Prime World is also the parent of Global Technology, Inc. (“Global”, incorporated in the People’s Republic of China). Through Global, the Company primarily manufactures certain of its data center transceiver products, including subassemblies, as well as CATV systems and equipment, and performs research and development activities for the CATV products.

Interim Financial Statements

The unaudited condensed consolidated financial statements of the Company as of June 30, 2021 and December 31, 2020 and for the three and six months ended June 30, 2021 and June 30, 2020 , have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim information and with the instructions on Form 10 -Q and Rule 10 - 01 of Regulation S- X pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In accordance with those rules and regulations, the Company has omitted certain information and notes required by GAAP for annual consolidated financial statements. In the opinion of management, the condensed consolidated financial statements contain all adjustments, except as otherwise noted, necessary for the fair presentation of the Company’s financial position and results of operations for the periods presented. The year-end condensed balance sheet data was derived from audited financial statements. These condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10 -K (“Annual Report”) for the fiscal year ended December 31, 2020 . The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results expected for the entire fiscal year. All significant inter-company accounts and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates in the consolidated financial statements and accompanying notes. Significant estimates and assumptions that impact these financial statements and the accompanying notes relate to, among other things, allowance for credit losses, inventory reserve, product warranty costs, share-based compensation expense, estimated useful lives of property and equipment, and taxes.

Note 2. Significant Accounting Policies

There have been no changes in the Company’s significant accounting policies for the three and six months ended June 30, 2021 , as compared to the significant accounting policies described in its 2020 Annual Report, except as described below.

Recent Accounting Pronouncements

Recent Accounting Pronouncements Yet to be Adopted

In March 2020, the FASB issued ASU 2020 - 04, “Reference Rate Reform (Topic 848 ): Facilitation of the Effects of Reference Rate Reform on Financial Reporting”, which provides temporary optional expedients and exceptions to the GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered r ates to alternative reference rates. ASU 2020 - 04 was further amended in January 2021 by ASU 2021 - 01, which clarified the applicability of certain provisions. Both ASU 2020 - 04 and AUC 2021 - 01 are currently effective prospectively for all entities through December 31, 2022 when the reference rate replacement activity is expected to have completed. The guidance in ASU 2020 - 04 and AUC 2021 - 01 is optional and may be elected over time as reference rate reform activities occur. As of June 30, 2021, the Company is evaluating the impact this standard may have on its consolidated financial statements.

In August 2020, the FASB issued ASU 2020 - 06, “Debt - Debt with Conversion and Other Options (Subtopic 470 - 20 )” and “Derivatives and Hedging - Contracts in Entities Own Equity” (Subtopic 815 - 40 ). This ASU simplifies accounting for convertible instruments by eliminating two of the three models in ASC 470 - 20 that requires separating embedded conversion features from convertible instruments. The guidance is effective for fiscal years beginning after December 15, 2021. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements.

In November 2020, the SEC issued a new rule that modernizes and simplifies various aspects and financial disclosure requirements in Regulation S-K, specifically related to Item 301 “Selected Financial Data”, Item 302 “Supplementary Financial Information” and Item 303 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (“MD&A”). The intent of this new rule is to (i) eliminate duplicative disclosures, (ii) enhance and promote more principles-based MD&A disclosures with the objective of making them more meaningful for investors, all while (iii) simplifying the compliance requirements and efforts for registrants, by providing them with the flexibility to present management’s perspective on the registrant’s financial condition and results of operations. While most of the changes involve reducing or eliminating previously required information and disclosures, the rule does expand the disclosure requirements surrounding certain aspects of the various items in Regulation S-K discussed above. The final rule was published in the Federal Register on January 11, 2021, is effective thirty days after its publication date, or February 10, 2021, and registrants are required to comply with this final rule in the registrant’s first fiscal year ending on or after the date that is 210 days after the publication date. The Company plans to comply with the new disclosure requirements on schedule and currently does not anticipate any material financial impact in complying with these new requirements.

Note 4. Leases

The Company leases space under non-cancellable operating leases for manufacturing facilities, research and development offices and certain storage facilities and apartments. These leases do not contain contingent rent provisions. The Company also leases certain machinery, office equipment and a vehicle. Many of its leases include both lease (e.g. fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g. common-area or other maintenance costs) which are accounted for as a single lease component as the Company has elected the practical expedient to group lease and non-lease components for all leases. Several of the leases include one or more options to renew which have been assessed and either included or excluded from the calculation of the lease liability of the right of use ("ROU") asset based on management’s intentions and individual fact patterns. Several warehouses and apartments have non-cancellable lease terms of less than one -year and therefore, the Company has elected the practical expedient to exclude these short-term leases from its ROU asset and lease liabilities.

As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Based on the applicable lease terms and current economic environment, the Company applies a location approach for determining the incremental borrowing rate.

Note 6. Earnings (Loss) Per Share

Basic net loss per share has been computed using the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share has been computed using the weighted-average number of shares of common stock and dilutive potential common shares from stock options, restricted stock units and senior convertible notes outstanding during the period. In periods with net losses, normally dilutive shares become anti-dilutive. Therefore, basic and diluted loss per share are the same.

