Land & Buildings 2025-06-17

National Healthcare Corporation NHC

NHC's below-market 1991 lease with NHI expires 2026; renegotiation will cut NHC EBITDA 19-38% — L&B is short NHC.

N3 V2 C1
Trian Partners 2025-01-08

Solventum Corporation SOLV

Solventum's post-spin performance collapse is nearly worst-in-class; restoring 3M-era 3-4% growth and 26% margins plus simplifying the portfolio can double shares to $140 by 2027.

Starboard Value 2024-10-01

Pfizer Inc. PFE

Pfizer destroyed $20-60bn of value since 2019 despite a $40bn COVID windfall; Starboard wants the board to hold Bourla accountable for peer-median R&D/M&A returns.

N5 V4 C4
Starboard Value 2024-10-01

Pfizer Inc. PFE

Pfizer squandered its $40bn COVID windfall on overpriced M&A while delivering almost none of the 15 promised blockbusters; the Board must hold management accountable.

Muddy Waters 2024-07-23

Eurofins Scientific SE ERF

Eurofins' €556m 'excess cash' earned just 1.42% vs banks' quoted ~2.88%, echoing the NMC Health fraud tell; only radical disclosure on cash, entities, and Dr. Martin's real estate can clear it.

N4 V2 C2
Muddy Waters 2024-07-03

Eurofins Scientific SE ERF

Eurofins' 800+ immaterial subsidiaries and 18 auditors enable sham sales and cash double-counting; new evidence, including a factoring denial contradicted by a former BU head, argues the financials cannot be trusted.

N4 V2 C2
Muddy Waters 2024-06-24

Eurofins Scientific SE ERF

Muddy Waters is short Eurofins: controlling shareholder Dr. Gilles Martin has siphoned capital via above-market real-estate leasebacks for 20 years, and the financials appear engineered to overstate revenue, profits, and cash.

N4 V2 C2
Ancora 2024-02-01

Elanco Animal Health ELAN

Elanco has destroyed billions under CEO Simmons and an insular classified board; replacing four directors at the 2024 AGM installs accountability and unlocks the animal-health turnaround.

N4 V4 C4
Citron Research 2023-11-06

Apellis Pharmaceuticals APLS

Citron shorts Apellis, arguing its new Geographic Atrophy drug Syfovre faces an imminent FDA warning as AAO ophthalmologists reject it 83%-17% and vasculitis cases mount.

N4 V2 C2
Starboard Value 2023-10-01

Fortrea Holdings Inc. FTRE

Fortrea, LabCorp's spun-out CRO, earns 9% EBITDA margins versus 18% peers; CEO Tom Pike's IQVIA playbook implies $47-$72 per share, 60-144% upside at normalized margins.

N4 V3 C3
Muddy Waters 2023-06-07

Chinook Therapeutics KDNY

Chinook manipulated 2021-2022 revenues via its Chinese JV SanReno; strip out the accounting tricks and reported revenue collapses by 95% and 68% respectively, reinforcing our short.

N4 V2 C1
Muddy Waters 2023-05-16

Chinook Therapeutics Inc KDNY

Muddy Waters is short Chinook (KDNY): lead drug atrasentan is inefficacious, harmful, and blocked by sparsentan's IgAN orphan-drug exclusivity — FDA approval is highly unlikely.

Acutus Medical Inc. AFIB

N3 V3 C3
Muddy Waters 2020-11-11

MultiPlan Corp MPLN

N4 V2 C2
Muddy Waters 2020-09-22

Nano-X Imaging Ltd. NNOX

Nanox's $1.3B medical-imaging story is a stock promotion: the ARC device appears to be a prop, distribution partnerships are shams, and a convicted felon engineered the IPO.

N5 V2 C1
Kerrisdale Capital 2020-09-01

AtriCure, Inc. ATRC

AtriCure's 7.5x revenue valuation assumes stand-alone Convergent succeeds, but electrophysiologists won't refer, and PFA plus real-time mapping will obsolete surgical ablation.

N4 V3 C2
Muddy Waters 2020-06-02

eHealth, Inc. EHTH

EHTH books Medicare Advantage revenue today that takes nine to twenty years to collect, masking a cash-incinerating, high-churn business reminiscent of Enron-style accounting.

N4 V2 C2
Elliott Management 2020-05-12

Alexion Pharmaceuticals, Inc. ALXN

Alexion's stand-alone strategy has failed — serial M&A missteps and a deep valuation discount mean the Board must pursue a sale now to unlock 40-50% upside for shareholders.

N5 V3 C3
Muddy Waters 2020-04-08

eHealth Inc. EHTH

eHealth books three years of Medicare Advantage commissions upfront while true churn has spiked to 47%; corrected, every MA enrollee loses $135-$402 — a cash-incinerating stock promotion.

N5 V2 C2
Muddy Waters 2020-02-10

NMC Health plc NMC

Newly disclosed NMC share pledges corroborate Muddy Waters' hidden-debt thesis: likely Enron-style off-balance-sheet financing or subsidies from undisclosed Shetty-family related parties inflating margins.

N4 V1 C1
Muddy Waters 2019-12-17

NMC Health plc NMC.LN

NMC Health's UAE hospital empire is built on inflated capex, overstated cash, hidden reverse factoring and related-party self-dealing — Muddy Waters is short and sees deep, possibly fraudulent rot.

N5 V1 C1
Muddy Waters 2019-11-07

PeptiDream, Inc. 4587 JP

PeptiDream's 19 pharma 'partnerships' are largely dormant and 13 years of R&D have produced zero Phase 2 drugs — analyst 2027 revenue forecasts will miss by over 60%.

