US Oncology Reports First Quarter 2010 Operating Results

THE WOODLANDS, TX, May 6, 2010 – US Oncology, Inc. (“US Oncology” or “the Company”), reported revenue growth in the first quarter of 2010 of 4.5 percent to $880.5 million from $842.6 million in the same period in 2009. Adjusted EBITDA of $55.2 million in the first quarter of 2010 increased slightly from $55.1 million in the same period in 2009 (see definition of Adjusted EBITDA in “Discussion of Non-GAAP Information” in this release).

Additional highlights for the first quarter are as follows:

First Quarter 2010 Highlights vs 2009

• New cancer patients per day increase of 2.7 percent

• Daily radiation treatments/diagnostic scans increase of 2.0 percent

• Total physicians of 1,338 in the network at March 31, 2010, or 9.0 percent growth

• Clinical trials open to enrollment increased to 88 trials from 71 trials

• Accounts receivable days outstanding reduced to 32 days from 34 days

• Days inventory on hand reduced to 5.5 days from 8.5 days

Chairman and Chief Executive Officer Bruce Broussard stated: “Our operating results from the quarter were in line with our internal expectations, considering our expansion plan. Our investments in sales and marketing are based on our belief that we have significant growth opportunities resulting from pressures on the fragmented oncology market, combined with our information, technology and payer capabilities.

We added 13 people to our sales team this quarter. Although early in the sales cycle, we are encouraged by the receptivity of our more flexible offering through the United Network of US Oncology, which includes a strong emphasis on reimbursement for quality care through our Innovent Oncology service. This quarter we add 28 physicians and as of the end of April we had 42 physicians who have signed contracts and are expected to start within 120 days.

Complementing our physician sales force expansion is our recent investment in a national branding campaign. On May 3, we launched our “United” campaign. The campaign is designed to increase patient and referring physician awareness of the significant benefits of receiving care through a practice affiliated

1

with the United Network of US Oncology. These benefits include access to our clinical research, physician collaboration, evidence-based medicine guidelines, and protected drug supplies. This campaign supports the “United in Healing” local practice campaign we launched last year, and directs people to our redesigned www.usoncology.com website, which now includes rich, patient-focused content, including links to our recently acquired CURE magazine and NexCura Cancer Profiler. The campaign includes placement in five major publications, National Public Radio (“NPR”), 20 trade journals, plus strategically placed online marketing and search engine optimization.”

Broussard continued, “In addition to our physician sales force, we expanded our Healthcare Informatics sales team from 4 to 9, which contributed to a 74 percent increase in our March pipeline as compared to the prior month. The expansion of our clinical analytics team, combined with proprietary clinical information from our electronic health record system, iKnowMed™, allows us to develop strong brand awareness around our clinical analysis capabilities. This is evidenced through our nine abstracts to be presented at three major medical conferences, including the 46^th Annual American Society of Clinical Oncology (“ASCO”).

We continue to maintain our focus on operational excellence. During a quarter of weather problems leading to less operating days, we continued to deliver solid operating and working capital performance. Radiation treatments and diagnostic scans increased 2.0% on a same store basis combined with an increase in productivity as measured by labor expenses per RVU, and a decrease in accounts receivable days outstanding and days of inventory on hand from 34 to 32 and 8.5 to 5.5, respectively.

We are very excited about the future. We have developed a strong competency in clinical information, comparative effectiveness and operational excellence. The healthcare industry is demanding quality reimbursement with improved efficiency as offered through our Innovent Oncology service, and our increased brand awareness and sales footprint, combined with flexible offerings, should provide less-capital intensive growth and improved value proposition to all of our customers.”

Medical Oncology Services

Medical oncology services revenue increased by $13.2 million, or 2.3 percent, to $595.1 million in the first quarter of 2010 as compared to the same period in 2009 despite inclement weather reducing patient volumes and negatively impacting revenues and EBITDA by approximately $17 million and $1 million, respectively. The revenue growth reflects higher medical oncology visits due primarily to additional medical oncologists affiliated through Comprehensive Strategic Alliance (“CSA”) arrangements and increased revenue per patient visit due to a changing mix in services provided by these physicians. Adjusted EBITDA increased to $18.0 million from $16.6 million, or by 8.4 percent, primarily due to earnings associated with revenue growth and an increase in drug margins in the current period from the conversion of Eloxatin to generic status.

2

As generic drugs are introduced to the market, earnings temporarily increase because drug costs decline significantly but reimbursement remains at the branded price for a period of months. However, after reimbursement adjusts, earnings with respect to a generic drug are typically significantly lower than the earnings from a branded pharmaceutical. Although use of generic drugs ultimately results in lower earnings, we support the conversion to generic products because of our dedication to cost-effective care.

