Andrew Left convicted of fraud as 5 new short reports land this week
Weekly Wrap Up: Sunday, June 7, 2026
If you follow short selling, you didn't talk about much else this week. On June 1 a federal jury in Los Angeles convicted Andrew Left, the founder of Citron Research, on thirteen of seventeen securities fraud counts, and the verdict sent a real jolt through the people who do this work for a living. The thing worth understanding is what the case actually punished. Prosecutors never argued that Citron's research was false. They went after the gap between what Left said publicly and how he traded, telling followers he was short while he was already covering. That distinction is why so many investigators spent the week rethinking how they disclose live positions rather than packing up entirely. We dug into what the decision means for the field in a new piece on the site. And the reports kept coming. Five new campaigns landed despite the noise, hitting names from a Swedish semiconductor highflyer to an Italian tire maker with a Russia problem, with stocks moving hard in both directions. Here is everything that published.
- Ningi Research targeted Sivers Semiconductors (SIVE.ST), alleging fabricated revenue growth and improperly booked US CHIPS Act grants. Stock closed the week up 14.29%.
- Fugazi Research targeted Astrotech (ASTC), alleging a serial capital-consumption vehicle with a substanceless lunar pivot. Stock closed the week down 5.37%.
- Grizzly Research targeted Pirelli (PIRC.MI), alleging concealed Russian operations tied to sanctioned defense conglomerate Rostec. Stock closed the week down 2.28%.
- Shortfinder flagged U.S. Gold Corp (USAU) in its systematic short rankings. Stock closed the week down 10.71%.
- Pelican Way Research targeted CitroTech (CITR), alleging a commercially failed fire retardant technology run by serial promoters. Stock closed the week down 2.85%.

A close read of what the Andrew Left conviction actually decided, and what it did not. The jury convicted on a scalping theory rather than a short-and-distort theory, meaning prosecutors never alleged Citron's research was false. We break down what changes immediately for investigators and what stays unresolved until the government has to defend its theory on appeal.
New Activist Reports
Ningi Research Short Report on Sivers Semiconductors
| Metric | Price | Change |
|---|---|---|
| Close (Day Before) | $68.95 | — |
| Low (Report Date) | $58.40 | -15.30% |
| Close (Report Date) | $60.85 | -11.75% |
| Close (End of Week) | $78.80 | +14.29% |
Stock Price Impact
Ningi's report landed on June 1 and Sivers dropped fast, falling as much as 15.3% intraday to a low of SEK 58.40 from the prior close of SEK 68.95. The stock settled the session down 11.75% at SEK 60.85. What happened next was the surprise. Rather than extending losses, Sivers reversed sharply and finished the week at SEK 78.80, up 14.29% from where it stood before the report. The rebound is striking given the stock's 1,800%-plus rally this year, and it suggests momentum buyers stepped in faster than the allegations could land. Short reports on heavily owned momentum names often see this kind of violent two-way action, where the initial drop gives way to a squeeze before the thesis has time to play out.
About The Company
Sivers Semiconductors is a Swedish company that makes laser diode components for photonics and wireless applications, manufactured from a 22,000-square-foot prototype foundry in Glasgow. It reported roughly $32 million in 2025 revenue while carrying a market value near $2.2 billion during the report period, a gap that reflects investor enthusiasm for any name linked to AI data center and defense supply chains. The company sits several steps removed from those end customers and has pursued development agreements with partners including Ayar Labs, ALL.SPACE, and POET Technologies. It also received funding under the US CHIPS Act. Sivers holds six granted patents, a fraction of the thousands held by larger optical peers like Lumentum and Coherent, and announced plans this spring for a US dual listing.
Key Points from the Report
- Ningi alleges at least SEK 97M, roughly 31% of 2025 revenue, is dubious, including SEK 55.2M of US CHIPS Act grants booked as commercial NRE revenue in alleged violation of IAS 20 and IFRS 15.
- The report says SEK 42.2M in Ayar Labs "product sales" was recognized despite no US import records of any shipment from Sivers.
- According to Ningi, board director Erik Fällström's Achilles Capital liquidated its entire 29 million share stake for at least SEK 461M while Fällström publicly called the stock "significantly undervalued."
- Ningi reports that every hyped customer relationship, from a Fortune 100 client to ALL.SPACE, ended without a volume order, and a veteran NVIDIA engineer said Sivers cannot match peers on reliable high-volume delivery.

