[SCHEDULE 13D] International Money Express, Inc. SEC Filing

Rhea-AI Filing Summary

Magnetar-affiliated reporting persons disclosed beneficial ownership of 1,583,685 shares of International Money Express Inc. (IMXI), representing approximately 5.33% of the outstanding Class A common stock. The shares are held across four Magnetar accounts: PRA Master Fund, Systematic Master Fund, Relative Value Master Fund and two managed accounts. The reporting persons state they purchased the shares from fund assets for a total cost of $23,349,641.67. The acquisition was made after a public announcement of a merger under which IMXI shareholders are to receive $16.00 per share in cash upon consummation. The filers reserve the right to buy or sell additional securities and otherwise change their intentions.

Positive

• Transparency: The filing clearly discloses ownership structure, exact share counts, and funding amount of $23,349,641.67.
• Clear purpose: The reporting persons state the acquisition was to receive the announced $16.00 per share merger consideration.

Negative

• No intent to influence governance: The filers state they have no plans for actions or events that would change company control, which limits potential shareholder engagement.
• Shared control only: The reporting persons report shared voting and dispositive power, not sole control, limiting direct influence over outcomes.

Insights

Securities Analyst

TL;DR: A hedge-fund affiliate amassed a meaningful minority stake (5.33%) in IMXI ahead of a $16 cash merger, funded from fund assets totaling $23.35M.

The filing shows coordinated beneficial ownership by Magnetar entities and the manager, indicating consolidated voting and dispositive influence over the reported shares. The stake size is large enough to be material to governance discussions but remains minority and non-control in nature. The purpose is explicitly stated as positioning to receive merger consideration, with flexibility to trade further. Investors should note the stake was acquired from fund assets and includes shared voting/dispositive power.

Corporate Governance Expert

TL;DR: Magnetar entities disclose shared control of 5.33% of IMXI for merger consideration; no activist plans disclosed.

The Schedule 13D identifies the organizational structure linking the reporting persons and clarifies shared voting/dispositive power over the 1,583,685 shares. The filing contains no proposals or plans to effect governance changes and references only the merger consideration as the acquisition purpose. The joint filing agreement and power of attorney exhibits reinforce coordination among the filers. Materiality is moderate given the stake size and the announced $16-per-share merger consideration.
