How to read this case page

Each deal's case page, tab by tab: what each block measures, how to read it, which signals warn and what to do about them. Values the page lacks read N/D: they are never estimated.

1. 1 · Tab: Header

   Header: ParentCo, SpinCo & Ratio

   Identifies the dual corporate relationship: the parent that spins off (ParentCo) versus the new independent listed company (SpinCo), the trading venue and the days since the announcement.

   What it is

   The identity panel of the separation. Unlike M&A, there are two resulting listed entities that share the value of the original corporation.

   How to read it

   Check the distribution ratio (Parent vs SpinCo tab) and the effective date or Distribution Date (Tax & when-issued tab). The parent's shareholders receive the shares at no cost.

   Red flags

   Complex structures in which the parent retains more than 20% of the subsidiary's capital, which can threaten tax-free treatment (Tax-Free Failure).

   Green flags

   Distribution of 80.1%+ to existing shareholders, securing tax-free status under IRS Section 355.

   What to do

   Work out how many SpinCo shares you are entitled to and watch for the start of forward (When-Issued) trading.

   Concepts and formulas (4)

   ParentCo (Parent) vs SpinCo (Spun-off Subsidiary)

   ParentCo is the originating corporation (e.g., General Electric); SpinCo is the separated division that starts trading on its own (e.g., GE HealthCare Technologies).

   Distribution Ratio

   Number of SpinCo shares the investor receives for each ParentCo share held (e.g., 1 SpinCo share for every N ParentCo shares held).

   Ex-Distribution Date (Ex-Date)

   First session in which ParentCo shares trade without the right to receive SpinCo shares.

   When-Issued (WI) Trading

   Conditional forward market that allows SpinCo shares to be traded before they are physically delivered to the securities account.

2. 2 · Tab: Summary

   Quantitative Telemetry: Dumping Floor & SOTP Discount

   Live trading price, discount to Sum-of-the-Parts value (SOTP), inelastic-selling floor after the first trading days and turnover volume.

   What it is

   The control panel that measures the divergence between the price depressed by institutional selling and the intrinsic value of the subsidiary's assets.

   How to read it

   Unlike M&A (where the spread is measured upwards to the offer), in spin-offs the spread is the 'SOTP Gap': the distance to the fair multiple of its pure-play peers. In our Summary («Genome & telemetry»), without an offer price the gross spread and the compound IRR appear as N/D; the unaffected price (T-1) carries its source and, without one, N/D: it is never estimated. The SOTP is found in the Parent vs SpinCo tab.

   Red flags

   Persistently record selling volume after 30 sessions: a symptom of undisclosed operating deterioration or loss of market share.

   Green flags

   A sharp contraction in trading volume between days T+10 and T+20 with price stabilisation: an unmistakable sign of a dumping floor.

   What to do

   The optimal buying point comes when daily volume falls back to its sector average and the price forms a solid base.

   Concepts and formulas (5)

   SOTP Target Value (Sum-of-the-Parts)

   Theoretical valuation of SpinCo applying the EV/EBITDA multiples of its pure-play competitors (e.g., Siemens Healthineers, Philips).

   SOTP Gap / Upside (%)

   Percentage revaluation potential from the depressed trading price to the SOTP fair value.

   SOTP Upside = ((SOTP Target - Spot) / Spot) × 100

   Dumping Floor

   Minimum price level at which index-fund supply is exhausted and value investors start buying.

   Peer Group EV/EBITDA Multiple

   Sector multiple of pure-play competitors used to estimate SpinCo's fair value, compared with the depressed multiple it falls to at its market debut.

   RAAS (case Summary)

   Risk-adjusted attractiveness shown in the Summary: it weighs the spread by the probability of success and the downside to the unaffected price. Without a sourced spread it appears as N/D.

   RAAS = P·Spread − (1−P)·Downside

3. 3 · Tab: Summary

   The Inverted Asymmetry of Spin-Offs Over Time

   In spin-offs the timing asymmetry is the reverse of M&A: the worst moment to buy is Delivery Day (Red Zone because of dumping) and the optimal moment is the floor at T+10/T+20 (Green Zone).

   What it is

   The conceptual model that keeps the investor out of the 'debut trap': buying on the day of the spin-off before passive funds have finished selling.

   How to read it

   The Red Zone sits at the Ex-Date, with a risk of a sharp fall. The Green Zone is triggered when dumping ends and the risk-reward asymmetry towards SOTP is at its maximum.

   Red flags

   Buying at the open on the Ex-Date while millions of ETF shares are still waiting to be sold in the closing auction.

   Green flags

   Entering after stabilisation in the Green Zone, with a valuation floor backed by positive free cash flow.

   What to do

   Set a reminder for day T+10 after the distribution and review the situation's case then.

   Concepts and formulas (4)

   Inverted Asymmetry of Spin-Offs

   Principle showing that risk peaks at the debut (T+0 to T+3) and is lowest once inelastic selling is exhausted (T+10 to T+20).

   Red Zone (T+0 to T+3: Maximum Dumping Risk)

   Period of blind selling by index funds; high probability of an immediate drawdown.

