Synaptics Reports Results for Second Quarter Fiscal 2020

Business Highlights

SAN JOSE, Calif., – February 6, 2020 – Synaptics Incorporated (NASDAQ: SYNA), the leading developer of human interface solutions, today reported financial results for its second quarter ended December 28, 2019.

Net revenue for the second quarter of fiscal 2020 was up 14 percent sequentially to $388.3 million and exceeded the guidance the company provided last quarter. GAAP net income for the second quarter of fiscal 2020 was $19.8 million, or $0.58 per diluted share. Non-GAAP net income for the second quarter of fiscal 2020 increased $29.1 million sequentially to $70.1 million, or $2.04 per diluted share, a record for the company. (See below under the heading “Use of Non-GAAP Financial Information” and the attached table for a description and a reconciliation of GAAP to Non-GAAP financial measures.)

“Our December quarter was better than expected due to unusually strong demand for our PC products and from our largest mobile customer during the holiday season,” said Michael Hurlston, president and chief executive officer, Synaptics. “Early efforts to focus our resources on high margin products coupled with greater operational discipline resulted in a record quarter for Non-GAAP net income and EPS. We are making good progress in defining our long-term portfolio and in transforming Synaptics into a company with differentiated franchise businesses that can generate sustainable and profitable growth.”

Cash at December 31, 2019 was $425 million. Cash flow from operations during the second quarter of fiscal 2020 was $73 million.

Business Outlook

Dean Butler, chief financial officer of Synaptics, added, “We had a record finish to calendar 2019 and continue to maintain a healthy backlog of $284 million entering the March quarter and expect that subsequent bookings, customer forecasts and product sell-in and sell-through patterns will result in revenue for the third quarter of fiscal 2020 to be in the range of $330 to $350 million. Based upon this guidance, we expect the revenue mix from mobile, IoT and PC products to be approximately 52 percent, 24 percent and 24 percent respectively.”

For the third quarter of fiscal 2020, the company expects:

Use of Non-GAAP Financial Information

In evaluating its business, Synaptics considers and uses Non-GAAP Net Income, which we define as net income excluding share-based compensation, acquisition related costs, and certain other non-cash or recurring and non-recurring items the company does not believe are indicative of its core operating performance as a supplemental measure of operating performance. Non-GAAP Net Income is not a measurement of the company’s financial performance under GAAP and should not be considered as an alternative to GAAP net income. The company presents Non-GAAP Net Income because it considers it an important supplemental measure of its performance since it facilitates operating performance comparisons from period to period by eliminating potential differences in net income caused by the existence and timing of share-based compensation charges, acquisition related costs, and certain other non-cash or recurring and non-recurring items. Non-GAAP Net Income has limitations as an analytical tool and should not be considered in isolation or as a substitute for the company’s GAAP net income. The principal limitations of this measure are that it does not reflect the company’s actual expenses and may thus have the effect of inflating its net income and net income per share as compared to its operating results reported under GAAP. In addition, the company presents components of Non-GAAP Net Income, such as Non-GAAP Gross Margin and Non-GAAP operating expenses, for similar reasons.

As presented in the “Reconciliation of GAAP Financial Measures to Non-GAAP Financial Measures” tables that follow, Non-GAAP Net Income and each of the other Non-GAAP financial measures excludes one or more of the following items:

Acquisition/divestiture related costs.

Acquisition/divestiture related costs primarily consist of:

These acquisition/divestiture related costs are not factored into the company’s evaluation of its ongoing business operating performance or potential acquisitions, as they are not considered as part of the company’s principal operations. Further, the amount of these costs can vary significantly from period to period based on the terms of an earn-out arrangement, revisions to assumptions that went into

developing the estimate of the contingent consideration associated with an earn-out arrangement, the size and timing of an acquisition/divestiture, the lives assigned to the acquired intangible assets, and the maturity of the business acquired. Excluding acquisition/divestiture related costs from Non-GAAP measures provides investors with a basis to compare Synaptics against the performance of other companies without the variability and potential earnings volatility associated with purchase accounting and acquisition/divestiture related items.

Share-based compensation.

Share-based compensation expense relates to employee equity award programs and the vesting of the underlying awards, which includes stock options, deferred stock units, market stock units, performance stock units, phantom stock units and the employee stock purchase plan. Share-based compensation settled with stock, which includes stock options, deferred stock units, market stock units, performance stock units and the employee stock purchase plan, is a non-cash expense, while share-based compensation settled with cash, which includes phantom stock units, is a cash expense. Settlement of all employee equity award programs whether settled with cash or stock varies in amount from period to period and is dependent on market forces that are often beyond the company’s control. As a result, the company excludes share-based compensation from its internal operating forecasts and models. The company believes that Non-GAAP measures reflecting adjustments for share-based compensation provide investors with a basis to compare the company’s principal operating performance against the performance of peer companies without the variability created by share-based compensation resulting from the variety of equity-linked compensatory awards used by other companies and the varying methodologies and assumptions used.

