Management Comments
“We delivered our fourth consecutive quarter of double-digit year-over-year revenue growth, with revenue above the midpoint of our guidance,” said Dr. Mark Gitin, Chief Executive Officer of IPG Photonics. “Our performance reflects the strength of our technology, disciplined execution, and continued progress in expanding our presence in attractive, higher-growth markets. Strong demand for our differentiated welding and additive manufacturing solutions drove growth in Industrial Solutions while disciplined execution of our key strategic initiatives across defense and semiconductor markets led to strong growth in Advanced Solutions. Additionally, I anticipate that our acquisition of Lumibird Medical, which is expected to close in the fourth quarter, will further strengthen our reach, accelerate growth across medical markets, and increase revenue in Advanced Solutions.”

Exhibit 99.1
Third quarter revenue of $288 million increased 15% year over year, driven by 12% growth in Industrial Solutions and 33% growth in Advanced Solutions. Changes in foreign exchange rates increased revenue by approximately 1%. Industrial Solutions sales, accounting for 83% of total revenue, were driven by strong performance in welding and additive manufacturing applications. Advanced Solutions sales improved, driven by higher sales in semiconductor and defense applications. Emerging growth products accounted for 52% of total revenue, down from 58% in the prior quarter due to product mix. By region, sales increased 14% in Asia and 33% in North America and decreased 1% in Europe on a year-over-year basis.
GAAP gross margin of 40.7% and adjusted gross margin of 41.0% increased year over year, driven by lower product costs and $5.0 million in net tariff refunds recorded in the period, partially offset by lower fixed cost absorption. Net income was $20 million, or $0.47 per diluted share, and adjusted EBITDA was $52 million and adjusted earnings per diluted share (EPS) was $0.61 in the third quarter. During the third quarter, IPG generated $46 million in cash flow from operations and spent $17 million on capital expenditures.
Business Outlook and Financial Guidance
“Our third quarter book-to-bill was approximately one as we continued to see improved industrial demand and executed on our strategic growth initiatives, driving adoption for our differentiated laser and photonics solutions that deliver measurable value to customers. As we move forward, we remain focused on driving profitable growth through innovation, technology differentiation, and operational excellence across our portfolio,” concluded Dr. Gitin.
For the fourth quarter of 2026, IPG expects revenue of $265 million to $295 million, adjusted gross margin between 37.0% and 40.0% and adjusted operating expenses of $91 million to $94 million. IPG anticipates delivering adjusted earnings per diluted share in the range of $0.30 to $0.60 and adjusted EBITDA in the range of $33 million to $50 million. The guidance assumes no contribution from the acquisition of Lumibird Medical.
As discussed in more detail in the "Safe Harbor" passage of this news release, actual results may differ from this guidance due to various factors including, but not limited to, trade policy changes and trade restrictions, product demand, order cancellations and delays, competition, tariffs and retaliatory tariffs, currency fluctuations and general economic conditions. The current uncertainty related to the trade environment and tariff policies increases the risks to the outlook that we have provided. This guidance is based upon current market conditions and expectations and is subject to the risks outlined in the Company's reports filed with the SEC and assumes exchange rates relative to the U.S. dollar of euro 0.88, Japanese yen 157 and Chinese yuan 6.74, respectively.

SUPPLEMENTAL SCHEDULE OF NON-GAAP FINANCIAL MEASURES (UNAUDITED)

Use of Non-GAAP Adjusted Financial Information
We refer to certain financial measures that are not recognized under United States generally accepted accounting principles (“GAAP”) and are provided as supplemental information to enhance understanding of the Company’s financial performance. Such non-GAAP financial measures should not be considered superior to, as a substitute for or alternative to, and should be considered in conjunction with, the GAAP financial measure presented by the Company. The following information provides the definition of adjusted gross profit, adjusted gross margin, adjusted operating expense and resultant adjusted operating income, EBITDA, adjusted EBITDA, adjusted net income, adjusted net earnings per share (EPS), and adjusted tax rate as presented, which are financial measures that are not calculated or presented in accordance with GAAP, and reconciliation to the most directly comparable financial measures calculated and presented in accordance with GAAP. The Company has provided adjusted gross profit, adjusted gross margin, adjusted operating expense and resultant adjusted operating income, EBITDA, adjusted EBITDA, adjusted net income, adjusted EPS, and an adjusted tax rate as supplemental information and in addition to the financial measures presented by the Company that are calculated and presented in accordance with GAAP.

