Appendix -- Non-GAAP Measures Reconciliation Cree excludes the following items from one or more of its non-GAAP measures when applicable: • Stock-based compensation expense. This expense consists of expenses for stock options, restricted stock, performance stock awards and employee stock purchases through its ESPP. Cree excludes stock-based compensation expenses from its non-GAAP measures because they are non-cash expenses that Cree does not believe are reflective of ongoing operating results. • Amortization or impairment of acquisition-related intangibles. Cree incurs amortization or impairment of acquisition-related intangibles in connection with acquisitions. Cree excludes these items because they arise from Cree's prior acquisitions and have no direct correlation to the ongoing operating results of Cree's business. • Factory optimization restructuring. In May 2019, the Company started a significant, multi-year factory optimization plan ("factory optimization plan") to be anchored by a state-of-the-art, automated 200mm silicon carbide fabrication facility. In September 2019, the Company announced the intent to build the new fabrication facility in Marcy, New York to complement the factory expansion underway at its U.S. campus headquarters in Durham, North Carolina. As part of the plan, the Company will incur restructuring costs associated with the movement of equipment as well as disposals on certain long-lived assets. Because these charges relate to assets which had been retired prior to the end of their estimated useful lives, Cree does not believe these costs are reflective of ongoing operating results. Similarly, Cree does not consider the realized losses on sale of assets relating to the restructuring to be reflective of ongoing operating results. • Project, transformation and transaction costs. The Company has incurred professional services fees associated with acquisitions and divestitures, as well as for internal transformation programs designed to improve its operating margins and change the manner in which business is conducted. Cree excludes these items because Cree believes they are not reflective of the ongoing operating results of Cree's business. • Factory optimization start-up costs. The Company has incurred and will incur start-up costs as part of the factory optimization plan. Cree does not believe these costs are reflective of ongoing operating results. • Non-restructuring related executive severance. The Company has incurred costs in conjunction with the termination of key executive personnel. Cree excludes these items because Cree believes they have no direct correlation to the ongoing operating results of Cree's business. • Transition service agreement costs. As a result of the sale of the Lighting Products business unit, the Company is providing certain IT services under a transition services agreement which will not be reimbursed. Cree excludes the costs of these services because Cree believes they are not reflective of the ongoing operating results of Cree's business. • Asset impairment. The Company incurred impairment charges in conjunction with the factory optimization plan. Cree excludes these items because Cree believes they are not reflective of the ongoing operating results of Cree's business. • Net changes in fair value of our Lextar investment. The Company's common stock ownership investment in Lextar Electronics Corporation is accounted for utilizing the fair value option. As such, changes in fair value are recognized in income, including fluctuations due to the exchange rate between the New Taiwan Dollar and the United States Dollar. Cree excludes the impact of these gains or losses from its non-GAAP measures because they are non-cash impacts that Cree does not believe are reflective of ongoing operating results. Additionally, Cree excludes the impact of dividends received on its Lextar investment as Cree does not believe it is reflective of ongoing operating results. • Accretion on convertible notes. In August 2018, the Company issued $575 million in convertible notes resulting in interest accretion on the convertible notes' issue costs and discount. Management considers these items as either limited in term or having no impact on the Company's cash flows, and therefore has excluded such items to facilitate a review of current operating performance and comparisons to our past operating performance. • Income tax adjustment. This amount reconciles GAAP tax expense (benefit) to a calculated non-GAAP tax expense (benefit) utilizing a non-GAAP tax rate. The non-GAAP tax rate estimates an appropriate tax rate if the listed non-GAAP items were excluded. This reconciling item adjusts non-GAAP net (loss) income to the amount it would be if the calculated non-GAAP tax rate was applied to non-GAAP (loss) income before taxes. 129 CREE CONFIDENTIAL & PROPRIETARY © 2019 Cree, Inc.
