SOUTH SAN FRANCISCO, CA -- (Marketwire) -- 02/21/13 -- Onyx Pharmaceuticals, Inc. (NASDAQ: ONXX) today reported its financial results for the full year and fourth quarter 2012 and provided a business update.

"This past year was transformational, as Onyx grew from a company with one therapy in two indications to one with three therapies approved in four indications and positive Phase 3 data for another two potential indications," said N. Anthony Coles, M.D., chairman and chief executive officer of Onyx. "We enter 2013 with the architecture for near-term momentum in our business and sustained growth. The successful launch of Kyprolis, Onyx's first wholly-owned product, serves as the foundation of our emerging proteasome inhibitor franchise, and we are committed to investing in a broad Phase 3 clinical development program across all lines of therapy to reach more patients globally. 2013 will be an important year for commercial execution in the United States, while developing select capabilities to expand our business internationally."

Dr. Coles continued, "The second launch of 2012 was Bayer's Stivarga with additional regulatory actions expected this year in the United States, Europe and Japan. Contributions from worldwide sales of Nexavar and royalty revenue from Stivarga provide increasing cash flow to enable the strategic investment in Kyprolis and oprozomib."

Onyx reported total revenue of $362.2 million for the full year 2012 and $127.9 million for the fourth quarter 2012. Onyx reported non-GAAP net loss of $162.9 million, or $2.50 per diluted share, for the full year 2012 and $24.0 million, or $0.36 per diluted share, for the fourth quarter 2012. On a GAAP basis, Onyx reported net loss of $187.8 million, or $2.88 per diluted share, for the full year 2012 and $42.9 million, or $0.64 per diluted share, for the fourth quarter 2012. A description of the non-GAAP calculations and reconciliation to comparable GAAP financial measures is provided in the accompanying table entitled "Reconciliation of GAAP to Non-GAAP Financial Measures."

Revenue
For the full year and fourth quarter of 2012, Onyx reported total revenue of $362.2 million and $127.9 million, respectively, as compared to total revenue of $447.2 million and $237.0 million for the comparable periods in 2011. For the full year and fourth quarter of 2011, total revenue included $160.0 million in contract revenue from collaboration received from the sale of the Japan royalty rights of Nexavar® (sorafenib) tablets.

•Revenue from the Nexavar collaboration agreement for the full year and fourth quarter of 2012 was $288.4 million and $72.9 million, respectively, as compared to $287.0 million and $76.8 million for the comparable periods in 2011. The increase in full year revenue from collaboration is primarily a result of increased Nexavar net sales as recorded by Bayer, excluding Japan, of $861.4 million and $229.1 million for the full year and fourth quarter of 2012, respectively, as compared to $839.9 million and $231.5 million for the full year and fourth quarter of 2011. The increase in full year Nexavar sales was driven by increased sales in the U.S. and demand driven growth in emerging markets including Asia Pacific and Latin America. •Kyprolis® (carfilzomib) for Injection net sales for the full year and fourth quarter of 2012 were $64.0 million and $45.3 million, respectively, representing orders shipped to and received by end customers such as physician offices and hospitals post-approval. The U.S. Food and Drug Administration (FDA) granted accelerated approval of Kyprolis on July 20, 2012. In addition, Onyx recorded deferred revenue of $9.8 million as of December 31, 2012, representing Kyprolis inventory at distributors which has not yet shipped to physician offices and hospitals. •Stivarga® (regorafenib) tablets royalty revenue was $8.3 million and $8.2 million for the full year and fourth quarter of 2012, respectively, following marketing approval by the U.S. FDA on September 27, 2012. Onyx receives a 20% royalty on Bayer's global net sales of Stivarga in human oncology.

Operating Expenses
Non-GAAP cost of goods sold was $1.3 million and $0.8 million for the full year and fourth quarter 2012, respectively. Cost of goods sold related to sales of Kyprolis is not representative of Onyx's future expectations of cost of goods sold because product costs associated with Kyprolis sales in 2012 were charged to research and development expense in periods prior to approval.

Non-GAAP research and development expense was $316.0 million and $80.3 million for the full year and fourth quarter 2012, respectively, compared to $249.1 million and $82.5 million for the same periods in 2011. Higher research and development expense between periods was primarily due to the global development of Kyprolis, particularly the ongoing Phase 3 ASPIRE, FOCUS and ENDEAVOR trials. On a GAAP basis, research and development expense was $325.3 million and $82.6 million for the full year and fourth quarter 2012, respectively, compared to $268.1 million and $84.0 million for the same periods in 2011.

Non-GAAP selling, general and administrative expense was $198.1 million and $68.0 million for the full year and fourth quarter 2012, respectively, compared to $147.8 million and $50.1 million for the same periods in 2011. Higher selling, general and administrative expense between periods was primarily related to hiring of the field force associated with the Kyprolis commercial launch as well as promotional costs. On a GAAP basis, selling, general and administrative expense was $224.2 million and $74.6 million for the full year and fourth quarter 2012, respectively, compared to $168.0 million and $52.6 million for the same periods in 2011.