   Amber Zone (T+3 to T+10: Transition Phase)

   Institutional selling pressure slows and the float is progressively absorbed in the market.

   Green Zone (T+10 to T+25: Maximum Favourable Asymmetry)

   Valuation floor established; optimal risk-reward to capture the re-rating towards SOTP.

4. 4 · Tab: Critical path

   Spin-off Critical Path: From Form 10 to SOTP Re-Rating

   Timeline marking the calendar: Board Announcement -> SEC Form 10 -> Ex-Date & Dumping -> T+10 Floor -> SOTP Re-rating.

   What it is

   The mandatory procedural schedule that governs a corporate separation under SEC rules and corporate law.

   How to read it

   Follow the deal's progress: once the Ex-Date and the dumping phase are behind, the remaining critical milestone is the first standalone earnings report.

   Red flags

   Repeated delays in declaring the Form 10 effective because of SEC comments on the allocation of liabilities.

   Green flags

   Registration dates met on time, orderly start of When-Issued trading and closing on schedule.

   What to do

   Mark day T+10 after the distribution date in your calendar as the priority entry alert window.

   Concepts and formulas (3)

   Form 10 Filing (Registration Statement)

   Mandatory registration statement filed with the SEC describing SpinCo's assets, liabilities, corporate governance and pro-forma balance sheet.

   Form 10 Effectiveness

   Formal SEC clearance after the rounds of comments and responses on the audit of the separation are complete.

   T+10 Decontamination Period

   Time window after delivery in which the inelastic selling flow formally ends.

5. 5 · Tab: Thesis & checklist

   Editorial Thesis, Deconglomeration & Pure-Play Rationale

   Industrial rationale behind the break-up of General Electric: splitting aviation, healthcare and energy into 3 pure-play listed companies to unlock hidden value.

   What it is

   The strategic synthesis explaining why the subsidiary will be worth more on its own than inside the parent conglomerate.

   How to read it

   Pure-play companies attract specialist analysts and investors, can use their own shares as acquisition currency and allocate capital without cross-subsidies.

   Red flags

   Separations forced by activist pressure in which the subsidiary lacks the critical mass or scale to compete alone.

   Green flags

   Undisputed global leader in its niche (medical imaging and MRI technology) with a recurring customer base and high margins.

   What to do

   Prioritise SpinCos that lead their sector in market share and have been penalised only by the conglomerate stigma.

   Concepts and formulas (3)

   Pure-Play

   Company focused exclusively on a single line of business, with no conglomerate diversification diluting management's focus.

   Cross-Subsidisation

   Conglomerate malpractice of diverting profits from profitable divisions to fund loss-making ones.

   Autonomous Capital Allocation

   SpinCo management's ability to reinvest 100% of its cash flow in its own business without asking the parent for approval.

6. 6 · Tab: Thesis & checklist

   Spin-Off Forensic Checklist (10 Key Questions)

   Specialised control questionnaire in 5 thematic blocks auditing tax-free treatment, balance-sheet solvency, inelastic selling, standalone costs and management alignment.

   What it is

   The mandatory checklist tailored precisely to the mechanics and specific risks of corporate spin-offs.

   How to read it

   Go block by block to check whether SpinCo's balance sheet is protected and whether management has the right motivation to maximise the value of the stock.

   Red flags

   Answers revealing no firm tax exemption, excessive debt allocated to SpinCo or executives who stay at the parent with their wealth.

   Green flags

   Unconditional IRS 355 tax-free ruling, leverage below 2.5x EBITDA and a CEO with 100% of pay tied to the subsidiary's stock-market success.

   What to do

   Use this questionnaire before entering any SpinCo once the institutional dumping phase is over.

   Concepts and formulas (3)

   Spin-Off Forensic Checklist

   10-question protocol auditing taxation, leverage, institutional dumping, transition costs and insider purchases.

   Transferred Debt Audit

   Verifying that interest coverage ratios (EBITDA / Interest) ensure investment-grade strength.

   Forced ETF Selling

   Assessment of the share of SpinCo's float held by passive funds that cannot keep it under their mandate.

7. 7 · Tab: Market

   Institutional Decontamination Curve (Dumping Curve)

   Price curve showing the Ex-Date cut, the initial vertical fall driven by ETF selling and the sustained rebound towards SOTP value.

   What it is

   The graphic anatomy of institutional dumping. It lets you tell the blind-selling phase from the fundamental-accumulation phase at a glance.

   How to read it

   Watch the inverse correlation: during days T+1 to T+5 volume is huge and the price falls; between T+10 and T+20 volume dries up and the uptrend begins. In our case, the Market tab plots the real price series; if there is not enough history it shows N/D, never a synthetic series.

   Red flags

   No volume at the market debut, with a prolonged downward drift due to lack of liquidity or market interest.

   Green flags

   Massive volume from T+1 to T+3 that quickly purges forced holders, followed by firm technical support.

   What to do

   Do not buy at the open on Day 1; wait for daily volume to return to normal levels (between day T+10 and T+20).

