Shareholder Meeting Form 8 K

Due to the delay in filing 3D Systems Corporation's (the "Company") Annual Report on Form 10-Kfor the fiscal year ended December 31, 2023, the Company now expects the Company's 2024 Annual Meeting of Stockholders (the "Annual Meeting") to be held on or about August 27, 2024. On June 26, 2024, the Company's Board of Directors approved July 2, 2024, as the record date for the Annual Meeting. Only stockholders of record at the close of business on that date may attend and vote at the Annual Meeting or any adjournment or postponement thereof.

Because the date of the Annual Meeting will differ by more than 30 days from the anniversary date of the Company's 2023 Annual Meeting of Stockholders, the previously announced deadline for stockholder proposals pursuant to Rule 14a-8under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), is no longer applicable. Under the new deadline set by the Company, any stockholder proposal intended to be included in the Company's proxy materials for the Annual Meeting pursuant to Exchange Act Rule 14a-8must be delivered to, or mailed to and received at, the Company's principal executive offices located at 3D Systems Corporation, 333 Three D Systems Circle, Rock Hill, South Carolina 29730, Attn: Corporate Secretary, on or before the close of business on July 8, 2024, which the Company has determined to be a reasonable time before it expects to begin to print and distribute its proxy materials for the Annual Meeting. In addition to complying with this deadline, stockholder proposals intended to be included in the Company's proxy materials for the Annual Meeting must also comply with all applicable U.S. Securities and Exchange Commission rules, including Exchange Act Rule 14a-8.

In addition, because the date of the Annual Meeting will be more than 60 days after the anniversary date of the Company's 2023 Annual Meeting of Stockholders, the previously announced deadline for stockholder proposals or nominations under Section 2.12 of the Company's Amended and Restated By-Laws(the "By-Laws")is no longer applicable. Pursuant to the By-Laws,the new deadline for any stockholder proposal or nomination (other than pursuant to Exchange Act Rule 14a-8)intended to be brought before the Annual Meeting must be delivered to, or mailed to and received at, the Company's principal executive offices located at 3D Systems Corporation, 333 Three D Systems Circle, Rock Hill, South Carolina 29730, Attn: Corporate Secretary, on or before the close of business on July 8, 2024. In addition to complying with this deadline, stockholder proposals or nominations intended to be brought before the Annual Meeting must also comply with all applicable U.S. Securities and Exchange Commission rules, the By-Lawsand applicable law.
