NEW: We are short Iris Energy $IREN. Our full report is now available on our website, culperresearch.com
2) $IREN was founded in 2018 but now in 2024 promotes itself as an HPC data center play, claiming that "from Day 1, we've built out our facilities" as "multi-decade high-performance data centers." This is a contrived, nonsense pivot reminiscent of COVID-19 era biotech scams.
3) $IREN Co-CEO Daniel Roberts constantly touts $IREN's supposed HPC prowess on paid stock promotion outlets like Proactive and McNallie Money, but behind the scenes has started dumping his own shares alongside his brother and Co-CEO, Will Roberts.

4) Meanwhile, since 2020, $IREN has burned $716 million in cash, and funded this charade by diluting investors to seemingly no end – share count has exploded 12x in the past 4 years. Image
5) $IREN now claims that it has developed "HPC-ready" data centers, but what $IREN is actually building lacks numerous HPC-critical features. The proof is in $IREN's financials: $IREN is spending less than $1M per MW, while true HPC data centers cost $10 to $20M per MW. Image
6) Our analysis of Childress exposes numerous deficiencies. To analogize, $IREN claims that it's set to win the Monaco Grand Prix, but just arrived to the track in a Toyota Prius. Image
6) $IREN implies "Tier 3" standards or better, implying at least one if not two power redundancies (i.e., batteries & diesel generators). Childress, however, has none, and is now stuck - lead times are 1+ years, and we estimate batteries & generators would cost >$1 billion.
8) $IREN also claims to have a "proven" air cooling solution for GPUs in Childress, based on the small cluster of GPUs it has run in BC, where temperatures are 20 to 40 degrees cooler. One expert we spoke with said "they're crazy" to claim that air cooling will work at Childress.
9) $IREN stands alone in its insistence on air cooling: nearly all HPC data centers we reviewed all opted for liquid cooling, especially at higher densities, while NVIDIA's next-generation architecture will require liquid cooling, leaving $IREN in the dust.
Image
Image
10) $IREN claims Childress is an attractive asset due to low power costs, but these costs are low because Childress curtails power and sells power back to the grid. In HPC environments requiring 99.9% uptime, $IREN would need to sign a PPA, likely at a substantially higher cost.
11) $IREN claims its always foreseen the need for HPC, but then decided to build in Childress, Texas, which resembles both a literal and figurative desert. FCC records show Childress County has just a single fiber provider, vs. 20+ by those such as $CORZ in Denton, Texas.
Image
Image
12) $IREN then promotes its undeveloped land and power as being worth "$5 to $12 million per MW" based on a Morgan Stanley research note. But $IREN blatantly misrepresents the note, which referred to fully built infrastructure - not land and power - as being valuable. Image
13) Led on by these claims, $IREN now trades at $7.6 million per MW. Investors cheer on recent M&A offers (CoreWeave for CORZ; RIOT for BITF; CLSK for GRDI) but these came at multiples of $2.3M per MW, $2.6M per MW, and $2.8M per MW, implying 55% downside for $IREN. Image
14/14) Similarly, $IREN shares now trade at 2x public peer levels on multiples of present and fwd. MWs, again implying ~50% downside. $IREN unravels as investors realize the Company's HPC claims are nonsense. We're following the lead set by the Roberts Brothers and selling $IREN. Image

1) We are short Axsome Therapeutics $AXSM. Our full report is now available on our website. culperresearch.com
2) We believe $AXSM's launch of its flagship depression drug, Auvelity, has been aided by undisclosed consignment deals with dodgy mail-order pharmacies that subvert prior authorizations ("PA"), inflating script counts and reported revenues.
3) $AXSM launched Auvelity for MDD in October 2022. Auvelity combines two generics - DXM and Wellbutrin (together just $32/mo) but lists Auvelity at over $1,000/mo. Given its exorbitant pricing amid numerous alternative depression drugs, payors have set up stringent PAs. Image

1) We are short The Bancorp, Inc. $TBBK. $TBBK holds $2B in multifamily bridge loans ("REBLs") and claims the book holds "no substantial risk of losses." We think otherwise. Our full report is now available on our website, culperresearch.com
2) $TBBK has been a sleepy business for a decade plus. But in Q3 2021, $TBBK began originating floating rate REBLs for its own balance sheet. Exposure is now $2.0B, 2.5x $TBBK's equity. Bulls love the decision as $TBBK's multiple has also inflated to 2.5x book value.
Image
Image
3) Despite widely recognized stress in $TBBK's core Class C Sun Belt markets, $TBBK claims "no substantial risk of default and loss." However, using UCCs, liens, deeds, property records, and visits to 21 $TBBK funded properties, we unearthed what we believe are meaningful risks.

1) We are short ACADIA Pharmaceuticals $ACAD. Our full report is now available at culperresearch.com
2) TLDR: Daybue is a total flop. $ACAD misrepresents safety and retention. We think new scripts peaked Aug 2023, revenues will be a fraction of sell-side's $800M+, and knock-on effects are disastrous as $ACAD burns gobs of cash. 3 key insiders have all left in the past 3 months. Image
3) $ACAD launched Daybue in April 2023 for Rett Syndrome, which has no cure. $ACAD says Daybue side effects are mild, but virtually all see diarrhea, while FAERS data suggests ~1 in 10 are hospitalized. In exchange, just 13% see "much improvement" -- a horrific tradeoff.

1) On Monday, Rumble $RUM announced a "partnership" with Barstool Sports, yet still has not issued a Form 8-K, even now, 4+ business days later. This seems to us like an obvious disclosure issue, especially concerning in light of $RUM's reported ongoing SEC investigation.
2) $RUM's PR appears to claim that a) Barstool will provide content, b) $RUM will give up advertising revenues, and c) Barstool will "get access" to Rumble Cloud (note the passive voice). However, $RUM tellingly omits any financial details - we think they're likely horrendous.
3) Moreover, in a Monday interview with @chrispavlovski, Barstool's Portnoy let it slip that $RUM also paid Barstool both cash and stock ("mostly stock"). This tidbit was conveniently omitted from $RUM's press release, while again Pavlovski declined to provide more information.

1) We are short Jin Medical International Ltd $ZJYL, a China Hustle-style charade. Jin sells wheelchairs and parts in China. In 2022, its revenues fell 8% to just $19M. $ZJYL trades at ~45x revenues. At reasonable "peer" levels of 1-6x sales, $ZJYL shares fall 90% or more.
2) $ZJYL went public in March 2023, underwritten by China-focused chop shop, Prime Number Capital. Prime Number is headquartered in a Long Beach home and has already been sued by investors at least twice for alleged roles in other China frauds. Their track record is horrific.

Image
Image
Image
3) In Sept 2023, $ZJYL faced a NASDAQ delisting notice as it fell under the 300 shareholder threshold required for continued listing. On October 24, $ZJYL CEO Erqi Wang filed a Form 144 to sell 545,893 shares. Then $ZJYL fired its auditor, MarcumAsia, and hired DNTW Toronto.

1) We are short XPEL, Inc. $XPEL. Our full report is now available on our website, culperresearch.com
2) We're short $XPEL for two reasons. First, we believe $XPEL has understated its reliance on Tesla by 5-6x. Second, $XPEL faces an undisclosed, existential threat in its long-time supplier entrotech, which is rendering XPEL useless by going direct to OEMs with paint giant PPG.
3) $XPEL claims TSLA PPFs are just 5% of YTD revenues, but our conversations with literally hundreds of PPF installers suggests otherwise... The 143 installers we surveyed across 26 states told us that Teslas are over 30% of their PPF business, on average. Image
