NeoPhotonics Reports Second Quarter 2022 Financial Results

•Revenue of $95.0 million represents 46% year-over-year growth over same quarter last year

•Second sequential quarter with 45+% year-over-year growth; first half revenue of $184 million up 46% from same period last year

•$61 million of revenue from products for 400G and above applications, contributing 64% of revenue and representing approximately 105% year-over-year growth.

•GAAP Operating Profit of $6.4 million, up from a loss of $16.3 million in the same period last year on the strength of the 400G product ramp

SAN JOSE, Calif. — July 25, 2022 - NeoPhotonics Corporation (NYSE: NPTN), a leading developer of silicon photonics and advanced hybrid photonic integrated circuit-based lasers, modules and subsystems for bandwidth-intensive, high-speed communications networks, today announced financial results for its second quarter of 2022.

“Our business remains on a strong growth path with revenue of $95 million, 46% above the same quarter last year and also up 46% year-to-date. This was despite ongoing supply chain limitations which had an adverse impact on revenue of approximately $10 million. Our 400G and above products grew approximately 105% year-over-year, and now comprise 64% of total revenue. Our revenue from 400ZR coherent DCO module products to datacenter customers is now in low millions per quarter,” said Tim Jenks, Chairman and CEO of NeoPhotonics. “In addition to 400ZR, we are ramping our 96 Gbaud components and sampling 130 Gbaud for even higher data rate applications. These new component products, together with our ramping 400ZR and CFP2 400G module products, give us confidence in continued growth for the quarters ahead, despite the expected challenges with IC chip supply shortages.”

Mr. Jenks continued, “I would like to thank NeoPhotonics employees for their continued commitment, which has built the Company’s strong technology leadership for high speed over distance applications and has resulted in the Company’s strong performance in the second quarter of 2022.”

Mr. Jenks concluded, “The Lumentum transaction, announced last November, remains on track having been approved by our shareholders and received antitrust clearance from US regulators. We look forward to securing regulatory approval in China and closing the transaction. Our strong quarter with more than 46% year over year revenue growth, GAAP operating profit and significant growth from western customers, reflects our success in pivoting our business following the loss of revenue in 2020 due to Department of Commerce restrictions on certain Chinese customers.”

Second Quarter 2022 Summary

•Revenue of $95.0 million was up 46% year-over-year on growth in 400G and above capable products and up 6% quarter-over-quarter. Supply chain shortages negatively impacted revenue by approximately $10 million in the second quarter. Demand remains strong and chip supply continues to constrain revenue.

•Three customers were greater than 10% of our revenue for the three months ended June 30, 2022 and our top five customers accounted for 83% of our revenue in the quarter versus 77% in the same quarter last year.

Exhibit 99.1

•Gross margin was 34.8%, up nearly 20 percentage points year-over-year on improved factory utilization and up 4.2 percentage points from the prior quarter on meaningful yield improvements.

•Non-GAAP gross margin was 35.2% up from 21.7% in the same quarter last year and 31.2% in the prior quarter.

•Operating expense was $26.7 million, down $3.4 million from Q1’22 on a gain on the sale of our Fremont wafer fab and lower costs related to the sale.

•Non-GAAP operating expense of $24.1 million, down $0.9 million from Q1’22 on lower R&D materials & operating costs of the Fremont site.

•Operating income was $6.4 million, compared to a loss of $2.8 million in Q1’22 and a loss of $16.3 million in Q2’21, driven by the significant improvement in revenue and gross margin.

•Non-GAAP operating income was $9.4 million, compared to a loss of $10.3 million in Q2’21 and a profit of $2.8 million in the prior quarter, a notable turnaround in results.

•Foreign Exchange was a gain of $6.0 million on the appreciation of the U.S. dollar. As a reminder, the foreign exchange impact is largely related to the revaluation of U.S. dollar assets on our overseas books which are stated in their local currency. Beginning this quarter, we will exclude unrealized foreign exchange from our Non-GAAP results, to better focus on our operational results.

•Net earnings per share was $0.17, compared to net loss of $0.34 a year ago and a loss of $0.06 per share in the prior quarter.

•Non-GAAP net income per share was $0.15, compared to a Non-GAAP loss per share of $0.22 a year ago and a Non-GAAP earnings per share of $0.04 in the prior quarter. Excluding the impact of unrealized foreign exchange in the prior quarters, earnings per share was a loss of $0.22 in Q2’21 and an income of $0.05 in Q1’22.

•Adjusted EBITDA was $13.2 million, up from $7.8 million in the prior quarter excluding the impact of unrealized foreign exchange.

•Net Inventory grew $5.8 million from Q1’22, to $66 million, as we increased 400ZR inventories to a total of $20 million to ensure ongoing module supply.

•As of June 30, 2022, cash and cash equivalents, short-term investments and restricted cash totaled $105 million, down approximately $2.0 million from Q1’22. Capital Expenditure was $3 million.

Non-GAAP results in the second quarter of 2022 exclude gains of $5.4 million for unrealized foreign exchange, $1.9 million on the sale of assets, expenses of $2.6 million for stock-based compensation, $2.0 million of merger retention and other acquisition related charges, income tax effect of $1.4 million for Non-GAAP items and $0.2 million of other charges. A reconciliation of the non-GAAP and Adjusted EBITDA financial measures to the most directly comparable GAAP financial measures is provided in the financial schedules portion at the end of this press release.

NeoPhotonics Product Milestone Achievements

•Products capable of use for 400G and above applications were 64% of revenue in Q2 2022.

•Continued to ramp production of our 400ZR small form factor coherent transceiver modules, reaching low single digit millions in revenue.

•Shipped first samples of 130 Gbaud Coherent Receivers and Modulators for next generation 800G and 1.6T links.

•Conducted webinar outlining the application of NeoPhotonics coherent products and technology to Lidar for Autonomous Vehicles and other remote sensing applications.

Supply Chain Impacts

2

Exhibit 99.1

Second quarter revenue was approximately $10 million lower than we project it would have been without supply chain constraints. Supply chain impacts in the quarter were primarily shortages of analog and power semiconductors. The Company expects such impacts to continue through 2022.

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 directly comparable GAAP financial measures is provided in the financial schedules portion at the end of this press release. These 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 other companies. 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-period comparisons. 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 more complete understanding of factors and trends affecting its business.

Conference Call

The Company will not host a conference call regarding the Q2 2022 results.
