BLOOMINGTON, Minn., – November 5, 2025 – SkyWater Technology, Inc. (NASDAQ: SKYT), the largest exclusively U.S.-based, pure-play semiconductor foundry, today announced financial results for the third quarter 2025 ended September 28, 2025.

“We’re pleased to report financial results for the third quarter that exceeded our expectations across all metrics,” commented Thomas Sonderman, CEO. “Revenues from multiple quantum computing customers reached a new quarterly record, and we are on track to exceed 30% growth in our ATS revenues from quantum customers in fiscal 2025. We have signed four new quantum customers since the second quarter, building significant momentum as we establish SkyWater as the foundry partner of choice for this emerging growth end market. We believe our exclusively U.S. focus and Trusted status as a pure-play foundry partner make us the ideal manufacturing partner for multiple quantum computing technologies, and we expect to announce continued momentum in the coming quarters.

“Furthermore, we are very pleased to report financial results for our first full quarter of Texas operations that were significantly stronger than initially forecast. At the same time, we witnessed an acceleration of program timing within our aerospace and defense end markets, which led to stronger ATS development revenues in the quarter, compared to forecast. We believe 2025 is a transformative year for SkyWater, and anticipate continued strong growth ahead in the coming years.”

•Strong momentum in quantum computing. Four new ATS (Advanced Technology Services) engagements with quantum computing companies have been signed since the second quarter, including with named customers SQC and QuamCore. With strong sequential ATS revenue growth reported for the third quarter, we expect to exceed 30% revenue growth in quantum computing related revenues in 2025.

•Significant upside recognized in first quarter of Texas operations. Both the revenue and profitability of our newly-acquired operations in Texas (“Fab 25”) exceeded our expectations. As a result of the acquisition of Fab 25, we now operate as two distinct reportable segments, which are Legacy SkyWater and SkyWater Texas. Third quarter revenue for SkyWater Texas was higher than expected and reflects the effects of purchase accounting, which has not been finalized, as well as additional revenue generated from higher than expected wafer production levels experienced immediately post-acquisition. The upside in SkyWater Texas revenue likewise resulted in favorable gross margin and earnings performance.

•Acceleration of ATS demand into Q3. Third quarter ATS revenues came in stronger than forecast due to the timing of program execution during the quarter. Our expectations for full-year ATS development revenues remain consistent with our prior August forecast, as the U.S. Government budget approvals remain delayed.

•Advanced Packaging revenues starting to ramp in Florida. Advanced Packaging facilitization progressed well during the third quarter. Tool installations are ramping and currently scheduled for completion in early-2026, readying our Florida operations for customer prototype builds expected later next year.

(1)ATS development revenue represents GAAP revenue primarily derived from process development services, tool installation and qualification services, facility and tool access, leases where SkyWater serves as lessor, and security services.

(2)Tools revenue represents GAAP revenue primarily derived from the procurement and subsequent sale of equipment to our customers. While this equipment is owned by our customers, the equipment is retained in one of our fabs and is used to complete ATS customer programs.

•Revenue: Legacy SkyWater revenue of $64.1 million decreased 32% compared to the third quarter of 2024, and is inclusive of $54.2 million of ATS development revenue, $6.2 million of Wafer Services revenue, and $3.7 million of Tools revenue. Legacy SkyWater ATS development revenue decreased 4% compared to the third quarter of 2024. Legacy SkyWater Wafer Services revenue decreased by 7% compared to the third quarter of 2024. Legacy SkyWater Tools revenue decreased by 88% compared to the third quarter of 2024. SkyWater Texas revenue was $86.6 million and is composed of Wafer Services revenue which includes revenues recognized on the off-market component of the supply agreement recorded in the preliminary purchase accounting for Fab 25.

•Gross Profit: GAAP gross profit was $36.2 million, or 24.0% of total revenue, compared to gross profit of $20.2 million, or 21.6% of total revenue, in the third quarter of 2024. Non-GAAP gross profit was $37.1 million, or 24.6% of total revenue, compared to non-GAAP gross profit of $20.9 million, or 22.3% of total revenue, in the third quarter of 2024. Tools revenue negatively impacted non-GAAP gross margin by 70 bps, compared to 1,050 bps in the third quarter of 2024.

