Exhibit 99.1 Natus Medical Reports Record Third Quarter Revenue and Earnings; Company Provides 2006 Earnings Guidance SAN CARLOS, Calif.--(BUSINESS WIRE)--Oct. 26, 2005--Natus Medical Incorporated (Nasdaq:BABY) today announced financial results for the three and nine months ended September 30, 2005. The Company reported record third-quarter revenue of $10.6 million for the three months ended September 30, 2005, an increase of $1.6 million or 17% from $9.0 million reported in the comparable period of the previous year. The Company reported record third-quarter net income of $1.5 million or $0.08 per diluted share for the 2005 period, compared with net income of $147,000 or $0.01 per share for the comparable period in 2004. For the first nine months of 2005, revenue increased 17% to $30.4 million, from $26.0 million reported in the comparable period in 2004. Net income for the nine months ended September 30, 2005 was $3.7 million or $0.20 per diluted share, compared to a loss of $3.9 million, or ($0.23) loss per share reported in 2004. Gross margin improved to 65.4% for the three months ended September 30, 2005, compared with 57.1% for the third quarter of 2004. The gross margin for the 2005 period was favorably impacted by reductions in materials costs and by a higher margin contributed by the Company's Fischer-Zoth subsidiary that was acquired on September 28, 2004. For the three months ended September 30, 2005 operating expenses increased approximately 19% to $5.6 million, compared with $4.7 million for the third quarter of 2004. Costs associated with the operations of the Company's Fischer-Zoth subsidiary and ongoing costs of complying with the Sarbanes-Oxley Act contributed to an approximate $1.4 million increase in operating costs. The increase was partially offset by $550,000 for acquired in-process research and development recorded in the third quarter of 2004 that did not recur in 2005. Taken together, these factors led to an approximate $880,000 increase in operating expenses in the 2005 period. As of September 30, 2005, the Company reported cash, cash equivalents and short-term investments of $41.8 million, representing an increase of approximately $6.1 million from the corresponding amount at December 31, 2004. Additionally, the Company reported stockholders' equity of $56.8 million and working capital of $45.6 million as of September 30, 2005. "We are extremely pleased with our results for the third quarter," said Jim Hawkins, President and Chief Executive Officer of Natus Medical. "The acquisition of Fischer-Zoth contributed to our improved gross profit on a quarter-over-quarter basis, and much of the increase in our operating expenses was related to their operations. We are also pleased that our operating margin was consistent with our plan." "2005 continues to be a great year for Natus as we have shown consistent growth, improving gross profits, and increased profitability. Even with these excellent results, we can't help but look ahead to 2006 anticipating the acquisition of Bio-logic Systems. We believe this acquisition will allow Natus to expand into new markets and strengthen our presence in existing markets, while achieving synergies that should result in increased earnings," Hawkins added. Financial Guidance The Company updated financial guidance for 2005. The Company expects to report earnings per diluted share of $0.31 to $0.32 on revenue of $42.2 to $42.5 million in 2005. This compares to a loss per share of $0.17 on revenue of $36.5 million reported last year. Natus had previously said it expected to earn $0.30 to $0.33 per diluted share in 2005 on revenue of $41.6 to $43.0 million. For 2006, the Company expects to report diluted earnings per share of $0.48 to $0.50 on revenue of $78 to $80 million. These expected results assume the Company completes its acquisition of Bio-logic Systems in early January 2006. Additionally, the Company expects that its effective tax rate will rise to 15% in 2006. The estimates of earnings per share do not include any one-time charges associated with the acquisition of Bio-logic Systems or the impact of expensing employee stock options. The Company is continuing to evaluate the impact of expensing employee stock options, which it will be required to do under Financial Accounting Standards Board Statement No. 123R, "Share-Based Payment" beginning with its first quarterly period in 2006.
