AI Financial Corporation, formerly known as ALT5 Sigma and backed by World Liberty Financial, has agreed to acquire Block Street Corp. in a transaction valued at up to $43 million. The deal, structured as a stock issuance plus performance-linked warrants, was signed under a Stock Exchange Agreement dated April 20, 2026, and disclosed in an SEC Form 8-K filed April 24, 2026.
Under the agreement, AI Financial will issue 12,670,257 common shares to Block Street’s four owners. The initial share issuance is valued at $12 million based on the Nasdaq minimum price.
In addition to the upfront stock, AI Financial will grant two five-year pre-funded warrant tranches that can increase the total consideration to as much as $43 million if Block Street meets specified performance targets.
The earnout structure is contingent: Block Street must reach $20 million in trailing four-quarter net revenue and $8 million in trailing four-quarter modified operating income before the warrant tranches vest. If those thresholds are not met, the transaction would remain limited to the $12 million in upfront shares.
The share and warrant issuances were structured as private offerings under Section 4(a)(2) of the Securities Act. AI Financial disclosed the terms in its SEC filing dated April 24, 2026.
The buyer was still operating as ALT5 Sigma Corporation when it signed the Block Street agreement on April 20, 2026. Two days later, ALT5 announced plans to rebrand as AI Financial Corporation and change its Nasdaq ticker to AIFC. The rebrand took effect on April 29, 2026, when trading began under the AIFC ticker, replacing ALT5 Sigma’s ALTS symbol.
AI Financial’s April 22 announcement stated that it does not currently offer AI-enabled financial infrastructure despite the AI-focused branding.
AI Financial’s link to the Trump family runs through World Liberty Financial, which led ALT5’s $1.5 billion financing round in August 2025. Eric Trump joined ALT5’s board of directors.
The vesting requirements—$20 million in trailing four-quarter net revenue and $8 million in trailing four-quarter modified operating income—indicate that AI Financial is tying a significant portion of the deal value to measurable operating performance rather than speculative asset value.
The structure also limits downside for AI Financial: if Block Street does not meet the thresholds, the company would pay only the $12 million upfront share consideration, with the additional $31 million tied to the warrant tranches remaining contingent.
The acquisition is occurring amid subdued crypto sentiment. The Fear & Greed Index stands at 29, which is categorized as “Fear.” Because neither AI Financial nor Block Street has a liquid, publicly traded crypto token, direct market reaction may be harder to gauge through token prices.
As a Nasdaq-listed equity, AI Financial’s stock—now under the AIFC ticker—will likely be the primary indicator of investor response. The article notes that the stock experienced volatility around the initial SEC filing, though micro-cap equity moves can be influenced by thin liquidity as well as sentiment.
AI Financial Corporation (formerly ALT5 Sigma Corporation) is the buyer. It trades on Nasdaq under the ticker AIFC as of April 29, 2026. World Liberty Financial led the company’s $1.5 billion financing in August 2025, and Eric Trump serves on its board.
The deal is valued at up to $43 million, consisting of $12 million in upfront shares plus two performance-linked warrant tranches valued at $15 million and $16 million, respectively.
The Stock Exchange Agreement was signed on April 20, 2026, and the initial shares were issued. The two warrant tranches have not yet vested and require Block Street to achieve $20 million in trailing four-quarter net revenue and $8 million in trailing four-quarter modified operating income.
The article states that limited public information is available about Block Street Corp.’s specific operations. The performance milestones suggest the company is expected to be a revenue-generating business, but additional details about its products or market position were not widely disclosed beyond the SEC filing.
The connection is indirect but material. World Liberty Financial, associated with the Trump family, led ALT5’s $1.5 billion financing round in August 2025, and Eric Trump joined the board. The company’s subsequent acquisitions, including the Block Street deal, are funded in part by that capital base.