Restructuring costs.

Restructuring costs consist primarily of employee severance and office closure costs, including the reversal of such costs. These costs are cash-based and designed to address cost structure inefficiencies. As a result, the company excludes restructuring costs from its internal operating forecasts and models when evaluating its ongoing business performance. The company believes that Non-GAAP measures reflecting adjustments for restructuring costs provide investors with a basis to compare the company’s principal operating performance against the performance of other companies without the variability created by restructuring costs designed to address cost structure inefficiencies in its business.

Retention program costs.

Retention program costs consist of employee retention arrangement costs designed to ensure operational continuity and support through employee retention. These costs are cash-based and designed to ensure retention of certain key engineering and management employees as we transition the company through senior level management and product focus changes. As a result, the company excludes retention program costs from its internal operating forecasts and models when evaluating its ongoing business performance. The company believes that Non-GAAP measures reflecting adjustments for retention program costs provide investors with a basis to compare the company’s principal operating performance

against the performance of other companies without the variability created by retention program costs designed to ensure operational continuity and support through employee retention during a transition of senior level management and product focus changes.

In-process research and development.

In-process research and development represents research and development that is not yet complete. In the context of a business combination, in-process research and development costs will be capitalized and subsequently amortized over an estimated life or impaired. In the context of an asset acquisition, in-process research and development costs will be expensed immediately unless there is an alternative future use. From time to time, we may acquire in-process research and development assets as part of an asset acquisition. If determined to have no alternative future use, these in-process research and development assets will be expensed in the period acquired. As a result, the company excludes in-process research and development costs from its internal operating forecasts and models when evaluating its ongoing business performance. The company believes that Non-GAAP measures reflecting adjustments for in-process research and development costs provide investors with a basis to compare the company’s principal operating performance against the performance of other companies without the variability created by in-process research and development costs.

Other non-cash items.

Other non-cash items includes non-cash amortization of debt discount and issuance costs. These items are excluded from Non-GAAP results as they are non-cash. Excluding other non-cash items from Non-GAAP measures provides investors with a basis to compare Synaptics against the performance of other companies without the variability associated with other non-cash items.

Recovery on sale of investment.

Recovery on sale of investment, represents the gain on the recovery of an investment in which the cost basis was previously written down to fair value. This item is excluded from Non-GAAP results as the previous write-down was excluded from Non-GAAP results. Excluding recovery on sale of investment from Non-GAAP measures provides investors with a basis to compare Synaptics against the performance of other companies without the variability associated with recovery on sale of investment.

Arbitration settlement, net

Arbitration settlement, net represents the impact of the settlement of an arbitration matter net of related legal and consulting services that is unusual or infrequent. As a result, the company excludes from its internal operating forecasts and models, when evaluating its ongoing business performance, arbitration settlement amounts net of related costs. The company believes that Non-GAAP measures reflecting an adjustment for arbitration settlements net of related costs provides investors with a basis to compare the company’s principal operating performance against the performance of other companies without the variability created by infrequent, non-recurring or non-routine arbitration settlements net of related costs.

Equity investment loss.

Equity investment loss represents an adjustment in the book value of an equity investment in a minority owned company. The equity investment loss is a non-cash item. As a result, the company excludes equity investment loss from its internal operating forecasts and models when evaluating its ongoing business performance. The company believes that Non-GAAP measures reflecting adjustments for equity investment loss provide investors with a basis to compare the company’s principal operating performance against the performance of other companies without the variability created by non-cash items.

Non-GAAP tax adjustments.

The company forecasts its long-term Non-GAAP tax rate in order to provide investors with improved long-term modeling accuracy and consistency across financial reporting periods by eliminating the effects of certain items in our Non-GAAP net income and Non-GAAP net income per share, including the type and amount of share-based compensation, the taxation of post-acquisition intercompany intellectual property cross-licensing or transfer transactions, and the impact of other acquisition items that may or may not be tax deductible. The company intends to evaluate its long-term Non-GAAP tax rate annually for significant events, including material tax law changes in the major tax jurisdictions in which the company operates, corporate organizational changes related to acquisitions or tax planning opportunities, and substantive changes in our geographic earnings mix.
