Ligand Pharmaceuticals Announces Fourth Quarter Results

Conference Call Begins at 4:30 p.m. Eastern Time Today

SAN DIEGO--

Ligand Pharmaceuticals Incorporated (NASDAQ:LGND) today announced financial results for the three and 12 months ended December 31, 2006, and reviewed business highlights of the fourth quarter of 2006 and early 2007.

Financial Results

The Company sold its commercial oncology products in October 2006. The results of operations related to the oncology products have been reflected as discontinued operations for all reporting periods discussed below.

For the fourth quarter of 2006, total revenues were $34.1 million, compared with total revenues of $35.7 million in the fourth quarter of 2005. Net product sales in the quarter were also $34.1 million, compared with net product sales of $33.4 million in the prior-year fourth quarter. Total revenues in 2006 were $141.0 million, compared with total revenue of $123.0 million in 2005. Net product sales were $137.0 million in 2006, compared with net product sales of $112.8 million in 2005.

As a result of the sale of the Company's commercial oncology products in the fourth quarter of 2006, and the sale of AVINZA(R) in February 2007, Ligand expects that revenue in 2007 will be driven primarily by royalty payments related to sales of AVINZA.

Operating expenses in the fourth quarter of 2006 were $32.4 million, compared with operating expenses of $37.5 million in the fourth quarter of 2005. Operating expenses in 2006 were $181.8 million (excluding a co-promotion termination charge of $131.1 million), compared with operating expenses of $144.9 million in 2005.

In accordance with the corporate restructuring announced in January 2007, the Company's full-time workforce will be reduced by approximately 76% and the majority of commercial operations have been eliminated.

Net income in the fourth quarter of 2006 was $141.4 million, or $1.61 per diluted share, compared with a net loss of $2.8 million, or $0.04 per share, in the comparable 2005 quarter. Income from continuing operations in the fourth quarter of 2006 was $40.6 million, or $0.42 per diluted share, compared with a loss from continuing operations of $3.7 million, or $0.05 per share, in the comparable 2005 quarter. Income from discontinued operations in the fourth quarter of 2006 was $100.7 million, or $1.00 per diluted share, compared with income from discontinued operations of $1.0 million, or $0.01 per share, in the comparable 2005 quarter.

The net loss in 2006 was $31.7 million, or $0.39 per share, compared with a net loss of $36.4 million, or $0.49 per share, in 2005. Loss from continuing operations in 2006 was $135.9 million, or $1.69 per share, compared with a loss from continuing operations of $31.5 million, or $0.43 per share, in 2005. Income from discontinued operations in 2006 was $104.1 million, or $1.30 per share, compared with a loss from discontinued operations of $4.9 million, or $0.06 per share, in 2005.

As of December 31, 2006, Ligand had cash, cash equivalents, short-term investments and restricted cash of $212.5 million. As of February 28, 2007, Ligand had approximately $415 million of unrestricted cash and investments. Additionally, there is $35.0 million of cash held in escrow accounts following the sales of AVINZA and our oncology product line to support potential indemnification claims by the purchasers of those assets. To the extent not utilized, the escrowed funds will become available at varying dates starting in April 2007 through February 2008. The increase in cash since the end of 2006 is due to the closing of the sale of AVINZA to King Pharmaceuticals on February 26, 2007.

"During the fourth quarter of 2006 and into early 2007, we took several critical steps to restructure Ligand into a highly focused R&D and royalty-driven biotech company," said John L. Higgins, President and Chief Executive Officer. "The extent of the Company's transformation is truly revolutionary, and our new business model and highly disciplined operating plan are designed to deliver value to shareholders. Through the sale of AVINZA and of our oncology product line, we now have significant financial resources to continue the development of our proprietary programs and to consider returning cash to our shareholders through a combination of a dividend and share repurchase."

Fourth Quarter and Early 2007 Highlights

Business highlights of the fourth quarter of 2006 and early 2007 include the following:

    --  In March 2007, the Company announced changes to the board of
        directors including naming John L. Higgins, Todd C. Davis,
        Elizabeth M. Greetham and David M. Knott as directors; and the
        resignation of directors John Groom, Irving S. Johnson, Ph.D.,
        Daniel Loeb, Carl C. Peck, M.D. and Brigette Roberts, M.D.
        Additionally, director John W. Kozarich was named chairman of
        the board, replacing Henry F. Blissenbach, who remains a
        director.

