Item 5.03  Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On March 10, 2016, the board of directors (the “Board”) of Splunk Inc. (“Splunk”) approved amendments to the Amended and Restated Bylaws (the “Bylaws”) of Splunk to implement proxy access.

Section 2.15 has been added to the Bylaws to allow a stockholder or a group of no more than 20 stockholders (or 25 stockholders, if Splunk’s annual revenues are greater than $4 billion for the most recently completed fiscal year) that has maintained continuous ownership of 3% or more of Splunk’s common stock for at least three years to include in Splunk’s proxy materials for an annual meeting of stockholders a number of director nominees not to exceed 20% (if there are 10 or more directors in office) or 25% (if there are nine or fewer directors in office) of the directors then in office, but in no case less than one nominee. Proxy access will first be available in connection with Splunk’s 2017 annual meeting of stockholders.

Splunk engaged in discussions with a number of its stockholders to assess their views on appropriate proxy access terms, allowing the Board to implement terms that it believes will provide meaningful proxy access rights for stockholders while furthering the long-term interests of Splunk and its stockholders.

The foregoing summary is qualified in its entirety by reference to the full text of the Bylaws, a copy of which is included as Exhibit 3.1 to this report and incorporated by reference.
