SEQH Capital Research | November 21, 2025 Call

OPERATIONAL UPDATES: THREE FACILITIES IN PRODUCTION

Silicon-28 Plant (ASP Technology)

Status: Commercial production, customer sample validation complete
Progress: Plant modifications “nearly complete”; September customer site visit resolved technical specifications
Timeline: Q1 2026 first large contract delivery; all 2026 orders expected to be fulfilled
Market: Quantum computing and semiconductor applications

Ytterbium-176 Plant (Quantum Enrichment Technology)

Status: Transitioned to commercial production; lutetium-177 precursor for cancer therapeutics
Progress: Commercial sample shipped for independent analysis
Timeline: First commercial deliveries H1 2026
Expansion: Four new QE facilities in procurement; regulatory approvals secured for all four
2026 Target: Gadolinium-160, nickel-64, zinc-67/68, barium isotopes

Carbon-14/Carbon-12 Plant

Status: Feedstock issues resolved; carbon-12 pivoted to commercial opportunity
Breakthrough: First isotope enrichment revenue expected December 2025 (carbon-12 to global gas company)
Carbon-14: First commercial shipments H1 2026 (pending January feedstock delivery)
Sample Result: Commercial carbon-12 at 99.99% purity received positive customer feedback

STRATEGIC INITIATIVES

Renergen Acquisition (South African LNG/Helium Producer)

Status: 99.8% shareholder approval (July 2025); final regulatory approval imminent
Phase 1C Target: Operational de-risking by Q1 2026
Strategic Value: Vertical integration into helium supply for semiconductor industry; $750M committed debt funding
2030 Target: Combined entity targeting $300M+ EBITDA

Quantum Leap Energy IPO (Q4 2025)

S-1 Filing: Confidentially submitted November 12, 2025
Funding: $64.3M raised via convertible notes (Nov 2025); pro forma cash $81.6M
Mission: Stabilize nuclear fuel supply chain; key products: lithium-6/7, LEU Plus (5-10% enrichment), HALEU (10-20%), KUBE cesium-137 waste treatment
Geographic Expansion: Iceland supercenter, U.S./U.K. facilities under construction; MOU with Fermi America for Amarillo HyperGrid

Skyline Builders (Critical Materials Platform)

Assets Acquired: 20% stake in Asian critical materials company (December disclosure TBD); Supercritical Technologies (seawater uranium extraction)
Capital: $41.7M raised into Skyline for acquisitions
Strategic Rationale: Vertical integration from feedstock extraction to end-product delivery

PET Labs Radiopharmaceutical Expansion

YTD Performance: Revenue up 24% to $3.6M; Q3 revenue $1.3M (+18% YoY)
New Equipment: Cyclotron, PET-CT, SPECT pharmacy commissioned and operational
U.S. Expansion: Acquired East Coast Nuclear (Florida), first radiopharmacy outside South Africa
Pipeline: Non-binding term sheet for second U.S. acquisition; multiple acquisition discussions underway

2026 CATALYSTS & FORWARD GUIDANCE

Revenue Opportunity: $50-$70M from silicon-28 and ytterbium-176 alone (2026-2027); management declined to update detailed guidance pending “corporate events”

KEY MANAGEMENT COMMENTARY

CEO Robert Ainscow on Silicon-28 Delays:
“First production runs of nuclear engineering and isotope enrichment are extremely complex physical and chemical procedures. September customer visit really changed the dynamic of the customer-supplier relationship.”

CFO Heather Keesling on Operating Expense Growth:
“We expect cash burn from operations and continued growth of planned plants and global radiopharmaceutical operations to increase as we bring more isotope enrichment plants online.”

QLE CEO Dr. Rhino Pretorius on Supply Chain Strategy:
“Lithium-7 for pH control in 80% of nuclear reactors; lithium-6 for fusion; only one commercial producer exists globally, sitting outside Western secure supply chain.”

BULL CASE | BEAR CASE

BULL:

Three operational enrichment facilities; technology de-risked
Multiple near-term revenue catalysts (carbon-12 Dec, silicon-28/ytterbium 2026)
$314M cash position (post-October raise) provides runway
Unique vertical integration across isotopes, helium, energy, uranium
Government support for critical materials supply chain
Strong customer validation and new contract wins

BEAR:

Continued delays on silicon-28, carbon-14 shipments
Operating expenses up 84% YoY; further increases expected
Net losses widening to ($96.5M) YTD 2025
Complex multi-front execution (Renergen, QLE IPO, facility construction)
Lack of updated detailed guidance; modeling uncertainty
No isotope enrichment revenue yet; relies on 2026 ramp

VALUATION & KEY METRICS

Market Cap: ~$1.4B (at $12.25/share, 114M shares post-dilution)
Enterprise Value: ~$1.3B (net cash position)
Price-to-Sales: N/A (minimal revenue base)
Cash Burn Rate: $19.4M YTD 2025 (up 50% YoY); expected to accelerate in 2026
Cash Runway: ~18+ months at current burn rate (longer with improved isotope revenue)

Valuation Drivers: Execution on commercial ramp, Renergen integration success, QLE IPO valuation, radiopharmacy EBITDA profile, government contract wins

INVESTMENT THESIS

ASP Isotopes stands at a critical inflection point from R&D-stage to commercial production. With three operational enrichment facilities, validated technology through customer samples, strengthened balance sheet ($314M cash), and clear near-term catalysts (carbon-12 December, silicon-28 2026), the company is positioned for transformative 2026. However, significant execution risk remains across simultaneous initiatives (Renergen integration, QLE IPO, multi-country facility construction, radiopharmacy expansion) while cash burn accelerates. December carbon-12 revenue recognition and Q1 2026 Renergen closure will be critical proof points for investment thesis validation.
