Epiq Systems Expands E-discovery Market Share With Acquisition

Kansas City, KS (April 4, 2011) — Epiq Systems, Inc. (NASDAQ:EPIQ), a leading global provider of technology solutions for the legal profession, today announced the acquisition of Encore Discovery Solutions for $100 million cash. With this transaction, Epiq further strengthens its worldwide e-discovery franchise providing corporate legal departments and law firms with full-service capabilities to manage electronic information for discovery, investigations, compliance and related legal matters. The transaction has closed and was funded from the company’s credit facility.

Based in Phoenix, Encore Discovery Solutions provides market-proven products and services for electronic evidence processing, document review platforms, and professional services for project management, data collection and forensic consulting.  For 2010, on a pro forma basis, Encore represents an approximate 50% revenue increase to Epiq Systems’ standalone e-discovery segment, which had 2010 operating revenue of approximately $81 million.

In its continuing evaluation of strategic opportunities, Epiq Systems has prioritized the identification of e-discovery candidates with both compatible business strategies and complementary financial profiles. In these respects, Encore represents a natural extension and an attractive market share expansion.

Epiq Systems has a high growth, leading global position in the market for e-discovery technologies and professional services. For 2010, Epiq’s e-discovery business experienced a 92% increase in non-GAAP adjusted EBITDA exclusively through organic growth. Through the Encore acquisition, the company’s e-discovery segment experiences a significant revenue increase and gains immediate access to a high quality customer base having almost no overlap with Epiq’s existing clientele. Encore’s clients will benefit from Epiq Systems’ service capacity, international offices, data centers, and document review services.

While Epiq Systems has developed its e-discovery franchise based on proprietary, internally developed software including its DocuMatrix® review platform and eDataMatrix® evidence processing engine, Encore has approached the market with a selection of licensed third party tools from which clients can choose. Going forward, Epiq Systems will make both solution sets available, thereby offering to customers capabilities of unprecedented breadth and depth. Based on the size, complexity and service level required by each client matter, Epiq will be ideally positioned to present a tailored package of products and services.

Encore’s primary operations and client service facility is located in Phoenix, and they will continue to operate from this office location by blending into Epiq’s total e-discovery service infrastructure.

Tom W. Olofson, chairman and CEO, and Christopher E. Olofson, president and COO of Epiq Systems, stated, “Today’s acquisition further augments and accelerates the opportunity for our highly successful global e-discovery business. Encore has a strong customer base that complements our own, and the company’s Phoenix location is an excellent geographic counterbalance to our own domestic presence in New York. By continuing the availability of both businesses’ products, services and technologies, we offer the industry’s best mixture of resources, experience and subject matter expertise.”

The company expects this to be an accretive transaction and is raising its 2011 non-GAAP EPS objective from a range of $0.85 to $0.90 to a range of $0.89 to $0.94.  The revised objective represents a 20% to 27% increase versus the $0.74 non-GAAP EPS achieved in 2010.  The revised 2011 operating revenue objective is a range of $270 million to $280 million versus $217.6 million achieved in 2010.
