Exhibit 99.1

Ixia Receives Expected Nasdaq Letter

Intends to Request Hearing before Nasdaq Hearings Panel

CALABASAS, CA — May 6, 2014 – Ixia (Nasdaq: XXIA) announced today that on May 2, 2014 and as expected, the company received a letter from the Listing Qualifications Department of The NASDAQ Stock Market LLC (“Nasdaq”) stating that unless the company requests on or before May 9, 2014 a hearing before a Nasdaq Listing Qualifications Panel (a “Hearings Panel”), the company’s common stock will be delisted due to the company’s non-compliance with Nasdaq Listing Rule 5250(c)(1) (the “Rule”). The Rule requires listed companies to timely file all required periodic financial reports with the Securities and Exchange Commission (the “SEC”). The letter was issued in accordance with standard Nasdaq procedures because of the company’s previously reported delay in filing its Quarterly Report on Form 10-Q for the quarter ended September 30, 2013 (the “Third Quarter Form 10-Q”) and Annual Report on Form 10-K for the fiscal year ended December 31, 2013 (together, the “Reports”).

The company plans to timely request a hearing before a Hearings Panel, and the request will automatically stay the delisting of the company’s common stock on the Nasdaq Global Select Market for a period of 15 days after the deadline for the hearing request (i.e., through May 24, 2014). The company plans in its hearing request to also request that delisting be stayed beyond the 15-day period until such time as the hearing has been held and the Hearings Panel has made its decision. It is within the discretion of the Hearings Panel to grant or deny the company’s request for an extended stay until such time as the Hearings Panel makes its decision regarding the company’s appeal of the delisting determination. If the Hearings Panel grants the company’s request for an extended stay until the issuance of the Hearings Panel’s decision, any potential delisting would be deferred until that time.

At the hearing, the company plans to present an updated plan to regain compliance with the Rule. Following the hearing, the Hearings Panel may in its discretion grant or deny the company an additional extension of time within which to regain compliance with the Rule. Any extension may not, however, extend beyond November 13, 2014 (i.e., the date that is 360 days after the date of the company’s original non-compliance with the Rule).

The company continues to work diligently and to devote substantial resources to complete the Reports and the previously announced restatement of the financial statements contained in its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2013 and June 30, 2013 (together, the “Quarterly Reports”). The company has made substantial progress in these matters and plans to file the Reports and the amendments to its previously filed Quarterly Reports as soon as practicable.
