"The CombiMatrix group's revenues for the second quarter of 2005 were $1,857,000. This represents a gain of 74% over revenues from the first quarter of 2005, and gain of 147% over revenues of the second quarter of 2004. Product and equipment revenues related to CustomArrayTM were $565,000, which represents an increase of 103% relative to such revenues earned in the first quarter of 2005 and over 1200% greater than such revenues for the second quarter of 2004," commented Dr. Amit Kumar, President and CEO of CombiMatrix Corporation. Last quarter we achieved our first one million dollar quarter, and during this quarter we nearly achieved our first two million dollar quarter. The CombiMatrix group continues to execute on its plan as our products become accepted in our industry. In addition to the aforementioned sales growth, we made advances in all facets of our business, and began execution of our diagnostics strategy by establishing CombiMatrix Molecular Diagnostics," concluded Dr. Kumar. ACACIA RESEARCH CORPORATION CONSOLIDATED FINANCIAL RESULTS Consolidated revenues for the second quarter of 2005 were $4,539,000 versus $1,416,000 in the comparable 2004 period. Second quarter 2005 revenues recognized by the CombiMatrix group were $1,857,000, comprised of $1,281,000 in government contract revenues and $576,000 in CustomArrayTM product, equipment and service revenues. Second quarter 2005 revenues recognized by the Acacia Technologies group were $2,682,000, comprised of $832,000 in recurring license fee revenues and $1,850,000 in paid-up license fee revenues. Recurring license fee revenues are recognized from licensees that make recurring quarterly or annual license fee payments under their respective license agreements. Paid-up license fee revenues are recognized from licensees that make paid-up license fee payments for past infringement and future use of our patented technologies, in accordance with their respective license agreements. Certain of our paid-up license agreements provide for potential additional payments to the Acacia Technologies group based on future activities. All of the paid-up license fee revenues recognized in the second quarter of 2005 relate to patents acquired in the January 2005 acquisition of Global Patent Holdings, LLC (the "GPH Acquisition"). Second quarter 2005 license fee revenues included fees from the licensing of our Digital Media Transmission ("DMT(R)") technology, credit card fraud protection technology, multi-dimensional bar code technology, computer simulation technology, high capacity compact disk technology and interactive television technology. 1 The second quarter 2005 consolidated net loss was $5,417,000 versus $4,669,000 in the comparable 2004 period. The second quarter 2005 results include net non-cash charges totaling $1,891,000, comprised primarily of patent amortization charges of $1,610,000 and asset depreciation charges of $266,000. Patent amortization, non-cash stock compensation and asset depreciation charges totaled $865,000 in the comparable 2004 period. The increase in patent amortization charges reflects the amortization of patent related intangibles acquired in connection with the GPH Acquisition. Patent amortization charges will continue to be significant in future periods as the Acacia Technologies group continues to amortize the acquired patent related costs over a weighted average economic useful life of approximately 6 years. The second quarter 2004 results included a non-cash credit of $391,000 related to changes in the fair value of AR-CombiMatrix common stock issuable in connection with certain anti-dilution provisions of the September 2002 settlement agreement with Nanogen, Inc. The anti-dilution provisions expire in September 2005. Second quarter 2005 government contract costs totaled $1,209,000 versus $653,000 in the comparable 2004 period. The change was due to increased costs recognized in connection with the CombiMatrix group's commitments under its biological threat detection cost plus fixed fee contract with the Department of Defense, which was originally awarded in March 2004. As of June 30, 2005, the biological threat detection contract is approximately 68% complete. Second quarter 2005 internal research and development expenses were $1,415,000 versus $1,409,000 in the comparable 2004 period. During the second quarter of 2005 and 2004, the CombiMatrix group continued internal research and development efforts to improve and expand the CombiMatrix group's technology and product offerings. Government contract costs and research and development expense were incurred solely by the CombiMatrix group. Marketing, general and administrative expenses for the second quarter of 2005 increased to $4,261,000 from $3,388,000 in the comparable 2004 period, due primarily to the addition of licensing and business development personnel for the Acacia Technologies group, an increase in the Acacia Technologies group's consulting expenses related to a consulting agreement executed with the former CEO of Global Patent Holdings, LLC and an increase in marketing and sales expenses related to commercial sales of the CombiMatrix group's CustomArray(TM) products and services. Second quarter 2005 patent related legal expenses, comprised solely of costs incurred by the Acacia Technologies group, were $536,000 versus $576,000 in the comparable 2004 period. Second quarter 2005 patent related legal expenses included $278,000 in patent related prosecution and enforcement costs incurred by certain of the companies acquired in the GPH Acquisition transaction. Excluding the impact of the GPH Acquisition, patent related legal expenses decreased to $258,000 in the second quarter of 2005 due to a decrease in costs incurred in connection with the Acacia Technologies group's ongoing DMT patent commercialization and enforcement programs, including decreased legal costs related to new patent claims and a decrease in patent enforcement costs related to ongoing DMT patent related litigation. DMT related legal fees paid to outside attorneys are incurred based on actual time and out-of-pocket expenses incurred by external