The company’s International segment, consisting primarily of Movianto which was acquired in the third quarter of 2012, contributed $123.0 million to second quarter consolidated revenues.

For the second quarter of 2013, net income was $28.9 million, or $0.46 per diluted share, a decline of 4.1% when compared to $30.1 million, or $0.48 per diluted share, for the same period of 2012. For the quarter, adjusted net income (non-GAAP), which excludes pre-tax charges of $0.6 million for acquisition-related and exit & realignment activities in each period, was $29.3 million, or $0.46 per diluted share, compared to $30.5 million, or $0.48 per diluted share, for the same period last year.

“While conditions remain challenging in the U.S. healthcare market, we continue to work on improving day-to-day operations, while making the right investments for our future,” said Craig R. Smith, chairman, president & chief executive officer of Owens & Minor. “We continue to receive validation of our approach to the market from our provider and manufacturer partners. While we are very encouraged by the progress we are making in Europe with Movianto, we recognize we still have work to do this year to achieve the goals we have established for our International segment.”

Consolidated operating earnings for the second quarter of 2013 were $50.1 million, a decrease of $3.1 million when compared to operating earnings of $53.2 million for the same period in the prior year.

Adjusted consolidated operating earnings (non-GAAP) for the second quarter of 2013 were $50.7 million, or 2.24% of revenues, decreased $3.1 million, when compared to adjusted operating earnings of $53.8 million, or 2.46% of revenues, in the same period of 2012. For purposes of comparison, the second quarter 2012 results did not contain results from the company’s International segment. On a sequential basis, second quarter adjusted consolidated operating earnings (non-GAAP) as a percentage of revenues improved when compared to both the first quarter of 2013 and the fourth quarter of 2012.

a decline of 7.6% when compared to net income of $59.5 million, or $0.94 per diluted share in the same period last year. For the year-to-date period, adjusted net income (non-GAAP), which excludes pre-tax charges of $2.6 million for acquisition-related and exit & realignment activities, was $56.9 million, or $0.90 per diluted share, compared to $59.8 million, or $0.94 per diluted share, in the first six months of 2012.

Consolidated operating earnings for the year-to-date period of 2013 were $97.9 million, or 2.16% of revenues, compared to operating earnings of $105.0 million, or 2.39% of revenues, for the same period of 2012. Adjusted consolidated operating earnings for the year-to-date period were $100.6 million, or 2.21% of revenues, compared to adjusted operating earnings of $105.7 million, or 2.40% of revenues for the same period last year.

Asset Management

The balance of cash and cash equivalents was $208 million at June 30, 2013. For the first half of 2013, the company reported cash provided by operating activities of approximately $180 million, compared to $143 million for the same period last year. The increase in cash from operations was primarily affected by an increase in accounts payable of $191 million, due to an increase in inventories and the timing of payments. Asset management metrics were positive with Domestic segment days sales outstanding (DSO) of 19.3 days as of June 30, 2013, compared favorably to days sales outstanding (DSO) of 19.5 as of June 30, 2012. Domestic inventory turns were 10.3 for the second quarter of 2013, compared to inventory turns of 10.8 for the second quarter of 2012.

Segment Results

Domestic segment revenues for the second quarter of 2013 were $2.14 billion, a decline of 1.9% when compared to the prior year’s second quarter revenue of $2.19 billion. The decline in second quarter Domestic segment revenues was primarily due to ongoing market trends, including lower rates of healthcare utilization and reduced government purchases, as well as the company’s continued rationalization of smaller, less profitable provider and supplier customers. For the year-to-date period, Domestic segment revenues were $4.3 billion, a decline of 2.4% when compared to revenues of $4.4 billion for the same period last year.

For the second quarter of 2013, Domestic segment operating earnings were $51.2 million, or 2.39% of segment revenues, a decline of approximately $2.5 million when compared to operating earnings of $53.8 million, or 2.46% of segment revenues, in the same period of 2012. During the second quarter of 2013, Domestic segment operating earnings benefitted from settlement of an administrative review by the state of California related to certain municipal sales tax incentives in the net amount of $3.5 million. Domestic segment operating earnings were also positively affected by certain supplier price changes. The majority of the benefits were offset by certain expenses, including higher than expected healthcare costs, litigation expenses, adjustments to benefit accruals, and expenses associated with the transition to a new fleet vendor. For the year-to-date period, Domestic segment operating earnings were $104.2 million, or 2.42% of segment revenues, a decline of $1.5 million when compared to segment operating earnings of $105.7 million in the same period in the prior year.

The International segment contributed revenue of $123.0 million for the second quarter of 2013 and had an operating loss of $0.6 million. The company attributed the sequential improvement in the International segment operating losses to improved capacity utilization and continued attention to cost control measures. For the year-to-date period, the International segment reported $244.0 million in revenues, and an operating loss of $3.6 million, which reduced year-to-date consolidated net income by $0.05 per diluted share.

2013 Outlook

The company reaffirmed its financial guidance for 2013, which remains unchanged since it was provided at the company’s Investor Day in November 2012.

For 2013, the company is targeting revenue growth of 2% to 4% and adjusted net income per diluted share of $1.90 to $2.00 for the year, which includes operating results from the Movianto acquisition, but excludes exit and realignment costs, as well as acquisition-related costs.

The 2013 outlook is based on certain assumptions that are subject to the risk factors discussed in the company’s filings with the Securities & Exchange Commission.

Use of Non-GAAP Measures

This earnings release contains financial measures that are not calculated in accordance with U.S. generally accepted accounting principles (“GAAP”). In general, the measures exclude items and charges that (i) management does not believe reflect Owens & Minor, Inc.’s (the “Company”) core business and relate more to strategic, multi-year corporate activities; or (ii) relate to activities or actions that may have occurred over multiple or in prior periods without predictable trends. Management uses these non-GAAP financial measures internally to evaluate the Company’s performance, evaluate the balance sheet, engage in financial and operational planning and determine incentive compensation.

Management provides these non-GAAP financial measures to investors as supplemental metrics to assist readers in assessing the effects of items and events on its financial and operating results and in comparing the Company’s performance to that of its competitors. However, the non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.

The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and the financial results calculated in accordance with GAAP and reconciliations to those financial statements set forth above should be carefully evaluated.
