Item 3.01  Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On October 27, 2016, the New York Stock Exchange (“NYSE”) issued a press release announcing that the staff of NYSE Regulation determined to suspend trading immediately and commence proceedings to delist the common stock of Violin Memory, Inc. (“Violin”) (ticker symbol: VMEM) from the NYSE. On October 28, 2016, the NYSE notified Violin in writing of the determination to suspend trading and commence proceedings.

The notification states that NYSE Regulation reached its determination pursuant to Section 802.01B of the NYSE’s Listed Company Manual because Violin is not in compliance with the NYSE’s continued listing standard requiring listed companies to maintain an average global market capitalization over a thirty trading-day period of at least $15,000,000.

The notification further states that Violin has a right to a review of NYSE Regulation’s determination by a Committee of the Board of Directors of the NYSE, and that the NYSE will apply to the Securities and Exchange Commission to delist Violin’s common stock upon completion of all application procedures, including any appeal by Violin of NYSE Regulation’s determination. Violin will consider all of its options, including its option to pursue a review, in responding to the notification.

Violin’s common stock commenced trading on the OTCQX Market on October 28, 2016, and trading will continue under the “VMEM” ticker symbol.
