Insights

Merck closes cash acquisition of Terns at $53.00 per share.

Merck has completed its acquisition of Terns Pharmaceuticals via a tender offer followed by a merger. The offer priced Terns common stock at $53.00 per share in cash. At expiration, 100,091,794 shares were validly tendered, about 86.36% of those outstanding, meeting the minimum condition.

After accepting tendered shares, Merck’s subsidiary merged into Terns, which now operates as a wholly owned Merck subsidiary. Terns’ common stock is being delisted from Nasdaq through a Form 25 filing, and the company plans to file Form 15 to terminate registration and suspend periodic SEC reporting.

Equity awards are being settled in cash: in-the-money options convert into a cash payment equal to the spread over the $53.00 merger price, while out-of-the-money options are cancelled without payment. RSUs convert into cash based on the same merger price. Governance has shifted fully to Merck’s appointees, with all former Terns directors and officers stepping down at closing.

tender offer financial
"Purchaser commenced a tender offer to purchase all of the outstanding shares of common stock"
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 Consideration financial
"was converted into the right to receive the Offer Price (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.
In the Money Option financial
"which had a per share exercise price that was less than the Merger Consideration (each, an “In the Money Option”)"
restricted stock unit financial
"each restricted stock unit award covering Shares (each, a “Company RSU”)"
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
Form 25 regulatory
"requested that Nasdaq file with the SEC a Notification of Removal from Listing and/or Registration on Form 25"
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
"Terns intends to file 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 in the Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) by Terns Pharmaceuticals, Inc., a Delaware corporation (“Terns”), on March 25, 2026, Terns entered into an Agreement and Plan of Merger (the “Merger Agreement”), dated as of March 24, 2026, with Merck Sharp & Dohme LLC, a New Jersey limited liability company (“Merck”), and Thailand Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Merck (“Purchaser”). Pursuant to the Merger Agreement, on April 7, 2026, Purchaser commenced a tender offer to purchase all of the outstanding shares of common stock, par value $0.0001 per share, of Terns (the “Shares”), at a price of $53.00 per Share (the “Offer Price”), net to the seller in cash, without interest and subject to any applicable withholding of taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated April 7, 2026 (as amended or supplemented from time to time, the “Offer to Purchase”) and the related Letter of Transmittal (as amended or supplemented from time to time, the “Letter of Transmittal” and, together with the Offer to Purchase, the “Offer”). The Offer was described in the Tender Offer Statement on Schedule TO (the “Schedule TO”), originally filed jointly by Merck & Co., Inc. (“Merck Parent”), Merck and Purchaser with the SEC, and the Offer to Purchase and the Letter of Transmittal were filed as Exhibits (a)(1)(i) and (a)(1)(ii) to the Schedule TO and are incorporated therein by reference.

 

Item 2.01

Completion of Acquisition or Disposition of Assets.

The information contained in the Introductory Note, Item 3.01, Item 5.01 and Item 5.03 of this Current Report on Form 8-K is incorporated by reference into this Item 2.01.

The Offer and related withdrawal rights expired as scheduled at one minute following 11:59 p.m., Eastern time, on May 4, 2026 (such date and time, the “Expiration Time”), and the Offer was not extended. According to Computershare Trust Company, N.A., the depositary for the Offer, as of the Expiration Time, 100,091,794 Shares had been validly tendered and not validly withdrawn pursuant to the Offer, representing approximately 86.36% of the then issued and outstanding Shares. As a result, as of the Expiration Time, a sufficient number of Shares were validly tendered and not validly withdrawn pursuant to the Offer such that the minimum tender condition to the Offer was satisfied. On May 5, 2026, promptly after the expiration of the Offer, Purchaser accepted all Shares validly tendered and not validly withdrawn pursuant to the Offer (the time of such acceptance, the “Offer Acceptance Time”), and payment of the Offer Price for such Shares will be made promptly in accordance with the terms of the Offer and the Merger Agreement.

