Amgen's Fourth Quarter 2006 Revenue Increased 17% to $3.8 Billion; Full Year 2006 Revenue Increased 15% to $14.3 Billion

THOUSAND OAKS, Calif.--(BUSINESS WIRE)--Jan 25, 2007 - Amgen (NASDAQ:AMGN) reported adjusted EPS, excluding stock option expense and certain other expenses, of $0.90 for the fourth quarter of 2006, an increase of 20 percent compared to $0.75 during the fourth quarter of 2005. Adjusted EPS for the fourth quarter of 2006 includes a 3 cent per share cost for the collaboration with Cytokinetics which was announced earlier this year. Adjusted net income, excluding stock option expense and certain other expenses, increased 14 percent to $1,060 million compared to $928 million in the fourth quarter of 2005. Stock option expense on a per share basis totaled 3 cents and 5 cents in the fourth quarter of 2006 and fourth quarter of 2005, respectively.

Full year 2006 adjusted EPS, excluding stock option expense and certain other expenses, was $3.90 versus $3.20 in 2005, a 22 percent increase. Full year 2006 adjusted net income, excluding stock option expense and certain other expenses, was $4.6 billion versus $4.0 billion in 2005, a 15 percent increase. Stock option expense on a per share basis totaled 14 cents and 19 cents in 2006 and 2005, respectively.

Total revenue increased 17 percent during the fourth quarter of 2006 to $3,835 million versus $3,271 million in the fourth quarter of 2005 and 15 percent for the full year 2006 to $14.3 billion versus $12.4 billion in 2005.

Adjusted EPS and adjusted net income for the fourth quarter and full year 2006 and 2005 exclude stock option expense, certain expenses related to the acquisitions of Immunex, Tularik, Abgenix and Avidia during the applicable time periods and certain other items. These expenses and other items are itemized on the reconciliation tables below. Adjusted EPS including the impact of stock option expense is also itemized on the reconciliation tables below.

On a reported basis and calculated in accordance with U.S. Generally Accepted Accounting Principles (GAAP), Amgen's EPS was $0.71 in the fourth quarter of 2006, an increase of 8 percent compared to $0.66 in the same quarter last year. Net income increased 1 percent to $833 million in the fourth quarter of 2006 versus $824 million in the fourth quarter of 2005. For the full year 2006, Amgen's reported EPS decreased 15 percent to $2.48 from $2.93 in 2005. Full year 2006 net income was $2,950 million versus $3,674 million in 2005, a decrease of 20 percent. The fourth quarter of 2006 and the full year 2006 reported GAAP results were negatively impacted by $130 million and $1.2 billion, respectively, of acquired in-process research and development (R&D) write-offs associated with the acquisitions of Avidia and Abgenix while 2005 included no such impact. Effective Jan. 1, 2006, Amgen began recording expense associated with employee stock options in accordance with Statement of Financial Accounting Standards No. 123R. As a result, reported GAAP results for the fourth quarter of 2006 and the full year 2006 were negatively impacted by $54 million and $233 million, respectively, on a pre-tax basis.

"Amgen had another year of strong revenue and adjusted earnings growth while we invested heavily in our promising pipeline opportunities," said Chairman and CEO Kevin Sharer. "We also expanded our product portfolio with the successful launch of Vectibix(TM) (panitumumab), which offers new hope for patients with colorectal cancer. I expect that we will continue on a solid growth path in 2007 while key products in our pipeline continue to progress."

Product Sales Performance

Total product sales increased 18 percent to $3,737 million in the fourth quarter of 2006 versus $3,168 million in the fourth quarter of 2005. Sales in the United States in the fourth quarter increased 18 percent to $3,101 million versus $2,625 million in the prior year. International sales in the fourth quarter increased 17 percent to $636 million versus $543 million in the prior year. Excluding the impact of foreign exchange, total product sales for the fourth quarter increased 17 percent and international product sales increased 12 percent versus the prior year. For the full year, total product sales were $13,858 million in 2006 versus $12,022 million in 2005, a 15 percent increase. U.S. sales for the full year increased 15 percent to $11,397 million versus $9,892 million in the prior year. International sales for the full year increased 16 percent to $2,461 million versus $2,130 million in the prior year.

