MGM Resorts Caps IAC/Diller Voting Power at 25.73% Despite Larger Stake

MGM Resorts International filed an 8-K on April 7, 2026, revealing a voting agreement with IAC Inc. and billionaire Barry Diller that caps their collective voting power at 25.73%, even if their actual ownership exceeds this threshold. The agreement, signed April 3, grants IAC the right to nominate two directors to MGM's board while preventing the entertainment conglomerate from exercising outsized control.

The Deal

Under the voting agreement, IAC, Barry Diller, and their controlled affiliates must vote any shares exceeding 25.73% of MGM's outstanding voting securities proportionally with how other shareholders vote. This effectively neutralizes the voting power of their excess holdings, creating a hard ceiling on their influence regardless of their actual stake size.

The arrangement includes significant board representation rights for IAC, which can designate two qualified directors for nomination to MGM's board. Barry Diller, who serves as both Chairman and Senior Executive of IAC, is already deemed designated to serve on MGM's board under this agreement. If IAC's board seats become vacant, MGM must add IAC-designated directors within one month, subject to regulatory approvals.

The agreement remains in effect until IAC's collective ownership falls below 17.5% of MGM's outstanding voting securities, establishing a meaningful floor for their continued involvement. It would also terminate if MGM's board fails to nominate IAC's designated directors or upon a change of control at MGM.

Strategic Rationale

This voting cap structure represents a sophisticated compromise between accommodating a large strategic investor and protecting minority shareholders from potential control scenarios. For IAC and Diller, accepting the voting limitation allows them to build a substantial economic position in MGM without triggering defensive measures or regulatory scrutiny that typically accompany control positions.

The 25.73% threshold appears carefully calibrated — high enough to provide meaningful influence but below the levels that would grant effective control or trigger Nevada gaming regulatory requirements for controlling shareholders. This percentage also stays clear of the 30% threshold that often triggers mandatory tender offer requirements in various jurisdictions.

For MGM, the arrangement provides stability and prevents hostile takeover scenarios while benefiting from IAC's strategic expertise. IAC brings significant digital media and technology experience that could prove valuable as MGM continues expanding its online gaming and digital entertainment initiatives. The board representation ensures IAC has formal channels to contribute to strategy without dominating decision-making.

The agreement includes an interesting provision for Barry Diller personally: his entities can escape the voting restriction if he no longer serves as IAC's Chairman or Senior Executive and his ownership of IAC voting securities drops below one-third. This suggests the voting cap is tied specifically to Diller's dual role as a major IAC shareholder and MGM investor.

What to Watch

Investors should monitor several key developments following this agreement. First, the identity and qualifications of IAC's second board nominee will signal their strategic priorities for MGM. Tech-focused directors might suggest emphasis on digital transformation, while hospitality veterans could indicate focus on operational improvements.

The actual size of IAC's stake remains a critical unknown. While they clearly own more than 17.5%, the upper bound isn't disclosed. Quarterly 13F filings and potential 13D amendments will reveal whether IAC continues accumulating shares above the 25.73% voting cap, which would indicate confidence in MGM's long-term value despite the voting limitations.

Regulatory considerations, particularly with gaming authorities, will be important to track. While the voting cap helps avoid control-person designation, gaming regulators in Nevada and other jurisdictions will still scrutinize IAC's influence. Any regulatory pushback could complicate the board appointment process or require additional compliance measures.

The market should also watch for potential strategic initiatives arising from this partnership. IAC's portfolio includes digital media and marketplace businesses that could create synergies with MGM's entertainment and gaming properties. Joint ventures, technology partnerships, or customer acquisition collaborations could emerge from this closer relationship.

Finally, this structure could influence future M&A activity at MGM. While the agreement doesn't explicitly restrict transactions, having a 25.73% voting bloc with board representation creates a meaningful constituency that management must consider in any strategic decisions. The change-of-control termination provision suggests IAC negotiated protection against being frozen out of major transactions.

This voting agreement reflects the evolving nature of shareholder activism and strategic investing, where negotiated governance arrangements replace hostile tactics. For MGM shareholders, it provides a framework for IAC's involvement that balances the benefits of an engaged, experienced investor with protections against unilateral control.
