A Delaware short-form merger under Section 253 of the General Corporation Law lets a parent corporation absorb a subsidiary by board resolution alone, with no shareholder vote, as long as the parent owns at least 90 percent of each class of the subsidiary’s outstanding voting stock. The parent’s board adopts the merger terms, files a Certificate of Ownership and Merger with the Delaware Secretary of State, and sends minority stockholders a post-merger notice telling them the deal is done and that their only recourse on price is an appraisal petition in the Court of Chancery.
The 90 Percent Ownership Threshold
Section 253 requires the parent to own at least 90 percent of the outstanding shares of every class of the subsidiary’s stock that would otherwise be entitled to vote on the merger.1Justia. Delaware Code 253 – Merger of Parent Corporation and Subsidiary Corporation or Corporations The test runs class by class. A subsidiary with both common and a Series A preferred means the parent needs 90 percent of each independently. Falling short on even one class closes the Section 253 door and pushes the deal into the longer Section 251 process, which requires board approval on both sides and a stockholder vote.
At least one party must be a Delaware corporation, but the parent itself can be organized elsewhere. The typical direction is the subsidiary merging up into the parent, and the walkthrough below assumes that structure.
Board Resolution and Certificate of Ownership and Merger
The parent’s board adopts a resolution authorizing the merger. The subsidiary’s board does not need to approve anything. The resolution must state the terms and conditions, including what minority stockholders receive for their shares, whether cash, stock in the surviving entity, or other property.1Justia. Delaware Code 253 – Merger of Parent Corporation and Subsidiary Corporation or Corporations It sets the effective date too. Leave that blank and the merger takes effect the moment the Secretary of State stamps the filing.
The board then prepares the Certificate of Ownership and Merger, which includes a copy of the resolution and the date it was adopted. The certificate identifies both corporations by name, state of incorporation, and date of organization. An authorized officer signs, with the signature line typed or printed beneath for legibility.2Delaware Division of Corporations. Certificate of Ownership and Merger Subsidiary into Parent Any outstanding Delaware franchise taxes owed by a subsidiary that will merge out of existence must be cleared before the Division will accept the filing.
Filing With the Secretary of State
The certificate is filed with the Delaware Division of Corporations. Under the August 2024 fee schedule, the filing fee is $259 for a one-page document, plus $9 for each additional page.3Delaware Division of Corporations. Certificate Type Fee Schedule Additional municipality fees may apply per corporation if registered agents sit in different municipalities.
Expedited processing is available in tiers:4Delaware Division of Corporations. Expedited Services
- Next-day service: $50 to $100, filed by 7:00 p.m. ET.
- Same-day service: $100 to $200, filed by 2:00 p.m. ET.
- Two-hour service: $500, filed by 7:00 p.m. ET.
- One-hour service: $1,000, filed by 9:00 p.m. ET.
Filings go through the state’s online portal or an authorized registered agent. Once the Division confirms compliance with Section 253, it issues a file-stamped copy. The merger becomes effective immediately on filing unless the certificate names a future effective date, and at that point all of the subsidiary’s property, rights, and obligations transfer to the surviving entity by operation of law.
Notice to Minority Stockholders
Because the vote is skipped, the disclosure burden moves to the back end. Under Section 262(d)(2), either the constituent corporation before the effective date or the surviving entity within 10 days after the effective date must notify every stockholder of each class entitled to appraisal rights that the merger has been approved and that appraisal is available.5Delaware Code Online. Title 8 Chapter 1 Subchapter IX
The notice must include either a complete copy of Section 262 or a reference to a publicly available electronic resource where stockholders can read it at no cost.5Delaware Code Online. Title 8 Chapter 1 Subchapter IX Most companies include the full text rather than fight later over whether a URL counted. The notice should also spell out the per-share merger consideration, instructions for surrendering stock certificates, and the deadline for demanding appraisal.
