On June 13, 2016, it was announced that 4Minute had made the decision to disband.
Hyuna was the only member of the group to renew her contract with Cube Entertainment.
Following the group's disbandment, she resumed her activities as a solo artist, with the release of her fifth mini album A'wesome and its title track "How's This?" (
Korean: 어때?),
on August 1, 2016.
Behind-the-scenes footage of Hyuna's album's preparation was featured on her solo reality program HyunA X19.
The album topped nine local music charts upon release.
She embarked on her first solo Asia tour soon after.
To mark her tenth anniversary, Hyuna announced a fan-meeting tour in North America.
She visited ten cities in total during February 2017.
On April 3, 2017, Cube Entertainment confirmed that she and Pentagon members Hui and E'Dawn were set to debut in May as new sub-unit, Triple H. On April 4, Cube TV debuted a new reality TV program called Triple H Detective Agency.
Hyuna released her sixth mini-album Following and its title track "Babe" on August 29, 2017.
On December 2, 2017, the rapper attended the 2017 Melon Music Awards, where she premiered the single "Lip & Hip".
It was officially released two days later.

On August 2, 2018, photos of Hyuna with Pentagon's E'Dawn were released.
Cube Entertainment denied rumors that they were dating, however, she and E’Dawn held an interview with Yeonhap News later that day, admitting to their relationship which began in May 2016, after they had got to know each other through their project group Triple H promotions.
The company responded to Hyuna's confirmation of the dating rumors by cancelling all previously planned performances for Triple H, on-air appearances and fan events including a fan meet-up that was scheduled on the next day.
Fans were divided in reactions to the event, with some calling for E'Dawn to be removed from Pentagon, and others focusing on how the company mistreated her and E'Dawn after releasing the scandal, rather than on their relationship.
On September 13, Cube Entertainment announced that they would be terminating their contracts, citing that they could not "maintain trust" with them.
However, the company announced that they would still remain in discussion with both of them until further notice.
Cube Entertainment cited “loss of trust” as a reason saying "After much deliberation, we've concluded that the trust between the company and the artists had been damaged to a degree that it cannot be restored, leading us to believe expulsion is necessary," in its official statement.
On October 15, Cube Entertainment officially confirmed Hyuna's departure.

On January 27, 2019, she signed with P-Nation, a new agency founded by Psy since he left YG Entertainment in May 2018.
On November 5, 2019, she released a single titled "Flower Shower", her first release under P-Nation.
