PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

(the “Company”) is not, without unreasonable effort and expense, able to file its Quarterly Report on Form 10-Q for the quarter ended December 31, 2022 (the “Form 10-Q”) within the prescribed time period due to a delay in completion of the financial statements for the quarter ended December 31, 2022. The delay in the issuance of the Company’s financial statements is attributable to the Company reevaluating the Company’s treatment of an epiwafer WIP sub-assembly inventory-related adjustment.

The Company expects to file the Form 10-Q within the extension period provided by Rule 12b-25.

Disclosure Regarding Forward-Looking Statements

This Notification of Late Filing on Form 12b-25 contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Words such as “expect,” and “will,” and variations of such words and similar future or conditional expressions are intended to identify forward-looking statements. These forward-looking statements include, but are not limited to, statements regarding our expectations regarding the timing of the completion of the Company’s financial statements and the filing of the Form 10-Q, which reflect the Company’s expectations based upon currently available information and data. Because such statements are based on the Company’s current expectations and are not statements of fact, actual results may differ materially from those projected or estimated and you are cautioned not to place undue reliance on these forward-looking statements. These forward-looking statements are not guarantees of future performance, conditions or results, and involve a number of known and unknown risks, uncertainties, assumptions and other important factors, many of which are outside the Company's control, that could cause actual results or outcomes to differ materially from those discussed in the forward-



looking statements. The Company disclaims and does not undertake any obligation to update or revise any forward-looking statement in this report, except as required by applicable law or regulation.
