The Five Disciplines of De-SPAC Success

What 699 Transactions Teach Us About Who Wins — and Why 85% Fail

Crocker Coulson | Founder & CEO, AUM Advisors June 2026 | Prepared for the SPAC Conference, June 9–10, 2026

Executive Summary

Five years after the excesses of the 2020–21 SPAC boom, the verdict from the data is unambiguous: de-SPAC transactions fail at a staggering rate. Only 14.9% of the 699 completed de-SPACs in our dataset are currently trading above the original $10 SPAC price. The median deal has lost 91 cents on every dollar invested. Seventy-nine companies — more than one in ten — are effectively at zero. And yet 104 companies have created genuine, lasting value. Vertiv is up 3,139%. IonQ is up 536%. Symbotic is up 429%. Intuitive Machines is up 249%. The question is not whether de-SPACs can work. The question is what the winners do differently — and whether those disciplines can be replicated. This paper argues that they can. Based on analysis of 699 completed transactions spanning 2010 to May 2026, supplemented by deep case study research on the most successful post-merger companies, we identify five disciplines that consistently separate winners from the 85% that fail. These are not structural advantages or luck. They are operational choices — made before the merger closes and executed consistently in the two years that follow.

The difference between the 104 companies that created value and the 595 that didn't is not market timing or sector luck. It is five disciplines, executed in sequence.

The Five Disciplines

01 Institutional-Quality Target Selection
02 Valuation Discipline
03 Public Company Operational Readiness
04 Robust Investor Communications — Years One and Two
05 The Compounding Effect: Analyst Coverage, Institutional Ownership, and Follow-On Capital

Each discipline is necessary but not sufficient on its own. The compounding effect — where strong target selection makes valuation discipline achievable, which makes institutional readiness credible, which makes investor communications effective, which makes follow-on capital accessible at premium prices — is what separates the occasional winner from the repeatable framework.

Part I: The Base Rate Problem

Any honest analysis of de-SPAC performance must begin with the aggregate data — and the aggregate data is damning. Of 699 completed de-SPAC transactions in the SPAC Insider universe through May 2026, only 104 are currently trading above the original $10 SPAC price, the clearest and most objective measure of post-merger value creation.

Redemptions: Still a Referendum, Still Brutal

The median completed deal saw 89% of trust shares redeemed, and half the cohort — 12 of 24 deals — lost more than 90% of trust to redemptions. The mean of 77% is flattered by a handful of remarkable outliers: two deals closed with zero redemptions (Boost Run and IQM Quantum Computers), and Infleqtion retained essentially its full trust at 0.09% redeemed.

The gap between the median (-91.4%) and the mean (-47.0%) tells an important story about the shape of the distribution. A small number of extraordinary winners — IonQ at +536%, Symbotic at +429%, Rocket Lab at +1,332%, Vertiv at +3,139% — pull the mean significantly above the median, while the overwhelming majority of deals cluster toward or at zero. For every company that becomes IonQ, there are more than twenty that effectively cease to exist as investable securities.

Three Eras, Three Distinct Failure Modes

The aggregate data masks important structural variation across three distinct market eras. Understanding each era's pathology is essential because the failure modes are different, and the applicable lessons differ accordingly.

The redemption vote has become the market's most honest referendum on deal quality. Every one of the three lowest-redemption deals trades above $10 today. Of the twelve deals that redeemed more than 90% of trust, exactly one trades above the IPO price; of the twelve that held redemptions at or below 90%, half do. Public SPAC holders, so often caricatured as yield-farming arbitrageurs, are proving to be rather adept at valuing these companies — at least the investors who remain holders at the redemption notice date.

PIPEs: The New Trust

Sixteen of the 24 completed deals — two-thirds — closed with PIPE financing, totaling $2.7 billion for the half. The median PIPE was $120 million; the mean of $169 million is skewed by a single $893 million outlier (StablecoinX). With median redemptions at 89%, the practical reality is that PIPEs are no longer supplementing trust capital — they are replacing it. The trust has become a listing mechanism; the PIPE is the actual financing.

Structure remains the exception, not the rule: 12 of the 16 closed PIPEs were straight equity at or near $10.00, while four carried structure — discounted ADSs with warrant coverage, units, or packages combining equity with convertible notes and preferred. The performance gap is instructive. The four structured deals trade at a median of roughly -57%, while the straight-equity cohort is essentially flat at a median of +2%. Structure is what a deal accepts when clean capital gives a pass, and the aftermarket trades the stock accordingly.

The starker split is simply having institutional capital at all. PIPE-backed deals trade at a median of -21%; deals that closed without a PIPE trade at a median of -59%. Committed institutional capital is simultaneously validation, float, and runway — and its absence is now close to disqualifying.

