financial statements have been included in this Amendment No. 1 and this Amendment No. 1 does not contain or amend any disclosure with respect to Items 307 and 308
of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. We are not including the certificate under Section 906 of the Sarbanes-Oxley Act of 2002 as no financial statements
are being filed with this Amendment No. 1. Part IV, Item 15 has also been amended to include certain exhibits required to be filed as part of this Amendment No. 1.

Except as described above, this Amendment No. 1 does not modify or update disclosure in, or exhibits to, the Original Form 10-K. Furthermore, this Amendment No. 1 does not change any previously reported financial results, nor does it reflect events occurring after the filing date of the Original
10-K. Information not affected by this Amendment No. 1 remains unchanged and reflects the disclosures made at the time the Original 10-K was filed. This Amendment
No. 1 should be read in conjunction with the Original Form 10-K and with our filings with the SEC subsequent to the Original Form 10-K.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934, as amended (the Exchange Act) requires that our executive officers,
directors and 10% stockholders file reports of ownership and changes of ownership with the SEC. Such directors, executive officers and 10% holders of our common stock are required by SEC regulation to furnish us with copies of all Section 16(a)
forms they file.

SEC regulations require us to identify in this proxy statement anyone who filed a required report late during the most
recent fiscal year. Based on our review of forms we received, or written representations of our executive officers, directors and 10% holders, we believe that during our fiscal year ended December 31, 2017, all Section 16(a) filing
requirements were satisfied on a timely basis except for a Form 3 filed by Bain Capital Public Equity Management, LLC, Brookside Capital Partners Fund, L.P. and Brookside Capital Trading Fund, L.P. (collectively the Bain Capital Joint
Filers) with the SEC on March 30, 2017, as amended on March 31, 2017 and a Form 4 for the Bain Capital Joint Filers filed with the SEC on March 30, 2017, as amended on March 31, 2017.

Corporate Governance Guidelines and Code of Business Conduct and Ethics

Our board of directors has adopted corporate governance guidelines that address items such as the qualifications and responsibilities of our
directors and director candidates and corporate governance policies and standards applicable to us in general. In addition, our board of directors has adopted a code of business conduct and ethics that applies to all of our employees, officers and
directors, including our Chief Executive Officer, Chief Financial Officer, and other executive and senior financial officers. The full text of our corporate governance guidelines and our code of business conduct and ethics is posted on the
Governance portion of our website at http://investors.mulesoft.com. We will post amendments to our code of business conduct and ethics or waivers of our code of business conduct and ethics for directors and executive officers on the same website.

Board of Directors

Our business and affairs are managed under the direction of our board of directors. The number of directors is fixed by our board of directors,
subject to the terms of our amended and restated certificate of incorporation and amended and restated bylaws. Our board of directors consists of nine directors, eight of whom qualify as independent under the New York Stock Exchange
listing standards.

In accordance with our amended and restated certificate of incorporation and our amended and restated bylaws, our
board of directors is divided into three classes with staggered three-year terms. Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective
three-year terms. Our directors are divided among the three classes as follows:



| |  |  | the Class I directors are Messrs. Little, Ryu and Schott and Ms. Winblad, and their terms expire at the annual meeting of stockholders to be held in 2018;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | the Class II directors are Messrs. Capellas and Mhatre and Ms. Wassenaar, and their terms expire at the annual meeting of stockholders to be held in 2019; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the Class III directors are Messrs. Burton and Collins, and their terms expire at the annual meeting of stockholders to be held in 2020.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------

Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class
will consist of one-third of the directors. This classification of our board of directors may have the effect of delaying or preventing changes in control of our company.

Director Independence

Our Class A common stock is listed on the New York Stock Exchange. Under the listing standards of the New York Stock Exchange, independent
directors must comprise a majority of a listed companys Board of Directors. In addition, the listing standards of the New York Stock Exchange require that, subject to specified exceptions, each member of a listed companys audit,
compensation, and nominating and corporate governance committees be independent. Under the listing standards of the New York Stock Exchange, a director will only qualify as an independent director if, in the opinion of that listed
companys board of directors, that director does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Audit committee members must also satisfy the additional independence criteria set forth in
Rule 10A-3 under the Exchange Act, and the listing standards of the New York Stock Exchange. Compensation committee members must also satisfy the additional independence criteria set forth in Rule 10C-1 under the Exchange Act and the listing standards of the New York Stock Exchange.