The following table sets forth the computation of the basic and diluted net loss per share for the periods indicated (in thousands):

The carrying value amounts of accounts receivable, note receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other current liabilities approximate fair value because of the short-term maturity of these instruments. The carrying value amounts of bank acceptances approximate fair value due to the short-term nature of the debt since it renews frequently at current interest rates. The Company believes that the interest rates in effect at each period end represent the current market rates for similar borrowings.

The fair value of its convertible senior debt is measured for disclosure purpose. The fair value is based on observable market prices for this debt, which is traded in less active markets and are therefore classified as a Level 2 fair value measurement.

On September 28, 2017, the Company entered into a Loan Agreement (“Loan Agreement”), a Promissory Note, an Addendum to the Promissory Note, a Truist Bank Security Agreement, a Trademark Security Agreement, and a Patent Security Agreement (together the “Credit Facility”) with Truist Bank (which acquired Branch Banking and Trust Company or BB&T in connection with a merger in December 2019). The Company’s obligations under the Credit Facility are secured by the Company’s accounts receivable, inventory, intellectual property, and all business assets with the exception of real estate and equipment.

On September 30, 2019, the Company executed a Fourth Amendment to Loan Agreement (the “Fourth Amendment”) with Truist Bank. Under the terms of the Fourth Amendment (i) the maximum commitment under the line of credit was reduced from $ 25,000,000 to $20,000,000; (ii) the maturity date of the line of credit was extended from September 28, 2020 to April 2, 2021; ( iii) pricing of the unused line fee was adjusted to 0.30 % per annum; and (iv) created the requirement that if, at any time during any reporting period and pursuant to the most recent loan base report received by Truist Bank, the principal balance outstanding under the line of credit exceeds the lesser of the approved maximum amount of the line of credit commitment amount or the collateral loan value reduced by the reserves, the Company shall immediately prepay the line of credit to the extent necessary to eliminate such excess. Such reserves shall, at any time that the fixed charge coverage ratio for the loan is less than 1.5 to 1.0, tested for the period of twelve months ended on the applicable covenant measurement date, equal to an amount equal to seventy-five percent ( 75 %) of the lesser of the line of credit commitment amount or collateral loan value reduced by the sum of (i) the principal balance outstanding under the line of credit, (ii) the letter of credit exposure reserve, and (iii) the availability reserve as determined by Truist Bank from the most recent loan base report and otherwise in the sole discretion of Truist Bank after consideration of collections.

On April 5, 2021, the Company executed a Fifth Amendment to the Loan Agreement (the "Fifth Amendment") and a Fourth Amendment to a Security Agreement, a Note Modification Agreement, and an Addendum to a Promissory Note (together with the Fifth Amendment the “Amended Credit Facility”) with Truist Bank. The Amended Credit Facility renews the $ 20 million line of credit with Truist bank originally entered into on September 28, 2017. Under the terms of the Amended Credit Facility, the maturity date of the line of credit is extended from April 2, 2021 to October 15, 2022. Borrowings will bear interest at a rate equal to LIBOR plus 1.5 %, with a LIBOR floor of 0.75 %. As of June 30, 2021 , the Company had $ 19.4 million outstanding and was in compliance with all covenants under the Amended Credit Facility.

On April 17, 2020, the Company entered into a term note ("PPP Term Note") with Truist Bank, with a principal amount of $ 6.23 million pursuant to the Paycheck Protection Program (“PPP”) under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The PPP loan is evidenced by a promissory note. The PPP Term Note bears interest at a fixed annual rate of 1.00%, with the first six months of interest deferred. Beginning in November 2020, the Company is required to make 18 equal monthly payments of principal and interest with the final payment due in April 2022. The PPP Term Note may be accelerated upon the occurrence of an event of default. The PPP Term Note is unsecured and guaranteed by the United States Small Business Administration ("SBA"). On June 14, 2021, the Company received notification from Truist Bank that the SBA approved the Company's application for forgiveness of the entire principle amount of the PPP Term Note, plus all accrued interest. The forgiveness of the PPP Term Note has been recognized as other income during the second quarter ended June 30, 2021.

On September 15, 2020, Prime World entered into an Amendment to the Finance Lease Agreements dated November 29, 2018 and January 21, 2019 ( the “Amendment”) with Chailease Finance Co., Ltd.

Global’s obligations under the China Merchants Credit Line are unsecured. The China Merchants Credit Line has been replaced by the Replacement China Merchants Credit Line on October 19, 2020 .

On May 24, 2019, the Company’s China subsidiary, Global, entered into a five -year revolving credit line agreement, totaling 180,000,000 RMB (the “SPD Credit Line”), or approximately $ 25.4 million, and a mortgage security agreement (the “Security Agreement”), with SPD.

Each draw will bear interest equal to CZB’s commercial banking interest rate effective on the day of the applicable draw. Global’s obligations under the ¥100M Credit Facility will be secured by real property owned by Global and mortgaged to CZB under the terms of the Real Estate Security Agreement. The agreements for the ¥100M Credit Facility and the Real Estate Security Agreement also contain rights and obligations, representations and warranties, and events of default applicable to the Company that are customary for agreements of this type.