Worldwide sales of Aranesp(R) (darbepoetin alfa) increased 27 percent to $1,106 million in the fourth quarter of 2006 versus $873 million during the fourth quarter of 2005. U.S. Aranesp sales in the fourth quarter increased 31 percent to $761 million versus $579 million in the prior year. International Aranesp sales in the fourth quarter increased 17 percent to $345 million versus $294 million in the prior year. Changes in foreign exchange positively impacted fourth quarter sales by $15 million. For the full year, worldwide Aranesp sales were $4,121 million in 2006 versus $3,273 million in 2005, a 26 percent increase. Growth for the fourth quarter and full year was primarily driven by demand, reflecting segment growth and share gains.

Sales of EPOGEN(R) (Epoetin alfa) increased 6 percent to $661 million in the fourth quarter of 2006 versus $626 million in the fourth quarter of 2005. For the full year, EPOGEN sales were $2,511 million in 2006 versus $2,455 million in 2005, a 2 percent increase. Growth for the fourth quarter and full year was primarily driven by underlying demand in the free-standing dialysis clinics. These increases were partially offset by year-over-year increased use of Aranesp in the hospital setting. The Company believes that conversion to Aranesp in the hospital setting stabilized as of the middle of this year. Underlying demand in free-standing dialysis clinics remained consistent with an annual patient population growth of 3-4 percent.

Combined worldwide sales of Neulasta(R) (pegfilgrastim) and NEUPOGEN(R) (Filgrastim), increased 10 percent to $1,024 million in the fourth quarter of 2006 versus $928 million for the fourth quarter of 2005. Combined sales of Neulasta and NEUPOGEN in the United States in the fourth quarter increased 10 percent to $802 million versus $729 million in the prior year. International sales in the fourth quarter increased 12 percent to $222 million versus $199 million in the prior year. Changes in foreign exchange positively impacted fourth quarter sales by $9 million. For the full year, worldwide combined sales of Neulasta and NEUPOGEN were $3,923 million in 2006 versus $3,504 million in 2005, a 12 percent increase. Growth for the fourth quarter and full year was primarily driven by increased demand for Neulasta.

North American sales of Enbrel(R) (etanercept) increased 18 percent to $792 million in the fourth quarter of 2006 versus $674 million in the fourth quarter of 2005. For the full year, ENBREL sales were $2,879 million in 2006 versus $2,573 million in 2005, a 12 percent increase. Growth for the fourth quarter and full year was primarily driven by increased demand in both the Rheumatology and Dermatology segments, and was also driven by favorable discount adjustments of $31 million in the fourth quarter. Growth for the fourth quarter and full year was negatively impacted by share declines versus the prior year in Rheumatology and Dermatology. ENBREL remains the share leader in both segments.

Worldwide sales of Sensipar(R) (cinacalcet HCl) increased 92 percent to $98 million in the fourth quarter of 2006 versus $51 million in the fourth quarter of 2005. For the full year, Sensipar sales were $321 million in 2006 versus $157 million in 2005, a 104 percent increase. Growth for the fourth quarter and full year was driven by demand.

Vectibix was launched in the United States in the fourth quarter of 2006. Vectibix sales for the quarter were $39 million.

Operating Expense Analysis on an Adjusted Basis:

Cost of sales increased 8 percent to $551 million in the fourth quarter of 2006 versus $511 million in the fourth quarter of 2005. The increase for the fourth quarter was primarily driven by increased sales volumes partially offset by lower royalties. For the full year, cost of sales totaled $2,080 million in 2006 and $2,035 million in 2005, an increase of 2 percent. For the full year, cost of sales grew much slower than revenue due to lower royalties as well as a more favorable product mix and cost efficiencies at our factories.

