#### Investment and cash generation

Base case

Capital spending **$667M**

Free cash flow **$502M**

Free cash flow: operating cash flow less capital spending.

- **The remaining annual investment plan sets the fourth-quarter spending need, mainly for optical capacity. Customer deposits help fund that capacity and support operating cash flow. Free cash flow reflects the cash left after capital spending; it can move differently from earnings as deposits and investment arrive. *4 of 6***
  - **Opus 5.5** Capital spending of about $2 billion sets the 2026 capex (about $0.7 billion in the fourth quarter).
  - **GLM 5.3** Capex of about $2 billion for 2026 sets my FY2026 capex base
  - **Kimi K3.1 Pro** capital spending of $2.0 billion and standard free cash flow of $2.29 billion
  - **DeepSeek V4.1 Flash** adopt the about $2 billion figure for 2026
  - **DeepSeek V4.1 Flash** Customer prepayments of $639 million in the first nine months are the reason operating cash flow can outrun a rising capital budget.
  - **Opus 5.5** Customer deposits fund capacity and lift operating cash flow; supports free cash flow growing despite higher capex.
  - **GLM 5.3** deposits are also why GAAP operating cash flow can stay strong alongside rising capex.
  - **Kimi K3.1 Pro** Customer deposits of $1.5 billion support the cash-flow forecast and reduce expansion risk.
