[Form 4] Riot Platforms, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Amendment No. 5 to Schedule 13D discloses that the Silver Lake–affiliated reporting persons (Global Blue Holding L.P., SL Globetrotter L.P., SL Globetrotter GP Ltd., Silver Lake Technology Associates III Cayman L.P. and Silver Lake (Offshore) AIV GP III Ltd.) have tendered all of their equity interests in Global Blue Group Holding AG (“GB”) in connection with the cash tender offer launched by Shift4 Payments, Inc. and its Swiss merger subsidiary.

The offer, which commenced on 21 March 2025 and expired one minute after 11:59 p.m. (NYC time) on 2 July 2025, met all conditions. The Silver Lake vehicles tendered:

• 34,871,499 ordinary shares held by Cayman Holdings at $7.50 per share
• 4,939,137 Series A preferred shares (convertible into ordinary shares) at $10.00 per share
• 91,230,811 ordinary shares held by Globetrotter at $7.50 per share
• 11,970,487 Series A preferred shares held by Globetrotter at $10.00 per share

In addition, 2,701,935 Global Blue warrants (Cayman Holdings) and 6,548,415 warrants (Globetrotter) were cashed-out and are no longer exercisable. As a result of these transactions, the reporting persons now report 0 shares beneficially owned (0.0% of the class) and thereby cease to be 5% holders as of 3 July 2025.

Following completion of the offer, director Joseph Osnoss resigned from the Global Blue board. The filing attaches an amended Annex A listing directors of the Silver Lake general partners and adds Exhibit 99.1 containing that information.

This amendment is limited to updating ownership, identity disclosures and purpose-of-transaction details; all other information in prior filings remains unchanged.

Positive

• Completion of Shift4 tender offer provides shareholders with immediate cash at $7.50 per ordinary share and $10 per Series A preferred, crystallising value.
• Over 142 million shares and 9.25 million warrants were tendered, eliminating a sizable private-equity overhang and simplifying the cap table.

Negative

• Silver Lake’s exit removes a long-term strategic investor, potentially reducing institutional support and signalling full control by Shift4.
• Resignation of director Joseph Osnoss creates short-term governance transition risk until a new board structure is confirmed.

Insights

Financial Analyst

TL;DR Shift4’s tender offer closed; Silver Lake tendered 100% of its 142 M+ shares & warrants, exiting Global Blue at $7.50/$10 cash.

Impact assessment: The transaction removes a large private-equity overhang and confirms a full change-of-control at pre-negotiated cash prices. The roughly US$1.2 billion gross proceeds to Silver Lake (142 M ordinary-share equivalents × blended price ≈ $8.4) suggest a clean exit and validate the valuation underlying Shift4’s strategic expansion into tax-free shopping payments. For remaining public investors, liquidity is now concentrated in Shift4’s hands, and the free float will shrink sharply once merger mechanics complete, implying potential delisting down the line. While price terms were announced in February, the filing provides final confirmation that all shares were accepted and paid. Governance shifts are underway—Joseph Osnoss’s resignation foreshadows a reconstituted board aligned with Shift4.

Corporate Governance Expert

TL;DR Silver Lake’s exit ends its board representation; control passes to Shift4, triggering governance realignment.

The amendment documents the formal relinquishment of equity and board influence by Silver Lake. With zero ownership, its affiliated director resigned, eliminating potential conflict-of-interest issues during post-merger integration. The Schedule 13D amendment also satisfies Section 13(d) requirements by noting cessation of 5% ownership. Investors should monitor subsequent filings for board re-composition, potential squeeze-out or listing status changes. From a compliance standpoint, the clean break reduces related-party complexities in future disclosures.