R&D expenses increased significantly to $1,003 million in the fourth quarter of 2006 versus $658 million in the fourth quarter of 2005, an increase of 52 percent. For the full year 2006, R&D expenses were $3,191 million versus $2,302 million in 2005, an increase of 39 percent. Fourth quarter and full year increases were primarily due to higher staff levels and increased funding necessary to support clinical trials for our late-stage programs, including the nine mega-trials (trials with more than 200 sites) initiated in 2006, and the continued expansion of our research and pre-clinical organization to build the capacity to advance more compounds through the clinic.

Selling, general and administrative (SG&A) expenses increased 10 percent to $1,001 million in the fourth quarter of 2006 versus $913 million in the fourth quarter of 2005. For the full year 2006, SG&A expenses totaled $3,234 million compared to $2,792 million in 2005, an increase of 16 percent. Increases for the fourth quarter and full year reflect higher staff and additional infrastructure costs to support the growing organization, in particular our Global Enterprise Resource Planning (ERP) program, and higher Wyeth profit share expenses related to ENBREL sales. Fourth quarter increases were also driven by higher promotion and advertising spending for our marketed products while full year increases were also driven by higher legal costs associated with ongoing litigation.

During the fourth quarter of 2006, adjusted EPS growth of 20 percent exceeded revenue growth of 17 percent by 3 percentage points. EPS leverage for the fourth quarter was principally driven by fewer shares used in the computation of adjusted diluted EPS, a lower adjusted tax rate and higher interest income partially offset by significantly higher R&D investment. The adjusted tax rate was lower due to the retroactive extension of the R&D tax credit and a favorable audit settlement occurring earlier than anticipated. For the full year 2006, adjusted EPS growth of 22 percent exceeded revenue growth of 15 percent by 7 percentage points. Full year EPS leverage was principally driven by fewer shares used in the computation of adjusted diluted EPS, a lower adjusted tax rate due to favorable audit settlements and increased manufacturing in Puerto Rico and higher interest income partially offset by significantly higher R&D investment.

During the fourth quarter of 2006, Amgen repurchased 3.3 million shares at a total cost of $245 million, with full year repurchases totaling 70.2 million shares at a total cost of $5.0 billion. In December 2006, Amgen's Board of Directors authorized a new stock repurchase program of $5.0 billion. The Company currently has $6.5 billion remaining under this and the previously authorized stock repurchase program. Average diluted shares for adjusted EPS in the fourth quarter of 2006 were 1,175 million versus 1,243 million in the fourth quarter of 2005. For the full year 2006, average diluted shares for adjusted EPS were 1,186 million compared to 1,258 million in 2005. Share decreases for the fourth quarter and full year 2006 reflect the Company's aggressive share repurchase program.

Capital expenditures for the fourth quarter of 2006 were approximately $384 million versus $265 million in the fourth quarter of 2005 bringing full year capital expenditures to $1.2 billion in 2006 versus $0.9 billion in 2005. Worldwide cash and marketable securities were $6.3 billion and debt was $9.0 billion at the end of 2006.

2007 Guidance

The Company expects total revenue for 2007 to be in the range of $15.4 to $16.0 billion. Amgen expects 2007 adjusted EPS to be in the range of $4.30 to $4.50, excluding stock option expense, certain expenses related to the acquisitions of Immunex, Tularik, Abgenix and Avidia and certain other items itemized on the reconciliation table below. Amgen expects the per share impact of stock option expense to be in the range of $0.10 to $0.12 in 2007 compared to $0.14 in 2006.

Amgen expects adjusted cost of sales in 2007 to be comparable as a percent of product sales to 2006. The Company expects the adjusted R&D expense growth rate to be in the low teens while the adjusted SG&A growth rate is expected to be lower than 2006. Amgen's expectation for the adjusted tax rate is that it will be slightly lower than 2006, and it expects to maintain its share repurchase program at similar investment levels to 2006.

The Company expects 2007 capital expenditures to increase versus 2006 as it expands its Puerto Rico manufacturing site, builds a new fill/finish and bulk facility in Ireland and continues to expand R&D sites in San Francisco, Seattle and the United Kingdom.

Fourth Quarter Product and Pipeline Highlights

The Company also highlighted progress in research and development, including updates on selected late-stage clinical programs (Vectibix, motesanib diphosphate (AMG 706), Aranesp, Sensipar, denosumab and AMG 531) and the early-stage pipeline.

