    "We are optimistic about our financial performance in 2009 and are focused
on making denosumab a success," said 
Adjusted EPS and adjusted net income for the second quarter of 2009 and 2008 exclude, for the applicable periods, stock option expense, certain expenses related to acquisitions, restructuring charges, the income tax benefit as a result of resolving certain non-routine transfer pricing issues with the Internal Revenue Service (IRS), loss accruals for settlements of certain commercial legal proceedings and certain other items. In addition, adjusted EPS and adjusted net income for the second quarter of 2009 and 2008 exclude the incremental non-cash interest expense resulting from a change in accounting for convertible debt as discussed below. These expenses and other items are itemized on the attached reconciliation tables.

Product Sales Performance
    During the second quarter of 2009, total product sales decreased 2 percent
to 
    Worldwide sales of Aranesp  (darbepoetin alfa) decreased 16 percent to
    Sales of EPOGEN  (Epoetin alfa) increased 3 percent to 
    Combined worldwide sales of Neulasta  (pegfilgrastim) and NEUPOGEN
(Filgrastim) decreased 4 percent to 
    Sales of Enbrel  (etanercept) increased 7 percent in the second quarter of
2009 to 
    Worldwide sales of Sensipar  (cinacalcet) increased 11 percent to 
    Vectibix  (panitumumab) sales for the second quarter of 2009 were 
    Operating Expense Analysis on an Adjusted Basis:
        Cost of sales increased 3 percent to $527 million  in the second
        quarter of 2009 versus $512 million  in the second quarter of 2008
        primarily driven by higher fill and finish costs resulting from lower
        utilization at our manufacturing facility in Puerto Rico .
        Research & Development (R&D) expenses were $657 million  in the second
        quarter of 2009 versus $779 million  in the second quarter of 2008, a
        decrease of 16 percent.  This decrease is in part due to the $100
        million  expense in the second quarter of 2008 resulting from the
        upfront payment associated with the Kyowa Hakko collaboration.  The
        remainder of the expense decrease was primarily driven by lower
        clinical trial costs for denosumab and Vectibix registrational
        studies, partially offset by a $50 million  expense in the second
        quarter of 2009 resulting from the payment to obtain an exclusive
        license to Cytokinetics'  cardiac contractility program.
        Selling, General & Administrative (SG&A) expenses were relatively
        unchanged at $891 million  in the second quarter of 2009 versus $894
        million  in the prior year.  Lower staff related expenses, lower
        litigation expenses, and lower enterprise resource planning (ERP)
        system related expenses were offset by higher promotional expenses for
        marketed products, increased spending for activities in preparation
        and anticipation of approval and launch of denosumab, and higher
        expenses associated with the Wyeth  profit share due to higher ENBREL
        sales.
        Excluding expenses associated with the Wyeth  profit share of $301
        million  and $283 million  in the second quarter of 2009 and 2008,
        respectively, adjusted SG&A expenses in the second quarter of 2009
        decreased 3 percent versus the same quarter last year.
    The adjusted tax rate in the second quarter of 2009 was 18.1 percent
compared to 22.2 percent in the second quarter of 2008.  The decrease in the
adjusted tax rate is primarily due to increased bulk manufacturing and profits
in 
Average diluted shares for adjusted EPS in the second quarter of 2009 were 1,016 million versus 1,080 million in the second quarter of 2008.
    Capital expenditures for the second quarter of 2009 were approximately

    Second Quarter Product and Pipeline Update
    The Company provided updates on selected products and clinical programs.
Denosumab: The Company discussed the previously announced results of its pivotal, Phase 3, head-to-head study where denosumab demonstrated superiority versus Zometa (zoledronic acid) in the treatment of bone metastases in advanced breast cancer patients.
    Vectibix:  The Company discussed the approval of revisions to the U.S.
prescribing information for the epidermal growth factor receptor (EGFr) class
of antibodies, including Vectibix by the 
    Motesanib:  The Company indicated that enrollment has resumed for the
Phase 3 MONET1 trial evaluating motesanib in combination with paclitaxel and
carboplatin for the first-line treatment of advanced non-small cell lung
cancer (NSCLC). The Company also noted that the data from Phase 2 study
evaluating motesanib in combination with chemotherapy or bevacizumab in
combination with chemotherapy will be presented at the World Conference on
Lung Cancer. Motesanib is part of a broad co-development program between 
    AMG 423:  The Company noted it exercised its option to the worldwide
rights (excluding 
Emerging Pipeline: The Company provided an update on several of its clinical programs:
AMG 102: In Phase 2 studies, limited efficacy was seen in glioblastoma multiforme and renal cell carcinoma when AMG 102 was administered in monotherapy, but the effect size was not large enough to warrant moving forward with late-stage studies in these indications. Phase 2 combination studies with AMG 102 in the gastric, prostate, mCRC, and small cell lung cancer settings continue.
    Dulanermin:  The Company has received a preliminary report on the Phase 2
NSCLC study with dulanermin (rhApo2L/TRAIL), which is being developed in
collaboration with 
AMG 222: The Company has received results from a Phase 2a study of AMG 222 in patients with type 2 diabetes. The results support continued Phase 2 development of AMG 222.
AMG 785: The Company announced that it is in the process of initiating Phase 2 studies of AMG 785 (Sclerostin) in fracture healing and postmenopausal osteoporosis

