c/o Splunk Inc.

270 Brannan Street

San Francisco, CA

Dear Teresa:

I am thrilled and delighted to offer you the position of President, Go To Market of Splunk Inc. (the “Company”), reporting to me. Your primary work location will be your home office in Sarasota, Florida. We are very excited to have you join the team. In your role, you will have the opportunity to make a meaningful impact on our future success. Understandably, this offer is contingent upon you fully cooperating with, and satisfactorily completing, and clearing background, reference and conflicts checks. Here are the terms of our proposed offer (the “Offer”):

1.Annual Salary; Executive Bonus. Your gross base salary will be $600,000 per year, less applicable deductions and withholdings, and paid in accordance with the Company’s standard payroll practices. In addition, you will be eligible to participate in Splunk's Executive Bonus Plan beginning with the Executive Bonus Plan in effect for the Company’s 2022 fiscal year. Your initial annualized target bonus will be 100% of your annual base salary. Your actual bonus amount will be based on actual achievement of Company financial goal(s), as determined by the Compensation Committee of our Board of Directors (“Compensation Committee”) and prorated as of the Effective Date (defined below). Under current practices (which may change in the future), you will be paid a mid-fiscal-year bonus of up to 50% of your annualized target bonus, pro-rated for the time you have worked during the fiscal year. Any mid-fiscal-year bonus will be based on the Company's forecasted annual achievement of the bonus plan’s performance metrics as of the end of the fiscal second quarter. Your actual mid-fiscal-year bonus amount will be included in the calculation of your annual bonus, meaning that your year-end bonus payment will be equal to your calculated annual bonus amount, less any mid-fiscal-year bonus amount already paid for that fiscal year. The year-end bonus payment will be made in the nearest pay period following the final approval date after the completion of the fiscal year and after the Compensation Committee's review and approval of executive bonuses, but in no event later than two and a half months following the end of the Company’s fiscal year. Note that all payments to you will be made after applicable withholdings.

2.Start Date. Your start date will be April 19, 2021 (the “Effective Date”).

3.Signing Bonus. We are pleased to offer you a cash signing bonus in the amount of $3,250,000, less all applicable deductions and withholdings.  This bonus will be payable approximately 30 days after your start date.  If you voluntarily resign from the Company for any reason within 12 months following your start date, you agree to reimburse the Company for 100% of the cash signing bonus. If you voluntarily resign after the 12 month anniversary of your start date, you agree to reimburse the Company for up to 50% of the of the cash signing bonus on a prorated basis with the amount to be reimbursed determined by subtracting the number of months completed after the 12 month anniversary of your start date from 12 and divided by 12.  By your signature on this offer letter, if you voluntarily resign before the date that is 24 months from your start date, you authorize the Company to withhold the entire cash signing bonus amount that is repayable to the Company under this paragraph from all amounts otherwise due and payable to you on termination of employment if, and as permitted by applicable law.  If any amount remains unpaid, you agree to promptly repay the Company the remaining unpaid amount, in full.

4.Benefits. You will be eligible to participate in the healthcare, 401(k), employee stock purchase and other employee benefit plans established for our employees and executives, subject to the eligibility criteria and other terms and conditions for such plans. You will be eligible to receive healthcare benefits on your first day of active, full-time employment. You will be entitled to 15 days of Personal Time-Off (PTO) annually, accrued on a semi-monthly basis in accordance with Company policy.

5.Equity. We will recommend to the Compensation Committee that you be granted a total new hire equity grant with a value of $16,000,000 under the Company’s 2012 Equity Incentive Plan or its successor (the “EIP”) and the applicable award agreement approved for grants thereunder. $10,900,000 of the new hire grant will be granted in Restricted Stock Units (“RSUs”), of which approximately $7,500,000 will vest over approximately 4 years (the “4-Year RSUs”), with 25% of the 4-Year RSUs vesting on or about March 10, 2022 and 1/16th of the 4-Year RSUs vesting quarterly thereafter as specified in your 4-Year RSU agreement, so long as you remain employed by the Company. Approximately $3,400,000 will vest over approximately 3 years (the “3-Year RSUs”), with 33.33% of the 3-Year RSUs vesting on or about March 10, 2022 and 1/12th of the 3-Year RSUs vesting quarterly thereafter as specified in your 3-Year RSU agreement, so long as you remain employed by the Company. The remaining portion of the equity grant will be in the form of Performance Stock Units (“PSUs”) with a target value of approximately $5,100,000, which PSUs will vest pursuant to the terms established by the Compensation Committee, including without limitation the relevant performance metrics and measurement period, as well as vesting terms set forth in your PSU agreement. The PSUs, if earned, will vest over approximately 3 years with 33.33% of the PSUs vesting on or about March 10, 2022 and 1/12th of the PSUs vesting quarterly thereafter as specified in your PSU agreement, so long as you remain employed by the Company. Each dollar amount discussed in this section will be converted into a number of shares by dividing the dollar amount by the average closing

