THERANOS REACHES SETTLEMENT WITH PARTNER FUND MANAGEMENT

Tender offer recapitalizing major shareholders scheduled to close May 15

PALO ALTO, Calif. [May 1, 2017] – Theranos, Inc. announced today that it has resolved two lawsuits brought against it by Partner Fund Management LP (PFM), a San Francisco-based hedge fund. PFM invested $96.1 million in Theranos in February 2014.

The parties’ settlement, the terms of which are confidential, will result in the dismissal of all claims by PFM against Theranos and its officers and directors. The Company now brings to a close the burden and expense of litigation and preserves resources to bring the miniLab platform to market.

“Theranos is pleased to have resolved both lawsuits with PFM. Although we are confident that we would have prevailed at trial, resolution of these two cases allows our tender offer to go forward and enables us to return our focus where it belongs, which is on executing our business plans and delivering value for our shareholders,” said Theranos General Counsel David Taylor.

Theranos remains in the midst of a tender offer involving its most significant shareholders. Through the offer, the Company’s C-1 and C-2 investors will receive additional shares, contributed by Elizabeth Holmes, such that non-participating shareholders will not be diluted by the transaction. As of May 3, holders of approximately 99% of the shares subject to the tender have committed to participate, in advance of the expected May 15, 2017 close.

On April 17, 2017, Theranos announced the resolution of all outstanding legal and regulatory proceedings between the Company and Centers for Medicare & Medicaid Services (CMS). On April 18, 2017, Theranos announced the resolution of all existing or potential claims by the Arizona Attorney General related to Theranos blood testing services in Arizona.