Forward-Looking Statements
    This news release contains forward-looking statements that involve
significant risks and uncertainties, including those discussed below and
others that can be found in our Form 10-K for the year ended 
No forward-looking statement can be guaranteed and actual results may differ materially from those we project. The Company's results may be affected by our ability to successfully market both new and existing products domestically and internationally, clinical and regulatory developments (domestic or foreign) involving current and future products, sales growth of recently launched products, competition from other products (domestic or foreign) and difficulties or delays in manufacturing our products. In addition, sales of our products are affected by reimbursement policies imposed by third-party payors, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international trends toward managed care and health care cost containment as well as U.S. legislation affecting pharmaceutical pricing and reimbursement. Government and others' regulations and reimbursement policies may affect the development, usage and pricing of our products. Furthermore, our research, testing, pricing, marketing and other operations are subject to extensive regulation by domestic and foreign government regulatory authorities. We or others could identify safety, side effects or manufacturing problems with our products after they are on the market. Our business may be impacted by government investigations, litigation and product liability claims. Further, while we routinely obtain patents for our products and technology, the protection offered by our patents and patent applications may be challenged, invalidated or circumvented by our competitors. We depend on third parties for a significant portion of our manufacturing capacity for the supply of certain of our current and future products and limits on supply may constrain sales of certain of our current products and product candidate development. In addition, we compete with other companies with respect to some of our marketed products as well as for the discovery and development of new products. Discovery or identification of new product candidates cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate will be successful and become a commercial product. Further, some raw materials, medical devices and component parts for our products are supplied by sole third-party suppliers.

      (a)  Effective January 1, 2009 , we adopted FSP APB 14-1, which changed
           the method of accounting for our convertible notes. In addition, as
           required, we revised our previously reported financial statements
           to retrospectively apply this change in accounting to prior
           periods. Under this new method of accounting, the debt and equity
           components of our convertible notes are bifurcated and accounted
           for separately.  The equity components of our convertible notes are
           included in Stockholders' equity in our Condensed Consolidated
           Balance Sheets with a corresponding reduction in the carrying
           values of our convertible notes as of the date of issuance or
           modification, as applicable.  The reduced carrying values of our
           convertible notes are being accreted back to their principal
           amounts through the recognition of non-cash interest expense. This
           results in recognizing interest expense on these borrowings at
           effective rates approximating what we would have incurred had we
           issued nonconvertible debt with otherwise similar terms.
           In connection with applying this new accounting to prior periods,
           we recorded $58 million  and $115 million  of additional non-cash
           interest expense in the three and six months ended June 30, 2008 ,
           respectively. As a result, our previously reported results of
           operations calculated in accordance with GAAP have been revised for
           the three and six months ended June 30, 2008 , as follows:

    (a) As discussed in more detail above in the notes to the Reconciliation
        of GAAP Earnings to "Adjusted" Earnings, effective January 1, 2009 , we
        adopted FSP APB 14-1, which changed the method of accounting for our
        convertible notes. In addition, as required, we revised our previously
        reported financial statements to retrospectively apply this change in
        accounting to prior periods. As a result, our previously reported
        Consolidated Balance Sheet as of December 31, 2008  has been revised as
        follows:
                                               December 31, 2008
                              ----------------------------------------------
                              As originally     Effect of FSP APB
                                reported              14-1         "Revised"

      (1) The reduction in Convertible notes reflects the bifurcation of the
          equity components of our convertible notes partially offset by the
          accretion of the reduced carrying values resulting from the
          recognition of non-cash interest expense through December 31, 2008 .
      (2) The increase in Other non-current liabilities reflects the impact of
          deferred income taxes.
      (3) The increase in Stockholders' equity reflects the addition of the
          equity components of our convertible notes, partially offset by (i)
          non-cash interest expense recognized through December 31, 2008 
          related to the accretion of the reduced carrying values of our
          convertible notes and (ii) the impact of deferred income taxes.