Our
board of directors has undertaken a review of the independence of each of our directors. Based on information provided by each director concerning his or her background, employment and affiliations, our board of directors has determined that Messrs.
Burton, Capellas, Collins, Little, Mhatre and Ryu and Mses. Wassenaar and Winblad do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these
directors is independent as that term is defined under the listing standards of the New York Stock Exchange. In making these determinations, our board of directors considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by
each non-employee director, and the transactions involving them described in the section titled Related Person Transactions.

Board Leadership Structure

Greg Schott currently serves as both Chairman of our board of directors and as our Chief Executive Officer. Our independent directors bring
experience, oversight and expertise from outside of our Company, while Mr. Schott brings company-specific experience and expertise. We believe that the structure of our board of directors and its committees provides effective independent
oversight of management while Mr. Schotts combined role enables strong leadership, creates clear accountability and enhances our ability to communicate our message and strategy clearly and consistently to stockholders.

Lead Independent Director

Our board of directors has adopted corporate governance guidelines that provide that one of our independent directors should serve as our Lead
Independent Director at any time when our Chief Executive Officer serves as the Chairman of our board of directors or if the Chairman is not otherwise independent. Because Mr. Schott is our Chairman and is not an independent
director as defined in the listing standards of the New York Stock Exchange, our Board of Directors has appointed Michael Capellas to serve as our Lead Independent Director. As Lead Independent Director, Mr. Capellas presides over periodic
meetings of our independent directors, serve as a liaison between our Chairman and our independent directors and perform such additional duties as our board of directors may otherwise determine and delegate.

Board Meetings and Committees

During our fiscal year ended December 31, 2017, the board of directors held eight meetings (including regularly scheduled and special
meetings), and each director attended at least 75% of the aggregate of (i) the total number of meetings of our board of directors held during the period for which he or she has been a director and (ii) the total number of meetings held by
all committees of our board of directors on which he or she served during the periods that he or she served.

We encourage, but do not
require, members of our board of directors to attend our annual meetings of stockholders.

Our board of directors has established an audit
committee, a compensation committee and a nominating and corporate governance committee. The composition and responsibilities of each of the committees of our board of directors is described below. Members will serve on these committees until their
resignation or until otherwise determined by our board of directors.

Each member of our audit committee also meets the financial literacy and sophistication requirements of the listing standards of the New York Stock Exchange. In addition, our board of directors has determined that Mr. Collins is an audit
committee financial expert within the meaning of Item 407(d) of Regulation S-K under the Securities Act of 1933, as amended (the Securities Act) and satisfies the financial expertise
requirements under the listing standards of the New York Stock Exchange. Our audit committee is, among other things, responsible for the following:

Rule 16b-3 promulgated under the Exchange Act, and an outside director, as defined pursuant to Section 162(m) of the Internal Revenue Code (the Code). Our compensation committee is, among
other things, responsible for the following:

Director Compensation

In connection with our initial public offering in 2017, our board of directors adopted our Outside Director Compensation Policy. Members of the
board of directors who are not our employees are eligible to receive compensation under our Outside Director Compensation Policy. Our Outside Director Compensation Policy became effective on March 16, 2017. The Outside Director Compensation
Policy is summarized below.

Equity Compensation



| |  |  | Initial Award.Each person who first becomes a non-employee
director after March 16, 2017 and following the first annual meeting of our stockholders, or annual meeting, will be granted a restricted stock unit award, or the Initial Award, which grant will be effective on the date on which
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| | such individual first becomes a non-employee director, whether through election by our stockholders or appointment by our board of directors to fill a
vacancy, having a value (as described below) of $175,000 multiplied by a fraction, the numerator of which is (a) 12 minus (b) the number of full months between the date of our last annual meeting and the date the individual becomes a non-employee director, and the denominator of which is 12 (with the result rounded down to the nearest whole share). A director who is an employee who ceases to be an employee, but who remains as a director, will
not receive an Initial Award.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Annual RSU Award.On the date of each annual meeting beginning with the first annual meeting following March 16, 2017, each non-employee director automatically will be
granted a restricted stock unit award having a value (as described below) equal to $175,000 (rounded down to the nearest whole share), or the Annual Award; provided that any non-employee director who is not
continuing as a director following the applicable annual meeting will not receive an Annual Award with respect to such annual meeting.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Notwithstanding the foregoing, for each non-employee director who holds equity awards granted prior to
March 16, 2017, or Pre-IPO Awards, that remain unvested on the annual meeting date, the value of the Annual Award granted to such non-employee director with respect
to the annual meeting will be calculated by subtracting the Pre-IPO Award Value from $175,000. If the Pre-IPO Award Value is equal to or greater than $175,000, the non-employee director will not receive an Annual Award with respect to such annual meeting. For purposes of our Outside Director Compensation Policy, Pre-IPO Award Value means
the intrinsic value of shares subject to a Pre-IPO Award that are scheduled to vest during the 12-month period following the date of the annual meeting at which the
Annual Award is to be granted, or the Vesting Shares, with such intrinsic value equal to the difference between the value of the Vesting Shares less the applicable exercise price of the Vesting Shares, if any. The value of the Vesting Shares will
equal the average fair market value (as defined in our 2017 Equity Incentive Plan (the 2017 Plan)) of one share of our Class A common stock for market trading days that occur in the completed calendar month immediately prior to the
calendar month in which the annual meeting occurs.