stock price for the 60 trading days ending the day before the grant date, rounded down to the nearest whole unit.

6.Confidentiality. You agree not to disclose the existence of this Offer, its proposed terms or your joining the Company to any third party prior to the public announcement of such by the Company, with the exception of disclosure to your legal and financial advisors and current manager or employer, provided that each has agreed to maintain confidentiality.

In addition, you must not violate any other obligation you may have to any former employer or other third party. During the period that you render services to the Company, you agree that you will not engage in any employment, business or activity that is in any way competitive with the business or proposed business of the Company. You will disclose to the Company, in writing, any other employment, business or activity that you are currently associated with or participate in that competes with the Company and that you become associated with during the period that you render services to the Company. You will not assist any other person or organization in competing with the Company or in preparing to engage in competition with the business or proposed business of the Company. By signing this Offer, you certify that your employment with the Company will not violate any contractual or other legal obligation that would prohibit or limit you from performing your duties to the Company.

7.At-Will Employment. During your entire employment you will be an at-will employee of the Company, which means the employment relationship can be terminated by either of us for any lawful reason or no reason, at any time, with or without prior notice and with or without Cause. Your participation in any equity or benefit program does not assure you of continuing employment for any particular period of time. Any modification or change in your at-will employment status may only occur by way of a written agreement signed by you and the Chief Executive Officer of the Company.

8.Severance. We will recommend to the Compensation Committee that you receive the following severance benefits.

(a)Separation in Event of Termination Within the 3-Month Period Before or 18-Month Period Following a Change in Control. In the event of your involuntary separation from employment with the Company without Cause or for Good Reason, in each case within the period that begins after the signing of a definitive agreement that ultimately results in a Change in Control (defined below) within three

(3) months of its signing or within eighteen (18) months following a Change in Control (“Change in Control Period”), then, in addition to any accrued compensation, and provided that you deliver to the Company a signed release of claims in favor of the Company (“Release”), and satisfy all conditions to make the Release effective within sixty (60) days following your separation from service, you shall be entitled to the benefits as set forth below:

(i)Lump sum payment equal to twelve (12) months of your then-current base salary, plus 100% of your annual target bonus as in effect in the fiscal year of termination;

(ii)Provided you timely elect to continue health coverage under COBRA, payment or reimbursement, as applicable, for any monthly COBRA premium payments made by you in the twelve (12) months following your separation from service. If at the time you separate from service, it would result in a Company excise tax to reimburse you for COBRA premiums, then no such premiums will be reimbursed and if doing so would not cause imposition of an excise tax, you will be paid a single lump sum of $24,000; and

(iii)Acceleration of vesting as to all then-unvested shares or rights subject to all equity awards which have been granted to you. You shall have six (6) months following your separation from service from the Company in which to exercise any stock options that have been granted to you.

(b)Severance in Event of Termination Without Cause Outside the Change in Control Period. In the event of your involuntary separation from employment with the Company without Cause not during the Change in Control Period, then, in addition to any accrued compensation, and provided that you deliver to the Company a signed Release and satisfy all conditions to make the Release effective within sixty (60) days following your separation from service, you shall be entitled to benefits as set forth below:

(i)Lump sum payment equal to six (6) months of your then-current base salary, plus a pro-rated portion of your annual target bonus for the time you are actively employed in the fiscal year of termination;

(ii)Provided you timely elect to continue health coverage under COBRA, payment or reimbursement, as applicable, for any monthly COBRA premium payments made by you in the six (6) months following your separation from service. If at the time you separate from service, it would result in a Company excise tax to reimburse you for COBRA premiums then no such premiums will be reimbursed and if doing so would not cause imposition of an excise tax, you will be paid a single lump sum of $12,000; and

(iii)Acceleration of vesting as to the number of shares or rights subject to all equity awards which have been granted to you as would have vested in the six (6) months following your separation from service. You shall have six (6) months following your separation from service from the Company in which to exercise any vested options that have been granted to you.