Note 12. Convertible Senior Notes

On March 5, 2019, the Company issued $ 80.5 million of 5 % convertible senior notes due 2024 (the “Notes”). The Notes were issued pursuant to an indenture, dated as of March 5, 2019 (the “Indenture”), between the Company and Wells Fargo Bank, National Association, as trustee, paying agent, and conversion agent (the “Trustee”). The Notes bear interest at a rate of 5.00% per year, payable in cash semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2019. The Notes will mature on March 15, 2024, unless earlier repurchased, redeemed or converted in accordance with their terms.

The sale of the Notes generated net proceeds of $ 76.4 million, after deducting the Initial Purchasers’ discounts and offering expenses payable by the Company. The Company used approximately $ 37.8 million of the net proceeds from the offering to fully repay the CapEx Loan and Term Loan with Truist Bank and the remainder will be used for general corporate purposes.

The following table presents the carrying value of the Notes for the periods indicated (in thousands):

Net carrying amount

$ 78,264 $ 77,854

The Notes are convertible at the option of holders of the Notes at any time until the close of business on the scheduled trading day immediately preceding the maturity date. Upon conversion, holders of the Notes will receive shares of the Company’s common stock, together, if applicable, with cash in lieu of any fractional share, at the then-applicable conversion rate. The initial conversion rate is 56.9801 shares of the Company’s common stock per $ 1,000 principal amount of Notes (representing an initial conversion price of approximately $ 17.55 per share of common stock, which represents an initial conversion premium of approximately 30 % above the closing price of $ 13.50 per share of the Company’s common stock on February 28, 2019 ), subject to customary adjustments. If a make-whole fundamental change (as defined in the Indenture) occurs, and in connection with certain other conversions before March 15, 2022, the Company will in certain circumstances increase the conversion rate for a specified period of time.

Initially there are no guarantors of the Notes, but the Notes will be fully and unconditionally guaranteed, on a senior, unsecured basis by certain of the Company’s future domestic subsidiaries.  The Notes are the Company’s senior, unsecured obligations and are equal in right of payment with existing and future senior, unsecured indebtedness, senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated to the Notes and effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness.  The Note Guarantee (as defined in the Indenture) of each future guarantor, if any, will be such guarantor’s senior, unsecured obligations and are equal in right of payment with existing and future senior, unsecured indebtedness, senior in right of payment to such future guarantor’s existing and future indebtedness that is expressly subordinated to the Notes and effectively subordinated to such future guarantor’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness.

Holders may require the Company to repurchase their Notes upon the occurrence of a fundamental change (as defined in the Indenture) at a cash purchase price equal to the principal amount thereof plus accrued and unpaid interest, if any.

The Company may not redeem the Notes prior to March 15, 2022. On or after March 15, 2022, the Company may redeem for cash all or part of the Notes if the last reported sale price per share of the Company’s common stock exceeds 130 % of the conversion price on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (ii) the trading day immediately before the date the Company sends such redemption notice.  The redemption price is equal to 100 % of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.  In addition, calling any Note for redemption will constitute a “make-whole fundamental change” with respect to that Note, in which case the conversion rate applicable to the conversion of that Note will be increased in certain circumstances if it is converted after it is called for redemption.

19

The Indenture contains covenants that limit the Company’s ability and the ability of our subsidiaries to, among other things: (i) incur or guarantee additional indebtedness or issue disqualified stock; and (ii) create or incur liens.

Pursuant to the guidance in ASC 815 - 40, Contracts in Entity’s Own Equity , the Company evaluated whether the conversion feature of the note needed to be bifurcated from the host instrument as a freestanding financial instrument. Under ASC 815 - 40, to qualify for equity classification (or non-bifurcation, if embedded) the instrument (or embedded feature) must be both ( 1 ) indexed to the issuer’s own stock and ( 2 ) meet the requirements of the equity classification guidance. Based upon the Company’s analysis, it was determined the conversion option is indexed to its own stock and also met all the criteria for equity classification contained in ASC 815 - 40 - 25 - 7 and 815 - 40 - 25 - 10. Accordingly, the conversion option is not required to be bifurcated from the host instrument as a freestanding financial instrument. Since the conversion feature meets the equity scope exception from derivative accounting, the Company then evaluated whether the conversion feature needed to be separately accounted for as an equity component under ASC 470 - 20, Debt with Conversion and Other Options .  The Company determined that notes should be accounted for in their entirety as a liability.

The Company incurred approximately $ 4.1 million in transaction costs in connection with the issuance of the Notes. These costs were recognized as a reduction of the carrying amount of the Notes utilizing the effective interest method and are being amortized over the term of the notes.

Note 16. Income Taxes

The Company’s effective tax rate for the three months ended June 30, 2021 and 2020 was 0 % and 258.2 %, respectively. For the three months ended June 30, 2021, the effective tax rate varied from the federal statutory rate of 21 % primarily due to the benefit of the nontaxable PPP loan forgiveness, offset by the change of the valuation allowance on federal, state, Taiwan, and China deferred tax assets ("DTA"). For the three months ended June 30, 2020, the effective tax rate varied from the federal statutory rate of 21 % primarily due to the level and mix of earnings among tax jurisdictions, and the change of valuation allowance on the US and state deferred tax assets, and the recording of a valuation allowance on Taiwan deferred tax assets.

