Company Responds to Media Reports

ALT5 Sigma publicly denounced X, rejecting media coverage by Coinpedia and The Information. These reports claimed that Jon Isaac was an executive in the company and that the SEC had initiated an investigation into its financial transactions.

ALT5 Sigma has been made aware of reports in the press and on social media. For the record: Jon Isaac is not –– and never was –– the President of ALT5 Sigma and he is not an advisor to the company. The company has no knowledge of any current investigation regarding its activities…

The company made clear that Isaac has not worked as president or advisor and that it is unaware of any investigation into or involving him or ALT5. The statement was made to straighten out the record after a misunderstanding regarding his position in the firm’s recent capital activities.

Jon Isaac Clarifies His Position

Jon Isaac too refuted the allegations in an independent post on X. He said he is not investigated himself, never held a leadership position at ALT5 Sigma. Isaac aligned himself as the CEO of Live Ventures which is listed in Nasdaq market under the ticker symbol LIVE.

He admitted to having been involved in the predecessor to ALT5 Sigma and indicated that he continued to support the company as a shareholder. Isaac further said any regulatory matters related to Live Ventures had been discussed within the public realm.

It is unclear what role Isaac played, but in December, he signed a two-year consulting deal with ALT5 that would start in March 2024. He was issued a promissory note for $540,000, which was later converted to more than 465,000 shares of the company and interest. Reports were that he took part in weekly management calls on financial and strategic issues.

Political Ties Raise Eyebrows

The Trump association with Sigma and World Liberty Financial has aroused political interest. Eric Trump also became a member of the board of directors of ALT5 Sigma at the time of major funding. Zach Witkoff, son of Trump associate Steve Witkoff and WLFI CEO, was appointed chairman of the board at ALT5.

Democratic senators Richard Blumenthal and Maxine Waters have doubted possible conflicts of interest. That inquiry faulted the company over its ties to Trump-related digital asset ventures. Here, the legal department of ALT5 Sigma has rejected such objections as baseless. Shares of the company declined drastically after this controversy, where the amount dropped on Tuesday afternoon at 10.48 to 5.39 in early Wednesday trading.