| |  |  | For purposes of our Outside Director Compensation Policy, value will equal the product of (i) the average fair market value of one share of our Class A common stock for the market trading days that occur in

Potential Payments Upon Termination or Upon Termination or Change in Control

In January 2017, we adopted a Severance Policy applicable to our named executive officers and certain other key employees that superseded all
previous severance arrangements we had entered into with these eligible employees prior to the Severance Policy becoming effective (except that the individuals equity awards will continue to be governed by the terms of the applicable equity
agreements and plan documents, including any accelerated vesting provisions). Under our Severance Policy, if any eligible employee, including our named executive officers, is terminated by us other than for cause, as defined in the Severance Policy,
death or disability, as defined in the Severance Policy, or if the eligible employee terminates his or her employment with us due to a constructive termination, as defined in the Severance Policy, the eligible employee will be entitled to receive
severance benefits as exclusively provided for under the Severance Policy. Upon the occurrence of such an event, an eligible employee would be entitled to the following if such eligible employee timely signs and does not revoke a separation
agreement and release of claims: (i) a lump-sum cash severance payment equal to the eligible employees rate of pay multiplied by a severance multiple, and (ii) a
lump-sum cash payment equal to $1,000 (which will be paid regardless of whether the eligible employee elects COBRA continuation coverage and can be used for any purpose by the eligible employee). The rate of
pay for an eligible employee equals the value of one-week of the eligible employees base salary. The severance multiple equals four plus the eligible employees length of service. For purposes of
the Severance Policy, length of service means the eligible employees number of completed years of continuous service with us beginning with the eligible employees most recent hire date through the date of the qualifying termination, with
any partial year of service rounded up to the next full year of service. In the event any of the amounts provided for under the Severance Policy or otherwise payable to an eligible employee would constitute a parachute payment within the
meaning of Section 280G of the Code and could be subject to the related excise tax, the eligible employee would be entitled to receive either full payment of benefits or such lesser amount which would result in no portion of the benefits being
subject to the excise tax, whichever results in the greater amount of after-tax benefits to the eligible employee.

In addition, each of our named executive officers equity awards continues to be governed by the terms of the applicable equity
agreements and plan documents, including any accelerated vesting provisions, except to the extent amended by the letter agreements entered into by the named executive officers described below.

In the event that there is a change of control, as defined in each named executive officers award agreement, and on or within 12 months following the date of such change of control,
either the named executive officers employment is terminated without cause, as defined in the award agreement, or the named executive officer resigns for his employment with good reason, as defined in the award agreement, and provided the
named executive officer executes a general release at the time of his termination of employment, then vesting with respect to 50% of the unvested shares subject to each award will accelerate and become vested upon such termination.

For purposes of our equity award agreements with our named executive officers, cause means generally:



| |  |  | continued refusal or failure to perform duties reasonably expected of the executive in connection with his arrangement to provide services to us or any parent, subsidiary, or successor, as applicable (provided that the
executive is given 10 days written notice and opportunity to cure);
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | unprofessional, unethical, or fraudulent conduct or conduct that discredits us or any parent, subsidiary, or successor, as applicable, or is detrimental to our or any parents, subsidiarys, or
successors, as applicable, reputation, character, or standing;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | dishonest conduct, or a deliberate attempt to do any injury to us or any parent, subsidiary, or successor, as applicable;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | a material breach of any employment agreement between the executive and us or any parent, subsidiary, or successor, as applicable; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a criminal act which would reflect badly on us or any parent, subsidiary, or successor, as applicable.
| | - |  | ------------------------------------------------------------------------------------------------------

