ZURICH, Oct 31 (Reuters) - Siemens could sell

off part of its stakes in Siemens Healthineers,

Siemens Energy and Fluence to help fund its

$10.6 billion Altair acquisition, Chief Financial Officer Ralf

Thomas said on Thursday.

Siemens currently holds 75% in medical equipment maker

Siemens Healthineers and 17% in Siemens Energy, as well as a 31%

stake in energy storage company Fluence.

"We have substantial financial potential from the sale of

shares in listed entities," Thomas told analysts.

"The specific intent to use the proceeds from selling shares

in listed companies is clearly related to this transaction," he

added, referring to the Altair acquisition.

Siemens also had around 3.5 billion euros ($3.81

billion)from selling its Innomotics electric motors and drives

business, a deal completed this month.

"We always said that we are not religious about a 75%

shareholding in Siemens Healthineers," Thomas said. "So, give or

take, 5% would be a meaningful assumption for a sell down."

Siemens planned to reduce its stake in Siemens Energy "in

the next couple of months," the executive said.

Still, Siemens would seek to minimise the impact of the

share sales on the stock prices of the companies affected.

When Siemens had previously reduced its Siemens Energy

investment, this was done without any "major noise or waves in

the market," Thomas said.

"We will definitely protect the share price of those

companies being affected," Thomas said.
