Fusen Chen, Kulicke & Soffa's President and Chief Executive Officer, stated, "Despite a shifting Advanced Display market, we remain nimble and efficiency focused. We are preparing for broader Ball Bonder demand recovery and have reallocated Advanced Display resources to support growing demand and activity within Thermocompression and Advanced Dispense. We look forward to achieve new customer and market adoption milestones over the coming quarters."

During its recently completed quarter, the Company's Ball Bonder revenue has grown by more than 50% over the same period in the prior fiscal year. K&S is preparing to further ramp its Ball Bonder supply chain and production activities, in support of General Semiconductor recovery, which includes fulfilling a sizeable order from a fast-growing Assembly and Test customer of 1,000 RAPID™ Pro systems, as announced earlier today.

Use of Non-GAAP Financial Results

In addition to U.S. GAAP ("GAAP") results, this press release also contains the following non-GAAP financial results: income from operations, operating margin, net income, net margin, net income per fully diluted share and adjusted free cash flow. The Company's non-GAAP results exclude amortization related to intangible assets acquired through business combinations, costs associated with restructuring and severance, equity-based compensation, acquisition and integration costs, impairment relating to assets acquired through business combinations, long-lived asset impairment relating to business cessation or disposal, impairment relating to equity investments, income tax expense/benefit arising from discrete tax items triggered by acquisition, disposal of business (both via a sale or an abandonment), restructuring and significant changes in tax laws, gain/loss on disposal of business, as well as tax benefits or expenses associated with the foregoing non-GAAP items. The non-GAAP adjustments may or may not be infrequent or nonrecurring in nature, but are a result of periodic or non-core operating activities. These non-GAAP measures are consistent with the way management analyzes and assesses the Company’s operating results. The Company believes these non-GAAP measures enhance investors’ understanding of the Company’s underlying operational performance, as well as their ability to compare the Company’s period-to-period financial results and the Company’s overall performance to that of its competitors.

Management uses both GAAP metrics as well as these non-GAAP metrics to evaluate the Company's operating and financial results. Non-GAAP financial measures may not provide information that is directly comparable to that provided by other companies in the Company’s industry, as other companies in the industry may calculate non-GAAP financial results differently. In addition, there are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with GAAP, may be different from non-GAAP financial measures used by other companies and exclude expenses that may have a material impact on the Company’s reported financial results. The presentation of non-GAAP items is meant to supplement, but not substitute for, GAAP financial measures or information. The Company believes the presentation of non-GAAP results in combination with GAAP results provides better transparency to the investment community when analyzing business trends, providing meaningful comparisons with prior period performance and enhancing investors' ability to view the Company's results from management's perspective. A reconciliation of each non-GAAP financial measure to the most directly comparable GAAP measure discussed in this press release is contained in the financial tables at the end of this press release.