The Company's effective tax rate for the six months ended June 30, 2021 and 2020 was 0 % and ( 16.25 %), respectively. For the six months ended June 30, 2021, the effective tax rate varied from the federal statutory rate of 21 % primarily due to the change of the valuation allowance on federal, state, Taiwan and China DTA. For the six months ended June 30, 2020, the effective tax rate varied from the federal statutory rate of 21 % primarily due to the level and mix of earnings among tax jurisdictions, the change of the valuation allowance on the US and state deferred tax assets, and the recording of a valuation on Taiwan deferred tax assets.

The Company continually monitors and performs an assessment of the realizability of its DTAs, including an analysis of factors such as future taxable income, reversal of existing taxable temporary differences, and tax planning strategies. In assessing the need for a valuation allowance, the Company considered both positive and negative evidence related to the likelihood of realization of deferred tax assets using a “more likely than not” standard. In making such assessment, more weight was given to evidence that could be objectively verified, including recent cumulative losses. Based on the Company’s review of this evidence, management determined that a full valuation allowance against all of the Company’s net deferred tax assets at June 30, 2021 was appropriate.

In response to the COVID- 19 pandemic, the Coronavirus Aid, Relief, and Economic Stability Act (the "CARES Act") was signed into law on March 27, 2020. The CARES Act, among other things, includes tax provisions relating to refundable payroll tax credits, deferment of employer social security payments, net operating loss utilization and carryback periods, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property (“QIP”). On December 27, 2020, the Taxpayer Certainty and Disaster Tax Relief Act of 2020 was enacted as part of the Consolidated Appropriations Act, 2021, followed by the American Rescue Plan Act on March 1, 2021. These recent laws, among many other provisions, expand and extend the Paycheck Protection Program  (“PPP”), refundable employee retention tax credits previously made available under the CARES Act and allow a full deduction for business meals for the 2021 and 2022 tax years. At this point we do not believe that these changes will have a material impact on our income tax provision for 2021. We will continue to evaluate the impact of new legislation on our financial position, results of operations, and cash flows.

From time to time, the Company may be subject to legal proceedings and litigation arising in the ordinary course of business, including, but not limited to, inquiries, investigations, audits and other regulatory proceedings, such as described below. The Company records a loss provision when it believes it is both probable that a liability has been incurred and the amount can be reasonably estimated. Unless otherwise disclosed, the Company is unable to estimate the possible loss or range of loss for the legal proceeding described below.

Except for the lawsuits described below, the Company believes that there are no claims or actions pending or threatened against it, the ultimate disposition of which would have a material adverse effect on it.

Class Action and Shareholder Derivative Litigation

On August 7, 2018, a derivative lawsuit was filed in the United States District Court for the Southern District of Texas styled Lei Jin, derivatively on behalf of Applied Optoelectronics, Inc. v. Chih-Hsiang ( Thompson ) Lin, Stefan J. Murry, William H. Yeh, Alex Ignatiev, Richard B. Black, Min-Chu Chen, Alan Moore, and Che-Wei Lin and Applied Optoelectronics, Inc. , No. 4:18 -cv- 02713 alleging breaches of fiduciary duties, unjust enrichment, and violations of Section 14 (a) of the Exchange Act based on similar factual allegations as in the securities class action captioned Mona Abouzied v. Applied Optoelectronics, Inc., Chih-Hsiang (Thompson) Lin, and Stefan J. Murry, et al. , Case No. 4:17 -cv- 02399, which had been previously filed against the Company and was dismissed following a settlement in 2020. On December 18, 2018, a second derivative complaint was filed styled Yiu Kwong Ng v. Chih-Hsiang ( Thompson ) Lin, Stefan J. Murry, William H. Yeh, Alex Ignatiev, Richard B. Black, Min-Chu Chen, Alan Moore, and Che-Wei Lin and Applied Optoelectronics, Inc. , No. 4:18 -cv- 4751 alleging the same causes of actions as the Jin complaint and additional factual allegations regarding our announcement on September 28, 2018 that we had “identified an issue with a small percentage of 25G lasers within a specific customer environment.”  On January 11, 2019, the court consolidated these two derivative actions, and on January 15, 2019, the court entered an order staying the actions pending the resolution of the securities class actions. On June 24, 2020, the plaintiffs filed a notice that the stay of proceedings had been terminated, and on July 2, 2020, the parties filed a Joint Stipulation and Proposed Scheduling Order. The court entered the stipulated scheduling order on the same date, under which Defendants were required to file and serve their response or responsive pleading to the complaint by August 3, 2020. By agreement of the parties, the Court subsequently extended the deadline for Defendants to file and serve their response or responsive pleading to December 2, 2020. On December 2, 2020, Defendants filed their motion to dismiss the consolidated derivative complaint. On December 7, 2020, Plaintiffs filed a notice alerting the Court that they were intending to file an amended complaint, which was subsequently filed by Plaintiffs on January 13, 2021. Defendants filed a motion to dismiss all claims on March 1, 2021. Plaintiffs’ response deadline is May 3, 2021. On June 25, 2021, the parties filed a stipulation indicating that they had reached a settlement-in-principle of the action. On June 28, 2021, the Court stayed all deadlines in the action for 30 days to allow the parties to finalize the settlement. The deadline was extended to August 13, 2021. At this stage, we are not yet able to determine the likelihood of loss, if any, arising from this matter.

