Digital World had been hoping that the U.S. Securities and Exchange Commission (SEC), which is reviewing its disclosures on the deal, would have given its blessing by now.Register now for FREE unlimited access to Reuters.comRegisterDigital World Chief Executive Patrick Orlando told a special meeting of his shareholders on Tuesday he would push back to noon on Thursday the deadline for the vote on extending the life of the SPAC by 12 months.Digital World needs 65% of its shareholders to vote in favor of the proposal, but the support as of late Monday fell far short, Reuters reported. Digital World did not disclose the margin on Tuesday. read more Digital World shares ended trading in New York on Tuesday down 11.4% at $22.13.Digital World is set to liquidate on Thursday and return the money raised in its September 2021 initial public offering to shareholders unless action is taken.Digital World shareholders had been given more than two weeks to vote on the SPAC’s extension and it is unclear if two additional days will make a difference. Most Digital World shareholders are individuals and getting them to vote through their brokers has been challenging, Orlando said last week.Digital World said in a statement that if its shareholders do not approve the one-year extension on Thursday, its management plans to exercise its right to extend the life of the SPAC by three months unilaterally. The SPAC managers will lend $2.875 million to the SPAC as part of the arrangement, Digital World said.The SPAC managers have the right to unilaterally extend the life of the SPAC one more time, till March. It is unclear whether this would provide enough time for regulators to reach a conclusion on whether to allow the deal to proceed.A TMTG spokesperson said the company will continue cooperating with all stakeholders on the merger and that it hoped “the SEC staff will expeditiously conclude its review free from political interference.”An SEC spokesperson did not immediately respond to a request for comment.Trump appeared to manage expectations for the deal with a post over the weekend on Truth Social: “I don’t need financing, ‘I’m really rich!’ Private company anyone???”Digital World has disclosed that the SEC, the Financial Industry Regulatory Authority and federal prosecutors have been investigating the deal with TMTG, though the exact scope of the probes is unclear.The information sought by regulators includes Digital World documents on due diligence of potential targets other than TMTG, relationships between Digital World and other entities, meetings of Digital World’s board, policies and procedures relating to trading, and the identities of certain investors, Digital World has said.PIPE AT RISKIf the deal is completed, TMTG would receive $293 million that Digital World has on hand plus $1 billion committed from a group of investors in the form of a private investment in public equity (PIPE).The PIPE is scheduled to expire on Sept. 20 unless the deal is completed. Investment bankers for Digital World have been reaching out to investors in the last few weeks to gauge their interest in extending the PIPE, a person familiar with the matter said.It is unclear how TMTG is getting by without access to Digital World’s funding. It raised $22.6 million through convertible promissory notes last year and another $15.4 million through bridge financing in the first quarter. The agreement with Digital World caps the indebtedness that TMTG can assume prior to the deal closing at $50 million.Digital World has said it believes TMTG will have “sufficient funds” until April 2023. TMTG said last week that Truth Social is “on strong financial footing” and would begin running advertisements soon.Trump started using Truth Social in April, two months after it launched on Apple Inc’s (AAPL.O) app store. He has more than 4 million followers – a fraction of the 89 million he had on Twitter Inc (TWTR.N) before he was banned over his role in the January 2021 U.S. Capitol riots by thousands of his supporters.Register now for FREE unlimited access to Reuters.comRegisterReporting by Echo Wang and Helen Coster in New York; Editing by Richard Chang and Jonathan OatisOur Standards: The Thomson Reuters Trust Principles.
