Dear John Hollister:

       We have limited our review of your filing to the financial statements
and related
disclosures and have the following comments.

       Please respond to this letter within ten business days by providing the
requested
information or advise us as soon as possible when you will respond. If you do
not believe a
comment applies to your facts and circumstances, please tell us why in your
response.

       After reviewing your response to this letter, we may have additional
comments.

Form 6-K Furnished May 7, 2024
Exhibit 99.1, page 8

1.      Considering your free cash flow measure includes proceeds from
government grants
        related to capital expenditures and your EBITDA measure includes
adjustments for share-
        based compensation and restructuring charges, please retitle the names
of these measures
        to indicate that they reflect "adjusted" free cash flow and EBITDA.
2.      We note that you present Non-IFRS EBITDA margin without presenting the
most directly
        comparable IFRS measure on an equal or comparable basis. Please revise
your disclosures
        accordingly to include a reconciliation pursuant to Item 100(a)(1)-(2)
of Regulation G.
Form 20-F for the Fiscal Year Ended December 31, 2023
Item 5. Operating and Financial Review and Prospects
A. Operating Results, page 47

Page 2

3.     Where you identify intermediate causes of changes in your operating
results, also describe
       in sufficient detail the reasons underlying the intermediate causes. As
an example,
       although you identify and quantify several factors on pages 47-48
impacting your costs of
       revenues and gross margins, you do not explain in reasonable detail the
reasons driving
       fluctuations for all factors. In addition, although you disclose on page
52 that product mix
       "is among the most important factors affecting revenue and margins," we
do not note any
       related disclosures within your gross margin discussion. Ensure you
discuss the impact of
       product mix on your margins to the extent material. See Item 303(a) of
Regulation S-K
       and SEC Release No. 33-8350.
Notes to Consolidated Financial Statements
7. Inventories, page F-19

4.     We note that you removed the inventory reserve rollforward that was
included in your
       prior year Form 20-F. Please disclose pursuant to IAS 2.36 the amount of
any inventory
       write-downs recognized as an expense and the amount of any write-down
reversals
       recognized during the periods presented.
17. Net Revenue, page F-31

5.     We note that you quantify and discuss revenues by end market, such as
smart mobile
       devices, home and industrial, and automotive, within your quarterly
earnings calls and
       presentations. Please quantify such revenues within your future filings
pursuant to IFRS
       8.32. In addition, revise your results of operations to quantify and
discuss such revenues.
       To the extent you believe such disclosure is not required or meaningful
to include in your
       Form 20-F, explain in sufficient detail why the information is relevant
to provide on
       quarterly earnings calls but not within annual reports.
       In closing, we remind you that the company and its management are
responsible for the
accuracy and adequacy of their disclosures, notwithstanding any review,
comments, action or
absence of action by the staff.

       Please contact Stephany Yang at 202-551-3167 or Andrew Blume at

any questions.