Cancer Center Services

Cancer center services revenue increased by $6.0 million, or 6.5 percent, to $98.3 million in the first quarter of 2010 as compared to the same period in 2009. Adjusted EBITDA increased by $2.2 million, or 7.0 percent, to $33.5 million in the first quarter of 2010 as compared to the same period in 2009. These increases reflect a growing network of oncologists and investments in radiation and diagnostic equipment resulting in higher radiation treatment and diagnostic scan volumes which more than offset the impact of inclement weather in the current quarter which negatively impacted revenue and EBITDA by approximately $3 million and $1 million, respectively. In the first quarter of 2010, our network operated 127 linear accelerators, 39 positron emission tomography systems (“PET”) and 67 computed tomography systems (“CT”), which represents increases of 7 units, 1 unit and 4 units, respectively, over the first quarter of 2009. The revenue and Adjusted EBITDA increases also reflect a continued shift toward advanced targeted radiation therapies which are reimbursed at higher rates.

Pharmaceutical Services

Pharmaceutical services revenue in the first quarter of 2010 increased by $40.6 million, or 7.0 percent, to $618.2 million as compared to the same period in 2009. The revenue increase is primarily due to 96 additional medical oncologists affiliated through CSA and Targeted Physician Services (“TPS”) arrangements since the first quarter of 2009. Pharmaceutical services Adjusted EBITDA was $22.5 million for the first quarter of 2010 compared to $22.4 million in the same period of 2009. The EBITDA increase associated with revenue growth and higher distribution performance and service fees was offset by investments supporting our United Network strategy and lower margins under our TPS arrangements as expected.

Research and Other Services

Research and other services revenue in the first quarter of 2010 was $18.4 million, a decrease of $0.9 million compared to the same period in 2009. Adjusted EBITDA in the first quarter of 2010 was $0.1 million, a decrease of $2.3 million from the first quarter of 2009 primarily due to revisions of incentive plans made in the prior year to create aligned incentives focused on launching a contract research organization and creating long-term value. Excluding the plan amendments, Adjusted EBITDA increased $0.5 million. During the first quarter of 2010, our research network was enrolling patients to 88 clinical trials as compared to 71 clinical trials in the first quarter of 2009, reflecting the commitment of our affiliated physicians to providing their patients access to alternative therapies. A delay in one large study resulted in a 3.9 percent decrease in the number of new patients enrolled in research studies compared to the same period in 2009.

3

Corporate Costs

Corporate costs, which represent general and administrative expenses excluding stock-based compensation, were $18.9 million in the first quarter of 2010 compared to $17.6 million in the first quarter of 2009. This increase is primarily related to higher marketing and branding costs associated with preparations to launch our “United” campaign as well as higher consulting fees for projects to complement our growth strategies.

Net Income (Loss) Attributable to the Company

Net loss attributable to the Company for the first quarter of 2010 was $0.1 million compared to net income of $1.0 million in the same period in 2009. The decrease is primarily due to incremental interest expense related to the refinancing of our senior notes and credit facility in the second quarter of 2009.

Impairment and Restructuring Charges

Impairment and restructuring charges are summarized in the table below (in millions):

	Q1 2010		Q1 2009
Severance costs	$	0.7	$	1.2
Other		0.1		0.2
	$	0.8	$	1.4

During the first quarter of 2010 and 2009, we recognized approximately $0.8 million and $1.4 million, respectively, in restructuring charges related primarily to employee separations.

Cash Flow and Working Capital Management

Cash from operations in the first quarter of 2010 was $14.0 million compared to $31.0 million generated from operations for the same period in 2009. The $17.0 million decrease reflects higher payments during the first quarter of 2010 for semiannual interest on our $775.0 million senior secured notes issued in June 2009.

As of May 5, 2010, the Company had liquidity of approximately $213.4 million, including cash and investments of approximately $123.8 million and availability under its revolving credit facility of $89.6 million.

Contingencies and Risks

A proposed Risk Evaluation and Mitigation Strategy (“REMS”) for Erythropoiesis-Stimulating Agents (“ESA”) was filed by ESA manufacturers with the U.S. Food and Drug Administration (“FDA”) in August, 2008 and became effective on March 24, 2010. The REMS is focused on ESA prescribing guidelines and includes additional patient consent/education requirements, medical guides and physician registration requirements. The REMS also outlines additional procedural steps that will be necessary for qualified physicians to order and prescribe ESAs for their patients.

We believe it is not currently possible to estimate the full impact of the REMS (on EBITDA) as prescribing patterns are changing now that the REMS is in effect. We believe a possible impact of the REMS could be further significant reductions in ESA utilization.

We continue to believe that we are well-positioned throughout Healthcare Reform. We also continue to believe that increased government spending required by the legislation, coupled with existing and growing federal budget deficits, will create future reimbursement pressures on providers as the government attempts to slow spending increases in healthcare and other entitlement programs.

Increased responsibilities of private payers will also increase pressure to reduce unit payments to providers from the private sector. These cost reduction pressures and incentives around Accountable Care Organizations (“ACOs”), will also increase competitive pressure on US Oncology from hospitals. While the reform legislation itself is neutral to positive for US Oncology, its failure to substantively address intensifying systemic cost and financing issues creates further pressure on us to implement our strategic plans aimed at these issues.

