Fourth Quarter and Full Year Business Highlights

Set a new record of $503 million full year revenue from specialty and advanced packaging markets.
JetStep^® X500 system order received from the first glass substrate customer, while other customers are in production with advanced integrated circuit substrate (AICS) material and qualifying next generation products with reduced dimensions for both fan-out and heterogeneous packages.
Introduced new Firefly^® G3 inspection system aimed at manufacturers supplying panel substrates to top five customers for high performance compute products that require decreasing line widths and spaces critical for yield improvement.

Michael Plisinski, chief executive officer of Onto Innovation, commented, "Onto Innovation finished the year strongly, as we supported a surge in demand for Dragonfly systems as well as delivered several metrology systems for potential new applications in the AI packaging space. This underscores our strategy to support the entire value chain with a synergistic portfolio of process control solutions."

Plisinski continued, "In addition to packaging, revenue for our portfolio of solutions for power semiconductor customers expanded by 40% as compared to the prior year. Though our advanced nodes business saw decline matching reduced spending from our customers, we expanded our value to customers by qualifying and delivering several films and integrated metrology systems for our advanced nodes customers. As spending returns and we continue to focus on being a stronger supplier to our customers, we are optimistic that we will see additional growth. As we look ahead to 2024, we will continue to focus our resources and strengths on customer products and applications that are rapidly growing to help them develop and ramp some of the most complex manufacturing processes in the world."

Discussion of Non-GAAP Financial Measures

The Company has provided in this release non-GAAP financial measures, including non-GAAP operating income, non-GAAP net income, non-GAAP diluted earnings per share and non-GAAP operating margin, which exclude amortization of acquisition-related intangible assets, certain merger or acquisition-related expenses and benefits, significant litigation charges or benefits and legal costs, and restructuring charges. Non-GAAP operating income, non-GAAP net income, non-GAAP diluted earnings per share and non-GAAP operating margin can also exclude certain other gains and losses that are isolated or cannot be expected to occur again with any predictability or otherwise are not representative of our ongoing operations, tax provisions/benefits related to the previous items, and significant discrete tax events. We exclude the above items because they are outside of our normal operations and/or, in certain cases, are difficult to forecast accurately for future periods.

We utilize several different financial measures, both GAAP and non-GAAP, in analyzing and assessing the overall performance of our business, in making operating decisions, forecasting and planning for future periods, and determining payments under compensation programs. We consider the use of the non-GAAP measures to be helpful in assessing the performance of the ongoing operation of our business. We believe that disclosing non-GAAP financial measures provides useful supplemental data that, while not a substitute for financial measures prepared in accordance with GAAP, allows for greater transparency in the review of our financial and operational performance. We also believe that disclosing non-GAAP financial measures provides useful information to investors and others in understanding and evaluating our operating results and future prospects in the same manner as management and in comparing financial results across accounting periods and to those of peer companies. More specifically, management adjusts for the excluded items for the following reasons:

Amortization of acquisition-related intangible assets: we do not acquire businesses and assets on a predictable cycle. The amount of purchase price allocated to the purchased intangible assets and the term of amortization can vary significantly and are unique to each acquisition or purchase. We believe that excluding amortization of acquisition-related intangible assets allows the users of our financial statements to better review and understand the historic and current results of our operations, and also facilitates comparisons to peer companies.

Merger or acquisition related expenses and benefits: we incur expenses or benefits with respect to certain items associated with our mergers and acquisitions, such as transaction and integration costs, change in control payments, adjustments to the fair value of assets, etc. We exclude such expenses or benefits as they are related to acquisitions and have no direct correlation to the operation of our on-going business.

Restructuring charges: we incur restructuring and impairment charges on individual or groups of employed assets, which arise from unforeseen circumstances and/or often occur outside of the ordinary course of our on-going business. Although these events are reflected in our GAAP financials, these unique transactions may limit the comparability of our on-going operations with prior and future periods.

Significant litigation charges or benefits and legal costs: we may incur charges or benefits as well as legal costs in connection with litigation and other contingencies unrelated to our core operations. We exclude these charges or benefits, when significant, as well as legal costs associated with significant legal matters, because we do not believe they are reflective of on-going business and operating results.

Income tax expense: we estimate the tax effect of the items identified to determine a non-GAAP annual effective tax rate applied to the pretax amount in order to calculate the non-GAAP provision for income taxes. We also adjust for items for which the nature and/or tax jurisdiction requires the application of a specific tax rate or treatment.

From time to time in the future, there may be other items excluded if we believe that doing so is consistent with the goal of providing useful information to investors and management.

There are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with generally accepted accounting principles and may be different from non-GAAP financial measures used by other companies. The non-GAAP financial measures are limited in value because they exclude certain items that may have a material impact on our reported financial results. The presentation of this additional information is not meant to be considered in isolation or as a substitute for the directly comparable financial measures prepared in accordance with GAAP in the United States. Investors should review the reconciliation of the non-GAAP financial measures to their most directly comparable GAAP financial measures as provided in the tables accompanying this press release.
