            This Amendment No. 19 (this “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO (as amended and together with any subsequent amendments and supplements thereto, the “Schedule
                TO”), filed with the U.S. Securities and Exchange Commission on October 31, 2023, by Thermo Fisher Scientific Inc., a Delaware corporation (“Parent”). The Schedule TO relates to the tender offer (the “Offer”) by Orion
              Acquisition AB, a private limited liability company organized under the laws of Sweden (“Buyer”), a direct, wholly owned subsidiary of Parent, to purchase all of the outstanding common shares, quota value SEK 2.431906612623020 per
              share (the “Shares”), and all of the outstanding American Depositary Shares, each representing one Share (the “ADSs” and together with the Shares, the “Offer Securities”), of Olink Holding AB (publ), Reg. No. 559189-7755,
              a public limited liability company organized under the laws of Sweden (“Olink”), in exchange for $26.00 per Share (that is not represented by an ADS) or $26.00 per ADS, as applicable, in cash, without interest (such amount per Share
              and ADS paid pursuant to the Offer in accordance with the Purchase Agreement (as defined in the Schedule TO)), and upon the terms and subject to the conditions set forth in the Offer to Purchase, dated as of October 31, 2023 (together with
              any amendments and supplements thereto, the “Offer to Purchase”), the related ADS Letter of Transmittal (together with any amendments and supplements thereto, the “ADS Letter of Transmittal”) and the related Acceptance Form for
              Shares (including any instruction letter attached thereto and together with any amendments and supplements thereto, the “Acceptance Form for Shares”), copies of each of which are attached to the Schedule TO as exhibits (a)(1)(A),
              (a)(1)(B) and (a)(1)(C), respectively.
            
            
            Except to the extent specifically provided in this Amendment, the information set forth in the Schedule TO remains unchanged. This Amendment is being filed to reflect certain updates as
              reflected below.
            
            
            Items 1 through 9 and Item 11.
            
            
            The Offer to Purchase and Items 1 through 9 and Item 11 of the Schedule TO, to the extent such Items incorporate by reference the information contained in the Offer to Purchase, are hereby amended and
              supplemented to include the following:
            
            
            “The Offer and withdrawal rights expired as scheduled at 5:00 p.m., New York time, on July 9, 2024 (the “Expiration Time”). The Share Tender Agent has advised Buyer that, as of the Expiration Time, 84,755,626
              Shares were validly tendered and not properly withdrawn pursuant to the Offer. The ADS Tender Agent has advised Buyer that, as of the Expiration Time, 37,676,600 ADSs were validly tendered and not properly withdrawn pursuant to the Offer.
              These Shares and ADSs collectively represent approximately 98.2% of the outstanding Shares. As a result, the Minimum Tender Condition was satisfied as of the Expiration Time. As the Minimum Tender Condition and each of the other Offer
              Conditions have been satisfied, on July 10, 2024, Buyer accepted for payment all Offer Securities that were validly tendered and not properly withdrawn pursuant to the Offer.
            
            
            In accordance with Rule 14d-11 promulgated under the Exchange Act, Buyer has commenced a subsequent offering period of the Offer (the “Subsequent Offering Period”). The Subsequent Offering Period will
              expire at 5:00 p.m., New York time, on July 16, 2024, unless extended. All Offer Securities validly tendered during the Subsequent Offering Period will be immediately accepted for payment, and tendering holders will thereafter promptly be
              paid the same Offer Price of $26.00 per Share, in cash, without interest and less applicable withholding taxes and other taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase. The procedures for accepting the
              Offer and tendering Offer Securities during the Subsequent Offering Period are the same as those applicable to the Offer as described in the Offer to Purchase, except that Shares and ADSs validly tendered during the Subsequent Offering Period
              may not be withdrawn.
            
            
            Olink has requested that the NASDAQ Global Market (“Nasdaq”) suspend trading of Olink ADSs and file a Form 25, Notification of Removal from Listing and/or Registration with the SEC, thereby commencing the
              process of delisting and deregistering the ADSs. Provided that the criteria for deregistration are met, Olink also intends to terminate its reporting obligations under the Securities Exchange Act of 1934, as amended, by filing a Certification
              and Notice of Termination of Registration on Form 15 with the SEC. Following delisting from Nasdaq, ADSs of Olink will not be listed or registered on another national securities exchange. Delisting is likely to reduce significantly the
              liquidity and marketability of any ADSs of Olink that have not been tendered pursuant to the Offer or the Subsequent Offer.
            
            
            On July 10, 2024, Parent issued a press release announcing the expiration, results and consummation of the Offer. The press release also announced the Subsequent Offering Period and Thermo Fisher’s intention to
              initiate compulsory redemption proceedings and is attached as Exhibit (a)(5)(W) hereto and incorporated herein by reference.”
           
          
          
          
          
          
          
            Item 12. Exhibits.
             
            Item 12 of the Schedule TO is hereby amended and supplemented by adding the following exhibit:
