Ten separate activist disclosures hit SEC servers between April 21 and April 25, spanning $2.1 billion in reported stakes across ten public companies. Corebridge Financial, Vail Resorts, Empire State Realty Trust, General Dynamics, StoneCo, International Seaways, Seadrill, BrightSpire Capital, Elastic, and Navigator Holdings each received 13D filings naming activist positions above the 5% reporting threshold. The clustering is unusual. Activist campaigns typically scatter across quarters. This batch landed within ninety-six hours.
Erez Asset Management, led by Bruce Schanzer, disclosed a 5.8% stake in Empire State Realty Trust, the Manhattan office and retail landlord that controls the Empire State Building and eleven other properties. The filing names intention to engage management on capital allocation and asset monetization. Schanzer previously ran Spirit Realty Capital before its $9.3 billion sale to Realty Income in 2023. His pattern is operational REITs with undermonetized trophy assets. ESRT shares closed April 25 at $9.14, down 22% year-to-date, trading at a 34% discount to consensus net asset value. Office vacancy in Midtown Manhattan sits at 16.7%, the highest since 2021, but ESRT's Empire State Building runs 92% occupied due to observatory revenue and brand premium.
Corebridge Financial, the AIG-spun life insurance and retirement specialist, saw Elliott Investment Management file a 13D for an undisclosed stake size. Elliott has targeted financial services three times in the past eighteen months, each time pressing for buybacks or separation of undervalued units. Corebridge trades at 0.68x book value despite a 15.2% return on equity and $4.1 billion in trailing twelve-month free cash flow. The company authorized a $3 billion buyback in February but has repurchased only $740 million through March. Elliott's letter will likely name the pace inadequate.
Vail Resorts caught a filing from an undisclosed activist naming board composition and operational efficiency. Vail owns 42 ski resorts across North America and Australia, including Whistler Blackcomb and Park City. Revenue per skier visit rose 6.2% in the most recent quarter, but total skier visits declined 4.1%, pressured by poor early-season snowfall in the Rockies and Epic Pass pricing fatigue. The stock trades at $177, down 31% from its 2021 peak, and at 14.1x forward earnings, below its five-year average of 19.3x. The activist's angle is unclear but likely targets either real estate monetization or marketing spend, which hit $287 million in fiscal 2024, up 19% year-over-year.
General Dynamics, StoneCo, and the maritime trio—International Seaways, Seadrill, Navigator Holdings—round out the list. General Dynamics, the defense contractor with $49 billion in trailing revenue, rarely draws activist attention due to its operational discipline and 92% contract renewal rate with the Department of Defense. The filing is from a smaller fund and likely targets share buyback acceleration rather than operational change. StoneCo, the Brazilian payments processor, has seen three activists circle since its 73% drawdown from 2021 highs. The company trades at $11.40, below its $24 IPO price, despite returning to profitability in Q4 2024.
The maritime cluster is notable. International Seaways, Seadrill, and Navigator Holdings all operate in energy logistics, a sector where day rates have compressed 18-22% since mid-2023 as crude tanker supply normalized post-sanction volatility. Activists in this space typically push for fleet rationalization or merger. Seadrill, the offshore driller, emerged from bankruptcy in 2021 and trades at $32.80, near its post-restructuring lows. Navigator Holdings operates 38 liquefied gas carriers and has $1.1 billion in debt against a market cap of $890 million. The activist here is likely positioning for either a refinancing event or asset sale.
Operators should watch for proxy filings in the next 45-60 days. Activists filing 13Ds in late April are preparing for June annual meetings or setting up for fall proxy fights. ESRT's annual meeting is scheduled for June 12. Corebridge's is June 18. Vail has not yet announced its date but typically holds meetings in mid-September. Elliott's median time from 13D to public letter is 23 days. Schanzer's Erez filed on ESRT April 22 and has not yet issued a public statement, suggesting either private engagement or imminent public pressure.
The clustering itself is the signal. Ten filings in five days suggests either: coordinated timing to avoid individual media cycles, or a shared thesis that Q1 earnings season exposed exploitable misallocations. Either way, the next $400-600 million in incremental buyback authorizations or asset sale announcements will clarify whether boards were already moving or whether activists forced the hand. The maritime names bear watching. When three activists file on the same subsector within a week, consolidation or distress is already priced in private rooms.
The takeaway
Ten activist 13Ds in five days. $2.1B disclosed. ESRT, Corebridge, Vail named. Next 45 days will show who pre-empted.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