Overview

We are a leading, vertically integrated provider of fiber-optic networking products. We target four networking end-markets: internet data centers, CATV, telecom and FTTH. We design and manufacture a range of optical communications products at varying levels of integration, from components, subassemblies and modules to complete turn-key equipment. In designing products for our customers, we typically begin with the fundamental building blocks of lasers and laser components. From these foundational products, we design and manufacture a wide range of products to meet our customers’ needs and specifications, and such products differ from each other by their end market, intended use and level of integration. We are primarily focused on the higher-performance segments within the internet data center, CATV, telecom and FTTH markets which increasingly demand faster connectivity and innovation. Our vertically integrated manufacturing model provides us several advantages, including rapid product development, fast response times to customer requests and control over product quality and manufacturing costs.

The four end markets we target are all driven by significant bandwidth demand fueled by the growth of network-connected devices, video traffic, cloud computing and online social networking. Within the internet data center market, we benefit from the increasing use of higher-capacity optical networking technology as a replacement for copper cables, particularly as speeds reach 100 Gbps and above, as well as the movement to open internet data center architectures and the increasing use of in-house equipment design among leading internet companies. Within the CATV market, we benefit from a number of ongoing trends including the build-out of CATV infrastructure in the US and other countries, the move to higher bandwidth networks among CATV service providers and the outsourcing of system design among CATV networking equipment companies. In the FTTH market, we benefit from continuing PON deployments and system upgrades among telecom service providers. In the telecom market, we benefit from deployment of new high-speed fiber-optic networks by telecom network operators, including 5G networks.

Our vertically integrated manufacturing model provides us several advantages, including rapid product development, fast response times to customer requests and greater control over product quality and manufacturing costs. We design, manufacture and integrate our own analog and digital lasers using a proprietary Molecular Beam Epitaxy, or MBE, and Metal Organic Chemical Vapor Deposition (MOCVD) fabrication process, which we believe is unique in our industry. We manufacture the majority of the laser chips and optical components that are used in our products. The lasers we manufacture are tested extensively to enable reliable operation over time and our devices are often highly tolerant of changes in temperature and humidity, making them well-suited to the CATV, FTTH and 5G telecom markets where networking equipment is often installed outdoors.

We have three manufacturing sites: Sugar Land, Texas, Ningbo, China and Taipei, Taiwan. Our research and development functions are generally partnered with our manufacturing locations, and we have an additional research and development facility in Duluth, Georgia. In our Sugar Land facility, we manufacture laser chips (utilizing our MBE and MOCVD processes), subassemblies and components. The subassemblies are used in the manufacture of components by our other manufacturing facilities or sold to third parties as modules. We manufacture our laser chips only within our Sugar Land facility, where our laser design team is located. In our Taiwan location, we manufacture optical components, such as our butterfly lasers, which incorporate laser chips, subassemblies and components manufactured within our Sugar Land facility. Additionally, in our Taiwan location, we manufacture transceivers for the internet data center, telecom, FTTH and other markets. In our China facility, we take advantage of lower labor costs and manufacture certain more labor intensive components and optical equipment systems, such as optical subassemblies and transceivers for the internet data center market, CATV transmitters (at the headend) and CATV outdoor equipment (at the node). Each manufacturing facility conducts testing on the components, modules or subsystems it manufactures and each facility is certified to ISO 9001:2015. Our facilities in Ningbo, China, Taipei, Taiwan, and Sugar Land, Texas are all certified to ISO 14001:2015.

Our business depends on winning competitive bid selection processes to develop components, systems and equipment for use in our customers’ products. These selection processes are typically lengthy, and as a result our sales cycles will vary based on the level of customization required, market served, whether the design win is with an existing or new customer and whether our solution being designed in our customers’ product is our first generation or subsequent generation product. We do not have any long-term purchase commitments (in excess of one year) with any of our customers, most of whom purchase our products on a purchase order basis. However, once one of our solutions is incorporated into a customer’s design, we believe that our solution is likely to continue to be purchased for that design throughout that product’s life cycle because of the time and expense associated with redesigning the product or substituting an alternative solution.

Our principal executive offices are located at 13139 Jess Pirtle Blvd., Sugar Land, TX 77478, and our telephone number is (281) 295-1800.

