After a spin-off, vendor feeds keep serving the carve-out balance sheet — which omits the separation debt entirely

Claim

A spin-off's pre-distribution financials are prepared on a carve-out basis: the segment's own assets and liabilities as they sat inside the parent. The debt that makes the spin-co a standalone entity is raised at separation, typically to fund a cash dividend back to the parent. Vendor feeds ingest the carve-out statements first because they are what got filed, and they do not refresh until the spin-co files its own first 10-Q.

During that window the vendor balance sheet describes a company that no longer exists.

Evidence — HONA, 2026-08-06 (five weeks after the 2026-06-29 spin)

Metric	Vendor feed (carve-out)	Reality (Q2 release, as of 2026-06-27)	Error
Long-term debt	$271M	$15,849M	58x understated
Total equity	+$8.40B	−$5.623B (deficit)	Sign inverted
Cash	$213M	$1,057M	—
Debt / assets	1.53%	~82% of assets are liabilities	Unusable
Net debt / EBITDA	implied ~0x	~3.1x	Unusable

The cause is documented in the 8-K: HONA issued $16.0B of notes at separation and dividended ~$9.1B of the proceeds back to the parent. None of that appears in the carve-out because none of it existed while the business was a segment.

What this breaks, concretely:

• Graham's Intrinsic Value — √(22.5 × EPS × BVPS) returns a confident-looking number off the carve-out's positive BVPS. The real BVPS is −$17.74, and the model is inapplicable, not merely wrong. A carve-out feed hides that fact.
• P/B, ROE, ROA, Debt/Assets, interest coverage — all computed off the wrong denominators.
• Enterprise value — the single most important input to any multiple on a levered spin-co. HONA's EV is $64.4B against a $49.6B market cap; using the carve-out's near-zero net debt makes EV ≈ market cap and understates EV/EBIT by ~23%.
• FCF yield — carve-out FCF is pre-debt. HONA's carve-out showed $3.20B (2025) and $2.50B TTM; the standalone company pays ~$800–900M/yr of cash interest that never appears in the carve-out series. Management's own H2 guide of $1.0–1.5B is the real number.

How to apply

1. On any company spun off within the last two quarters, do not use the vendor balance sheet at all. Go to the first standalone earnings release or 10-Q. The balance sheet is usually in the press-release exhibit before the 10-Q is filed.
2. Find the separation debt in the 8-K, not the statements. The notes issuance and the size of the dividend back to the parent are disclosed there, and they tell you the leverage before any financial statement does.
3. Treat carve-out cash flow as pre-debt. Subtract a full year of interest on the separation debt before quoting any FCF yield. Or better: use the company's own first standalone FCF guide, which is already post-debt.
4. Negative equity on a fresh spin-co is a push-down artifact, not distress — but it does mean there is no book-value floor, and it means every book-based model is off the table. Say "inapplicable," don't substitute a fabricated BVPS.
5. The same window corrupts the parent. Post-spin, the parent's vendor revenue and earnings still include the spun segment until it is restated into discontinued operations. HON showed FY2025 revenue of $37.44B against an automation-only run-rate of ~$20B — so its P/S read 2.00x when the real EV/Sales was 4.7x.

What would falsify this

Nothing about the mechanism — it is an artifact of filing sequence, so it resolves on its own once the spin-co files a 10-Q. The note's value is entirely in the window, which is roughly one to two quarters. If a vendor ever ingests the 8-K debt disclosure directly, the window closes; no vendor observed doing so as of 2026-08.
