Summary Consolidated Financial and Other Data 

The  following  tables  summarize  our  consolidated  financial  and  other  data.  We  have  derived  the  summary 
consolidated statements of operations data for the years ended December 31, 2023, 2024, and 2025 from our 
audited consolidated financial statements included elsewhere in this prospectus. We have derived the summary 
consolidated  statements  of  operations  data  for  the  six  months  ended  June  30,  2025  and  2026,  and  the 
summary  consolidated  balance  sheet  data  as  of  June  30,  2026,  from  our  unaudited  interim  consolidated 
financial  statements  included  elsewhere  in  this  prospectus.  The  summary  consolidated  financial  data  in  this 
section are not intended to replace our consolidated financial statements and related notes and are qualified in 
their entirety by our consolidated financial statements and related notes included elsewhere in this prospectus. 
Our  historical  results  are  not  necessarily  indicative  of  the  results  that  may  be  expected  in  the  future  and  our 
results  for  the  six  months  ended  June  30,  2026  are  not  necessarily  indicative  of  the  results  that  may  be 
expected for the full year ending December 31, 2026 or any other period. The following summary consolidated 
financial  and  other  data  should  be  read  in  conjunction  with  the  section  titled  “Management’s  Discussion  and 
Analysis  of  Financial  Condition  and  Results  of  Operations”  and  our  consolidated  financial  statements  and 
related notes thereto included elsewhere in this prospectus.

Includes  stock-based  compensation  expense  of $29  million,  $192  million,  and $1.2  billion  for  the  years  ended  December  31, 
2023,  2024,  and  2025,  respectively,  and $286  million  and $2.2  billion  for  the  six  months  ended  June  30,  2025  and  2026, 
respectively.
Includes  change  in  fair  value  of  convertible  notes,  derivative  liabilities,  and  simple  agreements  for  future  equity  (“SAFEs”), 
which  were $1.0 billion, $5.4 billion,  and $34.3 billion for the years ended December 31, 2023, 2024, and 2025, respectively, 
and  $10.9  billion  and $72.4  billion  for  the  six  months  ended  June  30,  2025  and  2026,  respectively.  These  changes  were 
primarily driven by an increase in the fair value of our outstanding convertible promissory notes resulting from an increase in 
our enterprise valuation during each of the respective periods.

How this was made

Read in full.
Kept in context.

A snapshot of the filing dated , 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.
