Feb 19 (Reuters) - Warren Buffett's Berkshire Hathaway ( BRK/A )

said it has sold an additional 750,000 shares of DaVita ( DVA )

, reducing its stake in the kidney dialysis services

provider by about 2% to 35.14 million shares worth $5.4 billion.

The sales between February 14 and 19 totaled about $115

million, according to a Wednesday night filing with the U.S.

Securities and Exchange Commission.

The sales reduced Berkshire's ownership stake in DaVita ( DVA ) to

about 44%, based on DaVita's ( DVA ) 80 million outstanding shares as of

January 31.

The latest sales follow a sale by Berkshire of 203,091

DaVita ( DVA ) shares back to the Denver-based company on February 11,

pursuant to an agreement for DaVita ( DVA ) on a quarterly basis to

repurchase enough shares to reduce Berkshire's stake to 45%.

It wasn't immediately clear why Berkshire sold

additional DaVita ( DVA ) shares.

The latest selling came after DaVita's ( DVA ) 2025 earnings

outlook on February 13 disappointed investors.

DaVita's ( DVA ) share price fell 11% the following day. The

shares closed at $154.96 on Wednesday.

Neither Berkshire nor DaVita ( DVA ) immediately responded to

requests for comment on Wednesday after market hours.

Berkshire has owned DaVita ( DVA ) shares since the fourth

quarter of 2011.

The investment was spearheaded by Ted Weschler, who

joined Berkshire as a portfolio manager in 2012 and had invested

in DaVita ( DVA ) at his former hedge fund firm Peninsula Capital

Advisors.

Buffet has led Omaha, Nebraska-based Berkshire since

1965.
