He received a bachelor's degree in accounting from the University of Arkansas in 1989
and an MBA from the University of Tulsa in 1991. In 1984, McMillon began his career with
Walmart as a summer associate in a distribution center. In 1990, while pursuing his MBA, he
rejoined the company in a Tulsa, Oklahoma Walmart store. Much of McMillon’s 22-year career
has been in merchandising in the Walmart U.S. division, with experience in food, apparel and
general merchandise. He has also held various merchandising positions at Sam's Club and
Walmart International in addition to holding leadership roles in all three operating segments of
the company.
From 2006 to 2009, McMillon served as President and CEO of Sam’s Club, an operating
segment of Walmart, with sales of more than $46 billion annually during his tenure. Prior to
heading Sam’s Club, McMillon held the role of Executive Vice President of merchandising and
replenishment and helped drive the renewed focus on small business owners. From February

Elon Musk (CEO Tesla)
Elon Reeve Musk is a South African-born Canadian-American business magnate, engineer,
inventor and investor. He is the CEO and CTO of SpaceX, CEO and product architect of Tesla
Motors, and chairman of SolarCity. He is the founder of SpaceX and a co-founder of Zip2,
PayPal, and Tesla Motors. He has also envisioned a conceptual high-speed transportation
system known as the Hyperloop and has proposed a VTOL supersonic jet aircraft with electric
fan propulsion. At age 10, he discovered computing with the Commodore VIC-20. He taught

2. himself computer programming and at age 12 sold the code for a BASIC-based video game he
created called Blastar to a magazine called PC and Office Technology for approximately US$500.
A web version of the game is available online.
Musk was severely bullied throughout his childhood, and was once hospitalized when a
group of boys threw him down a flight of stairs, and then beat him until he blacked out. Musk
was initially educated in private education, attending the English-speaking Waterkloof House
Preparatory School. Musk later graduated from Pretoria Boys High School and moved to Canada
in June 1989, just before his 18th birthday, after obtaining Canadian citizenship through his
Canadian-born mother.
Musk led the Series A round of investment in February 2004, joining Tesla's board of
directors as its chairman. Musk took an active role within the company and oversaw Roadster
product design at a detailed level, but was not deeply involved in day-to-day business
operations. Following the financial crisis in 2008, Musk assumed leadership of the company as
CEO and product architect, positions he still holds today. Tesla Motors first built an electric
sports car, the Tesla Roadster, with sales of about 2,500 vehicles to 31 countries. Tesla began
delivery of its four-door Model S sedan on June 22, 2012. It unveiled its third product, the
Model X, aimed at the SUV/minivan market, on February 9, 2012; the Model X launch was
however delayed until September 2015. In addition to its own cars, Tesla sells electric
powertrain systems to Daimler for the Smart EV, Mercedes B-Class Electric Drive and Mercedes
A Class and to Toyota for the RAV4 EV. Musk was able to bring in both companies as long-term
investors in Tesla. To overcome the range limitations of electric cars, Musk said in an interview
with All Things Digital in May 2013 that Tesla is "dramatically accelerating" their network of
supercharger stations, tripling the number on the East and West coasts of the U.S. that June,
with plans for more expansion across North America, including Canada, throughout the year.
He is reported to have a 32% stake in Tesla, which was valued at US$18 billion in
November 2013. While previously taking large annual salaries at Tesla Motors, for example
US$78.2 million in 2012; when Musk became the highest paid CEO in the world, as of 2014,
Musk's annual salary is one dollar, and similar to Steve Jobs and others, the remainder of his
compensation is in the form of stock and performance-based bonuses. In 2014, Musk
announced that Tesla Motors will allow its technology patents to be used by anyone in good
faith in a bid to entice automobile manufacturers to speed up development of electric cars.
"The unfortunate reality is electric car programs (or programs for any vehicle that doesn't burn
hydrocarbons) at the major manufacturers are small to non-existent, constituting an average of
far less than 1% of their total vehicle sales", Musk said.
