FORWARD LOOKING STATEMENTS This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including statements relating to our intentions, beliefs, projections, outlook, analyses or current expectations that are subject to many risks and uncertainties. Such forward-looking statements and the associated risks and uncertainties include, but are not limited to: (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) our expectations the virus has caused and will continue to cause an increase in customer and partner demand for our product lines, including increased demand in collaboration endpoints, and our ability to design new product offerings to meet the change in demand due to a global hybrid work environment; (b) our inability to source component parts from key suppliers in sufficient quantities necessary to meet the high demand for certain product lines, including our Enterprise Headsets; and continued uncertainty and potential impact on future quarters if these sourcing constraints continue and/or price volatility occurs, which could continue to negatively affect our profitability and/or market share; (c) expectations related to our voice product lines, as well as our services attachment rate for such products, which have been, and may continue to be, negatively impacted as companies have delayed returning their workforces to offices in many countries due to the continued impact of COVID-19; (d) expectations related to our ability to fulfill the backlog generated by supply constraints, to timely supply the number of products to fulfill current and future customer demand, including expectations that our manufacturing facility in Tijuana, Mexico will continue production at the capacity necessary to meet such demand; (e) 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; (f) 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; (g) risks related to restrictions or delays in global return to worksites as a result of COVID-19, which continues to impact our employees worldwide and our customers, which has negatively impacted our voice product lines for the quarter, and restricted customer engagement; and (h) the complexity of the forecast analysis 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 perishable demand; (iii) expectations related to our customers’ purchasing decisions and our ability to pivot quickly enough and/or 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, which has negatively impacted in the quarter and may continue to impact our ability to timely supply product to meet our customer demand; (vii) expectations related to our services segment revenues, particularly as we introduce new generation, less complex, product solutions, or as companies shift from on premises to work from home options for their workforce, which may result in decreased demand for our professional, installation and/or managed service offerings; (viii) 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 suspend our dividend payments, will meet our liquidity needs during and following the unknown duration and impact of the COVID-19 pandemic; (ix) 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; (x) 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; (xi) our efforts to execute to drive sales and sustainable profitable revenue growth, to improve our profitability and cash flow, and accelerate debt reduction and de-levering; (xii) our expectations for new products launches, the timing of their releases and their expected impact on future growth and on our existing products; (xiii) our belief that our Partner Program will drive growth and profitability for both us and our partners through the sale of our product, services and solutions; (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, including, without limitation, uncertainty related to the continued impact of COVID-19, the macro-economic and political climate and other external factors, puts further pressure on management judgments used to develop forward looking financial guidance and other prospective financial information; (xviii) expectations related to GAAP and non-GAAP financial results for the second quarter and full Fiscal Year 2021, including net revenues, adjusted EBITDA, tax rates, intangibles amortization, 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; (xxi) our belief that the increased adoption of certain technologies and our open architecture approach has and will continue to increase demand for our solutions; (xxii) expectations related to the micro and macro-economic conditions in our domestic and international markets and their impact on our future business; (xxiii) our forecast and estimates with respect to tax matters, including expectations with respect to utilizing our deferred tax assets; (xxiv) our expectations related to building strategic alliances and key partnerships with providers of collaboration tools and platforms to drive revenue growth and market share; and (xxv) our expectations regarding pending and potential future litigation, in addition to other matters discussed in this press release that are not purely historical data. Such forward-looking statements are based on current expectations and assumptions and are subject to risks and uncertainties that may cause actual results to differ materially from the forward-looking statements. 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 June 8, 2020 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-GAAP measures of operating results, including non-GAAP net revenues, non-GAAP gross profit, non-GAAP operating expenses, non-GAAP operating income, non-GAAP net 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, 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 measures primarily because management does not believe they are consistent with the development of our target operating model. We believe that the use of non-GAAP 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 financial measures in assessing our performance and when planning, forecasting and analyzing future periods; however, non-GAAP 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 Q2 FY21 filed with the SEC on Form 8-K on October 29, 2020.

Q3 GUIDANCE (AS OF OCTOBER 29, 2020) Q3 FY21 Guidance GAAP Net Revenue $417M - $447M Non-GAAP Net Revenue1 $420M - $450M Adjusted EBITDA2 $70M - $80M Non-GAAP Diluted EPS2,3 $0.85 – $1.05 1 The non-GAAP revenue guidance range shown here excludes the $3.3 million impact of purchase accounting related to recording deferred revenue at fair value at the time of the acquisition. 2 Q3 Adjusted EBITDA and non-GAAP diluted EPS excludes estimated intangibles amortization expense of $30.7 million. 3 EPS Guidance assumes approximately 42 million diluted average weighted shares and a non-GAAP effective tax rate of 11% to 13%. 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 third quarter fiscal year 2021 results or by other public disclosure. Any statements by persons outside Poly speculating on the progress of the third 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 Q2 FY21 filed with the SEC on Form 8-K on October 29, 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.