Effective March 20, 2018, each of our executive officers, including our named executive officers, entered into a letter agreement, or a
Letter Agreement, with us. Pursuant to the terms of each Letter Agreement, effective as of immediately prior to the completion of a merger involving the Company that constitutes a change of control of the Company under the terms of the
individuals respective equity award agreements, our named executive officers each agreed to waive, and acknowledged that they would not have the right to assert Good Reason under the terms of any equity award agreement with us as a
result of any changes to their duties, position, authority or responsibilities or the removal from such position and responsibilities. As consideration for entering into the Letter Agreement, the equity awards held by each of our named executive
officers were amended to provide that the number of unvested shares subject to an equity award that would vest upon a qualifying termination of employment in connection with a change of control would increase from 50% to 100%. The accelerated
vesting percentage applicable to Mr. Schotts equity awards in the event of a qualifying termination of employment in connection with a change of control did not change.

401(k) Plan

We maintain a tax-qualified retirement plan, or the 401(k) plan, that provides eligible employees with
an opportunity to save for retirement on a tax-advantaged basis. Eligible employees are able to participate in the 401(k) plan as of the first day of the month following the date they meet the 401(k)
plans eligibility

requirements, and participants are able to defer up to 85% of their eligible compensation subject to applicable annual Code limits. All participants interests in their deferrals are 100%
vested when contributed. The 401(k) plan permits us to make matching contributions and profit sharing contributions to eligible participants, although we have not made any such contributions to date.

##### Table of Contents

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth certain information with respect to the beneficial ownership of our capital stock as of March 28, 2018 for:



| |  |  | each person or group of affiliated persons known by us to be the beneficial owner of more than 5% of our Class A common stock or Class B common stock;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



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



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



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

We have determined beneficial
ownership in accordance with the rules of the SEC, and thus it represents sole or shared voting or investment power with respect to our securities. Unless otherwise indicated below, to our knowledge, the persons and entities named in the table have
sole voting and sole investment power with respect to all shares that they beneficially owned, subject to community property laws where applicable. The information does not necessarily indicate beneficial ownership for any other purpose, including
for purposes of Sections 13(d) and 13(g) of the Securities Act.

Applicable percentage ownership is based on 94,416,981 shares of our
Class A common stock and 39,145,184 shares of our Class B common stock outstanding as of March 28, 2018. In computing the number of shares of capital stock beneficially owned by a person and the percentage ownership of such person, we
deemed to be outstanding all shares of our capital stock subject to options held by the person that are currently exercisable or exercisable within 60 days of March 28, 2018. However, we did not deem such shares of our capital stock outstanding
for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated, the address of each beneficial
owner listed in the table below is c/o MuleSoft, Inc., 77 Geary Street, Suite 400, San Francisco, California 94108.

|Item 13. | Certain Relationships and Related Transactions, and Director Independence
|-------- | -------------------------------------------------------------------------

We describe
below transactions and series of similar transactions, since the beginning of our last fiscal year, to which we were a party or will be a party, in which:



| |  |  | the amounts involved exceeded or will exceed $120,000; and
| | - |  | ----------------------------------------------------------



| |  |  | any of our directors, nominees for director, executive officers or holders of more than 5% of our outstanding capital stock, or any immediate family member of, or person sharing the household with, any of these
individuals or entities, had or will have a direct or indirect material interest.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Investors Rights
Agreement

We are party to an investors rights agreement which provides, among other things, that certain holders of our capital
stock, including entities affiliated with Bay Partners, entities affiliated with Hummer Winblad Venture Partners, entities affiliated with Lightspeed Venture Partners, Morgenthaler Partners VIII, L.P., entities affiliated with New Enterprise
Associates and Sapphire Ventures Fund I, L.P., have the right to demand that we file a registration statement or request that their shares of our capital stock be covered by a registration statement that we are otherwise filing.

Service Arrangements

Ross Mason is employed by us as our Vice President, Product Strategy. He earned $259,250 in annual salary and other cash compensation during
2017. He also received benefits consistent with other employees serving in a similar capacity.

During 2017, we incurred $1,485,454 of
expense for professional services, technical support services and other technical services provided on our behalf by Ricston Ltd. and Ricston UK Ltd. Ross Mason has a 30% equity ownership in Ricston Ltd.

During 2017, we paid $167,500 for an application delivery platform provided by NGINX, Inc. and sponsorship of NGINX, Inc.s conference.
Entities affiliated with New Enterprise Associates own greater than 5% equity ownership in NGINX, Inc.

