           File No. 001-36861
Dear Wajid Ali:

       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 10-K for the Fiscal Year Ended June 28, 2025
Management's Discussion and Analysis of Financial Condition and Results of
Operations
Critical Accounting Policies and Estimates
Income Taxes, page 47

1.     We note the release of your income tax valuation allowance related to UK
deferred
       tax assets resulted in you recording an income tax benefit of $153.1
million in the
       fiscal year ended June 28, 2025. Please explain to us, and expand your
disclosures in
       future filings to more fully address, the specific positive and negative
evidence you
       considered in determining it was more-likely-than-not UK deferred tax
assets are
       realizable, how that evidence was weighed, and how that evidence led you
to
       determine it was appropriate to reverse a portion of your income tax
valuation
       allowance in the current fiscal year. Refer to Item 303(b)(3) of
Regulation S-K and
       ASC 740-10-30-16 through 30-25.

Consolidated Financial Statements
Consolidated Statements of Cash Flows, page 65

2.     Please explain to us where the reversal of the income tax valuation
allowance is
       presented in your statement of cash flows for the year ended June 28,
2025. To the
       extent it is included in income taxes, net (i.e., within changes in
operating assets and
       liabilities), revise future filings to disaggregate and separately
present the reversal of
       the income tax valuation allowance as a non-cash adjustment to reconcile
net income
       (loss) to net cash provided by operating activities. Otherwise, tell us
why the current
       presentation is appropriate, refer to ASC 230-10-45-28.
Notes to Consolidated Financial Statements
Note 17. Operating Segments and Geographic Information, page 116

3.     We note your segment disclosures state you do not track all your
property, plant, and
       equipment, by segment. Please tell us, and revise future filings to
clarify, whether any
       asset information by segment is reviewed by or provided to your CODM. If
asset
       information by segment is not provided to your CODM, clarify that fact
and explain
       the reason why as required by ASC 280-10-50-26. Specifically address why
property,
       plant, and equipment, is not tracked by segment, and clarify that this
is the reason why
       depreciation expense by segment has not been disclosed as required by
ASC 280-10-
       50-22(e).
4.     We note references to various products/product lines for each reportable
segment
       under Item 1. Business (see page 2) and within your Earnings Calls.
Please revise
       future filings to provide revenue for each product and service or each
group of similar
       products and services, as required by ASC 280-10-50-40. We note
entity-wide
       disclosures are required even if that information is not used by the
CODM. If
       providing this information is impracticable, that fact should be
disclosed.
Form 8-K filed August 12, 2025
Exhibit 99.1

5.     Your disclosures under "Use of Non-GAAP Financial Measures" indicate
non-GAAP
       financial information provides additional insight into your on-going
business
       operations and results, as well as cash generation, and indicate the
information allows
       investors to understand and evaluate cash flows. We note you previously
removed
       references to cash generation and cash flows from earnings release
disclosures since
       your non-GAAP financial measures are performance measures not liquidity
measures.
       In this regard, please revise your disclosures in future filings as
appropriate and to be
       consistent with your response to comment 8 in your response letter dated
March 15,
       2024, or advise us of any subsequent changes since that response.

        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 Dale Welcome at 202-551-3865 or Anne McConnell at
202-551-3709
with any questions.

                                                          Sincerely,

                                                          Division of
Corporation Finance
