Table of Contents

The  results  of  any  such  claims,  lawsuits,  arbitration  proceedings,  government  inquiries  and  investigations, 
executive  and  administrative  orders  and  directives,  or  other  legal,  regulatory,  and  administrative  actions  and 
proceedings  cannot  be  predicted  with  any  degree  of  certainty.  Any  claims,  lawsuits,  investigations,  orders, 
directives, regulatory actions, or proceedings against us, whether meritorious or not, could adversely affect our 
revenue,  cause  potential  customers  to  pause  sales  discussions,  cause  existing  customers  to  delay,  pause  or 
cancel contracts or seek to modify their contracts, undermine our ability to pursue future contracts, damage our 
relationships  with  partners  and  customers,  adversely  affect  our  institutional  standing,  undermine  investor 
confidence, limit our ability to sell our models, platform, and applications in certain industries, result in costly 
litigation  or  regulatory  or  other  defense,  adversely  affect  our  reputation,  require  significant  management 
attention, consume significant time, and divert significant resources. 

Determining reserves for our pending litigation or other disputes is a complex and fact-intensive process that 
requires  significant  subjective  judgment  and  speculation.  It  is  possible  that  a  resolution  of  one  or  more  such 
proceedings  could  result  in  substantial  damages,  settlement  costs,  fines,  and  penalties  that  could  adversely 
affect our business, financial condition, and results of operations. Because of the potential risks, expenses, and 
uncertainties of litigation or other dispute resolution processes, we may, from time to time, settle disputes, even 
where we have meritorious claims or defenses, by agreeing to settlement agreements, as we did, for example, in 
Bartz. Moreover, as in Bartz, insurance may not fully cover such claims, provide sufficient payments to cover all 
the  costs  to  resolve  one  or  more  such  claims,  or  continue  to  be  available  on  terms  acceptable  to  us.  A  claim 
brought  against  us  that  is  uninsured  or  underinsured  could  result  in  unanticipated  costs.  These  proceedings 
could also result in harm to our reputation and brand, sanctions, consent decrees, injunctions, or other orders 
requiring  a  change  in  our  business  practices.  Further,  under  certain  circumstances,  we  have  contractual  and 
other  legal  obligations  to  indemnify  and  to  incur  legal  expenses  on  behalf  of  our  business  and  commercial 
partners  and  current  and  former  directors  and  officers.  Any  of  these  consequences  could  adversely  affect  our 
business, financial condition, and results of operations.

We  are  subject  to  anti-corruption  and  anti-bribery  laws,  anti-money  laundering  laws,  and 
similar laws.

We are required to comply with the United States Foreign Corrupt Practices Act of 1977, the United Kingdom 
Bribery  Act  2010,  and  other  anti-corruption  and  anti-bribery  laws,  anti-money  laundering  laws,  and  similar 
laws  in  the  United  States  and  non-U.S.  countries  where  we  have  operations  and  conduct  business.  Anti-
corruption and anti-bribery laws, which have been enforced aggressively and are interpreted broadly, prohibit 
companies  and  their  employees,  agents,  intermediaries,  and  other  third  parties  from,  among  other  things, 
promising,  authorizing,  making,  or  offering  improper  payments  or  other  benefits  to  government  officials  and 
other persons in the public and private sector. 

We leverage third parties, including intermediaries and agents, to conduct our business and to sell our models, 
platform,  and  applications,  and  in  connection  with  lobbying  and  other  activities.  We  and  these  third  parties 
have  in  the  past  and  may  in  the  future  have  direct  or  indirect  interactions  with  officials  and  employees  of 
government agencies, including state-owned or state-affiliated entities, and we potentially could be held liable 
for  the  corrupt  or  other  illegal  activities  of  third-party  business  partners  and  intermediaries,  our  employees, 
representatives,  contractors,  partners,  agents,  and  other  third  parties,  even  if  we  do  not  explicitly  authorize 
such parties’ activities.

We cannot ensure that our policies and procedures to address compliance with these anti-corruption and anti-
money  laundering  laws  will  be  effective,  or  that  all  of  our  employees,  representatives,  contractors,  partners, 
agents, intermediaries, or other third parties have not taken, or will not take, actions that violate these laws, for 
which we may be ultimately held liable. 

As we increase our non-U.S. sales and business, our risk of violating these laws may increase. Noncompliance 
with applicable anti-corruption and anti-bribery laws, anti-money laundering, and similar laws could subject us 
to criminal or civil sanctions, settlements, prosecution, loss of export privileges, suspension or debarment from 
U.S.  government  contracts,  other  enforcement  actions,  disgorgement  of  profits,  significant  fines,  damages, 
other civil and criminal penalties or injunctions, whistleblower complaints, adverse media coverage, and other 
consequences.  Any  investigations,  actions,  or  sanctions  could  adversely  affect  our  reputation,  business, 
financial  condition,  and  results  of  operations.  Responding  to  any  investigation  or  action  could  result  in  a

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.