Fugazi Research Short Report on Astrotech Corporation
| Metric | Price | Change |
|---|---|---|
| Close (Day Before) | $35.40 | — |
| Low (Report Date) | $28.29 | -20.08% |
| Close (Report Date) | $45.50 | +28.53% |
| Close (End of Week) | $33.50 | -5.37% |
Stock Price Impact
Astrotech gave shorts a wild ride. After Fugazi published on June 2, the stock plunged as much as 20.08% intraday to $28.29 from its prior close of $35.40, then staged a violent reversal to close the session up 28.53% at $45.50. The whipsaw is typical of thinly traded microcaps where a short report collides with speculative buying, in this case around the company's freshly announced lunar initiative. By the end of the week the enthusiasm had faded and Astrotech closed at $33.50, down 5.37% from its pre-report level. The net move was modest, but the path there underscores how unpredictable these campaigns can be when the target is a low-float name with an active retail following.
About The Company
Astrotech Corporation traces its roots to 1984, when it was incorporated as SPACEHAB, a NASA contractor. Since 2018 it has repositioned itself five times across aerospace, industrial technology, COVID breath analysis, airport security, and defense. The company operates six wholly owned subsidiaries, but nearly all product revenue comes from a single one through the Tracer 1000, a mass-spectrometry-based explosives trace detector. Annualized revenue runs around $1.05 million. Astrotech is led by Thomas Boone Pickens III, who holds the CEO, CTO, Chairman, and Principal Financial Officer titles at the same time. In late May the board approved a new lunar resource and infrastructure initiative, the strategic pivot that frames Fugazi's report.
Key Points from the Report
- Fugazi alleges Astrotech has destroyed roughly 95 cents of every dollar invested, carrying a $262M accumulated deficit against $274M in total paid-in capital.
- The report says the company generated $787,000 in revenue over nine months against $11.15M in operating expenses, leaving about four months of cash runway as of March 31, 2026.
- According to Fugazi, CEO Pickens holds four executive roles with no independent oversight, and the company paid his son-in-law $211,000, roughly 30% of revenue, in consulting fees.
- The May 27 lunar pivot, the company's sixth strategic narrative, disclosed no customers, contracts, or funded missions and described itself as in an early evaluation phase.

Grizzly Research Short Report on Pirelli & C. S.p.A.
| Metric | Price | Change |
|---|---|---|
| Close (Day Before) | $6.14 | — |
| Low (Report Date) | $5.31 | -13.52% |
| Close (Report Date) | $6.05 | -1.47% |
| Close (End of Week) | $6.00 | -2.28% |
Stock Price Impact
Pirelli shares dropped sharply on the open after Grizzly published on June 4, falling as much as 13.52% intraday to €5.31 from the prior close of €6.14. The selling did not hold. The stock recovered most of the loss to finish the session down just 1.47% at €6.05, and ended the week at €6.00, off 2.28% from its pre-report level. For a large, liquid, F1-branded name on the Milan exchange, the muted close is not unusual. Sanctions and disclosure allegations tend to be slow-burning catalysts that play out through regulators and headlines over months rather than in a single session, and the market appeared to treat the report as a risk to monitor rather than an immediate repricing event.
About The Company
Pirelli is an Italian tire manufacturer listed in Milan and best known as Formula 1's exclusive tire supplier. It is also the only remaining Western tire maker with active production inside Russia, operating factories in Kirov and Voronezh through its Pirelli Tyre Russia subsidiary. A research institute fully owned by sanctioned Russian state conglomerate Rostec holds a 25.005% stake in that subsidiary. Pirelli reports Russian results inside a combined "Russia and Middle East, Africa and India" segment that accounts for roughly 6% of revenue, and has invested about €470 million in the country while taking only around €40 million in write-downs. That Russian footprint is the focus of Grizzly's report.
Key Points from the Report
- Grizzly alleges a Rostec-owned research institute holds a 25.005% stake in Pirelli's Russian subsidiary and is never named in any Pirelli annual report.
- The report says the Kirov factory produced tires for Russian military platforms including the RS-24 Yars nuclear-warhead launcher, with an employee confirming one tire is used "exclusively by the Strategic Rocket Forces."
- According to Grizzly, Russian statutory filings imply Russia contributes about 10% of net profit, well above the roughly 6% revenue share Pirelli's segment disclosure suggests.
- Undercover calls reportedly revealed active military-linked sales and recent hiring of Russian invasion veterans, alongside a tire center listed in Russian-occupied Donetsk that Grizzly characterizes as an EU sanctions violation.

| Metric | Price | Change |
|---|---|---|
| Close (Day Before) | $6.67 | — |
| Low (Report Date) | $6.00 | -10.04% |
| Close (Report Date) | $6.48 | -2.85% |
| Close (End of Week) | $6.48 | -2.85% |
Stock Price Impact
Pelican Way's report on CitroTech published June 5, the final trading day of the week, so the market's reaction is still early. The stock fell as much as 10.04% intraday to $6.00 from its prior close of $6.67 before recovering to close at $6.48, down 2.85% on the day. Because the report landed on a Friday, the end-of-week figure mirrors the report-date close at $6.48. The partial recovery from the intraday low suggests the market is still digesting Pelican Way's allegations about a roughly $150 million company built on a commercially questionable product. How the thesis plays out will be clearer once a full week of trading follows publication.
About The Company
CitroTech Inc. is a specialty chemical company that sells fire retardant products based on Tri-Potassium Citrate, a commodity food-grade potassium salt more commonly used in sports drinks and food processing. The company reported roughly $2.4 million in FY25 revenue against a market capitalization near $150 million, implying a valuation around 57.5 times sales. CitroTech describes itself as focused on environmentally sustainable fire inhibitor products and says it holds a portfolio of 37 issued US patents. Notably, its own FY25 10-K discloses that it does not have major sales from recurring customers. The company trades on NYSE American under the ticker CITR.
Key Points from the Report
- Pelican Way alleges insiders extracted roughly $10M in FY25 stock awards, climbing past $15M including awards to Craig Huff, against just $2.4M in revenue.
- The report cites a 2024 peer-reviewed University of Göttingen study finding TPC loses fire-retardant effectiveness after water exposure, contradicting marketing claims of protection lasting "weeks to months."
- According to Pelican Way, five prior entities tried and failed with the same underlying TPC chemistry, which traces to an Indonesian inventor in the 1990s.
- The report flags former CTO Steve Conboy's $7.5M advisory royalty clause and ties nearly every CitroTech capital raise to Univest Securities, a placement agent previously censured and fined by FINRA.
