NOTE C—REVENUE RECOGNITION

  

Revenue from Contracts with Customers

    

The Company derives revenue from the manufacture and sale of fiber optic networking products. Revenue is recognized when obligations under the terms of a contract with its customer are satisfied; generally this occurs with the transfer of control of products or services. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or providing services. Certain customers may receive cash and/or non-cash incentives, which are accounted for as variable consideration. To achieve this core principle, the Company applies the following five steps:

  

1. Identify the contract with a customer

  

A contract with a customer exists when (i) the Company enters into an agreement with a customer that defines each party's rights regarding the products or services to be transferred and identifies the payment terms related to these products or services, (ii) both parties to the contract are committed to perform their respective obligations, (iii) the contract has commercial substance, and (iv) the Company determines that collection of substantially all consideration for products or services that are transferred is probable based on the customer's intent and ability to pay the promised consideration. The Company applies judgment in determining the customer's ability and intention to pay, which is based on a variety of factors including the customer's payment history or, in the case of a new customer, published credit and financial information pertaining to the customer.

  

2. Identify the performance obligations in the contract

  

Performance obligations promised in a contract are identified based on the products or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the product or service either on its own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the products or services is separately identifiable from other promises in the contract. To the extent a contract includes multiple promised products or services, the Company must apply judgment to determine whether promised products or services are capable of being distinct and distinct in the context of the contract. If these criteria are not met, the promised products or services are accounted for as a combined performance obligation. The Company has elected to account for shipping and handling activities as a fulfillment cost as permitted by the standard.

  

3. Determine the transaction price

  

The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring products or services to the customer. To the extent the transaction price is variable, revenue is recognized at an amount equal to the consideration to which the Company expects to be entitled. This estimate includes customer sales incentives which are accounted for as a reduction to revenue and estimated using either the expected value method or the most likely amount method, depending on the nature of the program. The Company will adjust its consideration for any rebates if it is more likely than not that the rebate conditions will be met.

  

4. Allocate the transaction price to performance obligations in the contract

  

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price for each performance obligation. The Company determines standalone selling price based on the price at which the performance obligation is sold separately.

 

In cases where there is no directly observable stand alone selling price, allowable estimation methods are used. For example for contracts involving non-recurring engineering, an expected cost plus margin approach has typically been adopted to estimate the standalone selling price.

  

5. Recognize revenue when or as the Company satisfies a performance obligation 

  

For product sales, the Company generally satisfies performance obligations at a point in time, most often upon shipment of a product to the customer or delivery of the product to the customer.  In the case of such point in time satisfaction of a performance obligation, revenue is recognized based on the transaction price at the time the related performance obligation is satisfied.

 

For service obligations, the Company generally recognizes revenue over time. The most common type of service obligation encountered by the Company is an arrangement involving non-recurring engineering in which service revenue is typically recognized over time under either the time and material practical expedient, as the Company has a right to consideration from a customer, in an amount that corresponds directly with the value to the customer of the Company's performance completed to date, or under the output method, for example using contract-specific milestones or other objective measures of progress.

 

Disaggregation of Revenue 

  

Revenue is classified based on the location of where the product is manufactured. For additional information on the disaggregated revenues by geographical region, see Note R, "Segments and Geographic Information."

Customer Warrant

 

 On March 13, 2025, the Company issued a warrant (the "Customer Warrant") to a wholly-owned subsidiary of Amazon.com, Inc. to purchase up to an aggregate of 7,945,399 shares of the Company's common stock ("Warrant Shares") at an exercise price of $23.6956 per share. The Customer Warrant has a contractual term of 10 years. At the time of the issuance, the Customer Warrant is exercisable to purchase 1,324,233 Warrant Shares. The remaining 6,621,166 Warrant Shares may vest over the next 10 years, dependent on aggregate purchases by or on behalf of Amazon and its affiliates of $4 billion of the Company's products over this time period. The Company accounts for the Customer Warrant as an equity classified share-based consideration to a customer and will recognize the grant-date fair value of the Customer Warrant as a reduction of revenue from Amazon as the related goods or services are transferred. The grant date fair value of the Customer Warrant was determined to be $12.64 per share, using the Black-Scholes-Merton option pricing model. 

 

 The per share grant date fair value of the Customer Warranty was estimated using the following assumptions:

 

  At Grant Date 
Expected volatility  80.00%
Weighted-average expected term (in years)  10 
Risk-free interest rate  4.23%
Dividend yield  -%
Fair Value per ordinary share at grant date  15.87 

 

For the year ended December 31, 2025, the Company recognized approximately $33.1 million of revenue associated with customer arrangements that included the issuance of warrants. The impact of these arrangements on the Company's consolidated financial statements was not material for the periods presented. As of December 31, 2025, the Company recorded other current asset of $1.0 million and other noncurrent asset of $15.0 million, representing the aggregate grant-date fair value of 1,324,233 Warrant Shares vested at the issuance.

About Revenue Disclosures

Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.

Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
