NEWS RELEASE

For Immediate Release

Xyratex Ltd Announces Results for the Third Quarter Fiscal Year 2013

Havant, UK — October 3, 2013 — Xyratex Ltd (Nasdaq: XRTX), a leading provider of data storage technology, today announced results for the third fiscal quarter ended August 31, 2013. Revenues for the third quarter were $217.3 million, a decrease of 21% compared to revenues of $275.7 million for the same period in the prior year. The decline year over year was principally related to the continued reduction in revenue from NetApp with the current program coming to an end in our current quarter as previously announced.

For the third quarter, GAAP net income was $2.4 million, or $0.08 per diluted share, compared to GAAP net income of $7.7 million, or $0.28 per diluted share, in the same period last year. Non-GAAP net income was $5.9 million, or $0.21 per diluted share, compared to non-GAAP net income of $10.3 million, or $0.37 per diluted share, in the same quarter a year ago(1).

Gross profit margin in the third quarter was 20.9%, compared to 18.5% in the same period last year and 22.0% in the prior quarter. The increase from last year primarily reflected a favorable variation in customer and product mix in our Enterprise Data Storage Solutions product segment. The decrease from the prior quarter primarily reflected a variation in product mix in our Hard Disk Drive (HDD) Capital Equipment segment.

Today, the Company also announced that its Board of Directors has approved a quarterly cash dividend of $0.075 per share, unchanged from the prior quarter. The dividend will be payable on November 1, 2013 to shareholders of record as of the close of business on October 17, 2013. This dividend represents a quarterly payout of approximately $2.1 million in aggregate, or $8.4 million on an annualized basis.

“Our third quarter results were at the higher end of our expectations, reflecting lower overall expenses and approximately $5 million of revenue from the HDD Capital Equipment business which had previously been planned for the fourth quarter. I am encouraged by the improvements in our customer relationships and our investments in technology, specifically around cloud and flash, and the opportunities that I believe will be created as a result. In our Enterprise Data Storage Solutions business, we recently introduced our 12Gb/s SAS technology into our Onestor line of enterprise class modular storage enclosure. This first-to-market technology has recently been accepted as the next generation technology by one of our significant Tier 1 customers, which is a significant opportunity for Xyratex,” said Ernie Sampias, CEO, “Within our Clusterstor product line, we achieved a number of design wins during the third quarter in vertical markets including academia, oil and gas and the financial sector. Our HDD Capital Equipment business continues to work very closely with our HDD partners. I am encouraged with the opportunities that are being created as a result of these partnerships such as technologies that support higher capacity HDDs.”

Business Outlook

The following statements are based on current expectations. These statements are forward-looking, and actual results may differ materially.

·                  Revenue in the fourth fiscal quarter of 2013 is projected to be in the range of $190 million to $220 million.

·                  Fully diluted earnings (loss) per share is anticipated to be between a loss of $0.09 and earnings of $0.15 on a GAAP basis in the fourth quarter.

Conference Call Information

The company will host a conference call to discuss its results at 1:30 p.m. PT/4:30 p.m. ET on Thursday October 3, 2013.

The conference call can be accessed online via the company’s website www.xyratex.com/investors, or by telephone as follows:

A replay will be available via the company’s website www.xyratex.com/investors, or can be accessed by telephone through October 10, 2013 as follows:

(1) Non-GAAP net income and diluted earnings per share exclude (a) amortization of intangible assets, (b) equity compensation expense, (c) the tax effects related to (a) and (b), (d) the recognition of a Malaysia deferred tax asset in the first quarter of fiscal 2012 and (e) the tax expense resulting from a reduction in the deferred tax asset caused by a fall in U.K. tax rates. Reconciliation of non-GAAP net income and diluted earnings per share to GAAP net income and GAAP diluted earnings per share is included in a table immediately following the condensed consolidated statements of cash flow.

The intention in providing these non-GAAP measures is to provide supplemental information regarding the company’s operational performance while recognizing that they have material limitations and that they should only be referred to with reference to, and not considered to be a substitute for, or superior to, the corresponding GAAP measure. The financial results calculated in accordance with GAAP and reconciliations of these non-GAAP measures to the comparable

3

GAAP measures should be carefully evaluated. The non-GAAP financial measures used by us may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.

The company believes that the provision of these non-GAAP financial measures is useful to investors and investment analysts because it enables comparison to the company’s historical operating results, those of competitors and other industry participants and also provides transparency to the measures used by management in operational and financial decision making. In relation to the specific items excluded: (a) intangible assets represent costs incurred by the acquired business prior to acquisition, are not cash costs and will not be replaced when the assets are fully amortized and therefore the exclusion of these costs provides management and investors with better visibility of the costs required to generate revenue over time; (b) equity compensation expense is non-cash in nature and is outside the control of management during the period in which the expense is incurred; (c) the exclusion of the related tax effects of excluding items (a) and (b) is necessary to show the effect on net income of the change in tax expense that would have been recorded if these items had not been incurred; (d) the recognition of the Malaysia deferred tax asset relates to the non-renewal of certain tax incentive arrangements in 2012, is non-recurring and will reverse if the incentive arrangements are renewed and (e) the impact of the reduction in U.K. tax rates is non-cash and not comparable across periods or with other companies due to the existence of a significant U.K. related deferred tax asset which is expected to reduce over time.
