XOMA Reports Third Quarter 2007 Financial Results

BERKELEY, Calif., Nov. 8, 2007 (PRIME NEWSWIRE) -- XOMA Ltd. (Nasdaq:XOMA), a leader in the discovery and development of therapeutic antibodies, today announced its results for the quarter ended September 30, 2007.

"XOMA's successful third quarter highlights the value of our antibody discovery and development technologies and the overall strength of our antibody business," Steven Engle, Chairman and Chief Executive Officer of XOMA, commented. "Our financial results for the period were excellent, supported by the continued growth of our royalty revenues and license fees. Pfizer, the world's largest pharmaceutical company, in advance of their planned expansion in biotherapeutics, entered a major license agreement for access to our bacterial cell expression technology. Terms of the agreement include $30 million in cash, which was recognized in full during this quarter, and potential milestones and royalties on BCE-derived products. Adding to these achievements, we advanced the Phase 1 development of XOMA 052, a potent monoclonal antibody that targets IL-1 beta. We are excited about the multi-indication potential of XOMA 052 and are actively evaluating clinical plans for its expanded development in 2008."

Third Quarter 2007 Financial Results

XOMA's total revenues were $43.1 million in the third quarter of 2007, an increase of $35.7 million over the third quarter of 2006. Growth in revenues primarily reflects the license fee of $30.0 million received from Pfizer, increases in royalty revenues from Genentech's LUCENTIS(r) and RAPTIVA(r) products, and increased activities in our contracts with companies including Schering-Plough Research Institute and Takeda Pharmaceutical Company Limited, and with the National Institute of Allergy and Infectious Diseases.

The operating income for the third quarter was $22.7 million in 2007 compared to an operating loss of $9.5 million in 2006, reflecting higher revenue in 2007 partially offset by an increase in operating costs primarily related to personnel-related costs and certain other expenses. Net income for the third quarter of 2007 was $21.8 million or $0.16 per diluted share or $0.17 per basic share, compared with a net loss of $10.8 million or $0.11 per share for the quarter ended September 30, 2006. A more detailed discussion of XOMA's third quarter 2007 financial results is provided below and in the Company's Form 10-Q filing.

Third Quarter 2007 Highlights


 * Steven Engle, Chief Executive Officer and President of XOMA, was
   appointed Chairman of XOMA's Board of Directors.  Mr. Engle
   succeeded John L. (Jack) Castello who had been Chairman, Chief
   Executive Officer and President of XOMA.
 * XOMA continued to advance the development of XOMA 052, its
   proprietary anti-IL-1 beta antibody with multi-indication
   potential.  During the third quarter, the company began two Phase 1
   clinical trials of XOMA 052 in diabetes patients.  The studies are
   designed to assess safety and pharmacokinetics of XOMA 052.  Data
   from the studies will be used to evaluate the development of XOMA
   052 in diabetes and several other possible indications.
 * XOMA granted a license to Pfizer for non-exclusive access to XOMA's
   bacterial cell expression, or BCE, technology.  Pfizer agreed to
   pay XOMA an upfront payment of $30 million in cash, plus future
   milestones and royalties on products developed or manufactured
   using BCE.  The $30 million license fee was recognized in full in
   XOMA's third quarter financials.  The agreement covers products
   currently under development by Pfizer as well as any future
   pipeline products that are derived or made using the BCE
   technology.
 * XOMA initiated a comprehensive review of its corporate strategy for
   building shareholder value.  The review will outline the next steps
   in XOMA's evolution, and focuses on accelerating the growth of
   XOMA's proprietary pipeline, increasing overall productivity and
   continuing cost management.  XOMA expects to begin communicating
   its revised strategy plan this quarter.

Financial Discussion

Revenues

Total revenues for the quarter were $43.1 million, compared with $7.4 million in the third quarter of 2006. Revenues for the first nine months of 2007 more than tripled from $20.5 million in the first nine months of 2006 to $69.5 million.

