third-party  data  published  about  us  or  other  companies  in  our  industry,  whether  or  not  such  data  is 
accurate;

announcements by us or our competitors of new models, platforms, or applications;

the public’s reaction to our press releases, other public announcements, and filings with the SEC;

fluctuations in the trading volume of shares of our Class A common stock or the size of our public float;

short selling of our Class A common stock or related derivative securities;

actual or anticipated changes or fluctuations in our results of operations;

actual  or  anticipated  developments  in  our  business,  our  competitors’  businesses,  or  the  competitive 
landscape generally;

changes in the anticipated future size or growth rate of our addressable markets;

our issuance of shares of our Class A common stock, including as a result of the conversion of our Class 
N common stock in connection with certain transfers;

litigation or regulatory action involving us, our industry, or both, or investigations by regulators into 
our operations or those of our competitors;

developments or disputes concerning our intellectual property or other proprietary rights;

announced  or  completed  acquisitions  of  businesses  or  technologies,  or  similar  strategic  transactions, 
by us or our competitors;

new  laws  or  regulations  or  new  interpretations  of  existing  laws  or  regulations  applicable  to  our 
business;

regulatory  enforcement  actions  or  other  governmental  efforts  affecting  our  models,  platform,  and 
applications;

changes in accounting standards, policies, guidelines, interpretations, or principles;

• major catastrophic events such as war, incidents of terrorism, pandemics, or responses to such events;

•

•

any additions or departures of founders, board members, management, or key personnel; and

general economic conditions and slow or negative growth of our markets.

In  addition,  if  the  market  for  technology  stocks  or  the  stock  market  in  general  experiences  a  loss  of  investor 
confidence, the market price of our Class A common stock may decline for reasons unrelated to our business, 
financial condition, or results of operations. The market price of our Class A common stock may also decline in 
reaction  to  events  that  affect  other  companies  in  our  industry  even  if  these  events  do  not  directly  affect  us. 
Accordingly, we cannot assure you of the liquidity of any trading market, your ability to sell your shares of our 
Class A common stock when desired, or the prices that you may obtain for your shares of our Class A common 
stock.

In the past, stockholders have initiated securities class action lawsuits against companies following periods of 
stock price volatility. If the market price of our Class A common stock is volatile, we may become the target of 
securities  litigation.  Such  litigation  may  subject  us  to  substantial  costs,  divert  resources  and  management’s 
attention, and adversely affect our business, financial condition, and results of operations.

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.
