Wayne Enterprises is an economical advanced technology and military defense developments company based in Gotham City and owned by the famous Wayne Family, which specializes in various industrial aspects.
Wayne Enterprises was the most famous corporation in Gotham City. When the city fell in an economic downturn caused by the League of Shadows, Thomas Wayne nearly bankrupted the company by building a cheap public monorail system. Thomas and his wife Martha were later mugged and murdered taking their son Bruce to the opera, inspiring Gotham into rebuilding itself. During Bruce’s travels around the world, Wayne CEO William Earle took the company public and shieing away from "what Thomas Wayne would have done" to focus on heavy weapons manufacturing
By the time Bruce finally returned to Gotham, he didn't show obvious interest in reclaiming the family business. Instead, he chose to work in the Applied Sciences division, using it and company chief activist Lucius Fox to provide him with high-tech equipment. He took gear originally made for the U.S. military, including body armor and a prototype armored vehicle, and used them to create the equipment needed for his war on crime as Batman. When the League of Shadows eventually followed him back to the city, they intended to finish their duty to destroy it by vaporizing its water supply with a microwave emitter they stole from Wayne Enterprises' shipment cargo after tainting it with a fear-inducing hallucinogenic drug provided by Arkham Asylum's corrupt chief administrator Jonathan Crane, then magnetize the vaporization to the central hub, located beneath Wayne Enterprises, via the monorail system to cause a chain reaction that would release the drug all over the city, making its population tear down their metropolitan home through mass panic in the process.
Batman was able to stop them with the help of Police Det. Sgt. James Gordon by destroying a section of the monorail tracks in front of Wayne Station and causing the train, with Ra's still inside, crash beneath the tower, killing him and saving the city. Finally, at the film's end, the Enterprises came under Bruce control when managed to become a majority shareholder, at which point he installs Fox as the active CEO. Also, his heroism as Batman eventually earned him back respect from Rachel, who told him that taking justice into his own hands would make his father proud, but lost her since she decided not to be with him. As a result Bruce planned to rebuild his father's work just the way it was, brick from brick.
The Dark Knight
Nine months after Bruce takes ownership of the company, Wayne Enterprises's headquarters moved to the building where its Special Projects Division was located. However, because of his nights as Batman, Bruce would fall asleep during the board meetings, causing concern to some of the other members of the board, including the enterprises' M&A law accountant, Coleman Reese. The company's attention eventually drew to the success of some improvents on itself and the city. For example, when it approved the success of a new dynamic growth from a foreign security investments company based in Hong Kong called LSI Holdings, the latter corporation's owner, Mr. Lau, suggested that a powerful joint business should venture between the two corporations. Fox eagerly embraced Lau's proposition, but although LSI indicated powerful economic potential at "8% annual growth", the numbers led him to suspect that much of it was off the charts and probably illegal. Bruce simply excepted it, having suspected that it was the case, and approached a dick ass business deal meant to "get a closer look at their books".
Another success Wayne Enterprises came to be inspired by was a campaign against the organized crime wrecking the company's work to support the city launched to the applause of its citizens by the new Gotham district attorney Harvey Dent, who lent the now Lt. Gordon a petitioned search warrant for five banks with suspected money-laundering to the mafia and asked to collaborate with Batman, so Bruce intruded a date Rachel had with Dent at the Ocelot and offered support for the DA if his chance against the mafia becomes a huge change for the city by throwing a fundraiser in his honor. Unfortunately, the search against the money-laundering banks was outsmarted when the mafia prevented their funds from falling into Dent and Gordon's hands by having Lau, who turned out to be involved in their laundering schemes, relocate the money to a secured location besides a bank and flee back to Hong Kong to avoid Dent's jurisdiction, before Fox could tell him that their business intel was off. Desperate, Dent and Gordon turned to Batman to get him back so that they may use him as a testimony to imprison the mob and cut off all their funds. Batman did so through an elaborate scheme, which involved having Fox equip him with new gadgets developed by the company for a CIA project called Skyhook and smuggle a SONAR system into the LSI building to kill its power, and literally delivers Lau to Gordon outside his unit's headquarters.
Using Lau's offer to testify against the mob for the sake his company and business partners which included from Wayne Enterprises, Gordon and Dent tied up the mafia in a reco case and arrested many of them. All was going well until the Joker, a humorist psychopath hired by the mafia to take out Batman, emerged onto the streets in a chaotic and violent fashion with the gruesome murder of a civilian. The Clown Prince of Crime then began putting out hits on a three people involved in the anti-mafia campaign, including Dent, giving Batman an ultimatum in the process; if Batman didn't reveal himself underneath his mask and turn himself in, then all three of his hits will die along with countless others each and every passing day, even if it included those from the Enterprises. Little did the mafia bosses who hired the Joker, including Sal Maroni and the Chechen, know that he was simply using them to gain control over every level of Gotham's infrastructure through their inside agents and orchestrate his own plans to destroy the city's social democracy and replace it with his own ideals of mindless anarchy and chaos. Dent was however saved by Bruce when the Joker arrived at the fundraiser to kill him personally. However, since Dent was well hidden, the Joker took this advantage throw Rachel out the penthouse window, forcing Batman to jump after and save her while the clown made his escape.
