SoftBank’s Masayoshi Son is still apologizing for the WeWork debacle.

Speaking at the Lotte New York Palace hotel in Midtown Manhattan on Monday, the SoftBank chairman and CEO reiterated his “regrets” in the troubled office rental company, including a January 2019 investment that gave the Adam Neumann-run company a $47 billion valuation.

After the IPO slopped, SoftBank rescued WeWork at an $8 billion valuation.

As The Post first reported last month, Goldman Sachs had invited its large trader clients to hear from Son on Monday as he seeks help keeping Paul Singer’s activist hedge fund Elliott Management at bay.

Son told the crowd that despite WeWork’s past woes, he is optimistic about it returning to good health in one to three years, said a source who attended the powwow.

He said his famed $100 billion Vision Fund, known for its investments in Uber, Slack and Doordash, has generated a 16 percent annualized rate of return. And he insisted that its failures don’t matter so much because 90 percent of the gains come from 15 percent of the investments.

Elliott Management recently amassed more than a $2.5 billion stake in the Japanese conglomerate and has been pushing for stock buybacks.

Masa did not mention Elliott by name, but said he wants to listen more to the concerns of board members and shareholders.

He also pumped SoftBank’s shares and said it now trades at a big discount.
