Non-GAAP and Adjusted EBITDA Measures vs. GAAP Financial Measures

The Company’s non-GAAP and adjusted EBITDA measures exclude certain GAAP financial measures. A reconciliation of the Non-GAAP and Adjusted EBITDA financial measures to the most directlycomparable GAAP financial measures is provided in the financial schedules portion of its press release issued on August 4, 2020 and available in the Investor Relations section of the NeoPhotonicswebsite. Non-GAAP financial measures differ from GAAP measures with the same captions and may differ from non-GAAP financial measures with the same or similar captions that are used by othercompanies. As such, these non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP.

The Company uses these non-GAAP financial measures to analyze its operating performance and future prospects, develop internal budgets and financial goals, and to facilitate period-to-periodcomparisons. NeoPhotonics believes that these non-GAAP financial measures reflect an additional way of viewing aspects of its operations that, when viewed with its GAAP results, provide a morecomplete understanding of factors and trends affecting its business.

Heightened Importance In New 600~800G Links:NPTN Lasers are Ultra Accurate and Stable To Enable Highest Fiber Capacity

• NPTN Ultra Narrow Linewidth Tunable Lasers have frequency stability and accuracy that is 2X as good as the main competition, DBR lasers.

• 600G (≤ 70Gbaud) often uses 75GHz-spaced athermal DWDM array-waveguide multiplexer/de-multiplexer or ROADM to avoid a reduction of total fiber capacity.

• 800G (≤ 96Gbaud) uses 100GHz to 125GHz-spaced DWDM multiplexer/de-multiplexer or ROADM for similar reasons.

• These tight channel spacings leave little margin for laser or optics drift. In these areas, NeoPhotonics high performance components enable the highest capacity.

Summary

• 400G+ is the fastest growing segment for Cloud and telecom networks.

• In 2021~2023, cloud and telecom networks both need 400ZR and 400ZR+ pluggable modules and 600~800G chassis-based transport systems.

– NeoPhotonics’ DD-QSFP, OSFP, and CFP2-DCO modules cover 400ZR and 400ZR+– NeoPhotonics’ tunable lasers, HB-CDM, and HB-ICR components cover 600~800G

• NPTN is well positioned for this growth.

Our new era of growth is driven by the highest speed chassis-based systems in addition to the sea change from advent of 400ZR and 400ZR+ modules in 2021.• NPTN also enables critical Open Line Systems for 400G and above with our Networks Products

and Solutions.

• 400G+ solutions are deploying now and will serve the longest reach and “biggest” data pipes.

Key trends and technology paths are clear in delivering highest speed over distance

NPTN reaffirms Q3 outlook of $97-105 milA New Era of Growth, Driven by 400G~800G

A New Era of Growth for NeoPhotonics

• Demand for NPTN high speed products is strong.• Hyper-scale data center interconnects, expanding

high speed capacities and network edge provisioning for cloud services all drive demand for speed over distance.

• Our highest speed products for 400G, 600G and 800G are gaining traction with leading NEMs. These are expected to be 20-25% of 2020 revenue and exit the year at >40%.

• We expect 40-50% revenue growth from customers beyond Huawei over the next year.

• 400ZR and 400ZR+ high speed modules are expected to ramp in 2021. Port growth is forecasted at an 80% CAGR 2019-2024.

• Recent BIS / Department of Commerce increased restrictions on Huawei for U.S. and foreign-produced items using U.S. technology

• We expect to meet our Q3 2020 outlook provided on August 4, 2020. Shipments to Huawei in Q3 are expected to contribute ~$40 mil of revenue in Q3.

• Beyond Q3, assuming BIS restrictions remain in place and provided we are unable to obtain licenses, NPTN will not rely on revenue contribution from Huawei.

34

Outlook for Q3’20: No Change from August 4th Outlook

• Q3’20 Non-GAAP Gross Margin reflects an increase in underutilization; customer projects delayed by Covid-19.

• Supply Chain risks continue, but we are expecting to continue to be able to mitigate the risks.

• Operating Expense reflects push out of H1’20 expenses to H2’20 to ensure continued success in customer qualification of 64 Gbaud and 400ZR products.

• Given current trends in FX, the EPS forecast includes $1M of unfavorable impact for FX.

Notes: Q3’20 non-GAAP outlook excludes $3.4M of anticipated stock-based compensation expense, $0.3M of amortization of acquisition related intangibles and other costs, and $0.4M of non-GAAP tax adjustments. Non-GAAP EPS outlook assumes approximately 54.7 million fully diluted shares outstanding.

GAAP Non-GAAP

Revenue $97M to $105M

Gross Margin 29% to 33% 30% to 34% Operating Expenses $28M to $29M $25M to $26M

EPS ($0.03) to $0.07 $0.03 to $0.13

Based on current information, profitability is expected to continue for the 5th consecutive quarter. Demand for network bandwidth capacity continues to be strong. Completion of strategic inventory build at Huawei is expected to be offset by growth from other Top 10 customers for our highest speed products.Outlook reflects company view of update Entities List rules.

35

The target for Gross Margin remains 35%

Drivers and Trends

Product margins have increased 10%+ since Q1’19and will increase slightly on improved product mix.

Eliminating 40% of revenue, excess capacity chargeswill increase significantly.

Insourcing of new products to leveraging capacity

Start up costs for modules to drive growth andcustomer diversification

Operating Profit

We will return to operating losses beginning Q4’20, without Huawei revenues We are forecasting a return to operating profits by the end of 2021

NPTN team has a proven track record of improving results for cash, cash flow and profitability

Gross Margin Operating ExpenseThe target for OpEx remains 25% of revenue

Drivers and Trends

Complete start up of modules at new customer group

Review products and programs for highest return

SG&A difficult to scale

Variable compensation reduced on reduced profitability

36
