On January 8, 2019, Apptio, Inc. (“Apptio”) held a special meeting of stockholders (the “Special Meeting”) at Apptio’s principal executive offices in Bellevue, Washington.

As of December 6, 2018, the record date for the Special Meeting, there were 45,566,879 shares of Apptio Class A common stock outstanding and entitled to vote. At the Special Meeting, 32,219,140 shares, or approximately 70.71% of all outstanding shares of Class A common stock, were present either in person or by proxy.

At the Special Meeting, two proposals were considered:

(1) The proposal to adopt the Agreement and Plan of Merger, dated as of November 9, 2018 (the “Merger Agreement”), by and among Apptio, Bellevue Parent, LLC (“Parent”), and Bellevue Merger Sub, Inc. (“Merger Sub”). Parent and Merger Sub are entities that are affiliated with Vista Equity Partners Fund VI, L.P., a Cayman Islands exempted limited partnership (“Vista Fund VI”). Pursuant to the terms of the Merger Agreement, Merger Sub will merge with and into Apptio, with Apptio continuing as the surviving corporation and a wholly owned direct subsidiary of Parent (the “Merger Proposal”).

(2) The proposal to adjourn the Special Meeting to a later date or dates if necessary or appropriate to solicit additional proxies if there were insufficient votes to adopt the Merger Agreement at the time of the Special Meeting (the “Adjournment Proposal”).

At the Special Meeting, the Merger Proposal was approved by stockholders. Sufficient votes were also received to approve the Adjournment Proposal, but such an adjournment was not necessary in light of the approval of the Merger Proposal. The table below shows the final voting results from the Special Meeting.
