The short version
Avalanche Treasury Corp (AVAT) closed its business combination with Mountain Lake Acquisition Corp. (MLAC) on June 11, 2026, officially becoming a publicly traded company. The deal included a roughly $216 million private placement, but 22,846,470 MLAC public shareholders redeemed their shares at about $10.62 each — draining nearly all of the trust account and leaving only about $1.63 million behind. Shares in the new combined company (Pubco Class A Stock) were distributed to former MLAC shareholders, private investors, and other deal participants, with certain shares subject to lock-up periods and earnout conditions tied to the stock price.
Filing impact
Filing sentiment
Avalanche Treasury Corp (ticker: AVAT) completed its previously announced merger with Mountain Lake Acquisition Corp. (MLAC), a blank-check company (also called a SPAC — a shell company created solely to take another company public), on June 11, 2026, according to an 8-K filing (a report companies file with the SEC to disclose major events) filed June 17, 2026.
How the Deal Was Structured
The transaction involved a series of steps. First, MLAC — originally a Cayman Islands company — converted itself into a Delaware corporation. Then two merger subsidiaries created by Avalanche Treasury Corp combined with MLAC and with Avalanche Treasury Company LLC (the operating company), leaving both as wholly-owned subsidiaries of the new publicly traded parent, referred to in the filing as "Pubco."
Former MLAC shareholders received one share of Pubco Class A common stock for each MLAC share they held. Holders of MLAC rights (certificates entitling them to a fraction of a share) received one share of Pubco Class A stock for every ten rights.
The Private Placement
Alongside the merger, the company raised approximately $216 million by selling company units at $10.00 each to private investors (a process known as a PIPE — private investment in public equity). Investors could pay in cash, USDC (a dollar-pegged digital currency), or AVAX (a cryptocurrency). Those units automatically converted into 21,855,658 shares of Pubco Class A stock when the merger closed.
Mass Redemptions Drained the Trust
A key development: holders of 22,846,470 MLAC public shares chose to redeem (cash out) their shares before the merger closed, receiving approximately $10.62 per share — totaling roughly $243.2 million returned to those shareholders. As a result, only about $1.63 million remained in the MLAC trust account for the company after the Closing, before paying any expenses.
Earnout Shares and Lock-Ups
-
Astral Horizon, L.P. received 4,000,000 shares of Pubco Class A stock as additional deal consideration. Of those, 2,000,000 shares (called "Earnout Shares") were placed in escrow and will only be released in thirds if the stock's 20-day average price (called VWAP — volume-weighted average price) hits $13.00, $15.00, and $17.00 per share at different points within five years of closing. The remaining 2,000,000 shares will be deposited into Astral's account 30 days after Closing.
-
The SPAC sponsor and certain MLAC insiders had 495,000 private placement shares and 4,387,500 Class B shares cancelled before the merger closed. An additional 1,600,000 "Sponsor Earnout Shares" were placed in escrow under the same $13/$15/$17 price milestones. If not all milestones are met by the fifth anniversary of closing, unearned sponsor shares could be transferred back to the company.
-
Approximately 10,605,639 shares of Pubco Class A stock and 5,805,639 shares of Pubco Class B stock are subject to lock-up agreements (restrictions preventing their sale) for 180 days after closing. Those restrictions can lift early if the stock's 20-day average price reaches or exceeds $12.50 per share.
New Governance and Registration Rights
Key individuals named in the filing — including Paul Grinberg and Doug Horlick — were appointed as representatives of certain shareholders under the escrow arrangements. Other named MLAC insiders include Jaime Vieser, John Norton, Michael Marquez, and Jeffrey Lager, along with entity SPAC Sponsor Capital Access.
All major shareholders, including the sponsor, seller-related parties (Dragonfly Digital Management, LLC and its affiliated funds), and Astral, received registration rights — meaning the company agreed to help them eventually sell their shares on the public market through a formal registration process.

Why it matters
AVAT's SPAC deal closed with an extraordinarily high redemption rate — nearly all public MLAC shareholders chose to take their money back rather than hold shares in the combined company, leaving just $1.63 million in the trust versus the roughly $243 million that walked out the door. This means AVAT's primary source of post-merger liquidity comes from the $216 million PIPE (private placement), not from the SPAC trust — a meaningful distinction because PIPE investors often have tighter lock-up terms and different incentives than typical public shareholders. Retail investors should also note the substantial overhang from earnout shares and locked-up stock that could eventually enter the market, as well as the price-milestone structure that ties large share releases to the stock trading well above its $10.00 deal price.