As the psychopathic killing spree continued with the murders of two men who shared Dent's name and a failed assassination attempt on Gotham Mayor Anthony Garcia, Reese became concerned of the money that was being put into the company's R&D department and investigated it in the archives, eventually discovering the blueprints for the Tumbler and confronting Fox about them. Fox reminded him of how powerful Bruce was, and that blackmailing him of his vigilante identity wouldn't work. Luckily, when Dent's false claim of being Batman to lure the Joker out into the open resulted in the scarring of his own face, Rachel's death and the psychopath's escape from the Major Crimes Unit jail with Lau as his hostage to gain control of the mafia's funds, Reese was about to reveal the real identity on TV when the Joker called in proclaiming that the ultimatum against Batman's true identity was no longer required for his regime and gave the people of Gotham a new one; if Reese wasn't killed in an hour, then a one of the city's local hospital's, which he chose as Gotham General since it housed the recovering Dent, will be bombed. As Gordon protected Reese from a a mob of hospital patient relatives trying to kill the lawyer, Bruce saved both their lives intercepting a car about to crash into them.
Later, as the Joker announced his regime to the city and warned its inhabitants to flee if they want no part of it, Fox was assigned by Batman to use an even larger SONAR concept to track the Joker's next threat on the Gotham communications system to his position. Fox agreed but insisted on resigning immediately afterwards. After helping Batman stop the Joker and foil his plans by taking the blame for the murders that the clown had Dent commit, Fox then entered his name as instructed and watched as the machine destroyed itself, thus changing his mind about resigning. His and Wayne Enterprises' faith was rewarded by Bruce.
The Dark Knight Rises
Eight years after Bruce brought Batman into hiding, Wayne Enterprises had descended into bad health after sinking its fortune into a fusion reactor power project, which Bruce subsequently shut down after learning that the reactor's core could be weaponized. This resulted in a lack of profits that led to poor funding for the Wayne Foundation which ended up cutting the funds to St. Swithin's Orphanage. Bruce even became a recluse to society over the loss of Rachel and fear that his down profits will drive him into losing control over his company to a rival pharmaceutical and real estate construction developments company called Daggett Industries. When the latter corporation's owner, John Daggett, hired a professional cat-burglar named Selina Kyle to obtain Bruce's fingerprints from Wayne Manor, Selina was confronted by Bruce, who at first thought she was after his mother's pearl necklace, but escaped with Congressman Byron Gilly in tow.
Gilly's disappearance eventually attracted the attention of the police, who were able to retrieve the congressman, but Gordon made the discovery of Bane, a physicalist militant hired by Daggett to help seize control of Wayne Enterprises, emerging onto the streets in a painful and violent fashion with an attack on the Gotham Stock Exchange meant to for using the fingerprints in a transaction that would bankrupt Bruce. Due to Batman's unwanted return to stop the Respiratory-Masked Brute of Humanity and reluctance preventing the police from stopping the raid made by Gordon's new deputy commissioner Peter Foley, the scheme worked and Bruce was kicked off the Wayne Enterprises board but continued to accept assistance from Fox, who knew he was bankrupted. With the Wayne fortune fraudulently wiped out, a board fight ensued with Daggett attempting to take over the company, proclaiming that he would use it for weapons manufacturing and that soldiers like Bane would be an example of improving the projects to such extent. Little did the Daggett Industries board who hired Bane, including Daggett and Phillip Stryver, know that, as a former member of the League of Shadows, he was simply using them to gain control over every level of Gotham's infrastructure through their activists and orchestrate his own plans to finish Ra's al Ghul's work on destroying Gotham by destroying the city's approving evolution and replacing it with his own ideals of oppressing revolution and pain. However, Bruce made a swift move to stop Daggett from getting his hands on the reactor project by appointing Wayne board member Miranda Tate (secretly Ra's' daughter Talia) to take over the the company in his absence with Fox as its executive president, and she took this opportunity to restart the reactor operation, even though she knew of the dangers.
After killing Daggett and defeating Batman during their first confrontation in his own lair by breaking his back and leaving in an ancient well-like prison in the Middle East known as the Pit (where Bane and Talia were reported to have born in), Bane invaded a Wayne board meeting and took the board to the Advanced Projects Vault, where the fusion reactor was located, first having a Russian nuclear physician named Dr. Leonid Pavel to convert the reactor's core into a nuclear bomb then disconnecting it using the fingerprint analysis from Fox, Miranda and Wayne executive vice president Douglas Fredericks. When the police moved into stop him, Bane used the explosives implanted by Daggett Enterprises cement workers around the city to trap them except Blake, Foley and a few other officers underground.
