Who is behind MLAC? Mountain Lake (Grinberg · Horlick)
The people who set Mountain Lake Acquisition Corp. up, what they have done before, and what happened to the shareholders who backed their earlier vehicles — every outcome cited to an SEC filing.
Post-close outcome quality: 1 priced deSPAC vs trust value (prior vehicles against the $10.00 IPO baseline, in-DB vehicles against the trust they filed): median -96%, 0/1 still worth at least half of trust, 1 at under a tenth of it. Worst: AVAT -96%. n=1, pulled toward neutral. 1 other completion(s) not priced (1 no stored price) — left OUT of the ratio, not guessed.
Mixed record · medium confidence — the same inputs always produce the same score.

Mountain Lake Acquisition Corp. II (MLAA) and RMG ML Sports Holdings (SHOT) share two Section 16 officers — Grinberg Paul and Horlick Douglas (CFO and President at both) — and SHOT's sponsor is literally named for the pairing ("RMG ML Sports Holdings Sponsor LLC"). DELIBERATE OMISSION: SHOT's sponsor is a joint venture with Riverside Management Group, whose own prior vehicles (RMG Acquisition Corp. → Romeo Power, RMG Acquisition Corp. II → ReNew Energy Global) are NOT booked here. RMG's principals (Mancini, Kassin) file nothing at Mountain Lake, so attributing RMG's record to this entity would be a claim the filings do not support.
Full sponsor record →Why the sponsor matters
The thirty-second version, for anyone who has never traded a SPAC.
A SPAC is an empty listed company; the sponsor is the only substance it has before a deal. They pick the target, negotiate the terms, and typically hold founder shares — equity they received nearly free — which pay off for them even in deals that lose public holders money. A sponsor’s prior vehicles are the closest thing to evidence about how this one ends.
How the founder-share incentive works is covered in our plain-English guide to the sponsor promote.
In plain English
Cash in trust / trust per sharethe cash the company is holding for each public share
Filed quarterly in the 10-Q's XBRL. It earns interest between filings, so the figure on a given day is slightly higher than the last filed one — where we show that we label it an estimate.
Dilutionhow much of the company new shares take from you
Sponsor promote, PIPE shares, warrants and rights all issue stock that did not pay $10 for it. The headline deal value is before that; the effective value is after.
De-SPACthe day the SPAC becomes the real company
The shares stop being a claim on a pot of cash and start being equity in an operating business. Roughly 80% of recent de-SPACs traded below $10 within a year.
