According to the Wall Street Journal, medical tech start-up Theranos is low on cash. The paper reports:

A settlement between Theranos Inc. and Walgreens WBA 0.57% drugstore chain leaves the blood-testing lab firm with little money left in its coffers.

Theranos said Tuesday it settled a lawsuit by the Walgreen Co. unit of Walgreens Boots Alliance that claimed the blood-testing firm breached their contract and misled the drugstore chain about its capabilities.

Neither Theranos nor Walgreens would disclose terms of the settlement, though people familiar with the matter said the amount was more than $25 million. The Wall Street Journal reported in June that a tentative settlement had been reached, calling for Theranos to pay Walgreens less than $30 million.