Vectibix: The Company announced that an interim (12-week) response-rate analysis was performed on schedule in the Panitumumab Advanced Colorectal Cancer Evaluation (PACCE) study, a non-registration-enabling trial evaluating Vectibix in first-line treatment of metastatic colorectal cancer. The primary endpoint of this study is progression free survival, with secondary endpoints of response rate, overall survival and safety. Patients were randomized to treatment with Avastin(R)(bevacizumab) plus chemotherapy with or without Vectibix. Over 1,000 patients have been enrolled in the PACCE study. Response rates in the first 500 patients were similar in the two treatment groups. Additionally, the Company has informed all investigators and regulatory authorities about safety information arising from this planned interim analysis of the PACCE trial. A review of the data by the Independent Data Monitoring Committee (DMC) showed an increased incidence of diarrhea, dehydration and infection when Vectibix was given in combination with bevacizumab and either irinotecan or oxaliplatin-based chemotherapy. These are recognized toxicities that are specifically noted in the Vectibix U.S. prescribing information and panitumumab Investigator's Brochure. The PACCE study is continuing in accordance with the DMC recommendation. The Company anticipates presenting the results of an interim analysis of safety and efficacy (including progression free survival after 25 percent of events have accrued) at scientific meetings in the first half of 2007. The risks and benefits of using panitumumab in combination with chemotherapy and bevacizumab have yet to be established.

The Company also provided an update on its studies for the treatment of head and neck cancer and adjuvant colorectal cancer (CRC) with Vectibix. The Company has decided to initiate two Phase 2 studies addressing the safety and efficacy of Vectibix in the first-line treatment of locally advanced squamous cell cancer of the head and neck (SCCHN), and to defer the previously announced Phase 3 study in the same setting. Additionally, the previously announced Phase 3 study in first-line metastatic SCCHN has been delayed by one to two quarters from the timeline previously disclosed to permit improvements in the study design and execution.

In the adjuvant CRC setting, the Company plans to conduct a second Phase 3 study in addition to its co-operative Phase 3 study with the National Surgical Adjuvant Breast and Bowel Project (NSABP) group previously announced.

Motesanib diphosphate (AMG 706): The Company announced that six-month data from the Phase 2 study of motesanib diphosphate (AMG 706) for the treatment of locally advanced or metastatic thyroid cancer patients became available. Motesanib diphosphate was clearly active in this setting, as judged by response rate criteria, with an acceptable safety profile. Detailed analyses of these data will be shared with regulatory agencies in the next few months, and will be presented at scientific meetings shortly thereafter.

The Company also provided an update on their investigation of cholecystitis and enlargement of the gall bladder previously observed in patients who had received motesanib diphosphate. The Company continues to gather data on this issue. Based on data gathered to this point, the Company believes these events are manageable. The Company will review data with regulatory agencies in the coming months. Ongoing studies have continued subject to protocol amendments to ensure that physicians are aware of the need to manage gall bladder enlargement or cholecystitis, should these occur.

Because of increasing comfort with the safety profile of motesanib diphosphate, the Company has re-launched its head-to-head Phase 2 study of this agent versus Avastin(R) in the treatment of metastatic breast cancer. A second head-to-head Phase 2 study against Avastin(R) in non-small cell lung cancer (NSCLC) is now under way. Additionally, the Company announced plans for a Phase 3 study in NSCLC which is expected to initiate in the second half of 2007. This study is projected to enroll 1,250 patients.

