FOR IMMEDIATE RELEASE

KING PHARMACEUTICALS REPORTS
SECOND QUARTER 2009 FINANCIAL RESULTS

• Strong Cash flow from operations of $101 million

• $152 million in debt repayment

• acceleration of acquisition synergies

BRISTOL, TENNESSEE, August 6, 2009 — King Pharmaceuticals, Inc. (NYSE:KG) announced today that total revenues were $445 million during the second quarter ended June 30, 2009, compared to $397 million in the second quarter of 2008. The Company reported a net income of $38 million and diluted earnings per share of $0.15 during the second quarter of 2009, compared to net income of $41 million and diluted earnings per share of $0.17 in the second quarter of the prior year. Excluding certain special items and recurring non-GAAP adjustments, adjusted net income equaled $80 million and adjusted diluted earnings per share equaled $0.32 during the second quarter ended June 30, 2009, compared to adjusted net income of $87 million and adjusted diluted earnings per share of $0.35 in the second quarter of 2008.

Similar to its financial reporting in prior years, King reports financial results determined in accordance with Generally Accepted Accounting Principles (“GAAP”) and also adjusted financial results. However, beginning with the first quarter of 2009, King’s adjusted financial results exclude the amortization of intangible assets and non-cash imputed interest expense associated with the Company’s $400 million 1¹/4% Convertible Senior Notes, as well as special items. For more information, see the “About Adjusted Financial Results” paragraph below.

Brian A. Markison, Chairman, President and Chief Executive Officer of King, stated, “Today’s announcement of strong second quarter earnings underscores the successful and rapid integration of the Alpharma acquisition.” Mr. Markison continued, “More importantly, we believe we are moving closer to an EMBEDA™ approval and recently defined a clear regulatory path forward for REMOXY^®. We also remain excited about the prospects for ACUROX^®, and look forward to meeting with the FDA next month. We believe that all three of these products represent a potential first in class opioid formulation designed to deter some of the more common forms of misuse and abuse.”

Joseph Squicciarino, King’s Chief Financial Officer, stated, “We continue to execute on our growth strategy for the company and remain on target to deliver results consistent with our previously stated guidance. Of particular importance, the Company repaid a total of $152 million of principal during the second quarter on the $625 million of long-term debt we incurred in connection with the Alpharma acquisition, bringing the total debt repayment thus far to $200 million. Our cash flow from operations was $101 million during the second quarter of 2009

despite $44 million in restructuring payments made during the quarter, and we are on track to achieve $80 million in synergies this year from the Alpharma acquisition. These synergies, achieved earlier than anticipated, will allow us to reduce this year’s selling, general and administrative expense by $20 million to a range of $540 to $560 million.”

As of June 30, 2009, the Company’s cash and cash equivalents totaled approximately $442 million.

Net revenue from branded pharmaceuticals totaled $275 million for the second quarter of 2009, compared to $316 million during the second quarter of 2008. The decrease in revenues was primarily due to the market entry of generic substitutes for ALTACE^® (ramipril) beginning in December 2007.

Net sales of SKELAXIN^â (metaxalone) totaled $102 million during the second quarter of 2009, compared to $107 million during the same period of the prior year.

THROMBIN-JMI^Ò (thrombin, topical, bovine, USP) net sales totaled $49 million during the second quarter of 2009, compared to $64 million during the second quarter of 2008.

Net sales of AVINZA^â (morphine sulfate extended release) totaled $29 million during the second quarter of 2009, compared to $35 million during the second quarter of 2008.

Net sales of FLECTOR^â PATCH (diclofenac epolamine topical patch) 1.3% totaled $39 million during the second quarter of 2009. The Company added FLECTOR^â PATCH as a result of its acquisition of Alpharma on December 29, 2008. As previously reported, the wholesale inventory levels of FLECTOR^â PATCH exceeded King’s normal level as of the end of the fourth quarter of 2008. During the first quarter, wholesale inventory levels were fully adjusted and therefore net sales in the second quarter more closely reflected actual prescription demand.

Revenues from the Animal Health business were $83 million for the second quarter ended June 30, 2009. The Company added the Animal Health business as a result of its acquisition of Alpharma.

King’s Meridian Auto-Injector business contributed revenue totaling $72 million during the second quarter of 2009, compared to $55 million during the second quarter of 2008.

Royalty revenues, derived primarily from ADENOSCAN^Ò (adenosine), totaled $15 million during the second quarter of 2009.

About Adjusted Financial Results

In addition to financial results determined in accordance with Generally Accepted Accounting Principles (“GAAP”), King provides adjusted net earnings and adjusted diluted earnings per share results. These non-GAAP financial measures exclude the effect of amortization of intangible assets and non-cash imputed interest expense associated with the Company’s $400 million 1¹/4% Convertible Senior Notes, as well as special items. Special items are those particular material income or expense items that King considers to be unrelated to the Company’s ongoing, underlying business, non-recurring, or not generally predictable, and include, but are not limited to, merger and restructuring expenses; non-capitalized expenses associated with acquisitions, such as in-process research and development charges and inventory valuation adjustment charges; charges resulting from the early extinguishment of debt; asset impairment charges; expenses of drug recalls; and gains and losses resulting from the divestiture of assets. King believes that providing adjusted financial results enhances the analysis of the Company’s ongoing, underlying business and the analysis of the Company’s financial results when comparing those results to that of a previous or subsequent like period. However, it should be noted that the determination of whether to exclude an item from adjusted financial results involves judgments by King’s management. A reconciliation of adjusted financial results and King’s reported financial results determined in accordance with GAAP is provided below.