Onyx recorded contingent consideration expense of $69.2 million and $2.9 million for the full year and fourth quarter 2012, respectively, compared to a benefit of $93.5 million and $116.7 million for the same periods in 2011. The increase in contingent consideration expense for the full year was primarily a result of the accelerated approval of Kyprolis.

Amortization expense for certain acquired intangible assets was $9.3 million and $5.2 million for the full year and fourth quarter 2012, respectively, and reflects the amortization of a portion of the intangible asset, which was acquired in the 2009 acquisition of Proteolix, Inc.

Provision for Income Taxes
Provision for income taxes for the full year 2012 primarily consisted of a $96.8 million non-cash tax benefit to recognize a change in the net deferred tax balance related to the U.S. approval of Kyprolis.

Cash, Cash Equivalents and Marketable Securities
On December 31, 2012, cash, cash equivalents and current and non-current marketable securities were $492.8 million, compared to $668.4 million at December 31, 2011. This decrease was largely due to Kyprolis development and commercialization expenses, partly offset by cash proceeds from the exercise of employee stock options. During January 2013, Onyx raised approximately $352 million in net proceeds from a public offering of 4.4 million shares of common stock.

Non-GAAP Financial Measures
This press release includes the following non-GAAP financial measures: non-GAAP net income (loss), non-GAAP net income (loss) - diluted, non-GAAP net income (loss) per share, non-GAAP net income (loss) per share - diluted, non-GAAP cost of goods sold, non-GAAP research and development expense and non-GAAP selling, general and administrative expense. The following table reconciles these non-GAAP measures to the most comparable financial measures calculated in accordance with GAAP.

Onyx management uses these non-GAAP financial measures to monitor and evaluate our operating results and trends on an on-going basis, and internally for operating, budgeting and financial planning purposes. Onyx management believes the non-GAAP information is useful for investors by offering the ability to better identify trends in our business and better understand how management evaluates the business. These non-GAAP measures have limitations, however, because they do not include all items of income and expense that affect Onyx. These non-GAAP financial measures are not prepared in accordance with, and should not be considered in isolation of, or as an alternative to, measurements required by GAAP. A description of the non-GAAP calculations and reconciliation to comparable GAAP financial measures is provided in the accompanying table entitled "Reconciliation of GAAP to Non-GAAP Financial Measures."

Non-GAAP operating expenses exclude contingent consideration expense (benefit), employee stock-based compensation expense, imputed interest related to the convertible senior notes due 2016, the write-off of certain research and development expenses, equity investment impairment, the impact of the S*BIO termination, lease termination exit costs, amortization of certain acquired intangibles and related tax impact of certain acquired intangible assets.

RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL MEASURES




These non-GAAP financial measures exclude the following items:

(a) Contingent consideration expense (benefit): The effects of contingent consideration expense (benefit) are excluded due to the nature of this charge, which is related to the change in fair value of the liability for contingent consideration in connection with the acquisition of Proteolix; such exclusion facilitates comparisons of Onyx's operating results to peer companies.

(b) Employee stock-based compensation: The effects of employee stock-based compensation are excluded because of varying available valuation methodologies, subjective assumptions and the variety of award types; such exclusion facilitates comparisons of Onyx's operating results to peer companies.

(c) Imputed interest related to the convertible senior notes due 2016: The effects of imputed interest related to the convertible senior notes due 2016 are excluded because this expense is non-cash; such exclusion facilitates comparisons of Onyx's cash operating results to peer companies.

(d) Advance funding to S*BIO and impairment of equity investment in S*BIO: The effects of the termination of the S*BIO collaboration agreement are excluded because they do not relate to the normal and recurring transactions of Onyx's business; such exclusion allows for a better representation of the ongoing economics of the business, facilitates comparison to peer companies and is reflective of how Onyx manages the business.

(e) Proceeds received pursuant to the sale of Jak2 inhibitors by S*BIO: The effects of the proceeds received pursuant to the sale of Jak2 inhibitors by S*BIO are excluded because they do not relate to the normal and recurring transactions of Onyx's business; such exclusion allows for a better representation of the ongoing economics of the business, facilitates comparison to peer companies and is reflective of how Onyx manages the business.

(f) Lease termination exit costs: The effects of lease termination exit costs and reoccupation of facilities are excluded because they represent non-cash items that relate to Onyx's exit from facilities it previously occupied in Emeryville and in South San Francisco, California.

(g) Amortization of certain acquired intangible assets: The effects of amortization of certain acquired intangible assets are excluded because this expense is non-cash; such exclusion facilitates comparisons of Onyx's operating results to peer companies.

(h) Non-cash tax related effect on certain acquired intangible assets: The tax related effect on certain acquired intangible assets is excluded because this expense is non-cash; such exclusion facilitates comparisons of Onyx's operating results to peer companies.

(i) Under the "if-converted" method, interest and issuance costs and potential common shares related to the Company's convertible senior notes were excluded in the computation of diluted per share amounts for the three months ended December 31, 2012 and the years ended December 31, 2012 and 2011 because their effect would be anti-dilutive.
