Another speculated on the strategic implications of the purchase, saying that the company might be taken private.

Aurinia has been under the spotlight recently due to significant restructuring efforts.

This came alongside changes to its board of directors, including Tang’s appointment, following CEO Peter Greenleaf’s conditional resignation as director.

In its third-quarter (Q3) earnings report, Aurinia posted earnings of $0.10 per share, significantly beating analysts’ estimates of $0.01. Revenue for the quarter reached $67.77 million, exceeding the expected $57.48 million.

Year-to-date, Aurinia’s stock has climbed over 4%, with momentum now building on insider confidence and operational changes.
