The activist short-selling landscape saw renewed activity this week as firms targeted two high-profile, relatively recent market entrants. Blue Orca Capital has trained its sights on EquipmentShare (NASDAQ: EQPT), while Iceberg Research has published a bear case against the nuclear energy startup Deep Fission (NASDAQ: FISN). Blue Orca’s report centers on EquipmentShare’s "OWN Program," an asset-light rental structure where third-party investors purchase construction equipment and lease it to the company. The short seller alleges that this $5.5 billion fleet carries an undisclosed 10% first-loss guarantee. If accurate, this creates roughly $500 million in potential exposure against only $55 million in tangible book value. Furthermore, the report highlights that nearly 40% of the co-founders' holdings have been pledged against margin loans, a common forensic red flag suggesting potential personal liquidity constraints or increased pressure to maintain stock price performance. Simultaneously, Iceberg Research has targeted Deep Fission, characterizing the company as a "busted IPO." The firm’s analysis disputes the company’s cost-efficiency projections, estimating that the cost of energy for the firm's proposed underground small modular reactors (SMRs) would be $289 per megawatt-hour—vastly higher than the $50–70 range reportedly pitched to investors. Iceberg also questions the credibility of the company's purported "industry's largest pipeline," suggesting an immediate capital shortfall of approximately $350 million. From a forensic perspective, both reports highlight a recurring theme in the current market cycle: the scrutiny of high-growth companies that utilized the IPO window to finance capital-intensive business models. For investors, the takeaway lies in the discrepancy between "asset-light" narrative reporting and the underlying capital commitments—such as EquipmentShare’s guarantee structures—that may not be immediately apparent in standard headline metrics. Both companies have pushed back against the claims, with EquipmentShare stating that the report mischaracterizes its business operations. ## Key Takeaways - Blue Orca alleges EquipmentShare carries $500M in undisclosed liabilities via its "OWN Program" fleet guarantees. - Iceberg Research claims Deep Fission's energy production costs are nearly 5x higher than investor projections. - Both reports underscore the forensic risk of "asset-light" narratives masking significant capital-intensive commitments. ## Sources - The Bear Cave — Analysis of activist short reports including Blue Orca and Iceberg Research, September 27, 2026.
