(“ElevATE”) pursuant to the Agreement and Plan of Merger, dated as of July 10, 2026 (the “Merger Agreement”), by and among the Company, ElevATE, GN Merger Sub Inc. and Presidio Investors ELV Continuation GP, LLC. Pursuant to the Merger Agreement, GN Merger Sub Inc. merged with and into ElevATE, with ElevATE surviving the merger as a wholly owned subsidiary of the Company (the “Merger”).

The Company previously disclosed the entry into the Merger Agreement under Items 1.01 and 7.01 of its Current Report on Form 8-K filed with the Securities and Exchange Commission on July 14, 2026, which disclosure is incorporated herein by reference. A copy of the Merger Agreement was filed as Exhibit 2.1 to such Current Report on Form 8-K.

ElevATE is a fabless semiconductor company based in San Diego, California that specializes in the development of highly integrated, low-power analog and mixed-signal semiconductor solutions that address the industry’s most demanding semiconductor test challenges. The acquisition expands the Company’s analog and mixed-signal product portfolio and strengthens the Company’s position in attractive, high-growth end markets driven by increasing semiconductor complexity and test intensity.
