RESMED INC ANNOUNCES RECORD FINANCIAL RESULTS FOR

QUARTER AND SIX MONTHS ENDED DECEMBER 31, 2006

SAN DIEGO, California, February 6, 2006 - ResMed Inc (NYSE: RMD) today announced record revenue and income results for the quarter ended December 31, 2006. Revenue for the quarter was $178.4 million, a 22% increase over the quarter ended December 31, 2005. For the current quarter, pro forma income from operations and pro forma net income were $47.0 million and $33.7 million, an increase of 23% and 25%, respectively (pro forma measures exclude the impact of stock-based compensation costs, restructuring expenses and amortization of acquired intangible assets, which are described below). Pro forma diluted earnings per share for the quarter ended December 31, 2006, were $0.43, an increase of 20%, compared to the December 31, 2005, quarter. GAAP operating income was $40.7 million for the current quarter, while net income was $29.0 million or $0.37 per diluted share. Gross margin was 62.6% for the quarter ended December 31, 2006.

Pro forma selling, general and administration (SG&A) costs for the quarter were $53.5 million, an increase of $8.2 million, or 18%, over the same period in fiscal 2006. Pro forma SG&A costs were 30% of revenue in the December quarter, compared to 31% in the same period in fiscal 2006. GAAP SG&A costs were $57.3 million for the quarter, an increase of $8.4 million or 17% over the quarter ended December 31, 2005. The increase in SG&A was primarily due to the addition of selling and administration personnel and related expenses necessary to support our sales growth.

Pro forma research and development expenditure during the quarter was $11.5 million, or approximately 6% of revenues. GAAP R&D expense during the quarter was $12.0 million or approximately 7% of revenue. GAAP R&D expenses increased 40% year over year and are expected to remain between 6% and 7% of net revenue through fiscal year 2007.

For the six months ended December 31, 2006, revenues were $342.0 million, an increase of 25% over the $273.5 million for the six months ended December 31, 2005. For the six months ended December 31, 2006, pro forma income from operations and pro forma net income were $87.6 million and $62.5 million, an increase of 28% and 31%, respectively. GAAP net income for the six months ended December 31, 2006, was $54.0 million or $0.69 per diluted share.

Amortization of acquired intangibles of $1.7 million ($1.1 million net of tax) incurred during the quarter ended December 31, 2006, consisted of amortization of acquired intangible assets associated with our acquisitions of Resprecare, Hoefner, Saime, PolarMed and Pulmomed. Stock-based compensation costs incurred during the quarter ended December 31, 2006, of $4.6 million ($3.6 million net of tax) consisted of expenses associated with stock options granted to employees and the employee stock purchase plan.

The Company is providing tabular reconciliation of GAAP operating income and GAAP net income with pro forma operating income and pro forma net income, excluding the impact of stock-based compensation costs, restructuring expenses and amortization of acquired intangible assets, for the three-month and six-month periods ended December 31, 2006, and December 31, 2005.

Inventory, at $141.9 million, increased by $25.7 million compared to June 2006 levels primarily to accommodate sales growth and the introduction of new products including the Adapt SV and Tango. Accounts receivable days sales outstanding, at 72 days, were marginally higher than the December 2005 levels of 70 days.

Peter C. Farrell, PhD, Chairman and Chief Executive Officer, commented, “In the second quarter of fiscal 2007, overall Americas sales for our sleep products increased by 23%; including sales from our motor division, Americas sales increased by 20% over the year ago quarter. In this regard it is noted that the ResMed motor division has significantly reduced sales of low margin non-core products to concentrate more exclusively on the supply of motors for ResMed products. Sales growth in sleep products for the Americas reflects continuing strong demand for our Swift nasal pillows system, our full-face masks and the Adapt SV, which was only launched in the previous quarter. Sales outside of the Americas totaled $84.4 million, a 24% increase over last year. Operating cash flow for the September quarter was $18 million.”

Dr. Farrell continued, “We are pleased with the in-roads we continue to make into the cardiology and complex sleep apnea markets with the Adapt SV and we are making good progress with our Occupational Health strategy. We are also excited by the upcoming launch of the Tango into the value end of the CPAP market.”

Reconciliation of Non-GAAP Financial Measures (Unaudited)

(Dollars in thousands except per share amounts)

In managing its business, ResMed makes use of certain non-GAAP financial measures in evaluating the Company’s results of operations. The measure, “pro forma operating income” is reconciled with GAAP operating income in the table below:

The measure, “pro forma net income” is reconciled with GAAP net income in the table below:

ResMed believes that presenting diluted earnings per share, excluding the impact of stock-based compensation costs, restructuring expenses and amortization of acquired intangible assets is an additional measure of performance that investors can use to compare operating results between reporting periods. In addition, the events giving rise to the restructuring expenses are not associated with the Company’s normal operating business and are expected to result in future market opportunities, cost savings, and other benefits.

Management of the Company uses non-GAAP information internally in planning, forecasting, and evaluating the Company’s results of operations in the current period and in comparing it to past periods. The Company also uses these non-GAAP measures in evaluating management performance for compensation purposes. Management believes that this information also provides investors better insight in evaluating the Company’s earnings performance from core operations and provides consistency in financial reporting.

Management believes disclosure of non-GAAP earnings has economic substance because the excluded expenses represent non-cash expenditures, or relate to transactions that are variable in nature between reporting periods. Our use of non-GAAP earnings is intended to supplement, and not to replace, our presentation of net income and other GAAP measures. Like all non-GAAP measures, non-GAAP earnings are subject to inherent limitations because they do not include all the expenses that must be included under GAAP. We compensate for the inherent limitations of non-GAAP measures by not relying exclusively on non-GAAP measures, but rather by using such information to supplement GAAP financial measures.