During 2017, we paid $426,605 for
purchases of software subscriptions to New Relic, Inc. (New Relic), a vendor of the Company. Ms. Wassenaar is the former Chief Information Officer of New Relic.

During 2017, we received payments of $378,709 from Guidewire Software, Inc. (Guidewire) in connection with the purchases of
software subscriptions to the Companys Anypoint Platform. Mr. Ryu is the Chief Executive Officer of Guidewire.

Other Agreements

In addition to the indemnification required in our amended and restated certificate of incorporation and amended and restated bylaws, we have
entered into an indemnification agreement with each member of our board of directors and each of our officers. These agreements provide for the indemnification of our directors

and officers for certain expenses and liabilities incurred in connection with any action, suit, proceeding or alternative dispute resolution mechanism, or hearing, inquiry or investigation that
may lead to the foregoing, to which they are a party, or are threatened to be made a party, by reason of the fact that they are or were a director, officer, employee, agent or fiduciary of our company, or any of our subsidiaries, by reason of any
action or inaction by them while serving as an officer, director, agent or fiduciary, or by reason of the fact that they were serving at our request as a director, officer, employee, agent or fiduciary of another entity. In the case of an action or
proceeding by or in the right of our company or any of our subsidiaries, no indemnification will be provided for any claim where a court determines that the indemnified party is prohibited from receiving indemnification. We believe that these
charter and bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers.

We have entered into employment agreements with certain of our executive officers that, among other things, provide for certain severance and
change of control benefits. For a description of employment agreements with our named executive officers, see Executive CompensationExecutive Employment Agreements.

We have granted stock options to our named executive officers, other executive officers and certain of our directors. See Executive
CompensationExecutive Employment Agreements.

Other than as described above, since January 1, 2017, we have not entered
into any transactions, nor are there any currently proposed transactions, between us and a related party where the amount involved exceeds, or would exceed, $120,000, and in which any related person had or will have a direct or indirect material
interest. We believe the terms of the transactions described above were comparable to terms we could have obtained in arms-length dealings with unrelated third parties.

Policies and Procedures for Related Party Transactions

Our board of directors has adopted a formal written policy providing that our audit committee will be responsible for reviewing related
party transactions, which are transactions, arrangements or relationships (or any series of similar transactions, arrangements or relationships), to which we are a party, in which the aggregate amount involved exceeds or may be expected to
exceed $120,000 and in which a related person has, had or will have a direct or indirect material interest. For purposes of this policy, a related person is defined as a director, executive officer, nominee for director or greater than 5% beneficial
owner of our capital stock, in each case since the beginning of the most recently completed year, and any of their immediate family members. In determining whether to approve or ratify any such transaction, our audit committee will take into
account, among other factors it deems appropriate, (i) whether the transaction is on terms no less favorable than terms generally available to unaffiliated third parties under the same or similar circumstances and (ii) the extent of the
related partys interest in the transaction. The policy grants standing pre-approval of certain transactions, including (i) certain compensation arrangements of executive officers, (ii) certain
director compensation arrangements, (iii) transactions with another company at which a related partys only relationship is as a non-executive employee, director or beneficial owner of less than 10%
of that companys shares and the aggregate amount involved does not exceed the greater of $200,000 or 2% of the companys total annual revenue, (iv) transactions where a related partys interest arises solely from the ownership
of our common stock and all holders of our common stock received the same benefit on a pro rata basis, and (v) transactions available to all U.S. employees generally.

|Item 14. | Principal Accounting Fees and Services
|-------- | --------------------------------------

For the fiscal years
ended December 31, 2017 and 2016, audit fees paid to KPMG LLP (KPMG) for professional audit services rendered to us were $1.4 million and $2.2 million, respectively. Audit fees include fees for
(a) professional services rendered for the annual audit of the 2017 and 2016 consolidated financial statements, (b) review of the interim consolidated financial statements and (c) services that are typically provided by an independent
registered public accounting firm in connection with statutory and regulatory filings or engagements. No audit related, tax, or other services were rendered to us by KPMG LLP for the fiscal years ended December 31, 2017 and 2016.

Audit Committee Policy on Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm

Our audit committee has
established a policy governing our use of the services of our independent registered public accounting firm. Under this policy, our audit committee is required to pre-approve all audit and non-audit services performed by our independent registered public accounting firm in order to ensure that the provision of such services does not impair the public accountants independence. All fees paid to
KPMG for our fiscal years ended December 31, 2016 and 2017 were pre-approved by our audit committee.