    --  In February 2007, Ligand completed the sale of AVINZA
        (morphine sulfate extended release capsules) and associated
        assets to King Pharmaceuticals, Inc. in exchange for cash and
        royalties. Ligand received $280.4 million in cash, which
        represents the purchase price of $246.3 million, net of
        certain inventory adjustments of $18.7 million and less $15.0
        million placed into escrow, plus $49.1 million in
        reimbursement of payments previously made to Organon and
        others.

    --  In January 2007, Ligand announced a restructuring including
        the elimination of approximately 204 positions across all
        functional areas. Associated with the restructuring, several
        executive officers agreed to step down including the Company's
        Chief Financial Officer, Chief Scientific Officer and General
        Counsel.

    --  In January 2007, John L. Higgins joined the Company as Chief
        Executive Officer, President and in March 2007 was named a
        member of its board of directors.

    --  In November 2006, Ligand announced initiation of clinical
        trials for LGD-4665, an oral, small-molecule drug that mimics
        the activity of thrombopoietin (TPO), a growth factor that
        promotes growth and production of blood platelets.

    --  In November 2006, noteholders of Ligand's outstanding 6%
        convertible subordinated notes, in the aggregate principal
        amount of $128.2 million, converted all of the notes into 20.8
        million shares of common stock. Accrued interest and
        unamortized debt issue costs related to the converted notes of
        $0.2 million and $1.0 million, respectively, were recorded as
        additional paid-in capital. Ligand currently has approximately
        101.0 million shares outstanding.

    --  In October 2006, Ligand completed the sale of its oncology
        product line to Eisai Co., Ltd. (Tokyo) and Eisai Inc. (New
        Jersey) for $205.0 million. Of this, $185.0 million was
        received in cash and $20.0 million was placed into escrow. The
        sale included Ligand's four marketed oncology drugs ONTAK(R)
        (denileukin diftitox), Targretin(R) (bexarotene) capsules,
        Targretin(R) (bexarotene) gel 1% and Panretin(R)
        (alitretinoin) gel 0.1%.

    Program Update

The Company also provided the following update on the status and outlook of its key proprietary and partnered development programs.

    Proprietary Program Highlights:

    --  LGD-4665, oral thrombopoietin (TPO) mimetic; as noted above, a
        Phase I clinical trial began in November 2006; the trial is
        expected to be completed in the fourth quarter of 2007.

    --  SARMs (selective androgen receptor modulators); as part of the
        alliance with TAP, the company has exercised options for
        development of certain compounds, and is engaged in
        preclinical research at this time. Ligand anticipates
        advancing its lead drug candidate, LGD-3303, into clinical
        studies in 2008.

    --  SGRMs (selective glucocorticoid receptor modulators): Although
        the overall program will continue to advance, the Company has
        determined not to pursue further development of LGD-5552, as
        Good Laboratory Practice studies failed to demonstrate desired
        preclinical safety characteristics. The Company expects to
        optimize other potential drug candidates to advance to
        clinical studies.

    Partnered Program Highlights:

    --  TPO Mimetics: Ligand's partner GlaxoSmithKline has completed a
        Phase II/III trial and initiated another Phase III trial with
        eltrombopag (Promacta) for idiopathic thrombocytopenic
        purpura. GlaxoSmithKline plans to initiate a Phase III trial
        in 2007 for hepatitis C.

    --  SERMs (selective estrogen receptor modulators): Ligand's
        partner Wyeth, in the fourth quarter, reported positive Phase
        III trial data for bazedoxifene (Viviant) for osteoporosis,
        and bazedoxifene CE (Aprela) for menopause. Bazedoxifene
        (Viviant) currently has a PDUFA date in April 2007, and an NDA
        filing for bazedoxifene CE (Aprela) is expected in late 2007.

    --  SARMs (selective androgen receptor modulators): Ligand's
        partner TAP is continuing its Phase I trial with the LGD-2941
        program for osteoporosis and frailty.