9.Section 409A Matters.

(a)For purposes of this Offer, no payment will be made to you upon termination of your employment unless such termination constitutes a “separation from service” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and Section 1.409A-l(h) of the regulations promulgated thereunder.

(b)To the extent any payments to which you become entitled under this Offer, or any agreement or plan referenced herein, in connection with your separation from service from the Company constitute deferred compensation subject to Section 409A of the Code (the “Deferred Payments”), such payments will be paid on, or in the case of installments, will not commence, until the sixtieth (60th) day following your separation from service, or if later, such time as required by Section 9(c). Except as required by Section 9(c), any installment payments that would have been made to you during the sixty (60) day period immediately following your separation from service but for the preceding sentence will be paid to you on or around the sixtieth (60th) day following your separation from service and the remaining payments will be made as provided herein.

(c)If you are deemed at the time of such separation from service to be a “specified employee” under Section 409A of the Code, then any Deferred Payment(s) shall not be made or commence until the earliest of (i) the expiration of the six (6)-month period measured from the date of your “separation from service” (as such term is at the time defined in Treasury Regulations under Section 409A of the Code) with the Company or (ii) the date of your death following such separation from service; provided, however, that such deferral shall only be effected to the extent required to avoid adverse tax treatment to you, including (without limitation) the additional twenty percent (20%) tax for which you would otherwise be liable under Section 409A(a)(l)(B) of the Code in the absence of such deferral. Upon the expiration of the applicable deferral period, any payments which would have otherwise been made during that period (whether in a single sum or in installments) in the absence of this paragraph shall be paid to you or your beneficiary in one lump sum.

(d)To the extent any payments to which you become entitled under this Offer, or any agreement or plan referenced herein, in connection with your separation from service from the Company constitute deferred compensation subject to Section 409A of the Code, you and the Company may make changes to this Offer to avoid adverse tax consequences under Section 409A. Each payment and benefit payable hereunder is intended to constitute a separate payment for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations.

10.Parachute Payments.

(a)Reduction of Severance Benefits. Notwithstanding anything set forth herein to the contrary, if any payment or benefit that you would receive from the Company or any other party whether in connection with the provisions herein or otherwise (the “Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the

excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment will be equal to the Best Results Amount. The “Best Results Amount” will be either (x) the full amount of such Payment or (y) such lesser amount as would result in no portion of the Payment being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local employment taxes, income taxes and the Excise Tax, results in your receipt, on an after-tax basis, of the greater amount notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting parachute payments is necessary so that the Payment equals the Best Results Amount, reduction will occur in the following order: reduction of cash payments; cancellation of accelerated vesting of stock awards; and reduction of employee benefits. In the event that acceleration of vesting of stock award compensation is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant of your equity awards.

(b)Determination of Excise Tax Liability. The Company will select a professional services firm to make all of the determinations required to be made under these paragraphs relating to parachute payments. The Company will request that firm provide detailed supporting calculations both to the Company and you prior to the date on which the event that triggers the Payment occurs if administratively feasible, or subsequent to such date if events occur that result in parachute payments to you at that time. For purposes of making the calculations required under these paragraphs relating to parachute payments, the firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith determinations concerning the application of the Code. The Company and you will furnish to the firm such information and documents as the firm may reasonably request in order to make a determination under these paragraphs relating to parachute payments. The Company will bear all costs the firm may reasonably incur in connection with any calculations contemplated by these paragraphs relating to parachute payments. Any such determination by the firm will be binding upon the Company and you, and the Company will have no liability to you for the determinations of the firm.

11.Definitions.

