Such forward-looking statements and the associated risks and uncertainties include, among others: (i) our beliefs with respect to the length and severity of the COVID-19 (coronavirus) outbreak, and its impact across our businesses, our operations and global supply chain, including (a) the potential impact on our ability to source necessary component parts from key suppliers and volatility in prices, including risks associated with our manufacturers which could continue to negatively affect our profitability and/or market share (b) our expectations that the virus has caused and will continue to cause, an increase in customer and partner demand, including increased demand in collaboration endpoints due to a global, work from anywhere workforce, (c) expectations related to our ability to timely supply the number of products to fulfill current and future customer demand, (d) the impact of the virus on our distribution partners, resellers, end-user customers and our production facilities, including our ability to obtain alternative sources of supply if our production facility or other suppliers are impacted by future shut downs, (e) the impact if global or regional economic conditions deteriorate further, on our customers and/or partners, including increased demand for pricing accommodations, delayed payments, delayed deployment plans, insolvency or other issues which may increase credit losses, and (f) the complexity of the forecast analysis, including scenario planning and the design and operation of internal controls; and (ii) our belief that we can manufacture or supply products in a timely manner to satisfy orders; (iii) expectations related to our customers’ purchasing decisions and our ability to match product production to demand, particularly given long lead times and the difficulty of forecasting unit volumes and acquiring the component parts and materials to meet demand without having excess inventory or incurring cancellation charges; (iv) risks associated with significant and abrupt changes in product demand which increases the complexity of management’s evaluation of potential excess or obsolete inventory; (v) risks associated with the bankruptcy or financial weakness of distributors or key customers, or the bankruptcy of or reduction in capacity of our key suppliers; (vi) risks associated with the potential interruption in the supply of sole- sourced critical components, our ability to move to a dual-source model, and the continuity of component supply at costs consistent with our plans; (vii) expectations that our current cash on hand, additional cash generated from operations, together with sources of cash through our credit facility, either alone or in combination with our election to defer debt repayment until after the first quarter of fiscal year 2021 and our election to suspend our dividend payments, will meet our liquidity needs during and following the unknown duration and impact of the COVID-19 pandemic; (viii) expectations relating to our ability to generate sufficient cash flow from operations to meet our debt covenants and timely repay all principal and interest amounts drawn under our credit facility as they become due; (ix) risks associated with our channel partners’ sales reporting, product inventories and product sell through since we sell a significant amount of products to channel partners who maintain their own inventory of our products;

(xiv) risks associated with forecasting sales and procurement demands, which are inherently difficult, particularly with continuing uncertainty in regional and global economic conditions; (xv) uncertainties attributable to currency fluctuations, including fluctuations in foreign exchange rates and/or new or greater tariffs on our products; (xvi) our expectations regarding our ability to control costs, streamline operations and successfully implement our various cost-reduction activities and realize anticipated cost savings under such cost- reduction initiatives; (xvii) expectations relating to our quarterly and annual earnings guidance, particularly as economic uncertainty due to COVID-19 puts further pressure on management judgments used to develop forward looking financial guidance and other prospective financial information; (xviii) estimates of GAAP and non-GAAP financial results for the fourth quarter and full Fiscal Year 2020, including net revenues, adjusted EBITDA, tax rates, intangibles amortization, impairment analysis, diluted weighted average shares outstanding and diluted EPS; (xix) our expectations of the impact of the acquisition of Polycom as it relates to our strategic vision and additional market and strategic partnership opportunities for our combined hardware, software and services offerings; (xx) our beliefs regarding the UC&C market, market dynamics and opportunities, and customer and partner behavior as well as our position in the market, including risks associated with the potential failure of our UC&C solutions to be adopted with the breadth and speed we anticipate;

We do not assume any obligation to update or revise any such forward-looking statements, whether as the result of new developments or otherwise. For more information concerning these and other possible risks, please refer to our Annual Report on Form 10-K filed with the Securities and Exchange Commission on May 17, 2019 and other filings with the Securities and Exchange Commission, as well as recent press releases. © 2020 Plantronics Inc.