N4 V2 C2
Kerrisdale Capital 2019-07-01

CareDx, Inc. CDNA

CareDx is a $1.7bn story built on AllSure, a cfDNA kidney-rejection test that misses 40% of rejections and faces 70% annual patient attrition, competition and Medicare reset — ~70% downside.

Starboard Value 2019-03-18

Bristol-Myers Squibb BMY

BMY is overpaying ~$30B for Celgene's risky pipeline, betting on 10 blockbusters in 8 years vs 3 in 15; shareholders should vote against and unlock 900bps of standalone margin upside.

N5 V3 C3
Starboard Value 2019-03-01

Bristol-Myers Squibb BMY

BMY's $91B Celgene deal bets the company on a REVLIMID patent cliff and pipeline requiring 10 blockbusters in 8 years — shareholders should vote no and pursue a standalone Amgen-style transformation.

N5 V3 C3
Starboard Value 2019-02-28

Bristol-Myers Squibb Company BMY

Bristol-Myers' $91bn Celgene acquisition buys pharma's largest patent cliff; Starboard urges shareholders to vote it down and replace directors to pursue a standalone plan or sale.

N4 V3 C3
Starboard Value 2019-02-28

Bristol-Myers Squibb Company BMY

Starboard urges BMY shareholders to reject the $91B Celgene acquisition — it imports a massive REVLIMID patent cliff and was rushed through without exploring standalone turnaround or a sale of Bristol-Myers.

Muddy Waters 2019-02-25

Inogen INGN

INGN's growth narrative rests on an inflated $3-4B TAM that Medicare data contradicts; under a realistic 1.3M-user market, peak unit sales arrive this year or next.

N4 V1 C1
Starboard Value 2019-02-22

Magellan Health, Inc. MGLN

Magellan destroyed $700M of value through failed acquisitions and three 2018 guidance cuts; Starboard's six-director slate will overhaul the board and run a parallel sale process at peer multiples.

N4 V2 C2
Citron Research 2019-02-15

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.

N4 V2 C2
Muddy Waters 2019-02-08

Inogen, Inc. INGN

Inogen's growth story rests on a fabricated TAM sourced from a plagiarism-riddled WinterGreen report; real market is shrinking, peak sales arrive 2019-2020, target $46 (-67%).

N5 V2 C2
Elliott Management 2018-05-14

athenahealth, Inc. ATHN

Elliott's $160 cash offer for athenahealth is being stonewalled by a disengaged board; immediate engagement on a take-private transaction is the value-maximizing path for shareholders.

N3 V2 C1
Elliott Management 2018-05-07

athenahealth, Inc. ATHN

Elliott offers $160/share cash for athenahealth — a 27% premium valuing the company at ~$6.9bn — arguing chronic execution failures make going private the only path to realizing its HCIT potential.

N4 V2 C1
Kerrisdale Capital 2017-11-01

Adamas Pharmaceuticals, Inc. ADMS

Kerrisdale is long ADMS: Gocovri, the only FDA-approved drug for levodopa-induced dyskinesia, plus an MS and Vimpat XR pipeline, is worth over $100/share versus ~$25 today.

N4 V3 C2
Muddy Waters 2017-06-29

Prothena Corp PLC PRTA

Short PRTA: publicly-available NEOD001 data does not show efficacy — organ responses are likely driven by prior PCD chemo, not the drug, and $1.5B peak sales are unrealistic.

N4 V2 C2
Starboard Value 2016-09-12

Perrigo Company plc PRGO

Perrigo lost half its value after rejecting Mylan's $205 bid; divesting Rx and Tysabri royalty, fixing BCH margins, and restoring credibility can re-rate the stock to consumer-staples peers.

N4 V3 C3
Muddy Waters 2016-08-29

St. Jude Medical STJ

STJ's rebuttal to Muddy Waters' cybersecurity short report is 80% fluff and 20% substance, with admissions and deception cues that confirm its cardiac devices remain unsafe and need recall.

N4 V1 C1
Muddy Waters 2016-08-25

St. Jude Medical, Inc. STJ

St. Jude's $23B cardiac-device franchise rests on a Merlin ecosystem so insecure that hackers can crash pacemakers from 50 feet — a recall and two-year remediation imply 50%+ downside and likely covenant breach.

Valeant Pharmaceuticals International, Inc. VRX

Joseph C. Papa appointed Chairman and CEO of Valeant

N1 V2 C1
Starboard Value 2016-04-08

Depomed, Inc. DEPO

N5 V3 C3
Citron Research 2015-10-21

Valeant Pharmaceuticals VRX

Philidor and R&O Pharmacy are the same entity — evidence of phantom accounts to book revenue

N5 V3 C3
Pershing Square 2015-05-04

Valeant Pharmaceuticals International VRX

Platform companies are undervalued because P/E ignores value from future acquisitions

N5 V4 C4
Pershing Square 2015-05-01

Valeant Pharmaceuticals International VRX

Traditional P/E ignores Valeant's 'Platform Value' from disciplined M&A capital allocation

N4 V3 C3
Greenlight Capital 2014-05-05

athenahealth ATHN

athenahealth is the poster child of the cloud 'bubble basket' — strip Morgan Stanley's fantasy margin and revenue-per-doctor assumptions and the stock falls 80%+ toward a $50 adjusted DCF.

Glenview 2013-08-01

Health Management Associates HMA

HMA's incumbent board destroyed 25% of independent value before rushing a sale to Community Health Systems; Glenview's Fresh Alternative board protects the deal and recovers upside.

N4 V2 C2
Glenview 2013-07-01

Health Management Associates HMA

HMA's insular 17-year-tenure board drove a Lost Decade of <1% TSR; replace all directors with Glenview's blue-chip slate to fix governance, compensation, and capital allocation.
