Muddy Waters

SoFi Technologies, Inc. SOFI

Grizzly Research

Ceres Power Holdings plc CWR

Ceres Power's decade of hyped SOFC partnerships (Bosch, Nissan, Honda, Doosan) has produced only negligible royalties; the market-cap surge from partnership announcements will fade as revenue reality emerges.

Industry meta-study: 24 firms that sued short sellers (2018-2025)

Firms that sue activist short sellers underperform the S&P 500 by 72% long-term — the lawsuit is a bluffing signal that confirms, rather than refutes, the short thesis.

Scorpion Capital

Soleno Therapeutics SLNO

Scorpion shorts Soleno (SLNO), arguing VYKAT XR — a $500K/year repackaged 50-year-old generic — is causing pediatric heart-failure hospitalizations and was approved on sham trial data; the launch will collapse.

N4 V2

Aug 01, 2025

Kerrisdale Capital

Aurora Innovation, Inc. AUR

Aurora's autonomous trucking vision is a dead end: tech can only enable hub-and-spoke freight, drayage kills the economics, and the real TAM is smaller than the company's $13bn market cap.

N4 V3

Muddy Waters

e.l.f. Beauty, Inc. ELF

ELF's imports collapsed while inventory and revenue kept soaring; reconciling the two suggests $138-188mm of overstated sales and a likely fraud.

N5 V3

TI's rigid $5bn/year capex ramp is building ~50% excess capacity and has collapsed FCF per share 75%; flex capex to demand and commit to $9.00+ per share by 2026.

Muddy Waters

CPI Property Group CPIPG

CPIPG's 2023 results show undisclosed related-party transfers to controlling shareholder Vitek, aggressive fair-value inflation, and an unreconciled 92% equity collapse at GSG Berlin — management must answer on the call.

Sunrun RUN

Sunrun's Subscriber metric is fabricated — inflated ~20% above EIA filings — letting it overclaim ~$205M in IRS tax credits and prop up a fictitious valuation; Muddy Waters remains short.

N4 V2

Ancora

Ritchie Bros. Auctioneers RBA

Back the amended RBA-IAA merger: $350-900M of synergies, a Starboard/Ancora-refreshed board, and Luxor's anti-deal case is flawed — RBA should re-rate from $62 to ~$130.

Hannon Armstrong Sustainable Infrastructure Capital HASI

HASI is a short: its GAAP and non-GAAP 'Distributable Earnings' are inflated by three non-cash accounting tricks and roundtripped SunStrong loans, masking a cash-losing, capital-raise-dependent business.

N4 V2

Dec 01, 2021

Kerrisdale Capital

Astra Space, Inc. ASTR

Astra is a SPAC-bubble rocket company with no revenue, an undersized non-reusable vehicle, and fantastical 300-launch-a-year forecasts; shares should tumble back to the ground.

N4 V1

Feb 15, 2019

Citron Research

Inogen INGN

Inogen's growth is built on a reseller network that lies to elderly customers about Medicare coverage to force cash sales — competition and oversight will collapse margins to a $46 stock.

TAL inflated Firstleap's acquired deferred revenue by 90-175%, pumping $21-29M of fake profit through FY2017 via an above-the-line accounting lever obscured by an overlooked small acquisition.

Greenlight Capital

Assured Guaranty AGO

Assured Guaranty is a melting-ice-cube bond insurer aggressively returning capital it hasn't earned; Puerto Rico losses alone (2-4x reserves) will force a capital raise or strip the AA rating it needs to write new business.

Muddy Waters

IQE plc IQE

Muddy Waters is short IQE: the compound-semi maker inflated 2015/2016 net income by 58.5%/25.4% via transactions with its Cardiff University JV — an alter ego, not an arm's-length partner.

Alpine Electronics 6816

Alps Electric is buying out 40%-owned Alpine Electronics via a biased share-exchange at too low a price; minority holders should reject it and demand a tender offer near 2,400 yen.

Asanko Gold Inc. AKG

Muddy Waters is short AKG: flawed geology, a collapsing Nkran pit, and a 2018 liquidity crunch make the Ghana gold miner highly likely to end up a zero.

Greenlight Capital

Core Laboratories CLB

Core Lab trades at 35x 2018e P/E — double its oilfield-service peers — on a false secular-growth narrative; mid-cycle earnings imply $62 fair value and ~45% downside.

Sotheby's Board has presided over a 42% EPS collapse despite global wealth tailwinds; electing Third Point's three nominees can restore owner perspective and more than double pro-forma EPS.

N4 V3

Jan 13, 2014

Elliott Management

Juniper Networks JNPR

Juniper has badly underperformed peers for a decade; a $200M cost cut, a $3.5B buyback with dividend, and a security/switching review can drive shares to $35–$40 (57–77% upside).

Oct 24, 2013

Muddy Waters

NQ Mobile Inc. NQ

NQ Mobile is a 'China Fraud 2.0': 72%+ of China revenue is fictitious, real market share is 1.4% not 55%, and the $127.9M cash balance is likely forged — target price under $1.

Starboard Value

Tessera Technologies Inc. TSRA

Tessera has squandered $517M on the failing Digital Optics business while its core patent-licensing franchise shrinks; Starboard's six-director slate and IP-focused plan can unlock best-in-class 60-70% EBITDA margins.

Greenlight Capital

Green Mountain Coffee Roasters GMCR

GMCR's $9 EPS bull case ignores a smaller TAM, falling K-cup attachment rates, a September 2012 patent cliff, and accounting shenanigans at fulfillment agent MBlock — realistic EPS is ~$3.50.

Hong Kong Dollar / Hong Kong Monetary Authority (HKMA) HKD

Hong Kong's USD peg forces the booming HKD to import US ultra-accommodative monetary policy, fueling inflation and property bubbles; a 30% revaluation to 6:1 offers ~44x upside via cheap call options.