COVID-19 Pandemic

We are subject to risks and uncertainties as a result of the COVID-19 pandemic. The extent of the impact of the COVID-19 pandemic on our business is highly uncertain and difficult to predict as coronavirus continues to spread around the world. In March 2020, we instituted travel restrictions and implemented sanitation and disinfection procedures to safeguard the health and safety of our employees which continue today. Recently, we began allowing certain employee travel, but continue strict sanitation procedures in our facilities. With increased vaccinations and the potential significant reduction of infections, we have implemented procedures for a safe return to the office environment for all of our employees. How ever, the spread of COVID-19 may still impact our supply chain operations through restrictions, reduced capacity and shutdown of business activities by suppliers whom we rely on for sourcing components and materials and third-party partners whom we rely on for manufacturing, warehousing and logistics services. Although demand for many of our products has been strong in the short-term as subscribers seek more bandwidth, customers’ purchasing decisions over the long-term may be impacted by the pandemic and its impact on the economy, which could in turn impact our revenue and results of operations. The extent to which the COVID-19 pandemic may materially impact our financial condition, liquidity or results of operations is therefore uncertain.

Comparison of Financial Results

Revenue

We generate revenue through the sale of our products to equipment providers and network operators for the internet data center, CATV, telecom and FTTH markets. We derive a significant portion of our revenue from our top ten customers, and we anticipate that we will continue to do so for the foreseeable future. The following charts provide the revenue contribution from each of the markets we served for the three and six months ended June 30, 2021 and 2020 (in thousands, except percentages):

The decrease in revenue during the three and six months ended June 30, 2021 was driven primarily by decrease demand for datacenter segment; this slowdown was related to inventory normalization following the surge in demand that was driven by the shift to working from home early last year . We believe datacenter demand will improve in the second half and beyond. The decreased demand in the datacenter segment was offset by increased demand for CATV products from several existing customers. The increase in demand from CATV multiple-system operators ("MSOs") resulted in strong demand for our CATV products, especially those products that are related to architecture improvements to enable delivery of additional bandwidth to consumers.  This increase in bandwidth demand is particularly acute in the upstream direction, and sales of products associated with increased return-path bandwidth were notably strong in the quarter. Based on forecasts and current order bookings, we believe that this CATV demand will likely continue through 2021.

For the three months ended June 30, 2021 and 2020, our top ten customers represented 86.8% and 86.9% of our revenue, respectively. For the six months ended June 30, 2021 and 2020, our top ten customers represented 88.0% and 86.0% of our revenue, respectively. We believe that diversifying our customer base is critical for our future success, since reliance on a small number of key customers makes our ability to forecast future results dependent upon the accuracy of the forecasts we receive from those key customers. The growth in revenue from our top ten customers in the six months ended June 30, 2021 is primarily due to growth in our CATV segment. We continue to prioritize new customer acquisition and growth of diverse revenue streams.

Cost of goods sold decreased by $8.1 million, or 15.7%, for the three months ended June 30, 2021 as compared to the three months ended June 30, 2020, primarily due to 16.9% decrease in sales over the prior year. Cost of goods sold decreased by $3.2 million, or 3.8%, for the six months ended June 30, 2021 as compared to six months ended June 30, 2021, primarily due to 1.7% decrease in sales over the prior year.

Gross margin decreased for the three months ended June 30, 2021 as compared to the three months ended June 30, 2020 primarily as a result of changes in the mix of products in our datacenter and CATV segment. In particular, we saw an increase in sales of certain CATV products relative to sales of transceivers. This product mix resulted in overall changes in gross margin. Gross margin increased for the six months ended June 30, 2021 as compared to the six months ended June 30, 2020 primarily due to production inefficiencies, higher costs of certain raw materials in prior year at the beginning of the COVID-19 pandemic.

Research and development expense

Research and development expense slightly increased for the three months ended June 30, 2021 as compared to the three months ended June 30, 2020. Research and development expense increased by $0.5 million, or 2.3% for the six months ended June 30, 2021 as compared to the six months ended June 30, 2020. Research and development costs consist of R&D work orders, R&D material usage and other project related costs related to 100 Gbps, 200/400 Gbps data center products, DOCSIS 3.1 capable CATV products and other new product development, and depreciation expense resulting from R&D equipment investments. These increases were primarily due to an increase in costs from R&D work orders and repair and maintenance as a result of winter storm Uri.

Sales and marketing expense

Sales and marketing expense decreased by $0.6 million, or 17.4% for the three months ended June 30, 2021 as compared to the three months ended June 30, 2020 .  Selling and marketing expense decreased by 0.6 million, or 9.0% for the six months ended June 30, 2021 as compared to the six months ended June 30, 2020 . These decreases were primarily due to decrease in commission expenses and shipping and handling charges.

General and administrative expense

General and administrative expense slightly increased for the three months ended June 30, 2021 compared to the three months ended June 30, 2020. General and administrative expense increased by $0.3 million, or 1.4% for the six months ended June 30, 2021 compared to the six months ended June 30, 2020. These increases were primarily due to expense related to winter storm Uri. These increases were partially offset by a decrease in personnel-related costs, share-based compensation expense and professional service fees.

For the three months ended June 30, 2021, the effective tax rate varied from the federal statutory rate of 21% primarily due to the benefit of the nontaxable PPP loan forgiveness, offset by the change of the valuation allowance on federal, state, Taiwan, and China deferred tax assets ("DTA"). For the three months ended June 30, 2020, the effective tax rate varies from the federal statutory rate of 21% primarily due to the level and mix of earnings amount tax jurisdictions, and the change of the valuation allowance on the US and state DTA, and the recording of a valuation allowance on Taiwan deferred tax assets.