Also on May 5, 2026, following the Offer Acceptance Time, Purchaser merged with and into Terns (the “Merger”) pursuant to the Merger Agreement and Section 251(h) of the Delaware General Corporation Law, without a vote of Terns’ stockholders, with Terns continuing as the surviving corporation (the “Surviving Corporation”) in the Merger and a wholly owned subsidiary of Merck.

At the effective time of the Merger (the “Effective Time”), each Share then issued and outstanding (other than Shares (a) held at the commencement of the Offer and immediately prior to the Effective Time by Terns (or held in Terns’ treasury), Merck, Purchaser or any other direct or indirect wholly owned subsidiary of Terns, Merck or Purchaser or (b) irrevocably accepted for purchase pursuant to the Offer) was converted into the right to receive the Offer Price (the “Merger Consideration”), without any interest thereon and subject to any withholding of taxes.

In addition, at the Effective Time, (a) each option to purchase Shares that was outstanding and unexercised immediately prior to the Effective Time, whether or not vested and which had a per share exercise price that was less than the Merger Consideration (each, an “In the Money Option”), was cancelled and converted into the right to receive (without interest) a cash payment equal to (i) the excess of (A) the Merger Consideration over (B) the exercise price payable per Share of such In the Money Option, multiplied by (ii) the total number of Shares subject to such In the Money Option, (b) each option to purchase Shares other than an In the Money Option that was outstanding and unexercised as of immediately prior to the Effective Time, whether or not vested, was cancelled with no consideration payable in respect thereof and (c) each restricted stock unit award covering Shares (each, a “Company RSU”) that was outstanding as of immediately prior to the Effective Time, whether or not vested, was cancelled and converted into the right to receive (without interest) a cash payment equal to the product of (i) the Merger Consideration and (ii) the number of Shares subject to such Company RSU.


The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 to the Current Report on Form 8-K filed with the SEC by Terns on March 25, 2026 and which is incorporated herein by reference.

Nasdaq is expected to file the Form 25 with the SEC on May 5, 2026 and trading of the Shares is expected to be suspended effective prior to the open of trading on May 5, 2026.

Terns intends to file a certification and notice of termination of registration on Form 15 with the SEC requesting the termination of registration of the Shares under Section 12(g) of the Exchange Act and the suspension of reporting obligations under Section 13 and 15(d) of the Exchange Act with respect to the Shares.

FAQ

What happened to Terns Pharmaceuticals (TERN) in the Merck transaction?

Terns Pharmaceuticals was acquired by Merck through a tender offer and follow-on merger. Merck paid $53.00 per share in cash, then merged its subsidiary into Terns, which is now a wholly owned Merck subsidiary and will no longer trade independently.

What price are Terns (TERN) shareholders receiving in the Merck acquisition?

Terns shareholders are receiving $53.00 in cash per common share. This price was the tender offer and merger consideration, paid net to the seller without interest but subject to tax withholding, and applies both in the tender offer and in the back-end merger conversion.

How many Terns (TERN) shares were tendered into Merck’s offer?

As of the tender offer expiration, 100,091,794 Terns shares were validly tendered and not withdrawn. This represented approximately 86.36% of Terns’ outstanding shares, which satisfied the minimum tender condition required to complete the acquisition and proceed to the merger.

What happens to Terns (TERN) stock now that Merck closed the merger?

Terns’ common stock will be delisted from the Nasdaq Global Select Market. Nasdaq is expected to file Form 25, and Terns plans to file Form 15 to terminate SEC registration, meaning TERN will cease trading and stop regular SEC reporting as a standalone company.

How are Terns (TERN) stock options and RSUs treated in the Merck deal?

In-the-money stock options are cancelled and cashed out for the spread between $53.00 and the exercise price, multiplied by shares. Out-of-the-money options are cancelled without payment. Each RSU converts into a cash payment equal to $53.00 times the number of RSU shares.

Did control of Terns Pharmaceuticals (TERN) change as part of this transaction?

Yes. A change of control occurred when Merck’s tender offer closed and the subsequent merger became effective. Terns is now a wholly owned subsidiary of Merck, with all former directors and officers replaced by Merck-appointed directors and officers of the surviving corporation.
