What changed: DEFM14A by ORIGIN MATERIALS, INC. — the post-combination successor of Artius Acquisition Inc., which closed its merger with Micromidas, Inc. (Legacy Origin) on June 25, 2021. Despite the merger-proxy form code, it registers no securities and describes no combination: the special meeting on August 12, 2026, record date July 8, 2026, asks stockholders to approve the liquidation and dissolution of the Company under an Amended and Restated Plan of Complete Liquidation and Dissolution, plus an adjournment proposal. Why it matters: The board announced the dissolution on May 1, 2026 and unanimously recommends it. The Initial Liquidation Distribution to common stockholders is stated as expected to be between $0.61 and $3.54 per share, on 5,503,087 shares outstanding as of July 8, 2026 — a range the filing itself declines to narrow, citing the value realisable on remaining assets, the ultimate amount of liabilities and the amounts set aside for known, unknown or contingent claims. Shares remain saleable only until the Certificate of Dissolution is filed with the Delaware Secretary of State.
What changed: Origin Materials, Inc., the Artius Acquisition Inc. successor, filed as Exhibit 3.2 its Amended and Restated Bylaws effective July 6, 2026. The bylaws permit stockholder meetings to be held at a place determined by the board or, at the board's sole discretion, solely by remote communication under the Delaware General Corporation Law. The annual meeting is held on a date and at a time designated by the board, which may postpone, reschedule or cancel any previously scheduled annual meeting. Provisions on nominations of persons for election follow. Why it matters: Bylaw amendments are where the balance between board and stockholders is set, and the two provisions visible here favour the board: unilateral authority to postpone or cancel a scheduled annual meeting, and discretion to hold it virtual-only, which limits the floor engagement an activist can use. Nothing here touches a trust or a redemption right from the Artius vehicle. The advance-notice nomination terms that follow determine how hard it is to run a competing slate.
What changed: PREM14A by ORIGIN MATERIALS, INC., successor to Artius Acquisition Inc. — the preliminary version of the dissolution proxy made definitive ten days later as 0001802457-26-000052. Not a merger registration: the two substantive proposals are approval of the Amended and Restated Plan of Complete Liquidation and Dissolution and an adjournment proposal. The meeting date is still blank in this version; the record date is already fixed at July 8, 2026. Why it matters: Read against the definitive proxy of July 20, 2026, the money figure did not move: both state an Initial Liquidation Distribution expected to be between $0.61 and $3.54 per share on 5,503,087 shares outstanding as of July 8, 2026. This version also warns that if liabilities are higher than anticipated stockholders may receive no distribution at all, and that a contingency reserve must be provided for under the DGCL first. The definitive version adds the August 12, 2026 meeting date and one further incorporated Form 8-K514.
What changed: Origin Materials, Inc., the Artius Acquisition Inc. successor, held a special meeting on July 1, 2026 at which holders of 2,123,179 shares, 38.58% of the 5,503,087 shares outstanding at the May 20, 2026 record date, were present. Stockholders approved the Dissolution Proposal authorising the company to liquidate and dissolve under the Plan of Complete Liquidation and Dissolution, by 2,043,101 votes for, 66,752 against and 13,326 abstentions with no broker non-votes. A second proposal granted the board discretionary authority. Why it matters: This is the terminal vote for the Artius merger: stockholders have authorised the company to wind up under a plan of dissolution, so what remains for holders is whatever the liquidation distributes after creditors are paid. The margin was overwhelming, 96% of votes cast in favour, which usually means the alternative was seen as worse. With only 5,503,087 shares outstanding the company had already been heavily consolidated before reaching this point.
What changed: Origin Materials, Inc. filed as soliciting material a Form 8-K reporting that on June 10, 2026 it notified the Nasdaq Capital Market of its intention to voluntarily delist its common stock and deregister it with the SEC. Origin intends to file a Form 25 on or about June 22, 2026, with delisting expected to become effective July 2, 2026; Nasdaq is expected to file its own Form 25 to delist the warrants in connection with their expiration on June 24, 2026. Origin then intends to file a Form 15 on or about July 10, 2026. Why it matters: The delisting is a consequence of the plan of complete liquidation and dissolution the board approved, announced May 1, 2026, which remains subject to shareholder approval at a special meeting Origin intends to hold July 1, 2026 at 8:30 a.m. Pacific Time; the definitive proxy statement for it was filed May 26, 2026. Filing the Form 15 would terminate registration of the common stock and immediately suspend Origin's periodic reporting obligations under the Exchange Act, so this filing marks the point after which the public filing record on the company effectively stops.
What changed: Origin Materials, Inc. (successor to SPAC Artius Acquisition Inc.) called a special meeting for July 1, 2026 at 8:30 a.m. Pacific Time by webcast, record date May 20, 2026, proxy dated and first mailed May 26, 2026. On May 1, 2026 the company announced that after extensive consideration of strategic alternatives its board had unanimously approved the dissolution and liquidation of Origin Materials under a plan of complete liquidation and dissolution, subject to stockholder approval, and it has discontinued operations in connection with the plan. An adjournment proposal accompanies it. Why it matters: This is a wind-down vote on a business combination completed June 25, 2021 with Micromidas, so legacy Artius SPAC holders who did not redeem are being asked to approve the liquidation of what they exchanged their trust claim for. The financing history explains the outcome: a non-binding term sheet for $20 million announced in November 2025 failed to reach a definitive agreement, which the company disclosed in March 2026, because the lender materially reduced the valuation assumptions underlying the debt. Residual value to common depends on creditors being satisfied first.
What changed: Origin Materials, Inc. filed a preliminary proxy, subject to completion, for a Special Meeting of Stockholders to be held virtually at 8:30 a.m. Pacific Time on a date left blank throughout the document. Two proposals: approval of the liquidation and dissolution of the company pursuant to the Plan of Complete Liquidation and Dissolution attached as Annex A; and discretionary authority for the board to adjourn the meeting, even if a quorum is present, to solicit additional proxies if insufficient shares are voting in favour. The record date is May 20, 2026. Why it matters: The board unanimously recommends adoption of the Plan of Dissolution and the adjournment proposal. Because the meeting date is blank here, the only date this filing fixes is the May 20, 2026 record date; the definitive proxy statement that followed set the special meeting for July 1, 2026, as reported in accession 0001802457-26-000030. The adjournment authority is unusually broad in applying even when a quorum is present, which lets the board keep soliciting rather than put a losing dissolution vote to a count.

What changed: Origin Materials, Inc. (successor to SPAC Artius Acquisition Inc.) filed this definitive proxy on May 14, 2026 for a special meeting by live webcast at 8:30 a.m. Pacific Time on a date left blank in the document, record date May 20, 2026. On April 28, 2026 the board unanimously determined dissolution and liquidation was advisable, and on May 1, 2026 the company announced approval of a plan of complete liquidation and dissolution subject to stockholder approval. The Micromidas business combination closed June 25, 2021. Why it matters: The substance is a liquidation vote for a 2021 de-SPAC: stockholders are asked to approve winding the company up rather than any operating or sale alternative. The blank meeting date in the filed document means holders must track a later notice for the actual voting deadline, and the record date of May 20, 2026 already sets who is entitled to vote. For legacy Artius holders the trust redemption right was surrendered at closing, so recovery now depends entirely on residual assets after creditors, not on any per-share trust floor.
