INVESTOR DILIGENCE · MODULAR FACTORY #1

Six things an investor needs satisfied

Every institution asks the same six questions, and says no at the first one that fails. Answered here against one real deployment: Modular Factory #1, on a 19-acre parcel leased from the York County Solid Waste and Refuse Authority, under an executed 30-year Circular Supply Agreement (CSA).

01 · PERFORMANCE

Technology risk is designed to resolve into four covered pieces

Modular Factory #1 is contracted at 100 TPD across four units, roughly 25 TPD each. Nobody is asked to take an undifferentiated bet on it. The risk is broken apart, and the program below gives each piece an owner who is paid to carry it. None of these instruments is in place today. Each is planned for after the Cornerstone round closes, at the point in the build where it can be priced sensibly, and each is funded from the Use of Proceeds.

01
Proven equipment, to be delivered under vendor warranty. Almost everything in the module is established, commercially available equipment with reference installations. Warranties attach on purchase; no equipment has been purchased.
02
Integration to be wrapped by the Master Authorized Systems Integrator (MASI), with liquidated damages. The MASI will be accountable for making the pieces work together at York, and will pay if they do not. The MASI agreement is to be executed after capitalization; no MASI wrap is in place.
03
Equipment shortfall to be transferred to a rated carrier. The equipment is recipe controlled, so its operating envelope is definable and, in management's judgment, insurable under a performance policy. No performance policy has been bound; placement depends on carrier appetite and pricing at the time.
04
Receivables to be insured against non-payment. Intended to be placed through Aon plc, the Company's broker of record, so that a Feedstock Provider failure does not become the Company's loss. No receivables policy has been bound.

02 · REVENUE

Three streams, three separate counterparties

Module 1 carries 100 TPD, roughly 36,500 tons of Gross Input Tonnage a year at 365 operating days. That tonnage earns in three independent ways, each under its own agreement.

ONE · CSA
Beneficiation Fee (TMC Fee)
$75 per ton at York, paid by the Feedstock Provider, escalating 2.5% a year.
TWO · CMOA
Circular Materials sales
Paid by industrial offtakers, across 116 materials in six families.
THREE · CEAA
Environmental attributes
Paid by attribute and registry buyers, on the same tonnage.
The cost side is one line.
Carbotura pays the Circular Royalty™ back to the Feedstock Provider at $90 per ton, beginning 13 months after the first Beneficiation Fee payment. That royalty is the raw-material cost of the business and the only feedstock cost there is.
Roughly 100% converted.
About 90% of output is sold; the remaining 10% is used internally to self-power the plant.
SINGLE MASS-BASIS RULE  ·  THE SAME TONS COUNTED ONCE IN EACH DIMENSION. THE THREE STREAMS ARE NEVER SUMMED, AND THE FEE AND THE ROYALTY ARE NEVER NETTED.

03 · CAPITAL

$75M builds York module 1

Capacity at York is reached by replicating one manufactured module, not by designing a larger facility each time. That is what makes the cost knowable in advance.

$75M
Module 1, including the shared infrastructure and building the rest of the site inherits
$55M
Each additional module, against the same production specification
$240M
York's contracted 400 TPD in total, as four identical 100 TPD modules
12–24 mo
Permit issuance to commercial operation
01
$75M of the $100M Cornerstone Round goes in as hard equity. Into Carbotura York, LLC, and it builds module 1 at 100 TPD.
02
Modules 2 through 4 are intended to carry debt. Lenders are intended to advance against a qualified production specification, to be insured once a performance policy is bound (none is today), and against measured performance from module 1, rather than against a promise.

04 · TEAM

Carbotura is the OEM. Integrators deploy.

The company that authors a specification and the companies that install it are deliberately different parties, each accountable for what it is good at.

01
Carbotura owns the specification. As OEM, Carbotura authors the ACM module production specification and governs how modules are manufactured.
02
Authorized Systems Integrators deploy. The Master Authorized Systems Integrator (MASI) is the single accountable party for factory acceptance, site acceptance, integration testing and the full-line warranty.
03
Multiple ASIs, not one contractor. No single integrator is a chokepoint across York or the build programme behind it.
04
Nothing is licensed in. Carbotura owns the process architecture and the marks. Equipment components are bought from established vendors, as any manufacturer buys parts.
SAME SPECIFICATION, SAME TOLERANCE, EVERY MODULE  ·  EXECUTION RISK IS A MANUFACTURING QUESTION, NOT A CONSTRUCTION ONE

05 · VALUE

$3.6B GRV, certified conservatively

York's contracted 400 TPD is booked under the Urban Reserve Valuation Standard (URV-S) as a reserve asset. Environmental and tax credits are held outside every figure below, on purpose.

$3.6B
Gross Reserve Value under URV-S, struck at a 50% discount to forward market value
~$900M
Reserve NPV, plus a further $250M–$350M of CSA and other cash flows outside the reserve
$481M
Contracted Beneficiation Fee across the 30-year term at the full 400 TPD
~5×
Reserve increase on the 2,000 TPD expansion the counterparty has expressed interest in
Credits are excluded from all of the above.
Three components over 30 years, contracted separately under the CEAA: §45X production credits on synthetic graphite, monetized through §6418 transfers; durable sequestration attributes at $30 to $50 per tonne CO₂e; and methane avoidance of roughly 36,300 tonnes CO₂e a year at 400 TPD.
No prior round to reprice against.
The company originated through a Section 351 transfer into a Delaware corporation and has been founder funded since.
MANAGEMENT EXPECTS A THIRD-PARTY VALUATION OF $900M TO $1.3B. NO FORMAL APPRAISAL HAS BEEN PERFORMED. NOTHING IN THE NUMBER DEPENDS ON POLICY SURVIVING.

06 · EXIT

Same terms for everyone, on a clean cap table

Terms are set by the company and offered on the same basis to every participant. There is no lead investor pricing the round for everyone else.

01
$100M of Cornerstone Preferred Stock, Rule 506(c). Not a venture round, and not structured like one.
02
No lead investor, by design. A lead position concentrates term-setting power in one holder. We do not offer it.
03
A clean cap table. No venture money and no prior institutional round sits ahead of this one.
04
Liquidity route decided after close. Whether to enable a secondary market is a decision the company takes once the round is closed, not a promise made to sell it.
