- Indemnification (Part II Item 14): DGCL exculpation covers directors and officers except breaches of loyalty, bad faith or intentional misconduct, unlawful dividends/repurchases under DGCL Section 174 (directors), improper personal benefit, and (officers) actions by or in right of corporation. Bylaws effective immediately before offering completion provide indemnification to fullest extent permitted and mandatory advancement subject to limited exceptions. Indemnification agreements may be broader. Failure to satisfy PBC balancing obligations is not treated as bad faith or loyalty breach absent conflict of interest. D&O insurance maintained; no known pending indemnification litigation. Company says these provisions may discourage stockholder suits and increase costs borne by investors. Item 17 notes SEC position that Securities Act indemnification is against public policy and unenforceable.

## Gotchas
- Many figures are blank placeholders in this draft (offering price range, share counts, net proceeds, underwriting option size, commitment amounts, Run-Rate Revenue as of October 31, 2026, RSU values, pro forma data, lock-up share numbers, dilution); do not infer them.
- Broadcom lease rent figure differs between parts of the source (approx. $125.2 billion over five years excluding interest in the summary text vs approx. $161.2 billion aggregate rent excluding interest in the MD&A/contractual section); report both as stated and do not reconcile.
- Net loss in 2025 and 6M 2026 is driven mostly by non-cash change in fair value of convertible notes, derivative liabilities and SAFEs ($34.3B and $72.4B); operating loss and cash flows differ materially from net loss.
- Non-GAAP measures (Adjusted Operating Income/Margin, Adjusted Net Income) are company-defined; reconciliation is in MD&A. Run-Rate Revenue, NRR, customer counts and revenue per employee are internal metrics, not independently verified.
- Class F gives Founder LLC 50.1% of voting power on one share; Class T and Class F rights are disproportionate to economics; Class T and Class F sunset not subject to extension, delay or waiver once triggered.
- Class N shares are non-voting; company is a Nasdaq controlled company; NGC will not be fully independent.
- PBC balancing duties may negatively affect short-term or market price; limited Delaware precedent.
- Supply-chain-risk litigation ongoing with pending rehearing en banc petition; outcome unpredictable.
- Several exhibits and the underwriting agreement are to be filed by amendment; bylaws and charter take effect only immediately before offering completion.
- Interim six-month 2026 statements and several notes are unaudited; Ernst & Young audits FY2025 after change from Grant Thornton.