The Company’s effective tax rate for the six months ended June 30, 2021 and 2020 was 0% and (16.25%), respectively. For the six months ended June 30, 2021 , the effective tax rate varied from the federal statutory rate of 21% primarily due to the change of the valuation allowance on federal, state, Taiwan, and China DTA. For the six months ended June 30, 2020, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, the change of the valuation allowance on the US and state deferred tax assets, and the recording of a val uation on Taiwan deferred tax assets.

Liquidity and Capital Resources

As of June 30, 2021, we had $5.3 million of unused borrowing capacity from all of our loan agreements. As of June 30, 2021, our cash, cash equivalents and restricted cash totaled $50.5 million. Cash and cash equivalents are held for working capital purposes and are invested primarily in money market or time deposit funds. We do not enter into investments for trading or speculative purposes.

On October 24, 2019, we filed a Registration Statement on Form S-3 with the Securities and Exchange Commission, which was declared effective on January 9, 2020, providing for the public offer and sale of certain securities of the Company from time to time, at our discretion, up to an aggregate amount of $250 million.

On February 28, 2020, we entered into an Equity Distribution Agreement with Raymond James & Associates, Inc. (the “Sales Agent”) pursuant to which the Company may issue and sell shares of the Company’s common stock having an aggregate offering price of up to $55 million (the “Initial ATM Offering”), from time to time through the Sales Agent. In January 2021, the Company completed its Initial ATM Offering and sold 5.9 million shares at a weighted average price of $9.12 per share, providing proceeds of $53.9 million, net of expenses and underwriting discounts and commissions.

On February 26, 2021, we entered into another Equity Distribution Agreement (the “Agreement”) with the Sale Agent pursuant to which the Company may issue and sell shares of the Company’s common stock, par value $0.001 per share (the “Shares”) having an aggregate offering price of up to $35 million (the “Second ATM Offering”), respectively, from time to time through the Sales Agent. Upon delivery of a placement notice and subject to the terms and conditions of the Agreement, sales, if any, of the Shares will be made through the Sales Agent in transactions that are deemed to be “at the market” offerings as defined in Rule 415 of the Securities Act of 1933, as amended (the “Securities Act”), including sales made through the facilities of the Nasdaq Global Market, the principal trading market for the Company’s common stock, on any other existing trading market for the Company’s common stock, to or through a market maker or as otherwise agreed by the Company and the Sales Agent. In the placement notice, the Company will designate the maximum number of Shares to be sold through the Sales Agent, the time period during which sales are requested to be made, the minimum price for the Shares to be sold, and any limitation on the number of Shares that may be sold in any one day. Subject to the terms and conditions of the Agreement, the Sales Agent will use its commercially reasonable efforts to sell Shares on the Company’s behalf up to the designated amount specified in the placement notice. The Company has no obligation to sell any Shares under the Agreement and may at any time suspend offers and sales of the Shares under the Agreement.

The Agreement provides that the Sales Agent will be entitled to compensation of up to 2% of the gross sales price of the Shares sold through the Sales Agent from time to time. The Company has also agreed to reimburse the Sales Agent for certain specified expenses in connection with the registration of Shares under state blue sky laws and any filing with, and clearance of the offering by, the Financial Industry Regulatory Authority Inc., not to exceed $10,000 in the aggregate, and any associated application fees incurred. Additionally, if the Agreement is terminated under certain circumstances, and the Company fails to sell a minimum amount of the Shares as set forth in the Agreement, then the Company has agreed to reimburse the Sales Agent for reasonable out-of-pocket expenses, including the reasonable fees and disbursements of counsel incurred by the Sales Agent, up to a maximum of $30,000 in the aggregate. The Company agreed to indemnify the Sales Agent against certain liabilities, including liabilities under the Securities Act, or to contribute to payments that the Sales Agent may be required to make because of any of those liabilities.

In March 2021, we commenced sales of common stock through the Second ATM Offering. The details of the shares of common stock sold through the Second ATM Offering through June 30, 2021 are as follows (in thousands, except shares and weighted average per share price):

As of June 30, 2021 , the total gross sales were $0.9 million and thus remaining amount of common stock we have available to sell under the ATM Offering is $34.1 million.

On March 5, 2019, the Company issued $80.5 million of 5% convertible senior notes due 2024, bearing interest at a rate of 5% per year maturing on March 15, 2024, unless earlier repurchased, redeemed or converted in accordance with their terms. The sale of the Notes generated net proceeds of $76.4 million, after expenses. Also refer to Note 12 “Convertible Senior Notes” to the consolidated financial statements for further discussion of the Notes.

Net cash used in operating activities consisted of our net loss of $23.8 million after exclusion of non-cash items of $21.9 million. Cash decreased due to an increase in accounts receivable and trade receivables from our customers of $5.4 million and $3.4 million, respectively, a decrease in accrued liabilities of $3.1 million, a decrease in accounts payable to our vendors of $3.9 million, offset by a decrease in inventory of $8.9 million.

For the six months ended June 30, 2020, net cash used in operating activities was $23.8 million. Net cash used in operating activities consisted of our net loss of $35.4 million after exclusion of non-cash items of $27.1 million.