The Winners

Four of the seven winners are quantum computing companies — Horizon Quantum, Infleqtion, IQM, and Xanadu — and every one of them closed with a PIPE of $100 million or more. The quantum cohort is the clearest expression of the scarcity premium in today's market: a small number of genuinely differentiated, deep-science assets that public investors cannot access any other way. IQM, the Finnish quantum hardware leader, closed on July 1 with zero redemptions and an upsized $145 million PIPE that brought in Finnish pension institution Ilmarinen alongside existing holders — a model of how a European deep-tech company can use the de-SPAC route to reach US capital with institutional validation intact. Whether every quantum valuation proves durable is a question for the coming quarters; that the market is differentiating real technology platforms from story stocks is not.

Part III: Three Case Studies

Horizon Quantum: The Premium PIPE

On paper, dMY Squared's merger with Singapore-based Horizon Quantum looked like a redemption casualty: 85% of trust shares redeemed, leaving roughly $11 million of cash. What the redemption number missed was the quality of the capital that stayed and arrived. The $109 million PIPE priced at $11.82 — a premium to trust value — with an 18-month lockup and strategic participation from IonQ, the most successful quantum de-SPAC of the prior generation. A PIPE priced above NAV with long lockups is the single strongest signal a de-SPAC can send: sophisticated investors underwriting the long-term equity story with conviction. The stock trades near $24, up 138%.

Suncrete: The Full Toolkit

Haymaker Acquisition Corp. 4's merger with Suncrete shows what disciplined deal engineering looks like in the post-reform era. A private equity–backed roll-up of Sunbelt ready-mix concrete operations — a real industrial business with substantial revenue, consolidating a fragmented, mission-critical industry in the middle of a generational ownership transfer. Redemptions held to 56.5% — dramatically below the 89% median. A PIPE upsized from $105 million to $167 million on demand, layered with $51 million in non-redemption agreements and a $58 million forward purchase commitment. And within weeks of closing, a warrant exchange offer that cleaned up the capital structure — removing the overhang that has suppressed so many post-merger equities. Every one of the Five Disciplines is visible here, and the market has paid for it: +89%. Suncrete may also preview where the next cohort of winners comes from: cash-generative consolidation platforms in unglamorous sectors, where a public currency is an acquisition tool rather than an exit.

StablecoinX: Capital Is Not a Strategy

The largest PIPE of the half — $893 million, from a roster of prominent crypto investors — belongs to a deal trading down roughly 80%. TLGY Acquisition's combination with StablecoinX, a digital-asset treasury vehicle, closed in June with 99.6% of trust redeemed after a four-and-a-half-year SPAC life spanning eight extensions and a terminated prior deal. The lesson is one the 2021 cohort taught and the market keeps re-learning: capital raised is not value created. A nine-figure PIPE can fund a balance sheet, but it cannot substitute for a compounding operating story that gives public investors a reason to hold. The de-SPACs that work are businesses first and financings second.

At the other end of the capitalization spectrum sits the half's worst performer: an $8 million PIPE atop a $1.5 million post-redemption trust, now trading down 96%. Undercapitalized deals do not get a second chance in this market.

Geography: The Cross-Border Half

Perhaps the most underappreciated feature of the current cycle: 43% of announced H1 2026 targets — 20 of 47 — are headquartered outside the United States, spanning eight European targets (France, Switzerland, the UK, Ireland, the Netherlands, Poland), eight across Asia-Pacific (Hong Kong, Singapore, Taiwan, South Korea, Australia), three in Canada, and one in the Middle East. Among completed deals, nine of 24 targets were international — including the half's Finnish, Singaporean, and Canadian quantum winners. The de-SPAC has quietly become one of the principal on-ramps for international companies seeking US listings, valuations, and liquidity — a theme we expect to strengthen as European critical minerals, defense technology, and deep-science companies weigh their venue options.

What It Means

Three conclusions from the first half, each of which we will test again in Q3:

1. The bifurcation is real and accelerating. A 29% above-$10 rate — against a 15% historical base — does not mean de-SPACs have become safe. It means the market has become more efficient at sorting them, and the sorting now happens early: in the redemption vote, in the PIPE book, and in the premium to redemption value before closing.

2. The PIPE is the deal. With trusts redeeming away at a median of 89%, committed institutional capital has become the de facto financing event, the validation signal, and the strongest single predictor of aftermarket performance in our H1 data. Terms matter as much as size: straight equity at or above trust is a vote of confidence; structure is a warning label.

3. Scarcity beats supply. In completed-deal performance, the winners are concentrated in assets public markets cannot otherwise reach: quantum computing platforms, differentiated deep science, and international leaders making their US debut — plus, in Suncrete’s case, a cash-generative industrial consolidator. In the announced pipeline, conviction premiums attach to two names — a category-defining robotics platform and a clinical-stage biotech — while the crowded middle trades at cash. Scarcity earns a bid; supply earns a listing.

The Scorecard will return after the third quarter with the same lens: not how many SPACs launched, but which combinations created value — and why.
