John Bryan Tolbert
Hall Group representative involved in the firm's Theranos investments.
About
John Bryan Tolbert testified for the prosecution about Hall's review of Theranos and investments made in 2006 and 2013. He described the materials and projections considered during the earlier review, including anticipated contracts, revenue growth, positive cash flow, an expected public offering, and a fingerstick testing system using cartridges and a reader.
Tolbert testified that Hall received little information directly from Theranos for several years and generally obtained updates through Chris Lucas. In December 2013, Tolbert participated in and recorded an investor call with Holmes because Hall might miss it and wanted a record of pertinent investment information. Tolbert identified Holmes's voice and authenticated the recording.
Tolbert said he understood the call to describe significant existing fingerstick-testing capabilities, reduced blood volume and variability, accelerated retail expansion, an established pharmaceutical business, and military-related work. He testified that the call was central to Hall's decision to invest another $5 million.
Tolbert also identified the purchase documents and explained the funding of the investment. He testified that he authorized the transfer, with $4.875 million going to Theranos and $125,000 representing a commission.
Cross-examination tested how much information Tolbert had before the 2013 investment. He said he had no direct contact with Theranos for roughly six years, had asked for but not received financial statements, and asked no questions during the recorded investor call. He could not identify the precise investment decision date, did not directly seek more information or retailer contracts, and agreed that the opportunity was difficult to analyze. Tolbert said the group still had questions but believed it had enough information to proceed, and that Hall had authorized him to choose the investment amount or decline to invest.