For the six months ended June 30, 2020, net cash used in investing activities was $9.2 million, mainly from the purchase of additional plant, machinery and equipment.

Financing activities

For the six months ended June 30, 2021 , our financing activities provided $19.8 million in cash. This increase in cash was due to $15.3 million of net proceeds from our At The Market (ATM) Offerings, $16.6 million proceeds from line of credit, offset by repayment of loan and bank acceptance of $2.2 million and $9.5 million, respectively.

For the  six months ended June 30, 2020, our financing activities provided $25.1 million in cash. This increase in cash was due to $13.9 million of net proceeds from our At The Market (ATM) Offering, $6.2 million proceeds from PPP term loan, $1.7 million net proceeds from lines of credit and $3.7 million net proceeds from acceptances payable.

Loans and commitments

We have lending arrangements with several financial institutions. In the US, we have a revolving line of credit with Truist Bank. The line of credit contains financial covenants that may limit the amount and types of debt that we may incur. As of June 30, 2021, we were in compliance with these covenants.

In Taiwan, we have a revolving credit facility with Taishin International Bank and equipment finance agreements with Chailease Finance Co., Ltd. for Prime World’s Taiwan Branch. In China, we have revolving lines of credit with China Merchants Bank Co., Ltd. and Shanghai Pudong Development Bank Co., Ltd. and credit facilities with China Zheshang Bank Co., Ltd. for our China Subsidiary, Global.

As of June 30, 2021, we had $5.3 million of unused borrowing capacity.

On March 5, 2019, we issued $80.5 million of 5% convertible senior notes due 2024. The Notes will mature on March 15, 2024, unless earlier repurchased, redeemed or converted in accordance with their terms.

See Note 11 “Notes Payable and Long-term Debt” and Note 12 “Convertible Senior Notes” of our Condensed Consolidated Financial Statements for a description of our notes payable and long-term debt and convertible senior notes.

China factory construction

On February 8, 2018, we entered into a construction contract with Zhejiang Xinyu Construction Group Co., Ltd. for the construction of a new factory and other facilities at our Ningbo, China location. Construction costs for these facilities under this contract are estimated to total approximately $27.5 million.  As of June 30, 2021, construction of the building is complete, and approximately $27.4 million of this total cost has been paid and the remaining portion will be paid in yearly installments for three years after final inspection. We anticipate additional expenses for building improvements to the factory and we are in the process of evaluating the timing of these expenditures and obtaining bids for any such work.

Future liquidity needs

We believe that our existing cash and cash equivalents, cash flows from our operating activities, and available credit will be sufficient to meet our anticipated cash needs for the next 12 months. Our future capital requirements will depend on many factors including our growth rate, the timing and extent of spending to support our research and development efforts, the expansion of our sales and marketing activities, the introduction of new and enhanced products, the building improvement of a new factory and other facilities at our Ningbo, China location, changes in our manufacturing capacity and the continuing market acceptance of our products.  In the event we need additional liquidity, we will explore additional sources of liquidity. These additional sources of liquidity could include one, or a combination, of the following: (i) issuing equity or debt securities, (ii) incurring indebtedness secured by our assets and (iii) selling product lines, other assets and/or portions of our business. There can be no guarantee that we will be able to raise additional funds on terms acceptable to us, or at all.

We issued convertible senior notes due 2024. The amount present in the table represents the principal portion and estimated interest expense for the obligations.

Inflation

We believe that the relatively low rate of inflation in the U.S. over the past few years has not had a significant impact on our net sales and revenues or on income from continuing operations or on the prices of raw materials. To the extent we expand our operations in China and Taiwan, such actions may result in inflation having a more significant impact on our operating results in the future.

Off-Balance Sheet Arrangements

For the six months ended June 30, 2021, we did not, and do not currently, have any off-balance sheet arrangements.

Critical Accounting Policies and Estimates

In our Annual Report for the year ended December 31, 2020 and in the Notes to the Financial Statements herein, we identify our most critical accounting policies. In preparing the financial statements, we make assumptions, estimates and judgments that affect the amounts reported. We periodically evaluate our estimates and judgments that are most critical in nature which are related to revenue recognition, allowance for credit losses, inventory reserves, impairment of long-lived assets (excluding goodwill and other indefinite-lived intangible assets), goodwill and other indefinite-lived intangible assets, purchase price allocation of acquisitions, service and product warranties, and income taxes. Our estimates are based on historical experience and on our future expectations that we believe are reasonable. The combination of these factors forms the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results are likely to differ from our current estimates and those differences may be material.

Item 3.   Quantitative and Qualitative Disclosures about Market Risk

For quantitative and qualitative disclosures about market risk affecting the Company, see Item 7A – Quantitative and Qualitative Disclosures about Market Risk in our Annual Report for the fiscal year ended December 31, 2020. We do not believe the Company’s exposure to market risk has changed materially since December 31, 2020.

Item 4.   Controls and Procedures

The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their control objectives.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2021. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the three month period covered by this Quarterly Report on Form 10-Q, which were identified in connection with management’s evaluation required by the Rules 13a-15(d) and 15d-15(d) under the Exchange Act that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
