EXPLANATORY NOTE

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 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.

Furthermore, such information shall not be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, unless specifically identified as being incorporated therein by reference.