counsel and fluctuate from period to period based on patent enforcement and prosecution activity in each period. DMT related legal expenses will fluctuate in future periods based on actual outside patent counsel fees incurred in connection with the Acacia Technologies group's ongoing DMT patent commercialization and enforcement programs. In the second quarter of 2005, the Acacia Technologies group recognized contingent legal fee expenses totaling $592,000 and inventor royalty expenses totaling $528,000, in connection with the recognition of related paid-up license fee revenues. FINANCIAL CONDITION Total consolidated assets were $116,757,000 as of June 30, 2005 compared to $88,327,000 as of December 31, 2004. Cash and cash equivalents and short-term investments on a consolidated basis totaled $55,331,000 as of June 30, 2005 compared to $52,358,000 as of December 31, 2004. In June 2005, Acacia Research Corporation obtained commitments to purchase approximately $3.2 million of its Acacia Research-CombiMatrix common stock in a registered direct offering, which closed on July 5, 2005. Under the terms of the transaction, 1,400,444 shares of Acacia Research-CombiMatrix common stock were sold at $2.25 per share to a select group of institutional investors. The net proceeds, totaling approximately $3.1 million, which are net of offering costs, were allocated to the CombiMatrix group. All of the shares of Acacia Research-CombiMatrix common stock were offered by Acacia Research Corporation pursuant to an effective registration statement previously filed with the Securities and Exchange Commission. 2 ACACIA TECHNOLOGIES GROUP (A DIVISION OF ACACIA RESEARCH CORPORATION) FINANCIAL RESULTS License fee revenues for the second quarter of 2005 were $2,682,000 versus $666,000 in the comparable 2004 period. Second quarter 2005 revenues recognized by the Acacia Technologies group included $832,000 in recurring license fee revenues and $1,850,000 in paid-up license fee revenues. Recurring license fee revenues are recognized from licensees that make recurring quarterly or annual license fee payments under their respective license agreements. Paid-up license fee revenues are recognized from licensees that make paid-up license fee payments for past infringement and future use of our patented technologies, in accordance with their respective license agreements. Certain of our paid-up license agreements provide for potential additional payments based on future activities. All of the paid-up license fee revenues recognized in the second quarter of 2005 relate to patents acquired in the January 2005 GPH Acquisition. Second quarter license fee revenues included fees from the licensing of our Digital Media Transmission ("DMT(R)") technology, credit card fraud protection technology, multi-dimensional bar code technology, computer simulation technology, high capacity compact disk technology and interactive television technology. The second quarter 2005 division net loss was $1,760,000 versus $1,153,000 in the comparable 2004 period. Included in the second quarter 2005 divisional results are non-cash patent amortization charges totaling $1,336,000 versus $125,000 in the comparable 2004 period. Patent amortization charges increased in the second quarter of 2005 due to the amortization of patent related intangibles acquired in connection with the GPH Acquisition. Patent amortization charges will continue to be significant in future periods as we continue to amortize the acquired patent related costs over a weighted average economic useful life of approximately 6 years. Second quarter 2005 marketing, general and administrative expenses increased to $1,759,000 from $1,160,000 in the comparable 2004 period, due primarily to the addition of licensing and business development personnel for the Acacia Technologies group and an increase in consulting expenses related to a consulting agreement executed with the former CEO of Global Patent Holdings. Second quarter 2005 patent related legal expenses were $536,000 versus $576,000 in the comparable 2004 period. Second quarter 2005 patent related legal expenses included $278,000 in patent related prosecution and enforcement costs incurred by certain of the companies acquired in the GPH Acquisition transaction. Excluding the impact of the GPH Acquisition, patent related legal expenses decreased to $258,000 in the second quarter of 2005 due to a decrease in costs incurred in connection with the Acacia Technologies group's ongoing DMT patent commercialization and enforcement programs, including decreased legal costs related to new patent claims and a decrease in patent enforcement costs related to ongoing DMT patent related litigation. DMT related legal fees paid to outside attorneys are incurred based on actual time and out-of-pocket expenses incurred by external counsel and fluctuate from period to period based on patent enforcement and prosecution activity in each period. DMT related legal expenses will fluctuate in future periods based on actual outside patent counsel fees incurred in connection with the Acacia Technologies group's ongoing DMT patent commercialization and enforcement programs. In the second quarter of 2005, the Acacia Technologies group recognized contingent legal fee expenses totaling $592,000 and inventor royalty expenses totaling $528,000, in connection with the recognition of related paid-up license fee revenues. It is anticipated that the majority of litigation expenses associated with the recently acquired patent portfolios will be incurred on a contingency basis where patent attorney fees are paid out of license fee revenues collected based on a contractual percentage. In connection with the GPH Acquisition, we expect that other legal expenses associated with the maintenance, licensing and enforcement of our patented technologies, will increase in future periods as we continue to roll out our licensing programs for our recently acquired patented technologies. 3 FINANCIAL CONDITION Total assets for the Acacia Technologies group were $67,658,000 as of June 30, 2005 compared to $33,058,000 as of December 31, 2004.
