In March 2026, the Company entered into a lease agreement for a data center to be constructed. The 
lease is expected to commence in 2027 and is for a term of 20 years from the date the data center is 
delivered to the Company.

In March 2026, in connection with an agreement to lease compute and infrastructure equipment, the 
Company  entered  into  a  note  purchase  agreement  under  which  the  Company  may  issue,  subject  to 
certain  conditions,  up  to  $42.0  billion  of  convertible  promissory  notes  in  the  future  solely  to  finance 
rent obligations under the lease.

In March 2026, in connection with order forms executed under the Company’s amended and restated 
colocation  and  services  agreement  with  a  data  center  provider  for  a  facility  in  the  United  States,  the 
Company  entered  into  a  guaranty  of  the  provider’s  obligations  under  a  power  purchase  contract  in 
favor of the power counterparty in a maximum amount of up to $500 million.

In  April  2026,  the  Company deposited  $2.5  billion  into  an  escrow  account  in  connection  with  a 
compute and infrastructure lease agreement.

Subsequent  to  December  31,  2025,  the  Company  entered  into  new,  and  amended  existing,  lease  and 
commercial  agreements  primarily  to  secure  additional  compute  and  infrastructure  capacity,  with 
aggregate future minimum payment obligations of approximately $417 billion. These primarily consist 
of  leases  for  compute  equipment  and  data  centers  and  purchase  commitments  with  certain  cloud 
providers,  commencing  between  2026  and  2027  with  terms  ranging  from  less  than  one  year  to  20 
years. The Company also expanded certain existing commercial agreements under which it expects to 
secure  additional  compute  and  infrastructure  capacity  to  be  delivered  between  2028  and  2031.  As 
certain  commercial  terms  have  not  yet  been  finalized,  the  Company  estimates  aggregate  future 
payments under these agreements to be approximately $125 billion to $150 billion.

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.
