Amendment Description	Markforged Holding Corporation (“we,” “us,” “our,” or the “Company”) is filing this Amendment No. 1 on Form 10-K/A (“Form 10-K/A”) to amend the Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (“2024 Form 10-K”), filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 28, 2025, to include the information required by Items 10 through 14 of Part III of Form 10-K. This information was previously omitted from the 2024 Form 10-K in reliance on General Instruction G(3) to Form 10-K. This Form 10-K/A amends and restates in their entirety Items 10, 11, 12, 13 and 14 of Part III of the 2024 Form 10-K. In addition, as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), certifications by the Company’s principal executive officer and principal financial officer are filed as exhibits to this Form 10-K/A under Item 15 of Part IV hereof. Because no financial statements have been included in this Form 10-K/A and this Form 10-K/A does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. We are not including the certifications under Section 906 of the Sarbanes-Oxley Act of 2002 as no financial statements are being filed with this Form 10-K/A. Except as described above, this Form 10-K/A does not modify or update disclosure in, or exhibits to, the 2024 Form 10-K. Furthermore, this Form 10-K/A does not change any previously reported financial results, nor does it reflect events occurring after the date of the 2024 Form 10-K. Information not affected by this Form 10-K/A remains unchanged and reflects the disclosures made at the time the 2024 Form 10-K was filed. Accordingly, this Form 10-K/A should be read in conjunction with the 2024 Form 10-K and our other filings with the SEC. On April 25, 2025, pursuant to the Agreement and Plan of Merger, dated as of September 25, 2024, by and among the Company, Nano Dimension Ltd. (“Nano”), and Nano US II, Inc., a Delaware corporation and an indirect, wholly owned subsidiary of Nano (“Merger Sub”), Merger Sub merged with and into the Company (the “Merger”), with the Company surviving the Merger as an indirect, wholly owned subsidiary of Nano. At the effective time of the Merger, the Company's directors and officers resigned from their positions as directors and officers of the Company and were replaced by the directors and officers of Merger Sub. The information set forth in the Form 10-K/A pertains to the Company's directors and officers prior to the consummation of the Merger.
