Rhea-AI Filing Summary

Forte Biosciences, Inc. (FBRX) has been acquired by argenx BV through a cash tender offer followed by a merger. Avena Merger Sub Inc., a wholly owned subsidiary of argenx, commenced a tender offer at $77.00 per share in cash for all outstanding Forte common shares.

As of one minute after 11:59 p.m. Eastern Time on August 26, 2026, 19,894,879 shares had been validly tendered and not withdrawn, which, together with shares already owned by argenx, represented approximately 87.13% of Forte’s outstanding shares, satisfying all offer conditions. These shares were irrevocably accepted for payment, and on August 27, 2026, the merger was completed under Section 251(h) of the DGCL, making Forte a wholly owned subsidiary of argenx.

Each remaining share (other than specified excluded and appraisal shares) was converted into the right to receive the same $77.00 cash consideration, and holders of outstanding pre-funded warrants became entitled, upon exercise, to receive the merger consideration for the underlying shares. The acquirer used approximately $2.2 billion of cash on hand to fund the offer, equity awards, pre-funded warrants and related payments. Forte has requested that Nasdaq suspend trading and file Form 25 to delist the shares and plans to file Form 15 to terminate registration and suspend its Exchange Act reporting obligations. All pre-merger directors and officers resigned at the effective time and were replaced by the former directors and officers of Purchaser.

At the August 27, 2026 effective time, the completed merger made Forte Biosciences a wholly owned subsidiary of argenx; its certificate of incorporation and bylaws were amended and restated in full.

Each outstanding, unexercised pre-funded warrant retained the right, upon exercise, to receive the merger consideration for each underlying share, without the warrant’s exercise limitations; a pre-funded warrant converts to shares when exercised.

Exchange Act Sections Sections 12(b), 12(g), 13 and 15(d) Sections under which Forte is seeking delisting and termination or suspension of reporting
tender offer financial
"Purchaser commenced a tender offer (the “Offer”) to purchase all of the Company’s issued and outstanding shares"
A tender offer is a proposal made by a person or company to buy shares from existing shareholders at a set price, usually higher than the current market value, within a specific time frame. It matters to investors because it can lead to a change in ownership or control of a company, and shareholders must decide whether to sell their shares at the offered price.
Merger Agreement regulatory
"the Company entered into an Agreement and Plan of Merger, dated as of July 26, 2026 (the “Merger Agreement”)"
A merger agreement is a binding contract that lays out the exact terms for two companies to combine, including the price, what each side will deliver, and the conditions that must be met before the deal is completed. Investors care because it sets the timetable, payouts and risks — like a blueprint or prenup that shows whether the deal is likely to close, how ownership will change, and what could cancel or alter the payout they expect.
Merger Consideration financial
"was converted into the right to receive the Offer Price in cash (the “Merger Consideration”)"
Merger consideration is the total payment a company or buyer offers to shareholders of a target company in exchange for combining the two businesses, and can include cash, shares in the surviving company, debt assumption, or a mix of these. Investors care because the form and amount affect the deal’s value, tax consequences, immediate cash received versus future ownership, and the risk and upside of holding new shares — similar to choosing between cash now or stock that could grow later.
Section 251(h) of the DGCL regulatory
"The Merger was completed pursuant to Section 251(h) of the DGCL, without a meeting or vote"
Form 25 regulatory
"requested that NASDAQ suspend trading of Shares and file with the SEC a Form 25 Notification of Removal"
A Form 25 is an official filing with the U.S. Securities and Exchange Commission used to remove a company's stock or other security from a national exchange list. Investors should care because delisting often means less visibility, lower trading volume and wider price swings—similar to a product moving from a major supermarket to a small local market, which can make buying, selling and valuing the security more difficult.
Form 15 regulatory
"The Company also intends to file with the SEC a Certification and Notice of Termination of Registration on Form 15"
A Form 15 is a short filing a public company uses with the U.S. Securities and Exchange Commission to stop or pause its routine public reporting requirements when it meets certain legal thresholds (such as a low number of public shareholders) or other qualifying conditions. Investors should care because filing one typically means less public financial information and lower trading liquidity—similar to a shop taking down its public notice board, making it harder to track performance and buy or sell shares.

Introductory Note.

As previously disclosed on July 26, 2026 in the Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) by Forte Biosciences, Inc., a Delaware corporation (the “Company”), the Company entered into an Agreement and Plan of Merger, dated as of July 26, 2026 (the “Merger Agreement”), by and among the Company, argenx BV, a private company with limited liability (besloten vennootschap) organized under Belgian law (“Parent”), and Avena Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Purchaser”).

Item 2.01.
Completion of Acquisition or Disposition of Assets.

