The offering, unpacked.
Arm’s offering consisted of ADSs sold by an existing shareholder. The release carries a September 14 webpage label and a September 13 announcement dateline; the latter is used for pricing here.
The company did not receive proceeds from the selling shareholder’s base offering. Multiplying the full offered quantity by the price measures transaction size, not capital raised by Arm.
How the base size is calculated
95,500,000 securities × $51.00 = $4,870,500,000
Base offering size combines the value of securities sold by the company and by any selling shareholders. It excludes the additional-share option. A headline that calls every dollar “money raised by the company” can therefore describe a different figure.
The quoted price applies to the security described in the offering. It is not a current market price, a valuation target, or evidence of an investment return. The first trading date is the date announced in the pricing release, rather than a claim that an offering calendar was continuously monitored.

From facts to better questions
Research beyond the offer price.
How do licensing and royalty economics respond to customer demand and product mix?
This is a research question, not a conclusion about current operating performance. Use the prospectus and subsequent filings to assemble an answer.
1
Read the business model
Identify who pays, what they buy, and which costs scale with demand. Compare the narrative with the financial statements.
2
Trace ownership and proceeds
Separate company-issued securities from selling-holder transactions. Read the capitalization and use-of-proceeds sections together.
3
Define your comparison
Choose a price baseline and time window before calculating returns. Historical offer terms alone do not establish performance.
Keep the research going.