License and collaborative fee revenues were $31.3 million for the quarter ended September 30, 2007, compared with $0.6 million for the same period of 2006. These revenues include upfront payments related to the outlicensing of our products and technologies and other collaborative arrangements. Contract revenues totaled $7.4 million for the three months ended September 30, 2007, compared with $3.8 million for the same period of 2006, reflecting an increase resulting primarily from increased activities in the company's arrangements with Schering-Plough Research Institute, Takeda Pharmaceutical Company Limited, and AVEO Pharmaceuticals, Inc. Royalties were $4.4 million for the third quarter of 2007 compared with $2.9 million in the third quarter of 2006, reflecting increases in royalty revenues from Genentech's LUCENTIS(r), which began in June of 2006, and Genentech's RAPTIVA(r).

Expenses

XOMA's research and development expense for the third quarter of 2007 totaled $14.6 million, compared with $12.7 million in the same period of 2006. The $1.9 million increase primarily reflects increases in spending on the company's July 2006 contract with NIAID, its contract with AVEO, internal development of XOMA 052, XOMA 629 and collaboration with Schering-Plough and Takeda, offset by a reduction in research and development by a major collaborator of $2.8 million.

General and administrative expense for the three months ended September 30, 2007 was $5.8 million compared with $4.2 million for the same period last year. This increase reflects costs related to the transition of the Company's executive leadership and other items.

Interest expense for the three months ended September 30, 2007 was $1.2 million compared with $1.7 million for the same period of 2006. Interest expense in the 2007 third quarter consisted primarily of $0.4 from the Novartis collaboration facility and $0.8 million on our loan from Goldman Sachs Specialty Lending Holding Inc. ("Goldman Sachs"). XOMA's third quarter 2006 interest expense consisted primarily of $0.3 million on its loan with Novartis and interest of $0.9 million on its outstanding convertible notes. The conversion of this debt to common equity was completed in the first quarter of 2007.

Liquidity and Capital Resources

Cash, cash equivalents and short-term investments at September 30, 2007 totaled $47.6 million compared with $46.4 million at December 31, 2006. The $1.2 million increase includes cash provided by operating activities of $7.4 million, the transfer of $2.7 million from restricted cash and a draw on the Novartis loan of $2.0 million offset by cash used for $4.7 million in principal payments on our Goldman Sachs term loan and cash used in the purchase of fixed assets of $6.5 million. Cash provided by operations during the third quarter of 2007 was $22.6 million compared with cash used in operations of $10.1 million during the third quarter of 2006.

Based on current spending levels, anticipated revenues, collaborator funding, proceeds from our November 2006 term loan and other sources of funding we believe to be available, we estimate that we have sufficient cash resources to meet our anticipated net cash needs through at least 2008. Any significant revenue shortfalls, increases in planned spending on development programs or more rapid progress of development programs than anticipated, as well as the unavailability of anticipated sources of funding, could shorten this period. Progress or setbacks by potentially competing products may also affect our ability to raise new funding on acceptable terms.

Long-term Debt

At September 30, 2007, XOMA had an outstanding principal amount of $30.3 million on the 5-year term loan from Goldman Sachs established in November of 2006, and $18.9 million of long-term debt to Novartis. The long-term debt to Novartis represents XOMA's borrowings under a $50.0 million loan facility established to facilitate XOMA's participation in its collaboration with Novartis.

Guidance Update

XOMA is updating guidance for the full year 2007. The company is raising revenue guidance and expects revenues will grow 165 percent to 175 percent over the full year 2006 revenues of $29.5 million. This compares with previous guidance of growth of 95 percent to 105 percent over full year revenues in 2006.

The company expects R&D expense in 2007 to grow by 30 percent to 35 percent over the R&D expense of $52.1 million in 2006. This revised guidance of R&D expense is an increase of 5 percent on both ends of the range of previous guidance. The company expects that G&A spending will increase approximately 10 percent to 20 percent in 2007 as a result of certain items including costs related to our CEO succession. Previous guidance projected that G&A spending would be relatively flat and approximately equal the $18.1 million spent in 2006. For net interest expense, the company is confirming previous guidance of a reduction by approximately 10 percent from the expense of $11.3 million in 2006.

Finally, the company expects that cash used in operations will significantly decrease from previous guidance due to the $30 million up-front payment related to the recent Pfizer BCE technology license agreement. The company projects that cash used in operations will be less than 15 percent of the $33.3 million used in 2006. Previous guidance projected that cash used in operations would be less than 50 percent of the 2006 amount.
