Transformers: Age of Extinction is a 2014 science fiction action film based on Hasbro's Transformers toy line. It is the sequel to Transformers: Dark of the Moon (2011) and the fourth installment in the Transformers film series. Like its predecessor, the film was directed by Michael Bay and written by Ehren Kruger. It stars Mark Wahlberg and Stanley Tucci, with Kelsey Grammer, Nicola Peltz, Jack Reynor, Sophia Myles, Bingbing Li, Titus Welliver, and T.J. Miller in supporting roles. It does not feature the original human cast from the previous three films, instead introducing a new human cast as well as new Transformers, including the Dinobots. In the film, inventor Cade Yeager teams up with Optimus Prime and the surviving Autobots to investigate a manhunt involving Transformers for their hostility.

The film was released in the United States on June 27, 2014, by Paramount Pictures. It received negative reviews from critics, criticizing its pacing, runtime, direction, plot, and dialogue. The film was a box office success, grossing $1.105 billion worldwide against a $210 million production budget, making it the highest-grossing film of 2014, the only film in 2014 to gross over $1 billion, and the tenth-highest-grossing film of all time at the time of its release. It was followed by a sequel, Transformers: The Last Knight in 2017.

Plot Sixty-five million years ago, an alien race known as the "Creators" used devices called Seeds to cover Earth with a metallic alloy called "Transformium", wiping out the dinosaurs in the process. In the present day, K.S.I. Industries is using Transformium to build Transformer drones.

Five years after the Battle of Chicago, the Autobots are hunted down by Cemetery Wind, a rogue CIA black-ops division led by opportunistic rogue intelligence operative Harold Attinger, who believes all Transformers are dangerous and must be destroyed. Lockdown, a Cybertronian assassin and bounty hunter working for the Creators, is tasked with finding Optimus Prime. In exchange, he gives Attinger a Seed if his division captures Optimus. Lockdown locates and kills Ratchet when he refuses to give up Optimus's location.

Badly damaged in Mexico City, Optimus hides in Texas and is found by Cade Yeager, a financially struggling inventor and single father. While his teenage daughter Tessa and business partner Lucas Flannery urge him to turn Optimus in, Cade instead fixes him. Hoping to collect an advertised reward, Lucas alerts the authorities, and James Savoy, Attinger's field commanding operative, attacks the Yeager farm. Still, Optimus, and Tessa's secret boyfriend, Irish rally car driver Shane Dyson, rescue the family. During the pursuit, Lucas is killed by one of Lockdown's grenades. Optimus summons the surviving Autobots – Bumblebee, Hound, Drift, and Crosshairs. Using a stolen CIA drone, Cade discovers K.S.I.'s involvement with Cemetery Wind and the attacks on the Autobots.

Infiltrating K.S.I.'s headquarters in Chicago, Cade discovers the dead Autobots and Decepticons being melted down to make Transformer drones—the K.S.I. CEO Joshua Joyce is in league with Attinger to revolutionize global defenses and improve human society using the Seed to make more Transformium. He has also used the captured Brains and Megatron's head to create prototype Transformer soldiers, Galvatron and Stinger. The Autobots storm the building and destroy the laboratory, but they soon leave after Joshua declares they no longer need them. Attinger forces Joshua to deploy Galvatron and Stinger to capture the Autobots. As Galvatron battles Optimus, he gets autonomously freed from control. Suddenly, Lockdown arrives and abducts both Optimus and Tessa while Galvatron retreats.

While Lockdown's large prison spacecraft hovers over Chicago to hand over the Seed, Cade, Shane, and the Autobots sneak on board to rescue Optimus and Tessa. They hijack a smaller ship carrying other Transformers called the Dinobots just before Lockdown leaves Earth. The Autobots learn that Galvatron is Megatron reincarnated, plotting to use the Seed and the Transformer drones to conquer the world, and that KSI plans to use the Seed in the Mongolian desert to create vast amounts of usable Transformium. Cade informs Joshua, who agrees to hand over the Seed. Galvatron reactivates himself and takes control of the drones, organizing them into a new Decepticon army. A battle follows in Hong Kong between the Autobots, Cemetery Wind, and the Decepticons. During the fight, Cade sends Savoy plummeting to his death while Optimus frees the Dinobots and wins their allegiance through trial by combat, becoming essential to the Autobots' victory.

Lockdown returns to recapture Optimus and the Dinobots, using a large magnet to cause destruction. After disabling the magnet, Optimus fights Lockdown. In the ensuing duel, Optimus kills Attinger to save Cade, but the distraction allows Lockdown to pin Optimus down with his sword. Cade ends up fighting Lockdown one-on-one while Tessa and Shane use a tow truck to free Optimus, who kills Lockdown before destroying the remaining Decepticons with Lockdown's grenade. Galvatron retreats, vowing to return. Optimus asks the Autobots to protect the Yeagers, then flies away into space with the Seed, sending the Creators a message that he is coming for them.
