RESMED APPOINTS MICHAEL FARRELL AS CHIEF EXECUTIVE OFFICER;

ROBERT DOUGLAS APPOINTED PRESIDENT AND CHIEF OPERATING OFFICER

San Diego, California, Feb. 20, 2013 - ResMed Inc. (NYSE: RMD) announced today that effective March 1, 2013, Michael (“Mick”) Farrell will succeed Dr. Peter C. Farrell as ResMed’s chief executive officer (CEO) and be appointed to its board of directors. Robert (“Rob”) Douglas will become ResMed’s president and chief operating officer (COO). Current CEO, chairman of the board and founder, Dr. Farrell, will become executive chairman. Together, Mr. Farrell and Mr. Douglas will comprise the office of the CEO and Dr. Farrell will work together with them on an as-needed basis through the end of calendar year 2013, when he will transition to non-executive chairman. In addition, Dr. Jim Hollingshead has been named president, Americas.

“A thorough review of potential candidates to succeed Peter was conducted by the board’s CEO succession committee, working closely with the nominating and governance committee and a top-tier executive search consultancy,” commented Dr. Gary Pace, lead director of ResMed’s board and chairman of the board’s succession committee. “It was easily determined that members of the very talented and experienced team that have driven much of the company’s great success over the past decade would be best suited to lead the company to its next stages of growth and development. Mick led the team in the Americas that grew sales over 30 percent during the seven quarters that he was president of that region. He also established a vision for the organization that extended beyond driving revenue and market share to include a focus on the number of lives enhanced by ResMed products. Mick’s strengths and accomplishments leading sales, marketing, business development and commercial strategy teams equip him well to become ResMed’s next CEO. Rob’s expertise and excellent track record of increasing productivity and efficiencies of global operations, as well as success in growing sales, make him the ideal choice for COO and president. In addition, he was instrumental in creating our successful manufacturing presence in both Australia and Singapore. At this time, we also want to thank Peter for resuming the role of CEO over the past couple of years and now turning over the helm to Mick and Rob while staying on as executive chairman of the board.”

“I have little doubt that Mick and Rob will build on ResMed’s momentum as a global driving force in sleep and respiratory medicine, and as a leader in the medical device industry,” said Dr. Peter Farrell. “Mick has been with us for more than 12 years; Rob for more than 11. This is a deeply experienced and accomplished duo to lead ResMed. They have also played an integral role in developing and preserving the unique culture established within ResMed which has proved to be an extremely important component of the success of the company. The board and I are extremely confident in the ability of our senior management, as well as the talent at all levels throughout ResMed.”

“Rob and I have worked in collaboration with the entire organization at ResMed for more than a decade to help drive the success of our core business by producing the best products on the market, becoming the preferred mask brand by patients and promoting the awareness of sleep-disordered breathing,” commented Mick Farrell. “I am extremely excited to be taking the reins of a company that will contribute to the well-being and improved quality of life of millions of patients suffering from sleep-disordered breathing. Looking forward, we have huge opportunities to leverage current ResMed offerings and our product pipeline to change the lives of millions of patients who suffer from such co-morbidities as congestive heart failure and chronic obstructive pulmonary disease. Our future success will be accelerated by ResMed’s intense focus on innovation, breaking down barriers to diagnosis and treatment, and an emphasis on our culture, which attracts world-class talent who learn to share our passion for changing lives, one breath at a time.”

“I am looking forward to working together with Mick and the rest of the team to build on the success and achievements of ResMed,” said Rob Douglas. “We are uniquely positioned in healthcare. We improve patients’ quality of life, slow down and even improve other medical co-morbidities, and reduce the cost of healthcare. I am confident we will continue to succeed in the future.”