Aranesp: During the quarter, the Company completed an initial analysis of its Anemia of Cancer Phase 3 study. This study was a randomized, double-blind, placebo-controlled trial of Aranesp administered every four weeks in patients with active cancer not receiving chemo- or radiation therapy. All patients entering the study had anemia (Hb less than or equal to 11 g/dL) in the setting of active cancer (i.e., they were not in remission). These criteria identify a subset of patients with an especially grave prognosis. At the end of 16 weeks, there was no statistically significant difference in the frequency of transfusions in the population receiving placebo injections as opposed to those receiving Aranesp. There was a statistically significant increased risk of death in the Aranesp-treated group, however, the overall safety profile did not identify any other unexpected safety concerns. Since this study was not designed as a survival study, an effect of imbalances in potentially important prognostic factors that were present at baseline cannot be excluded. Nevertheless, in this population of patients with active cancer, not in remission and not receiving chemotherapy, who have unexplained anemia, the Company concluded that the risk/benefit ratio for Aranesp use is at best neutral and perhaps negative. Two other large, placebo-controlled studies, TREAT (Trial to Reduce cardiovascular Events with Aranesp Therapy), which examines outcomes in anemic patients with renal insufficiency, and RED-HF (Reduction of Events with Darbepoetin alfa in Heart Failure) Trial(TM), which examines the utility of Aranesp for the treatment of heart failure, are continuing as planned.

Sensipar: The Company has elected not to file for the expanded indication of Sensipar for the treatment of secondary hyperparathyroidism in the setting of chronic renal insufficiency based on a recently completed Phase 3 study. In this case, all efficacy endpoints were positive, supporting the ability of Sensipar to reduce parathyroid hormone levels in these patients. However, the incidence of asymptomatic hypocalcemia in Sensipar-treated patients was felt to be incompatible with routine use of Sensipar in this setting. Additional analyses are underway which may permit the identification of a dosing regimen that would allow the use of Sensipar in this patient group.

Denosumab: The Company confirmed that its Postmenopausal Osteoporosis (PMO) and Hormonal Ablation Bone Loss Trial (HALT) programs are on track. Additionally, enrollment has completed in the Company's Phase 3 study to compare the efficacy of treatment with denosumab versus alendronate in postmenopausal women with low bone mineral density. The study has enrolled 1,100 patients. Additionally, enrollment has completed in a Phase 2 study in multiple myeloma. The study has enrolled 100 patients.

AMG 531: Both Phase 3 studies of AMG 531 in immune thrombocytopenic purpura (ITP) have been completed. In the first of these studies, patients with ITP despite prior splenectomy were randomized to receive either placebo or AMG 531 over a 6 month period. Review of the data from this study revealed a very favorable efficacy and safety profile, with all endpoints successfully met. The Company expects to review data from a second Phase 3 study in pre-splenectomy ITP patients during the first quarter of 2007. Pending positive results from this study, the Company announced that they expect to file for approval of AMG 531 in the ITP indication in both the U.S. and Europe in 2007.

Early-Stage Pipeline Update: The Company announced it continues to make progress advancing its early-stage pipeline. Since the start of 2006, twelve new molecules, including four in oncology, two for diabetes, two for inflammation, one for idiopathic pulmonary fibrosis, one for cancer cachexia, one for asthma and one for Alzheimer's disease have been advanced into clinical development. Additionally, five new molecules, one for bone loss, one for inflammation, one for diabetes, one for pain and one for psoriasis have entered the clinic.

Outreach Update: As previously announced, the Company completed its acquisition of Avidia, a privately held biopharmaceutical company that discovers and develops a new class of human therapeutic known as Avimer(TM) proteins. The transaction provides the Company with Avidia's lead product candidate, an inhibitor of interleukin 6 (IL-6) for the treatment of inflammation and autoimmune diseases, which is in Phase 1 clinical trials.

The Company also entered into a strategic collaboration with Cytokinetics Incorporated to discover, develop and commercialize novel small-molecule therapeutics that activate cardiac muscle contractility for potential applications in the treatment of heart failure. In addition, the Company obtained an option to participate in future development and commercialization of Cytokinetics' lead drug candidate arising from this program, CK-1827452, which recently completed two Phase 1 clinical trials. The collaboration is worldwide, excluding Japan.