   Concepts and formulas (4)

   Ex-Distribution Day (Day T+0)

   Official day on which the shares are delivered to shareholders' accounts and regular trading begins.

   Indigestion / Decontamination Phase

   Period of 2 to 4 weeks in which investors who do not want the subsidiary sell their position at non-fundamental prices.

   Inflection Point (T+10 / T+20 Floor)

   Price level at which institutional selling supply is exhausted and fundamental buyers take control.

   Multiple Re-Rating

   Gradual process by which the subsidiary moves from trading at a conglomerate discount to aligning with its pure-play peers.

8. 8 · Tab: Parent vs SpinCo

   Separation Genome: Debt, Standalone & Tax

   The fixed pillars of the Form 10 prospectus: allocation of financial debt between parent and subsidiary, standalone corporate costs and tax exemption.

   What it is

   SpinCo's financial 'birth certificate'. It reveals whether the parent used the subsidiary as a 'debt dump' to clean itself up or gave it a solvent investment-grade balance sheet.

   How to read it

   Check the resulting leverage ratio (Net Debt / EBITDA) and SpinCo's credit rating: moderate leverage with an investment-grade rating secures standalone viability. In the case, this tab gathers parent, SpinCo, distribution ratio, allocated debt and SOTP; the tax regime is in Tax & when-issued.

   Red flags

   Excessive leverage (>4.5x EBITDA) transferred to SpinCo combined with one-sided transition services agreements (TSA) in favour of the parent.

   Green flags

   Investment-grade rating, affordable standalone costs (<5% of EBITDA) and adequate starting cash.

   What to do

   If leverage is below 3.0x and tax-free status is firm, the subsidiary has proven solvency to withstand the dumping phase.

   Concepts and formulas (4)

   Tax-Free Status (IRC Section 355 / LSC)

   Binding ruling certifying that the share distribution is not taxed as a dividend at either the parent or the shareholder level.

   Allocated Debt and Special Dividend to the Parent

   Bonds issued by SpinCo whose cash proceeds are transferred to ParentCo as compensation before the separation.

   Standalone Overhead

   Additional recurring costs SpinCo must bear as an independent listed company (board, audit, listing, legal).

   Transition Services Agreements (TSA)

   Temporary contracts (12-24 months) under which the parent keeps providing IT, logistics or payroll services to SpinCo.

9. 9 · Tab: Parent vs SpinCo

   Entry Window at the Dumping Floor & Discount to Peers

   Weighs the potential of the re-rating towards SOTP value against the risk of operating transition friction or deterioration.

   What it is

   The analysis that determines whether entering at the dumping floor offers a clearly favourable risk-reward.

   How to read it

   Compare SpinCo's pro-forma EV/EBITDA multiple with that of its pure-play peers: the larger the discount and the firmer the probability of convergence, the more favourable the entry. The case does not compute an expected value of its own: it uses the RAAS in the Summary and the SOTP in this tab.

   Red flags

   Serious overruns in transition costs (TSA) that erode pro-forma EBITDA by more than 15% during the first year.

   Green flags

   SpinCo operating margins above the parent's and strict compliance with the deleveraging plan.

   What to do

   Check that the pro-forma Enterprise Value / EBITDA ratio offers at least 3 to 5 turns of discount to the peer group.

   Concepts and formulas (2)

   Conglomerate Discount

   Historical valuation penalty the division suffered while it was hidden inside the parent's balance sheet (e.g., General Electric).

   Audited Pro-Forma EBITDA

   SpinCo's adjusted operating profit taking into account the new standalone structure costs.

10. 10 · Tab: Tax & when-issued

    Mandate Mismatches & Insiders: Where the Dumping Comes From

    Review of the Form 10 prospectus: size mismatch (Cap-Size Mismatch), loss of dividend, index exclusion and insider purchases.

    What it is

    The forced-selling detector. It anticipates what share of the parent's institutional holders will be legally obliged to sell SpinCo. In the case it corresponds to the «Dumping & stabilisation» field in this tab, alongside the tax regime, the record date, the distribution date and the when-issued market.

    How to read it

    If the parent is an industrial giant paying a dividend (GE) and the subsidiary is a reinvesting healthcare company with no dividend (GEHC), forced selling will be extreme.

    Red flags

    The parent's senior management keeps all its shares in ParentCo and none of the key executives moves to SpinCo.

    Green flags

    The top CEO moves to SpinCo and 100% of their incentive plan is settled in shares of the new subsidiary.

    What to do

    Look for situations with heavy technical dumping but a management team strongly aligned through stock options.

    Concepts and formulas (4)

    Cap-Size Mismatch

    Occurs when a large-cap company spins off a small/mid-cap; funds that cannot hold mid-sized companies must sell.

    Dividend Yield Mismatch

    Dividend-focused funds immediately sell a SpinCo that pays no dividend.

    Index Exclusion

    Mechanical selling by passive ETFs tracking the parent's index, which the subsidiary does not join immediately.

    Insider Alignment (Form 4)

    Open-market share purchases made by SpinCo executives with their own money after the separation.
