These forward-looking statements reflect MACOM's current views about future events and are subject to risks, uncertainties, assumptions and changes in circumstances that may cause those events or our actual activities or results to differ materially from those expressed in any forward-looking statement. Although MACOM believes that the expectations reflected in the forward-looking statements are reasonable, it cannot and does not guarantee future events, results, actions, levels of activity, performance or achievements. Readers are cautioned not to place undue reliance on these forward-looking statements. A number of important factors could cause actual results to differ materially from those indicated by the forward-looking statements, including the potential that we are unable to identify and timely enter into new markets for our products, such as our publicly-announced market opportunities in Cloud Data Centers, 100G optical networks, 10G PON, 25G lasers, L-PICs, GaN technology and Active Antennas, the potential that we are unable to timely deliver the quantities of our products targeting these or other applications at the right price point due to design challenges, manufacturing bottlenecks, supply shortages, yield issues or otherwise, the potential that the expected rollout of Cloud Data Center build-outs, 5G network upgrades, fiber-to-the-home network technology or other new optical or other network technology deployments in the U.S., China, Japan and other geographies fails to occur, occurs more slowly than we expect or does not result in the amount or type of new business we anticipate, lower than expected demand in the Cloud Data Center market, the optical network infrastructure market or any or all of our primary end markets or from any or all of our large OEM customers based on seasonal effects, regulatory action (such as the recently announced ZTE export ban or Huawei investigation) or inaction, technology shifts, standards changes, macro-economic weakness or otherwise, the potential for greater than expected pricing pressure and average selling price erosion based on attempts to win or maintain market share, competitive factors, technology shifts or otherwise, our potential inability to ramp key new products into volume production with acceptable manufacturing yields to satisfy key customer demand in a timely fashion, the potential for inventory obsolescence and related write-offs, a delay in consummating or failure to consummate the LR4 subassembly divestment based on required regulatory approvals or otherwise, the expense, business disruption or other impact of any current or future investigations, administrative actions, litigation or enforcement proceedings we may be involved in, the potential loss of access to any in-licensed intellectual property or inability to license technology we may require on reasonable terms, the impact of any claims of intellectual property infringement or misappropriation, which could require us to pay substantial damages for infringement, expend significant resources in prosecuting or defending such matters or developing non-infringing technology, incur material liability for royalty or license payments, or prevent us from selling certain of our products, greater than expected dilutive effect on earnings of our equity issuances, outstanding indebtedness and related interest expense and other costs, our failure to realize the expected economies of scale, lowered production cost, increased customer penetration and other anticipated benefits of our previously announced GaN intellectual property licensing program or supply chain build-out initiatives, the potential for defense spending cuts, program delays, cancellations or sequestration, failures or delays by any customer in winning business or to make purchases from us in support of such business, lack of adoption or delayed adoption by customers and industries we serve of Cloud Data Centers, MACsec, single-Lambda PAM4, MMICs, L-PICs, Active Antennas, SPAR tiles, GaN, InP lasers or other solutions offered by us, failures or delays in porting and qualifying GaN or InP process technology to our fabrication facilities or third party facilities and achieving anticipated manufacturing economies of scale, lower than expected utilization and absorption in our manufacturing facilities, lack of success or slower than expected success in our new product development or new product introduction efforts, loss of key personnel to competitors or otherwise, failure of any announced transaction to close in accordance with its terms, failure to successfully integrate acquired companies, technologies or products or realize synergies associated with acquisitions, the potential that we will experience difficulties in managing the personnel and operations associated with our acquisitions, loss of business due to competitive factors, product or technology obsolescence, customer program shifts or otherwise, the potential for a shift in the mix of products sold in any period toward lower-margin products or a shift in the geographical mix of our revenues, the impact of any executed or abandoned acquisition, divestiture, joint venture, financing or restructuring activity, the impact of supply shortages or other disruptions in our internal or outsourced supply chain, the impact of changes in export, environmental or other laws applicable to us, the relative success of our cost-savings initiatives, as well as those factors described in "Risk Factors" in MACOM's filings with the Securities and Exchange Commission ("SEC"), including its Annual Report on Form 10-K for the fiscal year ended September 29, 2017, as filed on November 15, 2017, and its Quarterly Report on Form 10-Q for the fiscal quarter ended December 29, 2017, as filed on February 7, 2018. MACOM undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

Discussion Regarding the Use of Historical and Forward-Looking Non-GAAP Financial Measures
In addition to GAAP reporting, MACOM provides investors with financial measures that have not been calculated in accordance with United States Generally Accepted Accounting Principles ("GAAP"), such as: non-GAAP gross profit and gross margin, non-GAAP income from operations and operating margin, non-GAAP operating expenses, non-GAAP net income, non-GAAP diluted earnings per share, adjusted EBITDA, and Free Cash Flow. From time to time in this release or elsewhere, we may alternatively refer to such non-GAAP measures as “adjusted” measures. This non-GAAP information excludes the effect, where applicable, of discontinued operations, intangible amortization expense, share-based compensation costs, impairment and restructuring charges, changes in common stock warrant liability, financing and litigation costs, acquisition and integration related costs, other costs and the tax effect of each adjustment. The non-GAAP information includes consulting agreement related income associated with the Automotive divestiture.