Notes to Reconciliation of GAAP Earnings to "Adjusted" Earnings -

 Excluding Stock Option Expense

(In millions, except per share data)

(Unaudited)


 (1) To exclude the impact of stock option expense recorded in

      accordance with Statement of Financial Accounting Standards

      ("SFAS") No. 123R. Effective January 1, 2006, Amgen adopted SFAS

      No. 123R and elected not to apply this new accounting standard

      to its prior years' financial statements. Prior to such date,

      Amgen disclosed in the notes to its financial statements what

      the related expense and impact to earnings per share (EPS) would

      have been (i.e., on a pro forma basis) had it elected to expense

      the fair value of employee stock options in accordance with SFAS

      No. 123. For the three months and year ended December 31, 2006,

      the total pre-tax expense for employee stock options in

      accordance with SFAS No. 123R was $54 million and $233 million,

      respectively. For the three months and year ended December 31,

      2005, the total pro forma pre-tax expense for employee stock

      options in accordance with SFAS No. 123 was $74 million and $337

      million, respectively.


     Adjusted EPS including the impact of stock option expense for the

      three months and year ended December 31, 2006 and 2005 was as

      follows:




                            Three Months Ended        Year Ended

                           --------------------- ---------------------


     "Adjusted" EPS,

 (2) To exclude merger related expenses incurred due to the Abgenix,

      Inc. ("Abgenix") acquisition, primarily related to incremental

      costs associated with retention and/or recording inventory

      acquired at fair value which is in excess of our standard cost.


 (3) To exclude the ongoing, non-cash amortization of the intangible

      asset, XenoMouse(R) technology, acquired with the Abgenix

      acquisition. The non-cash charge for 2007 is currently estimated

      to be approximately $64 million, pre-tax.


 (4) To exclude merger related expenses incurred due to the Tularik

      Inc. ("Tularik") acquisition, primarily related to incremental

      costs associated with retention and/or integration.


 (5) To exclude merger related expenses incurred due to the Avidia,

      Inc. ("Avidia") acquisition, primarily related to incremental

      costs associated with integration.


 (6) To exclude the non-cash expense associated with writing off the

      acquired in-process research and development related to the

      Avidia acquisition.


 (7) To exclude the ongoing, non-cash amortization of acquired

      intangible assets, primarily ENBREL, related to the Immunex

      Corporation ("Immunex") acquisition. The non-cash charge for

      2007 is currently estimated to be approximately $296 million,

      pre-tax.


 (8) To exclude the non-cash expense associated with writing off the

      acquired in-process research and development related to the

      Abgenix acquisition.


 (9) To exclude the impairment of a non-ENBREL related intangible

      asset previously acquired in the Immunex acquisition.


(10) To exclude the impact of writing off the cost of a semi-completed

      manufacturing asset that will not be used due to a change in

      manufacturing strategy.


(11) To exclude the impact to the Company of its share of the third-

      party reimbursements received by Kirin-Amgen, Inc. related to

      the Genentech, Inc. ("Genentech") legal settlement in August

      2003.


(12) To exclude the impact of legal settlements incurred, net of

      amounts previously accrued, primarily related to settling a

      patent legal proceeding.


(13) To exclude the net gain realized on the termination of a

      manufacturing agreement with Genentech for the production of

      ENBREL at Genentech's manufacturing facility in South San

      Francisco.

      were immediately charged to interest expense as a result of

      certain holders of the convertible notes due in 2032 exercising

      their March 1, 2005 put option and the related convertible notes

      being repaid in cash.

(A)  Dilutive securities used to compute "Adjusted" diluted earnings

      per share for the three months and year ended December 31, 2006

      were computed exclusive of the methodology used to determine

      dilutive securities under SFAS No. 123R.


(B)  On May 6, 2005 and on several subsequent dates, in connection

      with an exchange offer, we modified the terms of substantially

      all of our convertible notes due in 2032. As a result, if

      converted, these convertible notes would be settled in 1) cash

      equal to the lesser of their accreted value at the conversion

      date or the conversion value, as defined, and 2) shares of

      common stock, if any, to the extent the conversion value exceeds

      the accreted value. Accordingly, the convertible notes due in

      2032, as modified, do not impact diluted earnings per share

      under the "if-converted" method; rather, they impact diluted

      earnings per share under the treasury stock method only to the

      extent that the conversion value exceeds the accreted value

      during any reporting period, because such difference, if any,

      could be potentially settled in shares of common stock.
