Rhea-AI Filing Summary

IPG Photonics reported first-quarter 2026 revenue of $265.5 million, up 17% from a year earlier, led by 21% growth in Industrial Solutions. Despite higher sales, GAAP operating results swung to a loss of $7.7 million, and net income declined to $1.6 million or $0.04 per diluted share.

Non-GAAP performance was stronger: adjusted EBITDA reached $35.2 million and adjusted earnings per diluted share were $0.29. The company highlighted cost management efforts and noted tariffs and higher product costs pressured margins. Emerging growth products contributed 53% of revenue, with notable gains in welding, cutting, marking, and cleaning applications.

For the second quarter of 2026, IPG Photonics guides to revenue of $260–$290 million, adjusted gross margin of 37–40%, adjusted operating expenses of $92–$95 million, adjusted EPS of $0.25–$0.55, and adjusted EBITDA of $32–$48 million. The company also entered an agreement with TRUMPF Laser- und Systemtechnik SE to resolve and dismiss all patent litigation worldwide between the parties.

Insights

Strong top-line growth contrasts with weaker GAAP profitability, while guidance and a global patent settlement frame the near-term outlook.

IPG Photonics delivered Q1 2026 revenue of $265.5 million, a 17% year-over-year increase, supported by 21% growth in Industrial Solutions and regional growth of 14% in Asia, 27% in North America, and 4% in Europe. Emerging growth products made up 53% of revenue, indicating continued traction in newer applications.

Profitability was mixed. GAAP operating results moved to a loss of $7.7 million, influenced in part by a $13.5 million litigation settlement charge and margin pressure from tariffs and higher product costs. However, adjusted EBITDA rose to $35.2 million and adjusted operating income to $9.3 million, suggesting underlying operations remain profitable after excluding specified items.

Management guides Q2 2026 revenue to $260–$290 million with adjusted gross margin of 37–40%, adjusted operating expenses of $92–$95 million, adjusted EPS of $0.25–$0.55, and adjusted EBITDA of $32–$48 million, based on defined exchange rates. In a separate development, the company agreed with TRUMPF Laser- und Systemtechnik SE to resolve and dismiss all patent litigation worldwide, which removes ongoing legal uncertainty, though financial terms are not detailed here.

Adjusted EBITDA financial
"Adjusted EBITDA was $35.2 million and adjusted earnings per diluted share (EPS) was $0.29 in the first quarter."
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
Industrial Solutions financial
"Industrial Solutions sales accounted for 86% of total revenue and increased 21% year over year."
Advanced Solutions financial
"Advanced Solutions sales decreased 5% year over year due to lower revenue in micromachining and defense applications."
book-to-bill financial
"Our book-to-bill was once again firmly above one in the first quarter, reflecting robust demand for our solutions."
The book-to-bill ratio compares new orders a company has received (bookings) to the products or services it has invoiced or shipped (billings) over the same period. It matters to investors because a ratio above 1 means demand is outpacing fulfillment and the company may grow revenue or build backlog, while a ratio below 1 suggests slowing demand and possible future revenue weakness — think of it as new customer orders versus what the company actually sold.
Safe Harbor Statement regulatory
"Exhibit 99.1 Safe Harbor Statement Information and statements provided by IPG and its employees, including statements in this press release, that relate to future plans, events or performance are forward-looking statements."
A safe harbor statement is a disclaimer that companies include in their public disclosures to limit legal liability if future results differ from what was forecasted or expected. It acts like a protective shield, helping companies avoid lawsuits if their predictions don’t come true, and gives investors a clearer understanding that certain statements are forward-looking and involve risks.
non-GAAP financial measures financial
"We refer to certain financial measures that are not recognized under United States generally accepted accounting principles (“GAAP”) and are provided as supplemental information."
Non-GAAP financial measures are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.
Revenue $265.5 million +17% year over year
Net income $1.6 million -58% year over year
Diluted EPS $0.04 -56% year over year
Adjusted EBITDA $35.2 million +8% year over year
Adjusted EPS $0.29 -6% year over year

Management Comments
“I am pleased to share that first-quarter revenue came in above our expectations. The team delivered our second consecutive quarter of double-digit year-over-year revenue growth, driven by disciplined execution of our key strategic initiatives and continued strong demand for our laser solutions,” said Dr. Mark Gitin, Chief Executive Officer of IPG Photonics.
Financial Highlights
Beginning in the first quarter, the Company revised its revenue disaggregation by application into two categories: Industrial Solutions and Advanced Solutions. This structure better reflects the Company's strategic growth initiatives and provides a clearer separation between the Company's industrial and non-industrial businesses, giving better visibility into the distinct performance and growth profiles of each.

Exhibit 99.1
First quarter revenue of $265 million increased 17% year over year, driven by growth in Industrial Solutions. Changes in foreign exchange rates increased revenue growth by approximately 4%. Industrial Solutions sales accounted for 86% of total revenue and increased 21% year over year, driven by growth in welding, cutting, marking, and cleaning applications. Advanced Solutions sales decreased 5% year over year due to lower revenue in micromachining and defense applications, partially offset by increased sales in medical and semiconductor applications. Emerging growth products accounted for 53% of total revenue, consistent with the prior quarter. By region, sales increased 14% in Asia, 27% in North America, and 4% in Europe on a year-over-year basis.
GAAP gross margin of 37.5% and adjusted gross margin of 37.8% decreased year over year due to tariffs and higher product cost, partially offset by lower inventory provisions. Adjusted EBITDA was $35.2 million and adjusted earnings per diluted share (EPS) was $0.29 in the first quarter. During the first quarter, IPG spent $16 million on capital expenditures.
Business Outlook and Financial Guidance
“Our book-to-bill was once again firmly above one in the first quarter, reflecting robust demand for our solutions despite elevated macroeconomic uncertainty. We remain focused on executing on our growth strategy supported by operational excellence and an innovation engine that is unlocking areas of significant additional opportunities. This foundation gives us confidence in our ability to achieve above-market growth and deliver lasting value for our customers and shareholders.” concluded Dr. Gitin.
For the second quarter of 2026, IPG expects revenue of $260 million to $290 million, adjusted gross margin between 37% and 40% and adjusted operating expenses of $92 million to $95 million. IPG anticipates delivering adjusted earnings per diluted share in the range of $0.25 to $0.55 and adjusted EBITDA in the range of $32 million to $48 million.
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 0.87, Japanese yen 159 and Chinese yuan 6.92, respectively.

Exhibit 99.1
IPG PHOTONICS CORPORATION
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. These measures should not be considered as a substitute for, or superior to, GAAP financial measures. The following information provides the definition of adjusted gross profit, adjusted gross margin, 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 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. 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.

We define adjusted gross profit as reported gross profit, adjusted for non-recurring, infrequent, or unusual changes, 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 income as reported income from operations, adjusted for non-recurring, infrequent, or unusual charges, including 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, 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 changes, and other adjustments that the Company believes appropriate, including 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) special inventory provisions, (ii) amortization of acquisition-related intangibles, (iii) restructuring charges, (iv) acquisition and integration costs, (v) goodwill and intangible asset impairments, (vi) long-lived asset impairments and accelerated depreciation of certain long-lived assets,

Exhibit 99.1

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 first quarter of 2026 is 30%. The difference between our GAAP income tax provision and our non-GAAP income tax provision is presented as non-GAAP income tax reconciling adjustments.
