people across our technology team were working like
software developers. We have a mantra now: ‘If you can
imagine it, Claude can code it for you’ The enablement,
simplification, and efficiency we’ve achieved in just a few
months is amazing.”

Yago Tenorio, SVP and Chief Technology Officer at Verizon

How this was made

Read in full.
Kept in context.

A snapshot of the filing dated October 26, 2026, rather than a live record of later events.

The review

Three primary reviewers read non-overlapping ranges of the complete main filing. All 43 embedded image instances were transcribed and visually reviewed, including the founders’ letter, charts, and customer case studies. Financial tables were also checked visually for dates, units, and column alignment.

A separate reviewer checked the draft’s calculations, accounting interpretations, and customer qualifications. An additional check covered the later merged findings. The result is 62 findings and 21 customer examples.

The boundary

Companion contracts and other exhibits named in the filing’s index are separate documents and were not independently reviewed. Customer outcomes, technical benchmarks, forecasts, and scientific priority claims remain attributed company or customer disclosures.

The numbers

Dollar figures are U.S. dollars. H1 means the six months ended June 30; Q2 means the three months ended June 30. The 2026 interim financial statements are unaudited. Our calculations show their inputs and are labeled separately from reported values.

Blank fields stay undisclosed. Figures with different periods, conditions, or potentially overlapping scopes are kept separate. An earlier tender price is not an IPO price.

What the evidence labels mean

Reported in filing: A company disclosure, with the period and accounting basis retained.
Company estimate / company claim: An estimate or assertion attributed to the company, with its uncertainty preserved.
Our calculation: A derived figure using cited inputs. It is not a separately reported company metric.
Customer example: A selected case study, with its measurement limits. It is not representative ROI.
Proposed / conditional: A status qualifier for an arrangement that is not yet effective or depends on stated conditions.

About updates. This edition is tied to the October 26, 2026 filing. Any later revision should identify its new source date and preserve the basis of earlier claims.
