| Amendment Description | This Current Report on Form 8-K/A (this “Amendment”) is being filed as an amendment to the Current Report on Form 8-K filed by Proto Labs, Inc. (the “Company”) with the Securities and Exchange Commission (“SEC”) on February 6, 2026 (the “Original Report”). The sole purpose for filing this Amendment is to correct a scrivener’s error in reporting the guidance range for GAAP diluted earnings per share (“EPS”) for the first quarter of 2026 as described in the press release furnished as Exhibit 99.1 to the Original Report (the “Original Exhibit 99.1”). The correct GAAP diluted EPS guidance range for Q1 2026 is $0.18 to $0.26, rather than the guidance range of $0.17 to $0.25 as reported in the Original Exhibit 99.1 (the “Specified Error”). This Amendment supplements the Original Report and should be read in conjunction with the Original Report. No other changes have been made to the Original Report or Original Exhibit 99.1 other than to correct the Specified Error, as described above and reflected below. |