•Operating Expenses: GAAP operating expenses were $28.4 million, compared to $15.5 million in the third quarter of 2024. Non-GAAP operating expenses were $23.5 million, compared to $14.1 million in the third quarter of 2024.

•Net Income: GAAP net income to shareholders inclusive of a preliminary $110.8 million bargain purchase gain related to the Fab 25 acquisition was $144.0 million, or $2.95 per diluted share, compared to a net income to shareholders of $1.5 million, or $0.03 per diluted share, in the third quarter of 2024. Non-GAAP net income to shareholders was $11.5 million, or $0.24 per diluted share, compared to a non-GAAP net income to shareholders of $3.6 million, or $0.08 per diluted share, in the third quarter of 2024. GAAP net income in the third quarter of 2025 was positively impacted by income tax benefit of $31.8 million, $27.5 million of which related to the release of a tax valuation allowance and the remaining $4.3 million, equivalent to $0.09 per share, related to tax benefits realized on post-acquisition deferred tax assets realization.

•Adjusted EBITDA: Adjusted EBITDA was $25.8 million, or 17.1% of total revenue, compared to $11.0 million, or 11.7% of total revenue, in the third quarter of 2024.

A reconciliation between GAAP and non-GAAP financial measures is contained in the tables below in the section titled “Non-GAAP Financial Measures.”

Our current expectations of fourth quarter financial results reflect the following ranges:

The outlook for non‑GAAP gross margin, operating expenses, and diluted net loss per share excludes anticipated equity-based compensation expense of approximately $2.4 million, or $0.05 per share (with an estimated $1.6 million in operating expenses and the remaining $0.8 million in cost of revenue), and estimated transaction-related costs of approximately $3.8 million, or $0.08 per share (all of which is included in operating expenses). Non-GAAP diluted net loss per share should be considered in addition to, but not as a substitute for, our financial information presented in accordance with GAAP.

SkyWater will host a conference call today, Wednesday, November 5, 2025, at 3:30 p.m. CT (4:30 p.m. ET) to discuss its third quarter 2025 financial results. A live webcast of the call will be available online at IR.SkyWaterTechnology.com.

(1)ATS development revenue represents GAAP revenue primarily derived from process development services, tool installation and qualification services, facility and tool access, leases where SkyWater serves as lessor, and security services.

(2)Tools revenue and cost of tools revenue represents GAAP revenue and cost primarily derived from the procurement and subsequent sale of equipment to our customers. While this equipment is owned by our customers, the equipment is retained in one of our fabs and is used to complete ATS customer programs.

(3)SkyWater accounts for the impacts of customer contract modifications in accordance with GAAP. Customer contract modifications that add or eliminate performance obligations and thereby change the scope of our customer programs often impact the revenue and/or cost of revenue associated with performance on customer programs. In the first quarter of 2024, we recorded a $8,004 charge to recognize future estimated losses for one significant customer program based on anticipated cost increases to complete the customer’s program. In the third quarter of 2024, we successfully modified a significant customer contract, which resulted in a decrease in our estimate of future costs to complete their program. The remaining $5,616 loss accrual recorded at the time the contract was modified was released, which reduced cost of revenue for the three-month period ended September 29, 2024.

We provide non-GAAP financial information that our management regularly evaluates to provide additional insight to investors and to supplement our results reported using U.S. generally accepted accounting principles (GAAP). We provide non-GAAP cost of revenue, non-GAAP gross profit, non-GAAP gross margin, non-GAAP research and development expense, non-GAAP selling, general and administrative expense, non-GAAP net income (loss) to shareholders, non-GAAP net income (loss) to shareholders per basic share and non-GAAP net income (loss) per diluted share. Our management uses these non-GAAP financial measures to make informed operating decisions, complete strategic planning, prepare annual budgets, and evaluate Company and management performance. We believe these non-GAAP financial measures are useful performance measures to our investors because they provide a baseline for analyzing trends in our business and exclude certain items that may not be indicative of our core operating results. The non-GAAP financial measures disclosed in this earnings release should not be viewed as an alternative to, or more meaningful than, the reported results prepared in accordance with GAAP. In addition, because these non-GAAP financial measures are not determined in accordance with GAAP, other companies, including our peers, may calculate their non-GAAP financial measures differently than we do. As a result, the non-GAAP financial measures presented in this earnings release may not be directly comparable to similarly titled measures presented by other companies.

