Anthropic S-1: Will $2.7B Adjusted Net Income Draw SEC Comments?

Anthropic S-1: Will $2.7 Billion of Adjusted Net Income Draw SEC Comments?

Anthropic's S-1 turns an $80.7 billion net loss for the first half of 2026 into $2.7 billion of Adjusted Net Income. SEC rules permit that if net loss gets equal or greater prominence, the filing reconciles the two, and the measure doesn't mislead. Fair value changes make up 97% of the bridge and sit outside the staff's main "misleading" example, so we read the open points as smaller ones; any comment is the staff's call.

Key takeaways

• Two fair value lines, $72.4 billion on convertible notes and $8.7 billion on "certain mark-to-market financial instruments," make up $81.1 billion of the $83.4 billion in adjustments.
• Both reconciliations start from GAAP, in line with the staff's prominence examples in C&DI 102.10.
• A comment could ask what the mark-to-market instruments are, what the tax effect is, and why the charitable charges and the 2025 Bartz settlement fall outside ongoing operations.

What the S-1 reports

Anthropic, PBC publicly filed its registration statement on Form S-1 on October 26, 2026. Its MD&A says excluding items "not directly reflective of the ongoing operating performance of our business" gives "a more consistent and comparable overview of our financial performance across periods." The Wall Street Journal reported on the adjusted-profit figure on October 28.

The reconciliations for the six months ended June 30, 2026 (in millions; unaudited):

Both definitions also exclude the $1.5 billion Bartz copyright settlement, which Anthropic recorded in 2025.

The rules

Item 10(e) of Regulation S-K requires the most directly comparable GAAP measure "with equal or greater prominence" and a reconciliation. It bars smoothing items "identified as non-recurring, infrequent or unusual" when a similar charge is reasonably likely within two years or occurred in the prior two. Rule 100(b) of Regulation G adds the misleading test, and the staff's non-GAAP C&DIs show how it applies both.

Adjustment by adjustment

Convertible notes, $72.4 billion. C&DI 100.01's example of a measure that could mislead is one that "excludes normal, recurring, cash operating expenses necessary to operate a registrant's business." This charge is non-cash and comes from remeasuring financing instruments below operating loss, so we read it as outside that example, although it appears in every period presented. The definition removes "the change in fair value" whichever way it moves, which on its face addresses C&DI 100.03 on excluding charges but not gains. C&DI 100.04 targets adjustments that replace GAAP recognition with another method, such as cash-basis accounting, and we don't read this exclusion as one. Our convertible note analysis covers the charge itself.

"Certain" mark-to-market instruments, $8.7 billion. The definition doesn't name them. The cash flow statement shows the same $8,720 million as "Recognition and change in fair value of other financial instruments." Other income (expense), net lists a $9,405 million charge on note purchase agreements, a $39 million holdback loss and a $724 million gain on warrant rights, which net to $8,720 million by our arithmetic. Note 4 says Anthropic's 2026 note purchase agreements with Google and Amazon are "marked-to-market each period." If so, the adjustment removes a gain along with the losses. A comment could still ask Anthropic to name the instruments and explain "certain."

Stock-based compensation, $2.2 billion. The C&DIs don't address it by name, and as a non-cash charge it sits outside the 100.01 example.

Non-cash charitable contributions, $126 million. Anthropic matches employee donations with Class N common stock. C&DI 100.01 also weighs how an expense relates to "business strategy," and the S-1 calls the program "a meaningful expression of the Company Purpose." A comment could ask why a charge tied to strategy belongs outside ongoing operations.

Bartz settlement, $1.5 billion (2025). The S-1 calls it "not indicative of ongoing operations" and avoids the words "non-recurring, infrequent or unusual," which C&DI 102.03 says is what triggers the Item 10(e) bar. C&DI 100.01 still treats an expense that occurs "occasionally, including at irregular intervals" as recurring, and the S-1 lists other pending copyright suits. It is a cash charge: Anthropic paid $300 million in 2025 and carried $1.2 billion in current liabilities at June 30, 2026.

Income taxes. C&DI 102.11 says a performance measure should include tax expense "commensurate with the non-GAAP measure of profitability," shown as a separate adjustment. Neither reconciliation has a tax line. Anthropic keeps a full valuation allowance and calls its $21 million half-year provision not material, which may explain a nil effect. A comment could ask the S-1 to say so.

Fina tested the same reconciliation against the C&DIs: Fina's cited analysis of Anthropic's non-GAAP measures.

Prominence and labels

C&DI 102.10 treats a non-GAAP measure as more prominent if it comes before the GAAP measure, opens the reconciliation, or gets discussion the GAAP figure doesn't. In the sections we read, the S-1 avoids all three. Its summary shows operating loss and net loss before the non-GAAP table, and the MD&A overview states the $693 million operating loss before the $1.6 billion of Adjusted Operating Income. We did not review the prospectus graphics.

The summary's non-GAAP table could still draw a question: it lists Adjusted Net Income without net loss beside it and points to MD&A for the reconciliation. Under C&DI 100.05 on labels, the staff could also ask whether "Net Income" fits a figure that removes $81.1 billion of net fair value charges.

When a staff comment would show up

EDGAR lists no staff correspondence for Anthropic as of October 30, 2026. The SEC releases review letters no sooner than 20 business days after it declares a registration statement effective. Until then, a comment would show up as a change to the reconciliation in an S-1/A. Our non-GAAP compliance guide covers the rules, and our review of 2026 non-GAAP comment letters sets out the patterns the staff is flagging.