We define adjusted gross profit as reported gross profit, adjusted for non-recurring, infrequent, or unusual charges, including acquisition and integration charges and amortization of acquisition-related intangibles.

We define adjusted gross margin as adjusted gross profit divided by total revenue.

We define adjusted operating expense and resultant adjusted operating income as reported operating expenses and resultant operating income, adjusted for non-recurring, infrequent, or unusual charges, including impairment charges, settlement and fees of litigation matters, restructuring charges, acquisition and integration charges, amortization of acquisition-related intangibles, foreign exchange gains/losses and gain/loss on disposal of assets/divestiture.

We define EBITDA as net income plus interest expense (income), provision for income taxes, depreciation expense, and amortization expense.

We define adjusted EBITDA as EBITDA adjusted for non-recurring, infrequent, or unusual charges, and other adjustments that the Company believes appropriate, including stock-based compensation, restructuring charges, impairment charges, settlement and fees of litigation matters, acquisition and integration charges, foreign exchange gains/losses and gain/loss on disposal of assets/divestiture.

We define adjusted net income as reported net income, adjusted for non-recurring, infrequent, or unusual charges, and other adjustments that the Company believes appropriate, including impairment charges, settlement and fees of litigation matters, restructuring charges, amortization of acquisition-related intangibles, acquisition and integration charges, foreign exchange gains/losses and gain/loss on disposal of assets/divestiture, certain discrete tax items and non-GAAP income tax reconciling adjustments.

We define adjusted EPS as adjusted net income divided by the weighted-average diluted shares outstanding.

We define adjusted tax rate as the GAAP tax rate, adjusted for discrete tax items and the net impact of non-GAAP adjustments.
Management believes that these non-GAAP financial measures provide additional means of evaluating period-over-period operating performance. Specifically, these non-GAAP financial measures provide management with additional means to understand and evaluate the operating results and trends in our ongoing business by eliminating certain non-cash expenses and other items that management believes might otherwise make comparisons of our ongoing business with prior periods more difficult, obscure trends in ongoing operations, or reduce management’s ability to make useful forecasts.

In addition, management understands that some investors and financial analysts find this information helpful in analyzing our financial and operational performance and comparing this performance to our peers and competitors. However, these non-GAAP financial measures have limitations as an analytical tool and are not intended to be an alternative to financial measures prepared in accordance with GAAP. In addition, it should be noted that these non-GAAP financial measures may be different from non-GAAP measures used by other companies. Management may, however, utilize other measures to illustrate performance in the future. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures. A reconciliation of our non-GAAP financial measures to their most directly comparable GAAP measures has been provided below. These non-GAAP measures exclude (i) amortization of acquisition-related intangibles, (ii) restructuring charges, (iii) acquisition and integration costs, (iv) impairment charges, (v) foreign

exchange gains/losses, (vi) interest income, (vii) benefit (provision) from income taxes, (viii) depreciation, (ix) amortization, (x) stock-based compensation, (xi) gain/loss on disposal of assets/divestiture, (xii) settlement and fees of litigation matters, (xiii) certain discrete tax items, and (xiv) non-GAAP income tax reconciling adjustments.

We have not provided a quantitative reconciliation of forward-looking Non-GAAP adjusted earnings per diluted share and adjusted EBITDA to their most directly comparable GAAP financial measures because we are unable to estimate with reasonable certainty the ultimate timing or amount of certain significant items without unreasonable efforts. This is due to the inherent difficulty of forecasting the timing and/or amount of various items that would impact adjusted earnings per diluted share and adjusted EBITDA. This includes items that have not yet occurred, are out of the Company’s control, cannot be reasonably predicted and/or for which there would not be any meaningful adjustment or difference. For the same reasons, the Company is unable to address the probable significance of the unavailable information.

Our non-GAAP tax provision for the fiscal third quarter of 2026 is 23%. The difference between our GAAP income tax provision and our non-GAAP income tax provision is presented as non-GAAP income tax reconciling adjustments.
