August Adolphus Busch IV (born June 15, 1964) is an American businessman and former CEO of Anheuser-Busch.

[5] He is a great-great-grandson of Anheuser-Busch founder Adolphus Busch, and a great-great-great-grandson of Eberhard Anheuser who originally purchased the brewery in 1860.

He is the son of Susan (Hornibrook) and August Busch III, the former chairman, president and CEO of the company.

[7] In his early twenties, Busch earned a brewmaster's degree from Versuchs und Lehranstalt für Brauerei, a brewing institute in Berlin.

He worked as a brewing apprentice in the Old Malt House as a union member of Brewers & Maltsters Local 6 in St. Louis, Missouri, as an intern in the culture yeast center, and later as a foreman in packaging and shipping operations.

In an interview with Fortune magazine, he recounted a conversation with his father August Busch III, then the company's president and CEO, that Budweiser sales would grow only if the iconic brand's identity was reinvented.

"There was a culture weaved into the Budweiser brand... No one wanted to change it," Busch IV told the magazine.

The Budweiser and Bud Light commercials won the USA Today Super Bowl Ad Meter every year from 1999 to 2008.

[10] In 2002, Busch (and other family members) were passed over when the company named Patrick Stokes as its first non-family president and CEO.

Team owner William Dewitt Jr. said: "From the day we began planning for the new ballpark, we wanted to keep the name 'Busch Stadium'.

August Busch IV and Anheuser-Busch share our vision for continuing that tradition for our great fans and the entire St. Louis community.

[22] He also received a seat on InBev's board for a three-year term, $10.35 million in advance, and the promise of $120,000 a month in consultancy fees, as well as a personal security team.

[24] Busch holds advanced black belt degrees in the martial arts disciplines of Judo, Tae-Kwon-Do, and Hapkido.

He studied under Korean Grand Master Bong Yul Shin, who served as Busch's bodyguard.

[26] Busch married Kathryn "Kate" Thatcher, sixteen years his junior, in August 2006 in Bradford, Vermont[27] shortly before becoming CEO.

[5] Deputies found Busch at his Tucson townhouse 4 miles (6 km) away, with blood on his body, a sawed-off shotgun, and in a dazed condition exhibiting signs of amnesia.

[33] As part of regular procedure, police took blood and urine samples to assess whether and how much he had been drinking at the time of the accident.

[5] Busch was arrested at the age of 20 in St. Louis after leading undercover police in an unmarked car on a chase with speeds reaching between 85 and 90 mph on Kingshighway Boulevard in the Central West End of the city.

[39][40] A toxicology report in February 2011 indicated Martin had cocaine and oxycodone in her system; pill bottles with her name were found containing each of these.

The St. Louis County Prosecutor confirmed that Martin had lethal levels of both oxycodone and cocaine in her system, and ruled she died of an accidental overdose.

[42] Adrienne's mother announced she was hiring New York attorney John Q. Kelly (who previously represented Beth Holloway and the estate of Nicole Brown Simpson) to pursue the case, and also said she would seek custody of her grandson.

[43][44] On April 20, 2011, the press reported that Busch had agreed to a $1.5 million settlement with Kevin Martin on behalf of his son.

[45] On July 10, 2017 Busch was arrested in Swansea, Illinois after he allegedly tried to fly while intoxicated a helicopter containing 4 guns and 8 dogs.