USE OF NON-GAAP INFORMATION To supplement our condensed consolidated financial statements presented on a GAAP basis, we use non-GA A P, and where applicable, combined comparative measures of operating results, including non-GAAP net revenues, non-GAAP gross profit, non-GAAP operating expenses, non-GAAP operating income, adjusted EBITDA, and non-GAAP diluted EPS. These non-GAAP measures are adjusted from the most directly comparable GAAP measures to exclude, or include where applicable, the effect of purchase accounting on deferred revenue and inventory, charges associated with the optimization of our Consumer product line, stock-based compensation, acquisition related expenses, purchase accounting amortization and adjustments, restructuring and other related charges and credits, impairment charges, rebranding costs, other unusual and/or non-cash charges and credits, and the impact of participating securities, all net of any associated tax impact. We also exclude tax benefits from the release of tax reserves, discrete tax adjustments including transfer pricing, tax deduction and tax credit adjustments, and the impact of tax law changes. We adjust these amounts from our non-GAAP and combined comparative measures primarily because management does not believe they are consistent with the development of our target operating model. Combined comparative results refer to the results for periods prior to the acquisition of Polycom, which were prepared by combining the non-GAAP results of as if they had been combined during that period. These prior period results are presented on a non-GAAP as-reported basis, with immaterial adjustments to align the treatment of non- GAAP adjustments for comparative purposes. We believe that the use of non-GAAP and combined comparative financial measures provides meaningful supplemental information regarding our performance and liquidity and helps investors compare actual results with our historical and long-term target operating model goals as well as our performance as a combined company. We believe presenting non-GAAP net revenue provides meaningful supplemental information regarding how management views the performance of the business and underlying performance of our individual product categories. We believe that both management and investors benefit from referring to these non-GAAP and combined comparative financial measures in assessing our performance and when planning, forecasting and analyzing future periods; however, non-GAAP and combined comparative financial measures are not meant to be considered in isolation of, or as a substitute for, or superior to, net revenues, gross margin, operating expenses, operating income, operating margin, net income or EPS prepared in accordance with GAAP. A reconciliation between GAAP and Non-GAAP measures for all periods presented in this document is included as an appendix to this document and in our press release regarding our results for Q4 FY20 filed with the SEC on Form 8-K on May 27, 2020.

Q1 GUIDANCE (AS OF MAY 27, 2020) Q1 FY21 Guidance GAAP Net Revenue $330M - $365M Non-GAAP Net Revenue1 $335M - $370M Adjusted EBITDA2 $25M - $45M Non-GAAP Diluted EPS2,3 $(0.18) - $0.22 1 The non-GAAP revenue guidance range shown here excludes the $5.1 million impact of purchase accounting related to recording deferred revenue at fair value at the time of the acquisition. 2 Q1 Adjusted EBITDA and non-GAAP diluted EPS excludes estimated intangibles amortization expense of $32.4 million. 3 EPS Guidance assumes approximately 41 million diluted average weighted shares and a non-GAAP effective tax rate of 18% to 20%. Poly does not intend to update these targets during the quarter or to report on its progress toward these targets. Poly will not comment on these targets to analysts or investors except by its press release announcing its first quarter fiscal year 2021 results or by other public disclosure. Any statements by persons outside Poly speculating on the progress of the first quarter or full fiscal year 2021 will not be based on internal company information and should be assessed accordingly by investors. Please refer to the appendix in this presentation and to our press release regarding our Q4 FY20 filed with the SEC on Form 8-K on May 27, 2020 for a reconciliation between GAAP and Non-GAAP measures. With respect to adjusted EBITDA and diluted EPS guidance, the Company has determined that it is unable to provide quantitative reconciliations of these forward-looking non-GAAP measures to the most directly comparable forward-looking GAAP measures with a reasonable degree of confidence in their accuracy without unreasonable effort, as items including stock based compensation, acquisition and integration costs, litigation gains and losses, and impacts from discrete tax adjustments and tax laws are inherently uncertain and depend on various factors, many of which are beyond the Company's control. Our business is inherently difficult to forecast, particularly with continuing uncertainty in regional economic conditions, currency fluctuations, customer cancellations and rescheduling, and there can be no assurance that expectations of incoming orders over the balance of the current quarter will materialize. © 2020 Plantronics Inc.
