Exhibit 99.5

Announcement Posted on Philips’ Internal Website on December 17, 2014

Headline: Major acquisition to boost Philips’ Image Guided Therapy business

Philips today announced that it has entered into an agreement to acquire Volcano, a global healthcare company that is listed in the US. The company is a leader in catheter–based imaging and measurements for minimally invasive diagnostics and treatment of cardiovascular disease.

Based in San Diego, Volcano produces and sells advanced catheters that are capable of imaging the interior of blood vessels and perform measurements. These technologies are increasingly being used in conjunction with Philips’ offering of live-image guidance solutions, to improve procedural outcomes

“Image-guided therapies provide significant benefits for healthcare systems and patients, including reduced patient trauma, shorter recovery times and hospital stays, and lower costs. As a result, our clinical partners and customers are asking for a tighter integration of imaging and measurement technologies to enable such therapies,” said CEO Frans van Houten. “This transaction allows us to provide our customers with an integrated solution to improve procedural outcomes at a decisive stage in the health continuum

“The interventional cardiologist has to monitor the relevant pieces of information from various imaging and measurement technologies and then combine that in his head to guide his movements,” said Carlos E. Ruiz, Professor of Cardiology in Pediatrics and Medicine, North Shore Health System and Lenox Hill Hospital. “There is therefore, a tremendous opportunity for Philips for tighter integration of the imaging and measurement technologies and to present the relevant data in one intuitive and interactive view, as that will make a world of difference for the interventional cardiologist.”

Upon closing of the transaction, which is anticipated in the first quarter of 2015, Volcano and its 1,800 employees will become part of Philips’ Image Guided Therapy (IGT) business, which is led by Bert van Meurs.

Volcano had sales of $400 million in 2013, half of which was generated in the US and half in the rest of the world (of which Japan is the largest market).