We also provide earnings before interest, income taxes, depreciation and amortization (EBITDA), adjusted EBITDA and adjusted EBITDA margin as supplemental non-GAAP measures. We define adjusted EBITDA as net income (loss) attributable to SkyWater Technology, Inc. before interest expense, income tax expense (benefit), depreciation and amortization, and certain other items that we do not view as indicative of our ongoing performance, including net income attributable to noncontrolling interests; equity-based compensation expense; management transition expense; transaction and integration costs, tax benefits from the release of tax valuation allowances, and bargain purchase gains. Our management uses EBITDA, adjusted EBITDA and adjusted EBITDA margin to make informed operating decisions, complete strategic planning, prepare annual budgets, and evaluate Company and management performance. We believe these non-GAAP financial measures are useful performance measures to our investors because they allow for an effective evaluation of our operating performance when compared to other companies, including our peers, without regard to financing methods or capital structures. We exclude the items listed above from net income (loss) in arriving at adjusted EBITDA and adjusted EBITDA margin because the amounts of these items can vary substantially within our industry depending on the accounting methods and policies used, book values of assets, capital structures, and the methods by which assets were acquired. These non-GAAP financial measures should not be considered as an alternative to, or more meaningful than, the reported results prepared in accordance with GAAP. Certain items excluded from these non-GAAP financial measures are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic cost bases of depreciable assets, none of which are reflected in these non-GAAP financial measures. Our presentation of these non-GAAP financial measures should not be construed as an indication that our results will be unaffected by the items excluded from adjusted EBITDA and adjusted EBITDA margin. In future fiscal periods, we may exclude such items and may incur income and expenses similar to these excluded items. Accordingly, the exclusion of these items, and other similar items, from these non-GAAP financial measures should not be interpreted as implying that these items are non-recurring, infrequent or unusual, unless otherwise expressly indicated.

The following tables present a reconciliation of the most directly comparable financial measures, calculated and presented in accordance with GAAP, to our non-GAAP financial measures.

(1) Represents non-cash equity-based compensation expense.

(2) Represents the tax benefit from the release of tax valuation allowances previously recorded against tax attributes recognized as deferred tax assets. SkyWater releases tax valuation allowances when facts and circumstances change and demonstrate the Company has future sources of taxable income that will allow it to realize its tax attributes.

(3) Represents the cost of severance, separation, and other termination benefits related to the reorganization of the manufacturing, sales, marketing, and operations leadership team.

(4) Represents transaction and integration costs associated with our June 30, 2025 acquisition of Fab 25, including legal fees, professional services fees, consultant fees, and other costs to effectuate the closing of the transaction and integration of the acquired business.

(5) Represents net income attributable to noncontrolling interests arising from our variable interest entity (VIE), which was formed for the purpose of purchasing the land and building of our primary operating facility in Bloomington, Minnesota. Since interest expense is added back to net loss to shareholders in our adjusted EBITDA financial measure, we also add back the net income attributable to noncontrolling interests as its net income is derived from interest the VIE charges SkyWater.

(6) Represents the preliminary bargain purchase gain recognized for the acquisition of Fab 25 on June 30, 2025. The total consideration paid by SkyWater to acquire Fab 25 was less than the fair value of the net assets acquired and necessitated the recognition of the bargain purchase gain pursuant to GAAP. The amount of the bargain purchase gain is impacted by the fair values assigned to the net assets acquired in purchase accounting. Values in this regard, as well as related tax impacts, are preliminary in nature as of the date of this release and are subject to finalization in the next several quarters as allowed by GAAP. Changes in values are to be expected and could be significant as this work is finalized. Any adjustments recognized to finalize purchase accounting will impact the amount of the bargain purchase gain arising from the acquisition and will be reflected on a prospective basis in future quarters.