You further understand that this agreement to arbitrate also applies to any disputes that the Company may have with you. You and the Company each retain their right to and shall not be prohibited or limited from seeking or obtaining equitable relief from a court having jurisdiction over the parties.

arbitration. All such claims will be decided on an individual basis in arbitration pursuant to the parties’ agreement to arbitrate. The parties expressly waive any right with respect to any covered claims to submit, initiate, or participate as a plaintiff, claimant or member in a class or collective action, regardless of whether the action is filed in arbitration or in court. Claims may not be joined or consolidated in arbitration with disputes brought by other individuals, unless agreed to in writing by all parties.

Any issue concerning the validity of this class action or collective action waiver must be decided by a Court and an arbitrator shall not have authority to consider the issue of the validity of this waiver. If for any reason this class or collective action waiver is found to be unenforceable, the class action or collective action claim may only be heard in court and may not be arbitrated. The arbitrator shall not have authority to hear or decide class or collective actions. The arbitrator’s authority to resolve disputes and make awards under this Offer is limited to disputes between: (i) you and the Company; and (ii) you and any current or former officers directors, employees or agents of the Company, if such individual is sued for conduct arising out of his or her employment. No arbitration award or decision will have any preclusive effect as to issues or claims in any dispute with anyone who is not a named party to the arbitration. This agreement to arbitrate supersedes all arbitration agreements that previously existed between the employee and the Company.

(c)Procedure. You agree that any arbitration will be administered by Judicial Arbitration & Mediation Services, Inc. (“JAMS”), pursuant to its employment arbitration rules & procedures (the “JAMS rules”), which are available at http://www.jamsadr.com/rules-employment-arbitration/ and from Human Resources. You agree that the arbitrator shall issue a written decision on the merits. You also agree that the arbitrator shall have the power to award any remedies available under applicable law. You agree that the decree or award rendered by the arbitrator may be entered as a final and binding judgment in any court having jurisdiction thereof. You understand that the Company will pay for any administrative or hearing fees charged by the arbitrator or JAMS except that you shall pay any filing fees associated with any arbitration that you initiate, but only so much of the filing fees as you would have instead paid had you filed a complaint in a court of law. You agree that the arbitrator shall administer and conduct any arbitration in accordance with California law, including the California Code of Civil Procedure and the California Evidence Code, and that the arbitrator shall apply substantive and procedural California law to any dispute or claim, without reference to rules of conflict of law. To the extent that the JAMS rules conflict with California law, California law shall take precedence. You agree that any arbitration hearing under this Offer shall be conducted in San Francisco County, California.

(d)Remedy. Except as provided by the Act and this Offer, arbitration shall be the sole, exclusive, and final remedy for any dispute between you and the Company. Accordingly, except as provided for by the Act and this Offer, neither you nor the Company will be permitted to pursue court action regarding claims that are subject to arbitration.

(e)Administrative relief. This Offer does not prohibit you from pursuing an administrative claim with a local, state, or federal administrative body or government agency that is authorized to enforce or administer laws related to employment, including, but not limited to, the Department of Fair Employment and Housing, the Equal Employment Opportunity Commission and the National Labor Relations Board. This also includes claims for workers’ compensation benefits, unemployment insurance, or state or federal disability insurance. Moreover, this Offer does not apply to any other dispute or claim that has been expressly excluded from arbitration by statute. Nothing in this Offer prohibits or restricts you from initiating communications directly with, responding to any inquiry from, or providing information or testimony to or before, the Securities and Exchange Commission (“SEC”), Department of Justice (“DOJ”), or any other governmental agency or department or self-regulatory organization, about actual or potential violations of laws or regulations (including lawfully reporting fraud, waste or abuse). You are not required to obtain Splunk’s prior authorization before engaging in such communications, nor are you required to inform Splunk about such communications. This Offer does, however, preclude you from pursuing court action regarding any such claim, except as permitted by law.

(f)Voluntary nature of agreement. You acknowledge and agree that you are executing this Offer voluntarily and without any duress or undue influence by the Company or anyone else. You further acknowledge and agree that you have carefully read this Offer and that you have asked any questions needed for you to understand the terms, consequences, and binding effect of this Offer and fully understand it, including that you are waiving your right to a jury trial. You agree that you have been provided an opportunity to seek the advice of an attorney of your choice before signing this Offer.
