FREMONT, Calif., November 3, 2025–Ichor Holdings, Ltd. (NASDAQ: ICHR), a leader in the design, engineering, and manufacturing of critical fluid delivery subsystems and components for semiconductor capital equipment, today announced third quarter 2025 financial results.

Third quarter 2025 highlights:

•Revenue of $239.3 million, above the mid-point of our guidance range communicated in August;

•Gross margin of 4.6% on a GAAP basis and 12.1% on a non‑GAAP basis; and

•Earnings (loss) per share of $(0.67) on a GAAP basis and $0.07 on a non-GAAP basis.

“The customer demand environment for etch and deposition strengthened during the third quarter, resulting in an acceleration of gas panel integration deliveries and total revenues at the upper end of our expectations,” commented Jeff Andreson, Ichor’s CEO. “At the same time, we witnessed further softening within our other served markets, which again pressured our ability to achieve our gross margin and profitability expectations for the quarter. Year-to-date revenues of $724 million demonstrate 18% growth year-over-year, reflecting strong performance compared to overall wafer fab equipment (WFE) growth. With our current visibility, and given the pull-in of demand witnessed among our primary etch and deposition customers during Q3, we expect Q4 revenues to track somewhat lower before regaining momentum as we move into 2026. With the robust demand environment for etch and deposition expected to continue, we look forward to a recovery in our other served markets, which we expect will provide the revenue volume momentum and gross margin tailwinds that will enable a return to our historical record of delivering strong earnings leverage.”

For the third quarter of 2025, revenue was $239.3 million, net loss was $(22.9) million, and net loss per diluted share (“diluted EPS”) was $(0.67). This compares to revenue of $240.3 million and $211.1 million, net loss of $(9.4) million and $(2.8) million, and diluted EPS of $(0.28) and $(0.08), for the second quarter of 2025 and third quarter of 2024, respectively.

For the third quarter of 2025, non-GAAP net income was $2.3 million and non-GAAP diluted EPS was $0.07. This compares to non-GAAP net income of $1.1 million and $4.0 million, and non-GAAP diluted EPS of $0.03 and $0.12, for the second quarter of 2025 and third quarter of 2024, respectively.

For the fourth quarter of 2025, we expect the following:

This outlook for non‑GAAP diluted EPS excludes amortization of intangible assets of approximately $2.1 million and share-based compensation expense of approximately $4.4 million, as well as the related income tax effects. Non-GAAP diluted EPS should be considered in addition to, but not as a substitute for, our financial information presented in accordance with GAAP.

We ended the third quarter of 2025 with cash and cash equivalents of $92.5 million, an increase of $0.3 million from the prior quarter and a decrease of $16.2 million from the prior year ended December 27, 2024.

The increase of $0.3 million in the third quarter of 2025 was primarily due to net cash provided by operating activities of $9.2 million, partially offset by capital expenditures of $7.1 million, payments for debt issuance and modification costs of $1.2 million, and net payments on our credit facilities of $0.6 million. The decrease of $16.2 million during the nine months ended September 26, 2025 was primarily due to capital expenditures of $32.9 million, net payments on our credit facilities of $4.4 million, and payments for debt issuance and modification costs of $1.2 million, partially offset by cash provided by operating activities of $20.7 million and net cash receipts related to share-based compensation of $1.6 million.

Our cash provided by operating activities of $9.2 million for the third quarter of 2025 consisted of net non-cash charges of $30.4 million, consisting primarily of inventory impairment of $16.7 million, depreciation and amortization of $7.4 million, share-based compensation expense of $4.2 million, and a decrease in our net operating assets and liabilities of $1.7 million, partially offset by a net loss of $22.9 million. Our cash provided by operating activities of $20.7 million for the nine months ended September 26, 2025 consisted of net non-cash charges of $57.6 million, consisting primarily of depreciation and amortization of $23.5 million, inventory impairment of $16.7 million, and share-based compensation expense of $12.6 million, partially offset by a net loss of $36.8 million.

The decrease in our net operating assets and liabilities of $1.7 million during the third quarter of 2025 was primarily due to a decrease in prepaid expenses and other assets of $2.8 million and an increase in accounts payable of $2.3 million, partially offset by an increase in accounts receivable of $3.6 million.

The increase in our net operating assets and liabilities of $0.1 million for the nine months ended September 26, 2025 was primarily due to an increase in inventory of $8.3 million and a decrease in other liabilities of $6.2 million, partially offset by a decrease in prepaid expenses and other assets of $7.6 million, an increase in accrued liabilities of $2.8 million, and decrease in accounts receivable of $2.2 million.

In addition to U.S. GAAP ("GAAP") results, this press release also contains non-GAAP financial results, including non‑GAAP gross profit, non‑GAAP operating income, non‑GAAP net income (loss), non‑GAAP diluted EPS, and free cash flow. Management uses non-GAAP metrics to evaluate our operating and financial results. We believe the presentation of non-GAAP results is useful to investors for analyzing business trends and comparing performance to prior periods, along with enhancing investors’ ability to view our results from management’s perspective. Non-GAAP gross profit, operating income, and net income are defined as: gross profit, operating income (loss), or net income (loss), respectively, excluding (1) amortization of intangible assets, share-based compensation expense, and discrete or infrequent charges and gains that are outside of normal business operations, including transaction-related costs, contract and legal settlement gains and losses, facility shutdown costs, inventory impairment charges, and severance costs associated with reduction-in-force programs, to the extent they are present in gross profit, operating income (loss), and net income (loss), respectively; and (2) the tax impacts associated with these non-GAAP adjustments, as well as non-recurring discrete tax items, including the impact of deferred tax asset valuation allowances. All non-GAAP adjustments are presented on a gross basis; the related income tax effects, including current and deferred income tax expense, are included in the adjustment line under the heading "Tax adjustments related to non-GAAP adjustments." Non-GAAP diluted EPS is defined as non-GAAP net income divided by weighted average diluted ordinary shares outstanding during the period. Non-GAAP gross margin and non-GAAP operating margin are defined as non-GAAP gross profit and non-GAAP operating income, respectively, divided by net sales. Free cash flow is defined as cash provided by or used in operating activities, less capital expenditures. Tables showing these metrics on a GAAP and non-GAAP basis, with reconciliation footnotes thereto, are included at the end of this press release.

Non-GAAP results have limitations as analytical tools, and you should not consider them in isolation or as substitutes for our results reported under GAAP. Other companies may calculate non-GAAP results differently or may use other measures to evaluate their performance, both of which could reduce the usefulness of our non-GAAP results as tools for comparison.

Because of these limitations, you should consider non-GAAP results alongside other financial performance measures and results presented in accordance with GAAP. In addition, in evaluating non-GAAP results, you should be aware that in the future we will incur expenses such as those that are the subject of adjustments in deriving non-GAAP results, and you should not infer from our presentation of non-GAAP results that our future results will not be affected by these expenses or other discrete or infrequent charges and gains that are outside of normal business operations.
