In early 2014, recent Stanford University graduate Tyler Shultz was in a quandary. He had been working at Theranos, a blood-diagnostic company founded by Elizabeth Holmes, a Stanford-dropout wunderkind, for almost a year. Shultz had learned enough about the company to realize that its practices and the efficacy of its much-touted finger-prick blood-testing technology were questionable and that the company was going to great lengths to hide this fact from the public and from regulators.

Theranos and Holmes were Silicon Valley darlings, enjoying positive press and lavish attention from potential investors and technology titans alike. Just as companies like PayPal had revolutionized the stagnant payments industry and Uber had upended the for-hire transportation sector, Theranos had been positioned as the latest technology firm to substantially disrupt yet another mature sector: the medical laboratory business. By the start of 2014, the company had raised more than $400 million in funding, and had an estimated market valuation of $9 billion.

Shultz's situation was exacerbated by the fact that his grandfather, the highly respected former US Secretary of State George Shultz, was on the Theranos board and was one of Elizabeth Holmes's biggest supporters.

But Tyler Shultz worried about the customers he was convinced were receiving highly unreliable and often inaccurate blood-test results. With so much at stake, Shultz wondered how he should proceed. Should he raise his concerns with the firm's investors? Blow the whistle externally? Report to industry regulators? Go away quietly?

This case and its subsequent four brief follow-up cases are based largely on interviews with Tyler Shultz, and outline the dilemma he faced and the various steps he would take both to extricate himself from his unsavory position and let the public know the full extent of the deception at Theranos.

Five optional handouts are available to instructors to further discussion after the case has been debriefed. The handouts serve as additional decision points for the students if your class time permits.

Set in September 1992, this exercise provides teams of students the opportunity to negotiate terms of a merger between AT&T and McCaw Cellular. AT&T, one of the largest U.S. corporations, was the dominant competitor in long-distance telephone communications in the United States. McCaw was the largest competitor in the rapidly growing cellular-telephone communications industry. Prior to the negotiations, AT&T had no position in cellular communications. This case and its companion (F-1143) are designed to allow students to be assigned roles to play. The case may pursue some or all of the following teaching objectives: exercising valuation skills, practicing strategic analysis, exercising bargaining skills, and illustrating practical aspects of mergers and acquisitions.

Dick Mayo, one of the most celebrated value investors in America was puzzled by the New Economy's continuous bias toward growth investment strategies. He examines the basics of his philosophy versus that of a growth orientation by evaluating the long-term expected returns of several value and growth stocks. This case can be used to pursue several objectives: (1) to define value and growth investing-where the differences lie and whether one approach is superior to the other or whether both have merit; and (2) to discuss issues related to consistency of one's investment philosophy. Should one stay true to one's philosophy even when the market seems to run counter to it for a prolonged period of time? Can value investing deliver value in this New Economy or is it only an Old Economy concept? The students are instructed to perform basic valuations of Cisco Systems (a growth company), CVS, R.R. Donnelley, and Manor Care (value companies) and compute their long-term expected returns. The case comes with an Excel spreadsheet containing the data and relevant valuation ratios for the above firms. The valuations are straightforward, but they tell an interesting story: the expected returns of glamorous stocks in reality may not be so glamorous.

This case presents the dilemma of a multinational oil and gas company, ExxonMobil, as it factors in the ethical issues related to the environment and cultural differences in deciding whether to proceed with building a pipeline in Chad and Cameroon, two of the poorest and most corrupt developing countries in West Africa. The many players in this project included the World Bank--which cofinanced the project and put restrictions into place that would hopefully prevent pipeline-related government corruption in both Chad and Cameroon--and many environmental and human rights groups that warned of potential disaster. The case also covers the environmental and social analysis of the areas that would be affected by the pipeline.

Implementing a sustainability strategy requires firms to consider economic, strategic, environmental, and community perspectives. Suitable for MBA, undergraduate, and executive learners, this sustainability case covers innovation, intrapreneurship, and strategy. A technical note entitled, “Corporate Greenhouse Accounting: Carbon Footprint Analysis” (UVA-ENT-0113) is an effective complement. Frito-Lay’s Arizona facility pilots a program to take its snack chip manufacturing off the grid. Decision makers discuss operating, financial, marketing, and corporate strategy as the facility calculates its carbon footprint, converts to non-fossil-fuel energy sources, and stops relying on the scarce local water supply.

At what point in the tepid recovery from the global financial crisis should the Fed take a major step in normalizing U.S. monetary policy by greatly reducing its holdings of U.S. Treasury bonds? Federal Reserve Board Chairman Ben Bernanke faced this question in Spring 2012, even as he was concerned that the U.S. economy was on weaker footing than many believed. Suitable for both core and elective MBA courses in global financial markets and international finance, this case examines the risks associated with a policy some would consider monetizing the budget deficit. Students consider the factors behind the current and prospective levels of U.S. long-term interest rates from Bernanke's perspective.

Set in May 2000, these cases reflect the separate perspectives of the CEOs as they approach the negotiations of TSE International to acquire Yeats Valves. The task for the student is to complete a valuation analysis of the target and buyer, and to negotiate a price and exchange ratio with the counterparty. Each case contains a financial forecast only for that side; therefore, an important element in the negotiation is to obtain the private information of the other side, analyze it, and successfully negotiate terms of acquisition. The cases are relatively simple, and are offered as a first exercise in the valuation of the firm, and negotiation of an acquisition. They may be taught singly in usual case-discussion fashion, or combined into a joint-negotiation exercise where students are assigned parts to play. Used in a bilateral bargaining exercise, two teams of students are designated, each team representing one side of the negotiation and receiving a case designed for that team. The bargaining exercise provides a particular opportunity for joint teaching among instructors in finance, strategy, human behavior, and negotiation.

In the spring of 2004, Google was one of the most-talked-about IPO ideas since Netscape had gone public in 1995. Bullish investors believed Google could set off a string of successful IPOs following a lull in tech-offering activity since 2000. Executives at Google faced several questions in the following months: Should Google go public? What options did Google have for taking its shares to market? Was the traditional form of book-building necessarily the best course of action? Could a sealed-bid auction (e.g., W.R. Hambrecht's OpenIPO) yield superior results?

Recommended for MBAs, this case is one of a pair of cases used in a merger negotiation exercise. It is designed to be used with “Wm. Wrigley Jr. Company” (UVA-F-1607), but it can also be used on its own. Half of the class prepares only the Wrigley case and the other half uses the Mars case.

Wrigley and Mars are in the process of negotiating a merger agreement. Macroeconomic assumptions—particularly forecasting future sugar prices in an uncertain environment—and assumptions about Wrigley's value make Wrigley's future cash flows difficult to predict.
