MRV Announces Second Quarter 2012 Financial Results

CHATSWORTH, Calif., August 9, 2012 — MRV Communications, Inc. (OTCQB: MRVC) (“MRV” or the “Company”), a leading provider of optical communications network infrastructure equipment and integration and managed services, today announced financial results for the second quarter ended June 30, 2012.

MRV reported second quarter 2012 revenue of $55.0 million, compared with revenue of $48.4 million in the first quarter of 2012 and $59.2 million in the second quarter of 2011. The sequential revenue increase of 14% was driven by higher Network Equipment revenue, primarily at OCS, attributable to growth in service revenue and out-of-band networking product and higher Network Integration revenue due to the recognition of previously deferred revenue. The year-over-year decline of 7% was due to a 13% decline in the Network Equipment group attributable to lower service and product revenues across all regions in OCS and a 4% decline in the Network Integration group attributable to a continued weak European telecom marketplace.

Gross margin for the second quarter of 2012 was 34.4%, compared with 35.5% in the first quarter of 2012 and 40.0% in the second quarter of 2011. The year over year decline in gross profit was impacted by the decline in revenue at the Company’s Network Integration and Network Equipment groups. In the Network Equipment group, gross margins were negatively impacted by a more competitive operating environment, which increased pricing pressure, and a write down of inventory held for sale and service support. In the Network Integration group, margins were down due to highly competitive European markets that are driving increasing pricing pressure, and a change in product and service revenue mix.

Operating expenses in the second quarter of 2012 were $22.3 million, or 40% of revenue, and included a $3.7 million goodwill impairment charge related to the Company’s subsidiary in Scandinavia. Excluding this charge, operating expenses in the second quarter were $18.6 million, or 34% of revenue, compared with $20.8 million, or 43% in the first quarter of 2012 and $21.9 million, or 37% of revenue in the second quarter of 2011. The year-over-year consolidated decrease in operating expenses reflects cost cutting initiatives including $1.9 million in lower labor cost at the operating units during the second quarter of 2012, $0.9 million in lower consulting fees, and lower organizational support cost, which were partially offset by an increase of $0.5 million in severance expense for an officer at our subsidiary in France. The year over year decrease also included several charges in the second quarter of 2011 that did not recur in 2012, including $0.7 million of legal costs related to Board activities and $0.6 million in share-based compensation paid to our former CEO.

Operating loss for the second quarter of 2012 was $3.4 million, and included a $3.7 million goodwill impairment charge related to the Company’s subsidiary in Scandinavia. Excluding this charge, the operating profit in the second quarter was $0.3 million, compared with a loss of $3.6 million in the first quarter of 2012 and an operating profit of $1.8 million in the second quarter of 2011. Operating losses included share-based compensation expense of $0.2 million and $0.8 million in the second quarter of 2012 and 2011, respectively.

As publicly announced on May 2, 2012, MRV’s Board of Directors declared a special dividend of $0.30 per share payable on May 25, 2012 to stockholders of record as of May 16, 2012 and therefore MRV disbursed $47.3 million to investors in the second quarter of 2012.

A more detailed discussion of MRV’s 2012 second quarter financial results, including an analysis by business segment, is included in the Management’s Discussion and Analysis section of the Company’s quarterly report filed with the Securities and Exchange Commission (“SEC”) on Form 10-Q today.

Commenting on the Company’s financial results, Barry Gorsun, MRV’s chief executive officer, stated “While the markets we sell into have been experiencing near term weakness, we had several key successes in the quarter and we continue to expand our customer footprint among existing customers as well as added 41 new customers. A top tier service provider recently selected MRV’s OptiSwitch® and ProVision® solutions for an international metro-Ethernet deployment. Additionally, we continue to gain new data center and content delivery customers and increase sales for our 4G backhaul solutions.”

“During the quarter our OCS division expanded its award winning Pro-Vision product family to support the recently defined Metro Ethernet Forum specifications for Carrier Ethernet 2.0 to enable differentiated services over managed and interconnected global Ethernet networks. We will continue to leverage our technology and resources to deliver innovative products to key segments of our markets.”

Mr. Gorsun continued, “As we separately announced today, we have concluded our review of strategic alternatives and have decided to pursue divestitures of our Network Integration businesses and will be retaining, investing and building our core Optical Communications Systems business. OCS’s markets are poised for significant long term growth due to rising demand for bandwidth intensive applications, mobility and cloud computing that are leading carriers to upgrade their infrastructure and networks.  With our renewed focus on supporting the next generation products in our pipeline, we believe that we will be well-positioned to support our customers’ expanding needs and capitalize on the growth of this market.”

Proposed Transactions

As set forth in MRV’s preliminary proxy statement filed on Schedule 14A with the SEC on August 9, 2012, the Company is seeking stockholder approval for two transactions in the Company’s Network Integration business. The Company has entered into a sale purchase agreement for the sale of its French subsidiary, Interdata, and it has entered into a letter of intent which anticipates a potential sale of its Swedish subsidiary, Alcadon-MRV AB. MRV has also retained investment bank Headwaters BD, LLC,  to evaluate and explore strategic alternatives for its Italian subsidiary, Tecnonet S.p.A. A detailed discussion of MRV’s proposed sale of Interdata and Alcadon can be found in its preliminary proxy statement on file with the SEC.