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions described therein and in the Offer to Purchase, dated August 6, 2026, and the related Letter of Transmittal, on August 6, 2026, Purchaser commenced a tender offer (the “Offer”) to purchase all of the Company’s issued and outstanding shares of common stock, par value $0.001 per share (“Shares”), at a price per Share of $77.00 per Share, net to the seller in cash, without interest (the “Offer Price”), subject to any withholding tax.

The Offer expired at one minute after 11:59 p.m., Eastern Time, on August 26, 2026 (the “Expiration Date”). According to Computershare Trust Company, N.A., the depositary and paying agent for the Offer, as of the Expiration Date, 19,894,879 Shares were validly tendered and not validly withdrawn in the Offer, representing, together with Shares already owned by Parent, approximately 87.13% of the outstanding Shares. The number of Shares tendered satisfied the condition to the Offer that there be validly tendered, and not validly withdrawn, in the Offer a number of Shares that, considered together with all other Shares owned by Purchaser and its “affiliates” (as such term is defined in Section 251(h)(6) of the Delaware General Corporation Law, as amended (“DGCL”)), represent one more Share than 50% of the total number of Shares outstanding as of immediately following the “consummation” (as such term is defined in Section 251(h)(6) of the DGCL) of the Offer. All other conditions to the Offer were satisfied or waived as of the Expiration Date. As a result, following the Expiration Date, Purchaser irrevocably accepted for payment (the time of such acceptance, the “Offer Acceptance Time”), and will promptly pay for, all Shares tendered and not validly withdrawn pursuant to the Offer in accordance with the terms of the Offer and the Merger Agreement.
 
Following the consummation of the Offer, the remaining conditions to the Merger (as defined below) set forth in the Merger Agreement were satisfied or waived, and on August 27, 2026, Purchaser merged with and into the Company (the “Merger” and, together with the Offer and the other transactions contemplated by the Merger Agreement, the “Transactions”), with the Company continuing as the surviving corporation and a wholly owned subsidiary of Parent. The Merger was completed pursuant to Section 251(h) of the DGCL, without a meeting or vote of the Company’s stockholders. Pursuant to the Merger, each Share outstanding immediately prior to the effective time of the Merger (the “Effective Time”) (other than (i) (a) Shares owned both as of the date on which Purchaser commenced the Offer, within the meaning of Rule 14d-2 under the Exchange Act and immediately prior to the Effective Time by the Company (including those held in the Company’s treasury), Parent, Purchaser or any direct or indirect wholly owned subsidiary of the Company or Parent (other than Shares held on behalf of third parties), and (b) Shares irrevocably accepted for purchase pursuant to the Offer, and (ii) Shares issued and outstanding immediately prior to the Effective Time that are held by holders who are entitled to appraisal rights under Section 262 of the DGCL and have properly exercised and perfected their respective demands for appraisal of such Shares in the time and manner provided in Section 262 of the DGCL and, as of the Effective Time, have neither validly withdrawn nor lost their rights to such appraisal and payment under the DGCL), was converted into the right to receive the Offer Price in cash (the “Merger Consideration”), without interest, subject to any withholding tax.
 
In addition, pursuant to the Merger Agreement, at the Effective Time:


each option to purchase Shares (each, a “Company Option”) that was outstanding and unexercised, whether or not vested, and which had a per Share exercise price that was less than the Merger Consideration, was canceled and converted into the right of the holder to receive (subject to any applicable withholding taxes) a lump-sum cash payment equal to (x) the excess (if any) of (a) the Merger Consideration over (b) the per Share exercise price subject to such Company Option, multiplied by (y) the total number of Shares subject to such Company Option immediately prior to the Effective Time;



each Company Option that was then outstanding and unexercised, whether or not vested, and which had a per Share exercise price that was equal to or greater than the Merger Consideration, was cancelled with no additional consideration payable therefor; and

each award of restricted stock units with respect to Shares (each, a “Company RSU”) that was outstanding, whether or not vested, was canceled and converted into the right of the holder to receive (subject to any applicable withholding taxes) a lump-sum cash payment equal to (x) the Merger Consideration, multiplied by (y) the total number of Shares subject to such Company RSU immediately prior to the Effective Time.

Following the Offer Acceptance Time, in accordance with the terms of the applicable warrant agreement and the Merger Agreement, each holder of any Company pre-funded warrant to purchase Shares (each, a “Company Prefunded Warrant”) that was outstanding and unexercised as of the Offer Acceptance Time has the right to receive, upon exercise of such Company Prefunded Warrant, the Merger Consideration with respect to each Share issuable upon exercise in full thereof, without regard to any limitations on exercise contained in the applicable warrant agreement.
 
The aggregate amount of funds used by Parent to consummate the Offer and the Merger (including payments for Company Options, Company RSUs, Company Prefunded Warrants and other payments referred to in the Merger Agreement) was approximately $2.2 billion, which was funded through Parent’s cash on hand.
