7 short reports in one week: shells, sham credits, and fake orders
Weekly Wrap Up: Sunday, May 24, 2026
It was a relentless week on the short side, with research firms publishing back to back across nearly every sector. The bigger conversation came from Carson Block, who used a Financial Times interview to warn that the AI investment boom could be setting up the next financial crisis, arguing the frenzy has blurred the line between smart money and dumb money. That tension ran through the week's reports, several of which targeted companies riding AI and momentum narratives. The market reaction was a mixed bag. Some names shrugged off the allegations and finished the week higher, while others took real damage, a reminder that being right on the research and being right on the timing are two very different things. Here is everything that crossed our desk.

Fugazi Research Short Report on MMTec, Inc.
| Metric | Price | Change |
|---|---|---|
| Close (Day Before) | $4.85 | — |
| Low (Report Date) | $4.25 | -12.4% |
| Close (Report Date) | $5.27 | +8.7% |
| Close (End of Week) | $6.29 | +29.7% |
Stock Price Impact: MTC dropped to $4.25 intraday, down 12.4%, but reversed hard and closed the report date up 8.7%. The squeeze continued all week, with shares finishing at $6.29, up 29.7% from the pre-report close. The move underscores Fugazi's own thesis that the stock trades on engineered momentum rather than fundamentals.
About The Company: MMTec, Inc. is a British Virgin Islands holding company operating through subsidiaries in Hong Kong, Beijing, and New York. Its only revenue-generating entity is MM Global Securities, a FINRA-registered introducing broker. The company has never generated cash from operations and trades on NASDAQ after surviving a delisting determination in October 2025.
Key Points from the Report:
- Fugazi alleges MTC is a near-revenue-less shell, with FY2025 revenue of $807,500 against a market cap near $495 million, a roughly 605x sales multiple.
- MM Global, the sole revenue source, was censured and fined $450,000 by FINRA for failing to detect potential market manipulation in an affiliate's stock.
- A March 2023 convertible note carries death-spiral mechanics; one conversion issued 74.4 million new shares and grew the count 295%.
- The report flags two reverse splits totaling a 1-for-80 ratio and warns a third is likely given ongoing Nasdaq bid-price risk.

Fuzzy Panda Research Short Report on T1 Energy Inc.
| Metric | Price | Change |
|---|---|---|
| Close (Day Before) | $7.00 | — |
| Low (Report Date) | $6.08 | -13.1% |
| Close (Report Date) | $6.88 | -1.7% |
| Close (End of Week) | $8.08 | +15.4% |
Stock Price Impact: TE sank as much as 13.1% intraday before recovering to close the report date down just 1.7%. The stock then rallied through the rest of the week, finishing at $8.08, up 15.4% from the pre-report close. The market shrugged off the allegations despite the depth of the underlying findings.
About The Company: T1 Energy is a US solar module manufacturer that runs its G1 factory on technology licensed from Chinese producer Trina Solar, which accounted for 99.9% of Q1-2026 revenue. Its economics depend on Section 45X tax credits. The company is also building a solar cell factory, G2, in Rockdale, Texas.
Key Points from the Report:
- Fuzzy Panda alleges T1's claimed compliance with foreign-entity sourcing rules is a sham, based on an IP transfer to a Singapore entity, Evervolt, with deep documented ties to Trina Solar.
- The firm links Evervolt to Chinese state-owned CETC and to entities on the US Commerce Department's anti-dumping list.
- Without 45X credits, the report estimates operating margins swing from positive 6% to negative 31%, with $224 million in 2026 credits at risk.
- Fuzzy Panda cites active DOJ and SEC subpoenas and a likely earnings restatement removing $41.4 million in booked credits.

Kerrisdale Capital Short Report on Everspin Technologies
| Metric | Price | Change |
|---|---|---|
| Close (Day Before) | $33.35 | — |
| Low (Report Date) | $29.50 | -11.5% |
| Close (Report Date) | $31.72 | -4.9% |
| Close (End of Week) | $33.68 | +1.0% |
Stock Price Impact: MRAM fell as much as 11.5% intraday and closed the report date down 4.9%. The decline did not hold, and the stock recovered to finish the week at $33.68, up 1.0% from the pre-report close. The bounce reflects how hard speculative momentum names can be to break with a valuation thesis alone.
About The Company: Everspin Technologies is a niche semiconductor maker that develops Magnetoresistive Random Access Memory, a persistent memory technology used in industrial settings such as railway signaling and aircraft black boxes. Its largest single end market is casino gaming and slot machines. The company carries a market cap near $900 million.
Key Points from the Report:
- Kerrisdale argues Everspin has no meaningful AI exposure, unlike DRAM and HBM suppliers seeing step-function demand.
- Revenue has been stuck in the roughly $50 to $65 million range for much of the past five years.
- Shares are up about 300% in six weeks, trading at roughly 10x 2027E sales and 38x 2027E EBITDA, with fair value pegged at $14, about 60% downside.
- The report notes the CEO, CFO, and two directors sold stock into the rally.