In late 2009, The Centers for Medicare and Medicaid Services (“CMS”) announced payment rates for services to be furnished under the 2010 physician fee schedule. Under the provisions, the current Sustainable Growth Rate (“SGR”) formula for setting aggregate Physician Fee Schedule spending would reduce payment for physician services by 21.3%. Historically, Congress has intervened and through the budgetary process provided funding to prevent significant cuts in reimbursement rates. The third and most recent delay to the payment reduction was passed by Congress and signed by President Obama on April 15, 2010. The Continuing Extension Act of 2010 (H.R. 4851) delays the payment reduction until May 31, 2010. We expect additional legislation from Congress will be enacted and currently estimate the impact to 2010 EBITDA of changes to CMS policies and payment rates will be approximately $1 million to $2 million reduction to oncology services paid under the CMS Physician Fee Schedule. If Congress fails to act and avert the scheduled 21.3% fee reduction, EBITDA could be reduced by approximately $7 million to $9 million. However, we continue to expect that the Congress, in the long run, will act to avert the SGR cut with a flat or marginally higher conversion factor.

As previously disclosed, during the first quarter of 2005, we received a subpoena from the United States Department of Justice’s Civil Litigation Division (“DOJ”) requesting a broad range of information about us

5

and our business, generally in relation to our contracts and relationships with pharmaceutical manufacturers. Also, as previously disclosed, the Company is currently involved in litigation with a formerly affiliated practice in Oklahoma. In addition, as previously disclosed, the Company and an affiliated practice have received a request for information from the Federal Trade Commission and a state Attorney General relating to an antitrust investigation of a recent transaction in which a group of physicians joined the affiliated practice. Also, as previously disclosed, on July 29, 2009 the Company received a subpoena from the U.S. Attorney’s Office, Eastern District of New York, seeking documents relating to its contracts and relationships with a pharmaceutical manufacturer and its business and activities relating to that manufacturer’s products. There were no material developments in these matters during the first quarter of 2010 or through the date of this release.

Results of US Oncology Holdings, Inc.

The results of US Oncology exclude those of its parent company, US Oncology Holdings, Inc. (“Holdings”). US Oncology conducts all substantive operations and, with the exception of nominal administrative expenses and items related to capitalization, the results of Holdings are substantially identical to those of US Oncology. Holdings reported Adjusted EBITDA of $55.1 million, net loss of $14.5 million and operating cash outflow of $4.7 million for the first quarter of 2010. The operating results of US Oncology and Holdings are reconciled below (in millions).

	Q1 2010			Q1 2009
Net Income (Loss) attributable to US Oncology	$	(0.1	)	$	1.0
Less: General and administrative expense		(0.1	)		—
Interest expense		(8.5	)		(10.4	)
Unrealized loss on swap		(5.1	)		(0.8	)
Effective tax rate differential		(0.7	)		4.7
Net Loss attributable to Holdings	$	(14.5	)	$	(5.5	)

Compared to the first quarter of 2009, interest expense associated with the Holdings’ notes decreased to $8.5 million from $10.4 million, despite increasing principal associated with settling interest in kind, due to lower LIBOR rates in the current period.

Changes in the fair value of the interest rate swap are reported currently in earnings. Although the interest rate swap is not accounted for as a cash flow hedge, the Company believes the swap, economically, remains a hedge against the variability of a portion of interest accruing on Holdings’ indebtedness.

6

As of March 31, 2010, the indebtedness issued by US Oncology Holdings, Inc., amounted to $509.7 million. In March 2010, the Company elected to settle interest due on September 15, 2010 through the issuance of additional notes expected to have a principal value of $17.1 million.

Discussion of Non-GAAP Information

In this release, the Company uses the term “EBITDA” and “Adjusted EBITDA”. EBITDA is earnings before interest, taxes, depreciation and amortization (including amortization of stock-based compensation), noncontrolling interest expense and other income (expense). EBITDA is not calculated in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Adjusted EBITDA is EBITDA before impairment and restructuring charges, loss on early extinguishment of debt and other non-cash charges. These measures are derived from relevant items in the Company’s GAAP financial statements. A reconciliation of Adjusted EBITDA to operating cash flow is included in this release.

The Company believes EBITDA is useful to investors in evaluating the value of companies in general, and in evaluating the liquidity of companies with debt service obligations and their ability to service their indebtedness. Management uses EBITDA as a key indicator to evaluate liquidity and financial condition, both with respect to the business as a whole and with respect to individual sites in the US Oncology network. Adjusted EBITDA is useful to investors as it eliminates certain amounts that are unusual in nature and not currently expected to be part of the Company’s ongoing operational performance. The Company’s senior secured credit facility also requires that it comply on a quarterly basis with certain financial covenants that include Adjusted EBITDA as a financial measure. Management also believes that EBITDA and Adjusted EBITDA are useful to investors, since they provide investors with additional information that is not directly available in a GAAP presentation.

As a non-GAAP measure, EBITDA and Adjusted EBITDA should not be viewed as alternatives to the Company’s GAAP financial statements, but should be read as a supplement to, and in conjunction with, the Company’s GAAP financial statements.
