  • What changed: Mount Rainier Acquisition Corp. called a Special Meeting for February 27, 2023 at 3:00 p.m. Eastern Time, virtual, on a Second Extension Amendment moving the deadline from March 1, 2023 to March 31, 2023. Total consideration for the HUB Cyber Security business combination is expected to be approximately $226,885,000 of equity consideration, including trust funds and PIPE Financing commitments. The Merger Agreement's outside date, originally January 22, 2023, was extended to February 28, 2023. Why it matters: The deal is already approved and the redemption window has already run, so this one-month extension is purely about getting to closing before the merger agreement's own February 28, 2023 outside date — a very narrow margin. The $226,885,000 equity consideration includes trust cash that has already been reduced by the January redemptions, so what actually funds HUB depends on how many holders stayed. Failure to close by the outside date would let either party walk.

  • What changed: Mount Rainier Acquisition Corp. issued definitive merger materials for a special meeting on the Business Combination Agreement dated March 23, 2022, as amended on June 19, 2022, with HUB Cyber Security (Israel) Ltd. and Rover Merger Sub Inc. Merger Sub merges into RNER, which survives the merger and becomes a wholly owned subsidiary of HUB Security. The document is also a prospectus for up to 22,158,700 HUB Security ordinary shares, 17,846,200 warrants and 13,384,650 ordinary shares underlying those warrants. Why it matters: The consideration is engineered around a $10.00 share price that does not yet exist: HUB Security intends to effect a reverse stock split to bring its ordinary shares to $10.00 each, and the filing states the consideration will be adjusted if the split is not effected or produces a different price. Redemptions cut the pool directly — the numerator is $221,582,000 less the amounts payable on RNER Stockholder Redemptions, divided by $10.00. A $50,000,000 PIPE of 5,000,000 shares at $10.00 is conditioned on the transactions closing.

  • What changed: Mount Rainier Acquisition Corp. called a Special Meeting for December 21, 2022 at 5:00 p.m. Eastern Time, virtual, to extend the deadline from January 7, 2023 to March 1, 2023 and to amend the NTA Requirement. The Trust Account held approximately $177,921,896 of marketable securities as of December 2, 2022. Aggregate consideration for the HUB Cyber Security business combination, under the agreement dated March 23, 2022 and amended June 19, 2022, is expected to be approximately $226,885,000 of equity consideration, including trust funds and PIPE Financing commitments. Why it matters: Amending the net tangible asset requirement removes the floor that would otherwise stop redemptions from emptying the roughly $177.9 million trust before the HUB deal closes — it shifts risk from the sponsor to holders who stay. Because the $226,885,000 consideration includes trust cash, every redemption directly reduces what HUB actually receives. Redeeming at the pro rata trust portion is the alternative to funding a transaction whose economics depend on other holders staying.

Redemption deadlinethe last day to hand shares back for cash

Set by the filing that calls the meeting. Tender after it and the company is under no obligation to pay you the trust value.

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.