Grizzly Research Short Report on Ottobock SE & Co. KGaA
Ottobock trades on the Frankfurt Stock Exchange and is not tracked in our US price feed. Public reporting indicates shares fell roughly 11% on the report date to about €53.30.
Stock Price Impact: Ottobock shares dropped about 11% on the report date, to roughly €53.30, one of the sharpest single-day reactions of the week. The IPO priced at €66 per share in October 2025, so the stock was already trading below its debut before Grizzly's report added further pressure.
About The Company: Ottobock SE & Co. KGaA, founded in 1919 in Duderstadt, Germany, is a global market leader in prosthetics, orthotics, and mobility solutions. It IPO'd in Frankfurt in October 2025 at a €3.8 billion equity valuation. Controlling shareholder Hans Georg Näder holds roughly 81% of shares and full voting control through a KGaA structure.
Key Points from the Report:
- Grizzly alleges Näder has pledged all of his Ottobock shares as collateral for a PIK loan that the firm estimates will require roughly €2.36 billion in repayment by 2030.
- The report claims Näder's holding vehicle hit negative equity by end-2024 after extracting more from Ottobock than it earned for over a decade.
- Grizzly estimates an undisclosed Russia business accounts for roughly 35.1% of net income after the company folded regional reporting into "EMEA."
- German accounting experts consulted by Grizzly called Ottobock's R&D capitalization, 9.6x its closest peer relative to assets, impermissible.

Manatee Research Short Report on Amprius Technologies, Inc.
| Metric | Price | Change |
|---|---|---|
| Close (Day Before) | $15.48 | — |
| Low (Report Date) | $14.25 | -7.9% |
| Close (Report Date) | $15.07 | -2.7% |
| Close (End of Week) | $16.03 | +3.6% |
Stock Price Impact: AMPX dipped 7.9% intraday and closed the report date down 2.7%. The pullback was brief, and the stock climbed to finish the week at $16.03, up 3.6% from the pre-report close. With shares up roughly 490% over the prior year, the report did little to slow the run.
About The Company: Amprius Technologies is a Fremont, California developer of high energy-density lithium-ion batteries built on silicon anodes. Its SiMaxx platform serves defense customers, while its SiCore platform, sourced largely from Chinese supplier Berzelius, drives revenue growth. FY2025 revenue was about $72 million against a market cap near $2.2 billion.
Key Points from the Report:
- Manatee alleges Berzelius, supplying roughly 36% of cost of revenue, is a concealed related party effectively owned through entities tied to founder and former CEO Kang Sun.
- The firm estimates announced light-electric-vehicle orders of over $20 million generated only about $12.4 million in reconcilable revenue.
- A March 2026 $21 million order described a cylindrical cell with specifications Manatee says do not exist in Amprius's current product catalog.
- The report flags reliance on a "Korea Battery Alliance" partner, Eurocell, that was criminally convicted and shows zero production.

| Metric | Price | Change |
|---|---|---|
| Close (Day Before) | $20.02 | — |
| Low (Report Date) | $18.00 | -10.1% |
| Close (Report Date) | $20.71 | +3.4% |
| Close (End of Week) | $17.70 | -11.6% |
Stock Price Impact: LIFE fell 10.1% intraday before rebounding to close the report date up 3.4%. The recovery did not last. Shares slid through the rest of the week to finish at $17.70, down 11.6% from the pre-report close, the clearest delayed reaction of the week.
About The Company: Ethos Technologies is a venture-backed, San Francisco-based life insurance company founded in 2016 that markets itself as a technology-driven, direct-to-consumer platform. It acts as an underwriter, administrator, and distributor, says it has activated over 500,000 policies, and employs more than 600 people across San Francisco and Bengaluru.
Key Points from the Report:
- The Bear Cave characterizes Ethos as essentially a life insurance lead-generation business that spent roughly $100 million on TV, radio, and Facebook advertising last year.
- Ethos went public in January 2026 at a $1.3 billion valuation, roughly half the $2.7 billion mark set in its 2021 SoftBank-led round.
- Through public records requests, the firm obtained consumer complaints to state insurance regulators alleging agent misconduct.
- In one Texas complaint, a consumer alleges an Ethos-platform agent told them to "shut up" before the call escalated into threats.

Wolfpack Research Short Report on XMAX, Inc.
| Metric | Price | Change |
|---|---|---|
| Close (Day Before) | $8.15 | — |
| Low (Report Date) | $7.80 | -4.3% |
| Close (Report Date) | $8.60 | +5.5% |
| Close (End of Week) | $8.39 | +2.9% |
Stock Price Impact: XMAX dipped only 4.3% intraday and actually closed the report date up 5.5%. Shares held most of that gain through the week, ending at $8.39, up 2.9% from the pre-report close. The muted reaction stands in contrast to the scale of the alleged dilution overhang.
About The Company: XMAX, Inc., formerly Nova Lifestyle, is a NASDAQ-listed company with a nominal furniture business that has repositioned around claims of investing in SpaceX and xAI and purchasing AI cloud services. It generated $3.6 million or less in annual revenue as of 2025 and carries a market cap near $518 million.
Key Points from the Report:
- Wolfpack alleges XMAX fabricated purchase orders from Malaysian suppliers, with site visits finding preschools, condos, and apartments instead of businesses.
- At least two of those suppliers share a corporate secretary with XMAX's Malaysian subsidiary and were not disclosed as related parties.
- Six securities purchase agreements disclosed at an average $3.95 per share appear to have raised cash at an actual implied price of $0.91.
- The firm questions $2.3 million in "management fees" paid despite every subscription agreement specifying a 0% fee.
