Natus Medical Announces Record Second Quarter 2013 Financial Results

SAN CARLOS, Calif. (August 1, 2013) – Natus Medical Incorporated (Nasdaq:BABY) today announced financial results for the three months ended June 30, 2013.

For the second quarter ended June 30, 2013, the Company reported revenue of $82.3 million, up 35% from $61.0 million in the second quarter of the previous year. Net income was $4.0 million, or $0.13 per diluted share, compared with net income of $0.3 million, or $0.01 per diluted share in the second quarter of 2012.

The Company reported non-GAAP earnings per share of $0.21 per diluted share for the second quarter 2013, up 91% from the $0.11 per diluted share reported for the second quarter of 2012.

“I am very pleased with both our record second quarter non-GAAP earnings and gross profit margin that increased to 60% from 57% last year,” said Jim Hawkins, President and Chief Executive Officer of the Company. “As we previously announced, weakness in international markets, particularly Europe and to a lesser extent Latin America, led to a second quarter revenue shortfall from the guidance we issued earlier in the quarter. This shortfall was in both our newborn and neurodiagnostic product categories. Domestic revenue was within our expectations.”

“I am also pleased to report that Saudi Arabia has adopted newborn hearing screening as a standard of care and has purchased our ALGO hearing screeners. With over a half million births every year, we expect this market to result in a significant ongoing supply business,” continued Hawkins.

“Our improved operating margin has been driven by increased operating leverage as a result of our acquisition strategy and reflects the leadership position of our products in both newborn care and neurology,” added Hawkins. “We are committed to achieving our 2013 non-GAAP operating margin goal of 12% and our longer term goal of non-GAAP operating margins of 13% to 17%, consistent with our historical levels. Our second quarter results demonstrate our progress towards this goal.”

The Company’s cash and cash equivalents increased $4.6 million to $28.9 million during the quarter and net debt was reduced by $2.2 million.

Financial Guidance

The Company provided guidance for the third and fourth quarter 2013 and updated its guidance for the full year 2013.

For the third quarter 2013, the Company expects to report revenue of $80 million to $82 million and non-GAAP earnings per share of $0.18 to $0.21.

For the fourth quarter 2013, the Company expects to report revenue of $84 million to $88 million and non-GAAP earnings per share of $0.22 to $0.25.

For the full year 2013 the Company expects to report revenue of $332 million to $338 million and non-GAAP earnings per share of $0.76 to $0.82.

The Company expects to record a restructuring charge of approximately $2 million during the third quarter associated with a plan to restructure and streamline operations and reduce costs. Non-GAAP earnings per share estimates do not include these estimated restructuring charges.

Included in the Company’s 2012 third and fourth quarter revenues were one time shipments of proprietary product to CareFusion. Natus agreed to manufacture this product for CareFusion through a supply agreement that was part of the purchase of Nicolet. These one-time revenues totaled $3.4 million; $1.2 million in the third quarter and $2.2 million in the fourth quarter of 2012.

The Company’s full year 2013 and quarterly non-GAAP earnings per share guidance exclude amortization of acquisition related intangibles, acquisition related charges, restructuring charges, and their related tax effects.

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

Use of Non-GAAP Financial Measures

The Company’s non-GAAP results for the second quarter 2013 exclude amortization expense associated with certain acquisition-related intangibles, restructuring charges, and direct costs of acquisitions.

The Company believes that the presentation of results excluding these charges 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 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.
