01 — PLATFORM ARCHITECTURE

One HoldCo. One SPV for every contract signed.

Carbotura Inc. is not a project. It is an origination and ownership engine, structured exactly as a Solar Independent Power Producer platform is: the parent holds the technology, the IP Tech Maintenance Fee entitlement and 100% of the equity, and every executed 30-year Circular Supply Agreement (CSA) instantiates a separate, bankruptcy-remote SPV owning one plant, one contract and one non-recourse debt stack.

02 — SPV 1 ECONOMICS · YORK COUNTY, PENNSYLVANIA · CONTRACTED

York County, Pennsylvania — 400 TPD

Three streams per SPV. Two carry the base case with circular materials at an average 50% price discount.

York County is contracted at 400 TPD across the 30-year term at the contracted rate of $75/ton. Figures are the attached August 2026 baseline model as run — including the four-year modular ramp — at Business Baseline pricing.

Urban Reserve, gross reserve value

$4,259.3M

A feedstock security instrument, not a margin line. It fixes 4.38M tons of input for three decades, which is what perfects the Urban Reserve and makes Streams 02 and 03 bankable.

Graphite alone is 57% of 30-year revenue — the largest single price exposure in the SPV. Hydrogen is consumed on-site in PEM fuel cells and is not sold.

New Business on Horizon (2027)

Everything to this point is contracted. What follows is not: two projects in origination and a wider US pipeline, each shown on its own terms and none of it in the contracted base case.

03 — SPV 2 · MIAMI-DADE COUNTY, FLORIDA · UNDER NEGOTIATION

Miami-Dade County, Florida — 500 TPD scaling to 3,000 TPD.

Shown as a range across the contracted build: the low end is the 500 TPD entry phase, the high end the 3,000 TPD contracted maximum. Both underwritten at the $100/ton target Beneficiation Fee with 2.5% annual escalation over 30 years, scaled from the attached 400 TPD model on throughput. Credits at zero.

STREAM 01

Reserve, carrying value

$771.1M → $4,626.9M

Reserve, gross value

$5,324.1M → $31,944.7M

A feedstock security instrument, not a margin line. The fee perfects title to between 5.47M and 32.85M tons over the term.

STREAM 02

Circular Materials sales

$5,549.9M → $33,299.2M

88.5% of baseline revenue at either end

Battery-grade graphite

$3,500.9M → $21,005.5M

Advanced carbon products

$718.1M → $4,308.8M

Refined DI water

$568.2M → $3,409.4M

Five remaining lines

$762.6M → $4,575.5M

Product mix and the 50% merchant pricing overlay are identical at both ends — everything scales linearly on throughput. Hydrogen is consumed on-site in PEM fuel cells and is not sold.

04 — SPV 3 · HILLSBOROUGH COUNTY, FLORIDA · UNDER NEGOTIATION

Hillsborough County, Florida — 500 TPD at $100/ton.

The same commercial template at 500 TPD, which is also the contracted maximum here — no ceiling has been agreed above it. Underwritten at the $100/ton target Beneficiation Fee with 2.5% escalation over 30 years, on the same model-scaled basis as slide 03. Credits at zero.
