Natus Medical Announces 2011 Third Quarter Financial Results

- Company Updates 2011 Revenue and Non-GAAP Earnings per Share Guidance

SAN CARLOS, Calif.--(BUSINESS WIRE)--October 27, 2011--Natus Medical Incorporated (NASDAQ:BABY) today announced financial results for the three and nine months ended September 30, 2011.

The Company reported revenue of $51.3 million for the third quarter ended September 30, 2011, compared to revenue of $53.2 million reported in the comparable quarter of the previous year. Embla Systems, which the company acquired on September 15, 2011, contributed $1.3 million of revenue. Net income was $153,000 or $0.01 per diluted share, compared to net income of $3.6 million or $0.12 per diluted share for the third quarter of 2010.

For the nine months ended September 30, 2011, the Company reported net income of $5.6 million, or $0.19 per diluted share, compared to net income of $6.7 million, or $0.23 per diluted share, for the comparable period in 2010.

The Company reported non-GAAP earnings per share of $0.07 per diluted share for the third quarter of 2011 compared to $0.16 per diluted share for the same period in 2010. Non-GAAP net income was $2.1 million in the 2011 period compared to $4.8 million in the third quarter of 2010. For the nine months ended September 30, 2011 non-GAAP net income was $9.9 million, or $0.34 per share, compared to $12.0 million or $0.41 per share for the same period in 2010.

In commenting on the third quarter revenue results, Jim Hawkins, Chief Executive Officer of the Company said, “The third quarter revenue shortfall, which is consistent with the expected results we announced on October 10th, was primarily attributable to our neurology business where we experienced order delays in both domestic and international markets and also a reduction in order size in the United States. Our Medix subsidiary, with newborn care products sold primarily in Latin America, also experienced a shortfall that was due to delayed orders. Our other newborn care products, including our newborn hearing screening, newborn brain monitoring, and phototherapy product lines performed to expectations in the third quarter.”

“In the third quarter we experienced a reduction in large capital equipment orders over $300,000, primarily in our domestic neurology business. Although some orders we expected were placed during the quarter at significantly reduced order size, other orders were not placed at all. We believe that the orders we were working on during the third quarter have not been lost, but have been merely delayed, and we expect that they will eventually be placed with Natus,” added Hawkins. “We experienced similar sales activity in late 2008 and early 2009 and then saw those delayed orders placed in following quarters.”

“We look forward to capitalizing on the opportunity that recently acquired Embla Systems brings to our neurology business as we are now a leader in the growing worldwide market for diagnostic sleep products,” added Hawkins. “We expect the Embla acquisition to be accretive to our earnings in 2012, adding approximately $0.08 to non-GAAP earnings per share.”

As of September 30, 2011, the Company had cash, cash equivalents, and short-term investments of $30.8 million, stockholders' equity of approximately $275 million, and working capital of approximately $89 million.

Financial Guidance

Natus updated its 2011 financial guidance. For the full year 2011, the Company expects to report revenue of approximately $234 million and non-GAAP earnings per share of approximately $0.48.

For the fourth quarter 2011, the Company expects to report revenue of approximately $65 million and non-GAAP earnings per share of approximately $0.15. This compares to revenue of $63.2 million and non-GAAP earnings per share of $0.24 reported in the fourth quarter of 2010.

The Company's fourth quarter and full year 2011 non-GAAP earnings per share guidance excludes amortization expense associated with acquisition-related intangible assets, which the Company expects to be approximately $5.2 million and $1.3 million for the full year and fourth quarter 2011, respectively, and which the Company expects will reduce GAAP earnings per share by approximately $0.11 and $0.03 for the full year and quarter, respectively. The non-GAAP earnings per share guidance for those periods also excludes the effects of restructuring charges that the Company expects it may incur in the fourth quarter of 2011, the amount and timing of which have not yet been determined, as well as the impact any future acquisitions might have on its results of operations.

The Company's non-GAAP guidance includes the impact of expensing employee share based compensation. All non-GAAP earnings per share amounts are on a diluted basis.

Use of Non-GAAP Financial Measures

The Company's non-GAAP results for the three and nine months ended September 30, 2011 exclude amortization expense associated with certain acquisition-related intangible assets, restructuring charges associated primarily with employee severance costs, and directs costs of the Embla acquisition, and its fourth quarter and full year guidance exclude such amortization expenses, restructuring charges, and acquisition costs, and the impact of any future acquisitions.

The Company believes that the presentation of historical results and guidance excluding these items provides meaningful supplemental information to both management and investors that is indicative of the Company's core operating results. Therefore, the Company believes these non-GAAP financial measures facilitate comparison of operating results across reporting periods. A reconciliation between the Company's historical results of operations on a GAAP and non-GAAP basis for the periods reported is included as part of the condensed consolidated statements of operations at the end of this release.

The Company believes that both management and investors benefit from referring to these non-GAAP financial measures in assessing the Company's performance and when planning, forecasting, and analyzing future periods. These non-GAAP financial measures also facilitate management's internal comparisons to the Company's historical performance. 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 should be carefully evaluated.
