Kerrisdale Capital

Pure Storage, Inc. PSTG

Pure Storage's hyperscaler dream is hype: HDDs dominate at 5-6x TCO advantage, the Meta deal is replicable, and Pure deserves a peer multiple, implying ~55% downside to $35.

CoreWeave, Inc. CRWV

CoreWeave is a debt-fueled, undifferentiated GPU rental stopgap with 71% Microsoft concentration and sub-WACC returns; fair value is $6–13, or 88–95% downside.

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.

D-Wave Quantum Inc QBTS

D-Wave's quantum annealing is a commercial dead end, its 'hybrid' solvers are almost entirely classical, and at 57x 2026E revenue the stock will collapse as reality sets in.

ACM Research, Inc. ACMR

ACMR trades at 1.1x revenue while its 82%-owned Shanghai subsidiary ACMS trades at 6x — a sum-of-parts gap that implies a 10-bagger as China's WFE self-sufficiency drive accelerates.

Red Cat Holdings, Inc. RCAT

Red Cat's $1bn valuation rests on inflating a $23M/year Army drone contract into a $350M sole-source bonanza, with a factory that can't scale and insiders heading for the exits.

Oklo Inc. OKLO

Oklo is a $3bn pre-revenue SPAC nuclear story whose 5x-lowballed fuel costs, unrealistic 2027 NRC timeline, and inexperienced 'Nuclear Bros' management mean shares should collapse as reality intrudes.

Lumen Technologies LUMN

Lumen's 400% AI-fueled rally is an optical illusion: $5bn in PCF deals is construction-contractor funding worth ~$1/share, masking an insolvent, secularly declining telco with $19bn debt.

Riot Platforms, Inc. RIOT

Riot Platforms is a serial-diluting bitcoin miner with $140k+ all-in cost per coin, rising Texas regulatory risk, and a broken model increasingly obviated by low-fee BTC ETFs.

Carvana Co. CVNA

Carvana at $70 is priced as a tech disruptor, but it's 'just a dealership' with CarMax-like unit economics and a levered balance sheet — fair value is $16, -77%.

Carvana Co. CVNA

Carvana is a poorly-run subprime used-car retailer buried under $6.5bn of debt; the recent 165% rally is a loan-sale mirage and the equity is worth zero.

AST SpaceMobile, Inc. ASTS

AST SpaceMobile is a $1.8bn 2021-SPAC promoting a physically implausible direct-to-handset satellite broadband dream; the technology won't work as hyped, timelines keep slipping, and SpaceX/Apple competition eliminates any lead.

Digital World Acquisition Corp DWAC

DWAC's $8bn pro-forma SPAC merger with Trump's TMTG will never close because the SEC is actively investigating it and can kill the deal via a stop order — fair value is the $10 trust cash (-80%).

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.

Acutus Medical Inc. AFIB

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.

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.

The St. Joe Company JOE

St. Joe's Florida Panhandle land bank is worth a fraction of what bulls claim; absent the promised population boom, the stock is materially overvalued and a short.

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.