Disclosure is not a formality. The Delaware Supreme Court in Glassman v. Unocal Exploration Corp. held that although entire fairness review does not apply to short-form mergers, the duty to disclose all material facts bearing on the stockholder’s choice between accepting the price and seeking appraisal does.6Justia. Glassman et al v Unocal Exploration Corporation et al A deficient notice can expose the parent to a disclosure claim and, in some cases, a court-fashioned quasi-appraisal remedy that functions as an opt-out class action.
What the Minority Can Do: Appraisal Rights
A stockholder who thinks the merger price undervalues the shares can petition the Court of Chancery for an independent determination of fair value under Section 262.7Justia. Delaware Code 262 – Appraisal Rights In a short-form merger, this is almost always the only way to challenge the financial outcome.
Demand and Petition Deadlines
Within 20 days after receiving the notice of merger, the stockholder must deliver a written demand for appraisal to the surviving corporation. The stockholder must have held the shares continuously from the date of the demand through the effective date and must not have consented to the merger in writing. Either the surviving corporation or a qualifying stockholder may then file a petition in the Court of Chancery within 120 days after the effective date.7Justia. Delaware Code 262 – Appraisal Rights Miss the window and the stockholder is bound by the merger price.
Valuation and Interest
At trial, both sides present expert testimony on the going-concern value of the company. The court considers assets, market performance, and future earning potential but excludes any value created by the merger itself. Interest runs on the fair value amount from the effective date through payment at 5 percent over the Federal Reserve discount rate, compounded quarterly, unless the court finds good cause to deviate.7Justia. Delaware Code 262 – Appraisal Rights Appraisal cuts both ways: the court can find fair value below the merger price.
Why Fairness Lawsuits Rarely Work Here
Glassman removed the entire fairness test for Section 253 mergers. The court reasoned that the statute itself contemplates no negotiation, so demanding proof of fair dealing would contradict the summary nature of the procedure.6Justia. Glassman et al v Unocal Exploration Corporation et al What remains is a narrow review: whether the 90 percent threshold was met, whether the notice was adequate, and whether there was fraud or illegality. A minority stockholder cannot get an injunction to block the merger based on price alone, and the parent is not required to form a special committee or run a market check before setting the consideration.
Going-Private Filings if the Subsidiary Is Public
When a short-form merger eliminates a class of publicly traded equity securities, causing the subsidiary’s stock to be delisted or its SEC reporting obligations to become eligible for termination, the deal qualifies as a going-private transaction under SEC Rule 13e-3.8Legal Information Institute. 17 CFR 240.13e-3 – Going Private Transactions by Certain Issuers The parent or its affiliate must file a Schedule 13E-3 with all exhibits, amend it promptly if material information changes, and file a final amendment reporting the results.
Schedule 13E-3 requires detailed disclosures about the purpose of the merger, alternatives considered, the fairness of the transaction to unaffiliated stockholders, and any reports or opinions received from financial advisors. The federal obligation exists even though Delaware does not require a stockholder vote. Coordinate securities counsel early if the subsidiary is public.
Federal Tax Treatment
A short-form merger that absorbs a subsidiary into its parent generally qualifies as a tax-free liquidation under Section 332 of the Internal Revenue Code, provided the parent meets the ownership threshold in Section 1504(a)(2): at least 80 percent of the subsidiary’s total voting power and at least 80 percent of the total value of its stock.9Office of the Law Revision Counsel. 26 USC 1504 – Definitions The 90 percent Delaware threshold almost always clears this bar.
When Section 332 applies, the parent recognizes no gain or loss on receiving the subsidiary’s assets.10Legal Information Institute. 26 U.S. Code 332 – Complete Liquidations of Subsidiaries Under Section 334(b)(1), the parent takes the assets at the subsidiary’s existing tax basis rather than stepping up to fair market value.11Legal Information Institute. 26 U.S. Code 334 – Basis of Property Received in Liquidations
The subsidiary that merges out of existence must file IRS Form 966 within 30 days after the board resolution authorizing the merger is adopted, sent to the service center where the subsidiary files its income tax return.12Internal Revenue Service. Form 966 – Corporate Dissolution or Liquidation A final corporate tax return is also due for the subsidiary’s short tax year ending on the merger date. Missing these filings is a common post-closing oversight and generates avoidable IRS correspondence.
